Description

Technical Field

[0001] The present application relates to the field of battery technology, and in particular to a box, a battery, and an electrical device. Background Art

[0002] As new energy technologies mature, new energy vehicles are gradually entering the public eye. The core technology of new energy vehicles lies in batteries, whose safety and stability directly determine the performance of the entire vehicle.

[0003] A vehicle generally includes a vehicle body and a battery mounted on the vehicle body. A battery generally includes a housing and battery cells mounted within the housing. When the housing is mounted on the vehicle body, the sealing effect and connection stiffness between the two are likely to be poor. Summary of the Invention

[0004] In view of this, the present application provides a battery and an electrical device, aiming to improve the sealing effect and connection stiffness between the box and the vehicle.

[0005] In a first aspect, the present application provides a housing having a housing cavity for accommodating a battery cell and a top surface facing away from the housing cavity. The top surface of the housing is formed with a first region, a second region, and a sealing region located therebetween. The sealing region surrounds the first region and is used to mount a sealing member. The second region is configured with a mounting portion, and the battery is mounted to an external device via the mounting portion, so that the sealing member contacts the external device. The shortest distance between the geometric center of the orthographic projection of the mounting portion on the second region and the outer edge of the sealing region is 30 mm to 200 mm.

[0006] In this way, in the solution of the present application, it is possible to avoid the mounting force point of the mounting part being too far away from the seal, which on the one hand ensures the sealing effect of the seal on the interior of the vehicle body, and on the other hand reduces the mounting torque of each mounting part mounted on the vehicle body, effectively shortens the mounting force arm, and ensures the connection stiffness between the battery and the vehicle body.

[0007] In some embodiments, the shortest distance between the geometric center of the positive projection of the mounting part in the second area and the outer edge of the sealing area is 50mm-100mm, which can prevent the mounting force point of the mounting part from being too far away from the seal, thereby ensuring the sealing isolation effect of the seal on the first area and the second area, and at the same time, it can ensure the connection strength between the battery and the external device.

[0008] In some embodiments, the sealing area is coplanar with the second area. At this time, the mounting force point of each mounting part and the sealing area are located in the same plane and at the same height. The mounting force point and the sealing component only bear force in the vertical direction, thereby reducing the lateral structural force of the box and the vehicle body and improving the vehicle rigidity.

[0009] In some embodiments, the first area, the second area, and the sealing area are coplanar. In this case, the plane where the first area, the second area, and the sealing area are coplanar contacts the external device, and the contact area between the top surface of the box and the external device is large, which helps to improve the connection reliability between the box and the external device. At the same time, the top structure of the box is relatively flat and more aesthetically pleasing, and further reduces the lateral structural stress of the box.

[0010] In some embodiments, the mounting portion includes at least one mounting hole disposed on the top of the housing, the mounting hole extending through the second region. When connecting the housing to an external device, the connector can connect to the top of the housing from the second region relatively peripheral to the top of the housing, thereby enhancing the connection strength between the housing and the external device.

[0011] In some embodiments, the case further includes a seal installed in the sealing area. In this case, the battery case is sealed with an external device via the seal, sealing and isolating the first area from the second area, thereby achieving reliable sealing and low cost.

[0012] In some embodiments, the box includes a main body, the main body encloses a receiving cavity, a top surface of the main body defines at least a portion of the top surface of the box, and the first area and the sealing area are located on the top surface of the main body.

[0013] The top surface of the main body is divided into a first area and a sealing area surrounded by the first area. The first area can form a sealed vehicle body interior to ensure a sealed connection between the vehicle body and the main body.

[0014] In some embodiments, the box includes lateral beams. The main body has circumferential sidewalls extending around its top outer edge. The lateral beams are disposed on the circumferential sidewalls. The top surface of the main body and the top surfaces of the lateral beams together define the top surface of the box. The lateral beams disposed on the lateral circumferential walls of the main body reinforce the lateral structural strength of the main body, thereby improving the lateral crush resistance of the box and, in turn, the vehicle.

[0015] In some embodiments, the mounting portion is located in a second region defined by the top surface of the lateral beam. Placing the mounting portion on the lateral beam provides greater flexibility, as the lateral beam does not define a receiving cavity. Therefore, the mounting portion's impact on the sealing of the receiving cavity need not be considered when designing the mounting portion. Furthermore, since the lateral beam is located at the lateral edge of the box, placing the mounting portion on the lateral beam provides greater space and convenience when attaching the box to an external device.

[0016] In some embodiments, a reserved distance exists between an outer edge of the sealing zone close to the second region and a circumferential side wall of the main body.

[0017] A reserved distance is set between the outer edge of the sealing area close to the second area and the axial side wall of the main body, which can reserve sufficient deformation space for the deformation of the seal and prevent the seal from overflowing over the top surface of the main body to other areas on the top of the box and interfering with the structures in other areas.

[0018] In some embodiments, the lateral beam includes at least two sub-beams, which are sequentially spaced apart along the circumferential side wall. The top surface of each sub-beam defines a portion of the top surface of the lateral beam. The sub-beams are provided with a mounting portion.

[0019] The arrangement of the sub-beams improves the lateral extrusion capacity of the vehicle and the safety performance of the vehicle, and mounting parts can be arranged on the symmetrically arranged sub-beams to ensure uniform force on the mounting parts.

[0020] In some embodiments, the main body includes a supporting member and a frame, the frame encloses a cavity with at least the top end thereof penetrating therethrough, the supporting member covers the top end of the cavity, and the supporting member and the frame enclose at least a portion of the accommodating cavity; the lateral beams are arranged on the circumferential side walls defined by the frame.

[0021] In this way, a mounting base is formed to load the battery cells and side beams.

[0022] In a second aspect, the present application further provides a battery, comprising the above-mentioned box and a battery cell, wherein the battery cell is accommodated in the box.

[0023] In some embodiments, the box includes a main body, which encloses a receiving cavity. The main body includes a carrier located at the top of the box and used to define the receiving cavity. The battery cell is arranged on the carrier. The battery cell is arranged below the carrier and shares the load on the top of the battery box with the carrier, thereby improving the rigidity of the top of the battery box.

[0024] In some embodiments, the battery cells are suspended from a carrier, which is suspended below the carrier. The bottom cover is located at the bottom of the box. When repairing the battery's interior, the bottom cover can be removed to expose the battery cells without removing the carrier, making battery maintenance more convenient. Furthermore, when repairing the battery, the battery cells can be removed from the carrier from below. Especially when the carrier is at least part of the vehicle chassis and is subject to stress, the battery cells can be removed from the bottom of the carrier without removing the carrier, making battery repair more convenient.

[0025] In some embodiments, the battery cells are bonded to the carrier, and the battery cells are bonded to the carrier, which not only facilitates connection but also simplifies the structure of the battery.

[0026] In some embodiments, the outer surface of the battery cell facing the carrier is the first outer surface, and the battery cell includes electrode terminals, which are arranged on the outer surface of the battery cell other than the first outer surface. In this case, the electrode terminals are located on the outer surface of the battery cell other than the first outer surface, and various components connected to the electrode terminals (such as sampling harnesses, high-voltage harnesses, protective structures, etc.) can be arranged through the space between the battery cell and the bottom cover and / or the space between the battery cell and the inner side of the main body, which is more convenient for the arrangement of various components. Moreover, in this case, by connecting the first outer surface without electrode terminals to the carrier, the battery cell and the carrier can be fitted together, which can save space between the battery cell and the carrier and improve the space utilization of the battery.

[0027] In some embodiments, the battery cell has a second outer surface opposite the first outer surface, with the electrode terminals arranged on the second outer surface. In this case, a buffer space is provided between the second outer surface and the bottom cover, and the portion of the electrode terminal extending beyond the battery cell is located within this buffer space. This allows the wiring harness and connectors connected to the electrode terminals to be arranged within the buffer space. Furthermore, the buffer space prevents external forces striking the bottom cover from damaging the battery cell. Therefore, the buffer space not only blocks external forces but also facilitates the layout of wiring harnesses, achieving two goals at once.

[0028] In a third aspect, the present application also provides an electrical device, comprising the above-mentioned battery, which is used to provide electrical energy to the electrical device.

[0029] In some embodiments, the electrical device includes a vehicle, and the battery is disposed at the bottom of the vehicle body. In this case, disposing the battery at the bottom of the vehicle body does not occupy space inside the vehicle body, thereby helping to reduce the volume and weight of the vehicle body.

[0030] In some embodiments, the battery is connected to the vehicle body via the top of the housing, and the top of the housing is configured to form at least a portion of the vehicle chassis. In this case, the space traditionally occupied by the gap between the chassis and the battery can be allocated to the battery, thereby increasing the battery's energy and, in turn, the vehicle's range.

In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0059] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments.

[0063] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; internal connections between two components or interactions between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0064] Currently, market developments indicate that batteries are increasingly being used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As battery applications continue to expand, market demand is also growing.

[0065] The inventors noted that when connecting a battery box to a vehicle body, a sealing structure is typically provided to achieve a sealed connection between the box and the vehicle body, and a fixing structure is also provided to secure the box and the vehicle body. However, the fixing structure and the sealing structure are located at different positions, resulting in the fixing force provided by the fixing structure being unable to effectively secure the seal. This results in the sealing effect of the seal being unable to be guaranteed, and in turn, the rigidity of the connection between the box and the vehicle body being poor.

[0066] In order to improve the sealing effect and connection stiffness between the box and the vehicle body, the applicant has found that the setting position and setting distance of the fixed structure and the sealing structure can be controlled to ensure that the fixed structure reinforces the sealing of the seal, thereby ensuring the sealing effect while improving the connection stiffness between the box and the vehicle body.

[0067] Based on the above considerations, in order to improve the sealing effect and connection stiffness between the box and the vehicle, the inventors have conducted in-depth research and designed a box for batteries, which can accommodate battery cells inside. The box has a top surface facing away from the accommodating cavity, and the top surface is divided into a first area, a sealing area and a second area. The sealing area is used to install a seal and the seal is in sealing contact with the vehicle body. The second area is constructed with a mounting portion and is fixedly connected to the vehicle body through the mounting portion, and the shortest distance between the geometric center of the positive projection of the mounting portion in the second area and the outer edge of the sealing area is controlled to be 30mm-200mm, which can avoid the mounting force point of the mounting portion being too far away from the seal. On the one hand, it ensures the sealing effect of the seal on the interior of the vehicle body, and on the other hand, it reduces the mounting torque of each mounting portion mounted on the vehicle body, effectively shortens the mounting force arm, and ensures the connection stiffness between the battery and the vehicle body.

[0068] The batteries disclosed in the embodiments of this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. A power supply system comprising the batteries disclosed in this application can be constructed. The mounting body referred to in this application is a structure for mounting a battery in an electrical device.

[0069] The present invention provides an electric device that uses a battery as a power source. The electric device may be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery-powered vehicle, an electric car, a ship, a spacecraft, etc. The electric toy may include a fixed or mobile electric toy, such as a game console, an electric car toy, an electric ship toy, and an electric airplane toy, etc. The spacecraft may include an airplane, a rocket, a space shuttle, and a spacecraft, etc.

[0070] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an electrical device according to an embodiment of the present application.

[0071] Please refer to Figure 1 , Figure 1 A schematic structural diagram of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 100 is provided inside the vehicle 1000, and the battery 100 can be provided at the bottom, head or tail of the vehicle 1000. The battery 100 can be used to power the vehicle 1000, for example, the battery 100 can serve as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller and a motor, and the controller is used to control the battery 100 to power the motor, for example, for starting, navigating and operating power requirements of the vehicle 1000 during driving.

[0072] In some embodiments of the present application, the battery 100 can serve not only as an operating power source for the vehicle 1000, but also as a driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0073] Please refer to Figure 2 , Figure 2 The schematic diagram of the structure of the vehicle 1000 provided in some embodiments of the present application. The battery cell 20 refers to the smallest unit that constitutes the battery 100. Figure 2 As shown, the battery cell 20 includes an end cap 21 , a housing 22 , an electrode assembly 23 and other functional components.

[0074] The end cap 21 is a component that covers the opening of the housing 22 to isolate the internal environment of the battery cell 20 from the external environment. The shape of the end cap 21 can be adapted to the shape of the housing 22 to fit the housing 22. Optionally, the end cap 21 can be made of a material with a certain hardness and strength (such as an aluminum alloy). This prevents the end cap 21 from deforming when subjected to compression or collision, thereby providing the battery cell 20 with greater structural strength and improved safety. The end cap 21 can be provided with functional components such as electrode terminals 21a. The electrode terminals 21a can be used to electrically connect to the electrode assembly 23 for inputting or outputting electrical energy from the battery cell 20. In some embodiments, the end cap 21 can also be provided with a pressure relief mechanism for relieving internal pressure when the internal pressure or temperature of the battery cell 20 reaches a threshold. The end cap 21 can also be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this embodiment of the present application does not impose any particular limitations on this. In some embodiments, an insulating member may be provided inside the end cap 21 to isolate the electrical connection portion 11a2 in the housing 22 from the end cap 21 to reduce the risk of short circuit. For example, the insulating member may be made of plastic, rubber, or the like.

[0075] The housing 22 is a component that cooperates with the end cap 21 to form the internal environment of the battery cell 20. This internal environment can be used to accommodate the electrode assembly 23, electrolyte, and other components. The housing 22 and end cap 21 can be separate components. An opening can be provided in the housing 22, and the end cap 21 is placed over the opening to form the internal environment of the battery cell 20. Alternatively, the end cap 21 and housing 22 can be integrated. Specifically, the end cap 21 and housing 22 can form a common connection surface before other components are inserted into the housing. When the interior of the housing 22 needs to be enclosed, the end cap 21 is placed over the housing 22. The housing 22 can have a variety of shapes and sizes, such as a rectangular parallelepiped, a cylindrical shape, or a hexagonal prism. Specifically, the shape of the housing 22 can be determined based on the specific shape and size of the electrode assembly 23. The housing 22 can be made of a variety of materials, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this embodiment of the present application does not impose any particular limitations on this.

[0076] The electrode assembly 23 is a component in the battery cell 20 where electrochemical reactions occur. One or more electrode assemblies 23 may be contained in the housing 22. The electrode assembly 23 is mainly formed by winding or stacking positive and negative electrode sheets, and a separator is usually provided between the positive and negative electrode sheets. The parts of the positive and negative electrode sheets with active materials constitute the main body 11 of the electrode assembly 23, and the parts of the positive and negative electrode sheets without active materials constitute each other. The positive electrode tab and the negative electrode tab may be located together at one end of the main body 11 or respectively at both ends of the main body 11. During the charge and discharge process of the battery, the positive electrode active material and the negative electrode active material react with the electrolyte, and the tabs connect the electrode terminals 21a to form a current loop.

[0077] Figure 3 This is a schematic exploded view of a battery 100 provided in some embodiments of the present application. The battery 100 includes a battery cell 20 and a case 10 . The case 10 has a receiving cavity s for receiving the battery cell 20 .

