Description

Technical Field

[0001] This application relates to the field of battery technology, and more specifically, to a battery and a vehicle. Background Technology

[0002] In related technologies, the battery casing generally lacks mounting structures. When installing such batteries into a vehicle, the battery must first be placed into a battery swapping frame to house it, and then the swapping frame must be secured to the vehicle. The introduction of the swapping frame results in a larger required installation space. Given the limited space under the vehicle, this makes it difficult to increase the battery's volumetric energy density, thus affecting the vehicle's driving range. Furthermore, the batteries and swapping frames have poor compatibility; different vehicle models require matching different specifications of batteries and swapping frames, or necessitate the use of additional auxiliary components such as spacers for installation and adjustment, increasing assembly complexity, production costs, and subsequent maintenance costs. Summary of the Invention

[0003] This application provides a battery that can make full use of space to increase energy density, and the battery is highly versatile and can be matched with different vehicle models.

[0004] In a first aspect, embodiments of this application provide a battery, comprising: a battery body, the battery body including a battery cell and a housing for housing the battery cell, the housing defining a recess extending through both ends in a first direction, the battery being adapted to be disposed at the bottom of a vehicle, and a longitudinal beam of the vehicle floor being adapted to pass through the recess in the first direction; and a first mounting structure disposed on the bottom wall of the recess, the first mounting structure being used to detachably mount the battery body to the vehicle.

[0005] In the above technical solution, by setting a recess in the battery casing to avoid the longitudinal beam of the vehicle floor and a first mounting structure that can be detachably connected to the vehicle, the space on both sides of the longitudinal beam of the vehicle floor can be effectively utilized, and the battery swapping frame in related technologies can be eliminated. This is conducive to improving the energy density of the battery or increasing the battery's ground clearance, which is beneficial to the battery swapping design. Furthermore, by setting the first mounting structure on the bottom wall of the recess, the battery can be matched with different models of longitudinal beams of the vehicle floor, improving the battery's versatility and the convenience of disassembly and assembly, while also helping to reduce costs.

[0006] In some embodiments, the first mounting structure is at least partially located between two longitudinal beams of the vehicle underbody longitudinal beam. In the above technical solution, the first mounting structure can make full use of the space between the two longitudinal beams, reduce or avoid the first mounting structure occupying other space, thereby using the saved space to increase the energy density of the battery, and effectively avoid positional interference between the first mounting structure and the longitudinal beams.

[0007] In some embodiments, there are multiple first mounting structures, with at least two of the first mounting structures arranged at intervals along a second direction, the second direction intersecting the first direction. In the above technical solution, multiple second mounting structures can connect the battery to the vehicle from multiple points in the lateral direction of the vehicle, thereby improving the stability of the connection between the battery and the vehicle.

[0008] In some embodiments, the first mounting structure is disposed at both ends of the recess along the first direction. In the above technical solution, the first mounting structure is positioned relatively outward, which facilitates the assembly and disassembly of the first mounting structure from the vehicle, and minimizes the space occupied by the first mounting structure within the recess.

[0009] In some embodiments, at least one of the first mounting structures is provided along the edges of both ends of the recess in the first direction. In the above technical solution, connecting and fixing via the first mounting structures at both ends enables multi-point connection in the first direction, improving stability.

[0010] In some embodiments, the first mounting structure includes a mounting plate and a mounting portion mounted on the mounting plate, the mounting plate protruding from the bottom wall of the recess toward the longitudinal beam of the vehicle floor. In the above technical solution, the first mounting structure has a simple structure and high strength, and facilitates adjustment of the mounting position and orientation of the mounting portion.

[0011] In some embodiments, the mounting plate extends along a second direction and is provided with a plurality of mounting portions, the second direction intersecting the first direction. In the above technical solution, the plurality of mounting portions can be detachably connected to the vehicle to achieve battery installation and fixation from multiple points along the second direction, improving the stability of the battery installation on the vehicle; and the integration of the plurality of mounting portions into one mounting plate helps to improve the overall structural strength.

[0012] In some embodiments, the bottom wall of the recess is provided with a boss protruding toward the longitudinal beam of the vehicle floor. The mounting portion is located on the side of the mounting plate facing the boss and is used for detachable connection with a first connecting structure on the longitudinal beam of the vehicle floor. A gap is defined between the mounting plate and the boss to accommodate the first connecting structure. In the above technical solution, the mounting plate and the boss can play a certain limiting role for the first connecting structure, thereby improving the stability of the first connecting structure and the reliability of the connection between the first connecting structure and the mounting portion.

[0013] In some embodiments, the bottom wall of the recess is provided with a protruding boss facing the longitudinal beam of the vehicle floor. The first mounting structure is a mounting rib, one end of which is connected to the bottom wall of the recess and the other end is connected to the boss. In the above technical solution, the mounting rib is fixed and stable, eliminating the need for a separate structure for fixing the mounting rib, simplifying the structure on the battery and facilitating sealing at the recess. Furthermore, in embodiments including multiple mounting ribs, the multiple mounting ribs are independent of each other, and their structure and placement do not affect each other, making the number, structure, and position of the mounting ribs more flexible.

[0014] In some embodiments, the battery further includes a second mounting structure disposed outside the recess. In the above technical solution, the battery can be installed through structures both inside and outside the recess to improve stability, and the second mounting structure is less likely to be obstructed by the battery body, thereby facilitating the installation and removal of the second mounting structure from the vehicle.

[0015] Secondly, embodiments of this application also provide a vehicle, including a chassis longitudinal beam and the aforementioned battery, wherein the chassis longitudinal beam extends into the recess.

[0016] In the above technical solution, by setting a recess in the battery casing to avoid the longitudinal beam of the vehicle floor and a first mounting structure that can be detachably connected to the vehicle, the space on both sides of the longitudinal beam of the vehicle floor can be effectively utilized, and the battery swapping frame in related technologies can be eliminated. This is conducive to improving the energy density of the battery or increasing the battery's ground clearance, which is beneficial to the battery swapping design. Furthermore, by setting the first mounting structure on the bottom wall of the recess, the battery can be matched with different models of longitudinal beams of the vehicle floor, improving the battery's versatility and the convenience of disassembly and assembly, while also helping to reduce costs.

[0017] In some embodiments, the vehicle underbody longitudinal beam is provided with a first connecting structure for detachable connection with the first mounting structure, the first connecting structure being located between two longitudinal beams of the vehicle underbody longitudinal beam. In the above technical solution, the first connecting structure and its connection with the first mounting structure occupy the space between the two longitudinal beams, but do not occupy the height space between the vehicle underbody longitudinal beam and the battery. This allows for more space to house individual battery cells to increase energy density, or it facilitates increasing the battery's ground clearance to improve safety and ease of battery swapping.

