Among them, the second mounting member is rotatably connected to the first mounting member, and the steering drive member drives the second mounting member and the traveling mechanism to turn by driving the rotating member to rotate, and the rotating member is located in the mounting cavity to prevent environmental impurities from interfering with the operation of the rotating member, ensuring smooth steering of the steering wheel device, and solving the technical problem that the existing steering wheel device is prone to steering difficulties in dusty working scenes.

At this time, it is necessary to forcibly control the steering wheel to recover in order to detect its positioning accuracy and reset it after detection. However, the current steering wheel recovery is often manually adjusted, which is not only time-consuming and labor-intensive, but also difficult to control the accuracy, which is inconvenient.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] See also Figure 1-Figure 4 A self-driving electric steering wheel comprises a steering wheel bracket 1, a mobile motor 2 installed on one side of the steering wheel bracket 1 and a mobile wheel 10 installed inside the steering wheel bracket 1, a bottom plate 3 is fixedly connected to the side of the steering wheel bracket 1 away from the mobile wheel 10, a connecting plate 4 is fixedly connected to the side of the bottom plate 3 away from the steering wheel bracket 1, a rotating assembly is connected to the side of the bottom plate 3 away from the steering wheel bracket 1, a steering mechanism is connected to the side of the connecting plate 4 away from the steering wheel bracket 1, the steering mechanism is matched with the rotating assembly, a positioning sensor 8 is fixedly connected to the side of the bottom plate 3 close to the steering wheel bracket 1, a positioning plate 14 is connected to the side of the bottom plate 3 close to the steering wheel bracket 1, the upper surface of the positioning plate 14 is connected to the rotating assembly, and the positioning sensor 8 is matched with the positioning plate 14.

[0023] The automatic electric steering wheel in the utility model is similar to the existing steering wheel structure, such as a steering wheel device, chassis and mobile robot disclosed in the patent with publication number CN218055343U. Figures 1 to 4As shown, before the automatic electric steering wheel in the utility model is used, the rotating assembly is first connected and fixed to the bottom surface of an external robot or vehicle and other equipment. After the steering wheel is used for a period of time, when the steering wheel bracket 1 and the moving wheel 10 have a certain tilt error relative to the robot or vehicle and other equipment above, in order to avoid affecting normal walking and steering, it is necessary to perform positioning detection on them. At this time, it is only necessary to drive the steering wheel bracket 1, the moving motor 2 and the moving wheel 10 and other components to rotate together through the steering mechanism. When the steering wheel bracket 1 rotates, the bottom plate 3, the connecting plate 4 and the steering mechanism located above the steering wheel bracket 1 will rotate together. During the rotation, because the positioning sensor 8 is installed on the bottom plate 3, the positioning sensor 8 will also rotate together. Because the positioning plate 14 is installed together with the rotating assembly, it is in a fixed position relative to the robot or vehicle and other equipment. Therefore, after the positioning sensor 8 rotates to a position aligned with the positioning plate 14, the positioning sensor 8 transmits an electrical signal to the external processor, and then sets this point as the base point through the controller, so that the positioning adjustment can be automatically completed, which is convenient and fast, and the accuracy is more accurate.

[0024] Special mention should be made here:

[0025] 1. The positioning sensor 8 can be turned off during normal steering use and turned on only when positioning and locating; it can also be turned on all the time, so that the base point can be recorded at all times during the steering process, thereby eliminating the subsequent locating step, and the specifics are not limited;

[0026] 2. External processors and controllers are common technologies in existing application scenarios, so they are not described in detail.

[0027] Please refer to Figure 1-Figure 3 The steering mechanism includes a steering motor 5 and a main gear 6. The outer wall of the steering motor 5 is fixedly connected to the bottom surface of the connecting plate 4. The output shaft of the steering motor 5 passes through the connecting plate 4 and is fixedly connected to the main gear 6. The main gear 6 is connected to the rotating assembly.

[0028] More specifically, when normally controlling the steering of a robot or vehicle or other equipment, the external controller turns on the steering motor 5. After the steering motor 5 is started, the output shaft drives the main gear 6 to rotate, which can then drive the entire connecting plate 4, the base plate 3, the steering wheel bracket 1, the moving motor 2 and the moving wheel 10 to rotate together, thereby achieving the purpose of steering.

[0029] Please refer to Figure 1-Figure 3 The rotating assembly includes a slave gear 7 and a bearing 11. One side of the bearing 11 is fixedly connected to the upper surface of the bottom plate 3. The slave gear 7 is sleeved and rotatably connected to the outer wall of the bearing 11. The outer wall of the slave gear 7 is meshed with the outer wall of the main gear 6. A plurality of mounting holes 701 are formed through the upper surface of the slave gear 7.

[0030] First of all, it should be noted that: the slave gear 7 is connected to an external robot or vehicle or other equipment through bolts under the action of a plurality of mounting holes 701, thereby limiting the position of the slave gear 7 relative to the robot or vehicle or other equipment to maintain a fixed position.

[0031] More specifically, when the main gear 6 keeps rotating under the drive of the steering motor 5, the main gear 6 and the slave gear 7 rotate relatively due to meshing, and because the slave gear 7 is fixedly connected to the robot or vehicle and other equipment, the main gear 6 will drive the steering motor 5 and the connecting plate 4 below to rotate together. Because the slave gear 7 has a bearing 11 inside, the base plate 3 and the slave gear 7 will not separate while ensuring that the slave gear 7 and the base plate 3 are in relative rotation.

[0032] Please refer to Figure 3 , connecting rods 13 are fixedly connected to both ends of the upper surface of the positioning plate 14, and the outer walls of the two connecting rods 13 are respectively fixedly connected to the inner walls of two mounting holes 701. By providing two connecting rods 13, firstly, the connectivity between the positioning plate 14 and the slave gear 7 can be increased; secondly, the position of the positioning plate 14 on the bottom surface of the slave gear 7 can be limited, making it less likely to be misplaced or tilted, thereby making the positioning accuracy higher.

[0033] Please refer to Figure 3 The positioning plate 14 is an arc surface, and the arc surface is exactly half of the bottom plate 3. The purpose of this arrangement is that when positioning and aligning, no matter which end of the positioning sensor 8 is aligned with the positioning plate 14, positioning and aligning can be performed, making the aligning speed faster.

[0034] Please refer to Figure 2 and Figure 3 A mounting plate 9 is fixedly connected to one side of the steering wheel bracket 1, and a supporting bolt 12 is connected to the inner wall of the other side of the steering wheel bracket 1. The screw of the supporting bolt 12 passes through the inner wall of the moving wheel 10 and is threadedly connected to the inner wall of the mounting plate 9.

[0035] More specifically, the moving wheel 10 will wear out faster than other parts due to long-term walking and turning, and therefore needs to be frequently repaired and replaced. However, the moving wheel 10 and the steering wheel bracket 1 are mostly non-detachable, or the entire steering wheel bracket 1 needs to be removed before the moving wheel 10 can be removed. At this time, by providing a mounting plate 9 and a support bolt 12, the central axis of the moving wheel 10 is placed on the support bolt 12, and when the moving wheel 10 needs to be removed for repair and replacement, it can be more convenient and quick.

[0036] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art may still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
