Description

Technical Field

[0001] The embodiments of the present application relate to the field of battery technology, and in particular to an output pole base, a battery, and an electrical device. Background Art

[0002] The battery includes multiple components, including multiple battery cells, end plates, an output pole base, and an output pole connecting plate. The end plates are located at both ends of the battery cells along their stacking direction and are used to limit the position of the battery cells. The output pole connecting plate is used to electrically connect the battery to an external device. The output pole base is fixed to the end plate and is used to secure the output pole connecting plate. A vehicle equipped with a battery will vibrate during driving. To prevent the output pole base from falling off the end plate during vibration, the output base needs to be fixed to a certain position on the end plate.

[0003] The output pole base in the related art can only be used to fix a single specification of output pole connecting plate, which makes the output pole base less universal and maintainable. When the output pole base is not suitable, it needs to be removed from the end plate and replaced, which is labor-intensive and difficult. Summary of the Invention

[0004] In view of the above problems, an embodiment of the present application provides an output pole base, a battery and an electrical device. The output pole base can be used to fix output pole connecting pieces of different specifications. It has high universality and high maintainability, and the maintenance workload and difficulty are also low.

[0005] According to a first aspect of an embodiment of the present application, an output pole base is provided, comprising a base body and two limit assemblies. The base body is used to secure an output pole connecting piece and is fixed to an end plate along a first direction. The two limit assemblies are movably connected to opposite ends of the base body along a second direction, the spacing between the two limit assemblies along the second direction being adjustable, and the two limit assemblies are used to limit the position of the output pole connecting piece, wherein the second direction is perpendicular to the first direction.

[0006] Through the above solution, the movable limit assembly can adjust the spacing between the two limit assemblies along the second direction to accommodate output pole connecting pieces of different specifications. Furthermore, if a limit assembly is damaged, it can be easily removed from the base body and replaced, without having to remove the entire output pole base from the end plate for replacement. Therefore, the output pole base provided in the embodiments of the present application can be used to secure output pole connecting pieces of different specifications, with high universality and high maintainability, and low maintenance workload and difficulty.

[0007] In some embodiments, the stopper assembly includes a first connecting plate, a second connecting plate, and a stopper plate. The first connecting plate and the second connecting plate are spaced apart along a first direction, and the stopper plate is configured to connect one end of the first connecting plate and the second connecting plate. A receiving slot is formed between the first connecting plate, the second connecting plate, and the stopper plate, and the end of the base body along the second direction is mounted in the receiving slot.

[0008] Through the above scheme, the end of the base body along the second direction is installed in the accommodating groove, so that the limit assembly can be connected to the end of the base body along the second direction. The connection method is simple and easy, which improves the efficiency of connecting the limit assembly and the base body.

[0009] In some embodiments, one end of the second connecting plate is rotatably connected to the limiting plate.

[0010] With the above solution, the slot size of the receiving slot can be easily adjusted by rotating the second connecting plate, thereby facilitating installation of both ends of the base body along the second direction in the receiving slot, thereby realizing a movable connection between the base body and the limiting assembly.

[0011] In some embodiments, the limiting plate is provided with a fixed shaft, one end of the second connecting plate has a mounting hole, and the fixed shaft is inserted into the mounting hole to rotatably connect the second connecting plate to the limiting plate.

[0012] According to the above solution, the second connecting plate can be rotatably connected to the limiting plate by inserting the fixed shaft into the mounting hole. The connection method is simple and has strong operability.

[0013] In some embodiments, at least one first limiting structure is provided on the surface of the base body at the end portion along the second direction facing the first connecting plate, and at least one second limiting structure is provided on the surface of the first connecting plate facing the base body. The first limiting structure and the second limiting structure cooperate with each other, and the base body and the limiting assembly are movably connected through the first limiting structure and the second limiting structure.

[0014] Through the above solution, the base body and the limiting assembly can be movably connected via the first limiting structure and the second limiting structure. When there are multiple first limiting structures and second limiting structures, adjusting the matching relationship between the multiple first limiting structures and the multiple second limiting structures can adjust the spacing between the two limiting assemblies along the second direction, which is conducive to expanding the application range of the output pole base.

[0015] In some embodiments, one of the first limiting structure and the second limiting structure is a sliding groove, and the other is a sliding rail.

