Description

Technical Field

[0001] This utility model relates to the field of battery technology, specifically to a handle assembly and a battery pack. Background Technology

[0002] With the increasing popularity of electrical devices (such as power tools, cleaning appliances, battery-powered cars, and electric bicycles), rechargeable battery packs have become widely used. For ease of carrying and replacement, these battery packs are typically equipped with handles and require a locking mechanism to secure them to a slot on the electrical device.

[0003] In related technologies, the handle function of a battery pack and the locking / unlocking function of the latch are often independent of each other. Specifically, the handle only serves the function of lifting and carrying the battery; while the extension and retraction of the latch is usually controlled by a separate button or lever. This design forces users to use both hands when removing the battery pack: one hand presses the unlock button to retract the latch, and the other hand can then lift the battery pack to remove it from the main unit. This process is cumbersome and time-consuming, and it is even more inconvenient to detach the battery pack from the device in situations where space is limited or the user has difficulty using one hand. Utility Model Content

[0004] The present invention provides a handle assembly that integrates lifting the battery body and unlocking the battery body into one action, eliminating the need for the user to find and operate a separate unlocking mechanism, thus simplifying and automating the operation process.

[0005] In a first aspect, embodiments of this application provide a handle assembly, including a handle, a latch, and a linkage belt; the handle is mounted on the battery body for lifting the battery body; the handle is movable relative to the battery body; the latch is mounted on the battery body; the latch is movable relative to the battery body to extend and retract from the battery body; one end of the linkage belt is connected to the handle, and the other end is connected to the latch; when the handle lifts the battery body, causing the handle to move relative to the battery body, the handle can drive the latch to move with the linkage belt, so that the latch retracts into the battery body.

[0006] The above-mentioned technical features have at least the following advantages and beneficial effects: The handle can be used not only to lift the battery body for easy transport and movement, but also to move the latch along a linkage belt as it moves relative to the battery body. This causes the latch to retract into the battery body, integrating the lifting and unlocking of the battery body into a single action. This eliminates the need for users to find and operate a separate unlocking mechanism, simplifying and automating the operation.

[0007] In one embodiment, the system further includes a fixing bracket fixed within the battery body; the latch is slidably connected to the fixing bracket so that one end of the latch can extend and retract into the battery body. The fixing bracket supports the latch, allowing it to slide within the battery body.

[0008] In one embodiment, a guide is formed on the fixed bracket, and the linkage belt is wound around the guide. The end of the linkage belt near the latch is a first segment. One end of the first segment is connected to the latch, and the other end is attached to the guide. The angle between the extension direction of the first segment and the sliding direction of the latch is an acute angle. The acute angle between the extension direction of the first segment of the linkage belt and the sliding direction of the latch ensures that the force of the linkage belt can be used more to pull the latch to slide, thus ensuring the reliability of the latch sliding.

[0009] In one embodiment, one end of the guide member is a guide end; the projection of the guide end in the sliding direction of the latch is at least partially located on the latch; the end of the first segment facing away from the latch is attached to the guide end. The guide end guides the linkage belt, ensuring its direction of rotation and enabling it to pull the latch to slide.

[0010] In one embodiment, the linkage further includes a second segment; one end of the second segment is connected to the handle; the other end is connected to the end of the first segment facing away from the latch; the second segment and the first segment have an included angle. The end of the second segment facing the first segment is attached to the guide end, and the first segment is connected to the latch, ensuring that the force of the second segment can be applied to the first segment to drive the latch to slide.

[0011] In one embodiment, the fixed bracket has a sliding groove that extends along the sliding direction of the latch; the latch is slidably disposed within the sliding groove. The sliding groove is used to limit and guide the sliding of the latch.

[0012] In one embodiment, the latch has a through-hole extending along the sliding direction of the latch; a protruding limiting post is formed within the sliding groove, passing through the through-hole; when the latch extends and retracts, the limiting post abuts against the sidewall of the through-hole to limit the sliding stroke of the latch. During latch sliding, at the extended and retracted positions, both ends of the through-hole contact the limiting post, thereby preventing further movement of the latch. This limits the extension and retraction positions of the latch, preventing excessive extension or retraction.

