[0001] This application relates to the technical field of batteries, and in particular, to a housing, a battery, and a power consumption device.
Background Art
[0002] As new energy technologies become increasingly mature, new energy vehicles are gradually coming into the public's view. The main 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 usually includes a battery cell and a high-voltage case, and the battery cell supplies power to the outside through the high-voltage case. In related technologies, when a large amount of heat is generated due to a thermal failure of the battery cell, the equipment in the high-voltage case is easily damaged, reducing the safety of the battery.
Summary of the Invention
[0008] In some embodiments, the high-voltage chamber is installed protruding from the top of the main unit. When the battery housing is used as the vehicle chassis, the high-voltage chamber is located at the top of the main unit, so it is not exposed to the outside of the vehicle and is protected from external impacts (such as stones flying up while the vehicle is in motion), making the high-voltage chamber safer.
[0009] In some embodiments, the high-pressure chamber is installed close to the top outer edge of the main body. In this case, the high-pressure chamber can be positioned corresponding to the passenger space behind the vehicle's driving space, and in particular, corresponding to below the seats in the passenger space, without occupying the vehicle's moving space.
[0010] In some embodiments, the body includes a carrier and a frame formed by surrounding a cavity through which at least its top edge is installed, the carrier covering the top edge of the cavity, the carrier and frame forming by surrounding at least a portion of the housing cavity, and a high-pressure chamber installed on top of the carrier, surrounding the high-pressure cavity either by itself or together with the carrier. In this case, since the carrier constitutes most of the top of the body, installing the high-pressure chamber on top of the carrier provides a larger mounting space for the high-pressure chamber and makes the installation more stable.
[0011] In some embodiments, the top of the housing is configured to have a mounting portion, and the battery is attached to an external device via the mounting portion. The mounting portion is a dedicated structure provided on the top of the housing for connecting to a connecting material (e.g., bolt, rivet, etc.) of an external device, where one end of the connecting material can be connected to the mounting portion, and the other end of the connecting material is connected to the external device, thereby permanently connecting the battery to the external device.
[0012] In some embodiments, the mounting portion includes at least one mounting hole provided on the top of the housing. The mounting hole can be formed on the top surface of the housing by drilling, and the mounting hole allows the connecting material to pass through the mounting hole, thereby achieving fixation in conjunction with the structure in which the mounting hole is provided, and enabling connection between the external device and the top surface of the housing via the connecting material.
[0013] In some embodiments, the housing also includes a seal positioned at the top of the housing for a sealed connection to an external device. In this case, the battery housing and the external device are sealed via the seal, ensuring a secure and low-cost connection.
[0014] In some embodiments, the top surface of the housing is formed with a first region, a second region, and a seal area located between them, the seal area surrounding the first region, the seal being attached to the seal area, and the mounting portion being located in the second region. By forming the mounting portion in the second region, the housing is connected to the vehicle body via a relatively outer region of the top, in which case the housing is subjected only to vertical forces from the vehicle body, reducing the force transmission path and being advantageous in improving the overall rigidity and lateral pressure resistance of the vehicle.
[0015] In some embodiments, the housing includes a main body with a battery cavity formed inside, and a high-pressure chamber located at the top of the main body, situated in a first region, and surrounding the high-pressure cavity either by itself or together with the main body. Since the first region forms a large portion of the top of the main body, placing the high-pressure chamber in the first region can improve the space utilization rate of the first region.
[0016] In a second aspect, the application also provides a battery comprising the above-mentioned housing, a single battery housed in a battery cavity, and a high-voltage case housed in a high-voltage cavity.
[0017] In some embodiments, the housing includes a body that surrounds and forms a housing cavity, the body includes a carrier located at the top of the housing that defines the battery cavity, and the individual battery is placed on the carrier. The individual battery is positioned below the carrier and, by sharing the load-bearing capacity of the top of the battery housing with the carrier, the rigidity of the top of the battery housing can be increased.
[0018] In some embodiments, the battery unit is suspended from a carrier, or suspended below the carrier, with a bottom cover at the bottom of the housing. When repairing the inside of the battery, the battery unit can be exposed by removing the bottom cover without removing the carrier, making battery maintenance more convenient. Alternatively, when repairing the battery, the battery unit can be attached to and detached from the carrier from below. In particular, if the carrier is subjected to force as at least part of the vehicle's chassis, the battery unit can be attached and detached from below the carrier without removing the carrier, making battery repair easier.
[0019] In some embodiments, the battery itself is bonded to the carrier. This bonding of the battery to the carrier not only facilitates connection but also simplifies the battery's structure.
[0020] In some embodiments, the outer surface of the battery unit facing the carrier is the first outer surface, and the battery unit includes electrode terminals located on the outer surfaces of the battery unit other than the first outer surface. In this case, the electrode terminals are located on the outer surfaces of the battery unit other than the first outer surface, and various components connecting each electrode terminal (e.g., sampling harness, high-voltage harness, guard structure, etc.) can be arranged through the space between the battery unit and the bottom cover, and / or the space between the battery unit and the inner surface of the main body, making the arrangement of each component more convenient. Furthermore, in this case, by connecting the first outer surface, which does not have electrode terminals, to the carrier, close contact between the battery unit and the carrier can be achieved, saving space between the battery unit and the carrier and improving the space utilization rate of the battery.
[0021] In some embodiments, the battery unit has a second outer surface positioned opposite to a first outer surface, and the electrode terminals are located on the second outer surface. In this case, a buffer space is formed between the second outer surface and the bottom cover, where the portion of the electrode terminals that protrudes from the battery unit is located, and wire harnesses and connecting pieces connected to the electrode terminals can be placed within the buffer space. Furthermore, the buffer space can block external forces hitting the bottom cover from acting on the battery unit and damaging it. Thus, the buffer space not only blocks the effects of external forces but also allows for the layout of wire harnesses and the like, killing two birds with one stone.
[0022] In a third aspect, the application also provides a power consumption device including the battery described above, which is used to provide electrical energy to the power consumption device.
[0023] In some embodiments, the power consumption device includes a vehicle, with the battery installed at the bottom of the vehicle's body. By installing the battery at the bottom of the vehicle body, it does not occupy space inside the vehicle, contributing to a reduction in the volume and weight of the vehicle.
[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 positioned to form at least a part of the vehicle body's chassis. In this case, the space occupied by the gap between the conventional chassis and the battery is divided into space for expanding the battery within the battery, thereby improving the battery's energy and the vehicle's driving range.

[0036] Currently, given the development of the market, the applications of batteries are expanding more and more. Batteries are used not only in energy storage and power systems such as hydroelectric, thermal, wind, and solar power plants, but also in electric vehicles such as electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As the application fields of batteries expand, the market demand continues to increase.
[0037] The inventors note that in related technologies, the individual battery cells and the high-voltage case within a battery are located in the same space. When a battery cell experiences a thermal failure, it releases a large amount of heat. Since the high-voltage case is located in the same space as the individual battery cells, it is affected by the heat released by the individual battery cells. As a result, the high-voltage control system installed inside the high-voltage case is susceptible to heat and damage, leading to a loss of control of the high-voltage control system, causing a safety accident and significantly reducing the safety of the battery.
[0038] To enhance battery safety, the applicant's research suggests that separating the high-voltage case from the space in which the individual battery is located can prevent heat generated from the individual battery from damaging the high-voltage control system within the high-voltage case.
[0039] Based on the above considerations, the inventors have diligently studied and, as a result, have designed a battery housing for a battery, in which a battery cavity for housing a single battery and a high-pressure cavity for housing a high-pressure case are provided independently of each other. When the battery cavity is provided independently of the high-pressure cavity, high-temperature gas leaking due to thermal failure of a single battery in the battery cavity does not enter the high-pressure case, and furthermore, does not cause thermal damage to the high-pressure control system in the high-pressure case, thereby ensuring the normal control function of the high-pressure control system and improving the safety performance of the battery.
[0040] The batteries disclosed in the embodiments of this application can be used in power-consuming devices such as vehicles, ships, or aircraft, but are not limited thereto. A power supply system comprising the batteries disclosed in this application can be used in such power-consuming devices. The mounting body according to this application is a structure for mounting a battery in a power-consuming device.
[0041] Embodiments of this application provide a power consumption device that uses a battery as a power source, which may be, but is not limited to, a mobile phone, tablet, notebook computer, electric toy, power tool, battery car, electric vehicle, steamship, spacecraft, etc. Here, electric toys may include stationary or mobile electric toys such as game consoles, electric vehicle toys, electric steamship toys, electric airplane toys, etc., and spacecraft may include aircraft, rockets, space shuttles, and spacecraft, etc.
[0042] In the following embodiments, for the sake of convenience of explanation, we will describe an example in which one of the power consumption devices according to an embodiment of this application is a vehicle 1000.
[0043] Referring to Figure 1, Figure 1 is a schematic diagram showing the structure of a vehicle 1000 provided by some embodiments of the present application. The vehicle 1000 may be a gasoline vehicle, a gas vehicle, or a new energy vehicle, and the new energy vehicle may be an electric vehicle, a hybrid vehicle, or a range-extended vehicle. Inside the vehicle 1000 is a battery 100, which may be installed at the bottom, top, or rear of the vehicle 1000 when the battery 100 is used in the vehicle. The battery 100 can be used to supply power to the vehicle 1000, for example, the battery 100 can be used as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller and a motor, the controller controlling the battery 100 to supply power to the motor, for example, for the power demands of starting, navigating, and driving the vehicle 1000.
[0044] In some embodiments of this application, the battery 100 can function not only as an operating power source for the vehicle 1000, but also as a power source for the vehicle 1000, providing driving force to the vehicle 1000 in place of or in part of gasoline or natural gas.
[0045] Referring to Figure 2, Figure 2 is a schematic diagram showing the structure of a vehicle 1000 provided by some embodiments of this application. The battery unit 20 is the smallest unit constituting the battery 100. As shown in Figure 2, the battery unit 20 comprises an end cap 21, a housing 22, an electrode assembly 23, and other functional components.
[0046] The end cap 21 is a component that covers the opening of the housing 22 in order to isolate the internal environment of the battery unit 20 from the external environment. While not limited to this, the shape of the end cap 21 can be adapted to the shape of the housing 22 for fitting into the housing 22. Selectively, the end cap 21 may be formed from a material having a certain hardness and strength (e.g., an aluminum alloy), so that the end cap 21 is less likely to deform during pressure impact, thereby increasing the structural strength of the battery unit 20 and improving safety. Functional components such as electrode terminals 21a may be provided on the end cap 21. The electrode terminals 21a can be used for electrical connection to an electrode assembly 23 for outputting or inputting electrical energy from the battery unit 20. In some embodiments, the end cap 21 may be provided with a pressure release mechanism for releasing internal pressure when the internal pressure or temperature of the battery unit 20 reaches a threshold. The material of the end cap 21 may vary, such as copper, iron, aluminum, stainless steel, aluminum alloy, or plastic, but there are no special limitations in the embodiments of this application. In some embodiments, the inside of the end cap 21 may be provided with an insulating material that can be used to isolate the electrical connection portion 11a2 in the housing 22 from the end cap 21 in order to reduce the risk of short circuits. The insulating material may be, for example, plastic, rubber, or the like.
[0047] The housing 22 is an assembly for fitting the end cap 21 to form the internal environment of the battery unit 20, which can be used to house the electrode assembly 23, electrolyte, and other components. The housing 22 and the end cap 21 may be separate components, or an opening may be provided in the housing 22 and the end cap 21 may cover this opening to form the internal environment of the battery unit 20. The end cap 21 and the housing 22 may be integrated, or, more specifically, the end cap 21 and the housing 22 may form a common connection surface before other components enter the housing, and the end cap 21 may cover the housing 22 when it becomes necessary to package the inside of the housing 22. The housing 22 can have multiple shapes and sizes, such as a rectangular parallelepiped, cylindrical shape, or hexagonal prism shape. 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 may vary, for example, copper, iron, aluminum, stainless steel, aluminum alloy, plastic, etc., but no special limitations are imposed in the embodiments of this application.
[0048] The electrode assembly 23 is a component in the battery unit 20 that undergoes an electrochemical reaction. The housing 22 may contain one or more electrode assemblies 23. The electrode assembly 23 is mainly formed by winding or laminating a positive electrode sheet and a negative electrode sheet, and usually a separator is provided between the positive electrode sheet and the negative electrode sheet. The portions of the positive electrode sheet and the negative electrode sheet that have active materials constitute the main body 11 portion of the electrode assembly 23, while the portions that do not have active materials constitute the main body 11 portion, respectively. The positive electrode tabs and negative electrode tabs may be located in common at one end of the main body 11 portion, or they may be located at both ends of the main body 11 portion, respectively. During charging and discharging of the battery, the positive electrode active materials and negative electrode active materials react with the electrolyte, and the electrode tabs are connected to the electrode terminals 21a to form a current loop.
[0049] Figure 3 is an exploded schematic diagram of a battery 100 provided by some embodiments of the present application, which includes a battery unit 20 and a housing 10 having a housing cavity s for housing the battery unit 20.
[0050] In the battery 100, there may be multiple individual battery units 20, and multiple individual battery units 20 can be connected in series, parallel, or mixed configurations, where mixed configuration means that multiple individual battery units 20 can be connected in series or parallel. Multiple individual battery units 20 can be directly connected in series, parallel, or mixed configurations to each other, and the entire assembly of multiple individual battery units 20 is housed in the housing 10. Of course, the battery 100 may also be configured as a battery module by connecting multiple individual battery units 20 in series, parallel, or mixed configurations, and multiple battery modules may be connected in series, parallel, or mixed configurations to form a single unit, which is then housed in the housing 10. The battery 100 may also include other structures, for example, it may include a merging member to realize electrical connections between multiple individual battery units 20. Each individual battery unit 20 may be a secondary battery or a primary battery, and may be, but is not limited to, a lithium-sulfur battery, a sodium-ion battery, or a magnesium-ion battery. The individual battery unit 20 may be cylindrical, flattened, rectangular, or have other shapes.
[0051] The housing 10 may have multiple shapes, such as cylindrical or rectangular parallelepiped, and the specific configuration of the housing 10 can take on multiple structural forms.
[0052] According to some embodiments of this application, referring to Figure 3, the application provides a housing 10 for a battery 200, the housing 10 having a housing cavity for housing a battery unit 20. The housing 10 provides a housing space for a battery unit 20, and the housing can employ multiple structures. In some embodiments (as shown in Figure 3), the housing includes a first part 10A and a second part 10B that cover each other, and the first part 10A and the second part 10B together can define a housing space for housing a battery unit. The second part 1 may be a hollow structure with one end open, and the first part 10A may be a plate-like structure that covers the open side of the second part so as to define a housing space together with the second part 10B. Alternatively, both the first part 10A and the second part 10B may be hollow structures with one end open, and the open side of the first part 10A covers the open side of the second part 10B. Of course, the housing 10 formed by the first part 10A and the second part 10B may have multiple shapes, such as cylindrical or rectangular parallelepiped shapes.
