Wherein permanently attached means that the attached parts are not separated, for example, the fasteners may include rivets or the like; semi-permanent connection means that the connected parts, although they can be disassembled, often cause damage to the fasteners used, e.g., the fasteners may include cotter pins or the like; removable connection means that the connected parts are easily removed, for example, the fasteners may be screws, or bolts, or threaded bolts and nuts, etc.

For example, the second fastener 7 can detachably connect the mounting piece 5 with the bearing piece 1, so that the battery unit 2 can be replaced and overhauled conveniently; it will be appreciated that if the battery unit 2 is located closer to the opening, it is possible to choose whether the mounting member 5 is required to be detached from the carrier member 1 according to the actual operating requirements. For example, the first fastener 6 detachably connects the mount 5 with the battery cell 21; of course, the mounting 5 and the battery cell 21 may also be permanently or semi-permanently connected by the first fastener 6.

In some embodiments, as shown in fig. 3, the axial direction of the second fastener 7 is perpendicular to the axial direction of the first fastener 6, so as to allow the first fastener 6 and the second fastener 7 to better adapt to the relative positions of the battery cell 21, the mounting member 5, and the carrier member 1, facilitating the placement of the first fastener 6 and the second fastener 7.

In some embodiments, as shown in fig. 3, the first fastener 6 is penetrating through the mounting piece 5 and the battery cell 21 along the length direction of the carrier 1, so that the axial direction of the first fastener 6 can be parallel to the length direction of the carrier 1, so that the first fastener 6 is better adapted to the arrangement of the mounting piece 5 and the battery cell 21 sequentially arranged along the length direction of the carrier 1, and the first fastener 6 is ensured to reliably fix the mounting piece 5 and the battery cell 21; the second fastening piece 7 penetrates through the mounting piece 5 and the bearing piece 1 along the width direction of the bearing piece 1, so that the axial direction of the second fastening piece 7 can be parallel to the width direction of the bearing piece 1, the second fastening piece 7 can be well adapted to the relative arrangement of the mounting piece 5 and the cavity wall of the mounting cavity 1a, and the second fastening piece 7 is ensured to reliably fix the mounting piece 5 and the bearing piece 1.

Of course, the second fastening member 7 may also penetrate through the mounting member 5 and the carrier 1 along the height direction of the carrier 1, so that the axial direction of the second fastening member 7 is parallel to the height direction of the carrier 1, which is also convenient for the second fastening member 7 to better adapt to the relative arrangement of the mounting member 5 and the cavity wall of the mounting cavity 1a, and ensures that the second fastening member 7 reliably fixes the mounting member 5 and the carrier 1. The length direction of the carrier 1, the width direction of the carrier 1 and the height direction of the carrier 1 are perpendicular to each other.

In some embodiments, as shown in fig. 1-4, the number of connecting elbows 4 is multiple, and in the length direction of the carrier 1, the plurality of connecting elbows 4 are located on the same side of the plurality of battery units 2, so when the battery assembly 100 is assembled, the plurality of connecting elbows 4 can be arranged on the same side of the plurality of battery units 2 in the length direction of the carrier 1, so as to simplify the assembly procedure of the plurality of connecting elbows 4, facilitate the arrangement and assembly of the plurality of connecting elbows 4, and meanwhile, the plurality of connecting elbows 4 only need to occupy the space of one side of the battery unit 2 in the length direction of the carrier 1, so as to facilitate the improvement of the space utilization rate of the battery assembly 100.

It can be seen that when the plurality of connecting elbows 4 are located on the same side of the plurality of battery cells 2 in the length direction of the carrier 1, the inlet 3a and the outlet 3b of the flow channel of the heat exchange member 3 can be located at the same end of the heat exchange member 3 in the length direction of the carrier 1, thereby facilitating the assembly of the plurality of heat exchange members 3 and the plurality of connecting elbows 4.

In some embodiments, as shown in fig. 1, the carrier 1 is a profile, so as to ensure the bearing capacity of the carrier 1, and the reliability of the battery assembly 100, so that the carrier 1 ensures the normal operation of the battery unit 2 and the heat exchange member 3, and meanwhile, the carrier 1 has various cross-sectional forms, which is beneficial to ensure that the carrier 1 defines a mounting cavity 1a matched with the battery unit 2 and the heat exchange member 3, thereby facilitating the provision of a proper mounting space for the arrangement of the battery unit 21 and the heat exchange member 3.

