[0041] The application discloses a door reinstallation self-positioning hinge structure and a vehicle.

[0042] Reference below Figures 1 to 4 The present invention describes a door reinstallation self-positioning hinge structure and a vehicle according to an embodiment of the present application.

[0043] like Figures 1 to 4 As shown, the vehicle door reinstallation self-positioning hinge structure 100 is used to connect the vehicle body and the vehicle door. The vehicle door reinstallation self-positioning hinge structure 100 includes a first connecting member 110, a second connecting member 120 and a positioning portion 130.

[0044] The first connecting member 110 is provided with a first connecting structure 111 for fixedly connecting with the vehicle body. The first connecting member 110 is fixedly connected with the vehicle body through the first connecting structure 111, which can increase the stability of the entire structure and improve the safety and reliability of the vehicle. The provision of the first connecting structure 111 can make the installation and removal of the first connecting member 110 simpler and more convenient, thereby facilitating the manufacture and maintenance of the vehicle. The fixed connection of the first connecting structure 111 can ensure the firm connection between the first connecting member 110 and the vehicle body, thereby improving the safety of the vehicle.

[0045] It should be noted that, in the embodiment of the present application, the first connecting member 110 structure may be a through hole, and in other embodiments, the first connecting member 110 structure may also be a threaded hole. Specifically, the present application does not limit this.

[0046] The second connecting member 120 is hinged to the first connecting member 110, and the second connecting member 120 has a first connecting surface 121 extending vertically, and the first connecting surface 121 is provided with a second connecting structure 122 for fixed connection with the vehicle door, so that the second connecting structure 122 can make the fixed connection between the second connecting member 120 and the vehicle door simpler and more convenient, thereby facilitating the manufacture and maintenance of the vehicle. The fixed connection of the second connecting structure 122 can ensure the firm connection between the second connecting member 120 and the vehicle door, thereby improving the safety of the vehicle.

[0047] In addition, since the second connecting member 120 is hinged to the first connecting member 110, the door and the body are hinged, allowing the door to be opened and closed in the horizontal direction, making it convenient for passengers to enter and leave the vehicle. The hinged connection method allows the door to better disperse the impact force during a collision and reduce the damage to passengers. Adapt to different angles: The hinged connection method allows the door to be opened and closed at different angles to adapt to passengers of different heights and different situations.

[0048] The positioning portion 130 is arranged on the second connecting member 120 and is arranged to protrude from the first connecting surface 121. The positioning portion 130 is installed in coordination with the positioning hole arranged in the vehicle door to ensure the accurate positioning of the vehicle door reinstallation position, thereby achieving precise assembly of the vehicle door and the vehicle body, thereby ensuring the sealing performance between the vehicle door and the vehicle body and reducing problems such as noise and air leakage.

[0049] According to the vehicle door reinstallation self-positioning hinge structure 100 of the present application, by providing a positioning portion 130 on the second connecting member 120, and making the positioning portion 130 cooperate with the positioning hole provided on the vehicle door for installation, the accuracy of the vehicle door reinstallation position is ensured, and the precise assembly of the vehicle door and the vehicle body is achieved, so as to ensure the sealing performance between the vehicle door and the vehicle body, and reduce the problems of noise and air leakage. In addition, the assembly efficiency and assembly quality are improved, and the vehicle body is ensured to have a good appearance. In addition, the vehicle door reinstallation self-positioning hinge structure 100 only slightly increases the weight while meeting the requirements of precise reinstallation positioning, which is in line with the design concept of lightweight vehicle body, and has low cost and high degree of process realization.

[0050] In one embodiment, the positioning part 130 is movably installed on the second connecting member 120 in the transverse direction so that the position of the positioning part 130 is adjustable in the transverse direction. In this way, by adjusting the position of the positioning part 130, the door can be accurately assembled with the body during initial installation to ensure the sealing performance between the door and the body, and to reduce noise and air leakage. Then the position of the positioning part 130 is locked, the door and the body are disassembled and the corresponding accessories are assembled. After the assembly is completed, the positioning hole of the door is re-installed with the positioning part 130 to achieve rapid and accurate positioning of the door, so that the gap between the reassembled door and the body can be adjusted to the state before the door is disassembled. Then the door is connected and fixed by the second connecting structure 122, which improves the assembly efficiency and assembly quality and ensures that the body has a good appearance. In addition, the door reinstallation self-positioning hinge structure 100 only slightly increases the weight while meeting the reinstallation precision positioning, which conforms to the design concept of lightweight body, and has low cost and high degree of process realization.

