Description

Technical Field

[0001] This invention relates to automobiles, and more specifically to a vehicle body hinge, a hinge assembly, and an automobile. Background Technology

[0002] A hinge assembly typically includes a body hinge, a door hinge, and a hinge shaft. The body hinge and door hinge are hinged together via the hinge shaft. Due to the simple manufacturing process and low cost of stamped parts, many automobile manufacturers use stamped body hinges and stamped door hinges. For example, the side door hinge structure and vehicle proposed in patent application number CN201420754334.3 use stamped hinges for both the body hinge and the door hinge.

[0003] The conventional hinge assemblies in the prior art have the following technical problems:

[0004] Traditional stamped car body hinges are typically formed by a base plate, front side plate, left side plate, and right side plate. During the stamping process of traditional stamped car body hinges, the raw material undergoes significant stretching and deformation, making it difficult to guarantee the quality of the parts.

[0005] Traditional stamped body hinges are single-layer components. Directly increasing the opening angle of the traditional hinge assembly will make it difficult for the traditional stamped body hinge to meet the strength requirements. At the same time, it will also increase the requirements for layout space and increase the restrictions on the shape of the door. Therefore, the opening angle of the traditional hinge assembly is usually below 75°, which is difficult to meet the requirements for large-angle opening of the door. Summary of the Invention

[0030] The embodiments of the present invention will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are only for illustrating the present invention and not for limiting the scope of protection of the present invention.

[0031] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of the present invention. Therefore, the drawings only show the components related to the present invention and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0032] like Figures 1 to 5The vehicle body hinge 1 shown is a one-piece molded part, comprising a first base plate portion 101, a first side plate portion 102, a second side plate portion 103, a third side plate portion 106, a first flange portion 104, and a second flange portion 108. The lower edge of the first side plate portion 102 is connected to the front edge of the first base plate portion 101, and the first side plate portion 102 is bent upward relative to the first base plate portion 101. The front edge of the second side plate portion 103 is connected to the front edge of the first side plate portion 104. The left edge of the first side plate 102 is connected to the second side plate 103, which is bent backward relative to the first side plate 102; the front edge of the third side plate 106 is connected to the right edge of the first side plate 102, and the third side plate 106 is bent backward relative to the first side plate 102; the right edge of the first flange 104 is connected to the lower edge of the second side plate 103, and the first flange 104 is bent to the left relative to the second side plate 103, and the first flange 104 is stacked on the left side of the first bottom plate 101. The upper side; the left edge of the second flange 108 is connected to the lower edge of the third side plate 106, the second flange 108 is bent to the right relative to the third side plate 106, and the second flange 108 is stacked on the upper side of the right side of the first base plate 101; a first through hole 105 is provided on the first flange 104, a second through hole 107 is provided on the second flange 108, and a third through hole 112 corresponding to the first through hole 105 is provided on the left side of the first base plate 101. Hole 105 and third through hole 112 constitute a first mounting hole for connection with the vehicle body. A fourth through hole 113 corresponding to the second through hole 107 is provided on the right side of the first base plate portion 101. The second through hole 107 and the fourth through hole 113 constitute a second mounting hole for connection with the vehicle body. A first connecting hole 114 for connection with the hinge shaft 3 is provided on the upper part of the second side plate portion 103. A second connecting hole 115 for connection with the hinge shaft 3 is provided on the upper part of the third side plate portion 106.

[0033] By adopting the above technical solution and rationally setting the structure of the body hinge 1, firstly, by having the first flange 104 stacked on the upper left side of the first base plate 101 and the second flange 108 stacked on the upper right side of the first base plate 101, the structural strength of the stamped body hinge 1 is improved. After the body hinge 1 is installed on the vehicle body, both the first flange 104 and the second flange 108 can form at least three layers of stacked structure, which can improve the structural strength of the body hinge 1 and the body connection structure; secondly, as Figure 4As shown, by improving the structural strength of the body hinge 1, the distance e between the first mounting hole and the hinge shaft 3 in the front-rear direction can be made smaller, the distance e between the second mounting hole and the hinge shaft 3 in the front-rear direction can be made smaller, and the distance f between the first floor and the hinge shaft 3 in the vertical direction can be made larger. This is beneficial for increasing the maximum opening of the hinge assembly and also reduces the space requirement for the stamped body hinge 1. Thirdly, the body hinge 1 is formed by bending, which has the characteristics of simple process, low cost and high manufacturability, reducing the manufacturing difficulty of the body hinge 1. Fourthly, compared to the conventional body hinge 1 in the prior art, which requires a large included angle at the corner to ensure forming quality, the above-mentioned body hinge 1 is formed by bending, which imposes fewer restrictions on the included angle between the first base plate portion 101 and the first side plate portion 102. This facilitates reducing the distance between the first mounting hole and the hinge shaft 3 in the front-rear direction, and also facilitates reducing the distance between the second mounting hole and the hinge shaft 3 in the front-rear direction. This helps to increase the maximum opening of the hinge assembly and reduces the space requirement for the stamped body hinge 1.

