Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to battery devices and electrical equipment. Background Art

[0002] As the power and range requirements of new energy vehicles continue to increase, the demands on the high-voltage connectors of power batteries are also increasing. For example, these connectors must withstand complex operating conditions such as vehicle vibration, impact, and temperature fluctuations. However, due to the limitations of traditional protective structure design, the protective position of high-voltage connectors is limited, which affects the spatial arrangement of high-voltage connectors. Utility Model Content

[0003] Based on this, it is necessary to provide a battery device and electrical equipment to reduce restrictions on the protective position of the connector and facilitate the spatial arrangement of the connector.

[0004] In the first aspect, the present application provides a battery device, which includes: a box body; a connecting member, which is at least partially located in the box body; a protective structure, including a fixing component and a protective component connected to the fixing component, and the fixing component is fixed in the box body; the protective component includes a base and a first protective member and a second protective member arranged at intervals on the base along a first direction, the side of the base facing away from the first protective member is connected to the fixing member, the end of the first protective member away from the base and the end of the second protective member away from the base are open ends, and part of the connecting member is arranged between the first protective member and the second protective member.

[0005] When the above-mentioned battery device is arranged in the box, the connector can be inserted between the first protective member and the second protective member, so that the connector is protected between the first protective member and the second protective member. The connector protected between the first protective member and the second protective member can be fixed in the box by a fixing assembly. This can reduce the risks of collision interference between the connector and other structures, wear of the insulating layer, etc., and provide effective protection. Since the connector is located between the first protective member and the second protective member and is fixed in the box by the fixing assembly on the base, the connector does not need to be attached to the side wall of the box for protection and fixation, which effectively reduces the restrictions on the protection position and facilitates the spatial arrangement of the connector in the box.

[0006] In some embodiments, the protective assembly further comprises an elastomer, which is attached to at least one of the two facing sides of the first and second protective members. This design leverages the elasticity of the elastomer to accommodate connectors of varying sizes, effectively improving the suitability of connector protection. It also isolates the connector from direct contact with the first or second protective member, reducing friction and providing effective cushioning.

[0007] In some embodiments, the protective assembly further includes a spacer, and the number of connecting members is at least two, with the spacer interposed between two adjacent connecting members. This design allows each connecting member to be stably confined between the first and second protective members, while also reducing friction between the connecting members and providing effective protection between the connecting members.

[0008] In some embodiments, the battery device further includes a support beam disposed within the housing, and the fixing assembly is fixed to the support beam. This design allows the fixing assembly to be fixed to the support beam, facilitating the distribution of the connectors on the support beam.

[0009] In some embodiments, the fixing assembly includes two stoppers and a locking member. The two stoppers are spaced apart on the side of the base facing away from the first protective member and are located on either side of the support beam along its thickness direction. The locking member is provided on at least one of the stoppers and fixed to the support beam, with the first direction intersecting the thickness direction of the support beam. This design, with the two stoppers positioned on either side of the support beam, facilitates stable attachment of the fixing assembly to the support beam, improving structural stability. Furthermore, intersecting the first direction with the thickness direction of the support beam facilitates easier passage of the connector through the top of the support beam, resulting in a more rational distribution of the connectors.

[0010] In some embodiments, the fixing assembly further includes a positioning protrusion, the locking member and the positioning protrusion are respectively provided on the two limiting members, and the positioning protrusions cooperate with the positioning holes on the support beam. This design, incorporating the positioning protrusions and the positioning holes, facilitates the stable positioning of the fixing assembly on the support beam.

[0011] In some embodiments, each stopper can be rotated or bent relative to the base in a direction that moves the two stoppers toward or away from each other. This design, in which the stopper is an adjustable structure, allows the stopper to better adapt to the side of the support beam, thereby better securing the stopper to the support beam and improving installation stability.

[0012] In some embodiments, a groove is provided at the top of the support beam along its height, extending through the thickness of the support beam, with at least a portion of the protective assembly located within the groove. This design facilitates efficient routing of connectors along the support beam, while also utilizing the first and second protective elements to minimize contact between the connector and the inner wall of the groove, thereby achieving effective protection.

[0013] In some embodiments, the battery assembly includes a restraint assembly, which is provided on the first and / or second protective members, and to which a number of connectors are secured. With this design, the restraint assembly allows a certain number of connectors to pass between the first and second protective members. The restraint assembly can be used to provide fixed points for routing additional connectors, thereby increasing flexibility in routing the various connectors and facilitating optimized layout of the connectors within the housing.

