[0003] This application relates to the field of batteries, specifically to a battery mounting bracket, a frame assembly, and a vehicle. Background Technology

[0004] Energy conservation and emission reduction are key to the sustainable development of the automotive industry, and electric vehicles, due to their energy-saving and environmentally friendly advantages, have become an important component of this sustainable development. For electric vehicles, battery technology is a crucial factor in their development. When installing batteries in a vehicle, the limited space available for battery placement restricts the amount of power supplied, affecting the vehicle's driving range per battery swap. Summary of the Invention

[0005] In view of the above problems, this application provides a battery mounting bracket, a frame assembly, and a vehicle that can expand the battery mounting space to increase the driving range of the vehicle on a single battery swap.

[0006] In a first aspect, this application provides a battery mounting bracket for mounting a battery to a vehicle beam. The battery mounting bracket includes a main body and an extension. The main body is connected to the vehicle beam and extends along the length direction of the vehicle beam. The extension forms an angle with the extension direction of the main body and extends in a direction away from the main body. A mounting structure is provided on the extension for mounting the battery.

[0007] In the technical solution of this application embodiment, since the length direction of the extension is at an angle to the extension direction of the main body and extends in a direction away from the main body, and the extension is provided with a mounting structure for mounting the battery, this design can expand the battery mounting space in the vehicle width direction, which is beneficial to increase the size of the battery in the vehicle width direction. Moreover, it is beneficial to flexibly set the distribution position, quantity and structural form of the mounting structure on the extension, so as to improve the mounting strength of large-size batteries, thereby increasing the driving range of the vehicle on a single battery swap.

[0008] In some embodiments, at least one extension on one side of the main body is configured as a plurality and spaced apart along the extension direction of the main body, and a battery mounting space is defined between two adjacent extensions.

[0009] In the technical solution, more extension portions are arranged along the length direction of the vehicle to define more battery mounting spaces, so that more batteries are mounted, thereby increasing the number of mounted batteries while increasing the size of the batteries, and further improving the single battery replacement mileage of the vehicle. Meanwhile, the two extension portions adjacent along the extension direction of the main body portion can serve as the outer walls of the battery mounting spaces to protect the batteries, thereby reducing damage to the batteries and improving the reliability of the batteries in providing power to the vehicle.

[0010] In some embodiments, the side of the extension portion facing the battery mounting space is arranged with a mounting structure.

[0011] In the technical solution, the mounting structure is arranged on the side of the extension portion facing the battery mounting space, thereby reducing the difficulty of arranging the mounting structure, and the mounting structure can be flexibly arranged in a structure form to make the mounting structure more easily and reliably mount the batteries.

[0012] In some embodiments, at least one extension portion in the middle of the plurality of extension portions is a shared extension portion, the shared extension portion has battery mounting spaces on both sides thereof along the extension direction of the main body portion, and the shared extension portion is arranged with a mounting structure on each side thereof facing the battery mounting space.

[0014] In some embodiments, the mounting structures on both sides of the shared extension portion along the extension direction of the main body portion are misaligned in orthographic projection on a projection plane perpendicular to the extension direction of the main body portion.

[0015] In the technical solution, the mounting structures on both sides of the shared extension portion are misaligned in orthographic projection on a projection plane perpendicular to the extension direction of the main body portion, thereby making the stress distribution of the shared extension portion more reasonable, reducing stress concentration when the batteries in the battery mounting spaces on both sides of the shared extension portion are connected to the mounting structures on both sides of the shared extension portion, and improving the service life of the shared extension portion and the mounting reliability of the batteries.

[0016] In some embodiments, the extension portions on both sides of the battery mounting space along the extension direction of the main body portion are each provided with a mounting structure.

[0017] In the technical solution, the extension portions on both sides of the battery mounting space in the extension direction of the main body portion can bear the battery in the battery mounting space, the mounting structures on both sides can disperse the stress, thereby reducing the stress concentration and the deformation or fracture of the extension portions, improving the service life of the extension portions, and improving the mounting reliability of the battery.

[0018] In some embodiments, the mounting structures on both sides of the battery mounting space in the extension direction of the main body portion are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction of the main body portion.

In addition, when the mounting structures on both sides of the extension portions in the extension direction of the main body portion are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction of the main body portion, and the mounting structures on both sides of the battery mounting space in the extension direction of the main body portion are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction of the main body portion, the extension portions can be constructed as the same structure, which helps to reduce the cost and the production process.

[0020] In some embodiments, the side of the extension portion facing the battery mounting space is provided with a plurality of mounting structures, and at least two of the mounting structures are arranged at intervals along the length direction of the extension portion. In the technical solution, the space in the length direction of the extension portion is fully utilized to arrange more mounting structures, thereby improving the mounting stability of the battery or increasing the number of batteries mounted in the battery mounting space.

[0023] In some embodiments, the length direction of the mounting edge is the same as the extension direction of the extension part, and the mounting structure is provided with a plurality of mounting structures arranged at intervals along the length direction of the mounting edge.

[0024] In the above technical solution, since the length direction of the mounting edge is the same as the extension direction of the extension part, the processing difficulty of the mounting edge is reduced, the mounting edge has a greater length size, and a larger number of mounting structures are provided. The plurality of mounting structures are arranged at intervals along the length direction of the mounting edge, thereby enhancing the mounting stability of the battery or increasing the number of batteries mounted on the mounting edge.

[0025] In some embodiments, the length direction of the mounting edge is the same as the extension direction of the extension part, and the mounting structure is provided with a plurality of mounting structures arranged at intervals along the length direction of the mounting edge.

[0108] In the technical scheme, when the battery upper part is mounted from bottom to top, the stop of the bottom of the extension part and the stepped surface can prompt the assembly of the battery to be in place, thereby avoiding the problem that the battery is excessively squeezed and hits the vehicle bottom, and the battery is protected. Moreover, the size of the battery lower part is greater than the size of the battery upper part, thereby further increasing the size of the battery to a certain extent, and the size energy density of the battery is further improved.

[0109] In some embodiments, the battery comprises two battery side parts and a battery central part, the two battery side parts are respectively located on the two sides of the battery central part in the width direction of the vehicle beam, and the top surface of the battery central part is lower than the top surface of the battery side part, so as to form a yielding slot which is through in the length direction of the vehicle beam and open at the top between the two battery side parts and the battery central part.

[0110] In the technical scheme, the structure of the battery is ingenious, the space on the two sides of the width of the vehicle beam is fully utilized by avoiding the vehicle beam, thereby the overall size of the battery can be increased to improve the size energy density of the battery.

[0111] The above description is only a summary of the technical solutions of the present application. In order to make the technical means of the present application more clearly understood and implemented according to the content of the specification, and in order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the following specific embodiments of the present application are described.

For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0143] From the development of the current market situation, the application of power batteries is more and more extensive. Power batteries are not only applied to energy storage power supply systems such as hydroelectric, thermal, wind and solar power stations, but also widely used in electric bicycles, electric motorcycles, electric vehicles and other electric vehicles, military equipment, aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also increasing.

[0144] Some vehicles in the related art have a vehicle beam at the bottom of the vehicle, the length direction of the vehicle beam is consistent with the length direction of the vehicle, the vehicle beam is provided with a mounting structure on each of the two side walls in the width direction of the vehicle, and the power battery is arranged at the bottom of the vehicle and mounted on the mounting structure. However, the mounting structure arranged on the side wall of the vehicle beam occupies the space of the battery in the width direction of the vehicle, which makes it difficult to increase the size of the battery in the width direction of the vehicle, and makes it difficult to improve the size energy density of the battery. Moreover, the side wall space of the vehicle beam is limited, which limits the distribution position, quantity and structure form of the mounting structure, and it is difficult to meet the mounting strength requirement of the large-size battery, which makes it difficult to improve the size energy density of the battery, thereby affecting the single battery replacement mileage of the whole vehicle.

[0145] In order to increase the size energy density of the battery, the present application provides a battery mounting rack, wherein the battery mounting rack comprises a main body part and an extension part, the main body part is used for connecting to the vehicle beam, the extension part is at an angle with the length direction of the vehicle beam and extends in a direction away from the vehicle beam, for example, the extension part is arranged on each of the two sides of the width of the vehicle beam and extends in the width direction of the vehicle beam, and the mounting structure is arranged on the extension part and used for mounting the battery.

[0146] In the process of installing the battery on the vehicle beam by using the battery mounting rack, the extension direction of the extension part where the mounting structure is arranged is at an angle with the length direction of the vehicle beam, so that the extension part and the mounting structure thereon do not occupy the space of the battery in the vehicle width direction, which is beneficial to increase the size of the battery in the vehicle width direction and improve the size energy density of the battery. Moreover, since the extension direction of the extension part is at an angle with the length direction of the vehicle beam, the mounting structure is arranged on the extension part instead of being arranged on the vehicle beam, which can increase the arrangement space of the mounting structure, is beneficial to flexibly arrange the distribution position, quantity and structure form of the mounting structure, meet the mounting strength requirement of the large-size battery, and is beneficial to mount the large-size battery, thereby improving the single battery replacement mileage of the vehicle.

[0147] In short, in the background of increasing demand for the arrangement space of the battery and the single battery replacement mileage of the vehicle, the battery mounting rack of the present application can expand the mounting space of the battery, which is beneficial to increase the size of the mounted battery, thereby improving the single battery replacement mileage of the vehicle.

[0148] The battery disclosed in the embodiments of the present application can be used in an electric device using the battery as a power supply or a variety of energy storage systems using the battery as an energy storage element. The electric device can be, but is not limited to, a mobile phone, a tablet, a notebook computer, an electric toy, an electric tool, an electric vehicle, an electric car, a ship, a spacecraft, etc. Among them, the electric toy can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric plane toys, etc. The spacecraft can include airplanes, rockets, space shuttles, and spaceships, etc.

[0149] The following embodiments are described by taking an embodiment of the present application as an example for the vehicle 1000 for convenience of description.

The vehicle 1000 can be a fuel car, a gas car or a new energy car, and the new energy car can be a pure electric car, a hybrid car or an extended range car, etc. The vehicle 1000 is internally provided with a battery 30, which can be arranged at the bottom, the head or the tail of the vehicle 1000. The battery 30 can be used for power supply of the vehicle 1000, for example, the battery 30 can be used as the operating power supply of the vehicle 1000. The vehicle 1000 can further include a controller 40 and a motor 50, and the controller 40 is used to control the battery 30 to supply power to the motor 50, for example, to meet the working power demand of the vehicle 1000 during starting, navigation and driving.

[0151] In some embodiments of the present application, the battery 30 can not only serve as the operating power source of the vehicle 1000, but also serve as the driving power source of the vehicle 1000, replacing or partially replacing the fuel or natural gas to provide driving power for the vehicle 1000.

[0152] Please refer to Figure 2 , Figure 2 An exploded view of the battery 30 provided in some embodiments of the present application is shown. The battery 30 includes a box body 301 and a battery cell 302, and the battery cell 302 is contained in the box body 301. The box body 301 is used to provide a containing space for the battery cell 302, and the box body 301 can adopt various structures. In some embodiments, referring to Figure 2 , the box body 301 can include a first part 3011 and a second part 3012, the first part 3011 and the second part 3012 are overlapped with each other, and the first part 3011 and the second part 3012 together define a containing space for containing the battery cell 302. The second part 3012 can be a hollow structure with an open end, and the first part 3011 can be a plate structure, the first part 3011 is overlapped with the open end of the second part 3012 to make the first part 3011 and the second part 3012 together define the containing space; the first part 3011 and the second part 3012 can also be hollow structures with an open end on one side, and the open end of the first part 3011 is overlapped with the open end of the second part 3012. Of course, the box body 301 formed by the first part 3011 and the second part 3012 can have various shapes, such as a cylinder, a cuboid, etc.

[0153] The battery 30 can include a battery cell 302, and the battery cell 302 can be multiple, and the multiple battery cells 302 can be connected in series, in parallel, or in a mixed connection, where the mixed connection means that the multiple battery cells 302 are connected in series and in parallel. The multiple battery cells 302 can be directly connected in series, in parallel, or in a mixed connection, and then the whole of the multiple battery cells 302 is contained in the box body 301; of course, the battery 30 can also be that the multiple battery cells 302 are first connected in series, in parallel, or in a mixed connection to form a battery module, and then multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and the whole is contained in the box body 301. The battery 30 can also include other structures, for example, the battery 30 can also include a busbar for realizing the electrical connection between the multiple battery cells 302.

[0154] In the present application, the battery cell 302 can include a lithium ion secondary battery, a lithium ion primary battery, a lithium-sulfur battery, a sodium lithium ion battery, a sodium ion battery, or a magnesium ion battery, etc., and the present application embodiment is not limited thereto. The battery cell 302 can be in the shape of a cylinder, a flat body, a cuboid, or other shapes, etc., and the present application embodiment is not limited thereto. The battery cell 302 is generally divided into three types according to the packaging method: a cylindrical battery cell, a square battery cell, and a soft package battery cell, and the present application embodiment is not limited thereto.

[0155] The battery cell 302 includes a housing, an electrode assembly, and an electrolyte, and the housing is used to accommodate the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode tab, a negative electrode tab, and a separator. The battery cell 302 mainly relies on the movement of metal ions between the positive electrode tab and the negative electrode tab to work. The material of the separator is not limited, for example, it can be polypropylene or polyethylene, etc.

[0156] The positive electrode tab can generally include a positive electrode current collector and a positive electrode active material layer, and the positive electrode active material layer is directly or indirectly coated on the positive electrode current collector. The positive electrode current collector that has not been coated with the positive electrode active material layer protrudes from the positive electrode current collector that has been coated with the positive electrode active material layer, and the positive electrode current collector that has not been coated with the positive electrode active material layer serves as a positive electrode tab. Taking a lithium ion battery as an example, the material of the positive electrode current collector can be aluminum, and the material of the positive electrode active material layer can be lithium cobaltate, lithium iron phosphate, ternary lithium, or lithium manganate, etc.

[0157] The negative electrode tab can generally include a negative electrode current collector and a negative electrode active material layer, and the negative electrode active material layer is directly or indirectly coated on the negative electrode current collector. The negative electrode current collector that has not been coated with the negative electrode active material layer protrudes from the negative electrode current collector that has been coated with the negative electrode active material layer, and the negative electrode current collector that has not been coated with the negative electrode active material layer serves as a negative electrode tab. The material of the negative electrode current collector can be copper, and the material of the negative electrode active material layer can be carbon or silicon, etc.

[0158] In order to ensure that no fusing occurs when passing a large current, the number of positive electrode tabs is multiple and stacked together, and the number of negative electrode tabs is multiple and stacked together. The electrode assembly can be a wound structure or a stacked structure, and the present application embodiment is not limited thereto.

[0159] As shown in Figure 1 , the present application embodiment provides a battery mounting rack 10 for mounting a battery 30 to a vehicle beam 20. As shown in Figure 3 and Figure 4 , the connection between the battery mounting rack 10 and the vehicle beam 20, the battery 30 is shown, Figure 3 , the connection between the battery mounting rack 10 and the vehicle beam 20 is shown. Figure 4 , the connection between the battery mounting rack 10 and the vehicle beam 20 is shown.

[0160] As shown in Figure 3 , the connection between the battery mounting rack 10 and the vehicle beam 20, the battery 30 is shown,Figure 4 As shown, in some embodiments, the battery mounting rack 10 comprises a main body part 1 and an extension part 2. The main body part 1 is configured to be connected to the vehicle beam 20 and extend along the length direction of the vehicle beam 20, and the extension part 2 extends along a direction (e.g., the second direction Y) that is at an angle to the extension direction (e.g., the first direction X) of the main body part 1 and away from the main body part 1. The extension part 2 is provided with a mounting structure 3 configured to mount the battery 30.

