The second end 11b can be but is not limited to the right end. The first end 11a is used to connect to the subframe (not shown in the figure). Among them, the first end 11a is detachably or fixedly connected to the subframe. The second end 11b is used to connect to the brake and / or shock absorber. Among them, the second end 11b is detachably or fixedly connected to the brake; and / or, the second end 11b is detachably or fixedly connected to the shock absorber.

[0032] The mounting seat 12 is releasably locked to the middle part of the spring arm main body 11. Among them, the mounting seat 12 can be locked to the middle part of the spring arm main body 11; or, the mounting seat 12 is unlocked from the middle part of the spring arm main body 11.

When the mounting seat 12 is locked to the middle part of the spring arm main body 11, the adjusting assembly 13 can be used to adjust the height of the mounting seat 12 relative to the spring arm main body 11 in the first direction (not shown in the figure). Among them, the first direction can be but is not limited to the vertical direction. The adjusting assemblies 13 on different mounting seats 12 can meet the height requirements in the first direction, so that the mounting seat 12 can be used as an independent component to make serialized matching products to meet the needs of different vehicle models on the same platform. That is, the mounting seat 12 can be the core component for realizing the Z-direction position transformation of the spring seats of different vehicles, vehicle height adjustment, and suspension stiffness adjustment, and can be divided into high-end vehicle models and low-end vehicle models.

[0034] The adjusting assembly 13 can be but is not limited to a limit platform structure, an electromagnet structure, and an elastic structure, etc. The above-mentioned subframe, brake, shock absorber, and spring seat, etc. are conventional components in the art and are not limited herein.

[0035] Since the adjusting component 13 is disposed on the mounting base 12 and the mounting base 12 is detachably locked to the middle of the spring arm main body 11, only the mounting base 12 that meets the requirements needs to be replaced according to different vehicle heights, rather than replacing the entire spring arm assembly 10, which can realize the universality of the spring arm main body 11, so as to meet the adjustment of different vehicle heights. Further, the adjusting component 13 can adjust the height of the mounting base 12 relative to the spring arm main body 11 along the first direction, realize the adjustable height of the spring seat, so as to realize the adjustment of the vehicle height, and can also realize the adjustment of the suspension stiffness. According to the vehicle operating conditions, the dynamic and timely adjustment of the suspension stiffness can affect the dynamic response of the whole vehicle, and thus can be widely applied and promoted in the field of passenger cars.

[0036] Please refer to Figure 4 and Figure 5 , Figure 4 is the second structural schematic diagram of an embodiment of the spring arm assembly of the present application; Figure 5 is the structural schematic diagram of the spring arm main body in the spring arm assembly of the present application. Combining Figures 1 to 3 , in some embodiments, a receiving groove 1112 is formed in the middle of the spring arm main body 11. The receiving groove 1112 is located between the first end 11a and the second end 11b. The receiving groove 1112 provides an installation position for the above-mentioned mounting base 12. The mounting base 12 includes a mounting base body 121 and a plugging portion 122. The plugging portion 122 is disposed on one side surface of the mounting base body 121. Among them, the plugging portion 122 is detachable or fixed to one side surface of the mounting base body 121. As in this embodiment, the plugging portion 122 is integrally formed on one side surface of the mounting base body 121. The number of the plugging portions 122 can be but is not limited to one, two, three or more, etc. As in this embodiment, the number of the plugging portions 122 is two and they are symmetrically arranged respectively.

[0037] The adjusting component 13 includes a first sub-adjusting component 131. The first sub-adjusting component 131 is disposed on the outer periphery of the plugging portion 122. Among them, the first sub-adjusting component 131 is detachable or fixed to the outer periphery of the plugging portion 122. The plugging portion 122 is detachably locked to the receiving groove 1112. Among them, the plugging portion 122 can be locked to the receiving groove 1112; or, the plugging portion 122 is unlocked from the receiving groove 1112. The detachable locking method between the plugging portion 122 and the receiving groove 1112 can be but is not limited to snap locking, plugging locking, bolt locking, etc. When the plugging portion 122 is locked to the receiving groove 1112, the first sub-adjusting component 131 abuts against the bottom wall of the receiving groove 1112, which is used to limit the height of the mounting base 12 in the receiving groove 1112, and thus can adjust the height of the mounting base 12 relative to the spring arm main body 11. The first sub-adjusting component 131 can be but is not limited to a limiting platform structure, a boss structure, etc.

