Description

[Technical Field]

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

[0002] With the development of new energy technology, new energy vehicles are gradually coming into people's sights. The main core technology of new energy vehicles is the battery, and the safety and stability of the battery directly determine the overall performance of the vehicle.

[0003] A vehicle typically includes a body and a battery mounted on the body, and the battery typically includes a housing and battery cells mounted within the housing. When the housing is mounted on the body, the battery and body are subjected to multi-directional forces, reducing the overall rigidity of the body and its ability to resist lateral pressure. Summary of the Invention

[0004] In view of this, the present application provides a battery and an electric device, which reduces the force transmission path of the battery and the vehicle body, and reduces the overall vehicle load. rigidity The purpose is to improve the ability to resist lateral pressure.

[0005] In a first aspect, the present application provides a housing having an accommodating cavity for accommodating a battery cell and a top surface facing away from the accommodating cavity, the top surface of the housing being formed with a first region, a second region, and a sealing zone located between the two, the sealing zone surrounding the first region and being used for attaching a sealing member, the second region being configured with a mounting portion, the battery being attached to an external device via the mounting portion and bringing the sealing member into contact with the external device, the sealing zone being located on the same plane as the second region, thereby ensuring that the mounting force receiving points of each mounting portion are on the same plane and at the same height as the sealing zone, and both the mounting force receiving points and the sealing member are subjected to vertical forces, thereby reducing the forces received by the lateral structure of the housing and improving vehicle rigidity.

[0006] In some embodiments, the first area, the second area, and the sealing zone are located on the same plane, and in this case, the plane on which the first area, the second area, and the sealing zone are located is in contact with the external device, so that the contact area between the top surface of the housing and the external device is relatively large, which contributes to improving the connection reliability between the housing and the external device, and the top structure of the housing is flat, improving the aesthetics, and further reducing the force applied to the lateral structure of the housing.

[0007] In some embodiments, the mounting portion includes at least one mounting hole provided in the top of the housing, the mounting hole penetrating the second region, and when connecting the housing to an external device, a connecting member can be connected to the top of the housing at the second region of the outer periphery of the top of the housing to increase the connection strength between the housing and the external device.

[0008] In some embodiments, the housing further includes a sealing member, and the sealing member is attached to the sealing zone, in which case the battery housing realizes a sealed connection with an external device through the sealing member, seals and isolates the first region from the second region, and provides a reliable seal at low cost.

[0009] In some embodiments, the housing includes a body that surrounds and forms a receiving cavity, a top surface of the body defining at least a portion of the top surface of the housing, and the first region and the sealing zone located on the top surface of the body.

[0010] The top surface of the body may be divided into a first region and a sealing zone provided around the periphery of the first region, the first region forming a sealed body interior to achieve a sealed connection between the body and the body.

[0011] In some embodiments, the housing includes side beams, the main body having a circumferential sidewall disposed around a top outer edge thereof, the side beams being disposed on the circumferential sidewalls, and the top surface of the main body and the top surfaces of the side beams collectively defining the top surface of the housing. The side beams are disposed on the circumferential sidewalls of the main body, strengthening the lateral structural strength of the main body and further improving the lateral compressive resistance of the housing and the vehicle.

[0012] In some embodiments, the mounting portion is located in a second region defined by the top surfaces of the side beams. Because the mounting portion is located on the side beams, and the side beams do not define the accommodating cavity, the mounting portion can be positioned without having to consider its effect on the sealing of the accommodating cavity, improving the flexibility of the mounting portion placement. Furthermore, the side beams are located on the lateral edges of the housing. In this case, by locating the mounting portion on the side beams, the working space for attaching the housing to an external device is increased, improving convenience.

[0013] In some embodiments, there is a predetermined distance between an outer edge of the sealing zone proximate the second region and the circumferential sidewall of the body.

[0014] By providing a predetermined distance between the outer edge near the second region of the sealing zone and the circumferential side wall of the main body, sufficient deformation space can be secured for the deformation of the sealing member, and it is possible to prevent the sealing member from spilling over the top surface of the main body into other regions of the top of the housing and interfering with the structure of other regions.

[0015] In some embodiments, the side beam includes at least two sub-beams, the sub-beams being spaced apart sequentially along the circumferential sidewall, the top surface of each sub-beam defining a portion of the top surface of the side beam, and the sub-beams being provided with a mounting portion.

[0016] The arrangement of the sub-beams improves the vehicle's lateral pressure resistance capability and improves the vehicle's safety performance, and by installing mounting parts on all of the symmetrically installed sub-beams, it is possible to ensure uniformity of the force received by the mounting parts.

[0017] In some embodiments, the body includes a support member and a frame, the frame defining a cavity having at least a top end extending therethrough, the support member mating with the top end of the cavity, the support member and the frame surrounding the cavity to form at least a portion of the cavity, and the side beams being provided on circumferential side walls defined by the frame.

[0018] In this way, a mounting base is formed for mounting the battery cells and side beams.

[0019] In a second aspect, the present application provides a battery including the above-described housing and a battery cell, wherein the battery cell is housed within the housing.

[0020] In some embodiments, the housing includes a main body that surrounds and defines a storage cavity, the main body includes a support member located at the top of the housing and defining the storage cavity, and the battery cells are mounted on the support member. The battery cells are mounted below the support member and, together with the support member, receive a force from the top of the battery housing, thereby increasing the rigidity of the top of the battery housing.

[0021] In some embodiments, the battery cells are suspended on a support member, the battery cells are suspended below the support member, and the bottom cover is located at the bottom of the housing, so that when performing maintenance on the inside of the battery, it is not necessary to remove the support member, and the battery cells can be exposed by simply removing and attaching the bottom cover, making battery maintenance more convenient. At the same time, when performing maintenance on the battery, the battery cells can be attached and detached to and from the support member from below, especially when the support member is subjected to force as at least a part of the chassis of the vehicle, so that the battery cells can be attached and detached from and from the bottom of the support member without removing the support member, making battery maintenance more convenient.

[0022] In some embodiments, the battery cells are bonded to the support member, and bonding the battery cells to the support member not only provides a convenient connection but also simplifies the structure of the battery.

[0023] In some embodiments, the outer surface of the battery cell facing the support member is a first outer surface, and the battery cell includes electrode terminals, which are located on an outer surface of the battery cell other than the first outer surface. In this case, the electrode terminals are located on an outer surface of the battery cell other than the first outer surface, and various components connected to each electrode terminal (e.g., a sampling wire harness, a high-voltage wire harness, a shielding structure, etc.) can be located using the space between the battery cell and the bottom cover and / or the space between the battery cell and the inner surface of the main body, making the arrangement of each component more convenient. In addition, in this case, by connecting the first outer surface, on which the electrode terminals are not located, to the support member, the battery cell and the support member can be bonded together, saving space between the battery cell and the support member and improving the space utilization rate of the battery.

[0024] In some embodiments, the battery cell has a second outer surface facing away from the first outer surface, and the electrode terminal is provided on the second outer surface. In this case, a buffer space is formed between the second outer surface and the bottom cover, and the portion of the electrode terminal protruding from the battery cell is located within the buffer space, allowing the wire harness and connection sheet connected to the electrode terminal to be placed within the buffer space. At the same time, the buffer space can also prevent external force from hitting the bottom cover from acting on the battery cell and damaging the battery cell. Therefore, the buffer space not only blocks the effects of external force but can also be used to route the wire harness, killing two birds with one stone.

[0025] In a third aspect, the present application further provides an electrical device comprising the battery described above, wherein the battery is used to supply electrical energy to the electrical device.

[0026] In some embodiments, the electrical device includes a vehicle, and the battery is located at the bottom of the vehicle body, whereby the battery does not occupy space inside the vehicle body and helps reduce the volume and weight of the vehicle body.

[0027] In some embodiments, the battery is connected to the vehicle body via the top of the housing, and the top of the housing is positioned to form at least a portion of the vehicle chassis, so that the space occupied by the gap between the traditional chassis and the battery is contained within the battery, increasing the battery space, thereby increasing the battery energy and further improving the vehicle's range.

[0043] In view of the above, in order to improve the rigidity and lateral pressure resistance of the entire vehicle, the inventor of the present application, after extensive research, has designed a housing for a battery, the interior of which can accommodate a battery cell, the housing having a top surface facing the accommodating cavity, the top surface being divided into a first region, a sealing zone and a second region, the sealing zone being used for attaching a sealing member, the sealing member being in sealing contact with the vehicle body, the second region being formed with a mounting part and fixedly connected to the vehicle body via the mounting part, the sealing zone being positioned on the same plane as the second region, ensuring that the mounting force receiving points of each mounting part are on the same plane and at the same height as the sealing zone, and the mounting force receiving points and the sealing member both bear vertical forces, so that the housing and the vehicle body are both subjected to vertical acting forces only.

[0044] The battery disclosed in the embodiments of the present application can be used in, but is not limited to, electric devices such as vehicles, ships, and aircraft. The battery disclosed in the present application may be used to form a power supply system for the electric device.

[0064] The main body 11 may be a one-piece structure or may be formed by assembling multiple parts. As can be understood, the main body 11 is a hollow shell structure that surrounds itself to form the receiving cavity s. Specifically, the main body 11 may be formed by assembling a first sub-part (not shown) and a second sub-part (not shown), but this is not limiting. In one example, the first sub-part surrounds and forms the receiving cavity s with an open end, and the second sub-part covers the opening of the receiving cavity s. In another example, the first sub-part surrounds and forms a first space with an open end, and the second sub-part surrounds and forms a second space with an open end, and the two open portions of the first sub-part and the second sub-part cover each other to form the receiving cavity s consisting of the first space and the second space. The first sub-part and the second sub-part may be welded, latched, or fastened. The first and second sub-portions may be made of plastic, metal, or other materials.

[0065] In some embodiments, referring to FIG. 4, the top of body 11 forms at least a portion of the top of housing 10.

[0066] The top of the main body 11 refers to the structure located at the top of the main body 11 in the vertical direction, and since the top of the main body 11 is the top of the housing 10, 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 also the top of the housing 10, and the entire top of the housing 10 participates in the definition of the storage cavity s. As will be described in more detail below, when the top of the main body 11 forms a part of the top of the housing 10, the top of the housing 10 includes other structures that do not participate in the definition of the storage cavity s, such as the side beams 13 described below.

[0067] When the battery 100 is attached to an external device via the top of the housing 10, the top of the main body 11 is also the closest part of the battery 100 to the external device, and the distance between the top of the main body 11 and the external device means the vertical distance between the highest point of the top of the main body 11 and the external device above it.

[0068] As can be seen, with reference to Figure 6, the body 11 has a circumferential sidewall n disposed around the outer edge of its top.

[0069] The main body 11 has a top portion at the top in the vertical direction, and of course also has a bottom portion at the bottom, of which the bottom portion may have a bottom surface and a structure provided on the bottom surface, or the bottom surface may be open.

[0070] The outer surface facing away from the storage cavity s sandwiched between the top and bottom forms a circumferential sidewall n, and the extension direction of the surface on which the circumferential sidewall n is located is arranged to intersect with the surface on which the top is located. As will be described in detail later, the circumferential sidewall n may be annular, rectangular, or the like, formed by connecting multiple wall sections front to back.

[0071] As can be seen, with reference to FIG. 6, the housing 10 further comprises a top surface h opposite the receiving cavity s.

[0072] The top surface h of the housing 10 is located on the side opposite 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 so as to face the external device and be at the position of the battery 100 closest to the external device.

[0073] In some embodiments, referring to FIG. 6, the top surface h of the housing 10 is disposed so as to be in contact with an external device (not shown) to which the battery 100 is attached.

[0074] By attaching the battery 100 to the external device via the top of the housing 10 and bonding the surface of the housing 10 facing away from the storage cavity s so that it is in contact with the external device, the battery 100 is tightly attached to the external device, and the connection structure between the housing 10 and the external device is smaller, less expensive, and more compact than in an arrangement in which the top surface h of the housing 10 is not in contact with the external device.

[0075] In some embodiments, referring to FIG. 6, a mounting portion 13a3 is formed on the top of the housing 10, and the battery 100 is attached to an external device via the mounting portion 13a3.

[0076] The mounting portion 13a3 is not involved in the partitioning of the storage cavity s as part of the top of the housing 10. The mounting portion 13a3 refers to a dedicated structure provided on the top of the housing 10 for connecting to a connecting member (e.g., a bolt, a rivet, etc.) of an external device, and in order to securely connect the battery 100 to the external device, the connecting member has one end connected to the mounting portion 13a3 and the other end connected to the external device. Device As can be understood, since the top of main body 11 is at least a part of the top of housing 10, mounting portion 13a3 may be provided on the top of main body 11 or on another structure that constitutes the top of housing 10 (for example, the top of side beam 13 described below).

[0077] When the battery 100 is attached to an external device via the mounting portion 13a3, the top surface h of the housing 10 is connected so as to come into contact with the external device, thereby improving the connection strength and ensuring a compact connection structure between the housing 10 and the external device.

[0078] The mounting portion 13a3 may have a connecting function (such as a hanging ring) itself, or a corresponding connecting member (such as a hook) may be provided on an external device to directly connect the mounting portion 13a3 to the external device. In other embodiments, a connecting member may not be provided, and the mounting portion 13a3 may be directly connected to the external device in other ways, including, but not limited to, locking connection, plug connection, screw connection, rivet connection, welding, adhesive connection, etc., and the present application does not specifically limit the scope of the present invention.

[0079] 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.

[0080] The mounting holes k1 may be formed on the top of the housing 10 by drilling, and inside all of the mounting holes k1, holes and openings communicating with both ends of the holes are formed, and the holes and openings communicating with both ends of the holes allow the insertion of connecting members and realize fixation to the structure in which the mounting holes k1 are provided, thus realizing connection between the external device and the top of the housing 10 via the connecting members.

