Description

[Technical Field]

[0001] [CROSS-REFERENCE TO RELATED APPLICATIONS] This application claims priority to a Chinese patent application filed on June 9, 2023, bearing application number 2023106824038 and entitled "Battery Mounting Device, Battery and Power Consumption Device," all of which are incorporated herein by reference.

[0002] This application is in the field of batteries, and specifically relates to battery mounting devices, batteries, and power consuming devices. [Background technology]

[0003] Some power-consuming devices, especially electric or hybrid vehicles, require a large number of batteries to power the vehicle. When a vehicle requires a relatively large number of batteries, the optimal location for the batteries is to mount them on the vehicle mounting cross member. Therefore, a mounting device is required to mount the batteries on the vehicle mounting cross member.

[0004] However, in some cases, a mid-mounting device is commonly used to mount the battery on the cross member, but the mid-mounting device needs to penetrate the battery, occupying the internal space of the battery and reducing space utilization. Summary of the Invention

[0005] The present application provides a battery mounting device, a battery, and a power consumption device that can solve the problem that the central mounting device needs to penetrate the battery, occupying the internal space of the battery and reducing space utilization.

[0006] To solve the above technical problems, the present application adopts the following technical solution: A mounting device is provided, the mounting device including: a mounting member having a protrusion, a portion of the mounting member being flat, the flat portion being connected to a battery housing, the protrusion and the flat portion being located on opposite sides of the mounting member; and an assembly member connected to the protrusion of the mounting member.

[0007] The battery is fixed on the external component by connecting it to the mounting component and then connecting it to the external component via the assembly component, and the mounting component is connected to the battery housing via the flat portion, i.e., the connection between the mounting component and the battery housing is achieved by a surface connection method, which does not require penetrating the battery or occupying the internal space of the battery, thereby improving the space utilization rate of the battery.

[0008] In some embodiments, the mounting member defines a receiving space at the location of the protrusion, and at least a portion of the assembly member is located within the receiving space.

[0009] By installing the assembly member in the receiving space, the assembly member and the mounting member can be fixed together, and the fixing effect is good.

[0010] In some embodiments, a first opening is formed on the protrusion, and a portion of the assembly member is placed through the first opening to connect with an external member.

[0011] Since a portion of the assembly member is located in the accommodation space and a portion passes through the first opening, the assembly member is fixed relatively firmly, making the connection between the assembly member and the external member more stable.

[0012] In some embodiments, a second opening is formed in the mounting member at a location corresponding to the protrusion.

[0013] By providing the second opening, the assembly member and the mount member can be assembled relatively easily.

[0014] In some embodiments, the mounting member includes a connecting member and a support member, the protrusions being located on the support member, and the connecting members being located on at least both sides of the support member.

[0015] By forming a protrusion on the support member, it is possible to ensure that the connecting member does not have any protrusions, which makes it easier to connect with the battery and reinforces the overall strength of the mounting member.

[0016] In some embodiments, the connecting member is provided on the side of the support member away from the protrusion.

[0017] The overall strength of the mounting member can be further reinforced by providing protrusions on the support member.

[0018] In some embodiments, the mounting arrangement further includes a gasket, the gasket being disposed around the protrusion and abutting the mounting member.

[0019] Waterproofing can be achieved by installing a gasket.

[0020] In some embodiments, the thickness of the gasket is no less than the height of the protrusions.

[0021] The height of the protrusion limits the amount of compression of the gasket, controls the amount of compression of the gasket within a reasonable range, and ensures the reliability of the seal.

[0022] In some embodiments, the mounting members are elongated structures, and the projections on each mounting member are spaced apart along the length of the mounting member.

[0023] By providing multiple protrusions on each mounting member, relatively long or large batteries can be secured with a relatively small number of mounting members, thereby saving on the number of mounting members.

[0024] In some embodiments, the mounting members and the assembly members are multiple, with one protrusion provided on each mounting member and each protrusion connected to one of the assembly members.

[0025] By providing multiple mounting members, the distribution of the mounting members may be flexibly set.

