Description

[Technical Field]

[0001] FIELD OF THE INVENTION This application relates to the field of battery technology, and more particularly to housings, batteries and power consuming devices. [Background technology]

[0002] As new energy technologies become more and more mature, new energy vehicles are gradually coming into the public's sights. The main core technology of new energy vehicles is the battery, and the safety and stability of the battery directly determine the performance of the finished vehicle.

[0003] A vehicle generally includes a vehicle body and a battery mounted on the vehicle body, and the battery generally includes a housing and battery cells mounted within the housing. When the housing is mounted on the vehicle body, the connection rigidity between the two tends to become relatively poor. Summary of the Invention

[0004] In view of this, the present application chassis The present invention is intended to provide a battery and a power consumption device, and to improve the connection rigidity between the housing and the vehicle.

[0005] According to a first aspect, the present application provides a housing, the housing having an accommodating cavity for accommodating a battery cell and a top surface facing the accommodating cavity, a first area and a second area formed on the top surface of the housing, the second area surrounding the first area, a plurality of hook portions configured in the second area, and the battery being attached to an external device via the hook portions, wherein the distance between the geometric centers of orthogonal projections of each two adjacent hook portions in the second area is 80 mm-500 mm.

[0006] In this way, the solution of the present application ensures that the distance between the geometric centers of adjacent hanging parts is within a limited range, ensures that the installation distance between hanging parts is controllable, and by controlling the installation distance between hanging parts, ensures that the multiple hanging positions on the housing are basically distributed evenly, makes the force-bearing capacity of the car body uniform, and further improves the connection rigidity between the car body and the housing at each position.

[0007] In some embodiments, the distance between the geometric centers of the orthogonal projections of each two adjacent latching portions in the second region is 80 mm-300 mm, i.e., within the range of 80 mm-300 mm, which can ensure the uniformity of the connection between the battery and the external device and at the same time ensure the strength of the connection between the battery and the external device.

[0008] In some embodiments, a sealing area is further formed on the top surface of the housing, the sealing area being between the first area and the second area and surrounding the first area, the sealing area being used to attach a sealant, and the sealant being used to contact an external device to realize a sealed connection between the vehicle body and the housing.

[0009] In some embodiments, the sealing area is on the same plane as the second area, and at this time, the latching force receiving points of each latching part and the sealing area are located on the same plane and at the same height, and the latching force receiving points and the sealing material only bear vertical force, thereby reducing the force received by the housing and the side structure of the vehicle body and improving the rigidity of the vehicle.

[0010] In some embodiments, the first area, the second area, and the sealing area are on the same plane, and the plane on which the first area, the second area, and the sealing area are on the same plane contacts the external device, and the contact area between the top surface of the housing and the external device is relatively large, which contributes to improving the connection reliability between the housing and the external device, and at the same time, the top structure of the housing is relatively flat and more aesthetically pleasing, and further reduces the force received by the side structure of the housing.

[0011] In some embodiments, the latching portion includes at least one latching hole provided in the top of the housing, the latching hole penetrating the second region, and when the connecting member connects the housing to the external device, the connecting member can connect to the top of the housing from the second region that is relatively outer circumferential from the top of the housing, thereby improving the connection strength between the housing and the external device.

[0012] In some embodiments, the housing further includes a sealant attached to the sealing region, where the battery housing achieves a sealed connection with an external device through the sealant, seals the first region and the second region, and provides a reliable seal at a relatively low cost.

[0013] In some embodiments, the housing includes a body that surrounds and forms the receiving cavity, a top surface of the body defining and forming at least a portion of the top surface of the housing, and the first region and the sealing region are located on the top surface of the body.

[0014] The top surface of the body is divided into a first region and a sealing region surrounding the first region, and the first region forms a sealed interior of the body, thereby realizing a sealed connection between the body and the body.

[0015] In some embodiments, the housing includes side beams, the main body has a peripheral side wall surrounding the outer edge of the top of the main body, the side beams are provided on the peripheral side wall, and the top surface of the main body and the top surface of the side beams together define and form the top surface of the housing. The side beams are provided on the side peripheral walls of the main body, which can reinforce the lateral structural strength of the main body and further improve the lateral crushing ability of the housing, and at the same time improve the lateral crushing ability of the vehicle.

[0016] In some embodiments, the latch is located in the second region defined by the top surface of the side beam. Since the latch is located on the side beam and the side beam does not need to define the receiving cavity, the installation of the latch does not need to be considered regarding the effect of the latch on the sealing of the receiving cavity, making the installation of the latch more flexible. Furthermore, since the side beam is located on the side edge of the housing, the latch is located on the side beam, and the operation space is larger and easier when attaching the housing to an external device.

[0017] In some embodiments, the side beam includes at least two first sub-beams and at least two second sub-beams, both of which are provided on the circumferential side wall, the first sub-beams extending along a first direction and spaced apart from each other, the second sub-beams extending along a second direction intersecting the first direction and spaced apart from each other, the hook portions are provided on the first sub-beams and / or the second sub-beams, and the distance between the geometric centers of the orthogonal projections of each two adjacent hook portions in the second region in the first direction and / or the second direction is 80 mm-500 mm.

[0018] A hook portion is provided on each of the first sub-beam and / or the second sub-beam, and by extending the hook portion along the first direction and / or the second direction, uniform hooking and fixing with an external device is achieved in multiple directions.

[0019] In some embodiments, the body includes a support member and a frame, the frame surrounding and forming a cavity through which at least a top end of the frame is disposed, the support member overlies the top end of the cavity, the support member and frame surrounding and forming at least a portion of the receiving cavity, and the lateral beams disposed on circumferential sidewalls defined by the frame.

[0022] In some embodiments, the housing includes a main body that surrounds and forms a storage cavity, the main body includes a support member located at the top of the housing to define the storage cavity, and the battery cells are installed on the support member. The battery cells are installed below the support member and, together with the support member, bear the force of the top of the battery housing, thereby improving the rigidity of the top of the battery housing.

[0023] In some embodiments, , electricThe battery cells are suspended below the support member, and the bottom cover is located at the bottom of the housing, so that when performing maintenance on the inside of the battery, the battery cells can be exposed by removing the bottom cover, eliminating the need to remove the support member, making battery maintenance easier. At the same time, when performing battery maintenance, the battery cells can be attached and detached to and from the support member from below, making it easier to maintain the battery, especially when the support member is subjected to force as at least part of the vehicle chassis, because the battery cells can be attached and detached only from below the support member, eliminating the need to remove the support member.

[0024] In some embodiments, the battery cells are bonded to the support members. , contact This not only makes it easier to connect the battery but also simplifies the structure of the battery.

[0025] In some embodiments, the outer surface of the battery cell facing the support member is a first outer surface, and the battery cell includes electrode terminals, which are located on an outer surface of the battery cell other than the first outer surface. In this case, the electrode terminals are located on an outer surface of the battery cell other than the first outer surface, and various components connecting the electrode terminals (e.g., sampling harnesses, high-voltage harnesses, protective structures, etc.) can be arranged in the space between the battery cell and the bottom cover and / or the space between the battery cell and the inner surface of the main body, making the arrangement of the components easier. In addition, by connecting the first outer surface, on which the electrode terminals are not located, to the support member, the battery cell and the support member can be bonded together, saving space between the battery cell and the support member and improving the space utilization rate of the battery.

[0026] In some embodiments, the battery cell has a second outer surface that is disposed back-to-back with the first outer surface, and the electrode terminals are disposed on the second outer surface. A buffer space is provided between the second outer surface and the bottom cover, and the electrode terminals extend from the battery cell and are located within the buffer space. Thus, a wiring harness and a connection sheet connected to the electrode terminals can be disposed within the buffer space. At the same time, the buffer space can also prevent external force striking the bottom cover from acting on the battery cell and damaging it. Therefore, the buffer space not only shields the battery cell from the effects of external force, but also allows for the layout of the wiring harness and other components, achieving two-for-one benefits.

[0027] According to a third aspect, the present application further provides a power consuming device, the power consuming device comprising the battery described above, the battery being used to provide electrical energy to the power consuming device.

[0028] In some embodiments, the power consumption device includes a vehicle, and the battery is located at the bottom of the vehicle, so that the battery does not occupy space inside the vehicle, thereby contributing to reducing the volume and weight of the vehicle.

[0029] In some embodiments, the battery is connected to the vehicle body through the top of the housing, and the top of the housing is configured to form at least a part of the chassis of the vehicle body, so that the space occupied by the gap between the conventional chassis and the battery can be divided into the battery, thereby improving the battery space, thus contributing to improving the energy of the battery and further improving the driving range of the vehicle.

[0041] Currently, from the viewpoint of market development trends, the application of batteries is becoming more and more widespread. Batteries are not only applied to energy storage power systems such as hydroelectric power, thermal power, wind power and solar power plants, but also widely used in electric transportation such as electric bicycles, electric motorcycles and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery application fields, the market demand is also constantly expanding.

[0042] The inventors have noticed that when connecting a battery housing to a vehicle body, a fixing structure is generally installed to fix the housing to the vehicle body, but the fixing points of the fixing structure to the housing and the vehicle body are not uniform, which results in uneven force reception between the vehicle body and the housing, resulting in relatively poor connection rigidity.

[0043] In order to improve the connection rigidity between the housing and the vehicle body, the applicant's research has found that the fixing action points of the fixing structure on the housing and the vehicle body can be rationally arranged, the fixing structure can be evenly distributed on the housing and the vehicle body, the force bearing by the vehicle body and the housing can be uniform, and the fixing action will not be too strong or fixed at any particular position, thereby improving the connection rigidity between the vehicle body and the housing at each position.

[0044] Based on the above considerations, the inventors conducted extensive research to design a battery housing capable of accommodating battery cells. The housing has a top surface facing a cavity, the top surface being divided into a first region and a second region. The second region surrounds the first region, and the second region is provided with a plurality of latches. The battery is attached to an external device via the latches, and the distance between the geometric centers of the orthogonal projections of each adjacent latch in the second region is 80 mm to 500 mm. By controlling the distance between the latches, the multiple latching positions on the housing are essentially evenly distributed, which evens out the force received by the vehicle body and further improves the connection rigidity between the housing and the vehicle body at each position.

[0045] The battery disclosed in the embodiments of the present application can be used in, but is not limited to, power consumption devices such as vehicles, ships, and aircraft. The battery disclosed in the present application can be used to configure a power supply system for the power consumption device. The mounting structure of the present application is a structure for mounting a battery in a power consumption device.

[0046] An embodiment of the present application provides a power-consuming device that uses a battery as a power source, and the power-consuming device may be, but is not limited to, a mobile phone, a tablet, a laptop, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a steamship, a spacecraft, etc. Here, the electric toy may include a stationary or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric plane toy, and the spacecraft may include an airplane, a rocket, a spacecraft, a spaceship, etc.

In this way, the end cap 21 is less likely to deform when extruded or impacted, and the battery cell 20 may have higher structural strength and improved safety. Functional members such as electrode terminals 21a may be installed on the end cap 21. The electrode terminals 21a may be used to electrically connect to the electrode assembly 23 for inputting or outputting electrical energy to or from the battery cell 20.

Illustratively, the insulating member may be plastic, rubber, or the like.

[0052] The case 22 is an assembly that fits onto the end cap 21 to form an internal environment of the battery cell 20. The formed internal environment may be used to accommodate the electrode assembly 23, electrolyte, and other components. The case 22 and the end cap 21 may be separate components, or an opening may be formed on the case 22, and the end cap 21 may be placed over the opening to form the internal environment of the battery cell 20. The end cap 21 and the case 22 may be integrated. Specifically, the end cap 21 and the case 22 may first form a common connection surface before other components are inserted into the case. When the interior of the case 22 needs to be packaged, the case 22 is placed over the end cap 21. The case 22 may have various shapes and sizes, such as a rectangular parallelepiped, cylindrical, or hexagonal prism. Specifically, the shape of the case 22 may be determined depending on the specific shape and size of the electrode assembly 23. The case 22 may be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and the embodiments of the present application do not impose any particular limitations thereon.

[0053] The electrode assembly 23 is a component that generates an electrochemical reaction within the battery cell 20. One or more electrode assemblies 23 may be contained within the case 22. The electrode assembly 23 is mainly formed by winding or stacking a positive electrode plate and a negative electrode plate, and a separator is generally provided between the positive electrode plate and the negative electrode plate. The portions of the positive electrode plate and the negative electrode plate that have active material constitute the main body 11 of the electrode assembly 23. accomplish The positive and negative electrode tabs may both be located at one end of the body 11, or may each be located at both ends of the body 11.

[0062] In this case, the battery 100 is attached to the external device through the top of the housing 10, and the connection structure between the housing 10 and the external device is smaller in size, less expensive and more compact than an arrangement in which the housing 10 is located at the bottom of the external device.

[0063] Of course, in other embodiments, the battery 100 may be attached to an external device via the bottom, side, or other location of the housing 10 .

[0064] In some embodiments, referring to FIG. 4, the housing 10 includes a body 11 that surrounds and forms a receiving cavity s.

[0065] The main body 11 may be a single-piece structure or may be formed by assembling multiple parts. As can be understood, the main body 11 is a hollow shell-like structure that surrounds itself to form the storage cavity s. Without being limited to a specific example, the main body 11 may be formed by assembling a first sub-part (not shown) and a second sub-part (not shown). In one example, the first sub-part surrounds and forms the storage cavity s with an open end, and the second sub-part covers the open portion of the storage cavity s. In another example, the first sub-part surrounds and forms a first space with an open end, and the second sub-part surrounds and forms a second space with an open end, and the two open portions of the first sub-part and the second sub-part cover each other to form the storage cavity s consisting of the first space and the second space. The first sub-part and the second sub-part may be welded, fastened, or otherwise connected. The first sub-part and the second sub-part may be made of plastic, metal, or other materials.

[0066] In some embodiments, referring to FIG. 4, the top of body 11 forms at least a portion of the top of housing 10.

[0067] The top of the main body 11 refers to a structure located at the top position of the main body 11 in the vertical direction, and the top position of the main body 11 is the top position of the housing 10, whereby the top of the main body 11 forms at least a part of the top of the housing 10. When the top of the main body 11 forms the entire top of the housing 10, the top of the main body 11 is the top of the housing 10, and the entire top of the housing 10 participates in defining the storage cavity s. When the top of the main body 11 forms a part of the top of the housing 10, the top of the housing 10 further has a structure whose other parts do not participate in defining the storage cavity s, such as the lateral beams 13 described below, which will be specifically described in detail below.

