[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. When batteries are installed in vehicles, the space available for placement is limited, resulting in limited power consumption and impacting the vehicle's range between battery swaps.

[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, which can expand the battery mounting space to increase the vehicle's range after a single battery replacement.

[0007] In the first aspect, the present application provides a battery mounting bracket for mounting a battery to a vehicle beam. The battery mounting bracket includes: a main body and an extension portion. The main body is used to be connected to the vehicle beam and extends along the length direction of the vehicle beam. The extension portion forms an angle with the extension direction of the main body and extends in a direction away from the main body. A mounting structure is provided on the extension portion, and the mounting structure is used to mount the battery.

[0008] In the technical solution of the embodiment of the present application, since the length direction of the extension part forms an angle with the extension direction of the main part and extends in a direction away from the main part, and a mounting structure for mounting the battery is provided on the extension part, such a design can expand the battery mounting space in the width direction of the vehicle, which is beneficial to increase the size of the battery in the width direction of the vehicle, and is beneficial to flexibly set the distribution position, number and structural form of the mounting structure on the extension part, so as to improve the mounting strength of large-size batteries, thereby improving the vehicle's cruising range on a single battery replacement.

[0009] In some embodiments, the extension portions on at least one side in the width direction of the main body are configured as a plurality and are arranged at intervals along the extension direction of the main body, and a battery mounting space is defined between two adjacent extension portions.

[0010] The above technical solution makes full use of the space along the length of the vehicle to arrange more extensions, thereby defining a larger number of battery mounting spaces, thereby mounting a larger number of mounted batteries. This increases both the battery size and the number of mounted batteries, further improving the vehicle's range per battery swap. Furthermore, two adjacent extensions along the extension direction of the main body can serve as the outer walls of the battery mounting space, providing some protection for the batteries, thereby reducing damage to the batteries and improving the reliability of the batteries in providing power to the vehicle.

[0011] In some embodiments, a mounting structure is arranged on a side of the extension portion facing the battery mounting space.

[0012] In the above technical solution, by arranging the mounting structure on the side of the extension part facing the battery mounting space, it is helpful to reduce the difficulty of arranging the mounting structure, and there is sufficient space to flexibly set the structural form of the mounting structure, so that the mounting structure can mount the battery more easily and reliably.

[0013] 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 of the extension direction of the main body portion, and mounting structures are arranged on both sides of the battery mounting spaces facing both sides of the common extension portion.

[0014] In the above technical solution, when the number of battery mounting spaces arranged at intervals along the extension direction of the main body is fixed, the number of extensions arranged at intervals along the extension direction of the main body can be reduced, which is beneficial to reducing costs and reducing the load of the vehicle.

[0015] In some embodiments, the mounting structures on both sides of the common extension portion in the extension direction of the main body portion are misaligned in their orthographic projections on a projection plane perpendicular to the extension direction of the main body portion.

[0016] In the above technical solution, by setting the mounting structures on both sides of the common extension part to be misaligned in the projection on the projection plane perpendicular to the extension direction of the main body, 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 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.

[0017] In some embodiments, a mounting structure is provided on the extension portions on both sides of the battery mounting space in the extension direction of the main body.

[0018] In the above technical solution, the extension parts on both sides of the battery mounting space in the extension direction of the main body can play the role of supporting the batteries in the battery mounting space. The 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 common extension parts and improving the mounting reliability of the battery.

[0019] In some embodiments, the mounting structures on both sides of the battery mounting space in the extension direction of the main body are misaligned in their orthographic projections on a projection plane perpendicular to the extension direction of the main body.

[0020] In the above technical solution, by arranging the mounting structures on both sides of the battery mounting space so that their orthographic projections on a projection plane perpendicular to the extension direction of the main body are offset, this further helps disperse the force on the mounting structures on both sides, further alleviating stress concentration that can cause deformation and fracture of the extension. In addition, when the mounting structures on both sides of the common extension along the extension direction of the main body are offset in their orthographic projections on a projection plane perpendicular to the extension direction of the main body, and when the mounting structures on both sides of the battery mounting space along the extension direction of the main body are offset in their orthographic projections on a projection plane perpendicular to the extension direction of the main body, multiple extensions can be constructed with the same structure, thereby reducing costs and simplifying production processes.

[0021] In some embodiments, a plurality of mounting structures are provided on the side of the extension portion facing the battery mounting space, with at least two of the mounting structures spaced apart along the length of the extension portion. This technical solution facilitates full utilization of the space along the length of the extension portion, allowing for the placement of a greater number of mounting structures, thereby enhancing battery mounting stability or increasing the number of batteries that can be mounted within the battery mounting space.

[0022] In some embodiments, the extension portion includes a mounting edge that protrudes toward the battery mounting space, and the mounting structure is located on the mounting edge. In the above technical solution, the provision of the mounting edge helps to reduce the difficulty of installing the mounting structure, and it is easy to realize that the mounting structure is located on the side of the extension portion facing the battery mounting space. Moreover, the mounting edge can provide a certain direct or indirect support for the battery, thereby enhancing the battery mounting stability.

[0023] In some embodiments, the mounting edge is located at the lower edge of the extension portion in the height direction. In the above technical solution, the mounting structure is set at a lower height, which helps to reduce the difficulty of maintaining the mounting structure, facilitates the loading connection between the mounting structure and the battery, and improves the compactness of the battery and the extension portion, reducing space waste. The saved space can further increase the size of the battery, thereby further improving the battery's size energy density.

[0024] In some embodiments, the length direction of the mounting edge is the same as the extension direction of the extension portion, there are multiple mounting structures, and the mounting edge is provided with multiple mounting structures arranged at intervals along the length direction of the mounting edge.

[0025] In the above technical solution, since the length direction of the mounting edge is the same as the length direction of the extension part, it is beneficial to reduce the processing difficulty of the mounting edge, so that the mounting edge has a larger length dimension and a larger number of mounting structures are set. Multiple mounting structures are set along the length direction of the mounting edge, which is beneficial to enhance the mounting stability of the battery, or to increase the number of batteries mounted on the mounting edge.

[0026] In some embodiments, the length direction of the mounting edge is the same as the extension direction of the extension portion, and the mounting structure on the mounting edge is configured as one and extends along the length direction of the mounting edge.

[0027] In the above technical solution, by setting only one mounting structure on the mounting edge, it is helpful to reduce the processing difficulty of the mounting structure, and the mounting structure extends along the length direction of the mounting edge, that is, the length direction of the mounting structure is consistent with the length direction of the mounting edge, so that the length dimension of the mounting structure is larger, with a larger force-bearing area, or with more connection positions, so as to facilitate simultaneous connection with multiple connection structures on the battery, improve the mounting reliability of the battery, or facilitate simultaneous mounting of multiple batteries.

[0028] In some embodiments, an extension portion is disposed on one side of the main body portion in a width direction.

[0029] In the above technical solution, by arranging the extension part only on one side in the width direction of the main body, the force transmitted from the extension part on which the battery is mounted to the main body can be reduced, thereby improving the connection reliability between the extension part and the main body, and improving the connection reliability between the main body and the vehicle beam, thereby improving the mounting reliability of the battery.

[0030] In some embodiments, the extension portion is disposed on each of both sides in the width direction of the main body portion.

[0031] In the above technical solution, by arranging extension parts on both sides of the width direction of the main body, and only by connecting one main body to the vehicle beam, both sides of the vehicle beam can have extension parts, so that the extension parts on both sides can be used to mount batteries respectively. For example, the two parts of the same battery located on both sides of the width direction of the vehicle beam can be mounted respectively, or the two batteries located on both sides of the width direction of the vehicle beam can be mounted respectively, thereby increasing the mounting strength of the battery or increasing the number of mounted batteries.

[0032] In some embodiments, the extension portion includes a first extension portion and a second extension portion respectively arranged on both sides of the width direction of the main body portion, the extension directions of the first extension portion and the second extension portion are the same, and, projected along the extension direction of the first extension portion, the projections of the first extension portion and the second extension portion overlap.

[0033] In the above technical solution, by setting the extension directions of the first extension part and the first extension part to be the same, and the projections of the first extension part and the first extension part along the extension direction of the first extension part coincide with each other, the first extension part and the first extension part can simultaneously mount the two parts of the same battery located on both sides of the width direction of the vehicle beam. In this way, the size of the battery can be made larger to reduce the number of batteries and reduce the complexity of battery replacement.

[0034] In some embodiments, the battery mounting bracket further includes a reinforcing portion configured to connect at least two extending portions located on the same side in a width direction of the main body.

[0035] 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.

[0036] In some embodiments, the height of the extension portion decreases in a direction away from the main body.

[0037] In the above technical solution, the height of the extension portion is set to decrease in the direction away from the main body portion, so that the height of the area of ​​the extension portion away from the main body portion is smaller. That is, the height of the end portion of the extension portion connected to the main body portion is relatively large, while the height of the end portion of the extension portion away from the main body portion is relatively small, thereby enhancing the connection strength between the extension portion and the main body portion, 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.

[0038] In some embodiments, the mounting structure is located at the lower edge of the extension portion, the lower edge of the extension portion extends horizontally, and the upper edge of the extension portion decreases in a direction away from the main body portion. In the above technical solution, the mounting structures are advantageously located at the same level, thereby facilitating the battery mounting operation.

[0039] In some embodiments, reinforcing ribs are further provided on the extension portion.

[0040] In the above technical solution, reinforcing ribs are provided to enhance the structural strength of the extension portion and improve the deformation problem of the extension portion under stress.

[0041] In some embodiments, at least part of the reinforcing ribs are arranged near the middle of the extension portion in the length direction; or, at least part of the reinforcing ribs are arranged along the height direction of the extension portion corresponding to the mounting structure; or, when multiple mounting structures are provided on the extension portion, at least part of the reinforcing ribs are arranged between two adjacent mounting structures along the height direction of the extension portion.

[0042] In the above technical solution, by setting the positions of at least part of the reinforcing ribs, the structural strength of the extension portion can be better improved while reducing the number of reinforcing ribs, thereby improving the mounting reliability of the battery.

[0043] In some embodiments, a first weight-reducing structure is provided on the extension portion.

[0044] In the above technical solution, the first weight-reducing structure is provided to reduce the weight of the extension portion, thereby facilitating a lightweight design of the battery mounting rack.

[0045] In some embodiments, the main body includes a beam avoidance groove, and the beam avoidance groove has an opening that passes through along the extension direction of the main body.

[0046] In the above technical solution, a vehicle beam avoidance groove is provided, and the vehicle beam avoidance groove has an opening that passes through along the extension direction of the main body, so as to facilitate accommodating at least part of the vehicle beam through the vehicle beam avoidance groove, and the opening can avoid the vehicle beam, so as to facilitate avoiding interference between the battery mounting frame and the vehicle beam, thereby improving and reducing the difficulty of loading and unloading the battery mounting frame, improving the compactness of the cooperation between the main body and the vehicle beam, and making full use of the space near the vehicle beam to set the battery, which is conducive to increasing the size of the battery.

[0047] In some embodiments, the main body includes a first main body wall and two second main body walls, the first main body wall is arranged along the width direction of the main body, and the two second main body walls are arranged along the extension direction of the main body and are respectively connected to the two ends of the first main body wall along the width direction of the main body to form a beam avoidance groove with an open top.

[0048] In the above technical solution, the beam avoidance groove is defined by the first main body wall and two second main body walls, thereby reducing the difficulty of forming the beam avoidance groove. The two second main body walls are respectively connected to the widthwise ends of the first main body wall to define an opening extending through the length of the main body. Furthermore, because the top of the beam avoidance groove is open, the main body can be pushed upward from the bottom to allow the beam to enter the beam avoidance groove, thereby reducing the difficulty of assembling the battery mounting bracket onto the beam. The battery mounting bracket can be installed later on the already assembled beam, making the battery mounting bracket suitable for use with a variety of vehicle models.

[0049] In some embodiments, the extension portion is connected to the second main body wall.

[0050] In the above technical solution, the difficulty of connecting the extension part and the main body part can be reduced. Moreover, the second main body walls on both sides can be used to connect the extension part, so that the extension part can be located on both sides of the width direction of the vehicle beam, so that the batteries can be arranged in the width direction of the vehicle beam to increase the size of the battery or increase the number of batteries.

[0051] In some embodiments, a second weight-reducing structure is provided on the first main body wall and / or the second main body wall.

[0052] Therefore, a first weight-reducing structure can be set on the first main wall and / or a second weight-reducing structure can be set on the second main wall, which is beneficial to reducing the weight of the first main wall or the second main wall, and further beneficial to achieving a lightweight design of the battery mounting rack.

[0053] In some embodiments, at least one mounting structure is also provided on the first main body wall.

[0054] Therefore, by setting a mounting structure on the first main body wall, the installation space of the first main body wall 1 can be fully utilized to improve space utilization, and it is beneficial to increase the number of mounting points of the mounted batteries or increase the number of batteries 30 that can be mounted.

[0055] In some embodiments, the first main body wall and the two second main body walls are integrally formed. In this way, the first main body wall and the two second main body walls can be constructed as an integrally formed structure, which is beneficial to reducing production processes, thereby reducing production costs and improving structural reliability.

[0056] In some embodiments, the main body and the extension are integrally formed, so that the main body and the extension can be constructed as an integrally formed structure, which is conducive to reducing production processes, thereby reducing production costs and improving structural reliability.

[0057] In a second aspect, the present application provides a vehicle frame assembly, which includes a vehicle beam and a battery mounting bracket as described in any one of the above embodiments, wherein the battery mounting bracket is used to mount a battery to the vehicle beam.

[0060] In the technical solution of the embodiment of the present application, since the length direction of the extension part forms an angle with the length direction of the vehicle beam and extends in a direction away from the vehicle beam, and a mounting structure for mounting the battery is provided on the extension part, such a design can expand the battery mounting space in the width direction of the vehicle, which is beneficial to increase the size of the battery in the width direction of the vehicle, and is beneficial to flexibly set the distribution position, number and structural form of the mounting structure on the extension part, so as to improve the mounting strength of large-size batteries, thereby improving the vehicle's cruising range on a single battery replacement.

[0061] In some embodiments, the extension portions on at least one side in the width direction of the vehicle beam are configured as multiple and are spaced apart along the length direction of the vehicle beam, and a battery mounting space is defined between two adjacent extension portions.

[0062] The above technical solution makes full use of the space along the length of the vehicle to arrange more extensions, thereby defining more battery mounting spaces and accommodating more batteries. This increases both battery size and the number of batteries that can be mounted, further improving the vehicle's range per battery swap. Furthermore, two adjacent extensions along the length of the beam serve as the outer walls of the battery mounting spaces, providing some protection for the batteries, reducing damage and improving the reliability of the batteries in providing power to the vehicle.

