Those skilled in the art can explicitly and implicitly understand that the embodiments described in the present application can be combined with other embodiments.

[0033] In the description and claims of this application and the above-mentioned drawings, terms such as "first" and "second" are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion.

[0034] One embodiment of the present application provides an autonomous mobile device 1. The autonomous mobile device 1 can be, but is not limited to, a device capable of automatic movement such as a lawn mower. In the schematic diagram of this embodiment, taking the autonomous mobile device 1 as a lawn mower as an example for illustration, it can be understood that it should not be construed as a limitation on the autonomous mobile device 1 provided by the embodiment of the present application.

[0035] Please refer to Figure 1 、 Figure 2 and Figure 3 , Figure 1 is a schematic diagram of the autonomous mobile device provided by one embodiment of the present application; Figure 2 is Figure 1 a three-dimensional exploded schematic diagram of the autonomous mobile device in Figure 3 is a cross-sectional schematic diagram of the autonomous mobile device provided by another embodiment of the present application. The autonomous mobile device 1 includes a device main body 10, an electrical connection component 20, and a battery module 30. A receiving cavity 110 is provided at the rear end of the device main body 10, and the receiving cavity 110 has an opening 110a. The electrical connection component 20 includes a fixing seat 210, a first connection terminal 220 provided on the fixing seat 210, and a clamping hole 210a. The fixing seat 210 is provided on the inner wall surface of the receiving cavity 110, and the first connection terminal 220 is located at one end of the fixing seat 210 away from the opening 110a. The battery module 30 includes a battery body 310 and a clamping component 320 provided thereon. Please refer to Figure 4 and Figure 5 , and Figure 6 and Figure 7 , Figure 4 is Figure 2 a partial structural schematic diagram of the autonomous mobile device shown in

[0036] Figure 5 is Figure 4 an exploded schematic diagram of the partial structure shown in Figure 6 is a partial structural schematic diagram of the autonomous mobile device shown in another embodiment; Figure 7 is Figure 6Exploded schematic view of a partial structure shown therein. The battery body 310 has a second connection terminal 311, and the second connection terminal 311 is electrically connected to the first connection terminal 220. The clamping assembly 320 includes a clamping portion 321, a pressing portion 322, and an elastic member 323. The clamping portion 321 is in clamping fit with the clamping hole 210a to fix the battery body 310, the elastic member 323 is located between the pressing portion 322 and the battery body 310, and the pressing portion 322 can cause the clamping portion 321 to disengage from the clamping hole 210a under an external force.

[0037] The so-called device main body 10 refers to the component that can complete the main functions of the autonomous mobile device 1. For example, when the autonomous mobile device 1 is a lawn mower, the device main body 10 is the main component that can complete the lawn mowing function. For instance, when the autonomous mobile device 1 is a lawn mower, the device main body 10 may include components such as a cutting portion for mowing, traveling wheels for traveling, and a housing for mounting the cutting portion and the traveling wheels.

[0038] The device main body 10 has a receiving cavity 110, and the receiving cavity 110 is used to receive the electrical connection assembly 20 and the battery module 30. The receiving cavity 110 has an opening 110a for the battery module 30 to be installed into the receiving cavity 110 or removed from the receiving cavity 110.

[0039] The rear end of the device main body 10 refers to the end located at the rear in the traveling direction when the autonomous mobile device 1 is traveling. The receiving cavity 110 is provided at the rear end of the device main body 10. Therefore, the battery module 30 is disposed in the receiving cavity 110, and the battery module 30 is also located at the rear end of the device main body 10. The battery module 30 being located at the rear end of the device main body 10 facilitates the installation and removal of the battery module 30. In addition, the battery module 30 being located at the rear end of the device main body 10 can also balance the weights of the front end and the rear end of the autonomous mobile device 1, making the center of gravity of the autonomous mobile device 1 close to the middle and not easily tipping over.

[0040] The electrical connection assembly 20 is a component that realizes electrical connection with the battery module 30. The fixed seat 210 in the electrical connection assembly 20 can also be referred to as a mounting seat, and the first connection terminal 220 can be fixed. Generally speaking, the fixed seat 210 is an insulating fixed seat 210.