[0026] The assembly member is a bolt, and the bolt includes a head and a stud connected to one side of the head, the head being installed within the accommodating space, and the stud being installed through the protrusion.

[0027] Bolts are suitable as assembly members, have a simple structure, and provide highly reliable connections.

[0028] The assembly member is a nut, the nut is installed in the receiving space, and a screw hole of the nut corresponds to the first opening.

[0029] The assembly member is set as a nut and can be fitted with an external bolt structure, which has a simple structure and strong connection reliability.

[0030] In order to solve the above technical problems, the present application adopts the following alternative technical solution: A battery is provided, the battery includes a mounting device, and the mounting device is the mounting device described in any one of the above claims.

[0031] The connection between the mounting member and the battery housing is realized by a surface connection method, which does not require penetrating the battery, does not occupy the internal space of the battery, and improves the space utilization rate of the battery.

[0032] To solve the above technical problems, the present application also adopts the following technical solution: A power consumption device is provided, the power consumption device includes any one of the batteries described above, and the battery is used to provide electrical energy.

[0033] The connection between the mounting member and the battery housing is achieved by a surface connection method, which does not require penetrating the battery or occupying the internal space of the battery, thereby improving the space utilization rate of the battery in the power consumption device.

In the description of this application, unless otherwise specified, "plurality" means two or more.

[0037] In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "center," "lateral," "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "axial," "radial," "circumferential," etc. are orientations or positional relationships shown based on the drawings, and are merely for the convenience and simplification of the description of the present application, and do not indicate or imply that the referred-to devices or elements must have a specific orientation or be configured and operated in a specific orientation, and therefore should not be understood as limitations on the present application.

[0038] In the description of this application, it should be explained that unless otherwise clearly defined or limited, the terms "attached," "connected," "joined," and "attached" should be understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, or an integral connection, a direct connection, an indirect connection via an intermediate medium, or internal communication between two elements. Those skilled in the art can understand the specific meanings of the above terms in this application according to specific circumstances.

[0039] The term "embodiment" as used herein means that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the present application. Appearances of this phrase in various places in the specification do not necessarily refer to the same embodiment, nor do they refer to an embodiment that is independent of or substitutes for other embodiments, and are exclusive of other embodiments. It is understood by those skilled in the art, both explicitly and implicitly, that the embodiment described in the present application can be combined with other embodiments.

[0040] As mentioned above, it should be emphasized that the term "comprises", when used herein, is intended to expressly state and denote the presence of said feature, integer, step or assembly, but does not exclude the presence or addition of one or more other features, integers, steps, components or sets of features, integers, steps, components. For example, when used in this application, the singular forms "one", "an" and "this" also include the plural form unless the context clearly dictates otherwise.

[0041] As used herein, the terms "one" and "an" can mean one, but can also mean "at least one" or "one or more." The term "about" generally refers to a stated numerical value plus or minus 10%, or more specifically, plus or minus 5%. The term "or" used in the claims means "and / or" unless it is clearly indicated to refer only to alternatives.

[0042] The term "and / or" in this application merely describes the relationship between related objects and indicates that three relationships may exist, for example, A and / or B may represent three cases: A alone, a combination of A and B, and B alone. Also, the character " / " in this application generally indicates that the related objects before and after are in an "or" relationship.

[0043] The battery referred to in the embodiments disclosed herein refers to a single physical module containing one or more battery cells to provide a predetermined voltage and capacity. For example, the battery referred to in the present application may include a battery module or a battery pack. The battery cell is the basic unit of a battery and can generally be divided into cylindrical battery cells, rectangular battery cells, and pouch battery cells depending on the packaging method. The following description will mainly focus on rectangular battery cells. It should be understood that the embodiments described below can also be applied to cylindrical battery cells or pouch battery cells in some aspects.

