[0002] Energy conservation and emission reduction are the key to the sustainable development of the automotive industry. Electric vehicles have become an important part of the sustainable development of the automotive industry due to their advantages in energy conservation and environmental protection. For electric vehicles, battery technology is an important factor related to their development. When the battery is installed on the vehicle, the space available for battery placement is limited, resulting in limited power and affecting the vehicle's range after a single battery replacement. Summary of the invention

[0003] 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.

[0004] In the first aspect, the present application provides a battery mounting bracket for mounting a battery to a vehicle beam, the battery mounting bracket comprising: a main body and an extension portion, the main body portion being used to be connected to the vehicle beam and extending along the length direction of the vehicle beam, the extension portion forming an angle with the extension direction of the main body portion and extending in a direction away from the main body portion, the extension portion being provided with a mounting structure, the mounting structure being used to mount the battery.

[0005] 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 vehicle width direction, which is beneficial to increase the size of the battery in the vehicle width direction, and is beneficial to flexibly setting 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.

[0006] 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.

[0007] In the above technical solution, it is beneficial to make full use of the space in the length direction of the vehicle to arrange more extension parts, so as to define more battery mounting spaces, thereby mounting more mounting batteries, so as to increase the battery size while increasing the number of mounted batteries, further improving the vehicle's single battery replacement range. At the same time, the two adjacent extension parts along the extension direction of the main body can serve as the outer wall of the battery mounting space to protect the battery to a certain extent, thereby reducing battery damage and improving the reliability of the battery in providing power to the vehicle.

[0008] In some embodiments, a mounting structure is arranged on a side of the extension portion facing the battery mounting space.

[0009] 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.

[0010] 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, and mounting structures are arranged on both sides of the battery mounting spaces of the common extension portion facing both sides.

[0011] 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 reduce costs and reduce the load of the vehicle.

[0012] In some embodiments, the mounting structures on both sides of the common extension portion 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.

[0013] 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, the stress concentration can be reduced to reduce the deformation, fracture and other problems of the common extension part, thereby improving the service life of the common extension part and improving the mounting reliability of the battery.

[0014] In some embodiments, mounting structures are provided on the extension portions on both sides of the battery mounting space in the extension direction of the main body.

[0015] 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, and 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.

[0016] 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.

[0017] In the above technical solution, by setting the mounting structures on both sides of the battery mounting space to be misaligned in the orthographic projection on the projection plane perpendicular to the extension direction of the main body, it is further beneficial for the mounting structures on both sides to disperse the force, and further improve the deformation and fracture of the extension part caused by stress concentration. In addition, when the mounting structures on both sides of the common extension part in the extension direction of the main body are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction of the main body, and the mounting structures on both sides of the battery mounting space in the extension direction of the main body are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction of the main body, multiple extension parts can be constructed as the same structure, so as to reduce costs and production processes.

[0018] In some embodiments, a plurality of mounting structures are provided on one side of the extension portion facing the battery mounting space, and at least two of the mounting structures are arranged at intervals along the length direction of the extension portion. In the above technical solution, it is beneficial to fully utilize the space in the length direction of the extension portion and arrange more mounting structures, thereby facilitating the mounting stability of the battery or increasing the number of batteries mounted in the battery mounting space.

[0019] In some embodiments, the extension portion includes a mounting edge protruding toward the battery mounting space, and the mounting structure is located on the mounting edge. In the above technical solution, by providing the mounting edge, it is helpful to reduce the difficulty of providing the mounting structure, and it is easy to achieve that the mounting structure is located on the side of the extension portion facing the battery mounting space, and the mounting edge can play a certain direct or indirect supporting role on the battery to enhance the mounting stability of the battery.

[0020] 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 relatively low height, which is conducive to reducing the difficulty of maintenance of the mounting structure, and is conducive to the loading connection between the mounting structure and the battery, and improves the compactness of the battery and the extension portion, reduces space waste, and further increases the size of the battery by saving space, thereby further improving the size energy density of the battery.

[0021] 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.

[0022] 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 helpful 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 helpful to enhance the mounting stability of the battery, or to increase the number of batteries mounted on the mounting edge.

[0023] 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.

[0024] In the above technical solution, by only setting 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.

[0025] In some embodiments, an extension portion is arranged on one side of the main body portion in a width direction.

[0026] 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 to the main body by the extension part on which the battery is mounted 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.

[0027] In some embodiments, the extension portion is disposed on each of both sides in the width direction of the main body portion.

[0028] In the above technical solution, by arranging extension parts on both sides of the width direction of the main body, only by connecting one main body to the vehicle beam, it is possible to make both sides of the vehicle beam have extension parts, so that the extension parts on both sides can be used to mount batteries respectively. For example, two parts of the same battery located on both sides of the width direction of the vehicle beam can be mounted respectively, or 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.

[0029] 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, the extension directions of the first extension portion and the second extension portion are the same, and when projected along the extension direction of the first extension portion, the projections of the first extension portion and the second extension portion overlap.

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.

[0031] In some embodiments, the battery mounting bracket further includes a reinforcing portion, and the reinforcing portion is used to connect at least two extending portions located on the same side in the width direction of the main body.

[0033] In some embodiments, the height of the extension portion decreases in a direction away from the main body.

[0034] In the above technical solution, the height of the extension portion is set to decrease in the direction away from the main body, so that the height of the area where the extension portion is away from the main body is smaller. That is to say, the height of the end of the extension portion connected to the main body is relatively large, while the height of the end of the extension portion away from the main body is relatively small, thereby enhancing the connection strength between the extension portion and the main body, 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.

[0035] In some embodiments, the mounting structure is located at the lower edge of the extension portion, the lower edge of the extension portion extends along a horizontal line, and the upper edge of the extension portion tends to decrease in a direction away from the main body. In the above technical solution, it is advantageous for the mounting structures to be located at the same horizontal height, thereby facilitating the mounting operation of the battery.

[0036] In some embodiments, reinforcing ribs are further provided on the extension portion.

For the beam that has been assembled, the battery mounting frame can be installed later, so that the battery mounting frame can be used in a variety of vehicle models.

[0103] 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.

[0104] 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 to improve 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.

[0105] 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.

[0106] In the above technical solution, when the battery is actually installed, when the upper part of the battery is installed from bottom to top, the bottom of the extension part and the stopper of the step surface can be used to remind the battery to be assembled in place, so as to avoid the problem of excessive upward squeezing of the battery and hitting the bottom of the vehicle, thereby protecting the battery. In addition, setting the size of the lower part of the battery larger than the size of the upper part of the battery can further increase the size of the battery to a certain extent, thereby further improving the size energy density of the battery.

[0107] In some embodiments, the battery includes two battery side portions and a battery center portion. In the width direction of the vehicle beam, the two battery side portions are respectively located on both sides of the battery center portion, and the top surface of the battery center portion is lower than the top surface of the battery side portions, so as to form a clearance groove that runs through the length direction of the vehicle beam and has an open top between the two battery side portions and the battery center portion.

[0108] 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.

[0109] 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.

In the description of the embodiments of the present application, the meaning of "multiple" is more than two, unless otherwise clearly and specifically defined.

[0136] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0137] In the description of the embodiments of the present application, the term "and / or" is only a description of the association relationship of associated objects, indicating that three relationships may exist. For example, X and / or Y may represent: X exists alone, X and Y exist at the same time, and Y exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0138] 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).

[0139] In the description of the embodiments of the present application, the orientations or positional relationships indicated by technical terms such as "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" are based on the orientations or positional relationships shown in the accompanying drawings and 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, and therefore should not be understood as a limitation on the embodiments of the present application.

[0140] In the description of the embodiments of the present application, unless otherwise clearly specified and limited, technical terms such as "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0141] Judging from the current market situation, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0142] Some vehicles in the related art have a beam on 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 it is difficult to increase the size of the battery in the width direction of the vehicle, making it difficult to improve the size energy density of the battery; 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 it is difficult to improve the size energy density of the battery, thereby affecting the cruising range of the whole vehicle on a single battery replacement.

[0143] 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 forms an angle with 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.

[0144] When such a battery mounting rack is used to mount the battery on the vehicle beam, since the extension direction of the extension part of the mounting structure is at an angle to the length direction of the vehicle beam, the extension part and the mounting structure thereon will not occupy the space of the battery in the vehicle width direction, which is conducive to increasing the size of the battery in the vehicle width direction and improving the size energy density of the battery. Moreover, since the extension direction of the extension part is at an angle to the length direction of the vehicle beam, setting the mounting structure on the extension part instead of on the vehicle beam can increase the setting space of the mounting structure, which is conducive to flexibly setting the distribution position, quantity and structural form of the mounting structure, meeting the mounting strength requirements of large-size batteries, and is conducive to mounting larger-size batteries, thereby increasing the vehicle's range of a single battery replacement.

[0145] 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.

[0146] The battery disclosed in the embodiments of the present application can be used in an electrical device that uses the battery as a power source or in 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, 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 a fixed or mobile electric toy, for example, a game console, an electric car toy, an electric ship toy, and an electric airplane toy, and the like, and the spacecraft can include an airplane, a rocket, a space shuttle, and a spacecraft, and the like.

[0147] For the convenience of description, the following embodiments are described by taking a vehicle 1000 as an example of an embodiment of the present application.

[0148] Please refer to Figure 1 , Figure 1 A schematic diagram of the structure of a vehicle 1000 provided for some embodiments of the present application. The vehicle 1000 may be a fuel vehicle, a gas vehicle or a new energy vehicle, and the new energy vehicle may 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 may be provided at the bottom, head or tail of the vehicle 1000. The battery 30 may be used to power the vehicle 1000, for example, the battery 30 may be used as an operating power source for the vehicle 1000. The vehicle 1000 may also include a controller 40 and a motor 50, and 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.

[0149] In some embodiments of the present application, the battery 30 can not only serve as an operating power source for the vehicle 1000, but also serve 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.

