Description

[Technical field]

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

[0002] As new energy technology becomes more and more mature, new energy vehicles are gradually entering the public's field of vision. The main core technology of new energy vehicles is the battery, and the safety and stability of the battery directly determine the performance of the entire vehicle.

[0003] A vehicle typically includes a vehicle body and a battery mounted on the vehicle body, and in the related art, the battery is mounted on the vehicle body, in which case most of the battery is exposed to the bottom of the vehicle body, and the wire harness connecting the battery to the vehicle's electrical components (such as air conditioner, lights, power drive system, etc.) is also exposed to the outside, making it vulnerable to damage and adversely affecting the safety of the battery. Summary of the Invention [Problem to be solved by the invention]

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

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

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

[0007] In some embodiments, the wiring portion is disposed on a side wall of the housing that is adjacent to the top surface of the housing itself. In this case, the wiring portion is disposed on the side wall of the housing, and the side operation space of the housing is increased, so that the wiring portion can be more easily disposed on the wire harness.

[0008] In some embodiments, the wiring parts are disposed on two side walls adjacent to the top surface of the housing and facing away from each other. In this case, the wiring parts may be disposed symmetrically opposite each other in the first direction, or may be disposed opposite each other in the second direction, and the wire harness may be passed through both sides of the housing in the first direction at the same time, or may be passed through both sides of the housing in the second direction at the same time, thereby realizing a symmetrical arrangement of the wire harness, realizing a more beautiful arrangement of the wires, and contributing to the balance of the vehicle weight.

[0009] In some embodiments, the wire passage portion includes a wire passage groove formed in a concave shape on the outer wall of the housing toward the receiving cavity. In this case, the wire passage groove has an opening, and the provision of the opening makes it easier to pass the wire harness through. In addition, since the concavely formed wire passage groove is configured as the wire passage portion, there is no need to add another structure to form a wire passage space, and the structure of the housing is simpler and less expensive.

[0010] In some embodiments, the housing includes a body forming a receiving cavity and a side beam, the top of the body forms at least a part of the top of the housing, the battery is attached to an external device via the top of the housing, and the body has a circumferential side wall disposed around an outer edge of the top of the body. The side beam is disposed on the circumferential side wall. In this case, the side beam is provided on the side peripheral wall of the body, and the lateral structural strength of the body can be strengthened by the side beam, and the lateral pressure resistance of the housing can be improved, and the lateral pressure resistance of the vehicle can be improved when the battery is applied to the vehicle, thereby improving the safety of the vehicle.

[0011] In some embodiments, the side beam is configured to form a wire passage, in which the wire passage is formed in the side beam, i.e., the side beam has a wire passage space, which can reduce the weight of the side beam and realize the wire passage, killing two birds with one stone.

[0012] In some embodiments, the side beam includes an upper arm beam and a lower arm beam that are spaced apart from each other vertically and are both connected to the main body, and the upper arm beam and the lower arm beam are configured to form a wire-passing section having a wire-passing space. In this case, in a structure in which the main body is reinforced with the upper arm beam and the lower arm beam, the upper arm beam and the lower arm beam are separately arranged, so that the impact force received by the housing can be dispersed, and the external force received by each part of the housing can be relatively uniform. At the same time, by arranging the upper arm beam and the lower arm beam at intervals vertically, the sub-beam can withstand the pressure in the front-rear or left-right direction of the vehicle, and can be more suited to the actual usage situation of the vehicle, and can form a wire-passing space in the shape of a wire-passing groove, making wiring easy.

[0013] In some embodiments, the top of the side beam is configured with a mounting portion, and the battery is attached to the external device through the mounting portion. The mounting portion is a dedicated structure provided on the top of the housing for connection with a connecting member (e.g., a bolt, a rivet, etc.) of the external device, one end of the connecting member can be connected to the mounting portion, and the other end of the connecting member is connected to the external device to fixedly connect the battery to the external device. In this case, the mounting portion is provided on the side beam, which makes it easier to attach the housing to the external device by making the operation space larger.

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

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

[0016] In some embodiments, the body includes a carrier and a frame that encloses a cavity with at least a top end of the carrier penetrating therethrough, the carrier covers the top end of the cavity, and the carrier and the frame enclose and form at least a partial receiving cavity. The side beam is installed on the circumferential side wall defined by the frame. At this time, the cavity formed by the frame mainly constitutes the receiving cavity of the housing, and the receiving cavity has a certain height to receive a plurality of cell units, so that the frame also has a certain height, and therefore the circumferential side wall area of ​​the frame is large. At this time, the side beam is installed on the circumferential side wall defined by the frame, and the mounting manner, mounting area and arrangement manner of the side beam are more flexible.

[0017] In some embodiments, the side beam is fixedly connected to the frame or is integrally molded. When the side beam and the frame are integrally molded, the assembly process of the housing can be reduced and the manufacturing process of the housing can be expedited. When the side beam and the frame are fixedly connected, the molding process of the side beam and the frame can be simplified and the processing cost of the housing can be reduced.

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

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

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

[0021] In some embodiments, the outer surface of the battery unit facing the carrier is a first outer surface, and the battery unit includes an electrode terminal disposed on the outer surface of the battery unit other than the first outer surface. In this case, the electrode terminal is located on the outer surface of the battery unit other than the first outer surface, and various members (e.g., a sampling harness, a high voltage harness, a guard structure, etc.) connecting each electrode terminal can be disposed 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 member more convenient. In addition, in this case, by connecting the first outer surface on which the electrode terminal is not provided to the carrier, it is possible to realize close contact between the battery unit and the carrier, it is possible to save the space between the battery unit and the carrier, and it is possible to improve the space utilization rate of the battery.

[0022] In some embodiments, the battery unit has a second outer surface arranged back to back with respect to the first outer surface, and the electrode terminal is arranged on the second outer surface. In this case, a buffer space is formed between the second outer surface and the bottom cover, in which the electrode terminal is located at a portion protruding from the battery unit, and a wire harness or a connection piece connected to the electrode terminal can be arranged in the buffer space. In addition, the buffer space can prevent the battery unit from being damaged by an external force that strikes the bottom cover. This kills two birds with one stone, as the buffer space not only blocks the influence of the external force, but also enables the layout of the wire harness, etc.

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

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

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

As the application fields of batteries expand, the market demand is also continuing to increase.

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

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

[0039] Based on the above-mentioned idea, the present inventors conducted extensive research to improve the safety of the battery, and came up with a housing having a housing cavity for housing a single battery and a top surface facing away from the housing cavity, the top surface of the housing being arranged to contact an external device to which the battery is attached. Among them, a wiring part is formed on the outer wall of the housing, located below the top surface of the housing and having a wiring space formed therein for passing the wire harness. By forming the wiring part on the outer wall of the housing and passing the wire harness through the wiring space formed by the wiring part, it is possible to effectively protect the wire harness by preventing unnecessary safety risks caused by the wire harness being pressed and deformed when the vehicle is pressed from the outside.