[0076] 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.

[0077] In some embodiments, the mounting edge is located at a lower edge of the extension portion in the height direction of the vehicle beam.

[0099] In the above technical solution, the first weight-reducing structure is provided to reduce the weight of the extension portion, thereby facilitating a lightweight design of the battery mounting rack.

[0100] In some embodiments, the extension portion is entirely located on one side of the vehicle beam in the width direction, and the frame assembly further comprises: a main body portion connected to the vehicle beam, and the extension portion is connected to the main body portion.

[0101] In the above technical solution, the main body allows the extension to be connected to the beam via the main body, thus simplifying the installation of the extension. Furthermore, by locating the extension on one side of the beam in the width direction, the space along the beam width can be fully utilized to mount the battery, thereby facilitating an increase in battery size. Furthermore, when multiple extensions are provided, for example, they can be first installed on the main body before being connected to the beam.

[0106] In some embodiments, the battery includes an upper battery portion and a lower battery portion, the upper battery portion is higher than the bottom surface of the vehicle beam, and the lower battery portion is lower than the bottom surface of the vehicle beam.

[0107] In the above technical solution, the upper part of the battery can occupy the horizontal space on both sides of the width of the vehicle beam, thereby improving space utilization, so that the size of the battery in the height direction of the vehicle can be increased to improve the energy density of the battery.

[0108] In some embodiments, in the length direction of the vehicle beam, the size of the upper battery portion is smaller than that of the lower battery portion, so as to form a step surface between the upper battery portion and the lower battery portion, and the step surface stops at the bottom of the extension portion.

[0109] In the above technical solution, when the battery is actually installed from the bottom up, the bottom of the extension and the stop on the stepped surface can be used to indicate that the battery is properly installed, thereby preventing the battery from being excessively squeezed upward and hitting the bottom of the vehicle, thereby protecting the battery. In addition, setting the size of the lower battery larger than that of the upper battery can further increase the battery size to a certain extent, thereby further improving the battery's size and energy density.

[0110] In some embodiments, the battery includes two battery side portions and a battery central portion. In the width direction of the vehicle beam, 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 that passes through the length direction of the vehicle beam and is open at the top between the two battery side portions and the battery central portion.

[0111] In the above technical solution, the structure of the battery 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 size energy density of the battery.

[0112] 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.

[0138] In the description of the embodiments of this application, the technical terms "first" and "second" are used only to distinguish different objects and should not be understood to indicate or imply relative importance or implicitly specify the quantity, specific order, or primary and secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "plurality" is more than two, unless otherwise clearly and specifically defined.

[0139] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0140] In the description of the embodiments of this application, the term "and / or" is simply a description of the association relationship between related objects, indicating that three relationships can exist. For example, X and / or Y can represent the following three situations: X exists alone, X and Y exist simultaneously, and Y exists alone. In addition, the character " / " in this document generally indicates that the related objects are in an "or" relationship.

[0141] In the description of the embodiments of the present application, the term "multiple" refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0142] In the description of the embodiments of the present application, the technical terms "longitudinal", "transverse", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they should not be understood as limiting the embodiments of the present application.

[0143] In the description of the embodiments of the present application, unless otherwise expressly specified or limited, technical terms such as "installed," "connected," "connected," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integration; they can refer to direct connections or indirect connections through an intermediate medium; they can refer to internal communication between two components or interaction between two components. Those skilled in the art can understand the specific meanings of the above terms in the embodiments of the present application based on specific circumstances.

[0144] 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.

[0145] Some vehicles in the related art have a beam at the bottom of the vehicle, the length direction of the beam is consistent with the length direction of the vehicle, and mounting structures are respectively provided on the two side walls of the beam in the width direction of the vehicle. The power battery is arranged at the bottom of the vehicle and mounted on the mounting structure. However, the mounting structure arranged on the side wall of the beam occupies the space of the battery in the width direction of the vehicle, resulting in that the size of the battery in the width direction of the vehicle is difficult to increase, and the size energy density of the battery is difficult to improve; moreover, the side wall space of the beam is limited, resulting in the distribution position, number and structural form of the mounting structure being limited, making it difficult to meet the mounting strength requirements of large-size batteries, resulting in that the size energy density of the battery is difficult to improve, thereby affecting the cruising range of the whole vehicle on a single battery replacement.

[0146] In order to increase the size and energy density of the battery, the present application proposes a battery mounting bracket, wherein the battery mounting bracket includes a main body and an extension portion, the main body portion is used to be connected to the vehicle beam, the extension portion is at an angle to the length direction of the vehicle beam and extends in a direction away from the vehicle beam, for example, extension portions are respectively provided on both sides of the width of the vehicle beam and the extension portions extend along the width direction of the vehicle beam, and a mounting structure is provided on the extension portion, and the mounting structure is used to mount the battery.

[0147] When using such a battery mounting bracket to mount the battery on the vehicle beam, the extension of the mounting structure's extended portion forms an angle with the length of the beam, so the extension and the mounting structure thereon do not occupy space for the battery in the vehicle width direction, thereby increasing the battery's size in the vehicle width direction and improving the battery's size-energy density. Furthermore, since the extension of the extension forms an angle with the length of the beam, placing the mounting structure on the extension rather than on the beam increases the mounting space available for the mounting structure, facilitating flexible configuration of the mounting structure's distribution, number, and structural form, meeting the mounting strength requirements for large-sized batteries and facilitating the mounting of larger batteries, thereby increasing the vehicle's range per battery swap.

[0148] In short, in the context of increasing demand for battery layout space and vehicle range on a single battery swap, the battery mounting rack of the present application can expand the battery mounting space, which is conducive to increasing the size of the mounted battery, thereby improving the vehicle range on a single battery swap.

[0149] 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.

[0150] For the convenience of description, the following embodiments are described using a vehicle 1000 as an example of an embodiment of the present application.

[0151] 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.

[0152] 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 .

[0153] 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.

[0154] 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 cell 302 may be housed within the housing 301. Alternatively, the battery 30 may be constructed by first connecting multiple battery cells 302 in series, in parallel, or in a hybrid connection to form a battery module, which is then connected in series, in parallel, or in a hybrid connection to form a complete battery module, and then housed within the housing 301. The battery 30 may also include other structures, such as a busbar for electrically connecting the multiple battery cells 302.

[0155] 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.

[0156] 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.

[0157] 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.

[0158] 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.

[0159] 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.

[0160] As shown in Figure 1 , an embodiment of the present application provides a battery mounting bracket 10 for mounting a battery 30 to a vehicle beam 20 . As shown in Figures 3 and 4 , Figure 3 shows a schematic diagram of the connection between the battery mounting bracket 10, the vehicle beam 20, and the battery 30, while Figure 4 shows a schematic diagram of the connection between the battery mounting bracket 10 and the vehicle beam 20.

[0161] As shown in Figures 3 and 4, in some embodiments, the battery mounting bracket 10 includes a main body 1 and an extension 2. The main body 1 is used to connect to the vehicle beam 20 and extends along the length of the vehicle beam 20. The extension 2 has a length direction (e.g., the second direction Y) that forms an angle with the extension direction (e.g., the first direction X) of the main body 1 and extends in a direction away from the main body 1. The extension 2 is provided with a mounting structure 3 for mounting a battery 30.

[0162] 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.

[0163] The vehicle beam 20 is the longitudinal beam or underbody beam of the vehicle 1000. The longitudinal direction of the vehicle beam 20 coincides with the longitudinal direction of the vehicle 1000, i.e., the front-to-back direction of the vehicle. "Main body 1 extends along the longitudinal direction of the vehicle beam 20" means that the extension direction of the main body 1 (e.g., the first direction X) coincides with the longitudinal direction of the vehicle beam 20, i.e., the front-to-back direction of the vehicle 1000. Therefore, "the longitudinal direction of the extension portion 2 (e.g., the second direction Y) forms an angle with the extension direction of the main body 1 (e.g., the first direction X)" can be understood as meaning that the extension direction of the extension portion 2 intersects the longitudinal direction of the vehicle 1000, for example, at an acute angle, a right angle, or an obtuse angle.

[0164] In this way, the extension portion 2 and the battery 30 can be arranged along the length direction of the vehicle 1000. For example, the extension portion 2 can be located on the front and / or rear side of the battery 30. The extension portion 2 and the mounting structure 3 arranged on the extension portion 2 occupy the space other than the battery 30 in the length direction of the vehicle 1000, such as the space on the front and / or rear side of the battery 30, but will not occupy the space other than the battery 30 in the width direction of the vehicle 1000, such as the space on the left and right sides of the battery 30, which is beneficial to increase the size of the battery 30 in the width direction of the vehicle, such as increasing the size of the battery 30 in the left and right directions.

[0165] It can be understood that the length of vehicle 1000 is greater than the width of vehicle 1000. Vehicle 1000 has a larger accommodating space in the length direction, while the accommodating space in the width direction of vehicle 1000 is limited. By utilizing the relatively sufficient space on the front and rear sides of the battery 30 to set the extension part 2 and the mounting structure 3, the extension part 2 and the mounting structure 3 can be avoided from occupying the space on the left and right sides of the battery 30, so that the space saved in the left and right directions can be used to increase the size of the battery 30, thereby improving the size energy density of the battery 30.

[0166] Moreover, compared with the solution of setting the mounting structure on the two side walls of the vehicle beam, since the length direction of the extension part 2 (such as the second direction Y) of some embodiments of the present application forms an angle with the extension direction of the main body 1 (such as the first direction X), there is relatively sufficient space on the extension part 2 to set the mounting structure 3, so as to flexibly set the distribution position, number and structural form of the mounting structure 3 on the extension part 2, which is beneficial to improve the installation strength of the larger-sized battery 30 mounted on the mounting structure 3, and improve the mounting reliability of the battery 30, thereby helping to increase the vehicle's 1000 single battery replacement range.

[0167] The structure of the mounting structure 3 is not limited, for example, it may include but is not limited to a mounting groove, a mounting hole, a mounting protrusion, a mounting pin, a mounting screw, etc., which are not limited here.

[0168] In addition, it should be noted that the connection method between the main body 1 and the beam 20 is not limited. It can be directly connected to the part of the beam 20 itself facing the main body 1, or it can be indirectly connected to the exterior parts provided on the beam 20 facing the main body 1.

[0169] In addition, it should be noted that the connection position between the main body 1 and the vehicle beam 20 is not limited, and for example, it can be connected to at least one of the top, bottom, or side of the vehicle beam 20 .

[0170] In some embodiments, referring again to Figures 3 and 4 , a plurality of extensions 2 are provided on at least one side of the main body 1 in the width direction (e.g., the second direction Y) and are spaced apart along the extension direction (e.g., the first direction X) of the main body 1. A battery mounting space 4 is defined between two adjacent extensions 2 along the extension direction (e.g., the first direction X) of the main body 1. It is worth noting that the width direction (e.g., the second direction Y) of the main body 1 coincides with the width direction of the vehicle beam 20 (e.g., the direction Y shown in Figure 3 ), i.e., the left-right direction of the vehicle 1000.

[0171] That is, a plurality of extension portions 2 are provided on at least one side of the main body 1 in the width direction (e.g., the second direction Y), and the plurality of extension portions 2 located on the same side of the main body 1 in the width direction (e.g., the second direction Y) are spaced apart along the extension direction (e.g., the first direction X) of the main body 1. For example, a plurality of extension portions 2 spaced apart along the front-to-back direction may be provided on at least one of the left and right sides of the main body 1.

[0172] It can be understood that the mounting structure 3 on the extension portion 2 is used to mount the battery 30 in the battery mounting space 4, that is, when the battery 30 is connected to the mounting structure 3, at least part of the battery 30 can be accommodated in the battery mounting space 4, presenting a mounted state.

[0173] In the above technical solution, the two adjacent extension portions 2 along the extension direction of the main body 1 (such as the first direction X) can serve as the outer wall of the battery mounting space 4 to provide a certain degree of protection for the battery 30, thereby reducing damage to the battery 30 and improving the reliability of the battery 30 in providing electrical energy to the vehicle 1000.

[0174] In addition, since the extension portion 2 is configured as multiple and is arranged at intervals along the extension direction of the main body 1 (such as the first direction X), it is beneficial to make full use of the space in the length direction of the vehicle 1000 to arrange more extension portions 2, so as to define a larger number of battery mounting spaces 4, thereby mounting a larger number of mounted batteries 30, thereby increasing the size of the battery 30 while also increasing the number of mounted batteries 30, further improving the cruising range of the vehicle 1000 on a single battery replacement.

[0175] For example, please refer to Figures 3 and 4 again. Four extensions 2 are provided on one side of the width of the vehicle beam 20. The four extensions 2 are arranged at intervals along the extension direction of the main body 1 (such as the first direction X), and the four extensions 2 define three battery mounting spaces 4. Each battery mounting space 4 can mount at least one battery 30, and when the battery 30 is mounted on the mounting structure 3, at least part of the battery 30 is located in the battery mounting space 4. At this time, the two adjacent extensions 2 can serve as the outer wall of the battery mounting space 4 to protect the battery 30 to a certain extent, so as to reduce damage to the battery 30 and improve the reliability of the battery 30 in providing electrical energy to the vehicle 1000.

[0176] Of course, the number of extensions 2 in the above description is only for illustration. For example, the number of extensions 2 on the width side of the vehicle beam 20 may be three, five, or more, etc., which can be set according to the specific needs of the vehicle 1000.

[0177] When the battery mounting rack 10 includes multiple battery mounting spaces 4, the extension portion 2 between two battery mounting spaces 4 can be used to isolate the batteries 30 of two adjacent battery mounting spaces 4, thereby improving problems such as mutual collision and heat transfer between the batteries 30 of two adjacent battery mounting spaces 4. Of course, the battery mounting rack 10 can also include only one battery mounting space 4.

[0178] In some embodiments, the battery mounting space 4 extends through the height direction of the extension portion 2 (e.g., the third direction Z). "The battery mounting space 4 extends through the height direction of the extension portion 2" means that the battery mounting space 4 is open at both ends of the height direction of the extension portion 2 and is not obstructed by structures on the battery mounting bracket 10. The height direction of the extension portion 2 may be perpendicular to the thickness direction of the extension portion 2 (e.g., the first direction X) and the length direction of the extension portion 2 (the second direction Y).

