Along the second direction, a first accommodating gap is formed between two adjacent first fixing portions, and the first accommodating gap is used to accommodate at least one second fixing portion of another battery.

[0013] In some embodiments, along the second direction, the first fixing portions and the second fixing portions are alternately arranged in sequence.

[0014] In the above technical solution, by setting the first fixing part and the second fixing part on the battery box to a structure that is arranged alternately in sequence along the second direction, the first accommodating gap of one battery is only used to accommodate one second fixing part of another battery. On the one hand, the battery with this structure facilitates the arrangement of multiple batteries along the first direction, which is beneficial to reduce the difficulty of battery assembly. On the other hand, it can improve the balance of the distribution of the first fixing part and the second fixing part of the battery, so as to improve the stability and stability of the battery being locked on the target part through the locking mechanism.

[0015] In some embodiments, along the first direction, a dimension of the first fixing portion protruding from the first surface is equal to a dimension of the second fixing portion protruding from the second surface.

[0016] In the above technical solution, by setting the size of the first fixing portion protruding from the first surface to be equal to the size of the second fixing portion protruding from the second surface, the first fixing portion and the second fixing portion can avoid each other when multiple batteries are arranged along the first direction, and the mutual interference between the first fixing portion and the second fixing portion can be reduced, which is conducive to alleviating the phenomenon that the gap between the second fixing portion and the first surface is too large or the gap between the first fixing portion and the second surface is too large due to the size of the first fixing portion protruding from the first surface being too large or the size of the second fixing portion protruding from the second surface being too large, thereby further reducing the gap between multiple batteries and further improving the space utilization of the batteries.

[0017] In some embodiments, the first fixing portion is in the shape of a cuboid; and / or the second fixing portion is in the shape of a cuboid.

[0018] In the above technical solution, by setting the first fixing portion as a rectangular parallelepiped structure, the first fixing portion with such a structure is easy to manufacture and process, which helps to reduce the difficulty of setting the first fixing portion on the first surface. On the other hand, it can improve the regularity of the shape of the first fixing portion, thereby reducing the difficulty of the first fixing portion avoiding the second fixing portion and facilitating the arrangement of multiple batteries along the first direction. Similarly, by setting the second fixing portion as a rectangular parallelepiped structure, the second fixing portion with such a structure is easy to manufacture and process, which helps to reduce the difficulty of setting the second fixing portion on the second surface. On the other hand, it can improve the regularity of the shape of the second fixing portion, thereby reducing the difficulty of the second fixing portion avoiding the first fixing portion and facilitating the arrangement of multiple batteries along the first direction.

[0019] In some embodiments, the box body includes a box body and a box cover; the interior of the box body forms a accommodating space with an opening, and the accommodating space is used to accommodate battery cells; the box cover covers the opening; wherein, along the first direction, the two sides of the box body respectively form a first surface and a second surface.

[0020] In the above technical solution, the box body is provided with a box body and a box cover, the box body is used to accommodate battery cells, and the box cover is closed at the opening of the box body to realize the assembly and accommodation of the battery cells, and the box body forms a first surface and a second surface on both sides in the first direction, respectively, so that the first fixing part and the second fixing part are structures arranged on the box body. Since the box body is used to accommodate battery cells, the box body is the main load-bearing component of the box body. Therefore, by arranging the first fixing part and the second fixing part on the box body, the locking mechanism can directly support the box body, which is beneficial to improve the box body's load-bearing capacity for battery cells and can alleviate the phenomenon of excessive force between the box cover and the box body.

[0021] In a second aspect, an embodiment of the present application further provides an electrical device comprising a plurality of the above-mentioned batteries, wherein the plurality of batteries are arranged along a first direction; wherein, in two adjacent batteries, the first surface of one battery and the second surface of the other battery are arranged facing each other, and the first fixing portion of one battery and the second fixing portion of the other battery are arranged along a second direction, and the second direction is perpendicular to the first direction.

[0022] In the above technical solution, the electrical device is provided with a plurality of batteries, and the plurality of batteries are arranged along a first direction, and in two adjacent batteries, the first fixing portion of one battery and the second fixing portion of the other battery are structures arranged along a second direction, so that the first fixing portion of one battery is located on one side of the second fixing portion of the other battery in the second direction, so that the first fixing portion and the second fixing portion of the two adjacent batteries can avoid each other, thereby enabling the plurality of batteries to share part of the space in the first direction, so as to reduce the overall size of the plurality of batteries arranged along the first direction, thereby saving the space occupied by the plurality of batteries on the electrical device, and helping to improve the space utilization rate of the plurality of batteries.

[0023] In some embodiments, along the first direction, in two adjacent batteries, the distance between the first surface and the second surface is L1, the dimension of the first fixing portion protruding from the first surface is L2, and the dimension of the second fixing portion protruding from the second surface is L3, satisfying 1.1L2≤L1≤1.6L2, 1.1L3≤L1≤1.6L3.

[0024] In the above technical solution, in two adjacent batteries, by setting the distance between the first surface of one battery and the second surface of the other battery to be greater than or equal to 1.1 times the size of the first fixing portion protruding on the first surface, the phenomenon of the assembly space between the first surface of one battery and the second surface of the other battery being too small is alleviated, thereby reducing the interference and scratching between the first fixing portion of one battery and the second surface of the other battery, which is beneficial to reducing the difficulty of assembling multiple batteries in sequence along the first direction, and by setting the distance between the first surface of one battery and the second surface of the other battery to be less than or equal to 1.6 times the size of the first fixing portion protruding on the first surface, the phenomenon of the reserved assembly gap between the first surface of one battery and the second surface of the other battery being too large is alleviated, thereby saving the space occupied by multiple batteries in the first direction, which is beneficial to further improve the space utilization of the batteries. Similarly, by setting the distance between the first surface of a battery and the second surface of another battery to be greater than or equal to 1.1 times the size of the second fixing portion protruding on the second surface, the phenomenon of the assembly space between the first surface of a battery and the second surface of another battery being too small can be alleviated, thereby reducing the interference and scratching between the second fixing portion of one battery and the first surface of another battery, which is beneficial to reducing the difficulty of assembling multiple batteries in sequence along the first direction, and by setting the distance between the first surface of a battery and the second surface of another battery to be less than or equal to 1.6 times the size of the second fixing portion protruding on the second surface, the phenomenon of the reserved assembly gap between the first surface of a battery and the second surface of another battery being too large can be alleviated, thereby saving the space occupied by multiple batteries in the first direction, which is beneficial to further improve the space utilization of the batteries.

[0025] In some embodiments, the electrical device also includes a target part and a locking mechanism; the locking mechanism is arranged on two adjacent batteries, along a first direction, in the two adjacent batteries, the locking mechanism connects the first fixing part of one battery and the second fixing part of the other battery, and the locking mechanism is used to engage or disengage with the target part along a third direction to lock or unlock the box and the target part, and the third direction is perpendicular to the first direction and the second direction.

[0026] In the above technical solution, the locking mechanism of the electrical device is a first fixing part connecting one of the two adjacent batteries and a second fixing part of the other battery, so that the first fixing part and the second fixing part of the two adjacent batteries share a locking mechanism, and are locked to the target part through a locking mechanism. The electrical device adopting this structure can simultaneously realize the locking or unlocking of the two adjacent batteries, and can first assemble the two adjacent batteries and the locking mechanism into a whole and then lock them with the target part to realize the battery replacement of multiple batteries. On the one hand, it can further optimize and reduce the assembly space reserved between multiple batteries to further increase the tightness of the mutual assembly between multiple batteries, which is beneficial to improving the space utilization of the batteries. On the other hand, the locking or unlocking of the two adjacent batteries is realized through a locking mechanism, so there is no need to lock or unlock the corresponding multiple batteries multiple times, so that the locking action or unlocking action required for multiple batteries during the battery replacement process is reduced, which is beneficial to optimizing the battery replacement rhythm of multiple batteries, thereby improving the battery replacement efficiency and saving the battery replacement cost.

[0027] In some embodiments, the locking mechanism includes a locking sleeve, an adjusting member and two locking members; along the first direction, in two adjacent batteries, the locking sleeve connects the first fixing portion of one battery and the second fixing portion of the other battery; along the first direction, in two adjacent batteries, the two locking members are respectively inserted into the first fixing portion of one battery and the second fixing portion of the other battery, and the two locking members are movably provided in the locking sleeve, and the locking members have a locked state and an unlocked state, and the locking members are configured to engage with the target member when in the locked state so that the locking mechanism and the target member engage along a third direction, and the locking member is configured to disengage from the target member when in the unlocked state so as to allow the locking mechanism and the target member to disengage along the third direction; the adjusting member is provided in the locking sleeve, and the adjusting member is configured to drive the two locking members to move relative to the locking sleeve so that the locking members switch between the locked state and the unlocked state.

[0028] In the above technical solution, the locking mechanism is provided with a locking sleeve, an adjusting member and two locking members. By connecting the locking sleeve to the first fixing part of one battery and the second fixing part of the other battery in two adjacent batteries, the first fixing part and the second fixing part of the two adjacent batteries can share a locking mechanism and be connected to each other as a whole for battery replacement. In addition, the two locking members are respectively inserted into the first fixing part of one battery and the second fixing part of the other battery, and the adjusting member can drive the two locking members to switch between a locked state and an unlocked state, so that the first fixing part of one battery and the second fixing part of the other battery in the two adjacent batteries are both locked with the target part, so that while improving the stability of the mutual locking between the battery and the target part, the two locking members can also be moved between unlocking and locking through an adjusting member, which is conducive to further reducing the locking or unlocking actions required for multiple batteries during the battery replacement process, and can further improve the operating efficiency of the locking mechanism and the battery replacement efficiency.