[0018] In some embodiments, the first connecting structure includes a first mounting base and a plurality of first connecting portions mounted on the first mounting base. The first mounting base is mounted on the vehicle underbody longitudinal beam, and the first connecting portions are connected one-to-one with the first mounting structure. In the above technical solution, since the first connecting portions are not directly connected to the vehicle underbody longitudinal beam, only suitable first mounting bases need to be set for vehicle underbody longitudinal beams of different specifications, while the first connecting portions can adopt the same structure, size, and quantity, thereby improving the versatility of the first connecting portions and reducing production costs. In addition, the integration of multiple first connecting portions on the same first mounting base simplifies the installation on the vehicle underbody longitudinal beam and improves the overall strength of the first connecting structure.

[0019] In some embodiments, the first mounting base is connected to the two longitudinal beams at both ends. In the above technical solution, the first mounting base can be installed and fixed from both ends to improve stability; and the first mounting base can also serve as a connector, linking the two longitudinal beams together to improve the overall rigidity of the vehicle underbody longitudinal beams.

[0020] In some embodiments, the underbody longitudinal beam further includes a connecting beam connecting the two longitudinal beams, wherein the connecting beam and the first mounting seat are arranged along the first direction; or, the first mounting seat is mounted on the connecting beam. In the above technical solutions, the two longitudinal beams are connected by both the connecting beam and the first mounting seat, resulting in higher overall strength of the underbody longitudinal beam; or, mounting the first mounting seat on the connecting beam allows the size of the first mounting seat to be independent of the distance between the two longitudinal beams, thereby improving the versatility of the first mounting seat and reducing production costs.

[0021] In some embodiments, the first mounting base is telescopic along a second direction, which is the arrangement direction of the two longitudinal beams. In the above technical solution, by telescopically extending the first mounting base, it can be connected to two longitudinal beams with different spacings, thereby matching different vehicle models, improving the applicability of the first mounting base, and reducing production costs.

[0022] In some embodiments, the plurality of first connecting parts installed on the same first mounting base are all snap-fit ​​fasteners, and the plurality of snap-fit ​​fasteners are linked together by a linkage. In the above technical solution, the locking or unlocking of the entire first connecting structure can be completed by triggering the plurality of first connecting parts on the same first mounting base only once, which greatly improves the convenience of disassembly and assembly operations.

[0023] In some embodiments, the vehicle further includes two bracket bodies. The proximal ends of the two bracket bodies are respectively connected to two longitudinal beams of the vehicle floor longitudinal beam, and the distal ends are respectively provided with second connecting structures. The second connecting structures are used for detachable connection with the second mounting structure of the battery. In the above technical solution, the bracket bodies can indirectly install the second connecting structures to the vehicle floor longitudinal beam without changing the structure of the vehicle floor longitudinal beam itself. This facilitates the connection of the second connecting structures with the second mounting structures spaced apart along the second direction on the battery, which helps to reduce production costs.

[0024] In some embodiments, the second connection structure includes a second mounting base and a plurality of second connecting parts disposed on the second mounting base. The plurality of second connecting parts are arranged along the first direction and are connected one-to-one with the second mounting structure. In the above technical solution, since the second connecting parts are not directly connected to the bracket body, the second connecting parts can adopt the same structure, size and number for different bracket bodies, thereby improving the versatility of the second connecting parts and reducing production costs. In addition, the integration of multiple second connecting parts on the same second mounting base can simplify the installation on the vehicle underbody longitudinal beam and improve the overall strength of the second connection structure. The arrangement of multiple second connecting parts along the first direction can also realize multi-point installation and fixation of the battery in the first direction, improving the installation stability of the battery.

[0025] In some embodiments, the multiple second connecting parts installed on the same second mounting base are all snap-fit ​​fasteners, and the multiple snap-fit ​​fasteners are linked together by a linkage. In the above technical solution, the multiple second connecting parts on the same second mounting base only need to be triggered once to complete the locking or unlocking of the entire second connection structure, which greatly improves the convenience of disassembly and assembly operations.

[0039] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0040] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains; the terminology used in the description of this application is for the purpose of describing particular embodiments only and is not intended to limit the application; the terms "comprising" and "having," and any variations thereof, in the description, claims, and accompanying drawings of this application are intended to cover non-exclusive inclusion. The terms "first," "second," etc., in the description, claims, or accompanying drawings of this application are used to distinguish different objects, not to describe a specific order or hierarchy.

[0041] In this application, the reference to "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0042] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "attachment" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0043] In this application, the term "and / or" is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this application, the character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0044] In the embodiments of this application, the same reference numerals denote the same components, and for the sake of brevity, detailed descriptions of the same components are omitted in different embodiments. It should be understood that the thickness, length, width, and other dimensions of various components in the embodiments of this application shown in the accompanying drawings, as well as the overall thickness, length, width, and other dimensions of the integrated device, are merely illustrative and should not constitute any limitation on this application.

[0045] In this application, "multiple" means two or more (including two).

[0046] The battery mentioned in the embodiments of this application refers to a single physical module comprising one or more battery cells to provide higher voltage and capacity. The battery in the embodiments of this application includes a housing for encapsulating one or more battery cells or multiple battery modules. The housing can prevent liquids or other foreign matter from affecting the charging or discharging of the battery cells.

[0047] In a battery, multiple battery cells can be connected in series, parallel, or a combination thereof. A combination thereof means that multiple battery cells are connected in both series and parallel configurations. Multiple battery cells can be directly connected in series, parallel, or a combination thereof, and then the entire assembly of these cells is housed within a casing. Alternatively, a battery can consist of multiple battery cells first connected in series, parallel, or a combination thereof to form a battery module, and then these modules are connected in series, parallel, or a combination thereof to form a single unit housed within a casing. Furthermore, a battery can include other structures, such as a busbar component, for electrical connection between the multiple battery cells.

[0048] In recent years, new energy vehicles have experienced rapid development. In the field of electric vehicles, batteries, as the power source, play an irreplaceable and crucial role. As a core component of new energy vehicles, batteries have high requirements in terms of both safety and cycle life.

[0049] The inventors discovered that batteries are typically located at the bottom of vehicles, below the longitudinal beams. To improve driving range, given the limited width and length of the vehicle, the battery height must be maximized, resulting in a low ground clearance. This makes the battery susceptible to damage from bumps and knocks on uneven surfaces. Furthermore, during battery swapping, the swapping station needs pre-installed trenches or the vehicle needs to be raised, increasing swapping costs. Additionally, the battery casing generally lacks mounting structures. Installing such batteries into a vehicle requires first inserting the battery into a swapping frame, then securing the frame to the vehicle. The introduction of the swapping frame requires significant installation space, which, in the limited space under the vehicle, hinders the improvement of the battery's volumetric energy density, impacting driving range. Moreover, the specific structure of the swapping frame is limited by the structure of different vehicle models. For example, different longitudinal beams require different swapping frames, or additional components such as spacers are needed for installation and adjustment, complicating assembly and increasing production costs.