[0179] For example, the height direction of the extension portion 2 can be set to be consistent with the height direction of the vehicle 1000. Therefore, when the battery 30 is mounted in the battery mounting space 4, the battery 30 can be free from the battery mounting frame 10 on both sides of the battery 30 in the height direction of the vehicle 1000. For example, the extension portion 2, the main body 1, and the mounting structure 3 do not occupy the space of the battery 30 in the height direction of the vehicle 1000, thereby improving the space utilization rate of the battery 30 in the height direction of the vehicle 1000, which is conducive to increasing the size of the battery 30 in the height direction of the vehicle 1000 and the size energy density of the battery 30, thereby increasing the cruising range of the vehicle 1000 after a single battery replacement, and ensuring the height of the battery 30 from the ground, ensuring the passability of the vehicle 1000. In addition, it is also beneficial to dissipate heat from the battery 30. In addition, it is also beneficial to reduce the weight of the battery mounting frame 10 and reduce the on-vehicle burden of the battery mounting frame 10.

[0180] 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.

[0181] In an embodiment of the present application, a battery mounting rack 10 includes a plurality of battery mounting spaces 4 sequentially arranged along an extension direction of the main body 1 (e.g., a first direction X). The battery mounting rack 10 is provided with a mounting structure 3 corresponding to each battery mounting space 4, so that each battery mounting space 4 can be used to mount a battery 30. The mounting structures 3 corresponding to different battery mounting spaces 4 can be independent of each other, so that the mounted battery 30 in each battery mounting space 4 can be individually replaced. The "correspondence" in the arrangement of the mounting structure 3 corresponding to the battery mounting space 4 refers to a correspondence in the relationship between the two, including but not limited to a correspondence in position.

[0182] But it is 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 each other along the second direction Y are used to mount the same battery 30, the 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 mounting structure 3 is conducive to improving the battery replacement efficiency.

[0183] 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.

[0184] 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 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 to 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.

[0185] In some embodiments, referring to Figures 4-6, Figure 5 is a partial enlarged view of section A in Figure 4, and Figure 6 is an orthographic projection view of the connection between the battery mounting bracket 10 and the vehicle beam 20 shown in Figure 4. The mounting structure 3 is arranged on the side of the extension portion 2 facing the battery mounting space 4. That is, the extension portion 2 includes a mounting surface 23 facing the battery mounting space 4, and the mounting structure 3 is arranged on the side of the mounting surface 23 facing the battery mounting space 4.

[0186] In this way, the mounting structure 3 corresponds to the battery mounting space 4 that it faces, and the battery 30 is mounted in the battery mounting space 4 that the mounting structure 3 faces. This clarifies the correspondence between the 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 mounting structure 3 facing the battery mounting space 4, thereby conveniently mounting the battery 30. Furthermore, when there are multiple battery mounting spaces 4, the mounting structures 3 corresponding to different battery mounting spaces 4 are positioned differently and do not interfere with each other. This allows the mounting structure 3 corresponding to each battery mounting space 4 to have sufficient space for flexible placement, making it easier and more reliable for the mounting structure 3 to mount the battery 30. Thus, by arranging the mounting structure 3 on the side of the extension portion 2 facing the battery mounting space 4, the difficulty of arranging the mounting structure 3 is reduced, and sufficient space for flexible placement of the mounting structure 3 is provided, making it easier and more reliable for the mounting structure 3 to mount the battery 30.

[0187] In some embodiments, please refer to Figures 4 to 6 again. At least one extension portion 2 located in the middle of the multiple extension portions 2 is a common extension portion 2a. The common extension portion 2a has battery mounting spaces 4 on both sides of the extension direction of the main body 1 (such as the first direction X), and mounting structures 3 are arranged on both sides of the battery mounting spaces 4 facing both sides of the common extension portion 2a.

[0188] It is worth noting that "at least one central extension portion 2 among the plurality of extension portions 2" refers to the remaining at least one extension portion 2 among the plurality of extension portions 2 arranged along the extension direction (e.g., the first direction X) of the main body 1, excluding the two extension portions 2 on either side. For example, when four extension portions 2 are provided on one width side of the beam 20, at least one of the two central extension portions 2 is a common extension portion 2a. The common extension portion 2a has two mounting surfaces 23 facing the battery mounting spaces 4 on either side.

[0189] Therefore, when the number of battery mounting spaces 4 arranged at intervals along the extension direction of the main body 1 (such as the first direction X) is fixed, the number of extension portions 2 arranged at intervals along the extension direction of the main body 1 (such as the first direction X) can be reduced. For example, in the minimum case, the number of extension portions 2 on a single side of the width of the vehicle beam 20 can be one more than the number of battery mounting spaces 4, that is, only one extension portion 2 is arranged between two adjacent battery mounting spaces 4 along the extension direction of the main body 1 (such as the first direction X), which is beneficial to reduce costs and reduce the load of the vehicle 1000.

[0190] However, the present application is not limited to this. For example, two extension portions 2 may be arranged between two adjacent battery mounting spaces 4 along the extension direction of the main body 1 (such as 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 mounting structure 3, thereby reducing the bearing force of each extension portion 2 on the battery and improving the mounting reliability of the battery 30.

[0191] In some embodiments, referring again to Figures 4-6 , the mounting structures 3 on both sides of the common extension portion 2a in the extension direction (e.g., first direction X) of the main body 1 are misaligned in their orthographic projections on a projection plane perpendicular to the extension direction (e.g., first direction X) of the main body 1. That is, the mounting structures 3 on the two mounting surfaces 23 of the common extension portion 2a are misaligned in their orthographic projections along the extension direction (e.g., first direction X) of the main body 1. For example, the distance from any mounting structure 3 on one side of the common extension portion 2a to the main body 1 in the longitudinal direction (e.g., second direction Y) of the extension portion 2 is different from the distance from any mounting structure 3 on the other side of the common extension portion 2a to the main body 1 in the longitudinal direction (e.g., second direction Y) of the extension portion 2.

[0192] Therefore, by setting the 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 extension direction of the main body 1 (such as 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 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 extension part 2, thereby improving the service life of the common extension part 2a and enhancing the mounting reliability of the battery 30.

[0193] In some embodiments, referring again to Figures 4 to 6 , the battery mounting space 4 is provided with mounting structures 3 on the extension portions 2 on both sides of the main body 1 in the extension direction (e.g., the first direction X). For example, the mounting surface 23 includes a first mounting surface 231 and a second mounting surface 232. The first mounting surface 231 and the second mounting surface 232 are respectively one side surface of two adjacent extension portions 2 facing the same battery mounting space 4. The first mounting surface 231 is provided with a mounting structure 3 on the side facing the battery mounting space 4, and the second mounting surface 232 is also provided with a mounting structure 3 on the side facing the battery mounting space 4. The battery 30 in the battery mounting space 4 is connected to the two mounting structures 3 respectively.

[0194] Therefore, the extension parts 2 on both sides of the battery mounting space 4 in the extension direction of the main body 1 (such as the first direction X) can play the role of supporting the battery 30 in the battery mounting space 4, and the mounting structures 3 on both sides can disperse the force to reduce stress concentration and cause deformation, fracture and other problems in the extension part 2, thereby improving the service life of the common extension part 2a, thereby improving the mounting reliability of the battery 30.

[0195] Furthermore, in some embodiments, the mounting structures 3 on both sides of the battery mounting space 4 in the extension direction (e.g., the first direction X) of the main body 1 are misaligned in their orthographic projections on a projection plane perpendicular to the extension direction (e.g., the first direction X) of the main body 1. For example, the distance from any mounting structure 3 on one side of the battery mounting space 4 to the main body 1 in the length direction (e.g., the second direction Y) of the extension portion 2 is different from the distance from any mounting structure 3 on the other side of the battery mounting space 4 to the main body 1 in the length direction (e.g., the second direction Y) of the extension portion 2.

[0196] Therefore, by setting the 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 extension direction of the main body 1 (such as the first direction X), it is further beneficial to disperse the force on the mounting structures 3 on both sides, and further improve the problems of deformation, fracture, etc. of the extension part 2 caused by stress concentration.

[0197] In addition, when the mounting structures 3 on both sides of the common extension portion 2a in the extension direction of the main body 1 (such as the first direction X) are misaligned in their orthographic projections on the projection plane perpendicular to the extension direction of the main body 1 (such as the first direction X), and the mounting structures 3 on both sides of the battery mounting space 4 in the extension direction of the main body 1 (such as the first direction X) are misaligned in their orthographic projections on the projection plane perpendicular to the extension direction of the main body 1 (such as the first direction X), multiple extension portions 2 can be constructed with the same structure, which is conducive to reducing costs and reducing production processes.

[0198] Of course, the present application is not limited to this. For example, the mounting structures 3 on both sides of the common extension portion 2a in the extension direction of the main body 1 (such as the first direction X) can also be set so that the orthographic projections on the projection plane perpendicular to the extension direction of the main body 1 (such as the first direction X) coincide. At this time, the orthographic projections of the mounting structures 3 on both sides of the battery mounting space 4 in the extension direction of the main body 1 (such as the first direction X) on the projection plane perpendicular to the extension direction of the main body 1 (such as the first direction X) can also coincide, thereby simplifying processing and reducing costs.

[0199] In some embodiments, referring to FIG. 4 and FIG. 5 , a plurality of mounting structures 3 are provided on one side of the extension portion 2 facing the battery mounting space 4 , and at least two of the mounting structures 3 are spaced apart along the length direction of the extension portion 2 (eg, the second direction Y).

[0200] In this way, it is beneficial to make full use of the space in the length direction of the extension part 2 (such as the second direction Y) and arrange more mounting structures 3, thereby enhancing the mounting stability of the battery 30, or increasing the number of batteries 30 mounted in the battery mounting space 4.

[0201] In some embodiments, referring to FIG5 , the extension portion 2 includes a mounting edge 24 that protrudes toward the battery mounting space 4, and the mounting structure 3 is located on the mounting edge 24. For example, the mounting edge 24 protrudes toward the interior of the battery mounting space 4 along the extension direction of the main body 1 (e.g., the first direction X).

[0202] In this way, by setting the mounting edge 24, it is helpful to reduce the difficulty of setting the mounting structure 3, and it is easy to realize that the mounting structure 3 is located on the side of the extension part 2 facing the battery mounting space 4. Moreover, the mounting edge 24 can play a certain direct or indirect supporting role on the battery 30 to enhance the mounting stability of the battery 30.

[0203] In some embodiments, referring to Figures 4 and 5 , the mounting edge 24 is located at the lower edge of the extension portion 2 in the height direction (e.g., the third direction Z). Here, the ends of the extension portion 2 in the height direction (e.g., the third direction Z) are defined as the upper and lower ends. When the height direction 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 are also the upper and lower ends in the direction of gravity.

[0204] As a result, the mounting structure 3 is set at a lower height, which is conducive to reducing the difficulty of maintaining the mounting structure 3, and is conducive to the loading connection between the mounting structure 3 and the battery 30, and improves the compactness of the fit between the battery 30 and the extension part 2, reduces space waste, and utilizes the saved space to further increase the size of the battery 30, thereby further improving the size energy density of the battery 30.

[0205] For example, when a tool is used to extend upward to the position of the mounting structure 3 to perform the mounting connection between the mounting structure 3 and the battery 30, the raised position of the tool is lower than the extension part 2, so that the lifting height of the tool can be reduced, and the tool does not need to be extended between the battery 30 and the extension part 2. There is no need to increase the gap between the battery 30 and the extension part 2 to meet the tool's insertion requirements, thereby reducing space waste and utilizing the saved space to further increase the size of the battery 30, thereby further improving the size energy density of the battery 30.

[0206] In some embodiments, please refer to Figures 4 and 5, the length direction of the mounting edge 24 is the same as the length direction of the extension portion 2 (such as the second direction Y), and a plurality of mounting structures 3 are provided on the mounting edge 24 and arranged at intervals along the length direction of the mounting edge 24.

[0207] Therefore, since the length direction of the mounting edge 24 is the same as the length direction of the extension part 2 (such as the second direction Y), it is beneficial to reduce the processing difficulty of the mounting edge 24, so that the mounting edge 24 has a larger length dimension and a larger number of mounting structures 3 are set. Multiple mounting structures 3 are set along the length direction of the mounting edge 24, which is beneficial to enhance the mounting stability of the battery 30, or to increase the number of batteries 30 mounted on the mounting edge 24.

[0208] In some embodiments, please refer to Figure 7, which is a partially enlarged view of a battery mounting rack 10 of another embodiment of the present application. The length direction of the mounting edge 24 is the same as the length direction of the extension portion 2 (such as the second direction Y), and the mounting structure 3 on the mounting edge 24 is configured as one and extends along the length direction of the mounting edge 24.

[0209] Therefore, by only setting one mounting structure 3 on the mounting edge 24, it is helpful to reduce the processing difficulty of the mounting structure 3, and the mounting structure 3 extends along the length direction of the mounting edge 24, that is, the length direction of the mounting structure 3 is consistent with the length direction of the mounting edge 24, so that the mounting structure 3 is larger in size, has a larger force-bearing area, or has more connection positions, so as to facilitate simultaneous connection with multiple connection structures on the battery 30, improve the mounting reliability of the battery 30, or facilitate simultaneous mounting of multiple batteries 30.

[0210] In some embodiments, an extension portion 2 is disposed on one side of the main body 1 in the width direction (e.g., the second direction Y). It is worth noting that the width direction (e.g., the second direction Y) of the main body 1 coincides with the width direction of the vehicle beam 20, and the width direction of the vehicle beam 20 coincides with the width direction of the vehicle 1000, e.g., the left-right direction of the vehicle 1000. For example, the extension portion 2 may be disposed on the left side of the main body 1, or on the right side of the main body 1.

[0211] Therefore, by arranging the extension portion 2 only on one side of the main body 1 in the width direction (such as the second direction Y), the force transmitted from the extension portion 2 on which the battery 30 is mounted to the main body 1 can be reduced, thereby improving the connection reliability between the extension portion 2 and the main body 1, and improving the connection reliability between the main body 1 and the vehicle beam 20, thereby improving the mounting reliability of the battery 30.

[0212] It is worth noting that if an extension portion 2 is arranged on one side of the main body 1 in the width direction (such as the second direction Y), and it is also desired that an extension portion 2 is provided on both sides of the width direction of the vehicle beam 20, at least two main bodies 1 can be installed on the vehicle beam 20, wherein an extension portion 2 is arranged on the left side of one main body 1 and an extension portion 2 is arranged on the right side of the other main body 1, so that both the left and right sides of the vehicle beam 20 can have an extension portion 2.

