[0003] The present application relates to the technical field of new energy vehicles, and in particular to a vehicle frame and a vehicle. Background Art

[0004] New energy vehicles have become an important part of the sustainable development of the vehicle industry due to their energy-saving and environmentally friendly advantages. With the development of new energy vehicles, people's requirements for the cruising range of new energy vehicles are also increasing.

[0005] For new energy vehicles, how to increase the driving range is a technical problem that needs to be solved urgently.

[0006] Summary of the Invention

[0007] In a first aspect, the present application provides a vehicle frame comprising two longitudinal beams, the two longitudinal beams being arranged side by side along a first direction. Along the longitudinal beams, a central portion of at least one of the two longitudinal beams is bent outward and bulged along the first direction to form a widened section. The widened section and the other longitudinal beam together form a receiving cavity for accommodating a battery. The frame is provided with a mounting portion for removably mounting the battery within the receiving cavity.

[0008] In the above solution, a widened section is provided in the middle of the longitudinal beam to alleviate the problem of interference with the battery due to the small spacing between the two longitudinal beams. The two longitudinal beams form a battery-accommodating cavity at the location corresponding to the widened section, allowing the battery to utilize the space between the two longitudinal beams. This allows vehicles with this frame to be equipped with more or larger batteries, thereby increasing the vehicle's range. Furthermore, by providing a mounting portion on the frame, the battery can be detachably installed, thus enabling vehicles with this frame to have a battery swapping function, allowing for timely replenishment of power loss during driving, thereby effectively increasing the vehicle's range.

[0009] According to some embodiments of the present application, the two longitudinal beams are respectively formed with a widened section, and the widened sections of the two longitudinal beams together form a receiving cavity for receiving the battery.

[0010] In the above solution, by providing widening sections on both longitudinal beams, the frame can effectively form a wider accommodating cavity at the position corresponding to the widening section, reducing the interference of the longitudinal beams on the battery and meeting the battery size requirements, so that the vehicle can be equipped with more or larger batteries to effectively improve the vehicle's cruising range.

[0011] According to some embodiments of the present application, along the first direction, a maximum distance between the widened section of one longitudinal beam and the widened section of another longitudinal beam is W, satisfying 2000 mm ≤ W ≤ 2500 mm.

[0012] In the above solution, by limiting the maximum spacing W between the two longitudinal beams to no less than 2000mm and no more than 2500mm, on the one hand, the width of the accommodating cavity can meet the size requirements of the battery, so that the battery can be accommodated between the two longitudinal beams, thereby enabling the vehicle to be equipped with more or larger batteries, thereby improving the vehicle's cruising range; on the other hand, it can also reduce the impact of the large spacing between the two longitudinal beams on the vehicle width, thereby meeting the vehicle's driving requirements.

[0013] According to some embodiments of the present application, W=2450 mm.

[0014] In the above solution, by limiting the maximum spacing W between the two longitudinal beams to 2450mm, the size requirements of the battery can be met, so that the battery can be accommodated in the accommodating cavity, allowing the vehicle to be equipped with more or larger batteries to increase the vehicle's cruising range.

[0015] According to some embodiments of the present application, the accommodating cavity has a downward opening to allow the battery to enter or leave the accommodating cavity.

[0016] In the above solution, by providing an opening at the bottom of the storage chamber, the battery can enter or exit the storage chamber from under the frame, enabling the vehicle to have the function of bottom battery replacement, meeting the vehicle's battery replacement needs. In some embodiments, such as the battery replacement scenario of heavy trucks, by providing a trench at the battery replacement site, when the heavy truck drives into the trench, the battery can be replaced from under the heavy truck.

[0017] According to some embodiments of the present application, the vehicle frame further includes a first cross beam, both ends of which are respectively connected to the widened sections of the two longitudinal beams.

[0018] In the above solution, by connecting the two ends of the first crossbeam to the two widened sections respectively, the structural strength of the frame can be effectively improved, other components of the vehicle can be effectively carried and the battery can be effectively arranged, so that the vehicle has higher driving reliability.

[0019] According to some embodiments of the present application, there are multiple first cross beams, and the multiple first cross beams are spaced apart along the length direction of the longitudinal beam to divide the accommodating cavity into multiple sub-chambers, each sub-chamber being used to accommodate a battery respectively.

[0020] In the above scheme, multiple first cross beams are arranged at intervals along the length direction of the longitudinal beam. On the one hand, this can effectively improve the structural strength of the frame and improve the reliability of the frame; on the other hand, it can divide the accommodating cavity into multiple sub-chambers to separate multiple batteries and reduce the impact between batteries, or provide multiple support points for the batteries to improve the connection stability between the batteries and the frame.

[0021] According to some embodiments of the present application, at least a portion of the mounting portion is disposed on the first crossbeam.

