[0046] The term "plurality" used in the present application refers to two or more (including two).

[0047] 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.

Electric commercial vehicles, such as electric heavy trucks and electric light trucks, are gradually appearing in various application scenarios, and battery replacement stations for electric trucks are also built.

[0059] In the field of new energy vehicles, electric trucks consume more energy than ordinary passenger cars due to their heavy load and long mileage. Therefore, in order to achieve endurance, electric trucks are usually equipped with multiple batteries, and electric trucks need to frequently replace batteries. In the battery replacement process, the locking and separation of the battery installed on the vehicle is the focus of attention. In order to achieve the locking and fixing of the battery, the main method currently used is to set a lock seat on the vehicle and set a locking mechanism on the battery accordingly, and lock or unlock the lock mechanism and the lock seat to complete the vehicle's battery replacement 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 structures, 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 a corresponding operating space, which results in 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.

Along the first direction, the projection of the first fixing portion does not overlap with the projection of the second fixing portion.

[0061] In a battery of this structure, a first surface and a second surface are respectively formed on both sides of the battery box 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 the battery can be assembled to the target part after the first fixing portion and the second fixing portion are locked with the target part through the locking mechanism, so as to improve 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 as a non-overlapping structure, so that the first fixing portion and the second fixing portion are staggered in the first direction, so that 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 as a structure 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 along the first direction, so as to save the space occupied by the multiple batteries in the first direction, which is beneficial to improving the space utilization rate of the batteries.

[0070] In the battery 100, the battery cell 20 disposed in the housing 10 may be one or more. When there are more than one battery cell 20 disposed in the housing 10, the multiple battery cells 20 may be connected in series, in parallel, or in mixed connection. Mixed connection means that the multiple battery cells 20 are both connected in series and in parallel. The multiple battery cells 20 may be directly connected in series, in parallel, or in 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 connecting multiple battery cells 20 in series, in parallel, or in mixed connection, and then the multiple battery modules may be connected in series, in parallel, or in mixed connection to form a whole, and 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.

[0071] Each battery cell 20 may be a secondary battery or a primary battery; it may also be a lithium-sulfur battery, a sodium-ion battery or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular or in other shapes. Figure 6 In the figure, the battery cell 20 is a rectangular parallelepiped structure.

[0072] According to some embodiments of the present application, referring to Figure 3 , Figure 4 , Figure 5 and Figure 6 , and please refer to Figure 7 , Figure 7 A top view of a battery 100 provided in some embodiments of the present application. The present application provides a battery 100, which includes a box 10, which is used to accommodate a battery cell 20, and the box 10 is formed with a first surface 111 and a second surface 112 on both sides of the first direction X, respectively, and 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, and the first fixing portion 113 and the second fixing portion 114 are both used to install a locking mechanism 400, and the locking mechanism 400 is used to lock the box 10 to the target part. Along the first direction X, the projection of the first fixing portion 113 does not overlap with the projection of the second fixing portion 114.

[0073] 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 , and the structure of the box body 10 may be various.

[0074] In some embodiments, Figure 6In the embodiment, 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 the box body 11 and the box cover 12 jointly define an assembly space for accommodating the battery cell 20. The box body 11 and the box cover 12 may be hollow structures each 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 jointly define an assembly space.

[0075] Of course, the structure of the box body 10 is not limited to this, and the box body 10 can also be 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 11 and the box cover 12 can also form a variety of shapes of the box body 10, such as a cylinder, a cuboid, etc. For example, in Figure 5 and Figure 6 In the embodiment, the box body 11 is in the shape of a rectangular parallelepiped.

[0076] The box body 10 has a first surface 111 and a second surface 112 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.

[0077] 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 provided on the surfaces of both sides of the box body 10 in the first direction X. For example, Figure 5 and Figure 6 In the embodiment, the first fixing portion 113 and the second fixing portion 114 are both arranged 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, respectively, wherein the first fixing portion 113 and the second fixing portion 114 are both used to install the locking mechanism 400, that is, in the embodiment in which 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, respectively, that is, in the embodiment in which 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.

[0078] 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, Figure 2 In the figure, the locking mechanism 400 is used to lock or unlock the lock seat 300 on the mounting frame 200 of the vehicle 1000, that is, the target part is the lock seat 300 set on the mounting frame 200 of the vehicle 1000, and the first fixing part 113 and the second fixing part 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.

