The wheels are connected to a steering shaft via a bracket. The steering shaft is drivenly connected to the handlebars and is coaxial with the turntable.

[0006] Furthermore, the wheels are motor-driven wheels.

[0007] Furthermore, a battery pack for powering the motor drive wheels is provided inside the seat.

[0008] Furthermore, the handlebars are located in front of the seat, and the handlebars are connected to one end of the steering gear set via a universal joint, while the other end of the steering gear set is connected to the steering shaft.

[0009] Furthermore, an arc-shaped through hole is provided on the turntable, through which a wire tube passes, and a limiting part is provided on the axial direction of the wire tube to limit the turntable.

[0010] Furthermore, a limit mechanism is provided between the vehicle frame and the turntable.

[0011] Furthermore, the limiting mechanism includes an electric pin.

[0012] Furthermore, the turntable is connected to a rotary drive motor.

[0013] The beneficial effects of this utility model are:

[0014] It can rotate independently and turn within a range of 0-360 degrees, making it flexible and convenient to operate and suitable for small-scale work machines in various situations. Attached Figure Description

Detailed Implementation

[0020] To better understand this utility model, the embodiments of this utility model will be explained in detail below with reference to Figures 1-4.

[0021] This utility model relates to a small, rideable work platform head unit, comprising wheels 1, a frame 2, and handlebars 3 and a seat 4 mounted on the frame 2. The structure of the frame 2, handlebars 3, and seat 4 is not limited to the only structure shown in the accompanying drawings; those skilled in the art can make adaptive modifications according to specific needs. Preferably, the wheels 1 of this utility model are motor-driven wheels. A battery pack 6 for powering the motor-driven wheels is disposed within the seat 4. Of course, the battery pack 6 is not limited to being within the seat 4 and can be disposed in other suitable locations outside the seat. As a preferred configuration of the seat structure, a baffle 401 is provided in front of the seat, and an operation panel 402 is provided on the baffle 401. The operation panel 402 contains control switches 403 for the head unit and other components mounted at the rear of the frame. Figure 1 shows a single wheel 1, but those skilled in the art can, according to conventional needs, provide two wheels 1.

[0022] The seat 4 is rotatably mounted on the frame 2 via a turntable 5. Specifically, the turntable preferably uses a rotary support, with its inner ring fixedly connected to the seat 4 and its outer ring fixedly connected to the frame 2. A fixing plate 201 is provided on the frame 2, and the outer ring of the rotary support is fixed to the fixing plate 201. The wheel 1 is connected to a steering shaft 102 via a bracket 101, and the steering shaft 102 is rotatably mounted on the frame 2. The steering shaft 102 is driven by the handlebars 3, allowing the wheel 1 to be steered. In this invention, the steering shaft 102 is coaxial with the turntable 5.

[0023] In a preferred embodiment, the handlebars 3 are located in front of the seat 4. The handlebars 3 are connected to one end of the steering gear set 8 via a universal joint (a bevel gear is provided below the universal joint), and the other end of the steering gear set 8 is meshed with a gear at the upper end of the steering shaft 102. The shaft of the steering gear set 8 is mounted on the base plate of the seat 4 via a bearing housing.

[0024] An arc-shaped through hole 202 is provided on the frame (if a fixed plate 201 is provided on the frame, the arc-shaped through hole 202 is provided on the fixed plate 201). A cable conduit 7 passes through the arc-shaped through hole 202, and a limiting part 701 is provided on the axial direction of the cable conduit 7 to limit the turntable 5. The cable conduit 7 provides a lead wire for the control line of the power unit at the rear of the frame. When the engine head rotates 360 degrees, if the cable conduit is fixed, the cable conduit 7 will block the steering gear set 8, resulting in incomplete steering of the engine head. Therefore, the above-mentioned arc-shaped through hole 202 is designed so that the cable conduit 7 can swing left and right along the arc-shaped through hole 202.

[0025] To provide positioning after the machine head rotates, this invention provides a limiting mechanism between the frame 2 and the turntable 5. Preferably, the limiting mechanism is an electric pin 9, with a corresponding positioning hole 501 on the turntable 5. Of course, the limiting mechanism can also be a manual pin.

[0026] The rotation method of the machine head of this utility model can be operated manually or electrically. If electric operation is used, a rotary drive motor is set on the frame 2, and the turntable 5 is driven and connected to the rotary drive motor. Specifically, the output shaft of the rotary drive motor is connected to the inner teeth of the inner ring of the rotary support.

[0027] It should be noted that although this specification describes the embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