[0044] A battery cell includes a positive electrode plate, a negative electrode plate, an electrolyte, and a separator. Lithium-ion battery cells primarily rely on the movement of lithium ions between the positive and negative electrodes to function. For example, lithium-ion battery cells use a single incorporated lithium compound as an electrode material. Currently, commonly used positive electrode materials for lithium-ion batteries are mainly lithium cobalt oxide (LiCoO), lithium manganese oxide (LiMnO), lithium nickel oxide (LiNiO), and lithium iron phosphate (LiFePO). A separator is placed between the positive and negative electrodes to form a film structure with three layers of material. This film structure is typically fabricated into an electrode assembly of a desired shape by winding or stacking. For example, in a cylindrical battery cell, the film structure of the three layers of material is wound into a cylindrical electrode assembly, while in a rectangular battery cell, the film structure is wound or stacked into an electrode assembly with a roughly rectangular parallelepiped shape.

[0045] Multiple battery cells may be connected in series and / or parallel via electrode terminals for use in various applications. In some high-power applications, such as electric vehicles, battery applications include three levels: battery cells, battery modules, and batteries. A battery module protects battery cells from external impact, heat, vibration, and the like, and is formed by electrically connecting a certain number of battery cells together and placing them within a framework. A battery is the final state of a battery system installed in an electric vehicle. A battery generally includes a housing for packaging one or more battery cells. The housing can prevent liquids or other foreign objects from affecting the charging or discharging of the battery cells. The housing generally consists of a cover and a housing case, which generally includes a bottom plate and an outer plate. The outer plate extends from the edge of the bottom plate and is generally perpendicular to the bottom plate. The bottom plate and the outer plate form a storage space with an opening, which is used to store battery cells or battery modules. The cover closes the opening of the storage space, faces the bottom plate, and is connected to the outer plate. The housing case and the cover may be detachably connected or sealed. Most current batteries are manufactured by assembling various control and protection systems, such as a battery management system (BMS) and thermal management components, onto one or more battery modules. With the development of technology, the term "battery module" may be omitted, i.e., a battery is formed directly from battery cells. When multiple battery cells are connected together, it is called a battery module. This improvement increases the gravimetric energy density and volumetric energy density of the battery system while significantly reducing the number of parts. The battery referred to in this application includes a battery module or a battery.

[0046] A pressure relief mechanism is generally installed on a battery cell. The pressure relief mechanism is an element or component that can be activated to release internal pressure when the internal pressure or temperature of the battery cell reaches a predetermined threshold. The pressure relief mechanism is also called an explosion-proof valve, an air valve, a pressure relief valve, or a safety valve. The pressure relief mechanism can specifically employ a pressure- or temperature-sensitive element or structure. That is, when the internal pressure or temperature of the battery cell reaches a predetermined threshold, the pressure relief mechanism activates, or a fragile structure provided in the pressure relief mechanism breaks, thereby forming an opening or channel for releasing internal pressure.

[0047] In some cases, the middle mount device includes a middle mount sleeve, a middle mount adapter sleeve, a sealing ring, and a nut. Here, the middle mount sleeve fits into the middle mount adapter sleeve and penetrates the battery. The sealing ring is installed between the middle mount sleeve and the middle mount adapter sleeve to achieve a seal between the middle mount sleeve and the middle mount adapter sleeve. When connecting the middle mount device to the battery, the middle mount device must avoid the battery modules in the battery, and its position cannot be arbitrarily positioned. Furthermore, because the middle mount device must penetrate the battery, it occupies internal space of the battery. Therefore, the penetration portion of the middle mount device must be reserved in advance when manufacturing the battery, reducing the space utilization rate within the battery.

[0048] To solve the problem of the middle mounting device needing to penetrate the battery, occupying the battery's internal space and reducing space utilization, it should be noted that the main cause is the need for the middle mounting device to penetrate the battery. Therefore, by improving the middle mounting device, the middle mounting device can be connected to the battery using a flat connection method, such as welding or pasting. Therefore, the middle mounting device can be divided into an interconnected mounting member and an assembly member, where the mounting member is connected to the battery via a first surface, and the assembly member is connected to an external member that needs to fix the battery, thereby eliminating the need to penetrate the battery, not occupying the battery's internal space, and improving the battery's space utilization.