[0053] Figure 4 is an exploded view of another structure of battery 100 in some embodiments of this application. Figure 5 is an enlarged view of A in Figure 4. Figure 6 is a schematic diagram showing part of the structure of battery 100 in some embodiments of this application. Figure 7 is an enlarged view of location B in the structure shown in Figure 6, Figure 8 is a plan view of the structure shown in Figure 6, Figure 9 is a side view of the structure shown in Figure 6, and Figure 10 is a cross-sectional view of location CC in the structure shown in Figure 9.
[0054] In some embodiments, referring to Figure 4, the battery 100 is attached to an external device via the top of the housing 10.
[0055] The top surface of the housing 10 includes the top surface h of the housing 10 and other structures provided on the top surface h of the housing 10. The top surface h of the housing 10 is the upper vertical surface of the housing 10 in use. Other structures provided on the top surface h of the housing 10 include, but are not limited to, connecting members (e.g., bolts, rivets, etc.) that connect the top surface h of the housing 10 to the external device, and sealing structures (e.g., sealing strips, etc.) that seal the housing 10 to the external device.
[0056] An external device is a device for attaching the housing 10. The external device may be a local structure for attaching the housing 10 from among the power consumption devices described above, or it may be another structure that forms a power consumption device together with the battery 100. Taking a vehicle 1000 as an example of a power consumption device, the external device may be the vehicle body 200 of the vehicle 1000, and the battery 100 may be attached to the bottom of the vehicle body 200 and to the vehicle body 200 via its top.
[0057] In this configuration, the battery 100 is attached to the external device via the top of the housing 10, and the housing 10 is positioned at the bottom of the external device. This allows for a miniaturization of the connection structure between the housing 10 and the external device, resulting in a compact design at a lower cost.
[0058] Of course, in other embodiments as well, the battery 100 may be attached to an external device via the bottom or side of the housing 10.
[0059] In some embodiments, referring to Figure 4, the housing 10 includes a body 11 formed to surround the housing cavity s.
[0060] The main body 11 may be a single-piece molded structure or may be formed by combining multiple parts. The main body 11 is a hollow shell structure and can be understood as surrounding and forming a housing cavity s. Specifically, the main body 11 may be formed by combining a first sub-part (not shown) and a second sub-part (not shown). In one example, the first sub-part surrounds a housing cavity s with an opening at one end, and the second sub-part covers the opening of the housing cavity s. In another example, the first sub-part surrounds a first space with an opening at one end, and the second sub-part surrounds a second space with an opening at one end, so that the openings of both the first and second sub-parts cover each other, forming a housing cavity s consisting of a first space and a second space. The first and second sub-parts can be welded, locked, fastened together, etc. The first and second sub-parts may be made of plastic, metal, or other materials.
[0061] In some embodiments, referring to Figure 4, the top of the main body 11 forms at least a portion of the top of the housing 10.
[0062] The top of the main body 11 is a structure located at the uppermost vertical position of the main body 11, where the highest point of the main body 11 is the highest point of the housing 10, and the top of the main body 11 forms at least a part of the top of the housing 10. When the top of the main body 11 forms the entire top of the housing 10, the top of the main body 11 is the top of the housing 10, and the entire top of the housing 10 is involved in defining the housing cavity s. When the top of the main body 11 forms a part of the top of the housing 10, the top of the housing 10 also has a structure in which other parts, such as the side beams 13 which will be described in detail below, are not involved in defining the housing cavity s.
[0063] When the battery 100 is attached to the external device via the top surface of the housing 10, the top surface of the main unit 11 is also located at the position of the battery 100 that is closest to the external device, and the distance between the top surface of the main unit 11 and the external device is the distance between the highest point of the top surface of the main unit 11 and the external device located vertically above it.
[0064] Referring to Figure 6, it can be understood that the main body 11 has circumferential side walls n installed around the outer edge of its top.
[0065] The main body 11 has a top located at the uppermost position in the vertical direction, and of course a bottom located at the lowest position, the bottom may have a structure where the bottom surface is arranged on the bottom surface, or the bottom may be open.
[0066] The outer surface facing away from the housing cavity s of the structure sandwiched between the top and bottom forms a circumferential side wall n, and the direction of extension of the plane on which the circumferential side wall n is located intersects with the plane on which the top is located. The circumferential side wall n may be annular, rectangular, or the like, formed by multiple wall segments connected front to back, and details are shown below.
[0067] Referring to Figure 6, it can be understood that the enclosure 10 further has a top surface h that faces away from the housing cavity s.
[0068] The top surface h of the housing 10 is located on the surface facing away from the housing cavity s at the top of the housing 10. When the battery 100 is combined with the external device via the top of the housing 10, the top surface h is positioned facing the external device, forming the position where the battery 100 is closest to the external device.
[0069] In some embodiments, referring to Figure 6, the top surface h of the housing 10 is positioned to contact an external device (not shown) to which the battery 100 is attached.
[0070] The battery 100 is attached to the external device via the top of the housing 10, and one surface of the housing 10 facing away from the housing cavity s is in contact with the external device, so the connection structure between the housing 10 and the external device is smaller, lower cost, and more compact compared to a system where the top surface h of the housing 10 is not in contact with the external device.
[0071] In some embodiments, referring to Figure 6, the top of the housing 10 is configured to have a mounting portion 13a3, and the battery 100 is attached to an external device via the mounting portion 13a3.
[0072] The mounting portion 13a3 is part of the top of the housing 10 and does not participate in defining the housing cavity s. The mounting portion 13a3 is a dedicated structure provided on the top of the housing 10 for connecting to a connecting member (e.g., bolt, rivet, etc.) of an external device, with one end of the connecting member connectable to the mounting portion 13a3 and the other end of the connecting member connected to the external device to permanently connect the battery 100 to the external device. The top of the main body 11 is at least a part of the top of the housing 10, and the mounting portion 13a3 may be provided on the top of the main body 11, or on other structures constituting the top of the housing 10 (the top of the side beam 13, described later).
[0073] When attaching the battery 100 to the external device via the mounting portion 13a3, the top surface h of the housing 10 contacts and connects with the external device, improving connection strength while ensuring a compact connection structure between the housing 10 and the external device.
[0074] The mounting portion 13a3 itself may have a connecting function (e.g., a suspension ring), or a connecting material (e.g., a hook) corresponding to the external device may be provided to directly connect with the mounting portion 13a3. In other embodiments, the connection between the mounting portion 13a3 and the external device may be directly achieved by other methods, including but not limited to locking, plug joining, screw member joining, riveting, welding, and bonding, without providing a connecting material, and this application does not particularly limit this.
[0075] In some embodiments, referring to Figure 6, the mounting portion 13a3 includes at least one mounting hole k1 provided at the top of the housing 10.
[0076] Mounting holes k1 can be formed on the top surface of the housing 10 by drilling, and openings communicating with the holes and both ends of the holes are provided inside all of the mounting holes k1. These openings allow the connecting material to pass through the mounting holes, and together with the structure in which the mounting holes k1 are provided, fixing is achieved, and the external device and the top surface of the housing 10 are connected via the connecting material.
[0077] The connecting piece may also be a rivet. A fixing hole 11c3 is provided at the position of the external device corresponding to the mounting hole k1. After passing the rivet through the fixing hole 11c3 and the mounting hole k1, the two are secured with a nut. Alternatively, the connecting material can be a screw, the mounting hole k1 can be a screw hole, and the screw can be passed through the mounting hole k1 to connect it to the housing 10.
[0078] Specifically, by extending all of the mounting holes k1 in the vertical direction, the battery 100 can be fixed vertically to the bottom of the external device. In order to achieve connection stability between the top surface of the housing 10 and the external device, and uniformity of the force received by both, it is understood that elements such as the installation position and installation distance of all mounting holes k1 can be controlled, as detailed below.
[0079] It can be understood that the mounting portion 13a3 may have other attachmentable components, such as hooks, in addition to the mounting hole k1.
[0080] In some embodiments, referring to Figures 4 and 6, the body 11 includes a carrier 11a and a frame 11b formed by surrounding a cavity through which at least its top edge is installed, the carrier 11a covering the top edge of the cavity, and the carrier 11a and frame 11b forming by surrounding at least a partial housing cavity s.
[0081] The frame 11b itself is enclosed so as to form a cavity through which at least its top edge is installed, and the carrier 11a covers the top of the cavity, that is, the carrier 11a is located at the top of the housing 10 and defines the housing cavity s. The frame 11b and the carrier 11a may be made of the same material, such as aluminum alloy, copper alloy, steel, or plastic. Of course, the frame 11b, carrier 11a, and bottom cover 11c may be made of different materials and are not specifically limited. In a vertical orthographic projection, the frame 11b may be rectangular, circular, polygonal, etc., and is not specifically limited. The carrier 11a may be composed of a carrier plate, carrier sheet, carrier block, etc.
[0082] The entire top surface h1 of the main body 11 may be formed by the top surface of the carrier 11a, such that the entire frame 11b is located below the carrier 11a. The top surface h1 of the main body 11 may also be formed together with the top surface of the carrier 11a and the top surface of the frame 11b, in which case the carrier 11a is located inside the frame 11b, and the top surface of the carrier 11a and the top surface of the frame 11b may or may not be coplane.
[0083] The carrier 11a and frame 11b are fixedly connected or integrally molded. The carrier 11a and frame 11b are integrally molded by injection molding, die casting, forging, cold pressing, hot pressing, etc. The carrier 11a and frame 11b can be fixedly joined by fastening with fasteners, engaging with an engagement structure, welding, bonding, heat fusion bonding, etc.
[0084] The circumferential side walls n of the main body 11 are mainly formed from the circumferential side walls n of the frame 11b, and the circumferential side walls n of the frame 11b are the outer surfaces that are positioned around the carrier 11a and are away from the cavity that they define.
[0085] In some embodiments, referring to Figures 4 and 5, the body 11 further includes a bottom cover 11c that, together with the carrier 11a and frame 11b, surrounds a housing cavity s for housing a single battery unit 20.
[0086] The cavity of frame 11b penetrates to the bottom of frame 11b, and the bottom cover 11c covers the bottom of frame 11b, so together with frame 11b and carrier 11a it can be understood to form the housing cavity s of the housing 10.
[0087] Specifically, the bottom cover 11c may be a plate-like structure, a block-like structure, etc., but is not limited to these, and may be flat, curved, etc., and is not specifically limited. When the battery unit 20 is located in the housing cavity s, the battery unit 20 may be placed on the bottom cover 11c and / or the carrier 11a and / or the frame 11b.
[0088] The bottom cover 11c and the frame 11b can be fixed by welding, heat fusion, adhesive, fastening, locking, etc. Here, fastening connection refers to connection by fixing piece 11c4 including parts such as bolts, plugs, rivets, pins, and screws. Here, locking refers to being fixed by an engaging structure. For example, the bottom cover 11c has an engaging hook and the frame 11b has an engaging opening, and when the engaging hook engages with the engaging opening, the engaging and fixed connection between the bottom cover 11c and the frame 11b is achieved. Of course, the method of connecting the bottom cover 11c and the frame 11b is not limited to this and is not covered in this application.
[0089] In this case, the frame 11b can serve as the base, and the carrier 11a and bottom cover 11c can be connected to the vertical ends of the frame 11b, respectively, to form a cavity s for housing the battery 100. Such a structure of the main body 11 is relatively simple.
[0090] In some embodiments, referring to Figures 4 and 5, the bottom cover 11c has a cover portion 11c1 that defines the housing cavity s, a mounting portion 11c2 that is surrounded and connected to the edge of the cover portion 11c1, and a mounting portion 11c2 that is connected to the frame 11b.
[0091] The fact that the lid portion 11c1 defines the housing cavity s means that the lid portion 11c1, together with the carrier 11a and the frame 11b, surrounds and forms the housing cavity s, and the mounting portion 11c2 is connected to the frame 11b without being involved in defining the housing cavity s. The lid portion 11c1 may be a plate-shaped part, a block-shaped part, a flat plate-shaped part, a curved plate-shaped part, etc., and is not specifically limited. As can be seen from Figures 4 and 5, the fact that the mounting portion 11c2 is surrounded by the edge of the lid portion 11c1 means that the mounting portion 11c2 is connected along the edge of the lid portion 11c1 and the leading and trailing ends are closed together. Furthermore, the mounting portion 11c2 has a certain width in the vertical projection, which provides an appropriate contact area with the frame 11b, making it easy to position and attach the mounting portion 11c2 to the frame 11b.
[0092] The lid portion 11c1 and the mounting portion 11c2 may be integrally molded. If the bottom lid 11c is made of metal (e.g., aluminum, iron, stainless steel, etc.), the lid portion 11c1 and the mounting portion 11c2 can be integrally molded by die casting, forging, hot pressing, cold pressing, etc. If the bottom lid 11c is made of plastic (e.g., polypropylene, polyethylene, ABS (Acrylonitrile Butadiene Styrene Plastic)), the lid portion 11c1 and the mounting portion 11c2 can be integrally molded by injection molding. The lid portion 11c1 and the mounting portion 11c2 can also be molded separately and then connected. If the lid portion 11c1 and the mounting portion 11c2 are made of metal, the lid portion 11c1 and the mounting portion 11c2 may be welded or bonded together. If the lid portion 11c1 and the mounting portion 11c2 are made of plastic, the lid portion 11c1 and the mounting portion 11c2 may be bonded together. Of course, the lid portion 11c1 and the mounting portion 11c2 may be fixed and joined by other methods such as fastening or riveting.
[0093] The lid portion 11c1 and the mounting portion 11c2 may be located in the same plane. Specifically, optionally, both surfaces of the lid portion 11c1 and the mounting portion 11c2 facing the carrier 11a are in the same plane, and / or both surfaces of the lid portion 11c1 and the mounting portion 11c2 facing away from the carrier 11a are in the same plane. When both surfaces of the lid portion 11c1 and the mounting portion 11c2 facing the carrier 11a and both surfaces facing away from the carrier 11a are in the same plane, the lid portion 11c1 and the mounting portion 11c2 can form a single flat bottom lid 11c.
[0094] The lid portion 11c1 and the mounting portion 11c2 do not necessarily have to be located in the same plane. Specifically, the lid portion 11c1 may be recessed toward the carrier 11a relative to the mounting portion 11c2, or it may be projecting backward toward the carrier 11a relative to the mounting portion 11c2, but this is not specifically limited. The thickness of the lid portion 11c1 and the mounting portion 11c2 may be the same or different, and this is not specifically limited.
[0095] In this case, the bottom cover 11c defines the housing cavity s via the cover portion 11c1 and connects to the frame 11b via the mounting portion 11c2, so the structure is clear and installation is easy.
[0096] When the bottom cover 11c is detachably connected to the frame 11b, it can be understood that the bottom cover 11c is detachably connected to the frame 11b via the mounting portion 11c2, that is, the mounting portion 11c2 is detachably connected to the frame 11b. The method of detachably connecting the mounting portion 11c2 to the frame 11b only requires that the portion of the bottom cover 11c that is detachably connected to the frame 11b be designated as the mounting portion 11c2.
[0097] In some embodiments, the mounting portion 11c2 is detachably connected to the frame 11b.
