Abstract
Description
Technical Field
[0001] This utility model relates to the field of battery technology, specifically to a detachable battery assembly and a robot. Background Technology
[0002] Removable batteries are widely used in various portable devices, robots, and energy storage devices because they are easy to replace and maintain. To ensure the stability of the connection between the battery and the device, existing removable batteries usually need to be equipped with a locking mechanism to prevent accidental dislodgement. At the same time, they are also equipped with handles or other gripping parts to facilitate the handling of the battery.
[0003] However, in most commonly used removable batteries, the unlocking mechanism and the handle are often separate structures. Specifically, when removing the battery, the user must first operate the unlocking component separately (such as pressing the unlock button or moving the unlock lever) to release the battery from the device. After the lock is released, the user then holds the handle to remove the battery from the device. This design results in at least two independent steps in the battery removal process, increasing user complexity, extending replacement time, and causing noticeable jerking during the transition between unlocking and lifting, thus affecting the user experience.
[0004] Therefore, simplifying the disassembly process of removable batteries, improving the smoothness and continuity of unlocking and lifting actions, and reducing the user's operational burden have become urgent technical problems to be solved in this field. Utility Model Content
[0005] The purpose of this invention is to provide a detachable battery assembly and robot, which can effectively solve the problem that existing detachable batteries are complicated to remove when the battery needs to be taken out because the unlocking and lifting parts are set separately.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] A removable battery pack includes a housing and battery cells housed therein, the housing having a slidable latch having a locking end for locking engagement and a driven end;
[0008] A first reset mechanism is provided between the latch and the housing, which is used to drive the latch to reset to the initial locking position when the external force on the latch disappears.
[0009] The housing is also provided with an unlocking component, which includes an unlocking part that abuts against the driven end and a connecting end;
[0010] The connecting end is rotatably connected to a handle, which has the following functions: unlocked state: driving the unlocking component to push the driven end to unlock the locking end; and lifting state: moving the unlocked battery pack.
[0011] The housing is provided with a limiting structure to maintain the contact between the housing and the unlocking component in the lifting direction when the housing is in the lifting state.
[0012] In the aforementioned detachable battery assembly, the limiting structure includes a blocking plate fixedly connected to the housing, the blocking plate abutting against the locking tongue in the lifting direction, and the locking tongue abutting against the unlocking member in the lifting direction.
[0013] In the aforementioned detachable battery assembly, the unlocking member is provided with an abutment portion, and the limiting structure includes a limiting member located on the movement path of the abutment portion along the lifting direction.
[0014] In the aforementioned detachable battery assembly, the housing is provided with a limiting groove, the abutting part is a slider and is slidably disposed in the limiting groove, and the limiting member is the groove wall of the limiting groove along the lifting direction.
[0015] In the aforementioned detachable battery assembly, at least one of the driven end and the unlocking part is provided with a guide structure for converting the movement of the unlocking member in the lifting direction into the unlocking displacement of the locking tongue.
[0016] In one of the aforementioned detachable battery assemblies, the guide structure includes a guide ramp or a guide arc surface.
[0017] In the aforementioned detachable battery assembly, the housing is provided with a recess for storing the handle, and the recess has a through hole for the connecting end to extend out of the housing.
[0018] In the aforementioned detachable battery assembly, a second reset mechanism is provided between the unlocking component and the housing, and the second reset mechanism exerts a force on the unlocking component that is opposite to the lifting direction.
[0019] In the aforementioned removable battery assembly, the unlocking member has a through groove through which the locking end passes, and the unlocking part and the connecting end are located at opposite ends of the through groove.
[0020] A robot is also disclosed, including a battery placement cavity and a detachable battery pack as described in any of the above embodiments, wherein the side wall of the battery placement cavity is provided with a locking part adapted to the locking end.