[0013] In some embodiments, a detachable fixing plate is fixed to the fixing bracket; the fixing plate is fixed to the open side of the sliding groove and abuts against the locking tongue; a limiting hole is formed on the fixing plate; the free end of the limiting post passes through the limiting hole, and the free end of the limiting post contacts the side wall of the limiting hole. The contact of the limiting post within the limiting hole enhances the bending stiffness and strength of the limiting post, making it less prone to deformation or breakage when subjected to the impact force of the locking tongue, thus ensuring the long-term effectiveness of the travel limiting function.

[0014] In one embodiment, a recessed receiving cavity is formed on the sidewall of the sliding groove; an elastic element is disposed within the receiving cavity; one end of the elastic element abuts against the latch, and the other end abuts against the sidewall of the receiving cavity, thereby driving the latch to extend out of the battery body. The elastic element is used to maintain the latch in the extended state, ensuring locking on the electrical equipment.

[0015] In one embodiment, the latch has a protruding portion that extends into the receiving cavity; the protruding portion has a protruding post that extends parallel to the sliding direction of the latch; the elastic element is a spring; the elastic element is sleeved on the outer periphery of the protruding post; the opposite ends of the elastic element abut against the protruding portion and the sidewall of the receiving cavity, respectively. This allows the elastic element to be confined between the latch and the fixed bracket.

[0016] In one embodiment, a buffer section is provided at the end of the linkage belt facing the handle; a first buffer spring is provided between the buffer section and the handle for buffering when the handle pulls the latch.

[0017] In one embodiment, the handle has a first mounting cavity; the first mounting cavity has a first stop; the linkage belt extends into the first mounting cavity, and a first moving member is provided at one end of the linkage belt extending into the first mounting cavity; the two opposite ends of the first buffer spring abut against the first stop and the first moving member respectively to achieve buffering.

[0018] In one embodiment, the handle is further provided with a pull strap, one end of which is connected to the handle and the other end is fixed to the battery body; the pull strap and the linkage belt are arranged at intervals at both ends of the handle. The arrangement of the pull strap and the linkage belt is to parallel the forces acting on the handle at opposite ends, thus maintaining the stability of the handle's force.

[0019] In one embodiment, a second buffer spring is provided between the pull strap and the handle to buffer the force exerted by the handle on the battery body.

[0020] In one embodiment, the handle is provided with a second mounting cavity; the second mounting cavity is provided with a second stop; the pull strap extends into the second mounting cavity, and a second movable member is provided at one end of the pull strap extending into the second mounting cavity; the two opposite ends of the second buffer spring abut against the second stop and the second movable member respectively; the side of the second movable member facing away from the second stop can abut against the side wall of the second mounting cavity to achieve buffering.

[0021] Secondly, embodiments of this application provide a battery pack, including a battery body and the aforementioned handle assembly. Attached Figure Description

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of the present utility model and are not intended to limit the present utility model. In the present utility model, unless otherwise stated, directional terms such as "upper" and "lower" generally refer to the upper and lower positions of the device in actual use or operation, specifically the drawing directions in the accompanying drawings; while "inner" and "outer" refer to the outline of the device.

[0039] The handle function of a battery pack and the locking / unlocking function of the latch are often independent. Specifically, the handle only serves the function of lifting and carrying the battery; while the extension and retraction of the latch is usually controlled by a separate button or lever. This design means that users must use both hands to remove the battery pack: one hand presses the unlock button to retract the latch, and the other hand can then lift the battery pack to remove it from the main unit. This process is cumbersome and time-consuming, and it is even more inconvenient to detach the battery pack from the device in situations where space is limited or the user has difficulty using one hand.