In some embodiments, as shown in fig. 5 and 7, the battery unit 2 includes a plurality of battery cells 21, and the plurality of battery cells 21 may be sequentially disposed along the width direction of the carrier 1; the heat exchange piece 3 includes a plurality of first heat exchange pieces 31, a plurality of first heat exchange pieces 31 and a plurality of battery monomer 21 set gradually alternately along the width direction of carrier 1 for be equipped with a battery monomer 21 between two adjacent first heat exchange pieces 31, and be equipped with a first heat exchange piece 31 between two adjacent battery monomer 21 that belong to same battery unit 2, thereby every battery monomer 21 can carry out the heat exchange with one or two first heat exchange pieces 31, with the cooling efficiency or the intensification efficiency of guaranteeing heat exchange piece 3 to a plurality of battery monomer 21, make battery monomer 21 and first heat exchange piece 31 arrange more nimble simultaneously, be convenient for realize battery unit 21, first heat exchange piece 31 and carrier 1's integrated design, with the design of simplifying the arrangement of first heat exchange piece 31 in installation cavity 1a, make full use of the inner space of installation cavity 1a is in order to satisfy battery unit 2's heat transfer demand, guarantee battery unit 2's normal work.

It can be seen that the above arrangement of the first heat exchange member 31 is convenient for fully utilizing the space-limited installation cavity 1a, so that at least one first heat exchange member 31 is arranged in the interval between two adjacent battery cells 21 to separate the two adjacent battery cells 21, thereby being beneficial to rapid cooling and rapid heating of the battery cells 21 and improving the temperature control efficiency of the battery cells 2.

It is understood that the number of the first heat exchanging members 31 in the heat exchanging member 3 may be equal to or different from the number of the battery cells 21 in the battery unit 2, for example, the battery unit 2 includes n battery cells 21, and the number of the first heat exchanging members 31 of the heat exchanging member 3 is n, or (n-1), or (n+1); therefore, the arrangement of the first heat exchange member 31 is convenient for reasonably increasing or reducing the number of the first heat exchange members 31 according to the number of the battery cells 21, so that the number of the first heat exchange members 31 is matched with the number of the battery cells 21, and the temperature control efficiency of the battery cells 2 is effectively ensured.

As shown in fig. 5 and 7, the heat exchange member 3 further includes at least one second heat exchange member 32, the second heat exchange member 32 connects adjacent two first heat exchange members 31 such that the channels of the plurality of first heat exchange members 31 are arranged in series, and then the outlets of the channels of the adjacent two first heat exchange members 31 are communicated to the inlets of the channels of the other first heat exchange member 31 through the second heat exchange member 32, so that the heat exchange medium can flow into the heat exchange member 3 through the inlet of the channel of one of the plurality of first heat exchange members 31 and sequentially flow through the channels of the plurality of first heat exchange members 31.

The second heat exchange member 32 is wound around one end of the battery monomer 21 between two adjacent first heat exchange members 31 in the height direction of the bearing member 1, so that one end of the corresponding battery monomer 21 in the height direction of the bearing member 1 can have a certain supporting effect on the second heat exchange member 32, so that the limit of the second heat exchange member 32 is conveniently realized, the arrangement of the second heat exchange member 32 is convenient, the flow channels of the plurality of heat exchange members 3 can be formed into an integral flow path, and the circulating flow of the heat exchange medium in the flow channels of the plurality of heat exchange members 3 is conveniently realized, so that the heat exchange efficiency of the heat exchange members 3 and the battery monomer 21 is further improved.

In addition, the second heat exchange pieces 32 are connected with two adjacent first heat exchange pieces 31 to realize the serial arrangement of the runners of a plurality of first heat exchange pieces 31, so that the number of the second heat exchange pieces 32 can be 1 less than that of the first heat exchange pieces 31, and the number of the second heat exchange pieces 32 can be appropriately increased or reduced according to the number of the first heat exchange pieces 31, so that the number of the second heat exchange pieces 32 is matched with that of the first heat exchange pieces 31, and meanwhile, the connection among the plurality of first heat exchange pieces 31 is facilitated to be simplified, the heat exchange pieces 3 can adapt to different numbers of battery cells 21, the mounting cavities 1a with different space sizes are further defined by the bearing pieces 1, and the universality of the battery assembly 100 is improved.