[0040] The battery disclosed in the embodiments of the present application can be used in, but is not limited to, a power consuming device such as a vehicle, a ship, or an aircraft. A power supply system including the battery disclosed in the present application and configuring the power consuming device can be used.

[0046] The end cap 21 is a member that covers the opening of the housing 22 to isolate the internal environment of the battery unit 20 from the external environment. Although not limited, the shape of the end cap 21 can be adapted to the shape of the housing 22 to be fitted into the housing 22. Optionally, the end cap 21 may be formed of a material (e.g., aluminum alloy) having a certain hardness and strength, so that the end cap 21 is less likely to deform when pressed against the battery unit 20, and the structural strength of the battery unit 20 can be increased, thereby improving safety. The end cap 21 may be provided with a functional component such as an electrode terminal 21a.

Fig. 6 is a schematic view showing a part of the structure of the battery 100 in some embodiments of the present application. Fig. 7 is an enlarged view of the part B in the structure shown in Fig. 6, Fig. 8 is a plan view of the structure shown in Fig. 6, Fig. 9 is a side view of the structure shown in Fig. 6, and Fig. 10 is a cross-sectional view of the part CC in the structure shown in Fig. 9.

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

[0055] The top surface of the housing 10 includes a top surface h of the housing 10 and other structures provided on the top surface h of the housing 10. The top surface h of the housing 10 is the vertical upper 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, a connection material (e.g., bolts, rivets, etc.) that connects the top surface h of the housing 10 to an external device, and a seal structure (e.g., seal strips, etc.) that seals the housing 10 to an external device.

[0056] The external device is a device for mounting the housing 10. The external device may be a local structure for mounting the housing 10 among the above-mentioned power consuming devices, or may be a remaining structure of the power consuming device that forms the power consuming device together with the battery 100.

Specifically, the main body 11 may be formed by combining a first child part (not shown) and a second child part (not shown). In one example, the first child part surrounds and forms the receiving cavity s with one end open, and the second child part covers the opening of the receiving cavity s. In another example, the first child part surrounds and forms a first space with one end open, and the second child part surrounds and forms a second space with one end open, so that the openings of both the first child part and the second child part are covered by each other to form the receiving cavity s consisting of the first space and the second space. The first child part and the second child part can be welded, engaged, fastened, etc. The first child part and the second child part may be made of plastic, metal, and other materials.

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

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

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

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

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

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

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

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

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

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

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

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

[0073] When the battery 100 is attached to an external device via the mounting portion 13a3, the top surface h of the housing 10 comes into contact with and connects to the external device, thereby improving the connection strength while ensuring a compact connection structure between the housing 10 and the external device.

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

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

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

[0077] The connecting piece may be a rivet, and a fixing hole 11c3 is provided at the position of the external device corresponding to the mounting hole k1, and the rivet is passed through the fixing hole 11c3 and the mounting hole k1, and then the two are fixed with a nut. It is also possible to connect to the housing 10 by using a screw as the connecting material, a screw hole as the mounting hole k1, and passing the screw through the mounting hole k1 for screw connection.

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

[0079] As can be appreciated, the mounting portion 13a3 may have other mounting features 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 having at least an upper end thereof extending therethrough and surrounding a cavity therein, the carrier 11a covering the upper end of the cavity, and the carrier 11a and the frame 11b surrounding and forming at least a partial receiving cavity s.

[0081] The frame 11b is surrounded by itself to form a cavity through which at least the top end is installed, and the top of the cavity is covered by the carrier 11a, that is, the carrier 11a is located at the top of the housing 10 to define the receiving cavity s. The frame 11b and the carrier 11a may be made of the same material such as aluminum alloy, copper alloy, steel, plastic, etc. Of course, the frame 11b, the carrier 11a, and the bottom cover 11c may adopt different materials, and are not specifically limited. In the vertical orthogonal projection, the frame 11b may be rectangular, circular, polygonal, etc., and are not specifically limited. The carrier 11a may be a carrier plate, a carrier sheet, a 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 be formed together with the top surfaces of the carrier 11a and the frame 11b, in which case the carrier 11a is located inside the frame 11b, and the top surfaces of the carrier 11a and the frame 11b may or may not be coplanar.

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

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

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

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

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

[0088] The bottom cover 11c and the frame 11b can be fixed to each other by welding, heat fusion, adhesion, fastening, engagement, etc. Here, fastening connection refers to connection by the fixing piece 11c4 including parts such as bolts, plugs, rivets, pins, screws, etc. Here, engagement refers to fixing by an engagement structure. For example, the bottom cover 11c has an engagement hook, the frame 11b has an engagement port, and when the engagement hook engages with the engagement port, the bottom cover 11c and the frame 11b are engaged and fixed. 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 is used as a base, and the carrier 11a and the bottom cover 11c are connected to both vertical ends of the frame 11b to form a cavity s for housing the battery 100, so the structure of the main body 11 is relatively simple.

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

[0091] The lid portion 11c1 defines the storage cavity s means that the lid portion 11c1, together with the carrier 11a and the frame 11b, surrounds and forms the storage cavity s, and the mounting portion 11c2 is connected to the frame 11b without being involved in the definition of the storage 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 mounting portion 11c2 being surrounded by the edge of the lid portion 11c1 means that the mounting portion 11c2 is connected along the edge of the lid portion 11c1 and the front and rear are connected in a closed manner. The mounting portion 11c2 has a certain width when projected in the vertical direction, so that it has an appropriate contact area with the frame 11b, and can easily 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. When the bottom lid 11c is made of metal (for example, aluminum, iron, stainless steel, etc.), the lid portion 11c1 and the mounting portion 11c2 may be integrally molded by die casting, forging, hot pressing, cold pressing, etc. When the bottom lid 11c is made of plastic (polypropylene, polyethylene, ABS (Acrylonitrile Butadiene Styrene plastic), etc.), the lid portion 11c1 and the mounting portion 11c2 may be integrally molded by injection molding. The lid portion 11c1 and the mounting portion 11c2 may be connected after being molded separately. When 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. When the lid portion 11c1 and the mounting portion 11c2 are made of plastic, the lid portion 11c1 and the mounting portion 11c2 may be bonded. Of course, the cover portion 11c1 and the attachment portion 11c2 may be fixedly joined by other methods such as engagement or riveting.

[0093] The lid portion 11c1 and the mounting portion 11c2 may be located in the same plane. Specifically, selectively, both surfaces of the lid portion 11c1 and the mounting portion 11c2 facing the carrier 11a are 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 one flat bottom lid 11c.