[0098] Specifically, the bottom cover 11c is further provided with a fixing hole 11c3 in the mounting portion 11c2, and the fastener 11c4 is fastened to the frame 11b by passing through the fixing hole 11c3 of the mounting portion 11c2. The fixing hole 11c3 is a through hole that penetrates the mounting portion 11c2 vertically, and specifically, the fixing hole 11c3 may be a smooth through hole (for example, if the fastener 11c4 is a rivet), a through hole with screw threads (for example, if the fastener 11c4 is a screw), or a through hole of another type (hexagonal hole, square hole, wavy hole, etc.). The specific shape of the fixing hole 11c3 is determined by the specific shape and specific setting method of the fastener 11c4, and is omitted here.
[0099] In some embodiments, referring to Figures 6, 8, and 9, the housing 10 includes side beams 13 provided on the circumferential side walls n of the main body 11.
[0100] The side beam 13 is a beam structure provided on the circumferential side wall n of the main body 11 to reinforce the strength of the main body 11. The side beam 13 can be understood as being located outside the main body 11. Specifically, the main body 11 may be integrally connected to the side beam 13 to form a single unit, or it may be connected and formed a single unit by an assembly method. Integral connection methods include, but are not limited to, welding, integral molding, and fusion bonding. Assembly connection methods include, but are not limited to, locking and fastening connections.
[0101] The side beams 13 may be arranged around the entire circumferential side wall n of the main body 11, or they may be arranged around only a portion of the circumferential side wall n of the main body 11. Without limitation, by installing the side beams 13 around the circumferential side wall n of the main body 11, the strength of the main body 11 can be reinforced from multiple lateral directions. Specifically, the side beams 13 are provided continuously or intermittently around the circumferential side wall n of the main body 11. When installed continuously, the side beams 13 can form an annular beam, and when installed intermittently, they may include multiple beam sections spaced apart around the circumferential side wall n of the main body 11.
[0102] In some practical application scenarios, the housing 10 is used for the battery 100, the battery 100 is applied to the vehicle 1000, the top surface of the housing 10 is attached to the vehicle 1000, and the top surface of the housing 10 forms the chassis structure of the vehicle 1000. When the housing 10 of the battery 100 is used as the chassis of the vehicle 1000, the lateral structure of the housing 10 is susceptible to external impacts (for example, stones flying up while the vehicle 1000 is running hitting the lateral position of the housing 10, or collisions with other vehicles 1000 at the lateral position) and can be pushed out. In this case, a side beam 13 can be provided on the side periphery wall of the main body 11, thereby strengthening the lateral structural strength of the main body 11, further improving the lateral pressure resistance of the housing 10, and simultaneously improving the lateral pressure resistance of the vehicle 1000, thereby improving the safety of the vehicle 1000.
[0103] To make it clear, if the main body 11 includes the carrier 11a and frame 11b described above, the side beam 13 is installed on the circumferential side wall n defined by the frame 11b.
[0104] The cavity formed by the frame 11b mainly constitutes the housing cavity s of the housing 10, and since the housing cavity s has a certain height to accommodate multiple battery units 20, the frame 11b also has a certain height, and the area of the circumferential side wall n of the frame 11b is relatively large. In this case, the side beam 13 is installed on the circumferential side wall n defined by the frame 11b, and the mounting method, mounting area, and arrangement method of the side beam 13 are more flexible.
[0105] Furthermore, in this embodiment, the side beam 13 is fixedly connected to the frame 11b or integrally molded with it. The side beam 13 and the frame 11b may be fixedly joined by welding, fusion bonding, riveting, screw fastening, etc., or they may be integrally formed by integral processing (e.g., pressing, die casting, etc.).
[0106] If the side beams 13 and the frame 11b are integrally molded, the assembly process of the housing 10 can be reduced, and the manufacturing process of the housing 10 can be expedited. If the side beams 13 and the frame 11b are fixedly connected, the molding process of the side beams 13 and the frame 11b can be simplified, and the process cost of the housing 10 can be reduced.
[0107] In some embodiments, referring to Figure 10, the side beam 13 includes at least two sub-beams 13a that are sequentially spaced apart along the circumferential side wall n. The sub-beams 13a are the foundation units that make up the side beam 13, and by setting the position of the sub-beams 13a, the position of the side beam 13 can be flexibly positioned on the circumferential side wall n of the main body 11.
[0108] The side beam 13 is formed by installing at least two sub-beams 13a at intervals along the circumferential side wall n of the main body 11, meaning that at least two sub-beams 13a form a closed shape surrounding the main body 11 at intervals in the extending direction of the circumferential side wall n, thereby reinforcing the strength of the main body 11 from multiple lateral directions.
[0109] The structure of the sub-beam 13a can take multiple forms, and the structure of each sub-beam 13a may be the same or different. For example, a sub-beam 13a may be a solid beam extending in a single vertical direction, and for example, a sub-beam 13a may be a hollow beam extending in a single vertical direction. The cross-sectional shape of each sub-beam 13a can be an H-shape, a U-shape, or other structural shape.
[0110] In this case, since the side beam 13 is formed by combining multiple sub-beams 13a, the degree of freedom in arranging the side beam 13 is increased, and when installing, each sub-beam 13a only needs to be installed one by one, making positioning easier and more labor-saving compared to a single-piece side beam 13.
[0111] In some embodiments, continuing to refer to Figure 10, at least one sub-beam 13a includes an upper arm beam 131 and a lower arm beam 132, both connected to the main body 11 and spaced apart vertically.
[0112] The vertical direction corresponds to the direction in which the top and bottom of the main body 11 are located; that is, the upper arm beam 131 is close to the top surface of the main body 11, and the lower arm beam 132 is close to the bottom surface of the main body 11. Both the upper arm beam 131 and the lower arm beam 132 can be understood to extend in the circumferential direction of the main body 11 and be in close contact with the circumferential side wall n of the main body 11. The upper arm beam 131 and the lower arm beam 132 are spaced apart and connected via the main body 11, and a hole passage can be formed between them, which can serve both as a configuration for weight reduction and as a configuration for routing wire harnesses.
[0113] In this structure, where the main body 11 is reinforced by the upper arm beam 131 and the lower arm beam 132, the impact force received by the housing 10 can be distributed because the upper arm beam 131 and the lower arm beam 132 are positioned separately, and the external force received by various parts of the housing 10 can be made relatively uniform. At the same time, by positioning the upper arm beam 131 and the lower arm beam 132 with a vertical gap between them, the sub-beam 13a can withstand pressure from the vehicle 1000 in the front-rear or left-right direction, and is adapted to the actual usage conditions of the vehicle 1000. Furthermore, by positioning the upper arm beam 131 and the lower arm beam 132 with a gap between them, the housing 10 can be made lighter, and other functions can be realized.
[0114] In other embodiments, an intermediate beam (not shown) is provided between the upper arm beam 131 and the lower arm beam 132, and by connecting the intermediate beam between the upper arm beam 131 and the lower arm beam 132, the structural strength of the sub-beam 13a can be further enhanced, and the lateral pressure resistance of the housing 10 can be improved.
[0115] In some embodiments, at least one of the upper arm beam 131 and the lower arm beam 132 is a hollow beam. A hollow beam means that the inside of the beam is hollow, that is, there is a space inside the beam that is not filled with any solid material. In this case, since the upper arm beam 131 and the lower arm beam 132 are hollow beam structures, not only can their own weight be reduced, but when the battery 100 formed in the housing 10 is applied to a power consumption device such as a vehicle 1000, the problem of increased energy consumption of the battery 100 itself due to its weight can be reduced. In addition, the hollow beam structure can dissipate lateral pressure due to the space inside, and the degree of damage to the battery 100 when subjected to lateral pressure can be reduced.
[0116] In some embodiments, referring to Figure 6, the circumferential side wall n includes at least two spaced first wall segments n1 each extending along a first direction F1, and at least two sub-beams 13a include two first sub-beams 13a1 positioned on each of the two first wall segments n1 and both extending in the first direction F1.
[0117] In some practical applications, when a battery 100 formed in a housing 10 is used in a vehicle 1000, and the top surface of the housing 10 forms the chassis of the vehicle 1000, the first direction F1 can be made to correspond to the longitudinal direction of the vehicle 1000. The first wall segment n1 of the circumferential side walls n of the main body 11 corresponds to the circumferential side walls n on both the left and right sides of the battery 100. The first wall segment n1 extends in the first direction F1, i.e., the longitudinal direction of the vehicle 1000. The two first wall segments n1 are spaced apart in the 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.
[0118] The structure of the sub-beams 13a on each first wall segment n1 can be made identical, ensuring consistent pressure resistance on both the left and right sides of the vehicle 1000. Furthermore, the sub-beams 13a on the first wall segment n1 include the upper arm beam 131 and lower arm beam 132 described in the above embodiment. In this case, the high pressure resistance of the sub-beams 13a compensates for the weakness of the structure on both the left and right sides of the vehicle 1000, thereby strengthening the pressure resistance on both sides of the vehicle 1000 and improving the safety of the vehicle 1000.
[0119] In this case, by providing sub-beams 13a to each first wall segment n1, the structural strength of each first wall segment n1 can be strengthened, improving the pressing resistance of each first wall segment n1, i.e., the pressing resistance of the vehicle 1000 from side to side. Furthermore, since each sub-beam 13a extends in the first direction F1, it can be understood that the bending resistance of the vehicle 1000 in the longitudinal direction is also improved.
[0120] In some embodiments, referring to Figure 6, the circumferential side wall n further includes two second wall segments n2 spaced apart from each other, extending along a second direction F2 perpendicular to a first direction F1, and the two first wall segments n1 are staggeredly connected to the two second wall segments n2. At least two sub-beams 13a further include two second sub-beams 13a2, each positioned on the two second wall segments n2 and both extending in the first direction F1.
[0121] In practical applications, the second direction F2 can be made to correspond to the left-right direction of the housing 10. In this case, the second wall segment n2 corresponds to the circumferential side walls n in both the front-rear and rear directions of the battery 100. The second wall segment n2 extends in the second direction F2, i.e., the left-right direction of the vehicle 1000.
[0122] The structure of the sub-beams 13a on each second wall segment n2 can be made identical, ensuring consistent pressure resistance on both the front and rear sides of the vehicle 1000. Furthermore, the sub-beams 13a of the first wall segment n1 may include only the upper arm beams 131 described in the above embodiment, and the upper arm beams 131 are installed close to the top of the main body 11. In this case, the pressure resistance force of the sub-beams 13a is weak. This is because pressure resistance structures such as bumpers are generally provided in the front-rear direction of the vehicle 1000. When the vehicle 1000 is pressed in the front-rear direction, the pressure resistance effect is mainly achieved by the front and rear bumpers. In this case, the sub-beams 13a of the second wall segment n2 have a weak pressure resistance requirement, so a relatively simple sub-beam 13a structure can be adopted, reducing the cost of the battery 100 and the vehicle 1000.
[0123] In this case, by providing sub-beams 13a to each second wall segment n2, the structural strength of each second wall segment n2 can be strengthened, improving the pressing resistance of each second wall segment n2, i.e., the lateral pressing resistance of the vehicle 1000. Furthermore, since each sub-beam 13a extends in the second direction F2, it can be understood that the lateral bending resistance of the vehicle 1000 can also be improved.
[0124] In some embodiments, referring to Figure 6, the side beam 13 each includes at least two first sub-beams 13a1 and at least two second sub-beams 13a2 installed on the circumferential side wall n, the first sub-beams 13a1 extending along a first direction F1 and spaced apart from each other, and the second sub-beams 13a2 extending along a second direction F2 intersecting the first direction F1 and spaced apart from each other.
[0125] In this configuration, the sub-beam 13a provided on the first wall segment n1 is the first sub-beam 13a1, and the sub-beam 13a provided on the second wall segment n2 is the second sub-beam 13a2. The two first sub-beams 13a1 can reinforce the pressing resistance of the housing 10 in the left-right direction of the vehicle 1000, and the two second sub-beams 13a2 can reinforce the pressing resistance of the housing 10 in the front-rear direction of the vehicle 1000. As a result, the lateral pressing resistance of the vehicle 1000 can be improved overall, thereby improving the safety of the vehicle 1000.
[0126] In some embodiments, referring again to Figure 6, the top of the side beam 13 is configured to have a mounting portion 13a3.
[0127] A description of the mounting portion 13a3 can be found in the above description, so it will be omitted here. In this case, by providing the mounting portion 13a3 at the top of the side beam 13, the housing 10 of the embodiment of this application can be obtained by adding the side beam 13 based on the structure of the existing housing 10. This significantly reduces modification costs. On the other hand, by providing the mounting portion 13a3 on the side beam 13, the side beam 13 does not define the housing cavity s, so when providing the mounting portion 13a3, it is not necessary to consider the effect of the mounting portion 13a3 on the sealing performance of the housing cavity s, and the mounting portion 13a3 can be set more flexibly. In addition, since the side beam 13 is located on the side edge of the housing 10, providing the mounting portion 13a3 on the side beam 13 increases the operating space when attaching the housing 10 to an external device, making it more convenient.
[0128] In some embodiments, the mounting portion 13a3 includes at least one mounting hole k1 provided at the top of the side beam 13.
[0129] A description of the mounting hole k1 can be found in the above description, so it will be omitted here. The mounting hole k1 is located at the top of the side beam 13, and the mounting portion 13a3 is also located at the top of the side beam 13, which has the beneficial effect of being located at the top of the side beam 13, so it will be omitted here.
[0130] In some embodiments, the top surface h1 of the main body 11 is defined to form the top surface h of the housing 10 together with the top surface h2 of the side beam 13.
[0131] The top surface h1 of the main body 11 is the outer surface on one side of the main body 11 that is located at the top and away from the housing cavity s, and the top surface h2 of the side beam 13 is the outer surface on one side of the side beam 13 that is located at the top. If the side beam 13 includes the upper arm beam 131 and the lower arm beam 132 in the above embodiment, the top surface h2 of the side beam 13 is the outer surface on one side of the upper arm beam 131 that is away from the lower arm beam 132.
[0132] If the housing 10 includes both the main body 11 and the side beam 13 in the above embodiment, the top surface h of the housing 10 may be defined and formed together with the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. In this case, since the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can be arranged coplanely, the contact area between the top surface h of the housing 10 and the external device is increased, which can contribute to improving the reliability of the connection between the housing 10 and the external device, and the top surface structure of the housing 10 can be made relatively flat, improving its appearance. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 may not be coplane.
[0133] If the side beam 13 includes at least two sub-beams 13a, the top surface of each sub-beam 13a defines a portion of the top surface h2 that forms the side beam 13, and the sub-beams 13a are provided with mounting portions 13a3. Of these, mounting portions 13a3 may be provided on some of the sub-beams 13a, or on all of the sub-beams 13a. If mounting portions 13a3 are provided on some of the sub-beams 13a, mounting portions 13a3 are provided on all of the symmetrically installed sub-beams 13a in order to ensure uniformity of the load-bearing capacity of the mounting portions 13a3. The symmetrically installed sub-beams 13a include the two first sub-beams 13a1 in the above embodiment, but may also include the two second sub-beams 13a2 in the above embodiment.
