[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0064] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0065] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0066] like Figures 1 to 5 , Figure 14 As shown, the embodiment provides a battery compartment 1000, which can be applied in a robot and 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.

[0067] The housing assembly 100 has a hollow internal structure, which can form a receiving cavity 101. The housing assembly 100 also includes a first surrounding plate 110 and a first opening 102, which can be respectively disposed at both ends of the housing assembly 100, that is, the receiving cavity 101 can be located between the first surrounding plate 110 and the first opening 102, and the first opening 102 can communicate with the receiving cavity 101.

[0068] In some embodiments, the floating mechanism 200 may be mounted on the first enclosure 110 and exposed in the receiving cavity 101. Additionally, the floating mechanism 200 has at least two floating directions. A first connector 300 may be connected to the side of the floating mechanism 200 facing the receiving cavity 101, and at least a portion of the first connector 300 is located within the receiving 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 may 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 may be perpendicular to each other. The first floating direction X and the second floating direction Y may both be parallel to the first enclosure 110, and the third floating direction Z may be perpendicular to the first enclosure 110. The insertion direction of the first connector 300 may be parallel to the third floating direction Z.

[0069] In other embodiments, the floating mechanism 200 can drive the first connector 300 to move below the first enclosure 110 along any two of the first floating directions X, the second floating direction Y, and the third floating direction Z.

[0070] When assembling the battery 2000 into the battery compartment 1000, the battery 2000 can be inserted into the receiving cavity 101 from one end of the first opening 102 of the housing assembly 100, and the second connector 2200 on the battery 2000 can be inserted into the first connector 300 to form an electrical connection, realizing the transmission of electrical energy and signals. During the insertion process of the second connector 2200 and the first connector 300, the floating mechanism 200 can drive the first connector 300 to move in the first floating direction X, the second floating direction Y, and the third floating direction Z, so that the first connector 300 and the second connector 2200 are precisely aligned, improving the alignment and insertion efficiency of the first connector 300 and the second connector 2200, thereby improving the assembly efficiency of the battery 2000 and the battery compartment 1000. At the same time, it can also avoid the precision problems caused by the manufacturing of the battery compartment 1000 and the battery 2000, and reduce 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 absorb the vibration, thereby improving the connection stability and reliability between the first connector 300 and the second connector 2200.

[0071] like Figures 1 to 3As shown, in some embodiments, the housing assembly 100 further includes two opposing second enclosures 120 and two opposing third enclosures 130. One end of each of the second enclosures 120 and the third enclosure 130 is connected to the first enclosure 110, and the other ends of each of the second enclosures 120 and the third enclosure 130 extend to the position of the first opening 102 and cooperate to define the first opening 102.

[0072] In some embodiments, guide strips 140 protrude from the side of the second enclosure 120 and the third enclosure 130 facing the receiving cavity 101. The guide strips 140 are parallel to the direction pointing from the first opening 102 to the first enclosure 110, i.e., parallel to the third floating direction Z. In the embodiments, the guide strips 140 are fixedly connected to the enclosure at their location by means of screws or welding, and the guide strips 140 extend from the first opening 102 to the first enclosure 110. When the battery 2000 is installed in the battery compartment 1000, the guide strips 140 provide support for the battery 2000, reducing the contact area between the surface of the battery 2000 and the housing assembly 100, thereby reducing friction between the surface of the battery 2000 and the battery compartment 1000. On the one hand, this reduces assembly resistance during battery 2000 assembly. On the other hand, it also reduces wear on the battery 2000 and the battery compartment 1000, extending their service life.

[0073] In some embodiments, each of the second enclosure 120 and the third enclosure 130 may have two parallel and spaced guide strips 140 protruding from it.

[0074] In other embodiments, each of the second enclosure 120 and the third enclosure 130 may have one, three, four, or any other number of guide strips 140 protruding from it. When multiple guide strips 140 are provided on the same enclosure, the multiple guide strips 140 may be arranged in parallel.