[0050] Based on this, the inventors, through in-depth research, designed a battery 1. The battery 1 has a recess 13 on its casing 12 to avoid the longitudinal beam 200 under the vehicle, and a first mounting structure 21 that can be detachably connected to the vehicle 1000. This can effectively utilize the space on both sides of the longitudinal beam 200 under the vehicle and eliminate the need for a battery swapping frame in related technologies. This is beneficial for increasing the energy density of the battery 1 or increasing the ground clearance of the battery 1, which is conducive to battery swapping design. Furthermore, by setting the first mounting structure 21 on the bottom wall of the recess 13, the battery 1 can be matched with different models of longitudinal beams 200 under the vehicle, improving the versatility of the battery 1 and the convenience of disassembly and assembly, while also helping to reduce costs.

[0051] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 1000 provided in some embodiments of this application. The vehicle 1000 can be a gasoline-powered vehicle, a natural gas-powered vehicle, or a new energy vehicle. New energy vehicles can be pure electric vehicles, hybrid electric vehicles, or range-extended electric vehicles, etc. The battery 1 can be used to power the vehicle 1000; for example, the battery 1 can serve as the operating power source for the vehicle 1000. The vehicle 1000 may also include a controller and a motor. The controller is used to control the battery 1 to supply power to the motor, for example, to meet the power needs of the vehicle 1000 during startup, navigation, and driving. In some embodiments of this application, the battery 1 can not only serve as the operating power source for the vehicle 1000 but also as the driving power source for the vehicle 1000, replacing or partially replacing gasoline or natural gas to provide driving power for the vehicle 1000.

[0052] Hereinafter, with reference to the accompanying drawings, a battery 1 according to an embodiment of the present application will be described.

[0053] like Figures 2-5 As shown, the battery 1 includes a battery body 10 and a first mounting structure 21. The battery body 10 includes a battery cell and a housing 12 for housing the battery cell. The housing 12 defines a recess 13 extending through both ends in a first direction F1. The battery 1 is adapted to be disposed at the bottom of a vehicle 1000, and a longitudinal beam 200 of the vehicle 1000 is adapted to pass through the recess 13 in the first direction F1. The first mounting structure 21 is disposed on the bottom wall of the recess 13, and the first mounting structure 21 is used to detachably mount the battery body 10 to the vehicle 1000.

[0054] In this article, "first direction F1" refers to the length direction of vehicle 1000, or the front-to-back direction of vehicle 1000, or the longitudinal direction of vehicle 1000; "second direction F2" refers to the width direction of vehicle 1000, or the left-to-right direction of vehicle 1000, or the lateral direction of vehicle 1000; and "third direction F3" refers to the height direction of vehicle 1000, or the up-down direction of vehicle 1000, or the vertical direction of vehicle 1000.

[0055] In the above embodiments, the number and arrangement of the battery cells housed in the housing 12 are not limited; there may be one or more. If there are multiple battery cells, they may be grouped together or set up individually.

[0056] It is worth noting that "the longitudinal beam 200 extends through the recess 13 along the first direction F1" means that at least a portion of the longitudinal beam 200 extends into the recess 13, not that the entire longitudinal beam 200 is located within the recess 13. More specifically, the longitudinal beam 200 may have a section extending into the recess 13 in the longitudinal direction, and further, this section may extend partially or entirely into the recess 13 in the vertical direction.

[0057] Because the top of the housing 12 has a recess 13 that is suitable for avoiding the longitudinal beam 200 of the vehicle floor, it is beneficial to ensure that the top wall of the battery cell housed in the housing 12 is higher than the bottom surface of the longitudinal beam 200. This allows for more effective use of the space on both sides of the longitudinal beam 200 to house the battery cells, increasing the energy density of the battery 1. Alternatively, battery cells that would normally be located at the bottom of the battery 1 can be moved to the sides of the longitudinal beam 200, thereby increasing the ground clearance of the battery 1. This ensures sufficient space between the bottom of the battery 1 and the ground for battery swapping operations. Furthermore, the increased ground clearance reduces the risk of damage or scratches to the bottom of the battery 1 due to ground protrusions, improving the safety and lifespan of the battery 1. Therefore, by providing a recess 13 on the top of the housing 12, the problem of low space utilization can be effectively solved, which is beneficial to improving the safety and reliability of the battery 1 and facilitating battery swapping design. In addition, the irregular structure design of the housing 12 with the recess 13 can improve the structural strength of the housing 12 and enhance the stability of the battery 1.

[0058] In the above embodiments, the manner in which the first mounting structure 21 is disposed on the housing 12 is not limited. It can be an integral part of the housing 12, or it can be a separate part of the housing 12 and directly or indirectly installed on the housing 12. In the above embodiments, since the first mounting structure 21 detachably installs the battery body 10 to the longitudinal beam 200 under the vehicle, the battery 1 is detachable relative to the vehicle 1000, thereby meeting the needs of battery 1 replacement, charging, maintenance, etc.

[0059] In addition, it should be noted that the connection method between the first mounting structure 21 and the vehicle 1000 is not limited. It can be directly connected to the part of the vehicle bottom longitudinal beam 200 facing the first mounting structure 21, or it can be indirectly connected to the connection structure set on the vehicle bottom longitudinal beam 200 facing the first mounting structure 21.

[0060] This application provides a first mounting structure 21 on the casing 12 of the battery 1, which can be detachably connected to the vehicle 1000. This allows the battery 1 to be mounted to the vehicle 1000 using the first mounting structure 21, eliminating the need for a battery swapping frame used in related technologies. This reduces the space occupied by the battery swapping frame, thereby increasing the volumetric energy density of the battery 1. Furthermore, eliminating the battery swapping frame reduces costs, lowers the overall vehicle load, and improves battery swapping efficiency. Moreover, it reduces the design requirements for the battery swapping transport vehicle in terms of battery size and load-bearing capacity, lowering the design difficulty and cost of the transport vehicle.

[0061] Furthermore, by eliminating the battery swapping frame, the ground clearance of battery 1 is increased, reducing the risk of damage to battery 1 due to ground protrusions and improving its safety and lifespan. Increasing the ground clearance of battery 1 also facilitates battery swapping operations. In some cases, the battery swapping station 2000 can be used without digging a trench or raising vehicle 1000. In short, it eliminates the need for vehicle lifting or trench digging, simplifying the layout of the battery swapping station 2000 and improving space utilization.

