[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application is based on the Chinese patent application with application number 202310799492.4 and application date June 30, 2023, and claims the priority of the above-mentioned Chinese patent application. The entire content of the above-mentioned Chinese patent application is hereby introduced into this application as a reference. Technical Field

[0003] The present application relates to the field of batteries, and in particular to a battery mounting rack, a frame assembly and a vehicle. Background Art

[0004] Energy conservation and emission reduction are key to the sustainable development of the automotive industry. Electric vehicles, due to their energy-saving and environmentally friendly advantages, have become a crucial component of this sustainable development. Battery technology is a crucial factor in the development of electric vehicles. However, when a vehicle's battery pack is replaced at a battery swap station, the battery pack is often not fully discharged, resulting in energy waste.

[0005] Summary of the Invention

[0006] In view of the above problems, the present application provides a battery mounting rack, a frame assembly and a vehicle, wherein the battery mounting rack can mount multiple batteries and the batteries to be replaced can be selected according to actual conditions, thereby improving the problem of energy waste.

[0007] In the first aspect, the present application provides a battery mounting rack, which includes a first rack, the first rack including a plurality of extensions arranged at intervals along a first direction and a plurality of battery mounting spaces arranged in sequence along the first direction, the battery mounting space being defined between two adjacent extensions along the first direction, and a battery mounting structure for mounting a battery in the battery mounting space being provided on the battery mounting rack.

[0008] In the technical solution of the embodiment of the present application, when such a battery mounting rack is used to install batteries on a vehicle, since the battery mounting rack includes multiple battery mounting spaces and is provided with a battery mounting structure, each battery mounting space can be used to mount a battery. Thus, a battery can be mounted separately in each battery mounting space. In this way, the battery mounting rack can accommodate multiple batteries. When replacing batteries, only exhausted batteries can be replaced while remaining batteries are retained, thereby improving battery energy utilization and alleviating energy waste. Furthermore, when the battery mounting rack is used in a vehicle, the first direction can be set to the longitudinal direction of the vehicle, so that the battery mounting rack can accommodate multiple batteries along the longitudinal direction of the vehicle. This helps increase the number of batteries that can be arranged on the vehicle and helps increase the size of the battery mounting space in the length and width directions of the vehicle, thereby increasing the battery's dimensional energy density. Furthermore, the battery mounting space is defined between two adjacent extensions along the first direction. The extensions can be used to protect the batteries, thereby alleviating problems such as collision and heat transfer between batteries in two adjacent battery mounting spaces along the first direction.

[0009] In some embodiments, at least two battery mounting spaces on the first rack have the same length in the first direction.

[0010] In the above technical solution, since the lengths of at least two battery mounting spaces on the first rack are consistent in the first direction, it is convenient to install batteries of the same specification in the at least two battery mounting spaces with the same lengths in the first direction, so that the batteries can be installed in any one of the battery mounting spaces, thereby improving the installation efficiency and flexibility.

[0011] In some embodiments, lengths of at least two battery mounting spaces on the first rack are inconsistent in the first direction.

[0012] In the above technical solution, since the lengths of at least two battery mounting spaces on the first rack are inconsistent in the first direction, when installing batteries of different specifications in the at least two battery mounting spaces with inconsistent lengths in the first direction, batteries of different specifications can be installed in battery mounting spaces of corresponding sizes respectively, so that the setting of the battery mounting space can match the specifications of the corresponding batteries, thereby reducing the waste of installation space and enabling the battery mounting rack to install at least two batteries of different specifications.

[0013] In some embodiments, the battery mounting rack includes two first racks spaced apart along a second direction, each first rack includes a plurality of battery mounting spaces sequentially arranged along a first direction, and the second direction intersects the first direction.

[0014] In the above technical solution, the battery mounting rack includes two first racks, and each first rack includes a plurality of battery mounting spaces arranged in sequence along the first direction, so that each first rack has the function of mounting multiple batteries in the first direction, and the two first racks are arranged at intervals along the second direction, which can make full use of the space in the second direction to increase the number of batteries that can be mounted on the battery mounting rack, which is beneficial to improving the vehicle's range of a single battery replacement.

[0015] In some embodiments, the extension portions in the two first frames are arranged in a one-to-one correspondence along the second direction, and the length extension directions of the two corresponding extension portions are the same, and their orthographic projections along the length extension direction coincide with each other.

[0016] In the above technical solution, through the above arrangement, the corresponding battery mounting spaces defined along the second direction on the two first racks are of the same size and correspondingly positioned. Therefore, when the battery mounting rack is used to install a large-sized, relatively regularly shaped battery, the two side portions of the battery can respectively cooperate with the two corresponding battery mounting spaces provided in the second direction. In this way, the two corresponding battery mounting spaces provided in the second direction can be used to jointly install a large-sized battery, which is beneficial for improving the energy density of the installed battery. Furthermore, when the extension portion has a battery mounting structure, the two extension portions correspondingly positioned along the second direction can respectively support the two side portions of the large-sized battery, thereby improving the force balance and mounting stability of the battery.

[0017] In some embodiments, the first direction is perpendicular to the second direction, the length extension direction of the extension portion is the second direction, and the battery mounting spaces on the two first racks are symmetrically arranged.

[0018] In this technical solution, the two ends of a symmetrically shaped, large battery can be mounted in two symmetrically arranged battery mounting spaces, meeting the mounting requirements of large batteries. Furthermore, the batteries or battery sections mounted in the symmetrical battery mounting spaces are more evenly distributed, applying a more even force to the battery mounting frame, which helps improve the structural stability of the battery mounting frame.

[0019] In some embodiments, the battery mounting frame further includes a second frame connecting two first frames spaced apart along the second direction, the second frame including a beam avoidance groove having an opening extending through along the first direction.

[0020] In the above technical solution, a second frame is provided so that the two first frames A can be connected into an integral structure through the second frame. In this way, for example, when the second frame is fixed to the vehicle frame, the battery mounting frame can be fixed, so that each first frame A reaches the use position, thereby reducing the difficulty of assembling the battery mounting frame. At the same time, the vehicle beam avoidance groove of the second frame has an opening that passes through along the first direction X, so that a part of the vehicle beam can extend into the vehicle beam avoidance groove, so that the vehicle beam avoidance groove can avoid the vehicle beam, avoid interference between the battery mounting frame and the vehicle beam, and improve the compactness of the cooperation between the battery mounting frame and the vehicle beam, which is conducive to utilizing the space near the vehicle beam to set the battery, thereby facilitating the increase of the battery size and dimensional energy density.

[0021] In some embodiments, the second rack includes a first main body wall, which is multiple and spaced apart along the first direction to form a battery avoidance opening between two adjacent first main body walls, and the battery avoidance opening is arranged opposite to the battery mounting space along the second direction.

[0022] In the above technical solution, a battery avoidance port is provided so that when a larger battery is installed in the battery mounting space, the battery can be avoided through the battery avoidance port to avoid interference between the battery and the second rack, thereby facilitating the installation of a larger battery and improving the energy density of the installed battery.

[0023] In some embodiments, the second frame also includes a second main body wall, which extends along the first direction. There are two second main body walls and are connected on both sides of each first main body wall at intervals along the second direction, so that the vehicle beam avoidance groove is defined between the first main body wall and the two second main body walls. The first frame is arranged on the side of the second main body wall away from the first main body wall in the second direction, and each extension portion is connected to the second main body wall.

[0024] In the above technical solution, by setting the second main body wall, multiple first main body walls and second main body walls can be connected into an integral structure, thereby reducing the difficulty of setting up the second frame, and facilitating the definition of the extension direction of the vehicle beam avoidance groove so that it extends along the first direction, wherein the first frame is arranged on the side of the second main body wall away from the first main body wall in the second direction, and each extension part is connected to the side of the second main body wall away from the first main body wall in the second direction to avoid interference between the extension part and the vehicle beam, and facilitate the expansion of the battery mounting space in the second direction, thereby facilitating the improvement of the battery size and dimensional energy density.

[0025] In some embodiments, the height of the extension portion decreases in a direction away from the second main body wall.

[0026] In the above technical solution, the height of the extension portion is set to decrease in the direction away from the second main body wall, so that the height of the area of ​​the extension portion away from the second main body wall is smaller. That is, the height of the end portion of the extension portion connected to the second main body wall is relatively large, while the height of the end portion of the extension portion away from the second main body wall is relatively small, thereby enhancing the connection strength between the extension portion and the second main body wall, improving the reliability of the extension portion for mounting the battery, and reducing the weight of the extension portion, thereby reducing the load on the vehicle.

[0027] In some embodiments, the lower edge of the extension portion extends along a horizontal line, the battery mounting structure is located at the lower edge of the extension portion, and the upper edge of the extension portion tends to decrease in a direction away from the second main body wall.

[0028] In the above technical solution, the height of the battery mounting structure is made lower, which is convenient for reducing the difficulty of mounting the battery, and is conducive to the battery mounting structures being located at the same horizontal height, thereby facilitating the battery mounting operation.

[0029] In some embodiments, a vehicle beam connecting structure is provided on at least one of the first frame and the second frame.

[0030] In the above technical solution, the vehicle beam connecting structure can be provided on the first frame, or the vehicle beam connecting structure can be provided on the second frame, or the vehicle beam connecting structure can be provided on both the first frame and the second frame. In this way, since the second frame cooperates with the vehicle beam through the vehicle beam avoidance groove, the second frame and the first frame can both have a portion close to the vehicle beam. In this way, by providing the vehicle beam connecting structure to be connected to the vehicle beam, it is possible to facilitate the installation of the battery mounting frame to the vehicle frame.

[0031] In some embodiments, at least one of a heat-insulating structure, a heat-dissipating structure, and a buffer structure is provided on a side of the extension portion facing the battery mounting space.

[0032] In the above technical solution, by providing a heat-insulating structural member, the heat transfer effect between two adjacent batteries can be improved. By providing a heat dissipation structural member, the heat dissipation effect of the battery can be played, thereby improving the overheating of the battery. By providing a buffering structural member, the buffering effect of the battery can be played, thereby improving the rigid contact between the battery and the buffer part, thereby playing a role in protecting the battery and helping to extend the service life of the battery.

[0033] In some embodiments, the battery mounting structure is disposed on the extension portion.

[0034] In the above technical solution, by setting the battery mounting structure on the extension part, the battery mounting structure only occupies the space in the first direction X, thereby avoiding the battery mounting structure from occupying space in other directions, which is beneficial to increasing the size of the battery in other directions.

