[0002] This application claims priority to Chinese patent application 202421595318.4 entitled "Battery and Electrical Device", filed on July 8, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of battery technology, and more specifically, to a battery and an electrical device. Background Technology

[0004] With technological advancements, the battery industry has developed rapidly, leading to a significant increase in the market share and usage frequency of electrical devices. Electric vehicles, such as electric cars, are increasingly appearing in various applications. To improve the convenience of electrical devices, especially electric vehicles, battery swapping stations for rapid battery replacement have emerged. However, electrical devices frequently require battery swapping. During this process, a locking mechanism can be installed on the device and on the battery. The battery's locking mechanism needs to engage or disengage with the device's locking mechanism to securely fasten or detach the battery. However, the battery's locking mechanism is susceptible to damage from external environmental impurities (dust, water, etc.), which can cause it to malfunction and hinder the assembly and disassembly of the battery and device.

[0005] Summary of the Invention

[0006] This application provides a battery and an electrical device that facilitates the assembly and disassembly of the battery and the electrical device.

[0007] In a first aspect, embodiments of this application provide a battery for use in electrical equipment. The electrical equipment has a lock base. The battery includes a battery cell, a housing, a locking mechanism, and a sealing element. The housing is used to accommodate the battery cell and has an installation cavity and a lead-out hole, with the lead-out hole communicating with the installation cavity. The locking mechanism includes a sleeve and a locking element. The sleeve is fixed in the installation cavity and sleeved on the locking element. The locking element partially extends out of the sleeve and passes through the lead-out hole. The locking element is used to engage or disengage with the lock base. The sealing element is at least partially located between the hole wall of the lead-out hole and the outer surface of the locking element.

[0008] In the above technical solution, the sleeve is fixed inside the mounting cavity, which can hide the sleeve inside the housing and reduce the impact of the external environment on the sleeve. Since the locking element extends out of the sleeve and through the outlet hole, impurities from the external environment can easily enter the mounting cavity and the sleeve through the gap between the hole wall and the outer surface of the locking element, easily clogging the sleeve and causing the locking mechanism to fail. By setting the locking element at least partially between the hole wall and the outer surface of the locking element, the seal can block impurities from entering the mounting cavity and the sleeve, thereby reducing the impact of impurities on the engagement or disengagement of the locking element and the lock seat, thus reducing the risk of locking mechanism failure and facilitating the assembly and disassembly of the battery and electrical equipment.

[0009] In some embodiments, the locking member is movably disposed on the sleeve along the extension direction of the outlet hole. Along the extension direction of the outlet hole, the locking member has a first position engaged with the lock seat and a second position disengaged from the lock seat. When the locking member is in the first position and when the locking member is in the second position, at least a portion of at least one seal is located between the hole wall surface of the outlet hole and the outer surface of the locking member. As the locking member moves along the extension direction of the outlet hole, by providing at least a portion of at least one seal between the hole wall surface of the outlet hole and the outer surface of the locking member, the risk of impurities entering the mounting cavity and sleeve through the gap between the hole wall surface of the outlet hole and the outer surface of the locking member is reduced when the locking member switches between the first position, the second position, or between the first and second positions. This reduces the risk of locking member failure and facilitates the assembly and disassembly of the battery and electrical equipment.

[0010] In some embodiments, the locking member includes a lock head. When the locking member is in a first position, the lock head cooperates with the housing to clamp the lock seat for engagement. When the locking member is in a second position, the distance between the lock head and the housing is greater than the distance between the lock head and the housing when the locking member is in the first position. By clamping the lock seat with the lock head and housing, the connection between the battery and the lock seat is made more stable, reducing the risk of the battery shaking on the lock seat. When the locking member switches from the first position to the second position, the lock head moves away from the housing, causing the lock head and housing to release their clamping grip on the lock seat, facilitating the disengagement of the locking member and the lock seat.

[0011] In some embodiments, the locking member can move from a first position to a second position along the direction extending from the sleeve; multiple seals are arranged along the extension direction of the outlet hole, and when the locking member is in the first position, all seals are at least partially located between the hole wall of the outlet hole and the outer surface of the locking member. In the first position, the locking member can engage with the lock seat to lock the battery and the lock seat. The fact that all seals are at least partially located between the hole wall of the outlet hole and the outer surface of the locking member enables multi-layer sealing of the gap between the hole wall of the outlet hole and the outer surface of the locking member, thereby improving the sealing effect between the hole wall of the outlet hole and the outer surface of the locking member and reducing the risk of impurities entering the mounting cavity and sleeve through the gap.

[0012] In some embodiments, the plurality of seals includes a first seal and a second seal, which are spaced apart along the extension direction of the outlet hole. The first seal is closer to the mounting cavity than the second seal. When the locking member is in the second position, at least a portion of the first seal is located between the hole wall of the outlet hole and the outer surface of the locking member, while the second seal is located outside the outlet hole. When the locking member is in the first position, all seals can seal the gap, and when the locking member is in the second position, the second seal is located outside the outlet hole. During the process of the locking member switching from the first position to the second position, the second seal can also carry away some impurities from the outlet hole to clean the impurities at the outlet hole, thereby reducing the risk of impurities entering the mounting cavity and sleeve.

[0013] In some embodiments, when the locking member is in the second position, a portion of the first seal is located outside the outlet hole. When the locking member switches from the first position to the second position, a portion of the first seal inside the outlet hole moves out of the outlet hole to draw out impurities from the outlet hole, facilitating the cleaning of impurities in the gap and reducing the risk of impurities entering the mounting cavity and sleeve.

[0014] In some embodiments, when the locking member is in the first position, a portion of the second seal is located outside the outlet hole, and another portion is located inside the outlet hole, to seal the gap. When the locking member is in the first position, the second seal, with a portion outside the outlet hole, can prevent impurities from entering the gap, thereby reducing the risk of impurities entering the mounting cavity and sleeve.

[0015] In some embodiments, a guide structure is provided between the sleeve and the locking member. The guide structure is configured to guide the locking member to rotate about a first axis as it moves between a first position and a second position along the extension direction of the outlet hole, so that the locking member engages or disengages from the lock seat. The first axis is parallel to the extension direction of the outlet hole. By providing a guide structure to guide the movement of the locking member, the movement of the locking member is made smoother, and the rotation of the locking member to engage or disengage from the lock seat makes engagement more convenient.

