New description: [New technical field] [0001] This creation is related to a damping adjustment device, especially a damping device for shock absorbers. [Prior Art] [0002] Shock absorbers are widely used in vehicles to cushion the unpleasant road surface or the vibration or sinking of the vehicle when braking, which increases the stability of the ride and the comfort of the ride. In order to respond to different road conditions and different vehicle loads, the shock absorbers are often provided with a damping adjustment structure, and the response sensitivity of the shock absorber can be adjusted according to personal preference or vehicle type. [0003] A general shock absorber mainly comprises a piston and a damping oil filled with high viscosity, and the piston pressurizes the damping oil to pass through a small-aperture valve to generate a compression or tensile shock absorber. The resistance (damping) of the device can change the size of the damping if the aperture of the valve is changed. [0004] Shock absorbers are closely related to driving safety, and many patents have been continuously improved. For example, the Republic of China Patent No. M2961 66 "Improvement Structure of Shock Absorber Side Flow Adjustment", the former case discloses a avoidance The pressure-side flow adjustment of the shock absorber is improved by a pressure-measuring flow regulator to provide a predetermined pressure relative to a hydraulic oil flow circuit, so that the shock absorber can be configured to utilize a damping regulator and a pressure-measuring flow regulator. The upper and lower compression and recovery reactions of the shock absorber can be adjusted separately to effectively improve the shock absorption effect and make the ride more comfortable. For example, the "damper dampering device of the shock absorber" of the Republic of China Patent No. M367829, the prior case discloses a damping adjustment device comprising a body, a transmission rod, a top pressing block, a valve seat and a shrapnel a valve, the top pressing block is screwed to the transmission rod, and is driven by the rotation of the main body by the rotation of the driving form No. A0101, the valve seat is fixed in the tail of the body, and the spring valve is The end is respectively abutted against the top pressing block and the spring piece valve, and the structure is simple, and the user can operate the damping adjusting device with an empty hand without using a tool to adjust the damping strength of the shock absorber. For example, the oil passage adjusting device of the shock absorber device of the Republic of China Patent No. M342953, which discloses an oil passage adjusting device for a shock absorber, is disposed between a shock absorber and a buffer device, and includes An inner liner is disposed inside the outer liner, the inner liner is axially disposed with an adjusting rod and a positioning member, and an ejector disc and a disc group are disposed on the outer side of the positioning member.

In the case of limited space, there are disadvantages of inconvenient assembly adjustment. [New content] [0006] The main purpose of this creation is to solve the adjustment of the adjustment part of the above-mentioned adjustment device, the control part will axially displace with the flow, and the gradual extension will be longer or shorter, on a limited assembly frame. For the above purpose, the present invention provides a damping adjustable device for a shock absorber, which is disposed between the first oil tank and the second oil groove, and the damping form of the shock absorber No. A0101 Page 5 of 24 M417274 The adjustable device includes a valve seat body, a high flow valve mechanism and a low flow valve n mechanism.