[0035] In some embodiments, a battery mounting structure is arranged on a side of the extension portion facing the battery mounting space.

[0036] In the above technical solution, by arranging the battery mounting structure on the side of the extension portion facing the battery mounting space, the battery mounting structure corresponds to the battery mounting space that it faces, and is used to mount the battery in the battery mounting space that the battery mounting structure faces. This makes it possible to clearly identify the corresponding relationship between the battery mounting structure and the battery mounting space. When a battery is inserted into a battery mounting space, it can be connected to the battery mounting structure facing the battery mounting space, thereby conveniently achieving battery mounting. Moreover, when there are multiple battery mounting spaces, the battery mounting structures corresponding to different battery mounting spaces will not interfere with each other, so that the battery mounting structure corresponding to each battery mounting space can have sufficient space for flexible arrangement, so that the battery mounting structure can more easily and reliably mount the battery.

[0037] In some embodiments, at least one extension portion located in the middle of the multiple extension portions is a common extension portion, and the common extension portion has battery mounting spaces on both sides in the first direction, and battery mounting structures are arranged on both sides of the battery mounting spaces facing both sides of the common extension portion.

[0038] In the above technical solution, when the number of battery mounting spaces arranged at intervals along the first direction is fixed, the number of extensions arranged at intervals along the first direction can be reduced, thereby facilitating cost reduction and vehicle load reduction.

[0039] In some embodiments, the battery mounting structures on both sides of the common extension portion in the first direction are misaligned in their orthographic projections on a projection plane perpendicular to the first direction.

[0040] In the above technical solution, by setting the battery mounting structures on both sides of the common extension part to be misaligned in the projection on the projection plane perpendicular to the first direction, the force distribution of the common extension part is more reasonable. When the batteries in the battery mounting spaces on both sides of the common extension part are respectively connected to the battery mounting structures on both sides of the common extension part, stress concentration can be reduced to cause deformation, fracture and other problems in the common extension part, thereby improving the service life of the common extension part and thus improving the mounting reliability of the battery.

[0041] In some embodiments, the extension portion includes a mounting edge protruding toward the battery mounting space, and the battery mounting structure is located on the mounting edge.

[0042] In the above technical solution, by setting a mounting edge, it is helpful to reduce the difficulty of setting up the mounting structure, and it is easy to realize that the mounting structure is located on the side of the extension part facing the battery mounting space. Moreover, the mounting edge can play a certain direct or indirect supporting role on the battery to enhance the mounting stability of the battery.

[0043] In some embodiments, battery mounting structures are provided on the extension portions on both sides of the battery mounting space in the first direction.

[0044] In the above technical solution, the extension parts on both sides of the battery mounting space in the first direction can both play the role of supporting the batteries in the battery mounting space. The battery mounting structures on both sides can disperse the force to reduce stress concentration and cause deformation, fracture and other problems in the extension parts, thereby increasing the service life of the extension parts and improving the battery mounting reliability.

[0045] In some embodiments, the battery mounting structures on both sides of the battery mounting space in the first direction are misaligned in their orthographic projections on a projection plane perpendicular to the first direction.

[0046] In the above technical solution, by arranging the battery mounting structures on both sides of the battery mounting space so that their orthographic projections on a projection plane perpendicular to the first direction are offset, this further facilitates the distribution of force on the battery mounting structures on both sides, further alleviating stress concentration that can cause deformation and fracture of the extension. Furthermore, when the orthographic projections of the battery mounting structures on both sides of the common extension in the first direction are offset on a projection plane perpendicular to the first direction, and the orthographic projections of the battery mounting structures on both sides of the battery mounting space in the first direction are offset on a projection plane perpendicular to the first direction, multiple extensions can be constructed with the same structure, thereby simplifying the structure, facilitating processing, reducing costs, and improving assembly efficiency.

[0047] In some embodiments, a plurality of battery mounting structures are provided on a side of the extension portion facing the battery mounting space, and at least two battery mounting structures are spaced apart along the length direction of the extension portion.

[0048] In the above technical solution, it is beneficial to fully utilize the space in the length direction of the extension part and arrange more battery mounting structures, thereby enhancing the mounting stability of the battery, or increasing the number of batteries mounted in the battery mounting space.

[0049] In some embodiments, the extension portion is plate-shaped, with the thickness direction being the first direction, the length direction being the second direction, and the width direction being the height direction.

[0050] In the above technical solution, by configuring the extension portion to be plate-shaped and defining the first and second directions as described above, the battery mounting space can be located on one or both sides of the thickness direction of the extension portion. This allows the length structural characteristics of the extension portion to be fully utilized to define the battery mounting space, resulting in a smaller space occupied by the extension portion and a larger defined battery mounting space. Furthermore, the battery mounting rack defines multiple battery mounting spaces in the thickness direction of the extension portion, with the distance between two adjacent battery mounting spaces in the thickness direction of the extension portion being the thickness of the extension portion. This reduces the gap between two adjacent battery mounting spaces, allowing for more battery mounting spaces to be provided in the thickness direction of the extension portion, further improving space utilization.

[0051] In some embodiments, reinforcing ribs and / or weight-reducing structures are provided on the extension portion.

[0052] In the above technical solution, the reinforcement ribs are provided to enhance the structural strength of the extension, improve the deformation problem of the extension under stress, and improve the reliability of the extension for mounting batteries. The weight-reducing structure is provided to reduce the weight of the extension, thereby achieving a lightweight design of the extension.

[0053] In some embodiments, the first frame further includes a reinforcement portion connecting the at least two extension portions.

[0054] In the above technical solution, it is beneficial to enhance the overall structural strength of the battery mounting frame, reduce the deformation caused by the force on the extension part, and improve the mounting reliability of the battery.

[0055] In a second aspect, the present application provides a vehicle frame assembly, which includes a vehicle frame and a battery mounting bracket as described in any one of the above embodiments, wherein the battery mounting bracket is used to mount the battery to the vehicle frame, and the first direction is the length direction of the vehicle frame.

[0056] In the above technical solution, when using such a battery mounting rack to install the battery on the vehicle, since the battery mounting rack includes a plurality of battery mounting spaces arranged in sequence along the length direction of the frame, the battery mounting rack can make full use of the space in the length direction of the frame to install a larger number of batteries. Moreover, when replacing the battery, only the exhausted battery can be replaced, while the unused battery can be retained, thereby improving the energy utilization rate of the battery and improving the energy waste problem.

[0057] In some embodiments, the battery mounting bracket is installed at the bottom of the frame, the frame includes a beam, and a first bracket is provided on at least one side of the beam in the width direction, and at least a portion of the first bracket is higher than the bottom surface of the beam of the frame in the height direction of the frame.

[0058] In the above technical solution, the battery mounting space is not completely lower than the vehicle beam, but is at least partially higher than the bottom surface of the vehicle beam and is located on at least one side in the width direction of the vehicle beam, so that the bottom space of the frame can be fully utilized to arrange the extension part and the battery mounting space, so as to facilitate mounting larger batteries on the battery mounting frame, thereby increasing the vehicle's range per single battery replacement.

[0059] In some embodiments, the first frames are symmetrically provided on both sides of the vehicle beam in the width direction.

[0060] In the above technical solution, by arranging the first frames on both sides of the width direction of the vehicle beam, and the first frames on both sides of the width direction of the vehicle beam are symmetrically arranged, the structure of the battery mounting frame can be simplified, which is convenient for processing, and the bottom space of the vehicle can be fully utilized to mount more or larger batteries.

[0061] In a third aspect, the present application provides a vehicle comprising a battery and a frame assembly as described in any one of the above embodiments, wherein at least a portion of the battery is accommodated in a battery mounting space.

[0062] In the above technical solution, at least a portion of the battery is accommodated within the battery mounting space, allowing the battery to be mounted on the vehicle, thereby increasing the battery's ground clearance and the vehicle's ground clearance. This also facilitates full utilization of the battery mounting space, reducing the installation space occupied by the battery. Furthermore, this helps increase the number of batteries that can be mounted, allowing for the selection of swappable batteries as needed, thereby reducing energy waste.

[0063] In some embodiments, the battery is removably installed in any battery mounting space.

[0064] In the above technical solution, the battery can be installed in any one of the battery mounting spaces. In this way, the versatility of the battery mounting space can be increased, so as to reduce the difficulty of mounting the battery and improve the flexibility of the battery replacement installation location selection.

[0065] In some embodiments, the vehicle includes a plurality of batteries arranged along a first direction, and the plurality of batteries are installed in a plurality of battery mounting spaces in a one-to-one correspondence.

[0066] In the above technical solution, multiple batteries are installed one by one in multiple battery mounting spaces, so that multiple batteries arranged along the first direction can be mounted and installed through the first frame, that is, multi-pack mounting is achieved, thereby making full use of the space in the length direction of the vehicle to increase the number of batteries, so as to improve the vehicle's cruising range per single battery replacement.

[0067] In some embodiments, the battery includes an upper battery part and a lower battery part, the upper battery part is accommodated in the battery mounting space, and the battery is provided with a mounting structure between the upper battery part and the lower battery part, and the mounting structure is detachably connected to the battery mounting structure.

[0068] In the above technical solution, when the battery is mounted on the battery mounting rack, the upper part of the battery can extend into the battery mounting space, and the extension part can be used to protect the upper part of the battery to reduce the risk of damage to the battery, which is beneficial to extending the service life of the battery. At the same time, the height of the extension part can be less than the height of the battery, and the height of the extension part can be reduced, thereby reducing the weight and cost of the battery mounting rack. Moreover, the mounting structure is arranged at a position between the upper part and the lower part of the battery, so that it is possible for the battery mounting structure to be located at the lower edge of the extension part, which is beneficial to the battery replacement operation.

[0069] In some embodiments, in the first direction, the size of the upper portion of the battery is smaller than the size of the lower portion of the battery to form a step surface between the upper portion of the battery and the lower portion of the battery, the bottom of the battery mounting space is open, and the step surface stops at the bottom of the extension portion.

[0070] In the above technical solution, when the battery is actually installed, the bottom of the extension and the stop on the stepped surface can be used to indicate that the battery is properly installed when the upper portion of the battery is extended from the bottom to the top into the battery mounting space. This prevents the battery from extending too far into the battery mounting space and causing impact with the vehicle bottom, thereby protecting the battery. In addition, setting the size of the lower portion of the battery larger than that of the upper portion can further increase the battery size to a certain extent, thereby further improving the battery's size and energy density.

