DETAILED DESCRIPTION

[0036] In order to enable personnel in the technical field to better understand the technical solutions of the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0037] The present application will be further described in detail below in combination with the drawings of the specification.

[0038] The embodiments of the present application disclose a static brake detection system of an electric bicycle.

[0039] As shown in Figure 1 , Figure 3 and Figure 4 , a static brake detection system of an electric bicycle comprises a circuit board 1, a vibrating member 2, a vibration sensor 3 and a display screen 4; the circuit board 1 is arranged on a handlebar; the vibrating member 2 is arranged on a brake wall, and the vibrating member 2 is used for generating vibration; the vibration sensor 3 is arranged on the brake wall, and the vibration sensor 3 is electrically connected with the circuit board 1; the display screen 4 is arranged on the handlebar, and the display screen 4 is electrically connected with the circuit board 1, and the display screen 4 is used for displaying the wear of the brake.

[0040] The vibrating member 2 will generate vibration on the brake wall, and the vibration sensor 3 can collect vibration data of the brake wall.

[0041] When an operator presses the brake, the brake wall will move towards the hub and abut against the hub, and the abutment of the brake wall against the hub will affect the vibration of the vibrating member 2 on the brake wall, thereby affecting the vibration data collected by the vibration sensor 3.

[0042] When the brake wall fails, the brake wall will not be close to the hub, at this time, the vibration emitted by the vibrating member 2 is less weakened by the hub, and the value of the vibration data of the brake wall collected by the vibration sensor 3 is also less weakened.

[0043] When the brake wall works normally, the brake wall abuts against the hub, at this time, the vibration emitted by the vibrating member 2 is greatly weakened by the hub, and the value of the vibration data of the brake wall collected by the vibration sensor 3 is also greatly weakened.

[0044] According to the size of the vibration data collected by the vibration sensor 3, the wear of the brake can be reflected, and the display screen 4 is used for displaying, so that the user can know the brake wear condition of the vehicle in time, and the problem that the driver cannot know the brake wear condition of the vehicle before riding and the risk of traffic accidents caused by brake failure of the vehicle is solved.

[0045] Specifically, the vibration member 2 is a vibration motor, and the vibration member 2 itself can generate vibration. The vibration member 2 is arranged on the brake wall, so that the vibration generated by the vibration member 2 can be transmitted to the brake wall to make the brake wall vibrate.

[0046] Since the vibration sensor 3 is arranged on the brake wall, the vibration sensor 3 can collect vibration data from the brake wall and transmit the data to the circuit board 1.

[0047] Specifically, the vibration sensor 3 is a normally open vibration sensor 3, and in this embodiment, it is a SW-18010P normally open vibration sensor.

[0048] When the brake is started, the vibration motor generates a vibration frequency, and the vibration sensor 3 located outside the brake wall receives the vibration value. Since the brake wall has a small degree of wear, the engagement of the brake wall with the hub is better, so that the vibration efficiency of the vibration motor is weakened due to the complete engagement with the hub.

[0049] By programming (such as the vibration data processing program disclosed in CN117863782A), the vibration preset value is set in the program of the circuit board 1 in advance. The vibration preset value is the vibration data collected when the brake wall is not worn at all.

[0050] Then, during the actual brake detection operation, the vibration sensor 3 uploads the collected vibration data to the circuit board 1 and compares it with the vibration preset value. If the vibration data is greater than the vibration preset value, it is determined that the brake wall is worn.

[0051] Further, the wear state of the brake wall can be determined according to the difference between the vibration data and the vibration preset value. The greater the difference between the vibration data and the vibration preset value, the greater the degree of wear of the brake wall.

[0052] Finally, the difference between the vibration data and the vibration preset value will finally be displayed on the display screen 4 in the form of a percentage. The greater the percentage value, the more serious the wear state of the brake wall.

[0053] The electric bicycle static brake detection system comprises a vibration amplification spring 5, one end of the vibration amplification spring 5 is arranged on the vibration sensor 3, and the other end is in abutment with the brake wall.

[0054] Specifically, the vibration amplification spring 5 is in abutment with the brake wall, and the vibration generated by the brake wall is transmitted to the vibration sensor 3 through the vibration amplification spring 5. The arrangement of the vibration amplification spring 5 can amplify the vibration amplitude generated by the brake wall, thereby further improving the detection accuracy.

[0059] Specifically, the shape of the integrated box 6 is overall rectangular, and the integrated box 6 is a transparent integrated box, which is convenient for users to observe the structure in the containing space and adjust.

That is, the vibration sensor 3 is not directly connected with the integrated box 6, but is indirectly arranged on the integrated box 6 through the vibration amplification spring 5.

[0064] The vibration generated by the brake wall can be transmitted to the vibration amplification spring 5 through the integrated box 6, and transmitted to the vibration sensor 3 after the vibration is amplified by the vibration amplification spring 5.

[0065] The vibration piece 2 and the vibration sensor 3 are oppositely arranged, and there is a gap between them, which can prevent the vibration piece 2 from directly contacting the vibration sensor 3, so that the vibration generated by the vibration piece 2 is directly transmitted to the vibration sensor 3, affecting the accuracy of the brake test.

[0066] The integrated box 6 is arranged, and the vibration piece 2, the vibration sensor 3 and the vibration amplification spring 5 are integrated together.

[0074] The electric bicycle static brake detection system includes a control switch 13, and the control switch 13 is electrically connected with the circuit board 1.

[0075] Specifically, the control switch 13 is a press button, and the control switch 13 can be arranged on the circuit substrate 11 or on the handlebar, as long as the control switch 13 is electrically connected with the circuit substrate 11.
