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] To facilitate battery device installation, such as on a vehicle, a mounting structure is typically provided on the battery device, connecting the mounting structure to the vehicle body for secure installation. However, limitations in conventional battery device design result in relatively insufficient mechanical strength at the mounting point, which impacts the reliability of the battery device's installation. Utility Model Content

[0003] Based on this, it is necessary to provide a battery device and electrical equipment to enhance the mechanical strength of the mounting point and improve the reliability of the battery device installation.

[0004] In the first aspect, the present application provides a battery device, which includes: a battery cell; a frame, an interior of which forms a storage space, and the battery cell is accommodated in the storage space, the frame including a support beam located on one side of a preset direction of the battery cell; a first mounting member, which is arranged on the support beam and is an integrated structure with the support beam; wherein a reinforcement channel is provided through the first mounting member, and the extension direction of the reinforcement channel, the length direction of the support beam and the preset direction intersect with each other and the three are not coplanar.

[0005] The battery assembly described above has a first mounting member integrally formed on the support beam, which helps strengthen the bonding force between the first mounting member and the support beam. Furthermore, the reinforcing channel provided on the first mounting member extends in a direction that intersects with the length of the support beam and the predetermined direction. Therefore, when the battery assembly is mounted in an electrical device via the first mounting member, the reinforcing channel extends in the overall height direction of the device. This facilitates the transmission of impact or vibration forces along the intersecting extension and length directions, resulting in higher impact or shock resistance, enhanced mechanical strength of the mounting point, and improved battery assembly installation reliability.

[0006] In some embodiments, the first mounting member is further provided with an installation channel, the reinforcement channel being located on one side of the installation channel, and the installation channel being used for passing the fastener. This design and the introduction of the installation channel facilitate the fastening of the first mounting member with the fastener, thereby improving installation efficiency.

[0007] In some embodiments, the first mounting member includes a main body and a mounting protrusion protruding from the main body along a predetermined direction. The reinforcement channel is provided in the main body and / or the mounting protrusion, the mounting channel is provided in the mounting protrusion, and the side of the main body facing away from the mounting protrusion is provided on the support beam. This design shifts the fixing point on the first mounting member to the mounting protrusion, leaving more space for fasteners to secure the first mounting member and improving the convenience of installing the first mounting member.

[0008] In some embodiments, the mounting protrusion includes a first end surface and a second end surface at each end along the extension direction of the reinforcement channel. One end of the main body extends beyond the second end surface along the extension direction, and the mounting channel extends through the first and second end surfaces. This design, in which one end of the main body extends beyond the second end surface, shields one end of the fastener inserted into the mounting channel, reducing the likelihood of exposed components and making the overall structure more compact.

[0009] In some embodiments, the reinforcement channel partially extends onto the surface of the main body facing the mounting protrusion, forming a first protrusion on the main body. This design, by extending the reinforcement channel partially onto the surface of the main body, allows the formed first protrusion to enhance the structural strength of the main body surface, thereby improving the overall structural mechanical strength of the first mounting component.

[0010] In some embodiments, the first mounting member further includes a fixing protrusion, which is located on the body portion facing away from the mounting protrusion. The fixing protrusion and the support beam are integrally formed. This design, with the introduction of the fixing protrusion, facilitates a tight connection between the first mounting member and the support beam. Furthermore, positioning the fixing protrusion on the side of the body portion facing away from the mounting protrusion allows the mounting protrusion to be further away from the support beam, further enhancing the ease of installation of the first mounting member.

[0011] In some embodiments, the fixing protrusion includes a third end surface adjacent to the mounting protrusion, and one end of the main body extends beyond the third end surface along the extension direction of the reinforcement channel. This design not only saves material but also provides operating space for fixing the mounting protrusion.

[0012] In some embodiments, at least a portion of the reinforcement channel is provided on the third end surface and extends to the surface of the main body facing the fixing protrusion, thereby forming a second protrusion on the main body. This design extends the reinforcement channel to the surface of the main body, thereby forming a second protrusion that enhances the structural strength of the main body surface, thereby improving the overall structural mechanical strength of the first mounting component.