[0079] Along the first direction X, the projection of the first fixing portion 113 does not overlap with the projection of the second fixing portion 114, that is, the first fixing portion 113 and the second fixing portion 114 are mutually staggered 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, see Figure 4 As shown, 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, and the second direction Y is perpendicular to the first direction X.

[0080] Optionally, in Figure 3 and Figure 4 In the embodiment, the surfaces of the first fixing portion 113 on both sides in the third direction Z are respectively flush with the surfaces of the second fixing portion 114 on both sides 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 Figure 5 and Figure 6 In the figure, 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, 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.

[0081] In the present 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, so as to improve the stability of the battery 100 assembled to the target part, wherein 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 are set to be non-overlapping The structure is such that the first fixing portion 113 and the second fixing portion 114 are staggered in the first direction X, so that 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 as a structure 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, so as to save the space occupied by the multiple batteries 100 in the first direction X, which is conducive to improving the space utilization of the battery 100.

[0082] According to some embodiments of the present application, see Figure 4 , Figure 5 and Figure 6 As shown, the first surface 111 is protruding with a plurality of first fixing portions 113, 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, and the first accommodating gap 115 is used to accommodate at least one second fixing portion 114 of another battery 100, and the second direction Y is perpendicular to the first direction X.

[0083] 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 every 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 two adjacent first fixing portions 113.

[0084] For example, in Figure 4In the embodiment, 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 can also be for inserting two, three or four second fixing portions 114 of another battery 100.

[0085] 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 a second fixing portion 114 of another battery 100 is formed between two adjacent first fixing portions 113, so that when the plurality of batteries 100 are arranged along the first direction X, the second fixing portion 114 of one battery 100 can be inserted into the first accommodating gap 115 of another battery 100, thereby saving the space occupied by the plurality of batteries 100 in the first direction X and increasing the number of first fixing portions 113 on the case 10 for installing the locking mechanism 400, so as to enhance the firmness of the battery 100 locked to the target part, thereby achieving both improving the space utilization of the battery 100 and enhancing the stability and reliability of the battery 100 when assembled to the target part.

[0086] According to some embodiments of this application, please continue to refer to Figure 4 , Figure 5 and Figure 6 As shown, 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 , and the second accommodating gap 116 is used to accommodate at least one first fixing portion 113 of another battery 100 .

[0087] 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 every 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 two adjacent second fixing portions 114.

[0088] For example, in Figure 4 In the embodiment, 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.

[0089] 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, so that when the plurality of batteries 100 are arranged along the first direction X, the first fixing portion 113 of one battery 100 can be inserted into the second accommodating gap 116 of another battery 100, thereby saving the space occupied by the plurality of batteries 100 in the first direction X, and further increasing the number of the second fixing portions 114 on the case 10 for installing the locking mechanism 400, so as to further enhance the firmness of the battery 100 locked to the target part, thereby achieving both an improvement in the space utilization of the battery 100 and further enhancing the stability and reliability of the battery 100 assembled to the target part.

[0090] In some embodiments, see Figure 3 , Figure 4 and Figure 7 As shown, the first fixing portion 113 and the second fixing portion 114 are arranged alternately in sequence along the second direction Y. That is, after the plurality of batteries 100 are arranged along the first direction X and the second fixing portion 114 is inserted into the first accommodation gap 115, the first fixing portion 113 of one battery 100 and the second fixing portion 114 of another battery 100 are arranged alternately in sequence along the second direction Y.

[0091] Among them, in the embodiment where 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 every 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 every two adjacent second fixing portions 114 in the second direction Y.

[0092] 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 alternately arranged 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 is convenient for arranging multiple batteries 100 along the first direction X, which is helpful to reduce 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, so as to improve the stability and stability of the battery 100 locked on the target part through the locking mechanism 400.

[0093] According to some embodiments of the present application, see Figure 7As shown, 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. That is, 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.

[0094] 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 excessive size of the first fixing portion 113 protruding from the first surface 111 or the excessive size of the second fixing portion 114 protruding from the second surface 112, thereby further reducing the gap between the multiple batteries 100, so as to further improve the space utilization of the battery 100.

[0095] In some embodiments, see Figure 4 and Figure 7 As shown, the first fixing portion 113 is in a rectangular parallelepiped shape. Of course, in other embodiments, the shape of the first fixing portion 113 may also be cylindrical or polygonal.