[0022] In the above solution, by arranging at least part of the mounting portion on the first crossbeam, the first crossbeam can serve as a structural member to enhance the structural strength and also can serve as a battery mounting member, thereby making the frame highly integrated and lightweight, thereby increasing the cruising range of the vehicle having the frame.

[0023] According to some embodiments of the present application, at least a portion of the mounting portion includes a mounting hole provided on the first beam.

[0024] In the above solution, the battery can be mounted by setting a mounting hole on the first crossbeam, which reduces the difficulty of mounting the battery on the frame and improves the efficiency of battery replacement.

[0025] According to some embodiments of the present application, at least a portion of the mounting portion is disposed on the longitudinal beam.

[0026] In the above solution, by arranging at least a portion of the mounting portion on the longitudinal beam, the vehicle frame can effectively carry the battery, so that the battery is stably arranged in the accommodating cavity, thereby improving the reliability of vehicle driving.

[0027] According to some embodiments of the present application, along the length direction of the longitudinal beam, at least one of the two longitudinal beams includes a first segment, a widening segment, and a second segment that are interconnected. Along the first direction, the maximum spacing between the widening segment and the other longitudinal beam is greater than the maximum spacing between the first segment and the other longitudinal beam, and the maximum spacing between the widening segment and the other longitudinal beam is greater than the maximum spacing between the second segment and the other longitudinal beam.

[0028] In the above solution, a widening section is provided between the first and second sections of at least one longitudinal beam to form a battery-accommodating cavity between the two longitudinal beams. This allows a vehicle with this frame to accommodate more batteries and reduces the impact of the widening section on the front and rear ends of the longitudinal beam, allowing them to be connected to other vehicle components.

[0029] According to some embodiments of the present application, the first section, the widening section, and the second section are integrally formed.

[0030] In the above solution, the first section, the widened section and the second section are formed as one piece, so that the longitudinal beam has higher rigidity and strength, thereby effectively meeting the load-bearing requirements of the frame, thereby making the vehicle with the frame more reliable.

[0031] According to some embodiments of the present application, the frame further includes a second cross beam, the two ends of which are respectively connected to the first section of the at least one longitudinal beam and the other longitudinal beam; and / or, the frame further includes a third cross beam, the two ends of which are respectively connected to the second section of the at least one longitudinal beam and the other longitudinal beam.

[0032] In the above solution, by providing a second crossbeam and / or a third crossbeam to connect the two longitudinal beams, the structural stability of the two longitudinal beams can be improved, thereby effectively meeting the load-bearing requirements of the frame, and further increasing the reliability of the vehicle having the frame.

[0033] In a second aspect, the present application further provides a vehicle comprising a battery and the vehicle frame provided in the first aspect. The battery is disposed in the accommodating cavity, and along a first direction, a projection of the longitudinal beam at least partially overlaps a projection of the battery.

[0034] In the above solution, by providing widening sections on the longitudinal beams of the frame to increase the width between the longitudinal beams, the battery can be placed between the two longitudinal beams, so that a vehicle with this frame can be equipped with more batteries to have a longer cruising range.

[0035] According to some embodiments of the present application, the battery is detachably disposed in the accommodating cavity.

[0036] In the above scheme, by limiting the battery to be detachably arranged in the accommodating cavity, the vehicle can have a battery replacement function, so that the power loss of the vehicle during driving can be replenished in time by battery replacement, thereby effectively improving the vehicle's cruising range.

[0037] According to some embodiments of the present application, the accommodating cavity has a downward opening to allow the battery to enter or exit the accommodating cavity.

[0038] In the above solution, by setting an opening at the bottom of the accommodating cavity, the battery can enter or leave the accommodating cavity from the bottom of the frame, so that the vehicle has the function of bottom battery replacement and meets the battery replacement needs of the vehicle.

[0039] According to some embodiments of the present application, the length direction of the battery is parallel to or perpendicular to the first direction.

[0040] In the above solution, the first direction can be the width of the frame or the width of the vehicle. By arranging the battery's length direction parallel to the first direction, the center of gravity of the battery can be brought closer to the center of gravity of the vehicle, thereby improving the reliability of the vehicle. By arranging the battery's length direction perpendicular to the first direction, the weight of the battery can be distributed along the length of the vehicle, reducing the battery's impact on the front and rear weight of the vehicle and improving the reliability of the vehicle.

[0056] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0057] In some embodiments, the battery cells may be secondary batteries, which are batteries that can be recharged to activate their active materials after discharge and continue to be used. The battery cells may be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, and the like, although this disclosure is not intended to limit this.

[0058] Currently, new energy vehicles consist of a frame and battery. The frame, commonly known as a girder, is a framework-like structure that spans the front and rear axles of the vehicle and serves as the vehicle's foundation. Its functions include supporting and connecting the vehicle's various assemblies, ensuring their relative positioning and bearing various internal and external loads. The frame consists of two side-by-side longitudinal beams. The battery is typically mounted on the frame.

