[0003] The present application belongs to the field of automobile technology, and more specifically, relates to a vehicle body and a vehicle. Background Art

[0004] With the rapid development of new energy technologies, electric vehicles are becoming increasingly popular. Electric vehicles consist of a vehicle body, which includes a main frame and batteries. To improve the structural strength of the vehicle body and the energy density of the battery, the main frame and battery are typically integrated. However, this reduces the battery's sealing performance, hindering the safety of electric vehicles.

[0005] Summary of the Invention

[0006] One of the purposes of the embodiments of the present application is to provide a vehicle body and a vehicle to solve the technical problem of poor sealing performance of the battery of the vehicle in the related art.

[0007] To achieve the above-mentioned purpose, the technical solution adopted in the embodiment of the present application is to provide a vehicle body, comprising:

[0008] Main frame;

[0009] The battery comprises a battery cell and an outer frame mounted on the main frame, wherein the outer frame has a cavity for accommodating the battery cell;

[0010] The floor is covered on the outer frame to seal the cavity;

[0011] A first sealing member is arranged in an annular manner in the cavity, and a portion of the floor cooperates with the outer frame to clamp the first sealing member to form a first sealing interface;

[0012] A second sealing member is arranged in an annular manner in the cavity, and another portion of the floor cooperates with the outer frame to clamp the second sealing member to form a second sealing interface;

[0013] The first sealing interface and the second sealing interface are arranged at an angle to each other.

[0014] The vehicle body provided by the embodiment of the present application has at least the following beneficial effects: a part of the floor in the vehicle body provided by the embodiment of the present application cooperates with the outer frame to clamp the first seal to form a first sealing interface, and the other part of the floor cooperates with the outer frame to clamp the second seal to form a second sealing interface, and the first sealing interface and the second sealing interface are arranged at an angle to each other, that is, the sealing direction of the first sealing interface is different from the sealing direction of the second sealing interface. In this way, when the vehicle body vibrates in a direction perpendicular to the first sealing interface, the second seal can be relied on to seal the gap between the outer frame and the floor. When the vehicle body vibrates in a direction perpendicular to the second sealing interface, the first seal can be relied on to seal the gap between the outer frame and the floor, thereby effectively reducing the risk of sealing failure between the outer frame and the floor due to vibration of the vehicle body, and effectively improving the sealing performance of the battery.

[0015] In some embodiments of the present application, the floor includes a plate body covered on an outer frame and a bent portion arranged around the plate body, the outer frame has a first pressing surface and a second pressing surface arranged at an angle to each other, the plate body and the first pressing surface cooperate to clamp the first seal to form a first sealing interface, and the bent portion and the second pressing surface cooperate to clamp the second seal to form a second sealing interface.

[0016] By adopting the above technical solution, it is convenient to form a first sealing interface and a second sealing interface between the outer frame and the floor.

[0017] In some embodiments of the present application, the first pressing surface is perpendicular to the height direction of the vehicle body.

[0018] By adopting the above technical solution, not only is it convenient to assemble the outer frame and the floor, but it is also easier to control the compression amount of the first seal. When the vehicle body does not vibrate in the height direction, the first seal can effectively seal the gap between the outer frame and the plate, effectively improving the sealing performance of the battery. When the vehicle body vibrates in the height direction, the second seal can be relied upon to seal the gap between the outer frame and the floor, thereby effectively reducing the risk of sealing failure between the outer frame and the floor due to vibration of the vehicle body, and further improving the sealing performance of the battery.

[0019] In some embodiments of the present application, the angle formed by the first pressing surface and the second pressing surface is an obtuse angle.

[0020] By adopting the above technical solution, it is convenient to arrange the floor cover on the outer frame and make the bent portion cooperate with the second pressing surface to clamp the second sealing member.

[0021] In some embodiments of the present application, the angle formed by the first pressing surface and the second pressing surface is 95°-120°.

[0022] By adopting the above technical solution, it is not only convenient to set the floor cover on the outer frame, but also can improve the situation where the compression amount of the second seal changes when the vehicle body vibrates in the height direction, thereby reducing the risk of sealing failure between the outer frame and the floor due to vibration of the vehicle body.

[0023] In some embodiments of the present application, the angle formed by the first pressing surface and the second pressing surface is a right angle.

[0024] By adopting the above technical solution, when the vehicle body vibrates along the height direction, the compression amount of the first seal will change significantly, while the compression amount of the second seal will hardly change. Therefore, the second seal can be relied upon to seal the gap between the outer frame and the floor. When the vehicle body vibrates along a direction perpendicular to its height direction, the compression amount of the second seal will change significantly, while the compression amount of the first seal will hardly change. Therefore, the first seal can be relied upon to seal the gap between the outer frame and the floor, thereby effectively reducing the risk of sealing failure between the outer frame and the floor due to vibration of the vehicle body and effectively improving the sealing performance of the battery.

[0025] In some embodiments of the present application, the plate body has a third pressing surface arranged opposite to the first pressing surface, the third pressing surface is parallel to the first pressing surface and cooperates with the first pressing surface to clamp the first seal; and / or the bent portion has a fourth pressing surface arranged opposite to the second pressing surface, the fourth pressing surface is parallel to the second pressing surface and cooperates with the second pressing surface to clamp the second seal.

[0026] By adopting the above technical solution, the extrusion force of the plate body and the outer frame on the first seal and the extrusion force of the bent portion and the outer frame on the second seal are effectively increased, thereby effectively increasing the compression amount of the first seal and the compression amount of the second seal, further reducing the risk of sealing failure between the outer frame and the floor due to vibration of the vehicle body, and further improving the sealing performance of the battery.

[0030] By adopting the above technical solution, the gap between the plate body and the main frame is effectively sealed, thereby effectively isolating the cavity of the outer frame from the external environment of the main frame, further improving the sealing performance of the battery.

[0031] In some embodiments of the present application, the floor further includes a second connecting portion connected between the bent portion and the main frame.