[0096] 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 beneficial to reduce the difficulty of setting the first fixing portion 113 on the first surface 111; on the other hand, the regularity of the shape of the first fixing portion 113 can be improved, so as to reduce the difficulty of the first fixing portion 113 avoiding the second fixing portion 114, and facilitate the arrangement of multiple batteries 100 along the first direction X.

[0097] In some embodiments, see Figure 5 and Figure 7 As shown, the second fixing portion 114 is in a rectangular parallelepiped shape. Of course, in other embodiments, the shape of the second fixing portion 114 may also be cylindrical or polygonal.

[0098] 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 beneficial to reduce the difficulty of setting the second fixing portion 114 on the second surface 112; on the other hand, the regularity of the shape of the second fixing portion 114 can be improved to reduce the difficulty of the second fixing portion 114 avoiding the first fixing portion 113, and it is convenient to arrange multiple batteries 100 along the first direction X.

[0099] According to some embodiments of the present application, see Figure 5 and Figure 6 As shown, the box body 10 may include a box body 11 and a box cover 12. The box body 11 has an accommodation space with an opening 117 formed inside, and the accommodation space is used to accommodate the battery cell 20. The box cover 12 covers the opening 117. Along the first direction X, the two sides of the box body 11 respectively form a first surface 111 and a second surface 112.

[0100] In which, along the first direction X, two sides of the box body 11 respectively form a first surface 111 and a second surface 112 , that is, the first fixing portion 113 and the second fixing portion 114 are respectively protruded on the surfaces of the two sides of the box body 11 in the first direction X.

[0101] In the present 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 realize the assembly and accommodation of the battery cell 20. The box body 11 forms a first surface 111 and a second surface 112 on both sides of 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 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 bear the box body 11, which is beneficial to improve the 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.

[0102] According to some embodiments of the present application, the present application also provides an electrical device, comprising a battery 100 according to any of the above solutions.

[0103] The power-consuming device may be any of the aforementioned devices or systems using the battery 100 .

[0104] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device in an embodiment of the present application. Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, a plurality of batteries 100 are arranged along a first direction X. In two adjacent batteries 100, a first surface 111 of one battery 100 and a second surface 112 of the other battery 100 are arranged facing each other, and a first fixing portion 113 of one battery 100 and a second fixing portion 114 of the other battery 100 are arranged along a second direction Y, and the second direction Y is perpendicular to the first direction X.

[0105] 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 surface 111 and the second surface 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 where the first surface 111 and the second surface 112 face each other.

[0106] The first fixing portion 113 of one battery 100 and the second fixing portion 114 of another 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.

[0107] In the present embodiment, the electrical device is provided with a plurality of batteries 100, and the plurality of batteries 100 are arranged along a first direction X, and 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, so 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, so that the plurality of batteries 100 can share part of the space in the first direction X, so as to reduce the overall size of the plurality of batteries 100 arranged along the first direction X, thereby saving the space occupied by the plurality of batteries 100 on the electrical device, which is beneficial to improving the space utilization rate of the plurality of batteries 100.

[0108] In some embodiments, see Figure 4 and Figure 7 As shown, 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, 1.1L3≤L1≤1.6L3.

[0109] For example, in Figure 4 and Figure 7 In the embodiment, 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 .

[0110] 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 .

[0111] 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 from the first surface 111, the phenomenon that the assembly space between the first surface 111 of one battery 100 and the second surface 112 of the other battery 100 is too small 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, and 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 first fixing portion 113 protruding on the first surface 111, the phenomenon of excessive reserved assembly gap between the first surface 111 of one battery 100 and the second surface 112 of another battery 100 can be alleviated, 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 battery 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 that the assembly space between the first surface 111 of one battery 100 and the second surface 112 of another battery 100 is too small can be alleviated, thereby reducing the interference and scratching between the second fixing portion 114 of one battery 100 and the first surface 111 of another battery 100, which is conducive to reducing the difficulty of assembling multiple batteries 100 in sequence along the first direction X, and 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 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 can be alleviated, thereby saving the space occupied by multiple batteries 100 in the first direction X, which is conducive to further improving the space utilization of the battery 100.

[0112] According to some embodiments of the present application, see Figure 2 , Figure 3 and Figure 4As shown, 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 which 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, and the third direction Z is perpendicular to the first direction X and the second direction Y.

