Abstract
Description
Technical Field
[0001] The utility model relates to the field of electric bicycles, in particular to an anti-skid auxiliary device for electric bicycles. Background Technique
[0002] An electric bicycle refers to a special bicycle that uses a battery as an auxiliary energy source and is equipped with a motor, a controller, a battery, a handlebar, a brake handle and other control components on the basis of an ordinary bicycle to realize functions of manual pedal riding, electric or electric-assisted driving; when in use, the battery electric energy is converted into mechanical energy by the motor to drive the wheels to rotate; due to its convenience and labor-saving, electric bicycles have been increasingly used as personal transportation tools.
[0003] When an electric bicycle is running electrically, a signal from the handlebar is transmitted to the motor through the controller to make the electric bicycle motor rotate. The existing braking structure is composed of a brake disc installed on the rear wheel and a brake wire connected to the brake handle. When braking, after the controller receives the signal, it will cut off the power supply to the motor, and control the brake disc through the brake wire connected to the brake handle to perform braking. Although this braking method is effective and fast, when the tire suddenly stops rotating at high speed, the electric bicycle will slide due to inertia and cause the tire to rub against the ground, and it is very easy to occur the situation of side-slip and rollover during this process, thus causing personal injury to the driver.
[0004] Therefore, we propose an anti-skid auxiliary device for electric bicycles to solve the above problems. Content of the Utility Model

Thus, features defined with "first", "second", etc. may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality" is two or more.
[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "mounted", "connected", "coupled" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific circumstances.
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts shall fall within the protection scope of the present utility model.
[0023] Please refer to Figures 1-4, in the present utility model, an anti-skid auxiliary device for an electric bicycle includes a brake caliper housing 1. A brake disc 2 is provided below the brake caliper housing 1. A rotating rod 4 is fixedly connected to the outer surface of the brake disc 2. Two recesses 5 are formed inside the brake caliper housing 1. An electric hydraulic rod 6 is fixedly connected to the inside of each recess 5. The output ends of the two electric hydraulic rods 6 are both fixedly connected with brake plates 7. A connecting block 8 is fixedly connected to the bottom surface of the brake caliper housing 1. A processing device 9 is fixedly connected to the bottom surface of the connecting block 8. An inductor 10 is fixedly connected to the bottom surface of the processing device 9. Through the cooperation of the provided processing device 9 and the inductor 10, when braking, the inductor 10 senses whether the rotating rod 4 rotates and conveys a signal to the processing device 9. The processing device 9 will convey a signal to the electric hydraulic rod 6 and quickly extend and retract it for spot braking. When conveying the signal during braking, the brake handle is electrically connected to the processing device 9 through a wire. When braking, after holding the brake handle, a braking signal will be conveyed to the processing device 9 to conduct signal transmission in this way.
[0024] An instruction board 12 is provided on the front surface of the brake disc 2. The back surface of the instruction board 12 is fixedly connected to the front surface of the brake caliper housing 1. The thickness of the instruction board 12 is 0.5 cm. Four mounting holes 13 are formed on the outer surface of the brake caliper housing 1. Through the provided instruction board 12, the model of the device can be provided for maintenance personnel to facilitate maintenance. Through the provided mounting holes 13, it is convenient for workers to assemble the device with components such as the wheel hub.
[0025] The processing device 9 is electrically connected to the inductor 10 and the electric hydraulic rod 6 through wires. Ventilation grooves 3 are formed on the outer surface of the brake disc 2. A sealing ring 11 is fixedly installed inside the recess 5. The inner ring of the sealing ring 11 fits the outer surface of the electric hydraulic rod 6. The sealing ring 11 is made of silicone material. The brake plate 7 is composed of a brake pad, a steel back plate, an underlying clamp, and a brake shoe. Through the provided ventilation grooves 3, when the brake disc 2 generates high temperature, the heat can be dissipated from the inside of the ventilation grooves 3 by rotation, which can increase its heat resistance. Through the provided sealing ring 11, it can effectively prevent dust and other items from entering the inside of the recess 5, thus damaging the electric hydraulic rod 6.
[0026] The working principle of the present utility model is:
[0027] When braking, the processing device 9 receives a signal and starts to extend the electric hydraulic rod 6, driving the brake plate 7 to move so that the brake plate 7 contacts the brake disc 2. After contact, the inductor 10 will sense that the rotating rod 4 is not rotating and convey a signal to the processing device 9. The processing device 9 will contract the electric hydraulic rod 6, so that the brake plate 7 moves away from the brake disc 2. Since the braking signal is not released, the electric hydraulic rod 6 will drive the brake plate 7 to continue to contact the brake disc 2, repeating this process to perform spot braking, thus avoiding the situation of skidding or drifting caused by sudden braking of the electric bicycle.
