The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] Figure 1 is a schematic diagram of a wing-spanning steering device 1000 on a driving wheel 2000 according to an embodiment of the present application, Figure 2 It is a schematic diagram of a steering wheel 1200 and a wing-spanning driving wheel 1400 according to an embodiment of the present application.

[0021] refer to Figure 1 and Figure 2 The present application proposes a wing-spreading steering device 1000 on a driving wheel 2000, and the wing-spreading steering device 1000 comprises: a wing-spreading 1100, a steering wheel 1200, a steering drive seat 1300, and a wing-spreading driving wheel 1400. The wing-spreading 1100 has a notch to accommodate the steering wheel 1200 to reduce the height of the driving wheel 2000. Optionally, the shape and size of the notch of the wing-spreading 1100 can be adjusted according to the shape and size of the steering wheel 1200.

[0022] refer to Figure 2 The steering wheel 1200 is disposed in the notch of the wing 1100 and is rotatably connected to the wing 1100 via a steering wheel pivot 1210 along the axial direction of the steering wheel 1200. The steering drive seat 1300 is fixedly connected to the steering wheel pivot 1210. The wing drive wheel 1400 is rotatably connected to the steering drive seat 1300 via a pivot 1410 perpendicular to the steering wheel pivot 1210.

[0023] According to the embodiment of the present application, when the steering wheel 1200 performs a rotational action, since the steering wheel pivot 1210 is in a rigid connection state with the steering wheel 1200, the steering wheel pivot 1210 also rotates in coordination therewith. In addition, the rotation of the steering wheel pivot 1210 further drives the steering drive seat 1300 to perform a corresponding rotational movement around the axis of the steering wheel pivot 1210. Since the wing-spreading driving wheel 1400 is connected to the steering drive seat 1300 via the pivot 1410 which is perpendicular to the steering wheel pivot 1210, the rotation of the steering drive seat 1300 can drive the rotation of the wing-spreading driving wheel 1400, and finally change the displacement direction of the driving wheel 2000.

[0024] refer to Figure 2 The surface of the wing drive wheel 1400 is provided with grooves. The grooves can increase the friction force, increase the contact area between the wing drive wheel 1400 and the ground, and prevent the drive wheel 2000 from slipping. In addition, the depth, width, and direction of the grooves of the wing drive wheel 1400 can be adaptively changed according to the actual terrain. For example, the depth and width of the grooves can be increased in rough terrain.

[0025] According to the present application, the surface of the wing-spreading driving wheel 1400 can be made of materials such as rubber and polyurethane, so that the surface of the wing-spreading driving wheel 1400 can effectively absorb and alleviate the impact and vibration generated when the driving wheel passes through uneven or bumpy ground.

[0026] refer to Figure 2 The steering drive seat 1300 further includes: a horizontal fixing seat 1310 perpendicular to the steering wheel pivot 1210 and a vertical fixing seat 1320 vertically fixedly connected to the horizontal fixing seat 1310. Specifically, the horizontal fixing seat 1310 is fixedly connected to the steering wheel 1200, and the vertical fixing seat 1320 is rotationally connected to the wing drive wheel 1400. Therefore, the steering drive seat 1300 can realize the transmission of the motion direction, ensuring that the rotation of the steering wheel 1200 can be transmitted to the wing drive wheel 1400, thereby realizing the direction control of the drive wheel 2000.

[0027] refer to Figure 2 , the steering wheel pivot 1210 is mounted on a gasket 1500 fixedly connected to the wing 1100, and the surface of the gasket 1500 is parallel to the surface of the steering wheel 1200. Specifically, when the steering wheel 1200 is rotating, the steering wheel 1200 is in a rotating state relative to the wing 1100, and the gasket 1500 installed between the steering wheel 1200 and the wing 1100 can reduce the friction between the two and thus reduce the loss. In addition, when the driving wheel 2000 passes through a bumpy road, the gasket 1500 can also play a shock-absorbing role in alleviating vibrations, so as to protect the steering wheel 1200 and prevent the steering accuracy of the steering wheel 1200 from being greatly affected.