[0014] In some embodiments, the restraint assembly includes a mounting member and a restraint member connected to the mounting member. The mounting member is detachably connected to the first protective member and / or the second protective member, and the restraint member is used to bind a portion of the connecting member. This design ensures that the mounting member and the restraint member stably restrain the portion of the connecting member to the protective structure.

[0015] In some embodiments, the mounting member includes a mounting protrusion and a sleeve portion that sleeves onto the first guard member and / or the second guard member. The mounting protrusion is provided at at least one end of the sleeve portion along the second direction and extends in the second direction. The mounting protrusion is provided with a mounting groove on a surface facing the connector, and the restraining member is at least partially disposed within the mounting groove. The second direction is the length of the connector between the first guard member and the second guard member. This design, with the introduction of the mounting protrusion and the mounting groove, can reduce the space occupied by the restraining member between the first and second guard members, as well as the installation height along the first direction, thereby facilitating better arrangement of the connector.

[0016] In some embodiments, the bottom surface of the mounting protrusion facing the base includes a relief surface, which is inclined relative to the second direction, and the spacing between the relief surface and the base gradually increases from the end of the relief surface closest to the sleeve portion to the end of the relief surface farther from the sleeve portion. This design increases the space at the bottom of the mounting protrusion as it moves away from the sleeve portion, which helps reduce the space occupied by the protective structure in the second direction.

[0017] In a second aspect, the present application provides an electrical device, which includes any one of the battery devices described above. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, "plurality" means at least two, for example, two, three, etc., unless otherwise specifically defined.

[0034] In this application, unless otherwise specified or limited, the terms "mounted," "connected," "connected," "fixed," etc., should be interpreted broadly. For example, these terms may refer to fixed connections, removable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; and internal communication between two components or interaction between two components, unless otherwise specified. Those skilled in the art will understand the specific meanings of these terms in this application based on the specific circumstances.

[0035] In this application, unless otherwise expressly specified or limited, if a first feature is described as being "above" or "below" a second feature, or similar descriptions, this may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0036] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. If an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only embodiment.

[0037] Currently, market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric vehicles, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0038] With the continuous improvement of the power and mileage requirements of new energy vehicles, the requirements for the high-voltage connectors of power batteries have increased accordingly. For example, the high-voltage connectors of power batteries need to withstand complex working conditions such as vehicle vibration, impact and temperature changes. In order to reduce the risks of collision and interference between high-voltage connectors and other structures, wear of the insulating layer, etc., generally, protective structures such as injection molded brackets are used. The injection molded brackets are used to clamp the high-voltage connectors and fix them in the box. Traditional injection molded brackets are generally wire clamp structures. When fixing the protection, the inner wall of the box is used as the protection side, and the high-voltage connector is pressed on the inner wall of the box. Then, the injection molded bracket is fixed on the inner wall of the box. Therefore, the injection molded bracket has certain restrictions on the protective position of the high-voltage connector, resulting in the arrangement of the high-voltage connector being limited to the inner wall of the box for routing, affecting its spatial arrangement in the box.

[0039] Based on this, in order to address the problem that the protective position of the connector in traditional battery devices is restricted, which affects its spatial arrangement, the present application provides a battery device. When the connector is arranged in the box, the connector can be inserted between the first protective member and the second protective member, so that the connector is protected between the first protective member and the second protective member. The connector protected between the first protective member and the second protective member can be fixed in the box by a fixing assembly. This can reduce the risks of collision interference, wear of the insulating layer, etc. between the connector and other structures, and provide effective protection. Since the connector is located between the first protective member and the second protective member, and is fixed in the box by the fixing assembly on the base, the connector does not need to be attached to the side wall of the box for protection and fixation, which effectively reduces the restrictions on the protection position and facilitates the spatial arrangement of the connector in the box.

[0040] The battery cells disclosed in the embodiments of the present application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. A power supply system comprising the battery cells and battery devices disclosed in the present application can be used to form the electrical device.

[0041] The present invention provides an electrical device that uses a battery device as a power source. The electrical device may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, etc. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc. The spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0042] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0043] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery device 100 is provided inside the vehicle 1000. The battery device 100 may be provided at the bottom, head or tail of the vehicle 1000. The battery device 100 may be used to power the vehicle 1000. For example, the battery device 100 may serve as an operating power source for the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300. The controller 200 is used to control the battery device 100 to power the motor 300, for example, for starting, navigating and operating power requirements of the vehicle 1000 during driving.

