Description

Technical Field

[0001] This utility model relates to the technical field of power boosters, specifically to a brake booster that is easy to connect. Background Technology

[0002] A brake booster is an important component of a car's braking system. It enhances the force of the brake pedal, making it easier to apply braking force. In emergency braking situations, the brake booster can quickly increase the force applied by the driver, achieving a faster braking response. In critical moments, it can ensure that the braking system responds quickly, significantly reducing the possibility of accidents.

[0003] However, existing brake boosters mainly consist of a front housing and a rear housing. In actual use, the front and rear housings of the brake booster are connected by multiple sets of bolts. After prolonged use, some internal components of the brake booster will inevitably suffer varying degrees of damage. Therefore, it is necessary to disassemble the front and rear housings of the brake booster. Since there are many bolts connecting the front and rear housings, during maintenance, workers need to use external tools to disassemble multiple bolts one by one. The entire disassembly process is very inconvenient and will also affect the installation and use of the brake booster. Utility Model Content

[0004] The purpose of this invention is to provide a brake booster that is easy to connect, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a brake booster that is easy to connect, including a front housing, a rear housing detachably mounted on the front housing, and a diaphragm installed inside the front and rear housings.

[0006] An annular flange is integrally formed inside the front shell, and the annular flange is correspondingly and sealingly fitted with the rear shell;

[0007] Multiple positioning slots are arranged in a circular array on the side wall of the rear shell;

Each arc-shaped platform has an inclined guide area on its surface. Multiple locking elements are arranged in a circular array on the front shell. The locking operation between the front shell and the rear shell is completed by the cooperation of multiple locking elements and multiple positioning slots.

[0027] (1) This utility model is equipped with a drive mechanism, which drives the ring worm wheel and the synchronous ring to rotate through the meshing transmission of the worm and the ring worm wheel.

[0036] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0037] This utility model provides a technical solution: such as Figures 1 to 6 As shown, in this embodiment, the brake booster, which is easy to connect, includes a front housing 1, a rear housing 2 detachably mounted on the front housing 1, and a diaphragm 3 installed inside the front housing 1 and the rear housing 2.

[0038] An annular flange 4 is integrally disposed inside the front shell 1, and the annular flange 4 is correspondingly and sealingly fitted with the rear shell 2;

[0039] Multiple positioning slots 5 are arranged in a circular array on the side wall of the rear shell 2;

[0040] Synchronous ring 6 is rotatably sleeved on the outside of front shell 1. Multiple arc-shaped platforms 7 are arranged in a circular array on one side of synchronous ring 6. Each arc-shaped platform 7 has an inclined guide area 8 on its surface. The starting position of the inclined guide area 8 gradually approaches the center of front shell 1 from the end position. Multiple locking elements are arranged in a circular array on front shell 1. The locking operation between front shell 1 and rear shell 2 is completed by the cooperation of multiple locking elements and multiple positioning grooves 5.

[0041] The drive mechanism, mounted on the front housing 1, performs the control operation of the synchronization loop 6.

[0042] The protective mechanism is set on the annular flange 4 and the front shell 1 to complete the sealing operation;

[0043] Multiple guide rails 9 are arranged in a circular array on the inner wall of the front shell 1, and multiple positioning protrusions 10 are arranged in a circular array around the rear shell 2. The multiple positioning protrusions 10 are correspondingly slidably engaged with the multiple guide rails 9.

[0044] Each locking element includes:

[0045] The positioning rod 11 is slidably inserted into the front shell 1. The positioning rod 11 is inserted into the positioning groove 5 to complete the locking. A ball bearing that cooperates with the inclined guide area 8 is provided on the top of the positioning rod 11.

[0046] A positioning spring 12 is provided between the positioning rod 11 and the front housing 1 for resetting;

[0047] An annular worm gear 13 is integrally provided on one side of the synchronization ring 6, and the annular worm gear 13 is configured to cooperate with the drive mechanism.

