[0030] With the continuous prosperity and development of modern life, cars play an increasingly important role in human life. Cars have changed people’s travel methods and shortened the distance between different regions.

[0031] Automobile suspension is an extremely important component in a car. It helps to improve and alleviate the impact vibration caused by factors such as vehicle speed and road conditions during driving. It helps to improve the riding experience of passengers and improve the driving comfort and safety of drivers.

[0032] There are various suspension systems for modern cars, which are mainly composed of multiple components such as elastic elements, shock absorbers, guide mechanisms, etc. The shock absorbers of the car suspension play a role in overall shock absorption of the car. When the shock absorbers need to be adjusted, tools are usually required, which makes the adjustment extremely inconvenient.

[0033] In order to solve the technical problems existing in the related art, the present application provides a shock absorber, see Figure 1 and Figure 2 , Figure 1 is a structural schematic diagram of a first state of the shock absorber provided by the present application; Figure 2 It is a structural schematic diagram of the second state of the shock absorber provided by the present application.

[0034] The shock absorber 10 includes a fixed plate 100, a damper 200, an adjusting assembly 300, an elastic member 400, and a rotating rod 500; the damper 200 is connected to the fixed plate 100; the adjusting assembly 300 is sleeved on the outer side of the damper 200, and the adjusting assembly 300 and the fixed plate 100 are spaced apart in the axial direction Y of the damper 200; the elastic member 400 is sleeved on the outer side of the damper 200, and the elastic member 400 is elastically supported between the fixed plate 100 and the adjusting assembly 300; the rotating rod 500 is connected to the adjusting assembly 300, and the rotating rod 500 is used to drive the adjusting assembly 300 to rotate along the circumferential direction Z of the damper 200 in the first state, so that the adjusting assembly 300 is close to or away from the fixed plate 100 in the axial direction Y, so as to adjust the compression amount of the elastic member 400.

[0035] The elastic member 400 may refer to a shock absorbing spring on the shock absorber, which is located between the fixed plate 100 and the adjustment assembly 300 and is sleeved on the outside of the damper 200. When the shock absorber is installed on the vehicle, when the wheels of the vehicle are impacted by the road surface, the vibration is transmitted to the shock absorbing spring of the shock absorber, causing the spring to oscillate back and forth, and the damper 200 works at the same time to suppress the oscillation of the shock absorbing spring, thereby gradually unloading the impact force. The shock absorbing spring is arranged between the fixed plate 100 and the adjustment assembly 300. The fixed plate 100 can be fixedly connected to the body of the vehicle, so that the fixed plate 100 cannot move, and the adjustment assembly 300 can move along the axial direction Y of the damper 200 to change the distance between the adjustment assembly 300 and the fixed plate 100. When the adjustment assembly 300 moves in the direction close to the fixed plate 100, the shock absorbing spring is compressed; when the adjustment assembly 300 moves in the direction away from the fixed plate 100, the shock absorbing spring is expanded, thereby achieving the adjustment of the shock absorber.

[0036] The rotating rod 500 can be hinged on the outside of the adjusting assembly 300. When the distance between the adjusting assembly 300 and the fixing plate 100 needs to be changed, the rotating rod 500 can be placed in the first state, so that the user can hold the rotating rod and apply external force, so that the rotating rod 500 drives the adjusting assembly 300 to rotate along the circumferential direction Z of the damper 200. After the distance between the adjusting assembly 300 and the fixing plate 100 is adjusted, the rotating rod 500 can be moved from the first state to the second state. Figure 1 The first state shown changes to Figure 2 The second state is shown.

[0037] Through the above-mentioned embodiment, the rotating rod 500 is connected to the adjusting assembly 300, and the rotating rod 500 can drive the adjusting assembly 300 to rotate along the circumferential direction Z of the damper 200, so that the adjusting assembly 300 can adjust the compression amount of the elastic member 400 close to or away from the fixed plate 100 in the axial direction Y. The compression amount of the elastic member 400 can be adjusted without the need for additional tools, thereby improving the convenience of adjusting the compression amount of the elastic member 400.