[0078] In the battery 100, there may be multiple battery cells 20, and the multiple battery cells 20 may be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to the multiple battery cells 20 being connected both in series and in parallel. The multiple battery cells 20 may be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery cell 20 may be housed within the housing 10. Of course, the battery 100 may also be a battery module formed by first connecting multiple battery cells 20 in series, in parallel, or in a hybrid connection, and then the multiple battery modules may be connected in series, in parallel, or in a hybrid connection to form an entire battery cell, which is then housed within the housing 10. The battery 100 may also include other structures. For example, the battery 100 may further include a busbar component for electrically connecting the multiple battery cells 20. Each battery cell 20 may be a secondary battery or a primary battery; it may also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited thereto. The battery cell 20 may be cylindrical, flat, rectangular, or have other shapes.

[0079] The box body 10 can be in various shapes, such as a cylinder, a cuboid, etc., and the specific structure of the box body 10 can adopt various structural methods.

[0080] According to some embodiments of this application, please refer to Figure 3 The present application provides a box 10 for a battery 200. The box 10 has a receiving cavity s for receiving a battery cell 20. The box 10 is used to provide a receiving space for the battery cell 20. The box can adopt a variety of structures. In some embodiments (such as Figure 3 As shown in FIG. 1 , the housing may include a first portion 10A and a second portion 10B, which cover each other and together define a storage space for accommodating battery cells. The second portion 1 may be a hollow structure with one end open, and the first portion 10A may be a plate-like structure, with the first portion 10A covering the open side of the second portion, so that the first portion 10A and the second portion 10B together define a storage space. The first portion 10A and the second portion 10B may also be hollow structures each with one end open, with the open side of the first portion 10A covering 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 various shapes, such as a cylinder, a rectangular parallelepiped, etc.

Figure 6 Schematic diagram of a partial structure of the battery 100 in some embodiments of the present application. Figure 7 for Figure 6 The enlarged view of point B in the structure shown, Figure 8 for Figure 6A top view of the structure, Figure 9 for Figure 6 A side view of the structure, Figure 10 for Figure 9 A cross-sectional view of the structure shown at CC.

[0082] In some embodiments, please refer to Figure 4 The battery 100 is mounted on an external device via the top of the box 10 .

[0083] The top of the housing 10 includes the top surface h of the housing 10 and other structures disposed on the top surface h of the housing 10. The top surface h of the housing 10 refers to the upper vertical surface of the housing 10 when in use. Other structures disposed on the top surface h of the housing 10 include, but are not limited to, connectors (such as bolts, rivets, etc.) connecting the top surface h of the housing 10 to external devices and sealing structures (such as sealing strips, etc.) that seal the housing 10 from external devices.

[0084] The external device refers to a device used to mount the housing 10. This external device can be the aforementioned partial structure of the electrical device used to mount the housing 10, or it can be the remaining structure of the electrical device that, together with the battery 100, forms the electrical device. For example, if the electrical device is a vehicle 1000, the external device can be the vehicle body 200 of the vehicle 1000. The battery 100 can be mounted on the bottom of the vehicle body 200 and attached to the vehicle body 200 via its top.

[0085] At this time, the battery 100 is installed on the external device through the top of the box 10. Compared with the arrangement in which the box 10 is located at the bottom of the external device, the connection structure between the box 10 and the external device is smaller in size, lower in cost and more compact.

[0086] Of course, in other embodiments, the battery 100 may also be installed on an external device via the bottom, side, or other locations of the box body 10 .

[0087] In some embodiments, please refer to Figure 4 The box body 10 includes a main body 11, and the main body 11 encloses a receiving cavity s.

[0088] The main body 11 can be an integrally formed structure, or it can be formed by assembling a plurality of parts. Understandably, the main body 11 is a hollow shell-like structure, which itself encloses a receiving cavity s. Specifically, without limitation, the main body 11 can be formed by assembling a first sub-part (not shown) and a second sub-part (not shown). In one example, the first sub-part encloses a receiving cavity s with one end open, and the second sub-part covers the opening of the receiving cavity s. In another example, the first sub-part encloses a first space with one end open, and the second sub-part encloses a second space with one end open, and the two openings of the first sub-part and the second sub-part cover each other to form a receiving cavity s consisting of the first space and the second space. The first sub-part and the second sub-part can be welded, clamped, fastened, etc. The first sub-part and the second sub-part can be made of plastic, metal, or other materials.

[0089] In some embodiments, please refer to Figure 4 , the top of the main body 11 forms at least a part of the top of the box body 10.

[0090] The top of the main body 11 refers to the structure located at the uppermost position of the main body 11 in the vertical direction. The uppermost position of the main body 11 is the uppermost position of the box body 10, so that the top of the main body 11 forms at least a part of the top of the box body 10. When the top of the main body 11 forms the entire top of the box body 10, the top of the main body 11 is the top of the box body 10, and the entire top of the box body 10 participates in the definition of the accommodating cavity s. When the top of the main body 11 forms a part of the top of the box body 10, the top of the box body 10 also has another part that does not participate in the definition of the accommodating cavity s, such as the lateral beam 13 described below, which will be described in detail below.

[0091] When the battery 100 is installed on an external device via the top of the box 10, the top of the main body 11 is also located at the position closest to the external device in the battery 100. The distance between the top of the main body 11 and the external device refers to the distance between the highest point of the top of the main body 11 and the external device located above it in the vertical direction.

[0092] Understandably, please refer to Figure 6 The main body 11 has a circumferential side wall n arranged around the top outer edge of the main body 11.

[0093] The main body 11 has a top at the uppermost position in the vertical direction, and naturally also has a bottom at the lowermost position, wherein the bottom can be a bottom surface and a structure arranged on the bottom surface, or a bottom opening.

[0094] The outer surface of the structure, sandwiched between the top and bottom portions and facing away from the accommodating cavity s, forms a circumferential sidewall n. The plane of the circumferential sidewall n extends in a direction that intersects the plane of the top portion. The circumferential sidewall n can be annular, quadrilateral, or other shapes formed by connecting multiple wall segments end-to-end. Details are provided below.

[0095] Understandably, please refer to Figure 6 The box body 10 also has a top surface h facing away from the accommodating cavity s.

[0096] The top surface h of the box body 10 is located on the surface of the top side of the box body 10 facing away from the accommodating cavity s. When the battery 100 is assembled to an external device through the top of the box body 10, the top surface h is arranged facing the external device and forms the position of the battery 100 closest to the external device.

[0097] In some embodiments, please refer to Figure 6 The top surface h of the housing 10 is configured to be in contact with an external device (not shown) on which the battery 100 is mounted.

[0098] The battery 100 is installed on the external device through the top of the box body 10, and the surface of the box body 10 facing away from the accommodating cavity s is in contact with the external device, so that the battery 100 is tightly connected to the external device. Compared with the arrangement in which the top surface h of the box body 10 does not contact the external device, the connection structure between the box body 10 and the external device is smaller in size, lower in cost and more compact.

[0099] In some embodiments, please refer to Figure 6 The top of the housing 10 is provided with a mounting portion 13a3, and the battery 100 is mounted on an external device via the mounting portion 13a3.

[0100] The mounting portion 13a3, as a part of the top of the box body 10, does not participate in the definition of the accommodating cavity s. The mounting portion 13a3 refers to a special structure provided on the top of the box body 10 for connecting to a connector (such as a bolt, rivet, etc.) of an external device. One end of the connector can be connected to the mounting portion 13a3, and the other end can be connected to the external device to fix the battery 100 to the external device. It can be understood that the top of the main body 11 is at least a part of the top of the box body 10. The mounting portion 13a3 can be provided on the top of the main body 11, or on other structures that form the top of the box body 10 (such as the top of the lateral beam 13 mentioned below).

[0101] When the battery 100 is mounted on an external device through the mounting portion 13a3, the top surface h of the box body 10 is in contact with the external device, which not only improves the connection strength but also ensures the compactness of the connection structure between the box body 10 and the external device.

[0102] The mounting portion 13a3 may also have a connecting function (such as a lifting ring), and a corresponding connecting member (such as a hook) may be provided on the external device to directly connect to the mounting portion 13a3. In other embodiments, the connecting member may not be provided, and the mounting portion 13a3 may be directly connected to the external device through other methods, including but not limited to snap-on connection, plug-in connection, threaded connection, riveting, welding, bonding, etc., which are not specifically limited in this application.

[0103] In some embodiments, please refer to Figure 6 The mounting portion 13a3 includes at least one mounting hole k1 provided on the top of the box body 10.

[0104] The mounting holes k1 can be formed on the top of the box body 10 by drilling. All mounting holes k1 have holes and openings connected to both ends of the holes. The holes and the openings connected to both ends of the holes allow the connector to pass through themselves and be fixed to the structure with the mounting holes k1, thereby connecting the external device to the top of the box body 10 through the connector.

[0105] The connecting member can be a rivet, with a fixing hole 11c3 provided at the location of the external device corresponding to the mounting hole k1. The rivet passes through the fixing hole 11c3 and the mounting hole k1, and then a nut secures the two. Alternatively, the connecting member can be a screw, with the mounting hole k1 being a threaded hole. The screw passes through the mounting hole k1 and is threadedly connected to the housing 10.

[0106] Specifically, all mounting holes k1 can be arranged to extend vertically to vertically secure the battery 100 to the bottom of the external device. It is understood that in order to achieve a stable connection between the top of the housing 10 and the external device and uniform force between the two, the location and spacing of all mounting holes k1 can be controlled, as detailed below.

[0107] It is understandable that, in addition to the mounting hole k1 , the mounting portion 13 a 3 may also include other structures capable of achieving mounting, such as a hook.

[0108] In some embodiments, please refer to Figure 4 and Figure 6 The main body 11 includes a carrier 11a and a frame 11b. The frame 11b encloses a cavity with at least its top being passed through. The carrier 11a covers the top of the cavity. The carrier 11a and the frame 11b enclose at least part of the accommodating cavity s.

[0109] The frame 11b itself encloses a cavity with at least its top being provided through it, and the supporting member 11a covers the top of the cavity, that is, the supporting member 11a is located at the top of the box body 10 and is used to define the accommodating cavity s. The frame 11b and the supporting member 11a can be made of the same material, such as aluminum alloy, copper alloy, steel, plastic, etc. Of course, the frame 11b, the supporting member 11a and the bottom cover 11c can also be made of different materials, which is not limited to the specific ones. In the vertical projection, the frame 11b can be rectangular, circular, polygonal, etc., which is not limited to the specific ones. The supporting member 11a can be a supporting plate, a supporting sheet, a supporting block, etc.

[0110] The top surface h1 of the main body 11 can be entirely formed by the top surface of the carrier 11a, in which case the frame 11b is entirely located below the carrier 11a. The top surface h1 of the main body 11 can also be formed by the top surface of the carrier 11a and the top surface of the frame 11b together, in which case the carrier 11a is located inside the frame 11b, and the top surface of the carrier 11a and the top surface of the frame 11b can be either coplanar or non-coplanar.

[0111] The carrier 11a and the frame 11b are fixedly connected or integrally formed. The carrier 11a and the frame 11b are integrally formed by injection molding, die casting, forging, cold pressing, hot pressing, etc. The carrier 11a and the frame 11b can be fixedly connected by fasteners, snap-fit ​​connection, welding, bonding, hot melt connection, etc.

[0112] The circumferential side wall n of the main body 11 is mainly formed by the circumferential side wall n of the frame 11 b. The circumferential side wall n of the frame 11 b is an outer surface arranged around the carrier 11 a and facing away from the cavity defined by the frame 11 b.

[0113] In some embodiments, please refer to Figure 4 and Figure 5 The main body 11 further includes a bottom cover 11 c , which, together with the carrier 11 a and the frame 11 b , forms a receiving cavity s for receiving the battery cell 20 .

[0114] It is understandable that the cavity of the frame 11b also passes through the bottom of the frame 11b. The bottom cover 11c covers the bottom of the frame 11b and forms the accommodating cavity s of the box body 10 together with the frame 11b and the carrier 11a.

[0115] Specifically, the bottom cover 11c may be, but is not limited to, a plate-like structure, a block-like structure, or the like, and may be a flat plate, a curved plate, or the like. When the battery cell 20 is located in the receiving cavity s, the battery cell 20 may be disposed on the bottom cover 11c and / or the carrier 11a and / or the frame 11b.

[0116] The bottom cover 11c and the frame 11b can be fixed together by welding, hot-melt connection, bonding, fastening connection, snap connection, etc. Among them, fastening connection refers to connection achieved by fixing members 11c4, and the fixing members 11c4 include components such as bolts, latches, rivets, pins, screws, etc. Among them, snap connection refers to fixing achieved by a snap-fit ​​structure, for example, the bottom cover 11c has a hook and the frame 11b has a slot, and when the hook is engaged in the slot, the bottom cover 11c and the frame 11b can be snap-fitted and fixed. Of course, the connection methods between the bottom cover 11c and the frame 11b are not limited to these, and are not exhaustively listed in this application.

[0117] At this time, based on the frame 11b, the carrier 11a and the bottom cover 11c are respectively connected to the two ends of the frame 11b in the vertical direction to form the accommodating cavity s of the battery 100. The structure of the main body 11 is relatively simple.

[0118] In some embodiments, please refer to Figure 4 and Figure 5 The bottom cover 11c has a cover portion 11c1 and a mounting portion 11c2. The mounting portion 11c2 is connected to the edge of the cover portion 11c1. The cover portion 11c1 is used to define the accommodating cavity s. The mounting portion 11c2 is connected to the frame 11b.

[0119] The cover 11c1 is used to define the accommodating cavity s, which means that the cover 11c1, the carrier 11a, and the frame 11b together enclose the accommodating cavity s, and the mounting portion 11c2 is connected to the frame 11b and does not participate in the definition of the accommodating cavity s. The cover 11c1 can be a plate-shaped or block-shaped component, a flat plate-shaped component, or a curved plate-shaped component, which is not specifically limited. Figure 4 and Figure 5 As can be seen, the mounting portion 11c2 encloses the edge of the cover portion 11c1, meaning that the mounting portion 11c2 is continuously disposed along the edge of the cover portion 11c1, forming a closed end-to-end connection. Understandably, in vertical projection, the mounting portion 11c2 has a certain width, which provides an appropriate contact area with the frame 11b, facilitating positioning and installation between the mounting portion 11c2 and the frame 11b.

[0120] The cover portion 11c1 and the mounting portion 11c2 can be integrally formed. When the bottom cover 11c is made of metal (such as aluminum, iron, stainless steel, etc.), the cover portion 11c1 and the mounting portion 11c2 can be integrally formed by die casting, forging, hot pressing, cold pressing, etc. When the bottom cover 11c is made of plastic (such as polypropylene, polyethylene, ABS (Acrylonitrile Butadiene Styrene plastic), etc.), the cover portion 11c1 and the mounting portion 11c2 can be integrally formed by injection molding. The cover portion 11c1 and the mounting portion 11c2 can also be formed separately and then connected together. When the cover portion 11c1 and the mounting portion 11c2 are made of metal, the cover portion 11c1 and the mounting portion 11c2 can be welded or bonded together. When the cover portion 11c1 and the mounting portion 11c2 are made of plastic, the cover portion 11c1 and the mounting portion 11c2 can be bonded together. Of course, the cover portion 11c1 and the mounting portion 11c2 may also be fixedly connected together by other means such as snapping, riveting, etc.