[0021] Compared with the prior art, the advantages of this utility model are:
[0022] The handle and unlocking mechanism are connected by a rotating mechanism, allowing the handle to drive the unlocking mechanism to push the driven end of the latch when unlocked, thus unlocking the locking end. When pulled, it directly moves the battery pack. Unlike traditional designs where the unlocking mechanism and handle are operated separately, this design combines the previously independent unlocking and pulling steps, simplifying the battery removal process and reducing the number of steps. Thanks to the cooperation between the latch and the unlocking mechanism, the unlocking and pulling actions are seamlessly connected during handle operation. Users only need to operate the handle to complete unlocking and pulling sequentially, avoiding the interruption or jerking that can occur with separate steps in traditional designs, thus improving the user experience. The housing has a limiting structure that maintains contact between the housing and the unlocking mechanism in the pulling direction, ensuring stable force on the battery pack during lifting and preventing structural loosening from affecting the lifting effect, while also ensuring the overall structural reliability.
[0023] Furthermore, the limiting structure includes a baffle plate fixedly connected to the housing. The baffle plate abuts against the locking tongue in the lifting direction, and the locking tongue abuts against the unlocking component in the lifting direction. The baffle plate abuts against the locking tongue in the lifting direction, and the locking tongue abuts against the unlocking component, forming a force transmission chain of "unlocking component → locking tongue → baffle plate". This structural design ensures that when the handle is in the lifting state, the lifting force is stably transmitted to the baffle plate through the unlocking component and locking tongue, and then dispersed to the housing by the baffle plate. This ensures that the force on each component is balanced during the lifting process, avoids damage to a single component due to concentrated force, and improves the structural reliability of the battery pack during lifting.
[0024] Furthermore, the unlocking component is provided with an abutment portion, and the limiting structure includes a limiting member located on the movement path of the abutment portion along the lifting direction. The limiting member, located on the movement path of the abutment portion along the lifting direction, can directly mechanically limit the lifting movement of the unlocking component, clearly defining the maximum displacement of the unlocking component in the lifting direction. This design ensures that the unlocking component will not exceed the preset range due to excessive movement during the lifting process, avoiding interference or damage between the unlocking component and other components. Simultaneously, through the abutment of the limiting member and the abutment portion, in the lifting state, after the abutment portion on the unlocking component moves along the lifting direction to contact the limiting member, the limiting member blocks the abutment portion. At this time, the lifting force applied by the handle can be directly transmitted through the abutment portion of the unlocking component to the limiting member, and then from the limiting member to the housing, reducing the force transmission path and the stress burden on intermediate components.
[0025] Furthermore, the housing is provided with a limiting groove, and the abutment part is a slider slidably disposed within the limiting groove. The limiting element is the groove wall of the limiting groove along the lifting direction. The abutment part is designed as a slider slidably disposed within the limiting groove. The limiting groove forms multi-directional constraints on the movement of the slider, which not only limits the movement path of the unlocking element in the lifting direction, but also restricts its multi-directional offset, ensuring that the unlocking element and the locking tongue always cooperate accurately, reducing unlocking jamming caused by shaking, and improving the stability of unlocking and locking actions. By directly using the groove wall of the limiting groove as the limiting element, there is no need to set up an additional independent limiting component, making the internal structure of the housing more compact, saving space and reducing assembly complexity. This integrated design also reduces the mating gap between components and improves the reliability of the overall structure. When the slider slides to the groove wall (limiting component) in the limiting groove, the contact surface is larger and the force is more even. The lifting force of the handle is directly transmitted to the groove wall through the slider and then distributed to the housing. The force transmission path is more stable, which can effectively avoid component damage caused by excessive local stress. Especially in the lifting state, this combination can further enhance the smoothness of force transmission and structural durability.
[0026] Furthermore, at least one of the driven end and the unlocking part is provided with a guide structure for converting the lifting motion of the unlocking member into the unlocking displacement of the locking tongue. The guide structure can convert the lifting motion of the unlocking member driven by the handle into the unlocking displacement required by the locking tongue. This conversion does not require additional complex transmission components and can be completed through the cooperation of the structure itself, so that the unlocking action and the lifting action are naturally connected through the same operation, avoiding the operational separation caused by inconsistent movement directions in traditional designs.
[0027] Furthermore, the guide structure includes a guide ramp or a guide arc surface. The guide ramp or guide arc surface transmits force through a continuous and smooth contact interface, enabling a smoother conversion of the lifting motion of the unlocking element into the unlocking displacement of the latch. Compared to other forms of guide structures, the contact method of the ramp or arc surface reduces frictional resistance and stress concentration between the latch and the unlocking element, avoids jamming caused by abrupt changes in the contact surface, and makes the latch retraction process more continuous.
