For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0047] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0048] like Figures 1-4 As shown, the braking system of this embodiment can be applied to the rear wheel assembly of a stroller. Specifically, the cyclic braking system of this embodiment mainly includes: a mounting body 1, a brake pin module 2, and a drive module 3. The mounting body 1 mainly includes: two mounting seats 11 and a connecting shaft 10. The brake pin module 2 mainly includes: a push rod 20, a brake pin 21, a third spring 22, and a fourth spring 23. The drive module 3 mainly includes: a brake pedal 30, a brake rotating seat 31, and a brake caliper 32.

[0049] Mounting body 1 serves as the support structure for the entire braking system, providing mounting positions for other components and ensuring overall strength. Mounting body 1 mainly includes two spaced mounting seats 11 and a connecting shaft 10 connecting the two mounting seats 11. The mounting seats 11 can be made of plastic, and the connecting shaft 10 can be made of metal.

[0050] like Figures 2-7 As shown, the brake pin module 2 is retractably mounted on the mounting body 1. The brake pin module 2 includes a push rod 20, a brake pin 21, a third spring 22, and a fourth spring 23. One end of the push rod 20 movably abuts against the brake rotating seat 31. The brake pin 21 is retractably mounted on the other end of the push rod 20. The third spring 22 is tensioned between the brake pin 21 and the push rod 20. The fourth spring 23 is tensioned between the push rod 20 and the mounting body 1. When the brake rotating seat 31 drives the brake pin module 2 to extend and perform a braking action, the fourth spring 23 is compressed. The elastic force of the fourth spring 23 causes the push rod 20 to maintain a tendency to move towards the side closer to the brake rotating seat 31.

[0051] In actual use, the pushing rod 20 is in contact with the second pushing part 312 of the brake rotating seat 31 in the non-braking state. When the brake action is performed, the second pushing part 312 of the brake rotating seat 31 is pressed against the pushing rod 20 to make the pushing rod 20 extend outward, and the brake pin 21 also extends outward under the action of the pushing rod 20 and the third spring 22. When the brake rotating seat 31 rotates to push the pushing rod 20 through the first pushing part 311, the extension of the pushing rod 20 is completed. When the brake pin 21 is aligned with the lock hole on the wheel, the brake pin 21 is locked into the lock hole of the wheel to complete the braking. If the brake pin 21 is not aligned with the lock hole on the wheel, the brake pin 21 is still in the retracted state, and the third spring 22 is also in the compressed state. As long as the brake pin 21 is aligned with the lock hole on the wheel, the third spring 22 will drive the brake pin 21 to lock into the lock hole to complete the braking. In this embodiment, the brake pin module 2 is equivalent to a floating pin, which ensures that the brake pin module 2 is not easy to be stuck during the braking process.

[0052] As shown in Figures 2-8 the driving module 3 is movably arranged on the mounting body 1. The driving module 3 includes a brake pedal 30, a brake rotating seat 31, and a brake clamping seat 32. The brake rotating seat 31 is rotatably arranged on the mounting body 1, specifically rotatably sleeved on the connecting shaft 10 and pivotable relative to the connecting shaft 10. A plurality of first pushing parts 311 and a plurality of second pushing parts 312 are arranged on the brake rotating seat 31. The brake rotating seat 31 can abut against the brake pin module 2 through the first pushing parts 311 to make the brake pin module 2 extend outward to perform the braking action. The brake rotating seat 31 can abut against the brake pin module 2 through the second pushing parts 312 to make the brake pin module 2 retract to perform the unbraking action. The brake pedal 30 is movably arranged on the mounting body 1, specifically rotatably arranged between the two mounting seats 11 of the mounting body 1, and the brake pedal 30 is sleeved on the brake rotating seat 31. The brake pedal 30 has a cover plate 301 detachably fixedly connected thereto. The cover plate 301 is arranged to facilitate the assembly of the brake clamping seat 32. The brake clamping seat 32 is rotatably arranged on the brake pedal 30 through a rotating shaft, and a first spring 320 is arranged between the brake pedal 30 and the brake clamping seat 32. The action force of the first spring 320 on the brake clamping seat 32 makes the brake clamping seat 32 abut against the brake rotating seat 31. The brake clamping seat 32 movably abuts against the brake rotating seat 31. When the brake pedal 30 is stepped on, the brake pedal 30 pushes the brake rotating seat 31 through the brake clamping seat 32 to make the brake rotating seat 31 rotate.

[0053] In actual use, stepping on the brake pedal 30 can make the brake rotating seat 31 rotate to change the abutting position of the brake pin module 2 on the brake rotating seat 31, that is, the abutting position of the brake rotating seat 31 and the brake pin module 2 can be the first pushing part 311 or the second pushing part 312, which can be switched cyclically.

[0054] Specifically, the brake rotating seat 31 of the embodiment is provided with four first pushing parts 311 and four second pushing parts 312 on one side, and the four first pushing parts 311 and the four second pushing parts 312 are arranged alternately. That is, one second pushing part 312 is arranged between two adjacent first pushing parts 311, and one first pushing part 311 is arranged between two adjacent second pushing parts 312. When the brake pedal 30 is stepped down, the abutting position of the brake pin module 2 is switched alternately between the first pushing part 311 and the second pushing part 312, that is, the cycle braking and cycle unbraking can be realized.

