Description

CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] This application is incorporated by reference into Chinese Patent Application No. 202311163622.1, entitled "Housing, Battery and Power Consumption Device," filed on September 8, 2023, the entire contents of which are incorporated by reference into this application. [Technical Field]

[0002] The present application relates to the field of battery structure technology, and in particular to a housing, a battery, and a power consuming device. [Background technology]

[0003] When the battery is installed and used, it is connected to the main body of the power consuming device via a beam structure installed in the battery housing, thereby realizing the battery being installed and fixed to the main body of the power consuming device such as a vehicle, airplane, ship, etc. However, during operation, the power consuming device may vibrate, which may cause the battery to vibrate with a certain amplitude relative to the main body, resulting in a relatively large stress between the beam structure of the housing and the bottom plate of the housing, and a relatively high risk of breakage occurring between the beam structure and the bottom plate.

[0004] The purpose of the embodiments of the present application is to provide a housing, a battery, and a power-consuming device, and to solve the problem that in related technologies, when the housing is mounted and used, relatively large stress may occur between the beam structure and the bottom plate, making it easy for breakage to occur between the beam structure and the bottom plate.

[0005] To achieve the above objectives, the technical solutions adopted in the embodiments of this application are as follows:

[0006] According to a first aspect, an embodiment of the present application provides a housing, the housing being used to be installed on a main body of a power consuming device, the housing including a bottom plate and a mounting beam, the bottom plate having an outer wall surface, the mounting beam being used to connect the main body, the mounting beam including a connecting portion, the connecting portion being configured to be connected to the bottom plate, and at least a portion of the connecting portion being attached to the outer wall surface.

[0007] Beneficial effects of the embodiments of the present application: The housing according to the embodiments of the present application may be connected to the main body of the power-consuming device by mounting beams, wherein the mounting beams are connected and attached to the bottom plate through connecting parts, and the mounting beams can improve the contact area between the bottom plate by installing the connecting parts, so that the larger contact area between the bottom plate and the connecting parts can distribute stress between the bottom plate and the mounting beams, i.e., there is a lower risk of breakage occurring between the bottom plate and the connecting parts, and the housing is more secure when mounted on the main body of the power-consuming device through the mounting beams and used.

[0008] In some embodiments, the mounting beam further comprises a beam body for connecting to the body, the connection portion being mounted to the beam body.

[0009] By adopting the above technical solution, when the mounting beam is used to mount the housing on the main body, the beam body of the mounting beam can be connected to the main body, and the connection part of the mounting beam is installed on the beam body and connected to the outer wall surface of the bottom plate and bonded together to achieve stress distribution and reduce the probability of breakage occurring between the mounting beam and the bottom plate when the housing is mounted on the main body.

[0010] In some embodiments, the connector extends outside and beyond the beam body.

[0011] By adopting the above technical solution, the connection part can be extended beyond the beam body, i.e., the connection part has a larger bonding area with the outer wall surface of the bottom plate, and the effect of distributing the force acting on the bottom plate at the connection part is better, so that the risk of breakage occurring between the mounting beam and the bottom plate is lower, and the housing is mounted more stably on the body.

[0012] In some embodiments, the beam body is spaced apart from the exterior wall surface.

[0013] By adopting the above technical proposal, when the connection portion of the mounting beam is connected to the bottom plate and attached to the outer wall surface of the bottom plate, a gap is formed between the beam body of the mounting beam and the outer wall surface of the bottom plate, thereby allowing the beam body to act as a relief against the outer wall surface of the bottom plate, and reducing the risk of interference between the beam body and the structure installed on the outer wall surface of the bottom plate.

[0014] In some embodiments, an attachment structure is provided on the beam body, and the beam body is configured to be connected to the body via the attachment structure, and along the thickness direction of the bottom plate, the projection of the attachment structure is located within the projection of the connection portion.

[0015] By adopting the above technical solution, when the beam body of the mounting beam is connected to the main body via the mounting structure, the main body may vibrate, causing the housing to vibrate relative to the main body, and as a result, the entire weight of the housing will create a relatively large acting force between the mounting structure and the main body, and at the same time, a certain amplitude of vibration will be created between the connection part of the mounting beam and the bottom plate, generating a relatively large acting force. By installing the mounting structure so that the projection of the bottom plate in the thickness direction is located inside the connection part, the acting force between the main body and the mounting structure will approximately overlap with the position of the acting force between the connection part and the bottom plate in the thickness direction of the bottom plate, thereby effectively reducing the acting force between the main body and the mounting structure and the acting force between the connection part and the bottom plate from forming a lever effect on the mounting beam, and reducing the damage between the mounting beam and the main body connected to the mounting beam and the bottom plate. The risk of breakage between the mounting beam and the bottom plate is lower, and the housing is more stably mounted on the main body.