[0213] In some embodiments, referring to Figures 3 and 4 , an extension portion 2 is disposed on each of two sides of the main body 1 in the width direction (e.g., the second direction Y). In other words, multiple extension portions 2 are provided on the main body 1, with at least two of the multiple extension portions 2 located on either side of the main body 1 in the width direction (e.g., the second direction Y). It is worth noting that the width direction (e.g., the second direction Y) of the main body 1 coincides with the width direction of the vehicle beam 20, and the width direction of the vehicle beam 20 coincides with the width direction of the vehicle 1000, i.e., the left-right direction of the vehicle 1000. For example, an extension portion 2 is disposed on the left side of the main body 1, and an extension portion 2 is also disposed on the right side of the main body 1.

[0214] Therefore, by providing extension portions 2 on both sides of the main body 1 in the width direction (such as the second direction Y), and only by connecting one main body 1 to the vehicle beam 20, it is possible to have extension portions 2 on both sides of the vehicle beam 20, so that the extension portions 2 on both sides of the main body 1 can be used to mount the batteries 30 respectively. For example, the two parts of the same battery 30 located on both sides of the width direction of the vehicle beam 20 can be mounted respectively, or the two batteries 30 located on both sides of the width direction of the vehicle beam 20 can be mounted respectively, thereby increasing the mounting strength of the battery 30 or increasing the number of mounted batteries 30.

[0215] In some embodiments, please refer to Figures 3 and 4, the extension portion 2 includes a first extension portion 21 and a second extension portion 22 respectively arranged on both sides of the width direction (such as the second direction Y) of the main body 1, and the extension directions of the first extension portion 21 and the second extension portion 22 are the same, and, when projected along the extension direction of the first extension portion 21, the projections of the first extension portion 21 and the second extension portion 22 overlap.

[0216] It is worth noting that the width direction of the main body 1 (e.g., the second direction Y) is consistent with the width direction of the vehicle beam 20, such as the left-right direction of the vehicle 1000. For example, the first extension portion 21 and the second extension portion 22 both extend along the width direction of the vehicle beam 20, or the first extension portion 21 and the second extension portion 22 both extend in a direction oblique to the width direction of the vehicle beam 20, and the inclination angles are the same.

[0217] Therefore, by setting the extension directions of the first extension part 21 and the second extension part 22 to be the same, and the projections of the first extension part 21 and the second extension part 22 along the extension direction of the first extension part 21 overlap, the first extension part 21 and the second extension part 22 can simultaneously mount the two parts of the same battery 30 located on both sides of the width direction of the vehicle beam 20. In this way, the size of the battery 30 can be made larger to reduce the number of batteries 30 and reduce the complexity of battery replacement.

[0218] In some embodiments, referring to Figures 3 and 4, when a plurality of extensions 2 spaced apart along the extension direction (e.g., first direction X) of the main body 1 are provided on at least one side in the width direction (e.g., second direction Y) of the main body 1, the battery mounting rack 10 further comprises a reinforcing portion 5, which is used to connect at least two extensions 2 located on the same side in the width direction (e.g., second direction Y) of the main body 1. It is worth noting that this embodiment is applicable to both the cases where "at least one extension 2 is arranged on each of the two sides in the width direction of the main body 1" and "an extension 2 is arranged on one side in the width direction of the main body 1." In addition, the at least two extensions 2 connected by the reinforcing portion 5 may be adjacent or non-adjacent.

[0219] In addition, it is worth noting that the width direction of the main body 1 (e.g., the second direction Y) is consistent with the width direction of the vehicle beam 20, such as the left-right direction of the vehicle 1000. For example, at least two extensions 2 on the left side of the main body 1 are connected by the reinforcement 5, and / or at least two extensions 2 on the right side of the main body 1 are connected by the reinforcement 5.

[0220] 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 .

[0221] In some embodiments, the reinforcement portion 5 and the main body 1 are positioned on either side of the extension portion 2 in the longitudinal direction (e.g., the second direction Y). This allows the two extension portions 2 defining the battery mounting space 4 to be connected at both ends in the longitudinal direction (e.g., the second direction Y) of the extension portion 2, respectively, via the main body 1 and the reinforcement portion 5. This creates a ring-shaped structure around the battery mounting space 4, providing greater structural strength, improved mounting reliability for the battery 30, and more comprehensive circumferential protection for the battery 30. Furthermore, the location of the mounting structure 3 can be flexibly selected.

[0222] In some embodiments, referring to FIG5 , the height of the extension portion 2 (i.e., the dimension of the extension portion 2 in the height direction (e.g., the third direction Z)) decreases as it moves away from the main body portion 1. It is worth noting that "decreasing" can mean a gradual decrease or a stepwise decrease.

[0223] Therefore, by setting the height of the extension part 2 to tend to decrease in the direction away from the main body part 1, the height of the area of ​​the extension part 2 away from the main body part 1 is smaller, that is, the height of the end of the extension part 2 connected to the main body part 1 is relatively large, and the height of the end of the extension part 2 away from the main body part 1 is relatively small, thereby enhancing the connection strength between the extension part 2 and the main body part 1, improving the reliability of the extension part 2 for mounting the battery 30, and reducing the weight of the extension part 2, thereby reducing the load of the vehicle 1000.

[0224] When the mounting structure 3 is located at the lower edge of the extension portion 2, for example, on the mounting edge 24, and the mounting edge 24 is located at the lower edge of the extension portion 2, the lower edge of the extension portion 2 can be configured to extend horizontally, while the upper edge of the extension portion 2 decreases in a direction away from the main body portion 1. It is worth noting that the "decreasing trend" can be a gradual decrease or a step-by-step decrease. This helps to keep the mounting structures 3 at the same level, thereby facilitating the mounting operation of the battery 30.

[0225] In some embodiments, as shown in FIG7 , the extension portion 2 is further provided with reinforcing ribs 25. The structural form of the reinforcing ribs 25 is not limited and can be, for example, linear, curved, or cross-shaped. Thus, the provision of the reinforcing ribs 25 helps to enhance the structural strength of the extension portion 2 and improve the deformation problem of the extension portion 2 under stress.

[0226] For example, under normal circumstances, the farther the extension portion 2 is from the main body portion 1, the easier it is to deform. At least part of the reinforcing ribs 25 can be arranged close to the middle of the extension portion 2 in the length direction (such as the second direction Y), that is, in the center or approximately the center as a whole, for example, in the position range between 1 / 3-2 / 3 in the length direction of the extension portion 2. This can better improve the structural strength of the extension portion 2 while reducing the number of reinforcing ribs 25, and improve the reliability of the extension portion 2 for mounting the battery 30.

[0227] For example, when a battery 30 is mounted on the mounting structure 3 of the extension part 2, the position of the mounting structure 3 of the extension part 2 is subjected to concentrated force and is prone to deformation and damage. Therefore, at least part of the reinforcing ribs 25 can be arranged along the height direction of the extension part 2 (such as the third direction Z) corresponding to the mounting structure 3, thereby reducing the number of reinforcing ribs 25 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.

[0228] For example, when the extension portion 2 is provided with multiple mounting structures 3, at least some of the reinforcing ribs 25 are arranged between two adjacent mounting structures 3 along the height direction of the extension portion 2 (e.g., the third direction Z). When a battery 30 is mounted on the mounting structure 3 of the extension portion 2, the mounting structure 3 of the extension portion 2 is subjected to concentrated stress, making it susceptible to deformation and damage. By arranging at least some of the reinforcing ribs 25 between two adjacent mounting structures 3, the structural strength of the extension portion 2 between the two adjacent mounting structures 3 can be enhanced, the problem of stress concentration and fracture between the two adjacent mounting structures 3 can be improved, and the reliability of the extension portion 2 for mounting the battery 30 can be improved.

[0229] In some embodiments, referring to Figure 5, a first weight-reducing structure 26 is provided on the extension portion 2. For example, the first weight-reducing structure 26 may include but is not limited to a weight-reducing hole, a weight-reducing groove, or a thinning treatment.

[0230] In this way, by providing the first weight-reducing structure 26 , the weight of the extension portion 2 can be reduced, thereby facilitating a lightweight design of the battery mounting rack 10 .

[0231] In some embodiments, referring to FIG. 4 , the main body 1 includes a beam avoidance groove 13 , and the beam avoidance groove 13 has an opening that passes through the main body 1 along an extension direction (eg, a first direction X).

[0232] Therefore, by providing the vehicle beam avoidance groove 13, and the vehicle beam avoidance groove 13 has an opening that passes through along the extension direction of the main body 1 (such as the first direction X), it is convenient to accommodate at least part of the vehicle beam 20 through the vehicle beam avoidance groove 13, and the opening can avoid the vehicle beam 20, so as to avoid interference between the battery mounting frame 10 and the vehicle beam 20, thereby reducing the difficulty of loading and unloading the battery mounting frame 10, improving the compactness of the cooperation between the main body 1 and the vehicle beam 20, and making full use of the space near the vehicle beam 20 to set the battery 30, which is conducive to increasing the size of the battery 30.

[0233] 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, it may include two longitudinal beams 201 extending along the length direction of the vehicle 1000 (such as the first direction X) and at least one cross beam 202 extending along the width direction of the vehicle 1000 (such as the second direction Y). 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.

[0234] In some embodiments, please refer to Figure 4, the main body 1 includes a first main body wall 11 and two second main body walls 12, the first main body wall 11 is arranged along the width direction of the main body 1 (such as the second direction Y), and the two second main body walls 12 are arranged along the extension direction of the main body 1 (such as the first direction X), and the two second main body walls 12 are respectively connected to the two ends of the first main body wall 11 along the width direction of the main body 1 (such as the second direction Y) to form a top-open vehicle beam avoidance groove 13 between the first main body wall 11 and the two second main body walls 12.

[0235] It is worth noting that the width direction of the main body 1 (e.g., the second direction Y) coincides with the width direction of the vehicle beam 20, i.e., the left-right direction of the vehicle 1000. The phrase "the first main body wall 11 is arranged along the width direction of the main body 1 (e.g., the second direction Y)" means that the length direction of the first main body wall 11 coincides with the width direction of the main body 1 (e.g., the second direction Y). The phrase "the second main body walls 12 are all arranged along the extension direction of the main body 1 (e.g., the first direction X)" means that the length direction of the second main body wall 12 coincides with the extension direction of the main body 1 (e.g., the first direction X).

[0236] Thus, the beam avoidance groove 13 can be defined by the first main body wall 11 and the two second main body walls 12, thereby reducing the difficulty of forming the beam avoidance groove 13. The two second main body walls 12 are respectively connected to the ends of the first main body wall 11 along the width direction, thereby defining an opening that extends through the length of the main body 1. Furthermore, because the top of the beam avoidance groove 13 is open, 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 onto the beam 20. The battery mounting bracket 10 can be subsequently installed on the already assembled beam 20, 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 be configured to be open at the bottom. In this case, the battery mounting bracket 10 and the beam 20 can be assembled simultaneously during the assembly of the beam 20.

[0237] For example, in combination with Figure 4, the first main body wall 11 can be connected between the lower ends of the two second main body walls 12, so that the vehicle beam avoidance groove 13 is located above the first main body wall 11, so that the height dimension of the vehicle beam avoidance groove 13 with an open top is larger, and the vehicle beam 20 can be accommodated to a greater extent, thereby improving the compactness of the fit between the main body 1 and the vehicle beam 20 and reducing space waste.

[0238] For example, at least one of the first main body wall 11 and the second main body wall 12 may be fixedly connected to the vehicle beam 20 by fasteners such as screws, thereby meeting the requirement of installing the main body 1 on the vehicle beam 20 .

[0239] In some embodiments, referring to FIG5 , the extension 2 is connected to the second main body wall 12 . This simplifies the connection between the extension 2 and the main body 1 . Furthermore, the second main body walls 12 on both sides can be used to connect the extension 2 , allowing the extension 2 to be located on both sides of the beam 20 in the width direction. This allows the batteries 30 to be arranged in the width direction of the beam 20 , thereby increasing the size of the batteries 30 or the number of batteries 30 .

[0240] 8 , a second weight-reducing structure 14 is provided on the first main body wall 11 and / or the second main body wall 12. For example, the second weight-reducing structure 14 may include but is not limited to weight-reducing holes, weight-reducing grooves, or thinning treatments.

[0241] Therefore, a second weight-reducing structure 14 can be set on the first main wall 11 and / or a second weight-reducing structure 14 can be set on the second main wall 12, which is beneficial to reducing the weight of the first main wall 11 and / or the second main wall 12, and further beneficial to achieving a lightweight design of the battery mounting rack 10.

[0242] In some embodiments, referring to FIG8 , at least one mounting structure 3 is also provided on the first main body wall 11. It is worth noting that the battery 30 can be mounted only on the mounting structure 3 on the extension portion 2, only on the mounting structure 3 on the first main body wall 11, or simultaneously on the mounting structure 3 on the extension portion 2 and the mounting structure 3 on the first main body wall 11.

[0243] Therefore, by setting the mounting structure 3 on the first main body wall 11, the installation space at the first main body wall 11 can be fully utilized to improve space utilization, and it is beneficial to increase the number of mounting points of the mounted batteries 30 or increase the number of batteries 30 that can be mounted.

[0244] In some embodiments, the first main body wall 11 and the two second main body walls 12 are integrally formed. This allows the first main body wall 11 and the two second main body walls 12 to be constructed as an integrally formed structure, thereby reducing production steps and thereby lowering production costs. Of course, this is not limiting; the first main body wall 11 and the second main body wall 12 can also be configured as separate structures that are assembled and connected to improve structural reliability.

[0245] In some embodiments, the main body 1 and the extension 2 are integrally formed. This allows the main body 1 and the extension 2 to be constructed as a one-piece structure, thereby reducing production steps and thereby lowering production costs. Of course, this is not limiting; the main body 1 and the extension 2 can also be configured as separate structures that are assembled and connected, thereby improving structural reliability.

[0246] In a second aspect, referring to FIG. 4 , the present application provides a vehicle frame assembly 100 , which includes a vehicle beam 20 and a battery mounting bracket 10 as described in any of the above embodiments, wherein the battery mounting bracket 10 is used to mount a battery 30 to the vehicle beam 20 .

[0247] Therefore, when the battery 30 is installed on the vehicle beam 20 through the battery mounting rack 10, the mounting space of the battery 30 can be expanded, so as to facilitate mounting a larger battery 30 on the battery mounting rack 10, thereby increasing the cruising range of the vehicle 1000 after a single battery replacement.

[0248] In a third aspect, the present application provides another embodiment of a vehicle frame assembly, comprising: a vehicle beam 20 and an extension portion 2. It is worth noting that, compared to the vehicle frame assembly 100 of the second embodiment, the vehicle frame assembly of the third embodiment of the present application may not include a main body portion 1 for connecting to the vehicle beam 20, or may include a main body portion 1 for connecting to the vehicle beam 20. However, the shape of the main body portion 1 is not limited. For example, the main body portion 1 may extend along the length direction (e.g., the first direction X) of the vehicle beam 20, or may not extend along the length direction (e.g., the first direction X) of the vehicle beam 20. The shape of the main body portion 1 can be flexibly designed according to actual needs.