[0059] For new energy vehicles, improving range is a pressing technical challenge. Current vehicle frames consist of two relatively straight longitudinal beams. Because the distance between the two beams is small, the batteries are always positioned below them in the vertical direction due to interference from the beams. Consequently, the available space for the batteries is limited, resulting in a smaller number of batteries or smaller batteries being mounted on the vehicle, which in turn affects the vehicle's range.

[0060] In view of this, in order to increase the number of batteries in a vehicle and improve the battery life, some embodiments of the present application provide a frame, which includes a longitudinal beam, the middle part of the longitudinal beam is bent outward and protrudes to form a widened section, so that a wider accommodating cavity is formed between the two longitudinal beams at a position corresponding to the widened section to accommodate the battery, thereby improving the problem of interference between the longitudinal beams and allowing the battery to utilize the space between the two longitudinal beams, so that the frame can mount more batteries or larger batteries to improve the vehicle's life.

[0061] The vehicle frame disclosed in the embodiments of the present application can be installed in, but is not limited to, a frame of a passenger vehicle, a frame of a commercial freight vehicle, or a frame of a vehicle of other nature. The vehicle disclosed in the embodiments of the present application can be used in, but is not limited to, a frame of a passenger vehicle, a frame of a commercial freight vehicle, or a frame of a vehicle of other nature.

[0062] Please refer to Figure 1, which is a schematic diagram of the structure of the vehicle in some embodiments of the present application. Vehicle 1000 can be a new energy vehicle, which can be a pure electric vehicle, a hybrid vehicle with replaceable batteries, or an extended-range vehicle with replaceable batteries. The vehicle includes a battery 200. Battery 200, battery 200 can be set at the bottom, head, or tail of the vehicle. Battery 200 can be used to power the vehicle. For example, battery 200 can be used as an operating power source for vehicle 1000, for the circuit system of vehicle 1000, such as for the working power requirements of vehicle 1000 during startup, navigation, and operation.

[0063] The vehicle 1000 may further include a controller 300 and a motor 400 . The controller 300 is used to control the battery 200 to supply power to the motor 400 , for example, to meet the power requirements of the vehicle 1000 during startup, navigation, and driving.

[0064] In some embodiments of the present application, the battery 200 can serve not only as the operating power source of the vehicle, but also as the driving power source of the vehicle, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle.

[0065] In some embodiments, vehicle 1000 further includes a frame. The frame can be a framework-like structure spanning the front and rear axles of the vehicle, commonly known as a beam, and serves as the vehicle's foundation. The frame's functions include supporting and connecting the various vehicle assemblies, ensuring they maintain relative correct positioning, and bearing various internal and external vehicle loads. Battery 200 is mounted on the frame.

[0066] Some embodiments of the present application provide a frame, please refer to Figures 2 to 4, Figure 2 is a three-dimensional diagram of the frame in some embodiments of the present application, Figure 3 is a structural schematic diagram of the frame in some embodiments of the present application, and Figure 4 is a schematic diagram of the frame and battery in some embodiments of the present application.

[0067] The vehicle frame 100 includes two longitudinal beams 10, which are arranged side by side along a first direction x. Along the longitudinal beam's length direction y, the middle portion of at least one of the two longitudinal beams 10 is bent outward and bulged along the first direction x to form a widened section 12. The widened section 12 and the other longitudinal beam 10 together form a receiving cavity 14 for accommodating the battery 200.

[0068] The longitudinal beam 10 may be the primary structure of the vehicle frame 100. The longitudinal beam's lengthwise direction y may be parallel to the vehicle's longitudinal direction. In some embodiments, one end of the longitudinal beam 10 corresponds to the front of the vehicle, while the other end corresponds to the rear of the vehicle. There are two longitudinal beams 10, arranged side by side along a first direction x. The first direction x may be perpendicular to the longitudinal beam's lengthwise direction y and parallel to the vehicle's widthwise direction. In some embodiments, the longitudinal beam 10 may be made of steel, aluminum alloy, or the like.

[0069] The phrase "along the longitudinal direction y of the longitudinal beam, the middle portion of at least one of the two longitudinal beams 10 is bent outwardly in the first direction x and bulges outwardly to form the widened section 12" can be understood as meaning that at least one of the two longitudinal beams 10 may have the following characteristics: the middle portion of the longitudinal beam 10 is bent outwardly in the first direction x (bending outward refers to bending in the first direction x in a direction away from the other longitudinal beam 10), such that the bent portion bulges outwardly relative to the unbent portion, thereby forming the widened section 12. In some embodiments, the longitudinal beam 10 may include a first section 11, a widened section 12, and a second section 13. The first section 11, the widened section 12, and the second section 13 are sequentially connected along the longitudinal direction y of the longitudinal beam. The widened section 12 bulges outward relative to the first section 11 and the second section 13, such that the distance between the widened section 12 and the other longitudinal beam 10 is greater than the distance between the first section 11 and the other longitudinal beam 10, and greater than the distance between the second section 13 and the other longitudinal beam 10.

