DETAILED DESCRIPTION

[0021] The technical scheme in the embodiments of the utility model will be described clearly and completely below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative work fall within the protection scope of the utility model.

[0022] As Figure 1 and Figure 2 The utility model provides a technical scheme of brake pedal assembly, including equipment shell 1, equipment shell 1 bottom is equipped with installation through -hole 3, equipment shell 1 is installed with brake cylinder body 2 in, brake cylinder body 2 is connected with pedal assembly 4, and the limiting mechanism 5 is equipped in telescopic arm 403, through the cooperation of pedal assembly 4 and limiting mechanism 5, the height and angle of pedal body 404 can be adjusted, and the comfort of use is promoted.

[0023] As Figure 3 and Figure 4 The utility model discloses a technical scheme of brake pedal assembly, including equipment shell 1, equipment shell 1 bottom is equipped with installation through -hole 3, equipment shell 1 is installed with brake cylinder body 2 in, brake cylinder body 2 is connected with pedal assembly 4, and the limiting mechanism 5 is equipped in telescopic arm 403, through the cooperation of pedal assembly 4 and limiting mechanism 5, the height and angle of pedal body 404 can be adjusted, and the comfort of use is promoted.

[0024] Specifically, when the knob 504 is rotated, it will drive the worm 506 to start rotating. The rotation of the worm 506 will be further transmitted to the worm gear 507, so that it also starts to rotate. The rotating action of the worm gear 507 will directly affect the winding wheels 509 at both ends of the drive shaft 503, so that they follow the rotation. With the rotation of the winding wheels 509, the steel wire rope 508 will be gradually wound up. The winding action of the steel wire rope 508 will trigger a series of chain reactions, which will make the large pin 501 and the small pin 505 respectively separate from the first adjusting hole 402 and the second adjusting hole 407. When the large pin 501 separates from the first adjusting hole 402, the telescopic arm 403 can freely slide in the pressing arm 401, so that the height of the pedal body 404 is adjusted. At the same time, after the small pin 505 separates from the second adjusting hole 407, the pedal body 404 can be rotated to adjust its angle to adapt to different use requirements. The whole process is completed through a series of accurate mechanical transmission and adjustment mechanism, which ensures the accuracy and reliability of the adjustment process.

[0025] As shown in Figure 3 and Figure 5 , the limiting mechanism 5 includes a drive shaft 503 rotatably installed in the telescopic arm 403, a worm gear 507 fixedly installed on the drive shaft 503, a worm 506 rotatably installed below the worm gear 507, and the worm gear 507 and the worm 506 are engaged together, a knob 504 fixedly installed at one end of the worm 506, winding wheels 509 fixedly installed at both ends of the drive shaft 503, a large pin 501 slidably installed at the upper end edge of the telescopic arm 403, a small pin 505 slidably installed at the lower end edge of the telescopic arm 403, a reset spring 502 sleeved on the large pin 501 and the small pin 505, a steel wire rope 508 between the large pin 501 and the winding wheel 509 at the upper end of the drive shaft 503, and a steel wire rope 508 between the small pin 505 and the winding wheel 509 at the lower end of the drive shaft 503, a retainer is provided in the telescopic arm 403, and the drive shaft 503 is rotatably installed in the telescopic arm 403 through the retainer.

[0026] Specifically, the reverse rotation of the knob 504 will make the winding wheels 509 also start to rotate in reverse. The steel wire rope 508 on the winding wheels 509 is gradually released under the action of reverse rotation, and this release process allows the steel wire rope 508 to be released from the tense state. Once the steel wire rope 508 is released, the reset spring 502 begins to play a role, which will exert force to push the large pin 501 and the small pin 505. The two pins are respectively accurately embedded into the first adjusting hole 402 and the second adjusting hole 407, which ensures that the connection between the telescopic arm 403 and the pedal body 404 remains stable and fixed.

[0027] Working principle: when using, the knob 504 can be rotated, after the knob 504 is rotated, the worm 506 is rotated, after the worm 506 is rotated, the worm gear 507 is rotated, after the worm gear 507 is rotated, the winding wheels 509 at both ends of the drive shaft 503 are rotated, after the winding wheels 509 at both ends of the drive shaft 503 are rotated, the steel wire rope 508 is wound, after the steel wire rope 508 is wound, the large pin 501 and the small pin 505 are separated from the first adjusting hole 402 and the second adjusting hole 407 respectively, after the large pin 501 is separated from the first adjusting hole 402, the telescopic arm 403 can slide freely in the pressing arm 401, so that the height of the pedal body 404 is adjusted, after the small pin 505 is separated from the second adjusting hole 407, the pedal body 404 can be rotated, so that the angle of the pedal body 404 is adjusted, facilitating the user to use. After the adjustment is completed, the knob 504 can be rotated in reverse, after the knob 504 is rotated in reverse, the winding wheels 509 at both ends of the drive shaft 503 are rotated in reverse, so that the steel wire rope 508 on the winding wheels 509 is released, after the steel wire rope 508 is released, the reset spring 502 pushes the large pin 501 and the small pin 505 to be embedded in the first adjusting hole 402 and the second adjusting hole 407 respectively, so that the telescopic arm 403 and the pedal body 404 are kept fixed.
