Description

Technical Field

[0001] This utility model relates to the field of battery technology, and in particular to a battery device and an electrical device. Background Technology

[0002] With increasing environmental pollution, the new energy industry is attracting more and more attention. Within the new energy industry, battery technology is a crucial factor in its development.

[0003] In related technologies, battery devices are installed on electrical devices, such as on the vehicle frame. However, the fixed installation position of existing battery devices on electrical devices results in poor versatility and makes them unsuitable for various vehicle models. Utility Model Content

[0004] The main purpose of this utility model is to provide a battery device and an electrical device, which can adjust the connection and fixing position with the electrical device according to different electrical devices, thereby improving the versatility of the battery device installation.

[0005] This application provides a battery device, which includes at least one battery cell, a housing, and a mounting assembly. The battery cell is disposed within the housing, and the housing includes a side beam. The mounting assembly includes a mounting member and a mounting sleeve. The mounting member is connected to the side beam and has multiple mounting holes. The mounting sleeve is detachably connected to the mounting member and can be selectively disposed in one of the multiple mounting holes. The mounting sleeve is used to connect to an electrical device.

[0006] In the technical solution of this application embodiment, the box body includes a side beam, and the mounting assembly includes a mounting member and a mounting sleeve. The mounting member is connected to the side beam, and the mounting sleeve is used to connect to the electrical device. The mounting member improves the structural strength of the side beam and ensures the stability of the mounting sleeve installation. The mounting sleeve and the mounting member are detachably connected to facilitate the assembly and disassembly of the mounting sleeve, thereby allowing for the replacement of different specifications of mounting sleeves according to different needs to adapt to different vehicle models. The mounting member is provided with multiple mounting holes, and the mounting sleeve can be selectively located in one of the multiple mounting holes so that the mounting sleeve can be adjusted according to different needs. Its position on the mounting bracket, that is, the adjustable connection position between the mounting sleeve and the electrical device, allows for customization of the connection position with different vehicle models when the battery device needs to be installed on different models. This avoids the situation where the battery device's installation position is fixed and can only be used on one type of vehicle. Furthermore, compared to the direct connection between the mounting sleeve and the side beam, the mounting sleeve in this solution is installed within the mounting hole of the mounting bracket, making the installation position of the mounting sleeve more precise and improving the assembly accuracy of the battery device and the electrical device. Therefore, the battery device of this application can adjust its connection position with different electrical devices, thereby improving the versatility of battery device installation.

[0007] In some embodiments, the side beam has a cavity and a first beam wall and a second beam wall spaced apart along a first direction. The first beam wall and / or the second beam wall are provided with fixing holes communicating with the cavity. At least a portion of the mounting member passes through the fixing holes and the cavity along the first direction, and the mounting member is connected to the first beam wall and / or the second beam wall. In this embodiment, at least a portion of the mounting member passes through the fixing holes and the cavity along the first direction. The fixing holes and the cavity accommodate and enclose the mounting member, and the mounting member is connected to the first beam wall and / or the second beam wall. This improves the connection strength between the mounting member and the side beam, thereby improving the structural strength of the side beam and ensuring the stability and assembly accuracy of the mounting sleeve installation.

[0008] In some embodiments, the first beam wall is provided with the fixing hole, the second beam wall is located below the first beam wall, the hanger is supported on the second beam wall, and the second beam wall is provided with a plurality of through holes communicating with the cavity. These through holes correspond one-to-one with a plurality of mounting holes on the hanger. In this embodiment, the hanger passes through the fixing hole and is installed in the cavity in a top-to-bottom direction. The hanger is supported by the second beam wall, which improves the convenience and stability of the hanger installation. Furthermore, the plurality of through holes on the second beam wall correspond one-to-one with the plurality of mounting holes on the hanger, facilitating the installation of the hanger sleeve and allowing the connector to pass through the hanger sleeve and through holes to fix the side beam to the electrical device.

