Description

Technical Field

[0001] The utility model relates to a children's appliance, in particular to a children's sliding vehicle. Background Art

[0002] With the development of social economy and the improvement of people's living standards, children's toys, especially children's scooters, have become important tools for children's entertainment and exercise. Children's scooters can not only provide children with fun, but also help them develop balance and coordination skills to a certain extent. However, with the continuous improvement of the functionality and safety requirements for children's scooters, existing children's scooters have shown some limitations in meeting these requirements.

[0003] Generally speaking, traditional children's scooters are mainly composed of basic components such as chassis, wheels, and frames. These scooters are usually designed as fixed structures and lack effective shock absorption mechanisms. In actual use, when children slide on uneven roads, since the wheels are in direct contact with the ground, all vibrations and impact forces will be directly transmitted to the frame, which in turn affects the riding child. This will not only increase the child's discomfort during riding, but may also cause the child to lose control due to excessive vibration, increasing safety hazards.

[0004] In addition, due to the lack of an effective shock-absorbing mechanism, long-term sliding on rough roads may have a negative impact on the structural stability of the scooter, accelerate the wear of vehicle components, and shorten the service life of the scooter. Especially for children's scooters, considering the body structure and physiological characteristics of children, long-term vibration is also detrimental to the health of children's spine and joints. In addition, the existing children's scooters only have the function of riding and sliding, and the functions are relatively simple, so it is necessary to make further improvements to them. Utility Model Content

[0035] The electric heating oil removal device 7 is an electric heating network installed at the air inlet of the volute.

[0036] An oil collecting plate 8 is installed in the range hood body 1. The oil collecting plate 8 is provided with an inwardly recessed oil collecting area 81. The separation net 6 is located in the oil collecting area.

[0037] A docking post 11 extends downward from the bottom of the chassis 1, and the docking post 11 is docked with a docking hole 13 provided on the upper end surface of the seesaw 12. A fixing bolt 14 passes through the docking hole 13 and is connected to the docking post 11, thereby connecting the seesaw 12 and the chassis 1 as a whole.

[0038] Working principle: The children's scooter of this utility model is a newly designed entertainment and sports equipment, which aims to provide children with a safer, more comfortable and fun riding experience. Its core design concept is to achieve excellent shock absorption effect through a unique elastic support device, and provide children with a new way of interaction - jumping during riding.

[0039] The working principle of the utility model will be described in detail below. The children's slide car of the utility model is mainly composed of a chassis, wheels, a frame, an articulation device and an elastic support device. The chassis serves as a support platform for the entire vehicle, and wheels are installed at the bottom thereof to support the entire vehicle to slide on the ground. The frame is located above the chassis and is connected to the chassis through a specific articulation device, so that the frame can swing around the hinge point within a certain range. The elastic support device connects the frame and the chassis, provides a shock-absorbing function and allows the frame to bounce when subjected to a vertical force.

[0040] In the present invention, the core of the shock absorption mechanism is an elastic support device, which uses a spring as the main component. One end of the spring is fixed to the chassis and the other end is connected to the frame. When the wheel passes over an uneven road surface, the vibration and impact force generated are first transmitted to the chassis and then absorbed by the spring. The elastic properties of the spring enable it to compress when subjected to force, thereby buffering the vibration energy and preventing the entire impact force from acting directly on the frame and the passengers. When the vibration subsides, the spring will return to its initial state to ensure that the frame remains stable.

[0041] In addition to the shock-absorbing effect, the spring support device also gives the children's scooter a unique bouncing function. During the riding process, the child can exert a vertical downward force on the frame by moving the body up and down. This force compresses the spring, and when the force is removed, the spring releases energy, causing the frame to bounce upward. This bounce not only adds more fun to the children's riding, but also further improves the dynamic balance ability training of riding.

[0042] In order to limit the bouncing amplitude of the baby carriage, a buffer damper 73 is also provided between the frame and the chassis in the present case. The buffer damper 73 may be a hydraulic damping cylinder or a gas spring or other device, and no specific limitation is made here.

[0043] In addition, the design of the articulated device makes the connection between the frame and the chassis flexible. Through the cooperation of the articulated ears and the articulated seats, the frame can swing around the articulated point within a certain angle range. This design not only helps the shock absorber to work effectively, but also increases the controllability and stability of the scooter to adapt to different road conditions.

[0044] In order to ensure the stability of the structure and limit the swing range of the frame, the utility model also provides a guide rod and a limit hole. The guide rod extends downward from the bottom of the frame and passes through the limit hole on the chassis, limiting the swing range of the frame and preventing instability caused by excessive swinging. In addition, the design of the guide rod and the limit hole also helps to maintain the relative position between the frame and the chassis, ensuring the structural stability and safety of the scooter under any riding conditions.

[0045] In the present utility model, the design of the wheel has also been optimized, and an outward-facing wheel design is adopted. This design can not only improve the gliding efficiency of the scooter, but also increase the stability of the wheel's contact with the ground, further improving the safety and reliability of the entire vehicle. The use of outward-facing wheels, combined with the spring support and articulation device of the frame, forms a comprehensive system to ensure a smooth and comfortable riding experience under various road conditions. Due to the use of universal wheels, there is no need to install a steering device on the frame in this case. When using it, the user only needs to hold the handle on the frame and cooperate with the user's foot force to achieve steering, and even achieve on-the-spot U-turns, drifting and other actions, which enhances its fun. This eliminates the need for a complex steering system, helps reduce production costs, and improves market competitiveness.

[0046] In summary, the reasonable configuration of the hinge device and the elastic support device between the frame and the chassis in this case allows the frame to slightly swing and bounce relative to the chassis when subjected to vertical force, which not only improves the shock absorption effect, but also gives the scooter additional entertainment functions. This design allows children to use the scooter dynamically and diversely, which not only meets children's needs for riding comfort, but also increases the fun of riding.

[0047] Furthermore: by introducing an elastic support device between the frame and the chassis, the vibration and impact to children during riding are greatly reduced, reducing the potential safety risks caused by vibration. At the same time, the bouncing function of the frame has been carefully designed to ensure that it will not cause harm to children while providing fun, and the bouncing height and strength are within a safe control range.

[0048] The children's scooter of the utility model realizes the comprehensive embodiment of multiple benefits of shock absorption, safety and fun through the above series of design and structural optimization. This new type of children's scooter not only meets the high standards of modern families for the safety and entertainment of children's toys, but also demonstrates the technological innovation and progress in the field of children's toy design. By providing a more comfortable and safe riding experience, as well as increased interactive fun, the utility model is expected to become a popular new choice of children's scooters on the market, bringing more happiness and a healthy growth environment to children.

[0049] Further: Figure 8 , 9 As shown, a seesaw can also be installed at the bottom of the gliding car in this case. The specific installation method is that a docking column 11 extends downward from the bottom of the chassis 1, and the docking column 11 is docked with a docking hole 13 on the upper end surface of the seesaw 12. A fixing bolt 14 passes through the docking hole 13 and is connected to the docking column 11, so that the seesaw 12 and the chassis 1 are connected as a whole. At this time, children can use the arc-shaped contact surface of the seesaw with the ground to realize the function of the rocking car. When the user needs to use the sliding function, he only needs to remove the seesaw, thereby improving the functionality of this product.

[0050] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of the present invention.