[0044] In some embodiments of the present application, the battery device 100 can serve not only as an operating power source for the vehicle 1000 , but also as a driving power source for the vehicle 1000 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000 .

[0045] Please refer to Figure 2 , Figure 2 This is an exploded view of a battery device 100 provided in some embodiments of the present application. The battery device 100 includes a housing 20 and a battery cell 10, with the battery cell 10 housed within the housing 20. The housing 20 provides a storage space for the battery cell 10 and can have various structures. In some embodiments, the housing 20 can include a first portion 21 and a second portion 22, which overlap each other and together define a storage space for the battery cell 10. The second portion 22 can be a hollow structure with one end open. The first portion 21 can be a plate-like structure, with the first portion 21 overlapping the open side of the second portion 22, so that the first portion 21 and the second portion 22 together define a storage space. Alternatively, the first portion 21 and the second portion 22 can each be a hollow structure with one end open, with the open side of the first portion 21 overlapping the open side of the second portion 22. Of course, the housing 20 formed by the first portion 21 and the second portion 22 can have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0046] In the battery device 100, there may be multiple battery cells 10, and the multiple battery cells 10 may be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to a combination of series and parallel connections among the multiple battery cells 10. The multiple battery cells 10 may be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery device 10 may be housed within the housing 20. Of course, the battery device 100 may also be a battery module formed by first connecting multiple battery cells 10 in series, in parallel, or in a hybrid connection, and then the multiple battery device 100 modules are further connected in series, in parallel, or in a hybrid connection to form an entire battery device, and then housed within the housing 20. The battery device 100 may also include other structures, for example, the battery device 100 may further include a busbar component for electrically connecting the multiple battery cells 10.

[0047] Each battery cell 10 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 10 can be cylindrical, flat, rectangular, or in other shapes.

[0048] According to some embodiments of this application, please refer to Figures 3 to 5The present application provides a battery device 100, which includes: a housing 20, a connector 60, and a protective structure 40. The connector 60 is at least partially located within the housing 20. The protective structure 40 includes a fixing assembly 4b and a protective assembly 4a connected to the fixing assembly 4b. The fixing assembly 4b is fixed within the housing 20. The protective assembly 4a includes a base 41 and a first protective member 42 and a second protective member 43 spaced apart from each other along a first direction X. The side of the base 41 facing away from the first protective member 42 is connected to the fixing assembly 4b, and a portion of the connector 60 is located between the first protective member 42 and the second protective member 43.

[0049] The connector 60 refers to an element in the battery device 100 for transmitting electrical energy or collecting signals. The connector 60 generally includes a conductor and an insulating protective material wrapped around the outer periphery of the conductor, such as a heat shrink tube and an insulating mesh tube. As an example, the connector 60 can be a high-voltage copper bar, a high-voltage aluminum bar, or a sampling wire harness. In order to reduce the risk of collision interference, wear, etc. of the connector 60 under complex working conditions such as vibration, impact, and temperature changes of the vehicle 1000, the connector 60 can be inserted between the first protective member 42 and the second protective member 43, and the first protective member 42 and the second protective member 43 are used to provide protection for the connector 60.

[0050] The first protective member 42 and the second protective member 43 are spaced apart on the base 41, forming a gap therebetween. This gap can accommodate a portion of the connector 60, positioning the connector 60 between the first protective member 42 and the second protective member 43. This reduces friction between the connector 60 and the housing 20 and the internal structures of the housing 20, thereby reducing the likelihood of damage to the connector 60. Furthermore, the use of the first and second protective members 42, 43 to protect the connector 60 helps reduce the thickness of the insulating protective material of the connector 60, reduces the space occupied by the connector 60 within the housing, and reduces layout difficulty. Furthermore, the protective structure 40 of this embodiment occupies relatively little space, which facilitates the arrangement of the connector 60 within the housing 20. The first direction X of this embodiment can be any direction on the base 41, for example, the first direction X can be the width direction of the base 41 or the length direction of the base 41. It should be explained that in some examples, there is an open end between one end of the first protective member 42 away from the base 41 and one end of the second protective member 43 away from the base 41, that is, the end of the first protective member 42 away from the base 41 and the end of the second protective member 43 away from the base 41 are connected to the outside world and are not closed by other structures. They are in an open state, which makes it more convenient to set connectors 60 of different specifications between the first protective member 42 and the second protective member 43.