[0071] In some embodiments, the battery includes two battery side portions and a battery central portion. In the width direction of the frame, the two battery side portions are respectively located on both sides of the battery central portion, and the top surface of the battery central portion is lower than the top surface of the battery side portions, so as to form a clearance groove between the two battery side portions and the battery central portion, which passes through the length direction of the frame and has an open top for avoiding the vehicle beam. At least one of the battery side portions and the battery central portion is detachably connected to the battery mounting structure.

[0072] In the above technical solution, the battery structure is ingenious. By avoiding the vehicle beam to fully utilize the space on both sides of the width of the vehicle beam, the overall size of the battery can be increased to improve the battery's size energy density. At the same time, at least one of the battery side and the battery center is detachably connected to the battery mounting structure, which is conducive to improving the design flexibility of the battery.

[0073] The above description is only an overview of the technical solution of the present application. In order to more clearly understand the technical means of the present application, it can be implemented in accordance with the contents of the specification. In order to make the above and other purposes, features and advantages of the present application more obvious and easy to understand, the specific implementation methods of the present application are listed below.

[0100] Current market developments indicate that power batteries are becoming increasingly widely used. They are not only used in energy storage systems such as hydropower, thermal, wind, and solar power plants, but are also widely used in electric vehicles like electric bicycles, electric motorcycles, and electric cars, as well as in military equipment and aerospace. As power battery applications continue to expand, market demand is also growing.

[0101] Some vehicles in the related art typically use a tray to install the battery pack under the vehicle. This involves placing the battery pack on a tray, which is then mounted under the vehicle. When the battery needs to be replaced, the tray is removed, the entire battery pack inside is replaced, and the tray is then reinstalled under the vehicle. However, during the battery replacement process, the battery pack inside the tray is often not fully depleted, resulting in energy waste.

[0102] To this end, the present application proposes a battery mounting rack, wherein the battery mounting rack includes a first rack, the first rack includes a plurality of extensions arranged at intervals along a first direction and a plurality of battery mounting spaces arranged in sequence along the first direction, the battery mounting space is defined between two adjacent extensions along the first direction, and the battery mounting rack is provided with a battery mounting structure for mounting the battery in the battery mounting space.

[0103] When using such a battery mounting rack to install a battery on a vehicle, since the battery mounting rack includes multiple battery mounting spaces and a battery mounting structure is provided on the battery mounting rack, each battery mounting space can be used to mount a battery, so that a battery can be mounted separately in each battery mounting space. In this way, the battery mounting rack can have the function of installing multiple batteries. When replacing the battery, only the exhausted battery can be replaced, and the unused battery can be retained, thereby improving the energy utilization rate of the battery and improving the energy waste problem.

[0104] In addition, since the battery mounting space is limited between two adjacent extension parts, the extension parts can protect the batteries, improve the problem of batteries in two battery mounting spaces adjacent to each other along the first direction colliding with each other, and improve the heat transfer problem between the batteries in two battery mounting spaces adjacent to each other along the first direction, thereby improving the working reliability of the batteries.

[0105] The battery disclosed in the embodiments of the present application can be used in electrical devices that use the battery as a power source or various energy storage systems that use the battery as an energy storage element. The electrical device can be, but is not limited to, a mobile phone, a tablet, a laptop computer, an electric toy, an electric tool, a battery car, an electric car, a ship, a spacecraft, and the like. Among them, the electric toy can include fixed or mobile electric toys, such as game consoles, electric car toys, electric ship toys, and electric airplane toys, and the like, and the spacecraft can include airplanes, rockets, space shuttles, and spacecraft, and the like.

[0106] For the convenience of description, the following embodiments are described using a vehicle 1000 as an example of an embodiment of the present application.

[0107] Please refer to Figure 1, which is a schematic structural diagram of a vehicle 1000 provided in some embodiments of the present application. The vehicle 1000 can be a fuel vehicle, a gas vehicle or a new energy vehicle. The new energy vehicle can be a pure electric vehicle, a hybrid vehicle or an extended-range vehicle, etc. A battery 30 is provided inside the vehicle 1000, and the battery 30 can be provided at the bottom, head or tail of the vehicle 1000. The battery 30 can be used to power the vehicle 1000. For example, the battery 30 can serve as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 40 and a motor 50. The controller 40 is used to control the battery 30 to power the motor 50, for example, for starting, navigating and driving the vehicle 1000.

[0108] In some embodiments of the present application, the battery 30 can serve not only as an operating power source for the vehicle 1000 , but also as a driving power source for the vehicle 1000 , replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 1000 .

[0109] Please refer to Figure 2, which is an exploded view of a battery 30 provided in some embodiments of the present application. The battery 30 includes a housing 301 and a battery cell 302, and the battery cell 302 is accommodated in the housing 301. The housing 301 is used to provide a storage space for the battery cell 302, and the housing 301 can adopt a variety of structures. In some embodiments, referring to Figure 2, the housing 301 can include a first portion 3011 and a second portion 3012, and the first portion 3011 and the second portion 3012 cover each other, and the first portion 3011 and the second portion 3012 jointly define a storage space for accommodating the battery cell 302. The second portion 3012 may be a hollow structure with an opening at one end, and the first portion 3011 may be a plate-like structure, with the first portion 3011 covering the opening of the second portion 3012, so that the first portion 3011 and the second portion 3012 jointly define a storage space. The first portion 3011 and the second portion 3012 may also be hollow structures with an opening at one end, with the opening of the first portion 3011 covering the opening of the second portion 3012. Of course, the box 301 formed by the first portion 3011 and the second portion 3012 may have various shapes, such as a cylinder, a rectangular parallelepiped, etc.

[0110] The battery 30 may include a battery cell 302. There may be multiple battery cells 302, and the multiple battery cells 302 may be connected in series, in parallel, or in a hybrid connection. A hybrid connection refers to a combination of series and parallel connections among the multiple battery cells 302. The multiple battery cells 302 may be directly connected in series, in parallel, or in a hybrid connection, and then the entire battery 302 may be contained within the housing 301. Of course, the battery 30 may also be a battery module 30 formed by first connecting multiple battery cells 302 in series, in parallel, or in a hybrid connection, and then the multiple battery modules 30 are further connected in series, in parallel, or in a hybrid connection to form a complete battery 30, and then contained within the housing 301. The battery 30 may also include other structures, such as a busbar for electrically connecting the multiple battery cells 302.

[0111] In this application, battery cells 302 may include lithium-ion secondary batteries, lithium-ion primary batteries, lithium-sulfur batteries, sodium-lithium-ion batteries, sodium-ion batteries, or magnesium-ion batteries, etc., and this embodiment of the application does not limit this. Battery cells 302 may be cylindrical, flat, rectangular, or other shapes, and this embodiment of the application does not limit this. Battery cells 302 are generally divided into three types based on the packaging method: cylindrical battery cells, prismatic battery cells, and soft-pack battery cells, and this embodiment of the application does not limit this.

[0112] Battery cell 302 includes a housing, an electrode assembly, and an electrolyte. The housing houses the electrode assembly and electrolyte. The electrode assembly consists of a positive electrode sheet, a negative electrode sheet, and a separator. Battery cell 302 primarily operates by the movement of metal ions between the positive and negative electrode sheets. The separator can be made of any material, for example, polypropylene or polyethylene.

[0113] A positive electrode sheet generally includes a positive current collector and a positive active material layer. The positive active material layer is directly or indirectly coated on the positive current collector. The uncoated positive current collector protrudes from the coated positive current collector, serving as the positive tab. For lithium-ion batteries, for example, the positive current collector can be made of aluminum, and the positive active material layer can be made of lithium cobalt oxide, lithium iron phosphate, ternary lithium, or lithium manganese oxide.

[0114] A negative electrode sheet generally includes a negative electrode current collector and a negative electrode active material layer. The negative electrode active material layer is directly or indirectly coated on the negative electrode current collector. The negative electrode current collector not coated with the negative electrode active material layer protrudes from the negative electrode current collector coated with the negative electrode active material layer, and the negative electrode current collector not coated with the negative electrode active material layer serves as the negative electrode tab. The negative electrode current collector can be made of copper, and the negative electrode active material layer can be made of carbon, silicon, or other materials.

[0115] To ensure that high currents can pass without melting, multiple positive electrode tabs are stacked together, and multiple negative electrode tabs are stacked together. The electrode assembly can be a wound structure or a laminated structure, but the embodiments of the present application are not limited thereto.

[0116] As shown in FIG. 1 , an embodiment of the present application provides a battery mounting rack 10 . The battery mounting rack 10 of the embodiment of the present application is used to mount a battery 30 on a frame 60 of a vehicle 1000 .

[0117] 3 and 4 , the battery mounting rack 10 includes: a first rack 2A, the first rack 2A includes a plurality of extensions 2 arranged at intervals along a first direction X and a plurality of battery mounting spaces 4 arranged sequentially along the first direction X, the battery mounting space 4 being defined between two adjacent extensions 2 along the first direction X, and a battery mounting structure 3 for mounting a battery 30 in the battery mounting space 4 being provided on the battery mounting rack 10.

[0118] It is worth noting that the battery mounting frame 10 of the embodiment of the present application can be used for chassis-type battery swapping of the vehicle 1000. The battery swapping under frame refers to a method of realizing vehicle energy replenishment by flexibly replacing the battery swapping battery system installed under the chassis of the whole vehicle. Among them, the swappable battery system refers to a power battery system (referred to as battery 30 in this application) that is replaced as a whole during the battery swapping process of the vehicle 1000. Exemplarily, the battery swapping battery system generally includes: a power battery, a battery management system, a battery swapping electrical interface, a battery swapping cooling interface, and a battery swapping mechanical interface, etc., which can be charged and discharged in a non-vehicle state. The terms and definitions of the embodiments of the present application can be referred to GB / T 19596 Electric Vehicle Terminology.

[0119] 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 set to correspond to only one battery mounting space 4, or multiple batteries 30 can be set to correspond to one battery mounting space 4 at the same time. In other words, the specific mounting method depends on the shape of the battery 30 and is not limited here.

[0120] The phrase "a battery mounting frame 10 is provided with a battery mounting structure 3 for mounting a battery 30 on a battery mounting space 4" means that the battery mounting frame 10 is provided with a battery mounting structure 3 that can be connected to the battery 30. When the battery 30 is connected to the battery mounting structure 3, at least a portion of the battery 30 can be accommodated in the battery mounting space 4, presenting a mounted state. In an embodiment of the present application, the battery mounting frame 10 includes a plurality of battery mounting spaces 4, and the battery mounting frame 10 is provided with a battery 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 battery 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. The "correspondence" in the setting of the battery mounting structure 3 corresponding to the battery mounting space 4 refers to the correspondence between the two, including but not limited to the correspondence in position.