[0013] In some embodiments, there are multiple reinforcement channels, and at least some of the reinforcement channels are spaced apart around the periphery of the mounting channel. This design enhances the structural strength of the periphery of the mounting channel and helps improve the stability of the mounting.

[0014] In some embodiments, the battery assembly further includes a second mounting member. A fixing hole is defined on at least one end of the frame along the length of the support beam, and the second mounting member is inserted into the fixing hole. This design, including the second mounting member, increases the number of mounting points for the battery assembly in different directions, thereby improving the installation stability of the battery assembly.

[0015] In some embodiments, the first mounting member extends beyond one end surface of the support beam along the extension direction of the reinforcement channel. This design makes it easier for the first mounting member to contact the installation location, facilitating fixed installation of the battery device.

[0016] In some embodiments, the frame includes two longitudinal beams, two transverse beams, and two diagonal beams. The two longitudinal beams are arranged side by side and spaced apart. One transverse beam is connected between the ends of the two longitudinal beams on one side, and both ends of the other transverse beam are connected to the ends of the two longitudinal beams on the other side via diagonal beams to enclose a storage space. At least one of each longitudinal beam, each transverse beam, and each diagonal beam serves as a support beam. This design facilitates the installation of a first mounting member on the frame, improving mounting stability.

[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

[0030] 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.

[0031] In electrical equipment, batteries are typically mounted using mounting structures. For example, they are secured to vehicles to protect against vibration and impact during driving. However, limitations in the design of these mounting structures result in relatively insufficient mechanical strength at the mounting points. This can lead to structural instability under significant impact or vibration, compromising the reliability of the battery installation.

[0032] Based on this, and addressing the relatively insufficient mechanical strength of the mounting point in traditional battery devices, the present application provides a battery device in which a first mounting member is integrally formed on the support beam, which is conducive to enhancing the bonding force between the first mounting member and the support beam. At the same time, the extension direction of the reinforcement channel provided on the first mounting member intersects with the length direction of the support beam and the preset direction. Therefore, when the battery device is installed in the electrical equipment through the first mounting member, the extension direction of the reinforcement channel is the overall height direction of the electrical equipment. This facilitates the transmission of impact or vibration forces in the intersecting extension direction and length direction, has high impact or shock resistance, enhances the mechanical strength of the mounting point, and improves the reliability of the battery device installation.

[0033] 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.

[0034] 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.

[0035] 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.

[0036] 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.

[0037] 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 .

[0038] Please refer to Figure 2 , Figure 2An 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 being housed in the housing 20. The housing 20 is used to provide a storage space 11 for the battery cell 10, and the housing 20 can adopt a variety of structures. In some embodiments, the housing 20 can include a first portion 201 and a second portion 202, the first portion 201 and the second portion 202 covering each other, and the first portion 201 and the second portion 202 jointly defining a storage space 11 for accommodating the battery cell 10. The second portion 202 can be a hollow structure with one end open, and the first portion 201 can be a plate-like structure, with the first portion 201 covering the open side of the second portion 202, so that the first portion 201 and the second portion 202 jointly define the storage space 11; the first portion 201 and the second portion 202 can also be hollow structures with one side open, with the open side of the first portion 201 covering the open side of the second portion 202. Of course, the box body 20 formed by the first part 201 and the second part 202 can be in various shapes, such as a cylinder, a cuboid, etc.

[0039] 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.

[0040] 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.

[0041] According to some embodiments of this application, please refer to Figure 3 and Figure 4The present application provides a battery device 100, comprising: a battery cell 10, a frame 1, and a first mounting member 2. The frame 1 defines an interior housing 11, wherein the battery cell 10 is accommodated in the housing 11. The frame 1 includes a support beam 12 located on one side of the battery cell 10 in a preset direction Z. The first mounting member 2 is disposed on the support beam 12 and forms an integrated structure therewith. A reinforcement channel 21 is provided through the first mounting member 2. The extension direction X of the reinforcement channel 21, the length direction Y of the support beam 12, and the preset direction Z intersect with each other and are not coplanar.

[0042] The frame 1 is an annular structure with a storage space 11 within it. Its specific shape can be various, including, but not limited to, circular, oval, square, pentagonal, and hexagonal. To facilitate the stable storage of the battery cells 10 within the energy storage space, the battery cells 10 may also include a base 3. The frame 1 is mounted on the base 3 to form the second portion 202 of the housing 20. The battery cells 10 within the storage space 11 are supported on the base 3. Furthermore, the support beam 12 refers to a portion of the frame 1 located outside the storage space 11.

