Technical Field

[0002] This application relates to the field of new energy vehicle technology, specifically to vehicle bodies and vehicles.

Background Art

[0003] New energy vehicles have become an important component of the sustainable development of the vehicle industry due to their energy-saving and environmental protection advantages. With the development of new energy vehicles, the requirements for the cruising range of new energy vehicles have also increased. In order to meet the requirement that the power loss during the running of new energy vehicles can be timely replenished, a solution for timely replenishing power loss through power exchange has emerged.

[0004] For new energy vehicles, how to reduce the power exchange cost is a technical problem that urgently needs to be solved.

Summary of the Invention

[0005] This application provides a vehicle body and a vehicle that can effectively reduce the power exchange cost.

[0006] This application is realized by the following technical solutions.

[0007] According to a first aspect, the present application provides a vehicle body comprising a bracket assembly and a plurality of first connectors, the bracket assembly having a plurality of sets of first mounting parts, each set of first mounting parts being used to be detachably connected to a single battery, the number of first connectors being equal to the number of sets of first mounting parts, and each first connector being used to be connected to a second connector of a single battery.

[0008] In the above solution, the vehicle body includes a bracket assembly and a plurality of first connectors. By installing a plurality of first connectors and a plurality of first mounting parts on the bracket assembly, the number of batteries that need to be replaced can be adjusted according to the range demand (i.e., power can be replaced as needed; for example, if the required range is relatively short, a relatively small number of batteries can be mounted on the corresponding number of first mounting parts in the plurality of first mounting parts, and the second connector of each battery is connected to the corresponding first connector; if the required range is relatively long, a relatively large number of batteries can be mounted on the corresponding number of first mounting parts in the plurality of first mounting parts, and the second connector of each battery is connected to the corresponding first connector), thereby saving the cost of extra batteries and effectively reducing the cost of power replacement.

[0009] According to some embodiments of this application, the bracket assembly includes the vehicle body frame.

[0010] In the above plan, the vehicle frame may also serve as the main support for the vehicle body and can withstand various loads both inside and outside the vehicle body. The vehicle frame may also be equipped with a first mounting section, which allows for stable mounting of the battery, improves the stability of the connection between the battery and the vehicle body, and reduces the risk of the battery falling out. Furthermore, because the vehicle frame is located at the bottom of the vehicle body, the battery can be replaced from below the vehicle body. Compared to the current backpack-type power replacement in heavy trucks (where the battery is mounted behind the driver's cab of the heavy truck), this changes the battery's position layout within the vehicle body, effectively saving space in the longitudinal direction of the vehicle and improving the vehicle's load capacity.

[0011] According to some embodiments of this application, the bracket assembly further includes a bracket which is fixedly connected to the vehicle frame, and a first mounting portion is provided on the bracket.

[0012] In the above solution, by permanently connecting the bracket to the vehicle frame, the impact on the structural reliability of the vehicle body due to the installation of the bracket can be reduced, while the bracket can be stably installed on the vehicle body to effectively mount the battery. On the other hand, the bracket can be retrofitted to the existing vehicle frame, making retrofitting easier, faster, and allowing the current vehicle to quickly acquire the function of switching power as needed.

[0013] According to some embodiments of this application, the vehicle frame includes a first side member and a second side member, wherein the highest point of the bracket is below the upper end surface of the first side member and the highest point of the bracket is below the upper end surface of the second side member.

[0014] In the above plan, the vehicle frame may include a first side member and a second side member in the girder. For example, the vehicle frame may include a first side member and a second side member in the girder of a large vehicle (e.g., a heavy truck). By installing the bracket on the vehicle frame and ensuring that it does not extend beyond the upper end surfaces of the first and second side members, interference with the interior of the vehicle body can be reduced by attaching the bracket without occupying the space above the first and second side members. On the other hand, retrofitting the bracket to the current vehicle body is easier and more feasible. Furthermore, if the battery is attached to the bracket or to the first and second side members, the battery can exchange power from below the vehicle body. Compared to the current backpack-type power exchange in heavy trucks (where the battery is attached behind the driver's cab), this changes the battery's position layout in the vehicle body, effectively saving space in the longitudinal direction of the vehicle and improving the vehicle's load capacity.

[0015] According to some embodiments of this application, the bracket extends beyond the second side member along the direction in which the first side member is toward the second side member.

[0016] In the above solution, by installing the bracket so as to extend beyond the second side member, a larger mounting position can be provided for the battery, thereby allowing for the installation of more batteries or batteries with a larger volume, and adapting to the range requirements of different vehicles or different range requirements of vehicles.

