Abstract

The damping structure disclosed by the embodiment of the present application comprises a rotating part, a damping cylinder seat and a damping part. The damping cylinder seat has an oil groove which is not communicated along the circumference of the damping cylinder seat. The rotating part is sleeved with the damping cylinder seat and seals the oil groove. The damping part comprises a damping valve core and a damping baffle with a through hole. The damping valve core is penetrated by the outer wall of the rotating part into the inside of the oil groove, so as to divide the oil groove into a first oil cavity and a second oil cavity. The damping valve core is provided with a first opening and a second opening. The damping baffle is arranged in the inside of the damping valve core and is movable. Different damping forces are generated when the damping baffle is located at different positions. According to the embodiment of the present application, the flow direction of the fluid in the oil groove is different, the flow rate is different, and the damping force is also different when the movable damping baffle is used. Therefore, the damping force is formed, the shock absorption effect is achieved when the damping structure is connected with the wheel, and the damping structure is used for shock absorption.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used herein in the specification of the application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application; the terms "comprising" and "having," and any variations thereof, in the specification, claims, and foregoing drawings of this application, are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the specification, claims, or foregoing drawings of this application are used to distinguish different objects, not to describe a particular order.

[0051] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0052] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

[0053] Reference Figures 1 to 12 This application proposes a damping structure, including a rotating component 1, a damping cylinder seat 2, and a damping component 3;

[0054] The damping cylinder seat 2 has an oil groove 21 arranged along its circumference. The two ends of the oil groove 21 are not connected. The rotating part 1 is sleeved on the damping cylinder seat 2 and seals the oil groove 21.

[0055] The damping element 3 includes a damping valve core 31 and a damping baffle 32 having a through hole 321;

[0056] The damping valve core 31 is inserted into the oil groove 21 through the outer wall of the rotating member 1 and is connected to the rotating member 1. The damping valve core 31 divides the oil groove 21 into a first oil chamber 211 and a second oil chamber 212. The damping valve core 31 is provided with a first opening 311 and a second opening 312. The damping baffle 32 is disposed inside the damping valve core 31 and has a first movable position and a second movable position.

[0057] When the damping baffle 32 is in the first active position, the damping baffle 32 blocks the second opening 312, and the first oil cavity 211 and the second oil cavity 212 are connected through the first opening 311 and the through hole 321; when the damping baffle 32 is in the second active position, the first oil cavity 211 and the second oil cavity 212 are connected through the first opening 311 and the second opening 312.

[0058] In this embodiment, one end of the rotating component 1 is provided with a first connecting hole 13, and the damping valve core 31 is located inside the first connecting hole 13 and is engaged with the first connecting hole 13. After injecting a viscous liquid (such as brake fluid) into the oil tank 21, it is sealed. Since the two ends of the oil tank 21 are not connected, when the damping valve core 31 moves in the oil tank 21, the viscous liquid therein flows clockwise or counterclockwise relative to the damping component 3. The viscosity of the viscous liquid is relatively large. When the movement distance is certain, the flow time of an equal volume of fluid is greatly affected by the cross-sectional area of ​​the fluid. When the cross-sectional area of ​​the fluid is large, the flow rate is faster, and the flow time of a unit volume of liquid from the first oil chamber 211 to the second oil chamber 212 is shorter. When the cross-sectional area of ​​the fluid is small, the flow rate is slower, and the flow time of a unit volume of liquid from the second oil chamber 212 to the first oil chamber 211 is longer. The cross-sectional area of ​​the fluid can be controlled by the size of the first opening 311, the second opening 312, and the through hole 321.

[0059] For example, with Figure 4 For example, when the rotating part 1 rotates clockwise, the position of the damping cylinder seat 2 is fixed, and the damping part 3 also rotates in the same direction as the rotating part 1. The volume of the second oil chamber 212 is compressed, and the viscous liquid in it is squeezed, generating damping force. The liquid needs to flow into the first oil chamber 211. During the flow, the damping baffle 32 is pushed from near the second opening 312 to near the first opening 311, so that it is in the second active position. At this time, since the size of the second opening 312 and the damping baffle 32 are both smaller than the size of the first opening 311, after the viscous liquid flows in from the second opening 312, it can flow into the first oil chamber 211 through the through hole 321 or through the gap between the first opening 311 and the damping baffle 32. The fluid cross-sectional area is large and the flow velocity is fast. The process is relatively quick; when the rotating part 1 rotates in the opposite direction to the above direction, the damping part 3 also rotates in the opposite direction with the rotating part 1. The volume of the first oil chamber 211 is compressed, and the viscous liquid in it is squeezed out, generating a greater damping force. The liquid needs to flow into the second oil chamber 212. During the flow, the damping baffle 32 is pushed from near the first opening 311 to near the second opening 312, so that it is in the first active position. At this time, since the size of the damping baffle 32 is larger than or the same as the size of the second opening 312, it can block the second opening 312. After the viscous liquid flows in from the first opening 311, it can only flow into the second oil chamber 212 through the through hole 321. The fluid cross-sectional area is small, the flow rate is slow, and the time is long, thus producing a damping effect.