[0150] Please refer to Figure 2 , Figure 2 The exploded view of the battery 30 provided in some embodiments of the present application. The battery 30 includes a box 301 and a battery cell 302, and the battery cell 302 is accommodated in the box 301. The box 301 is used to provide a storage space for the battery cell 302, and the box 301 can adopt a variety of structures. In some embodiments, refer to Figure 2 The box body 301 may include a first part 3011 and a second part 3012, the first part 3011 and the second part 3012 cover each other, and the first part 3011 and the second part 3012 jointly define a storage space for accommodating the battery cell 302. The second part 3012 may be a hollow structure with an open end, and the first part 3011 may be a plate-like structure, and the first part 3011 covers the open end of the second part 3012, so that the first part 3011 and the second part 3012 jointly define a storage space; the first part 3011 and the second part 3012 may also be hollow structures with an open end on one side, and the open end of the first part 3011 covers the open end of the second part 3012. Of course, the box body 301 formed by the first part 3011 and the second part 3012 may be in various shapes, such as a cylinder, a cuboid, etc.

[0151] The battery 30 may include a battery cell 302. There may be multiple battery cells 302. Multiple battery cells 302 may be connected in series, in parallel, or in a mixed connection. A mixed connection means that multiple battery cells 302 are connected in series and in parallel. Multiple battery cells 302 may be directly connected in series, in parallel, or in a mixed connection, and then the whole formed by multiple battery cells 302 is accommodated in the box 301. Of course, the battery 30 may also be a battery module formed by multiple battery cells 302 connected in series, in parallel, or in a mixed connection, and then multiple battery modules are connected in series, in parallel, or in a mixed connection to form a whole, and accommodated in the box 301. The battery 30 may also include other structures. For example, the battery 30 may also include a busbar for realizing electrical connection between multiple battery cells 302.

[0152] In the present application, the battery cell 302 may include a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery or a magnesium-ion battery, etc., and the embodiments of the present application do not limit this. The battery cell 302 may be cylindrical, flat, rectangular or other shapes, etc., and the embodiments of the present application do not limit this. The battery cell 302 is generally divided into three types according to the packaging method: cylindrical battery cells, square battery cells and soft-pack battery cells, and the embodiments of the present application do not limit this.

[0153] The battery cell 302 includes a housing, an electrode assembly and an electrolyte, and the housing is used to contain the electrode assembly and the electrolyte. The electrode assembly is composed of a positive electrode sheet, a negative electrode sheet and a separator. The battery cell 302 mainly relies on the movement of metal ions between the positive electrode sheet and the negative electrode sheet to work. The material of the separator is not limited, for example, it can be polypropylene or polyethylene.

[0154] The positive electrode sheet can generally include a positive electrode current collector and a positive electrode active material layer, the positive electrode active material layer is directly or indirectly coated on the positive electrode current collector, the positive electrode current collector not coated with the positive electrode active material layer protrudes from the positive electrode current collector coated with the positive electrode active material layer, and the positive electrode current collector not coated with the positive electrode active material layer serves as a positive electrode tab. Taking lithium-ion batteries as an example, the material of the positive electrode current collector can be aluminum, and the material of the positive electrode active material layer can be lithium cobalt oxide, lithium iron phosphate, ternary lithium or lithium manganese oxide, etc.

[0155] The negative electrode sheet may generally include a negative electrode current collector and a negative electrode active material layer, wherein the negative electrode active material layer is directly or indirectly coated on the negative electrode current collector, and 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 a negative electrode tab. The material of the negative electrode current collector may be copper, and the material of the negative electrode active material layer may be carbon or silicon, etc.

[0156] In order to ensure that a large current does not melt, the number of positive electrode tabs is multiple and stacked together, and the number of negative electrode tabs is multiple and stacked together. The electrode assembly can be a winding structure or a laminated structure, and the embodiments of the present application are not limited thereto.

[0157] like Figure 1 As shown, the embodiment of the present application provides a battery mounting rack 10, and the battery mounting rack 10 is used to mount the battery 30 to the vehicle beam 20. Figure 3 and Figure 4 As shown, Figure 3 The schematic diagram of the connection between the battery mounting frame 10, the vehicle beam 20 and the battery 30 is shown. Figure 4 A schematic diagram of the connection between the battery mounting frame 10 and the vehicle beam 20 is shown.

[0158] like Figure 3 and Figure 4 As shown, in some embodiments, the battery mounting frame 10 includes: a main body 1 and an extension 2. The main body 1 is used to connect to the vehicle beam 20 and extend along the length direction of the vehicle beam 20, the length direction of the extension 2 (such as the second direction Y) forms an angle with the extension direction of the main body 1 (such as the first direction X) and extends in a direction away from the main body 1, and a mounting structure 3 is provided on the extension 2, and the mounting structure 3 is used to mount the battery 30.

[0159] 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 chassis-type battery swapping (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: the 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 refer to GB / T 19596 Electric Vehicle Terminology.

[0160] Among them, the vehicle beam 20 is the longitudinal beam or the vehicle bottom beam of the vehicle 1000, and the length direction of the vehicle beam 20 is consistent with the length direction of the vehicle 1000, that is, the front-to-back direction of the vehicle. "The main body 1 extends along the length direction of the vehicle beam 20" means: the extension direction of the main body 1 (such as the first direction X) is consistent with the length direction of the vehicle beam 20, that is, the front-to-back direction of the vehicle 1000; therefore, "the length direction of the extension part 2 (such as the second direction Y) is at an angle to the extension direction of the main body 1 (such as the first direction X)" can be understood as: the extension direction of the extension part 2 intersects with the length direction of the vehicle 1000, for example, it can be an acute angle, a right angle or an obtuse angle.

[0161] 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 at the front side and / or the rear side of the battery 30, and 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 occupying the space on the front side and / or the 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 not occupying 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, for example, it is beneficial to increase the size of the battery 30 in the left and right direction.

[0162] 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 ample space on the front and rear sides of the battery 30 to set the extension portion 2 and the mounting structure 3, it is possible to avoid the extension portion 2 and the mounting structure 3 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.

[0163] 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 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 battery 30 mounted on the mounting structure 3 and improve the mounting reliability of the battery 30, thereby helping to increase the vehicle's range of 1000 single battery replacements.

[0164] Among them, the structure of the mounting structure 3 is not limited, for example, it can include but is not limited to a mounting groove, or a mounting hole, or a mounting protrusion, or a mounting pin, or a mounting screw, etc., which is not limited here.

[0165] 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 set on the beam 20 facing the main body 1.

[0166] 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 .

[0167] In some embodiments, please refer again to Figure 3 and Figure 4 The extension part 2 on at least one side in the width direction (such as the second direction Y) of the main body 1 is configured as a plurality and arranged at intervals along the extension direction (such as the first direction X) of the main body 1, and a battery mounting space 4 is defined between two adjacent extension parts 2 along the extension direction (such as the first direction X) of the main body 1. It is worth noting that the width direction (such as the second direction Y) of the main body 1 is consistent with the width direction of the vehicle beam 20 (such as the direction Y shown in 3), such as the left-right direction of the vehicle 1000.

[0168] That is, at least one side of the main body 1 in the width direction (such as the second direction Y) is provided with a plurality of extension portions 2, and the plurality of extension portions 2 located on the same side of the main body 1 in the width direction (such as the second direction Y) are arranged at intervals along the extension direction (such as the first direction X) of the main body 1. For example, at least one side of the left side and the right side of the main body 1 may be provided with a plurality of extension portions 2 arranged at intervals along the front-to-back direction.

[0169] 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.

[0170] 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.

[0171] In addition, since the extension portion 2 is configured as a plurality 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, thereby further improving the cruising range of the vehicle 1000 on a single battery replacement.

[0172] For example, refer again to Figure 3 and Figure 4 Four extensions 2 are provided on one side of the width of the vehicle beam 20, and 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.

[0173] Of course, the number of extension portions 2 in the above description is only used for illustration. For example, the extension portions 2 on one side of the width of the vehicle beam 20 may also be provided with three, five, or more, etc., which can be set according to the specific needs of the vehicle 1000.

[0174] 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.

[0175] In some embodiments, the battery mounting space 4 is connected along the height direction of the extension portion 2 (such as the third direction Z). Wherein, "the battery mounting space 4 is connected along the height direction of the extension portion 2" means that the battery mounting space 4 is open at both ends in the height direction of the extension portion 2, and there is no structural obstruction on the battery mounting frame 10. Wherein, the height direction of the extension portion 2 can be a direction perpendicular to the thickness direction of the extension portion 2 (such as the first direction X) and the length direction of the extension portion 2 (the second direction Y).

[0176] For example, the height direction of the extension part 2 can be set to be consistent with the height direction of the vehicle 1000, so that when the battery 30 is mounted in the battery mounting space 4, the battery 30 can be made without being blocked by the battery mounting frame 10 on both sides in the height direction of the vehicle 1000, such as the extension part 2, the main body 1 and the mounting structure 3, etc. will 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 improving the size of the battery 30 in the height direction of the vehicle 1000, and is conducive to improving the size energy density of the battery 30, thereby improving the cruising range of the vehicle 1000 for a single battery replacement, and ensuring the height of the battery 30 from the ground, and ensuring the passability of the vehicle 1000. Moreover, it is also conducive to the heat dissipation of the battery 30. Moreover, it is also conducive to reducing the weight of the battery mounting frame 10 and reducing the vehicle-mounted burden of the battery mounting frame 10.

[0177] Some vehicles in the related art usually use a tray to install the battery pack under the vehicle, that is, the battery pack is placed on the tray, and then the tray is installed under the vehicle. When the battery needs to be replaced, the tray is removed, the entire battery pack in the tray is replaced, and then the tray is installed back under the vehicle. However, when replacing the battery, the energy of the battery pack in the tray is usually not completely exhausted, and the replacement of the battery at this time causes energy waste.

[0178] In the embodiment of the present application, the battery mounting rack 10 includes a plurality of battery mounting spaces 4 arranged in sequence along the extension direction of the main body 1 (such as the first direction X), and the battery mounting rack 10 is provided with a mounting structure 3 corresponding to each battery mounting space 4, so that each battery mounting space 4 can be used to mount a battery 30, and the mounting structures 3 corresponding to different battery mounting spaces 4 can be independent of each other, so that each battery mounting space 4 can individually replace the mounted battery 30. Among them, the "correspondence" in the arrangement 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.

[0179] 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 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 beneficial to improving the battery replacement efficiency.