[0017] According to some embodiments of this application, at least one first mounting portion is provided on the portion of the bracket that extends beyond the second side member.

[0018] In the above solution, by installing at least one first mounting part on the portion of the bracket that extends beyond the second side member, the battery can be stably connected to the bracket by connecting it to the portion of the battery that extends beyond the second side member, thereby improving the structural stability of the battery and the bracket.

[0019] According to some embodiments of this application, the bracket extends beyond the first side member, with the second side member aligned toward the first side member.

[0020] In the above solution, by installing the bracket so as to extend beyond the first side member, a larger mounting position can be provided for the battery, thereby allowing for the installation of more batteries or batteries with a larger volume to accommodate the range requirements of different vehicles or different range requirements of vehicles.

[0021] According to some embodiments of this application, at least one first mounting portion is provided on the portion of the bracket that extends beyond the first side member.

[0022] In the above solution, by installing at least one first mounting part on the portion of the bracket that extends beyond the first side member, the battery can be stably connected to the bracket by connecting it to the portion of the battery that extends beyond the first side member, thereby improving the structural stability of the battery and the bracket.

[0023] According to some embodiments of this application, at least a portion of the bracket is located between a first side member and a second side member.

[0024] In the above solution, the center of gravity of the vehicle body may be between the first side member and the second side member. Therefore, by installing at least a part of the bracket between the first side member and the second side member, the influence of the installation of the bracket on the position of the center of gravity of the vehicle body can be reduced, and the running stability of the vehicle body can be improved. On the other hand, when the battery is attached to the bracket, part of the battery or some of the batteries may be located between the first side member and the second side member. Therefore, the influence of the attachment of the battery on the position of the center of gravity of the vehicle body can be reduced, and the running stability of the vehicle body can be improved.

[0025] According to some embodiments of the present application, at least one first mounting portion is installed at a portion of the bracket located between the first side member and the second side member.

[0026] In the above solution, by installing at least one first mounting portion at a portion of the bracket located between the first side member and the second side member, and connecting to a portion of the battery between the first side member and the second side member, the battery can be stably connected to the bracket, and the structural stability of the battery and the bracket can be improved.

[0027] According to some embodiments of the present application, a second mounting portion for detachably connecting to the battery is installed on the vehicle body frame.

[0028] In the above solution, by installing the second mounting portion on the vehicle body frame and fitting it to the first mounting portion to detachably connect to the battery, the connection stability between the battery and the vehicle body can be improved, and the running reliability of the vehicle body can be improved.

[0029] According to some embodiments of the present application, the vehicle body frame includes a first side member and a second side member, and the second mounting portion is installed on the first side member and / or the second side member.

[0030] In the above solution, the vehicle frame may include a first side member and a second side member in the girder. For example, the vehicle frame may include a first side member and a second side member in the girder of a large vehicle (e.g., a heavy truck). By installing the second mounting portion on the first side member and / or the second side member, the first mounting portion can be effectively fitted, the battery can be effectively connected to the vehicle body, the risk of the battery falling out can be reduced, and the driving reliability of the vehicle body can be improved.

[0031] According to some embodiments of this application, the vehicle frame includes a first side member, a second side member, and a cross member, the cross member being connected between the first side member and the second side member, and the second mounting portion being installed on the cross member.

[0032] In the above solution, the vehicle frame may include a first side member, a second side member, and a cross member in the girder. For example, the vehicle frame may include a first side member, a second side member, and a cross member in the girder of a large vehicle (e.g., a heavy truck). By installing the second mounting portion on the cross member, it can be effectively fitted to the first mounting portion, effectively connecting the battery to the vehicle body, reducing the risk of the battery falling out, and improving the driving reliability of the vehicle body. On the other hand, since the cross member is located between the first side member and the second side member, by installing the second mounting portion on the cross member, the space between the first side member and the second side member can be rationally utilized, reducing interference of the second mounting portion with the bracket, and improving the power exchange efficiency of the vehicle body.

[0033] According to some embodiments of this application, the bracket assembly has a plurality of housing spaces, which are arranged along a first direction, each housing space is used to house one battery, and each housing space is fitted with a corresponding set of first mounting parts.

[0034] In the above-described method, multiple storage spaces are provided in the first direction, and a set of first mounting parts is provided corresponding to each storage space. This allows each battery to be neatly mounted in its corresponding storage space, preventing interference between batteries and improving the power exchange efficiency of the vehicle body.