[0028] Furthermore, the housing is provided with a recessed groove for storing the handle, and the groove has a through hole for the connecting end to extend out of the housing. The recessed groove provides storage space for the handle, which can be flipped and stored in the groove when not in use, preventing the handle from being exposed and occupying extra space, making the overall battery structure more compact and reducing its volume in the device's battery compartment.
[0029] Furthermore, a second reset mechanism is provided between the unlocking component and the housing. This second reset mechanism exerts a force on the unlocking component in the opposite direction to the lifting direction. When the handle is not pulled by external force, the second reset mechanism can push the unlocking component back to its initial position through the reverse force, ensuring that the unlocking component does not interfere with the engagement between the latch and the battery compartment lock hole, thus guaranteeing the stability of the locked state. After the unlocking action is completed and the external lifting force disappears, the second reset mechanism can drive the unlocking component to reset, preparing for the next locking and unlocking action and preventing subsequent operations from being stuck or malfunctioning due to the unlocking component's positional displacement.
[0030] Furthermore, the unlocking component is provided with a through groove through which the locking end passes, with the unlocking part and the connecting end located at opposite ends of the through groove. The through groove provides a precise movement track for the locking end. During locking, the locking end passes through the through groove and engages with the locking part of the battery compartment. The through groove limits and guides the locking end, ensuring accurate insertion into the locking part and enhancing locking stability. During unlocking, the unlocking part pushes the bolt, and the through groove ensures a stable retraction path for the bolt, preventing it from shifting or jamming during unlocking, thus improving the reliability and smoothness of the unlocking action. This layout allows for a more compact and rational arrangement of components, achieving efficient distribution of functional components within the limited space of the housing, reducing space occupation, and also helping to simplify the overall structure, making the internal structure of the battery pack clearer and more orderly, facilitating manufacturing and subsequent maintenance.
[0031] A robot is also disclosed, comprising a battery placement cavity and a detachable battery pack as described in any of the above embodiments. The side wall of the battery placement cavity is provided with a locking part adapted to the locking end. This simple and efficient battery replacement design makes robot maintenance easier. On the one hand, operators can replace batteries without complex training or specialized tools, reducing labor costs; on the other hand, the stable and reliable battery installation structure reduces the probability of robot malfunctions due to battery installation problems, reducing maintenance costs and downtime losses, and improving the robot's economic efficiency. The locking tongue of the detachable battery pack precisely matches the locking part on the side wall of the battery placement cavity. During robot operation, even when subjected to external forces such as vibration and impact, the battery can be securely installed in the battery placement cavity, preventing the battery from loosening or shifting, ensuring the stability of the robot's overall structure, preventing battery shaking from affecting the robot's normal operation, and ensuring its operational accuracy and reliability.

Detailed Implementation
[0042] A detachable battery pack includes a housing 100 and battery cells 200 housed therein. The housing 100 is provided with a slidable latch 300, which has a locking end 310 for locking engagement and a driven end 320.
[0043] A first reset mechanism 400 is provided between the latch 300 and the housing 100, which is used to drive the latch 300 to reset to the initial locking position when the external force on the latch 300 disappears.
[0044] The housing 100 is also provided with an unlocking component 500, which includes an unlocking part 510 that abuts against the driven end 320 and a connecting end 520.
[0045] The connecting end 520 is rotatably connected to a handle 600, which has the following functions: unlocked state: driving the unlocking component 500 to push the driven end 320 to unlock the locking end 310; and lifting state: moving the unlocked battery pack.
[0046] The housing 100 is provided with a limiting structure 700, which is used to maintain the housing 100 and the unlocking member 500 in the lifting direction when the housing is in the lifting state.
