Title:
VALVE CORE ASSEMBLY AND BUILT-IN ELECTRONICALLY CONTROLLED SHOCK ABSORBER COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/044872
Kind Code:
A1
Abstract:
The present invention provides a valve core assembly used for a built-in electronically controlled shock absorber. The valve core assembly comprises a through-flow assembly provided in a valve core sheath. The through-flow assembly comprises: a valve body which has one side abutting against a solenoid valve assembly in the axial direction of the valve core assembly and is detachably fixed relative to the valve core sheath, the valve body being provided with a flow channel in fluid communication with a sheath through hole; and a moving member, extending through at least part of the valve body in the axial direction in a fluid sealing manner so as to transversely pass through the flow channel, and provided with a moving member through hole extending in the radial direction. The moving member can reciprocate in the axial direction under the action of electromagnetic force generated by the solenoid valve assembly so as to change the size of a through-flow cross section of the flow channel of the valve body. The present invention further provides a built-in electronically controlled shock absorber provided with the valve core assembly. By means of the structure, a damping force adjusting range of the electronically controlled shock absorber can be large, the structure is compact, and the response sensitivity is improved.