It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of this application, as well as the overall thickness, length, width, and other dimensions of the integrated device shown in the drawings are merely illustrative and should not constitute any limitation on this application.

[0049] The term "plurality" used in this application refers to two or more (including two).

[0050] In the embodiment of the present application, the battery cell may be a secondary battery. A secondary battery refers to a battery cell that can be continuously used by activating active materials by charging after the battery cell is discharged.

[0051] The battery cells can be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-hydrogen batteries, nickel-cadmium batteries, lead-acid batteries, etc., which are not limited in the embodiments of the present application.

[0052] A battery cell typically includes an electrode assembly. This assembly includes a positive electrode, a negative electrode, and a separator. During the charge and discharge process of a battery cell, active ions (such as lithium ions) are inserted and removed between the positive and negative electrodes. The separator, placed between the positive and negative electrodes, prevents short circuits between the positive and negative electrodes while allowing the active ions to pass through.

[0053] In some embodiments, the positive electrode may be a positive electrode sheet, and the negative electrode may be a negative electrode sheet.

[0054] In some embodiments, the electrode assembly further includes a separator disposed between the positive electrode and the negative electrode.

[0055] In some embodiments, the separator is a separator.

[0056] In some embodiments, a battery cell may include a housing. The housing is used to encapsulate components such as the electrode assembly and the electrolyte. The housing may be a steel housing, an aluminum housing, a plastic housing (e.g., polypropylene), a composite metal housing (e.g., a copper-aluminum composite housing), or an aluminum-plastic film.

[0057] As an example, the battery cells may be cylindrical battery cells, prismatic battery cells, soft-pack battery cells or battery cells of other shapes. Prismatic battery cells include but are not limited to square-shell battery cells, blade-shaped battery cells, and polygonal prismatic batteries, such as hexagonal prismatic batteries.

[0058] The battery mentioned in the embodiments of the present application refers to a single physical module including one or more battery cells to provide higher voltage and capacity.

[0059] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0060] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0061] With technological advancements and the rapid development of new energy vehicles, electric vehicles are gaining increasing market share and increasing in frequency of use. Electric commercial vehicles, such as heavy-duty and light-duty electric trucks, are gradually appearing in various application scenarios, and battery swap stations have been built to accommodate these vehicles.

[0062] In the field of new energy vehicles, electric trucks consume more energy than ordinary passenger cars due to their heavy loads and long driving range. Therefore, to achieve endurance, electric trucks are usually equipped with multiple batteries and require frequent battery swaps. During the battery swap process, the locking and separation of the battery on the vehicle are key issues. To achieve this, the main method currently used is to install a lock seat on the vehicle and a corresponding locking mechanism on the battery. The locking mechanism and the lock seat are used to lock or unlock the battery to complete the vehicle's battery swap function. However, since the multiple batteries are independent individuals and the multiple batteries are arranged in sequence on the vehicle, multiple locking mechanisms need to be set for each battery for locking, and in the arrangement direction of the multiple batteries, the fixing points on both sides of the battery for assembling and fixing the locking mechanisms are symmetrically arranged, so that when the multiple batteries are arranged, the fixing points between two adjacent batteries are arranged in sequence along the arrangement direction of the multiple batteries, and each locking mechanism needs to reserve corresponding operating space, which leads to poor assembly tightness between the multiple batteries, so that the multiple batteries occupy more space on the vehicle, which is not conducive to improving the space utilization of the batteries on the vehicle.

[0063] Based on the above considerations, and to address the issue of low battery space utilization, embodiments of the present application provide a battery comprising a housing for accommodating battery cells. The housing has a first surface and a second surface formed on either side thereof in a first direction, a first fixing portion projecting from the first surface, and a second fixing portion projecting from the second surface. The first fixing portion and the second fixing portion are both used to mount a locking mechanism, which is used to lock the housing to a target component. Along the first direction, the projection of the first fixing portion and the projection of the second fixing portion do not overlap.

[0064] In a battery of this structure, a first surface and a second surface are formed on both sides of the battery case in the first direction, and the first surface is convexly provided with a first fixing portion for locking with the target part through a locking mechanism, and the second surface is convexly provided with a second fixing portion for locking with the target part through the locking mechanism, so that after the first fixing portion and the second fixing portion are locked with the target part through the locking mechanism, the battery can be assembled to the target part, thereby improving the stability of the battery assembled to the target part, wherein, by setting the projection of the first fixing portion in the first direction and the projection of the second fixing portion in the first direction to a non-overlapping structure, so that the first fixing portion and the second fixing portion are staggered in the first direction, when multiple batteries are arranged along the first direction, the first fixing portion and the second fixing portion can avoid each other and share part of the space in the first direction, and there is no need to set the first fixing portion of one battery and the second fixing portion of another battery to be arranged in sequence along the first direction, so that multiple batteries can share part of the space in the first direction, thereby effectively reducing the overall size of the multiple batteries arranged in the first direction, saving the space occupied by the multiple batteries in the first direction, which is beneficial to improving the space utilization of the batteries.

[0065] The batteries disclosed in the embodiments of this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. A power supply system comprising the batteries disclosed in this application can be used to construct such electrical devices, thereby alleviating the problem of low battery assembly density in vehicles and improving battery space utilization.

[0066] The present invention provides an electric device that uses a battery as a power source. The electric device may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, etc. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc. The spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

The multiple battery cells 20 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by the multiple battery cells 20 may be accommodated in the housing 10. Of course, the battery 100 may also be a battery module formed by first connecting multiple battery cells 20 in series, in parallel, or in a mixed connection, and then the multiple battery modules may be connected in series, in parallel, or in a mixed connection to form a whole, and then accommodated in the housing 10. In some embodiments, the battery 100 may also include other structures. For example, the battery 100 may also include a busbar component, which is used to connect the multiple battery cells 20 to achieve electrical connection between the multiple battery cells 20.

[0074] Each battery cell 20 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 can be cylindrical, flat, rectangular, or in other shapes. For example, in FIG6 , the battery cell 20 is a rectangular parallelepiped.

[0075] According to some embodiments of the present application, with reference to Figures 3, 4, 5, and 6, and further with reference to Figure 7, which is a top view of a battery 100 provided in some embodiments of the present application. The present application provides a battery 100, comprising a housing 10 for accommodating a battery cell 20. The housing 10 has a first surface 111 and a second surface 112 formed on either side in a first direction X, respectively. A first fixing portion 113 is protruding from the first surface 111, and a second fixing portion 114 is protruding from the second surface 112. Both the first fixing portion 113 and the second fixing portion 114 are used to mount a locking mechanism 400, which is used to lock the housing 10 to a target object. Along the first direction X, the projection of the first fixing portion 113 and the projection of the second fixing portion 114 do not overlap.

[0076] The box body 10 is used to accommodate the battery cells 20 , that is, the box body 10 serves to provide an assembly space for the battery cells 20 . The structure of the box body 10 can be various.

[0077] In some embodiments, as shown in FIG6 , the box body 10 may include a box body 11 and a box cover 12 . The box body 11 and the box cover 12 cover each other, and together define an assembly space for accommodating the battery cells 20. The box body 11 and the box cover 12 may each be a hollow structure with one side open, and the open side of the box cover 12 covers the open side of the box body 11, so that the box body 11 and the box cover 12 together define the assembly space.

[0078] Of course, the structure of the box body 10 is not limited to this. The box body 10 can also have other structures. For example, the box body 11 can be a hollow structure with one side open, and the box cover 12 can be a plate-like structure. The box cover 12 covers the open side of the box body 11, so that the box cover 12 and the box body 11 together define an assembly space. Similarly, the box body 10 formed by the box body 11 and the box cover 12 can also have various shapes, such as a cylinder, a rectangular parallelepiped, etc. For example, in Figures 5 and 6, the box body 11 is in the shape of a rectangular parallelepiped.

[0079] The box body 10 has a first surface 111 and a second surface 112 formed on both sides of the first direction X, that is, the two surfaces of the box body 10 on both sides of the first direction X are the first surface 111 and the second surface 112 respectively. In other words, the box body 10 has a first surface 111 and a second surface 112 arranged opposite to each other in the first direction X.

[0080] The first surface 111 is provided with a first fixing portion 113, and the second surface 112 is provided with a second fixing portion 114, that is, the first fixing portion 113 and the second fixing portion 114 are respectively provided on the surfaces of both sides of the box body 10 in the first direction X. For example, in Figures 5 and 6, the first fixing portion 113 and the second fixing portion 114 are both provided on the box body 11 of the box body 10, that is, the box body 11 forms a first surface 111 and a second surface 112 on both sides in the first direction X, wherein the first fixing portion 113 and the second fixing portion 114 are respectively provided on the box body 11 of the box body 10. 14 are used to install the locking mechanism 400, that is, in the embodiment where the box body 10 includes the box body 11 and the box cover 12, the locking mechanism 400 can be installed on the box body 11. Of course, in other embodiments, the first fixing portion 113 and the second fixing portion 114 are both arranged on the box cover 12 of the box body 10, that is, the box cover 12 forms a first surface 111 and a second surface 112 on both sides in the first direction X, that is, in the embodiment where the box body 10 includes the box body 11 and the box cover 12, the locking mechanism 400 can also be installed on the box cover 12.

