[0040] The present application discloses a hood reinstallation self-positioning hinge structure and a vehicle.

[0041] Reference below Figures 1 to 4 The present invention describes a hood reinstallation self-positioning hinge structure and a vehicle according to an embodiment of the present application.

[0042] like Figure 1 and Figure 2 As shown, the cover reinstallation self-positioning hinge structure 100 includes a fixed part 110, a movable part 120 and a positioning assembly.

[0043] The fixing part 110 is provided with a first connection structure 111 for fixing the fixing part 110 to the vehicle body.

The fixed connection of the first connection structure 111 can facilitate installation and removal, thereby simplifying the installation process.

[0044] The movable part 120 is hinged to the fixed part 110, and the movable part 120 is provided with a second connection structure 121 for fixed connection with the hood. Thus, the provision of the second connection structure 121 can make the fixed connection between the movable part 120 and the hood simpler and more convenient, thereby facilitating the manufacture and maintenance of the vehicle. The fixed connection of the second connection structure 121 can ensure the firm connection between the movable part 120 and the hood, thereby improving the safety of the vehicle.

[0045] The positioning assembly includes a positioning portion 131 and a matching portion matched with the positioning portion 131. One of the positioning portion 131 and the matching portion is arranged on the movable portion 120, and the other is used to be arranged on the hood. In this way, through the cooperation of the positioning portion 131 and the matching portion, accurate positioning between the movable portion 120 and the hood can be achieved, ensuring that when the hood is reinstalled, the relative position of the hood and the vehicle body is accurately transferred. The cooperation between the positioning portion 131 and the matching portion can enhance the stability between the movable portion 120 and the hood, making them more reliable during use. The cooperation between the positioning portion 131 and the matching portion can enhance the strength and intensity of the entire structure, and improve the carrying capacity and service life of the vehicle. Through the cooperation between the positioning portion 131 and the matching portion, installation and disassembly can be conveniently performed, thereby simplifying the installation process and improving assembly efficiency and assembly quality.

[0046] According to the hood reinstallation self-positioning hinge structure 100 of the present application, the precise positioning between the movable part 120 and the hood can be achieved through the cooperation of the positioning part 131 and the matching part, ensuring that the relative position of the hood and the vehicle body is accurate when the hood is reinstalled. The cooperation of the positioning part 131 and the matching part can enhance the stability between the movable part 120 and the hood, making them more reliable during use. The cooperation of the positioning part 131 and the matching part can enhance the strength and strength of the entire structure and improve the carrying capacity and service life of the vehicle. Through the cooperation of the positioning part 131 and the matching part, installation and disassembly can be conveniently performed, thereby simplifying the installation process and improving assembly efficiency and assembly quality. In addition, the hood reinstallation self-positioning hinge structure 100 of the present application solves the problem of precise positioning during the hood reinstallation process through structural optimization design without sacrificing the exquisiteness of the entire vehicle, and while meeting the precise positioning of the reinstallation, the weight is only slightly increased, which is in line with the lightweight design concept of the vehicle body, can reduce costs, and achieve a high degree of process realization.

[0047] Reference Figures 2 to 4 In one embodiment, the positioning portion 131 includes a positioning pin 1311, and the matching portion includes a positioning hole. Thus, the hood can be accurately positioned by the matching of the positioning pin 1311 and the positioning hole, ensuring that the hood is accurately positioned relative to the vehicle body when it is reinstalled. The matching of the positioning pin 1311 and the positioning hole can facilitate installation and removal, thereby simplifying the installation process. In addition, the processing technology can be simplified, saving costs.

[0048] It should be noted that in other embodiments, in one embodiment, the positioning portion 131 may further include a positioning boss, and the matching portion may further include a positioning groove, etc. Specifically, the present application does not limit this.

[0049] Reference Figure 2 In one embodiment, the first surface a of the movable portion 120 that is arranged upward is provided with an adjustment hole 122, and the positioning pin 1311 is movably installed in the adjustment hole 122, so that the position of the positioning pin 1311 in the first surface a is adjustable. In this way, since the position of the positioning pin 1311 is adjustable, its position can be adjusted according to actual needs, which is convenient for installation and debugging. The positioning pin 1311 is installed in cooperation with the positioning hole set in the hood, so that the position of the hood can be accurately controlled, the installation accuracy can be improved, and the error of the hood reinstallation position can be reduced. The positioning pin 1311 is installed in cooperation with the hood through the positioning hole, which can increase the stability of the hood and improve the stability and safety of the vehicle driving. By accurately controlling the reinstallation position of the hood, the assembly accuracy between the hood and the vehicle body can be better maintained, and the assembly volume and the aesthetics of the vehicle body can be improved. By cooperating with the positioning pin 1311 and the positioning hole, the assembly process of the hood can be simplified and the production efficiency can be improved.