[0161] It is worth noting that the battery mounting rack 10 of the embodiments of the present application can be used for battery swapping under frame of the vehicle 1000. Battery swapping under frame refers to a mode of realizing vehicle energy supply by flexibly replacing the swappable battery system mounted under the frame of the vehicle. The swappable battery system refers to the overall replacement of the power battery system (referred to as battery 30 in the present application) of the vehicle 1000 during battery swapping. Exemplarily, the swappable battery system generally comprises a power storage battery, a battery management system, a battery swapping electrical interface, a battery swapping cooling interface, and a battery swapping mechanical interface, etc., and can be charged and discharged in a non-vehicle-mounted state. The terms and definitions of the embodiments of the present application can refer to GB / T 19596 Electric Vehicle Terminology.

[0162] The vehicle beam 20 is a vehicle floor longitudinal beam or a vehicle floor girder of the vehicle 1000, and the length direction of the vehicle beam 20 is consistent with the length direction of the vehicle 1000, i.e., the front-rear direction of the vehicle. The "main body part 1 extends along the length direction of the vehicle beam 20" means that the extension direction (e.g., the first direction X) of the main body part 1 is consistent with the length direction of the vehicle beam 20, i.e., the front-rear direction of the vehicle 1000. Therefore, the "length direction (e.g., the second direction Y) of the extension part 2 is at an angle to the extension direction (e.g., the first direction X) of the main body part 1" can be understood as that the extension direction of the extension part 2 intersects with the length direction of the vehicle 1000, for example, at an acute angle, a right angle, or an obtuse angle.

[0163] In this way, the extension part 2 and the battery 30 can be arranged along the length direction of the vehicle 1000, for example, the extension part 2 can be located at the front side and / or the rear side of the battery 30. The extension part 2 and the mounting structure 3 provided on the extension part 2 occupy the space of the battery 30 other than the battery 30 in the length direction of the vehicle 1000, for example, the space of the front side and / or the rear side of the battery 30, but do not occupy the space of the battery 30 other than the battery 30 in the width direction of the vehicle 1000, for example, the space of the left and right sides of the battery 30, thereby facilitating the increase of the size of the battery 30 in the width direction of the vehicle, for example, the size of the battery 30 in the left-right direction.

[0164] It can be understood that the length of the vehicle 1000 is greater than the width of the vehicle 1000, the length direction of the vehicle 1000 has a larger accommodation space, and the accommodation space in the width direction of the vehicle 1000 is limited. By arranging the extension part 2 and the mounting structure 3 on the front and rear sides of the battery 30, the extension part 2 and the mounting structure 3 can be arranged in the relatively sufficient space, so as to avoid occupying the space on the left and right sides of the battery 30, thereby increasing the size of the battery 30 by using the saved space in the left and right directions, and improving the size energy density of the battery 30.

[0165] Moreover, compared with the scheme of arranging the mounting structure on the two side walls of the vehicle beam, since the length direction (such as the second direction Y) of the extension part 2 of some embodiments of the present application and the extension direction (such as the first direction X) of the main body part 1 are at an angle, the extension part 2 can have relatively sufficient space to arrange the mounting structure 3, so as to flexibly arrange the distribution position, quantity and structure form of the mounting structure 3 on the extension part 2, which is beneficial to improve the mounting strength of the battery 30 mounted on the mounting structure 3, improve the mounting reliability of the battery 30, and thus improve the single battery replacement mileage of the vehicle 1000.

[0166] Among them, the structure of the mounting structure 3 is not limited, for example, can include but is not limited to mounting slot, or mounting hole, or mounting protrusion, or mounting pin, or mounting screw, etc., which is not limited here.

[0167] In addition, it should be noted that the connection mode of the main body part 1 and the vehicle beam 20 is not limited, which can be directly connected with the part of the vehicle beam 20 facing the main body part 1, or indirectly connected with the external part arranged on the vehicle beam 20 facing the main body part 1.

[0168] In addition, it should be noted that the connection position of the main body part 1 and the vehicle beam 20 is not limited, for example, can be connected to at least one of the top, bottom or side of the vehicle beam 20.

[0169] In some embodiments, please refer to Figure 3 and Figure 4 The extension part 2 on at least one side of the main body part 1 in the width direction (such as the second direction Y) is configured to be multiple and arranged at intervals along the extension direction (such as the first direction X) of the main body part 1, and the battery mounting space 4 is defined between two adjacent extension parts 2 along the extension direction (such as the first direction X) of the main body part 1. It should be noted that the width direction (such as the second direction Y) of the main body part 1 is consistent with the width direction (for example, the direction Y shown in 3) of the vehicle beam 20, such as the left and right directions of the vehicle 1000.

[0170] At least one side of the main body 1 in the width direction (such as the second direction Y) is provided with a plurality of extension portions 2, and the plurality of extension portions 2 on the same side of the main body 1 in the width direction (such as the second direction Y) are arranged at intervals along the extension direction (such as the first direction X) of the main body 1. For example, at least one of the left side and the right side of the main body 1 can be provided with a plurality of extension portions 2 arranged at intervals in the front-rear direction.

[0171] It can be understood that the mounting structure 3 on the extension portion 2 is used to mount the battery 30 to the battery mounting space 4, that is, when the battery 30 is connected to the mounting structure 3, at least part of the battery 30 can be accommodated in the battery mounting space 4, and the mounting state is presented.

[0172] In the above technical solution, the two adjacent extension portions 2 along the extension direction (such as the first direction X) of the main body 1 can act as the outer wall of the battery mounting space 4 to protect the battery 30 to some extent, so as to reduce the damage of the battery 30 and improve the reliability of the battery 30 providing power for the vehicle 1000.

[0173] In addition, since the extension portion 2 is configured as a plurality and arranged at intervals along the extension direction (such as the first direction X) of the main body 1, it is beneficial to fully utilize the space in the length direction of the vehicle 1000 to arrange more extension portions 2, so as to define more battery mounting spaces 4, thereby mounting more batteries 30, so as to increase the mounting number of the battery 30 while increasing the size of the battery 30, and further improve the single battery replacement mileage of the vehicle 1000.

[0174] For example, please refer again to Figure 3 and Figure 4 Four extension portions 2 are arranged on the width side of the vehicle beam 20, the four extension portions 2 are arranged at intervals along the extension direction (such as the first direction X) of the main body 1, and the four extension portions 2 define three battery mounting spaces 4, each of which can mount at least one battery 30, and when the battery 30 is mounted on the mounting structure 3, at least part of the battery 30 is located in the battery mounting space 4. At this time, the two adjacent extension portions 2 can act as the outer wall of the battery mounting space 4 to protect the battery 30 to some extent, so as to reduce the damage of the battery 30 and improve the reliability of the battery 30 providing power for the vehicle 1000.

[0175] Of course, the number of extension portions 2 described above is only used for illustration, for example, the extension portions 2 on the width side of the vehicle beam 20 can also be provided with three, or five, or more, etc., which can be set according to the specific needs of the vehicle 1000.

[0176] When the battery mounting rack 10 includes multiple battery mounting spaces 4, the extension 2 between two battery mounting spaces 4 can be used to isolate the batteries 30 in the two adjacent battery mounting spaces 4, thereby improving the mutual knocking and heat transfer of the batteries 30 in the two adjacent battery mounting spaces 4. Of course, the battery mounting rack 10 can also include only one battery mounting space 4.

[0177] In some embodiments, the battery mounting space 4 penetrates in the height direction (such as the third direction Z) of the extension 2. Here, "the battery mounting space 4 penetrates in the height direction of the extension 2" means that the two ends of the battery mounting space 4 in the height direction of the extension 2 are open and not blocked by the structure on the battery mounting rack 10. Here, the height direction of the extension 2 can be a direction perpendicular to the thickness direction (such as the first direction X) of the extension 2 and the length direction (the second direction Y) of the extension 2.

[0178] For example, the height direction of the extension 2 can be set to coincide with the height direction of the vehicle 1000, so that when the battery 30 is mounted in the battery mounting space 4, the battery 30 can be free from the obstruction of the battery mounting rack 10 in the height direction of the vehicle 1000, i.e., the extension 2, the main body 1, and the mounting structure 3 do not occupy the space of the battery 30 in the height direction of the vehicle 1000, thereby improving the space utilization of the battery 30 in the height direction of the vehicle 1000, facilitating the increase of the size of the battery 30 in the height direction of the vehicle 1000, facilitating the increase of the size-energy density of the battery 30, thereby improving the single-replacement mileage of the vehicle 1000 and ensuring the ground clearance of the battery 30 and the passability of the vehicle 1000. Moreover, it is also conducive to the heat dissipation of the battery 30. Furthermore, it is also conducive to reducing the weight of the battery mounting rack 10 and the vehicle-mounted burden of the battery mounting rack 10.

[0179] Some vehicles in the related art generally use a tray to mount a battery pack at the bottom of the vehicle, i.e., placing the battery pack on the tray and then mounting the tray to the bottom of the vehicle. When replacement is needed, the tray is removed, the entire battery pack in the tray is replaced, and then the tray is mounted back to the bottom of the vehicle. However, when replacement is needed, the energy of the battery pack in the tray is usually not fully used, and thus replacement at this time causes energy waste.

[0180] In the embodiments of the present application, the battery mounting rack 10 includes multiple battery mounting spaces 4 arranged in sequence in the extension direction (such as the first direction X) of the main body 1, and the battery mounting rack 10 is provided with a mounting structure 3 corresponding to each battery mounting space 4, so that each battery mounting space 4 can be used to mount a battery 30, and the mounting structures 3 corresponding to different battery mounting spaces 4 can be independent of each other, so that each battery mounting space 4 can individually replace the mounted battery 30. Here, the "corresponding" of the mounting structure 3 to the battery mounting space 4 arrangement means the correspondence in the relationship, including but not limited to the correspondence in the position.

[0181] But not limited to, for example, in some embodiments, when a plurality of battery mounting spaces 4 are used to mount the same battery 30, for example, two battery mounting spaces 4 corresponding to the arrangement along the second direction Y are used to mount the same battery 30, the mounting structure 3 corresponding to the two battery mounting spaces 4 respectively can be arranged independently, or can also be arranged in the form of linkage, so that when mounting the same battery 30, the mounting structure 3 in the form of linkage is beneficial to improve the battery replacement efficiency.

[0182] It can be understood that when the size of the battery 30 is large, the same battery 30 can be installed in multiple battery mounting spaces 4 at the same time, and when the size of the battery 30 is small, one battery 30 can be arranged corresponding to one battery mounting space 4, or multiple batteries 30 can be arranged corresponding to one battery mounting space 4, that is, the specific mounting method depends on the form of the battery 30, which is not limited here.

[0183] When the battery 30 is installed on the vehicle using such a battery mounting rack 10, since the battery mounting rack 10 includes multiple battery mounting spaces 4, and the mounting structure 3 is arranged on the battery mounting rack 10 so that each battery mounting space 4 can be used to mount the battery 30, each battery mounting space 4 can be individually mounted with the battery 30, so that the battery mounting rack 10 can have the function of installing multiple batteries 30, when replacing the battery, only the battery 30 with the power used up can be replaced, while the battery 30 with the power not used up is retained, thereby improving the energy utilization rate of the battery 30 and improving the energy waste problem.

[0184] In some embodiments, please refer to Figures 4-6 , Figure 5 is Figure 4 a partial enlarged view of part A in FIG. 8, Figure 6 is Figure 4 a connection front projection view of the battery mounting rack 10 and the vehicle beam 20 shown in FIG. 8, the mounting structure 3 is arranged on the side of the extension part 2 facing the battery mounting space 4. That is, the extension part 2 includes a mounting surface 23 facing the battery mounting space 4, and the mounting structure 3 is arranged on the side of the mounting surface 23 facing the battery mounting space 4.

[0185] In this way, the mounting structure 3 is arranged towards which battery mounting space 4 corresponds, for mounting the battery 30 to the battery mounting space 4 towards which the mounting structure 3 is arranged, so that the correspondence between the mounting structure 3 and the battery mounting space 4 can be clear, and the battery 30 can be conveniently mounted by being inserted into the battery mounting space 4 and connected to the mounting structure 3 arranged towards the battery mounting space 4. Moreover, when there are multiple battery mounting spaces 4, the mounting structures 3 corresponding to different battery mounting spaces 4 are arranged at different positions and do not interfere with each other, so that the mounting structure 3 corresponding to each battery mounting space 4 can be arranged flexibly in sufficient space, so that the battery 30 can be more easily and reliably mounted by the mounting structure 3. Therefore, by arranging the mounting structure 3 on the side of the extension 2 towards the battery mounting space 4, the arrangement difficulty of the mounting structure 3 can be reduced, and the mounting structure 3 can be arranged flexibly in sufficient space, so that the battery 30 can be more easily and reliably mounted by the mounting structure 3.

[0186] In some embodiments, referring again to Figures 4-6 , at least one of the extensions 2 in the middle of the multiple extensions 2 is a shared extension 2a, the shared extension 2a has battery mounting spaces 4 on both sides in the extension direction (such as the first direction X) of the main body 1, and the mounting structure 3 is arranged on both sides of the shared extension 2a towards the battery mounting spaces 4 on both sides.

[0187] It is worth noting that "at least one of the extensions 2 in the middle of the multiple extensions 2" refers to at least one of the extensions 2 in the middle of the multiple extensions 2 arranged at intervals in the extension direction (such as the first direction X) of the main body 1, except for the two extensions 2 on both sides. For example, when there are four extensions 2 on one side of the width of the vehicle beam 20, at least one of the two extensions 2 in the middle is a shared extension 2a. The shared extension 2a has two mounting surfaces 23 respectively towards the battery mounting spaces 4 on both sides.

[0188] Therefore, when the number of battery mounting spaces 4 arranged at intervals in the extension direction (such as the first direction X) of the main body 1 is fixed, the number of extensions 2 arranged at intervals in the extension direction (such as the first direction X) of the main body 1 can be reduced, for example, in the worst case, the number of extensions 2 on one side of the width of the vehicle beam 20 can be one more than the number of battery mounting spaces 4, that is, only one extension 2 is arranged between two adjacent battery mounting spaces 4 in the extension direction (such as the first direction X) of the main body 1, thereby facilitating cost reduction and load reduction of the vehicle 1000.

[0189] However, the application is not limited thereto, for example, two extension portions 2 can be arranged between two battery mounting spaces 4 adjacent in the extension direction (such as the first direction X) of the main body portion 1, so that each extension portion 2 can correspond to only one side of the battery mounting space 4 to arrange the mounting structure 3, thereby reducing the bearing force of each extension portion 2 on the battery and improving the mounting reliability of the battery 30.

[0190] In some embodiments, referring again to Figures 4-6 , the mounting structures 3 on both sides of the common extension portion 2a in the extension direction (such as the first direction X) of the main body portion 1 are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction (such as the first direction X) of the main body portion 1. That is, the orthographic projections of the mounting structures 3 on the two mounting installation surfaces 23 of the common extension portion 2a in the extension direction (such as the first direction X) of the main body portion 1 are misaligned. For example, the distance from any mounting structure 3 on one side of the common extension portion 2a to the main body portion 1 in the length direction (such as the second direction Y) of the extension portion 2 is different from the distance from any mounting structure 3 on the other side of the common extension portion 2a to the main body portion 1 in the length direction (such as the second direction Y) of the extension portion 2.

