Description

Technical Field

[0001] This utility model relates to the field of electric vehicle parts technology, and in particular to a brake handle with a self-locking function. Background Technology

[0002] With the continuous advancement of urbanization and the accelerating pace of life, the demand for short-distance urban transportation is showing a significant upward trend. Among various modes of transportation, electric bicycles, with their comprehensive advantages such as small size, low energy consumption, moderate speed, easy parking, and low operating costs, are gradually becoming an indispensable and important component of the modern urban transportation system. More and more citizens are choosing electric bicycles as an important means of daily commuting and short-distance travel, which can effectively alleviate urban traffic congestion and avoid the overcrowding of public transportation during peak hours, providing an efficient, flexible, and economical solution for short-distance travel.

[0003] In the overall structure of an electric bicycle, the handlebar control system is a crucial component affecting vehicle safety and handling experience. The brake lever, as one of the most frequently used control components, is responsible for core functions such as acceleration, deceleration, and braking. Riders control the vehicle by squeezing the brake lever with their hands; therefore, the stability, flexibility, and safety of the brake lever structure directly impact the overall performance of the vehicle.

[0004] However, judging from existing industry practices and product structures, most electric bicycles use brake levers that lack an effective self-locking mechanism. In actual use, brake levers typically rely on cable tension or spring force to achieve rebound and braking, but they do not have locking capability after braking. This structure itself can meet basic braking needs during daily riding, but in specific application scenarios such as parking on slopes, temporary parking, pushing the vehicle, and locking the vehicle while standing, the lack of a self-locking brake lever can lead to insufficient braking or loss of braking stability, resulting in the vehicle being unable to achieve stable braking under certain usage conditions.

[0005] In conclusion, with the continuous expansion of electric bicycle usage scenarios and the gradual increase in users' requirements for vehicle safety and convenience, how to introduce a reliable self-locking function into the brake lever structure so that the brake lever can be safely locked when needed, thereby improving the overall handling stability, parking safety and ease of use of the vehicle, has become an important technical issue that urgently needs to be addressed in this field. Summary of the Invention

[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a brake handle with a self-locking function.

[0007] This utility model is achieved through the following technical solution: A brake lever with a self-locking function includes a brake lever fastening part and a brake lever handle. The brake lever handle is rotatably connected to one side of the brake lever fastening part. The brake lever fastening part is used to fix the brake lever handle on the handlebar.

When the brake lever handle is rotated and locked, the positioning piece is rotated, and the positioning piece abuts against the positioning block through the action of the elastic return member.

[0010] According to the above technical solution, preferably, the elastic restoring element is a torsion spring, the surface of the brake lever handle is provided with a positioning shaft, the positioning piece is sleeved on the positioning shaft and rotatably connected to the brake lever handle through the positioning shaft.

[0011] According to the above technical solution, preferably, the surface of the brake lever fastening part is provided with a limiting protrusion, and the positioning piece abuts against the limiting protrusion under the action of the elastic recovery member.

[0012] According to the above technical solution, preferably, a positioning groove adapted to the positioning block is opened on one side of the positioning piece, and the positioning piece and the positioning block abut against each other at the positioning groove.

[0013] According to the above technical solution, preferably, the positioning piece has two or more positioning slots on one side.

[0014] The beneficial effects of this utility model are: This utility model provides a positioning component consisting of a positioning plate and a positioning block between the brake lever handle and the brake lever fastening part. When the brake lever handle needs to be rotated and locked, the positioning plate can cooperate with the positioning block structure, and the elastic return member provides the necessary elastic force, so that the positioning plate can naturally lock after contacting the positioning block, realizing reliable self-locking of the brake lever, effectively preventing the vehicle from slipping or moving spontaneously, and improving the safety and reliability of temporary parking.

[0015] In addition, the entire locking process does not require complicated actions from the user. Instead, the locking is completed naturally during the braking process, which improves the ease of operation. Users can easily brake and lock with one hand. The overall structure is simple, reliable, and inexpensive, and can be widely used in electric bicycles, bicycles and other light two-wheeled vehicles, with good industrial application prospects.

[0022] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and preferred embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0023] In the description of the utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.

