Description

Technical Field

[0001] This application relates to the field of batteries, and in particular to a battery pack and an electrical device. Background Technology

[0002] Rechargeable battery cells are those that can be recharged after being discharged, allowing the active materials to be reactivated and reused. Rechargeable battery cells are widely used in electronic devices such as mobile phones, laptops, and drones.

[0003] Battery packs typically consist of multiple cells to meet the voltage requirements of electronic devices. Improving the reliability of battery packs has been a key research focus in the development of battery technology. Summary of the Invention

[0004] This application provides a battery pack and electrical device that improves reliability and assembly / disassembly efficiency.

[0005] In a first aspect, this application provides a battery pack including a battery body and a handle. The battery body includes a first connector. The handle is rotatably connected to the battery body. The handle is configured to switch between a first state and a mating part of an electrical device by rotation; in the first state, the first connector and a second connector of the electrical device are connected; in the second state, the battery body and the mating part are disconnected.

[0006] The addition of a handle facilitates lifting and transporting the battery pack. The handle secures the battery body to its mating components, reducing the risk of separation between the first and second connectors when the equipment is subjected to external impacts, thus improving safety and reliability. During battery pack installation, the handle can be rotated to secure the battery body to the mating components; when removing the battery pack, rotating the handle releases the connection. Rotating the handle also allows switching between a first and second state, simplifying the installation and removal of the battery pack and improving efficiency. This embodiment further integrates the handle's rotation with the connection between the first and second connectors, further enhancing the efficiency of battery pack installation and removal.

[0007] In some embodiments, the handle is detachably connected to the battery body. The handle can be quickly replaced when needed, reducing battery pack maintenance costs.

[0008] In some embodiments, the handle includes two rotating arms, a connecting rod, and at least one engaging member. The two rotating arms are respectively disposed on both sides of the battery body and rotatably connected to the battery body along a first direction, which is parallel to the rotation axis of the handle. The connecting rod connects the two rotating arms. The engaging member is disposed on the rotating arms and is used to engage with a mating component in a first state.

[0009] By setting two rotating arms, the stability of the connection between the handle and the battery body can be improved, reducing the risk of the connection between the handle and the battery body failing when transporting the battery pack.

[0010] In some embodiments, the handle includes two engaging members, which are respectively connected to two rotating arms.

[0011] By setting two locking components, the locking strength between the handle and the mating parts can be increased, improving the stability of the battery pack. This also reduces the risk of the first connector separating from the second connector when the electrical equipment is subjected to external impact, thus improving safety and reliability.

[0012] In some embodiments, the engaging member is detachably connected to the swing arm.

[0013] In some embodiments, the engaging member is detachably connected to the swing arm by fasteners.

[0014] In some embodiments, the rotating arm is connected to the battery body via a rotating shaft.

[0015] In some embodiments, when viewed along the first direction, the distance between the connecting rod and the rotation axis is greater than the distance between the engaging member and the rotation axis.

[0016] During the process of engaging or disengaging the engaging component with the mating component, the engaging component will experience resistance. According to torque balance, the greater the distance between the connecting rod and the rotation axis, the less force the user needs to apply when rotating the handle; the embodiments of this application reduce the force required for the user to rotate the handle, making it easier for the user to switch between the first state and the second state.

[0017] In some embodiments, the engaging member has a slot for engaging with a mating member. In the first state, the mating member can be inserted into the slot to engage with the engaging member.

[0018] In some embodiments, the engaging member includes an engaging body, a first engaging arm, and a second engaging arm, the first engaging arm and the second engaging arm protruding from the same side of the engaging body. The first engaging arm is located on the side of the second engaging arm closer to the rotation axis, and a groove is formed between the first engaging arm and the second engaging arm.

[0019] When the mating component is inserted into the slot, the first and second locking arms can limit the mating component from both sides.

[0020] In some embodiments, the swivel arm has a recess in which at least a portion of the engaging body and at least a portion of the first engaging arm are received.