[0121] But not limited to this, 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 second direction Y are used to mount the same battery 30, the battery mounting structures 3 corresponding to these two battery mounting spaces 4 can be set to be independent of each other, or can also be set to a linkage form, so that when the same battery 30 is mounted, the linkage form of the battery mounting structure 3 is conducive to improving the battery replacement efficiency.

[0122] When using such a battery mounting rack 10 to install a battery 30 on a vehicle, since the battery mounting rack 10 includes multiple battery mounting spaces 4, and a battery mounting structure 3 is provided on the battery mounting rack 10, each battery mounting space 4 can be used to mount a battery 30, so that a battery 30 can be mounted separately on each battery mounting space 4. In this way, the battery mounting rack 10 can have the function of installing multiple batteries 30. When replacing the battery, only the exhausted battery 30 can be replaced, while the unexhausted battery 30 can be retained, thereby improving the energy utilization rate of the battery 30 and improving the energy waste problem.

[0123] Furthermore, because the battery mounting space 4 is defined between two adjacent extensions 2, the extensions 2 protect the batteries 30, alleviating collisions between batteries 30 within two adjacent battery mounting spaces 4 along the first direction, as well as improving heat transfer between batteries 30 within two adjacent battery mounting spaces 4 along the first direction, thereby enhancing the operational reliability of the batteries 30. Specifically, the portion of the battery 30 housed within the battery mounting space 4 is protected by the extensions 2 on both sides, mitigating collisions and heat transfer between batteries 30 within two adjacent battery mounting spaces 4.

[0124] The battery mounting structure 3 can be disposed on the extension portion 2, or it can be disposed off the extension portion 2, without limitation. The distribution position, number, and structural form of the battery mounting structure 4 can be flexibly designed to meet the mounting requirements of the battery 30. The structure of the battery mounting structure 3 is not limited, and can include, but is not limited to, mounting slots, mounting holes, mounting protrusions, mounting pins, or mounting screws, etc., without limitation.

[0125] For example, when the battery mounting rack 10 is used to mount the battery 30 on the vehicle 1000, the first direction X is set as the longitudinal direction of the vehicle 1000, and the battery mounting structure 3 is set on the extension portion 2. In this case, neither the battery mounting structure 3 nor the extension portion 2 occupies the space of the battery 30 in the width direction of the vehicle 1000, thereby increasing the size of the battery mounting space 4 in the width direction of the vehicle 1000, thereby increasing the size of the battery 30 in the width direction of the vehicle 1000, and thus facilitating an improvement in the size-energy density of the battery 30. Furthermore, setting the first direction X as the longitudinal direction of the vehicle 1000, due to the relatively large longitudinal space of the vehicle 1000, further facilitates increasing the size or number of the battery mounting spaces 4 in the longitudinal direction of the vehicle 1000, thereby further improving the size-energy density or number of the batteries 30.

[0126] At the same time, multiple extensions 2 are spaced apart and distributed along the first direction X, and the battery mounting space 4 is limited between two adjacent extensions 2 along the first direction X, so that the number of battery mounting spaces 4 can be adjusted by increasing or decreasing the number of extensions 2, that is, by flexibly setting the number of extensions 2, so that the battery mounting rack 10 has high expandability, so that the battery mounting rack 10 can have the function of mounting multiple batteries 30 in the first direction X, that is, realize the multi-pack mounting function, thereby improving the vehicle 1000's range of a single battery replacement.

[0127] According to the battery mounting rack 10 of the embodiment of the present application, it is capable of mounting multiple batteries 30 in a first direction X, i.e., realizing a multi-pack mounting function. When the battery mounting rack 10 is used in a vehicle 1000, the first direction X can be set to the length of the vehicle 1000, so that the battery mounting rack 10 is capable of mounting multiple batteries 30 along the length of the vehicle 1000. This helps increase the number of batteries 30 that can be arranged on the vehicle 1000 and also helps increase the size of the battery mounting space 4 in the length and width directions of the vehicle 1000, thereby increasing the size and energy density of the batteries 30. Furthermore, the battery mounting space 4 is defined between two adjacent extensions 2 along the first direction X. The extensions 2 can be used to protect the batteries 30, thereby reducing problems such as collision and heat transfer between the batteries 30 in two adjacent battery mounting spaces 4 along the first direction X.

[0128] In some embodiments, the lengths of at least two battery mounting spaces 4 on the first rack 2A in the first direction X are the same.

[0129] Therefore, it is convenient to install batteries 30 of the same specification in at least two battery mounting spaces 4 with the same length in the first direction X, so that the battery 30 can be installed in any one of the battery mounting spaces 4, thereby improving installation efficiency and installation flexibility.

[0130] In some embodiments, the lengths of at least two battery mounting spaces 4 on the first rack 2A in the first direction X are inconsistent.

[0131] Thus, in order to facilitate the installation of batteries 30 of different specifications in at least two battery mounting spaces 4 of inconsistent lengths in the first direction X, batteries 30 of different specifications can be installed in battery mounting spaces 4 of corresponding sizes respectively, so that the setting of the battery mounting space 4 can match the specifications of the corresponding battery 30, thereby reducing the waste of installation space and enabling the battery mounting rack 10 to install at least two batteries 30 of different specifications.

[0132] It is worth noting that the lengths of all battery mounting spaces 4 arranged along the first direction X on the first rack 2A can be uniform, non-uniform, or some uniform and some non-uniform. This can be flexibly configured. When all battery mounting spaces 4 arranged along the first direction X on the first rack 2A are configured such that at least two battery mounting spaces 4 have the same length in the first direction X, and at least two battery mounting spaces 4 have non-uniform lengths in the first direction X, this can meet the flexible installation requirements of batteries 30 of the same specification, as well as the installation requirements of batteries 30 of different specifications.

[0133] In some embodiments, as shown in Figures 3 and 4, the battery mounting rack 10 includes two first racks 2A spaced apart along the second direction Y, each first rack 2A includes a plurality of battery mounting spaces 4 arranged in sequence along the first direction X, and the second direction Y intersects with the first direction X, such as at an obtuse angle, an acute angle, or a right angle.

[0134] Therefore, by setting up the battery mounting rack 10 to include two first racks 2A, and each first rack 2A includes a plurality of battery mounting spaces 4 arranged in sequence along the first direction X, so that each first rack 2A has the function of mounting multiple batteries 30 in the first direction X, and the two first racks 2A are arranged at intervals along the second direction Y, which can make full use of the space in the second direction Y to increase the number of batteries 30 that can be mounted on the battery mounting rack 10, which is beneficial to improve the cruising range of the vehicle 1000 after a single battery replacement.

[0135] When the battery mounting rack 10 is mounted on the vehicle frame 60, the first direction X can be set as the length direction of the frame 60, and the second direction Y can be set as the width direction of the frame 60. Since the two first racks 2A are spaced apart along the second direction Y, which is equivalent to being spaced apart along the width direction of the frame 60, the space between the two first racks 2A can be used to avoid the beam 20 of the frame 60, so that the batteries 30 can be distributed on both sides of the width of the beam 20. In other words, the battery mounting rack 10 has a double-sided mounting space configuration, which fully utilizes the bottom space of the vehicle 1000 and increases the number of batteries 30 that can be mounted. In the embodiment of the present application, the length direction of the frame 60, the length direction of the vehicle 1000, and the length direction of the beam 20 are all consistent, and the width direction of the frame 60, the width direction of the vehicle 1000, and the width direction of the beam 20 are all consistent.

[0136] In some embodiments, as shown in Figures 3 and 4, the extension portions 2 in the two first frames 2A are arranged one-to-one along the second direction Y, and the length extension directions of the two corresponding extension portions 2 are the same, and the orthographic projections of the two extension portions 2 along the length extension directions of the extension portions 2 coincide.

[0137] As a result, the corresponding battery mounting spaces 4 defined along the second direction Y on the two first racks 2A are of the same size and positioned correspondingly. Therefore, when the battery mounting rack 10 is used to mount a large, relatively regularly shaped battery 30, the two side portions of the battery 30 can respectively cooperate with the two corresponding battery mounting spaces 4 provided along the second direction Y. In this way, the two corresponding battery mounting spaces 4 provided along the second direction Y can be used to mount a single large battery 30, thereby improving the energy density of the installed battery 30. Furthermore, when the extension portion 2 is provided with a battery mounting structure 3, the two extension portions 2 corresponding in position along the second direction Y can respectively support the two side portions of the large battery 30, thereby improving the force balance and mounting stability of the battery 30.

[0138] In some embodiments, as shown in FIG. 3 and FIG. 4 , the first direction X is perpendicular to the second direction Y, the length extension direction of the extension portion 2 is the second direction Y, and the battery mounting spaces 4 on the two first racks 2A are symmetrically arranged.

[0139] Thus, by configuring the battery mounting rack 10 to include two first racks 2A, each first rack 2A including a plurality of battery mounting spaces 4 sequentially arranged along the first direction X, each first rack 2A is capable of mounting a plurality of batteries 30 in the first direction X. Furthermore, the two first racks 2A are spaced apart along the second direction Y, making full use of the space in the second direction Y to increase the number of batteries 30 that can be mounted on the battery mounting rack 10, thereby improving the range of the vehicle 1000 per single battery swap. The battery mounting spaces 4 on the two first racks 2A are symmetrically arranged, allowing the ends of symmetrically shaped and larger batteries 30 to be mounted correspondingly in the two symmetrically arranged battery mounting spaces 4, thus meeting the mounting requirements for large-sized batteries 30. Furthermore, the batteries 30, or the local distribution of the batteries 30, installed in the symmetrical battery mounting spaces 4 are more evenly distributed, and the force applied to the battery mounting rack 10 can be more evenly distributed, which is beneficial for improving the structural stability of the battery mounting rack 10.

[0140] When the battery mounting rack 10 is installed on the vehicle frame 60, the first direction X can be set as the length direction of the vehicle frame 60, and the second direction Y can be set as the width direction of the vehicle frame 60. Since the two first racks 2A are arranged at intervals along the second direction Y, the interval between the two first racks 2A can be used to avoid the vehicle beam 20, so that the batteries 30 can be distributed on both sides of the vehicle beam 20, and each side of the vehicle beam 20 can be mounted with multiple batteries 30 arranged along the length direction of the vehicle frame 60, so that the battery mounting rack 10 has multiple mounting spaces on both sides.

