Description

Technical Field

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

[0002] During use, the battery device needs to be installed in different electrical devices. Therefore, a mounting structure is usually provided on the housing of the battery device, and the mounting structure can realize the connection and fixation between the battery device and the electrical device.

[0003] However, the current mounting structure is relatively fixed in position on the box, lacking in installation flexibility, and is prone to displacement of the mounting point when the mounting structure is connected to the box, affecting the installation accuracy of the mounting structure on the box. Utility Model Content

[0004] Based on this, it is necessary to provide a battery device and electrical equipment to address the problems that the current mounting structure is relatively fixed in position on the box, the installation flexibility is insufficient, and the installation point position is easily offset when the mounting structure is connected to the box, affecting the installation accuracy of the mounting structure on the box.

[0005] In the first aspect, the present application provides a battery device, including a box, a battery cell, a mounting bracket and a mounting sleeve; the battery cell is arranged inside the box; the mounting bracket is fixedly connected to the box, and an installation groove is opened on the mounting bracket, and the mounting sleeve is glued and fixed in the mounting groove.

[0006] With the above structure, the mounting sleeve is first positioned on the housing by connecting the mounting bracket to the housing. This allows the mounting bracket to be attached to a specific location on the housing according to actual usage requirements, allowing for more flexible adjustment of the mounting position on the housing to meet the mounting and installation requirements of different battery devices. Furthermore, after the mounting bracket is secured to the housing, the mounting sleeve is secured to the mounting slot by gluing, i.e., a cold connection is used to connect the mounting sleeve to the mounting bracket. This reduces heat input, lowers the probability of mounting point position deviation, and improves installation accuracy at the mounting location.

[0007] In some embodiments, a glue groove is further provided on the mounting bracket, and the glue groove is arranged on the outer periphery of the installation groove and is connected to the installation groove.

[0008] By providing the glue groove, it can be used to accommodate more structural glue, and the mounting sleeve can be glued and fixed in the mounting groove by the structural glue, thereby improving the stability of the mounting sleeve in the mounting groove.

[0009] In some embodiments, the mounting bracket includes a first frame and a second frame mounted on the first frame along a preset direction, a first through hole is opened on the first frame, and a second through hole is opened on the second frame, the first through hole and the second through hole correspond to each other and are spaced apart along the preset direction, and are connected to form a mounting groove; wherein, the inner diameter of the second through hole is not less than the outer diameter of the mounting sleeve, and the inner diameter of the first through hole is less than the outer diameter of the mounting sleeve.

[0010] By providing the first and second frames, and respectively providing the first and second through holes, a mounting groove can be smoothly formed to facilitate securing the mounting sleeve within the mounting groove. In addition, the structure of the first and second frames cooperating with each other can also effectively reduce the overall weight of the mounting bracket, achieving lightweight design.

[0011] In some embodiments, the glue groove includes a first sub-groove opened on the first frame, the first sub-groove is arranged around the outer periphery of the first through hole and is connected to the first through hole; wherein the bottom wall of the first sub-groove is used to support the mounting sleeve.

[0012] Through the above structure, the mounting sleeve can be positioned in the installation groove and at the same time, the mounting sleeve can be adhesively fixed by the structural adhesive in the first sub-groove, thereby improving the stability of the mounting sleeve in the installation groove.

[0013] In some embodiments, the glue groove includes a second sub-groove formed on the second frame. The second sub-groove is disposed around the outer periphery of the second through hole and communicates with the second through hole.

[0014] Through the above structure, the mounting sleeve can be positioned in the installation groove and at the same time, the mounting sleeve can be adhesively fixed by the structural adhesive in the second sub-groove, thereby improving the stability of the mounting sleeve in the installation groove.

[0015] In some embodiments, the first frame includes a first body and a first connecting wall connected to each other, the first through hole is opened on the first body, and the first connecting wall is used to fit and be fixedly connected to the surface of the box.

[0016] By providing the first connecting wall, the contact area between the first frame and the box body can be increased, making the connection between the first frame and the box body more stable.

[0017] In some embodiments, the second frame includes a second body and a second connecting wall connected to each other, the second through hole is opened on the second body, the second connecting wall is coplanar with the first connecting wall, and is used to fit and be fixedly connected to the surface of the box.