[0180] It can be understood that when the size of the battery 30 is larger, 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 smaller, one battery 30 can be set corresponding to only one battery mounting space 4, or multiple batteries 30 can be set corresponding 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.

[0181] When using such a battery mounting rack 10 to install a battery 30 on a vehicle, since the battery mounting rack 10 includes a plurality of battery mounting spaces 4, and a mounting structure 3 is provided on the battery mounting rack 10 so that each battery mounting space 4 can be used to mount a battery 30, 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 a plurality of 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.

[0182] In some embodiments, please refer to Figure 4-Figure 6 , Figure 5 for Figure 4 A partial enlarged view of the middle A part. Figure 6 for Figure 4 In the front projection view of the connection between the battery mounting frame 10 and the vehicle beam 20, 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.

[0183] In this way, the battery mounting space 4 to which the mounting structure 3 faces corresponds to the battery mounting space 4, and the battery 30 is mounted on the battery mounting space 4 to which the mounting structure 3 faces, so that the corresponding relationship between the mounting structure 3 and the battery mounting space 4 can be clearly defined, and the battery 30 can be connected to the mounting structure 3 facing the battery mounting space 4 by extending the battery 30 into the battery mounting space 4, so that the mounting of the battery 30 can be easily realized. Moreover, when there are multiple battery mounting spaces 4, the mounting structures 3 corresponding to different battery mounting spaces 4 are arranged at different positions and will not interfere with each other, so that the mounting structures 3 corresponding to each battery mounting space 4 can have a relatively sufficient space for flexible arrangement, so that the mounting structure 3 can more easily and reliably mount the battery 30. Therefore, by arranging the mounting structure 3 on the side of the extension portion 2 facing the battery mounting space 4, it is beneficial to reduce the difficulty of arranging the mounting structure 3, and the structural form of the mounting structure 3 can be arranged with a relatively sufficient space for flexible arrangement, so that the mounting structure 3 can more easily and reliably mount the battery 30.

[0184] In some embodiments, please refer again to Figure 4-Figure 6 At least one extension portion 2 located in the middle of the multiple extension portions 2 is a common extension portion 2a, and the common extension portion 2a has battery mounting spaces 4 on both sides 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 on both sides of the common extension portion 2a.

[0185] It is worth noting that "at least one extension part 2 in the middle of the plurality of extension parts 2" refers to: at least one extension part 2 other than the two extension parts 2 on both sides of the plurality of extension parts 2 arranged at intervals along the extension direction (such as the first direction X) of the main body 1. For example, when four extension parts 2 are provided on one side of the width of the beam 20, at least one extension part 2 of the two extension parts 2 in the middle is a common extension part 2a. The common extension part 2a has two mounting surfaces 23 facing the battery mounting spaces 4 on both sides.

[0186] 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.

[0187] 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.

[0188] In some embodiments, please refer again to Figure 4-Figure 6 , the mounting structures 3 on both sides of the common extension part 2a in the extension direction of the main body 1 (such as the first direction X) are misaligned in the orthographic projection on the projection plane perpendicular to the extension direction of the main body 1 (such as the first direction X). That is, the mounting structures 3 on the two mounting installation surfaces 23 of the common extension part 2a are misaligned in the orthographic projection along the extension direction of the main body 1 (such as the first direction X). For example, the distance from any mounting structure 3 on one side of the common extension part 2a to the main body 1 in the length direction of the extension part 2 (such as the second direction Y) is different from the distance from any mounting structure 3 on the other side of the common extension part 2a to the main body 1 in the length direction of the extension part 2 (such as the second direction Y).

[0189] 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 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 reduce 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.

[0190] In some embodiments, please refer again to Figure 4-Figure 6 The battery mounting space 4 is provided with mounting structures 3 on the extension parts 2 on both sides in the extension direction of the main body 1 (such as 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 parts 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.

[0191] 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 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 in the extension part 2, thereby increasing the service life of the common extension part 2a and improving the mounting reliability of the battery 30.

[0192] Further, in some embodiments, the mounting structures 3 on both sides of the battery mounting space 4 in the extension direction (such as the first direction X) of the main body 1 are misaligned in their orthographic projection on a projection plane perpendicular to the extension direction (such as 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 (such as the second direction Y) of the extension part 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 (such as the second direction Y) of the extension part 2.

[0193] Therefore, by setting the mounting structures 3 on both sides of the battery mounting space 4 to be offset 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 deformation, fracture and other problems of the extension part 2 caused by stress concentration.

[0194] 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 as the same structure, which is beneficial to reducing costs and reducing production processes.

[0195] 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.

[0196] In some embodiments, please refer to Figure 4 and Figure 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 arranged at intervals along the length direction (such as the second direction Y) of the extension portion 2.

[0197] 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.

[0198] In some embodiments, please refer to Figure 5 The extension portion 2 includes a mounting edge 24 protruding 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 inside of the battery mounting space 4 along the extension direction of the main body 1 (such as the first direction X).

[0199] 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.

[0200] In some embodiments, please refer to Figure 4 and Figure 5 , the mounting edge 24 is located at the lower edge of the extension portion 2 in the height direction (such as the third direction Z). Here, the two ends of the extension portion 2 in the height direction (such as the third direction Z) are defined as the upper and lower ends. When the height direction of the extension portion 2 is consistent with the height direction of the vehicle 1000, the two ends of the extension portion 2 in the height direction are also the upper and lower ends in the gravity direction.

[0201] As a result, the mounting structure 3 is set at a lower height, which is conducive to reducing the difficulty of maintenance of the mounting structure 3, and is beneficial to the loading connection between the mounting structure 3 and the battery 30, and improves the compactness of the 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.

[0202] 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 portion 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 portion 2. There is no need to increase the gap between the battery 30 and the extension portion 2 to meet the tool insertion requirement, thereby reducing space waste 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.

[0203] In some embodiments, please refer to Figure 4 and Figure 5The 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 are arranged at intervals along the length direction of the mounting edge 24 .

[0204] Therefore, since 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), 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, and multiple mounting structures 3 are set along the length direction of the mounting edge 24. The intervals, thereby facilitating the mounting stability of the battery 30, or facilitating increasing the number of batteries 30 mounted on the mounting edge 24.

[0205] In some embodiments, please refer to Figure 7 , Figure 7 This is a partially enlarged view of a battery mounting rack 10 according to another embodiment of the present application. The length direction of the mounting edge 24 is the same as the length direction of the extension 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.

[0206] 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.

[0207] In some embodiments, an extension portion 2 is arranged on one side of the width direction (such as the second direction Y) of the main body 1. It is worth noting that the width direction (such as the second direction Y) of the main body 1 is consistent with the width direction of the vehicle beam 20, and the width direction of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, such as the left and right direction of the vehicle 1000. For example, the extension portion 2 is arranged on the left side of the main body 1, or the extension portion 2 is arranged on the right side of the main body 1.

[0208] 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 to the main body 1 by the extension portion 2 mounted with the battery 30 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.

[0209] 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 extension portions 2 are respectively 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 the left and right sides of the vehicle beam 20 can have extension portions 2.

[0210] In some embodiments, please refer to Figure 3 and Figure 4 , an extension portion 2 is arranged on each of the two sides in the width direction (such as the second direction Y) of the main body 1. That is to say, a plurality of extension portions 2 are provided on the main body 1, and at least two of the plurality of extension portions 2 are respectively located on the two sides in the width direction (such as the second direction Y) of the main body 1. It is worth noting that the width direction (such as the second direction Y) of the main body 1 is consistent with the width direction of the vehicle beam 20, and the width direction of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, such as the left and right direction of the vehicle 1000. For example, an extension portion 2 is provided on the left side of the main body 1, and an extension portion 2 is also provided on the right side of the main body 1.

[0211] Therefore, by arranging extension portions 2 on both sides of the width direction of the main body 1 (such as the second direction Y), 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.

[0212] In some embodiments, please refer to Figure 3 and Figure 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. 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.

[0213] It is worth noting that the width direction of the main body 1 (such as the second direction Y) is consistent with the width direction of the vehicle beam 20, such as the left-right direction of the vehicle 1000. For example, the first extension 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 along a direction inclined to the width direction of the vehicle beam 20, and the inclination angles are the same.

[0214] Therefore, by setting the extension directions of the first extension portion 21 and the second extension portion 22 to be the same, and the projections of the first extension portion 21 and the second extension portion 22 along the extension direction of the first extension portion 21 overlap, the first extension portion 21 and the second extension portion 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.

[0215] In some embodiments, please refer to Figure 3 and Figure 4 , when at least one side in the width direction (such as the second direction Y) of the main body 1 is provided with a plurality of extensions 2 spaced apart along the extension direction (such as the first direction X) of the main body 1, the battery mounting frame 10 further includes a reinforcing portion 5, and the reinforcing portion 5 is used to connect at least two extensions 2 located on the same side in the width direction (such as the second direction Y) of the main body 1. It is worth noting that this embodiment is applicable to the cases of "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.

[0216] In addition, it is worth noting that the width direction of the main body 1 (such as the second direction Y) is consistent with the width direction of the vehicle beam 20, such as the left-right direction of the vehicle 1000. For example, 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.

[0217] This helps to enhance the overall structural strength of the battery mounting frame 10 , reduce deformation of the extension portion 2 caused by force, and improve the mounting reliability of the battery 30 .

[0218] In some embodiments, the reinforcement portion 5 and the main body 1 are disposed on both sides of the length direction (such as the second direction Y) of the extension portion 2. Thus, the two extension portions 2 defining the battery mounting space 4 can be connected at both ends in the length direction (such as the second direction Y) of the extension portion 2 through the main body 1 and the reinforcement portion 5, respectively. In this way, the structure around the battery mounting space 4 is formed into a ring shape, which has a higher structural strength, a higher mounting reliability for the battery 30, and can protect the battery 30 more comprehensively from the surrounding side, and the position of the mounting structure 3 can be flexibly selected.

[0219] In some embodiments, please refer to Figure 5 The height of the extension portion 2 (i.e., the dimension in the height direction (such as the third direction Z) of the extension portion 2) tends to decrease along the direction away from the main body portion 1. It is worth noting that "tends to decrease" can be a gradual decrease or a stepwise decrease.

[0220] Therefore, by setting the height of the extension part 2 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.