[0094] The lid portion 11c1 and the mounting portion 11c2 do not have to be located in the same plane. Specifically, the lid portion 11c1 may be recessed toward the carrier 11a with respect to the mounting portion 11c2, or the lid portion 11c1 may protrude away from the carrier 11a with respect 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 is not specifically limited.

[0095] At this time, the bottom cover 11c defines the accommodation cavity s via the cover portion 11c1 and realizes connection with the frame 11b via the attachment portion 11c2, so that the structure is clear and attachment is easy.

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

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

[0098] Specifically, the bottom cover 11c further includes a fixing hole 11c3 provided in the mounting portion 11c2, and the fixing device 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 passes through the mounting portion 11c2 in the vertical direction, and specifically, the fixing hole 11c3 may be a smooth through hole (for example, when the fixing device 11c4 is a rivet), a through hole with a thread (for example, when the fixing device 11c4 is a screw), or a through hole of another type (hexagonal hole, square hole, waist hole, etc.). The specific shape of the fixing hole 11c3 is determined by the specific shape and specific setting method of the fixing device 11c4, and will not be described here.

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

[0100] The side beam 13 is a beam structure provided on the peripheral side wall n of the main body 11 to reinforce the strength of the main body 11. As can be understood, the side beam 13 is located outside the main body 11. Specifically, the main body 11 may be integrally connected to the side beam 13 to form an integrated unit, or may be connected to the side beam 13 by an assembly method to form an integrated unit. The integral connection method includes, but is not limited to, welding, integral molding, fusion, etc. The assembly connection method includes, but is not limited to, engagement, fastening connection, etc.

[0101] The side beams 13 may be disposed on the entire circumferential side wall n of the main body 11, or may be disposed on only a part of the circumferential side wall n of the main body 11. Without being limited thereto, by disposing 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 a plurality of side directions of the main body 11. Specifically, the side beams 13 are provided continuously or intermittently around the circumferential side wall n of the main body 11. When the side beams 13 are disposed continuously, they can be annular beams, and when they are disposed intermittently, they can include a plurality of beam portions disposed at intervals around the circumferential side wall n of the main body 11.

[0102] In some practical application scenarios, the housing 10 is used for the battery 100, the battery 100 is applied to the vehicle 1000, 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 for the battery 100 is used as the chassis of the vehicle 1000, the lateral structure of the housing 10 is easily subjected to external impact (for example, stones scattered while the vehicle 1000 is running hit the lateral position of the housing 10, or the housing 10 is hit by another vehicle 1000 at the lateral position, etc.) and is extruded. At this time, a side beam 13 is provided on the side peripheral wall of the main body 11, and the side structural strength of the main body 11 can be strengthened by the side beam 13, and the lateral pressure resistance of the housing 10 can be improved, and at the same time, the lateral pressure resistance of the vehicle 1000 can be improved, and the safety of the vehicle 1000 can be improved.

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

[0104] The cavity formed by the frame 11b mainly constitutes the accommodating cavity s of the housing 10, and the accommodating cavity s has a certain height so as to accommodate a plurality of single batteries 20, so the frame 11b also has a certain height and the area of ​​the circumferential side wall n of the frame 11b is relatively large. At this time, the side beams 13 are installed on the circumferential side wall n defined by the frame 11b, and the mounting method, mounting area and arrangement method of the side beams 13 are more flexible.

[0105] Furthermore, in the embodiment, the side beam 13 is fixedly connected to the frame 11b or is molded integrally therewith. The side beam 13 and the frame 11b may be fixedly joined by a method such as welding, fusion, riveting, or screwing, or may be integrally formed by integral processing (for example, pressing, die casting, etc.).

[0106] By integrally molding the side beams 13 and the frame 11b, it is possible to reduce the assembly process of the housing 10 and to speed up the manufacturing process of the housing 10. By fixedly connecting the side beams 13 and the frame 11b, the molding process of the side beams 13 and the frame 11b becomes easier and the processing cost of the housing 10 can be reduced.

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

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

[0109] The structure of the sub-beam 13a may be of multiple types, and the structure of each sub-beam 13a may be the same or different. For example, the sub-beam 13a is a solid beam extending in one longitudinal direction, and for example, the sub-beam 13a is a hollow beam extending in one longitudinal direction. The cross-sectional shape of each sub-beam 13a may be a structural shape such as an H-shape or a U-shape.

[0110] In this case, since the side beam 13 is formed by combining a plurality of sub-beams 13a, the degree of freedom in arranging the side beams 13 is increased, and during installation, each sub-beam 13a only needs to be installed one by one, making positioning during installation easier and less labor-intensive than with an integral side beam 13.

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

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

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

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

[0115] In some embodiments, at least one of the upper arm beam 131 and the lower arm beam 132 is a hollow beam. A hollow beam means that the inside of the beam is a hollow structure, 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 have a hollow beam structure, not only can the weight of the upper arm beam 131 and the lower arm beam 132 be reduced, but also, when the battery 100 formed with the housing 10 is applied to a power consumption device such as a vehicle 1000, the problem of an increase in the energy consumption of the battery 100 itself due to its large weight can be reduced. In addition, the hollow beam structure can consume a lateral pressure force by its internal space, and can reduce the degree of damage to the battery 100 when it is subjected to a lateral pressure force.

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

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

[0118] The structure of the sub-beams 13a on each first wall segment n1 can be made the same, and the pressing resistance can be ensured to be consistent on both the left and right sides of the vehicle 1000. Furthermore, the sub-beams 13a in the first wall segment n1 include the upper arm beam 131 and the lower arm beam 132 described in the above-mentioned embodiment, and since the pressing resistance of the sub-beams 13a is high at this time, the characteristic that the structure on both the left and right sides of the vehicle 1000 is weak can be compensated for, and the pressing resistance on both the left and right sides of the vehicle 1000 can be strengthened, and the safety of the vehicle 1000 can be improved.

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

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

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

[0122] The structure of the sub-beams 13a on each second wall segment n2 can be made the same, and the pressing resistance force on both the front and rear sides of the vehicle 1000 can be ensured to be consistent. Furthermore, the sub-beams 13a of the first wall segment n1 can 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 body 11, and in this case, the pressing resistance force of the sub-beams 13a is weak. This is because a pressing resistance structure such as a bumper is generally provided in the front and rear directions of the vehicle 1000, and when the vehicle 1000 is pressed in the front and rear directions, the pressing resistance effect is mainly realized by the front and rear bumpers provided. In this case, the sub-beams 13a of the second wall segment n2 do not require a strong pressing resistance force, so a relatively simple sub-beam 13a structure can be adopted, and the cost of the battery 100 and the cost of the vehicle 1000 can be reduced.