[0016] Through the above scheme, one of the first limiting structure and the second limiting structure can slide along the other, so that the limiting component can be movably connected or disassembled on the base body by sliding. The disassembly and assembly method is simple and easy, which can improve the disassembly and assembly efficiency of the limiting component.

[0017] In some embodiments, the first limiting structure and the second limiting structure are extended along the third direction, or the first limiting structure and the second limiting structure are extended along the second direction, wherein the first direction, the second direction and the third direction are perpendicular to each other.

[0018] Through the above scheme, the limiting assembly can be movably connected to the end of the base body along the second direction along the second direction, or the limiting assembly can be movably connected to the end of the base body along the second direction along the third direction, making the connection between the limiting assembly and the base body more flexible and diverse.

[0019] In some embodiments, the output pole base further includes a clamping plate that protrudes from a side of the base body facing away from the end plate along a first direction and is fixed to an end of the second connecting plate away from the limiting plate to limit the position of the output pole connecting piece.

[0020] In this embodiment, the clamping plate protrudes from the side of the base body facing away from the end plate in the first direction, so that the clamping plate can cooperate with the limit plate to limit the position of the output pole connecting piece in the third direction. When the base body is provided with a clamping plate at both ends in the second direction, and both clamping plates protrude from the side of the base body facing away from the end plate in the first direction, the two clamping plates can limit the position of the output pole connecting piece in the second direction.

[0021] In some embodiments, an elastic portion is provided at the end of the second connecting plate away from the limiting plate, and a clamping groove is provided at a portion of the clamping plate opposite to the elastic portion, and the elastic portion and the clamping groove cooperate with each other.

[0022] Through the above solution, the elastic portion is snapped into the slot to achieve the connection between the snap-in plate and the second connecting plate. The connection method is simple and reliable, and the assembly efficiency of the output pole base can be improved.

[0023] In some embodiments, a positioning column is provided at the end of the second connecting plate away from the limiting plate, and a positioning hole is provided at a portion of the clamping plate opposite to the positioning column, and the positioning column and the positioning hole cooperate with each other.

[0024] This solution provides a positional guide for the assembly of the snap-in plate and the second connecting plate, facilitating quick and accurate insertion of the elastic portion into the slot. Furthermore, when the base body has positioning posts at both ends along the second direction, if the base body shakes or rotates relative to the end plates, the positioning posts can absorb some of the force, effectively reducing the force acting on the elastic portion. This reduces damage to this vulnerable component, thus extending the service life of the output pole base.

[0025] In some embodiments, a clamping portion is provided on a surface of the clamping plate facing the base body, and the clamping portion is clamped on a surface of the first connecting plate facing away from the base body.

[0026] Through the above solution, it is convenient to clamp the end of the base body along the second direction in the accommodating groove, thereby reducing the possibility of the limiting assembly shaking relative to the base body.

[0027] According to a second aspect of an embodiment of the present application, a battery is provided, comprising a plurality of battery cells, an end plate, an output pole connecting piece, and the output pole base of the first aspect. The end plate is used to limit the position of the plurality of battery cells; the output pole base is fixed to the end plate along a first direction; and the output pole connecting piece is fixed to the output pole base.

[0028] According to a third aspect of an embodiment of the present application, there is provided an electrical device comprising the battery according to the second aspect, wherein the battery is configured to provide electrical energy to the electrical device.

[0029] The above description is only an overview of the technical solutions of the embodiments of the present application. In order to more clearly understand the technical means of the embodiments of the present application, they can be implemented in accordance with the contents of the specification.

Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0050] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this application belongs; the terms used in the specification of the application herein are only for the purpose of describing specific embodiments and are not intended to limit this application.

Additionally, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0054] The directional words appearing in the following description are all directions shown in the drawings, and do not limit the specific structure of the output pole base, battery and electrical device of the present application. For example, in the description of the present application, the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like indicate directions or positional relationships based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present application.

Those skilled in the art will understand the specific meanings of the above terms in this application.

[0059] The output terminal connecting piece plays an important role in the battery as a structure that electrically connects the battery to an external device. Currently, in order to fix the output terminal connecting piece, it is necessary to install an output terminal base on the end plate, and then fix the output terminal connecting piece through the output terminal base.