[0075] In some embodiments, a first guide slope 141 is provided at the end of the guide strip 140 facing the first opening 102. The first guide slope 141 may be located on the side of the guide strip 140 away from the surrounding panel on which the guide strip 140 is located. In this embodiment, the first guide slope 141 may gradually slope from the end near the first surrounding panel 110 to the end away from the first surrounding panel 110, towards the side near the surrounding panel on which the guide strip 140 is located. Thus, when the battery 2000 is installed, it can provide a guiding function for the battery 2000, improve the alignment efficiency between the battery 2000 and the battery compartment 1000, and further improve the installation efficiency of the battery 2000.

[0076] In some embodiments, a conductive spring 150 may be fixedly connected to the side of one of the second enclosure plates 120 facing the receiving cavity 101 by means of welding or screw connection, which can simultaneously realize the mechanical connection and electrical connection between the conductive spring 150 and the housing assembly 100. The side of the conductive spring 150 opposite to the second enclosure plate 120 to which it is connected may protrude relative to the side of the guide strip 140 on the second enclosure plate 120 facing the receiving cavity 101. When the battery 2000 is installed in the battery compartment 1000, the conductive spring 150 can make contact with the battery 2000 for electrical connection, realizing the grounding of the battery 2000.

[0077] In some embodiments, a cushioning pad 160 is also fitted onto the side of the first enclosure 110 facing the receiving cavity 101 to provide a cushioning function. During the installation of the battery 2000, the cushioning pad 160 can prevent rigid collisions between the battery 2000 and the first enclosure 110. In some embodiments, the cushioning pad 160 may be made of flexible materials such as ethylene-vinyl acetate copolymer (EVA), silicone, or rubber.

[0078] 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 is fixedly connected to the side of the first enclosure 110 opposite to the receiving cavity 101 by means of screws or welding, and the open end of the mounting frame 230 may face 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 is capable of providing floating in a first floating direction X and a second floating direction Y.

[0079] In other embodiments, the first floating component 210 is capable of providing floating in a first floating direction X or floating in a second floating direction Y.

[0080] In some embodiments, the floating mechanism 200 further includes a second floating component 220. The second floating component 220 may be installed on the side of the first floating component 210 facing the first enclosure 110. The second floating component 220 is capable of providing floating in a third floating direction Z. In addition, the first enclosure 110 has a perforation 111 opposite to the second floating component 220, and the buffer pad 160 may have a first clearance hole 161 opposite to the perforation 111. The side of the second floating component 220 away from the first floating component 210 may be exposed to the receiving cavity 101 through the perforation 111 and the first clearance hole 161 in sequence. In an embodiment, the first connector 300 may be connected to the side of the second floating component 220 facing the first enclosure 110, and protrudes from the side of the buffer pad 160 facing the receiving cavity 101 through the perforation 111 and the first clearance hole 161 in sequence. Therefore, 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.

[0081] 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.

[0082] In other embodiments, one end of the second floating component 220 may be directly connected to the mounting bracket 230 and located on the side of the mounting bracket 230 facing the first enclosure 110. The first connector 300 may be connected to the side of the second floating component 220 facing the first enclosure 110.

[0083] In some embodiments, the first floating assembly 210 may include a first floating plate 212, a fixed plate group 211, a plurality of first elastic elements 213, and a plurality of second elastic elements 214. The fixed plate group 211 may include a fixed plate 2111 and a pressure plate 2112, which are arranged opposite to each other along a third floating direction Z. The fixed plate 2111 and the pressure plate 2112 are fixedly installed on the side of the mounting frame 230 facing the first enclosure 110 by means of screws or other methods, and the pressure plate 2112 may be located on the side of the fixed plate 2111 facing the first enclosure 110. Furthermore, the mounting frame 230 is provided with a through hole 231 opposite to the fixed plate 2111. A portion of the fixed plate 2111 is exposed through the through hole 231 on the side of the mounting frame 230 away from the first enclosure 110, allowing a portion of the structure of the fixed plate 2111 to be seen from the side of the mounting frame 230 away from the first enclosure 110 through the through hole 231.

