[0002] The automotive chassis includes systems such as suspension, mounts, powertrain, braking, and steering, connected to the vehicle body via subframes, shock absorbers, and springs. Complete vehicle assembly involves first assembling the chassis in place and then integrating it with the vehicle body. Positioning accuracy during the assembly process significantly impacts vehicle assembly efficiency and quality. With the increasing automation of vehicle assembly, more mechanized assembly is replacing manual work, significantly improving vehicle production efficiency while also placing higher demands on assembly system precision. Traditional assembly systems use a pallet to support the entire chassis, which is then lifted using a lifting device until it aligns with the vehicle body. Once aligned, the subframe, shock absorbers, and springs are then bolted together. The subframe is positioned by fixing it to the pallet using locating holes. The spring interface is typically larger and can be fixed to the swing arm, ensuring proper alignment during assembly. However, shock absorbers typically utilize flexible bushing connections, which can cause wobbling during lifting. Manual straightening during the lifting process results in high labor costs, low positioning accuracy, and reduced efficiency. Summary of the Invention

[0035] The following describes the embodiments of the present invention with reference to the accompanying drawings and preferred embodiments. Those skilled in the art will readily appreciate the other advantages and benefits of the present invention from the disclosure herein. The present invention may also be implemented or applied through various other specific embodiments, and the various details in this specification may be modified or altered based on different viewpoints and applications without departing from the spirit of the present invention. It should be understood that the preferred embodiments are intended only to illustrate the present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that the illustrations provided in the following embodiments are merely schematic illustrations of the basic concept of the present invention. Therefore, the illustrations only show components related to the present invention and are not drawn according to the number, shape, and size of components in actual implementation. In actual implementation, the type, quantity, and proportion of each component may be changed arbitrarily, and the component layout may also be more complex.

[0037] Marriage refers to the process of combining chassis sub-assemblies such as the front and rear suspension with the vehicle body, which is also called the final assembly process in English as "Marriage". The marriage process is the most complicated process in the final assembly workshop. The "combination" and "assembly" of chassis components such as the front and rear suspension with the vehicle body directly affects production output, quality and efficiency. The automatic marriage system for the suspension assembly and the vehicle body provided in the embodiment of the present application is mainly used to assist in the precise docking and combination between the suspension assembly of a car and the vehicle body, thereby assisting in the assembly between the suspension assembly of the car and the vehicle body. The structure of the suspension assembly includes but is not limited to shock absorbers, subframes and system springs. During the assembly process of the suspension assembly and the vehicle body, usually the shock absorbers, subframes and system springs all need to be assembled at points corresponding to the vehicle body.

[0038] like Figure 1As shown, the automatic assembly system of the suspension assembly and the vehicle body includes a lifting device 200, a pallet 300, a support rod assembly 400 and a bracket plate 500, the lifting device 200 is arranged at the bottom of the pallet 300, the bracket plate 500 is arranged on the pallet 300 through the support rod assembly 400, the bracket plate 500 is provided with a fixing groove 510, the fixing groove 510 passes through the bracket plate 500 in the vertical direction, and the fixing groove 510 passes through one side edge of the bracket plate 500 in the horizontal direction, the pallet 300 is used to support the suspension assembly 110, and the fixing groove 510 is used to cooperate with the shock absorber 111 to limit the movement of the shock absorber 111 in the horizontal direction.

[0039] In the above embodiment, when the automatic assembly system of the suspension assembly and the vehicle body is in use, Figure 2 and 3 As shown, the pallet 300 is placed horizontally, the suspension assembly 110 is placed on the pallet 300, and the shock absorber 111 of the suspension assembly 110 is inserted into the fixing groove 510 of the bracket plate 500. The fixing groove 510 passes through one side edge of the bracket plate 500 in the horizontal direction to facilitate the insertion of the shock absorber 111. The bracket plate 500 can limit the shaking of the shock absorber 111. The lifting equipment 200 drives the pallet 300, the suspension assembly 110, the support rod assembly 400 and the bracket plate 500 to rise together, gradually approaching the vehicle body 120 above, until the assembly point on the shock absorber 111 is docked with the corresponding assembly point on the vehicle body 120. After the shock absorber 111 is fitted with the vehicle body 120, the fixation of the shock absorber 111 and the vehicle body 120 is completed. During this process, the position of the shock absorber 111 is fixed by the bracket plate 500. Therefore, it is only necessary to pre-set the movement path of the bracket plate 500. When the bracket plate 500 is in place, the assembly point of the shock absorber 111 is precisely aligned with the corresponding assembly point on the vehicle body 120. This process can prevent shaking of the shock absorber 111 and improve the accuracy of alignment and assembly. The lifting device 200 includes but is not limited to a cylinder and a linear module. The movement path of the lifting device 200 can be pre-set in the control mechanism to achieve automatic movement of the assembly system and complete automatic docking of the assembly points.

