Description

Technical Field

[0001] This utility model relates to the field of brake caliper technology, and in particular to a hydraulic disc brake caliper. Background Technology

[0002] Brake calipers are an important component of a car's braking system. Their main function is to achieve vehicle braking by clamping the brake disc.

[0003] Currently, existing brake calipers (such as patent publication number: CN218207554U) disclose a hydraulic brake caliper. The end face of the housing has an observation port that facilitates observation and improves heat dissipation. The end face of the housing is provided with a limiting unit connected to it and used to limit the position of the friction pad in the caliper body. The above structure facilitates the observation of friction pad wear without disassembling the housing and also ensures heat dissipation during operation.

[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: the side of the caliper is hollowed out. During the movement of the car, high-speed flying gravel will enter the caliper. The gravel will cause impact damage to the caliper surface and friction block, affecting the stability of braking. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides a hydraulic disc brake caliper that solves the technical problem that high-speed flying gravel during vehicle movement can cause impact damage to the caliper surface and friction blocks, affecting braking stability.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A hydraulic disc brake caliper includes a caliper body, a mounting plate fixedly installed on the side end of the caliper body, a protective plate fixedly installed inside the mounting plate, at least two openings inside the protective plate, a guide plate rotatably installed inside each opening, and two intercepting plates fixedly installed on the outer side of the protective plate.

[0010] Preferably, the caliper body has two first fixing blocks fixedly installed inside, each first fixing block has a limit groove on its side end, each caliper body has a second fixing block fixedly installed inside, each protective plate has two elastic plates fixedly installed on its side end, the protective plate has bolts rotatably installed on its side end, and at least two positioning pins are fixedly installed on the inner side of the mounting plate.

[0011] (III) Beneficial Effects

[0012] 1. By rotating the bolt, the bolt is rotated in the forward direction at the side end of the protective plate, and the end of the bolt is rotated into the interior of the second fixing block. The rotation of the bolt pushes the mounting plate and the caliper body to press and fix each other. By installing the mounting plate and the protective plate on the side end of the caliper body, two intercepting plates are installed on the side end of the protective plate, which play a role in shielding and protecting the side end of the caliper body to prevent flying debris from entering the interior of the caliper body and affecting the braking performance of the caliper body.

[0013] 2. By rotating the bolt in the opposite direction, the bolt is rotated away from the interior of the second fixing block. At the same time, the mounting plate is pulled, allowing it to slide on the side of the caliper body. Simultaneously, the protective plate causes the two elastic plates to rub against the side of the first fixing block, squeezing and bending the elastic plates, causing the protrusions at the top of the elastic plates to leave the interior of the limiting groove. At the same time, the mounting plate causes the positioning pin to slide away from the interior of the caliper body on the side. The bolt and elastic plates facilitate quick installation of the mounting plate. Attached Figure Description

[0020] This application provides a hydraulic disc brake caliper that effectively solves the problem of high-speed flying gravel causing impact damage to the caliper surface and friction blocks during vehicle movement, affecting braking stability. By rotating the bolt, the bolt rotates forward at the side end of the protective plate, rotating the end of the bolt into the interior of the second fixing block. Through the rotation of the bolt, the mounting plate and the caliper body are pressed and fixed together. By installing the mounting plate and the protective plate on the side end of the caliper body, and installing two intercepting plates on the side end of the protective plate, the side end of the caliper body is shielded and protected, preventing flying gravel from entering the interior of the caliper body and affecting the braking performance of the caliper body.

[0021] Example

[0022] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the technical solution in this application embodiment effectively solves the technical problem that high-speed flying gravel during vehicle movement causes impact damage to the caliper surface and friction blocks, affecting braking stability. The overall idea is as follows:

[0023] To address the problems existing in the prior art, this utility model provides a hydraulic disc brake caliper, including a caliper body 11. A mounting plate 12 is fixedly installed on the side end of the caliper body 11. A protective plate 13 is fixedly installed inside the mounting plate 12. The protective plate 13 has at least two openings 21 inside, and a guide plate 22 is rotatably installed inside each opening 21. Two intercepting plates 23 are fixedly installed on the outside of the protective plate 13. By rotating a bolt 14, the bolt 14 is rotated forward at the side end of the protective plate 13, and the end of the bolt 14 is rotated into the interior of a second fixing block 17. Through the rotation of the bolt 14, the mounting plate 12 and the caliper body 11 are pushed to press and fix each other. By installing the mounting plate 12 and the protective plate 13 on the side end of the caliper body 11, and installing two intercepting plates 23 on the side end of the protective plate 13, the side end of the caliper body 11 is shielded and protected.