[0221] When the mounting structure 3 is located at the lower edge of the extension part 2, for example, it is arranged on the mounting edge 24, and the mounting edge 24 is located at the lower edge of the extension part 2, the lower edge of the extension part 2 can be set to extend horizontally, and the upper edge of the extension part 2 has a decreasing trend along the direction away from the main body 1. It is worth noting that "decreasing trend" can be a gradual decrease or a stepwise decrease. Therefore, it is beneficial for the mounting structures 3 to be located at the same level, thereby facilitating the mounting operation of the battery 30.

[0222] In some embodiments, in combination Figure 7 As shown, the extension part 2 is also provided with a reinforcing rib 25. The structural form of the reinforcing rib 25 is not limited, for example, it can be a straight line, a curve, or a cross shape, etc. Therefore, by providing the reinforcing rib 25, the structural strength of the extension part 2 is enhanced, and the problem of deformation of the extension part 2 under stress is improved.

[0223] Exemplarily, 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 in 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 improve the structural strength of the extension portion 2 and improve the reliability of the extension portion 2 for mounting the battery 30 while reducing the number of reinforcing ribs 25.

[0224] For example, 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 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 portion 2 (such as the third direction Z) corresponding to the mounting structure 3. This can improve the structural strength of the extension portion 2 while reducing the number of reinforcing ribs 25, thereby improving the reliability of the extension portion 2 for mounting the battery 30.

[0225] Exemplarily, when a plurality of mounting structures 3 are provided on the extension portion 2, at least part of the reinforcing ribs 25 are arranged between two adjacent mounting structures 3 along the height direction (such as the third direction Z) of the extension portion 2. When the battery 30 is mounted on the mounting structure 3 of the extension portion 2, the position of the mounting structure 3 of the extension portion 2 is subjected to concentrated force and is easily deformed and damaged. When at least part of the reinforcing ribs 25 are arranged 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 fracture caused by stress concentration between the two adjacent mounting structures 3 can be improved, and the mounting reliability of the extension portion 2 for the battery 30 can be improved.

[0226] In some embodiments, please refer to Figure 5 The extension portion 2 is provided with a first weight-reducing structure 26. For example, the first weight-reducing structure 26 may include but is not limited to a weight-reducing hole, a weight-reducing groove, or a thinning treatment.

[0227] 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 .

[0228] In some embodiments, please refer to Figure 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 the extension direction (such as the first direction X).

[0229] Therefore, by providing the beam avoidance groove 13, and the beam avoidance groove 13 has an opening that passes through the extension direction of the main body 1 (such as the first direction X), it is convenient to accommodate at least part of the beam 20 through the beam avoidance groove 13, and the opening can avoid the beam 20, so as to avoid the interference between the battery mounting frame 10 and the beam 20, thereby reducing the difficulty of loading and unloading the battery mounting frame 10, improving the compactness of the matching between the main body 1 and the beam 20, and making full use of the space near the beam 20 to set the battery 30, which is conducive to increasing the size of the battery 30.

[0230] 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.

[0231] In some embodiments, please refer to Figure 4The 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). 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 beam avoidance groove 13 with an open top between the first main body wall 11 and the two second main body walls 12.

[0232] It is worth noting that the width direction of the main body 1 (such as the second direction Y) is consistent with the width direction of the vehicle beam 20, such as the left-right direction of the vehicle 1000. "The first main body wall 11 is arranged along the width direction of the main body 1 (such as the second direction Y)" means: the length direction of the first main body wall 11 is consistent with the width direction of the main body 1 (such as the second direction Y). "The second main body walls 12 are arranged along the extension direction of the main body 1 (such as the first direction X)" means: the length direction of the second main body wall 12 is consistent with the extension direction of the main body 1 (such as the first direction X).

[0233] Thus, the beam avoidance groove 13 can be defined by the first main body wall 11 and the two second main body walls 12, so as to reduce the difficulty of forming the beam avoidance groove 13, and the two second main body walls 12 are respectively connected to the two ends of the first main body wall 11 in the width direction, so as to define an opening that passes through along the length direction of the main body 1. In addition, since the top of the beam avoidance groove 13 is open, the main body 1 can be pushed upward from bottom to top, so that the beam 20 enters the beam avoidance groove 13, which is conducive to reducing the difficulty of assembling the battery mounting frame 10 to the beam 20. For the beam 20 that has been assembled, the battery mounting frame 10 can be installed later, so that the battery mounting frame 10 can be used for a variety of vehicle models. The present application is not limited to this. For example, in other embodiments of the present application, the beam avoidance groove 13 can also be set to be open at the bottom. At this time, the battery mounting frame 10 and the beam 20 can be assembled simultaneously during the process of assembling the beam 20.

[0234] For example, in combination 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 cooperation between the main body 1 and the vehicle beam 20 and reducing space waste.

[0235] Exemplarily, 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 means of fasteners such as screws, so as to meet the requirement of installing the main body 1 on the vehicle beam 20 .

[0236] In some embodiments, please refer to Figure 5 , the extension part 2 is connected to the second main body wall 12. In this way, the difficulty of connecting the extension part 2 with the main body 1 can be reduced, and the second main body walls 12 on both sides can be used to connect the extension part 2, so that the extension part 2 can be located on both sides of the width direction of the vehicle beam 20, so that the battery 30 can be arranged in the width direction of the vehicle beam 20, so as to increase the size of the battery 30 or increase the number of the battery 30.

[0237] In some embodiments, please refer to Figure 8 The first main body wall 11 and / or the second main body wall 12 is provided with a second weight reduction structure 14. For example, the second weight reduction structure 14 may include but is not limited to a weight reduction hole, a weight reduction groove, or a thinning treatment.

[0238] Therefore, a second weight reduction structure 14 can be set on the first main wall 11 and / or a second weight reduction 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.

[0239] In some embodiments, please refer to Figure 8 , 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, or only on the mounting structure 3 on the first main body wall 11, or can be mounted on both the mounting structure 3 on the extension portion 2 and the mounting structure 3 on the first main body wall 11.

[0240] Therefore, by setting the mounting structure 3 on the first main wall 11, the installation space at the first main 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.

[0241] In some embodiments, the first main body wall 11 and the two second main body walls 12 are integrally formed. In this way, the first main body wall 11 and the two second main body walls 12 can be constructed as an integrally formed structure, which is conducive to reducing production processes and thus reducing production costs. Of course, it is not limited to this, and the first main body wall 11 and the second main body wall 12 can also be set as a split structure and assembled and connected, and the structural reliability is improved.

[0242] In some embodiments, the main body 1 and the extension 2 are integrally formed. In this way, the main body 1 and the extension 2 can be constructed as an integrally formed structure, which is conducive to reducing the production process and thus reducing the production cost. Of course, it is not limited to this, and the main body 1 and the extension 2 can also be set as a separate structure and assembled and connected, and the structural reliability is improved.

[0243] Second, please refer to Figure 4The present application provides a vehicle frame assembly 100 , which includes a vehicle beam 20 and a battery mounting bracket 10 as in any of the above embodiments, wherein the battery mounting bracket 10 is used to mount a battery 30 to the vehicle beam 20 .

[0244] Therefore, when the battery 30 is installed on the vehicle beam 20 through the battery mounting frame 10, the mounting space of the battery 30 can be expanded, so as to facilitate mounting a larger battery 30 on the battery mounting frame 10, thereby improving the cruising range of the vehicle 1000 after a single battery replacement.

[0245] In the third aspect, the present application provides a frame assembly of another embodiment, the frame assembly comprising: a vehicle beam 20 and an extension portion 2. It is worth noting that, compared with the frame assembly 100 of the second aspect of the present application, the frame assembly of the third embodiment may not include a main body 1 for connecting to the vehicle beam 20, or may include a main body 1 for connecting to the vehicle beam 20, but the shape of the main body 1 is not limited, such as the main body 1 may extend along the length direction (such as the first direction X) of the vehicle beam 20, or the main body 1 may not extend along the length direction (such as the first direction X) of the vehicle beam 20, and the shape of the main body 1 can be flexibly designed according to actual needs.

[0246] In some embodiments, Figure 3 and Figure 4 As shown, at least part of the extension portion 2 is located on one side of the width direction (such as the second direction Y) of the vehicle beam 20, the part of the extension portion 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 and extends in a direction away from the vehicle beam 20, and a mounting structure 3 is provided on the part of the extension portion 2 located on one side of 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.

[0247] 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 portion 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 portion 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.

[0248] 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 at the front side and / or the rear side of the battery 30, and 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 occupying the space on the front side and / or the 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 not occupying 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, for example, it is beneficial to increase the size of the battery 30 in the left and right direction.

[0249] 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 ample space on the front and rear sides of the battery 30 to set the extension portion 2 and the mounting structure 3, it is possible to avoid the extension portion 2 and the mounting structure 3 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.

[0250] Moreover, compared with the solution of setting the mounting structure on the two 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 battery 30 mounted on the mounting structure 3 and improve the mounting reliability of the battery 30, thereby helping to increase the vehicle's range of 1000 single battery replacements.

[0251] Among them, the structure of the mounting structure 3 is not limited, for example, it can include but is not limited to a mounting groove, or a mounting hole, or a mounting protrusion, or a mounting pin, or a mounting screw, etc., which is not limited here.

[0252] In some embodiments, please refer again to Figure 3 and Figure 4 The extension portion 2 on at least one side in the width direction (such as the second direction Y) of the vehicle beam 20 is configured as a plurality and is arranged at intervals along the length direction (such as the first direction X) of the vehicle beam 20, and a battery mounting space 4 is defined between two adjacent extension portions 2 along the length direction (such as the first direction X) of the vehicle beam 20.

[0253] That is, at least one side of the vehicle beam 20 in the width direction (such as the second direction Y) is provided with a plurality of extensions 2, and the plurality of extensions 2 on the same side in the width direction (such as the second direction Y) of the vehicle beam 20 are arranged at intervals along the length direction (such as the first direction X) of the vehicle beam 20. It is worth noting that the width direction (such as the second direction Y) of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. Therefore, at least one side of the left and right sides of the vehicle beam 20 may be provided with a plurality of extensions 2 arranged at intervals along the front-rear direction.

[0254] 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.

[0255] 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.

