Description

[Technical Field]

[0001] FIELD OF THE INVENTION This application relates to the field of batteries, 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 entire vehicle.

[0003] A vehicle typically includes a body and a battery mounted on the body, but in related technologies, the battery is mounted on the body, leaving most of the battery exposed at the bottom of the body, and the wiring harness connecting the battery to the vehicle's electrical components (e.g., air conditioning, lights, power drive system, etc.) is also exposed, making it vulnerable to damage and adversely affecting the safety of the battery. Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, the present application provides a battery and a power consuming device that aims to improve the safety of the battery.

[0005] In a first aspect, the present application provides a housing for a battery having a housing cavity for housing a single battery and a top surface facing away from the housing cavity, the top surface of the housing being positioned so as to contact an external device to which the battery is attached, and the outer wall of the housing being configured with a wire-passing section positioned below the top surface of the housing and having a wire-passing space formed therein for passing a wire harness.

[0006] In the technical proposal of the present application, a wiring section is formed on the outer wall of the housing, and the wire harness is routed through the wiring space formed by the wiring section. This prevents the wire harness from being pressed and deformed when the vehicle is pressed from the outside, which would cause unnecessary safety risks, and effectively protects the wire harness.

[0007] In some embodiments, the wiring portion is disposed on a side wall of the housing that is adjacent to the top surface of the housing itself, which increases the side operation space of the housing and makes it easier to arrange the wiring harness.

[0008] In some embodiments, the wiring sections are disposed on two side walls adjacent to the top surface of the housing and facing away from each other. In this case, the wiring sections may be disposed symmetrically opposite each other in the first direction or opposite each other in the second direction, and the wire harness may be routed through both sides of the housing in the first direction at the same time, or through both sides of the housing in the second direction at the same time. This allows for a symmetrical arrangement of the wire harness, which not only achieves a more aesthetically pleasing wiring arrangement but also contributes to the balance of the vehicle weight.

[0009] In some embodiments, the wiring portion includes a wiring groove formed in the outer wall of the housing in a concave shape toward the receiving cavity. In this case, the wiring groove has an opening, which makes it easier to pass the wire harness through. Furthermore, since the concave wiring groove is configured as the wiring portion, there is no need to add a separate structure to form a wiring space, making the structure of the housing simpler and less costly.

[0010] In some embodiments, the housing includes a main body forming a storage cavity and a side beam, a top of the main body forming at least a portion of the top of the housing, the battery being attached to an external device via the top of the housing, and the main body having a circumferential side wall disposed around an outer edge of the top of the main body. The side beam is disposed on the circumferential side wall. In this case, the side beam is provided on the side peripheral wall of the main body, which can enhance the lateral structural strength of the main body and further improve the lateral pressure resistance of the housing. When the battery is applied to a vehicle, the lateral pressure resistance of the vehicle can be improved, thereby improving the safety of the vehicle.

[0011] In some embodiments, the side beams are configured to form a wire-running section, where the wire-running section is formed in the side beams, i.e., the side beams have space for wire-running, which can reduce the weight of the side beams and allow wire-running, killing two birds with one stone.

[0012] In some embodiments, the side beams include upper and lower arm beams spaced apart from each other and connected to the main body, the upper and lower arm beams together forming a wire-passing section with a wire-passing space. In this case, in a structure in which the main body is reinforced with the upper and lower arm beams, the upper and lower arm beams are separately arranged, so that the impact force received by the housing can be dispersed and the external force received by each part of the housing can be made relatively uniform. At the same time, by arranging the upper and lower arm beams spaced apart from each other from above, the sub-beams can withstand pressure in the front-rear or left-right directions of the vehicle, which is more suited to the actual usage conditions of the vehicle, and can form a wire-passing space like a wire-passing groove, making wiring easier.

[0013] In some embodiments, the top of the side beam is configured with a mounting portion, and the battery is attached to an external device via the mounting portion. The mounting portion is a dedicated structure provided on the top of the housing for connection to a connector (e.g., a bolt, rivet, etc.) of the external device, one end of the connector can be connected to the mounting portion, and the other end of the connector can be connected to the external device to fixedly connect the battery to the external device. In this case, providing the mounting portion on the side beam increases the operating space when attaching the housing to the external device, making it more convenient.

[0014] In some embodiments, the mounting portion includes at least one mounting hole on the top of the side beam, which can be drilled on the top surface of the housing, allowing a connecting material to pass through the mounting hole and, together with the structure in which the mounting hole is opened, achieve fixation and connect the external device to the top surface of the housing via the connecting material.

[0015] In some embodiments, the housing also includes a seal disposed on the top of the body for sealingly connecting with an external device, whereby the battery housing and the external device achieve a sealed connection through the seal, ensuring a reliable seal and low cost.

[0016] In some embodiments, the main body includes a carrier and a frame that encloses a cavity with at least a top end of the carrier penetrating therethrough, the carrier covering the top end of the cavity, and the carrier and frame together enclosing and forming at least a partial accommodating cavity. The side beams are installed on the circumferential side walls defined by the frame. The cavity formed by the frame primarily constitutes the accommodating cavity of the housing, and the accommodating cavity has a certain height to accommodate multiple cells. Since the frame also has a certain height, the circumferential side wall area of ​​the frame is large. The side beams are installed on the circumferential side walls defined by the frame, allowing for greater flexibility in the mounting method, mounting area, and arrangement of the side beams.

[0017] In some embodiments, the side beams are fixedly connected to the frame or are integrally molded. Integrating the side beams and the frame can reduce the assembly process of the housing and speed up the manufacturing process of the housing. Integrating the side beams and the frame can simplify the molding process of the side beams and the frame and reduce the manufacturing cost of the housing.

[0018] In a second aspect, the present application also provides a battery including the above-described housing and a single battery housed within the housing.

[0019] In some embodiments, the main body includes a carrier positioned on the top of the housing and defining a storage cavity, and the battery unit is placed on the carrier. The battery unit is disposed below the carrier and shares the force of the top of the battery housing with the carrier, thereby increasing the rigidity of the top of the battery housing.

[0020] In some embodiments, the battery unit is suspended from the carrier, the battery unit is suspended below the carrier, and the bottom cover is located at the bottom of the housing, so that when repairing the inside of the battery, the bottom cover can be removed to expose the battery unit without removing the carrier, making battery maintenance more convenient. On the other hand, when repairing the battery, the battery unit can be attached to and detached from the carrier from below, and especially when the carrier is subjected to force as at least a part of the chassis of the vehicle, the battery unit can be simply attached and detached from below the carrier without removing the carrier, making battery repair easier.

[0021] In some embodiments, the outer surface of the battery unit facing the carrier is a first outer surface, and the battery unit includes electrode terminals located on an outer surface of the battery unit other than the first outer surface. In this case, the electrode terminals are located on an outer surface of the battery unit other than the first outer surface, and various components connecting the electrode terminals (e.g., a sampling harness, a high-voltage harness, a guard structure, etc.) can be arranged through the space between the battery unit and the bottom cover and / or the space between the battery unit and the inner surface of the main body, making the arrangement of each component more convenient. In addition, by connecting the first outer surface, on which the electrode terminals are not provided, to the carrier, close contact between the battery unit and the carrier can be achieved, thereby saving space between the battery unit and the carrier and improving the space utilization rate of the battery.

[0022] In some embodiments, the battery unit has a second outer surface disposed opposite the first outer surface, and the electrode terminals are disposed on the second outer surface. In this case, a buffer space is formed between the second outer surface and the bottom cover, where the electrode terminals protrude from the battery unit. A wire harness or a connecting piece connected to the electrode terminals can be disposed within the buffer space. The buffer space also prevents damage to the battery unit caused by an external force hitting the bottom cover. This kills two birds with one stone: the buffer space not only blocks the effects of external forces, but also allows for the layout of the wire harness, etc.

[0023] In a third aspect, the present application also provides a power consuming device comprising a battery as described above for use in providing electrical energy to the power consuming device.

[0024] In some embodiments, the power consumption device includes a vehicle, and the battery is located at the bottom of the vehicle body, whereby the battery does not occupy space inside the vehicle body and can contribute to reducing the volume and weight of the vehicle body.

[0025] In some embodiments, the battery is connected to the vehicle body through the top of the housing, and the top of the housing is arranged to form at least a part of the chassis of the vehicle body, thereby dividing the space occupied by the gap between the conventional chassis and the battery into a space that expands the battery within the battery, thereby improving the energy of the battery and increasing the driving range of the vehicle.

[0036] Currently, the development of the market situation shows that the applications of batteries are becoming increasingly widespread. Batteries are used not only in energy storage and power supply systems for hydroelectric, thermal, wind, and solar power plants, but also in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment, aviation, and space. As the application fields of batteries expand, market demand is also continuing to grow.

[0037] The inventors note that in the related art, in order to improve the passenger space of a vehicle, the battery is mounted at the bottom of the vehicle, in which case at least a part of the battery is exposed to the outside, and the harness connecting the battery to the power consuming components of the vehicle must pass through the outside of the battery, and the exposed part is easily damaged, which endangers the safety of the battery.

[0038] In order to improve the safety of the battery, the applicant's research has shown that a wiring space can be formed outside the battery casing for the wire harness to pass through, and the wiring space can be used to protect the wire harness from damage caused by external forces.

[0039] Based on the above considerations, the inventors conducted extensive research to improve the safety of batteries and came up with a battery housing having a housing cavity for housing a single battery and a top surface facing away from the housing cavity, the top surface of the housing being positioned so as to contact an external device to which the battery is attached. The outer wall of the housing is provided with a wire-running section positioned below the top surface of the housing and having a wire-running space formed therein for passing a wire harness. By forming the wire-running section on the outer wall of the housing and passing the wire harness through the wire-running space formed by the wire-running section, unnecessary safety risks caused by the wire harness being pressed and deformed when the vehicle is pressed from the outside can be avoided, and the wire harness can be effectively protected.

[0040] The batteries disclosed in the embodiments of the present application can be used in power consumption devices such as, but not limited to, vehicles, ships, and aircraft. A power supply system including the batteries disclosed in the present application can be used to configure the power consumption device. The mounting structure of the present application is a structure for mounting a battery in a power consumption device.

[0041] 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 computer, an electric toy, an electric tool, a battery car, an electric vehicle, a steamship, a spacecraft, etc. Here, the electric toy may include a stationary or mobile electric toy such as a game console, an electric vehicle toy, an electric steamship toy, an electric airplane toy, etc., and the spacecraft may include an airplane, a rocket, a space shuttle, a spaceship, etc.

[0042] In the following embodiment, for convenience of explanation, a case will be described in which one of the power consuming devices according to an embodiment of the present application is a vehicle 1000 as an example.

[0043] Referring to FIG. 1, FIG. 1 is a schematic diagram showing the structure of a vehicle 1000 provided by some embodiments of the present application. The vehicle 1000 can be a gasoline-powered vehicle, a gas-powered vehicle, or a new energy vehicle, and the new energy vehicle can be an electric vehicle, a hybrid vehicle, an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000. When the battery 100 is used in a vehicle, the battery 100 can be installed at the bottom, head, or rear of the vehicle 1000. The battery 100 can be used to supply power to the vehicle 1000, for example, the battery 100 can be used as an operating power source for the vehicle 1000. The vehicle 1000 can also include a controller and a motor, and the controller controls the battery 1000 to supply power to the motor, for example, for starting the vehicle 1000, navigation, and operating power needs during driving.

[0044] In some embodiments of the present application, the battery 100 can function not only as an operating power source for the vehicle 1000, but also as a drive power source for the vehicle 1000, providing driving power for the vehicle 1000 in place of or partially in place of gasoline or natural gas.

[0045] Referring to Fig. 2, Fig. 2 is a schematic diagram showing the structure of a vehicle 1000 provided according to some embodiments of the present application. A battery unit 20 is the smallest unit constituting the battery 100. As shown in Fig. 2, the battery unit 20 includes an end cap 21, a housing 22, an electrode assembly 23, and other functional members.

[0046] The end cap 21 is a member that covers the opening of the housing 22 to isolate the internal environment of the battery unit 20 from the external environment. The shape of the end cap 21 can be adapted to the shape of the housing 22 and fitted to the housing 22, although this is not a limitation. Alternatively, the end cap 21 may be formed of a material with a certain hardness and strength (e.g., an aluminum alloy), which makes the end cap 21 less likely to deform during a pressure collision, thereby enhancing the structural strength of the battery unit 20 and improving safety. The end cap 21 may be provided with functional components such as electrode terminals 21a. The electrode terminals 21a can be used for electrical connection with the electrode assembly 23 for outputting or inputting electrical energy to or from the battery unit 20. In some embodiments, the end cap 21 may be provided with a pressure relief mechanism for releasing internal pressure when the internal pressure or temperature of the battery unit 20 reaches a threshold. The end cap 21 may be made of various materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, or plastic, but the embodiments of the present application do not impose any particular limitations thereon. In some embodiments, the inside of the end cap 21 may be provided with an insulating member that may be used to isolate the electrical connection 11a2 in the housing 22 from the end cap 21 to reduce the risk of short circuits. The insulating member may be, for example, plastic, rubber, etc.

[0047] The housing 22 is an assembly that fits the end cap 21 to form an internal environment of the battery unit 20. The formed internal environment can be used to accommodate the electrode assembly 23, electrolyte, and other components. The housing 22 and the end cap 21 may be separate components, or an opening may be formed in the housing 22, and the end cap 21 may cover the opening to form the internal environment of the battery unit 20. The end cap 21 and the housing 22 may be integrated, or, specifically, the end cap 21 and the housing 22 may form a common connection surface before other components are inserted into the housing, and the end cap 21 may be covered by the housing 22 when the interior of the housing 22 needs to be packaged. The housing 22 may have a variety of shapes and sizes, such as a rectangular parallelepiped, cylindrical, or hexagonal prism. Specifically, the shape of the housing 22 can be determined depending on the specific shape and size of the electrode assembly 23. The material of the housing 22 may be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., but the embodiment of the present application does not impose any particular limitation thereon.

[0048] The electrode assembly 23 is a component where an electrochemical reaction occurs in the battery unit 20. One or more electrode assemblies 23 can be included within the housing 22. The electrode assembly 23 is typically formed by winding or stacking a positive electrode sheet and a negative electrode sheet, with a separator typically being provided between the positive and negative electrode sheets. The portions of the positive and negative electrode sheets containing active material constitute the main body 11 of the electrode assembly 23, while the portions of the positive and negative electrode sheets not containing active material constitute the main body 11, respectively. The positive and negative electrode lugs may be commonly located at one end of the main body 11, or may be located at both ends of the main body 11. During charging and discharging of the battery, the positive and negative electrode active materials react with the electrolyte, and the electrode lugs are connected to the electrode terminal 21a, forming a current loop.