[0081] The first fixing portion 113 and the second fixing portion 114 are both used to install the locking mechanism 400, and the locking mechanism 400 is used to lock the box body 10 to the target part, that is, the first fixing portion 113 and the second fixing portion 114 of the box body 10 can be locked to the target part through the locking mechanism 400. For example, in Figure 2, the locking mechanism 400 is used to lock or unlock with the lock seat 300 on the mounting frame 200 of the vehicle 1000, that is, the target part is the lock seat 300 provided on the mounting frame 200 of the vehicle 1000, and the first fixing portion 113 and the second fixing portion 114 of the box body 10 can be fastened to the lock seat 300 of the vehicle 1000 through the locking mechanism 400 to realize the battery replacement function of the battery 100 of the vehicle 1000.

[0082] Along the first direction X, the projection of the first fixing portion 113 and the projection of the second fixing portion 114 do not overlap, that is, the first fixing portion 113 and the second fixing portion 114 are arranged in a staggered manner in the first direction X. In other words, along the first direction X, the orthographic projection of the first fixing portion 113 on the first surface 111 and the orthographic projection of the second fixing portion 114 on the first surface 111 do not contact each other. For example, as shown in FIG. 4 , when multiple batteries 100 are arranged along the first direction X, the first fixing portion 113 of one battery 100 can avoid the second fixing portion 114 of another battery 100, so that the first fixing portion 113 and the second fixing portion 114 between two adjacent batteries 100 can be arranged along the second direction Y, which is perpendicular to the first direction X.

[0083] 3 and 4 , the surfaces on both sides of the first fixing portion 113 in the third direction Z are respectively flush with the surfaces on both sides of the second fixing portion 114 in the third direction Z, so that the upper surface of the first fixing portion 113 in the third direction Z and the upper surface of the second fixing portion 114 in the third direction Z are coplanar, and the lower surface of the first fixing portion 113 in the third direction Z and the lower surface of the second fixing portion 114 in the third direction Z are coplanar, so that the first fixing portion 113 and the second fixing portion 114 are located at the same height position in the third direction Z. For example, in FIG5 and FIG6 , the first direction X, the second direction Y and the third direction Z are perpendicular to each other, the first direction X is the width direction of the battery 100, the second direction Y is the length direction of the battery 100, and the third direction Z is the height direction of the battery 100, and the box body 11 and the box cover 12 are structures that cover each other along the third direction Z.

[0084] In this embodiment, the box body 10 of the battery 100 is respectively formed with a first surface 111 and a second surface 112 on both sides in the first direction X, and the first surface 111 is convexly provided with a first fixing portion 113 for locking with the target part through the locking mechanism 400, and the second surface 112 is convexly provided with a second fixing portion 114 for locking with the target part through the locking mechanism 400, so that the battery 100 can be assembled to the target part after the first fixing portion 113 and the second fixing portion 114 are locked with the target part through the locking mechanism 400, thereby improving the stability of the battery 100 assembled to the target part, wherein, by setting the projection of the first fixing portion 113 in the first direction X and the projection of the second fixing portion 114 in the first direction X to not overlap each other The structure is such that the first fixing portion 113 and the second fixing portion 114 are staggered in the first direction X. Thus, when the multiple batteries 100 are arranged along the first direction X, the first fixing portion 113 and the second fixing portion 114 can avoid each other and share part of the space in the first direction X. There is no need to set the first fixing portion 113 of one battery 100 and the second fixing portion 114 of another battery 100 to be arranged in sequence along the first direction X, so that the multiple batteries 100 can share part of the space in the first direction X, thereby effectively reducing the overall size of the multiple batteries 100 arranged along the first direction X, saving the space occupied by the multiple batteries 100 in the first direction X, and facilitating improved space utilization of the batteries 100.

[0085] According to some embodiments of the present application, referring to Figures 4, 5 and 6, a plurality of first fixing portions 113 are protruding from the first surface 111, and the plurality of first fixing portions 113 are arranged at intervals along the second direction Y. Along the second direction Y, a first accommodating gap 115 is formed between two adjacent first fixing portions 113. The first accommodating gap 115 is used to accommodate at least one second fixing portion 114 of another battery 100. The second direction Y is perpendicular to the first direction X.

[0086] Among them, the first accommodating gap 115 is used to accommodate at least one second fixing portion 114 of another battery 100, that is, between each two adjacent first fixing portions 113 in the second direction Y, at least one second fixing portion 114 of another battery 100 can be inserted along the first direction X, so that a first accommodating gap 115 for accommodating the second fixing portion 114 of another battery 100 is formed between the two adjacent first fixing portions 113.

[0087] For example, in FIG4 , each first accommodating gap 115 is for inserting a second fixing portion 114 of another battery 100 . Of course, in other embodiments, each first accommodating gap 115 may also be for inserting two, three or four second fixing portions 114 of another battery 100 .

[0088] In this embodiment, a plurality of first fixing portions 113 are provided on the first surface 111 of the case 10. The plurality of first fixing portions 113 are arranged along the second direction Y, and a first accommodating gap 115 for accommodating the second fixing portion 114 of another battery 100 is formed between two adjacent first fixing portions 113. This allows the second fixing portion 114 of one battery 100 to be inserted into the first accommodating gap 115 of another battery 100 when the plurality of batteries 100 are arranged along the first direction X. This saves the space occupied by the plurality of batteries 100 in the first direction X, and at the same time increases the number of first fixing portions 113 on the case 10 for installing the locking mechanism 400, thereby improving the firmness with which the battery 100 is locked to the target component, thereby achieving both improved space utilization of the battery 100 and improved stability and reliability of the battery 100 when assembled to the target component.

[0089] According to some embodiments of the present application, please continue to refer to Figures 4, 5 and 6. The second surface 112 is protruding with a plurality of second fixing portions 114, and the plurality of second fixing portions 114 are arranged at intervals along the second direction Y. Along the second direction Y, a second accommodating gap 116 is formed between two adjacent second fixing portions 114. The second accommodating gap 116 is used to accommodate at least one first fixing portion 113 of another battery 100.

[0090] Among them, the second accommodating gap 116 is used to accommodate at least one first fixing portion 113 of another battery 100, that is, between each two adjacent second fixing portions 114 in the second direction Y, at least one first fixing portion 113 of another battery 100 can be inserted along the first direction X, so that a second accommodating gap 116 for accommodating the first fixing portion 113 of another battery 100 is formed between the two adjacent second fixing portions 114.

[0091] For example, in FIG4 , each second accommodating gap 116 is for inserting a first fixing portion 113 of another battery 100 . Of course, in other embodiments, each second accommodating gap 116 may also be for inserting two, three or four first fixing portions 113 of another battery 100 .

[0092] In this embodiment, a plurality of second fixing portions 114 are provided on the second surface 112 of the case 10. The plurality of second fixing portions 114 are arranged along the second direction Y, and a second accommodating gap 116 for accommodating the first fixing portion 113 of another battery 100 is formed between two adjacent second fixing portions 114. This allows the first fixing portion 113 of one battery 100 to be inserted into the second accommodating gap 116 of another battery 100 when the plurality of batteries 100 are arranged along the first direction X. This saves the space occupied by the plurality of batteries 100 in the first direction X, and further increases the number of second fixing portions 114 on the case 10 for installing the locking mechanism 400, thereby further improving the firmness with which the battery 100 is locked to the target component. This not only improves the space utilization of the battery 100, but also further improves the stability and reliability of the battery 100 when assembled to the target component.

[0093] In some embodiments, as shown in Figures 3, 4, and 7, the first fixing portions 113 and the second fixing portions 114 are alternately arranged along the second direction Y. That is, after the multiple batteries 100 are arranged along the first direction X and the second fixing portions 114 are inserted into the first receiving gaps 115, the first fixing portions 113 of one battery 100 and the second fixing portions 114 of another battery 100 are alternately arranged along the second direction Y.

[0094] Among them, in an embodiment in which there are multiple first fixing portions 113 and multiple second fixing portions 114, correspondingly, only one second fixing portion 114 is accommodated in the first accommodating gap 115 between each two adjacent first fixing portions 113 in the second direction Y, and conversely, only one first fixing portion 113 is accommodated in the second accommodating gap 116 between each two adjacent second fixing portions 114 in the second direction Y.

[0095] In this embodiment, by setting the first fixing portion 113 and the second fixing portion 114 on the box body 10 of the battery 100 to a structure that is arranged alternately in sequence along the second direction Y, the first accommodating gap 115 of one battery 100 is only used to accommodate one second fixing portion 114 of another battery 100. The battery 100 with such a structure, on the one hand, facilitates the arrangement of multiple batteries 100 along the first direction X, which is conducive to reducing the difficulty of assembling the battery 100; on the other hand, it can improve the distribution balance of the first fixing portion 113 and the second fixing portion 114 of the battery 100, thereby improving the stability and stability of the battery 100 locked on the target part through the locking mechanism 400.

[0096] According to some embodiments of the present application, as shown in FIG7 , along the first direction X, the dimension of the first fixing portion 113 protruding from the first surface 111 is equal to the dimension of the second fixing portion 114 protruding from the second surface 112. In other words, the thickness of the first fixing portion 113 in the first direction X is equal to the thickness of the second fixing portion 114 in the first direction X.

[0097] In this embodiment, by setting the size of the first fixing portion 113 protruding from the first surface 111 to be equal to the size of the second fixing portion 114 protruding from the second surface 112, the first fixing portion 113 and the second fixing portion 114 can avoid each other when the multiple batteries 100 are arranged along the first direction X, and the mutual interference between the first fixing portion 113 and the second fixing portion 114 can be reduced, which is conducive to alleviating the phenomenon that the gap between the second fixing portion 114 and the first surface 111 is too large or the gap between the first fixing portion 113 and the second surface 112 is too large due to the first fixing portion 113 protruding from the first surface 111 or the second fixing portion 114 protruding from the second surface 112 is too large, thereby further reducing the gap between the multiple batteries 100, thereby further improving the space utilization of the battery 100.

