Description

A brake pad wear detection device Technical Field

[0001] This utility model relates to the field of brake pad wear detection technology, specifically a brake pad wear detection device. Background Technology

[0002] Brake pads are one of the most important safety components in a car's braking system. Their function is to decelerate and brake the vehicle through friction. The friction between the friction pads and the brake disc or brake drum converts the vehicle's kinetic energy into heat energy, thereby achieving deceleration or stopping.

[0003] In the process of brake pad wear detection, the common method is to use a width measuring tool to measure the thickness and compare the measured value with the safe thickness value to achieve the detection purpose. This kind of detection requires measuring the accurate value of each one. However, for brake pads, as long as the thickness is greater than the safe thickness, normal use is guaranteed. Therefore, it is not necessary to measure the accurate thickness value to detect whether brake pads can be used safely. In order to avoid the reduced work efficiency caused by measuring the value of each one, it is necessary to design a brake pad wear detection device that can quickly detect wear.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3. This utility model provides a technical solution: it includes a fixed width plate 1 and an adjusting plate 2, which are hinged to each other. The fixed width plate 1 has a fixed width hole 11, and the adjusting plate 2 has an adjusting hole 21. A fixed plate 22 is fixed to the side wall of the adjusting hole 21. A movable plate 23 is installed on the side of the adjusting plate 2 away from the fixed plate 22. An adjusting component for driving the movable plate 23 to extend and retract is provided on the side wall of the adjusting hole 21. A fixed component 6 is provided between the fixed width plate 1 and the adjusting plate 2. A scale bar 4 is provided on the adjusting plate 2 at a position corresponding to the adjusting hole 21. There are three fixed width holes 11, and the widths of the three fixed width holes 11 decrease sequentially. Rotating the knob 52 drives the threaded rod 51 to rotate, thereby achieving the purpose of extending and retracting the movable plate 23, and thus adjusting the distance between the movable plate 23 and the fixed plate 22.

[0018] The adjustment assembly includes a telescopic groove 5, which is opened on the side wall of the fixed width hole 11 and is aligned with the movable plate 23. A threaded rod 51 is rotatably connected inside the telescopic groove 5. One end of the threaded rod 51 is threadedly connected to the adjustment plate 2, and the other end of the threaded rod 51 extends out of the fixed width plate 1 and is fixedly connected to a knob 52. A pair of guide rods 53 are fixed inside the telescopic groove 5, and the ends of the guide rods 53 are slidably connected to the adjustment plate 2.

[0019] The fixing component 6 includes a fixing hole 61 and a fixing rod 62. The fixing hole 61 is opened on the side of the adjusting plate 2 near the width fixing plate 1. The fixing rod 62 is installed on the width fixing plate 1 and its position is aligned with the fixing hole 61. The fixing rod 62 passes through the width fixing plate 1 and is slidably connected to the width fixing plate 1. A pull plate 63 is fixed to one end of the fixing rod 62 extending out of the width fixing plate 1. An installation groove 64 is opened in the width fixing plate 1 at a position corresponding to the fixing rod 62. A movable block 65 is slidably connected in the installation groove 64. A push-out spring 66 is fixed between the movable block 65 and the side wall of the installation groove 64. The movable block 65 is fixedly connected to the middle position of the fixing rod 62. A magnetic fixing strip 3 is fixed to the bottom of the width fixing plate 1 and the side away from the hinge.

[0020] Working principle: First, unfold and fix the width-fixing plate 1 and the adjusting plate 2. When testing brake pad wear, try to pass the brake pad through the designated width-fixing hole 11. If the brake pad can pass through normally, it indicates that its thickness is below the safe value; otherwise, it can be used normally. The whole process is relatively simple to operate and is more suitable for batch testing, which can greatly improve work efficiency. Furthermore, when testing different models of brake pads or brake pads with different safety levels, try to pass them through the width-fixing holes 11 of different widths. At the same time, the adjusting hole 21 can be adjusted to the braking width for a passability test. During adjustment, simply rotate the plate 21 to check the passability. Rotating button 52 causes threaded rod 51 to rotate, thus extending and retracting movable plate 23. This adjusts the distance between movable plate 23 and fixed plate 22. The desired width is determined by measuring with scale bar 4. When unfolding and fixing fixed width plate 1 and adjusting plate 2, they can be flipped to the same plane. At this time, the push of ejector spring 66 can drive movable block 65 to slide out, ultimately driving the end of fixed insertion rod 62 to insert into fixed insertion hole 61 to achieve the fixing purpose. Conversely, after pulling it out, fixed width plate 1 and adjusting plate 2 can be folded and fixed by magnetic fixing strip 3 for easy storage.