[0249] In some embodiments, as shown in Figures 3 and 4, at least a portion of the extension portion 2 is located on one side of the vehicle beam 20 in the width direction (such as the second direction Y), the portion of the extension portion 2 located on the side in the width direction (such as the second direction Y) of the vehicle beam 20 forms an angle with the length direction (such as the first direction X) of the vehicle beam 20 and extends in a direction away from the vehicle beam 20, and a mounting structure 3 is provided on the portion of the extension portion 2 located on the side in the width direction (such as the second direction Y) of the vehicle beam 20, and the mounting structure 3 is used to mount a battery 30.

[0250] Among them, the vehicle beam 20 is the longitudinal beam of the vehicle 1000 or the vehicle bottom beam, and the length direction of the vehicle beam 20 (such as the first direction X) is consistent with the length direction of the vehicle 1000, that is, the front and rear direction of the vehicle; therefore, "the part of the extension part 2 located on one side of the width direction (such as the second direction Y) of the vehicle beam 20 forms an angle with the length direction (such as the first direction X) of the vehicle beam 20" can be understood as: the extension direction of the part of the extension part 2 located on one side of the width direction (such as the second direction Y) of the vehicle beam 20 intersects with the length direction of the vehicle 1000, for example, it can be an acute angle, a right angle or an obtuse angle.

[0251] In this way, the extension portion 2 and the battery 30 can be arranged along the length direction of the vehicle 1000. For example, the extension portion 2 can be located on the front and / or rear side of the battery 30. The extension portion 2 and the mounting structure 3 arranged on the extension portion 2 occupy the space other than the battery 30 in the length direction of the vehicle 1000, such as the space on the front and / or rear side of the battery 30, but will not occupy the space other than the battery 30 in the width direction of the vehicle 1000, such as the space on the left and right sides of the battery 30, which is beneficial to increase the size of the battery 30 in the width direction of the vehicle, such as increasing the size of the battery 30 in the left and right directions.

[0252] It can be understood that the length of vehicle 1000 is greater than the width of vehicle 1000. Vehicle 1000 has a larger accommodating space in the length direction, while the accommodating space in the width direction of vehicle 1000 is limited. By utilizing the relatively sufficient space on the front and rear sides of the battery 30 to set the extension part 2 and the mounting structure 3, the extension part 2 and the mounting structure 3 can be avoided from occupying the space on the left and right sides of the battery 30, so that the space saved in the left and right directions can be used to increase the size of the battery 30, thereby improving the size energy density of the battery 30.

[0253] Moreover, compared with the solution of setting the mounting structure on both side walls of the vehicle beam, since the portion of the extension portion 2 of some embodiments of the present application located on one side of the width direction of the vehicle beam 20 (such as the second direction Y) forms an angle with the length direction of the vehicle beam 20 (such as the first direction X), there is sufficient space on the extension portion 2 to set the mounting structure 3, so as to flexibly set the distribution position, number and structural form of the mounting structure 3 on the extension portion 2, which is beneficial to improve the installation strength of the larger-sized battery 30 mounted on the mounting structure 3, and improve the mounting reliability of the battery 30, thereby helping to increase the vehicle's 1000 single battery replacement range.

[0254] The structure of the mounting structure 3 is not limited, for example, it may include but is not limited to a mounting groove, a mounting hole, a mounting protrusion, a mounting pin, a mounting screw, etc., which are not limited here.

[0255] In some embodiments, please refer to Figures 3 and 4 again, the extension portion 2 on at least one side of the width direction of the vehicle beam 20 (such as the second direction Y) is configured as multiple and arranged at intervals along the length direction of the vehicle beam 20 (such as the first direction X), and a battery mounting space 4 is defined between two adjacent extension portions 2 along the length direction of the vehicle beam 20 (such as the first direction X).

[0256] That is, multiple extensions 2 are provided on at least one side of the beam 20 in the width direction (e.g., the second direction Y), and the multiple extensions 2 on the same side of the beam 20 in the width direction (e.g., the second direction Y) are spaced apart along the length direction (e.g., the first direction X) of the beam 20. It is worth noting that the width direction (e.g., the second direction Y) of the beam 20 coincides with the width direction of the vehicle 1000, i.e., the left-right direction of the vehicle 1000. Therefore, multiple extensions 2 spaced apart along the front-to-back direction can be provided on at least one of the left and right sides of the beam 20.

[0257] It can be understood that the mounting structure 3 on the extension portion 2 is used to mount the battery 30 in the battery mounting space 4, that is, when the battery 30 is connected to the mounting structure 3, at least part of the battery 30 can be accommodated in the battery mounting space 4, presenting a mounted state.

[0258] In the above technical solution, the two adjacent extension portions 2 along the length direction of the vehicle beam 20 (such as the first direction X) can serve as the outer wall of the battery mounting space 4 to provide a certain degree of protection for the battery 30, thereby reducing damage to the battery 30 and improving the reliability of the battery 30 in providing electrical energy to the vehicle 1000.

[0259] In addition, since the extension part 2 is configured as multiple and is arranged at intervals along the length direction of the vehicle beam 20 (such as the first direction X), it is beneficial to make full use of the space in the length direction of the vehicle 1000 to arrange more extension parts 2, so as to define a larger number of battery mounting spaces 4, thereby mounting a larger number of mounted batteries 30, thereby increasing the size of the battery 30 while also increasing the number of mounted batteries 30, further improving the cruising range of the vehicle 1000 on a single battery replacement.

[0260] For example, please refer to Figures 3 and 4 again. Four extensions 2 are provided on one side of the width of the vehicle beam 20. The four extensions 2 are arranged at intervals along the length direction of the vehicle beam 20 (such as the first direction X), and the four extensions 2 define three battery mounting spaces 4. Each battery mounting space 4 can mount at least one battery 30, and when the battery 30 is mounted on the mounting structure 3, at least part of the battery 30 is located in the battery mounting space 4. At this time, the two adjacent extensions 2 can serve as the outer wall of the battery mounting space 4 to protect the battery 30 to a certain extent, so as to reduce damage to the battery 30 and improve the reliability of the battery 30 in providing electrical energy to the vehicle 1000.

[0261] Of course, the number of extensions 2 in the above description is only for illustration. For example, the number of extensions 2 on the width side of the vehicle beam 20 may be three, five, or more, etc., which can be set according to the specific needs of the vehicle 1000.

[0262] When the battery mounting rack 10 includes multiple battery mounting spaces 4, the extension portion 2 between two battery mounting spaces 4 can be used to isolate the batteries 30 of two adjacent battery mounting spaces 4, thereby improving problems such as mutual collision and heat transfer between the batteries 30 of two adjacent battery mounting spaces 4. Of course, the battery mounting rack 10 can also include only one battery mounting space 4.

[0263] In some embodiments, the battery mounting space 4 extends through the height direction of the vehicle beam 20 (e.g., the third direction Z). "The battery mounting space 4 extends through the height direction of the vehicle beam 20" means that the battery mounting space 4 is open at both ends of the height direction of the vehicle beam 20 and is not obstructed by any structure on the battery mounting bracket 10. The height direction of the vehicle beam 20 is consistent with the height direction of the vehicle 1000.

[0264] Thus, when the battery 30 is mounted in the battery mounting space 4, the battery 30 can be free from the battery mounting frame 10 on both sides in the height direction of the vehicle 1000. For example, the extension portion 2, the main body 1, and the mounting structure 3 do not occupy the space of the battery 30 in the height direction of the vehicle 1000, thereby improving the space utilization of the battery 30 in the height direction of the vehicle 1000, which is conducive to increasing the size of the battery 30 in the height direction of the vehicle 1000 and the size energy density of the battery 30, thereby increasing the cruising range of the vehicle 1000 on a single battery swap, and ensuring the height of the battery 30 from the ground, ensuring the passability of the vehicle 1000. In addition, it is also conducive to heat dissipation of the battery 30. Furthermore, it is also conducive to reducing the weight of the battery mounting frame 10 and reducing the vehicle-borne burden of the battery mounting frame 10.

[0265] 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.

[0266] In an embodiment of the present application, the battery mounting rack 10 includes a plurality of battery mounting spaces 4 sequentially arranged along the length direction of the vehicle beam 20 (such as the first direction X). The battery mounting rack 10 includes a plurality of battery mounting spaces 4. The battery mounting rack 10 is provided with a mounting structure 3 corresponding to each battery mounting space 4, so that each battery mounting space 4 can be used to mount a battery 30. The mounting structures 3 corresponding to different battery mounting spaces 4 can be independent of each other, so that each battery mounting space 4 can individually replace the mounted battery 30. Among them, the "correspondence" in the setting of the 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.

[0267] But it is 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 each other along the second direction Y are used to mount the same battery 30, the 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 mounting structure 3 is conducive to improving the battery replacement efficiency.

[0268] 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.

[0269] 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 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 to 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.

[0270] In some embodiments, referring to Figures 4-6, Figure 5 is a partial enlarged view of section A in Figure 4, and Figure 6 is an orthographic projection view of the connection between the battery mounting bracket 10 and the vehicle beam 20 shown in Figure 4. The mounting structure 3 is arranged on the side of the extension portion 2 facing the battery mounting space 4. That is, the extension portion 2 includes a mounting surface 23 facing the battery mounting space 4, and the mounting structure 3 is arranged on the side of the mounting surface 23 facing the battery mounting space 4.

[0271] In this way, the mounting structure 3 corresponds to the battery mounting space 4 that it faces, and the battery 30 is mounted in the battery mounting space 4 that the mounting structure 3 faces. This clarifies the correspondence between the 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 mounting structure 3 facing the battery mounting space 4, thereby conveniently mounting the battery 30. Furthermore, when there are multiple battery mounting spaces 4, the mounting structures 3 corresponding to different battery mounting spaces 4 are positioned differently and do not interfere with each other. This allows the mounting structure 3 corresponding to each battery mounting space 4 to have sufficient space for flexible placement, making it easier and more reliable for the mounting structure 3 to mount the battery 30. Thus, by arranging the mounting structure 3 on the side of the extension portion 2 facing the battery mounting space 4, the difficulty of arranging the mounting structure 3 is reduced, and sufficient space for flexible placement of the mounting structure 3 is provided, making it easier and more reliable for the mounting structure 3 to mount the battery 30.

[0272] In some embodiments, please refer to Figures 4 to 6 again. At least one extension portion 2 located in the middle of the multiple extension portions 2 is a common extension portion 2a. The common extension portion 2a has battery mounting spaces 4 on both sides of the length direction of the vehicle beam 20 (such as the first direction X), and mounting structures 3 are arranged on both sides of the battery mounting spaces 4 on both sides of the common extension portion 2a.

[0273] It is worth noting that "at least one central extension 2 among the plurality of extensions 2" refers to the remaining at least one extension 2 among the plurality of extensions 2 arranged along the length direction (e.g., the first direction X) of the beam 20, excluding the two extensions 2 on either side. For example, when four extensions 2 are provided on one width side of the beam 20, at least one of the two central extensions 2 is a common extension 2a. The common extension 2a has two mounting surfaces 23 facing the battery mounting spaces 4 on either side.

[0274] Therefore, when the number of battery mounting spaces 4 arranged at intervals along the length direction of the vehicle beam 20 (such as the first direction X) is fixed, the number of extension portions 2 arranged at intervals along the length direction of the vehicle beam 20 (such as the first direction X) can be reduced. For example, in the minimum case, the number of extension portions 2 on a single side of the width of the vehicle beam 20 can be one more than the number of battery mounting spaces 4, that is, only one extension portion 2 is set between two adjacent battery mounting spaces 4 along the length direction of the vehicle beam 20 (such as the first direction X), which is beneficial to reduce costs and reduce the load of the vehicle 1000.

[0275] 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 length direction (such as the first direction X) of the vehicle beam 20. In this way, each extension portion 2 may be provided with a mounting structure 3 corresponding only to the battery mounting space 4 on one side, thereby reducing the bearing force of each extension portion 2 on the battery and improving the mounting reliability of the battery 30.

[0276] In some embodiments, referring again to Figures 4-6 , the mounting structures 3 on either side of the common extension 2a in the longitudinal direction (e.g., the first direction X) of the beam 20 are misaligned in their orthographic projections on a projection plane perpendicular to the longitudinal direction (e.g., the first direction X) of the beam 20. That is, the mounting structures 3 on the two mounting surfaces 23 of the common extension 2a are misaligned in their orthographic projections along the longitudinal direction (e.g., the first direction X) of the beam 20. For example, the distance from any mounting structure 3 on one side of the common extension 2a to the beam 20 in the width direction (e.g., the second direction Y) of the beam 20 is different from the distance from any mounting structure 3 on the other side of the common extension 2a to the beam 20 in the width direction (e.g., the second direction Y) of the beam 20.

[0277] Therefore, by setting the mounting structures 3 on both sides of the common extension part 2a to be misaligned in the projection plane perpendicular to the length direction of the vehicle beam 20 (such as 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 mounting structures 3 on both sides of the common extension part 2a, stress concentration can be reduced to cause deformation, fracture and other problems of the extension part 2, thereby improving the service life of the common extension part 2a and improving the mounting reliability of the battery 30.

[0278] In some embodiments, referring again to Figures 4-6 , a mounting structure 3 is provided on the extensions 2 on both sides of the battery mounting space 4 in the longitudinal direction (e.g., the first direction X) of the vehicle beam 20. For example, the mounting surface 23 includes a first mounting surface 231 and a second mounting surface 232. The first mounting surface 231 and the second mounting surface 232 are respectively one side surface of two adjacent extensions 2 facing the same battery mounting space 4. The first mounting surface 231 is provided with a mounting structure 3 on the side facing the battery mounting space 4, and the second mounting surface 232 is also provided with a mounting structure 3 on the side facing the battery mounting space 4. The battery 30 in the battery mounting space 4 is connected to the two mounting structures 3 respectively.

[0279] Therefore, the extension parts 2 on both sides of the battery mounting space 4 in the length direction of the vehicle beam 20 (such as the first direction X) can both play the role of supporting the battery 30 in the battery mounting space 4, and the 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 increasing the service life of the common extension part 2a, thereby improving the mounting reliability of the battery 30.

