Description

Technical Field

[0001] This utility model relates to the field of children's products, specifically an electric scooter, and more particularly to an electric scooter that uses a conductive rotating structure to enable flexible steering wheel rotation and avoid wire tangling. Background Technology

[0002] Traditional hoverboards rely primarily on manual steering to propel themselves, resulting in short distances and requiring considerable effort. While electric hoverboards have emerged, they still suffer from the following problems:

[0003] The steering wheel and drive unit are directly connected by wires, which makes the wires easy to get tangled when the steering wheel is turned, affecting flexibility and lifespan. Some electric scooters use a structure that connects the rotating disc with a metal copper sheet, which partially solves the tangling problem, but the structure is complex and inconvenient to maintain.

[0004] An unreasonable layout of power supplies and switches, such as an unoptimized circuit design for push-button switches, can lead to inconvenient operation or poor circuit stability.

[0005] Therefore, there is an urgent need for an electric scooter that is simple in structure, has stable electrical conductivity, and avoids wire tangling. Utility Model Content

[0008] An electric scooter includes a body, a drive unit, and a power source; the bottom of the body is provided with a rear wheel and a front wheel assembly; a steering wheel is provided on the top of the body, and a steering shaft located at the bottom of the steering wheel passes through the body and connects to the front wheel assembly; the front wheel assembly includes a drive wheel and a cage; the drive unit is located inside the cage and is used to drive the drive wheel to rotate; the power source is installed inside the body and supplies power to the drive unit; it also includes a switch and at least two conductive rotating structures; the two conductive rotating structures are conductive rotating structure a and conductive rotating structure b; both conductive rotating structure a and conductive rotating structure b are mounted on the steering shaft;

[0009] The conductive rotating mechanism includes a conductive inner ring, a conductive outer ring, and multiple conductive beads; both the conductive inner ring and the conductive outer ring are provided with annular grooves; the conductive beads are located within the area enclosed by the two annular grooves and can move freely along the annular grooves;

[0010] The power supply, foot switch, conductive rotating structure a, drive device, and conductive rotating structure b are connected by wires to form a closed loop.

[0011] Furthermore, the switch is a foot switch, installed above the foot pedal of the vehicle body; the main body of the foot switch is a foot pedal; one end of the foot pedal is hinged to the foot pedal of the vehicle body, and the other end is provided with a spring; the spring is located between the foot pedal and the foot pedal, providing a restoring force for the foot pedal.

[0012] Furthermore, an upper metal contact is provided at the bottom center of the foot pedal; a lower metal contact is provided at the top of the foot pedal; when the foot switch is pressed down, the upper metal contact and the lower metal contact are connected; the upper metal contact and the lower metal contact are respectively connected to the power supply and the conductive outer ring of the conductive rotating structure a through wires.

[0013] Furthermore, the conductive rotating structure a and the conductive rotating structure b are distributed vertically along the steering axis.

[0014] Furthermore, there is a gap between the conductive rotating structure a and the conductive rotating structure b.

[0015] Furthermore, a plastic gasket is provided between the conductive rotating structure a and the conductive rotating structure b for separation.

[0016] Furthermore, the steering shaft is hollow inside and is provided with conductive wire a and conductive wire b.

[0019] Furthermore, the conductive rotating structure a and the conductive rotating structure b are located in the same plane, with one of the conductive rotating structures located inside the other conductive rotating structure, and an annular plastic gasket between the two conductive rotating structures.

[0020] Furthermore, all the conductors are located outside the steering shaft.

[0021] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0022] Avoid wire tangling: By using a conductive rotating structure mounted on the steering shaft, and utilizing the free movement of conductive beads within the annular groove, continuous conductivity is achieved during steering wheel rotation, completely solving the traditional problem of wire tangling and improving the steering wheel's rotational flexibility and lifespan.

[0035] The present invention will now be further described with reference to the accompanying drawings.

[0036] To facilitate the understanding of the technical solution of this patent by those skilled in the art, and to make the technical purpose, technical solution and beneficial effects of this patent clearer, and to fully support the scope of protection of the claims, the technical solution of this patent will be further and more detailed below in the form of specific cases.

[0037] Example 1:

[0038] Reference Figure 1 This embodiment includes a vehicle body, rear wheels, a seat, a front wheel assembly, and a steering wheel. The wheels and front wheel assembly are mounted below the vehicle body, while the seat and steering wheel are located above the vehicle body. A foot switch is provided at the foot pedal position (foot pedal area) on the vehicle body.