[0098] In some embodiments, as shown in Figures 4 and 7 , the first fixing portion 113 is in the shape of a cuboid. Of course, in other embodiments, the shape of the first fixing portion 113 may also be cylindrical or polygonal.

[0099] In this embodiment, by setting the first fixing portion 113 as a rectangular parallelepiped structure, the first fixing portion 113 with such a structure is easy to manufacture and process, which is conducive to reducing the difficulty of setting the first fixing portion 113 on the first surface 111. On the other hand, it can improve the regularity of the shape of the first fixing portion 113, thereby reducing the difficulty of the first fixing portion 113 avoiding the second fixing portion 114, and facilitating the arrangement of multiple batteries 100 along the first direction X.

[0100] In some embodiments, as shown in Figures 5 and 7 , the second fixing portion 114 is in the shape of a cuboid. Of course, in other embodiments, the second fixing portion 114 may also be in the shape of a cylinder or a polygonal column.

[0101] In this embodiment, by setting the second fixing portion 114 as a rectangular parallelepiped structure, the second fixing portion 114 with such a structure is easy to manufacture and process, which is conducive to reducing the difficulty of setting the second fixing portion 114 on the second surface 112. On the other hand, it can improve the regularity of the shape of the second fixing portion 114, thereby reducing the difficulty of the second fixing portion 114 avoiding the first fixing portion 113, and facilitating the arrangement of multiple batteries 100 along the first direction X.

[0102] According to some embodiments of the present application, as shown in Figures 5 and 6 , a box body 10 may include a box body 11 and a box cover 12. The box body 11 defines an interior housing having an opening 117 for accommodating a battery cell 20. The box cover 12 covers the opening 117. Along a first direction X, the box body 11 defines a first surface 111 and a second surface 112 on either side thereof.

[0103] In the first direction X, the box body 11 has two sides forming a first surface 111 and a second surface 112 , respectively. That is, the first fixing portion 113 and the second fixing portion 114 are respectively protruded from the surfaces of the box body 11 on both sides in the first direction X.

[0104] In this embodiment, the box body 10 is provided with a box body 11 and a box cover 12. The box body 11 is used to accommodate the battery cell 20. The box cover 12 covers the opening 117 of the box body 11 to assemble and accommodate the battery cell 20, and the box body 11 forms a first surface 111 and a second surface 112 on both sides in the first direction X, respectively, so that the first fixing portion 113 and the second fixing portion 114 are structures arranged on the box body 11. Since the box body 11 is used to accommodate the battery cell 20, the box body 11 is the main load-bearing component of the box body 10. Therefore, by arranging the first fixing portion 113 and the second fixing portion 114 on the box body 11, the locking mechanism 400 can directly support the box body 11, which is beneficial to improving the load-bearing capacity of the box body 10 for the battery cell 20 and can alleviate the phenomenon of excessive force between the box cover 12 and the box body 11.

[0105] According to some embodiments of the present application, the present application further provides an electrical device, comprising the battery 100 of any of the above solutions.

[0106] The power-consuming device may be any of the aforementioned devices or systems using the battery 100 .

[0107] For ease of explanation, the following embodiments are described using a vehicle 1000 as an example of an electrical device according to one embodiment of the present application. Referring to Figures 1, 2, 3, 4, and 7, multiple batteries 100 are arranged along a first direction X. In two adjacent batteries 100, the first surface 111 of one battery 100 faces the second surface 112 of the other battery 100, and the first fixing portion 113 of one battery 100 faces the second fixing portion 114 of the other battery 100. The second direction Y is perpendicular to the first direction X.

[0108] Among them, in two adjacent batteries 100, the first surface 111 of one battery 100 is arranged facing the second surface 112 of the other battery 100, that is, the multiple batteries 100 are arranged in sequence along the first direction X, so that the first surfaces 111 and the second surfaces 112 of the multiple batteries 100 are arranged alternately in sequence along the first direction X, so that the two adjacent batteries 100 are arranged in a structure with the first surfaces 111 and the second surfaces 112 facing each other.

[0109] The first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100 are arranged along the second direction Y. That is, in two adjacent batteries 100, the first fixing portion 113 of one battery 100 is located on one side of the second fixing portion 114 of the other battery 100 in the second direction Y.

[0110] In this embodiment, the electrical device is provided with a plurality of batteries 100, which are arranged along a first direction X. In addition, in two adjacent batteries 100, the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100 are arranged along a second direction Y. Such that the first fixing portion 113 of one battery 100 is located on one side of the second fixing portion 114 of the other battery 100 in the second direction Y, so that the first fixing portion 113 and the second fixing portion 114 of the two adjacent batteries 100 can avoid each other. This enables the plurality of batteries 100 to share a portion of space in the first direction X, thereby reducing the overall size of the plurality of batteries 100 arranged along the first direction X. This can save space occupied by the plurality of batteries 100 on the electrical device, thereby improving space utilization of the plurality of batteries 100.

[0111] In some embodiments, referring to Figures 4 and 7 , along the first direction X, in two adjacent batteries 100, the distance between the first surface 111 and the second surface 112 is L1, the dimension of the first fixing portion 113 protruding from the first surface 111 is L2, and the dimension of the second fixing portion 114 protruding from the second surface 112 is L3, satisfying 1.1L2≤L1≤1.6L2, and 1.1L3≤L1≤1.6L3.

[0112] Exemplarily, in FIG. 4 and FIG. 7 , a dimension L2 of the first fixing portion 113 protruding from the first surface 111 is equal to a dimension L3 of the second fixing portion 114 protruding from the second surface 112 .

[0113] Exemplarily, the distance L1 between the first surface 111 and the second surface 112 is 1.5 times the dimension L2 of the first fixing portion 113 protruding from the first surface 111 .

[0114] In this embodiment, in two adjacent batteries 100, by setting the distance between the first surface 111 of one battery 100 and the second surface 112 of the other battery 100 to be greater than or equal to 1.1 times the size of the first fixing portion 113 protruding on the first surface 111, the phenomenon of too small assembly space between the first surface 111 of one battery 100 and the second surface 112 of the other battery 100 is alleviated, thereby reducing the interference and scratching between the first fixing portion 113 of one battery 100 and the second surface 112 of the other battery 100, which is beneficial. In order to reduce the difficulty of sequentially assembling multiple batteries 100 along the first direction X, the distance between the first surface 111 of one battery 100 and the second surface 112 of another battery 100 is set to be less than or equal to 1.6 times the size of the first fixing portion 113 protruding from the first surface 111, thereby alleviating the phenomenon that the reserved assembly gap between the first surface 111 of one battery 100 and the second surface 112 of another battery 100 is too large, thereby saving the space occupied by the multiple batteries 100 in the first direction X, which is conducive to further improving the space utilization of the batteries 100. Similarly, by setting the distance between the first surface 111 of one battery 100 and the second surface 112 of another battery 100 to be greater than or equal to 1.1 times the size of the second fixing portion 114 protruding from the second surface 112, the phenomenon of too small assembly space between the first surface 111 of one battery 100 and the second surface 112 of another battery 100 is alleviated, thereby reducing interference and scratching between the second fixing portion 114 of one battery 100 and the first surface 111 of another battery 100, which helps to reduce the difficulty of assembling multiple batteries 100 sequentially along the first direction X. By setting the distance between the first surface 111 of one battery 100 and the second surface 112 of another battery 100 to be less than or equal to 1.6 times the size of the second fixing portion 114 protruding from the second surface 112, the phenomenon of too large reserved assembly gap between the first surface 111 of one battery 100 and the second surface 112 of another battery 100 is alleviated, thereby saving the space occupied by multiple batteries 100 in the first direction X, which helps to further improve the space utilization of the batteries 100.

[0115] According to some embodiments of the present application, referring to Figures 2, 3, and 4, the electrical device further includes a target part and a locking mechanism 400. The locking mechanism 400 is disposed on two adjacent batteries 100 along a first direction X. In the two adjacent batteries 100, the locking mechanism 400 connects the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100, and the locking mechanism 400 is used to engage or disengage with the target part along a third direction Z to lock or unlock the box 10 with the target part. The third direction Z is perpendicular to the first direction X and the second direction Y.

[0116] Among them, the vehicle 1000 has a mounting frame 200, the target part is the lock seat 300 of the vehicle 1000, the lock seat 300 is installed on the mounting frame 200 of the vehicle 1000, and the locking mechanism 400 is used to engage or disengage with the lock seat 300 along the third direction Z, so that the battery 100 can be assembled to the vehicle 1000 through the locking mechanism 400.

[0117] Optionally, the lock base 300 and the mounting frame 200 may be integral or separate. When the lock base 300 and the mounting frame 200 are integral, the lock base 300 is a part of the mounting frame 200, meaning the target object is also the mounting frame 200. When the lock base 300 and the mounting frame 200 are separate, the lock base 300 may be connected to the mounting frame 200 by welding, bolting, or clamping.

[0118] The locking mechanism 400 is disposed on two adjacent batteries 100 , that is, two adjacent batteries 100 in the first direction X are connected to the same locking mechanism 400 .

[0119] In two adjacent batteries 100, the locking mechanism 400 connects the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100. That is, in two adjacent batteries 100, the first fixing portion 113 of one battery 100 is a structure that is assembled into an integral whole with the second fixing portion 114 of the other battery 100 through the locking mechanism 400, so that the locking mechanism 400 is connected to both the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100, thereby enabling multiple batteries 100 to be assembled into a whole before battery replacement.