[0134] In some embodiments, referring to Figures 6 and 10, the outer wall of the housing 10 is configured with a wire passage section 13a4 located below the top surface h of the housing 10, forming a wire passage space for passing a wire harness.
[0135] The outer wall of the housing 10 is an outer surface facing away from the inner surface that defines the housing cavity s within the housing 10. The cable routing section 13a4 is located below the top surface of the housing 10; that is, the cable routing section 13a4 is provided on the outer wall of the housing 10 located below the top surface h. The outer wall located below the top surface h of the housing 10 includes a bottom surface and side walls connecting the top surface h and the bottom surface.
[0136] If the housing 10 includes only the main body 11, the side walls of the housing 10 can be the circumferential side walls n of the main body 11. If the housing 10 includes the main body 11 and the side beams 13, the side walls of the housing 10 include the circumferential side walls n of the main body 11 that are not covered by the side beams 13, and the surface of the side beams 13 that are facing away from the main body 11.
[0137] The wiring section 13a4 is located outside the housing cavity s and has a wiring space through which a wire harness, which electrically connects the cell unit and the power consumption member, passes. The specific form of the wiring space is not limited and only needs to have a wire entry opening for the wire harness to enter and a wire exit opening for the wire harness to exit, and the entry and exit openings may be the same opening. The wiring space can be a wiring hole or a wiring groove k2.
[0138] Specifically, a wire passage 13a4 can be provided on the circumferential outer wall of the housing 10, in which case the wire harness can be routed via the side of the housing 10, making wiring easier. More specifically, a wire passage 13a4 can be provided on the bottom surface of the housing 10, in which case the wire harness can be routed via the bottom surface of the housing 10.
[0139] In this case, by forming a wire passage section 13a4 on the outer wall of the housing 10 and passing the wire harness through the wire passage space formed by the wire passage section 13a4, it is possible to effectively protect the wire harness by avoiding the wire harness being pressed and deformed when the vehicle 1000 is pressed from the outside, thereby preventing unnecessary safety hazards.
[0140] In yet another embodiment, referring again to Figures 6 and 10, the cable routing section 13a4 is located on a side wall adjacent to its own top surface h of the housing 10.
[0141] The side walls are the outer surfaces of the housing 10, connecting its top surface h to its bottom surface (the surface of the surface opposite to the top surface h). The wiring section 13a4 may be provided on only some of the side walls of the housing 10. For example, it may be provided on one or both side walls of the housing 10 in the first direction F1, or on one or both side walls of the housing 10 in the second direction F2. Of course, the wiring section 13a4 may be provided on all of the side walls of the housing 10.
[0142] In this case, the wiring section 13a4 is positioned on the side wall of the housing 10, and the lateral operating space of the housing 10 is increased, making it easier to arrange the wire harness.
[0143] In some embodiments, the cable routing section 13a4 is located on two side walls adjacent to the top surface h of the housing 10 and facing away from each other.
[0144] The two side walls adjacent to the top surface h of the housing 10 and facing away from each other include two side walls facing away from the first direction F1 and two side walls facing away from the second direction F2. In this case, the wire routing section 13a4 may be arranged symmetrically opposite to the first direction F1, or opposite to the second direction F2, and the wire harness may be routed simultaneously from both sides of the housing 10 in the first direction F1, or simultaneously from both sides of the housing 10 in the second direction F2, thereby achieving a symmetrical arrangement of the wire harness, which can result in a more aesthetically pleasing wiring arrangement and contribute to the balance of the vehicle weight 1000.
[0145] Furthermore, the wire routing section 13a4 is provided on both side walls of the housing 10 in the second direction F2, that is, on both side walls of the housing 10 corresponding to the left-right direction of the vehicle 1000. Since the various electric drive systems in the vehicle 1000 (which supply power for the forward movement of the vehicle 1000) are mainly located on the front or rear side, the wire harness mainly connects the battery 100 and the electric drive systems in the front-rear direction of the vehicle 1000, and by arranging the wire routing section 13a4 in this way, the routing of the wire harness can be made easier.
[0146] In one specific embodiment, referring to Figures 6 and 10, the cable routing section 13a4 includes a cable routing groove k2 formed in a concave shape toward the housing cavity s on the outer wall of the housing 10.
[0147] It can be understood that the cable routing groove k2 is recessed toward the housing cavity s, forming a cable routing space with one opening, and that the opening faces the bottom of the groove k2. The cable routing groove k2 is recessed toward the housing cavity s and may have an entry opening and an exit opening. Specifically, the entry opening of the cable routing groove k2 may be an opening at one end in the extending direction of the cable routing groove k2, and the exit opening of the cable routing groove k2 may be an opening at the other end in the extending direction of the cable routing groove k2.
[0148] The cable routing groove k2 can be provided extending in the first direction F1 when it is located on the side wall of the housing 10 in the second direction F2. The cable routing groove k2 can be provided extending in the second direction F2 when it is located on the side wall of the housing 10 in the first direction F1.
[0149] In this case, since the wire routing groove k2 has an opening, the installation of the opening makes it easier to pass the wire harness through. Furthermore, since the concave wire routing groove k2 is configured as a wire routing section 13a4, there is no need to add another structure to form a wire routing space, making the structure of the housing 10 simpler and less expensive.
[0150] Of course, in other embodiments, the cable routing section 13a4 may have a structure that includes a cable routing hole, such as a cable routing rod with a cable routing hole, which is additionally provided on the outer wall of the housing 10.
[0151] In some embodiments, referring to Figures 6 and 10, the side beam 13 is configured to form a wire passage 13a4.
[0152] Specifically, if the cable routing section 13a4 is the cable routing groove k2, the side beam 13 consists of the upper arm beam 131 and the lower arm beam 132 as in the above-described embodiment, and the space between the upper arm beam 131 and the lower arm beam 132 becomes the space where the cable routing groove k2 is located. Alternatively, the cable routing groove k2 is formed by recessing the side beam 13 at a distance from the outer surface of the main body 11.
[0153] If the cable passage section 13a4 is a cable passage hole, the side beam 13 can be made into a hollow beam that penetrates both ends in its extending direction, thereby configuring the internal space of the side beam 13 to form a cable passage hole. Alternatively, the side beam 13 includes the upper arm beam 131, lower arm beam 132, and intermediate beam (not shown) in the above-described embodiment, and the cable passage hole is surrounded by the intermediate beam, upper arm beam 131, and lower wall beam.
[0154] In this case, the cable passage section 13a4 is formed in the side beam 13, meaning that the side beam 13 is given a space for cable passage. This space for cable passage can reduce the weight of the side beam 13 and enable cable passage, killing two birds with one stone.
[0155] In one specific embodiment, both the upper arm beam 131 and the lower arm beam 132 are configured to form a wiring section 13a4 having a wiring space. In this case, the wiring space is formed by the space between the upper arm beam 131 and the lower arm beam 132, and the structure of the wiring section 13a4 is simple, killing two birds with one stone.
[0156] Figure 11 is a schematic diagram showing a partial structure of battery 100 in some other embodiments of this application, Figure 12 is an exploded side view of the structure shown in Figure 11, Figure 13 is a side view of the structure shown in Figure 11, and Figure 14 is an enlarged view of location D in the structure shown in Figure 12. Figure 15 is a schematic diagram showing an application scenario of the structure shown in Figure 11, and Figure 16 is a side view of the structure shown in Figure 14.
[0157] In some embodiments, referring to Figure 11, the housing 10 also includes a seal 12 located on the top of the body 10 for a sealed connection to an external device.
[0158] The seal 12 is a component that can prevent leakage of fluid or solid particles from adjacent bonding surfaces. The seal 12 is provided on the top of the housing 10, dividing the top of the housing 10 into an external region located on the outer circumference of the seal 12 and an internal region surrounded by the seal 12. The seal 12 seals and connects the two opposing surfaces of the top of the housing 10 and the external device, forming a contact interface between these two surfaces. This prevents fluid or solid particles from the external region on the outer circumference of the seal 12 from entering the internal region surrounded by the seal 12 through the contact interface between itself and the two surfaces, thereby providing a sealing effect.
[0159] The seal 12 is either a seal ring or a seal pad. Specifically, the seal 12 may be made of a material such as rubber or silica gel. Specifically, the seal 12 may be an O-shaped seal, a rectangular seal, an irregularly shaped seal, etc. The specific shape of the seal 12 can be adapted to the shape of the top surface of the housing 10 and two opposing surfaces of the external device. For example, if the top surface of the housing 10 and the two opposing surfaces of the external device are rectangular, the seal 12 may be a rectangular seal.
[0160] In this configuration, the battery housing 100 and the external device 12 are connected via a seal, ensuring a secure and low-cost connection.
[0161] The housing 10 of the battery 100 is sealed from the external device by the seal 12 and is fixedly connected to the external device by the mounting portion 13a3, and at this time it can be understood that the top surface h of the housing 10 is in contact with the external device.
[0162] Taking the example that the external device is the vehicle body 200 of the vehicle 1000, the battery 100 may be attached to the bottom of the vehicle body 200 and sealed to the vehicle body 200 by a seal 12 on the seal area HC. In this case, the internal area of the seal 12 is inside the vehicle body 200, and the external area is outside the vehicle body 200. Fluids or solid particles from outside the vehicle body 200 cannot leak into the vehicle body 200. For example, stones or liquids scattered while the vehicle 1000 is running cannot collide with the inside of the vehicle body 200, thereby achieving sealing performance and structural reliability inside the vehicle body 200.
[0163] In some embodiments, referring to Figures 7 and 11, a mounting position 141b is configured on the side of the housing 10 spaced apart from the housing cavity s at the top. Here, the battery 100 is attached to an external device via the top surface of the housing 10, and the mounting position 141b forms a substructure of the external device.
[0164] Mounting position 141b is a mounting area formed on a portion of the top surface of the housing 10 for attaching a fixing structure (hereinafter referred to as a mounting member). This mounting member can be a part of the structure of an external device, and mounting position 141b can be a structure such as a mounting bracket or mounting hole that has a connecting function. Taking the vehicle body 200 of the vehicle 1000 as an example, this mounting position 141b can be used to attach structures such as the seat 300 and operating levers of the vehicle 1000, and structures such as the seat 300 and operating levers are fixedly connected to mounting position 141b on the top of the box 10 via structures such as mounting brackets or mounting holes.
[0165] Specifically, the mounting material attached to the mounting position 141b may be a local structure of the external device. The mounting position 141b for attaching the local structure of the external device is connected to the external device at the top of the housing 10, and then forms a partial structure of the external device. At this time, the battery 100 is attached to the external device via the top of the housing 10, and after the mounting position 141b at the top of the battery 100 is formed as a local structure of the external device, the mounting material and the housing 10 of the battery 100 are connected to achieve connection with the external device.
[0166] In this way, by integrating the partial structures of the battery 100 and the external device, the partial structure of the battery 100's housing 10 can be made into a partial structure of the external device, thus avoiding the need for separate installation of the battery 100 and the external device.
[0167] In other embodiments, the mounting material attached to the mounting position 141b may be a structure other than an external device, and it is attached to the mounting position 141b to simultaneously achieve a fixed connection between the battery 100 and the external device.
[0168] In one specific embodiment, as shown in Figures 14 and 15, the external device is the vehicle body 200 of the vehicle 1000, and the mounting position 141b is used to mount the seat 300. By configuring the mounting position 141b on the top of the housing 10 of the battery 100, the internal structure of the vehicle body 200 is formed at the mounting position 141b, and the battery 100 and the vehicle body 200 are integrated into a single structure. This avoids the need for separate installation of the battery 100 and the vehicle body 200, simplifies the structure of the vehicle 1000, and makes it smaller and more compact.
[0169] The fixed connection of the housing 10, the vehicle body 200, and the seat 300 ensures that all structures are connected vertically to the top and bottom of the housing 10, reducing the mounting space and mounting load of the housing 10 in other directions, reducing the load on the lateral and bottom structures of the housing 10 of the battery 100, and improving the structural stability of the vehicle 1000.
[0170] In some embodiments, referring to Figure 7, the mounting position 141b includes a mounting hole located at the top of the housing 10.
[0171] The mounting hole is a through-hole that penetrates vertically through the mounting position 141b. When attaching the mounting sheet 300, etc., to the mounting position 141b, it is necessary to install fasteners. The mounting hole may be a smooth through-hole (for example, a rivet), a through-hole with threads (for example, a screw), or a through-hole of another type (hexagonal hole, square hole, wavy hole, etc.). The specific shape of the fixing hole 11c3 is determined by the specific shape and setting method of the fastener and is omitted here.
[0172] The number of mounting holes is the same as the number of fasteners, and one fastener is installed as a set in each mounting hole. The corresponding mounting material is then attached and positioned within the mounting hole by the fastener, thereby achieving both the fixing of the mounting material to the housing 10 of the battery 100 and, at the same time, a fixed connection between the mounting material and the external device.
[0173] In other embodiments, the mounting position 141b is not particularly limited and may include other structures such as metal fittings or elastic locks configured on the top of the housing 10.
[0174] In some embodiments, referring to Figures 4 to 7 and Figure 11, the housing 10 includes a main body 11 that surrounds and forms a housing cavity s, and a mounting beam 141, the top of the main body 11 forming at least a portion of the top of the housing 10. The mounting beam 141 is provided on the top of the main body 11, and a mounting position 141b is configured on the side spaced apart from the main body 11.
[0175] The main body 11 may be a single-piece molded structure, or it may be formed by combining multiple parts. The specific configuration format has been explained in detail above, so it will not be explained here.
[0176] One side of the housing 10 that is spaced apart from the housing cavity s at the top has a top surface h, and the mounting position 141b and the top surface h are in communication with each other. The mounting beam 141 is a structure with a certain load-bearing capacity provided on one side of the top of the main body 11 to share the biasing force from the mounting material that the top of the housing 10 receives. As shown in Figures 15 and 16, when the mounting material is a sheet 300, when a worker sits on the sheet 300, pressure is applied, and this pressure first acts on the mounting beam 141 and then on the top of the housing 10.
[0177] The mounting beam 141 may be provided directly on the surface of the top surface h, or on the uneven surface formed on the top surface h. One or more load-bearing structures included in the mounting beam 141 are configured to form mounting positions 141b for fixing mounting members on one side spaced apart from the top surface h, thereby realizing a connection between the mounting member and the top of the housing 10.
[0178] Depending on the size, weight, and specific structure of the mounting material that needs to be attached to the mounting position 141b, the installation form and extension direction of the load-bearing structure are set, and are not specifically limited, so that the force acting on the top of the main body 11 is shared by the mounting beam 141, thereby improving the load-bearing capacity of the battery 100 housing 10.
[0179] In some embodiments, the mounting beam 141 is fixedly connected to the main body 11 or is molded integrally with it.
[0180] The mounting beam 141 and the main body 11 can be permanently joined by fastening devices, engaging structures, welding, bonding, heat fusion, etc. Of course, the mounting beam 141 and the main body 11 may also be integrally formed by injection molding, die casting, forging, cold pressing, hot pressing, etc.