[0070] In some embodiments, referring to FIG3 , the widening section 12 may include a transition portion 120 and a straight portion 121. The straight portion 121 extends straight along the longitudinal beam's lengthwise direction y. The ends of the straight portion 121 may be transitionally connected to the first section 11 and the second section 13 via the transition portions 120, respectively. In some embodiments, the transition portion 120 may be a straight structure. In some embodiments, the transition portion 120 may include an arc-shaped structure. As shown in FIG3 , the transition portion 120 may include three portions: the portions at the two ends have an arc-shaped transition structure, and the portion in the middle may have a straight transition structure.

[0071] The accommodating cavity 14 is a chamber formed between the two longitudinal beams 10 at locations corresponding to the widened sections 12. Due to the widened sections 12, the chamber can have a larger dimension in the first direction x, thereby enabling the battery 200 to be disposed between the two longitudinal beams 10 without interference from the longitudinal beams 10. In some embodiments, at least a portion of the battery 200 can be located within the accommodating cavity 14, that is, at least a portion of the battery 200 can be located between the two longitudinal beams 10.

[0072] In some embodiments, the formation of the accommodating cavity 14 may include: both longitudinal beams 10 have a widening section 12 , and the two widening sections 12 together form the accommodating cavity 14 ; or one of the two longitudinal beams 10 has a widening section 12 , and the widening section 12 and the other longitudinal beam 10 together form the accommodating cavity 14 .

[0073] Please refer to Figure 4 , where the portion of battery 200 located within accommodating cavity 14 is depicted with dashed lines. Compared to existing solutions where the narrow width of the vehicle frame 100 interferes with the battery 200 and prevents the battery 200 from being located between the two longitudinal beams 10, Figure 4 clearly shows that the provision of the widening section 12 allows the battery 200 to effectively utilize the space between the longitudinal beams 10, thereby enabling the installation of larger batteries or a greater number of batteries 200.

[0074] In the above solution, a widening section 12 is provided in the middle of the longitudinal beam 10 to improve the problem of interference with the battery 200 due to the small distance between the two longitudinal beams 10. The two longitudinal beams 10 form a receiving cavity 14 capable of accommodating the battery 200 at the position corresponding to the widening section 12, so that the vehicle having the frame 100 can be equipped with more or larger batteries 200, thereby improving the vehicle's cruising range.

[0075] According to some embodiments of the present application, referring to FIG3 , the two longitudinal beams 10 are respectively formed with a widened section 12 . The widened sections 12 of the two longitudinal beams 10 together form a receiving cavity 14 for receiving the battery 200 .

[0076] In some embodiments, a widened section 12 is formed in the middle of both longitudinal beams 10 of the frame 100 , that is, the middle portions of the two longitudinal beams 10 are bent outwards to form a larger accommodating cavity 14 in the middle portion of the frame 100 .

[0077] In some embodiments, the vehicle frame 100 has a centerline that is perpendicular to the first direction x. The widened sections 12 of the two longitudinal beams 10 are symmetrically arranged along the centerline.

[0078] In the above solution, by providing widening sections 12 on both longitudinal beams 10, the frame 100 can effectively form a wider accommodating cavity 14 at the position corresponding to the widening section 12, thereby reducing the interference of the longitudinal beam 10 on the battery 200 and meeting the size requirements of the battery 200, so that the vehicle can be equipped with more batteries 200 to effectively improve the vehicle's cruising range.

[0079] According to some embodiments of the present application, referring to FIG. 3 , along the first direction x, the maximum distance between the widened section 12 of one longitudinal beam 10 and the widened section 12 of another longitudinal beam 10 is W, satisfying 2000 mm ≤ W ≤ 2500 mm.

[0080] In some embodiments, along the first direction x, the maximum spacing between two widening sections 12 is W, and W satisfies 2000 mm≤W≤2500 mm, so that at least a portion of the battery 200 with a size not greater than 2500 mm can be located in the accommodating cavity 14 .

[0081] In some embodiments, along the first direction x, the maximum spacing W between two widening sections 12 can be 2000 mm, 2100 mm, 2200 mm, 2300 mm, 2400 mm, 2500 mm or any value between two adjacent values.

[0082] In some embodiments, the widening section 12 includes a straight portion 121 and a transition portion 120 , and the maximum distance W between two widening sections 12 may refer to the distance between the two straight portions 121 .

[0083] In the above scheme, by limiting the maximum spacing W between the two longitudinal beams 10 to no less than 2000 mm and no more than 2500 mm, on the one hand, the width of the accommodating cavity 14 can meet the size requirements of the battery 200, so that the battery 200 can be accommodated between the two longitudinal beams 10, thereby increasing the number of batteries 200 in the vehicle or providing larger batteries 200, thereby increasing the vehicle's cruising range; on the other hand, it can also reduce the impact on the vehicle width caused by the excessive spacing between the two longitudinal beams 10, thereby meeting the vehicle's driving requirements.