[0032] By adopting the above technical solution, under the support of the main frame, the extrusion force of the bent portion on the second seal is effectively increased, thereby effectively increasing the compression amount of the second seal, further reducing the risk of sealing failure between the outer frame and the floor due to vibration of the vehicle body, and further improving the sealing performance of the battery.

[0035] In some embodiments of the present application, the first sealing member is disposed on the top of the outer frame; and / or the second sealing member is disposed on a side of the outer frame facing away from the cavity.

[0036] By adopting the above technical solution, the sealing structure between the outer frame and the floor does not need to occupy the internal space of the outer frame cavity, effectively improving the space utilization of the outer frame cavity, thereby effectively improving the volume energy density of the battery.

[0037] In some embodiments of the present application, a first limiting groove is formed in the outer frame or the floor, and at least a portion of the first sealing member is accommodated in the first limiting groove.

[0038] By adopting the above technical solution, the position of the first seal is effectively limited to improve the situation where the first seal shifts when the vehicle body vibrates, thereby further reducing the risk of sealing failure between the outer frame and the floor due to vehicle body vibration, and further improving the sealing performance of the battery.

DETAILED DESCRIPTION

[0061] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0062] It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be directly on the other component or indirectly on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The terms "upper", "lower", "left", "right", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of description and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on this application. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to the specific circumstances. The terms "first" and "second" are only used for the purpose of convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[0063] In the embodiments of the present application, the same reference numerals represent the same components, and for the sake of brevity, detailed descriptions of the same components in different embodiments are omitted. It should be understood that the thickness, length, width, and other dimensions of the various components in the embodiments of the present application shown in the drawings are for illustrative purposes only and should not constitute any limitation on the present application.

[0064] An electric vehicle is a vehicle that relies on electricity as its power source for all or part of its operating conditions. An electric vehicle comprises a vehicle body, which includes a main frame, a battery, and a floor. The main frame is the primary component of the vehicle body, supporting and reinforcing the entire vehicle body. Batteries typically consist of a single cell and an outer frame, wherein a single cell is the smallest unit that makes up the battery. The outer frame is mounted on the main frame and has a cavity within which the single cell is housed. The floor is mounted on the main frame and serves to provide an installation environment for components located within the cockpit of the electric vehicle. The floor also supports these components as well as the driver and passengers.

[0065] In the related art, in order to improve the structural strength of the vehicle body and the energy density of the battery, the floor is usually used as a cover for the battery and is placed on the outer frame to block the cavity of the outer frame, thereby realizing an integrated design of the vehicle body. At the same time, in order to improve the sealing performance of the battery, a seal is usually provided between the outer frame and the floor to block the gap between the outer frame and the floor. However, during the driving of an electric vehicle, the vehicle body is prone to vibration. When the vibration direction of the vehicle body is the same or approximately the same as the assembly direction of the outer frame and the floor, the outer frame and the floor will move relative to each other with the vibration of the vehicle body, resulting in a large change in the compression amount of the seal, which can easily lead to a seal failure between the outer frame and the floor, thereby significantly reducing the sealing performance of the battery.

[0066] In order to improve the sealing performance of batteries in electric vehicles, a part of the floor in the vehicle body provided in the embodiment of the present application cooperates with the outer frame to clamp the first seal to form a first sealing interface, and the other part of the floor cooperates with the outer frame to clamp the second seal to form a second sealing interface. The first sealing interface and the second sealing interface are arranged at an angle to each other, that is, the sealing direction of the first sealing interface is different from the sealing direction of the second sealing interface. In this way, when the vehicle body vibrates in a direction perpendicular to the first sealing interface, the second seal can be relied on to seal the gap between the outer frame and the floor. When the vehicle body vibrates in a direction perpendicular to the second sealing interface, the first seal can be relied on to seal the gap between the outer frame and the floor, thereby effectively reducing the risk of sealing failure between the outer frame and the floor due to vibration of the vehicle body and effectively improving the sealing performance of the battery.

[0067] The vehicle disclosed in the embodiments of the present application may be a fuel vehicle, a gas vehicle or a new energy vehicle, wherein the new energy vehicle may be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. The vehicle includes a body, which is the main supporting component of the vehicle. In some embodiments, the body may be an integrated body. The body has an engine cabin and a driver's cabin, wherein the engine cabin is used to accommodate the vehicle's power unit, transmission device, cooling device, etc., and the driver's cabin is used to provide operating space and riding space for the driver and passengers. In the case where the vehicle is a front-wheel drive vehicle, the engine cabin is arranged at the front of the vehicle body, that is, the engine cabin is the front engine cabin; in the case where the vehicle is a rear-wheel drive vehicle, the engine cabin is arranged at the rear of the vehicle body, that is, the engine cabin is the rear engine cabin; in the case where the vehicle is a four-wheel drive vehicle, the engine cabin is divided into a front engine cabin and a rear engine cabin, the front engine cabin is arranged at the front of the vehicle body, and the rear engine cabin is arranged at the rear of the vehicle body. The driver's cabin is arranged between the front and rear of the vehicle body.

[0068] The vehicle body provided in the embodiment of the present application is described below with reference to the accompanying drawings.

[0069] In the first aspect, referring to Figures 1 to 8 , an embodiment of the present application provides a vehicle body 1000 comprising a main frame 100, a battery 200, a floor panel 300, a first seal 400, and a second seal 500. The battery 200 comprises a battery cell (not shown) and an outer frame 210 mounted on the main frame 100. The outer frame 210 has a cavity 211 for accommodating the battery cell. The floor panel 300 is mounted on the outer frame 210 to seal the cavity 211. The first seal 400 is disposed around the cavity 211. A portion of the floor panel 300 cooperates with the outer frame 210 to clamp the first seal 400 to form a first sealing interface 410. The second seal 500 is disposed around the cavity 211. Another portion of the floor panel 300 cooperates with the outer frame 210 to clamp the second seal 500 to form a second sealing interface 510. The first sealing interface 410 and the second sealing interface 510 are arranged at an angle to each other.

