Description

Technical Field

[0001] This utility model relates to the field of children's bicycle auxiliary support technology, and in particular to a children's bicycle rear wheel auxiliary support and stabilization structure. Background Technology

[0002] With parents placing greater emphasis on developing children's motor skills and the growth of the children's bicycle market, there is an urgent need for an auxiliary structure that can provide stable support for young children, reduce the risk of falls, and not hinder the development of their balance perception. Against this backdrop, the children's bicycle rear wheel auxiliary support and stabilization structure (i.e., the auxiliary wheel) has emerged. By adding adjustable-height support wheels to both sides of the bicycle's rear wheel, it utilizes the three-point balance principle (two auxiliary wheels + the rear wheel) to keep the bicycle in a vertical position at all times. This allows children to safely practice pedaling and steering without parental assistance, gradually building their confidence in riding. It has become a key transitional design for young children from "getting in touch with a bicycle" to "mastering balance."

[0003] The connection angle and support height between the training wheels and the vehicle body are usually fixed or have limited adjustment. They can only provide stable support when the vehicle body is kept in a nearly vertical position. When children actively tilt their bodies while riding (such as when trying to turn or avoid obstacles) or the road surface is slightly tilted, the training wheels cannot dynamically adjust the support angle according to the posture of the vehicle body. At this time, one training wheel may deform due to excessive force, or the other training wheel may lift off the ground in advance, which will disrupt the balance and increase the risk of tilting.

[0004] Therefore, we provide a rear wheel auxiliary support and stabilization structure for children's bicycles to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a rear wheel auxiliary support and stabilization structure for children's bicycles, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rear wheel auxiliary support and stabilization structure for a children's bicycle, comprising an inclined fixed support rod and an anti-tilt double-layer buffer support and stabilization mechanism, wherein the anti-tilt double-layer buffer support and stabilization mechanism is provided on the lower side of the inclined fixed support rod; The anti-tilt double-layer buffer support and stabilization mechanism includes an elastic buffer positioning component, an auxiliary wheel movable positioning component, and an anti-tilt movable stabilization component. An elastic buffer positioning component is provided on the lower side of the inclined fixed support rod, an auxiliary wheel movable positioning component is provided on the lower side of the elastic buffer positioning component, and an anti-tilt movable stabilization component is provided on one side of the auxiliary wheel movable positioning component.

[0007] Preferably, the elastic buffer positioning assembly includes a T-shaped steel bracket, a fixed support top plate, a central movable telescopic support rod, a sleeved buffer spring, and a bottom positioning clamp. The lower middle of the inclined fixed support rod is fixedly connected to the T-shaped steel bracket, and the lower two sides of the T-shaped steel bracket are fixedly connected to the fixed support top plate. The central movable telescopic support rod is movably sleeved at the lower middle of the fixed support top plate, and a sleeved buffer spring is sleeved on the surface of the fixed support top plate. The lower two ends of the T-shaped steel bracket are fixedly connected to the bottom positioning clamp.

[0008] Preferably, the auxiliary wheel movable positioning assembly includes an auxiliary wheel positioning support rod and a movable clamping bracket. The lower end of the fixed support top plate is fixedly connected to the auxiliary wheel positioning support rod, and a movable clamping bracket is welded and fixed to one side of the auxiliary wheel positioning support rod. The auxiliary wheel positioning support rod is movably connected to the bottom positioning clamping plate through the movable clamping bracket.

[0009] Preferably, the anti-tilt movable stabilizing component includes a fastening positioning bolt, an auxiliary wheel stabilizing frame, and a sleeved anti-slip rubber sleeve. One side of the auxiliary wheel positioning support rod is threaded with a fastening positioning bolt, the surface of the fastening positioning bolt is sleeved with the auxiliary wheel stabilizing frame, and the outer side of the auxiliary wheel stabilizing frame is sleeved with a sleeved anti-slip rubber sleeve.

[0010] Compared with the prior art, the beneficial effects of this utility model are: As shown in the figure, the anti-rollover double-layer buffer support stabilization mechanism features a fixed support plate at the bottom of the T-shaped steel bracket, with a movable and telescopic central support rod inside. A buffer spring at the outer end restricts the internal telescopic movement. Auxiliary wheel positioning components are installed on both sides of the T-shaped steel bracket. During turning, the outer tire pushes upwards, causing the upper elastic buffer positioning component to extend inwards. The internal buffer spring restricts the tilt angle of the lower tire, while the inner tire extends downwards to contact the ground. This ensures that both tires maintain real-time contact with the ground, guaranteeing good grip for the auxiliary tires during turning and preventing rollover. Attached Figure Description