[0051] To provide a wider area of ​​protection, both the first and second protective members 42, 43 can be designed as plate-like structures. Furthermore, the first and second protective members 42, 43 can be connected to the base 41 in a variety of ways, including, but not limited to, bolting, clamping, riveting, and welding. Of course, the first and second protective members 42, 43, and base 41 are designed as an integrated structure, for example, using an integrated molding process such as injection molding, bending, and stamping.

[0052] Furthermore, the fixing assembly 4b is the component that secures the protective assembly 4a within the housing 20. Its location within the housing 20 is not restricted, as long as it satisfies the distributed fixation and protective requirements of the connector 60. The fixing assembly 4b can be connected within the housing 20 in a variety of ways, such as bolting, clamping, and riveting. Furthermore, to facilitate securing and protective operations, the fixing assembly 4b can be secured to the side of the base 41 facing away from the first protective member 42.

[0053] In some embodiments, the protective structure 40 may further include an elastic body 44 , which may apply an elastic force along the first direction X to the connecting member 60 , so that the connecting member 60 is stably maintained between the first protective member 42 and the second protective member 43 .

[0054] With this design, the connector 60 is located between the first protective member 42 and the second protective member 43, and is fixed in the box 20 by the fixing component 4b on the base 41. Therefore, the connector 60 does not need to be attached to the side wall of the box 20 for protective fixation, which effectively reduces the restrictions on the protective position and facilitates the spatial arrangement of the connector 60 in the box 20.

[0055] According to some embodiments of the present application, optionally, please refer to Figure 5 The protective component 4a further includes an elastic body 44 , and the elastic body 44 is attached to at least one of the two side surfaces of the first protective member 42 and the second protective member 43 facing each other.

[0056] An elastic member 44 is disposed on the side of the first protective member 42 and / or the second protective member 43 so that the elastic member 44 can abut the connector 60 along the first direction X. This not only maintains the connector 60 between the first protective member 42 and the second protective member 43, but also separates the connector 60 from direct contact with the first protective member 42 or the second protective member 43, thereby reducing friction. When there is only one connector 60, the elastic member 44 can be disposed between the connector 60 and the first protective member 42 and / or the second protective member 43. When there are multiple connectors 60, the elastic member 44 can be disposed between the connector 60 and the first protective member 42 and / or the second protective member 43, or between two adjacent connectors 60. Of course, in some embodiments, the elastic member 44 may not be disposed between two adjacent connectors 60.

[0057] Specifically in some examples, elastic bodies 44 are attached to both sides of the first protective member 42 and the second protective member 43 facing each other.

[0058] It should also be noted that the elastic body 44 can exert an elastic force on the connector 60 along the first direction X, so that the connector 60 is stably maintained between the first protective member 42 and the second protective member 43. The position of the elastic body 44 can be designed in various ways. For example, the elastic body 44 can be set on the side of the first protective member 42 facing the second protective member 43, or on the side of the second protective member 43 facing the first protective member 42. Of course, it can also be set between connectors 60. For example, when two or more connectors 60 are inserted between the first protective member 42 and the second protective member 43 in parallel, the elastic body 44 can be set between two adjacent connectors 60. This eliminates the gap between the connectors 60 along the first direction X, so that each connector 60 is squeezed between the first protective member 42 and the second protective member 43. In this way, the elastic body 44 exerts an elastic force along the first direction X on the connector 60, not only stabilizing the connector 60 between the first protective member 42 and the second protective member 43, but also utilizing the elasticity of the elastic body 44 to accommodate connectors 60 of varying sizes, effectively improving the suitability of the protective design for the connector 60. Furthermore, the elastic body 44 can be made of a variety of materials, such as, but not limited to, rubber and foam. Furthermore, the elastic body 44 can be positioned between the connectors 60 to reduce wear between the connectors 60.

[0059] With this design, the elasticity of the elastomer 44 can be utilized to meet the needs of fixing connectors 60 of different specifications, effectively improving the applicability of protection for the connector 60; at the same time, it also separates the direct contact between the connector 60 and the first protective member 42 or the second protective member 43, reducing friction; in addition, it can also provide effective buffering.