[0060] In related art, the output pole base includes a base body and four stop plates. The four stop plates are fixed to the four corners of the base body and are integrally formed with the base body. To secure the output pole connecting piece, first pass it between two adjacent stop plates. Then, use bolts or other fasteners to secure the output pole connecting piece to the output pole base, and then secure the output pole base to the end plate.

[0061] The inventors discovered that when fixing the output pole connecting piece, torsion is generated, and the limiting plate is a thin-walled structure, which is easily damaged by torsion or other reasons. If the limiting plate is integrally formed with the base body, when the limiting plate is damaged, the output pole base needs to be removed from the end plate as a whole in order to replace the limiting plate, which is very inconvenient. In addition, the integral formation of the limiting plate and the base body means that the output pole base can only be used to fix output pole connecting pieces of a single specification, and its universality and maintainability are relatively low. There are many specifications of output pole connecting pieces. If the output pole base is not applicable, the output pole base also needs to be removed from the end plate as a whole, which is a large workload and difficult to do, and the scope of application of the output pole base is very limited.

[0062] Based on this, an embodiment of the present application provides an output pole base, wherein two limiting assemblies of the output pole base are movably connected to the two ends of the base body along the second direction. By moving the limiting assemblies, the spacing between the two limiting assemblies along the second direction can be adjusted to accommodate output pole connecting pieces of different specifications. Furthermore, when the limiting assemblies are damaged, the limiting assemblies can be conveniently removed from the base body and replaced, without the need to remove the entire output pole base from the end plate and then replace it. Therefore, the output pole base provided in the embodiment of the present application can be used to fix output pole connecting pieces of different specifications, has high universality and high maintainability, and has low maintenance workload and difficulty.

[0063] In some embodiments, as Figures 1 to 3 As shown, an embodiment of the present application provides an output pole base 103, which includes a base body 1 and two limit assemblies 2. The base body 1 is used to fix the output pole connecting piece 102 and is fixed to the end plate 101 along a first direction X. The two limit assemblies 2 are movably connected to the two ends of the base body 1 along a second direction Y. The spacing between the two limit assemblies 2 along the second direction Y is adjustable. The two limit assemblies 2 are used to limit the position of the output pole connecting piece 102. The second direction Y is perpendicular to the first direction X.

[0064] The base body 1 can be made of plastic or a plastic material, and can be an injection-molded plastic part or plastic component to provide insulation and protection for the output pole connecting piece 102. The base body 1 is provided with assembly holes along a first direction X, which are used to cooperate with bolts, pins, and other fixings to secure the output pole connecting piece 102 to the base body 1, and to secure the base body 1 to the end plate 101. It should be noted that the end plates 101 are generally located on both sides of the battery cells 104 along the stacking direction to resist the expansion force of the battery cells 104. The first direction X here can be perpendicular to the stacking direction of the battery cells 104.

[0065] The structures of the two limiting assemblies 2 can be the same. The two limiting assemblies 2 can be symmetrically distributed at both ends of the base body 1 along the second direction Y with respect to the geometric center of the base body 1, or they can be asymmetrically distributed, and this is not limited in the embodiments of the present application. The limiting assembly 2 is movably connected to the base body 1, so the limiting assembly 2 can not only be installed on the base body 1, but also be removed from the base body 1. When the two limiting assemblies 2 are installed on the base body 1, the spacing between the two limiting assemblies 2 in the second direction Y can be adjusted according to the size of the output pole connecting piece 102 to be fixed along the second direction Y. For example, when the size of the output pole connecting piece 102 to be fixed along the second direction Y is 10 mm, the spacing between the two limiting assemblies 2 along the second direction Y can be adjusted to 10.5 mm.

[0066] When adjusting the spacing between the two limit components 2 along the second direction Y, the first limit component 2 can be moved toward / away from the second limit component 2, the second limit component 2 can be moved toward / away from the first limit component 2, or the two limit components 2 can be moved toward / away from each other at the same time to reduce / increase the spacing between the two limit components 2. This embodiment of the present application does not limit this.

[0067] When the two limiting components 2 are fixed to the two ends of the base body 1 along the second direction Y, the position of the output pole connecting piece 102 can be limited in the second direction Y, which can reduce the possibility of the output pole connecting piece 102 shaking relative to the base body 1 and improve the safety of the battery 100.