[0256] In addition, since the extension part 2 is configured as a plurality 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, thereby further improving the cruising range of the vehicle 1000 on a single battery replacement.

[0257] For example, refer again to Figure 3 and Figure 4 Four extensions 2 are provided on one side of the width of the vehicle beam 20, and 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.

[0258] Of course, the number of extension portions 2 in the above description is only used for illustration. For example, the extension portions 2 on one side of the width of the vehicle beam 20 may also be provided with three, five, or more, etc., which can be set according to the specific needs of the vehicle 1000.

[0259] 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.

[0260] In some embodiments, the battery mounting space 4 is connected along the height direction of the vehicle beam 20 (such as the third direction Z). Herein, "the battery mounting space 4 is connected along the height direction of the vehicle beam 20" means that the battery mounting space 4 is open at both ends in the height direction of the vehicle beam 20 and is not blocked by the structure on the battery mounting frame 10. Herein, the height direction of the vehicle beam 20 is consistent with the height direction of the vehicle 1000.

[0261] 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 will 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 improving the size of the battery 30 in the height direction of the vehicle 1000, and is conducive to improving the size energy density of the battery 30, thereby improving the cruising range of the vehicle 1000 for a single battery replacement, and ensuring the height of the battery 30 from the ground, and ensuring the passability of the vehicle 1000. Moreover, it is also conducive to the heat dissipation of the battery 30. Moreover, 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.

[0262] Some vehicles in the related art usually use a tray to install the battery pack under the vehicle, that is, the battery pack is placed on the tray, and then the tray is installed under the vehicle. When the battery needs to be replaced, the tray is removed, the entire battery pack in the tray is replaced, and then the tray is installed back under the vehicle. However, when replacing the battery, the energy of the battery pack in the tray is usually not completely exhausted, and the replacement of the battery at this time causes energy waste.

[0263] In an embodiment of the present application, the battery mounting frame 10 includes a plurality of battery mounting spaces 4 arranged in sequence along the length direction of the vehicle beam 20 (such as the first direction X), and the battery mounting frame 10 includes a plurality of battery mounting spaces 4, and the battery mounting frame 10 is provided with a mounting structure 3 corresponding to each battery mounting space 4, so that each battery mounting space 4 can be used to mount a battery 30, and the mounting structures 3 corresponding to different battery mounting spaces 4 can be independent of each other, so that each battery mounting space 4 can individually replace the mounted battery 30. 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.

[0264] 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 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 beneficial to improving the battery replacement efficiency.

[0265] It can be understood that when the size of the battery 30 is larger, 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 smaller, one battery 30 can be set corresponding to only one battery mounting space 4, or multiple batteries 30 can be set corresponding 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.

[0266] When using such a battery mounting rack 10 to install a battery 30 on a vehicle, since the battery mounting rack 10 includes a plurality of battery mounting spaces 4, and a mounting structure 3 is provided on the battery mounting rack 10 so that each battery mounting space 4 can be used to mount a battery 30, 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 a plurality of 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.

[0267] In some embodiments, please refer to Figure 4-Figure 6 , Figure 5 for Figure 4 A partial enlarged view of the middle A part. Figure 6 for Figure 4 In the front projection view of the connection between the battery mounting frame 10 and the vehicle beam 20, 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.

[0268] In this way, the battery mounting space 4 to which the mounting structure 3 faces corresponds to the battery mounting space 4, and the battery 30 is mounted on the battery mounting space 4 to which the mounting structure 3 faces, so that the corresponding relationship between the mounting structure 3 and the battery mounting space 4 can be clearly defined, and the battery 30 can be connected to the mounting structure 3 facing the battery mounting space 4 by extending the battery 30 into the battery mounting space 4, so that the mounting of the battery 30 can be easily realized. Moreover, when there are multiple battery mounting spaces 4, the mounting structures 3 corresponding to different battery mounting spaces 4 are arranged at different positions and will not interfere with each other, so that the mounting structures 3 corresponding to each battery mounting space 4 can have a relatively sufficient space for flexible arrangement, so that the mounting structure 3 can more easily and reliably mount the battery 30. Therefore, by arranging the mounting structure 3 on the side of the extension portion 2 facing the battery mounting space 4, it is beneficial to reduce the difficulty of arranging the mounting structure 3, and the structural form of the mounting structure 3 can be arranged with a relatively sufficient space for flexible arrangement, so that the mounting structure 3 can more easily and reliably mount the battery 30.

[0269] In some embodiments, please refer again to Figure 4-Figure 6 At least one extension portion 2 located in the middle of the multiple extension portions 2 is a common extension portion 2a, and the common extension portion 2a has battery mounting spaces 4 on both sides 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.

[0270] It is worth noting that "at least one extension part 2 in the middle of the plurality of extension parts 2" refers to: the remaining at least one extension part 2 except the two extension parts 2 on both sides of the plurality of extension parts 2 arranged at intervals along the length direction (such as the first direction X) of the vehicle beam 20. For example, when four extension parts 2 are provided on one side of the width of the vehicle beam 20, at least one extension part 2 of the two extension parts 2 in the middle is a common extension part 2a. The common extension part 2a has two mounting surfaces 23 facing the battery mounting spaces 4 on both sides.

[0271] 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 arranged 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.

[0272] 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 length direction (such as the first direction X) of the vehicle beam 20. In this way, each extension portion 2 may be arranged with a mounting structure 3 corresponding to only one side of the battery mounting space 4, thereby reducing the bearing force of each extension portion 2 on the battery and improving the mounting reliability of the battery 30.

[0273] In some embodiments, please refer again to Figure 4-Figure 6 , the mounting structures 3 on both sides of the common extension part 2a in the length direction (such as the first direction X) of the vehicle beam 20 are misaligned in the projection plane perpendicular to the length direction (such as the first direction X) of the vehicle beam 20. That is, the mounting structures 3 on the two mounting installation surfaces 23 of the common extension part 2a are misaligned in the length direction (such as the first direction X) of the vehicle beam 20. For example, the distance from any mounting structure 3 on one side of the common extension part 2a to the vehicle beam 20 in the width direction (such as the second direction Y) of the vehicle beam 20 is different from the distance from any mounting structure 3 on the other side of the common extension part 2a to the vehicle beam 20 in the width direction (such as the second direction Y) of the vehicle beam 20.

[0274] 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 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 reduce 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.

[0275] In some embodiments, please refer again to Figure 4-Figure 6 The battery mounting space 4 is provided with mounting structures 3 on the extensions 2 on both sides in the length direction (such as 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.

[0276] 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 in the extension part 2, thereby increasing the service life of the common extension part 2a, thereby improving the mounting reliability of the battery 30.

[0277] Further, in some embodiments, the mounting structures 3 on both sides of the battery mounting space 4 in the length direction (such as the first direction X) of the vehicle beam 20 are misaligned in the projection plane perpendicular to the length direction (such as the first direction X) of the vehicle beam 20. For example, the distance from any mounting structure 3 on one side of the battery mounting space 4 to the vehicle beam 20 in the width direction (such as the second direction Y) of the vehicle beam 20 is different from the distance from any mounting structure 3 on the other side of the battery mounting space 4 to the vehicle beam 20 in the width direction (such as the second direction Y) of the vehicle beam 20.

[0278] Therefore, by setting the mounting structures 3 on both sides of the battery mounting space 4 to be offset 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 deformation, fracture and other problems of the extension part 2 caused by stress concentration.

[0279] In addition, when the mounting structures 3 on both sides of the common extension portion 2a in the length 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 length 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 length 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 length direction of the vehicle beam 20 (such as the first direction X), multiple extension portions 2 can be constructed as the same structure, which is beneficial to reducing costs and reducing production processes.

[0280] 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 length 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 length 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 length direction of the vehicle beam 20 (such as the first direction X) on the projection plane perpendicular to the length direction of the vehicle beam 20 (such as the first direction X) can also coincide, thereby simplifying processing and reducing costs.

[0281] In some embodiments, please refer to Figure 4 and Figure 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 arranged at intervals along the width direction (such as the second direction Y) of the vehicle beam 20.

[0282] In this way, it is beneficial to make full use of the space in the width direction (such as the second direction Y) of the vehicle beam 20 and arrange a larger number of mounting structures 3, thereby helping to enhance the mounting stability of the battery 30, or helping to increase the number of batteries 30 mounted in the battery mounting space 4.

[0283] In some embodiments, please refer to Figure 5 The extension portion 2 includes a mounting edge 24 protruding 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 inside of the battery mounting space 4 along the length direction of the vehicle beam 20 (such as the first direction X).

[0284] 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.

[0285] In some embodiments, please refer to Figure 4 and Figure 5 The mounting edge 24 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). The height direction of the vehicle beam 20 (such as the third direction Z) is consistent with the height direction of the vehicle 1000, that is, the gravity direction.

[0286] As a result, the mounting structure 3 is set at a lower height, which is conducive to reducing the difficulty of maintenance of the mounting structure 3, and is beneficial to the loading connection between the mounting structure 3 and the battery 30, and improves the compactness of the 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.

[0287] 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 portion 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 portion 2. There is no need to increase the gap between the battery 30 and the extension portion 2 to meet the tool insertion requirement, thereby reducing space waste 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.

[0288] In some embodiments, please refer to Figure 4 and Figure 5 The length direction of the mounting edge 24 is the same as the width direction (such as the second direction Y) of the vehicle beam 20 , and a plurality of mounting structures 3 arranged at intervals along the length direction of the mounting edge 24 are provided on the mounting edge 24 .

[0289] 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, and multiple mounting structures 3 are set along the length direction of the mounting edge 24. The interval, which is beneficial to enhance the mounting stability of the battery 30, or helps to increase the number of batteries 30 mounted on the mounting edge 24.

[0290] In some embodiments, please refer to Figure 7 , Figure 7 This is a partially enlarged view of a battery mounting frame 10 according to another embodiment of the present application. The length direction of the mounting edge 24 is the same as the width direction (such as the second direction Y) of the vehicle beam 20, and the mounting structure 3 on the mounting edge 24 is configured as one and extends along the length direction of the mounting edge 24.

[0291] 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.