[0070] For the convenience of description below, the direction parallel to the axial direction of the vehicle's wheels is defined as the width direction of the vehicle body 1000. It should be noted that the above-mentioned axial direction refers to the axial direction of the wheels when the vehicle is traveling along any straight line, such as the Y direction as shown in Figures 1 to 8. The direction perpendicular to the above-mentioned axial direction and parallel to the support plane of the vehicle is defined as the length direction of the vehicle body 1000. It should be noted that the above-mentioned support plane refers to the plane of the wheel surface on the side facing away from the vehicle body 1000 that is tangent to all wheels of the vehicle when the vehicle is in a driving state or a stationary state, such as the X direction as shown in Figures 1 and 2. The direction perpendicular to the above-mentioned width direction and the above-mentioned length direction is defined as the height direction of the vehicle body 1000, such as the Z direction as shown in Figures 1 and 3 to 8. The two sides of the body 1000 along its width direction are the left side and the right side of the body 1000, the two sides of the body 1000 along its length direction are the front side and the rear side of the body 1000, and the two sides of the body 1000 along its height direction are the bottom and the top of the body 1000, wherein the bottom is the part of the body 1000 facing the above-mentioned support plane, and the top is the part of the body 1000 facing away from the above-mentioned support plane. Similarly, the two sides of the outer frame 210 along the height direction of the body 1000 are the bottom and the top of the outer frame 210, wherein the bottom is the part of the outer frame 210 facing the above-mentioned support plane, and the top is the part of the outer frame 210 facing away from the above-mentioned support plane.

[0071] The main frame 100 is the primary supporting component of the vehicle body 1000, serving to support and reinforce the entire vehicle body 1000. The main frame 100 is made of a rigid material, which may include, but is not limited to, aluminum, aluminum alloy, iron, stainless steel, and the like. In some embodiments, the main frame 100 includes a front beam, a rear beam, and two sill beams. The front beam, one sill beam, the rear beam, and the other sill beam are connected end-to-end to form the main frame 100. The front beam and the rear beam are spaced apart along the length of the vehicle body 1000. The front beam and the rear beam may be linear and extend along the width of the vehicle body 1000, or they may be curved and extend in a zigzag manner along the width of the vehicle body 1000. One sill beam is disposed on the left side of the vehicle body 1000, and the other sill beam is disposed on the right side of the vehicle body 1000. In the height direction of the vehicle body 1000, the sill beams are located below the vehicle doors. The two sill beams can be straight and extend along the length of the vehicle body 1000, or they can be curved and extend in a zigzag manner along the length of the vehicle body 1000. In some embodiments, the front beam, rear beam, and two sill beams can be integrally formed components, for example, the front beam, rear beam, and two sill beams can be integrally formed using a die-casting process. In other embodiments, the front beam, rear beam, and two sill beams can be separate components, for example, the front beam, rear beam, and two sill beams can be separately formed and then connected to form a single unit. In some embodiments, to reduce the weight of the vehicle body 1000, the front beam, rear beam, and two sill beams can be hollow structures, i.e., the interiors of the front beam, rear beam, and two sill beams have cavities formed therein.

[0072] In some embodiments, the vehicle body 1000 may further include a front frame 700 and a rear frame 800. The front frame 700 is disposed on the front side of the vehicle body 1000 and connected to the side of the front beam facing away from the rear beam. The rear frame 800 is disposed on the rear side of the vehicle body 1000 and connected to the side of the rear beam facing away from the front beam.

[0073] The battery 200 can be mounted on the main frame 100, for example, the battery 200 is mounted on the bottom of the main frame 100. The battery 200 can be used to power the vehicle, for example, the battery 200 can serve as the operating power source of the vehicle. The vehicle may further include a controller (not shown) and a motor (not shown), and the controller is used to control the battery 200 to power the motor, for example, for starting, navigating, and driving the vehicle. In some embodiments, the battery 200 can serve not only as the operating power source of the vehicle, but also as the driving power source of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0074] A battery cell is the smallest storage unit for storing electrical energy. There can be multiple battery cells, and the multiple battery cells can be connected in series, in parallel, or in a mixed connection. Mixed connection means that multiple battery cells are connected in series and in parallel. Multiple battery cells can be directly connected in series, in parallel, or in a mixed connection, and then the whole composed of multiple battery cells is placed in the cavity 211 of the outer frame 210. Of course, the battery 200 can also be a battery module composed of multiple battery cells connected in series, in parallel, or in a mixed connection, and the multiple battery modules are then connected in series, in parallel, or in a mixed connection to form a whole and placed in the cavity 211 of the outer frame 210. The battery 200 may also include other functional components. For example, the battery 200 may also include a convergence component, which is used to achieve electrical connection between multiple battery cells.

[0075] Each battery cell may be a secondary battery or a primary battery. A secondary battery refers to a battery cell that can be recharged to activate the active material after the battery cell is discharged and can continue to be used. A primary battery refers to a battery cell that cannot be recharged to activate the active material after the battery cell's power is exhausted and can continue to be used. The battery cell may also be a lithium-ion battery, a sodium-ion battery, a sodium-lithium-ion battery, a lithium metal battery, a sodium metal battery, a lithium-sulfur battery, a magnesium-ion battery, a nickel-hydrogen battery, a nickel-cadmium battery, a lead-acid battery, etc., but is not limited thereto. The battery cell may be a cylindrical battery cell, a prismatic battery cell, a soft-pack battery cell, or a battery cell of other shapes. Prismatic battery cells include square-shell battery cells, blade-shaped battery cells, and polygonal prismatic battery cells. Polygonal prismatic battery cells are, for example, hexagonal battery cells, etc. This application does not have any special restrictions.