[0081] The connecting member may be a rivet, a fixing hole 11c3 may be provided at a position corresponding to the mounting hole k1 of the external device, and the rivet may be passed through the fixing hole 11c3 and the mounting hole k1, and then the two may be fixed together with a nut. Alternatively, the connecting member may be a screw, the mounting hole k1 may be a threaded hole, and the screw may be passed through the mounting hole k1 and connected to the housing 10 by a screw connection.

[0082] Specifically, the mounting holes k1 may all extend vertically to secure the battery 100 to the bottom of the external device in a vertical direction. As can be appreciated, factors such as the placement locations and placement distances of the mounting holes k1 may be controlled to achieve stable connection between the top of the housing 10 and the external device and uniformity of the forces applied to both, as will be described in detail below.

[0083] As can be understood, the mounting portion 13a3 may further include other mounting structures, such as hooks, in addition to the mounting holes k1.

[0084] In some embodiments, referring to Figures 4 and 6, the main body 11 includes a support member 11a and a frame 11b, the frame 11b surrounding the cavity with at least a top end thereof extending therethrough, the support member 11a covering the top end of the cavity, and the support member 11a and the frame 11b surrounding the cavity forming at least a portion of the receiving cavity s.

[0085] The frame 11b itself encloses a cavity having at least its top end penetrating therethrough, and the support member 11a covers the top of the cavity; that is, the support member 11a is located at the top of the housing 10 and defines the receiving cavity s. The frame 11b and the support member 11a may be made of the same material, such as an aluminum alloy, a copper alloy, a steel material, or a plastic. Of course, the frame 11b, the support member 11a, and the bottom cover 11c may be made of different materials, and the specific shape is not limited thereto. When projected vertically orthogonally, the frame 11b may have a rectangular, circular, polygonal, or other shape, and the specific shape is not limited thereto. The support member 11a may be a carrier plate, a carrier sheet, a carrier block, or other structure.

[0086] The top surface h1 of the main body 11 may be entirely formed by the top surface of the support member 11a, in which case the entire frame 11b may be located below the support member 11a. The top surface h1 of the main body 11 may be jointly formed by the top surfaces of the support member 11a and the frame 11b, in which case the support member 11a is located inside the frame 11b, and the top surfaces of the support member 11a and the frame 11b may or may not be located on the same plane.

[0087] The support member 11a and the frame 11b are fixedly connected or integrally formed. The support member 11a and the frame 11b are integrally formed by injection molding, die casting, forging, cold pressing, hot pressing, etc. The support member 11a and the frame 11b may be fixedly connected by fastening with fasteners, a locking connection with an engaging structure, welding, adhesive bonding, heat welding, etc.

[0088] The circumferential side wall n of the main body 11 is mainly composed of the circumferential side wall n of the frame 11b, which is an outer surface that is arranged around the support member 11a and faces away from the cavity defined by it.

[0089] In some embodiments, referring to Figures 4 and 5, the main body 11 further includes a bottom cover 11c, and the bottom cover 11c, the support member 11a, and the frame 11b collectively surround and form a storage cavity s that stores the battery cell 20.

[0090] As can be seen, the cavity in the frame 11b further penetrates the bottom of the frame 11b, and the bottom cover 11c covers the bottom of the frame 11b and forms the receiving cavity s of the housing 10 together with the frame 11b and the support member 11a.

[0091] Specifically, the bottom cover 11c may have a plate-like structure, a block structure, or the like, but is not limited thereto, and may also have a flat plate-like structure, a curved plate-like structure, or the like, but is not specifically limited thereto. When the battery cell 20 is positioned in the accommodating cavity s, the battery cell 20 may be provided on the bottom cover 11c and / or the support member 11a and / or the frame 11b.

[0092] The bottom cover 11c and the frame 11b may be fixed to each other by welding, heat welding, adhesive bonding, fastening, locking, etc. Fastening refers to a connection achieved using fasteners 11c4, including bolts, pins, rivets, studs, screws, etc. Locking refers to a connection achieved by an engagement structure, such as a hook on the bottom cover 11c and a bayonet on the frame 11b, where the hook engages with the bayonet to achieve the engagement and fixation between the bottom cover 11c and the frame 11b. Of course, the connection between the bottom cover 11c and the frame 11b is not limited to this, and is not covered by this application.

[0093] In this case, when the frame 11b is used as a base and the support member 11a and bottom cover 11c are connected to both vertical ends of the frame 11b, a cavity s for accommodating the battery 100 is formed, and the structure of the main body 11 is relatively simple.

[0094] In some embodiments, referring to Figures 4 and 5, the bottom cover 11c comprises a cover portion 11c1 and an attachment portion 11c2, the attachment portion 11c2 being connected to the edge of the cover portion 11c1 in a surrounding manner, the cover portion 11c1 being used to define the storage cavity s, and the attachment portion 11c2 being connected to the frame 11b.

[0095] The term "lid portion 11c1 is used to define the receiving cavity s" means that the lid portion 11c1, together with the support member 11a and the frame 11b, forms the receiving cavity s, while the mounting portion 11c2 is connected to the frame 11b and does not contribute to the definition of the receiving cavity s. The lid portion 11c1 may be a plate-like or block-like member, or a flat or curved plate-like member, and is not particularly limited. As can be seen from FIGS. 4 and 5, the mounting portion 11c2 surrounding the edge of the lid portion 11c1 means that the mounting portion 11c2 is provided along the edge of the lid portion 11c1 to form a continuous structure that is tightly closed and connected. As can be seen, the mounting portion 11c2 has a certain width when projected vertically, which allows for an appropriate contact area between the mounting portion 11c2 and the frame 11b and facilitates the positioning and installation of the mounting portion 11c2 and the frame 11b.

[0096] The lid portion 11c1 and the mounting portion 11c2 may be integrally molded. When the bottom lid 11c is made of a metal material (e.g., aluminum, iron, stainless steel, etc.), the lid portion 11c1 and the mounting portion 11c2 may be integrally molded by means of die casting, forging, hot pressing, cold pressing, or the like. When the bottom lid 11c is made of a plastic material (e.g., polypropylene, polyethylene, ABS (Acrylonitrile Butadiene Styrene plastic), etc.), the lid portion 11c1 and the mounting portion 11c2 may be integrally molded by injection molding. The lid portion 11c1 and the mounting portion 11c2 may be molded separately and then connected. When the lid portion 11c1 and the mounting portion 11c2 are made of a metal material, 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 a plastic material, the lid portion 11c1 and the mounting portion 11c2 may be bonded. Of course, the cover portion 11c1 and the mounting portion 11c2 can also be fixedly connected by other means such as a locking connection or a rivet connection.

[0097] The lid portion 11c1 and the mounting portion 11c2 may be located on the same plane. Specifically, optionally, the two surfaces of the lid portion 11c1 and the mounting portion 11c2 that face the support member 11a are located on the same plane, and / or the two surfaces of the lid portion 11c1 and the mounting portion 11c2 that face away from the support member 11a are located on the same plane. When the two surfaces of the lid portion 11c1 and the mounting portion 11c2 that face the support member 11a and the two surfaces that face away from the support member 11a are located on the same plane, respectively, the lid portion 11c1 and the mounting portion 11c2 can form a flat bottom lid 11c.

[0098] The lid portion 11c1 and the mounting portion 11c2 do not have to be located on the same plane. Specifically, the lid portion 11c1 may be recessed toward the support member 11a relative to the mounting portion 11c2, or the lid portion 11c1 may protrude away from the support member 11a relative to the mounting portion 11c2, but this is not particularly limited. The thicknesses of the lid portion 11c1 and the mounting portion 11c2 may be the same or different, and are not particularly limited.

[0099] In this case, the bottom cover 11c defines the receiving cavity s via the cover portion 11c1 and is connected to the frame 11b via the mounting portion 11c2, resulting in a clear structure and convenient installation.

[0100] As can be understood, when bottom cover 11c is detachably connected to frame 11b, bottom cover 11c is detachably connected to frame 11b via attachment portion 11c2, that is, attachment portion 11c2 is detachably connected to frame 11b. As a method for detachably connecting attachment portion 11c2 to frame 11b, the portion of bottom cover 11c detachably connected to frame 11b may be defined as attachment portion 11c2.

[0101] In some embodiments, the mounting portion 11c2 is detachably connected to the frame 11b.

[0102] Specifically, the bottom cover 11c further includes a fixing hole 11c3 provided in the mounting portion 11c2, and the fastener 11c4 is fastened to the frame 11b after drilling the fixing hole 11c3 in the mounting portion 11c2. The fixing hole 11c3 is a through-hole that passes through the mounting portion 11c2 in the vertical direction. Specifically, the fixing hole 11c3 may be a smooth through-hole (e.g., when the fastener 11c4 is a rivet), a threaded through-hole (e.g., when the fastener 11c4 is a screw), or a through-hole of another shape (e.g., a hexagonal hole, a square hole, a constricted hole, etc.). The specific shape of the fixing hole 11c3 varies depending on the specific shape and setting method of the fastener 11c4, and therefore will not be described again here.

[0103] In some embodiments, referring to FIGS. 6, 8 and 9, the housing 10 includes side beams 13, which are provided on the circumferential sidewalls n of the body 11.

[0104] The side beams 13 refer to beam structures provided on the circumferential side walls n of the main body 11 to reinforce the strength of the main body 11. As can be understood, the side beams 13 are located outside the main body 11. Specifically, the main body 11 and the side beams 13 may be integrally connected or integrally connected by an assembly method. The integral connection method includes, but is not limited to, welding, integral molding, welding, etc. The assembly connection method includes, but is not limited to, a locking connection, a fastening connection, etc.

[0105] The side beams 13 may be provided over the entire circumferential side wall n of the main body 11, or may be provided locally on the circumferential side wall n of the main body 11. Optionally, the side beams 13 are provided around the circumferential side wall n of the main body 11, thereby strengthening the strength of the main body 11 from multiple lateral directions of the main body 11. Specifically, the side beams 13 are provided continuously or discontinuously around the circumferential side wall n of the main body 11. If provided continuously, the side beams 13 may be annular beams, and if provided discontinuously, the side beams 13 may include multiple beam portions spaced apart around the circumferential side wall n of the main body 11.

[0106] In actual use, the housing 10 is used for the battery 100, and the battery 100 is used for the vehicle 1000, with the top of the housing 10 attached to the vehicle 1000 and forming the chassis structure of the vehicle 1000. When the battery 100 housing 10 is used as the chassis of the vehicle 1000, the lateral structure of the housing 10 is susceptible to being pressed by an external impact (for example, a stone flying off while the vehicle 1000 is traveling strikes the housing 10 in a lateral direction, or a lateral impact from another vehicle 1000). In this case, side beams 13 are provided on the lateral peripheral walls of the main body 11, which strengthen the lateral structural strength of the main body 11 and further improve the lateral pressure resistance of the housing 10 and the lateral pressure resistance of the vehicle 1000, thereby improving the safety of the vehicle 1000.

[0107] As can be seen, when the body 11 includes the support member 11a and the frame 11b, the side beams 13 are provided on the circumferential side wall n defined by the frame 11b.

[0108] The cavity formed by the frame 11b mainly constitutes the storage cavity s of the housing 10, and because the storage cavity s has a fixed height to accommodate multiple battery cells 20, the frame 11b also has a fixed height, and therefore the circumferential side wall n of the frame 11b has a relatively large area. In this case, the side beams 13 are provided on the circumferential side wall n defined by the frame 11b, improving the flexibility of the mounting method, mounting area, and arrangement method of the side beams 13.

[0109] Furthermore, in the embodiment, the side beam 13 and the frame 11b are fixedly connected or integrally formed. The side beam 13 and the frame 11b may be fixedly connected by means of welding, melting, riveting, screwing, etc., or may be integrally formed by integral processing (e.g., stamping, die casting).

[0110] When the side beams 13 and the frame 11b are integrally molded, the assembly process of the housing 10 is reduced, accelerating the production process of the housing 10. When the side beams 13 and the frame 11b are fixedly connected, the molding process of the side beams 13 and the frame 11b is simple, and the process cost of the housing 10 can be reduced.

[0111] 10, in some embodiments, the side beam 13 includes at least two sub-beams 13a, which are spaced apart sequentially around the circumferential side wall n. The sub-beams 13a are base units that make up the side beam 13, and positioning the sub-beams 13a increases the degree of freedom in arranging the position of the side beam 13 on the circumferential side wall n of the main body 11.

[0112] The side beam 13 is formed by arranging at least two sub-beams 13a at intervals around the circumferential side wall n of the main body 11, which means that at least two sub-beams 13a are arranged at intervals around the extension direction of the circumferential side wall n to form an enclosing shape that surrounds the main body 11 and strengthens the strength of the main body 11 from multiple lateral directions of the main body 11.

[0113] The sub-beams 13a may have various structures, and the structures of the sub-beams 13a may be the same or different. For example, the sub-beams 13a are solid beams that extend vertically. For another example, the sub-beams 13a are hollow beams that extend vertically. The cross-sectional shape of each sub-beam 13a may be H-shaped, U-shaped, or other structural shapes.

[0114] In this case, the side beam 13 is formed by combining multiple sub-beams 13a, which increases the degree of freedom in arranging the side beam 13 and allows the individual sub-beams 13a to be attached one by one during installation. Compared to a one-piece side beam 13, this makes positioning during installation more convenient and labor-saving.

[0115] 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, which are spaced apart vertically and both connected to the main body 11.

[0116] The up-down direction corresponds to the direction in which the top and bottom of the main body 11 are located, that is, the upper arm beam 131 is closer to the top of the main body 11, and the lower arm beam 132 is closer to the bottom of the main body 11. As can be understood, the upper arm beam 131 and the lower arm beam 132 both extend along the circumferential direction of the main body 11 and are attached to the circumferential side wall n of the main body 11. The upper arm beam 131 and the lower arm beam 132 are provided with a gap therebetween, and are connected by the main body 11. A hole may be formed in the center of the gap between them, and the hole may be a lightweight structure or a structure for running a wire harness.