[0141] In some embodiments, as shown in Figures 3 and 4 , the battery mounting rack 10 further includes a second rack 1 , which connects two first racks 2A spaced apart along a second direction Y. The second rack 1 includes a beam avoidance groove 13 , which has an opening extending along the first direction X. For example, the first direction X can be set to coincide with the length direction of the beam 20 .

[0142] Therefore, by setting the second frame 1, the two first frames 2A can be connected into an integral structure through the second frame 1. In this way, for example, when the second frame 1 is fixed to the vehicle frame 60, the battery mounting frame 10 can be fixed, so that each first frame 2A reaches the use position, thereby reducing the difficulty of assembling the battery mounting frame 10. At the same time, the beam avoidance groove 13 of the second frame 1 has an opening that passes through along the first direction X, so that a part of the vehicle beam 20 can extend into the beam avoidance groove 13, so that the beam avoidance groove 13 can avoid the vehicle beam 20, avoid interference between the battery mounting frame 10 and the vehicle beam 20, and improve the compactness of the cooperation between the battery mounting frame 10 and the vehicle beam 20, which is beneficial to utilize the space near the vehicle beam 20 to set the battery 30, thereby facilitating the increase in the size and dimensional energy density of the battery 30.

[0143] In addition, the top of the beam avoidance groove 13 can be opened, so that the main body 1 can be pushed upward from the bottom to allow the beam 20 to enter the beam avoidance groove 13, thereby reducing the difficulty of assembling the battery mounting bracket 10 to the vehicle frame 60. The battery mounting bracket 10 can be subsequently installed on the already assembled vehicle frame 60, making the battery mounting bracket 10 suitable for use in a variety of vehicle models. The present application is not limited to this. For example, in other embodiments of the present application, the beam avoidance groove 13 can also be set to be open at the bottom. In this case, the battery mounting bracket 10 and the frame 60 can be assembled simultaneously during the process of assembling the frame 60.

[0144] In some embodiments, as shown in Figure 4, the second frame 1 includes a first main body wall 11, which is multiple and spaced apart along the first direction X to form a battery avoidance opening 14 between two adjacent first main body walls 11. The battery avoidance opening 14 is arranged opposite to the battery mounting space 4 along the second direction Y.

[0145] Therefore, by providing the battery avoidance opening 14, when a larger-sized battery 30 is installed in the battery mounting space 4, the battery 30 can be avoided through the battery avoidance opening 14 to avoid interference between the battery 30 and the second rack 1. For example, when the battery mounting rack 10 is installing a large-sized and regularly-shaped battery 30, the portion of the battery 30 corresponding to the first rack 2A can extend into the battery mounting space 4, and the portion of the battery 30 corresponding to the second rack 1 can extend into the battery avoidance opening 14. In this way, it is convenient to install a larger-sized battery 30, which is beneficial to improve the energy density of the installed battery 30.

[0146] In some embodiments, as shown in Figures 4 and 5, the second frame 1 also includes a second main wall 12, which extends along the first direction X. There are two second main walls 12 and are connected on both sides of each first main wall 11 at intervals along the second direction Y, so that the vehicle beam avoidance groove 13 is defined between the first main wall 11 and the two second main walls 12. The first frame 2A is arranged on the side of the second main wall 12 away from the first main wall 11 in the second direction Y, and each extension portion 2 is connected to the second main wall 12.

[0147] Therefore, by setting the second main body wall 12, multiple first main body walls 11 and second main body walls 12 can be connected into an integral structure, thereby reducing the difficulty of setting up the second frame 1, and facilitating the definition of the extension direction of the vehicle beam avoidance groove 13, so that it extends along the first direction X, wherein the first frame 2A is arranged on the side of the second main body wall 12 away from the first main body wall 11 in the second direction Y, and each extension part 2 is connected to the side of the second main body wall 12 away from the first main body wall 11 in the second direction Y to avoid interference between the extension part 2 and the vehicle beam 20, and to facilitate the expansion of the battery mounting space 4 in the second direction Y, so as to facilitate the improvement of the size and dimensional energy density of the battery 30.

[0148] In some embodiments, as shown in Figures 4 and 5 , the height of the extension portion 2 decreases as it moves away from the second main body wall 12. It should be noted that "decreasing" can mean a gradual decrease or a step-wise decrease. Here, the ends of the extension portion 2 in the height direction Z are defined as the upper and lower ends. When the height direction Z of the extension portion 2 coincides with the height direction of the vehicle 1000, the ends of the extension portion 2 in the height direction Z also constitute the upper and lower ends in the direction of gravity.

[0149] Therefore, by setting the height of the extension portion 2 to decrease in the direction away from the second main body wall 12 in the second direction Y, the height of the extension portion 2 in the area away from the second main body wall 12 is smaller.

[0150] That is to say, the height of the end portion of the extension portion 2 connected to the second main body wall 12 is relatively large, while the height of the end portion of the extension portion 2 away from the second main body wall 12 is relatively small, thereby enhancing the connection strength between the extension portion 2 and the second main body wall 12, improving the reliability of the extension portion 2 for mounting the battery 30, and reducing the weight of the extension portion 2, thereby reducing the load of the vehicle 1000.

[0151] In some embodiments, as shown in Figures 4 and 5 , the lower edge of the extension portion 2 extends along a horizontal line, the battery mounting structure 3 is located at the lower edge of the extension portion 2, and the upper edge of the extension portion 2 decreases in a direction away from the second main body wall 12. It is worth noting that the "decreasing trend" can be a gradual decrease or a step-by-step decrease.

[0152] Therefore, by setting the lower edge of the extension portion 2 to extend along the horizontal line, it is beneficial for the battery mounting structures 3 to be located at the same horizontal height, thereby facilitating the mounting operation of the battery 30.

[0153] For example, when a tool is extended upward to the position of the battery mounting structure 3 to mount and connect the battery mounting structure 3 to the battery 30, the raised position of the tool is lower than the extension portion 2, thereby reducing the tool's lifting height. In addition, the tool does not need to be inserted between the battery 30 and the extension portion 2. There is no need to increase the gap between the battery 30 and the extension portion 2 to meet the tool insertion requirement, thereby reducing space waste. The saved space can be used to further increase the size of the battery 30, thereby further improving the size energy density of the battery 30. This makes it easier to mount the battery 30.

[0154] At the same time, the upper edge of the extension portion 2 tends to decrease in the direction away from the second main body wall 12, so that the height of the end of the extension portion 2 connected to the second main body wall 12 is relatively large, while the height of the end of the extension portion 2 away from the second main body wall 12 is relatively small, thereby enhancing the connection strength between the extension portion 2 and the second main body wall 12, improving the reliability of the extension portion 2 for mounting the battery 30, and reducing the weight of the extension portion 2, thereby reducing the load of the vehicle 1000.

[0155] For example, referring to Figures 4 and 5 , a mounting edge 21 is provided at the lower edge of the extension portion 2. When the battery mounting structure 3 is located at the lower edge of the extension portion 2, it can be provided on the mounting edge 21. In this case, the mounting edge 21 can be arranged to extend horizontally. This facilitates the battery mounting structures 3 to be located at the same level, thereby facilitating the mounting operation of the battery 30.

[0156] In some embodiments, as shown in FIG. 4 and FIG. 5 , a vehicle beam connecting structure 15 is provided on at least one of the first frame 2A and the second frame 1 .

[0157] The phrase "at least one of the first frame 2A and the second frame 1 is provided with a beam connection structure 15" means that the beam connection structure 15 can be provided on the first frame 2A, or the second frame 1, or both the first frame 2A and the second frame 1. The specific structure of the beam connection structure 15 is not limited, and can be, for example, a threaded hole, a connection hole, or a snap-fit ​​structure.

[0158] In this way, since the second frame 1 cooperates with the vehicle beam 20 through the vehicle beam avoidance groove 13, the second frame 1 and the first frame 2A can both have a portion close to the vehicle beam 20. In this way, by setting the vehicle beam connection structure 15 to be connected to the vehicle beam 20, it is easy to install the battery mounting frame 10 to the vehicle frame 60.

[0159] In some embodiments, at least one of a heat-insulating structure, a heat-dissipating structure, and a buffer structure is provided on a side of the extension portion 2 facing the battery mounting space 4 .

[0160] In the above technical solution, a heat-insulating structure is provided to insulate the battery 30 and improve the heat transfer effect between two adjacent batteries 30. The heat-insulating structure includes but is not limited to heat-insulating cotton, heat-insulating film, or other heat-insulating structures, which are not limited here.

[0161] By providing a heat dissipation structure, the battery 30 is cooled, thereby improving overheating of the battery 30 and reducing the risk of thermal runaway of the battery 30. The heat dissipation structure includes but is not limited to a radiator, a cooler, a fan, or other heat dissipation structures, which are not limited here.

[0162] By providing a buffer structure to provide a buffer for the battery 30, the rigid contact between the battery 30 and the buffer portion is improved, thereby protecting the battery 30 and extending the service life of the battery 30. The buffer structure includes, but is not limited to, sponges, rubber parts, elastic parts, and other buffer structures, which are not limited here.

[0163] In some embodiments, as shown in FIG. 4 and FIG. 5 , the battery mounting structure 3 is provided on the extension portion 2 .

[0164] In the above technical solution, by arranging the battery mounting structure 3 on the extension portion 2, the battery mounting structure 3 only occupies space in the first direction X, thereby avoiding the battery mounting structure 3 from occupying space in other directions, such as the width and height directions of the vehicle 1000. This facilitates increasing the size of the battery 30 in these relatively cramped dimensions (such as the width and height directions of the vehicle 1000), thereby improving the size and energy density of the battery 30. Moreover, the relatively large space on the extension portion 2 facilitates flexible arrangement of the distribution position, number, and structural form of the battery mounting structure 3 on the extension portion 2, thereby improving the mounting strength of large-sized batteries 30.

[0165] In some embodiments, as shown in FIG. 4 and FIG. 5 , a battery mounting structure 3 is arranged on a side of the extension portion 2 facing the battery mounting space 4 .

