Description

Technical Field

[0001] This application relates to the field of battery technology, and in particular to housings, batteries and electrical devices. Background Technology

[0002] With the increasing maturity of new energy technologies, new energy vehicles are gradually entering the public eye. The core technology of new energy vehicles lies in the battery, and the safety and stability of the battery directly determine the performance of the entire vehicle.

[0003] A battery typically consists of individual battery cells and a high-voltage box, through which the battery cells supply power to the outside. In related technologies, when individual battery cells experience thermal failure and generate excessive heat, the components inside the high-voltage box can be easily damaged, reducing battery safety. Summary of the Invention

[0004] In view of this, this application provides a battery and an electrical device designed to improve battery safety.

[0005] In a first aspect, this application provides a housing for a battery, the housing having a battery cavity and a high-voltage cavity that are independently arranged from each other, the battery cavity for accommodating individual battery cells and the high-voltage cavity for accommodating a high-voltage box.

[0006] In the solution of this application, when the battery chamber and the high-voltage chamber are set up independently, the high-temperature gas leaked by the thermal failure of the battery cell in the battery chamber will not enter the high-voltage box, and thus will not cause thermal damage to the high-voltage control system in the high-voltage box. This can ensure the normal control function of the high-voltage control system and improve the safety performance of the battery.

[0007] In some embodiments, the housing includes a main body and a high-voltage chamber. A battery cavity is formed within the main body, and the high-voltage chamber is located outside the main body, either enclosing itself or jointly enclosing the high-voltage chamber with the main body. In this case, the high-voltage chamber is defined by the high-voltage chamber located outside the main body, and the receiving cavity formed by the main body can serve as a housing for battery cells, thereby increasing the battery's capacity.

[0008] In some embodiments, the high-voltage compartment protrudes from the top of the main body. When the battery housing is used as the chassis of a vehicle, the high-voltage compartment is located on top of the main body and is therefore protected from external impacts (such as stones kicked up during vehicle operation), making it safer.

[0009] In some embodiments, the high-pressure chamber is located near the top outer edge of the main body. In this case, the high-pressure chamber can be arranged corresponding to the passenger space behind the driver's space of the vehicle, and in particular, it can be arranged corresponding to the underside of the passenger seat, without occupying the vehicle's movement space.

[0010] In some embodiments, the main body includes a carrier and a frame. The frame encloses a cavity with at least its top end extending through it. The carrier covers the top end of the cavity, and the carrier and the frame together form at least a partial receiving cavity. The high-pressure chamber is disposed on top of the carrier and either encloses itself or together with the carrier to form a high-pressure chamber. In this case, since the carrier constitutes most of the top area of ​​the main body, placing the high-pressure chamber on top of the carrier provides more space for installation and makes the installation more stable.

[0011] In some embodiments, the top of the housing is provided with a mounting section, through which the battery is mounted to an external device. The mounting section refers to a dedicated structure provided on the top of the housing 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 section, and the other end can be connected to the external device to securely connect the battery to the external device.

[0012] In some embodiments, the mounting portion includes at least one mounting hole located on the top of the housing. The mounting hole can be formed on the top of the housing by drilling, and the mounting hole allows the connector to pass through itself and be fixed to the structure with the mounting hole, thereby connecting the external device to the top of the housing via the connector.

[0013] In some embodiments, the housing further includes a seal located at the top of the housing for a sealed connection with an external device. In this case, the battery housing achieves a sealed connection with the external device through the seal, which is reliable and cost-effective.

[0014] In some embodiments, the top surface of the housing has a first region, a second region, and a sealing region located between the two. The sealing region surrounds the first region, a seal is installed in the sealing region, and a mounting portion is constructed in the second region. By constructing the mounting portion in the second region, the housing is connected to the vehicle body through a relatively outer area of ​​the top. In this case, the housing is only subjected to vertical forces from the vehicle body, reducing the force transmission path and improving the overall vehicle rigidity and lateral compression resistance.

[0015] In some embodiments, the housing includes a main body and a high-voltage compartment. A battery cavity is formed within the main body, and the high-voltage compartment is located on the top of the main body and in a first region. The high-voltage compartment either encloses itself or, together with the main body, forms the high-voltage cavity. Since the first region forms most of the area on the top of the main body, arranging the high-voltage compartment in the first region can improve the space utilization of the first region.

[0016] Secondly, this application also provides a battery, including the aforementioned housing, battery cell, and high-voltage box, wherein the battery cell is housed in the battery cavity and the high-voltage box is housed in the high-voltage cavity.

[0017] In some embodiments, the housing includes a main body that encloses a receiving cavity. The main body includes a support member located at the top of the housing and used to define the battery cavity, and individual battery cells are disposed on the support member. The individual battery cells are disposed below the support member and share the load on the top of the battery housing with the support member, thereby improving the rigidity of the top of the battery housing.

[0018] In some embodiments, the battery cells are suspended on a carrier, with the bottom cover located at the bottom of the housing. When performing internal battery maintenance, the battery cells can be exposed by removing the bottom cover without removing the carrier, making battery maintenance more convenient. Furthermore, during battery repair, the battery cells can be installed and removed from the carrier from below. This is particularly useful when the carrier is at least part of the vehicle chassis and bears stress; in such cases, the battery cells can be installed and removed only from below the carrier without disassembling the carrier itself, facilitating battery maintenance.

[0019] In some embodiments, the battery cells are bonded to the carrier. Bonding the battery cells to the carrier not only facilitates connection but also simplifies the battery structure.

[0020] In some embodiments, the outer surface of the battery cell facing the carrier is the first outer surface. 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, with the electrode terminals located on the outer surface of the battery cell other than the first outer surface, various components connecting 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, making the arrangement of each component more convenient. Furthermore, by connecting the battery cell to the carrier through the first outer surface without electrode terminals, the battery cell and the carrier can be fitted together, saving space between the battery cell and the carrier and improving the space utilization rate of the battery.

[0021] In some embodiments, the battery cell has a second outer surface disposed opposite to the first outer surface, and electrode terminals are arranged on the second outer surface. In this case, a buffer space exists between the second outer surface and the bottom cover, and the portion of the electrode terminals extending beyond the battery cell is located within this buffer space. Thus, wiring harnesses and connecting pieces connected to the electrode terminals can be arranged within the buffer space. Simultaneously, the buffer space can also prevent external forces striking the bottom cover from damaging the battery cell. Therefore, the buffer space not only interrupts the influence of external forces but also allows for the arrangement of wiring harnesses, etc., achieving two benefits at once.

[0022] Thirdly, this application also provides an electrical device, including the aforementioned battery, which is used to provide electrical energy to the electrical device.

[0023] In some embodiments, the electrical device includes a vehicle, and the battery is disposed at the bottom of the vehicle body. In this case, placing the battery at the bottom of the vehicle body does not occupy interior space, which helps to reduce the vehicle's size and weight.

[0024] 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 occupied by the gap between the conventional chassis and the battery can be allocated within the battery to increase battery space, which helps to increase battery energy and thus improve the vehicle's range.

[0058] Currently, judging from market trends, battery applications are becoming increasingly widespread. Batteries are not only used in energy storage systems such as hydropower, thermal power, wind power, and solar power plants, but also extensively in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. With the continuous expansion of battery applications, market demand is also constantly increasing.

[0059] The inventors have noticed that in related technologies, the battery cells and the high-voltage box are located in the same space within the battery. When the battery cells fail thermally, they release a large amount of heat. Since the high-voltage box is located in the same space as the battery cells, it will be affected by the heat released by the battery cells. The high-voltage control system installed inside the high-voltage box is easily damaged by heat, causing the high-voltage control system to become uncontrollable and leading to a safety accident, which greatly reduces the safety of the battery.

[0060] To improve battery safety, the applicant discovered that the space where the high-voltage box is located can be separated from the space where the individual battery cells are located, thus preventing the heat generated by the individual battery cells from damaging the high-voltage control system inside the high-voltage box.

[0061] Based on the above considerations, and to improve battery safety, the inventors, through in-depth research, designed a housing for the battery. The housing comprises an independently configured battery chamber and a high-voltage chamber. The battery chamber houses the individual battery cells, while the high-voltage chamber houses the high-voltage box. Because the battery chamber and high-voltage chamber are independently configured, high-temperature gases leaking from a single battery cell in the battery chamber due to thermal failure will not enter the high-voltage box, thus preventing thermal damage to the high-voltage control system within the high-voltage box. This ensures the normal control function of the high-voltage control system and improves battery safety.

[0062] The batteries disclosed in this application can be used, but are not limited to, in electrical devices such as vehicles, ships, or aircraft. A power system for such an electrical device can be constructed using batteries disclosed in this application. The mounting structure involved in this application is a structure used to mount batteries in an electrical device.

[0063] This application provides an electrical device that uses a battery as a power source. The electrical device can be, but is not limited to, mobile phones, tablets, laptops, electric toys, power tools, electric vehicles, electric cars, ships, spacecraft, etc. Electric toys can include stationary or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, etc. Spacecraft can include airplanes, rockets, space shuttles, and spacecraft, etc.

[0064] For ease of explanation, the following embodiments will be described using a vehicle 1000 as an example of an electrical device according to an embodiment of this application.

[0065] Please refer to Figure 1 , Figure 1This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. A battery 100 is disposed inside the vehicle 1000, and the battery 100 can be located at the bottom, front, or rear of the vehicle 1000. The battery 100 can be used to power the vehicle 1000; for example, the battery 100 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller and a motor. The controller is used to control the battery 100 to supply power to the motor, for example, to meet the power needs of the vehicle 1000 during startup, navigation, and driving.

[0066] In some embodiments of this application, the battery 100 can not only serve as the operating power source for the vehicle 1000, but also as the driving power source for the vehicle 1000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000.

[0067] Please refer to Figure 2 , Figure 2 This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. A battery cell 20 refers to the smallest unit that makes up the battery 100. For example... Figure 2 As shown, the battery cell 20 includes an end cap 21, a housing 22, an electrode assembly 23, and other functional components.

[0068] End cap 21 refers to a component that covers the opening of housing 22 to isolate the internal environment of battery cell 20 from the external environment. The shape of end cap 21 can be adapted to the shape of housing 22 to fit it. Optionally, end cap 21 can be made of a material with certain hardness and strength (such as aluminum alloy), so that end cap 21 is not easily deformed under pressure and impact, giving battery cell 20 higher structural strength and improved safety. Functional components such as electrode terminals 21a can be provided on end cap 21. Electrode terminals 21a can be used for electrical connection with electrode assembly 23 to output or input electrical energy to battery cell 20. In some embodiments, end cap 21 can also be provided with a pressure relief mechanism for releasing internal pressure when the internal pressure or temperature of battery cell 20 reaches a threshold. The material of end cap 21 can also be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., and this application embodiment does not impose any special limitations on this. In some embodiments, an insulating element may be provided on the inner side of the end cap 21. The insulating element can be used to isolate the electrical connection portion 11a2 within the housing 22 from the end cap 21 to reduce the risk of short circuit. For example, the insulating element may be made of plastic, rubber, etc.

[0069] The housing 22 is a component used to cooperate with the end cap 21 to form the internal environment of the battery cell 20. This internal environment can accommodate the electrode assembly 23, electrolyte, and other components. The housing 22 and the end cap 21 can be independent components. An opening can be provided on the housing 22, and the end cap 21 can be used to close the opening to form the internal environment of the battery cell 20. Alternatively, the end cap 21 and the housing 22 can be integrated. Specifically, the end cap 21 and the housing 22 can form a common connecting surface before other components are inserted into the housing. When it is necessary to encapsulate the interior of the housing 22, the end cap 21 closes the housing 22. The housing 22 can be of various shapes and sizes, such as cuboid, cylindrical, hexagonal prism, etc. Specifically, the shape of the housing 22 can be determined according to the specific shape and size of the electrode assembly 23. The material of the housing 22 can be various, such as copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc. This application embodiment does not impose any special limitations on this.

[0070] Electrode assembly 23 is the component in the battery cell 20 where electrochemical reactions occur. The casing 22 may contain one or more electrode assemblies 23. The electrode assembly 23 is mainly formed by winding or stacking positive and negative electrode sheets, and typically a separator is provided between the positive and negative electrode sheets. The portions of the positive and negative electrode sheets containing active material constitute the main body 11 of the electrode assembly 23, while the portions without active material are formed separately. The positive and negative electrode tabs may be located together at one end of the main body 11 or at opposite ends of the main body 11. During the charging and discharging process of the battery, the positive and negative active materials react with the electrolyte, and the tabs connect to the electrode terminals 21a to form a current loop.

[0071] Figure 3 The following is an exploded view of a battery 100 provided in some embodiments of this application. The battery 100 includes a battery cell 20 and a housing 10, the housing 10 having a receiving cavity s for accommodating the battery cell 20.

[0072] In battery 100, there can be multiple battery cells 20, which can be connected in series, parallel, or in a mixed manner. A mixed connection means that multiple battery cells 20 are connected in both series and parallel configurations. Multiple battery cells 20 can be directly connected in series, parallel, or in a mixed manner, and then the entire assembly of the multiple battery cells 20 is housed within the casing 10. Alternatively, battery 100 can also consist of multiple battery cells 20 first connected in series, parallel, or in a mixed manner to form a battery module, and then multiple battery modules are connected in series, parallel, or in a mixed manner to form a whole, which is also housed within the casing 10. Battery 100 may also include other structures; for example, it may include a busbar component for electrical connection between multiple battery cells 20. Each battery cell 20 can be a secondary battery or a primary battery; it can also be a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery, but is not limited to these. Battery cells 20 can be cylindrical, flat, cuboid, or other shapes.