[0117] In this case, the structure of the main body 11 is strengthened by the upper arm beam 131 and the lower arm beam 132, and because the upper arm beam 131 and the lower arm beam 132 are spaced apart, the impact force received by the housing 10 can be dispersed, and the external force received by each part of the housing 10 becomes more uniform. At the same time, because the upper arm beam 131 and the lower arm beam 132 are spaced apart from each other vertically, the sub-beam 13a can withstand pressure from the front-rear or left-right directions of the vehicle 1000, and can be more adapted to the actual usage conditions of the vehicle 1000. In addition, the configuration in which the upper arm beam 131 and the lower arm beam 132 are spaced apart reduces the weight of the housing 10 and can achieve other functions.

[0118] In another embodiment, a central beam (not shown) may be provided between the upper arm beam 131 and the lower arm beam 132, and the central beam may be connected between the upper arm beam 131 and the lower arm beam 132, thereby further strengthening the structural strength of the sub-beams 13a and increasing the lateral pressure resistance capability of the housing 10.

[0119] 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 interior of the beam is hollow, i.e., the interior of the beam has a space that is not filled with any solid material. In this case, the upper arm beam 131 and the lower arm beam 132 have a hollow beam structure, which not only reduces the weight of the upper arm beam 131 and the lower arm beam 132 but also further alleviates the problem of high energy consumption due to the heavy weight of the battery 100 itself when the battery 100 formed from the housing 10 is applied to an electric device such as a vehicle 1000. Furthermore, the hollow beam structure dissipates lateral pressure due to the internal space, reducing the degree of damage to the battery 100 when subjected to lateral pressure.

[0120] In some embodiments, referring to FIG. 6, the circumferential side wall n includes at least two first wall sections n1, both extending along the first direction F1 and spaced apart, and the at least two sub-beams 13a include two first sub-beams 13a1, each of which is provided in one of the two first wall sections n1 and both extending along the first direction F1.

[0121] In one practical application, when the battery 100 formed from the housing 10 is used in a vehicle 1000 and the top of the housing 10 forms the chassis of the vehicle 1000, the first direction F1 may correspond to the front-to-rear direction of the vehicle 1000. The first wall sections n1 in the circumferential side walls n of the main body 11 correspond to the two circumferential side walls n in the left and right directions of the battery 100. The first wall sections n1 extend along the first direction F1, i.e., along the front-to-rear direction of the vehicle 1000. The two first wall sections n1 are spaced apart in the left-to-right direction of the vehicle 1000. Both of the two first wall sections n1 are provided with sub-beams 13a, and each sub-beam 13a and each first wall section n1 have the same extension direction.

[0122] The sub-beams 13a on each first wall section n1 may have the same structure, thereby ensuring uniform pressure resistance on both the left and right sides of the vehicle 1000. Furthermore, the sub-beams 13a on the first wall section n1 include the upper arm beams 131 and lower arm beams 132 mentioned in the above embodiment, in which case the sub-beams 13a have a relatively strong pressure resistance, which compensates for the weak structure on both the left and right sides of the vehicle 1000, strengthening the pressure resistance on both the left and right sides of the vehicle 1000 and improving the safety of the vehicle 1000.

[0123] In this case, providing sub-beams 13a in each first wall section n1 strengthens the structural strength of each first wall section n1, increasing the compressive resistance capacity of each first wall section n1, i.e., increasing the left and right compressive resistance capacity of the vehicle 1000, and as can be seen, since each sub-beam 13a extends along the first direction F1, further improving the bending resistance capacity of the vehicle 1000 in the fore-and-aft direction.

[0124] In some embodiments, still referring to FIG. 6, the circumferential sidewall n further includes two spaced apart second wall sections n2 extending along a second direction F2 perpendicular to the first direction F1, the two first wall sections n1 and the two second wall sections n2 being alternately connected, and the at least two sub-beams 13a include two second sub-beams 13a2, and the two second sub-beams 13a2 are respectively provided in the two second wall sections n2, and both are 2 Direction F2 It is provided extending along.

[0125] In practical applications, the second direction F2 may correspond to the left-right direction of the housing 10. In this case, the second wall section n2 corresponds to the circumferential side walls n in the two directions, i.e., the front and rear, of the battery 100. The second wall section n2 extends along the second direction F2, i.e., extends along the left-right direction of the vehicle 1000.

[0126] The sub-beams 13a on each second wall section n2 may have the same structure, thereby ensuring uniform pressure resistance on both the front and rear sides. Furthermore, the sub-beams 13a on the first wall section n1 may include only the upper arm beam 131 described in the above embodiment. The upper arm beam 131 is located near the top of the main body 11. In this case, the sub-beams 13a have a relatively weak pressure resistance. Since the vehicle 1000 is typically provided with a pressure resistance structure such as a bumper in the front-rear direction, when the vehicle 1000 is subjected to a pressure in the front-rear direction, the pressure resistance effect is mainly achieved by the front and rear bumpers. In this case, the pressure resistance required for the sub-beams 13a of the second wall section n2 is weak, and a relatively simple sub-beam 13a structure may be adopted, thereby reducing the costs of the battery 100 and the vehicle 1000.

[0127] In this case, by arranging the sub-beams 13a in each second wall section n2, the structural strength of each second wall section n2 is strengthened, and the pushing resistance capacity of each second wall section n2 is increased, i.e., the left and right pushing resistance capacity of the vehicle 1000 is increased, and as can be seen, since each sub-beam 13a extends along the second direction F2, the left and right bending resistance capacity of the vehicle 1000 is further improved.

[0128] In some embodiments, still referring to FIG. 6, the side beam 13 further includes at least two first sub-beams 13a1 and at least two second sub-beams 13a2, both of which are arranged on the circumferential side wall n, the first sub-beams 13a1 extending along a first direction F1 and spaced apart from each other, and the second sub-beams 13a2 extending along a second direction F2 perpendicular to the first direction F1 and spaced apart from each other.

[0129] In this case, the sub-beam 13a provided in the first wall section n1 is the first sub-beam 13a1, and the sub-beam 13a provided in the second wall section n2 is the second sub-beam 13a2. The two first sub-beams 13a1 can strengthen the pressing resistance capability of the housing 10 in the left-right direction of the vehicle 1000, and the two second sub-beams 13a2 can strengthen the pressing resistance capability of the housing 10 in the front-rear direction of the vehicle 1000, thereby generally improving the pressing resistance capability of the vehicle 1000 in the lateral direction and improving the safety performance of the vehicle 1000.

[0130] In some embodiments, and with continued reference to FIG. 6, the top of the side beam 13 is configured with a mounting portion 13a3.

[0131] For an explanation of the mounting portion 13a3, please refer to the above content and will not be repeated here. In this case, by providing the mounting portion 13a3 on the top of the side beam 13, the housing 10 according to the present embodiment can be obtained by adding the side beam 13 to the structure of the housing 10. This significantly reduces modification costs. Moreover, because the mounting portion 13a3 is provided on the side beam 13, the side beam 13 does not affect the division of the receiving cavity s. Therefore, when providing the mounting portion 13a3, it is not necessary to consider the effect of the mounting portion 13a3 on the sealing of the receiving cavity s, thereby increasing the flexibility of the mounting portion 13a3 placement. Furthermore, since the side beam 13 is located on the lateral edge of the housing 10, and the mounting portion 13a3 is provided on the side beam 13, the working space when attaching the housing 10 to an external device is increased, making it more convenient.

[0132] In some embodiments, the mounting portion 13a3 includes at least one mounting hole k1 provided at the top of the side beam 13.

[0133] The mounting hole k1 is described above and will not be described again here. The mounting hole k1 is located at the top of the side beam 13, and the mounting portion 13a3 at the top of the side beam 13 also provides advantageous effects, so it will not be described again here.

[0134] In some embodiments, the top surface h1 of the main body 11 and the top surface h2 of the side beam 13 collectively define the top surface h of the housing 10.

[0135] The top surface h1 of the main body 11 refers to the outer surface of the main body 11 located at the top thereof and facing away from the accommodating cavity s, and the top surface h2 of the side beam 13 refers to the outer surface of the side beam 13 located at the top side thereof. In the case where the side beam 13 includes the upper arm beam 131 and the lower arm beam 132 according to the above embodiment, the top surface h2 of the side beam 13 refers to the outer surface of the upper arm beam 131 facing away from the lower arm beam 132.

[0136] When the housing 10 includes the main body 11 and side beams 13 according to the above embodiment, the top surface h of the housing 10 may be jointly defined by the top surface h1 of the main body 11 and the top surface h2 of the side beams 13. The top surface h1 of the main body 11 and the top surface h2 of the side beams 13 may be located on the same plane. In this case, the contact area between the top surface h of the housing 10 and the external device is large, improving the connection reliability between the housing 10 and the external device, and the top structure of the housing 10 is flat, improving the aesthetic appearance. Of course, the top surface h1 of the main body 11 and the top surface h2 of the side beams 13 do not have to be located on the same plane.

[0137] As can be understood, when the side beam 13 includes at least two sub-beams 13a, the top surface of each sub-beam 13a defines a portion of the top surface h2 of the side beam 13, and the sub-beams 13a are provided with mounting portions 13a3. The mounting portions 13a3 may be provided on only some of the sub-beams 13a, or on all of the sub-beams 13a. When the mounting portions 13a3 are provided on only some of the sub-beams 13a, the mounting portions 13a3 are provided on all of the symmetrically arranged sub-beams 13a to ensure uniformity of the force applied to the mounting portions 13a3. The symmetrically arranged sub-beams 13a may include two first sub-beams 13a1 according to the above embodiment, or two second sub-beams 13a2 according to the above embodiment.

[0138] In some embodiments, referring to Figures 6 and 10, a wiring portion 13a4 is formed on the outer wall of the housing 10, and the wiring portion 13a4 is located below the top surface h of the housing 10 and forms a wiring space for drilling a wire harness.

[0139] The outer wall of the housing 10 is an outer surface facing away from the inner surface that defines the storage cavity s in the housing 10. The routing portion 13a4 is located below the top surface of the housing 10, that is, the routing portion 13a4 is provided on the outer wall located below the top surface h of the housing 10. The outer wall located below the top surface h of the housing 10 itself includes a bottom surface and a side wall connecting the top surface h and the bottom surface.

[0140] When the housing 10 includes only the main body 11, the side walls of the housing 10 are the circumferential side walls n of the main body 11. When the housing 10 includes the main body 11 and the side beams 13, the side walls of the housing 10 include the circumferential side walls n of the main body 11 that are not covered by the side beams 13, and the surfaces of the side beams 13 that face away from the main body 11.

[0141] The wiring portion 13a4 is located outside the accommodating cavity s and provides a wiring space for passing a wire harness that electrically connects the battery cell and the electrical components. The specific form of the wiring space is not limited, and it need only have an inlet through which the wire harness enters and an outlet through which the wire harness exits, and the inlet and outlet may be the same opening. The wiring space may also be a wiring hole or a wiring groove k2.

[0142] Specifically, the wiring portion 13a4 is provided on the outer wall of the housing 10 in the circumferential direction, and in this case, the wire harness can be routed conveniently via the side surface of the housing 10. Specifically, the wiring portion 13a4 may be provided on the bottom surface of the housing 10, and in this case, the wire harness may be routed via the bottom of the housing 10.

[0143] In this case, by forming the wiring section 13a4 on the outer wall of the housing 10, the wire harness is routed through the wiring space formed by the wiring section 13a4, thereby effectively protecting the wire harness, and there is no risk that the wire harness will be pressed and deformed when the vehicle 1000 is pressed from the outside, causing unnecessary safety risks.

[0144] In a further embodiment, with continued reference to FIGS. 6 and 10, the routing portion 13a4 is provided on a side wall of the housing 10 adjacent to its own top surface h.

[0145] The sidewalls are outer surfaces that connect the top surface h and the bottom surface (the surface opposite to the top surface h) of the housing 10 itself. The routing portion 13a4 may be provided on only some of the sidewalls of the housing 10, for example, on one or two sidewalls of the housing 10 in the first direction F1, or on one or two sidewalls of the housing 10 in the second direction F2. Of course, the routing portion 13a4 may be provided on all of the sidewalls of the housing 10.

[0146] In this case, by arranging the wiring portion 13a4 on the side wall of the housing 10, the working space in the lateral direction of the housing 10 is large, which makes it easier to wire the wire harness.

[0147] In some embodiments, the wiring portion 13a4 is provided on two side walls adjacent to the top surface h of the housing 10 and facing back to back.

[0148] The two side walls adjacent to the top surface h of the housing 10 and facing each other include two side walls facing back to back in the first direction F1 and two side walls facing back to back in the second direction F2. In this case, the routing portion 13a4 may be provided symmetrically facing each other in the first direction F1, or may be provided facing each other in the second direction F2, and the wire harness can be routed simultaneously from both sides of the housing 10 in the first direction F1, or from both sides of the housing 10 in the second direction F2, thereby realizing a symmetrical arrangement of the wire harness, improving the aesthetic appearance of the wire harness arrangement, and contributing to the weight balance of the vehicle 1000.

[0149] Furthermore, the wiring portions 13a4 are provided on two side walls of the housing 10 in the second direction F2, i.e., on two side walls of the housing 10 corresponding to the left and right directions of the vehicle 1000. Because the various electric drive systems of the vehicle 1000 (used to provide forward power for the vehicle 1000) are mainly provided on the front or rear side, the wire harness is connected to the battery 100 and the electric drive systems mainly in the fore-and-aft direction of the vehicle 1000, and arranging the wiring portions 13a4 in this manner makes it easier to route the wire harness.

[0150] Regarding one specific embodiment, referring to FIGS. 6 and 10, the wiring portion 13a4 includes a wiring groove k2 formed in the outer wall of the housing 10 and recessed toward the receiving cavity s.