[0068] In the embodiment of the present application, the two limiting assemblies 2 of the output pole base 103 are movably connected to the two ends of the base body 1 along the second direction Y. By moving the limiting assemblies 2, the spacing between the two limiting assemblies 2 along the second direction Y can be adjusted to accommodate output pole connecting pieces 102 of different specifications. Furthermore, when the limiting assemblies 2 are damaged, the limiting assemblies 2 can be easily removed from the base body 1 and replaced, without the need to remove the entire output pole base 103 from the end plate 101 and then replace it. Therefore, the output pole base 103 provided in the embodiment of the present application can be used to fix output pole connecting pieces 102 of different specifications, with high universality and high maintainability, and low maintenance workload and difficulty.

[0069] Figure 4 and Figure 5 The schematic diagram of the structure of the output pole base 103 provided in the embodiment of the present application fixing the output pole connecting pieces 102 of different specifications is shown. Figure 4 As shown, the distance between the two limiting components 2 in the output pole base 103 along the second direction Y is L1. Figure 5 As shown, the distance between the two limiting components 2 in the output pole base 103 along the second direction Y is L2. For example, L1 can be 22mm, L2 can be 28mm, L1<L2, Figure 4 The middle output pole base 103 can be used to fix the narrow output pole connecting piece 102. Figure 5 The middle output pole base 103 can be used to fix the wider output pole connecting piece 102 .

[0070] In some embodiments, as Figure 6 and Figure 7 As shown, the limiting assembly 2 may include a first connecting plate 21, a second connecting plate 22, and a limiting plate 23. The first connecting plate 21 and the second connecting plate 22 are spaced apart along the first direction X, and the limiting plate 23 is used to connect one end of the first connecting plate 21 and the second connecting plate 22. A receiving groove 24 is formed between the first connecting plate 21, the second connecting plate 22, and the limiting plate 23, and the end of the base body 1 along the second direction Y is mounted in the receiving groove 24.

[0071] The ends of the first and second connecting plates 21, 22 near the limiting plate 23 can be connected to the side of the limiting plate 23 facing the base body 1. The first and second connecting plates 21, 22 can be arranged in parallel, and the spacing between the first and second connecting plates 21, 22 along the first direction X can be set based on the thickness of the end of the base body 1 along the second direction Y. The thickness of the end of the base body 1 along the second direction Y is the dimension of the end of the base body 1 along the second direction Y in the first direction X.

[0072] The limiting plate 23 may protrude from the side of the base body 1 facing away from the end plate 101 along the first direction X. Thus, the two limiting plates 23 located at both ends of the base body 1 along the second direction Y may limit the position of the output pole connecting piece 102 in the second direction Y.

[0073] The receiving groove 24 formed between the first connecting plate 21, the second connecting plate 22 and the limiting plate 23 can be a U-shaped receiving groove 24. The end of the base body 1 along the second direction Y can be partially accommodated in the receiving groove 24, or can be fully accommodated in the receiving groove 24. This embodiment of the present application does not limit this. When the end of the base body 1 along the second direction Y is installed in the receiving groove 24, the surface of the first connecting plate 21 facing the second connecting plate 22 can be tightly attached to the surface of the base body 1 facing the first connecting plate 21, and the surface of the second connecting plate 22 facing the first connecting plate 21 can be tightly attached to the surface of the base body 1 facing the second connecting plate 22. In this way, the first connecting plate 21 and the second connecting plate 22 can clamp the end of the base body 1 along the second direction Y, thereby improving the fixing reliability of the limiting component 2 at the end of the base body 1 along the second direction Y.

[0074] An accommodating groove 24 is formed between the limiting plate 23 of the limiting assembly 2 and the two connecting plates. By installing the end of the base body 1 along the second direction Y in the accommodating groove 24, the connection of the limiting assembly 2 to the end of the base body 1 along the second direction Y can be achieved. The connection method is simple and easy, which improves the efficiency of connecting the limiting assembly 2 and the base body 1.

[0075] In some embodiments, as Figures 6 to 9 As shown, one end of the second connecting plate 22 can be rotatably connected to the limiting plate 23.

[0076] For example, the end portion of the second connecting plate 22 close to the limiting plate 23 can be rotatably connected to a side of the limiting plate 23 close to the base body 1 .