[0015] Referring to FIG. 3-1, when a damping oil in the first oil groove 20 flows back through the return passage 114 to the second oil groove 3〇, the valve piece 116 is subjected to the valve piece 116. The returning force of the damping oil compresses the elastic member 117, and the ejector valve piece 116 causes the elastic valve to open 115. The damping oil flows back through the third opening 119 to the second oil groove 30. Please refer to "3-2" When the damping oil in the second oil groove 30 is pressurized from the second oil groove 3 into the accommodating space 118, the damping is caused by the direction in which the elastic member 117 abuts the valve piece 116 opposite to the return direction. The oil is blocked by the elastic valve body 115, Form No. A0101, page 9 / page 24, M417274 cannot flow into the return passage 114, so the damping oil will only pass from the high flow passage 113 and the low flow passage 12 6 . When the damping oil is under small pressure and the impulse is insufficient, the block 120 abutting against the high flow channel 11 cannot be pushed away, and flows from the low flow channel 126 to the first oil groove 20; when the damping When the oil is pressurized and has sufficient momentum, the damping oil pushes up the block 120, and the damping oil flows from the high flow channel 113 to the low flow channel to the first oil tank 20. [0016] The degree of opening and closing of the high-flow valve mechanism 12 determines the magnitude of the high-flow damping. The degree of opening and closing of the low-flow valve mechanism 13 determines the magnitude of the low-flow damping, and the following is the high-flow, low-flow damping. Explain in different situations. Referring to FIG. 4-1, the adjusting portion 123 is biased to cause the adjusting portion 123 to be rotated by the screwing portion 122 to be displaced to the position farthest from the elastic portion 124, thereby releasing the elastic portion 124. The restoring force of the elastic portion 124 presses against the block 120, so that the high flow channel 113 is abutted by the block 120 with a minimum force, so that the high flow damping reaches a minimum value; and the control portion 134 is biased to The control unit 134 interlocks the driving unit 135 to perform a rotation stroke to drive the sliding portion 133 to perform a rotation stroke, and drives the valve body 130 to be displaced in the second chamber 125 to cause the restricting portion 129 and the restricting portion 137. The cross-sectional area formed reaches a minimum value, and the low-flow damping reaches a maximum value. This embodiment is the embodiment in which the high-flow damping is the weakest and the low-flow damping is the strongest. [0017] Referring to FIG. 4-2, the adjusting portion 123 is biased to cause the adjusting portion 123 to be rotated by the screwing portion 122 to be displaced to the position closest to the elastic portion 124, thereby compressing the elastic portion 124. The resisting block 120 is pressed by the restoring force of the elastic portion 124, so that the high-flow flow passage 11 is abutted by the maximum force passage by the block form number A0101, page 10/24 pages 120, so that the high flow damping A maximum value is reached; the control unit 134 is biased to cause the control unit 134 to rotate the drive unit 135 to drive the slide unit 133 to rotate, and the valve body 130 is driven into the second chamber 125. Displacement, such that the cross-sectional area formed by the current limiting section 129 and the restricting portion 137 reaches a minimum value, so that the low-flow damping reaches a maximum value, and the embodiment is that the high- and low-flow damping are the strongest implementation examples. . [0018] Referring to FIG. 4-3, the adjusting portion 123 is biased to cause the adjusting portion 123 to be rotated by the screwing portion 122 to be displaced to the position closest to the elastic portion 124, thereby compressing the elastic portion 124. The high-flow flow passage 113 is abutted against the block 120 with a maximum force by the restoring force of the elastic portion 124, so that the high-flow damping reaches a maximum value; and the control portion 134 is applied to the control portion 134. The control unit 134 interlocks the driving unit 135 to perform a rotation stroke to drive the sliding portion 133 to perform a rotation stroke, and drives the valve body 130 to be displaced in the second chamber 125 to make the current limiting portion 129 and the limit. The cross-sectional area formed by the flow portion 137 reaches a maximum value, and the low-flow damping reaches a minimum value. This embodiment is an embodiment in which the high-flow damping is the strongest and the low-flow damping is the weakest. [0019] Referring to FIG. 4-4, the adjusting portion 123 is biased to cause the adjusting portion 123 to be rotated by the screwing portion 122 to be displaced to the position farthest from the elastic portion 124, thereby releasing the elastic portion 124. The high-flow flow passage 113 is abutted against the block 120 with a minimum force by the restoring force of the elastic portion 124, so that the high-flow damping reaches a minimum value; and the control portion 134 is applied to the control portion 134. The control unit 134 interlocks the driving unit 135 to perform a rotation stroke to drive the sliding portion 133 to perform a rotation stroke, and drives the form number A0101, page 11 of 24, M417274, the valve body 130 in the second chamber 125. Displacement, such that the cross-sectional area formed by the current limiting section 129 and the restricting portion 137 reaches a maximum value, so that the low-flow damping reaches a minimum value, and the implementation aspect is that the high- and low-flow damping are the weakest implementations. Example. [0020] The sliding portion 133 of the damping adjustable device 10 of the present invention is only abutting against the driving portion 135, and has no structure of fastening or locking each other, so the displacement is performed at the sliding portion 133. When the adjusting portion 135 is not displaced together, that is, during the adjustment, the second adjusting member 131 does not axially displace with the valve body 130, and the tapping protrusion is lengthened or shortened so as to be in a limited space.