[0151] As can be seen, the wiring groove k2 is recessed toward the receiving cavity s to form a wiring space with one open side, and the open side faces the groove bottom of the wiring groove k2. The wiring groove k2 may be recessed toward the receiving cavity s and may further include a wire inlet and a wire outlet. Specifically, the wire inlet of the wiring groove k2 may be an opening at one end in the extension direction of the wiring groove k2, and the wire outlet of the wiring groove k2 may be an opening at the other end in the extension direction of the wiring groove k2.

[0152] When the routing groove k2 is located on the side wall of the housing 10 in the second direction F2, the routing groove k2 may be provided to extend along the first direction F1. When the routing groove k2 is located on the side wall of the housing 10 in the first direction F1, the routing groove k2 may be provided to extend in the second direction F2.

[0153] In this case, the wiring groove k2 has an opening, which makes it easier to drill the wire harness. Moreover, by configuring the recessed wiring groove k2 as the wiring portion 13a4, there is no need to add a structure to form another wiring space, which makes the structure of the housing 10 simpler and less expensive.

[0154] Of course, in other embodiments, the wiring portion 13a4 may have a structure including a wiring hole provided separately in the outer wall of the housing 10, such as a wiring bar including a wiring hole.

[0155] In some embodiments, referring to FIGS. 6 and 10, the side beam 13 forms a wiring portion 13a4.

[0156] Specifically, when the wiring portion 13a4 is the wiring groove k2, the side beam 13 may be composed of the upper arm beam 131 and the lower arm beam 132 according to the above embodiment, and the space between the upper arm beam 131 and the lower arm beam 132 is the space where the wiring groove k2 is located. Alternatively, the side beam 13 is recessed in a direction facing away from the outer surface of the main body 11 to form the wiring groove k2.

[0157] When the wiring portion 13a4 is a wiring hole and the side beam 13 penetrates along both ends in its extension direction to form a hollow beam, the internal space of the side beam 13 may form the wiring hole. Alternatively, the side beam 13 includes the upper arm beam 131, the lower arm beam 132, and the central beam (not shown) in the above embodiment, and the central beam, the upper arm beam 131, and the lower wall beam collectively surround the wiring hole.

[0158] In this case, the wiring portion 13a4 forms the side beam 13, that is, the side beam 13 has a wiring space, and the wiring space not only reduces the weight of the side beam 13 but also enables wiring, killing two birds with one stone.

[0159] In a specific embodiment, the upper arm beam 131 and the lower arm beam 132 jointly constitute the wiring section 13a4 having a wiring space. In this case, the wiring space is the space between the upper arm beam 131 and the lower arm beam 132, and the structure of the wiring section 13a4 is simple, killing two birds with one stone.

[0160] Fig. 11 is a schematic diagram of the local structure of a battery 100 in another embodiment 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 of the structure shown in Fig. 12. Fig. 15 is a schematic diagram of a usage scene of the structure shown in Fig. 11, and Fig. 16 is a side view of the structure shown in Fig. 14.

[0161] In some embodiments, referring to FIG. 11, the housing 10 further includes a sealing member 12 provided at the top of the housing 10 for a sealed connection with an external device.

[0162] The sealing member 12 refers to a component that can prevent fluids, solid particles, etc. from leaking out from between adjacent joining surfaces. The sealing member 12 is provided on the top of the housing 10 and divides the top of the housing 10 into an external area located on the outer periphery of the sealing member 12 and an internal area surrounded by the sealing member 12. The sealing member 12 seals between the two surfaces of the top of the housing 10 that face the external device and forms a contact interface between these two surfaces, thereby achieving a sealing effect by preventing fluids, solid particles, etc. in the external area located on the outer periphery of the sealing member 12 from entering the internal area surrounded by the sealing member 12 through the contact interface between itself and the two surfaces.

[0163] The sealing member 12 may optionally be a seal ring or a gasket. Specifically, the sealing member 12 may be made of a material such as rubber or silicone. Specifically, the sealing member 12 may optionally be an O-shaped sealing member, a rectangular sealing member, an irregularly shaped sealing member, or the like. The specific shape of the sealing member 12 may be matched to the shapes of the top of the housing 10 and the two opposing surfaces of the external device. For example, if the top of the housing 10 and the two opposing surfaces of the external device are rectangular, the sealing member 12 may be a rectangular sealing member.

[0164] In this case, the housing 10 of the battery 100 achieves a sealed connection with the external device by the sealing member 12, so that the sealing is reliable and the cost is low.

[0165] As can be seen, the housing 10 of the battery 100 is sealed with the external device by the sealing member 12 and is fixedly connected to the external device via the mounting portion 13a3, and in this case, the top surface h of the housing 10 is in contact with the external device.

[0166] Taking the case where the external device is the body 200 of the vehicle 1000 as an example, the battery 100 is attached to the bottom of the body 200 and is sealed and connected to the body 200 by the sealing member 12 of the sealing zone hc. In this case, the internal region of the sealing member 12 is inside the body 200, and the external region is outside the body 200. Fluids, solid particles, etc. outside the body 200 will not leak into the inside of the body 200. For example, stones or liquids scattered while the vehicle 1000 is running will not impact the inside of the body 200, thereby realizing sealing and structural reliability inside the body 200.

[0167] 7 and 11, in some embodiments, an attachment portion 141b is formed on the top of the housing 10 on the side opposite the receiving cavity s, whereby the battery 100 is attached to an external device via the top of the housing 10, and the attachment portion 141b forms part of the structure of the external device.

[0168] The attachment site 141b is an attachment site configured from a localized region on the top of the housing 10 for attaching a predetermined structure (hereinafter referred to as an attachment part), and this attachment part may be part of the structure of the external device, and the attachment site 141b may be a structure such as an attachment snap or attachment hole having a connecting function. In the case where the external device is the body 200 of the vehicle 1000 as an example, the attachment site 141b is used to attach a structure such as a seat 300 or an operating lever of the vehicle 1000, and the seat 300 or the operating lever is fixedly connected to the attachment site 141b on the top of the housing 10 by a structure such as an attachment snap or attachment hole.

[0169] Specifically, the attachment part attached to attachment portion 141b may be a local structure of the external device, and attachment portion 141b for attaching the local structure of the external device also forms part of the structure of the external device after being connected to the top of housing 10 to the external device. In this case, battery 100 is attached to the external device via the top of housing 10, and after attachment portion 141b on the top of battery 100 forms the local structure of the external device, the attachment part and housing 10 of battery 100 are connected to realize connection with the external device.

[0170] In this way, by integrating part of the structure of the battery 100 and the external device, part of the structure of the battery 100 casing 10 becomes part of the structure of the external device, thereby avoiding the need to provide the battery 100 and the external device separately.

[0171] In other embodiments, the attachment component attached to attachment site 141b may be a structure other than an external device that is attached to attachment site 141b to simultaneously provide a fixed connection to battery 100 and the external device.

[0172] In a specific embodiment, as shown in Figures 14 and 15, for example, if the external device is the body 200 of the vehicle 1000 and the mounting portion 141b is used to mount the seat 300, by configuring the mounting portion 141b at the top of the housing 10 of the battery 100, the mounting portion 141b forms the internal structure of the body 200, forming an integrated arrangement of the battery 100 and the body 200, thereby avoiding the need to separately install the battery 100 and the body 200 and enabling the structure of the vehicle 1000 to be simplified, miniaturized, and made more compact.

[0173] As can be seen, the fixed connection of the housing 10, the body 200, and the seat 300 can ensure that all structures are connected vertically to the top of the housing 10, reducing the installation space in other directions of the housing 10 and the forces applied during installation, reducing the forces applied to the side and bottom structures of the battery 100 housing 10, and improving the stability of the raised vehicle 1000 structure.

[0174] In some embodiments, referring to FIG. 7, the mounting portion 141b includes a mounting hole formed in the top of the housing 10.

[0175] The mounting hole is a through-hole that passes through the mounting portion 141b in the vertical direction, and a fastener is required when mounting the seat 300 or the like to the mounting portion 141b. The mounting hole may be a smooth through-hole (for example, when the fastener is a screw), a through-hole with a thread (for example, when the fastener is a screw), or a through-hole of other shape (for example, a hexagonal hole, a square hole, a constricted hole, etc.). Mounting hole The specific form of the fastener is determined by the specific form of the fastener and the specific setting method, so it will not be described again here.

[0176] The number of mounting holes is the same as the number of fasteners, and each mounting hole is provided with one fastener, which allows the corresponding mounting part to be attached to the mounting hole, thereby fixing the mounting part to the casing 10 of the battery 100 and also realizing a fixed connection between the mounting part and an external device.

[0177] To summarize other embodiments, the attachment portion 141b may include other structures configured on the top of the housing 10, such as snaps, elastic locks, etc., and is not particularly limited thereto.

[0178] 4 to 7 and 11, in some embodiments, the housing 10 includes a main body 11 and an attachment beam 141, the main body 11 surroundingly defines a receiving cavity s, and the top of the main body forms 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 has an attachment portion 141b on the side away from the main body 11.

[0179] The main body 11 may be an integrally molded structure or may be formed by assembling a plurality of parts. The specific arrangement of the main body 11 has been described in detail above, and therefore will not be described again here.

[0180] A top surface h is formed on the side of the top of the housing 10 away from the storage cavity s, and the mounting portion 141b and the top surface h are connected to each other. The mounting beam 141 is a structure with a certain load-bearing capacity provided on the top side of the main body 11, and it distributes the acting force from the mounting parts received on the top of the housing 10. As shown in Figures 15 and 16, if the mounting part is a seat 300, when an operator sits on the seat 300, the pressure is applied, and the pressure is applied first to the mounting beam 141 and then to the top of the housing 10.

[0181] The mounting beam 141 may be provided directly on the surface of the top surface h or in a recessed or protruding portion formed on the top surface h, and one or more load-bearing structures included in the mounting beam 141 form mounting portions 141b on the side away from the top surface h for jointly fixing mounting components, thereby realizing a connection between the mounting components and the top of the housing 10.

[0182] The arrangement method and extension direction of the load-bearing structure are determined according to the size, weight, and specific structure of the mounting part attached to the mounting portion 141b, and are not particularly limited. The mounting beam 141 shares the acting force received by the top of the main body 11, thereby increasing the load-bearing capacity of the housing 10 of the battery 100.

[0183] In some embodiments, the mounting beam 141 and the body 11 may be fixedly connected or integrally formed.

[0184] The mounting beam 141 and the main body 11 can be fixedly connected by fastening, locking with an engaging structure, welding, adhesive, heat welding, etc. Of course, the mounting beam 141 and the main body 11 can also be integrally formed by means of injection molding, die casting, forging, cold pressing, hot pressing, etc.

[0185] If the main body 11 is made of a metal material (e.g., aluminum, iron, stainless steel, etc.), the mounting beam 141 and the main body 11 may be integrally molded by means of die casting, forging, hot pressing, cold pressing, etc. If the main body 11 is made of a plastic material (e.g., PP, PE, ABS, etc.), the mounting beam 141 and the main body 11 may be integrally molded by injection molding. The mounting beam 141 and the main body 11 may also be molded separately and then connected. If the mounting beam 141 and the main body 11 are made of a metal material, the mounting beam 141 and the main body 11 may be welded or glued together. If the mounting beam 141 and the main body 11 are made of a plastic material, the mounting beam 141 and the main body 11 may also be glued together.

[0186] When the mounting beam 141 and the main body 11 are fixedly connected, the molding process of the mounting beam 141 and the main body 11 is simple, and the process cost of the housing 10 can be reduced.

[0187] When the mounting beam 141 and the body 11 are integrally molded, the assembly of the housing 10, external devices and mounting components becomes convenient.

[0188] In other embodiments, the main body 11 is connected to a part other than the mounting beam 141, and the connection method may be integral molding or a fixed connection.

[0189] In some embodiments, referring to Figures 7 and 11, the mounting beam 141 includes at least one protrusion 141a, each of which is located on the top of the main body 11 and protrudes away from the receiving cavity s, and each of the protrusions 141a and the main body 11 jointly form a lightening passage 141a1, and the mounting portion 141b is configured on the side of the protrusion 141a facing away from the main body 11.

[0190] The protrusions 141a are load-bearing structures included in the mounting beam 141 described above, and are provided so as to protrude in a direction away from the accommodating cavity s relative to the plane of the top surface h of the housing 10. The protrusions 141a themselves have a certain height, and are therefore provided so as to protrude from the top surface h of the housing 10. The mounting portions 141b are formed on the sides of all the protrusions 141a that are away from the main body 11. In this case, when a mounting part is attached to the mounting portions 141b, the mounting part does not come into direct contact with the top surface h, but comes into direct contact with the protrusion 141a structure, and therefore the force applied to the top of the housing 10 is distributed by the protrusions 141a, thereby increasing the load-bearing capacity of the top of the housing 10.

[0191] Each protrusion 141a may have a structure surrounded by multiple surfaces and open at one end, and the top surface h1 of the main body 11 covers the open opening of each protrusion 141a and together with it forms a lightening passage 141a1. The lightening passage 141a1 can be formed by hollowing out the inside of the protrusion 141a, drilling holes, digging grooves, or other methods, thereby achieving a lightweight design for the housing 10.

[0192] In one specific embodiment, the interior of each protrusion 141a is provided with a lightening passage 141a1 that penetrates along the extension direction of the protrusion 141a, and the arrangement of the lightening passages 141a1 reduces the weight of each protrusion 141a, thereby further reducing the overall weight and cost of the housing 10. Each lightening passage 141a1 that penetrates can form a hidden passage, and in other embodiments, the hidden passage can be used to perform operations such as dark line placement.

[0193] In some embodiments, referring to FIGS. 6 and 7, the protrusions 141a all extend in the same direction and are spaced apart from one another.

[0194] The direction referred to by "same direction" may specifically be the first direction F1 or the second direction F2 mentioned above, or may be a direction that is flush with and perpendicular to the first direction F1 and the second direction F2, and is not specifically limited.

