Description

Technical Field

[0001] This application relates to the field of battery structure technology, and in particular provides a housing, a battery, and an electrical device. Background Technology

[0002] When batteries are mounted and used, they are connected to the main body of the electrical equipment via beam structures on the battery casing, thus securing the battery to the main body of the equipment such as vehicles, airplanes, and ships. However, during operation, the electrical equipment may vibrate, causing the battery to vibrate relative to the main body. Therefore, the stress between the beam structure and the base plate of the casing is relatively high, and the risk of fracture between the beam structure and the base plate is relatively high. Summary of the Invention

[0003] The purpose of this application is to provide a housing, battery, and electrical equipment, aiming to solve the problem in the related art that large stress may be generated between the beam structure and the base plate during the mounting and use of the housing, and that the beam structure and the base plate are prone to breakage.

[0004] To achieve the above objectives, the technical solution adopted in the embodiments of this application is as follows:

[0005] In a first aspect, embodiments of this application provide a housing for mounting on the main body of an electrical device. The housing includes a base plate and a mounting beam. The base plate has an outer wall surface, and the mounting beam is used to connect to the main body. The mounting beam includes a connecting portion, which is configured to connect to the base plate, and at least a portion of the connecting portion is in contact with the outer wall surface.

[0006] The beneficial effects of the embodiments of this application are as follows: The enclosure provided in the embodiments of this application can be connected to the main body of the electrical equipment by a mounting beam. The mounting beam is connected to and fits against the bottom plate through a connecting part. The mounting beam can increase the contact area with the bottom plate by setting the connecting part. The larger contact area between the bottom plate and the connecting part can disperse the stress between the bottom plate and the mounting beam, that is, the risk of fracture between the bottom plate and the connecting part is lower. The enclosure is more reliable when it is used by hanging on the main body of the electrical equipment through the mounting beam.

[0007] In some embodiments, the mounting beam further includes a beam body for connection to the main body, and a connecting portion is disposed on the beam body.

[0008] By adopting the above technical solution, when the box body is mounted on the main body using the mounting beam, the beam body of the mounting beam can be connected to the main body. The connection part of the mounting beam is set on the beam body and connected and fitted to the outer wall surface of the bottom plate to disperse stress, which can reduce the probability of breakage between the mounting beam and the bottom plate when the box body is mounted on the main body.

[0009] In some embodiments, the connection extends outward from the beam body and beyond the beam body.

[0010] By adopting the above technical solution, the connecting part can extend beyond the beam body, that is, the connecting part has a larger contact area with the outer wall of the base plate, and the force distribution effect of the connecting part on the base plate is better, thus reducing the risk of breakage between the installed beam and the base plate, and making the box body more stable when mounted on the main body.

[0011] In some embodiments, the beam body and the outer wall surface are spaced apart.

[0012] By adopting the above technical solution, when the connecting part of the mounting beam is connected to the base plate and fits against the outer wall surface of the base plate, the beam body of the mounting beam will form a gap with the outer wall surface of the base plate, so that the beam body can avoid the outer wall surface of the base plate, which can reduce the risk of interference between the beam body and the structure set on the outer wall surface of the base plate.

[0013] In some embodiments, a mounting structure is provided on the beam body, and the beam body is configured to be connected to the main body via the mounting structure; along the thickness direction of the base plate, the projection of the mounting structure is located within the projection of the connection portion.

[0014] By adopting the above technical solution, when the beam body of the mounting beam is connected to the main body through the mounting structure, the main body may vibrate, causing the box body to vibrate relative to the main body. This results in the overall weight of the box body exerting a large force on the mounting structure and the main body. At the same time, the connection part of the mounting beam and the bottom plate will also vibrate to a certain extent, generating a large force. By setting the mounting structure so that its projection in the thickness direction of the bottom plate is located inside the connection part, the force between the main body and the mounting structure and the force between the connection part and the bottom plate roughly coincide in the thickness direction of the bottom plate. This effectively reduces the leverage formed by the force between the main body and the mounting structure and the force between the connection part and the bottom plate on the mounting beam, reducing damage to the mounting beam and the main body and bottom plate connected to the mounting beam. The risk of breakage between the mounting beam and the bottom plate is lower, and the box body is more stable when mounted on the main body.