[0076] The outer frame 210 is used to provide an installation environment for the battery cells. The outer frame 210 is made of a rigid material, which may be, but is not limited to, aluminum, aluminum alloy, iron, stainless steel, etc. In some embodiments, the outer frame 210 includes two first support beams and two second support beams. One first support beam is arranged on the left side of the vehicle body 1000, and the other first support beam is arranged on the right side of the vehicle body 1000. The first support beam can be a straight structure and extend along the length direction of the vehicle body 1000, or the first support beam can be a bent structure and extend in a zigzag manner along the length direction of the vehicle body 1000. The two second support beams are arranged at intervals along the length direction of the vehicle body 1000. The second support beam can be a straight structure and extend along the width direction of the vehicle body 1000, or the second support beam can be a bent structure and extend in a zigzag manner along the width direction of the vehicle body 1000. A first support beam, a second support beam, another first support beam, and another second support beam are connected end to end to enclose the above-mentioned cavity 211. The two first support beams are connected to the two threshold beams in a one-to-one correspondence, the one second support beam is connected to the front beam body, and the other second support beam is connected to the rear beam body, so as to install the outer frame 210 on the main frame 100. The connection method between the outer frame 210 and the main frame 100 can be, but is not limited to, welding, fastening connection, etc. In some embodiments, the two first support beams and the two second support beams can be an integrally formed component, for example, the two first support beams and the two second support beams are integrally formed using a die-casting process. In other embodiments, the two first support beams and the two second support beams can be split components, for example, the two first support beams and the two second support beams are separately formed and then connected to each other into a whole. In some embodiments, in order to reduce the weight of the outer frame 210, the first support beam and the second support beam can be a hollow structure, that is, a cavity is formed inside the first support beam and inside the second support beam.

[0077] In some embodiments, the battery 200 further includes a protective plate 220, a floor panel 300 covering one side of the outer frame 210 along the height direction of the vehicle body 1000, and a protective plate 220 covering the other side of the outer frame 210 along the height direction of the vehicle body 1000. For example, the floor panel 300 covers the top of the outer frame 210, and the protective plate 220 covers the bottom of the outer frame 210 to isolate the cavity 211 of the outer frame 210 from the external environment of the battery 200. The protective plate 220 can serve as a heat exchange component of the battery 200, used to perform heat exchange operations on the battery cells.

[0078] The floor panel 300 provides mounting space for components within the vehicle's cockpit. For example, the vehicle's seats are mounted on the floor panel 300. The floor panel 300 also supports these components and the driver and passengers. In this embodiment, the floor panel 300 serves as a cover for the battery 200 and is mounted on the outer frame 210 to seal the cavity 211 within the outer frame 210, thereby achieving an integrated design for the vehicle body 1000. The floor panel 300 may or may not be connected to the outer frame 210. In some embodiments, the floor panel 300 is mounted on the main frame 100. One side of the floor panel 300 along the width of the vehicle body 1000 is connected to one sill beam, and the other side of the floor panel 300 along the width of the vehicle body 1000 is connected to another sill beam. One side of the floor panel 300 along the length of the vehicle body 1000 is connected to the front beam, and the other side of the floor panel 300 along the length of the vehicle body 1000 is connected to the rear beam. The connection between the floor panel 300 and the main frame 100 may be, but is not limited to, welding, fastening, or bonding. The floor panel 300 is made of a rigid material, which may include, but is not limited to, aluminum, aluminum alloys, iron, stainless steel, and the like. In some embodiments, the floor panel 300 may be a one-piece component, for example, formed integrally via a die-casting process. In other embodiments, the floor panel 300 may be a separate component, for example, comprising multiple parts that are individually molded and then connected to form a single unit.

[0079] The first seal 400 and the second seal 500 are used to seal the gap between the outer frame 210 and the floor 300. In some embodiments, the first seal 400 and the second seal 500 are annular and arranged around the cavity 211. It is understood that the first seal 400 and the second seal 500 are disposed at different locations on the floor 300. A portion of the floor 300 cooperates with the outer frame 210 to clamp the first seal 400 to form a first sealing interface 410, while another portion of the floor 300 cooperates with the outer frame 210 to clamp the second seal 500 to form a second sealing interface 510. The first seal 400 and the second seal 500 can be made of a flexible material, such as, but not limited to, rubber, silicone, etc.

[0080] The first sealing interface 410 refers to the interface between a portion of the floor panel 300 and the outer frame 210. The first sealing interface 410 can be flat or curved, depending on the shape of the pressure-bearing portion of the first seal 400. In some embodiments, the first sealing interface 410 is flat and perpendicular to the direction of the compressive force exerted on the first seal 400 by the floor panel 300 and the outer frame 210. When the first seal 400 is clamped, foreign objects cannot enter the cavity 211 of the outer frame 210 in a direction parallel to the first sealing interface 410.

[0081] The second sealing interface 510 refers to the interface between the other portion of the floor panel 300 and the outer frame 210. The second sealing interface 510 can be flat or curved, depending on the shape of the pressure-bearing portion of the second sealing member 500. In some embodiments, the second sealing interface 510 is flat and perpendicular to the direction of the compressive force exerted on the second sealing member 500 by the floor panel 300 and the outer frame 210. When the second sealing member 500 is clamped, foreign objects cannot enter the cavity 211 of the outer frame 210 in a direction parallel to the second sealing interface 510.

[0082] The first sealing interface 410 and the second sealing interface 510 are arranged at an angle to each other. That is, the first sealing interface 410 and the second sealing interface 510 are not parallel to each other, and the sealing direction of the first sealing interface 410 is different from the sealing direction of the second sealing interface 510. In other words, at least two sealing structures are provided between the floor panel 300 and the outer frame 210, and the sealing directions of at least two sealing structures are different.

[0083] In the vehicle body 1000 provided in the embodiment of the present application, a portion of the floor panel 300 cooperates with the outer frame 210 to clamp the first seal 400 to form a first sealing interface 410, and another portion of the floor panel 300 cooperates with the outer frame 210 to clamp the second seal 500 to form a second sealing interface 510. The first sealing interface 410 and the second sealing interface 510 are arranged at an angle to each other, that is, the sealing direction of the first sealing interface 410 is different from the sealing direction of the second sealing interface 510. In this way, when the vehicle body 1000 vibrates in a direction perpendicular to the first sealing interface 410, the second seal 500 can be relied on to seal the gap between the outer frame 210 and the floor panel 300. When the vehicle body 1000 vibrates in a direction perpendicular to the second sealing interface 510, the first seal 400 can be relied on to seal the gap between the outer frame 210 and the floor panel 300. This effectively reduces the risk of sealing failure between the outer frame 210 and the floor panel 300 due to vibration of the vehicle body 1000, and effectively improves the sealing performance of the battery 200.