[0021] The recessed area serves a positioning function during the assembly of the rotating arm and locking components, simplifying the assembly process. By incorporating the recess, the weight of the handle can be reduced, thus minimizing the overall space occupied by the handle. Furthermore, the recessed area reduces the distance between the locking components and the rotation axis, lowering the resistance torque when rotating the handle.

[0022] In some embodiments, the second engaging arm extends in a dimension greater than the first engaging arm in a direction away from the engaging body.

[0023] When the handle is rotated, the portion of the second engaging arm that extends beyond the first engaging arm can guide the mating components into the slot.

[0024] In some embodiments, the first direction, the second direction, and the third direction are perpendicular to each other. The dimension of the battery body along the first direction is larger than the dimension of the battery body along the third direction, and the dimension of the battery body along the second direction is larger than the dimension of the battery body along the third direction. A rotating arm is rotatably connected to the end of the battery body along the second direction.

[0025] The connecting rod needs to rotate around the rotation axis on the outside of the battery body, and the swing arm needs to have a certain size to avoid interference between the connecting rod and the battery body during rotation. The battery body has a smaller dimension along the third direction. By rotatably connecting the swing arm to the end of the battery body along the second direction, the size requirements for the swing arm can be reduced, thus reducing the weight of the handle.

[0026] In some embodiments, the handle is configured such that: when the connecting rod and the rotation axis are arranged along a second direction, the engaging member and the mating component are separated, and the battery body and the mating component are in a second state; when the connecting rod and the rotation axis are arranged along a third direction, the engaging member and the mating component are engaged, and the battery body and the mating component are in a first state.

[0027] When switching between the second and first states, the handle can rotate at an angle not exceeding 90°. The handle has a small stroke, which can improve the switching efficiency.

[0028] Secondly, this application provides an electrical device including a battery compartment and a battery pack according to any embodiment of the first aspect. The battery compartment includes a mating component and a second connector, and at least a portion of the battery pack is housed within the battery compartment. The battery body and the mating component are in a first state, and the first connector and the second connector are connected.

[0029] By rotating the handle, the first and second states can be switched, thereby simplifying the battery pack assembly and disassembly process and improving its efficiency. This embodiment also integrates the handle rotation with the connection between the first and second connectors, further enhancing the battery pack assembly and disassembly efficiency.

[0030] In some embodiments, the battery compartment includes a first wall, and a mating component is connected to the first wall and located between the first wall and a second connector. The first connector is configured to be mated to the second connector.

[0031] The mating component is positioned close to the second connector. When the mating component engages with the handle, it can increase the force transmitted to the first and second connectors, thereby improving the stability of the connection between the first and second connectors.

[0032] In some embodiments, the mating component is detachably connected to the first wall. Attached Figure Description

[0047] Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this application, but not all embodiments.

[0049] The terms "first," "second," etc., used in the specification, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy. In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments.

[0050] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0051] In the description of this application, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0052] In the embodiments of this application, "parallel" includes not only the case of absolute parallelism, but also the case of approximate parallelism as commonly understood in engineering; similarly, "perpendicular" also includes not only the case of absolute perpendicularity, but also the case of approximate perpendicularity as commonly understood in engineering. For example, if the angle between two directions is 80°-90°, the two directions can be considered perpendicular; if the angle between two directions is 0°-10°, the two directions can be considered parallel.

[0053] The battery pack of this application is described below with reference to the accompanying drawings.

[0054] Reference Figures 1 to 7The battery pack 1000 of this embodiment includes a battery body 1 and a handle 2. The battery body 1 includes a first connector 13. The handle 2 is rotatably connected to the battery body 1, and the handle 2 is configured to switch the battery body 1 and the mating part 2100 of the electrical device between a first state and a second state by rotation. In the first state, the first connector 13 and the second connector 2400 of the electrical device are connected. In the second state, the battery body 1 and the mating part 2100 are disconnected.