[0121] The cover portion 11c1 and the mounting portion 11c2 can be located in the same plane. Specifically, optionally, the two surfaces of the cover portion 11c1 and the mounting portion 11c2 facing the carrier 11a are located in the same plane, and / or the two surfaces of the cover portion 11c1 and the mounting portion 11c2 facing away from the carrier 11a are located in the same plane. When the two surfaces of the cover portion 11c1 and the mounting portion 11c2 facing the carrier 11a and the two surfaces facing away from the carrier 11a are located in the same plane, the cover portion 11c1 and the mounting portion 11c2 can form a flat bottom cover 11c.

[0122] The cover portion 11c1 and the mounting portion 11c2 may not be located in the same plane. Specifically, the cover portion 11c1 may be recessed relative to the mounting portion 11c2 toward the support member 11a, or the cover portion 11c1 may be protruding relative to the mounting portion 11c2 away from the support member 11a, without specific limitation. The thickness of the cover portion 11c1 and the mounting portion 11c2 may be equal or different, without specific limitation.

[0123] At this time, the bottom cover 11c defines the accommodating cavity s via the cover portion 11c1 and is connected to the frame 11b via the mounting portion 11c2, with a clear structure and convenient installation.

[0124] It is understood that when the bottom cover 11c is detachably connected to the frame 11b, the bottom cover 11c is detachably connected to the frame 11b via the mounting portion 11c2, i.e., the mounting portion 11c2 is detachably connected to the frame 11b. The mounting portion 11c2 can be detachably connected to the frame 11b by simply setting the portion of the bottom cover 11c that is detachably connected to the frame 11b as the mounting portion 11c2.

[0125] In some embodiments, the mounting portion 11c2 is detachably connected to the frame 11b.

[0126] Specifically, the bottom cover 11c also includes a fixing hole 11c3 provided on the mounting portion 11c2. The fixing member 11c4 penetrates the fixing hole 11c3 on the mounting portion 11c2 and is then fastened to the frame 11b. The fixing hole 11c3 is a through hole that vertically extends through the mounting portion 11c2. Specifically, the fixing hole 11c3 can be a smooth through hole (such as when the fixing member 11c4 is a rivet), a threaded through hole (such as when the fixing member 11c4 is a screw), or another through hole (such as a hexagonal hole, a square hole, a waist-shaped hole, etc.). The specific form of the fixing hole 11c3 depends on the specific form and specific setting method of the fixing member 11c4, and will not be elaborated here.

[0127] In some embodiments, please refer to Figure 6 、 Figure 8 and Figure 9 The box body 10 includes a lateral beam 13 , which is provided on the circumferential side wall n of the main body 11 .

[0128] The lateral beams 13 are beam structures provided on the circumferential sidewalls n of the main body 11 to reinforce the main body 11. It is understood that the lateral beams 13 are located outside the main body 11. Specifically, the main body 11 and the lateral beams 13 are integrally connected to form a single unit, or they can be connected by assembly. Integral connection methods include, but are not limited to, welding, integral molding, and welding. Assembly connection methods include, but are not limited to, snap-fitting and fastening.

[0129] The lateral beams 13 can be arranged along the entire circumferential sidewall n of the main body 11, or only along a portion of the circumferential sidewall n. Without limitation, the lateral beams 13 are arranged around the circumferential sidewall n of the main body 11, thereby reinforcing the strength of the main body 11 in multiple lateral directions. Specifically, the lateral beams 13 can be arranged continuously or intermittently around the circumferential sidewall n of the main body 11. When arranged continuously, the lateral beams 13 can be annular; when arranged intermittently, the lateral beams 13 can include multiple beam sections spaced apart around the circumferential sidewall n of the main body 11.

[0130] In an actual application scenario, the box 10 is used for the battery 100 and the battery 100 is applied to the vehicle 1000. The top of the box 10 is installed on the vehicle 1000 and the top of the box 10 forms the chassis structure of the vehicle 1000. When the battery 100 box 10 is used as the chassis of the vehicle 1000, the lateral structure of the box 10 is easily squeezed by external impact (such as stones flying while the vehicle 1000 is driving and hitting the lateral position of the box 10, or being hit by other vehicles 1000). At this time, a lateral beam 13 is provided on the lateral peripheral wall of the main body 11. The lateral beam 13 can strengthen the lateral structural strength of the main body 11, thereby improving the lateral anti-extrusion ability of the box 10, and also improving the lateral anti-extrusion ability of the vehicle 1000, thereby improving the safety of the vehicle 1000.

[0131] It can be understood that when the main body 11 includes the aforementioned supporting member 11 a and the frame 11 b , the lateral beam 13 is disposed on the circumferential side wall n defined by the frame 11 b .

[0132] The cavity formed by frame 11b primarily constitutes the housing 10's accommodating chamber s. Because accommodating chamber s has a certain height to accommodate multiple battery cells 20, frame 11b also has a certain height, resulting in a relatively large area of ​​the circumferential sidewalls n of frame 11b. In this case, lateral beams 13 are positioned along the circumferential sidewalls n defined by frame 11b, providing greater flexibility in their installation method, installation area, and layout.

[0133] In the embodiment, the lateral beam 13 and the frame 11b are fixedly connected or integrally formed. The lateral beam 13 and the frame 11b can be fixedly connected by welding, welding, riveting, threading, etc., or formed into one piece by one-piece processing (such as stamping or die casting).

[0134] When the lateral beams 13 and the frame 11b are integrally formed, the assembly steps of the box 10 can be reduced, speeding up the production process of the box 10. When the lateral beams 13 and the frame 11b are fixedly connected, the molding process of the lateral beams 13 and the frame 11b is easier, which can reduce the processing cost of the box 10.

[0135] In some embodiments, please refer to Figure 10 The lateral beam 13 includes at least two sub-beams 13a, which are sequentially spaced along the circumferential sidewall n. The sub-beams 13a are the basic units that make up the lateral beam 13. By setting the positions of the sub-beams 13a, the position of the lateral beam 13 on the circumferential sidewall n of the main body 11 can be flexibly arranged.

[0136] The lateral beam 13 is formed by at least two sub-beams 13a arranged at intervals along the circumferential side wall n of the main body 11, which means that at least two sub-beams 13a are arranged at intervals along the extension direction of the circumferential side wall n to form an encircling form surrounding the main body 11, so as to strengthen the strength of the main body 11 from multiple lateral directions of the main body 11.

[0137] The sub-beams 13a can have various structural forms, and the structures of the sub-beams 13a can be the same or different. For example, the sub-beam 13a is a solid beam extending longitudinally. Another example is a hollow beam extending longitudinally. The cross-sectional shape of each sub-beam 13a can be H-shaped, U-shaped, or other structural forms.

[0138] At this time, the lateral beam 13 is formed by a combination of multiple sub-beams 13a, and the arrangement of the lateral beam 13 is more flexible. At the same time, each sub-beam 13a can be installed one by one during installation. Compared with the integral lateral beam 13, the positioning during the installation process is more convenient and more labor-saving.

[0139] In some embodiments, continue to refer to Figure 10 At least one sub-beam 13 a includes an upper arm beam 131 and a lower arm beam 132 . The upper arm beam 131 and the lower arm beam 132 are spaced apart from each other and are both connected to the main body 11 .

[0140] The up-down direction corresponds to the direction of the top and bottom of the main body 11, that is, the upper arm beam 131 is close to the top of the main body 11, and the lower arm beam 132 is close to the bottom of the main body 11. It can be understood that both the upper arm beam 131 and the lower arm beam 132 extend along the circumference of the main body 11 and conform to the circumferential sidewall n of the main body 11. The upper arm beam 131 and the lower arm beam 132 are arranged at intervals and connected by the main body 11. A channel can be formed in the middle of the gap between the two, which can serve as a weight-reducing structure or a structure for wiring harnesses.

[0141] At this time, the structure of the main body 11 is strengthened by the upper arm beam 131 and the lower arm beam 132. Since the upper arm beam 131 and the lower arm beam 132 are arranged separately, the impact force on the box body 10 can be dispersed, so that the external force on each part of the box body 10 is relatively uniform. At the same time, the upper arm beam 131 and the lower arm beam 132 are arranged in a vertically spaced manner, so that the sub-beam 13a can withstand the compression in the front-to-back direction or the left-to-right direction of the vehicle 1000, which is more suitable for the actual use conditions of the vehicle 1000. In addition, the spacing between the upper arm beam 131 and the lower arm beam 132 can reduce the weight of the box body 10 and achieve other functions.

[0142] In other embodiments, an intermediate beam (not shown) may be 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 . This can further strengthen the structural strength of the sub-beam 13a and improve the lateral anti-extrusion capability of the box body 10 .

[0143] 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 with a hollow structure inside, that is, there is a space inside the beam that is not filled with any solid material. In this case, the upper arm beam 131 and the lower arm beam 132 are hollow beam structures, which can not only reduce their own weight, but also reduce the problem of high energy consumption caused by the heavy weight of the battery 100 formed by the box body 10 when it is used in electrical devices such as vehicles 1000. In addition, the hollow beam structure can consume lateral extrusion force through the space inside it, reducing the degree of damage to the battery 100 when it is subjected to lateral extrusion.

[0144] In some embodiments, please refer to Figure 6 The circumferential side wall n includes at least two first wall segments n1 extending along the first direction F1 and separated from each other; the at least two sub-beams 13a include two first sub-beams 13a1, which are respectively arranged on the two first wall segments n1 and both extend along the first direction F1.

[0145] In a practical application, when the battery 100 formed by the housing 10 is used in a vehicle 1000 and the top of the housing 10 forms the chassis of the vehicle 1000, the first direction F1 may correspond to the front-to-back direction of the vehicle 1000. The first wall segments n1 of the circumferential side walls n of the main body 11 correspond to the left and right circumferential side walls n of the battery 1000. The first wall segments n1 extend along the first direction F1, i.e., along the front-to-back direction of the vehicle 1000. The two first wall segments n1 are spaced apart in the left-to-right direction of the vehicle 1000. Sub-beams 13a are provided on both first wall segments n1, and each sub-beam 13a extends in the same direction as each first wall segment n1.

[0146] The sub-beams 13a on each first wall segment n1 can have the same structure, ensuring consistent crush resistance on both the left and right sides of the vehicle 1000. Furthermore, the sub-beams 13a on the first wall segment n1 include the upper arm beam 131 and lower arm beam 132 mentioned in the above embodiment. In this case, the sub-beams 13a have a stronger crush resistance, compensating for the weaker left and right structural features of the vehicle 1000, strengthening the crush resistance on both sides and improving the safety of the vehicle 1000.

[0147] At this time, a sub-beam 13a is provided on each first wall segment n1, which can strengthen the structural strength of each first wall segment n1 and improve the anti-extrusion ability of each first wall segment n1, that is, the left and right anti-extrusion ability of the vehicle 1000 is improved. It can be understood that since each sub-beam 13a extends along the first direction F1, it can also improve the bending resistance of the vehicle 1000 in the front and rear directions.

[0148] In some embodiments, continue to refer to Figure 6The circumferential side wall n also 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 also include two second sub-beams 13a2, and the two second sub-beams 13a2 are respectively arranged on the two second wall segments n2, and both extend along the first direction F1.

[0149] In practical applications, the second direction F2 may correspond to the left-right direction of the housing 10. In this case, the second wall segment n2 corresponds to the circumferential side wall n in both the front-rear and rear-rear directions of the battery 100. The second wall segment n2 extends along the second direction F2, i.e., along the left-right direction of the vehicle 1000.

[0150] The sub-beams 13a on each second wall segment n2 can have the same structure, ensuring consistent anti-extrusion capabilities on both the front and rear sides. Furthermore, the sub-beams 13a on the first wall segment n1 can simply include the upper arm beam 131 mentioned in the above embodiment, with the upper arm beam 131 positioned near the top of the main body 11. In this case, the sub-beams 13a have relatively weak anti-extrusion capabilities. This is primarily because the vehicle 1000 is typically provided with anti-extrusion structures such as bumpers in the front and rear directions. When the vehicle 1000 is subjected to front-to-rear extrusion, the anti-extrusion effect is primarily achieved through its front and rear bumpers. In this case, the sub-beams 13a on the second wall segment n2 require relatively weak anti-extrusion capabilities, so a relatively simple sub-beam 13a structure can be employed, which can reduce the cost of the battery 100 and the cost of the vehicle 1000.

[0151] At this time, a sub-beam 13a is arranged on each second wall segment n2, which can strengthen the structural strength of each second wall segment n2 and improve the anti-extrusion ability of each second wall segment n2, that is, the left and right anti-extrusion ability of the vehicle 1000 is improved. It can be understood that since each sub-beam 13a extends along the second direction F2, it can also improve the bending resistance of the vehicle 1000 in the left and right directions.

[0152] In some embodiments, continue to refer to Figure 6 The lateral beam 13 includes at least two first sub-beams 13a1 and at least two second sub-beams 13a2, both of which are arranged on the circumferential side wall n. The first sub-beams 13a1 extend along the first direction F1 and are spaced apart from each other, and the second sub-beams 13a2 extend along the second direction F2 intersecting the first direction F1 and are spaced apart from each other.

[0153] In this case, the sub-beam 13a provided on the first wall segment n1 is the first sub-beam 13a1, and the sub-beam 13a provided on the second wall segment n2 is the second sub-beam 13a2. The two first sub-beams 13a1 can enhance the box body 10's ability to resist extrusion in the left-right direction of the vehicle 1000, while the two second sub-beams 13a2 can enhance the box body 10's ability to resist extrusion in the front-back direction of the vehicle 1000. This can comprehensively improve the lateral extrusion resistance of the vehicle 1000 and enhance the safety performance of the vehicle 1000.

[0154] In some embodiments, continue to refer to Figure 6 The top of the lateral beam 13 is configured with a mounting portion 13a3.

[0155] For the introduction of the mounting portion 13a3, please refer to the above records and will not be elaborated here. At this time, the mounting portion 13a3 is set on the top of the lateral beam 13, and the box body 10 of the embodiment of the present application can be obtained by adding the lateral beam 13 on the basis of the existing box body 10 structure. In this way, the cost of transformation can be greatly reduced. At the same time, the mounting portion 13a3 is set on the lateral beam 13. Since the lateral beam 13 does not need to define the accommodating cavity s, it is not necessary to consider the influence of the mounting portion 13a3 on the sealing of the accommodating cavity s when setting the mounting portion 13a3, and the setting of the mounting portion 13a3 is more flexible. Moreover, the lateral beam 13 is located at the lateral edge of the box body 10. At this time, the mounting portion 13a3 is set on the lateral beam 13, and the operating space is larger and more convenient when the box body 10 is installed on an external device.

[0156] In some embodiments, the mounting portion 13 a 3 includes at least one mounting hole k1 disposed on the top of the lateral beam 13 .

[0157] The mounting hole k1 is provided at the top of the lateral beam 13 and also has the beneficial effect of the mounting portion 13a3 being provided at the top of the lateral beam 13, which is not described in detail here.

[0158] In some embodiments, the top surface h1 of the main body 11 and the top surface h2 of the lateral beam 13 jointly define a top surface h of the box body 10 .