It is understood that the first heat exchanging member 31 is in heat conducting engagement with the battery cell 21, and the second heat exchanging member 31 is also in heat conducting engagement with the battery cell 21; for example, the first heat exchanging member 31 and the second heat exchanging member 32 are each formed as a flat plate. When the number of the first heat exchanging members 31 is two, the number of the second heat exchanging members 32 may be one, and at this time, the second heat exchanging members 32 may be wound around any one end of the battery cell 21 located between the two first heat exchanging members 31 in the height direction of the carrier 1; when the first heat exchange members 31 are three or more, the second heat exchange members 32 are plural, and since the flow channels of the plural first heat exchange members 31 are arranged in series through the second heat exchange members 32, the heat exchange members 3 can extend in S shape through the interval between the adjacent two battery cells 21, and the heat exchange members 3 can be wound along the height direction of the bearing member 1, so that the arrangement of the heat exchange members 3 is simplified, and at this time, the adjacent two second heat exchange members 32, namely, the second heat exchange member 32 at the inlet and the second heat exchange member 32 at the outlet of the channel of the same first heat exchange member 31, are respectively arranged at two sides of the battery cell 2 in the height direction of the bearing member 1.

Illustratively, in the examples of fig. 5 and 7, the heat exchange member 3 includes 4 first heat exchange members 31 and 3 second heat exchange members 32.

Optionally, in the examples of fig. 3 to 5, the positive electrode post 211 and the negative electrode post 212 of the battery cell 21 are disposed at corresponding ends of the battery cell 21 in the length direction of the carrier 1, and the positive electrode post 211 and the negative electrode post 212 may be located at the same end or different ends of the battery cell 21, where the ends of the battery cell 21 in the height direction of the carrier 1 are not provided with posts, which further facilitates the arrangement of the second heat exchange member 32, i.e. the posts of the battery cell 21 do not need to make room for the second heat exchange member 32.

In some embodiments, as shown in fig. 1-5, the battery unit 2 includes a plurality of battery cells 21 that are disposed at intervals along the width direction of the carrier 1, where the positive electrode post 211 and the negative electrode post 212 of the battery cell 21 are respectively located at two ends of the battery cell 21 in the length direction of the carrier 1, and the posts at the same end of the adjacent two battery cells 21 are disposed at intervals along the height direction of the carrier 1, so that the posts at the same end of the adjacent two battery cells 21 are located at different positions in the height direction of the carrier 1, so as to increase the air gap between the two posts electrically connected by the connecting piece 22, so that the creepage distance between the two posts electrically connected by the connecting piece 22 (creepage distance refers to the creepage distance between two conductive parts measured along the insulating surface) between the adjacent battery cells, and under different use conditions, since the insulating material around the conductors is polarized, the insulating material presents a charged region of a charged phenomenon) can meet design requirements such as national standard requirements, and at the same time, the creepage distance between the battery cells can be effectively increased in a safe manner even if the overall dimension of the battery cell is smaller; meanwhile, on the premise that the two adjacent battery monomers 21 can be reliably and electrically connected, the pole posts of the two adjacent battery monomers 21 can provide avoidance space for the arrangement of the corresponding connecting bent pipe 4, so that the arrangement of the connecting bent pipe 4 is facilitated.

Moreover, the positive electrode post 211 and the negative electrode post 212 of the same battery cell 21 are arranged at intervals along the height direction of the bearing piece 1, so that when the connecting bent pipes 4 are multiple, two adjacent connecting bent pipes 4 are positioned at the same height position in the height direction of the battery cell 21, the situation that the heat exchange piece 3 has a torsion trend when wound is avoided, and the stress of the heat exchange piece 3 is improved.

In the battery unit 2, the plurality of battery cells 21 may be connected in series or parallel or a series-parallel connection, and a series-parallel connection means that the plurality of battery cells 21 are connected in series or parallel. It can be seen that when the number of battery cells 21 is plural, for a single battery cell 21, the single battery cell 21 may directly supply power to the electric device of the vehicle 200, or at least one of the single battery cell 21 and the adjacent other battery cells 21 may be connected in series to supply power to the electric device. In the description of the present application, the meaning of "plurality" is two or more.

For example, in the examples of fig. 1, 2, 10 and 11, the plurality of battery cells 21 of the battery unit 2 are sequentially arranged along the width direction of the carrier 1, the battery cells 21 are in a cuboid structure, the two ends of the length of each battery cell 21 are respectively provided with a positive electrode post 211 and a negative electrode post 212, in the height direction of the carrier 1, the positive electrode posts 211 and the negative electrode posts 212 are arranged at intervals, the polarities of the posts at the same end of two adjacent battery cells 21 are opposite, and then all the positive electrode posts 211 at the same end of the plurality of battery cells 21 of the battery unit 2 are positioned at the first height position and all the negative electrode posts 212 are positioned at the second height position. In the height direction of the battery cells 21, the connecting bend 4 can be located at a third height position, i.e. the connecting bend 4 and the positive and negative electrode columns 211, 212 on the same side can be arranged offset in the height direction of the carrier 1.

