[0029] The following describes embodiments of the present invention in detail. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0030] Reference below Figure 1-Figure 4 A braking device 1 according to an embodiment of the present invention is described. The braking device 1 can be installed on a vehicle and is used for braking the vehicle.

[0031] According to the first embodiment of the present invention, the braking device 1 of the vehicle is as follows: Figure 1 and Figure 2 As shown, the braking device 1 may include: a brake caliper 10, a mounting backplate 20, a friction plate 30 and a buffer structure 40. The brake caliper 10 is formed with a mounting groove 11. The mounting backplate 20 and the friction plate 30 are stacked and fixedly connected. The mounting backplate 20 is located between the bottom wall of the mounting groove 11 and the friction plate 30. The buffer structure 40 is fixed to the mounting backplate 20. The buffer structure 40 is opposite to the side surface 21 of the mounting backplate 20, and the buffer structure 40 corresponds to the side wall of the mounting groove 11.

[0032] It should be noted that in the related art, vehicles equipped with fixed brake calipers will produce abnormal metal impact noise when braking, affecting the driver's comfort.

[0033] Based on this, an embodiment of the present application proposes a braking device 1 for a vehicle, in which a brake caliper 10 can convert hydraulic energy into mechanical energy to generate braking force. The braking device 1 may include a brake disc 50, and the brake caliper 10 may be installed on the brake disc 50. When the driver steps on the brake pedal, the brake fluid may flow to the brake caliper 10 through the brake line, thereby pushing the piston in the brake caliper 10, and then pushing the friction plate 30 to abut against the brake disc 50, thereby achieving the purpose of braking deceleration or stopping. The brake caliper 10 is formed with a mounting groove 11, and the mounting groove 11 has two side walls that are opposite and spaced apart along a first direction. When the brake caliper 10 is as shown in FIG. Figure 1 When setting the direction, the first direction is Figure 1 The mounting back plate 20 can be fixedly connected to the friction pad 30 by means of a clamping connection, bolts, or the like. The mounting back plate 20 and the friction pad 30 are stacked and positioned between the bottom wall of the mounting groove 11 and the friction pad 30 along their arrangement. The mounting back plate 20 supports the friction pad 30 and transmits the braking force from the piston in the brake caliper 10, enabling the friction pad 30 to efficiently cooperate with the brake disc 50.

[0034] The buffer structure 40 can be fixed to the mounting back plate 20 by means of clamping, bonding, etc. The mounting back plate 20 is formed with two side surfaces 21 arranged opposite to each other along a first direction. The buffer structure 40 can be arranged on the side surface 21 of the mounting back plate 20. There can be two buffer structures 40, and the two buffer structures 40 can be respectively arranged on the two side surfaces 21 of the mounting back plate 20. The two buffer structures 40 can be respectively arranged corresponding to the side walls of the corresponding mounting groove 11. The buffer structure 40 can be located between the corresponding side surface 21 and the side wall of the corresponding mounting groove 11. The buffer structure 40 can isolate the side surface 21 of the mounting back plate 20 from the side wall of the mounting groove 11. The buffer structure 40 can play a role in buffering, reducing vibration, and reducing impact energy. The buffer structure 40 will not affect the matching assembly between the brake caliper 10 and the friction pad 30, nor the braking effect when the vehicle brakes.

[0035] When the vehicle brakes while moving forward or backward, the friction plate 30 twists and moves along the rotation direction of the brake disc 50, and the buffer structure 40 can contact the brake caliper 10. The buffer structure 40 can avoid direct collision between the mounting back plate 20 and the brake caliper 10, and can also reduce or eliminate the abnormal impact noise between the brake caliper 10 and the mounting back plate 20, which is conducive to improving the driver's comfort and improving customer satisfaction.

[0036] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the buffer structure 40 includes a buffer body 41 , and the buffer body 41 is wrapped around the edge of the mounting back plate 20 .

[0037] The buffer body 41 can be made of materials such as rubber and polyurethane. The buffer body 41 can provide cushioning, vibration reduction, and attenuation of impact energy. The buffer body 41 can be attached to the mounting backplate 20 by bonding, snapping, or other means. The buffer body 41 can cover the side surface 21 of the mounting backplate 20. The buffer body 41 can prevent the side surface 21 of the mounting backplate 20 from contacting the sidewalls of the mounting groove 11, thereby preventing the mounting backplate 20 from directly colliding with the brake caliper 10. The buffer body 41 can wrap around the edge of the mounting backplate 20 to reduce wear on the mounting backplate 20 during braking, thereby extending the service life of the mounting backplate 20.

[0038] In some embodiments of the present invention, Figure 4 As shown, the buffer body 41 is snap-connected to the mounting back plate 20 .

[0039] The buffer body 41 can be arranged on the mounting backplate 20 by a clip-on manner. As an example, a clip-on structure can be formed on the buffer body 41, and a clip slot 22 can be formed on the mounting backplate 20. The clip-on structure and the clip slot 22 are assembled in coordination so that the buffer body 41 is clipped to the mounting backplate 20, thereby ensuring that when the mounting backplate 20 collides with the brake caliper 10, the buffer body 41 will not fall off the mounting backplate 20, ensuring that the buffer body 41 can effectively slow down the vibration generated by the collision between the mounting backplate 20 and the brake caliper 10, attenuate the impact energy, and improve the comfort of the passengers.

