Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of brake pad detection, and particularly relates to a brake pad thickness detection device. Background Technique
[0002] The brake pad is a key component in the vehicle braking system, usually composed of a steel plate, an adhesive heat insulation layer and a friction block. The brake pad is installed in the brake caliper and is in close contact with the brake disc (or brake drum). When the driver steps on the brake pedal, the brake pad will be subjected to a strong pressure, so as to generate friction with the brake disc (or brake drum), realizing the deceleration and parking of the vehicle. Due to the friction, the brake pad will be gradually worn. When it is worn to the limit position, it must be replaced, otherwise the braking effect will be reduced, and even safety accidents may occur. In the prior art, the detection method for the thickness of the brake pad generally uses a mechanical instrument tool with scale numbers for measurement. During the detection, manual reading, recording and comparative analysis are required to complete the detection and determination of the brake pad, resulting in low detection efficiency and easy occurrence of errors.

[0022] As Figures 1 to 5 shown, the brake pad thickness detection device of this embodiment includes a detection housing 1, a detection handle 2, and a detection positioning assembly 3.
[0023] A touch screen 5 is provided on the detection housing 1, and a thermal printer 6, an integrated circuit board 7, a speaker 8, and a storage battery 9 are installed inside the detection housing 1. The touch screen 5, the thermal printer 6, the speaker 8, and the storage battery 9 are electrically connected to the integrated circuit board 7.
[0024] One end of the detection handle 2 is provided with a wire 10 connected to the detection housing 1. The detection handle 2 includes a housing 21, a sliding assembly 22, a detection assembly 23 and an adjustment plate 24. The sliding assembly 22 is slidably arranged in the housing 21. The detection assembly 23 includes an induction strip 231, a sensor and a detection main board 232. The induction strip 231 is embedded at the bottom of the sliding assembly 22. The detection main board 232 is arranged below the induction strip 231. The sensor is installed on the detection main board 232 and is used to detect the displacement information of the induction strip 231. The adjustment plate 24 is slidably arranged outside the housing 21 and is fixedly connected to the sliding assembly 22.
[0025] The detection and positioning assembly 3 includes a positioning cylinder 31, a positioning block 32 and a probe 33. One end of the positioning cylinder 31 is fixedly connected to the housing 21. The positioning block 32 is fixedly connected to the other end of the positioning cylinder 31, and the positioning block 32 is perpendicular to the axis of the positioning cylinder 31 and protrudes from the outer wall of the positioning cylinder 31. One end of the probe 33 is coaxially slidably inserted through the positioning cylinder 31, and the other end is slidably inserted through the housing 21 and is fixedly connected to the sliding assembly 22.
[0026] It should be noted that the sensor can be an inductive displacement sensor or other types of sensors, as long as it can detect the displacement of the induction strip 231. When the sliding assembly 22 drives the induction strip 231 and the probe 33 to move, the inductive displacement sensor will detect the magnetic field change generated when the induction strip 231 moves and convert it into an electrical signal output, so as to obtain the required displacement information. This displacement information directly reflects the thickness of the brake pad. The displacement information is processed by the detection main board 232 to obtain the thickness data of the measured brake pad.
[0027] The working principle of this brake pad thickness detection device is as follows:
[0028] Since the brake disc is located inside the wheel and rotates coaxially with the wheel, while the brake pads are fixed inside the brake caliper and located on both sides of the brake disc. During braking, the two brake pads will clamp the brake disc in the middle. Therefore, during the test, the detection and positioning component 3 is directly inserted beside the wheel hub. The positioning block 32 on the positioning cylinder 31 is positioned on the plane of the brake pad. Then, by pushing the adjustment plate 24, the probe 33 is driven to penetrate out of the positioning cylinder 31 until the probe 33 contacts the plane of the brake disc. The length of the probe 33 penetrating out of the positioning cylinder 31 is the thickness value of the brake pad. At this time, the sensor detects the displacement information of the induction strip 231, and then cooperates with the detection main board 232 to process and obtain the thickness data of the measured brake pad, and transmits the thickness data to the integrated circuit board 7. The integrated circuit board 7 is embedded with an autonomous software, which can read and memorize the currently detected brake pad thickness data. The software automatically converts and analyzes the detected thickness data with the standard data to obtain a test report, without the need for manual memorization and copying of data. The integrated circuit board 7 processes the detected thickness data and performs data interconnection with the touch screen 5, the thermal printer 6, and the vehicle inspection system APP. The touch screen 5 can display the test results, the thermal printer 6 directly outputs a paper standard test report, the vehicle inspection system APP can directly take pictures and record the brake pad thickness condition, and process the test data to form a data portrait report, which is pushed to the vehicle owner online.
[0029] In this embodiment, the housing 21 includes a top cover 211 and a bottom shell 212 that are fixedly connected. A connection port 2111 is provided at the top of the top cover 211 along the length direction, and a first sliding groove 2112 communicating with the connection port 2111 is provided at the bottom of the top cover 211 along the length direction. A second sliding groove 2121 is provided at the top of the bottom shell 212 along the length direction. The sliding component 22 includes a sliding plate 221 and a connection block 222. The sliding plate 221 is slidably disposed on the second sliding groove 2121 and is fixedly connected to the probe 33. The connection block 222 is slidably disposed on the first sliding groove 2112 and is fixedly connected to the top of the sliding plate 221. The adjustment plate 24 is provided with a sliding portion 241 that is slidably connected to the connection port 2111, and a fixing screw 242 that is threadedly connected to the connection block 222.
[0030] In this embodiment, a fixing pin 4 is provided at one end of the first sliding groove 2112 away from the connection block 222. A connection groove is provided on the connection block 222. The sliding component 22 further includes a return spring 223. One end of the return spring 223 is sleeved on the fixing pin 4 and abuts against the end face of the first sliding groove 2112, and the other end abuts against the end face of the connection groove. After the thickness of the brake pad is detected, when the adjustment plate 24 is released, the return spring 223 can drive the sliding plate 221 and the probe 33 to reset.
[0031] Optionally, a protruding push block 243 is provided on the top of the adjustment plate 24, which facilitates the tester to push the adjustment plate 24.
[0032] It should be understood that all of the above embodiments are exemplary rather than restrictive. Under the concept of the present utility model, any modifications, equivalent changes and modifications made to the specific embodiments described above by those skilled in the art still fall within the scope of the technical solutions of the present utility model.