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

[0124] In some embodiments, with continued reference to FIG. 6, the side beam 13 includes at least two first sub-beams 13a1 and at least two second sub-beams 13a2, both of which are 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] At this time, the sub-beam 13a provided in the first wall segment n1 is the first sub-beam 13a1, and the sub-beam 13a provided in the second wall segment n2 is the second sub-beam 13a2. The two first sub-beams 13a1 can reinforce the pressing resistance force of the housing 10 in the left-right direction of the vehicle 1000, and the two second sub-beams 13a2 can reinforce the pressing resistance force of the housing 10 in the front-rear direction of the vehicle 1000. Therefore, the lateral pressing resistance force of the vehicle 1000 can be improved overall, and the safety of the vehicle 1000 can be improved.

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

[0127] The above description can be used as a reference for the introduction of the mounting portion 13a3, so it will be omitted here. At this time, by providing the mounting portion 13a3 at the top of the side beam 13, the side beam 13 can be added based on the structure of the existing housing 10 to obtain the housing 10 of the embodiment of the present application. This can significantly reduce the cost of modification. 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, there is no need to consider the effect of the mounting portion 13a3 on the sealing property 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, the mounting portion 13a3 is provided on the side beam 13, and the operation space when attaching the housing 10 to an external device becomes larger, making it more convenient.

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

[0129] The above description can be used as a reference for the description of the mounting hole k1, so it will be omitted here. The mounting hole k1 is provided at the top of the side beam 13, and has the beneficial effect of providing the mounting portion 13a3 at the top of the side beam 13, so it will be omitted here.

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

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

[0132] When the housing 10 includes both the main body 11 and the side beam 13 in the above embodiment, the top surface h of the housing 10 may be defined and formed together with the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. In this case, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can be arranged coplanarly, so that the contact area between the top surface h of the housing 10 and the external device is increased, which can contribute to improving the connection reliability between the housing 10 and the external device, and the top surface structure of the housing 10 can be made relatively flat to improve the 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 coplanar.

[0133] As can be understood, when the side beam 13 includes at least two sub-beams 13a, the top surface of each sub-beam 13a defines a part of the top surface h2 forming the side beam 13, and the sub-beams 13a are provided with the mounting portion 13a3. Among them, some of the sub-beams 13a may be provided with the mounting portion 13a3, or all of the sub-beams 13a may be provided with the mounting portion 13a3. When some of the sub-beams 13a are provided with the mounting portion 13a3, in order to ensure uniformity of the force received by the mounting portion 13a3, all of the symmetrically installed sub-beams 13a are provided with the mounting portion 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, a wire passing portion 13a4 is formed on the outer wall of the housing 10, which is located below the top surface h of the housing 10 and forms a wire passing space for passing the wire harness.

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

[0136] When the housing 10 includes only the main body 11, the side wall of the housing 10 can be the circumferential side wall n of the main body 11. When the housing 10 includes the main body 11 and the side beam 13, the side wall of the housing 10 includes the circumferential side wall n of the main body 11 that is not covered by the side beam 13, and the surface of the side beam 13 facing away from the main body 11.

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

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

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

[0140] In yet another embodiment, with continued reference to FIGS. 6 and 10, the wire-passing portion 13a4 is disposed on a side wall of the housing 10 adjacent to its top surface h.

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

[0142] In this case, since the wire-passing portion 13a4 is disposed on the side wall of the housing 10 and the side operation space of the housing 10 is increased, arrangement in the wire harness becomes easier.

[0143] In some embodiments, the wire portions 13a4 are disposed 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 of the housing 10 adjacent to the top surface h and facing each other include two side walls facing in the first direction F1 and two side walls facing in the second direction F2. In this case, the wire-passing portions 13a4 may be arranged symmetrically opposite each other in the first direction F1 or may be arranged opposite each other in the second direction F2, and the wire harness may be passed through simultaneously from both sides of the housing 10 in the first direction F1 or from both sides of the housing 10 in the second direction F2, thereby realizing a symmetrical arrangement of the wire harness, which can realize a more beautiful arrangement of the wires and also contribute to the balance of the vehicle weight 1000.

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

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

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

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

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

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

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

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

[0153] When the wire-passing portion 13a4 is a wire-passing hole, the side beam 13 can be configured to have a hollow beam penetrating both ends in the extension direction, so that the internal space of the side beam 13 forms the wire-passing hole. Alternatively, the side beam 13 includes the upper arm beam 131, the lower arm beam 132, and the intermediate beam (not shown) in the above-mentioned embodiment, and the wire-passing hole is surrounded by the intermediate beam, the upper arm beam 131, and the lower wall beam.

[0154] At this time, the wire passing portion 13a4 is formed in the side beam 13, that is, the side beam 13 has a space for passing wires, which can reduce the weight of the side beam 13 and realize the passing of wires, thus killing two birds with one stone.

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

[0156] Fig. 11 is a schematic diagram showing a structure of a part of a battery 100 in some other embodiments of the present application, Fig. 12 is an exploded side view of the structure shown in Fig. 11, Fig. 13 is a side view of the structure shown in Fig. 11, and Fig. 14 is an enlarged view of part D in the structure shown in Fig. 12. Fig. 15 is a schematic diagram showing an application scenario of the structure shown in Fig. 11, and Fig. 16 is a side view of the structure shown in Fig. 14.

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

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

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

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

[0161] As can be seen, 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, with the top surface h of the housing 10 in contact with the external device.

[0162] Taking the external device as an example of the body 200 of the vehicle 1000, the battery 100 may be attached to the bottom of the body 200 and sealed and connected to the body 200 by the seal 12 on the sealing area hc, in this case, the internal region of the seal 12 is the internal region of the body 200, and the external region is the external region of the body 200, and fluids or solid particles etc. outside the body 200 cannot leak into the internal region of the body 200, for example, stones or liquids scattered during the running of the vehicle 1000 cannot collide with the internal region of the body 200, thereby realizing the sealing property and structural reliability of the internal region of the body 200.

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

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

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

[0166] In this way, by integrating and installing the partial structures of the battery 100 and the external device, the partial structure of the housing 10 of the battery 100 can be made a partial structure of the external device, thereby making it possible to avoid installing the battery 100 and the external device separately.

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

[0168] In one specific embodiment, as shown in Figures 14 and 15, for example, the external device is the body 200 of the vehicle 1000, and the mounting position 141b is used to mount a seat 300. By configuring the mounting position 141b at the top of the housing 10 of the battery 100, the internal structure of the body 200 is formed at the mounting position 141b, and by integrating the battery 100 and the body 200, it is possible to avoid installing the battery 100 and the body 200 separately, simplify the structure of the vehicle 1000, and achieve a smaller and more compact design.

[0169] As can be understood, the fixed connection of the housing 10, the body 200 and the seat 300 ensures that all structures are connected to the top and bottom of the housing 10 along the vertical direction, which can reduce the installation space and installation load in other directions of the housing 10, reduce the load on the lateral structure and bottom structure of the housing 10 of the battery 100, and improve the structural stability of the vehicle 1000.