[0073] The box 10 can be in various shapes, such as a cylinder or a cuboid, and the specific structure of the box 10 can adopt various structural methods.

[0074] According to some embodiments of this application, please refer to Figure 3 This application provides a housing 10 for a battery 200, the housing 10 having a receiving cavity s for accommodating a battery cell 20. The housing 10 provides housing space for the battery cell 20, and the housing can adopt various structures. In some embodiments (e.g.) Figure 3 As shown, the housing may include a first part 10A and a second part 10B, which overlap each other, together defining a space for accommodating individual battery cells. The second part 10A may be a hollow structure with one open end, and the first part 10A may be a plate-like structure, overlapping the open side of the second part so that the first part 10A and the second part 10B together define the accommodating space. Alternatively, both the first part 10A and the second part 10B may be hollow structures with one open side, overlapping the open side of the second part 10B. Of course, the housing 10 formed by the first part 10A and the second part 10B can be of various shapes, such as a cylinder, a cuboid, etc.

[0075] Figure 4 This is another exploded view of the battery 100 in some embodiments of this application. Figure 5 for Figure 4 Enlarged view of point A in the middle. Figure 6 This is a partial structural diagram of the battery 100 in some embodiments of this application. Figure 7 for Figure 6 An enlarged view of point B in the structure shown. Figure 8 for Figure 6Top view of the structure, Figure 9 for Figure 6 Side view of the structure described. Figure 10 for Figure 9 The cross-sectional view of the structure shown at point C.

[0076] In some embodiments, please refer to Figure 4 The battery 100 is mounted on the external device via the top of the housing 10.

[0077] The top of the enclosure 10 includes the top surface h of the enclosure 10 and other structures disposed on the top surface h of the enclosure 10. The top surface h of the enclosure 10 refers to the upper surface of the enclosure 10 in the vertical direction when in use. Other structures disposed on the top surface h of the enclosure 10 include, but are not limited to, connectors (such as bolts, rivets, etc.) that connect the top surface h of the enclosure 10 to external devices, and sealing structures (such as sealing strips) that seal the enclosure 10 to external devices.

[0078] External devices refer to devices used for mounting the housing 10. External devices can be partial structures within the aforementioned electrical devices used for mounting the housing 10, or other structures within the electrical device that together with the battery 100 form the electrical device. Taking a vehicle 1000 as an example, the external device can be the vehicle body 200, and the battery 100 can be mounted on the bottom of the vehicle body 200 and then on the vehicle body 200 via its top.

[0079] At this time, the battery 100 is mounted on the external device through the top of the housing 10. Compared with the arrangement of the housing 10 located at the bottom of the external device, the connection structure between the housing 10 and the external device is smaller in size, lower in cost, and more compact.

[0080] 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 housing 10.

[0081] In some embodiments, please refer to Figure 4 The box 10 includes a main body 11, which encloses and forms a receiving cavity s.

[0082] The main body 11 can be a one-piece structure or assembled from multiple parts. Understandably, the main body 11 is a hollow, shell-like structure that encloses a receiving cavity s. Specifically, the main body 11 can be assembled from 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 open end, and the second sub-part covers the open end of the receiving cavity s. In another example, the first sub-part encloses a first space with one open end, and the second sub-part encloses a second space with one open end; the two open ends of the first and second sub-parts overlap to form a receiving cavity s composed of the first and second spaces. The first and second sub-parts can be welded, snap-fitted, or fastened together. The first and second sub-parts can be made of plastic, metal, or other materials.

[0083] In some embodiments, please refer to Figure 4 The top of the main body 11 forms at least a portion of the top of the box 10.

[0084] The top of the main body 11 refers to the structure located at the uppermost position in the vertical direction of the main body 11. The uppermost position of the main body 11 is also the uppermost position of the box 10, such that the top of the main body 11 forms at least a part of the top of the box 10. When the top of the main body 11 forms the entire top of the box 10, then the top of the main body 11 is the top of the box 10, and the entire top of the box 10 participates in defining the receiving cavity s. When the top of the main body 11 forms only a part of the top of the box 10, the top of the box 10 also has other structures that do not participate in defining the receiving cavity s, such as the lateral beam 13 described below, for details.

[0085] When the battery 100 is installed on the external device via the top of the housing 10, the top of the main body 11 is also located in the position of the battery 100 closest to the external device. 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.

[0086] Understandably, please refer to Figure 6 The main body 11 has circumferential sidewalls n arranged around its top outer edge.

[0087] 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. The bottom can be a bottom surface and a structure set on the bottom surface, or a bottom opening.

[0088] The outer surface of the structure sandwiched between the top and bottom, facing away from the receiving cavity s, forms a circumferential sidewall n. The plane containing the circumferential sidewall n extends in a direction that intersects with the plane containing the top. The circumferential sidewall n can be a ring, a quadrilateral shape, etc., formed by multiple wall segments joined end to end, as detailed below.

[0089] Understandably, please refer to Figure 6 The housing 10 also has a top surface h facing away from the receiving cavity s.

[0090] The top surface h of the housing 10 is located on the side of the top of the housing 10 that faces away from the receiving cavity s. When the battery 100 is mounted to an external device via the top of the housing 10, the top surface h faces the external device and forms the position of the battery 100 that is closest to the external device.

[0091] In some embodiments, please refer to Figure 6 The top surface h of the housing 10 is configured to contact an external device (not shown) on which the battery 100 is installed.

[0092] The battery 100 is mounted on the external device through the top of the housing 10, and the surface of the housing 10 facing away from the receiving 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 where the top surface h of the housing 10 does not contact the external device, the connection structure between the housing 10 and the external device is smaller, less expensive and more compact.

[0093] In some embodiments, please refer to Figure 6 The top of the housing 10 has a mounting part 13a3, through which the battery 100 is mounted to an external device.

[0094] The mounting portion 13a3, as part of the top of the housing 10, does not participate in the definition of the receiving cavity s. The mounting portion 13a3 refers to a dedicated structure provided on the top of the housing 10 for connection with external devices via connectors (such as bolts, rivets, etc.). 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 securely connect the battery 100 to the external installation. Understandably, the top of the main body 11 is at least part of the top of the housing 10, and the mounting portion 13a3 can be provided on the top of the main body 11, or it can be provided on other structures that form the top of the housing 10 (such as the top of the side beam 13 mentioned below).

[0095] When the battery 100 is installed on the external device via the mounting part 13a3, the top surface h of the housing 10 is in contact with the external device, which improves the connection strength and ensures the compactness of the connection structure between the housing 10 and the external device.

[0096] The mounting part 13a3 may also have a connecting function (such as a lifting ring), and a corresponding connector (such as a hook) can be provided on the external device to directly connect to the mounting part 13a3. In other embodiments, a connector may not be provided, and the connection between the mounting part 13a3 and the external device may be achieved directly by other means, including but not limited to snap-fit, plug-in, threaded connection, riveting, welding, and bonding, which are not specifically limited here.

[0097] In some embodiments, please refer to Figure 6 The mounting part 13a3 includes at least one mounting hole k1 located on the top of the housing 10.

[0098] The mounting holes k1 can be formed on the top of the housing 10 by drilling. All mounting holes k1 have holes and openings that communicate with both ends of the holes. The holes and openings that communicate with both ends of the holes allow the connector to pass through itself and be fixed to the structure with the mounting holes k1, thereby connecting the external device to the top of the housing 10 through the connector.

[0099] The connector can be a rivet, with a fixing hole 11c3 provided at the position corresponding to the mounting hole k1 on the external device. After the rivet passes through the fixing hole 11c3 and the mounting hole k1, the two are fixed by a nut. Alternatively, the connector can be a screw, with the mounting hole k1 being a threaded hole. The screw passes through the mounting hole k1 and is threaded to connect with the housing 10.

[0100] Specifically, all mounting holes k1 can be extended vertically to fix the battery 100 to the bottom of the external device vertically. Understandably, in order to achieve the connection stability between the top of the housing 10 and the external device and the uniformity of force between the two, the setting position and setting distance of all mounting holes k1 can be controlled, as detailed below.

[0101] Understandably, in addition to the mounting hole k1, the mounting part 13a3 may also include other structures that enable mounting, such as hooks.

[0102] In some embodiments, please refer to Figure 4 and Figure 6 The main body 11 includes a support member 11a and a frame 11b. The frame 11b encloses a cavity with at least its top end through it. The support member 11a covers the top end of the cavity. The support member 11a and the frame 11b enclose at least a partial receiving cavity s.

[0103] The frame 11b encloses a cavity, with at least its top end extending through it. The support member 11a covers the top of the cavity; that is, the support member 11a is located on the top of the housing 10 and defines the receiving cavity s. The frame 11b and the support member 11a can be made of the same material, such as aluminum alloy, copper alloy, steel, or plastic. Of course, the frame 11b, the support member 11a, and the bottom cover 11c can also be made of different materials; there is no specific limitation. In its vertical orthographic projection, the frame 11b can be rectangular, circular, polygonal, etc.; there is no specific limitation. The support member 11a can be a support plate, support sheet, support block, or other structure.

[0104] The top surface h1 of the main body 11 can be entirely formed by the top surface of the support member 11a, in which case the entire frame 11b is located below the support member 11a. Alternatively, the top surface h1 of the main body 11 can be formed by the top surface of the support member 11a and the top surface of the frame 11b together, in which case the support member 11a is located inside the frame 11b, and the top surface of the support member 11a and the top surface of the frame 11b can be either coplanar or non-coplanar.

[0105] The support component 11a is fixedly connected to the frame 11b or integrally formed. The support component 11a and the frame 11b are integrally formed by injection molding, die casting, forging, cold pressing, hot pressing, etc. The support component 11a and the frame 11b can be fixedly connected by fasteners, snap-fit ​​structures, welding, bonding, hot-melt connection, etc.

[0106] The circumferential sidewall n of the main body 11 is mainly formed by the circumferential sidewall n of the frame 11b, which is the outer surface of the frame 11b surrounding the support member 11a and opposite to the cavity defined by it.

[0107] In some embodiments, please refer to Figure 4 and Figure 5 The main body 11 also includes a bottom cover 11c, which together with the support member 11a and the frame 11b forms a cavity s for accommodating the battery cell 20.

[0108] Understandably, the cavity of the frame 11b extends through the bottom of the frame 11b, and the bottom cover 11c covers the bottom of the frame 11b, forming the receiving cavity s of the box 10 together with the frame 11b and the carrier 11a.

[0109] Specifically, the bottom cover 11c can be, but is not limited to, a plate-like structure, a block-like structure, etc., and can be flat, curved, etc., without specific limitations. When the battery cell 20 is located in the receiving cavity s, the battery cell 20 can be disposed on the bottom cover 11c and / or the support member 11a and / or the frame 11b.

[0110] The bottom cover 11c and the frame 11b can be fixed together by welding, hot-melt connection, bonding, fastening, snap-fitting, etc. Fastening refers to the connection achieved through fasteners 11c4, which include bolts, pins, rivets, dowels, screws, etc. Snap-fitting refers to fixing through a snap-fit ​​structure; for example, the bottom cover 11c has a hook, and the frame 11b has a latch; when the hook engages in the latch, the bottom cover 11c and the frame 11b are locked together. Of course, the connection methods between the bottom cover 11c and the frame 11b are not limited to these, and are not exhaustively described in this application.

[0111] At this point, based on the frame 11b, the bearing 11a and the bottom cover 11c are connected to the two ends of the frame 11b in the vertical direction to form the receiving cavity s of the battery 100, and the structure of the main body 11 is relatively simple.

[0112] 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 surrounds and is connected to the edge of the cover portion 11c1. The cover portion 11c1 is used to define the receiving cavity s. The mounting portion 11c2 is connected to the frame 11b.

[0113] The cover portion 11c1 defines the receiving cavity s. This means that the cover portion 11c1, together with the supporting member 11a and the frame 11b, forms the receiving cavity s. The mounting portion 11c2 connects to the frame 11b and does not participate in defining the receiving cavity s. The cover portion 11c1 can be a plate-shaped or block-shaped component, or a flat or curved plate-shaped component; its specific form is not limited. Figure 4 and Figure 5 It can be seen that the mounting part 11c2 surrounding the edge of the cover part 11c1 means that the mounting part 11c2 is continuously arranged along the edge of the cover part 11c1 in a closed-end structure. Understandably, in the vertical projection, the mounting part 11c2 has a certain width, so that there is an appropriate contact area between it and the frame 11b, so as to facilitate the positioning and installation of the mounting part 11c2 and the frame 11b.

[0114] The cover 11c1 and the mounting part 11c2 can be integrally molded. When the bottom cover 11c is made of metal (such as aluminum, iron, stainless steel, etc.), the cover 11c1 and the mounting part 11c2 can be integrally molded 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), the cover 11c1 and the mounting part 11c2 can be integrally molded by injection molding. The cover 11c1 and the mounting part 11c2 can also be molded separately and then connected together. When the cover 11c1 and the mounting part 11c2 are made of metal, they can be welded or bonded together. When the cover 11c1 and the mounting part 11c2 are made of plastic, they can be bonded together. Of course, the cover 11c1 and the mounting part 11c2 can also be fixedly connected together by other means such as snap-fitting or riveting.

