[0031] In order to enable those skilled in the art to better understand the technical solutions in this application, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0032] It should be noted that when an element is referred to as being "disposed on" another element, it may be directly on the other element or there may be an element centered thereon. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an element centered thereon. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only embodiments.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0034] like Figure 1As shown, an embodiment of the present application provides a power wheel, including: a driving bevel gear 3, which is arranged at the output end of the driving motor 1; a driven bevel gear 4, one end face of which is fixedly connected to the side of the hub 8, and the driven bevel gear 4 is coaxial with the hub 8; the driven bevel gear 4 and the driving bevel gear 3 are engaged with each other; and a fixing member group, which is used to fix the driving motor 1 and the rotating shaft 6.

[0035] To achieve the basic functions of the power wheel, the floor scrubber in the embodiment of the present application may also include other necessary modules or components. It should be noted that the other necessary modules or components included in the floor scrubber can be of any suitable existing structure. To clearly and concisely illustrate the technical solution provided by this application, the above-mentioned part will not be repeated here, and the drawings in the specification have been simplified accordingly. However, it should be understood that the scope of this application is not limited by this.

[0036] In this embodiment, the driving bevel gear 3 is a pinion relative to the driven bevel gear 4, and the driving bevel gear 3 and the driven bevel gear 4 mesh with each other at a 90° angle. The driving bevel gear 3 can mesh with any position of the driven bevel gear 4 within a circle. Preferably, the driving bevel gear 3 meshes with the highest point of the driven bevel gear 4.

[0037] In this embodiment, the driving bevel gear 3 is disposed at the output end of the drive motor 1. The driving bevel gear 3 is disposed at the output shaft end of the drive motor 1. The drive motor 1 provides output shaft speed, driving the driving bevel gear 3 to rotate. Of course, the output end of the drive motor 1 can be synchronized with the motor, or it can be driven by other gears, which is not specifically limited here.

[0038] In this embodiment, one end face of the driven bevel gear 4 is fixedly connected to the side of the wheel hub 8. Specifically, the end face of the driven bevel gear 4 may be provided with a spiral hole that mates with the side of the wheel hub 8. The driven bevel gear 4 is coaxial with the wheel hub 8, and after being fixedly connected to the wheel hub 8, the driven bevel gear 4 and the wheel hub 8 can achieve synchronous rotation. The outer diameter of the driven bevel gear 4 can be smaller than the inner diameter of the wheel hub 8, so that the driven bevel gear 4 can be fixedly mounted inside the wheel hub 8. Of course, the size relationship between the outer diameter of the driven bevel gear 4 and the inner diameter of the wheel hub 8 can also be in other forms, which will not be detailed here.

[0039] In this embodiment, the fixing assembly is used to secure the drive motor 1 and the rotating shaft 6. The rotating shaft 6 is the rotating shaft 6 of the power wheel. It should be noted that since the driven bevel gear 4 rotates coaxially and synchronously, the rotating shaft 6 does not necessarily mean that it is in contact with the wheel hub 8. The rotating shaft 6 can also be the rotating shaft of the driven bevel gear 4. In this embodiment, the fixing assembly is used to secure the drive motor 1 and the rotating shaft 6 to prevent other components from rotating with the driven bevel gear 4 and the wheel hub 8.

[0040] See also Figures 1 to 6 . In an implementation scenario of a power wheel driven by a wheel-side motor, the drive motor 1 is fixed on the motor bracket 2, and the active bevel gear 3 is fixed on the drive motor 1. The motor bracket 2 is sleeved on the rotating shaft 6, and the bracket fixing plate 5 presses the motor bracket 2 for fixing. The bearing 7 is pressed into the wheel hub 8, and the driven bevel gear 4 is installed on the wheel hub 8. The rotating shaft 6 is pressed into the inner ring of the bearing 7, and the rotating shaft fixing plate 9 is installed on the rotating shaft 6 for fixing. In the motion mode, the motor bracket 2 is fixed, the drive motor 1 drives the active bevel gear 3 to rotate, and the active bevel gear 3 drives the driven bevel gear 4 to move. The wheel hub 8 rotates around the bearing 7 to realize power drive.

[0041] In one embodiment, the fixing component group includes at least: a motor bracket 2 and a rotating shaft fixing plate 9 , wherein the motor bracket 2 is sleeved and fixed on one end of the rotating shaft 6 , and the rotating shaft fixing plate 9 is fixed on the other end of the rotating shaft 6 .

[0042] In this embodiment, the rotating shaft fixing plate 9 can serve as a limiting device for the wheel hub 8 to prevent the wheel hub 8 or the driven bevel gear 4 from moving axially along the rotating shaft 6 .

[0043] In one embodiment, the motor bracket 2 is located between the drive motor 1 and the driven bevel gear 4 , and the fixing component group includes at least: a bracket fixing plate 5 , the bracket fixing plate 5 is located between the motor bracket 2 and the drive motor 1 and is used to press the motor bracket 2 .

