[0002] Children's scooter is a kind of sports equipment that is deeply loved by parents and children. It can not only bring entertainment to children, but also exercise children's limbs from an early age. The scooter not only brings endless fun to children's childhood, but also cultivates children's sports balance and coordination ability without knowing it.

[0003] There are many types of scooters in the prior art, but most of them have relatively simple functions. When the scooter passes through uneven roads, or when one side of the wheel suddenly encounters an obstacle, it is easy for the scooter to vibrate too much on one side and cause it to tilt and roll over, which is very detrimental to the safety of children. Therefore, in order to solve this problem, it is necessary to optimize the design of the product, and it is necessary to propose a new type of children's scooter. Utility Model Content

[0006] A hydraulic cylinder is fixedly installed on the top of the inner cavity of the sleeve, and a push rod fixedly connected to the movable rod is inserted and installed on the bottom of the hydraulic cylinder. The outer periphery of the push rod is located below the hydraulic cylinder and is sleeved with a shock-absorbing spring. A No. 1 piston is slidably installed in the hydraulic cylinder, and the bottom of the No. 1 piston is fixedly connected to the top of the push rod. A nitrogen cylinder is fixedly installed on the outside of the sleeve, and a connecting pipe connected to the top of the inner cavity of the hydraulic cylinder is fixedly connected to the top of the nitrogen cylinder. A branch ring is fixedly installed above the inner cavity of the nitrogen cylinder, and a No. 2 piston is slidably installed in the inner cavity of the connecting pipe located below the branch ring.

[0007] In a preferred embodiment, the left side of the fixing rod is connected to the rotating shaft via a bearing, the rotating shaft is fixedly connected to the inner ring of the bearing, and the fixing rod is fixedly connected to the outer ring of the bearing.

[0008] In a preferred embodiment, armrests are fixedly installed on both sides of the turntable, and rubber anti-slip pads are sleeved on the outer walls of the armrests.

[0009] In a preferred embodiment, a slot matching the movable rod is provided at the bottom of the sleeve, limiting convex strips are provided on both sides of the outer wall of the movable rod, and the movable rod and the limiting convex strips on the movable rod are plugged into the slot.

[0010] In a preferred embodiment, flow tubes passing through the branch ring are fixedly connected to both sides of the branch ring, a flow cavity is opened in the middle of the branch ring, the inner cavity of the branch ring is located below the flow cavity and is connected to an inverted trapezoidal sealing plug through a reset spring, and the inverted trapezoidal sealing plug is attached to the bottom of the branch ring.

[0011] In a preferred embodiment, the chamber above the No. 1 piston in the hydraulic cylinder is filled with hydraulic oil, and the chamber below the No. 2 piston in the nitrogen cylinder is filled with nitrogen.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0013] 1. In the present application, through the above design, since a roller is arranged on the left side of the bottom of the vehicle board, when the child sits on the seat, the turntable can be rotated by holding the armrest with the hand, and the roller located under the sleeve can be driven to rotate through the rotating shaft at the bottom of the turntable, thereby realizing the steering function. In addition, since a total of four rollers are arranged in the middle and right sides of the bottom of the vehicle board, the overall stability of the vehicle board can be increased.

[0014] 2. In the present application, through this design, when a child sits on the seat on the top of the vehicle board and pushes the ground with both feet to drive the vehicle board to slide as a whole, once the five rollers at the bottom of the vehicle board encounter an obstacle or roll on an uneven road surface, the rollers that encounter an obstacle or on an elevated road surface will be subjected to a force greater than that of other rollers, and will then be inserted into the sleeve to compress the shock-absorbing spring sleeved on the outer periphery of the push rod to balance the force. At this time, the five rollers can maintain relative balance to stabilize the vehicle board and prevent large-scale shaking. When the movable rod is inserted into the sleeve, the push rod will be driven to abut against the No. 1 piston and slide upward in the inner cavity of the hydraulic cylinder, so that the hydraulic oil in the inner cavity of the hydraulic cylinder located at the top of the No. 1 piston is squeezed and discharged into the nitrogen cylinder through the connecting tube. When the hydraulic oil reaches the upper part of the inner cavity of the nitrogen cylinder, it will continue to flow to the bottom of the shunt ring through the flow tubes running through the two sides of the shunt ring and the three channels of the flow cavity in the middle. In this process, the flow cavity is The inverted trapezoidal sealing plug will be squeezed by the hydraulic oil and stretch the return spring to move downward to open the channel of the flow cavity, so that the hydraulic oil can quickly flow into the chamber above the No. 2 piston in the nitrogen cylinder to squeeze the No. 2 piston to move downward to compress the nitrogen. This process releases the vibration load brought by the roller at this position. When the roller passes over an obstacle or an uneven base surface, the roller instantly loses the upward squeezing force. At this time, the nitrogen expansion at the bottom of the No. 2 piston and the rebound reset of the shock-absorbing spring on the periphery of the push rod will prompt all components to return to their original positions. At this time, the hydraulic oil in the nitrogen cylinder will reversely cross the branch loop and flow back into the hydraulic cylinder. In this process, the inverted trapezoidal sealing plug will be squeezed by the returning hydraulic oil and will be tightly abutted against the bottom of the flow cavity to close the flow cavity, so that the hydraulic oil can only flow back through the two flow tubes, thereby slowing down the reflux speed and achieving damping effect, so as to smoothly release the roller to return to its original position, thereby reducing rebound vibration.