[0084] According to some embodiments of the present application, W=2450 mm.

[0085] In some embodiments, along the first direction x, the maximum distance W between the two widening sections 12 is 2450 mm, so that at least a portion of the battery 200 with a size not greater than 2450 mm can be located in the accommodating cavity 14 .

[0086] In the above solution, by limiting the maximum spacing W between the two longitudinal beams 10 to 2450 mm, the size requirement of the battery 200 can be met, so that the battery 200 can be accommodated in the accommodating cavity 14, and the vehicle can be equipped with more batteries 200 to improve the vehicle's cruising range.

[0087] In some embodiments, the longitudinal beam 10 may include a first section 11 and a second section 13, respectively disposed at either end of the widened portion. The spacing between the first sections 11 of the two longitudinal beams 10 may be w1, which may be 1000 mm. The spacing between the second sections 13 of the two longitudinal beams 10 may be w2, which may be 850 mm. The portion of the frame 100 corresponding to the first section 11 may be the front section of the frame 100, which may be used to mount the vehicle's front suspension and tires, steering system, cooling system, braking system, control system, etc. The portion of the frame 100 corresponding to the second section 13 may be the rear section of the frame 100, which may be used to mount the rear suspension and tires, center and rear axles, etc.

[0088] According to some embodiments of the present application, the vehicle frame 100 is provided with a mounting portion 15 , and the mounting portion 15 is used to detachably place the battery 200 in the accommodating cavity 14 .

[0089] In the above solution, by limiting the maximum spacing W between the two longitudinal beams 10 to 2450 mm, the size requirement of the battery 200 can be met, so that the battery 200 can be accommodated in the accommodating cavity 14, and the vehicle can be equipped with more or larger batteries 200 to improve the vehicle's cruising range.

[0090] According to some embodiments of the present application, please refer to FIG5 , which is an enlarged view of point A in FIG2 . The frame 100 is provided with a mounting portion 15 , which is used to detachably mount the battery 200 in the accommodating cavity 14 .

[0091] The mounting portion 15 is a structure for detachably mounting the battery 200 in the accommodating cavity 14. In some embodiments, the mounting portion 15 includes, but is not limited to, a mounting hole 150, mounting screws, and other structures that enable detachable connection with the battery 200. Referring to FIG. 4 , the mounting portion 15 may be a mounting hole 150 provided on the vehicle frame 100.

[0092] In some embodiments, the mounting portion 15 can be disposed on the longitudinal beam 10, or a portion of the mounting portion 15 can be disposed on the longitudinal beam 10. In some embodiments, the mounting portion 15 can be disposed on a structural member of the vehicle frame 100 other than the longitudinal beam. For example, the vehicle frame 100 can further include a crossbeam that connects two longitudinal beams 10, and the mounting portion 15 can be disposed on the crossbeam, or a portion of the mounting portion 15 can be disposed on the crossbeam.

[0093] In the above scheme, by providing the mounting portion 15 on the frame 100, the battery 200 can be detachably installed, so that the vehicle with the frame 100 has a battery replacement function, and the battery replacement method can be used to timely replenish the power loss of the vehicle during driving, thereby effectively improving the vehicle's cruising range.

[0094] In some other embodiments of the present application, the frame 100 may not be provided with the mounting portion 15, and the battery 200 may be fixed to the frame 100, that is, the vehicle may not have a battery replacement function.

[0095] According to some embodiments of the present application, the accommodating cavity 14 has a downward opening 140 to allow the battery 200 to enter or exit the accommodating cavity 14 .

[0096] “The accommodating cavity 14 has a downward opening 140 ” can be understood as, along the direction of gravity, the opening 140 of the accommodating cavity 14 is located at the bottom of the frame 100 , so that the battery 200 can be moved out of the frame 100 from top to bottom, and the battery 200 can be arranged in the accommodating cavity 14 from bottom to top.

[0097] In some embodiments, the battery exchange site may be provided with a trench, in which battery exchange equipment may be installed. The vehicle to be battery exchanged may travel to the top of the trench, and the battery of the vehicle may be exchanged from the bottom of the vehicle by the battery exchange equipment.

[0098] In the above solution, by providing an opening 140 at the bottom of the accommodating cavity 14, the battery 200 can enter or exit the accommodating cavity 14 from below the frame 100, thereby enabling the vehicle to have the function of bottom-mounted battery replacement, meeting the vehicle's battery replacement needs. In some embodiments, such as in a heavy truck battery replacement scenario, by providing a trench at the battery replacement site, the battery 200 can be replaced from under the heavy truck when it drives into the trench.