As shown in fig. 2, one end of the battery cell 21 corresponding to the connecting bent tube 4 in the length direction of the carrier 1 is provided with the connecting bent tube 4 and the negative electrode post 212, and in the height direction of the carrier 1, the second height position is located between the third height position and the first height position, and in the height direction of the carrier 1, the connecting bent tube 4 is located at one side of the negative electrode post 212 away from the positive electrode post 211; of course, the end of the battery cell 21 corresponding to the connecting bent tube 4 in the length direction of the carrier 1 may also be provided with the connecting bent tube 4 and the positive electrode post 211, and in the height direction of the carrier 1, the first height position is located between the third height position and the second height position, and then in the height direction of the carrier 1, the connecting bent tube 4 is located at one side of the positive electrode post 211 away from the negative electrode post 212.

As shown in fig. 11, the connection bent pipe 4 and the positive electrode post 211 are disposed at one end of the connection bent pipe 4 in the length direction of the carrier 1, and in the height direction of the carrier 1, the second height position is located between the third height position and the first height position, or the second height position is flush with the third height position, so that in the height direction of the carrier 1, the positive electrode post 211 can provide a larger arrangement space for the connection bent pipe 4; of course, the end of the battery unit 21 corresponding to the connecting bent pipe 4 in the length direction of the carrier 1 may further be provided with the connecting bent pipe 4 and the negative electrode post 212, and in the height direction of the carrier 1, the first height position is located between the third height position and the second height position, or the first height position is flush with the third height position, so that in the height direction of the carrier 1, the negative electrode post 212 may provide a larger arrangement space for the connecting bent pipe 4.

In some embodiments, as shown in fig. 1, the battery cell 21 has two heat exchange sidewalls disposed opposite to each other along the width direction of the carrier 1, where the heat exchange sidewalls are sidewalls with the largest surface area among the sidewalls of the battery cell 21, that is, the heat exchange sidewalls can be understood as "large sides" of the battery cell 21; the first heat exchange member 31 is in heat conduction fit with the heat exchange side wall, so that a larger heat exchange area is formed between the first heat exchange member 31 and the adjacent battery cell 21, and a larger heat exchange efficiency is ensured between the first heat exchange member 31 and the adjacent battery cell 21, so that the temperature control efficiency of the heat exchange member 3 to the battery cell 21 is further improved.

For example, in the examples of fig. 1 and 2, the area of the heat exchange sidewall of the battery cell 21 is larger than the area of the rest of the sidewalls of the battery cell 21, and the first heat exchange member 31 is in surface contact with the heat exchange sidewall of the adjacent battery cell 21, so that the contact area between the battery cell 21 and the first heat exchange member 31 is increased, and the heat exchange efficiency between the heat exchange member 3 and the battery cell 21 is improved, so that the rapid cooling and the rapid heating of the battery cell 21 by the heat exchange member 3 are realized.

Alternatively, in the examples of fig. 1 to 4, the battery cell 21 has a rectangular parallelepiped structure, the length direction of the battery cell 21 is the same as the length direction of the carrier 1, the thickness direction of the battery cell 21 is the same as the width direction of the carrier 1, the height direction of the battery cell 21 is the same as the height direction of the carrier 1, and the length of the battery cell 21 > the height of the battery cell 21 > the thickness of the battery cell 21, for example, the battery cell 21 is a blade battery, so that a suitable number of battery cells 21 can be mounted in one mounting cavity 1 a.

Of course, the manner of placement of the battery cells 21 relative to the carrier 1 is not limited thereto; in other embodiments, the battery cell 21 has a rectangular parallelepiped structure, the length of the battery cell 21 > the height of the battery cell 21 > the thickness of the battery cell 21, the length direction of the battery cell 21 is the same as the length direction of the carrier 1, the height direction of the battery cell 21 may also be the same as the width direction of the carrier 1, and the thickness direction of the battery cell 21 is the same as the height direction of the carrier 1.

