[0034] In the description, claims, and the above-mentioned drawings of this application, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprise" and "have" and any variations thereof are intended to cover non-exclusive inclusion. For example, a component or device that includes one or more components is not limited to the one or more components listed, but optionally also includes one or more components that are not listed but are inherent in the product exemplified, or one or more components that it should have based on the described functions.

[0035] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 which is a schematic diagram of an autonomous mobile working device provided for an embodiment of this application; Figure 2 is Figure 1 a three-dimensional exploded schematic diagram of the autonomous mobile working device in Figure 3 a cross-sectional schematic diagram of an autonomous mobile working device provided for another embodiment. The autonomous mobile working device 1 includes a body 100, a battery assembly 600, a first electrode assembly 310, and a working unit 320. In addition, the autonomous mobile working device 1 further includes a circuit board 210 and two driving wheels 220. The circuit board 210 is disposed inside the body 100, and two driving wheels 220 are disposed at intervals at the rear end of the body 100. The battery assembly 600 is disposed between the two driving wheels 220 and is electrically connected to the circuit board 210. The first electrode assembly 310 is disposed on both sides of the rear end of the body 100, the first electrode assembly 310 is electrically connected to the circuit board 210 and is exposed outside the body 100, and the first electrode assembly 310 is used to charge the battery assembly 600. The working unit 320 is disposed at the bottom of the body 100 and is used to perform a preset working task.

[0036] The autonomous mobile working device 1 can be, but is not limited to, a lawn mower or a sweeper, etc., which are devices that can move by themselves. In the schematic diagram of this embodiment, the autonomous mobile working device 1 is taken as an example of a lawn mower for illustration. It can be understood that it should not be construed as a limitation on the autonomous mobile working device 1 provided by the embodiments of this application.

[0037] The body 100 is the frame of the autonomous mobile working device 1, or is also called a housing. The body 100 is generally used to house the circuit board 210 of the autonomous mobile working device 1, install the driving wheels 220, and the working unit 320, etc.

[0038] The battery assembly 600 is used to store electrical energy to provide the electrical energy required for the operation of the self - moving working device 1. In this embodiment, the battery assembly 600 is a rechargeable battery, and the battery assembly 600 is electrically connected to the first electrode assembly 310 to receive the electrical energy output by the first electrode assembly 310 and store it.

[0039] In this embodiment, the battery assembly 600 is a detachable battery assembly 600 to facilitate the replacement and repair of the battery assembly 600. It can be understood that in other embodiments, the battery assembly 600 can also be a non - detachable battery assembly 600.

[0040] The drive wheels 220 are located at the rear end of the body 100, and the battery assembly 600 is disposed between the drive wheels 220. Therefore, the battery assembly 600 is also located at the rear end of the body 100. The first electrode assembly 310 is provided on both sides of the rear end of the body 100. Therefore, both the first electrode assembly 310 and the battery assembly 600 are located at the rear end of the body 100. In this way, the distance between the first electrode assembly 310 and the battery assembly 600 is relatively close, facilitating the first electrode assembly 310 to charge the battery assembly 600.

[0041] In addition, the first electrode assembly 310 is provided on both sides of the rear end of the body 100. Therefore, when the first electrode assembly 310 cooperates with the second electrode assembly of the charging pile, it can better contact the second electrode assembly of the charging pile, having good contact performance. Furthermore, the self - moving working device 1 can be better charged by the charging pile.

[0042] In one embodiment, a voltage conversion circuit may be provided on the circuit board 210. The circuit board 210 is electrically connected to the first electrode assembly 310 to receive the first voltage transmitted from the first electrode assembly 310. The voltage conversion circuit is used to convert the first voltage into a second voltage to charge the battery pack assembly. Wherein, the voltage value of the second voltage is less than the voltage value of the first voltage. In addition, in one embodiment, a plurality of components are provided on the circuit board 210. The circuit board 210 is electrically connected to the battery assembly 600, and the battery assembly 600 is used to provide the electrical energy required for the components on the circuit board 210 to operate.

[0043] In this embodiment, the drive wheels 220 are mounted on the body 100. The so-called rear end of the body 100 refers to the end located at the rear in the traveling direction when the self-propelled working device 1 travels. Two drive wheels 220 are arranged at intervals at the rear end of the body 100. The drive wheels 220 are used for walking to realize the moving function of the self-propelled working device 1. It can be understood that in this embodiment, the number of wheels in the self-propelled working device 1 is not limited. The wheels of the self-propelled working device 1 may include the two drive wheels 220, or may include or not include other wheels.