[0035] According to some embodiments of this application, the housing space has an opening that opens downward, and the opening is used for the battery to enter and exit the housing space.

[0036] In the above design, by installing an opening that opens downwards, the battery can easily enter and exit the storage space from below the vehicle body. Compared to the current backpack-type power exchange design for heavy trucks, this saves space above the vehicle frame and reduces the risk of damage to the vehicle body due to interference with the vehicle body caused by the power exchange mechanism occupying space above the vehicle frame. At the same time, by changing the battery's position layout within the vehicle body, the battery can be positioned at the bottom of the vehicle body, effectively saving space in the longitudinal direction of the vehicle and improving the vehicle's load capacity.

[0037] According to some embodiments of this application, the first direction is parallel to the longitudinal direction of the vehicle frame.

[0038] In the above plan, the longitudinal direction of the vehicle frame may be parallel to the direction of travel of the vehicle body, or the longitudinal direction of the vehicle frame may be the direction in which the side members of the vehicle frame extend. By installing the first direction parallel to the longitudinal direction of the vehicle frame, that is, by installing multiple batteries so that they are aligned along the longitudinal direction of the vehicle frame, the center of gravity of the batteries is brought closer to the center in the lateral direction of the vehicle frame, reducing the influence of the battery mounting on the center of gravity of the vehicle body, and enabling the vehicle body to have relatively high driving reliability.

[0039] According to some embodiments of this application, the vehicle frame includes a first side member and a second side member, and each accommodation space is partitioned by the first side member and the second side member into a first subspace, a second subspace and a third subspace, the first subspace being located between the first side member and the second side member, the second subspace being located on the side of the first side member away from the second side member, and the third subspace being located on the side of the second side member away from the first side member.

[0040] In the above plan, the vehicle frame may include a first side member and a second side member in the girder. For example, the vehicle frame may include a first side member and a second side member in the girder of a large vehicle (e.g., a heavy truck). Based on the first and second side members, the storage space is divided into a first sub-space, a second sub-space, and a third sub-space, and the weight of the battery is distributed based on the positions of the first and second side members, reducing the impact of the battery mounting on the center of gravity of the vehicle body and allowing the vehicle body to have relatively high driving reliability.

[0041] According to some embodiments of this application, at least one first mounting portion is installed in a first subspace, at least one first mounting portion is installed in a second subspace, and at least one first mounting portion is installed in a third subspace.

[0042] In the above-described solution, by distributing and installing at least one first mounting section in the first sub-space, the second sub-space, and the third sub-space, the battery can be effectively connected, the battery can be stably attached to the vehicle body, the risk of the battery falling out can be reduced, and the vehicle body can be given relatively high driving reliability.

[0043] According to some embodiments of this application, at least two first mounting parts are provided in a first subspace, at least two first mounting parts are provided in a second subspace, and at least two first mounting parts are provided in a third subspace.

[0044] In the above-described method, at least two first mounting parts are distributed and installed in the first sub-space, the second sub-space, and the third sub-space, that is, at least six first mounting parts are installed within the housing space, and the six first mounting parts are arranged according to the first sub-space, the second sub-space, and the third sub-space. This ensures that the batteries are uniformly connected to the mounting parts under force, keeping the batteries stable within the housing space, reducing the risk of batteries falling out, and providing the vehicle body with relatively high driving reliability.

[0045] According to some embodiments of this application, at least two first mounting parts in a first subspace are installed on opposing sides of the first subspace along the longitudinal direction of the vehicle frame, and / or at least two first mounting parts in a second subspace are installed on opposing sides of the second subspace along the longitudinal direction of the vehicle frame, and / or at least two first mounting parts in a third subspace are installed on opposing sides of the third subspace along the longitudinal direction of the vehicle frame.

[0046] In the above-described solution, by installing at least two first mounting parts in the first sub-space on opposing sides along the longitudinal direction of the vehicle frame in the first sub-space, the battery is connected and restrained on both sides along the longitudinal direction of the vehicle frame, the force acting on the battery is made uniform, and the risk of the battery falling out is reduced. Similarly, by installing at least two first mounting parts in the second sub-space on opposing sides along the longitudinal direction of the vehicle frame in the second sub-space, the battery is connected and restrained on both sides along the longitudinal direction of the vehicle frame, the force acting on the battery is made uniform, and the risk of the battery falling out is reduced. Likewise, by installing at least two first mounting parts in the third sub-space on opposing sides along the longitudinal direction of the vehicle frame in the third sub-space, the battery is connected and restrained on both sides along the longitudinal direction of the vehicle frame, the force acting on the battery is made uniform, and the risk of the battery falling out is reduced, resulting in a relatively high level of driving reliability for the vehicle body.