[0015] In some embodiments, the beam body abuts against the outer wall surface.

[0016] By adopting the above technical solution, the connection part of the mounting beam can be connected to and at least partially attached to the outer wall surface of the base plate, and the beam body can also abut against the outer wall surface, thereby effectively increasing the contact area between the mounting beam and the base plate. That is, the mounting beam can simultaneously disperse the force with the base plate through the beam body and the connection part, further reducing the risk of breakage between the mounting beam and the base plate.

[0017] In some embodiments, the connection portion is configured to be symmetrical about the central axis of the beam body.

[0018] By adopting the above technical solution, the process of transferring the force between the main body and the beam body to the connection part and the bottom plate is more even, so the force distribution effect of the connection part on the bottom plate is better, and the risk of breakage between the installed beam and the bottom plate is lower.

[0019] In some embodiments, the base plate is provided with beam bodies along its central axis.

[0020] By adopting the above technical solution, when the main body vibrates, the box body also vibrates relative to the main body. The mounting beam is connected to the main body, which is equivalent to the other parts of the box body vibrating relative to the mounting beam. The beam body of the mounting beam is arranged on the central axis of the bottom plate, that is, the mounting beam is located at the center of the amplitude of the bottom plate. The connection part of the mounting beam is subjected to the force of the bottom plate more evenly, thereby mitigating the risk of the mounting beam breaking to a certain extent.

[0021] In some embodiments, the number of connecting parts is multiple, and the multiple connecting parts are spaced apart.

[0022] By adopting the above technical solution, multiple spaced connecting parts can be used to connect and fit with the base plate, and the force exerted on the base plate can be dispersed through multiple connecting parts, which can effectively reduce the risk of breakage between the connecting parts and the base plate.

[0023] In some embodiments, the mounting beam further includes a beam body, with a portion of the beam body facing the outer wall forming a connecting portion and a portion of the beam body facing away from the outer wall forming a mounting portion. The mounting portion is used to connect to the main body, and the projection of the mounting portion is located within the projection of the connecting portion along the thickness direction of the base plate.

[0024] By adopting the above technical solution, the projection of the mounting part is set to be located within the projection of the connecting part in the direction of the base plate. That is, the area of ​​the connecting part is larger than the area of ​​the mounting part. The larger area of ​​the connecting part is used to achieve connection and fit with the base plate, which can disperse the force of the base plate on the connecting part, thereby effectively reducing the risk of breakage between the connecting part and the base plate.

[0025] In some embodiments, the base plate is provided with a flow channel, which contains a heat exchange medium, and the projection of the flow channel and the projection of the connection portion are separated from each other along the thickness direction of the base plate.

[0026] By adopting the above technical solution, the flow channel and the connecting part can be separated in the thickness direction of the base plate, reducing the impact of the connecting part on the flow channel.

[0027] Secondly, embodiments of this application also provide a battery, including a battery cell and a housing as described above, wherein the battery cell is located inside the housing.

[0028] The beneficial effects of the embodiments of this application are as follows: The battery provided by the embodiments of this application includes the above-mentioned housing, and the overall structure of the battery is more stable with a lower risk of breakage between the mounting beam and the bottom plate of the housing.

[0029] Thirdly, embodiments of this application also provide an electrical device, including a main body and a battery as described above, wherein the battery housing is disposed on the main body and the battery is used to provide electrical energy.

[0030] The beneficial effects of the embodiments of this application are as follows: The electrical equipment provided in the embodiments of this application includes the battery described above. With a more stable overall battery structure, the process of the battery being mounted on the main body and providing power to the main body is more stable, and the risk of the battery falling off the main body is lower.

[0049] The embodiments of this application are described in detail below.

The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0050] In the description of this application, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0051] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0052] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0053] Currently, judging from market trends, the application of power batteries is becoming increasingly widespread. Power batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively used in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of power battery applications, market demand is also constantly increasing.