[0040] One objective of this application is to design a structure that facilitates easy separation, enabling the battery pack to be unlocked and lifted with a single action, thus simplifying battery pack disassembly. The following description is in conjunction with the accompanying drawings.

[0041] Figure 1 This is a schematic diagram of the battery pack structure shown in an embodiment of this application. Figure 2 This is a partial structural schematic diagram of the battery pack shown in an embodiment of this application.

[0042] See Figure 1 and Figure 2 This application embodiment illustrates a battery pack for storing and releasing electrical energy to power electrical devices such as power tools, cleaning appliances, battery-powered cars, and electric bicycles.

[0043] The battery pack is detachably mounted on the electrical equipment for easy removal and replacement. The equipment has a slot, and the battery pack has a corresponding locking mechanism. The locking mechanism detachably engages with the slot, allowing the battery pack to be locked to the equipment and unlocked relative to it.

[0044] The battery pack includes a battery body 10 and a handle assembly 20. The battery body 10, as the main structure of the battery pack, is used to store and release electrical energy. The handle assembly 20 is provided on the battery body 10 for lifting the battery pack, thereby facilitating its movement.

[0045] For ease of description and understanding, the direction in which the handle assembly 20 pulls the battery pack is considered the upward direction.

[0046] See again Figure 1 and Figure 2 The battery body 10 includes a lower shell 11, an upper cover 12 covering the lower shell 11, and a battery main body (not shown in the figure). The battery main body is the main structure used for storing and releasing electrical energy. The lower shell 11 and the upper cover 12 enclose a space for accommodating the battery main body.

[0047] In one embodiment, the handle assembly 20 is fixed to the top cover 12. The handle assembly 20 pulls the battery body 10 upward, thereby unlocking the battery body 10 and the electrical device, and moving the battery body 10 upward. The unlocking and movement of the battery body 10 are achieved through a single lifting action.

[0048] Figure 3 This is a cross-sectional view of the battery pack structure of this application. Figure 4 This is a schematic diagram of the structure of an embodiment of the handle component 20 of this application.

[0049] See Figures 2 to 4 The handle assembly 20 includes a handle 100, a latch 220, and a linkage belt 300. The handle 100 is mounted on the outside of the battery body 10 and is used to lift the battery body 10. The handle 100 and the latch 220 are connected by the linkage belt 300. When the handle 100 lifts the battery body 10, the handle 100 can drive the latch 220 to move with the linkage belt 300.

[0050] In one embodiment, the handle 100 is positioned above the battery body 10 to allow the battery body 10 to be pulled upwards, thereby moving the battery body 10. For example, the handle 100 is positioned above and attached to the top cover 12.

[0051] In some embodiments, a latch 220 is mounted on the battery body 10; the latch 220 is movable relative to the battery body 10 to extend and retract. When the battery pack is installed in an electrical device, the latch 220 extends from the battery body 10, thereby engaging with a corresponding slot in the electrical device. The latch 220 retracts from the battery body 10, thereby unlocking the battery pack and the electrical device, allowing the battery pack to be detached from the electrical device.

[0052] In some examples, the latch 220 is located within the cover 12 and is slidable within the cover 12 to extend and retract within the cover 12.

[0053] In some embodiments, one end of the linkage belt 300 is connected to the handle 100, and the other end is connected to the latch 220. The handle 100 is movable relative to the battery body 10. The movement of the handle 100 relative to the battery body 10 causes the latch 220 to slide.

[0054] In some examples, the latch 220 is horizontally slidable on the battery body 10. A handle 100 is positioned above the battery body 10, and the handle 100 can lift the battery body 10 upwards. The upward movement of the handle 100 relative to the battery body 10 moves the linkage belt 300, which in turn moves the latch 220 horizontally.

[0055] In one example, the latch 220 is slidably mounted vertically on the battery body 10, and the handle 100 moves horizontally or vertically relative to the battery body 10, causing the latch 220 to slide vertically.

