[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] Reference Figures 1-4 The present invention provides an embodiment of a brake friction pad wear alarm device, comprising a friction pad body 1, a fixing plate 6 and a brake disc 13, wherein a disassembly assembly is provided between the friction pad body 1 and the fixing plate 6, and a detection assembly is provided on the outside of the fixing plate 6. A first fixed cylinder 7 is fixedly connected to the side of the fixed plate 6. A second fixed cylinder 8 is slidably connected inside the first fixed cylinder 7. An extension rod 9 is slidably connected inside the second fixed cylinder 8. A movable plate 10 is fixedly connected to one end of the extension rod 9. A second contact 12 is fixedly connected to the side of the movable plate 10 near the fixed plate 6. A first contact 11 is fixedly connected to the side of the fixed plate 6 near the movable plate 10. The first contact 11 and the second contact 12 are electrically connected to each other to facilitate reminding the staff.

[0018] The disassembly assembly includes a fixing bolt 4, a groove 2 inside the friction plate body 1, a threaded groove 3 inside the groove 2, the fixing bolt 4 being threaded into the threaded groove 3, a connecting hole 5 inside the fixing plate 6, and one end of the fixing bolt 4 passing through the connecting hole 5; a drive ring 14 is fixedly connected to the outer wall of the brake disc 13, and the drive ring 14 is slidably connected to the moving plate 10; the moving plate 10 and the fixing plate 6 are parallel; two sets of first fixing cylinders 7 are symmetrically arranged; the first contact 11 and the second contact 12 correspond to each other; the brake disc 13 is parallel to the friction plate body 1, which facilitates uniform wear.

[0019] Working principle: In the brake friction pad wear alarm device, a controller is connected to the outside of the brake, so that the first contact 11 and the second contact 12 are both electrically connected to the controller. When the brake is used, the brake disc 13 performs friction braking on the friction pad body 1. The drive ring 14 moves with the movement of the brake disc 13, thereby driving the drive ring 14 to press the moving plate 10. This causes the moving plate 10 to drive the extension rod 9 to slide in the second fixed cylinder 8. The second fixed cylinder 8 slides in the first fixed cylinder 7, thereby driving the second contact 12 to approach the first contact 11, which facilitates the detection of the wear condition of the friction pad body 1. When the friction pad body 1 is worn to a certain extent, the second contact 12 contacts the first contact 11, thereby sending a signal to the controller. The controller triggers an alarm to remind the staff to replace and maintain the pad, thus enhancing safety. Unscrewing the fixing bolt 4 from the threaded groove 3 makes it easy to remove the fixing plate 6 from the friction pad body 1. This allows it to be installed on different friction pad bodies 1 for testing, making it more flexible and reusable multiple times.

The main controller can be a conventional known device such as a computer for control. The detailed description of known functions and known components is omitted in the specific embodiments disclosed herein.