[0044] The battery assembly 600 is arranged between the two drive wheels 220. Therefore, the space between the drive wheels 220 can be fully utilized to arrange the battery assembly 600, making the self-propelled working device 1 relatively compact and small in volume. For example, in the related art, the battery assembly 600 of the self-propelled working device 1 is located behind the drive wheels 220. Then, the length of the self-propelled working device 1 in the related art is longer. In the self-propelled working device 1 provided by the embodiment of the present application, the battery assembly 600 is arranged between the two drive wheels 220. Then, the length of the self-propelled working device 1 is shorter, and the self-propelled working device 1 is more compact and can work well in a relatively narrow space.

[0045] The working unit 320 is a component for the self-propelled working device 1 to realize the corresponding working function. For example, when the self-propelled working device 1 is a lawn mower, the working unit 320 can be a cutting knife. When the self-propelled working device 1 is a sweeper, the working unit 320 can be a broom for realizing the sweeping function.

[0046] In summary, for the self-propelled working device 1 provided by the embodiment of the present application, the drive wheels 220 are located at the rear end of the body 100, and the battery assembly 600 is arranged between the drive wheels 220. Therefore, the battery assembly 600 is also located at the rear end of the body 100. The first electrode assembly 310 is arranged on both sides of the rear end of the body 100. Therefore, both the first electrode assembly 310 and the battery assembly 600 are located at the rear end of the body 100. In this way, the distance between the first electrode assembly 310 and the battery assembly 600 is relatively close, facilitating the first electrode assembly 310 to charge the battery assembly 600. In addition, the battery assembly 600 is arranged between the two drive wheels 220. Therefore, the space between the drive wheels 220 can be fully utilized to arrange the battery assembly 600, making the self-propelled working device 1 relatively compact and small in volume, and capable of working well in a relatively narrow space.

[0047] Further, please refer to Figure 3, in an embodiment, the lower end surface 600a of the battery assembly 600 is located above the axle 220a of the two driving wheels 220.

[0048] In this embodiment, the lower end of the battery assembly 600 is located above the axles of the two driving wheels 220, which can make the battery assembly 600 relatively far from the ground. Thus, when there is water on the ground, it can reduce or even avoid the water on the ground from entering the battery assembly 600 and damaging the battery assembly 600.

[0049] Further, please refer to Figure 4 and Figure 5 , Figure 4 is a schematic diagram of a driving wheel provided by an embodiment of the present application; Figure 5 is Figure 4 a three-dimensional exploded schematic diagram of the driving wheel provided in

[0050] The hub 221 can bear the weight of the body 100, and the hub 221 can rotate to drive the body 100 to move forward. The driving motor 222 is used to drive the hub 221 to rotate. The driving motor 222 is arranged inside the hub 221 and the output shaft 2221 of the driving motor 222 extends towards the battery assembly 600 to the outside of the hub 221. In other words, a part of the output shaft 2221 of the driving motor 222 is located inside the hub 221, and another part of the output shaft 2221 of the driving motor 222 is located outside the hub 221, and the other part of the output shaft 2221 is located on the side of the hub 221 facing the battery assembly 600. The output shaft 2221 of the driving motor 222 is connected to the body 100. In this embodiment, the other part of the output shaft 2221 of the driving motor 222 is connected to the body 100.

[0051] In this embodiment, the self - moving working device 1 includes two driving wheels 220, and the two driving wheels 220 are respectively arranged on two opposite sides of the body 100. In other words, one of the two driving wheels 220 is arranged on one side of the body 100, and the other of the two driving wheels 220 is arranged on the opposite side of the body 100. The output shaft 2221 of the driving motor 222 of one of the two driving wheels 220 is connected to the body 100 and is located on the said one side of the body 100; the output shaft 2221 of the driving motor 222 of the other of the two driving wheels 220 is connected to the body 100 and is located on the said other side of the body 100, where the other side and the one side are two opposite sides of the body 100.

[0052] The battery assembly 600 is located between the output shafts 2221 of the two driving motors 222. With such an arrangement of the battery assembly 600, the space between the driving wheels 220 can be fully utilized to arrange the battery assembly 600, making the self - moving working device 1 relatively compact with a small volume, and enabling it to work well in a relatively narrow space.

[0053] Further, please refer to Figure 3 , the self - moving working device 1 further includes a first positioning component 330 for positioning when it executes a preset task. The first positioning component 330 is arranged on the body 100 and is located above the battery assembly 600.

[0054] In this embodiment, the first positioning component 330 can be but is not limited to a Real - Time Kinematic (RTK) positioning component. The first positioning component 330 is arranged on the body 100 and is located above the battery assembly, which can reduce or even avoid the occlusion of the first positioning component 330 by other components in the self - moving working device 1 when using the first positioning component 330 for positioning, thus facilitating the self - moving working device 1 to use the first positioning component 330 for positioning when executing a preset task.

[0055] Further, please continue to refer to Figure 3 , the self - moving working device 1 further includes a second positioning component 340 for positioning when it drives towards a charging pile. The second positioning component 340 is arranged on the body 100 and is located above the battery assembly 600.