[0049] FIG. 3 is an exploded schematic view of a battery 100 provided according to some embodiments of the present application, the battery 100 including a battery unit 20 and a housing 10 having a housing cavity s for housing the battery unit 20.

[0050] The battery 100 may include multiple battery units 20, and the multiple battery units 20 may be connected in series, in parallel, or intermixed. Intermixed connection refers to the multiple battery units 20 being connected in series or in parallel. The multiple battery units 20 may be connected in series, in parallel, or intermixed with each other, and then the entire battery unit 20 is housed within the housing 10. Of course, the battery 100 may also be configured as a battery module formed by connecting multiple battery units 20 in series, in parallel, or intermixed, and then housed within the housing 10 as a whole battery module formed by connecting multiple battery modules in series, in parallel, or intermixed. The battery 100 may also include other structures, such as a junction member for achieving electrical connection between the multiple battery units 20. Each battery unit 20 may be a secondary battery or a primary battery, and may be, but is not limited to, a lithium-sulfur battery, a sodium ion battery, or a magnesium ion battery. The battery unit 20 may be cylindrical, flat, rectangular, or have other shapes.

[0051] The housing 10 may have a variety of shapes, such as a cylindrical shape or a rectangular parallelepiped shape, and the specific configuration of the housing 10 can take on a variety of structural forms.

[0052] According to some embodiments of the present application, referring to FIG. 3 , the present application provides a housing 10 for a battery 200, the housing 10 having a housing cavity s for housing a single battery 20. The housing 10 provides a housing space for the single battery 20, and the housing can have a variety of structures. In some embodiments (as shown in FIG. 3 ), the housing includes a first portion 10A and a second portion 10B that are mutually covered, and the first portion 10A and the second portion 10B together can define a housing space for housing the single battery. The second portion 10A can have a hollow structure with one end open, and the first portion 10A can have a plate-like structure with the open side of the second portion covered so as to define the housing space together with the second portion 10B. Alternatively, both the first portion 10A and the second portion 10B can have a hollow structure with one end open, and the open side of the first portion 10A covers the open side of the second portion 10B. Of course, the housing 10 formed by the first portion 10A and the second portion 10B may have a variety of shapes, such as a cylindrical shape or a rectangular parallelepiped shape.

[0053] Fig. 4 is another exploded view of the structure of battery 100 in some embodiments of the present application. Fig. 5 is an enlarged view of A in Fig. 4. Fig. 6 is a schematic view showing the structure of a portion of battery 100 in some embodiments of the present application. Fig. 7 is an enlarged view of portion B in the structure shown in Fig. 6, Fig. 8 is a plan view of the structure shown in Fig. 6, Fig. 9 is a side view of the structure shown in Fig. 6, and Fig. 10 is a cross-sectional view of portion CC in the structure shown in Fig. 9.

[0054] In some embodiments, referring to FIG. 4, the battery 100 is attached to an external device through the top of the housing 10 .

[0055] The top surface of the housing 10 includes a top surface h of the housing 10 and other structures provided on the top surface h of the housing 10. The top surface h of the housing 10 is the vertically upper surface of the housing 10 when in use. Other structures provided on the top surface h of the housing 10 include, but are not limited to, a connecting member (e.g., bolt, rivet, etc.) that connects the top surface h of the housing 10 to an external device, and a sealing structure (e.g., seal strip, etc.) that seals the housing 10 to an external device.

[0056] The external device is a device for mounting the housing 10. The external device may be a local structure for mounting the housing 10 among the above-mentioned power consuming devices, or the remaining structure of the power consuming device that forms the power consuming device together with the battery 100. Taking a vehicle 1000 as an example of the power consuming device, the external device may be the body 200 of the vehicle 1000, and the battery 100 may be mounted to the bottom of the body 200 and attached to the body 200 via its top.

[0057] In this case, the battery 100 is attached to the external device via the top of the housing 10, and the housing 10 is positioned at the bottom of the external device, while the structure of the connection between the housing 10 and the external device is miniaturized, resulting in a compact design at low cost.

[0058] Of course, in other embodiments, the battery 100 may be attached to an external device via a location such as the bottom or side of the housing 10 .

[0059] In some embodiments, referring to FIG. 4, the housing 10 includes a body 11 that encloses and defines a receiving cavity s.

[0060] The main body 11 may be a one-piece structure or may be formed by combining multiple parts. As can be understood, the main body 11 is a hollow shell structure that surrounds itself to form the storage cavity s. Specifically, the main body 11 may be formed by combining a first sub-part (not shown) and a second sub-part (not shown). In one example, the first sub-part surrounds the storage cavity s with one open end, and the second sub-part covers the opening of the storage cavity s. In another example, the first sub-part surrounds a first space with one open end, and the second sub-part surrounds a second space with one open end, so that the openings of both the first and second sub-parts are covered, forming the storage cavity s consisting of the first and second spaces. The first and second sub-parts can be welded, fastened, or joined together. The first and second sub-parts may be made of plastic, metal, or other materials.

[0061] In some embodiments, referring to FIG. 4, the top of body 11 forms at least a portion of the top of housing 10.

[0062] The top of the main body 11 is a structure located at the topmost position in the vertical direction of the main body 11, and the topmost position of the main body 11 is the topmost position of the housing 10, and 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 also has a structure in which other parts, such as the side beams 13 described in detail below, do not participate in defining the storage cavity s.

[0063] When the battery 100 is attached to an external device via the top surface of the housing 10, the top surface of the main body 11 is also located at the position of the battery 100 closest to the external device, and the distance between the top surface of the main body 11 and the external device is the distance between the highest point of the top surface of the main body 11 and the external device located vertically above it.

[0064] As can be seen, with reference to Figure 6, the body 11 has a circumferential sidewall n disposed around the outer edge of its top.

[0065] The main body 11 has a top portion located at the uppermost position in the vertical direction, and naturally has a bottom portion located at the lowermost position, of which the bottom portion may be a bottom-to-bottom structure or may be open.

[0066] The outer surface of the structure sandwiched between the top and bottom, facing away from the storage cavity s, forms a circumferential sidewall n, and the extension direction of the plane in which the circumferential sidewall n is located intersects with the plane in which the top is located. The circumferential sidewall n may be annular, rectangular, or the like, formed by a plurality of wall segments connected in front and behind, as will be described in detail below.

[0067] As can be seen, with reference to FIG. 6, the housing 10 further has a top surface h facing the receiving cavity s.

[0068] The top surface h of the housing 10 is located on the surface facing away from the storage cavity s at the top of the housing 10, and when the battery 100 is connected to an external device via the top of the housing 10, the top surface h is positioned facing the external device, forming the position of the battery 100 that is closest to the external device.

[0069] In some embodiments, referring to FIG. 6, the top surface h of the housing 10 is positioned to contact an external device (not shown) to which the battery 100 is attached.

[0070] The battery 100 is attached to the external device via the top of the housing 10, and one surface of the housing 10 facing away from the receiving cavity s is in contact with and tightly adhered to the external device. Therefore, compared to a system in which the top surface h of the housing 10 is positioned so as not to come into contact with the external device, the structure of the connection between the housing 10 and the external device is smaller, and is more compact at lower cost.

[0071] In some embodiments, referring to FIG. 6, the top of the housing 10 is configured with a mounting portion 13a3, and the battery 100 is attached to an external device via the mounting portion 13a3.

[0072] Mounting portion 13a3 is part of the top of housing 10 and is not involved in defining storage cavity s. Mounting portion 13a3 is a dedicated structure provided on the top of housing 10 for connection to a connecting member (e.g., a bolt, rivet, etc.) of an external device, one end of the connecting member can be connected to mounting portion 13a3, and the other end of the connecting member is connected to the external device, thereby fixedly connecting battery 100 to the external device. As can be understood, the top of main body 11 is at least a part of the top of housing 10, and mounting portion 13a3 may be provided on the top of main body 11 or on another structure that constitutes the top of housing 10 (the top of side beam 13, which will be described later).

[0073] When the battery 100 is attached to an external device via the attachment 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 ensuring a compact connection structure between the housing 10 and the external device.

[0074] The mounting portion 13a3 itself may have a connecting function (e.g., a hanging ring, etc.), or a corresponding connecting member (e.g., a hook, etc.) may be provided on the external device to directly connect with the mounting portion 13a3. In other embodiments, the mounting portion 13a3 and the external device may be directly connected without providing a connecting member by other methods including, but not limited to, fastening, plugging, screw joining, riveting, welding, adhesive, etc., and this application is not particularly limited thereto.

[0075] In some embodiments, referring to FIG. 6, the mounting portion 13a3 includes at least one mounting hole k1 provided on the top of the housing 10.

[0076] Mounting holes k1 can be formed on the top surface of the housing 10 by drilling, and openings communicating with the hole and both ends of the hole are provided inside all of the mounting holes k1. The openings communicating with the hole and both ends of the hole allow the connecting material to pass through the mounting hole, which, together with the structure in which the mounting holes k1 are opened, achieves fixation and connects the external device to the top surface of the housing 10 via the connecting material.

[0077] The connecting piece may be a rivet, and a fixing hole 11c3 is provided at the position of the external device corresponding to the mounting hole k1, and the rivet is passed through the fixing hole 11c3 and the mounting hole k1, and then the two are fixed with a nut. The connecting member may be a screw, and the mounting hole k1 may be a threaded hole, and the screw may be passed through the mounting hole k1 to connect to the housing 10.

[0078] Specifically, all of the mounting holes k1 can be extended in the vertical direction to vertically fix the battery 100 to the bottom of the external device. As can be seen, in order to achieve a stable connection between the top surface of the housing 10 and the external device and to achieve uniformity in the force received by both, factors such as the installation positions and installation distances of all of the mounting holes k1 can be controlled, as described in detail below.

[0079] As can be understood, the mounting portion 13a3 may have other mounting structures such as hooks in addition to the mounting hole k1.

[0080] In some embodiments, referring to Figures 4 and 6, the main body 11 includes a carrier 11a and a frame 11b having at least a top end thereof extending therethrough to form an enclosed cavity, the carrier 11a covering the top end of the cavity, and the carrier 11a and the frame 11b enclosing and forming at least a partial receiving cavity s.

[0081] The frame 11b is surrounded by the carrier 11a to form a cavity with at least its top end penetrating through it, and the carrier 11a covers the top of the cavity, i.e., the carrier 11a is located at the top of the housing 10 to define the receiving cavity s. The frame 11b and the carrier 11a may be made of the same material, such as aluminum alloy, copper alloy, steel, or plastic. Of course, the frame 11b, the carrier 11a, and the bottom cover 11c may be made of different materials, and there is no specific limitation. In vertical orthogonal projection, the frame 11b may be rectangular, circular, polygonal, or the like, and there is no specific limitation. The carrier 11a may be a carrier plate, carrier sheet, carrier block, or the like.

[0082] The entire top surface h1 of the main body 11 may be formed by the top surface of the carrier 11a so that the entire frame 11b is located below the carrier 11a. The top surface h1 of the main body 11 may be formed together with the top surfaces of the carrier 11a and the frame 11b, in which case the carrier 11a is located inside the frame 11b, and the top surfaces of the carrier 11a and the frame 11b may or may not be coplanar.

[0083] The carrier 11a is fixedly connected to the frame 11b or is molded integrally with the frame 11b. The carrier 11a and the frame 11b are integrally molded by injection molding, die casting, forging, cold pressing, hot pressing, etc. The carrier 11a and the frame 11b can be fixedly joined by fastening with a fastener, engagement with an engaging structure, welding, adhesive, heat fusion bonding, etc.

[0084] The circumferential sidewall n of the body 11 is formed mainly from the circumferential sidewall n of the frame 11b, which is the outer surface located around the carrier 11a and remote from the cavity it defines.

[0085] In some embodiments, referring to FIGS. 4 and 5, the main body 11 further includes a bottom cover 11c that, together with the carrier 11a and the frame 11b, surrounds and forms a housing cavity s that houses the battery unit 20.

[0086] As can be seen, the cavity in the frame 11b also penetrates to the bottom of the frame 11b, and the bottom cover 11c covers the bottom of the frame 11b, forming the receiving cavity s of the housing 10 together with the frame 11b and the carrier 11a.

[0087] Specifically, the bottom cover 11c may have a plate-like structure, a block-like structure, or the like, but is not limited to these, and may also have a flat plate-like, curved plate-like, or the like, but is not specifically limited to these. When the battery unit 20 is located in the accommodating cavity s, the battery unit 20 may be disposed on the bottom cover 11c and / or the carrier 11a and / or the frame 11b.

[0088] The bottom cover 11c and the frame 11b can be fixed to each other by welding, heat fusion, adhesive bonding, fastening, engagement, etc. Here, "fastened connection" refers to a connection using the fastening pieces 11c4, which include parts such as bolts, plugs, rivets, pins, and screws. Here, "engagement" refers to fastening by an engagement structure. For example, the bottom cover 11c has an engagement hook, and the frame 11b has an engagement opening, and when the engagement hook engages with the engagement opening, the bottom cover 11c and the frame 11b are engaged and fixed. Of course, the connection method between the bottom cover 11c and the frame 11b is not limited to this, and is not covered by this application.

[0089] In this case, the frame 11b is used as a base, and the carrier 11a and bottom cover 11c are connected to both vertical ends of the frame 11b to form a cavity s for accommodating the battery 100, so the structure of the main body 11 is relatively simple.

[0090] In some embodiments, referring to Figures 4 and 5, the bottom cover 11c has a cover portion 11c1 that defines the storage cavity s, an attachment portion 11c2 that is surrounded by and connected to the edge of the cover portion 11c1, and an attachment portion 11c2 that is connected to the frame 11b.

[0091] The lid portion 11c1 defines the receiving cavity s, meaning that the lid portion 11c1, together with the carrier 11a and the frame 11b, surrounds and forms the receiving cavity s, and the mounting portion 11c2 is connected to the frame 11b without being involved in defining the receiving cavity s. The lid portion 11c1 may be a plate-shaped part, a block-shaped part, a flat part, a curved plate-shaped part, or the like, and is not specifically limited. As can be seen from FIGS. 4 and 5, the mounting portion 11c2 being surrounded by the edge of the lid portion 11c1 means that the mounting portion 11c2 is connected along the edge of the lid portion 11c1, with the beginning and end of the mounting portion 11c2 being closed. The mounting portion 11c2 has a certain width when projected vertically, providing an appropriate contact area with the frame 11b, facilitating positioning and attachment of the mounting portion 11c2 to the frame 11b.