[0041] The first connection terminal 220 is a conductive connection terminal. For example, the first connection terminal 220 can be a copper connection terminal, an aluminum connection terminal, or the like. Correspondingly, the second connection terminal 311 is also a conductive connection terminal, and the second connection terminal 311 can be a copper connection terminal, an aluminum connection terminal, or the like. In one embodiment, the second connection terminal 311 contacts the first connection terminal 220 to achieve electrical connection between the second connection terminal 311 and the first connection terminal 220.

[0042] The clamping hole 210a is located on the fixing base 210. In one embodiment, the clamping hole 210a can penetrate through two opposite surfaces of the fixing base 210. At this time, the clamping hole 210a is also called a through hole. In another embodiment, the clamping hole 210a is a blind hole. The type of the clamping hole 210a is not limited in the embodiments of the present application.

[0043] The fixing base 210 is provided on the inner wall surface of the accommodating cavity 110. Therefore, the fixing base 210 can be fixedly connected to the device body 10.

[0044] The clamping component 320 cooperates with the fixing base 210, and the clamping component 320 can be fixed to the fixing base 210; in addition, the clamping component 320 can also be separated from the fixing base 210 to achieve detachable connection between the battery module 30 and the fixing base 210. Specifically, the clamping portion 321 of the clamping component 320 cooperates with the clamping hole 210a to fixedly fix the battery body 310 to the fixing base 210. Since the fixing base 210 is provided on the inner wall surface of the accommodating cavity 110, the battery body 310 is fixed to the device body 10 through the fixing base 210.

[0045] The elastic member 323 is located between the pressing portion 322 and the battery body 310. The pressing portion 322 can cause the clamping portion 321 to disengage from the clamping hole 210a under the action of an external force. Therefore, the elastic member 323 approaches the battery body 310 under the action of the external force, so that the clamping portion 321 is in a detachable state that can disengage from the clamping hole 210a; it can also enter a fixed state (also called a restored state) from the detachable state after the external force is withdrawn. In one embodiment, the material of the elastic member 323 itself does not have elasticity, but through the structural design of the elastic member 323, the elastic member 323 can approach or deviate from the battery body 310.

[0046] In another embodiment, the elastic member 323 may be, but is not limited to, a spring, or elastic plastic, etc. In this embodiment, no limitation is imposed on the elastic member 323. The elastic member 323 can be compressed or elongated under the action of an external force.

[0047] In one embodiment, when the engaging portion 321 is engaged with the engaging hole 210a to fix the battery body 310, the elastic member 323 is at a first length. Since the elastic member 323 is located between the pressing portion 322 and the battery body 310, when the pressing portion 322 is pressed, the pressing portion 322 squeezes the elastic member 323, and the elastic member 323 is compressed. The elastic member 323 is at a second length. At this time, the engaging portion 321 can be disengaged from the engaging hole 210a, and the battery module 30 can be removed from the fixing base 210. Wherein, the second length is less than the first length.

[0048] In other words, the battery module 30 has a fixed state fixed to the fixing base 210 and a detachable state detachable from the fixing base 210. When the battery module 30 is in the fixed state, the elastic member 323 is at a first length; when the battery module 30 is in the detachable state, the elastic member 323 is at a second length, wherein the second length is less than the first length.

[0049] It can be understood that when the battery module 30 is in the fixed state, the elastic member 323 is in a compressed state. Thus, the probability of the engaging portion 321 falling off from the engaging hole 210a can be reduced or even avoided. It can be understood that when the battery module 30 is in the fixed state, the elastic member 323 is in a compressed state; then, when the battery module 30 is in the detachable state, the elastic member 323 is also in a compressed state.

[0050] In summary, for the autonomous mobile device 1 provided in this embodiment, a receiving cavity 110 is provided at the rear end of the device body 10. Therefore, the battery module 30 is disposed in the receiving cavity 110, and the battery module 30 is also located at the rear end of the device body 10. The battery module 30 being located at the rear end of the device body 10 facilitates the installation and removal of the battery module 30. The autonomous mobile device 1 provided in this embodiment fixes the battery body 310 to the fixing seat 210 through the cooperation of the engaging portion 321 and the engaging hole 210a, and then fixes it to the device body 10. In addition, the engaging component 320 includes an engaging portion 321, a pressing portion 322, and an elastic member 323. The engaging portion 321 is engaged with the engaging hole 210a to fix the battery body 310. The elastic member 323 is located between the pressing portion 322 and the battery body 310. The pressing portion 322 can cause the engaging portion 321 to disengage from the engaging hole 210a under an external force, thereby facilitating the removal of the battery body 310 from the fixing seat 210 and facilitating the replacement of the battery module 30.