[0047] The handle 600 and the unlocking component 500 are connected by rotation, allowing the handle 600 to drive the unlocking component 500 to push the driven end 320 of the latch 300 when the handle is unlocked, thus unlocking the locking end 310. When pulled, it directly moves the battery pack. Unlike traditional designs where the unlocking component 510 and the handle 600 are operated separately, this design combines the previously independent unlocking and pulling steps, simplifying the battery removal process and reducing the number of steps. Thanks to the cooperation between the latch 300 and the unlocking component 500, the unlocking and pulling actions are seamlessly connected during the operation of the handle 600. Users only need to operate the handle 600 to complete both unlocking and pulling sequentially, avoiding the interruption or jerking that can occur with separate steps in traditional designs, thus improving the user experience. The limiting structure 700 provided in the housing 100 can maintain the contact state between the housing 100 and the unlocking member 500 in the lifting direction when the housing is lifted, ensuring the stability of the force on the battery pack during the lifting process, avoiding the lifting effect due to structural loosening, and also ensuring the reliability of the overall structure.
[0048] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0050] 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 indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0052] See Figures 1 to 5 This invention provides an embodiment of a detachable battery assembly. The detachable battery assembly includes a housing 100 and a battery cell 200 housed therein. To facilitate the placement of the battery cell 200, the housing 100 may include a lower housing 100 and an upper housing 100, which, when combined, form an internal cavity for housing the battery cell 200 and other components. The housing 100 contains a slidable latch 300. In this embodiment, the latch 300 slides along the length of the housing 100. For ease of subsequent description, the length of the housing 100 is defined as the horizontal direction, and the height direction as the vertical direction. Therefore, in this embodiment, the latch 300 moves horizontally. The latch 300 includes a locking end 310 for locking engagement and a driven end 320. The locking end 310 generally extends out of the housing 100 and is used to engage with other components to lock the detachable battery assembly. The driven end 320 drives the locking end 310 to move horizontally. When the locking tongue 300 extends out of the housing 100, it is in a locked state; when the locking tongue 300 retracts, the locking end 310 is in an unlocked state.
[0053] A first reset mechanism 400 is provided between the latch 300 and the housing 100. The first reset mechanism 400 is mainly used to drive the latch 300 back to its initial locked position when the external force on the latch 300 disappears. That is, the latch 300 is generally in the locked position. Only when the battery assembly needs to be removed does it need to be unlocked. Unlocking requires applying external force to the latch 300. After the external force is removed, the first reset mechanism 400 can maintain the latch 300 in the locked state. The first reset mechanism 400 can be an elastic element such as a compression spring or a sheet spring. In this embodiment, for example... Figure 6 As shown, the first reset mechanism 400 is a compression spring, which abuts against the driven end 320. When the locking tongue 300 is retracted into the housing 100 by external force, the compression spring accumulates elastic potential energy. When the external force is removed, the elastic potential energy of the compression spring is released, pushing the locking tongue 300 to move in the direction of extending out of the housing 100, so that the locking tongue 300 returns to the locked position.
[0054] An unlocking component 500 is also provided within the housing 100. The unlocking component 500 includes an unlocking part 510 that abuts against the driven end 320 and a connecting part. The connecting part is rotatably connected to the handle 600. The user can hold the handle 600 and apply a pulling force to it, which will cause the unlocking component 500 to move vertically. The unlocking part 510 of the unlocking component 500 abuts against the driven end 320. The vertical movement of the unlocking component 500 will push the driven end 320 to move horizontally, thereby unlocking the latch 300. Therefore, the handle 600 has an unlocked state and a pulled state. In the unlocked state, the handle 600 drives the unlocking component 500 to push the driven end 320 to unlock the locking end 310. In the pulled state, the handle 600 moves the unlocked battery pack. For ease of explanation, in this embodiment, the handle 600 will move the battery pack vertically, that is, the pulling direction is vertical.
[0055] Since the handle 600 must be in the unlocked state before entering the lifting state, and the handle 600 and the unlocking component 500 need to have a certain displacement in the vertical direction when in the unlocked state, a limiting structure 700 is also provided inside the housing 100 to maintain the contact state between the housing 100 and the unlocking component 500 in the lifting direction when in the lifting state. The lifting force is transmitted to the unlocking component 500 through the handle and then to the housing 100, realizing the lifting of the entire battery pack.
