[0003] As the demand for clean energy increases, battery devices have been widely developed. Battery devices can store electrical energy and can be widely used in electronic devices such as mobile phones, laptop computers, battery cars, electric cars, electric airplanes, electric ships, electric toy cars, electric toy ships, electric toy airplanes, and electric tools.

[0004] How to improve the reliability of battery devices has always been the focus of attention during the research and development of battery devices. Summary of the invention

[0005] In view of the above problems, the present application provides a battery device, an output pole mounting seat and an electrical device to at least improve the reliability of the battery device.

[0006] The first aspect of the present application proposes a battery device, an output pole mounting seat and an electrical equipment, the battery device includes a box body, a battery cell, an output pole mounting seat and an output pole, the battery cell is arranged in the box body; the output pole mounting seat includes a seat body and an enclosure portion, the enclosure portion is connected to the seat body, and is surrounded by the seat body to form a accommodating space, at least one preset line passing area is arranged on the enclosure portion, and a shielding member is arranged in each preset line passing area, the shielding member is connected to the enclosure portion and / or the seat body as a whole through a weak structure, and the weak structure is arranged to be able to be destroyed so that the shielding member is separated from the preset line passing area to form a line passing hole in the preset line passing area; the output pole is conductively connected to the battery cell, and part of the output pole is located in the accommodating space and connected to the seat body.

[0007] In the technical solution of the embodiment of the present application, a shielding member is provided in the preset wire-passing area of ​​the output pole mounting seat, and the shielding member is connected to the seat body and / or the enclosure as a whole through a weak structure. The preset wire-passing area where wires need to be passed can be separated from the preset wire-passing area by destroying the weak structure to form a wire-passing hole, thereby meeting the wire-passing requirements of the output pole mounting seat. The output pole mounting seat has a simple structure and is easy to assemble. For the preset wire-passing area where wires do not need to be passed, the shielding member can be connected to the seat body more stably to shield the preset wire-passing area at the corresponding position, thereby reducing the possibility of the shielding member falling off, improving the protective effect of the output pole mounting seat, reducing the risk of electric shock for personnel during assembly, disassembly or after-sales maintenance of the battery device, and improving the reliability of the battery device.

[0008] In some embodiments of the present application, the enclosure is provided with at least two preset wire passing areas facing different directions. By providing preset wire passing areas facing different directions, the output pole mounting seat can be destroyed by the weak structure to form different wire outlet directions. In this way, a suitable preset wire passing area can be selected as needed to form a wire passing hole, thereby improving the convenience of arranging the conductive connector and simplifying the wiring space.

[0009] In some embodiments of the present application, the enclosure includes a first sub-enclosure and two second sub-enclosures, the two second sub-enclosures are arranged opposite to each other, the first sub-enclosure is connected between the two second sub-enclosures, and at least two of the first sub-enclosure and the two second sub-enclosures are provided with the preset wire passing area. The first sub-enclosure and the two second sub-enclosures face different directions respectively, and at least two of the first sub-enclosure and the two second sub-enclosures are provided with preset wire passing areas, so that the output pole mounting seat can be destroyed by the weak structure to form different wire output directions. In this way, a suitable preset wire passing area can be selected as needed to form a wire passing hole, which improves the convenience of arranging the conductive connector and helps to simplify the wiring space.

[0010] In some embodiments of the present application, the enclosure portion is provided with a notch, and the output pole is passed through the notch. The notch facilitates the output pole to enter the accommodating space, thereby improving the convenience of assembling the output pole and the output pole mounting seat.

[0011] In some embodiments of the present application, there is a spacing gap between some of the shielding members and the enclosure portion and / or the seat body surrounding the preset wire-passing area, and the weak structure and the spacing gap are arranged along the circumference of the preset wire-passing area. By providing the spacing gap, the convenience of the weak structure being destroyed by external force can be improved. When the weak structure is destroyed, the shielding member can be easily separated from the preset wire-passing area to form a wire-passing hole, which is convenient for operation.

[0012] In some embodiments of the present application, the spacing gaps include at least two, and the spacing gaps and the weak structures are arranged alternately along the circumference of the preset wire passing area. By arranging the spacing gaps and the weak structures alternately, the convenience of the weak structure being destroyed by external force can be improved. When the weak structure is destroyed, the shielding member can be easily separated from the preset wire passing area to form a wire passing hole, which is convenient for operation.

[0013] In some embodiments of the present application, along the circumference of the preset wire-passing area, the size of the weak structure is smaller than the size of the spacing gap. By making the size of the weak structure smaller than the size of the spacing gap, the convenience of the weak structure being destroyed by external force can be improved. When the weak structure is destroyed, the shielding member can be easily separated from the preset wire-passing area to form a wire-passing hole, which is convenient for operation.

[0014] In some embodiments of the present application, the shielding member includes a first side, a second side, a third side and a fourth side connected in sequence end to end, and at least one of the first side, the second side, the third side and the fourth side is connected to the weak structure.

[0015] In some embodiments of the present application, at least one of the first side, the second side, the third side and the fourth side is provided with the weakening structure in the middle of its extension direction. The weakening structure is connected to the middle of the side, thereby improving the stability of the shielding member fixed by the weakening structure.

[0016] In some embodiments of the present application, along the arrangement direction of the seat body and the enclosure, the preset line-passing area passes through one end of the enclosure toward the seat body; the second side and the fourth side are arranged opposite to each other and extend respectively along the arrangement direction of the seat body and the enclosure; the third side is located at one end of the shielding member toward the seat body; the second side and the fourth side are respectively provided with the weak structure between the enclosure, and the third side is provided with the seat body. By providing the weak structure in the middle of the three sides of the shielding member, the stability of the shielding member fixed by the weak structure is improved.

[0017] In some embodiments of the present application, the weak structure includes a first weak structure, the first weak structure is arranged at one end of the shielding member facing the seat body, and along the arrangement direction from the shielding member to the seat body, the destruction position of the first weak structure is closer to the seat body than the output pole located in the accommodating space, or the destruction position of the first weak structure is arranged flush with the output pole located in the accommodating space. The conductive connector connected to the output pole is not easy to interfere with the residual structure of the first weak structure, which reduces the possibility of the conductive connector being lifted up and causing improper assembly, thereby causing abnormal temperature rise and causing damage, and improves the reliability of the battery device.