[0028] Figure 3 It is a cross-sectional schematic diagram of the steering wheel 1200 and the wing-spanning driving wheel 1400 according to the embodiment of the present application.

[0029] refer to Figure 3 The wing-spreading steering device 1000 also includes a steering wheel bearing 1600. One side 1610 of the steering wheel bearing is fixedly connected to the steering wheel pivot 1210, and the other side 1620 of the steering wheel bearing is fixedly connected to the horizontal fixing seat 1310. Specifically, the steering wheel bearing 1600 can support the steering wheel pivot 1210, while reducing the friction loss between the steering wheel pivot 1210 and the horizontal fixing seat 1310. In addition, both sides of the steering wheel bearing 1600 are perpendicular to the steering wheel pivot 1210, which can stabilize the axis and withstand the axial force, ensuring that the steering wheel 1200 can always rotate with the axis of the steering wheel pivot 1210 as the center of the circle. Optionally, the steering wheel bearing 1600 can be a thrust bearing. Optionally, the steering wheel pivot 1210 and the horizontal fixing seat 1310 can be fixed as a whole to replace the steering wheel bearing 1600.

[0030] Figure 4 It is a schematic diagram of a driving wheel 2000 equipped with a wing-spanning steering device 1000 according to an embodiment of the present application.

[0031] refer to Figure 4 According to one embodiment of the present invention, a driving wheel 2000 equipped with a wing-spreading steering device 1000 according to an embodiment of the present application can be applied to a two-wheeled robot, and is particularly suitable for narrow spaces such as flues. Specifically, a pair of wing-spreading steering devices 1000 can be configured on one side of the driving wheel 2000, and the two-wheeled robot has two driving wheels 2000, so the two-wheeled robot with two pairs of wing-spreading steering devices 1000 will be more stable during operation and can perform in-situ steering operations. In addition, the wing-spreading steering devices 1000 on the same side can adjust the opening and closing angles between the wings 1100 through relative movement, thereby achieving the adjustment of the height of the two-wheeled robot. Specifically, when the wing-spreading driving wheel 1400 moves to both sides, the larger the opening and closing angles between the wings 1100, the lower the height of the two-wheeled robot. When the wing-spreading driving wheel 1400 gathers toward the middle, the smaller the opening and closing angles between the wings 1100, the higher the height of the two-wheeled robot. On the one hand, this function is particularly suitable for wading roads to prevent water from entering the inside of the two-wheeled robot and causing internal equipment failures. On the other hand, by adjusting the height, the two-wheeled robot can adapt to spaces with different height requirements, thereby expanding its application range and movement flexibility. After the two-wheeled robot relies on the wing-spreading steering device 1000 to provide displacement and steering functions, the original driving device of the two-wheeled robot can be equipped with cleaning devices and other equipment suitable for different functional scenarios.

[0032] Taking flue cleaning as an example, the flue cleaning device can be installed on the driving wheel 2000 along the circumferential direction of the driving wheel 2000. The wing-spreading steering device 1000 is used to adjust the height and travel direction of the two-wheeled robot, that is, the movement direction of the wing-spreading driving wheel 1400 is controlled by the rotation of the steering wheel 1200, and the height of the two-wheeled robot is adjusted by the relative movement of the wing-spreading driving wheel 1400. The two-wheeled robot adjusted to a suitable height travels along the flue direction, and the flue cleaning device moves in the circumferential direction to remove the residue in the flue, so that the travel and cleaning functions of the two-wheeled robot are carried out simultaneously.

[0033] Although the embodiment of the present application only gives an example of a single wing-spanning steering device 1000, it is easy for a person skilled in the art to understand that the wing-spanning steering device 1000 provided in the present application can be used to drive single-wheel, two-wheel, three-wheel, four-wheel, six-wheel or other wheeled robots, and solve the same or similar technical problems.

[0034] The above description is only an implementation method of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of protection involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the technical concept. For example, the above features are replaced with the technical features with similar functions disclosed in this application (but not limited to) by each other.