[0047] According to some embodiments of this application, the first direction is parallel to the lateral direction of the vehicle frame.

[0048] In the above plan, the lateral direction of the vehicle frame may be perpendicular to the direction of travel of the vehicle body, the lateral direction of the vehicle frame may be the direction of arrangement of a pair of side members of the vehicle frame, or the lateral direction of the vehicle frame may be understood as the width direction of the vehicle body. By aligning the first direction parallel to the lateral direction of the vehicle frame, that is, by aligning multiple batteries along the lateral direction of the vehicle frame, power can be exchanged along the width direction of the vehicle body, which effectively reduces the battery movement path and improves power exchange efficiency compared to power exchange in the longitudinal direction of the vehicle body.

[0049] According to some embodiments of this application, the vehicle frame includes a first side member and a second side member, and the number of accommodation spaces is at least two, with at least one accommodation space located on the side of the first side member away from the second side member and at least one accommodation space located on the side of the second side member away from the first side member.

[0050] In the above plan, the vehicle frame may include a first side member and a second side member in the girder. For example, the vehicle frame may include a first side member and a second side member in the girder of a large vehicle (e.g., a heavy truck). By providing a storage space on the side of the first side member away from the second side member, and a storage space on the side of the second side member away from the first side member, that is, by placing batteries on both sides of the vehicle frame, the influence of battery mounting on the center of gravity of the vehicle body can be reduced, and the vehicle body can be given relatively high driving reliability.

[0051] According to some embodiments of this application, the number of accommodation spaces is at least three, and at least one accommodation space is located between the first side member and the second side member.

[0052] In the above-described solution, by placing the battery between the first and second side members, the influence of the battery's mounting on the vehicle's center of gravity is reduced, allowing the vehicle to have relatively high driving reliability.

[0053] According to some embodiments of this application, the first mounting portion is installed at least at one end along a first direction of the housing space.

[0054] In the above-described solution, by installing the first mounting portion at at least one end in the first direction of the housing space, the battery connection can be effectively restrained in the first direction, reducing the risk of the battery falling out and improving the driving reliability of the vehicle body.

[0055] According to some embodiments of this application, the first mounting portion is installed at opposing ends along a first direction of the housing space.

[0056] In the above plan, the first mounting portion is positioned opposite to the first direction of the housing space. BothBy installing it at the end, the battery connection can be effectively restrained in the first direction, the force applied to the battery can be made uniform, the risk of the battery falling out can be reduced, and the driving reliability of the vehicle body can be improved.

[0057] According to some embodiments of this application, the housing space has a first end and a second end facing each other along a first direction, and the first mounting portion installed at the first end and the first mounting portion installed at the second end are offset from each other.

[0058] In the above-described method, by offsetting the first mounting parts located at opposite ends of the storage space, the battery mounting process is made less prone to errors, reducing the risk of incorrect battery installation, while the bracket mounting process is also made less prone to errors, reducing the risk of incorrect bracket installation.

[0059] According to some embodiments of this application, the first mounting portions at the adjacent ends of two adjacent storage spaces are offset from each other.

[0060] In the above solution, during power exchange, multiple power exchange execution ends (e.g., power exchange batch heads) can simultaneously act on multiple first mounting parts and the parts where the batteries are connected to each other. Since two adjacent housing spaces move closer to each other in the first direction, by offsetting the first mounting parts at the adjacent ends of the two housing spaces, the risk of interference between two adjacent power exchange execution ends can be reduced, allowing multiple power exchange execution ends to operate simultaneously and improving power exchange efficiency.

[0061] According to some embodiments of this application, the size of the containment space along a first direction is smaller than the size along a second direction, and the first direction, the second direction, and the direction of gravity are perpendicular to each other.

[0062] In the above solution, the fact that the size of the housing space along the first direction is smaller than the size along the second direction may be understood as meaning that the size of the battery cell to be housed in the housing space is smaller along the first direction than the size along the second direction, that is, the size of the battery in the second direction may be the length of the battery. Therefore, the fact that the first mounting portion is installed at least one end along the first direction of the housing space may be understood as the first mounting portion corresponding to both sides of the relatively shorter size of the battery, which reduces the risk of the central part of the battery sinking downward due to gravity and improves the connection stability between the battery and the bracket, compared to the first mounting portion corresponding to both sides of the relatively longer size of the battery.