[0018] Through the above structure, not only the contact area between the second frame and the box body can be increased, making the connection between the second frame and the box body more stable, but also the overall contact area between the mounting bracket and the box body can be further increased, making the connection between the mounting bracket and the box body more stable.

[0019] In some embodiments, in a direction intersecting with a preset direction and parallel to the first connecting wall or the second connecting wall, the width of the first body and / or the second body gradually increases along the direction in which the mounting sleeve is inserted into the mounting slot.

[0020] With the above structure, the structure of the first body and the second body can better meet the requirements of increasing the stress at the bottom of the mounting bracket and increasing the load-bearing area during the mounting process. This can optimize the load-bearing area of the mounting bracket and reduce the probability of cracking in the weld between the mounting bracket and the box.

[0021] In some embodiments, a groove is formed on a surface of the first connecting wall facing the box body, and the groove is connected to the glue groove.

[0022] In this way, when the structural adhesive is filled into the first sub-groove, the structural adhesive will flow into the groove, so that an adhesive connection between the first connecting wall and the box body can be achieved, further strengthening the connection strength between the mounting bracket and the box body.

[0023] In some embodiments, a plug welding hole is formed through the first connecting wall. Through the above structure, the first connecting wall and the box body can be smoothly welded together, thereby improving the connection stability between the two.

[0024] In a second aspect, the present application also provides an electrical device comprising the battery device as described above.

[0025] The above-mentioned battery device and electrical equipment, first, are connected to the box body through a mounting bracket to realize the positioning of the mounting sleeve on the box body. Therefore, the mounting bracket can be connected to the specified position on the box body according to actual use requirements, so as to more flexibly adjust the mounting position on the box body to meet the mounting and installation requirements of different battery devices; in addition, after the mounting bracket is fixed to the box body, the mounting sleeve is fixed to the mounting groove by gluing, that is, the connection between the mounting sleeve and the mounting bracket is realized by a cold connection method, which can reduce heat input, reduce the probability of offset of the mounting point position, and improve the installation accuracy of the mounting position.

[0037] 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.

[0041] 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 such as electric bicycles, electric motorcycles, and electric vehicles, as well as in other fields. As the application of power batteries continues to expand, market demand is also growing.

[0042] A battery device is composed of one or more battery cells. For each battery device, the battery cells can be connected in series, in parallel, or in a mixed connection. Mixed connection means that the battery cells are connected in both series and parallel.

[0043] A battery assembly typically consists of a housing, battery cells housed within it, and other functional components. During use, the battery assembly must be installed in a corresponding electrical device. Therefore, a mounting structure is typically installed on the outside of the housing to secure the battery assembly to its proper location.

[0044] Current mounting structures can be categorized as either integrated or split. Integrated mounting structures are integrally formed with the enclosure, typically with multiple mounting points centrally located. This means the mounting points are relatively fixed in position, making them inadequate for some specialized mounting configurations. Split mounting structures, on the other hand, require welding to the enclosure. Heat input during welding can easily cause deformation, leading to offset mounting points and impacting the mounting accuracy of the enclosure.

[0045] Based on the above considerations, one or more embodiments of the present application provide a battery device. First, the mounting bracket is connected to the housing to achieve the positioning of the mounting sleeve on the housing. As a result, the mounting bracket can be connected to a specified position on the housing according to actual use requirements, thereby more flexibly adjusting the mounting position on the housing to meet the mounting and installation requirements of different battery devices. In addition, after the mounting bracket is fixed to the housing, the mounting sleeve is fixed to the mounting groove by gluing, that is, the connection between the mounting sleeve and the mounting bracket is achieved by cold connection, which can reduce heat input, reduce the probability of the mounting point position offset, and improve the installation accuracy of the mounting position.

[0046] It should be noted that the battery device mentioned in the embodiments of the present application may include one or more battery cell assemblies for providing voltage and capacity. The battery cell assembly may include multiple battery cells, which are connected in series, parallel, or hybrid via a busbar.

[0047] In some embodiments, a battery cell assembly is typically formed by arranging multiple battery cells. For example, the battery cell assembly may be a battery module, which is formed by arranging and securing multiple battery cells into a single module. For example, a battery module may be formed by bundling multiple battery cells using cable ties.

