DETAILED DESCRIPTION

[0028] The following will be combined with the accompanying drawings to clearly and completely describe the technical solutions in the embodiment of the utility model 1. Obviously, the described embodiment is only a part of the embodiment of the utility model 1, not all of the embodiments. Based on the embodiment of the utility model 1, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model 1.

[0029] It should be noted that if the embodiment of the utility model 1 involves directional indications (such as up, down, left, right, front, back, top, bottom, inside, outside, vertical, horizontal, longitudinal, counterclockwise, clockwise, circumferential, radial, axial...), then the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0030] In addition, if there are descriptions involving "first" or "second" etc. in the embodiment of the utility model 1, the descriptions of "first" or "second" etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the utility model 1.

[0031] The utility model 1 provides a brake structure for a baby carriage.

[0032] In the present utility model 1 embodiment, as Figures 1 to 5As shown in the figure, the utility model 1 includes a wheel set 3 and a brake pedal 2. The wheel set 3 is provided with wheels. The brake pedal 2 includes a pedal body 21 for foot stepping, and pivot parts 22 arranged on both sides of the pedal body 21 and formed with rotating inclined surfaces 221. Secondly, it further includes a brake rod push rod 7. When the brake pedal 2 rotates, the rotating inclined surface 222 drives the brake rod push rod 7 to move towards the side close to the wheel. Correspondingly, it also includes a brake rod 6, and the brake rod push rod 7 is cooperatively connected with the brake rod 6. Additionally, it further includes a brake tooth 5. The brake tooth 5 moves synchronously with the wheel set 3. The brake tooth 5 is provided with at least one slot 51. The brake rod 6 can move between inserting into the slot 51 and withdrawing from the slot 51. When the brake rod push rod 7 moves towards the side close to the wheel, it can push the side of the brake rod 6 close to the wheel to move to the brake tooth 5 for braking. Finally, it also includes a rear wheel seat 4. The rear wheel set 4 is arranged on one side of the wheel set 3, and the side far from the wheel is connected to the brake pedal 2.

[0033] In this embodiment, the pedal body 21 includes an inner stepping part 211 and an outer stepping part 212. The inner stepping part 211 is recessed into the outer stepping part 212. This kind of recessed structure makes the inner stepping part 211 and the outer stepping part 212 show a trend of height difference in structure, which is convenient for the user to step on. Specifically, the user only needs to step on the inner stepping part 211 and apply force, which is more labor-saving compared with the straight plate structure of the prior art.

[0034] More specifically, the surface of the inner stepping part 211 is provided with friction lines 213 for anti-slip. The friction lines 213 belong to the prior art and will not be elaborated here. It is worth noting that the anti-slip effect will be better when the friction lines 213 are inclined relative to the surface of the brake pedal 2.

[0035] Furthermore, the surface of the outer stepping part 212 is provided with friction lines 213 for anti-slip. In a preferred embodiment, setting friction lines 213 on both the inner stepping part 211 and the outer stepping part 212 can better achieve the anti-slip purpose.

[0036] In some other embodiments, to further facilitate the user's stepping, the inner stepping part 211 is provided with holes 214 penetrating the plate body. When stepping is required, the user can insert the foot into the holes 214 to achieve a more labor-saving stepping action.

[0037] In this embodiment, the pivot part 22 further includes a cover lock 222 for fixing the brake pedal 2. The cover lock 222 is screwed on the pivot part 22 and fixed by screws.

[0038] In this embodiment, an elastic member (not shown) is provided between the brake lever 6 and the brake lever push rod 7. During the downward rotation of the pivoting portion 22, the rotating inclined surface 221 formed on the pivoting portion 22 drives the brake lever push rod 7 to perform a lateral displacement. At this time, after the brake lever push rod 7 moves laterally, the internal elastic member undergoes elastic deformation accordingly. The elastic member pushes the brake lever 6 to move onto the slot 51 of the brake tooth 5. As a preferred embodiment, the elastic member specifically uses a spring. In some other embodiments, the elastic member can be replaced with other elastic components such as rubber or sponge. The replacement of the elastic member belongs to the prior art part and will not be elaborated here.

[0039] In this embodiment, the brake lever push rod 7 is provided with a positioning groove 8, and a positioning member 9 passes through the positioning groove 8 and penetrates through the brake lever 6. The positioning member 9 preferably uses a pin, and the pin penetrates through the brake lever 6. Specifically, the positioning member 9 moves within the range of the positioning groove 8 to limit the movement of the brake lever 6 and prevent the brake lever 6 and the brake lever push rod 7 from rotating. In some other embodiments, the pin can be replaced with components such as screws or hooks. In fact, the premise for replacing different embodiments of the positioning member 9 is only that it can penetrate the brake lever 6 and the positioning groove 8, and only this condition needs to be followed during the replacement of the embodiments.

[0040] In this embodiment, the rotating inclined surface 221 is preferably formed as a conical groove, and one end of the brake lever push rod 7 close to the rotating inclined surface 221 is formed as a mating cone and abuts against it. The function of the rotating inclined surface 221 is to dock with the external brake lever push rod 7. Since during the specific braking process, it is achieved by stepping on the brake pedal 2 downward to drive the operation of other brake parts, the profile of the rotating inclined surface 221 of the pivoting portion 22 being formed as a cone is beneficial for the brake lever push rod 7 to perform better lateral displacement during rotation.

[0041] In this embodiment, each slot 51 formed on the brake tooth 5 faces the center of the brake tooth 5. The advantage of this structure is that it can guide the brake lever 6 to insert into the slot 51, making the braking process smoother.

[0042] The following content is the working principle description of the present utility model 1:

[0043] During use, when the brake pedal 2 is depressed, the brake pedal 2 rotates downward. The rotating inclined surface 221 formed on the pivoting portion 22 drives the brake lever push rod 7 to perform a lateral displacement. After the elastic member is compressed, it releases elastic potential energy. The elastic member pushes the brake lever 6 to move to the brake tooth 5 for braking. The key point of the present utility model 1 is that the brake pedal 2 serves as the starting part for the operation of the entire braking process. Specifically, the rotating inclined surface 221 drives the brake lever push rod 7 and drives the brake lever 6 to extend into the slot 51 of the brake tooth 5 for braking.

[0044] The above are only the preferred embodiments of the present utility model 1, and do not thus limit the patent scope of the present utility model 1. Any equivalent structural transformation made under the inventive concept of the present utility model 1 by using the content of the specification and drawings of the present utility model 1, or any direct / indirect application in other related technical fields shall be included within the patent protection scope of the present utility model 1.