[0084] In some embodiments of the present application, please refer to Figures 3 to 8. The floor 300 includes a plate body 310 covered on the outer frame 210 and a bent portion 320 arranged around the plate body 310. The outer frame 210 has a first pressing surface 212 and a second pressing surface 213 arranged at an angle to each other. The plate body 310 and the first pressing surface 212 cooperate to clamp the first sealing member 400 to form a first sealing interface 410. The bent portion 320 and the second pressing surface 213 cooperate to clamp the second sealing member 500 to form a second sealing interface 510.

[0085] The plate body 310 is the main part of the floor 300, which is used to seal the cavity 211 of the outer frame 210. The plate body 310 can be a straight structure or a curved structure. The bending portion 320 is a portion that is bent in a preset direction relative to the plate body 310, that is, the bending portion 320 and the plate body 310 are arranged at an angle to each other. In some embodiments, the bending portion 320 and the plate body 310 can be an integrally formed component. For example, the bending portion 320 and the plate body 310 are integrally formed using a stamping process. In other embodiments, the bending portion 320 and the plate body 310 are separately formed and then connected to each other into a whole. The connection method between the bending portion 320 and the plate body 310 can be, but is not limited to, welding, fastening connection, bonding, etc.

[0086] The first pressing surface 212 is used to support the first sealing member 400. The first pressing surface 212 can be a flat surface. When the floor panel 300 is covered on the outer frame 210, the first pressing surface 212 is disposed opposite the plate body 310. The first pressing surface 212 and the plate body 310 cooperate to clamp the first sealing member 400 to form a first sealing interface 410. The second pressing surface 213 is used to support the second sealing member 500. The second pressing surface 213 can be a flat surface. When the floor panel 300 is covered on the outer frame 210, the second pressing surface 213 is disposed opposite the bent portion 320. The second pressing surface 213 and the bent portion 320 cooperate to clamp the second sealing member 500 to form a second sealing interface 510. In other words, the first pressing surface 212 and the second pressing surface 213 are not parallel to each other, so that a first sealing interface 410 and a second sealing interface 510 that are not parallel to each other can be formed between the outer frame 210 and the floor 300.

[0087] In some embodiments, the first seal 400 includes two first seals spaced apart along the width direction of the vehicle body 1000 and two second seals spaced apart along the length direction of the vehicle body 1000. The second seal 500 includes two third seals spaced apart along the width direction of the vehicle body 1000 and two fourth seals spaced apart along the length direction of the vehicle body 1000. When the outer frame 210 includes two first support beams and two second support beams, the two first support beams and the two second support beams are each provided with a first pressing surface 212 and a second pressing surface 213. The first pressing surface 212 of a first support beam cooperates with the plate body 310 to clamp a first sealing body, the first pressing surface 212 of another first support beam cooperates with the plate body 310 to clamp another first sealing body, the first pressing surface 212 of a second support beam cooperates with the plate body 310 to clamp a second sealing body, the first pressing surface 212 of another second support beam cooperates with the plate body 310 to clamp another second sealing body. Similarly, the second pressing surface 213 of a first support beam cooperates with the bending portion 320 to clamp a third sealing body, the second pressing surface 213 of another first support beam cooperates with the bending portion 320 to clamp another third sealing body, the second pressing surface 213 of a second support beam cooperates with the bending portion 320 to clamp a fourth sealing body, and the second pressing surface 213 of another second support beam cooperates with the bending portion 320 to clamp another fourth sealing body.

[0088] By adopting the above technical solution, a first sealing interface 410 and a second sealing interface 510 are formed between the outer frame 210 and the floor 300 .

[0089] In some embodiments of the present application, please refer to FIG. 3 to FIG. 8 , the first pressing surface 212 is perpendicular to the height direction of the vehicle body 1000 .

[0090] During the assembly process of the vehicle body 1000, the floor 300 can be placed on the outer frame 210 along the height direction of the vehicle body 1000, so that the plate 310 and the outer frame 210 cooperate to clamp the first seal 400 along the height direction of the vehicle body 1000. By adjusting the distance between the floor 300 and the outer frame 210 along the height direction of the vehicle body 1000, the compression amount of the first seal 400 can be adjusted.

[0091] By adopting the above technical solution, not only is it convenient to assemble the outer frame 210 and the floor 300, but it is also easier to control the compression amount of the first seal 400. When the vehicle body 1000 does not vibrate in the height direction, the first seal 400 can effectively seal the gap between the outer frame 210 and the plate 310, effectively improving the sealing performance of the battery 200. When the vehicle body 1000 vibrates in the height direction, the second seal 500 can be relied on to seal the gap between the outer frame 210 and the floor 300, thereby effectively reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0092] In some embodiments of the present application, referring to FIG. 3 and FIG. 4 , the angle α formed by the first pressing surface 212 and the second pressing surface 213 is an obtuse angle.

[0093] In some embodiments, the first pressing surface 212 is formed on the top of the outer frame 210, and the second pressing surface 213 is formed on the side of the outer frame 210 facing away from the cavity 211. The second pressing surface 213 is connected to the first pressing surface 212, and the second pressing surface 213 is inclined from the first pressing surface 212 toward the direction of the cavity 211 away from the outer frame 210, so that the angle α formed by the first pressing surface 212 and the second pressing surface 213 is an obtuse angle.