[0044] In this embodiment, the motor bracket 2 is sleeved and fixed on one end of the rotating shaft 6 , and the bracket fixing plate 5 can press and fix the electrode bracket, thereby improving the stability of the motor bracket 2 .

[0045] In one embodiment, the rotating shaft 6 is sleeved on the inner ring of the bearing 7 , and the outer ring of the bearing 7 cooperates with the wheel hub 8 .

[0046] In one embodiment, the rotating shaft 6 is sleeved on the inner ring of the bearing 7 , and the outer ring of the bearing 7 cooperates with the driven bevel gear 4 .

[0047] In one embodiment, the driven bevel gear 4 is bolted to the side of the wheel hub 8, and the outer diameter of the driven bevel gear 4 is smaller than the inner diameter of the wheel hub 8. This embodiment provides a common and practical fit between the driven bevel gear 4 and the wheel hub 8.

[0048] See also Figure 3 In one embodiment, the number of the bolts is 6 and they are arranged in a circular array.

[0049] In one embodiment, the motor bracket 2 is composed of four bracket plates connected end to end, and the bracket plates are respectively a first bracket plate, a second bracket plate, a third bracket plate, and a fourth bracket plate. The adjacent bracket plates are perpendicular to each other. The first bracket plate is perpendicular to the rotating shaft 6. The second bracket plate is parallel to the top surface of the drive motor 1 and is fixedly connected to the top of the drive motor 1. The output shaft of the drive motor 1 passes through the second bracket plate.

[0050] In this embodiment, the first bracket plate is perpendicular to the rotating shaft 6 and parallel to the end face of the driven bevel gear 4. The second bracket plate is parallel to the top face of the drive motor 1 and is fixedly connected to the top face of the drive motor 1. This structure can further fix the drive motor 1. In this embodiment, the third bracket plate can protect the side of the power wheel. The third bracket plate and the fourth bracket plate can be used to connect the non-rotating parts of the power wheel to the outside world to achieve the installation of the power wheel.

[0051] In one embodiment, the driving bevel gear 3 is engaged with the highest point of the driven bevel gear 4. The installation method in which the driving bevel gear 3 is engaged with the highest point of the driven bevel gear 4 is more applicable and convenient for the application of the power wheel.

[0052] An embodiment of the present application further provides a movable device, comprising: a chassis of the movable device is provided with a power wheel as described in any one of the above items.

[0053] The movable device may be a unicycle, a two-wheeled vehicle, a three-wheeled vehicle, a four-wheeled vehicle, etc. The movable device may also be a movable robot, the chassis of which is provided with the power wheels.

[0054] In the present embodiment, the control module can be implemented in any appropriate manner. Specifically, for example, the control module can take the form of a microprocessor or processor and a computer-readable medium storing a computer-readable program code (such as software or firmware) that can be executed by the microprocessor or processor, a logic gate, a switch, an application-specific integrated circuit (ASIC), a programmable logic controller (PLC), and an embedded microcontroller unit (MCU). Examples of the above modules include, but are not limited to, the following microcontroller units: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320. Those skilled in the art will also know that, in addition to implementing the functions of the control module in a purely computer-readable program code manner, it is entirely possible to implement the same functions of the control unit in the form of logic gates, switches, application-specific integrated circuits, programmable logic controllers, and embedded microcontroller units by logically programming the method steps.

[0055] It should be noted that, in the description of this application, the terms "first," "second," etc., are used solely for descriptive purposes and to distinguish similar objects. There is no order of precedence between the two, nor should they be understood to indicate or imply relative importance. Furthermore, in the description of this application, unless otherwise specified, "plurality" means two or more.

[0056] Any numerical value cited herein includes all values ​​of the lower and upper values ​​in increments of one unit from the lower limit to the upper limit, provided that there is an interval of at least two units between any lower value and any higher value. For example, if the value of the quantity of a component or a process variable (e.g., temperature, pressure, time, etc.) is set forth as being from 1 to 90, preferably from 21 to 80, more preferably from 30 to 70, it is intended to illustrate that values ​​such as 15 to 85, 22 to 68, 43 to 51, 30 to 32 are also explicitly enumerated in this specification. For values ​​less than 1, one unit is appropriately considered to be 0.0001, 0.001, 0.01, 0.1. These are merely examples intended to be clearly expressed, and it is considered that all possible combinations of the numerical values ​​enumerated between the minimum and maximum values ​​are explicitly set forth in this specification in a similar manner.

[0057] Unless otherwise indicated, all ranges include the endpoints and all numbers between the endpoints. When used with a range, "about" or "approximately" applies to both endpoints of the range. Thus, "about 20 to 30" is intended to cover "about 20 to about 30," including at least the specified endpoints.

[0058] It should be understood that the above description is for illustrative purposes only and is not intended to be limiting. Many embodiments and many applications beyond the examples provided will be apparent to those skilled in the art upon reading the above description.