[0016] In some embodiments, the beam body abuts the exterior wall surface.

[0017] By adopting the above technical solution, the connection part of the mounting beam can be connected to the outer wall surface of the bottom plate and at least partially bonded to it, and the beam body can further abut the outer wall surface, thereby effectively increasing the contact area between the mounting beam and the bottom plate; that is, the mounting beam can simultaneously distribute the acting force with the bottom plate through the beam body and the connection part, further reducing the risk of breakage occurring between the mounting beam and the bottom plate.

[0018] In some embodiments, the entire connection is configured to be symmetrically positioned about the central axis of the beam body.

[0019] By adopting the above technical solution, the process of the force acting between the main beam body of the main body being transmitted between the connection part and the bottom plate becomes more uniform, so that the effect of dispersing the force acting on the bottom plate at the connection part is better, and the risk of breakage occurring between the mounting beam and the bottom plate is lower.

[0020] In some embodiments, the base plate has a beam body disposed along its central axis.

[0021] By adopting the above technical solution, when the main body vibrates, the housing also vibrates relative to the main body, and the mounting beam is connected to the main body, which can be equivalent to other parts of the housing vibrating relative to the mounting beam. The beam body of the mounting beam is arranged on the central axis of the bottom plate, i.e., the mounting beam is located at the center of the amplitude of the bottom plate, and the connection part of the mounting beam receives the acting force of the bottom plate more uniformly, which can also to some extent mitigate the risk of the mounting beam breaking.

[0022] In some embodiments, the number of connections is multiple and the multiple connections are spaced apart.

[0023] By adopting the above technical solution, the bottom plate can be connected and attached using multiple connecting parts installed at intervals, and the multiple connecting parts can distribute the acting force of the bottom plate, effectively reducing the risk of breakage occurring between the connecting parts and the bottom plate.

[0024] In some embodiments, the mounting beam further includes a beam body, wherein a portion of the beam body facing the outer wall surface forms a connection portion, and a portion of the beam body facing away from the outer wall surface forms a mounting portion, the mounting portion being used to connect the body, and along the thickness direction of the bottom plate, a projection of the mounting portion is located within the projection of the connection portion.

[0025] By adopting the above technical solution, the projection of the mounting part is set so as to be located within the projection of the connection part in the thickness direction of the bottom plate, i.e., the area of ​​the connection part is larger than the area of ​​the mounting part, and the connection and bonding with the bottom plate are realized using the connection part with a larger area, which can distribute the acting force on the connection part of the bottom plate, thereby effectively reducing the risk of breakage occurring between the connection part and the bottom plate.

[0026] In some embodiments, a channel is provided in the base plate, a heat exchange medium is contained in the channel, and a projection of the channel and a projection of the connection portion are separated from each other along the thickness direction of the base plate.

[0027] By adopting the above technical solution, the flow path and the connection part can be spaced apart in the thickness direction of the bottom plate, thereby reducing the influence of the connection part on the flow path.

[0028] According to a second aspect, an embodiment of the present application further provides a battery including a battery cell and a housing as described above, wherein the battery cell is located within the housing.

[0029] Beneficial effects of the embodiments of the present application: The battery according to the embodiments of the present application includes the above-mentioned housing, and the overall structure of the battery is more stable when the risk of fracture occurring between the mounting beam and the bottom plate of the housing is relatively low.

[0030] According to a third aspect, an embodiment of the present application further provides a power consumption device, comprising a main body and a battery as described above, wherein the battery housing is installed in the main body, and the battery is used to provide electrical energy.

[0031] Beneficial effects of the embodiments of the present application: The power consumption device according to the embodiments of the present application includes the above-mentioned battery, and when the overall structure of the battery is more stable, the process of the battery being installed in the main body and providing electrical energy to the main body is more stable, and the risk of the battery falling off from the main body is relatively low.

[0033] The following describes in detail the embodiments of the present application, and examples of the embodiments are shown in the drawings, in which the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the drawings are illustrative and are used to interpret the present application, and should not be understood as limitations on the present application.

[0034] In describing the present application, it should be understood that the orientations or positional relationships indicated by the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," 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.

[0035] It should be noted that the terms "first" and "second" are merely descriptive and should not be understood as indicating or implying the relative importance or the number of the technical features indicated. A feature qualified by "first" or "second" may thereby explicitly or implicitly include one or more of said features. In the description of this application, unless otherwise expressly and specifically limited, "plurality" means two or more.