[0092] The lid portion 11c1 and the mounting portion 11c2 may be integrally molded. If the bottom lid 11c is made of metal (e.g., aluminum, iron, stainless steel, etc.), the lid portion 11c1 and the mounting portion 11c2 may be integrally molded by die casting, forging, hot pressing, cold pressing, etc. If the bottom lid 11c is made of plastic (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 also be connected after being molded separately. If the lid portion 11c1 and the mounting portion 11c2 are made of metal, the lid portion 11c1 and the mounting portion 11c2 may be welded or bonded. If the lid portion 11c1 and the mounting portion 11c2 are made of plastic, the lid portion 11c1 and the mounting portion 11c2 may be bonded. Of course, the cover portion 11c1 and the attachment portion 11c2 may be fixed and joined by other methods such as engagement or riveting.

[0093] The lid portion 11c1 and the mounting portion 11c2 may be located in the same plane. Specifically, selectively, both surfaces of the lid portion 11c1 and the mounting portion 11c2 facing the carrier 11a are located in the same plane, and / or both surfaces of the lid portion 11c1 and the mounting portion 11c2 facing away from the carrier 11a are located in the same plane. When both surfaces of the lid portion 11c1 and the mounting portion 11c2 facing toward the carrier 11a and both surfaces facing away from the carrier 11a are located in the same plane, the lid portion 11c1 and the mounting portion 11c2 can form a single flat bottom lid 11c.

[0094] 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 carrier 11a relative to the mounting portion 11c2, or the lid portion 11c1 may protrude away from the carrier 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 be the same or different and are not specifically limited.

[0095] In this case, the bottom cover 11c defines the accommodation cavity s via the cover portion 11c1 and is connected to the frame 11b via the attachment portion 11c2, so that the structure is clear and attachment is easy.

[0096] As can be understood, when bottom cover 11c is detachably connected to frame 11b, bottom cover 11c is detachably connected to frame 11b via attachment portion 11c2, i.e., attachment portion 11c2 is detachably connected to frame 11b. The method of detachably connecting attachment portion 11c2 to frame 11b simply requires that the portion of bottom cover 11c that is detachably connected to frame 11b be designated attachment portion 11c2.

[0097] In some embodiments, the mounting portion 11c2 is removably connected to the frame 11b.

[0098] Specifically, bottom cover 11c further includes a fixing hole 11c3 provided in mounting portion 11c2, and fixing device 11c4 passes through fixing hole 11c3 of mounting portion 11c2 and is fastened to frame 11b. Fixing hole 11c3 is a through-hole that passes vertically through mounting portion 11c2, and specifically, fixing hole 11c3 may be a smooth through-hole (for example, when fixing device 11c4 is a rivet), a threaded through-hole (for example, when fixing device 11c4 is a screw), or another type of through-hole (such as a hexagonal hole, square hole, or waist hole). The specific shape of fixing hole 11c3 is determined by the specific shape and specific setting method of fixing device 11c4, and will not be described here.

[0099] In some embodiments, referring to FIGS. 6, 8 and 9, the housing 10 includes a side beam 13 provided on a circumferential side wall n of the main body 11.

[0100] The side beams 13 are beam structures provided on the peripheral 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 may be integrally connected to the side beams 13 to form an integrated unit, or may be connected to the main body 11 by an assembly method to form an integrated unit. The integral connection method includes, but is not limited to, welding, integral molding, fusion, etc. The assembly connection method includes, but is not limited to, engagement, fastening connection, etc.

[0101] The side beams 13 may be arranged on the entire circumferential side wall n of the main body 11, or may be arranged on only a portion of the circumferential side wall n of the main body 11. Without being limited thereto, by installing the side beams 13 around the circumferential side wall n of the main body 11, the strength of the main body 11 can be reinforced from multiple side directions of the main body 11. Specifically, the side beams 13 are provided continuously or intermittently around the circumferential side wall n of the main body 11. When the side beams 13 are installed continuously, they can be annular beams, and when installed intermittently, they can include multiple beam portions arranged at intervals around the circumferential side wall n of the main body 11.

[0102] In some practical application scenarios, the housing 10 is used for the battery 100, the battery 100 is applied to the vehicle 1000, and the top surface of the housing 10 is attached to the vehicle 1000, with the top surface of the housing 10 forming the chassis structure of the vehicle 1000. When the housing 10 for the battery 100 is used as the chassis of the vehicle 1000, the lateral structure of the housing 10 is susceptible to external impact (for example, a stone flying while the vehicle 1000 is moving strikes the lateral position of the housing 10, or the housing 10 is hit by another vehicle 1000 at the lateral position), and is thereby pushed out. In this case, side beams 13 are provided on the lateral walls of the main body 11, which can strengthen the lateral structural strength of the main body 11 and further improve the lateral pressure resistance of the housing 10, thereby improving the lateral pressure resistance of the vehicle 10 and, at the same time, improving the safety of the vehicle 1000.

[0103] As can be seen, when the body 11 includes the above-mentioned carrier 11a and frame 11b, the side beams 13 are mounted on the circumferential sidewall n defined by the frame 11b.

[0104] The cavity formed by the frame 11b mainly constitutes the receiving cavity s of the housing 10, and the receiving cavity s has a certain height to accommodate multiple battery units 20, so the frame 11b also has a certain height and the area of ​​the circumferential side wall n of the frame 11b is relatively large. In this case, the side beams 13 are installed 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.

[0105] Furthermore, in the embodiment, the side beams 13 are fixedly connected to the frame 11b or are integrally formed with the frame 11b. The side beams 13 and the frame 11b may be fixedly joined by welding, fusion, riveting, screwing, or the like, or may be integrally formed by integral processing (for example, pressing, die casting, or the like).

[0106] Molding the side beams 13 and the frame 11b integrally can reduce the assembly process of the housing 10 and speed up the manufacturing process of the housing 10. Fixedly connecting the side beams 13 and the frame 11b can simplify the molding process of the side beams 13 and the frame 11b and reduce the manufacturing cost of the housing 10.

[0107] 10 , in some embodiments, the side beam 13 includes at least two sub-beams 13a arranged sequentially at intervals along the circumferential side wall n. The sub-beams 13a are basic units that constitute the side beam 13, and by setting the positions of the sub-beams 13a, the position of the side beam 13 can be flexibly arranged on the circumferential side wall n of the main body 11.

[0108] 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, meaning that at least two sub-beams 13a form an encircling shape around the main body 11 spaced apart in the extension direction of the circumferential side wall n, reinforcing the strength of the main body 11 from multiple side directions of the main body 11.

[0109] The sub-beams 13a may have a variety of structures, and the structures of the sub-beams 13a may be the same or different. For example, the sub-beams 13a may be solid beams extending in one longitudinal direction. For example, the sub-beams 13a may be hollow beams extending in one longitudinal direction. The cross-sectional shape of each sub-beam 13a may be an H-shape, a U-shape, or another structural shape.

[0110] In this case, the side beam 13 is formed by combining a plurality of sub-beams 13a, which increases the degree of freedom in arranging the side beam 13, and at the time of installation, it is sufficient to install each sub-beam 13a one by one, which makes positioning at the time of installation easier and more labor-saving than an integral side beam 13.

[0111] In some embodiments, with continued reference to FIG. 10, at least one sub-beam 13a includes an upper arm beam 131 and a lower arm beam 132, both connected to the main body 11 and spaced apart from one another.

[0112] The up-down direction corresponds to the direction in which the top and bottom of the main body 11 are located; that is, the upper arm beam 131 is close to the top surface of the main body 11, and the lower arm beam 132 is close to the bottom surface of the main body 11. As can be seen, the upper arm beam 131 and the lower arm beam 132 both extend in the circumferential direction of the main body 11 and are in close contact with the circumferential side wall n of the main body 11. The upper arm beam 131 and the lower arm beam 132 are arranged at a distance from each other and are connected via the main body 11, and a hole passage can be formed between the two, and this hole passage can be used both as a structure for reducing weight and as a structure for passing wires through a wire harness.

[0113] In this case, in a structure in which the main body 11 is reinforced by the upper arm beam 131 and the lower arm beam 132, the upper arm beam 131 and the lower arm beam 132 are arranged separately, so that the impact force received by the housing 10 can be dispersed, and the external force received by each part of the housing 10 can be made relatively uniform. At the same time, by arranging the upper arm beam 131 and the lower arm beam 132 at a distance from each other above and below, the sub-beam 13a can withstand pressure in the front-to-rear or left-to-right directions of the vehicle 1000, and is more suited to the actual usage conditions of the vehicle 1000. Furthermore, by arranging the upper arm beam 131 and the lower arm beam 132 at a distance from each other, the weight of the housing 10 can be reduced and other functions can be realized.

[0114] In another embodiment, an intermediate beam (not shown) is provided between the upper arm beam 131 and the lower arm beam 132, and the intermediate beam is connected between the upper arm beam 131 and the lower arm beam 132, thereby further strengthening the structural strength of the sub-beam 13a and improving the lateral pressure resistance of the housing 10.

[0115] 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 refers to a beam having a hollow structure, i.e., a space that is not filled with any solid material. In this case, since the upper arm beam 131 and the lower arm beam 132 have a hollow beam structure, not only can the weight of the beam itself be reduced, but also, when the battery 100 formed with the housing 10 is applied to a power consuming device such as a vehicle 1000, the problem of increased energy consumption of the battery 100 itself due to its large weight can be reduced. Furthermore, the hollow beam structure can dissipate lateral pressure through its internal space, thereby reducing the degree of damage to the battery 100 when subjected to lateral pressure.

[0116] In some embodiments, referring to FIG. 6, the circumferential side wall n includes at least two spaced apart first wall segments n1, both extending along the first direction F1, and the at least two sub-beams 13a include two first sub-beams 13a1 arranged in each of the two first wall segments n1 and both extending in the first direction F1.

[0117] In some practical applications, when the battery 100 formed in the housing 10 is used in a vehicle 1000 and the top surface of the housing 10 forms the chassis of the vehicle 1000, the first direction F1 can correspond to the longitudinal direction of the vehicle 1000. First wall segments n1 of the circumferential side walls n of the main body 11 correspond to both the left and right circumferential side walls n of the battery 100. The first wall segments n1 extend in the first direction F1, i.e., the longitudinal direction of the vehicle 1000. The two first wall segments n1 are spaced apart in the lateral direction of the vehicle 1000. Each of the two first wall segments n1 is provided with a sub-beam 13a, and each sub-beam 13a has the same extension direction as the first wall segment n1.

[0118] The sub-beams 13a on each first wall segment n1 can have the same structure, ensuring consistent pressure resistance on both the left and right sides of the vehicle 1000. Furthermore, the sub-beams 13a in the first wall segment n1 include the upper arm beam 131 and the lower arm beam 132 described in the above-mentioned embodiment, and in this case, the high pressure resistance of the sub-beams 13a can compensate for the weak structure on both the left and right sides of the vehicle 1000, thereby strengthening the pressure resistance on both the left and right sides of the vehicle 1000 and improving the safety of the vehicle 1000.

[0119] In this case, by providing a sub-beam 13a in each first wall segment n1, the structural strength of each first wall segment n1 can be strengthened, and the pressing resistance of each first wall segment n1, i.e., the pressing resistance to the left and right of the vehicle 1000, can be improved.As can be seen, since each sub-beam 13a extends in the first direction F1, the bending resistance in the fore-and-aft direction of the vehicle 1000 is also improved.

[0120] 6, in some embodiments, the circumferential side wall n further includes two second wall segments n2 extending along a second direction F2 perpendicular to the first direction F1 and spaced apart from each other, and the two first wall segments n1 are alternately connected to the two second wall segments n2. The at least two sub-beams 13a further include two second sub-beams 13a2 disposed in the two second wall segments n2, respectively, and both extending in the first direction F1.

[0121] In practical applications, the second direction F2 can correspond to the left-right direction of the housing 10. In this case, the second wall segment n2 corresponds to the circumferential side walls n in both the front and rear directions of the battery 100. The second wall segment n2 extends in the second direction F2, i.e., the left-right direction of the vehicle 1000.

[0122] The sub-beams 13a on each second wall segment n2 may have the same structure, ensuring consistent pressure resistance on both the front and rear sides of the vehicle 1000. Furthermore, the sub-beams 13a of the first wall segment n1 may include only the upper arm beam 131 described in the above-described embodiment, which is installed close to the top of the body 11, and in this case, the sub-beams 13a have weak pressure resistance. This is because the vehicle 1000 is generally provided with pressure resistance structures such as bumpers in the front and rear directions. When the vehicle 1000 is pressed in the front and rear directions, the pressure resistance effect is mainly realized by the provided front and rear bumpers. In this case, the sub-beams 13a of the second wall segment n2 do not require much pressure resistance, so a relatively simple sub-beam 13a structure can be used, reducing the costs of the battery 100 and the vehicle 1000.

[0123] In this case, by providing a sub-beam 13a in each second wall segment n2, the structural strength of each second wall segment n2 can be strengthened, and the pressing resistance of each second wall segment n2, i.e., the pressing resistance of the vehicle 1000 in the left and right directions, can be improved.As can be seen, since each sub-beam 13a extends in the second direction F2, the bending resistance of the vehicle 1000 in the left and right directions can also be improved.

[0124] In some embodiments, with continued reference to FIG. 6, the side beam 13 includes at least two first sub-beams 13a1 and at least two second sub-beams 13a2, both installed 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.

[0125] In this case, the sub-beam 13a provided in the first wall segment n1 is the first sub-beam 13a1, and the sub-beam 13a provided in the second wall segment n2 is the second sub-beam 13a2. The two first sub-beams 13a1 can reinforce the pressing resistance force of the housing 10 in the left-right direction of the vehicle 1000, and the two second sub-beams 13a2 can reinforce the pressing resistance force of the housing 10 in the front-rear direction of the vehicle 1000, so that the sideward pressing resistance force of the vehicle 1000 can be improved overall, and the safety of the vehicle 1000 can be improved.

[0126] In some embodiments, with continued reference to FIG. 6, the top of the side beam 13 is configured with a mounting portion 13a3.

[0127] The above description of the mounting portion 13a3 can be referred to for a detailed description, so it will not be discussed here. By providing the mounting portion 13a3 on the top of the side beam 13, the housing 10 of the present application can be obtained by adding the side beam 13 based on the structure of the existing housing 10. This significantly reduces the cost of modifications. Furthermore, by providing the mounting portion 13a3 on the side beam 13, the side beam 13 does not define the receiving cavity s. This eliminates the need to consider the effect of the mounting portion 13a3 on the sealing performance of the receiving cavity s when providing the mounting portion 13a3, allowing for more flexible design. Furthermore, since the side beam 13 is located on the side edge of the housing 10, providing the mounting portion 13a3 on the side beam 13 increases the operating space when attaching the housing 10 to an external device, making it more convenient.

[0128] In some embodiments, the mounting portion 13a3 includes at least one mounting hole k1 provided at the top of the side beam 13.

[0129] The above description can be used as a reference for the explanation of the mounting hole k1, so it will not be explained here. The mounting hole k1 is provided at the top of the side beam 13, and it also has the beneficial effect of providing the mounting portion 13a3 at the top of the side beam 13, so it will not be explained here.