[0191] Therefore, by misaligning the orthographic projections of the mounting structures 3 on both sides of the common extension portion 2a in the extension direction (such as the first direction X) of the main body portion 1 on the projection plane perpendicular to the extension direction (such as the first direction X) of the main body portion 1, the stress distribution of the common extension portion 2a is more reasonable, and when the batteries 30 in the battery mounting spaces 4 on both sides of the common extension portion 2a are connected to the mounting structures 3 on both sides of the common extension portion 2a, respectively, the stress concentration is reduced, and problems such as deformation and fracture of the extension portion 2 are avoided, the service life of the common extension portion 2a is improved, and the mounting reliability of the battery 30 is improved.

[0192] In some embodiments, referring again to Figures 4-6 , the mounting structures 3 are arranged on both sides of the extension portion 2 in the extension direction (such as the first direction X) of the main body portion 1. For example, the mounting installation surface 23 includes a first mounting installation surface 231 and a second mounting installation surface 232, the first mounting installation surface 231 and the second mounting installation surface 232 are respectively one side surface of two adjacent extension portions 2 facing the same battery mounting space 4, the side of the first mounting installation surface 231 facing the battery mounting space 4 is provided with a mounting structure 3, and the side of the second mounting installation surface 232 facing the battery mounting space 4 is also provided with a mounting structure 3, and the battery 30 in the battery mounting space 4 is connected to the two mounting structures 3, respectively.

[0193] Therefore, the extension portions 2 on both sides of the battery mounting space 4 in the extension direction (such as the first direction X) of the main body portion 1 can bear the battery 30 in the battery mounting space 4, and the mounting structures 3 on both sides can disperse the stress to reduce the stress concentration and the deformation, fracture and other problems of the extension portions 2, improve the service life of the common extension portion 2a, and improve the mounting reliability of the battery 30.

[0194] Further, in some embodiments, the mounting structures 3 on both sides of the battery mounting space 4 in the extension direction (such as the first direction X) of the main body portion 1 are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction (such as the first direction X) of the main body portion 1. For example, the distance from the mounting structure 3 on one side of the battery mounting space 4 to the main body portion 1 in the length direction (such as the second direction Y) of the extension portion 2 is different from the distance from the mounting structure 3 on the other side of the battery mounting space 4 to the main body portion 1 in the length direction (such as the second direction Y) of the extension portion 2.

[0195] Therefore, by misaligning the mounting structures 3 on both sides of the battery mounting space 4 in the orthographic projection on the projection plane perpendicular to the extension direction (such as the first direction X) of the main body portion 1, the mounting structures 3 on both sides can further disperse the stress, and further improve the deformation, fracture and other problems of the extension portions 2 caused by stress concentration.

[0196] In addition, when the mounting structures 3 on both sides of the common extension portion 2a in the extension direction (such as the first direction X) of the main body portion 1 are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction (such as the first direction X) of the main body portion 1, and the mounting structures 3 on both sides of the battery mounting space 4 in the extension direction (such as the first direction X) of the main body portion 1 are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction (such as the first direction X) of the main body portion 1, the multiple extension portions 2 can be constructed as the same structure to reduce the cost and the production process.

[0197] Of course, the present application is not limited thereto, for example, the mounting structures 3 on both sides of the common extension portion 2a in the extension direction (such as the first direction X) of the main body portion 1 can be aligned in the orthographic projection on the projection plane perpendicular to the extension direction (such as the first direction X) of the main body portion 1, and at this time, the mounting structures 3 on both sides of the battery mounting space 4 in the extension direction (such as the first direction X) of the main body portion 1 can also be aligned in the orthographic projection on the projection plane perpendicular to the extension direction (such as the first direction X) of the main body portion 1, so that the processing can be simplified and the cost can be reduced.

[0198] In some embodiments, please refer to Figure 4 and Figure 5 The side of the extension portion 2 facing the battery mounting space 4 is provided with multiple mounting structures 3, and at least two mounting structures 3 are arranged in the length direction (such as the second direction Y) of the extension portion 2.

[0199] In this way, it is beneficial to make full use of the space in the length direction (e.g., the second direction Y) of the extension part 2 to arrange a larger number of mounting structures 3, thereby facilitating the enhancement of the mounting stability of the battery 30 or the increase of the number of batteries 30 mounted in the battery mounting space 4.

[0200] In some embodiments, referring to Figure 5 , the extension part 2 includes a mounting edge 24 protruding into the battery mounting space 4, and the mounting structure 3 is located on the mounting edge 24. For example, the mounting edge 24 protrudes in the direction of the inside of the battery mounting space 4 along the extension direction (e.g., the first direction X) of the main body part 1.

[0201] In this way, by providing the mounting edge 24, it is beneficial to reduce the difficulty of arranging the mounting structure 3, and it is easy to realize that the mounting structure 3 is located on the side of the extension part 2 facing the battery mounting space 4, and the mounting edge 24 can directly or indirectly support the battery 30 to some extent, thereby enhancing the mounting stability of the battery 30.

[0202] In some embodiments, referring to Figure 4 and Figure 5 , the mounting edge 24 is located on the lower edge of the extension part 2 in the height direction (e.g., the third direction Z). Here, the two ends of the extension part 2 in the height direction (e.g., the third direction Z) are defined as the upper and lower ends, and when the height direction of the extension part 2 is consistent with the height direction of the vehicle 1000, the two ends of the extension part 2 in the height direction are also the upper and lower ends in the direction of gravity.

[0203] In this way, the mounting structure 3 is arranged at a low height, which is beneficial to reduce the difficulty of maintaining the mounting structure 3, and is beneficial to the loading connection of the mounting structure 3 and the battery 30, improves the compactness of the cooperation between the battery 30 and the extension part 2, reduces the waste of space, and further increases the size of the battery 30 by saving space, thereby further improving the size energy density of the battery 30.

[0204] For example, when a tool is used to extend upward to the position of the mounting structure 3 to perform the mounting connection of the mounting structure 3 and the battery 30, the tool is lifted to a position lower than the extension part 2, thereby reducing the lifting height of the tool, and the tool does not need to extend into the space between the battery 30 and the extension part 2, and the gap between the battery 30 and the extension part 2 does not need to be increased to meet the extension requirement of the tool, thereby reducing the waste of space, further increasing the size of the battery 30 by saving space, and further improving the size energy density of the battery 30.

[0205] In some embodiments, referring to Figure 4 and Figure 5The length direction of the mounting edge 24 is the same as the length direction of the extension 2 (e.g., the second direction Y), and the mounting edge 24 is provided with a plurality of mounting structures 3 arranged at intervals along the length direction of the mounting edge 24.

[0206] Therefore, since the length direction of the mounting edge 24 is the same as the length direction of the extension 2 (e.g., the second direction Y), the processing difficulty of the mounting edge 24 is reduced, so that the mounting edge 24 has a greater length size, and a larger number of mounting structures 3 are arranged, and the plurality of mounting structures 3 are arranged at intervals along the length direction of the mounting edge 24, so as to enhance the mounting stability of the battery 30, or increase the number of batteries 30 mounted on the mounting edge 24.

[0207] In some embodiments, referring to Figure 7 , Figure 7 FIG. 8 is a partial enlarged view of the battery mounting rack 10 according to another embodiment of the present application, the length direction of the mounting edge 24 is the same as the length direction of the extension 2 (e.g., the second direction Y), and the mounting structure 3 on the mounting edge 24 is configured as one and extends along the length direction of the mounting edge 24.

[0208] Therefore, by arranging only one mounting structure 3 on the mounting edge 24, the processing difficulty of the mounting structure 3 is reduced, and the mounting structure 3 extends along the length direction of the mounting edge 24, that is, the length direction of the mounting structure 3 is consistent with the length direction of the mounting edge 24, so that the size of the mounting structure 3 is larger, has a greater force area, or has more connection positions, so as to be connected with a plurality of connection structures on the battery 30 at the same time, improve the mounting reliability of the battery 30, or mount a plurality of batteries 30 at the same time.

[0209] In some embodiments, one side of the main body 1 in the width direction (e.g., the second direction Y) is arranged with the extension 2. It should be noted that the width direction (e.g., the second direction Y) of the main body 1 is consistent with the width direction of the vehicle beam 20, and the width direction of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. For example, the left side of the main body 1 is provided with the extension 2, or the right side of the main body 1 is provided with the extension 2.

[0210] Therefore, by arranging the extension 2 on only one side of the main body 1 in the width direction (e.g., the second direction Y), the force transmitted from the extension 2 mounted with the battery 30 to the main body 1 can be reduced, so as to improve the connection reliability of the extension 2 and the main body 1, and improve the connection reliability of the main body 1 and the vehicle beam 20, thereby improving the mounting reliability of the battery 30.

[0211] It is worth mentioning that if the extension 2 is arranged on one side of the main body 1 in the width direction (such as the second direction Y), and it is also desired that the extension 2 is arranged on both sides of the vehicle beam 20 in the width direction, at least two main bodies 1 can be mounted on the vehicle beam 20, one of which is arranged with the extension 2 on the left side, and the other of which is arranged with the extension 2 on the right side, so that the extension 2 can be arranged on both sides of the vehicle beam 20.

[0212] In some embodiments, referring to Figure 3 and Figure 4 , the extension 2 is arranged on each of the two sides of the main body 1 in the width direction (such as the second direction Y). That is, the extension 2 on the main body 1 is provided in multiple, at least two of which are respectively arranged on the two sides of the main body 1 in the width direction (such as the second direction Y). It is worth mentioning that the width direction of the main body 1 (such as the second direction Y) is consistent with the width direction of the vehicle beam 20, and the width direction of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. For example, the left side of the main body 1 is provided with the extension 2, and the right side of the main body 1 is also provided with the extension 2.

[0213] Therefore, by arranging the extension 2 on both sides of the main body 1 in the width direction (such as the second direction Y), the vehicle beam 20 can have the extension 2 on both sides by connecting only one main body 1 to the vehicle beam 20, so that the extension 2 on both sides of the main body 1 can be used to mount the battery 30 respectively, for example, two parts of the same battery 30 on both sides of the vehicle beam 20 in the width direction, or two batteries 30 on both sides of the vehicle beam 20 in the width direction, so as to increase the mounting strength of the battery 30, or increase the number of mounted batteries 30.

[0214] In some embodiments, referring to Figure 3 and Figure 4 , the extension 2 includes a first extension 21 and a second extension 22 arranged on the two sides of the main body 1 in the width direction (such as the second direction Y) respectively, the extension directions of the first extension 21 and the second extension 22 are the same, and the first extension 21 and the second extension 22 are projected to coincide along the extension direction of the first extension 21.

[0215] It is worth mentioning that the width direction of the main body 1 (such as the second direction Y) is consistent with the width direction of the vehicle beam 20, such as the left-right direction of the vehicle 1000. For example, the first extension 21 and the second extension 22 both extend in the width direction of the vehicle beam 20, or the first extension 21 and the second extension 22 both extend in a direction inclined to the width direction of the vehicle beam 20, and the angles of inclination are the same.

[0216] Thus, by setting the extension directions of the first extension 21 and the second extension 22 to be the same, and by setting the projections of the first extension 21 and the second extension 22 along the extension direction of the first extension 21 to coincide, the first extension 21 and the second extension 22 can simultaneously mount the two parts of the same battery 30 located on both sides of the vehicle beam 20 in the width direction, so that the size of the battery 30 can be made larger, so as to reduce the number of batteries 30 and reduce the complexity of battery replacement.

[0217] In some embodiments, please refer to Figure 3 and Figure 4 When at least one side of the body part 1 in the width direction (such as the second direction Y) is provided with a plurality of extensions 2 arranged at intervals along the extension direction of the body part 1 (such as the first direction X), the battery mounting rack 10 further comprises a reinforcing part 5, and the reinforcing part 5 is used to connect at least two extensions 2 located on the same side of the body part 1 in the width direction (such as the second direction Y). It should be noted that the present embodiment is applicable to both the case of "arranging at least one extension 2 on each of the two sides of the body part 1 in the width direction" and the case of "arranging extensions 2 on one side of the body part 1 in the width direction". In addition, the at least two extensions 2 connected by the reinforcing part 5 can be adjacent or non-adjacent.

[0218] In addition, it should be noted that the width direction of the body part 1 (such as the second direction Y) is consistent with the width direction of the vehicle beam 20, such as the left-right direction of the vehicle 1000. For example, at least two extensions 2 on the left side of the body part 1 are connected by the reinforcing part 5, and / or at least two extensions 2 on the right side of the body part 1 are connected by the reinforcing part 5.

[0219] Thus, it is beneficial to enhance the overall structural strength of the battery mounting rack 10, reduce the deformation of the extension 2 caused by stress, and improve the mounting reliability of the battery 30.

[0220] In some embodiments, the reinforcing part 5 and the body part 1 are located on both sides of the extension 2 in the length direction (such as the second direction Y). Thus, the two extensions 2 defining the battery mounting space 4 can be connected by the body part 1 and the reinforcing part 5 at both ends of the extension 2 in the length direction (such as the second direction Y). In this way, the structure around the battery mounting space 4 is formed in a ring shape, which has higher structural strength and higher mounting reliability for the battery 30, and can more comprehensively protect the battery 30 from the side, and the position of the mounting structure 3 can be flexibly selected.

[0221] In some embodiments, please refer to Figure 5 The height of the extension 2 (i.e., the size in the height direction of the extension 2 (such as the third direction Z)) decreases in the direction away from the body part 1. It should be noted that "decreases" can be gradual or stepwise.

[0222] Therefore, by setting the height of the extension portion 2 to decrease along the direction away from the main body portion 1, the height of the region of the extension portion 2 away from the main body portion 1 is smaller, that is, the height of the end portion of the extension portion 2 connected to the main body portion 1 is relatively large, and the height of the end portion of the extension portion 2 away from the main body portion 1 is relatively small, so that the connection strength of the extension portion 2 and the main body portion 1 can be enhanced, the mounting reliability of the extension portion 2 to the battery 30 can be improved, and the weight of the extension portion 2 can be reduced, thereby reducing the load of the vehicle 1000.

[0223] When the mounting structure 3 is located at the lower edge of the extension portion 2, for example, on the mounting edge 24, and the mounting edge 24 is located at the position of the lower edge of the extension portion 2, the lower edge of the extension portion 2 can be set to extend horizontally, and the upper edge of the extension portion 2 can be set to decrease along the direction away from the main body portion 1. It is worth noting that the "decrease" can be gradual or stepped. Therefore, it is beneficial for the mounting structure 3 to be located at the same horizontal height, thereby facilitating the mounting operation of the battery 30.

[0224] In some embodiments, in combination with Figure 7 As shown, the extension portion 2 is further provided with a reinforcing rib 25. The structure of the reinforcing rib 25 is not limited, for example, it can be linear, or curved, or cross-shaped, etc. Therefore, by setting the reinforcing rib 25, the structural strength of the extension portion 2 can be enhanced, and the problem of stress deformation of the extension portion 2 can be improved.

[0225] Exemplarily, generally, the farther the extension portion 2 is from the main body portion 1, the more likely it is to deform. At least part of the reinforcing rib 25 can be arranged near the middle of the length direction (such as the second direction Y) of the extension portion 2, that is, in the middle or generally in the middle, for example, in the position range between 1 / 3-2 / 3 of the length direction of the extension portion 2. In this way, the number of reinforcing ribs 25 can be reduced, and the effect of improving the structural strength of the extension portion 2 and the mounting reliability of the extension portion 2 to the battery 30 can be better improved.