[0036] In this application, unless otherwise clearly defined or limited, the terms "attached," "connected," "coupled," "fixed," etc. should be understood in a broad sense, and may refer to, for example, a fixed connection, a detachable connection, or an integral connection, a mechanical connection, an electrical connection, a direct connection, an indirect connection via an intermediate medium, an internal communication between two elements, or an interactive relationship between two elements. Those skilled in the art can understand the specific meanings of the above terms in this application according to specific circumstances.

[0037] Currently, in view of the development of the market situation, the application of power batteries is becoming more and more widespread. Power batteries are not only used in energy storage power systems such as hydroelectric, thermal, wind and solar power plants, but also widely used in electric transportation tools such as electric bicycles, electric motorcycles and electric cars, as well as military equipment and aerospace. With the continuous expansion of the application fields of power batteries, the market demand for them is also continuously increasing.

[0038] When a battery is installed and used, it is connected to the main body of the power consuming device via a beam structure installed on the battery housing, thereby mounting and securing the battery to the main body of the power consuming device, such as a vehicle, airplane, or ship, and providing electrical energy to the main body. However, vibrations may occur in the power consuming device during operation, such as when a vehicle is shaking while driving. This causes vibrations of a certain amplitude between the connected main body and the battery, i.e., stress is generated between the main body and the beam structure installed on the battery housing. Because a connection is formed between the beam structure and the bottom plate of the housing, vibrations of a certain amplitude are also generated between the beam structure and the bottom plate, and relatively large stress is generated. Because the structural strength of the beam structure is relatively high, the beam structure can withstand the stress generated between the main body, making the beam structure less likely to break. The stress generated between the beam structure and the bottom plate is likely to cause damage such as breakage between the beam structure and the bottom plate, or deformation or cracking of the bottom plate.

[0039] Based on the above considerations, in the related art, in the process of installing and using the housing, a relatively large stress may occur between the beam structure and the bottom plate, and in order to solve the problem that breakage is likely to occur between the beam structure and the bottom plate, the housing is designed to connect to the bottom plate using the connection part of the mounting beam, and at least a part of the connection part is attached to the outer wall surface of the bottom plate, and the connection part is used to increase the contact area with the bottom plate, thereby realizing stress distribution between the mounting beam and the bottom plate, and effectively reducing the probability of risks such as breakage, damage, and deformation occurring between the mounting beam and the bottom plate.

[0040] In such a housing, the housing is connected to the bottom plate using a connecting part, and the connecting part is attached to the outer wall surface of the bottom plate. When the body of the power consumption device vibrates during installation and use, the bottom plate will vibrate with a certain amplitude against the mounting beam, thereby generating stress between the bottom plate and the mounting beam. The connection method in which the connecting part is attached to the outer wall surface of the bottom plate can distribute the stress between the bottom plate and the mounting beam, thereby reducing the effect of stress concentration and reducing the risk of damage such as deformation, breakage, and crushing between the mounting beam and the bottom plate due to stress concentration. This can make the structure of the housing more stable during use and further improve the service life of the housing.

[0041] The housings disclosed in the embodiments of the present application can be used in power-consuming devices that use batteries as a power source or various energy storage systems that use batteries as an energy storage element. The power-consuming devices may be used in, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, battery-powered vehicles, electric vehicles, ships, spacecraft, etc. Here, the electric toys may include stationary or mobile electric toys, such as game consoles, electric car toys, electric steamship toys, and electric airplane toys, and the spacecraft may include airplanes, rockets, spacecraft, and spaceships.

[0042] In the following embodiment, for ease of explanation, an example will be described in which one power consuming device in one embodiment of the present application is a vehicle 1000.

[0043] Referring to FIG. 1, FIG. 1 is a structural schematic diagram of a vehicle 1000 according to some embodiments of the present application. The vehicle 1000 may be a gasoline-powered vehicle, a gas-powered vehicle, or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle, a range-extender vehicle, etc. A battery 100 is installed inside the vehicle 1000, and the battery 100 may be installed at the bottom, head, or tail of the vehicle 1000. The battery 100 may be used to supply power to the vehicle 1000, for example, the battery 100 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may further include a controller 200 and a motor 300, and the controller 200 is used to control the battery 100 to supply power to the motor 300, for example, for starting the vehicle 1000, navigation, and operating power consumption needs during driving.

[0044] In some embodiments of the present application, the battery 100 can not only be the operating power source for the vehicle 1000, but can also be the driving power source for the vehicle 1000, providing driving power to the vehicle 1000 in place of or in place of fuel oil or natural gas.