[0060] According to some embodiments of the present application, optionally, please refer to Figure 6 The protective component 4a further includes a spacer 48 , and the number of the connecting members 60 is at least two, with a spacer 48 sandwiched between two adjacent connecting members 60 .

[0061] As can be seen, when at least two connectors 60 penetrate between the first protective member 42 and the second protective member 43, at least some of the connectors 60 are arranged in parallel along the first direction X. In this case, spacers 48 can be provided between the connectors 60 to eliminate gaps along the first direction X, ensuring that each connector 60 is stably squeezed between the first protective member 42 and the second protective member 43. Furthermore, the spacers 48 separate adjacent connectors 60, reducing friction between them. The number and thickness of the spacers 48 can be determined based on design requirements.

[0062] For some specific examples, please refer to Figure 6 Elastic bodies 44 are provided between the first protective member 42 and the connecting member 60, and between the second protective member 43 and the connecting member 60. Spacers 48 are provided between the connecting members 60. This not only stably constrains each connecting member 60 between the first protective member 42 and the second protective member 43, but also helps reduce wear on the connecting members 60. The spacers 48 may have the same structure as the elastic body 44, or a different structure.

[0063] Such a design enables each connecting member 60 to be stably confined between the first protective member 42 and the second protective member 43 ; at the same time, the mutual friction between the connecting members 60 is reduced, thereby providing effective protection for each connecting member 60 .

[0064] According to some embodiments of the present application, optionally, the elastic body 44 is foam.

[0065] Foam is a material made of foamed plastic particles, which can be but is not limited to PU (Polyurethane) foam, anti-static foam, pearl cotton, etc.

[0066] Such a design and the introduction of foam not only stably define the connecting member 60 between the first protective member 42 and the second protective member 43 , but also is lightweight, thereby reducing the overall weight of the protective structure 40 .

[0067] According to some embodiments of the present application, optionally, please refer to Figure 6 The battery device 100 further includes a support beam 30 , which is disposed in the box body 20 , and the fixing assembly 4 b is fixed to the support beam 30 .

[0068] The support beam 30 is a beam structure fixed in the box 20, which can provide resistance to the expansion of the battery cell 10, making the structure of the battery device 100 more stable. Figure 4 The box body 20 includes a first part 21 and a second part 22 that cooperate with each other, and the support beam 30 is arranged in the second part 22.

[0069] The fixing assembly 4b can be fixed to the support beam 30 in various locations, for example, the fixing assembly 4b can be fixed to the top 32 of the support beam 30 or to the side of the support beam 30. The top 32 of the support beam 30 refers to one end of the support beam 30 along its height direction Z; the side of the support beam 30 refers to the surface of the support beam 30 along its thickness direction Y, and can also be understood as the surface of the support beam 30 facing toward or away from the battery cell 10.

[0070] In addition, there are many ways to fix the fixing component 4b on the support beam 30, such as but not limited to bolt connection, clamping, riveting, welding, etc.

[0071] With this design, the fixing assembly 4 b is fixed on the support beam 30 , making it easier for the connecting member 60 to be distributed on the support beam 30 .

[0072] According to some embodiments of the present application, optionally, please refer to Figure 5 The fixing assembly 4b includes two limit members 45 and a locking member 46. The two limit members 45 are spaced apart on the side of the base 41 facing away from the first protective member 42 and are respectively located on both sides of the support beam 30 along its own thickness direction Y. The locking member 46 is provided on at least one limit member 45 and fixed to the support beam 30. The first direction X intersects with the thickness direction Y of the support beam 30.

[0073] It can be seen that during the fixing process, the two limiting members 45 can be respectively clamped on both sides of the support beam 30 along its own thickness direction Y; then, at least one limiting member 45 is fixed to the side of the support beam 30 using the locking member 46, so that the fixing assembly 4b is stably fixed to the support beam 30. Because the first direction X intersects with the thickness direction Y of the support beam 30, when the fixing assembly 4b is clamped on the support beam 30, the connecting member 60 inserted between the first protective member 42 and the second protective member 43 can pass through the top 32 of the support member along the thickness direction Y of the support beam 30, making the distribution of the connecting member 60 more reasonable. Specifically, in some examples, the first direction X is perpendicular to the thickness direction Y of the support beam 30. The thickness direction Y of the support beam 30 can be understood as the direction from the side of the support beam 30 toward the battery cell 10 to the side of the support beam 30 facing away from the battery cell 10.