[0054] When a battery is mounted, it is connected to the main body of the electrical equipment via beam structures on the battery casing. This allows the battery to be mounted and fixed to the main body of the equipment, such as vehicles, airplanes, and ships, and to provide power to the equipment. However, during operation, the electrical equipment may vibrate; for example, a vehicle may experience bumps during operation. This will cause a certain amount of vibration between the connected main body and the battery, generating stress between the beam structures on the battery casing and the main body. Since the beam structure is connected to the base plate of the casing, it will also vibrate and generate significant stress. Due to the relatively high structural strength of the beam structure, it can withstand the stress generated between it and the main body, and the probability of beam structure breakage is low. However, the stress generated between the beam structure and the base plate is more likely to cause breakage between the beam structure and the base plate, or damage such as deformation and cracking of the base plate.

[0055] Based on the above considerations, in order to solve the problem that large stress may be generated between the beam structure and the bottom plate during the installation and use of the box body in related technologies, and the beam structure and the bottom plate are prone to breakage, a box body is designed. It uses the connection part of the mounting beam to connect with the bottom plate, and at least part of the connection part is attached to the outer wall surface of the bottom plate. The connection part is used to increase the contact area with the bottom plate, thereby dispersing the stress between the mounting beam and the bottom plate, so as to effectively reduce the probability of breakage, damage, deformation and other risks between the mounting beam and the bottom plate.

[0056] In this enclosure, a connecting part is used to connect to the base plate, and the connecting part is in close contact with the outer wall surface of the base plate. During the installation and use of the enclosure, when the main body of the electrical equipment vibrates, the base plate will also vibrate to a certain extent relative to the mounting beam, thus generating stress between the base plate and the mounting beam. The connection method of the connecting part being in close contact with the outer wall surface of the base plate can disperse the stress between the base plate and the mounting beam, thereby reducing the impact of stress concentration and lowering the risk of deformation, breakage, or other damage between the mounting beam and the base plate caused by stress concentration. This makes the structure of the enclosure more stable during use, thereby increasing the service life of the enclosure.

[0057] The enclosure disclosed in this application can be used in electrical devices that use batteries as a power source or in various energy storage systems that use batteries as energy storage elements. Electrical devices can be, but are not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0058] For ease of explanation, the following embodiments will be described using a vehicle 1000 as an example of an electrical device according to an embodiment of this application.

[0059] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery 100 is disposed inside the vehicle 1000, and the battery 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery 100 can be used to power the vehicle 1000; for example, the battery 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 200 and a motor 300. The controller 200 is used to control the battery 100 to supply power to the motor 300, for example, to meet the power needs of the vehicle 1000 during startup, navigation, and driving.

[0060] In some embodiments of this application, the battery 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0061] Please refer to Figure 2 , Figure 2This is an exploded view of a battery 100 provided in some embodiments of this application. The battery 100 includes a housing 10 and a battery cell 20, with the battery cell 20 housed within the housing 10. The housing 10 provides a space for the battery cell 20 and can have various structures. In some embodiments, the housing 10 may include a first portion 11 and a second portion 12, which overlap each other, jointly defining a space for accommodating the battery cell 20. The second portion 12 may be a hollow structure with one open end, and the first portion 11 may be a plate-like structure, covering the open side of the second portion 12 so that the first portion 11 and the second portion 12 jointly define the space; alternatively, the first portion 11 and the second portion 12 may both be hollow structures with one open side, with the open side of the first portion 11 covering the open side of the second portion 12. Of course, the housing 10 formed by the first portion 11 and the second portion 12 can have various shapes, such as a cylinder, a cuboid, etc.

[0062] In battery 100, there can be multiple battery cells 20, which can be connected in series, parallel, or in a mixed manner. A mixed connection means that multiple battery cells 20 are connected in both series and parallel configurations. Multiple battery cells 20 can be directly connected in series, parallel, or in a mixed manner, and then the entire assembly of the multiple battery cells 20 is housed within the housing 10. Alternatively, battery 100 can also be composed of multiple battery cells 20 first connected in series, parallel, or in a mixed manner to form a battery module, and then multiple battery modules are connected in series, parallel, or in a mixed manner to form a whole, which is also housed within the housing 10. Battery 100 may also include other structures; for example, it may include a busbar component for electrical connection between the multiple battery cells 20.

