Technical Field

[0001] This utility model belongs to the field of children's vehicle technology, and specifically refers to a children's vehicle steering wheel structure that is easy to disassemble. Background Technology

[0002] There are various kinds of children's toy cars on the market, including children's bicycles, strollers, baby walkers, tricycles and four-wheeled toy cars. Nowadays, four-wheeled toy cars can simulate cars, allowing children to sit on them and move forward, backward and turn through an internal motor. Most of the steering wheels on the market are connected to the two front wheels of the toy car for steering, which is relatively troublesome to disassemble and assemble, and the structure is complicated. Utility Model Content

[0003] The purpose of this invention is to provide a stroller steering wheel structure that is reasonably structured, easy to assemble and disassemble, and does not require connecting the two front wheels of the stroller via a linkage, making it easy to disassemble.

[0004] The purpose of this utility model is achieved as follows:

[0005] A detachable steering wheel structure for a children's stroller includes a steering wheel, a hollow steering column, a steering sleeve, a guide sleeve, and a three-position self-resetting switch. The guide sleeve is fixed to the stroller's cover. One end of the hollow steering column is fixedly connected to the steering wheel, and the other end is detachably connected to the steering sleeve via a quick-release device. The lower end of the steering sleeve is connected to the working switch of the three-position self-resetting switch, and the switch body of the three-position self-resetting switch is connected to the guide sleeve.

[0006] In the aforementioned easily detachable stroller steering wheel structure, the quick-release device includes a U-shaped spring and a limiting protrusion. The limiting protrusion is located at the end of the spring, the U-shaped spring is located inside the hollow steering column, and the hollow steering column is provided with a through hole for the limiting protrusion to extend out. The steering sleeve is provided with a limiting hole that cooperates with the limiting protrusion, and the hollow steering column is provided with a pressing post for controlling the limiting protrusion to disengage from the limiting hole.

[0007] In the aforementioned easily detachable stroller steering wheel structure, a protective cover is provided on the pressing column.

[0008] In the aforementioned easily detachable stroller steering wheel structure, the U-shaped spring is made of stainless steel.

[0009] In the above-mentioned easily detachable stroller steering wheel structure, the U-shaped spring and the limiting protrusion are integrally formed.

[0010] In the aforementioned easily detachable stroller steering wheel structure, the steering wheel is made of transparent plastic.

[0011] In the above-mentioned easily detachable children's car steering wheel structure, the steering wheel includes a steering wheel body and a steering wheel end cover. The steering wheel end cover is screwed onto the steering wheel body and is used to hide the connection marks between the steering wheel body and the hollow steering column.

[0012] In the above-mentioned easily detachable children's stroller steering wheel structure, the steering wheel end cover is made of transparent material, and a decorative element is provided between the steering wheel body and the steering wheel end cover.

[0013] In the above-mentioned easily detachable stroller steering wheel structure, at least two hooks are provided at the lower end of the steering wheel end cover, and the steering wheel body is provided with a groove for cooperating with the hooks.

[0014] In the aforementioned easily detachable stroller steering wheel structure, the hook is an L-shaped structure, and its bend is provided with an inclined surface.

[0015] The outstanding and beneficial technical effects of this utility model compared to the prior art are:

[0016] This invention comprises a steering wheel structure consisting of a steering wheel, a hollow steering column, a steering sleeve, a guide sleeve, and a three-position self-resetting switch. The hollow steering column is fixedly connected to the steering wheel and detachably connected to the steering sleeve via a spring and a limiting protrusion. The hollow steering column is equipped with a pressing post that controls the limiting protrusion to detach from the steering sleeve's limiting hole. Pressing the pressing post allows the limiting protrusion to detach from the steering sleeve's limiting hole, thus detaching the hollow steering column from the steering sleeve. Operation is simple. Furthermore, this application uses a three-position self-resetting switch instead of a traditional linkage shaft, reducing installation difficulty. The three-position self-resetting switch is connected to the motors of the four wheels of the stroller. When rotation is needed, simply turn the steering wheel; the steering wheel controls the three-position self-resetting switch to rotate, which in turn controls the motor of the corresponding wheel to rotate. The overall structure is simple. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0024] like Figures 1-5 The diagram shows a detachable steering wheel structure for a children's stroller, comprising a steering wheel 1, a hollow steering column 2, a steering sleeve 3, a guide sleeve 4, and a three-position self-resetting switch 5. The guide sleeve 4 is fixed to the stroller's cover. One end of the hollow steering column 2 is fixedly connected to the steering wheel 1, and the other end is detachably connected to the steering sleeve 3 via a quick-release device 6. The lower end of the steering sleeve 3 is connected to the working switch of the three-position self-resetting switch 5. The switch body of the three-position self-resetting switch 5 is connected to the guide sleeve 4. Specifically, the guide sleeve is connected to the three-position self-resetting switch via a connecting ring. The quick-release device 6 includes a U-shaped spring 61 and a limiting protrusion 62. The limiting protrusion 62 is located at the end of the spring 61. The U-shaped spring 61 is located inside the hollow steering column 2, and the hollow steering column 2 has a through hole 6 for the limiting protrusion 62 to extend out. 3. The steering sleeve 3 is provided with a limiting hole 64 that cooperates with the limiting protrusion 62.