[0166] Thus, by arranging the battery mounting structure 3 on the side of the extension portion 2 facing the battery mounting space 4, the battery mounting structure 3 corresponds to the battery mounting space 4 that the battery mounting structure 3 faces, and is used to mount the battery 30 in the battery mounting space 4 that the battery mounting structure 3 faces. This makes it possible to clearly identify the corresponding relationship between the battery mounting structure 3 and the battery mounting space 4. When the battery 30 is inserted into the battery mounting space 4, it can be connected to the battery mounting structure 3 facing the battery mounting space 4, thereby conveniently achieving the mounting of the battery 30. Moreover, when there are multiple battery mounting spaces 4, the battery mounting structures 3 corresponding to different battery mounting spaces 4 are arranged at different positions and do not interfere with each other. This allows the battery mounting structures 3 corresponding to each battery mounting space 4 to have sufficient space for flexible arrangement, so that the battery mounting structures 3 can more easily and reliably mount the battery 30.

[0167] In some embodiments, as shown in Figures 4 and 5, at least one extension portion 2 located in the middle of the multiple extension portions 2 is a common extension portion 2a, and the common extension portion 2a has battery mounting spaces 4 on both sides in the first direction X, and battery mounting structures 3 are arranged on both sides of the battery mounting spaces 4 facing both sides of the common extension portion 2a.

[0168] It is worth noting that "at least one central extension portion 2 among the multiple extension portions 2 is a common extension portion 2a" means that, among the multiple extension portions 2 arranged at intervals along the first direction X, at least one of the remaining extension portions 2, excluding the two extension portions 2 on either side, is a common extension portion 2a. For example, when four extension portions 2 are arranged at intervals along the first direction X, at least one of the two central extension portions 2 is a common extension portion 2a. Furthermore, two adjacent battery mounting spaces 4 along the first direction X are separated by the common extension portion 2a.

[0169] Thus, when the number of battery mounting spaces 4 spaced apart along the first direction X is fixed, the number of extensions 2 spaced apart along the first direction X can be reduced, thereby facilitating cost reduction and reducing the load of the vehicle 1000. For example, in the minimum case, the number of extensions 2 spaced apart along the first direction X can be one greater than the number of battery mounting spaces 4, i.e., only one extension 2 is provided between two adjacent battery mounting spaces 4 along the first direction X, thereby facilitating cost reduction and reducing the load of the vehicle 1000.

[0170] However, the present application is not limited to this. For example, two extension portions 2 may be provided between two adjacent battery mounting spaces 4 along the first direction X. In this way, each extension portion 2 may only correspond to the battery mounting space 4 on one side to arrange the battery mounting structure 3, thereby reducing the bearing force of each extension portion 2 on the battery 30 and improving the mounting reliability of the battery 30.

[0171] For example, referring again to FIG. 4 , the battery mounting rack 10 includes four extensions 2 spaced apart along a first direction X. The four extensions 2 define three battery mounting spaces 4, with the two middle extensions 2 serving as a common extension 2a. Of course, the number of battery mounting spaces 4 described above is merely illustrative. For example, the battery mounting rack 10 may also include two, three, five, or more battery mounting spaces 4 disposed along the first direction X, depending on the specific requirements of the vehicle 1000.

[0172] Furthermore, the number of extensions 2 may not be simply one more than the number of battery mounting spaces 4. For example, three battery mounting spaces 4 may be defined by five or six extensions 2. However, it is understood that when the number of extensions 2 is not simply one more than the number of battery mounting spaces 4, the number of extensions 2 used can be reduced, thereby reducing the cost and weight of the battery mounting rack 10.

[0173] At the same time, by arranging the battery mounting structures 3 on both sides of the battery mounting spaces 4 on both sides of the common extension part 2a, the battery 30 can be mounted in the battery mounting spaces 4 on both sides of the common extension part 2a, and the battery mounting structures 3 on both sides of the common extension part 2a are integrated on the common extension part 2a, which helps to reduce the difficulty of setting up the battery mounting structures 3.

[0174] In some embodiments, the battery mounting structures 3 on both sides of the common extension portion 2a in the first direction X are misaligned in their orthographic projections on a projection plane perpendicular to the first direction X. For example, the distance from any battery mounting structure 3 on one side of the common extension portion 2a to the second rack 1 in the second direction Y is different from the distance from any battery mounting structure 3 on the other side of the common extension portion 2a to the second rack 1 in the second direction Y.

[0175] Therefore, by setting the battery mounting structures 3 on both sides of the common extension part 2a to be misaligned in the projection on the projection plane perpendicular to the first direction X, the force distribution of the common extension part 2a is made more reasonable. When the batteries 30 in the battery mounting spaces 4 on both sides of the common extension part 2a are respectively connected to the battery mounting structures 3 on both sides of the common extension part 2a, stress concentration can be reduced to cause deformation, fracture and other problems in the common extension part 2a, thereby improving the service life of the common extension part 2a and improving the mounting reliability of the battery 30.

[0176] In some embodiments, referring to FIG. 4 and FIG. 5 , the extension portion 2 includes a mounting edge 21 protruding toward the battery mounting space 4 , and the battery mounting structure 3 is located on the mounting edge 21 .

[0177] Therefore, by setting the mounting edge 21, it is helpful to reduce the difficulty of setting the battery mounting structure 3, and it is easy to realize that the battery mounting structure 3 is located on the side of the extension part 2 facing the battery mounting space 4. Moreover, the mounting edge 21 can play a certain direct or indirect supporting role on the battery 30 to enhance the mounting stability of the battery 30.

[0178] In some embodiments, as shown in FIG. 4 and FIG. 5 , a battery mounting structure 3 is provided on the extension portion 2 on both sides of the battery mounting space 4 in the first direction X.

[0179] Thus, both sides of the battery 30 mounted in the battery mounting space 4 can be respectively connected to the battery mounting structures 3 of the extension parts 2 on both sides of the battery mounting space 4 in the first direction X, so that the extension parts 2 on both sides of the battery mounting space 4 in the first direction X can play the role of supporting the battery 30 in the battery mounting space 4, and the battery mounting structures 3 on both sides can disperse the force to reduce stress concentration and cause deformation, fracture and other problems of the extension part 2, thereby improving the service life of the extension part 2 and improving the mounting reliability of the battery 30.

[0180] In some embodiments, the battery mounting structures 3 on both sides of the battery mounting space 4 in the first direction X are misaligned in their orthographic projections on a projection plane perpendicular to the first direction X. For example, the distance from any battery mounting structure 3 on one side of the battery mounting space 4 to the second rack 1 in the second direction Y is different from the distance from any battery mounting structure 3 on the other side of the battery mounting space 4 to the second rack 1 in the second direction Y.

[0181] Therefore, by setting the battery mounting structures 3 on both sides of the battery mounting space 4 to be staggered in the projection on the projection plane perpendicular to the first direction X, it is further beneficial to disperse the force on the battery mounting structures 3 on both sides, and further improve the problems of deformation and fracture of the extension part 2 caused by stress concentration.

[0182] In addition, when the battery mounting structures 3 on both sides of the common extension portion 2a in the first direction X are misaligned in their orthographic projections on the projection plane perpendicular to the first direction X, and the battery mounting structures 3 on both sides of the battery mounting space 4 in the first direction X are misaligned in their orthographic projections on the projection plane perpendicular to the first direction X, multiple extension portions 2 can be constructed into the same structure, which is conducive to simplifying the structure, facilitating processing, reducing costs, and improving assembly efficiency.

[0183] In some embodiments, a plurality of battery mounting structures 3 are provided on the side of the extension portion 2 facing the battery mounting space 4, with at least two battery mounting structures 3 spaced apart along the length direction of the extension portion 2 (e.g., the second direction Y shown in FIG. 4 ). This facilitates full utilization of the space along the length direction of the extension portion 2, allowing for the arrangement of a greater number of battery mounting structures 3, thereby enhancing the mounting stability of the battery 30 or increasing the number of batteries 30 mounted within the battery mounting space 4.

[0184] In some embodiments, the extension portion 2 is plate-shaped, and the thickness direction is the first direction X, the length direction is the second direction Y, and the width direction is the height direction Z.

[0185] Therefore, by setting the extension part 2 to be plate-shaped and defining the first direction X and the second direction Y as above, the battery mounting space 4 can be located on one side or both sides in the thickness direction of the extension part 2, so that the length structural characteristics of the extension part 2 can be fully utilized to define the battery mounting space 4, so that the space occupied by the extension part 2 is smaller, and the defined battery mounting space 4 is larger.

[0186] In addition, the battery mounting frame 10 defines a plurality of battery mounting spaces 4 in the thickness direction of the extension portion 2. The distance between two adjacent battery mounting spaces 4 in the thickness direction of the extension portion 2 is the thickness of the extension portion 2, so that the gap between two adjacent battery mounting spaces 4 is smaller, so that more battery mounting spaces 4 can be set in the thickness direction of the extension portion 2, which is conducive to further improving space utilization.

[0187] For example, when the thickness direction of the extension portion 2 is the same as the length direction of the vehicle 1000, and the length direction of the extension portion 2 is the same as the width direction of the vehicle 1000, the mounting space of the battery 30 can be expanded in the length direction and width direction of the vehicle 1000, thereby improving the cruising range of the vehicle 1000 per single battery replacement.

[0188] In some embodiments, referring to FIG. 5 , a reinforcing rib 22 and / or a weight-reducing structure 23 is provided on the extension portion 2 .

[0189] Therefore, by providing the reinforcing ribs 22 , the structural strength of the extension portion 2 is enhanced, the deformation problem of the extension portion 2 due to stress is improved, and the reliability of the extension portion 2 for mounting the battery 30 is improved.

[0190] The reinforcing ribs 22 may include but are not limited to strip-shaped reinforcing protrusions or partially thickened portions of the extension 2 , and the structural form of the reinforcing ribs 22 is not limited, such as linear, curved, or cross-shaped.

[0191] For example, when a battery 30 is mounted on the battery mounting structure 3 of the extension part 2, the position of the battery mounting structure 3 of the extension part 2 is subjected to concentrated force and is prone to deformation and damage. Therefore, at least part of the reinforcing ribs 22 can be arranged corresponding to the battery mounting structure 3, thereby reducing the number of reinforcing ribs 22 while better improving the structural strength of the extension part 2 and improving the reliability of the extension part 2 for mounting the battery 30.

[0192] For example, when multiple battery mounting structures 3 are provided on the extension portion 2, at least some of the reinforcing ribs 22 are arranged between two adjacent battery mounting structures 3. When batteries 30 are mounted on the battery mounting structures 3 on the extension portion 2, the battery mounting structures 3 on the extension portion 2 are subjected to concentrated stress, making them susceptible to deformation and damage. By arranging at least some of the reinforcing ribs 22 between two adjacent battery mounting structures 3, the structural strength of the extension portion 2 between the two adjacent battery mounting structures 3 can be enhanced, improving the problem of stress concentration and fracture between the two adjacent battery mounting structures 3, and improving the reliability of the extension portion 2 for mounting the batteries 30.