[0045] Referring to FIG. 2, FIG. 2 is an exploded view of a battery 100 according to some embodiments of the present application. The battery 100 includes a housing 10 and battery cells 20 housed within the housing 10. Here, the housing 10 is used to provide a storage space for the battery cells 20, and the housing 10 may adopt various structures. In some embodiments, the housing 10 may include a first portion 11 and a second portion 12, which are fitted over each other and jointly define a storage space for accommodating the battery cells 20. The second portion 12 has a hollow structure with an open end. The first portion 11 may have a plate-like structure, and the first portion 11 is fitted over the open side of the second portion 12 to define the storage space together with the second portion 12. Both the first portion 11 and the second portion 12 may have a hollow structure with an open end, and the open side of the first portion 11 is fitted over the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 may have various shapes, such as a cylindrical body, a rectangular parallelepiped, or the like.

[0046] The battery 100 may include a plurality of battery cells 20, and the plurality of battery cells 20 may be connected in series, parallel, or series-parallel. A series-parallel connection means that the plurality of battery cells 20 may be connected in series or in parallel. The plurality of battery cells 20 may be directly connected in series, parallel, or series-parallel, and the entire battery set may be housed within the housing 10. Of course, the battery 100 may be formed by first connecting the plurality of battery cells 20 in series, parallel, or series-parallel to form a battery module, and then connecting the plurality of battery modules in series, parallel, or series-parallel to form an integrated battery module housed within the housing 10. The battery 100 may further include other structures; for example, the battery 100 may further include bus bar members for establishing electrical connection between the plurality of battery cells 20.

[0047] Here, each battery cell 20 may be a secondary battery or a primary battery, and may be, but is not limited to, a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery. The battery cells 20 may be cylindrical, flat, rectangular, or have other shapes.

[0048] According to some embodiments of the present application, with reference to Figures 2 to 4, an embodiment of the present application provides a housing 10 for installation on a main body of a power consumption device, the housing 10 includes a bottom plate 110 and a mounting beam 120, the bottom plate 110 has an outer wall surface 111, the mounting beam 120 is used to connect the main body, the mounting beam 120 includes a connecting portion 121, the connecting portion 121 is configured to be connected to the bottom plate 110, and at least a portion of the connecting portion 121 is attached to the outer wall surface 111.

[0049] Here, the bottom plate 110 is a base structure of the housing 10, and the bottom plate 110 is generally selectively a plate-like structure, and as can be understood, the bottom plate 110 may be, but is not limited to, an aluminum plate, a steel plate, an iron plate, an alloy plate, etc. Here, the outer wall surface 111 of the bottom plate 110 refers to the wall surface of the bottom plate 110 facing outward from the housing 10.

[0050] The main body of the power consuming device refers to the main structure of the power consuming device. For example, if the power consuming device is a vehicle 1000, the main body is the body of the vehicle 1000, and the housing 10 is connected to the body and assembled for use.

[0051] The mounting beam 120 is a beam structure that is installed on the bottom plate 110 and connects to the main body. The mounting beam 120 can be used to mount the housing 10 to the main body. Here, the connection between the mounting beam 120 and the main body may be achieved by fastening the mounting beam 120 to the corresponding portion of the main body with a fastener such as a bolt. The mounting beam 120 may be made of aluminum, steel, alloy, or the like, but is not limited thereto. The number of mounting beams 120 may be one or more. When there is one mounting beam 120, the mounting beam 120 may be installed at any one location on the outer wall surface 111 of the bottom plate 110 and connected to the bottom plate 110. When there are multiple mounting beams 120, the multiple mounting beams 120 may be arranged at intervals along the longitudinal direction of the bottom plate 110. For example, in some specific embodiments, the number of mounting beams 120 is one, and the mounting beam 120 is arranged along the central axis a of the bottom plate 110.

[0052] The mounting beam 120 includes a connecting portion 121, which is used to connect to the bottom plate 110 and bond to the outer wall surface 111 of the bottom plate 110. Alternatively, the connecting portion 121 may be an external structure attached to the mounting beam 120, such as a fin, a flat plate, or a support block. The structure can be attached to the mounting beam 120 by various methods, such as welding, gluing, or screwing. In this case, the number of connecting portions 121 may be one or more, or the connecting portion 121 may be a portion formed by a part of the mounting beam 120 for connecting to the bottom plate 110. For example, the connecting portion 121 may be a beam sidewall on one side of the mounting beam 120 facing the bottom plate 110. In this case, the surface area of ​​the beam sidewall can be increased by widening the mounting beam 120, thereby increasing the area bonded to the outer wall surface 111 of the bottom plate 110, or only the beam sidewall on one side can be widened to intentionally increase the surface area of ​​the beam sidewall on that side.