[0018] In some embodiments of the present application, the surface of the seat body facing the accommodating space is a first end surface, a fixing portion is arranged on the first end surface, the fixing portion has a supporting surface, and the output pole is fixed to the supporting surface; the damage position of the first weak structure is arranged closer to the seat body than the supporting surface, or the damage position of the first weak structure is arranged flush with the supporting surface. After the first weak structure is damaged, its residual structure is lower than the supporting surface or flush with the supporting surface, and the output pole is not easy to interfere with the residual structure, which reduces the possibility of the output pole being tilted by the residual structure, improves the fixing stability and connection reliability between the output pole and the seat body, reduces the risk of poor contact or ablation caused by the output pole, and improves the reliability of the battery device. In some embodiments of the present application, along the arrangement direction of the seat body and the enclosure, the preset wire-passing area passes through one end of the enclosure toward the seat body, the first weak structure is connected to the first end face, and the support surface is protruded relative to the first end face toward the accommodating space. The first weak structure extends from the first end face toward the enclosure, so that the first weak structure forms an easily-destructible damage position at the connection with the first end face. Since the support surface protrudes relative to the first end face, the easily-destructible damage position is lower than the support surface. In this way, when the first weak structure is destroyed, it is easier to achieve that the residual structure does not exceed the height of the support surface, thereby improving the convenience of the first weak structure being destroyed to form a wire-passing hole. In some embodiments of the present application, the seat body, the weak structure, the enclosure and the shielding member are configured as an integrally formed structure; and / or the weak structure, the seat body, the enclosure and the shielding member are all configured as plastic parts.

[0019] In some embodiments of the present application, a side of the accommodating space opposite to the seat body is provided as an opening. By providing the opening, the output pole in the accommodating space can be assembled through the opening, so as to fix the output pole to the seat body.

[0020] In some embodiments of the present application, the preset wire-passing area is connected to the opening. The preset wire-passing area is connected to the opening, so that when the shielding member of the preset wire-passing area is destroyed to form a wire-passing hole, the wire-passing hole is also connected to the opening, that is, the wire-passing hole forms a avoidance opening at the opening, and the conductive connector can enter the wire-passing hole from the avoidance opening, thereby improving the convenience of assembling the conductive connector.

[0021] In some embodiments of the present application, the battery device further comprises a protective cover, which is connected to the enclosure portion and covers the opening. The protective cover can shield the opening of the accommodating space, thereby improving the protection performance and the reliability of the battery device.

[0022] In some embodiments of the present application, the protective cover is detachably connected to the enclosure portion. By removing the protective cover, the output pole can be inspected and maintained more conveniently.

[0023] In some embodiments of the present application, the end of the seat body away from the enclosure has an assembly part, the battery cells are arranged in plurality, all the battery cells form at least one battery cell assembly, the battery cell assembly has a plurality of battery cells arranged in sequence, and the battery cell assembly is provided with abutment members at least at one end along the arrangement direction of the plurality of battery cells, and the seat body is provided on the abutment members or the battery cells through the assembly part. By providing the assembly part, the assembly convenience of the output pole mounting seat is improved.

[0024] In some embodiments of the present application, the weak structure of at least one of the preset wire-passing areas is destroyed to form the wire-passing hole; the battery device further includes a conductive connector, one end of which is disposed in the accommodating space and conductively connected to the output pole, and the other end of the conductive connector is disposed through the wire-passing hole. The shielding member is separated from the preset wire-passing area by the damage of the weak structure, and a wire-passing hole is formed in the corresponding preset wire-passing area. During actual assembly, the appropriate preset wire-passing area can be determined to form the wire-passing hole according to the actual routing direction of the conductive connector, which facilitates the assembly of the conductive connector.

[0025] The second aspect of the present application proposes an output pole mounting seat, including a seat body and an enclosure portion, wherein the enclosure portion is connected to the seat body and is arranged together with the seat body to form a accommodating space, and at least one preset wire-passing area is arranged on the enclosure portion, and a shielding member is arranged in each of the preset wire-passing areas, and the shielding member is connected to the enclosure portion and / or the seat body as a whole through a weak structure, and the weak structure in any one of the preset wire-passing areas is arranged to be able to be destroyed, so that the shielding member is separated from the preset wire-passing area to form a wire-passing hole in the preset wire-passing area.

[0026] The output mounting seat of this embodiment has a shielding member in its preset wire passing area, and the shielding member is connected to the seat body and / or the enclosure as a whole through a weak structure. The preset wire passing area where wires need to be passed can be separated from the shielding member in the preset wire passing area to form a wire passing hole by destroying the weak structure, thereby meeting the wire passing requirements of the output pole mounting seat. The output pole mounting seat has a simple structure and is easy to assemble. For the preset wire passing area where no wires need to be passed, the shielding member can be connected to the seat body more stably to shield the preset wire passing area at the corresponding position, thereby reducing the possibility of the shielding member falling off, improving the protective effect of the output pole mounting seat, reducing the risk of electric shock for personnel during assembly, disassembly or after-sales maintenance of the battery device, and improving the reliability of the battery device.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0035] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0036] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of the associated objects, indicating that there may be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone.

[0039] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0040] A battery device is usually provided with an output pole. For example, the battery device may be provided with an output pole for connecting to an external device, through which electric energy may be output to the external device or the battery device may be charged; for another example, multiple battery cells in the battery device may be connected in series or in parallel through the output pole.

[0041] The output pole of the battery device can be supported and fixed by the output pole mounting seat. Considering the protection performance and reliability, the output pole mounting seat is usually surrounded by an accommodation space, and the fixed position of the output pole can be set in the accommodation space. The output pole mounting seat is also provided with a wire hole to facilitate the wiring (copper bar and other conductive connectors) to pass through. When the battery device is wired, in order to save layout space, the same output mounting seat may need to output wires in multiple directions, that is, wire holes need to be set in different directions, or the output directions of output mounting seats in different positions may also be designed to be different. In order to meet the wiring requirements and versatility, in some technologies, when processing the output mounting seat, wire holes will be reserved in multiple directions of the output mounting seat, and then in the process of assembling the battery device, according to the output requirements of the output mounting seat, the wire holes that do not need to be output are blocked with plugs. During the assembly of the battery device, the output mounting base with multiple wire holes reserved is prone to missing plug-in holes at the positions where no wires are required. In addition, during the use of the battery device, the plug-in is easily dropped due to factors such as vibration, resulting in a reduction in the protective effect of the output pole mounting base, affecting the reliability of the battery device and increasing the risk of electric shock to personnel during assembly, disassembly or after-sales maintenance of the battery device.

[0042] Based on the above problems, in order to improve the protective effect of the output pole mounting seat and improve the reliability of the battery device, the present application provides an output pole mounting seat, wherein a shielding member is arranged in the preset wire-passing area of ​​the output pole mounting seat, and the shielding member is connected to the main part of the output pole mounting seat through a weak structure as a whole, and the weak structure is arranged to be damaged, so that the shielding member is separated from the output pole mounting seat to form a wire-passing hole. The preset wire-passing area where wires need to be passed can be destroyed by destroying the weak structure, so that the shielding member is separated from the preset wire-passing area to form a wire-passing hole, thereby meeting the wire-passing requirements of the output pole mounting seat, and the output pole mounting seat has a simple structure and is easy to assemble; and for the preset wire-passing area where wires do not need to be passed, the shielding member can be connected to the seat body more stably to shield the preset wire-passing area at the corresponding position, thereby reducing the possibility of the shielding member falling off, improving the protective effect of the output pole mounting seat, reducing the risk of electric shock to personnel during assembly, disassembly or after-sales maintenance of the battery device, and improving the reliability of the battery device.