[0063] According to some embodiments of this application, the vehicle frame includes a pair of side members, and the bracket includes at least one mounting unit, each mounting unit including a mounting beam and a connecting portion, the mounting beam extending laterally along the vehicle frame, the connecting portion connected to the outer surface of the side member along the laterally along the vehicle frame, the mounting beam connected to the connecting portion, and a first mounting portion mounted on the mounting beam.

[0064] In the above solution, the vehicle frame may include a pair of side members in the girder. For example, the vehicle frame may include a pair of side members in the girder of a large vehicle (e.g., a heavy truck). By installing a connecting part, the mount beam and the side members can be effectively connected, the battery can be effectively mounted on the mount beam by the first mount part, the risk of the battery falling out can be reduced, and the driving reliability of the vehicle body can be improved.

[0065] According to some embodiments of this application, the connection extends along the direction of gravity.

[0066] In the above-described method, by positioning the connection point to extend along the direction of gravity, the connection point has a relatively large surface area in the direction of gravity and connects to the side member, thereby improving the connection stability between the mount beam and the side member, reducing the risk of battery detachment, and improving the driving reliability of the vehicle body.

[0067] According to some embodiments of this application, the mounting unit further includes a rib plate, which is located on the outside of the vehicle frame along the lateral direction of the vehicle frame, and the rib plate is connected to a connector and a mounting beam.

[0068] In the above-described method, by installing rib plates on the outside of the vehicle frame, the space between the connection point and the mounting beam can be used rationally, while at the same time improving the structural strength between the connection point and the mounting beam, reducing the risk of battery detachment, and improving the driving reliability of the vehicle itself.

[0069] According to some embodiments of this application, the connection portion includes a first subconnection portion and a second subconnection portion, the first and second subconnection portions each extending in opposite directions from the edge of the rib plate, and both the first and second subconnection portions are connected to the outer surface of the side member.

[0070] In the above-described solution, by installing a first sub-connection section and a second sub-connection section, and by installing the first and second sub-connection sections on both sides of the rib plate, the connection stability between the connection section and the side member is effectively improved, thereby effectively improving the structural stability between the connection section, the rib plate, and the mount beam, effectively reducing the risk of battery detachment, and improving the driving reliability of the vehicle body.

[0071] According to some embodiments of this application, the bracket includes a plurality of mounting units, which are spaced apart along the longitudinal direction of the vehicle frame, and the bracket further includes a connecting beam, which extends along the longitudinal direction of the vehicle frame, and which connects to two adjacent mounting units.

[0072] In the above-described method, by installing multiple mounting units, it is possible to mount batteries on multiple batteries and achieve the objective of exchanging power as needed, thereby reducing the cost of power exchange. At the same time, by installing connecting beams to connect two adjacent mounting units, the structural stability between the two adjacent mounting units can be effectively improved, increasing the capacity to mount batteries, reducing the risk of batteries falling out, and improving the driving reliability of the vehicle itself.

[0073] According to some embodiments of this application, each mounting unit includes two connecting parts, which are spaced apart along the lateral direction of the vehicle frame, and a pair of side members are located between the two connecting parts, with each connecting part connected to the outer surface of the corresponding side member.

[0074] In the above solution, by installing two connection points, the connection points are connected to the outer surfaces of the corresponding side members, meaning that the two side members of the vehicle frame are connected by their respective connection points. This provides a stable connection between the mount unit and the vehicle frame, reducing the risk of battery detachment and improving the reliability of vehicle operation. Furthermore, because two connection points are installed and spaced apart along the lateral direction of the vehicle frame, the mount beam can accommodate more first mount points, allowing for the mounting of larger batteries and further effectively improving the vehicle's range.

[0075] According to some embodiments of this application, the bracket includes a plurality of mounting units, which are spaced apart along the longitudinal direction of the vehicle frame, forming a housing space between two adjacent mounting units, each housing space being used to house one battery.

[0076] In the above-described method, multiple mounting units are installed at intervals along the longitudinal direction of the vehicle frame, forming multiple storage spaces aligned along the longitudinal direction of the vehicle frame. This allows each battery to be neatly mounted in its corresponding storage space, preventing interference between batteries and improving the power exchange efficiency of the vehicle body.

[0077] According to some embodiments of this application, each mounting unit includes one connector, and the number of brackets is two, with a pair of side members positioned between the two brackets along the lateral direction of the vehicle frame.

