Abstract
Description
Technical Field
[0001] This utility model relates to the field of children's scooter technology, and in particular to a shock absorption device for children's scooter. Background Technology
[0002] As a popular outdoor toy car for children, the children's twist car, with its characteristic of not requiring electricity, motor or pedal drive, can not only satisfy children's fun of independent play, but also exercise their balance and physical coordination, making it the first choice for many families to buy toys for young children.
[0003] In real-world use, children often drive scooters on uneven surfaces such as community walkways and park paths. These surfaces may have minor bumps, depressions, or seams, which can cause vibrations when the scooter is in motion.
[0004] Most children's scooters on the market today have a rigid connection between the seat and the frame or are only equipped with simple sponge padding for cushioning. They lack an effective shock absorption structure specifically designed for road vibrations. When the scooter travels over uneven roads, the impact force on the wheels is directly transmitted through the frame to the seat, and then to the child's body. Since children's bones, spines and other body parts are not yet fully developed, their tolerance to vibration and impact is weak. Long-term or frequent vibrations will not only reduce the comfort of children riding, causing them to reduce their willingness to use the scooter due to discomfort, but may also have potential impacts on their physical development.
[0005] Therefore, a shock absorption device for children's scooters is needed to solve the above problems. Utility Model Content
[0006] The main purpose of this invention is to provide a shock absorption device for children's scooters, which can effectively solve the problems mentioned above.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A shock absorption device for a children's scooter includes a scooter body and a seat installed on the upper rear side of the scooter body. The scooter body has a cavity on its upper rear side, the seat is slidably disposed in the cavity, dampers and buffer springs connected to the bottom of the seat are respectively provided on the front and rear sides of the bottom wall of the scooter body, and a buffer mechanism connected to the seat is provided at the center of the bottom wall of the scooter body.
[0009] Preferably, both buffer springs are located on the same side of the outer ring of the damper.
[0010] Preferably, the buffer mechanism includes a connecting plate 1 installed at the bottom of the seat and the center of the bottom wall of the scooter body, respectively. The two connecting plates 1 are arranged opposite each other. Two fixing rods and four support plates are respectively provided on the front and rear sides of the two connecting plates 1 facing each other. Each fixing rod located on the same side is installed between the opposite surfaces of the corresponding two support plates, and the outer surfaces of the two fixing rods located on the same side are provided with a telescopic mechanism.
[0011] Preferably, the two telescopic mechanisms are symmetrically distributed front and back and a compression spring is provided between them.
[0012] Preferably, each of the telescopic mechanisms includes an arc-shaped rod one and two arc-shaped rods two. The end of the arc-shaped rod one away from the compression spring is installed in the middle of the outer surface of the upper fixed rod. The ends of the two arc-shaped rods two away from the compression spring are installed in the middle of the outer surface of the lower fixed rod and located on the left and right sides of the arc-shaped rod one. Circular holes are provided at both ends of the arc-shaped rod one and the two arc-shaped rods two. A rotating shaft is provided at the end of the arc-shaped rod one and the two arc-shaped rods two near the compression spring. Fixed plates are provided on both the left and right sides of the rotating shaft. The two fixed plates are respectively provided at both ends of the connecting plate two.
[0013] Preferably, both the first arc-shaped rod and the second arc-shaped rod are rotatably connected to the fixed plate through circular holes.
[0014] Preferably, the two ends of the compression spring are respectively connected to the middle of the two connecting plates two that are arranged opposite to each other.
[0015] Compared with the prior art, the present invention has the following beneficial effects:
[0016] 1. This utility model, through a shock-absorbing structure composed of a buffer spring, a damper, and a buffer mechanism, can achieve layered absorption and dissipation of vibration impact, forming a shock-absorbing system that sequentially performs initial buffering, energy dissipation, and residual absorption.

It also provides better protection for children's immature bones and spine, avoiding potential developmental risks caused by long-term vibration.
[0017] 2. The combination of connecting plate one, support plate and fixing rod in the buffer mechanism of this utility model can make the arc rod assembly stable. The arc rod one and arc rod two are connected by a rotating structure formed by the circular hole, fixing plate and connecting plate two, which not only ensures flexible deformation during buffering, but also avoids hard collision between parts. With the elastic reset function of the compression spring, wear between parts can be reduced and the service life of the overall device can be extended. Attached Figure Description

[0023] 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.
[0024] Example 1, as Figure 1 and Figure 2 As shown, a shock absorption device for a children's scooter includes a scooter body 1 and a seat 2 installed on the upper rear side of the scooter body 1. A cavity is provided on the upper rear side of the scooter body 1, and the seat 2 is slidably disposed in the cavity. A damper 4 and a buffer spring 3 connected to the bottom of the seat 2 are respectively provided on the front and rear sides of the bottom wall of the scooter body 1. A buffer mechanism 5 connected to the seat 2 is provided at the center of the bottom wall of the scooter body 1.
[0025] Furthermore, both buffer springs 3 are located on the outer ring of the damper 4 on the same side.
[0026] The buffer mechanism 5 in this device is installed between the seat cushion 2 and the scooter body 1 by bolt connection.