[0062] Furthermore, "the first mounting structure 21 is disposed on the bottom wall of the recess 13." The bottom wall refers to the wall surface of the recess 13 located below the longitudinal beam 200 of the vehicle floor. It can correspond to the area directly below the two longitudinal beams 201 of the vehicle floor longitudinal beam 200, the area between the two longitudinal beams 201, or the areas on both sides directly below the two longitudinal beams 201. For example, the recess 13 may include a bottom wall and two side walls. The bottom wall is perpendicular to the third direction F3, and the side walls are perpendicular to the second direction F2. The two side walls are arranged opposite each other along the second direction F2 and are respectively connected to the two end edges of the bottom wall. The first mounting structure 21 is disposed on the bottom wall of the recess 13, that is, the first mounting structure 21 is generally disposed in the middle of the battery 1 along the second direction F2, and is not disposed on the side wall of the recess 13. Therefore, the first mounting structure 21 is not limited by the size of the longitudinal beam 200 of the vehicle floor along the second direction F2.

[0063] For example, the width of the underbody longitudinal beam 200 along the second direction F2 can be different for different models of vehicle 1000; for a battery 1 of a certain specification, the size of the recess 13 along the second direction F2 is fixed. If the first mounting structure 21 is located on the side wall of the recess 13, when connected to the vehicle 1000, the distance between the underbody longitudinal beam 200 of different widths and the side wall of the recess 13 is different, thus the distance between the first mounting structure 21 and the side wall is different. It is necessary to replace the pads of different thicknesses or numbers to fill the gap so that the first mounting structure 21 can be connected to the underbody longitudinal beam 200 of different widths.

[0064] This application uses a first mounting structure 21 located on the bottom wall of the recess 13, so that when the battery 1 is matched with the longitudinal beams 200 of different widths, the connection between the first mounting structure 21 and the vehicle 1000 will not be affected. The battery 1 can be moved to the appropriate position along the first direction F1 so that the first mounting structure 21 can be smoothly connected to the vehicle 1000 without the need for auxiliary mounting structures such as pads. Alternatively, different vehicle models can use auxiliary mounting structures such as pads of the same size. For example, the battery swapping station 2000 can be equipped with only one type of battery 1 to meet the battery swapping needs of different vehicle models.

[0065] Therefore, on the one hand, the versatility of battery 1 is improved, and the same battery 1 can meet the needs of different vehicle models; on the other hand, there is no need to set up auxiliary components or frequently adjust auxiliary components, making the installation and removal of battery 1 more convenient and efficient, which is conducive to improving battery swapping efficiency and reducing production and battery swapping costs.

[0066] According to the embodiments of this application, the battery 1 has a recess 13 on its housing 12 to avoid the longitudinal beam 200 of the vehicle floor, and a first mounting structure 21 that can be detachably connected to the vehicle 1000. This can effectively utilize the space on both sides of the longitudinal beam 200 of the vehicle floor and eliminate the need for a battery swapping frame in related technologies. This is beneficial for increasing the energy density of the battery 1 or increasing the ground clearance of the battery 1, which is beneficial for battery swapping design. Furthermore, the first mounting structure 21 is located on the bottom wall of the recess 13, which allows the battery 1 to be matched with different models of longitudinal beams 200 of the vehicle floor, improving the versatility of the battery 1 and the convenience of disassembly and assembly, while also helping to reduce costs.

[0067] In the above embodiments, the position of the first mounting structure 21 relative to the two longitudinal beams 201 can be flexibly set. For example, the position of the first mounting structure 21 can correspond to directly below the two longitudinal beams 201 of the vehicle undercarriage longitudinal beam 200, between the two longitudinal beams 201 directly below each other, or on both sides directly below the two longitudinal beams 201.

[0068] In some embodiments, such as Figures 2-5 As shown, the first mounting structure 21 is at least partially located between the two longitudinal beams 201 of the vehicle undercarriage longitudinal beam 200. That is, the first mounting structure 21 is positioned partially or entirely between the two longitudinal beams 201 directly below each other. In the third direction F3, the top of the first mounting structure 21 is higher than the bottom of the two longitudinal beams 201, and the bottom of the first mounting structure 21 is lower than or flush with the bottom of the two longitudinal beams 201, so that at least a portion of the first mounting structure 21 can occupy the space between the two longitudinal beams 201.

[0069] Therefore, the first mounting structure 21 can make full use of the space between the two longitudinal beams 201, reducing or avoiding the first mounting structure 21 occupying other space, and thus the energy density of the battery 1 can be increased by using the saved space. Moreover, for the vehicle underbody longitudinal beams 200 with arbitrary width in the second direction F2, the first mounting structure 21 will not interfere with the position of the two longitudinal beams 201, ensuring that the battery 1 can be adapted to different vehicle models and improving the versatility of the battery 1.

[0070] According to some embodiments of this application, such as Figures 2-5 As shown, there are multiple first mounting structures 21, with at least two first mounting structures 21 arranged at intervals along the second direction F2, and the second direction F2 intersecting the first direction F1. Here, "intersecting" includes, but is not limited to, an angle of 90° between the first direction F1 and the second direction F2. By arranging two or more first mounting structures 21 at intervals along the second direction F2, multiple second mounting structures 22 can connect the battery 1 to the vehicle 1000 from multiple points in the lateral direction of the vehicle 1000, thereby improving the stability of the connection between the battery 1 and the vehicle 1000.

[0071] It should be noted that the multiple first mounting structures 21 can be arranged in a row along the second direction F2; the multiple first mounting structures 21 can also be arranged in multiple rows spaced apart along the first direction F1, with each row including at least two first mounting structures 21. Thus, multiple points of connection can be formed from both the first direction F1 and the second direction F2, further improving stability.

[0072] In some embodiments, such as Figures 2-5 As shown, the first mounting structure 21 is located at both ends of the recess 13 along the first direction F1. That is, in the first direction F1, the first mounting structure 21 is located near the end of the battery 1, such as at the front and rear edges of the recess 13. On the one hand, this makes the first mounting structure 21 relatively outward, reducing the obstruction of the first mounting structure 21 by the battery 1, thereby facilitating the installation and removal of the first mounting structure 21 from the vehicle 1000; on the other hand, it minimizes the space occupied by the first mounting structure 21 within the recess 13, avoiding interference with other structures within the recess 13 (such as docking structures), resulting in a more reasonable positional arrangement.

[0073] In this embodiment, the first mounting structure 21 can be provided at one end of the edge of the recess 13 along the first direction F1 to simplify the structure; alternatively, the first mounting structure 21 can be provided at both ends to achieve better connection stability. For example, in some specific embodiments, continue to refer to... Figures 2-5 As shown, the recess 13 has at least one first mounting structure 21 at each end of the first direction F1. By connecting and fixing with the first mounting structures 21 at both ends, multi-point connections in the first direction F1 can be achieved, improving stability. Furthermore, in embodiments where multiple first mounting structures 21 are provided at each end, multi-point connections in the first direction F1 and the second direction F2 can be achieved, thus limiting movement in both directions and improving stability.

[0074] In the embodiments of this application, the specific structure of the first mounting structure 21 can be flexibly set according to actual needs. For example, the first mounting structure 21 can be a locking pin, a buckle, a bolt, a nut, etc.