[0040] In some embodiments, as Figure 4 and 5As shown, the automatic assembly system of the suspension assembly and the vehicle body also includes a mounting seat 700, which is used to connect the shock absorber 111 and the vehicle body 120. A plurality of positioning holes 710 are provided on the bottom surface of the mounting seat 700. The automatic assembly system of the suspension assembly and the vehicle body includes a plurality of top columns 600 fixed on the bracket plate 500, and the top columns 600 are used to be plugged into and cooperate with the positioning holes 710. The mounting seat 700 can serve as a connecting structure between the shock absorber 111 and the vehicle body 120. During use, the mounting seat 700 is first fixed to the top of the shock absorber 111, and then the suspension assembly 110 is placed on the tray 300. The shock absorber 111 of the suspension assembly 110 is inserted into the fixing groove 510 of the bracket plate 500, and the top column 600 on the bracket plate 500 is inserted into the positioning hole 710 on the bottom surface of the mounting seat 700. In the process of the lifting equipment 200 driving the tray 300 and the suspension assembly 110 to rise, the mounting seat 700 located at the top of the shock absorber 111 will first dock with the assembly point on the vehicle body 120, and then the mounting seat 700 can be directly fixed on the vehicle body 120 to complete the connection between the shock absorber 111 of the suspension assembly 110 and the vehicle body 120. The top column 600 can be moved down to achieve separation from the mounting seat 700.

[0041] In some embodiments, as Figure 4 and 5 FIG. 1 shows an alternative specific form of the mounting base 700 in the above embodiment. The mounting base 700 includes a column 720 and a wing plate 730 connected to the column 720. One end of the column 720 is used to connect to the top end of the shock absorber 111, and the wing plate 730 is used to connect to the vehicle body 120. The lower end of the column 720 is used to be fixed to the shock absorber 111. Specific fixing methods include but are not limited to screwing, welding, and integral connection. For example, as shown in the figure, the lower end of the column 720 is provided with an internal thread 721, which can be used for screwing with the shock absorber 111. The upper end of the column 720 and the upper surface of the wing panel 730 can both be used for transfer and mating with the vehicle body 120. A concave positioning groove 722 can be provided on the upper end of the column 720 to guide and dock with the raised structure on the vehicle body 120, assisting in the rapid positioning and docking of the mounting base 700 with the assembly points on the vehicle body 120. The upper surface of the wing panel 730 needs to abut and mate with the vehicle body 120, and the wing panel 730 and the vehicle body 120 are fixed together by fixing parts. Preferably, the wing panel 730 is fixedly connected to the vehicle body 120 by bolts. Bolt holes 731 are provided on the wing panel 730. After the mounting base 700 and the vehicle body 120 are assembled in place, bolts are passed through the bolt holes 731 from bottom to top to fasten the mounting base 700 and the vehicle body 120. An avoidance groove 520 is provided on the bracket plate 500 and is directly opposite to the bolt through hole 731 . The avoidance groove 520 is used to provide an operating space for a bolt tightening tool to avoid interference caused by the bracket plate 500 .

[0042] In some embodiments, as Figure 4 As shown, a reinforcing rib 740 is provided between the lower surface of the wing panel 730 and the outer wall of the column 720. The reinforcing rib 740 is used to enhance the overall strength of the mounting base 700. After the mounting base 700 is assembled with the vehicle body 120, the wing panel 730 can have stronger support and fixing strength, thereby enhancing the service life of the structural member.

[0043] Specifically, the mounting base 700 is provided with two wing plates 730, which are symmetrically distributed on both sides of the column 720. Each wing plate 730 is provided with a bolt through hole 731. The two symmetrically arranged wing plates 730 can make the force distribution between the mounting base 700 and the vehicle body 120 more uniform, thereby improving the stability of the connection. The top column 600 and the positioning hole 710 are each provided with multiple corresponding ones, such as Figure 4 As shown in the figure, there are four top columns 600 and four positioning holes 710. The positioning holes 710 need to have a certain depth so that the top columns 600 can form a stable fit after being inserted into the positioning holes 710 to prevent side tilting. The depth of the positioning holes 710 is preferably 5-30 mm, but is not limited to this. Those skilled in the art can make a reasonable choice.

