[0027] like Figures 1 to 5 、 Figure 14 As shown, an embodiment provides a battery compartment 1000 that can be used in a robot and can be used in conjunction with a battery 2000. In the embodiment, the battery compartment 1000 includes a housing assembly 100, a floating mechanism 200, and a first connector 300.

[0028] The interior of the housing assembly 100 is a hollow structure, which may form an accommodating cavity 101. The housing assembly 100 further includes a first enclosing plate 110 and a first opening 102 that are opposite to each other. The first enclosing plate 110 and the first opening 102 may be disposed at opposite ends of the housing assembly 100, i.e., the accommodating cavity 101 may be located between the first enclosing plate 110 and the first opening 102, and the first opening 102 may be in communication with the accommodating cavity 101.

[0029] In some embodiments, the floating mechanism 200 can be mounted on the first enclosure 110 and exposed to the accommodating cavity 101. Furthermore, the floating mechanism 200 has at least two floating directions. The first connector 300 can be connected to the side of the floating mechanism 200 facing the accommodating cavity 101, with at least a portion of the first connector 300 located within the accommodating cavity 101. Thus, the floating mechanism 200 enables the first connector 300 to move relative to the first enclosure 110 along at least one of the at least two floating directions. Preferably, the floating mechanism 200 can have three intersecting floating directions: a first floating direction X, a second floating direction Y, and a third floating direction Z. In some embodiments, the first floating direction X, the second floating direction Y, and the third floating direction Z can be perpendicular to each other. Both the first floating direction X and the second floating direction Y can be parallel to the first enclosure 110, while the third floating direction Z can be perpendicular to the first enclosure 110. The insertion direction of the first connector 300 can be parallel to the third floating direction Z.

[0030] In other embodiments, the floating mechanism 200 can drive the first connector 300 to move along any two floating directions of the first floating direction X, the second floating direction Y, and the third floating direction Z relative to the first enclosure 110 .

[0031] When assembling the battery 2000 into the battery compartment 1000, the battery 2000 can be inserted into the accommodating cavity 101 through the first opening 102 of the housing assembly 100. The second connector 2200 on the battery 2000 then plugs into the first connector 300 to establish an electrical connection, enabling power and signal transmission. During the plugging process, the floating mechanism 200 drives the first connector 300 to move in the first floating direction X, the second floating direction Y, and the third floating direction Z, ensuring precise alignment between the first connector 300 and the second connector 2200. This improves the efficiency of the plugging and alignment process, and consequently, the assembly efficiency of the battery 2000 and the battery compartment 1000. This also mitigates precision issues that may arise during the manufacturing of the battery compartment 1000 and the battery 2000, reducing the probability of damage to the first connector 300 and the second connector 2200. In addition, when the first connector 300 is subjected to vibration, the floating mechanism 200 can also absorb the vibration, thereby improving the connection stability and reliability between the first connector 300 and the second connector 2200 .

[0032] like Figures 1 to 3As shown, in some embodiments, the housing assembly 100 further includes two opposing second enclosure panels 120 and two opposing third enclosure panels 130. One end of the second enclosure panel 120 and one end of the third enclosure panel 130 are both connected to the first enclosure panel 110, and the other ends of the second enclosure panel 120 and the other ends of the third enclosure panel 130 extend to the first opening 102 and cooperate to define the first opening 102.

[0033] In some embodiments, a guide bar 140 is protruded from the side of the second and third enclosure panels 120 and 130 facing the accommodating cavity 101. The guide bar 140 may be parallel to the first opening 102 and point toward the first enclosure panel 110. That is, the guide bar 140 is parallel to the third floating direction Z. In some embodiments, the guide bar 140 may be fixedly connected to the enclosure panel in which it is located by screws or welding, and the guide bar 140 may extend from the first opening 102 to the first enclosure panel 110. When the battery 2000 is installed in the battery compartment 1000, the guide bar 140 provides support for the battery 2000, reducing the contact area between the battery 2000 surface and the housing assembly 100, thereby reducing friction between the battery 2000 surface and the battery compartment 1000. This reduces assembly resistance during battery 2000 assembly. Furthermore, it reduces wear on the battery 2000 and the battery compartment 1000, thereby extending the service life of the battery 2000 and the battery compartment 1000.