[0050] Reference Figure 1 and Figure 4 In one embodiment, the positioning pin 1311 has a limiting section 13111 and an adjusting section 13112 which are connected in sequence. A first step surface b facing the first surface a is formed between the limiting section 13111 and the adjusting section 13112. The first step surface b abuts against the periphery of the adjusting hole 122. In this way, the design of the limiting section 13111 and the adjusting section 13112 can increase the stability of the positioning pin 1311, making the positioning pin 1311 more stable during installation and use. The design of the first step surface b can make the fit between the positioning pin 1311 and the adjusting hole 122 tighter, thereby improving the installation accuracy. In addition, it can make the installation and removal of the positioning pin 1311 more convenient, thereby simplifying the assembly process. The design of the first step surface b can better maintain the position of the hood relative to the vehicle body and achieve accurate positioning of the hood.

[0051] In addition, the adjustment section 13112 is in the adjustment hole 122, and the outer diameter of the adjustment section 13112 is smaller than the aperture of the adjustment hole 122, so that continuous adjustment can be achieved, that is, the position or angle of the adjustment section 13112 can be continuously changed within a certain range to meet different work requirements. Since the outer diameter of the adjustment section 13112 is smaller than the aperture of the adjustment hole 122, precise adjustment of the positioning position can be achieved. Through the design of the adjustment section 13112, the position of the positioning pin 1311 can be easily adjusted, thereby simplifying the installation process.

[0052] In one embodiment, the adjustment section 13112 is partially extended out of the adjustment hole 122, and the positioning assembly further includes a locking member 133, which is connected to the portion of the adjustment section 13112 extending out of the adjustment hole 122. The locking member 133 can limit the movement of the positioning pin 1311 on the first surface a, so that the position of the positioning pin 1311 is fixed after the position is adjusted, which is convenient for accurate positioning of the cover. In addition, the locking member 133 can prevent the positioning pin 1311 from accidentally sliding, thereby enhancing the stability of the entire structure. The design of the locking member 133 can prevent the positioning pin 1311 from sliding during use, thereby reducing the maintenance and repair work caused thereby and improving work efficiency. Through the limiting effect of the locking member 133, the wear of the positioning pin 1311 during use can be reduced, thereby increasing its service life.

[0053] Reference Figures 2 to 4 In one embodiment, the outer wall of the adjustment section 13112 is provided with an external thread, and the locking member 133 includes a locking nut 1331, which is mounted on the adjustment section 13112 and is threadedly connected to the adjustment section 13112. In this way, the design of the locking nut 1331 can be conveniently connected to the adjustment section 13112, thereby simplifying the installation process. Through the threaded connection, it can be ensured that the connection between the locking member 133 and the adjustment section 13112 is firm and durable, thereby improving the service life of the entire structure. Since the adjustment section 13112 is partially extended out of the adjustment hole 122, when the locking nut 1331 is tightened, the end face of the locking nut 1331 can abut against the second surface c of the movable part 120 that is set downward, thereby achieving locking and limiting of the positioning pin 1311, preventing the positioning pin 1311 from moving, and improving the positioning accuracy. When maintenance or overhaul is required, the position of the positioning pin 1311 can be adjusted by tightening or loosening the locking nut 1331, which is convenient and quick.

[0054] Reference Figures 1 to 4In one embodiment, a groove d is provided on the first surface a, and the adjustment hole 122 is located at the bottom of the groove d. In this way, the design of the groove d can reduce the fitting area between the cover and the first surface a, thereby reducing friction and wear during the assembly process, thereby improving assembly efficiency, reducing errors during the assembly process, and improving product accuracy and stability.

[0055] Reference Figure 1 and Figure 2 In one embodiment, the second connection structure 121 includes two first mounting holes 1211 spaced apart in the front-to-back direction. The design of the two first mounting holes 1211 can enhance the strength and intensity of the entire structure, making the connection between the movable part 120 and the hood more secure, improving the safety of the vehicle, and also improving the vehicle's carrying capacity and service life. The adjustment hole 122 is located on the line connecting the two first mounting holes 1211. In this way, the hood can be positioned while making the hood reinstallation self-positioning hinge structure 100 compact. Through the design of the two first mounting holes 1211, the stability between the movable part 120 and the hood can be enhanced, making the connection between the movable part 120 and the hood more secure.