[0075] For example, in some embodiments, such as Figure 2 and Figure 3As shown, the first mounting structure 21 includes a mounting plate 211 and a mounting portion 212 mounted on the mounting plate 211. The mounting plate 211 protrudes from the bottom wall of the recess 13 toward the longitudinal beam 200 of the vehicle floor, that is, the mounting plate 211 protrudes upward from the bottom wall of the recess 13. The mounting portion 212 can be used to connect with the vehicle 1000 and can be a lock hole, lock pin, bolt, nut, buckle, etc. By cooperating with the mounting plate 211 and the mounting portion 212, the overall structural strength of the first mounting structure 21 can be improved, and the setting position and orientation of the mounting portion 212 can be easily adjusted. For example, the mounting portion 212 can be located at the upper end of the mounting plate 211 to increase the height, or the mounting portion 212 can be located on one side of the mounting plate 211 in the thickness direction to change the orientation.

[0076] In some embodiments where the battery 1 is connected to the vehicle 1 at more than 1,000 points, there can be multiple mounting plates 211, each mounting plate 211 having a mounting part 212. The multiple mounting plates 211 and the corresponding mounting parts 212 are flexibly positioned, which is beneficial for reducing weight. Alternatively, there can be at least one mounting plate 211, each mounting plate 211 having multiple mounting parts 212. The multiple mounting parts 212 are integrated, the structure is simple and easy to manufacture, and the overall structural strength of the mounting plate 211 is higher.

[0077] In some specific embodiments, such as Figure 2 and Figure 3 As shown, the mounting plate 211 extends along the second direction F2 and is provided with multiple mounting portions 212. Each mounting portion 212 can be detachably connected to the vehicle 1000 to secure the battery 1 from multiple points along the second direction F2, thereby improving the stability of the battery 1 installed on the vehicle 1000. Furthermore, the integration of multiple mounting portions 212 into a single mounting plate 211 helps to improve the overall structural strength.

[0078] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, the bottom wall of the recess 13 has a boss 14 protruding toward the longitudinal beam 200 of the vehicle floor. A mounting part 212 is provided on the side of the mounting plate 211 facing the boss 14, and the mounting part 212 is used for detachable connection with the first connecting structure 31 on the longitudinal beam 200 of the vehicle floor. A gap is defined between the mounting plate 211 and the boss 14 to accommodate the first connecting structure 31.

[0079] The boss 14 can be formed by deforming the bottom wall of the recess 13, or the boss 14 can be a protrusion structure installed on the bottom wall of the recess 13. In some embodiments, the boss 14 can be used to install components such as docking structures, which are used to dock with the vehicle 1000 to achieve current conduction or liquid conduction.

[0080] In the above embodiments, the first connecting structure 31 can be integral with the vehicle underbody longitudinal beam 200, or it can be a separate component and directly or indirectly installed to the vehicle underbody longitudinal beam 200. By extending the first connecting structure 31 into the gap between the boss 14 and the mounting plate 211, it facilitates the connection between the first connecting structure 31 and the mounting part 212. Furthermore, the mounting plate 211 and the boss 14 can provide a certain degree of restraint for the first connecting structure 31, thereby improving the stability of the first connecting structure 31 and the reliability of the connection between the first connecting structure 31 and the mounting part 212.

[0081] For example, in such Figure 2 and Figure 3 In the example shown, the first connecting structure 31 is generally a plate that extends between the mounting plate 211 and the boss 14. The two side surfaces of the plate are respectively fitted with the side surfaces of the mounting plate 211 and the boss 14 to achieve positioning.

[0082] According to other embodiments of this application, such as Figure 4 and Figure 5 As shown, the bottom wall of the recess 13 is provided with a boss 14 protruding towards the longitudinal beam 200 of the vehicle bottom. The first mounting structure 21 is a mounting rib 213, one end of which is connected to the bottom wall of the recess 13, and the other end of which is connected to the boss 14.

[0083] From one end of the mounting rib 213 to the other, the mounting rib 213 can extend along any shape such as a zigzag or an arc, as long as it meets the requirement of being able to connect with the bottom wall of the recess 13 and the boss 14. For example Figure 4 The mounting rib 213 shown is an L-shaped rib, with one rib extending along the first direction F1 and the other extending along the third direction F3. Furthermore, the other end of the mounting rib 213 can be connected to the side or top surface of the boss 14.

[0084] By connecting the two ends of the mounting rib 213 to the bottom wall of the recess 13 and the boss 14 respectively, the mounting rib 213 is fixed and stable, eliminating the need for a separate structure for fixing the mounting rib 213 and simplifying the structure on the battery 1. On the other hand, in embodiments that include multiple mounting ribs 213, the multiple mounting ribs 213 are independent of each other, and their structure and setting position do not affect each other, making the number, structure and position adjustment of the mounting ribs 213 more flexible.

[0085] According to some embodiments of this application, such as Figures 2-5 As shown, the battery 1 also includes a second mounting structure 22, which is disposed outside the recess 13.

[0086] In the above embodiments, the second mounting structure 22 may be the same as or different from the first mounting structure 21. The second mounting structure 22 may be a bolt, nut, buckle, locking pin or other structure.

[0087] The location of the second mounting structure 22 outside the recess 13 is not limited. For example, it can be located on the end walls of the casing 12 of the battery 1 at both ends along the first direction F1, at both ends along the second direction F2, or at both ends along the third direction F3.

[0088] By providing a second mounting structure 22 for connection with the vehicle 1000 outside the recess 13, the battery 1 can be installed through structures both inside and outside the recess 13, improving stability. Furthermore, the second mounting structure 22 is less likely to be obstructed by the battery body 10, thus facilitating the installation and removal of the second mounting structure 22 from the vehicle 1000. For example, the second mounting structure 22 and the vehicle 1000 can use a low-cost locking and unlocking method such as snap-fit, facilitating installation and removal while reducing production costs.

[0089] In some embodiments, such as Figures 2-5 As shown, at least two second mounting structures 22 are respectively disposed on the end walls of the housing 12 at both ends along the second direction F2, where the first direction F1 and the second direction F2 intersect. The second mounting structures 22 located at both ends of the housing 12 can install and fix the housing 12 to the maximum extent from the second direction F2, which is more conducive to improving installation stability; and, since the second mounting structures 22 disposed on the end walls of the housing 12 are completely exposed, during the disassembly and assembly of the battery 1, the connection of the second mounting structures 22 can be operated from the side to achieve locking and unlocking, which greatly improves the convenience of operation.

[0090] In some specific embodiments, the end wall of the housing 12 at the same end along the second direction F2 may be provided with multiple second mounting structures 22, and these multiple second mounting structures 22 are arranged at intervals along the first direction F1 to achieve multi-point connection and fixation from the first direction F1. Thus, the first mounting structure 21 and the second mounting structure 22 cooperate to achieve multi-point installation in the second direction F2, and the multiple second mounting structures 22 achieve multi-point installation in the first direction F1. The two methods work together to achieve a more stable battery 1 installation effect.