[0024] Two first fixing blocks 16 are fixedly installed inside the caliper body 11. Each first fixing block 16 has a limit groove 15 on its side end. A second fixing block 17 is fixedly installed inside the caliper body 11. Two elastic plates 19 are fixedly installed on the side end of each protective plate 13. Bolts 14 are rotatably installed on the side end of the protective plate 13. At least two positioning pins 18 are fixedly installed on the inner side of the mounting plate 12. A guide plate 22 is installed inside the opening 21. Airflow can enter the interior of the caliper body 11 through the opening 21. The airflow pushes the guide plate 22 to rotate. The guide plate 22 guides the airflow to the side end of the first fixing block 16. Two oblique grooves are opened inside the first fixing block 16. The airflow enters the interior of the first fixing block 16 through the guide plate 22, and then the first fixing block 16 directs the airflow to the friction block to cool the caliper body 11 and the friction block.

[0025] Working principle:

[0026] In the first step, during use, the mounting plate 12 and the protective plate 13 are an integral structure. Move the mounting plate 12 to align its side end with the caliper body 11. By pushing the mounting plate 12, the positioning pin 18 is inserted into the side end of the caliper body 11. An insertion hole is provided on the side end of the caliper body 11, and the positioning pin 18 enters the hole to facilitate the positioning and installation of the mounting plate 12. By rotating the bolt 14, the bolt 14 rotates forward on the side end of the protective plate 13, rotating the end of the bolt 14 into the interior of the second fixing block 17. The rotation of the bolt 14 pushes the mounting plate 12 and the caliper body 11 together, pressing and fixing them in place. By installing the mounting plate 12 and the protective plate 13 on the side end of the caliper body 11, the caliper body is protected... Two interceptor plates 23 are installed on the side of the guard plate 13, which serve to shield and protect the side of the caliper body 11, preventing flying debris from entering the interior of the caliper body 11 and affecting the braking performance of the caliper body 11. At the same time, multiple openings 21 are provided on the side of the guard plate 13, and guide plates 22 are installed inside the openings 21. Airflow can enter the interior of the caliper body 11 through the openings 21. The airflow pushes the guide plates 22 to rotate, and the guide plates 22 guide the airflow to the side of the first fixing block 16. The first fixing block 16 has two oblique grooves inside. The airflow enters the interior of the first fixing block 16 through the guide plates 22, and then the first fixing block 16 directs the airflow to the friction block, cooling the caliper body 11 and the friction block.

[0027] In the second step, during the simultaneous installation of the mounting plate 12, after the caliper body 11 is aligned with the mounting plate 12, two elastic plates 19 are installed inside the protective plate 13. The elastic plates 19 have a certain degree of elasticity, and a protrusion is installed at the top of the elastic plate 19. The elastic plate 19 presses against the side end of the first fixing block 16, causing the elastic plate 19 to bend. At the same time, the protrusion at the top of the elastic plate 19 engages with the interior of the limiting groove 15, facilitating the quick installation of the mounting plate 12. By rotating the bolt 14 in the opposite direction, the bolt 14 is rotated away from the mounting plate 12. Open the interior of the second fixing block 17 and pull the mounting plate 12 to slide the mounting plate 12 on the side of the caliper body 11. At the same time, the protective plate 13 drives the two elastic plates 19 to rub against the side of the first fixing block 16, squeezing the elastic plates 19 to bend and deform, so that the protrusion at the top of the elastic plate 19 leaves the interior of the limiting groove 15. At the same time, the mounting plate 12 drives the positioning pin 18 to slide away from the interior of the caliper body 11 on the side. The mounting plate 12 can be quickly installed by the bolt 14 and the elastic plate 19.

[0028] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
