It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0018] The fixing fixture according to the present invention is described below with reference to the accompanying drawings.

[0019] like Figure 1 As shown, in this embodiment, a fixing fixture is proposed for connecting the car door and the car body. The fixing fixture includes a connecting component and an mounting component. The connecting component includes a bushing 11 and a connecting pin 12 sleeved in the bushing 11. The bushing 11 and the connecting pin 12 can rotate relative to each other. The mounting component includes a first mounting plate 21 and a second mounting plate 22. The first end of the first mounting plate 21 is detachably connected to the car door, and the second end of the first mounting plate 21 is connected to the outer periphery of the bushing 11. The first end of the second mounting plate 22 is detachably connected to the car body, and the second end of the second mounting plate 22 is connected to the connecting pin 12.

[0020] In this embodiment, the fixing fixture is provided with a first mounting plate 21 for connecting the car door and a second mounting plate 22 for connecting the car body. The bushing 11 connected to the first mounting plate 21 and the connecting pin 12 connected to the second mounting plate 22 can rotate relative to each other. This ensures that the car door can be installed on the car body through the fixing fixture and that the car door can open and close stably relative to the car body. This solves the problem of poor connection between the car body and the car door and poor assembly stability in the prior art.

[0021] like Figure 2 As shown, in this embodiment, the first mounting plate 21 includes a mounting portion 211 and a curved portion 212. The mounting portion 211 is detachably connected to the vehicle door, and the curved portion 212 is integrally connected to the mounting portion 211 and extends in a direction away from the vehicle door. The integrally connected mounting portion 211 and curved portion 212 have high structural strength. A bushing 11 is connected to the inner wall of the curved portion 212. The bushing 11 has a mounting hole for the connecting pin 12 to be inserted, ensuring that the bushing 11 can be easily installed on the connecting pin 12, making disassembly and assembly convenient. The curved portion 212 extends in a direction away from the vehicle door, and the inner wall of the curved portion 212 has sufficient mounting area for the bushing 11 to be installed, ensuring that the bushing 11 can be stably installed on the first mounting plate 21.

[0022] like Figure 3 As shown, in this embodiment, the fixing fixture also includes locking fasteners. The second mounting plate 22 has multiple locking holes 221, and the number of locking fasteners is multiple, each corresponding to one of the locking holes 221. The locking fasteners pass through the locking holes 221 to detachably install the second mounting plate 22 onto the vehicle body, facilitating easy installation and removal with good stability. In this application, the second mounting plate 22 has two locking holes 221, ensuring that the second mounting plate 22 can be securely installed on the vehicle body. The number of locking holes 221 can be adjusted according to actual needs. The locking fasteners can be bolts from the prior art, with the locking holes 221 and the locking fasteners threadedly engaging to stably lock the second mounting plate 22 onto the vehicle body.

[0023] like Figure 3 As shown, in this embodiment, the second mounting plate 22 has a clearance opening 222 for avoiding interference between the second mounting plate 22 and external components on the vehicle body. Multiple locking holes 221 are spaced apart along the height direction on both sides of the clearance opening 222. The height direction is the up-down direction shown in the figure. The two locking holes 221 in this application are respectively arranged on the upper and lower sides of the clearance opening 222. By using a locking fastener passing through the locking hole 221, the second mounting plate 22 can be stably installed on the vehicle body.

[0024] like Figure 3As shown, in this embodiment, the second mounting plate 22 has multiple isolation protrusions 223 on the side facing the vehicle body, and each isolation protrusion 223 corresponds to a locking hole 221. In this application, the isolation protrusions 223 create a gap between the side of the second mounting plate 22 facing the vehicle body and the door. This ensures sufficient electrophoresis treatment of the vehicle body and a better processing effect during electrophoresis. Similarly, to ensure the electrophoresis treatment effect on the door, the first mounting plate 21 can also have multiple locking holes 221. Multiple locking fasteners are provided, each corresponding to a locking hole 221. These fasteners can lock the first mounting plate 21 onto the door. Furthermore, the first mounting plate 21 can also have multiple isolation protrusions 223, each corresponding to a locking hole 221, ensuring sufficient electrophoresis treatment of the door.