[0034] In some embodiments, two parallel and spaced guide strips 140 may be protruded from each of the second enclosure 120 and the third enclosure 130 .

[0035] In other embodiments, the second and third panels 120, 130 may each be provided with one, three, four, or any other number of guide bars 140. When multiple guide bars 140 are provided on the same panel, the multiple guide bars 140 may be provided in parallel.

[0036] In some embodiments, the end of the guide bar 140 facing the first opening 102 is configured with a first guide slope 141. The first guide slope 141 may be located on the side of the guide bar 140 facing away from the panel on which the guide bar 140 is located. In this embodiment, the first guide slope 141 may gradually slope toward the panel on which the guide bar 140 is located, from the end closest to the first panel 110 to the end further away from the first panel 110. This provides guidance for the battery 2000 during installation, improving the alignment of the battery 2000 with the battery compartment 1000 and, in turn, enhancing battery 2000 installation efficiency.

[0037] In some embodiments, a conductive spring 150 may be fixedly connected to the side of one of the second enclosure panels 120 facing the accommodating cavity 101 by welding or screwing, thereby achieving both mechanical and electrical connection between the conductive spring 150 and the housing assembly 100. The side of the conductive spring 150 facing away from the second enclosure panel 120 to which it is attached may protrude relative to the side of the guide bar 140 on the second enclosure panel 120 facing the accommodating cavity 101. When the battery 2000 is installed in the battery compartment 1000, the conductive spring 150 may make contact and electrically connect with the battery 2000, thereby grounding the battery 2000.

[0038] In some embodiments, a cushioning pad 160 is attached to the side of the first enclosure 110 facing the accommodating cavity 101 to provide a cushioning function. During battery 2000 installation, cushioning pad 160 prevents rigid collision between the battery 2000 and the first enclosure 110. In some embodiments, cushioning pad 160 can be made of a flexible material such as ethylene vinyl acetate (EVA), silicone, or rubber.

[0039] like Figures 2 to 7 、 Figure 14 As shown, in some embodiments, the floating mechanism 200 may include a mounting frame 230 and a first floating assembly 210. The mounting frame 230 may be a U-shaped frame. The mounting frame 230 may be fixedly connected to the side of the first enclosure 110 facing away from the accommodating cavity 101 via screws or welding, with the open end of the mounting frame 230 facing the first enclosure 110. The first floating assembly 210 may be mounted on the mounting frame 230. In some embodiments, the first floating assembly 210 can provide floatation in a first floating direction X and a second floating direction Y.

[0040] In other embodiments, the first float assembly 210 can provide floatation in the first floatation direction X or in the second floatation direction Y.

[0041] In some embodiments, the floating mechanism 200 further includes a second floating assembly 220. The second floating assembly 220 can be mounted on the side of the first floating assembly 210 facing the first enclosure 110. The second floating assembly 220 can provide floatation in a third floating direction Z. Furthermore, a hollow hole 111 is defined on the first enclosure 110, facing the second floating assembly 220, and a first avoidance hole 161 is defined on the cushion 160, facing the hollow hole 111. The side of the second floating assembly 220 facing away from the first floating assembly 210 can be exposed to the accommodating cavity 101 through the hollow hole 111 and the first avoidance hole 161, respectively. In some embodiments, the first connector 300 can be connected to the side of the second floating assembly 220 facing the first enclosure 110, and can be sequentially provided through the hollow hole 111 and the first avoidance hole 161, protruding relative to the side of the cushion 160 facing the accommodating cavity 101. Thus, when the battery 2000 is installed in the battery compartment 1000 , the first connector 300 can be plugged into the second connector 2200 on the battery 2000 .

[0042] In other embodiments, the first connector 300 may also be directly connected to the side of the first floating component 210 facing the first enclosure 110, and the first floating component 210 may drive the first connector 300 to move in the first floating direction X and the second floating direction Y.

[0043] In other embodiments, one end of the second floating assembly 220 may be directly connected to the mounting bracket 230 and located on a side of the mounting bracket 230 facing the first enclosure 110. The first connector 300 may be connected to a side of the second floating assembly 220 facing the first enclosure 110.