[0181] If the main body 11 is made of metal (e.g., aluminum, iron, stainless steel, etc.), the mounting beam 141 and the main body 11 can be integrally molded by die casting, forging, hot pressing, cold pressing, etc. If the main body 11 is made of plastic (e.g., PP, PE, ABS, etc.), the mounting beam 141 and the main body 11 can be integrally molded by injection molding. The mounting beam 141 and the main body 11 can also be molded separately and then connected. If the mounting beam 141 and the main body 11 are made of metal, the mounting beam 141 and the main body 11 may be welded or bonded together. If the mounting beam 141 and the main body 11 are made of plastic, the mounting beam 141 and the main body 11 may be bonded together.
[0182] By permanently connecting the mounting beam 141 and the main body 11, the molding process for the mounting beam 141 and the main body 11 becomes easier, and the manufacturing cost of the housing 10 can be reduced.
[0183] By integrally molding the mounting beam 141 with the main body 11, the assembly of the housing 10, external devices, and mounting materials becomes easier.
[0184] In other embodiments, the main body 11 may be connected to a part other than the mounting beam 141, and the connection method may be integral molding or fixed connection. The embodiment is not specifically limited.
[0185] In some embodiments, referring to Figures 7 and 11, the mounting beam 141 includes at least one protrusion 141a, each protrusion 141a projecting from the top of the body 11 in a direction away from the housing cavity s, each protrusion 141a together with the body 11 to form a weight reduction passage 141a1, and the mounting position 141b is configured on one side where the protrusion 141a faces away from the body 11.
[0186] The protrusion 141a is a load-bearing structure included in the mounting beam 141 described above, and is provided projecting in a direction away from the housing cavity s, opposite to the plane on which the top surface h of the housing 10 is located. The protrusion 141a itself has a certain height and is provided to protrude relative to the top surface h of the housing 10. At the mounting position 141b, all the protrusions 141a are formed on one side away from the main body 11. In this case, when the mounting material is attached to the mounting position 141b, it does not directly contact the top surface h but directly contacts the structure of the protrusions 141a, so the force received on the top surface of the housing 10 by the protrusions 141a is distributed, and the load-bearing capacity of the top of the housing 10 is increased.
[0187] Each protrusion 141a can have a structure that is open on multiple sides with one end as the center, and the top surface h1 of the main body 11 is covered by the open openings of each protrusion 141a, together forming a weight reduction passage 141a1. The weight reduction passage 141a1 can be formed by making the inside of the protrusion 141a hollow, or by carving holes or grooves, thereby reducing the weight of the housing 10.
[0188] In one specific embodiment, a weight-reducing passage 141a1 is provided inside each protrusion 141a, extending through it in its own direction of extension. The installation of this weight-reducing passage 141a1 reduces the weight of each protrusion 141a, thereby reducing the overall weight of the housing 10 and lowering costs. Each of the weight-reducing passages 141a1 that extend through the housing can form a hidden passage, and in other embodiments, operations such as the placement of dark lines can be performed through these hidden passages.
[0189] In some embodiments, as can be seen in Figures 6 and 7, all the protrusions 141a extend in the same direction and are spaced apart from one another.
[0190] The direction referred to as "same direction" may specifically be the first direction F1 or the second direction F2 described above, or it may be a direction that is coplane with and intersects the first direction F1 and the second direction F2, and is not specifically limited.
[0191] The fact that all the protrusions 141a are spaced apart from each other means that, in a direction intersecting the extending direction of the protrusions 141a, a set interval is maintained between each pair of adjacent protrusions 141a. Under the influence of this set interval, a buffer space is formed between each pair of adjacent protrusions 141a, preventing external forces acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the multiple spaced-apart protrusions 141a can form a sufficient support area and fixing position, enabling the support of the mounting material over a large area and making it applicable to mounting materials of different volumes and sizes.
[0192] Since all the protrusions 141a are arranged parallel to each other in the same direction, the buffer space extends in the same direction as the protrusions 141a, and in practical applications, buffering can be achieved at any position in the extending direction of the mounting beam 141.
[0193] The set spacing between each pair of adjacent protrusions 141a may be equal or uneven, and it can be understood that the set spacing between each pair of adjacent protrusions 141a is equal in order to ensure uniform support of the mounting material.
[0194] In some embodiments, all of the protrusions 141a are located on the same plane on one side facing away from the main body 11.
[0195] By positioning all the protrusions 141a so that they protrude in the same direction and making the protrusion height of all the protrusions 141a the same, one side of all the protrusions 141a that is spaced away from the mounting cavity forms a flat plane in a certain direction on a horizontal plane, allowing the mounting material to be placed on the flat plane and mounted more smoothly and simply, and moreover, a strong connection between the mounting material and the mounting beam 141 can be achieved.
[0196] In one specific embodiment, the protrusion 141a can be a rectangular prism-shaped structure, and all the same sides of the protrusion 141a are on the same plane, and together they define and form mounting positions 141b for attaching the mounting material, so that the mounting material can be smoothly placed on the mounting beam 141.
[0197] In some embodiments, referring to Figures 4, 7, and 11, the housing 10 further includes side projection reinforcing beams 14 installed on the top of the main body 11 and extending from the middle of the top of the main body 11 toward the opposing outer edges on both sides of the top of the main body 11.
[0198] The side-projection reinforcing beam 14 is a beam structure installed at the top of the main body 11 to reinforce the strength of the main body 11. The side-projection reinforcing beam 14 can be understood as being located on the outside of the main body 11. Specifically, the main body 11 may be integrally connected to the side-projection reinforcing beam 14 to form a single unit, or it may be integrally connected by assembly. Integral connection includes, but is not limited to, welding, integral molding, fusion bonding, etc. Assembly connection includes, but is not limited to, locking, screw connection, etc.
[0199] The side impact reinforcing beam 14 may extend from the middle of the top of the main body 11 toward the opposing outer edges on both sides of the top of the main body 11 in the first direction F1, in which case the side impact reinforcing beam 14 can reinforce the side impact prevention capability of the housing 10 in the first direction F1. The side impact reinforcing beam 14 may extend from the middle of the top of the main body 11 toward the opposing outer edges on both sides of the top of the main body 11 in the second direction F2, in which case the side impact reinforcing beam 14 can reinforce the side impact prevention capability of the housing 10 in the second direction F2.
[0200] The side-projecting reinforcing beams 14 may extend in two directions along the same straight line from the center of the top of the main body 11 toward the opposing outer edges on both sides of the top of the main body 11, or they may extend in two directions intersecting each other toward the opposing outer edges on both sides of the top of the main body 11. When the side-projecting reinforcing beams 14 extend in two directions along the same straight line from the center of the top of the main body 11 toward the opposing outer edges on both sides, the side-projecting reinforcing beams 14 can be realized by a single straight beam, making the structure simpler.
[0201] The side-projecting reinforcing beam 14 may extend to the outer edges on both sides, to the area between the outer edges on both sides and the middle part, or to an area beyond the outer edges on both sides. In other words, as long as it extends from the middle part of the top of the main body 11 toward the opposing outer edges on both sides of the top of the main body 11, the specific length of the side-projecting reinforcing beam 14 is not limited.
[0202] When the battery 100 is applied to the vehicle 1000 and the top of the housing 10 is configured as the chassis of the vehicle 1000, the vehicle 1000 has poor side impact resistance in the lateral direction. Therefore, the side impact reinforcing beam 14 can be designed to extend from the middle of the top of the main body 11 toward the outer edges on both sides of the top of the main body 11 in the lateral direction of the vehicle 1000, thereby strengthening the side impact resistance of the vehicle 1000 in the lateral direction and improving the safety of the vehicle 1000.
[0203] In this case, by providing a side impact reinforcing beam 14 at the top of the main body 11 of the housing 10, the side impact prevention capability of the housing 10 can be improved, and furthermore, the side impact prevention capability of the vehicle 1000 equipped with the battery 100 made of this housing 10 can be improved, thereby contributing to the assurance of the safety of the battery 100 and the vehicle 1000.
[0204] If the main body 11 includes a frame 11b and a carrier 11a, a side-projection reinforcing beam 14 is provided at least on the top of the carrier 11a. In this case, since the top of the carrier 11a forms at least a part of the top of the main body 11, there is sufficient space on the carrier 11a for attaching the side-projection reinforcing beam 14.
[0205] In some embodiments, the side-projecting reinforcing beam 14 extends to connect to the top of the frame 11b.
[0206] In this case, the top of the frame 11b also forms part of the top of the main body 11, and the side-projecting reinforcing beam 14 can extend to connect with the top of the frame 11b. In addition to directly connecting the frame 11b and the carrier 11a, the connection can be strengthened by the side-projecting reinforcing beam 14, thereby improving the reliability of the connection between the frame 11b and the carrier 11a.
[0207] In some embodiments, there is at least one side-projection reinforcing beam 14, all of which extend in the same direction and are spaced apart from one another.
[0208] The direction referred to as "same direction" may specifically be the first direction F1 or the second direction F2 described above, or it may be a direction that is coplane with and intersects the first direction F1 and the second direction F2, and is not specifically limited.
[0209] All side impact reinforcing beams 14 extend in the same direction, and each side impact reinforcing beam 14 can reinforce the side impact prevention capability of the housing 10 in the direction of extension, thereby strengthening the side impact prevention capability of the housing 10 in that direction of extension. Each side impact reinforcing beam 14 is spaced apart in a direction intersecting this "same direction," and it can be understood that by installing them in this way, the strength at multiple locations of the housing 10 can be reinforced so that the structural strength and side impact prevention capability of the housing 10 become more uniform.
[0210] In some embodiments, at least one of the side-projecting reinforcing beams 14 is configured as a mounting beam 141 with an attachment position 141b on one side spaced apart from the main body 11.
[0211] The mounting beam 141 and mounting position 141b are described in detail above and are omitted here. If there is one side-projection reinforcing beam 14, this side-projection reinforcing beam 14 shall be the mounting beam 141. If there are at least two side-projection reinforcing beams 14, a portion of them may be the mounting beam 141. Specifically, if there are at least two side-projection reinforcing beams 14, the side-projection reinforcing beam 14 closer to the front of the vehicle 1000 may be used as the mounting beam 141 for attaching the seat 300 (the seat 300 may also be the seat 300 inside the driver's cab).
[0212] In this case, by making at least one of the side impact reinforcing beams 14 the mounting beam 141, it is not only possible to prevent side impacts, but it is also possible to attach other mounting members, thus allowing for dual use.
[0213] In some embodiments, the side-projecting reinforcing beam 14 includes at least one projection 141a, each projection 141a projecting from the top of the main body 11 in a direction away from the housing cavity s, and each projection 141a together with the main body 11 forms a weight-reducing passage 141a1.
[0214] The protrusion 141a of the side-projecting reinforcing beam 14 has the same configuration as the protrusion 141a when the structure of the mounting beam 141 was described in the above embodiment, and the above description can be used for specific details. The protrusion 141a is provided projecting in a direction away from the housing cavity s, opposite to the plane on which the top surface h1 of the main body 11 is located, and the protrusion 141a itself has a certain height and is provided to project relative to the top surface h1 of the main body 11.
[0215] Each protrusion 141a can have a structure that is open on multiple sides with one end as the center, and the top surface h1 of the main body 11 is covered by the open openings of each protrusion 141a, together forming a weight reduction passage 141a1. The weight reduction passage 141a1 can be formed by making the inside of the protrusion 141a hollow, or by carving holes or grooves, thereby reducing the weight of the housing 10.
[0216] In one specific embodiment, a weight-reducing passage 141a1 is provided inside each protrusion 141a, extending through it in its own direction of extension. The installation of this weight-reducing passage 141a1 reduces the weight of each protrusion 141a, thereby reducing the overall weight of the housing 10 and lowering costs. Each of the weight-reducing passages 141a1 that extend through the protrusion can form a hidden passage, and in other embodiments, operations such as the placement of dark lines can be performed through these hidden passages.
[0217] In some embodiments, as shown in Figure 7, all the protrusions 141a extend in the same direction and are spaced apart from one another.
[0218] The fact that all the protrusions 141a are spaced apart from each other means that, in a direction intersecting the extending direction of the protrusions 141a, a set interval is maintained between each pair of adjacent protrusions 141a. Under the influence of this set interval, a buffer space is formed between each pair of adjacent protrusions 141a, preventing external forces acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the multiple spaced-apart protrusions 141a can form a sufficient support area and fixing position, enabling the support of the mounting material over a large area and making it applicable to mounting materials of different volumes and sizes.
[0219] Since all the protrusions 141a are arranged parallel to each other in the same direction, the buffer space extends in the same direction as the protrusions 141a, and in practical applications, buffering can be achieved at any position in the extending direction of the side-projection reinforcing beam 14.
[0220] The set spacing between each pair of adjacent protrusions 141a may be equal or unequal. When the side-projection reinforcing beam 14 is used as the mounting beam 141, it can be understood that the set spacing between each pair of adjacent protrusions 141a is equal in order to ensure uniform support of the mounting material.
[0221] In some embodiments, all of the protrusions 141a are located on the same plane on one side facing away from the main body 11.
[0222] All of the protrusions 141a are located on the top surface h1 of the main body 11, and all of the protrusions 141a are installed in a convex shape facing the same direction, and the height of the protrusions is set to be the same, so that all of the protrusions 141a form a flat surface on a horizontal plane, a flat surface in a direction on one side away from the mounting cavity is formed, and a strong connection between the mounting material and the mounting beam 141 is achieved.
[0223] In one specific embodiment, the protrusion 141a can be a rectangular prism-shaped structure, and all the same sides of the protrusion 141a are on the same plane, and together they define and form mounting positions 141b for attaching the mounting material, so that the mounting material can be smoothly placed on the mounting beam 141.
[0224] In some embodiments, as shown in Figure 10, the housing 10 is formed with a battery cavity s1 for housing a single battery 20 and a high-voltage cavity s2 for housing a high-voltage case, which are provided independently of each other.
[0225] The high-voltage case is a critical safety barrier for the battery 100 set, and it is equipped with a high-voltage control system and is mainly used for the following: turning the high-voltage circuit on or off according to the electronic control requirements of the entire vehicle, providing current and leakage detection terminals, enabling controllable tape carrier interruption when the external current of the battery 100 set becomes excessive, and enabling the high-voltage circuit to be interrupted when the external line of the battery 100 set is short-circuited, thereby preventing the battery 100 set from igniting, and allowing the high-voltage circuit to be easily interrupted when the battery 100 set is being repaired.
[0226] The fact that the battery cavity s1 and the high-voltage cavity s2 are provided independently of each other means that the battery cavity s1 and the high-voltage cavity s2 are sealed to each other. In order to provide the battery cavity s1 and the high-voltage cavity s2 independently, it is possible to form the battery cavity s1 and the high-voltage cavity s2 separately with two independent parts. For example, an independent first part and a second part are provided inside the housing 10, with the first part forming the battery cavity s1 and the second part forming the high-voltage cavity s2. Alternatively, a partition material is provided inside the housing 10 to divide the housing cavity s formed inside the housing 10 into an independent battery cavity s1 and a high-voltage cavity s2. Alternatively, the entire housing cavity s formed inside the housing 10 is made into the battery cavity s1, and a high-voltage chamber 15 is formed outside the housing 10 to form the high-voltage cavity s2, thereby making the battery cavity s1 and the high-voltage cavity s2 independent of each other.