[0027] The specific workflow of this device is as follows:
[0028] The child sits on the upper part of the seat cushion 2, which is a soft cushion. When the child is driving the body 1 of the scooter, when the body 1 of the scooter travels on an uneven road surface, the impact force on the rear wheel of the body 1 of the scooter will be transmitted to the damper 4 through the buffer spring 3. The buffer spring 3 first performs initial buffering, converting some of the kinetic energy into elastic potential energy. The damper 4 then converts the energy generated during the compression and extension of the buffer spring 3 into heat energy through internal friction or fluid flow, thereby reducing the vibration amplitude of the scooter and providing a more comfortable riding experience for the child.
[0029] In the above embodiment, when the buffer spring 3 and the damper 4 move, the rear wheel position and bottom of the scooter body 1 will move upward, causing the seat 2 to slide in the cavity. At this time, the scooter body 1 and the seat 2 will squeeze the buffer mechanism 5, causing the buffer mechanism 5 to store kinetic energy, which will then be released to pull the damper 4 back to its initial state, thereby achieving the shock absorption effect and improving the stability of the scooter body 1 when it is in motion.
[0030] In the above embodiment, the buffer spring 3 and the damper 4 are combined to form a spring damper, which uses the existing technology model ZTA-240. The buffer mechanism 5 plays an auxiliary role, so that when the damper 4 returns to its initial state, it can be more stable.
[0031] In Example 2, furthermore, in order to improve the stability of the damper 4 during recovery through the buffer mechanism 5, and to reduce the impact of vibration when the child sits on the seat cushion 2, please refer to... Figure 3 and Figure 4 The buffer mechanism 5 includes a connecting plate 51 installed at the bottom of the seat cushion 2 and the center of the bottom wall of the scooter body 1 respectively. The two connecting plates 51 are arranged opposite each other. Two fixing rods 53 and four support plates 52 are respectively provided on the front and rear sides of the two connecting plates 51 facing each other. Each fixing rod 53 located on the same side is installed between the opposite surfaces of the corresponding two support plates 52, and the outer surfaces of the two fixing rods 53 located on the same side are provided with a telescopic mechanism 54.
[0032] Furthermore, the two telescopic mechanisms 54 are symmetrically distributed front and back and are connected by a compression spring 55;
[0033] Furthermore, each telescopic mechanism 54 includes an arc-shaped rod 541 and two arc-shaped rods 542. The end of the arc-shaped rod 541 away from the compression spring 55 is installed in the middle of the outer surface of the upper fixed rod 53. The ends of the two arc-shaped rods 542 away from the compression spring 55 are installed in the middle of the outer surface of the lower fixed rod 53 and located on the left and right sides of the arc-shaped rod 541. Both ends of the arc-shaped rod 541 and the two arc-shaped rods 542 are provided with circular holes 544. The ends of the arc-shaped rod 541 and the two arc-shaped rods 542 near the compression spring 55 are provided with a rotating shaft, and both sides of the rotating shaft are provided with fixing plates 545. The two fixing plates 545 are respectively provided at both ends of the connecting plate 543.
[0034] Furthermore, both the first arc rod 541 and the second arc rod 542 are rotatably connected to the fixed plate 545 through the circular hole 544;
[0035] Furthermore, the two ends of the compression spring 55 are respectively connected to the middle of the two connecting plates 543 that are arranged opposite to each other.
[0036] The specific workflow of buffer mechanism 5 is as follows:
[0037] When the rear wheel of the scooter body 1 is impacted, it will squeeze the damper 4, causing the seat 2 to slide in the cavity. At this time, the two connecting plates 51 will move closer to each other under pressure. Then, through the fixing rod 53, the arc rod 541 and the two arc rods 542 on the same side will rotate into a folded state. At this time, the arc rod 541 and the two arc rods 542 will push the connecting plate 543 through the fixing plate 545, causing the two connecting plates 543 to squeeze the connected compression spring 55, compress it, and generate elastic potential energy, thereby further improving the shock absorption effect of the device.
[0038] When leaving the uneven road section, the compression spring 55 releases pressure, pushing the two connecting plates 543 to move away from each other, causing the arc rods 541 and 542 on both sides to rotate into an unfolded state, and pushing the two connecting plates 51 through the fixing rod 53. Under the action of the damper 4, the seat cushion 2 is pushed back to its original position, achieving the effect of shock absorption.
[0039] In the above embodiments, the information regarding the material and elasticity of the compression spring 55 is well known to those skilled in the art and will not be repeated here.
[0040] The shock absorption process of this utility model is as follows:
[0041] First, the buffer spring 3 can quickly buffer the initial impact force generated by road bumps and depressions, converting some of the kinetic energy into elastic potential energy and reducing the direct transmission of impact.
[0042] Secondly, the damper 4 converts the excess energy generated during the compression and extension of the buffer spring 3 into heat energy through internal friction or fluid flow characteristics, effectively suppressing vehicle body resonance and preventing the vibration amplitude from amplifying.
[0043] Finally, the cushioning mechanism 54, through the synergistic action of the first arc rod 541, the second arc rod 542 and the compression spring 55, further absorbs the residual impact when the seat cushion 2 slides with vibration, and assists the seat cushion 2 to return to its stable state through the storage and release of elastic potential energy.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