[0044] In some embodiments, the first floating assembly 210 may include a first floating plate 212, a fixed plate assembly 211, a plurality of first elastic members 213, and a plurality of second elastic members 214. The fixed plate assembly 211 may include a fixed plate 2111 and a pressure plate 2112, which may be arranged opposite each other along the third floating direction Z. The fixed plate 2111 and the pressure plate 2112 may be fixedly mounted to the side of the mounting frame 230 facing the first enclosure 110 via screws or other means, with the pressure plate 2112 located on the side of the fixed plate 2111 facing the first enclosure 110. Furthermore, the mounting frame 230 may include a through-hole 231 opposite the fixed plate 2111. Portions of the fixed plate 2111 are exposed through the through-hole 231 on the side of the mounting frame 230 facing away from the first enclosure 110. Specifically, portions of the fixed plate 2111 are visible through the through-hole 231 from the side of the mounting frame 230 facing away from the first enclosure 110.

[0045] In some embodiments, the fixed plate assembly 211 is provided with an assembly hole 2113 that extends through both the fixed plate 2111 and the pressure plate 2112 along the third floating direction Z. The first floating plate 212 may be perpendicular to the third floating direction Z. The first floating plate 212 may be disposed in the assembly hole 2113, with an annular first gap 2171 defined between the first floating plate 212 and the inner wall of the assembly hole 2113. This means that the circumferential surface of the first floating plate 212 does not contact the inner wall of the assembly hole 2113. This provides floating space for the first floating plate 212 in both the first floating direction X and the second floating direction Y. Furthermore, the fixed plate assembly 211 may also limit the floating travel of the first floating plate 212 in both the first floating direction X and the second floating direction Y.

[0046] In other embodiments, a gap is provided between the first floating plate 212 and the inner wall of the assembly hole 2113 along the first floating direction X, and gaps are provided between both opposing surfaces of the first floating plate 212 and the inner wall of the assembly hole 2113. Along the second direction Y, both opposing surfaces of the first floating plate 212 may contact the inner wall of the assembly hole 2113.

[0047] In other embodiments, a gap is provided between the first floating plate 212 and the inner wall of the assembly hole 2113 along the second floating direction Y, and gaps are provided between both opposing surfaces of the first floating plate 212 and the inner wall of the assembly hole 2113. Along the first direction X, both opposing surfaces of the first floating plate 212 may contact the inner wall of the assembly hole 2113.

[0048] In some embodiments, the fixed plate 2111 further defines a limiting groove 2114 on the side facing the pressure plate 2112. The limiting groove 2114 can communicate with the assembly hole 2113. It is understood that the limiting groove 2114 can also be annular. An annular limiting protrusion 2121 is provided around the periphery of the first floating plate 212. The limiting protrusion 2121 is inserted into the limiting groove 2114 and abuts between the fixed plate 2111 and the pressure plate 2112. This limits relative movement of the first floating plate 212 and the fixed plate assembly 211 parallel to the third floating direction Z. Furthermore, an annular second gap 2172 is provided between the limiting protrusion 2121 and the inner wall of the limiting groove 2114 facing the assembly hole 2113 to prevent interference with the floating of the first floating plate 212 in the first floating direction X and the second floating direction Y.

[0049] In other embodiments, along the first floating direction X, a gap may be left between the opposing surfaces of the limiting protrusion 2121 and the inner wall of the limiting groove 2114 facing the assembly hole 2113. Along the second floating direction Y, the opposing surfaces of the limiting protrusion 2121 may contact the inner wall of the limiting groove 2114 facing the assembly hole 2113.

[0050] In other embodiments, along the second floating direction Y, a gap may be left between the opposing surfaces of the limiting protrusion 2121 and the inner wall of the limiting groove 2114 facing the assembly hole 2113. Along the first floating direction X, the opposing surfaces of the limiting protrusion 2121 may contact the inner wall of the limiting groove 2114 facing the assembly hole 2113.

[0051] In some embodiments, the first floating plate 212 may be a rectangular plate structure. A pair of sides of the first floating plate 212 may be parallel to the first floating direction X, and another pair of sides of the first floating plate 212 may be parallel to the second floating direction Y.

[0052] In some embodiments, the plurality of first elastic members 213 and the plurality of second elastic members 214 may be disposed on a side of the fixing plate 2111 facing away from the pressing plate 2112 .

