The main function of the brake bracket is to provide a stable mounting platform for the brake, ensuring that the brake can accurately act on the brake drum or brake disc to achieve the purpose of deceleration or stopping. It is also responsible for transmitting the braking force to the vehicle's wheel axle to generate sufficient friction to slow down or stop the vehicle. Existing braking devices are mostly one-way braking devices. One-way brakes have poor performance stability during braking, resulting in uneven braking force during the braking process.

[0003] Therefore, the utility model proposes a bidirectional brake bracket. Utility Model Content

[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example 1

[0025] See Figures 1 to 5 As shown, the bidirectional brake bracket provided by the utility model includes a main connecting shaft 1, a movable hole is opened inside the main connecting shaft 1, and two groups of connecting push blocks 5 are slidably sleeved inside the movable hole, and transmission push blocks 4 are set on the opposite sides of the two groups of connecting push blocks 5. The bottom ends of the connecting push blocks 5 are fixedly connected to transmission rods 7, and the opposite sides of the two groups of transmission rods 7 are fixedly connected to springs 8. The outer sides of the two groups of transmission rods 7 are fixedly connected to transmission devices, and the two ends of the transmission devices are respectively fixedly connected to brake mechanisms, and the sides of the brake mechanisms are fixedly connected to side fixing plates 2, and the opposite sides of the two groups of side fixing plates 2 are fixedly connected to the main connecting shaft 1;

[0026] The two sets of brake mechanisms are internally movably sleeved with a brake disc 6 , and the two sets of brake mechanisms are respectively arranged on both sides of the upper end of the brake disc 6 .

[0027] The transmission device includes a rack 9, the inner side of the rack 9 is fixedly connected to the transmission rod 7, the bottom end of the rack 9 is meshed with a gear shaft 10, both ends of the gear shaft 10 are fixedly connected to a hinge block 12, the interior of the hinge block 12 is hinged with one end of a rotating shaft 13, the other end of the rotating shaft 13 is movably sleeved with the inside of a connecting rotary block 14, the bottom end of the connecting rotary block 14 is fixedly connected to a transmission shaft 2 16, the outer wall of the transmission shaft 2 16 is movably sleeved with a limit block 15, and the side of the limit block 15 is fixedly connected to the side fixing plate 2.

[0028] When braking is needed, the transmission push block 4 is pushed downward by an external mechanism. At this time, the beveled surface at the lower end of the transmission push block 4 pushes the connecting push block 5 to slide to both sides, thereby driving the two sets of transmission rods 7 to slide to both sides, so that the rack 9 is engaged with the gear shaft 10, and the gear shaft 10 is rotated. The rotating gear shaft 10 causes the hinge blocks 12 on both sides to synchronously drive the rotating shaft 13 and the connecting rotating block 14 to rotate with the transmission shaft 2 16 as the center, and further drives the transmission shaft 2 16 to rotate inside the limit block 15, so that the braking mechanism is activated and the surface of the brake disc 6 is clamped, thereby producing a braking effect. By activating the four sets of braking mechanisms at the same time, it is avoided that the vehicle deviates due to uneven braking force.

[0029] Example 2

[0030] Based on Example 1, please refer to Figures 1 to 5 As shown, the braking mechanism includes an outer frame 3, the side of the outer frame 3 is fixedly connected to the side fixing plate 2, both ends of the outer frame 3 are fixedly connected to the connecting rod 1 20, the inner wall of the connecting rod 1 20 is movably connected to two groups of connecting rods 21, the outer walls of the connecting rods 21 are fixedly connected to movable clamps 11, and extrusion blocks 19 are provided on the opposite sides of the two groups of movable clamps 11, and the interior of the extrusion block 19 is fixedly connected to the transmission shaft 2 16.

[0031] One end of a second spring 18 is fixedly connected to one side of the movable clip 11 close to the outer frame 3 , and the other end of the second spring 18 is fixedly connected to the outer frame 3 .

[0032] The extrusion block 19 is an irregular rectangle and is disposed inside the outer frame 3 .

[0033] Brake pads 17 are fixedly connected to opposite sides of the two groups of movable clips 11 , and opposite sides of the two groups of brake pads 17 are in contact with the outer wall of the brake disc 6 .

[0034] When braking is required, the rotation of the second transmission shaft 16 drives the extrusion block 19 to rotate inside the two sets of movable clips 11, so that the two sets of movable clips 11 rotate synchronously with the connecting rod 21 as the center. When the extrusion block 19 is in an inclined state, the two sets of brake pads 17 at the bottom end fit the surface of the brake disc 6. On the contrary, when the extrusion block 19 is in a parallel or vertical state, it is affected by the elastic potential energy of the second spring 18, and the two sets of movable clips 11 are narrow at the upper end and wide at the lower end to eliminate contact with the surface of the brake disc 6. This simultaneous braking on both sides can make the braking force uniform during braking.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