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

[0171] The mounting hole is a through hole that passes vertically through the mounting position 141b, and a fastener must be installed when mounting the mounting sheet 300 or the like to the mounting position 141b, but the mounting hole may be a smooth through hole (for example, in the case of a rivet), a through hole with a thread (for example, in the case of a screw), or another type of through hole (hexagonal hole, square hole, waist hole, etc.). The specific shape of the fixing hole 11c3 is determined by the specific shape and specific setting method of the fastener, and will not be described here.

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

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

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

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

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

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

[0178] The installation form and extension direction of the load-bearing structure are set according to the size, weight, and specific structure of the mounting material that needs to be attached to the mounting position 141b, and without being specifically limited, 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 casing 10 of the battery 100.

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

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

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

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

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

[0184] In other embodiments, the main body 11 is connected to a portion other than the mounting beam 141, and the connection method may be integral molding or fixed connection. There is no specific limitation.

[0185] In some embodiments, referring to Figures 7 and 11, the mounting beam 141 includes at least one protrusion 141a, each of which is provided to protrude from the top of the main body 11 in a direction away from the accommodating cavity s, each of which forms a weight reduction passage 141a1 together with the main body 11, and the mounting position 141b is configured on one side where the protrusion 141a faces away from the main body 11.

[0186] The protrusions 141a are load-bearing structures included in the mounting beam 141 described above, and are provided so as to protrude in a direction away from the housing cavity s, facing the plane on which the top surface h of the housing 10 is located, and the protrusions 141a themselves have a certain height and are provided so as to protrude relative to the top surface h of the housing 10. The mounting position 141b is formed such that all the protrusions 141a are formed on one side away from the main body 11, and at this time, 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 that the force received by the top surface of the housing 10 is distributed by the protrusions 141a, and the load-bearing capacity of the top of the housing 10 is increased.

[0187] Each of the protrusions 141a can have a structure that is open on multiple sides with one end as the center, and the top surface h1 of the main body 11 covers the open opening of each of the protrusions 141a, forming a weight reduction passage 141a1 together with the top surface h1. The weight reduction passage 141a1 can be formed by making the inside of the protrusion 141a hollow or by digging a hole or a groove, and the weight of the housing 10 can be reduced.

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

[0189] In some embodiments, referring to FIGS. 6 to 7, all the protrusions 141a extend in the same direction and are spaced apart from one another.

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

[0191] The fact that all the protrusions 141a are arranged at intervals from one another means that, in a direction intersecting the extension direction of the protrusions 141a, a set interval is arranged between each pair of adjacent protrusions 141a. Under the effect of this set interval, a buffer space is formed between each pair of adjacent protrusions 141a, and it is possible to prevent an external force acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. In addition, the protrusions 141a arranged at multiple intervals can form a sufficient support area and fixing position, and can support the mounting material over a large area, making it possible to apply to the mounting of mounting materials with different volumes and sizes.

[0192] Since all the protrusions 141a are arranged parallel to one another 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 extension direction of the mounting beam 141.

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

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

[0195] By installing all of the protrusions 141a so that they protrude in the same direction and making the protruding heights of all of the protrusions 141a the same, one side of all of the protrusions 141a away from the mounting cavities forms a flat plane in a certain direction so as to form a flat plane on a horizontal plane, and the mounting material can be placed on the flat plane and mounted more smoothly and easily, and a strong bond 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, which together define and form the mounting position 141b for mounting the mounting material, thereby allowing the mounting material to be smoothly placed on the mounting beam 141.

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

[0198] The side reinforcement beam 14 is a beam structure installed on the top of the main body 11 to reinforce the strength of the main body 11. As can be understood, the side reinforcement beam 14 is located outside the main body 11. Specifically, the main body 11 may be integrally connected to the side reinforcement beam 14 to form an integrated unit, or may be assembled and connected to form an integrated unit. The integral connection includes, but is not limited to, welding, integral molding, fusion, etc. The assembly connection includes, but is not limited to, engagement, screw connection, etc.

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

[0200] The side reinforcement beam 14 may extend in two directions on the same line from the center of the top of the main body 11 toward the outer edges on both opposing sides of the top of the main body 11, or may extend in two intersecting directions from the middle of the top of the main body 11 toward the outer edges on both opposing sides of the top of the main body 11. When the side reinforcement beam 14 extends from the middle of the top of the main body 11 toward the outer edges on both opposing sides in two directions on the same line, the side reinforcement beam 14 is realized by a single straight beam, making the structure simpler.

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

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

[0203] In this case, by providing a side impact reinforcement beam 14 at the top of the main body 11 of the housing 10, the side impact prevention capability of the housing 10 can be improved, and further, the side impact prevention capability of the vehicle 1000 equipped with the battery 100 made of this housing 10 can be improved, thereby contributing to ensuring the safety of the battery 100 and the vehicle 1000.

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

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

[0206] At this time, the top of frame 11b also forms part of the top of main body 11, and side collision reinforcement beam 14 can extend so as to connect with the top of frame 11b. In addition to directly connecting frame 11b and carrier 11a, the connection can be strengthened by side collision reinforcement beam 14, thereby improving the connection reliability between frame 11b and carrier 11a.

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

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

[0209] Since 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 extension direction, it is possible to strengthen the side impact prevention capability of the housing 10 in the extension direction. As can be understood, each side impact reinforcing beam 14 is disposed at intervals in a direction intersecting this "same direction", and by arranging in this manner, it is possible to reinforce the strength at multiple positions of the housing 10 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 impact reinforcement beams 14 is configured as an attachment beam 141 having an attachment location 141b configured on one side spaced away from the body 11.

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

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

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

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

[0215] Each of the protrusions 141a can have a structure that is open on multiple sides with one end as the center, and the top surface h1 of the main body 11 covers the open opening of each of the protrusions 141a, forming a weight reduction passage 141a1 together with the top surface h1. The weight reduction passage 141a1 can be formed by making the inside of the protrusion 141a hollow or by digging a hole or a groove, and the weight of the housing 10 can be reduced.

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

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

[0218] The fact that all the protrusions 141a are arranged at intervals from one another means that, in a direction intersecting the extension direction of the protrusions 141a, a set interval is arranged between each pair of adjacent protrusions 141a. Under the effect of this set interval, a buffer space is formed between each pair of adjacent protrusions 141a, and it is possible to prevent an external force acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. In addition, the protrusions 141a arranged at multiple intervals can form a sufficient support area and fixing position, and can support the mounting material over a large area, making it possible to apply to the mounting of mounting materials with different volumes and sizes.

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

[0220] The set distance between each two adjacent protrusions 141a may be equal or unequal, and as can be understood, when the side impact reinforcement beam 14 is used as the mounting beam 141, the set distance between each two adjacent protrusions 141a is equal to ensure uniform support of the mounting material.