[0084] In some embodiments, the fixed plate assembly 211 has an assembly hole 2113, which can penetrate both the fixed plate 2111 and the pressure plate 2112 along the third floating direction Z. The first floating plate 212 can be perpendicular to the third floating direction Z. The first floating plate 212 can be disposed in the assembly hole 2113, and an annular first gap 2171 is provided between the first floating plate 212 and the inner wall of the assembly hole 2113, that is, the peripheral surface of the first floating plate 212 does not contact the inner wall of the assembly hole 2113, thereby providing floating space for the first floating plate 212 in the first floating direction X and the second floating direction Y. At the same time, the fixed plate assembly 211 can also limit the floating stroke of the first floating plate 212 in the first floating direction X and the second floating direction Y.

[0085] In other embodiments, along the first floating direction X, there is a gap between the first floating plate 212 and the inner wall of the mounting hole 2113, and gaps are also provided between the opposite two surfaces of the first floating plate 212 and the inner wall of the mounting hole 2113. Along the second direction Y, the opposite two surfaces of the first floating plate 212 can contact the inner wall of the mounting hole 2113.

[0086] In other embodiments, along the second floating direction Y, there is a gap between the first floating plate 212 and the inner wall of the assembly hole 2113, and gaps are also provided between the opposite two surfaces of the first floating plate 212 and the inner wall of the assembly hole 2113. Along the first direction X, the opposite two surfaces of the first floating plate 212 can contact the inner wall of the assembly hole 2113.

[0087] In some embodiments, a limiting groove 2114 is provided on the side of the fixed plate 2111 facing the pressure plate 2112, and 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 on the periphery of the first floating plate 212. The limiting protrusion 2121 is inserted into the limiting groove 2114, and the limiting protrusion 2121 can abut against the fixed plate 2111 and the pressure plate 2112. Thus, the relative movement of the first floating plate 212 and the fixed plate assembly 211 parallel to the third floating direction Z can be restricted. In addition, an annular second gap 2172 is left between the limiting protrusion 2121 and the inner wall of the limiting groove 2114 facing the assembly hole 2113 to avoid hindering the floating of the first floating plate 212 in the first floating direction X and the second floating direction Y.

[0088] In other embodiments, along the first floating direction X, the opposing side surfaces of the limiting protrusion 2121 may have a gap with the inner wall of the limiting groove 2114 facing the assembly hole 2113. Along the second floating direction Y, the opposing side surfaces of the limiting protrusion 2121 may contact the inner wall of the limiting groove 2114 facing the assembly hole 2113.

[0089] In other embodiments, along the second floating direction Y, the opposing side surfaces of the limiting protrusion 2121 may have a gap with the inner wall of the limiting groove 2114 facing the assembly hole 2113. Along the first floating direction X, the opposing side surfaces of the limiting protrusion 2121 may contact the inner wall of the limiting groove 2114 facing the assembly hole 2113.

[0090] In some embodiments, the first floating plate 212 may be a right-angled quadrilateral plate structure. One pair of sides of the first floating plate 212 may be parallel to the first floating direction X, and the other pair of sides of the first floating plate 212 may be parallel to the second floating direction Y.

[0091] In some embodiments, a plurality of first elastic elements 213 and a plurality of second elastic elements 214 may be disposed on the side of the fixing plate 2111 away from the pressure plate 2112.

[0092] In this embodiment, multiple first elastic elements 213 are symmetrically arranged on opposite sides of the first floating plate 212, and these sides are parallel to the second floating direction Y. The elastic direction of the first elastic element 213 is parallel to the first floating direction X. One end of the first elastic element 213 is fixedly connected to the fixed plate 2111, and the other end of the first elastic element 213 is fixedly connected to the first floating plate 212. Thus, when the floating mechanism 200 is not subjected to external force, the first floating plate 212 can remain balanced in the first floating direction X under the cooperative action of the multiple first elastic elements 213.