[0113] Among them, the vehicle 1000 has a mounting frame 200, the target part is a 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.

[0114] Optionally, the lock base 300 and the mounting frame 200 may be an integrated structure or a split structure. When the lock base 300 and the mounting frame 200 are an integrated structure, that is, the lock base 300 is a part of the mounting frame 200, that is, the target part is also the mounting frame 200; when the lock base 300 and the mounting frame 200 are a split structure, the lock base 300 may be connected to the mounting frame 200 by welding, bolting, or clamping.

[0115] 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 .

[0116] 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 to say, 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 interconnected with 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.

[0117] 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.

[0118] In this embodiment, the locking mechanism 400 of the electrical device is a structure that connects the first fixing portion 113 of one of the two adjacent batteries 100 and the second fixing portion 114 of the other battery 100, so that the first fixing portion 113 and the second fixing portion 114 of the two adjacent batteries 100 share a locking mechanism 400, and are mutually locked with the target part through the locking mechanism 400. The electrical device using this structure can simultaneously realize the locking or unlocking of 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, so as to realize 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.

[0119] According to some embodiments of the present application, referring to Figure 3 and Figure 4 , and please refer to Figure 8 , Fig. 9 and Fig.10 , Figure 8 This is a schematic diagram of the structure of the locking mechanism 400 provided in some embodiments of the present application. Fig. 9 This is an exploded view of the locking mechanism 400 provided in some embodiments of the present application. Fig.10A cross-sectional view of a locking mechanism 400 provided in some embodiments of the present application. The locking mechanism 400 may include a locking sleeve 30, an adjusting member 40, and two locking members 50. Along the first direction X, 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. Along the first direction X, in two adjacent batteries 100, the two locking members 50 are respectively penetrated through the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100, and both locking members 50 can be movably arranged on the locking sleeve 30. The locking member 50 has a locked state and an unlocked state. The locking member 50 is configured to be engaged with the target member when in the locked state, so that the locking mechanism 400 is engaged with the target member along the third direction Z. The locking member 50 is configured to be released from the target member when in the unlocked state, so as to allow the locking mechanism 400 to be disengaged from the target member along the third direction Z. The adjusting member 40 is disposed on the locking sleeve 30 , and is configured to drive the two locking members 50 to move relative to the locking sleeve 30 , so that the locking members 50 are switched between a locked state and an unlocked state.

[0120] The lock sleeve 30 serves to connect two batteries 100 adjacent to each other in the first direction X, and serves to assemble the adjusting member 40 and the locking member 50, so that the locking mechanism 400 can lock the battery 100 on the lock seat 300 through the locking member 50. The lock sleeve 30 is a hollow structure, so that the adjusting member 40 and the locking member 50 can be assembled.

[0121] Exemplarily, the lock sleeve 30 may be made of various materials, such as steel, aluminum, iron, aluminum alloy or plastic.

[0122] 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. Figure 3 and Figure 4 In the embodiment, when 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 another battery 100 are arranged along the second direction Y, the locking sleeve 30 of the locking mechanism 400 can be connected to the first fixing portion 113 and the second fixing portion 114 adjacent to each other in the second direction Y.

[0123] In two adjacent batteries 100, two locking members 50 are respectively provided through the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100, that is, the two locking members 50 of the locking mechanism 400 are respectively provided through the first fixing portion 113 of one battery 100 and the second fixing portion 114 of the other battery 100, so as to lock the two adjacent batteries 100 on the lock seat 300. Among them, one locking member 50 of the locking mechanism 400 passes through the upper surface of the first fixing portion 113 of one battery 100 along the third direction Z, and the other locking member 50 passes through the upper surface of the second fixing portion 114 of the other battery 100 along the third direction Z.

[0124] 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.

[0125] The locking member 50 can move relative to the lock sleeve 30, so that the locking member 50 has a locked state in which it can be engaged with the lock seat 300 and an unlocked state in which it can be released from the lock seat 300. Fig. 9 and Fig.10 In the embodiment, the locking member 50 includes a connecting portion 51 and a clamping portion 52 connected to each other. 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 adjusting member 40. The clamping portion 52 is connected to one end of the connecting portion 51 extending out of the lock sleeve 30 in the third direction Z. The clamping portion 52 plays a role of mutually clamping with the lock seat 300. The extending direction of the clamping portion 52 is perpendicular to the third direction Z, so that the locking member 50 is an irregular structure that can rotate around the axis extending in the third direction Z, so that the clamping portion 52 can be driven to rotate by rotating the connecting portion 51, so that the clamping portion 52 can be clamped or released with the lock seat 300. Of course, in other embodiments, the clamping portion 52 of the locking member 50 can also be a structure that is retractable in a direction perpendicular to the third direction Z, so that the locking member 50 can be clamped or released with the lock seat 300 through the clamping portion 52.