[0043] The first mounting part 2 refers to a structure for fixing the battery device 100 in the electrical equipment, and it is an integrated structure with the support beam 12. There are many ways to form the first mounting part 2 and the support beam 12, such as but not limited to die casting, extrusion, 3D printing and other technologies. Specifically in some examples, the first mounting part 2 and the support beam 12 are an integral extrusion molding structure. At the same time, there are also many settings for the first mounting part 2 on the support beam 12, such as: the first mounting part 2 can be set on the side of the support beam 12 facing away from the accommodating space 11; it can also be set on the top surface of the support beam 12, etc. In addition, the number of first mounting parts 2 can be one or more. When the number of first mounting parts 2 is more than one, at least some of the first mounting parts 2 can be distributed at intervals along the length direction Y of the support beam 12.

[0044] Since the extension direction X of the reinforcing channel 21, the length direction Y of the support beam 12, and the preset direction Z intersect with each other, when the first mounting member 2 and the support beam 12 are extruded as a single piece, the extension direction X of the reinforcing channel 21 is the extrusion direction of the first mounting member 2. For ease of understanding, the vehicle 1000 is used as an example. When the battery device 100 is installed on the vehicle, the first mounting member 2 is fixed in the vehicle 1000. At this time, the extension direction X of the reinforcing channel 21 is the overall height direction of the vehicle 1000, which facilitates the transmission of impact or vibration forces in the extension direction X. At the same time, part of the impact or vibration force can also be transmitted and diffused in the length direction Y that intersects with the extension direction X, which can provide effective impact resistance or shock resistance and enhance the mechanical strength of the mounting point. Specifically, in some examples, the extension direction X of the reinforcing channel 21, the length direction Y of the support beam 12, and the preset direction Z are perpendicular to each other.

[0045] The reinforcement channel 21 extends through the first mounting member 2, forming a reinforcement structure on the first mounting member 2 to enhance the structural strength of the first mounting member 2 along the extension direction X of the reinforcement channel 21. The number of reinforcement channels 21 can be one or more. Furthermore, the first mounting member 2 can be installed in the electrical equipment in a variety of ways, such as, but not limited to, riveting and bolting.

[0046] In addition, the first mounting member 2 may or may not exceed the top surface of the support beam 12. When one end of the first mounting member 2 exceeds the top surface of the support beam 12, the first mounting member 2 can more easily contact the assembly surface of the electrical device, thereby improving the convenience of installation.

[0047] Such a design facilitates the transmission of impact or vibration forces in the intersecting extension direction X and length direction Y, thus having higher impact or vibration resistance, enhancing the mechanical strength of the mounting point, and improving the installation reliability of the battery device 100 .

[0048] According to some embodiments of the present application, optionally, please refer to Figure 4 The first mounting member 2 is further provided with an installation channel 22 , and the reinforcement channel 21 is located on one side of the installation channel 22 , and the installation channel 22 is used for fasteners to pass through.

[0049] The mounting channel 22 allows for the insertion of a fastener, allowing the fastener to secure the first mounting member 2 to the electrical device. The mounting channel 22 can be a blind hole or a through-hole. If the mounting channel 22 is a blind hole, threads or an embedded nut can be provided within the mounting channel 22. If the mounting channel 22 is a through-hole, one end of the fastener can be passed through the mounting channel 22 and connected to a nut or other component, while the other end can be connected to a structure within the electrical device. The fastener can be, but is not limited to, a rivet or bolt.

[0050] To facilitate the operation of the fastener, the installation channel 22 can be set on the side of the reinforcement channel 21 away from the support beam 12, so that the fastener is kept away from the frame 1 and more space is provided for its fixing operation.

[0051] With such a design, the installation channel 22 is introduced, which facilitates the fixation of the first mounting component 2 by fasteners, thereby improving installation efficiency.