[0093] In other embodiments, a plurality of first elastic elements 213 may also be non-uniformly distributed on opposite sides of the first floating plate 212.

[0094] In this embodiment, one end of the first elastic member 213 can be fixedly connected to the fixed plate 2111 via the first hook 215, and the other end of the first elastic member 213 can be fixedly connected to the first floating plate 212 via the second hook 216.

[0095] Specifically, the first hook 215 can be fixedly connected to the fixed plate 2111 by means of screwing or welding. One end of the first elastic member 213 can be hooked onto the first hook 215. The end of the first hook 215 away from the fixed plate 2111 can be provided with a first limiting edge 2151, which can prevent the first elastic member 213 from detaching from the first hook 215 along the axial direction of the first hook 215. One end of the second hook 216 can be fixedly connected to the first floating plate 212 by means of screwing or welding. The other end of the first elastic member 213 can be hooked onto the second hook 216. The end of the second hook 216 away from the first floating plate 212 can be provided with a second limiting edge 2161, which can prevent the second elastic member 214 from detaching from the second hook 216 along the axial direction of the second hook 216.

[0096] In this embodiment, multiple second elastic elements 214 are symmetrically distributed on opposite sides of the first floating plate 212, and these sides are parallel to the first floating direction X. The elastic direction of the second elastic elements 214 is parallel to the second floating direction Y. One end of the second elastic element 214 is fixedly connected to the fixed plate 2111, and the other end of the second elastic element 214 is fixedly connected to the first floating plate 212. Thus, when the floating mechanism 200 is not subjected to external force, the first floating plate 212 can remain balanced in the second floating direction Y under the cooperative action of the multiple second elastic elements 214.

[0097] In other embodiments, a plurality of second elastic elements 214 may also be non-uniformly distributed on opposite sides of the first floating plate 212.

[0098] In this embodiment, one end of the second elastic element 214 can be fixedly connected to the fixed plate 2111 via the first hook 215, and the other end of the second elastic element 214 can be fixedly connected to the first floating plate 212 via the second hook 216. In this embodiment, the connection method of the second elastic element 214 can be similar to the connection method of the first elastic element 213, and will not be described again here.

[0099] In the embodiments, both the first elastic element 213 and the second elastic element 214 can be springs.

[0100] In other embodiments, the first elastic element 213 and the second elastic element 214 may be selected from structures such as elastic ropes or spring sheets.

[0101] In some embodiments, the second floating assembly 220 includes a guide rod 221, a third elastic element 222, and a second floating plate 223. The guide rod 221 passes through the first floating plate 212 along a third floating direction Z. The second floating plate 223 is fixedly connected to one end of the guide rod 221 by means of screws, welding, riveting, or snap-fitting, and the second floating plate 223 is located on the side of the pressure plate 2112 facing the first enclosure 110. A third limiting edge 2211 protrudes from the periphery of the end of the guide rod 221 away from the second floating plate 223, and the third limiting edge 2211 is located on the side of the first floating plate 212 opposite to the pressure plate 2112.

[0102] In this embodiment, the third elastic element 222 may be sleeved around the periphery of the guide rod 221, and the third elastic element 222 may abut between the first floating plate 212 and the second floating plate 223. When the floating mechanism 200 is not subjected to external force, the third elastic element 222 may be in a naturally extended state or a compressed state. In some embodiments, the third elastic element 222 may be a spring.

[0103] In other embodiments, the third elastic element 222 may also be a flexible column or a spring sheet.

[0104] In the embodiments, the guide rod 221 and the third elastic element 222 can be configured as one, two, or three pairs as needed.

[0105] In this embodiment, the first connector 300 can be fixedly installed on the side of the second floating plate 223 facing the first enclosure plate 110. In some embodiments, the first connector 300 can be a connector with its own guide post.

