[0024] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0025] Reference below Figure 1 and Figure 2 A suspension assembly 1 according to an embodiment of the present invention is described.

[0026] like Figure 1 As shown, the suspension assembly 1 according to an embodiment of the present invention includes a lower arm 10, a first buffer assembly 20, and a second buffer assembly 30. The lower arm 10 primarily supports the vehicle body and provides shock absorption, weight support, and steering. The first buffer assembly 20 and the second buffer assembly 30 primarily enhance the vehicle's shock absorption performance, protecting the vehicle, driver, and passengers.

[0027] like Figure 1As shown, the first buffer assembly 20 includes a first fixing member 200 and a first elastic member 201. The first fixing member 200 is connected to the lower arm 10, and one end of the first elastic member 201 is connected to the first fixing member 200. The first fixing member 200 is mainly used to fix and install other components, and the first elastic member 201 is mainly used to provide elastic force, which plays a role in elastic adjustment and buffering. The first fixing member 200 is connected to the lower arm 10, and the first fixing member 200 and the lower arm 10 form a whole, which facilitates the installation and configuration of the suspension assembly 1. One end of the first elastic member 201 is connected to the first fixing member 200, and the first elastic member 201 and the first fixing member 200 form a whole, which facilitates the installation and configuration of the first buffer assembly 20. The first elastic member 201 can be a coil spring.

[0028] like Figure 1 As shown, the second buffer assembly 30 includes a second fixing member 300, a support member 301, and a second elastic member 302. The second fixing member 300 primarily secures other components, the support member 301 primarily provides support, and the second elastic member 302 primarily provides elastic force, providing elastic adjustment and buffering. The second elastic member 302 may be a coil spring.

[0029] like Figure 1As shown, the second fixing member 300 is located on one side of the first fixing member 200, and the second fixing member 300 is suitable for being connected to the vehicle frame. The support member 301 is located between the first fixing member 200 and the second fixing member 300, and the support member 301 can move toward or away from the second fixing member 300. The second elastic member 302 is connected between the second fixing member 300 and the support member 301, and the other end of the first elastic member 201 is connected to the second fixing member 300. The second fixing member 300 is located on one side of the first fixing member 200. The second fixing member 300 is set on one side of the first fixing member 200. The second fixing member 300 is suitable for connecting with the frame. At this time, the second fixing member 300 and the frame form a whole, which is convenient for the installation and setting of the second fixing member 300. The support member 301 is located between the first fixing member 200 and the second fixing member 300, and the support member 301 can move toward or away from the second fixing member 300. The support member 301 is set between the first fixing member 200 and the second fixing member 300. 01 can move between the first fixing member 200 and the second fixing member 300 toward or away from the second fixing member 300. The second elastic member 302 is connected between the second fixing member 300 and the support member 301. At this time, the second elastic member 302, the second fixing member 300 and the support member 301 form a whole, which is convenient for the installation and setting of the second buffer component 30. The other end of the first elastic member 201 is connected to the second fixing member 300. At this time, the first buffer component 20 and the second buffer component 30 are connected to form a whole, which is convenient for the installation and setting of the suspension assembly 1. It should be noted that the second fixing member 300 can be welded to the frame using a dedicated welding machine. This can make the weld smooth, the size precise, the structure simple and elegant, and can ensure the firmness and reliability of the connection between the second fixing member 300 and the frame.

[0030] Therefore, the first elastic member 201 and the second elastic member 302 are arranged in parallel, which is suitable for no-load and full-load conditions. It can have good driving and riding comfort when no-load, and can also obtain greater suspension stiffness when fully loaded, meeting safety requirements.

[0031] Specifically, if Figure 1 As shown, the second elastic member 302 is sleeved over a portion of the first elastic member 201. This reduces the overall structure and weight of the elastic member, thereby reducing the layout space of the suspension assembly 1. Furthermore, this improves passenger safety during vehicle operation and reduces installation time, significantly improving vehicle loading efficiency and reducing maintenance costs.

[0032] Among them, such as Figure 1 and Figure 2As shown, the outer diameter of the first elastic member 201 is smaller than the inner diameter of the second elastic member 302, and the length of the first elastic member 201 is greater than the length of the second elastic member 302. The outer diameter of the first elastic member 201 is smaller than the inner diameter of the second elastic member 302, so that the second elastic member 302 can be sleeved on a portion of the first elastic member 201. The length of the first elastic member 201 is greater than the length of the second elastic member 302. The second elastic member 302 is connected between the second fixing member 300 and the support member 301, and the first elastic member 201 is connected between the second fixing member 300 and the first fixing member 200. When the length of the first elastic member 201 is greater than the length of the second elastic member 302, the arrangement of the first fixing member 200 and the support member 301 is more consistent with actual working conditions. In addition, compression of the first elastic member 201 can cause the first fixing member 200 and the support member 301 to contact.