[0048] In some embodiments, the battery device may be a battery pack, which includes a case and one or more battery cell assemblies, wherein the battery cell assemblies are housed in the case.

[0049] As an example, the battery cell assembly may be a battery module, and the battery cell assembly may be accommodated in the box by fixing the battery module in the box.

[0050] As an example, the battery cell assembly may also be housed in the box by directly fixing the plurality of battery cells to the box.

[0051] The battery device disclosed in the embodiments of the present application can be used in, but is not limited to, electrical equipment such as vehicles, ships, or aircraft.

[0052] The present invention provides an electrical device that uses a battery device as a power source. The electrical device may include, 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, and the like. 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, and the spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, and the like.

[0053] For the convenience of description, the following embodiments are described by taking a vehicle as an example of an electrical device in an embodiment of the present application.

[0054] Please refer to Figure 1 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, to meet the power requirements for starting, navigating and driving the vehicle 1000.

[0055] 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 .

[0056] Please refer to Figure 2The battery device 100 includes a housing 10 and a battery cell 20, with the battery cell 20 housed within the housing 10. The housing 10 is used to provide a storage space for the battery cell 20, and the housing 10 can have a variety of structures. In some embodiments, the housing 10 can include a first portion 11 and a second portion 12, which cover each other and together define a storage space for the battery cell 20. The second portion 12 can be a hollow structure with one end open, and the first portion 11 can be a plate-like structure, with the first portion 11 covering the open side of the second portion 12, so that the first portion 11 and the second portion 12 together define a storage space. The first portion 11 and the second portion 12 can also be hollow structures with one end open, with the open side of the first portion 11 covering the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 can have a variety of shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0057] In the battery device 100, there may be multiple battery cells 20, which 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 20. The multiple battery cells 20 may be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery unit 20 may be housed within the housing 10. Alternatively, the battery device 100 may comprise multiple battery cells 20 connected in series, in parallel, or in a hybrid connection to form a battery module, which is then further connected in series, in parallel, or in a hybrid connection to form a single unit and housed within the housing 10. The battery device 100 may also include other structures, such as a busbar assembly for electrically connecting the multiple battery cells 20.

[0058] Each battery cell 20 may be a secondary battery or a primary battery, and may also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or in other shapes.

[0059] Please refer to Figure 3A battery cell 20 is the smallest unit that makes up a battery. A battery cell 20 typically includes a top cover 21, a housing 22, an electrode assembly 23, and other functional components. The top cover 21 is a component that covers the opening of the housing 22 to isolate the internal environment of the battery cell 20 from the external environment. Without limitation, the shape of the top cover 21 can be adapted to the shape of the housing 22 to match the housing 22. Functional components such as electrode terminals, also known as electrode posts, can be provided on the top cover 21. The electrode terminals can be used to electrically connect to the electrode assembly 23 to output or input electrical energy from the battery cell 20. In some embodiments, the top cover 21 can also be provided with a pressure relief mechanism for relieving internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold. In some embodiments, an insulating member can also be provided on the inner side of the top cover 21 to isolate the electrical connection components in the housing 22 from the top cover 21 to reduce the risk of short circuits. Exemplary insulating members can be made of plastic, rubber, etc.

[0060] The shell 22 is a component used to cooperate with the top cover 21 to form the internal environment of the battery cell 20, wherein the formed internal environment can be used to accommodate the electrode assembly 23, electrolyte and other components. The shell 22 and the top cover 21 can be independent components, and an opening can be set on the shell 22, and the internal environment of the battery cell 20 is formed by covering the opening with the top cover 21. Without limitation, the top cover 21 and the shell 22 can also be integrated. Specifically, the top cover 21 and the shell 22 can form a common connection surface before other components are put into the shell. When the interior of the shell 22 needs to be encapsulated, the top cover 21 is covered with the shell 22. The shell 22 can be of various shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, a hexagonal prism, etc. Specifically, the shape of the shell 22 can be determined according to the specific shape and size of the electrode assembly 23.

