[0036] The present invention will be further described below with reference to the accompanying drawings and implementation examples.

[0037] First embodiment:

[0038] Please refer to Figures 1-4 In the first embodiment of the present utility model, the brake and shock-absorbing structure of the baby stroller includes: two shock-absorbing seats 1, shock-absorbing springs 2 are fixedly installed on the two shock-absorbing seats 1, connecting seats 3 are rotatably installed on the two shock-absorbing seats 1, the bottom ends of the two shock-absorbing springs 2 are fixedly connected to the two connecting seats 3 respectively, the same fixed tube 4 is fixedly installed between the two connecting seats 3, a connecting sleeve 5 is rotatably installed on the side of the two connecting seats 3 close to each other, the two connecting sleeves 5 are adapted to the outer shapes of the two connecting seats 3, a driven tube 6 is fixedly installed between the two connecting sleeves 5, the driven tube 6 is rotatably sleeved on the fixed tube 4, and a brake pedal is fixedly installed on the connecting sleeve 5 on the right side. 7. Both connecting sleeves 5 are provided with a snap-in groove 8 and a circular groove 9. One side of the snap-in groove 8 is a sloped surface to facilitate the sliding in and out of the brake top rod 12 mentioned below. Both connecting sleeves 5 are provided with a mounting cavity 10. Pin rods 11 are fixedly installed in the two mounting cavities 10. Brake top rods 12 are slidably sleeved on the two pin rods 11. The ends of the two brake top rods 12 close to each other extend into the two snap-in grooves 8 respectively. Telescopic springs 13 are provided in the two mounting cavities 10. The two telescopic springs 13 are respectively sleeved on the two pin rods 11. The two ends of the two telescopic springs 13 are respectively in contact with the two brake top rods 12 and the inner wall of one side of the two mounting cavities 10.

[0039] In order to reserve sufficient space for movement and ensure the stability of the installation of the two shock-absorbing springs 2, in this method, an installation groove is opened on one side of the two connecting seats 3, and a docking round rod is fixedly installed on the inner wall of the two installation grooves. The two docking round rods are respectively rotatably connected to the two shock-absorbing seats 1, and rivet one is fixedly installed on the two shock-absorbing seats 1, and rivet two is fixedly installed on the two connecting seats 3. The two rivets one and the two rivets two are respectively fixedly connected to the top and bottom ends of the two shock-absorbing springs 2.

[0040] In this embodiment

[0041] The two shock-absorbing springs 2 are installed between the two shock-absorbing seats 1 and the two connecting seats 3. Once the baby stroller is bumped during driving, the impact force generated will cause the two shock-absorbing seats 1 and the two connecting seats 3 to have rotational contact. During the rotation between the four, the two shock-absorbing springs 2 will be pressed, causing the two shock-absorbing springs 2 to gradually deform. The two shock-absorbing springs 2 consume the energy generated by the vibration, thereby reducing the shaking feeling of the baby stroller to a certain extent and playing a shock-absorbing role.

[0042] When the baby stroller is moving, the two brake push rods 12 slide and get stuck in the two snap-in grooves 8 respectively. Once the baby stroller needs to be stopped, one side of the brake pedal 7 needs to be stepped down. The brake pedal 7 will drive the driven tube 6 to rotate on the fixed tube 4 through the two connecting sleeves 5. During the rotation of the two connecting sleeves 5, the positions of the two snap-in grooves 8 and the two circular grooves 9 will move. The two brake push rods 12 are gradually pushed by the two snap-in grooves 8, causing the two brake push rods 12 to gradually slide into the two mounting cavities 10, squeezing the two telescopic springs 13. The two brake push rods 12 are then gradually released from the squeeze and slid into the two circular grooves 9. After the two brake push rods 12 are inserted into the two circular grooves 9, the positions between the driven tube 6 and the two connecting seats 3 are fixed, thereby playing a braking role. Subsequently, the other side of the brake pedal 7 is stepped down to generate a pushing force in the opposite direction on the driven tube 6, so that the two brake push rods 12 can be moved out of the two circular grooves 9, thereby releasing the brakes.

[0043] Compared with the related art, the brake and shock-absorbing structure of the baby stroller provided by the present invention has the following advantages:

[0044] Beneficial effects:

[0045] In this method, two shock-absorbing springs 2 are added between the two shock-absorbing seats 1 and the two connecting seats 3, which can improve the shock-absorbing effect of the baby stroller on the original basis and improve the comfort of the baby stroller. By stepping on the brake pedal 7, the positions of the two brake push rods 12 are controlled, so that the two rear wheels can be braked at one time, which is more labor-saving and convenient to operate.

[0046] Second embodiment:

[0047] Based on the brake and shock-absorbing structure of the baby stroller provided in the first embodiment of the present application, the second embodiment of the present application provides another brake and shock-absorbing structure of the baby stroller. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the independent implementation of the first embodiment.

