Description

Technical Field

[0001] The utility model relates to the technical field of baby carriage component technology, in particular to a brake positioning device for improving safety performance. Background Art

[0002] The brake positioning device is one of the important guarantees of automobile safety and plays an indispensable role in ensuring automobile safety. Often a safe brake positioning device can ensure the safety of the car and the driver in an emergency, so a simple and safe brake positioning device is needed.

[0003] According to the Chinese patent with the announcement number: CN219687416U, a baby stroller brake positioning device includes a protective cover tube and two groups of baby stroller wheels, a brake assembly, and a pedal assembly arranged on the protective cover tube. The baby stroller wheels are rotatably connected to both sides of the protective cover tube, the brake assembly is arranged on the inner side of the rear wheel of the baby stroller, the foot brake assembly is arranged in the middle position of the protective cover tube, and vertical brake pads are arranged on the outer side of the baby stroller wheels.

[0004] In the above scheme, the wheels of the baby carriage are rotatably connected to both sides of the protective cover tube, and the brake assembly is arranged on the inner side of the wheels of the baby carriage. Through the vertical brake pads and the vertical docking holes, this new braking method has better braking stability.

[0005] The above scheme still has the following disadvantages: the new type achieves the braking effect by inserting the vertical brake pad into the vertical docking hole to prevent the wheel from rotating, but the wheel is moving at high speed when the vehicle is driving. At this time, when the vertical brake pad is inserted into the vertical docking hole, the wheel has huge power and may cause the vertical brake pad to deform, thereby causing the brake to lose control. Utility Model Content

[0006] The purpose of the utility model is to provide a brake positioning device for improving safety performance, so as to solve the problem that when the wheels of a vehicle are moving at high speed and the vertical brake pad is inserted into the vertical docking hole, the huge power of the wheel may cause the vertical brake pad to deform, thereby causing the brake to lose control.

[0007] In order to achieve the above-mentioned purpose of the utility model, the utility model adopts the following technical scheme: a brake positioning device for improving safety performance, comprising two protective cover tubes, connecting rods are arranged in the two protective cover tubes, brake pads are respectively connected to the two ends of the two connecting rods away from each other, and fixed covers are respectively connected to the two ends of the two protective cover tubes away from each other, and the fixed covers are arranged on the wheels of the baby carriage, and brake discs are arranged in the wheels of the baby carriage.

[0008] Preferably, positioning rings are fixed to the outer walls of the two ends of the two protective cover tubes that are close to each other, and fixing blocks are fixed on the positioning rings. Fixing rods are connected between the fixing blocks. A swivel is rotatably provided on the outer wall of the fixing rod, and a pedal is fixedly connected to the swivel.

[0009] Preferably, a docking hole is provided on the outer wall of the protective cover tube, and second sliding grooves are respectively provided at two ends of the two connecting rods close to each other, and the docking hole corresponds to the second sliding groove.

[0010] Preferably, a transmission rod is fixed to the bottom surface of the pedal, a driving block is fixed to the bottom end of the transmission rod, and the driving block corresponds to the second sliding groove.

[0011] Preferably, two first fixing holes are respectively formed on two sides of the two brake pads close to each other, and two second fixing holes are respectively formed on two sides of the fixing cover away from each other, and a return spring is connected between the first fixing hole and the second fixing hole.

[0012] Preferably, the outer wall of the fixed cover is rotatably connected with a rotating wheel, and the rotating wheel is connected to the wheel of the baby carriage.

[0013] Compared with the prior art, a brake positioning device for improving safety performance using the above technical solution has the following beneficial effects:

[0014] 1. Through the interaction of the pedal, transmission rod and drive block, fast and direct braking is achieved. The driver only needs to gently press the pedal to transmit force to the drive block through the transmission rod and push the connecting rod outward, thereby quickly pushing the brake pad to the brake disc. The response time from operation to actual braking is reduced. In addition, since the brake pad can contact the brake disc more quickly, the transmission of braking force is more efficient, thereby achieving higher braking efficiency and improving the safety performance of the baby stroller;

[0015] The brake disc inside the wheel of the baby carriage is extended inwards, and the brake pad is also extended outwards, thereby increasing the contact area between the brake pad and the brake disc, increasing the friction force, and making the braking effect more stable;

[0016] Second, the return spring ensures that the brake pad can quickly and automatically leave the brake disc and return to its initial position when not in use, making the brake pad reset smoother and avoiding excessive wear caused by long-term contact between the brake pad and the brake disc.