[0099] According to some embodiments of the present application, referring to FIG. 2 to FIG. 5 , the vehicle frame 100 further includes a first crossbeam 16 , and two ends of the first crossbeam 16 are respectively connected to the widened sections 12 of the two longitudinal beams 10 .

[0100] The first crossbeam 16 is a structural member connecting the widened sections 12 of the two longitudinal beams 10. The first crossbeam 16 can extend along the first direction x, with one end connected to the inner side of one widened section 12 and the other end connected to the inner side of the other widened section 12.

[0101] In some embodiments, the material of the first cross beam 16 and the material of the longitudinal beam 10 can be the same, for example, both are steel or aluminum alloy. In other embodiments, the material of the first cross beam 16 and the material of the longitudinal beam 10 can be different.

[0102] In some embodiments, the first cross beam 16 can be connected to the longitudinal beam 10 by welding, screw connection, etc. In other embodiments, the first cross beam 16 can be integrally formed with the longitudinal beam 10.

[0103] In the above solution, by connecting the two ends of the first crossbeam 16 to the two widened sections 12 respectively, the structural strength of the frame 100 can be effectively improved, other components of the vehicle can be effectively carried and the battery 200 can be effectively arranged, so that the vehicle has higher driving reliability.

[0104] According to some embodiments of the present application, please refer to Figure 2, there are multiple first cross beams 16, and the multiple first cross beams 16 are spaced apart along the length direction y of the longitudinal beam to divide the accommodating cavity 14 into multiple sub-chambers 141, and each sub-chamber 141 is used to accommodate a battery 200 respectively.

[0105] In some embodiments, the number of first cross-beams 16 can be two, three, or more. For example, the vehicle frame 100 shown in Figures 2 and 3 has four first cross-beams 16, which together divide the accommodating cavity 14 into three sub-chambers 141. In some embodiments, each sub-chamber 141 can accommodate one battery 200 or the same number of batteries 200. In other embodiments, the three sub-chambers 141 can each accommodate a portion of a battery 200.

[0106] In the above scheme, multiple first cross beams 16 are arranged at intervals along the length direction y of the longitudinal beam. On the one hand, this can effectively improve the structural strength of the frame 100 and improve the reliability of the frame 100; on the other hand, it can divide the accommodating cavity 14 into multiple sub-chambers 141 to separate the multiple batteries 200, reduce the impact between the batteries 200, or provide multiple support points for the batteries 200 to improve the connection stability between the batteries 200 and the frame 100.

[0107] According to some embodiments of the present application, referring to FIG. 5 , at least a portion of the mounting portion 15 includes a mounting hole 150 disposed on the first beam 16 .

[0108] The phrase "at least a portion of the mounting portion 15 includes a mounting hole 150 disposed on the first crossbeam 16" can be understood to mean that part or all of the mounting portion 15 can be mounting holes 150, and the mounting holes 150 can be disposed on the first crossbeam 16. When the battery 200 is disposed in the accommodating cavity 14, a mounting member can be passed through the mounting holes 150 to secure the battery 200 within the accommodating cavity 14.

[0109] In some embodiments, referring to FIG. 3 and FIG. 5 , the first crossbeam 16 may include a main body 160 and a mounting portion 161 disposed at the bottom of the main body 160 . The main body 160 and the mounting portion 161 may both be sheet-shaped, and the mounting hole 150 may be disposed on the mounting portion 161 .

[0110] In some other embodiments, the mounting portion 15 may not only include a mounting hole 150 provided on the first cross beam 16 , but may also include other structural components provided on the longitudinal beam 10 that can realize the mounting of the battery 200 , such as a mounting hole 150 provided on the longitudinal beam 10 .

[0111] In the above solution, the mounting hole 150 is provided on the first cross beam 16 to enable the mounting of the battery 200 , thereby reducing the difficulty of mounting the battery 200 on the vehicle frame 100 and improving the efficiency of battery replacement.

[0112] According to some embodiments of the present application, at least a portion of the mounting portion 15 is disposed on the longitudinal beam 10 .

[0113] The phrase "at least a portion of the mounting portion 15 is disposed on the longitudinal beam 10" can be understood to mean that part or all of the mounting portion 15 may be mounting holes 150. These mounting holes 150 may be disposed on the longitudinal beam 10, for example, on both longitudinal beams 10. When the battery 200 is disposed in the accommodating cavity 14, a mounting member may be passed through the mounting holes 150 to secure the battery 200 within the accommodating cavity 14.

[0114] In some other embodiments, the mounting portion 15 may not only include a mounting hole 150 provided on the longitudinal beam 10, but may also include other structural components provided on the first cross beam 16 or other parts of the frame 100 that can realize the mounting of the battery 200, such as a mounting hole 150 provided on the first cross beam 16 or other parts of the frame 100.