[0126] The adjusting member 40 is configured to drive the two locking members 50 to move relative to the locking 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 locking sleeve 30, so that the locking members 50 switch between the locked state and the unlocked state. Fig. 9 and Fig.10In the embodiment, the adjusting member 40 can drive the connecting portion 51 of the locking member 50 to rotate relative to the locking sleeve 30, so that the connecting portion 51 drives the clamping portion 52 to rotate, thereby realizing that the clamping portion 52 whose extension direction is perpendicular to the third direction Z rotates in a plane perpendicular to the third direction Z, and then the clamping portion 52 can be clamped or released from the lock seat 300, so as to realize the switching of the locking member 50 between the locked state and the unlocked state.

[0127] It should be noted that the adjusting member 40 is configured to be able to drive the two locking members 50 to move relative to the locking sleeve 30. The adjusting member 40 can individually drive each locking member 50 to move relative to the locking sleeve 30, that is, the adjusting member 40 can individually drive each locking member 50 to switch between the locked state and the unlocked state in a sequence. In other words, the adjusting member 40 is selectively transmission-connected to one of the two locking members 50, so that the adjusting member 40 can drive different locking members 50 to move relative to the locking sleeve 30 in a sequence, thereby driving different locking members 50 to switch between the locked state and the unlocked state in turn through the adjusting member 40. Of course, the adjusting member 40 can also simultaneously drive the two locking members 50 to move relative to the locking sleeve 30, that is, the adjusting member 40 can simultaneously drive the two locking members 50 to switch between the locked state and the unlocked state.

[0128] For example, in Fig. 9 and Fig.10 In the embodiment, 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 a structure that is 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.

[0129] 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 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 penetrated through 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 two adjacent batteries 100 are locked with the target member, so that the stability of the mutual locking between the battery 100 and the target member is improved, and the two locking members 50 can 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.

[0130] According to some embodiments of the present application, see Fig. 9 and Fig.10 As shown, the locking mechanism 400 may further include a transmission assembly 60. The transmission assembly 60 is disposed in the lock sleeve 30, and the two locking members 50 are selectively connected to the adjusting member 40 through the transmission assembly 60. The adjusting member 40 is rotatably disposed on the lock sleeve 30 around an axis extending along the third direction Z. The adjusting member 40 is configured to be able to individually drive each locking member 50 to move relative to the lock sleeve 30 when rotating relative to the lock sleeve 30, so that the locking member 50 switches between a locked state and an unlocked state.

[0131] The transmission assembly 60 plays a role in transmission connection between 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 .

[0132] 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 .

[0133] The adjusting member 40 is rotatably disposed on the lock sleeve 30 around an axis extending along the third direction Z. The adjusting member 40 is configured to be able to individually drive each locking member 50 to move relative to the lock sleeve 30 when rotating relative to the lock sleeve 30, so that the locking member 50 switches between the locked state and the unlocked state. That is, the adjusting member 40 can rotate relative to the lock sleeve 30 around an axis extending along the third direction Z, so that the corresponding locking member 50 can be driven to move relative to the lock sleeve 30 through the transmission assembly 60 by rotating the adjusting member 40, thereby realizing the switching of the locking member 50 between the locked state and the 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 realize the movement of the locking member 50 relative to the lock sleeve 30.

[0134] Among them, Fig.10 In the embodiment, 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.

[0135] 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 as to enable the adjusting member 40 to individually drive the single locking member 50 to switch between the locked state and the unlocked state.

[0136] According to some embodiments of this application, please continue to refer to Fig. 9 and Fig.10 As shown, the transmission assembly 60 may include a first gear 61 and two second gears 62. The first gear 61 is fixedly sleeved on the outer side of the adjustment member 40. The two second gears 62 are selectively meshed 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 meshed with the second gear 62, so as to drive the corresponding locking member 50 to move relative to the lock sleeve 30, so that the locking member 50 switches between the locked state and the unlocked state.