[0056] The handle 100 can not only be used to lift the battery body 10 for easy handling and movement, but also, when the handle 100 is moving relative to the battery body 10, it drives the locking tongue 220 to move with the linkage belt 300, so that the locking tongue 220 retracts into the battery body 10. This integrates lifting the battery body 10 and unlocking the battery body 10 into a single action, eliminating the need for the user to find and operate a separate unlocking mechanism, thus simplifying and automating the operation process.

[0057] Figure 5 This is a cross-sectional view of the 12 embodiments of the present application.

[0058] See Figures 3 to 5 The upper cover 12 has a through hole 13 for the linkage belt 300 to pass through. One end of the linkage belt 300 extends out of the upper cover 12 and is connected to the handle 100. The other end of the linkage belt 300, facing away from the handle 100, extends into the upper cover 12 and is connected to the locking tongue 220.

[0059] The upper cover 12 has a lock hole 14. When the lock tongue 220 slides, the lock tongue 220 can pass through the lock hole 14, so that the lock tongue 220 can extend and retract into the upper cover 12.

[0060] In some embodiments, the upper surface of the cover 12 is formed with a recessed handle groove 15, and the handle 100 is located at least at its lower end within the handle groove 15. A through hole 13 is formed within the handle groove 15, and the linkage belt 300 passes through the through hole 13 and is connected to the handle 100.

[0061] In other embodiments, a downwardly protruding fixing post 16 is formed on the upper wall inside the upper cover 12. The fixing post 16 is used to fix to the corresponding structure of the handle 100 structure so that the locking tongue 220 is limited inside the upper cover 12.

[0062] Figure 6 This is a schematic diagram of the structure of an embodiment of the handle 100 of this application. Figure 7 This is a partial structural schematic diagram of an embodiment of the handle 100 of this application. Figure 8 This is a structural schematic diagram of an embodiment of the linkage belt 300 of this application.

[0063] See Figures 6 to 8 One end of the handle 100 is fixed to the battery body 10, and the other end of the handle 100 is connected to the linkage belt 300. The movement of the handle 100 relative to the battery body 10 causes the locking tongue 220 to slide.

[0064] In one embodiment, a buffer section 310 is provided at the end of the linkage belt 300 facing the handle 100; a first buffer spring 140 is provided between the buffer section 310 and the handle 100. At the moment of lifting, the linkage belt 300 suddenly tightens, generating an impact force. The first buffer spring 140 effectively absorbs this impact force, thereby protecting the entire transmission mechanism and extending its service life. The first buffer spring 140 provides a smooth transition during the initial lifting phase, resulting in a better user experience.

[0065] In one example, a first mounting cavity 110 is provided inside the handle 100; a first stop portion 111 is provided inside the first mounting cavity 110; a linkage belt 300 extends into the first mounting cavity 110, and a first moving member 311 is provided at one end of the linkage belt 300 extending into the first mounting cavity 110; the two opposite ends of the first buffer spring 140 abut against the first stop portion 111 and the first moving member 311, respectively.

[0066] For example, the first buffer spring 140 is a buffer spring, with its two ends abutting against the first stop 111 and the first moving member 311, respectively. When the handle 100 is pulled, the first moving member 311 moves toward the first stop 111 to provide a buffering force, so that the pulling force of the handle 100 is slowly transmitted to the latch 220 through the linkage belt 300, thereby making the pulling force on the latch 220 more stable.

[0067] In one embodiment, the side of the first movable member 311 facing away from the first stop 111 can abut against the side wall of the first mounting cavity 110. When the handle 100 is not pulled, the handle 100 is in its initial state. In the initial state, the side of the first movable member 311 facing away from the first stop 111 can abut against the side wall of the first mounting cavity 110, keeping the linkage 300 and the handle 100 relatively stationary, so that the linkage 300 does not exert force on the locking tongue 220.