[0016] In some embodiments, the guide structure includes a limiting groove disposed on the inner circumferential surface of the sleeve and a protrusion disposed on the outer circumferential surface of the locking member, with at least a portion of the protrusion accommodated within the limiting groove. By providing a limiting groove on the inner circumferential surface of the sleeve and a protrusion on the outer circumferential surface of the locking member to guide the locking member, the machining of the guide structure becomes more convenient.

[0017] In some embodiments, the limiting groove includes a first groove segment, a second groove segment, and a third groove segment connected in sequence. The first groove segment and the third groove segment both extend along the extension direction of the lead-out hole. The first groove segment and the third groove segment are arranged at intervals along the circumference of the locking member and at intervals along the extension direction of the lead-out hole. Along the extension direction of the lead-out hole, the first groove segment penetrates one side of the telescopic member extending out of the sleeve. When the locking member is in a first position, the protrusion is located in the third groove segment. When the locking member is in a second position, the protrusion is located in the first groove segment.

[0018] In the above technical solution, by setting the first and third groove segments of the limiting groove to extend along the extension direction of the lead-out hole, and the first and third groove segments are spaced apart in both the extension direction of the lead-out hole and the circumferential direction of the locking member, the second groove segment is a spiral groove connecting the first and third groove segments. This allows the protrusion of the locking member to move only along the first direction following the extension direction of the first and second groove segments when it is located in the first and third groove segments. Furthermore, when the protrusion of the locking member is located in the second groove segment, it can both rotate relative to the sleeve and move relative to the sleeve along the first direction, thereby limiting the rotation angle of the locking member and enabling it to move between the first and second positions along the extension direction of the lead-out hole.

[0019] In some embodiments, the battery further includes an adjusting member rotatably disposed on the sleeve about a first axis, and the adjusting member is threadedly connected to the locking member. By adjusting the locking member relative to the sleeve, the locking member is moved between a first position and a second position, thereby enabling the locking member to engage or disengage from the lock seat.

[0020] In some embodiments, the limiting groove extends to the end of the sleeve near the outlet hole. By providing the limiting groove to the end of the sleeve near the outlet hole, it is beneficial to insert the locking member with the protrusion into the sleeve, facilitating the engagement between the locking member and the sleeve.

[0021] In some embodiments, the locking member is provided with a first annular groove, which surrounds the locking member around a first axis. The sealing member is sleeved on the locking member and engaged within the first annular groove. The first axis is parallel to the extending direction of the outlet hole. By providing the first annular groove in the locking member, the sealing member can be engaged within the first annular groove, which facilitates the installation of the sealing member and reduces the risk of the sealing member falling off the first locking member.

[0022] In some embodiments, the seal is sleeved on the locking member, and the outer peripheral surface of the seal is provided with a second annular groove surrounding the locking member. By providing the second annular groove, the contact area between the seal and the hole wall surface of the outlet hole can be reduced, thereby reducing the risk of seal damage due to excessive friction between the seal and the hole wall surface.

[0023] In some embodiments, there are multiple second annular grooves, which are spaced apart along the extension direction of the outlet hole. Multiple second annular grooves allow a single seal to form a multi-stage seal at the gap, resulting in a more stable seal.

[0024] In some embodiments, the locking element includes a locking rod and a locking head. One end of the locking rod is located inside a sleeve, and the locking head is connected to the other end of the locking rod. The locking rod passes through a lead-out hole, and the locking head is used to engage with a lock seat. The locking rod is partially thickened to form a thickened section, and a gap is formed between the outer circumferential surface of the thickened section and the wall surface of the lead-out hole. A sealing element is disposed in the thickened section. By placing the sealing element in the thickened section, the material used for the sealing element can be reduced, the risk of damage to the sealing element can be decreased, and the sealing performance of the sealing element can be improved.

[0025] Secondly, embodiments of this application provide an electrical device including a lock base and a battery provided in any of the embodiments of the first aspect. The locking element is configured to engage or disengage from the lock base.

[0026] In some embodiments, the electrical device is a vehicle, the vehicle including a mounting bracket, the mounting bracket being provided with a locking seat, a locking member engaging with the locking seat to connect a battery to the mounting bracket, and the locking member disengaging from the locking seat to allow the battery to be disconnected from the mounting bracket.

[0045] In the description of the embodiments of this application, unless otherwise expressly specified and limited, technical terms such as "installation," "connection," "joining," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; 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. For those skilled in the art, the specific meaning of the above terms in the embodiments of this application can be understood according to the specific circumstances.

[0046] In this application, "multiple" refers to two or more (including two), and similarly, "multiple groups" refers to two or more (including two), and "multiple pieces" refers to two or more (including two).

[0047] In this embodiment of the application, the battery cell can be a secondary battery, which refers to a battery cell that can be recharged to activate the active materials and continue to be used after the battery cell has been discharged.

[0048] Battery cells include, but are not limited to, lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, etc.

[0049] The battery mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity.

[0050] In some embodiments, the battery can be a battery module, and when there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0051] In some embodiments, the battery can be a battery pack, which includes a housing and individual battery cells, with the individual battery cells or battery modules housed within the housing.

[0052] In some embodiments, the housing may be part of the vehicle's chassis structure. For example, a portion of the housing may be at least a part of the vehicle's floor, or a portion of the housing may be at least a part of the vehicle's crossbeams and longitudinal beams.

[0053] In some embodiments, the battery can be an energy storage device. Energy storage devices include energy storage containers, energy storage cabinets, etc.

[0054] With technological advancements, new energy vehicles are developing rapidly, and the market share and usage frequency of electric vehicles are increasing. Electric commercial vehicles, such as electric heavy-duty trucks and electric light-duty trucks, are gradually appearing in various application scenarios, and battery swapping stations for these electric trucks are being built to match them.