[0043] The output pole mounting seat provided in this embodiment can be installed in a battery device to support and fix the output pole of the battery device.

As an example, when the shell 212 is a non-sealed structure, the shell 212 plays a role in protecting the electrode assembly 211, and a sealed bag is also included between the shell 212 and the electrode assembly 211, and the sealed bag is used to encapsulate the electrode assembly 211 and the electrolyte. Specifically, the sealed bag may be a bag-shaped insulating member or an aluminum-plastic film. When the shell 212 is a sealed structure, it is used to encapsulate components such as the electrode assembly 211 and the electrolyte.

[0066] refer to Figure 2 and Figure 3 , and combined with Figures 4 to 8 As shown, Figure 4 This is a schematic diagram of the structure of the output pole mounting seat proposed in some embodiments of the present application. Figure 5 A schematic diagram of an output pole mounting seat from one perspective proposed in some embodiments of the present application, Figure 6 A schematic diagram of another perspective of the output pole mounting seat proposed in some embodiments of the present application, Figure 7 This is a schematic diagram of another perspective of the output pole mounting seat proposed in some embodiments of the present application, Figure 8 Schematic diagram of the output pole mounting seat provided in some embodiments of the present application forming a wire hole on the opposite side of the notch. The present embodiment provides a battery device 10, including a box body 100, a battery cell 210, an output pole mounting seat 300 and an output pole 500. The battery cell 210 is arranged in the box body 100. The output pole mounting seat 300 includes a seat body 310 and a surrounding portion 320. The surrounding portion 320 is connected to the seat body 310 and is surrounded by the seat body 310 to form a accommodating space 330. The surrounding portion 320 is provided with a hole to There is at least one preset line-passing area 323, and a shielding member 340 is arranged in each preset line-passing area 323. The shielding member 340 is connected to the enclosure 320 and / or the seat body 310 as a whole through a weak structure 350. The weak structure 350 is configured to be capable of being destroyed so that the shielding member 340 is separated from the preset line-passing area 323 to form a line-passing hole 360 ​​in the preset line-passing area 323; the output pole 500 is conductively connected to the battery cell 210, and part of the output pole 500 is located in the accommodating space 330 and connected to the seat body 310.

[0067] The number of the battery cell 210 in the battery device 10 of this embodiment may be one or more.

[0068] The output pole 500 is a conductive member, which can be disposed in the high-voltage circuit of the battery device 10. Exemplarily, the output pole 500 can be a copper bar sheet, an aluminum bar sheet, a bar sheet of a copper-aluminum composite material, etc. One or more output poles 500 can be disposed in the battery device 10, and at least one of these output poles 500 corresponds to the output pole mounting seat 300 proposed in the embodiment of the present application.

[0069] Exemplarily, the output pole 500 may be configured as the electrode terminal 216 of the battery cell 210 . For example, the electrode terminal 216 of the battery cell 210 in the battery cell assembly 200 for connecting to other battery cell assemblies 200 or external devices (such as a high voltage box or an external circuit, etc.) may serve as the output pole 500 .

[0070] Exemplarily, the output pole 500 may be configured as a conductive member connected to the electrode terminal 216 of the battery cell 210. For example, the electrode terminal 216 of the battery cell 210 in the battery cell assembly 200 for connecting to other battery cell assemblies 200 or an external device is connected to a conductive member, and the conductive member may serve as the output pole 500. The output pole 500 and the electrode terminal 216 of the battery cell 210 may be directly connected to achieve electrical conduction therebetween; the output pole 500 and the electrode terminal 216 of the battery cell 210 may also be indirectly connected through a busbar to achieve electrical conduction therebetween.

[0071] The output pole 500 can be connected to the conductive connector 600 to achieve the corresponding conductive requirements of the battery device 10. The wire-passing hole 360 ​​formed by the preset wire-passing area 323 is used for the conductive connector 600 to pass through.

[0072] In some embodiments, the output electrode 500 can be used to achieve conductive connection between the battery device 10 and an external device, specifically, Fig. 9 and Fig.10 As shown, Fig. 9 This is a partial simplified schematic diagram of a battery device proposed in some embodiments of the present application. Fig.10 This is a simplified schematic diagram of the connection between the output pole mounting seat, the output pole and the first conductive connector proposed in some embodiments of the present application. The battery cell 210 in the battery device 10 is connected to the conductive connector 600 (refer to the third conductive connector 630) through the output pole 500, and the conductive connector 600 (refer to the third conductive connector 630) can be conductively connected to an external device (i.e., an external circuit).

[0073] In some embodiments, the output pole 500 can also be used to realize a conductive member connected in series or in parallel between multiple battery cell assemblies 200. Fig. 9 , Fig.11 and Fig.12 As shown, Fig.11 This is a schematic diagram of the connection between the output pole mounting seat, the output pole and the second conductive connecting member proposed in some embodiments of the present application. Fig.13 This is a simplified schematic diagram of the connection between the output pole mounting seat, the output pole and the third conductive connector proposed in some embodiments of the present application. Adjacent battery cell assemblies 200 are connected to the conductive connector 600 (refer to the first conductive connector 610 and the second conductive connector 620) through their respective output poles 500 to achieve series or parallel connection.

[0074] The output pole mounting seat 300 is used to support and fix the output pole 500. The output pole mounting seat 300 can be set as an insulating member, which can play the role of insulation and protection for the output pole 500. The output pole mounting seat 300 can be set on the box body 100, and can also be set on the battery cell 210.

[0075] For example, an output pole mounting seat 300 and an output pole 500 may be disposed at the end of the battery cell 210 .

[0076] For example, along the arrangement direction of the plurality of battery cells 210 in the battery cell assembly 200 , the output pole mounting seat 300 and the output pole 500 may be arranged at one end or both ends of the battery cell assembly 200 .

[0077] The seat body 310 and the enclosure 320 can both be provided as insulating parts. The output pole mounting seat 300 can be fixed by the seat body 310 .

[0078] Exemplarily, the seat body 310 may be mounted on the box body 100 to support and fix the output pole mounting seat 300 through the box body 100 . For example, the seat body 310 may be mounted on a side wall of the box body 100 .

[0079] Exemplarily, the seat body 310 may also be installed on the battery cell 210 to support and fix the output pole mounting seat 300 through the battery cell 210 . For example, the seat body 310 may be installed on the ends of the shells 213 of two adjacent battery cells 210 .

[0080] The enclosure 320 can play a protective role, reduce the fixed position of personnel reaching into the output pole 500, and improve the protection level. The enclosure 320 and the seat body 310 can be an integral structure, for example, an integrally formed structure, or a structure assembled and connected into one body.

[0081] Exemplarily, the seat body 310 has a first end surface 311 , and along the circumference of the first end surface 311 , the enclosure portion 320 surrounds at least a portion of the circumferential edge of the first end surface 311 to cooperate with the first end surface 311 to form an accommodating space 330 .