[0052] According to some embodiments of the present application, optionally, please refer to Figure 4 The first mounting component 2 includes a main body 23 and a mounting protrusion 24 protruding from the main body 23 along a preset direction Z, the reinforcement channel 21 is provided on the main body 23 and / or the mounting protrusion 24, the mounting channel 22 is provided on the mounting protrusion 24, and the side of the main body 23 facing away from the mounting protrusion 24 is provided on the support beam 12.

[0053] It can be seen that the fixing point on the first mounting part 2 is transferred to the mounting protrusion 24. In this way, during the installation process, the fastener can be inserted into the mounting channel 22 on the mounting protrusion 24, so that the mounting protrusion 24 is fixed in the electrical equipment through the fastener.

[0054] Because the mounting protrusion 24 protrudes from the main body 23 along the predetermined direction Z, and the side of the main body 23 facing away from the mounting protrusion 24 is disposed on the support beam 12, the mounting protrusion 24 is relatively further away from the support beam 12, making installation of the first mounting member 2 more convenient. The main body 23 can be directly integrally mounted on the support beam 12, or indirectly integrally mounted on the support beam 12 via an intermediate structure.

[0055] With this design, the fixing point on the first mounting component 2 is transferred to the mounting protrusion 24 , leaving more space for the fixing operation of the fastener, thereby improving the convenience of installing the first mounting component 2 .

[0056] According to some embodiments of the present application, optionally, please refer to Figure 4 and Figure 5 The mounting protrusion 24 includes a first end surface 241 and a second end surface 242 at both ends along the extension direction X of the reinforcement channel 21, and one end of the main body 23 extends beyond the second end surface 242 along the extension direction X. The mounting channel 22 passes through the first end surface 241 and the second end surface 242.

[0057] As can be seen, a stepped structure is formed between the main body 23 and the second end surface 242. When the fastener is inserted into the mounting channel 22, one end of the fastener is shielded by the main body 23 and does not extend beyond the end of the main body 23, thereby reducing the exposure of the component. This also helps reduce the material used for the mounting protrusion 24 and reduces the overall weight of the first mounting component 2.

[0058] When the electrical device is a vehicle 1000, the first end face 241 can be aligned with the assembly surface of the vehicle 1000, allowing the first mount 2 to be stably fixed to the vehicle 1000. Simultaneously, the second end face 242 can be used to secure one end of a fastener, such as by providing a bolt on one end of the fastener for installation. Furthermore, the first end face 241 can be flush with the end face of the main body 23, or it can be uneven. In some examples, the first end face 241 is flush with the end face of the main body 23, and the distance between the first end face 241 and the second end face 242 is less than the length of the main body 23.

[0059] With this design, one end of the main body 23 extends beyond the second end surface 242 , so that one end of the fastener passing through the installation channel 22 is shielded, reducing the probability of parts being exposed and making the overall structure more compact.

[0060] According to some embodiments of the present application, optionally, please refer to Figure 5 The reinforcement channel 21 partially extends to the surface of the main body 23 facing the mounting protrusion 24 , and forms a first protrusion 231 on the main body 23 .

[0061] When the reinforcement channel 21 partially extends to the surface of the main body 23 along the preset direction Z and toward the mounting protrusion 24, the surface of the main body 23 will be concave and form first protrusions 231 on both sides of the reinforcement channel 21. The first protrusions 231 can enhance the structural strength on the surface of the main body 23.

[0062] It can be known that the first protrusions 231 also extend along the extension direction X of the reinforcement channel 21. Meanwhile, when there are multiple reinforcement channels 21, there are also multiple first protrusions 231 formed.

[0063] With this design, part of the reinforcement channel 21 is extended to the surface of the main body 23 , so that the formed first protrusion 231 can enhance the structural strength on the surface of the main body 23 , thereby facilitating improvement of the overall structural mechanical strength of the first mounting component 2 .

[0064] According to some embodiments of the present application, optionally, please refer to Figure 4 The first mounting member 2 further includes a fixing protrusion 25 , which is disposed on the main body 23 facing away from the mounting protrusion 24 , and the fixing protrusion 25 and the support beam 12 are an integrated structure.

[0065] The fixing protrusion 25 and the support beam 12 are integrated, ensuring a stable connection between the first mounting member 2 and the support beam 12. The fixing protrusion 25 and the support beam 12 can be integrated by, but are not limited to, extrusion, die-casting, or 3D printing. Furthermore, the fixing protrusion 25, the main body 23, and the mounting protrusion 24 are also integrated.