[0195] "All of the protrusions 141a are spaced apart" means that a predetermined distance is provided between each pair of adjacent protrusions 141a in a direction perpendicular to the direction in which the protrusions 141a extend. This predetermined distance creates a buffer space between each pair of adjacent protrusions 141a, preventing external forces acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the multiple spaced protrusions 141a form a sufficiently wide support area and fixing region to support mounting components over a large area and to accommodate mounting components of different volumes and sizes.

[0196] Since all the protrusions 141a are arranged parallel to one another in the same direction, the buffering space extends in the same direction as the protrusions 141a, which enables buffering at any point in the extension direction of the mounting beam 141 in practical applications.

[0197] The predetermined spacing distance between each two adjacent protrusions 141a may or may not be equal, and as can be understood, in order to ensure uniform support of the mounting parts, the predetermined spacing distance between each two adjacent protrusions 141a is equal.

[0198] In some embodiments, the sides of the protrusions 141a facing away from the main body 11 are all located on the same plane.

[0199] By making all of the protrusions 141a protrude in the same direction and making the protruding height of all of the protrusions 141a the same, the side of all of the protrusions 141a away from the mounting cavity forms a flat surface in a certain direction, for example, a horizontal flat surface, and the mounting parts are placed on the flat surface for mounting, making the mounting process smoother and easier and achieving a strong connection between the mounting parts and the mounting beam 141.

[0200] In a specific embodiment, the protrusions 141a are rectangular pillar-shaped structures, and the same sides of all the protrusions 141a are located on the same plane and jointly define mounting portions 141b for mounting mounting components, so that the mounting components can be smoothly placed on the mounting beam 141.

[0201] In some embodiments, referring to Figures 4, 7 and 11, the housing 10 further includes side impact reinforcement beams 14, which are provided on the top of the main body 11 and extend from the center of the top of the main body 11 toward opposite outer edges of the top of the main body 11.

[0202] The side impact reinforcement beam 14 refers to a beam structure provided on the top of the main body 11 to reinforce the strength of the main body 11. As can be understood, the side impact reinforcement beam 14 is located outside the main body 11. Specifically, the main body 11 and the side impact reinforcement beam 14 may be integrally connected or may be integrally connected by assembly. Integral connection includes, but is not limited to, welding, integral molding, welding, etc. Assembly connection includes, but is not limited to, locking connection, screw connection, etc.

[0203] The side impact reinforcement beams 14 may be provided extending from the center of the top of the main body 11 to opposite outer edges of the top of the main body 11 in the first direction F1, in which case the side impact reinforcement beams 14 can strengthen the side impact prevention capability of the housing 10 in the first direction F1. The side impact reinforcement beams 14 may be provided extending from the center of the top of the main body 11 to opposite outer edges of the top of the main body 11 in the second direction F2, in which case the side impact reinforcement beams 14 can strengthen the side impact prevention capability of the housing 10 in the second direction F2.

[0204] The side impact reinforcing beam 14 may extend from the center of the top of the main body 11 along two directions that are on the same straight line to opposite outer edges of the top of the main body 11, or may extend from the center of the top of the main body 11 along two perpendicular directions to opposite outer edges of the top of the main body 11. When the side impact reinforcing beam 14 extends from the center of the top of the main body 11 along two directions that are on the same straight line to opposite outer edges of the top of the main body 11, the side impact reinforcing beam 14 can be realized by a single straight beam, making the structure simpler.

[0205] The side impact reinforcement beams 14 may extend to the outer edges on both sides, or may extend to the area between the outer edges on both sides and the center, or may extend to an area beyond the outer edges on both sides. In other words, the specific extension length of the side impact reinforcement beams 14 is not limited, and it is sufficient that they extend from the center of the top of the main body 11 to the opposing outer edges on both sides of the top of the main body 11.

[0206] When the battery 100 is applied to a vehicle 1000 and the top of the housing 10 forms the chassis of the vehicle 1000, the vehicle 1000 has weak side impact prevention capabilities in the left and right directions, so the side impact reinforcement beam 14 may be arranged to extend from the center of the top of the main body 11 to the outer edges of both sides of the top of the main body 11 in the left and right directions of the vehicle 1000, thereby strengthening the side impact prevention capabilities of the vehicle 1000 in the left and right directions and improving the safety performance of the vehicle 1000.

[0207] 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 is improved, and further the side impact prevention capability of the vehicle 1000 equipped with the battery 100 made of the housing 10 is improved, thereby contributing to ensuring the safety performance of the battery 100 and the vehicle 1000.

[0208] When the main body 11 includes the frame 11b and the support member 11a, the side impact reinforcement beam 14 is provided at least on the top of the support member 11a. In this case, since the top of the support member 11a forms at least a part of the top of the main body 11, the support member 11a has sufficient space for attaching the side impact reinforcement beam 14.

[0209] In some embodiments, a side impact reinforcement beam 14 extends to connect to the top of the frame 11b.

[0210] In this case, the top of frame 11b also forms part of the top of main body 11, and side impact reinforcement beam 14 may be extended to connect to the top of frame 11b. Frame 11b and support member 11a may be directly connected to each other, or the connection may be reinforced by side impact reinforcement beam 14, thereby increasing the reliability of the connection between frame 11b and support member 11a.

[0211] In some embodiments, the number of side impact reinforcement beams 14 is at least one, and all of the side impact reinforcement beams 14 extend in the same direction and are spaced apart from one another.

[0212] The direction referred to by "same direction" may specifically be the first direction F1 or the second direction F2 mentioned above, or may be a direction that is flush with and perpendicular to the first direction F1 and the second direction F2, and is not specifically limited.

[0213] All of the side impact reinforcement beams 14 extend in the same direction, and each of the side impact reinforcement beams 14 reinforces the side impact prevention capability of the housing 10 in the direction of extension, thereby strengthening the side impact prevention capability of the housing 10 in that direction of extension. As can be understood, the side impact reinforcement beams 14 are provided at intervals along a direction perpendicular to the "same direction," which allows the strength of multiple points of the housing 10 to be strengthened, making the structural strength and side impact prevention capability of the housing 10 more uniform.

[0214] In some embodiments, at least one of the side impact reinforcement beams 14 comprises an attachment beam 141 having an attachment portion 141 b on a side of the attachment beam 141 away from the main body 11 .

[0215] The description of the mounting beam 141 and the mounting portion 141b is given above and will not be repeated here. When one side impact reinforcement beam 14 is included, the side impact reinforcement beam 14 serves as the mounting beam 141. When at least two side impact reinforcement beams 14 are included, one of the beams may serve as the mounting beam 141. Specifically, when at least two side impact reinforcement beams 14 are included, the side impact reinforcement beam 14 closer to the front of the vehicle 1000 is used as the mounting beam 141 to mount the seat 300 (the seat 300 may be the seat 300 in the driver's cab).

[0216] In this case, at least one of the side impact reinforcement beams 14 is used as the attachment beam 141, which not only has the effect of preventing side impacts but also allows other attachment parts to be attached, killing two birds with one stone.

[0217] In some embodiments, the side impact 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 receiving cavity s, and each of which and the main body 11 jointly form a lightening passage 141a1.

[0218] The protrusion 141a of the side impact reinforcing beam 14 may be the same as the protrusion 141a structure mentioned when introducing the mounting beam 141 structure according to the previous embodiment, and for a detailed description, please refer to the above content. The protrusion 141a protrudes in a direction away from the receiving cavity s with respect to the plane on which the top surface h1 of the main body 11 is located, and since the protrusion 141a itself has a certain height, it protrudes from the top surface h1 of the main body 11.

[0219] Each protrusion 141a may have a structure surrounded by multiple surfaces and open at one end, and the top surface h1 of the main body 11 covers the open opening of each protrusion 141a and together with it forms a lightening passage 141a1. The lightening passage 141a1 can be formed by hollowing out the inside of the protrusion 141a, drilling holes, digging grooves, or other methods, thereby achieving a lightweight design for the housing 10.

[0220] In one specific embodiment, the interior of each protrusion 141a is provided with a lightening passage 141a1 that penetrates along the extension direction of the protrusion 141a itself, and the arrangement of the lightening passages 141a1 reduces the weight of each protrusion 141a, thereby further reducing the overall weight and cost of the housing 10. Each lightening passage 141a1 that penetrates through may form a hidden passage, and in other embodiments, the hidden passage may be used to perform operations such as dark line placement.

[0221] In some embodiments, referring to FIG. 7, the protrusions 141a all extend in the same direction and are spaced apart from one another.

[0222] "All of the protrusions 141a are spaced apart" means that a predetermined distance is provided between each pair of adjacent protrusions 141a in a direction perpendicular to the direction in which the protrusions 141a extend. This predetermined distance creates a buffer space between each pair of adjacent protrusions 141a, preventing external forces acting on the mounting beam 141 from being transmitted to the housing 10 and damaging the battery 100. Furthermore, the multiple spaced protrusions 141a form a sufficiently wide support area and fixing region to support mounting components over a large area and to accommodate mounting components of different volumes and sizes.

[0223] Since all the protrusions 141a are arranged parallel to one another in the same direction, the buffering space extends in the same direction as the protrusions 141a, which in actual application allows buffering at any point in the extension direction of the side impact reinforcement beam 14.

[0224] The predetermined spacing 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 predetermined spacing distance between each two adjacent protrusions 141a is equal to ensure uniform support of the mounting parts.

[0225] In some embodiments, the sides of the protrusions 141a facing away from the main body 11 are all located on the same plane.

[0226] One side of all the protrusions 141a is located on the top surface h1 of the main body 11, and all the protrusions protrude in the same direction and have the same protruding height, so that the side of all the protrusions 141a away from the mounting cavity forms a flat surface in a certain direction, for example, a flat surface that forms a horizontal plane, thereby realizing a strong connection between the mounting part and the mounting beam 141.

[0227] In a specific embodiment, the protrusions 141a may be rectangular pillar-shaped structures, and the same sides of all the protrusions 141a may be located on the same plane and jointly define mounting portions 141b for mounting the mounting components so that the mounting components can be smoothly placed on the mounting beam 141.

[0228] In some embodiments, referring to FIG. 10, the housing 10 forms a battery cavity s1 and a high-voltage cavity s2 that are independently provided, and the battery cavity s1 is used to accommodate the battery cell 20, and the high-voltage cavity s2 is used to accommodate the high-voltage box.

[0229] The high-voltage box is an important safety barrier for the 100 batteries. It is equipped with a high-voltage control system, which is mainly used to turn on or off the high-voltage circuit according to the electrical control requirements of the entire vehicle, provide current and leakage detection terminals, realize controllable current cut-off when the external current of the 100 batteries is too large, turn off the high-voltage circuit when a short circuit occurs in the external circuit of the 100 batteries, prevent the 100 batteries from catching fire, and conveniently cut off the high-voltage circuit when maintaining the 100 batteries.

[0230] The battery cavity s1 and the high-pressure cavity s2 being provided independently of each other means that the battery cavity s1 and the high-pressure cavity s2 are sealed from each other. To achieve this independent arrangement of the battery cavity s1 and the high-pressure cavity s2, the battery cavity s1 and the high-pressure cavity s2 are formed separately from two independent components. For example, a first member and a second member are provided independently inside the housing 10, with the first member forming the battery cavity s1 and the second member forming the high-pressure cavity s2. Alternatively, a partition is provided inside the housing 10 to separate the storage cavities s formed inside the housing 10 and form the independent battery cavities s1 and high-pressure cavities s2. Alternatively, all storage cavities s formed inside the housing 10 are battery cavities s1, and a single high-pressure tank 15 is provided outside the housing 10 to form the high-pressure cavity s2, thereby achieving the independence of the battery cavity s1 and the high-pressure cavity s2.

[0231] The battery cavity s1 is used to accommodate the battery cell 20, and the high-pressure cavity s2 is used to accommodate the high-pressure box. When the battery cavity s1 and the high-pressure cavity s2 are installed independently, the battery cell 20 in the battery cavity s1 will not thermally fail and leak high-temperature gas will not enter the high-pressure box, thereby preventing thermal damage to the high-pressure control system in the high-pressure box. This ensures the normal control function of the high-pressure control system and improves the safety performance of the battery 100.

[0232] In some embodiments, referring to Figures 11 to 13, the housing 10 further includes a high-pressure tank 15, in which a battery cavity s1 is formed within the main body 11, and the high-pressure tank 15 is installed outside the main body 11 and surrounds or co-encloses with the main body 11 to form a high-pressure cavity s2.

[0233] The high-pressure tank 15 may have a case 22 structure, the interior of which is hollow and forms the high-pressure tank 15 for accommodating the high-pressure box. The high-pressure tank 15 is provided outside the main body 11, and the battery cavity s1 is formed by the main body 11 (in this case, the battery cavity s1 corresponds to the accommodating cavity s), thus realizing an independent arrangement of the high-pressure cavity s2 and the battery cavity s1.

[0234] When the high-pressure tank 15 and the main body 11 jointly form the high-pressure cavity s2, the high-pressure tank 15 has one opening and is attached to the main body 11 through the opening. When the high-pressure tank 15 surrounds itself to form the high-pressure cavity s2, only an attachment relationship exists between the high-pressure tank 15 and the main body 11.

[0235] In this case, a high-pressure cavity s2 is defined by a high-pressure tank 15 provided outside the main body 11, and the accommodating cavity s formed by the main body 11 can accommodate a battery cell 20 as a battery cavity s1 for accommodating a battery, thereby increasing the electrical capacity of the battery 100.

[0236] In some embodiments, referring to FIGS. 11 and 12, the high-pressure tank 15 is protruded from the top of the main body 11.