[0227] The battery cavity s1 is for housing a single battery unit 20, and the high-voltage cavity s2 is for housing a high-voltage case. If the battery cavity s1 is provided independently of the high-voltage cavity s2, high-temperature gas leaking due to thermal failure of the single battery unit 20 in the battery cavity s1 will not enter the high-voltage case, and furthermore, it will not cause thermal damage to the high-voltage control system in the high-voltage case, thus ensuring the normal control function of the high-voltage control system and improving the safety performance of the battery 100.
[0228] In some embodiments, referring to Figures 11 to 13, the housing 10 further includes a high-voltage chamber 15, where a battery cavity s1 is formed within the main body 11, and the high-voltage chamber 15 is located outside the main body 11 and surrounds the high-voltage cavity s2 either by itself or together with the main body 11.
[0229] The high-pressure chamber 15 can be the structure of the housing 22, and its interior is hollow to form the high-pressure chamber 15, which is for placing the high-pressure case. By providing the high-pressure chamber 15 outside the main body 11 and forming the battery cavity s1 with the main body 11 (in this case, the battery cavity s1 corresponds to the housing cavity s), the high-pressure cavity s2 and the battery cavity s1 can be provided independently.
[0230] When the high-pressure chamber 15 forms a high-pressure cavity s2 together with the main body 11, the high-pressure chamber 15 has one opening, through which it is attached to the main body 11. When the high-pressure chamber 15 itself surrounds the high-pressure cavity s2, only an attachment relationship exists between it and the main body 11.
[0231] At this time, a high-voltage cavity s2 is defined and formed by the high-voltage chamber 15 provided outside the main body 11, and the housing cavity s formed by the main body 11 can be used as a battery housing cavity s1 to house a single battery 20, thereby improving the electrical capacity of the battery 100.
[0232] In some embodiments, referring to Figures 11 and 12, the high-pressure chamber 15 is positioned protruding from the top of the main body 11.
[0233] The high-voltage chamber 15 is located on the top of the main body 11, on the outside of the main body 11, and installed on the top surface h1 of the main body 11. When the battery housing 100 is used as the chassis of the vehicle 1000, the high-voltage chamber 15 is located on the top of the main body 11, so it is not exposed to the outside of the vehicle 1000 and is protected from external impacts (such as stones that fly up while the vehicle 1000 is running), making the high-voltage chamber 15 safer.
[0234] If the main body 11 includes the frame 11b and the carrier 11a, the carrier 11a constitutes at least a portion of the top of the main body 11, and the high-pressure chamber 15 is installed on the top of the carrier 11a, and can be understood to surround itself or together with the carrier 11a to form a high-pressure cavity s2. In this case, since the carrier 11a constitutes most of the top of the main body 11, installing the high-pressure chamber 15 on the top of the carrier 11a widens the mounting space for the high-pressure chamber 15, making the mounting more stable.
[0235] Of course, if the top of the frame 11b is also configured as part of the top of the main body 11, the high-pressure chamber 15 may also be provided on the top of the frame 11b, and may be specifically set according to the mounting method between the frame 11b and the carrier 11a.
[0236] In some embodiments, as shown in Figures 11 to 13, the high-pressure chamber 15 is installed close to the top outer edge of the main body 11.
[0237] The top outer edge of the vehicle body 11 includes the following: the top of the vehicle body 11 is installed on one outer edge in the forward direction of the vehicle 1000; the top of the vehicle body 11 is installed on one outer edge in the rear direction of the vehicle 1000; the top of the vehicle body 11 is installed on one outer edge in the left direction of the vehicle 1000; and the top of the vehicle body 11 is installed on one outer edge in the right direction of the vehicle 1000.
[0238] In one practical example, the high-pressure chamber 15 is positioned such that its top, near the main body 11, is located on one outer edge in the rearward direction of the vehicle 1000. In other words, the high-pressure chamber 15 is positioned close to the rear of the vehicle 1000. In this case, the high-pressure chamber 15 can be positioned in accordance with the passenger space behind the driver's space of the vehicle 1000, and in particular, it can be positioned below the seats 300 in the passenger space, without occupying the activity space of the vehicle 1000.
[0239] In some embodiments, referring to Figures 4, 6, and 11-13, the high-pressure chamber 15 is arranged sequentially in a first direction F1 with respect to the side-projection reinforcing beams 14, and the side-projection reinforcing beams 14 extend in a second direction F2 that intersects with the first direction F1.
[0240] If the housing 10 includes a side-projection reinforcing beam 14, both the high-pressure chamber 15 and the side-projection reinforcing beam 14 may be provided at the top of the main body 11.
[0241] The fact that the high-pressure chamber 15 and the lateral reinforcing beams 14 are sequentially arranged in the first direction F1 means that the high-pressure chamber 15 is located on one side of all the lateral reinforcing beams 14 in the first direction F1. Furthermore, the lateral reinforcing beams 14 extend in the second direction F2, which intersects the first direction F1, without interfering with the high-pressure chamber 15. This results in a rational structural arrangement of the high-pressure chamber 15 and the lateral reinforcing beams 14, and a high utilization rate of the top space of the main body 11.
[0242] In a specific embodiment, referring to Figure 4, the high-pressure chamber 15 includes a chamber lid 15a and a chamber case 15b provided at the top of the main body 11, with a high-pressure cavity s2 formed therein, spaced apart from the main body 11 and open. The chamber lid 15a detachably covers one open side of the high-pressure cavity s2.
[0243] The connection between the chamber case 15b and the main body 11 may be made by welding, fusion bonding, adhesive bonding, fastening, etc. The chamber case 15b may be made of plastic, but is not limited to this. The connection between the chamber lid 15a and the chamber case 15b may be detachably connected by fasteners or by locking, and the specific form is not limited.
[0244] In this configuration, the chamber case 15b forms a high-pressure cavity s2, the chamber lid 15a seals the high-pressure cavity s2, and the chamber lid 15a and the chamber case 15b are detachably connected, making it easy to install and repair the high-pressure case.
[0245] Figure 17 is a schematic diagram showing a part of the structure of battery 100 in some other embodiments of this application, Figure 18 is a side view of the structure shown in Figure 17, Figure 19 is an exploded view of the structure shown in Figure 18, and Figure 20 is a cross-sectional view of the EE area in the structure shown in Figure 18. Figure 21 is a plan view of the structure shown in Figure 17.
[0246] In some embodiments, referring to Figures 17 to 21, the housing 10 further includes a central passage beam 16 that extends from the top of the main body 11 along a first direction F1 and is positioned equidistant from the outer edges on both sides of the top of the main body 11 in a second direction F2 intersecting the first direction F1, and has a wire passage 16a for passing a wire harness through.
[0247] In conventional vehicles 1000, a central passage beam 16 is generally provided on the chassis of the vehicle body 200. The central passage beam 16 is a beam structure that extends from the front chassis to the rear chassis of the vehicle body 200 and is a major structural member that ensures the collision transmission path of the vehicle body 200 and the rigidity of the bottom plate of the vehicle body 200. The central passage beam 16 is located in the intermediate region of the vehicle chassis 1000 and extends along the longitudinal direction of the vehicle 1000 from the front chassis to the rear chassis.
[0248] In this embodiment, the central aisle beam 16 of the vehicle 1000 is directly integrated into the top of the main body 11 of the housing 10. Specifically, the central aisle beam 16 extends in a first direction F1 (corresponding to the longitudinal direction of the vehicle body 200) and is installed at equidistant from both outer edges of the top of the vehicle body 11 in a second direction F2 (corresponding to the left-right direction of the vehicle body 200), and is positioned in the central region of the top of the vehicle body 11.
[0249] Generally, to reduce the weight of the vehicle body 200 and lighten the vehicle body 200, the central passage beam 16 is made into a hollow structure. In this embodiment, by utilizing the hollow structure provided inside the central passage beam 16 to form a wire passage 16a for passing wire harnesses, weight reduction can be achieved, and the arrangement of wire harnesses can be realized, allowing for more flexible and safer arrangement of wire harnesses.
[0250] The intermediate passage beam 16 may be a sheet metal member integrally formed by pressing, die casting, etc., or it may be a beam structure formed by welding, fusion, or fastening multiple sheet metal plates, as long as it can form the passage 16a of the cable route. The passage 16a may be located inside the intermediate passage beam 16 (for example, in a hole passage inside the intermediate passage beam 16) or outside the intermediate passage beam 16 (for example, in a recessed groove passage outside the intermediate passage beam 16). The intermediate passage beam 16 may form the passage 16a together with the main body 11, or it may form the passage 16a by itself. The intermediate passage beam 16 and the main body 11 can be connected and integrated by welding, fusion, fastening, etc.
[0251] The wire passage 16a provided in the intermediate passage beam 16 may extend along the direction of extension of the intermediate passage beam 16 (i.e., the first direction F1), or it may be designed according to other needs as long as it allows for wire passage. The intermediate passage beam 16 can be provided with multiple independent wire passages 16a, allowing for the separate passage of different types of wire harnesses, and facilitating installation and maintenance.
[0252] In this case, if the top of the housing 10 is configured as the chassis of the vehicle body 200 of the vehicle 1000 (the chassis which is the floor of the vehicle body 200), there is no need to provide an additional intermediate passage beam 16, and the assembly workability of the vehicle body 200 is improved. On the other hand, by utilizing the hollow structure formed inside the intermediate passage beam 16 to form a wire passage 16a for passing wire harnesses, weight reduction can be achieved, the arrangement of wire harnesses can be realized, and the routing of wire harnesses can be made more flexible.
[0253] In some embodiments, referring to Figure 20, the central passage beam 16 is provided at the top of the main body 11 and includes a beam base 161 in which a line passage groove 16a1 is formed as a line passage 16a, the line passage groove 16a1 is recessed toward the housing cavity s.
[0254] The beam base 161 is directly attached to the main body 11, and is fixed to the main body 11 by methods such as welding, fusion bonding, or fastening. The beam base 161 has a wire passage groove 16a1 that is recessed toward the housing cavity s, that is, the wire passage groove 16a1 has a notch that is spaced apart from the housing cavity s, and this notch facilitates the insertion of the wire harness.
[0255] The wire passage groove 16a1 may be a continuous groove structure formed by recessing the beam base 161 on one side of the surface spaced apart from the housing cavity s, or it may be a plurality of wire passage sections having grooves recessed toward the housing cavity, formed on one side of the beam base 161 spaced apart from the housing cavity s, with each wire passage section being spaced apart in the setting direction, and all the recessed grooves of the wire passage sections together form the wire passage groove 16a1 of the beam base 161.
[0256] At this time, the beam base 161 forms a recessed wire passage groove 16a1 toward the housing cavity s, making it easy to attach the wire harness.
[0257] In some embodiments, as shown in Figure 20, there are multiple line passage grooves 16a1, all of which extend in the same direction and are spaced apart from one another.
[0258] Multiple wire passage grooves 16a1 are provided, and these multiple wire passage grooves 16a1 can extend at intervals in the same direction (for example, the first direction F1). Each wire passage groove 16a1 can accommodate one type of wire harness (the type of wire harness can be classified according to the type to which it is connected, for example, a wire harness connected to an air conditioner, a wire harness connected to a vehicle light, a wire harness connected to a power drive system, etc.).
[0259] This allows different types of wire harnesses to be placed independently, making the installation and maintenance of wire harnesses easier.
[0260] In some embodiments, the wire passage groove 16a1 is configured to engage with a wire harness passing through it.
[0261] Specifically, in order to secure the wire harness in the wire passage groove 16a1, the notch size of the wire passage groove 16a1 can be made equal to the diameter of the wire harness through which it is inserted, or the two can be secured by interlocking them. Specifically, a fastening member can be provided in the notch of the wire passage groove 16a1, one end of the fastening member can be rotatably connected to one side of the notch of the wire passage groove 16a1, and the other end can be detachably fastened to the other side of the notch of the wire passage groove 16a1, and after the wire harness is placed in the wire passage groove 16a1, the fastening member can be fastened to the notch of the wire passage groove 16a1, thereby securing the wire harness inside the wire passage groove 16a1.
[0262] This makes it possible to avoid noise caused by the wobbling of the wire harness, and also avoids the problem of the wire harness being damaged by coming out of the wire passage groove 16a1.
[0263] In some embodiments, referring to Figure 20, the central passage beam 16 further includes a beam cover 162 that is detachably covered on the opening side of the line passage groove 16a1.
[0264] The opening side of the line passage groove 16a1 is the side where the notch of the line passage groove 16a1 exists. The beam cover 162 is detachably covered on the opening side of the line passage groove 16a1, that is, detachably connected to the beam base 161. Specifically, the beam cover 162 is detachably engaged with the beam base 161, or the beam cover 162 and the beam base 161 are detachably connected by fasteners (e.g., bolts). The method for achieving the detachable connection between the beam cover 162 and the beam base 161 can adopt common settings in the art, and it is not necessary to limit the description here.
[0265] In this case, by covering the notch of the wire passage groove 16a1 with the beam cover 162, external ash and moisture can be prevented from entering the wire passage groove 16a1 and corroding the wire harness, and the wire harness can be protected from crushing failure due to external force, thereby improving the safety of the battery 100.
[0266] In some embodiments, the high-voltage cavity s2 is in communication with the wiring passage 16a.
[0267] Generally, since the wire harness is drawn out from the high-voltage case in the high-voltage cavity s2 and supplies power to the power-consuming equipment, it can be understood that the wire harness passes through the high-voltage cavity s2 and the wiring passage 16a.
[0268] The communication between the high-voltage cavity s2 and the wiring passage 16a means that a harness routed through the high-voltage cavity s2 can enter the wiring passage 16a. Specifically, the high-voltage cavity s2 is provided with a wiring opening facing the entrance to the wiring passage 16a, in which case there is no obstacle between the wiring opening and the entrance to the wiring passage 16a, and the wire harness routed through the wiring opening can enter the entrance to the wiring passage 16a straight in without bending. Specifically, the high-voltage cavity s2 may have a wiring opening that is spatially communicating with the entrance to the wiring passage 16a without facing it, in which case there is an obstacle between the wiring opening and the entrance to the wiring passage 16a (the obstacle may be formed by the central passage beam 16 or may be another structure), and the wire harness that comes out of the wiring opening can bypass the obstacle and then enter the wiring passage 16a through the entrance to the wiring passage 16a.
[0269] In this case, since the high-voltage cavity s2 and the wiring passage 16a are in communication, it is possible to arrange the wire harness exiting the high-voltage cavity s2 via the wiring passage 16a.
[0270] In some embodiments, referring to Figures 17 and 21, the central passage beam 16 and the high-pressure chamber 15 are arranged adjacent to each other along the first direction F1.