[0061] The electrode assembly 23 is a component in the battery cell 20 where electrochemical reactions occur. One or more electrode assemblies 23 may be contained in the housing 22. The electrode assembly 23 is mainly composed of a positive electrode sheet, a separator, and a negative electrode sheet. Specifically, the positive electrode active material and the negative electrode active material are coated on the current collector respectively, thereby forming a positive electrode sheet and a negative electrode sheet respectively. The positive electrode sheet and the negative electrode sheet are wound or stacked, and the separator is arranged between the positive electrode sheet and the negative electrode sheet, thereby forming the electrode assembly 23. The parts of the positive electrode sheet and the negative electrode sheet with active materials constitute the main body of the electrode assembly 23, and the parts of the positive electrode sheet and the negative electrode sheet without active materials each constitute the tab. The positive electrode tab and the negative electrode tab may be located together at one end of the main body or respectively at both ends of the main body. During the charge and discharge process of the battery, the positive electrode active material and the negative electrode active material react with the electrolyte, and the tabs connect the electrode terminals to form a current circuit.

[0062] Please also refer to Figure 2 、 Figure 4 as well as Figure 5 One embodiment of the present application provides a battery device 100, comprising a housing 10, a battery cell 20, a mounting bracket 30, and a mounting sleeve 40. The battery cell 20 is disposed within the housing 10, the mounting bracket 30 is fixedly connected to the housing 10, and a mounting slot 31 is defined on the mounting bracket 30, into which the mounting sleeve 40 is adhesively secured.

[0063] It should be noted that the box body 10 may generally include a box body and a cover body that cover each other, and the box body and the cover body together enclose a receiving cavity to facilitate the placement of the battery cell 20 in the receiving cavity.

[0064] The battery cell 20 is the smallest unit constituting the battery device 100 . The number of the battery cells 20 can be set to one or more, and all the battery cells 20 are placed in the accommodating cavity of the box body 10 so that the box body 10 can protect the battery cells 20 in the accommodating cavity.

[0065] The mounting bracket 30 and mounting sleeve 40 cooperate to mount and secure the housing 10 to a corresponding position on an electrical device. The mounting bracket 30 can be fixedly connected to the housing 10, and then the mounting sleeve 40 can be secured to the mounting bracket 30. During assembly, the mounting sleeve 40 can be connected and secured to a specific structure of the electrical device or other device, thereby enabling the installation and securing of the battery assembly 100.

[0066] Specifically, the mounting bracket 30 and the box body 10 can be fixedly connected by welding, but not limited thereto. The box body 10 can be, but not limited to, a roll-formed box body 10, a profiled box body 10, or a stamped box body 10.

[0067] Furthermore, it is understood that the mounting bracket 30 and the mounting sleeve 40 can be mounted on the outer wall of the box 10, or can be mounted on the top, bottom, or other locations of the box 10 as needed. Furthermore, the mounting bracket 30 and the mounting sleeve 40 can also be applied to other structures in the box 10, such as water-cooling brackets, bottom guard plate brackets, and other structures, which can also be independently mounted, and will not be described in detail here.

[0068] Furthermore, the mounting bracket 30 defines a mounting groove 31 for accommodating the mounting sleeve 40. Specifically, the mounting sleeve 40 is inserted axially into the mounting groove 31, and then structural adhesive is filled between the mounting sleeve 40 and the groove wall of the mounting groove 31 to achieve adhesive fixation of the mounting sleeve 40 within the mounting groove 31.

[0069] Cold-connecting the mounting sleeve 40 and the mounting bracket 30 by gluing can effectively reduce heat input, reduce the probability of deformation during heat input that causes the mounting point position to shift, and improve the installation accuracy of the mounting position.

[0070] With the above structure, first, the mounting bracket 30 is connected to the housing 10 to achieve the positioning of the mounting sleeve 40 on the housing 10. As a result, the mounting bracket 30 can be connected to a specified position on the housing 10 according to actual usage requirements, thereby more flexibly adjusting the mounting position on the housing 10 to meet the mounting and installation requirements of different battery devices 100. In addition, after the mounting bracket 30 is fixed to the housing 10, the mounting sleeve 40 is fixed to the mounting groove 31 by gluing. That is, the connection between the mounting sleeve 40 and the mounting bracket 30 is achieved by cold connection, which can reduce heat input, reduce the probability of deviation of the mounting point position, and improve the installation accuracy of the mounting position.

[0071] In some embodiments, a glue groove 32 is further defined on the mounting bracket 30 . The glue groove 32 is disposed on the outer periphery of the mounting groove 31 and communicates with the mounting groove 31 .