DETAILED DESCRIPTION

[0022] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings.

[0023] like Figure 1-Figure 4 As shown, a brake positioning device for improving safety performance includes two shield tubes 1, connecting rods 12 are arranged in the two shield tubes 1, brake pads 5 are connected to the two ends of the two connecting rods 12 away from each other, fixed covers 4 are connected to the two ends of the two shield tubes 1 away from each other, the fixed covers 4 are arranged on the baby carriage wheels 2, brake discs 3 are arranged in the baby carriage wheels 2, positioning rings 7 are fixed to the outer walls of the two shield tubes 1 at the two ends close to each other, fixing blocks 8 are fixed on the positioning rings 7, fixing rods 9 are connected between the fixing blocks 8, swivels 10 are rotatably arranged on the outer walls of the fixing rods 9, pedals 11 are fixedly connected to the swivels 10, docking holes 6 are opened on the outer walls of the shield tubes 1, second slide grooves 14 are opened at the two ends of the two connecting rods 12 close to each other, and the docking holes 6 correspond to the second slide grooves 14.

[0024] During use, the driver steps down on the pedal 11, which is fixed in the middle part of the protective cover tube 1 and connected to the transmission rod 16. When the pedal 11 is pressed down, it pushes the transmission rod 16 to move downward. There is a drive block 15 at the bottom end of the transmission rod 16, and this drive block 15 corresponds to the second slide groove 14 at the tail end of the connecting rod 12. As the drive block 15 slides downward along the second slide groove 14, the connecting rod 12 is pushed outward. The outward movement of the connecting rod 12 causes the brake pad 5 connected thereto to also move toward the brake disc 3 in the baby carriage wheel 2. The design of the brake pad 5 enables it to enter the interior of the brake disc 3. Once the brake pad 5 contacts the brake disc 3, the braking effect begins to occur due to the friction force. As the brake pad 5 continues to fit against the brake disc 3, the vehicle is finally stopped;

[0025] Through the interaction of the pedal 11, the transmission rod 16 and the drive block 15, a quick and direct braking is achieved. The driver only needs to lightly press the pedal 11 to transmit the force to the drive block 15 through the transmission rod 16 and push the connecting rod 12 to move outward, thereby quickly pushing the brake pad 5 toward the brake disc 3. The response time from operation to actual braking is reduced. In addition, since the brake pad 5 can contact the brake disc 3 more quickly, the transmission of the braking force is more efficient, thereby achieving higher braking efficiency and improving the safety performance of the baby stroller.

[0026] like Figure 2 Figure 3 As shown, a transmission rod 16 is fixed to the bottom surface of the pedal 11, and a driving block 15 is fixed to the bottom end of the transmission rod 16, and the driving block 15 corresponds to the second slide groove 14. The outer wall of the fixed cover 4 is rotatably connected to a rotating wheel 20, and the rotating wheel 20 is connected to the baby carriage wheel 2. Two first fixing holes 17 are respectively provided on both sides of the two brake pads 5 that are close to each other, and two second fixing holes 18 are respectively provided on both sides of the fixed cover 4 that are away from each other, and a return spring 19 is connected between the first fixing hole 17 and the second fixing hole 18.

[0027] During use, when the driver wants to release the brake, he lifts the foot pedal 11. At this time, the reset spring 19 between the first fixing hole 17 and the second fixing hole 18 on the fixed cover 4 begins to play a role. The reset spring 19 pulls the brake pad 5 back from the brake disc 3 by its elastic force, so that it moves toward the fixed cover 4, thereby realizing the reset of the brake pad 5. At the same time, the drive block 15 begins to slide upward along the second slide groove 14 under the action of the reset spring 19, pushing the transmission rod 16 to move upward. The upward movement of the transmission rod 16 drives the foot pedal 11 back to the initial position, thereby completing the reset process of the entire brake system. During the entire reset process, the foot pedal 11 fixed on the swivel 10 rises along with the rise of the transmission rod 16 until all parts return to the initial state, ready for the next braking operation;

[0028] The return spring 19 ensures that the brake pad 5 can quickly and automatically leave the brake disc 3 and return to the initial position when not in use, making the return of the brake pad 5 smoother and avoiding excessive wear caused by the brake pad 5 contacting the brake disc 3 for a long time.

[0029] The above are only preferred specific implementation methods of the utility model, but the protection scope of the utility model is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the utility model, who makes equivalent replacements or changes based on the technical scheme and utility model concept of the utility model, should be covered by the protection scope of the utility model.
