[0002] Shock absorber is a common term in the automotive chassis industry. In fact, a car shock absorber is a vibration damper. Shock absorbers are not only used in the suspension of cars, but also in other places. For example, they are used in the cab, seats, steering wheels, etc. They can also be used as buffers on vehicle bumpers. In the suspension system, the elastic elements are subjected to impact and vibrations. In order to improve the smoothness of the car's ride, shock absorbers are installed in parallel with the elastic elements in the suspension. In order to attenuate the vibrations, the shock absorbers used in the automobile suspension system are mostly hydraulic shock absorbers.

[0009] Preferably, sliding grooves are provided inside the two scraping plates, and the cross-sections of the two scraping plates are both semicircular, so that the sliding plates can fit the inside of the connecting shell easily.

[0010] Preferably, the two sliding grooves are both slidably connected with sliding blocks, and the tops of the two sliding blocks are both fixedly connected with scraping rods, so that the sliding blocks can drive the scraping rods to rotate.

[0011] Preferably, the outer surfaces of the two scraping rods are in contact with the inner wall of the connecting shell, and the outsides of the two sliding blocks are fixedly connected with sliding scrapers, which can facilitate the sliding of the sliding scrapers.

[0012] Preferably, the bottom of the two sliding scrapers are respectively in contact with the top of the two scraping plates, and an auxiliary mechanism is provided at the bottom of the shock absorber body. The auxiliary mechanism includes multiple mounting plates, and the multiple mounting plates are fixedly mounted on the bottom of the shock absorber body and can be fixedly connected to the mounting plates.

[0013] Preferably, a plurality of the mounting plates are fixedly connected inside with fixed connecting plates, and the plurality of the fixed connecting plates are all configured to be L-shaped, which can facilitate fixed connection of the fixed connecting plates.

[0018] The present invention provides a magnetoelectric reaction type variable damping shock absorber, which has the following beneficial effects:

[0019] 1. The magneto-electric reactive variable damping shock absorber has a blocking mechanism designed so that the built-in oil will flow out of the shock absorber body after it is damaged. At this time, the leaked oil will be blocked and collected by the connecting shell, thereby preventing the leaked oil from sliding to the ground.

[0020] 2. The magneto-electric reactive variable damping shock absorber has a blocking mechanism design.

[0021] 3. The magneto-electric reactive variable damping shock absorber, through the design of the auxiliary mechanism, because the buffer spring will indirectly drive the force ring to sink rapidly during the process of rapid stretching and resetting, the elastic spring will no longer be subjected to the upward squeezing force, and then the force plate will rotate rapidly and collide with the harmonic plate, thereby achieving the effect of frequently hitting the harmonic plate for harmonics, so that the driver of the vehicle can quickly hear the abnormal noise, which is convenient for timely inspection and maintenance of the vehicle to prevent the gradual increase of vehicle damage.

[0022] 4. The magneto-electric reactive variable damping shock absorber is designed with a blocking mechanism and an auxiliary mechanism. When the tire structure drives the connecting shell to descend, the end cover will leave the force ring, so that the auxiliary mechanism can temporarily reduce the vibration of the vehicle after the shock absorber body is damaged, avoiding the wear of the chassis due to a sharp decline in the vehicle's vibration reduction effect after the oil inside the shock absorber body flows out, thereby reducing the cost of vehicle repair.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0034] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0035] See also Figure 1-5 The present invention provides a technical solution: a magnetoelectric reaction type variable damping shock absorber, comprising a shock absorber body 1, a shock absorber spring 2 is fixedly connected inside the shock absorber body 1, a piston rod 3 is slidably connected inside the shock absorber body 1, and a blocking mechanism 4 is provided outside the shock absorber body 1;

[0036] The blocking mechanism 4 comprises:

[0037] A connecting shell 401 is fixedly connected to the outside of the piston rod 3, an end cover 402 is fixedly connected to the inside of the connecting shell 401, the outer surface of the end cover 402 is in contact with the inside of the shock absorber body 1, and movable doors 403 are provided on both sides of the top of the end cover 402. The two movable doors 403 are movably connected to the end cover 402 through a rotating shaft, so that the movable doors 403 can rotate;

[0038] Two scraping plates 404 are provided at the bottom of the inner cavity of the connecting shell 401 , and both scraping plates 404 are in contact with the inside of the connecting shell 401 , so that the scraping plates 404 will slide downward when the connecting shell 401 is tilted or inverted.

[0039] When in use, the staff first needs to load the shock absorber body 1 on the bottom of the vehicle, and then connect the piston rod 3 to the wheel structure. If the car is driving on a stable road, the tire will not move violently, so the piston rod 3 will not move much. If the car is driving on a bumpy road, the tire will jump up and down quickly due to the unevenness of the road, and then the tire structure will drive the piston rod 3 to move telescopically. At this time, the piston rod 3 will perform hydraulic work inside the shock absorber body 1, and the shock absorbing spring 2 will also be stretched or compressed after being subjected to force.

[0040] If the vehicle is used for too long or the driver drives the vehicle improperly and encounters a bumpy road, the shock absorber body 1 is likely to be damaged due to aging. The built-in oil will flow out of the shock absorber body 1 after damage, so the leaked oil will be blocked and collected by the connecting shell 401 at this time, thereby preventing the leaked oil from sliding to the ground. On the one hand, it can avoid the difficulty in recovering the oil, and on the other hand, it can avoid the dirtiness of the road environment and the need for manual cleaning, thereby ensuring the road environment.

