[0014] The utility model will be further detailed in the following with the embodiment given by the accompanying drawings.

[0015] Referring to Figs. 1-3 As shown in the figure, a handlebar parking structure, including brake handle 1, handlebar seat 2, pivot 3, brake handle 1 with handlebar seat 2 through with pivot 3 hole shaft cooperation realizes rotation, handlebar seat 2 is equipped with the torsional spring for driving brake handle 1 reset in, the both ends of pivot 3 are equipped with the first baffle 4 and second baffle 5 of limit pivot 3 and get out handlebar seat 2, handlebar seat 2 corresponding first baffle 4's position is equipped with with its anti-rotation cooperation first limit slot 6, pivot 3 is equipped with limit block 7, brake handle 1 with handlebar seat 2 corresponding limit block 7 below is equipped with the second limit slot 8 of intercommunication, second limit slot 8 is used for limit block 7 along the axial direction of pivot 3 and moves downward, second limit slot 8 extends third limit slot 9 along the radial direction of pivot 3, third limit slot 9 is used for brake handle 1 relative limit block 7 and rotates, third limit slot 9 extends fourth limit slot 10 along the axial direction of pivot 3, fourth limit slot 10 is used for limit block 7 along the axial direction of pivot 3 and moves upward, when limit block 7 is located in fourth limit slot 10, first baffle 4 cooperates with first limit slot 6 to limit brake handle 1 reset, second baffle 5 and handlebar seat 2 between being equipped with spring 11 that exerts pressure upward.

[0016] The first stopper 4 is integrally formed with the rotating shaft 3, and the second stopper 5 is fixedly connected to the other end of the rotating shaft 3, cooperates with the first stopper 4 to limit the rotating shaft 3 from both sides in the axial direction, and prevents the rotating shaft 3 from being pulled out of the handle seat 2 during operation. The limiting block 7 is installed on the rotating shaft 3 by welding or key groove clamping and moves synchronously with the rotating shaft 3. The second limiting groove 8 on the brake handle 1 is in an up-down alignment state with the second limiting groove 8 on the handle seat 2 and is in communication with each other, forming a channel for the downward movement of the limiting block 7. The third limiting groove 9 extends in a direction matching the rotating track of the brake handle 1, so that the brake handle 1 can rotate relative to the limiting block 7 and align the fourth limiting groove 10 with the limiting block 7. The fourth limiting groove 10 extends upward from the end of the third limiting groove 9 away from the second limiting groove 8, forming a channel for the upward movement of the limiting block 7. The limiting block 7 can only move up and down in the fourth limiting groove 10. The spring 11 is sleeved on the rotating shaft 3, one end of which abuts against the lower surface of the second stopper 5, and the other end abuts against the handle seat 2, providing the rotating shaft 3 with continuous upward elastic pressure. When the parking function is needed, the second stopper 5 is pressed to make the limiting block 7 move downward along the second limiting groove 8. When the limiting block 7 moves to the bottom of the second limiting groove 8, the brake handle 1 is pulled to align the fourth limiting groove 10 with the limiting block 7, and then the pressing of the second stopper 5 is released to make the limiting block 7 enter the fourth limiting groove 10. Due to the anti-rotation cooperation between the first stopper 4 and the first limiting groove 6, the brake handle 1 cannot rotate relative to the limiting block 7, thereby achieving the locking of the brake handle 1. When the parking function needs to be released, the second stopper 5 is only pressed to make the limiting block 7 move downward, so that the limiting block 7 is separated from the fourth limiting groove 10. The brake handle 1 rotates relative to the limiting block 7 under the action of the torsional spring, so that the limiting block 7 is aligned with the second limiting groove 8. At this time, the pressing of the second stopper 5 is released to reset the limiting block 7.

[0017] In order to facilitate the assembly and subsequent maintenance of the rotating shaft 3 and the second stopper 5, in an optional scheme, the second stopper 5 is screwed with the rotating shaft 3. The end of the rotating shaft 3 is provided with external threads, and the central position of the second stopper 5 is provided with an internal threaded hole. The second stopper 5 is screwed on the rotating shaft 3 by threads. When the internal components need to be maintained or replaced, the second stopper 5 can be disassembled by reversing the rotation, without damaging other components, reducing the difficulty of maintenance. By adjusting the screwing degree of the second stopper 5, the initial compression amount of the spring 11 can be appropriately adjusted, and the upward pressure of the spring 11 on the rotating shaft 3 is adjusted to adapt to the operation feel requirements in different use scenarios, improving the universality of the structure.

[0018] Further, the second retaining edge 5 can be further optimized to improve the convenience of operation. A plurality of protrusions 12 for increasing friction are arranged on the outer surface of the second retaining edge 5. The protrusions 12 are strip-shaped structures uniformly distributed along the outer circumference of the second retaining edge 5. When assembling or disassembling the second retaining edge 5, the hands of the operator are in contact with the protrusions 12. The protrusions 12 can effectively increase the friction between the hands and the outer surface of the second retaining edge 5, avoid slipping during rotation, and make the tightening or loosening operation of the second retaining edge 5 more labor-saving and convenient.

[0019] In some options, in order to improve the stability of the spring 11 installation and avoid its deviation during work, the handle seat 2 is provided with a positioning groove for the spring 11. The positioning groove is a circular groove opened on the handle seat 2, and the diameter thereof matches the outer diameter of the spring 11. The inner wall of the positioning groove limits the spring 11 in the radial direction, preventing the spring 11 from deviating laterally during compression or reset.

[0020] In order to ensure the stable anti-rotation cooperation between the first retaining edge 4 and the first limiting groove 6, in another optional scheme, the first retaining edge 4 has a polygonal or rectangular profile. After the first retaining edge 4 is embedded in the first limiting groove 6, due to the characteristics of the polygonal or rectangular structure, the side surface thereof is tightly fitted with the inner wall of the limiting groove, and cannot rotate relatively, thereby realizing reliable anti-rotation cooperation.

[0021] The above is only a preferred embodiment of the present application, and the protection scope of the present application is not limited to the above-mentioned embodiments. Any technical solution falling within the concept of the present application belongs to the protection scope of the present application. It should be noted that, for ordinary skilled persons in the technical field, some improvements and decorations without departing from the principles of the present application are also considered as the protection scope of the present application.