[0072] Specifically, the glue groove 32 is a structure formed on the surface of the mounting bracket 30 and used to accommodate structural glue so that the mounting sleeve 40 is glued and fixed to the mounting groove 31 .

[0073] As a specific embodiment, the adhesive groove 32 can be provided as a whole, surrounding the outer periphery of the mounting groove 31 and communicating with the mounting groove 31. In this way, when the structural adhesive is filled into the mounting groove 31, the structural adhesive spreads along the adhesive groove 32 around the outer periphery of the mounting sleeve 40, thereby more stably fixing the mounting sleeve 40 in the mounting groove 31.

[0074] Furthermore, multiple adhesive grooves 32 can be provided, all of which are spaced apart along the circumference of the mounting groove 31 and are connected to the mounting groove 31. In this way, each adhesive groove 32 is filled with structural adhesive, thereby achieving multi-point connection between the mounting sleeve 40 and the groove wall of the mounting groove 31.

[0075] By providing the glue groove 32 , it can be used to accommodate more structural glue, and the mounting sleeve 40 can be glued and fixed in the installation groove 31 through the structural glue, thereby improving the stability of the mounting sleeve 40 in the installation groove 31 .

[0076] like Figure 4 and Figure 6As shown, in some embodiments, the mounting bracket 30 includes a first frame 33 and a second frame 34 that is sleeved on the first frame 33 along a predetermined direction a. The first frame 33 defines a first through hole 35, and the second frame 34 defines a second through hole 36. The first through hole 35 and the second through hole 36 are spaced apart and arranged in correspondence with each other along the predetermined direction a, and are connected to form the mounting slot 31. The inner diameter of the second through hole 36 is not less than the outer diameter of the mounting sleeve 40, and the inner diameter of the first through hole 35 is less than the outer diameter of the mounting sleeve 40.

[0077] Specifically, the first frame 33 and the second frame 34 can be integrally formed, welded, or connected in other ways. The second frame 34 is sleeved on the first frame 33 along a predetermined direction a, and a first through hole 35 is defined in the first frame 33, and a second through hole 36 is defined in the second frame 34.

[0078] The first through hole 35 and the second through hole 36 are aligned along a predetermined direction a and spaced apart from each other, so that the first through hole 35 and the second through hole 36 can together form a mounting groove 31 , so that the mounting sleeve 40 can be disposed in the mounting groove 31 .

[0079] Furthermore, along the direction in which the mounting sleeve 40 is inserted into the mounting groove 31 , the second through hole 36 is located upstream of the first through hole 35 . That is, during the insertion of the mounting sleeve 40 into the mounting groove 31 , the mounting sleeve 40 first passes through the second through hole 36 and then reaches the first through hole 35 .

[0080] The inner diameter of the second through hole 36 is not less than the outer diameter of the mounting sleeve 40, so that the mounting sleeve 40 can smoothly pass through the second through hole 36 along the preset direction a. In addition, when the mounting sleeve 40 is inserted into the second through hole 36, the second through hole 36 can also form a limit for the mounting sleeve 40.

[0081] The inner diameter of the first through hole 35 is smaller than the outer diameter of the mounting sleeve 40. In this way, after the mounting sleeve 40 passes through the second through hole 36, it can finally abut against the outer wall of the first through hole 35 along the preset direction a. In other words, the bottom end of the mounting sleeve 40 abuts against the first frame 33 on the outer periphery of the first through hole 35 along the preset direction a.

[0082] By providing the first frame 33 and the second frame 34, and respectively providing the first through hole 35 and the second through hole 36, the mounting groove 31 can be smoothly formed to facilitate securing the mounting sleeve 40 within the mounting groove 31. In addition, the structure of the first frame 33 and the second frame 34 cooperating with each other can also effectively reduce the overall weight of the mounting bracket 30, achieving lightweight design.

[0083] In some embodiments, the adhesive groove 32 includes a first sub-groove 321 formed on the first frame 33. The first sub-groove 321 surrounds the first through hole 35 and communicates with the first through hole 35. The bottom wall of the first sub-groove 321 is used to support the mounting sleeve 40.