[0044] In some embodiments, a slide rail structure can be designed on the bracket plate 500 to adjust the size of the fixing groove 510 and the position of the top column 600, so that the bracket plate 500 can be adapted to shock absorbers 111 and mounting seats 700 of different specifications; in other embodiments, it can be considered to screw the top column 600 to the bracket plate 500, and a large number of screw holes are opened in a matrix form on the bracket plate 500. By screwing the top column 600 to different screw holes, the distribution position of the top column 600 can be adjusted to adapt to mounting seats 700 of different specifications; in other embodiments, it can be considered to provide a number of horizontally arranged screws on the groove wall of the fixing groove 510, and adjust the diameter of the shock absorber 111 that can be accommodated by the protruding length of the screw in the fixing groove 510, so as to adapt to shock absorbers 111 of different specifications.

[0045] The structure for assembling the suspension assembly 110 with the vehicle body 120 generally includes a subframe 112 and a system spring 113 in addition to the shock absorber 111. The system spring 113 is generally provided in two, and the subframe 112 is generally provided with four subframe assemblies 1121 for assembling with the vehicle body 120. During the assembly process of the suspension assembly and the vehicle body through the automatic assembly system provided by the aforementioned embodiment, it is difficult to simultaneously complete the docking of the two shock absorbers 111, the two system springs 113, and the four subframe assemblies 1121 with the vehicle body 120. There will be certain assembly accuracy errors between different assembly points. Therefore, it is necessary to consider docking and assembling each assembly point in batches. Based on this, in some embodiments, such as Figure 1-3 and Figure 6 As shown, the automatic assembly system of the suspension assembly and the vehicle body also includes a guide member 800 and an elastic member 900. The guide member 800 is fixed on the pallet 300, and the elastic member 900 is arranged between the support rod assembly 400 and the pallet 300. The support rod assembly 400 and the guide member 800 slide together in the vertical direction. The guide member 800 guides the support rod assembly 400 to ensure that the support rod assembly 400 slides in the vertical direction without moving or swinging in other directions, thereby ensuring precision control during the docking process. During use, when the tray 300 drives the suspension assembly 110 to lift, the mounting seat 700 on the shock absorber 111 can be matched with the vehicle body 120 first. There is still a certain distance between the other assembly points and the vehicle body 120. At this time, if the lifting is continued, the assembled mounting seat 700 will no longer rise, and the top column 600, the bracket plate 500 and the support rod assembly 400 will no longer rise. Due to the presence of the guide member 800 and the elastic member 900, the support rod assembly 400 and the tray 300 can have a relative movement in the vertical direction. The tray 300 will drive the subframe 112 and the system spring 113 to continue to rise, and finally the subframe 112 and the system spring 113 are completed. The subframe assembly 1121 and the system spring 113 are assembled with the vehicle body 120 respectively. During this process, the shock absorber 111 has an elastic deformation in the vertical direction. Even after the mounting seat 700 is fixed on the vehicle body 120, the subframe 112 can continue to rise and the shock absorber 111 will deform synchronously with the elastic member 900, ensuring that each installation point can be synchronized and accurately positioned. Preferably, before the suspension assembly 110 is lifted, it should be ensured that the stretching amount of the shock absorber 111 in the stretched state (upper limit of length) is about 20mm. The designed compressibility of the elastic member 900 should be greater than the deformation amount of the shock absorber 111, for example, the compression amount is greater than 30mm. At this point, through the arrangement of the guide member 800 and the elastic member 900, different assembly points on the suspension assembly 110 are connected and assembled with the vehicle body 120 in batches. The elastic member 900 is preferably a coil spring.

