[0032] See Figures 1 to 4The shock-absorbing structure in this embodiment mainly includes a main body and an elastic element. The main body includes a first connecting member 1 and a second connecting member 2. The first connecting member and the second connecting member are connected in a relatively telescopic manner. The elastic element is disposed between the first connecting member and the second connecting member. A rotating clamping structure is provided between the first connecting member and the second connecting member.

[0033] In this embodiment, the rotating clamping structure includes a snap-fit ​​hole groove structure provided on one of the first connector and the second connector, and a snap-fit ​​portion provided on the other.

[0034] Specifically, the snap-fit ​​slot structure is an N-shaped structure, wherein the middle oblique stroke of the N-shape can extend horizontally or obliquely. It includes an inlet section 31 for the snap-fit ​​part to enter, a rotating movable section 32 for the snap-fit ​​part to move when the first connector and the second connector rotate relative to each other, and a telescopic movable section 33 for the snap-fit ​​part to snap into and for the snap-fit ​​part to move therein when the first connector and the second connector extend relative to each other. The inlet section and the telescopic movable section extend along the extension and retraction directions of the first connector and the second connector, and the rotating movable section extends along the rotation direction of the first connector and the second connector, preferably perpendicular to the inlet section and the telescopic movable section.

[0035] More specifically, both the first connector and the second connector are hollow tubular structures with one end closed. The bottom wall of the first connector and the top wall of the second connector form a blocking part 4. The first connector is sleeved between the first connectors. The snap-fit ​​groove structure is provided on the first connector, the snap-fit ​​part is provided on the second connector, and the elastic element is provided between the first connector and the snap-fit ​​part; or, if the snap-fit ​​part does not obstruct the elastic element, the elastic element is provided between the blocking part of the first connector and the second connector.

[0036] More specifically, the snap-fit ​​part is a pin 5 horizontally disposed in the second connector, and the two ends of the pin are respectively fixed to the mounting holes 21 on the tube wall of the second connector. The elastic element is a compression spring 6 disposed in the first connector. One end of the compression spring abuts against the blocking part of the first connector and the other end abuts against the snap-fit ​​part. An active space 7 is formed in the second connector on the side of the snap-fit ​​part away from the elastic element, allowing the first connector to extend and retract.

[0037] During installation, the internal compression spring is placed in the first connector, and the external compression spring is sleeved on the first and second connectors. The upper end of the first connector is inserted into the second connector from the lower end. The horizontally arranged pin inside the second connector is aligned with the inlet section of the first connector. Then, the first and second connectors are pressed and compressed relative to each other, and then rotated relative to each other to allow the pin to move to the end of the rotating section and enter the telescopic section. After releasing, the telescopic section hooks the pin, and the pin can move up and down relative to the telescopic section when the first and second connectors are pressed and compressed relative to each other.

[0038] In other embodiments, the snap-fit ​​slot structure can also be an inverted L-shaped structure, wherein the horizontal stroke of the inverted L-shape can extend horizontally or diagonally. In this structure, the horizontal stroke forms an inlet segment and a rotating segment: it can be understood that the inlet segment and the rotating segment extend integrally in the same direction, or it can be understood that the inlet segment has no actual length and is only the opening of the rotating segment.

[0039] In other embodiments, the snap-fit ​​hole groove structure can be provided on the second connector, the snap-fit ​​part can be provided on the first connector, and the elastic element can be provided between the second connector and the snap-fit ​​part; or, the elastic element can be provided between the blocking part (bottom wall) of the first connector and the blocking part (top wall) of the second connector, and the pin can be replaced with a short protruding column or other components that do not affect or have little effect on the normal operation of the elastic element.

[0040] Furthermore, the outer walls of the first connector and the second connector are also provided with a ring of blocking portion. The elastic element also includes a compression spring sleeved on the outer walls of the first connector and the second connector. One end of the compression spring abuts against the blocking portion of the first connector and the other end abuts against the blocking portion of the second connector.

[0041] It should be noted that, in other embodiments, compression springs may be provided only inside or outside the first and second connecting members. It should also be noted that, when compression springs are provided inside the first and second connecting members, the compression springs on the outer walls of the first and second connecting members can be replaced with spring-shaped decorative parts, serving only a decorative purpose.

[0042] This shock absorption structure can be applied to children's electric vehicles or vehicle equipment that requires simple spring shock absorption, such as being installed between the frame and wheel frame of a children's electric vehicle. It has the advantages of simple structure and convenient assembly.

[0043] Furthermore, this application provides a children's electric vehicle using the above-mentioned shock absorption structure. The specific structure of the children's electric vehicle, such as the transmission mechanism, wheels, and frame, can be the existing conventional children's electric vehicle structure. Only the shock absorbers on the existing children's electric vehicles are replaced with the shock absorption structure of this application. The specific details are not elaborated here.

[0044] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