[0068] When the battery 100 is attached to an external device via the top of the housing 10, the top of the main body 11 is also at the position closest to the external device on the battery 100, and the distance between the top of the main body 11 and the external device is the distance in the vertical direction between the highest point of the top of the main body 11 and the external device located above it.

[0069] As can be seen, with reference to Figure 6, the body 11 has a circumferential sidewall n disposed around the top outer edge of the body 11.

[0070] The main body 11 has a top portion located at the uppermost position in the vertical direction, and of course a bottom portion located at the lowermost position, where the bottom portion may be a structure installed on the bottom surface or may be a bottom opening.

[0071] The outer surface facing the receiving cavity s sandwiched between the top and bottom forms a circumferential sidewall n, and the extension direction of the plane on which the circumferential sidewall n is located intersects with the plane on which the top is located. The circumferential sidewall n may be annular, rectangular, or other shapes formed by joining the ends of multiple walls, as will be described in detail below.

[0072] As can be seen, with reference to FIG. 6, the housing 10 further has a top surface h facing the receiving cavity s.

[0073] The top surface h of the housing 10 is located on one surface facing away from the receiving cavity s at the top of the housing 10, and when the battery 100 is assembled to an external device via the top of the housing 10, the top surface h is positioned facing the external device and forms the position of the battery 100 closest to the external device.

[0074] In some embodiments, referring to FIG. 6, the top surface h of the housing 10 is configured to contact an external device (not shown) to which the battery 100 is attached.

[0075] The battery 100 is attached to the external device through the top of the housing 10, and one surface of the housing 10 facing the receiving cavity s is in contact with and attached to the external device, so that the battery 100 is tightly connected to the external device. In this arrangement, the top surface h of the housing 10 does not contact the external device, and the connection structure between the housing 10 and the external device is smaller in size, relatively low in cost, and more compact.

[0076] In some embodiments, referring to FIG. 6, a hook portion 13a3 is formed on the top of the housing 10, and the battery 100 is attached to an external device via the hook portion 13a3.

[0077] The hook portion 13a3 is not involved in defining the storage cavity s as part of the top of the housing 10. The hook portion 13a3 is a dedicated structure for connecting to a connecting member (e.g., a bolt, a rivet, etc.) of an external device installed on the top of the housing 10, one end of the connecting member being connected to the hook portion 13a3 and the other end being connected to the external device to fixedly connect the battery 100 to the external device. As can be understood, the top of the main body 11 is at least a part of the top of the housing 10, and the hook portion 13a3 may be installed on the top of the main body 11 or on another structure that constitutes and forms the top of the housing 10 (the top of the side beam 13 mentioned below).

[0078] The hook portion 13a3 is not involved in defining the storage cavity s as part of the top of the housing 10. The hook portion 13a3 is a dedicated structure for connecting to a connecting member (e.g., a bolt, a rivet, etc.) of an external device installed on the top of the housing 10, one end of the connecting member being connected to the hook portion 13a3 and the other end being connected to the external device to fixedly connect the battery 100 to the external device. As can be understood, the top of the main body 11 is at least a part of the top of the housing 10, and the hook portion 13a3 may be installed on the top of the main body 11 or on another structure that constitutes and forms the top of the housing 10 (the top of the side beam 13 mentioned below).

[0079] When the battery 100 is attached to an external device via the latch portion 13a3, the top surface h of the housing 10 comes into contact with and connects to the external device, improving the connection strength while also ensuring the compactness of the connection structure between the housing 10 and the external device.

[0080] The hook 13a3 itself may have a connecting function (such as a lifting ring), and a corresponding connecting member (such as a hook) may be installed on an external device to directly connect the hook 13a3. In other embodiments, no connecting member may be installed, and the hook 13a3 may be directly connected to the external device by other methods, including, but not limited to, fastening, insertion, screw connection, riveting, welding, adhesive, etc., and the present application does not specifically limit the present invention.

[0081] In some embodiments, referring to FIG. 6, the latch portion 13a3 includes at least one latch hole k1 provided on the top of the housing 10.

[0082] The hanging holes k1 may be formed on the top of the housing 10 by drilling, and each of the hanging holes k1 has an opening communicating with a hole and both ends of the hole inside, and the opening communicating with both ends of the hole allows the connecting member to pass through it and be fixed to the structure on which the hanging holes k1 are provided, thereby realizing the connection between the external device and the top of the housing 10 by the connecting member.

[0083] The connecting member may be a rivet, with a fixing hole 11c3 provided at a position corresponding to the hanging hole k1 of the external device, and the rivet passing through the fixing hole 11c3 and the hanging hole k1, and then fastening them together with a nut. The connecting member may be a screw, with the hanging hole k1 set as a threaded hole, and a screw passing through the hanging hole k1 and threadedly connected to the housing 10.

[0084] Specifically, all of the latching holes k1 may extend vertically to fix the battery 100 to the bottom of the external device vertically. As can be understood, in order to achieve stable connection between the top of the housing 10 and the external device and uniform force reception between them, factors such as the installation position and installation distance of all of the latching holes k1 may be controlled, as will be described in detail below.

[0085] As can be understood, the hook portion 13a3 may include other structures capable of achieving hooking, such as hooks, in addition to including the hook hole k1.

[0086] In some embodiments, referring to Figures 4 and 6, the main body 11 includes a support member 11a and a frame 11b, the frame 11b surrounding the cavity through which at least the top end is installed, the support member 11a covering the top end of the cavity, and the support member 11a and the frame 11b surrounding the cavity to form at least a portion of the receiving cavity s.

[0087] The frame 11b itself surrounds and forms a cavity through which at least the top end is installed, and the support member 11a covers the top of the cavity; that is, the support member 11a is located at the top of the housing 10 and is used to define the storage cavity s. The frame 11b and the support member 11a may be made of the same material, such as an aluminum alloy, copper alloy, steel, or plastic. Of course, the frame 11b, the support member 11a, and the bottom cover 11c may be made of different materials, and there is no specific limitation. When projected orthogonally in the vertical direction, the frame 11b may have a rectangular, circular, polygonal, or other shape, and there is no specific limitation. The support member 11a may be a support plate, support sheet, support block, or other structure.

[0088] The top surface h1 of the main body 11 may be entirely formed by the top surface of the support member 11a, in which case the entire frame 11b is located below the support member 11a. The top surface h1 of the main body 11 may be entirely formed by the top surface of the support member 11a and the top surface of the frame 11b, in which case the support member 11a is located inside the frame 11b, and the top surfaces of the support member 11a and the frame 11b may or may not be on the same plane.

[0089] The support member 11a is fixedly connected to the frame 11b or is integrally formed with the frame 11b. The support member 11a and the frame 11b are integrally formed using a method such as injection molding, die casting, forging, cold pressing, hot pressing, etc. The support member 11a and the frame 11b may be fixedly connected with each other by fastening with fasteners, engagement with an engaging structure, welding, adhesive, hot melt connection, etc.

[0090] The circumferential side wall n of the main body 11 is mainly formed by the circumferential side wall n of the frame 11b, which is an outer surface that is installed around the support member 11a and is away from the cavity defined by it.

[0091] In some embodiments, referring to FIGS. 4 and 5, the main body 11 further includes a bottom cover 11c, which, together with the support member 11a and the frame 11b, forms a housing cavity s that houses the battery cell 20.

[0092] As can be seen, the cavity in the frame 11b further penetrates the bottom of the frame 11b, and the bottom cover 11c covers the bottom of the frame 11b and forms the receiving cavity s of the housing 10 together with the frame 11b and the support member 11a.

[0093] Specifically, the bottom cover 11c may have a plate-like structure, a block-like structure, or the like, but is not limited thereto, and may also have a flat plate-like, curved plate-like, or the like, without being specifically limited thereto. When the battery cell 20 is located in the accommodating cavity s, the battery cell 20 may be installed on the bottom cover 11c and / or the support member 11a and / or the frame 11b.

[0094] The bottom cover 11c and the frame 11b can be secured to each other by welding, hot melt connection, adhesive bonding, fastening, interlocking, etc. Here, "fastening" refers to a connection achieved using fasteners 11c4, which include bolts, plugs, rivets, pins, screws, etc. Here, "interlocking" refers to a fastening achieved using an engaging structure, such as a hook on the bottom cover 11c and an engaging opening on the frame 11b, where the hook engages with the engaging opening to secure the bottom cover 11c to the frame 11b. Of course, the connection methods between the bottom cover 11c and the frame 11b are not limited to these and are not covered in this application.

[0095] In this case, the frame 11b is used as a base, and the support member 11a and the bottom cover 11c are connected to both ends of the frame 11b in the vertical direction, respectively, and then the cavity s for accommodating the battery 100 can be formed, so the structure of the main body 11 is relatively simple.

[0096] In some embodiments, referring to Figures 4 and 5, the bottom cover 11c has a cover portion 11c1 and a mounting portion 11c2, the mounting portion 11c2 is connected to the edge of the cover portion 11c1 in a surrounding manner, the cover portion 11c1 is used to define the storage cavity s, and the mounting portion 11c2 is connected to the frame 11b.

[0097] The term "lid portion 11c1 is used to define the receiving cavity s" refers to the fact that the lid portion 11c1, the support member 11a, and the frame 11b together enclose the receiving cavity s, while the mounting portion 11c2 is connected to the frame 11b and is not involved in defining the receiving cavity s. The lid portion 11c1 may be a plate-like, block-like member, or a flat, curved plate-like member, and is not specifically limited. As can be seen from FIGS. 4 and 5 , the term "the mounting portion 11c2 is surrounded by the edge of the lid portion 11c1" refers to the fact that the mounting portion 11c2 is continuously installed along the edge of the lid portion 11c1, forming a structure in which the ends are hermetically connected. As can be seen, in vertical projection, the mounting portion 11c2 has a certain width, which allows for an appropriate contact area with the frame 11b, thereby facilitating positioning and attachment between the mounting portion 11c2 and the frame 11b.

[0098] The lid portion 11c1 and the mounting portion 11c2 may be integrally molded. If the bottom lid 11c is made of a metal material (e.g., aluminum, iron, stainless steel, etc.), the lid portion 11c1 and the mounting portion 11c2 may be integrally molded using methods such as die casting, forging, hot pressing, and cold pressing. If the bottom lid 11c is made of a plastic material (e.g., polypropylene, polyethylene, ABS (Acrylonitrile Butadiene Styrene plastic), etc.), the lid portion 11c1 and the mounting portion 11c2 may be integrally molded by injection molding. The lid portion 11c1 and the mounting portion 11c2 may be molded separately and then connected together. If the lid portion 11c1 and the mounting portion 11c2 are made of a metal material, the lid portion 11c1 and the mounting portion 11c2 may be welded or bonded together. If the lid portion 11c1 and the mounting portion 11c2 are made of a plastic material, the lid portion 11c1 and the mounting portion 11c2 may be bonded together. Of course, the cover portion 11c1 and the attachment portion 11c2 may be fixedly connected together by other methods such as fastening or riveting.

[0099] The cover portion 11c1 and the mounting portion 11c2 may be located in the same plane. Specifically, the cover portion 11c1 and the mounting portion 11c2 may have two surfaces facing the support member 11a located in the same plane, and / or the cover portion 11c1 and the mounting portion 11c2 may have two surfaces facing away from the support member 11a located in the same plane. When the cover portion 11c1 and the mounting portion 11c2 have two surfaces facing the support member 11a and two surfaces facing away from the support member 11a located in the same plane, respectively, the cover portion 11c1 and the mounting portion 11c2 may form a flat bottom cover 11c.

[0100] The lid portion 11c1 and the mounting portion 11c2 do not have to be located on the same plane. Specifically, the lid portion 11c1 may be recessed toward the support member 11a relative to the mounting portion 11c2, or the lid portion 11c1 may protrude away from the support member 11a relative to the mounting portion 11c2, but this is not specifically limited. The thicknesses of the lid portion 11c1 and the mounting portion 11c2 may or may not be equal, and this is not specifically limited.

[0101] In this case, the bottom cover 11c defines the receiving cavity s via the cover portion 11c1, and is connected to the frame 11b via the attachment portion 11c2, resulting in a clear structure and easy attachment.

[0102] As can be understood, when the bottom cover 11c is detachably connected to the frame 11b, the bottom cover 11c is detachably connected to the frame 11b via the mounting portion 11c2, i.e., the mounting portion 11c2 is detachably connected to the frame 11b. The method of detachably connecting the mounting portion 11c2 to the frame 11b can be achieved by setting the portion of the bottom cover 11c that is detachably connected to the frame 11b as the mounting portion 11c2.

[0103] In some embodiments, the mounting portion 11c2 is removably connected to the frame 11b.

[0104] Specifically, the bottom cover 11c further includes a fixing hole 11c3 disposed on the mounting portion 11c2, and the fastener 11c4 is drilled through the fixing hole 11c3 on the mounting portion 11c2 and then fastened to the frame 11b. The fixing hole 11c3 is a through-hole that passes through the mounting portion 11c2 in the vertical direction. Specifically, the fixing hole 11c3 may be a smooth through-hole (e.g., when the fastener 11c4 is a rivet), a threaded through-hole (e.g., when the fastener 11c4 is a screw), or another type of through-hole (e.g., a hexagonal hole, a square hole, an elongated hole, etc.). The specific type of the fixing hole 11c3 is determined based on the specific type and specific setting method of the fastener 11c4 and will not be further described here.

[0105] In some embodiments, referring to FIGS. 6, 8 and 9, the housing 10 includes lateral beams 13, which are provided on the circumferential sidewalls n of the body 11.

[0106] The side beams 13 refer to beam structures installed on the circumferential side walls n of the main body 11 to reinforce the strength of the main body 11. As can be understood, the side beams 13 are located outside the main body 11. Specifically, the main body 11 and the side beams 13 may be integrally connected or connected together in an assembled manner. The integral connection method includes, but is not limited to, welding, integral molding, welding, etc. The assembled connection method includes, but is not limited to, fastening, clamping, etc.

[0107] The side beams 13 may be arranged on all of the circumferential side walls n of the main body 11, or may be arranged only locally on the circumferential side walls n of the main body 11. Without being limited thereto, the side beams 13 may be arranged surrounding the circumferential side walls n of the main body 11, thus reinforcing the strength of the main body 11 from multiple sides of the main body 11. Specifically, the side beams 13 may be arranged continuously or intermittently surrounding the circumferential side walls n of the main body 11. When arranged continuously, the side beams 13 may take the form of an annular beam, and when arranged intermittently, the side beams 13 may include multiple beam portions arranged at intervals surrounding the circumferential side walls n of the main body 11.