[0159] The top surface h1 of the main body 11 refers to the outer surface of the main body 11 located at the top thereof and facing away from the accommodating cavity s. The top surface h2 of the lateral beam 13 refers to the outer surface of the lateral beam 13 located at the top thereof. When the lateral beam 13 includes the upper arm beam 131 and the lower arm beam 132 in the above-described embodiment, the top surface h2 of the lateral beam 13 refers to the outer surface of the upper arm beam 131 facing away from the lower arm beam 132.

[0160] When the box body 10 includes both the main body 11 and the lateral beams 13 of the above-described embodiment, the top surface h of the box body 10 can be defined by the top surface h1 of the main body 11 and the top surface h2 of the lateral beams 13. The top surface h1 of the main body 11 and the top surface h2 of the lateral beams 13 can be coplanar. In this case, the top surface h of the box body 10 has a larger contact area with the external device, which helps to improve the reliability of the connection between the box body 10 and the external device. At the same time, the top structure of the box body 10 is relatively flat and more aesthetically pleasing. Of course, the top surface h1 of the main body 11 and the top surface h2 of the lateral beams 13 can also be non-coplanar.

[0161] It is understood that when the lateral beam 13 includes at least two sub-beams 13a, the top surface of each sub-beam 13a defines a portion of the top surface h2 of the lateral beam 13, and the sub-beam 13a is provided with a mounting portion 13a3. The mounting portion 13a3 may be provided on some or all of the sub-beams 13a. When the mounting portion 13a3 is provided on some of the sub-beams 13a, to ensure uniform force on the mounting portion 13a3, the mounting portion 13a3 is provided on all symmetrically arranged sub-beams 13a. The symmetrically arranged sub-beams 13a include the two first sub-beams 13a1 in the above-described embodiment, and may also include the two second sub-beams 13a2 in the above-described embodiment.

[0162] In some embodiments, please refer to Figure 6 and Figure 10 A wiring portion 13a4 is constructed on the outer wall of the box body 10. The wiring portion 13a4 is located below the top surface h of the box body 10 and forms a wiring space for the wiring harness to pass through.

[0163] The outer wall of the box 10 is the outer surface opposite the inner surface defining the accommodating cavity s within the box 10. The wiring portion 13a4 is located below the top surface of the box 10, that is, the wiring portion 13a4 is disposed on the outer wall of the box 10 below the top surface h. The outer wall of the box 10 below the top surface h includes a bottom surface and side walls connecting the top surface h and the bottom surface.

[0164] When the box body 10 includes only the main body 11, the side wall of the box body 10 may be the circumferential side wall n of the main body 11. When the box body 10 includes the main body 11 and the lateral beams 13, the side wall of the box body 10 includes the circumferential side wall n of the main body 11 not covered by the lateral beams 13 and the surface of the lateral beams 13 facing away from the main body 11.

[0165] The wiring portion 13a4 is located outside the accommodating cavity s and provides space for wiring harnesses that connect the battery cells and electrical components. The specific form of the wiring space is not limited; it only requires an inlet for the wiring harness to enter and an outlet for the wiring harness to exit. The inlet and outlet can be the same opening. The wiring space can be a wiring hole or a wiring groove k2.

[0166] Specifically, a wiring portion 13a4 may be provided on the circumferential outer wall of the box body 10, so that the wiring harness can be routed through the side of the box body 10, which is more convenient. Specifically, a wiring portion 13a4 may be provided on the bottom surface of the box body 10, so that the wiring harness can be routed through the bottom of the box body 10.

[0167] At this time, by forming a routing portion 13a4 on the outer wall of the box body 10, the routing space formed by the routing portion 13a4 is used for routing the wiring harness, which can effectively protect the wiring harness and prevent the wiring harness from being squeezed and deformed when the vehicle 1000 is squeezed from the outside, causing unnecessary safety hazards.

[0168] In a further embodiment, referring to Figure 6 and Figure 10 The wiring portion 13a4 is arranged on the side wall of the box body 10 adjacent to its own top surface h.

[0169] The sidewall is the outer surface of the box 10 connecting its top surface h and bottom surface (the surface opposite the top surface h). The wiring portion 13a4 can be provided only on a portion of the sidewalls of the box 10, such as one or two sidewalls of the box 10 in the first direction F1, or one or two sidewalls of the box 10 in the second direction F2. Of course, the wiring portion 13a4 can also be provided on all sidewalls of the box 10.

[0170] At this time, the wiring portion 13a4 is arranged on the side wall of the box body 10. Since the lateral operating space of the box body 10 is large, it is more convenient to arrange the wiring harness.

[0171] In some embodiments, the wiring portion 13a4 is arranged on two side walls of the box body 10 that are adjacent to the top surface h and opposite to each other.

[0172] The two side walls of the box 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 wiring portions 13a4 can be arranged symmetrically relative to each other in the first direction F1 or in the second direction F2. The wiring harness can be routed simultaneously from both sides of the box 10 in the first direction F1 or from both sides of the box 10 in the second direction F2. This achieves a symmetrical wiring harness arrangement, improves the appearance of the wiring harness, and also helps balance the weight of the vehicle 1000.

[0173] Furthermore, the wiring portions 13a4 are disposed on two side walls of the housing 10 in the second direction F2, i.e., on the two side walls of the housing 10 corresponding to the left and right directions of the vehicle 1000. Since the various electric drive systems (used to provide propulsion for the vehicle 1000) on the vehicle 1000 are primarily located at the front or rear, the wiring harness primarily connects the battery 100 and the electric drive systems along the front-to-back direction of the vehicle 1000. This arrangement of the wiring portions 13a4 facilitates wiring of the wiring harness.

[0174] In one specific embodiment, refer to Figure 6 and Figure 10 The wiring portion 13a4 includes a wiring groove k2 formed on the outer wall of the box body 10 and recessed toward the accommodating cavity s.

[0175] It is understood that the wiring trough k2 is recessed toward the accommodating cavity s to form a wiring space with one side open, with the open side facing the bottom of the wiring trough k2. While the wiring trough k2 is recessed toward the accommodating cavity s, it can also have a wiring inlet and a wiring outlet. Specifically, the wiring inlet of the wiring trough k2 can be an opening at one end along the direction in which the wiring trough k2 extends, and the wiring outlet of the wiring trough k2 can be an opening at the other end along the direction in which the wiring trough k2 extends.

[0176] When the wiring groove k2 is located on the side wall of the box body 10 in the second direction F2, the wiring groove k2 can extend along the first direction F1. When the wiring groove k2 is located on the side wall of the box body 10 in the first direction F1, the wiring groove k2 can extend along the second direction F2.

[0177] At this time, since the wiring groove k2 has an open opening, the open opening is more convenient for threading the wiring harness. Moreover, the wiring groove k2 formed by the depression is configured as the wiring portion 13a4, and there is no need to add other structures to form wiring space, so the box 10 structure is simpler and the cost is lower.

[0178] Of course, in other embodiments, the wiring portion 13a4 may also be a structure with a wiring hole additionally provided on the outer wall of the box body 10, such as a wiring rod with a wiring hole.

[0179] In some embodiments, reference Figure 6 and Figure 10 The lateral beam 13 is constructed to form a wiring portion 13a4.

[0180] Specifically, when the wiring portion 13a4 is a wiring groove k2, the lateral beam 13 can be composed of the upper arm beam 131 and the lower arm beam 132 in the above embodiment, and the space between the upper arm beam 131 and the lower arm beam 132 is the space where the wiring groove k2 is located. Alternatively, the outer surface of the lateral beam 13 facing away from the main body 11 is recessed to form the wiring groove k2.

[0181] When the wiring portion 13a4 is a wiring hole, the hollow beams provided at both ends of the lateral beam 13 along its extension direction can form the wiring hole within the internal space of the lateral beam 13. Alternatively, the lateral beam 13 includes the upper arm beam 131, lower arm beam 132, and middle beam (not shown) in the above embodiment, with the middle beam, upper arm beam 131, and lower wall beam collectively enclosing the wiring hole.

[0182] At this time, the routing portion 13a4 forms the lateral beam 13, that is, the lateral beam 13 has a routing space. The routing space can reduce the weight of the lateral beam 13 and realize routing, killing two birds with one stone.

[0183] In one embodiment, the upper arm beam 131 and the lower arm beam 132 are combined to form a wiring portion 13a4 having a wiring space. In this case, the wiring space is formed by the space between the upper arm beam 131 and the lower arm beam 132. The structure of the wiring portion 13a4 is simple and achieves two goals at once.

[0184] Figure 11 is a schematic diagram of a partial structure of a battery 100 in some other embodiments of the present application, Figure 12 for Figure 11 An exploded view of the side view of the structure shown, Figure 13 for Figure 11 A side view of the structure, Figure 14 for Figure 12 A magnified view of point D of the structure is shown. Figure 15 for Figure 11 Schematic diagram of application scenarios of the structure shown, Figure 16 for Figure 14 Side view of the structure shown.

[0185] In some embodiments, please refer to Figure 11 The box body 10 further includes a sealing member 12 , which is disposed on the top of the box body 10 and is used for sealingly connecting with an external device.

[0186] The seal 12 refers to a component that can prevent fluids or solid particles from leaking from adjacent joint surfaces. The seal 12 is arranged on the top of the box body 10 and divides the top of the box body 10 into an external area located outside the seal 12 and an internal area enclosed by the seal 12. The seal 12 seals and connects the two surfaces opposite to the top of the box body 10 and the external device, and forms a contact interface with the two surfaces, which can prevent fluids or solid particles in the external area outside the seal 12 from entering the internal area enclosed by the seal 12 through the contact interface between itself and the two surfaces, thereby achieving a sealing effect.

[0187] The seal 12 may be a sealing ring or a sealing gasket. Specifically, the seal 12 may be made of materials such as rubber or silicone. Specifically, the seal 12 may be an O-ring seal, a square seal, or a special-shaped seal. The specific shape of the seal 12 may be adapted to the shapes of the top of the housing 10 and the two opposing surfaces of the external device. For example, if the top of the housing 10 and the two opposing surfaces of the external device are square, the seal 12 may be a square seal.

[0188] At this time, the box body 10 of the battery 100 is sealed and connected to the external device through the sealing member 12, which is reliable and low in cost.

[0189] It can be understood that the box body 10 of the battery 100 is sealed with the external device through the sealing member 12, and is also fixedly connected to the external device through the mounting portion 13a3, and at this time the top surface h of the box body 10 is in contact with the external device.

[0190] Taking the body 200 of the vehicle 1000 as an example, the battery 100 can be installed at the bottom of the body 200 and sealed with the body 200 through the seal 12 on the sealing area hc. At this time, the internal area of ​​the seal 12 is the interior of the body 200, and the external area is the outside of the body 200. Fluids or solid particles outside the body 200 cannot leak into the interior of the body 200. For example, stones or liquids splashed during the driving of the vehicle 1000 cannot hit the interior of the body 200, thereby achieving the sealing and structural reliability of the interior of the body 200.

[0191] In some embodiments, please refer to Figure 7 and Figure 11 The top of the box body 10 is provided with a mounting position 141b on the side facing away from the receiving chamber s. The battery 100 is mounted on an external device via the top of the box body 10 and the mounting position 141b forms part of the structure of the external device.

[0192] Mounting location 141b is a localized area on the top of the housing 10 for mounting a structure (hereinafter referred to as a mounting member). This mounting member can be part of an external device, and mounting location 141b can be a connecting structure such as a mounting clip or a mounting hole. For example, if the external device is the body 200 of the vehicle 1000, mounting location 141b can be used to mount a seat 300 or an operating lever. The seat 300 or operating lever is fixedly connected to mounting location 141b on the top of the housing 10 via a mounting clip or a mounting hole.

[0193] Specifically, the mounting piece installed on the mounting position 141b can be a partial structure of the external device. The mounting position 141b for mounting the partial structure of the external device, after being connected to the external device at the top of the box 10, also forms a partial structure of the external device. At this time, the battery 100 is mounted on the external device through the top of the box 10, and after the mounting position 141b on the top of the battery 100 forms a partial structure of the external device, the connection with the external device is achieved by connecting the mounting piece to the box 10 of the battery 100.

[0194] In this way, the battery 100 and part of the external device are integrated, so that part of the structure of the battery case 100 is also part of the external device, thereby avoiding the need for the battery 100 and the external device to be separately arranged.

[0195] In other embodiments, the mounting member installed on the mounting position 141b may also be a structure other than an external device, which is installed on the mounting position 141b to achieve a fixed connection with the battery 100 and the external device at the same time.

[0196] In a specific embodiment, Figure 14 and Figure 15 Taking the vehicle body 200 of the vehicle 1000 as an external device and the installation position 141b for installing the seat 300 as an example, by constructing the installation position 141b on the top of the box 10 of the battery 100, the installation position 141b forms the internal structure of the vehicle body 200, forming an integrated setting of the battery 100 and the vehicle body 200, thereby avoiding the separation of the battery 100 and the vehicle body 200, and making the vehicle 1000 simple in structure, smaller in size and more compact.

[0197] It can be understood that the fixed connection between the box 10, the vehicle body 200 and the seat 300 can ensure that all structures are connected vertically to the top of the box 10, reducing the installation space and installation force in other directions of the box 10, reducing the force on the lateral structure and bottom structure of the battery 100 box 10, and improving the stability of the vehicle 1000 structure.

[0198] In some embodiments, please refer to Figure 7 The mounting position 141b includes a mounting hole constructed on the top of the box body 10.

[0199] The mounting hole is a through hole that vertically extends through mounting position 141b. Fasteners are required to mount seat 300, etc., to mounting position 141b. The mounting hole can be a smooth through hole (e.g., when the fastener is a rivet), a threaded through hole (e.g., when the fastener is a screw), or another through hole (e.g., a hexagonal hole, a square hole, a waist-shaped hole, etc.). The specific form of fixing hole 11c3 depends on the specific form of the fastener and the specific setting method, and is not detailed here.

[0200] The number of mounting holes is the same as the number of fasteners. A fastener is provided in each mounting hole. The corresponding mounting part is installed and positioned in the mounting hole through the fastener, so that the mounting part is fixed to the box body 10 of the battery 100 and a fixed connection between the mounting part and the external device can be achieved.

[0201] In other embodiments, the mounting position 141b may also include other structures connected to the top of the box body 10, such as a buckle, an elastic lock, etc., which are not specifically limited.

[0202] In some embodiments, please refer to Figures 4 to 7 ,and Figure 11 The box 10 includes a main body 11 and a mounting beam 141. The main body 11 encloses a receiving cavity s, and the top of the main body forms at least a portion of the top of the box 10. The mounting beam 141 is provided on the top of the main body 11 and has a mounting position 141b configured on a side thereof facing away from the main body 11.

[0203] The main body 11 can be an integrally formed structure or can be formed by assembling a plurality of parts. The specific configuration has been explained in detail above and will not be repeated here.

[0204] The top of the box body 10 has a top surface h on the side away from the accommodating cavity s. The mounting position 141b is connected to the top surface h. The mounting beam 141 is a structure with a certain load-bearing capacity provided on the top side of the main body 11, and is used to share the force exerted on the top of the box body 10 by the mounting parts. Figure 15 and 16 As shown, when the mounting member is a seat 300 , the operator will apply pressure when sitting on the seat 300 , and the pressure will first be applied to the mounting beam 141 and then to the top of the box 10 .