[0082] The output pole 500 can be connected to the seat body 310 so that the output pole 500 is relatively fixed to the output pole mounting seat 300. Exemplarily, the first end surface 311 can be provided with a fixing portion 380, and the output pole 500 is connected to the fixing portion 380 so as to be relatively fixed to the output pole mounting seat 300. Among them, the output pole 500 and the fixing portion 380 (i.e., the seat body 310) can be fastened and connected by a fastener 700 (such as a screw, a bolt, etc.). The fixing portion 380 can be set as one, or it can be set as a plurality of fixed portions arranged at intervals.

[0083] Illustratively, the fixing portion 380 may protrude from the first end surface 311 .

[0084] like Figures 6 to 8 As shown, exemplarily, two fixing parts 380 are provided, and the two fixing parts 380 are provided as locking terminals. Each fixing part 380 may have a threaded hole, and a connecting hole is provided on the output pole 500. A bolt passes through the connecting hole of the output pole 500 and is threadedly connected with the threaded hole of the fixing part 380 to lock and fix the output pole 500.

[0085] The enclosure 320 of the output pole mounting seat 300 may be reserved with a notch 324 to facilitate the electrode terminal 216 (or the current collecting component) to enter the accommodating space 330. It should be noted that in some other implementations, the notch 324 of the output pole mounting seat 300 may also be set as a wire-passing hole 360 ​​formed by the shielding member 340 being separated from the preset wire-passing area 323, that is, the area of ​​the output pole mounting seat 300 for the electrode terminal 216 (or the current collecting component) to enter is also set as the preset wire-passing area 323, and is constructed with a weak structure 350 and a shielding member 340. In the process of assembling the output pole mounting seat 300 with the battery cell 210, the wire-passing hole 360 ​​is formed by destroying the weak structure 350 of the preset wire-passing area 323, and the wire-passing hole 360 ​​can be used as the notch 324 for the output pole 500 to enter the accommodating space 330.

[0086] The preset wire passing area 323 generally refers to the area of ​​the output pole mounting seat 300 that is pre-planned for routing, and these areas may be one or more. During actual assembly, the conductive connector 600 may pass through a suitable preset wire passing area 323 according to the actual requirements of the routing direction. In some special cases, the preset wire passing area 323 also includes the area of ​​the output pole mounting seat 300 for the output pole 500 to pass through.

[0087] It can be understood that, in the actual assembly process, the preset line-passing area 323 where the weak structure 350 is destroyed and the shielding member 340 is detached is the preset line-passing area 323 through which the conductive connector 600 actually passes, that is, the preset line-passing area 323 that forms the line-passing hole 360 ​​is a suitable line-passing area selected according to actual needs for the conductive connector 600 to actually pass through.

[0088] The shielding member 340 is a member for shielding the corresponding preset line passing area 323, which may be a plate or the like. The weak structure 350 may be understood as a structure that is easily damaged. Compared with the enclosure 320 (the structure of the enclosure 320 other than the preset line passing area 323) and the seat body 310, the weak structure 350 has weaker damage resistance, and its bearing capacity, strength or stability is weaker. In some implementations, the weak structure 350 may be a structure that is easily broken.

[0089] Exemplarily, the structure of the circumferential edge of the preset crossing line area 323 may be at least partially thinned to form a weak structure 350 .

[0090] Exemplarily, as shown in the figure, a spacing gap 370 may be provided at the circumferential edge of the preset passing line area 323 so that the circumferential edge of the preset passing line area 323 forms a weak structure 350 .

[0091] Exemplarily, the circumferential edge of the preset passing line area 323 is processed using a material with lower strength than the surrounding portion 320 or the seat body 310 , and these areas of lower strength material form a weak structure 350 .

[0092] The shielding member 340 is separated from the preset wire passing area 323 to form the wire passing hole 360 ​​, which can be understood as the shielding member 340 is separated from the output pole mounting seat 300 , so that the wire passing hole 360 ​​is formed at the original position of the shielding member 340 .

[0093] The shielding member 340 can be set to the same strength as the weak structure 350. When the weak structure 350 is destroyed, the shielding member 340 can be destroyed together and separated from the preset line-crossing area 323. The shielding member 340 can also be set to a member with greater strength than the weak structure 350. When the weak structure 350 is destroyed, the shielding member 340 can be separated from the seat body 310 or the enclosure 320 through the destroyed position of the weak structure 350, thereby separating from the preset line-crossing area 323.

[0094] Optionally, in some implementations, along the arrangement direction of the seat body 310 and the enclosure portion 320 (refer to the third direction Z), each preset passing line area 323 can be located on the inner side of the edge of the enclosure portion 320. At this time, the shielding member 340 can be connected to the enclosure portion 320 only through the weak structure 350.

[0095] Optionally, in other implementations, along the arrangement direction of the seat body 310 and the enclosure 320 (refer to the third direction Z), each preset line-passing area 323 may also extend from the first end surface 311 to the enclosure 320. Exemplarily, the preset line-passing area 323 may pass through both ends of the enclosure 320. At this time, at least one of the first end surface 311 and the enclosure 320 may be connected to the shielding member 340 through the weak structure 350.

[0096] The shielding member 340 , the weak structure 350 , and the seat body 310 and / or the enclosure 320 connected to the weak structure 350 may be an integrally formed structure, or may be an integrally assembled structure during the production process of the output pole mounting seat 300 .

[0097] It should be noted that the “integrated” involved in this embodiment generally refers to a structure that cannot be separated without being destroyed, and specifically may include a non-detachable structure such as integrally formed or welded together.

[0098] In this embodiment, the preset wire-passing area 323 of the output pole mounting seat 300 is provided with a shielding member 340, and the shielding member 340 is connected to the seat body 310 and / or the enclosure 320 as a whole through a weak structure 350. The preset wire-passing area 323 where wires need to be passed can be separated from the preset wire-passing area 323 by destroying the weak structure 350 to form a wire-passing hole 360, thereby meeting the wire-passing demand of the output pole mounting seat 300. The output pole mounting seat 300 has a simple structure and is easy to assemble. For the preset wire-passing area 323 where no wires need to be passed, the shielding member 340 can be connected to the seat body 310 more stably to shield the preset wire-passing area 323 at the corresponding position, thereby reducing the possibility of the shielding member 340 falling off, improving the protective effect of the output pole mounting seat 300, reducing the risk of electric shock for personnel during assembly, disassembly or after-sales maintenance of the battery device 10, and improving the reliability of the battery device 10.

[0099] According to some embodiments of the present application, optionally, Figures 4 to 7 As shown, the enclosure portion 320 is provided with at least two preset crossing line areas 323 facing different directions.

[0100] The enclosure 320 is provided with at least two preset wire passing areas 323 facing different directions. It can be understood that the enclosure 320 is provided with at least two preset wire passing areas 323 facing different directions, that is, at least two preset wire passing areas 323 are located on different sides of the enclosure 320. The preset wire passing areas 323 facing different directions can form wire passing holes 360 in different directions, so that the output pole mounting seat 300 can lead out wires in different directions (leading out means that the conductive connector 600 extends out).

