The vacuum booster is a component that uses vacuum to increase the force applied by the driver to the pedal, making it easier for the driver to apply force to the pedal and making the pedal easier to control. After the vacuum booster assembly is installed, it needs to be fixed using the vacuum booster assembly fixing structure to ensure the stability of the vacuum booster assembly.
[0003] The patent application with publication number CN208469775U discloses a vacuum booster assembly fixing structure. This technical solution utilizes two locking wheels to realize the four-point fixed assembly requirements of the vacuum booster with brake master cylinder assembly, avoiding the problem of insufficient assembly space, facilitating assembly, improving assembly efficiency and assembly quality, and solving the problem that the vacuum booster with brake master cylinder assembly of this light passenger vehicle is fixed to the front panel of the cockpit by four fixing bolts on the vacuum booster through fixing nuts. Due to the small space in the cockpit, the two fixing nuts on the left are at a small distance from the steering column, and the steering column is just in front of the fixing nuts, so that the two fixing nuts on the left cannot be assembled and tightened with a sleeve, making it very difficult to assemble and disassemble the two fixing nuts at this location, affecting assembly efficiency and assembly quality.

[0033] The utility model is further described in detail below in conjunction with the accompanying drawings.
[0034] Reference Figure 1-4 , which is a vacuum booster assembly fixing structure disclosed in the utility model, includes a vacuum booster assembly body 1, a bolt 2, a nut 3 and a rotatable fixing component 4, the bottom surface of the vacuum booster assembly body 1 is fixedly equipped with a bolt 2, the nut 3 is connected to the bolt 2 through a thread, the vacuum booster assembly body 1 is penetrated into the rotatable fixing component 4, the bolt 2 is fixedly penetrated into the rotatable fixing component 4, and the nut 3 is clamped with the rotatable fixing component 4.
[0035] The vacuum booster assembly 1 is a component that can use vacuum to increase the force applied by the driver to the pedal. The bolt 2 is welded to the bottom of the vacuum booster assembly 1. The bolt 2 is aligned with the rotatable fixing component 4 and inserted into the rotatable fixing component 4. The vacuum booster assembly 1 is placed on the rotatable fixing component 4. The nut 3 is then screwed onto the bolt 2 and the nut 3 is tightened. The nut 3 is fixedly connected to the bolt 2, and the top of the rotatable fixing component 4 can be fixed between the vacuum booster assembly 1 and the nut 3. The rotatable fixing component 4 is then sleeved on the outside of the nut 3 to fix the nut 3 and prevent it from loosening.
[0036] Reference Figure 2-4 The rotatable fixing component 4 of this embodiment includes a top plate 401, and a through hole 402 and a slot 403 are opened on the top of the top plate 401. The rotatable fixing component 4 includes a telescopic ring 404, and the fixed end of the telescopic ring 404 is fixedly mounted on the bottom surface of the top plate 401. The rotatable fixing component 4 includes a lifting ring 405, and the lifting ring 405 is movably mounted in the telescopic ring 404. A clamping block 406 is fixedly mounted on the lifting ring 405. The rotatable fixing component 4 includes a limit block 407, and the limit block 407 is fixedly connected to the lifting ring 405. The rotatable fixing component 4 includes a limit ring 408, and the limit ring 408 is clamped in the limit block 407. The two ports of the limit ring 408 are respectively fixedly mounted with an upper limit piece 409 and a lower limit piece 410.
[0037] It is stipulated that the extension direction of the telescopic ring 404 is below the rotatable fixed component 4, and the contraction direction of the telescopic ring 404 is above the rotatable fixed component 4. The vacuum booster assembly 1 is placed above the top plate 401, and the bolt 2 is inserted into the penetration hole 402 from the top of the top plate 401. The bolt 2 extends from the bottom of the top plate 401. The nut 3 is screwed onto the bolt 2, and the nut 3 is tightened. The nut 3 is fixedly connected to the bolt 2, so that the top plate 401 can be fixed between the vacuum booster assembly 1 and the nut 3, and the vacuum booster assembly 1 can be fixed.
[0038] By rotating the lifting ring 405, the lifting ring 405 drives the clamping block 406 and the limit block 407 to rotate, the limit block 407 drives the limit ring 408 to rotate, and the limit ring 408 drives the upper limit plate 409 and the lower limit plate 410 to rotate. When the clamping block 406 is aligned with the clamping groove 403 and the limit ring 408 is aligned with the bolt 2, the lifting ring 405 is stopped, and by pressing the telescopic ring 404, the telescopic ring 404 drives the lifting ring 405 to move upward, the lifting ring 405 drives the clamping block 406 and the limit block 407 to move upward, the limit block 407 drives the limit ring 408 to move upward, and the limit ring 408 drives the upper limit plate 409 and the lower limit plate 410 to move upward, and the bolt 2 is penetrated by the limit ring 408, the upper limit plate 409 and the lower limit plate 410.
[0039] When the upper limit plate 409 contacts the nut 3, the nut 3 is clamped in the upper limit plate 409 and the limiting ring 408. The holes formed on the limiting ring 408 and the upper limit plate 409 are consistent with the external shape of the nut 3. The edges and corners of the hole formed on the lower limit plate 410 are consistent with the edges and corners of the limiting ring 408, but the diameter is smaller than the hole diameter of the limiting ring 408 and is larger than the diameter of the bolt 2. When the edges and corners of the holes on the upper limit plate 409 and the limiting ring 408 are not aligned with the edges and corners of the outer wall of the nut 3, by rotating the lower limit plate 410, the lower limit plate 410 drives the limiting ring 408 to rotate, and the limiting ring 408 drives the upper limit plate 409 to rotate. When the edges and corners of the holes on the lower limit plate 410 are aligned with the edges and corners of the outer wall of the nut 3, the edges and corners of the holes on the upper limit plate 409 and the limiting ring 408 are aligned with the edges and corners of the outer wall of the nut 3.
[0040] By continuing to push the lifting ring 405 to drive the limiting ring 408, the limiting ring 408 can be sleeved on the outer wall of the nut 3, and the clamping block 406 can be clamped in the clamping groove 403. The triangular structure on the clamping block 406 can make the clamping block 406 and the clamping groove 403 fixedly connected. The clamping block 406 is fixed to drive the lifting ring 405 to be fixed, the lifting ring 405 drives the limiting block 407 to be fixed, and the limiting block 407 drives the limiting ring 408 to be fixed, which can prevent the limiting ring 408 from moving downward. 8 can prevent the lower limit plate 410 from moving downward. If the nut 3 is loose, it will rotate and move downward on the bolt 2. The nut 3 will drive the limit ring 408 and the lower limit plate 410 to rotate and move downward. The limit ring 408 and the lower limit plate 410 are fixed and cannot move downward, so the nut 3 is fixed and cannot move downward and rotate, which can prevent the nut 3 from loosening. The four groups of limit rings 408, upper limit plates 409 and lower limit plates 410 can rotate independently and can fix the four nuts 3 respectively.
[0041] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
