Referring to the drawings, the rear wheel assembly 200 includes a wheel housing 1 for fixed connection with the vehicle frame 100, and a wheel 4 rotatably mounted on the wheel housing 1 through an axle 7. The brake mechanism comprises a brake disc 3 fixedly arranged on a wheel 4 and a brake assembly 2 arranged on a wheel seat 1, wherein the brake assembly 2 at least comprises a brake pad 21, the brake pad 21 is an annular member with two end parts, and the brake pad 21 is annularly arranged on the circumferential outer side of the brake disc 3. A limiting structure for limiting the brake pad 21 in the circumferential direction is further arranged between the brake pad 21 and the wheel seat 1. When the brake mechanism is in a brake-releasing state, the brake pad 21 is separated from the brake disc 3, and the wheels 4 can rotate freely, when the brake mechanism is in a brake-releasing state, the brake pad 21 is deformed, and the brake pad 21 is tightly held on the outer peripheral part of the brake disc 3, so that quick braking is realized, and the baby carrier is stopped quickly to achieve the purpose of parking.
Specifically, referring to fig. 3, 10 and 13, the brake pad 21 is a self-elastic integral member, preferably made of spring steel. When the brake mechanism is switched from the brake release state to the brake state, the two ends of the brake pad 21 are close to each other, so that the brake pad 21 is deformed, and the brake pad 21 is tightly held on the brake disc 3.
The brake assembly 2 further comprises a friction plate 22 fixedly arranged on the inner side surface of the brake pad 21, wherein the friction plate 22 is preferably made of rubber material, and when the brake mechanism brakes, the friction plate 22 is contacted on the outer peripheral surface of the brake disc 3 to realize braking, and the friction plate 22 can be replaced after being worn.
In this embodiment, as shown in fig. 3, the brake pad 21 includes a split ring portion 21a which is disposed around the outer side of the brake disc 3, and connection end portions 21b which are respectively bent and extended outward from both ends of the split ring portion 21a, the split ring portion 21a and the two connection end portions 21b are integrally formed as a single piece made of the same material (here, spring steel), and the friction plate 22 is detachably mounted on the inner side surface of the split ring portion 21 a. The opening angle of the split ring portion 21a is preferably not more than 150 °. When the two connection end portions 21b are driven relatively close, the opening of the split ring portion 21a is gradually reduced, and the brake pads 21 are deformed so as to be held tightly on the brake disc 3 to achieve braking.
The brake mechanism further comprises a brake actuating member for actuating the two connecting ends 21b of the brake pads 21 towards each other. Here, referring to fig. 8 to 13, the brake driving member includes a brake cable 5 disposed between two connection ends 21b, and a brake lever 6 for tensioning the brake cable 5 is further disposed on the frame 100, and the brake cable 5 can be tensioned by operating the brake lever 6 to drive the two connection ends 21b to be relatively close to each other, thereby realizing braking.
Referring to the drawings, the limit structure comprises a plurality of limit parts arranged on the brake pad 21 at intervals along the circumferential direction, and a plurality of matching parts arranged on the wheel seat 1 and matched with the limit parts, wherein the limit parts are in one-to-one correspondence with the matching parts, and the limit parts and the matching parts are mutually matched to limit the displacement of the brake pad 21 along the radial direction of the brake disc 3. In this embodiment, the limiting portion is a limiting pin 23 fixedly disposed on the brake pad 21, the limiting pin 23 is specifically disposed on the split ring portion 21a of the brake pad 21 and extends along the radial direction of the split ring portion 21a, the mating portion is a limiting groove 11 formed on the wheel seat 1, and the limiting pin 23 can slide relatively along the axial direction and/or rotate relatively and pass through the limiting groove 11. Here, the stopper pins 23 have three groups spaced apart along the length extension direction of the brake pad 21, and correspondingly, the stopper grooves 11 on the wheel seat 1 are also provided with three groups. The limit groove 11 and the limit pin 23 of the limit structure are matched no matter the brake mechanism is in a brake state or a brake release state. In this embodiment, the wheel seat 1 has a disk-shaped base and an annular baffle plate provided on the base and extending to one side in the circumferential direction, and all the limit grooves 11 are provided on the annular baffle plate. An accommodating space is formed between the base and the annular baffle plate, and the brake disc 3 is accommodated in the accommodating space.
Referring to fig. 10, the brake mechanism is in a brake release state, a space is provided between the inner side surface of the friction plate 22 and the brake disc 3 in the brake assembly 2, and the wheel 4 and the brake disc 3 can rotate relative to the frame 100, i.e. the baby carrier can normally run. When the brake lever 6 is operated to tension the brake cable 5, as shown in fig. 13, the two connection ends 21b of the brake pad 21 in the brake assembly 2 are relatively close, so that the opening of the split ring portion 21a is gradually reduced, the diameter of the split ring portion 21a is reduced, the friction plate 22 on the inner side of the split ring portion is gradually contacted to the outer peripheral portion of the brake disc 3, and finally the brake assembly 2 hugs the brake disc 3 in the circumferential direction, so that the brake disc 3 and the wheels 4 cannot rotate continuously, the baby carrier is stopped rapidly, and the purpose of parking is achieved. When the brake is not needed to be continued, an operator releases the brake handle 6, the brake cable 5 is released, the brake pad 21 is restored to the original state under the action of the elastic force of the brake pad 21 and the limiting action of the limiting pin 23 and the limiting groove 11, and the brake assembly 2 is separated from the brake disc 3, so that the brake release is realized.
In conclusion, the brake mechanism provided by the invention has the advantages of simple structure and convenience in operation, and can rapidly realize braking to achieve the purpose of parking.