[0009] In some embodiments, the cross-sectional area of ​​the through hole is smaller than the cross-sectional area of ​​the mounting hole, and the mounting sleeve is disposed within the mounting hole and supported on the second beam wall; and / or, the mounting member is welded and fixed to the first beam wall. In this embodiment, the opening cross-sectional area of ​​the through hole is smaller than the opening cross-sectional area of ​​the mounting hole, and the through hole communicates with the mounting hole, so that the second beam wall at the periphery of the through hole can support the mounting sleeve, that is, limit the positioning of the mounting sleeve, thus improving the convenience and stability of the mounting sleeve installation. This solution only requires welding the mounting member to the first beam wall, without welding the mounting member to the second beam wall, so that the mounting member can be stably installed on the side beam. The fixing method of the mounting member is simple and helps to reduce the assembly difficulty of the battery device.

[0010] In some embodiments, multiple mounting holes on the mount are spaced apart along the length of the side beam. This arrangement allows the mounting sleeve to be adjusted in position on the mount according to different needs along the length of the side beam. Specifically, it allows adjustment of the connection position between the mounting sleeve and the electrical device along the length of the side beam. When the battery device needs to be installed on different vehicle models, the connection position with different vehicle models can be adjusted by changing the position of the mounting sleeve in the multiple mounting holes along the length of the side beam. This avoids the situation where the battery device's installation position is fixed and can only be adapted to one type of vehicle, thereby improving the versatility of battery device installation.

[0011] In some embodiments, the distance between two adjacent mounting holes on the mounting component is not less than 10 mm and not more than 80 mm. In this embodiment, by limiting the distance between two adjacent mounting holes, the mounting sleeve can be adjusted to a suitable installation position on the mounting component, thereby facilitating a stable connection and fixation between the mounting sleeve and different electrical devices.

[0012] In some embodiments, the mounting sleeve includes a sleeve body and a limiting portion disposed on the outer peripheral wall of the sleeve body. The limiting portion is supported on the mounting member, and the sleeve body is disposed within the mounting hole and detachably connected to the mounting member. In this embodiment, the limiting portion is supported on the mounting member, thereby limiting the installation of the mounting sleeve and improving the stability of the mounting sleeve installation. Furthermore, the sleeve body is detachably connected to the mounting member, facilitating the assembly and disassembly of the mounting sleeve. This allows for the replacement of different specifications of mounting sleeves according to different needs, to adapt to different vehicle models.

[0013] In some embodiments, the outer peripheral wall of the sleeve body is provided with external threads, and the wall of the mounting hole is provided with internal threads, and the sleeve body is threadedly connected to the mounting member; and / or, the mounting sleeve is provided with an assembly hole that extends along a first direction, the assembly hole being used for the connector to pass through. In this embodiment, the sleeve body and the mounting member are threadedly connected, the structure of the sleeve body and the mounting member is simple, and the connection is convenient, making it easy to stably install the mounting sleeve on the mounting member, reducing the manufacturing difficulty of the mounting sleeve, and improving the assembly efficiency of the battery device. The mounting sleeve is provided with an assembly hole, allowing the connector to pass through the assembly hole and connect to the electrical device, making it easy to stably fix the housing to the electrical device.

[0014] In some embodiments, the battery device includes a plurality of mounting components, which are spaced apart along the length of the side beam. Each mounting component has at least two mounting holes on its mounting member. In this embodiment, the battery device includes a plurality of mounting components, each comprising a plurality of mounting members and a plurality of mounting sleeves. Along the length of the side beam, the positions of the mounting sleeves on the mounting members can be adjusted according to different needs. That is, the positions of the mounting sleeves connected to the electrical device along the length of the side beam are adjustable, thereby allowing for flexible adjustment of the locking position between the housing and the electrical device to adapt to different vehicle models. This avoids the situation where the installation position of the battery device is fixed and can only adapt to one type of vehicle, thus improving the versatility of battery device installation.

[0015] In some embodiments, the distance between two adjacent mounting components is not less than 60mm and not more than 200mm. In this embodiment, by limiting the distance between two adjacent mounting components, the distance between two adjacent mounting sleeves is effectively limited, ensuring that the installation distance between two adjacent mounting sleeves is within a suitable range. This is beneficial for improving the stability of connecting multiple mounting sleeves with different electrical devices.

