automotive hinge assembly

This invention calls for hinges, more particularly to hinges of automobiles, that facilitates the movement of a closure panel relative to a fixed body, and simplify configuration of components constitutive promoters utilizing a single hinge construction of multiple pieces.Background of the invention hinges are generally configured to automobiles include a port that is rigidly attached with a closure panel and a bodywork component which is rigidly attached with a body structure. This attachment structural components can be achieved by soldering, riveting, screwing or the like mechanical fastening means. The simple rotating component port component relative to the bodywork is normally met by a pivot pin and associated support surfaces. The pivot pin is configured to be rigidly attached to harder with hinge components while the other component freely rotates around the pivot pin through one or more support surfaces. Practice normal to utilize two such hinge, vertically offset with coaxially aligned pivot pins, for securing a closure panel to a body.Automotive body components and a hinge port automotive are commonly constructed from steel or aluminum using stamping, forging, molding, extrusion or roll-conformation.Each component is generally configured with one or more mounting surfaces and a pair of arms pivot holes containing pivot axes. The pivot arms are structurally connected via some form of bridge or by mounting surface. It is common practice to create the required support surface pivot mounting means for lifting inserts the holes for pivot axes of the door component. A pivot pin is inserted through the robes pivot door component is structurally attached with the bodywork component through holes pivot axes using

, adjustments with clamping, riveting, crimping or similar means of clamping material. The bodywork component is structurally attached with a automotive vehicle structure through its mounting surface using screwing, welding, gluing, riveting or similar fastening means. The port component is similarly structurally fitted with a closure panel vehicle through its mounting surface using screwing, welding, gluing, riveting or similar fastening means.Hinge systems typically utilize a riveted automobile minimum of two fixing for hinge component.Complex formations are, therefore, required to provide the necessary hole locations pivot axis, mounting surfaces, structural integrity, locations of fixing and shifts blousy in a one piece component. Forgings gave and molding are well-suited to provide these shapes necessarily complex, but suffer a significant penalty cost in comparison with metal stamping press formed. Metal stamping is generally considered the most expensive method of creating hinge components, but the shape of the formation is limited. Further, complex configurations generally result in large quantities of material

, unused, produce during the shaping process in press.Figure 1 illustrates one form of prior art common upon completion of a hinge (1) automotive, configured of a bodywork component (2) shaped press, a component shaped port (3) press, a pivot pin (4) and two (25) robes pivot (26). The component (2) body is configured with a pair of arms (6) pivot (7) and a large mounting surface (8) that is adapted to be structurally attached with a vehicular body through mounting holes (9) (10) and two corresponding threaded fixing.These mounting holes (10) (9) are spaced a suitable distance to ensure sufficient charge spreading to the vehicle body structure. The arms pivot (6) (7) are configured with a pair of holes (11) pivot (12) adapted to accept and rigidly capture the pivot pin (4) through

recartilhagem

, adjustments with clamping, riveting, crimping or similar means of clamping material. The distance from the mounting holes (9) (10) to the holes (11) pivot (12) is dictated by the configuration of the closure panel and the vehicle bodywork and may be substantial. The component (3) port is configured with a pair of arms (13) pivot (14), a structural bridge (21) and a pair of mounting surfaces (15) (16) that are adapted to be structurally secured with a closure panel vehicle through mounting holes (17) (18) and two corresponding threaded fixing. These mounting holes (17) (18) are spaced a suitable distance to ensure sufficient charge spreading for vehicular closure panel. The arms pivot (13) (14) are configured with a pair of holes (19) pivot (20) adapted to accept robes (25) pivot (26) that facilitate rotation around the pivot pin (4). The distance from the mounting holes (17) (18) to the holes (19) pivot (20) is dictated by the configuration of closure panel and the vehicle bodywork and may be substantial. Both the component (2) and automotive body component (3) port are shaped in press from sheet steel flat and, due to their complex forms, a significant amount of waste material is created during the stamping process. Figure 2 illustrates the layout of the blank flat both component (2) body prior art and component (3) port and the waste material (22) shown in phantom associated with the stamping process. In spite of the considerable waste material (22) generated in this configuration, the manufacturing technique for conformation is still very effective press more cost effective, than molding or forging.OThe invention hence, would be advantageous to create a set of hinge that is constructed using metal shaped pieces printed press, but that reduces or eliminates the waste associated with the complex forms, dictated by configuration of closure panel and the vehicle bodywork. Large proportions of material used and

conformation in press a hinge component can be directly attributed to the complexity of form dictated by the required distances between the mounting holes and features support pivot pin.Would be, hence, a significant improvement over the existing art, if the interconnection of these features could be reached in a more efficient manner.The present invention aims at reducing the total material utilized in hinge components formed of metal, stamped, by utilizing the pivot pin as a component main body. In a conventional automobile door hinge utilizing a port of a component piece automotive body component and one piece, pivot pin performs two major roles as it assembles the two components while structurally facilitates relative rotary motion between them. The present invention utilizes the pivot pin to a main function insofar as it additional structurally connects multiple pieces also of each individual component. A door component single piece, conventionally manufactured, patterned press, normally connects its two mounting surfaces and two arms pivot via a bridge integral body. The present invention eliminates the structural bridge and configures each mounting surface is associated pivotal arm as a support formed angled press, separate, individually, and structurally