[0077] One end of the second connecting plate 22 is rotatably connected to the limiting plate 23, as shown in FIG. Figure 8 and Figure 9 As shown in FIG, when the second connecting plate 22 is rotated, the slot size of the receiving slot 24 can be changed. Figure 8 As shown, when the second connecting plate 22 is rotated in a direction away from the first connecting plate 21, the slot size of the accommodating slot 24 can be increased; Figure 9 As shown, when the second connecting plate 22 is rotated toward the first connecting plate 21, the size of the slot of the accommodating groove 24 can be reduced. The slot of the accommodating groove 24 is the opening formed between the end of the first connecting plate 21 not connected to the limiting plate 23 and the end of the second connecting plate 22 not connected to the limiting plate 23.

[0078] To install the stopper assembly 2 at both ends of the base body 1 along the second direction Y, the second connecting plate 22 can be first rotated away from the first connecting plate 21 to increase the size of the slot of the receiving groove 24. Then, the end of the base body 1 along the second direction Y is inserted into the installation slot. Finally, the second connecting plate 22 is rotated toward the first connecting plate 21 to decrease the size of the slot of the receiving groove 24, thereby clamping the end of the base body 1 along the second direction Y in the receiving groove 24.

[0079] By rotatably connecting one end of the second connecting plate 22 to the limiting plate 23, the size of the slot of the receiving groove 24 can be easily adjusted by rotating the second connecting plate 22, thereby facilitating the installation of both ends of the base body 1 along the second direction Y into the receiving groove 24, thereby achieving a movable connection between the base body 1 and the limiting assembly 2. Based on this, the end of the base body 1 along the second direction Y can be configured to cooperate with the receiving groove 24 in an interference fit, thereby improving the reliability of the connection between the base body 1 and the limiting assembly 2 without increasing the difficulty of installation.

[0080] In order to achieve the rotational connection between the second connecting plate 22 and the limiting plate 23, in some embodiments, a first hinge piece may be provided on the limiting plate 23, and a second hinge piece may be provided on the second connecting plate 22. The limiting plate 23 and the second connecting plate 22 can be rotationally connected by a hinge structure including the first hinge piece and the second hinge piece.

[0081] In other embodiments, the limiting plate 23 and the second connecting plate 22 can be rotatably connected through a shaft hole structure.

[0082] For example, Figure 10 As shown, the limiting plate 23 may be provided with a fixed shaft 231 , and one end of the second connecting plate 22 has a mounting hole 221 , and the fixed shaft 231 is inserted into the mounting hole 221 to rotatably connect the second connecting plate 22 to the limiting plate 23 .

[0083] The fixed shaft 231 can be an end portion of the limiting plate 23 near the second connecting plate 22, disposed along the second direction Y. The mounting hole 221 can be an end portion of the second connecting plate 22 near the limiting plate 23, disposed along the second direction Y. The cross-sectional shapes of the mounting hole 221 and the fixed shaft 231 can be circular, square, diamond, triangular, etc., as long as the mounting hole 221 matches the fixed shaft 231 and the fixed shaft 231 can be inserted into the mounting hole 221 without easily slipping out of the mounting hole 221. This is not a limitation in the present embodiment.

[0084] In this embodiment, by inserting the fixing shaft 231 into the mounting hole 221 , the second connecting plate 22 can be rotatably connected to the limiting plate 23 . The connection method is simple and highly operable.

[0085] In some embodiments, as Figure 2 As shown, at least one first limiting structure 11 is provided on the surface of the base body 1 at the end portion along the second direction Y facing the first connecting plate 21, and at least one second limiting structure 211 is provided on the surface of the first connecting plate 21 facing the base body 1. The first limiting structure 11 and the second limiting structure 211 cooperate with each other, and the base body 1 and the limiting assembly 2 are movably connected through the first limiting structure 11 and the second limiting structure 211.

[0086] like Figure 11 As shown, the base body 1 may include a first end 12, a second end 13 and a middle portion 14 along the second direction Y, wherein the first end 12 and the second end 13 are located on both sides of the middle portion 14. Both the first end 12 and the second end 13 may be provided with a first limiting structure 11.

[0087] Taking the first end portion 12 as an example, the number of the first limiting structures 11 provided on the first end portion 12 may be the same as the number of the second limiting structures 211 provided on the first connecting plate 21 , or may be different.