[0038] Through the combined action of the above-mentioned spring arm body 11, receiving groove 1112, mounting seat body 121, plug-in portion 122, and first sub-adjustment component 131, during the process of locking the mounting seat 12 to the spring arm body 11 through the plug-in portion 122, the first sub-adjustment component 131 can change the height of the mounting seat 12 relative to the spring arm body 11. That is, according to the height requirements of different vehicles, by replacing the mounting seat 12 at different positions on the plug-in portion 122 of the first sub-adjustment component 131, the height differential design of the spring seats for different vehicle models on the same platform is realized; the generalization rate of the same platform is improved.

[0039] In a specific embodiment, the first sub-adjustment component 131 includes an adjustment limiting portion 1311. The adjustment limiting portion 1311 is disposed around the outer peripheral surface of the plug-in portion 122. Among them, the adjustment limiting portion 1311 is fixed or integrally formed on the outer peripheral surface of the plug-in portion 122. The plug-in portion 122 can be plugged and locked into the receiving groove 1112. Among them, the plug-in portion 122 is plugged into the receiving groove 1112 by a plugging method, and then the plug-in portion 122 is locked in the receiving groove 1112. When the plug-in portion 122 is plugged and locked into the receiving groove 1112, the adjustment limiting portion 1311 abuts against the bottom wall of the receiving groove 1112. The heights of both the top end of the plug-in portion 122 and the adjustment limiting portion 1311 can be different according to different mounting seats 12, so as to realize the height differential design of the spring seats for different vehicle models on the same platform, and further improve the generalization rate of the same platform, etc.

[0040] In some embodiments, the spring arm body 11 is provided with a plug-in hole 1113. The plug-in hole 1113 is located in the receiving groove 1112. The plug-in hole 1113 is a positioning and installation mating hole for the plug-in portion 122. The plug-in portion 122 is plugged into the plug-in hole 1113. That is, the plug-in portion 122 is plugged into the spring arm body 11 by a plugging method. The spring arm body 11 is provided with a first mounting hole 1114. The plug-in portion 122 is provided with a second mounting hole 1221. A fixing member 14 passes through the first mounting hole 1114 and the second mounting hole 1221. The fixing member 14 plays a connecting role and can lock the mounting seat 12 to the middle of the spring arm body 11. When it is necessary to replace different mounting seats 12, only the fixing member 14 needs to be disassembled and assembled.

[0041] Through the combined cooperation of the above-mentioned plug-in portion 122, plug-in hole 1113, first mounting hole 1114, second mounting hole 1221, and fixing member 14, etc., it is not only convenient for the mounting seat 12 to be quickly installed on the spring arm body 11, but also the installation is firm, and at the same time, the structure is simple and easy to install and operate, etc.

[0042] Please refer to Figure 6 , Figure 6 which is a schematic structural diagram of the stabilizer link in the spring arm assembly of the present application. In combination with Figures 1 to 5, in some embodiments, the spring arm assembly 10 includes a stabilizer link 15. The stabilizer link 15 can integrate a stabilizer bar (not shown in the figure) on the spring arm assembly 10, and the stabilizer link 15 can transmit torsion and torque, etc. One end of the stabilizer link 15 is sleeved on one end of the fixing member 14. Specifically, one end of the stabilizer link 15 is clamped or inserted into one end of the fixing member 14. The other end of the stabilizer link 15 is used to connect the stabilizer bar. Through the cooperation of the stabilizer link 15 and the fixing member 14, not only can the stabilizer link 15 be directly integrated on the fixing member 14, but also there is no need to develop other positions on the spring arm assembly 10, reducing costs, etc.