[0056] The following will introduce the limiting structure 700, including but not limited to the specific forms of the limiting structure 700 listed below:
[0057] The first form: such as Figure 2 , Figure 6As shown, the limiting structure 700 includes a baffle plate fixedly connected to the housing 100. The baffle plate abuts against the latch 300 in the lifting direction, and the latch 300 abuts against the locking member in the lifting direction. That is, in the vertical direction, the baffle plate, latch 300, and unlocking member 500 are arranged in sequence from top to bottom. Specifically, the baffle plate is located above the latch 300, and the driven end 320 of the latch 300 abuts against the unlocking part 510 of the unlocking member 500. The baffle plate does not affect the horizontal movement of the latch 300, but only provides unidirectional limitation on the latch 300 in the vertical direction, preventing the latch 300 from moving in the lifting direction. The latch 300 also only limits the unlocking member 500 in the lifting direction. Thus, when the handle 600 is in the lifting state, a force transmission chain is formed: handle 600 → unlocking member 500 → latch 300 → baffle plate → housing 100. This structural design ensures that when the handle 600 is in the lifting state, the lifting force is stably transmitted to the blocking plate through the unlocking component 500 and the locking tongue 300, and then distributed to the housing 100 by the blocking plate. This ensures that the force on each component is balanced during the lifting process, preventing damage to a single component due to concentrated force and improving the structural reliability of the battery pack during lifting. The direct contact between the blocking plate and the locking tongue 300 strictly limits the excessive displacement of the locking tongue 300 in the lifting direction. Simultaneously, the contact between the locking tongue 300 and the unlocking component 500 indirectly limits the lifting stroke of the unlocking component 500, ensuring the stability of the position of each component in the lifting state and preventing the lifting effect from being affected by component loosening or displacement deviation. This design creates a tight linkage between the blocking plate, locking tongue 300, and unlocking component 500 in the lifting direction, reducing gaps and wobbling between components, further improving the compactness and coordination of the overall structure, and helping to maintain the continuity of unlocking and lifting actions.
[0058] The second form: can be implemented alone or in combination with the first form, such as... Figure 8 The diagram shows a structural schematic of the combined implementation of the first and second forms. Specifically, the unlocking component 500 is provided with an abutment portion 540, and the limiting mechanism includes a limiting member located on the movement path of the abutment portion 540 along the lifting direction. That is, in the lifting state, the unlocking component 500 directly contacts and abuts the housing 100 through the abutment portion 540 and the limiting member, forming a force transmission chain of handle 600 → unlocking component 500 → housing 100. Its structural form is more flexible, and the position of the limiting member and the structure of the abutment portion 540 can be set according to different housing 100 spaces and movement requirements. Without affecting the overall force transmission, it provides more possibilities for battery structural design, while ensuring the relative position of the unlocking component 500 and the housing 100 is stable in the lifting state.
[0059] The limiting member is located on the movement path of the abutment portion 540 along the lifting direction, and can directly form a mechanical limit on the lifting movement of the unlocking member 500, clearly limiting the maximum displacement of the unlocking member 500 in the lifting direction. This design ensures that the unlocking member 500 will not exceed the preset range due to excessive movement during the lifting process, and avoids interference or damage between the unlocking member 500 and other components.
[0060] After the abutment portion 540 on the unlocking member 500 moves along the lifting direction to contact the limiting member, the limiting member blocks the abutment portion 540. At this time, the lifting force applied by the handle 600 can be directly transmitted to the limiting member through the abutment portion 540 of the unlocking member 500, and then transmitted to the housing 100 by the limiting member. This process does not require the locking tongue 300 as an intermediate link, reducing the force transmission path and the stress burden on intermediate components, making the force transmission more direct and efficient. It also avoids the deformation or damage that the locking tongue 300 may experience due to excessive force during the lifting process, further improving the structural reliability and durability of the battery when lifting.