[0074] The stopper 45 is disposed on the side of the base 41 facing away from the first protective member 42. It can be disposed on the surface of the base 41 facing away from the first protective member 42, or on the edge of the base 41. The stopper 45 can be connected to the base 41 in a variety of ways, such as, but not limited to, bolting, clamping, and welding. Of course, the stopper 45 and the base 41 are an integrated structure, for example, produced through an integral molding process such as injection molding, extrusion, or bending.

[0075] In addition, the locking member 46 can be provided on one of the limiting members 45 or on both limiting members 45. When two limiting members 45 are provided on both limiting members 45, the limiting members 45 on both sides can be fixed to the support beam 30 by the locking member 46. The locking member 46 can be, but is not limited to, a bolt, a rivet, etc.

[0076] In this design, the two limit members 45 are respectively set on both sides of the support beam 30, so that the fixing component 4b can be stably stuck on the support beam 30, thereby improving the stability of the structure; at the same time, the first direction X is intersected with the thickness direction Y of the support beam 30, so that the connecting member 60 can pass through the top 32 of the support member more easily, making the distribution of the connecting member 60 more reasonable.

[0077] According to some embodiments of the present application, optionally, please refer to Figure 7 and Figure 8 The fixing assembly 4 b further includes a positioning protrusion 47 . The locking member 46 and the positioning protrusion 47 are respectively provided on the two limiting members 45 . The positioning protrusion 47 cooperates with the positioning hole 33 on the support beam 30 .

[0078] During the fixing process, the two limit members 45 can be respectively clamped on both sides of the support beam 30; then, the positioning protrusion 47 is engaged with the positioning hole 33 on the support beam 30, so that the fixing component 4b is initially positioned, so that the locking member 46 can be stably fixed on the side of the support beam 30.

[0079] Of course, in some other embodiments, please refer to Figure 5 The two locking members 46 are respectively arranged on the two limiting members 45 , so that when fixing, the two limiting members 45 are respectively clamped on both sides of the support beam 30 , and then the locking members 46 fix each limiting member 45 on the side of the support beam 30 .

[0080] With this design, the positioning protrusion 47 is introduced to cooperate with the positioning hole 33, so as to facilitate the stable positioning of the fixing component 4b on the support beam 30.

[0081] According to some embodiments of the present application, optionally, please refer to Figure 8 Each limiting member 45 can be rotated or bent relative to the base 41 in a direction in which the two limiting members 45 are moved toward or away from each other.

[0082] It can be seen that the angle between the limiter 45 and the base 41 is adjustable, so that the limiter 45 can better abut against the side of the support beam 30, so that the two limiters 45 are stably clamped on the two side surfaces of the support beam 30, thereby improving the stability of the installation of the fixing component 4b on the support beam 30.

[0083] The limiter 45 can be adjusted by bending, for example, by providing a certain degree of ductility at the connection between the limiter 45 and the base 41, allowing the limiter 45 to bend on the base 41. The limiter 45 can also be adjusted by rotation, for example, by hingedly securing the limiter 45 to the base 41. Rotating the limiter 45 can change the angle between the limiter 45 and the base 41, thereby allowing the limiter 45 to better fit the side of the support beam 30. It is readily understood that bending adjustment refers to the ability to bend the limiter 45 starting from the connection between the limiter 45 and the base 41.

[0084] In this design, the limit member 45 is designed as an adjustable structure, so that the limit member 45 can be more adapted to the side of the support beam 30, so that the limit member 45 can be better fixed on the support beam 30, thereby improving the stability of the installation.

[0085] According to some embodiments of the present application, optionally, please refer to Figure 6 A groove 31 is provided at the top 32 of the support beam 30 along its own height direction Z, and at least a portion of the protective component 4 a is located in the groove 31 .

[0086] The groove 31 refers to the notch structure at the top 32 of the support beam 30, which penetrates the support beam 30 along the thickness direction Y of the support beam 30. In this way, when the connecting member 60 is distributed, the protective structure 40 can be placed in the groove 31, so that the two limiting members 45 are respectively stuck on the two side surfaces of the support beam 30.