[0038] Specifically, the damper includes a locking portion 210, which is located at one end of the damper 200 away from the fixed plate 100. The rotating rod 500 is connected to the locking portion 210 in the second state to limit the adjustment assembly 300 in the circumferential direction Z. The rotating rod 500 is extended along the axial direction Y in the second state.

[0039] The locking part 210 may include a horizontal plate and a rubber sleeve. The horizontal plate is fixedly arranged on the end of the damper 200 away from the fixing plate 100. A rubber sleeve is arranged above the horizontal plate. The interior of the rubber sleeve is in a hollow state. After adjusting the position of the adjustment assembly 300, the rotating rod 500 is moved from the position as shown in FIG. Figure 1 The first state shown changes to Figure 2 The second state shown is such that the rotating rod 500 is attached to the outside of the damper 200 along the axial direction Y of the damper 200. The rotating rod 500 may have a telescopic function, so that the length of the rotating rod 500 can be adjusted, so that when the rotating rod is in the second state, the rotating rod 500 is closed and attached to the outside of the damper 200 along the axial direction Y of the damper 200, and is connected to the locking portion 210. At this time, the adjusting assembly 300 can be limited in the circumferential direction Z by the rotating rod 500, thereby fixing the position of the adjusting assembly 300.

[0040] Furthermore, the rotating rod includes a first rod segment 510 and a second rod segment 520 , which are plug-fitted together, one of the first rod segment 510 and the second rod segment 520 is connected to the adjustment assembly 300 , and the other is used to connect to the locking portion 210 .

[0041] The rotating rod 500 can be a telescopic disassembly rod, which can be freely extended and can have 2 sections or more, such as 3 sections, 4 sections, 5 sections, etc., which is not limited to the present application. Only the part connected to the rotating rod 500 and the adjustment assembly 300 is called the first rod section 510, and the part connected to the rotating rod 500 and the locking portion 210 is called the second rod section 520. At this time, the rotating rod 500 can be turned to rotate the adjustment assembly 300 along the circumferential direction Z of the damper 200, so that the adjustment assembly 300 moves up and down along the axial direction Y of the damper 200, thereby adjusting the tightness of the shock absorber spring of the shock absorber. Specifically, the rotating rod 500 can be extended and retracted to obtain a suitable length, and its second rod section 520 can be inserted into the rubber sleeve to fix and limit the adjustment assembly 300. It can be understood that the rotating rod 500 plays a supporting and fixing role at this time, and the connection between the rotating rod 500 and the locking portion 210 can also play a role in limiting the adjustment assembly 300.

[0042] In some embodiments, there are multiple rotating rods 500, and the multiple rotating rods 500 are arranged at intervals along the circumferential direction Z. The number of rotating rods 500 can be 2, and they are arranged at intervals on the outer circumference of the adjustment component 300. When the rotating rods 500 are in the first state, the two rotating rods 500 can be moved at the same time to adjust the shock absorber. In some other embodiments, the number of rotating rods 500 can also be 4, 6, etc., depending on the actual situation, which is not limited to this application.