[0063] Each battery cell 20 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 to these. The battery cell 20 can be cylindrical, flat, cuboid, or other shapes.

[0064] According to some embodiments of this application, please refer to Figures 2 to 4 This application provides a housing 10 for mounting on the main body of an electrical device. The housing 10 includes a base plate 110 and a mounting beam 120. The base plate 110 has an outer wall surface 111. The mounting beam 120 is used to connect to the main body and includes a connecting portion 121. The connecting portion 121 is configured to connect to the base plate 110, and at least a portion of the connecting portion 121 is in contact with the outer wall surface 111.

[0065] The base plate 110 is the base structure of the housing 10. The base plate 110 is generally a plate structure. Understandably, the base plate 110 can be, but is not limited to, aluminum plate, steel plate, iron plate, alloy plate, etc. The outer wall surface 111 of the base plate 110 refers to the side wall surface of the base plate 110 facing the outside of the housing 10.

[0066] The main body of electrical equipment refers to the main structure of the electrical equipment. For example, when the electrical equipment is vehicle 1000, its main body is the body of vehicle 1000, and the box 10 is connected to the body for assembly and use.

[0067] The mounting beam 120 is a beam structure installed on the base plate 110 and used to connect the main body. The mounting beam 120 can hang the box body 10 on the main body for use. The connection between the mounting beam 120 and the main body can be achieved by fixing the corresponding parts of the mounting beam 120 and the main body with fasteners such as bolts. The mounting beam 120 can be, but is not limited to, aluminum beams, steel beams, alloy beams, etc. The number of mounting beams 120 can be one or more. When there is only one mounting beam 120, it can be installed at any point on the outer wall surface 111 of the base plate 110 and connected to the base plate 110. When there are multiple mounting beams 120, they can be arranged at intervals along the length of the base plate 110. For example, in some specific embodiments, there is only one mounting beam 120, and it is arranged along the central axis a of the base plate 110.

[0068] The mounting beam 120 includes a connecting portion 121, which is used to connect to the base plate 110 and can fit against the outer wall surface 111 of the base plate 110. Optionally, the connecting portion 121 can be an external structure provided on the mounting beam 120, such as a fin, plate, support block, etc. The above-mentioned structure can be provided on the mounting beam 120 by welding, bonding, screwing, etc. In this case, the number of connecting portions 121 can be one or more. Alternatively, the connecting portion 121 can also be a part formed locally by the mounting beam 120 for connecting with the base plate 110. For example, the connecting portion 121 can be the beam sidewall of the mounting beam 120 facing the base 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 that fits against the outer wall surface 111 of the base plate 110, or the surface area of ​​the beam sidewall on only one side can be specifically increased.

[0069] The connecting part 121 is connected to the base plate 110. Optionally, the connecting part 121 and the base plate 110 can be connected by welding, bonding, screwing or other means. For example, in some specific embodiments, the connecting part 121 can be connected to the base plate 110 by spot welding to form an integral part.

[0070] At least a portion of the connecting portion 121 is in contact with the outer wall surface 111. Understandably, the sidewall of the connecting portion 121 facing the outer wall surface 111 can be completely in contact with the outer wall surface 111; or, a bending structure or a clearance structure can be formed on the connecting portion 121 so that a portion of the connecting portion 121 is in contact with the outer wall surface 111.

[0071] The enclosure 10 provided in this embodiment can be connected to the main body of the electrical equipment via a mounting beam 120. The mounting beam 120 is connected to and fits against the base plate 110 via a connecting part 121. The mounting beam 120 can distribute the stress between the base plate 110 and the mounting beam 120 by setting the connecting part 121, thereby reducing the risk of breakage between the base plate 110 and the connecting part 121. The enclosure 10 is more reliable when it is mounted on the main body of the electrical equipment via the mounting beam 120.

