Description
Technical Field
[0001] The utility model relates to the technical field of automobile shock absorbers, in particular to an automobile self-resetting shock absorber. Background Art
[0002] The application of shock absorbers is also everywhere, but conventional shock absorbers are basically only responsible for vibration reduction. With the development of the automobile industry, consumers have higher and higher requirements for automobiles. In order to quickly attenuate the vibration of the frame and body and improve the smoothness and comfort of the car's driving, shock absorbers are generally installed on the car suspension system. Shock absorbers are vulnerable parts during the use of the car. The quality of the shock absorber's structure will directly affect the stability of the car's driving and the life of other parts. Therefore, the shock absorber should always be in good working condition.
[0003] When the drive shaft of the shock absorber in the prior art rotates at high speed and the vehicle is bumpy, the outer ring will vibrate violently, which can easily damage the elastic connecting part, or the buffer spring may not provide sufficient buffering, resulting in a reduced life of the shock absorber or loss of function, or even separation of the outer ring and the inner ring. The high-speed rotating outer ring may collide with surrounding components, easily causing safety accidents. Utility Model Content

[0022] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.
[0023] like Figures 1 to 4 As shown, a self-resetting shock absorber for an automobile comprises a fixed sleeve 1, a sliding rod 2 which can slide is installed at the upper end of the fixed sleeve 1, a buffer spring 19 is sleeved on the surface of the fixed sleeve 1 and the sliding rod 2, the buffer spring 21 plays a protective role when the shock absorber is in use, and the shock absorber consumes the elastic potential energy of the buffer spring 21, mounting plates 20 are fixedly installed at both ends of the buffer spring 19, and a connecting ear 21 is fixedly installed at one end of the mounting plate 20, so that it is easy to be installed in the automobile for use through the connecting ear 21.
[0024] A frame 3 is fixedly installed at the lower end of the sliding rod 2, and the lower end of the frame 3 is fixedly connected to the horizontal plate 4. A transmission structure 5 is installed in the middle of the frame 3. The transmission structure 5 includes a rack 9, which is fixedly installed at one end of the frame 3. A vertical groove 10 is provided at the other end of the frame 3. A vertical plate 11 is installed inside the vertical groove 10. A rack 2 12 is installed at one end of the vertical plate 11. The positions of the rack 19 and the rack 2 12 are staggered with each other. A rotatable gear 13 is installed in the middle of the frame 3. The gear 13 is rotatably installed inside the fixed sleeve 1. The gear 13 is connected to the rack 9 and the rack The two 12 are meshed and connected, and sliding grooves 8 are provided on both sides of the fixed sleeve 1. The two ends of the frame 3 are slidably connected to the inside of the sliding grooves 8. When the shock absorber encounters vibration during operation, the mounting plate 20 compresses the buffer spring 19 and drives the sliding rod 2 to move downward. The sliding rod 2 drives the frame 3 to slide in the sliding groove 8, thereby driving the rack 19 to move downward, driving the gear 13 to rotate, and the rotation of the gear 13 drives the rack 2 12 to slide upward, thereby preventing the shock absorber from being suddenly subjected to excessive vibration amplitude, causing the sliding rod 2 to hit the inside of the fixed sleeve 1 and be damaged.
[0025] A frame 2 6 is fixedly installed at the bottom end of the fixed sleeve 1, and both ends of the frame 2 6 are slidably connected to the inside of the slide groove 8. The positions of the frame 1 3 and the frame 2 6 are staggered to avoid collision between the frame 1 3 and the frame 2 6 during sliding. A reset structure 7 is installed inside the frame 2 6 to restore the shock absorber to the state before vibration.
[0026] The reset structure 7 includes a connecting block 14 and a connecting block 15. The connecting block 14 is fixedly mounted on the lower end of the horizontal plate 4, and the connecting block 15 is fixedly mounted on the upper end of the frame 6. A support 16 is mounted on the lower end of the connecting block 14, and a support 2 17 is mounted on the upper end of the connecting block 15. A reset spring 18 is installed between the connecting block 14 and the connecting block 2 15, and both ends of the reset spring 18 are sleeved on the surface of the support 16 and the support 2 17.
[0027] When the frame 13 moves downward, the horizontal plate 4 is driven to move downward, and the vertical frame 11 is driven by the gear 13 and the rack 12 to move upward, so that the horizontal plate 4 drives the pillar 16 to move downward through the connecting block 14, and the vertical frame 11 drives the frame 2 6 to move upward, thereby driving the pillar 2 17 to move upward through the connecting block 2 15, thereby compressing the return spring 18. After the return spring 18 is compressed, it recovers under the elastic potential energy, so that the pillar 2 17 and the connecting block 2 15 move downward, and the pillar 1 16 and the connecting block 14 move upward, so that the frame 2 6 moves downward, the frame 13 moves upward, and the sliding rod 1 returns to its original position.
[0028] When in use, the shock absorber is installed in the car through the connecting ear 21. When the shock absorber encounters vibration during operation, the mounting plate 20 compresses the buffer spring 19 and drives the sliding rod 2 to move downward. The sliding rod 2 drives the frame 13 to slide in the slide groove 8, thereby driving the rack 19 to move downward, driving the gear 13 to rotate, and the rotation of the gear 13 drives the rack 2 12 to slide upward. When the frame 13 moves downward, the cross plate 4 moves downward. At the same time, the vertical frame 11 moves upward under the drive of the gear 13 and the rack 2 12, so that the cross plate 4 drives the pillar 16 to move downward through the connecting block 14, and the vertical frame 11 drives the frame 2 6 to move upward, thereby driving the pillar 2 17 to move upward through the connecting block 2 15, thereby compressing the reset spring 18. After the reset spring 18 is compressed, it recovers under the elastic potential energy, so that the pillar 2 17 and the connecting block 2 15 move downward, and the pillar 16 and the connecting block 14 move upward, so that the frame 2 6 moves downward, the frame 1 3 moves upward, and the sliding rod 1 returns to its original position.
[0029] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