[0049] Based on the above considerations, a battery mounting device, a battery, and a power consumption device were designed to solve the problem that the middle mounting device needs to penetrate the battery, occupying the internal space of the battery and reducing the space utilization rate.

[0050] For example, as shown in FIG. 1 , this figure is a simplified schematic diagram of a vehicle 1, an electric power consumption device according to some embodiments. The vehicle 1 may be a fuel oil vehicle, a gas vehicle, or a new energy vehicle. The new energy vehicle may be a pure electric vehicle, a hybrid vehicle, or a range-extended electric vehicle, etc. A battery 10 may be installed inside the vehicle 1, for example, at the bottom, front, or rear of the vehicle 1. The battery 10 may be used to power the vehicle 1, for example, as an operating power source for the vehicle 1. The vehicle 1 may further include a controller 30 and a motor 40. The controller 30 is used to control the battery 10 to power the motor 40, for example, to meet the operating power consumption needs of the vehicle 1 during startup, navigation, and driving. In another embodiment of the present application, the battery 10 may provide not only the operating power source for the vehicle 1 but also the driving power source for the vehicle 1, providing driving power instead of, or part of, fuel oil or natural gas. Hereinafter, the battery 10 may be understood as a battery including a plurality of battery cells 20.

[0051] FIGS. 2 and 3 each show exploded views of a battery 10 according to some embodiments. As shown in FIGS. 2 and 3, the battery 10 includes a plurality of battery cells 20 and busbar members 12 for electrically connecting the plurality of battery cells 20. To protect the battery cells 20 from intrusion or corrosion by external liquids or foreign objects, the battery 10 includes a housing 11, which is used to package the plurality of battery cells and other necessary components, as shown in FIGS. 2 and 3. In some embodiments, the housing 11 may include a cover 111 and a housing case 112. The battery 10 may further include a support beam 114 extending between the cover 111 and the housing case 112. The support beam 114 may extend from a bottom plate 112a of the housing case 112 to the cover 111 in a direction perpendicular to the bottom plate 112a. The cover 111 and the housing case 112 are sealed together to form an electrical cavity 11a for accommodating the plurality of battery cells 20. In some other embodiments, the lid 111 and the housing case 112 may be fitted together without being sealed.

[0052] As shown in FIGS. 4 to 8 , FIG. 4 is a structural schematic diagram of a mounting device according to some embodiments, FIG. 5 is a cross-sectional view of a mounting device according to some embodiments, FIG. 6 is an exploded structural schematic diagram of a battery according to some embodiments, FIG. 7 is a planar structural schematic diagram of the battery in FIG. 6, and FIG. 8 is a cross-sectional structural schematic diagram taken along line AA in FIG. 7. In some embodiments, the mounting device for battery 10 includes a mounting member 51 and an assembly member 52. A protrusion 53 is formed on mounting member 51, and a portion of mounting member 51 is flat, which is connected to the housing 11 of battery 10. Protrusion 53 and this flat surface are located on opposing sides of mounting member 51. Assembly member 52 is connected to protrusion 53 of mounting member 51 and is used to connect an external component.

[0053] The mounting member 51 may be a folded plate-like or sheet-like structure, such as a square-shaped or square-shaped structure, and is used to connect the battery 10 and the assembly member 52. One surface of the mounting member 51 is flat, and this flat surface is used to connect with the housing 11 of the battery 10. As shown in FIG. 5 , the lowermost surface of the mounting member 51 is flat, and is used to connect with the housing 11 of the battery 10. The mounting member and the housing 11 may be connected by adhesive, welding, or engagement. In some embodiments, the mounting member 51 is connected to the cover 111 of the housing 11. The protrusion 53 is one or more protrusions formed on the mounting member 51. In some embodiments, the protrusion protrudes in a direction perpendicular to the surface of the connection between the housing 11 and the mounting device, and in a direction away from the housing 11. Because the protrusion 53 is intended to connect the assembly member 52, it must avoid the housing 11 and must not protrude toward the housing 11. As shown in FIG. 5 , the lower portion of the mounting member 51 in the drawing is a plane used for connecting the housing 11, and the protrusion 53 protrudes upward along the mounting member 51 in the drawing. The lower portion in the drawing corresponds to the direction x, and the upper portion in the drawing corresponds to the opposite direction of the direction x. Therefore, the plane is located on the underside of the mounting member 51, and the protrusion 53 is located on the upper side of the mounting member 51; that is, the protrusion 53 and the plane are located on opposite sides of the mounting member 51. The assembly member 52 is a device for connecting an external component to the mounting device. Depending on the connection method with the external component, the assembly member 52 may be a different component. The connection method between the assembly member 52 and the protrusion 53 may be abutting connection, welding, adhesive bonding, etc., or the assembly member 52 may be clamped and fixed by cooperation between the protrusion 53 of the mounting member 51 and the housing 11.