[0115] In the above solution, by disposing at least a portion of the mounting portion 15 on the longitudinal beam 10 , the vehicle frame 100 can effectively carry the battery 200 , so that the battery 200 is stably disposed in the accommodating cavity 14 , thereby improving the reliability of vehicle driving.

[0116] According to some embodiments of the present application, referring to FIG3 , along the longitudinal direction y of the longitudinal beam, at least one of the two longitudinal beams 10 includes a first segment 11, a widening segment 12, and a second segment 13 that are interconnected.

[0117] In some embodiments, the middle portion of a longitudinal beam 10 is configured as a widened portion to increase the spacing between longitudinal beams 10 and accommodate batteries 200. A longitudinal beam 10 with this widened portion comprises a first section 11, a widened section 12, and a second section 13, connected in sequence along the longitudinal beam's length direction y. The widened section 12 protrudes outward from the first and second sections 11, 13, thereby forming a cavity 14 with another longitudinal beam 10 (or with the widened section 12 of another longitudinal beam 10) capable of accommodating a battery 200.

[0118] In some embodiments, along the first direction x, the distance between the first section 11 and another longitudinal beam 10 may be equal to or different from the distance between the second section 13 and another longitudinal beam 10 .

[0119] In the above solution, a widening section 12 is provided between the first section 11 and the second section 13 of at least one longitudinal beam 10 to form a cavity 14 between the two longitudinal beams 10, capable of accommodating the battery 200. This allows a vehicle with this frame 100 to accommodate more batteries 200. Furthermore, the widening section 12 reduces the impact on the front and rear ends of the longitudinal beam 10, allowing the front and rear ends of the longitudinal beam 10 to be connected to other vehicle components.

[0120] According to some embodiments of the present application, the first section 11 , the widening section 12 , and the second section 13 are integrally formed.

[0121] In some embodiments, the longitudinal beam 10 can be manufactured by an integral molding method such as compression molding.

[0122] In the above solution, the first section 11, the widened section 12 and the second section 13 are formed as one piece, so that the longitudinal beam 10 has high rigidity and strength, thereby effectively meeting the load-bearing requirements of the frame 100, and further increasing the reliability of the vehicle having the frame 100.

[0123] In some other embodiments, the first section 11, the widened section 12 and the second end can be connected as a whole by welding, screw connection, etc.

[0124] According to some embodiments of the present application, referring to Figures 2 and 3, the frame 100 further includes a second cross beam 17, the two ends of which are respectively connected to the first section 11 of the at least one longitudinal beam 10 and the other longitudinal beam 10; and / or, the frame 100 further includes a third cross beam, the two ends of which are respectively connected to the second section 13 of the at least one longitudinal beam 10 and the other longitudinal beam 10.

[0125] The second cross-beam 17 may be a beam structure disposed between two longitudinal beams 10 and may be used to enhance the structural strength of the vehicle frame 100. In some embodiments, the second cross-beam 17 may be disposed between the first section 11 and another longitudinal beam 10. In some embodiments, the second cross-beam 17 may be disposed between the second section 13 and another longitudinal beam 10. In some embodiments, the second cross-beam 17 may be disposed between the first section 11 and another longitudinal beam 10, and between the second section 13 and another longitudinal beam 10.

[0126] In some embodiments, both longitudinal beams 10 include a first section 11, a widened section 12, and a second section 13. A second crossbeam 17 is disposed between the first sections 11 of the two longitudinal beams 10, with both ends of the second crossbeam 17 connecting the inner sides of the two first sections 11. A second crossbeam 17 is disposed between the second sections 13 of the two longitudinal beams 10, with both ends of the second crossbeam 17 connecting the inner sides of the two second sections 13.

[0127] In the above solution, by providing the second crossbeam 17 and / or the third crossbeam to connect the two longitudinal beams 10, the structural stability of the two longitudinal beams 10 can be improved, thereby effectively meeting the load-bearing requirements of the frame 100, and further making the vehicle with the frame 100 highly reliable.

[0128] According to some embodiments of the present application, a vehicle is also provided. Please refer to Figure 6, which is a schematic diagram of a vehicle in some embodiments of the present application.

[0129] The vehicle includes a battery 200 and the vehicle frame 100 provided above. The battery 200 is disposed in the accommodation cavity 14, and along the first direction x, the projection of the longitudinal beam 10 at least partially overlaps with the projection of the battery 200.

[0130] “Along the first direction x, the projection of the longitudinal beam 10 at least partially overlaps with the projection of the battery 200 ” can be understood as, in the height direction, at least part of the battery 200 is located above the bottom surface of the longitudinal beam 10 , that is, at least part of the battery 200 can be located between the two longitudinal beams 10 to utilize the space between the two longitudinal beams 10 .

[0131] In the above solution, by providing a widening section 12 on the longitudinal beams 10 of the frame 10 to increase the width between the longitudinal beams 10, the battery 200 can be located between the two longitudinal beams 10, so that the vehicle having the frame 100 can be provided with more batteries 200 to have a higher cruising range.