[0091] like Figures 1-5 As shown, the vehicle 1000 according to an embodiment of this application includes a chassis longitudinal beam 200 and a battery 1 according to an embodiment of this application, with the chassis longitudinal beam 200 extending into the recess 13.

[0092] Since the battery 1 according to the embodiments of this application has the above-mentioned beneficial technical effects, the vehicle 1000 according to the embodiments of this application, by providing a recess 13 for avoiding the vehicle under-floor longitudinal beam 200 and a first mounting structure 21 that can be detachably connected to the vehicle 1000 in the housing 12 of the battery 1, can effectively utilize the space on both sides of the vehicle under-floor longitudinal beam 200 and eliminate the need for the battery swapping frame in related technologies, thereby improving the energy density of the battery 1 or increasing the ground clearance of the battery 1, which is beneficial to the battery swapping design; and by providing the first mounting structure 21 on the bottom wall of the recess 13, the battery 1 can be matched with different models of vehicle under-floor longitudinal beams 200, improving the versatility of the battery 1 and the convenience of disassembly and assembly, while also helping to reduce costs.

[0093] In some embodiments of this application, such as Figures 2-5 As shown, the vehicle bottom longitudinal beam 200 is provided with a first connecting structure 31 for detachable connection with the first mounting structure 21. The first connecting structure 31 is located between the two longitudinal beams 201 of the vehicle bottom longitudinal beam 200.

[0094] The manner in which the first connecting structure 31 is disposed on the longitudinal beam 200 of the vehicle floor is not limited. It can be an integral part of the longitudinal beam 200 of the vehicle floor, or it can be a separate part of the longitudinal beam 200 of the vehicle floor and be directly or indirectly installed to the longitudinal beam 200 of the vehicle floor. For example, the first connecting structure 31 and the longitudinal beam 200 of the vehicle floor can be welded together. The specific structure of the first connecting structure 31 is not limited, and it can be a buckle, bolt, nut, locking shaft, etc.

[0095] The first connecting structure 31 is located between the two longitudinal beams 201 of the vehicle under longitudinal beam 200. After the first connecting structure 31 is connected to the first mounting structure 21, the connection point is also located between the two longitudinal beams 201, so that the first connecting structure 31 and the connection point with the first mounting structure 21 occupy the space between the two longitudinal beams 201, but do not occupy the height space between the vehicle under longitudinal beam 200 and the battery 1. This allows the battery 1 to have more space to install battery cells to improve energy density, or it is beneficial to increase the ground clearance of the battery 1 to improve safety and the convenience of battery swapping operation.

[0096] In some embodiments, such as Figures 2-5 As shown, the first connecting structure 31 includes a first mounting base 311 and a plurality of first connecting parts 312 mounted on the first mounting base 311. The first mounting base 311 is mounted on the longitudinal beam 200 of the vehicle floor, and the first connecting parts 312 are connected to the first mounting structure 21 in a one-to-one correspondence.

[0097] The first mounting base 311 is used to install and fix the first connecting structure 31 on the longitudinal beam 200 of the vehicle bottom, and to provide support for the first connecting part 312. The first connecting part 312 can be a structure such as a buckle, bolt, nut, or locking shaft, for detachable connection with the first mounting structure 21.

[0098] Since the first connecting part 312 is not directly connected to the longitudinal beam 200 of the vehicle floor, only a suitable first mounting base 311 needs to be provided for longitudinal beams 200 of different specifications. The first connecting parts 312 can adopt the same structure, size and quantity, thereby improving the versatility of the first connecting parts 312 and reducing production costs. In addition, the integration of multiple first connecting parts 312 into the same first mounting base 311 can simplify the installation on the longitudinal beam 200 of the vehicle floor and improve the overall strength of the first connecting structure 31.

[0099] In some embodiments, such as Figures 2-5 As shown, the two ends of the first mounting base 311 can be connected to the two longitudinal beams 201 respectively. For example, each of the two longitudinal beams 201 has a groove 202 on its opposite side, and the end of the first mounting base 311 can extend into the groove 202. On the one hand, the first mounting base 311 can be installed and fixed from both ends to improve stability; on the other hand, the first mounting base 311 can serve as a connector, connecting the two longitudinal beams 201 into one piece to improve the overall rigidity of the vehicle underbody longitudinal beam 200.

[0100] It should be noted that in the above embodiments, there is no need to provide an additional connecting beam between the two longitudinal beams 201 to simplify the structure and reduce costs; or, a connecting beam may be provided between the two longitudinal beams 201 to connect the two longitudinal beams 201, so as to further improve the overall rigidity of the underbody longitudinal beam 200.

[0101] In some specific embodiments, the underbody longitudinal beam 200 includes a connecting beam that connects two longitudinal beams 201. The connecting beam and the first mounting base 311 are arranged along a first direction F1. In other words, the first mounting base 311 is connected to the longitudinal beam 201 but not directly to the connecting beam. The two longitudinal beams 201 are connected through both the connecting beam and the first mounting base 311, resulting in higher overall strength for the underbody longitudinal beam 200.

[0102] Alternatively, in some embodiments, the first mounting base 311 can be mounted on the connecting beam to achieve an indirect connection between the first mounting base 311 and the longitudinal beam 201. This also enables the first connecting structure 31 to be mounted and fixed on the longitudinal beam 200 of the vehicle floor, and the size of the first mounting base 311 is not affected by the distance between the two longitudinal beams 201. That is, for longitudinal beams 200 of different widths, the same first mounting base 311 can be used to improve the versatility of the first mounting base 311 and reduce production costs.

[0103] According to some embodiments of this application, the first mounting base 311 is telescopic along a second direction F2, where the second direction F2 is the arrangement direction of the two longitudinal beams 201. For example, the first mounting base 311 may include two base sections, which are movably connected together along the second direction F2.

[0104] Therefore, by extending and retracting the first mounting base 311, the first mounting base 311 can be connected to two longitudinal beams 201 with different spacing, thereby matching different models of vehicles 1000, improving the applicability of the first mounting base 311 and reducing production costs.

[0105] In some embodiments, such as Figures 2-5 As shown, the multiple first connecting parts 312 installed on the same first mounting base 311 are all snap-fit, and the multiple snap-fit ​​are linked together by the connecting rod 33.

[0106] When one of the latches is triggered to engage with the corresponding first mounting structure 21, the connecting rod 33 can drive the connected latch to achieve engagement; when one of the latches is triggered to disengage from the corresponding first mounting structure 21, the connecting rod 33 can drive the connected latch to disengage.

