Description

Technical Field

[0001] This utility model relates to the field of wheel technology, and in particular to a deformable wheel. Background Technology

[0002] Current all-terrain vehicles are typically equipped with four wheels, all of which are regularly round for ease of movement. However, in situations involving geological disasters, rescue operations, and expeditions, the terrain is often extremely complex, with unstructured roads. Conventional wheels often struggle to navigate these conditions, primarily due to the slippery, rugged, and steep nature of unstructured terrain. Conventional wheels have a small contact area with the ground or a low coefficient of friction, making them prone to slipping. Yet, in conventional terrain, rapid movement is required, making traditional round wheels insufficient to meet the diverse needs.

[0003] Therefore, there is an urgent need to develop a deformable wheel that can travel quickly on flat paths and maintain stable driving on unstructured terrain. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a deformable wheel.

[0005] The objective of this utility model can be achieved through the following technical solutions: A deformable wheel includes an electrical rotary joint and a central shaft connected to one end thereto; spokes are fixed to both ends of the central shaft by connecting keys; the two spokes have identical structures and are arranged symmetrically; multiple rotatable rotating plates are arranged between the two spokes; a slip ring is fitted on the central shaft; a motor is also fixed on the central shaft; the motor is connected to a lead screw; the lead screw passes through the slip ring and is rotatably connected to the spokes; the lead screw is threadedly connected to the slip ring; multiple support rods are rotatably connected to the slip ring, and each support rod is rotatably connected to the bottom of a corresponding rotating plate.

[0006] Furthermore, the spokes are provided with eight rotating plate mounting holes; there are eight rotating plates, which are connected to the rotating plate mounting holes.

[0007] Furthermore, the support rod and the rotating plate, as well as the support rod and the slip ring, are all connected by ball joints for rotation.

[0008] Furthermore, the rotating plate is a rotating plate with rounded corners on its edges.

[0009] Furthermore, a central hole is provided on the central shaft; the motor is fixed above the central hole of the central shaft; the motor is electrically connected to the vehicle via a wire; the wire is introduced from the electrical rotary joint into the central hole of the central shaft and connected to the motor.

[0010] Compared with the prior art, the present invention has the following advantages: (1) This utility model uses a closed-chain spatial linkage structure composed of a slip ring, a support rod, a rotating plate, and wheel spokes. The slip ring is moved by the rotation of the lead screw driven by the motor, and the rotating plate is opened and closed by the support rod. This allows the wheel to switch between circular and hook-claw shapes. The circular shape allows for rapid propulsion in conventional terrain, while the hook-claw shape provides traction by penetrating the ground or hooking onto objects. The structure is simple, efficient, and applicable to a wide range of terrains. Furthermore, the hook-claw shape can adapt to the impact of rapid changes in terrain, making it suitable for use in most unstructured terrains.

[0011] (2) The wheel of this utility model can also actively control the wheel diameter by controlling the movement distance of the slip ring according to the road conditions, and has a wider range of applications. Attached Figure Description

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0019] Furthermore, terms such as "horizontal" and "vertical" do not imply that components must be absolutely horizontal or suspended, but rather that they can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but can be slightly tilted. Example

[0020] like Figure 1As shown, a deformable wheel includes an electrical rotary joint 1, spokes 2, a support rod 3, a rotating plate 4, a slip ring 5, a lead screw 6, a connecting key 7, a central shaft 8, a motor 9, and rotating plate mounting holes 10. One end of the electrical rotary joint 1 is connected to one end of the central shaft 8. Both ends of the central shaft 8 are fixed to spokes 2 via connecting keys 7. The two spokes 2 have identical structures and are symmetrically arranged. Multiple rotatable rotating plates 4 are arranged between the two spokes 2. Eight rotating plate mounting holes 10 are provided on each spoke 2. The eight rotating plates 4 are correspondingly connected to the rotating plate mounting holes 10. A slip ring 5 is fitted onto the central shaft 8. A motor 9 is also fixed on the shaft 8; a central hole is provided on the central shaft 8; the motor 9 is fixed above the central hole of the central shaft 8, and an electric wire is introduced into the central hole of the central shaft 8 from the electrical rotary joint 1 and connected to the motor 9, with the other end of the wire connected to the vehicle; a lead screw 6 is connected to the motor 9; the lead screw 6 passes through the slip ring 5 and is rotatably connected to the wheel spoke 2; the lead screw 6 is threadedly connected to the slip ring 5; multiple support rods 3 are rotatably connected to the slip ring 5, and each support rod 3 is rotatably connected to the bottom of the corresponding rotating plate 4; the support rods 3 and the rotating plate 4, as well as the support rods 3 and the slip ring 5, are all connected by ball joints for rotation; Figure 6 As shown, the slip ring 5, support rod 3, rotating plate 4, and wheel spokes 2 together form a closed-chain spatial linkage structure. The rotating plate 4 rotates with the wheel spokes 2, the rotating plate 4 rotates spherically with the support rod 3, the support rod 3 rotates spherically with the slip ring 5, the slip ring 5 moves laterally with the central shaft 8, and the central shaft 8 is fixedly connected to the wheel spokes. The rotation of the rotating plate 4 is controlled by the movement of the slip ring 5, realizing the switching between circular and hook-shaped forms, which is used to control the wheel to change between circular and hook-shaped deformation.

[0021] The specific deformation principle is as follows: When the motor 9 receives the deformation signal, it drives the lead screw 6 to rotate clockwise or counterclockwise. The lead screw 6 rotates, thereby driving the slip ring 5 to move left or right on the central shaft 8. When the slip ring 5 moves, it drives the 8 evenly distributed support rods 3 to move through the connected ball joint. When the support rods 3 move, they push the 8 equally distributed rotating plates 4 to rotate. When the 8 rotating plates 4 contract or expand at the same time, the wheel shape changes between a circle and a hook shape. When the rotating plate 4 contracts, it deforms into a regular circular shape. When the rotating plate 4 expands, it deforms into a hook shape.

[0022] like Figure 2 As shown, in the normal circular state, the central shaft 8, connecting key 7, and spokes 2 form the frame of the wheel. At this time, the position of the rotating plate 4 coincides with the outer diameter of the spokes 2, and the support rod 3 and slip ring 5 are fixed, forming a circular wheel shape.

[0023] like Figure 3As shown, when the slip ring 5 moves, it drives the support rod 3 to move, lifting the rotating plate 4. After the rotating plate 4 rotates, the overall diameter of the wheel increases, the rotating plate 4 unfolds, and the edge of the rotating plate 4 directly contacts the ground, entering a claw-like state, i.e., a hook-claw shape.

[0024] Depending on the road conditions, different widths may be required. In this case, the wheel diameter can be actively controlled by controlling the movement distance of the slip ring 5, making it more applicable.

[0025] like Figure 4 and 5 As shown, the edges of the rotating plate 4 are rounded to make it easier to embed into soft terrain and hook onto objects. Furthermore, to extend the travel of the rotating plate 4 within a limited space, the location of the ball socket on the rotating plate 4 is offset.

[0026] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