[0280] Furthermore, in some embodiments, the mounting structures 3 on both sides of the battery mounting space 4 in the longitudinal direction (e.g., the first direction X) of the vehicle beam 20 are misaligned in their orthographic projections on a projection plane perpendicular to the longitudinal direction (e.g., the first direction X) of the vehicle beam 20. For example, the distance from any mounting structure 3 on one side of the battery mounting space 4 to the vehicle beam 20 in the width direction (e.g., the second direction Y) of the vehicle beam 20 is different from the distance from any mounting structure 3 on the other side of the battery mounting space 4 to the vehicle beam 20 in the width direction (e.g., the second direction Y) of the vehicle beam 20.

[0281] Therefore, by setting the 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 length direction of the vehicle beam 20 (such as the first direction X), it is further beneficial to disperse the force on the mounting structures 3 on both sides, and further improve the problems of deformation and fracture of the extension part 2 caused by stress concentration.

[0282] In addition, when the mounting structures 3 on both sides of the common extension portion 2a in the longitudinal direction of the vehicle beam 20 (such as the first direction X) are misaligned in their orthographic projections on the projection plane perpendicular to the longitudinal direction of the vehicle beam 20 (such as the first direction X), and the mounting structures 3 on both sides of the battery mounting space 4 in the longitudinal direction of the vehicle beam 20 (such as the first direction X) are misaligned in their orthographic projections on the projection plane perpendicular to the longitudinal direction of the vehicle beam 20 (such as the first direction X), multiple extension portions 2 can be constructed with the same structure to help reduce costs and reduce production processes.

[0283] Of course, the present application is not limited to this. For example, the mounting structures 3 on both sides of the common extension portion 2a in the longitudinal direction of the vehicle beam 20 (such as the first direction X) can also be set so that the orthographic projections on the projection plane perpendicular to the longitudinal direction of the vehicle beam 20 (such as the first direction X) coincide. At this time, the orthographic projections of the mounting structures 3 on both sides of the battery mounting space 4 in the longitudinal direction of the vehicle beam 20 (such as the first direction X) on the projection plane perpendicular to the longitudinal direction of the vehicle beam 20 (such as the first direction X) can also coincide, thereby simplifying processing and reducing costs.

[0284] In some embodiments, referring to FIG. 4 and FIG. 5 , a plurality of mounting structures 3 are provided on one side of the extension portion 2 facing the battery mounting space 4 , and at least two of the mounting structures 3 are spaced apart along the width direction (eg, the second direction Y) of the vehicle beam 20 .

[0285] In this way, it is beneficial to fully utilize the space in the width direction of the vehicle beam 20 (such as the second direction Y) and arrange more mounting structures 3, thereby enhancing the mounting stability of the battery 30, or increasing the number of batteries 30 mounted in the battery mounting space 4.

[0286] In some embodiments, referring to FIG5 , the extension portion 2 includes a mounting edge 24 that protrudes toward the battery mounting space 4, and the mounting structure 3 is located on the mounting edge 24. For example, the mounting edge 24 protrudes along the length direction of the vehicle beam 20 (e.g., the first direction X) toward the interior of the battery mounting space 4.

[0287] In this way, by setting the mounting edge 24, it is helpful to reduce the difficulty of setting the mounting structure 3, and it is easy to realize that the mounting structure 3 is located on the side of the extension part 2 facing the battery mounting space 4. Moreover, the mounting edge 24 can play a certain direct or indirect supporting role on the battery 30 to enhance the mounting stability of the battery 30.

[0288] 4 and 5 , in some embodiments, the mounting edge 24 is located at the lower edge of the extension portion 2 in the height direction of the vehicle beam 20 (e.g., the third direction Z). The height direction of the vehicle beam 20 (e.g., the third direction Z) is consistent with the height direction of the vehicle 1000, i.e., the direction of gravity.

[0289] As a result, the mounting structure 3 is set at a lower height, which is conducive to reducing the difficulty of maintaining the mounting structure 3, and is conducive to the loading connection between the mounting structure 3 and the battery 30, and improves the compactness of the fit between the battery 30 and the extension part 2, reduces space waste, and utilizes the saved space to further increase the size of the battery 30, thereby further improving the size energy density of the battery 30.

[0290] For example, when a tool is used to extend upward to the position of the mounting structure 3 to perform the mounting connection between the mounting structure 3 and the battery 30, the raised position of the tool is lower than the extension part 2, so that the lifting height of the tool can be reduced, and the tool does not need to be extended between the battery 30 and the extension part 2. There is no need to increase the gap between the battery 30 and the extension part 2 to meet the tool's insertion requirements, thereby reducing space waste and utilizing the saved space to further increase the size of the battery 30, thereby further improving the size energy density of the battery 30.

[0291] In some embodiments, please refer to Figures 4 and 5, the length direction of the mounting edge 24 is the same as the width direction of the vehicle beam 20 (such as the second direction Y), and a plurality of mounting structures 3 are arranged at intervals along the length direction of the mounting edge 24.

[0292] Therefore, since the length direction of the mounting edge 24 is the same as the width direction of the vehicle beam 20 (such as the second direction Y), it is beneficial to reduce the processing difficulty of the mounting edge 24, so that the mounting edge 24 has a larger length dimension and a larger number of mounting structures 3 are set. Multiple mounting structures 3 are set along the length direction of the mounting edge 24, which is beneficial to enhance the mounting stability of the battery 30, or to increase the number of batteries 30 mounted on the mounting edge 24.

[0293] In some embodiments, please refer to Figure 7, which is a partially enlarged view of a battery mounting rack 10 of another embodiment of the present application. The length direction of the mounting edge 24 is the same as the width direction of the vehicle beam 20 (such as the second direction Y), and the mounting structure 3 on the mounting edge 24 is configured as one and extends along the length direction of the mounting edge 24.

[0294] Therefore, by only setting one mounting structure 3 on the mounting edge 24, it is helpful to reduce the processing difficulty of the mounting structure 3, and the mounting structure 3 extends along the length direction of the mounting edge 24, that is, the length direction of the mounting structure 3 is consistent with the length direction of the mounting edge 24, so that the mounting structure 3 is larger in size, has a larger force-bearing area, or has more connection positions, so as to facilitate simultaneous connection with multiple connection structures on the battery 30, improve the mounting reliability of the battery 30, or facilitate simultaneous mounting of multiple batteries 30.

[0295] In some embodiments, an extension portion 2 is disposed on one side of the beam 20 in the width direction (e.g., the second direction Y). It is worth noting that the width direction (e.g., the second direction Y) of the beam 20 coincides with the width direction of the vehicle 1000, e.g., the left-right direction of the vehicle 1000. For example, the extension portion 2 may be disposed on the left side of the beam 20, or on the right side of the beam 20.

[0296] Therefore, by arranging the extension portion 2 only on one side of the vehicle beam 20 in the width direction (such as the second direction Y), the force transmitted to the vehicle beam 20 by the extension portion 2 on which the battery 30 is mounted can be reduced, thereby improving the connection reliability between the extension portion 2 and the vehicle beam 20, and improving the connection reliability between the vehicle beams 20, thereby improving the mounting reliability of the battery 30.

[0297] In some embodiments, referring to Figures 3 and 4 , an extension 2 is disposed on each of two sides of the beam 20 in the width direction (e.g., the second direction Y). In other words, a plurality of extensions 2 are provided on the beam 20, with at least two of the plurality of extensions 2 located on either side of the beam 20 in the width direction (e.g., the second direction Y). It is worth noting that the width direction (e.g., the second direction Y) of the beam 20 coincides with the width direction of the vehicle 1000, i.e., the left-right direction of the vehicle 1000. For example, an extension 2 is provided on the left side of the beam 20, and an extension 2 is also provided on the right side of the beam 20.

[0298] Therefore, by providing extension portions 2 on both sides of the vehicle beam 20 in the width direction (such as the second direction Y), the extension portions 2 on both sides of the vehicle beam 20 can be used to mount the batteries 30 respectively. For example, the two parts of the same battery 30 located on both sides in the width direction of the vehicle beam 20 can be mounted respectively, or the two batteries 30 located on both sides in the width direction of the vehicle beam 20 can be mounted respectively, thereby increasing the mounting strength of the battery 30 or increasing the number of mounted batteries 30.

[0299] In some embodiments, referring to Figures 3 and 4, the extension portion 2 includes a first extension portion 21 and a second extension portion 22 respectively arranged on both sides of the width direction (such as the second direction Y) of the vehicle beam 20. The extension directions of the first extension portion 21 and the second extension portion 22 are the same, and, when projected along the extension direction of the first extension portion 21, the projections of the first extension portion 21 and the second extension portion 22 overlap.

[0300] It is worth noting that the width direction of the beam 20 (e.g., the second direction Y) is consistent with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. For example, the first extension portion 21 and the second extension portion 22 both extend along the width direction of the beam 20 (e.g., the second direction Y), or the first extension portion 21 and the second extension portion 22 both extend in a direction oblique to the width direction of the beam 20 and have the same inclination angle.

[0301] Therefore, by setting the extension directions of the first extension part 21 and the second extension part 22 to be the same, and the projections of the first extension part 21 and the second extension part 22 along the extension direction of the first extension part 21 overlap, the first extension part 21 and the second extension part 22 can simultaneously mount the two parts of the same battery 30 located on both sides of the width direction of the vehicle beam 20. In this way, the size of the battery 30 can be made larger to reduce the number of batteries 30 and reduce the complexity of battery replacement.

[0302] In some embodiments, referring to Figures 3 and 4 , when multiple extensions 2 are provided along the length direction (e.g., first direction X) of the beam 20 on at least one side in the width direction (e.g., second direction Y), the battery mounting bracket 10 further includes a reinforcement portion 5 , which is used to connect at least two extensions 2 located on the same side of the beam 20 in the width direction (e.g., second direction Y). It is worth noting that this embodiment is applicable to both the situations where "at least one extension 2 is provided on each of the two sides in the width direction of the beam 20" and "an extension 2 is provided on one side in the width direction of the beam 20." Furthermore, the at least two extensions 2 connected by the reinforcement portion 5 may be adjacent or non-adjacent.

[0303] In addition, it is worth noting that the width direction of the beam 20 (e.g., the second direction Y) is consistent with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. For example, at least two extensions 2 on the left side of the beam 20 are connected by the reinforcement 5, and / or at least two extensions 2 on the right side of the beam 20 are connected by the reinforcement 5.

[0304] 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 .

[0305] In some embodiments, the reinforcement portion 5 and the main body 1 are positioned on either side of the extension portion 2 in the width direction (e.g., the second direction Y) of the vehicle beam 20. This allows the two extension portions 2 defining the battery mounting space 4 to be connected at both ends in the width direction (e.g., the second direction Y) of the vehicle beam 20 via the main body 1 and the reinforcement portion 5, respectively. This creates a ring-shaped structure around the battery mounting space 4, providing greater structural strength, improved mounting reliability for the battery 30, and more comprehensive circumferential protection for the battery 30. Furthermore, the location of the mounting structure 3 can be flexibly selected.

[0306] In some embodiments, referring to FIG5 , the height of the extension portion 2 in the height direction of the vehicle beam 20 (e.g., the third direction Z) decreases as it moves away from the vehicle beam 20. It is worth noting that the “decreasing trend” can be a gradual decrease or a stepwise decrease.

[0307] Therefore, by setting the height of the extension part 2 to decrease in the direction away from the vehicle beam 20, the height of the area of ​​the extension part 2 away from the vehicle beam 20 is smaller, that is, the height of the end of the extension part 2 connected to the vehicle beam 20 is relatively large, while the height of the end of the extension part 2 away from the vehicle beam 20 is relatively small, thereby enhancing the connection strength between the extension part 2 and the vehicle beam 20, improving the reliability of the extension part 2 for mounting the battery 30, and reducing the weight of the extension part 2, thereby reducing the load of the vehicle 1000.

[0308] When the mounting structure 3 is located at the lower edge of the extension portion 2 in the height direction of the vehicle beam 20 (such as the third direction Z), for example, on the mounting edge 24, and the mounting edge 24 is located at the lower edge of the extension portion 2, the lower edge of the extension portion 2 can be configured to extend horizontally, while the upper edge of the extension portion 2 in the height direction of the vehicle beam 20 (such as the third direction Z) decreases away from the vehicle beam 20. It is worth noting that the "decreasing trend" can be a gradual decrease or a step-by-step decrease. This helps to keep the mounting structures 3 at the same level, thereby facilitating the mounting operation of the battery 30.

[0309] In some embodiments, as shown in FIG7 , the extension portion 2 is further provided with reinforcing ribs 25. The structural form of the reinforcing ribs 25 is not limited and can be, for example, linear, curved, or cross-shaped. Thus, the provision of the reinforcing ribs 25 helps to enhance the structural strength of the extension portion 2 and improve the deformation problem of the extension portion 2 under stress.

[0310] For example, under normal circumstances, the farther the extension part 2 is from the main body part 1, the easier it is to deform. At least part of the reinforcing ribs 25 can be arranged close to the middle of the extension part 2 in the width direction of the vehicle beam 20 (such as the second direction Y), that is, it is in the center or approximately in the center as a whole, for example, it can be in the position range between 1 / 3-2 / 3 of the extension part 2 in the width direction of the vehicle beam 20 (such as the second direction Y). While reducing the number of reinforcing ribs 25, the structural strength of the extension part 2 can be better improved, and the reliability of the extension part 2 for mounting the battery 30 can be improved.

[0311] For example, when the battery 30 is mounted on the mounting structure 3 of the extension part 2, the position of the mounting structure 3 of the extension part 2 is subjected to concentrated force and is prone to deformation and damage. Therefore, at least part of the reinforcing ribs 25 can be arranged along the height direction of the vehicle beam 20 (such as the third direction Z) corresponding to the mounting structure 3, so that the structural strength of the extension part 2 can be better improved while reducing the number of reinforcing ribs 25, thereby improving the reliability of the extension part 2 for mounting the battery 30.

[0312] For example, when the extension portion 2 is provided with multiple mounting structures 3, at least some of the reinforcing ribs 25 are arranged between two adjacent mounting structures 3 along the height direction (e.g., the third direction Z) of the vehicle beam 20. When a battery 30 is mounted on the mounting structure 3 of the extension portion 2, the mounting structure 3 of the extension portion 2 is subjected to concentrated stress, making it susceptible to deformation and damage. By arranging at least some of the reinforcing ribs 25 between two adjacent mounting structures 3, the structural strength of the extension portion 2 between the two adjacent mounting structures 3 can be enhanced, improving the problem of stress concentration and fracture between the two adjacent mounting structures 3, and improving the reliability of the extension portion 2 for mounting the battery 30.

[0313] 5 , a first weight-reducing structure 26 is provided on the extension portion 2. For example, the first weight-reducing structure 26 may include but is not limited to a weight-reducing hole, a weight-reducing groove, or a thinning process.