[0292] In some embodiments, an extension portion 2 is disposed on one side of the beam 20 in the width direction (such as the second direction Y). It is worth noting that the width direction (such as the second direction Y) of the beam 20 is consistent with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. For example, the extension portion 2 is disposed on the left side of the beam 20, or the extension portion 2 is disposed on the right side of the beam 20.

[0293] Therefore, by arranging the extension part 2 only on one side of the width direction of the vehicle beam 20 (such as the second direction Y), the force transmitted to the vehicle beam 20 by the extension part 2 mounted with the battery 30 can be reduced, thereby improving the connection reliability between the extension part 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.

[0294] In some embodiments, please refer to Figure 3 and Figure 4, an extension portion 2 is arranged on each of the two sides in the width direction (such as the second direction Y) of the vehicle beam 20. That is to say, a plurality of extension portions 2 are provided on the vehicle beam 20, and at least two of the plurality of extension portions 2 are respectively located on the two sides in the width direction (such as the second direction Y) of the vehicle beam 20. It is worth noting that the width direction (such as the second direction Y) of the vehicle beam 20 is consistent with the width direction of the vehicle 1000, such as the left-right direction of the vehicle 1000. For example, an extension portion 2 is provided on the left side of the vehicle beam 20, and an extension portion 2 is also provided on the right side of the vehicle beam 20.

[0295] Therefore, by arranging the extension parts 2 on both sides of the beam 20 in the width direction (such as the second direction Y), the extension parts 2 on both sides of the 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 beam 20 can be mounted respectively, or the two batteries 30 located on both sides in the width direction of the beam 20 can be mounted respectively, thereby increasing the mounting strength of the battery 30 or increasing the number of mounted batteries 30.

[0296] In some embodiments, please refer to Figure 3 and Figure 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.

[0297] It is worth noting that the width direction of the beam 20 (such as 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 (such as the second direction Y), or the first extension portion 21 and the second extension portion 22 both extend along a direction inclined to the width direction of the beam 20, and the inclination angles are the same.

[0298] Therefore, by setting the extension directions of the first extension portion 21 and the second extension portion 22 to be the same, and the projections of the first extension portion 21 and the second extension portion 22 along the extension direction of the first extension portion 21 overlap, the first extension portion 21 and the second extension portion 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.

[0299] In some embodiments, please refer to Figure 3 and Figure 4, when at least one side in the width direction (such as the second direction Y) of the beam 20 is provided with a plurality of extensions 2 arranged at intervals along the length direction (such as the first direction X) of the beam 20, the battery mounting frame 10 further includes a reinforcing portion 5, which is used to connect at least two extensions 2 located on the same side in the width direction (such as the second direction Y) of the beam 20. It is worth noting that this embodiment is applicable to the cases of "at least one extension 2 is arranged on each of the two sides in the width direction of the beam 20" and "an extension 2 is arranged on one side in the width direction of the beam 20". In addition, the at least two extensions 2 connected by the reinforcing portion 5 may be adjacent or non-adjacent.

[0300] In addition, it is worth noting that the width direction of the beam 20 (such as 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.

[0301] This helps to enhance the overall structural strength of the battery mounting frame 10 , reduce deformation of the extension portion 2 caused by force, and improve the mounting reliability of the battery 30 .

[0302] In some embodiments, the reinforcement part 5 and the main body 1 are disposed on both sides of the extension part 2 in the width direction (such as the second direction Y) of the vehicle beam 20. Thus, the two ends of the two extension parts 2 defining the battery mounting space 4 in the width direction (such as the second direction Y) of the vehicle beam 20 can be connected by the main body 1 and the reinforcement part 5 respectively. In this way, the structure around the battery mounting space 4 is formed into a ring shape, which has a higher structural strength, a higher mounting reliability for the battery 30, and can protect the battery 30 more comprehensively from the surrounding side, and the position of the mounting structure 3 can be flexibly selected.

[0303] In some embodiments, please refer to Figure 5 The height of the extension part 2 in the height direction of the vehicle beam 20 (such as the third direction Z) tends to decrease along the direction away from the vehicle beam 20. It is worth noting that "tends to decrease" can be a gradual decrease or a step-wise decrease.

[0304] 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.

[0305] When the mounting structure 3 is located at the lower edge of the extension part 2 in the height direction of the vehicle beam 20 (such as the third direction Z), for example, it is arranged on the mounting edge 24, and the mounting edge 24 is located at the lower edge of the extension part 2, the lower edge of the extension part 2 can be set to extend horizontally, and the upper edge of the extension part 2 in the height direction of the vehicle beam 20 (such as the third direction Z) shows a decreasing trend in the direction away from the vehicle beam 20. It is worth noting that "showing a decreasing trend" can be a gradual decrease or a stepwise decrease. Therefore, it is beneficial for the mounting structures 3 to be located at the same level, thereby facilitating the mounting operation of the battery 30.

[0306] In some embodiments, in combination Figure 7 As shown, the extension part 2 is also provided with a reinforcing rib 25. The structural form of the reinforcing rib 25 is not limited, for example, it can be a straight line, a curve, or a cross shape, etc. Therefore, by providing the reinforcing rib 25, the structural strength of the extension part 2 is enhanced, and the problem of deformation of the extension part 2 under stress is improved.

[0307] Exemplarily, 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 near the middle of the extension portion 2 in the width direction of the vehicle beam 20 (such as the second direction Y), that is, in the center or approximately in the center as a whole, for example, in the position range between 1 / 3-2 / 3 of the extension portion 2 in the width direction of the vehicle beam 20 (such as the second direction Y). This can improve the structural strength of the extension portion 2 and the reliability of the extension portion 2 for mounting the battery 30 while reducing the number of reinforcing ribs 25.

[0308] For example, when a battery 30 is mounted on the mounting structure 3 of the extension part 2, 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, thereby reducing the number of reinforcing ribs 25 while better improving the effect on the structural strength of the extension part 2 and improving the reliability of the extension part 2 for mounting the battery 30.

[0309] Exemplarily, when a plurality of mounting structures 3 are provided on the extension part 2, at least part of the reinforcing ribs 25 are arranged between two adjacent mounting structures 3 along the height direction (such as the third direction Z) Z of the vehicle beam 20. 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 easily deformed and damaged. When at least part of the reinforcing ribs 25 are arranged between two adjacent mounting structures 3, the structural strength of the extension part 2 between the two adjacent mounting structures 3 can be enhanced, the problem of fracture caused by stress concentration between the two adjacent mounting structures 3 can be improved, and the mounting reliability of the extension part 2 for the battery 30 can be improved.

[0310] In some embodiments, please refer to Figure 5 The extension portion 2 is provided with a first weight-reducing structure 26. For example, the first weight-reducing structure 26 may include but is not limited to a weight-reducing hole, a weight-reducing groove, or a thinning treatment.

[0311] 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 .

[0312] In some embodiments, the extension portion 2 is entirely located on one side of the beam 20 in the width direction (such as the second direction Y), and the frame assembly 100 further includes: a main body 1 connected to the beam 20 , and the extension portion 2 is connected to the main body 1 .

[0313] Thus, by setting the main body 1, the extension part 2 can be connected to the vehicle beam 20 through the main body 1, so as to reduce the difficulty of setting the extension part 2, and the extension part 2 is set on one side of the width direction (such as the second direction Y) of the vehicle beam 20, so that the space in the width direction of the vehicle beam 20 can be fully utilized to mount the battery 30, thereby facilitating the increase of the size of the battery 30. In addition, when multiple extension parts 2 are set, for example, multiple extension parts 2 can be set on the main body 1 first, and then the main body 1 can be connected to the vehicle beam 20, so that it is convenient to simplify the assembly steps to reduce the difficulty of assembly, and when the extension part 2 is set on the vehicle beam 20 of different sizes, it is only necessary to adjust the main body 1, so as to enhance the adaptability of the extension part 2.

[0314] The main body 1 and the extension 2 can be integrally formed to simplify the production steps and reduce the production cost. Alternatively, the main body 1 and the extension 2 can be separately formed and assembled together, such as by welding or screwing, so as to reduce the difficulty of processing each part.

[0315] In some embodiments, the main body 1 spans the vehicle beam 20, so that the main body 1 is connected to the extension part 2 on both sides of the vehicle beam 20 in the width direction (such as 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.

[0316] Therefore, by setting the main body 1 across the beam 20, the main body 1 can simultaneously connect 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. It is also beneficial 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 battery 30, the space on both sides of the width of the beam 20 can be fully utilized to mount the battery 30, which is beneficial to increase the size and number of the battery 30, thereby improving the cruising range of the vehicle 1000 in a single battery replacement.

[0317] In a fourth aspect, the present application provides a vehicle 1000, comprising a battery 30 and a frame assembly 100 as in any of the above embodiments, wherein the battery 30 is mounted to the frame assembly 100. Thus, since the frame assembly 100 in the embodiment of the present application is provided, the size and number of the battery 30 can be increased, thereby facilitating the improvement of the cruising range of the vehicle 1000 after a single battery replacement.

[0318] In some embodiments, please refer to Fig. 9 and Fig.10 The battery 30 includes an upper battery portion 30a and a lower battery portion 30b, wherein the upper battery portion 30a is higher than the bottom surface of the vehicle beam 20, and 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 horizontal space on both sides of the width of the vehicle beam 20, thereby improving the space utilization rate, so that the size of the battery 30 in the height direction of the vehicle 1000 can be increased to improve the energy density of the battery 30. At the same time, the mounting structure 30c is detachably connected to the mounting structure 3, which is convenient for reducing the difficulty of replacing the battery 30, thereby improving the efficiency of battery replacement.

[0319] Further, in some embodiments, please refer to Fig. 9 and Fig.10 , the extension part 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 part 2, and the battery 30 is provided with a mounting structure 30c at a position between the upper battery part 30a and the lower battery part 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 battery part 30a can extend into the battery mounting space 4, and the lower battery part 30b is located below the battery mounting space 4. The extension part 2 can be used to play a certain protective role on the upper battery part 30a, so as to reduce the risk of damage to the battery 30 and help extend 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. Moreover, the mounting structure 30c is arranged at a position between the upper battery part 30a and the lower battery part 30b, 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 conducive to the battery replacement operation.

[0320] 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.