[0087] Specifically, in some examples, the groove 31 includes a bottom wall 311 and a first inner wall 312 and a second inner wall 313 spaced apart along a first direction X. The base 41 is disposed on the bottom wall 311, and the first and second protective members 42 and 43 correspond to the first and second inner walls 312 and 313, respectively. It can be seen that the first and second protective members 42 and 43 correspond to the first and second inner walls 312 and 313, respectively, of the groove 31. This allows the connector 60 to pass through the groove 31 after passing between the first and second protective members 42 and 43, effectively routing the connector 60 on the support beam 30. Furthermore, the first and second protective members 42 and 43 reduce friction between the connector 60 and the edges of the first and second inner walls 312 and 313, respectively.

[0088] When the first protective member 42 and the second protective member 43 correspond to the first inner wall 312 and the second inner wall 313 of the groove 31, respectively, the first protective member 42 can be attached to the first inner wall 312, and the second protective member 43 can be attached to the second inner wall 313. Of course, in other embodiments, the first protective member 42 can also be separated from the first inner wall 312, and the second protective member 43 can be separated from the second inner wall 313.

[0089] Furthermore, this embodiment places the protective structure 40 within the groove 31, effectively protecting the distributed connectors 60. Compared to structures such as those using a covered wear-resistant mesh tube, this can reduce the size of the protected connectors 60, thereby reducing the space occupied by the groove 31 on the support beam 30, thereby indirectly improving the structural strength of the support beam 30 and, in turn, enhancing the anti-expansion capability of the box 20.

[0090] With this design, a groove 31 is introduced on the support beam 30, which facilitates the effective routing of the connector 60 on the support beam 30; at the same time, the first protective member 42 and the second protective member 43 are used to reduce the contact between the connector 60 and the inner wall of the groove 31, thereby achieving effective protection.

[0091] According to some embodiments of the present application, optionally, please refer to Figure 9 The battery device 100 includes a restraining assembly 50 , which is disposed on the first protective member 42 and / or the second protective member 43 , and a portion of the connecting members 60 are fixed to the restraining assembly 50 .

[0092] When the number of connectors 60 between the first and second guard members 42, 43 increases, the space between them along the first direction X increases. This increases the space occupied within the housing 20. For example, the space in the recess 31 of the support beam 30 must be increased to accommodate the guard assembly 4a. However, this can also easily reduce the structural strength of the support beam 30. To this end, when there are at least two connectors 60, a restraining assembly 50 is introduced. Some of the connectors 60 are positioned between the first and second guard members 42, 43, and some of the connectors 60 are secured to the restraining assembly 50. This reduces the number of connectors 60 required to be secured between the first and second guard members 42, 43. In this case, some of the connectors 60 can be distributed sequentially along the height of the guard structure 40.

[0093] The restraint assembly 50 is a structure that can restrain the connector 60, and the restraint method can be binding, clamping, etc. At the same time, the connection method of the restraint assembly 50 on the first protective member 42 or the second protective member 43 can be, but is not limited to, socket connection, clamping, bolt connection, etc.

[0094] With such a design, a constraint component 50 is introduced, and a certain number of connectors 60 can pass between the first protective member 42 and the second protective member 43. The constraint component 50 can be used to provide fixed points for routing other connectors 60, thereby improving the flexibility of routing different connectors 60, so as to optimize the layout of the connectors 60 in the box.

[0095] According to some embodiments of the present application, optionally, please refer to Figure 9 and Figure 10The base 41 includes a supporting portion 411 and an extending protrusion 412, the extending protrusion 412 is protruded along the first direction X at one end of the supporting portion 411, the first protective member 42 is provided on the extending protrusion 412, the second protective member 43 is provided at one end of the supporting portion 411 away from the extending protrusion 412, and the restraint assembly 50 is provided on the first protective member 42.

[0096] The extended protrusion 412 is a structure that extends from one end of the supporting portion 411 in the first direction X. This extends the size of the base 41 in the first direction X. This allows the restraint assembly 50 to be installed on the first protective member 42, thereby restraining a portion of the connector 60 while maintaining the protective space between the first protective member 42 and the second protective member 43. The extended protrusion 412 and the supporting portion 411 can be joined by welding, bolting, or snap-fitting, or can be designed as an integrated structure.

[0097] With this design, the extension protrusion 412 is introduced, so that the restraining assembly 50 can restrain part of the connecting member 60 without affecting the protective space between the first protective member 42 and the second protective member 43 .