[0055] In the field of new energy vehicles, electric trucks consume more energy than ordinary passenger cars due to their heavy loads and long driving ranges. Therefore, in order to achieve extended range, electric trucks need to frequently perform battery swapping. During the battery swapping process, the locking and detachment of the battery from the vehicle is particularly important.

[0056] To lock and detach the battery from the vehicle, a locking mechanism can be installed on the battery. This mechanism includes a sleeve and a locking element. The locking element engages with the sleeve to lock the battery to the vehicle or detach it. To reduce the impact of the external environment on the sleeve and facilitate battery assembly, the sleeve can be concealed within the battery housing. The locking element partially extends from the sleeve and through the housing, allowing it to contact the vehicle's locking seat for engagement or disengagement. However, during use, impurities (dust, water, etc.) from the external environment can easily enter the housing through the protruding part of the locking element, affecting the normal operation of the locking mechanism. This can make it difficult for the locking mechanism to move and lock or detach the battery from the vehicle, leading to malfunction of the locking mechanism and rendering the battery unusable, thus hindering the installation and removal of the battery from the electrical equipment.

[0057] To facilitate the connection and disconnection of batteries and electrical devices, this application provides a battery comprising a locking mechanism, a housing, and individual battery cells. The individual battery cells are housed within the housing. The housing has an interconnected mounting cavity and a lead-out hole. The locking mechanism includes a sleeve and a locking member. The sleeve is disposed in the mounting cavity, and the locking member partially extends out of the sleeve and passes through the lead-out hole. The locking member is configured to engage or disengage with a lock seat, and a seal is configured to seal the gap between the wall surface of the lead-out hole and the outer surface of the locking member.

[0058] By sealing the gap with a sealant, the influence of impurities in the external environment on the locking mechanism can be reduced, the risk of locking mechanism failure can be reduced, and it is beneficial for the disassembly and assembly of batteries and electrical equipment.

[0059] The batteries described in the embodiments of this application are applicable to electrical devices that use batteries.

[0060] Electrical equipment can include vehicles, mobile phones, portable devices, laptops, ships, spacecraft, electric toys, and power tools, etc. Vehicles can be gasoline-powered cars, natural gas-powered cars, or new energy vehicles; new energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. Spacecraft include airplanes, rockets, space shuttles, and spacecraft, etc. Electric toys include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Power tools include metal cutting power tools, grinding power tools, assembly power tools, and railway power tools, such as electric drills, electric grinders, electric wrenches, electric screwdrivers, electric hammers, impact drills, concrete vibrators, and electric planers, etc.

[0061] For ease of explanation, the following embodiments use a vehicle as an example of electrical equipment.

[0062] Please refer to Figure 1, which is a structural schematic diagram of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline vehicle, a natural gas vehicle, or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle, or a range-extended electric vehicle, etc. A battery 100 is provided inside the vehicle 1000. The battery 100 can be located at the bottom, front, or rear of the vehicle 1000.

[0063] According to some embodiments of this application, referring to FIG2, FIG2 is a partial structural schematic diagram of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 has a mounting bracket 200 and a lock seat 300, the lock seat 300 being mounted on the mounting bracket 200. The battery 100 includes a locking mechanism 10, which is used to lock or unlock with the lock seat 300 to realize battery swapping of the vehicle 1000. The battery 100 can be used to supply power to the vehicle 1000, for example, the battery 100 can be used as an operating power source or a power source for the vehicle 1000.

[0064] Optionally, as shown in Figure 1, the vehicle 1000 may also include a controller 400 and a motor 500. The controller 400 is used to control the battery 100 to supply power to the motor 500, for example, to meet the power requirements of the vehicle 1000 during startup, navigation, and driving.

[0065] In some embodiments of this application, the battery 100 can not only serve as the operating power or power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0066] Referring to Figure 2, and further referring to Figure 3, which is an exploded view of the structure of a battery 100 provided in some embodiments of this application. The battery 100 also includes a housing 20, and a locking mechanism 10 (not shown in Figure 3) is mounted on the housing 20.

[0067] The housing 20 provides a receiving space 205 for the battery cell 30, and the housing 20 can adopt various structures. In some embodiments, the housing 20 may include a first portion 201 and a second portion 202, which overlap each other, and together define the receiving space 205 for accommodating the battery cell 30. Alternatively, both the first portion 201 and the second portion 202 may be hollow structures with one side open, with the open side of the first portion 201 overlapping the open side of the second portion 202, so that the first portion 201 and the second portion 202 together define the receiving space 205. Exemplarily, the sleeve 1 may be installed on either the first portion 201 or the second portion 202.

[0068] In other embodiments, the housing 20 can also have other structures. For example, the second part 202 can be a hollow structure with one end open, and the first part 201 can be a plate-like structure. The first part 201 covers the open side of the second part 202, so that the first part 201 and the second part 202 together define the receiving space 205. Of course, the housing 20 formed by the first part 201 and the second part 202 can be of various shapes, such as a cylinder, a cuboid, etc.

[0069] In the battery 100, there may be one or more battery cells 30 disposed within the housing 20. When there are multiple battery cells 30 disposed within the housing 20, they may be connected in series, in parallel, or in a mixed configuration. A mixed configuration means that some of the battery cells 30 are connected in series and others in parallel. Multiple battery cells 30 may be directly connected in series, in parallel, or in a mixed configuration, and then the entire assembly of the multiple battery cells 30 is housed within the housing 20. Alternatively, the battery 100 may be composed of multiple battery cells 30 first connected in series, in parallel, or in a mixed configuration to form a battery module, and then these modules are connected in series, in parallel, or in a mixed configuration to form a whole, which is then housed within the housing 20. In some embodiments, the battery 100 may also include other structures. For example, the battery 100 may also include a busbar component for connecting multiple battery cells 30 to achieve electrical connection between them.

[0070] Each battery cell 30 can be a secondary battery 100 or a primary battery 100; it can also be a lithium-sulfur battery 100, a sodium-ion battery 100, or a magnesium-ion battery 100, but is not limited to these. The battery cell 30 can be cylindrical, flat, cuboid, or other shapes.