[0237] The high-pressure tank 15 protrudes from the top of the main body 11, that is, the high-pressure tank 15 is located outside the main body 11 and is provided on the top surface h1 of the main body 11. When the battery 100 housing 10 is used as the chassis of the vehicle 1000, since the high-pressure tank 15 is located on the top of the main body 11, it is not exposed to the outside of the vehicle 1000 and can be protected from external impacts (for example, stones flying while the vehicle 1000 is traveling), making the high-pressure tank 15 safer.

[0238] As can be understood, when the main body 11 includes the frame 11b and the support member 11a, the support member 11a constitutes at least a part of the top of the main body 11, and the high-pressure tank 15 is provided on the top of the support member 11a and surrounds or surrounds together with the support member 11a to form the high-pressure cavity s2. In this case, since the support member 11a constitutes most of the area of ​​the top of the main body 11, by providing the high-pressure tank 15 on the top of the support member 11a, the installation space for the high-pressure tank 15 becomes larger and the installation becomes more stable.

[0239] Of course, if the top of the frame 11b is also configured as part of the top of the main body 11, the high-pressure tank 15 may be provided at the top of the frame 11b, and specifically, may be set according to the mounting method between the frame 11b and the support member 11a.

[0240] In some embodiments, referring to FIGS. 11-13, the high-pressure tank 15 is provided near the top outer edge of the main body 11.

[0241] The top outer edge of the main body 11 includes an outer edge installed on the front side of the top of the main body 11 toward the vehicle 1000, an outer edge installed on the rear side of the top of the main body 11 toward the vehicle 1000, an outer edge installed on the left side of the top of the main body 11 toward the vehicle 1000, and an outer edge installed on the right side of the top of the main body 11 toward the vehicle 1000.

[0242] In one application example, the high-pressure tank 15 is provided on the top of the main body 11 near the outer edge of one side of the rear of the vehicle 1000, i.e., the high-pressure tank 15 is provided near the rear of the vehicle 1000.In this case, the high-pressure tank 15 may be provided corresponding to the passenger space behind the driving space of the vehicle 1000, and in particular, may be provided corresponding to under the seat 300 in the passenger space, so as not to occupy the activity space of the vehicle 1000.

[0243] In some embodiments, referring to Figures 4, 6, and 11 to 13, the high-pressure tank 15 and the side impact reinforcement beam 14 are arranged sequentially in a first direction F1, and the side impact reinforcement beam 14 extends along a second direction F2 perpendicular to the first direction F1.

[0244] If the housing 10 includes a side impact reinforcement beam 14, the high pressure tank 15 may be mounted on top of the body 11 together with the side impact reinforcement beam 14.

[0245] The high-pressure tank 15 and the side impact reinforcement beams 14 are arranged sequentially in the first direction F1, which means that the high-pressure tank 15 is located on one side of all of the side impact reinforcement beams 14 in the first direction F1. Moreover, the side impact reinforcement beams 14 extend in a second direction F2 perpendicular to the first direction F1 and do not interfere with the high-pressure tank 15. This makes the structural layout of the high-pressure tank 15 and the side impact reinforcement beams 14 rational and increases the utilization rate of the space at the top of the main body 11.

[0246] In a specific embodiment, referring to Figure 4, the high-pressure tank 15 includes a tank lid 15a and a tank box 15b. The tank box 15b is provided on the top of the main body 11 and forms a high-pressure cavity s2 that is open on the side away from the main body 11. The tank lid 15a detachably covers the open side of the high-pressure cavity s2.

[0247] The tank box 15b and the main body 11 may be connected by welding, bonding, adhesive, fastening, etc. Optionally, the tank box 15b may be made of plastic. The tank lid 15a and the tank box 15b may be detachably connected by a fastener or by a locking connection, and the specific form is not limited.

[0248] In this case, the high-pressure cavity s2 is formed by the tank box 15b, the high-pressure cavity s2 is sealed by the tank lid 15a, and the tank lid 15a and the tank box 15b are detachably connected, which makes the installation and maintenance of the high-pressure box convenient.

[0249] Fig. 17 is a schematic diagram of a local structure of a battery 100 according to 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 top view of the structure shown in Fig. 17.

[0250] In some embodiments, referring to Figures 17 to 21, the housing 10 further includes a central passage beam 16, which extends along a first direction F1 and is provided at the top of the main body 11, and is provided at equal distances from both outer edges of the top of the main body 11 in a second direction F2 perpendicular to the first direction F1, and the central passage beam 16 has a wiring passage 16a for inserting a wire harness.

[0251] In a traditional vehicle 1000, a central aisle beam 16 structure is usually provided on the chassis of the body 200 of the vehicle 1000. The central aisle beam 16 is a beam structure extending from the front chassis to the rear chassis on the body 200 of the vehicle 1000, and is a main structural member that ensures the collision transmission path of the body 200 and the bottom plate rigidity of the body 200. The central aisle beam 16 is provided in the central region of the chassis of the vehicle 1000 and extends from the front chassis to the rear chassis along the longitudinal direction of the vehicle 1000.

[0252] In this embodiment, the central aisle beam 16 of the vehicle 1000 is directly integrated into the top of the main body 11 of the housing 10. Specifically, since the central aisle beam 16 is provided in the central region of the top of the main body 11, it extends along a first direction F1 (corresponding to the longitudinal direction of the vehicle body 200) and is provided at equal distances from both outer edges of the top of the main body 11 in a second direction F2 (corresponding to the lateral direction of the vehicle body 200).

[0253] Usually, the central passage beam 16 is designed to have a hollow structure in order to reduce the weight of the vehicle body 200. In this embodiment, the hollow structure provided inside the central passage beam 16 is used to form a wiring passage 16a for installing a wire harness, which not only reduces the weight but also allows for the placement of the wire harness, improving the degree of freedom and safety of the wire harness placement.

[0254] The central passageway beam 16 may be a sheet metal member integrally formed by stamping, die casting, or the like, or may be a beam structure formed by welding, fusing, or fastening multiple sheet metal plates together, as long as it has a wiring passage 16a for wiring. The wiring passage 16a may be located inside the central passageway beam 16 (e.g., a hole passage inside the central passageway beam 16) or outside the central passageway beam 16 (e.g., a recessed groove passage recessed on the outside of the central passageway beam 16). The central passageway beam 16 may form the wiring passage 16a together with the main body 11, or it may form the wiring passage 16a by itself. The central passageway beam 16 and the main body 11 may be connected to each other by means of welding, fusing, fastening, or the like, to form a single unit.

[0255] The wiring passage 16a of the central passage beam 16 may extend along the extending direction of the central passage beam 16 (i.e., the first direction F1), or may be designed in any other required form, and is not specifically limited as long as it realizes wiring. In order to realize sorting wiring of various types of wire harnesses and to facilitate installation and maintenance, the central passage beam 16 may have a plurality of independent wiring passages 16a.

[0256] In this case, the top of the housing 10 is configured as the chassis of the body 200 of the vehicle 1000 (the chassis is the floor of the body 200), and there is no need to additionally arrange the central passage beam 16, further improving the assembly efficiency of the body 200. At the same time, the hollow structure formed inside the central passage beam 16 is used to form a wiring passage 16a for drilling the wire harness, which not only reduces the weight but also enables the arrangement of the wire harness and improves the degree of freedom in arranging the wire harness.

[0257] In some embodiments, referring to FIG. 20, the central passage beam 16 includes a beam seat 161, which is provided at the top of the main body 11 and forms a wire routing groove 16a1 as the wiring passage 16a, and the wire routing groove 16a1 is recessed toward the storage cavity s.

[0258] The beam seat 161 may be directly mounted on the main body 11 and fixed to the main body 11 by means of welding, bonding, fastening, etc. The beam seat 161 forms a wire-passing groove 16a1, which is recessed toward the receiving cavity s, i.e., the wire-passing groove 16a1 has a groove opening away from the receiving cavity s, which makes it easy to drill the wire harness.

[0259] The wire passing groove 16a1 may be a continuous groove structure recessed into the surface of the beam seat 161 away from the accommodating cavity s, or may be a wire passing portion having recessed grooves recessed toward multiple accommodating cavities formed on the surface of the beam seat 161 away from the accommodating cavity s, and each wire passing portion is arranged at intervals along a predetermined direction, and the recessed grooves of all the wire passing portions collectively form the wire passing groove 16a1 of the beam seat 161.

[0260] In this case, the beam seat 161 forms a wire-passing groove 16a1 recessed toward the receiving cavity s, which makes it easier to install the wire harness.

[0261] In some embodiments, referring to FIG. 20, there are a plurality of wire passing grooves 16a1, all of which extend in the same direction and are spaced apart from one another.

[0262] A plurality of wire routing grooves 16a1 may be provided, and the plurality of wire routing grooves 16a1 may extend in the same direction (for example, the first direction F1) and may be spaced apart. Each wire routing groove 16a1 is used for routing one type of wire harness (wire harnesses are classified according to the connection target of the wire harness, for example, wire harnesses connected to air conditioners, wire harnesses connected to lights, wire harnesses connected to power drive systems, etc.).

[0263] This allows different types of wire harnesses to be installed independently, making the installation and maintenance of the wire harnesses more convenient.

[0264] In some embodiments, the wire slot 16a1 is configured to provide a locking connection to the wire harness that passes through it.

[0265] To achieve the locking connection of the wire passing groove 16a1 to the wire harness, the groove opening size of the wire passing groove 16a1 may correspond to the diameter of the wire harness through which it is drilled, or the two may be oversized to achieve the locking connection. Specifically, a locking connecting member may be provided at the opening of the wire passing groove 16a1, with one end of the locking connecting member rotatably connected to one side of the opening of the wire passing groove 16a1 and the other end detachably connected to the other side of the opening of the wire passing groove 16a1. After the wire harness is placed in the wire passing groove 16a1, the locking connecting member is locked into the opening of the wire passing groove 16a1 to lock the wire harness in the wire passing groove 16a1.

[0266] This makes it possible to avoid noise caused by rattle of the wire harness, and also to avoid the problem of the wire harness coming out of the wire-passing groove 16a1 and being damaged.

[0267] In some embodiments, referring to FIG. 20, the central passage beam 16 further includes a beam cover 162, which removably covers the open side of the wire-passing groove 16a1.

[0268] The opening side of the wire-passing groove 16a1 is the side where the groove opening of the wire-passing groove 16a1 is located. The beam cover 162 detachably covering the opening side of the wire-passing groove 16a1 means that the beam cover 162 and the beam seat 161 are detachably connected. Specifically, the beam cover 162 and the beam seat 161 are detachably and lockingly connected, or the beam cover 162 and the beam seat 161 are detachably connected via a fastener (e.g., a bolt). The manner in which the beam cover 162 and the beam seat 161 are detachably connected can be any conventional manner in the art, and will not be limited or described in detail herein.

[0269] In this case, by covering the groove opening of the wire-passing groove 16a1 with the beam cover 162, it is possible to prevent external dust and moisture from entering the wire-passing groove 16a1 and corroding the wire harness, and also to protect the wire harness from being pressed or destroyed by external forces, thereby improving the safety of the battery 100.

[0270] In some embodiments, the high pressure cavity s2 and the wiring passage 16a are in communication with each other.

[0271] As can be appreciated, typically a wire harness is pulled out from the high voltage box in the high voltage cavity s2 and then supplies power to an electrical device, and therefore the wire harness passes through the high voltage cavity s2 and the routing passage 16a.

[0272] The communication between the high-pressure cavity s2 and the wiring passage 16a means that the wire harness coming out of the high-pressure cavity s2 can enter the wiring passage 16a. Specifically, the high-pressure cavity s2 may have a wiring opening facing the entrance of the wiring passage 16a. In this case, there is no obstacle between the wiring opening and the entrance of the wiring passage 16a, and the wire harness coming out through the wiring opening can be guided straight to the entrance of the wiring passage 16a without being bent. Specifically, the high-pressure cavity s2 has a wiring port, and the wiring port and the entrance of the wiring passage 16a are not opposed to each other but are spatially connected. In this case, an obstacle (the obstacle may be formed by the central passage beam 16 or may be another structure) exists between the wiring port and the entrance of the wiring passage 16a, and the wire harness coming out through the wiring port may be folded back to bypass the obstacle and then enter the wiring passage 16a through the entrance of the wiring passage 16a. stomach.

[0273] In this case, the high-pressure cavity s2 and the wiring passage 16a are in communication with each other, and the wiring harness coming out of the high-pressure cavity s2 is routed through the wiring passage 16a.

[0274] In some embodiments, referring to Figures 17 and 21, the central passage beam 16 and the high-pressure tank 15 are disposed adjacent to each other along the first direction F1.

[0275] The central aisle beam 16 typically extends correspondingly from the front chassis of the vehicle body 200 to the rear chassis of the vehicle body 200, and the high-pressure tank 15 is located on one side of the central aisle beam 16 in the first direction F1, and the high-pressure tank 15 may be provided in front of or behind the central aisle beam 16. Specifically, the high-pressure tank 15 is provided behind the central aisle beam 16, and corresponds to the position of the rear chassis of the vehicle body 200, which position is used to install seats 300 in the passenger cabin of the vehicle 1000, so the high-pressure tank 15 can be hidden in the space below the seats 300, thereby further improving the space utilization rate of the passenger cabin of the vehicle 1000.

[0276] In some embodiments, referring to FIG. 11, a first region ha and a second region hb are formed on the top surface h of the housing 10, the second region hb surrounds the first region ha, a plurality of mounting portions 13a3 are formed in the second region hb, and the battery 100 is attached to an external device via the mounting portions 13a3.

[0277] The first region ha and the second region hb may be formed by dividing other structures, for example, by providing a sealing member 12 on the top of the housing 10 and dividing the top surface h of the housing 10 into a second region hb located on the outer periphery of the sealing member 12 and a first region ha located on the inner periphery of the sealing member 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.

[0278] The first region ha and the second region hb may be formed by automatically dividing them into sections on the top surface h. In this case, there may be no other structural spacing between the first region ha and the second region hb, and the first region ha and the second region hb may also be connected to each other when the battery 100 is attached to an external device via the mounting portion 13a3.