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

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

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

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

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

[0226] The battery cavity s1 and the high-pressure cavity s2 being provided independently of each other means that the battery cavity s1 and the high-pressure cavity s2 are sealed from each other. In order to provide the battery cavity s1 and the high-pressure cavity s2 independently, the battery cavity s1 and the high-pressure cavity s2 can be formed separately from two independent parts. For example, an independent first part and a second part are provided inside the housing 10, and the first part forms the battery cavity s1, and the second part forms the high-pressure cavity s2. Alternatively, a partition material is provided inside the housing 10, and the storage cavity s formed inside the housing 10 is partitioned into the independent battery cavity s1 and the high-pressure cavity s2. Alternatively, all the storage cavities s formed inside the housing 10 are battery cavities s1, and the high-pressure cavity s2 is formed by forming a high-pressure chamber 15 outside the housing 10, thereby making the battery cavity s1 and the high-pressure cavity s2 independent of each other.

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

[0228] In some embodiments, referring to Figures 11 to 13, the housing 10 further includes a high pressure chamber 15, in which a battery cavity s1 is formed within the main body 11, and the high pressure chamber 15 is located outside the main body 11 and surrounds and forms a high pressure cavity s2 by itself or together with the main body 11.

[0229] The high pressure chamber 15 can be structured as a housing 22, the interior of which is hollow to form the high pressure chamber 15 and to place the high pressure case in. By providing the high pressure chamber 15 outside the main body 11 and forming a battery cavity s1 with the main body 11 (in this case, the battery cavity s1 corresponds to the 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 the high pressure cavity s2 together with the main body 11, the high pressure chamber 15 has one opening and is attached to the main body 11 through this opening. When the high pressure chamber 15 itself forms the high pressure cavity s2 by surrounding it, there is only an attachment relationship between the high pressure chamber 15 and the main body 11.

[0231] At this time, a high-pressure cavity s2 is defined and formed by a high-pressure chamber 15 provided outside the main body 11, and the storage cavity s formed by the main body 11 can be used as a battery storage cavity s1 to store a single battery 20, thereby improving the electrical capacity of the battery 100.

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

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

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

[0235] Of course, if the top of frame 11b is also configured as part of the top of main body 11, high-pressure chamber 15 may also be provided at the top of frame 11b, and may be specifically set depending on the mounting method between frame 11b and carrier 11a.

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

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

[0238] In one practical example, the high pressure chamber 15 has a top close to the main body 11 installed on the outer edge of one side in the rear direction of the vehicle 1000, that is, the high pressure chamber 15 is located close to the rear of the vehicle 1000, so that the high pressure chamber 15 can be arranged corresponding to the passenger space rear of the driving space of the vehicle 1000, and in particular, can be arranged corresponding to under the seat 300 of the passenger space, without occupying the activity space of the vehicle 1000.

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

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

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

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

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

[0244] At this time, a high-pressure cavity s2 is formed by the chamber case 15b, the high-pressure cavity s2 is sealed by the chamber lid 15a, 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] Fig. 17 is a schematic diagram showing a structure of a part of a battery 100 in some other embodiments of the present application, Fig. 18 is a side view of the structure shown in Fig. 17, Fig. 19 is an exploded view of the structure shown in Fig. 18, and Fig. 20 is a cross-sectional view of the EE portion of the structure shown in Fig. 18. Fig. 21 is a plan view of the structure shown in Fig. 17.

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

[0247] In a conventional vehicle 1000, a middle passage beam 16 is generally provided on the chassis of the body 200 of the vehicle 1000, and the middle passage beam 16 is a beam structure extending from the front chassis to the rear chassis in the body 200 of the vehicle 1000, and is a main structural member for ensuring the collision transmission path of the body 200 and the rigidity of the bottom plate of the body 200. The middle passage beam 16 is disposed in the middle region of the chassis of the vehicle 1000, and extends from the front chassis to the rear chassis along the front-rear direction of the vehicle 1000.

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

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

[0250] The intermediate passage beam 16 may be a sheet metal member integrally formed by pressing, die casting, or the like, or may be a beam structure formed by welding, fusion, or fastening a plurality of sheet metal plates, as long as it can form the wire passage 16a of the wire passage. The wire passage 16a may be located inside the intermediate passage beam 16 (for example, a hole passage inside the intermediate passage beam 16) or outside the intermediate passage beam 16 (for example, a recessed groove passage recessed outside the intermediate passage beam 16). The intermediate passage beam 16 may form the wire passage 16a together with the main body 11, or may form the wire passage 16a by itself. The intermediate passage beam 16 and the main body 11 can be connected to each other by welding, fusion, fastening, or the like to be integrated.

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

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

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

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

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

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

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

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

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

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

[0261] To engage the wire harness in the wire passing groove 16a1, specifically, the cutout dimension of the wire passing groove 16a1 may be made equal to the diameter of the wire harness to be inserted therethrough, or the two may be tightly fitted together to engage the wire harness. Specifically, an engaging member may be provided in the cutout of the wire passing groove 16a1, one end of the engaging member may be rotatably connected to one side of the cutout of the wire passing groove 16a1, and the other end may be detachably engaged with the other side of the cutout of the wire passing groove 16a1, and after the wire harness is placed in the wire passing groove 16a1, the engaging member may be engaged with the cutout of the wire passing groove 16a1 to engage the wire harness in the wire passing groove 16a1.

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

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

[0264] The opening side of the wire passing groove 16a1 is the side where the notch of the wire passing groove 16a1 exists. The beam cover 162 is detachably covered on the opening side of the wire passing groove 16a1, that is, it is detachably connected to the beam seat 161. Specifically, the beam cover 162 is detachably engaged with the beam seat 161, or the beam cover 162 and the beam seat 161 realize a detachable connection by a fastener (e.g., a bolt). The method of realizing the detachable connection between the beam cover 162 and the beam seat 161 can adopt a general setting in the art, and it is not necessary to limit the description here.

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

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

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

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

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

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

[0271] The middle passage beam 16 generally corresponds to extending from the front chassis of the vehicle body 200 to the rear chassis of the vehicle body 200, and the high pressure chamber 15 is located on one side of the middle passage beam 16 in the first direction F1, and the high pressure chamber 15 can be disposed in front of or behind the middle passage beam 16. Specifically, the high pressure chamber 15 can be disposed behind the middle passage beam 16 corresponding to the position of the rear chassis of the vehicle body 200, and the position of the rear chassis of the vehicle body 200 can be used to mount the seat 300 of the passenger compartment of the vehicle 1000, so that the arrangement of the high pressure chamber 15 can be realized by hiding the high pressure chamber 15 in the space below the seat 300, and the space utilization rate of the passenger compartment of the vehicle 1000 can be improved.

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

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

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

[0275] Furthermore, the area size of the first region ha and the area size of the second region hb are not limited, and the first region ha and the second region hb may be flat or non-flat surfaces, and their specific configurations are not limited.