[0094] In other embodiments, the first pressing surface 212 is formed on the top of the outer frame 210, and the second pressing surface 213 is formed on the side of the outer frame 210 facing the cavity 211. The second pressing surface 213 is connected to the first pressing surface 212, and the second pressing surface 213 is inclined from the first pressing surface 212 toward the cavity 211 close to the outer frame 210, so that the angle α formed by the first pressing surface 212 and the second pressing surface 213 is an obtuse angle.

[0095] During the assembly process of the vehicle body 1000, the floor 300 can be covered on the outer frame 210 along the height direction of the vehicle body 1000, so that the plate body 310 and the outer frame 210 cooperate to clamp the first seal 400 along the height direction of the vehicle body 1000, and the bent portion 320 cooperates with the second pressing surface 213 along the inclined direction of the second pressing surface 213 to clamp the second seal 500, thereby completing the assembly operation of the outer frame 210 and the floor 300.

[0096] By adopting the above technical solution, it is convenient to cover the floor panel 300 on the outer frame 210 and make the bent portion 320 cooperate with the second pressing surface 213 to clamp the second sealing member 500 .

[0097] In some embodiments of the present application, referring to FIG. 4 , the angle α formed by the first pressing surface 212 and the second pressing surface 213 is 95°-120°.

[0098] The angle α formed by the first pressing surface 212 and the second pressing surface 213 can be determined according to actual application requirements, and can be specifically 95°, 100°, 105°, 110°, 115°, 120°, etc.

[0099] By adopting the above technical solution, it is not only convenient to cover the floor 300 on the outer frame 210, but also the situation in which the compression amount of the second seal 500 changes when the vehicle body 1000 vibrates in the height direction can be improved, thereby reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000.

[0100] In some embodiments of the present application, referring to FIG. 5 and FIG. 6 , the angle α formed by the first pressing surface 212 and the second pressing surface 213 is a right angle.

[0101] In other words, the first pressing surface 212 is perpendicular to the height direction of the vehicle body 1000 , and the second pressing surface 213 is parallel to the height direction of the vehicle body 1000 .

[0102] By adopting the above technical solution, when the vehicle body 1000 vibrates in the height direction, the compression amount of the first seal 400 will change significantly, while the compression amount of the second seal 500 will hardly change. Therefore, the second seal 500 can be relied on to seal the gap between the outer frame 210 and the floor 300. When the vehicle body 1000 vibrates in a direction perpendicular to its height direction, the compression amount of the second seal 500 will change significantly, while the compression amount of the first seal 400 will hardly change. Therefore, the first seal 400 can be relied on to seal the gap between the outer frame 210 and the floor 300, thereby effectively reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000 and effectively improving the sealing performance of the battery 200.

[0103] In some embodiments of the present application, please refer to Figures 4, 6 and 8. The plate body 310 has a third pressing surface 311 arranged opposite to the first pressing surface 212. The third pressing surface 311 is parallel to the first pressing surface 212 and cooperates with the first pressing surface 212 to clamp the first sealing member 400.

[0104] The third pressing surface 311 is a portion used to squeeze the first sealing member 400. When the floor 300 is covered on the outer frame 210, the first pressing surface 212 and the third pressing surface 311 are arranged opposite to each other. The first pressing surface 212 and the third pressing surface 311 cooperate to clamp the first sealing member 400 to form a first sealing interface 410.

[0105] In some embodiments, the first pressing surface 212 and the third pressing surface 311 are planes, and the first pressing surface 212 and the third pressing surface 311 are parallel to each other. When the first pressing surface 212 and the third pressing surface 311 cooperate to clamp the first seal 400, the direction of the extrusion force exerted by the first pressing surface 212 on the first seal 400 is opposite to the direction of the extrusion force exerted by the third pressing surface 311 on the first seal 400, so that the two extrusion forces can be superimposed on each other and act on the first seal 400, thereby effectively increasing the compression amount of the first seal 400.

[0106] By adopting the above technical solution, the extrusion force of the plate 310 and the outer frame 210 on the first seal 400 is effectively increased, thereby effectively increasing the compression amount of the first seal 400, further reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0107] In other embodiments of the present application, please refer to Figures 4, 6 and 8. The bending portion 320 has a fourth pressing surface 321 arranged opposite to the second pressing surface 213. The fourth pressing surface 321 is parallel to the second pressing surface 213 and cooperates with the second pressing surface 213 to clamp the second sealing member 500.

[0108] The fourth pressing surface 321 is a portion used to squeeze the second sealing member 500. When the floor 300 is covered on the outer frame 210, the second pressing surface 213 and the fourth pressing surface 321 are arranged opposite to each other. The second pressing surface 213 and the fourth pressing surface 321 cooperate to clamp the second sealing member 500 to form a second sealing interface 510.

[0109] In some embodiments, the second pressing surface 213 and the fourth pressing surface 321 are planes, and the second pressing surface 213 and the fourth pressing surface 321 are parallel to each other. When the second pressing surface 213 and the fourth pressing surface 321 cooperate to clamp the second seal 500, the direction of the extrusion force exerted by the second pressing surface 213 on the second seal 500 is opposite to the direction of the extrusion force exerted by the fourth pressing surface 321 on the second seal 500, so that the two extrusion forces can be superimposed on each other and act on the second seal 500, thereby effectively increasing the compression amount of the second seal 500.

[0110] By adopting the above technical solution, the extrusion force of the bending portion 320 and the outer frame 210 on the second seal 500 is effectively increased, thereby effectively increasing the compression amount of the second seal 500, further reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0111] In some other embodiments of the present application, please refer to Figures 4, 6 and 8. The plate body 310 has a third pressing surface 311 arranged opposite to the first pressing surface 212. The third pressing surface 311 is parallel to the first pressing surface 212 and cooperates with the first pressing surface 212 to clamp the first seal 400. The bending portion 320 has a fourth pressing surface 321 arranged opposite to the second pressing surface 213. The fourth pressing surface 321 is parallel to the second pressing surface 213 and cooperates with the second pressing surface 213 to clamp the second seal 500.

