Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electric vehicle shock absorbers, in particular to an electric vehicle shock absorber. Background Art
[0002] Electric vehicle shock absorbers are instruments used to suppress the shock caused by the spring rebounding after absorbing the shock and the impact from the road surface;
[0003] When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jumping. If the shock absorber is too soft, the car body will jump up and down. If the shock absorber is too hard, it will bring too much resistance and hinder the normal operation of the spring. In the process of modifying the suspension system, a hard shock absorber should be matched with a hard spring, and the hardness of the spring is closely related to the weight of the car. Therefore, heavier cars generally use harder shock absorbers, which are connected to the shock-inducing crankshaft to counteract the torsional vibration of the crankshaft (that is, the phenomenon that the crankshaft twists due to the impact of cylinder ignition);
[0004] When the current electric vehicle shock absorber is in use, due to long-term use, the shock-absorbing spring will inevitably lead to weakened contraction and expansion functions, and because the shock absorber does not have a shock absorption degree adjustment mechanism, it needs to be replaced, which makes the overall service life of the shock absorber shorter, increases the economic cost investment, and is more troublesome to replace, which brings inconvenience to the staff. Utility Model Content
[0005] In view of the deficiencies in the prior art, the utility model provides an electric vehicle shock absorber, which solves the problem that the current electric vehicle shock absorber, due to long-term use, the shock absorbing spring will inevitably lead to weakened contraction and expansion functions, and because the shock absorber does not have a shock absorption degree adjustment mechanism, it needs to be replaced, which makes the overall service life of the shock absorber shorter, increases the economic cost investment, and is more troublesome to replace, thus causing inconvenience to the staff.
[0006] To achieve the above-mentioned purpose, the utility model is implemented through the following technical solutions: an electric vehicle shock absorber comprises a first mounting frame, a second mounting frame is arranged above the first mounting frame, and the electric vehicle shock absorber also comprises: a shock absorbing mechanism, which is arranged between the first mounting frame and the second mounting frame; an adjustment mechanism, which is arranged above the shock absorbing mechanism; the shock absorbing mechanism comprises: a sleeve, which is installed on the top of the first mounting frame; a vertical rod, which is arranged above the sleeve; a limit block, which is installed at the bottom of the vertical rod and is movably connected to the inner wall of the sleeve; a damping pad, which is installed on the inner wall of the sleeve and is movably connected to the outer wall of the limit block; a spring, which is fixedly connected to the lower part of the outer wall of the sleeve and extends to the top of the vertical rod. ; The adjusting mechanism comprises: a torsion tube, which is threadedly connected to the outer wall of the vertical rod; a top plate, which is fixedly connected to the top of the spring and movably connected to the bottom of the torsion tube; a slider, which is installed on the top of the top plate and is slidably engaged with the inner wall of the torsion tube; wherein the shock absorbing mechanism can realize the shock absorbing and buffering function, and the adjusting mechanism can change the use state of the shock absorbing mechanism. When the vertical rod moves along the inner wall of the sleeve, the spring can be compressed so that the buffering work can be realized by the elastic force of the spring. The elastic potential energy of the spring can be consumed by the friction between the damping pad and the limit block. Twisting the torsion tube can change the position of the top plate, and then the shock absorbing performance can be adjusted by changing the compression state of the spring.
[0007] Preferably, a square rod is installed on the inner wall of the sleeve, and the outer wall of the square rod is movably connected to the limit block and the inner wall of the vertical rod in sequence. A sealing ring movably connected to the outer wall of the vertical rod is installed above the inner wall of the sleeve.

DETAILED DESCRIPTION
[0016] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process.
[0018] The cooperation of the first mounting frame, the second mounting frame, the shock absorbing mechanism and the adjusting mechanism can quickly and conveniently adjust the compression state of the spring when the spring is used for a long time and the contraction and expansion functions are weakened, so that the spring can be in the best use condition, thereby greatly extending the service life of the electric vehicle shock absorber, while also reducing the number of replacement times of the electric vehicle shock absorber, thereby facilitating the use of the staff;
[0019] In view of this, the utility model provides an electric vehicle shock absorber. When the current electric vehicle shock absorber is in use, due to long-term use, the shock-absorbing spring will inevitably lead to weakened contraction and expansion functions, and because the shock absorber does not have a shock-absorbing degree adjustment mechanism, it needs to be replaced, which makes the overall service life of the shock absorber shorter, increases the economic cost investment, and is more troublesome to replace, which brings inconvenience to the staff.
