Existing vehicle body hinges still have some shortcomings. Traditional hinges have complex structures and are difficult to assemble. Some use stamping or welding structures, which are not strong enough and are prone to wear and loosening after long-term use, affecting service life and user experience. Moreover, under the trend of vehicle body lightweighting, existing hinges have shortcomings in the "strength and lightweight balance" and cannot meet the requirements of high strength and lightweight at the same time.

[0003] Therefore, it is necessary to design a body hinge profile to solve the problems mentioned above. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle body movable hinge profile, comprising a first hinge profile and a second hinge profile; the first hinge profile includes a first mounting end, one end of which is integrally formed with a first arc-shaped end, and the end of the first arc-shaped end away from the first mounting end is integrally formed with a first hook-shaped end, and at least one first mounting hole is provided on the first mounting end for connection with a vehicle body fixed component; the second hinge profile includes a second mounting end, one end of which is integrally formed with a second arc-shaped end, and the end of the second arc-shaped end away from the second mounting end is integrally formed with a second hook-shaped end, and at least one second mounting hole is provided on the second mounting end for connection with a vehicle body movable component; the first hook-shaped end and the second hook-shaped end are nested together to form a rotatable connection, and the curvature of the first arc-shaped end is adapted to the curvature of the second arc-shaped end, the two working together to form a rotational guide structure.

[0006] Furthermore, both the first hinge profile and the second hinge profile are made of all-metal or all-resin materials to meet the strength and lightweight requirements of different scenarios.

[0007] Furthermore, the mating surfaces of the first hook-shaped end, the first arc-shaped end, the second arc-shaped end, and the second hook-shaped end are all provided with a wear-resistant coating to improve the wear resistance of the rotating mating parts and extend their service life.

[0008] Furthermore, a lubrication groove is provided at the mating point between the first arc-shaped end and the second arc-shaped end to store lubricant such as grease, reduce rotational resistance, and ensure smooth rotation.

[0009] Furthermore, reinforcing ribs are provided on the first and second mounting ends respectively to enhance the structural rigidity of the mounting ends and prevent deformation due to stress after installation.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The structure of this utility model is simple and modular. It can be installed by fasteners (such as bolts) through the first mounting hole and the second mounting hole. The assembly process is simple, reducing production time and assembly difficulty.

[0011] 2.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings. Several embodiments of this utility model are provided. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of this utility model will be more thorough and complete.

[0021] Example 1

[0022] Please see Figure 1-5 This embodiment provides a vehicle body movable hinge profile for realizing the rotational connection between fixed parts and movable parts (such as doors and vehicle frames) of the vehicle body. Its structure is shown in the figure, including a first hinge profile 1 and a second hinge profile 2. The first hinge profile 1 includes a first mounting end 101 for connecting to the vehicle body fixed structure. One end of the first mounting end 101 (the side away from the vehicle body fixed structure) extends to form a first arc-shaped end 102, with a smooth arc surface. The end of the first arc-shaped end 102 away from the first mounting end 101 bends inward to form a first hook-shaped end 103. The first hook-shaped end 103 has a "hook" structure, with the inner side of the hook head being an arc surface adapted to the rotation trajectory. A first mounting hole 104 is provided along the length direction on the first mounting end 101 for inserting bolts for fixing. The second hinge profile 2 includes a second mounting end 104. The second mounting end 201 is used to connect with the moving structure of the vehicle body. One end of the second mounting end 201 (the side away from the moving structure of the vehicle body) extends to form a second arc-shaped end 202, and the arc surface of the second arc-shaped end 202 can fit with the arc surface of the first arc-shaped end 102. The end of the second arc-shaped end 202 away from the second mounting end 201 is bent to form a second hook-shaped end 203. The second hook-shaped end 203 is a "hook-shaped" structure adapted to the first hook-shaped end 103. The outer side of the hook head is an arc surface. A second mounting hole 204 is provided on one side of the second mounting end 201 for passing through bolts to achieve fixation. The first hook-shaped end 103 and the second hook-shaped end 203 are nested in each other, and their contact surfaces can slide relative to each other. At the same time, the outer arc surface of the first arc-shaped end 102 and the inner arc surface of the second arc-shaped end 202 fit together to form a guide, which together realizes the rotational connection between the first hinge profile 1 and the second hinge profile 2.

[0023] Example 2

[0024] Please see Figure 1-5Based on Embodiment 1, this embodiment further defines the molding method and material of the first hinge profile 1 and the second hinge profile 2. The first hinge profile 1 and the second hinge profile 2 are integrally molded structures to ensure the connection strength of the three and that the overall structure has no weak points. The materials of the first hinge profile 1 and the second hinge profile 2 are either all-metal materials or all-resin materials. If all-metal materials are selected, it is suitable for vehicle body structures that need to balance strength and lightweight. If all-resin materials are selected, it is suitable for vehicle body structures with high lightweight requirements and corrosive environments.

[0025] Example 3

[0026] Please see Figure 1-5 Based on Embodiment 1, this embodiment further limits the number of the first mounting hole 104 and the second mounting hole 204. The number of the first mounting hole 104 and the second mounting hole 204 is at least one. This is set according to the stress requirements of the vehicle body fixing structure, which can improve the versatility of this utility model and ensure the connection stability with the vehicle body moving structure.

[0027] Example 4

[0028] Please see Figure 1-5 Based on Example 1, this embodiment further limits the wear resistance of the rotating mating surfaces and the fitting accuracy and lubrication performance of the arc-shaped ends. The mating surfaces of the first hook-shaped end 103 and the second hook-shaped end 203, and the mating surfaces of the first arc-shaped end 102 and the second arc-shaped end 202 (i.e., all mating surfaces that rotate relative to each other) are provided with wear-resistant coatings. Furthermore, the mating area of ​​the first arc-shaped end 102 and the second arc-shaped end 202 (i.e., the outer arc surface of the first arc-shaped end 102) is provided with a lubrication groove, which can further improve the wear resistance and deformation resistance, extend the service life of the hinge, and reduce the maintenance or replacement costs caused by structural failure.

[0029] Example 5

[0030] Please see Figure 1-5 Based on Embodiment 1, this embodiment further limits the structural strength of the mounting end. Reinforcing ribs are provided on the first mounting end 101 and the second mounting end 201 respectively. By providing reinforcing ribs on the first mounting end 101 and the second mounting end 201 and integrally forming them with the first mounting end 101 and the second mounting end 201 respectively, the bending strength of the mounting end can be improved and the local deformation during bolt tightening can be reduced.

[0031] The working process of this utility model is as follows: When using the movable hinge profile of the vehicle body, the first hinge profile 1 is first fixed to the fixed part of the vehicle body (such as the frame) through the first mounting hole 104 of the first mounting end 101; the second hinge profile 2 is fixed to the movable part of the vehicle body (such as the door) through the second mounting hole 204 of the second mounting end 201. When the movable part of the vehicle body (such as the door) needs to be opened or closed, the second hook-shaped end 203 of the second hinge profile 2 rotates relative to the first hook-shaped end 103 of the first hinge profile 1, and at the same time, the first arc-shaped end 102 cooperates with the second arc-shaped end 202 to realize the smooth opening and closing action of the movable part of the vehicle body.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
