[0039] As Figures 1-5 shown, an adjustable shock-absorbing structure can be configured on a children's vehicle, specifically set near the rear wheel side. The rear wheel set 5 of the children's vehicle has a fixed seat 50, and this shock-absorbing structure can be detachably and fixedly connected to the fixed seat 50.

[0040] The adjustable shock-absorbing structure of this embodiment mainly includes: a mounting body 1, an adjustment knob 2, a shock-absorbing plate 3, and a sliding adjustment member 4.

[0041] The mounting body 1 is provided with an adjustment knob 2, and the adjustment knob 2 is provided with a gear 20. Specifically, the adjustment knob 2 and the gear 20 are connected by a connecting rod. One end of the connecting rod is fixedly connected to the adjustment knob 2, and the other end of the connecting rod is fixedly connected to the gear 20. When the adjustment knob 2 rotates, it can drive the gear 20 to rotate synchronously through the connecting rod.

[0042] One end of the shock-absorbing plate 3 is connected to the mounting body 1. The shock-absorbing plate 3 is detachably and fixedly connected to the lower part of the mounting body 1 by bolts for convenient replacement and disassembly. The other end of the shock-absorbing plate 3 can be connected to the rear wheel set 5 of the children's vehicle during actual use, specifically connected to the fixed seat 50 on the rear wheel set 5. Similarly, the shock-absorbing plate 3 can be detachably and fixedly connected to the fixed seat 50 by bolts for convenient disassembly and replacement.

[0043] The sliding adjustment member 4 is movably arranged on the installation body 1, and the sliding adjustment member 4 is provided with a rack 40 which is integrally arranged or separately arranged therewith, that is, whether the rack 40 is integrally arranged with the sliding adjustment member 4 or separately arranged therewith, the present solution can be implemented. And the rack 40 is meshed with the gear 20 for transmission. The sliding adjustment member 4 is provided with a supporting portion 411, and the supporting portion 411 is movably abutted against the shock-absorbing plate 3. By changing the abutting position of the supporting portion 411 on the shock-absorbing plate 3, the softness and hardness adjustment of the shock-absorbing structure, that is, the adjustment of the shock-absorbing effect is achieved. Specifically, the sliding direction of the sliding adjustment member 4 is the same as the length direction of the shock-absorbing plate 3, and the abutting position of the supporting portion 411 on the shock-absorbing plate 3 is adjustable along the length direction of the shock-absorbing plate 3.

[0044] Specifically, the installation body 1 of this embodiment is a pipe fitting, which is hollow, and the hollow part is its installation cavity, which can be used for the installation of other components. The gear 20 is in the installation cavity, the adjusting knob 2 is outside the installation cavity, and the adjusting knob 2 has a connecting rod fixedly connected to it, which extends from the outside to the inside into the installation cavity and is connected to the gear 20. The rack 40 is at one end of the sliding adjustment member 4, and the rack 40 is in the installation cavity; the abutment portion 411 is at the other end of the sliding adjustment member 4, specifically, the end of the sliding adjustment member 4 away from the rack 40 has a boss 41, and the abutment portion 411 is on the boss 41, which can prevent the sliding adjustment member 4 from sliding into the installation body 1 completely, and ensure that it is convenient to abut against the shock-absorbing plate 3. The installation body 1 is in the form of a pipe fitting, and the sliding adjustment member 4 is movably inserted into one end of the installation body 1.

[0045] Combination Figures 3-5 As shown, during actual use, when the adjusting knob 2 is rotated, the gear 20 can engage with the rack 40 to drive the sliding adjustment member 4 to telescopically move relative to the mounting body 1, so as to adjust the abutment position of the abutment portion 411 on the shock absorbing plate 3, thereby adjusting the hardness of the shock absorbing structure, that is, the shock absorbing effect of the shock absorbing structure.

[0046] Specifically, when the adjusting knob 2 is turned clockwise, the abutting position of the abutting portion 411 on the shock absorbing plate 3 gradually moves away from the installation body 1, and the shock absorbing structure gradually becomes harder. When the adjusting knob 2 is turned counterclockwise, the abutting position of the abutting portion 411 on the shock absorbing plate 3 gradually moves closer to the installation body 1, and the shock absorbing structure gradually becomes softer.

[0047] Alternatively, when the adjusting knob 2 is turned clockwise, the abutting position of the abutting portion 411 on the shock absorbing plate 3 gradually approaches the mounting body 1, and the shock absorbing structure gradually becomes softer. When the adjusting knob 2 is turned counterclockwise, the abutting position of the abutting portion 411 on the shock absorbing plate 3 gradually moves away from the mounting body 1, and the shock absorbing structure gradually becomes harder.

[0048] In this embodiment, an adjustment knob 2 is provided on the installation main body 1, a gear 20 is provided on the adjustment knob 2, a rack 40 is provided on the sliding adjustment member 4, and the gear 20 meshes with the gear 20 for transmission. When the adjustment knob 2 is rotated, the adjustment knob 2 meshes with the rack 40 through the gear 20, driving the sliding adjustment member 4 to move telescopically relative to the installation main body 1, and the abutting position of the abutting portion 411 on the sliding adjustment member 4 on the shock-absorbing plate 3 also changes accordingly, thereby achieving the purpose of adjusting the shock-absorbing intensity of the shock-absorbing structure. Through the cooperation of the gear 20 and the rack 40, the shock-absorbing intensity of the shock-absorbing structure can be steplessly adjusted, and the adjustment range is wide; and the user only needs to rotate the adjustment knob 2 with one hand to adjust the shock-absorbing intensity, without the need for both hands to operate, and the adjustment is convenient; and the overall structure of the shock-absorbing structure is simple.