[0051] Refer to 1 and Figure 4 In one embodiment, the first connecting surface 121 is provided with a strip hole 123, and the strip hole 123 is extended in the horizontal direction. The positioning part 130 is installed in the strip hole 123 in a sliding manner in the horizontal direction. In this way, its position can be adjusted according to actual needs, which is convenient for installation and debugging. Through the cooperation of the strip hole 123 and the positioning part 130, the position of the vehicle body and the vehicle door can be accurately controlled, the installation accuracy can be improved, and the error can be reduced. The positioning part 130 and the strip hole 123 are installed in a sliding manner, which can increase the stability of the door adjustment. By accurately controlling the position of the door, the sealing performance between the door and the vehicle body can be better maintained, and the problems such as noise and air leakage can be reduced. Through the installation of the positioning part 130 and the strip hole 123, the assembly process of the door can be simplified and the production efficiency can be improved. The design of the strip hole 123 can adapt to the positioning parts 130 of different sizes and shapes, and has good adaptability.

[0052] Reference Figure 2 and Figure 3 In one embodiment, the positioning portion 130 has a limiting section 131 and a sliding section 132 which are connected in sequence. A first step surface a is formed between the limiting section 131 and the sliding section 132 and is arranged toward the first connecting surface 121. The sliding section 132 is slidably installed in the strip hole 123. The first step surface a abuts against the periphery of the strip hole 123. In this way, the design of the limiting section 131 and the sliding section 132 can increase the stability of the positioning portion 130, making the positioning portion 130 more stable during installation and use. The design of the first step surface a can make the fit between the positioning portion 130 and the strip hole 123 tighter, thereby improving the installation accuracy. In addition, it can make the installation and disassembly of the positioning portion 130 more convenient, thereby simplifying the assembly process. The design of the first step surface a can better maintain the sealing performance between the vehicle door and the vehicle body, thereby enhancing the sealing performance of the vehicle.

[0053] Reference Figure 4 In one embodiment, the strip hole 123 has two sliding planes 1231 that are opposite to each other and spaced apart in the vertical direction, and the positioning portion 130 has two matching planes that are opposite to the two sliding planes 1231, and each matching plane is slidably attached to the corresponding sliding plane 1231. In this way, the design of the two sliding planes 1231 can increase the stability between the strip hole 123 and the positioning portion 130, making the entire structure more stable. Through the cooperation between the two oppositely arranged sliding planes 1231 and the matching planes, the cooperation between the positioning portion 130 and the strip hole 123 can be made tighter. In addition, the positioning portion 130 can be prevented from rotating relative to the strip hole 123 during the adjustment process, thereby improving the installation and adjustment accuracy. The design of the sliding plane 1231 can make the installation and disassembly of the positioning portion 130 more convenient, thereby simplifying the assembly process. Through the cooperation between the sliding plane 1231 and the matching plane, the positioning portion 130 can be made more durable during use, thereby increasing the service life. By designing that each matching plane is slidably attached to the corresponding sliding plane 1231, the sealing performance between the vehicle door and the vehicle body can be better maintained, thereby enhancing the sealing performance of the vehicle.

[0054] In one embodiment, the door reinstallation self-positioning hinge structure 100 also includes a locking member, which is connected to the positioning portion 130. The locking member can limit the sliding of the positioning portion 130, so that the position of the positioning portion 130 can be fixed after the position adjustment, which is convenient for accurate positioning of the door. In addition, the locking member can prevent the positioning portion 130 from sliding accidentally, thereby enhancing the stability of the entire structure. The design of the locking member can prevent the positioning portion 130 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, the wear of the positioning portion 130 during use can be reduced, thereby increasing its service life.