[0072] According to some embodiments of this application, please refer to Figures 2 to 5 The mounting beam 120 also includes a beam body 122, which is used to connect to the main body, and a connecting part 121 is provided on the beam body 122.

[0073] Understandably, the beam body 122 refers to the beam structure part on which the beam 120 is installed. The connecting part 121 can be set on the beam body 122, for example, by welding, screwing, or bonding to achieve a fixed connection with the beam body 122, or it can be integrally formed on the beam body 122.

[0074] The beam body 122 can be made of extruded aluminum. The beam body 122 is used to connect to the main body. Optionally, connecting holes (through holes, threaded holes, etc.) can be opened on the beam body 122, and fasteners such as bolts and screws can be inserted through the connecting holes to fix the beam body 122 to the main body.

[0075] With this configuration, when the box 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. The connecting part 121 of the mounting beam 120 is located on the beam body 122 and is connected to and fits against the outer wall surface 111 of the base plate 110 to disperse the force, thereby reducing the probability of breakage between the mounting beam 120 and the base plate 110 when the box 10 is mounted on the main body.

[0076] According to some embodiments of this application, please refer to Figure 2 , Figures 4 to 8 The connecting part 121 extends outward from the beam body 122 and beyond the beam body 122.

[0077] Understandably, the connecting portion 121 extends outward beyond the beam body 122. The connecting portion 121 can extend in any direction outside the beam body 122 and then connect to the base plate 110, thereby achieving stress dispersion between the base plate 110 and the connecting portion 121. The connecting portion 121 can be located on one side of the beam body 122 and extend outward, or it can extend outward simultaneously from both opposite sides of the beam body 122.

[0078] For example, in some specific embodiments, the connecting portion 121 can extend outward and beyond the beam body 122 in a direction parallel to the outer wall surface 111 and perpendicular to the length direction L of the beam body 122, so that the connecting portion 121 has a larger surface area, that is, the area of ​​the connecting portion 121 in contact with the outer wall surface 111 of the base plate 110 can be larger, thereby dispersing the stress between the base plate 110 and the mounting beam 120, so as to reduce the risk of fracture between the base plate 110 and the connecting portion 121.

[0079] With this configuration, the connecting part 121 can extend beyond the beam body 122, meaning that the connecting part 121 has a larger contact area with the outer wall surface 111 of the base plate 110. The connecting part 121 has a better effect on dispersing the force on the base plate 110, thus reducing the risk of breakage between the mounting beam 120 and the base plate 110, and making the box 10 more stable when mounted on the main body.

[0080] According to some embodiments of this application, please refer to Figure 2 , Figure 4 and Figure 5 The beam body 122 and the outer wall surface 111 are spaced apart.

[0081] Understandably, when the connecting part 121 is attached to and connected to the outer wall surface 111, the beam body 122 is spaced apart from the outer wall surface 111; that is, the side surface of the connecting part 121 that is attached to the outer wall surface 111 and the side surface of the beam body 122 facing the outer wall surface 111 form a height difference in the thickness direction N of the base plate 110; optionally, the connecting part 121 can be fixedly connected to the side surface of the beam body 122 facing the outer wall surface 111, so that the connecting part 121 forms the above-mentioned height difference according to its own thickness.

[0082] With this configuration, when the connecting part 121 of the mounting beam 120 is connected to the base plate 110 and fits against the outer wall surface 111 of the base plate 110, the beam body 122 of the mounting beam 120 will form a gap with the outer wall surface 111 of the base plate 110. Thus, the beam body 122 can avoid the outer wall surface 111 of the base plate 110, which can reduce the risk of interference between the beam body 122 and the structure installed on the outer wall surface 111 of the base plate 110.

[0083] According to some embodiments of this application, please refer to Figure 2 , Figure 4 and Figure 5 An installation structure 1221 is provided on the beam body 122, and the beam body 122 is configured to be connected to the main body through the installation structure 1221; along the thickness direction N of the base plate 110, the projection of the installation structure 1221 is located within the projection of the connection part 121.