[0071] In some embodiments of this application, please refer to Figures 4 and 5. Figure 4 is an assembly diagram of the locking mechanism 10 and the sealing member 40 provided in some embodiments of this application; Figure 5 is a structural schematic diagram of the locking member 2 located in the first position provided in some embodiments of this application. This application provides a battery 100, including a battery cell 30, a housing 20, a locking mechanism 10, and a sealing member 40. The housing 20 is used to accommodate the battery cell 30, and the housing 20 is provided with a mounting cavity 203 and a lead-out hole 204, the lead-out hole 204 communicating with the mounting cavity 203. The locking mechanism 10 includes a sleeve 1 and a locking member 2. The sleeve 1 is fixed inside the mounting cavity 203, and the sleeve 1 is sleeved on the locking member 2. The locking member 2 partially extends out of the sleeve 1 and passes through the lead-out hole 204. The locking member 2 is used to engage or disengage with a lock seat 300. The sealing member 40 is at least partially located between the hole wall of the lead-out hole 204 and the outer surface of the locking member 2.

[0072] The mounting cavity 203 of the housing 20 can be a receiving space 205 of the housing 20, with the sleeve 1 and the battery cell 30 both fixed inside the mounting cavity 203; alternatively, the mounting cavity 203 and the receiving space 205 of the housing 20 can be two independent cavities. For example, the receiving space 205 has a cavity wall, and the mounting cavity 203 can be disposed within the cavity wall, with the sleeve 1 fixed inside the mounting cavity 203 and the battery cell 30 located inside the receiving space 205. The mounting cavity 203 can be a cavity with openings at both ends, one opening being a lead-out hole 204, and the other opening for inserting the sleeve 1 to fix the sleeve 1 to the mounting cavity 203. The sleeve 1 can be welded to the mounting cavity 203 to achieve fixation of the sleeve 1 to the mounting cavity 203; alternatively, the sleeve 1 can be detachably mounted to the mounting cavity 203 to achieve fixation of the sleeve 1 to the mounting cavity 203, for example, the sleeve 1 and the mounting cavity 203 can be detachably connected by bolts.

[0073] As an example, the mounting cavity 203 is a cavity structure independent of the accommodating space 205. The mounting cavity 203 has two openings, one of which is an outlet hole 204. The sleeve 1 has a sleeve body 11 and a mounting seat 12. The sleeve body 11 is located inside the mounting cavity 203, and the mounting seat 12 is installed at the other opening of the mounting cavity 203 by bolts.

[0074] A portion of the locking member 2 is located inside the sleeve 1, another portion is located inside the outlet hole 204, and a third portion extends out of the outlet hole 204 to engage with the lock seat 300, thereby enabling the locking member 2 to engage or disengage from the lock seat 300. The locking member 2 can be snapped into the lock seat 300 for engagement, or it can be inserted into the lock seat 300 for engagement. The locking member 2 can be movable relative to the sleeve 1 to facilitate engagement or disengagement with the lock seat 300; for example, the locking member 2 can rotate and / or move relative to the sleeve 1. The outlet hole 204 can be a circular hole, a polygonal hole, etc.

[0075] A gap 50 exists between the wall surface of the outlet hole 204 and the outer surface of the locking member 2. The sealing member 40 is a component used to seal the gap 50 between the wall surface of the outlet hole 204 and the outer surface of the locking member 2. The sealing member 40 may be disposed on the wall surface of the outlet hole 204; for example, the wall surface of the outlet hole 204 may have an annular groove, and the sealing member 40 may be engaged within the annular groove. Alternatively, the sealing member 40 may be disposed on the outer surface of the locking member 2; for example, the sealing member may be bonded to the outer surface of the locking member 2. The locking member 2 may rotate relative to the sleeve 1, and all sealing members 40 may seal the gap 50. Alternatively, the locking member 2 may move relative to the sleeve 1 along the outlet direction of the outlet hole 204, and the sealing members 40 may seal the gap 50. There may be only one sealing member 40 or multiple sealing members 40.

[0076] In embodiments where there is only one seal 40, the seal 40 may seal the gap 50 only when the locking member 2 is engaged with the lock seat 300; or the seal 40 may seal the gap 50 only when the locking member 2 is disengaged from the lock seat 300; or the seal 40 may seal the gap 50 both when the locking member 2 is engaged with and disengaged from the lock seat 300.

[0077] The seal 40 is at least partially located between the hole wall of the outlet hole 204 and the outer surface of the locking member 2. That is, when the seal 40 seals the gap 50, the entire seal 40 may be located between the hole wall of the outlet hole 204 and the outer surface of the locking member 2 to seal the gap; or only a portion of the seal 40 may be located between the hole wall of the outlet hole 204 and the outer surface of the locking member 2 to seal the gap 50, and the other portion of the seal 40 may be located outside the outlet hole 204.

[0078] In embodiments where there are multiple seals 40, all seals 40 may seal the gap 50 only when the locking member 2 is engaged with the lock seat 300; all seals 40 may seal the gap 50 only when the locking member 2 is disengaged from the lock seat 300; all seals 40 may seal the gap 50 both when the locking member 2 is engaged with and disengaged from the lock seat 300; or only some seals 40 may seal the gap 50 when the locking member 2 is engaged with or disengaged from the lock seat 300. When the seals 40 seal the gap 50, a portion of the seals 40 may be located outside the outlet hole 204, and another portion may be located between the hole wall of the outlet hole 204 and the outer surface of the locking member 2; or a portion of one of the multiple seals 40 may be located between the hole wall of the outlet hole 204 and the outer surface of the locking member 2 to seal the gap 50, while another portion may be located outside the outlet hole 204.

[0079] The sealing element can be a sealing ring fitted onto the locking element, and the material of the sealing element 40 can be nitrile rubber, fluororubber, silicone rubber, neoprene rubber, polytetrafluoroethylene, etc.