[0084] Specifically, the first sub-groove 321 is formed on the surface of the first frame 33 and surrounds the outer periphery of the first through-hole 35, communicating with the first through-hole 35. When the mounting sleeve 40 is inserted into the mounting groove 31, the bottom end of the mounting sleeve 40 passes through the second through-hole 36 and abuts against the bottom wall of the first sub-groove 321. This allows the mounting sleeve 40 to be smoothly accommodated within the mounting groove 31.

[0085] The first sub-groove 321 is filled with structural adhesive, so that the mounting sleeve 40 and the groove wall of the first sub-groove 321 can be glued to each other, thereby achieving gluing and fixing of the mounting sleeve 40 .

[0086] Through the above structure, the mounting sleeve 40 can be positioned in the installation groove 31 and the mounting sleeve 40 can be adhesively fixed by the structural adhesive in the first sub-groove 321, thereby improving the stability of the mounting sleeve 40 in the installation groove 31.

[0087] In some embodiments, the glue groove 32 includes a second sub-groove 322 formed on the second frame 34 . The second sub-groove 322 surrounds the outer periphery of the second through hole 36 and communicates with the second through hole 36 .

[0088] Specifically, the second sub-groove 322 is formed on the surface of the second frame 34 and surrounds the outer periphery of the second through hole 36, communicating with the second through hole 36. Thus, after the mounting sleeve 40 passes through the second through hole 36, the mounting sleeve 40 can be fixed in the second through hole 36 by filling the second sub-groove 322 with structural adhesive.

[0089] Through the above structure, the mounting sleeve 40 can be positioned in the installation groove 31 and the mounting sleeve 40 can be adhesively fixed by the structural adhesive in the second sub-groove 322, thereby improving the stability of the mounting sleeve 40 in the installation groove 31.

[0090] It is understood that in a specific embodiment, only the first sub-groove 321 may be provided, and the mounting sleeve 40 may be fixed by gluing using the structural adhesive in the first sub-groove 321. Alternatively, only the second sub-groove 322 may be provided, and the mounting sleeve 40 may be fixed by gluing using the structural adhesive in the second sub-groove 322. Of course, both the first sub-groove 321 and the second sub-groove 322 may be provided, and the structural adhesive in the first and second sub-grooves 321 and 322 may further improve the stability of the mounting sleeve 40 in the installation slot 31.

[0091] In addition, the depth range of the first sub-groove 321 and the second sub-groove 322 can be set to 1mm~5mm. As a specific embodiment, the depth of the first sub-groove 321 and the second sub-groove 322 can be, but is not limited to, set to 1mm, 2mm, 3mm, 4mm, or 5mm.

[0092] like Figure 4 and Figure 7 As shown, in some embodiments, the first frame 33 includes a first body 331 and a first connecting wall 332 connected to each other, the first through hole 35 is opened on the first body 331, and the first connecting wall 332 is used to fit and be fixedly connected to the surface of the box 10.

[0093] Specifically, the first body 331 defines a first through hole 35, that is, the first body 331 is used to connect and fix with the mounting sleeve 40. The first connecting wall 332 can be integrally formed with the first body 331 or connected to the first body 331 by welding.

[0094] The first connecting wall 332 can be used to fit with the surface of the box body 10 to fix the first connecting wall 332 to the box body 10. The first connecting wall 332 and the box body 10 can be connected to each other by welding, but is not limited to welding.

[0095] By providing the first connecting wall 332 , the contact area between the first frame 33 and the box body 10 can be increased, making the connection between the first frame 33 and the box body 10 more stable.

[0096] In some embodiments, the second frame 34 includes a second body 341 and a second connecting wall 342 connected to each other. The second through hole 36 is opened on the second body 341. The second connecting wall 342 is coplanar with the first connecting wall 332 and is used to fit and be fixedly connected to the surface of the box 10.

[0097] Specifically, the second body 341 defines a second through hole 36, that is, the second body 341 is used to connect and fix with the mounting sleeve 40. The second connecting wall 342 can be integrally formed with the second body 341, or can be connected to the second body 341 by welding.

[0098] The second connecting wall 342 can be used to fit with the surface of the box body 10 to fix the second connecting wall 342 to the box body 10. The second connecting wall 342 and the box body 10 can be connected to each other by welding, but is not limited to welding.