[0276] In one specific embodiment, for example, when the external device is the body 200 of the vehicle 1000, the mounting portion 13a3 is configured and formed in the second region hb, so that the housing 10 is connected to the body 200 through a relatively outer region of the top. In this case, the housing 10 receives only the vertical force of the body 200, which is advantageous in reducing the force transmission path and improving the rigidity and lateral pressure resistance of the entire vehicle.

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

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

[0279] Orthogonal projection is a projection in which a parallel projection line is projected perpendicularly to the projection surface, 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 receiving point whose geometric center orthogonally projected onto the second region hb is the mounting force receiving point, and the distance between two adjacent mounting force receiving points (i.e., distance L2) is limited to 80 to 500 mm, thereby making it possible to uniformly mount the battery 100 to the external device and improve the connection strength between the battery 100 and the external device.

[0280] In one specific embodiment, when the external device is the body 200 of the vehicle 1000, the mounting part 13a3 is installed to include a plurality of mounting holes k1, and the housing 10 of the battery 100 is connected to the body 200 through the plurality of mounting holes k1. The distance L2 between the geometric centers of the 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 and k1 is controllable, and by controlling the set distance between the mounting holes k1 and k1, a basically uniform distribution between the plurality of mounting positions on the housing 10 is ensured, so that the force received by the body 200 is uniform, and further, the connection rigidity between the body 200 and the housing 10 at each position is improved.

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

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

[0283] Distance L2 is within a range of 80 mm to 300 mm, that is, it is possible to ensure a uniform connection between battery 100 and an external device while also ensuring the strength of the connection between battery 100 and the external device.

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

[0285] The seal area hc is also part of the top surface h of the housing 10, and is located between the first region ha and the second region hb, separating the first region ha and the second region hb to form a non-communicating relationship. Its main role is to attach the seal 12 to isolate the first region ha and the second region hb from each other so that the area of ​​the seal area hc does not become excessively large, and it is set as close as possible to the size, volume and shape of the seal 12 to ensure that the entire seal 12 is assembled to the seal area hc.

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

[0287] In one specific embodiment, taking the external device as the body 200 of the vehicle 1000 as an example, the battery 100 may be attached to the bottom of the body 200 and sealed and connected to the body 200 by the seal 12 on the sealing area hc, in which case the first region ha forms the sealed interior of the body 200 and the second region hb is the exterior of the body 200, and fluids or solid particles etc. outside the body 200 cannot leak into the interior of the body 200, for example stones or liquids scattered during the running of the vehicle 1000 cannot collide with the interior of the body 200, thereby realizing the sealing property and structural reliability of the interior of the body 200.

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

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

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

[0291] The outer edge of the seal area hc is a common boundary line between the seal area hc and the second region hb, and of course the seal area hc also has an inner edge that is a 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 orthogonal projection of the mounting portion 13a3 in the second region hb and the outer edge of the seal area hc is the length of a perpendicular line drawn from the geometric center of each mounting portion 13a3 to the outer edge of the seal area hc to ensure that the distance between the seal 12 and the mounting portion 13a3 is within a specified range.

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

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

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

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

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

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

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

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

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

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

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

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

[0305] The above description can be used as a reference for an explanation of the holes in the circumferential side wall n of the main body 11, but we will not go into detail here. However, since the outer edge of the seal area hc close to the second region hb is not coplanar in the vertical direction with the plane on which the circumferential side wall n of the main body 11 is located, a certain reserve distance is also provided 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 not deformed, both side edges of the seal 12 overlap with the inner and outer side edges of the seal area hc, and when the seal 12 is sealed and connected to an external device, the seal 12 protrudes beyond the seal area hc on both sides, with one side extending beyond the seal area hc into the first region ha and the other side extending beyond the seal area hc into the second region hb.

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

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

[0309] The top surface h1 of the main body 11 is a surface of one side of the main body 11 located at the top thereof and separated from the receiving cavity s. When the housing 10 includes both the main body 11 and the side beam 13 in the above embodiment, the top surface h of the housing 10 may be defined and formed together with the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. In this case, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 can be arranged coplanarly, so that the contact area between the top surface h of the housing 10 and the external device is increased, which can contribute to improving the connection reliability between the housing 10 and the external device, and the top structure of the housing 10 can be made relatively flat to improve the 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 coplanar.

[0310] In other embodiments, the housing 10 may include other structures other than the main body 11 and the side beams 13, in which case the top surface h of the housing 10 is defined and formed together with the top surface h1 of the main body 11, the top surface h2 of the side beams 13, and the top surfaces of the other structures.

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

[0312] In some embodiments, with reference to FIGS. 11 and 13, at least a portion of the second region hb and the first region ha are located on the top surface h1 of the body 11.

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

[0314] As can be understood, the second region hb on the top surface h1 of the main body 11 is a reserve distance between the outer edge of the sealing area hc close to the second region hb and the circumferential side wall n of the main body 11, and ensures sufficient deformation space for the deformation of the sealing portion 12 to prevent the sealing portion 12 from overflowing beyond the top surface h1 of the main body 11 and onto the side beam 13 when the sealing 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] The mounting hole k1 is provided in the second region hb defined by the top surface h2, and has the beneficial effect that the mounting portion 13a3 is provided at the top of the side beam 13, so it is omitted here.

[0317] When the housing 10 includes both the main body 11 and the side beam 13 in the above embodiment, the top surface h of the housing 10 may be defined and formed together with the top surface h1 of the main body 11 and the top surface h2 of the side beam 13. A reserve distance is provided between the outer edge of the seal area hc near the second region hb and the axial side wall of the main body 11, so that a deformation space sufficient for deformation of the seal 12 can be secured, and it is possible to prevent the seal 12 from protruding beyond the top surface h1 of the main body 11 onto the top surface h2 of the side beam 13 during deformation and interfering with the mounting of the mounting portion 13a3 on the side beam 13.

[0318] In some embodiments, referring to FIG. 14, the mounting portion 13a3 is arranged on the first sub-beam 13a1 and / or the second sub-beam 13a2, and in the first direction F1 and / or the second direction F2, the distance L2 between the geometric centers of the orthogonal projections of two adjacent mounting portions 13a3 in the second region hb is 80 mm to 500 mm.

[0319] The first sub-beam 13a1 and the second sub-beam 13a2 are not described here because the above description can be referred to. The two first sub-beams 13a1 are extended in the first direction F1, the two second sub-beams 13a2 are extended in the second direction F2, and the first sub-beam 13a1 and / or the second sub-beam 13a2 are provided with mounting portions 13a3, respectively, and the mounting portions 13a3 are extended in the first direction F1 and / or the second direction F2, thereby uniformly mounting and fixing the external device in multiple directions and further improving the connection between the external device and the housing 10.