[0078] In the above solution, on the one hand, the mounting unit has a simple structure and is easy to manufacture. The mounting unit can stably connect the mounting beam to the outer surface of one of its side members by a single connection point, meaning that one bracket can be stably mounted on the outside of one of the side members of the vehicle frame. On the other hand, by installing brackets on both sides of the vehicle frame, more batteries can be mounted, increasing the upper limit of the number of power exchange batteries and further improving the vehicle's range.

[0079] According to some embodiments of this application, the bracket includes a plurality of mounting units, which are installed at intervals along the longitudinal direction of the vehicle frame, and a space for housing a battery is formed between two adjacent mounting units.

[0080] In the above solution, by installing multiple mounting units on a bracket in the longitudinal direction of the vehicle frame, multiple spaces can be formed to accommodate the battery, reducing the risk of wasted space due to the battery occupying external space. In some embodiments, when the battery is arranged along the longitudinal direction of the vehicle frame, multiple batteries can be arranged in the transverse direction of the vehicle frame, and the space formed by multiple mounting units on a single vehicle frame can accommodate at least one row of batteries together. In some embodiments, when the battery is arranged along the transverse direction of the vehicle frame, two batteries can be arranged. bracket They can be installed together.

[0081] According to some embodiments of this application, the vehicle frame further includes a cross member connected between a pair of side members. The cross member is provided with a second mounting portion that is detachably connected to a battery.

[0082] In the above solution, by installing a second mounting portion on the cross member, a mounting point is provided between the battery and the cross member, improving the connection stability between the battery and the vehicle body and reducing the risk of the battery falling out. In some embodiments, when the batteries are arranged along the longitudinal direction of the vehicle frame, multiple batteries can be arranged along the transverse direction of the vehicle frame, and by installing a second mounting portion on the cross member, at least one row of batteries can be mounted at corresponding positions on the cross member. In some embodiments, when the batteries are arranged along the transverse direction of the vehicle frame, two batteries can be arranged bracket It can be mounted together by the upper first mounting section and the mounting section on the cross member.

[0083] According to some embodiments of this application, the bracket assembly further includes a reinforcing plate connected to a cross member, the reinforcing plate having through holes corresponding to a second mounting portion.

[0084] In the above plan, by installing the reinforcing plate, the structural strength of the cross member can be effectively improved, the risk of damage to the cross member due to the mounting of the battery can be reduced, and the connection stability between the cross member and the battery can be improved.

[0085] According to some embodiments of this application, the mounting beam is a square pipe.

[0086] In the above-described method, by installing the mounting beam on a square pipe, material costs are low, while the strength of the material structure is high, allowing for effective battery mounting and reducing the risk of battery detachment.

[0087] According to some embodiments of this application, the projection of the bracket and the projection of the vehicle body frame overlap at least partially along the lateral direction of the vehicle body frame.

[0088] In the direction described above, the lateral direction of the vehicle frame is perpendicular to the vehicle body. Direction Even if this is the case, by positioning the bracket so that its projection at least partially overlaps with the projection of the vehicle frame, the gap between the bracket and the ground can be effectively improved, reducing the impact of the bracket's mounting on the vehicle body's ground clearance and improving the vehicle's driving reliability.

[0089] According to some embodiments of this application, the bracket has an upward-opening relief groove, and at least a portion of the vehicle frame is accommodated in the relief groove.

[0090] In the above-described method, by installing a relief groove in the bracket, at least a portion of the vehicle frame is provided as clearance, the space where at least a portion of the vehicle frame is located is rationally utilized, and the installation of the bracket reduces the impact on the gap between the vehicle body and the ground.

[0091] According to some embodiments of this application, the vehicle frame is connected to the bottom wall and / or side wall of the relief groove.

[0092] In the above solution, since at least a portion of the vehicle frame is housed in the relief groove, the vehicle frame can be connected to the bottom wall and / or side walls of the relief groove, allowing for rational use of the relief groove. This not only allows the relief groove to clear the bracket, but also enables connection between the bracket and the vehicle frame, simplifying the connection structure between the bracket and the vehicle frame, reducing the difficulty of installation, and lowering installation costs.

[0093] According to some embodiments of this application, the first connector is attached to a bracket assembly.

[0094] In the above solution, by attaching the first connector to the bracket assembly, the first and second connectors are simultaneously aligned when the battery is attached to the bracket assembly, thereby improving power exchange efficiency.

[0095] According to some embodiments of this application, the vehicle body includes a cargo compartment, and the bracket assembly is located below the cargo compartment.