[0025] like Figure 3 As shown, in this embodiment, the fixing fixture also includes a limiting member 3 connected to the second mounting plate 22. The limiting member 3 extends away from the vehicle body and is spaced apart from the curved portion 212. The bushing 11 is located in the space formed by the curved portion 212 and the limiting member 3, and a clearance is left between the limiting member 3 and the outer peripheral wall of the bushing 11. During the relative rotation of the bushing 11 and the connecting pin 12, the first mounting plate 21 and the second mounting plate 22 can move relative to each other. In this application, the limiting member 3 is provided on the second mounting plate 22. When the second mounting plate 22 rotates relative to the first mounting plate 21 to a preset angle, the limiting member 3 can abut against the first mounting plate 21 to limit the opening angle of the second mounting plate 22 relative to the first mounting plate 21, thus preventing the door from opening too far relative to the vehicle body. It should be noted that the preset angle can be set according to actual needs.

[0026] like Figure 1 and Figure 3 As shown, in this embodiment, the limiting member 3 is a plate-shaped structure and is set with a corresponding bushing 11 to ensure that the limiting member 3 can accurately abut against the curved part 212 when the opening and closing angle is at its maximum during the movement of the second mounting plate 22. This avoids the limiting effect of the limiting member 3 being affected by the weight reduction notch 213 on the first mounting plate 21, which would prevent the limiting member 3 from being unable to limit the opening and closing angle of the door relative to the body, thus affecting the transportation and processing of the body and door.

[0027] like Figure 3As shown, in this embodiment, the connecting pin 12 includes an integrally connected body portion 121 and a protrusion portion 122. The diameter of the protrusion portion 122 is larger than the diameter of the body portion 121. The bushing 11 is sleeved on the outer peripheral wall of the body portion 121 to prevent the bushing 11 from slipping off the outer peripheral wall of the body portion 121. The protrusion portion 122 is used to connect with the second mounting plate 22. Specifically, the second mounting plate 22 can be installed on the second mounting plate 22 by welding. Similarly, the first mounting plate 21 can be installed on the bushing 11 by welding, resulting in good installation stability.

[0028] like Figure 2 As shown, in this embodiment, a weight-reducing notch 213 is also provided on the first mounting plate 21 to ensure stable installation of the first mounting plate 21 and the door while reducing the overall weight of the first mounting plate 21. The weight-reducing notch 213 is located at the bent portion 212 that is not connected to the bushing 11, to avoid affecting the installation stability of the first mounting plate 21 and the bushing 11. Furthermore, the weight-reducing notch 213 extends towards the mounting plate portion.

[0029] like Figure 4 As shown, in this embodiment, the fixing fixture also includes an elastic component 4 connected between the front of the door and the vehicle body. The elastic component 4 includes an elastic element 41 and a snap-fit ​​element 42. The two ends of the elastic element 41 are respectively connected to the front of the door and the vehicle body. One end of the snap-fit ​​element 42 is connected to the elastic element 41, and the other end of the snap-fit ​​element 42 away from the elastic element 41 can abut against the vehicle body.

[0030] It should be noted that by adding an elastic element 41 and connecting its two ends to the front ends of the vehicle body and the door respectively, this application effectively prevents the door from opening at an excessively large angle relative to the vehicle body, thus avoiding interference with the normal transportation and processing of the vehicle body and door. Furthermore, the latching element 42 is connected to the elastic element 41 and is also located between the vehicle body and the door. The latching element 42 abuts against the vehicle body, supporting the door and preventing it from closing and shaking. The elastic element 41 can be a spring as used in the prior art.