[0099] Furthermore, the second connecting wall 342 is coplanar with the first connecting wall 332 , thereby further increasing the overall contact area between the mounting bracket 30 and the box body 10 , making the connection between the mounting bracket 30 and the box body 10 more stable.

[0100] Through the above structure, not only the contact area between the second frame 34 and the box body 10 can be increased, making the connection between the second frame 34 and the box body 10 more stable, but also the overall contact area between the mounting bracket 30 and the box body 10 can be further increased, making the connection between the mounting bracket 30 and the box body 10 more stable.

[0101] In some embodiments, in a direction intersecting the preset direction a and parallel to the first connecting wall 332 or the second connecting wall 342 , the width of the first body 331 and / or the second body 341 gradually increases along the direction in which the mounting sleeve 40 is inserted into the mounting slot 31 .

[0102] Specifically, the direction intersecting the preset direction a and parallel to the first connecting wall 332 or the second connecting wall 342 can be set to be a direction perpendicular to the preset direction a and parallel to the first connecting wall 332. Along the above direction, the width of the first body 331 gradually increases along the direction in which the mounting sleeve 40 is inserted into the installation slot 31, and / or the width of the second body 341 gradually increases along the direction in which the mounting sleeve 40 is inserted into the installation slot 31. In other words, the first body 331 and / or the second body 341 can be configured as a trapezoidal structure whose width gradually increases along the direction in which the mounting sleeve 40 is inserted into the installation slot 31.

[0103] The above structure of the first body 331 and the second body 341 can better meet the requirements of increasing the stress at the bottom of the mounting bracket 30 and increasing the load-bearing area during the mounting process. This can optimize the load-bearing area of the mounting bracket 30 and reduce the probability of cracking in the weld between the mounting bracket 30 and the box body 10.

[0104] like Figure 8 As shown, in some embodiments, a groove 333 is formed on a surface of the first connecting wall 332 facing the box body 10 , and the groove 333 is communicated with the glue groove 32 .

[0105] Specifically, the surface of the first connecting wall 332 facing the box body 10 is actually the surface where the first connecting wall 332 is in contact with the box body 10. A groove 333 is formed on this surface, and the groove 333 is connected to the first sub-groove 321 in the glue groove 32.

[0106] In this way, when the structural adhesive is filled into the first sub-groove 321 , the structural adhesive will flow into the groove 333 , thereby achieving an adhesive connection between the first connecting wall 332 and the box body 10 , further strengthening the connection strength between the mounting bracket 30 and the box body 10 .

[0107] Please see again Figure 7 In some embodiments, a plug welding hole 334 is formed through the first connecting wall 332 .

[0108] Specifically, the first connecting wall 332 may be provided with, but is not limited to, two or more plug welding holes 334 . The specific number of the plug welding holes 334 may be adjusted according to actual use requirements and will not be elaborated herein.

[0109] Through the above structure, the first connecting wall 332 and the box body 10 can be smoothly welded together, thereby improving the connection stability between the two.

[0110] Based on the same concept as the above-mentioned battery device 100 , the present application further provides an electrical device, including the above-mentioned battery device 100 .

[0111] According to one or more embodiments, when the present application is used, first, the specific installation position of the mounting bracket 30 on the box body 10 is determined according to actual needs, and the first connecting wall 332 and the second connecting wall 342 are respectively welded and fixed to the surface of the box body 10 to achieve a fixed connection between the mounting bracket 30 and the box body 10.

[0112] Furthermore, the mounting sleeve 40 is placed into the installation groove 31 , so that the mounting sleeve 40 passes through the second through hole 36 , and the bottom end of the mounting sleeve 40 is supported on the bottom wall of the first sub-groove 321 .

[0113] Structural adhesive is filled into the first and second sub-grooves 321 and 322, covering the entirety of the first and second sub-grooves 321 and 322, thereby gluing and securing the mounting sleeve 40 to the mounting groove 31. Simultaneously, as the structural adhesive is filled into the first sub-grooves 321, it flows into the grooves 333, thereby securing the first connecting wall 332 to the housing 10.

[0114] After the structural adhesive is cured, the mounting sleeve 40 and the mounting bracket 30 as well as the mounting bracket 30 and the box body 10 can be connected and fixed. At this time, the mounting sleeve 40 can be used to connect and fix with the external structure, and the battery device 100 can be installed and fixed to the target position.

[0115] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described.