[0130] In some embodiments, the top surface h1 of the main body 11 is defined to form the top surface h of the housing 10 together with the top surface h2 of the side beam 13 .

[0131] The top surface h1 of the main body 11 is the outer surface of one side of the main body 11 located at the top and away from the receiving cavity s, and the top surface h2 of the side beam 13 is the outer surface of one side of the side beam 13 located at the 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 is the outer surface of one side of the upper arm beam 131 away from the lower arm beam 132.

[0132] 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 and formed together with the top surface h1 of the main body 11 and the top surface h2 of the side beams 13. In this case, the top surface h1 of the main body 11 and the top surface h2 of the side beams 13 can be arranged coplanarly, thereby increasing the contact area between the top surface h of the housing 10 and an external device, contributing to improved connection reliability between the housing 10 and the external device, and making the top surface structure of the housing 10 relatively flat, improving appearance. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beams 13 may not be coplanar.

[0133] 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 forming the side beam 13, and the sub-beams 13a are provided with mounting portions 13a3. Some or all of the sub-beams 13a may be provided with mounting portions 13a3. When some of the sub-beams 13a are provided with mounting portions 13a3, all of the symmetrically arranged sub-beams 13a are provided with mounting portions 13a3 to ensure uniformity of the force received by the mounting portions 13a3. The symmetrically arranged sub-beams 13a include the two first sub-beams 13a1 in the above embodiment, but may also include the two second sub-beams 13a2 in the above embodiment.

[0134] In some embodiments, referring to Figures 6 and 10, a wire-passing section 13a4 is configured on the outer wall of the housing 10, which is located below the top surface h of the housing 10 and forms a wire-passing space for passing a wire harness.

[0135] The outer wall of the housing 10 is an outer surface facing away from the inner surface that defines the storage cavity s within the housing 10. The wire-running portion 13a4 is located below the top surface of the housing 10, that is, the wire-running portion 13a4 is provided on the outer wall of the housing 10 that is located below the top surface h. The outer wall that is located below the top surface h of the housing 10 includes a bottom surface and a side wall that connects the top surface h and the bottom surface.

[0136] When the housing 10 includes only the main body 11, the side wall of the housing 10 can be the circumferential side wall n of the main body 11. When the housing 10 includes the main body 11 and the side beam 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 side beam 13 and the surface of the side beam 13 facing away from the main body 11.

[0137] The wire-passing portion 13a4 is located outside the accommodating cavity s and has a wire-passing space through which a wire harness that electrically connects the cell unit and the power consuming component passes. The specific form of the wire-passing space is not limited, and it is sufficient if it has a wire inlet for the wire harness to enter and a wire outlet for the wire harness to exit, and the wire inlet and wire outlet may be the same opening. The wire-passing space can be a wire-passing hole or a wire-passing groove k2.

[0138] Specifically, the wiring portion 13a4 may be provided on the circumferential outer wall of the housing 10, in which case the wire harness can be routed via the side surface of the housing 10, making wiring easier. Specifically, the wiring portion 13a4 may be provided on the bottom surface of the housing 10, in which case the wire harness can be routed via the bottom surface of the housing 10.

[0139] In this case, by forming a wire passage section 13a4 on the outer wall of the housing 10 and passing the wire harness through the wire passage space formed by the wire passage section 13a4, the wire harness can be effectively protected from being pressed and deformed when the vehicle 1000 is pressed from the outside, thereby preventing unnecessary safety risks from occurring.

[0140] In yet another 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.

[0141] The sidewalls are outer surfaces that connect the top surface h of the housing 10 to the bottom surface (the surface opposite the top surface h). The wire-running portion 13a4 may be provided on only some of the sidewalls of the housing 10. For example, the wire-running portion 13a4 may be provided on one or both sidewalls of the housing 10 in the first direction F1, or on one or both sidewalls of the housing 10 in the second direction F2. Of course, the wire-running portion 13a4 may be provided on all of the sidewalls of the housing 10.

[0142] In this case, the wiring portion 13a4 is arranged on the side wall of the housing 10, and the side operation space of the housing 10 is increased, so that the arrangement on the wire harness becomes easier.

[0143] In some embodiments, the wiring portions 13a4 are arranged on two side walls of the housing 10 that are adjacent to the top surface h and are opposite each other.

[0144] The two side walls of the housing 10 adjacent to the top surface h and facing each other include two side walls facing each other in the first direction F1 and two side walls facing each other in the second direction F2. In this case, the wire-running portions 13a4 may be arranged symmetrically opposite each other in the first direction F1 or may be arranged opposite each other in the second direction F2, and the wire harness may be routed simultaneously 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 allows for a more elegant wiring arrangement and also contributes to the balance of the vehicle weight 1000.

[0145] Furthermore, the wire-running portions 13a4 are provided on both side walls of the housing 10 in the second direction F2, i.e., on both side walls of the housing 10 corresponding to the left-right direction of the vehicle 1000. Since the various electric drive systems (for supplying power to move the vehicle 1000 forward) in the vehicle 1000 are mainly arranged on the front or rear side, the wire harness connects the battery 100 and the electric drive systems mainly in the fore-and-aft direction of the vehicle 1000, and arranging the wire-running portions 13a4 in this manner makes it easier to run the wire harness.

[0146] In one specific embodiment, referring to FIGS. 6 and 10, the wire-passing portion 13a4 includes a wire-passing groove k2 formed in the outer wall of the housing 10 in a concave shape toward the receiving cavity s.

[0147] As can be seen, the wire-passing groove k2 is recessed toward the accommodating cavity s to form a wire-passing space having one opening, which faces the groove bottom of the wire-passing groove k2. The wire-passing groove k2 is recessed toward the accommodating cavity s and may have a wire inlet and a wire outlet. Specifically, the wire inlet of the wire-passing groove k2 may be an opening at one end of the wire-passing groove k2 in the extension direction, and the wire outlet of the wire-passing groove k2 may be an opening at the other end of the wire-passing groove k2 in the extension direction.

[0148] When the wire-passing groove k2 is located on the side wall of the housing 10 in the second direction F2, it can be provided so as to extend in the first direction F1. When the wire-passing groove k2 is located on the side wall of the housing 10 in the first direction F1, it can be provided so as to extend in the second direction F2.

[0149] In this case, since the wire-passing groove k2 has an opening, the provision of the opening makes it easier to pass the wire harness through. Furthermore, since the concave wire-passing groove k2 is configured as the wire-passing portion 13a4, there is no need to add another structure to form a wire-passing space, and the structure of the housing 10 is simpler and less expensive.

[0150] Of course, in other embodiments, the wire-passing portion 13a4 may have a structure having a wire-passing hole additionally provided on the outer wall of the housing 10, such as a wire-passing rod having a wire-passing hole.

[0151] In some embodiments, referring to FIGS. 6 and 10, the side beam 13 is configured to form a wire-passing portion 13a4.

[0152] Specifically, when the wire-passing portion 13a4 is the wire-passing groove k2, the side beam 13 is composed of the upper arm beam 131 and the lower arm beam 132 in the above-described embodiment, and the space between the upper arm beam 131 and the lower arm beam 132 is the space where the wire-passing groove k2 is located. Alternatively, the wire-passing groove k2 is formed by recessing the side beam 13 away from the outer surface of the main body 11.

[0153] When the wire-passing portion 13a4 is a wire-passing hole, the side beam 13 can be made a hollow beam penetrating both ends of the extension direction thereof, so that the internal space of the side beam 13 forms the wire-passing 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-described embodiment, and the wire-passing hole is surrounded by the intermediate beam, the upper arm beam 131, and the lower wall beam.

[0154] In this case, the wire-passing section 13a4 is formed in the side beam 13, that is, the side beam 13 has space for passing wires, which can reduce the weight of the side beam 13 and enable wire passing, killing two birds with one stone.

[0155] In one specific embodiment, the upper arm beam 131 and the lower arm beam 132 are configured to form a wire-passing section 13a4 having a wire-passing space. In this case, the wire-passing space is formed by the space between the upper arm beam 131 and the lower arm beam 132, and the structure of the wire-passing section 13a4 is simple, killing two birds with one stone.

[0156] Fig. 11 is a schematic diagram showing the structure of a portion 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 in the structure shown in Fig. 12. Fig. 15 is a schematic diagram showing an application scenario of the structure shown in Fig. 11, and Fig. 16 is a side view of the structure shown in Fig. 14.

[0157] In some embodiments, referring to FIG. 11, the housing 10 also includes a seal 12 disposed on the top of the body 10 for providing a sealed connection with an external device.

[0158] Seal 12 is a component capable of preventing leakage of fluids or solid particles from between adjacent joining surfaces. Seal 12 is provided at the top of housing 10, dividing the top of housing 10 into an external region located on the outer periphery of seal 12 and an internal region surrounded by seal 12. Seal 12 seals and connects the two opposing surfaces of the top of housing 10 and an external device, forming a contact interface between these two surfaces, preventing fluids or solid particles from the external region on the outer periphery of seal 12 from entering the internal region surrounded by seal 12 through the contact interface between itself and the two surfaces, thereby exerting a sealing effect.

[0159] The seal 12 is either a seal ring or a seal pad. Specifically, the seal 12 may be made of a material such as rubber or silica gel. Specifically, the seal 12 may be an O-seal, a square seal, an irregular seal, or the like. The specific shape of the seal 12 can be adapted to the shapes of the top surface of the housing 10 and the two opposing surfaces of the external device. For example, if the top surface of the housing 10 and the two opposing surfaces of the external device are square, the seal 12 may be a square seal.

[0160] At this time, the housing 10 of the battery 100 and the external device 12 are hermetically connected via a seal, which ensures a reliable seal and is low cost.

[0161] As can be seen, the housing 10 of the battery 100 is sealed with the external device by the seal 12 and is fixedly connected to the external device by the attachment portion 13a3, with the top surface h of the housing 10 in contact with the external device.

[0162] 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 by the seal 12 on the sealing area hc. In this case, the internal region of the seal 12 is the internal region of the body 200, and the external region is the external region of the body 200. Fluids or solid particles outside the body 200 cannot leak into the internal region of the body 200. For example, stones or liquids scattered while the vehicle 1000 is running cannot collide with the internal region of the body 200, thereby realizing the sealing property and structural reliability of the internal region of the body 200.

[0163] 7 and 11, in some embodiments, the top of the housing 10 is configured with a mounting location 141b on the side away from the receiving cavity s. Here, the battery 100 is mounted to an external device via the top surface of the housing 10, and the mounting location 141b forms a partial structure of the external device.

[0164] Mounting position 141b is a mounting area formed in a partial area of ​​the top surface of housing 10 for mounting a fixed structure (hereinafter referred to as a mounting member), and this mounting member can be a part of the structure of an external device, and mounting position 141b can be a structure such as a mounting bracket or a mounting hole having a connecting function. Taking the example of vehicle body 200 of vehicle 1000 as the external device, mounting position 141b can be used to mount structures such as seat 300 of vehicle 1000 or an operating lever, and the structures such as seat 300 or an operating lever are fixedly connected to mounting position 141b on the top of box 10 via structures such as a mounting bracket or a mounting hole.

[0165] Specifically, the mounting material attached to mounting position 141b may be a local structure of the external device, and mounting position 141b for attaching the local structure of the external device is connected to the external device at the top of housing 10, and then forms a partial structure of the external device, and at this time, battery 100 is attached to the external device via the top of housing 10, and after mounting position 141b at the top of battery 100 is formed into the local structure of the external device, the mounting material and housing 10 of battery 100 are connected to realize connection with the external device.

[0166] In this way, by integrating and installing the partial structures of the battery 100 and the external device, the partial structure of the casing 10 of the battery 100 can be made a partial structure of the external device, thereby avoiding the battery 100 and the external device from being installed separately.

[0167] In other embodiments, the attachment material attached to attachment location 141b may be a structure other than an external device that is attached to attachment location 141b to simultaneously achieve a fixed connection between battery 100 and the external device.

[0168] In one 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 at the top of the housing 10 of the battery 100, the internal structure of the body 200 is formed at the mounting position 141b, and by integrating the battery 100 and the body 200, it is possible to avoid installing the battery 100 and the body 200 separately, simplify the structure of the vehicle 1000, and make it smaller and more compact.

[0169] As can be seen, the fixed connection of the housing 10, the body 200 and the seat 300 ensures that all structures are connected vertically to the top and bottom of the housing 10, reducing the installation space and installation load in other directions of the housing 10, reducing the load on the side structure and bottom structure of the housing 10 of the battery 100, and improving the structural stability of the vehicle 1000.

[0170] In some embodiments, referring to FIG. 7, the mounting location 141b includes a mounting hole configured in the top of the housing 10.

[0171] The mounting holes are through-holes that pass vertically through the mounting position 141b, and require the installation of fasteners when mounting the mounting sheet 300 or the like to the mounting position 141b, but the mounting holes may be smooth through-holes (for example, in the case of rivets), threaded through-holes (for example, in the case of screws), or other types of through-holes (hexagonal holes, square holes, waist holes, etc.). The specific shape of the fixing holes 11c3 is determined by the specific shape and specific setting method of the fasteners, and will not be described here.

[0172] The number of mounting holes is the same as the number of fasteners, and one fastener is installed in each mounting hole as a set. The corresponding mounting material is attached and positioned within the mounting hole by the fastener, thereby simultaneously fixing the mounting material to the casing 10 of the battery 100 and achieving a fixed connection between the mounting material and an external device.

[0173] In other embodiments, the mounting position 141b is not particularly limited and may include other structures such as metal fittings or elastic locks configured on the top of the housing 10.

[0174] 4 to 7 and 11, in some embodiments, the housing 10 includes a main body 11 that surrounds and defines the accommodating cavity s, and an attachment beam 141, the top of the main body 11 forming at least a portion of the top of the housing 10. The attachment beam 141 is provided on the top of the main body 11, and an attachment position 141b is configured on the side spaced apart from the main body 11.

[0175] The main body 11 may be an integrally molded structure or may be formed by combining a plurality of parts. The specific configuration of the main body 11 has been described in detail above, so a detailed description thereof will be omitted here.

[0176] One side of the top of the housing 10, which is spaced from the storage cavity s, has a top surface h, and the mounting position 141b and the top surface h are in communication with each other. The mounting beam 141 is provided on one side of the top of the main body 11 and has a structure with a certain load-bearing capacity in order to share the biasing force from the mounting material that is received by the top of the housing 10. As shown in Figures 15 and 16, when the mounting material is a seat 300, the pressure acts when the worker sits on the seat 300, and the pressure acts first on the mounting beam 141 and then on the top of the housing 10.

[0177] The mounting beam 141 may be provided directly on the surface of the top surface h, or may be provided on an uneven portion formed on the top surface h, and one or more load-bearing structures included in the mounting beam 141 are configured to form a mounting position 141b for fixing a mounting material on one side spaced from the top surface h, thereby realizing a connection between the mounting material and the top of the housing 10.