[0120] It should be noted that, in other embodiments, each battery 100 may be provided with a locking mechanism 400, that is, the first fixing portion 113 of each battery 100 is provided with at least one locking mechanism 400, and the second fixing portion 114 of each battery 100 is provided with at least one locking mechanism 400, so that each battery 100 is an independently assembled structure.

[0121] In this embodiment, the locking mechanism 400 of the electrical device is a structure that connects the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100 in two adjacent batteries 100, so that the first fixing portion 113 and the second fixing portion 114 in the two adjacent batteries 100 share a locking mechanism 400, and are locked to the target part through the locking mechanism 400. The electrical device using this structure can simultaneously lock or unlock the two adjacent batteries 100, and can first assemble the two adjacent batteries 100 and the locking mechanism 400 into a whole and then lock them with the target part to achieve The battery replacement of multiple batteries 100 can, on the one hand, further optimize and reduce the assembly space reserved between the multiple batteries 100, so as to further increase the tightness of the mutual assembly between the multiple batteries 100, which is beneficial to improving the space utilization rate of the battery 100. On the other hand, a locking mechanism 400 is used to lock or unlock two adjacent batteries 100, so that there is no need to lock or unlock the multiple batteries 100 multiple times, so that the locking or unlocking actions required for the multiple batteries 100 during the battery replacement process are reduced, which is beneficial to optimizing the battery replacement rhythm of the multiple batteries 100, thereby improving the battery replacement efficiency of the battery 100 and saving the battery replacement cost.

[0122] According to some embodiments of the present application, referring to Figures 3 and 4, and further referring to Figures 8, 9, and 10, Figure 8 is a schematic structural diagram of a locking mechanism 400 provided in some embodiments of the present application, Figure 9 is an exploded structural diagram of the locking mechanism 400 provided in some embodiments of the present application, and Figure 10 is a cross-sectional view of the locking mechanism 400 provided in some embodiments of the present application. The locking mechanism 400 may include a locking sleeve 30, an adjustment member 40, and two locking members 50. Along a first direction X, in two adjacent batteries 100, the locking sleeve 30 connects the first fixing portion 113 of one battery 100 to the second fixing portion 114 of the other battery 100. Along the first direction X, in two adjacent batteries 100, two locking members 50 are respectively disposed through the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100. Both locking members 50 are movably disposed on the lock sleeve 30. The locking members 50 have a locked state and an unlocked state. When in the locked state, the locking members 50 are configured to engage with the target member to allow the locking mechanism 400 to engage with the target member along the third direction Z. When in the unlocked state, the locking members 50 are configured to disengage from the target member to allow the locking mechanism 400 to disengage from the target member along the third direction Z. An adjustment member 40 is disposed on the lock sleeve 30 and is configured to drive the two locking members 50 to move relative to the lock sleeve 30 to switch the locking members 50 between the locked state and the unlocked state.

[0123] The locking sleeve 30 connects two adjacent batteries 100 in the first direction X and serves as a mounting for the adjusting member 40 and the locking member 50, so that the locking mechanism 400 can lock the battery 100 to the locking base 300 via the locking member 50. The locking sleeve 30 is a hollow structure to enable the mounting of the adjusting member 40 and the locking member 50.

[0124] Exemplarily, the lock sleeve 30 can be made of various materials, such as steel, aluminum, iron, aluminum alloy, or plastic.

[0125] In two adjacent batteries 100, the locking sleeve 30 connects the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100. That is, in Figures 3 and 4, when the multiple batteries 100 are arranged along the first direction X and the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100 are arranged along the second direction Y, the locking sleeve 30 of the locking mechanism 400 can connect to the first fixing portion 113 and the second fixing portion 114 adjacent to each other in the second direction Y.

[0126] In two adjacent batteries 100, the two locking members 50 are respectively disposed through the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100. In other words, the two locking members 50 of the locking mechanism 400 are respectively structured to penetrate the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100, thereby facilitating the locking of the two adjacent batteries 100 to the lock base 300. Specifically, one locking member 50 of the locking mechanism 400 penetrates the upper surface of the first fixing portion 113 of one battery 100 along the third direction Z, and the other locking member 50 penetrates the upper surface of the second fixing portion 114 of the other battery 100 along the third direction Z.

[0127] The locking member 50 is used to engage or disengage with the lock base 300 so that the locking mechanism 400 can engage or disengage with the lock base 300 along the third direction Z through the locking member 50 to achieve locking or unlocking between the locking mechanism 400 and the lock base 300.

[0128] The locking member 50 is movable relative to the lock sleeve 30, such that the locking member 50 has a locked state in which it can be engaged with the lock base 300 and an unlocked state in which it can be disengaged from the lock base 300. For example, in Figures 9 and 10, the locking member 50 includes a connecting portion 51 and a clamping portion 52 that are interconnected. The connecting portion 51 is a cylindrical structure extending along the third direction Z and is inserted into the lock sleeve 30 along the third direction Z. The connecting portion 51 is in transmission connection with the adjustment member 40. The clamping portion 52 is connected to an end of the connecting portion 51 that extends out of the lock sleeve 30 in the third direction Z. The clamping portion 52 functions to be mutually engaged with the lock base 300. The extending direction of the clamping portion 52 is perpendicular to the third direction Z, so that the locking member 50 has an irregular structure that can rotate about an axis extending in the third direction Z. Rotating the connecting portion 51 can drive the clamping portion 52 to rotate, so that the clamping portion 52 can be engaged with or disengaged from the lock base 300. Of course, in other embodiments, the locking portion 52 of the locking member 50 may also be a retractable structure in a direction perpendicular to the third direction Z, so that the locking member 50 can be engaged with or disengaged from the lock seat 300 through the locking portion 52.

[0129] The adjusting member 40 is configured to drive the two locking members 50 to move relative to the lock sleeve 30, so that the locking members 50 switch between the locked state and the unlocked state. In other words, the adjusting member 40 can drive the two locking members 50 to move relative to the lock sleeve 30, so that the locking members 50 switch between the locked state and the unlocked state. For example, in Figures 9 and 10, the adjusting member 40 can drive the connecting portion 51 of the locking member 50 to rotate relative to the lock sleeve 30, so that the connecting portion 51 drives the clamping portion 52 to rotate, thereby enabling the clamping portion 52, whose extending direction is perpendicular to the third direction Z, to rotate within a plane perpendicular to the third direction Z, thereby enabling the clamping portion 52 to engage or disengage with the lock base 300, so that the locking member 50 switches between the locked state and the unlocked state.

[0130] The locking member 50 of the second locking part 50 is driven by the adjusting member 40, and the locking member 50 of the second locking part 50 is driven by the adjusting member 40.

[0131] For example, in Figures 9 and 10, the locking mechanism 400 is further provided with a transmission assembly 60, so that the adjusting member 40 is a structure that is transmission-connected to the locking member 50 through the transmission assembly 60, so that the adjusting member 40 can individually drive each locking member 50 to move relative to the locking sleeve 30 or simultaneously drive the two locking members 50 to move relative to the locking sleeve 30, so that the adjusting member 40 and the locking member 50 are indirectly connected through the transmission assembly 60. Of course, in other embodiments, the adjusting member 40 may also be a structure that is directly connected to the locking member 50.

[0132] In this embodiment, the locking mechanism 400 is provided with a lock sleeve 30, an adjusting member 40 and two locking members 50. By connecting the lock sleeve 30 to the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100 of the two adjacent batteries 100, the first fixing portion 113 and the second fixing portion 114 of the two adjacent batteries 100 can share a locking mechanism 400 and be connected to each other as a whole for battery replacement. In addition, the two locking members 50 are respectively provided in the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100, and the adjusting member 40 can drive The two locking members 50 are switched between a locked state and an unlocked state, so that the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100 of the two adjacent batteries 100 are locked with the target member, so that while improving the stability of the mutual locking between the battery 100 and the target member, the two locking members 50 can also be moved between unlocking and locking through an adjustment member 40, which is beneficial to further reduce the locking or unlocking actions required for multiple batteries 100 during the battery replacement process, and can further improve the operating efficiency of the locking mechanism 400 and the battery replacement efficiency of the battery 100.

[0133] According to some embodiments of the present application, as shown in Figures 9 and 10, the locking mechanism 400 may further include a transmission assembly 60. The transmission assembly 60 is disposed within the lock sleeve 30, and the two locking members 50 are selectively connected to the adjustment member 40 through the transmission assembly 60. The adjustment member 40 is rotatably disposed on the lock sleeve 30 about an axis extending along the third direction Z. The adjustment member 40 is configured to independently drive each locking member 50 to move relative to the lock sleeve 30 when rotating relative to the lock sleeve 30, thereby switching the locking members 50 between a locked state and an unlocked state.

[0134] The transmission assembly 60 plays a role in transmitting and connecting the adjusting member 40 and one of the two locking members 50 , so that the adjusting member 40 can independently drive each locking member 50 to move relative to the locking sleeve 30 through the transmission assembly 60 .

[0135] The two locking members 50 are selectively transmission-connected to the adjusting member 40 via the transmission assembly 60 , that is, the adjusting member 40 is selectively transmission-connected to one of the two locking members 50 via the transmission assembly 60 .

[0136] The adjusting member 40 is rotatably disposed on the lock sleeve 30 about an axis extending along the third direction Z. The adjusting member 40 is configured to individually drive each locking member 50 to move relative to the lock sleeve 30 when rotating relative to the lock sleeve 30, thereby switching the locking members 50 between a locked state and an unlocked state. In other words, the adjusting member 40 is rotatable relative to the lock sleeve 30 about an axis extending along the third direction Z. By rotating the adjusting member 40, the corresponding locking member 50 can be driven to move relative to the lock sleeve 30 via the transmission assembly 60, thereby switching the locking members 50 between a locked state and an unlocked state. Of course, in other embodiments, the adjusting member 40 can also be a structure that moves relative to the lock sleeve 30 to enable the locking members 50 to move relative to the lock sleeve 30.