[0020] Embodiment 1: Figure 1 , 2, 3 and 4 show that an electric vehicle shock absorber comprises a first mounting frame 1, a second mounting frame 6 is arranged above the first mounting frame 1, and the electric vehicle shock absorber also comprises: a shock absorbing mechanism 2, arranged between the first mounting frame 1 and the second mounting frame 6; an adjusting mechanism 3, arranged above the shock absorbing mechanism 2; the shock absorbing mechanism 2 comprises: a sleeve 201, mounted on the top of the first mounting frame 1; a vertical rod 202, arranged above the sleeve 201; a limit block 203, mounted on the bottom of the vertical rod 202, and movably connected to the inner wall of the sleeve 201; a damping pad 204, mounted on the inner wall of the sleeve 201, and movably connected to the outer wall of the limit block 203; a spring 205, fixedly connected to the lower part of the outer wall of the sleeve 201, and extending to the upper part of the vertical rod 202; the adjusting mechanism 3 comprises: a torsion tube 30 1, is threadedly connected to the outer wall of the vertical rod 202; the top plate 302 is fixedly connected to the top of the spring 205 and is movably connected to the bottom of the torsion tube 301; the slider 303 is installed on the top of the top plate 302 and is slidably engaged with the inner wall of the torsion tube 301; wherein the shock absorbing mechanism 2 can realize the shock absorbing and buffering function, and the adjustment mechanism 3 can change the use state of the shock absorbing mechanism 2. When the vertical rod 202 moves along the inner wall of the sleeve 201, the spring 205 can be compressed so that the buffering work can be realized by the elastic force of the spring 205. The elastic potential energy of the spring 205 can be consumed by the friction between the damping pad 204 and the limit block 203. Twisting the torsion tube 301 can change the position of the top plate 302, and then the shock absorbing performance can be adjusted by changing the compression state of the spring 205;
[0021] In the specific implementation process, it is worth pointing out that the staff can use the first mounting frame 1 and the second mounting frame 6 to install the electric vehicle shock absorber on the external electric vehicle body. The shock absorbing mechanism 2 can automatically perform buffering and shock absorbing work when the electric vehicle passes through an uneven road surface, and the adjustment mechanism 3 can change the use state of the shock absorbing mechanism 2, so as to solve the problem that the shock absorbing effect decreases when the shock absorbing mechanism 2 ages. The limit block 203 can limit the sleeve 201 and the vertical rod 202. The friction between the damping pad 204 and the limit block 203 can consume the elastic potential energy of the spring 205, so that the spring 205 can be quickly stabilized. Twisting the torsion tube 301 can drive the top plate 302 to move, and then the compression state of the spring 205 can be changed through the top plate 302, and the slider 303 can limit the top plate 302 and the torsion tube 301.
[0022] Furthermore, a square rod 4 is installed on the inner wall of the sleeve 201, and the outer wall of the square rod 4 is movably connected to the limit block 203 and the inner wall of the vertical rod 202 in sequence. A sealing ring 5 movably connected to the outer wall of the vertical rod 202 is installed above the inner wall of the sleeve 201;
[0023] In the specific implementation process, it is worth pointing out that the square rod 4 can limit the vertical rod 202 and the sleeve 201, so that the vertical rod 202 can only achieve simple reciprocating motion on the inner wall of the sleeve 201, and the sealing ring 5 can improve the sealing performance between the vertical rod 202 and the sleeve 201, and can prevent external dust from entering the interior of the sleeve 201;
[0024] Furthermore, the outer wall of the twist tube 301 is processed with grinding lines, and the connection between the twist tube 301 and the top plate 302 is a smooth plane;
[0025] In the specific implementation process, it is worth pointing out that the collection of wear marks can make it easier for the staff to twist the twist tube 301, and the smooth surface design of the connection between the twist tube 301 and the top plate 302 can reduce the friction during rotation;
[0026] Specifically, when the electric vehicle shock absorber is used, the shock absorbing mechanism 2 can automatically perform shock absorption and buffering when the electric vehicle passes through an uneven road surface, thereby ensuring the comfort of people when riding, and the adjustment mechanism 3 can adjust the compression state of the spring 205 when the shock absorbing mechanism 2 is aged after long-term use, so that the shock absorbing mechanism 2 can be in the best use condition in real time. When buffering is performed, the vertical rod 202 drives the limit block 203 to move along the inner wall of the sleeve 201, and compresses the spring 205 at the same time. The elastic force of the spring 205 is used to achieve shock absorption and buffering operations. At the same time, the elastic potential energy of the spring 205 can be consumed through the friction between the limit block 203 and the damping pad 204, so that the spring 205 can be quickly stabilized. When the compression state of the spring 205 needs to be changed, the staff twists the torsion tube 301, and the torsion tube 301 can move along the outer wall of the vertical rod 202. At the same time, the compression state of the spring 205 can be changed through the top plate 302, so that the spring 205 can always be in the best use state.