In the example of fig. 1 to 5, the plurality of battery cells 21 include first battery cells and second battery cells alternately arranged in sequence along the width direction of the carrier 1, and one second battery cell is disposed between two adjacent first battery cells, and one first battery cell is disposed between two adjacent second battery cells; the second heat exchange pieces 32 are multiple, the multiple second heat exchange pieces 32 are sequentially arranged along the width direction of the bearing piece 1, and the multiple second heat exchange pieces 32 comprise first plates and second plates which are sequentially and alternately arranged along the width direction of the bearing piece 1, one second plate is arranged between every two adjacent first plates, and one first plate is arranged between every two adjacent second plates.

The first plate is wound around one end of the corresponding first battery cell in the height direction of the bearing member 1 so as to connect the two first heat exchange members 31 on two sides of the first battery cell, and the second plate is wound around one end of the corresponding second battery cell far away from the first plate in the height direction of the bearing member 1 so as to connect the two first heat exchange members 31 on two sides of the second battery cell.

It can be seen that all the first plates of the heat exchange member 3 are located at one end of the battery unit 2 in the height direction of the carrier 1, and all the second plates of the heat exchange member 3 are located at the other end of the battery unit 2 in the height direction of the carrier 1, so that the heat exchange member 3 extends in an S shape through the interval between two adjacent battery cells 21, thereby realizing the serial arrangement of the channels of the plurality of first heat exchange members 31, facilitating the simplification of the arrangement of the heat exchange member 3 and the assembly of the battery assembly 100.

In some embodiments, as shown in fig. 3, fig. 4 and fig. 6, in the length direction of the carrier 1, the length of the second heat exchange member 32 is equal to that of the first heat exchange member 31, so as to ensure the heat exchange area of the second heat exchange member 32 and the battery unit 21, and meanwhile, the heat exchange medium flows between the first heat exchange member 31 and the second heat exchange member 31 relatively stably, so that the balance of the overall temperature control effect of the heat exchange member 3 is further ensured, and the influence on the overall performance of the battery unit 2 due to the excessively high and excessively low local temperature of the battery unit 21 is avoided.

For example, in the examples of fig. 3 to 5 and 7, the battery cell 21 is in a cuboid structure, the length of the battery cell 21 > the height of the battery cell 21 > the thickness of the battery cell 21, and then the two heat exchange side walls of the battery cell 21 are oppositely arranged along the thickness direction of the battery cell 21, the first heat exchange member 31 is arranged on one side of the adjacent battery cell 21 in the thickness direction of the battery cell 21, so that the first heat exchange member 31 is in heat conduction fit with the heat exchange side wall of the battery cell 21, and the second heat exchange member 32 is arranged on one side of the corresponding battery cell 21 in the height direction of the battery cell 21, so that a larger heat exchange area is also provided between the second heat exchange member 32 and the battery cell 21.

Optionally, in the examples of fig. 5 and 7, the number of the first heat exchanging members 31 of the heat exchanging member 3 is an even number, and the connecting bent pipes 4 are connected to the ends, far away from the second heat exchanging members 32, of the corresponding first heat exchanging members 31, so that when the connecting bent pipes 4 are a plurality of, the plurality of connecting bent pipes 4 are located on the same side of the battery unit 2 in the height direction of the carrier 1, so that the plurality of battery units 2 provide avoidance spaces for the plurality of connecting bent pipes 4, and meanwhile, the heat exchanging medium is convenient to fully fill the flow channels in the heat exchanging member 3, so as to further ensure the heat exchanging efficiency of the heat exchanging member 3 to the battery units 2.

Of course, in other embodiments of the present application, the number of the first heat exchanging members 31 of the heat exchanging members 3 may be an odd number; the relative arrangement of the connecting bend 4 and the first heat exchange member 31 is also not limited to the end of the connecting bend 4 that connects the first heat exchange member 31 away from the second heat exchange member 32.

In some embodiments, as shown in fig. 3, the battery assembly 100 further includes a mounting member 5, where the mounting member 5 is fixedly connected with the battery unit 2 and the carrier 1 respectively, so as to ensure that the battery unit 2 is stably mounted in the mounting cavity 1a, the battery unit 2 includes a plurality of battery units 21, and two adjacent battery units 21 are electrically connected through a connecting piece 22, for example, the connecting piece 22 connects the positive electrode post 211 of one of the two adjacent battery units 21 and the negative electrode post 212 of the other battery unit 21, so as to realize the serial connection of the two adjacent battery units 21.