[0115] 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 support member 11a are both in the same plane, and / or the two surfaces of the cover portion 11c1 and the mounting portion 11c2 facing away from the support member 11a are both in the same plane. When the two surfaces of the cover portion 11c1 and the mounting portion 11c2 facing the support member 11a and the two surfaces facing away from the support member 11a are both in the same plane, the cover portion 11c1 and the mounting portion 11c2 can form a flat bottom cover 11c.

[0116] 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 towards the support member 11a, or the cover portion 11c1 may protrude away from the support member 11a relative to the mounting portion 11c2; the specific design is not limited. The thickness of the cover portion 11c1 and the mounting portion 11c2 may be equal or unequal; the specific design is not limited.

[0117] At this time, the bottom cover 11c defines the receiving cavity s via the cover part 11c1 and is connected to the frame 11b via the mounting part 11c2, with a clear structure and convenient installation.

[0118] Understandably, 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 part 11c2, that is, the mounting part 11c2 is detachably connected to the frame 11b. The detachable connection between the mounting part 11c2 and the frame 11b is achieved simply by setting the portion of the bottom cover 11c that is detachably connected to the frame 11b as the mounting part 11c2.

[0119] In some embodiments, the mounting part 11c2 is detachably connected to the frame 11b.

[0120] Specifically, the bottom cover 11c also includes a fixing hole 11c3 provided on the mounting part 11c2. The fastener 11c4 passes through the fixing hole 11c3 on the mounting part 11c2 and is then fastened to the frame 11b. The fixing hole 11c3 is a through hole that penetrates the mounting part 11c2 in the vertical direction. Specifically, the fixing hole 11c3 can be a smooth through hole (such as when the fastener 11c4 is a rivet), a threaded through hole (such as when the fastener 11c4 is a screw), or a through hole of other types (such as a hexagonal hole, a square hole, an oblong hole, etc.). The specific form of the fixing hole 11c3 depends on the specific form and specific setting method of the fastener 11c4, and will not be elaborated here.

[0121] In some embodiments, please refer to Figure 6 , Figure 8 and Figure 9 The box body 10 includes a side beam 13, which is located on the circumferential side wall n of the main body 11.

[0122] The side beam 13 refers to a beam structure installed on the circumferential sidewall n of the main body 11 to strengthen the main body 11. Understandably, the side beam 13 is located outside the main body 11. Specifically, the main body 11 and the side beam 13 are integrally connected as a whole, or they can be connected as a whole by assembly. Integral connection methods include, but are not limited to, welding, integral molding, and fusion. Assembly connection methods include, but are not limited to, snap-fitting and fastening.

[0123] The lateral beams 13 can be arranged on all or only on a portion of the circumferential sidewalls n of the main body 11. Regardless of type, the lateral beams 13 are arranged around the circumferential sidewalls n of the main body 11, thus strengthening the main body 11 from multiple lateral directions. Specifically, the lateral beams 13 can be continuously or intermittently arranged around the circumferential sidewalls n of the main body 11. When continuously arranged, the lateral beams 13 can be in the form of a ring beam; when intermittently arranged, the lateral beams 13 can include multiple beam portions spaced apart around the circumferential sidewalls n of the main body 11.

[0124] In a practical application scenario, the housing 10 is used for the battery 100, and the battery 100 is used for the vehicle 1000. The top of the housing 10 is mounted on the vehicle 1000, and the top of the housing 10 forms the chassis structure of the vehicle 1000. When the battery housing 10 is used as the chassis of the vehicle 1000, the lateral structure of the housing 10 is easily compressed by external impacts (such as stones flying during the vehicle 1000's operation hitting the lateral position of the housing 10, or being impacted laterally by other vehicles 1000). In this case, 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 compression resistance of the housing 10 and also improving the lateral compression resistance of the vehicle 1000, thus enhancing the safety of the vehicle 1000.

[0125] Understandably, when the main body 11 includes the aforementioned support member 11a and frame 11b, the lateral beam 13 is disposed on the circumferential sidewall n defined by the frame 11b.

[0126] The cavity formed by the frame 11b mainly constitutes the receiving cavity s of the housing 10. Since the receiving cavity s has a certain height to accommodate multiple battery cells 20, the frame 11b also has a certain height, resulting in a large circumferential sidewall n area of ​​the frame 11b. At this time, the side beam 13 is set on the circumferential sidewall n defined by the frame 11b, making the installation method, installation area, and arrangement of the side beam 13 more flexible.

[0127] In a further embodiment, the side beam 13 is fixedly connected to the frame 11b or integrally formed. The side beam 13 and the frame 11b can be fixedly connected by welding, fusion, riveting, threaded connection, etc., or they can be formed into one piece by integral processing (such as stamping, die casting).

[0128] When the side beam 13 and the frame 11b are integrally formed, the assembly process of the housing 10 can be reduced, and the production process of the housing 10 can be accelerated. When the side beam 13 and the frame 11b are fixedly connected, the forming process of the side beam 13 and the frame 11b is easier, which can reduce the process cost of the housing 10.

[0129] In some embodiments, please refer to Figure 10 The lateral beam 13 includes at least two sub-beams 13a, which are arranged sequentially at intervals along the circumferential sidewall n. The sub-beams 13a are the basic units that make up the lateral beam 13, and the positions of the lateral beams 13 can be flexibly arranged on the circumferential sidewall n of the main body 11 by setting the positions of the sub-beams 13a.

[0130] The lateral beam 13 is formed by at least two sub-beams 13a spaced apart along the circumferential sidewall n of the main body 11. This means that at least two sub-beams 13a are arranged spaced apart along the extension direction of the circumferential sidewall n to form an enclosing form around the main body 11, so as to strengthen the main body 11 from multiple lateral directions.

[0131] The sub-beams 13a can have various structural forms, and the structures of each sub-beam 13a can be the same or different. For example, sub-beam 13a can be a longitudinally extending solid beam, or it can be a longitudinally extending hollow beam. The cross-sectional shape of each sub-beam 13a can be H-shaped, U-shaped, or other structural forms.

[0132] At this point, the lateral beam 13 is formed by combining multiple sub-beams 13a. 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 less labor-intensive.

[0133] In some embodiments, continue to refer to Figure 10 At least one sub-beam 13a includes an upper arm beam 131 and a lower arm beam 132, with the upper arm beam 131 and the lower arm beam 132 arranged at intervals and connected to the main body 11.

[0134] The vertical direction corresponds to 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. Understandably, both the upper arm beam 131 and the lower arm beam 132 extend circumferentially along the main body 11 and are in contact with 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 are connected by the main body 11. A channel can be formed between them, which can serve as a weight-reduction structure or a structure for wiring harness routing.

[0135] At this point, the structure of the main body 11 is strengthened by the upper arm beam 131 and the lower arm beam 132. Because 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, making the external force on the box body 10 more even. Simultaneously, the upper arm beam 131 and the lower arm beam 132 are arranged vertically and horizontally, allowing the sub-beam 13a to withstand the compression of the vehicle 1000 in the front-rear or left-right directions, making it more suitable for the actual operating conditions of the vehicle 1000. Furthermore, the alternating arrangement of the upper arm beam 131 and the lower arm beam 132 can reduce the weight of the box body 10 and achieve other functions.

[0136] In other embodiments, an intermediate beam (not shown) may be provided between the upper arm beam 131 and the lower arm beam 132. The intermediate beam connects the upper arm beam 131 and the lower arm beam 132, which can further strengthen the structural strength of the sub-beam 13a and improve the lateral compression resistance of the box body 10.

[0137] 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 internal structure, meaning that the beam has space inside 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 not only reduces their own weight, thereby reducing the problem of high energy consumption caused by the heavy weight of the battery 100 when it is used in electrical devices such as vehicles 1000, but also allows the hollow beam structure to absorb lateral compressive forces through its internal space, reducing the degree of damage to the battery 100 under lateral compression.

[0138] In some embodiments, please refer to Figure 6 The circumferential sidewall n includes at least two first wall segments n1 that extend along the first direction F1 and are spaced apart; 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.

[0139] 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 can correspond to the front-rear direction of the vehicle 1000. The first wall segment n1 in the circumferential sidewall n of the main body 11 corresponds to the circumferential sidewall n in the left and right directions of the battery 100. The first wall segment n1 extends along the first direction F1, that is, along the front-rear direction of the vehicle 1000. The two first wall segments n1 are arranged at intervals in the left-right direction of the vehicle 1000. Each of the two first wall segments n1 is provided with a sub-beam 13a, and each sub-beam 13a has the same extending direction as each first wall segment n1.

[0140] The sub-beams 13a on each of the first wall segments n1 can have identical structures, thus ensuring consistent compressive strength on both 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 embodiments. In this case, the sub-beams 13a possess stronger compressive strength, compensating for the weaker structures on both sides of the vehicle 1000, thereby enhancing the compressive strength on both sides of the vehicle 1000 and improving the safety of the vehicle 1000.

[0141] At this time, the sub-beams 13a are set on each first wall segment n1, which can strengthen the structural strength of each first wall segment n1 and improve the compression resistance of each first wall segment n1. In other words, the compression resistance of the vehicle 1000 is improved. Understandably, 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-rear direction.

[0142] In some embodiments, continue to refer to Figure 6The circumferential sidewall n also includes two second wall segments n2 that extend along a second direction F2 perpendicular to the first direction F1 and are spaced apart from each other. The two first wall segments n1 and the two second wall segments n2 are connected alternately. The at least two sub-beams 13a also include two second sub-beams 13a2. The two second sub-beams 13a2 are respectively arranged on the two second wall segments n2 and both extend along the first direction F1.

[0143] In practical applications, the second direction F2 can correspond to the left and right directions of the housing 10. In this case, the second wall segment n2 corresponds to the circumferential sidewall n of the battery 100 in both the front and rear directions. The second wall segment n2 extends along the second direction F2, that is, it extends along the left and right directions of the vehicle 1000.

[0144] The sub-beams 13a on each of the second wall segments n2 can have the same structure, thus ensuring consistent compression resistance on both the front and rear sides. Furthermore, the sub-beams 13a on the first wall segment n1 can consist only of the upper arm beam 131 mentioned in the above embodiments. The upper arm beam 131 is positioned close to the top of the main body 11. In this case, the compression resistance of the sub-beams 13a is relatively weak, mainly because the vehicle 1000 typically has compression-resistant structures such as bumpers in the front-rear direction. When the vehicle 1000 is subjected to compression in the front-rear direction, the compression resistance is mainly achieved through its front and rear bumpers. Therefore, the compression resistance requirement for the sub-beams 13a on the second wall segment n2 is relatively weak. Thus, a relatively simple sub-beam 13a structure can be adopted, reducing the cost of the battery 100 and the vehicle 1000.

[0145] At this time, the sub-beams 13a are set on each second wall segment n2, which can strengthen the structural strength of each second wall segment n2 and improve the compression resistance of each second wall segment n2. In other words, the compression resistance of the vehicle 1000 is improved. Understandably, 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.

[0146] 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 disposed on the circumferential sidewall n. The first sub-beams 13a1 extend along a first direction F1 and are spaced apart from each other, and the second sub-beams 13a2 extend along a second direction F2 that intersects with the first direction F1 and are spaced apart from each other.

[0147] At this point, the sub-beam 13a located in the first wall segment n1 is designated as the first sub-beam 13a1, and the sub-beam 13a located in the second wall segment n2 is designated as the second sub-beam 13a2. The two first sub-beams 13a1 can enhance the compressive strength of the box body 10 in the lateral direction of the vehicle 1000, and the two second sub-beams 13a2 can enhance the compressive strength of the box body 10 in the longitudinal direction of the vehicle 1000. In this way, the lateral compressive strength of the vehicle 1000 can be comprehensively improved, thereby enhancing the safety performance of the vehicle 1000.

[0148] In some embodiments, continue to refer to Figure 6 The top of the side beam 13 has a mounting section 13a3.

[0149] The description of the mounting part 13a3 can be found above and will not be repeated here. By placing the mounting part 13a3 on top of the side beam 13, the box 10 of this embodiment can be obtained by adding the side beam 13 to the existing box 10 structure. This significantly reduces modification costs. Furthermore, since the side beam 13 does not define the receiving cavity s, the impact of the mounting part 13a3 on the sealing of the receiving cavity s does not need to be considered when setting the mounting part 13a3, making the setting of the mounting part 13a3 more flexible. Moreover, since the side beam 13 is located at the lateral edge of the box 10, placing the mounting part 13a3 on the side beam 13 provides a larger and more convenient operating space when installing the box 10 onto external devices.

[0150] In some embodiments, the mounting portion 13a3 includes at least one mounting hole k1 located on the top of the side beam 13.

[0151] The description of the mounting hole k1 can be found in the above description and will not be repeated here. The mounting hole k1 is located at the top of the side beam 13, which also has the beneficial effect of the mounting part 13a3 being located at the top of the side beam 13, and will not be repeated here.

[0152] In some embodiments, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 together define the top surface h of the box body 10.

[0153] The top surface h1 of the main body 11 refers to the outer surface of the main body 11 located at its top and facing away from the receiving cavity s. The top surface h2 of the lateral beam 13 refers to the outer surface of the lateral beam 13 located at its top. When the lateral beam 13 includes the upper arm beam 131 and the lower arm beam 132 in the above 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.