[0080] In this embodiment, the sleeve 1 is fixed inside the mounting cavity 203, and the mounting cavity 203 communicates with the outlet hole 204, allowing the sleeve 1 to communicate with the outside world. Since the locking member 2 extends out of the sleeve 1 and through the outlet hole 204, impurities from the external environment can easily enter the mounting cavity 203 and the sleeve 1 through the gap 50 between the hole wall of the outlet hole 204 and the outer surface of the locking member 2, potentially clogging the sleeve 1 and causing the locking mechanism 10 to fail. Sealing the gap 50 between the hole wall of the outlet hole 204 and the outer surface of the locking member 2 with the sealing member 40 reduces the amount of impurities entering the mounting cavity 203 and the sleeve 1 through the gap 50, thereby reducing the impact of impurities on the engagement or disengagement of the locking member 2 and the lock seat 300, and further reducing the risk of locking mechanism 10 failure. This facilitates the disassembly and assembly of the battery 100 and the electrical equipment.

[0081] In some embodiments, please refer to Figures 5 and 6. Figure 6 is a structural schematic diagram of the locking member 2 in a second position according to some embodiments of this application. The locking member 2 is movably disposed on the sleeve 1 along the extending direction X of the outlet hole 204. Along the extending direction of the outlet hole 204, the locking member 2 has a first position engaging with the lock seat 300 and a second position disengaging from the lock seat 300. When the locking member 2 is in the first position or the second position, at least a portion of at least one sealing member 40 is located between the hole wall surface of the outlet hole 204 and the outer surface of the locking member 2.

[0082] The locking member 2 can extend or retract from the sleeve 1 along the extension direction X of the outlet hole to switch the locking member 2 between the second position and the first position. Alternatively, the locking member 2 can extend, retract, and rotate along the extension direction X of the outlet hole to switch the locking member 2 between the second position and the first position.

[0083] Along the extension and retraction direction of the locking member 2, the locking member 2 can extend from the first position to the sleeve 1 to the second position, or the locking member 2 can extend from the second position to the sleeve 1 to the first position.

[0084] When the locking element 2 is in the first position, it can be that only one sealing element 40 seals the gap 50, or multiple sealing elements 40 can seal the gap 50. When the locking element 2 is in the second position, it can be that only one sealing element 40 seals the gap 50, or multiple sealing elements 40 can seal the gap 50.

[0085] When the locking member 2 is in the first position and when the locking member 2 is in the second position, at least a portion of at least one sealing member 40 is located between the hole wall of the outlet hole 204 and the outer surface of the locking member 2 to seal the gap.

[0086] In the above embodiments, when the locking member 2 moves along the extension direction X of the lead-out hole, at least one sealing member 40 is provided to seal the gap 50, so that the sealing member 40 seals the gap 50 when the locking member 2 switches between the first position, the second position, or between the first position and the second position. This reduces the risk of impurities entering the mounting cavity 203 and the sleeve 1 through the gap 50, thereby reducing the risk of the locking member 2 failing and facilitating the disassembly and assembly between the battery 100 and the electrical equipment.

[0087] In some embodiments, the locking member 2 includes a lock head 22. When the locking member 2 is in a first position, the lock head 22 cooperates with the housing 20 to clamp the lock seat 300 to engage with the lock seat 300. When the locking member 2 is in a second position, the distance between the lock head 22 and the housing 20 is greater than the distance between the lock head 22 and the housing 20 when the locking member 2 is in the first position.

[0088] When the locking member 2 switches from the first position to the second position, the locking head 22 of the locking member 2 extends away from the sleeve 1, which increases the distance between the locking head 22 and the housing 20, thereby causing the locking member 2 to disengage from the lock seat 300.

[0089] The locking head 22 and the housing 20 work together to clamp the lock seat 300, making the connection between the battery 100 and the lock seat 300 more stable and reducing the risk of the battery 100 shaking on the lock seat 300. When the locking member 2 switches from the first position to the second position, the locking head 22 moves away from the housing 20, causing the locking head 22 and the housing 20 to release their clamping of the lock seat 300, making it easier to disengage the locking member 2 from the lock seat 300.

[0090] In some embodiments, the locking member 2 can move from the first position to the second position along the direction of extending from the sleeve 1. There are multiple seals 40 arranged along the extension direction X of the outlet hole. When the locking member 2 is in the first position, all seals 40 seal the gap 50.

[0091] It is possible that when the locking member 2 switches from the first position to the second position, some of the seals 40 release the seal on the gap 50, while the other part of the seals 40 maintains the seal on the gap 50; or it is possible that when the locking member 2 switches from the first position to the second position, all the seals 40 maintain the seal on the gap 50.

[0092] It can be that two adjacent seals 40 are in contact, or that two adjacent seals 40 are spaced apart.

[0093] In the above embodiment, the locking member 2 can engage with the lock seat 300 in the first position, thereby locking the battery 100 and the lock seat 300. All the sealing members 40 seal the gap 50, which can achieve multi-layer sealing of the gap 50, thereby improving the sealing effect between the hole wall surface of the outlet hole 204 and the outer surface of the locking member 2, and reducing the risk of impurities entering the mounting cavity 203 and the sleeve 1 through the gap 50.

[0094] In some embodiments, please refer to Figures 5 and 7, where Figure 7 is a partial enlarged view of region A in Figure 5. A plurality of seals 40 include a first seal 401 and a second seal 402, spaced apart along the extending direction X of the outlet hole. The first seal 401 is closer to the mounting cavity 203 than the second seal 402. When the locking member 2 is in the second position, at least a portion of the first seal 401 is located within the outlet hole 204 to seal the gap 50, while the second seal 402 is located outside the outlet hole 204.

[0095] The plurality of seals 40 may also include a third seal 40, which may be spaced apart between the first seal 401, the second seal 402 and the third seal 40, or the third seal 40 may be connected to the first seal 401 and the second seal 402.

[0096] The first seal 401 may be entirely located inside the outlet hole 204, with the first seal 401 positioned between the hole wall of the outlet hole 204 and the outer surface of the locking member 2 to seal the gap 50; alternatively, a portion of the first seal 401 may be located inside the outlet hole 204, while another portion may be located outside the outlet hole 204, with the portion located inside the outlet hole 204 sealing the gap 50.