[0108] In an actual application scenario, the housing 10 is used with the battery 100, and the battery 100 is applied to a vehicle 1000. The top of the housing 10 is attached to the vehicle 1000, and the top of the housing 10 forms the chassis structure of the vehicle 1000. When the housing 10 of the battery 100 is used as the chassis of the vehicle 1000, the side structure of the housing 10 is susceptible to being pressed by external impacts (for example, a stone flying while the vehicle 1000 is moving strikes the side of the housing 10, or the side is struck by another vehicle 1000). In this case, side beams 13 are installed on the side peripheral walls of the main body 11, and the side structural strength of the main body 11 can be reinforced by the side beams 13, further improving the side pressure resistance of the housing 10 and, at the same time, improving the side pressure resistance of the vehicle 1000, thereby improving the safety of the vehicle 1000.

[0109] As can be seen, when the body 11 includes the support members 11a and the frame 11b, the lateral beams 13 are mounted on the circumferential sidewalls n defined by the frame 11b.

[0110] The cavity formed by the frame 11b mainly constitutes the receiving cavity s of the housing 10, and since the receiving cavity s has a certain height to accommodate multiple battery cells 20, the frame 11b also has a certain height, and therefore the area of ​​the circumferential side wall n of the frame 11b is relatively large. In this case, the side beams 13 are provided on the circumferential side wall n defined by the frame 11b, and the mounting method, mounting area, and arrangement method of the side beams 13 are more flexible.

[0111] In a further embodiment, the side beams 13 are fixedly connected to the frame 11b or are integrally formed with the frame 11b. The fixed connection between the side beams 13 and the frame 11b may be realized by welding, riveting, screw connection, etc., or may be integrally formed by integral processing (e.g., pressing, die casting).

[0112] If the side beams 13 are integrally molded with the frame 11b, it is possible to reduce the assembly process of the housing 10 and accelerate the production process of the housing 10. If the side beams 13 are fixedly connected to the frame 11b, the molding process of the side beams 13 and the frame 11b is relatively easy, and it is possible to reduce the process cost of the housing 10.

[0113] 10, in some embodiments, the side beam 13 includes at least two sub-beams 13a that are spaced apart in sequence along the circumferential side wall n. The sub-beams 13a are basic units that make up the side beam 13, and the position of the side beam 13 on the circumferential side wall n of the main body 11 can be flexibly arranged by setting the position of the sub-beams 13a.

[0114] The side beam 13 is formed by at least two sub-beams 13a spaced apart along the circumferential side wall n of the main body 11, which means that at least two sub-beams 13a are spaced apart along the extension direction of the circumferential side wall n to form a shape that surrounds the main body 11, thereby reinforcing the strength of the main body 11 from multiple sides of the main body 11.

[0115] The sub-beams 13a may have various structures, and the structures of the sub-beams 13a may be the same or different. For example, the sub-beams 13a are solid beams extending in one longitudinal direction. For example, the sub-beams 13a are hollow beams extending in one longitudinal direction. The cross-sectional shape of each sub-beam 13a may be H-shaped, U-shaped, or the like.

[0116] In this case, the side beam 13 is formed by combining multiple sub-beams 13a, and the arrangement of the side beam 13 is more flexible. When installing at the same time, each sub-beam 13a only needs to be installed one by one. Compared with the one-piece side beam 13, the positioning in the installation process is easier and more labor-saving.

[0117] In some embodiments, still referring to FIG. 10, at least one sub-beam 13a includes an upper arm beam 131 and a lower arm beam 132, which are spaced apart vertically and both connected to the main body 11.

[0118] The up-down direction corresponds to the direction in which the top and bottom of the main body 11 are located, i.e., the upper arm beam 131 is close to the top of the main body 11, and the lower arm beam 132 is close to the bottom of the main body 11. As can be understood, the upper arm beam 131 and the lower arm beam 132 both extend along the circumferential direction of the main body 11 and are attached to the circumferential side wall n of the main body 11. The upper arm beam 131 and the lower arm beam 132 are spaced apart, and are connected by the main body 11. A hole can be formed in the middle of the space between them, and this hole can be a structure for reducing weight or for routing a wire harness.

[0119] At this time, the upper arm beam 131 and the lower arm beam 132 reinforce the structure of the main body 11, and because the upper arm beam 131 and the lower arm beam 132 are arranged separately, the impact force received by the housing 10 can be dispersed, and the external force received by each part of the housing 10 is relatively uniform. At the same time, the upper arm beam 131 and the lower arm beam 132 are arranged at a distance from each other in the vertical direction, so that the sub-beam 13a can withstand pressure in the front-rear or left-right direction of the vehicle 1000, and is more adapted to the actual usage conditions of the vehicle 1000. In addition, the method in which the upper arm beam 131 and the lower arm beam 132 are arranged at a distance from each other reduces the weight of the housing 10 and can achieve other functions.

[0120] In other embodiments, an intermediate beam (not shown) may be further installed between the upper arm beam 131 and the lower arm beam 132, and the intermediate beam may be connected between the upper arm beam 131 and the lower arm beam 132, thus further reinforcing the structural strength of the sub-beam 13a and improving the lateral pressure resistance of the housing 10.

[0121] In some embodiments, at least one of the upper arm beam 131 and the lower arm beam 132 is a hollow beam. A hollow beam is a beam with a hollow structure inside, that is, a space that is not filled with any solid material. In this case, the upper arm beam 131 and the lower arm beam 132 have a hollow beam structure, which not only reduces the weight of the battery itself, but also alleviates the problem of high energy consumption due to the heavy weight of the battery 100 when the battery 100 formed by the housing 10 is applied to a power-consuming device such as a vehicle 1000. Furthermore, the hollow beam structure allows the internal space to absorb lateral pressure, reducing the degree of damage to the battery 100 when subjected to lateral pressure.

[0122] In some embodiments, referring to FIG. 6, the circumferential side wall n includes at least two first wall portions n1, both extending along the first direction F1 and spaced apart, and the at least two sub-beams 13a include two first sub-beams 13a1, each of which is disposed on one of the two first wall portions n1 and both extending along the first direction F1.

[0123] In one practical application, when the battery 100 formed by the housing 10 is used in a vehicle 1000 and the top of the housing 10 forms the chassis of the vehicle 1000, the first direction F1 may correspond to the front-to-rear direction of the vehicle 1000. Among the circumferential side walls n of the main body 11, first wall portions n1 correspond to both left and right circumferential side walls n of the battery 100. The first wall portions n1 extend along the first direction F1, i.e., the front-to-rear direction of the vehicle 1000. The two first wall portions n1 are spaced apart in the left-to-right direction of the vehicle 1000. Sub-beams 13a are installed on both of the two first wall portions n1, and each sub-beam 13a and each first wall portion n1 have the same extension direction.

[0124] The structure of the sub-beams 13a in each first wall portion n1 may be the same, thereby ensuring that the pressing force resistance capacity is consistent on both the left and right sides of the vehicle 1000. Furthermore, the sub-beams 13a in the first wall portion n1 include the upper arm beam 131 and the lower arm beam 132 mentioned in the above embodiment, and in this case, the pressing force resistance capacity of the sub-beams 13a is relatively high, which compensates for the relatively weak structure on both the left and right sides of the vehicle 1000, strengthens the pressing force resistance capacity on both the left and right sides of the vehicle 1000, and improves the safety of the vehicle 1000.

[0125] At this time, sub-beams 13a are installed on each first wall portion n1, which can reinforce the structural strength of each first wall portion n1 and improve the pressing resistance of each first wall portion n1, that is, improve the pressing resistance of the left and right sides of the vehicle 1000. As can be seen, since each sub-beam 13a extends along the first direction F1, it can further improve the bending resistance of the vehicle 1000 in the fore-and-aft direction.

[0126] In some embodiments, still referring to FIG. 6, the circumferential side wall n further includes two spaced apart second wall portions n2, each extending along a second direction F2 perpendicular to the first direction F1, the two first wall portions n1 being connected to the two second wall portions n2 at a distance, and the at least two sub-beams 13a further include two second sub-beams 13a2, each arranged on the two second wall portions n2, and both extending along the first direction F1.

[0127] In practical applications, the second direction F2 may correspond to the left-right direction of the housing 10. In this case, the second wall portion n2 corresponds to the circumferential side walls n in both the front and rear directions of the battery 100. The second wall portion n2 extends along the second direction F2, i.e., the left-right direction of the vehicle 1000.

[0128] The sub-beams 13a in each second wall portion n2 may have the same structure, thereby ensuring that the front and rear pressure-resistant capabilities are consistent. Furthermore, the sub-beams 13a in the first wall portion n1 may include only the upper arm beam 131 mentioned in the above embodiment, which is installed close to the top of the body 11. In this case, the sub-beams 13a have a relatively weak pressure-resistant capability. This is mainly because pressure-resistant structures such as bumpers are generally installed in the front and rear directions of the vehicle 1000. When the vehicle 1000 is subjected to pressure in the front and rear directions, the pressure-resistant effect is mainly achieved by the front and rear bumpers. In this case, the sub-beams 13a in the second wall portion n2 have a relatively weak pressure-resistant capability. Therefore, a sub-beam 13a structure with a relatively simple structure may be used, which can reduce the costs of the battery 100 and the vehicle 1000.

[0129] At this time, sub-beams 13a are installed on each second wall portion n2, which can reinforce the structural strength of each second wall portion n2 and improve the pressure resistance of each second wall portion n2, that is, improve the left and right pressure resistance of the vehicle 1000. As can be seen, since each sub-beam 13a extends along the second direction F2, it can further improve the bending resistance of the vehicle 1000 in the left and right direction.

[0130] In some embodiments, still referring to FIG. 6, the lateral beam 13 includes at least two first sub-beams 13a1 and at least two second sub-beams 13a2, both of which are provided on the circumferential side wall n, the first sub-beams 13a1 extending along a first direction F1 and spaced apart from each other, and the second sub-beams 13a2 extending along a second direction F2 intersecting the first direction F1 and spaced apart from each other.

[0131] At this time, the sub-beams 13a provided on the first wall portion n1 are first sub-beams 13a1, and the sub-beams 13a provided on the second wall portion n2 are second sub-beams 13a2. The two first sub-beams 13a1 can reinforce the pressing force resistance of the housing 10 in the left-right direction of the vehicle 1000, and the two second sub-beams 13a2 can reinforce the pressing force resistance of the housing 10 in the front-rear direction of the vehicle 1000. In this way, the pressing force resistance of the housing 10 in the side direction of the vehicle 1000 can be increased. Endurance The pushing ability can be improved in an overall manner, and the safety performance of the vehicle 1000 can be improved.

[0132] In some embodiments, with continued reference to FIG. 6, the top of the side beam 13 is configured with a hook portion 13a3.

[0133] The hook portion 13a3 can be described above and will not be further explained here. The hook portion 13a3 is installed on the top of the side beam 13, and the housing 10 of the present embodiment can be obtained by adding the side beam 13 based on the structure of the conventional housing 10. This significantly reduces the cost of modifications. At the same time, since the hook portion 13a3 is installed on the side beam 13 and the side beam 13 does not need to define the receiving cavity s, the installation of the hook portion 13a3 does not need to consider the effect of the hook portion 13a3 on the sealing performance of the receiving cavity s, making the installation of the hook portion 13a3 more flexible. Furthermore, since the side beam 13 is located on the side edge of the housing 10, installing the hook portion 13a3 on the side beam 13 allows for a larger operating space and makes it easier to attach the housing 10 to an external device.

[0134] In some embodiments, the hook portion 13a3 includes at least one hook hole k1 provided at the top of the side beam 13.

[0135] The introduction of the hook hole k1 can be referred to the above description, and will not be further described here. The hook hole k1 is provided at the top of the side beam 13, and has the beneficial effect that the hook portion 13a3 is installed at the top of the side beam 13, and will not be further described here.

[0136] In some embodiments, the top surface h1 of the main body 11 together with the top surfaces h2 of the side beams 13 define and form the top surface h of the housing 10.

[0137] The top surface h1 of the main body 11 refers to the outer surface of one side of the main body 11 located at its top and away from the accommodating cavity s, and the top surface h2 of the side beam 13 refers to the outer surface of one side of the side beam 13 located at its top. When the side beam 13 includes the upper arm beam 131 and the lower arm beam 132 in the above embodiment, the top surface h2 of the side beam 13 refers to the outer surface of the upper arm beam 131 located at one side away from the lower arm beam 132.

[0138] When the housing 10 includes both the main body 11 and the side beams 13 in the above embodiment, the top surface h of the housing 10 may be defined by the top surface h1 of the main body 11 and the top surface h2 of the side beams 13. Here, the top surface h1 of the main body 11 and the top surface h2 of the side beams 13 may be coplanar. In this case, the contact area between the top surface h of the housing 10 and the external device is relatively large, which contributes to improving the connection reliability between the housing 10 and the external device, and at the same time, the top structure of the housing 10 is relatively flat and more aesthetically pleasing. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beams 13 do not have to be coplanar.

[0139] As can be understood, when the side beam 13 includes at least two sub-beams 13a, the top surface of each sub-beam 13a defines a portion of the top surface h2 of the side beam 13, and the sub-beams 13a are provided with hook portions 13a3. Here, the hook portions 13a3 may be provided on some of the sub-beams 13a, or on all of the sub-beams 13a. When the hook portions 13a3 are provided on some of the sub-beams 13a, the hook portions 13a3 are provided on all of the symmetrically arranged sub-beams 13a to ensure uniformity of the load received by the hook portions 13a3. The symmetrically arranged sub-beams 13a may include two first sub-beams 13a1 in the above embodiment and two second sub-beams 13a2 in the above embodiment.

[0140] In some embodiments, referring to Figures 6 and 10, a wiring portion 13a4 is configured on the outer wall of the housing 10, and the wiring portion 13a4 is located below the top surface h of the housing 10, and a wiring space is formed for drilling a wire harness.

[0141] The outer wall of the housing 10 is an outer surface that faces the inner surface that defines the storage cavity s in the housing 10. The wiring portion 13a4 is located below the top surface of the housing 10, that is, the wiring portion 13a4 is installed on the outer wall that is located below the top surface h of the housing 10. The outer wall of the housing 10 that is located below the top surface h includes a bottom surface and a side wall that connects the top surface h and the bottom surface.