[0066] Because the fixing protrusion 25 and the mounting protrusion 24 are located on opposite sides of the body portion 23 along the predetermined direction Z, when the fixing protrusion 25 is integrally formed on the support beam 12, the distance between the mounting protrusion 24 and the support beam 12 can be increased. Furthermore, the fixing protrusion 25 and the mounting protrusion 24 can also be located at opposite ends of the body portion 23 along the extension direction X of the reinforcement channel 21.

[0067] In addition, after the fixing protrusion 25 is integrally formed on the support beam 12 , the outer periphery of the fixing protrusion 25 can be welded to the support beam 12 to enhance the bonding force between the fixing protrusion 25 and the support beam 12 .

[0068] Such a design introduces a fixing protrusion 25, which facilitates the close combination of the first mounting component 2 and the support beam 12; at the same time, the fixing protrusion 25 is arranged on the side of the main body 23 facing away from the mounting protrusion 24, so that the mounting protrusion 24 can be further away from the support beam 12, thereby further improving the convenience of installation of the first mounting component 2.

[0069] According to some embodiments of the present application, optionally, please refer to Figure 4 The fixing protrusion 25 includes a third end surface 252 close to the mounting protrusion 24 , and one end of the main body 23 extends beyond the third end surface 252 along the extension direction X of the reinforcement channel 21 .

[0070] It can be seen that a stepped structure can be formed between the main body 23 and the third end face 252 , so that there is a certain space between the main body 23 and the support beam 12 , which is not only beneficial for saving materials, but also provides operating space for fixing the mounting protrusion 24 .

[0071] At the same time, the end surface of the fixing protrusion 25 away from the third end surface 252 may or may not be flush with the end surface of the main body 23. Specifically, in some examples, the end surface of the fixing protrusion 25 away from the third end surface 252 is flush with the end surface of the main body 23, and the length of the fixing protrusion 25 is less than the length of the main body 23.

[0072] Such a design is not only beneficial for saving materials, but also provides operating space for fixing the mounting protrusion 24 .

[0073] According to some embodiments of the present application, optionally, please refer to Figure 4 At least part of the reinforcement channel 21 is provided on the third end surface 252 and extends to the surface of the main body 23 facing the fixing protrusion 25 , and a second protrusion 232 is formed on the main body 23 .

[0074] When the reinforcement channel 21 partially extends to the surface of the main body 23 along the preset direction Z and toward the fixed protrusion 25, the surface of the main body 23 will be concave and form second protrusions 232 on both sides of the reinforcement channel 21. The second protrusions 232 can enhance the structural strength on the surface of the main body 23.

[0075] It can be known that the second protrusions 232 also extend along the extension direction X of the reinforcement channel 21. Meanwhile, when there are multiple reinforcement channels 21, there are also multiple second protrusions 232 formed.

[0076] With this design, part of the reinforcement channel 21 is extended to the surface of the main body 23 , so that the formed second protrusion 232 can enhance the structural strength on the surface of the main body 23 , thereby facilitating improvement of the overall structural mechanical strength of the first mounting component 2 .

[0077] According to some embodiments of the present application, optionally, please refer to Figure 4 There are multiple reinforcement channels 21 , and at least some of the reinforcement channels 21 are spaced apart around the periphery of the installation channel 22 .

[0078] A reinforcing rib 26 may be formed between two adjacent reinforcing channels 21 to enhance the structural strength of the periphery of the mounting channel 22 and improve the stability of the mounting. The number of reinforcing channels 21 may be determined based on actual needs, such as but not limited to two, three, or more.

[0079] Such a design enhances the structural strength of the periphery of the installation channel 22, which is beneficial to improving the stability of mounting.

[0080] According to some embodiments of the present application, optionally, please refer to Figure 3 The battery device further includes a second mounting member 4 . A fixing hole 41 is provided at at least one end of the frame 1 along the length direction Y of the support beam 12 , and the second mounting member 4 is passed through the fixing hole 41 .

