Description

Technical Field

[0001] This disclosure relates to the field of battery device technology, and more particularly to a battery device and a robot. Background Technology

[0002] With the expanding applications of humanoid robots, the installation design of battery packs faces a key dilemma. On the one hand, the multi-directional vibrations and impacts experienced by humanoid robots during dynamic movement require highly reliable mechanical fixation of the battery pack; on the other hand, for efficiency reasons, the battery pack needs to support frequent and rapid assembly and disassembly. While the multi-point fixing structure commonly used in the industry improves connection stability, it also complicates the assembly and disassembly process.

[0003] Furthermore, to meet the requirements of long battery life, battery devices are typically quite heavy. During assembly and disassembly, users must simultaneously align and secure multiple independent connection points under continuous load. This not only increases the user's physical burden but also reduces the accuracy and efficiency of the connection process, further impacting the ease of assembly. Summary of the Invention

[0004] To address at least one of the aforementioned and other technical problems in the prior art, this disclosure provides a battery device and a robot. The mounting part includes at least two locking tongues and an operating component. The operating component is linked with the at least two locking tongues to synchronously move the at least two locking tongues between a first position and a second position, thereby facilitating the user's disassembly and assembly operations.

[0005] This disclosure provides a battery device, comprising: a main body having a battery cell; a mounting portion disposed on the main body, the mounting portion including: at least two latches having a first position located within the mounting portion and a second position at least partially exposed outside the mounting portion; an operating member for a user to remove the battery device, and the operating member being configured to interact with the at least two latches to adjust the at least two latches between the first position and the second position; when the latches are in the first position, the battery device is separated from an external robot body, and when the latches are in the second position, the battery device remains attached to the robot body.

[0006] According to an embodiment of the present disclosure, the mounting portion further includes: a housing connected to the main body portion, the housing defining the outer contour of the mounting portion; when the latch is in the first position, the latch is located inside the housing, and when the latch is in the second position, at least a portion of the latch extends out of the housing.

[0007] According to an embodiment of this disclosure, the mounting portion further includes: a rotating member rotatably disposed within the housing; at least two connecting rods centrally symmetrically disposed on both sides of the rotating member, one end of each connecting rod being pivotally connected to the rotating member and the other end being pivotally connected to one of the latches, the connecting rods being configured to convert the angular displacement of the rotating member about its axis into the linear displacement of the latch, so that the latch moves between the first position and the second position; and a reset member configured to apply a restoring force to the latch from the first position toward the second position, so that the latch is reset to the second position.

[0008] According to an embodiment of this disclosure, the reset member includes a first elastic member disposed between the latch and the housing, wherein the elastic force applied by the first elastic member to the latch serves as the restoring force.

[0009] According to an embodiment of the present disclosure, the first elastic element includes a compression spring, one end of which abuts against the latch and the other end of which abuts against a protrusion formed in the housing.

[0010] According to an embodiment of this disclosure, the operating member is configured as a U-shaped structure, including a gripping end located in the middle and connecting ends located on both sides of the gripping end, the connecting ends being pivotally connected to the housing; the operating member has a first posture and a second posture, when the operating member is in the first posture, a first gap is formed between the gripping end and the housing, and when the operating member is in the second posture, a second gap is formed between the gripping end and the housing, the first gap being greater than the second gap.

[0011] According to an embodiment of this disclosure, the mounting part further includes a rotating shaft, with each of the two axial ends of the rotating shaft passing through one of the connecting ends. The operating member is connected to the rotating member via the rotating shaft so that the operating member and the rotating member rotate synchronously. The rotation plane of the operating member is parallel to the rotation plane of the rotating member.

[0012] According to an embodiment of this disclosure, the battery device further includes a second elastic member disposed in the housing and configured to apply pressure to the operating member from the first posture to the second posture.

[0013] According to an embodiment of this disclosure, the second elastic member includes a torsion spring, the first arm of which abuts against the housing, and the second arm of which abuts against the rotating member.