[0142] When the housing 10 includes only the main body 11, the side wall of the housing 10 may be the circumferential side wall n of the main body 11. When the housing 10 includes the main body 11 and the lateral beams 13, the side wall of the housing 10 includes the circumferential side wall n of the main body 11 that is not covered by the lateral beams 13 and the surfaces of the lateral beams 13 that are away from the main body 11.

[0143] The wiring portion 13a4 is located outside the housing cavity s and has a wiring space through which a wire harness for connecting the battery cell and the power consumption device component to supply power passes. The specific form of the wiring space is not limited, and it is sufficient if it has an inlet for the wire harness to enter and an outlet for the wire harness to exit, and the inlet and outlet may be the same opening. The wiring space may also be a wiring hole or a wiring groove k2.

[0144] Specifically, the wiring portion 13a4 may be installed on the circumferential outer wall of the housing 10, and in this case, the wire harness may be routed through the side surface of the housing 10, which makes wiring relatively easy. Specifically, the wiring portion 13a4 may be installed on the bottom surface of the housing 10, and in this case, the wire harness may be routed through the bottom of the housing 10.

[0145] In this case, by forming the wiring portion 13a4 on the outer wall of the housing 10, the wire harness can be routed through the wiring space formed by the wiring portion 13a4, thereby effectively protecting the wire harness and preventing the wire harness from being pressed and deformed when the vehicle 1000 is pressed from the outside, thereby preventing unnecessary safety risks.

[0146] In a further embodiment, with continued reference to FIGS. 6 and 10, the wiring portion 13a4 is disposed on a side wall of the housing 10 adjacent to its top surface h.

[0147] The sidewalls are outer surfaces that connect the top surface h and the bottom surface (the surface opposite the top surface h) of the housing 10 itself. The wiring portion 13a4 may be provided on only some of the sidewalls of the housing 10, for example, only one or two sidewalls of the housing 10 in the first direction F1, or only one or two sidewalls of the housing 10 in the second direction F2. Of course, the wiring portion 13a4 may be provided on all of the sidewalls of the housing 10.

[0148] In this case, the wiring portion 13a4 is arranged on the side wall of the housing 10, and since the side operation space of the housing 10 is large, the wiring harness can be arranged more easily.

[0149] In some embodiments, the wiring portion 13a4 is disposed on two side walls of the housing 10 adjacent to the top surface h and facing each other.

[0150] The two side walls of the housing 10 adjacent to the top surface h and facing each other include two side walls facing back to back in the first direction F1 and two side walls facing back to back in the second direction F2. In this case, the wiring portions 13a4 may be arranged symmetrically opposite each other in the first direction F1 or opposite each other in the second direction F2, and the wire harness may be simultaneously wired from both sides of the housing 10 in the first direction F1 or from both sides of the housing 10 in the second direction F2, thereby realizing a symmetrical arrangement of the wire harness, which is more aesthetically pleasing and also contributes to the weight balance of the vehicle 1000.

[0151] Furthermore, the wiring portion 13a4 is arranged on two side walls of the housing 10 in the second direction F2, i.e., two side walls of the housing 10 corresponding to the left and right directions of the vehicle 1000. Since various electric drive systems (used to provide power for the vehicle 1000 to move forward) on the vehicle 1000 are mainly arranged on the front or rear side, the wire harness is connected to the battery 100 and the electric drive system mainly along the fore-and-aft direction of the vehicle 1000, and arranging the wiring portion 13a4 in this manner makes it easier to wire the wire harness.

[0152] 6 and 10, the wiring portion 13a4 includes a wiring groove k2 recessed into the outer wall of the housing 10 toward the receiving cavity s.

[0153] As can be seen, the wiring groove k2 forms a wiring space recessed toward the receiving cavity s and open on one side, with the opening facing the groove bottom of the wiring groove k2. The wiring groove k2 is recessed toward the receiving cavity s and may further have an inlet and an outlet. Specifically, the inlet of the wiring groove k2 may be an opening at one end of the wiring groove k2 in the extension direction, and the outlet of the wiring groove k2 may be an opening at the other end of the wiring groove k2 in the extension direction.

[0154] When the wiring groove k2 is located on the side wall of the housing 10 in the second direction F2, the wiring groove k2 may extend along the first direction F1. When the wiring groove k2 is located on the side wall of the housing 10 in the first direction F1, the wiring groove k2 may extend along the second direction F2.

[0155] In this case, since the wiring groove k2 has an opening, the provision of the opening makes it easier to drill the wire harness. In addition, the wiring portion 13a4 is configured by the wiring groove k2 formed by the recess, and there is no need to add a structure to form another wiring space, so the structure of the housing 10 is simpler and the cost is lower.

[0156] Of course, in other embodiments, the wiring portion 13a4 may have a structure with a wiring hole that is separately installed on the outer wall of the housing 10, and may be, for example, a wiring rod with a wiring hole.

[0157] In some embodiments, referring to FIGS. 6 and 10, the side beam 13 is formed by configuring the wiring portion 13a4.

[0158] Specifically, when the wiring portion 13a4 is the wiring groove k2, the side beam 13 may be configured with the upper arm beam 131 and the lower arm beam 132 in the above embodiment, and the space between the upper arm beam 131 and the lower arm beam 132 is the space where the wiring groove k2 is located. Alternatively, the outer surface of the side beam 13 away from the main body 11 is recessed to form the wiring groove k2.

[0159] The wiring portion 13a4 is a wiring hole, and the side beam 13 is a hollow beam that penetrates along both ends in its extension direction, and in this case, the internal space of the side beam 13 may be formed by configuring the wiring hole. Alternatively, the side beam 13 includes the upper arm beam 131, the lower arm beam 132, and the intermediate beam (not shown) in the above embodiment, and the intermediate beam, the upper arm beam 131, and the lower arm beam together surround the wiring hole.

[0160] At this time, the wiring portion 13a4 forms the side beam 13, i.e., the side beam 13 is provided with a wiring space, which reduces the weight of the side beam 13 and also enables wiring, thus achieving two goals.

[0161] In a specific embodiment, the upper arm beam 131 and the lower arm beam 132 are both configured to form a wiring section 13a4 having a wiring space. In this case, the wiring space is formed by the space between the upper arm beam 131 and the lower arm beam 132, so the structure of the wiring section 13a4 is simple and achieves two goals.

[0162] Fig. 11 is a schematic diagram of a local structure of a battery 100 in some other embodiments of the present application, Fig. 12 is an exploded side view of the structure shown in Fig. 11, Fig. 13 is a side view of the structure shown in Fig. 11, and Fig. 14 is an enlarged view of part D of the structure shown in Fig. 12. Fig. 15 is a schematic diagram of an application scenario of the structure shown in Fig. 11, and Fig. 16 is a side view of the structure shown in Fig. 14.

[0163] In some embodiments, referring to FIG. 11, the housing 10 further includes a sealant 12, which is provided on the top of the housing 10 and is used for sealing connection with an external device.

[0164] The sealant 12 is a component that can prevent fluids or solid particles from leaking between adjacent bonding surfaces. The sealant 12 is provided on the top of the housing 10 and divides the top of the housing 10 into an external region located on the outer periphery of the sealant 12 and an internal region surrounded by the sealant 12. The sealant 12 seals and connects the top of the housing 10 with two surfaces facing an external device and forms a contact interface between these two surfaces, preventing fluids or solid particles from the external region around the periphery of the sealant 12 from entering the internal region surrounded by the sealant 12 through the contact interface between itself and the two surfaces, thereby achieving a sealing effect.

[0165] The seal 12 may optionally be a seal ring or a gasket. Specifically, the seal 12 may optionally be made of a material such as rubber or silica gel. Specifically, the seal 12 may optionally be an O-ring seal, a rectangular seal, or an irregular seal. The specific shape of the seal 12 may be adapted to the shapes of the top of the housing 10 and the two opposing surfaces of the external device. For example, if the top of the housing 10 and the two opposing surfaces of the external device are rectangular, the seal 12 may be a rectangular seal.

[0166] At this time, the housing 10 of the battery 100 realizes a sealed connection with the external device by the sealing material 12, which provides a reliable seal and is relatively inexpensive.

[0167] As can be understood, the housing 10 of the battery 100 is sealed with the external device by the sealing material 12, and is also fixedly connected to the external device by the latch portion 13a3, and at this time the top surface h of the housing 10 comes into contact with the external device.

[0168] For example, if the external device is the body 200 of the vehicle 1000, the battery 100 may be attached to the bottom of the body 200 and be sealed and connected to the body 200 via the sealant 12 in the sealing area hc. In this case, the internal area of ​​the sealant 12 is the inside of the body 200, and the external area is the outside of the body 200. Fluids or solid particles outside the body 200 cannot leak into the inside of the body 200. For example, stones or liquids scattered while the vehicle 1000 is running cannot impact the inside of the body 200, thereby realizing the internal sealing and structural reliability of the body 200.

[0169] 7 and 11, in some embodiments, an attachment location 141b is configured on one side of the top of the housing 10 away from the receiving cavity s. Here, the battery 100 is attached to an external device via the top of the housing 10, and the attachment location 141b forms a part of the structure of the external device.

[0170] The mounting position 141b is a mounting area for mounting a certain structure (hereinafter referred to as a mounting member) formed by a localized region on the top of the housing 10. This mounting member may be a part of a structure of an external device, and the mounting position 141b may be a structure having a connecting function, such as a mounting buckle or a mounting hole. For example, if the external device is the body 200 of the vehicle 1000, the mounting position 141b is used to mount a structure such as a seat 300 of the vehicle 1000 or an operating lever, and the seat 300 or the operating lever is fixedly connected to the mounting position 141b on the top of the housing 10 by a structure such as a mounting buckle or a mounting hole.

[0171] Specifically, the mounting member attached to the mounting position 141b may be a local structure of the external device, and is used to mount the mounting position 141b of the local structure of the external device. After the top of the housing 10 is connected to the external device, it also forms a part of the structure of the external device. At this time, the battery 100 is attached to the external device through the top of the housing 10. After the mounting position 141b of the top of the battery 100 is formed into a local structure of the external device, the mounting member is connected to the housing 10 of the battery 100 to realize the connection with the external device. In this way, the battery 100 and part of the structure of the external device are installed as an integrated unit, and part of the structure of the casing 10 of the battery 100 becomes part of the structure of the external device, thereby avoiding the need for the battery 100 and the external device to be installed separately.

[0172] In other embodiments, the mounting member attached to mounting position 141b may be a structure other than an external device, and by attaching it to mounting position 141b, a fixed connection with battery 100 and the external device is simultaneously achieved.

[0173] In a specific embodiment, as shown in Figures 14 and 15, the external device is the body 200 of the vehicle 1000, and the mounting position 141b is used to mount the seat 300. By configuring the mounting position 141b on the top of the housing 10 of the battery 100, the mounting position 141b forms the internal structure of the body 200, and the battery 100 and the body 200 are integrated into one, thereby avoiding the need for separate installation of the battery 100 and the body 200, and making the structure of the vehicle 1000 simpler, smaller, and more compact.

[0174] As can be seen, the fixed connection of the housing 10, the body 200 and the seat 300 can ensure that all structures are connected vertically to the top and bottom of the housing 10, reducing the installation space and mounting force required in other directions of the housing 10, reducing the force applied to the side and bottom structures of the housing 10 by the battery 100, and improving the stability of the vehicle 1000 structure.

[0175] In some embodiments, referring to FIG. 7, the mounting location 141b includes a mounting hole configured in the top of the housing 10.

[0176] The mounting holes are through-holes that pass through the mounting positions 141b in the vertical direction, and require fasteners when mounting the mounting sheet 300 or the like to the mounting positions 141b. The mounting holes may be smooth through-holes (for example, when the fasteners are rivets), threaded through-holes (for example, when the fasteners are screws), or other types of through-holes (for example, hexagonal holes, square holes, elongated holes, etc.). The specific type of the fixing holes 11c3 is determined based on the specific type and specific setting method of the fasteners, and will not be further described here.

[0177] The number of mounting holes is the same as the number of fasteners, and one fastener is installed corresponding to each mounting hole. The fastener is used to mount and position the corresponding mounting member within the mounting hole, thereby realizing the fixation between the mounting member and the housing 10 of the battery 100 and at the same time realizing a fixed connection between the mounting member and an external device.

[0178] In other embodiments, the attachment location 141b may include other structures on the top of the housing 10, such as, but not limited to, a buckle, a spring lock, etc.

[0179] 4 to 7 and 11, in some embodiments, the housing 10 includes a main body 11 and a mounting beam 141, the main body 11 surroundingly defines a receiving cavity s, and the top of the main body forms at least a portion of the top of the housing 10. The mounting beam 141 is provided on the top of the main body 11, and has a mounting position 141b on one side away from the main body 11.

[0180] The main body 11 may be a one-piece structure or may be formed by assembling a plurality of parts, and the specific installation manner thereof has already been described in detail above, so further description will not be given here.

[0181] The top of the housing 10 has a top surface h on one side away from the receiving cavity s, and the mounting position 141b and the top surface h are in communication with each other. The mounting beam 141 is a structure with a certain load-bearing capacity provided on one side of the top of the main body 11, and is used to share the acting force from the mounting member received by the top of the housing 10. As shown in Figures 15 and 16, when the mounting member is a seat 300, when an operator sits on the seat 300, the pressure is applied, and the pressure is first applied to the mounting beam 141 and then to the top of the housing 10.

[0182] The mounting beam 141 may be installed directly on the surface of the top surface h or in a recessed or protruding portion configured and formed on the top surface h, and one or more load-bearing structures included in the mounting beam 141 configure and form mounting positions 141b on one side away from the top surface h for fixing a mounting member, thereby realizing a connection between the mounting member and the top of the housing 10.

[0183] The installation format and extension direction of the load-bearing structure are set based on the size, weight and specific structure of the mounting member that needs to be attached to the mounting position 141b, and are not specifically limited. The mounting beam 141 shares the force that the top of the main body 11 receives, thereby improving the load-bearing capacity of the housing 10 of the battery 100.

[0184] In some embodiments, the mounting beam 141 is fixedly connected to or integrally formed with the body 11 .

[0185] The mounting beam 141 and the main body 11 may be fixedly connected by fastening, engaging with an engaging structure, welding, adhesive, hot melt connection, etc. Of course, the mounting beam 141 and the main body 11 may be integrally formed by injection molding, die casting, forging, cold pressing, hot pressing, etc.