[0098] According to some embodiments of the present application, optionally, please refer to Figure 9 The restraint assembly 50 includes a mounting member 52 and a restraint member 51 connected to the mounting member 52 . The mounting member 52 is detachably connected to the first protective member 42 and / or the second protective member 43 . The restraint member 51 is used to bind part of the connecting member 60 .

[0099] The mounting member 52 refers to a component for mounting the restraint assembly 50 on the first protective member 42 and / or the second protective member 43, and can be designed as a circular, square, or other structure. The restraint member 51 refers to a component for fixing the connector 60 by binding, and can be, but not limited to, a cable tie, etc., so that the connector 60 is fixed to the first protective member 42 and / or the second protective member 43 by binding. The connection method of the mounting member 52 on the first protective member 42 and / or the second protective member 43 can be, but not limited to, a snap connection, a sleeve connection, a bolt connection, etc. The sleeve connection method can be understood as: an opening is provided at the bottom of the mounting member 52, and one end of the first protective member 42 and / or the second protective member 43 is inserted into the opening, so that the mounting member 52 covers one end of the first protective member 42 and / or the second protective member 43. At the same time, the number of restraint members 51 can be one or more.

[0100] With this design, a portion of the connecting member 60 is stably constrained on the protective structure 40 through the mounting member 52 and the constraining member 51 .

[0101] According to some embodiments of the present application, optionally, please refer to Figure 11The mounting member 52 includes a mounting protrusion 522 and a socket portion 521 socketed on the first protective member 42 and / or the second protective member 43. The mounting protrusion 522 is provided at at least one end of the socket portion 521 along the second direction and extends and protrudes along the second direction. A mounting groove 523 is provided on the surface of the mounting protrusion 522 facing the connecting member 60, and the restraint member 51 is at least partially provided in the mounting groove 523. The second direction is the length direction of the connecting member 60 located between the first protective member 42 and the second protective member 43.

[0102] The sleeve portion 521 refers to the component on the mounting member 52 that covers the first protective member 42 and / or the second protective member 43. The mounting protrusion 522 is a structure protruding from one end of the sleeve portion 521. Extending the mounting protrusion 522 along the length of the connector 60 and positioning the restraining member 51 on the mounting protrusion 522 reduces the space occupied by the restraining member 51 between the first and second protective members 42 and 43. Furthermore, a mounting groove 523 is provided on the surface of the mounting protrusion 522 facing the connector 60 to reduce the height of the restraining member 51 on the mounting protrusion 522 along the first direction X, thereby reducing interference with the distribution of the connector 60.

[0103] Optionally, the mounting protrusion 522 and the sleeve portion 521 may be connected by bolt connection, welding, riveting, bonding, etc., or the two may be designed as an integrated structure.

[0104] Specifically, in some examples, the restraining member 51 may include a mounting base and a cable tie mounted on the mounting base. The mounting base is disposed within the mounting slot 523, and the cable tie is used to bind the connecting member 60. The cable tie and the mounting base may also be designed to be detachably connected to facilitate replacement of the cable tie. The detachable connection may be, but is not limited to, a bolt connection, a clamp connection, or the like.

[0105] Such a design, with the introduction of the mounting protrusion 522 and the mounting groove 523 , can reduce the space occupied by the restraining member 51 between the first protective member 42 and the second protective member 43 , as well as the installation height along the first direction X, thereby facilitating better arrangement of the connecting member 60 .

[0106] According to some embodiments of the present application, optionally, please refer to Figure 11 The bottom surface of the mounting protrusion 522 facing the base 41 includes a avoidance surface 52a, the avoidance surface 52a is inclined relative to the second direction, and the distance between the avoidance surface 52a and the base 41 gradually increases from the end of the avoidance surface 52a close to the socket portion 521 to the end of the avoidance surface 52a away from the socket portion 521.

[0107] The distance between the avoidance surface 52a and the base 41 can be understood as the vertical distance between the avoidance surface 52a and the base 41. For ease of understanding, the distance between the avoidance surface 52a and the base 41 can be Figure 11The distance D represents in the figure. The distance between the avoidance surface 52a and the base 41 increases as it moves away from the sleeve portion 521 in the second direction. This means that the bottom space of the mounting protrusion 522 increases as it moves away from the sleeve portion 521, which helps to reduce the space occupied by the protective structure 40 in the second direction.

[0108] With this design, the space at the bottom of the mounting protrusion 522 becomes larger as it moves away from the sleeve portion 521 , which helps to reduce the space occupied by the protective structure 40 in the second direction.