[0321] In some embodiments, please refer to Fig. 9 and Fig.10In the length direction of the vehicle beam 20 (such as the first direction X), the size of the upper battery portion 30a is smaller than the size of the lower battery portion 30b, so as to form a step surface 30d between the upper battery portion 30a and the lower battery portion 30b, and the step surface 30d stops at the bottom of the extension portion 2.

[0322] It is worth noting that the step surface 30d stops at the bottom of the extension part 2 in a broad sense, that is, the step surface 30d and the extension part 2 can be in direct contact to achieve the stopping effect, or can be in indirect contact to achieve the stopping effect. For example, the mounting structure 3 can be arranged at the lower position of the extension part 2, and the mounting structure 30c can be arranged on the step surface 30d. When the mounting structure 30c is connected with the mounting structure 3, the step surface 30d stops at the bottom of the extension part 2.

[0323] Therefore, when the battery 30 is actually installed, when the upper battery part 30a is installed from bottom to top, the bottom of the extension part 2 and the stopper of the step surface 30d can be used to remind the battery 30 to be assembled in place, so as to avoid the problem of excessive upward compression of the battery 30 and hitting the bottom of the vehicle, thereby protecting the battery 30. In addition, setting the size of the lower battery part 30b larger than that of the upper battery part 30a can further increase the size of the battery 30 to a certain extent, thereby further improving the size energy density of the battery 30.

[0324] In some embodiments, please refer to Fig.11 and Fig.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 that penetrates along the length direction of the vehicle beam 20 (such as the first direction X) and has an open top between the two battery side portions 30e and the battery central portion 30f.

[0325] 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.

[0326] Therefore, when the battery 30 is installed upwardly on the bottom of the vehicle, at least part of the beam 20 can be stored in the clearance groove 30g and located above the central part 30f of the battery, and the upper parts of the two battery side parts 30e can be located on both sides of the width direction of the beam 20, so that the space on both sides of the width direction of the beam 20 can be fully utilized to arrange a larger battery 30. Therefore, the structure of the battery 30 is ingenious, and the space on both sides of the width of the beam 20 is fully utilized by avoiding the beam 20, so that the overall size of the battery 30 can be increased to improve the size energy density of the battery 30.

[0327] In some embodiments, please refer to Fig.11 and Fig.12 , at least one of the battery side portion 30e and the battery central portion 30f is detachably connected to the mounting structure 3. Wherein, "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 detachably connected to the corresponding mounting structure 3 respectively.

[0328] 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.

[0329] Among them, the battery central part 30f can be detachably connected to the mounting structure 3 through the mounting structure 30c on the battery central part 30f. The position of the mounting structure 30c on the battery central part 30f is not limited, for example, it can be located in the middle, upper or lower part of the battery central part 30f.

[0330] 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.

[0331] When both battery side portions 30e are connected to the mounting structure 3, or when both the battery side portion 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, at least one of the battery side portion 30e and the battery center portion 30f is detachably connected to the mounting structure 3, which is conducive to improving the design flexibility of the battery 30.

[0332] It is worth noting that the shape of the battery 30 of the embodiment of the present application is not limited thereto, and 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, etc.

[0333] In some embodiments of the present application, Fig.13 and Fig.14 As shown, for any embodiment of the battery mounting rack 10 of the present application, it 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 body form a circuit and / or fluid connection.

[0334] 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.

[0335] 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 through docking terminals, or by plugging wires and / or pipes. In addition, the sum of the other parts of the vehicle 1000 except the battery 30 and the battery mounting frame 10 can be understood as the vehicle body, and the vehicle beam 20 is a part of the vehicle body.

[0336] For example, when the docking structure 6 is used to achieve circuit connectivity, it can be used for current transfer between the vehicle 1000 and the battery 30, so that the battery 30 supplies power to the vehicle 1000, and the vehicle 1000 controls the battery 30, etc. For example, when the docking structure 6 is used to achieve fluid communication, it can be used for heat transfer between the thermal management system of the vehicle 1000 and the battery 30, so that the temperature of the battery 30 can be adjusted by the thermal management system to improve the working reliability and safety of the battery 30, or the thermal management system can be used to absorb the waste heat of the battery 30 to meet the heat source demand of the heat pump air conditioning system of the vehicle 1000, etc., which will not be elaborated here.

[0337] Therefore, by providing the docking structure 6 on the battery mounting frame 10, the connection requirements of the circuit and / or fluid path between the battery 30 and the vehicle body can be met through the structural design of the battery mounting frame 10, 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 specifically selected according to the shape of the battery mounting frame 10.

[0338] In some embodiments, Fig.13 As shown, the docking structure 6 can be arranged on the main body 1, and the mounting structure 3 can be arranged on the extension part 2. The main body 1 and the extension part 2 are connected to form the frame body 10a, which means that the docking structure 6 and the mounting structure 3 are both integrated in the frame body 10a. When using such a battery mounting frame 10 to install the battery 30 on the vehicle body, the mounting installation of the battery 30 can be realized through the mounting structure 3 integrated on the frame body 10a, and the circuit and / or liquid connection between the battery 30 and the vehicle body can be realized through the docking structure 6 integrated on the frame body 10a, so that there is no need to connect wires and pipes, which simplifies the cumbersome battery replacement operation and improves the battery replacement efficiency. And because the mounting structure 3 and the docking structure 6 are both integrated on the frame body 10a, the mounting connection position of the battery 30 is consistent with the reference reference of the water-electricity docking position, that is, the reference reference is the frame body 10a, so that the success rate of battery replacement can be improved.

[0339] In some embodiments, the docking structure 6 may include a first docking structure and a second docking structure, the first docking structure is used to dock with the circuit terminal on the battery 30, and the second docking structure is used to dock with the liquid path port on the battery 30. The relative positions of the first docking structure and the second docking structure are not limited, for example, they can be spaced apart in the horizontal direction, 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 docking. Of course, the first docking structure and the second docking structure mentioned above are only used to illustrate part of the docking structure 6, and do not represent a limitation thereto.

[0340] In some embodiments, Fig.13 and Fig.14 As shown, the main body 1 has a beam avoidance groove 13, the beam avoidance groove 13 has an opening that passes through along the length direction (such as the first direction X) of the beam 20, and the docking structure 6 is located in the beam avoidance groove 13. In the embodiment 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.

[0341] Therefore, by providing the beam avoidance groove 13 on the main body 1, when the main body 1 is connected to the vehicle body, at least part of the beam 20 can extend into the beam avoidance groove 13, and the extension direction of the beam 20 is the same as the through direction of the opening, so as to avoid interference between the battery mounting frame 10 and the beam 20, improve the compactness of the matching between the battery mounting frame 10 and the beam 20, and facilitate the use of the space near the beam 20 to set the battery 30, thereby facilitating the increase of the size and dimensional energy density of the battery 30. Moreover, by providing the docking structure 6 in the beam avoidance groove 13, the space in the beam avoidance groove 13 can be fully utilized to improve the space utilization rate, and it is convenient to reduce the space occupied by the docking structure 6 at other positions of the battery mounting frame 10, thereby increasing the size and dimensional energy density of the battery 30.

[0342] Moreover, the docking structure 6 can obtain the protection of the inner wall of the beam avoidance groove 13, so as to reduce the probability of the docking structure 6 being damaged by collision, improve the problem of the docking structure 6 being corroded and failed by mud and water, etc., improve the reliability and stability of docking, and reduce the risk of electrical failure caused by mud and splashing water erosion of the docking structure 6. Moreover, the docking structure 6 does not need to occupy the space outside the beam 20, and will not interfere with the connection between the battery mounting frame 10 and the beam 20 or the battery 30. At the same time, it is conducive to shortening the distance between the vehicle body and the docking structure 6, so as to reduce the difficulty of connecting the vehicle body and the docking structure 6.

[0343] In some embodiments, Fig.13 and Fig.14 As shown, the main body 1 includes a plurality of first main body walls 11 spaced apart along the length direction (such as the first direction X) of the vehicle beam 20, and an escape opening 15 is formed between two adjacent first main body walls 11, and the docking interface (such as the interface of the circuit and / or the interface of the fluid path) of the docking structure 6 is higher than the first main body wall 11 and is arranged corresponding to the escape opening 15. Here, the height direction of the vehicle body is defined as the up-and-down direction, and the height direction of the vehicle body is consistent with the height direction of the vehicle 1000, both of which are up-and-down in the gravity direction.

[0344] Therefore, since the docking interface of the docking structure 6 is higher than the first main body wall 11, the height of the docking interface of the docking structure 6 from the ground is relatively large, so that better protection can be obtained. 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, improve the compactness of the matching between 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 30. Moreover, by setting the avoidance opening 15, when the battery 30 is mounted on the battery mounting frame 10, a part of the battery 30 can extend upward into the avoidance opening 15 and dock with the docking interface of the docking structure 6, thereby meeting the docking requirements.

[0345] In some embodiments, Fig.13 and Fig.14 As shown, 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 leg portion 612. The docking device 62 is arranged on the load-bearing portion 611. The 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.

[0346] In the above technical solution, by arranging the docking device 62 on the bearing portion 611, and arranging the support leg portions 612 to extend from both ends of the 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, the bearing portion 611 can be spaced apart from the first main body wall 11, so that the 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 dimension of the battery 30.

[0347] 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 increase the size and energy density of the battery 30 in the width direction of the vehicle 1000.

[0348] In some embodiments, Fig.13 and Fig.14 As shown, the bearing portion 611 is provided with 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 .

[0349] Therefore, by providing the third weight-reducing structure 613 on the bearing portion 611, the weight of the bearing portion 611 is reduced, and the weight of the docking structure 6 is further reduced, so as to achieve a lightweight design of the docking structure 6. The third weight-reducing structure 613 may include but is not limited to a weight-reducing hole, a weight-reducing groove, or a thinning process.

[0350] Therefore, by setting the first reinforcement structure 614 at the connection between the bearing part 611 and the leg part 612, the structural strength of the connection between the bearing part 611 and the leg part 612 is enhanced, and the possibility of fracture at the connection between the leg part 612 and the bearing part 611 is reduced, which is conducive to reducing the thickness of the bearing part 611 and the leg part 612, so as to achieve a lightweight design of the docking structure 6. Among them, the first reinforcement structure 614 can include but is not limited to reinforcement ribs, strip reinforcement protrusions, or partial thickening of the extension part 2, and when the first reinforcement structure 614 is set as reinforcement ribs, the structural form of the reinforcement ribs is not limited, for example, it can be straight, curved, or cross-shaped, etc.