[0178] The installation form and extension direction of the load-bearing structure are set according to the size, weight, and specific structure of the mounting material that needs to be attached to the mounting position 141b, and the force acting on the top of the main body 11 is shared by the mounting beam 141, without being limited to a specific one, thereby improving the load-bearing capacity of the casing 10 of the battery 100.

[0179] In some embodiments, the mounting beam 141 is fixedly connected to or integrally formed with the body 11 .

[0180] The mounting beam 141 and the main body 11 can be fixedly joined by fastening with a fastener, fastening with an engagement structure, welding, adhesive, heat fusion bonding, etc. Of course, the mounting beam 141 and the main body 11 may be integrally molded by injection molding, die casting, forging, cold pressing, hot pressing, etc.

[0181] If the main body 11 is made of metal (e.g., aluminum, iron, stainless steel, etc.), the mounting beam 141 and the main body 11 can be integrally molded by die casting, forging, hot pressing, cold pressing, etc. If the main body 11 is made of plastic (e.g., PP, PE, ABS, etc.), the mounting beam 141 and the main body 11 can be integrally molded by injection molding. The mounting beam 141 and the main body 11 can also be connected after being molded separately. If the mounting beam 141 and the main body 11 are made of metal, the mounting beam 141 and the main body 11 can be welded or bonded together. If the mounting beam 141 and the main body 11 are made of plastic, the mounting beam 141 and the main body 11 can be bonded together.

[0182] If the mounting beam 141 and the main body 11 are fixedly connected, the molding process of the mounting beam 141 and the main body 11 becomes easier, and the manufacturing cost of the housing 10 can be reduced.

[0183] If the mounting beam 141 is integrally formed with the main body 11, the assembly of the housing 10, the external device, and the mounting material becomes easy.

[0184] In other embodiments, the main body 11 may be connected to a part other than the mounting beam 141, and the connection method may be integral molding or fixed connection.

[0185] In some embodiments, referring to Figures 7 and 11, the mounting beam 141 includes at least one protrusion 141a, each of which is provided to protrude 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.

[0186] The protrusions 141a are load-bearing structures included in the mounting beam 141 described above, and are provided so as to protrude in a direction away from the accommodating cavity s, facing the plane on which the top surface h of the housing 10 is located, and the protrusions 141a themselves have a certain height and are provided so as to protrude relative to the top surface h of the housing 10. In the mounting position 141b, all of the protrusions 141a are formed on one side away from the main body 11, and in this case, when a mounting material is attached to the mounting position 141b, the protrusions 141a do not come into direct contact with the top surface h but come into direct contact with the structure of the protrusions 141a, so that the force applied to the top surface of the housing 10 is distributed by the protrusions 141a, and the load-bearing capacity of the top of the housing 10 is increased.

[0187] Each of the protrusions 141a can have a structure that is open on multiple sides centered on one end, and the top surface h1 of the main body 11 is covered by the open opening of each of the protrusions 141a, thereby forming a weight reduction passage 141a1. The weight reduction passage 141a1 can be formed by making the inside of the protrusion 141a hollow or by digging holes or grooves, thereby reducing the weight of the housing 10.

[0188] In one specific embodiment, a weight-reducing passage 141a1 is provided inside each protrusion 141a, penetrating in the extension direction thereof, and the provision of this weight-reducing passage 141a1 reduces the weight of each protrusion 141a, thereby reducing the weight of the entire housing 10 and reducing costs. Each of the penetrating weight-reducing passages 141a1 can form a hidden passage, and in another embodiment, the hidden passage can be used to perform operations such as dark line placement.

[0189] 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.

[0190] The direction referred to by "same direction" may specifically be the first direction F1 or the second direction F2 described above, or may be a direction that is coplanar with and intersects the first direction F1 and the second direction F2, and is not specifically limited.

[0191] The fact that all of the protrusions 141a are spaced apart means that there is a set interval between each pair of adjacent protrusions 141a in a direction intersecting the extension direction of the protrusions 141a. This set interval creates a buffer space between each pair of adjacent protrusions 141a, preventing external forces acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the protrusions 141a spaced apart from one another can provide a sufficient support area and fixing positions, enabling the mounting material to be supported over a large area and suitable for mounting materials of different volumes and sizes.

[0192] Since all the protrusions 141a are arranged parallel to one another in the same direction, the buffering space extends in the same direction as the protrusions 141a, and in practical applications, buffering can be achieved at any position in the extension direction of the mounting beam 141.

[0193] The set distance between each two adjacent protrusions 141a may be equal or unequal, and as can be understood, the set distance between each two adjacent protrusions 141a is equal to ensure uniform support of the mounting material.

[0194] In some embodiments, all of the protrusions 141a are flush with one side facing away from the body 11.

[0195] By installing all of the protrusions 141a so that they protrude in the same direction and making the protruding height of all of the protrusions 141a the same, one side of all of the protrusions 141a that is away from the mounting cavity forms a flat plane in a certain direction so that it forms a flat plane on a horizontal plane, and the mounting material can be placed on the flat plane and mounted, making the mounting more smooth and easy, and also achieving a strong bond between the mounting material and the mounting beam 141.

[0196] In one specific embodiment, the protrusion 141a can be a rectangular pillar-shaped structure, and all the same sides of the protrusion 141a are on the same plane, which together define and form the mounting position 141b for mounting the mounting material, thereby allowing the mounting material to be smoothly placed on the mounting beam 141.

[0197] In some embodiments, referring to Figures 4, 7 and 11, the housing 10 further includes side reinforcing beams 14 installed on the top of the main body 11 and extending from the center of the top of the main body 11 toward the outer edges of the top of the main body 11 on opposite sides.

[0198] The side reinforcement beams 14 are beam structures installed on top of the main body 11 to reinforce the strength of the main body 11. As can be understood, the side reinforcement beams 14 are located outside the main body 11. Specifically, the main body 11 may be integrally connected to the side reinforcement beams 14 to form an integrated unit, or may be assembled and connected to form an integrated unit. Integral connections include, but are not limited to, welding, integral molding, fusion, etc. Assembled connections include, but are not limited to, interlocking, screw connections, etc.

[0199] The side impact reinforcement beams 14 may extend from the center of the top of the main body 11 toward the outer edges on both opposing sides of the top of the main body 11 in the first direction F1, in which case the side impact reinforcement beams 14 can reinforce the side impact prevention ability 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 toward the outer edges on both opposing sides of the top of the main body 11 in the second direction F2, in which case the side impact reinforcement beams 14 can reinforce the side impact prevention ability of the housing 10 in the second direction F2.

[0200] The lateral reinforcement beams 14 may extend in two directions on the same line 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, or may extend in two intersecting directions from the middle of the top of the main body 11 toward the outer edges on opposite sides of the top of the main body 11. When the lateral reinforcement beams 14 extend in two directions on the same line from the middle of the top of the main body 11 toward the outer edges on opposite sides, the lateral reinforcement beams 14 can be realized by a single straight beam, making the structure simpler.

[0201] The side impact reinforcement beams 14 may extend to the outer edges on both sides, may extend to the region between the outer edges on both sides and the middle, or may extend to the region beyond the outer edges on both sides; in other words, as long as they extend from the middle of the top of the main body 11 toward the outer edges on opposing sides of the top of the main body 11, the extension length of the side impact reinforcement beams 14 is not specifically limited.

[0202] When the battery 100 is applied to a vehicle 1000 and the top of the housing 10 is configured as the chassis of the vehicle 1000, the vehicle 1000 has poor side impact prevention capabilities in the left and right directions, so the side impact reinforcement beam 14 can be designed to extend from the center of the top of the main body 11 toward the outer edges on both sides of the top of the main body 11 in the left and right directions of the vehicle 1000, thereby strengthening the vehicle 1000's side impact prevention capabilities in the left and right directions and improving the safety of the vehicle 1000.

[0203] In this case, by providing a side impact reinforcement beam 14 at 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 of the battery 100 and the vehicle 1000.

[0204] When main body 11 includes frame 11b and carrier 11a, side impact reinforcing beam 14 is provided at least on the top of carrier 11a. In this case, since the top of carrier 11a forms at least a part of the top of main body 11, there is sufficient space in carrier 11a for attaching side impact reinforcing beam 14.

[0205] In some embodiments, the side impact reinforcement beams 14 extend to connect to the top of the frame 11b.

[0206] 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 extend to connect with the top of frame 11b. In addition to directly connecting frame 11b and carrier 11a, side impact reinforcement beam 14 can strengthen the connection, thereby improving the reliability of the connection between frame 11b and carrier 11a.

[0207] In some embodiments, the number of side reinforcement beams 14 is at least one, and all of the side reinforcement beams 14 extend in the same direction and are spaced apart from one another.

[0208] The direction referred to by "same direction" may specifically be the first direction F1 or the second direction F2 described above, or may be a direction that is coplanar with and intersects the first direction F1 and the second direction F2, and is not specifically limited.

[0209] All of the side impact reinforcing beams 14 extend in the same direction, and each side impact reinforcing beam 14 can reinforce the side impact prevention capability of the casing 10 in the extension direction, thereby strengthening the side impact prevention capability of the casing 10 in that extension direction. As can be understood, each side impact reinforcing beam 14 is arranged at intervals in a direction intersecting this "same direction," and by arranging them in this manner, the strength of the casing 10 can be reinforced at multiple positions so that the structural strength and side impact prevention capability of the casing 10 become more uniform.

[0210] In some embodiments, at least one of the side impact reinforcement beams 14 is configured as an attachment beam 141 having an attachment location 141 b configured on one side spaced apart from the body 11 .

[0211] For details of the mounting beam 141 and the mounting position 141b, please refer to the above explanation and a detailed description will be omitted here. When there is one side impact reinforcement beam 14, this side impact reinforcement beam 14 is called the mounting beam 141. When there are at least two side impact reinforcement beams 14, some of them can be called mounting beams 141. Specifically, when there are at least two side impact reinforcement beams 14, the side impact reinforcement beam 14 closer to the front of the vehicle 1000 can be used as the mounting beam 141 for mounting the seat 300 (the seat 300 may be the seat 300 in the driver's cab).

[0212] In this case, by using at least one of the side impact reinforcement beams 14 as the mounting beam 141, not only is it possible to provide a side impact prevention effect, but it is also possible to mount other mounting members, and it can be used for both purposes.

[0213] In some embodiments, the side projection reinforcement beam 14 includes at least one protrusion 141a, and each protrusion 141a is provided protruding from the top of the main body 11 in a direction away from the accommodating cavity s, and each protrusion 141a forms a weight reduction passage 141a1 together with the main body 11.

[0214] The convex portion 141a of the side collision reinforcing beam 14 has the same configuration as the convex portion 141a in the case where the structure of the mounting beam 141 was explained in the above embodiment, and for specific details, please refer to the above explanation. The convex portion 141a is provided so as to face the plane on which the top surface h1 of the main body 11 is located and to protrude in a direction away from the accommodation cavity s, and the convex portion 141a itself has a certain height and is provided so as to protrude relative to the top surface h1 of the main body 11.

[0215] Each of the protrusions 141a can have a structure that is open on multiple sides centered on one end, and the top surface h1 of the main body 11 is covered by the open opening of each of the protrusions 141a, thereby forming a weight reduction passage 141a1. The weight reduction passage 141a1 can be formed by making the inside of the protrusion 141a hollow or by digging holes or grooves, thereby reducing the weight of the housing 10.

[0216] In one specific embodiment, a weight-reducing passage 141a1 is provided inside each protrusion 141a, penetrating in the extension direction thereof, and the provision of this weight-reducing passage 141a1 reduces the weight of each protrusion 141a, thereby reducing the weight of the entire housing 10 and reducing costs. Each of the penetrating weight-reducing passages 141a1 can form a hidden passage, and in another embodiment, the hidden passage can be used to perform operations such as dark line placement.

[0217] In some embodiments, referring to FIG. 7, all of the protrusions 141a extend in the same direction and are spaced apart from one another.

[0218] The fact that all of the protrusions 141a are spaced apart means that there is a set interval between each pair of adjacent protrusions 141a in a direction intersecting the extension direction of the protrusions 141a. This set interval creates a buffer space between each pair of adjacent protrusions 141a, preventing external forces acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the protrusions 141a spaced apart from one another can provide a sufficient support area and fixing positions, enabling the mounting material to be supported over a large area and suitable for mounting materials of different volumes and sizes.

[0219] Since all of the protrusions 141a are arranged parallel to one another in the same direction, the buffering space extends in the same direction as the protrusions 141a, and in practical applications, buffering can be achieved at any position in the extension direction of the side reinforcement beam 14.

[0220] The set 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 the mounting beam 141, the set distance between each two adjacent protrusions 141a is equal to ensure uniform support of the mounting material.

[0221] In some embodiments, all of the protrusions 141a are flush with one side facing away from the body 11.

[0222] One side of all the protrusions 141a is located on the top surface h1 of the main body 11, and all the protrusions 141a are installed convexly facing the same direction, and the height of the convexity is set to be the same.By doing so, all the protrusions 141a form a flat surface on a horizontal plane, forming a flat plane on one side away from the mounting cavity, thereby realizing a strong connection between the mounting material and the mounting beam 141.

[0223] In one specific embodiment, the protrusion 141a can be a rectangular pillar-shaped structure, and all the same sides of the protrusion 141a are on the same plane, which together define and form the mounting position 141b for mounting the mounting material, thereby allowing the mounting material to be smoothly placed on the mounting beam 141.

[0224] In some embodiments, referring to FIG. 10, the housing 10 is formed with a battery cavity s1 for accommodating the battery unit 20 and a high-pressure cavity s2 for accommodating the high-pressure case, which are provided independently of each other.

[0225] The high-voltage case is an important safety barrier for the 100 battery pack. It is equipped with a high-voltage control system and is mainly used to turn on or off the high-voltage circuit according to the overall vehicle electronic control requirements, provide current and leakage detection terminals, realize controllable tape carrier cutoff when the external current of the 100 battery pack is excessive, realize high-voltage circuit cutoff when the external line of the 100 battery pack is short-circuited, prevent the 100 battery pack from catching fire, and easily cut off the high-voltage circuit when the 100 battery pack is being repaired.

[0226] The battery cavity s1 and the high-pressure cavity s2 being provided independently of each other means that the battery cavity s1 and the high-pressure cavity s2 are sealed from each other. To provide the battery cavity s1 and the high-pressure cavity s2 independently, the battery cavity s1 and the high-pressure cavity s2 can be formed as two separate independent components. For example, a first and a second independent component can be provided 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 can be provided inside the housing 10 to separate the storage cavities s formed inside the housing 10 into the independent battery cavities s1 and the high-pressure cavities s2. Alternatively, all storage cavities s formed inside the housing 10 can be battery cavities s1, and a high-pressure chamber 15 can be configured outside the housing 10 to form the high-pressure cavity s2, thereby separating the battery cavities s1 and the high-pressure cavities s2.