[0043] In some embodiments, the adjustment assembly 300 includes a first adjustment portion 310 and a second adjustment portion 320 connected to each other, the first adjustment portion 310 and the second adjustment portion 320 are both sleeved on the outside of the damper 200, the second adjustment portion 320 is closer to the fixing plate 100 than the first adjustment portion 310, the size of the second adjustment portion 320 in the radial direction X of the damper 200 is larger than the size of the first adjustment portion 310 in the radial direction X, the elastic member 400 is sleeved between the fixing plate 100 and the second adjustment portion 320, and the rotating rod 500 is connected to the first adjustment portion 310. The second adjustment portion 320 is closer to the fixing plate 100 than the first adjustment portion 310, one end face of the second adjustment portion 320 abuts against one end of the elastic member 400, and the other end face abuts against the first adjustment portion 310. The dimension of the second adjusting portion 320 along the radial direction X of the damper 200 is larger than the dimension of the first adjusting portion 310 along the radial direction X, so that the elastic member 400 can be easily pressed against the second adjusting portion 320, and the elastic member 400 can be easily squeezed by the second adjusting portion 320 when the first adjusting portion 310 moves. The rotating rod 500 can be connected to the first adjusting portion 310, and when the rotating rod 500 drives the first adjusting portion 310 to rotate, the first adjusting portion 310 can drive the second adjusting portion 320 to rotate together, or the second adjusting portion 320 only moves along the axial direction Y during the process of the first adjusting portion 310 rotating and moving along the axial direction Y, without rotating synchronously with the first adjusting portion 310 along the circumferential direction Z.

[0044] Specifically, an inner wall of the first adjusting portion 310 is provided with an internal thread, and an outer wall of the damper 200 is provided with an external thread 220 . The first adjusting portion 310 and the damper 200 are threadedly connected via the internal thread and the external thread 220 .

[0045] By setting the internal and external threads 220, when the first adjusting portion 310 rotates along the circumferential direction Z of the damper 200, the first adjusting portion 310 moves up and down along the axial direction Y of the damper 200; thus, the movement of the first adjusting portion 310 also moves the second adjusting portion 320, thereby adjusting the shock absorber. It can be understood that the user can rotate the first adjusting portion 310 forward or reverse by turning the rotating rod 500, so that the shock absorber can be adjusted without the help of tools.

[0046] In some embodiments, the shock absorber 10 further includes a brush rod 600, which is extended along the axial direction Y, and a portion of the brush rod 600 is sandwiched between the damper and the first adjustment portion 310, and the brush rod 600 is used to rotate during the rotation of the first adjustment portion 310 along the circumferential direction Z. The brush rod 600 may include a first brush rod and a second brush rod, the first brush rod is fixedly arranged on the first adjustment portion 310, and the second brush rod 600 is fixedly arranged on the second adjustment portion 320. When the adjustment assembly 300 moves up and down along the axial direction of the damper 200, the brush rod will also move in a direction close to or away from the fixing plate 100, thereby cleaning the external thread 220.

[0047] Specifically, there are multiple brush rods 600 , and the multiple brush rods 600 are arranged at intervals along the circumferential direction Z.

[0048] The first brush rod and the second brush rod are attached to the outside of the external thread 220. When the first adjustment portion 310 rotates, the first brush rod also rotates, so that the external thread 220 provided on the outer wall of the damper 200 can be cleaned. In one embodiment, the number of the brush rods 600 can be 4, or other numbers, such as 2, 3, etc.; it is not limited here, and the number of the brush rods 600 depends on the actual situation.

[0049] In summary, the shock absorber 10 provided in the present application can adjust the compression amount of the elastic member 400 by adjusting the position of the adjusting component 300 in the axial direction Y of the damper 200, and the adjusting component 300 can be driven to rotate by toggling the rotating rod 500 in the first state, thereby moving and adjusting the position of the adjusting component 300 along the axial direction Y of the damper 200, thereby adjusting the compression amount of the elastic member 400; this makes it possible to adjust the shock absorber 10 without the aid of tools, thereby solving the problem of being inconvenient to adjust the shock absorber 10 when no tools are carried.

[0052] The vehicle may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. In this embodiment, the above shock absorber 10 and the suspension assembly 1 are installed on the vehicle. When the shock absorber 10 needs to be adjusted when encountering different complex road conditions outdoors, and when no tools are carried and there is no auto repair shop nearby; the user can rotate the adjustment assembly 300 by rotating the rotating rod 500 to adjust the position of the adjustment assembly 300, and then adjust the tightness of the shock absorber spring of the shock absorber 10, thereby improving the convenience of adjustment.
