[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a modular brake assist device, including a shell 1, which is the main structure of the entire brake assist device and is used to support and install the entire friction component 2 and the extrusion component 3. The friction component 2 is arranged inside the shell 1, and the friction component 2 includes a positioning column 21, which is fixedly connected to the inner wall of the shell 1. The positioning columns 21 are symmetrically arranged in two groups, and the outer walls of the two groups of positioning columns 21 are fixedly connected with baffles 22. The baffles 22 and the limiting protrusions 25 are used to limit the movement range of the mounting plate 23 to prevent it from falling off the surface of the positioning column 21 under the elastic force of the support spring 28. The outer wall of the positioning column 21 is slidably connected with two groups of symmetrically arranged mounting plates 23, and the side walls adjacent to the mounting plates 23 are fixedly connected with brake pads 24. The mounting plates 23 are used to install and fix the brake pads 24, and the brake pads 24 are used to rub against the side walls of the brake disc to play a role in deceleration.

[0030] Reference Figure 3The end of the positioning column 21 is fixedly connected with a limiting protrusion 25, and the side wall of the mounting plate 23 is provided with a plurality of positioning holes 26 arranged in an array. The limiting protrusion 25 is used to cooperate with the positioning hole 26 to attach and position the brake pad 24, thereby ensuring the stability of the brake pad 24 during use. A positioning pin 27 is inserted into the positioning hole 26, and the positioning pin 27 is fixedly connected to the side wall of the brake pad 24. The two groups of mounting plates 23 are elastically connected by a support spring 28. The support spring 28 is used to play the role of elastic support for the two groups of mounting plates 23, so that the two groups of mounting plates 23 can drive the brake pad 24 away from the brake disc when being squeezed by external force.

[0031] Reference Figure 1 - Figure 2 The side wall of the housing 1 is provided with an extrusion component 3, and the main function of the extrusion component 3 is to apply force during braking to make the brake pad 24 in close contact with the brake disc, thereby achieving an effective braking effect. The extrusion assembly 3 includes a fixing seat 31, which is fixedly connected to the side wall of the shell 1. The side wall of the fixing seat 31 is provided with a through hole, and a rotating shaft 32 is inserted in the through hole. The rotating shaft 32 communicates with the internal and external parts of the shell 1 to transmit power. One end of the rotating shaft 32 is fixedly connected to a bolt 33, and the bolt 33 is used to be inserted into the polygonal positioning hole 38 and meshed therewith to achieve synchronous rotation of the rotating plate 37 and the rotating shaft 32. The other end of the rotating shaft 32 is fixedly connected to a threaded column 34, and the end of the bolt 33 is fixedly connected to a threaded telescopic rod 35. The outer wall of the threaded telescopic rod 35 is threadedly connected to a pressing block 36. A rotating plate 37 is sleeved on the outer wall of the threaded telescopic rod 35, and the rotating plate 37 is pressed toward the side wall of the shell 1 by the pressing block 36. The position of the rotating plate 37 is fixed, but it can be rotated. The rotation of the rotating plate 37 realizes the rotation of the rotating shaft 32 and the threaded column 34.

[0032] Reference Figure 2 , a polygonal positioning opening 38 is provided on the surface of the rotating plate 37, and the polygonal positioning opening 38 is meshed with the bolt 33. The outer wall of the threaded column 34 is threadedly connected with a sleeve 39, and the sleeve 39 is fixedly connected to the inner wall of the fixing seat 31. The end of the sleeve 39 is provided with a through hole, and an extrusion rod 310 is inserted in the through hole. The position of the sleeve 39 is relatively fixed, and the threaded column 34 moves toward the inside of the sleeve 39. The threaded telescopic rod 35 is extended, and the threaded column 34 applies pressure to the extrusion rod 310. The end of the extrusion rod 310 is fixedly connected with a pressure seat 311, and the pressure seat 311 is used to apply pressure to the mounting plate 23. The rotating plate 37 and the outer wall of the housing 1 are elastically connected by a return spring 312. It is used to help the rotating plate 37 quickly return to its original position after rotation.

[0033] Working principle: When the braking operation needs to be performed, first, the external power source is started to transfer the force to the extrusion assembly 3. At this time, the rotating plate 37 starts to rotate at a small angle, and the close engagement of the bolt 33 and the polygonal positioning port 38 ensures the synchronous rotation of the rotating plate 37 and the rotating shaft 32, thereby driving the mechanical linkage inside the entire extrusion assembly 3. As the rotating shaft 32 rotates, the threaded column 34 gradually moves forward in the sleeve 39. Due to the threaded connection between the two, the threaded telescopic rod 35 extends under the push of the threaded column 34. As the threaded telescopic rod 35 continues to extend, the pressure is finally transmitted to the mounting plate 23 through the pressure seat 311. After receiving the thrust from the pressure seat 311, the mounting plate 23 overcomes the elastic force of the support spring 28 and moves toward the brake disc. In this process, the brake pad 24 is tightly attached to the side wall of the brake disc, generating a strong friction force, thereby achieving the deceleration or stop of the vehicle. The contact pressure and friction between the brake pad 24 and the brake disc can be precisely controlled by adjusting the elongation of the threaded telescopic rod 35. In addition, the cooperation between the positioning hole 26 and the positioning pin 27, as well as the limitation of the movement range of the mounting plate 23 by the limiting protrusion 25, together ensure the stability and reliability of the brake pad 24 during the braking process. When the braking operation is completed, the external power source is withdrawn, and the reset spring 312 begins to work, pushing the rotating plate 37 back to its original position. At the same time, the threaded column 34 rotates in the opposite direction and retracts in the sleeve 39, driving the threaded telescopic rod 35 to shorten, and finally separating the pressure seat 311 from the mounting plate 23. The brake pad 24 returns to its original state under the elastic force of the support spring 28, ready for the next braking operation.

[0034] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