[0227] The battery cavity s1 is for accommodating the battery unit 20, and the high-pressure cavity s2 is for accommodating the high-pressure case. When the battery cavity s1 is provided independently of the high-pressure cavity s2, high-temperature gas leaking due to thermal failure of the battery unit 20 in the battery cavity s1 will not enter the high-pressure case, and will not cause thermal damage to the high-pressure control system in the high-pressure case. This ensures the normal control function of the high-pressure control system and improves the safety performance of the battery 100.

[0228] 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 located outside the main body 11 and surrounds and forms a high-pressure cavity s2 by itself or together with the main body 11.

[0229] The high-pressure chamber 15 can be structured as a housing 22, the interior of which is hollow to form the high-pressure chamber 15 and to place the high-pressure case. By providing the high-pressure chamber 15 outside the main body 11 and forming a battery cavity s1 with the main body 11 (in this case, the battery cavity s1 corresponds to the storage cavity s), the high-pressure cavity s2 and the battery cavity s1 can be provided independently.

[0230] When the high pressure chamber 15 forms the high pressure cavity s2 together with the main body 11, 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 forms the high pressure cavity s2 by surrounding it, only an attachment relationship exists between the high pressure chamber 15 and the main body 11.

[0231] 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 storage cavity s formed by the main body 11 can be used as a battery storage cavity s1 to store a single battery 20, thereby improving the electrical capacity of the battery 100.

[0232] In some embodiments, referring to FIGS. 11 and 12, the high pressure chamber 15 is disposed on the top of the main body 11 so as to protrude.

[0233] The high-pressure chamber 15 protrudes from the top of the main body 11, and is located outside the main body 11 and installed on the top surface h1 of the main body 11. When the housing 10 of the battery 100 is used as the chassis of the vehicle 1000, the high-pressure chamber 15 is located at the top of the main body 11, and is not exposed to the outside of the vehicle 1000, and is protected from external impacts (such as stones flying while the vehicle 1000 is running), making the high-pressure chamber 15 safer.

[0234] As can be understood, when the main body 11 includes the frame 11b and the carrier 11a, the carrier 11a constitutes at least a part of the top of the main body 11, and the high pressure chamber 15 is installed on the top of the carrier 11a and surrounds itself or together with the carrier 11a to form the high pressure cavity s2. In this case, since the carrier 11a constitutes most of the top of the main body 11, installing the high pressure chamber 15 on the top of the carrier 11a increases the installation space for the high pressure chamber 15 and makes the installation more stable.

[0235] 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 provided at the top of the frame 11b, and may be specifically set depending on the mounting method between the frame 11b and the carrier 11a.

[0236] In some embodiments, referring to FIGS. 11-13, the high pressure chamber 15 is located adjacent the top outer edge of the body 11.

[0237] Regarding the outer edge of the top of the body 11, this includes the top of the body 11 being installed on the outer edge of one side of the vehicle 1000 in the forward direction, the top of the body 11 being installed on the outer edge of one side of the vehicle 1000 in the rearward direction, the top of the body 11 being installed on the outer edge of one side of the vehicle 1000 in the leftward direction, and the top of the body 11 being installed on the outer edge of one side of the vehicle 1000 in the rightward direction.

[0238] In one practical example, the high pressure chamber 15 has its top close to the main body 11 installed on the outer edge of one side in the rear direction of the vehicle 1000, that is, the high pressure chamber 15 is located close to the rear of the vehicle 1000.In this case, the high pressure chamber 15 can be located corresponding to the passenger space behind the driving space of the vehicle 1000, and in particular, can be located corresponding to below the seat 300 in the passenger space, so as not to occupy the activity space of the vehicle 1000.

[0239] In some embodiments, referring to Figures 4, 6, and 11 to 13, the high-pressure chamber 15 is arranged sequentially with the side reinforcement beam 14 in a first direction F1, and the side reinforcement beam 14 extends in a second direction F2 intersecting the first direction F1.

[0240] In the case where the housing 10 includes the side reinforcing beams 14 , both the high-pressure chamber 15 and the side reinforcing beams 14 may be provided on the top of the main body 11 .

[0241] The fact that the high-pressure chamber 15 and the side reinforcement beams 14 are arranged sequentially in the first direction F1 means that the high-pressure chamber 15 is located on one side of all of the side reinforcement beams 14 in the first direction F1. The side reinforcement beams 14 also extend in the second direction F2 intersecting with the first direction F1 without interfering with the high-pressure chamber 15, making the structural arrangement of the high-pressure chamber 15 and the side reinforcement beams 14 rational and resulting in a high utilization rate of the space at the top of the main body 11.

[0242] In a specific embodiment, referring to Figure 4, the high-pressure chamber 15 includes a chamber cover 15a and a chamber case 15b provided at the top of the main body 11 and having an open high-pressure cavity s2 spaced apart from the main body 11, and the chamber cover 15a detachably covers one open side of the high-pressure cavity s2.

[0243] The chamber case 15b and the main body 11 may be connected by welding, fusion, adhesion, fastening, etc. Without being limited thereto, the chamber case 15b may be made of plastic. The chamber cover 15a and the chamber case 15b may be detachably connected by a fastener or by engagement, and the specific form is not limited thereto.

[0244] At this time, a high-pressure cavity s2 is formed by the chamber case 15b, and the high-pressure cavity s2 is sealed by the chamber lid 15a. Since the chamber lid 15a and the chamber case 15b are detachably connected, installation and repair of the high-pressure case are easy.

[0245] Fig. 17 is a schematic diagram showing the structure of a portion 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 plan view of the structure shown in Fig. 17.

[0246] In some embodiments, referring to Figures 17 to 21, the housing 10 further includes a middle passage beam 16 extending from the top of the main body 11 along a first direction F1 and positioned equidistant from the outer edges on both sides of the top of the main body 11 in a second direction F2 intersecting the first direction F1, and having a wire passage 16a for passing a wire harness.

[0247] In a conventional vehicle 1000, a middle aisle beam 16 is generally provided on the chassis of the body 200 of the vehicle 1000. The middle aisle 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 for ensuring the collision transmission path of the body 200 and the rigidity of the bottom plate of the body 200. The middle aisle 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.

[0248] In this embodiment, the middle aisle beam 16 of the vehicle 1000 is directly integrated into the top of the main body 11 of the housing 10. Specifically, the middle aisle beam 16 extends in the first direction F1 (corresponding to the front-rear direction of the vehicle body 200) and is disposed equidistant from both outer edges of the top of the vehicle body 11 in the second direction F2 (corresponding to the left-right direction of the vehicle body 200), and is disposed in a central region of the top of the vehicle body 11.

[0249] Generally, the middle passage beam 16 has a hollow structure in order to reduce the weight of the vehicle body 200. In this embodiment, by utilizing the hollow structure provided inside the middle passage beam 16 to form a wire passage 16a for passing the wire harness, it is possible to reduce the weight and also to realize the arrangement of the wire harness, allowing the arrangement of the wire harness to be performed more flexibly and safely.

[0250] 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, or fastening multiple sheet metal plates together, as long as it can form the wire passage 16a. The wire passage 16a may be located inside the intermediate passage beam 16 (e.g., a hole passage inside the intermediate passage beam 16) or outside the intermediate passage beam 16 (e.g., a recessed groove passage outside the intermediate passage beam 16). The intermediate passage beam 16 may form the wire passage 16a together with the main body 11, or may itself surround the wire passage 16a. The intermediate passage beam 16 and the main body 11 can be connected to each other as an integral unit by welding, fusion, fastening, or the like.

[0251] The wire passage 16a provided in the intermediate passage beam 16 may extend along the extending direction of the intermediate passage beam 16 (i.e., the first direction F1), and may be designed according to other needs without being specifically limited as long as wires can be passed through. The intermediate passage beam 16 may be provided with a plurality of independent wire passages 16a, allowing different types of wire harnesses to be passed through separately, facilitating installation and maintenance.

[0252] In this case, if the top of the housing 10 is configured as the chassis (the chassis that is the floor of the vehicle body 200) of the vehicle 1000, there is no need to additionally provide the middle passage beam 16, improving the workability of assembling the vehicle body 200. On the other hand, by utilizing the hollow structure formed inside the middle passage beam 16 to form a wire passage 16a for passing the wire harness, it is possible to reduce weight and also to realize the arrangement of the wire harness, allowing for more flexible wiring of the wire harness.

[0253] In some embodiments, referring to FIG. 20, the middle passage beam 16 is provided at the top of the main body 11 and includes a beam seat 161 having a wire passage groove 16a1 formed therein as a wire passage 16a, and the wire passage groove 16a1 is recessed toward the storage cavity s.

[0254] The beam seat 161 is provided directly on the main body 11, and is fixed to the main body 11 by welding, fusion, fastening, or other methods. The beam seat 161 is formed with a wire passage groove 16a1 recessed toward the accommodating cavity s, i.e., the wire passage groove 16a1 has a notch spaced apart from the accommodating cavity s, and this notch makes it easy to insert the wire harness.

[0255] The wire passing groove 16a1 may be recessed into the surface of one side of the beam seat 161 away from the accommodating cavity s to form a continuous groove structure, or may be a plurality of wire passing sections having grooves recessed toward the accommodating cavity s formed on the surface of one side of the beam seat 161 away from the accommodating cavity s, with each wire passing section being arranged at intervals in a set direction, and all of the recessed grooves of the wire passing sections together forming the wire passing groove 16a1 of the beam seat 161.

[0256] At this time, the beam seat 161 forms a wire passage groove 16a1 recessed toward the receiving cavity s, which makes it easy to attach the wire harness.

[0257] In some embodiments, referring to FIG. 20, the number of the wire passing grooves 16a1 is plural, and all the wire passing grooves 16a1 extend in the same direction and are spaced apart from each other.

[0258] A plurality of wire passing grooves 16a1 are provided, and the plurality of wire passing grooves 16a1 can extend in the same direction (for example, the first direction F1) at intervals. Each wire passing groove 16a1 can accommodate one type of wire harness (the types of wire harnesses can be classified according to the connection target of the wire harness, such as a wire harness connected to an air conditioner, a wire harness connected to a vehicle light, a wire harness connected to a power drive system, etc.).

[0259] This allows different types of wire harnesses to be arranged independently, making it easier to install and maintain the wire harnesses.

[0260] In some embodiments, the wire passage groove 16a1 is configured to engage with a wire harness passing through it.

[0261] To secure the wire harness in the wire passing groove 16a1, specifically, the cutout dimensions of the wire passing groove 16a1 may be made equal to the diameter of the wire harness to be inserted therethrough, or the two may be tightly fitted together. Specifically, a fastening member may be provided in the cutout of the wire passing groove 16a1, one end of the fastening member may be rotatably connected to one side of the cutout of the wire passing groove 16a1, and the other end may be detachably attached to the other side of the cutout of the wire passing groove 16a1. After the wire harness is placed in the wire passing groove 16a1, the fastening member may be engaged with the cutout of the wire passing groove 16a1, thereby securing the wire harness in the wire passing groove 16a1.

[0262] This makes it possible to avoid noise caused by the wobbling of the wire harness, and also to avoid the problem of the wire harness coming off the wire passage groove 16a1 and being damaged.

[0263] In some embodiments, referring to FIG. 20, the middle passage beam 16 further includes a beam cover 162 that is detachably covered on the opening side of the wire passage groove 16a1.

[0264] The opening side of the wire passing groove 16a1 is the side where the notch of the wire passing groove 16a1 is present. The beam cover 162 is detachably covered on the opening side of the wire passing groove 16a1, i.e., detachably connected to the beam seat 161. Specifically, the beam cover 162 is detachably engaged with the beam seat 161, or the beam cover 162 and the beam seat 161 are detachably connected by a fastener (e.g., a bolt). A method for detachably connecting the beam cover 162 and the beam seat 161 can adopt a common setting in the art, and there is no need to limit the description here.

[0265] At this time, by covering the notch of the wire passage groove 16a1 with the beam cover 162, it is possible to prevent external ash and moisture from entering the wire passage groove 16a1 and corroding the wire harness, and also to protect the wire harness from being crushed by external forces, thereby improving the safety of the battery 100.

[0266] In some embodiments, the high pressure cavity s2 communicates with the wire passage 16a.

[0267] As can be appreciated, typically, a wire harness is pulled out from the high-voltage case in the high-voltage cavity s2 to supply power to power consuming equipment, and so the wire harness passes through the high-voltage cavity s2 and the wire passage 16a.

[0268] The communication between the high-pressure cavity s2 and the wire passage 16a means that the wire harness passed through the high-pressure cavity s2 can enter the wire passage 16a. Specifically, the high-pressure cavity s2 has a wire passage opening facing the entrance of the wire passage 16a. In this case, there is no obstacle between the wire passage opening and the entrance of the wire passage 16a, and the wire harness passed through the wire passage opening can enter the entrance of the wire passage 16a straight without bending. Specifically, the high-pressure cavity s2 may have a wire passage opening that does not face the entrance of the wire passage 16a but is spatially connected thereto. In this case, there is an obstacle between the wire passage opening and the entrance of the wire passage 16a (the obstacle may be formed by the central passage beam 16 or another structure), and the wire harness that exits through the wire passage opening can enter the wire passage 16a through the entrance of the wire passage 16a after bypassing the obstacle.

[0269] At this time, since the high-pressure cavity s2 and the wire passage 16a are in communication with each other, it is possible to realize the arrangement of the wire harness coming out of the high-pressure cavity s2 via the wire passage 16a.

[0270] In some embodiments, referring to FIGS. 17 and 21, the middle passage beam 16 and the high pressure chamber 15 are disposed adjacent to each other along the first direction F1.

[0271] The middle aisle beam 16 generally corresponds to extending 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 middle aisle beam 16 in the first direction F1, and the high pressure chamber 15 can be disposed in front of or behind the middle aisle beam 16. Specifically, the high pressure chamber 15 can be disposed behind the middle aisle beam 16 corresponding to the position of the rear chassis of the vehicle body 200, and the position of the rear chassis of the vehicle body 200 can be used to mount the seat 300 in the passenger compartment of the vehicle 1000, so the positioning of the high pressure chamber 15 allows the high pressure chamber 15 to be hidden in the space below the seat 300, thereby improving the space utilization rate of the passenger compartment of the vehicle 1000.

[0272] In some embodiments, referring to FIG. 11, a first region ha and a second region hb surrounding the first region ha are formed on the top surface h of the housing 10, and a plurality of mounting portions 13a3 are formed in the second region hb, and the battery 100 is attached to an external device via the mounting portions 13a3.