[0048] The second embodiment of the present invention will be further described below with reference to the accompanying drawings and implementation methods.

Similarly, a ring block 15 is fixedly sleeved on the connecting sleeve block 5 on the right, and a rectangular hole 16 is opened on the ring block 15. Two ring blocks 17 are rotatably installed on the connecting seat 3 on the right. An arc-shaped rack 18 is fixedly installed on the two ring blocks 17. Two vertical plates 19 are fixedly installed side by side on the top of the connecting seat 3. The same baffle 20 is fixedly installed on the top of the two vertical plates 19. The baffle 20 can block the two circular gears 23 mentioned below and play a certain protective role. Two docking plates 21 are fixedly installed between the two docking plates 21. The same rotating rod 22 is rotatably installed between the two docking plates 21. Both ends of the rotating rod 22 are fixedly sleeved with a circular gear 23 , the two circular gears 23 are respectively engaged with the two arc-shaped racks 18, a circular gear 24 is fixedly provided on the rotating rod 22, and the circular gear 24 is located between the two docking plates 21. An electric push rod 1 25 is provided under the baffle 20, and a rectangular block 27 is slidably installed under the baffle 20. The output rod of the electric push rod 1 25 is fixedly connected to one side of the rectangular block 27, and a bar rack 26 is fixedly installed at the bottom of the rectangular block 27. The bar rack 26 is engaged with the circular gear 24, and the same fixed plate 28 is fixedly installed on the two annular blocks 2 17. An electric push rod 29 is provided on one side of the fixed plate 28. A sliding block 30 is fixedly installed on the output rod of the electric push rod 29, and a card-in block 31 is fixedly installed on the side of the sliding block 30 away from the electric push rod 2 29. The card-in block 31 is adapted to the rectangular hole 16.

[0050] In order to increase the smoothness of the rotation of the two annular blocks 17 and reduce wear, in this embodiment, multiple rolling balls are embedded on the inner walls of the two annular blocks 17, and the multiple rolling balls are in rotational contact with the connecting seat 3.

[0051] In order to ensure the stability of the installation of the electric push rod 25, in this method, a pad 1 is fixedly installed on the bottom of the baffle 20, and two U-shaped clamps 1 are fixedly installed on the bottom of the pad 1. The two U-shaped clamps 1 are fixedly connected to the electric push rod 25.

[0052] In order to support the rectangular block 27 and limit the movement range of the rectangular block 27 to prevent it from falling off the baffle 20, in this method, a strip hole is opened on the baffle 20, and a limit block is slidably installed in the strip hole. The bottom of the limit block is fixedly connected to the top of the rectangular block 27, and a support block is fixedly installed on the top of the limit block, and the support block is slidably connected to the top of the baffle 20.

[0053] In order to ensure the stability of the position of the electric push rod 29 and the sliding block 30, in this method, a pad 2 is fixedly installed on one side of the fixed plate 28, and two U-shaped clamps 2 are fixedly installed on one side of the pad 2. Both U-shaped clamps 2 are fixedly connected to the electric push rod 29, and two U-shaped rods are fixedly installed on one side of the fixed plate 28. Both U-shaped rods are slidably connected to the sliding block 30.

[0054] In this embodiment

[0055] Considering that in real life, there are often cases where baby strollers slide randomly on uneven roads due to momentary negligence and forgetting to brake, causing accidents, it is necessary to add an emergency brake mechanism to the baby stroller for quick braking in an emergency.

[0056] Once the brakes are forgotten and the stroller slides on the road by itself and is difficult to catch up, the parent can immediately press the remote control switch carried with them. At this time, the electric push rod 29 and the electric push rod 1 25 will be started in succession. After the electric push rod 29 is started, the output rod will gradually output outwards, pushing the sliding block 30 and the snap-in block 31 to move together. The snap-in block 31 will gradually slide and snap into the rectangular hole 16. Then the electric push rod 29 will automatically close and the snap-in block 31 will remain in place.

[0057] Then the electric push rod 1 25 starts to start, and the output rod of the electric push rod 1 25 gradually retracts inward, driving the rectangular block 27 fixed to it to slide, and the rectangular block 27 drives the bar rack 26, and the bar rack 26 drives the circular gear 2 24 meshing with it, and the circular gear 2 24 then drives the two circular gears 1 23 through the rotating rod 22, and the two circular gears 1 23 drive the two arc-shaped racks 18 meshing with it, and the two arc-shaped racks 18 then drive the two annular blocks 2 17 to rotate. Since the snap-in block 31 has been snapped into the rectangular hole 16 at this time, the two annular blocks 2 17 will maintain a fixed connection with the connecting block 5 on the right side through the annular block 1 15. Therefore, the two annular blocks 2 17 will drive the two connecting blocks 5 to rotate together, and the connecting block 5 will re-trigger the brake mechanism, so that the baby stroller automatically completes the brakes.

[0058] The above are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification and drawings, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