[0279] Moreover, 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 uneven surfaces, and their specific configurations are not limited.

[0280] In a specific embodiment, for example, when the external device is the body 200 of the vehicle 1000 and the mounting portion 13a3 is configured in the second region hb and the housing 10 is connected to the body 200 via a more outer region of the top, the housing 10 receives only the vertical acting force of the body 200, thereby reducing the force transmission path and advantageously improving the rigidity and lateral pressing ability of the entire vehicle.

[0281] As can be understood, the top surface h of the housing 10 may include not only the first region ha and the second region hb but also other regions, which may be located between the first region ha and the second region hb, surrounding the first region ha and the second region hb, or inside the second region hb, and is not particularly limited in this application.

[0282] In some embodiments, referring to FIGS. 13 and 14, the distance L2 between the geometric centers of the orthogonal projections of the second regions hb of each two adjacent mounting portions 13a3 is 80 mm to 500 mm.

[0283] Orthogonal projection is a projection perpendicular to the projection plane of the parallel projection line, i.e., a projection of the mounting portion 13a3 onto the second region hb along a direction perpendicular to the second region hb. When the mounting portions 13a3 are connected to an external device, each mounting portion 13a3 has one mounting force receiving point, and the geometric center of the orthogonal projection of the second region hb of each mounting portion 13a3 is the mounting force receiving point. The distance between each two adjacent mounting force receiving points (i.e., distance L2) is controlled to 80 to 500 mm, thereby ensuring that the battery 100 is mounted uniformly on the external device and increasing the connection strength between the battery 100 and the external device.

[0284] In a specific embodiment, when the external device is the body 200 of the vehicle 1000, the mounting portion 13a3 is configured to include a plurality of mounting holes k1, so that the housing 10 of the battery 100 is connected to the body 200 via the plurality of mounting holes k1. Moreover, by setting the distance L2 between the geometric centers of adjacent mounting holes k1 within a predetermined range, it is ensured that the arrangement distance between the mounting holes k1 (i.e., the distance L2) is controllable, and by controlling the arrangement distance between the mounting holes k1, it is ensured that the plurality of mounting positions on the housing 10 are essentially uniformly distributed, so that the body 200 receives a uniform force and further improves the connection rigidity at each location between the body 200 and the housing 10.

[0285] As can be understood, in some other embodiments, when it is necessary to realize personalized settings, for example, when it is necessary to arrange the mounting portion 13a3 so as to be divided into high-density mounting zones and low-density mounting zones, in order to meet the needs of personalized settings of local high-density mounting and local low-density mounting, the distance between each mounting hole k1 in the high-density mounting zone (i.e., distance L2) is arranged as close as possible to 80 mm, and the distance between each mounting hole k1 in the low-density mounting zone (i.e., distance L2) is arranged as close as possible to 500 mm.

[0286] In some embodiments, referring to FIGS. 13 and 14, the distance L2 between the geometric centers of the orthogonal projections of the second regions hb of each two adjacent mounting portions 13a3 is 80 mm to 300 mm.

[0287] By setting the distance L2 in the range of 80 mm to 300 mm, it is possible to ensure a uniform connection between the battery 100 and the external device, and also to ensure the strength of the connection between the battery 100 and the external device.

[0288] In some embodiments, referring to Figures 13 to 14, the top surface h of the housing 10 further forms a sealing zone hc, which is located between the first area ha and the second area hb and surrounds the first area ha, and the sealing zone hc is used to attach the sealing member 12, which is used to contact an external device.

[0289] The sealing zone 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 so that they are non-communicating with each other. It is preferable that the sealing zone hc is not too large in area, and its main role is to attach the sealing member 12 and separate the first region ha and the second region hb from each other. By arranging this to match the size, volume, and shape of the sealing member 12 as closely as possible, the entire sealing member 12 is assembled into the sealing zone hc.

[0290] As can be seen, the sealing member 12 has different states within the sealing zone hc: when the sealing member 12 contacts an external device and the housing 10 is fixedly connected to the external device, the sealing member 12 is in a compressed state and undergoes some deformation to ensure sealing; when the battery 100 is separated from the external device, the sealing member 12 returns to its original state.

[0291] In a specific embodiment, for example, the external device may be the body 200 of the vehicle 1000, and the battery 100 may be attached to the bottom of the body 200 and sealed to the body 200 via a sealing member 12 on the sealing zone hc. In this case, the first region ha forms the closed interior of the body 200, and the second region hb is the exterior of the body 200. Fluids, solid particles, etc. outside the body 200 do not leak into the interior of the body 200. For example, stones or liquids scattered while the vehicle 1000 is running do not impact the interior of the body 200, thereby realizing the sealing property and structural reliability of the interior of the body 200.

[0292] As can be understood, when the housing 10 includes the sealing member 12, the sealing member 12 is attached to the sealing zone hc to seal and separate the first region ha and the second region hb. The specific arrangement of the sealing member 12 has been described in detail above, so it will not be described again here. The top surface h of the housing 10 may include other regions in addition to the first region ha, the sealing zone hc, and the second region hb, and the other regions may be provided inside the first region ha or outside the second region hb, and is not particularly limited in the present application.

[0293] 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 onto the second region hb and the outer edge of the sealing zone hc is 30 mm to 200 mm.

[0294] When the mounting portion 13a3 is projected onto the second region hb in a direction perpendicular to the second region hb and the mounting portion 13a3 is connected to an external device, each mounting portion 13a3 has one mounting force receiving point, and the geometric center of the orthogonal projection of the second region hb of each mounting portion 13a3 is the mounting force receiving point of each mounting portion 13a3. The shortest distance L1 between the geometric center of the orthogonal projection of the second region hb of each mounting portion 13a3 and the outer edge of the sealing zone hc is the shortest distance between the mounting force receiving point of each mounting portion 13a3 and the outer edge of the sealing zone hc.

[0295] The outer edge of the sealing zone hc is the boundary line shared by the sealing zone hc and the second region hb, and of course the sealing zone hc also has an inner edge, which is the boundary line shared by the sealing zone hc and the first region ha. When the sealing member 12 is assembled, both edges of the sealing member 12 overlap the inner and outer edges of the sealing zone hc so that the sealing member 12 completely covers the sealing zone hc.

[0296] The shortest distance L1 between the geometric center of the orthogonal projection of the second region hb of the mounting portion 13a3 and the outer edge of the sealing zone hc means the length of the perpendicular line obtained by drawing a perpendicular line from the geometric center of each mounting portion 13a3 to the outer edge of the sealing zone hc, and ensures that the distance between the sealing member 12 and the mounting portion 13a3 is within the specified range.

[0297] In one specific embodiment, for example, the external device is the body 200 of the vehicle 1000, and by controlling the shortest distance (i.e., distance L1) between the mounting force receiving point of the mounting portion 13a3 and the outer edge of the sealing zone hc to 30 mm to 200 mm, the mounting force receiving point of the mounting portion 13a3 is prevented from being too far away from the sealing member 12, ensuring the sealing effect of the sealing member 12 inside the body 200, while reducing the mounting torque caused by mounting each mounting portion 13a3 to the body 200, effectively shortening the mounting arm, and ensuring the connection rigidity between the battery 100 and the body 200.

[0298] In some embodiments, referring to FIGS. 13 and 14, the shortest distance L1 between the geometric center of the orthogonal projection of the second region hb of the mounting portion 13a3 and the outer edge of the sealing zone hc is 50 mm to 100 mm.

[0299] If the distance is 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 sealing member 12, ensuring the sealing effect of the sealing member 12 between the first region ha and the second region hb, and also ensuring the strength of the connection between the battery 100 and the external device.

[0300] In some embodiments, the sealing zone hc and the second region hb are coplanar.

[0301] Being located on the same plane is also referred to as being flush, and means that the sealing zone hc and the second region hb occupy the same plane in three-dimensional space, in which case the sealing zone hc and the second region hb are configured as flat surfaces without any angle to each other.

[0302] In a specific embodiment, the external device is the body 200 of the vehicle 1000, and when the housing 10 is assembled to the bottom of the body 200 through the top, the sealing zone hc and the second region hb have the same height in the vertical direction, the sealing zone hc is used to arrange the sealing member 12 to perform the sealing function, and the second region hb is configured with a mounting member to perform the mounting function. In this case, the mounting force receiving point of each mounting portion 13a3 and the sealing zone hc are on the same plane and at the same height, and both the mounting force receiving point and the sealing member 12 are subjected to force only in the vertical direction, thereby reducing the force received by the lateral structure of the housing 10 and the body 200 and improving the rigidity of the vehicle 1000.

[0303] In some embodiments, referring to FIG. 11, the first region ha, the second region hb and the sealing zone hc are coplanar.

[0304] In this case, the same plane on which the first region ha, the second region hb, and the sealing zone hc exist is in contact with the external device, and the contact area between the top surface h of the housing 10 and the external device is relatively large, which is advantageous in increasing the connection reliability between the housing 10 and the external device, and the top structure of the housing 10 becomes flat, improving the aesthetic appearance.

[0305] When the external device is the body 200 of the vehicle 1000, the internal region of the body 200 forming the top surface h of the housing 10, the external region of the body 200 and the sealing zone hc are all arranged on the same plane, thereby ensuring that both the internal and external regions of the body 200 of the housing 10 are subjected to vertical forces only, and further reducing the forces applied to the lateral structures of the vehicle 1000.

[0306] In some embodiments, referring to FIG. 14, when the mounting portion 13a3 includes at least one mounting hole k1, the mounting holes k1 all pass through the second region hb.

[0307] Regarding the introduction of the mounting hole k1, please refer to the above content and will not be repeated here. If the mounting hole k1 is provided through the second region hb, when the connecting member connects the housing 10 to an external device, it can be connected to the top of the housing 10 through the second region hb near the outer periphery of the top of the housing 10, thereby increasing the connection strength between the housing 10 and the external device.

[0308] In some embodiments, referring to FIG. 14, there is a predetermined distance between the outer edge of the sealing zone hc close to the second region hb and the circumferential sidewall n of the body 11.

[0309] Circumferential side wall of the main body 11 n For the introduction, please refer to the above content and will not be repeated here. The outer edge of the sealing zone hc adjacent to the second region hb is not vertically coplanar with the plane on which the circumferential side wall n of the main body 11 exists, and there is a predetermined distance between the outer edge of the sealing zone hc and the outer edge of the top surface h1 of the main body 11.

[0310] When the sealing member 12 is assembled and not deformed, the edges on both sides of the sealing member 12 overlap with the edges on both sides of the sealing zone hc, and when the sealing member 12 is sealed and connected to an external device, the sealing member 12 deforms and both sides overflow the sealing zone hc, with one side extending beyond the sealing zone hc into the first region ha and the other side extending beyond the sealing zone hc into the second region hb.

[0311] The outer edge of the sealing zone hc near the second region hb and the body 11 Zhou By providing a predetermined distance between the side wall and the sealing member 12, sufficient deformation space can be secured for the sealing member 12 to deform, and it is possible to prevent the sealing member 12 from spilling over the top surface h1 of the main body 11 into other areas of the top of the housing 10 and interfering with the structure of other areas.

[0312] 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 of the housing 10.

[0313] The top surface h1 of the main body 11 refers to the top surface of the main body 11, facing away from the receiving cavity s. When the housing 10 includes both the main body 11 and the side beams 13 according to the above embodiment, the top surface h of the housing 10 can be jointly defined by the top surface h1 of the main body 11 and the top surface h2 of the side beams 13. The top surfaces h1 of the main body 11 and h2 of the side beams 13 can be coplanar. In this case, the contact area between the top surface h of the housing 10 and an external device is relatively large, which is beneficial for improving the connection reliability between the housing 10 and the external device. At the same time, the top structure of the housing 10 is flat, improving its aesthetic appearance. Of course, the top surfaces h1 of the main body 11 and h2 of the side beams 13 do not have to be coplanar.

[0314] In other embodiments, the housing 10 may further 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 jointly defined by the top surface h1 of the main body 11, the top surface h2 of the side beams 13, and the top surfaces of the other structures.

[0315] As can be understood, the first region ha and the sealing zone hc are located on the top surface h1 of the main body 11, and in addition to the first region ha and the sealing zone hc, the top surface h1 of the main body 11 may further include other regions, which are not specifically limited here.

[0316] In some embodiments, referring 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.

[0317] The top surface h1 of the main body 11 is divided into a first region ha, a sealing zone hc provided around the outside of the first region ha, and a second region hb provided around the outside of the sealing zone hc, and when the sealing member 12 in the sealing zone hc is compressed and deformed, one side edge of the sealing member 12 extends into the second region hb of the top surface h1 of the main body 11.

[0318] As can be understood, the second region hb of the top surface h1 of the main body 11 is a predetermined distance between the outer edge of the sealing zone hc close to the second region hb and the circumferential side wall n of the main body 11, which ensures sufficient deformation space for the deformation of the sealing member 12 and prevents the sealing member 12 from overflowing beyond the top surface h1 of the main body 11 onto the side beam 13 when it deforms.

[0319] 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.

[0320] The mounting hole k1 is described above and will not be described again here. If the mounting hole k1 is located in the second region hb defined by the top surface h2, it will have the same beneficial effect as if the mounting portion 13a3 were located on the top of the side beam 13, and will not be described again here.

[0321] When the housing 10 includes the main body 11 and the side beams 13 according to the above embodiment, the top surface h of the housing 10 may be jointly defined by the top surface h1 of the main body 11 and the top surface h2 of the side beams 13. Zhou By providing a predetermined distance between the sealing member 12 and the side wall in the direction of the sealing member 12, sufficient deformation space can be secured for the sealing member 12 to deform, and it is possible to prevent the sealing member 12 from overflowing onto the top surface h2 of the side beam 13 when it deforms, and interfering with the mounting of the mounting portion 13a3 on the side beam 13.

