Description

Technical Field

[0001] The present invention relates to the structure of a vehicle, and particularly refers to the structure of a vehicle that can rotate the tires of the vehicle and horizontally move the vehicle.

Background Art

[0002] In the conventional vehicle structure, since the vehicle tires can hardly rotate significantly, when parking, it is necessary to adjust the angle of the tires by backing up, which takes time. In addition, many existing vehicles are two-wheel drive, and only the front wheel part can rotate. With such a structure, the movement of the vehicle is greatly restricted.

[0003] On the other hand, in the prior art, by applying electromagnetic technology to the vehicle tire structure, the vehicle tires can be rotated 360 degrees to move horizontally. However, the tires using electromagnetic technology cannot freely run on general roads and must run on corresponding tracks.

[0018] Embodiments of the present invention will be described in more detail below with reference to the drawings and reference numerals, but this specification is intended to be implemented only after a person familiar with this art has thoroughly reviewed it.

[0019] Figure 1a is a schematic diagram illustrating the structure of an airwheel vehicle in a top view according to an embodiment of the present invention, Figure 1b is a schematic diagram illustrating the structure of an airwheel vehicle in a side view according to an embodiment of the present invention, Figure 2a is a schematic diagram illustrating the structure of an airwheel vehicle in a top view after tire steering according to an embodiment of the present invention, and Figure 2b is a schematic diagram illustrating the structure of an airwheel vehicle in a side view after tire steering according to an embodiment of the present invention. Referring to Figures 1a to 2b, in an embodiment of the present invention, the airwheel vehicle 1 includes a main body 10, at least one drive wheel 20, and a computer device 30. The bottom of the main body 10 is provided with a housing space 101. The drive wheel 20 is pivotally attached to the main body 10 by a control shaft 201 and installed in the housing space 101, and the diameter D1 of the housing space 101 is larger than the diameter D2 of the drive wheel 20 so as to provide rotational space for the drive wheel 20. The computer device 30 is installed inside the main body 10 and is electrically connected to the control shaft 201 and the drive wheel 20. The computer device 30 controls the drive wheel 20 to make a turn of 1 to 90 degrees using the control shaft 201, for example, a 90-degree right turn or a 90-degree left turn. In this embodiment of the present invention, the control shaft 201 is also pivotally attached to the main body 10, making it convenient for the control shaft 201 to rotate and move the drive wheel 20. However, in other embodiments of the present invention, a rail (not shown) may be installed at the bottom of the main body 10, for example, a concave type rail or a convex type rail may be installed, and the control shaft 201 can move on the rail to move the drive wheel 20.

[0020] In detail, when the air wheel vehicle 1 moves in a straight line, the drive wheel 20 can be held in the direction shown in Figure 1a. When the air wheel vehicle 1 moves horizontally, the drive wheel 20 can be rotated by the control of the computer device 30, and finally the drive wheel 20 can be turned in the direction shown in Figure 2a. In this way, the air wheel vehicle can move horizontally and park on the side of the road easily. In this embodiment, since the air wheel vehicle 1 has only one drive wheel 20, the drive wheel 20 is placed in the middle of the bottom of the main body 10, and the center of gravity of the entire air wheel vehicle 1 is adjusted to maintain balance for the air wheel vehicle with only one drive wheel 20. Furthermore, in other embodiments, multiple drive wheels 20 can be installed, and a drive wheel 20 with sufficient volume may be used to maintain the balance of the single-wheel air wheel vehicle 1.

[0021] On the other hand, since the drive wheel 20 is pivotally attached to the main body 10 by the control shaft 201, even if the drive wheel 20 is in contact with the ground, the computer device 30 can directly control the turn of the control shaft 201, further increasing the turn of the drive wheel 20. In other embodiments of the present invention, a motor device (not shown) can be further installed between the computer device 30 and the control shaft 201, thereby allowing the computer device 30 to rotate the control shaft 201 using the motor device, further increasing the rotational force.

[0022] Figure 3a is a schematic diagram illustrating the structure of an air wheel vehicle in a top view according to another embodiment of the present invention, Figure 3b is a schematic diagram illustrating the structure of an air wheel vehicle in a side view according to another embodiment of the present invention, and Figure 3c is a schematic diagram illustrating the structure of an auxiliary wheel in a top view according to another embodiment of the present invention. Referring to Figures 3a to 3c, in another embodiment of the present invention, the air wheel vehicle further includes an auxiliary wheel 40 comprising a ball wheel 401 and a bearing 403, the ball wheel 401 being ball-shaped and fitted into the bearing 403, the bearing 403 being connected to the bottom of the main body 10 by a connecting shaft 405, the bearing 403 constraining the ball wheel 401 within the bearing 403 and allowing the ball wheel 401 to roll freely, and the auxiliary wheel 40 and the drive wheel 20 are installed facing each other at the bottom of the main body 10. Furthermore, the number of connecting shafts 405 may be one or more, and the connecting shafts 405 can be connected to any position on the bearing 403 as long as they can stabilize the bearing 403 and firmly connect it to the main body 10. The advantage of installing the auxiliary wheel 40 is that, as shown in Figure 3c, it allows the main body 10, which has only one drive wheel 20, to maintain balance in the simplest way, and because the ball wheel 401 of the auxiliary wheel 40 is fitted into the bearing 403, the ball wheel 401 can rotate freely 360 degrees without restriction. Therefore, regardless of the rotation angle of the drive wheel 20 or the direction of movement, the ball wheel 401 can rotate in cooperation with it.

[0023] Figure 4a is a schematic diagram illustrating the structure of an airwheel vehicle in a top view according to another embodiment of the present invention, and Figure 4b is a schematic diagram illustrating the structure of an airwheel vehicle in a side view according to another embodiment of the present invention. Referring to Figures 4a to 4b, in another embodiment of the present invention, the airwheel vehicle further includes a plurality of auxiliary wheels 40, each auxiliary wheel 40 comprising a ball wheel 401 and a bearing 403, the ball wheel 401 being fitted into the bearing 403, the bearing 403 being connected to the bottom of the main body 10 by a connecting shaft 405, and each auxiliary wheel 40 being installed opposite the drive wheel 20. In detail, the airwheel vehicle in this embodiment is installed to have the structure of a general car, with four auxiliary wheels 40 installed at the four corners of the bottom of the main body 10 to facilitate the running and horizontal movement of the airwheel vehicle. In other embodiments of the present invention, the number of auxiliary wheels 40 can be adjusted according to the actual need, for example, two, three, four, or four or more.

[0024] On the other hand, in an airwheel vehicle equipped with multiple auxiliary wheels 40, as shown in Figure 4b, when the drive wheel 20 attempts to rotate, the main body 10 is supported by the auxiliary wheels 40 on the ground, and then the computer device 30 can control the control shaft 201 to raise the drive wheel 20 so that it floats in the air. After the drive wheel 20 is floating in the air, the computer device 30 can control the control shaft 201 to rotate. This method of operation has the advantage that the drive wheel 20 does not come into contact with the ground when it rotates, and the energy required for the rotation of the drive wheel 20 can be reduced. In other embodiments, the control shaft 201 may be selectively electrically connected to a lifting mechanism (not shown), and it should be recognized that it is convenient for the computer device 30 to control the control shaft 201 to raise it.