[0084] Understandably, the aforementioned mounting structure 1221 can be a mounting hole (threaded hole, through hole, etc.), through which the beam body 122 can be connected to the main body using fasteners such as bolts and screws; or, the mounting structure 1221 can also be a weldable area for welding, which can be welded to the main body to form an integral part through welding process.

[0085] With this configuration, when the beam body 122 of the mounting beam 120 is connected to the main body via the mounting structure 1221, vibration of the main body causes the box 10 to vibrate relative to the main body, resulting in a significant force exerted by the overall weight of the box 10 on the mounting structure 1221 and the main body. Simultaneously, vibration also occurs between the connecting portion 121 of the mounting beam 120 and the base plate 110, generating a significant force. By positioning the mounting structure 1221 so that its projection in the thickness direction N of the base plate 110 is located inside the connecting portion 121, the main body and the mounting structure 1221... The forces between 221 and the forces between the connecting part 121 and the base plate 110 are approximately coincident in the thickness direction N of the base plate 110. This effectively reduces the forces between the main body and the mounting structure 1221, as well as between the connecting part 121 and the base plate 110, which form a lever on the mounting beam 120. This reduces the stress on the mounting beam 120 and the main body and base plate 110 connected to the mounting beam 120. The risk of breakage between the mounting beam 120 and the base plate 110 is lower, and the box 10 is more stable when mounted on the main body.

[0086] According to some embodiments of this application, please refer to Figures 6 to 8 , Figure 6 This is a schematic diagram of another base plate 110 provided in some embodiments of this application, wherein, Figure 6 The base plate 110 can be adapted Figure 7 Installation beam 120 in the middle Figure 8 The mounting beam 120 or other various mounting beams 120 that meet the requirements, therefore, Figure 6 The base plate 110 is not shown to show the specific structure for mounting the beam 120.

[0087] In this embodiment, the beam body 122 abuts against the outer wall surface 111.

[0088] Understandably, when the connecting part 121 is attached to and connected with the outer wall surface 111, the beam body 122 abuts against the outer wall surface 111, that is, the side surface of the connecting part 121 that is attached 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 base plate 110; optionally, a groove can be formed on the beam body 122, and the connecting part 121 can be fixedly disposed in the groove so that the surface of the beam body 122 and the surface of the connecting part 121 are flush; or, the connecting part 121 can be fixedly disposed on the surface of the beam body 122 that intersects with the outer wall surface 111, and the side surface of the connecting part 121 that is attached to the outer wall surface 111 is flush with the side surface of the beam body 122 facing the outer wall surface 111.

[0089] With this configuration, the connecting portion 121 of the mounting beam 120 can connect to and at least partially fit against the outer wall surface 111 of the base plate 110, while the beam body 122 can also abut against the outer wall surface 111. This effectively increases the contact area between the mounting beam 120 and the base plate 110. In other words, the mounting beam 120 can simultaneously disperse the force with the base plate 110 through the beam body 122 and the connecting portion 121, further reducing the risk of breakage between the mounting beam 120 and the base plate 110.

[0090] According to some embodiments of this application, please refer to Figures 2 to 5 The connecting part 121 is configured to be symmetrical about the central axis of the beam body 122.

[0091] Optionally, the connecting portion 121 may be symmetrically arranged about the central axis b of the beam body 122 along its length direction L; or, the connecting portion 121 may also be symmetrically arranged about the central axis c of the beam body 122 perpendicular to its length direction L; such as Figure 5 As shown, Figure 5 The connecting part is symmetrical about the central axis b of the beam body 122 along its length direction L, and also about the central axis c of the beam body 122 perpendicular to the length direction L.

[0092] With this configuration, the symmetrical distribution of the connecting part 121 about the beam body 122 makes the force transfer between the main body and the beam body 122 more even, so that the force distribution effect of the connecting part 121 on the base plate 110 is better, and the risk of breakage between the installed beam 120 and the base plate 110 is lower.

[0093] According to some embodiments of this application, please refer to Figures 2 to 5 The base plate 110 has a beam body 122 arranged along its central axis a.