[0137] In FIG10 , the adjusting member 40 is rotatably inserted into the lock sleeve 30 along the third direction Z, and a portion of the adjusting member 40 passes through one end of the lock sleeve 30 away from the clamping portion 52 of the locking member 50 along the third direction Z, so that the portion of the adjusting member 40 extending out of the lock sleeve 30 can be operated by the user to drive the adjusting member 40 to rotate relative to the lock sleeve 30 to switch the state of the locking member 50.

[0138] In this embodiment, a transmission assembly 60 is provided in the lock sleeve 30 of the locking mechanism 400, and the multiple locking members 50 of the locking mechanism 400 are a structure that is selectively connected to the adjusting member 40 through the transmission assembly 60, so that the adjusting member 40 can be selectively connected to one of the multiple locking members 50 through the transmission assembly 60, so that the adjusting member 40 can individually drive one of the multiple locking members 50 to move relative to the lock sleeve 30 when the adjusting member 40 rotates relative to the lock sleeve 30, so that the adjusting member 40 can individually drive the single locking member 50 to switch between the locked state and the unlocked state.

[0139] According to some embodiments of the present application, please continue to refer to Figures 9 and 10 , the transmission assembly 60 may include a first gear 61 and two second gears 62. The first gear 61 is fixedly sleeved on the outside of the adjustment member 40. The two second gears 62 are selectively engaged with the first gear 61, and each second gear 62 is connected to a locking member 50. The adjustment member 40 is configured to drive the corresponding second gear 62 to rotate when the first gear 61 is engaged with the second gear 62, so as to drive the corresponding locking member 50 to move relative to the locking sleeve 30, so that the locking member 50 can switch between a locked state and an unlocked state.

[0140] Among them, the first gear 61 is fixedly sleeved on the outside of the adjusting part 40, that is, the first gear 61 is a structure sleeved on the outside of the adjusting part 40, and the first gear 61 is fixedly connected to the adjusting part 40, so that the first gear 61 and the adjusting part 40 are circumferentially locked and axially locked along the third direction Z.

[0141] For example, the first gear 61 may be assembled on the adjusting member 40 in various structures. For example, the first gear 61 and the adjusting member 40 may be connected to each other by welding, interference fit, or bonding.

[0142] The two second gears 62 selectively mesh with the first gear 61, that is, the first gear 61 mounted on the adjusting member 40 can selectively mesh with one of the two second gears 62. Each second gear 62 is connected to a second gear 62, so that the first gear 61 mounted on the adjusting member 40 can selectively mesh with the second gears 62 connected to different locking members 50.

[0143] The adjusting member 40 is configured to drive the corresponding second gear 62 to rotate when the first gear 61 is engaged with the second gear 62, so as to drive the corresponding locking member 50 to move relative to the locking sleeve 30. That is, when the first gear 61 provided on the adjusting member 40 is engaged with one of the two second gears 62, the corresponding second gear 62 can be driven to rotate relative to the locking sleeve 30 by rotating the adjusting member 40, so as to further drive the locking member 50 connected to the second gear 62 to move relative to the locking sleeve 30, so that the corresponding locking member 50 can switch between the locked state and the unlocked state, thereby realizing that the adjusting member 40 can individually drive each locking member 50 to switch between the locked state and the unlocked state.

[0144] It should be noted that there may be various structures in which the two second gears 62 selectively engage with the first gear 61. The two second gears 62 may be movably arranged in the lock sleeve 30, so that by moving different second gears 62 to engage with the first gear 61, the two second gears 62 can be selectively engaged with the first gear 61. For example, the second gear 62 is movably connected to the connecting portion 51 of the locking member 50 along the third direction Z, and the second gear 62 is circumferentially locked with the locking member 50. Of course, the adjusting member 40 may also be movably arranged in the lock sleeve 30, so that by moving the adjusting member 40 to drive the first gear 61 to move in the lock sleeve 30, the first gear 61 can be selectively engaged with one of the two second gears 62.

[0145] In this embodiment, the transmission assembly 60 is provided with a first gear 61 and two second gears 62. The first gear 61 is fixedly mounted on the adjusting member 40, and each second gear 62 is connected to a locking member 50, and the two second gears 62 can selectively engage with the second gear 62, so that the first gear 61 mounted on the adjusting member 40 can selectively engage with one of the two second gears 62, so that when the adjusting member 40 rotates relative to the locking sleeve 30, the corresponding locking member 50 can be driven to move relative to the locking sleeve 30 through the mutual engagement of the first gear 61 and the second gear 62, thereby realizing that the adjusting member 40 can individually drive each locking member 50 to switch between the locked state and the unlocked state through the transmission assembly 60. The structure is simple and easy to implement.

[0146] In some embodiments, as shown in FIG. 10 , the adjustment member 40 is movably disposed on the lock sleeve 30 along the third direction Z. The adjustment member 40 is configured to move along the third direction Z to drive the first gear 61 to selectively engage with one of the two second gears 62 .

[0147] The adjusting member 40 is movably disposed on the lock sleeve 30 along the third direction Z. Movement of the adjusting member 40 along the third direction Z drives the first gear 61, which is sleeved on the outer side of the adjusting member 40, to move along the third direction Z, so that the first gear 61 can sequentially engage with different ones of the two second gears 62. In other words, the two second gears 62 are staggered in the third direction Z, so that the first gear 61 can engage with different ones of the second gears 62 as it moves along the third direction Z.

[0148] Optionally, as shown in Figures 9 and 10, the second gear 62 may include a main body 621 and a toothed portion 622, the main body 621 is connected to the locking member 50, and the toothed portion 622 is fixedly sleeved on the outer side of the main body 621, and the toothed portion 622 includes a plurality of teeth arranged in sequence along the circumference of the main body 621, and the plurality of teeth of the toothed portion 622 all extend along the third direction Z so that the toothed portion 622 can engage with the first gear 61, and the toothed portions 622 of the two second gears 62 are arranged at intervals along the third direction Z.

[0149] Among them, the tooth-shaped portions 622 of the two second gears 62 are arranged at intervals along the third direction Z, so that the first gear 61 can engage with the tooth-shaped portions 622 of different second gears 62 when moving along the third direction Z, so as to realize that the first gear 61 can selectively engage with one of the two second gears 62.

[0150] Exemplarily, the main body 621 and the locking member 50 are threadedly connected. The main body 621 of the second gear 62 is sleeved on the outside of the connecting portion 51 of the locking member 50 and is threadedly connected to the connecting portion 51 of the locking member 50, so that when the second gear 62 rotates, it can drive the connecting portion 51 of the locking member 50 to rotate relative to the locking sleeve 30, so as to drive the clamping portion 52 of the locking member 50 to be clamped or released from the lock seat 300, and when the rotation of the connecting portion 51 of the locking member 50 relative to the locking sleeve 30 is restricted, the second gear 62 can also apply a feed force along the third direction Z to the connecting portion 51 of the locking member 50 through the threaded structure, so as to drive the connecting portion 51 to move along the third direction Z.

[0151] It should be noted that, in other embodiments, the toothed portions 622 of multiple second gears 62 may also be a structure located at the same position in the third direction Z, so that the first gear 61 of the adjusting member 40 is a structure that is simultaneously engaged with the toothed portions 622 of the two second gears 62. The locking mechanism 400 adopting this structure can simultaneously drive the two second gears 62 to rotate relative to the locking sleeve 30 through the adjusting member 40, so as to drive the two locking members 50 to move relative to the locking sleeve 30 at the same time, thereby realizing the simultaneous switching of the two locking members 50 between the locked state and the unlocked state.

[0152] In this embodiment, by setting the adjusting member 40 as a structure that is movably arranged in the lock sleeve 30 along the third direction Z, the adjusting member 40 can drive the first gear 61 to move along the third direction Z when moving along the third direction Z, so that the first gear 61 can engage with different second gears 62 during the process of moving along the third direction Z, thereby achieving that the first gear 61 provided on the adjusting member 40 can selectively engage with one of the two second gears 62, the structure is simple, and easy to assemble.

[0153] According to some embodiments of the present application, as shown in Figures 8, 9, and 10, the locking member 50 may include a connecting portion 51 and a clamping portion 52. The connecting portion 51 extends along the third direction Z and is inserted into the lock sleeve 30. The connecting portion 51 is connected to the second gear 62. The clamping portion 52 is located outside the lock sleeve 30 and is connected to the end of the connecting portion 51 away from the lock sleeve 30. The clamping portion 52 protrudes from the outer circumference of the connecting portion 51 along its extension direction. The clamping portion 52 is configured to engage with the lock base 300, and the extension direction of the clamping portion 52 is perpendicular to the third direction Z. The second gear 62 is configured to rotate relative to the lock sleeve 30 to drive the corresponding connecting portion 51 of the locking member 50 to rotate, thereby engaging or disengaging the clamping portion 52 with the lock base 300, thereby switching the locking member 50 between a locked state and an unlocked state.

