[0025] The utility model provides a double-sided brake structure.

[0026] In the embodiment of the utility model, Figures 1 to 2As shown in the figure, the bilateral braking structure includes a brake pedal 1 and a brake assembly 2. The brake pedal 1 is assembled on the rear foot tube 9 and is rotatably arranged on the rear foot tube 9. The brake assembly 2 includes a left rear wheel brake assembly 21 and a right rear wheel brake assembly 22. The left rear wheel brake assembly 21 is used to brake the left rear wheel, and the right rear wheel brake assembly 22 is used to brake the right rear wheel. In addition, a linkage 3 is included. The brake pedal 1 is connected to the left rear wheel brake assembly 21 and the right rear wheel brake assembly 22 respectively through the linkage 3, so that stepping on the brake pedal 1 once can control the braking of the left rear wheel and the right rear wheel simultaneously.

[0027] In this embodiment, the brake pedal 1 includes a brake upper plate 11 and a brake lower plate 12. The split setting of the brake pedal 1 is beneficial to the internal assembly. As a preferred embodiment that needs to be further explained, a rotating part 13 is provided in the internal assembly structure of the brake upper plate 11 and the brake lower plate 12. The rotating part 13 is arranged through the sides of the brake upper plate 11 and the brake lower plate 12. Through the rotating part 13, the brake pedal 1 performs better rotational movement. In some other embodiments, the brake pedal 1 does not have to be set with a split structure for the rotating part 13, but the assembly is more complex than the preferred embodiment and will not be elaborated.

[0028] Preferably, the brake upper plate 11 is provided with a pattern 14 for increasing friction and anti-slip during stepping. This is part of the prior art and will not be elaborated. In a preferred embodiment, the pattern 14 is set at a lower position on the surface of the brake upper plate 11.

[0029] In this embodiment, a rear foot tube 9 that penetrates and connects to the brake pedal 1 is further included. The rear foot tube 9 is the foot tube part of the frame. The present utility model is docked with the rear foot tube 9 to achieve connection with an external baby stroller.

[0030] In this embodiment, the linkage 3 is a brake cable or a connecting rod, or other rod-like structures with a connecting nature. In a preferred embodiment, taking the brake cable as an example, both ends of the aforementioned rotating part 13 are rotatably connected to the brake cable that drives the brake pin 5 to slide. Both the left rear wheel brake assembly 21 and the right rear wheel brake assembly 22 are provided with brake pins 5. The brake pins 5 are connected to the ends of the brake cable. The brake pin 5 includes a braking end 51 that cooperates with the brake cable and a pin end 52 for triggering or stopping the trigger of the brake.

[0031] In this embodiment, it further includes a tire set 8 with a brake tooth 81 attached. During braking, the pin end 52 of the brake pin 5 extends into the brake tooth 81 on the tire set 8 for abutting connection. Preferably, an elastic member 53 is cooperatively provided on the braking end 51 of the brake pin 5 to enable the brake pin 5 to slide more significantly during braking, facilitating the insertion of the pin end 52 into the brake tooth 81. The elastic member 53 preferably uses a spring, and the spring is specifically wound around the brake pin 5. In some other embodiments, the spring can be replaced with tools commonly used in the prior art that can release elastic potential energy, such as rubber, sponge, and torsion springs. For details, refer to the prior art and will not be elaborated here.

[0032] It should be noted that in the prior art, the brake tooth 81 is usually connected to the tire part as a separate component. As a preferred embodiment of the present invention, the brake tooth 81 is integrally installed with the tire set 8, which is beneficial to reducing the assembly difficulty of the present invention, and at the same time, the linkage relationship during braking is simpler.

[0033] Specifically, the tire set 8 is also cooperatively installed with a shock-absorbing group 83 for reducing vibration during driving. The shock-absorbing group 83 is specifically installed on the tire seat 82. The two sides of the tire seat 82 are fixed by a tire seat cover 84 and a tire seat inner cover 85. In a preferred embodiment, the shock-absorbing group 83 is provided on the tire seat 82 to reduce vibration during driving. Specifically, vibration is absorbed through the elastic structure formed by the shock-absorbing group 83. This is prior art and will not be elaborated.

[0034] In the foregoing embodiment, by stepping on the brake pedal 1, the stroke of the foregoing linkage 3 becomes longer. At this time, the brake pin 5 slides through the release of the elastic potential energy of the elastic member 53 and can slide more smoothly into the brake tooth 81 of the tire set 8, thereby achieving braking.

[0035] In this embodiment, fixing members 6 are provided on both sides of the brake pedal 1 to prevent the brake pedal 1 from moving around. The fixing members 6 fix the brake pedal 1 by abutting against it. As a preferred embodiment, the fixing member 6 includes a first fixing member 61 and a second fixing member 62. In this split-type setting, the whole formed after key connection between the first fixing member 61 and the second fixing member 62 is connected to the left or right side of the brake pedal 1. The two fixing members 6 abut against the brake pedal 1 from both sides to fix it. In some other embodiments, the fixing member 6 can abut against the brake pedal 1 through an integral setting. For example, after the fixing member 6 is provided on both sides of the brake pedal 1, a connecting column is provided between the two fixing members 6. After the connecting column connects the two fixing members, the brake pedal 1 is abutted by the supporting force of the connecting column to keep it stable. It can be understood that in the foregoing preferred embodiment, the fixing member 6 is fixed by split-type key connection to maintain good stability.

[0036] Specifically, the present utility model further includes a positioning member 4 for restricting the rotational movement of the brake pedal 1, and the positioning member 4 is cooperatively connected with the brake pedal 1.

[0037] Further, a positioning groove (not shown) is formed inside the fixing member 6, and the positioning member 4 for locking the rotational direction of the brake pedal 1 is installed on the positioning groove. When the brake pedal 1 is stepped on, the brake pedal 1 rotates to drive the positioning member 4, causing the positioning member 4 to snap into the positioning groove, thereby fixing the rotational direction of the brake pedal 1. Preferably, one end of the positioning member 4 is set to a tip type, which is beneficial for connection setting and positioning functions.

[0038] Furthermore, a reset member 7 for resetting the positioning member 4 after braking is provided at one end of the positioning member 4 facing the brake pedal 1. The reset member 7 preferably uses a spring, and the spring is fixedly abutted against one end of the positioning member 4. In some other embodiments, the spring can be replaced with tools commonly used in the prior art such as rubber, sponge, and torsion springs that have a rebound function. For details, refer to the prior art and will not be elaborated here.

[0039] The following content is an explanation of the working principle of the present utility model:

[0040] When braking is required, step on the brake pedal 1 downward. The brake pedal 1 is stressed and makes a rotational movement. When the brake pedal 1 rotates, it drives the positioning member 4, causing the positioning member 4 to snap into the positioning groove formed in the fixing member 6, thereby fixing the movement of the rotational direction of the brake pedal 1. At this time, the stroke of the linkage member 3 becomes longer, causing the brake bolt 5 to slide under the action of the elastic member 53 and slide into the tooth groove of the rear wheel brake tooth 81, thereby achieving braking. Finally, reverse operation can unlock the brake. It is worth mentioning that the most prominent feature of the present utility model is that it can perform simple bilateral braking.

[0041] The above are only the preferred embodiments of the present utility model, and do not limit the patent scope of the present utility model accordingly. Any equivalent structural transformation made under the inventive concept of the present utility model by using the specification and drawings of the present utility model, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present utility model.
