Description

Technical Field

[0001] This utility model relates to the field of children's toy car manufacturing technology, and in particular to a wheel with a rotation locking structure for a twist car and a twist car. Background Technology

[0002] As a popular children's toy, the children's twist car is loved by children for its unique self-propelled mechanism and fun. However, existing children's twist cars have many safety hazards and inconveniences in their structural design. Most current twist cars use a free-rotating wheel design. This design makes it difficult for children to effectively lock the wheels when they encounter sudden situations and need to stop quickly or maintain stability while riding. This can easily lead to the twist car going out of control, causing collisions or falls, and other accidents. The safety risks are even more prominent for beginners with weaker driving skills.

[0003] In addition, the existing seat cushioning mechanism of the twist bike is not satisfactory. During the ride, especially when going over uneven roads, it cannot provide a good cushioning and shock absorption effect for children. This not only reduces the comfort of riding, but may also cause potential injury to children's bodies due to bumps and impacts.

[0004] Therefore, a wheel with a rotation locking structure and a twist car are needed. Utility Model Content

[0005] The main objective of this invention is to provide a wheel with a rotation locking structure for a scooter and a scooter in general, which can effectively solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A wheel with a rotation locking structure for a scooter includes a scooter body, a buffer assembly fixedly connected to the upper rear side of the scooter body, a rotating shaft rotatably connected to the front of the scooter body, a pressing assembly fixedly connected to the upper part of the rotating shaft, and a locking mechanism fixedly connected to the lower end of the rotating shaft through the upper side of the scooter body to the outside.

[0008] Preferably, the pressing assembly includes a handle, which is fixedly connected to the upper rear side of the rotating shaft. Oil pipes are fixedly connected to both the left and right ends of the handle. A fixing pipe is fixedly connected to the front end of each of the two oil pipes.

The end of each pressure block away from the piston disc on the same side extends through the outer surface of the fixing pipe on the same side to the outside. Both pressure blocks are slidably connected to the outer surface of the fixing pipe on the same side. A liquid guide pipe is fixedly connected to the lower rear side of each of the two oil pipes.

[0009] Preferably, the locking mechanism includes a fixed plate, which is fixedly connected to the lower left side of the rotating shaft. A wheel is rotatably connected to the outer surface of the fixed plate. A piston assembly is fixed to the upper left wall of the inner cavity of the fixed plate. A support block is fixedly connected to the lower part of the inner cavity of the fixed plate. Fixed blocks are fixedly connected to the front and rear of the upper end of the support block. Crescent-shaped discs are rotatably connected to the upper parts of the two fixed blocks. Friction discs are fixedly connected to the sides of the two crescent-shaped discs that are far apart from each other. Push plates are fixedly connected to the upper side between the opposing surfaces of the two crescent-shaped discs. A tension spring is fixedly connected to the upper side of the middle part between the opposing surfaces of the two crescent-shaped discs.

[0010] Preferably, the piston assembly includes a second fixing block, which is fixedly connected to the upper left wall of the inner cavity of the fixing plate.

[0026] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0027] Example 1, as Figures 1 to 6 As shown, a wheel with a rotation locking structure for a scooter includes a scooter body 1, a buffer assembly 2 fixedly connected to the upper rear side of the scooter body 1, a rotating shaft 5 rotatably connected to the front of the scooter body 1, a pressing assembly 3 fixedly connected to the upper part of the rotating shaft 5, and a locking mechanism 6 fixedly connected to the lower end of the rotating shaft 5 through the upper side of the scooter body 1 to the outside.

[0028] In the specific implementation of this utility model, the child first sits on top of the buffer component 2, then holds the internal structure of the pressing component 3 with both hands. The child then swings the pressing component 3, causing the rotating shaft 5 to swing. Simultaneously, the rotating shaft 5 swings, causing the locking mechanism 6 to swing, thus moving the entire device forward. During the movement, when encountering bumpy roads, the internal structure of the buffer component 2 effectively cushions the child's bumps. When the child encounters obstacles, uneven roads, or other situations requiring emergency stopping, pressing the internal structure of the pressing component 3 with both hands causes the internal structure of the pressing component 3 to move, simultaneously driving the internal structure of the locking mechanism 6 to move synchronously. Under the action of the internal structure of the locking mechanism 6, the device brakes quickly, greatly shortening the stopping time, effectively avoiding collisions and other accidents, and significantly improving riding safety.

[0029] Specifically, in order to achieve the goal of cushioning during children's riding, refer to Figure 6 In this solution, the buffer component 2 includes a circular groove 21, which is opened on the upper rear side of the scooter body 1. Several springs 22 are fixedly connected in a ring on the bottom wall of the inner cavity of the circular groove 21. The upper ends of the several springs 22 are fixedly connected to a seat plate 24. Several damping rods 23 are fixedly connected in a ring on the bottom wall of the inner cavity of the several circular grooves 21.