[0046] Preferably, Figure 1 and Figure 6 As shown, the support rod assembly 400 includes a guide section 410 and a support section 420 that are connected to each other. The guide section 410 is slidably engaged with the guide member 800 , and the support section 420 is fixedly connected to the bracket plate 500 . As shown in the figure, since the shock absorber 111 on the suspension assembly 110 is located on both sides of the suspension assembly 110, the bracket plate 500 that cooperates with the shock absorber 111 and the support rod assembly 400 that supports the bracket plate 500 are also usually arranged at the end of the tray 300, but the shock absorber 111 is only close to the end of the suspension assembly 110, and the outside of the shock absorber 111 usually also has other structures such as a wheel frame. Therefore, the support rod assembly 400 fixed to the end of the tray 300 needs to be bent inward so that the bracket plate 500 can be at the position where the shock absorber 111 is located during operation. In a preferred embodiment, the guide section 410 of the support rod assembly 400 is vertically arranged, and the support section 420 is bent inward relative to the guide section 410. The angle formed between the guide section 410 and the support section 420 is an obtuse angle, thereby achieving corresponding positions between the bracket plate 500 and the shock absorber 111. Specifically, in order to improve the supporting effect of the support rod assembly 400, two guide sections 410, two support sections 420 and two guide members 800 are provided between the tray 300 and the bracket plate 500. The two guide sections 410 are arranged in parallel and connected together by a cross bar 440, so that the two guide sections 410, the two support sections 420 and the cross bar 440 constitute a complete support rod assembly 400. In addition, the design of the dual guide members 800 can effectively avoid the twisting of the support rod assembly 400 during the lifting process, thereby improving the assembly accuracy. The height of the guide cylinder 810 is preferably above 50 mm to ensure better linear guidance and prevent the support rod assembly 400 from tilting.

[0047] In order to adapt to the two shock absorbers 111 of the suspension assembly 110, two groups of the support rod assembly 400 and the bracket plate 500 are provided, and are respectively located at the opposite ends of the tray 300. Each group of support rod group and bracket plate 500 is respectively matched with one shock absorber 111. In this way, the two shock absorbers 111 can be docked and assembled with the vehicle body 120 at the same time through the assembly system.

[0048] In some embodiments, as Figure 6 and 7As shown, the guide member 800 includes a guide cylinder 810 having a first slide 820 and a second slide 830 therein. The first slide 820 is located above the second slide 830. The lower end of the guide section 410 is enlarged to form a stopper 430. The guide section 410 and the first slide 820 are in sliding engagement with each other, and the stopper 430 and the second slide 830 are in sliding engagement with each other. The horizontal cross-section of the first slide 820 matches that of the guide section 410, and the horizontal cross-section of the second slide 830 matches that of the stopper 430. The horizontal cross-section area of the stopper 430 is larger than that of the guide section 410, resulting in a T-shaped vertical cross-section of the guide section 410 and the stopper 430. A step structure is formed at the junction of the first slide 820 and the second slide 830. The T-shaped structure and the step structure are in positional engagement, preventing the stopper 430 from escaping from the guide cylinder 810.

[0049] The embodiment of the present application also separately protects the mounting base 700 in the automatic assembly system of the suspension assembly and the vehicle body. The mounting base 700 is used to connect the shock absorber 111 and the vehicle body 120. A plurality of positioning holes 710 are provided on the bottom surface of the mounting base 700. The automatic assembly system of the suspension assembly and the vehicle body includes a plurality of top columns 600 fixed on the bracket plate 500. The top columns 600 are used to be plugged into and cooperate with the positioning holes 710. The mounting base 700 can serve as a connecting structure between the shock absorber 111 and the vehicle body 120. During use, the mounting base 700 is first fixed to the top of the shock absorber 111, and then the suspension assembly 110 is placed on the tray 300. The shock absorber 111 of the suspension assembly 110 is inserted into the fixing groove 510 of the bracket plate 500, and the top column 600 on the bracket plate 500 is inserted into the positioning hole 710 on the bottom surface of the mounting base 700. When the lifting device 200 drives the tray 300 and the suspension assembly 110 to rise, the mounting base 700 located at the top of the shock absorber 111 will first dock with the assembly point on the vehicle body 120, and the mounting base 700 is directly fixed to the vehicle body 120, thereby completing the connection between the shock absorber 111 of the suspension assembly 110 and the vehicle body 120. The specific structure and technical effects of the mounting base 700 can be found in the specific embodiment of the automatic assembly system of the suspension assembly and the vehicle body, which will not be repeated here.

Specifically, the vehicle includes a chassis and a body 120. The chassis includes a suspension assembly 110. The shock absorber 111 of the suspension assembly 110 is connected to the body 120 via the mounting base 700.