[0271] The central aisle beam 16 generally extends from the front chassis of the vehicle body 200 to the rear chassis of the vehicle body 200, and the high-pressure chamber 15 is located on one side of the central aisle beam 16 in the first direction F1, and the high-pressure chamber 15 can be positioned in front of or behind the central aisle beam 16. Specifically, the high-pressure chamber 15 can be positioned behind the central aisle beam 16, corresponding to the position of the rear chassis of the vehicle body 200, and since the position of the rear chassis of the vehicle body 200 can be used to mount the seats 300 of the passenger compartment of the vehicle 1000, the arrangement of the high-pressure chamber 15 can be realized by concealing the high-pressure chamber 15 in the space below the seats 300, thereby increasing the space utilization rate of the passenger compartment of the vehicle 1000.
[0272] In some embodiments, referring to Figure 11, the top surface h of the housing 10 is formed with a first region ha and a second region hb surrounding the first region ha, and a plurality of mounting parts 13a3 are configured in the second region hb, and the battery 100 is attached to an external device via the mounting parts 13a3.
[0273] The formation of the first region ha and the second region hb can be achieved by another structural division, such that a seal 12 is placed on the top of the housing 10, and the top surface h of the housing 10 is divided into the second region hb located around the seal 12 via the seal 12, and the first region ha located on the inner circumference of the seal 12. When the battery 100 is attached to an external device via the mounting portion 13a3, the first region ha and the second region hb are independent of each other.
[0274] The formation of the first region ha and the second region hb can also be done by automatically partitioning the top surface h such that there is no other structural gap between the first region ha and the second region hb, and the first region ha and the second region hb communicate with each other when the battery 100 is attached to an external device via the mounting portion 13a3.
[0275] 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 may be flat or non-flat surfaces, and their specific configuration is not limited.
[0276] In one specific embodiment, for example, if the external device is the vehicle body 200 of the vehicle 1000, by forming the mounting portion 13a3 in the second region hb, the housing 10 is connected to the vehicle body 200 via a relatively outer region of the top. In this case, the housing 10 receives only the vertical force of the vehicle body 200, reducing the force transmission path and being advantageous in improving the overall rigidity and lateral pressure resistance of the vehicle.
[0277] The top surface h of the housing 10 may include, in addition to the first region ha and the second region hb, other regions that can be located between them, around them, or inside them, and is not particularly limited in this application.
[0278] In some embodiments, referring to Figures 13-14, the distance L2 between the geometric centers of the orthographic projections of each adjacent mounting portion 13a3 in the second region hb is 80 mm to 500 mm.
[0279] Orthographic projection is a projection in which parallel projection lines are projected perpendicularly to the projection plane, that is, a projection in which the mounting portion 13a3 is projected onto the second region hb in a direction perpendicular to the second region hb. When connecting the mounting portion 13a3 to an external device, each mounting portion 13a3 has a mounting force bearing point whose geometric center, orthographically projected onto the second region hb, is the mounting force bearing point. By limiting the distance between two adjacent mounting force bearing points (i.e., distance L2) to 80 to 500 mm, the mounting of the battery 100 to the external device can be made uniform, and the connection strength between the battery 100 and the external device can be improved.
[0280] In a specific embodiment, when the external device is the vehicle body 200 of the vehicle 1000, the mounting portion 13a3 is installed to include a plurality of mounting holes k1, and the housing 10 of the battery 100 is connected to the vehicle body 200 through the plurality of mounting holes k1. The distance L2 between the geometric centers of adjacent mounting holes k1 is within a range defined to ensure that the set distance (i.e., the distance L2) between the mounting holes k1 is controllable. By controlling the set distance between the mounting holes k1, a substantially uniform distribution among the plurality of mounting positions on the housing 10 is ensured, the force received by the vehicle body 200 becomes uniform, and furthermore, the connection rigidity between the vehicle body 200 and the housing 10 at each position is improved.
[0281] In some other embodiments, for example, when individual settings are required to divide the mounting portion 13a3 into a dense mounting area and a sparse mounting area, the distance (i.e., the distance L2) between each pair of mounting holes k1 in the dense mounting area is set as close as possible to the 80 mm side, and the distance (i.e., the distance L2) between each pair of mounting holes k1 in the sparse mounting area is set as close as possible to the 500 mm side, which can be understood to meet the individual needs of local dense mounting and local sparse mounting.
[0282] In some embodiments, referring to FIGS. 13 to 14, the distance L2 between the geometric centers of the orthographic projections of two adjacent mounting portions 13a3 in the second region hb is 80 mm to 300 mm.
[0283] The distance L2 is within the range of 80 mm to 300 mm. That is, while ensuring the uniform connection between the battery 100 and the external device, the connection strength between the battery 100 and the external device can be guaranteed.
[0284] In some embodiments, referring to FIGS. 13 to 14, on the top surface h of the housing 10, a seal area hc for attaching a seal 12 provided between the first region ha and the second region hb, surrounding the first region ha, and contacting the external device is also formed.
[0285] The seal area hc is also part of the top surface h of the housing 10, and is located between the first region ha and the second region hb, forming a non-communicating relationship between the first region ha and the second region hb. The area of the seal area hc is not likely to be excessive, and its main role is to attach the seal 12 to isolate the first region ha and the second region hb from each other. The size, volume, and shape of the seal 12 are set to conform as closely as possible to the seal 12 so as to ensure that the entire seal 12 is assembled in the seal area hc.
[0286] The seal 12 has different states within the sealing area HC. When the seal 12 is in contact with an external device and the housing 10 is fixedly connected to the external device, the seal 12 is in a compressed state and undergoes a certain deformation to ensure sealing performance. When the battery 100 is separated from the external device, the seal 12 returns to its original state.
[0287] In one specific embodiment, taking the example that the external device is the vehicle body 200 of the vehicle 1000, the battery 100 may be attached to the bottom of the vehicle body 200 and sealed to the vehicle body 200 by a seal 12 on the seal area hc. In this case, the first area ha forms the sealed interior of the vehicle body 200, and the second area hb is the exterior of the vehicle body 200. Fluids or solid particles from the exterior of the vehicle body 200 cannot leak into the interior of the vehicle body 200. For example, stones or liquids scattered while the vehicle 1000 is running cannot collide with the interior of the vehicle body 200, thereby achieving sealing performance and structural reliability inside the vehicle body 200.
[0288] If the housing 10 includes a seal 12, the seal 12 can be understood to be attached to the seal area hc and to seal and separate the first region ha and the second region hb. The specific arrangement of the seal 12 has been described in detail above and will be omitted here, but the top surface h of the housing 10 may include other regions in addition to the first region ha, the seal area hc, and the second region hb, which may be located either inside the first region ha or outside the second region hb, and this application does not particularly limit such regions.
[0289] In some embodiments, referring to Figures 13-14, the shortest distance L1 between the geometric center of the orthographic projection of the mounting portion 13a3 in the second region hb and the outer edge of the seal area hc is 30 mm to 200 mm.
[0290] The mounting portion 13a3 is projected onto the second region hb in a direction perpendicular to the second region hb. When the mounting portion 13a3 is connected to an external device, each mounting portion 13a3 has a mounting force-receiving point, and the geometric center of each mounting portion 13a3 projected onto the second region hb is the mounting force-receiving point of each mounting portion 13a3. The shortest distance L1 between the geometric center of the orthographic projection of the mounting portion 13a3 in the second region hb and the outer edge of the seal area hc is the shortest distance between the mounting force-receiving point of each mounting portion 13a3 and the outer edge of the seal area hc.
[0291] The outer edge of the seal area hc is the common boundary line between the seal area hc and the second region hb, and naturally, the seal area hc also has an inner edge which is the common boundary line between the seal area hc and the first region ha. When assembling the seal 12, the side edges of the seal 12 are aligned with the inner and outer side edges of the seal area hc so that the seal 12 completely covers the seal area hc.
[0292] The shortest distance L1 between the geometric center of the orthographic projection of the mounting portion 13a3 in the second region hb and the outer edge of the seal area hc is the length of the perpendicular drawn from the geometric center of each mounting portion 13a3 to the outer edge of the seal area hc, in order to ensure that the distance between the seal 12 and the mounting portion 13a3 is within a specified range.
[0293] In one specific embodiment, for example, when the vehicle body 200 of the vehicle 1000 is used as an external device, the shortest distance (i.e., distance L1) between the mounting force bearing point of the mounting part 13a3 and the outer edge of the seal area hc can be controlled to 30 mm to 200 mm. This prevents the mounting force bearing point of the mounting part 13a3 from being too far from the seal 12, while simultaneously ensuring the sealing effect inside the vehicle body 200 by the seal 12. On the other hand, it reduces the mounting moment when each mounting part 13a3 is attached to the vehicle body 200, effectively shortening the mounting arm and ensuring the connection rigidity between the battery 100 and the vehicle body 200.
[0294] In some embodiments, referring to Figures 13-14, the shortest distance L1 between the geometric center of the orthographic projection of the mounting portion 13a3 in the second region hb and the outer edge of the seal area hc is 50 mm to 100 mm.
[0295] In the range of 50mm to 100mm, the mounting point of the mounting portion 13a3 can be kept from being too far from the seal 12, ensuring the sealing isolation effect of the seal 12 between the first region ha and the second region hb while also ensuring the connection strength between the battery 100 and the external device.
[0296] In some embodiments, the seal area HC is coplane with the second region HB.
[0297] Coplanes, also known as coplanar planes, refer to the state in which a seal area hc and a second region hb share the same plane in three-dimensional space. In this state, both the seal area hc and the second region hb are composed of flat planes, and no angle is formed between them.
[0298] In one specific embodiment, when the external device is the vehicle body 200 of the vehicle 1000, and the housing 10 is assembled to the bottom of the vehicle body 200 via its top, the seal area hc for installing the seal 12 that performs a sealing function and the second area hb where the mounting material is configured to perform a mounting function have the same height in the vertical direction. At this time, the mounting force-receiving points of each mounting part 13a3 are on the same plane and at the same height as the seal area hc, and by having both the mounting force-receiving points and the seal 12 receive only vertical force, the lateral structural force received by the housing 10 and the vehicle body 200 is reduced, and the rigidity of the vehicle 1000 is improved.
[0299] In some embodiments, as shown in Figure 11, the first region ha, the second region hb, and the seal area hc are coplane.
[0300] In this case, the same plane in which the first region ha, the second region hb, and the seal area hc are located comes into contact with the external device. This increases the contact area between the top surface h of the housing 10 and the external device, contributing to improved connection reliability between the housing 10 and the external device, and also improving the appearance by making the top surface structure of the housing 10 relatively flat.
[0301] When the external device is the vehicle body 200 of the vehicle 1000, the inner area, outer area, and seal area hc of the vehicle body 200 on the top surface h forming the housing 10 are all located on the same plane, ensuring that only vertical forces are supported both inside and outside the vehicle body 200 of the housing 10, further reducing the load on the lateral structure of the vehicle 1000.
[0302] In some embodiments, referring to Figure 14, if the mounting portion 13a3 includes at least one mounting hole k1, all mounting holes k1 penetrate the second region hb.
[0303] Reference can be made to the above description for the mounting hole k1, which will be omitted here. When the mounting hole k1 is provided through the second region hb, when connecting the housing 10 and an external device, the connecting member can be connected from the top of the housing 10 to the top of the housing 10 from the second region hb on the relatively outer periphery, and the connection strength between the housing 10 and the external device can be improved.
[0304] In some embodiments, referring to FIG. 14, there is a reserve distance between the outer edge of the seal area hc close to the second region hb and the circumferential side wall n of the main body 11.
[0305] The description of the circumferential side wall n hole of the main body 11 can refer to the above description, which will be omitted here. However, the outer edge of the seal area hc close to the second region hb is not coplanar with the plane in which the circumferential side wall n of the main body 11 is located in the vertical direction, so that there is also a certain reserve distance between the outer edge of the seal area hc and the outer edge of the top surface h1 of the main body 11.
[0306] When the seal 12 is assembled and the seal 12 is not deformed, both side edges of the seal 12 overlap with the inner and outer side edges of the seal area hc. When the seal 12 is hermetically connected to an external device, the seal 12 protrudes beyond both sides of the seal area hc, one side extends into the first region ha beyond the seal area hc, and the other side extends into the second region hb beyond the seal area hc. <The top surface h1 of the main body 11 is the surface on one side of the main body 11 that is located at its top and spaced apart from the housing cavity s. If the housing 10 includes both the main body 11 and the side beam 13 in the above embodiment, the top surface h of the housing 10 may be defined and formed together with the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. In this case, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can be arranged coplanely, which increases the contact area between the top surface h of the housing 10 and the external device, contributing to improved connection reliability between the housing 10 and the external device, and also improves the appearance by making the top structure of the housing 10 relatively flat. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 may not be coplane.
[0310] In other embodiments, the housing 10 may include structures other than the main body 11 and the side beams 13, in which case the top surface h of the housing 10 is defined and formed together with the top surface h1 of the main body 11, the top surface h2 of the side beams 13, and the top surfaces of the other structures.
[0311] The first region ha and the seal area hc are located on the top surface h1 of the main body 11, and the top surface h1 of the main body 11 may include other regions in addition to the first region ha and the seal area hc, and is understood to be not particularly limited thereto.
[0312] In some embodiments, referring to Figures 11 and 13, at least a portion of the second region hb and the first region ha are located on the top surface h1 of the main body 11.
[0313] The top surface h1 of the main body 11 is divided into a first region ha, a seal area hc that surrounds the outside of the first region ha, and a second region hb that surrounds the outside of the seal area hc. When the seal 12 in the seal area hc is compressed and deformed, one side edge of the seal 12 extends into the second region hb on the top surface h1 of the main body 11.
[0314] The second region hb on the top surface h1 of the main body 11 is a reserve distance between the outer edge of the seal area hc near the second region hb and the circumferential side wall n of the main body 11. It can be understood that this ensures sufficient deformation space for the deformation of the seal portion 12 in order to prevent it from overflowing onto the side beam 13 beyond the top surface h1 of the main body 11 when the seal portion 12 deforms.
[0315] In some embodiments, the mounting portion 13a3 is located in a second region hb defined by the top surface h2 of the side beam 13.
[0316] A description of the mounting hole k1 can be found in the above description, so it will be omitted here. The mounting hole k1 is provided in the second region hb defined by the top surface h2, and also has the beneficial effect of having the mounting portion 13a3 provided at the top of the side beam 13, which will also be omitted here.
[0317] If the housing 10 includes both the main body 11 and the side beam 13 in the above embodiment, the top surface h of the housing 10 may be defined and formed together with the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. A reserve distance is provided between the outer edge of the seal area hc near the second region hb and the axial side wall of the main body 11, ensuring sufficient deformation space for the deformation of the seal 12, and preventing the seal 12 from overflowing beyond the top surface h1 of the main body 11 onto the top surface h2 of the side beam 13 and interfering with the mounting of the mounting portion 13a3 on the side beam 13 during deformation.