[0053] Here, the connection portion 121 is connected to the bottom plate 110, and optionally, the connection between the connection portion 121 and the bottom plate 110 may be realized by welding, gluing, screwing, etc. For example, in some specific embodiments, the connection portion 121 may be connected to the bottom plate 110 by spot welding to form an integral unit.

[0054] At least a portion of the connection portion 121 is attached to the outer wall surface 111, and as can be understood, the side wall of the connection portion 121 facing the outer wall surface 111 may be completely attached to the outer wall surface 111, or a bent structure or relief structure may be formed in the connection portion 121 so that a portion of the connection portion 121 is attached to the outer wall surface 111.

[0055] The housing 10 according to an embodiment of the present application may be connected to the main body of the power consuming device via a mounting beam 120, wherein the mounting beam 120 is connected and attached to the bottom plate 110 via a connection portion 121, and the mounting beam 120 can distribute stress between the bottom plate 110 and the mounting beam 120 by installing the connection portion 121, thereby reducing the risk of breakage occurring between the bottom plate 110 and the connection portion 121, and making the housing 10 more reliable when mounted on the main body of the power consuming device via the mounting beam 120 and used.

[0056] According to some embodiments of the present application, referring to FIGS. 2 to 5, the mounting beam 120 further includes a beam body 122 for connecting to the body, and the connecting portion 121 is installed on the beam body 122.

[0057] As can be understood, the beam body 122 refers to the beam structural part of the mounting beam 120, and the connection part 121 may be installed on the beam body 122, for example, by welding, screwing, or adhesive bonding to achieve a fixed connection with the beam body 122, or be integrally molded with the beam body 122.

[0058] Here, the beam body 122 may adopt an aluminum extrusion structure, and the beam body 122 is used to connect to the main body. Optionally, a connection hole (through hole, screw hole, etc.) may be opened in the beam body 122, and fasteners such as bolts and screws may be used to drill into the connection hole and fix the beam body 122 to the main body.

[0059] By installing it in this manner, when the housing 10 is mounted on the main body using the mounting beam 120, the beam body 122 of the mounting beam 120 can be connected to the main body, and the connection part 121 of the mounting beam 120 is installed on the beam body 122 and connected to the outer wall surface 111 of the bottom plate 110 and bonded together to distribute the acting force, thereby reducing the probability of breakage occurring between the mounting beam 120 and the bottom plate 110 when the housing 10 is mounted on the main body.

[0060] According to some embodiments of the present application, with reference to FIGS. 2, 4 to 8, the connector 121 extends outside and beyond the beam body 122.

[0061] As can be understood, the connecting portion 121 extends outward and exceeds the beam body 122, and the connecting portion 121 may extend in any direction outside the beam body 122 and exceed the beam body 122, and then be connected to the bottom plate 110 via the connecting portion 121, thereby realizing stress distribution between the bottom plate 110 and the connecting portion 121. Here, the connecting portion 121 may be located on one side of the beam body 122 and extend out of the beam body 122, or the connecting portion 121 may extend out of the beam body 122 on opposite sides of the beam body 122 at the same time.

[0062] For example, in some specific embodiments, in a direction parallel to the outer wall surface 111 and perpendicular to the longitudinal direction L of the beam body 122, the connection portion 121 can extend outward from and exceed the beam body 122, so that the connection portion 121 has a larger surface area, i.e., the bonding area between the connection portion 121 and the outer wall surface 111 of the bottom plate 110 is larger, thereby distributing the stress between the bottom plate 110 and the mounting beam 120 and reducing the risk of breakage occurring between the bottom plate 110 and the connection portion 121.

[0063] By installing it in this manner, the connection part 121 can extend beyond the beam body 122, i.e., the connection part 121 has a larger bonding area with the outer wall surface 111 of the bottom plate 110, and the effect of dispersing the force acting on the bottom plate 110 of the connection part 121 is better, so that the risk of breakage occurring between the mounting beam 120 and the bottom plate 110 is lower, and the housing 10 is mounted more stably on the main body.

[0064] According to some embodiments of the present application, referring to FIGS. 2, 4 and 5, the beam body 122 is spaced apart from the outer wall surface 111.