[0054] Battery 10 is fixed to the external component by connecting it to the battery 10 housing via mounting member 51 and then connecting it to the external component via assembly member 52. Mounting member 51 is connected to the battery 10 housing 11 via a flat portion, i.e., a surface-to-surface connection is used to achieve the connection between mounting member 51 and battery 10 housing 11. This eliminates the need to penetrate battery 10 and does not occupy the internal space of battery 10, improving the space utilization rate of battery 10.

[0055] As shown in Fig. 9, Fig. 9 is a structural schematic diagram of a mounting device according to some other embodiments. In some embodiments, the mounting member 51 forms a receiving space at the position of the protrusion 53. At least a portion of the assembly member 52 is located within the receiving space.

[0056] The storage space is a space for storing at least some of the assembly members 52. This storage space may be formed solely by the mounting member 51, or may be formed by a combination of the protrusions 53 of the mounting member 51 and the battery 10. When at least some of the assembly members 52 are positioned within the storage space, they can be overlapped in height with the protrusions 53, thereby saving space in the height direction.

[0057] By installing the assembly member 52 in the receiving space, the assembly member 52 and the mounting member 51 can be fixed together, which saves space in the height direction and provides a good fixing effect.

[0058] 9, which is a structural schematic diagram of a mounting device according to some other embodiments. In some embodiments, a first opening 531 is formed on the protrusion 53, and a part of the assembly member 52 is installed through the first opening 531 to be connected to an external member.

[0059] The first opening 531 is an opening in the protrusion 53. When only a portion of the assembly member 52 is positioned within the accommodation space, the portion of the assembly member 52 that is not installed within the accommodation space is exposed through the first opening 531. When the entire assembly member 52 is positioned within the accommodation space, the external member is connected to the assembly member 52 in the accommodation space through the first opening 531. A portion of the assembly member 52 may pass through the first opening 531, thereby connecting with the external member and cooperating with the external member to fix it. In some embodiments, the cross-sectional area of ​​the portion of the assembly member 52 positioned within the accommodation space at the first opening 531 is larger than the cross-sectional area of ​​the first opening 531, and therefore the portion cannot be stably fixed within the accommodation space through the first opening 531.

[0060] A part of the assembly member 52 is located in the accommodation space, and a part of it passes through the first opening 531, but the part of the assembly member 52 located within the accommodation space is limited within the accommodation space and cannot pass through the first opening, so that the assembly member 52 is fixed relatively firmly and the connection between the assembly member 52 and the external member can be made more stable.

[0061] Referring again to FIG. 5, in some embodiments, a second opening 513 is formed in the mounting member 51 at a position corresponding to the protrusion 53 .

[0062] The second opening 513 corresponds to the first opening 531, and the second opening 513 should be located at the bottom of the protrusion 53. In some embodiments, because the surface of the protrusion 53 is arc-shaped, the cross-sectional area of ​​the first opening 531 is larger than the cross-sectional area of ​​the second opening 513. By providing the second opening 513, the assembly member 52 can be placed in the receiving space through the second opening 513.

[0063] By providing the second opening 513, the assembly member 52 and the mounting member 51 can be assembled relatively easily.