[0053] In this embodiment, a plurality of first elastic members 213 may be symmetrically disposed on two opposing sides of the first floating plate 212, and the sides may be parallel to the second floating direction Y. The elastic direction of the first elastic members 213 may be parallel to the first floating direction X. One end of the first elastic member 213 may be fixedly connected to the fixed plate 2111, and the other end of the first elastic member 213 may be fixedly connected to the first floating plate 212. Thus, when the floating mechanism 200 is not subjected to external forces, the cooperation of the plurality of first elastic members 213 can maintain the first floating plate 212 in balance in the first floating direction X.

[0054] In some other embodiments, the plurality of first elastic members 213 may also be unevenly distributed on two opposite sides of the first floating plate 212 .

[0055] In the embodiment, one end of the first elastic member 213 may be fixedly connected to the fixed plate 2111 via a first hanging ear 215 , and the other end of the first elastic member 213 may be fixedly connected to the first floating plate 212 via a second hanging ear 216 .

[0056] Specifically, the first hanging ear 215 can be fixedly connected to the fixed plate 2111 by screwing or welding. One end of the first elastic member 213 can be hung on the first hanging ear 215. The end of the first hanging ear 215 away from the fixed plate 2111 can be configured with a first limiting edge 2151 to prevent the first elastic member 213 from detaching from the first hanging ear 215 along the axial direction of the first hanging ear 215. One end of the second hanging ear 216 can be fixedly connected to the first floating plate 212 by screwing or welding. The other end of the first elastic member 213 can be hung on the second hanging ear 216. The end of the second hanging ear 216 away from the first floating plate 212 can be configured with a second limiting edge 2161 to prevent the second elastic member 214 from detaching from the second hanging ear 216 along the axial direction of the second hanging ear 216.

[0057] In this embodiment, a plurality of second elastic members 214 may be symmetrically disposed on two opposite sides of the first floating plate 212, and these sides may be parallel to the first floating direction X. The elastic direction of the second elastic members 214 may be parallel to the second floating direction Y. One end of the second elastic member 214 may be fixedly connected to the fixed plate 2111, and the other end of the second elastic member 214 may be fixedly connected to the first floating plate 212. Thus, when the floating mechanism 200 is not subjected to external forces, the cooperation of the plurality of second elastic members 214 can maintain the first floating plate 212 in balance in the second floating direction Y.

[0058] In some other embodiments, the plurality of second elastic members 214 may also be unevenly distributed on two opposite sides of the first floating plate 212 .

[0059] In this embodiment, one end of the second elastic member 214 can be fixedly connected to the fixed plate 2111 via a first hook 215, and the other end of the second elastic member 214 can be fixedly connected to the first floating plate 212 via a second hook 216. In this embodiment, the connection method of the second elastic member 214 can be similar to the connection method of the first elastic member 213, and will not be repeated here.

[0060] In the embodiment, both the first elastic member 213 and the second elastic member 214 may be springs.

[0061] In other embodiments, the first elastic member 213 and the second elastic member 214 may also be respectively made of elastic ropes or spring sheets.

[0062] In some embodiments, the second floating assembly 220 includes a guide rod 221, a third elastic member 222, and a second floating plate 223. The guide rod 221 can be positioned along the third floating direction Z through the first floating plate 212. The second floating plate 223 can be fixedly connected to one end of the guide rod 221 via screws, welding, riveting, or clamping. The second floating plate 223 can be positioned on the side of the pressure plate 2112 facing the first enclosure 110. A third limiting edge 2211 is provided protruding from the side of the guide rod 221 away from the second floating plate 223. The third limiting edge 2211 can be positioned on the side of the first floating plate 212 facing away from the pressure plate 2112.

[0063] In this embodiment, the third elastic member 222 can be disposed around the guide rod 221 and abutted between the first floating plate 212 and the second floating plate 223. When the floating mechanism 200 is not subjected to external forces, the third elastic member 222 can be in a naturally extended or compressed state. In some embodiments, the third elastic member 222 can be a spring.

[0064] In other embodiments, the third elastic member 222 may also be a flexible column or a spring.

[0065] In the embodiment, the guide rods 221 and the third elastic members 222 can be arranged in a pair, two pairs, or three pairs as required.

[0066] In an embodiment, the first connector 300 may be fixedly mounted on a side of the second floating plate 223 facing the first enclosure 110. In some embodiments, the first connector 300 may be a connector with a built-in guide column.