[0055] In this embodiment, the handle 2 facilitates the user's lifting and transport of the battery pack 1000. The handle 2 secures the battery body 1 to the mating component 2100, reducing the risk of separation between the first connector 13 and the second connector 2400 when the electrical equipment is subjected to external impact, thus improving safety and reliability. When installing the battery pack 1000, the handle 2 can be rotated to secure the battery body 1 to the mating component 2100; when removing the battery pack 1000, rotating the handle 2 releases the secure relationship between the battery body 1 and the mating component 2100; rotating the handle 2 switches between the first and second states, thereby simplifying the installation and removal of the battery pack 1000 and improving its efficiency. This embodiment also integrates the rotation of the handle 2 with the connection of the first connector 13 and the second connector 2400, further improving the installation and removal efficiency of the battery pack 1000.

[0056] In some embodiments, the first direction X, the second direction Z, and the third direction Y are perpendicular to each other.

[0057] In some embodiments, the battery body 1 includes a first housing 11, a second housing 2, and a cell module (not shown). The first housing 11 and the second housing 12 enclose a receiving cavity, and the cell module is housed in the receiving cavity, thereby improving the stability of the connection between the first connector 13 and the second connector 2400 of the electrical device.

[0058] In some embodiments, the battery module includes multiple battery cells, which can be connected in series, parallel, or a combination thereof. A combination thereof means that some of the multiple battery cells are connected in series and others in parallel. The battery cells can be lithium-ion cells, sodium-lithium-ion cells, sodium-ion cells, magnesium-ion cells, or other types of cells, and this application embodiment is not limited in this regard. Optionally, the battery cells are pouch cells.

[0059] In some embodiments, the battery body 1 further includes a circuit board (not shown), which is disposed within the receiving cavity and electrically connected to the cell module.

[0060] In some embodiments, the first connector 13 is electrically connected to the battery cell module and the circuit board. The battery cell module can provide power to the device through the first connector 13, and an external power source can also charge the battery cell module through the first connector 13. The circuit board can transmit electrical signal information (such as voltage, current, temperature, etc.) to the device through the first connector 13, so that the device can monitor the operating status of the battery pack 1000 in real time.

[0061] In some embodiments, there are two first connectors 13. One first connector 13 is electrically connected to the positive output terminal of the battery cell module, and the other first connector 13 is electrically connected to the negative output terminal of the battery cell module.

[0062] In some embodiments, two first connectors 13 are respectively disposed on opposite sides of the second housing 12.

[0063] In some embodiments, the first connector 13 is connected to the first housing 11.

[0064] In some embodiments, the first connector 13 may be a socket connector or a plug connector.

[0065] In some embodiments, the first connector 13 is a socket connector, and the second connector 2400 is a plug connector. The first connector 13 and the second connector 2400 are mated together.

[0066] In some embodiments, when in the first state, the battery body 1 is fixed to the mating component 2100 by the handle 2.

[0067] In some embodiments, the handle 2 is detachably connected to the battery body 1. The handle 2 can be quickly replaced when needed, reducing the maintenance cost of the battery pack 1000.

[0068] Reference Figures 1 to 11 The handle 2 includes two rotating arms 21, a connecting rod 22, and at least one engaging member 23. Along a first direction X, the two rotating arms 21 are respectively disposed on both sides of the battery body 1 and rotatably connected to the battery body 1. The first direction X is parallel to the rotation axis L of the handle 2. The connecting rod 22 connects the two rotating arms 21. The engaging member 23 is disposed on the rotating arms 21 and is used to engage with the mating component 2100 in a first state.

[0069] The rotation axis L of handle 2 is a virtual straight line, and each part of handle 2 can rotate around the rotation axis L.

[0070] When installing the battery pack 1000, the user can push the connecting rod 22, which drives the locking member 23 to rotate around the rotation axis L via the rotating arm 21, so that the locking member 23 engages with the mating part 2100; under the engagement of the locking member 23 and the mating part 2100, the battery body 1 is fixed to the mating part 2100.