[0068] In one embodiment, a pull strap 130 is also provided on the handle 100, with one end of the pull strap 130 connected to the handle 100 and the other end fixed to the battery body 10; the pull strap 130 and the linkage belt 300 are arranged at intervals at both ends of the handle 100. The handle 100 and the linkage belt 300 form symmetrical or balanced force points, so that the force is evenly distributed when lifting, the battery pack remains horizontal and stable, and the smoothness and comfort of the lifting process are improved.

[0069] In one example, a second buffer spring 150 is provided between the pull strap 130 and the handle 100. A first buffer spring 140 is provided between the handle 100 and the linkage belt 300, and a second buffer spring 150 is provided between the pull strap 130 and the handle 100, so that both sides of the handle 100 have a gentle buffering effect in the initial stage of lifting, making the operation feel more consistent and comfortable.

[0070] In some embodiments, a second mounting cavity 120 is provided in the handle 100; a second stop portion 121 is provided in the second mounting cavity 120; a pull strap 130 extends into the second mounting cavity 120, and a second moving member 131 is provided at one end of the pull strap 130 extending into the second mounting cavity 120; the two opposite ends of the second buffer spring 150 abut against the second stop portion 121 and the second moving member 131, respectively.

[0071] For example, the second buffer spring 150 is a buffer spring, and the two ends of the second buffer spring 150 abut against the second stop 121 and the second moving member 131 respectively. When the handle 100 is pulled up, the second moving member 131 moves toward the second stop 121 to provide a buffering force, thereby making the pulling force of the handle 100 on the battery body more gentle.

[0072] The pull belt 130 and the linkage belt 300 are respectively equipped with buffer springs to maintain the balance of the forces acting on the handle 100 at both ends.

[0073] In some embodiments, the side of the second movable member 131 facing away from the second stop 121 can abut against the side wall of the second mounting cavity 120. When the handle 100 is not pulled, the handle 100 is in its initial state. In the initial state, the side of the second movable member 131 facing away from the second stop 121 can abut against the side wall of the second mounting cavity 120, maintaining the relative stillness between the pull strap and the handle 100, and maintaining the initial position of the handle 100.

[0074] Figure 9 This is a schematic diagram of the locking structure 200 of this application. Figure 10 This is a cross-sectional view of the locking structure 200 of this application. Figure 11 This is a structural schematic diagram of the fixed bracket 210 of this application.

[0075] See Figures 9 to 11 The handle assembly 20 includes a locking structure 200, which includes a fixed bracket 210 and a latch 220 slidably disposed on the fixed bracket 210. The fixed bracket 210 is fixed inside the battery body 10, and the latch 220 is slidably connected to the fixed bracket 210 so that one end of the latch 220 can extend and retract into the battery body 10.

[0076] In one embodiment, the fixing bracket 210 has a fixing hole 211, which is connected to the fixing post 16 on the top cover 12, so that the fixing bracket 210 is fixed inside the battery body 10.

[0077] In another embodiment, the fixing bracket 210 is part of the battery body 10 and is formed on the upper cover 12 or lower shell 11 of the battery body 10.

[0078] In one embodiment, the fixed bracket 210 has a sliding groove 212 extending along the sliding direction of the latch 220; the latch 220 is slidably disposed within the sliding groove 212. The sliding groove 212 defines the sliding direction of the latch 220. For example, the latch 220 slides horizontally, the sliding groove 212 is horizontally disposed, and the extending direction of the sliding groove 212 is parallel to the sliding direction of the latch 220.

[0079] In some embodiments, one side of the sliding groove 212 is open, allowing the latch 220 to be installed into the sliding groove 212 from the open side, facilitating the installation and maintenance of the latch 220 on the fixed bracket 210. For example, the upper end of the sliding groove 212 is open, allowing the latch 220 to be inserted into the sliding groove 212 from top to bottom.