[0067] In some embodiments, the second floating assembly 220 further includes a first stopper 224. The first stopper 224 can be configured as a stopper post or a stopper block. The first stopper 224 is fixedly connected to the side of the first floating plate 212 facing the second floating plate 223 via screws or welding, and is located along the floating path of the second floating plate 223. Thus, the first stopper 224 and the third stopper edge 2211 cooperate to limit the floating travel of the second floating plate 223, ensuring smooth insertion of the first connector 300 and the second connector 2200.

[0068] In other embodiments, the floating mechanism 200 may also be made of flexible blocks such as silicone, thermoplastic elastomer (TPE), thermoplastic polyurethane (TPU) or rubber, and floating in the first floating direction X, the second floating direction Y and the third floating direction Z can be achieved through the elastic deformation of the flexible blocks.

[0069] like Figures 1 to 3 as well as Figures 8 to 13 As shown, in some embodiments, the battery compartment 1000 further includes a locking mechanism 400 , which may include a support frame 410 , a sliding member 421 , a guide member 430 , a fourth elastic member 441 , a latch 451 , a fifth elastic member 442 and a driving member 422 .

[0070] Among them, one side of the support frame 410 can be fixedly connected to a second enclosure 120 opposite to the conductive spring sheet 150 by means of bolt connection, bonding or clamping, and is located on the side of the second enclosure 120 away from the accommodating cavity 101. The support frame 410 has an installation cavity 411 and a third opening 412 and a second opening 413, and the installation cavity 411 can be connected to the third opening 412 and the second opening 413. In the embodiment, the third opening 412 can be set along the third floating direction Z. The second opening 413 can be located on the side of the support frame 410 facing the second enclosure 120, and the second opening 413 can be set along the second floating direction Y. In addition, a second avoidance hole 414 arranged along the first floating direction X is also provided on the support frame 410, and the second avoidance hole 414 is connected to the installation cavity 411.

[0071] In some embodiments, one end of the guide member 430 is received in the mounting cavity 411 and fixedly connected to the support frame 410 via bolts or adhesive. The other end of the guide member 430 may be inserted through the second opening 413 along the second floating direction Y and may protrude relative to the support frame 410 toward the side of the second enclosure 120. In some embodiments, the end of the guide member 430 protruding relative to the second opening 413 may be inserted through the second enclosure 120. The end surface of the guide member 430 proximal to the second enclosure 120 may be flush with, or slightly lower than, the side of the second enclosure 120 facing the accommodating cavity 101. Furthermore, the guide member 430 may define a mounting hole 431 extending through the guide member 430 along the second floating direction Y and a notch 432 extending along the second floating direction Y. The notch 432 may be disposed away from the second opening 413. In an embodiment, a connecting hole 121 communicating with the accommodating cavity 101 may be defined on the second enclosure 120. The connecting hole 121 may have an axial direction perpendicular to the direction of the first opening 102 pointing toward the first enclosure 110. The axial direction of the first connecting hole 121 may be perpendicular to the third floating direction Z. In some embodiments, the axial direction of the connecting hole 121 may be parallel to the second floating direction Y.

[0072] In other embodiments, the locking mechanism 400 may be installed on a side of a third enclosure 130 away from the accommodating cavity 101. Accordingly, the connecting hole 121 may be opened on the third enclosure 130, and the axial direction of the connecting hole 121 may be parallel to the first floating direction X.

[0073] In some embodiments, the sliding member 421 is slidably disposed within the mounting cavity 411 along the third floating direction Z and is located on the side of the guide member 430 facing the third opening 412. Furthermore, the side of the sliding member 421 facing away from the second opening 413 may be configured with two spaced sliding surfaces 4211, which may lie in the same plane. In some embodiments, the sliding surfaces 4211 may be inclined relative to the third floating direction Z. Specifically, the sliding surface 4211 may gradually tilt toward the second opening 413 from an end proximal to the third opening 412 to an end distal to the third opening 412.

[0074] In one embodiment, the driving member 422 can be mounted on a side of the support frame 410 facing the second enclosure 120. The output shaft of the driving member 422 can be passed through the third opening 412 and abut against the sliding member 421. The driving member 422 can be used to drive the sliding member 421 toward the guide member 430. In some embodiments, the driving member 422 can be an electric push rod.