The connecting piece 22 is clamped to the mounting piece 5 to limit the connecting piece 22 to move relative to the mounting piece 5 in the length direction of the bearing piece 1, so that stable matching of the connecting piece 22 and the pole of the battery cell 21 is ensured, and reliable electrical connection between the connecting piece 22 and the battery cell 21 is ensured.

It will be appreciated that the connecting piece 22 electrically connects the poles of the adjacent two cells 21, and that the connecting piece 22 cooperates with the corresponding poles of the adjacent two cells 21 such that the adjacent two cells 21 can restrict movement of the connecting piece 22 in the width direction of the carrier 1.

In some embodiments, as shown in fig. 3, the mounting member 5 is formed with a first slot 5b and a second slot 5c spaced along the height direction of the carrier member 1, the connecting piece 22 is respectively clamped with the first slot 5b and the second slot 5c, and the first slot 5b and the second slot 5c cooperate to limit the movement of the connecting piece 22 in the height direction of the carrier member 1, so that the connecting piece 22 is stably electrically connected with the adjacent battery cells 21, so as to ensure the reliability of the electrical connection, and facilitate the assembly of the connecting piece 22 and the mounting member 5.

Meanwhile, the connecting piece 22 is simply assembled with the bearing piece 1, and the connecting piece 22 is simply assembled with the pole, so that the connecting piece 22 is convenient to install.

In some embodiments, as shown in fig. 3 and 12, the mounting member 5 is provided with a mounting through hole 5a, and the post of the battery cell 21 is inserted through the mounting through hole 5a and is matched with the connecting piece 22, so that the assembly of the battery cell 21 and the carrier member 1 is simple, and the assembly of the connecting piece 22 and the post is simple, thereby facilitating the installation of the connecting piece 22. As shown in fig. 3, the first and second card grooves 5b and 5c are located at the side of the mounting through-hole 5a remote from the battery cell 21; alternatively, as shown in fig. 12, the first and second clamping grooves 5b and 5c are located on the peripheral wall of the mounting through hole 5a to ensure that the first and second clamping grooves 5b and 5c clamp the connection piece 22 in the height direction of the carrier 1, and to ensure the stability of the electrical connection of the connection piece 22 and the posts of the adjacent two battery cells 21.

For example, in the example of fig. 3, the mounting member 5 has a plurality of first clamping grooves 5b sequentially arranged along the width direction of the carrier 1, and the mounting member 5 has a plurality of second clamping grooves 5c sequentially arranged along the width direction of the carrier 1, the first clamping grooves 5b and the second clamping grooves 5c are located at one side of the mounting through holes 5a away from the battery cells 21, then the first clamping grooves 5b and the second clamping grooves 5c are located at both sides of the mounting member 5 in the height direction of the carrier 1, and the adjacent first clamping grooves 5b and second clamping grooves 5c are jointly clamped at both ends of the same connecting piece 22 to achieve the fixation of the connecting piece 22.

For example, in the example of fig. 12, the mounting member 5 has a plurality of first clamping grooves 5b sequentially arranged along the width direction of the carrier 1, and the mounting member 5 has a plurality of second clamping grooves 5c sequentially arranged along the width direction of the carrier 1, so that the first clamping grooves 5b and the second clamping grooves 5c are located at both sides of the mounting member 5 in the height direction of the carrier 1, and adjacent first clamping grooves 5b and second clamping grooves 5c are jointly clamped at both ends of the same connecting piece 22 to realize fixation of the connecting piece 22; wherein, the first clamping groove 5b and the second clamping groove 5c are both positioned on the peripheral wall of the mounting through hole 5a, and the mounting through hole 5a corresponds to a plurality of poles at this time, so as to provide a certain arrangement space for the first clamping groove 5a and the second clamping groove 5 c.

Alternatively, the structure of the mounting members 5 at both ends of the length of the battery cell 21 may be the same or different, improving the applicability of the mounting members 5.

Alternatively, in the example of fig. 3, there are a plurality of mounting through holes 5a, and each mounting through hole 5a is provided corresponding to one pole. Of course, one mounting through hole 5a may also correspond to a plurality of poles, so that a plurality of poles penetrate through the same mounting through hole 5a; for example, in the example of fig. 12, the mount 5 is formed with one mounting through hole 5a, and the mounting through hole 5a corresponds to all the poles located at one end of the length of the carrier 1.

Of course, the mounting member 5 may be further formed with a plurality of mounting through holes 5a, and the plurality of mounting through holes 5a may include a first mounting through hole corresponding to one of the poles and a second mounting through hole corresponding to a plurality of the poles.