[0080] See again Figures 9 to 11 A guide 213 is formed on the fixed bracket 210, and a linkage belt 300 is wound around the guide 213. The end of the linkage belt 300 near the latch 220 is a first segment 320; one end of the first segment 320 is connected to the latch 220, and the other end is attached to the guide 213. By guiding the linkage belt 300 through the guide 213, the direction of extension of the linkage belt 300 is changed, thereby converting the force of the handle 100's movement into a force for pulling the latch 220 to slide. For example, when the handle 100 moves upward relative to the battery body 10, it pulls the linkage belt 300. Under the action of the guide 213, one segment of the linkage belt 300 moves horizontally.

[0081] In one example, the angle between the extension direction of the first segment 320 and the sliding direction of the latch 220 is an acute angle, ensuring that the linkage belt 300 has a greater force in the sliding direction of the latch 220, thereby more stably pulling the latch 220 back into the battery body 10.

[0082] In a specific example, the extension direction of the first segment 320 is parallel to the sliding direction of the locking tongue 220.

[0083] In one embodiment, one end of the guide member 213 is a guide end 214; the projection of the guide end 214 in the sliding direction of the latch 220 is at least partially located on the latch 220; the end of the first segment 320 facing away from the latch 220 is attached to the guide end 214, thereby ensuring that the tension of the linkage belt 300 acts directly on the latch 220. For example, the guide end 214 is located at the lower end of the guide member 213.

[0084] In one example, the latch 220 is slidably disposed in the sliding groove 212, and the guide end 214 is located in the sliding groove 212, so that the projection of the sliding direction of the first segment 320 of the linkage belt 300 and the latch 220 coincides, ensuring that the tension of the linkage belt 300 is fully used to drive the latch 220 to slide.

[0085] In one embodiment, the guide member 213 is also provided with a guide hole 215, through which the linkage belt 300 passes. The guide hole 215 corresponds to the through hole 13 on the upper cover 12.

[0086] In one example, via 13 is located above guide hole 215, and guide end 214 is located below guide hole 215. Linkage belt 300 extends downward after passing through via 13 and guide hole 215, and turns at guide end 214.

[0087] In one embodiment, the linkage belt 300 further includes a second segment 330; one end of the second segment 330 is connected to the handle 100; the other end is connected to the end of the first segment 320 facing away from the latch 220; the second segment 330 and the first segment 320 have an included angle. Through the guiding effect of the guide end 214, the movement direction of the linkage belt 300 is turned into a movement direction that can drive the latch 220 to move.

[0088] In another embodiment, the linkage belt 300 includes a first segment 320, a second segment 330, and a buffer segment 310; the second segment 330 is connected to the buffer segment 310, and the buffer segment 310 is connected to the handle 100.

[0089] Figure 12 This is a structural schematic diagram from one perspective of an embodiment of the locking tongue 220 of this application. Figure 13 This is a structural schematic diagram from another perspective of the embodiment of the locking tongue 220 of this application.

[0090] See Figures 9 to 13 The latch 220 is limited within the sliding groove 212 of the fixed bracket 210, and the latch 220 can slide along the extending direction of the sliding groove 212. The latch 220 is provided corresponding to the lock hole 14 on the battery body 10, and the latch 220 can slide within the lock hole 14 to ensure that the latch 220 can extend and retract into the battery body 10.

[0091] The locking tongue 220 is provided with a connecting part 221, which is used to connect with the linkage belt 300. The connecting part 221 has a mating hole 225, and a fastener is provided between the linkage belt 300 and the mating hole 225. The fastener is a bolt, screw or rivet, etc.

[0092] In some embodiments, a recessed receiving cavity 216 is formed on the sidewall of the sliding groove 212; an elastic member 230 is disposed in the receiving cavity 216; one end of the elastic member 230 abuts against the locking tongue 220, and the other end abuts against the sidewall of the receiving cavity 216, so as to drive the locking tongue 220 to extend out of the battery body 10, maintain the state of the locking tongue 220 extending out of the battery body 10, and maintain the battery pack locked on the electrical device. For example, the elastic member 230 is a compression spring.