[0101] By setting preset wire passing areas 323 with different orientations, the output pole mounting seat 300 can be destroyed by the weak structure 350 to form different wire output directions. In this way, a suitable preset wire passing area 323 can be selected as needed to form a wire passing hole 360, thereby improving the convenience of arranging the conductive connector 600 and simplifying the wiring space.

[0102] According to some embodiments of the present application, optionally, Figures 4 to 7 As shown, the enclosure 320 includes a first sub-enclosure 321 and two second sub-enclosures 322. The two second sub-enclosures 322 are arranged opposite to each other, the first sub-enclosure 321 is connected between the two second sub-enclosures 322, and at least two of the first sub-enclosure 321 and the two second sub-enclosures 322 are provided with a preset crossing line area 323.

[0103] The first sub-enclosure 321 and the two second sub-enclosures 322 are respectively arranged on three sides of the accommodating space 330, and the first sub-enclosure 321 and the two second sub-enclosures 322 are respectively local structures of the enclosure 320. Exemplarily, the enclosure 320 can be roughly a rectangular frame structure, and the first sub-enclosure 321 and the two second sub-enclosures 322 can be respectively understood as a side wall of the rectangular frame structure, wherein the two second sub-enclosures 322 constitute two opposite side walls of the rectangular frame structure, and the first sub-enclosure 321 is one of the side walls connected between the two second sub-enclosures 322.

[0104] Exemplarily, the first sub-enclosure portion 321 may be provided with a preset line-crossing area 323 , and one of the two second sub-enclosure portions 322 may be provided with a preset line-crossing area 323 .

[0105] Exemplarily, the two second sub-enclosure portions 322 are respectively provided with preset crossing line areas 323 .

[0106] Exemplarily, the first sub-enclosure portion 321 may be provided with a preset line-crossing area 323 , and the two second sub-enclosure portions 322 may be provided with preset line-crossing areas 323 , respectively.

[0107] The first sub-enclosure 321 and the two second sub-enclosures 322 face different directions respectively, and at least two of the first sub-enclosure 321 and the two second sub-enclosures 322 are provided with preset wire passing areas 323, so that the output pole mounting seat 300 can be destroyed by the weak structure 350 to form different wire output directions. In this way, a suitable preset wire passing area 323 can be selected as needed to form a wire passing hole 360, which improves the convenience of arranging the conductive connector 600 and helps to simplify the wiring space.

[0108] According to some embodiments of the present application, optionally, Figures 4 to 7 As shown, the enclosure portion 320 is provided with a notch 324 . The output pole 500 is passed through the notch 324 .

[0109] The output pole 500 passes through the notch 324 and enters the accommodating space 330, thereby connecting with the seat body 310. The notch 324 can be an integrally formed structure during the molding process of the enclosure 320, or can be a hollow structure formed by later processing.

[0110] Exemplarily, the notch 324 is disposed on the opposite side of the first sub-enclosing portion 321 .

[0111] Exemplarily, along the arrangement direction of the seat body 310 and the enclosure portion 320 (refer to the third direction Z), the notch 324 starts from the first end surface 311 of the seat body 310 and passes through both ends of the enclosure portion 320 .

[0112] When the output pole mounting base 300 is assembled into the battery device 10 , the notch 324 can be disposed corresponding to the output pole 500 .

[0113] The notch 324 is provided to facilitate the output pole 500 to enter the accommodating space 330 , thereby improving the convenience of assembling the output pole 500 and the output pole mounting seat 300 .

[0114] According to some embodiments of the present application, optionally, Figures 4 to 7 As shown, there is a spacing gap 370 between the partial shielding member 340 and the enclosing portion 320 and / or the seat body 310 that encloses the preset passing line area 323 , and the weak structure 350 and the spacing gap 370 are arranged along the circumference of the preset passing line area 323 .

[0115] In some embodiments, along the arrangement direction of the seat body 310 and the enclosure portion 320 (refer to the third direction Z), each preset passing line area 323 can be located on the inner side of the edge of the enclosure portion 320, that is, the preset passing line area 323 is formed by the enclosure portion 320, and a spacing gap 370 is partially set between the shielding member 340 and the enclosure portion 320, and the connection position between the shielding member 340 and the enclosure portion 320 forms a weak structure 350.

[0116] like Figures 4 to 7 As shown, along the arrangement direction of the seat body 310 and the enclosure portion 320 (refer to the third direction Z), the preset line-passing area 323 can extend from the first end surface 311 to the enclosure portion 320. For example, the preset line-passing area 323 can pass through both ends of the enclosure portion 320, and a spacing gap 370 is set between the edge of the shielding member 340 facing the enclosure portion 320 (refer to the second side 342 and the fourth side 344) and the enclosure portion 320, so that the portion between the shielding member 340 and the enclosure portion 320 is not too large. The shielding member 340 is arranged at intervals, with a spacing gap 370 between the edge of the seat body 310 (refer to the third side 343) and the seat body 310 (i.e., the first end face 311), so that the shielding member 340 and the seat body 310 (i.e., the first end face 311) are partially spaced apart, so that a weak structure 350 can be formed at the connection position between the shielding member 340 and the enclosure 320 and the connection position between the shielding member 340 and the seat body 310 (i.e., the first end face 311).

[0117] Along the circumference of the preset crossing line area 323 , one or more weak structures 350 may be provided, and one or more spacing gaps 370 may be provided.

[0118] By providing the spacing gap 370 , the convenience of the weak structure 350 being destroyed by external force can be improved. When the weak structure 350 is destroyed, the shielding member 340 can be easily separated from the preset wire passing area 323 to form the wire passing hole 360 ​​, which is easy to operate.

[0119] According to some embodiments of the present application, optionally, Figures 4 to 7 As shown, the spacing gaps 370 include at least two, and along the circumference of the preset crossing area 323, the spacing gaps 370 and the weak structures 350 are alternately arranged.

[0120] That is to say, both sides of any weak structure 350 are provided with spacing gaps 370 , and weak structures 350 are provided between connected spacing gaps 370 .

[0121] By arranging the spacing gaps 370 and the weak structures 350 alternately, the convenience of the weak structures 350 being destroyed by external forces can be improved. When the weak structures 350 are destroyed, the shielding member 340 can be easily separated from the preset wire passing area 323 to form the wire passing hole 360, which is easy to operate.

[0122] According to some embodiments of the present application, optionally, along the circumference of the preset crossing area 323 , the size of the weak structure 350 is smaller than the size of the spacing gap 370 .

[0123] The size of the weak structure 350 may be the total size of all the weak structures 350 along the circumference of the preset cross-line area 323 , and the size of the spacing gaps 370 may be the total size of all the spacing gaps 370 along the circumference of the preset cross-line area 323 .