[0314] In this way, by providing the first weight-reducing structure 26 , the weight of the extension portion 2 can be reduced, thereby facilitating a lightweight design of the battery mounting rack 10 .

[0315] In some embodiments, the extension portion 2 is entirely located on one side of the vehicle beam 20 in the width direction (such as the second direction Y), and the frame assembly 100 further includes: a main body 1 connected to the vehicle beam 20 , and the extension portion 2 is connected to the main body 1 .

[0316] Thus, by providing the main body 1, the extension 2 can be connected to the beam 20 through the main body 1, thereby reducing the difficulty of installing the extension 2. Moreover, by arranging the extension 2 on one side of the beam 20 in the width direction (e.g., the second direction Y), the space in the width direction of the beam 20 can be fully utilized to mount the battery 30, thereby facilitating an increase in the size of the battery 30. In addition, when multiple extensions 2 are provided, for example, the multiple extensions 2 can be first provided on the main body 1, and then the main body 1 can be connected to the beam 20. This simplifies the assembly steps and reduces the difficulty of assembly. Moreover, when installing the extension 2 on beams 20 of different sizes, only the main body 1 needs to be adjusted, thereby enhancing the adaptability of the extension 2.

[0317] The main body 1 and the extension 2 can be integrally formed to simplify production steps and reduce production costs. Alternatively, the main body 1 and the extension 2 can be formed separately and connected by assembly, such as welding or screw connection, thereby reducing the difficulty of processing each part.

[0318] In some embodiments, the main body 1 spans the vehicle beam 20, such that the extension portion 2 is connected to both sides of the main body 1 in the width direction of the vehicle beam 20 (e.g., the second direction Y). "The main body 1 spans the vehicle beam 20" includes but is not limited to the main body 1 spanning along the width direction of the vehicle beam 20, or the main body 1 spanning along a direction intersecting the width direction of the vehicle beam 20.

[0319] Thus, by arranging the main body 1 across the beam 20, the main body 1 can simultaneously connect to the extensions 2 on both sides of the beam 20 in the width direction, thereby further improving the assembly efficiency of the battery mounting frame 10 and the beam 20. This also helps to improve the overall structural strength of the battery mounting frame 10. Moreover, since the extensions 2 are provided on both sides of the beam 20 to mount the batteries 30, the space on both sides of the width of the beam 20 can be fully utilized to mount the batteries 30, which helps to increase the size and number of batteries 30, thereby increasing the range of the vehicle 1000 per single battery replacement.

[0320] Fourthly, the present application provides a vehicle 1000, comprising a battery 30 and a frame assembly 100 as in any of the above-described embodiments, wherein the battery 30 is mounted to the frame assembly 100. Thus, the provision of the frame assembly 100 in the embodiment of the present application can increase the size and quantity of the battery 30, thereby facilitating an increase in the range of the vehicle 1000 per single battery swap.

[0321] In some embodiments, referring to Figures 9 and 10 , the battery 30 includes an upper battery portion 30a and a lower battery portion 30b. The upper battery portion 30a is higher than the bottom surface of the vehicle beam 20, while the lower battery portion 30b is lower than the bottom surface of the vehicle beam 20. Thus, the upper battery portion 30a can occupy the space on both sides of the width of the vehicle beam 20, improving space utilization. This allows the size of the battery 30 in the height direction of the vehicle 1000 to be increased, thereby improving the energy density of the battery 30. Furthermore, the mounting structure 30c is detachably connected to the mounting structure 3, which makes it easier to replace the battery 30 and improves battery replacement efficiency.

[0322] Furthermore, in some embodiments, referring to Figures 9 and 10, the extension portion 2 can be higher than the bottom surface of the vehicle beam 20, the mounting structure 3 is arranged at the lower edge of the extension portion 2, and the battery 30 is provided with a mounting structure 30c at a position between the upper battery portion 30a and the lower battery portion 30b, and the mounting structure 30c is detachably connected to the mounting structure 3. Therefore, when the battery 30 is mounted on the battery mounting rack 10, the upper part 30a of the battery can extend into the battery mounting space 4, and the lower part 30b of the battery is located below the battery mounting space 4. The extension part 2 can be used to protect the upper part 30a of the battery to reduce the risk of damage to the battery 30, which is beneficial to extending the service life of the battery 30. At the same time, the height of the extension part 2 can be less than the height of the battery 30, and the height of the extension part 2 can be reduced, thereby reducing the weight and cost of the battery mounting rack 10. In addition, the mounting structure 30c is set between the upper part 30a of the battery and the lower part 30b of the battery, so that the mounting structure 3 located at the lower edge of the extension part 2 can be connected to the mounting structure 30c, which is beneficial to the battery replacement operation.

[0323] The connection method between the installation structure 30c and the mounting structure 3 includes but is not limited to: connection by bolts, or snap connection, or plug connection, or magnetic attraction, etc.

[0324] 9 and 10 , in the longitudinal direction of the beam 20 (e.g., the first direction X), the size of the upper battery portion 30 a is smaller than the size of the lower battery portion 30 b, so as to form a step surface 30 d between the upper battery portion 30 a and the lower battery portion 30 b, and the step surface 30 d stops at the bottom of the extension portion 2.

[0325] 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 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 mounting structure 3, step surface 30d abuts the bottom of extension portion 2.

[0326] Therefore, when the battery 30 is actually installed, the upper portion 30a of the battery can be installed from the bottom up, and the stop formed by the bottom of the extension 2 and the stepped surface 30d can be used to indicate that the battery 30 is properly installed, thereby preventing the battery 30 from being excessively squeezed upward and hitting the bottom of the vehicle, 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.

[0327] In some embodiments, referring to Figures 11 and 12, the battery 30 includes two battery side portions 30e and a battery central portion 30f. In the width direction of the vehicle beam 20 (such as the second direction Y), 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 is continuous along the length direction of the vehicle beam 20 (such as the first direction X) and has an open top.

[0328] Exemplarily, the bottom surface of the central portion 30f of the battery is flush with the bottom surface of the side portion 30e of the battery, so that the bottom surface of the entire battery 30 is a planar structure, which is conducive to fully utilizing the space and facilitating the design of the height of the battery 30 from the ground.

[0329] Thus, when the battery 30 is installed with the vehicle bottom facing upward, at least a portion of the beam 20 can be accommodated within the clearance groove 30g and positioned above the battery center portion 30f. The upper portions of the two battery side portions 30e can be positioned on either side of the width of the beam 20. This fully utilizes the space on both sides of the width of the beam 20 to accommodate a larger battery 30. Therefore, the battery 30 has a clever structure. By avoiding the beam 20 and fully utilizing the space on both sides of the width of the beam 20, the overall size of the battery 30 can be increased, thereby improving the size and energy density of the battery 30.

[0330] In some embodiments, referring to Figures 11 and 12 , at least one of the battery side portion 30e and the battery central portion 30f is detachably connected to the mounting structure 3. "At least one of the battery side portion 30e and the battery central portion 30f is detachably connected to the mounting structure 3" includes: the battery side portion 30e is detachably connected to the mounting structure 3, or the battery central portion 30f is detachably connected to the mounting structure 3, or the battery side portion 30e and the battery central portion 30f are respectively detachably connected to corresponding mounting structures 3.

[0331] Among them, the battery side 30e can be detachably connected to the 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.

[0332] Among them, the central part 30f of the battery can be detachably connected to the mounting structure 3 through the mounting structure 30c on the central part 30f of the battery. The position of the mounting structure 30c on the central part 30f of the battery is not limited, for example, it can be located in the middle, upper or lower part of the central part 30f of the battery.

[0333] Among them, the connection methods of the battery side portion 30e and / or the battery central portion 30f with the 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.

[0334] When both battery side portions 30e are connected to the mounting structure 3, or when both the battery side portions 30e and the battery center portion 30f are connected to the mounting structure 3, the installation stability of the battery 30 can be improved. In addition, detachably connecting at least one of the battery side portions 30e and the battery center portion 30f to the mounting structure 3 facilitates increased design flexibility for the battery 30.

[0335] 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.

[0336] In some embodiments of the present application, as shown in Figures 13 and 14, the battery mounting bracket 10 of any embodiment of the present application may further include a docking structure 6, which is used to connect the body of the vehicle 100 and the docking battery 30, so that the battery 30 and the vehicle body form a circuit and / or fluid circuit.

[0337] Among them, when the battery 30 is mounted on the frame body 10a through the mounting structure 3, the battery 30 can dock with the docking structure 6 to form a circuit and / or liquid circuit connection. The docking structure 6 also has a connection relationship with the vehicle body and also forms a circuit and / or liquid circuit connection, thereby satisfying the battery 30's need to achieve circuit and / or liquid circuit connection with the vehicle body through docking with the docking structure 6.

[0338] It is worth noting that the connection method between the docking structure 6 and the vehicle body is not limited. For example, the connection can be achieved by docking using docking terminals, or by plugging in wires and / or pipes. In addition, the totality of the vehicle 1000, excluding the battery 30 and the battery mounting bracket 10, can be understood as the vehicle body, and the vehicle beam 20 is a part of the vehicle body.

[0339] For example, when the docking structure 6 is used to achieve electrical connectivity, it can be used to transfer current between the vehicle 1000 and the battery 30, enabling the battery 30 to power the vehicle 1000 and the vehicle 1000 to control the battery 30. For example, when the docking structure 6 is used to achieve fluid connectivity, it can be used to transfer heat between the thermal management system of the vehicle 1000 and the battery 30, thereby utilizing the thermal management system to regulate the temperature of the battery 30 to improve the operational reliability and safety of the battery 30. Alternatively, the thermal management system can be used to absorb waste heat from the battery 30 to meet the heat source requirements of the heat pump air conditioning system of the vehicle 1000, etc., which will not be further described here.

[0340] Thus, by providing the docking structure 6 on the battery mounting frame 10, the structural design of the battery mounting frame 10 can meet the requirements for electrical and / or fluid connectivity between the battery 30 and the vehicle body, thereby simplifying the structural design of the vehicle body and the battery 30. It should be noted that the location of the docking structure 6 is not limited and can be selected based on the specific configuration of the battery mounting frame 10.

[0341] In some embodiments, as shown in FIG13 , the docking structure 6 can be provided on the main body 1, and the mounting structure 3 can be provided on the extension 2. The main body 1 and the extension 2 are connected to form the frame body 10a, thereby indicating that the docking structure 6 and the mounting structure 3 are both integrated into the frame body 10a. When such a battery mounting rack 10 is used to install the battery 30 on the vehicle body, the mounting installation of the battery 30 can be achieved through the mounting structure 3 integrated on the frame body 10a, and the circuit and / or fluid connection between the battery 30 and the vehicle body can be achieved through the docking structure 6 integrated on the frame body 10a, thereby eliminating the need to connect wires and pipes, simplifying the tedious battery replacement operation, and improving the battery replacement efficiency. Moreover, since the mounting structure 3 and the docking structure 6 are both integrated into the frame body 10a, the mounting connection position of the battery 30 is consistent with the reference reference of the water and electricity docking position, that is, the reference reference is the frame body 10a, thereby improving the success rate of battery replacement.

[0342] In some embodiments, the docking structure 6 may include a first docking structure and a second docking structure, wherein the first docking structure is configured to dock with a circuit terminal on the battery 30, and the second docking structure is configured to dock with a fluid port on the battery 30. The relative positions of the first docking structure and the second docking structure are not limited; for example, they may be spaced apart in the horizontal direction, such as left and right, or front and back, so that the first docking structure and the second docking structure do not interfere with each other when docked. Of course, the first docking structure and the second docking structure described above are merely examples of a portion of the docking structure 6 and do not constitute a limitation thereto.

[0343] In some embodiments, as shown in Figures 13 and 14, the main body 1 has a beam avoidance groove 13, which has an opening extending through the beam 20 along the length direction (e.g., the first direction X), and the docking structure 6 is located within the beam avoidance groove 13. In the embodiments of the present application, the length direction of the vehicle body, the length direction of the vehicle 1000, and the length direction of the beam 20 are all consistent; the width direction of the vehicle body, the width direction of the vehicle 1000, and the width direction of the beam 20 are all consistent; and the height direction of the vehicle body, the height direction of the vehicle 1000, and the height direction of the beam 20 are all consistent.

[0344] Thus, by providing the beam avoidance groove 13 in the main body 1, when the main body 1 is connected to the vehicle body, at least a portion of the beam 20 can extend into the beam avoidance groove 13. The extension direction of the beam 20 is the same as the through-direction of the opening, thus preventing interference between the battery mounting bracket 10 and the beam 20. This improves the compactness of the fit between the battery mounting bracket 10 and the beam 20, facilitates the use of the space near the beam 20 to install the battery 30, and thus helps increase the size and dimensional energy density of the battery 30. Furthermore, by arranging the docking structure 6 within the beam avoidance groove 13, the space within the beam avoidance groove 13 can be fully utilized, thereby improving space utilization and facilitating the reduction of the space occupied by the docking structure 6 in other locations of the battery mounting bracket 10, thereby increasing the size and dimensional energy density of the battery 30.

[0345] Furthermore, the docking structure 6 is protected by the inner wall of the beam avoidance groove 13, reducing the probability of damage to the docking structure 6 due to bumps and collisions, improving the problem of corrosion and failure of the docking structure 6 due to mud and water, etc., improving the reliability and stability of the docking, and reducing the risk of electrical failure caused by erosion of the docking structure 6 by mud and splashing water. Furthermore, the docking structure 6 does not occupy space outside the beam 20 and does not interfere with the connection between the battery mounting bracket 10 and the beam 20 or the battery 30. At the same time, it helps to shorten the distance between the vehicle body and the docking structure 6, thereby reducing the difficulty of connecting the vehicle body and the docking structure 6.

[0346] In some embodiments, as shown in Figures 13 and 14 , the main body 1 includes a plurality of first main body walls 11 spaced apart along the length direction (e.g., first direction X) of the vehicle beam 20. A clearance opening 15 is formed between two adjacent first main body walls 11. The docking interface (e.g., circuit interface and / or fluid interface) of the docking structure 6 is higher than the first main body wall 11 and is provided corresponding to the clearance opening 15. Here, the height direction of the vehicle body is defined as the up-down direction, which is consistent with the height direction of the vehicle 1000 and is both up-down in the direction of gravity.

[0347] Thus, because the docking interface of the docking structure 6 is higher than the first main body wall 11, the docking interface of the docking structure 6 is higher off the ground, providing better protection. Furthermore, the height setting of the docking interface of the docking structure 6 helps save space, thereby increasing the height dimension of the battery 30, improving the compactness of the fit between the battery mounting rack 10 and the battery 30, and fully utilizing space to increase the size and dimensional energy density of the battery 30. Furthermore, by providing the avoidance opening 15, when the battery 30 is mounted on the battery mounting rack 10, a portion of the battery 30 can extend upward into the avoidance opening 15 and dock with the docking interface of the docking structure 6, thereby meeting docking requirements.

