Description

Technical Field

[0001] The utility model relates to the technical field of simulation vehicle transmission, in particular to a shock absorber for a model vehicle. Background Technique

[0002] A simulation vehicle is a kind of game vehicle, which is used to provide players with a feeling of driving a real-life car. In simulation climbing vehicles, the posture of the vehicle when driving on bumpy roads has always troubled model enthusiasts. At present, most of the climbing vehicle shock absorber cylinders in the market are large, with a short stroke and adopt screw technology. While this shock absorber has a small shock absorber cylinder, a long stroke, a light weight, and uses welding technology to make the shock absorber structure more concise and practical. The shock absorber structure of the model vehicle is composed of a piston, a shock absorber cylinder, a piston rod, and an oil seal. The main function of the shock absorber is to absorb the impact and vibration generated during the driving of the vehicle. Inevitably, when the vehicle is driving, it will encounter uneven roads, potholes, obstacles, etc., which will bring impact and vibration to the vehicle. If these impacts and vibrations cannot be effectively eliminated, it will pose a serious threat to the driving stability and safety of the vehicle. The role of the shock absorber is to absorb its energy through damping when the vehicle passes through or an impact occurs, thereby reducing the impact and vibration on the vehicle, making the body more stable, and improving the driving safety and stability. The utility model has a simple and reasonable structure, a light weight, good shock absorption effect when the vehicle is driving on bumpy roads or flat roads, a relatively fast reset speed of the piston valve assembly, and a long service life.

The lower end of the shock absorber cylinder is connected to a lower shock absorber cover by thread. The inner wall of the lower shock absorber cover is connected to an adjusting ring through a snap ring B. A piston rod guide sleeve is pressed against the inner sides of the adjusting ring and the lower shock absorber cover. The inner wall of the piston rod guide sleeve is attached to the piston rod through an O-ring A. And the other end of the piston rod is connected to a shock wave angle by thread.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0017] The present utility model will be further described below with reference to the accompanying drawings:

[0018] Refer to the attached Figures 1-4: In this embodiment, a shock absorber for a model car includes a shock absorber upper cover 1 and a shock absorber cylinder 3. A piston rod 7 is provided on the inner wall of the shock absorber cylinder 3. One end of the piston rod 7 is connected to a piston 6 through a snap ring A 5. The outer wall of the piston 6 fits against the inner wall of the shock absorber cylinder 3. The piston 6 can move on the inner wall of the shock absorber cylinder 3. Small through holes are machined on the surface of the piston 6. When a large impact occurs, the piston 6 will cause a pressure change on the inner wall of the shock absorber cylinder 3 to achieve buffering, and the small through holes on the surface of the piston 6 are used to restore the internal pressure balance of the shock absorber cylinder 3. The lower end of the shock absorber cylinder 3 is threadedly connected to a shock absorber lower cover 13. The inner wall of the shock absorber lower cover 13 is connected to an adjusting ring 10 through a snap ring B 8. A piston rod guide sleeve 11 is tightly pressed against the inner sides of the adjusting ring 10 and the shock absorber lower cover 13. The inner wall of the piston rod guide sleeve 11 fits against the piston rod 7 through an O-ring A 9. The other end of the piston rod 7 is threadedly connected to a shock wave angle 14. A spring support 16 is sleeved above the shock wave angle 14. A return spring 15 is provided above the spring support 16. The elastic coefficient of the return spring 15 can be determined according to specific usage conditions. The two sides of the return spring 15 are fixedly connected to the spring support 16 and a spring adjusting ring 4 respectively.

[0019] Refer to the appendix Figures 1-4 : In this embodiment, the spring adjusting ring 4 is fixedly machined on the lower part of the outer wall of the shock absorber cylinder 3. An O-ring B 12 is tightly pressed against the joint between the shock absorber lower cover 13 and the shock absorber cylinder 3. The notched parts of the shock absorber upper cover 1 and the shock wave angle 14 are both connected to a ball head bead 2 through rubber rings. After the ball head bead 2 is connected to the outside, the ball head bead 2 can rotate within a certain range between the shock absorber upper cover 1 and the shock wave angle 14 (that is, the shock absorber upper cover 1 and the shock wave angle 14 can rotate through the ball head bead 2 with the outside connection part), and it is ensured that the ball head bead 2 is always inside the shock absorber upper cover 1 and the shock wave angle 14 during the rotation process to achieve shock buffering at different angles. The outer wall end of the shock absorber cylinder 3 is fixedly connected to the shock absorber upper cover 1.

[0020] Through the cooperation among the shock absorber cylinder 3, the spring adjusting ring 4, the piston 6, the piston rod 7, the spring support 16 and the return spring 15, when the vehicle is driving on a bumpy road section or a flat road surface, the buffering and shock absorption are achieved by using the self-elasticity of the return spring 15 and the medium pressure change of the piston 6 on the inner wall of the shock absorber cylinder 3. The shock absorption effect is good, the piston valve assembly has a fast reset speed, the structure is simple, and it is easy to disassemble and assemble, providing convenience for model enthusiasts who love climbing cars.

[0021] Working principle:

[0022] When this model car shock absorber is needed for use, first insert the piston 6 into the piston rod 7 and fix it with snap ring A5. The piston rod guide sleeve 11, O-ring A 9, adjusting ring 10 and the assembled piston rod 7 are respectively installed into the shock absorber lower cover 13 in sequence and fixed with snap ring B 8. The O-ring B12 is assembled with the shock absorber lower cover 13. The shock absorber upper cover 1, shock absorber cylinder 3 and spring adjusting ring 4 are connected into one body by welding technology. The shock absorber lower cover 13 and the shock absorber cylinder 3 are assembled. The shock wave angle 14 is assembled with the piston rod 7. The ball head beads 2 are respectively installed into the shock absorber upper cover 1 and the shock wave angle 14 and fixed with O-ring rubber. The return spring 15 is inserted into the shock absorber cylinder 3 from the bottom, and the spring support 16 is installed on the shock wave angle 14 to fix the return spring 15, thus completing the installation of the shock absorber. The shock absorber of the present utility model enables the vehicle to achieve buffering and shock absorption by utilizing the self-elasticity of the return spring 15 and the change of the medium pressure of the piston 6 on the inner wall of the shock absorber cylinder 3 when driving on bumpy roads or flat roads. The shock absorption effect is good, the piston valve assembly returns quickly, the structure is simple, and it is easy to disassemble and assemble, providing convenience for the vast number of model enthusiasts who love climbing cars.