[0016] This application also proposes an electrical device that includes a battery device for storing or providing electrical energy.

[0048] In some embodiments, the housing 200 may include a first portion 220 and a second portion 230, which overlap each other, and together define a receiving space for accommodating the battery cell 100. The second portion may be a hollow structure with one open end, and the first portion may be a plate-like structure, with the first portion covering the open side of the second portion so that the first and second portions together define the receiving space. Alternatively, the first portion 220 and the second portion 230 may both be hollow structures with one open side, with the open side of the first portion 220 covering the open side of the second portion 230. Of course, the housing 200 formed by the first portion 220 and the second portion 230 can be of various shapes, such as a cylinder, a cuboid, etc.

[0049] In some embodiments, the housing 200 includes a side beam 210, and the side beam 210 is provided on the periphery of the first portion 220 and / or the second portion 230.

[0050] In a battery device, there can be multiple battery cells, which can be connected in series, parallel, or a combination thereof. A combination thereof means that multiple battery cells are connected in both series and parallel configurations. Multiple battery cells can be directly connected in series, parallel, or a combination thereof, and then the entire assembly of these battery cells is housed within a casing. Alternatively, the battery device can consist of multiple battery cells first connected in series, parallel, or a combination thereof to form battery modules, and then these modules are connected in series, parallel, or a combination thereof to form a whole, which is also housed within a casing.

The mounting sleeve 320 is detachably connected to the mounting member 310 and can be selectively disposed in one of the multiple mounting holes 311. The mounting sleeve 320 is used to connect to an electrical device.

[0057] The housing 200 may include a first portion 220 and a second portion 230, which overlap each other and together define a receiving space for accommodating the battery cell 100. The housing 200 also includes side beams 210, which are load-bearing components constituting the side frame or reinforcing structure of the housing 200. The side beams 210 are typically located on both sides of the housing 200 along its length. For example, the side beams 210 are located on the outer surfaces of the first portion 220 and / or the second portion 230, and the side beams 210 reinforce the first portion 220 and / or the second portion 230 to improve the structural strength of the housing 200.

[0058] Figure 3 The first direction is the height direction of the battery device 10, and the second direction is the length direction of the battery device 10. The side beam 210 can extend along the second direction. Of course, the side beam 210 can also be arranged around the periphery of the housing 200, which is not limited here.

[0059] The mounting assembly 300 includes a mounting member 310 and a mounting sleeve 320. The mounting sleeve 320 is used to connect to an electrical device; that is, the mounting sleeve 320 is a structural component connecting the battery device 10 to the electrical device, such as the vehicle frame or body of the vehicle 1. The mounting member 310 and the side beam 210 can be fixedly connected or detachably connected, which is not limited here. For example, the mounting member 310 and the side beam 210 can be welded and fixed, or the mounting member 310 and the side beam 210 can be snapped together, or the mounting member 310 and the side beam 210 can be threaded together.

[0060] The mounting component 310 has multiple mounting holes 311. The arrangement of the mounting holes 311 is not limited, such as, but not limited to: the multiple mounting holes 311 are arranged linearly, or arranged in an array, or arranged circumferentially, or arranged in an alternating pattern, etc. The mounting sleeve 320 can be detachably connected to the mounting component 310 in various ways, such as, but not limited to: snap-fit ​​connection, threaded connection, etc.

[0061] The mounting component 310 is provided with multiple mounting holes 311, and the mounting sleeve 320 can be selectively provided in one of the multiple mounting holes 311, so that the position of the mounting sleeve 320 on the mounting component 310 is adjustable. The mounting sleeve 320 is used to connect with the electrical device, that is, the mounting sleeve 320 can be adjusted to connect with the electrical device, thus avoiding the situation that the mounting position of the mounting sleeve 320 is fixed and can only be adapted to one type of electrical device.