[0071] When it is necessary to remove the battery pack 1000, the user can push the connecting rod 22 in the opposite direction. The connecting rod 22 drives the locking part 23 to rotate around the rotation axis L through the rotating arm 21, so as to release the locking part 23 from the engagement part 2100, thereby releasing the battery body 1 from the engagement part 2100. The user can then remove the battery pack 1000 by grabbing the connecting rod 22.

[0072] By setting two rotating arms 21, the stability of the connection between the handle 2 and the battery body 1 can be improved, and the risk of failure of the connection between the handle 2 and the battery body 1 when transporting the battery pack 1000 can be reduced.

[0073] This application does not limit the engagement method between the engaging component 23 and the mating component 2100.

[0074] In some embodiments, the engaging member 23 is provided with a slot 234 for engaging with the mating member 2100. In a first state, the mating member 2100 can be inserted into the slot 234 to engage with the engaging member 23. In other alternative embodiments, the mating member 2100 is provided with a slot (not shown); in the first state, the engaging member 23 is inserted into the slot of the mating member 2100 to engage with the mating member 2100.

[0075] In some embodiments, the handle 2 includes two locking members 23, which are respectively connected to two rotating arms 21.

[0076] For example, the electrical equipment has two mating parts 2100 and two engaging parts 23 for engaging with the two mating parts 2100 respectively.

[0077] By setting two engaging parts 23, the engaging strength between the handle 2 and the mating part 2100 can be increased, the stability of the battery pack 1000 can be improved, the risk of separation between the first connector 13 and the second connector 2400 can be reduced when the electrical equipment is subjected to external impact, and the safety and reliability can be improved.

[0078] In some embodiments, the engaging member 23 is detachably connected to the rotating arm 21. The engaging member 23 is used to engage with the mating component 2400, and is at higher risk of damage. In the event of damage to the engaging member 23, this embodiment of the application can replace the engaging member 23 without replacing the entire handle 2, thereby reducing the maintenance cost of the battery pack 1000.

[0079] In some embodiments, the engaging member 23 is detachably connected to the rotating arm 21 by a fastener 3. Optionally, the fastener 3 includes a bolt.

[0080] In some embodiments, the rotating arm 21 is connected to the battery body 1 via a rotating shaft 4. Exemplarily, the rotating shaft is detachably connected to the battery body 1, and the rotating arm 21 is rotatably connected to the rotating shaft 4.

[0081] In some embodiments, when viewed along the first direction X, the distance D1 between the connecting rod 22 and the rotation axis L is greater than the distance D2 between the engaging member 23 and the rotation axis L.

[0082] During the process of engaging or disengaging the engaging member 23 with the mating component 2100, the engaging member 23 will be subject to resistance. According to the torque balance, the greater the distance between the connecting rod 22 and the rotation axis L, the less force the user needs to apply when rotating the handle 2; the embodiment of this application reduces the force required for the user to rotate the handle 2, making it easier for the user to switch between the first state and the second state.

[0083] In some embodiments, the engaging member 23 includes an engaging body 231, a first engaging arm 232, and a second engaging arm 233, the first engaging arm 232 and the second engaging arm 233 protruding from the same side of the engaging body 231. The first engaging arm 232 is located on the side of the second engaging arm 233 closer to the rotation axis L, and a groove 234 is formed between the first engaging arm 232 and the second engaging arm 233.

[0084] When the mating component 2100 is inserted into the slot 234, the first locking arm 232 and the second locking arm 233 can limit the mating component 2400 from both sides.

[0085] In some embodiments, the rotating arm 21 is provided with a recess 211, in which at least a portion of the engaging body 231 and at least a portion of the first engaging arm 232 are accommodated.