[0097] In the above embodiments, when the locking member 2 is in the first position, all the seals 40 can seal the gap 50, and when the locking member 2 is in the second position, the second seal 402 is located outside the outlet hole 204. During the process of the locking member 2 switching from the first position to the second position, the second seal 402 can also carry out some of the impurities at the outlet hole 204 to clean the impurities at the outlet hole 204 and reduce the risk of impurities entering the mounting cavity 203 and the sleeve 1.

[0098] In some embodiments, when the locking member 2 is in the second position, a portion of the first seal 401 is located outside the outlet hole 204.

[0099] As an example, as shown in Figure 7, the housing 20 has a first outer surface 206, one end of the outlet hole 204 is connected to the mounting cavity 203, the other end of the outlet hole 204 passes through the first outer surface 206, and a portion of the first seal 401 protrudes from the first outer surface 206.

[0100] In the above embodiment, when the locking member 2 is switched from the first position to the second position, a portion of the first sealing member 401 in the outlet hole 204 is moved out of the outlet hole 204 to draw out the impurities in the outlet hole 204, so as to facilitate cleaning the impurities at the gap 50 and reduce the risk of impurities entering the mounting cavity 203 and the sleeve 1.

[0101] In some embodiments, please refer to Figure 8, which is a partial enlarged view of region B in Figure 6. When the locking member 2 is in the first position, a portion of the second sealing member 402 is located outside the outlet hole 204, and another portion is located inside the outlet hole 204, to seal the gap 50.

[0102] As an example, as shown in Figure 8, a portion of the second seal 402 is located within the outlet hole 204 to seal the gap 50, and another portion of the second seal 402 protrudes from the first outer surface 206.

[0103] In the above embodiment, when the locking member 2 is in the first position, a portion of the second sealing member 402 is located outside the outlet hole 204. The second sealing member 402 can block impurities from entering the gap 50, thereby reducing the risk of impurities entering the mounting cavity 203 and the sleeve 1.

[0104] In some embodiments, please refer to FIG9, which is an exploded view of a sleeve 1 and a locking member 2 provided in some embodiments of this application. A guide structure 60 is provided between the sleeve 1 and the locking member 2. The guide structure 60 is configured to guide the locking member 2 to rotate about a first axis when it moves between a first position and a second position, so that the locking member 2 engages or disengages from the lock seat 300. The first axis is parallel to the extension direction X of the lead-out hole.

[0105] The guide structure 60 may include a first limiting part disposed on the sleeve 1 and a second limiting part disposed on the locking member 2. The first limiting part and the second limiting part cooperate to guide the locking member 2 to rotate around the first axis when it moves between the first position and the second position.

[0106] The locking element 2 can be a rod-shaped structure, and the first axis can be the center line of the rod-shaped structure.

[0107] By setting the guide structure 60 to guide the movement of the locking member 2, the movement of the locking member 2 is made more stable. The locking member 2 rotates to engage or disengage with the lock seat 300, making engagement more convenient.

[0108] In some embodiments, the guide structure 60 includes a limiting groove 601 disposed on the inner peripheral surface of the sleeve 1 and a protrusion 602 disposed on the outer peripheral surface of the locking member 2, at least a portion of the protrusion 602 being accommodated within the limiting groove 601.

[0109] There can be one or more protrusions 602. When there are multiple protrusions 602, each protrusion 602 can correspond one-to-one with the limiting groove 601, or multiple protrusions 602 can cooperate with the same limiting groove 601 to guide the locking member 2 to rotate around the first axis when it moves between the first position and the second position.

[0110] The limiting groove 601 can penetrate the outer circumferential surface of the sleeve 1 to facilitate the machining of the limiting groove 601. The limiting groove 601 can also be a groove only on the inner circumferential surface of the sleeve 1, and the limiting groove 601 is not directly connected to the external environment.

[0111] As an example, as shown in Figure 9, the inner circumferential surface of the sleeve 1 is provided with two limiting grooves 601, and the outer circumferential surface of the locking member 2 is provided with two protrusions 602. The two protrusions 602 are spaced apart along the outer circumference of the locking member 2, and a portion of the protrusions 602 is accommodated in the receiving groove. The protrusions 602 correspond one-to-one with the limiting grooves 601.

[0112] By setting a limiting groove 601 on the inner circumferential surface of the sleeve 1 and a protrusion 602 on the outer circumferential surface of the locking member 2, the locking member 2 is guided, making the processing of the guiding structure 60 more convenient.

[0113] In other embodiments, the guide structure 60 includes a protrusion 602 disposed on the inner peripheral surface of the sleeve 1 and a limiting groove 601 disposed on the outer peripheral surface of the locking member 2, with at least a portion of the protrusion 602 being accommodated within the limiting groove 601.

[0114] In some embodiments, the limiting groove 601 includes a first groove segment 6011, a second groove segment 6012, and a third groove segment 6013 connected in sequence. Both the first groove segment 6011 and the third groove segment 6013 extend along the extension direction X of the outlet hole. The first groove segment 6011 and the third groove segment 6013 are arranged at intervals along the circumference of the locking member 2, and are also arranged at intervals along the extension direction X of the outlet hole. Along the extension direction X of the outlet hole, the first groove segment 6011 penetrates one side of the telescopic member extending out of the sleeve 1. When the locking member 2 is in the first position, the protrusion 602 is located within the third groove segment 6013. When the locking member 2 is in the second position, the protrusion 602 is located within the first groove segment 6011.

[0115] The first groove segment 6011 and the third groove segment 6013 are arranged at intervals along the circumference of the locking member 2, and the first groove segment 6011 and the third groove segment 6013 are arranged at intervals along the extension direction X of the lead-out hole. That is, the first groove segment 6011 and the third groove segment 6013 of the limiting groove 601 are at a distance in the extension direction X of the lead-out hole, and are also at a distance in the circumference of the locking member 2. It should be noted that since the first groove segment 6011 and the third groove segment 6013 are arranged at intervals in the extension direction X of the outlet hole and in the circumferential direction of the locking member 2, the second groove segment 6012 connecting the first groove segment 6011 and the third groove segment 6013 is a spiral structure surrounding the locking member 2. When the protrusion 602 is located in the first groove segment 6011 and the third groove segment 6013, the locking member 2 can only move along the extension direction X of the outlet hole. However, when the protrusion 602 is located in the second groove segment 6012, the locking member 2 can move along the extension direction X of the outlet hole and rotate around the first axis.

