[0002] Figure 1 and 2 The connecting structure between the upper support of the sliding column and the mounting seat of the vehicle body in the prior art is shown. There are generally two ways to align it: A. Align manually during assembly. This method requires two additional operators, resulting in increased labor costs; the installation space between the upper support of the sliding column and the vehicle body is small and remote, with poor visibility and difficult operation, which can easily delay the production cycle. B. Install the sliding column on the vehicle body before assembling the chassis and the vehicle body. The above-mentioned connecting structure requires two additional operators and corresponding auxiliary lifting equipment, resulting in increased labor and equipment costs; the installation space between the upper support of the sliding column and the vehicle body is small and remote, with poor visibility and difficult operation, which can easily delay the production cycle.

[0031] The assembly method of the sliding column upper support and the vehicle body of the present invention will be further described below in conjunction with specific embodiments to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of the present invention.

[0032] Example 1

[0033] The assembly method of the sliding column upper support and the vehicle body in this embodiment specially designs a spiral guide structure 300, so that the sliding column upper support 100 and the vehicle body mounting seat 200 can be automatically aligned during the assembly process without the need for operator assistance in the alignment, which not only saves labor costs, but also avoids accidents of people being squeezed and injured by lifting equipment during the assembly process, and also significantly improves work efficiency.

[0034] like Figure 5-6As shown, the spiral guide structure 300 includes a triangular columnar structure 310 and a spiral triangular pyramid structure 320. The spiral triangular pyramid structure 320 is located above the triangular columnar structure 310 and the two are integrally formed. The guide structure can be made of non-metallic materials such as nylon or metal-non-metallic composite materials. Each of the three edges of the triangular columnar structure 310 is provided with a vertically extending ridge 311, and a clamping structure 312 is provided on the outer surface between adjacent ridges 311. Three spiral ridges 321 extending downward from the vertex are distributed on the outer surface of the spiral triangular pyramid structure 320, and the bottom end of the ridge 321 is connected to the top end of the ridge 311.

[0035] like Figure 7 As shown, the sliding column upper support includes an upper support body 103, a first triangular center hole 101 is provided on the sliding column upper support body 103, and a fastener 102 is provided on the periphery of the sliding column upper support body 103, and the fastener 102 is arranged in a one-to-one correspondence with the vertex angle of the first triangular center hole 101. The fastener 102 can be selected from a stud, a nut or a screw.

[0036] like Figure 6 As shown, the vehicle body mounting seat 200 includes a mounting seat body 203, a ring boss 204 and three mounting holes 202 are arranged in the middle of the mounting seat body 203, a second triangular middle hole 201 is arranged in the center of the ring boss 204, and the mounting holes 202 correspond to the apex angles of the second triangular middle hole 201 one by one.

[0037] When the guide structure 300 and the sliding column upper support 100 are assembled, the height of the triangular column structure 310 of the guide device 300 should be greater than the height of the fastener 102 .

[0038] like Figure 3-4As shown, when the chassis is assembled, the clamping structure 312 of the guide device 300 is first clamped into the triangular center hole 101 of the upper support 100 of the sliding column. Then the suspension assembly is lifted upward (or the vehicle body assembly is dropped), and when the head of the spiral triangular pyramid structure 320 of the guide device 300 is inserted into the triangular center hole 201 of the vehicle body mounting seat 200 and the convex column 321 of the spiral triangular pyramid 320 contacts the edge of the triangular center hole 201, the contact force of the three contact points generates a rotation torque on the spiral triangular pyramid 320 in the direction of the axis of the guide device 300. During the lifting process (or the vehicle body falling), the guide device 300 rotates around its own axis under the action of the rotation torque. When the triangular column structure 310 of the guide device 300 just contacts the triangular center hole 201 on the vehicle body mounting seat 200, the convex ridge 311 of the triangular column structure 310 of the guide device 300 and the three angles of the triangular center hole 201 of the vehicle body mounting seat 200 are consistent. At this time, the three fasteners 102 on the upper support 100 of the sliding column are respectively coaxial with the three mounting holes 202 on the vehicle body mounting seat 200, that is, the guiding is completed at this time. Continue to lift further (or the vehicle body falls), the three fasteners 102 on the upper support 100 of the sliding column are respectively inserted into the three mounting holes 202 on the vehicle body mounting seat 200, and when the upper support 100 of the sliding column and the vehicle body mounting seat 200 are fitted, the three fasteners 102 on the upper support 100 of the sliding column and the bolts required for the assembly of the other suspension and the vehicle body can be installed and tightened to complete the assembly. After the chassis and the vehicle body are assembled, the guide device 300 is removed from the slide column upper support 100 and used for the assembly of the next batch.

[0039] The spiral guide structure used in the assembly method of this embodiment is simple and reusable, low-cost, and can automatically align the upper support of the sliding column with the mounting hole of the body when the chassis and the body are assembled, thereby avoiding safety risks and significantly improving production efficiency.

[0040] For ordinary technicians in this field, the specific embodiments are only illustrative descriptions of the present invention. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the technical solution of the present invention, they are all within the protection scope of the present invention.