[0061] Furthermore, the housing 100 is provided with a limiting groove 130, and the abutment part 540 is a slider disposed within the limiting groove 130. The limiting element is the groove wall of the limiting groove 130 along the lifting direction. Through the cooperation between the limiting groove 130 and the slider, the limiting groove 130 can constrain the slider in multiple directions, not only limiting the movement path of the unlocking element 500 in the lifting direction, but also restricting its offset in multiple directions. This ensures that the inclined surface of the unlocking element 500 and the locking tongue 300 always fits precisely, reducing unlocking jamming caused by shaking and improving the stability of unlocking and locking actions. By directly using the groove wall of the limiting groove 130 as the limiting element, there is no need to set up an additional independent limiting component, making the internal structure of the housing 100 more compact, saving space and reducing assembly complexity. This integrated design also reduces the mating gap between components and improves the reliability of the overall structure. When the slider slides to the groove wall (limiting component) in the limiting groove, the contact surface is larger and the force is more even. The lifting force of the handle 600 is directly transmitted to the groove wall through the slider and then distributed to the housing 100. The force transmission path is more stable and can effectively avoid component damage caused by excessive local stress. Especially in the lifting state, this combination can further enhance the smoothness of force transmission and structural durability.
[0062] Based on the above embodiments, in this embodiment, at least one of the driven end 320 and the unlocking part 510 is provided with a guide structure 800. The guide structure 800 is used to convert the lifting movement of the unlocking member 500 into the unlocking displacement of the locking tongue 300. For example, in this embodiment, the handle 600 pulls the unlocking member 500 in a vertical direction, while the locking tongue 300 moves in a horizontal direction to unlock. Therefore, the guide structure 800 is needed to realize this conversion of power direction. This conversion does not require additional complex transmission components and can be completed through the cooperation of the structure itself, so that the unlocking action and the lifting action are naturally connected through the same operation, avoiding the operation separation caused by inconsistent movement directions in traditional designs, and further enhancing the integrated experience of "unlocking with a single lift".
[0063] Specifically, both the driven end 320 and the unlocking part 510 are provided with a guide structure 800. The guide structure 800 includes a guide slope or a guide arc surface. In this embodiment, a guide slope is used. The guide slopes of the driven end 320 and the unlocking part 510 have the same slope. Since the movement directions of the driven end 320 and the unlocking part 510 are perpendicular, the guide slopes with the same slope allow the unlocking part 510 and the driven end 320 to maintain planar contact when relative displacement occurs. In the lifting state, if a structure is adopted where the unlocking member 500 transmits force to the locking tongue 300 and then to the housing 100, the increased contact area between the unlocking part 510 and the driven end 320 can also make the locking tongue 300 more evenly stressed. The guide slope or guide arc surface transmits force through a continuous and smooth contact interface, which can more smoothly convert the movement of the unlocking member 500 in the lifting direction into the unlocking displacement of the locking tongue 300. Compared to other types of guide structures 800, the inclined or curved contact method reduces frictional resistance and stress concentration between the latch 300 and the unlocking element 500, avoiding jamming caused by abrupt changes in the contact surface. This makes the retraction process of the latch 300 more continuous. The inclination angle of the guide ramp and the curvature of the guide arc can be adjusted according to actual force requirements, flexibly adapting to different unlocking forces and displacement requirements. Due to the stable force transmission characteristics of the inclined and curved surfaces, the pushing force of the unlocking element 500 on the latch 300 will change evenly with the movement stroke during the user's lifting of the handle 600, avoiding sudden changes in force or a jerky feeling.
[0064] Based on the above embodiments, the housing 100 is provided with a recess 110 for storing the handle 600. When the handle 600 is not in use, it can be flipped and stored in the recess 110, avoiding the handle 600 from being exposed and occupying extra space, making the overall battery structure more compact and reducing the volume occupied in the battery compartment of the device. The recess 110 has a through hole for the connecting end 520 to extend out of the housing 100, providing a precise extension channel for the connecting end 520 of the handle 600 and the unlocking component 500. This ensures that the rotational connection between the handle 600 and the unlocking component 500 is not obstructed by the housing 100, and the structure of the through hole provides a certain guidance and limit for the movement of the connecting end 520, preventing the handle 600 from shifting or shaking during flipping or lifting, and ensuring reliable linkage between the handle 600 and the unlocking component 500.