[0064] In some embodiments, the mount member 51 includes a connecting member 511 and a support member 512, the protrusions 53 are located on the support member 512, and the connecting members 511 are installed on at least both sides of the support member 512. Referring to Figure 5, the plane of the mount member 51 is installed on the connecting member 511 and is located on a surface of the connecting member 511 that faces in the direction x.

[0065] The connecting member 511 is a member for connecting to the battery 10, and the supporting member 512 is a member for supporting the connecting member 511. The connecting member 511 may be installed on both sides of the supporting member 512, or may be installed around the periphery of the supporting member 512. The connecting member 511 and the supporting member 512 may have an integrally molded structure. The portions of the connecting member 511 and the supporting member 512 on which the protrusions 53 are not installed may be located on the same plane.

[0066] By forming the protrusions 53 on the support member 512, it is possible to ensure that the connecting member 511 does not have any protrusions, which facilitates connection with the battery 10 and reinforces the overall strength of the mounting member 51.

[0067] In some embodiments, the connecting member 511 is provided on the side of the support member 512 away from the protrusion 53 .

[0068] The connecting member 511 is connected to the housing 11 of the battery 10, and the support member 512 is installed to protrude from the connecting member 511, i.e., there is a gap between the support member 512 and the housing 11. When installed in this manner, a height difference is formed between the support member 512 and the connecting member 511, allowing the support member 512 to function as a reinforcing rib. The support member 512 may be formed by press-molding the connecting member 511 in a direction away from the housing 11. An edge of the support member 512 is connected to the connecting member 511, and a portion of the support member 512 where the protrusion 53 is not installed may be installed parallel to the connecting member 511.

[0069] The protrusions on the support member 512 can further reinforce the overall strength of the mount member 51.

[0070] In some embodiments, the mounting device for battery 10 further includes a gasket 54 , which is disposed around protrusion 53 and which abuts mounting member 51 .

[0071] The gasket 54 is made of a waterproof material to prevent liquid penetration. In some embodiments, the gasket 54 is made of a resilient material. The thickness of the gasket 54 after the mounting device is attached may be equal to or less than the thickness of the gasket 54 without the mounting device attached.

[0072] The installation of the gasket 54 can provide a waterproof function.

[0073] In some embodiments, the thickness of the gasket 54 is no less than the height of the protrusions 53 .

[0074] The height of the protrusion 53 limits the amount of compression of the gasket 54, and controls the amount of compression of the gasket 54 within a reasonable range to ensure the reliability of the seal.

[0075] In some embodiments, the mounting members 51 are elongated structures, and the protrusions 53 on each mounting member 51 are spaced apart along the length of the mounting member 51 .

[0076] Since the battery 10 generally has a rectangular parallelepiped structure and its lid 111 generally has a rectangular structure, the mounting member 51 is installed in an elongated structure to match the shape of the battery 10. The width of the mounting member 51 is smaller than the width of the battery 10 or its lid 111. Adjacent protrusions 53 may be installed at equal intervals. One battery 10 may be fixed via multiple mounting members 51.

[0077] By providing a plurality of protrusions 53 on each mounting member 51, a relatively long or relatively large battery 10 can be fixed with a relatively small number of mounting members 51, thereby reducing the number of mounting members 51 required.

[0078] 11, which is a structural schematic diagram of a mounting device according to some further embodiments. In some embodiments, there are a plurality of mounting members 51 and assembly members 52, and one protrusion 53 is provided on each mounting member 51, and each protrusion 53 is connected to one assembly member 52.

[0079] When one protrusion 53 is provided on each mounting member 51, the shape of the mounting members 51 may be arbitrarily set, such as circular, oval, square, rectangular, triangular, other polygonal, or other regular or irregular shape as required. With such a configuration, the mounting members 51 can be laid out as required, and one battery 10 is fixed via multiple mounting members 51 and assembly members 52, and the connection positions between the mounting members 51 and the batteries 10 can be adjusted according to actual needs.

[0080] By providing multiple mounting members 51, the weight of the batteries 10 can be distributed, and the stability of the connection of the mounting members 51 can be improved.