[0137] Among them, the first gear 61 is fixedly sleeved on the outside of the adjusting member 40, that is, the first gear 61 is a structure sleeved on the outside of the adjusting member 40, and the first gear 61 is fixedly connected to the adjusting member 40, so that the first gear 61 and the adjusting member 40 are circumferentially locked and axially locked along the third direction Z.

[0138] Exemplarily, 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, bonding or other structures.

[0139] The two second gears 62 are selectively meshed with the first gear 61, that is, the first gear 61 sleeved 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 sleeved on the adjusting member 40 can selectively mesh with the second gears 62 connected to different locking members 50.

[0140] The adjusting member 40 is configured to drive the corresponding second gear 62 to rotate when the first gear 61 is meshed with the second gear 62, so as to drive the corresponding locking member 50 to move relative to the locking sleeve 30. That is to say, when the first gear 61 mounted on the adjusting member 40 is meshed 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.

[0141] It should be noted that there may be various structures in which the two second gears 62 selectively mesh 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 mesh with the first gear 61, the two second gears 62 may selectively mesh with the first gear 61. For example, the second gear 62 may be 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 may selectively mesh with one of the two second gears 62.

[0142] 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, 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, and the structure is simple and easy to implement.

[0143] In some embodiments, see Fig.10 As shown, the adjusting member 40 is movably disposed on the locking sleeve 30 along the third direction Z. The adjusting member 40 is configured to move along the third direction Z to drive the first gear 61 to selectively mesh with one of the two second gears 62 .

[0144] The adjusting member 40 is movably disposed on the lock sleeve 30 along the third direction Z. By moving the adjusting member 40 along the third direction Z, the first gear 61 sleeved on the outer side of the adjusting member 40 can be driven to move along the third direction Z, so that the first gear 61 can be meshed with different second gears 62 of the two second gears 62 in sequence. In other words, the two second gears 62 are staggered in the third direction Z, so that the first gear 61 can be meshed with different second gears 62 when moving along the third direction Z.

[0145] Alternatively, see Fig. 9 and Fig.10 As shown, 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, the toothed portion 622 is fixedly sleeved on the outer side of the main body 621, 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 mesh 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.

[0146] Among them, the toothed portions 622 of the two second gears 62 are structures arranged at intervals along the third direction Z, so that the first gear 61 can engage with the toothed 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.

[0147] Exemplarily, the main body 621 and the locking member 50 are threadedly connected structures, and the main body 621 of the second gear 62 is sleeved on the outer side 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 clamp or release 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.

[0148] It should be noted that, in other embodiments, the toothed portions 622 of the plurality of second gears 62 may be structures 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 simultaneously meshes with the toothed portions 622 of the two second gears 62. The locking mechanism 400 adopting such a 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.

[0149] In this embodiment, by setting the adjustment member 40 as a structure that is movably arranged in the lock sleeve 30 along the third direction Z, the adjustment 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 the first gear 61 mounted on the adjustment member 40 can selectively engage with one of the two second gears 62, the structure is simple, and it is easy to assemble.

[0150] According to some embodiments of the present application, see Figure 8 , Fig. 9 and Fig.10 As shown, 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 one end of the connecting portion 51 away from the lock sleeve 30. The clamping portion 52 protrudes from the outer peripheral surface of the connecting portion 51 along its extension direction. The clamping portion 52 is used to clamp with the lock seat 300. The extension direction of the clamping portion 52 is perpendicular to the third direction Z. The second gear 62 is configured to drive the corresponding connecting portion 51 of the locking member 50 to rotate when rotating relative to the lock sleeve 30, so that the clamping portion 52 is clamped or released with the lock seat 300, so that the locking member 50 switches between the locked state and the unlocked state.

[0151] The connecting portion 51 of the locking member 50 is a cylindrical structure extending along the third direction Z, and a portion of the connecting portion 51 is inserted into the lock sleeve 30 along the third direction Z, and one end of the connecting portion 51 extending out of the lock sleeve 30 is connected to the clamping portion 52. One end of the connecting portion 51 away from the clamping portion 52 in the third direction Z is connected to the main body 621 of the second gear 62, and the main body 621 of the second gear 62 is screwed to the outer side of the clamping portion 52, that is, the portion of the connecting portion 51 inserted into the main body 621 of the first gear 61 is provided with an external thread, and correspondingly, the main body 621 of the first gear 61 is provided with an internal thread, so that the main body 621 of the second gear 62 can be screwed to the outer side of the clamping portion 52. Of course, in other embodiments, the connecting portion 51 may be threadedly connected to the outer side 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 threadedly connected to the outer side of the main body 621.