[0154] The connecting portion 51 of the locking member 50 is a cylindrical structure extending along the third direction Z. A portion of the connecting portion 51 is inserted into the locking sleeve 30 along the third direction Z, and the end of the connecting portion 51 extending out of the locking sleeve 30 is connected to the clamping portion 52. The end of the connecting portion 51 in the third direction Z that is away from the clamping portion 52 is connected to the main body 621 of the second gear 62. The main body 621 of the second gear 62 is threadedly connected to the outer side of the clamping portion 52. In other words, the portion of the connecting portion 51 inserted into the main body 621 of the first gear 61 is provided with external threads, and correspondingly, the main body 621 of the first gear 61 is provided with internal threads, allowing the main body 621 of the second gear 62 to be threadedly connected to the outer side of the clamping portion 52. Of course, in other embodiments, the connecting portion 51 may be screwed to the outside of the main body 621, that is, the connecting portion 51 is provided with an internal thread, and correspondingly, the portion of the main body 621 of the first gear 61 accommodated in the connecting portion 51 is provided with an external thread, so that the connecting portion 51 can be screwed to the outside of the main body 621.

[0155] The clamping portion 52 is located outside the locking sleeve 30 and is connected to one end of the connecting portion 51 away from the locking sleeve 30, that is, the connecting portion 51 has a portion extending out of the locking sleeve 30 in the third direction Z, and the clamping portion 52 is connected to one end of the portion of the connecting portion 51 extending out of the locking sleeve 30, so that the clamping portion 52 is arranged at an interval from the locking sleeve 30 along the third direction Z.

[0156] The clamping portion 52 protrudes from the outer peripheral surface of the connecting portion 51 along its extension direction. That is, in the extension direction of the clamping portion 52, the clamping portion 52 extends beyond the outer peripheral surface of the connecting portion 51. For example, in Figure 10, the extension direction of the clamping portion 52 is perpendicular to the third direction Z, so that the clamping portion 52 and the connecting portion 51 form a "T"-shaped structure.

[0157] For example, in Figures 9 and 10, the connecting portion 51 and the clamping portion 52 are an integrally formed structure, and the connecting portion 51 and the clamping portion 52 can be made by an integral forming process such as casting or milling. Of course, in other embodiments, the connecting portion 51 and the clamping portion 52 can also be separately arranged structures, and the clamping portion 52 can be connected to the connecting portion 51 by a threaded connection, a welding connection, or a clamping connection.

[0158] The second gear 62 is configured to drive the corresponding connecting portion 51 of the locking member 50 to rotate when it rotates relative to the lock sleeve 30, so that the clamping portion 52 is clamped or released from the lock base 300, so that the locking member 50 switches between the locked state and the unlocked state, that is, the adjusting member 40 is able to drive the first gear 61 to rotate when it rotates relative to the lock sleeve 30, so as to drive the second gear 62 engaged with the first gear 61 to rotate, so that the second gear 62 can drive the corresponding connecting portion 51 of the locking member 50 to rotate around the axis extending along the third direction Z, and thus can change the extension direction of the clamping portion 52, so that the clamping portion 52 can overlap the lock base 300 or release the overlap from the lock base 300, so that the clamping portion 52 can be clamped or released from the lock base 300.

[0159] In some embodiments, referring to Figures 9 and 10, and further referring to Figure 11, Figure 11 is a schematic diagram of the assembly of the lock base 300 and the locking member 50 of the locking mechanism 400 provided in some embodiments of the present application, which are locked to each other. The lock base 300 is provided with a lock hole 301 for the locking member 50 to be inserted. The lock hole 301 passes through both sides of the lock base 300 along the third direction Z. After the locking member 50 is inserted into the lock hole 301, the rotating adjustment member 40 can drive the corresponding locking member 50's clamping portion 52 to rotate around the axis extending along the third direction Z through the transmission assembly 60, so that the clamping portion 52 can engage with the surface of the lock base 300 on the side away from the lock sleeve 30, so that the locking mechanism 400 and the lock base 300 engage in the third direction Z, thereby achieving mutual locking between the locking mechanism 400 and the lock base 300, so as to achieve the desired effect. The two batteries 100 adjacent to each other in the first direction X are locked on the lock seat 300 of the mounting bracket 200. Conversely, when the rotating adjustment member 40 drives the corresponding locking member 50's clamping portion 52 to rotate through the transmission assembly 60 until the projection of the clamping portion 52 in the third direction Z is located in the lock hole 301, the locking member 50 can be withdrawn from the lock hole 301, so that the locking mechanism 400 and the lock seat 300 can be disengaged in the third direction Z, thereby realizing mutual unlocking between the locking mechanism 400 and the lock seat 300, so that the two batteries 100 adjacent to each other in the first direction X can be replaced.

[0160] Among them, the cross-section of the lock hole 301 is rectangular. When the extension direction of the clamping portion 52 is consistent with the length direction of the cross-section of the lock hole 301, the clamping portion 52 can be inserted into the lock hole 301 or can be withdrawn from the lock hole 301. When the clamping portion 52 passes through the lock hole 301 and the extension direction of the clamping portion 52 intersects with the length direction of the cross-section of the lock hole 301, the clamping portion 52 can be engaged with the surface of the lock seat 300 on the side facing away from the lock sleeve 30.

[0161] Optionally, a card slot 302 is further provided on the surface of the lock seat 300 for the engaging of the card portion 52, and the extension direction of the card slot 302 is perpendicular to the length direction of the cross section of the lock hole 301. When the card portion 52 is rotated so that the extension direction is perpendicular to the length direction of the cross section of the lock hole 301, the card portion 52 can engage with the lock seat 300, and the card slot 302 can be inserted into the card portion 52 to alleviate the shaking phenomenon between the locking mechanism 400 and the lock seat 300, thereby helping to improve the stability of the mutual locking of the locking mechanism 400 and the lock seat 300.

[0162] The locking member 50 is provided with a connecting portion 51 and a clamping portion 52 connected to one end of the connecting portion 51, and the clamping portion 52 protrudes from the outer peripheral surface of the connecting portion 51 in its extension direction. By inserting the connecting portion 51 into the lock sleeve 30 along the third direction Z and connecting the second gear 62 to each other, the adjusting member 40 can drive the corresponding second gear 62 to rotate when the first gear 61 and the second gear 62 are engaged, so as to drive the connecting portion 51 of the corresponding locking member 50 to rotate relative to the lock sleeve 30, so that the clamping portion 52 can rotate with the connecting portion 51, thereby realizing that the extension direction of the clamping portion 52 is changed in a plane perpendicular to the third direction Z, so that the clamping portion 52 can be clamped or released with the lock seat 300 after rotation, thereby realizing that the locking member 50 of the locking mechanism 400 can be engaged with or disengaged from the lock seat 300 in the third direction Z.

[0163] According to some embodiments of the present application, referring to Figures 9 and 10, and further referring to Figure 12, which is a cross-sectional view of a locking sleeve 30 of a locking mechanism 400 provided in some embodiments of the present application, the locking sleeve 30 is provided with a first limiting portion 31, and the connecting portion 51 is provided with a second limiting portion 511. The first limiting portion 31 and the second limiting portion 511 cooperate to limit the rotation angle of the locking member 50.

[0164] Among them, the first limiting portion 31 and the second limiting portion 511 play the role of cooperating to limit the rotation angle of the connecting portion 51 relative to the locking sleeve 30. The structures of the first limiting portion 31 and the second limiting portion 511 can be various. For example, the first limiting portion 31 can be a limiting groove 32 provided on the inner circumference of the locking sleeve 30, and correspondingly, the second limiting portion 511 can be a limiting protrusion 512 convexly provided on the outer circumference of the connecting portion 51. The limiting protrusion 512 is inserted into the limiting groove 32 to cooperate with the connecting portion 51. The rotation angle of the connecting portion 51 is limited. Of course, the first limiting portion 31 and the second limiting portion 511 can also be limiting protrusions 512. The first limiting portion 31 is protruded at one end of the lock sleeve 30 in the third direction Z, and the second limiting portion 511 is protruded at the outer peripheral surface of the connecting portion 51. The second limiting portion 511 can abut against the first limiting portion 31 when the connecting portion 51 rotates relative to the lock sleeve 30, so as to limit the rotation angle of the connecting portion 51 through the mutual cooperation of the first limiting portion 31 and the second limiting portion 511.

[0165] Optionally, the number of the first limiting portions 31 and the second limiting portions 511 provided between each locking member 50 and the locking sleeve 30 may be one or more. For example, in Figures 9 and 10, two second limiting portions 511 are provided on the connecting portion 51 of each locking member 50, and the two second limiting portions 511 are respectively provided on both sides of the connecting portion 51 along the radial direction of the connecting portion 51. Correspondingly, the locking sleeve 30 is provided with two first limiting portions 31 corresponding to each locking member 50.

[0166] In this embodiment, by correspondingly providing the first limiting portion 31 and the second limiting portion 511 on the lock sleeve 30 and the connecting portion 51 respectively, the first limiting portion 31 and the second limiting portion 511 can cooperate to limit the rotation angle of the connecting portion 51, so that the connecting portion 51 drives the clamping portion 52 to be clamped or released with the lock seat 300 under the cooperation restriction of the first limiting portion 31 and the second limiting portion 511, thereby facilitating the switching of the locking member 50 between the locked state and the unlocked state. The structure is simple and easy to operate, and can alleviate the phenomenon that the clamping portion 52 cannot be clamped with the lock seat 300 due to the excessive rotation angle of the clamping portion 52 following the connecting portion 51, which is beneficial to improving the reliability of the mutual locking between the locking mechanism 400 and the lock seat 300.