[0193] The weight-reducing structure 23 is provided to reduce the weight of the extension portion 2, thereby facilitating a lightweight design of the extension portion 2. The "weight-reducing structure 23" may include, but is not limited to, weight-reducing holes, weight-reducing grooves, or thinning treatments, and is not limited here.

[0194] In addition, when the extension part 2 is provided with reinforcing ribs 22 and weight-reducing structures 23 at the same time, the weight of the extension part 2 increases due to the provision of reinforcing ribs 22, while the weight-reducing structures 23 can reduce the weight. In this way, the reliability and lightweight of the extension part 2 can be taken into account.

[0195] In some embodiments, referring to FIG. 4 , the first frame 2A further includes a reinforcing portion 5 , which connects at least two extending portions 2 .

[0196] This helps to enhance the overall structural strength of the battery mounting frame 10 , reduce deformation of the extension portion 2 caused by stress, and improve the mounting reliability of the battery 30 .

[0197] Exemplarily, the reinforcing portion 5 and the second frame 1 are disposed on both sides of the extending portion 2 in the second direction Y.

[0198] As a result, the two extensions 2 defining the battery mounting space 4 can be connected at both ends in the second direction Y by the second frame 1 and the reinforcement portion 5, respectively. This allows the structure surrounding the battery mounting space 4 to be formed into a ring shape, which provides greater structural strength, higher reliability for mounting the battery 30, and more comprehensive protection for the battery 30 from the circumference. Furthermore, the location of the battery mounting structure 3 can be flexibly selected.

[0199] In the second aspect, please refer to Figures 3 and 4. The present application provides a frame assembly 100, which includes a frame 60 and a battery mounting bracket 10 as in any of the above embodiments. The battery mounting bracket 10 is used to install the battery 30 to the frame 60. The first direction X is the length direction of the frame 60.

[0200] That is, the battery mounting bracket 10 is mounted on the vehicle frame 60 , and then the battery 30 is connected to the battery mounting structure 3 to realize the assembly of the battery 30 to the battery mounting bracket 10 , so that the battery mounting bracket 10 can be used to mount the battery 30 on the vehicle frame 60 .

[0201] Therefore, when using such a battery mounting rack 10 to install the battery 30 on the vehicle, since the battery mounting rack 10 includes a plurality of battery mounting spaces 4 arranged along the length direction of the frame 60, the battery mounting rack 10 can make full use of the space in the length direction of the frame 60 to install a larger number of batteries 30. Moreover, when replacing the battery, only the exhausted battery 30 can be replaced, while the unexhausted battery 30 can be retained, thereby improving the energy utilization rate of the battery 30 and improving the energy waste problem.

[0202] In some embodiments, the battery mounting frame 10 is disposed at the bottom of the vehicle frame 60, and the vehicle frame 60 includes a vehicle beam 20. A first frame 2A is provided on at least one side in the width direction of the vehicle beam 20, and at least a portion of the first frame 2A is higher than the bottom surface of the vehicle beam 20 of the vehicle frame 60 in the height direction Z of the vehicle frame 60, so that at least a portion of the battery mounting space 4 is higher than the bottom surface of the vehicle beam 20.

[0203] In the embodiment of the present application, the length direction of the vehicle frame 60, the length direction of the vehicle 1000, and the length direction of the vehicle beam 20 are all consistent, and the width direction of the vehicle frame 60, the width direction of the vehicle 1000, and the width direction of the vehicle beam 20 are all consistent. Among them, the vehicle beam 20 refers to: an intermediate beam located at the bottom of the vehicle 1000 and extending along the length direction of the vehicle 1000, also known as a vehicle bottom beam. It is worth noting that the specific structure of the vehicle beam 20 according to the embodiment of the present application is not limited. For example, in conjunction with Figures 3 and 4, it can include two longitudinal beams 201 extending along the length direction of the vehicle 1000 (for example, the first direction X shown in Figure 4) and at least one cross beam 202 extending along the width direction of the vehicle 1000 (for example, the second direction Y shown in Figure 4), the two longitudinal beams 201 are arranged at intervals along the width direction of the vehicle 1000, and the cross beam 202 is connected between the two longitudinal beams 201.

[0204] As a result, the battery mounting space 4 is not completely lower than the vehicle beam 20, but is at least partially higher than the bottom surface of the vehicle beam 20 and is located on at least one side in the width direction of the vehicle beam 20, so that the bottom space of the frame 60 can be fully utilized to arrange the extension part 2 and the battery mounting space 4, so as to facilitate mounting a larger battery 30 on the battery mounting frame 10, thereby improving the cruising range of the vehicle 1000 on a single battery replacement.

[0205] In some embodiments, the first racks 2A are symmetrically provided on both sides of the width direction of the vehicle beam 20. In other words, the first racks 2A are provided on both sides of the width direction of the vehicle beam 20, and the first racks 2A on both sides of the width direction of the vehicle beam 20 are symmetrically arranged. This simplifies the structure of the battery mounting rack 10, facilitates processing, and fully utilizes the space under the vehicle to mount more or larger batteries 30.

[0206] In a third aspect, the present application provides a vehicle 1000 , which includes a battery 30 and a frame assembly 100 as described in any of the above embodiments, wherein at least a portion of the battery 30 is accommodated in a battery mounting space 4 .

[0207] Thus, at least a portion of the battery 30 is accommodated in the battery mounting space 4, so that the battery 30 can be mounted on the vehicle 1000, thereby increasing the ground clearance of the battery 30 and the vehicle 1000. This also facilitates full utilization of the battery mounting space 4, thereby reducing the installation space occupied by the battery 30. Furthermore, this helps increase the number of mounted batteries 30, allowing replacement batteries 30 to be selected as needed, thereby reducing energy waste.

[0208] For example, the bottom of the battery mounting space 4 is open, so that the battery 30 can be inserted into the battery mounting space 4 from the bottom up, thereby facilitating the installation of the battery 30. Furthermore, the battery mounting space 4 can also be configured to be open at both the bottom and the top, thereby improving the space utilization of the battery 30 in the height direction, thereby increasing the height dimension and dimensional energy density of the battery 30.

[0209] In some embodiments, the battery 30 is detachably installed in any battery mounting space 4 .

[0210] Therefore, the battery 30 can be installed in any one of the battery mounting spaces 4. This can increase the versatility of the battery mounting space 4, thereby reducing the difficulty of mounting the battery 30 and improving the flexibility of the battery 30 replacement installation location selection.

[0211] The present application is not limited thereto. For example, in other embodiments, the battery 30 may be configured to be only removable and corresponding to the battery mounting space 4 of the size.

[0212] In some embodiments, as shown in FIG. 3 and FIG. 6 , the vehicle 1000 includes a plurality of batteries 30 arranged along a first direction X, and the plurality of batteries 30 are installed in a plurality of battery mounting spaces 4 in a one-to-one correspondence.

[0213] Thus, multiple batteries 30 are installed one by one in multiple battery mounting spaces 4, so that multiple batteries 30 arranged along the first direction X can be mounted and installed through the first frame 2A, that is, multi-pack mounting is achieved, thereby making full use of the space in the length direction of the vehicle 1000 to increase the number of batteries 30, so as to improve the cruising range of the vehicle 1000 in a single battery replacement.

[0214] In some embodiments, as shown in Figures 7 and 8, the battery 30 includes a battery upper part 30a and a battery lower part 30b, the battery upper part 30a is accommodated in the battery mounting space 4, and the battery 30 is provided with a mounting structure 30c at a position between the battery upper part 30a and the battery lower part 30b, and the mounting structure 30c is detachably connected to the battery mounting structure 3.

[0215] Thus, when the battery 30 is mounted on the battery mounting rack 10, the upper portion 30a of the battery can extend into the battery mounting space 4, and the extension portion 2 can be used to protect the upper portion 30a of the battery to reduce the risk of damage to the battery 30, thereby extending 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, which can reduce the height of the extension portion 2, thereby reducing the weight and cost of the battery mounting rack 10. Moreover, the mounting structure 30c is set at a position between the upper portion 30a of the battery and the lower portion 30b of the battery, so that the battery mounting structure 3 is located at the lower edge of the extension portion 2, which is conducive to the battery replacement operation as described above. Moreover, the mounting structure 30c is detachably connected to the battery mounting structure 3, which makes it easier to replace the battery 30 and improve the efficiency of battery replacement.

[0216] The connection method between the mounting structure 30c and the battery mounting structure 3 includes, but is not limited to, bolt connection, snap connection, plug connection, magnetic connection, etc.

[0217] In some embodiments, referring to Figures 7 and 8, in the first direction X, the size of the upper battery portion 30a is smaller than the size of the lower battery portion 30b, so as to form a step surface 30d between the upper battery portion 30a and the lower battery portion 30b, and the bottom of the battery mounting space 4 is open so that the upper battery portion 30a can extend from the bottom to the top into the battery mounting space 4, and the step surface 30d stops at the bottom of the extension portion 2, so that at least a portion of the upper battery portion 30a extends into the battery mounting space 4, and the lower battery portion 30b is located outside the battery mounting space 4.

[0218] It is worth noting that the term "step surface 30d abutting the bottom of extension portion 2" should be understood broadly, meaning that step surface 30d and extension portion 2 may be in direct or indirect contact to achieve the abutment effect. For example, a battery mounting structure 3 may be provided below extension portion 2, and mounting structure 30c may be provided on step surface 30d. When mounting structure 30c is coupled to battery mounting structure 3, step surface 30d abuts the bottom of extension portion 2.

[0219] Therefore, when the battery 30 is actually installed, the bottom of the extension portion 2 and the stepped surface 30d can be used as a stop to indicate that the battery 30 is properly installed when the upper portion 30a of the battery is extended upward from the bottom into the battery mounting space 4. This prevents the battery 30 from excessively extending into the battery mounting space 4 and causing impact with the vehicle bottom, thereby protecting the battery 30. In addition, setting the size of the lower portion 30b larger than that of the upper portion 30a can further increase the size of the battery 30 to a certain extent, thereby further improving the size and energy density of the battery 30.