[0014] This disclosure also provides a robot, including: a robot body having a battery compartment with a groove provided therein for engaging with the latch; and a battery device detachably disposed in the battery compartment, wherein when the latch of the battery device is in a second position, the battery device is retained in the battery compartment and electrically connected to the robot body.

[0015] According to the illustrative embodiments of the present disclosure, the battery device includes a main body accommodating battery cells and a mounting portion for mechanical coupling with the robot body. The mounting portion is equipped with an operating element and at least two locking tongues. By operating the operating element, the user can drive all locking tongues to move synchronously between a first position and a second position, thereby achieving rapid connection or separation of the battery device from the robot body. A single operation enables multi-point synchronous locking or releasing, simplifying the assembly and disassembly process. Furthermore, the operating element also has a dual function: firstly, it serves as the force application point for the user to lift the battery device, facilitating pushing and positioning during installation and lifting and moving during disassembly; secondly, it serves as the operating structure for controlling the movement of the locking tongues, allowing the user to complete the linkage control of the locking mechanism through the same operating element. This allows the operating element to simultaneously perform the functions of holding and manipulating, facilitating one-handed operation and further improving the convenience of the battery device during assembly and disassembly.

[0026] To make the objectives, technical solutions, and advantages of this disclosure clearer, the following detailed description is provided in conjunction with specific embodiments and the accompanying drawings.

[0027] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit this disclosure.

Similarly, when using expressions such as "at least one of A, B, or C," the meaning should generally be interpreted according to the understanding of someone skilled in the art. For example, "a system having at least one of A, B, or C" should include, but is not limited to, systems having A alone, having B alone, having C alone, having A and B, having A and C, having B and C, and / or having A, B, and C.

[0030] It should also be noted that the directional terms mentioned in the embodiments, such as "up," "down," "front," "back," "left," and "right," are only for reference in the accompanying drawings and are not intended to limit the scope of protection of this disclosure. Throughout the drawings, the same elements are represented by the same or similar reference numerals. Conventional structures or constructions will be omitted where they may cause confusion in understanding this disclosure.

[0031] As humanoid robots increasingly integrate into daily environments and undertake diverse tasks, the design and installation of their battery packs face numerous engineering challenges. For different usage scenarios, robots need to move stably on stairs, ramps, congested streets, and complex indoor surfaces. These dynamic conditions not only generate multi-directional, high-frequency vibrations and impacts but also place higher demands on the reliability of connections between internal components within the robot body. As the robot's core energy module, the battery pack must remain stable in such environments to maintain effective electrical connections and prevent potential malfunctions such as power outages, arcing, or even mechanical damage.

[0032] Meanwhile, to ensure continuous robot operation, batteries must support frequent, rapid replacement or convenient charging, meaning their assembly and disassembly operations need to be extremely simplified and efficient. Existing mainstream technologies exhibit significant shortcomings under these dual objectives. While screw fastening provides a reliable mechanical connection, its assembly and disassembly process relies on tools, involves cumbersome steps, and repeated tightening can lead to thread wear. Over time, the locking force decreases, and the user experience is poor in scenarios requiring frequent assembly and disassembly. On the other hand, while simple snap-fit ​​or plug-in structures improve operational convenience, their inherent elastic locking mechanism is prone to fatigue and loosening under continuous vibration, posing a potential risk of accidental disengagement and failing to meet high reliability requirements.

[0033] To improve connection reliability, related technologies have further adopted a multi-point locking connection method, which involves setting multiple connection points between the battery device and the robot body. However, this introduces new problems: in actual operation, users must align and operate multiple locking points (such as multiple clips) one by one. This process is not only cumbersome and time-consuming, but more importantly, it is difficult to achieve precise synchronization of locking and releasing at each point. Uneven force can easily lead to component jamming, accelerated wear, or seal failure. In addition, multi-point operation requires high installation accuracy and consistency of user operation. In rushed or inconvenient on-site environments, individual points are prone to not being fully locked, thus creating potential safety hazards.

[0034] In view of this, how to provide a battery device and robot that are easy to install and remove and can form a reliable connection with the robot body has become an urgent technical problem to be solved.