[0056] When the battery assembly 600 in the self - moving working device 1 needs to be charged, the self - moving working device 1 drives towards the charging pile to charge the battery assembly 600 in the self - moving working device 1 using the charging pile. The second positioning assembly 340 is used to cooperate with the positioning assembly of the charging pile when the self - moving working device 1 drives towards the charging pile to position the self - moving working device 1. The second positioning assembly 340 can be, but is not limited to, an infrared positioning assembly.

[0057] The second positioning assembly 340 is disposed on the body 100 and above the battery assembly 600, which can reduce or even avoid the occlusion of the second positioning assembly 340 by other components in the self - moving working device 1 when using the second positioning assembly 340 for positioning, thus facilitating the self - moving working device 1 to use the second positioning assembly 340 for positioning when driving towards the charging pile.

[0058] In one embodiment, the self - moving working device 1 only includes the first positioning assembly 330 and does not include the second positioning assembly 340. In another embodiment, the self - moving working device 1 only includes the second positioning assembly 340 and does not include the first positioning assembly 330. In yet another embodiment, the self - moving working device 1 includes the first positioning assembly 330 and also includes the second positioning assembly 340.

[0059] In one embodiment, the first positioning assembly 330 is located above the battery assembly 600, and the first positioning assembly 330 is disposed adjacent to one end of the battery assembly 600 away from the rear end face of the body 100. The second positioning assembly 340 is located above the battery assembly 600, and the second positioning assembly 340 is adjacent to one end of the battery assembly 600 close to the rear end face of the body 100. The above - mentioned arrangement of the first positioning assembly 330 and the second positioning assembly 340 can reduce or even avoid the occlusion of the second positioning assembly 340 by the first positioning assembly 330, thus facilitating the self - moving working device 1 to use the second positioning assembly 340 for positioning when driving towards the charging pile.

[0060] Further, please continue to refer to Figure 2 and Figure 3 , a battery cavity 110 extending along the traveling direction of the self - moving working device 1 is provided at the rear end of the body 100, and the battery assembly 600 is disposed in the battery cavity 110 and electrically connected to the circuit board 210.

[0061] A battery chamber 110 extending along the traveling direction of the self - moving working device 1 is provided at the rear end of the body 100, and the battery assembly 600 is disposed in the battery chamber 110. Therefore, it is convenient for the installation of the battery assembly 600. When the battery assembly 600 is a detachable battery assembly 600, a battery chamber 110 extending along the traveling direction of the self - moving working device 1 is provided at the rear end of the body 100, and the battery assembly 600 is disposed in the battery chamber 110, which is convenient for the installation and disassembly of the battery assembly 600.

[0062] Further, the battery chamber 110 has an opening 110a, and one end of the battery chamber 110 close to the opening 110a is higher than the end of the battery chamber 110 away from the opening 110a.

[0063] In one embodiment, the battery chamber 110 is inclined. For example, when the self - moving working device 1 is disposed on a flat ground with the same altitude, the distance from the battery chamber 110 to the ground gradually decreases from the end adjacent to the opening 110a towards the end away from the opening 110a. In another embodiment, the battery chamber 110 includes a first sub - chamber 111 and a second sub - chamber 112. The first sub - chamber 111 faces away from the opening 110a, and the second sub - chamber 112 has the opening 110a. When the self - moving working device 1 is disposed on a flat ground with the same altitude, the distance from the first sub - chamber 111 to the ground is a first distance, and the distance from the second sub - chamber 112 to the ground is a second distance, and the second distance is less than the first distance.

[0064] In one embodiment, the height difference H between the end of the battery chamber 110 having the opening 110a and the end of the battery chamber 110 away from the opening 110a satisfies: 1 cm ≤ H ≤ 5 cm. For example, the height difference H can be, but is not limited to, 1 cm, or 2 cm, or 3 cm, or 4 cm, or 5 cm. The height difference H between the end of the battery chamber 110 having the opening 110a and the end of the battery chamber 110 away from the opening 110a satisfies: 1 cm ≤ H ≤ 5 cm. On the one hand, it can make the battery assembly 600 not easily fall off from the opening 110a of the battery chamber 110, and on the other hand, it is convenient for the battery assembly 600 to be disassembled from the opening 110a of the battery chamber 110.

[0065] In summary, one end of the battery chamber 110 close to the opening 110a is higher than the end of the battery chamber 110 away from the opening 110a. Therefore, to a certain extent, it can reduce or even prevent the battery assembly 600 from falling off from the opening 110a of the battery chamber 110.