[0318] In some embodiments, referring to Figure 14, the mounting portion 13a3 is positioned on a first sub-beam 13a1 and / or a second sub-beam 13a2, and in the first direction F1 and / or second direction F2, the distance L2 between the geometric centers of the orthographic projections of two adjacent mounting portions 13a3 in the second region hb is 80 mm to 500 mm.
[0319] A description of the first sub-beam 13a1 and the second sub-beam 13a2 can be found in the above description, so it will be omitted here. By extending the two first sub-beams 13a1 in the first direction F1 and the two second sub-beams 13a2 in the second direction F2, and providing mounting portions 13a3 on each of the first sub-beams 13a1 and / or second sub-beams 13a2, and extending the mounting portions 13a3 in the first direction F1 and / or second direction F2, the attachment and fixing to the external device is uniformly formed in multiple directions, further improving the connection between the external device and the housing 10.
[0320] Furthermore, by setting the distance between the geometric centers of the orthographic projections of two adjacent mounting portions 13a3 in the second region hb and the distance between the geometric centers of adjacent mounting holes k1 to a certain range in a certain setting direction, the set distance between mounting holes k1 can be controlled in the extending direction of the first sub-beam 13a1 and the extending direction of the second sub-beam 13a2, thereby ensuring that a uniform force acts on the vehicle body 200.
[0321] If the enclosure 10 includes an intermediate passage beam 16, it can be understood that the intermediate passage beam 16 is located in the first region ha such that the intermediate passage beam 16 is located in the intermediate region of the main body 11.
[0322] In one embodiment, the housing 10 includes the main body 11 in which the battery cavity s1 is formed, and the high-pressure chamber 15 installed on the top of the main body 11, located in the first region ha, and forming the high-pressure cavity s2 by itself or together with the main body 11. Since the first region ha forms most of the top area of the main body 11, the space utilization rate of the first region ha can be improved by placing the high-pressure chamber 15 in the first region ha.
[0323] In some embodiments of this application, the housing 10 is formed with a battery cavity s1 for housing a battery unit 20 and a high-pressure cavity s2 for housing a high-pressure case, which are provided independently of each other (not shown). When the battery cavity s1 is provided independently of the high-pressure cavity s2, high-temperature gas leaked due to thermal failure of the battery unit 20 in the battery cavity s1 does not enter the high-pressure case, and furthermore, does not cause thermal damage to the high-pressure control system in the high-pressure case, thereby ensuring the normal control function of the high-pressure control system and improving the safety performance of the battery 100.
[0324] On the other hand, according to some embodiments of this application, with reference to Figures 3 and 4, this application provides a battery 100 comprising a housing 10 described in any of the embodiments above and a battery unit 20 housed in a housing cavity s. Since this battery 100 includes the housing 10 described above, it possesses all the beneficial effects of the housing 10 described above, which are omitted here.
[0325] In some embodiments, the battery 100 further includes a high-voltage case (not shown), and the housing 10 has a battery cavity s1 and a high-voltage cavity s2 that are provided independently of each other, with the battery cavity s1 housing a single battery 20 and the high-voltage cavity s2 housing the high-voltage case.
[0326] The high-voltage case is a critical safety barrier for the battery 100 units, housing a high-voltage control system and primarily used for the following purposes: turning the high-voltage circuit on or off according to the vehicle's overall electronic control requirements; providing current and leakage detection terminals; enabling controllable tape carrier disconnection when the external current of the battery 100 units becomes excessive; and disconnecting the high-voltage circuit when the external lines of the battery 100 units are short-circuited, preventing the battery 100 units from igniting. It also allows for easy disconnection of the high-voltage circuit during battery 100 unit repairs.
[0327] In this case, the current from all the individual batteries 20 is connected and aggregated by a high-voltage case, and by supplying safe electrical energy to the outside, a battery 100 that can supply safe external power is realized. For the specific configuration of the high-voltage case, you can refer to the general settings in the art, and this application does not concern specific improvements to the high-voltage case.
[0328] In some embodiments, with reference to Figures 10 and 20, the housing 10 includes a body 11 that surrounds and forms a housing cavity s, the body 11 includes a carrier 11a located at the top of the housing 10 and defining the housing cavity s, and the battery unit 20 is placed on the carrier 11a.
[0329] The descriptions of the main body 11, the top surface of the housing 10, and the carrier 11a can be found in the above description and will be omitted here. In this case, the carrier 11a is a component capable of supporting the weight of the battery unit 20, and may be a carrier plate, carrier block, carrier sheet, carrier frame, etc., and is not specifically limited.
[0330] Specifically, the battery unit 20 is positioned below the carrier 11a, and by jointly bearing the load on the top of the battery housing 10 with the carrier 11a, the rigidity of the top of the battery housing 10 can be increased.
[0331] In some embodiments, as shown in Figures 10 and 20, a single battery unit 20 is suspended from a carrier 11a.
[0332] The fact that the battery unit 20 is suspended from the carrier 11a means that the battery unit 20 is installed vertically below the carrier 11a, and the weight of the battery unit 20 is borne by the carrier 11a. Methods for suspending the battery unit 20 from the carrier 11a include directly bonding the battery unit 20 to the underside of the carrier 11a, connecting the battery unit 20 to the carrier 11a via fasteners so that it is positioned below the carrier 11a, or suspending the battery unit 20 from the carrier 11a via hooks or the like so that it is positioned below the carrier 11a.
[0333] In this configuration, the battery unit 20 is suspended below the carrier 11a, and the bottom cover 11c is located at the bottom of the housing 10. When repairing the inside of the battery 100, the battery unit 20 can be exposed by removing the bottom cover 11c without removing the carrier 11a, making maintenance of the battery 100 more convenient. On the other hand, when repairing the battery 100, the battery unit 20 can be attached to and detached from the carrier 11a from below. In particular, if the carrier 11a is subjected to force as at least part of the chassis of the vehicle 1000, the battery unit 20 can be attached to and detached from below the carrier 11a without removing the carrier 11a, making repair of the battery 100 easier.
[0334] In some embodiments, the battery unit 20 is bonded to the carrier 11a.
[0335] Specifically, the battery unit 20 and the carrier 11a can be bonded together with an adhesive such as epoxy resin adhesive or acrylic ester adhesive, and are not particularly limited. In this case, since the battery unit 20 and the carrier 11a are bonded together, not only is connection made easier, but the structure of the battery 100 can also be simplified.
[0336] Figure 22 is a schematic diagram showing the structure of a single battery unit 20 in some embodiments of this application.
[0337] In some embodiments, referring to Figure 22, the outer surface of the battery unit 20 facing the carrier 11a is the first outer surface m1, and the battery unit 20 includes electrode terminals 21a located on the outer surfaces of the battery unit 20 other than the first outer surface m1.
[0338] As described above, the electrode terminals 21a are used for electrical connection with the electrode assembly 23 inside the battery unit 20 in order to output or input electrical energy from the battery unit 20. At least a portion of the electrode terminals 21a protrudes from the battery unit 20 and is electrically connected to the outside. Series and parallel connections between each electrode terminal 21a realize series and parallel connections between the battery units 20. The electrode terminals 21a are conductive and enable electrical transmission, and may be made of aluminum electrodes, copper electrodes, etc.
[0339] The electrode terminals 21a are located on the outer surface of the battery unit 20 other than the first outer surface m1. The first outer surface m1 is a normal smooth surface facing the carrier 11a, and is free of irregularities such as the electrode terminals 21a and liquid injection holes. The first outer surface m1 is the outer surface on which the battery unit 20 faces upward when the battery unit 20 is suspended from the carrier 11a. Specifically, in one embodiment, the battery unit 20 includes the housing 22 and end cap 21, and the housing 22 and end cap 21 form the internal environment in which the battery unit 20 houses the electrode assembly 23. The end cap 21 is located at one end of the housing 22, and the electrode terminals 21a are located on the end cap 21, in which case either outer surface of the housing 22 can be the first outer surface m1 of the battery unit 20.
[0340] The electrode terminal 21a includes a positive electrode terminal that is electrically connected to the positive electrode sheet in the electrode assembly 23, and a negative electrode terminal that is electrically connected to the negative electrode sheet in the electrode assembly 23. The positive electrode terminal and the negative electrode terminal may be located on the same outer surface of the battery unit 20 (like a rectangular battery unit), or they may be located on two different outer surfaces of the battery unit 20 (like a cylindrical battery unit). If the positive electrode terminal and the negative electrode terminal are located on two different outer surfaces of the battery unit 20, the first outer surface m1 is a surface different from the two outer surfaces of the battery unit 20.
[0341] The battery 100 typically includes, in addition to the individual battery units 20, components such as a sampling wire harness for electrically connecting each battery unit 20, a high-voltage wire harness, and a protective structure for protecting the battery units 20. However, by arranging the electrode terminals 21a on surfaces other than the first outer surface m1 of the battery unit 20, when using components such as the sampling wire harness, high-voltage wire harness, and protective structure for the electrode terminals 21a, the components can be arranged through the space between the battery unit 20 and other structures of the main body 11 other than the carrier 11a (for example, the space between the battery unit 20 and the bottom cover 11c, and / or the space between the battery unit 20 and the inner surface of the main body 11) without being constrained by the carrier 11a, thereby making the arrangement of each component easier. On the other hand, since the first outer surface m1 is a smooth surface, the first outer surface m1 and the carrier 11a can be brought into close contact, enabling close mounting of the battery unit 20 and the carrier 11a. This eliminates the need to secure a spare space between the battery unit 20 and the carrier 11a, contributing to an improvement in the space utilization rate of the battery 100.
[0342] In some embodiments, referring to Figure 22, the battery unit 20 has a second outer surface m2 that is positioned away from the first outer surface m1, and the electrode terminals 21a are located on the second outer surface.
[0343] The second outer surface m2 is the outer surface on which the battery unit 20 is installed facing away from the first outer surface m1, and when the battery unit 20 is suspended from the carrier 11a, the second outer surface m2 faces the bottom cover 11c.
[0344] Furthermore, a gap can be left between the battery unit 20 and the bottom cover 11c, preventing external forces acting on the bottom cover 11c from being transmitted to the battery unit 20 and damaging it. In particular, when the battery 100 is mounted on the bottom of the vehicle 1000 and the bottom cover 11c is located at the very bottom of the battery 100, it is easy for stones or other objects from the ground to fly onto the bottom of the battery 100 and hit the bottom cover 11c while the vehicle 1000 is in motion. In this case, the buffer space can block the transmission of external forces to the battery unit 20 and prevent them from affecting the battery unit 20.
[0345] When the battery unit 20 is positioned at a distance from the bottom cover 11c, a buffer space is formed between the second outer surface m2 and the bottom cover 11c where the portion of the electrode terminals 21a that protrudes from the battery unit 20 is located, and wire harnesses and connecting pieces connected to the electrode terminals 21a can be placed within this buffer space. On the other hand, as described above, the buffer space has the capacity to prevent external forces hitting the bottom cover 11c from acting on the battery unit 20 and damaging it. This means that the buffer space not only blocks the effects of external forces but also allows for the layout of wire harnesses and the like, killing two birds with one stone. Furthermore, the space utilization rate of the buffer space and the battery 100 is also improved.
[0346] In another embodiment, the present application also provides a power consumption device, which includes a battery 100 provided in any of the above embodiments, and which is used to supply electrical energy to the power consumption device. A description of the power consumption device can be found in the above description and is therefore omitted here.
[0347] Since the power consumption device includes the battery 100 described above, it possesses all the beneficial effects of the embodiment described above, and these are omitted here.
[0348] Figure 1 is a schematic diagram showing how a battery 100 is applied to a vehicle body 200 in some embodiments of this application.
[0349] In some embodiments, the power consumption device includes a vehicle 1000, with a battery 100 installed at the bottom of the vehicle body 200. A description of the vehicle 1000 can be found in the above description, so it will be omitted here.
[0350] The vehicle body 200 of the vehicle 1000 is the part used by the vehicle 1000 to carry people and luggage, and includes the driver's cab, passenger compartment, engine room, luggage compartment, etc. The vehicle body 200 generally includes the outer shell and doors, windows, trim, seats 300, air conditioning equipment, etc., which are arranged on the outer shell. The outer shell generally refers to a structure that combines the main load-bearing elements of the vehicle 1000, such as rails, cross members, chassis, and pillars, and the sheet metal parts connected to them. In the embodiment of this application, when it is said that the battery 100 is installed at the bottom of the vehicle body 200, it mainly means that the battery 100 is installed at the bottom of the outer shell.
[0351] In this case, by installing the battery 100 at the bottom of the vehicle body 200, it does not occupy space inside the vehicle body 200, thus contributing to a reduction in the volume and weight of the vehicle body 200.
[0352] 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 positioned to form at least a portion of the chassis of the vehicle body 200.
[0353] The chassis, which is part of the vehicle body 200, is a combination of four parts: the drive system, the running system, the steering system, and the braking system. It is used to support and mount the engine and its various components and assemblies of the vehicle 1000, forming the overall shape of the vehicle 1000, receiving power from the engine, and ensuring normal operation.
[0354] The top of the bottom housing 10, where the chassis is located on the vehicle body 200, directly becomes at least part of the chassis. That is, the top of the housing 10 is used to form at least part of the chassis of the vehicle body 200. By integrating the top of the housing 10 with the chassis of the vehicle body 200 in this way, the space occupied by the gap between the conventional chassis and the battery 100 is divided into a space that expands the battery 100 within the battery 100, thereby improving the energy of the battery 100 and improving the driving range of the vehicle 1000.
[0355] In some embodiments of this application, the power consumption device includes a vehicle 1000, and the battery 100 is installed at the bottom of the vehicle body 200 of the vehicle 1000. The battery 100 includes a housing 10 having a carrier 11a located at the top, and a battery unit 20 located inside the housing 10 and suspended from the carrier 11a, the electrode terminals 21a of the battery unit 20 located on the outer surface of the battery unit 20 spaced apart from the carrier 11a, and the carrier 11a forms at least a part of the chassis of the vehicle 1000. In this case, since the battery 100 is suspended only from the carrier 11a, the strength of the carrier 11a can be improved, and the strength of the top of the battery unit 20 can be improved, and a certain load-bearing requirement can be achieved when the carrier 11a is used as the chassis. On the other hand, the electrode terminals 21a of the battery unit 20 are spaced apart from the carrier 11a, allowing the battery unit 20 to be directly attached to the carrier 11a. This eliminates the need for an air gap between the battery unit 20 and the carrier 11a, and the resulting space can be used to increase the mounting space for the battery unit 20, thereby improving the energy of the battery 100 and ultimately improving the driving range of the vehicle 1000.
[0356] Each component of the embodiments described above can be combined in any way, and for the sake of brevity, not all possible combinations of each component in the embodiments described above are described. However, as long as these combinations of components are inconsistent, they should all be considered to fall within the scope described herein.
[0357] The above embodiments represent only a few examples of the present application, and although the descriptions are specific and detailed, they should not be understood as limiting the scope of the patent of this application. Those skilled in the art should note that some modifications and improvements can be made, provided they do not deviate from the concept of this application, and all of these fall within the scope of protection of this application. Therefore, the scope of protection of this application should be in accordance with the claims.