[0035] Figure 1 A perspective view of a battery device according to an illustrative embodiment of the present disclosure is shown. Figure 2 yes Figure 1 The battery device shown is a front view.

[0036] This disclosure provides a battery device 100, with reference to... Figure 1 and Figure 2As shown, the system includes a main body 110 and a mounting portion 120. The main body 110 has a battery cell. The mounting portion 120 is disposed on the main body 110 and includes at least two locking tongues 121 and an operating member 123. The at least two locking tongues 121 have a first position located within the mounting portion 120 and a second position at least partially exposed outside the mounting portion 120. The operating member 123 is used by a user to remove the battery device 100, and the operating member 123 is configured to interact with the at least two locking tongues 121 to adjust the at least two locking tongues 121 between the first position and the second position. When the locking tongues 121 are in the first position, the battery device 100 is separated from the external robot body 200; when the locking tongues 121 are in the second position, the battery device 100 is held within the robot body 200.

[0037] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the main body 110 of the battery device 100 includes battery cells. These battery cells include, but are not limited to, lithium-ion batteries, polymer batteries (such as lithium polymer batteries), lithium iron phosphate batteries, solid-state batteries, and any other type of battery cell suitable for powering the robot body 200. Furthermore, the main body 110 also includes a battery management system (BMS), which is electrically connected to the battery cells and is used to monitor and control the charging and discharging process of the battery. It provides at least one of the following protections: overcharge protection (preventing overcharging of the battery cells), over-discharge protection (preventing over-discharging of the battery cells), overcurrent protection (limiting current output to prevent short circuits and / or overloads), and over-temperature protection (preventing excessively high battery cell temperatures and stopping charging and discharging in a timely manner to prevent thermal runaway).

[0038] It should be noted that the battery cells and battery management modules configured in the battery device 100 are not the focus of this disclosure. Any battery cells and battery management modules that can be used in the battery device 100 and provide power and / or charge at least some of the mechanisms of the robot body 200 may be selected for application. Therefore, they will not be elaborated on in detail.

[0039] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the outer contour of the main body 110 includes, but is not limited to, a box-like structure configured as a generally cubic shape, in which the battery cells are disposed.

[0040] Furthermore, the battery device 100 is also provided with an electrical connector for electrically connecting the main body 110 to the robot body 200, for example, a female connector, and correspondingly, the robot body 200 is provided with a male connector. In addition, to dissipate heat during the charging and discharging process of the battery cell, heat dissipation holes (not shown in the figure) may be provided on its surface. These heat dissipation holes can be active heat dissipation holes equipped with cooling devices such as fans, or passive heat dissipation holes. It should be understood that the embodiments of this disclosure are not limited thereto.

[0041] For example, the battery device 100 and / or the main body 110 may be configured as a cylindrical, cylindrical, polygonal, or any other solid structure, specifically to meet the spatial structure requirements of the battery compartment provided by the robot body 200.

[0042] In some illustrative embodiments, reference is made to Figure 1 and Figure 2 As shown, the mounting part 120 is fixedly connected to the main body part 110, and the connection method includes, but is not limited to, screw connection, bolt connection, snap-fit ​​connection, interference fit connection, and any other connection method. That is to say, the mounting part 120 and the main body part 110 can be regarded as a whole for assembly with the robot body 200. Furthermore, when the battery device 100 is assembled to the robot body 200 (or other electronic devices), the mounting part 120 connects the main body part 110 to the robot body 200.

[0043] In some illustrative embodiments, when the battery device 100 is installed on the robot body 200, the locking tongue 121 of the mounting portion 120 is in a second position, so that the battery device 100 is physically connected to the robot body 200. Simultaneously, the main body 110 of the battery device 100 also forms a stable electrical connection with the robot body 200. Furthermore, the operating member 123 of the mounting portion 120 is exposed on the outer surface of the robot body 200, allowing the user to operate (e.g., rotate, pull, etc.) to switch the locking tongue 121 between the second and first positions. This allows the battery device 100 to be completely removed from the robot body 200 for charging and other operations. Additionally, when installing the battery device 100, the user can push the battery device 100 into the battery compartment of the robot body 200 using the operating member 123, and when removing the battery, the user can use the operating member 123 to remove the battery device 100 from the battery compartment.