[0062] The side beam 210 can be made of metal materials, including but not limited to aluminum, aluminum alloys, steel, and stainless steel. The mounting component 310 can be made of metal materials, including but not limited to aluminum, aluminum alloys, copper, iron, steel, and stainless steel. The mounting sleeve 320 can be made of metal materials, including but not limited to aluminum, aluminum alloys, copper, iron, steel, and stainless steel.

[0063] The number of mounting components 300 is not limited and can be one or more, including two. When there is only one mounting component 300, the mounting member 310 can extend along the length of the side beam 210, and the mounting sleeve 320 can be selectively disposed in one of the multiple mounting holes 311. When there are multiple mounting components 300, the multiple mounting components 300 include multiple mounting members 310 and multiple mounting sleeves 320. The multiple mounting members 310 can be spaced apart along the length of the side beam 210, and each mounting sleeve 320 is disposed in the mounting hole 311 of the corresponding mounting member 310. When there is one or more mounting components 300, the mounting component 310 is provided with multiple mounting holes 311, and the mounting sleeve 320 can be selectively provided in one of the multiple mounting holes 311 so that the mounting sleeve 320 can be adjusted on the mounting component 310 according to different needs, that is, the position of the mounting sleeve 320 connected to the electrical device can be adjusted, so that it can be installed on different electrical devices to adapt to different vehicle models.

[0064] In the technical solution of this application embodiment, the housing 200 includes a side beam 210, and the mounting assembly 300 includes a mounting member 310 and a mounting sleeve 320. The mounting member 310 is connected to the side beam 210, and the mounting sleeve 320 is used to connect to an electrical device. The mounting member 310 improves the structural strength of the side beam 210 and ensures the stability of the mounting sleeve 320 during installation. The mounting sleeve 320 is detachably connected to the mounting member 310 to facilitate the assembly and disassembly of the mounting sleeve 320, thereby allowing for the replacement of different specifications of the mounting sleeve 320 according to different needs to adapt to different vehicle models 1. The mounting member 310 is provided with multiple mounting holes 311, and the mounting sleeve 320 can be selectively disposed in one of the multiple mounting holes 311, so that the mounting sleeve... The position of the mounting sleeve 320 on the mounting bracket 310 can be adjusted according to different needs, that is, the connection position between the mounting sleeve 320 and the electrical device can be adjusted. When the battery device 10 needs to be installed on different vehicle models, the connection position with different vehicle models can be adjusted by adjusting the position of the mounting sleeve 320 in multiple mounting holes 311 to adapt to different vehicle models. This avoids the situation where the installation position of the battery device 10 is fixed and can only be adapted to one type of vehicle model. Furthermore, compared to the direct connection between the mounting sleeve 320 and the side beam 210, the mounting sleeve 320 of this solution is installed in the mounting hole 311 of the mounting bracket 310, making the installation position of the mounting sleeve 320 more precise and improving the assembly accuracy of the battery device 10 and the electrical device. Therefore, the battery device 10 of this application can adjust the fixed connection position with the electrical device according to different electrical devices, thereby improving the versatility of the battery device 10 installation.

[0065] Please see Figures 3 to 5 According to some embodiments of this application, optionally, the side beam 210 has a cavity 211 and a first beam wall 212 and a second beam wall 213 spaced apart along a first direction. The first beam wall 212 and / or the second beam wall 213 are provided with fixing holes 214 communicating with the cavity 211. At least a portion of the mounting member 310 passes through the fixing hole 214 and the cavity 211 along the first direction, and the mounting member 310 is connected to the first beam wall 212 and / or the second beam wall 213.

[0066] The specific direction of the first direction is not limited. For example, the first direction can be the height direction of the battery device 10, or it can be the length direction of the battery device 10. In this embodiment, the first direction is the height direction of the battery device 10, that is, the first beam wall 212 and the second beam wall 213 are spaced apart along the height direction of the battery device 10. The side beam 210 has a cavity 211, which can be a polygonal closed cavity structure that runs continuously along the length direction of the side beam 210. The side beam 210 also includes a side wall beam, which connects the first beam wall 212 and the second beam wall 213. The cavity 211 is formed by the first beam wall 212, the second beam wall 213 and the side wall beam. The cavity 211 is beneficial for achieving lightweighting, and at the same time, the cavity structure improves the load-bearing efficiency of the side beam 210. When a collision occurs, the cavity 211 can undergo collapse deformation to absorb the impact kinetic energy and prevent the colliding object from entering the receiving cavity of the housing 200.

