Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to a coil for an electromagnetic shock absorber. Background Art

[0002] Shock absorbers are generally used to suppress the impact and road surface caused by the spring's recovery after shock absorption. Nowadays, they can be widely used in automobiles to reduce the bumps caused by riding by accelerating the shock absorption of the frame and body. When driving a car over uneven ground, the spring can filter the vibration from the road surface, but due to the large amplitude of reciprocating motion, shock absorbers are also needed to control the jump of the spring.

[0003] However, the shock absorber cannot be adjusted during use, resulting in that most existing electromagnetic shock absorbers cannot be adjusted according to the needs of the car, resulting in a limited range of shock absorption for the shock absorber. The utility model patent "An adjustable vehicle shock absorber" with the authorization announcement number CN220134497U proposes a shock absorber that can adjust the shock absorption performance by changing the valve flow to improve the driver's driving comfort. However, for ground conditions with larger potholes or gullies, the reciprocating motion of the shock absorber is too large, which will cause huge bumps. Utility Model Content

[0004] In order to solve at least one of the technical problems mentioned in the background technology, the purpose of the utility model is to provide a coil for an electromagnetic shock absorber, which can adjust the length of the shock absorber to control the distance between the two ends of the shock absorber, thereby adjusting the rebound distance of the reciprocating motion of the shock absorber.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A coil for an electromagnetic shock absorber comprises a connecting shell, a shock absorbing coil mounted on the connecting shell and a shock absorber body, wherein the shock absorbing coil is provided with a shock absorbing assembly, the shock absorbing assembly comprises a connector fixedly connected to the shock absorbing coil, a telescopic rod is fixedly connected to the connector, one end of a shock absorbing extension block is slidably connected to the telescopic rod along the height direction of the connecting shell, and a shock absorbing assembly for driving the shock absorbing extension block to move is provided in the connecting shell.

[0007] Furthermore, the other end of the shock-absorbing extension block is fixedly connected to a connecting block, and the shock-absorbing assembly includes a spring pneumatic rod fixedly connected to the connecting block, and the other end of the spring pneumatic rod is fixedly connected to the connecting block.

[0008] Furthermore, a cavity is provided inside the shock absorber body, and an electromagnetic fluid cavity is provided inside the shock absorbing extension block.

[0009] Furthermore, the shock absorbing assembly also includes an oil plug fixedly connected to the cavity, a push head fixedly connected to the free end of the oil plug, and the push head is slidably connected to the electromagnetic fluid cavity.

[0010] Furthermore, a liquid storage chamber connected to the electromagnetic liquid chamber is provided in the shock-absorbing extension block, and a liquid replacement valve is provided at the bottom of the electromagnetic liquid chamber.

[0011] Furthermore, an air pump for driving the spring pneumatic rod to extend is provided in the connecting block.

[0012] Compared with the prior art, the utility model has the beneficial effect that the utility model can freely change the length of the shock absorber under the premise of alleviating the bumps, so as to achieve the effect of reducing the rebound distance, thereby reducing the bumps generated by the vehicle body as much as possible.

DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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.

[0018] See also Figure 1 , Figure 2 and Figure 3The present embodiment provides a coil for an electromagnetic shock absorber, comprising a connecting shell 11, a shock absorbing coil 12 installed on the connecting shell 11, and a shock absorber body 13, wherein the shock absorbing coil 12 is provided with a shock absorbing assembly 24, wherein the shock absorbing assembly 24 comprises a connector 14 fixedly connected to the shock absorbing coil 12, wherein the connector 14 is fixedly connected with a telescopic rod 15, wherein one end of a shock absorbing insertion block 16 is slidably connected to the telescopic rod 15 along the height direction of the connecting shell 11, and wherein the connecting shell 11 is provided with a shock absorbing assembly 24 for driving the shock absorbing insertion block 16 to move.

[0019] The shock absorbing assembly 24 further includes an oil plug 19 fixedly connected to the cavity 18 , a push head 20 is fixedly connected to the free end of the oil plug 19 , and the push head 20 is slidably connected to the electromagnetic fluid chamber 21 .

[0020] Since the exterior of the shock absorber body 13 is of a corrugated design, it can be stretched and retracted through the shock absorbing assembly 24, so as to perform shock absorbing treatment on the vehicle body, and through the connection between the connector 14 and the shock absorbing coil 12, the shock absorbing coil 12 can alleviate the bumps from both ends.

[0021] A liquid storage chamber 22 communicating with the electromagnetic liquid chamber 21 is disposed in the shock-absorbing extension block 16 , and a liquid replacement valve 23 is disposed at the bottom of the electromagnetic liquid chamber 21 .

[0022] During use, there are two shock absorption methods. One is the conventional shock absorption through the shock absorbing coil 12, and the other is to relieve the pressure through the electromagnetic fluid in the electromagnetic fluid chamber 21. When the shock absorbing extension block 16 is pressed to move into the cavity 18, the push head will move into the electromagnetic fluid chamber 21. Subsequently, the electromagnetic fluid in the electromagnetic fluid chamber 21 will be squeezed into the liquid storage chamber 22 to ensure the integrity of the internal electromagnetic fluid.

[0023] The other end of the shock-absorbing extension block 16 is fixedly connected to a connecting block 17 . The shock-absorbing assembly 24 includes a spring pneumatic rod 26 fixedly connected to the connecting block 17 . The other end of the spring pneumatic rod 26 is fixedly connected to the connecting block 17 .

[0024] An air pump for driving the spring pneumatic rod 26 to extend is disposed in the connecting block 17 .

[0025] When only the spring is used for shock absorption, the length can be adjusted by the spring pneumatic rod 26 to achieve extension, thereby extending the distance that the shock absorbing extension block 16 is inserted into the cavity 18, making the shock absorber body 13 longer as a whole and reducing the distance required for reciprocation. When electromagnetic fluid shock absorption is required, the air pump is turned off.

[0026] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.