[0351] In some embodiments, Fig.13 and Fig.14 As shown, the carrier 61 is an integrally formed part and is assembled and connected with 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 it is beneficial to ensure the overall structural strength of the carrier 61, and the carrier 61 is assembled and connected with the first main body wall 11, so as to reduce the difficulty of assembling the carrier 61 and the first main body wall 11, and improve the production efficiency of the battery mounting rack 10.

[0352] 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. The "assembled connection" includes but is not limited to welding, bolting, clamping, or plugging.

[0353] In some embodiments, Fig.13 and Fig.14 As shown, both the battery mounting space 4 and the avoidance opening 15 can be set to be multiple and spaced along the length direction (such as the first direction X) of the vehicle beam 20, and the avoidance opening 15 corresponds to the battery mounting space 4 along the width direction (such as the second direction Y) of the vehicle beam 20 one by one, and each avoidance opening 15 is respectively provided with a docking structure 6. Therefore, when the size of the battery 30 is large, the part of the battery 30 corresponding to the battery mounting space 4 can be extended into the battery mounting space 4, and the part corresponding to the avoidance opening 15 can be extended 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 frame 10, the plurality of docking structures 6 can be used to respectively realize the connection requirements of the plurality of batteries 30 with the circuits and / or fluid paths of the vehicle body, that is, each battery 30 can realize the connection requirements of 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 realize separate connection with each battery 30 through the corresponding docking structure 6, which is beneficial for each battery 30 to be powered separately or controlled separately by the vehicle body.

[0354] In some embodiments, please refer 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 (such as the first direction X) of the vehicle beam 20, the docking structures 6 can be provided in plurality and spaced apart along the length direction (such as the first direction X) of the vehicle beam 20, 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 (such as the first direction X) of the vehicle beam 20 (for example, at an acute angle, an obtuse angle, or a right angle).

[0355] 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 does 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.

[0356] 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 arranged at intervals along the width direction of the vehicle, and the cross beam 202 is connected between the two longitudinal beams 201. Since the vehicle beam 20 includes two longitudinal beams 201 extending along the length direction of the vehicle beam 20 (such as the first direction X) and arranged at intervals along the second direction Y, the second direction Y can be set to be orthogonal to the length direction of the vehicle beam 20 (such as the first direction X).

[0357] In some embodiments, when the vehicle beam 20 includes two longitudinal beams 201 extending along the length direction of the vehicle beam 20 and spaced apart along the width direction of the vehicle beam 20, the docking structure 6 can be disposed between the two longitudinal beams 201, and the two longitudinal beams 201 can be used to protect the docking structure 6 to a certain extent, thereby reducing damage to the docking structure 6, which is conducive to extending the service life of the docking structure 6, and enabling the docking structure 6 to fully utilize the space between the two longitudinal beams 201 to improve space utilization, and facilitate reducing the volume of the battery mounting frame 10, thereby increasing the capacity of the battery 30, and the portion of the docking structure 6 located between the two longitudinal beams 201 can be protected by the two longitudinal beams 201, so as to reduce the probability of the docking structure 6 being damaged by collision, improve the problem of the docking structure 6 being corroded and failed by muddy water, etc., improve the reliability and stability of docking, and reduce the risk of electrical failure of the docking structure 6 caused by muddy water and splashing water erosion. Moreover, the docking structure 6 does not need to occupy space outside the vehicle beam 20, and will not interfere with the cooperation of the battery mounting frame 10 with the vehicle beam 20 and the battery 30.

[0358] In some embodiments, Fig.13 and Fig.14 As shown, 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 height of the docking interface of the docking structure 6 is relatively large from the ground, which can obtain better protection, and 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 docked with the docking structure 6 while being mounted from bottom to top, thereby improving the efficiency of battery replacement.

[0359] 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.

[0360] In some embodiments, Fig.13 and Fig.14 As shown, 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 height of the docking interface of the docking structure 6 is relatively large from the ground, which can obtain better protection, and 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 docked with the docking structure 6 while being mounted from bottom to top, thereby improving the efficiency of battery replacement.

[0361] 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.

[0362] In some embodiments, please refer to Fig.15 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 that runs through the length direction of the vehicle beam 20 (such as the first direction X) and has an open top between the two battery side portions 30e and the battery central portion 30f. At this time, a docking portion 30h for docking with the docking structure 6 can be set on the top of the battery central portion 30f.

[0363] Therefore, when the battery 30 moves from bottom to top along the height direction of the vehicle 1000, the docking part 30h of the battery 30 can be easily docked with the docking structure 6 between the two longitudinal beams 201, which is conducive to reducing the difficulty of battery replacement operation, improving the efficiency of battery replacement, and saving the space required for battery replacement operation. Further, when the docking interface of the docking structure 6 is set downward, the battery 30 can be docked with the docking structure 6 while being mounted on the mounting structure 3 from bottom to top, so that the docking space when the battery 30 is docked 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 moving 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 moving direction, and then there is no need to set up an additional docking space in the length or width direction of the vehicle 1000, so as to improve the space utilization rate, and make the battery 30 battery replacement and battery 30 docking can be carried out simultaneously, thereby improving the battery replacement efficiency.

[0364] In recent years, battery swapping has become an important way for commercial electric vehicles to supplement energy in some application scenarios such as logistics, docks, and mines, and the pace of battery swapping station construction has also begun to accelerate. In order to make battery swapping universal and interchangeable, battery swapping facilities such as battery swapping stations and charging equipment can be fully utilized to reduce resource waste.

[0365] This application proposes some embodiments of chassis-type battery replacement to improve the compatibility and interchangeability of battery replacement. However, the following embodiments are not limited to pure electric vehicles, and other forms of battery replacement vehicles can be used for reference.

[0366] In some embodiments, the operating voltage range of the battery replacement system is: 400V~750V.

[0367] In some embodiments, the flatness of the battery swap contact surface of the battery swap system is ≤4mm. Specifically, the contact interface between the battery swap system and the battery mounting frame should be a plane without convex structures, and the flatness should be less than 4mm.

[0368] In some embodiments, the dimensional tolerance of the battery replacement system is within ±10 mm.

[0369] 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.

[0370] In some embodiments, Figure 16-17 As shown, the battery swap system should be replaced on the vehicle with the corresponding envelope space. The battery size in the battery swap system is as follows: Figure 18-Figure 19 Logo.

[0371] In some embodiments, reference Figure 16-Figure 19 , a safety gap L0 is reserved between the front and rear end surfaces of the battery swap system and the entire vehicle, L0 ≥ 50mm.

[0372] In some embodiments, reference Figure 16-Figure 19 The dimension L of the battery replacement system along the vehicle length direction shall meet the following requirements: 700mm≤L≤900mm; or 1500mm≤L≤1700mm; or 2300mm≤L≤2500mm; or 3100mm≤L≤3300mm.

[0373] In some embodiments, reference Figure 16-Figure 19 The dimension W of the battery replacement system along the vehicle width direction satisfies: 2300mm≤W≤2550mm.

[0374] In some embodiments, reference Figure 16-Figure 19 The total height H of the battery replacement system satisfies: H≤680mm.

[0375] In some embodiments, reference Figure 16-Figure 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.

[0376] In some embodiments, reference Figure 16-Figure 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.

[0377] In some embodiments, reference Figure 16-Figure 19 The width dimension W2 of the upper middle boss of the battery replacement system (such as the upper part 30a of the battery in the central part 30f of the battery) satisfies: W2≤640mm.

[0378] In some embodiments, reference Figure 16-Figure 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.

[0379] In some embodiments, reference Figure 16-Figure 19 The height dimension H2 of the upper middle boss of the battery replacement system (such as the upper part 30a of the battery in the central part 30f of the battery) satisfies: H2≤150mm.

[0380] 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.

[0381] At present, the main models of heavy-duty electric vehicles are: 6*4 tractor, 4*2 tractor, 8*4 dump truck, 6*4 dump truck, 4*2 truck, 6*4 truck. Among them, the 6*4 tractor and 8*4 dump truck have relatively short wheelbases, and other models are compatible. Among them, 6*4 tractor: the wheelbase of traditional oil trucks is 3300mm, which is the ideal wheelbase, but it is impossible to arrange a large amount of electricity at this stage. For rear-mounted battery replacement models, the current wheelbase is extended to 3800mm, and this space cannot arrange the target electricity. At present, the client is encouraged to extend the wheelbase to 4200mm, and the battery space is decomposed based on this wheelbase. Among them, 8*4 dump trucks: some are used in cities, and some are used in mining areas. The wheelbase of 8*4 dump trucks in mining areas is longer to ensure the transportation volume, and the wheelbase is increased, so this space can arrange the target electricity. 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, and chassis battery swapping can be based on this extended wheelbase to decompose the battery space.

[0382] The space limiting factors at the front end of the battery include: leaf springs and their brackets. Considering the heavy load, the industry generally has a space of about 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 gap of 20 to 30 mm between the battery swap system and the battery swap system, the length envelope size of each battery swap system is approximately: 700 to 820 mm.

[0383] 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 vehicle is 2550mm.

[0384] When designing the height envelope dimensions 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 dimensions of the battery swap system are approximately 580-780mm.

[0385] 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.

[0386] In some embodiments, reference Fig. 20 In the length direction of the vehicle (such as the first direction X), the length of the battery mounting space 4 is Y1, and satisfies: 620mm≤Y1≤720mm.

[0387] In some embodiments, reference Fig. 20 In the width direction of the vehicle (such as the second direction Y), the width of the battery mounting space 4 is N1, and satisfies: 690mm≤N1≤815mm.

[0388] In some embodiments, reference Fig. 20 In the width direction of the vehicle (such as 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: 660mm≤N2≤680mm.

[0389] In some embodiments, reference Fig.21 In the width direction of the vehicle (such as the second direction Y), the total width of the battery mounting bracket 10 is P, and in the length direction of the vehicle (such as the first direction X), the total length of the battery mounting bracket 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).

[0390] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application is 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 replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should 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.