[0205] The mounting beam 141 can be directly set on the surface of the top surface h or on a concave or convex part formed on the top surface h. The one or more load-bearing structures included in the mounting beam 141 are jointly constructed on the side away from the top surface h to form a mounting position 141b for fixing the mounting part, thereby realizing the connection between the mounting part and the top of the box body 10.

[0206] The setting form and extension direction of the load-bearing structure are set according to the size, weight and specific structure of the mounting part installed on the mounting position 141b as required, and are not specifically limited. The mounting beam 141 is used to share the force acting on the top of the main body 11 to improve the load-bearing capacity of the box 10 of the battery 100.

[0207] In some embodiments, the mounting beam 141 is fixedly connected to the main body 11 or is integrally formed therewith.

[0208] The mounting beam 141 and the main body 11 can be fixedly connected by fastening, snap-fitting, welding, bonding, hot-melt connection, etc. Of course, the mounting beam 141 and the main body 11 can be integrally formed by injection molding, die casting, forging, cold pressing, hot pressing, etc.

[0209] When the main body 11 is made of metal (such as aluminum, iron, stainless steel, etc.), the mounting beam 141 and the main body 11 can be integrally formed by die casting, forging, hot pressing, cold pressing, etc. When the main body 11 is made of plastic (such as PP, PE, ABS, etc.), the mounting beam 141 and the main body 11 can be integrally formed by injection molding. The mounting beam 141 and the main body 11 can also be formed separately and then connected together. When 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. When 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.

[0210] When the mounting beam 141 is fixedly connected to the main body 11 , the molding process of the mounting beam 141 and the main body 11 is easier, which can reduce the manufacturing cost of the box body 10 .

[0211] When the mounting beam 141 is integrally formed with the main body 11 , the box body 10 , the external device and the mounting member can be easily assembled.

[0212] In other embodiments, the main body 11 is connected to a portion other than the mounting beam 141 , and the connection method may be either integrally formed or fixedly connected, without limitation.

[0213] In some embodiments, please refer to Figure 7 and Figure 11 The mounting beam 141 includes at least one protrusion 141a, each protrusion 141a is protruding from the top of the main body 11 in a direction away from the accommodating cavity s, and each protrusion 141a and the main body 11 together form a weight reduction channel 141a1; the mounting position 141b is constructed on the side of the protrusion 141a facing away from the main body 11.

[0214] The protrusion 141a is the load-bearing structure included in the mounting beam 141 described above. It projects from the plane of the top surface h of the box body 10, away from the accommodating cavity s. The protrusion 141a itself has a certain height, so that it protrudes from the top surface h of the box body 10. The mounting position 141b is formed on the side of all protrusions 141a facing away from the main body 11. When the mounting member is installed in the mounting position 141b, it directly contacts the protrusion 141a structure, rather than the top surface h. This disperses the force on the top of the box body 10 through the protrusion 141a, thereby increasing the load-bearing capacity of the top of the box body 10.

[0215] Each protrusion 141a can be formed into a multi-faceted structure with one end open. The top surface h1 of the main body 11 covers the open opening of each protrusion 141a and together with it form a weight-reducing channel 141a1. The weight-reducing channel 141a1 can be formed by hollowing the protrusion 141a or punching holes or grooves inside, thereby achieving a lightweight design of the box body 10.

[0216] In one embodiment, each protrusion 141a has a weight-reducing channel 141a1 extending along its interior. This reduces the weight of each protrusion 141a, thereby lowering the overall weight and cost of the housing 10. Each weight-reducing channel 141a1 can form a hidden channel. In other embodiments, this hidden channel can also be used for concealed wiring and other operations.

[0217] In some embodiments, please refer to Figures 6 to 7 , all the protrusions 141a extend in the same direction and are spaced apart from each other.

[0218] The direction referred to by “the same direction” may specifically be the first direction F1 or the second direction F2 mentioned above, or a direction coplanar with and intersecting the first direction F1 and the second direction F2 , and is not specifically limited.

[0219] The spacing of all protrusions 141a means that a predetermined spacing is maintained between adjacent protrusions 141a in a direction intersecting the direction in which the protrusions 141a extend. This spacing creates a buffer space between adjacent protrusions 141a, preventing external forces acting on the mounting beams 141 from being transferred to the housing 10 and potentially damaging the battery 100. Furthermore, the multiple, spaced protrusions 141a create a sufficiently large support area and securing points, providing wide support for mounting components and accommodating mounting components of varying sizes and volumes.

[0220] All the protrusions 141 a are arranged in parallel along the same direction, so that the buffer space and the protrusions 141 a extend in the same direction. In practical applications, buffering can be achieved at any position along the extension direction of the mounting beam 141 .

[0221] The set spacing distance between each two adjacent protrusions 141a can be equal or unequal. It can be understood that in order to ensure uniform support for the mounting member, the set spacing distance between each two adjacent protrusions 141a is equal.

[0222] In some embodiments, the sides of all the protrusions 141 a facing away from the main body 11 are located on the same plane.

[0223] All the protrusions 141a are arranged to protrude in the same direction, and the protrusion heights of all the protrusions 141a are the same, so that the side of all the protrusions 141a facing away from the installation cavity forms a flat plane in a certain direction, such as a flat plane on a horizontal plane. The installation part is placed on the flat plane for installation, which makes the installation smoother and simpler, and can achieve a firm connection between the installation part and the installation beam 141.

[0224] In a specific embodiment, the protrusion 141 a may be a quadrangular prism structure, and the same side surfaces of all the protrusions 141 a are located in the same plane and jointly define a mounting position 141 b for mounting the mounting member, so that the mounting member can be stably placed on the mounting beam 141 .

[0225] In some embodiments, please refer to Figure 4 、 Figure 7 and Figure 11 The box body 10 further includes a side impact reinforcement beam 14 , which is disposed at the top of the main body 11 and extends from the middle of the top of the main body 11 to the outer edges of the opposite sides of the top of the main body 11 .

[0226] The side impact reinforcement beam 14 is a beam structure disposed on top of the main body 11 to reinforce the main body 11. It is understood that the side impact reinforcement beam 14 is located outside the main body 11. Specifically, the main body 11 and the side impact reinforcement beam 14 are integrally connected to form a whole, or they can be connected by assembly. Integral connection includes, but is not limited to, welding, integral molding, welding, etc. Assembly connection includes, but is not limited to, snap-on connection, threaded connection, etc.

[0227] The side impact reinforcement beam 14 can extend from the middle of the top of the main body 11 to the outer edges of the top of the main body 11 on both sides in the first direction F1. In this case, the side impact reinforcement beam 14 can enhance the side impact resistance of the box body 10 in the first direction F1. The side impact reinforcement beam 14 can also extend from the middle of the top of the main body 11 to the outer edges of the top of the main body 11 on both sides in the second direction F2. In this case, the side impact reinforcement beam 14 can enhance the side impact resistance of the box body 10 in the second direction F2.

[0228] The side impact reinforcement beam 14 can extend from the middle of the top of the main body 11 in two collinear directions toward the opposite outer edges of the top of the main body 11, or can extend from the middle of the top of the main body 11 in two intersecting directions toward the opposite outer edges of the top of the main body 11. When the side impact reinforcement beam 14 extends from the middle of the top of the main body 11 toward the opposite outer edges in two collinear directions, the side impact reinforcement beam 14 is implemented as a straight beam, which simplifies the structure.

[0229] The side impact reinforcement beam 14 can extend to the outer edges on both sides, or to the area between the outer edges and the middle of both sides, or to the area outside the outer edges on both sides. In other words, the specific extension length of the side impact reinforcement beam 14 is not limited, as long as it has a state of extending from the middle of the top of the main body 11 toward the outer edges on both sides of the top of the main body 11.

[0230] When the battery 100 is applied to the vehicle 1000 and the top of the box 10 is constructed as the chassis of the vehicle 1000, since the vehicle 1000 has poor side collision prevention capability in the left and right directions, the side collision reinforcement beam 14 can be designed to extend from the middle 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, so as to enhance the side collision prevention capability of the vehicle 1000 in the left and right directions and improve the safety performance of the vehicle 1000.

[0231] At this time, a side impact reinforcement beam 14 is provided on the top of the main body 11 of the box body 10, which can improve the side impact resistance of the box body 10, and further improve the side impact resistance of the vehicle 1000 loaded with the battery 100 composed of the box body 10, which helps to ensure the safety performance of the battery 100 and the vehicle 1000.

[0232] When the main body 11 includes the frame 11b and the carrier 11a, the side impact reinforcement beam 14 is disposed at least on the top of the carrier 11a. In this case, since the top of the carrier 11a forms at least a portion of the top of the main body 11, the carrier 11a has sufficient space for the side impact reinforcement beam 14 to be installed.

[0233] In some embodiments, the side impact reinforcement beam 14 extends to connect with the top of the frame 11b.

[0234] At this time, the top of the frame 11b also forms a part of the top of the main body 11, and the side impact reinforcement beam 14 can also extend to connect with the top of the frame 11b. In addition to the direct connection between the frame 11b and the carrier 11a, the connection can also be strengthened by the side impact reinforcement beam 14, thereby enhancing the connection reliability between the frame 11b and the carrier 11a.

[0235] In some embodiments, the number of the side impact reinforcement beam 14 is at least one, and all the side impact reinforcement beams 14 extend in the same direction and are spaced apart from each other.

[0236] The direction referred to by “the same direction” may specifically be the first direction F1 or the second direction F2 mentioned above, or a direction coplanar with and intersecting the first direction F1 and the second direction F2 , and is not specifically limited.

[0237] All side impact reinforcement beams 14 extend in the same direction, and each side impact reinforcement beam 14 can strengthen the side impact resistance of the box body 10 in the direction of extension, thereby enhancing the side impact resistance of the box body 10 in this direction of extension. It can be understood that the side impact reinforcement beams 14 are arranged at intervals along a direction intersecting the "same direction", thereby strengthening the strength of the box body 10 at multiple locations, making the structural strength and side impact resistance of the box body 10 more uniform.

[0238] In some embodiments, at least one of the side impact reinforcement beams 14 is configured as a mounting beam 141 , and a mounting position 141 b is configured on a side of the mounting beam 141 facing away from the main body 11 .

[0239] The introduction to the mounting beam 141 and the mounting position 141b is detailed above and will not be repeated here. When the side impact reinforcement beam 14 includes one, the side impact reinforcement beam 14 is used as the mounting beam 141. When the side impact reinforcement beam 14 includes at least two, a portion of the side impact reinforcement beam 141 can be used. Specifically, when the side impact reinforcement beam 14 includes at least two, the side impact reinforcement beam 14 near the front of the vehicle 1000 can be used as the mounting beam 141 for installing the seat 300 (the seat 300 can be the seat 300 in the cab).

[0240] At this time, using at least one of the side impact reinforcement beams 14 as the mounting beam 141 not only has the effect of preventing side impact, but also can be used to install other mounting parts, thus serving two purposes.

[0241] In some embodiments, the side impact reinforcement beam 14 includes at least one protrusion 141a, each protrusion 141a is protruding from the top of the main body 11 in a direction away from the accommodating cavity s, and each protrusion 141a and the main body 11 together form a weight reduction channel 141a1.

[0242] The protrusion 141a of the side impact reinforcement beam 14 is identical in structure to the protrusion 141a described above when describing the structure of the mounting beam 141. For further details, please refer to the above description. The protrusion 141a projects from the plane of the top surface h1 of the main body 11, away from the accommodating cavity s. The protrusion 141a itself has a certain height, thereby protruding from the top surface h1 of the main body 11.

[0243] Each protrusion 141a can be formed into a multi-faceted structure with one end open. The top surface h1 of the main body 11 covers the open opening of each protrusion 141a and together with it form a weight-reducing channel 141a1. The weight-reducing channel 141a1 can be formed by hollowing the protrusion 141a or punching holes or grooves inside, thereby achieving a lightweight design of the box body 10.

[0244] In one embodiment, each protrusion 141a has a weight-reducing channel 141a1 extending along its interior. This reduces the weight of each protrusion 141a, thereby lowering the overall weight and cost of the housing 10. Each weight-reducing channel 141a1 can form a hidden channel. In other embodiments, this hidden channel can also be used for concealed wiring and other operations.

[0245] In some embodiments, please refer to Figure 7 , all the protrusions 141a extend in the same direction and are spaced apart from each other.

[0246] The spacing of all protrusions 141a means that a predetermined spacing is maintained between adjacent protrusions 141a in a direction intersecting the direction in which the protrusions 141a extend. This spacing creates a buffer space between adjacent protrusions 141a, preventing external forces acting on the mounting beams 141 from being transferred to the housing 10 and potentially damaging the battery 100. Furthermore, the multiple, spaced protrusions 141a create a sufficiently large support area and securing points, providing wide support for mounting components and accommodating mounting components of varying sizes and volumes.

[0247] All the protrusions 141 a are arranged in parallel along the same direction, so that the buffer space and the protrusions 141 a extend in the same direction. In actual application, buffering can be achieved at any position in the extension direction of the side impact reinforcement beam 14 .

[0248] The set spacing distance between each two adjacent protrusions 141a can be equal or unequal. It can be understood that when the side impact reinforcement beam 14 is used as the installation beam 141, in order to ensure uniform support for the installation parts, the set spacing distance between each two adjacent protrusions 141a is equal.

[0249] In some embodiments, the sides of all the protrusions 141 a facing away from the main body 11 are located on the same plane.

[0250] One side of all the protrusions 141a is located on the top surface h1 of the main body 11, and all the protrusions are arranged to protrude in the same direction and have the same height, so that the side of all the protrusions 141a facing away from the mounting cavity forms a flat plane in a certain direction, such as a flat plane on a horizontal plane, to achieve a firm connection between the mounting piece and the mounting beam 141.

[0251] In a specific embodiment, the protrusion 141 a may be a quadrangular prism structure, and the same side surfaces of all the protrusions 141 a are located in the same plane and jointly define a mounting position 141 b for mounting the mounting member, so that the mounting member can be stably placed on the mounting beam 141 .

[0252] In some embodiments, please refer to Figure 10 The box body 10 is formed with a battery chamber s1 and a high-voltage chamber s2 that are independently provided. The battery chamber s1 is used to accommodate the battery cell 20, and the high-voltage chamber s2 is used to accommodate the high-voltage box.

[0253] The high-voltage box is an important safety barrier for the battery group 100. It is equipped with a high-voltage control system and is mainly used to: connect or disconnect the high-voltage circuit according to the vehicle's electronic control requirements; provide current and leakage detection terminals; achieve controllable load cut-off when the external current of the battery group 100 is too large; when a short circuit occurs in the external circuit of the battery group 100, the high-voltage circuit is disconnected to prevent the battery group 100 from catching fire; when repairing the battery group 100, the high-voltage circuit can be easily cut off.