[0066] Further, please refer toFigure 2 and Figure 3 and also Figure 6 , Figure 6 is Figure 3 A schematic diagram of the dimensions of the first sub - cavity and the second sub - cavity in the battery cavity shown in []. The battery cavity 110 includes a first sub - cavity 111 and a second sub - cavity 112. The first sub - cavity 111 faces away from the opening 110a, and the second sub - cavity 112 has the opening 110a. The cross - sectional area of the first sub - cavity 111 is smaller than that of the second sub - cavity 112. The length of the first sub - cavity 111 along the traveling direction is a first length L1, and the length of the second sub - cavity 112 along the traveling direction is a second length L2, and the second length L2 is smaller than the first length L1.

[0067] In this embodiment, the first sub - cavity 111 is the part of the battery cavity 110 that faces away from the opening 110a, and the second sub - cavity 112 has the opening 110a. The cross - sectional area of the first sub - cavity 111 is smaller than that of the second sub - cavity 112. Therefore, when the cross - sectional areas of all parts of the battery assembly 600 are the same or approximately the same, the part of the battery assembly 600 located in the first sub - cavity 111 can be better fixed within the first sub - cavity 111. The cross - sectional area of the second sub - cavity 112 is larger, which facilitates a user to insert a hand or a tool into the second sub - cavity 112 to disassemble and remove the battery assembly 600; or, it is convenient to put the battery assembly 600 into the battery cavity 110 through the second sub - cavity 112.

[0068] The length of the first sub - cavity 111 along the traveling direction is a first length, and the length of the second sub - cavity 112 along the traveling direction is a second length, and the second length is smaller than the first length. Therefore, most of the battery assembly 600 is located in the first sub - cavity 111, that is, the part of the battery assembly 600 that is greater than or equal to one - half is located in the first sub - cavity 111. The remaining part of the battery assembly 600 is less than one - half of the battery assembly 600.

[0069] Most of the battery assembly 600 is located within the first sub-cavity 111, and a small portion of the battery assembly 600 is located within the second sub-cavity 112. The cross-sectional area of the first sub-cavity 111 is smaller than that of the second sub-cavity 112. Therefore, on the one hand, the battery assembly 600 can be better fixed within the first sub-cavity 111 and is not easily removed from the first sub-cavity 111. On the other hand, it also enables the user to easily insert their hand or a tool into the second sub-cavity 112 to remove and take out the battery assembly 600; or, it is convenient to place the battery assembly 600 into the battery cavity 110 through the second sub-cavity 112.

[0070] Further, please refer to Figure 3 , the self-propelled working device 1 further includes a waterproof sealing ring 350. A stepped portion 113 is formed at the docking portion of the first sub-cavity 111 and the second sub-cavity 112. An annular groove 114 is provided on the stepped portion 113 for receiving the waterproof sealing ring 350.

[0071] The waterproof sealing ring 350 can be, but is not limited to, rubber or foam. The waterproof sealing ring 350 is disposed within the annular groove 114, which can reduce or even prevent the waterproof sealing ring 350 from falling off. In addition, the waterproof sealing ring 350 can reduce or even prevent external dust and moisture from entering the battery cavity 110 and damaging the battery assembly 600 and other components of the self-propelled working device 1.

[0072] Further, please refer to Figure 2 and Figure 3 , the self-propelled working device 1 further includes a battery cover 400. The battery cover 400 is disposed at the opening 110a and is fixed to the body 100.

[0073] The battery cover 400 is disposed at the opening 110a, which can reduce or even prevent external dust and moisture from entering the battery cavity 110 and damaging the battery assembly 600 and other components of the self-propelled working device 1.

[0074] Further, the battery cover 400 further has a first mounting hole. Correspondingly, the body 100 has a second mounting hole, and the second mounting hole corresponds to the first mounting hole. The self-propelled working device 1 further includes a fixing member. The fixing member can be, but is not limited to, a screw or a pin. The fixing member passes through the first mounting hole and the second mounting hole to fix the battery cover 400 to the body 100. In addition, the fixing member can also be removed, and then the battery cover 400 can be removed from the body 100.

[0075] Further, please refer toFigure 7 and Figure 8 , Figure 7 Schematic diagrams of a socket assembly and a battery assembly provided for an embodiment; Figure 8 For Figure 7 Exploded perspective view of the socket assembly and the battery assembly provided in. The self-propelled work device 1 further includes a socket assembly 500. The socket assembly 500 is detachably electrically connected to the battery assembly 600. The first electrode assembly 310 charges the battery assembly 600 through the circuit board 210 and the socket assembly 500.

[0076] Please refer to Figure 8 , Figure 9 and Figure 10 , Figure 9 For Figure 7 Schematic diagram of the socket assembly shown in from one perspective; Figure 10 For Figure 9 Schematic diagram of the socket assembly shown in from another perspective. The socket assembly 500 includes a plug 510 and a mounting base 520. The plug 510 is electrically connected to the first electrode assembly 310.