[0186] If the main body 11 is made of a metal material (e.g., aluminum, iron, stainless steel, etc.), the mounting beam 141 and the main body 11 may be integrally molded using methods such as die casting, forging, hot pressing, or cold pressing. If the main body 11 is made of a plastic material (e.g., PP, PE, ABS, etc.), the mounting beam 141 and the main body 11 may be integrally molded using injection molding. The mounting beam 141 and the main body 11 may be connected after being molded separately. If the mounting beam 141 and the main body 11 are made of a metal material, the mounting beam 141 and the main body 11 may be welded or bonded together. If the mounting beam 141 and the main body 11 are made of a plastic material, the mounting beam 141 and the main body 11 may be bonded together.

[0187] When the mounting beams 141 are fixedly connected to the main body 11, the molding process of the mounting beams 141 and the main body 11 is relatively easy, and the processing cost of the housing 10 can be reduced.

[0188] When the mounting beam 141 is integrally formed with the main body 11, the assembly of the housing 10, the external device, and the mounting member is easy.

[0189] In other embodiments, the main body 11 is connected to a part other than the mounting beam 141, and the connection method may be integral molding or fixed connection.

[0190] In some embodiments, referring to Figures 7 and 11, the mounting beam 141 includes at least one protrusion 141a, each of which protrudes from the top of the main body 11 in a direction away from the accommodating cavity s, and each of which forms a weight reduction passage 141a1 together with the main body 11, and the mounting position 141b is configured on one side of the protrusion 141a facing away from the main body 11.

[0191] The protrusions 141a are load-bearing structures included in the mounting beams 141 described above, and protrude in a direction away from the receiving cavity s relative to the plane on which the top surface h of the housing 10 is located. The protrusions 141a themselves have a certain height, which allows them to protrude from the top surface h of the housing 10. The mounting positions 141b are formed on one side of each of the protrusions 141a that is away from the main body 11. At this time, when a mounting member is attached to the mounting positions 141b, it comes into direct contact with the protrusion 141a structure but not with the top surface h, thereby dispersing the force received by the top of the housing 10 via the protrusions 141a and increasing the load-bearing capacity of the top of the housing 10.

[0192] Each protrusion 141a may have a structure surrounded by multiple faces and open at one end, and the top surface h1 of the main body 11 covers the open opening of each protrusion 141a, thereby forming a weight-reducing passage 141a1. The weight-reducing passage 141a1 may be formed by hollowing out the interior of the protrusion 141a or by drilling or grooving, thereby achieving a lightweight design for the housing 10.

[0193] In a specific embodiment, each protrusion 141a has a weight-reducing passage 141a1 that penetrates the interior of the protrusion 141a along its extension direction, and the provision of the weight-reducing passage 141a1 reduces the weight of each protrusion 141a, thereby reducing the overall weight and cost of the housing 10. Each weight-reducing passage 141a1 that penetrates the interior can form a hidden passage, and in other embodiments, the hidden passage can be used to perform operations such as dark line placement.

[0194] In some embodiments, referring to FIGS. 6 and 7, all of the protrusions 141a extend in the same direction and are spaced apart from one another.

[0195] The direction referred to by "same direction" may be specifically the first direction F1 or the second direction F2 mentioned above, or may be a direction that is on the same plane as and intersects with the first direction F1 and the second direction F2, and is not specifically limited.

[0196] "All of the protrusions 141a are spaced apart" means that a set distance is maintained between each pair of adjacent protrusions 141a in a direction intersecting the extension direction of the protrusions 141a. This set distance forms a buffer space between each pair of adjacent protrusions 141a, preventing external forces acting on the mounting beams 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the multiple spaced protrusions 141a can form a sufficiently large support area and fixing positions, thereby enabling mounting components to be supported over a large area and adaptable to mounting components of different volumes and sizes.

[0197] All of the protrusions 141a are arranged parallel to one another in the same direction, so that the buffering space extends in the same direction as the protrusions 141a. In practical applications, buffering can be achieved at any position in the extension direction of the mounting beam 141.

[0198] The set spacing distance between each two adjacent protrusions 141a may or may not be equal, and as can be understood, in order to ensure uniform support of the mounting member, the set spacing distance between each two adjacent protrusions 141a is equal.

[0199] In some embodiments, the sides of all the protrusions 141a facing away from the main body 11 are flush with each other.

[0200] All the protrusions 141a are protruded in the same direction, and all the protrusions 141a have the same protruding height, so that one side of all the protrusions 141a facing away from the mounting cavity forms a flat surface in a certain direction, for example, a flat surface in a horizontal plane, and the mounting member is placed on the flat surface for mounting, which makes the mounting more stable and simple, and also achieves a strong connection between the mounting member and the mounting beam 141.

[0201] In a specific embodiment, the protrusions 141a may be rectangular pillar-shaped structures, and the same sides of all the protrusions 141a are located in the same plane and together define and form mounting positions 141b for mounting the mounting members, thereby stably positioning the mounting members on the mounting beam 141.

[0202] In some embodiments, referring to Figures 4, 7 and 11, the housing 10 further includes side impact reinforcement beams 14 that are mounted on the top of the main body 11 and extend from the center of the top of the main body 11 to opposite outer edges of the top of the main body 11.

[0203] The side impact reinforcement beam 14 refers to a beam structure installed on top of the main body 11 to reinforce the strength of the main body 11. As can be understood, the side impact reinforcement beam 14 is located outside the main body 11. Specifically, the main body 11 and the side impact reinforcement beam 14 may be integrally connected together or may be connected together by assembly. Integral connection includes, but is not limited to, welding, integral molding, welding, etc. Assembly connection includes, but is not limited to, fastening, screw connection, etc.

[0204] The side impact reinforcement beams 14 may extend from the center of the top of the main body 11 to opposite outer edges of the top of the main body 11 in a first direction F1, in which case the side impact reinforcement beams 14 can reinforce the side impact prevention capability of the housing 10 in the first direction F1. The side impact reinforcement beams 14 may extend from the center of the top of the main body 11 to opposite outer edges of the top of the main body 11 in a second direction F2, in which case the side impact reinforcement beams 14 can reinforce the side impact prevention capability of the housing 10 in the second direction F2.

[0205] The side impact reinforcement beam 14 may extend from the center of the top of the body 11 along two collinear directions to opposite outer edges of the top of the body 11, or may extend from the center of the top of the body 11 along two intersecting directions to opposite outer edges of the top of the body 11. When the side impact reinforcement beam 14 extends from the center of the top of the body 11 along two collinear directions to opposite outer edges, the side impact reinforcement beam 14 is realized by a single straight beam, which has a simpler structure.

[0206] The side impact reinforcement beams 14 may extend to the outer edges on both sides, to the region between the outer edges on both sides and the center, or to a region other than the outer edges on both sides. In other words, the specific extension length of the side impact reinforcement beams 14 is not limited, as long as they extend from the center of the top of the main body 11 toward the outer edges on opposite sides of the top of the main body 11.

[0207] When the battery 100 is applied to a vehicle 1000 and the top structure of the housing 10 is the chassis of the vehicle 1000, the vehicle 1000 has relatively poor side collision prevention capabilities in the left-right direction. Therefore, the side collision reinforcement beams 14 may be designed to extend from the center of the top of the main body 11 to the outer edges on both sides of the top of the main body 11 in the left-right direction of the vehicle 1000, thereby reinforcing the side collision prevention capabilities of the vehicle 1000 in the left-right direction and improving the safety performance of the vehicle 1000.

[0208] In this case, by installing a side impact reinforcement beam 14 on the top of the main body 11 of the housing 10, the side impact prevention capability of the housing 10 can be improved, and further, the side impact prevention capability of the vehicle 1000 equipped with the battery 100 made of this housing 10 can be improved, thereby contributing to ensuring the safety performance of the battery 100 and the vehicle 1000.

[0209] When the main body 11 includes a frame 11b and a support member 11a, the side impact reinforcement beam 14 is installed at least on the top of the support member 11a. In this case, the top of the support member 11a forms at least a part of the top of the main body 11, so the support member 11a has sufficient space to attach the side impact reinforcement beam 14.

[0210] In some embodiments, the side impact reinforcement beam 14 extends to connect to the top of the frame 11b.

[0211] In this case, the top of frame 11b also forms part of the top of main body 11, and side impact reinforcement beam 14 can be further extended until it is connected to the top of frame 11b. In addition to being directly connected to frame 11b and support member 11a, the connection between frame 11b and support member 11a can also be further strengthened by side impact reinforcement beam 14, thereby improving the reliability of the connection between frame 11b and support member 11a.

[0212] In some embodiments, the number of side impact reinforcement beams 14 is at least one, and all of the side impact reinforcement beams 14 extend along the same direction and are spaced apart from one another.

[0213] The direction referred to by "same direction" may be specifically the first direction F1 or the second direction F2 mentioned above, or may be a direction that is on the same plane as and intersects with the first direction F1 and the second direction F2, and is not specifically limited.

[0214] All of the side impact reinforcement beams 14 extend along the same direction, and each of the side impact reinforcement beams 14 can reinforce the side impact prevention capability of the housing 10 in the extension direction, thereby strengthening the side impact prevention capability of the housing 10 in this extension direction. As can be understood, each of the side impact reinforcement beams 14 is arranged at intervals along a direction intersecting this "same direction," and in this way can reinforce the strength at multiple positions of the housing 10, making the structural strength and side impact prevention capability of the housing 10 more uniform.

[0215] In some embodiments, at least one of the side impact reinforcement beams 14 is configured as a mounting beam 141 with a mounting location 141 b configured on one side of the mounting beam 141 away from the body 11 .

[0216] The mounting beam 141 and the mounting position 141b can be described above and will not be further described here. When the side impact reinforcement beam 14 includes one beam, the beam 14 is used as the mounting beam 141. When the side impact reinforcement beam 14 includes at least two beams, the beam 14 can partially function as the mounting beam 141. Specifically, when the side impact reinforcement beam 14 includes at least two beams, the beam 14 closest to the front of the vehicle 1000 can be used as the mounting beam 141 to mount the seat 300 (the seat 300 may be the seat 300 in the driver's cab).

[0217] In this case, at least one of the side impact reinforcement beams 14 is used as the mounting beam 141, which not only provides a side impact prevention effect but also allows other mounting members to be attached, so that one beam can be used for both purposes.

[0218] In some embodiments, the side impact reinforcement beam 14 includes at least one protrusion 141a, each of which protrudes from the top of the main body 11 in a direction away from the accommodating cavity s, and each of which forms a weight reduction passage 141a1 together with the main body 11.

[0219] The protrusion 141a of the side impact reinforcement beam 14 has the same structure as the protrusion 141a mentioned when introducing the structure of the mounting beam 141 in the above embodiment, and for a detailed description, please refer to the above description. The protrusion 141a protrudes in a direction away from the receiving cavity s with respect to the plane on which the top surface h1 of the main body 11 is located, and the protrusion 141a itself has a certain height so that it protrudes from the top surface h1 of the main body 11.

[0220] Each protrusion 141a may have a structure surrounded by multiple faces and open at one end, and the top surface h1 of the main body 11 covers the open opening of each protrusion 141a, thereby forming a weight-reducing passage 141a1. The weight-reducing passage 141a1 may be formed by hollowing out the interior of the protrusion 141a or by drilling or grooving, thereby achieving a lightweight design for the housing 10.

[0221] In a specific embodiment, each protrusion 141a has a weight-reducing passage 141a1 that penetrates the interior of the protrusion 141a along its extension direction, and the provision of the weight-reducing passage 141a1 reduces the weight of each protrusion 141a, thereby reducing the overall weight and cost of the housing 10. Each weight-reducing passage 141a1 that penetrates the interior can form a hidden passage, and in other embodiments, the hidden passage can be used to perform operations such as dark line placement.

[0222] In some embodiments, referring to FIG. 7, all of the protrusions 141a extend in the same direction and are spaced apart from one another.

[0223] "All of the protrusions 141a are spaced apart" means that a set distance is maintained between each pair of adjacent protrusions 141a in a direction intersecting the extension direction of the protrusions 141a. This set distance forms a buffer space between each pair of adjacent protrusions 141a, preventing external forces acting on the mounting beams 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the multiple spaced protrusions 141a can form a sufficiently large support area and fixing positions, thereby enabling mounting components to be supported over a large area and adaptable to mounting components of different volumes and sizes.

[0224] Since all of the protrusions 141a are installed parallel to one another in the same direction, the buffer space extends in the same direction as the protrusions 141a. In practical applications, buffering can be achieved at any position in the extension direction of the side impact reinforcement beam 14.

[0225] The set spacing distance between each two adjacent protrusions 141a may be equal or unequal, and as can be understood, when the side impact reinforcement beam 14 is used as an attachment beam 141, the set spacing distance between each two adjacent protrusions 141a is equal to ensure uniform support of the attachment member.

[0226] In some embodiments, the sides of all the protrusions 141a facing away from the main body 11 are flush with each other.

[0227] One side of all the protrusions 141a is located on the top surface h1 of the main body 11, and all the protrusions are arranged to protrude in the same direction and have the same height, so that one side of all the protrusions 141a away from the mounting cavity forms a flat plane in a certain direction, for example a flat plane in the horizontal plane, thereby realizing a strong connection between the mounting member and the mounting beam 141.

[0228] In a specific embodiment, the protrusions 141a may be rectangular pillar-shaped structures, and the same sides of all the protrusions 141a are located in the same plane and together define and form mounting positions 141b for mounting the mounting members, thereby stably positioning the mounting members on the mounting beam 141.

[0229] In some embodiments, referring to FIG. 10, a battery cavity s1 and a high-voltage cavity s2 are formed in the housing 10, which are installed independently of each other, and the battery cavity s1 is used to accommodate the battery cell 20, and the high-voltage cavity s2 is used to accommodate the high-voltage box.

[0230] The high-voltage box is an important safety barrier for the batteries 100, and is equipped with a high-voltage control system that is mainly used to turn the high-voltage circuit on or off according to the electrical control requirements of the finished vehicle, provide current and leakage detection terminals, realize controllable load shedding when the external current of the batteries 100 is too large, turn off the high-voltage circuit when a short circuit occurs in the external circuit of the batteries 100, prevent the batteries 100 from catching fire, and easily disconnect the high-voltage circuit when maintaining the batteries 100.