[0094] Among them, the central axis a of the base plate 110 refers to the auxiliary line that can divide the base plate 110 into two relatively symmetrical parts; the beam body 122 is arranged along the central axis a of the base plate 110.

[0095] Understandably, when the main body of the electrical equipment vibrates, since the beam body 122 of the mounting beam 120 is fixedly connected to the main body, a certain degree of vibration will also occur between the connecting part 121 of the mounting beam 120 and the base plate 110, thereby generating stress between the connecting part 121 and the base plate 110.

[0096] With this configuration, when the main body vibrates, the box 10 also vibrates relative to the main body. The mounting beam 120 is connected to the main body, which is equivalent to the other parts of the box 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 base plate 110, that is, the mounting beam 120 is located at the amplitude center of the base plate 110. The connection part 121 of the mounting beam 120 is subjected to the force of the base plate 110 more evenly, thereby mitigating the risk of the mounting beam 120 breaking to a certain extent.

[0097] Optionally, the outer wall surface 111 of the base plate 110 can also be provided with mounting beams at both ends of the central axis a. The box 10 can be fixedly connected to the main body through the mounting beams so as to be used in conjunction with the mounting beam 120 for synchronous mounting.

[0098] According to some embodiments of this application, please refer to Figures 2 to 5 There are multiple connecting parts 121, and the multiple connecting parts 121 are arranged at intervals.

[0099] The multiple connecting parts 121 can be spaced apart in any direction; for example, the multiple connecting parts 121 can be arranged at intervals along the length direction L of the beam body 122; or, the multiple connecting parts 121 can also be arranged at intervals along the length direction L perpendicular to the beam body 122, for example, distributed on opposite sides of the beam body 122.

[0100] With this configuration, multiple spaced connecting parts 121 can be used to connect and fit with the base plate 110, and the force exerted on the base plate 110 can be dispersed through the multiple connecting parts 121, which can effectively reduce the risk of breakage between the connecting parts 121 and the base plate 110.

[0101] According to some embodiments of this application, please refer to Figure 6 , Figure 9 and Figure 10 The mounting beam 120 also includes a beam body 122. The portion of the beam body 122 facing the outer wall surface 111 forms a connecting portion 121, and the portion of the beam body 122 facing away from the outer wall surface 111 forms a mounting portion. The mounting portion is used to connect the main body. Along the thickness direction N of the base plate 110, the projection of the mounting portion is located within the projection of the connecting portion 121.

[0102] The portion of the beam body 122 facing the outer wall surface 111 forms a connecting portion 121, meaning the connecting portion 121 is 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 connecting portion 121 in the thickness direction N of the base plate 110. This increases the surface area on one side of the connecting portion 121, resulting in a larger contact area between the connecting portion 121 and the outer wall surface 111 of the base plate 110. The connecting portion 121 also provides better force dispersion on the base plate 110, thus reducing the risk of breakage between the mounting beam 120 and the base plate 110.

[0103] Optionally, the projection of the mounting part onto the thickness direction N of the base plate 110 within the projection of the connecting part 121 can be achieved by: setting the beam body 122 as a trapezoidal beam, i.e., the cross-section of the beam body 122 is trapezoidal, and then using the larger side of the two parallel side walls of the trapezoidal beam as the connecting part 121; or, setting the beam body 122 as a convex beam, i.e., the cross-section of the beam body 122 is approximately "convex", and then using the larger side of the outer wall of the convex beam as the connecting part 121; or, widening the beam body 122 as a whole to increase the surface area of ​​the outer wall of the beam body 122 used as the connecting part 121.

[0104] With this configuration, the projection of the mounting part is positioned within the projection of the connecting part 121 in the direction of the base plate 110. That is, the area of ​​the connecting part 121 is larger than the area of ​​the mounting part. By using the larger area of ​​the connecting part 121 to achieve connection and fit with the base plate 110, the force exerted by the base plate 110 on the connecting part 121 can be dispersed, thereby effectively reducing the risk of breakage between the connecting part 121 and the base plate 110.