[0254] The battery chamber s1 and the high-pressure chamber s2 are independently arranged from each other, which means that the battery chamber s1 and the high-pressure chamber s2 are sealed from each other. In order to achieve the independent arrangement of the battery chamber s1 and the high-pressure chamber s2, the battery chamber s1 and the high-pressure chamber s2 may be formed by two independent components, for example, an independent first component and a second component are arranged inside the box body 10, the first component forms the battery chamber s1, and the second component forms the high-pressure chamber s2. Alternatively, a partition is arranged inside the box body 10 to separate the accommodating chamber s formed inside the box body 10 into independent battery chambers s1 and high-pressure chambers s2. Alternatively, all the accommodating chambers s formed inside the box body 10 are used as battery chambers s1, and a high-pressure chamber 15 is constructed outside the box body 10 to form the high-pressure chamber s2, so as to achieve the independence of the battery chamber s1 and the high-pressure chamber s2.

[0255] The battery cavity s1 is used to accommodate the battery cell 20, and the high-voltage cavity s2 is used to accommodate the high-voltage box. When the battery cavity s1 and the high-voltage cavity s2 are set independently, if the high-temperature gas leaked by the battery cell 20 in the battery cavity s1 due to thermal failure will not enter the high-voltage box, and will not cause thermal damage to the high-voltage control system in the high-voltage box, which can ensure the normal control function of the high-voltage control system and improve the safety performance of the battery 100.

[0256] In some embodiments, reference Figures 11 to 13 The box body 10 also includes a high-voltage chamber 15, a battery chamber s1 is formed in the main body 11, and the high-voltage chamber 15 is arranged outside the main body 11, and is enclosed by itself or together with the main body 11 to form a high-voltage chamber s2.

[0257] The high-voltage chamber 15 can be a housing 22 structure, with a hollow interior forming the high-voltage chamber 15 for housing the high-voltage box. The high-voltage chamber 15 is disposed outside the main body 11, and the battery chamber s1 is formed by the main body 11 (in this case, the battery chamber s1 is equivalent to the storage chamber s), thus achieving the independent arrangement of the high-voltage chamber s2 and the battery chamber s1.

[0258] When the high-pressure chamber 15 and the main body 11 together form the high-pressure chamber s2, the high-pressure chamber 15 has an opening and is mounted on the main body 11 through the opening. When the high-pressure chamber 15 itself encloses the high-pressure chamber s2, it only has a mounting relationship with the main body 11.

[0259] At this time, the high-pressure chamber 15 provided outside the main body 11 defines a high-pressure chamber s2 , and the accommodating chamber s formed by the main body 11 can be used as a battery chamber s1 to accommodate the battery cell 20 , thereby increasing the capacity of the battery 100 .

[0260] In some embodiments, reference is made to Figures 11 to 12 The high-pressure chamber 15 is protrudingly arranged on the top of the main body 11.

[0261] The high-voltage chamber 15 protrudes from the top of the main body 11, that is, it is located outside the main body 11 and is located on the top surface h1 of the main body 11. When the battery 100 housing 10 is used as the chassis of the vehicle 1000, the high-voltage chamber 15 is located on the top of the main body 11 and is not exposed to the outside of the vehicle 1000. It can be protected from external impacts (such as stones flying during the vehicle 1000), and the high-voltage chamber 15 is safer.

[0262] It is understood that when the main body 11 includes the aforementioned frame 11b and the aforementioned support member 11a, the support member 11a constitutes at least a portion of the top of the main body 11. The high-pressure chamber 15 is disposed on top of the support member 11a and encloses the high-pressure chamber s2, either by itself or in conjunction with the support member 11a. In this case, since the support member 11a constitutes the majority of the top area of ​​the main body 11, locating the high-pressure chamber 15 on top of the support member 11a provides more space for its installation, making the installation more stable.

[0263] Of course, when the top of the frame 11b is also constructed as a part of the top of the main body 11, the high-pressure chamber 15 can also be set on the top of the frame 11b, which can be specifically set according to the installation method of the frame 11b and the carrier 11a.

[0264] In some embodiments, reference is made to Figures 11 to 13 The high-pressure chamber 15 is arranged near the top outer edge of the main body 11.

[0265] The top outer edge of the main body 11 includes: one side outer edge of the top of the main body 11 is set in the front direction of the vehicle 1000, one side outer edge of the top of the main body 11 is set in the rear direction of the vehicle 1000, one side outer edge of the top of the main body 11 is set in the left direction of the vehicle 1000, and one side outer edge of the top of the main body 11 is set in the right direction of the vehicle 1000.

[0266] In one application example, the high-pressure chamber 15 is arranged near the top of the main body 11 on the outer edge of one side in the rear direction of the vehicle 1000, that is, the high-pressure chamber 15 is arranged near the rear of the vehicle 1000. At this time, the high-pressure chamber 15 can be arranged corresponding to the passenger space behind the driving space of the vehicle 1000, in particular, it can be arranged corresponding to the bottom of the seat 300 in the passenger space, and does not need to occupy the activity space of the vehicle 1000.

[0267] In some embodiments, reference Figure 4 、 Figure 6 、 Figures 11 to 13 The high-pressure compartment 15 and the side impact reinforcement beam 14 are arranged sequentially in a first direction F1, and the side impact reinforcement beam 14 extends along a second direction F2 intersecting the first direction F1.

[0268] When the box body 10 includes the side impact reinforcement beam 14 , the high-pressure chamber 15 and the side impact reinforcement beam 14 can both be disposed on the top of the main body 11 .

[0269] The high-pressure chamber 15 and the side impact reinforcement beams 14 are arranged sequentially in the first direction F1, meaning that the high-pressure chamber 15 is located on one side of all the side impact reinforcement beams 14 in the first direction F1. Furthermore, the side impact reinforcement beams 14 extend in a second direction F2 that intersects the first direction F1, without interfering with the high-pressure chamber 15. This structural arrangement of the high-pressure chamber 15 and the side impact reinforcement beams 14 is relatively rational, and the space above the main body 11 is highly utilized.

[0270] In relation to the specific embodiments, refer to Figure 4 The high-pressure chamber 15 includes a chamber cover 15a and a chamber box 15b. The chamber box 15b is arranged on the top of the main body 11 and forms a high-pressure chamber s2 open away from the main body 11. The chamber cover 15a is detachably covered on the open side of the high-pressure chamber s2.

[0271] The connection between the box 15b and the main body 11 can be welded, fused, bonded, or fastened. The box 15b can also be made of plastic. The cover 15a and the box 15b can be removably connected by fasteners or by snap-fitting, and the specific method is not limited.

[0272] At this time, the high-pressure chamber s2 is formed by the magazine box 15b, and the high-pressure chamber s2 is sealed by the magazine cover 15a. The magazine cover 15a and the magazine box 15b are detachably connected, which is convenient for installation and maintenance of the high-pressure box.

[0273] Figure 17 is a schematic diagram of a partial structure of a battery 100 in some other embodiments of the present application, Figure 18 for Figure 17 A side view of the structure shown, Figure 19 for Figure 18 An exploded view of the structure, Figure 20 for Figure 18A cross-sectional view of the structure shown at EE. Figure 21 for Figure 17 A top view of the structure shown.

[0274] In some embodiments, please refer to Figures 17 to 21 The box body 10 also includes a middle channel beam 16, which extends along the first direction F1 and is arranged on the top of the main body 11, and is equidistant from the outer edges on both sides of the top of the main body 11 in a second direction F2 intersecting with the first direction F1. The middle channel beam 16 has a wiring channel 16a for the wiring harness to pass through.

[0275] In a conventional vehicle 1000, a center channel beam 16 is typically installed on the chassis of the vehicle 1000's body 200. This beam extends from the front to the rear chassis of the vehicle 1000. It serves as a primary structural member for the collision transmission path of the vehicle 200 and ensures the floor rigidity of the vehicle 200. The center channel beam 16 is located in the middle of the chassis of the vehicle 1000 and extends from the front to the rear chassis along the front-to-rear direction of the vehicle 1000.

[0276] In this embodiment, the central channel beam 16 of the vehicle 1000 is directly integrated into the top of the main body 11 of the box body 10. Specifically, the central channel beam 16 extends along a first direction F1 (corresponding to the front-to-back direction of the vehicle body 200) and is equidistant from both outer edges of the top of the main body 11 in a second direction F2 (corresponding to the left-to-right direction of the vehicle body 200), thereby being arranged in the central region of the top of the main body 11.

[0277] Typically, to reduce the weight of the vehicle body 200 and achieve lightweighting, the central channel beam 16 is designed as a hollow structure. In this embodiment, the hollow structure within the central channel beam 16 is utilized to form a wiring channel 16a for the wiring harness to pass through. This not only reduces weight but also enables more flexible and safe wiring harness layout.

[0278] The middle channel beam 16 can be a sheet metal component integrally formed by stamping, die-casting, etc., or it can be a beam structure formed by welding, welding or fastening multiple sheet metal plates, as long as it can form a wiring channel 16a for wiring. The wiring channel 16a can be located inside the middle channel beam 16 (such as a hole inside the middle channel beam 16), or it can be located outside the middle channel beam 16 (such as a groove channel recessed outside the middle channel beam 16). The middle channel beam 16 can form the wiring channel 16a together with the main body 11, or it can enclose itself to form the wiring channel 16a. The middle channel beam 16 and the main body 11 can be connected to form a whole by welding, welding, fastening, etc.

[0279] The wiring channel 16a of the central channel beam 16 can extend along the extension direction of the central channel beam 16 (i.e., the first direction F1), or can be designed in other ways as needed, without limitation, as long as wiring can be achieved. The central channel beam 16 can be provided with multiple independent wiring channels 16a to achieve classified routing of different types of wiring harnesses, facilitating installation and maintenance.

[0280] In this case, when the top of the box 10 serves as the chassis of the vehicle 1000 body 200 (the chassis is the floor of the vehicle body 200), there is no need for an additional central channel beam 16, which improves the assembly efficiency of the vehicle body 200. Furthermore, the hollow structure formed within the central channel beam 16 forms a wiring channel 16a for the wiring harness to pass through, which not only reduces weight but also enables more flexible wiring harness layout.

[0281] In some embodiments, please refer to Figure 20 The middle channel beam 16 includes a beam seat 161, which is arranged on the top of the main body 11 and forms a wire groove 16a1 as a wiring channel 16a, and the wire groove 16a1 is recessed toward the accommodating cavity s.

[0282] The beam base 161 is directly mounted on the main body 11 and can be fixed to the main body 11 by welding, fusion, fastening, etc. The beam base 161 is formed with a wire groove 16a1, which is recessed toward the accommodating cavity s. In other words, the wire groove 16a1 has a notch facing away from the accommodating cavity s, through which the wire harness can be easily passed.

[0283] The wire passing groove 16a1 can be a continuous groove structure formed by being recessed on the surface of the side of the beam seat 161 facing away from the accommodating cavity s, or it can be a plurality of wire passing portions with grooves recessed toward the accommodating cavity constructed on the surface of the side of the beam seat 161 facing away from the accommodating cavity s, each wire passing portion is arranged at intervals along a set direction, and the grooves of all the wire passing portions together form the wire passing groove 16a1 of the beam seat 161.

[0284] At this time, the beam seat 161 forms a wire groove 16a1 that is recessed toward the accommodating cavity s, making it easier to install the wire harness.

[0285] In some embodiments, please refer to Figure 20 There are multiple wire-passing grooves 16a1, and all of the wire-passing grooves 16a1 extend in the same direction and are spaced apart from each other.

[0286] Multiple wire ducts 16a1 are provided, and the multiple wire ducts 16a1 can extend in the same direction (e.g., the first direction F1) and be spaced apart. Each wire duct 16a1 can be used to route a type of wiring harness (the wiring harnesses can be categorized based on the objects they connect to, such as a wiring harness connected to the air conditioner, a wiring harness connected to the headlights, a wiring harness connected to the power drive system, etc.).

[0287] In this way, different types of wiring harnesses can be arranged independently, making wiring harness installation and maintenance more convenient.

[0288] In some embodiments, the wire channel 16a1 is configured to engage with a wire harness passing through the channel.

[0289] In order to achieve the clamping of the wiring harness in the wire duct 16a1, the size of the notch of the wire duct 16a1 can be comparable to the diameter of the wire harness passing through it, or the two can be interference-fitted to achieve the clamping connection. Alternatively, a clamping piece can be designed in the notch of the wire duct 16a1, with one end of the clamping piece rotatably connected to one side of the notch of the wire duct 16a1 and the other end detachably clamped to the other side of the notch of the wire duct 16a1. When the wire harness is arranged in the wire duct 16a1, the clamping piece is clamped to the notch of the wire duct 16a1 to clamp the wire harness in the wire duct 16a1.

[0290] In this way, the noise caused by the shaking of the wire harness can be avoided, and the problem of the wire harness being damaged due to the wire harness escaping from the wire groove 16a1 can also be avoided.

[0291] In some embodiments, please refer to Figure 20 The middle channel beam 16 further includes a beam cover 162, which is detachably covered on the opening side of the wire groove 16a1.

[0292] The open side of the wire duct 16a1 is the side where the notch of the wire duct 16a1 is located. The beam cover 162 is detachably covered on the open side of the wire duct 16a1, that is, the beam cover 162 is detachably connected to the beam seat 161. Specifically, the beam cover 162 and the beam seat 161 are detachably engaged, or the beam cover 162 and the beam seat 161 are detachably connected via fasteners (such as bolts). The method for achieving the detachable connection between the beam cover 162 and the beam seat 161 can adopt conventional arrangements in the art and will not be limited or elaborated herein.

[0293] At this time, the beam cover 162 covers the notch of the wire groove 16a1, which can prevent external dust and moisture from entering the wire groove 16a1 and corroding the wire harness. At the same time, it can also protect the wire harness from external force squeezing and damage, thereby improving the safety of the battery 100.

[0294] In some embodiments, the high-pressure chamber s2 is in communication with the wiring channel 16a.

[0295] It is understandable that the wiring harness is usually led out from the high-voltage box in the high-voltage chamber s2 and then supplies power to the electrical devices, so the wiring harness passes through the high-voltage chamber s2 and the wiring channel 16a.

[0296] The high-pressure chamber s2 is connected to the wiring channel 16a, which means that the wiring bundle exiting the high-pressure chamber s2 can enter the wiring channel 16a. Specifically, the high-pressure chamber s2 may have a wiring opening, which is opposite to the entrance of the wiring channel 16a. In this case, there is no obstacle between the wiring opening and the entrance of the wiring channel 16a, and the wiring bundle exiting through the wiring opening can directly enter the entrance of the wiring channel 16a without turning. Specifically, the high-pressure chamber s2 may have a wiring opening, which is not opposite to the entrance of the wiring channel 16a and is spatially connected. In this case, there is an obstacle between the wiring opening and the entrance of the wiring channel 16a (the obstacle may be formed by the middle channel beam 16 or other structures), and the wiring bundle exiting through the wiring opening needs to turn around the obstacle before entering the wiring channel 16a through the entrance of the wiring channel 16a.

[0297] At this time, the high-pressure chamber s2 is connected to the wiring channel 16a, so that the wiring harness coming out of the high-pressure chamber s2 can be arranged through the wiring channel 16a.

[0298] In some embodiments, please refer to Figure 17 and Figure 21 The middle channel beam 16 and the high-pressure chamber 15 are arranged adjacent to each other along the first direction F1.