[0021] Through the above design, since a roller 9 is set on the left side of the bottom of the vehicle board 1, when the child sits on the seat 2, the turntable 5 can be rotated by holding the armrest 6 with the hand, and the roller 9 located under the sleeve 7 can be driven to rotate through the rotating shaft 4 at the bottom of the turntable 5, thereby realizing the steering function. In addition, since a total of four rollers 9 are set in the middle and right sides of the bottom of the vehicle board 1, the overall stability of the vehicle board 1 can be increased.

[0022] Reference Figure 1 , 23. A hydraulic cylinder 10 is fixedly installed on the top of the inner cavity of the sleeve 7. A push rod 12 fixedly connected to the movable rod 8 is inserted and installed at the bottom of the hydraulic cylinder 10. The outer periphery of the push rod 12 is located below the hydraulic cylinder 10 and is sleeved with a shock-absorbing spring 13. A No. 1 piston 14 is slidably installed in the hydraulic cylinder 10, and the bottom of the No. 1 piston 14 is fixedly connected to the top of the push rod 12. A nitrogen cylinder 15 is fixedly installed on the outside of the sleeve 7. A connecting pipe 16 connected to the upper part of the inner cavity of the hydraulic cylinder 10 is fixedly connected to the top of the nitrogen cylinder 15. A splitter 15 is fixedly installed above the inner cavity of the nitrogen cylinder 15. The branch ring 17 has flow tubes 18 fixedly connected to both sides of the branch ring 17, and a flow cavity 19 is provided in the middle of the branch ring 17. The inner cavity of the branch ring 17 is located below the flow cavity 19 and is connected to an inverted trapezoidal sealing plug 20 through a reset spring, and the inverted trapezoidal sealing plug 20 is attached to the bottom of the branch ring 17. The inner cavity of the connecting tube 16 is located below the branch ring 17 and a No. 2 piston 21 is slidably installed thereon. The chamber above the No. 1 piston 14 in the hydraulic cylinder 10 is filled with hydraulic oil, and the chamber below the No. 2 piston 21 in the nitrogen cylinder 15 is filled with nitrogen.

[0023] With the above design, when a child sits on the seat 2 on the top of the vehicle board 1 and pushes the ground with both feet to drive the vehicle board 1 to slide as a whole, once the five rollers 9 at the bottom of the vehicle board 1 encounter an obstacle or roll on an uneven road surface, the roller 9 encountering an obstacle or on an elevated road surface will be subjected to a force greater than that of other rollers 9, and will then be inserted into the sleeve 7 to compress the shock-absorbing spring 13 sleeved on the outer periphery of the push rod 12 to balance the force. At this time, the five rollers 9 can maintain relative balance to stabilize the vehicle board 1. The fixed car plate 1 prevents a large shaking from occurring. When the movable rod 8 is inserted into the sleeve 7, the push rod 12 will be driven to abut against the No. 1 piston 14 and slide upward in the inner cavity of the hydraulic cylinder 10, so that the hydraulic oil in the inner cavity of the hydraulic cylinder 10 located at the top of the No. 1 piston 14 is squeezed and discharged into the nitrogen cylinder 15 through the connecting pipe 16. When the hydraulic oil reaches the upper part of the inner cavity of the nitrogen cylinder 15, it will continue to flow to the lower part of the shunt ring 17 through the flow pipes 18 penetrating the two sides of the shunt ring 17 and the flow cavity 19 in the middle. In this process, the flow cavity 19 The inverted trapezoidal sealing plug 20 below will be squeezed by the hydraulic oil and stretch the return spring to move downward to open the channel of the flow chamber 19, so that the hydraulic oil can quickly flow into the chamber above the No. 2 piston 21 in the inner cavity of the nitrogen cylinder 15 to squeeze the No. 2 piston 21 to move downward to compress the nitrogen. This process releases the vibration load brought by the roller 9 at this position. When the roller 9 passes over an obstacle or an uneven base surface, the roller 9 instantly loses the upward squeezing force. At this time, the nitrogen at the bottom of the No. 2 piston 21 expands to The rebound reset of the shock absorbing spring 13 on the periphery of the push rod 12 will prompt all components to return to their original positions. At this time, the hydraulic oil in the nitrogen cylinder 15 will reversely pass through the branch ring 17 and flow back into the hydraulic cylinder 10. During this process, the inverted trapezoidal sealing plug 20 will be squeezed by the returning hydraulic oil and will be tightly abutted under the flow cavity 19 to close the flow cavity 19, so that the hydraulic oil can only flow back through the two flow tubes 18, thereby slowing down the reflux speed and achieving a damping effect, so as to smoothly release the roller 9 to return to its original position, thereby reducing the rebound vibration.