[0154] When the housing 10 includes both the main body 11 and the side beam 13 as described in the above embodiments, the top surface h of the housing 10 can be defined by the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. The top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can be coplanar. In this case, the contact area between the top surface h of the housing 10 and the external device is larger, which helps to improve the reliability of the connection between the housing 10 and the external device. At the same time, the top structure of the housing 10 is relatively flat and more aesthetically pleasing. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can also be non-coplanar.

[0155] Understandably, 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. This mounting portion 13a3 may be provided on a portion of the sub-beams 13a, or it may be provided on all sub-beams 13a. When the mounting portion 13a is provided on a portion of the sub-beams 13a, to ensure the uniformity of the stress on the mounting portion 13a3, mounting portions 13a3 are provided on all symmetrically arranged sub-beams 13a. The symmetrically arranged sub-beams 13a may include the two first sub-beams 13a1 in the above embodiment, or the two second sub-beams 13a2 in the above embodiment.

[0156] In some embodiments, please refer to Figure 6 and Figure 10 The outer wall of the housing 10 is provided with a wiring section 13a4, which is located below the top surface h of the housing 10 and forms a wiring space for wire harnesses to pass through.

[0157] The outer wall of the housing 10 is an outer surface opposite to the inner surface that defines the receiving cavity s within the housing 10. The wiring portion 13a4 is located below the top surface of the housing 10, that is, the wiring portion 13a4 is provided on the outer wall of the housing 10 located below the top surface h. The outer wall of the housing 10 located below its own top surface h includes a bottom surface and a side wall connecting the top surface h and the bottom surface.

[0158] When the housing 10 only includes the main body 11, the sidewall of the housing 10 is the circumferential sidewall n of the main body 11. When the housing 10 includes the main body 11 and the side beam 13, the sidewall of the housing 10 includes the circumferential sidewall n of the main body 11 that is not covered by the side beam 13 and the surface of the side beam 13 that is away from the main body 11.

[0159] The wiring section 13a4 is located outside the receiving cavity s and has a wiring space for the wire harness to pass through between the power supply connection cell and the electrical component. The specific form of the wiring space is not limited, as long as it has an inlet for the wire harness to enter and an outlet for the wire harness to exit, and the inlet and outlet can be the same opening. The wiring space can be a wiring hole or a wiring groove k2.

[0160] Specifically, a wiring section 13a4 can be provided on the circumferential outer wall of the enclosure 10, allowing the wire harness to be routed along the side of the enclosure 10, which is more convenient. Alternatively, a wiring section 13a4 can be provided on the bottom surface of the enclosure 10, allowing the wire harness to be routed along the bottom of the enclosure 10.

[0161] At this time, by forming a wiring section 13a4 on the outer wall of the housing 10, the wiring space formed by the wiring section 13a4 provides a space for the wiring harness to run, which can effectively protect the wiring harness and prevent the wiring harness from being squeezed and deformed when the vehicle 1000 is subjected to external pressure, thus avoiding unnecessary safety hazards.

[0162] In a further embodiment, reference continues to be made to... Figure 6 and Figure 10 The wiring section 13a4 is arranged on the side wall of the housing 10 adjacent to its own top surface h.

[0163] The sidewall is the outer surface of the enclosure 10 that connects its top surface h to its bottom surface (the surface opposite to the top surface h). The wiring section 13a4 may be provided only on a portion of the sidewalls of the enclosure 10, such as one or two sidewalls of the enclosure 10 in the first direction F1, or one or two sidewalls of the enclosure 10 in the second direction F2. Of course, the wiring section 13a4 may also be provided on all sidewalls of the enclosure 10.

[0164] At this time, the wiring section 13a4 is arranged on the side wall of the housing 10. Since the housing 10 has a large lateral operating space, it is more convenient to arrange the wiring harness.

[0165] In some embodiments, the wiring portion 13a4 is arranged in the housing 10 on two side walls that are adjacent to the top surface h and opposite to each other.

[0166] The two sidewalls of the housing 10 that are adjacent to and opposite to the top surface h include two opposite sidewalls in the first direction F1 and two opposite sidewalls in the second direction F2. In this case, the wiring section 13a4 can be arranged symmetrically opposite each other in the first direction F1 or oppositely in the second direction F2. The wiring harness can be routed simultaneously from both sides of the housing 10 in the first direction F1 or from both sides of the housing 10 in the second direction F2, achieving a symmetrical arrangement of the wiring harness. This makes the wiring harness arrangement more aesthetically pleasing and also contributes to the weight balance of the vehicle 1000.

[0167] Furthermore, the wiring section 13a4 is provided on the two side walls of the housing 10 in the second direction F2, that is, 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 power for the vehicle 1000 to move forward) on the vehicle 1000 are mainly located on the front or rear side, the wiring harness mainly connects the battery 100 and the electric drive system along the front and rear directions of the vehicle 1000. This arrangement of the wiring section 13a4 makes the wiring harness routing more convenient.

[0168] In a specific embodiment, reference is made to Figure 6 and Figure 10 The wiring section 13a4 includes a wiring groove k2 recessed into the outer wall of the housing 10 toward the receiving cavity s.

[0169] Understandably, the cable tray k2 is recessed towards the receiving cavity s, forming a cable routing space with one side open, the opening opposite the bottom of the cable tray k2. While the cable tray k2 is recessed towards the receiving cavity s, it can also have an inlet and an outlet. Specifically, the inlet of the cable tray k2 can be an opening at one end along its extension direction, and the outlet of the cable tray k2 can be an opening at the other end along its extension direction.

[0170] When the cable tray k2 is located on the side wall of the housing 10 in the second direction F2, the cable tray k2 can extend along the first direction F1. When the cable tray k2 is located on the side wall of the housing 10 in the first direction F1, the cable tray k2 can extend along the second direction F2.

[0171] At this point, since the wiring trough k2 has an open opening, the open design makes it easier to thread the wire harness. Moreover, the wiring trough k2 formed by the recess is constructed as the wiring section 13a4, eliminating the need for additional structures to form wiring space, making the structure of the housing 10 simpler and the cost lower.

[0172] Of course, in other embodiments, the wiring section 13a4 may also be a structure with wiring holes additionally provided on the outer wall of the housing 10, such as a wiring rod with wiring holes.

[0173] In some embodiments, refer to Figure 6 and Figure 10 The side beam 13 forms the wiring section 13a4.

[0174] Specifically, when the wiring section 13a4 is a wiring groove k2, the side beam 13 can be composed of an upper arm beam 131 and a lower arm beam 132 as described 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 side beam 13 can be recessed away from the outer surface of the main body 11 to form the wiring groove k2.

[0175] When the wiring section 13a4 is a wiring hole, and the lateral beam 13 is a hollow beam with both ends extending along its extension direction, the internal space of the lateral beam 13 can be configured to form a wiring hole. Alternatively, the lateral beam 13 includes the upper arm beam 131, the lower arm beam 132, and the middle beam (not shown) in the above embodiments, with the wiring hole being enclosed by the middle beam, the upper arm beam 131, and the lower wall beam.

[0176] At this time, the wiring section 13a4 forms a side beam 13, which means that the side beam 13 has wiring space. The wiring space can reduce the weight of the side beam 13 and realize wiring at the same time, achieving two goals at once.

[0177] In one specific embodiment, the upper arm beam 131 and the lower arm beam 132 together form a wiring section 13a4 with 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 wiring section 13a4 has a simple structure and achieves two goals at once.

[0178] Figure 11 This is a partial structural schematic diagram of the battery 100 in some other embodiments of this application. Figure 12 for Figure 11 An exploded view of the side view of the structure shown. Figure 13 for Figure 11 Side view of the structure described. Figure 14 for Figure 12 An enlarged view of point D in the structure shown. Figure 15 for Figure 11 The diagram shows an application scenario of the structure. Figure 16 for Figure 14 Side view of the structure shown.

[0179] In some embodiments, please refer to Figure 11 The housing 10 also includes a sealing element 12, which is located on the top of the housing 10 and is used for sealing connection with external devices.

[0180] The seal 12 is a component that prevents fluid or solid particles from leaking between adjacent mating surfaces. The seal 12 is located on the top of the housing 10 and divides the top of the housing 10 into an outer area surrounding the seal 12 and an inner area enclosed by the seal 12. The seal 12 seals the connection between the top of the housing 10 and two surfaces opposite to the external device, and forms a contact interface with these two surfaces. This prevents fluid or solid particles in the outer area surrounding the seal 12 from entering the inner area enclosed by the seal 12 through the contact interface between itself and the two surfaces, thereby achieving a sealing effect.

[0181] The seal 12 can be a sealing ring or a sealing gasket. Specifically, the seal 12 can be made of materials such as rubber or silicone. Specifically, the seal 12 can be an O-ring seal, a square seal, or a non-circular seal. The specific shape of the seal 12 can be adapted to the shape of the top of the housing 10 and the two opposite surfaces of the external device. For example, when the top of the housing 10 and the two opposite surfaces of the external device are square, the seal 12 can be a square seal.

[0182] At this time, the casing 10 of the battery 100 is sealed to the external device through the sealing element 12, which is reliable and low cost.

[0183] Understandably, the battery 100's casing 10 is sealed to the external device through the sealing member 12, and is also fixedly connected to the external device through the mounting part 13a3, and at this time, the top surface h of the casing 10 is in contact with the external device.

[0184] Taking the vehicle body 200 of the vehicle 1000 as an example, the battery 100 can be installed at the bottom of the vehicle body 200 and sealed to the vehicle body 200 through the seal 12 on the sealing area hc. At this time, the inner area of ​​the seal 12 is the inside of the vehicle body 200 and the outer area is the outside of the vehicle body 200. Fluids or solid particles outside the vehicle body 200 cannot leak into the inside of the vehicle body 200. For example, stones or liquids splashed during the driving of the vehicle 1000 cannot hit the inside of the vehicle body 200, thereby achieving the sealing and structural reliability of the inside of the vehicle body 200.

[0185] In some embodiments, please refer to Figure 7 and Figure 11 The top of the housing 10, away from the receiving cavity s, has a mounting position 141b. The battery 100 is mounted to an external device via the top of the housing 10, and the mounting position 141b forms part of the structure of the external device.

[0186] Mounting position 141b is a mounting area formed by constructing a partial area on the top of the housing 10 for mounting a certain structure (hereinafter referred to as a mounting component). This mounting component can be a part of the structure of an external device, and mounting position 141b can be a mounting clip, mounting hole, or other structure with a connecting function. Taking the body 200 of the vehicle 1000 as an example, this mounting position 141b can be used to mount the seat 300 of the vehicle 1000, or a control lever, etc. The seat 300 or control lever, etc., are fixedly connected to the mounting position 141b on the top of the housing 10 through mounting clips or mounting holes.

[0187] Specifically, the mounting component installed on mounting position 141b can be a partial structure of an external device. After the mounting position 141b, used to install this partial structure, is connected to the external device at the top of the housing 10, it also forms a partial structure of the external device. At this point, the battery 100 is mounted on the external device through the top of the housing 10. After the mounting position 141b on the top of the battery 100 forms a partial structure of the external device, connecting the mounting component to the housing 10 of the battery 100 achieves the connection with the external device.

[0188] In this way, the battery 100 and the external device are partially integrated, so that part of the structure of the battery 100 housing 10 is also part of the structure of the external device, thereby avoiding the separation of the battery 100 and the external device.

[0189] In other embodiments, the mounting element 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 simultaneously achieve a fixed connection with the battery 100 and the external device.

[0190] In a specific embodiment, such as Figure 14 and Figure 15 Taking the vehicle body 200 of the vehicle 1000 as an example, and the mounting position 141b for mounting the seat 300, the mounting position 141b is constructed on the top of the battery box 10, so that the mounting 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 separate setting of the battery 100 and the vehicle body 200, and making the vehicle 1000 simpler in structure, smaller in size and more compact.

[0191] Understandably, the fixed connection of the housing 10, the body 200 and the seat 300 can ensure that all structures are vertically connected to the top of the housing 10, reducing the installation space and installation stress in other directions of the housing 10, reducing the stress on the lateral and bottom structures of the battery 100 housing 10, and improving the structural stability of the vehicle 1000.

[0192] In some embodiments, please refer to Figure 7 Mounting position 141b includes mounting holes constructed on the top of housing 10.

[0193] The mounting hole is a through hole that penetrates the mounting position 141b in the vertical direction. When mounting the seat 300, etc., to the mounting position 141b, a fastener needs to be installed. The mounting hole can be a smooth through hole (such as when the fastener is a rivet), a threaded through hole (such as when the fastener is a screw), or a through hole of other types (such as a hexagonal hole, a square hole, an oblong hole, etc.). The specific form of the fixing hole 11c3 depends on the specific form of the fastener and the specific setting method, and will not be described in detail here.

[0194] The number of mounting holes is the same as the number of fasteners. Each mounting hole is equipped with a fastener. The corresponding mounting part is installed and positioned in the mounting hole by the fastener, so that the mounting part is fixed to the housing 10 of the battery 100, and the mounting part is fixedly connected to the external device.

[0195] In other embodiments, the mounting position 141b may also include other structures constructed on the top of the housing 10, such as snaps, spring locks, etc., which are not specifically limited.

[0196] In some embodiments, please refer to Figures 4 to 7 ,and Figure 11 The housing 10 includes a main body 11 and a mounting beam 141. The main body 11 encloses and forms a receiving cavity s, and the top of the main body forms at least a portion of the top of the housing 10. The mounting beam 141 is located on the top of the main body 11 and has a mounting position 141b on its side opposite to the main body 11.