[0231] The battery cavity s1 and the high-pressure cavity s2 being independently located means that the battery cavity s1 and the high-pressure cavity s2 are sealed from each other. To achieve this, the battery cavity s1 and the high-pressure cavity s2 may each be formed by two independent components. For example, a first and a second independent component may be installed inside the housing 10, with the first component forming the battery cavity s1 and the second component forming the high-pressure cavity s2. Alternatively, a partition component may be installed inside the housing 10 to separate the storage cavities s formed inside the housing 10 and form the independent battery cavities s1 and high-pressure cavities s2. Alternatively, all storage cavities s formed inside the housing 10 may be battery cavities s1, and a single high-pressure chamber 15 may be configured outside the housing 10 to form the high-pressure cavity s2, thereby achieving the independence of the battery cavity s1 and the high-pressure cavity s2.

[0232] The battery cavity s1 is used to accommodate the battery cells 20, and the high-pressure cavity s2 is used to accommodate the high-pressure box. When the battery cavity s1 and the high-pressure cavity s2 are installed independently, high-temperature gas leaked due to thermal failure of the battery cells 20 in the battery cavity s1 will not enter the high-pressure box, and will not cause thermal damage to the high-pressure control system in the high-pressure box. This ensures the normal control function of the high-pressure control system and improves the safety performance of the battery 100.

[0233] In some embodiments, referring to Figures 11 to 13, the housing 10 further includes a high-pressure chamber 15, in which a battery cavity s1 is formed within the main body 11, and the high-pressure chamber 15 is provided outside the main body 11 and surrounds or surrounds together with the main body 11 to form a high-pressure cavity s2.

[0234] The high pressure chamber 15 may be a case 22 structure, the inside of which is hollow to form the high pressure chamber 15, which is used to install a high pressure box. The high pressure chamber 15 is provided outside the main body 11, and the battery cavity s1 is formed by the main body 11 (at this time, the battery cavity s1 corresponds to the receiving cavity s), thus realizing the independent installation of the high pressure cavity s2 and the battery cavity s1.

[0235] The high pressure chamber 15 forms a high pressure cavity s2 together with the main body 11, and the high pressure chamber 15 has one opening and is attached to the main body 11 through this opening. When the high pressure chamber 15 itself surrounds and forms the high pressure cavity s2, only an attachment relationship exists between the high pressure chamber 15 and the main body 11.

[0236] At this time, a high-pressure cavity s2 is defined and formed by a high-pressure chamber 15 provided outside the main body 11, and the accommodating cavity s formed in the main body 11 may accommodate a battery cell 20 as a battery cavity s1, thereby improving the electrical capacity of the battery 100.

[0237] 11 and 12, in some embodiments, the high pressure chamber 15 is provided on the top of the main body 11 so as to protrude therefrom.

[0238] The high-pressure chamber 15 protrudes from the top of the main body 11, i.e., the high-pressure chamber 15 is located outside the main body 11 and is provided on the top surface h1 of the main body 11. When the casing 10 of the battery 100 is used as the chassis of the vehicle 1000, the high-pressure chamber 15 is located on the top of the main body 11 and is not exposed to the outside of the vehicle 1000, and can be protected from external impacts (for example, stones flying while the vehicle 1000 is running), making the high-pressure chamber 15 safer.

[0239] As can be understood, when the main body 11 includes the frame 11b and the support member 11a, the support member 11a constitutes at least a part of the top of the main body 11, and the high-pressure chamber 15 is provided on the top of the support member 11a and surrounds or surrounds together with the support member 11a to form the high-pressure cavity s2. In this case, the support member 11a constitutes most of the area of ​​the top of the main body 11, so the high-pressure chamber 15 is provided on the top of the support member 11a, which provides a larger installation space for the high-pressure chamber 15 and makes the installation more stable.

[0240] Of course, if the top of the frame 11b is also configured as part of the top of the main body 11, the high-pressure chamber 15 may also be installed at the top of the frame 11b, and may be specifically set based on the mounting method of the frame 11b and the support member 11a.

[0241] For some embodiments, and with reference to FIGS. 11-13, the high pressure chamber 15 is located adjacent the top outer edge of the body 11.

[0242] The outer edge of the top of the main body 11 includes the top of the main body 11 being installed on one outer edge in the forward direction of the vehicle 1000, the top of the main body 11 being installed on one outer edge in the rearward direction of the vehicle 1000, the top of the main body 11 being installed on one outer edge in the left direction of the vehicle 1000, and the top of the main body 11 being installed on one outer edge in the right direction of the vehicle 1000.

[0243] In one application example, the high pressure chamber 15 is installed on the outer edge of one side in the rear direction of the vehicle 1000, close to the top of the main body 11, that is, the high pressure chamber 15 is arranged close to the rear of the vehicle 1000, and in this case, the high pressure chamber 15 may be arranged corresponding to the passenger space behind the driving space of the vehicle 1000, and in particular, may be arranged corresponding to below the seat 300 in the passenger space, and may not occupy the activity space of the vehicle 1000.

[0244] In some embodiments, referring to Figures 4, 6, and 11 to 13, the high pressure chamber 15 and the side impact reinforcement beam 14 are arranged sequentially in a first direction F1, and the side impact reinforcement beam 14 extends along a second direction F2 that intersects with the first direction F1.

[0245] When the housing 10 includes the side impact reinforcement beam 14 , the high pressure chamber 15 and the side impact reinforcement beam 14 may both be provided at the top of the main body 11 .

[0246] The arrangement of the high pressure chamber 15 and the side impact reinforcement beams 14 in sequence in the first direction F1 means that the high pressure chamber 15 is located on one side in the first direction F1 of all of the side impact reinforcement beams 14. Furthermore, the side impact reinforcement beams 14 extend in a second direction F2 that intersects with the first direction F1 and do not interfere with the high pressure chamber 15. The structural arrangement of the high pressure chamber 15 and the side impact reinforcement beams 14 is relatively reasonable, and the utilization rate of the top space of the body 11 is relatively high.

[0247] Regarding a specific embodiment, referring to Figure 4, the high-pressure chamber 15 includes a chamber cover 15a and a chamber box 15b, the chamber box 15b is provided on the top of the main body 11 and forms an open high-pressure cavity s2 away from the main body 11, and the chamber cover 15a is removably placed over one open side of the high-pressure cavity s2.

[0248] The connection between the chamber box 15b and the body 11 may be by welding, fusion welding, adhesive bonding, fastening, etc. Without limitation, the chamber box 15b may be made of plastic. The connection between the chamber cover 15a and the chamber box 15b may be detachably connected by fasteners or by a fastening method, and the specific form is not limited.

[0249] At this time, the chamber box 15b forms a high-pressure cavity s2, the chamber cover 15a seals the high-pressure cavity s2, and the chamber cover 15a and the chamber box 15b are detachably connected, which facilitates the installation and maintenance of the high-pressure box.

[0250] Fig. 17 is a schematic diagram of a local structure of a battery 100 in some other embodiments of the present application, Fig. 18 is a side view of the structure shown in Fig. 17, Fig. 19 is an exploded view of the structure shown in Fig. 18, and Fig. 20 is a cross-sectional view of the EE portion of the structure shown in Fig. 18. Fig. 21 is a top view of the structure shown in Fig. 17.

[0251] In some embodiments, referring to Figures 17 to 21, the housing 10 further includes an intermediate passage beam 16, which extends from the top of the main body 11 along a first direction F1 and is installed equidistant from the top of the main body 11 and from both outer edges in a second direction F2 intersecting the first direction F1, and the intermediate passage beam 16 has a wiring passage 16a for drilling a wire harness.

[0252] In a conventional vehicle 1000, a middle passage beam 16 structure is generally installed on the chassis of the body 200 of the vehicle 1000. The middle passage beam 16 is a beam structure extending from the front chassis to the rear chassis of the body 200 of the vehicle 1000, and is a main structural member that ensures the collision transmission path of the body 200 and the bottom plate rigidity of the body 200. The middle passage beam 16 is disposed in the middle region of the chassis of the vehicle 1000, and extends from the front chassis to the rear chassis in the fore-and-aft direction of the vehicle 1000.

[0253] In this embodiment, the intermediate passage beam 16 of the vehicle 1000 is directly integrated into the top of the main body 11 of the housing 10. Specifically, the intermediate passage beam 16 extends along a first direction F1 (corresponding to the front-rear direction of the vehicle body 200) and is installed equidistant from the outer edges of both sides of the top of the main body 11 in a second direction F2 (corresponding to the left-right direction of the vehicle body 200), thereby being located in the central region of the top of the main body 11.

[0254] Generally, the intermediate passage beam 16 is designed to have a hollow structure in order to reduce the weight of the vehicle body 200. In this embodiment, the hollow structure provided inside the intermediate passage beam 16 is used to form a wiring passage 16a for drilling a wire harness, which not only reduces the weight but also realizes more flexible and safer wiring harness arrangement.

[0255] The intermediate passage beam 16 may be a sheet metal member integrally formed by pressing, die casting, or the like, or may be a beam structure formed by welding, fusion welding, or fastening a plurality of sheet metal plates together, as long as it can form a wiring passage 16a for the wiring. The wiring passage 16a may be located inside the intermediate passage beam 16 (e.g., a hole inside the intermediate passage beam 16) or outside the intermediate passage beam 16 (e.g., a recessed groove passage recessed outside the intermediate passage beam 16). The intermediate passage beam 16 may form the wiring passage 16a together with the main body 11, or may form the wiring passage 16a by itself. The intermediate passage beam 16 and the main body 11 may be connected to each other by welding, fusion welding, fastening, or the like to form an integrated structure.

[0256] The wiring passage 16a provided in the intermediate passage beam 16 may extend along the extension direction of the intermediate passage beam 16 (i.e., the first direction F1), or may be designed according to other required methods, and is not specifically limited as long as wiring can be realized. A plurality of independent wiring passages 16a may be provided in the intermediate passage beam 16, thereby realizing classified wiring of various types of wire harnesses and facilitating installation and maintenance.

[0257] In this case, if the top of the housing 10 is configured to the chassis (chassis, i.e., the floor of the body 200) of the vehicle 1000, there is no need to separately install the intermediate passage beam 16, which increases the assembly efficiency of the body 200. At the same time, the hollow structure formed inside the intermediate passage beam 16 is used to form a wiring passage 16a for drilling the wire harness, which not only reduces weight but also enables more flexible wiring harness placement.

[0258] In some embodiments, referring to FIG. 20, the intermediate passage beam 16 includes a beam support 161, which is installed at the top of the main body 11, and has a wire passage groove 16a1 formed therein as a wiring passage 16a, and the wire passage groove 16a1 is recessed toward the receiving cavity s.

[0259] The beam holder 161 is directly installed on the main body 11, and may be fixed to the main body 11 by welding, fusion welding, fastening, etc. A wire-passing groove 16a1 is formed in the beam holder 161, and the wire-passing groove 16a1 is recessed toward the receiving cavity s, that is, the wire-passing groove 16a1 has a groove opening that is away from the receiving cavity s, and this groove opening makes it easy to drill the wire harness.

[0260] The wire passing groove 16a1 may be a continuous groove structure recessed into the surface of one side facing away from the accommodating cavity s of the beam support 161, or may be a wire passing section having recessed grooves recessed toward multiple accommodating cavities formed on the surface of one side facing away from the accommodating cavity s of the beam support 161, each wire passing section being arranged at intervals along the set direction, and the recessed grooves of all the wire passing sections together form the wire passing groove 16a1 of the beam support 161.

[0261] At this time, the beam support 161 forms a wire-passing groove 16a1 recessed toward the receiving cavity s, facilitating the installation of the wire harness.

[0262] In some embodiments, referring to FIG. 20, the number of the wire grooves 16a1 is plural, and all the wire grooves 16a1 extend along the same direction and are spaced apart from each other.

[0263] A plurality of the wiring grooves 16a1 may be provided, and the plurality of wiring grooves 16a1 may extend in the same direction (for example, the first direction F1) and may be spaced apart. Each wiring groove 16a1 can accommodate wiring for a Category 1 wire harness (the classification of wire harnesses can be determined according to the objects connected to the wire harness, such as a wire harness connected to an air conditioner, a wire harness connected to a lamp, a wire harness connected to a power drive system, etc.).

[0264] In this way, independent placement of wire harnesses of different categories can be realized, making installation and maintenance of the wire harnesses easier.

[0265] In some embodiments, the wire groove 16a1 is configured to engage with the wire harness through which it is drilled.

[0266] To enable the wire harness to be engaged in the wire-passing groove 16a1, the size of the opening of the wire-passing groove 16a1 corresponds to the diameter of the wire harness to be passed through it, or the two are tightly fitted together to achieve the engagement. Specifically, a fastening member is provided at the opening of the wire-passing groove 16a1, one end of the fastening member is rotatably connected to one side of the opening of the wire-passing groove 16a1, and the other end is detachably fastened to the other side of the opening of the wire-passing groove 16a1. After the wire harness is placed in the wire-passing groove 16a1, the fastening member is used to engage with the opening of the wire-passing groove 16a1 to fasten the wire harness in the wire-passing groove 16a1.

[0267] In this way, it is possible to avoid noise caused by the swinging of the wire harness, and also to avoid the problem of the wire harness coming off the wire-passing groove 16a1 and being damaged.

[0268] In some embodiments, referring to FIG. 20, the intermediate passage beam 16 further includes a beam cover 162, which is removably placed over the open side of the wire passage groove 16a1.

[0269] The opening side of the wire-passing groove 16a1 is the side where the groove mouth of the wire-passing groove 16a1 is located. The beam cover 162 is detachably fitted onto the opening side of the wire-passing groove 16a1, that is, the beam cover 162 is detachably connected to the beam bracket 161. Specifically, the beam cover 162 and the beam bracket 161 are detachably fastened together, or the beam cover 162 and the beam bracket 161 are detachably connected by fasteners (e.g., bolts). The manner of realizing the detachable connection between the beam cover 162 and the beam bracket 161 can be any common installation in the art, and will not be limited herein and will not be described further.

[0270] At this time, by covering the groove opening of the wire passage groove 16a1 with the beam cover 162, it is possible to prevent external dust and moisture from entering the wire passage groove 16a1 and corroding the wire harness, and at the same time to protect the wire harness from being crushed by external forces, thereby improving the safety of the battery 100.

[0271] In some embodiments, the high pressure cavity s2 communicates with the wire passage 16a.

[0272] As can be appreciated, a wire harness typically comes out of the high voltage box in the high voltage cavity s2 and then passes through the high voltage cavity s2 and the wire passage 16a to supply power to a power consuming device.