[0051] Further, one of the first connection terminal 220 and the second connection terminal 311 is a male plug, and the other of the first connection terminal 220 and the second connection terminal 311 is a female socket. The battery body 310 and the electrical connection assembly 20 are electrically connected through the plugging and mating of the male plug and the female socket.

[0052] Specifically, in this embodiment, the first connection terminal 220 is a male plug, and the second connection terminal 311 is a female socket. In other embodiments, the first connection terminal 220 is a female socket, and correspondingly, the second connection terminal 311 is a male plug. The male plug is inserted into the female socket to electrically connect the male plug and the female socket, thereby realizing the electrical connection between the battery body 310 and the electrical connection assembly 20. In addition, when the male plug is inserted into the female socket, in addition to realizing electrical connection, the male plug and the female socket are also fixed to each other.

[0053] In the autonomous mobile device 1 provided in the embodiment of the present application, one of the first connection terminal 220 and the second connection terminal 311 is a male plug, and the other of the first connection terminal 220 and the second connection terminal 311 is a female socket. The battery body 310 and the electrical connection assembly 20 are electrically connected through the plugging and mating of the male plug and the female socket, and the structure is simple and easy to implement.

[0054] Next, a detailed introduction will be given to the first connection terminal 220 provided by the embodiment of the present application. In this embodiment, the first conductive portion 2212 is a male plug, and the second connection terminal 311 is a female plug. Please refer to Figure 8 and Figure 9 , Figure 8 which Figure 5 is a schematic structural diagram of the first connection terminal shown in Figure 9 and Figure 7 is a schematic structural diagram of the first connection terminal shown in

[0055] The first connection terminal 220 includes a base 221 and a plurality of first conductive portions 2212. The base 221 is disposed at an end of the fixed seat 210 facing away from the clamping hole 210a. The plurality of first conductive portions 2212 are carried on and exposed from the base 221, and the plurality of first conductive portions 2212 are spaced apart. The first conductive portion 2212 is used for electrical connection with the first connection terminal 220.

[0056] Further, the first connection terminal 220 further includes a plurality of first conductive portions 2213. The first conductive portion 2213 is electrically connected to the first conductive portion 2212, and different first conductive portions 2213 are connected to different first conductive portions 2212. Specifically, the base 221 includes a first surface 221a and a second surface 221b that are bent and connected. The first conductive portion 2212 is disposed and protrudes from the first surface 221a. The first conductive portion 2213 is disposed and protrudes from the second surface 221b. The arrangement of the first conductive portion 2212 and the first conductive portion 2213 can make the first connection terminal 220 have a relatively small height. Specifically, the base 221 further includes a third surface 221c facing away from the second surface 221b. The dimension from the third surface 221c to the second surface 221b is the height of the base 221.

[0056] Further, in an embodiment, the accommodating cavity 110 extends along the traveling direction of the autonomous mobile device 1, and one end of the accommodating cavity 110 close to the opening 110a is higher than one end of the accommodating cavity 110 away from the opening 110a.

[0057] One end of the accommodating cavity 110 close to the opening 110a is higher than one end of the accommodating cavity 110 away from the opening 110a. Therefore, to a certain extent, it is possible to reduce or even prevent the battery module 30 from falling off from the accommodating cavity 110.

[0058] Further, please refer to Figure 10 , Figure 10 which Figure 6Schematic cross-sectional view of the structure shown in the figure along line II-II. At least one of the fixing base 210 and the battery body 310 is constructed with a guiding groove, and at least one of the fixing base 210 and the battery body 310 is constructed with a guiding protrusion. The first connection terminal 220 and the second connection terminal 311 are directionally electrically connected through the cooperation of the guiding protrusion and the guiding groove.

[0059] In one embodiment, the fixing base 210 is at least constructed with a guiding groove, and the battery body 310 is at least constructed with a guiding protrusion. The guiding protrusion is received in the guiding groove to realize the fixation of the fixing base 210 and the battery body 310.

[0060] In another embodiment, the battery body 310 is at least constructed with a guiding groove, and the fixing base 210 is at least constructed with a guiding protrusion. The guiding protrusion is received in the guiding groove to realize the fixation of the fixing base 210 and the battery body 310.