[0044] In the embodiments of this disclosure, the battery device 100 mainly consists of two parts: a main body 110 for housing the battery cells and a mounting part 120 for mechanical coupling with the robot body 200. The mounting part 120 includes an operating element 123 and at least two locking tongues 121. By applying an action (such as pulling, rotating, or pressing) to the operating element 123, the user can drive the internal linkage mechanism to synchronously move all locking tongues 121 between a first position (retracted into the mounting part 120) and a second position (at least partially extended out of the mounting part 120). When all locking tongues 121 synchronously move to the second position, they engage with the grooves 210 on the robot body 200, achieving a secure lock and electrical connection of the battery device 100; when the locking tongues 121 synchronously retract to the first position, all mechanical coupling points are synchronously released, and the battery device 100 can be safely separated from the robot body 200. Thus, the user only needs one continuous operation step to control the synchronous locking or releasing of all connection points, thereby significantly simplifying the assembly and disassembly operations.

[0045] Furthermore, the operating component 123 itself serves two functions. First, it is designed with an ergonomic force and grip structure, serving as the primary force point for the user to extract, move, and push the battery device 100 during assembly and disassembly. Second, it acts as a control structure linked to multiple locking bolts 121, allowing the user to directly control the synchronous movement of all locking bolts 121 by operating this component. This integrates the gripping and unlocking of the battery device 100 into a single design, meaning that when installing the battery, the user can use the same hand action to move, align, and lock it; during disassembly, the user can simultaneously unlock and remove the battery device 100 by pulling the operating component 123 in a continuous motion. This enables the battery device 100 to not only support efficient one-handed operation but also eliminates the inconvenience of the user having to perform multiple complex operations while under load.

[0046] According to embodiments of this disclosure, referring to Figure 1 and Figure 2 As shown, the mounting portion 120 also includes a housing 122. The housing 122 is connected to the main body portion 110 and defines the outer contour of the mounting portion 120. At least two latches 121 are retractably disposed on the housing 122.

[0047] In some illustrative embodiments, reference is made to Figure 1 and Figure 2As shown, the mounting portion 120 includes a housing 122, which is, but is not limited to, configured as a cubic structure for mounting to one end of the main body 110. Of course, the housing 122 can also be configured with other structures to conform to the shape of the main body 110. Specifically, the outer surface of the housing 122 defines the outer contour of the mounting portion 120. Furthermore, the housing 122 has through holes on opposite sides for the movement of the latches 121. When the two latches 121 are in a first position, the latches 121 are entirely within the through holes. When the latches 121 are in a second position, the end of the latches 121 used for connection with the robot body 200 (which can be understood as the movable end) extends out of the through holes to form a connection with the robot body 200.

[0048] In some other illustrative embodiments, not shown in the figures, the mounting portion 120 includes at least three latches 121, which are centrally symmetrically arranged on the operating member 123.

[0049] In some illustrative embodiments, specifically in cases where the mounting portion 120 and / or the main body 110 are configured as a cylindrical structure, the mounting portion 120 may have three through holes along its circumference. Correspondingly, the mounting portion 120 is also configured with locking tongues 121 corresponding to the number of through holes, so that the three locking tongues 121 can move synchronously between a first position and a second position to form three connection points with the robot body 200. Of course, the number of locking tongues 121 configured in the mounting portion 120 can also be 4, 5, 6, or any other arbitrary number.

[0050] Figure 3 yes Figure 2 The diagram shows the structure of the operating component, rotating component, and locking tongue. Figure 4 yes Figure 2 A partial cross-sectional view of the battery device shown along direction AA.