[0065] A second reset mechanism 900 can also be provided between the unlocking component 500 and the housing 100. The second reset mechanism 900 exerts a force on the unlocking component 500 in the opposite direction to the lifting direction. That is, after the external force is removed, the second reset mechanism 900 can push the unlocking component 500 back to its initial position, ensuring that the unlocking component 500 will not interfere with the engagement between the latch 300 and the battery compartment lock hole, thus ensuring the stability of the locked state. After the unlocking action is completed and the lifting external force disappears, the second reset mechanism 900 can drive the unlocking component 500 to reset, preparing for the next locking and unlocking action. This avoids the unlocking component 500 from causing subsequent operations to stall or fail due to positional displacement, thus enhancing the smoothness of the "unlock-lift-reset" cycle. Through the continuous force of the second reset mechanism 900, the position of the unlocking component 500 in the non-operational state can be ensured, preventing the unlocking component 500 from accidentally moving due to external factors such as vibration or shaking, which could affect the locking effect of the latch 300. This further ensures the reliability of the connection between the battery and the battery compartment and prevents accidental unlocking. The second reset mechanism 900 can be a compression spring or a spring sheet. In this embodiment, a compression spring is used. When the handle 600 moves the unlocking member 500 in the lifting direction, it will compress the compression spring, causing the compression spring to accumulate elastic potential energy. When the user releases the handle 600, the elastic potential energy of the compression spring is released, pushing the unlocking member 500 back to the initial position.
[0066] Since the locking tongue 300 moves horizontally to lock and unlock, in order to better limit the movement direction of the locking tongue 300, in this embodiment, the unlocking member 500 is provided with a through groove 530 for the locking end 310 to pass through. The unlocking part 510 and the connecting end 520 are located at opposite ends of the through groove 530, that is, the connecting end 520 is on top and the unlocking part 510 is on the bottom. This layout makes the positions of the components more compact and reasonable, achieving efficient distribution of functional components within the limited space of the housing 100, reducing space occupation, and also helping to simplify the overall structure, making the internal structure of the battery pack clearer and more orderly, facilitating manufacturing and later maintenance. The through groove 530 provides a precise movement track for the locking end 310. During locking, the locking end 310 passes through the through groove 530 and engages with the locking part of the battery compartment. The through groove 530 limits and guides the locking end 310, ensuring accurate insertion into the locking part and enhancing locking stability. During unlocking, the unlocking part 510 pushes the bolt 300. The through groove 530 ensures a stable retraction path for the bolt 300, preventing it from shifting or jamming during unlocking, thus improving the reliability and smoothness of the unlocking action. The unlocking part 510 and the connecting end 520 are separated yet interconnected by the through groove 530. When the handle 600 rotates, driving the connecting end 520, the connecting end 520 can more stably transmit force to the unlocking part 510. The unlocking part 510, with the help of the through groove 530 structure, precisely applies force to the driven end 320 of the bolt 300, achieving the unlocking function. This structural design ensures closer and more reliable coordination between the handle 600, the unlocking component 500, and the locking tongue 300, improving the continuity of the entire battery pack unlocking and lifting operation.
[0067] This utility model also discloses a robot, including a battery placement cavity and a detachable battery pack according to any of the above-mentioned embodiments. The side wall of the battery placement cavity is provided with a locking part adapted to the locking end 310. For the robot, operators can replace the battery more quickly. The locking tongue 300 of the detachable battery pack is precisely adapted to the locking part on the side wall of the battery placement cavity. With the help of the limiting structure 700, the battery can be firmly installed in the battery placement cavity even when subjected to external forces such as vibration and impact during robot operation, preventing the battery from loosening or shifting, ensuring the stability of the overall robot structure, preventing the normal operation of the robot from being affected by battery shaking, and ensuring its operational accuracy and reliability. The simple and efficient battery replacement design makes robot maintenance easier. On the one hand, operators can replace the battery without complicated training and professional tools, reducing labor costs; on the other hand, the stable and reliable battery installation structure reduces the probability of robot failure due to battery installation problems, reduces maintenance costs and downtime losses, and improves the economic efficiency of robot use.