[0226] Exemplarily, when the battery 30 is mounted on the mounting structure 3 of the extension portion 2, the position of the mounting structure 3 of the extension portion 2 is stressed and deformed, and thus at least part of the reinforcing rib 25 can be arranged corresponding to the mounting structure 3 along the height direction (such as the third direction Z) of the extension portion 2, so that the number of reinforcing ribs 25 can be reduced, and the effect of improving the structural strength of the extension portion 2 and the mounting reliability of the extension portion 2 to the battery 30 can be better improved.

[0227] Exemplarily, when a plurality of mounting structures 3 are arranged on the extension part 2, at least part of the reinforcing ribs 25 are arranged between two adjacent mounting structures 3 along the height direction (such as the third direction Z) of the extension part 2. When the battery 30 is mounted on the mounting structure 3 of the extension part 2, the position of the mounting structure 3 of the extension part 2 is subjected to stress concentration and is prone to deformation and damage. When at least part of the reinforcing ribs 25 are arranged between two adjacent mounting structures 3, the structural strength of the extension part 2 between the two adjacent mounting structures 3 can be enhanced, the problem of fracture due to stress concentration between the two adjacent mounting structures 3 can be improved, and the mounting reliability of the extension part 2 for the battery 30 can be improved.

[0228] In some embodiments, referring to Figure 5 , the extension part 2 is provided with a first weight-reducing structure 26. For example, the first weight-reducing structure 26 can include but is not limited to a weight-reducing hole, or a weight-reducing groove, or a thinning treatment, etc.

[0229] In this way, by arranging the first weight-reducing structure 26, the weight of the extension part 2 can be reduced, and the lightweight design of the battery mounting rack 10 can be facilitated.

[0230] In some embodiments, referring to Figure 4 , the main body part 1 includes a vehicle beam avoiding groove 13 having an opening penetrating along the extension direction (such as the first direction X) of the main body part 1.

[0231] Therefore, by arranging the vehicle beam avoiding groove 13 and the opening penetrating along the extension direction (such as the first direction X) of the main body part 1, at least part of the vehicle beam 20 can be accommodated in the vehicle beam avoiding groove 13, and the opening can avoid the vehicle beam 20, so as to avoid the interference between the battery mounting rack 10 and the vehicle beam 20, thereby reducing the difficulty of mounting and dismounting the battery mounting rack 10, improving the compactness of the main body part 1 and the vehicle beam 20, fully utilizing the space near the vehicle beam 20 to arrange the battery 30, and facilitating the increase of the size of the battery 30.

[0232] It is worth noting that the specific structure of the vehicle beam 20 according to the embodiments of the present application is not limited, for example, can include two longitudinal beams 201 extending along the length direction (such as the first direction X) of the vehicle 1000 and at least one transverse beam 202 extending along the width direction (such as the second direction Y) of the vehicle 1000, the two longitudinal beams 201 are arranged in the width direction of the vehicle 1000, and the transverse beam 202 is connected between the two longitudinal beams 201.

[0233] In some embodiments, referring to Figure 4The main body 1 includes a first main body wall 11 arranged along a width direction (e.g., the second direction Y) of the main body 1, and two second main body walls 12 each arranged along an extension direction (e.g., the first direction X) of the main body 1, and the two second main body walls 12 are respectively connected to two ends of the first main body wall 11 along the width direction (e.g., the second direction Y) of the main body 1 to form a top-opened beam-avoiding slot 13 between the first main body wall 11 and the two second main body walls 12.

[0234] It is worth noting that the width direction (e.g., the second direction Y) of the main body 1 is consistent with the width direction of the beam 20, such as the left-right direction of the vehicle 1000. The first main body wall 11 is arranged along the width direction (e.g., the second direction Y) of the main body 1, which means that the length direction of the first main body wall 11 is consistent with the width direction (e.g., the second direction Y) of the main body 1. The second main body wall 12 is arranged along the extension direction (e.g., the first direction X) of the main body 1, which means that the length direction of the second main body wall 12 is consistent with the extension direction (e.g., the first direction X) of the main body 1.

[0235] Therefore, the beam-avoiding slot 13 can be defined by the first main body wall 11 and the two second main body walls 12, which facilitates reducing the difficulty of forming the beam-avoiding slot 13, and the two second main body walls 12 are respectively connected to the two ends of the first main body wall 11 along the width direction, which facilitates defining an opening through the main body 1 along the length direction. Moreover, since the top of the beam-avoiding slot 13 is open, the main body 1 can be pushed upward from bottom to top, so that the beam 20 enters the beam-avoiding slot 13, thereby facilitating reducing the assembly difficulty of the battery mounting rack 10 to the beam 20, and the battery mounting rack 10 can be installed to the beam 20 after the beam 20 is assembled, so that the battery mounting rack 10 can be applied to various vehicle models. The present application is not limited thereto, for example, in other embodiments of the present application, the beam-avoiding slot 13 can also be provided as a bottom-opened slot, and at this time, the assembly of the battery mounting rack 10 and the beam 20 can be simultaneously performed in the process of assembling the beam 20.

[0236] Exemplarily, in combination with Figure 4 The first main body wall 11 can be connected between the lower ends of the two second main body walls 12, so that the beam-avoiding slot 13 is located above the first main body wall 11, so that the height dimension of the top-opened beam-avoiding slot 13 is larger, and the beam 20 can be accommodated to a greater extent, thereby improving the compactness of the main body 1 and the beam 20 and reducing space waste.

[0237] Exemplarily, at least one of the first main body wall 11 and the second main body wall 12 can be fixedly connected to the beam 20 by screws or other fasteners, thereby meeting the requirement of installing the main body 1 to the beam 20.

[0238] In some embodiments, please refer toFigure 5 The extension 2 is connected to the second body wall 12. In this way, the connection difficulty of the extension 2 and the main body 1 can be reduced, and the two second body walls 12 can be used to connect the extension 2, so that the extension 2 can be located on both sides of the width direction of the vehicle beam 20, and the battery 30 can be arranged in the width direction of the vehicle beam 20, so as to increase the size or the number of the battery 30.

[0239] In some embodiments, referring to Figure 8 The first body wall 11 and / or the second body wall 12 is provided with a second weight-reducing structure 14. For example, the second weight-reducing structure 14 can include but is not limited to a weight-reducing hole, or a weight-reducing groove, or a thinning treatment, etc.

[0240] In this way, the second weight-reducing structure 14 can be arranged on the first body wall 11 and / or the second body wall 12, which is conducive to reducing the weight of the first body wall 11 and / or the second body wall 12, and further conducive to realizing the lightweight design of the battery mounting rack 10.

[0241] In some embodiments, referring to Figure 8 The first body wall 11 is also provided with at least one mounting structure 3. It should be noted that the battery 30 can be mounted only on the mounting structure 3 on the extension 2, or only on the mounting structure 3 on the first body wall 11, or on the mounting structure 3 on the extension 2 and the mounting structure 3 on the first body wall 11 at the same time.

[0242] In this way, by arranging the mounting structure 3 on the first body wall 11, the installation space at the first body wall 11 can be fully utilized to improve the space utilization rate, and the number of mounting points of the mounted battery 30 or the number of mountable batteries 30 can be increased.

[0243] In some embodiments, the first body wall 11 and the two second body walls 12 are integrally formed. In this way, the first body wall 11 and the two second body walls 12 can be configured as an integrally formed structure, so as to facilitate the reduction of production procedures and further reduce production costs. Of course, it is not limited to this, and the first body wall 11 and the second body wall 12 can also be arranged as a split structure and assembled in connection, and the structural reliability is improved.

[0244] In some embodiments, the main body 1 and the extension 2 are integrally formed. In this way, the main body 1 and the extension 2 can be configured as an integrally formed structure, so as to facilitate the reduction of production procedures and further reduce production costs. Of course, it is not limited to this, and the main body 1 and the extension 2 can also be arranged as a split structure and assembled in connection, and the structural reliability is improved.

[0245] In the second aspect, referring to Figure 4The application provides a vehicle frame assembly 100, which comprises a vehicle beam 20 and a battery mounting rack 10 according to any one of the above embodiments, and the battery mounting rack 10 is used for mounting a battery 30 to the vehicle beam 20.

[0246] Therefore, when the battery 30 is mounted to the vehicle beam 20 through the battery mounting rack 10, the mounting space of the battery 30 can be expanded, so that a battery 30 with a larger size can be mounted on the battery mounting rack 10, and the single-time battery replacement mileage of the vehicle 1000 is improved.

[0247] In a third aspect, the application provides a vehicle frame assembly, which comprises a vehicle beam 20 and an extension 2. It should be noted that, compared with the vehicle frame assembly 100 of the second aspect, the vehicle frame assembly of the third aspect can not comprise the main body 1 for connecting to the vehicle beam 20, or can comprise the main body 1 for connecting to the vehicle beam 20, but the shape of the main body 1 is not limited, for example, the main body 1 can extend along the length direction (for example, the first direction X) of the vehicle beam 20, or the main body 1 can not extend along the length direction (for example, the first direction X) of the vehicle beam 20, and the shape of the main body 1 can be flexibly designed according to actual needs.

[0248] In some embodiments, as shown in FIGS. 1-3, at least part of the extension 2 is located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y), and the part of the extension 2 located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y) extends at an angle to the length direction (for example, the first direction X) of the vehicle beam 20 and extends away from the vehicle beam 20, and the part of the extension 2 located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y) is provided with a mounting structure 3 for mounting the battery 30. Figure 3 Figure 4 In some embodiments, as shown in FIGS. 1-3, at least part of the extension 2 is located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y), and the part of the extension 2 located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y) extends at an angle to the length direction (for example, the first direction X) of the vehicle beam 20 and extends away from the vehicle beam 20, and the part of the extension 2 located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y) is provided with a mounting structure 3 for mounting the battery 30.

[0249] In some embodiments, as shown in FIGS. 1-3, at least part of the extension 2 is located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y), and the part of the extension 2 located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y) extends at an angle to the length direction (for example, the first direction X) of the vehicle beam 20 and extends away from the vehicle beam 20, and the part of the extension 2 located on one side of the vehicle beam 20 in the width direction (for example, the second direction Y) is provided with a mounting structure 3 for mounting the battery 30.

[0250] ​In this way, the extension part 2 and the battery 30 can be arranged along the length direction of the vehicle 1000, for example, the extension part 2 can be located at the front side and / or the rear side of the battery 30, the extension part 2 and the mounting structure 3 arranged on the extension part 2 occupy the space of the battery 30 other than the battery 30 in the length direction of the vehicle 1000, for example, occupy the space of the front side and / or the rear side of the battery 30, without occupying the space of the battery 30 other than the battery 30 in the width direction of the vehicle 1000, for example, without occupying the space of the left and right sides of the battery 30, thereby facilitating the increase of the size of the battery 30 in the width direction of the vehicle, for example, facilitating the increase of the size of the battery 30 in the left-right direction.

[0251] It can be understood that the length of the vehicle 1000 is greater than the width of the vehicle 1000, and the length direction of the vehicle 1000 has a larger accommodation space, while the accommodation space in the width direction of the vehicle 1000 is limited. By arranging the extension part 2 and the mounting structure 3 on the front and rear sides of the battery 30 where the space is relatively sufficient, the extension part 2 and the mounting structure 3 can be avoided to occupy the space of the left and right sides of the battery 30, thereby the size of the battery 30 can be increased by using the saved space in the left-right direction, so as to improve the size-energy density of the battery 30.

[0252] Moreover, compared with the scheme of arranging the mounting structure on the two side walls of the vehicle beam, since the part of the extension part 2 of some embodiments of the present application located on one side of the width direction (such as the second direction Y) of the vehicle beam 20 is at an angle with the length direction (such as the first direction X) of the vehicle beam 20, so that the extension part 2 can have relatively sufficient space to arrange the mounting structure 3, so as to flexibly arrange the distribution position, quantity and structure form of the mounting structure 3 on the extension part 2, thereby facilitating the improvement of the mounting strength of the battery 30 mounted on the mounting structure 3, improving the mounting reliability of the battery 30, thereby facilitating the improvement of the single battery replacement mileage of the vehicle 1000.

[0253] Among them, the structure of the mounting structure 3 is not limited, for example, can include but is not limited to mounting slot, or mounting hole, or mounting protrusion, or mounting pin, or mounting screw, etc., which is not limited here.

[0254] In some embodiments, please refer to Figure 3 and Figure 4 , the extension part 2 on at least one side of the width direction (such as the second direction Y) of the vehicle beam 20 is configured to be multiple and arranged in the length direction (such as the first direction X) of the vehicle beam 20, and the battery mounting space 4 is defined between two adjacent extension parts 2 in the length direction (such as the first direction X) of the vehicle beam 20.

[0255] At least one side of the vehicle beam 20 in the width direction (e.g., the second direction Y) is provided with a plurality of extension portions 2, and the plurality of extension portions 2 on the same side of the vehicle beam 20 in the width direction (e.g., the second direction Y) are arranged at intervals in the length direction (e.g., the first direction X) of the vehicle beam 20. It should be noted that the width direction (e.g., the second direction Y) of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. Therefore, at least one of the left side and the right side of the vehicle beam 20 can be provided with a plurality of extension portions 2 arranged at intervals in the front-rear direction.

[0256] It can be understood that the mounting structure 3 on the extension portion 2 is used to mount the battery 30 in the battery mounting space 4, that is, when the battery 30 is connected to the mounting structure 3, at least part of the battery 30 can be accommodated in the battery mounting space 4, and the mounting state is presented.

[0257] In the above technical solution, the two adjacent extension portions 2 in the length direction (e.g., the first direction X) of the vehicle beam 20 can act as the outer wall of the battery mounting space 4 to protect the battery 30 to some extent, thereby reducing the damage of the battery 30 and improving the reliability of the battery 30 providing power for the vehicle 1000.

[0258] In addition, since the extension portion 2 is configured as a plurality of and arranged at intervals in the length direction (e.g., the first direction X) of the vehicle beam 20, it is beneficial to fully utilize the space in the length direction of the vehicle 1000 to arrange more extension portions 2, so as to define more battery mounting spaces 4, thereby mounting more batteries 30, so as to increase the mounting number of the battery 30 while increasing the size of the battery 30, and further improve the single battery replacement mileage of the vehicle 1000.

[0259] For example, referring again to Figure 3 and Figure 4 , four extension portions 2 are provided on one side of the vehicle beam 20 in the width direction, the four extension portions 2 are arranged at intervals in the length direction (e.g., the first direction X) of the vehicle beam 20, and the four extension portions 2 define three battery mounting spaces 4, each of which can mount at least one battery 30, and when the battery 30 is mounted on the mounting structure 3, at least part of the battery 30 is located in the battery mounting space 4. At this time, the two adjacent extension portions 2 can act as the outer wall of the battery mounting space 4 to protect the battery 30 to some extent, thereby reducing the damage of the battery 30 and improving the reliability of the battery 30 providing power for the vehicle 1000.

[0260] Of course, the number of extension portions 2 described above is only used for illustration, for example, the extension portions 2 on one side of the vehicle beam 20 can also be provided with three, or five, or more, etc., which can be set according to the specific needs of the vehicle 1000.

[0261] When the battery mounting rack 10 includes multiple battery mounting spaces 4, the extension 2 between two battery mounting spaces 4 can be used to isolate the batteries 30 in the two adjacent battery mounting spaces 4, thereby improving the mutual knocking and heat transfer of the batteries 30 in the two adjacent battery mounting spaces 4. Of course, the battery mounting rack 10 can also include only one battery mounting space 4.