[0124] The size of the weak structure 350 is smaller than the size of the spacing gap 370 , that is, the edge area of ​​the shielding member 340 connected by the weak structure 350 is smaller than the size of the spacing area between the shielding member 340 and the seat body 310 or the surrounding portion 320 .

[0125] By making the size of the weak structure 350 smaller than the size of the spacing gap 370, the convenience of the weak structure 350 being destroyed by external force can be improved. When the weak structure 350 is destroyed, the shielding member 340 can be easily separated from the preset wire passing area 323 to form the wire passing hole 360, which is easy to operate.

[0126] According to some embodiments of the present application, optionally, Figures 4 to 7 As shown, the shielding member 340 includes a first side 341 , a second side 342 , a third side 343 and a fourth side 344 connected in sequence end to end, and at least one of the first side 341 , the second side 342 , the third side 343 and the fourth side 344 is connected to a weak structure 350 .

[0127] That is, at least one side of the shielding member 340 is connected to the enclosure portion 320 or the seat body 310 through the weak structure 350. Each side may be connected to one or more weak structures 350.

[0128] Exemplarily, the preset crossing line area 323 is roughly rectangular, the shielding member 340 can be a roughly rectangular plate, and the four sides of the shielding member 340 are respectively a first side 341, a second side 342, a third side 343 and a fourth side 344.

[0129] At least one of the circumferential sides of the shielding member 340 is provided with a weakening structure 350 , which has a simple structure and is easy to process.

[0130] According to some embodiments of the present application, optionally, Figures 4 to 7 As shown, at least one of the first side 341 , the second side 342 , the third side 343 and the fourth side 344 is provided with a weak structure 350 in the middle portion along the extension direction thereof.

[0131] The middle portion of the first side 341 along its own extension direction refers to the area between the two ends of the first side 341 , and specifically may be the midpoint of the first side 341 along its own extension direction and partial areas on both sides of the midpoint.

[0132] The middle parts of the second side 342 , the third side 343 and the fourth side 344 along their respective extension directions can refer to the explanation of the middle part of the first side 341 , and will not be repeated here.

[0133] The weak structure 350 is connected to the middle of the side, which improves the stability of the shielding member 340 being fixed by the weak structure 350 .

[0134] According to some embodiments of the present application, optionally, Figures 4 to 7 As shown, in a specific implementation, along the arrangement direction of the seat body 310 and the enclosure portion 320, a preset passing line area 323 passes through one end of the enclosure portion 320 toward the seat body 310; the second side 342 and the fourth side 344 are arranged opposite to each other, and extend respectively along the arrangement direction of the seat body 310 and the enclosure portion 320, the third side 343 is located at one end of the shielding member 340 toward the seat body 310, and a weakening structure 350 is respectively arranged between the second side 342 and the fourth side 344 and the enclosure portion 320, and a weakening structure 350 is arranged between the third side 343 and the seat body 310.

[0135] Among them, the preset wire-passing area 323 passes through the end of the enclosure 320 toward the seat body 310, which can be understood as that, along the arrangement direction of the seat body 310 and the enclosure 320, the preset wire-passing area 323 extends from the first end surface 311 to the enclosure 320, and the first blocking surface is surrounded by the preset wire-passing area 323. The preset wire-passing area 323 passes through the end of the enclosure 320 toward the seat body 310, which facilitates the processing of the preset wire-passing area 323, and enables the preset wire-passing area 323 to form a wire-passing hole 360 ​​that passes through the enclosure 320 toward the end of the seat body 310, which facilitates the routing of the conductive connector 600.

[0136] By arranging the weak structure 350 in the middle of the three sides of the shielding member 340 , the stability of the shielding member 340 being fixed by the weak structure 350 is improved.

[0137] According to some embodiments of the present application, optionally, reference Figures 4 to 8 The weak structure 350 includes a first weak structure 351, and the first weak structure 351 is disposed at one end of the shielding member 340 facing the seat body 310. Along the arrangement direction from the shielding member 340 to the seat body 310, the destruction position of the first weak structure 351 is disposed closer to the seat body 310 than the output pole 500 located in the accommodating space 330, or the destruction position of the first weak structure 351 is disposed flush with the output pole 500 located in the accommodating space 330.

[0138] The destruction position of the first weak structure 351 refers to the destruction position when the first weak structure 351 is destroyed so that the shielding member 340 is separated from the preset crossing line area 323 .

[0139] For example, a weak portion may be provided on the weak structure 350, and the weak portion forms the destruction position of the weak structure 350. The weak portion is easier to be destroyed than other positions of the weak structure 350, and the weak portion may be a region where the weak structure 350 is locally thinned. For example, the weak structure 350 may be provided with a notch, and the region where the notch is located forms the weak portion. By providing the weak portion, the destruction position of the weak structure 350 can be better located.

[0140] The destruction position of the first weak structure 351 is arranged closer to the seat body 310 than the output pole 500 located in the accommodating space 330, or the destruction position of the first weak structure 351 is arranged flush with the output pole 500 located in the accommodating space 330. It can be understood that when the first weak structure 351 is destroyed to cause the shielding member 340 to detach from the preset passing line area 323 to form the passing line hole 360, the residual structure of the first weak structure 351 on the enclosure 320 or the seat body 310 does not exceed the position of the output pole 500.

[0141] It is understandable that the side of the output pole 500 away from the seat body 310 can be used to connect with the conductive connector, and after the first weak structure 351 is damaged, the highest point of the residual structure is not higher than the lowest point of the side of the output pole 500 away from the seat body 310. After the first weak structure 351 is damaged, its residual structure is lower than the output pole 500 or is arranged flush with the output pole 500, which can reduce the risk of interference between the residual structure and the conductive connector 600, resulting in the conductive connector 600 being lifted up, and the connection area between the conductive connector 600 and the output pole 500 being reduced, thereby causing abnormal temperature rise, thereby improving the reliability of the battery device 10.

[0142] According to some embodiments of the present application, optionally, reference Figures 4 to 8 , and combined with Fig.13 As shown, Fig.13 This is a cross-sectional schematic diagram of the connection between the output pole mounting seat 300, the conductive connector 600 and the output pole 500 proposed in some embodiments of the present application, wherein the surface of the seat body 310 facing the accommodating space 330 is the first end surface 311, and a fixing portion 380 is provided on the first end surface 311, and the fixing portion 380 has a supporting surface 381, and the output pole 500 is fixed to the supporting surface 381; the destruction position of the first weak structure 351 is arranged closer to the seat body 310 than the supporting surface 381, or the destruction position of the first weak structure 351 is arranged flush with the supporting surface 381.

[0143] The destruction position of the first weak structure 351 is arranged closer to the seat body 310 than the support surface 381, or the destruction position of the first weak structure 351 is arranged flush with the support surface 381. It can be understood that when the first weak structure 351 is destroyed to cause the shielding member 340 to separate from the preset passing line area 323 to form the passing line hole 360, the residual structure of the first weak structure 351 on the enclosure 320 or the seat body 310 does not exceed the fixed height of the output pole 500.

