[0038] This utility model proposes a steering return mechanism 100.
[0039] Please see Figures 1 to 3 In one embodiment of this utility model, the steering return mechanism 100 is applied to a bicycle 200, the bicycle 200 includes a frame 210, and the steering return mechanism 100 includes a steering tube 10, a guide member 20 and a return assembly 30.
[0040] Specifically, the returning assembly 30 is arranged on the handlebar tube 10, and the handlebar tube 10 is rotatably arranged on the frame 210 of the bicycle 200, one end of the handlebar tube 10 is fixedly connected with the handlebar stem of the bicycle 200, and the other end is connected with the handle 220 of the bicycle 200 as a conducting component. In the embodiment, in order to make the handlebar tube 10 have the automatic returning function when being installed on the frame 210 of the bicycle 200, the guide 20 and the returning assembly 30 are further arranged, wherein the guide 20 is detachably arranged on the frame 210, for example, a threaded member is used to threadedly connect the guide 20 with the frame 210, and the guide 20 is fixed on the frame 210, and the returning assembly 30 is arranged on the outer periphery of the handlebar tube 10.
[0041] The returning assembly 30 comprises a positioning member 31, an abutting member 32, a first elastic member 33 and a guide member 34. The positioning member 31 is arranged on the outer periphery of the handlebar tube 10 and is arranged in a spaced manner with the guide 20 along the extension direction of the handlebar tube 10. The positioning member 31 is detachably arranged on the handlebar tube 10, or is integrally formed with the handlebar tube 10, and no more requirements are made thereon.
[0042] As to the abutting member 32, the abutting member 32 is movably arranged on the outer periphery of the handlebar tube 10 and is located between the positioning member 31 and the guide 20. The end of the guide 20 towards the abutting member 32 is provided with a guide slope 21, and the guide slope 21 has a first position and a second position along the extension direction of the handlebar tube 10, the first position is lower in height than the second position, and the surface connecting the first position and the second position is arranged in an inclined manner. The abutting member 32 is movably arranged on the guide slope 21, that is, the abutting member 32 can move along the guide slope 21, and when the abutting member 32 moves from the first position to the second position or from the second position to the first position of the guide slope 21, the height position of the abutting member 32 on the outer periphery of the handlebar tube 10 will change.
[0043] The guide member 34 is connected with the abutting member 32 and the handlebar tube 10 in a matched manner, and the guide member 34 can drive the abutting member 32 to rotate synchronously when the handlebar tube 10 turns, and the abutting member 32 moves up and down along the extension direction of the handlebar tube 10 under the guidance of the guide member 34 when the abutting member 32 moves. That is, since the first elastic member 33 is arranged between the abutting member 32 and the positioning member 31, when the handlebar tube 10 turns, the handlebar tube 10 drives the abutting member 32 to rotate synchronously through the guide member 34, and the abutting member 32 moves up and down along the extension direction of the handlebar tube 10 under the guidance of the guide member 34 when rotating due to the guide slope 21.
[0044] When the abutting member 32 moves along the extension direction of the steering pipe 10 towards the positioning member 31, the first elastic member 33 will be pressed, that is, when the abutting member 32 moves along the first position to the second position of the guide slope 21 of the guide member 20, the first elastic member 33 will be deformed after being pressed, so that the first elastic member 33 is in an energy gathering state. At this time, the first elastic member 33 has a driving force to drive the abutting member 32 to rotate along the second position to the first position of the guide slope 21 of the guide member 20.
[0045] When the steering external force applied to the steering pipe 10 disappears, the first elastic member 33 will drive the abutting member 32 to move from the second position to the first position of the guide slope 21 according to the driving force formed by the deformation, and the abutting member 32 will rotate when moving, at this time, the abutting member 32 drives the steering pipe 10 to rotate through the guide member 34, so as to achieve the effect of auxiliary return and automatic return.
[0046] In another embodiment, the steering pipe 10 is provided with a first long hole 11 along the extension direction thereof; the guide member 34 is protruded on the side of the abutting member 32 facing the steering pipe 10, and the guide member 34 is arranged in the first long hole 11 and is in sliding connection with the first long hole 11.

The hole length of the first long hole 11 is greater than or equal to the height from the first position to the second position of the guide slope 21. In this way, the first long hole 11 is designed to minimize the influence on the structural strength of the deflection pipe 10.

Since the guide 34 is used as a consumable part, the guide 34 needs to be replaced after a period of use. In order to facilitate the replacement of the guide 34 and ensure that the abutting piece 32 can be driven to rotate synchronously by the guide 34 when the deflection pipe 10 rotates. In the embodiment, the second long hole 321 is provided on the abutting piece 32, the second long hole 321 is provided in correspondence with the first long hole 11, and the guide 34 is inserted into the second long hole 321 and the first long hole 11 on one side by means of insertion. The second long hole 321 is also designed along the extension direction of the deflection pipe 10, and the hole length of the second long hole 321 can be designed in reference to the hole length of the first long hole 11 or can be smaller than the hole length of the first long hole 11. In the embodiment, the second long hole 321 is designed to facilitate the replacement and installation of the guide 34.