[0041] See also Figure 1-9 , sliding grooves are provided inside the two scraping plates 404, and the cross-sections of the two scraping plates 404 are both set to be semicircular, and the sliding blocks 405 are slidably connected inside the two sliding grooves, and the tops of the two sliding blocks 405 are fixedly connected with the scraping rod bodies 406, and the outer surfaces of the two scraping rod bodies 406 are in contact with the inner wall of the connecting shell 401, and the sliding scrapers 407 are fixedly connected to the outside of the two sliding blocks 405, and the bottoms of the two sliding scrapers 407 are in contact with the tops of the two scraping plates 404 respectively, and the bottom of the shock absorber body 1 is provided with an auxiliary mechanism 5, and the auxiliary mechanism 5 includes a plurality of mounting plates 501, and the plurality of mounting plates 501 are fixedly installed at the bottom of the shock absorber body 1;

[0042] A plurality of mounting plates 501 are fixedly connected inside with fixed connecting plates 502, and the plurality of fixed connecting plates 502 are all set to be L-shaped. The outer ends of the plurality of fixed connecting plates 502 are fixedly connected with load-bearing buffer plates 503, and the plurality of load-bearing buffer plates 503 are all set to be arc-shaped. The plurality of load-bearing buffer plates 503 are fixedly connected inside with buffer springs 504, and the tops of the plurality of buffer springs 504 are respectively fixedly connected to the bottoms of the plurality of fixed connecting plates 502, and the bottoms of the plurality of load-bearing buffer plates 503 are fixedly connected with force rings 505;

[0043] A fixed outer plate 506 is fixedly connected to the outside of the shock absorber body 1, and a plurality of groups of clamping plates 507 are fixedly connected to the top of the fixed outer plate 506, and the number of the plurality of clamping plates 507 is two. A rotating shaft 508 is rotatably connected between the plurality of clamping plates 507, and the plurality of rotating shafts 508 are fixedly connected to the outside of the force-bearing plates 509, and the tops of the plurality of force-bearing plates 509 are fixedly connected to elastic springs 510, and the tops of the plurality of elastic springs 510 are fixedly connected to auxiliary plates 511, and the bottoms of the plurality of auxiliary plates 511 are fixedly connected to the top of the fixed outer plate 506, and a plurality of overtone plates 512 are fixedly connected to the outside of the fixed outer plate 506, and a plurality of guide rods 513 are fixedly connected to the top of the force ring 505.

[0044] If the driver does not stop driving while the vehicle is in motion, the shock absorption effect will be greatly reduced due to the leakage of oil in the shock absorber body 1. Therefore, if the vehicle is still driving on a bumpy road, the shock absorber body 1 and the vehicle chassis will be greatly worn due to the poor shock absorption effect. At this time, the vehicle will still drive the piston rod 3 to move up and down during the up and down bumping process. The piston rod 3 will drive the connecting shell 401 to rise during the upward movement. The connecting shell 401 will drive the end cover 402 to move upward synchronously when it rises. When the end cover 402 and the bottom of the force ring 505 are When the tire structure drives the connecting shell 401 to descend, the end cover 402 will leave the stress ring 505, so that the auxiliary mechanism 5 can temporarily reduce the vibration of the vehicle after the shock absorber body 1 is damaged, and the oil inside the shock absorber body 1 will not flow out, so as to avoid the wear of the chassis due to the sharp decline in the vibration reduction effect of the vehicle, thereby reducing the cost of vehicle repair;

[0045] In the above working process, the auxiliary mechanism 5 can not only perform temporary vibration reduction work on the vehicle, but also enable the owner to find the abnormal phenomenon of uneven vibration reduction effect when the vehicle passes through bumpy roads according to the usual driving habits, and find a vehicle repair shop for repair in time to reduce the repair cost;

[0046] At the same time, since the force ring 505 will synchronously drive the guide rod 513 to move upward during the rising process, the guide rod 513 will contact the force plate 509 during the rising process and drive the force plate 509 to rotate upward. During the rotation process, the force plate 509 will synchronously drive the elastic spring 510 to be compressed. Since the buffer spring 504 will indirectly drive the force ring 505 to sink rapidly during the rapid stretching and resetting process, the elastic spring 510 will no longer be subjected to the upward squeezing force. Then the elastic spring 510 will be rapidly stretched and reset. Then the force plate 509 will rotate rapidly and collide with the harmonic plate 512, so as to achieve the working effect of frequently hitting the harmonic plate 512 for harmonic generation, so that the person driving the vehicle can quickly hear the abnormal sound, which is convenient for timely finding a point to repair the vehicle and preventing the vehicle damage from gradually increasing.

[0047] When the vehicle enters the auto repair shop, the maintenance personnel will disassemble the shock absorber body 1, then tilt the shock absorber body 1, with the piston rod 3 facing the sky and the end cover 402 facing the ground. At this time, the end cover 402 will be rotated and opened by tilting, and then the oil leaking from the shock absorber body 1 will tilt out from the inside of the connecting shell 401. At the same time, the scraper plate 404 will scrape the oil on the inner wall. When the maintenance personnel rotate the connecting shell 401 back and forth along the ground, the sliding block 405 will drive the scraper rod 406 and the sliding scraper plate 407 to scrape and clean the inside of the shock absorber body 1, thereby achieving the effect of quickly attracting and flowing the oil, and avoiding the phenomenon of unclean flow and slow flow rate of the oil during the circulation process.