[0262] In some embodiments, the battery mounting space 4 is through in the height direction (such as the third direction Z) of the vehicle beam 20. Here, the "battery mounting space 4 is through in the height direction of the vehicle beam 20" means that the two ends of the battery mounting space 4 in the height direction of the vehicle beam 20 are open, and there is no structure on the battery mounting rack 10 to block. Here, the height direction of the vehicle beam 20 is consistent with the height direction of the vehicle 1000.

[0263] Therefore, when the battery 30 is mounted in the battery mounting space 4, the battery 30 can be free from the obstruction of the battery mounting rack 10 in the height direction of the vehicle 1000, such as the extension 2, the main body 1, and the mounting structure 3, and the like. The space occupied by the battery 30 in the height direction of the vehicle 1000 is thus improved, thereby improving the space utilization of the battery 30 in the height direction of the vehicle 1000, facilitating the increase of the size of the battery 30 in the height direction of the vehicle 1000, and facilitating the increase of the size energy density of the battery 30, thereby improving the single battery replacement mileage of the vehicle 1000 and ensuring the ground clearance of the battery 30 and the passability of the vehicle 1000. Moreover, it is also beneficial to the heat dissipation of the battery 30. Furthermore, it is also beneficial to reduce the weight of the battery mounting rack 10 and the vehicle load of the battery mounting rack 10.

[0264] Some vehicles in the related art generally use a tray to install a battery pack at the bottom of the vehicle, that is, the battery pack is placed on the tray, and then the tray is installed at the bottom of the vehicle. When it is necessary to replace the battery, the entire battery pack in the tray is replaced, and then the tray is installed back at the bottom of the vehicle. However, when the battery is replaced, the energy of the battery pack in the tray is usually not fully used, and at this time, the replacement of the battery causes energy waste.

[0265] In the embodiments of the present application, the battery mounting rack 10 includes multiple battery mounting spaces 4 arranged in sequence in the length direction (such as the first direction X) of the vehicle beam 20. The battery mounting rack 10 includes multiple battery mounting spaces 4, and the battery mounting rack 10 is provided with a mounting structure 3 corresponding to each battery mounting space 4, so that each battery mounting space 4 can be used to mount a battery 30. The mounting structures 3 corresponding to different battery mounting spaces 4 can be independent of each other, so that each battery mounting space 4 can individually replace the mounted battery 30. Here, the "corresponding" of the mounting structure 3 to the battery mounting space 4 refers to the correspondence in the relationship, including but not limited to the correspondence in the position.

[0266] But not limited to, for example, in some embodiments, when multiple battery mounting spaces 4 are used to mount the same battery 30, for example, two battery mounting spaces 4 corresponding to the arrangement along the second direction Y are used to mount the same battery 30, the mounting structure 3 corresponding to the two battery mounting spaces 4 respectively can be arranged independently, or can also be arranged in the form of linkage, so that when mounting the same battery 30, the mounting structure 3 in the form of linkage is beneficial to improve the battery replacement efficiency.

[0267] It can be understood that when the size of the battery 30 is large, the same battery 30 can be installed in multiple battery mounting spaces 4 at the same time, and when the size of the battery 30 is small, one battery 30 can be arranged corresponding to one battery mounting space 4, or multiple batteries 30 can be arranged corresponding to one battery mounting space 4, that is, the specific mounting method depends on the form of the battery 30, which is not limited here.

[0268] When the battery 30 is installed on the vehicle using such a battery mounting rack 10, since the battery mounting rack 10 includes multiple battery mounting spaces 4, and the mounting structure 3 is arranged on the battery mounting rack 10 so that each battery mounting space 4 can be used to mount the battery 30, each battery mounting space 4 can be individually mounted with the battery 30, so that the battery mounting rack 10 can have the function of installing multiple batteries 30, when replacing the battery, only the battery 30 with the exhausted power can be replaced, while the battery 30 with the unexhausted power is retained, so that the energy utilization rate of the battery 30 can be improved, and the energy waste problem can be improved.

[0269] In some embodiments, please refer to Figures 4-6 , Figure 5 is Figure 4 a partial enlarged view of part A in FIG. 8, Figure 6 is Figure 4 a connection front projection view of the battery mounting rack 10 and the vehicle beam 20, the side of the extension part 2 facing the battery mounting space 4 is arranged with the mounting structure 3. That is, the extension part 2 includes a mounting surface 23 facing the battery mounting space 4, and the mounting structure 3 is arranged on the side of the mounting surface 23 facing the battery mounting space 4.

[0270] In this way, the mounting structure 3 is arranged towards which battery mounting space 4 corresponds, for mounting the battery 30 to the battery mounting space 4 towards which the mounting structure 3 is arranged, so that the correspondence between the mounting structure 3 and the battery mounting space 4 can be clear, and the battery 30 can be conveniently mounted by being inserted into the battery mounting space 4 and connected to the mounting structure 3 arranged towards the battery mounting space 4. Moreover, when there are multiple battery mounting spaces 4, the mounting structures 3 arranged corresponding to different battery mounting spaces 4 are arranged at different positions and do not interfere with each other, so that the mounting structure 3 corresponding to each battery mounting space 4 can be arranged flexibly in sufficient space, so that the battery 30 can be more easily and reliably mounted by the mounting structure 3. Therefore, by arranging the mounting structure 3 on the side of the extension 2 towards the battery mounting space 4, the arrangement difficulty of the mounting structure 3 can be reduced, and the mounting structure 3 can be arranged flexibly in sufficient space, so that the battery 30 can be more easily and reliably mounted by the mounting structure 3.

[0271] In some embodiments, referring again to Figures 4-6 , at least one of the extensions 2 in the middle of the multiple extensions 2 is a shared extension 2a, the shared extension 2a has battery mounting spaces 4 on both sides in the length direction (such as the first direction X) of the vehicle beam 20, and the mounting structure 3 is arranged on both sides of the shared extension 2a towards the battery mounting spaces 4 on both sides.

[0272] It is worth noting that "at least one of the extensions 2 in the middle of the multiple extensions 2" refers to at least one of the extensions 2 in the middle of the multiple extensions 2 arranged at intervals in the length direction (such as the first direction X) of the vehicle beam 20, except for the two extensions 2 on both sides. For example, when there are four extensions 2 on one side of the width of the vehicle beam 20, at least one of the two extensions 2 in the middle is a shared extension 2a. The shared extension 2a has two mounting surfaces 23 respectively towards the battery mounting spaces 4 on both sides.

[0273] Therefore, when the number of battery mounting spaces 4 arranged at intervals in the length direction (such as the first direction X) of the vehicle beam 20 is fixed, the number of extensions 2 arranged at intervals in the length direction (such as the first direction X) of the vehicle beam 20 can be reduced, for example, in the worst case, the number of extensions 2 on one side of the width of the vehicle beam 20 can be one more than the number of battery mounting spaces 4, that is, only one extension 2 is arranged between two adjacent battery mounting spaces 4 in the length direction (such as the first direction X) of the vehicle beam 20, thereby facilitating cost reduction and load reduction of the vehicle 1000.

[0274] However, the application is not limited thereto, for example, two extension portions 2 can be arranged between two adjacent battery mounting spaces 4 along the length direction (e.g., the first direction X) of the vehicle beam 20, so that each extension portion 2 can be arranged with the mounting structure 3 corresponding to only one side of the battery mounting space 4, thereby reducing the bearing force of each extension portion 2 on the battery and improving the mounting reliability of the battery 30.

[0275] In some embodiments, referring again to Figures 4-6 , the mounting structures 3 on both sides of the shared extension portion 2a in the length direction (e.g., the first direction X) of the vehicle beam 20 are misaligned in the orthographic projection on the projection plane perpendicular to the length direction (e.g., the first direction X) of the vehicle beam 20. That is, the orthographic projections of the mounting structures 3 on the two mounting installation surfaces 23 of the shared extension portion 2a along the length direction (e.g., the first direction X) of the vehicle beam 20 are misaligned. For example, the distance from any mounting structure 3 on one side of the shared extension portion 2a to the vehicle beam 20 in the width direction (e.g., the second direction Y) of the vehicle beam 20 is different from the distance from any mounting structure 3 on the other side of the shared extension portion 2a to the vehicle beam 20 in the width direction (e.g., the second direction Y) of the vehicle beam 20.

[0276] Therefore, by misaligning the orthographic projections of the mounting structures 3 on both sides of the shared extension portion 2a in the projection plane perpendicular to the length direction (e.g., the first direction X) of the vehicle beam 20, the stress distribution of the shared extension portion 2a is more reasonable, and when the batteries 30 in the battery mounting spaces 4 on both sides of the shared extension portion 2a are connected to the mounting structures 3 on both sides of the shared extension portion 2a, respectively, the stress concentration is reduced, and problems such as deformation and fracture of the extension portion 2 are avoided, the service life of the shared extension portion 2a is improved, and the mounting reliability of the battery 30 is improved.

[0277] In some embodiments, referring again to Figures 4-6 , the mounting structures 3 are arranged on both sides of the extension portion 2 in the length direction (e.g., the first direction X) of the vehicle beam 20. For example, the mounting installation surface 23 includes a first mounting installation surface 231 and a second mounting installation surface 232, the first mounting installation surface 231 and the second mounting installation surface 232 are respectively one side surface of two adjacent extension portions 2 facing the same battery mounting space 4, the side of the first mounting installation surface 231 facing the battery mounting space 4 is provided with a mounting structure 3, and the side of the second mounting installation surface 232 facing the battery mounting space 4 is also provided with a mounting structure 3, and the battery 30 in the battery mounting space 4 is connected to the two mounting structures 3, respectively.

[0278] Therefore, the extension portions 2 on both sides of the battery mounting space 4 in the length direction (such as the first direction X) of the vehicle beam 20 can bear the battery 30 in the battery mounting space 4, and the mounting structures 3 on both sides can disperse the stress to reduce stress concentration and deformation, fracture and other problems of the extension portions 2, improve the service life of the shared extension portion 2a, and improve the mounting reliability of the battery 30.

[0279] Further, in some embodiments, the mounting structures 3 on both sides of the battery mounting space 4 in the length direction (such as the first direction X) of the vehicle beam 20 are offset in the orthographic projection on the projection plane perpendicular to the length direction (such as the first direction X) of the vehicle beam 20. For example, the distance from any mounting structure 3 on one side of the battery mounting space 4 to the vehicle beam 20 in the width direction (such as the second direction Y) of the vehicle beam 20 is different from the distance from any mounting structure 3 on the other side of the battery mounting space 4 to the vehicle beam 20 in the width direction (such as the second direction Y) of the vehicle beam 20.

[0280] Therefore, by setting the mounting structures 3 on both sides of the battery mounting space 4 to be offset in the orthographic projection on the projection plane perpendicular to the length direction (such as the first direction X) of the vehicle beam 20, the mounting structures 3 on both sides can further disperse the stress, and further improve the problems of deformation, fracture and the like caused by stress concentration.

[0281] In addition, when the mounting structures 3 on both sides of the shared extension portion 2a in the length direction (such as the first direction X) of the vehicle beam 20 are offset in the orthographic projection on the projection plane perpendicular to the length direction (such as the first direction X) of the vehicle beam 20, and the mounting structures 3 on both sides of the battery mounting space 4 in the length direction (such as the first direction X) of the vehicle beam 20 are offset in the orthographic projection on the projection plane perpendicular to the length direction (such as the first direction X) of the vehicle beam 20, the multiple extension portions 2 can be constructed as the same structure to reduce costs and production processes.

[0282] Of course, the present application is not limited thereto, for example, the mounting structures 3 on both sides of the shared extension portion 2a in the length direction (such as the first direction X) of the vehicle beam 20 can also be set to coincide in the orthographic projection on the projection plane perpendicular to the length direction (such as the first direction X) of the vehicle beam 20, and at this time, the mounting structures 3 on both sides of the battery mounting space 4 in the length direction (such as the first direction X) of the vehicle beam 20 can also coincide in the orthographic projection on the projection plane perpendicular to the length direction (such as the first direction X) of the vehicle beam 20, thereby simplifying the processing and reducing the cost.

[0283] In some embodiments, please refer to Figure 4 and Figure 5 The side of the extension portion 2 facing the battery mounting space 4 is provided with multiple mounting structures 3, and at least two of the mounting structures 3 are arranged in the width direction (such as the second direction Y) of the vehicle beam 20.

[0284] In this way, it is beneficial to make full use of the space in the width direction (e.g., the second direction Y) of the vehicle beam 20 to arrange a larger number of the mounting structures 3, thereby facilitating the enhancement of the mounting stability of the battery 30 or the increase of the number of the batteries 30 mounted in the battery mounting space 4.

[0285] In some embodiments, referring to Figure 5 , the extension part 2 comprises a mounting edge 24 protruding towards the inside of the battery mounting space 4, and the mounting structure 3 is located on the mounting edge 24. For example, the mounting edge 24 protrudes towards the inside of the battery mounting space 4 along the length direction (e.g., the first direction X) of the vehicle beam 20.

[0286] In this way, by providing the mounting edge 24, it is beneficial to reduce the difficulty of arranging the mounting structure 3, and it is easy to realize that the mounting structure 3 is located on the side of the extension part 2 facing the battery mounting space 4, and the mounting edge 24 can directly or indirectly support the battery 30 to some extent, thereby enhancing the mounting stability of the battery 30.

[0287] In some embodiments, referring to Figure 4 and Figure 5 , the mounting edge 24 is located at the lower edge of the extension part 2 in the height direction (e.g., the third direction Z) of the vehicle beam 20. The height direction (e.g., the third direction Z) of the vehicle beam 20 is consistent with the height direction of the vehicle 1000, i.e., the direction of gravity.

[0288] In this way, the mounting structure 3 is arranged at a low height, which is beneficial to reduce the difficulty of maintaining the mounting structure 3, and is beneficial to the loading connection between the mounting structure 3 and the battery 30, and improves the compactness of the cooperation between the battery 30 and the extension part 2, reduces the space waste, and further increases the size of the battery 30 by saving space, thereby further improving the size energy density of the battery 30.

[0289] For example, when a tool is used to extend upwards to the position of the mounting structure 3 to perform the mounting connection between the mounting structure 3 and the battery 30, the tool is lifted to a position lower than the extension part 2, thereby reducing the lifting height of the tool, and the tool does not need to extend into the space between the battery 30 and the extension part 2, and the gap between the battery 30 and the extension part 2 does not need to be increased to meet the extension requirement of the tool, thereby reducing the space waste, further increasing the size of the battery 30 by saving space, and further improving the size energy density of the battery 30.

[0290] In some embodiments, referring to Figure 4 and Figure 5 , the length direction of the mounting edge 24 is the same as the width direction (e.g., the second direction Y) of the vehicle beam 20, and a plurality of mounting structures 3 are arranged on the mounting edge 24 in the length direction of the mounting edge 24.

[0291] Therefore, since the length direction of the mounting edge 24 is the same as the width direction (e.g., the second direction Y) of the vehicle beam 20, the processing difficulty of the mounting edge 24 is reduced, the mounting edge 24 has a larger length dimension, and a larger number of mounting structures 3 are arranged along the length direction of the mounting edge 24, thereby improving the mounting stability of the battery 30 or increasing the number of batteries 30 mounted on the mounting edge 24.

[0292] In some embodiments, referring to Figure 7 , Figure 7 FIG. 8 is a partial enlarged view of the battery mounting rack 10 according to another embodiment of the present application. The length direction of the mounting edge 24 is the same as the width direction (e.g., the second direction Y) of the vehicle beam 20, and the mounting structure 3 on the mounting edge 24 is configured as one and extends along the length direction of the mounting edge 24.