[0220] In some embodiments, referring to Figures 9 and 10, the battery 30 includes two battery side portions 30e and a battery central portion 30f. In the width direction of the frame 60, 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 portions 30e, so as to form a clearance groove 30g between the two battery side portions 30e and the battery central portion 30f, which passes through the length direction of the frame 60 and has an open top for avoiding the vehicle beam 20. At least one of the battery side portions 30e and the battery central portion 30f is detachably connected to the battery mounting structure 3.

[0221] “At least one of the battery side portion 30e and the battery central portion 30f is detachably connected to the battery mounting structure 3” includes: the battery side portion 30e is detachably connected to the battery mounting structure 3, or the battery central portion 30f is detachably connected to the battery mounting structure 3, or the battery side portion 30e and the battery central portion 30f are respectively detachably connected to the corresponding battery mounting structure 3.

[0222] Among them, the battery side 30e can be detachably connected to the battery mounting structure 3 through the mounting structure 30c on the battery side 30e. The position of the mounting structure 30c on the battery side 30e is not limited, for example, it can be located in the middle, upper or lower part of the battery side 30e.

[0223] Among them, the battery central part 30f can be detachably connected to the battery mounting structure 3 through the mounting structure 30c on the battery central part 30f. The position of the mounting structure 30c on the battery central part 30f is not limited, for example, it can be located in the middle, upper or lower part of the battery central part 30f.

[0224] Among them, the connection methods of the battery side portion 30e and / or the battery central portion 30f with the battery mounting structure 3 through the mounting structure 30c include but are not limited to: connection by bolts, or snap connection, or plug-in connection, or magnetic attraction, etc.

[0225] Thus, the structure of the battery 30 is ingenious. By avoiding the vehicle beam 20 and fully utilizing the space on both sides of the width of the vehicle beam 20, the overall size of the battery 30 can be increased, thereby improving the size and energy density of the battery 30. At the same time, at least one of the battery side portion 30e and the battery center portion 30f is detachably connected to the battery mounting structure 3, thereby enhancing the design flexibility of the battery 30. Specifically, when both battery side portions 30e are connected to the battery mounting structure 3, or when both the battery side portions 30e and the battery center portion 30f are connected to the battery mounting structure 3, the installation stability of the battery 30 is improved.

[0226] For example, as shown in FIG10 , at least a portion of the beam 20 is located within the clearance groove 30 g and above the central portion 30 f of the battery. The two battery side portions 30 e can be located on both sides of the width direction of the beam 20 . In this way, the space on both sides of the width direction of the beam 20 can be fully utilized to arrange a larger battery 30 .

[0227] It is worth noting that the shape of the battery 30 in the embodiment of the present application is not limited thereto. For example, it may include only one battery side portion 30e, or include both a battery central portion 30f and a battery side portion 30e.

[0228] In recent years, battery swapping has become an important way for commercial electric vehicles to replenish energy in certain application scenarios such as logistics, docks, and mines. The construction of battery swap stations has also begun to accelerate. To ensure universal interchangeability of battery swaps, battery swap stations, charging equipment, and other battery swap facilities can be fully utilized to reduce resource waste.

[0229] This application proposes some embodiments of chassis-type battery swapping to improve the compatibility and interchangeability of battery swapping. However, the following embodiments are not limited to pure electric vehicles and can be used for reference in other types of battery swapping vehicles.

[0230] In some embodiments, the operating voltage range of the battery replacement system is: 400V~750V.

[0231] In some embodiments, the flatness of the battery swapping contact surface of the battery swapping system is ≤4mm. Specifically, the contact interface between the battery swapping system and the battery mounting frame should be a flat surface with no convex structures, and the flatness should be less than 4mm.

[0232] In some embodiments, the dimensional tolerance of the battery replacement system is within ±10 mm.

[0233] In some embodiments, the weight M1 of the vehicle and the battery charge Q in the battery swap system satisfy: 0kg<M1≤1400kg, 100kWh≤Q≤200kWh; or 1400kg<M1≤2800kg, 200kWh<Q≤400kWh; or 2800kg<M1≤4200kg, 400kWh<Q≤600kWh; or 4200kg<M1≤5600kg, 600kWh<Q≤800kWh.

[0234] In some embodiments, as shown in Figures 11 and 12, the battery swap system should be replaced on a vehicle with a corresponding envelope space, and the battery size in the battery swap system is indicated in Figures 13 and 14.

[0235] In some embodiments, referring to Figures 11-14, a safety gap L0 is reserved between the front and rear end faces of the battery replacement system and the entire vehicle, and L0 ≥ 50mm.

[0236] In some embodiments, referring to Figures 11-14, the dimension L of the battery replacement system along the vehicle length direction satisfies: 700mm≤L≤900mm; or 1500mm≤L≤1700mm; or 2300mm≤L≤2500mm; or 3100mm≤L≤3300mm.

[0237] In some embodiments, referring to Figures 11-14, the dimension W of the battery replacement system along the vehicle width direction satisfies: 2300mm≤W≤2550mm.

[0238] In some embodiments, referring to Figures 11-14, the total height H of the battery replacement system satisfies: H≤680mm.

[0239] In some embodiments, referring to Figures 11-14, the length dimension L1 of the upper boss of the battery replacement system (such as the upper part 30a of the battery) satisfies: 600≤L1≤700.

[0240] In some embodiments, referring to Figures 11-14, the width dimension W1 of the bosses on both sides of the upper layer of the battery replacement system (such as the upper part 30a of the battery side 30e) satisfies: W1≤805mm.

[0241] In some embodiments, referring to Figures 11-14, the width dimension W2 of the upper middle boss of the battery replacement system (such as the upper part 30a of the battery center part 30f) satisfies: W2≤640mm.

[0242] In some embodiments, referring to Figures 11-14, the height dimension H1 of the bosses on both sides of the upper layer of the battery replacement system (such as the upper part 30a of the battery side 30e) satisfies: H1≤300mm.

[0243] In some embodiments, referring to Figures 11-14, the height dimension H2 of the upper middle boss of the battery replacement system (such as the upper part 30a of the battery center part 30f) satisfies: H2≤150mm.

[0244] At present, the application scenarios of heavy-duty electric vehicles mainly include trunk logistics, medium and short-distance operations (such as urban waste transportation), and closed operation scenarios (such as ports). The power demand can be roughly divided into three types: 400-600kWh, 300-400kWh, and 150-200kWh. Based on this power series, it can be seen that the standard package solution can be flexibly matched to suit different scenarios. For example, if the power of the standard battery swap system is around 150-200kWh, three standard battery swap battery systems (referred to as three packages), or two standard battery swap battery systems (referred to as double packages), or a single standard battery swap battery system (referred to as single package) can be used to meet the power demand.

[0245] Currently, the main models of heavy-duty electric trucks include: 6x4 tractor trucks, 4x2 tractor trucks, 8x4 dump trucks, 6x4 dump trucks, 4x2 cargo trucks, and 6x4 cargo trucks. The 6x4 tractor trucks and 8x4 dump trucks have relatively short wheelbases, while other models are compatible. Regarding 6x4 tractor trucks, the wheelbase of traditional gasoline trucks is 3300mm, which is ideal, but currently cannot accommodate a large battery capacity. For rear-mounted battery swap models, the wheelbase is currently extended to 3800mm, but this space cannot accommodate the target battery capacity. Currently, we are promoting clients to extend the wheelbase to 4200mm, and then break down the battery space based on this wheelbase. Regarding 8x4 dump trucks, there are both urban and mining applications. For mining applications, the longer wheelbase of 8x4 dump trucks ensures transport capacity, and the increased wheelbase allows for the required battery capacity. The wheelbase of traditional fuel vehicles in urban 8*4 dump trucks is 2500~2600mm, and this space cannot accommodate the target power. For models with rear-mounted battery swapping, the wheelbase is extended to 3200~3300mm. Chassis battery swapping can be based on this extended wheelbase to decompose the battery space.

[0246] The space limiting factors at the front end of the battery include: leaf springs and their brackets. Considering heavy loads, the industry generally has a space of around 1600 to 1800 mm (900 mm on one side). The space limiting factors at the rear end of the battery include: fenders, which are about 700 mm away from the center of the wheel. A 50 mm safety gap is reserved at the front and rear ends of the battery. The envelope size of the battery swap system for a 6*4 tractor is approximately 4200-900-700-100 = 2500 mm (three packages), and the envelope size of the battery swap system for an 8*4 dump truck is approximately 3300-900-700-100 = 1600 mm (two packages). Based on the envelope space of the above two battery swap systems, considering the 20 to 30 mm gap between the battery swap systems, the length envelope size of each battery swap system is approximately 700 to 820 mm.

[0247] When designing the width envelope of the battery swap system, it is sufficient to consider not exceeding the vehicle width required by regulations. For example, the width of a heavy-duty electric truck is 2550mm.

[0248] When designing the height envelope size of the battery swap system, it is considered that a 20mm gap is maintained between the upper end of the battery swap system and the upper wing surface of the vehicle beam, and a ground clearance of 300mm or more or 400mm is maintained between the bottom of the battery swap system and the ground. The height of the upper wing 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.

[0249] Furthermore, in order to improve the compatibility and interchangeability of battery replacement, the present application also proposes some embodiments of the battery mounting bracket 10.

[0250] In some embodiments, referring to FIG. 15 , in the longitudinal direction of the vehicle (eg, the first direction X), the length of the battery mounting space 4 is Y1 and satisfies: 620 mm ≤ Y1 ≤ 720 mm.

[0251] In some embodiments, referring to FIG. 15 , in the width direction of the vehicle (eg, the second direction Y), the width of the battery mounting space 4 is N1 and satisfies: 690 mm ≤ N1 ≤ 815 mm.

[0252] In some embodiments, referring to FIG. 15 , in the width direction of the vehicle (eg, the second direction Y), the minimum width between the two second main body walls 12 (eg, the battery avoidance opening 14 ) is N2 , and satisfies: 660 mm ≤ N2 ≤ 680 mm.

[0253] In some embodiments, referring to Figure 16, in the width direction of the vehicle (such as the second direction Y), the total width of the battery mounting rack 10 is P, and in the length direction of the vehicle (such as the first direction X), the total length of the battery mounting rack 10 is R, and satisfies: 2300mm≤P≤2550mm, 700mm≤R≤900mm (for example, there is only one battery mounting space 4), or 1500mm≤R≤1700mm (for example, there are two battery mounting spaces 4), or 2300mm≤R≤2500mm (for example, there are three battery mounting spaces 4), or 3100mm≤R≤3300mm (for example, there are four battery mounting spaces 4).