[0132] According to some embodiments of the present application, the battery 200 is detachably disposed in the accommodating cavity 14 .

[0133] In some embodiments, the frame 100 may be provided with a mounting portion 15, and the mounting portion 15 may include a mounting hole 150 provided on the first cross beam 16 and / or the longitudinal beam 10, through which the battery 200 can be disassembled and assembled to realize the battery replacement function of the vehicle.

[0134] In the above scheme, by limiting the battery 200 to be detachably arranged in the accommodating cavity 14, the vehicle can have a battery replacement function, so that the power loss of the vehicle during driving can be replenished in time by battery replacement, thereby effectively improving the vehicle's cruising range.

[0135] According to some embodiments of the present application, the accommodating cavity 14 has a downward opening 140 to allow the battery 200 to enter or exit the accommodating cavity 14 .

[0136] The phrase "the accommodating chamber 14 has a downward opening 140 for the battery 200 to enter or exit the accommodating chamber 14" can be understood to mean that the battery 200 can be replaced from the bottom of the vehicle. For example, a battery swapping site can be provided with a trench in which battery swapping equipment can be installed. The vehicle to be replaced can then drive above the trench, where the battery swapping equipment can be used to replace the battery from the bottom of the vehicle.

[0137] In the above solution, by setting an opening 140 at the bottom of the accommodating cavity 14, the battery 200 can enter or leave the accommodating cavity 14 from below the frame 100, so that the vehicle has the function of bottom battery replacement and meets the battery replacement needs of the vehicle.

[0138] In the above scheme, by limiting the battery 200 to be detachably arranged in the accommodating cavity 14, the vehicle can have a battery replacement function, so that the power loss of the vehicle during driving can be replenished in time by battery replacement, thereby effectively improving the vehicle's cruising range.

[0139] According to some embodiments of the present application, referring to FIG. 3 and FIG. 4 , the length direction of the battery 200 is parallel to or perpendicular to the first direction x.

[0140] The length direction of the battery 200 is the direction of the largest dimension of the battery 200 . For example, the battery 200 may be in the shape of an elongated strip, and the direction of its long side may be the length direction of the battery 200 .

[0141] In some embodiments, the length direction of the battery 200 may be parallel to the first direction x, that is, the battery 200 is placed horizontally on the frame 100 , that is, both ends of the battery 200 are arranged corresponding to the width direction of the vehicle.

[0142] In some embodiments, the length direction of the battery 200 may be perpendicular to the first direction x, that is, the battery 200 is vertically placed on the frame 100 , that is, both ends of the battery 200 are arranged corresponding to the length direction of the vehicle.

[0143] In the above solution, the first direction x can be the width direction of the frame 100 or the width direction of the vehicle. By arranging the length direction of the battery 200 parallel to the first direction x, the center of gravity of the battery 200 can be close to the center of gravity of the vehicle, thereby improving the reliability of the vehicle. By arranging the length direction of the battery 200 perpendicular to the first direction x, the weight of the battery 200 can be distributed along the length of the vehicle, reducing the impact of the battery 200 on the front and rear weight of the vehicle and improving the reliability of the vehicle.

[0144] According to some embodiments of the present application, referring to Figures 2 to 5, a vehicle frame 100 is provided. The vehicle frame 100 includes a longitudinal beam 10, a first cross beam 16, and a second cross beam 17. There are two longitudinal beams 10, and the two longitudinal beams 10 are arranged side by side along the first direction x. Along the longitudinal direction y of the longitudinal beam, the longitudinal beam 10 includes a first section 11, a widening section 12, and a second section 13 that are integrally formed and connected in sequence. The widening section 12 may be the middle portion of the longitudinal beam 10, and the widening section 12 is bent outwardly along the first direction x to protrude relative to the first section 11 and the second section 13. The widening sections 12 of the two longitudinal beams 10 together form a accommodating cavity 14 that can accommodate a battery 200, so that the battery 200 can utilize the space between the two longitudinal beams 10, thereby enabling the vehicle to be equipped with more batteries 200 or larger batteries 200, thereby improving the vehicle's cruising range.

[0145] A first crossbeam 16 is disposed between the two widened sections 12. Both ends of the first crossbeam 16 are connected to the inner sides of the widened sections 12. The first crossbeam 16 is provided with mounting holes 150 for mounting components to pass through, enabling the assembly of the battery 200 and thus realizing the vehicle's battery replacement function. In some embodiments, there are multiple first crossbeams 16, each spaced apart along the longitudinal beam's lengthwise direction y.

[0146] The second cross beam 17 is disposed between the two first sections 11 and / or between the two second sections 13 to improve the structural strength of the vehicle frame 100 and enhance the load-bearing capacity of the vehicle frame 100 .