[0067] Fixing holes 214 are provided on the first beam wall 212 and / or the second beam wall 213. The shape of the fixing holes 214 is not limited, such as but not limited to: circular through holes, square through holes, polygonal through holes, irregular through holes, etc. At least part of the mounting member 310 is inserted into the fixing holes 214 and the cavity 211 along the first direction, that is, the mounting member 310 is installed in the fixing holes 214 and the cavity 211 along the first direction. The fixing holes 214 and the cavity 211 can accommodate and enclose the mounting member 310. In this embodiment, the mounting member 310 is installed in the fixing holes 214 and the cavity 211 in a top-to-bottom direction, which facilitates the installation of the mounting member 310. Furthermore, the mounting member 310 is connected to the first beam wall 212 and / or the second beam wall 213, so that the mounting member 310 can be stably installed in the side beam 210.

[0068] In this embodiment, at least a portion of the mounting member 310 is inserted into the fixing hole 214 and the cavity 211 along the first direction. The fixing hole 214 and the cavity 211 accommodate and enclose the mounting member 310, and the mounting member 310 is connected to the first beam wall 212 and / or the second beam wall 213. This improves the connection strength between the mounting member 310 and the side beam 210, thereby improving the structural strength of the side beam 210 and ensuring the stability and assembly accuracy of the mounting sleeve 320.

[0069] Please see Figures 3 to 5 According to some embodiments of this application, optionally, the first beam wall 212 is provided with a fixing hole 214, the second beam wall 213 is located below the first beam wall 212, the hanger 310 is supported on the second beam wall 213, the second beam wall 213 is provided with a plurality of through holes 215 communicating with the cavity 211, and the plurality of through holes 215 are connected to the plurality of mounting holes 311 on the hanger 310 in a one-to-one correspondence.

[0070] The second beam wall 213 is located below the first beam wall 212 along its height direction. The mounting member 310 passes through the fixing hole 214 along the first direction and is disposed in the cavity 211. The bottom end of the mounting member 310 is supported by the second beam wall 213, which supports the mounting member 310 and ensures the stability of the mounting member 310 installation. The second beam wall 213 is provided with multiple through holes 215, which communicate with the mounting hole 311. The through holes 215 not only help to reduce the weight of the side beam 210, but also allow the mounting sleeve 320 and / or connector to pass through and connect to the electrical device, thus improving the convenience of installing the battery device 10 on the electrical device. The size and shape of the through holes 215 are not limited, for example, but not limited to: the through holes 215 are circular, square, polygonal, or irregular in shape, etc.

[0071] In this embodiment, the mounting member 310 passes through the fixing hole 214 in a downward direction and is installed in the cavity 211. The mounting member 310 is supported by the second beam wall 213, which improves the convenience and stability of the mounting member 310 installation. Furthermore, the multiple through holes 215 on the second beam wall 213 correspond one-to-one with the multiple mounting holes 311 on the mounting member 310, so as to facilitate the installation of the mounting sleeve 320 and also to facilitate the connection member to pass through the mounting sleeve 320 and the through holes 215 to fix the side beam 210 to the electrical device.

[0072] According to some embodiments of this application, optionally, the cross-sectional area of ​​the through hole 215 is smaller than the cross-sectional area of ​​the mounting hole 311, and the mounting sleeve 320 is disposed in the mounting hole 311 and supported on the second beam wall 213.

[0073] The shapes of the through hole 215 and the mounting hole 311 are not limited, as long as the cross-sectional area of ​​the through hole 215 is smaller than the cross-sectional area of ​​the mounting hole 311. In this embodiment, both the through hole 215 and the mounting hole 311 are circular, which facilitates processing.

