Description

Technical Field

[0001] The utility model belongs to the technical field of automobile brake systems, and in particular relates to a brake pad structure. Background Art

[0002] In traditional braking systems, brake pads are one of the key components to ensure that vehicles can be effectively decelerated and stopped. Brake pads slow down vehicles by contacting and rubbing against brake discs. However, during the braking process, the friction between the brake pads and the brake discs will generate a large amount of debris. If these debris are not removed in time, they will accumulate in the braking system, affecting the braking effect and may even cause brake failure, thus posing a safety hazard.

[0003] In addition, the performance of traditional brake pads will significantly decrease after they are worn to a certain extent, but it is often difficult for drivers to detect it in time. Although some brake systems are equipped with wear warning functions, these functions are usually implemented through simple wear marks or electronic sensors, which not only increases costs, but may also be unstable due to environmental factors and sensor failures. Utility Model Content

[0004] In view of the problems existing in the prior art, the utility model aims to provide a brake pad structure, which can not only relieve the friction during braking, but also generate vibrations through friction with the brake disc when the friction block is worn to a preset warning value. This vibration is amplified by a speaker at the end of the vibration plate, thereby emitting a sound to warn the driver.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A brake pad structure, comprising a back plate, a friction block connected to one side of the back plate, a muffler connected to the other side of the back plate, a connecting fastener plugged into the side of the back plate, and the muffler located between the back plate and the connecting fastener;

[0007] The connecting fastener includes a connecting plate, both ends of the connecting plate are fixedly connected with positioning springs, and the top of the connecting plate is fixedly connected with a vertical plate, the top of the vertical plate is connected with a flat plate, the top of the flat plate is plugged with a speaker, and a vibration plate is plugged on the flat plate, and one end of the vibration plate is located in the speaker.

[0008] Furthermore, a socket is fixedly connected to the center of the top of the tablet, a plug-in tube is fixedly connected to the bottom of the speaker, and the plug-in tube is sleeved on the socket.

[0009] Furthermore, the shape of the vibration plate is set to be L-shaped, and a nesting piece is sleeved on the vibration plate, and the nesting piece is inserted into the socket.

[0010] Furthermore, a material guide groove is provided on the side of the friction block, and the material guide grooves are distributed at equal intervals along the height direction of the friction block.

[0011] Furthermore, claws are fixedly connected to both ends of the back plate, and a first limiting groove and a second limiting groove are opened on one side of the back plate.

[0012] Furthermore, a plug-in column and a positioning block are fixedly connected to the other side of the back plate, and a positioning hole and a through groove corresponding to the plug-in column and the positioning block are respectively opened on the side surface of the sound-absorbing plate.

[0013] Furthermore, a locking window is formed through the side surface of the connecting plate, and the positioning block is inserted into the locking window.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] First, through the coordinated design of the vibration plate and the speaker, the brake pad structure of the utility model can effectively warn the driver when the friction block wear reaches the preset warning value. The vibration plate generates vibration during the contact friction with the brake disc, and this vibration is amplified by the speaker, thereby issuing a warning sound to promptly inform the driver of the wear of the brake pad. This design not only improves driving safety, but also extends the overall life of the brake system.

[0016] Secondly, the utility model effectively collects and discharges the debris generated during the braking process by setting a guide groove on the side of the friction block. This design keeps the brake system clean, prevents the accumulation of debris from affecting the braking effect, and solves the problem of reduced braking performance and potential safety risks caused by the accumulation of debris in traditional brake systems.

[0017] In addition, the utility model provides a simple assembly and maintenance method through the design of the socket and the plug tube, and the configuration of the nested parts on the vibration plate. This design not only ensures the stability and durability of each component, but also facilitates the rapid replacement of key components such as the vibration plate when necessary, thereby improving maintenance efficiency and economy.

When the friction block 2 is worn to a preset warning value, the vibration plate 46 vibrates through friction with the brake disc, and the sound is amplified through the speaker 45 to effectively warn.

[0032] See also Figure 5-6A socket 441 is fixedly connected to the top center of the flat plate 44. The design of the socket 441 makes the installation and replacement of the vibration plate 46 more convenient; a plug-in tube 451 is fixedly connected to the bottom of the speaker 45. The plug-in tube 451 is sleeved on the socket 441. Through this structural setting, the coordinated work of the speaker 45 and the vibration plate 46 is ensured, and the stability and reliability of the warning effect are enhanced.

[0033] See also Figure 5-6 The shape of the vibration plate 46 is set to be L-shaped, which increases the contact area with the brake disc and improves the friction efficiency; and a nesting piece 461 is sleeved on the vibration plate 46, and the nesting piece 461 is inserted into the socket 441. This design not only ensures the stability of the vibration plate 46 during operation, but also facilitates maintenance and replacement.

[0034] See also Figure 1 A material guide groove 21 is provided on the side of the friction block 2. The material guide grooves 21 are evenly spaced along the height direction of the friction block 2, which effectively collects and guides out the debris generated during the braking process, maintains the cleanliness of the brake pad and the overall performance of the brake system.

[0035] See also Figure 1-3 Both ends of the back plate 1 are fixedly connected with claws 11 for fixing the brake pads in the brake device; and a first limiting groove 12 and a second limiting groove 13 are opened on one side of the back plate 1.

This structural design not only increases the bonding strength between the connecting plate 41 and the back plate 1, but also facilitates assembly and disassembly, thereby improving maintenance efficiency.

[0038] The working principle of the utility model is:

[0039] When in use, the nesting piece 461 needs to be inserted into the socket 441, and then the plug tube 451 is sleeved on the socket 441, and the bottom end of the vibration plate 46 is facing the position of the friction block 2;

[0040] When the friction block 2 is in contact with the brake disc, the generated debris will fall into the guide groove 21, so as to avoid the debris falling during the braking process from affecting the braking effect;

[0041] When the friction block 2 is gradually worn out over time and reaches a preset warning value, when the brakes are applied again, one end of the vibration plate 46 will rub against the brake disc, causing the vibration plate 46 to vibrate during the friction process. Since one end of the vibration plate 46 is located in the speaker 45, the sound of the vibration of the vibration plate 46 will be amplified by the speaker 45, thereby warning the driver and allowing him to promptly understand the usage of the brake pads.

[0042] The above is only a preferred embodiment of the present invention. It should be noted that, for ordinary technicians in the technical field, several improvements and modifications can be made without departing from the principle of the present invention, and these improvements and modifications should also be regarded as the protection scope of the present invention. The structures, devices and operating methods not specifically described and explained in the present invention shall be implemented according to the conventional means in the field unless otherwise specified and limited.