[0107] Therefore, multiple first connecting parts 312 of the same first mounting base 311 can complete the locking or unlocking of the entire first connecting structure 31 with just one trigger, greatly improving the convenience of disassembly and assembly operations; and during the installation process, only one of the first connecting parts 312 needs to be placed in an easy-to-operate position, and the disassembly and assembly operations of the other first connecting parts 312 are not affected by the setting position, so that a part of the first connecting structure 31 can be placed in an area that is not easy to operate, so as to achieve a better installation and fixing effect, such as being located in the recess 13 of the battery 1 or in a position covered by the battery body 10.

[0108] According to some embodiments of this application, such as Figures 2-5 As shown, the vehicle 1000 also includes two bracket bodies 40. The ends of the two bracket bodies 40 that are close to each other are respectively connected to the two longitudinal beams 201 of the vehicle bottom longitudinal beam 200, and the ends of the two bracket bodies 40 that are far from each other are respectively provided with a second connecting structure 32. The second connecting structure 32 is used to detachably connect to the second mounting structure 22 of the battery 1.

[0109] The bracket body 40 allows the second connecting structure 32 to be indirectly installed on the longitudinal beam 200 of the vehicle floor without altering its own structure. This facilitates the connection between the second connecting structure 32 and the second mounting structures 22 spaced along the second direction F2 on the battery 1, reducing production costs. Simultaneously, it avoids installing the second connecting structure 32 directly onto the vehicle body 1000, preventing any impact on the vehicle's structure. Furthermore, by setting up the bracket body 40, the structural strength of the longitudinal beam 200 and the battery 1 is improved, and the second connecting structure 32 and the second mounting structure 22 are located in a more easily accessible area, facilitating the installation and removal of the battery 1.

[0110] It should be noted that the ends of the two bracket bodies 40 that are close to each other can be completely located outside the recess 13 of the battery 1, and the upper part of the vehicle bottom longitudinal beam 200 is located outside the recess 13 and connected to the bracket body 40, so as to avoid occupying the space inside the recess 13, and the bracket body 40 is simpler; or the ends of the two bracket bodies 40 that are close to each other can extend into the recess 13 and be connected to the vehicle bottom longitudinal beam 200 located in the recess 13, so as to improve the structural strength of the bracket body 40 and the connection strength between the bracket body 40 and the vehicle bottom longitudinal beam 200; or, the ends of the two bracket bodies 40 that are close to each other can be connected together to further improve the overall structural strength.

[0111] In some embodiments, such as Figures 2-5 As shown, the bracket body 40 can be generally L-shaped and includes a first frame 41 and a second frame 42. The first frame 41 is located on the upper side of the battery 1, and the second frame 42 is located on the outer side of the battery 1 along the second direction F2. One end of the first frame 41 in the second direction F2 is connected to the longitudinal beam 200 under the vehicle floor, and the other end is connected to the upper end of the second frame 42. The lower end of the second frame 42 is provided with a second connecting structure 32. The first frame 41 and the second frame 42 can be assembled from rods, or they can be plate structures, or they can be plates with holes, etc. The bracket body 40 occupies relatively little space in both the second direction F2 and the third direction F3, which is beneficial for improving the energy density and ground clearance of the battery 1, and also helps to reduce the weight of the bracket body 40.

[0112] It should be noted that in the embodiment where multiple batteries 1 are installed on the vehicle 1000, each battery 1 can be provided with two bracket bodies 40 respectively. In other words, the multiple bracket bodies 40 are independent of each other, and their structures and installation positions do not affect each other, which facilitates structural arrangement and also helps to reduce weight.

[0113] In some embodiments, continue to refer to Figures 2-5 As shown, the second connection structure 32 includes a second mounting base 321 and a plurality of second connection parts 322 disposed on the second mounting base 321. The plurality of second connection parts 322 are arranged along the first direction F1 and are connected to the second mounting structure 22 one by one.

[0114] The second mounting base 321 is used to install and fix the second connecting structure 32 on the bracket body 40, and to provide support for the second connecting part 322. The second connecting part 322 can be a structure such as a snap fastener, bolt, nut, or locking shaft, for detachable connection with the second mounting structure 22.

[0115] Since the second connecting part 322 is not directly connected to the bracket body 40, a second mounting base 321 of appropriate size or the same specification can be selected for different bracket bodies 40 (such as bracket bodies 40 with different extension dimensions in the first direction F1). Furthermore, the second connecting parts 322 can adopt the same structure, size, and quantity, thereby improving the versatility of the second connecting parts 322 and reducing production costs. In addition, integrating multiple second connecting parts 322 into the same second mounting base 321 simplifies installation on the vehicle underbody longitudinal beam 200 and improves the overall strength of the second connecting structure 32. The arrangement of multiple second connecting parts 322 along the first direction F1 also enables multi-point mounting and fixing of the battery 1 in the first direction F1, improving the installation stability of the battery 1.

[0116] In some embodiments, the end walls of the battery 1 housing 12 along both ends of the second direction F2 are provided with mounting grooves 121. The mounting grooves 121 open at their outer ends along the second direction F2 and at their upper ends along the third direction F3. The second mounting structure 22 is located within the mounting grooves 121, and the second connecting structure 32 is adapted to extend into the mounting grooves 121 and connect with the second mounting structure 22. Thus, the groove walls of the mounting grooves 121 can, to a certain extent, shield the second mounting structure 22 and the second connecting structure 32, preventing water, mud, etc., from splashing and contaminating the second connecting structure 32 and the second mounting structure 22 during vehicle 1000 operation. Furthermore, the second connecting structure 32 can be easily installed and removed from the second mounting structure 22 through the openings of the mounting grooves 121, ensuring convenient operation.

[0117] In some embodiments, such as Figure 2 and Figure 4 As shown, the multiple second connecting parts 322 installed on the same second mounting base 321 are all snap-fit, and the multiple snap-fits are linked together by the connecting rod 33.

[0118] When one of the latches is triggered to engage with the corresponding second mounting structure 22, the connecting rod 33 can drive the connected latch to achieve engagement; when one of the latches is triggered to disengage from the corresponding second mounting structure 22, the connecting rod 33 can drive the connected latch to disengage.

[0119] Therefore, multiple second connecting parts 322 of the same second mounting base 321 can complete the locking or unlocking of the entire second connecting structure 32 with just one trigger, greatly improving the convenience of disassembly and assembly operations; and during the installation process, only one of the second connecting parts 322 needs to be set in an easy-to-operate position, and the disassembly and assembly operations of the other second connecting parts 322 are not affected by the setting position, so that a part of the second connecting structure 32 can be set in an area that is not easy to operate, so as to achieve a better installation and fixing effect.

[0120] Hereinafter, with reference to the accompanying drawings, a battery swapping station 2000 according to an embodiment of this application will be described.

[0121] like Figure 6 As shown, the battery swapping station 2000 is used to replace the battery 1 of the vehicle 1000 according to any embodiment of this application.