[0034] like Figure 7 As shown and Figure 8 As shown, compared with the conventional hinge assembly 6, the hinge assembly of the above-mentioned body hinge 1 can be set closer to the hinge shaft 3 in the front-rear direction than the conventional mounting hole 601 of the conventional hinge assembly 6. The distance between the first mounting hole and the conventional mounting hole 601 in the front-rear direction is h. The hinge assembly of the above-mentioned body hinge 1 is more likely to meet the safety clearance requirements between the door motion envelope and the hinge mounting bolt.

[0035] In some embodiments, the first side plate portion 102 is perpendicular to the first bottom plate portion 101. The above-described technical solution helps to reduce the distance between the first mounting hole and the hinge shaft 3 in the front-rear direction, helps to reduce the distance between the second mounting hole and the hinge shaft 3 in the front-rear direction, helps to increase the maximum opening of the hinge assembly, and reduces the space requirements for the stamped body hinge 1.

[0036] In some embodiments, the second side plate portion 103 is perpendicular to the first side plate portion 102, the third side plate portion 106 is perpendicular to the first side plate portion 102, the first flange portion 104 is perpendicular to the second side plate portion 103, and the second flange portion 108 is perpendicular to the third side plate portion 106. Adopting the above technical solution helps reduce the molding difficulty of the vehicle body hinge 1 and improves the structural accuracy of the vehicle body hinge 1.

[0037] In some embodiments, the upper part of the second side plate portion 103 is provided with a first lug 109 extending upward from the first side plate portion 102, and a first connecting hole 114 is provided on the first lug 109; the upper part of the third side plate portion 106 is provided with a second lug 110 extending upward from the first side plate portion 102, and a second connecting hole 115 is provided on the second lug 110. By adopting the above technical solution, the first lug 109 and the second lug 110 provide space for the rotation of the door hinge 2.

[0038] In some embodiments, the vehicle body hinge 1 is formed by punching and bending a single sheet of material. For example... Figure 6 As shown, the vehicle body hinge 1 can be formed by punching and bending a single sheet of material to create a stamped vehicle body hinge 1, which is easy to manufacture and has low cost.

[0039] In some embodiments, the diameter of the third through hole 112 is larger than the diameter of the first through hole 105, and the diameter of the fourth through hole 113 is larger than the diameter of the second through hole 107. By adopting the above technical solution, the installation difficulty can be reduced.

[0040] In some embodiments, the present invention also provides a hinge assembly, such as Figures 1 to 5 As shown, the hinge assembly includes a door hinge 2, a hinge shaft 3, and a body hinge 1 as described in any of the above. The two ends of the hinge shaft 3 are respectively connected to the first connecting hole 114 and the second connecting hole 115. The door hinge 2 is hinged to the body hinge 1 through the hinge shaft 3.

[0041] In some embodiments, the door hinge 2 includes a second base plate portion 201, a fourth side plate portion 202, a fifth side plate portion 205, a third flange portion 203, and a fourth flange portion 206; the rear edge of the fourth side plate portion 202 is connected to the left edge of the second base plate portion 201, and the fourth side plate portion 202 is bent forward relative to the second base plate portion 201; the rear edge of the fifth side plate portion 205 is connected to the right edge of the second base plate portion 201, and the fifth side plate portion 205 is bent forward relative to the second base plate portion 201. The right edge of the third flange 203 is connected to the front edge of the fourth side plate 202. The third flange 203 is bent to the left relative to the fourth side plate 202, and a fifth through hole 204 for connecting with the door 7 is provided on the third flange 203. The left edge of the fourth flange 206 is connected to the front edge of the fifth side plate 205. The fourth flange 206 is bent to the right relative to the fifth side plate 205, and a sixth through hole 207 for connecting with the door 7 is provided on the fourth flange 206. Using the above technical solution, the door hinge 2 can be manufactured by punching and bending, which has the characteristics of simple manufacturing and low cost. In specific implementation, by reasonably setting the structure of the body hinge 1 and the door hinge 2, the adjustable range of dimensions c and d is large, which can realize the commonality of parts such as the door hinge 2 and the hinge shaft 3, and helps to reduce mold costs.

[0042] As a preferred example, both the fourth side plate portion 202 and the fifth side plate portion 205 are provided with hinge holes that mate with the hinge shaft 3, and a bushing that serves a lubricating function can be provided between the hinge hole and the hinge shaft 3.

[0043] In some embodiments, the upper edge of the first base plate portion 101 is provided with an upwardly protruding first limiting portion 111, and the lower edge of the second base plate portion 201 is provided with a downwardly protruding second limiting portion 208. The first limiting portion 111 and the second limiting portion 208 limit the maximum opening angle g of the hinge assembly. Using the above technical solution, the first limiting portion 111 can avoid the door hinge, and the maximum opening of the hinge assembly can be adjusted by adjusting the protrusion height of the second limiting portion 208, providing convenience for increasing the maximum opening of the hinge assembly.

[0044] In practice, the body hinge 1 can be fixedly connected to the body using two first bolts 4 that mate with the first mounting hole and the second mounting hole respectively, and the door hinge 2 can be fixedly connected to the door using two second bolts 5 that mate with the fifth through hole 204 and the sixth through hole 207 respectively.