[0116] When the locking member 2 is in the first position, the protrusion 602 is located in the third groove 6013. When the locking member 2 is in the second position, the protrusion 602 is located in the first groove 6011. That is to say, when the protrusion 602 of the locking member 2 moves from the first groove 6011 to the third groove 6013, the locking member 2 can move from the second position to the first position.

[0117] In the above embodiments, by setting the first groove segment 6011 and the third groove segment 6013 of the limiting groove 601 to extend along the extension direction X of the outlet hole, and the first groove segment 6011 and the third groove segment 6013 are evenly spaced in the extension direction X of the outlet hole and the circumferential direction of the locking member 2, the second groove segment 6012 is a spiral groove connecting the first groove segment 6011 and the third groove segment 6013. This allows the protrusion 602 of the locking member 2 to move along the first direction along the extension direction of the first groove segment 6011 and the second groove segment 6012 when it is located in the first groove segment 6011 and the third groove segment 6013. It also allows the protrusion 602 of the locking member 2 to rotate relative to the sleeve 1 and move relative to the sleeve 1 along the first direction when it is located in the second groove segment 6012. This achieves the limitation of the rotation angle of the locking member 2 and allows it to move between the first position and the second position along the extension direction X of the outlet hole.

[0118] In some embodiments, the battery 100 further includes an adjustment member 70, which is rotatably disposed on the sleeve 1 about a first axis and is threadedly connected to the locking member 2.

[0119] The adjustment member 70 can be rotated manually or driven by a drive mechanism; for example, the adjustment member 70 can be rotated by a motor. When the adjustment member 70 rotates relative to the sleeve 1, under the restriction of the limiting groove 601, the protrusion 602 can move along the limiting groove 601, so that the locking member 2 switches between the first position and the second position.

[0120] The adjusting component 70 drives the locking component 2 to move relative to the sleeve 1, thereby enabling the locking component 2 to switch between the first position and the second position, thus enabling the locking component 2 to engage or disengage from the lock seat 300.

[0121] In some embodiments, the limiting groove 601 extends to one end of the sleeve 1 near the outlet hole 204.

[0122] As an example, as shown in Figure 4, the sleeve 1 has a second surface 13 near the outlet hole 204, and two limiting grooves 601 penetrate the second surface 13. The locking member 2 is provided with two protrusions 602, which pass through the second surface 13 and enter the limiting grooves 601.

[0123] By setting a limiting groove 601 extending to one end of the sleeve 1 near the lead-out hole 204, it is convenient to insert the locking member 2 with the protrusion 602 into the sleeve 1, which facilitates the cooperation between the locking member 2 and the sleeve 1.

[0124] In the embodiment where the limiting groove 601 penetrates the second surface 13, the setting of the limiting groove 602 will cause impurities to enter the sleeve 1 through the limiting groove 602. However, the sleeve 1 and the locking member 2 cannot be sealed by setting the sealing member 40. Therefore, the risk of impurities entering the mounting cavity 203 can be reduced by setting the sealing member 40 between the hole wall of the outlet hole 204 and the outer surface of the locking member 2, thereby reducing the risk of impurities entering the sleeve 1 through the limiting groove 601.

[0125] In some embodiments, please continue to refer to Figures 5-8. The locking member 2 is provided with a first annular groove 21, which is arranged around the locking member 2 around a first axis. The sealing member 40 is sleeved on the locking member 2 and locked in the first annular groove 21. The first axis is parallel to the extension direction X of the outlet hole.

[0126] There can be one or more first annular grooves 21. When there are multiple seals 40, the seals 40 can correspond one-to-one with the first annular grooves 21, or multiple seals 40 can be engaged in the same first annular groove 21.

[0127] As an example, as shown in Figures 5-8, the locking member 2 is provided with two first annular grooves 21, and the first seal 401 and the second seal 402 are respectively locked in the two first annular grooves 21.

[0128] By providing a first annular groove 21 in the locking member 2, the seal 40 can be locked in the first annular groove 21, which is beneficial for the installation of the seal 40 and reduces the risk of the seal 40 falling off the first locking member 2.

[0129] In some embodiments, the sealing member 40 is sleeved on the locking member 2, and the outer peripheral surface of the sealing member 40 is provided with a second annular groove 403 surrounding the locking member 2.

[0130] On the same seal 40, there may be one or more second annular grooves 403. The second annular groove 403 is positioned opposite the wall surface of the outlet hole 204.

[0131] By providing a second annular groove 403, the contact area between the seal 40 and the hole wall of the outlet hole 204 can be reduced, thereby reducing the risk of damage to the seal 40 due to excessive friction between the seal 40 and the hole wall.

[0132] In some embodiments, there are multiple second annular grooves 403, and the multiple second annular grooves 403 are spaced apart along the extension direction X of the outlet hole.

[0133] As an example, as shown in Figure 8, the second seal 402 is disposed in the first annular groove 21. The second seal 402 has a second outer peripheral surface for abutting against the hole wall of the outlet hole 204. Two second annular grooves 403 are disposed on the second outer peripheral surface, and the two second annular grooves 403 are spaced apart along the extension direction X of the outlet hole.

[0134] Multiple second annular grooves 403 enable a single seal 40 to form a multi-stage seal at the gap 50, making the seal more stable.

[0135] In some embodiments, please continue to refer to Figure 9. The locking member 2 includes a locking rod 23 and a locking head 22. One end of the locking rod 23 is located inside the sleeve 1, and the locking head 22 is connected to the other end of the locking rod 23. The locking rod 23 passes through the outlet hole 204, and the locking head 22 is used to engage with the lock seat 300. The locking rod 23 is partially thickened to form a thickened section 232a. A gap 50 is formed between the outer peripheral surface of the thickened section 232a and the hole wall surface of the outlet hole 204. A sealing member 40 is disposed in the thickened section 232a.

[0136] The lock head 22 can be fixedly connected to the lock rod 23, for example, by welding the lock head 22 to the lock rod 23; or the lock head 22 can be detachably connected to the lock rod 23, for example, by having a threaded hole in the lock head 22 and screwing the lock head 22 to the lock rod 23.