[0088] When the first end portion 12 is provided with one first limiting structure 11, the first limiting structure 11 can be provided at any position of the first end portion 12, for example, it can be provided at a position of the first end portion 12 close to the middle portion 14, or it can be provided at a position of the first end portion 12 away from the middle portion 14. When the first connecting plate 21 is provided with one second limiting structure 211, the second limiting structure 211 can be provided at any position of the first connecting plate 21, for example, it can be provided at a side of the first connecting plate 21 close to the middle portion 14 of the base body 1, or it can be provided at a side of the first connecting plate 21 away from the middle portion 14. As long as the first limiting structure 11 and the second limiting structure 211 cooperate with each other, the base body 1 and the limiting assembly 2 can be movably connected, and this embodiment of the present application does not limit this.

[0089] When there are multiple first limiting structures 11 and second limiting structures 211, the matching relationship between the multiple first limiting structures 11 and the multiple second limiting structures 211 is adjustable. For example, the first limiting structure 11 close to the outside can be matched with the second limiting structure 211 close to the inside, or the first limiting structure 11 close to the inside can be matched with the second limiting structure 211 close to the outside. When the first limiting structure 11 close to the outside is matched with the second limiting structure 211 close to the inside, the spacing between the two limiting components 2 along the second direction Y can be increased; when the first limiting structure 11 close to the inside is matched with the second limiting structure 211 close to the outside, the spacing between the two limiting components 2 along the second direction Y can be reduced. Among them, the outside refers to the side away from the middle part 14 of the base body 1, and the inside refers to the side close to the middle part 14 of the base body 1.

[0090] In this embodiment, the base body 1 and the limiting assembly 2 can be movably connected via the first limiting structure 11 and the second limiting structure 211. When there are multiple first limiting structures 11 and the second limiting structure 211, the spacing between the two limiting assemblies 2 along the second direction Y can be adjusted by adjusting the matching relationship between the multiple first limiting structures 11 and the multiple second limiting structures 211, which is conducive to expanding the applicable range of the output pole base 103.

[0091] It should be noted that, in order to achieve a movable connection between the base body 1 and the limiting assembly 2, in the embodiment of the present application, the first limiting structure 11 can also be arranged on the surface of the end of the base body 1 along the second direction Y facing the second connecting plate 22, and the second limiting structure 211 can be arranged on the surface of the second connecting plate 22 facing the base body 1. The embodiment of the present application does not limit the arrangement positions of the first limiting structure 11 and the second limiting structure 211.

[0092] In some embodiments, as Figure 2 、 Figure 6 、 Figure 7 、 Figure 11 As shown, one of the first limiting structure 11 and the second limiting structure 211 is a sliding groove, and the other is a sliding rail.

[0093] Taking the first end portion 12 of the base body 1 as an example, Figure 2 and Figure 11 As shown, the first limiting structure 11 can be a slide groove formed by the upper surface of the first end portion 12 being recessed toward the lower surface, and the second limiting structure 211 can be a slide rail formed by the lower surface of the first connecting plate 21 being protruded toward the second connecting plate 22. Alternatively, the first limiting structure 11 can be a slide rail formed by the upper surface of the first end portion 12 being protruded toward the first connecting plate 21, and the second limiting structure 211 can be a slide groove formed by the lower surface of the first connecting plate 21 being recessed toward the upper surface. Wherein, the upper surface of the first end portion 12 is the surface of the first end portion 12 facing the first connecting plate 21, and the lower surface of the first end portion 12 is the surface of the first end portion 12 facing the second connecting plate 22; the upper surface of the first connecting plate 21 is the surface of the first connecting plate 21 facing away from the second connecting plate 22, and the lower surface of the first connecting plate 21 is the surface of the first connecting plate 21 facing the second connecting plate 22.

[0094] One of the first limiting structure 11 and the second limiting structure 211 is set as a slide groove, and the other is set as a slide rail, so that one of the first limiting structure 11 and the second limiting structure 211 can slide along the other, so that the limiting component 2 can be movably connected or disassembled on the base body 1 by sliding. The disassembly and assembly method is simple and easy, which can improve the disassembly and assembly efficiency of the limiting component 2.

[0095] In some embodiments, as Figure 2 、 Figure 6 、 Figure 7 、 Figure 11 As shown, the first limiting structure 11 and the second limiting structure 211 are extended along the third direction Z; alternatively, the first limiting structure 11 and the second limiting structure 211 are extended along the second direction Y, which is not shown in the figure.