[0106] In some embodiments, the second floating assembly 220 further includes a first limiting member 224. The first limiting member 224 may be a limiting post or a limiting block, etc. The first limiting member 224 may be fixedly connected to the side of the first floating plate 212 facing the second floating plate 223 by means of screw connection or welding, and the first limiting member 224 is located on the floating path of the second floating plate 223. Thus, under the cooperative action of the first limiting member 224 and the third limiting edge 2211, the floating stroke of the second floating plate 223 can be limited, ensuring that the first connector 300 and the second connector 2200 can be smoothly inserted.

[0107] In other embodiments, the floating mechanism 200 may also be made of flexible blocks such as silicone, thermoplastic elastomer (TPE), thermoplastic polyurethane elastomer (TPU), or rubber, which can achieve floating in the first floating direction X, the second floating direction Y, and the third floating direction Z through the elastic deformation of the flexible blocks.

[0108] 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 slider 421, a guide 430, a fourth elastic member 441, a pin 451, a fifth elastic member 442, and a drive member 422.

[0109] One side of the support frame 410 is fixedly connected to a second enclosure 120 opposite to the conductive spring sheet 150 by means of bolts, adhesive, or snap-fit, and is located on the side of the second enclosure 120 away from the receiving cavity 101. The support frame 410 has a mounting cavity 411, a third opening 412, and a second opening 413, and the mounting cavity 411 can communicate with the third opening 412 and the second opening 413. In this embodiment, the third opening 412 can be arranged 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 arranged along the second floating direction Y. In addition, the support frame 410 is also provided with a second clearance hole 414 arranged along the first floating direction X, and the second clearance hole 414 communicates with the mounting cavity 411.

[0110] In some embodiments, one end of the guide member 430 is housed in the mounting cavity 411 and can be fixedly connected to the support frame 410 by means of bolts or adhesive. The other end of the guide member 430 can pass through the second opening 413 along the second floating direction Y and can protrude from the side of the support frame 410 facing the second enclosure 120. In some embodiments, the end of the guide member 430 that protrudes from the second opening 413 can pass through the second enclosure 120. And the end face of the guide member 430 near the second enclosure 120 can be flush with or slightly lower than the surface of the second enclosure 120 facing the receiving cavity 101. In addition, the guide member 430 also has 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, and the notch 432 can be disposed away from the second opening 413. In this embodiment, the second enclosure 120 may have a communicating hole 121 communicating with the accommodating cavity 101. The axial direction of the communicating hole 121 may be perpendicular to the direction from the first opening 102 to the first enclosure 110, and the axial direction of the first communicating hole 121 may be perpendicular to the third floating direction Z. In some embodiments, the axial direction of the communicating hole 121 may be parallel to the second floating direction Y.

[0111] In other embodiments, the locking mechanism 400 may be installed on the side of a third enclosure 130 away from the receiving cavity 101, and correspondingly, 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.

[0112] In some embodiments, the slider 421 is slidably disposed within the mounting cavity 411 along the third floating direction Z and is located on the side of the guide 430 facing the third opening 412. Additionally, the side of the slider 421 facing away from the second opening 413 may be configured with two spaced-apart sliding surfaces 4211, and the two sliding surfaces 4211 may be on the same plane. In some embodiments, the sliding surfaces 4211 may be inclined relative to the third floating direction Z. Specifically, the sliding surfaces 4211 may gradually tilt towards the second opening 413 from the end near the third opening 412 to the end away from the third opening 412.

[0113] In this embodiment, the drive member 422 may be mounted on the side of the support frame 410 facing the second enclosure 120. The output shaft of the drive member 422 may pass through the third opening 412 and abut against the slider 421. The drive member 422 may be used to drive the slider 421 to move toward the guide member 430. In some embodiments, the drive member 422 may be an electric push rod.

[0114] In other embodiments, the drive element 422 may also be a structure such as a cylinder or an electric cylinder.