[0273] The first region ha and the second region hb can be formed by another structural division, such as placing a seal 12 on the top of the housing 10 and dividing the top surface h of the housing 10 into a second region hb located around the seal 12 via the seal 12, and a first region ha located on the inner periphery of the seal 12, and when the battery 100 is attached to an external device via the mounting portion 13a3, the first region ha and the second region hb are independent of each other.

[0274] The first region ha and the second region hb can also be automatically partitioned on the top surface h so that there is no other structural gap between the first region ha and the second region hb, and the first region ha and the second region hb are connected to each other when the battery 100 is attached to an external device via the mounting portion 13a3.

[0275] 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 configurations are not limited.

[0276] In one specific embodiment, for example, when the external device is the body 200 of the vehicle 1000, the mounting 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. In this case, the housing 10 only receives the vertical force of the body 200, reducing the force transmission path and being advantageous for improving the rigidity and lateral pressure resistance of the entire vehicle.

[0277] As can be understood, the top surface h of the housing 10 may include, in addition to the first region ha and the second region hb, other regions that may be located between, around, or within the first region ha and the second region hb, and is not particularly limited in this application.

[0278] In some embodiments, with reference to FIGS. 13 and 14, the distance L2 between the geometric centers of the orthogonal projections of each two adjacent mounting portions 13a3 in the second region hb is 80 mm to 500 mm.

[0279] Orthogonal projection is a projection in which a parallel projection line is projected perpendicularly to the projection surface, i.e., a projection in which the mounting portion 13a3 is projected onto the second region hb in a direction perpendicular to the second region hb. When connecting the mounting portions 13a3 to an external device, each mounting portion 13a3 has a mounting force receiving point whose geometric center, orthogonally projected onto the second region hb, is the mounting force receiving point. By limiting the distance between two adjacent mounting force receiving points (i.e., distance L2) to 80 to 500 mm, the battery 100 can be mounted uniformly to the external device, and the connection strength between the battery 100 and the external device can be improved.

[0280] In one specific embodiment, when the external device is the body 200 of the vehicle 1000, the mounting portion 13a3 is installed to include a plurality of mounting holes k1, and the housing 10 of the battery 100 is connected to the body 200 through the plurality of mounting holes k1. The distance L2 between the geometric centers of adjacent mounting holes k1 is within a specified range to ensure that the set distance between the mounting holes k1 (i.e., the distance L2) is controllable. Controlling the set distance between the mounting holes k1 ensures a substantially uniform distribution among the plurality of mounting positions on the housing 10, uniformly distributing the force received by the body 200, and further improving the connection rigidity between the body 200 and the housing 10 at each position.

[0281] As can be understood, in some other embodiments, for example, when individual configuration is required such that the mounting portion 13a3 is divided into a dense mounting area and a sparse mounting area, the distance between each mounting hole k1 in the dense mounting area (i.e., the distance L2) is set as close as possible to the 80 mm side, and the distance between each mounting hole k1 in the sparse mounting area (i.e., the distance L2) is set as close as possible to the 500 mm side, thereby meeting the individualized needs of local dense mounting and local sparse mounting.

[0282] In some embodiments, referring to FIGS. 13 and 14, the distance L2 between the geometric centers of the orthogonal projections of each two adjacent mounting portions 13a3 in the second region hb is 80 mm to 300 mm.

[0283] The distance L2 is within a range of 80 mm to 300 mm, which means that the connection strength between the battery 100 and the external device can be ensured while ensuring a uniform connection between the battery 100 and the external device.

[0284] In some embodiments, referring to Figures 13 to 14, the top surface h of the housing 10 also has a seal area hc formed between the first region ha and the second region hb, surrounding the first region ha, for attaching a seal 12 for contacting an external device.

[0285] The seal 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. Its main role is to attach the seal 12 to prevent the area of ​​the seal area hc from becoming excessively large and to isolate the first area ha and the second area hb from each other, and it is set to match the size, volume, and shape of the seal 12 as much as possible to ensure that the entire seal 12 is assembled into the seal area hc.

[0286] As can be seen, the seal 12 has different states within the sealing area hc, and when the seal 12 contacts an external device and the housing 10 is fixedly connected to the external device, the seal 12 is in a compressed state and undergoes a certain deformation to ensure sealing, and when the battery 100 is separated from the external device, the seal 12 returns to its original state.

[0287] In one specific embodiment, taking the external device as the body 200 of a vehicle 1000 as an example, the battery 100 may be attached to the bottom of the body 200 and sealed to the body 200 by a seal 12 on the sealing area hc. In this 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, so that 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 collide with the interior of the body 200, thereby realizing the sealing and structural reliability of the interior of the body 200.

[0288] As can be understood, when the housing 10 includes the seal 12, the seal 12 is attached to the seal area hc and seals and separates the first region ha and the second region hb. The specific arrangement of the seal 12 has been described in detail above and will not be repeated here. However, in addition to the first region ha, the seal area hc, and the second region hb, the top surface h of the housing 10 can include other regions that may be located either inside the first region ha or outside the second region hb, and is not particularly limited in this application.

[0289] In some embodiments, referring to FIGS. 13 and 14, the shortest distance L1 between the geometric center of the orthogonal projection of the mounting portion 13a3 in the second region hb and the outer edge of the seal area hc is 30 mm to 200 mm.

[0290] The mounting portions 13a3 are projected onto the second region hb in a direction perpendicular to the second region hb, and when the mounting portions 13a3 are connected to an external device, each mounting portion 13a3 has a mounting force receiving point, and the geometric center of each mounting portion 13a3 projected onto the second region hb is the mounting force receiving point of each mounting portion 13a3. The shortest distance L1 between the geometric center of the orthogonal projection of each mounting portion 13a3 on the second region hb and the outer edge of the sealing area hc is the shortest distance between the mounting force receiving point of each mounting portion 13a3 and the outer edge of the sealing area hc.

[0291] The outer edge of the seal area hc is a boundary line shared between the seal area hc and the second region hb, and naturally, the seal area hc also has an inner edge that is a boundary line shared between the seal area hc and the first region ha. When assembling the seal 12, the side edges of the seal 12 are aligned with the inner and outer side edges of the seal area hc so that the seal 12 completely covers the seal area hc.

[0292] The shortest distance L1 between the geometric center of the orthogonal projection of the mounting portion 13a3 in the second region hb and the outer edge of the seal area hc is the length of a perpendicular line drawn from the geometric center of each mounting portion 13a3 to the outer edge of the seal area hc to ensure that the distance between the seal 12 and the mounting portion 13a3 is within a specified range.

[0293] In one specific embodiment, for example, when the body 200 of the vehicle 1000 is used as the external device, the shortest distance (i.e., distance L1) between the mounting force receiving point of the mounting portion 13a3 and the outer edge of the sealing area hc is controlled to 30 mm to 200 mm, thereby preventing the mounting force receiving point of the mounting portion 13a3 from being too far from the seal 12, on the one hand, ensuring the sealing effect of the seal 12 inside the body 200, and on the other hand, reducing the mounting moment when each mounting portion 13a3 is mounted to the body 200, effectively shortening the mounting mount arm, and ensuring the connection rigidity between the battery 100 and the body 200.

[0294] In some embodiments, referring to FIGS. 13 and 14, the shortest distance L1 between the geometric center of the orthogonal projection of the mounting portion 13a3 in the second region hb and the outer edge of the seal area hc is 50 mm to 100 mm.

[0295] In the range of 50 mm to 100 mm, the attachment force receiving point of the attachment portion 13a3 can be prevented from being too far away from the seal 12, and the connection strength between the battery 100 and the external device can be ensured while ensuring the sealing isolation effect of the seal 12 between the first area ha and the second area hb.

[0296] In some embodiments, the seal area hc is coplanar with the second region hb.

[0297] A coplanar surface is also called a coplanar surface, and a coplanar surface means that the seal area hc and the second area hb share the same plane in three-dimensional space, and in this case, both the seal area hc and the second area hb are configured as flat planes, and no angle is formed between them.

[0298] In one 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 seal area hc for installing the seal 12 that performs the sealing function and the second area hb in which the mounting material is configured to perform the mounting function have the same height in the vertical direction, and in this case, the mounting force receiving point of each mounting portion 13a3 is on the same plane and at the same height as the seal area hc, and both the mounting force receiving point and the seal 12 only receive vertical force, thereby reducing the lateral structural force of the housing 10 and the body 200 and improving the rigidity of the vehicle 1000.

[0299] In some embodiments, referring to FIG. 11, the first region ha, the second region hb, and the seal area hc are coplanar.

[0300] At this time, the same plane on which the first area ha, the second area hb, and the seal area hc are located comes into contact with the external device, so the contact area between the top surface h of the housing 10 and the external device becomes larger, which contributes to improving the connection reliability between the housing 10 and the external device, and also makes the top surface structure of the housing 10 relatively flat, improving its appearance.

[0301] When the external device is the body 200 of the vehicle 1000, the inner area of ​​the body 200 on the top surface h forming the housing 10, the outer area of ​​the body 200 and the seal area hc are all installed on the same plane, ensuring that only vertical forces are received both inside and outside the body 200 of the housing 10, further reducing the load on the lateral structures of the vehicle 1000.

[0302] In some embodiments, referring to FIG. 14, when the mounting portion 13a3 includes at least one mounting hole k1, all of the mounting holes k1 penetrate the second region hb.

[0303] The above description of the mounting hole k1 can be referred to, but will not be repeated here. However, if the mounting hole k1 is provided so as to penetrate the second region hb, when connecting the housing 10 to an external device, the connecting material can be connected from the second region hb, which is relatively far from the top of the housing 10, to the top of the housing 10, thereby improving the connection strength between the housing 10 and the external device.

[0304] In some embodiments, referring to FIG. 14, there is a marginal distance between the outer edge of the sealing area hc close to the second region hb and the circumferential side wall n of the body 11.

[0305] The above description can be used as a reference for an explanation of the holes in the circumferential side wall n of the main body 11, but we will not go into detail here.However, since the outer edge of the sealing area hc close to the second region hb is not coplanar in the vertical direction with the plane on which the circumferential side wall n of the main body 11 is located, there is a certain preliminary distance between the outer edge of the sealing area hc and the outer edge of the top surface h1 of the main body 11.

[0306] When the seal 12 is assembled and not deformed, both side edges of the seal 12 overlap with the inner and outer side edges of the seal area hc, and when the seal 12 is sealed and connected to an external device, the seal 12 extends beyond the seal area hc on both sides, with one side extending beyond the seal area hc into the first region ha and the other side extending beyond the seal area hc into the second region hb.

[0307] A reserve distance is provided between the outer edge of the seal area hc near the second region hb and the axial side wall of the main body 11, ensuring sufficient deformation space for the seal 12 to deform, and preventing the seal 12 from extending beyond the top surface h1 of the main body 11 into other areas of the top surface of the housing 10 and interfering with structures in other areas.

[0308] In some embodiments, referring to FIGS. 11 and 13, the top surface h1 of the body 11 defines at least a portion of the top surface h that forms the housing 10.

[0309] The top surface h1 of the main body 11 is located at the top of the main body 11 and is a surface on one side that is spaced apart from the receiving cavity s. When the housing 10 includes both 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 together with the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. In this case, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can be arranged coplanarly, thereby increasing the contact area between the top surface h of the housing 10 and an external device, contributing to improved connection reliability between the housing 10 and the external device, and improving the appearance by making the top structure of the housing 10 relatively flat. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 may not be coplanar.

[0310] In other embodiments, the housing 10 may include other structures other than the main body 11 and the side beams 13, in which case the top surface h of the housing 10 is defined and formed together with 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.

[0311] As can be understood, the first region ha and the seal area hc are located on the top surface h1 of the main body 11, and the top surface h1 of the main body 11 can include other regions in addition to the first region ha and the seal area hc, and is not particularly limited here.

[0312] In some embodiments, with reference 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.

[0313] The top surface h1 of the main body 11 is divided into a first region ha, a seal area hc surrounding the outside of the first region ha, and a second region hb surrounding the outside of the seal area hc, and when the seal 12 in the seal area hc is compressed and deformed, one side edge of the seal 12 extends into the second region hb on the top surface h1 of the main body 11.

[0314] As can be understood, the second region hb on the top surface h1 of the main body 11 is a reserve distance between the outer edge of the sealing area hc close to the second region hb and the circumferential side wall n of the main body 11, and ensures sufficient deformation space for the deformation of the sealing portion 12 to prevent the sealing portion 12 from overflowing onto the side beam 13 beyond the top surface h1 of the main body 11 when it deforms.

[0315] In some embodiments, the mounting portion 13a3 is located in a second region hb defined by the top surface h2 of the side beam 13.

[0316] The mounting hole k1 is provided in the second region hb defined by the top surface h2, and has the beneficial effect of providing the mounting portion 13a3 at the top of the side beam 13, so a detailed description of the mounting hole k1 is omitted here.

[0317] When the housing 10 includes both 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 together with the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. A reserve distance is provided between the outer edge of the seal area hc near the second region hb and the axial side wall of the main body 11, ensuring sufficient deformation space for the seal 12 to deform and preventing the seal 12 from extending beyond the top surface h1 of the main body 11 onto the top surface h2 of the side beam 13 and interfering with the attachment of the attachment portion 13a3 on the side beam 13 when it deforms.

[0318] In some embodiments, referring to FIG. 14, the mounting portion 13a3 is arranged 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 two adjacent mounting portions 13a3 in the second region hb is 80 mm to 500 mm.

[0319] The first sub-beams 13a1 and the second sub-beams 13a2 are described above and will not be explained here. By providing two first sub-beams 13a1 extending in the first direction F1, two second sub-beams 13a2 extending in the second direction F2, and providing mounting portions 13a3 on the first sub-beams 13a1 and / or the second sub-beams 13a2, and extending the mounting portions 13a3 in the first direction F1 and / or the second direction F2, mounting and fixing to an external device can be uniformly achieved in multiple directions, further improving the connection between the external device and the housing 10.

[0320] Furthermore, by setting the distance between the geometric centers of the orthogonal projections of two adjacent mounting portions 13a3 in the second region hb and the distance between the geometric centers of adjacent mounting holes k1 to a certain range in a certain set direction, the set distance between the mounting holes k1 can be controlled in the extension direction of the first sub-beam 13a1 and the extension direction of the second sub-beam 13a2, thereby ensuring that an even force acts on the vehicle body 200.

[0321] As can be appreciated, if the housing 10 includes the intermediate passage beam 16, the intermediate passage beam 16 is located in the first region ha, such that the intermediate passage beam 16 is located in the intermediate region of the body 11.

[0322] In one embodiment, the housing 10 includes the main body 11 having the battery cavity s1 formed therein, and the high-pressure chamber 15 installed on the top of the main body 11, located in the first region ha, and surrounding the main body 11 to form the high-pressure cavity s2 by itself or together with the main body 11. Since the first region ha forms most of the top area of ​​the main body 11, by disposing the high-pressure chamber 15 in the first region ha, it is possible to improve the space utilization rate of the first region ha.