[0112] By adopting the above technical solution, the extrusion force of the plate body 310 and the outer frame 210 on the first seal 400 and the extrusion force of the bending portion 320 and the outer frame 210 on the second seal 500 are effectively increased, thereby effectively increasing the compression amount of the first seal 400 and the compression amount of the second seal 500, further reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0113] In some embodiments of the present application, please refer to FIG. 4 , FIG. 6 and FIG. 8 . The floor panel 300 further includes a first connecting portion 330 . The first connecting portion 330 is connected between the panel body 310 and the main frame 100 .

[0114] The first connecting portion 330 is used to connect the plate body 310 and the main frame 100. In some embodiments, the first connecting portion 330 and the plate body 310 are integrally formed components. For example, the first connecting portion 330 and the plate body 310 are integrally formed using a stamping process. In other embodiments, the first connecting portion 330 and the plate body 310 are separately formed and then connected to form a single unit. The connection between the first connecting portion 330 and the plate body 310 may be, but is not limited to, welding, fastening, or bonding. The connection between the first connecting portion 330 and the main frame 100 may be, but is not limited to, welding, fastening, or bonding.

[0115] By adopting the above technical solution, under the support of the main frame 100, the extrusion force of the plate 310 on the first seal 400 is effectively increased, thereby effectively increasing the compression amount of the first seal 400, further reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0116] In some embodiments of the present application, the first connection portion 330 is annularly disposed on the plate body 310 , the inner ring side of the first connection portion 330 is connected to the plate body 310 , and the outer ring side of the first connection portion 330 is connected to the main frame 100 .

[0117] In some embodiments, the first connecting portion 330 is an annular plate structure, and the first connecting portion 330 covers the gap between the plate body 310 and the main frame 100. The inner ring side of the first connecting portion 330 is connected to the plate body 310, and the outer ring side of the first connecting portion 330 is connected to the main frame 100 to seal the gap between the plate body 310 and the main frame 100.

[0118] By adopting the above technical solution, the gap between the plate body 310 and the main frame 100 is effectively blocked, thereby effectively isolating the cavity 211 of the outer frame 210 from the external environment of the main frame 100, further improving the sealing performance of the battery 200.

[0119] In some embodiments of the present application, please refer to FIG. 4 , FIG. 6 and FIG. 8 . The floor panel 300 further includes a second connecting portion 340 . The second connecting portion 340 is connected between the bending portion 320 and the main frame 100 .

[0120] The second connecting portion 340 is used to connect the bent portion 320 to the main frame 100. In some embodiments, the second connecting portion 340 and the bent portion 320 are integrally formed components. For example, the second connecting portion 340 and the bent portion 320 are integrally formed using a stamping process. In other embodiments, the second connecting portion 340 and the bent portion 320 are separately formed and then connected to form a single unit. The connection between the second connecting portion 340 and the bent portion 320 may be, but is not limited to, welding, fastening, or bonding. The connection between the second connecting portion 340 and the main frame 100 may be, but is not limited to, welding, fastening, or bonding.

[0121] By adopting the above technical solution, under the support of the main frame 100, the extrusion force of the bending portion 320 on the second seal 500 is effectively increased, thereby effectively increasing the compression amount of the second seal 500, further reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0125] In some embodiments of the present application, please refer to FIG. 3 to FIG. 8 , the first sealing member 400 is disposed on the top of the outer frame 210 .

[0126] In other words, the first pressing surface 212 is formed on the top of the outer frame 210 , and the first sealing member 400 is disposed on the first pressing surface 212 .

In other words, the bending portion 320 is bent relative to the plate body 310 in a direction close to the above-mentioned support plane.

[0133] By adopting the above technical solution, the sealing structure between the outer frame 210 and the floor 300 does not need to occupy the internal space of the cavity 211 of the outer frame 210, effectively improving the space utilization of the cavity 211 of the outer frame 210, thereby effectively improving the volume energy density of the battery 200.

[0138] By adopting the above technical solution, the position of the first seal 400 is effectively limited to improve the situation where the first seal 400 is shifted when the vehicle body 1000 vibrates, thereby further reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0139] In some embodiments of the present application, please refer to FIG. 7 and FIG. 8 , the outer frame 210 or the floor 300 is provided with a second limiting groove 218 , and at least a portion of the second sealing member 500 is accommodated in the second limiting groove 218 .

[0140] In some embodiments, referring to FIG. 8 , the outer frame 210 is provided with a second limiting groove 218 . The second limiting groove 218 may be formed by the second pressing surface 213 of the outer frame 210 being recessed in a direction away from the bent portion 320 of the floor 300 .

[0141] In other embodiments, the floor panel 300 is provided with a second limiting groove 218 . The second limiting groove 218 may be formed by a side of the bent portion 320 of the floor panel 300 facing the outer frame 210 being recessed in a direction away from the outer frame 210 .

[0142] The second limiting groove 218 may be annular and arranged around the cavity 211 of the outer frame 210 . A portion of the second sealing member 500 is accommodated in the second limiting groove 218 , and another portion of the second sealing member 500 protrudes toward the outside of the second limiting groove 218 .

[0143] By adopting the above technical solution, the position of the second seal 500 is effectively limited to improve the situation where the second seal 500 is shifted when the vehicle body 1000 vibrates, thereby further reducing the risk of sealing failure between the outer frame 210 and the floor 300 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0144] In some embodiments of the present application, please refer to Figures 3 to 8 , the vehicle body 1000 further includes a third sealing member 600 arranged around the cavity 211 , and the main frame 100 and the outer frame 210 cooperate to clamp the third sealing member 600 to form a third sealing interface 610 .

[0145] The third seal 600 is used to seal the gap between the outer frame 210 and the main frame 100. In some embodiments, the third seal 600 has an annular structure and is disposed around the cavity 211. It is understood that the first seal 400, the second seal 500, and the third seal 600 are disposed at different locations on the outer frame 210. A portion of the outer frame 210 cooperates with the floor 300 to clamp the first seal 400 to form a first sealing interface 410. Another portion of the outer frame 210 cooperates with the floor 300 to clamp the second seal 500 to form a second sealing interface 510. Another portion of the outer frame 210 cooperates with the main frame 100 to clamp the third seal 600 to form a third sealing interface 610. The third seal 600 can be made of a flexible material, such as, but not limited to, rubber, silicone, or the like.