[0152] 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.

[0153] The clamping portion 52 protrudes from the outer peripheral surface of the connecting portion 51 along its extending direction, that is, in the extending direction of the clamping portion 52, the clamping portion 52 extends from the outer peripheral surface of the connecting portion 51. Fig.10 In the embodiment, the extending 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.

[0154] For example, in Fig. 9 and Fig.10 In the figure, 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.

[0155] The second gear 62 is configured to be able 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 seat 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 meshing 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 then the extension direction of the clamping portion 52 can be changed, so that the clamping portion 52 can overlap the lock seat 300 or release the overlap from the lock seat 300, so that the clamping portion 52 can be clamped or released from the lock seat 300.

[0156] In some embodiments, reference Fig. 9 and Fig.10 , and please refer to Fig.11 , Fig.11 The following is a schematic diagram of the assembly of the lock base 300 and the locking member 50 of the locking mechanism 400 that are mutually locked with each other in some embodiments of the present application. The lock base 300 is provided with a lock hole 301 for the locking member 50 to be inserted, and the lock hole 301 penetrates 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 clamping portion 52 of the locking member 50 to rotate around the axis extending along the third direction Z through the transmission assembly 60, so that the clamping portion 52 can be engaged 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 are engaged in the third direction Z, thereby realizing the mutual locking between the locking mechanism 400 and the lock base 300, so as to achieve the locking of the locking mechanism 400 and the lock base 300. The two batteries 100 adjacent to each other in the first direction X are locked on the lock seat 300 of the mounting frame 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.

[0157] Among them, the cross-section of the locking 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 locking hole 301, the clamping portion 52 can be inserted into the locking hole 301 or can be withdrawn from the locking hole 301. When the clamping portion 52 passes through the locking hole 301 and the extension direction of the clamping portion 52 intersects with the length direction of the cross-section of the locking hole 301, the clamping portion 52 can be engaged on the surface of the lock seat 300 on the side facing away from the lock sleeve 30.

[0158] Optionally, a card slot 302 is further provided on the surface of the lock seat 300 for the engaging portion 52, and the extending direction of the card slot 302 is perpendicular to the length direction of the cross section of the lock hole 301. When the card slot 52 is rotated to the point where the extending direction is perpendicular to the length direction of the cross section of the lock hole 301, the card slot 302 can engage with the lock seat 300, and the card slot 302 can be inserted into the card slot 302 to alleviate the shaking phenomenon between the locking mechanism 400 and the lock seat 300, which is beneficial to improve the stability of the mutual locking of the locking mechanism 400 and the lock seat 300.

[0159] In this embodiment, 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 with the second gear 62, the adjusting member 40 can drive the corresponding second gear 62 to rotate when the first gear 61 and the second gear 62 are meshed, so as to drive the corresponding connecting portion 51 of the 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.

[0160] According to some embodiments of the present application, referring to Fig. 9 and Fig.10 , and please refer to Fig.12 , Fig.12 The lock sleeve 30 of the locking mechanism 400 provided in some embodiments of the present application is a cross-sectional view. The lock 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.

[0161] 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 arranged on the inner circumference of the locking sleeve 30, and correspondingly, the second limiting portion 511 can be a limiting protrusion 512 convexly arranged 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. 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 locking 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. When the connecting portion 51 rotates relative to the locking sleeve 30, the second limiting portion 511 can abut against the first limiting portion 31, so as to limit the rotation angle of the connecting portion 51 through the mutual cooperation between the first limiting portion 31 and the second limiting portion 511.

[0162] Optionally, the number of the first limiting portion 31 and the second limiting portion 511 provided between each locking member 50 and the locking sleeve 30 may be one or more. Fig. 9 and Fig.10 In the figure, 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.

[0163] 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 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 can be alleviated, which is beneficial to improving the reliability of the mutual locking between the locking mechanism 400 and the lock seat 300.

[0164] According to some embodiments of the present application, see Fig. 9 , Fig.10 and Fig.11As shown, the connecting portion 51 is screwed 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 located at the first position, the locking member 50 is in a locked state, so that the clamping portion 52 can be clamped with the lock seat 300; when the locking member 50 is located at the second position, the locking member 50 is in an unlocked state, so that the clamping portion 52 can be released from the lock seat 300.