[0074] In this embodiment, the cross-sectional area of ​​the through hole 215 is smaller than that of the mounting hole 311. The through hole 215 is connected to the mounting hole 311, so that the second beam wall 213 at the periphery of the through hole 215 can support the mounting sleeve 320, that is, limit the mounting sleeve 320, thus improving the convenience and stability of the mounting sleeve 320 installation.

[0075] According to some embodiments of this application, optionally, the mounting member 310 is welded and fixed to the first beam wall 212. Specifically, welding can be performed along the periphery of the fixing hole 214 to the outer peripheral wall of the mounting member 310 to improve the structural strength and sealing of the side beam 210, while also enhancing the stability of the mounting member 310 during installation.

[0076] This solution only requires welding the mounting component 310 to the first beam wall 212, without welding the mounting component 310 to the second beam wall 213, so that the mounting component 310 can be stably installed on the side beam 210. The fixing method of the mounting component 310 is simple, which helps to reduce the assembly difficulty of the battery device 10.

[0077] According to some embodiments of this application, optionally, the side beam 210 further includes a third beam wall, which is located below and spaced apart from the second beam wall 213, and the second beam wall and the third beam wall are connected by side wall beams. It is understood that the second beam wall, the third beam wall, and the side wall beams together form part of a cavity. In this embodiment, the structural strength of the side beam is further increased by providing the third beam wall.

[0078] According to some embodiments of this application, optionally, a through hole is provided on the third beam wall for the connector to pass through. By providing a through hole on the third beam wall, the side beam 210 is fixed to the electrical device so that the connector can pass through the mounting sleeve 320, the through hole 215 and the through hole.

[0079] Please see Figures 3 to 6 According to some embodiments of this application, optionally, a plurality of mounting holes 311 on the mount 310 are spaced apart along the length direction of the side beam 210. The length direction of the side beam 210 can be... Figure 5 In the second direction, that is, multiple mounting holes 311 can be arranged at intervals along the length of the housing 200. The mounting sleeve 320 can be selectively provided in one of the multiple mounting holes 311, so that the position of the mounting sleeve 320 on the side beam 210 is adjustable, avoiding the fixed connection position of the mounting sleeve 320. That is, the connection position of the mounting sleeve 320 and the electrical device can be adjusted along the length of the housing 200, thereby adapting to different vehicle models and improving the universality of the battery device 10 installation.

[0080] In this embodiment, along the length of the side beam 210, the mounting sleeve 320 can be adjusted on the mounting member 310 according to different needs. That is, the position of the mounting sleeve 320 connected to the electrical device can be adjusted along the length of the side beam 210. When the battery device 10 needs to be installed on different vehicle models, the position of the mounting sleeve 320 in the multiple mounting holes 311 can be adjusted along the length of the side beam 210 to adapt to different vehicle models. This avoids the situation where the installation position of the battery device 10 is fixed and can only be adapted to one type of vehicle model, thereby improving the universality of the installation of the battery device 10.

[0081] According to some embodiments of this application, optionally, the distance between two adjacent mounting holes 311 on the mount 310 is not less than 10mm and not more than 80mm. The distance between two adjacent mounting holes 311 can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, or 80mm, or any value within the above range.

[0082] In this embodiment, by limiting the distance between two adjacent mounting holes 311, the mounting sleeve 320 is adjusted to a suitable mounting position on the mounting member 310, thereby facilitating a stable connection and fixation between the mounting sleeve 320 and different electrical devices.

[0083] Please see Figures 5 to 7 According to some embodiments of this application, optionally, the mounting sleeve 320 includes a sleeve body 321 and a limiting part 322 provided on the outer peripheral wall of the sleeve body 321. The limiting part 322 is supported on the mounting member 310. The sleeve body 321 is provided in the mounting hole 311 and is detachably connected to the mounting member 310.

[0084] The limiting part 322 can be a complete ring or an intermittent ring on the outer peripheral wall of the sleeve body 321, or it can simply protrude from the outer peripheral wall of the sleeve body 321. The limiting part 322 only needs to be able to support the mounting member 310. In other words, by setting the limiting part 322, the mounting sleeve 320 can be quickly positioned and installed, improving the convenience of installation. The sleeve body 321 and the mounting member 310 can be detachably connected in various ways, such as, but not limited to, snap-fit ​​connections and threaded connections.