[0323] 3 and 4, the present application provides a battery 100 including the housing 10 described in any of the above embodiments and a battery unit 20 housed in the housing cavity s. The battery 100 of the present application includes the housing 10 described above, and therefore has all of the beneficial effects of the housing 10 described above, and descriptions thereof will be omitted here.

[0324] In some embodiments, the battery 100 further includes a high-pressure case (not shown), and the housing 10 is formed with a battery cavity s1 and a high-pressure chamber s2 that are independent of each other, with the battery cavity s1 housing the battery unit 20 and the high-pressure chamber s2 housing the high-pressure case.

[0325] The high-voltage case is an important safety barrier for the 100 battery packs, and is equipped with a high-voltage control system that is mainly used to turn on or off the high-voltage circuit according to the overall vehicle electronic control requirements, provide current and leakage detection terminals, realize controllable tape carrier cutoff when the external current of the 100 battery packs becomes excessive, realize high-voltage circuit cutoff when the external line of the 100 battery packs is short-circuited, prevent the 100 battery packs from catching fire, and easily cut off the high-voltage circuit when the 100 battery packs are being repaired.

[0326] In this case, the currents of all the battery units 20 are connected and aggregated via the high-voltage case, and safe electrical energy is supplied to the outside, thereby realizing a battery 100 that supplies safe external power. For the specific configuration of the high-voltage case, reference can be made to general settings in the art, and this application is not concerned with specific improvements to the high-voltage case.

[0327] According to some embodiments of the present application, the housing 10 has a housing cavity s that houses the battery unit 20 and a top surface h facing away from the housing cavity s, and the top surface h of the housing 10 is positioned so as to come into contact with an external device to which the battery 100 is attached. Among these, a wire-running portion 13a4 is formed on the outer wall of the housing 10, located below the top surface h of the housing 10 and forming a wiring space for passing a wire harness. By forming the wire-running portion 13a4 on the outer wall of the housing 10 and passing the wire harness through the wiring space formed by the wire-running portion 13a4, it is possible to prevent the wire harness from being pressed and deformed when the vehicle 1000 is pressed from the outside, thereby preventing unnecessary safety risks, and effectively protecting the wire harness.

[0328] 3 and 4, the present application provides a battery 100 including the housing 10 described in any of the above embodiments and a battery unit 20 housed in the housing cavity s. Since the battery 100 includes the housing 10 described above, it has all of the beneficial effects of the housing 10 described above, and the details thereof will not be described here.

[0329] In some embodiments, the battery 100 further includes a high-pressure case (not shown), and the housing 10 is formed with a battery cavity s1 and a high-pressure cavity s2 that are independent of each other, the battery cavity s1 accommodating the battery unit 20, and the high-pressure cavity s2 accommodating the high-pressure case.

[0330] The high-voltage case is an important safety barrier for the 100 battery packs, and is equipped with a high-voltage control system that is mainly used to turn on or off the high-voltage circuit according to the overall vehicle electronic control requirements, provide current and leakage detection terminals, realize controllable tape carrier cutoff when the external current of the 100 battery packs becomes excessive, realize high-voltage circuit cutoff when the external line of the 100 battery packs is short-circuited, prevent the 100 battery packs from catching fire, and easily cut off the high-voltage circuit when the 100 battery packs are being repaired.

[0331] In this case, the currents of all the battery units 20 are connected and aggregated by the high-voltage case, and safe electrical energy is supplied to the outside, thereby realizing a battery 100 that supplies safe external power. For the specific configuration of the high-voltage case, reference can be made to general settings in the art, and this application is not concerned with specific improvements to the high-voltage case.

[0332] 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 carrier 11a located at the top of the housing 10 and defining the storage cavity s, and the battery unit 20 is installed on the carrier 11a.

[0333] The description of the main body 11, the top surface of the housing 10, and the carrier 11a can be referred to above, so it will not be repeated here. In this case, the carrier 11a is a member capable of supporting the weight of the battery unit 20, and may be a carrier plate, carrier block, carrier sheet, carrier frame, etc., but is not specifically limited.

[0334] Specifically, the battery unit 20 is positioned below the carrier 11a, and the battery unit 20 and the carrier 11a share the force received from the top of the housing 10 of the battery 100, thereby increasing the rigidity of the top of the housing 10 of the battery 100.

[0335] In some embodiments, referring to Figures 10 and 20, the battery unit 20 is suspended from a carrier 11a.

[0336] The fact that the battery unit 20 is suspended from the carrier 11a means that the battery unit 20 is installed vertically below the carrier 11a and the weight of the battery unit 20 is borne by the carrier 11a. The battery unit 20 can be suspended from the carrier 11a by directly adhering the battery unit 20 to the underside of the carrier 11a, connecting the battery unit 20 to the carrier 11a via a fastener so that the battery unit 20 is positioned below the carrier 11a, or suspending the battery unit 20 from the carrier 11a via a hook or the like so that the battery unit 20 is positioned below the carrier 11a.

[0337] At this time, the battery unit 20 is suspended below the carrier 11a, and the bottom cover 11c is located at the bottom of the housing 10. When repairing the inside of the battery 100, the battery unit 20 can be exposed by removing the bottom cover 11c without removing the carrier 11a, making maintenance of the battery 100 more convenient. On the other hand, when repairing the battery 100, the battery unit 20 can be attached to and detached from the carrier 11a from below. In particular, when the carrier 11a is receiving force as at least a part of the chassis of the vehicle 1000, the battery unit 20 can be simply attached and detached from below the carrier 11a without removing the carrier 11a, making repair of the battery 100 easier.

[0338] In some embodiments, the battery cells 20 are glued to the carrier 11a.

[0339] Specifically, the battery unit 20 and the carrier 11a can be bonded with an adhesive such as an epoxy resin adhesive or an acrylic ester adhesive, but there are no particular limitations on the type of adhesive. In this case, the battery unit 20 and the carrier 11a are bonded together, which not only facilitates connection but also simplifies the structure of the battery 100.

[0340] FIG. 22 is a schematic diagram showing the structure of a battery unit 20 in some embodiments of the present application.

[0341] In some embodiments, referring to FIG. 22, the outer surface of the battery unit 20 facing the carrier 11a is a first outer surface m1, and the battery unit 20 includes an electrode terminal 21a arranged on an outer surface of the battery unit 20 other than the first outer surface m1.

[0342] As described above, the electrode terminals 21a are used for electrical connection with the electrode assemblies 23 inside the battery units 20 in order to output or input electrical energy to or from the battery units 20. At least a portion of the electrode terminals 21a protrudes from the battery units 20 and is electrically connected to the outside. The series and parallel connections between the electrode terminals 21a realize series and parallel connections between the battery units 20. The electrode terminals 21a are conductive and enable electrical transmission, and may be aluminum electrodes, copper electrodes, or the like.

[0343] The electrode terminal 21a is disposed on the outer surface of the battery unit 20 other than the first outer surface m1. The first outer surface m1 faces the carrier 11a and is a generally smooth surface without any irregularities such as the electrode terminal 21a or structures such as liquid injection holes. The first outer surface m1 is the outer surface on which the battery unit 20 faces upward when the battery unit 20 is suspended from the carrier 11a. Specifically, in one embodiment, the battery unit 20 includes the housing 22 and end cap 21 described above, and the housing 22 and end cap 21 form an internal environment in which the battery unit 20 accommodates the electrode assembly 23. The end cap 21 is located at one end of the housing 22, and the electrode terminal 21a is disposed on the end cap 21. In this case, any outer surface of the housing 22 can be the first outer surface m1 of the battery unit 20.

[0344] The electrode terminals 21a include a positive electrode terminal that is electrically connected to the positive electrode sheet in the electrode assembly 23, and a negative electrode terminal that is electrically connected to the negative electrode sheet in the electrode assembly 23. The positive electrode terminal and the negative electrode terminal may be arranged on the same outer surface of the battery unit 20 (as in a prismatic battery unit), or may be arranged on two different outer surfaces of the battery unit 20 (as in a cylindrical battery unit). When the positive electrode terminal and the negative electrode terminal are arranged on two different outer surfaces of the battery unit 20, the first outer surface m1 is a surface that is different from the two outer surfaces of the battery unit 20.

[0345] In addition to the individual batteries 20, the battery 100 typically includes components such as a sampling wire harness that electrically connects the individual batteries 20, a high-voltage wire harness, and a protective structure that protects the individual batteries 20. In this case, by arranging the electrode terminals 21a on a surface of the individual batteries 20 other than the first outer surface m1, when components such as the sampling wire harness, high-voltage wire harness, and protective structure are used for the electrode terminals 21a, the components can be arranged via the space between the individual batteries 20 and other structures of the main body 11 other than the carrier 11a (for example, the space between the individual batteries 20 and the bottom cover 11c and / or the space between the individual batteries 20 and the inner surface of the main body 11) without being constrained by the carrier 11a, making it easier to arrange the components. On the other hand, because the first outer surface m1 is a smooth surface, the first outer surface m1 and the carrier 11a can be brought into close contact, achieving close attachment of the individual batteries 20 and the carrier 11a. This eliminates the need to provide extra space between the individual batteries 20 and the carrier 11a, contributing to improved space utilization of the battery 100.

[0346] In some embodiments, referring to FIG. 22, the battery unit 20 has a second outer surface m2 placed opposite to the first outer surface m1, and the electrode terminal 21a is disposed on the second outer surface.

[0347] The second outer surface m2 is an outer surface on which the battery unit 20 is placed facing away from the first outer surface m1, and when the battery unit 20 is suspended from the carrier 11a, the second outer surface m2 faces the bottom cover 11c.

[0348] Furthermore, the battery unit 20 and the bottom cover 11c can be installed with a gap between them, which prevents external forces acting on the bottom cover 11c from being transmitted to the battery unit 20 and damaging the battery unit 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 part of the battery 100, stones and the like on the ground can easily fly to the bottom of the battery 100 and hit the bottom cover 11c while the vehicle 1000 is moving, but in this case, the buffer space can prevent external forces from being transmitted to the battery unit 20 and affecting it.

[0349] When the battery unit 20 is disposed at a distance from the bottom cover 11c, a buffer space is formed between the second outer surface m2 and the bottom cover 11c, where the electrode terminal 21a protrudes from the battery unit 20. A wire harness or a connecting piece connected to the electrode terminal 21a can be disposed within the buffer space. As described above, the buffer space provides a space that can prevent damage to the battery unit 20 caused by an external force that strikes the bottom cover 11c. This kills two birds with one stone by not only blocking the effects of external forces but also enabling the layout of the wire harness, etc. Furthermore, the space utilization of the buffer space and the battery 100 is improved.

[0350] In another aspect, the present application also provides a power consuming device, which includes the battery 100 provided in any of the above embodiments, and the battery 100 is used to provide electrical energy to the power consuming device. The introduction of the power consuming device can be referred to the above description, so it will be omitted here.

[0351] The power consuming device includes the battery 100 described above, and therefore has all the beneficial effects of the above-described embodiments, which will not be described here.

[0352] FIG. 1 is a schematic diagram of a battery 100 applied to a vehicle body 200 in some embodiments of the present application.

[0353] In some embodiments, the power consumption device includes a vehicle 1000, and the battery 100 is installed at the bottom of the body 200 of the vehicle 1000. The vehicle 1000 can be introduced in the above description, so it will not be described here.

[0354] The body 200 of the vehicle 1000 is the part of the vehicle 1000 used to carry passengers and cargo, and includes a driver's cab, passenger compartment, engine compartment, luggage compartment, etc. The body 200 generally includes an outer shell and doors, windows, trim, seats 300, air conditioning equipment, etc. arranged on the outer shell. The outer shell generally refers to a structure combining the main force-receiving elements of the vehicle 1000, such as rails, cross members, chassis, and pillars, and sheet metal parts connected to them. In the embodiments of the present application, the battery 100 being installed at the bottom of the body 200 mainly means that the battery 1000 is installed at the bottom of the outer shell.

[0355] In this case, by installing the battery 100 at the bottom of the vehicle body 200, it does not occupy space inside the vehicle body 200, which can contribute to reducing the volume and weight of the vehicle body 200.

[0356] In some embodiments, the battery 100 is connected to the vehicle body 200 through the top of the housing 10 , and the top of the housing 10 is positioned to form at least a portion of the chassis of the vehicle body 200 .

[0357] The chassis, which is part of the vehicle body 200, is a combination of four parts: the drive system, the running system, the steering system, and the braking system. It is used to support and mount the engine of the vehicle 1000 and its various components and assemblies, forms the overall shape of the vehicle 1000, receives the power of the engine, and ensures normal running.

[0358] The top of the bottom housing 10, where the chassis is located on the vehicle body 200, directly becomes at least a part of the chassis. That is, the top of the housing 10 is used to form at least a part of the chassis of the vehicle body 200. By integrating the top of the housing 10 integrally with the chassis of the vehicle body 200 in this manner, the space occupied by the gap between the conventional chassis and the battery 100 is divided into a space that expands the battery 100 within the battery 100, thereby improving the energy of the battery 100 and improving the driving range of the vehicle 100.

[0359] According to some embodiments of the present application, the power consumption device includes a vehicle 1000, and a battery 100 is installed at the bottom of a body 200 of the vehicle 1000. The battery 100 includes a housing 10 having a carrier 11a located at the top, and a battery unit 20 located within the housing 10 and suspended from the carrier 11a, with electrode terminals 21a of the battery unit 20 located on the outer surface of the battery unit 20 spaced apart from the carrier 11a, and the carrier 11a forming at least a part of the chassis of the vehicle 1000. In this case, since the battery 100 is suspended only from the carrier 11a, the strength of the carrier 11a can be improved, and further the strength of the top of the battery unit 20 can be improved, and when the carrier 11a is used as a chassis, a certain force-receiving requirement can be met. On the other hand, the electrode terminals 21a of the battery unit 20 are spaced apart from the carrier 11a, and the battery unit 20 can be directly attached to the carrier 11a, eliminating the need for a gap between the battery unit 20 and the carrier 11a. This unnecessary gap can be used to increase the mounting space for the battery unit 20, thereby improving the energy of the battery 100 and ultimately improving the driving range of the vehicle 1000.

[0360] The constituent elements of the above-described embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the constituent elements in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these constituent elements, all combinations should be considered to be within the scope described in this specification.

[0361] The above examples merely represent some examples of the present application, and although the description is specific and detailed, it should not be understood as limiting the scope of the patent of the present application. It should be noted that those skilled in the art may make some modifications and improvements without departing from the concept of the present application, and all of these fall within the scope of protection of the present application. Therefore, the scope of protection of the present application should be determined in accordance with the appended claims. [Explanation of symbols]