[0115] In some embodiments, the fourth elastic member 441 may be arranged along the third floating direction Z and disposed between the guide member 430 and the slider 421. When the fourth elastic member 441 is in a compressed state, it can apply an elastic force to the slider 421, causing the slider 421 to move away from the guide member 430. In some embodiments, the fourth elastic member 441 may be a spring.

[0116] In some embodiments, both the pin 451 and the fifth elastic member 442 are disposed in the mounting hole 431. The pin 451 is slidably disposed in the mounting hole 431 along the second floating direction Y, and one end of the pin 451 is retractable relative to the end of the mounting hole 431 facing the guide member 430. When the end of the pin 451 extending relative to the mounting hole 431 facing the second enclosure 120 protrudes, the pin 451 may protrude relative to the side of the second enclosure 120 facing the receiving cavity 101.

[0117] In this embodiment, the fifth elastic member 442 may also be disposed along the second floating direction Y and located between the pin 451 and the inner wall of the mounting cavity 411. One end of the fifth elastic member 442 may abut against an inner wall of the mounting cavity 411 opposite to the second opening 413, and the other end of the fifth elastic member 442 may abut against the pin 451. In this embodiment, when the fifth elastic member 442 is in a compressed state, the fifth elastic member 442 may be used to drive the pin 451 to move toward the second enclosure 120. In some embodiments, the fifth elastic member 442 may be a spring.

[0118] In some embodiments, the pin 451 is rotatably connected to two symmetrical rolling elements 452 on one end circumferentially facing the fifth elastic element 442. The rotation axis of the rolling elements 452 may be parallel to the first floating direction X. In addition, the rolling elements 452 may pass through the notch 432, and the two rolling elements 452 may abut against the two sliding surfaces 4211 on the slider 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.

[0119] 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 by means of bolts or the like. In the embodiments, the blocking member 460 can be used to restrict the sliding member 421 from sliding out of the third opening 412, and the blocking member 460 has a connection port 461 communicating with the third opening 412, through which the output shaft of the driving member 422 can pass and abut against the sliding member 421.

[0120] In some embodiments, a Hall sensor 471 is further provided at the bottom of the support frame 410. The Hall sensor 471 is positioned close to the guide member 430 relative to the third opening 412. The Hall sensor 471 is electrically connected to the drive member 422. A magnetic member 472 cooperating with the Hall sensor 471 is provided on the slider 421. The slider 421 has a preset position. When the slider 421 is in the preset position, the end face of the pin 451 facing away from the fifth elastic member 442 is flush with the side surface of the guide strip 140 on the second enclosure 120 where the locking mechanism 400 is located, facing the receiving cavity 101. In the embodiment, when the drive member 422 drives the slider 421 to slide to the preset position, the magnetic member 472 triggers the Hall sensor 471, and the Hall sensor 471 triggers the drive member 422 to stop working.

[0121] In some embodiments, the locking mechanism 400 further includes a grip 480. The grip 480 may pass through the second clearance hole 414 along the first floating direction X and extend into the mounting cavity 411 to connect with the slider 421. During use, the operator can apply force to the slider 421 through the grip 480, which can move the slider 421 toward or away from the guide member 430.

[0122] During use, when it is necessary to install the battery 2000 into the battery compartment 1000, the drive unit 422 can be activated, causing the sliding member 421 to press against the fourth elastic member 441 and move towards the guide member 430. Under the pressing action of the sliding surface 4211, the rolling member 452 can move away from the second opening 413, and the pin 451 can press against the fifth elastic member 442 under the drive of the rolling member 452, and move relative to the side of the second enclosure 120 away from the receiving cavity 101. When the pin 451 moves into position, the magnetic member 472 can act on the Hall sensor 471, which can control the drive unit 422 to stop working. After that, the battery 2000 can be installed in the battery compartment 1000. For example, when the end face of the pin 451 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 receiving cavity 101, it can be recorded that the pin 451 has moved into position.