[0040] In some embodiments of the present invention, Figure 3 and Figure 4 As shown, the buffer body 41 may include: a first body 411, a second body 412 and a third body 413, the second body 412 is connected between the first body 411 and the third body 413, the second body 412 is bent and connected to the first body 411 and the third body 413, and the first body 411 and the third body 413 are located on the same side of the second body 412, and the first body 411 and the third body 413 are respectively clamped on two opposite surfaces of the mounting backplate 20.

[0041] When the buffer body 41 is mounted on the mounting backplate 20, the first body 411 and the third body 413 are positioned opposite and spaced apart along the arrangement direction of the mounting backplate 20 and the friction plate 30. The second body 412 is connected between the first body 411 and the third body 413. The first body 411, the second body 412, and the third body 413 can be integrally formed. The first body 411 and the second body 412 are connected by a bend, forming an angle between the first body 411 and the second body 412. The angle can be a right angle or a similar angle. The third body 413 and the second body 412 are connected by a bend, forming an angle between the third body 413 and the second body 412. The angle can be a right angle or a similar angle. Along the first direction, the first body 411 and the third body 413 are located on the same side of the second body 412. Along the arrangement direction of the mounting backplate 20 and the friction plate 30, the two opposite surfaces of the mounting backplate 20 are provided with card grooves 22. The first body 411 and the third body 413 can be respectively clamped in the card grooves 22 on the two opposite surfaces of the mounting backplate 20, and the second body 412 can abut against the side surface 21 of the mounting backplate 20, thereby realizing the effect of clamping connection between the buffer body 41 and the mounting backplate 20, and realizing the effect of the buffer body 41 covering the edge of the mounting backplate 20.

[0042] In some embodiments of the present invention, Figure 4 As shown, two opposite surfaces of the mounting back plate 20 are provided with slots 22 , and the first body 411 and the third body 413 are respectively engaged in the corresponding slots 22 .

[0043] The mounting back plate 20 has two surfaces facing each other along the arrangement direction of the mounting back plate 20 and the friction plate 30, each of which is provided with a slot 22. The two slots 22 can be arranged opposite each other and recessed toward the interior of the mounting back plate 20. The first body 411 and the third body 413 can have the same structure, and the first body 411 and the third body 413 are respectively engaged in the corresponding slots 22. As an example, the first body 411 can be formed with a first flange 4111, which can be assembled with the corresponding slot 22, and the third body 413 can be formed with a second flange 4131, which can be assembled with the corresponding slot 22, thereby achieving the effect of the first body 411 and the third body 413 being respectively engaged in the corresponding slot 22. The first flange 4111 and the second flange 4131 can have the same structure, thereby simplifying the structure of the buffer body 41.

[0044] In some embodiments of the present invention, the buffer body 41 is bonded to the mounting back plate 20 .

[0045] The buffer body 41 can be connected to the mounting backplate 20 by bonding, so that the buffer body 41 is fixedly connected to the mounting backplate 20, which is beneficial to improve the connection strength between the buffer body 41 and the mounting backplate 20, prevent the buffer structure 40 from falling from the mounting backplate 20, and extend the service life of the buffer structure 40.

[0046] In some embodiments of the present invention, Figure 3 As shown, the buffer structure 40 may further include: a silencer body 42 , which is disposed between the side surface 21 of the mounting back plate 20 and the buffer body 41 .

[0047] The silencer body 42 can be constructed of materials such as rubber and silicone, effectively absorbing and reducing vibration and noise. The silencer body 42 can be sandwiched between the side surface 21 of the mounting backplate 20 and the buffer body 41. The silencer body 42 can be connected to the side surface 21 of the mounting backplate 20 by bonding or snapping. The silencer body 42 can also be connected to the buffer body 41 by bonding or snapping. The silencer body 42 can reduce or eliminate the impact noise between the mounting backplate 20 and the brake caliper 10, thereby improving passenger comfort and enhancing customer satisfaction.

[0048] In some embodiments of the present invention, the silencer body 42 is constructed as a silencer rubber pad, and the silencer body 42 is bonded to the side surface 21 of the mounting back plate 20 and the buffer body 41 .

[0049] The silencer body 42 can be constructed as a silencer rubber pad. The silencer body 42 can be tightly connected between the side surface 21 of the mounting back plate 20 and the buffer body 41 by bonding. The silencer body 42 can not only play a vibration reduction and noise reduction role, but also connect the mounting back plate 20 and the buffer body 41, thereby ensuring that the buffer body 41 will not fall off when the mounting back plate 20 and the brake caliper 10 collide, which is beneficial to extend the service life of the buffer structure 40 and improve the ability of the brake device 1 to reduce vibration and eliminate abnormal impact noise.

[0050] In some embodiments of the present invention, Figure 3 As shown, the muffler body 42 is constructed as a sheet-like structure.