[0348] In some embodiments, as shown in Figures 13 and 14, the docking structure 6 includes a load-bearing frame 61 and a docking device 62. The load-bearing frame 61 includes a load-bearing portion 611 and a support leg portion 612. The docking device 62 is provided on the load-bearing portion 611. The support leg portion 612 extends from both ends of the load-bearing portion 611 in the length direction of the vehicle beam 20 (such as the first direction X) toward the first main wall 11 and is connected to the first main wall 11.

[0349] In the above technical solution, the docking device 62 is arranged on the load-bearing portion 611, and the support leg portions 612 are extended from both ends of the load-bearing portion 611 in the length direction of the vehicle beam 20 (such as the first direction X) toward the first main body portion 1 and connected to the first main body wall 11. In this way, the load-bearing portion 611 can be spaced apart from the first main body wall 11, so that the load-bearing frame 61 can be constructed into a shape that can avoid the battery 30 upward, and it is convenient to increase the setting height of the docking device 62, so as to save space and increase the height size of the battery 30.

[0350] Moreover, when the length direction of the vehicle beam 20 (such as the first direction X) is the length direction of the vehicle 1000, the two support leg portions 612 are arranged on both sides of the load-bearing portion 611 in the length direction of the vehicle beam 20 (such as the first direction X), which can only occupy the space of the battery 30 in the length direction of the vehicle 1000. The space in this direction is relatively sufficient, which can reduce the space occupied by the battery 30 in the width direction of the vehicle 1000, which is beneficial to improving the size and energy density of the battery 30 in the width direction of the vehicle 1000.

[0351] In some embodiments, as shown in FIG. 13 and FIG. 14 , the bearing portion 611 has a third weight-reducing structure 613 , and / or a first reinforcement structure 614 is provided at the connection between the leg portion 612 and the bearing portion 611 .

[0352] Thus, by providing the third weight-reducing structure 613 on the bearing portion 611, the weight of the bearing portion 611 is reduced, thereby reducing the weight of the docking structure 6, thereby achieving a lightweight design of the docking structure 6. The third weight-reducing structure 613 may include, but is not limited to, weight-reducing holes, weight-reducing grooves, or thinning treatments.

[0353] Thus, by providing the first reinforcement structure 614 at the connection between the load-bearing portion 611 and the leg portion 612, the structural strength of the connection between the load-bearing portion 611 and the leg portion 612 is enhanced, and the possibility of fracture at the connection between the leg portion 612 and the load-bearing portion 611 is reduced, thereby facilitating a reduction in the thickness of the load-bearing portion 611 and the leg portion 612, thereby achieving a lightweight design of the docking structure 6. The first reinforcement structure 614 may include, but is not limited to, reinforcement ribs, strip-shaped reinforcement protrusions, or partially thickened portions of the extension portion 2. When the first reinforcement structure 614 is configured as a reinforcement rib, the structural form of the reinforcement rib is not limited, and may be, for example, linear, curved, or cross-shaped.

[0354] In some embodiments, as shown in Figures 13 and 14, the carrier 61 is an integrally formed part and is assembled and connected to the first main body wall 11. Therefore, by setting the carrier 61 as an integrally formed part, the difficulty of setting the carrier 61 is reduced, and the overall structural strength of the carrier 61 is ensured. In addition, the carrier 61 is assembled and connected to the first main body wall 11, which reduces the difficulty of assembling the carrier 61 and the first main body wall 11, thereby improving the production efficiency of the battery mounting rack 10.

[0355] In addition, the support frame 61 may not be an integrally formed part, for example, it may be an assembled connection between the support portion 611 and the leg portion 612. Here, "assembled connection" includes but is not limited to welding, bolting, clamping, or plugging.

[0356] In some embodiments, as shown in Figures 13 and 14, both the battery mounting spaces 4 and the avoidance openings 15 can be provided as a plurality of spaced apart locations along the length direction (e.g., the first direction X) of the vehicle beam 20, and the avoidance openings 15 correspond one-to-one with the battery mounting spaces 4 along the width direction (e.g., the second direction Y) of the vehicle beam 20, with each avoidance opening 15 correspondingly provided with a docking structure 6. Thus, when the battery 30 is relatively large, the portion of the battery 30 corresponding to the battery mounting space 4 can extend into the battery mounting space 4, and the portion of the battery 30 corresponding to the avoidance opening 15 can extend into the avoidance opening 15 to achieve docking with the docking structure 6. Moreover, by providing a plurality of avoidance openings 15, when a plurality of batteries 30 are mounted on the battery mounting rack 10, the connection requirements of the plurality of batteries 30 with the circuits and / or fluid paths of the vehicle body can be realized respectively through a plurality of docking structures 6, that is, each battery 30 can achieve the connection requirements with the circuits and / or fluid paths of the vehicle body through the docking of the corresponding docking structure 6, so that the vehicle 1000 can achieve separate connection with each battery 30 through the corresponding docking structure 6, which is conducive to each battery 30 being powered separately or being controlled separately by the vehicle body.

[0357] In some embodiments, referring to Figure 4, when one side of the main body 1 is provided with a plurality of battery mounting spaces 4 spaced apart along the length direction of the vehicle beam 20 (such as the first direction X), the docking structure 6 can be provided in plurality and spaced apart along the length direction of the vehicle beam 20 (such as the first direction X), and the plurality of docking structures 6 and the plurality of battery mounting spaces 4 are arranged opposite to each other along the second direction Y, and the second direction Y intersects with the length direction of the vehicle beam 20 (such as the first direction X) (for example, at an acute angle, an obtuse angle, or a right angle).

[0358] Therefore, when the size of the battery 30 is large, the part of the battery 30 corresponding to the battery mounting space 4 can extend into the battery mounting space 4, and the part corresponding to the docking structure 6 can dock with the docking structure 6. The distribution direction of the docking structure 6 does not occupy the space of the battery mounting space 4 in the length direction of the vehicle beam 20 (such as the first direction X), that is, while the docking structure 6 achieves docking with the battery 30, it will not occupy the space in the arrangement direction of multiple battery mounting spaces 4, which is beneficial to increase the number or size of the battery mounting spaces 4 arranged along the length direction of the vehicle beam 20 (such as the first direction X), improve space utilization, and enable the battery mounting rack 10 to mount more or larger batteries 30.

[0359] 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, the vehicle beam 20 may include two longitudinal beams 201 extending along the length direction of the vehicle beam 20 and at least one cross beam 202 extending along the width direction of the vehicle. The two longitudinal beams 201 are spaced apart along the width direction of the vehicle, and the cross beam 202 is connected between the two longitudinal beams 201. Because the vehicle beam 20 includes two longitudinal beams 201 extending along the length direction of the vehicle beam 20 (e.g., the first direction X) and spaced apart along the second direction Y, the second direction Y can be set to be orthogonal to the length direction of the vehicle beam 20 (e.g., the first direction X).

[0360] In some embodiments, when the vehicle beam 20 includes two longitudinal beams 201 extending along the length of the vehicle beam 20 and spaced apart along the width of the vehicle beam 20, the docking structure 6 can be positioned between the two longitudinal beams 201. This allows the two longitudinal beams 201 to provide some protection for the docking structure 6, thereby reducing damage to the docking structure 6 and extending its service life. Furthermore, the docking structure 6 can fully utilize the space between the two longitudinal beams 201, thereby improving space utilization and reducing the volume of the battery mounting bracket 10, thereby increasing the capacity of the battery 30. Furthermore, the portion of the docking structure 6 located between the two longitudinal beams 201 is protected by the two longitudinal beams 201, reducing the probability of damage to the docking structure 6 from collisions and improving the problem of corrosion failure of the docking structure 6 due to mud and water. This improves the reliability and stability of the docking connection and reduces the risk of electrical failure of the docking structure 6 due to erosion by mud and splashing water. Furthermore, the docking structure 6 does not occupy space outside the vehicle beam 20 and does not interfere with the fit of the battery mounting bracket 10 with the vehicle beam 20 and the battery 30.

[0361] In some embodiments, as shown in Figures 13 and 14, the docking interface of the docking structure 6 is higher than the bottom surface of the longitudinal beam 201 and is set downward. Therefore, since the docking interface of the docking structure 6 is higher than the bottom surface of the longitudinal beam 201, the docking interface of the docking structure 6 is at a greater height from the ground, which can obtain better protection. In addition, the height setting of the docking interface of the docking structure 6 is conducive to saving space, so as to increase the height dimension of the battery 30 so that at least part of the battery 30 can extend between the two longitudinal beams 201, improve the compactness of the battery mounting frame 10 and the battery 30, make full use of the space, and increase the size and dimensional energy density of the battery. Moreover, by setting the docking interface downward, the battery 30 can be mounted from the bottom up while being docked with the docking structure 6, thereby improving the efficiency of battery replacement.

[0362] In this way, the docking direction of the battery 30 when docking with the vehicle 1000 is arranged along the height direction of the vehicle 1000, and because the battery 30 is mounted on the vehicle 1000, the battery replacement movement direction of the battery 30 is also arranged along the height direction of the vehicle 1000, so that the docking direction of the battery 30 can coincide with the battery replacement movement direction, and there is no need to set up additional docking space in the length or width direction of the vehicle 1000 to improve space utilization, and the battery 30 can be mounted and docked in the same direction, thereby improving the battery replacement efficiency.

[0363] In some embodiments, as shown in Figures 13 and 14, the docking interface of the docking structure 6 is higher than the bottom surface of the longitudinal beam 201 and is set downward. Therefore, since the docking interface of the docking structure 6 is higher than the bottom surface of the longitudinal beam 201, the docking interface of the docking structure 6 is at a greater height from the ground, which can obtain better protection. In addition, the height setting of the docking interface of the docking structure 6 is conducive to saving space, so as to increase the height dimension of the battery 30 so that at least part of the battery 30 can extend between the two longitudinal beams 201, improve the compactness of the battery mounting frame 10 and the battery 30, make full use of the space, and increase the size and dimensional energy density of the battery. Moreover, by setting the docking interface downward, the battery 30 can be mounted from the bottom up while being docked with the docking structure 6, thereby improving the efficiency of battery replacement.

[0364] In this way, the docking direction of the battery 30 when docking with the vehicle 1000 is arranged along the height direction of the vehicle 1000, and since the battery 30 is mounted on the vehicle 1000, the battery replacement movement direction of the battery 30 is also arranged along the height direction of the vehicle 1000, so that the docking direction of the battery 30 can coincide with the battery replacement movement direction, and there is no need to set up additional docking space in the length or width direction of the vehicle 1000 to improve space utilization, and the battery 30 can be mounted and docked in the same direction, thereby improving the battery replacement efficiency.

[0365] In some embodiments, referring to FIG. 15 , the battery 30 includes two side battery portions 30e and a central battery portion 30f. In the width direction of the beam 20 (e.g., the second direction Y), the two side battery portions 30e are located on either side of the central battery portion 30f. The top surface of the central battery portion 30f is lower than the top surface of the side battery portions 30e, forming a clearance groove 30g between the two side battery portions 30e and the central battery portion 30f. The groove extends along the length direction of the beam 20 (e.g., the first direction X) and is open at the top. A docking portion 30h for docking with the docking structure 6 can be provided on the top of the central battery portion 30f.

[0366] Thus, when the battery 30 moves from bottom to top along the height direction of the vehicle 1000, the docking portion 30h of the battery 30 can be easily docked with the docking structure 6 between the two longitudinal beams 201, thereby reducing the difficulty of battery replacement operation, improving battery replacement efficiency, and saving space required for battery replacement operation. Furthermore, when the docking interface of the docking structure 6 is set downward, the battery 30 can be simultaneously docked with the docking structure 6 while being mounted on the mounting structure 3 from bottom to top. In this way, the docking space when the battery 30 is docked with the vehicle 1000 is arranged along the height direction of the vehicle 1000. Since the battery 30 is mounted on the vehicle 1000, the battery replacement movement space of the battery 30 is also arranged along the height direction of the vehicle 1000, so that the docking direction of the battery 30 can coincide with the battery replacement movement direction, thereby eliminating the need to set up additional docking space in the length or width direction of the vehicle 1000, thereby improving space utilization, and allowing the battery 30 to be replaced and docked simultaneously, thereby improving battery replacement efficiency.

[0367] 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.

[0368] 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.

[0369] In some embodiments, the operating voltage range of the battery replacement system is: 400V~750V.

[0370] 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.

[0371] In some embodiments, the dimensional tolerance of the battery replacement system is within ±10 mm.

[0372] 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.

[0373] In some embodiments, as shown in Figures 16 and 17, 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 18 and 19.

[0374] In some embodiments, referring to Figures 16-19, 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.

[0375] In some embodiments, referring to Figures 16-19, 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.

[0376] In some embodiments, referring to Figures 16-19, the dimension W of the battery replacement system along the vehicle width direction satisfies: 2300mm≤W≤2550mm.

[0377] In some embodiments, referring to Figures 16-19, the total height H of the battery replacement system satisfies: H≤680mm.

[0378] In some embodiments, referring to Figures 16-19, the length dimension L1 of the upper boss of the battery replacement system (such as the upper part 30a of the battery) satisfies: 600mm≤L1≤700mm.

[0379] In some embodiments, referring to Figures 16-19, 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.

[0380] In some embodiments, referring to Figures 16-19, 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.

[0381] In some embodiments, referring to Figures 16-19, 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.

[0382] In some embodiments, referring to Figures 16-19, the height dimension H2 of the upper middle boss of the battery replacement system (such as the upper part 30a of the battery central part 30f) satisfies: H2≤150mm.

[0383] 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.

[0384] 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.

[0385] 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.

[0386] 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.

[0387] 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.

[0388] 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.

[0389] In some embodiments, referring to FIG. 20 , 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.

[0390] In some embodiments, referring to FIG. 20 , 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.

[0391] In some embodiments, referring to FIG. 20 , in the width direction of the vehicle (eg, the second direction Y), the minimum width between the two second main body walls 12 (or the width of the avoidance opening 15 ) is N2 and satisfies: 660 mm ≤ N2 ≤ 680 mm.

[0392] In some embodiments, referring to Figure 21, 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).

[0393] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some or all of the technical features therein. These modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application. In particular, as long as there is no structural conflict, the various technical features mentioned in the various embodiments can be combined in any way. The present application is not limited to the specific embodiments disclosed herein, but includes all technical solutions that fall within the scope of the claims.