[0065] As can be understood, when the connection portion 121 is connected by pasting it to the outer wall surface 111, the beam main body 122 is spaced apart from the outer wall surface 111, i.e., one side surface of the connection portion 121 for pasting it to the outer wall surface 111 and one side surface of the beam main body 122 facing the outer wall surface 111 form a step in the thickness direction N of the bottom plate 110.Optionally, the connection portion 121 may be fixed and connected to one side surface of the beam main body 122 facing the outer wall surface 111, thereby allowing the connection portion 121 to form the above-mentioned step according to its own thickness.

[0066] By installing it in this manner, when the connection part 121 of the mounting beam 120 is connected to the bottom plate 110 and attached to the outer wall surface 111 of the bottom plate 110, a gap is formed between the beam body 122 of the mounting beam 120 and the outer wall surface 111 of the bottom plate 110, thereby allowing the beam body 122 to act as a relief against the outer wall surface 111 of the bottom plate 110, reducing the risk of interference between the beam body 122 and the structure installed on the outer wall surface 111 of the bottom plate 110.

[0067] According to some embodiments of the present application, referring to Figures 2, 4 and 5, an attachment structure 1221 is installed on the beam body 122, and the beam body 122 is configured to be connected to the body via the attachment structure 1221, and along the thickness direction N of the bottom plate 110, the projection of the attachment structure 1221 is located within the projection of the connection portion 121.

[0068] As can be understood, the above-mentioned mounting structure 1221 may be a mounting hole (such as a screw hole, a through hole, etc.), and the beam body 122 may be connected to the body through this mounting hole using a fastener such as a bolt or a screw, or the mounting structure 1221 may be a welded area portion used for welding, and the welded area portion and the body may be welded together through a welding process to form a single unit.

[0069] By installing the mounting beam 120 in this manner, if the beam body 122 of the mounting beam 120 is connected to the main body via the mounting structure 1221, when the main body vibrates, the housing 10 will vibrate relative to the main body, and as a result, the entire weight of the housing 10 will generate a relatively large acting force between the mounting structure 1221 and the main body. At the same time, vibrations will also occur between the connection part 121 of the mounting beam 120 and the bottom plate 110, generating a relatively large acting force. By installing the mounting structure 1221 so that the projection of the bottom plate 110 in the thickness direction N is located inside the connection part 121, the mounting structure 1221 can be installed so that the projection of the bottom plate 110 in the thickness direction N is located inside the connection part 121. The acting force between the mounting structure 1221 almost overlaps with the position of the acting force between the connection part 121 and the bottom plate 110 in the thickness direction N of the bottom plate 110, thereby effectively reducing the acting force between the main body and the mounting structure 1221 and the acting force between the connection part 121 and the bottom plate 110 from forming a lever effect on the mounting beam 120, and reducing the stress between the mounting beam 120 and the main body and bottom plate 110 connected to the mounting beam 120, making it less likely that breakage will occur between the mounting beam 120 and the bottom plate 110, and the housing 10 is more stably mounted on the main body.

[0070] According to some embodiments of the present application, referring to Figures 6 to 8, Figure 6 is a structural schematic diagram of another base plate 110 according to some embodiments of the present application, where the base plate 110 in Figure 6 can be adapted to the mounting beam 120 in Figure 7, the mounting beam 120 in Figure 8, or other types of mounting beams 120 to meet needs, and therefore the base plate 110 in Figure 6 does not show the structure of a specific mounting beam 120.

[0071] In this embodiment, the beam body 122 abuts against the outer wall surface 111 .

[0072] As can be understood, when the connection portion 121 is attached to the outer wall surface 111 and connected, the beam body 122 abuts against the outer wall surface 111, that is, the side surface of the connection portion 121 for attaching to the outer wall surface 111 is flush with the side surface of the beam body 122 facing the outer wall surface 111 in the thickness direction N of the bottom plate 110; optionally, a groove can be formed in the beam body 122, and the connection portion 121 can be fixed and installed in the groove so that the surface of the beam body 122 and the surface of the connection portion 121 are flush with each other; or the connection portion 121 can be fixed and installed on a surface of the beam body 122 that intersects with the outer wall surface 111, and the side surface of the connection portion 121 for attaching to the outer wall surface 111 is flush with the side surface of the beam body 122 facing the outer wall surface 111.

[0073] By installing it in this manner, the connection part 121 of the mounting beam 120 can be connected to and at least partially attached to the outer wall surface 111 of the bottom plate 110, and the beam body 122 can further abut against the outer wall surface 111, thereby effectively increasing the contact area between the mounting beam 120 and the bottom plate 110; that is, the mounting beam 120 can simultaneously distribute the acting force with the bottom plate 110 through the beam body 122 and the connection part 121, further reducing the risk of breakage occurring between the mounting beam 120 and the bottom plate 110.