[0033] In addition, if Figure 1 and Figure 2 As shown, the second buffer assembly 30 further includes a guide member 303, one end of which is fixed to the second fixing member 300, and the other end of which passes through the support member 301, so that the support member 301 can move along the guide member 303. The guide member 303 mainly serves as a guide. One end of the guide member 303 is fixed to the second fixing member 300, and the guide member 303 and the second fixing member 300 form a whole, which facilitates the installation and configuration of the second buffer assembly 30. The other end of the guide member 303 passes through the support member 301, that is, the other end of the guide member 303 is installed and configured in conjunction with the support member 301, and the support member 301 can move along the guide member 303, that is, the support member 301 can move in the direction of the guide member 303. It should be noted that the guide member 303 and the second fixing member 300 can be welded using a dedicated welding machine, which can make the weld smooth, the size accurate, the structure simple and elegant, and can ensure the firmness and reliability of the connection between the guide member 303 and the second fixing member 300.

[0034] Of course, if Figure 1 and Figure 2 As shown, the second buffer assembly 30 further includes a fixing sleeve 304, which is disposed on the side of the support member 301 away from the second fixing member 300 and is fixedly connected to the other end of the guide member 303. The fixing sleeve 304 primarily serves a fixing function. The fixing sleeve 304 is disposed on the side of the support member 301 away from the second fixing member 300, that is, the support member 301 is disposed between the fixing sleeve 304 and the second fixing member 300. The fixing sleeve 304 is fixedly connected to the other end of the guide member 303. The fixing sleeve 304 and the guide member 303 form a single unit, facilitating installation and configuration of the second buffer assembly 30. The fixing sleeve 304 can be configured as a nut cap.

[0035] Furthermore, if Figure 1 and Figure 2 As shown, the fixing sleeve 304 is closed at one end away from the support member 301. An internal thread is provided in the fixing sleeve 304, and an external thread is provided at the other end of the guide member 303. The internal thread and the external thread are threadedly matched. The fixing sleeve 304 is closed at one end away from the support member 301. This can serve as a limiter, allowing the support member 301 to be installed parallel to the second fixing member 300. The fixing sleeve 304 is internally provided with an internal thread, and the other end of the guide member 303 is externally provided with an external thread. The internal thread and the external thread are threadedly matched, thus forming a threaded structure between the guide member 303 and the fixing sleeve 304. At this time, the installation and disassembly between the guide member 303 and the fixing sleeve 304 are convenient, easy to use, highly practical, structurally reliable, and can save maintenance costs. In addition, the arrangement of the guide member 303 and the fixing sleeve 304 can be made more in line with actual working conditions.

[0036] In addition, Figure 1 and Figure 2 As shown, there are multiple guide members 303, and the multiple guide members 303 are arranged at intervals on the outer peripheral side of the second elastic member 302. The multiple guide members 303 are provided, and the multiple guide members 303 can play a limiting role, thereby ensuring that the support member 301 can move linearly along the guide members 303, and the extension and compression of the second elastic member 302 can be limited. The multiple guide members 303 are arranged at intervals on the outer peripheral side of the second elastic member 302, so as to avoid interference between the multiple guide members 303, and at the same time, the distribution range of the multiple guide members 303 can be wider, and to a certain extent, the limiting effect of the guide members can also be improved.

[0037] It should be noted that if Figure 1 As shown, the first buffer component 20 also includes: a first buffer part 202, and the second buffer component 30 also includes: a second buffer part 305 and a third buffer part 306. The first buffer part 202 is arranged on the side of the first fixing part 200 facing the second fixing part 300, the second buffer part 305 is arranged on the side of the support part 301 facing the second fixing part 300, and the third buffer part 306 is arranged on the side of the second fixing part 300 facing the first fixing part 200. The first elastic part 201 abuts between the first buffer part 202 and the third buffer part 306, and the second elastic part 302 abuts between the second buffer part 305 and the third buffer part 306.

[0038] It should be noted that the first buffer member 202, the second buffer member 305 and the third buffer member 306 can all play a role in buffering and shock absorption. The first buffer member 202 is arranged on the side of the first fixing member 200 facing the second fixing member 300, the second buffer member 305 is arranged on the side of the support member 301 facing the second fixing member 300, and the third buffer member 306 is arranged on the side of the second fixing member 300 facing the first fixing member 200. The first buffer member 202, the second buffer member 305 and the third buffer member 306 are respectively vulcanized to the first fixing member 200, the support member 301 and the second fixing member 300 by rubber vulcanization. On the fixing part 300, the first elastic part 201 abuts between the first buffer part 202 and the third buffer part 306, and the second elastic part 302 abuts between the second buffer part 305 and the third buffer part 306. In this way, the first elastic part 201 can be connected to the first fixing part 200 and the second fixing part 300. At this time, the first fixing part 200 and the second fixing part 300 can realize the limitation of the first elastic part 201, and the second elastic part 302 is connected between the support part 301 and the second fixing part 300. At this time, the support part 301 and the second fixing part 300 can realize the limitation of the second elastic part 302.

[0039] In addition, if Figure 1 and Figure 2 As shown, the first buffer assembly 20 further includes a fastener 203, through which the first fixing member 200 is connected to the lower swing arm 10. The fastener 203 primarily serves to fasten the connection.