[0051] According to embodiments of this disclosure, referring to Figure 3 and Figure 4 As shown, the mounting portion 120 also includes a rotating member 124, at least two connecting rods 125, and a resetting member. The rotating member 124 is rotatably disposed within the housing 122. At least two connecting rods 125 are centrally symmetrically disposed on both sides of the rotating member 124. One end of each connecting rod 125 is pivotally connected to the rotating member 124, and the other end is pivotally connected to a latch 121. The connecting rods 125 are configured to convert the angular displacement of the rotating member 124 about its axis into a linear displacement of the latch 121, thereby moving the latch 121 between a first position and a second position. The resetting member is configured to apply a restoring force to the latch 121 from the first position toward the second position, thereby resetting the latch 121 to the second position.

[0052] According to embodiments of this disclosure, referring to Figure 3 and Figure 4 As shown, the reset member includes a first elastic element 126. The first elastic element 126 is disposed between the latch 121 and the housing 122, and the elastic force applied by the first elastic element 126 to the latch 121 serves as the restoring force.

[0053] According to embodiments of this disclosure, referring to Figure 3 and Figure 4 As shown, the first elastic element 126 includes a compression spring, one end of which abuts against the locking tongue 121, and the other end of which abuts against the protrusion 1221 formed in the housing 122.

[0054] In some illustrative embodiments, reference is made to Figure 3 and Figure 4 As shown, within the mounting space defined inside the housing 122 of the mounting part 120, the mounting part 120 further includes a rotating member 124, at least two connecting rods 125, and a first elastic member 126 serving as a reset member. Specifically, the rotating member 124 is rotatably mounted within the housing 122 and can be driven to rotate about its axis by an operating member 123 (such as a knob or lever). At least two connecting rods 125 are arranged symmetrically on both sides of the rotating member 124. One end of each connecting rod 125 is pivotally connected to an eccentric position on the rotating member 124, and the other end is pivotally connected to the corresponding latch 121. Thus, when the rotating member 124 rotates under the drive of the operating member 123, its eccentric motion is converted into a linear displacement of the latch 121 via the connecting rods 125, thereby enabling all latches 121 to move synchronously between a second position (extending out of the mounting part 120) and a first position (retracted into the mounting part 120).

[0055] Furthermore, the first elastic element 126 is used to reset the latch 121 from the first position to the second position. The first elastic element 126 includes, but is not limited to, a compression spring. Specifically, one end of the compression spring abuts against the inner side of the latch 121, and the other end abuts against the protrusion 1221 formed on the inner side of the housing 122. In its natural state, the first elastic element 126 applies an elastic force to the latch 121 toward the second position, so that the latch 121 always maintains an outward extension tendency, thereby ensuring that the battery device 100 can stably maintain a mechanical coupling state with the robot body 200 when not operated (which may be operated by the operating element 123). When the user drives the rotating element 124 to rotate through the operating element 123, causing the latch 121 to retract to the first position against the spring force, the battery device 100 can be safely separated from the robot body 200; and after the operating element 123 is released, the latch 121 can automatically reset to the second position (i.e., the extended state) under the action of the elastic force provided by the compression spring. It should be understood that the embodiments disclosed herein are not limited thereto.

[0056] For example, in addition to a compression spring, the first elastic element 126 can also have a tension spring provided on the side of the latch 121 opposite to the protrusion 1221, so that the elastic force generated by the tensile deformation serves as the restoring force. Similarly, a torsion spring can be arranged outside the axis of the operating member 123, thereby providing a restoring force by driving the rotation of the operating member 123.

[0057] Alternatively, in addition to using the first elastic element 126 as the reset element, the attraction between magnetic magnets can also be used as the restoring force. Specifically, one magnet can be placed at the end of the latch 121 that extends through the housing 122, and another magnet can be placed inside the corresponding robot body 200, thereby keeping the latch 121 in the second position.