[0273] The high-pressure cavity s2 being in communication with the wiring passage 16a means that the wire harness emerging from the high-pressure cavity s2 can enter the wiring passage 16a. Specifically, the high-pressure cavity s2 has a wiring port, which faces the entrance of the wiring passage 16a. At this time, there is no obstacle between the wiring port and the entrance of the wiring passage 16a, and the wire harness emerging through the wiring port can directly enter the entrance of the wiring passage 16a without having to bend. Specifically, the high-pressure cavity s2 has a wiring port, which does not face the entrance of the wiring passage 16a but is spatially in communication with the entrance of the wiring passage 16a. At this time, there is an obstacle between the wiring port and the entrance of the wiring passage 16a (the obstacle may be formed by the intermediate passage beam 16 or another structure), and the wire harness emerging through the wiring port bends to bypass the obstacle before entering the wiring passage 16a via the entrance of the wiring passage 16a. At this time, the high-pressure cavity s2 communicates with the wiring passage 16a, and the wiring harness coming out of the high-pressure cavity s2 can be arranged through the wiring passage 16a.

[0274] In some embodiments, referring to Figures 17 and 21, the intermediate passage beam 16 and the high pressure chamber 15 are disposed adjacent to each other along the first direction F1.

[0275] The intermediate passage beam 16 generally extends from the front chassis of the vehicle body 200 to the rear chassis of the vehicle body 200, and the high pressure chamber 15 is located on one side of the intermediate passage beam 16 in the first direction F1, and the high pressure chamber 15 may be located in front of or behind the intermediate passage beam 16. Specifically, the high pressure chamber 15 is located behind the intermediate passage beam 16, and the high pressure chamber 15 corresponds to the position of the rear chassis of the vehicle body 200. The position of the rear chassis of the vehicle body 200 can be used to install a seat 300 in the passenger compartment of the vehicle 1000, so the high pressure chamber 15 can be hidden in the space below the seat 300, thereby improving the space utilization rate of the passenger compartment of the vehicle 1000.

[0276] In some embodiments, referring to FIG. 11, a first region ha and a second region hb are formed on the top surface h of the housing 10, the second region hb surrounds the first region ha, a plurality of hook portions 13a3 are formed in the second region hb, and the battery 100 is attached to an external device via the hook portions 13a3.

[0277] The first region ha and the second region hb may be formed by dividing them into separate regions using another structure, for example, a sealant 12 is provided on the top of the housing 10, and the top surface h of the housing 10 is divided into a second region hb located on the outer periphery of the sealant 12 and a first region ha located on the inner periphery of the sealant 12, and when the battery 100 is attached to an external device via the hook portion 13a3, the first region ha and the second region hb are independent of each other.

[0278] The first region ha and the second region hb may be automatically partitioned and formed on the top surface h, and in this case, when there is no other structural gap between the first region ha and the second region hb and the battery 100 is attached to an external device via the hook portion 13a3, the first region ha and the second region hb may be connected to each other.

[0279] Furthermore, the area size of the first region ha and the area size of the second region hb are not limited, and the first region ha and the second region hb may be flat or non-flat surfaces, and their specific structures are not limited.

[0280] In a specific embodiment, for example, when the external device is the body 200 of the vehicle 1000, the hooking portion 13a3 is configured and formed in the second region hb, so that the housing 10 is connected to the body 200 through a relatively outer region of the top. At this time, the housing 10 only receives the vertical acting force of the body 200, reducing the power transmission path and further improving the rigidity and lateral force of the completed vehicle. Endurance It is advantageous to improve the pressing ability As can be understood, the top surface h of the housing 10 may include other regions in addition to the first region ha and the second region hb, and the other regions may be located either between the first region ha and the second region hb, on the periphery of the first region ha, or inside the second region hb, and the present application is not specifically limited thereto.

[0281] In some embodiments, referring to FIGS. 13 and 14, the distance L2 between the geometric centers of the orthogonal projections of each of two adjacent hook portions 13a3 in the second region hb is 80 mm to 500 mm.

[0282] Orthogonal projection refers to projection of the hooking portions 13a3 onto the second area hb along a direction perpendicular to the projection plane, i.e., perpendicular to the second area hb. When the hooking portions 13a3 are connected to an external device, each hooking portion 13a3 has one hooking force receiving point, and the geometric center of the orthogonal projection of each hooking portion 13a3 on the second area hb is the hooking force receiving point. The distance between each two adjacent hooking force receiving points (i.e., distance L2) is limited to 80-500 mm, which ensures that the battery 100 is evenly connected to the external device and improves the connection strength between the battery 100 and the external device.

[0283] In a specific embodiment, when the external device is the body 200 of the vehicle 1000, the latching portion 13a3 is configured to include a plurality of latching holes k1, and the housing 10 of the battery 100 is connected to the body 200 through the plurality of latching holes k1. The distance L2 between the geometric centers of adjacent latching holes k1 is within a limited range, ensuring that the installation distance between the latching holes k1 (i.e., the distance L2) is controllable. Controlling the installation distance between the latching holes k1 ensures that the plurality of latching positions on the housing 10 are essentially uniformly distributed, making the force-bearing capacity of the body 200 uniform and further improving the connection rigidity between the body 200 and the housing 10 at each position.

[0284] As can be understood, in some other embodiments, when it is necessary to realize personalized settings, for example when it is necessary to divide the hooking portion 13a3 into dense hooking areas and sparse hooking areas, the distance between each hooking hole k1 in the dense hooking area (i.e., distance L2) may be set as close to one side as possible, i.e., 80 mm, and the distance between each hooking hole k1 in the sparse hooking area (i.e., distance L2) may be set as close to one side as possible, i.e., 500 mm, thereby meeting the personalized needs of local dense hooking and local sparse hooking.

[0285] In some embodiments, referring to FIGS. 13 and 14, the distance L2 between the geometric centers of the orthogonal projections of each of two adjacent hook portions 13a3 in the second region hb is 80 mm to 300 mm.

[0286] The distance L2 is within the range of 80 mm-300 mm, which can ensure the uniformity of the connection between the battery 100 and the external device, and at the same time, the strength of the connection between the battery 100 and the external device.

[0287] In some embodiments, referring to Figures 13 to 14, a seal area hc is further formed on the top surface h of the housing 10, the seal area hc is provided between the first area ha and the second area hb, and the seal area hc surrounds the first area ha, the seal area hc is used to attach a seal material 12, and the seal material 12 is used to contact an external device.

[0288] The sealing area hc is also part of the top surface h of the housing 10, and is located between the first area ha and the second area hb, separating the first area ha and the second area hb to form a non-communicating relationship. The area of ​​the sealing area hc is not too large, and its main function is to attach the sealing material 12 to achieve mutual isolation between the first area ha and the second area hb. It is installed as close as possible to the size, volume, and shape of the sealing material 12, ensuring that the entire sealing material 12 is assembled in the sealing area hc.

[0289] As can be seen, the sealant 12 has different states within the sealing area hc, and when the sealant 12 contacts an external device and the housing 10 is fixedly connected to the external device, the sealant 12 is in a compressed state, which generates a certain deformation to ensure sealing, and when the battery 100 is separated from the external device, the sealant 12 returns to its original state.

[0290] In a specific embodiment, for example, if the external device is the body 200 of a vehicle 1000, the battery 100 may be attached to the bottom of the body 200 and sealed to the body 200 via the sealant 12 in the sealing area hc, in which case the first area ha forms the sealed interior of the body 200 and the second area hb is the exterior of the body 200, and fluids or solid particles outside the body 200 cannot leak into the interior of the body 200, for example, stones or liquids scattered while the vehicle 1000 is running cannot impact the interior of the body 200, thereby realizing the internal sealing and structural reliability of the body 200.

[0291] As can be understood, when the housing 10 includes the sealant 12, the sealant 12 is attached to the seal area hc and seals and separates the first area ha and the second area hb. The specific installation form of the sealant 12 has already been described in detail above, so no further description will be given here. The top surface h of the housing 10 may include other areas in addition to the first area ha, the seal area hc, and the second area hb, and the other areas may be located inside the first area ha or outside the second area hb; the present application does not specifically limit the scope of the present application.

[0292] In some embodiments, referring to FIGS. 13 and 14, the shortest distance L1 between the geometric center of the orthogonal projection of the hook portion 13a3 in the second region hb and the outer edge of the sealing region hc is 30 mm-200 mm.

[0293] When the hooks 13a3 are projected onto the second region hb in a direction perpendicular to the second region hb and connected to an external device, each hook 13a3 has a force-receiving point, and the geometric center of the orthogonal projection of each hook 13a3 onto the second region hb is the force-receiving point of each hook 13a3. The shortest distance L1 between the geometric center of the orthogonal projection of each hook 13a3 onto the second region hb and the outer edge of the sealing region hc is the shortest distance between the force-receiving point of each hook 13a3 and the outer edge of the sealing region hc.

[0294] The outer edge of the sealing area hc is a boundary line shared between the sealing area hc and the second area hb, and of course the sealing area hc also has an inner edge, which is a boundary line shared between the sealing area hc and the first area ha. When the sealing material 12 is assembled, both side edges of the sealing material 12 overlap with the inner and outer side edges of the sealing area hc, so that the sealing material 12 completely covers the sealing area hc.

[0295] The shortest distance L1 between the geometric center of the orthogonal projection of the hook portion 13a3 in the second region hb and the outer edge of the sealing region hc is the length of a perpendicular line drawn from the geometric center of each hook portion 13a3 to the outer edge of the sealing region hc, and ensures that the distance between the sealing material 12 and the hook portion 13a3 is within a limited range.

[0296] In a specific embodiment, for example, if the external device is the body 200 of the vehicle 1000, the shortest distance (i.e., distance L1) between the latching force receiving point of the latching portion 13a3 and the outer edge of the sealing area hc is controlled to 30 mm-200 mm, which prevents the latching force receiving point of the latching portion 13a3 from being too far away from the sealing material 12, on the one hand, ensuring the sealing effect of the sealing material 12 on the inside of the body 200, and on the other hand, reducing the latching torque with which each latching portion 13a3 is latched to the body 200, effectively shortening the latching moment arm, and ensuring the connection rigidity between the battery 100 and the body 200.

[0297] In some embodiments, referring to FIGS. 13 and 14, the shortest distance L1 between the geometric center of the orthogonal projection of the hook portion 13a3 in the second region hb and the outer edge of the sealing region hc is 50 mm-100 mm.

[0298] Within the range of 50 mm-100 mm, the latching force receiving point of the latching portion 13a3 can be prevented from being too far away from the sealing material 12, thereby ensuring the sealing isolation effect of the sealing material 12 on the first area ha and the second area hb, and at the same time ensuring the connection strength between the battery 100 and the external device.

[0299] In some embodiments, the sealing region hc is coplanar with the second region hb.

[0300] Being on the same plane, also called a coplanar plane, means that the sealing area hc and the second area hb occupy the same plane in three-dimensional space, and at this time, the sealing area hc and the second area hb are both configured as flat planes and no angle is formed between them.

[0301] In a specific embodiment, when the external device is the body 200 of the vehicle 1000 and the housing 10 is assembled to the bottom of the body 200 via the top, the sealing area hc and the second area hb have the same height in the vertical direction, the sealing area hc is used to install the sealing material 12 to perform the sealing function, and a hooking member is configured in the second area hb to perform the hooking function, at this time the hooking force receiving point of each hooking portion 13a3 and the sealing area hc are located on the same plane and at the same height, and the hooking force receiving point and the sealing material 12 only perform the vertical force resistance, thereby reducing the force receiving of the side structures of the housing 10 and the body 200 and improving the rigidity of the vehicle 1000.

[0302] In some embodiments, referring to FIG. 11, the first region ha and the second region hb are coplanar with the sealing region hc.

[0303] At this time, the plane where the first area ha and the second area hb are located on the same plane as the sealing area hc comes into contact with the external device, and the contact area between the top surface h of the housing 10 and the external device is relatively large, which contributes to improving the connection reliability between the housing 10 and the external device, and at the same time, the top structure of the housing 10 is relatively flat and more aesthetically pleasing.

[0304] When the external device is the body 200 of the vehicle 1000, the internal region of the body 200, the external region of the body 200 and the sealing region hc on the top surface h forming the housing 10 are all installed on the same plane, ensuring that the internal and external regions of the body 200 of the housing 10 only bear force in the vertical direction, thereby further reducing the force received by the lateral structure of the vehicle 1000.

[0305] In some embodiments, referring to FIG. 14, when the hook portion 13a3 includes at least one hook hole k1, all of the hook holes k1 penetrate the second region hb.

[0306] For an introduction to the fastening hole k1, please refer to the above description and no further explanation will be given here. If the fastening hole k1 is installed through the second region hb, when the connecting member connects the housing 10 to an external device, it can connect the top of the housing 10 from the second region hb, which is relatively outer than the top of the housing 10, thereby improving the connection strength between the housing 10 and the external device.

[0307] In some embodiments, referring to FIG. 14, the outer edge of the sealing area hc adjacent to the second area hb has a pre-remaining distance from the circumferential sidewall n of the body 11.

[0308] For the introduction of the holes in the circumferential side wall n of the main body 11, please refer to the above description and will not be further explained here. The outer edge of the sealing area hc adjacent to the second area hb is not on the same plane vertically as the plane on which the circumferential side wall n of the main body 11 is located, so that there is a certain predetermined distance between the outer edge of the sealing area hc and the outer edge of the top surface h1 of the main body 11.

[0309] When the sealing material 12 is assembled and no deformation occurs in the sealing material 12, both side edges of the sealing material 12 overlap with both inner and outer side edges of the sealing area hc, and when the sealing material 12 is sealed and connected to an external device, the sealing material 12 deforms and both sides overflow from the sealing area hc, with one side extending beyond the sealing area hc into the first area ha and the other side extending beyond the sealing area hc into the second area hb.

[0310] A predetermined distance is provided between the outer edge of the sealing area hc adjacent to the second area hb and the axial side wall of the main body 11, so that a deformation space sufficient for deformation of the sealing material 12 can be left in advance, and the sealing material 12 is prevented from overflowing beyond the top surface h1 of the main body 11 into other areas of the top of the housing 10 and interfering with structures on those areas when it deforms.

[0311] In some embodiments, with reference to FIGS. 11 and 13, the top surface h1 of the body 11 defines and forms at least a portion of the top surface h of the housing 10.