[0165] 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, when the adjusting member 40 drives the corresponding connecting portion 51 to rotate relative to the locking 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 and can also guide the connecting portion 51 to move relative to the locking sleeve 30 in the third direction Z, so that the locking member 50 has two end positions relative to the locking sleeve 30 in the third direction Z, namely the first position and the second position. The locking member 50 is in the first position when the locking member 50 is in the second position, that is, when the adjusting member 40 drives the corresponding connecting portion 51 to rotate relative to the locking sleeve 30 through the transmission assembly 60, the connecting portion 51 can also move relative to the locking 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 locking sleeve 30, the locking member 50 is in the first position, and 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 be disengaged from the lock seat 300 along the third direction Z.

[0166] When the adjusting member 40 rotates relative to the locking sleeve 30, the transmission assembly 60 can drive the connecting portion 51 to rotate and also drive the connecting portion 51 to move along the third direction Z. For example, Fig.10 In the figure, there is a threaded connection structure between the main body 621 of the second gear 62 of the transmission assembly 60 and the connecting part 51, so that the adjustment 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 as to enable the connecting part 51 to move along the third direction Z.

[0167] In this embodiment, by setting the connecting part 51 and the second gear 62 as a structure in which the connecting part 51 is threadedly connected to each other, the locking mechanism 400 adopting such a structure enables the second gear 62 to apply a feeding 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 cooperate to guide the connecting part 51 to move relative to the locking sleeve 30 in the third direction Z while limiting the rotation angle of the connecting part 51, so that the adjusting member 40 can drive the connecting part 51 to rotate relative to the locking sleeve 30 through the first gear 61 and the second gear 62, and can also drive the locking member 50 to move between the first position and the second position along the third direction Z, so that the adjusting member 40 can drive the clamping part 52 to clamp with the lock seat 300 while driving the clamping part 52 and the lock seat 300 to abut against each other, so as to reduce the gap between the clamping part 52 and the lock seat 300, which is beneficial to reduce the vibration or impact between the locking mechanism 400 and the lock seat 300.

[0168] According to some embodiments of this application, see Fig. 9 , Fig.10 and Fig.12 As shown, the first limiting portion 31 is a limiting groove 32 arranged on the inner circumference of the locking sleeve 30 , and the second limiting portion 511 is a limiting protrusion 512 protruding on the outer circumference of the connecting portion 51 , and at least a portion of the limiting protrusion 512 is accommodated in the limiting groove 32 .

[0169] 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.

[0170] For example, in Fig. 9 and Fig.11 In the embodiment, the limiting groove 32 arranged on the lock sleeve 30 passes through the outer circumferential surface of the lock sleeve 30, so as to facilitate the processing and formation of the limiting groove 32 on the inner circumferential 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.

[0171] In this embodiment, the first limiting portion 31 and the second limiting portion 511 are respectively arranged on the limiting groove 32 on the inner circumferential surface of the locking sleeve 30 and the 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 along the third direction Z relative to the locking sleeve 30. The structure is simple, easy to implement, and has high stability.

[0172] In some embodiments, please see Fig. 9 , Fig.10 and Fig.12 As shown, 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 arranged at intervals along the circumference of the connecting portion 51, and the first groove section 321 and the third groove section 323 are arranged at intervals along the third direction Z, and along the third direction Z, the third groove section 323 is closer to the clamping portion 52 than the first groove section 321. When the locking member 50 is located at the first position, the limiting protrusion 512 is located in the first groove section 321, and when the locking member 50 is located at the second position, the limiting protrusion 512 is located in the third groove section 323.

[0173] 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 move along the third direction Z and rotate around the axis extending along the third direction Z under the drive of the second gear 62.

[0174] When the locking member 50 is located at the first position, the limiting protrusion 512 is located in the first groove section 321, and when the locking member 50 is located at 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.

[0175] Of course, the structure of the limiting groove 32 is not limited to this. In some embodiments, the limiting groove 32 may 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.

[0176] In this embodiment, the first groove section 321 and the third groove section 323 of the limiting groove 32 are arranged to be 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 follow the extension direction of the second groove section 322 to rotate relative to the lock sleeve 30 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 being able 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 the lock seat 300 in the third direction Z.