[0105] According to some embodiments of this application, please refer to Figures 2 to 5The base plate 110 is provided with a flow channel 1101, which contains a heat exchange medium. Along the thickness direction N of the base plate 110, the projection of the flow channel 1101 and the projection of the connecting part 121 are separated from each other.

[0106] The flow channel 1101 is used to supply the flow of the heat exchange medium, so that the heat exchange medium can exchange heat with the structure (such as the battery cell 20) inside the housing 10 to achieve the purpose of cooling. Optionally, the heat exchange medium can be a liquid medium, such as cooling water or cooling oil.

[0107] Optionally, the flow channel 1101 can be formed using a blow-blown process, meaning the base plate 110 can be a blow-blown cold plate formed by the blow-blown process. Depending on the blow-blown cold plate manufacturing process, the mass of the blow-blown cold plate is relatively small; therefore, using a blow-blown cold plate as the base plate 110 can reduce the overall weight of the housing 10.

[0108] Understandably, the base plate 110 can also be a brazed cold-rolled plate formed by a stamping process, specifically as follows: Figure 6 As shown; Figure 6 The base plate 110 shown does not include the flow channel 1101, thereby allowing the base plate 110 to accommodate the mounting beam 120 with a larger surface area of ​​the connection portion 121; optionally, Figure 6 The base plate 110 in the middle can be, but is not limited to, applicable to Figure 5 , Figure 7 , Figure 9 , Figure 10 Mounting beam 120 or other mounting beam 120 structures.

[0109] This configuration allows the flow channel 1101 and the connecting part 121 to be separated in the thickness direction of the base plate 110, reducing the force between the connecting part 121 and the base plate 110 that could damage the flow channel 1101.

[0110] For example, in some specific embodiments, the housing 10 includes a base plate 110 and a mounting beam 120. The base plate 110 is preferably a blown cold plate, and flow channels 1101 are formed on the base plate 110 by a blown process. The mounting beam 120 includes a beam body 122 and a connecting portion 121. The connecting portion 121 is finned. The beam body 122 has multiple fins integrally formed on the side facing the base plate 110. The multiple fins are spaced apart along the length direction L of the beam body 122. The fins can be rectangular fins, and the fins extend out of the beam body 122 in a direction parallel to the outer wall surface 111 and perpendicular to the length direction L of the beam body 122. During assembly, the beam body 122 is placed along the base plate 110. The central axis a of 10 is arranged, and each fin is attached to the outer wall surface 111 of the base plate 110 and spot welded to form an integral unit. The connection between the fin and the outer wall surface 111 must avoid the flow channel 1101 formed on the base plate 110. For example, the fin can be attached to the gap between the flow channels 1101, or the area on the outer periphery of the flow channel 1101. At this time, a gap is formed between the beam body 122 and the outer wall surface 111, so that the beam body 122 can avoid the flow channel 1101. The connection between the fin and the base plate 110 can disperse the stress between the base plate 110 and the mounting beam 120, which can effectively reduce the risk of fracture between the base plate 110 and the mounting beam 120.

[0111] According to some embodiments of this application, please refer to Figure 2 Secondly, this application embodiment also provides a battery 100, including a battery cell 20 and a housing 10 as described above, with the battery cell 20 located inside the housing 10. The battery 100 provided in this application embodiment, including the aforementioned housing 10, results in a more robust overall structure for the battery 100, given a lower risk of breakage between the mounting beam 120 and the base plate 110 of the housing 10.

[0112] According to some embodiments of this application, please refer to Figure 1 Thirdly, this application also provides an electrical device, including a main body and a battery 100 as described above. The housing 10 of the battery 100 is disposed on the main body, and the battery 100 is used to provide electrical energy. The electrical device can be any of the electrical devices described in the above embodiments, such as a vehicle 1000, which will not be elaborated further here.

[0113] The electrical device provided in this application embodiment includes the battery 100 described above. With a more stable overall structure of the battery 100, the process of the battery 100 being mounted on the main body and providing power to the main body is more stable, and the risk of the battery 100 falling off the main body is lower.

[0114] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this application should be included within the protection scope of this application.