[0024] Furthermore, it should be noted that, in the description of this invention, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection, an indirect connection through an intermediate medium, or a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0025] In response to the problems that existing electric bicycle brake levers generally lack a locking structure, cannot maintain the braking state after braking operation, and pose a risk of slippage when the vehicle is parked on a slope or temporarily parked, requiring users to continuously exert force to maintain braking, this application provides a brake lever with a self-locking function, which achieves reliable self-locking of the brake lever through an innovatively designed positioning component.

[0026] As shown in the figure, this utility model includes a brake lever fastening part 6 and a brake lever handle 1. In this example, the brake lever handle 1 is rotatably connected to one side of the brake lever fastening part 6. The brake lever fastening part 6 is used to fix the brake handle on the handlebar. The brake lever handle 1 is used to control braking through the brake cable. The brake lever handle 1 is rotatably connected to the brake lever fastening part 6, and a positioning component is provided between the brake lever fastening part 6 and the brake lever fastening part 6. The positioning component can make the brake lever handle 1 rotate and lock.

[0027] The positioning component includes a positioning piece 2 connected to the brake lever handle 1 and a positioning block 7 fixedly connected to the surface of the brake lever fastening part 6. The positioning piece 2 can cooperate with the positioning block 7 to achieve rotational locking of the brake lever handle 1. In this example, the positioning piece 2 is rotatably connected to the surface of the brake lever handle 1. The positioning component also includes an elastic return member connected between the positioning piece 2 and the brake lever handle 1. When the brake lever handle 1 is rotated and locked, the positioning piece 2 is rotated, and the elastic return member causes the positioning piece 2 to abut against the positioning block 7. The surface of the brake lever fastening part 6 is provided with a limiting protrusion 3, and the positioning piece 2 abuts against the limiting protrusion 3 under the action of the elastic return member. This application uses simple mechanical components such as positioning plate 2, positioning block 7, and elastic return element to construct a positioning assembly. When it is necessary to rotate and lock the brake lever handle 1, the positioning plate 2 can cooperate with the positioning block 7 structure, and the elastic return element provides the necessary elastic force, so that the positioning plate 2 can naturally lock after contacting the positioning block 7, realizing reliable self-locking of the brake lever, improving the convenience of operation, and allowing users to easily brake and lock with one hand.

[0028] Specifically, the elastic return element is preferably a torsion spring. A positioning shaft 8 is provided on the surface of the brake lever handle 1. The positioning piece 2 is sleeved on the positioning shaft 8 and rotatably connected to the brake lever handle 1 via the positioning shaft 8. Simultaneously, a positioning slot 5 adapted to the positioning block 7 is provided on one side of the positioning piece 2, and the positioning piece 2 and the positioning block 7 abut against each other at the positioning slot 5. In this example, the positioning piece 2 has two or more positioning slots 5 on one side, preferably three, which can form multiple locking positions with the positioning block 7, allowing the brake lever handle 1 to achieve different degrees of braking lock according to different slopes, vehicle loads, or usage scenarios. This multi-stage positioning structure improves the flexibility of the brake lever, allowing users to select light, medium, or deep braking according to actual conditions, improving the comfort and safety of actual use.

[0029] Furthermore, in this example, the brake lever fastening part 6 preferably includes, but is not limited to, a fastening ring 4. The fastening ring 4 has an opening on one side, and the opening of the fastening ring 4 is connected by a threaded fastening structure. The threaded fastening structure includes a threaded hole provided at the opening of the fastening ring 4 and a fastening bolt threadedly connected to the threaded hole at the opening of the fastening ring 4. The installation between the brake lever and the handlebar is achieved through the threaded fastening structure.

[0030] In summary, this application achieves a self-locking function for the brake lever by adding a positioning component between the brake lever fastening part and the brake lever handle. This not only solves the safety hazard of vehicle slippage caused by the inability to lock the brake in the prior art, but also improves ease of use, structural stability, and applicability. The overall structure is simple, reliable, and inexpensive, and can be widely used in electric bicycles, bicycles, and other light two-wheeled vehicles, demonstrating significant application and promotion value.

[0031] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