[0293] Therefore, by arranging only one mounting structure 3 on the mounting edge 24, the processing difficulty of the mounting structure 3 is reduced, and the mounting structure 3 extends along the length direction of the mounting edge 24, i.e., the length direction of the mounting structure 3 is consistent with the length direction of the mounting edge 24, thereby increasing the size of the mounting structure 3, increasing the force receiving area, or increasing the number of connection positions to facilitate connection with multiple connection structures on the battery 30, thereby improving the mounting reliability of the battery 30 or facilitating mounting of multiple batteries 30.

[0294] In some embodiments, one side of the vehicle beam 20 in the width direction (e.g., the second direction Y) is provided with an extension 2. It should be noted that the width direction (e.g., the second direction Y) of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, e.g., the left-right direction of the vehicle 1000. For example, the left side of the vehicle beam 20 is provided with the extension 2, or the right side of the vehicle beam 20 is provided with the extension 2.

[0295] Therefore, by arranging the extension 2 on only one side of the vehicle beam 20 in the width direction (e.g., the second direction Y), the force transmitted from the extension 2 with the mounted battery 30 to the vehicle beam 20 is reduced, thereby improving the connection reliability of the extension 2 and the vehicle beam 20 and improving the connection reliability of the vehicle beam 20, thereby improving the mounting reliability of the battery 30.

[0296] In some embodiments, referring to Figure 3 and Figure 4The extension 2 is arranged on each of the two sides in the width direction (e.g., the second direction Y) of the vehicle beam 20. That is, the extension 2 is arranged on the vehicle beam 20 in multiple numbers, and at least two of the multiple extensions 2 are arranged on each of the two sides in the width direction (e.g., the second direction Y) of the vehicle beam 20. It is to be noted that the width direction (e.g., the second direction Y) of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, e.g., the left-right direction of the vehicle 1000. For example, the left side of the vehicle beam 20 is provided with an extension 2, and the right side of the vehicle beam 20 is also provided with an extension 2.

[0297] In this way, by arranging the extension 2 on each of the two sides in the width direction (e.g., the second direction Y) of the vehicle beam 20, the two sides of the vehicle beam 20 can be used to mount the battery 30 respectively, e.g., two parts of the same battery 30 on the two sides in the width direction of the vehicle beam 20 can be mounted respectively, or two batteries 30 on the two sides in the width direction of the vehicle beam 20 can be mounted respectively, so that the mounting strength of the battery 30 can be increased, or the number of batteries 30 mounted can be increased.

[0298] In some embodiments, referring to Figure 3 and Figure 4 The extension 2 includes a first extension 21 and a second extension 22 arranged on each of the two sides in the width direction (e.g., the second direction Y) of the vehicle beam 20 respectively, the extension directions of the first extension 21 and the second extension 22 are the same, and the first extension 21 and the second extension 22 are projected to coincide in the extension direction of the first extension 21.

[0299] It is to be noted that the width direction (e.g., the second direction Y) of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, e.g., the left-right direction of the vehicle 1000. For example, the first extension 21 and the second extension 22 extend in the width direction (e.g., the second direction Y) of the vehicle beam 20, or the first extension 21 and the second extension 22 extend in directions oblique to the width direction of the vehicle beam 20, and the oblique angles are the same.

[0300] In this way, by arranging the extension directions of the first extension 21 and the second extension 22 to be the same, and by projecting the first extension 21 and the second extension 22 to coincide in the extension direction of the first extension 21, the first extension 21 and the second extension 22 can be used to mount two parts of the same battery 30 on the two sides in the width direction of the vehicle beam 20 simultaneously, so that the size of the battery 30 can be larger, and the number of batteries 30 can be reduced, and the complexity of battery replacement can be reduced.

[0301] In some embodiments, referring to Figure 3 and Figure 4When at least one side of the vehicle beam 20 in the width direction (e.g., the second direction Y) is provided with multiple extension portions 2 arranged at intervals along the length direction (e.g., the first direction X) of the vehicle beam 20, the battery mounting rack 10 further comprises a reinforcing portion 5 for connecting at least two extension portions 2 located on the same side of the vehicle beam 20 in the width direction (e.g., the second direction Y). It is worth noting that the present embodiment is applicable to both the case of "arranging at least one extension portion 2 on each of the two sides of the vehicle beam 20 in the width direction" and the case of "arranging extension portions 2 on one side of the vehicle beam 20 in the width direction". In addition, the at least two extension portions 2 connected by the reinforcing portion 5 can be adjacent or non-adjacent.

[0302] Furthermore, it is worth noting that the width direction of the vehicle beam 20 (e.g., the second direction Y) coincides with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. For example, at least two extension portions 2 on the left side of the vehicle beam 20 are connected by the reinforcing portion 5, and / or at least two extension portions 2 on the right side of the vehicle beam 20 are connected by the reinforcing portion 5.

[0303] In this way, the overall structural strength of the battery mounting rack 10 is enhanced, the deformation of the extension portion 2 caused by stress is reduced, and the mounting reliability of the battery 30 is improved.

[0304] In some embodiments, the reinforcing portion 5 and the main body portion 1 are located on both sides of the extension portion 2 in the width direction (e.g., the second direction Y) of the vehicle beam 20. In this way, the two extension portions 2 defining the battery mounting space 4 on both ends in the width direction (e.g., the second direction Y) of the vehicle beam 20 can be connected by the main body portion 1 and the reinforcing portion 5, respectively. In this way, the structure around the battery mounting space 4 is formed in a ring shape, which has higher structural strength, higher mounting reliability for the battery 30, and can more comprehensively protect the battery 30 from the side, and the position of the mounting structure 3 can be flexibly selected.

[0305] In some embodiments, please refer to Figure 5 , the height of the extension portion 2 in the height direction (e.g., the third direction Z) of the vehicle beam 20 decreases along the direction away from the vehicle beam 20. It is worth noting that "decreases" can be gradually reduced or stepwise reduced.

[0306] In this way, by arranging the height of the extension portion 2 to decrease along the direction away from the vehicle beam 20, the height of the area of the extension portion 2 away from the vehicle beam 20 is smaller, that is, the height of the end of the extension portion 2 connected to the vehicle beam 20 is relatively large, while the height of the end of the extension portion 2 away from the vehicle beam 20 is relatively small, thereby enhancing the connection strength of the extension portion 2 and the vehicle beam 20, improving the mounting reliability of the extension portion 2 for the battery 30, and reducing the weight of the extension portion 2 and the load of the vehicle 1000.

[0307] When the mounting structure 3 is located at the lower edge of the extension 2 in the height direction (such as the third direction Z) of the vehicle beam 20, for example, provided on the mounting edge 24, and the mounting edge 24 is located at the lower edge position of the extension 2, the lower edge of the extension 2 can be arranged to extend horizontally, and the upper edge of the extension 2 in the height direction (such as the third direction Z) of the vehicle beam 20 is lowered in the direction away from the vehicle beam 20. It is worth noting that "lowered" can be gradually lowered or stepped lowered. Thus, it is beneficial to mount the mounting structure 3 at the same horizontal height, thereby facilitating the mounting operation of the battery 30.

[0308] In some embodiments, in combination with Figure 7 As shown, the extension 2 is further provided with a reinforcing rib 25. The structure of the reinforcing rib 25 is not limited, for example, it can be linear, or curved, or cross-shaped, etc. Thus, by providing the reinforcing rib 25, the structural strength of the extension 2 is improved, and the problem of stress deformation of the extension 2 is improved.

[0309] For example, generally, the farther the extension 2 is from the body portion 1, the more likely it is to deform. At least part of the reinforcing rib 25 can be arranged near the middle of the extension 2 in the width direction (such as the second direction Y) of the vehicle beam 20, that is, in the overall central or substantially central position, for example, in the position range between 1 / 3-2 / 3 of the extension 2 in the width direction (such as the second direction Y) of the vehicle beam 20. In this way, the number of reinforcing ribs 25 can be reduced, and the structural strength of the extension 2 can be improved, and the mounting reliability of the extension 2 for the battery 30 can be improved.

[0310] For example, when the mounting structure 3 of the extension 2 mounts the battery 30, the mounting structure 3 of the extension 2 is stressed and deformed, and thus at least part of the reinforcing rib 25 can be arranged corresponding to the mounting structure 3 in the height direction (such as the third direction Z) of the vehicle beam 20. In this way, the number of reinforcing ribs 25 can be reduced, and the structural strength of the extension 2 can be improved, and the mounting reliability of the extension 2 for the battery 30 can be improved.

[0311] For example, when the extension 2 is provided with a plurality of mounting structures 3, at least part of the reinforcing rib 25 can be arranged corresponding to the adjacent two mounting structures 3 in the height direction (such as the third direction Z) of the vehicle beam 20. When the mounting structure 3 of the extension 2 mounts the battery 30, the mounting structure 3 of the extension 2 is stressed and deformed, and thus at least part of the reinforcing rib 25 can be arranged corresponding to the adjacent two mounting structures 3. In this way, the structural strength of the extension 2 between the adjacent two mounting structures 3 can be improved, the problem of stress concentration and fracture between the adjacent two mounting structures 3 can be improved, and the mounting reliability of the extension 2 for the battery 30 can be improved.

[0312] In some embodiments, please refer to Figure 5 The extension 2 is provided with a first weight-reducing structure 26. For example, the first weight-reducing structure 26 may include, but is not limited to, weight-reducing holes, weight-reducing grooves, or thinning treatment.

[0313] In this way, by setting the first weight reduction structure 26, the weight of the extension 2 is reduced, thereby facilitating the lightweight design of the battery mounting bracket 10.

[0314] In some embodiments, the extension 2 is located on one side of the beam 20 in the width direction (such as the second direction Y), and the frame assembly 100 further includes a main body 1 connected to the beam 20, and the extension 2 connected to the main body 1.

[0315] Therefore, by setting the main body 1, the extension 2 can be connected to the vehicle beam 20 through the main body 1, which reduces the difficulty of setting the extension 2. Moreover, by setting the extension 2 on one side of the width direction (such as the second direction Y) of the vehicle beam 20, the space in the width direction of the vehicle beam 20 can be fully utilized to mount the battery 30, thereby increasing the size of the battery 30. In addition, when multiple extensions 2 are set, for example, multiple extensions 2 can be set on the main body 1 first, and then the main body 1 can be connected to the vehicle beam 20. This simplifies the assembly steps and reduces the assembly difficulty. Furthermore, when setting extensions 2 on vehicle beams 20 of different sizes, only the main body 1 needs to be adjusted, which enhances the adaptability of the extension 2.

[0316] The main body 1 can be integrally formed with the extension 2 to simplify production steps and reduce production costs. Alternatively, the main body 1 and the extension 2 can be separately formed and assembled together, such as by welding or screw connection, thereby reducing the processing difficulty of each part.

[0317] In some embodiments, the main body 1 spans the beam 20, such that extensions 2 are respectively connected to both sides of the main body 1 in the width direction (such as the second direction Y) of the beam 20. "The main body 1 spans the beam 20" includes, but is not limited to, the main body 1 spanning along the width direction of the beam 20, or the main body 1 spanning along a direction intersecting with the width direction of the beam 20.

[0318] Therefore, by setting the main body 1 across the vehicle beam 20, the main body 1 can simultaneously connect the extensions 2 on both sides of the vehicle beam 20 in the width direction, thereby further improving the assembly efficiency of the battery mounting bracket 10 and the vehicle beam 20. It also helps to improve the overall structural strength of the battery mounting bracket 10. Furthermore, since the vehicle beam 20 has extensions 2 on both sides capable of mounting batteries 30, the space on both sides of the width of the vehicle beam 20 can be fully utilized to mount the batteries 30, which helps to increase the size and number of batteries 30, thereby increasing the vehicle's driving range per 1000 battery swaps.

[0319] In a fourth aspect, the present application provides a vehicle 1000, comprising a battery 30 and a frame assembly 100 according to any one of the above embodiments, wherein the battery 30 is mounted to the frame assembly 100. Thus, the size and quantity of the battery 30 can be increased by arranging the frame assembly 100 of the present application, thereby facilitating to improve the single battery swap mileage of the vehicle 1000.

[0320] In some embodiments, referring to Figure 9 and Figure 10 , the battery 30 comprises a battery upper portion 30a and a battery lower portion 30b, the battery upper portion 30a is higher than the bottom surface of the beam 20, and the battery lower portion 30b is lower than the bottom surface of the beam 20. Thus, the battery upper portion 30a can occupy the space on both sides of the width of the beam 20, thereby improving the space utilization rate, so that the size of the battery 30 in the height direction of the vehicle 1000 can be increased to improve the energy density of the battery 30. At the same time, the mounting structure 30c is detachably connected with the mounting structure 3, which facilitates to reduce the difficulty of replacing the battery 30 and improve the battery swap efficiency.

[0321] Further, in some embodiments, referring to Figure 9 and Figure 10 , the extension portion 2 can be higher than the bottom surface of the beam 20, the mounting structure 3 is arranged at the lower edge of the extension portion 2, and the mounting structure 30c is arranged at a position between the battery upper portion 30a and the battery lower portion 30b of the battery 30, and the mounting structure 30c is detachably connected with the mounting structure 3. Thus, when the battery 30 is mounted on the battery mounting rack 10, the battery upper portion 30a can extend into the battery mounting space 4, and the battery lower portion 30b is located below the battery mounting space 4. The extension portion 2 can play a certain protection role for the battery upper portion 30a, thereby reducing the damage risk of the battery 30 and facilitating to prolong the service life of the battery 30. At the same time, the height of the extension portion 2 can be less than the height of the battery 30, so that the height of the extension portion 2 can be reduced, thereby reducing the weight and cost of the battery mounting rack 10. Moreover, the mounting structure 30c is arranged at a position between the battery upper portion 30a and the battery lower portion 30b, so that the mounting structure 3 located at the lower edge of the extension portion 2 can be connected with the mounting structure 30c, thereby facilitating the battery swap operation.

[0322] In some embodiments, the connection mode of the mounting structure 30c and the mounting structure 3 includes but is not limited to bolt connection, clamping, insertion, magnetic attraction, etc.

[0323] In some embodiments, referring to Figure 9 and Figure 10In the length direction (e.g., the first direction X) of the vehicle beam 20, the size of the battery upper portion 30a is smaller than the size of the battery lower portion 30b, so as to form a stepped surface 30d between the battery upper portion 30a and the battery lower portion 30b, and the stepped surface 30d is stopped at the bottom of the extension 2.

[0324] It is worth mentioning that the stepped surface 30d is stopped at the bottom of the extension 2 as a broad sense, that is, the stepped surface 30d and the extension 2 can be in direct contact to achieve the stopping effect, or can be in indirect contact to achieve the stopping effect. For example, a mounting structure 3 can be arranged at the lower position of the extension 2, and a mounting structure 30c can be arranged on the stepped surface 30d. When the mounting structure 30c and the mounting structure 3 are connected in cooperation, the stepped surface 30d is stopped at the bottom of the extension 2.

[0325] Therefore, when the battery 30 is actually installed, the battery upper portion 30a is installed from bottom to top, and the stopping of the bottom of the extension 2 and the stepped surface 30d can prompt the assembly of the battery 30 to be in place, so as to avoid the problem that the battery 30 is excessively pressed and hits the vehicle bottom, thereby protecting the battery 30. In addition, by setting the size of the battery lower portion 30b to be larger than the size of the battery upper portion 30a, the size of the battery 30 can be further increased to a certain extent, thereby further improving the size energy density of the battery 30.

