Description

Technical Field

[0001] This utility model relates to the field of automotive testing equipment technology, specifically to an intelligent handheld optical brake disc wear detector. Background Technology

[0002] With the increasing popularity of automobiles, vehicle safety has become a prominent issue. As a crucial component of a car, the braking system's performance directly impacts vehicle safety. With advancements in vehicle technology, disc brake systems have gradually replaced drum brake systems, becoming the standard configuration for automotive braking. Disc brake systems utilize the friction between the brake disc and brake pads to decelerate or brake the vehicle. In vehicles equipped with disc brake systems, after a period of use, manually touching the edge of the brake disc will reveal a small step; this step indicates wear on the brake disc. In traditional brake disc inspection, technicians often manually touch the edge of the brake disc and estimate the degree of wear based on experience. If the edge step is too large, the brake disc needs to be re-pressed or replaced. This traditional inspection method relies on the technician's personal experience, making it difficult to detect uneven wear on the brake disc. Moreover, it cannot obtain accurate and quantifiable measurement results, which does not meet the needs of digital maintenance management. Therefore, we have proposed an intelligent handheld optical brake disc wear detector. Utility Model Content

[0021] Working Principle: Assemble the intelligent handheld brake disc wear optical inspector correctly according to the diagram. Once the inspector enters the power-on measurement interface, place the device's support pad 10 through the tire-rim gap to ensure it rests flat on the brake disc, based on the selected brake disc position. Then rotate the device to the appropriate angle to ensure the laser beam emitted by laser 8 is projected onto the outer edge of the brake disc. Press and release the button; a "beep" sound will be heard, indicating the device has emitted a laser to complete one measurement. If the selected measurement mode is dark mode, the first laser emission from laser 8 is for positioning, and the second laser emission completes the measurement. The measurement result is directly displayed on the touchscreen display 7 at the corresponding brake disc position. This optical inspector is equipped with a camera 9. The laser 8 and other precision optical components enable precise measurement of targets, achieving an accuracy of up to 0.1mm. A touchscreen display 7 controls the operation of the optical inspection instrument, simultaneously displaying corresponding graphics and data results. A camera 9 captures images of the brake disc, which are then processed by a data processing module to calculate the wear level of the brake disc, which is then displayed visually on the touchscreen display 7. Bluetooth and wireless modules allow for use with a mobile app. Through a customized data communication protocol, the app can connect to the device via Bluetooth, expanding the inspection tool's functionality to include photo capture, cloud storage of measurement records, detailed inspection reports, and historical data comparison.
