[0026] Please see Figures 1 to 3This application provides an upper control arm auxiliary installation fixture 100 for assisting the installation of an upper control arm 200 onto a body assembly 300. The upper control arm auxiliary installation fixture 100 includes a main board 10 and at least one positioning block 20. The main board 10 is detachably connected to the body assembly 300. One end of the positioning block 20 is connected to the main board 10, and the other end has a support surface 21 for abutting against the upper control arm 200. By providing a support surface 21 on the positioning block 20, and by having the support surface 21 abut against the upper control arm 200, the contact area between the upper control arm auxiliary installation fixture 100 and the upper control arm 200 is increased, thereby improving the support effect of the upper control arm auxiliary installation fixture 100 on the upper control arm 200. This helps maintain the upper control arm 200 in a predetermined position during installation, thus improving the height consistency of the upper control arm after installation.

[0027] Alternatively, in one embodiment, as Figure 2 As shown, the upper swing arm 200 includes two connected support arms 210. Two positioning blocks 20 are configured, and the support surface 21 on each positioning block 20 is used to support one support arm 210. By setting two positioning blocks 20, the support surfaces 21 on the two positioning blocks 20 respectively support the two support arms 210 of the upper swing arm 200, making the force on the upper swing arm 200 more even, thereby further improving the support effect of the upper swing arm auxiliary installation fixture 100 on the upper swing arm 200. However, this is not the only limitation; in other embodiments, the number of positioning blocks 20 can also be three or four, which can be set according to actual needs.

[0028] Furthermore, along the length of the motherboard 10, two positioning blocks 20 are respectively connected to both ends of the motherboard 10. This increases the distance between the two positioning blocks 20, which in turn increases the distance between the two support surfaces 21, and also increases the distance between the two force-bearing positions on the upper swing arm 200, thereby helping to avoid force concentration on the upper swing arm 200.

[0029] Optionally, the two support surfaces 21 are symmetrically arranged at the two force-bearing positions formed on the upper swing arm 200. The dimensions of the two positioning blocks 20 may be the same or different.

[0030] The shape of the support surface 21 is adapted to at least a portion of the surface shape of the upper swing arm 200 for contact with the upper swing arm 200. Contact between the support surface 21 and the upper swing arm 200 improves the reliability of the upper swing arm auxiliary mounting fixture 100 in supporting the upper swing arm 200. Optionally, the support surface 21 can be configured as a slope, a plane, or a curved surface, depending on the shape of the upper swing arm 200.

[0031] In one embodiment, such as Figure 2As shown, the positioning block 20 includes a connecting section 22 and a supporting section 23 arranged at an angle. The connecting section 22 is attached to and connected to the motherboard 10, and the supporting surface 21 is located at the end of the supporting section 23 away from the connecting section 22. By setting the connecting section 22, the contact area between the positioning block 20 and the motherboard 10 can be increased. By setting the supporting section 23, it is convenient to process the supporting surface 21.

[0032] The connecting segment 22 and the supporting segment 23 can be an integral structure or separate components that are fixedly connected. The included angle between the connecting segment 22 and the supporting segment 23 can be set according to the support requirements for the upper swing arm 200. For example, the included angle between the connecting segment 22 and the supporting segment 23 can be 90°. That is, the connecting segment 22 and the supporting segment 23 are perpendicular to each other.

[0033] Furthermore, the connecting segment 22 is detachably connected to the motherboard 10.

[0034] like Figure 2 As shown, the mainboard 10 is provided with a positioning pin 11, and the body assembly 300 is provided with a positioning hole. The positioning pin 11 is used to position and cooperate with the positioning hole. In this way, it is convenient to quickly install and position the upper swing arm auxiliary installation fixture 100 onto the body assembly 300, and after the upper swing arm 200 is installed, it is convenient to quickly remove the upper swing arm auxiliary installation fixture 100 from the body assembly 300.

[0035] Optionally, the number of positioning pins 11 is configured to be multiple, and the multiple positioning pins 11 are distributed at intervals on the motherboard 10.

[0036] Please see Figure 1 The upper swing arm auxiliary installation fixture 100 also includes a handle 30, which is mounted on the main board 10. The handle 30 is for the user to hold, thereby facilitating the user to quickly pick up the upper swing arm auxiliary installation fixture 100.

[0037] like Figure 1 and Figure 2 As shown, the mainboard 10 has a contoured surface 14, the shape of which is adapted to at least a portion of the surface shape of the body assembly 300 for bonding with the body assembly 300.

[0038] In one embodiment, the motherboard 10 includes a main body 12 and a mounting portion 13 connected to the side of the main body 12. A handle 30 is mounted on the main body 12, and a positioning block 20 is connected to the mounting portion 13. In this way, the mounting positions of the handle 30 and the positioning block 20 on the main body 12 can be reasonably arranged, thereby avoiding interference between the user and the positioning block 20 when using the handle 30.

[0039] For example, in one embodiment, the number of mounting parts 13 is configured to be two, and the two mounting parts 13 are connected to the same side of the main body 12 and are configured as an integral structure with the main body 12. Each mounting part 13 is connected to a corresponding positioning block 20.

[0040] The positioning block 20 and the handle 30 are detachably connected to the main board 10.

[0041] Specifically, the connecting section 22 of each positioning block 20 is bolted to a mounting part 13. The handle 30 is bolted to the main body 12. The positioning pin 11 is threaded to the main body 12.

[0042] Optionally, the upper control arm auxiliary mounting fixture 100 also includes a support block 40, which is detachably connected to the side of the main board 10 and used to fit the body assembly 300. The support block 40 is used to increase the contact area between the upper control arm auxiliary mounting fixture 100 and the body assembly 300. Specifically, the support block 40 is bolted to the main board 10.

[0043] In one embodiment, the upper swing arm auxiliary mounting fixture 100 is made of aluminum and steel. The upper swing arm auxiliary mounting fixture 100 has a maximum height of 172.43 mm, a maximum length of 237.8 mm, and a maximum thickness of 31 mm. The two positioning blocks 20 have different dimensions: one positioning block 20 has a maximum length of 50 mm, a maximum height of 157.43 mm, and a maximum width of 30 mm; the other positioning block 20 has a maximum length of 50 mm, a maximum height of 115.45 mm, and a maximum width of 20 mm. The main board 10 has a maximum length of 170 mm, a maximum height of 20 mm, and a maximum width of 95 mm.

[0044] The process of using the upper control arm auxiliary installation fixture 100 provided in this application to assist in the installation of the upper control arm 200 to the body assembly 300 is as follows:

[0045] First, align the upper control arm auxiliary mounting fixture 100 with the positioning pin 11 and make the contour surface 14 fit against the body assembly 300. Next, pre-install the upper control arm 200 by bolting it to the body assembly 300. Then, make the support surface 21 fit against the corresponding position of the upper control arm 200, and the upper control arm auxiliary mounting fixture 100 provides support for the upper control arm 200. Further, tighten the bolts to fix the upper control arm 200 to the body assembly 300. Finally, pull the positioning pin 11 out of the positioning hole and remove the upper control arm auxiliary mounting fixture 100 from the body assembly 300.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the scope of protection of this application. Therefore, the patent protection scope of this application should be determined by the appended claims.
