Description

Technical Field

[0001] This utility model relates to the field of shock absorber technology, specifically a shock absorber frame structure. Background Technology

[0002] Shock absorbers are crucial components of a car's chassis suspension system. When the car body and wheels vibrate, the fluid inside the shock absorber generates vibration resistance through friction as it flows through the damping orifices and through the fluid's viscous friction. This converts vibration energy into heat energy, which is then dissipated into the surrounding air, thus rapidly damping the vibration. Therefore, shock absorbers play a vital role in vehicle handling stability and ride comfort. Shock absorber bushings are the connecting parts between the shock absorber and the car body at both ends, and they need to have excellent wear resistance, damping capabilities, and compressive strength.

[0003] Currently, traditional shock absorber frames mostly adopt a single-layer cylindrical structure, which has problems such as stress concentration and poor lateral torsional resistance. At the same time, the bushings with frame structures on the market, including the outer tube and two separate inner frames set inside the outer tube, have vertical displacement problems, which can cause them to detach from the frame and pose serious driving safety hazards. Therefore, we propose a shock absorber frame structure to solve the above problems. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example

[0023] like Figures 1-3 As shown, an embodiment of the present invention provides a shock absorber frame structure, including a frame body 1. Connectors 2 are fixedly installed on the upper and lower sides of the frame body 1. A protective mechanism 3 is sleeved between the outer surfaces of the frame body 1 and the upper and lower connectors 2. The protective mechanism 3 is connected and fixed to the upper and lower connectors 2 through a limiting mechanism 4.

[0024] like Figure 3 As shown, in some embodiments, the main body 1 of the skeleton includes a polyurethane damping bushing 101, a reinforcing layer 102 and a steel strip layer 103. The reinforcing layer 102 is fixedly installed on the outer surface of the polyurethane damping bushing 101, and the steel strip layer 103 is spirally wound on the outer surface of the reinforcing layer 102.

[0025] In this embodiment, the polyurethane damping bushing 101 can suppress low-frequency resonance, the reinforcing layer 102 disperses the transverse prestress, and the steel strip layer 103 absorbs high-frequency vibration through deformation.

[0026] like Figure 3 As shown, in some embodiments, the reinforcing layer 102 adopts a 3D-printed titanium alloy mesh structure, and the steel strip layer 103 adopts a high-carbon steel strip with a thickness of 1.2-1.8mm and a helix angle of 30°-45°.

[0027] In this embodiment, the reinforcing layer 102 has greater structural strength and better lateral prestress dispersion effect, while the steel strip layer 103 has better vibration damping effect.

[0028] like Figure 2 As shown, in some embodiments, the protective mechanism 3 includes a metal sleeve 301 and an elastic rubber sleeve 302. Two metal sleeves 301 are provided on the upper and lower sides, and an elastic rubber sleeve 302 is fixedly installed between the upper and lower metal sleeves 301. The metal sleeve 301 and the elastic rubber sleeve 302 are movably sleeved on the outer surface of the skeleton body 1.

[0029] In this embodiment, the upper and lower metal sleeves 301 can prevent the frame body 1 from deforming and being damaged from the left and right sides. The elastic rubber sleeves 302 enable the upper and lower metal sleeves 301 to have the function of vertical extension and retraction, which meets the deformation requirements of the frame body 1 and increases the buffering and shock absorption function.

[0030] like Figure 2 As shown, in some embodiments, the limiting mechanism 4 includes a mounting groove 401, a spring 402, a limiting post 403, a limiting groove 404, a pull rod 405, and a handle 406. Mounting grooves 401 are provided on both the left and right inner walls of the metal sleeve 301. A spring 402 is fixedly installed in the mounting groove 401, and a limiting post 403 is fixedly installed on the side of the spring 402 facing the connector 2. A limiting groove 404 is provided on the connector 2 corresponding to the limiting post 403. The limiting post 403 is movably inserted into the limiting groove 404. A pull rod 405 is fixedly installed on the side of the limiting post 403 away from the connector 2. A handle 406 is fixedly installed on the end of the pull rod 405 located on the outer side of the metal sleeve 301.

[0031] In this embodiment, the spring 402 pushes the limiting post 403 to be inserted into the limiting groove 404 on the connector 2, thereby achieving the effect of limiting and fixing the metal sleeve 301 and the connector 2. This allows the upper and lower metal sleeves 301 and the elastic rubber sleeve 302 to be fitted onto the outer surface of the frame body 1. By pulling the handle 406 away from the metal sleeve 301, the handle 406 pulls the limiting post 403 out of the limiting groove 404 via the pull rod 405, thereby separating the metal sleeve 301 from the connector 2 and facilitating the disassembly of the upper and lower metal sleeves 301 and the elastic rubber sleeve 302.

[0032] like Figure 2 As shown, in some embodiments, a through hole 5 is provided on the metal sleeve 301 corresponding to the pull rod 405, and the diameter of the through hole 5 is smaller than the diameter of the handle 406.

[0033] In this embodiment, the through hole 5 meets the requirements for the left and right movement of the pull rod 405, and the handle 406 will not retract into the through hole 5.

[0034] In use, the polyurethane damping bushing 101 in the main frame 1 suppresses low-frequency resonance, the reinforcing layer 102 disperses lateral prestress, and the steel strip layer 103 absorbs high-frequency vibration through deformation. This gives the frame structure good functions of dispersing prestress and lateral torsional resistance, making it stronger and less prone to damage. The upper and lower metal sleeves 301 and elastic rubber sleeves 302 in the protective mechanism 3 are fitted onto the outer surface of the main frame 1. The spring 402 in the limiting mechanism 4 pushes the limiting post 403 into the limiting groove 404 on the connector 2, achieving the effect of limiting and fixing the metal sleeves 301 and the connector 2. This increases the protective function of the upper and lower metal sleeves 301 on the main frame 1 and the upper and lower connectors 2, and prevents them from detaching from the main frame 1. The elastic rubber sleeves 302 increase the buffering function between the upper and lower metal sleeves 301, which increases the buffering and shock absorption function of the main frame 1, making it easier to use.

[0035] In summary, the shock absorber frame structure enables the frame body 1 to have better functions of dispersing prestress and lateral torsional resistance, making it stronger and less prone to damage. Furthermore, the outer protective mechanism 3 enhances the protection of the frame body 1. The protective mechanism 3 will not detach from the frame body 1, and at the same time, the protective mechanism 3 increases its own buffering function with the frame body 1, which is beneficial to use.