[0144] Exemplarily, the first weak structure 351 can break from the end facing away from the shielding member 340, that is, the damage position of the first weak structure 351 is located at the end facing away from the shielding member 340 (the end connected to the seat body 310 can be referred to), and the end of the first weak structure 351 facing away from the shielding member 340 is located on the bottom side of the support surface 381 or is flush with the support surface 381.

[0145] Exemplarily, one end of the first weak structure 351 connected to the shielding member 340 is lower than the support surface 381 or flush with the support surface 381, so that the first weak structure 351 is located as a whole on the bottom side of the support surface 381. In this way, no matter where the first weak structure 351 is damaged, its residual structure will not exceed the height of the support surface 381.

[0146] After the first weak structure 351 of the present embodiment is damaged, its residual structure is lower than the support surface 381 or flush with the support surface 381, and the output pole 500 is not easy to interfere with the residual structure, thereby reducing the possibility of the output pole 500 being supported by the residual structure and tilting, improving the fixing stability and connection reliability between the output pole 500 and the seat body 310, reducing the risk of poor contact or ablation caused by the output pole 500, and improving the reliability of the battery device 10. According to some embodiments of the present application, optionally, Figures 4 to 7As shown, along the arrangement direction of the seat body 310 and the enclosure portion 320, a preset passing line area 323 passes through the enclosure portion 320 toward one end of the seat body 310, the first weak structure 351 is connected to the first end face 311, and the support surface 381 protrudes relative to the first end face 311 toward the enclosure portion 320. The first weak structure 351 extends from the first end face 311 toward the enclosure portion 320, so that the first weak structure 351 forms an easily damaged position at the connection with the first end face 311. Since the support surface 381 protrudes relative to the first end face 311, the easily damaged position is lower than the support surface 381. In this way, when the first weak structure 351 is damaged, it is easier to ensure that the remaining structure does not exceed the height of the support surface 381, thereby improving the convenience of the first weak structure 351 being damaged to form the wire hole 360.

[0147] It should be noted that, when other weak structures 350 except the first weak structure 351 are provided, the corresponding wire holes 360 should be formed to allow the conductive connector 600 to pass through.

[0148] According to some embodiments of the present application, optionally, the seat body 310, the weak structure 350, the enclosure 320 and the shielding member 340 are set as an integrally molded structure; and / or the weak structure 350, the seat body 310, the enclosure 320 and the shielding member 340 are all set as plastic parts.

[0149] The seat body 310 , the weak structure 350 , the enclosure 320 and the shielding member 340 may be configured as an integrally-molded structure by injection molding, that is, the output pole mounting seat 300 may be integrally-molded by injection molding.

[0150] The weak structure 350 , the seat body 310 , the enclosure portion 320 , and the shielding member 340 may be plastic members made of the same material, or may be plastic members made of different materials.

[0151] The output pole mounting seat 300 of this embodiment is easy to obtain materials, has low cost, and is easy to process.

[0152] According to some embodiments of the present application, optionally, Figures 4 to 8 As shown, a side of the accommodating space 330 opposite to the seat body 310 is configured as an opening 325 .

[0153] The opening 325 is in communication with the accommodation space 330 . By providing the opening 325 , the output pole 500 in the accommodation space 330 can be assembled through the opening 325 , so as to fix the output pole 500 to the seat body 310 .

[0154] According to some embodiments of the present application, optionally, the preset line-passing area 323 is connected to the opening 325 .

[0155] That is to say, along the arrangement direction of the seat body 310 and the enclosure 320 (refer to the third direction Z), the preset line area 323 passes through one end of the enclosure 320 toward the opening 325 , and the preset line area 323 extends from the opening 325 to the enclosure 320 .

[0156] The preset wire-passing area 323 is connected with the opening 325, so that when the shielding member 340 of the preset wire-passing area 323 is destroyed to form the wire-passing hole 360, the wire-passing hole 360 ​​is also connected with the opening 325, that is, the wire-passing hole 360 ​​forms an avoidance opening at the opening 325, and the conductive connector 600 can enter the wire-passing hole 360 ​​from the avoidance opening, thereby improving the assembly convenience of the conductive connector 600.

[0157] It should be noted that, in some embodiments, the gap 324 through which the output pole 500 passes may also be connected to the opening 325 , so as to improve the assembly convenience of the output pole 500 .

[0158] According to some embodiments of the present application, optionally, Fig.14 As shown, Fig.14 The schematic diagram of the structure of the output pole mounting seat and the protective cover assembly proposed in some embodiments of the present application, the battery device 10 further includes a protective cover 400. The protective cover 400 is connected to the enclosure 320 and covers the opening 325 in an openable and closable manner.

[0159] The protective cover 400 may be an insulating member, and specifically may be a plastic member.

[0160] Exemplarily, the protective cover 400 can be arranged on the opening 325 in a manner that allows it to be opened and closed. For example, the protective cover 400 can be detachably connected to the enclosure 320, and the opening 325 can be opened by removing the protective cover 400. For another example, the protective cover 400 can be connected to the enclosure 320 by being hinged at one end and snapped at the other end, and the opening 325 can be opened and closed by rotating the protective cover 400 around the hinged end.

[0161] After the output pole 500, the conductive connector 600 and the output pole mounting seat 300 are assembled, the protective cover 400 can be assembled to the protective part to cover the opening 325. The protective cover 400 can cover the opening 325 of the accommodating space 330, thereby improving the protection performance and the reliability of the battery device 10.

[0162] According to some embodiments of the present application, optionally, the protective cover 400 and the enclosure 320 are configured to be detachably connected.

[0163] The protective cover 400 and the protective part can be connected by snapping components, or fastened by fasteners such as bolts.

[0164] In some implementations, the protective cover 400 is snap-fitted to the enclosure 320. Fig.14 As shown, the protective cover 400 is exemplarily provided with a claw 410, and the enclosure 320 is provided with a slot 326, and the claw 410 and the slot 326 are engaged with each other to fix the protective cover 400. Among them, the claw 410 and the slot 326 can be set to a plurality of groups corresponding to each other, and the slot 326 can be set on the inner side of the enclosure 320 (the side facing the accommodating space 330 is the inner side), and the claw 410 penetrates into the accommodating space 330 and engages with the slot 326. The protective cover 400 is engaged with the enclosure 320, and the structure is simple, and it is easy to assemble and disassemble.

[0165] The protective cover 400 is detachable, and the output pole 500 can be inspected and maintained more conveniently by removing the protective cover 400 .

[0166] According to some embodiments of the present application, optionally, Figures 4 to 8 , and combined with Fig.14 and Fig.15 As shown, the end of the seat body 310 away from the enclosure portion 320 has an assembly portion 390. Fig.15 A partial cross-sectional view of a battery cell assembly proposed in some embodiments of the present application. A plurality of battery cells 210 are provided, and all of the battery cells 210 form at least one battery cell assembly 200. The battery cell assembly 200 has a plurality of battery cells 210 arranged in sequence, and a support member 800 is provided at least at one end of the battery cell assembly 200 along the arrangement direction Y1 of the plurality of battery cells 210 thereof, and the seat body 310 is provided on the support member 800 or the battery cell 210 through the assembly portion 390.