[0326] In some embodiments, please refer to Figure 11 and Figure 12 The battery 30 includes two battery side portions 30e and a battery central portion 30f. In the width direction (e.g., the second direction Y) of the vehicle beam 20, the two battery side portions 30e are respectively located on both sides of the battery central portion 30f, and the top surface of the battery central portion 30f is lower than the top surface of the battery side portion 30e, so as to form a gap slot 30g which is through in the length direction (e.g., the first direction X) of the vehicle beam 20 and open at the top between the two battery side portions 30e and the battery central portion 30f.

[0327] For example, the bottom surface of the battery central portion 30f is flush with the bottom surface of the battery side portion 30e, so that the bottom surface of the battery 30 as a whole is a planar structure, thereby facilitating the full use of space and easily designing the ground clearance of the battery 30.

[0328] Therefore, when the battery 30 is installed upward in the vehicle bottom, at least part of the vehicle beam 20 can be accommodated in the gap slot 30g and located above the battery central portion 30f, and the upper portions of the two battery side portions 30e can be respectively located on both sides in the width direction of the vehicle beam 20. In this way, the space on both sides in the width direction of the vehicle beam 20 can be fully utilized to arrange a battery 30 of larger size. Therefore, the structure of the battery 30 is ingenious, and by avoiding the vehicle beam 20 to fully utilize the space on both sides in the width direction of the vehicle beam 20, the overall size of the battery 30 can be increased, thereby improving the size energy density of the battery 30.

[0329] In some embodiments, referring to Figure 11 and Figure 12 at least one of the battery side portion 30e and the battery central portion 30f is detachably connected with the mounting structure 3. In this case, the “at least one of the battery side portion 30e and the battery central portion 30f is detachably connected with the mounting structure 3” includes that the battery side portion 30e is detachably connected with the mounting structure 3, or the battery central portion 30f is detachably connected with the mounting structure 3, or the battery side portion 30e and the battery central portion 30f are respectively detachably connected with the corresponding mounting structure 3.

[0330] In this case, the battery side portion 30e is detachably connected with the mounting structure 3 can be that the mounting structure 30c on the battery side portion 30e is detachably connected with the mounting structure 3, and the position of the mounting structure 30c on the battery side portion 30e is not limited, for example, can be located in the middle, upper or lower portion of the battery side portion 30e, etc.

[0331] In this case, the battery central portion 30f is detachably connected with the mounting structure 3 can be that the mounting structure 30c on the battery central portion 30f is detachably connected with the mounting structure 3, and the position of the mounting structure 30c on the battery central portion 30f is not limited, for example, can be located in the middle, upper or lower portion of the battery central portion 30f, etc.

[0332] In this case, the connection mode of the battery side portion 30e and / or the battery central portion 30f with the mounting structure 3 includes but is not limited to: through bolt connection, or clamping, or plug-in, or magnetic attraction, etc.

[0333] In this case, when both of the battery side portions 30e are connected with the mounting structure 3, or the battery side portion 30e and the battery central portion 30f are connected with the mounting structure 3, the installation stability of the battery 30 can be improved. In addition, detachably connecting at least one of the battery side portion 30e and the battery central portion 30f with the mounting structure 3 is conducive to improving the design flexibility of the battery 30.

[0334] It is worth noting that the form of the battery 30 of the embodiments of the present application is not limited to this, for example, can only include one battery side portion 30e, or simultaneously include the battery central portion 30f and one battery side portion 30e, etc.

[0335] In some embodiments of the present application, as shown in Figure 13 and Figure 14 For the battery mounting rack 10 of any embodiment of the present application, further comprising a docking structure 6, the docking structure 6 is used to connect the vehicle body of the vehicle 100 and the docking battery 30, so that the battery 30 and the vehicle body form a circuit and / or a liquid circuit communication.

[0336] When the battery 30 is mounted on the rack body 10a by the mounting structure 3, the battery 30 can be docked with the docking structure 6 to form a circuit and / or a liquid path communication, and the docking structure 6 has a connection relationship with the vehicle body, thereby meeting the communication requirement of the battery 30 with the circuit and / or the liquid path of the vehicle body through the docking with the docking structure 6.

[0337] It is worth noting that the connection mode of the docking structure 6 with the vehicle body is not limited, for example, the docking terminal can be used to realize the connection through the docking mode, or the connection can also be realized through the plug-in wire and / or pipe. In addition, the sum of other parts of the vehicle 1000 except the battery 30 and the battery mounting rack 10 can be understood as the vehicle body, and the vehicle beam 20 is part of the vehicle body.

[0338] For example, when the docking structure 6 is used to realize the circuit communication, it can be used for the current transmission between the vehicle 1000 and the battery 30, realizing the power supply of the vehicle 1000 by the battery 30, the control of the vehicle 1000 to the battery 30, etc. For example, when the docking structure 6 is used to realize the liquid path communication, it can be used for the heat transfer between the thermal management system of the vehicle 1000 and the battery 30, so as to adjust the temperature of the battery 30 by the thermal management system to improve the working reliability and safety of the battery 30, or the waste heat of the battery 30 can be absorbed by the thermal management system to meet the heat source requirement of the heat pump air conditioning system of the vehicle 1000, etc., which is not described here.

[0339] Therefore, by providing the docking structure 6 on the battery mounting rack 10, the communication requirement of the battery 30 with the circuit and / or the liquid path of the vehicle body can be met by the structural design of the battery mounting rack 10, so as to simplify the structural design of the vehicle body and the battery 30. It should be noted that the setting position of the docking structure 6 is not limited, which can be selected according to the form of the battery mounting rack 10.

[0340] In some embodiments, as shown in Figure 13 The mounting structure 3 is provided on the extension part 2, and the main body part 1 and the extension part 2 are connected to form the rack body 10a, so that the docking structure 6 and the mounting structure 3 are integrated on the rack body 10a. When the battery 30 is installed on the vehicle body by using such a battery mounting rack 10, the mounting and installation of the battery 30 can be realized by the mounting structure 3 integrated on the rack body 10a, and the circuit and / or liquid path communication between the battery 30 and the vehicle body can be realized by the docking structure 6 integrated on the rack body 10a, so as to simplify the cumbersome battery replacement operation and improve the battery replacement efficiency without connecting the wire and pipe. Moreover, since the mounting structure 3 and the docking structure 6 are integrated on the rack body 10a, the reference datum of the mounting connection position of the battery 30 and the water and electricity docking position is consistent, that is, the reference datum is the rack body 10a, so as to improve the battery replacement success rate.

[0341] In some embodiments, the docking structure 6 can include a first docking structure and a second docking structure, the first docking structure is used to dock with the circuit terminal on the battery 30, and the second docking structure is used to dock with the liquid path port on the battery 30. Wherein, the relative positions of the first docking structure and the second docking structure are not limited, for example, they can be spaced apart in the horizontal direction, for example, left and right or front and back, so that the first docking structure and the second docking structure do not interfere with each other when docking respectively. Of course, the above-mentioned first docking structure and second docking structure are only used to illustrate part of the docking structure 6, and do not represent a limitation thereto.

[0342] In some embodiments, as shown in Figure 13 and Figure 14 The main body part 1 has a beam avoiding groove 13 with an opening penetrating along the length direction (such as the first direction X) of the beam 20, and the docking structure 6 is located in the beam avoiding groove 13. In the embodiments of the present application, the length direction of the vehicle body, the length direction of the vehicle 1000, and the length direction of the beam 20 are consistent, the width direction of the vehicle body, the width direction of the vehicle 1000, and the width direction of the beam 20 are consistent, and the height direction of the vehicle body, the height direction of the vehicle 1000, and the height direction of the beam 20 are consistent.

[0343] Therefore, by providing the beam avoiding groove 13 on the main body part 1, when the main body part 1 is connected with the vehicle body, at least part of the beam 20 can extend into the beam avoiding groove 13, the extension direction of the beam 20 is the same as the penetrating direction of the opening, avoiding the interference between the battery mounting rack 10 and the beam 20, improving the compactness of the cooperation between the battery mounting rack 10 and the beam 20, which is beneficial to use the space near the beam 20 to set the battery 30, thereby facilitating to increase the size and size energy density of the battery 30. Moreover, by setting the docking structure 6 in the beam avoiding groove 13, the space in the beam avoiding groove 13 can be fully utilized to improve the space utilization, and it is convenient to reduce the space occupation of the docking structure 6 to other positions of the battery mounting rack 10, thereby improving the size and size energy density of the battery 30.

[0344] Moreover, the docking structure 6 can obtain the protection of the inner wall of the beam avoiding groove 13, so as to reduce the probability of damage of the docking structure 6 caused by collision, improve the problem of corrosion and failure of the docking structure 6 caused by mud and the like, improve the reliability and stability of the docking, and reduce the risk of electrical failure of the docking structure 6 caused by mud and water splashing erosion. Moreover, the docking structure 6 does not need to occupy the space outside the beam 20, and will not interfere with the connection between the battery mounting rack 10 and the beam 20 or the battery 30, and at the same time, it is beneficial to shorten the distance between the vehicle body and the docking structure 6, so as to reduce the connection difficulty between the vehicle body and the docking structure 6.

[0345] In some embodiments, as shown inFigure 13 and Figure 14 As shown in FIG. 1 and FIG. 2, the main body 1 includes a plurality of first main body walls 11 arranged at intervals along the length direction (e.g., the first direction X) of the vehicle beam 20, and an avoidance opening 15 is formed between any two adjacent first main body walls 11. The docking interface (e.g., the interface of the circuit and / or the interface of the liquid path) of the docking structure 6 is higher than the first main body wall 11 and is arranged corresponding to the avoidance opening 15. Here, the height direction of the vehicle body is defined as the up-down direction, which is consistent with the height direction of the vehicle 1000 and is the up-down direction in the direction of gravity.

[0346] Therefore, since the docking interface of the docking structure 6 is higher than the first main body wall 11, the ground clearance of the docking interface of the docking structure 6 is larger, better protection can be obtained, and the height of the docking interface of the docking structure 6 is beneficial to save space, increase the height size of the battery 30, improve the compactness of the cooperation between the battery mounting rack 10 and the battery 30, fully utilize the space, and increase the size and size energy density of the battery 30. Moreover, by arranging the avoidance opening 15, when the battery 30 is mounted on the battery mounting rack 10, part of the battery 30 can extend upward into the avoidance opening 15 and dock with the docking interface of the docking structure 6, thereby meeting the docking requirements.

[0347] In some embodiments, as shown in FIG. 1 and FIG. 2, the docking structure 6 includes a bearing rack 61 and a docking device 62. The bearing rack 61 includes a bearing portion 611 and a leg portion 612. The docking device 62 is arranged on the bearing portion 611. The leg portion 612 extends from both ends of the bearing portion 611 in the length direction (e.g., the first direction X) of the vehicle beam 20 towards the first main body wall 11 and is connected to the first main body wall 11. Figure 13 and Figure 14 In the above technical solution, by arranging the docking device 62 on the bearing portion 611 and arranging the leg portion 612 to extend from both ends of the bearing portion 611 in the length direction (e.g., the first direction X) of the vehicle beam 20 towards the first main body wall 11 and connected to the first main body wall 11, the bearing portion 611 can be spaced apart from the first main body wall 11, so that the bearing rack 61 can be constructed in a shape that can avoid the battery 30 upwardly, and the height of the docking device 62 can be increased to save space and increase the height size of the battery 30.

[0348] In the above technical solution, by arranging the docking device 62 on the bearing portion 611 and arranging the leg portion 612 to extend from both ends of the bearing portion 611 in the length direction (e.g., the first direction X) of the vehicle beam 20 towards the first main body wall 11 and connected to the first main body wall 11, the bearing portion 611 can be spaced apart from the first main body wall 11, so that the bearing rack 61 can be constructed in a shape that can avoid the battery 30 upwardly, and the height of the docking device 62 can be increased to save space and increase the height size of the battery 30.

[0349] When the length direction (e.g., the first direction X) of the vehicle beam 20 is the length direction of the vehicle 1000, the two leg portions 612 arranged on both sides of the bearing portion 611 in the length direction (e.g., the first direction X) of the vehicle beam 20 can only occupy the space of the battery 30 in the length direction of the vehicle 1000, which is relatively sufficient, and can reduce the occupation of the space of the battery 30 in the width direction of the vehicle 1000, which is conducive to improving the size and energy density of the battery 30 in the width direction of the vehicle 1000.

[0350] In some embodiments, as shown in Figure 13 and Figure 14 The bearing portion 611 has a third weight-reducing structure 613, and / or the connection between the leg portion 612 and the bearing portion 611 is provided with a first reinforcing structure 614.

[0351] Thus, by arranging the third weight-reducing structure 613 on the bearing portion 611, the weight of the bearing portion 611 is reduced, and the weight of the docking structure 6 is reduced, so as to realize the lightweight design of the docking structure 6. The third weight-reducing structure 613 can include but is not limited to a weight-reducing hole, or a weight-reducing groove, or a thinning treatment, etc.

[0352] Thus, by arranging the first reinforcing structure 614 at the connection between the bearing portion 611 and the leg portion 612, the structural strength of the connection between the bearing portion 611 and the leg portion 612 is enhanced, and the possibility of fracture at the connection between the leg portion 612 and the bearing portion 611 is reduced, so as to facilitate the reduction of the thickness of the bearing portion 611 and the leg portion 612, and to realize the lightweight design of the docking structure 6. The first reinforcing structure 614 can include but is not limited to a reinforcing rib, a strip-shaped reinforcing protrusion, or a local thickening treatment of the extension portion 2, etc., and when the first reinforcing structure 614 is arranged as a reinforcing rib, the structural form of the reinforcing rib is not limited, which can be linear, or curved, or cross-shaped, etc.

[0353] In some embodiments, as shown in Figure 13 and Figure 14 The bearing frame 61 is an integral molding member and is assembled and connected with the first main body wall 11. Thus, by arranging the bearing frame 61 as an integral molding member, the difficulty of arranging the bearing frame 61 is reduced, and the overall structural strength of the bearing frame 61 is facilitated to be ensured, and the bearing frame 61 is assembled and connected with the first main body wall 11, so as to reduce the assembly difficulty of the bearing frame 61 and the first main body wall 11, and to improve the production efficiency of the battery mounting frame 10.

[0354] In addition, the bearing frame 61 can also not be an integral molding member, for example, the bearing portion 611 and the leg portion 612 can also be assembled and connected. The "assembly connection" includes but is not limited to welding connection, or bolt connection, or clamping connection, or plug-in connection, etc.

[0355] In some embodiments, as shown in Figure 13 and Figure 14 The battery mounting space 4 and the avoidance opening 15 can be arranged in multiple sets along the length direction (e.g., the first direction X) of the vehicle beam 20, and the avoidance opening 15 corresponds to the battery mounting space 4 along the width direction (e.g., the second direction Y) of the vehicle beam 20. Each avoidance opening 15 is provided with a corresponding docking structure 6. Thus, when the size of the battery 30 is large, the part of the battery 30 corresponding to the battery mounting space 4 can extend into the battery mounting space 4, and the part corresponding to the avoidance opening 15 can extend into the avoidance opening 15 to dock with the docking structure 6. Moreover, by arranging multiple avoidance openings 15, when multiple batteries 30 are mounted on the battery mounting rack 10, the communication requirements of the circuit and / or liquid circuit of the vehicle body can be met by the multiple docking structures 6, i.e., each battery 30 can meet the communication requirements of the circuit and / or liquid circuit of the vehicle body by docking with the corresponding docking structure 6, so that the vehicle 1000 can realize individual communication with each battery 30 through the corresponding docking structure 6, which is beneficial for individual power supply and control of each battery 30.