[0096] When the first limiting structure 11 and the second limiting structure 211 extend along the third direction Z, the limiting assembly 2 can be movably connected to the end of the base body 1 along the second direction Y along the third direction Z. When the first limiting structure 11 and the second limiting structure 211 extend along the second direction Y, the limiting assembly 2 can be movably connected to the end of the base body 1 along the second direction Y along the second direction Y. The embodiment of the present application does not limit the extension direction of the first limiting structure 11 and the second limiting structure 211.

[0097] Through the above scheme, the limit component 2 can be movably connected to the end of the base body 1 along the second direction Y along the second direction Y, and the limit component 2 can also be movably connected to the end of the base body 1 along the second direction Y along the third direction Z, so that the connection between the limit component 2 and the base body 1 is more flexible and diverse.

[0098] In some embodiments, as Figure 2 and Figure 3 As shown, the output pole base 103 may further include a clamping plate 3. The clamping plate 3 protrudes from the side of the base body 1 facing away from the end plate 101 along the first direction X. The clamping plate 3 is fixed to the end of the second connecting plate 22 away from the limiting plate 23 to limit the position of the output pole connecting piece 102.

[0099] The clamping plate 3 can be fixed to the end of the second connecting plate 22 away from the limiting plate 23 after being installed in the accommodating groove 24 at the end of the base body 1 along the second direction Y. Alternatively, the clamping plate 3 can be first fixed to the end of the second connecting plate 22 away from the limiting plate 23, and then the end of the base body 1 along the second direction Y can be installed in the accommodating groove 24. The embodiments of the present application do not limit this.

[0100] When the end portion of the base body 1 along the second direction Y is mounted in the receiving groove 24 , the clamping plate 3 may be parallel to the limiting plate 23 .

[0101] The clamping plate 3 protrudes from the side of the base body 1 facing away from the end plate 101 along the first direction X, so that the clamping plate 3 can cooperate with the limiting plate 23 to limit the position of the output pole connecting piece 102 along the third direction Z. When the base body 1 is provided with a clamping plate 3 at both ends along the second direction Y, and both clamping plates 3 protrude from the side of the base body 1 facing away from the end plate 101 along the first direction X, the two clamping plates 3 can limit the position of the output pole connecting piece 102 along the third direction Z.

[0102] In some embodiments, as Figure 6 and Figure 7 、 Figure 12 As shown, the end of the second connecting plate 22 away from the limiting plate 23 can be provided with an elastic portion 222, and the position of the clamping plate 3 opposite to the elastic portion 222 is provided with a clamping groove 31, and the elastic portion 222 and the clamping groove 31 cooperate with each other.

[0103] The elastic portion 222 can be a snap fastener that snaps into and engages with the slot 31. The elastic portion 222 can be made of a material with good wear resistance, such as metal. This can extend the service life of the elastic portion 222. The elastic portion 222 can also be made of the same material as the second connecting plate 22, such as plastic or rubber. This allows the elastic portion 222 to be integrally formed with the second connecting plate 22, reducing manufacturing costs.

[0104] like Figure 13 As shown, the elastic portion 222 may include a first elastic cantilever 222a and a second elastic cantilever 222b, each of which includes a fixed end and a free end. The fixed end of the first elastic cantilever 222a and the fixed end of the second elastic cantilever 222b are both fixedly connected to the end of the second connecting plate 22 away from the limiting plate 23, and the free ends of the first elastic cantilever 222a and the second elastic cantilever 222b extend toward the clamping plate 3.

[0105] When the free ends of the first elastic cantilever 222a and the second elastic cantilever 222b are applied with opposing forces, the free ends of the first elastic cantilever 222a and the second elastic cantilever 222b approach each other, and the elastic portion 222 is able to extend into the slot 31. The first elastic cantilever 222a and the second elastic cantilever 222b are elastic. Figure 14 and Figure 15 As shown, the free end of the first elastic cantilever 222 a and the free end of the second elastic cantilever 222 b can be engaged with the card slot 31 and maintain the engaged state, thereby achieving the connection between the card plate 3 and the second connecting plate 22 .