[0068] like Figure 6 , Figure 7As shown, in this embodiment, there is only one set of locking tongue 300 and only one set of corresponding unlocking component 500. When the battery needs to be removed, the handle 600 is pried out of the recess 110, and the handle 600 is rotated so that the handle 600 rotates 90 degrees relative to the unlocking component 500, that is, the handle 600 is turned to the vertical position. Then, the handle 600 is pulled upward. The handle 600 will have two strokes. The first stroke is to drive the unlocking component 500 to move upward, thereby pushing the locking tongue 300 to unlock, that is, the handle 600 will be in the unlocked state. The second stroke is to continue to pull the handle 600 based on the first stroke. The handle 600 will drive the battery pack to move upward and disengage from the battery placement cavity, that is, the handle 600 will be in the lifted state. Specifically, after the handle 600 is pulled out of the sink 110 and rotated to a vertical position, an upward pulling force is continued to be applied to the handle 600. The handle 600 drives the entire unlocking component 500 to move upward through the pivot. Since the unlocking part 510 of the unlocking component 500 and the driven end 320 of the locking tongue 300 abut against each other through the guide slope, the upward movement of the unlocking component 500 will push the locking tongue 300 into the housing 100. That is, the locking tongue 300 will disengage from the locking part of the battery placement cavity. As the handle 600 is pulled up further, the locking tongue 300 will eventually completely disengage from the locking part, realizing the locking of the locking tongue 300. At this point, if the handle 600 is pulled upwards, the locking tongue 300 will be abutted by the first reset mechanism 400, which will no longer be able to move or will be compressed. Alternatively, the locking tongue 300 may have moved all the way into the housing 100. The unlocking member 500 will exert an upward force on the locking tongue 300, forming a force transmission chain of "unlocking member 500 → locking tongue 300 → housing 100", thereby achieving the purpose of lifting the entire battery pack. In this embodiment, the locking tongue 300 and the plug 120 of the battery pack are located at opposite ends of the length of the battery pack, with the locking tongue 300 located at the front of the battery pack near the top and the plug 120 located at the rear of the battery pack near the bottom. Therefore, when the handle 600 lifts the battery pack, the head of the battery pack will be lifted first, and the battery pack will rotate first, allowing the plug 120 to disengage from the socket in the battery placement cavity, and then the entire battery pack will separate from the battery placement cavity. For heavier battery packs, two sets of identical locking tongues 300 can be set, along with two sets of corresponding unlocking components 500. The two handles 600 can be raised simultaneously to unlock both locking tongues 300 at the same time, making battery removal more stable.
[0069] The core of this invention lies in the fact that by rotating the handle 600 and the unlocking component 500, the traditionally separate "unlocking" and "lifting" operations are combined into a single, continuous action. Users only need to flip and pull the handle 600, and the unlocking is automatically completed through the cooperation of the unlocking component 500 and the locking tongue 300 (e.g., guided by a beveled / arc surface), eliminating the need for additional operation of the unlocking part 510. This significantly reduces operational complexity and solves the problems of cumbersome steps and poor coordination in traditional designs.
[0070] Locked state: The first reset mechanism 400 (lock tongue 300 spring) continuously applies elastic force to make the lock tongue 300 stably inserted into the battery compartment lock hole. In conjunction with the second reset mechanism 900 (unlocking part 500 spring) to limit the unlocking part 500, it ensures that the engagement between the lock tongue 300 and the lock hole is not disturbed in the non-operation state, and prevents the battery from accidentally falling out.
[0071] Unlocking process: The guide structure 800 (sloping / arc surface) smoothly converts the lifting motion of the handle 600 into the retraction displacement of the bolt 300, reducing the risk of jamming; through the cooperation of the slider and the limiting groove, the guiding of the bolt 300 by the through groove 530, and the guiding of the unlocking component 500 by the through hole, the movement trajectory of the bolt 300 and the unlocking component 500 is further constrained to ensure that the unlocking action is accurate and in place.
[0072] Lifting state: The limiting structure 700 (blocking plate, limiting groove wall, etc.) ensures that the lifting force is stably transmitted to the housing 100 through the force transmission path of "unlocking component 500-locking tongue 300-limiting structure 700-housing shell 100" or "unlocking component 500-limiting structure 700-housing shell 100", avoiding excessive local force that could damage the components.
[0073] The present invention is applicable to various devices that require removable batteries (such as robots, portable energy storage devices, etc.). Through modular structural design, the component parameters (such as inclined plane angle, spring force, and limit structure 70° form) can be flexibly adjusted according to the space, load-bearing and operation requirements of different devices, and it has strong adaptability and expandability.

Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
