Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an electromagnet adjustable shock absorber. Background Art

[0002] Shock absorbers are used to suppress the shock caused by the rebound of springs after absorbing shock and the impact from the road surface. They are widely used in automobiles to accelerate the attenuation of frame and body vibrations to improve the ride smoothness of the car. When passing through uneven roads, although the shock-absorbing spring can filter the vibration of the road surface, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump.

[0003] Most of the existing shock absorbers use springs to achieve shock absorption. Although they are widely used, they still have obvious defects in actual use, such as:

[0004] The existing spring shock absorber has an obvious shock absorption limit. When encountering a shock absorption situation, it can only passively absorb shock and cannot be adjusted according to its own weight bearing capacity. Therefore, the spring shock absorber often bottoms out. In addition, it has high friction and slow response speed during use. Long-term use can easily cause damage to itself and affect its service life.

[0005] Therefore now design can be adjusted a kind of electromagnet adjustable shock absorber to solve this type of defect. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides an electromagnet adjustable shock absorber, which solves the problem that the prior spring shock absorber is easy to bottom out and has large friction.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: an electromagnet adjustable shock absorber, comprising a shock absorber cylinder, a sealing guide cover is installed on the top of the shock absorber cylinder, a first electromagnet is fixedly connected to the bottom of the sealing guide cover and located on the inner side of the shock absorber cylinder, a second electromagnet is fixedly connected to the bottom of the inner cavity of the shock absorber cylinder, the top of the sealing guide cover is fixedly connected to a guide cylinder used in conjunction with the first electromagnet through an opening, a shock absorber rod is slidably installed on the inner side of the guide cylinder, and the bottom end of the shock absorber rod passes through the first electromagnet and extends to the inner side of the shock absorber cylinder, one end of the shock absorber rod extending to the inner side of the shock absorber cylinder is fixedly connected to a third electromagnet, and the third electromagnet is located between the first electromagnet and the second electromagnet.

[0008] Preferably, guide grooves are provided on both sides, the front and the rear of the inner cavity of the shock absorber cylinder, a guide slider is slidably installed on the inner side of the guide groove, and a fourth electromagnet is fixedly connected between the four guide sliders.

[0009] Preferably, the top and the bottom of the fourth electromagnet are fixedly connected with rubber rings used in conjunction with the third electromagnet and the second electromagnet.

[0010] Preferably, a wire embedding frame is fixedly mounted on the surface of the shock absorbing cylinder. Beneficial Effects

[0011] The utility model provides an electromagnetic adjustable shock absorber. Compared with the existing technology, it has the following beneficial effects:

[0012] (1) The electromagnet adjustable shock absorber has a first electromagnet, a second electromagnet, a third electromagnet and a fourth electromagnet arranged inside the shock absorber cylinder. The arrangement of these structures can change its own magnetism according to different road surfaces by transmitting electric current to them to different degrees, so that the distance between the third electromagnet, the second electromagnet and the first electromagnet can be adjusted in time to avoid bottoming out. The device has strong environmental adaptability, low sealing requirements, fast response speed, long service life and good shock absorption effect.

[0013] (2) The electromagnet adjustable shock absorber is used by arranging a fourth electromagnet inside the shock absorber cylinder, and installing rubber rings on the top and bottom of the fourth electromagnet respectively, and using it in conjunction with a guide slider. The arrangement of these structures can use the rubber ring to block the first electromagnet and the second electromagnet after the device is powered off, so as to avoid direct descent and hard contact that may cause damage, thereby protecting the device and meeting the current use requirements.