[0058] In this implementation, the user drives the rotating member 124 by rotating the operating member 123, and the rotational motion is synchronously converted into linear motion of all locking tongues 121 via symmetrically arranged connecting rods 125, allowing multiple connection points to be locked or released simultaneously. This mechanical linkage mechanism structurally eliminates the need for separate sequential operation of each connection point in related technologies, thereby simplifying the operation steps and improving assembly and disassembly efficiency. In addition, the first elastic member 126, composed of a compression spring, continuously applies a pushing force towards the locked position to the locking tongues 121. This elastic reset mechanism ensures that the locking tongues 121 automatically remain in the second position of the extended mounting portion 120 in the non-operating state, thereby providing a stable mechanical holding force for the battery device 100. This enhances the reliability of the connection under dynamic loads and helps resist vibrations and impacts generated during robot movement.

[0059] Figure 5 yes Figure 2 A partial cross-sectional view of the battery device shown in the BB direction.

[0060] According to embodiments of this disclosure, referring to Figures 3 to 5 As shown, the operating member 123 is configured with a U-shaped structure, including a gripping end located in the middle and connecting ends located on both sides of the gripping end. The connecting ends are pivotally connected to the housing 122. The operating member 123 has a first posture and a second posture. When the operating member 123 is in the first posture, a first gap is formed between the gripping end and the housing 122. When the operating member 123 is in the second posture, a second gap is formed between the gripping end and the housing 122. The first gap is greater than the second gap.

[0061] According to embodiments of this disclosure, referring to Figures 3 to 5 As shown, the mounting part 120 also includes a rotating shaft 128. Each of the two axial ends of the rotating shaft 128 passes through a connecting end. The operating member 123 is connected to the rotating member 124 via the rotating shaft 128, so that the operating member 123 and the rotating member 124 rotate synchronously. The plane of rotation of the operating member 123 is parallel to the plane of rotation of the rotating member 124.

[0062] In some illustrative embodiments, such as Figures 3 to 5 As shown, the operating member 123 is designed with a generally U-shaped structure, including a gripping end in the middle and connecting ends on both sides. The connecting ends on both sides are pivotally connected to the housing 122 via a rotating shaft 128 (e.g., bolts), so that the operating member 123 can switch between a first posture and a second posture around the rotating shaft 128.

[0063] Furthermore, the outer end face of the housing 122 is also provided with a receiving groove that matches the shape of the operating member 123. When the operating member 123 is in the second posture, its gripping end is received in the receiving groove, preventing it from protruding from the surface of the housing 122, thereby preventing interference with the user or surrounding movement. When the user grips the gripping end and flips the operating member 123 from the second posture outward to the first posture, the operating member 123 drives the rotating member 124 to rotate via the rotating shaft 128, and then drives the locking tongue 121 to move synchronously to the first position via the connecting rod 125. During this process, the user can remove the battery device 100 from the robot body 200 while lifting the operating member 123, realizing the disassembly operation. Conversely, when installing the battery device 100, the user can grip the operating member 123 in the first posture, push the battery device 100 into the installation position of the robot body 200, and then press the operating member 123 back to the second posture. At this time, with the assistance of the second elastic element 127 (described in the following embodiments), the rotating element 124 and the locking tongue 121 move synchronously to the second position, completing the mechanical locking and electrical connection between the battery device 100 and the robot body 200. This design integrates gripping, operation, and status indication, improving the continuity of operation and the efficiency of human-machine interaction.

[0064] According to embodiments of this disclosure, referring to Figures 3 to 5 As shown, it also includes a second elastic member 127. The second elastic member 127 is disposed in the housing 122 and is configured to apply pressure to the operating member 123 from the first posture to the second posture.

[0065] According to embodiments of this disclosure, referring to Figures 3 to 5 As shown, the second elastic element 127 includes a torsion spring, the first arm 1271 of which abuts against the housing 122, and the second arm 1272 of which abuts against the rotating element 124.

[0066] In some illustrative embodiments, such as Figure 5 As shown, the mounting portion 120 also includes a second elastic element 127, which may include, but is not limited to, a torsion spring. Specifically, the first arm 1271 of the torsion spring abuts against the inner wall of the housing 122, and the second arm 1272 abuts against the rotating member 124. The axial ends of the rotating shaft 128 pass through the connecting ends on both sides of the operating member 123 and are coaxially arranged with the center of the rotating member 124, thereby enabling the operating member 123 and the rotating member 124 to rotate synchronously, and their rotation planes remain parallel. Based on this, the second elastic element 127 continuously applies torque to the rotating member 124, which is transmitted to the operating member 123 through the rotating shaft 128, forming an elastic pressure that automatically returns it from an extended first posture to a retracted second posture.

