Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, and in particular to a reinforced automotive shock absorber. Background Technology

[0002] With the rapid development of the automotive industry, consumers are placing increasingly higher demands on vehicle performance and ride comfort. As a key component of the automotive suspension system, the performance of shock absorbers directly affects the vehicle's driving stability, handling, and ride comfort.

[0003] Traditional shock absorbers have significant drawbacks when faced with complex road conditions such as rugged mountain roads and potholes, as well as severe vibrations. Their damping mechanism is relatively simple and lacks the adaptive ability to automatically adjust the damping force according to the vibration intensity. In actual driving, when the top plate of the shock absorber drops to different heights due to vehicle bumps, it represents a dynamic change in vibration intensity. At this time, traditional shock absorbers cannot provide differentiated damping effects to match this, which affects the stability of the vehicle during driving and the passenger's riding experience. Therefore, we propose a reinforced automotive shock absorber. Utility Model Content

[0026] Please see Figure 1-4 This utility model provides a technical solution: a reinforced automotive shock absorber, comprising:

[0027] The shock absorber body includes a spring base 1, a shock absorber cylinder 2, a coil spring 3, and a spring upper seat 4. The shock absorber cylinder 2 is fixedly installed on the top of the spring base 1. The coil spring 3 is sleeved on the outside of the shock absorber cylinder 2. The telescopic end of the shock absorber cylinder 2 is fixedly connected to the spring upper seat 4. The top end of the coil spring 3 is fixedly connected to the spring upper seat 4. The bottom end of the coil spring 3 is fixedly connected to the spring base 1.

[0028] The damping auxiliary structure is located on the damper body.

[0029] The shock absorption auxiliary structure includes two first damping rods 10, two first springs 9, and two first positioning cylinders 8. The two first damping rods 10 are fixedly connected to the top of the spring base 1. The two first springs 9 are sleeved on the outer surface of the corresponding first damping rods 10. The telescopic ends of the two first damping rods 10 are fixedly connected to the mounting plates 15. The bottom ends of the two first springs 9 are fixedly connected to the corresponding first damping rods 10. The top ends of the two first springs 9 are fixedly connected to the corresponding mounting plates 15. The two first positioning cylinders 8 are fixedly connected to the bottom of the spring upper seat 4. The two mounting plates 15 are located inside the corresponding first positioning cylinders 8.

[0030] The damping auxiliary structure also includes two second damping rods 12, two second springs 11, and two second positioning cylinders 7. The two second damping rods 12 are fixedly connected to the top of the spring base 1. The two second springs 11 are sleeved on the outer surface of the corresponding second damping rods 12. The telescopic ends of the two second damping rods 12 are fixedly connected to the same mounting plate 15. The bottom ends of the two second springs 11 are fixedly connected to the corresponding second damping rods 12. The top ends of the two second springs 11 are fixedly connected to the corresponding mounting plates 15. The two second positioning cylinders 7 are fixedly connected to the bottom of the spring upper seat 4. The mounting plates 15 on the two second damping rods 12 are located inside the corresponding second positioning cylinders 7.

[0031] The top of each of the four mounting plates 15 is fixedly connected with a lower shock-absorbing pad 14, and the inner top walls of the two first positioning cylinders 8 and the two second positioning cylinders 7 are fixedly connected with an upper shock-absorbing pad 16.

[0032] The shock absorber body also includes a mounting column 5 and a fixing ear 6. The mounting column 5 is fixedly connected to the top of the spring seat 4, and the fixing ear 6 is fixedly connected to the outer surface of the mounting column 5. A dust scraper 13 is fixedly sleeved on the outer surface of the shock absorber cylinder 2, and the telescopic end of the shock absorber cylinder 2 is slidably connected to the inside of the dust scraper 13.

[0033] Furthermore, when using this device, when the shock absorber body is compressed and contracted, the upper spring seat 4 will compress the helical spring 3 and the shock absorber cylinder 2 to contract. As the upper spring seat 4 moves downward, it will simultaneously drive the two first positioning cylinders 8 and the two second positioning cylinders 7 to move downward synchronously. The downward movement of the two first positioning cylinders 8 will drive the upper damping pads 16 on them to move. Thus, when the upper spring seat 4 drives the two first positioning cylinders 8 to contact the tops of the two first damping rods 10, the upper damping pads 16 can contact the mounting plate 15 for buffering. Then, it will continue to drive the two first damping rods 10 and the two first springs 9 to contract, so that the two first damping rods 10 can perform auxiliary shock absorption with the cooperation of the first springs 9 on them. When the upper spring seat 4 continues to move downward and contacts the tops of the two second damping rods 12, the upper spring seat 4 will drive the two second damping rods 12 and the two second springs 11 to contract through the two second positioning cylinders 7, thereby facilitating further enhancement of the shock absorption effect.

[0034] With the cooperation of the first damping rod 10, the first spring 9, the first positioning cylinder 8, the second positioning cylinder 7, the second spring 11, and the second damping rod 12, the two first damping rods 10 can enhance the damping effect of the shock absorber body for the first time under the action of the first spring 9, and the two second damping rods 12 can further enhance the damping effect of the shock absorber body under the cooperation of the second spring 11. This allows the shock absorber body to adapt to the difference in vibration and further improve the performance of the shock absorber body.

[0035] Structural description: Second positioning cylinder 7: Fixedly connected to the bottom of the spring seat, providing guidance and limiting function for the mounting plate on the second damping rod. First positioning cylinder 8 is similar to second positioning cylinder 7, but corresponds to the combination of first damping rod and first spring.

[0036] The second spring 11 is sleeved on the outer surface of the corresponding second damping rod to provide shock absorption and enhance the shock absorption effect of the shock absorption auxiliary structure. The first spring 9 has the same function as the second spring 11, but corresponds to the first damping rod.

[0037] The second damping rod 12 is fixedly connected to the top of the spring base. Through telescopic movement, it works together with the mounting plate and the second spring to achieve the shock absorption effect. The first damping rod 10 and the second damping rod 12 have the same function.

[0038] Dust scraper 13: It is fixedly sleeved on the outer surface of the shock absorber cylinder to prevent dust and impurities from entering the inside of the shock absorber and protect the shock absorber to work normally;

[0039] Lower shock absorber 14: Fixedly connected to the top of the four mounting plates, it provides additional shock absorption and reduces the impact of vibration on the vehicle body;

[0040] Mounting plate 15: It is fixedly connected to the telescopic end of the damping rod, supports the top of the spring, and transmits the damping force to the positioning cylinder and the damping pad;

[0041] Upper shock-absorbing pad 16: Fixedly connected to the inner top wall of the positioning cylinder, it provides additional shock absorption and further enhances the shock absorption effect.

[0042] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