[0312] The top surface h1 of the main body 11 refers to the surface of the main body 11 located at its top and facing away from the receiving cavity s. When the housing 10 includes both the main body 11 and the side beams 13 in the above-described embodiment, the top surface h of the housing 10 may be defined by the top surface h1 of the main body 11 and the top surface h2 of the side beams 13. Here, the top surface h1 of the main body 11 and the top surface h2 of the side beams 13 may be coplanar. In this case, the contact area between the top surface h of the housing 10 and the external device is relatively large, contributing to improved connection reliability between the housing 10 and the external device, and at the same time, the top structure of the housing 10 is relatively flat and more aesthetically pleasing. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beams 13 do not have to be coplanar.

[0313] In other embodiments, the housing 10 may include other structures other than the main body 11 and the side beams 13, and in this case, the top surface h of the housing 10 is defined and formed by the top surface h1 of the main body 11, the top surface h2 of the side beams 13, and the top surfaces of the other structures.

[0314] As can be understood, the first area ha and the sealing area hc are located on the top surface h1 of the main body 11, and in addition to the first area ha and the sealing area hc, the top surface h1 of the main body 11 may further include other areas, which are not specifically limited here.

[0315] In some embodiments, referring to FIGS. 11 and 13, at least a portion of the second region hb and the first region ha are located on the top surface h1 of the body 11.

[0316] The top surface h1 of the main body 11 is divided into a first region ha, a sealing region hc circumferentially disposed outside the first region ha, and a second region hb circumferentially disposed outside the sealing region hc. When compressive deformation occurs in the sealing material 12 in the sealing region hc, one edge of the sealing material 12 extends into the second region hb on the top surface h1 of the main body 11.

[0317] As can be seen, the second region hb on the top surface h1 of the main body 11 is a pre-reserved distance between the outer edge of the sealing region hc adjacent to the second region hb and the circumferential side wall n of the main body 11, thereby ensuring that sufficient deformation space is pre-reserved for the deformation of the sealing material 12 and preventing the sealing material 12 from overflowing beyond the top surface h1 of the main body 11 onto the side beam 13 when it deforms.

[0318] In some embodiments, the hook portion 13a3 is located in a second region hb defined by the top surface h2 of the side beam 13.

[0319] The introduction of the hook hole k1 can be referred to the above description, and will not be further described here. The hook hole k1 is provided in the second region hb defined by the top surface h2, and has the beneficial effect that the hook portion 13a3 is installed at the top of the side beam 13, and will not be further described here.

[0320] When the housing 10 simultaneously includes the main body 11 and the side beam 13 in the above embodiment, the top surface h of the housing 10 may be defined and formed by the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. A distance may be left in advance between the outer edge of the sealing region hc adjacent to the second region hb and the axial side wall of the main body 11, thereby leaving sufficient deformation space for the sealant 12 to deform, and preventing the sealant 12 from overflowing beyond the top surface h1 of the main body 11 onto the top surface h2 of the side beam 13 and interfering with the engagement of the engagement portion 13a3 on the side beam 13.

[0321] In some embodiments, referring to FIG. 14, the hook portion 13a3 is provided on the first sub-beam 13a1 and / or the second sub-beam 13a2, and in the first direction F1 and / or the second direction F2, the distance L2 between the geometric centers of the orthogonal projections of each two adjacent hook portions 13a3 in the second region hb is 80 mm-500 mm.

[0322] The first sub-beams 13a1 and the second sub-beams 13a2 are described above and will not be described further here. The two first sub-beams 13a1 extend along a first direction F1, and the two second sub-beams 13a2 extend along a second direction F2. The first sub-beams 13a1 and / or the second sub-beams 13a2 are provided with hooks 13a3, respectively, which extend along the first direction F1 and / or the second direction F2, thereby achieving uniform hooking and fixing with an external device in multiple directions and further improving the connection between the external device and the housing 10.

[0323] Furthermore, in a certain set direction, the distance between the geometric centers of the orthogonal projections of each two adjacent hanging portions 13a3 in the second region hb is limited, and the distance between the geometric centers of adjacent hanging holes k1 is within a limited range, thereby ensuring that the installation distance between the hanging holes k1 and the hanging holes k1 along the extension direction of the first sub-beam 13a1 and the extension direction of the second sub-beam 13a2 is controllable, and making the force-bearing capacity of the car body 200 uniform.

[0324] As can be understood, when the housing 10 includes the intermediate passage beam 16, the intermediate passage beam 16 is located in the first region ha, whereby the intermediate passage beam 16 can be located in the central region of the body 11.

[0325] In one embodiment, the housing 10 includes the main body 11 and the high-pressure chamber 15, the battery cavity s1 is formed in the main body 11, the high-pressure chamber 15 is provided at the top of the main body 11 and is located in the first region ha, and the high-pressure chamber 15 surrounds or surrounds together with the main body 11 to form the high-pressure cavity s2. The first region ha forms most of the area of ​​the top of the main body 11, so by arranging the high-pressure chamber 15 in the first region ha, the space utilization rate of the first region ha can be improved.

[0326] Meanwhile, according to some embodiments of the present application, with reference to Figures 3 and 4, the present application provides a battery 100, which includes the housing 10 and the battery cell 20 described in any of the above embodiments, and the battery cell 20 is housed in a housing cavity s. Since the battery 100 includes the housing 10, it has all the beneficial effects of the housing 10, and will not be further described here.

[0327] In some embodiments, the battery 100 further includes a high-voltage box (not shown), and a battery cavity s1 and a high-voltage cavity s2 are formed in the housing 10 and installed independently of each other, with the battery cavity s1 being used to accommodate the battery cell 20 and the high-voltage cavity s2 being used to accommodate the high-voltage box.

[0328] The high-voltage box is an important safety barrier for the batteries 100, and is equipped with a high-voltage control system inside. It is mainly used to turn the high-voltage circuit on or off according to the electrical control requirements of the finished vehicle, to provide current and leakage detection terminals, to realize controllable load disconnection when the external current of the batteries 100 is too large, to turn off the high-voltage circuit when a short circuit occurs in the external circuit of the batteries 100, to prevent the batteries 100 from catching fire, and to easily disconnect the high-voltage circuit when maintaining the batteries 100.

[0329] At this time, the high-voltage box connects and collects the current of all the battery cells 20 and provides safe electrical energy to the outside, thereby realizing safe external power supply for the battery 100. For the specific structure of the high-voltage box, reference can be made to prior art in this field, and this application does not relate to specific improvements to the high-voltage box.

[0330] In some embodiments, referring to Figures 10 and 20, the housing 10 includes a main body 11 that surrounds and forms a storage cavity s, the main body 11 includes a support member 11a located at the top of the housing 10 and for defining the storage cavity s, and the battery cell 20 is mounted on the support member 11a.

[0331] The main body 11, the top of the housing 10, and the support member 11a are described above and will not be further described here. The support member 11a is a member capable of supporting the weight of the battery cells 20, and may be a support plate, a support block, a support sheet, a support frame, or the like, and is not specifically limited.

[0332] Specifically, the battery cell 20 is installed below the support member 11a and, together with the support member 11a, bears the force of the top of the housing 10 of the battery 100, thereby improving the rigidity of the top of the housing 10 of the battery 100.

[0333] In some embodiments, referring to Figures 10 and 20, the battery cells 20 are suspended on support members 11a.

[0334] The battery cells 20 being suspended from the support member 11a means that the battery cells 20 are installed vertically below the support member 11a and the weight of the battery cells 20 is supported by the support member 11a. Methods for suspending the battery cells 20 from the support member 11a include a method in which the battery cells 20 are directly bonded to the lower surface of the support member 11a, a method in which the battery cells 20 are connected to the support member 11a via fasteners and positioned below the support member 11a, and a method in which the battery cells 20 are hung on the support member 11a via a hook or the like and positioned below the support member 11a.

[0335] At this time, the battery cells 20 are suspended below the support member 11a, and the bottom cover 11c is located at the bottom of the housing 10. When performing maintenance on the inside of the battery 100, the battery cells 20 can be exposed by removing the bottom cover 11c, eliminating the need to remove the support member 11a, and making maintenance of the battery 100 easier. At the same time, when performing maintenance on the battery 100, the battery cells 20 can be attached to and detached from the support member 11a from below. In particular, when the support member 11a is subjected to force as at least part of the chassis of the vehicle 1000, the battery cells 20 can be attached and detached only from below the support member 11a, eliminating the need to remove the support member 11a, making maintenance of the battery 100 easier.

[0336] In some embodiments, the battery cells 20 are bonded to the support members 11a.

[0337] Specifically, the battery cells 20 and the support members 11a may be bonded together using an adhesive such as an epoxy resin adhesive or an acrylic ester adhesive, but there are no specific limitations on the type of adhesive. In this case, the battery cells 20 and the support members 11a are bonded together, which not only facilitates connection but also simplifies the structure of the battery 100.

[0338] FIG. 22 is a structural schematic diagram of a battery cell 20 in some embodiments of the present application.

[0339] In some embodiments, referring to FIG. 22 , the outer surface of the battery cell 20 facing the support member 11a is a first outer surface m1, and the battery cell 20 includes an electrode terminal 21a, and the electrode terminal 21a is disposed on an outer surface of the battery cell 20 other than the first outer surface m1.

[0340] As described above, the electrode terminals 21a are used to electrically connect with the electrode assemblies 23 inside the battery cells 20, and are components for outputting or inputting electrical energy to or from the battery cells 20. The electrode terminals 21a extend at least partially from the battery cells 20 to electrically connect with the outside. The series and parallel connections between the battery cells 20 are realized by connecting the respective electrode terminals 21a in series or parallel. The electrode terminals 21a are conductive and realize electrical transmission, and may be aluminum electrodes, copper electrodes, etc.

[0341] The electrode terminal 21a is disposed on an outer surface of the battery cell 20 other than the first outer surface m1. The first outer surface m1 faces the support member 11a and is generally a smooth surface, with no protruding or recessed structures such as the electrode terminal 21a or the liquid inlet hole. When the battery cell 20 is suspended from the support member 11a, the first outer surface m1 is the upward-facing outer surface of the battery cell 20. In a specific embodiment, the battery cell 20 includes the above-mentioned case 22 and end cover 21, which form an internal environment for the battery cell 20 to accommodate the electrode assembly 23. The end cover 21 is located at one end of the case 22, and the electrode terminal 21a is disposed on the end cover 21. In this case, any one outer surface of the case 22 can be the first outer surface m1 of the battery cell 20.

[0342] The electrode terminals 21a include a positive terminal and a negative terminal, and the positive terminal is used to electrically connect to a positive plate in the electrode assembly 23, and the negative terminal is used to electrically connect to a negative plate in the electrode assembly 23. It should be noted that the positive terminal and the negative terminal may be disposed on the same outer surface of the battery cell 20 (e.g., a rectangular battery cell), or may be disposed on two different outer surfaces of the battery cell 20 (e.g., a cylindrical battery cell). When the positive terminal and the negative terminal are disposed on two different outer surfaces of the battery cell 20, the first outer surface m1 is a surface of the battery cell 20 that is different from the two outer surfaces.

[0343] In addition to the battery cells 20, the battery 100 typically includes components such as a sampling harness that electrically connects each battery cell 20, a high-voltage harness, and a protective structure that protects the battery cells 20. When the electrode terminals 21a are disposed on a surface other than the first outer surface m1 of the battery cells 20 and components such as the sampling harness, high-voltage harness, and protective structure are disposed on the electrode terminals 21a, the components can be disposed in the space between the battery cells 20 and the structure of the body 11 other than the support member 11a (e.g., the space between the battery cells 20 and the bottom cover 11c and / or the space between the battery cells 20 and the inner surface of the body 11) without being restricted by the support member 11a, making the installation of the components easier. At the same time, because the first outer surface m1 is smooth, it can be bonded to the support member 11a, achieving seamless attachment between the battery cells 20 and the support member 11a. This eliminates the need to leave a space between the battery cells 20 and the support member 11a, thereby improving the space utilization rate of the battery 100.

[0344] In some embodiments, referring to FIG. 22, the battery cell 20 has a second outer surface m2 placed back to back with the first outer surface m1, and the electrode terminal 21a is disposed on the second outer surface m2.

[0345] The second outer surface m2 is an outer surface on which the battery cell 20 is placed back to back with the first outer surface m1, and when the battery cell 20 is suspended from the support member 11a, the second outer surface m2 faces the bottom cover 11c.

[0346] Furthermore, the battery cells 20 and the bottom cover 11c may be installed with a gap therebetween, which prevents external forces acting on the bottom cover 11c from being transmitted to the battery cells 20 and damaging the battery cells 20. In particular, when the battery 100 is attached to the bottom of the vehicle 1000 and the bottom cover 11c is located at the lowest point of the battery 100, stones and the like from the ground are likely to fly up to the bottom of the battery 100 while the vehicle 1000 is running and hit the bottom cover 11c. In this case, the buffer space can block the transmission of external forces to the battery cells 20 so that the battery cells 20 are not affected. When the battery cell 20 and the bottom cover 11c are spaced apart, a buffer space is provided between the second outer surface m2 and the bottom cover 11c, and the portion of the electrode terminal 21a extending from the battery cell 20 is located within this buffer space. Thus, the wire harness and connection sheet connected to the electrode terminal 21a can be disposed within the buffer space. At the same time, the buffer space also prevents the above-mentioned external force striking the bottom cover 11c from acting on the battery cell 20 and damaging the battery cell 20. Therefore, the buffer space not only blocks the effects of external forces but also allows for the layout of the wire harness and other components, achieving two-for-one benefits. Furthermore, the space utilization of the buffer space and the battery 100 is improved.

That is, the top of the housing 10 is used to form at least a part of the chassis of the vehicle body 200. In this way, the top of the housing 10 and the chassis of the vehicle body 200 are integrated into one body, and the space occupied by the gap between the conventional chassis and the battery 100 is divided into the battery 100, thereby increasing the space of the battery 100, which contributes to improving the energy of the battery 100 and further improving the driving range of the vehicle 100.

In this case, the battery 100 is suspended from the support member 11a, which improves the strength of the support member 11a and further improves the strength of the top of the battery cells 20, and when the support member 11a is used as a chassis, a certain force-bearing requirement can be met. At the same time, the electrode terminals 21a of the battery cells 20 are separated from the support member 11a, and the battery cells 20 can be directly attached to the support member 11a, eliminating the gap between the battery cells 20 and the support member 11a, and the saved gap can be used to increase the installation space of the battery cells 20, improving the energy of the battery 100 and further improving the driving range of the vehicle 1000.
