Description

Technical Field

[0001] This utility model relates to the field of shock absorber assembly technology, and in particular to a motorcycle shock absorber air and oil injection device. Background Technology

[0002] Motorcycle shock absorbers are the core components of a motorcycle suspension system, primarily used to cushion impacts from the ground, maintain vehicle stability, and improve riding comfort. They effectively absorb vibration energy through the combined action of springs and damping systems.

[0003] During the assembly process of motorcycle shock absorbers, an air-filling device or an oil-filling device is required to inflate or fill the shock absorbers. However, existing air-filling and oil-filling devices can only perform air-filling and oil-filling in isolation. Therefore, a motorcycle shock absorber air-filling and oil-filling device is proposed.

The piston can be driven to complete negative pressure suction and positive pressure feeding by simply controlling the electric telescopic rod through the control panel. There is no need to frequently change equipment, reducing assembly procedures and time costs.

[0019] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution: a motorcycle shock absorber inflation and oil injection device, including a turnover box 1, a stamping box 2 fixedly installed on the top of the turnover box 1, two threaded interfaces 3 provided on the top of the turnover box 1, and a gas cylinder 4 and an oil cylinder 5 respectively threadedly installed on the two threaded interfaces 3, a partition 13 fixedly installed on the inner wall of the turnover box 1, the partition 13 dividing the interior of the turnover box 1 into an air chamber and an oil chamber, a control panel 11 fixedly installed on the front outer wall of the stamping box 2, a constant pressure air hole 12 opened on the top of the stamping box 2, and also including an inflation and oil injection structure installed on the turnover box 1 and the stamping box 2, which is used to inflate and inject oil into the shock absorber through the turnover box 1, the stamping box 2 and the inflation and oil injection structure, and a connector 10 provided on the inflation and oil injection structure, which is used to connect the inflation and oil injection structure to the shock absorber.

[0021] Furthermore, the turnover box 1 has two piston chambers inside, which are arranged symmetrically on the left and right.

[0022] Furthermore, the inflation / oil injection structure includes a U-shaped connecting rod 6, a piston 7, a suction pipe 8, a hose 9, and an electric telescopic rod 15. The piston 7 is slidably installed inside the piston chamber. The U-shaped connecting rod 6 is fixedly installed on the top of the piston 7. The suction pipe 8 is fixedly installed on the top of the turnover box 1 and the bottom of the stamping box 2. The hose 9 is fixedly installed on the top of the turnover box 1 and one side of the turnover box 1, and the hose 9 passes through the bottom of the stamping box 2 and communicates with the piston chamber. When the electric telescopic rod 15 is activated, the free end of the electric telescopic rod 15 drives the U-shaped connecting rod 6 and the piston 7 to rise. The rise of the piston 7 creates a negative pressure in the piston chamber, allowing air / oil to enter the piston chamber through the suction pipe 8. When the electric telescopic rod 15 is activated, the free end of the electric telescopic rod 15 drives the U-shaped connecting rod 6 and the piston 7 to fall. The fall of the piston 7 creates a positive pressure in the piston chamber, allowing air / oil in the piston chamber to enter the shock absorber through the hose 9, thus inflating / injecting the shock absorber without the need for frequent equipment replacement, reducing assembly processes and time costs.

[0023] Furthermore, there are two pistons 7, two suction tubes 8, and two hoses 9 arranged symmetrically on the left and right, and both suction tubes 8 and hoses 9 are equipped with one-way valves.

[0024] Furthermore, the connector 10 is fitted onto one end of the hose 9, and the inner side of the connector 10 has an internal thread, which can be tightly connected with the air / oil port of the shock absorber to prevent media leakage.

[0025] Furthermore, two filters 14 are fixedly installed on the front and rear inner walls of the turnover box 1 to filter impurities from the gas and oil, ensuring the assembly quality of the shock absorber.

[0026] Furthermore, the front of the stamping box 2 is equipped with graduation lines, and the gas cylinder 4 and oil cylinder 5 are equipped with switch valves.

[0027] Working principle: Gas cylinder 4 and oil cylinder 5 are threaded into threaded interface 3. The valves on gas cylinder 4 and oil cylinder 5 are opened to allow gas / liquid to enter the gas / oil chamber of turnover box 1. Connector 10 is threaded into the air / oil inlet of the shock absorber, so that hose 9 is connected to the shock absorber. The electric telescopic rod 15 is activated through control panel 11. The free end of electric telescopic rod 15 drives U-shaped connecting rod 6 and piston 7 to rise. The rise of piston 7 creates negative pressure in piston chamber, allowing gas / oil to enter piston chamber through suction pipe 8. Control panel 11 is activated again. The free end of electric telescopic rod 15 drives U-shaped connecting rod 6 and piston 7 to fall. The fall of piston 7 creates positive pressure in piston chamber, allowing gas / oil in piston chamber to enter shock absorber through hose 9, thus inflating / injecting shock absorber.

[0028] 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.