[0093] In one example, the latch 220 has a protruding portion 222 extending into the receiving cavity 216; the protruding portion 222 has a protruding post 223 extending in a direction parallel to the sliding direction of the latch 220; the elastic element 230 is a spring; the elastic element 230 is sleeved on the outer periphery of the post 223; the opposite ends of the elastic element 230 abut against the protruding portion 222 and the sidewall of the receiving cavity 216, respectively. For example, the latch 220 is horizontally slidably mounted on the fixed bracket 210, and the protruding portion 222 protrudes from the lower surface of the latch 220.

[0094] In one embodiment, the latch 220 has a through-hole 224 extending along the sliding direction of the latch 220; a protruding limiting post 217 is formed in the sliding groove 212, and the limiting post 217 passes through the through-hole 224. When the latch 220 extends and retracts, the limiting post 217 can abut against the side wall of the through-hole 224 to limit the sliding stroke of the latch 220.

[0095] When the latch 220 slides, both ends of the elongated hole 224 contact the limiting post 217 in the extended and retracted positions, thereby preventing the latch 220 from moving further. This limits the extension and retraction of the latch 220, preventing it from over-extending or over-retracting. The limiting post 217, passing through the elongated hole 224, also provides auxiliary guidance for the movement of the latch 220, while maintaining a compact structure and not occupying additional space.

[0096] Figure 14 This is a structural schematic diagram of an embodiment of the fixing plate 240 of this application.

[0097] See Figure 9 , Figure 10 and Figure 14 A detachable fixing plate 240 is fixed to the fixing bracket 210; the fixing plate 240 is fixed to the open side of the sliding groove 212 and abuts against the locking tongue 220. The fixing plate 240 can limit the locking tongue 220 on the sliding groove 212, preventing the locking tongue 220 from jumping out from the open side of the sliding groove 212. For example, the fixing plate 240 is fixed to the upper surface of the fixing bracket 210.

[0098] In one embodiment, a fixing part 241 is provided on the fixing plate 240, and a through hole 242 is provided on the fixing part 241. The through hole 242 communicates with the fixing hole 211 of the fixing bracket 210. Both the through hole 242 and the fixing hole 211 are fixed to the fixing post 16 of the upper cover 12 by fasteners.

[0099] In some embodiments, the fixed bracket 210 is further provided with a connecting post 218, and the fixed plate 240 is provided with a corresponding connecting hole 243. The connecting hole 243 and the connecting post 218 are connected by fasteners to fix the fixed plate 240 on the fixed bracket 210.

[0100] In other embodiments, a protruding limiting post 217 is provided within the sliding groove 212, and a limiting hole 244 is provided on the fixing plate 240. The free end of the limiting post 217 passes through the limiting hole 244, and the free end of the limiting post 217 contacts the side wall of the limiting hole 244. The contact of the limiting post 217 within the limiting hole 244 enhances the bending stiffness and strength of the limiting post 217, making it less prone to deformation or breakage when subjected to the impact force of the locking tongue 220, thus ensuring the long-term effectiveness of the stroke limiting function. At the same time, the limiting hole 244 on the fixing plate 240 and the limiting post 217 on the sliding groove 212 form a positioning relationship, which helps to ensure the accuracy of its position when assembling the fixing plate 240.

[0101] Based on the above structure, when the handle 100 is pulled, the handle 100 moves relative to the battery body 10. The force of the handle 100 is transmitted to the locking tongue 220 through the linkage belt 300, causing the locking tongue 220 to retract into the battery body 10. The battery pack and the corresponding electrical equipment are unlocked. If the handle 100 is pulled further, the battery pack moves, and the battery pack and the corresponding electrical equipment are separated.

[0102] The lifting force of the handle 100 is converted into a force that retracts the locking tongue 220 through the transmission of the linkage belt 300. The movement of the battery pack and the unlocking of the battery pack are integrated into one action, which facilitates the separation of the battery pack from the electrical equipment.

The description of the above embodiments is only for the purpose of helping to understand the method and core ideas of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the ideas of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