[0356] In some embodiments, as shown in Figure 4 When the main body 1 is provided with multiple battery mounting spaces 4 arranged in multiple sets along the length direction (e.g., the first direction X) of the vehicle beam 20, the docking structure 6 can also be arranged in multiple sets along the length direction (e.g., the first direction X) of the vehicle beam 20, and the multiple docking structures 6 are arranged opposite to the multiple battery mounting spaces 4 along the second direction Y, which intersects (e.g., at an acute angle, an obtuse angle, or a right angle) the length direction (e.g., the first direction X) of the vehicle beam 20.

[0357] Thus, when the size of the battery 30 is large, the part of the battery 30 corresponding to the battery mounting space 4 can extend into the battery mounting space 4, and the part corresponding to the docking structure 6 can dock with the docking structure 6. The distribution direction of the docking structure 6 does not occupy the space of the battery mounting space 4 in the length direction (e.g., the first direction X) of the vehicle beam 20, i.e., the docking structure 6 does not occupy the space in the arrangement direction of the multiple battery mounting spaces 4 while docking with the battery 30, which is beneficial for increasing the number or size of the battery mounting spaces 4 arranged along the length direction (e.g., the first direction X) of the vehicle beam 20, improving the space utilization, and enabling the battery mounting rack 10 to mount more batteries 30.

[0358] It should be noted that the specific structure of the vehicle beam 20 according to the embodiments of the present application is not limited, for example, the vehicle beam 20 can include two longitudinal beams 201 extending along the length direction of the vehicle beam 20 and at least one cross beam 202 extending along the width direction of the vehicle, the two longitudinal beams 201 are arranged in a spaced manner along the width direction of the vehicle, and the cross beam 202 is connected between the two longitudinal beams 201. Since the vehicle beam 20 includes two longitudinal beams 201 extending along the length direction (such as the first direction X) of the vehicle beam 20 and arranged in a spaced manner along the second direction Y, the second direction Y can be arranged to be orthogonal to the length direction (such as the first direction X) of the vehicle beam 20.

[0359] In some embodiments, when the vehicle beam 20 includes two longitudinal beams 201 extending along the length direction of the vehicle beam 20 and arranged in a spaced manner along the width direction of the vehicle beam 20, the docking structure 6 can be arranged between the two longitudinal beams 201, and the two longitudinal beams 201 can protect the docking structure 6 to some extent, thereby reducing damage to the docking structure 6, prolonging the service life of the docking structure 6, and enabling the docking structure 6 to make full use of the space between the two longitudinal beams 201 to improve space utilization and facilitate reduction of the volume of the battery mounting rack 10, thereby improving the capacity of the battery 30. Moreover, the part of the docking structure 6 located between the two longitudinal beams 201 can be protected by the two longitudinal beams 201 to reduce the probability of damage to the docking structure 6 by knocking, improve the problem of corrosion and failure of the docking structure 6 by mud and the like, improve the reliability and stability of the docking, and reduce the risk of electrical failure of the docking structure 6 caused by mud and water splashing erosion. Moreover, the docking structure 6 does not need to occupy space outside the vehicle beam 20 and does not interfere with the cooperation of the battery mounting rack 10 with the vehicle beam 20 and the battery 30.

[0360] In some embodiments, as shown in Figure 13 and Figure 14 , the docking interface of the docking structure 6 is higher than the bottom surface of the longitudinal beam 201 and is arranged downward. Thus, since the docking interface of the docking structure 6 is higher than the bottom surface of the longitudinal beam 201, the ground clearance of the docking interface of the docking structure 6 is larger, better protection can be obtained, and the height of the docking interface of the docking structure 6 is arranged to facilitate saving of space to increase the height dimension of the battery 30 so that at least part of the battery 30 can extend into the space between the two longitudinal beams 201, improve the compactness of the cooperation of the battery mounting rack 10 with the battery 30, make full use of the space, and increase the size and size energy density of the battery. Moreover, by arranging the docking interface to be arranged downward, the battery 30 can be mounted from bottom to top while achieving the docking of the battery 30 with the docking structure 6, thereby improving the battery replacement efficiency.

[0361] In this way, the docking direction of the battery 30 when it is connected to the vehicle 1000 is arranged along the height direction of the vehicle 1000. Since the battery 30 is also arranged along the height direction of the vehicle 1000 when it is mounted on the vehicle 1000, the docking direction of the battery 30 can coincide with the battery swapping direction. Therefore, there is no need to set up docking space in the length or width direction of the vehicle 1000, which improves space utilization. Furthermore, the mounting and docking of the battery 30 can be carried out in the same direction, thereby improving the battery swapping efficiency.

[0362] In some embodiments, such as Figure 13 and Figure 14 As shown, the docking interface of the docking structure 6 is higher than the bottom surface of the longitudinal beam 201 and is positioned downwards. Therefore, because the docking interface of the docking structure 6 is higher than the bottom surface of the longitudinal beam 201, the docking interface of the docking structure 6 has a greater height from the ground, providing better protection. Furthermore, the height of the docking interface of the docking structure 6 helps save space, increasing the height of the battery 30 so that at least a portion of the battery 30 can extend between the two longitudinal beams 201, improving the tightness of the fit between the battery mounting bracket 10 and the battery 30, making full use of space, and increasing the size and energy density of the battery. Moreover, by setting the docking interface downwards, the battery 30 can be docked with the docking structure 6 while being mounted from bottom to top, thereby improving battery swapping efficiency.

[0363] In this way, the docking direction of the battery 30 when it is connected to the vehicle 1000 is arranged along the height direction of the vehicle 1000. Since the battery 30 is also arranged along the height direction of the vehicle 1000 when it is mounted on the vehicle 1000, the docking direction of the battery 30 can coincide with the battery swapping direction. Therefore, there is no need to set up docking space in the length or width direction of the vehicle 1000, which improves space utilization. Furthermore, the mounting and docking of the battery 30 can be carried out in the same direction, thereby improving the battery swapping efficiency.

[0364] In some embodiments, please refer to Figure 15 The battery 30 includes two battery side portions 30e and a battery central portion 30f. In the width direction (e.g., the second direction Y) of the vehicle beam 20, the two battery side portions 30e are located on both sides of the battery central portion 30f. The top surface of the battery central portion 30f is lower than the top surface of the battery side portions 30e, so that a clearance groove 30g is formed between the two battery side portions 30e and the battery central portion 30f, which extends along the length direction (e.g., the first direction X) of the vehicle beam 20 and has an open top. At this time, a docking portion 30h for docking with the docking structure 6 can be provided on the top of the battery central portion 30f.

[0365] Therefore, when the battery 30 moves from bottom to top along the height direction of the vehicle 1000, the butt joint of the butt joint structure 6 between the butt joint part 30h of the battery 30 and the two longitudinal beams 201 can be easily realized, thereby facilitating to reduce the difficulty of battery replacement operation, improve the battery replacement efficiency, and save the space required for battery replacement operation. Further, when the butt joint interface of the butt joint structure 6 is arranged downward, the battery 30 can be mounted on the mounting structure 3 from bottom to top while realizing the butt joint of the battery 30 and the butt joint structure 6 synchronously. In this way, the butt joint space of the battery 30 and the vehicle 1000 is arranged along the height direction of the vehicle 1000, and since the battery replacement movement space of the battery 30 is also arranged along the height direction of the vehicle 1000 when the battery 30 is mounted on the vehicle 1000, the butt joint direction of the battery 30 can coincide with the battery replacement movement direction, thereby not needing to additionally arrange the butt joint space in the length or width direction of the vehicle 1000 to improve the space utilization rate, and the battery replacement of the battery 30 and the butt joint of the battery 30 can be performed synchronously, thereby improving the battery replacement efficiency.

[0366] In recent years, commercial electric vehicles in logistics, ports, mines and other application scenarios, battery replacement mode has become an important way to supplement energy for pure electric commercial vehicles, and the construction pace of battery replacement stations has also begun to accelerate. In order to make the battery replacement have universal interchangeability, so that the battery replacement station, charging equipment and other battery replacement facilities can be fully utilized, and the resource waste is reduced.

[0367] The application proposes some embodiments about chassis type battery replacement to improve the compatibility and interchangeability of battery replacement. However, the following embodiments are not limited to pure electric vehicles, and other forms of battery replacement vehicles can be used for reference.

[0368] In some embodiments, the working voltage range of the battery replacement battery system is 400V-750V.

[0369] In some embodiments, the flatness of the battery replacement battery system battery replacement contact surface is ≤4mm. Specifically, the contact interface of the battery replacement battery system and the battery mounting rack should be a plane without convex structure, and the flatness should be less than 4mm.

[0370] In some embodiments, the dimensional tolerance of the battery replacement battery system is within ±10mm.

[0371] In some embodiments, the weight M1 of the vehicle and the electric quantity Q of the battery in the battery replacement battery system satisfy: 0kg

[0372] In some embodiments, such as Figures 16-17 As shown, the battery swapping system should be replaced on the vehicle within the corresponding envelope space. The battery dimensions in the battery swapping system are as follows: Figures 18-19 Logo.

[0373] In some embodiments, reference Figures 16-19 The front and rear ends of the battery swapping system are reserved with a safety gap L0 between them and the vehicle, and L0 ≥ 50 mm.

[0374] In some embodiments, reference Figures 16-19 The dimensions L of the battery swapping system along the length of the vehicle must satisfy: 700mm≤L≤900mm; or 1500mm≤L≤1700mm; or 2300mm≤L≤2500mm; or 3100mm≤L≤3300mm.

[0375] In some embodiments, reference Figures 16-19 The dimension W of the battery swapping system along the vehicle width direction must satisfy: 2300mm≤W≤2550mm.

[0376] In some embodiments, reference Figures 16-19 The total height H of the battery swapping system must satisfy: H≤680mm.

[0377] In some embodiments, reference Figures 16-19 The length L1 of the upper boss (such as the upper part of the battery 30a) of the battery swapping system shall satisfy: 600mm≤L1≤700mm.

[0378] In some embodiments, reference Figures 16-19 The width W1 of the upper two side protrusions of the battery swapping system (such as the upper part 30a of the battery side 30e) must satisfy: W1≤805mm.

[0379] In some embodiments, reference Figures 16-19 The width W2 of the upper middle boss of the battery swapping system (such as the upper part 30a of the battery center 30f) must satisfy: W2≤640mm.

[0380] In some embodiments, reference Figures 16-19 The height dimension H1 of the upper two side bosses of the battery swapping system (such as the upper part 30a of the battery side 30e) must satisfy: H1≤300mm.

[0381] In some embodiments, reference Figure 20 The height dimension H2 of the upper middle boss of the battery swapping system (such as the upper part 30a of the battery center 30f) must satisfy: H2≤150mm.

[0382] The application scenarios of heavy-duty electric vehicles currently mainly include trunk line logistics, medium and short distance operation (such as city waste transportation), and closed operation scenarios (such as ports). The demand for electricity can be roughly divided into three categories: 400-600kWh, 300-400kWh, and 150-200kWh. According to the above series of electricity, the standard battery package scheme can be flexibly matched to meet the needs of different scenarios. For example, the standard battery system has an electricity capacity of about 150-200kWh, which can be matched with three standard battery systems (three-pack), two standard battery systems (two-pack), or a single standard battery system (single-pack) to meet the electricity demand.

[0383] The main models of heavy-duty electric vehicles currently include 6*4 tractor, 4*2 tractor, 8*4 dump truck, 6*4 dump truck, 4*2 cargo truck, and 6*4 cargo truck. Among them, the 6*4 tractor and 8*4 dump truck have relatively short wheelbase, and the other models are compatible. The wheelbase of the 6*4 tractor is 3300mm, which is the ideal wheelbase, but it is currently not possible to arrange a large amount of electricity. For the rear battery replacement model, the wheelbase is currently extended to 3800mm, which also cannot arrange the target electricity capacity. The wheelbase of the current push client can be extended to 4200mm, and the battery space can be arranged based on this wheelbase. The wheelbase of the 8*4 dump truck is relatively long, which ensures the transportation capacity, and the wheelbase can be increased. This space can arrange the target electricity capacity. The wheelbase of the traditional fuel vehicle in the city 8*4 dump truck is 2500-2600mm, which also cannot arrange the target electricity capacity. For the rear battery replacement model, the wheelbase is extended to 3200-3300mm, and the battery space can be arranged based on the extended wheelbase.

[0384] The factors limiting the space of the battery front end include leaf springs and their brackets. Considering the heavy load, the industry currently generally has a wheelbase of 1600-1800mm (single side 900mm). The factors limiting the space of the battery rear end include mudguards, which are about 700mm away from the center of the wheel. The front and rear ends of the battery each have a safety gap of 50mm. Therefore, the envelope size of the battery replacement system for the 6*4 tractor is about 4200-900-700-100=2500mm (three-pack), and the envelope size of the battery replacement system for the 8*4 dump truck is about 3300-900-700-100=1600mm (two-pack). Based on the envelope space of the above two battery replacement systems, considering the gap between the battery replacement systems and the battery replacement systems, the length envelope size of each battery replacement system is about 700-820mm.

[0385] The width envelope size of the battery replacement system can be designed to not exceed the required vehicle width, for example, the vehicle width of a heavy-duty electric vehicle is 2550mm.

[0386] The height envelope size of the battery swap system is designed to consider that the upper end of the battery swap system maintains a 20mm gap with the upper surface of the vehicle beam, and the bottom surface of the battery swap system maintains a 300mm or 400mm or more ground clearance. The height of the upper surface of the vehicle beam from the ground is generally 1000-1100mm. Therefore, the height envelope size of the battery swap system is approximately 580-780mm.

[0387] In order to improve the compatibility and interchangeability of battery swapping, the application also proposes some embodiments of the battery mounting rack 10.

[0388] In some embodiments, with reference to Figure 20 The length of the battery mounting space 4 in the length direction (e.g., the first direction X) of the vehicle is Y1, and satisfies: 620mm≤Y1≤720mm.

[0389] In some embodiments, with reference to Figure 20 The width of the battery mounting space 4 in the width direction (e.g., the second direction Y) of the vehicle is N1, and satisfies: 690mm≤N1≤815mm.

[0390] In some embodiments, with reference to Figure 21 The minimum width between the two second body walls 12 (or the width of the avoidance opening 15) in the width direction (e.g., the second direction Y) of the vehicle is N2, and satisfies: 660mm≤N2≤680mm.

[0391] In some embodiments, with reference to ​ The total width of the battery mounting rack 10 in the width direction (e.g., the second direction Y) of the vehicle is P, and the total length of the battery mounting rack 10 in the length direction (e.g., the first direction X) of the vehicle is R, and satisfies: 2300mm≤P≤2550mm, 700mm≤R≤900mm (e.g., only one battery mounting space 4), or 1500mm≤R≤1700mm (e.g., two battery mounting spaces 4), or 2300mm≤R≤2500mm (e.g., three battery mounting spaces 4), or 3100mm≤R≤3300mm (e.g., four battery mounting spaces 4).

[0392] The above embodiments are only used to illustrate the technical solutions of the present application, rather than limit them; although the present application has been described in detail with reference to the foregoing embodiments, it should be understood by those skilled in the art that the technical solutions recorded in the foregoing embodiments can still be modified, or some or all of the technical features can be replaced equivalently; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should be covered in the scope of the claims and the specification of the present application. In particular, as long as there is no structural conflict, each technical feature mentioned in each embodiment can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