[0075] In other embodiments, the driving member 422 may also be a pneumatic cylinder or an electric cylinder.

[0076] In some embodiments, the fourth elastic member 441 can be arranged along the third floating direction Z and disposed between the guide member 430 and the sliding member 421. When the fourth elastic member 441 is in a compressed state, the fourth elastic member 441 can exert an elastic force on the sliding member 421, causing the sliding member 421 to move away from the guide member 430. In some embodiments, the fourth elastic member 441 can be a spring.

[0077] In some embodiments, the latch 451 and the fifth elastic member 442 are both disposed in the mounting hole 431. The latch 451 can slide through the mounting hole 431 along the second floating direction Y, and one end of the latch 451 can be telescopically arranged relative to the mounting hole 431 toward one end of the guide member 430. When the latch 451 extends relative to the mounting hole 431 toward one end of the second enclosure 120, the latch 451 can protrude relative to the second enclosure 120 toward one side of the accommodating cavity 101.

[0078] In this embodiment, the fifth elastic member 442 can also be arranged along the second floating direction Y and located between the latch 451 and the inner wall of the mounting cavity 411. One end of the fifth elastic member 442 can abut an inner wall of the mounting cavity 411 opposite the second opening 413, while the other end of the fifth elastic member 442 can abut the latch 451. In this embodiment, when the fifth elastic member 442 is in a compressed state, the fifth elastic member 442 can be used to drive the latch 451 toward the second enclosure 120. In some embodiments, the fifth elastic member 442 can be a spring.

[0079] In some embodiments, two symmetrical rolling elements 452 are rotatably connected to one end of the latch 451 facing the fifth elastic element 442. The rotational axes of the rolling elements 452 may be parallel to the first floating direction X. Furthermore, the rolling elements 452 may be inserted into the notch 432 , and the two rolling elements 452 may abut against the two sliding surfaces 4211 on the sliding element 421 in a one-to-one correspondence. Accordingly, the rolling elements 452 may be located on the side of the sliding surface 4211 facing away from the second opening 413 .

[0080] In some embodiments, the locking mechanism 400 further includes a blocking member 460. The blocking member 460 is disposed at the third opening 412 and can be fixedly connected to the support frame 410 via bolts or other means. In some embodiments, the blocking member 460 can be used to prevent the sliding member 421 from sliding out of the third opening 412. The blocking member 460 has a connecting port 461 that communicates with the third opening 412. The output shaft of the driving member 422 can be disposed through the connecting port 461 and abut against the sliding member 421.

[0081] In some embodiments, a Hall sensor 471 is further provided at the bottom of the support frame 410, and the Hall sensor 471 can be provided near the guide member 430 relative to the third opening 412. The Hall sensor 471 is electrically connected to the driving member 422. A magnetic member 472 is provided on the sliding member 421 to cooperate with the Hall sensor 471. The sliding member 421 has a preset position. When the sliding member 421 is in the preset position, the end face of the latch 451 facing away from the end of the fifth elastic member 442 can be flush with the side surface of the guide strip 140 on the second enclosure 120 where the locking mechanism 400 is located facing the accommodating cavity 101. In the embodiment, when the driving member 422 drives the sliding member 421 to slide to the preset position, the magnetic member 472 triggers the Hall sensor 471, and the Hall sensor 471 triggers the driving member 422 to stop working.

[0082] In some embodiments, the locking mechanism 400 further includes a gripping member 480. The gripping member 480 can be inserted into the second avoidance hole 414 along the first floating direction X and extend into the mounting cavity 411 to connect with the sliding member 421. During use, an operator can apply force to the sliding member 421 through the gripping member 480, causing the sliding member 421 to move toward or away from the guide member 430.

[0083] During use, when the battery 2000 needs to be installed in the battery compartment 1000, the driver 422 is activated, causing the sliding member 421 to squeeze the fourth elastic member 441 and move toward the guide member 430. Under the squeezing action of the sliding surface 4211, the rolling member 452 can move away from the second opening 413. Driven by the rolling member 452, the latch 451 can squeeze the fifth elastic member 442 and move relative to the second enclosure 120 away from the accommodating cavity 101. When the latch 451 is in place, the magnetic member 472 acts on the Hall effect sensor 471, deactivating the driver 422. The battery 2000 can then be installed in the battery compartment 1000. For example, the latch 451 is considered in place when the end surface of the latch 451 facing away from the fifth elastic member 442 is flush with the surface of the guide strip 140 on the second enclosure 120, where the locking mechanism 400 is located, facing the accommodating cavity 101.