[0096] In the above plan, the vehicle body may be a vehicle body having the nature of cargo transport, and it may include a container for loading cargo. For example, the vehicle body may be the vehicle body of a heavy truck. By installing the bracket assembly below the container, the space below the container can be used rationally, and compared to the current backpack-type power exchange of heavy trucks (the battery is mounted behind the driver's cab of the heavy truck), the battery location layout of the vehicle body can be changed, space in the longitudinal direction of the vehicle can be effectively saved, the space occupied by the container can be reduced, and the vehicle's load capacity can be improved.

[0099] According to some embodiments of this application, the battery has clearance space to accommodate the bracket assembly.

[0100] In the above solution, by providing clearance space for the battery, the space where the bracket assembly is located can be rationally utilized, improving the battery's electrical capacity and providing the vehicle with a longer driving range.

[0101] According to some embodiments of this application, the bracket assembly includes a vehicle frame. Along the lateral direction of the vehicle frame, the projection of the battery and the projection of the vehicle frame overlap at least partially.

[0102] In the above plan, the lateral direction of the vehicle frame may be perpendicular to the vehicle's direction of travel, or it may be understood as the vehicle's width direction. By positioning the battery along the lateral direction of the vehicle frame such that its projection and the projection of the vehicle frame at least partially overlap, the battery can make rational use of the vehicle's height space, improving its electrical capacity and providing the vehicle with a longer range.

[0103] According to some embodiments of this application, the bracket assembly includes a vehicle frame. The battery includes a housing and a plurality of battery cells installed within the housing, and along the lateral direction of the vehicle frame, the projection of at least some of the battery cells overlaps with the projection of the vehicle frame.

[0104] In the above plan, the lateral direction of the vehicle frame may be perpendicular to the direction of travel of the vehicle, or it may be understood as the width direction of the vehicle. By aligning at least some of the battery cells in the battery along the lateral direction of the vehicle frame such that the projection of the battery overlaps with the projection of the vehicle frame at least partially, the height space of the vehicle body can be rationally utilized for these at least some of the battery cells, improving the electrical capacity of the battery and providing the vehicle with a longer range.

[0105] According to some embodiments of this application, the lowest point of the battery is the bracket assembly It is lower than the lowest score.

[0106] In the above plan, the lowest point of the battery is the bracket assembly By setting the minimum point lower than the minimum, the battery can make rational use of the vehicle's height space, improving the battery's electrical capacity and providing the vehicle with a longer driving range.

[0107] According to some embodiments of this application, the vehicle is a heavy truck.

[0108] Heavy trucks may also be heavy-duty trucks, and the required battery capacity varies depending on the type of cargo transport or transport route (for example, one battery is needed for short distances, two batteries for medium distances, and three batteries for long distances). The vehicle body provided above allows for power exchange as needed (for example, only one battery is needed for short distances, i.e., one battery is installed; only two batteries are needed for medium distances, i.e., two batteries are installed; and three batteries are needed for long distances, i.e., three batteries are installed), thereby saving the cost of extra batteries and effectively reducing power exchange costs.

[Modes for carrying out the invention]

[0111] To clarify the purpose, technical proposal, and advantages of the embodiments of this application, the following clearly and completely describes the technical proposal of the embodiments of this application, linking it with the drawings of the embodiments. Clearly, the embodiments described are only some, not all, embodiments of this application. All other embodiments derived from the embodiments of this application without the creative effort of a person skilled in the art are all within the scope of protection of this application.

[0112] Unless otherwise defined, all technical and scientific terms used in this application have the same meaning as that generally understood by those skilled in the art relating to this application. The terms used in the specification of this application are solely for the purpose of describing specific embodiments and are not intended to limit this application. The terms “includes” and “have,” and any variations thereof, in the description of the specification, claims, and drawings of this application are intended to intentionally cover non-exclusive “includes.” Terms such as “first,” “second,” etc., in the specification, claims, or drawings of this application are not intended to describe a particular order or hierarchical relationship, but are intended to distinguish different subjects.

[0113] The “Examples” as used in this application mean that certain features, structures, or characteristics described in conjunction with the Examples may be included in at least one Example of this application. The appearance of this phrase at each location in the specification does not necessarily refer to the same Example, nor does it mean that each Example is mutually exclusive or alternative to the others. Those skilled in the art will understand, both explicitly and implicitly, that the Examples described in this application may be combined with other Examples.