[0043] Specifically, the fixing member 14 is a fixing bolt. The fixing bolt is threadedly connected to the stabilizer link 15, which not only realizes the locking connection between the mounting seat 12 and the spring arm body 11, but also integrates the connection of the stabilizer link 15, thereby realizing the installation of the stabilizer bar, and at the same time, the structure is simple and easy to operate and install, etc.

[0044] In some embodiments, the spring arm body 11 includes two spring arms 111. The two spring arms 111 are arranged at an angle. Specifically, one end of the two spring arms 111 is fixed or integrally formed, and the other ends of the two spring arms 111 are bifurcated. The two spring arms 111 are convexly provided with extension parts 1111. Specifically, one side of one spring arm 111 away from the other spring arm 111 is convexly provided with an extension part 1111; the other side of the other spring arm 111 away from one spring arm 111 is convexly provided with another extension part 1111. A receiving groove 1112 is formed between the two spring arms 111 and the two extension parts 1111. The mounting seat 12 includes two insertion parts 122. The insertion parts 122 can be detachably locked to the corresponding extension parts 1111. Specifically, the insertion parts 122 are locked on the corresponding extension parts 1111; or, the insertion parts 122 are unlocked from the corresponding extension parts 1111.

[0045] Through the cooperation of the two spring arms 111, the two extension parts 1111 and the two insertion parts 122, etc., not only the strength of the mounting seat 12 installed on the spring arm body 11 is improved, but also the smoothness of the mounting seat 12 installed on the spring arm body 11 can be increased.

[0046] Specifically, each spring arm 111 is provided with a first mounting hole 1114. Each insertion part 122 is provided with a second mounting hole 1221. The fixing member 14 sequentially passes through the second mounting hole 1221, the first mounting hole 1114, the first mounting hole 1114 and the second mounting hole 1221, and then locks the two insertion parts 122 to the corresponding spring arms 111.

The fixing member 14 is threadedly connected to the above-mentioned first threaded hole and the second threaded hole, not only stably integrating the mounting seat 12 on the spring arm main body 11, but also having a simple structure and being easy to install and operate, etc.

[0048] Furthermore, the accommodating groove 1112 is circularly arranged; the mounting seat 12 is circularly arranged. Both of the two extending portions 1111 are arc-shaped and symmetrically arranged. The above-mentioned circular accommodating groove 1112 is formed by enclosing the two extending portions 1111 and the two spring arms 111.

[0049] In some embodiments, during the process of inserting the inserting portion 122 into the accommodating groove 1112, the inserting portion 122 is inserted outside the extending portion 1111; at the same time, the inserting portion 122 is located outside the spring arm 111. By defining the relative position of the inserting portion 122 with respect to the spring arm 111, not only the mounting strength of the mounting seat 12 on the spring arm main body 11 is improved, but also the stability of the mounting seat 12 on the spring arm main body 11 is improved.

[0050] In some embodiments, a weight-reducing hole 1211 is provided on the upper surface of the mounting seat 12. The weight-reducing hole 1211 can play a role in weight reduction. In addition, a positioning hole 1212 is also provided on the upper surface of the mounting seat 12. The positioning hole 1212 is used for spring seat positioning. For example, the positioning hole 1212 is used for positioning a spring pad (not shown in the figure) on the spring seat.

[0051] Please refer to Figure 7 and Figure 8 , Figure 7 is the second schematic structural view of the mounting seat in the spring arm assembly of the present application; Figure 8 is the schematic structural view of the first mounting seat in the spring arm assembly of the present application.

Among them, the second sub-adjustment component 132 can be, but is not limited to, an electromagnet structure, a spring structure, etc., as long as it can change the height of the first mounting seat 123 relative to the second mounting seat 124.

[0053] By separately arranging the mounting seat 12 and setting the second sub-adjustment component 132 between the first mounting seat 123 and the second mounting seat 124, the height of the mounting seat 12 relative to the spring arm main body 11 can be further adjusted, and thus the height requirements of different vehicle models can be better met.

[0054] In a specific embodiment, the second sub-adjustment component 132 includes an electromagnet assembly (not shown in the figure).