[0061] Please refer to Figure 10 , in this embodiment, the fixing base 210 is simultaneously constructed with a guiding groove 210c and a guiding protrusion 210d. Correspondingly, the battery body 310 is simultaneously constructed with a guiding groove 310a and a guiding protrusion 310b. Among them, the guiding groove 310a of the battery body 310 is used to receive the guiding protrusion 210d of the fixing base 210; correspondingly, the guiding protrusion 310b of the battery body 310 is received in the guiding groove 210c of the fixing base 210. In this way, the fixing base 210 and the battery body 310 can be better fixed.

[0062] Next, the structure of the fixing base 210 will be described in detail. Further, please refer to Figure 11 , Figure 11 For Figure 7 is a schematic structural view of the fixing base in

[0063] The first surface 211a and the second surface 211b are two surfaces of the base portion 211 that face away from each other. When the fixing seat 210 is located on the inner wall surface of the accommodating cavity 110 and at the top of the accommodating cavity 110, the first surface 211a is the lower surface of the base body portion, and the second surface 211b is the lower surface of the base portion 211. It can be understood that as the position of the fixing seat 210 in the accommodating cavity 110 is different, the positions of the first surface 211a and the second surface 211b are also different. Here, it is defined that the surface of the base portion 211 facing the battery module 30 is the first surface 211a, and the surface of the base portion 211 facing the cavity wall of the accommodating cavity 110 is the second surface 211b.

[0064] The second surface 211b is configured with a mounting groove 211c. In other words, the opening 110a of the mounting groove 211c is located on the second surface 211b. The second mounting groove 211c is used for mounting the first connection terminal 220. A first through hole 211d penetrating the first surface 211a and the second surface 211b is configured on the wall surface of the mounting groove 211c. Therefore, the first connection terminal 220 can be exposed on the first surface 211a through the first through hole 211d.

[0065] In this embodiment, the first through hole 211d is configured on the bottom wall of the mounting groove 211c. In other words, the first through hole 211d is located on the bottom wall of the mounting groove 211c. It can be understood that in other embodiments, the first through hole 211d is located on the side wall of the mounting groove 211c. As long as the first through hole 211d is configured on the wall surface of the mounting groove 211c and the first connection terminal 220 can be connected to the first surface 211a through the first through hole 211d.

[0066] The first connection terminal 220 is exposed on the first surface 211a. Therefore, it is convenient for the first connection terminal 220 to be electrically connected to the second connection terminal 311.

[0067] In this embodiment, the base portion 211 has a first end portion 2111 and a second end portion 2112 that face away from each other. The first end portion 2111 has the clamping hole 210a, and the second end portion 2112 has the mounting groove 211c. In other words, the clamping hole 210a and the mounting groove 211c are respectively located at two opposite end portions of the base portion 211. In this way, even if the clamping hole 210a, the mounting groove 211c and the first through hole 211d are provided on the base portion 211, the base portion 211 can still have a relatively high structural strength.

[0068] In this embodiment, the first through hole 211d is located at one end of the mounting groove 211c close to the first end portion 2111. In this way, the end face of the first through hole 211d away from the second end portion 2112 can be avoided from being damaged, and the structural strength of the base portion 211 is further improved.

[0069] Further, please refer to Figure 3 , the accommodating cavity 110 includes a first cavity 111 and a second cavity 112 that communicate with each other. The cross-sectional area of the first cavity 111 is smaller than the cross-sectional area of the second cavity 112. Most of the battery module 30 is located in the first cavity 111, and the remaining part of the battery module 30 and the pressing portion 322 are both located in the second cavity 112.

[0070] In this embodiment, the first cavity 111 is the part of the accommodating cavity 110 facing away from the opening 110a, and the second cavity 112 has the opening 110a. The cross-sectional area of the first cavity 111 is smaller than the cross-sectional area of the second cavity 112. Therefore, when the cross-sectional areas of each part of the battery module 30 are the same or approximately the same, the part of the battery module 30 located in the first cavity 111 can be better fixed in the first cavity 111. The cross-sectional area of the second cavity 112 is larger, and the pressing portion 322 is located in the second cavity 112, which is convenient for the user to insert their hand or a tool into the second cavity 112 to press the pressing portion 322 to disassemble and remove the battery module 30; or, it is convenient to put the battery module 30 into the accommodating cavity 110 through the second cavity 112.

[0071] Most of the battery module 30 is located in the first cavity 111, that is, more than or equal to one-half of the battery module 30 is located in the first cavity 111.