[0060] In another embodiment, one end of the damping baffle 32 can be movably connected to one side of the second opening 312. When the viscous liquid flows from the first oil cavity 211 to the second oil cavity 212, the damping baffle 32 is pushed to the first movable position. At this time, the damping baffle 32 blocks the second opening 312, and the viscous liquid can only flow into the second oil cavity 212 through the through hole 321. When the rotating member 1 rotates in the opposite direction, when the viscous liquid flows from the second oil cavity 212 to the first oil cavity 211, the viscous liquid pushes the damping baffle 32, causing the damping baffle 32 to rotate about the movable end as the axis (that is, at this time the damping baffle 32 is a door of the second opening 312, and the movable connection can be or similar to a hinge connection). At this time, the damping baffle 32 is in the second movable position and no longer blocks the second opening 312, so the viscous liquid can flow from the second opening 312 to the first opening 311. In addition, a protrusion can be provided on the rotation path of the movable end of the damping baffle 32 to limit the rotation angle of the damping baffle 32, so that the damping baffle 32 cannot continue to rotate when it rotates relative to the second opening 312 to a certain angle, such as 45 degrees, 60 degrees or 75 degrees, so as to ensure that when the viscous liquid flows from the first oil cavity 211 to the second oil cavity 212, it can push the damping baffle 32 located in the second movable position, so that it rotates back to the first movable position with the fixed end as the axis.

[0061] In another embodiment, a rotating shaft can be provided inside the damping valve core 31, and a through hole 321 extending vertically through the damping baffle 32 can be provided inside the damping baffle 32, allowing the rotating shaft to pass through. The damping baffle 32 can rotate around the rotating shaft. When not affected by external force, the damping baffle 32 remains in a position parallel to the first opening 311 and the second opening 312, with both ends abutting against the inner sidewall of the damping valve core 31. A first protrusion is provided on the side of the damping baffle 32 near the second opening 312, so that when the viscous liquid flows from the first oil chamber 211 to the second oil chamber 212, the damping baffle 32 cannot rotate. At this time, the damping baffle 32 is in the first active position, and the viscous liquid can only flow through the through hole 321 on the damping baffle 32; while the viscous liquid flows from the second oil chamber 212 to the second oil chamber 212... When the first oil chamber 211 flows, it pushes the damping baffle 32 to rotate around the pivot, and is blocked by the second protrusion. The first and second protrusions limit the rotation angle of the damping baffle 32, so that it can only rotate within a certain range, such as 45 degrees, 60 degrees or 75 degrees. The smaller the rotation angle, the smaller the gap between the damping baffle 32 and the inner wall of the damping valve core 31, the longer the fluid flows, and the greater the damping force generated. The viscous liquid can flow through the gap between the damping baffle 32 and the inner wall of the damping valve core 31 after flowing through the second opening 312, and then flow to the first opening 311. When the viscous liquid flows in the opposite direction, it pushes the damping baffle 32 back to the first active position. Through the reciprocating motion of the damping baffle 32, the device connected to the damping structure can move smoothly.

[0062] In different embodiments, the diameter of the first opening 311 can be set to approximately 10-20 mm, and correspondingly, the diameter of the second opening 312 can be set to approximately 5-10 mm, and the diameter of the through hole 321 can be set to approximately 1-2 mm. There are no specific limitations on the exact values, as long as the above-mentioned scheme can be achieved. The viscous liquid placed inside the oil tank 21 is preferably a liquid with excellent resistance stability and buffering properties, such as brake fluid or damping grease. The number of through holes 321 can be changed according to actual needs, such as... Figures 1 to 9 As shown, only one through hole 321 can be set, or it can be done as follows. Figures 10 to 12 As shown, two through holes 321 are provided, as long as the time for fluid to flow through the through holes 321 can be controlled within an appropriate range.

[0063] In one embodiment, the damping structure further includes a fixed shaft 4, a damping cylinder seat 2 is sleeved on the fixed shaft 4, a first limiting structure is provided on the damping cylinder seat 2, and a second limiting structure is provided on the fixed shaft 4, with the first limiting structure and the second limiting structure engaging.

