Braking device of vehicle

Abstract

The invention relates to a braking device of a vehicle. The vehicle comprises a vehicle frame and two wheels, the braking device comprises a control unit and at least one braking unit, wherein the control unit comprises a control piece and a braking wire, the braking unit comprises a pivot seat, a braking disc, a braking piece and an elastic piece, wherein the pivot seat is fixedly arranged on the vehicle frame, the braking disc is fixedly arranged on one of the wheels and is provided with at least one embedding part, the braking piece passes through the pivot seat and is provided with a clamping piece which is embedded with the embedding part, and the elastic piece is used for keeping the braking piece to move towards the braking disc. When the control piece is positioned at a braking position, the clamping part is embedded with the embedding part, and therefore, the wheels are unable to rotate; when the control piece is positioned at a running position, the clamping part is separated from the embedding part, the wheels can rotate, and thus, the braking device not only has easy operation, but also has better braking effect.

Description

technical field [0001] The invention relates to a brake device, in particular to a brake device for a vehicle that is towed or pushed. Background technique [0002] Due to the prevalence of bicycle leisure activities, leisure-related peripheral equipment is becoming more and more diverse, and trailers are one of them. [0003] see Figure 1 ~ Figure 3 Shown is a brake device 2 of an existing trailer 1, the trailer 1 is suitable for carrying babies or transporting items, and includes a vehicle frame 11, and two wheels 12 respectively arranged on the left and right sides of the vehicle frame 11, The vehicle frame 11 includes a bottom frame 111, a ceiling frame 112 connected to the bottom frame 111, two side push rods 113 respectively connected to both sides of the ceiling frame 112, and a side push rod 113 connected to the bottom frame 113. Crossbar 114. The brake unit 2 includes two calipers 21 arranged on both sides of the bottom frame 111 and respectively used to clamp th...

Problems solved by technology

[0005] Although the brake device 2 can make the trailer 1 have the function of braking, when the calipers 21 respectively clamp the wheel frames, a certain clamping force must be reached to keep the wheels 12 stationary, that is, the brake The handle 22 must move a considerable distance to tighten the brake line 23 so that the caliper 21 can produce sufficient clamping force, so that when the user's strength is small or can only be operated by one hand, Difficult to operate, and unable to make the caliper 21 produce enough clamping force to reduce the braking effect and other problems, and when the trailer 1 is going to brake when the trailer 1 is traveling on a bumpy road, the user is often unable to hold the trailer 1 stably due to vibration. The phenomenon that the brake handle 22 brakes will also greatly reduce the braking effect

[0006] This shows that the above-mentioned existing vehicle braking device obviously still has inconvenience and defects in structure and use, and needs to be further improved urgently.

In order to solve the above-mentioned problems, the relevant manufacturers have tried their best to find a solution, but for a long time no suitable design has been developed, and the general product has no suitable structure to solve the above-mentioned problems. This is obviously the relevant industry. Urgent problem