[0024] The implementation principle of the embodiment of the present application is:

[0025] Firstly, since a roller 9 is arranged on the left side of the bottom of the vehicle board 1, when a child sits on the seat 2, the turntable 5 can be rotated by holding the armrest 6 with his hand, and the roller 9 located under the sleeve 7 can be rotated by the rotating shaft 4 at the bottom of the turntable 5, thereby realizing the steering function. In addition, since a total of four rollers 9 are arranged in the middle and right sides of the bottom of the vehicle board 1, the overall stability of the vehicle board 1 can be increased.

[0026] When a child sits on the seat 2 on the top of the vehicle board 1 and pushes the ground with his feet to drive the vehicle board 1 to slide as a whole, once the five rollers 9 at the bottom of the vehicle board 1 encounter an obstacle or roll on an uneven road surface, the roller 9 on the obstacle or elevated road surface will be subjected to a force greater than that of other rollers 9, and will then be inserted into the sleeve 7 to compress the shock-absorbing spring 13 sleeved on the outer periphery of the push rod 12 to balance the force. At this time, the five rollers 9 can maintain relative balance to stabilize the vehicle board 1 to avoid A large shaking occurs. When the movable rod 8 is inserted into the sleeve 7, it will drive the push rod 12 to abut against the No. 1 piston 14 and slide upward in the inner cavity of the hydraulic cylinder 10, so that the hydraulic oil in the inner cavity of the hydraulic cylinder 10 located at the top of the No. 1 piston 14 is squeezed and discharged into the nitrogen cylinder 15 through the connecting pipe 16. When the hydraulic oil reaches the upper part of the inner cavity of the nitrogen cylinder 15, it will continue to flow to the bottom of the shunt ring 17 through the flow pipes 18 passing through the two sides of the shunt ring 17 and the flow cavity 19 in the middle. In this process, the reverse flow below the flow cavity 19 The trapezoidal sealing plug 20 will be squeezed by the hydraulic oil and stretch the return spring to move downward to open the channel of the flow chamber 19, so that the hydraulic oil can quickly flow into the chamber above the No. 2 piston 21 in the inner cavity of the nitrogen cylinder 15 to squeeze the No. 2 piston 21 to move downward and compress the nitrogen. This process releases the vibration load brought by the roller 9 at this position. When the roller 9 passes over an obstacle or an uneven base surface, the roller 9 instantly loses the upward squeezing force. At this time, the nitrogen expansion at the bottom of the No. 2 piston 21 and the rebound reset of the shock-absorbing spring 13 on the outer periphery of the push rod 12 will prompt all components to return to their original positions. At this time, the hydraulic oil in the nitrogen cylinder 15 will reversely pass through the branch ring 17 and flow back into the hydraulic cylinder 10. In this process, the inverted trapezoidal sealing plug 20 will be squeezed by the returning hydraulic oil and will be tightly abutted against the bottom of the flow chamber 19 to close the flow chamber 19, so that the hydraulic oil can only flow back through the two flow tubes 18, thereby slowing down the reflux speed and achieving a damping effect, so as to smoothly release the roller 9 to return to its original position, thereby reducing the rebound vibration.

[0027] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
