Title:
BICYCLE SADDLE HAVING MASSAGE FUNCTION BASED ON HYDRAULIC TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2021/042415
Kind Code:
A1
Abstract:
A bicycle saddle having a massage function based on hydraulic technology. The saddle is a bag-type structure and comprises a left bag cavity (1), a middle bag cavity (2) and a right bad cavity (3). The left bag cavity (1) and the right bag cavity (3) are symmetrically distributed relative to the middle bag cavity (2), and the left bag cavity (1), the middle bag cavity (2) and the right bag cavity (3) are filled with hydraulic oil. A damping hole (4, 6) is provided on a bag wall between the left/right bag cavity (1, 3) and the middle bag cavity (2), and a one-way valve (5, 7) is installed on the bag wall between the left/right bag cavity (1, 3) and the middle bag cavity (2); a liquid inlet of the one-way valve (5, 7) communicates with the left/right bag cavity (1, 3), and a liquid outlet of the one-way valve (5, 7) communicates with the middle bag cavity (2). A tension spring (8) is vertically installed within the middle bag cavity (2), and the tension spring (8) is fixedly connected between bag walls at the top and bottom of the middle bag cavity (2). When the left bag cavity (1) and the right bag cavity (3) are both in a non-compressed state, the tension spring (8) is in a retracted state, and the bag wall at the top of the middle bag cavity (2) is downwardly recessed under the force of the spring. When the left bag cavity (1) or the right bag cavity (3) is independently in a compressed state, the tension spring (8) is in a stretched state, and the bag wall at the top of the middle bag cavity (2) protrudes upward under the effect of hydraulic pressure.