[0197] The main body 11 can be a one-piece structure or assembled from multiple parts. Its specific configuration has been explained in detail above and will not be repeated here.

[0198] The top of the housing 10, away from the receiving cavity s, has a top surface h. The mounting position 141b is connected to the top surface h. The mounting beam 141 is a structure with a certain load-bearing capacity located on one side of the top of the main body 11, used to share the force exerted on the top of the housing 10 by the mounting components. For example... Figure 15 and 16 As shown, when the mounting component is seat 300, the operator sitting on seat 300 will apply pressure, which will first be applied to the mounting beam 141 and then to the top of the housing 10.

[0199] The mounting beam 141 can be directly set on the surface of the top surface h or on a recessed or protruding part formed on the top surface h. 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 component, thereby realizing the connection between the mounting component and the top of the housing 10.

[0200] The form and extension direction of the load-bearing structure are set according to the size, weight and specific structure of the mounting parts to be installed on the mounting position 141b, and are not limited in specific terms. The load-bearing capacity of the battery box 10 is improved by sharing the force on the top of the main body 11 through the mounting beam 141.

[0201] In some embodiments, the mounting beam 141 is fixedly connected to the body 11 or integrally formed.

[0202] The mounting beam 141 and the main body 11 can be fixedly connected by means of fastening, snap-fit ​​structure, welding, bonding, or hot-melt connection. Of course, the mounting beam 141 and the main body 11 can also be integrally formed by means of injection molding, die casting, forging, cold pressing, or hot pressing.

[0203] 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 both made of metal, they can be welded or bonded together. When the mounting beam 141 and the main body 11 are both made of plastic, they can be bonded together.

[0204] 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 relatively easy, which can reduce the process cost of the box 10.

[0205] When the mounting beam 141 is integrally formed with the main body 11, the assembly of the box body 10, external devices and mounting parts is convenient.

[0206] In other embodiments, the main body 11 is connected to the portion other than the mounting beam 141, and the connection method can be either integral molding or fixed connection. Specific details are not limited.

[0207] In some embodiments, please refer to Figure 7 and Figure 11 The mounting beam 141 includes at least one protrusion 141a, each protrusion 141a protruding from the top of the main body 11 in a direction away from the receiving 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.

[0208] The protrusion 141a is the load-bearing structure included in the mounting beam 141 mentioned above. It protrudes from the plane containing the top surface h of the housing 10 in a direction away from the receiving cavity s. The protrusion 141a itself has a certain height, thus protruding from the top surface h of the housing 10. The mounting position 141b is formed on the side of all protrusions 141a away from the main body 11. When the mounting component is installed on the mounting position 141b, it directly contacts the structure of the protrusion 141a, but does not directly contact the top surface h. Thus, the force on the top of the housing 10 is distributed through the protrusion 141a, increasing the load-bearing capacity of the top of the housing 10.

[0209] Each protrusion 141a can form 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 they form a weight-reducing channel 141a1. The weight-reducing channel 141a1 can be formed by hollowing out the inside of the protrusion 141a or by drilling, slotting, etc., to achieve a lightweight design of the box 10.

[0210] In one specific embodiment, each protrusion 141a has a weight-reducing channel 141a1 extending through it along its own extension direction. The weight-reducing channel 141a1 reduces the weight of each protrusion 141a, thereby reducing the overall weight of the housing 10 and lowering the cost. Each through-type weight-reducing channel 141a1 can form a hidden channel, which can also be used for concealed wiring and other operations in other embodiments.

[0211] 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.

[0212] The direction referred to as "the same direction" can be either the first direction F1 or the second direction F2 mentioned above, or it can be a direction that is coplanar with and intersects the first direction F1 and the second direction F2. The specific direction is not limited.

[0213] The spacing between all protrusions 141a means that a predetermined interval is maintained between every two adjacent protrusions 141a in the direction intersecting with the extension direction of the protrusions 141a. This predetermined interval creates a buffer space between every two adjacent protrusions 141a, preventing external forces acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the multiple spaced protrusions 141a can form a sufficiently large support area and fixing position to achieve large-area support for the mounting component and can be used for mounting components of different volumes and sizes.

[0214] All protrusions 141a are arranged parallel to each other in the same direction, so that the buffer space extends in the same direction as the protrusions 141a. In practical applications, buffering can be achieved at any position in the extension direction of the mounting beam 141.

[0215] The set interval between any two adjacent protrusions 141a may be equal or unequal. Understandably, in order to ensure uniform support for the mounting component, the set interval between any two adjacent protrusions 141a is equal.

[0216] In some embodiments, all the protrusions 141a on the side facing away from the body 11 are located on the same plane.

[0217] All protrusions 141a are arranged to protrude in the same direction and all protrusions 141a have the same protrusion height, so that the side of all protrusions 141a away from the mounting cavity forms a flat plane in a certain direction, such as a flat plane on a horizontal plane. The mounting component is placed on the flat plane for installation, making the installation more stable and simple, and enabling a firm connection between the mounting component and the mounting beam 141.

[0218] In one specific embodiment, the protrusion 141a may be a quadrangular prism structure, and the same side of all the protrusions 141a is located on the same plane and together defines a mounting position 141b for mounting the mounting component, so as to place the mounting component stably on the mounting beam 141.

[0219] In some embodiments, please refer to Figure 4 , Figure 7 and Figure 11 The housing 10 also includes a side impact reinforcement beam 14, which is disposed on the top of the main body 11 and extends from the middle of the top of the main body 11 to the opposite outer edges of the top of the main body 11.

[0220] The side impact reinforcement beam 14 refers to a beam structure installed on the top of the main body 11 to strengthen its strength. Understandably, the side impact reinforcement beam 14 is located on the outside of the main body 11. Specifically, the main body 11 and the side impact reinforcement beam 14 are integrally connected, or they can be assembled together. Integral connection includes, but is not limited to, welding, integral molding, and fusion. Assembly connection includes, but is not limited to, snap-fit, threaded connection to the high-pressure chamber s2, etc.

[0221] The side impact reinforcement beam 14 can extend from the middle of the top of the main body 11 to the opposite outer edges of the top of the main body 11 in the first direction F1. In this case, the side impact reinforcement beam 14 can enhance the side impact resistance of the enclosure 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 opposite outer edges of the top of the main body 11 in the second direction F2. In this case, the side impact reinforcement beam 14 can enhance the side impact resistance of the enclosure 10 in the second direction F2.

[0222] The side impact reinforcement beam 14 can extend from the middle of the top of the main body 11 along two collinear directions to the opposite outer edges of the top of the main body 11, or it can extend from the middle of the top of the main body 11 along two intersecting directions to 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 to the opposite outer edges along two collinear directions, the side impact reinforcement beam 14 is implemented by a straight beam, which simplifies the structure.

[0223] The side impact reinforcement beam 14 can extend to the outer edges of both sides, or to the area between the outer edges of both sides and the middle, or to the area outside the outer edges of both sides. In other words, the specific extension length of the side impact reinforcement beam 14 is not limited, as long as it extends from the middle of the top of the main body 11 toward the opposite outer edges of the top of the main body 11.

[0224] When the battery 100 is applied to the vehicle 1000 and the top structure of the box 10 is the chassis of the vehicle 1000, since the vehicle 1000 has poor side impact protection capability in the left and right directions, the side impact reinforcement beam 14 can be designed to extend from the middle of the top of the main body 11 toward the outer edges of 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 impact protection capability of the vehicle 1000 in the left and right directions and improve the safety performance of the vehicle 1000.

[0225] At this time, a side impact reinforcement beam 14 is provided on the top of the main body 11 of the box 10, which can improve the side impact resistance of the box 10, thereby improving the side impact resistance of the vehicle 1000 loaded with the battery 100 composed of the box 10, and helping to ensure the safety performance of the battery 100 and the vehicle 1000.

[0226] When the main body 11 includes the frame 11b and the support member 11a, the side impact reinforcement beam 14 is at least provided on the top of the support member 11a. At this time, since the top of the support member 11a forms at least a part of the top of the main body 11, the support member 11a has sufficient space for the installation of the side impact reinforcement beam 14.

[0227] In some embodiments, the side impact reinforcement beam 14 extends to connect with the top of the frame 11b.

[0228] At this time, the top of the frame 11b also forms part of the top of the main body 11. 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 between the frame 11b and the carrier 11a can also be strengthened by the side impact reinforcement beam 14, which can enhance the reliability of the connection between the frame 11b and the carrier 11a.

[0229] In some embodiments, the number of side impact reinforcement beams 14 is at least one, and all side impact reinforcement beams 14 extend in the same direction and are spaced apart from each other.

[0230] The direction referred to as "the same direction" can be either the first direction F1 or the second direction F2 mentioned above, or it can be a direction that is coplanar with and intersects the first direction F1 and the second direction F2. The specific direction is not limited.

[0231] All side impact reinforcement beams 14 extend in the same direction, and each side impact reinforcement beam 14 can enhance the side impact resistance of the enclosure 10 in the extending direction, thereby strengthening the side impact resistance of the enclosure 10 in that extending direction. Understandably, the side impact reinforcement beams 14 are arranged at intervals along directions intersecting this "same direction", which can strengthen the strength of the enclosure 10 at multiple locations, making the structural strength and side impact resistance of the enclosure 10 more uniform.

[0232] In some embodiments, at least one of the side impact reinforcement beams 14 is configured as a mounting beam 141, and a mounting position 141b is configured on the side of the mounting beam 141 facing away from the main body 11.

[0233] For details regarding the mounting beam 141 and mounting position 141b, please refer to the above description, which will not be repeated here. When the side impact reinforcement beam 14 includes one beam, it serves as the mounting beam 141. When the side impact reinforcement beam 14 includes at least two beams, each beam can partially serve as the mounting beam 141. Specifically, when the side impact reinforcement beam 14 includes at least two beams, the side impact reinforcement beam 14 closest to the front of the vehicle 1000 can serve as the mounting beam 141 for mounting the seat 300 (the seat 300 can be the seat 300 in the driver's cab).

[0234] At this point, using at least one of the side impact reinforcement beams 14 as the mounting beam 141 not only provides the effect of preventing side impacts, but also allows for the installation of other mounting components, thus serving a dual purpose.

[0235] In some embodiments, the side impact reinforcement beam 14 includes at least one protrusion 141a, each protrusion 141a protruding from the top of the body 11 in a direction away from the receiving cavity s, and each protrusion 141a together with the body 11 forms a weight reduction channel 141a1.

[0236] The protrusion 141a of the side impact reinforcement beam 14 is the same as the protrusion 141a mentioned in the above embodiment when describing the structure of the mounting beam 141. For details, please refer to the above description. The protrusion 141a protrudes from the plane of the top surface h1 of the main body 11 in a direction away from the receiving cavity s. The protrusion 141a itself has a certain height, thus protruding from the top surface h1 of the main body 11.

[0237] Each protrusion 141a can form 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 they form a weight-reducing channel 141a1. The weight-reducing channel 141a1 can be formed by hollowing out the inside of the protrusion 141a or by drilling, slotting, etc., to achieve a lightweight design of the box 10.

[0238] In one specific embodiment, each protrusion 141a has a weight-reducing channel 141a1 extending through it along its own extension direction. The weight-reducing channel 141a1 reduces the weight of each protrusion 141a, thereby reducing the overall weight of the housing 10 and lowering the cost. Each through-type weight-reducing channel 141a1 can form a hidden channel, which can also be used for concealed wiring and other operations in other embodiments.

[0239] In some embodiments, please refer to Figure 7 All the protrusions 141a extend in the same direction and are spaced apart from each other.

[0240] The spacing between all protrusions 141a means that a predetermined interval is maintained between every two adjacent protrusions 141a in the direction intersecting with the extension direction of the protrusions 141a. This predetermined interval creates a buffer space between every two adjacent protrusions 141a, preventing external forces acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the multiple spaced protrusions 141a can form a sufficiently large support area and fixing position to achieve large-area support for the mounting component and can be used for mounting components of different volumes and sizes.

[0241] All protrusions 141a are arranged parallel to each other in the same direction, so that the buffer space extends in the same direction as the protrusions 141a. In practical applications, buffering can be achieved at any position in the extension direction of the side impact reinforcing beam 14.

[0242] The set interval between any two adjacent protrusions 141a can be equal or unequal. Understandably, when the side impact reinforcement beam 14 is used as the mounting beam 141, in order to ensure uniform support for the mounting component, the set interval between any two adjacent protrusions 141a is equal.

[0243] In some embodiments, all the protrusions 141a on the side facing away from the body 11 are located on the same plane.

[0244] One side of all the protrusions 141a is located on the top surface h1 of the main body 11. 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 away from the mounting cavity forms a flat plane in a certain direction, such as a flat plane on a horizontal plane, so as to achieve a firm connection between the mounting component and the mounting beam 141.

[0245] In one specific embodiment, the protrusion 141a may be a quadrangular prism structure, and the same side of all the protrusions 141a is located on the same plane and together defines a mounting position 141b for mounting the mounting component, so as to place the mounting component stably on the mounting beam 141.

[0246] In some embodiments, please refer to Figure 10 The housing 10 has a battery chamber s1 and a high-voltage chamber s2 that are independently arranged. 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.