[0299] The central channel beam 16 generally corresponds to extending from the front chassis of the vehicle body 200 to the rear chassis of the vehicle body 200. The high-pressure chamber 15 is located on one side of the central channel beam 16 in the first direction F1. The high-pressure chamber 15 can be arranged in front of or behind the central channel beam 16. Specifically, the high-pressure chamber 15 can be arranged behind the central channel beam 16. The high-pressure chamber 15 corresponds to the position of the rear chassis of the vehicle body 200. Since the position of the rear chassis of the vehicle body 200 can be used to install the seats 300 of the passenger compartment of the vehicle 1000, the high-pressure chamber 15 can be arranged by hiding it in the space below the seats 300, thereby improving the space utilization rate of the passenger compartment of the vehicle 1000.

[0300] In some embodiments, please refer to Figure 11 The top surface h of the housing 10 is formed with a first area ha and a second area hb. The second area hb surrounds the first area ha. The second area hb is configured with a plurality of mounting portions 13a3, and the battery 100 is mounted on an external device through the mounting portions 13a3.

[0301] The first area ha and the second area hb can be formed by another structural division, such as by providing a seal 12 on the top of the box body 10 and dividing the top surface h of the box body 10 into a second area hb located outside the seal 12 and a first area ha located inside the seal 12. When the battery 100 is installed on an external device through the mounting portion 13a3, the first area ha and the second area hb are independent of each other.

[0302] The first area ha and the second area hb can also be formed by automatic partitioning on the top surface h. In this case, there is no other structural separation between the first area ha and the second area hb. When the battery 100 is installed on an external device through the mounting portion 13a3, the first area ha and the second area hb can also be connected to each other.

[0303] Furthermore, the area sizes of the first region ha and the second region hb are not limited. The first region ha and the second region hb may be flat surfaces or uneven surfaces, and their specific structures are not limited.

[0304] In a specific embodiment, if the external device is the body 200 of the vehicle 1000, the mounting portion 13a3 is constructed in the second area hb, so that the box 10 is connected to the body 200 through the relatively outer area of ​​the top. At this time, the box 10 is only subjected to the vertical force of the body 200, which reduces the force transmission path and is more conducive to improving the rigidity and lateral extrusion capacity of the entire vehicle.

[0305] It can be understood that the top surface h of the box body 10 may include other areas in addition to the first area ha and the second area hb. The other areas may be arranged between the two areas, around the two areas, or inside the two areas, which is not specifically limited in this application.

[0306] In some embodiments, please refer to Figures 13 and 14 The distance L2 between the geometric centers of the orthographic projections of two adjacent mounting portions 13a3 on the second area hb is 80 mm to 500 mm.

[0307] Orthographic projection refers to the projection of parallel projection lines perpendicular to the projection plane, that is, the mounting portion 13a3 is projected onto the second area hb in a direction perpendicular to the second area hb. When the mounting portion 13a3 is connected to an external device, each mounting portion 13a3 has a mounting force point. The geometric center of the orthographic projection of each mounting portion 13a3 on the second area hb is the mounting force point. The distance between each two adjacent mounting force points (i.e., distance L2) is limited to 80-500mm to ensure that the battery 100 is evenly mounted on the external device and improve the connection strength between the battery 100 and the external device.

[0308] In one specific embodiment, when the external device is the vehicle body 200 of the vehicle 1000, the mounting portion 13a3 is provided to include a plurality of mounting holes k1, and the housing 10 of the battery 100 is connected to the vehicle body 200 via the plurality of mounting holes k1. Furthermore, the distance L2 between the geometric centers of adjacent mounting holes k1 is within a limited range to ensure that the distance between the mounting holes k1 (i.e., the distance L2) is controllable. By controlling the distance between the mounting holes k1, the multiple mounting positions on the housing 10 are substantially evenly distributed, resulting in a uniform force on the vehicle body 200, thereby improving the connection stiffness between the vehicle body 200 and the housing 10 at various locations.

[0309] It can be understood that in some other embodiments, if personalized settings need to be implemented, for example, the mounting portion 13a3 needs to be divided into a dense mounting area and a sparse mounting area, then the distance between the mounting holes k1 in the dense mounting area (i.e., the distance L2) can be set as close to the 80 mm side as possible, and the distance between the mounting holes k1 in the sparse mounting area (i.e., the distance L2) can be set as close to the 500 mm side as possible, so as to meet the personalized needs of local dense mounting and local sparse mounting.

[0310] In some embodiments, please refer to Figures 13 and 14 The distance L2 between the geometric centers of the orthographic projections of two adjacent mounting portions 13a3 on the second area hb is 80 mm to 300 mm.

[0311] The distance L2 is within the range of 80 mm to 300 mm, which can ensure uniform connection between the battery 100 and the external device while ensuring connection strength between the battery 100 and the external device.

[0312] In some embodiments, please refer to Figures 13 and 14 The top surface h of the box body 10 is also formed with a sealing area hc, which is arranged between the first area ha and the second area hb, and surrounds the first area ha. The sealing area hc is used to install a sealing member 12, and the sealing member 12 is used to contact an external device.

[0313] The sealing area hc is also a part of the top surface h of the box body 10. It is located between the first area ha and the second area hb to separate the first area ha and the second area hb to form a non-connected relationship. The area of ​​the sealing area hc should not be too large. Its main function is to install the seal 12 to achieve mutual isolation between the first area ha and the second area hb. It is set to imitate the size, volume and shape of the seal 12 as much as possible to ensure that the entire seal 12 is assembled in the sealing area hc.

[0314] It is understood that the seal 12 has different states within the sealing area hc. 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 deforms to ensure sealing. When the battery 100 is separated from the external device, the seal 12 returns to its original state.

[0315] In a specific embodiment, if the external device is the body 200 of the vehicle 1000, the battery 100 can be installed at the bottom of the body 200 and sealed with the body 200 through the seal 12 on the sealing area hc. At this time, the first area ha forms a closed interior of the body 200, and the second area hb is the outside of the body 200. Fluids or solid particles outside the body 200 cannot leak into the interior of the body 200. For example, stones or liquids splashed during the driving of the vehicle 1000 cannot hit the interior of the body 200, thereby achieving the sealing and structural reliability of the interior of the body 200.

[0316] It is understood that when the housing 10 includes a seal 12, the seal 12 is installed in the sealing area hc to seal and isolate the first area ha from the second area hb. The specific configuration of the seal 12 has been described in detail above and will not be repeated here. In addition to the first area ha, the sealing area hc, and the second area hb, the top surface h of the housing 10 may also include other areas. The other areas may be located either inside the first area ha or outside the second area hb, and this application does not specifically limit this.

[0317] In some embodiments, please refer to Figures 13 and 14 The shortest distance L1 between the geometric center of the orthographic projection of the mounting portion 13a3 on the second region hb and the outer edge of the sealing region hc is 30 mm to 200 mm.

[0318] The mounting portion 13a3 is projected onto the second area hb in a direction perpendicular to the second area hb. When the mounting portion 13a3 is connected to an external device, each mounting portion 13a3 has a mounting force point. The geometric center of the orthographic projection of each mounting portion 13a3 onto the second area hb is the mounting force point of each mounting portion 13a3. The shortest distance L1 between the geometric center of the orthographic projection of the mounting portion 13a3 onto the second area hb and the outer edge of the sealing area hc is the shortest distance between the mounting force point of each mounting portion 13a3 and the outer edge of the sealing area hc.

[0319] The outer edge of sealing area hc is the shared boundary between sealing area hc and second area hb. Naturally, sealing area hc also has an inner edge, which is the shared boundary between sealing area hc and first area ha. When sealing member 12 is assembled, the outer edges of sealing member 12 coincide with the inner and outer edges of sealing area hc, so that sealing member 12 completely covers sealing area hc.

[0320] The shortest distance L1 between the geometric center of the positive projection of the mounting portion 13a3 in the second area hb and the outer edge of the sealing area hc refers to the length of the perpendicular line drawn from the geometric center of each mounting portion 13a3 to the outer edge of the sealing area hc, so as to ensure that the distance between the seal 12 and the mounting portion 13a3 is within a limited range.

[0321] In a specific embodiment, if the external device is the body 200 of the vehicle 1000, the shortest distance (i.e., distance L1) between the mounting force point of the mounting portion 13a3 and the outer edge of the sealing area hc is controlled to be 30mm-200mm. This can prevent the mounting force point of the mounting portion 13a3 from being too far away from the seal 12. On the one hand, it ensures the sealing effect of the seal 12 on the inside of the body 200. On the other hand, it reduces the mounting torque of each mounting portion 13a3 mounted on the body 200, effectively shortens the mounting force arm, and ensures the connection stiffness between the battery 100 and the body 200.

[0322] In some embodiments, please refer to Figures 13 and 14 The shortest distance L1 between the geometric center of the orthographic projection of the mounting portion 13a3 on the second region hb and the outer edge of the sealing region hc is 50 mm to 100 mm.

[0323] Within the range of 50mm-100mm, the mounting force point of the mounting portion 13a3 can be prevented from being too far away from the seal 12, thereby ensuring the sealing and isolation effect of the seal 12 on the first area ha and the second area hb, while ensuring the connection strength between the battery 100 and the external device.

[0324] In some embodiments, the sealing region hc is coplanar with the second region hb.

[0325] Coplanar, also known as coplane, means that the sealing area hc and the second area hb occupy the same plane in three-dimensional space. At this time, the sealing area hc and the second area hb are both constructed as flat planes and no angle is formed between them.

[0326] In a specific embodiment, when the external device is the body 200 of the vehicle 1000, the box 10 is assembled on the bottom of the body 200 through the top, the sealing area hc and the second area hb have the same height in the vertical direction, the sealing area hc is used to set the seal 12 for performing the sealing function, and the second area hb is constructed with a mounting part for performing the mounting function. At this time, the mounting force point of each mounting part 13a3 is located in the same plane and at the same height as the sealing area hc, and the mounting force point and the seal 12 only bear the force in the vertical direction, thereby reducing the lateral structural force of the box 10 and the body 200 and improving the rigidity of the vehicle 1000.

[0327] In some embodiments, please refer to Figure 11 , the first area ha, the second area hb and the sealing area hc are coplanar.

[0328] At this time, the coplanar plane of the first area ha, the second area hb and the sealing area hc contacts the external device, and the contact area h of the top surface of the box 10 with the external device is larger, which helps to improve the connection reliability between the box 10 and the external device. At the same time, the top structure of the box 10 is relatively flat and more beautiful.

[0329] When the external device is the body 200 of the vehicle 1000, the internal area of ​​the body 200, the external area of ​​the body 200 and the sealing area hc on the top surface h of the box body 10 are all arranged in the same plane, ensuring that the internal area of ​​the body 200 and the external area of ​​the body 200 of the box body 10 only bear force in the vertical direction, thereby further reducing the lateral structural force of the vehicle 1000.

[0330] In some embodiments, please refer to Figure 14 , when the mounting portion 13a3 includes at least one mounting hole k1, all mounting holes k1 pass through the second area hb.

[0331] For an introduction to the mounting hole k1, please refer to the above description and will not be elaborated here. When the mounting hole k1 is set to pass through the second area hb, the connector can be connected to the top of the box body 10 from the second area hb which is relatively outer of the top of the box body 10 when connecting the box body 10 to the external device, so as to improve the connection strength between the box body 10 and the external device.

[0332] In some embodiments, please refer to Figure 14 There is a reserved distance between the outer edge of the sealing area hc close to the second area hb and the circumferential side wall n of the main body 11.

[0333] For the introduction of the n holes on the circumferential side wall of the main body 11, please refer to the above records and will not be elaborated here. The outer edge of the sealing area hc close to the second area hb is not coplanar with the plane of the circumferential side wall n of the main body 11 in the vertical direction, so that the outer edge of the sealing area hc has a certain reserved distance from the outer edge of the top surface h1 of the main body 11.

[0334] When the seal 12 is assembled and has not been deformed, the two side edges of the seal 12 coincide with the inner and outer side edges of the sealing area hc. When the seal 12 is sealed and connected to an external device, the seal 12 is deformed and its two sides overflow the sealing area hc. One side extends beyond the sealing area hc into the first area ha, and the other side extends beyond the sealing area hc into the second area hb.

[0335] A reserved distance is set between the outer edge of the sealing area hc close to the second area hb and the axial side wall of the main body 11, which can reserve sufficient deformation space for the deformation of the seal 12 and prevent the seal 12 from overflowing over the top surface h1 of the main body 11 to other areas on the top of the box body 10 and interfering with structures in other areas when deforming.

[0336] In some embodiments, please refer to Figure 11 and Figure 13 The top surface h1 of the main body 11 defines and forms at least a portion of the top surface h of the box body 10 .

[0337] The top surface h1 of the main body 11 refers to the side surface of the main body 11 located at the top thereof and facing away from the accommodating cavity s. When the box body 10 includes both the main body 11 and the lateral beam 13 in the above-mentioned embodiment, the top surface h of the box body 10 can be defined by the top surface h1 of the main body 11 and the top surface h2 of the lateral beam 13. Among them, the top surface h1 of the main body 11 and the top surface h2 of the lateral beam 13 can be coplanar. In this case, the contact area between the top surface h of the box body 10 and the external device is larger, which helps to improve the connection reliability between the box body 10 and the external device. At the same time, the top structure of the box body 10 is relatively flat and more beautiful. Of course. The top surface h1 of the main body 11 and the top surface h2 of the lateral beam 13 can also be non-coplanar.

[0338] In other embodiments, the box body 10 may also include other structures in addition to the main body 11 and the lateral beams 13. In this case, the top surface h of the box body 10 is defined by the top surface h1 of the main body 11, the top surface h2 of the lateral beams 13 and the top surfaces of other structures.

[0339] It can be understood that the first area ha and the sealing area hc are located on the top surface h1 of the main body 11. In addition to the first area ha and the sealing area hc, the top surface h1 of the main body 11 may also include other areas, which are not specifically limited here.

[0340] In some embodiments, please refer to Figure 11 and Figure 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 .

[0341] The top surface h1 of the main body 11 is divided into a first area ha, a sealing area hc outside the first area ha, and a second area hb outside the sealing area hc. When the sealing member 12 in the sealing area hc is compressed and deformed, one side edge of the sealing member 12 extends into the second area hb on the top surface h1 of the main body 11.

[0342] It can be understood that the second area hb on the top surface h1 of the main body 11 is the reserved distance between the outer edge of the sealing area hc close to the second area hb and the circumferential side wall n of the main body 11, so as to ensure that sufficient deformation space is reserved for the deformation of the seal 12, so as to avoid the seal 12 from crossing the top surface h1 of the main body 11 and overflowing onto the lateral beam 13 when deforming.

[0343] In some embodiments, the mounting portion 13 a 3 is located in a second region hb defined by the top surface h2 of the lateral beam 13 .

[0344] The mounting hole k1 is provided in the second area hb defined by the top surface h2 and also has the beneficial effect of the mounting portion 13a3 being provided on the top of the lateral beam 13.

[0345] When the box body 10 includes both the main body 11 and the lateral beams 13 of the above-described embodiment, the top surface h of the box body 10 can be defined by the top surface h1 of the main body 11 and the top surface h2 of the lateral beams 13. A reserved distance is provided between the outer edge of the sealing region hc proximate to the second region hb and the axial sidewall of the main body 11 to provide sufficient deformation space for the seal 12. This prevents the seal 12 from deforming and overflowing over the top surface h1 of the main body 11 onto the top surface h2 of the lateral beams 13, thereby interfering with the mounting portion 13a3 on the lateral beams 13.