[0086] The recess 211 serves a positioning function during the assembly of the rotating arm 21 and the engaging component 23, simplifying the assembly process. By providing the recess 211, the weight of the handle 2 can be reduced, thus decreasing the overall space occupied by the handle 2. Furthermore, the recess 211 reduces the distance between the engaging component 23 and the rotation axis L, thereby reducing the resistance torque when rotating the handle 2.

[0087] In some embodiments, the engaging body 231 is connected to the rotating arm 21 by a fastener 3. Optionally, the engaging body 231 is provided with a threaded hole, and the fastener 3 is threadedly engaged with the engaging body 231.

[0088] In some embodiments, in the direction away from the engaging body 231, the second engaging arm 233 extends by a greater dimension than the first engaging arm 232 extends.

[0089] When the handle 2 is rotated, the portion of the second engaging arm 233 that extends beyond the first engaging arm 232 can guide the mating component 2400 into the slot 234.

[0090] In some embodiments, the size of the battery body 1 along the first direction X is greater than the size of the battery body 1 along the third direction Y, and the size of the battery body 1 along the second direction Z is greater than the size of the battery body 1 along the third direction Y.

[0091] In some embodiments, the rotating arm 21 is rotatably connected to the end of the battery body 1 along the second direction Z.

[0092] By rotatably connecting the rotating arm 21 to the end of the battery body 1 along the second direction Z, the size requirements of the rotating arm 21 can be reduced, and the weight of the handle 2 can be reduced.

[0093] In some embodiments, the dimension of the connecting rod 22 along the first direction X is greater than the dimension of the battery body 1 along the first direction X and greater than the dimension of the battery body 1 along the third direction Y.

[0094] In some embodiments, such as Figure 6 and Figure 7 As shown, the handle 2 is configured such that when the connecting rod 22 and the rotation axis L are arranged along the second direction Z, the engaging member 23 is separated from the mating part 2100, and the battery body 1 and the mating part 2100 are in the second state.

[0095] like Figure 4 and Figure 5 As shown, the handle 2 is configured such that when the connecting rod 22 and the rotation axis L are arranged along the third direction Y, the engaging member 23 engages with the mating part 2100, and the battery body 1 and the mating part 2100 are in the first state.

[0096] In this embodiment, when switching between the second and first states, the handle 2 can rotate at an angle not exceeding 90°. The handle 2 has a small stroke, which can improve the switching efficiency.

[0097] This application also provides an electrical device, which includes a battery pack 1000 and a battery compartment 2000 provided in any of the foregoing embodiments. The battery compartment 2000 includes a mating component 2100 and a second connector 2400, and at least a portion of the battery pack 1000 is housed within the battery compartment 2000. The battery body 1 and the mating component 2100 are in a first state, and the first connector 13 and the second connector 2400 are connected.

[0098] When installing the battery pack 1000, first insert the battery pack 1000 into the battery compartment 2000, and then fix the battery body 1 to the mating part 2100 by rotating the handle 2, thereby fixing the battery body 1 to the battery compartment 2000; when removing the battery pack 1000, rotate the handle 2 to release the fixed relationship between the battery body 1 and the mating part 2100, and the user can pull the handle 2 to take the battery body 1 out of the battery compartment 2000.

[0099] In this embodiment, rotating the handle 2 allows switching between the first and second states, thereby simplifying the assembly and disassembly of the battery pack 1000 and improving its efficiency. This embodiment also integrates the rotation of the handle 2 with the connection between the first connector 13 and the second connector 2400, further enhancing the assembly and disassembly efficiency of the battery pack 1000.

[0100] The electrical equipment used in the embodiments of this application can be portable devices, laptops, electric toys, drones, power tools, energy storage systems, etc. Power tools include metal cutting power tools, cleaning tools, etc., such as electric drills, electric wrenches, vacuum cleaners, robot vacuum cleaners, etc. The embodiments of this application do not impose any special limitations on the above-mentioned electrical equipment.

[0101] In some embodiments, the electrical equipment may be a drone. Optionally, the electrical equipment may be an agricultural drone.