[0106] It should be noted that, in order to improve the connection strength between the clamping plate 3 and the second connecting plate 22, the number of elastic portions 222 can be multiple, and they can be spaced apart at the end of the second connecting plate 22 away from the limiting plate 23. Correspondingly, the number of the clamping slots 31 can also be multiple, and the multiple clamping slots 31 are aligned with the multiple elastic portions 222 one by one.

[0107] In this embodiment, the connection between the clamping plate 3 and the second connecting plate 22 can be achieved by snapping the elastic portion 222 into the slot 31 . This connection method is simple and reliable, and can improve the assembly efficiency of the output pole base 103 .

[0108] In some embodiments, as Figures 13 to 15 As shown, the end of the second connecting plate 22 away from the limiting plate 23 may be provided with a positioning column 223, as shown in FIG. Figure 12 As shown, a positioning hole 32 is provided at a portion of the clamping plate 3 opposite to the positioning post 223 , and the positioning post 223 and the positioning hole 32 cooperate with each other.

[0109] The positioning post 223 may be a hollow columnar structure or a solid columnar structure. The cross-sectional shape of the positioning post 223 may be circular, square, diamond, triangular, etc. The cross-sectional shape of the positioning post 223 is the cross-sectional shape of the positioning post 223 along the first direction X.

[0110] The dimension of the positioning column 223 along the third direction Z can be larger than the dimension of the elastic part 222 along the third direction Z. In this way, when the clamping plate 3 approaches the second connecting plate 22 to fix the clamping plate 3 at the end of the second connecting plate 22 away from the limit plate 23, the positioning column 223 can first enter the positioning hole 32, providing a position guide for the assembly of the clamping plate 3 and the second connecting plate 22, so as to facilitate the elastic part 222 to be quickly and accurately inserted into the slot 31.

[0111] The provision of the positioning posts 223 can provide positional guidance for the assembly of the snap-in plate 3 and the second connecting plate 22, facilitating the quick and accurate insertion of the elastic portion 222 into the snap-in slot 31. Furthermore, when the base body 1 has positioning posts 223 at both ends along the second direction Y, if the base body 1 shakes or rotates relative to the end plate 101, the positioning posts 223 can bear some of the force, effectively reducing the force acting on the elastic portion 222, thereby reducing damage to the elastic portion 222, a consumable component, and extending the service life of the output pole base 103.

[0112] In some embodiments, as Figure 12 As shown, a clamping portion 33 may be provided on a surface of the clamping plate 3 facing the base body 1 , and the clamping portion 33 is clamped on a surface of the first connecting plate 21 facing away from the base body 1 .

[0113] The clamping portion 33 may be a boss protruding from a side of the clamping plate 3 facing the base body 1 , and the boss may extend along the second direction Y. Along the second direction Y, the size of the boss may be smaller than or equal to the size of the clamping plate 3 .

[0114] The clamping portion 33 is clamped on the surface of the first connecting plate 21 facing away from the base body 1 to facilitate clamping the end of the base body 1 along the second direction Y in the receiving groove 24, thereby reducing the possibility of the limiting component 2 shaking relative to the base body 1.

[0115] Furthermore, in some embodiments, Figure 6 and Figure 7 As shown, the surface of the first connecting plate 21 facing away from the base body 1 can be provided with a snap-in groove 212 recessed toward the second connecting plate 22 on the side near the snap-in plate 3. The snap-in portion 33 can be snapped into the snap-in groove 212 to lock the limit assembly 2 and the base body 1. In this case, the side of the snap-in portion 33 facing away from the second connecting plate 22 can be flush with the surface of the first connecting plate 21 facing away from the second connecting plate 22 in the first direction X, thereby providing more space for the output pole connecting piece 102 in the third direction Z, reducing the possibility of interference with the output pole connecting piece 102 due to the snap-in portion 33 protruding from the surface of the first connecting plate 21 facing away from the second connecting plate 22.

[0116] According to some embodiments of the present application, Figure 1 、 Figure 4 and Figure 5 As shown, the present embodiment further provides a battery 100, comprising a plurality of battery cells 104, an end plate 101, an output electrode connecting piece 102, and the output electrode base 103 of the previous embodiment.

[0120] According to some embodiments of the present application, see Figures 1 to 9 The present application provides an output pole base 103, comprising a base body 1, two limiting assemblies 2 and two clip-on plates 3. The base body 1 is used to fix the output pole connecting piece 102 and is fixed to the end plate 101 along the first direction X.