[0346] In some embodiments, please refer to Figure 14 The mounting portion 13a3 is provided on the first sub-beam 13a1 and / or the second sub-beam 13a2, and in the first direction F1 and / or the second direction F2, the distance L2 between the geometric centers of the orthographic projections of each two adjacent mounting portions 13a3 on the second area hb is 80 mm-500 mm.

[0347] For an introduction to the first sub-beam 13a1 and the second sub-beam 13a2, please refer to the above description and will not be further elaborated here. The two first sub-beams 13a1 extend along the first direction F1, and the two second sub-beams 13a2 extend along the second direction F2. Mounting portions 13a3 are provided on the first sub-beams 13a1 and / or the second sub-beams 13a2, respectively, so that the mounting portions 13a3 extend along the first direction F1 and / or the second direction F2, thereby forming a uniform mounting and fixing for external devices in multiple directions, further improving the connection between the external device and the housing 10.

[0348] Furthermore, it is defined that in a certain set direction, the distance between the geometric centers of the orthographic projections of each two adjacent mounting portions 13a3 on the second region hb and the distance between the geometric centers of adjacent mounting holes k1 are within a limited range, so as to ensure that the setting distance between the mounting holes k1 and the mounting holes k1 along the extension direction of the first sub-beam 13a1 and along the extension direction of the second sub-beam 13a2 is controllable, so that the vehicle body 200 is subjected to uniform force.

[0349] It can be understood that when the box body 10 includes the middle channel beam 16 , the middle channel beam 16 is located in the first area ha, so that the middle channel beam 16 can be located in the middle area of ​​the main body 11 .

[0350] In one embodiment, the housing 10 includes the main body 11 and the high-voltage chamber 15. The main body 11 defines the battery chamber s1. The high-voltage chamber 15 is disposed at the top of the main body 11 and located in the first region ha. The high-voltage chamber 15, either by itself or in conjunction with the main body 11, forms the high-voltage chamber s2. Since the first region ha forms the majority of the top of the main body 11, locating the high-voltage chamber 15 in the first region ha improves space utilization in the first region ha.

[0351] On the other hand, according to some embodiments of the present application, please refer to Figure 3 and Figure 4 The present application provides a battery 100, comprising the housing 10 and a battery cell 20 as described in any of the above embodiments, wherein the battery cell 20 is accommodated in a receiving cavity s. Since the battery 100 includes the housing 10, it has all the advantages of the housing 10, which will not be described in detail here.

[0352] In some embodiments, the battery 100 further includes a high-voltage box (not shown), and the box body 10 is formed with a battery cavity s1 and a high-voltage cavity s2 that are independently arranged from each other. The battery cavity s1 is used to accommodate the battery cell 20, and the high-voltage cavity s2 is used to accommodate the high-voltage box.

[0353] The high-voltage box is an important safety barrier for the battery pack 100. It is equipped with a high-voltage control system, which is mainly used to: connect or disconnect the high-voltage circuit according to the vehicle's electronic control requirements; provide current and leakage detection terminals; achieve controllable load cut-off when the external current of the battery pack 100 is too large; when a short circuit occurs in the external circuit of the battery pack 100, the high-voltage circuit is disconnected to prevent the battery pack 100 from catching fire; when repairing the battery pack 100, the high-voltage circuit can be easily cut off.

[0354] At this time, the high-voltage box connects and collects the current of all battery cells 20 and provides safe power to the outside, thereby achieving safe external power supply of the battery 100. Regarding the specific structure of the high-voltage box, reference can be made to conventional settings in the field, and this application does not involve specific improvements to the high-voltage box.

[0355] In some embodiments, please refer to Figure 10 and Figure 20 The box body 10 includes a main body 11, which encloses a receiving cavity s. The main body 11 includes a carrier 11a located at the top of the box body 10 and used to define the receiving cavity s. The battery cell 20 is disposed on the carrier 11a.

[0356] The description of the main body 11, the top of the box 10, and the carrier 11a can be referred to above and will not be repeated here. In this case, the carrier 11a is a component capable of bearing the weight of the battery cell 20 and can be a carrier plate, a carrier block, a carrier sheet, a carrier frame, etc., without limitation.

[0357] Specifically, the battery cell 20 may be disposed below the carrier 11 a and bear the force on the top of the battery case 100 together with the carrier 11 a, thereby improving the rigidity of the top of the battery case 100 .

[0358] In some embodiments, please refer to Figure 10 and Figure 20 , the battery cell 20 is suspended on the supporting member 11a.

[0359] Suspending the battery cell 20 from the carrier 11a means that the battery cell 20 is positioned vertically below the carrier 11a, with the carrier 11a bearing the weight of the battery cell 20. Methods for suspending the battery cell 20 from the carrier 11a include: directly adhering the battery cell 20 to the lower surface of the carrier 11a; connecting the battery cell 20 to the carrier 11a via fasteners and positioned below the carrier 11a; or hanging the battery cell 20 from the carrier 11a via a hook or the like and positioned below the carrier 11a.

[0360] At this point, the battery cells 20 are suspended below the support member 11a, and the bottom cover 11c is located at the bottom of the housing 10. When repairing the interior of the battery 100, the bottom cover 11c can be removed to expose the battery cells 20 without removing the support member 11a, making maintenance of the battery 100 more convenient. Furthermore, when repairing the battery 100, the battery cells 20 can be removed and installed on the support member 11a from below. In particular, when the support member 11a is at least part of the chassis of the vehicle 1000 and is subject to stress, the battery cells 20 can be removed and installed from below the support member 11a without removing the support member 11a, thus facilitating repair of the battery 100.

[0361] In some embodiments, the battery cell 20 is bonded to the carrier 11 a .

[0362] Specifically, the battery cell 20 and the carrier 11a can be bonded with adhesives such as epoxy resin glue, acrylate glue, etc., which are not particularly limited. In this case, the bonding between the battery cell 20 and the carrier 11a not only facilitates the connection but also simplifies the structure of the battery 100.

[0363] Figure 22 Schematic diagram of the structure of the battery cell 20 in some embodiments of the present application.

[0364] In some embodiments, please refer to Figure 22 The outer surface of the battery cell 20 facing the carrier 11 a is a first outer surface m1 . The battery cell 20 includes an electrode terminal 21 a . The electrode terminal 21 a is arranged on an outer surface of the battery cell 20 except the first outer surface m1 .

[0365] As described above, the electrode terminals 21a are used to electrically connect to the electrode assemblies 23 within the battery cells 20, thereby transmitting or receiving electrical energy from the battery cells 20. At least a portion of the electrode terminals 21a extend outside the battery cells 20 to provide external electrical connection. The series and parallel connection of the battery cells 20 is achieved by connecting their respective electrode terminals 21a in series or in parallel. The electrode terminals 21a are conductive to facilitate electrical transmission and can be aluminum, copper, or other materials.

[0366] The electrode terminal 21a is arranged on the outer surface of the battery cell 20 except the first outer surface m1. The first outer surface m1 faces the carrier 11a and is generally a smooth surface, on which there are no protruding or recessed structures such as the electrode terminal 21a and the injection hole. When the battery cell 20 is suspended on the carrier 11a, the first outer surface m1 is the outer surface of the battery cell 20 facing upward. Specifically, in one embodiment, the battery cell 20 includes the shell 22 and the end cover 21 mentioned above, and the shell 22 and the end cover 21 form the internal environment of the battery cell 20 to accommodate the electrode assembly 23. The end cover 21 is located at one end of the shell 22, and the electrode terminal 21a is arranged on the end cover 21. At this time, any outer surface of the shell 22 can be used as the first outer surface m1 of the battery cell 20.

[0367] The electrode terminal 21a includes a positive terminal and a negative terminal. The positive terminal is used to electrically connect to the positive electrode sheet in the electrode assembly 23, and the negative terminal is used to electrically connect to the negative electrode sheet in the electrode assembly 23. It should be noted that the positive terminal and the negative terminal can be arranged on the same outer surface of the battery cell 20 (such as a prismatic battery cell), or they can be arranged on two different outer surfaces of the battery cell 20 (such as a cylindrical battery cell). When the positive terminal and the negative terminal are arranged on two different outer surfaces of the battery cell 20, the first outer surface m1 is a surface of the battery cell 20 that is different from the two outer surfaces.

[0368] In addition to the battery cells 20, the battery 100 is typically also provided with components such as a sampling harness that electrically connects the battery cells 20, a high-voltage wiring harness, and a protective structure that protects the battery cells 20. In this case, the electrode terminals 21a are arranged on surfaces other than the first outer surface m1 of the battery cell 20. When the sampling harness, high-voltage wiring harness, protective structure, and other components are placed on the electrode terminals 21a, they are not restricted by the support 11a. Instead, these components can be arranged through the space between the battery cells 20 and other structures of the main body 11 other than the support 11a (e.g., through the space between the battery cells 20 and the bottom cover 11c and / or the space between the battery cells 20 and the inner side of the main body 11), further facilitating the arrangement of the components. Furthermore, because the first outer surface m1 is a smooth surface, the first outer surface m1 can be aligned with the support 11a. This allows for the battery cells 20 to be mounted on the support 11a without requiring space between the battery cells 20 and the support 11a, thereby improving the space utilization of the battery 100.

[0369] In some embodiments, please refer to Figure 22 The battery cell 20 has a second outer surface m2 disposed opposite to the first outer surface m1, and the electrode terminal 21a is arranged on the second outer surface.

[0370] The second outer surface m2 is an outer surface of the battery cell 20 that is disposed opposite to the first outer surface m1 . When the battery cell 20 is suspended on the supporting member 11 a , the second outer surface m2 is opposite to the bottom cover 11 c .

[0371] Furthermore, the battery cell 20 and the bottom cover 11c can be spaced apart. This can prevent external forces acting on the bottom cover 11c from being transmitted to the battery cell 20 and damaging the battery cell 20. In particular, when the battery 100 is installed at the bottom of the vehicle 1000 and the bottom cover 11c is at the lowest point of the battery 100, stones on the ground can easily fly to the bottom of the battery 100 and hit the bottom cover 11c during the driving of the vehicle 1000. At this time, the buffer space can interrupt the external force from being transmitted to the battery cell 20 and affecting the battery cell 20.

[0372] When the battery cell 20 is spaced apart from the bottom cover 11c, a buffer space is defined between the second outer surface m2 and the bottom cover 11c, and the portion of the electrode terminal 21a extending beyond the battery cell 20 is located within this buffer space. Thus, the wiring harness and connector connected to the electrode terminal 21a can be arranged within the buffer space. Furthermore, the buffer space also has the aforementioned function of preventing external forces striking the bottom cover 11c from damaging the battery cell 20. Therefore, the buffer space not only interrupts external forces but also facilitates the layout of wiring harnesses, achieving two goals at once. Furthermore, the space utilization of the buffer space and the battery 100 is improved.

[0373] On the other hand, the present application also provides an electrical device. The electrical device includes the battery 100 provided in any of the above embodiments, and the battery 100 is used to provide power to the electrical device. For an introduction to the electrical device, please refer to the description above and will not be repeated here.

[0374] Since the electrical device includes the battery 100 , it has all the beneficial effects of the above embodiments, which will not be described in detail here.

[0375] Figure 1 This is a schematic diagram of a battery 100 applied to a vehicle body 200 in some embodiments of the present application.

[0376] In some embodiments, the electric device includes a vehicle 1000, and the battery 100 is disposed at the bottom of the vehicle body 200 of the vehicle 1000. For an introduction to the vehicle 1000, refer to the above description and will not be repeated here.

[0377] The body 200 of the vehicle 1000 refers to the portion of the vehicle 1000 used to carry people and cargo, including the cockpit, passenger compartment, engine compartment, luggage compartment, etc. The body 200 generally includes an outer shell and doors, windows, decorative parts, seats 300, air conditioning devices, etc. provided on the outer shell. The outer shell generally refers to the structure composed of the main load-bearing components such as the longitudinal beams, cross beams, chassis and pillars of the vehicle 1000 and the sheet metal parts connected thereto. In the embodiments of the present application, the battery 100 being provided at the bottom of the body 200 mainly refers to the battery 100 being provided at the bottom of the outer shell.

[0378] In this case, the battery 100 is disposed at the bottom of the vehicle body 200 , which does not occupy the space inside the vehicle body 200 and helps to reduce the volume and weight of the vehicle body 200 .

[0379] In some embodiments, the battery 100 is connected to the vehicle body 200 via the top of the housing 10 , and the top of the housing 10 is configured to form at least a portion of the chassis of the vehicle body 200 .

[0380] The chassis, as a part of the vehicle body 200, is composed of a combination of four parts: the transmission system, the running system, the steering system and the braking system. It is used to support and install the engine of the vehicle 1000 and its various components and assemblies, forming the overall shape of the vehicle 1000, bearing the engine power and ensuring normal driving.

[0381] The top of the chassis 10 located at the bottom of the vehicle body 200 directly serves as at least a portion of the chassis. In other words, the top of the chassis 10 forms at least a portion of the chassis of the vehicle body 200. This integration of the top of the chassis 10 and the chassis of the vehicle body 200 allows the space between the conventional chassis and the battery 100 to be allocated to the battery 100, increasing the battery's capacity. This helps increase the energy content of the battery 100 and, in turn, improves the vehicle's 1000 range.

[0382] According to some embodiments of the present application, an electrical device includes a vehicle 1000, with a battery 100 disposed at the bottom of the vehicle body 200. The battery 100 includes a housing 10 and battery cells 20. The housing 10 includes a support 11a located at the top thereof. The battery cells 20 are located within the housing 10 and suspended from the support 11a. The electrode terminals 21a of the battery cells 20 are located on the outer surface of the battery cells 20 facing away from the support 11a. The support 11a forms at least a portion of the chassis of the vehicle 1000. In this case, the battery 100 is suspended solely from the support 11a, which can improve the strength of the support 11a and, in turn, the strength of the top of the battery cells 20, enabling the support 11a to meet certain force requirements when used as a chassis. At the same time, the electrode terminal 21a of the battery cell 20 is away from the carrier 11a, so the battery cell 20 can be directly installed on the carrier 11a, eliminating the gap between the battery cell 20 and the carrier 11a, and the saved gap can be used to increase the installation space of the battery cell 20, which can increase the energy of the battery 100 and thus improve the endurance of the vehicle 1000.

[0383] According to some embodiments of this application, please refer to Figure 1 、 Figure 4 、 Figures 13 and 14 The electrical device includes a vehicle, and a battery is provided at the bottom of the vehicle body. The battery includes a housing and a battery cell. The housing includes a top surface facing away from the accommodating cavity. The top surface is formed with a first area, a second area, and a sealing area located therebetween. The sealing area surrounds the first area and is used to install a seal. The second area is constructed with a plurality of mounting holes, and the battery is mounted on an external device through the mounting holes so that the seal is in sealed contact with the external device. In addition, the shortest distance between the geometric center of the orthographic projection of the mounting portion on the second area and the outer edge of the sealing area is 50mm-100mm, so as to ensure the sealing isolation effect of the seal on the first area and the second area, while at the same time ensuring the connection strength between the battery and the external device.

[0384] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