[0074] According to some embodiments of the present application, with reference to FIGS. 2 to 5, the entire connecting portion 121 is configured to be installed symmetrically with respect to the central axis of the beam body 122.

[0075] Alternatively, the connection portion 121 may be arranged symmetrically with respect to the beam body 122 along the central axis b of the beam body 122 in its longitudinal direction L, or the connection portion 121 may be arranged symmetrically with respect to the central axis c perpendicular to the longitudinal direction L of the beam body 122, as shown in Figure 5, the connection portion in Figure 5 is symmetrical with respect to the central axis b of the beam body 122 along its longitudinal direction L, and at the same time is symmetrical with respect to the central axis c perpendicular to the longitudinal direction L of the beam body 122.

[0076] By installing it in this manner, the connection part 121 utilizes a symmetrical distribution structure with respect to the beam body 122, and the process of the force acting between the main body and the beam body 122 being transmitted between the connection part 121 and the bottom plate 110 becomes more uniform, thereby improving the effect of distributing the force acting on the bottom plate 110 of the connection part 121 and reducing the risk of breakage occurring between the mounting beam 120 and the bottom plate 110.

[0077] According to some embodiments of the present application, referring to FIGS. 2 to 5, the bottom plate 110 has a beam body 122 disposed along its central axis a.

[0078] Here, the central axis a of the bottom plate 110 refers to an auxiliary line that can divide the bottom plate 110 into two symmetrical parts, and the beam body 122 is disposed along the central axis a of the bottom plate 110.

[0079] As can be understood, when the body of the power consumption device vibrates, since the beam body 122 of the mounting beam 120 is fixedly connected to the body, a certain degree of vibration is also formed between the connection part 121 of the mounting beam 120 and the bottom plate 110, thereby generating stress between the connection part 121 and the bottom plate 110.

[0080] By installing it in this manner, when the main body vibrates, the housing 10 also vibrates relative to the main body, and the mounting beam 120 is connected to the main body, which corresponds to other parts of the housing 10 vibrating relative to the mounting beam 120. The beam body 122 of the mounting beam 120 is arranged along the central axis a of the bottom plate 110, i.e., the mounting beam 120 is located at the center of amplitude of the bottom plate 110, and the connection part 121 of the mounting beam 120 receives the acting force of the bottom plate 110 more evenly, which can to some extent mitigate the risk of the mounting beam 120 breaking.

[0081] Optionally, mounting beams may be further installed at both ends of the outer wall surface 111 of the bottom plate 110 relative to the central axis a, and the housing 10 can be fixed and connected to the main body by the mounting beams, so that it can be mounted and used in synchronization with the mounting beams 120.

[0082] According to some embodiments of the present application, referring to FIGS. 2 to 5, the number of the connection portions 121 is plural, and the plurality of connection portions 121 are installed at intervals.

[0083] Here, the multiple connection portions 121 may be spaced apart in any direction; for example, the multiple connection portions 121 may be arranged at intervals in the longitudinal direction L of the beam body 122, or the multiple connection portions 121 may be further arranged at intervals in the longitudinal direction L perpendicular to the beam body 122, for example, distributed on opposite sides of the beam body 122.

[0084] By installing it in this manner, it is possible to connect and attach it to the bottom plate 110 using multiple connecting parts 121 installed at intervals, and the multiple connecting parts 121 distribute the acting force of the bottom plate 110, effectively reducing the risk of breakage occurring between the connecting parts 121 and the bottom plate 110.

[0085] According to some embodiments of the present application, referring to Figures 6, 9 and 10, the mounting beam 120 further includes a beam body 122, the portion of the beam body 122 facing the outer wall surface 111 forms a connection portion 121, and the portion of the beam body 122 facing away from the outer wall surface 111 forms a mounting portion, which is used to connect the body, and along the thickness direction N of the bottom plate 110, the projection of the mounting portion is located within the projection of the connection portion 121.

[0086] Here, the portion of the beam body 122 facing the outer wall surface 111 forms the connection portion 121, i.e., the connection portion 121 belongs to a part of the beam body 122. By improving the beam body 122 itself, the projection of the mounting portion is located within the projection of the connection portion 121 in the thickness direction N of the bottom plate 110, i.e., the surface area of ​​one side of the connection portion 121 is increased, and a larger bonding area is achieved between the connection portion 121 and the outer wall surface 111 of the bottom plate 110. This improves the effect of dispersing the force acting on the bottom plate 110 of the connection portion 121, thereby reducing the risk of breakage between the mounting beam 120 and the bottom plate 110.