[0030] Furthermore, several damping rods 23 are located inside the spring 22 on the same side.

[0031] In the above scheme, during the movement of the entire device, the child sits on the seat 24, and when encountering bumpy road sections, the spring 22 and damping rod 23 work together to effectively absorb and buffer the vibration from the ground, providing a stable riding environment for the child and preventing the child from losing balance and falling due to severe vibration.

[0032] Example 2: In order to enable children to brake quickly while riding, refer to... Figure 2 In this solution, the pressing component 3 includes a handle 31, which is fixedly connected to the upper rear side of the rotating shaft 5. Oil pipes 32 are fixedly connected to the left and right ends of the handle 31. Fixed pipes 33 are fixedly connected to the front ends of the two oil pipes 32. Piston discs 35 are slidably connected to the inner cavities of the two oil pipes 32. Pressing blocks 34 are fixedly connected to the front ends of the two piston discs 35. The ends of the two pressing blocks 34 away from the piston discs 35 on the same side extend through the outer surface of the fixed pipes 33 on the same side to the outside. The two pressing blocks 34 are slidably connected to the outer surface of the fixed pipes 33 on the same side. Liquid guide pipes 36 are fixedly connected to the lower rear side of the two oil pipes 32.

[0033] In the above scheme, hydraulic oil is first filled into the inner cavities of the oil pipe 32 and the guide pipe 36. Then, when the child needs to brake while riding, he / she hooks the pressure block 34 backward with his / her finger, which pushes the piston disc 35 backward. The piston disc 35 then squeezes the hydraulic oil inside the inner cavity of the oil pipe 32 backward into the guide pipe 36. The hydraulic oil in the guide pipe 36 then flows into the internal structure of the locking mechanism 6, thereby causing the internal structure of the locking mechanism 6 to move and form a braking operation. This greatly shortens the stopping time, effectively avoids accidents such as collisions, and significantly improves riding safety.

[0034] Specifically, in order to achieve rapid braking, refer to Figure 4 and Figure 5 In this scheme, the locking mechanism 6 includes a fixed plate 61, which is fixedly connected to the lower left side of the rotating shaft 5. A wheel 62 is rotatably connected to the outer surface of the fixed plate 61. A piston assembly 69 is fixedly fixed to the upper left wall of the inner cavity of the fixed plate 61. A support block 63 is fixedly connected to the lower part of the inner cavity of the fixed plate 61. Fixed blocks 64 are fixedly connected to the front and rear of the upper end of the support block 63. A crescent plate 65 is rotatably connected to the upper part of the two fixed blocks 64. A friction plate 66 is fixedly connected to the side of the two crescent plates 65 that are far apart from each other. A push plate 68 is fixedly connected to the upper side between the opposite surfaces of the two crescent plates 65. A tension spring 67 is fixedly connected to the upper side of the middle between the opposite surfaces of the two crescent plates 65.

[0035] In the above scheme, hydraulic oil flowing downward through the guide pipe 36 enters the internal structure of the piston assembly 69, and then the internal structure of the piston assembly 69 moves to push the two push plates 68 away from each other. At the same time as the two push plates 68 move away from each other, they push the two crescent-shaped discs 65 to rotate around the fixed block 64 on the same side. Then, the two crescent-shaped discs 65 drive the two friction discs 66 to rotate and come into contact with the inner wall of the rotating wheel 62, thereby forming friction braking, so that the wheel 62 gradually stops rotating and achieves the purpose of braking.

[0036] Specifically, in order to achieve the goal of driving the two push plates 68, refer to Figure 5 In this scheme, the piston assembly 69 includes a second fixing block 691, which is fixedly connected to the upper left wall of the inner cavity of the fixing plate 61. The right end of the second fixing block 691 is fixedly connected to a piston tube 692. The left and right sides of the inner cavity of the piston tube 692 are both fixedly connected to piston columns 693. The middle right side of the piston tube 692 is fixedly connected to an inlet pipe 694.

[0037] Furthermore, the right end of the inlet pipe 694 extends through the inner wall of the same-side fixed block 691 to the outside, and the end of the guide pipe 36 away from the same-side oil pipe 32 is fixedly connected to the right end of the inlet pipe 694. The ends of the two piston rods 693 that are far apart from each other both extend through the inner wall of the same-side piston tube 692 to the outside.

[0038] In the above scheme, hydraulic oil enters the inner cavity of the inlet pipe 694 through the guide pipe 36, and then enters the middle of the inner cavity of the piston tube 692 through the inner cavity of the inlet pipe 694. The hydraulic oil entering the inner cavity of the piston tube 692 pushes the piston columns 693 on both sides away from each other, thereby pushing the two push plates 68 away from each other.

[0039] The case also disclosed a scooter with wheels featuring a rotation locking mechanism.