[0322] In some embodiments, referring to FIG. 14, the mounting portions 13a3 are provided on the first sub-beam 13a1 and / or the second sub-beam 13a2, and the distance L2 between the geometric centers of the orthogonal projections of each two adjacent mounting portions 13a3 onto the second region hb in the first direction F1 and / or the second direction F2 is between 80 mm and 500 mm.

[0323] The first sub-beam 13a1 and the second sub-beam 13a2 are described above and will not be described again here. The two first sub-beams 13a1 extend along a first direction F1, and the two second sub-beams 13a2 extend along a second direction F2. By disposing the mounting portions 13a3 on the first sub-beams 13a1 and / or the second sub-beams 13a2, respectively, the mounting portions 13a3 extend along the first direction F1 and / or the second direction F2, thereby achieving uniform mounting and fixing with an external device in multiple directions and further improving the connection between the external device and the housing 10.

[0324] Furthermore, by setting the distance between the geometric centers of the orthogonal projections of the second regions hb of each two adjacent mounting portions 13a3 and the distance between the geometric centers of adjacent mounting holes k1 within a specified range in a limited, predetermined direction, the specified distance between the mounting holes k1 can be controlled along the extension direction of the first sub-beam 13a1 and the extension direction of the second sub-beam 13a2, ensuring that the force applied to the vehicle body 200 is uniform.

[0325] As can be appreciated, if the housing 10 includes a central passageway beam 16, the central passageway beam 16 may be provided in a central region of the body 11 by locating the central passageway beam 16 in the first region ha.

[0326] In one embodiment, the housing 10 includes the main body 11 and the high-pressure tank 15, the battery cavity s1 is formed within the main body 11, the high-pressure tank 15 is provided on the top of the main body 11 and is located in the first region ha, and the high-pressure tank 15 forms the high-pressure cavity s2 by itself or together with the main body 11. Since the first region ha forms most of the area of ​​the top of the main body 11, placing the high-pressure tank 15 in the first region ha can improve the space utilization rate of the first region ha.

[0327] 3 and 4, the present application also provides a battery 100 including the housing 10 according to any of the above embodiments and a battery cell 20, where the battery cell 20 is housed in a housing cavity s. Since the battery 100 includes the housing 10, it has all the beneficial effects of the housing 10, which will not be described again here.

[0328] In some embodiments, the battery 100 further includes a high-voltage box (not shown), and the housing 10 forms a battery cavity s1 and a high-voltage cavity s2 that are provided independently of each other, the battery cavity s1 being used to accommodate the battery cell 20, and the high-voltage cavity s2 being used to accommodate the high-voltage box.

[0329] The high-voltage box is an important safety barrier for the 100 batteries, and is equipped with a high-voltage control system. It is mainly used to turn on or off the high-voltage circuit according to the electrical control requirements of the entire vehicle, provide current and leakage detection terminals, realize controllable current cut-off when the external current of the 100 batteries is too large, turn off the high-voltage circuit when a short circuit occurs in the external circuit of the 100 batteries, prevent the 100 batteries from catching fire, and conveniently cut off the high-voltage circuit when maintaining the 100 batteries.

[0330] In this case, the high-voltage box connects and collects the current of all the battery cells 20 and supplies safe electrical energy to the outside, thereby realizing safe power supply to the outside of the battery 100. For the specific structure of the high-voltage box, reference can be made to conventional settings in this field, and this application does not relate to specific improvements to the high-voltage box.

[0331] In some embodiments, referring to Figures 10 and 20, the housing 10 includes a main body 11, which surrounds and forms a storage cavity s, and the main body 11 includes a support member 11a located on the top of the housing 10 and defining the storage cavity s, and the battery cell 20 is provided on the support member 11a.

[0332] The explanations regarding the main body 11, the top of the housing 10, and the support member 11a are given above and will not be repeated here. In this case, the support member 11a is a component capable of bearing the weight of the battery cells 20, and may be a carrier plate, carrier block, carrier sheet, carrier frame, etc., but is not particularly limited thereto.

[0333] Specifically, the battery cells 20 are provided below the support member 11a and, together with the support member 11a, bear the force applied to the top of the battery 100 housing 10, thereby improving the rigidity of the top of the battery 100 housing 10.

[0334] In some embodiments, referring to Figures 10 and 20, the battery cells 20 are suspended from a support member 11a.

[0335] The battery cells 20 being suspended from the support member 11a means that the battery cells 20 are provided vertically below the support member 11a and that the weight of the battery cells 20 is borne by the support member 11a. Forms of suspending the battery cells 20 from the support member 11a include directly bonding the battery cells 20 to the underside of the support member 11a, connecting the battery cells 20 to the support member 11a via fasteners and being located below the support member 11a, and suspending the battery cells 20 from the support member 11a via hooks or the like and being located below the support member 11a.

[0336] In this case, because the battery cells 20 are suspended below the support member 11a and the bottom cover 11c is located at the bottom of the housing 10, there is no need to remove the support member 11a when performing maintenance on the inside of the battery 100; simply removing the bottom cover 11c exposes the battery cells 20, making maintenance of the battery 100 more convenient. At the same time, when performing maintenance on the battery 100, the battery cells 20 can be attached to and detached from the support member 11a from below, and particularly when the support member 11a receives force as at least part of the chassis of the vehicle 1000, there is no need to remove the support member 11a, and the battery cells 20 can simply be attached and detached from below the support member 11a, making maintenance of the battery 100 more convenient.

[0337] In some embodiments, the battery cells 20 are glued to the support member 11a.

[0338] Specifically, the battery cells 20 and the support member 11a may be bonded using an adhesive such as an epoxy resin adhesive or an acrylate adhesive, but there is no particular limitation to such an adhesive. In this case, bonding the battery cells 20 and the support member 11a not only makes the connection more convenient, but also simplifies the structure of the battery 100.

[0339] FIG. 22 is a structural schematic diagram of a battery cell 20 according to some embodiments of the present application.

[0340] In some embodiments, referring to FIG. 22 , the outer surface of the battery cell 20 facing the support member 11a is a first outer surface m1, and the battery cell 20 includes an electrode terminal 21a, and the electrode terminal 21a is provided on an outer surface of the battery cell 20 other than the first outer surface m1.

[0341] As described above, the electrode terminals 21a are used for electrical connection with the electrode assemblies 23 inside the battery cells 20 in order to output or input electrical energy to or from the battery cells 20. At least a portion of the electrode terminals 21a extends outside the battery cells 20 in order to electrically connect to the outside. The series and parallel connections between the battery cells 20 are realized by connecting the electrode terminals 21a in series and parallel with each other. The electrode terminals 21a have conductivity to realize electrical transmission, and may be aluminum electrodes, copper electrodes, or the like.

[0342] The electrode terminal 21a is provided on an outer surface of the battery cell 20 other than the first outer surface m1. The first outer surface m1 faces the support member 11a and is typically a smooth surface without any protruding or recessed structures such as the electrode terminal 21a or a fluid filling hole. When the battery cell 20 is suspended from the support member 11a, the first outer surface m1 is the outer surface of the battery cell 20 facing upward. Specifically, in one embodiment, the battery cell 20 includes the above-described case 22 and end cap 21, and the case 22 and end cap 21 form an internal environment of the battery cell 20 that houses the electrode assembly 23. When the end cap 21 is located at one end of the case 22 and the electrode terminal 21a is provided on the end cap 21, any outer surface of the case 22 may be used as the first outer surface m1 of the battery cell 20.

[0343] The electrode terminal 21a includes a positive terminal and a negative terminal, the positive terminal being used for electrical connection with the positive electrode sheet of the electrode assembly 23, and the negative terminal being used for electrical connection with the negative electrode sheet of the electrode assembly 23. The positive and negative terminals may be provided on the same outer surface of the battery cell 20 (e.g., a prismatic battery cell), or may be provided on two different outer surfaces of the battery cell 20 (e.g., a cylindrical battery cell). When the positive and negative terminals are provided on two different outer surfaces of the battery cell 20, the first outer surface m1 is a surface of the battery cell 20 that is different from the two outer surfaces.

[0344] In addition to the battery cells 20, the battery 100 typically includes components such as a sampling wire harness electrically connected to each battery cell 20, a high-voltage wire harness, and a shielding structure for protecting the battery cells 20. In this case, when the electrode terminal 21a is disposed on a surface other than the first outer surface m1 of the battery cell 20 and components such as the sampling wire harness, high-voltage wire harness, and shielding structure are connected to the electrode terminal 21a, each component can be disposed in the space between the battery cell 20 and other structures other than the support member 11a of the main body 11 (for example, the space between the battery cell 20 and the bottom cover 11c and / or the space between the battery cell 20 and the inner surface of the main body 11) without being restricted by the support member 11a, making installation of each component more convenient. At the same time, since the first outer surface m1 is a smooth surface, the first outer surface m1 and the support member 11a can be bonded together, thereby realizing bonding between the battery cell 20 and the support member 11a, eliminating the need to reserve space between the battery cell 20 and the support member 11a, and improving the space utilization rate of the battery 100.

[0345] In some embodiments, referring to FIG. 22, the battery cell 20 has a second outer surface m2 provided opposite to the first outer surface m1, and the electrode terminal 21a is provided on the second outer surface.

[0346] The second outer surface m2 is an outer surface that faces away from the first outer surface m1 of the battery cell 20, and when the battery cell 20 is suspended from the support member 11a, the second outer surface m2 faces the bottom cover 11c.

[0347] Furthermore, the battery cell 20 and the bottom cover 11c can be arranged with a gap between them, in which case it is possible to avoid an external force hitting the bottom cover 11c being transmitted to the battery cell 20 and damaging the battery cell 20. In particular, if the battery 100 is attached to the bottom of the vehicle 1000 and the bottom cover 11c is located at the lowest part of the battery 100, stones and the like from the ground are likely to fly onto the bottom of the battery 100 while the vehicle 1000 is moving and collide with the bottom cover 11c; in this case, the buffer space can block the effect on the battery cell 20 of the external force transmitted to it.

[0348] When the battery cell 20 and the bottom cover 11c are spaced apart, a buffer space is formed between the second outer surface m2 and the bottom cover 11c, and the portion of the electrode terminal 21a extending from the battery cell 20 is located within this buffer space. Thus, the wiring harness and connection sheet connected to the electrode terminal 21a can be placed within the buffer space. At the same time, as described above, the buffer space prevents external force impinging on the bottom cover 11c from acting on the battery cell 20 and damaging the battery cell 20. Therefore, the buffer space not only blocks the effects of external force, but also allows for the routing of wiring harnesses and the like, killing two birds with one stone. It also improves the space utilization of the buffer space and the battery 100.

[0349] In another aspect, the present application further provides an electric device, which includes the battery 100 according to any of the above embodiments, and the battery 100 is used to supply electric energy to the electric device. Please refer to the above introduction of the electric device, and the description will not be repeated here.

[0350] Since the electrical device includes the battery 100, it has all the beneficial effects of the above embodiments, which will not be repeated here.

[0351] FIG. 1 is a schematic diagram of a battery 100 according to some embodiments of the present application applied to a vehicle body 200. As shown in FIG.

[0352] In some embodiments, the electric device includes a vehicle 1000, and the battery 100 is located at the bottom of the body 200 of the vehicle 1000. The vehicle 1000 has been described above and will not be described again here.

[0353] The body 200 of the vehicle 1000 refers to the part of the vehicle 1000 where people and luggage are carried, and includes the driver's seat, passenger compartment, engine compartment, trunk, etc. The body 200 generally includes a housing and doors, windows, trim, seats 300, air conditioning equipment, etc. provided in the housing. The housing generally refers to a structure consisting of the main load-bearing elements of the vehicle 1000, such as longitudinal beams, lateral beams, chassis, and struts, and sheet metal parts connected thereto. In the embodiments of the present application, providing the battery 100 at the bottom of the body 200 mainly means providing the battery 100 at the bottom of the housing.

[0354] In this case, since the battery 100 is provided at the bottom of the vehicle body 200, it does not occupy space inside the vehicle body 200, which contributes to reducing the volume and weight of the vehicle body 200.

[0355] 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 vehicle body 200 chassis.

[0356] The chassis is part of the vehicle body 200 and is composed of a combination of four parts: the transmission system, the driving system, the steering system, and the braking system. It supports and mounts the engine of the vehicle 1000 and its various parts and assemblies, forms the overall structure of the vehicle 1000, withstands the engine power, and ensures normal driving.

[0357] Chassis is a car Body Located at the bottom of the case Body The top portion is directly at least part of the chassis, i.e., the top portion of the housing 10 is used to form at least part of the chassis of the vehicle body 200. In this way, the top portion of the housing 10 and the chassis of the vehicle body 200 are integrated, and the space occupied by the gap between the traditional chassis and the battery 100 is accommodated within the battery 100, thereby increasing the space of the battery 100, thereby increasing the energy of the battery 100, and further improving the driving range of the vehicle 100.

[0358] According to some embodiments of the present application, the electric device includes a vehicle 1000, and a battery 100 is provided at the bottom of a body 200 of the vehicle 1000. The battery 100 includes a housing 10 and a battery cell 20, the housing 10 includes a support member 11a located at the top thereof, the battery cell 20 is located within the housing 10 and suspended from the support member 11a, and the electrode terminal 21a of the battery cell 20 is located on an outer surface of the battery cell 20 away from the support member 11a, and the support member 11a forms at least a part of the chassis of the vehicle 1000. In this case, 20 battery cells are suspended only from the support member 11a, which improves the strength of the support member 11a and further improves the top strength of the battery cells 20, thereby meeting certain stress needs when the support member 11a is used as a chassis. At the same time, because the electrode terminals 21a of the battery cells 20 are spaced apart from the support member 11a, the battery cells 20 can be directly attached to the support member 11a, eliminating the gap between the battery cells 20 and the support member 11a. The saved space can be used to increase the installation space of the battery cells 20, thereby increasing the energy of the battery 100 and further improving the driving range of the vehicle 1000.