[0067] In this implementation, the restoring torque provided by the second elastic element 127 ensures that the operating element 123 remains stably in the second posture when there is no external force, at which time the locking tongue 121 is in the extended locking state, thereby maintaining a reliable connection of the battery device 100 during non-operational phases. The rigid connection of the rotating shaft 128 enables direct synchronization between external operation and the movement of the internal locking tongue 121, effectively avoiding motion lag or jamming caused by transmission backlash. In addition, the elastic reset mechanism provides clear force feedback during operation and automatically restores the operating element 123 to the retracted position flush with the housing 122 after installation, allowing the user to determine the engagement relationship between the battery device 100 and the robot body 200 by observing the posture of the operating element 123. It should be understood that the embodiments of this disclosure are not limited thereto.

[0068] For example, in the embodiment where the operating member 123 and the rotating member 124 are coaxially arranged and linked, only one of the first elastic member 126 and the second elastic member 127 can be retained. That is, when the first elastic member 126 resets the latch to the second position, the rotating member 124 is also driven to rotate accordingly, thereby driving the operating member 123 to reset to the second posture; or, when the second elastic member 127 resets the operating member 123 to the second posture, the rotating member 124 is also driven to rotate accordingly, thereby resetting the latch to the second position.

[0069] Figure 6 A portion of a robot according to an illustrative embodiment of the present disclosure is shown.

[0070] This disclosure also provides a robot, referring to Figure 6 As shown, the system includes a robot body 200 and a battery device 100. The robot body 200 has a battery compartment with a groove 210 for engaging with a locking tongue 121. The battery device 100 is detachably disposed in the battery compartment. When the locking tongue 121 of the battery device 100 is in the second position, the battery device 100 is held within the battery compartment and electrically connected to the robot body 200.

[0071] In some illustrative embodiments, reference is made to Figure 6 As shown, the robot body 200 is provided with a battery compartment. Specifically, the inner wall of the battery compartment has grooves 210 that match the shape of the latches 121 at positions corresponding to the latches 121 on the battery device 100. The number, position, and orientation of these grooves 210 precisely correspond to the multiple latches 121 on the battery device 100.

[0072] In this implementation, when the battery device 100 is pushed into the battery compartment to a predetermined position, all locking tongues 121 are accurately aligned with the entrances of their respective grooves 210. At this time, the user releases the operating member 123, which is reset to a second posture under the action of the second elastic member 127. Simultaneously, each locking tongue 121 moves from the first position (retracted state) to the second position (extended state) under the action of the reset member. The extended ends of the locking tongues 121 then fully embed into the corresponding grooves 210 of the robot body 200, forming a rigid multi-point mechanical interlock. This embedding fit can not only withstand radial pull-out forces, but its special groove shape (such as L-shape or stepped shape) can also effectively resist shear forces and vibrations from all directions, thereby firmly anchoring the battery device 100 within the robot body 200.

[0073] Through the distributed rigid connection formed by multiple locking tongues 121 and grooves 210, the battery device 100 and the robot body 200 form a high-rigidity integral structure, which can effectively suppress relative displacement and micro-movements in complex motion scenarios, ensuring the continuous stability and safety of the power connection, and fundamentally avoiding power outages or poor contact caused by vibration. Secondly, in terms of operational efficiency and user experience, the entire installation process requires no tools. Only two intuitive actions, such as turning the operating part 123 and pushing in the battery device 100, are required to complete the mechanical locking and electrical connection in a short time (e.g., within a few seconds). Disassembly can be achieved by turning the operating part 123 in the opposite direction, which greatly improves the efficiency of battery device 100 replacement or charging maintenance, thereby meeting the needs of high-frequency and fast-paced applications.