[0039] Reference Figure 2 and Figure 1 The steering wheel is connected to the front wheel assembly via a steering shaft that runs through the vehicle body, with its top end connected to the steering wheel and its bottom end connected to the front wheel assembly. Two conductive rotating structures are mounted on the steering shaft, and all three are located on the same central axis. The steering shaft is rotatably connected to the vehicle body via these two conductive rotating structures, thus giving it a degree of freedom to rotate along its own central axis within the vehicle body.

[0040] Reference Figure 3 and Figure 2 In this embodiment, the front wheel assembly includes a drive wheel, a cage, and a drive unit; wherein the drive unit is located inside the cage and is used to drive the front wheel located outside the cage to rotate. The front wheel assembly is located behind the cage, and an auxiliary wheel is also provided in front of the cage. The specific structure of the front wheel assembly and how the drive unit drives the front wheel to rotate, thereby further driving the movement of the vehicle body, are common knowledge and will not be described in detail in this patent.

[0041] Reference Figure 4 and Figure 1 This embodiment provides a foot switch with a foot pedal located directly above the footrest of the vehicle body. One end of the foot pedal is hinged to the footrest of the vehicle body, and the other end is equipped with a spring. An upper metal contact is located at the bottom center of the foot pedal, and a lower metal contact is located at the top of the footrest. The spring is located between the foot pedal and the footrest. When pressure is applied to the foot pedal, the pedal rotates along the hinged position, compressing the spring. When the upper and lower metal contacts abut against each other, the circuit is connected, and power is supplied to the drive device, driving the front wheel to rotate. When the pedal is released, the spring retracts, the upper and lower metal contacts separate, the circuit is disconnected, and power supply stops.

[0042] Reference Figure 6To address the problem of wire entanglement, this embodiment designs a conductive rotating structure, which includes a conductive inner ring, a conductive outer ring, and multiple conductive beads. Both the inner and outer conductive rings have annular grooves; two annular grooves are joined to form an annular groove. The conductive beads are located within the annular groove and move freely along it. This conductive rotating structure not only provides support similar to a bearing but also functions as a component connecting circuits. In this embodiment, two conductive rotating structures are provided, with conductive rotating structure a positioned above conductive rotating structure b. Both are fitted onto the steering shaft, providing support and rotational freedom. Since there is a large gap between conductive rotating structures a and b, no separating plastic gasket is needed. If conductive rotating structures a and b are very close together, a plastic gasket is required.

[0043] For specific circuit connection details, please refer to... Figure 5 and Figure 2 The negative terminal of the power supply is connected to the lower metal contact of the foot switch via power supply wire a. The upper metal contact of the foot switch is connected to one end of conductive wire c. The other end of conductive wire c is electrically connected to the conductive outer ring of conductive rotating structure a. The conductive inner ring of conductive rotating structure a is connected to the negative terminal of the motor of the drive device via conductive wire a. The positive terminal of the motor is connected to the conductive inner ring of conductive rotating structure b via conductive wire b. The conductive outer ring of conductive rotating structure b is electrically connected to the positive terminal of the power supply via power supply wire b.

[0044] In this embodiment, the steering shaft is hollow inside, and conductive wires a and b are located inside the steering shaft to avoid tangling.

[0045] Example 2:

[0046] In this embodiment, the conductive rotating structure is exactly the same as the conductive rotating structure in Embodiment 1. The difference is that conductive rotating structure a and conductive rotating structure b are located in the same plane, and conductive rotating structure a is located in the inner region of conductive rotating structure b. An annular plastic washer is provided between the conductive inner ring of conductive rotating structure b and the conductive outer ring of conductive rotating structure a to isolate the circuit. See details below. Figure 7 .

[0047] This design eliminates the need to connect any wiring inside the steering shaft; each wire can be located outside the steering shaft. For specific connections, please refer to [reference needed]. Figure 8 .

[0048] For the purpose of simplifying the description, the disclosure of technical details in the above-described specific embodiments may only reach the level that a person skilled in the art can determine for themselves. That is, for the technical details not disclosed in the above-described specific embodiments, a person skilled in the art can complete them without any creative effort, with the full guidance of the patented technical solution and with the help of published documents such as textbooks, reference books, papers, patents, and audio-visual products. Alternatively, these details are content that a person skilled in the art can determine for themselves based on the actual situation, according to their common understanding. Therefore, even if these technical details are not disclosed, it will not affect the sufficiency of disclosure of the patented technical solution.

[0049] In summary, based on the interpretative role of the claims in this patent specification, any specific implementation that falls within the scope of the claims of this patent is within the protection scope of this patent.