[0247] The high-voltage box is a crucial safety barrier for the 100 battery packs. It is equipped with a high-voltage control system, which is mainly used for: connecting or disconnecting the high-voltage circuit according to the vehicle's electronic control requirements; providing current and leakage detection terminals; achieving controllable load disconnection when the external current of the 100 battery packs is too high; disconnecting the high-voltage circuit when a short circuit occurs in the external wiring of the 100 battery packs to prevent the 100 battery packs from catching fire; and conveniently disconnecting the high-voltage circuit when maintaining the 100 battery packs.

[0248] The independent arrangement of battery chamber s1 and high-voltage chamber s2 means that battery chamber s1 and high-voltage chamber s2 are sealed to each other. To achieve this independent arrangement, battery chamber s1 and high-voltage chamber s2 can be formed by two separate components. For example, the interior of the housing 10 can have independent first and second components, with the first component forming battery chamber s1 and the second component forming high-voltage chamber s2. Alternatively, a partition can be installed inside the housing 10 to separate the accommodating cavities s formed within the housing 10 into independent battery chamber s1 and high-voltage chamber s2. Alternatively, all the accommodating cavities s formed inside the housing 10 can be used as battery chamber s1, and a high-voltage chamber 15 can be constructed outside the housing 10 to form high-voltage chamber s2, thus achieving the independence of battery chamber s1 and high-voltage chamber s2.

[0249] Battery chamber s1 is used to accommodate battery cell 20, and high voltage chamber s2 is used to accommodate high voltage box. When battery chamber s1 and high voltage chamber s2 are set independently, if the high temperature gas leaked by the battery cell 20 in battery chamber s1 due to thermal failure will not enter the high voltage box, and thus will not cause thermal damage to the high voltage control system in the high voltage box. This can ensure the normal control function of the high voltage control system and improve the safety performance of battery 100.

[0250] In some embodiments, refer to Figures 11 to 13 The housing 10 also includes a high-voltage chamber 15. A battery cavity s1 is formed inside the main body 11. The high-voltage chamber 15 is located outside the main body 11 and is either enclosed by itself or together with the main body 11 to form a high-voltage cavity s2.

[0251] The high-voltage chamber 15 can be a shell structure 22, with a hollow interior forming the high-voltage chamber 15 for housing the high-voltage box. The high-voltage chamber 15 is located outside the main body 11, and the battery cavity s1 is formed by the main body 11 (at this time, the battery cavity s1 is equivalent to the receiving cavity s), thus realizing the independent setting of the high-voltage cavity s2 and the battery cavity s1.

[0252] When the high-pressure chamber 15 and the main body 11 together form the high-pressure cavity s2, the high-pressure chamber 15 has an opening and is installed on the main body 11 through this opening. When the high-pressure chamber 15 encloses itself to form the high-pressure cavity s2, there is only an installation relationship between it and the main body 11.

[0253] At this time, the high-pressure chamber s2 is defined by the high-pressure chamber 15 located outside the main body 11, and the receiving chamber s formed by the main body 11 can be used to receive the battery chamber s1 to accommodate the battery cell 20, thereby increasing the capacity of the battery 100.

[0254] In some embodiments, reference is made to Figures 11 to 12 The high-pressure chamber 15 is protruding and set on the top of the main body 11.

[0255] The high-voltage compartment 15 is protruding from the top of the main body 11, meaning that the high-voltage compartment 15 is located outside the main body 11 and 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, since the high-voltage compartment 15 is located on the top of the main body 11, it is not exposed outside the vehicle 1000 and can be protected from external impacts (such as stones splashed during the driving of the vehicle 1000), making the high-voltage compartment 15 safer.

[0256] Understandably, 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, and the high-pressure chamber 15 is disposed on the top of the support member 11a, forming a high-pressure cavity s2 by itself or together with the support member 11a. In this case, since the support member 11a constitutes most of the top area of ​​the main body 11, placing the high-pressure chamber 15 on the top of the support member 11a provides more space for its installation and makes the installation more stable.

[0257] Of course, when the top of the frame 11b is also constructed as 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. The specific configuration can be determined according to the installation method of the frame 11b and the carrier 11a.

[0258] In some embodiments, reference is made to Figures 11 to 13 The high-pressure chamber 15 is located near the top outer edge of the main body 11.

[0259] The top outer edge of the main body 11 includes: one outer edge of the top of the main body 11 in the direction in front of the vehicle 1000, one outer edge of the top of the main body 11 in the direction behind the vehicle 1000, one outer edge of the top of the main body 11 in the direction to the left of the vehicle 1000, and one outer edge of the top of the main body 11 in the direction to the right of the vehicle 1000.

[0260] In one application example, the high-pressure chamber 15 is located near the top of the main body 11 on one outer edge in the direction of the rear 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 in the passenger space behind the driver's space of the vehicle 1000. In particular, it can be arranged under the seat 300 of the passenger space, so as not to occupy the activity space of the vehicle 1000.

[0261] In some embodiments, refer to Figure 4 , Figure 6 , Figures 11 to 13 The high-pressure chamber 15 and the side impact reinforcement beam 14 are arranged sequentially in the first direction F1, and the side impact reinforcement beam 14 extends along the second direction F2, which intersects with the first direction F1.

[0262] When the housing 10 includes the side impact reinforcement beam 14, the high-pressure chamber 15 and the side impact reinforcement beam 14 can both be located on the top of the main body 11.

[0263] 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 along the second direction F2, which intersects with the first direction F1, without interfering with the high-pressure chamber 15. The structural arrangement of the high-pressure chamber 15 and the side impact reinforcement beams 14 is relatively reasonable, and the utilization rate of the top space of the main body 11 is high.

[0264] In 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 located on the top of the main body 11 and forms a high-pressure cavity s2 that is open away from the main body 11. The chamber cover 15a is detachably covered on the open side of the high-pressure cavity s2.

[0265] The compartment 15b and the main body 11 can be connected by welding, fusion, bonding, fastening, etc. The compartment 15b can be made of any plastic. The compartment cover 15a and the compartment 15b can be detachably connected by fasteners or by snap-fit; the specific form is not limited.

[0266] At this time, the high-pressure chamber s2 is formed by the chamber box 15b, and the high-pressure chamber s2 is sealed by the chamber cover 15a. The chamber cover 15a and the chamber box 15b are detachably connected, which facilitates the installation and maintenance of the high-pressure box.

[0267] Figure 17 This is a partial structural schematic diagram of the battery 100 in some other embodiments of this application. Figure 18 for Figure 17 The side view of the structure shown. Figure 19 for Figure 18 An exploded view of the structure described above. Figure 20 for Figure 18The cross-sectional view at EE in the structure shown. Figure 21 for Figure 17 The top view of the structure shown.

[0268] In some embodiments, please refer to Figures 17 to 21 The housing 10 also includes a central channel beam 16, which extends along the first direction F1 and is disposed on the top of the main body 11. It is equidistant from the outer edges of the top of the main body 11 on both sides in the second direction F2, which intersects with the first direction F1. The central channel beam 16 has a wiring channel 16a for wire harnesses to pass through.

[0269] In a conventional vehicle 1000, a central channel beam 16 is typically installed on the chassis of the vehicle 1000 body 200. The central channel beam 16 is a beam structure on the vehicle 1000 body 200 that extends from the front chassis to the rear chassis. It is a major structural component that serves as the collision transmission path for the body 200 and ensures the rigidity of the body 200's floor plate. The central channel beam 16 is located in the middle area of ​​the vehicle 1000 chassis and extends from the front chassis to the rear chassis along the longitudinal direction of the vehicle 1000.

[0270] 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 10. Specifically, the central channel beam 16 extends along the first direction F1 (corresponding to the front-rear direction of the vehicle body 200) and is equidistant from the outer edges on both sides of the top of the main body 11 in the second direction F2 (corresponding to the left-right direction of the vehicle body 200), so as to be arranged in the middle region of the top of the main body 11.

[0271] 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 inside the central channel beam 16 is used to form a wiring channel 16a for the wire harness to pass through. This not only reduces weight but also allows for more flexible and safer wiring harness arrangement.

[0272] The central channel beam 16 can be a sheet metal component integrally formed by stamping, die casting, or other methods, or it can be a beam structure formed by welding, fusion, or fastening multiple sheet metal plates, as long as it can form a wiring channel 16a. The wiring channel 16a can be located inside the central channel beam 16 (such as a hole inside the central channel beam 16) or outside the central channel beam 16 (such as a recessed channel outside the central channel beam 16). The central channel beam 16 can form the wiring channel 16a together with the main body 11, or it can form the wiring channel 16a by itself. The central channel beam 16 and the main body 11 can be connected to form a whole by welding, fusion, fastening, or other methods.

[0273] The cable routing channels 16a provided by 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 according to requirements. There are no specific limitations, as long as cable routing can be achieved. The central channel beam 16 can be equipped with multiple independent cable routing channels 16a to achieve classified cabling of various types of wire harnesses, which facilitates installation and maintenance.

[0274] At this point, when the top structure of the housing 10 serves as the chassis of the vehicle body 200 (the chassis being the floor of the body 200), there is no need to additionally install the central channel beam 16, resulting in higher assembly efficiency for the body 200. Simultaneously, utilizing the hollow structure formed inside the central channel beam 16 creates a wiring channel 16a for the wire harness, which not only reduces weight but also allows for more flexible wiring harness arrangement.

[0275] In some embodiments, please refer to Figure 20 The central channel beam 16 includes a beam seat 161, which is located on the top of the main body 11 and has a wire groove 16a1 that serves as a wire routing channel 16a. The wire groove 16a1 is recessed toward the receiving cavity s.

[0276] The beam seat 161 is directly mounted on the main body 11 and can be fixed to the main body 11 by welding, fusion, fastening or other methods. The beam seat 161 forms a wire passage groove 16a1, which is recessed toward the receiving cavity s. That is to say, the wire passage groove 16a1 has a slot facing away from the receiving cavity s, which facilitates the threading of wire harnesses.

[0277] The wire passage groove 16a1 can be a continuous groove structure formed by recessing on the side surface of the beam seat 161 away from the receiving cavity s, or it can be a plurality of wire passage portions with grooves facing the cavity that are constructed on the side surface of the beam seat 161 away from the receiving cavity s. Each wire passage portion is arranged at intervals along a set direction, and the grooves of all the wire passage portions together form the wire passage groove 16a1 of the beam seat 161.

[0278] At this time, the beam seat 161 forms a wire passage groove 16a1 that is recessed towards the receiving cavity s, which facilitates the installation of the wire harness.

[0279] In some embodiments, please refer to Figure 20 There are multiple wire passage slots 16a1, all of which extend in the same direction and are spaced apart from each other.

[0280] Multiple wire passage slots 16a1 are provided, and the multiple wire passage slots 16a1 can extend along the same direction (such as the first direction F1) and be spaced apart. Each wire passage slot 16a1 can accommodate a type of wire harness (the wire harness can be classified according to the different objects connected to the wire harness, such as the wire harness connected to the air conditioner, the wire harness connected to the vehicle lights, the wire harness connected to the power drive system, etc.).

[0281] This allows for the independent arrangement of different types of wire harnesses, making wire harness installation and maintenance more convenient.

[0282] In some embodiments, the wire channel 16a1 is configured to engage with the wire harness passing through it.

[0283] To achieve the clamping of the wire harness in the wire passage 16a1, the opening size of the wire passage 16a1 can be approximately equal to or an interference fit with the diameter of the wire harness to be inserted, thus achieving the clamping connection. Alternatively, a clamping component can be designed into the opening of the wire passage 16a1. One end of the clamping component is rotatably connected to one side of the opening of the wire passage 16a1, and the other end is detachably clamped to the other side of the opening of the wire passage 16a1. After the wire harness is placed in the wire passage 16a1, the clamping component is used to clamp the wire harness into the opening of the wire passage 16a1.

[0284] This avoids noise caused by wire harness shaking, and also prevents the wire harness from being damaged due to it coming off the wire tray 16a1.

[0285] In some embodiments, please refer to Figure 20 The central channel beam 16 also includes a beam cover 162, which is detachably fitted onto the opening side of the cable tray 16a1.

[0286] The open side of the cable tray 16a1 is the side where the slot of the cable tray 16a1 is located. The beam cover 162 is detachably fitted onto the open side of the cable tray 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 can be detachably snapped together, or the beam cover 162 and the beam seat 161 can be detachably connected by fasteners (such as bolts). The method of detachably connecting the beam cover 162 and the beam seat 161 can adopt conventional settings in the art, and will not be limited or described in detail here.

[0287] At this time, by covering the opening of the wire groove 16a1 with the beam cover 162, external dust and moisture can be prevented from entering the wire groove 16a1 and corroding the wire harness. At the same time, the wire harness can be protected from external pressure and damage, which can improve the safety of the battery 100.

[0288] In some embodiments, the high-voltage chamber s2 is connected to the wiring channel 16a.

[0289] Understandably, 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 device. Therefore, the wiring harness passes through the high-voltage chamber s2 and the wiring channel 16a.