[0084] After the battery 2000 is properly installed, the driver 422 can be activated to retract its output shaft. Under the elastic force of the fourth elastic member 441, the slider 421 can move away from the guide member 430, thereby releasing the pressure of the sliding surface 4211 on the rolling member 452. Under the elastic force of the fifth elastic member 442, the latch 451 can protrude from the second enclosure 120 toward the side of the accommodating cavity 101 and be inserted into the latch hole 2110 on the battery 2000, thereby locking the battery 2000 with the battery compartment 1000.

[0085] like Figure 1 、 Figure 14 and Figure 15 As shown, the embodiment further provides a power supply device, including a battery 2000 and a battery compartment 1000 provided in the embodiment.

[0086] The battery 2000 may include a battery body 2100 and a second connector 2200 protruding from one end of the battery body 2100. The second connector 2200 may be electrically connected to the battery body 2100. When the battery 2000 is installed in the battery compartment 1000, the second connector 2200 may be plugged into the first connector 300 to form an electrical connection, enabling the transmission of power and signals. In this embodiment, the second connector 2200 may be a connector with a guide hole and adapted to the first connector 300.

[0087] In some embodiments, a second stopper 2300 is further provided protruding from one end of the battery body 2100 facing the second connector 2200. The second stopper 2300 can be configured as a stopper block or a stopper post. When the second connector 2200 is plugged into the first connector 300, the second stopper 2300 abuts against the cushion 160, limiting the insertion depth of the second connector 2200 and the first connector 300, preventing overshoot and reducing the possibility of damage to the first connector 300 and the second connector 2200.

[0088] Furthermore, the end of the battery body 2100 facing the second connector 2200 is equipped with two second guide slopes 2120 disposed opposite each other. The second guide slopes 2120 gradually slope away from the central axis of the battery 2000 from the end closest to the second connector 2200 to the end further away from the second connector 2200. This provides guidance when installing the battery 2000 into the battery compartment 1000, further improving installation efficiency.

[0089] In some embodiments, the battery body 2100 is further provided with a latch hole 2110 adapted to fit the latch 451. When the battery 2000 and the battery compartment 1000 are installed, the latch 451 in the battery compartment 1000 can be inserted into the latch hole 2110 on the battery body 2100 to lock the battery 2000 and prevent the battery 2000 from being removed from the battery compartment 1000.

[0090] In some embodiments, a handle 2400 is provided on the side of the battery body 2100 facing away from the second connector 2200 to facilitate the user to disassemble and assemble the battery 2000.

[0091] When installing the battery 2000 in the battery compartment 1000, a worker or a robot can grasp the handle 2400 of the battery 2000, with the end of the battery 2000 equipped with the second connector 2200 facing the battery compartment 1000. The guide bar 140 and the second guide slope 2120 facilitate smooth insertion of the battery 2000 into the receiving cavity 101 of the battery compartment 1000. The battery 2000 then contacts the conductive spring 150 in the battery compartment 1000, and the guide post on the first connector 300 gradually penetrates the guide hole of the second connector 2200. The first floating assembly 210 provides the first connector 300 with float in the first floating direction X and the second floating direction Y, ensuring accurate alignment between the first connector 300 and the second connector 2200. The battery 2000 is further pushed into the battery compartment 1000, and the first connector 300, under the action of the second float assembly 220, floats in the third floating direction Z. Once the battery 2000 is properly installed, the first connector 300 can be plugged into the second connector 2200, establishing an electrical connection. The latch 451 of the locking mechanism 400 can then be inserted into the latch hole 2110 of the battery 2000, locking the battery 2000.

[0092] The steps for disassembling the battery 2000 may be the opposite of the steps for installing the battery 2000 .

[0093] A robot is also provided in the embodiment, which may include the battery compartment 1000 and the battery 2000 provided in the embodiment. The battery 2000 can be detachably installed in the battery compartment 1000, and the second connector 2200 in the battery 2000 can be plugged and connected to the first connector 300 in the battery compartment 1000.