[0167] That is to say, the seat body 310 can be installed on the battery cell 210 or on the abutting member 800 .

[0168] Among them, the abutment member 800 refers to a structural member that is arranged at the end of the battery cell assembly 200 (one end or both ends along the arrangement direction Y1 of the multiple battery cells 210 constituting the battery cell assembly), and limits the relative movement of the multiple battery cells 210 at the end of the battery cell assembly 200, so that the multiple battery cells 210 form a relatively fixed whole (i.e., the battery cell assembly 200).

[0169] Exemplarily, the abutment member 800 may be an end plate disposed in the box body 100, and the end plate is disposed at both ends of the plurality of battery cells 210 along the arrangement direction Y1. A fixing belt may be bundled between the end plates at both ends, and the fixing belt cooperates with the end plate to relatively fix the plurality of battery cells 210 in the arrangement direction Y1, so that the plurality of battery cells 210 form a battery cell assembly 200 (which can be understood by referring to a battery module).

[0170] Exemplarily, the abutment member 800 can also be configured as a box structure, and multiple battery cells 210 are arranged in sequence in the box structure and relatively fixed through the box structure to form a battery cell assembly 200 (which can be understood by referring to a battery module). The box structure can serve as an abutment member and can be fixed in the box 100 of the battery device 10.

[0171] For example, the assembly portion 390 may be connected to the housing 212 of the battery cell 210 or the abutment member 800 via a fastener, or may be configured to be snap-fitted.

[0172] Exemplarily, a mounting groove may be provided on the abutment member 800, and the assembly portion 390 may be clamped and fixed in the mounting groove, wherein the outer periphery of the assembly portion 390 may be provided with a clamping protrusion 391, and the clamping protrusion 391 may be in interference fit with the groove wall of the mounting groove.

[0173] By providing the assembly portion 390 , the assembly convenience of the output pole mounting seat 300 is improved.

[0174] According to some embodiments of the present application, optionally, a weak structure 350 of at least one preset wire-passing area 323 is destroyed to form a wire-passing hole 360; the battery device 10 also includes a conductive connector 600, one end of which is disposed in the accommodating space 330 and conductively connected to the output pole 500, and the other end of the conductive connector 600 is disposed to pass through the wire-passing hole 360.

[0175] The other end of the conductive connector 600 can be connected to other output poles 500 or external devices after passing through the wire hole 360. The conductive connector 600 can be a copper bar, an aluminum bar, a copper-aluminum composite conductive sheet, etc.

[0176] By damaging the weak structure 350, the shielding member 340 is separated from the preset wire passing area 323, and a wire passing hole 360 ​​is formed in the corresponding preset wire passing area 323. During actual assembly, the appropriate preset wire passing area 323 for forming the wire passing hole 360 ​​can be determined according to the actual routing direction of the conductive connector 600, thereby facilitating the assembly of the conductive connector 600.

[0177] For example, Fig. 9 As shown, in some embodiments, the battery device 10 includes a plurality of battery cell assemblies 200 (the battery cell assembly 200 can be understood with reference to the battery module, and each battery cell assembly 200 can include a plurality of battery cells 210 arranged along the second direction Y), and the plurality of battery cell assemblies 200 are arranged in two rows along the second direction Y, and each row of battery cell assemblies 200 includes a plurality of battery cell assemblies 200 arranged in sequence along the first direction X.

Fig. 9 and Fig.12 As shown, along the first direction X, the battery cell assemblies 200 located at both ends are respectively provided with output poles 500 and output pole mounting seats 300; wherein, the output poles 500 of the two battery cell assemblies 200 located at the left end of the first direction X and adjacent to each other along the second direction Y can be connected by a third conductive connector 630, so as to connect the two battery cell assemblies 200 in series or in parallel, the notches 324 of the two output pole mounting seats 300 located at the left end are arranged away from each other, and the weak structure 350 of the preset wire passing area 323 (the preset wire passing area 323 is also the preset wire passing area 323 directly facing the notch 324) of the two output pole mounting seats 300 facing each other is destroyed to form a wire passing hole 360, and the third conductive connector 630 passes through the wire passing holes 360 of the two output pole mounting seats 300 on the left side to connect with the corresponding output pole 500. As shown Fig. 9 and Fig.10 As shown, the output poles 500 (one is the positive pole and the other is the negative pole) of the two battery cell assemblies 200 located at the right end of the first direction X and adjacent to each other along the second direction Y are respectively connected with the first conductive connector 610, and the notch 324 of the output pole mounting seat 300 is arranged opposite to the preset wire-passing area 323 forming the wire-passing hole 360, and the first conductive connector 610 is used to connect with the high-voltage box.

[0178] like Fig.13 As shown, the conductive connector 600 and the output pole 500 can be stacked and fixed to the output pole mounting seat 300 by the same fastener 700. At this time, under the pressing action of the fastener 700, the conductive connection between the conductive connector 600 and the output pole 500 can be achieved.

[0179] Some embodiments of the present application also provide an output pole mounting seat 300, including a seat body 310 and an enclosure portion 320, wherein the enclosure portion 320 is connected to the seat body 310 and is arranged together with the seat body 310 to form a accommodating space 330, and at least one preset wire-passing area 323 is arranged on the enclosure portion 320, and each preset wire-passing area 323 is provided with a shielding member 340, and the shielding member 340 is connected to the enclosure portion 320 and / or the seat body 310 as a whole through a weak structure 350, and the weak structure 350 in any preset wire-passing area 323 is arranged to be able to be destroyed, so that the shielding member 340 is separated from the preset wire-passing area 323, so as to form a wire-passing hole 360 ​​in the preset wire-passing area 323.

[0180] The output pole mounting seat 300 of this embodiment may be the output pole mounting seat 300 of the battery device 10 proposed in this application or any embodiment of this application.

[0181] The preset wire-passing area 323 of the output pole mounting seat 300 is provided with a shielding member 340, and the shielding member 340 is connected to the seat body 310 and / or the enclosure 320 as a whole through a weak structure 350. The preset wire-passing area 323 where wires need to be passed can be separated from the preset wire-passing area 323 by destroying the weak structure 350 to form a wire-passing hole 360, thereby meeting the wire-passing requirements of the output pole mounting seat 300. The output pole mounting seat 300 has a simple structure and is easy to assemble. For the preset wire-passing area 323 where wires do not need to be passed, the shielding member 340 can be relatively stably connected to the seat body 310 to shield the preset wire-passing area 323 at the corresponding position, thereby reducing the possibility of the shielding member 340 falling off, improving the protective effect of the output pole mounting seat 300, reducing the risk of electric shock to personnel during assembly, disassembly or after-sales maintenance of the battery device 10, and improving the reliability of the battery device 10.