[0064] In this embodiment, the rotating component 1 rotates around the fixed shaft 4, and the damping cylinder seat 2 is located between the rotating component 1 and the fixed shaft 4. Due to the cooperation of the first limiting structure and the second limiting structure, the damping cylinder seat 2 is fixed on the fixed shaft 4. The position of the damping cylinder seat 2 is fixed, and the positions of both ends of the oil groove 21 are fixed. Only the damping component 3 moves within the oil groove 21.

[0065] In one embodiment, the first limiting structure is a protruding rib 41 provided on the outer wall of the fixed shaft 4, and the second limiting structure is a groove 22 provided on the inner wall of the damping cylinder seat 2 that is adapted to the protruding rib 41, and the protruding rib 41 and the groove 22 are engaged.

[0066] In this embodiment, the damping cylinder seat 2 is fixed on the fixed shaft 4 by the cooperation of the rib 41 and the groove 22. In different embodiments, such as Figures 1 to 5 ,as well as Figures 10 to 12 As shown, the fixed shaft 4 is a D-shaped shaft, and the through hole 321 inside the damping cylinder seat 2 is set as a D-shaped hole adapted to the D-shaped shaft. The damping cylinder seat 2 is fixed to the fixed shaft 4 by the mating of the D-shaped shaft and the D-shaped hole. Alternatively, the fixed shaft 4 can be set as a double flat shaft, and the through hole 321 inside the damping cylinder seat 2 can be set as a corresponding oval hole, achieving a similar effect.

[0067] In one embodiment, an upper bearing 42 and a lower bearing 43 are sleeved on the fixed shaft 4. The upper bearing 42 is located on one side of the damping cylinder seat 2, and the lower bearing 43 is located on the other side of the damping cylinder seat 2. The rotating component 1 is movably connected to the fixed shaft 4 through the upper bearing 42 and the lower bearing 43.

[0068] In this embodiment, the rotating component 1 rotates relative to the fixed shaft 4 via the upper bearing 42 and the lower bearing 43. The upper bearing 42 and the lower bearing 43 are used to support the rotating component 1 and reduce the friction between the rotating component 1 and the fixed shaft 4, so that the rotating component 1 rotates more smoothly.

[0069] In one embodiment, the rotating component 1 is a rotating cylinder 11, and the damping structure further includes a first rotating arm 12 and a limiting component;

[0070] The first rotating arm 12 is connected to the rotating drum 11, and the first rotating arm 12 is used to connect the wheel;

[0071] One end of the fixed shaft 4 passes through the rotating drum 11 to connect to the suspension frame 8, and the other end of the fixed shaft 4 is detachably connected to the limiting component, which is engaged with the rotating drum 11 for limiting.

[0072] In this embodiment, the first rotating arm 12 is connected to the rotating drum 11 and can drive the rotating drum 11 to rotate. The limiting assembly includes a limiting cover 14, a spring 142, and a first screw 143. One end of the limiting cover 14 is provided with a connecting shaft 144, which is inserted into the fixed shaft 4 and circumferentially fixed by a circumferential limiting structure provided inside the fixed shaft 4. The connecting shaft 144 is a hollow structure and is set perpendicular to the cover plate of the limiting cover 14. The first screw is provided inside the connecting shaft 144. 143. The first screw 143 passes through the bottom of the connecting shaft 144 and is fixed to the fixed shaft 4. A spring 142 is fitted on the first screw 143. One end of the spring 142 abuts against the bottom of the connecting shaft 144, and the other end abuts against the nut of the first screw 143. In this way, since the first screw 143 is fixed, the spring 142 has an inward elastic force on the connecting shaft 144. This elastic force causes the cover plate of the limiting cover 14 to be pressed inward, so that the limiting cover 14 can be stably engaged with the rotating drum 11.

[0073] Limit engagement refers to the rotating drum 11 being able to move within a certain range relative to the limiting component, or the rotating drum 11 being relatively fixed to the limiting component, for example... Figure 6 As shown, the rotating drum 11 is provided with a first notch 111 and a second notch 112. The limiting protrusion 141 can be engaged with the rotating drum 11 through the first notch 111 or the second notch 112. The size of the first notch 111 is adapted to the size of the limiting protrusion 141, and the size of the second notch 112 is larger than the size of the limiting protrusion 141.

[0074] During normal bicycle operation, the limiting protrusion 141 engages with the second notch 112. When riding smoothly, the limiting protrusion 141 is located at one end of the second notch 112. When encountering bumps during the ride, the rotating drum 11 will rotate relative to the limiting protrusion 141. Due to the restriction of the second notch 112 by the limiting protrusion 141, the rotating drum 11 can only rotate within a small range. At this time, the liquid in the oil tank 21 will flow from the second oil chamber 212 to the first oil chamber 211. The damping baffle 32 is located in the second movable position, and the liquid can flow through the first opening and the through hole 321. At this time, the torsion spring 7 connected to the rotating drum 11 assists the rotating drum 11 to return to its original position. The liquid in the oil tank 21 flows from the first oil chamber 211 to the second oil chamber 212. The damping baffle 32 is pushed to the first movable position by the liquid. The liquid can only flow through the through hole 321, and the flow rate is greatly reduced, generating a large damping force, thus achieving the damping effect.

