[0002] Two-wheeled bicycles are generally parked with a diagonal brace, which involves installing a flip-up diagonal brace bracket on one side of the rear half of the frame. However, since the length of the diagonal brace is fixed, it is unstable when parked with a diagonal brace on a terrain with a large slope, and the vehicle is prone to falling and causing injuries.

[0003] Currently, there are parking mechanisms on the market that lock the tires by squeezing the brake lever. These mechanisms are typically activated by a lever, requiring internal teeth or ratchets to engage and prevent reverse movement. This can cause the vehicle to disengage on steeply sloped terrain, leading to unstable parking. Furthermore, these mechanisms are complex and expensive. To address this, we propose a push-type parking mechanism and brake lever. Utility Model Content

[0004] The embodiment of the present application provides a push-type parking mechanism and brake handle to at least solve the problem that the locking function of the parking mechanism in the prior art is generally activated by a lever, and the internal teeth or ratchets need to be engaged to prevent reverse movement, which may cause the parking to disengage on the aforementioned terrain with a large slope, thereby causing unstable parking, and the structure is relatively complex and the cost is high.

[0039] Example 1

[0040] An embodiment of the utility model provides a push-type parking mechanism. Figure 1 It is a schematic diagram of the three-dimensional structure of a brake handle with a push-type parking mechanism according to an exemplary embodiment. Figure 2 FIG is an exploded view of a brake handle structure with a push-type parking mechanism according to an exemplary embodiment. Figure 1-2 As shown, the brake handle is a hydraulic brake handle, and the parking mechanism includes a base 30 and a brake handle 10 rotatably assembled on the base 30 by a rotating pin 20, and the base 30 is provided with a parking part 40 for locking the brake handle 10 in the braking position; the base 30 is the upper pump body of the oil brake. Furthermore, when the brake handle is a cable brake handle, the base 30 corresponds to the brake handle seat. It can be understood that the parking mechanism proposed in this application is not limited to the specific type of disc brake, and can be adapted to hydraulic brake handles and cable brake handles, and the brake handle 10 can cooperate with the oil pressure or cable to automatically reset elastically without restriction.

[0041] Figure 3 It is a schematic structural diagram of a push-type parking mechanism according to an exemplary embodiment. Figure 4It is a structural exploded view of a push-type parking mechanism according to an exemplary embodiment. Figure 5 FIG is an exploded view of a push-type parking mechanism structure according to an exemplary embodiment. Figure 3-5 The parking member 40 includes a positioning portion 401 integrally formed at the lower end of the brake handle 10 near the rotating pin 20. In this embodiment, a positioning groove 4011 is further provided on a side of the positioning portion 401 near the parking platform body 403 to cooperate with the annular side wall surface of the parking platform body 403.

[0042] An assembly platform 402 is fixed to the outer wall of the brake handle at a position corresponding to the positioning portion 401 by a plurality of assembly bolts 4021. A parking hole 4022 is defined in the center thereof and extends through the interior of the base. A lever slot 4023 is defined on the side thereof and extends through the parking hole 4022.

[0043] A cylindrical pin 4033 has a first end fixedly mounted on the inner wall of the base, and a second end extending into a parking platform body 403 and elastically movably mounted thereon via an elastic member 404 sleeved on the cylindrical pin 4033. The parking platform body is movably mounted within the parking movable hole 4022. A plurality of parking buckle grooves 4034 are formed on the annular wall surface of the parking platform body 403. In this embodiment, the elastic member 404 is a compression spring.

[0044] The exit lever is rotatably assembled in the lever slot 4023 through the lever pin 4052, and a snap-fit portion 4051 is integrally formed at one end of the lever close to the parking platform body 403, and the snap-fit portion 4051 is snap-fitted into one of the parking snap slots 4034; further, a return torsion spring 4053 is also sleeved on the lever pin 4052, and the two ends of the return torsion spring 4053 are respectively connected to the assembly platform 402 and the exit lever 405.