referring to Figures 3, 4, 5, and 6, a set of hinge (30) automotive is substantially constructed of a component (40) port and a bodywork component (60). The port component is configured with a mounting surface (41) and two arms (42) pivot. Each pivotal arm (42) contains a hole (43) pivot axis. The component (40) port is structurally attached to a closure panel (27) vehicle through its mounting surface (41) using screwing, welding, gluing, riveting or similar fastening means. The bodywork component (60) is configured with a mounting surface (61) and a pivotal arm (62). Pivotal arm (62) contains a hole (63) pivot axis. The bodywork component is structurally attached to an automotive vehicle structure (28) through its mounting surface (61) using screwing, welding, gluing, riveting or similar fastening means. The hole (63) pivot axis component (60) is provided bodywork with a pivot bushing (80) that contains a support surface (81) internal cylindrical and two flanges (82) opposing thrust. Referring to Figure 7, a pivot pin (90) is configured with a cylindrical pivot surface (91) center and two ends (92) opposing cylindrical

are adapted to be inserted into and structurally connected with holes (43) pivot axis component (40) port through riveting, crimping or similar means of clamping material, in this manner, the component (40) and door component (60) automotive body are maintained in structural mounting, but are free to rotate relative to one another.Referring to Figure 8, the component (40) port is constructed of two angular shaped supports (46) press (47) that are, both, configured with a mounting surface (41) and a pivotal arm (42). The pivot arms (42), each, contain a hole (43) pivot axis. When the two ends (92)

recartilhadas

opposing cylindrical pivot pin (90) are pressed into holes (43) pivot axes and structurally secured through riveting, crimping or similar means of clamping material, a single component (40) is unitary port created. The pivot pin (40), hence, replaces the structural bridge normally required to create a single unitary port component, significantly reducing the amount of material required and associated cost.Referring to Figure 9, the automotive body component (60) is constructed of two supports angled shaped body (66) press (67) that are, both, configured with a mounting surface (61) and a pivotal arm (62). The arms pivot (62), each, contain a hole (63) pivot axis. The two holders (66) angled bodywork (67) are configured such that the two arms (62) pivot are permutated surface with surface and aligned through a feature (68) provided

semicisalhamento

within the conjugation of alignment hole (69). When the characteristic of semi-shear (68) is structurally connected within the alignment hole (69) by snap-fit, welding, gluing, riveting, crimping or similar means of clamping material, a single unitary body component (60) is created.The semi-shear (68) and (69) alignment hole are arranged such that the holes for pivot axes (63) are in alignment. The hole (63) pivot axis is provided with a bushing (80) pivot containing a support surface (81) internal cylindrical and two flanges (82) opposing thrust. In this manner, the two holders angular shaped automotive press (66) (67) create a single unitary port component, significantly reducing the amount of material required and associated cost in comparison with a configuration in one piece.Figure 10 illustrates the flat blank layout of both the backing angular shaped automotive press (66) (67) angular shaped supports (46) press (47) of the present invention as well as the waste material (58) associated with the stamping process. In comparison with the blank layout of the flattened prior art hinge assembly, illustrated in Figure 2, it is evident that the present invention provides superior material total and lesser level of waste that the configuration of the prior art.In one form of preferred embodiment of the present invention, a pair of hinge stop formations (70) is provided in the arms pivot (62) of the rack (66) angled bodywork (67), which is adapted to interact with a pair of stop surfaces (50) hinge provided in the arms pivot (42) or supports (46) angled port (47). When the set of door hinge (30) is rotated into its fully opened position, the stop surfaces (50) hinge contact formations stop hinge (70) and prevent further rotation.Figure 11 illustrates a test upon completion alternative pivot pin (100) of the present invention, which incorporates two cylindrical ends (102) that are opposing

or

supercomprimidos

, resulting in inadequate structural mounting or deficient relative rotation motion. The steps (105) of the form

(113) and the surface (111) cylindrical pivot center. In this manner, the process of mounting the assembly (30) automotive hinge simplifies to insertion and riveting, crimping or similar means clamping of material from a single pivot pin (110) of one end. A slight degradation of structural attachment of the two angular supports (46) door (47) may occur using this configuration.Figures 13 and 14 illustrate an alternative form of the present invention upon completion wherein the pivot pin (190) is configured to facilitate separation of the component (140) and door component (160) body. This type of separation and reassembly is required in some vehicle assembly plants, and is generally referred to as a process moving upright. Both Component (140) and door component (160) automotive body are constructed in the same manner as in the form of major upon completion of the present invention with two angular shaped supports (146) press (147) and two supports angled shaped body (166) press (167). Nevertheless, pivot pin (190) is configured to be structurally connected with the two holders (146) angled port (147) through a pivot bushing (180) and washer (184) through riveting, crimping or similar means of clamping material. The end of the pivot pin (190), opposite the clamping washer is material, is configured with a characteristic (195) and