[0081] In some embodiments, the assembly member 52 is a bolt, which includes a head and a stud connected to one side of the head, the head being installed within the receiving space and the stud being installed through the protrusion 53.

[0082] A bolt is a commonly used fastening device. A male thread is formed on a stud, and is used to mate with an external member such as a nut. Because the radial cross-sectional area of ​​the head is larger than the radial cross-sectional area of ​​the stud, the head can be placed within the receiving space, and the stud can pass through the first opening 531 and extend away from the battery 10.

[0083] Bolts are suitable as the assembly members 52, and have a simple structure and high connection reliability.

[0084] The assembly member 52 is a nut, which is installed in the receiving space, and the screw hole of the nut corresponds to the first opening 531 .

[0085] The screw hole of the nut is a hole in which an internal thread is formed in the nut, and may be a through hole or a blind hole. The cross-sectional area of ​​the first opening 531 must not be smaller than the cross-sectional area of ​​the screw hole in the radial direction. The center of the first opening 531 is preferably on the axis of the screw hole.

[0086] The assembly member 52 is configured as a nut and can be fitted with an external bolt structure, which has a simple structure and strong connection reliability.

[0087] In some embodiments, the battery includes a housing and a mounting device, the mounting device being connected to the housing, the mounting device being any one of the above mounting devices.

[0088] The connection between the mounting member 51 and the housing 11 of the battery 10 is achieved by a surface connection method, which does not require penetrating the battery 10 and does not occupy the internal space of the battery 10, thereby improving the space utilization rate of the battery 10.

[0089] In some embodiments, a power consuming device includes a battery 10 as described above, the battery 10 being used to provide electrical energy.

[0090] The connection between the mounting member 51 and the housing 11 of the battery 10 is achieved using a surface connection method, which does not require penetrating the battery 10 and does not occupy the internal space of the battery 10, thereby improving the space utilization rate of the battery 10 in the power consumption device.

[0091] In some specific application scenarios, the intermediate mounting device needs to penetrate the battery 10, occupying the battery 10's internal space and reducing space utilization. To address this issue, the intermediate mounting device of the present application includes a mounting member 51, an assembly member 52, and a gasket 54. A protrusion 53 is formed on the mounting member 51, and a portion of the mounting member 51 is flat, which connects to the battery 10's housing 11. The protrusion 53 and the flat surface are located on opposite sides of the mounting member 51. The assembly member 52 is connected to the protrusion 53 of the mounting member 51 and is used to connect an external component. The mounting member 51 forms an accommodating space at the position of the protrusion 53, and a first opening 531 is formed on the protrusion 53. The assembly member 52 is a bolt, which includes a head and a stud connected to one side of the head. The head is installed in the accommodating space, and the stud is installed through the first opening 531 of the protrusion 53. A second opening is formed on the first surface at a position corresponding to the protrusion 53. Mount member 51 includes connecting member 511 and support member 512. Protrusions 53 are located on support member 512, and connecting member 511 is installed on at least both sides of support member 512. Support member 512 is installed to protrude from connecting member 511, and the protrusion direction is the same as the protrusion direction of protrusions 53. Gasket 54 is installed corresponding to protrusions 53 and is located on a second surface of mount member 51 that is away from the first surface.

[0092] The battery 10 is fixed to the external component by connecting it to the casing 11 of the battery 10 via the mounting member 51 and then connecting it to the external component via the assembly member 52. The mounting member 51 is connected to the battery 10 via a flat surface, i.e., a surface-to-surface connection is used to achieve the connection between the mounting member 51 and the casing 11 of the battery 10. This eliminates the need to penetrate the battery 10 and does not occupy the internal space of the battery 10, improving the space utilization rate of the battery 10.

[0093] The above is merely an embodiment of the present application and is not intended to limit the patent scope of the present application. Any equivalent structure or equivalent flow conversion made by utilizing the contents of the specification and drawings of the present application, or used directly or indirectly in other related technical fields, is also included in the patent protection scope of the present application.