[0055] Reference Figure 2 and Figure 3In one embodiment, the positioning portion 130 further includes a locking stud 134, which is connected to the sliding section 132, and a portion of the locking stud 134 is arranged to extend out of the bar-shaped hole 123. The locking member includes a locking nut, which is sleeved on the locking stud 134 and threadedly connected to the locking stud 134. In this way, the design of the locking nut can be conveniently connected to the locking stud 134, thereby simplifying the installation process. Through the threaded connection, it can be ensured that the connection between the locking member and the locking stud 134 is firm and durable, thereby improving the service life of the entire structure. Since the locking stud 134 is partially arranged to extend out of the bar-shaped hole 123, when the locking nut is tightened, the end face of the locking nut can abut against the second connection surface of the second connecting member 120 that is away from the first connection surface 121, thereby achieving locking and limiting of the positioning portion 130, preventing the positioning portion 130 from moving, and improving the accuracy of positioning. When maintenance or overhaul is required, the position of the positioning portion 130 can be adjusted by tightening or loosening the locking nut, which is convenient and quick.

[0056] Reference Figure 4 In one embodiment, the second connection structure 122 includes two first mounting holes 124 arranged along a vertical interval, and the strip hole 123 is located on one side of the line connecting the two first mounting holes 124. In this way, the design of the two first mounting holes 124 can increase the stability of the second connection structure 122, making it more stable and reliable during use. In addition, it is convenient to install and disassemble the door and the second connecting member 120, thereby simplifying the installation process. By arranging the strip hole 123 on one side of the line connecting the two first mounting holes 124, it is convenient to adjust the position of the door body according to the specific structure of the vehicle body, ensure the precise assembly of the vehicle body and the door, and better maintain the sealing performance between the door and the vehicle body, thereby enhancing the sealing performance of the vehicle. Through the design of the two first mounting holes 124.

[0057] The embodiment of the present application further provides a vehicle, comprising the door reinstallation self-positioning hinge structure 100 as described above.

[0058] According to the vehicle of the present application, by setting the positioning part 130 on the second connecting member 120, and making the positioning part 130 cooperate with the positioning hole set in the door to ensure the accuracy of the door reinstallation position, and realize the precise assembly of the door and the body, so as to ensure the sealing performance between the door and the body, and reduce the problems of noise and air leakage. In addition, the assembly efficiency and assembly quality are improved, and the body is guaranteed to have a good appearance. In addition, the door reinstallation self-positioning hinge structure 100 only slightly increases the weight while meeting the precise positioning of the reinstallation, which is in line with the lightweight design concept of the body, and has low cost and high degree of process realization.

[0059] In one embodiment, the vehicle further includes a vehicle body and vehicle doors.

[0060] The vehicle body is connected to the first connection structure 111, so that the connection between the door 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 door 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 door reinstallation self-positioning hinge structure 100 and the vehicle body can be increased, reducing vibration and noise during vehicle driving.

[0061] The vehicle door is connected to the second connection structure 122, and the positioning hole of the vehicle door is suitable for being installed in cooperation with the positioning portion 130. By connecting the vehicle door to the second connection structure 122, the position of the vehicle door reinstallation can be made more accurate, thereby improving the installation accuracy.

[0062] The design of the second connection structure 122 can increase the stability of the door, making the door more reliable during use, making the position of the door more secure, and improving the safety of the vehicle. By matching the positioning hole of the door with the positioning part 130, the door can be quickly and accurately positioned for reinstallation, and the sealing performance between the door and the vehicle body can be better maintained, thereby enhancing the sealing performance of the vehicle. By matching the positioning hole of the door with the positioning part 130, the door can be easily installed and removed, thereby simplifying the installation process.

[0063] In one embodiment, the second connection structure 122 includes two first mounting holes 124 arranged at intervals along the vertical direction. In this way, by connecting the vehicle door to the two first mounting holes 124, the stability of the vehicle door can be increased, making the vehicle door more reliable during use. The vehicle door is connected to the two first mounting holes 124 by two connecting bolts. The design of the connecting bolts can enhance the rigidity of the vehicle body and improve the bearing capacity and service life of the vehicle. The design of the connecting bolts can make the position of the vehicle door 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. Among them, the outer diameter of each connecting bolt is smaller than the aperture of the corresponding first mounting hole 124. 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 vehicle door can be adjusted according to the actual situation, thereby better maintaining the sealing performance between the vehicle door 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 the actual situation to adapt to different installation requirements.