[0167] According to some embodiments of the present application, as shown in Figures 9, 10, and 11, the connecting portion 51 is threadedly connected to the second gear 62, and the first limiting portion 31 and the second limiting portion 511 are further configured to cooperate and guide the connecting portion 51 to move along the third direction Z when the second gear 62 drives the corresponding locking member 50 to rotate, so that the locking member 50 moves between the first position and the second position along the third direction Z. When the locking member 50 is in the first position, the locking member 50 is in a locked state, so that the engaging portion 52 can engage with the lock base 300; when the locking member 50 is in the second position, the locking member 50 is in an unlocked state, so that the engaging portion 52 can be released from the lock base 300.

[0168] The first limiting portion 31 and the second limiting portion 511 are further configured to cooperate and guide the connecting portion 51 to move along the third direction Z when the second gear 62 drives the corresponding locking member 50 to rotate. That is, in the process of the adjusting member 40 driving the corresponding connecting portion 51 to rotate relative to the lock sleeve 30 through the transmission assembly 60, the first limiting portion 31 and the second limiting portion 511 cooperate to limit the rotation angle of the connecting portion 51 while guiding the connecting portion 51 to move relative to the lock sleeve 30 in the third direction Z, so that the locking member 50 has two end positions relative to the lock sleeve 30 in the third direction Z, namely the first position and the second position. The second position, that is, while the adjusting member 40 drives the corresponding connecting portion 51 to rotate relative to the lock sleeve 30 through the transmission assembly 60, the connecting portion 51 can also move relative to the lock sleeve 30 along the third direction Z, so that when the connecting portion 51 drives the clamping portion 52 to rotate until the clamping portion 52 can engage with the side of the lock seat 300 away from the lock sleeve 30, the locking member 50 is in the first position. Correspondingly, when the locking member 50 moves to the second position, the projection of the clamping portion 52 in the third direction Z is located in the lock hole 301 of the lock seat 300, so that the locking member 50 can disengage from the lock seat 300 along the third direction Z.

[0169] When the adjusting member 40 rotates relative to the locking sleeve 30, it can drive the connecting part 51 to rotate and move along the third direction Z through the transmission assembly 60. For example, in Figure 10, the main body 621 of the second gear 62 of the transmission assembly 60 and the connecting part 51 are connected by a threaded structure, so that the adjusting member 40 can drive the corresponding connecting part 51 to rotate through the transmission assembly 60, and when the circumferential rotation of the connecting part 51 is restricted, the second gear 62 can provide the connecting part 51 with a feed force along the third direction Z, so that the connecting part 51 can move along the third direction Z.

[0170] In this embodiment, by setting the connecting part 51 and the second gear 62 as a structure in which the connection part 51 is threadedly connected to each other, the locking mechanism 400 adopting such a structure enables the second gear 62 to apply a feed force to the connecting part 51 to move along the third direction Z when the rotation of the connecting part 51 is restricted, so that the first limiting part 31 and the second limiting part 511 can not only limit the rotation angle of the connecting part 51, but also cooperate to guide the connecting part 51 to move relative to the lock sleeve 30 in the third direction Z, so that the adjusting part 40 can drive the connecting part 51 to rotate relative to the lock sleeve 30 through the first gear 61 and the second gear 62, and can also drive the locking part 50 to move between the first position and the second position along the third direction Z, so that the adjusting part 40 can drive the clamping part 52 to clamp with the lock seat 300 while also driving the clamping part 52 and the lock seat 300 to abut against each other, so as to reduce the size of the gap between the clamping part 52 and the lock seat 300, which is beneficial to reduce vibration or impact between the locking mechanism 400 and the lock seat 300.

[0171] According to some embodiments of the present application, please refer to Figures 9, 10 and 12, the first limiting portion 31 is a limiting groove 32 arranged on the inner circumferential surface of the locking sleeve 30, and the second limiting portion 511 is a limiting protrusion 512 protruding from the outer circumferential surface of the connecting portion 51, and at least a portion of the limiting protrusion 512 is accommodated in the limiting groove 32.

[0172] Among them, the first limiting portion 31 is a limiting groove 32, and the second limiting portion 511 is a limiting protrusion 512. By inserting the limiting protrusion 512 into the limiting groove 32, the movement trajectory of the limiting protrusion 512 will be restricted and guided by the limiting groove 32, so that the connecting portion 51 can achieve the limitation of the rotation angle and move between the first position and the second position along the third direction Z under the cooperation of the first limiting portion 31 and the second limiting portion 511.

[0173] For example, in Figures 9 and 11, the limiting groove 32 provided on the lock sleeve 30 passes through the outer peripheral surface of the lock sleeve 30, so that the limiting groove 32 can be formed on the inner peripheral surface of the lock sleeve 30, which is conducive to reducing the manufacturing difficulty and facilitating the limiting protrusion 512 to be inserted into the limiting groove 32.

[0174] In this embodiment, the first limiting portion 31 and the second limiting portion 511 are respectively provided with a limiting groove 32 on the inner circumferential surface of the locking sleeve 30 and a limiting protrusion 512 on the outer circumferential surface of the connecting portion 51. By inserting the limiting protrusion 512 into the limiting groove 32, the rotation angle of the connecting portion 51 can be limited under the restriction of the limiting groove 32, and the limiting protrusion 512 can realize the rotation of the connecting portion 51 relative to the locking sleeve 30 under the guidance of the limiting groove 32, and can also move relative to the locking sleeve 30 along the third direction Z. The structure is simple, easy to implement, and has high stability.

[0175] In some embodiments, referring to Figures 9, 10, and 12, the limiting groove 32 may include a first groove section 321, a second groove section 322, and a third groove section 323 connected in sequence. The first groove section 321 and the third groove section 323 both extend along the third direction Z. The first groove section 321 and the third groove section 323 are spaced apart along the circumference of the connecting portion 51, and the first groove section 321 and the third groove section 323 are spaced apart along the third direction Z. Along the third direction Z, the third groove section 323 is closer to the engaging portion 52 than the first groove section 321. When the locking member 50 is in the first position, the limiting protrusion 512 is located in the first groove section 321. When the locking member 50 is in the second position, the limiting protrusion 512 is located in the third groove section 323.

[0176] Among them, the first groove segment 321 and the third groove segment 323 are arranged at intervals along the circumference of the connecting portion 51, and the first groove segment 321 and the third groove segment 323 are arranged at intervals along the third direction Z, that is, there is a distance between the first groove segment 321 and the third groove segment 323 of the limiting groove 32 in the third direction Z, and there is also a distance in the circumferential direction of the connecting portion 51. It should be noted that, since the first groove segment 321 and the third groove segment 323 are arranged at intervals in the third direction Z and in the circumferential direction of the connecting portion 51, the second groove segment 322 connecting the first groove segment 321 and the third groove segment 323 is a spiral structure surrounding the connecting portion 51, so that when the limiting protrusion 512 is located in the first groove segment 321 and the third groove segment 323, the connecting portion 51 can only move along the third direction Z under the drive of the second gear 62, and when the limiting protrusion 512 is located in the second groove segment 322, the connecting portion 51 can be driven by the second gear 62 to move along the third direction Z and rotate around the axis extending along the third direction Z.

[0177] When the locking member 50 is in the first position, the limiting protrusion 512 is located in the first groove section 321, and when the locking member 50 is in the second position, the limiting protrusion 512 is located in the third groove section 323. That is to say, when the limiting protrusion 512 of the connecting portion 51 moves from the first groove section 321 to the third groove section 323, the locking member 50 can move from the first position to the second position.

[0178] Of course, the structure of the limiting groove 32 is not limited to this. In some embodiments, the limiting groove 32 can also be other structures. For example, the limiting groove 32 is a structure extending along the third direction Z and having a wider width in the circumferential direction of the connecting portion 51, so that the limiting groove 32 has two opposite groove side surfaces in the circumferential direction of the connecting portion 51, and the two groove side surfaces of the limiting groove 32 are arranged at intervals in the circumferential direction of the connecting portion 51, and the two groove side surfaces of the limiting groove 32 are used for the limiting protrusion 512 to abut, and the limiting protrusion 512 is inserted in the limiting groove 32, and The limiting protrusion 512 can move between the two groove side surfaces along the circumference of the connecting part 51 to limit the rotation angle of the connecting part 51, and when the limiting protrusion 512 abuts against the groove side surface of the limiting groove 32, the groove side surface of the limiting groove 32 can block the rotation of the connecting part 51 to limit the rotation angle of the connecting part 51, and the limiting protrusion 512 of the connecting part 51 can move along the third direction Z under the guidance of the groove side surface of the limiting groove 32 after being blocked by the groove side surface of the limiting groove 32, so that the connecting part 51 can move along the third direction Z.

[0179] In this embodiment, the first groove section 321 and the third groove section 323 of the limiting groove 32 are set to structures extending along the third direction Z, and the first groove section 321 and the third groove section 323 are arranged at intervals in the third direction Z and the circumferential direction of the connecting portion 51, so that the second groove section 322 connected between the first groove section 321 and the third groove section 323 is a spirally extended structure, so that when the limiting protrusion 512 of the connecting portion 51 is located in the first groove section 321 and the third groove section 323, it can only move along the third direction Z following the extension direction of the first groove section 321 and the second groove section 322, and when the protrusion of the connecting portion 51 is located in the second groove section 322, it can rotate relative to the lock sleeve 30 following the extension direction of the second groove section 322 and can also move relative to the lock sleeve 30 along the third direction Z, thereby achieving the limitation of the rotation angle of the locking member 50 and enabling it to move between the first position and the second position along the third direction Z. In addition, by setting the third groove section 323 to be closer to the clamping portion 52 in the third direction Z than the first groove section 321, when the protrusion is located in the first groove section 321, the clamping portion 52 can be clamped with the lock seat 300 and can be closer to the lock sleeve 30, so that the clamping portion 52 can abut against each other in the third direction Z with the lock seat 300.