[0102] In some embodiments, the mating component 2100 may be a cylindrical component to facilitate engagement with the engaging component 23.

[0103] In some embodiments, the battery compartment 2000 includes a frame 2200, which includes two first walls 2210 and two second walls 2220. The two first walls 2210 are disposed opposite each other along a first direction X, and the two second walls 2220 are disposed opposite each other along a third direction Y. Each second wall 2220 is connected to the two first walls 2210.

[0104] Two first walls 2210 and two second walls 2220 form an opening 2230, through which the battery pack 1000 can be inserted into the interior of the frame 2200.

[0105] The mating component 2100 is positioned close to the second connector 2400. When the mating component 2100 engages with the handle 2, it can increase the force transmitted to the first connector 13 and the second connector 2400, thereby improving the stability of the connection between the first connector 13 and the second connector 2400.

[0106] In some embodiments, the mating component 2100 is detachably connected to the first wall 2210 so that the mating component 2100 can be replaced when the first wall 2210 is worn.

[0107] In some embodiments, there are two mating parts 2100, and the two mating parts 2100 are respectively connected to the two first walls 2210.

[0108] In some embodiments, the battery compartment 2000 further includes two guide protrusions 2300, which are respectively protruding from the inner surfaces of the two first walls 2210.

[0109] The second housing 12 has guide recesses 121 on both sides along the first direction X. Two guide protrusions 2300 are respectively inserted into the two guide recesses 121 of the second housing 12.

[0110] The cooperation between the guide protrusion 2300 and the guide recess 121 can guide the battery pack 1000 to be inserted into the frame 2200, which helps the first connector 13 and the second connector 2400 to be inserted along the second direction Z, improves assembly accuracy, and reduces the risk of connector damage.

[0111] In some embodiments, there are two second connectors 2400. One second connector 2400 is disposed at one end of a guide protrusion 2300 in the opposite direction of the second direction Z, and the other second connector 2400 is disposed at one end of another guide protrusion 2300 in the opposite direction of the second direction Z.

[0112] In some embodiments, in the second direction Z, a gap G is provided between the mating member 2100 and the guide protrusion 2300, which can avoid the second engaging arm 233 of the engaging member 23.

[0113] In some embodiments, such as Figure 4 and Figure 5 As shown, in the first state, the mating component 2100 is inserted into the slot 234 of the engaging component 23 to engage with it. At this time, the extension direction of the rotating arm 21 is parallel to the third direction Y. Of course, the extension direction of the rotating arm 21 may also have a certain angle with the third direction Y.

[0114] For example, in the first state, the swing arm 21 extends approximately along a third direction Y.

[0115] In some embodiments, when in the first state, the frame 2200 can limit the battery body 1 from the first direction X and the third direction Y, and the cooperating component 2100 can limit the battery body 1 from the second direction Z through the handle 2, thereby fixing the battery body 1 in the battery compartment 2000.

[0116] In some embodiments, such as Figure 6and Figure 7 As shown, in the second state, the mating component 2100 disengages from the slot 234 of the engaging component 23, and the engagement relationship between the mating component 2100 and the engaging component 23 is released. At this time, the extension direction of the rotating arm 21 is parallel to the second direction Z. Of course, the extension direction of the rotating arm 21 may also have a certain angle with the second direction Z.

[0117] For example, in the second state, the rotating arm 21 extends generally along the second direction Z.

[0118] In some embodiments, when in the second state, the cooperating component 2100 releases the restriction on the battery body 1 in the second direction Z, and the battery body 1 can be pulled out of the battery compartment 2000 by pulling the handle 2 along the second direction Z.

[0119] Although this application has been described with reference to preferred embodiments, various modifications can be made thereto and components can be replaced with equivalents without departing from the scope of this application. In particular, the technical features mentioned in the various embodiments can be combined in any manner, provided there is no structural conflict. This application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