[0055] In the embodiment, when the brake pedal 30 is stepped down, the brake pedal 30 can drive the brake rotating seat 31 to rotate, and the brake rotating seat 31 abuts against the brake pin module 2 through the first pushing part 311 or the second pushing part 312, so as to realize the brake action of the brake pin module 2 extending outwards or the unbraking action of the brake pin module 2 retracting inwards. The overall structure of the brake system is simple, and the brake pedal 30 is stepped down to realize braking, the brake pedal 30 is stepped down again to realize unbraking, and the brake pedal 30 is stepped down again to realize braking, and so on, so that the cycle braking and cycle unbraking can be realized, and the two actions of braking and unbraking are exactly the same, that is, the consistency of the actions of braking and unbraking is good.

[0056] Further specifically, the second spring 302 is arranged between the brake pedal 30 and the installation main body 1. When the brake pedal 30 is stepped down, the brake pedal 30 compresses the second spring 302. After the brake pedal 30 is released, the second spring 302 drives the brake pedal 30 to reset.

[0057] The brake rotating seat 31 is provided with a plurality of clamping grooves 313 along the circumference thereof, and the brake clamping seat 32 is clamped in the clamping grooves 313 and can be switched in the plurality of clamping grooves 313. Specifically, the sum of the number of the first pushing part 311 and the second pushing part 312 of the embodiment is equal to the number of the clamping grooves 313. Specifically, since the number of the first pushing part 311 and the second pushing part 312 of the embodiment is four, the number of the clamping grooves 313 is eight, and each clamping groove 313 has a corresponding first pushing part 311 or second pushing part 312. In actual use, when the brake pedal 30 is stepped down, the brake clamping seat 32 abuts against the clamping groove 313, so as to drive the brake rotating seat 31 to rotate. After the brake pedal 30 is released, the second spring 302 drives the brake pedal 30 to reset, the brake pedal 30 drives the brake clamping seat 32 to move, the brake clamping seat 32 is clamped into the next clamping groove 313, and the brake rotating seat 31 remains stationary, so as to ensure that the braking and unbraking are reliable. That is, the brake clamping seat 32 can only drive the brake rotating seat 31 to rotate in one direction, and cannot drive the brake rotating seat 31 to rotate in the opposite direction.

[0058] Need to explain, in the brake and brake release process, when the brake pin module 2 switches between the first push part 311 and the second push part 312 once, the brake clamp seat 32 is clamped into the next clamping groove 313. Understandably, when the brake rotating seat 31 rotates 360 degrees, four times of braking and four times of brake release are performed, and the brake clamp seat 32 switches in eight clamping grooves 313 for one cycle.

[0059] Among them, each clamping groove 313 in the eight clamping grooves 313 has an adjacent push wall 313A and an inclined wall 313B. When the brake clamp seat 32 pushes the brake rotating seat 31 to rotate, the brake clamp seat 32 abuts against the push wall 313A, and when the brake pedal 30 is released, the brake clamp seat 32 is clamped into the next clamping groove 313 along the inclined wall 313B.

[0060] In this embodiment, the brake rotating seat 31 is provided with clamping grooves 313 equal to the sum of the number of the first push part 311 and the second push part 312. The cooperation of the clamping groove 313 and the brake clamp seat 32 makes the brake pedal 30 not only drive the brake rotating seat 31 to rotate through the brake clamp seat 32, but also makes the brake clamp seat 32 not drive the brake rotating seat 31 to rotate after the braking or brake release action is completed, ensuring reliable braking and brake release and good structural stability.

[0061] The working principle of the brake system of the embodiment is as follows: in the unbraked state, the brake pin module 2 is against the second pushing part 312. When braking is needed, the brake pedal 30 is stepped on, the brake pedal 30 is rotated to drive the brake clamp 32 to rotate together, and the second spring 302 is compressed. Because the first spring 320 makes the brake clamp 32 tightly against the brake rotating seat 31, the brake clamp 32 pushes the pushing wall 313A on the brake rotating seat 31, so that the brake rotating seat 31 is rotated. The rotation of the brake rotating seat 31 makes the pushing position of the brake pin module 2 change from the second pushing part 312 to the first pushing part 311, the brake pin module 2 is extended, and the braking action is performed. In this process, the brake rotating seat 31 is rotated by 45 degrees. After the brake pedal 30 is released, the second spring 302 drives the brake pedal 30 to rotate reversely to restore the initial position, and the brake pedal 30 drives the brake clamp 32 to reset, the brake clamp 32 is clamped into the next clamping groove 313 along the inclined wall 313B of the clamping groove 313 on the brake rotating seat 31, and the brake clamp 32 cannot drive the brake rotating seat 31 to reset, that is, the brake rotating seat 31 is not moved, so that the brake system remains in the braking state. When the brake needs to be released, the brake pedal 30 is stepped down, the brake pedal 30 is rotated, and the brake clamp 32 is rotated, the brake clamp 32 drives the brake rotating seat 31 to rotate by 45 degrees, and then the pushing position of the brake pin module 2 changes from the first pushing part 311 to the second pushing part 312, the brake pin module 2 is retracted, and the brake releasing action is performed. After the brake pedal 30 is released, the second spring 302 drives the brake pedal 30 to rotate reversely to restore the initial position, and the brake pedal 30 drives the brake clamp 32 to reset, the brake clamp 32 is clamped into the next clamping groove 313 along the inclined wall 313B of the clamping groove 313 on the brake rotating seat, and the brake clamp 32 cannot drive the brake rotating seat 31 to reset, that is, the brake rotating seat 31 is not moved, so that the brake system remains in the brake releasing state, so that the brake and the brake releasing can be circularly performed.