[0087] Alternatively, the projection of the mounting portion may be located within the projection of the connecting portion 121 in the thickness direction N of the bottom plate 110 in the following manner: the beam body 122 is installed as a trapezoidal beam, i.e., the cross section of the beam body 122 is trapezoidal, and one of the two parallel side walls of the trapezoidal beam that is relatively larger than the outer wall is used as the connecting portion 121; or the beam body 122 is installed as a convex beam, i.e., the cross section of the beam body 122 is approximately "convex", and one of the relatively larger than the outer wall of the convex beam is used as the connecting portion 121; or the beam body 122 is designed to be wider overall, thereby increasing the surface area of ​​the outer wall of the beam body 122 that is used as the connecting portion 121.

[0088] By installing it in this manner, the projection of the mounting portion is installed so as to be located within the projection of the connection portion 121 in the direction of the bottom plate 110, i.e., the area of ​​the connection portion 121 is larger than the area of ​​the mounting portion, and the connection and bonding with the bottom plate 110 is realized by using the connection portion 121 with a larger area, and the acting force of the bottom plate 110 on the connection portion 121 can be distributed, thereby effectively reducing the risk of breakage occurring between the connection portion 121 and the bottom plate 110.

[0089] According to some embodiments of the present application, referring to Figures 2 to 5, a flow path 1101 is provided in the bottom plate 110, a heat exchange medium is contained in the flow path 1101, and a projection of the flow path 1101 and a projection of the connection portion 121 are separated from each other along the thickness direction N of the bottom plate 110.

[0090] Here, the flow path 1101 is used to flow the heat exchange medium and exchange heat between the heat exchange medium and the structure (e.g., the battery cell 20) inside the housing 10, thereby achieving the purpose of lowering the temperature. Alternatively, the heat exchange medium may be a liquid medium, such as cooling water or cooling oil.

[0091] Alternatively, the flow channel 1101 may be formed using an inflation process, i.e., the base plate 110 may be an inflation cold panel formed by an inflation process. According to the inflation cold panel process, the mass of the inflation cold panel is relatively small, so that using the inflation cold panel as the base plate 110 can reduce the overall weight of the enclosure 10.

[0092] As can be understood, the bottom plate 110 can also be a brazed cold plate formed by a pressing process, specifically as shown in FIG. 6, where the bottom plate 110 shown in FIG. 6 does not include a flow path 1101, so that the bottom plate 110 can fill the mounting beam 120 of the connection portion 121 with a larger surface area, and optionally, the bottom plate 110 in FIG. 6 can also be applied to the mounting beam 120 in FIG. 5, FIG. 7, FIG. 9, FIG. 10 or the mounting beam 120 of other structures, but is not limited thereto.

[0093] By installing them in this manner, the flow path 1101 and the connection part 121 are spaced apart in the thickness direction of the bottom plate 110, and damage to the flow path 1101 due to the force acting between the connection part 121 and the bottom plate 110 can be reduced.

[0094] For example, in some specific embodiments, the housing 10 includes a bottom plate 110 and a mounting beam 120. The bottom plate 110 is preferably an inflation cold panel, and a flow path 1101 is formed in the bottom plate 110 by an inflation process. The mounting beam 120 includes a beam body 122 and a connecting portion 121. The connecting portion 121 uses fins, and a plurality of fins are integrally formed on one side of the beam body 122 facing the bottom plate 110. The plurality of fins are spaced apart along the longitudinal direction L of the beam body 122. The fins may be rectangular fins, and the fins extend from the range of the beam body 122 along a direction parallel to the outer wall surface 111 and perpendicular to the longitudinal direction L of the beam body 122. When assembled, the beam body 122 is attached to the bottom plate 110. 10 along the central axis a of the fin 122, and each fin is attached to the outer wall surface 111 of the bottom plate 110 and spot welded to form a single unit, where the attachment points between the fins and the outer wall surface 111 must avoid the flow paths 1101 formed on the bottom plate 110. For example, the fins may be attached to the gaps between the flow paths 1101 or the outer peripheral areas of the flow paths 1101, whereby a gap is formed between the beam body 122 and the outer wall surface 111, allowing the beam body 122 to avoid the flow paths 1101. The connection between the fins and the bottom plate 110 can be used to distribute stress between the bottom plate 110 and the mounting beam 120, effectively reducing the risk of breakage between the bottom plate 110 and the mounting beam 120.

The battery 100 according to the embodiments of the present application includes the above-described housing 10, and when the risk of breakage occurring between the mounting beam 120 and the bottom plate 110 of the housing 10 is relatively low, the overall structure of the battery 100 is more stable.