[0085] In this embodiment, the limiting part 322 is supported on the mounting member 310. The limiting part 322 limits the installation of the mounting sleeve 320, thereby improving the stability of the mounting sleeve 320 installation. The sleeve body 321 is detachably connected to the mounting member 310, so as to facilitate the assembly and disassembly of the mounting sleeve 320. This allows for the replacement of different specifications of the mounting sleeve 320 according to different needs, in order to adapt to different vehicle models.

[0086] According to some embodiments of this application, optionally, the outer peripheral wall of the sleeve body 321 is provided with an external thread 324, the wall of the mounting hole 311 is provided with an internal thread, and the sleeve body 321 is threadedly connected to the hanger 310.

[0087] The sleeve body 321 is threadedly connected to the internal thread in the mounting hole 311 of the hanger 310 via the external thread 324, which facilitates the assembly and disassembly of the sleeve body 321 and ensures the stability of the hanger sleeve 320 during installation.

[0088] In this embodiment, the sleeve body 321 is threadedly connected to the mounting component 310. The sleeve body 321 and the mounting component 310 have simple structures and are easy to connect, making it easy to stably install the mounting sleeve 320 on the mounting component 310. This reduces the manufacturing difficulty of the mounting sleeve 320 and helps to improve the assembly efficiency of the battery device 10.

[0089] According to some embodiments of this application, optionally, the mounting sleeve 320 is provided with an assembly hole 323 that extends along a first direction, and the assembly hole 323 is used for the connection to pass through.

[0090] The first direction can be the height direction of the battery device 10, which is also the axial direction of the mounting sleeve 320. The mounting hole 323 penetrates the mounting sleeve 320 along the height direction of the battery device 10. The size and shape of the mounting hole 323 are not limited, for example but not limited to, a circular through hole, a square through hole, a polygonal through hole, an irregular through hole, etc.

[0091] When the mounting sleeve 320 is installed in the mounting hole 311, the assembly hole 323 is connected to the corresponding through hole 215 on the second beam wall 213. This arrangement allows the connector to pass through the assembly hole 323 and be connected and fixed to the external electrical device.

[0092] In this embodiment, the mounting sleeve 320 is provided with an assembly hole 323, which allows the connector to pass through the assembly hole 323 and connect to the electrical device, facilitating the stable fixing of the housing 200 to the electrical device. For example, the connector is a bolt.

[0093] According to some embodiments of this application, optionally, the battery device 10 includes a plurality of mounting components 300, which are spaced apart along the length of the side beam 210, and each mounting component 300 has at least two mounting holes 311 on its mounting member 310.

[0094] It is understood that multiple mount components 300 include two mount components 300, that is, the number of mount components 300 can be two, three, four, etc., and the specific number is not limited here.

[0095] In this embodiment, the battery device 10 includes multiple mounting components 300, each including multiple mounting parts 310 and multiple mounting sleeves 320. Along the length of the side beam 210, the multiple mounting sleeves 320 can adjust their positions on the multiple mounting parts 310 according to different needs. That is, the positions of the multiple mounting sleeves 320 connected to the electrical device along the length of the side beam 210 are adjustable, thereby flexibly adjusting the locking position between the housing 200 and the electrical device to adapt to different vehicle models. This avoids the situation where the installation position of the battery device 10 is fixed and can only adapt to one type of vehicle model, thereby improving the universality of the battery device 10 installation.

[0096] According to some embodiments of this application, optionally, the distance between two adjacent mounting pieces 310 is not less than 60mm and not more than 200mm. The distance between two adjacent mounting pieces 310 can be 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, or 200mm, or any value within the above range.

[0097] In this embodiment, by limiting the distance between two adjacent mounting parts 310, the distance between two adjacent mounting sleeves 320 is effectively limited, so that the installation distance between two adjacent mounting sleeves 320 is within a suitable range, which helps to improve the stability of the connection between multiple mounting sleeves 320 and different electrical devices.