[0290] The connection between the high-voltage chamber S2 and the wiring channel 16a means that the wire harness exiting the high-voltage chamber S2 can enter the wiring channel 16a. Specifically, the high-voltage chamber S2 can have a wiring opening opposite the entrance of the wiring channel 16a. In this case, there are no obstacles between the wiring opening and the entrance of the wiring channel 16a, and the wire harness exiting through the wiring opening can directly enter the entrance of the wiring channel 16a without needing to turn. Alternatively, the high-voltage chamber S2 can have a wiring opening that is not opposite to the entrance of the wiring channel 16a but is spatially connected. In this case, there are obstacles between the wiring opening and the entrance of the wiring channel 16a (the obstacles can be formed by the central channel beam 16 or other structures). The wire harness exiting through the wiring opening needs to turn around the obstacles before entering the wiring channel 16a through the entrance.

[0291] At this time, the high-voltage chamber s2 is connected to the wiring channel 16a, which allows the wiring harnesses coming out of the high-voltage chamber s2 to be arranged through the wiring channel 16a.

[0292] In some embodiments, please refer to Figure 17 and Figure 21 The central channel beam 16 and the high-pressure chamber 15 are arranged adjacent to each other along the first direction F1.

[0293] The central tunnel beam 16 typically extends from the front chassis of the vehicle body 200 to the rear chassis of the vehicle body 200. The high-pressure compartment 15 is located on one side of the central tunnel beam 16 in the first direction F1. The high-pressure compartment 15 can be arranged in front of or behind the central tunnel beam 16. Specifically, the high-pressure compartment 15 can be arranged behind the central tunnel beam 16, corresponding 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 arrangement of the high-pressure compartment 15 can be achieved by hiding it in the space under the seats 300, so as to make higher space utilization in the passenger compartment of the vehicle 1000.

[0294] In some embodiments, please refer to Figure 11 The top surface h of the housing 10 has a first region ha and a second region hb. The second region hb surrounds the first region ha. The second region hb has multiple mounting parts 13a3, and the battery 100 is mounted to an external device through the mounting parts 13a3.

[0295] The formation of the first region ha and the second region hb can be achieved through other structural divisions, such as by providing a seal 12 on the top of the housing 10 and dividing the top surface h of the housing 10 into a second region hb located on the periphery of the seal 12 and a first region ha located on the inner periphery of the seal 12. When the battery 100 is installed on an external device via the mounting part 13a3, the first region ha and the second region hb are independent of each other.

[0296] The first region ha and the second region hb can also be automatically partitioned on the top surface h. In this case, there are no other structural gaps between the first region ha and the second region hb. When the battery 100 is installed on an external device through the mounting part 13a3, the first region ha and the second region hb can also be connected to each other.

[0297] Furthermore, the area of ​​the first region ha and the area of ​​the second region hb are not limited, and the first region ha and the second region hb can be flat surfaces or uneven surfaces, and their specific structures are not limited.

[0298] In one specific embodiment, such as the external device being the body 200 of a vehicle 1000, the mounting part 13a3 is constructed in the second region hb, so that the box 10 is connected to the body 200 through a relatively outer region of the top. At this time, the box 10 is only subjected to the vertical force of the body 200, reducing the force transmission path and making it more conducive to improving the rigidity of the whole vehicle and the lateral compression resistance.

[0299] Understandably, the top surface h of the housing 10 may include other regions besides the first region ha and the second region hb. These other regions may be located between the two regions, on the periphery of the two regions, or inside the two regions. This application does not specifically limit this.

[0300] In some embodiments, please refer to Figures 13 to 14 The distance L2 between the geometric centers of the orthographic projections of every two adjacent mounting parts 13a3 in the second region hb is 80mm-500mm.

[0301] Orthographic projection refers to the projection of parallel projection lines perpendicular to the projection plane, that is, projecting the mounting part 13a3 onto the second region hb along a direction perpendicular to the second region hb. When the mounting part 13a3 is connected to the external device, each mounting part 13a3 has a mounting force point. The geometric center of the orthographic projection of each mounting part 13a3 onto the second region hb is the mounting force point. The distance between any 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 to improve the connection strength between the battery 100 and the external device.

[0302] In one specific embodiment, when the external device is the body 200 of a vehicle 1000, a mounting part 13a3 is provided, including multiple mounting holes k1. The battery box 10 is connected to the body 200 through the multiple mounting holes k1. The distance L2 between the geometric centers of adjacent mounting holes k1 is within a limited range to ensure that the setting distance between mounting holes k1 (i.e., distance L2) is controllable. By controlling the setting distance between mounting holes k1, the multiple mounting positions on the box 10 are basically evenly distributed, so that the body 200 is subjected to uniform force, thereby improving the connection rigidity between the body 200 and the box 10 at various positions.

[0303] Understandably, in some other embodiments, if personalized settings are required, such as dividing the mounting section 13a3 into a dense mounting area and a sparse mounting area, the distance between each mounting hole k1 in the dense mounting area (i.e., distance L2) can be set as close as possible to the 80mm side, and the distance between each mounting hole k1 in the sparse mounting area (i.e., distance L2) can be set as close as possible to the 500mm side, so as to meet the personalized needs of local dense mounting and local sparse mounting.

[0304] In some embodiments, please refer to Figures 13 to 14 The distance L2 between the geometric centers of the orthographic projections of every two adjacent mounting parts 13a3 in the second region hb is 80mm-300mm.

[0305] A distance of 80mm-300mm from L2 ensures both uniform connection between the battery 100 and the external device, as well as strong connection between the battery 100 and the external device.

[0306] In some embodiments, please refer to Figures 13 to 14 The top surface h of the housing 10 also forms a sealing area hc, which is located between the first region ha and the second region hb, and surrounds the first region ha. The sealing area hc is used to install the seal 12, which is used to contact the external device.

[0307] The sealing area hc is also part of the top surface h of the housing 10. It is located between the first region ha and the second region hb to separate the first region ha and the second region hb and form a non-connected relationship. The area of ​​the sealing area hc should not be too large. Its main function is to install the sealing element 12 to achieve mutual isolation between the first region ha and the second region hb. It is designed to conform to the size, volume and shape of the sealing element 12 as much as possible to ensure that the sealing element 12 is fully assembled in the sealing area hc.

[0308] Understandably, the seal 12 exists in different states within the sealing area hc. When the seal 12 is in contact with the external device and the housing 10 is fixedly connected to the external device, the seal 12 is in a compressed state, and it will undergo a certain deformation to ensure sealing. When the battery 100 is separated from the external device, the seal 12 returns to its original state.

[0309] In a specific embodiment, such as the external device being the body 200 of a vehicle 1000, the battery 100 can be installed at the bottom of the body 200 and sealed to the body 200 through the seal 12 on the sealing area hc. In this case, the first area ha forms the closed interior of the body 200, and the second area hb is the exterior 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 impact the interior of the body 200, thereby achieving the sealing and structural reliability of the interior of the body 200.

[0310] Understandably, when the housing 10 includes a seal 12, the seal 12 is installed in the sealing area hc, sealing and isolating the first area ha and 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. These other areas can be located inside the first area ha or outside the second area hb; this application does not specifically limit this.

[0311] In some embodiments, please refer to Figures 13 to 14 The shortest distance L1 between the geometric center of the orthographic projection of the mounting part 13a3 in the second region hb and the outer edge of the sealing area hc is 30mm-200mm.

[0312] Projecting the mounting portion 13a3 onto the second region hb along a direction perpendicular to the second region hb, each mounting portion 13a3 has a mounting force point when connected to an external device. The geometric center of the orthographic projection of each mounting portion 13a3 onto the second region 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 region hb and the outer edge of the sealing region hc is the shortest distance between the mounting force point of each mounting portion 13a3 and the outer edge of the sealing region hc.

[0313] The outer edge of the sealing area hc is the boundary line shared by the sealing area hc and the second area hb. Naturally, the sealing area hc also has an inner edge, which is the boundary line shared by the sealing area hc and the first area ha. When assembling the seal 12, the two side edges of the seal 12 coincide with the inner and outer side edges of the sealing area hc, so that the seal 12 completely covers the sealing area hc.

[0314] The shortest distance L1 between the geometric center of the mounting part 13a3 in the orthographic projection of the second region 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 part 13a3 to the outer edge of the sealing area hc, so as to ensure that the distance between the seal 12 and the mounting part 13a3 is within a limited range.

[0315] In a specific embodiment, such as the external device being the body 200 of vehicle 1000, the shortest distance (i.e., distance L1) between the mounting force point of the mounting part 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 part 13a3 from being too far from the seal 12. On the one hand, this ensures the sealing effect of the seal 12 on the inside of the body 200, and on the other hand, it reduces the mounting torque of each mounting part 13a3 on the body 200, effectively shortening the mounting arm and ensuring the connection rigidity between the battery 100 and the body 200.

[0316] In some embodiments, please refer to Figures 13 to 14 The shortest distance L1 between the geometric center of the orthographic projection of the mounting part 13a3 in the second region hb and the outer edge of the sealing area hc is 50mm-100mm.

[0317] Within a range of 50mm-100mm, the distance between the mounting point of the mounting part 13a3 and the seal 12 can be avoided from being too far, thereby ensuring the sealing and isolation effect of the seal 12 on the first region ha and the second region hb, while also ensuring the connection strength between the battery 100 and the external device.

[0318] In some embodiments, the sealing region hc and the second region hb are coplanar.

[0319] Coplanarity, also known as coplane, means that the sealing region hc and the second region hb occupy the same plane in three-dimensional space. In this case, both the sealing region hc and the second region hb are constructed as flat planes and there is no angle between them.

[0320] In one specific embodiment, when the external device is the body 200 of the vehicle 1000, and the box 10 is mounted on the bottom of the body 200 via the top, the sealing area hc and the second area hb have the same height in the vertical direction. The sealing area hc is used to install the sealing element 12 to perform the sealing function, and the second area hb is constructed with a mounting element to perform 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. Since the mounting force point and the sealing element 12 only bear the force in the vertical direction, the lateral structural force of the box 10 and the body 200 is reduced, and the rigidity of the vehicle 1000 is improved.

[0321] In some embodiments, please refer to Figure 11 The first region ha, the second region hb, and the sealed region hc are coplanar.

[0322] At this time, the plane containing the first region ha, the second region hb, and the sealing region hc is in contact with the external device. The top surface h of the housing 10 has a large contact area with the external device, which helps to improve the reliability of the connection between the housing 10 and the external device. At the same time, the top structure of the housing 10 is relatively flat and more aesthetically pleasing.

[0323] 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 10 are all coplanarly arranged, ensuring that the internal and external areas of the body 200 of the box 10 only bear force in the vertical direction, thereby further reducing the lateral structural force of the vehicle 1000.

[0324] In some embodiments, please refer to Figure 14 When the mounting part 13a3 includes at least one mounting hole k1, all mounting holes k1 penetrate the second region hb.

[0325] For an introduction to the mounting hole k1, please refer to the above description, which will not be repeated here. When the mounting hole k1 is set through the second area hb, the connector can connect from the outermost second area hb of the top of the box 10 to the top of the box 10 when connecting the box 10 and the external device, so as to improve the connection strength between the box 10 and the external device.

[0326] In some embodiments, please refer to Figure 14 There is a reserved distance between the outer edge of the sealing area hc near the second area hb and the circumferential sidewall n of the main body 11.

[0327] The description of the circumferential sidewall n hole of the main body 11 can be found in the above description and will not be repeated here. The outer edge of the sealing area hc near the second area hb is not coplanar with the plane of the circumferential sidewall n of the main body 11 in the vertical direction, so that there is a certain reserved distance between the outer edge of the sealing area hc and the outer edge of the top surface h1 of the main body 11.

[0328] When the seal 12 is assembled and the seal 12 is not 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 the external device, the seal 12 deforms and overflows from the sealing area hc on both sides. 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.

[0329] A reserved distance is set between the outer edge of the sealing area hc near the second area hb and the axial sidewall of the main body 11, which can provide sufficient deformation space for the deformation of the seal 12, and prevent the seal 12 from overflowing beyond the top surface h1 of the main body 11 to other areas on the top of the box 10 and interfering with the structure on other areas.

[0330] In some embodiments, please refer to Figure 11 and Figure 13 The top surface h1 of the main body 11 defines at least a portion of the top surface h of the box 10.

[0331] The top surface h1 of the main body 11 refers to the side surface of the main body 11 located at its top and facing away from the receiving cavity s. When the housing 10 includes both the main body 11 and the side beam 13 in the above embodiments, the top surface h of the housing 10 can be jointly defined by the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. The top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can be coplanar. In this case, the contact area between the top surface h of the housing 10 and the external device is larger, which helps to improve the reliability of the connection between the housing 10 and the external device. At the same time, the top structure of the housing 10 is flatter and more aesthetically pleasing. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can also be non-coplanar.

[0332] In other embodiments, the box body 10 may also include other structures besides the main body 11 and the side 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 side beams 13, and the top surfaces of the other structures.

[0333] Understandably, the first region ha and the sealing region hc are located on the top surface h1 of the main body 11. In addition to the first region ha and the sealing region hc, the top surface h1 of the main body 11 may also include other regions, which are not specifically limited here.

[0334] 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 main body 11.

[0335] The top surface h1 of the main body 11 is divided into a first region ha, a sealing region hc surrounding the first region ha, and a second region hb surrounding the sealing region hc. When the sealing element 12 in the sealing region hc undergoes compression deformation, one edge of the sealing element 12 extends into the second region hb on the top surface h1 of the main body 11.

[0336] Understandably, the second region hb on the top surface h1 of the main body 11 is the reserved distance between the outer edge of the sealing area hc and the circumferential sidewall n of the main body 11, so as to ensure that sufficient deformation space is reserved for the deformation of the seal 12, and to prevent the seal 12 from overflowing onto the side beam 13 when it deforms beyond the top surface h1 of the main body 11.