[0122] In some embodiments, the battery swapping station 2000 includes a battery swapping area 600, and the vehicle 1000 is adapted to swap the battery 1 in the battery swapping area 600. The battery swapping area 600 includes a first area 601 and a second area 602. The first area 601 is adapted to be located directly below the battery 1, and the second area 602 is used to support the front wheel and the rear wheel adjacent to the battery 1. The first area 601 and the second area 602 are flush with the ground.

[0123] Since the bottom surface of the battery 1 can be raised above the ground according to some embodiments of this application, the battery swapping station 2000 can eliminate the need for lifting the entire vehicle or digging trenches, thereby simplifying the site layout of the battery swapping station 2000 and improving space utilization.

[0124] Optionally, the ground of the battery swapping area 600 is entirely flat, which reduces the construction difficulty of the battery swapping station 2000 and helps to reduce the construction cost of the battery swapping station 2000.

[0125] The following description, in conjunction with the accompanying drawings, describes a specific embodiment of a battery 1 and a vehicle 1000 having the same.

[0126] The vehicle 1000 includes a chassis longitudinal beam 200 and a battery body 10. The chassis longitudinal beam 200 includes two longitudinal beams 201 extending along a first direction F1 and arranged along a second direction F2. The battery body 10 is detachably mounted to the chassis longitudinal beam 200 via a locking assembly. The locking assembly includes a detachably connected first connecting structure 31 and a first mounting structure 21, and a detachably connected second connecting structure 32 and a second mounting structure 22. This allows for battery swapping using the chassis of the two longitudinal beams 201 of the vehicle 1000, and the center of gravity of the battery body 10 is located below the longitudinal beams 201, effectively lowering the center of gravity of the battery body 10, increasing the stability of the battery body 10, and significantly improving the stability and safety of the vehicle 1000. It also has advantages such as a compact structure and high space utilization (especially in the vertical direction).

[0127] In related technologies, the battery needs to be pre-installed on the battery swapping frame before the entire frame is fixed to the vehicle. Because the battery is pre-installed on the frame, the entire swapping unit is large and heavy, requiring a larger and heavier AGV for the swapping system, thus complicating the design. Secondly, because the battery is integrated, more swapping frames are needed to withstand the stress, increasing the space occupied by the frames and limiting the battery capacity of the system, thus restricting the distance between swapping stations. Thirdly, because the batteries are integrated as a single swapping unit, the locking points have a large span, resulting in significant deviations between them. This increases locking time and reduces the success rate, greatly hindering swapping efficiency. Finally, because the battery is integrated as a single unit, each vehicle model can only use one type of battery, and different application scenarios can only use a single battery, resulting in low flexibility and poor product compatibility.

[0128] In this application, each battery body 10 is individually mounted to the longitudinal beam 200 under the vehicle via the first mounting structure 21 and the second mounting structure 22, reducing the space occupied by the battery swapping frame, effectively solving the problem of low space utilization and improving the energy density of the battery swapping system. Because it is a sub-package system, different numbers of battery bodies 10 can be matched to different application scenarios and vehicle models. Furthermore, the sub-package further reduces the size of the battery body 10, thereby reducing the span between mounting structures and improving the spacing accuracy of the mounting structures, thus effectively improving the locking success rate. Moreover, the first mounting structure 21 and the first connecting structure 31, and the second mounting structure 22 and the second connecting structure 32, use a snap-fit ​​mechanism, which greatly improves the battery swapping efficiency. Due to the sub-package system, the volume of the battery body 10 is significantly reduced compared to previous solutions, thus providing a better solution for both the design of the battery swapping AGV and the design of the battery swapping station 2000.

[0129] Furthermore, the first mounting structure 21 is arranged within the recess 13 of the battery body 10, and the second mounting structure 22 is arranged at both ends of the battery body 10 along the second direction F2, which can improve the strength of the installation between the battery body 10 and the longitudinal beam 200 of the vehicle floor. Moreover, the multiple first mounting structures 21 within the recess 13 are located on the bottom wall of the recess 13, which can improve the compatibility of the battery 1 and avoid strength loss caused by adding pads at the locking position. Furthermore, since the multiple second mounting structures 22 are spaced apart along the first direction F1 and the multiple first mounting structures 21 are spaced apart along the second direction F2, the battery 1 is further positioned, reducing battery 1 shaking and improving strength. In addition, the size of the battery body 10 along the second direction F2 is larger than its size along the first direction F1, thus reducing the span between the multiple mounting structures and improving locking accuracy and efficiency.

[0130] In addition, the first mounting structure 21 located in the recess 13 is arranged along the second direction F2. Its maximum span meets the dimensions between the two longitudinal beams 201 of the minimum vehicle bottom longitudinal beam 200. The dimensions of the recess 13 along the second direction F2 meet the dimensions of the outer sides of the two longitudinal beams 201. Therefore, when the battery 1 is installed on different vehicle bottom longitudinal beams 200, it is only necessary to change the first mounting seat 311 of the first connecting structure 31 on the vehicle bottom longitudinal beam 200. It is not necessary to replace different pads to achieve this, thereby improving the consistency of the battery 1. As a result, the same battery 1 can meet the use of different vehicle bottom longitudinal beams 200, and the structural strength remains unchanged.

[0131] exist Figure 2 and Figure 3 In the example shown, the first mounting structure 21 includes a mounting plate 211 extending across the transverse surface within the recess 13, and a mounting portion 212 is provided on the mounting plate 211, the mounting portion 212 being a mounting pin; Figure 4 and Figure 5 In the example shown, the first mounting structure 21 is an L-shaped mounting pin that is locked onto the inner horizontal surface of the recess 13, which helps to seal the top cover of the inner horizontal surface of the recess 13.

[0132] The second connecting structure 32 is integrated onto the bracket body 40, which is rigidly fixed to the vehicle underbody longitudinal beam 200. The first connecting structure 31 is bolted to the vehicle underbody longitudinal beam 200. Furthermore, both the first connecting structure 31 and the second connecting structure 32 are fixed using a single-point unlocking structure; that is, the multiple first connecting parts 312 of the first connecting structure 31 are linked together via a connecting rod 33, and the multiple second connecting parts 322 of the second connecting structure 32 are linked together via a connecting rod 33.

[0133] The battery body 10 adopts an irregular structure, with a concave structure forming a recess 13 in the middle and an inwardly concave structure forming a mounting groove 121 at the ends. This structural form can improve structural strength and utilize space in various positions, thus appropriately increasing energy density. Because this structure has connecting structures in the middle and at both ends of the battery body 10, the connection between the battery 1 and the vehicle underbody longitudinal beam 200 is further strengthened, effectively improving the structural strength of the battery 1 after battery swapping. The entire battery swapping system consists of multiple matched batteries 1, adaptable to different battery swapping scenarios and vehicle models.

Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