[0081] As can be seen, the second mounting member 4 is mounted on at least one side of the frame 1 along the longitudinal direction Y through the fixing hole 41, meaning it is not integral with the frame 1. When the battery device 100 is installed and secured, the frame 1 is stably mounted using the first mounting member 2 and the second mounting member 4, respectively. The second mounting member 4 can have a variety of shapes, such as, but not limited to, a sleeve.

[0082] To facilitate installation of the second mounting member 4 on the frame 1, the frame 1 is provided with a protruding beam 16 on at least one side along the length direction Y of the support beam 12, and a fixing hole 41 is provided on the protruding beam 16. In some examples, one end surface of the protruding beam 16 along the extension direction X of the support beam 12 can be lower than another end surface of the support beam 12 along the extension direction X. In this way, one end of the second mounting member 4 fixed to the protruding beam 16 can also be lower than another end surface of the support beam 12 along the extension direction X.

[0083] The number of second mounting members 4 can be one or more. When there are multiple second mounting members 4, they can be respectively disposed at opposite ends of the frame 1 along the length direction Y of the support beam 12. Furthermore, the number of second mounting members 4 can also be multiple at either end of the frame 1 along the length direction Y of the support beam 12, and the second mounting members 4 can be spaced apart along a predetermined direction Z.

[0084] With such a design, the introduction of the second mounting member 4 can increase the mounting points of the battery device 100 at different positions, which is beneficial to improving the installation stability of the battery device 100 .

[0085] According to some embodiments of the present application, optionally, please refer to Figure 3 , the first mounting component 2 extends beyond one end surface of the support beam 12 along the extension direction X of the reinforcement channel 21 .

[0086] As can be seen, this allows the first mounting member 2 to more easily contact the intended installation location, such as the body of the vehicle 1000, facilitating secure installation of the battery device 100. Specifically, in some examples, the first mounting member 2 includes a main body 23 and a mounting protrusion 24 protruding from the main body 23 along a predetermined direction Z. One end of the mounting protrusion 24 extends beyond one end surface of the support beam 12 along the extension direction X.

[0087] Such a design makes it easier for the first mounting member 2 to contact the location to be installed, thereby facilitating the fixed installation of the battery device 100 .

[0088] According to some embodiments of the present application, optionally, please refer to Figure 3 The frame 1 includes two longitudinal beams 13, two transverse beams 14 and two oblique beams 15. The two longitudinal beams 13 are arranged side by side and spaced apart. One transverse beam 14 is connected between the ends of the two longitudinal beams 13 on one side, and both ends of the other transverse beam 14 are connected between the ends of the two longitudinal beams 13 on the other side through oblique beams 15 to enclose and form an accommodating space 11. At least one of each longitudinal beam 13, each transverse beam 14 and each oblique beam 15 is a support beam 12.

[0089] It can be seen that at least one of the longitudinal beam 13 , the transverse beam 14 and the oblique beam 15 can be the support beam 12 , which means that the first mounting component 2 can be integrally formed with any one of the longitudinal beam 13 , the transverse beam 14 and the oblique beam 15 .

[0090] Specifically in some examples, the first mounting component 2 is arranged on the surface of at least one cross beam 14 facing away from the accommodating space 11, and a convex beam 16 is protruded from the surface of each longitudinal beam 13 facing away from the accommodating space 11, a fixing hole 41 is provided on the convex beam 16, and the second mounting component 4 is passed through the fixing hole 41.

[0091] Such a design facilitates the arrangement of the first mounting member 2 on the frame 1 and improves the stability of the mounting.

[0092] According to some embodiments of the present application, the present application provides an electric device, which includes the battery device 100 according to any one of the above items.

[0093] According to some embodiments of this application, please refer to Figures 3 to 5 The present application provides a battery device 100, which includes a frame 1, a battery cell 10, and a first mounting member 2. The frame 1 defines a storage space 11, in which the battery cell 10 is accommodated. The frame 1 includes a support beam 12 located on one side of the battery cell 10 along a predetermined direction Z. The first mounting member 2 is integrally formed by extrusion on a surface of the support beam 12 facing away from the storage space 11. A reinforcement channel 21 and a mounting channel 22 are formed through the first mounting member 2. The extension direction X of the reinforcement channel 21, the predetermined direction Z, and the length direction Y of the support beam 12 are mutually perpendicular.