[0056] The embodiment of the present application further provides a vehicle, comprising the hood reinstallation self-positioning hinge structure 100 as described above, a vehicle body and a hood.

[0057] The vehicle body is connected to the first connection structure 111, so that the connection between the hood reinstallation self-positioning hinge structure 100 and the vehicle body can be made more stable, thereby improving the driving stability and safety of the vehicle. By connecting the vehicle body to the first connection structure 111, the hood reinstallation self-positioning hinge structure 100 and the vehicle body can be easily installed and disassembled, thereby simplifying the assembly process. By connecting the vehicle body to the first connection structure 111, the vibration resistance of the hood reinstallation self-positioning hinge structure 100 and the vehicle body can be increased, reducing vibration and noise during vehicle driving.

[0058] The hood is connected to the second connection structure 121, so that the position of the hood can be made more accurate and the installation accuracy can be improved. The design of the second connection structure 121 can increase the stability of the hood, making the hood more reliable during use, and can make the position of the hood more secure, thereby improving the safety of the vehicle. By matching the positioning holes of the hood with the positioning pins 1311 for installation, the hood can be quickly and accurately positioned during installation, and the sealing performance between the hood and the vehicle body can be better maintained, thereby enhancing the sealing performance of the vehicle. By matching the positioning holes of the hood with the positioning pins 1311 for installation, the hood can be easily installed and removed, thereby simplifying the installation process.

[0059] According to the vehicle of the present application, through the cooperation of the positioning part 131 and the matching part, the precise positioning between the movable part 120 and the hood can be achieved, ensuring that the relative position of the hood and the vehicle body is accurate when the hood is reinstalled. The cooperation of the positioning part 131 and the matching part can enhance the stability between the movable part 120 and the hood, making them more reliable during use. The cooperation of the positioning part 131 and the matching part can enhance the strength and intensity of the entire structure and improve the carrying capacity and service life of the vehicle. Through the cooperation of the positioning part 131 and the matching part, installation and disassembly can be conveniently performed, thereby simplifying the installation process and improving assembly efficiency and assembly quality. In addition, the hood reinstallation self-positioning hinge structure 100 of the present application solves the problem of precise positioning during the hood reinstallation process through structural optimization design without sacrificing the exquisiteness of the entire vehicle, and while meeting the precise positioning of the reinstallation, the weight is only slightly increased, which is in line with the lightweight design concept of the vehicle body, can reduce costs, and achieve a high degree of process realization.

[0060] In one embodiment, the second connection structure 121 includes two first mounting holes 1211 arranged at intervals along the front-back direction. In this way, by connecting the hood with the two first mounting holes 1211, the stability of the hood can be increased, making the hood more reliable during use. The hood is connected to the two first mounting holes 1211 by two connecting bolts. The design of the connecting bolts can enhance the rigidity of the vehicle body and improve the carrying capacity and service life of the vehicle. The design of the connecting bolts can make the position of the hood more secure and improve the safety of the vehicle. By connecting with the connecting bolts, installation and disassembly can be conveniently performed, thereby simplifying the installation process. The outer diameter of each connecting bolt is smaller than the aperture of the corresponding first mounting hole 1211. In this way, since the outer diameter of each connecting bolt is smaller than the aperture of the corresponding mounting hole, the position of the hood can be adjusted according to actual conditions, thereby better maintaining the sealing performance between the hood and the vehicle body, thereby enhancing the sealing of the vehicle. In addition, since the outer diameter of each connecting bolt is smaller than the aperture of the corresponding mounting hole, the connecting bolt can be selected according to actual conditions to adapt to different installation requirements.

[0061] In one embodiment, two self-positioning hinge structures 100 for reinstalling the cover are provided, and the two self-positioning hinge structures 100 for reinstalling the cover are arranged at intervals along the left and right directions. In this way, through the design of the two self-positioning hinge structures 100 for reinstalling the cover, the stability between the movable part 120 and the cover can be enhanced, so that the connection between the movable part 120 and the cover is more secure. The positioning parts 131 of the two self-positioning hinge structures 100 for reinstalling the cover each include a positioning pin 1311 provided on the movable part 120, and one of the two matching parts adapted to the two positioning pins 1311 is provided as a circular hole. When the positioning pin is installed in the circular hole, the gap between the inner wall surface of the circular hole and the outer wall surface of the corresponding positioning pin is small, and the other is provided as a long strip hole extending along the left and right directions. In this way, it is convenient to position and match the cover and the positioning pins 1311 of the two self-positioning hinge structures 100 for reinstalling the cover. In addition, this design increases the flexibility of installation, so that it can adapt to different work requirements.
