Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to an automobile brake pad which is easy to replace. Background Art

[0002] Automobile brake pads are crucial components in the automobile braking system. Brake pads are usually composed of friction materials, backing plates and adhesives. Their main function is to convert the car's kinetic energy into heat energy through friction with the brake disc, thereby achieving vehicle deceleration and parking. Brake pads have good friction properties and can provide stable and sufficient friction at different vehicle speeds, temperatures, humidity, etc., to ensure rapid and effective braking. Different types of brake pads are suitable for different driving needs and vehicle types. High-performance brake pads are more suitable for sports cars and intense driving, while ordinary brake pads can meet the needs of daily driving. Brake pads are one of the key components to ensure driving safety. During use, the brake pads will gradually become thinner due to wear.

[0003] The conventional installation method of automobile brake pads makes it difficult to disassemble them after long-term use. Currently, when replacing brake pads, the entire brake pad needs to be disassembled, which is usually troublesome and not only consumes a lot of man-hours but is also very laborious. Summary of the invention

By pressing the locking switch to drive the limit block to leave the limit hole in the brake pad back plate, the brake pad back plate and the brake pad body can be taken out from the mounting frame. This structure can quickly disassemble and assemble the brake pad body from the mounting frame, thereby facilitating the replacement of the brake pad. The quick disassembly of the brake pad brings great convenience to the repair and maintenance of the vehicle, shortens the repair time, and correspondingly reduces the labor cost.

[0005] To achieve the above-mentioned purpose, the utility model also provides the above-mentioned easy-to-replace automobile brake pad, including: a mounting frame, a fixing block is fixedly connected to the upper surface of the mounting frame, a first groove is arranged inside the fixing block, a second groove is arranged inside the fixing block, a spring is fixedly connected to the right inner wall of the first groove, a locking switch is fixedly connected to the left end of the spring, a connecting rod is fixedly connected to the right surface of the locking switch, a limiting block is fixedly connected to the right surface of the connecting rod, a mounting groove is arranged inside the fixing block, a brake pad back plate is slidably connected to the inner surface of the mounting groove, a limiting hole is arranged inside the brake pad back plate, and a brake pad body is fixedly connected to the front surface of the brake pad back plate.

[0006] There are two fixing blocks distributed on the left and right. A third groove is provided inside the brake pad body. The third groove increases the surface area of ​​the brake pad body, which helps to dissipate heat faster during braking, prevents the brake pad from reducing braking performance due to overheating, and extends the service life of the brake pad. Friction debris generated during braking can be discharged through the third groove to avoid debris accumulation and affect the braking effect.

[0007] The first groove is communicated with the second groove, and the second groove is communicated with the limiting hole.

[0008] The side surface of the limit block is slidably connected to the limit hole, and the side surface of the limit block is slidably connected to the brake pad back plate. By pressing the locking switch, the connecting rod and the limit block are driven to move, and the limit block leaves the limit hole.

[0009] The side surface of the limit block is slidably connected to the second groove, and the side surface of the limit block is slidably connected to the fixed block. By pressing the locking switch, the connecting rod and the limit block are driven to move, and the limit block leaves the limit hole to the second groove and the first groove.

[0010] The number of the spring, locking switch, connecting rod and limit block are two and they are distributed on the left and right. The rear surface of the brake pad back plate is fixedly connected to a silencer, which effectively absorbs and reduces the vibration and friction noise generated when the brake pad contacts the brake disc, providing a quieter driving environment, while reducing the impact of vibration on other components of the brake system, reducing the risk of component damage, and extending the overall service life of the brake system.

[0011] The surface of the brake pad body is provided with a high temperature resistant coating, and the surface of the brake pad body is provided with a corrosion resistant coating, which can reduce the thermal decay of the brake pad and maintain stable braking performance under high temperature braking conditions.