[0075] In another embodiment, such as Figures 1 to 5 and Figures 10 to 12 As shown, a second rotating arm 6 can be connected to the first rotating arm 12. The second rotating arm 6 is connected to both ends of the fixed shaft 4 and can rotate relative to the first rotating arm 12 around the fixed shaft 4. The other end of the second rotating arm 6 can be connected to other devices.

[0076] In one embodiment, the damping cylinder seat 2 has a first sealing groove 23 on each side of the oil groove 21, and a first sealing ring 24 is provided in each of the two first sealing grooves 23.

[0077] In this embodiment, two first sealing grooves 23 sandwich the oil groove 21 in the middle, and the oil groove 21 is sealed by the first sealing ring 24, so that the rotating part 1 and the damping cylinder seat 2 are sealed, ensuring that there is no oil leakage during assembly. The sealing ring is preferably made of rubber, such as nitrile rubber or EPDM rubber, which are materials with stable performance.

[0078] In one embodiment, the damping element 3 further includes a sealing cap 33;

[0079] The outer side wall of the rotating part 1 is provided with a first connecting hole 13;

[0080] The damping valve core 31 has a second sealing groove 313 at its tail end, and a second sealing ring 314 is provided in the second sealing groove 313. The head of the damping valve core 31 passes into the first connecting hole 13, and the tail end of the damping valve core 31 is sealed to the first connecting hole 13 by the second sealing ring 314 and covered by the sealing cover 33.

[0081] In this embodiment, the first connecting hole 13 can be an external threaded hole, and its style can be as follows: Figure 6As shown, the damping valve core 31 is inserted into the first connecting hole 13 and is limited by the sealing cover 33 to prevent the damping valve core 31 from coming out of the first connecting hole 13 due to bumps during use. In addition, the second sealing ring 314 seals the damping valve core 31 with the first connecting hole 13 to ensure that there is no oil leakage during assembly. The second sealing ring 314 can be made of the same material as the first sealing ring 24.

[0082] In one embodiment, the damping valve core 31 is provided with an oil injection hole 315. One end of the oil injection hole 315 is connected to the oil groove 21, and the other end of the oil injection hole 315 is detachably connected to a second screw 316, which is used to seal the oil injection hole 315.

[0083] In this embodiment, viscous liquid is injected into the oil tank 21 through the oil injection hole 315. When the viscous liquid in the oil tank 21 needs to be replaced, the sealing cap 33 is unscrewed, the second screw 316 is removed, and auxiliary tools such as a syringe are used to draw the viscous liquid out of the oil tank 21. After injecting new oil, the second screw 316 is tightened again, and the viscous liquid is sealed in the oil tank 21 to achieve the purpose of reuse. When the user experience is affected by long-term use, the service life of the damping structure can be extended by replacing the second screw 316 or the viscous liquid.

[0084] In one embodiment, the rotating component 1 is provided with a second connecting hole 15, which is located on one side of the first connecting hole 13. The second connecting hole 15 is provided with a locking component 5, which includes a limiting rod 51. The limiting rod 51 can be inserted into the oil groove 21 and engaged with the damping valve core 31.

[0085] In this embodiment, as Figures 10 to 12 The diagram shows a preferred embodiment of the damping structure proposed in this application. When the limiting rod 51 is adjusted so that one end abuts against one side of the damping valve core 31, such as the second opening 312, it is equivalent to restricting the movement of the damping valve core 31. The damping structure then no longer has the effect of adjusting damping. When the limiting rod 51 is adjusted outward, the limiting rod 51 moves away from the damping valve core 31, and the damping structure can be used normally.

[0086] In one embodiment, the locking component 5 further includes a locking button 52 and a third screw 53;

[0087] The locking button 52 is connected to the limit rod 51 and is used to control the reciprocating motion of the limit rod 51;

[0088] The third screw 53 is detachably connected to the locking button 52, and the third screw 53 is used to fix the locking button 52.

[0089] In this embodiment, the locking button 52 is provided with a rotation mark. When it is necessary to adjust whether the damping valve core 31 is working, the third screw 53 is removed, the locking button 52 is rotated to a specific position according to the rotation mark, and then the third screw 53 is installed back to the original position to fix the locking button 52. The damping structure can then be used.

[0090] Obviously, the embodiments described above are only some embodiments of this application, not all embodiments.