[0337] In some embodiments, the mounting portion 13a3 is located in a second region hb defined by the top surface h2 of the lateral beam 13.

[0338] The description of the mounting hole k1 can be found in the above description and will not be repeated here. The mounting hole k1 is located in the second region hb defined by the top surface h2, and also has the beneficial effect of the mounting part 13a3 being located on the top of the side beam 13, which will not be repeated here.

[0339] When the housing 10 includes both the main body 11 and the side beam 13 as described in the above embodiments, the top surface h of the housing 10 can be defined by the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. A reserved distance is provided between the outer edge of the sealing area hc near the second region hb and the axial sidewall of the main body 11. This allows sufficient deformation space for the seal 12, preventing it from overflowing from the top surface h1 of the main body 11 to the top surface h2 of the side beam 13 during deformation, thus avoiding interference with the mounting portion 13a3 on the side beam 13.

[0340] In some embodiments, please refer to Figure 14 The mounting part 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 projection of each two adjacent mounting parts 13a3 in the second region hb is 80mm-500mm.

[0341] The descriptions of the first sub-beam 13a1 and the second sub-beam 13a2 can be found above and will not be repeated 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, extending along the first direction F1 and / or the second direction F2, thereby forming a uniform mounting and fixing with the external device in multiple directions, further improving the connection between the external device and the housing 10.

[0342] Furthermore, the distance between the geometric centers of the orthographic projections of two adjacent mounting parts 13a3 in the second region hb and the distance between the geometric centers of adjacent mounting holes k1 are limited in a certain set direction, so as to ensure that the setting distance between mounting holes k1 is controllable along the extension direction of the first sub-beam 13a1 and along the extension direction of the second sub-beam 13a2, so that the vehicle body 200 is subjected to uniform force.

[0343] Understandably, when the box body 10 includes the central channel beam 16, the central channel beam 16 is located in the first region ha, so that the central channel beam 16 can be located in the central region of the body 11.

[0344] In one embodiment, the housing 10 includes the aforementioned main body 11 and the aforementioned high-voltage chamber 15. The aforementioned battery cavity s1 is formed within the aforementioned main body 11. The aforementioned high-voltage chamber 15 is disposed at the aforementioned top of the aforementioned main body 11 and located in the aforementioned first region ha. The aforementioned high-voltage chamber 15, either by itself or together with the aforementioned main body 11, forms the aforementioned high-voltage cavity s2. Since the first region ha forms most of the area at the top of the main body 11, arranging the high-voltage chamber 15 in the first region ha can improve the space utilization rate of the first region ha.

[0345] According to some embodiments of this application, the housing 10 has a battery chamber s1 and a high-voltage chamber s2 that are independently arranged. 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 (not shown). When the battery chamber s1 and the high-voltage chamber s2 are independently arranged, if the high-temperature gas leaked due to the thermal failure of the battery cell 20 in the battery chamber s1 will not enter the high-voltage box, thereby preventing thermal damage to the high-voltage control system in the high-voltage box. This ensures the normal control function of the high-voltage control system and improves the safety performance of the battery 100.

[0346] On the other hand, according to some embodiments of this application, please refer to Figure 3 and Figure 4 This application provides a battery 100, including a housing 10 and a battery cell 20 as described in any of the above embodiments, wherein the battery cell 20 is housed within a receiving cavity s. Since the battery 100 includes the aforementioned housing 10, it possesses all the beneficial effects of the aforementioned housing 10, which will not be elaborated upon here.

[0347] 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.

[0348] The high-voltage box is a crucial safety barrier for the 100 battery packs. It houses a high-voltage control system, primarily used for: connecting or disconnecting the high-voltage circuit according to the vehicle's electronic control requirements; providing current and leakage detection terminals; controlling load disconnection when the external current of the 100 battery packs is too high; disconnecting the high-voltage circuit to prevent the 100 battery packs from catching fire when a short circuit occurs in the external wiring of the 100 battery packs; and conveniently disconnecting the high-voltage circuit when maintaining the 100 battery packs.

[0349] At this point, the current from all the individual battery cells 20 is connected and collected through the high-voltage box, and safe electrical energy is provided to the outside, enabling the battery 100 to safely supply power to the outside. Regarding the specific structure of the high-voltage box, refer to conventional configurations in the field; this application does not involve specific improvements to the high-voltage box.

[0350] In some embodiments, please refer to Figure 10 and Figure 20 The housing 10 includes a main body 11, which encloses and forms a receiving cavity s. The main body 11 includes a support member 11a located at the top of the housing 10 and used to define the receiving cavity s. The battery cell 20 is disposed on the support member 11a.

[0351] For a description of the main body 11, the top of the housing 10, and the support component 11a, please refer to the above description, which will not be repeated here. At this time, the support component 11a is a component that can support the weight of the battery cell 20, and can be a support plate, support block, support piece, support frame, etc., and is not specifically limited.

[0352] Specifically, the battery cell 20 can be positioned below the support member 11a, and together with the support member 11a, it can bear the force on the top of the battery 100 housing 10, thereby improving the rigidity of the top of the battery 100 housing 10.

[0353] In some embodiments, please refer to Figure 10 and Figure 20 The battery cell 20 is suspended on the support member 11a.

[0354] The battery cell 20 being suspended from the support member 11a means that the battery cell 20 is positioned vertically below the support member 11a, and the weight of the battery cell 20 is borne by the support member 11a. Methods of suspending the battery cell 20 from the support member 11a include: the battery cell 20 being directly adhered to the lower surface of the support member 11a; the battery cell 20 being connected to the support member 11a via fasteners and positioned below the support member 11a; and the battery cell 20 being hung on the support member 11a via hooks or the like and positioned below the support member 11a.

[0355] At this time, the battery cell 20 is suspended below the support member 11a, and the bottom cover 11c is located at the bottom of the housing 10. When repairing the inside of the battery 100, the battery cell 20 can be exposed by removing the bottom cover 11c without removing the support member 11a, making the maintenance of the battery 100 more convenient. At the same time, when repairing the battery 100, the battery cell 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 bears the load, the battery cell 20 only needs to be removed and installed from below the support member 11a without removing the support member 11a, which facilitates the maintenance of the battery 100.

[0356] In some embodiments, the battery cell 20 is bonded to the carrier 11a.

[0357] Specifically, the battery cell 20 and the carrier 11a can be bonded together using adhesives such as epoxy resin or acrylic adhesive, without limitation. This bonding between the battery cell 20 and the carrier 11a not only facilitates connection but also simplifies the structure of the battery 100.

[0358] Figure 22 This is a schematic diagram of the structure of a battery cell 20 in some embodiments of this application.

[0359] In some embodiments, please refer to Figure 22 The outer surface of the battery cell 20 facing the support member 11a is the first outer surface m1. The battery cell 20 includes an electrode terminal 21a, which is arranged on the outer surface of the battery cell 20 other than the first outer surface m1.

[0360] As described above, electrode terminal 21a is used for electrical connection with electrode assembly 23 inside battery cell 20 to output or input electrical energy to battery cell 20. Electrode terminal 21a extends at least partially outside battery cell 20 for external electrical connection. Series and parallel connections between battery cells 20 are achieved through series and parallel connections between their respective electrode terminals 21a. Electrode terminal 21a is conductive to enable electrical transmission and can be aluminum electrode, copper electrode, etc.

[0361] Electrode terminals 21a are arranged on the outer surface of the battery cell 20, excluding the first outer surface m1. The first outer surface m1 faces the support member 11a and is typically a smooth surface without any protruding or recessed structures such as electrode terminals 21a or liquid injection holes. When the battery cell 20 is suspended from the support member 11a, the first outer surface m1 is the upward-facing outer surface of the battery cell 20. In one specific embodiment, the battery cell 20 includes the housing 22 and end cap 21 mentioned above. The housing 22 and end cap 21 form the internal environment of the battery cell 20 that accommodates the electrode assembly 23. The end cap 21 is located at one end of the housing 22, and the electrode terminals 21a are arranged on the end cap 21. In this case, any outer surface of the housing 22 can serve as the first outer surface m1 of the battery cell 20.

[0362] Electrode terminal 21a includes a positive terminal and a negative terminal. The positive terminal is used for electrical connection with the positive electrode plate in the electrode assembly 23, and the negative terminal is used for electrical connection with the negative electrode plate in the electrode assembly 23. It should be noted that the positive and negative terminals can be arranged on the same outer surface of the battery cell 20 (e.g., a square battery cell), or they can be arranged on two different outer surfaces of the battery cell 20 (e.g., a cylindrical battery cell). When the positive and negative terminals 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 these two outer surfaces.

[0363] In addition to the individual battery cells 20, the battery 100 typically includes components such as sampling harnesses for electrically connecting each battery cell 20, high-voltage wiring harnesses, and protective structures for protecting the battery cells 20. In this case, the electrode terminals 21a are arranged on surfaces of the battery cells 20 other than the first outer surface m1. When the sampling harnesses, high-voltage wiring harnesses, and protective structures are placed on the electrode terminals 21a, they are not restricted by the support member 11a and can be arranged through the space between the battery cells 20 and other structures of the main body 11 other than the support member 11a (such as 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), making the arrangement of each component more convenient. Simultaneously, since the first outer surface m1 is a smooth surface, it can be fitted to the support member 11a, thus achieving a close fit between the battery cells 20 and the support member 11a without needing to reserve space between them, which helps improve the space utilization of the battery 100.

[0364] 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.

[0365] The second outer surface m2 is the outer surface of the battery cell 20 that is set opposite to the first outer surface m1. When the battery cell 20 is suspended on the support member 11a, the second outer surface m2 is opposite to the bottom cover 11c.

[0366] 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 it. 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 and other objects on the ground may 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 transmission of external forces to the battery cell 20 and prevent it from affecting the battery cell 20.

[0367] When the battery cell 20 is spaced apart from the bottom cover 11c, a buffer space exists 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 connecting piece connected to the electrode terminal 21a can be arranged within the buffer space. Simultaneously, the buffer space also has the aforementioned ability to prevent external forces striking the bottom cover 11c from damaging the battery cell 20. Therefore, the buffer space not only interrupts the influence of external forces but also allows for the arrangement of wiring harnesses, achieving two benefits at once. Furthermore, the space utilization of the buffer space and the battery 100 is also improved.

[0368] On the other hand, this application also provides an electrical device. This electrical device includes the battery 100 provided in any of the above embodiments, and the battery 100 is used to provide electrical energy to the electrical device. The description of the electrical device is as described above and will not be repeated here.

[0369] Since the power device includes the battery 100 described above, it possesses all the beneficial effects described in the above embodiments, which will not be elaborated here.

[0370] Figure 1 This is a schematic diagram of the battery 100 applied to the vehicle body 200 in some embodiments of this application.

[0371] In some embodiments, the electrical device includes a vehicle 1000, and a battery 100 is disposed at the bottom of the vehicle body 200. The description of the vehicle 1000 is as described above and will not be repeated here.

[0372] The vehicle body 200 of vehicle 1000 refers to the part of vehicle 1000 used for carrying passengers and cargo, including the driver's cab, passenger compartment, engine compartment, luggage compartment, etc. The vehicle body 200 typically includes an outer shell and doors, windows, trim pieces, seats 300, air conditioning devices, etc., mounted on the outer shell. The outer shell typically refers to the structure composed of the main load-bearing components of vehicle 1000, such as longitudinal beams, cross beams, chassis, and pillars, as well as the sheet metal parts connected to them. In the embodiments of this application, the battery 100 being located at the bottom of the vehicle body 200 mainly refers to the battery 100 being located at the bottom of the outer shell.

[0373] At this point, placing the battery 100 at the bottom of the vehicle body 200 will not occupy the internal space of the vehicle body 200, which helps to reduce the size and weight of the vehicle body 200.

[0374] 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.

[0375] The chassis, as part of the vehicle body 200, is 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.

[0376] The chassis is located on top of the underbody 10 of the vehicle body 200, directly serving as at least a part of the chassis. That is, the top of the underbody 10 is used to form at least a part of the chassis of the vehicle body 200. In this way, the top of the underbody 10 is integrated with the chassis of the vehicle body 200, so that the space occupied by the gap between the conventional chassis and the battery 100 can be allocated to the battery 100 to increase the space of the battery 100. This helps to increase the energy of the battery 100, thereby increasing the driving range of the vehicle 1000.

[0377] According to some embodiments of this application, the electrical device includes a vehicle 1000, and a battery 100 is 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 member 11a located at its top. The battery cells 20 are located within the housing 10 and suspended on the support member 11a, with the electrode terminals 21a of the battery cells 20 located on the outer surface of the battery cells 20 facing away from the support member 11a. The support member 11a forms at least a part of the chassis of the vehicle 1000. In this case, the battery 100 is suspended solely on the support member 11a, which can increase the strength of the support member 11a and thus increase the strength of the top of the battery cells 20, enabling the support member 11a to meet certain stress requirements when serving as a chassis. Meanwhile, the electrode terminals 21a of the battery cell 20 are away from the support member 11a, so the battery cell 20 can be directly installed on the support member 11a, eliminating the gap between the battery cell 20 and the support member 11a. The saved gap can be used to increase the installation space of the battery cell 20, thereby increasing the energy of the battery 100 and thus improving the range of the vehicle 1000.