[0137] The locking lever 23 may include a first lever portion 231, a second lever portion 232, and a third lever portion 233 connected in sequence. The first lever portion 231 is connected to the lock head 22, and the third lever portion 233 is connected to the adjusting member 70. The second lever portion 232 is a thickened section 232a. Along the extension direction X of the lead-out hole, the projections of the first lever portion 231 and the third lever portion 233 are both located within the second lever portion 232 and are smaller than the projection of the second lever portion 232, so that the diameter of the second lever portion 232 is larger than the diameter of the first lever portion 231 and the diameter of the third lever portion 233.

[0138] By setting the seal 40 in the thickened section 232a, the material used for the seal 40 can be reduced, the risk of damage to the seal 40 can be reduced, and the sealing performance of the seal 40 can be improved.

[0139] This application provides an electrical device including a lock base 300 and a battery 100 provided in any of the above embodiments. The locking member 2 is configured to engage or disengage from the lock base 300.

[0140] The electrical equipment can be any of the aforementioned devices or systems that use battery 100.

[0141] In some embodiments, the electrical device is a vehicle 1000, which includes a mounting bracket 200. The mounting bracket 200 is provided with a lock seat 300. A locking member 2 engages with the lock seat 300 to connect a battery 100 to the mounting bracket 200. The locking member 2 disengages from the lock seat 300 so that the battery 100 can be disconnected from the mounting bracket 200.

[0142] The lock base 300 and the mounting bracket 200 can be an integral structure or a separate structure. When the lock base 300 and the mounting bracket 200 are an integral structure, that is, the lock base 300 is part of the mounting bracket 200; when the lock base 300 and the mounting bracket 200 are separate structures, the lock base 300 can be connected to the mounting bracket 200 by welding, bolting, or snap-fitting. For example, in Figure 2, the lock base 300 and the mounting bracket 200 are separate structures, and the lock base 300 is bolted to the mounting bracket 200.

[0143] The battery 100 includes a locking mechanism 10, which is used to lock or unlock with the lock seat 300 to enable battery swapping of the vehicle 1000.

[0144] In some embodiments, referring to Figures 5 and 6, the lock seat 300 is provided with a lock hole 3001 for inserting the locking member 2. The lock hole 3001 extends through both sides of the lock seat 300 along the extending direction X of the outlet hole. After the locking member 2 is inserted into the lock hole 3001, the locking head 22 of the locking member 2 can be rotated about the axis extending along the extending direction X of the outlet hole by rotating the adjusting member 70. This allows the locking head 22 to engage with the surface of the lock seat 300 on the side away from the sleeve 1, so that the locking mechanism 10 and the lock seat 300 can be engaged. The locking mechanism 10 and the lock seat 300 are engaged in the extension direction X of the outlet hole, thereby achieving mutual locking between the locking mechanism 10 and the lock seat 300. Conversely, when the adjusting member 70 is rotated and the locking head 22 of the locking member 2 is rotated until the projection of the locking head 22 in the extension direction X of the outlet hole is located in the lock hole 3001, the locking member 2 can be disengaged from the lock hole 3001, so that the locking mechanism 10 and the lock seat 300 can be disengaged in the extension direction X of the outlet hole, thereby achieving mutual unlocking between the locking mechanism 10 and the lock seat 300.

[0145] The keyhole 3001 has a rectangular cross-section. When the extension direction of the lock head 22 is consistent with the length direction of the cross-section of the keyhole 3001, the lock head 22 can be inserted into the keyhole 3001 or can be withdrawn from the keyhole 3001. When the lock head 22 passes through the keyhole 3001 and the extension direction of the lock head 22 intersects with the length direction of the cross-section of the keyhole 3001, the lock head 22 can engage with the surface of the lock seat 300 on the side away from the sleeve 1.

[0146] Referring to Figures 4 to 9, this embodiment of the application provides a battery 100, including a battery cell 30, a housing 20, a locking mechanism 10, and a sealing member 40. The housing 20 is provided with a mounting cavity 203 and a lead-out hole 204, the lead-out hole 204 communicating with the mounting cavity 203. The locking mechanism 10 includes a sleeve 1 and a locking member 2. The sleeve 1 is fixed within the mounting cavity 203, and the sleeve 1 is fitted onto the locking member 2. The locking member 2 partially extends out of the sleeve 1 and passes through the lead-out hole 204. The locking member 2 has a first position engaging with the lock seat 300 of the vehicle 1000 and a second position disengaging from the lock seat 300 of the vehicle 1000. The sealing member 40 includes a first sealing member 401 and a second sealing member 402 spaced apart along the extension direction X of the lead-out hole. The first sealing member 401 is closer to the sleeve 1 than the second sealing member 402. When the locking member 2 is in the first position, both the first seal 401 and the second seal 402 seal the gap 50 between the hole wall of the outlet hole 204 and the outer surface of the locking member 2, and a portion of the second seal 402 is located outside the outlet hole 204; when the locking member 2 is in the second position, the first seal 401 seals the gap 50, the second seal 402 is located outside the outlet hole 204, and a portion of the first seal 401 is located outside the outlet hole 204.

[0147] By fixing the sleeve 1 inside the mounting cavity 203, and with the mounting cavity 203 communicating with the outlet hole 204, the sleeve 1 can communicate with the outside through the outlet hole 204. Since the locking member 2 extends out of the sleeve 1 and through the outlet hole 204, impurities from the external environment can easily enter the mounting cavity 203 and the sleeve 1 through the gap 50 between the hole wall of the outlet hole 204 and the outer surface of the locking member 2, easily clogging the sleeve 1 and causing the locking mechanism 10 to fail. By sealing the gap 50 with the sealing member 40, the amount of impurities entering the mounting cavity 203 and the sleeve 1 through the gap 50 can be reduced, thereby reducing the impact of impurities on the engagement or disengagement of the locking member 2 and the lock seat 300, thus reducing the risk of locking mechanism 10 failure and facilitating the disassembly and assembly between the battery 100 and the vehicle 1000.

[0148] 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.