[0048] like Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the drive mechanism includes:

[0049] The worm gear 14 is rotatably mounted on the front housing 1 via a bracket, and the worm gear 14 is engaged with the annular worm wheel 13.

[0050] The first handle is located at one end of the worm gear 14;

[0051] The drive mechanism also includes:

[0052] A guide frame 15 is set on one side of the worm gear 14. A locking arm 16 is slidably engaged on the guide frame 15. A meshing tooth that engages with the annular worm gear 13 is provided at the bottom of the locking arm 16.

[0053] The adjusting screw 17 is threaded onto the guide frame 15, and the bottom of the adjusting screw 17 is rotatably connected to the locking arm 16. A second handle is installed on the top of the adjusting screw 17.

[0054] like Figure 6 As shown, the protective mechanism includes:

[0055] An annular cavity 18 is hidden on the annular flange 4;

[0056] The compression chamber 19 is located on one side of the front shell 1. One end of the compression chamber 19 is open. A compression rod 20 is slidably and sealed inside the compression chamber 19. The compression rod 20 and the compression chamber 19 cooperate to complete the compression action. One end of the compression rod 20 extends into the compression chamber 19. The piston compression action is completed by the cooperation of the compression rod 20 and the compression chamber 19, which is beneficial to the sealing operation of the subsequent protective mechanism. The compression rod 20 is connected to the synchronization ring 6. The compression chamber 19 is connected to the annular bladder 18 through a pipe. A certain amount of gas medium is filled in the compression chamber 19. The expansion of the annular bladder 18 is used for the sealing treatment of the front shell 1 and the rear shell 2.

[0057] It should be noted that: under the synchronous action of the drive mechanism, the synchronous ring 6 moves accordingly. During the movement of the synchronous ring 6, the compression rod 20 moves in conjunction with the compression chamber 19, compressing the gas medium in the compression chamber 19 into the annular cavity 18. This causes the annular cavity 18 to expand and fill the space between the annular flange 4 and the rear shell 2, thus completing the sealing process and further improving the sealing performance of the front shell 1 and the rear shell 2.

[0058] This utility model provides a brake booster that is easy to connect. Its specific working principle is as follows: First, the front shell 1 and rear shell 2 are brought close together. Then, the rear shell 2 is pushed towards the front shell 1 until it is in contact with the annular flange 4. The guide rail 9 and positioning protrusion 10 ensure precise guidance during assembly of the rear shell 2 and front shell 1, facilitating subsequent locking operations. A drive mechanism allows the installer to rotate the first handle, causing the worm gear 14 to rotate. Through the meshing transmission between the worm gear 14 and the annular worm wheel 13, the annular worm wheel 13 and the synchronizing ring 6 rotate accordingly. The synchronizing ring 6 moves synchronously with multiple arc-shaped platforms 7. Under the pressure of the inclined guide area 8, it pushes the positioning rod 11 to overcome the positioning spring 12 and insert it into the positioning groove 5. Thus, the synchronizing ring 6 completes the synchronous locking of multiple locking components, simultaneously achieving… The multi-point locking design of the front shell 1 and rear shell 2 improves the connection stability between them. The use of a synchronous ring 6 and drive mechanism optimizes the traditional disassembly process by eliminating the need to remove multiple bolts, improving installation efficiency. It also enables active and precise positioning guidance, reducing installation difficulty. A protective mechanism is included. Under the synchronous action of the drive mechanism, the linkage compression rod 20 moves within the compression chamber 19, compressing the gas medium within the chamber into the annular cavity 18. This causes the annular cavity 18 to expand and fill the space between the annular flange 4 and the rear shell 2, completing the sealing process and further enhancing the sealing performance of the front shell 1 and rear shell 2. The optimized structural design allows for quick assembly and disassembly of the front shell 1 and rear shell 2, providing optimized sealing and ensuring stable operation of the brake booster, thus extending its service life.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