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

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

[0322] In one embodiment, the housing 10 includes the main body 11 having the battery cavity s1 formed therein, and the high pressure chamber 15 that is installed on the top of the main body 11, is located in the first region ha, and surrounds the main body 11 or together with the main body 11 to form the high pressure cavity s2. Since the first region ha forms most of the top region of the main body 11, by disposing the high pressure chamber 15 in the first region ha, the space utilization rate of the first region ha can be improved.

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

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

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

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

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

[0328] Meanwhile, according to some embodiments of the present application, with reference to Figures 3 and 4, the present application provides a battery 100 including the housing 10 described in any of the above embodiments and a battery unit 20 housed in the housing cavity s. Since the battery 100 includes the housing 10 described above, it has all of the beneficial effects of the housing 10 described above, and the description thereof will be omitted here.

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

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

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

[0332] In some embodiments, referring to Figures 10 and 20, the housing 10 includes a main body 11 that surrounds and forms a storage cavity s, the main body 11 includes a carrier 11a located at the top of the housing 10 and defining the storage cavity s, and the battery unit 20 is mounted on the carrier 11a.

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

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

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

[0336] The fact that the battery unit 20 is suspended from the carrier 11a means that the battery unit 20 is placed vertically below the carrier 11a and the weight of the battery unit 20 is borne by the carrier 11a. The manner in which the battery unit 20 is suspended from the carrier 11a may include directly adhering the battery unit 20 to the lower surface of the carrier 11a, connecting the battery unit 20 to the carrier 11a via a fastener so that the battery unit 20 is located below the carrier 11a, and suspending the battery unit 20 from the carrier 11a via a hook or the like so that the battery unit 20 is located below the carrier 11a.

[0337] At this time, the battery unit 20 is suspended below the carrier 11a, and the bottom cover 11c is located at the bottom of the housing 10, and 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, and particularly when the carrier 11a is receiving force as at least a part of the chassis of the vehicle 1000, it is only necessary to attach and detach the battery unit 20 from below the carrier 11a without removing the carrier 11a, making it easier to repair the battery 100.

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

[0339] Specifically, the battery unit 20 and the carrier 11a can be bonded with an adhesive such as an epoxy resin adhesive or an acrylic ester adhesive, but are not limited to this. In this case, the battery unit 20 and the carrier 11a are bonded, which not only makes the connection easier but also simplifies the structure of the battery 100.

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

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

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

[0343] The electrode terminal 21a is disposed on the outer surface of the battery unit 20 other than the first outer surface m1. The first outer surface m1 faces the carrier 11a and is a normal smooth surface on which structures such as the electrode terminal 21a and the liquid injection hole are not uneven. The first outer surface m1 is an 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 above-mentioned housing 22 and end cap 21, and the housing 22 and the end cap 21 form an internal environment in which the battery unit 20 accommodates the electrode assembly 23. The end cap 21 is located at one end of the housing 22, and the electrode terminal 21a is disposed on the end cap 21. In this case, any outer surface of the housing 22 can be the first outer surface m1 of the battery unit 20.

[0344] The electrode terminal 21a includes a positive electrode terminal electrically connected to the positive electrode sheet in the electrode assembly 23, and a negative electrode terminal electrically connected to the negative electrode sheet in the electrode assembly 23. The positive electrode terminal and the negative electrode terminal may be disposed on the same outer surface of the battery unit 20 (like a prismatic battery unit), or may be disposed on two different outer surfaces of the battery unit 20 (like a cylindrical battery unit). When the positive electrode terminal and the negative electrode terminal are disposed 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.

[0345] In addition to the single battery 20, the battery 100 usually includes components such as a sampling wire harness that electrically connects the single battery 20, a high-voltage wire harness, and a protective structure that protects the single battery 20. In this case, by arranging the electrode terminal 21a on a surface of the single battery 20 other than the first outer surface m1, when components such as the sampling wire harness, the high-voltage wire harness, and the protective structure are used for the electrode terminal 21a, each component can be arranged through a space between the single battery 20 and other structures of the main body 11 other than the carrier 11a (for example, a space between the single battery 20 and the bottom cover 11c, and / or a space between the single battery 20 and the inner surface of the main body 11) without being restricted by the carrier 11a, making it easier to arrange each component. 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 with each other, and the single battery 20 and the carrier 11a can be attached in close contact with each other. This eliminates the need to secure a spare space between the single battery 20 and the carrier 11a, which contributes to improving the space utilization rate of the battery 100.

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

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

[0348] Furthermore, the battery unit 20 and the bottom cover 11c can be installed with a gap between them, thereby preventing external forces acting on the bottom cover 11c from being transmitted to the battery unit 20 and damaging the battery unit 20. In particular, when the battery 100 is attached to the bottom of the vehicle 1000 and the bottom cover 11c is located at the lowest part of the battery 100, it is easy for stones and the like from the ground to fly into the bottom of the battery 100 and hit the bottom cover 11c while the vehicle 1000 is traveling. At this time, the buffer space can block the external force from being transmitted to the battery unit 20 and affecting it.

[0349] When the battery unit 20 is disposed at a distance from the bottom lid 11c, a buffer space is formed between the second outer surface m2 and the bottom lid 11c, where the electrode terminal 21a protrudes from the battery unit 20, and the wire harness and the connection piece connected to the electrode terminal 21a can be disposed in the buffer space. Meanwhile, as described above, the buffer space has a space that can prevent the battery unit 20 from being damaged by the external force that strikes the bottom lid 11c. This kills two birds with one stone, since the buffer space not only blocks the influence of the external force, but also enables the layout of the wire harness and the like. In addition, the spatial utilization rate of the buffer space and the battery 100 is improved.

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

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

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

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

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

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

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

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

[0358] The top of the bottom housing 10, where the chassis is located in the vehicle body 200, directly becomes at least a part of the chassis. That is, the top of the housing 10 is used to form at least a part of the chassis of the vehicle body 200. By integrating the top of the housing 10 integrally with the chassis of the vehicle body 200 in this manner, the space occupied by the gap between the conventional chassis and the battery 100 is divided into a space that expands the battery 100 within the battery 100, thereby improving the energy of the battery 100 and improving the driving capability of the vehicle 1000.

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

[0360] The components of the above-described embodiments may be combined in any manner. For the sake of brevity, not all possible combinations of the components in the above-described embodiments have been described. However, as long as there is no contradiction in the combinations of these components, they should all be considered to be within the scope described in this specification.

[0361] The above embodiments are merely representative of some embodiments of the present application, and the description is specific and detailed, but it cannot be understood as limiting the scope of the patent of the present application. It should be noted that those skilled in the art can make some modifications and improvements without departing from the concept of the present application, and all of them belong to the scope of protection of the present application. Therefore, the scope of protection of the present application should be subject to the scope of the appended claims. [Explanation of symbols]
