Description

Technical Field

[0001] The utility model relates to the technical field of shock absorbers, in particular to an electric control shock absorber structure. Background Art

[0002] The electronically controlled shock absorber is a new type of shock absorber that uses solenoid valve technology. The core component of the electronically controlled shock absorber is the solenoid valve. Traditional mechanical shock absorbers can usually only be adjusted according to the preset damping coefficient, while the electronically controlled shock absorber can achieve fine adjustment and optimization of the shock absorber through the control of the solenoid valve, so that the electronically controlled shock absorber has higher precision and controllability, and can achieve fine adjustment of the vehicle's shock absorbing effect, which can effectively improve the vehicle's stability and handling, thereby further improving the vehicle's ride comfort and safety.

[0003] At present, one end of the link ring of the electronically controlled shock absorber is inserted into the flange hole of the intermediate cylinder and sealed by an O-ring, and the other end is tightened by a solenoid valve to ensure that it does not shake during operation. The clamping force is fully transmitted to the intermediate cylinder. The intermediate cylinder is subjected to a large lateral force, and the connection position between the link ring and the intermediate cylinder is easy to loosen, resulting in abnormal noise and other problems during operation, which affects the performance of the electronically controlled shock absorber. Utility Model Content

[0004] The technical problem to be solved by the utility model is how to prevent the connection position between the link ring and the intermediate cylinder from being loosened so as to improve the performance of the electronically controlled shock absorber.

[0005] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0006] An electronically controlled shock absorber structure comprises a working cylinder, an intermediate cylinder, an oil storage cylinder, a valve seat, a solenoid valve and a linking ring, wherein the intermediate cylinder and the oil storage cylinder are sequentially sleeved on the outer side of the working cylinder, a first cavity is formed between the intermediate cylinder and the working cylinder, a second cavity is formed between the intermediate cylinder and the oil storage cylinder, the valve seat is fixed to the outer wall of the oil storage cylinder, a solenoid valve is arranged in the valve seat, one end of the linking ring is sealingly clamped on the intermediate cylinder, and the other end of the linking ring is confined between the solenoid valve and the outer wall of the oil storage cylinder, so that the first cavity is connected to the solenoid valve through the linking ring.

[0007] The electromagnetic valve is abutted on the overlapping platform, and one end of the link ring is confined between the electromagnetic valve and the outer wall of the oil storage cylinder. The assembly is simple and it is conducive to fixing the link ring. The load-bearing part is the abutment part between the link ring and the oil storage cylinder, so that the lateral force generated by the compression is borne entirely by the oil storage cylinder, and the intermediate cylinder will not bear the lateral force, thereby preventing the connection part between the link ring and the intermediate cylinder from loosening, thereby ensuring the stable and reliable operation of the electronically controlled shock absorber.

[0008] Preferably, a first through hole is formed in the oil storage cylinder, and the valve seat is fixed on the outer wall of the oil storage cylinder at the first through hole.

[0009] Preferably, a horizontal step is further provided on the outer wall of the oil storage cylinder between the valve seat and the first through hole, so that the end of the link ring away from the intermediate cylinder fits on the horizontal step.

[0010] Preferably, a second through hole is formed on the intermediate cylinder, and one end of the link ring away from the solenoid valve is sealed and clamped on the second through hole.

[0011] Preferably, an outward-turned edge is provided on the outer wall of the middle cylinder at the second through hole, and a step is provided at one end of the link ring away from the solenoid valve to abut against the edge, and the outer wall of the end of the link ring is attached to the inner wall of the edge.

[0012] Preferably, an annular connecting sleeve is sleeved on the second through hole, and an end of the connecting ring away from the solenoid valve is provided with a step opening abutting against the top surface of the annular connecting sleeve, and the outer wall of the end of the connecting ring is fitted against the inner wall of the annular connecting sleeve.

[0013] Preferably, the outer wall of the end of the link ring is also sleeved with an O-ring.

[0014] Preferably, the valve seat is welded and fixed to the outer wall of the oil storage cylinder.

[0015] Preferably, the link ring is in a bell-mouth shape.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] 1. The solenoid valve is abutted on the lap platform, and one end of the link ring is limited between the solenoid valve and the outer wall of the oil storage cylinder. The assembly is simple and it is conducive to fixing the link ring. The load-bearing part is the abutment part between the link ring and the oil storage cylinder, so that the lateral force generated by the compression is borne entirely by the oil storage cylinder, and the intermediate cylinder will not bear the lateral force, thereby preventing the connection part between the link ring and the intermediate cylinder from loosening, and also reducing the risk of oil leakage caused by the center offset between the link ring and the edge caused by the lateral force, thereby ensuring the stable and reliable operation of the electronically controlled shock absorber.

[0018] 2. The horizontal step processed by the oil storage cylinder has a simple processing technology. It only needs to cooperate with the solenoid valve to ensure the sealing and smooth oil channel. It is fixedly connected by overlapping the plane of the oil storage cylinder, which is convenient for observation and inspection to see if there is any missing installation problem, thus reducing the risk of missing installation.

[0019] 3. The shock absorber structure is not only applicable to single-valve shock absorbers, but also to double-valve shock absorbers, thereby improving the adjustment range and response time of the shock absorber damping force. BRIEF DESCRIPTION OF THE DRAWINGS