[0123] After the battery 2000 is installed in place, the drive unit 422 can be activated to retract its output shaft. The sliding member 421 can move away from the guide member 430 under the elastic force of the fourth elastic member 441, thereby releasing the sliding surface 4211 from pressing against the rolling member 452. The pin 451 can protrude from the side of the second enclosure 120 facing the receiving cavity 101 under the elastic force of the fifth elastic member 442 and be inserted into the pin hole 2110 on the battery 2000 to achieve locking between the battery 2000 and the battery compartment 1000.

[0124] like Figure 1 , Figure 14 and Figure 15 As shown, the embodiment also provides a power supply device, including a battery 2000 and a battery compartment 1000 provided in the embodiment.

[0125] The battery 2000 may include a battery body 2100 and a second connector 2200 protruding from one end of the battery body 2100, which can be electrically connected to the battery body 2100. When the battery 2000 is installed in the battery compartment 1000, the second connector 2200 can be inserted into the first connector 300 to form an electrical connection, enabling the transmission of electrical energy and signals. In this embodiment, the second connector 2200 may be a connector with a guide hole and is adapted to the first connector 300.

[0126] In some embodiments, a second limiting member 2300 protrudes from one end of the battery body 2100 facing the second connector 2200. The second limiting member 2300 may be a limiting block or a limiting post. When the second connector 2200 is inserted into the first connector 300, the second limiting member 2300 abuts against the buffer pad 160, which can limit the insertion depth of the second connector 2200 and the first connector 300, avoid overshoot, and reduce the possibility of damage to the first connector 300 and the second connector 2200.

[0127] In addition, the end of the battery body 2100 facing the second connector 2200 is also provided with two opposing second guide ramps 2120. The second guide ramps 2120 gradually slope away from the end near the second connector 2200 to the end away from the second connector 2200, providing a guiding function when the battery 2000 is installed in the battery compartment 1000, further improving the installation efficiency of the battery 2000.

[0128] In some embodiments, the battery body 2100 is further provided with a pin hole 2110 adapted to the pin 451. When the battery 2000 and the battery compartment 1000 are installed in place, the pin 451 in the battery compartment 1000 can be inserted into the pin hole 2110 on the battery body 2100 to lock the battery 2000 and prevent the battery 2000 from arbitrarily leaving the battery compartment 1000.

[0129] In some embodiments, a handle 2400 is also provided on the side of the battery body 2100 opposite to the second connector 2200, which facilitates the user to install and remove the battery 2000.

[0130] When installing the battery 2000 into the battery compartment 1000, the battery 2000 can be held by the handle 2400 by a worker or a robotic arm, with the end of the battery 2000 equipped with the second connector 2200 facing the battery compartment 1000. Under the action of the guide bar 140 and the second guide ramp 2120, the battery 2000 can be smoothly inserted into the receiving cavity 101 of the battery compartment 1000. Afterwards, the battery 2000 can contact the conductive spring 150 in the battery compartment 1000, and the guide post on the first connector 300 can gradually pass through the guide hole of the second connector 2200. The first floating assembly 210 can provide the first connector 300 with floating in the first floating direction X and the second floating direction Y, so that the first connector 300 and the second connector 2200 are accurately aligned. The battery 2000 is further pushed into the battery compartment 1000. Under the action of the second floating component 220, the first connector 300 can float in the third floating direction Z. After the battery 2000 is installed in place, the first connector 300 can be inserted into the second connector 2200 to form an electrical connection. Then, the pin 451 of the locking mechanism 400 can be inserted into the pin hole 2110 of the battery 2000 to lock the battery 2000.

[0131] The steps for removing battery 2000 are the reverse of the steps for installing battery 2000.

[0132] The embodiment also provides a robot, which may include the battery compartment 1000 and the battery 2000 provided in the embodiment. The battery 2000 is detachably installed in the battery compartment 1000, and the second connector 2200 in the battery 2000 can be plugged and unplugged into the first connector 300 in the battery compartment 1000.