[0045] In the technical solution of the above embodiment, Figure 6 FIG1 is a schematic diagram of a non-parking state of a push-type parking mechanism according to an exemplary embodiment. Figure 7 FIG is a schematic diagram of a parking state of a push-type parking mechanism according to an exemplary embodiment. Figure 1-7 Under normal circumstances, the parking platform body 403 does not contact the positioning portion 401 at the lower part of the brake handle 10 due to the elastic force of the elastic member 404, and the exit lever 405 cooperates with the parking buckle groove 4034 on the side close to the cylindrical pin 4033 to position the parking platform body 403;

[0046] When the rider squeezes the brake lever 30 to brake the front / rear wheel of the bicycle, the brake lever 10 rotates along the rotating pin 20 to reach the braking position, and then presses the parking platform body 403 to gradually advance to the positioning portion 401 and cooperate with the positioning groove 4011 to achieve positioning. At this time, the reset of the brake lever 10 requires the positioning portion 401 to rotate along the rotating pin 20. At this time, the reset movement of the positioning portion 401 interferes with the side wall of the parking platform body 403, and the buckle portion 4051 of the withdrawal lever 405 is engaged with another parking buckle groove 4034 for positioning, providing the parking force required for the brake lever 10 to prevent reverse movement. The operation is simple and convenient, the parking is stable, and the processing cost is low. It can effectively adapt to the parking force required by the brake lever 30 under low-cost conditions, and achieve a fast bicycle parking effect.

[0047] It is understandable that Figure 8 FIG. 1 is a schematic diagram of a parking release state of a push-type parking mechanism according to an exemplary embodiment. Figure 8 When the parking needs to be released, the exit lever 405 is pushed counterclockwise, and the exit lever 405 rotates along the lever pin 4052, and its locking portion 4051 leaves the locked parking buckle groove 4034. The brake handle 10 is lightly squeezed, and the parking platform 403 can be withdrawn under the elastic force of the elastic member 404. The brake handle 10 cooperates with the oil pressure or the pull cable to automatically reset elastically without restriction, and the bicycle can be ridden freely.

[0048] Optionally, continue to refer to the attached Figure 2-3 The end of the parking platform body 403 away from the cylindrical pin 4033 is integrally formed with a button portion 4032, which is convenient for operation and pressing; the end of the parking platform body 403 close to the cylindrical pin 4033 is integrally formed with a frustum portion 4031 whose diameter gradually increases from one side of the cylindrical pin 4033 to the other side, which facilitates the parking platform body 403 to be gradually pressed into the positioning groove 4011, thereby improving the convenience of parking.

[0049] In summary, the push-type parking mechanism provided by the embodiment of the present invention is that when the rider squeezes the brake lever 30 to brake the front / rear wheels of the bicycle, the brake lever 10 rotates along the rotating pin 20 to reach the braking position, and then presses the parking platform 403 to gradually advance it to the positioning part 401 and cooperate with the positioning groove 4011 to achieve positioning. At this time, the resetting of the brake lever 10 requires the positioning part 401 to rotate along the rotating pin 20. At this time, the resetting movement of the positioning part 401 interferes with the side wall of the parking platform 403 and cannot be reset. The buckle part 4051 of the exit lever 405 engages the parking buckle groove 4034 for positioning. The parking platform 403 provides the parking force required to prevent the brake lever 10 from reverse. The operation is simple and convenient, the parking is stable and the processing cost is low. It can effectively adapt to the parking force required by the brake lever 30 under low-cost conditions, and achieve a fast bicycle parking effect.

[0053] For other structures not described, refer to Example 1.

[0054] In summary, the push-type parking mechanism and brake handle provided by the embodiment of the present invention, when the rider squeezes the brake handle 30 to brake the front / rear wheel of the bicycle, the brake handle 10 rotates along the rotating pin 20 to reach the braking position, and then presses the parking platform 403 to gradually advance it to the positioning part 401 and cooperate with the positioning groove 4011 to achieve positioning. At this time, the resetting of the brake handle 10 requires the positioning part 401 to rotate along the rotating pin 20. At this time, the resetting movement of the positioning part 401 interferes with the side wall of the parking platform 403 and cannot be reset. The buckle part 4051 of the exit lever 405 engages the parking buckle groove 4034 for positioning. The parking platform 403 provides the parking force required for the brake handle 10 to prevent reverse movement. The operation is simple and convenient, the parking is stable and the processing cost is low.