[0146] The third sealing interface 610 refers to the interface between the outer frame 210 and the main frame 100. The third sealing interface 610 can be flat or curved, depending on the shape of the pressure-bearing portion of the third sealing member 600. In some embodiments, the third sealing interface 610 is flat and perpendicular to the direction of the compressive force exerted on the third sealing member 600 by the outer frame 210 and the main frame 100. When the third sealing member 600 is clamped, foreign objects cannot enter the space between the outer frame 210 and the main frame 100 in a direction parallel to the third sealing interface 610.

[0147] In some embodiments, the third seal 600 includes two fifth seals spaced apart along the width direction of the vehicle body 1000 and two sixth seals spaced apart along the length direction of the vehicle body 1000. When the outer frame 210 includes two first support beams and two second support beams and the main frame 100 includes a front beam body, a rear beam body, and two door sill beams, one first support beam cooperates with one door sill beam to clamp one fifth seal, another first support beam cooperates with another door sill beam to clamp another fifth seal, one second support beam cooperates with the front beam body to clamp one sixth seal, and another second support beam cooperates with the rear beam body to clamp another sixth seal.

[0148] By adopting the above technical solution, the gap between the outer frame 210 and the main frame 100 is effectively blocked, thereby effectively isolating the cavity 211 of the outer frame 210 from the external environment of the main frame 100, further improving the sealing performance of the battery 200.

[0149] In some embodiments of the present application, referring to FIG. 4 , the third sealing interface 610 is parallel to the first sealing interface 410 .

[0150] The third sealing interface 610 being parallel to the first sealing interface 410 means that the sealing direction of the sealing structure formed between the outer frame 210 and the plate 310 is the same as the sealing direction of the sealing structure formed between the outer frame 210 and the main frame 100 .

[0151] In some embodiments, the outer frame 210 has a first pressing surface 212 and a fifth pressing surface 214, the first seal 400 is arranged on the first pressing surface 212, and the third seal 600 is arranged on the fifth pressing surface 214, and the first pressing surface 212 and the fifth pressing surface 214 are perpendicular to the height direction of the vehicle body 1000.

[0152] By adopting the above technical solution, when the vehicle body 1000 vibrates in a direction perpendicular to the first sealing interface 410, the second seal 500 can be relied on to seal the gap between the outer frame 210 and the floor 300. When the vehicle body 1000 vibrates in a direction perpendicular to the second sealing interface 510, not only the first seal 400 can be relied on to seal the gap between the outer frame 210 and the floor 300, but also the third seal 600 can be relied on to seal the gap between the outer frame 210 and the main frame 100. This further reduces the risk of sealing failure between the outer frame 210 and the floor 300 and between the outer frame 210 and the main frame 100 due to vibration of the vehicle body 1000, and further improves the sealing performance of the battery 200.

[0153] In some embodiments of the present application, please refer to FIG. 7 and FIG. 8 , the outer frame 210 or the main frame 100 is provided with a third limiting groove 219 , and at least a portion of the third sealing member 600 is accommodated in the third limiting groove 219 .

[0154] In some embodiments, referring to FIG. 8 , the outer frame 210 is provided with a third limiting groove 219 . The third limiting groove 219 may be formed by a portion of the outer frame 210 facing the main frame 100 being recessed in a direction away from the main frame 100 .

[0155] In other embodiments, the main frame 100 is provided with a third limiting groove 219 . The third limiting groove 219 may be formed by a portion of the main frame 100 facing the outer frame 210 being recessed in a direction away from the outer frame 210 .

[0156] The third limiting groove 219 can be annular and arranged around the cavity 211 of the outer frame 210 . A portion of the third sealing member 600 is accommodated in the third limiting groove 219 , and another portion of the third sealing member 600 protrudes toward the outside of the third limiting groove 219 .

[0157] By adopting the above technical solution, the position of the third seal 600 is effectively limited to improve the situation where the third seal 600 is shifted when the vehicle body 1000 vibrates, thereby effectively reducing the risk of sealing failure between the outer frame 210 and the main frame 100 due to vibration of the vehicle body 1000, and further improving the sealing performance of the battery 200.

[0158] In some embodiments of the present application, please refer to Figures 3 to 8 together. The outer frame 210 includes a frame body 215 and a mounting base 216 connected to the frame body 215. The frame body 215 has a cavity 211. The mounting base 216 is installed on the main frame 100. A portion of the floor 300 cooperates with the frame body 215 to clamp the first seal 400 to form a first sealing interface 410. Another portion of the floor 300 cooperates with the frame body 215 to clamp the second seal 500 to form a second sealing interface 510. The main frame 100 cooperates with the mounting base 216 to clamp the third seal 600 to form a third sealing interface 610.

[0159] The frame 215 is the main body of the outer frame 210, and the mounting base 216 is a portion for connecting the frame 215 and the main frame 100. In some embodiments, the mounting base 216 is connected to the side of the frame 215 facing away from the cavity 211, and the mounting base 216 is annular and arranged around the frame 215. In some embodiments, the frame 215 and the mounting base 216 can be integrally formed components, for example, the frame 215 and the mounting base 216 are integrally formed using a die-casting process. In other embodiments, the frame 215 and the mounting base 216 are separately formed and then connected to each other to form a whole. The connection method between the frame 215 and the mounting base 216 can be, but is not limited to, welding, fastening connection, bonding, etc. The connection method between the mounting base 216 and the main frame 100 can be, but is not limited to, welding, fastening connection, bonding, etc.

[0160] By adopting the above technical solution, it is not only convenient to form the first sealing interface 410 and the second sealing interface 510 between the outer frame 210 and the floor 300 , but also convenient to form the third sealing interface 610 between the outer frame 210 and the main frame 100 .