[0114] In the description of this application, unless otherwise specifically defined or limited, the terms “attachment,” “connection,” “connection,” and “installation” should be understood in a broad sense. For example, a fixed connection may be a detachable connection, an integral connection, a direct connection, an indirect connection via an intermediate medium, or internal communication between two elements. A person skilled in the art will be able to understand the specific meaning of these terms in this application depending on the specific circumstances.

[0115] In this application, the terms "and / or" merely describe the relationship between related objects, indicating that three relationships are possible. For example, A and / or B may represent three cases: A alone, a combination of A and B, and B alone. In this application, the character " / " generally indicates that the preceding and succeeding related objects are in an "or" relationship.

[0116] In this application, "multiple" refers to two or more (including two), similarly, "multiple sets" refers to two or more sets (including two sets), and "multiple sheets" refers to two or more sheets (including two sheets).

[0117] In some embodiments, the battery may be a battery module, and if there are multiple battery cells, the multiple battery cells are fixed side by side to form a single battery module.

[0118] In some embodiments, the battery may be a battery pack, which includes a housing and battery cells, and the battery cells or battery modules are housed in the housing.

[0119] In some embodiments, the battery cell may be a secondary battery, which is a battery cell that can be used continuously by activating the active material through charging after discharge. The battery cell may be a lithium-ion battery, sodium-ion battery, sodium-lithium-ion battery, lithium metal battery, sodium metal battery, lithium-sulfur battery, magnesium-ion battery, nickel-metal hydride battery, nickel-cadmium battery, lead-acid battery, etc., and the embodiments of this application are not limited thereto.

[0120] Currently, new energy vehicles (NEVs) constantly replenish their power losses during operation through a power swapping system. For NEVs, reducing power swapping costs is an urgent technological issue that needs to be resolved. Currently, NEVs are configured with a single monoblock battery with a fixed electrical capacity, meaning the vehicle's range is fixed, and this single monoblock battery is replaced during power swapping. However, the required battery capacity varies depending on the range demands; for example, a relatively short range requires only a relatively small battery. Configuring a relatively large battery incurs additional battery costs due to the extra electrical capacity, and furthermore, power swapping costs are relatively high.

[0121] Therefore, in order to solve the problem of high power exchange costs due to differences in range demand, some embodiments of this application provide a vehicle body which includes a bracket assembly and a plurality of first connectors. The bracket assembly is used to detachably connect to a corresponding number of batteries by providing a plurality of sets of first mounting parts. The plurality of first connectors are used to connect to second connectors of a corresponding number of batteries by providing a plurality of first connectors.

[0122] In the above-described solution, by installing multiple sets of first mounting units and multiple first connectors, the number of batteries that need to be replaced can be adjusted according to the range demand (that is, power can be replaced as needed; for example, if the required range is relatively short, a relatively small number of batteries can be mounted in the corresponding number of first mounting units in the multiple sets of first mounting units, and the second connector of each battery is connected to the corresponding first connector; if the required range is relatively long, a relatively large number of batteries can be mounted in the corresponding number of first mounting units in the multiple sets of first mounting units, and the second connector of each battery is connected to the corresponding first connector), thereby saving the cost of extra batteries and effectively reducing the cost of power replacement.

[0123] The vehicle bodies disclosed in the embodiments of this application may be used for passenger vehicles, commercial freight vehicles, and vehicles of other natures, and are not limited thereto.

[0124] Referring to Figure 1, Figure 1 is a schematic diagram of the structure of vehicle 10000 according to some embodiments of the present application. Vehicle 10000 may be a new energy vehicle, which may be a pure electric vehicle, a power-swappable hybrid vehicle, or a power-swappable range extender vehicle. Vehicle 10000 includes a vehicle body 1000 and a battery 2000. In the battery 2000, the battery 2000 may be installed at the bottom, head, or tail of the vehicle body 1000. The battery 2000 may be used to supply power to vehicle 10000, for example, as an operating power source for vehicle 10000, used in the circuit system of vehicle 10000, for example, to start up vehicle 10000, navigation, and to meet the operating power consumption requirements during operation.

[0125] The vehicle body 1000 may further include a controller 3000 and a motor 4000, the controller 3000 being used to control the battery 2000 to supply power to the motor 4000, and the motor being used, for example, to meet the power consumption requirements for starting the vehicle 10000, navigation, and driving.

[0126] In some embodiments of this application, the battery 2000 can provide driving power to the vehicle 10000 not only as an operating power source for the vehicle 10000, but also as a driving power source for the vehicle 10000, in place of or in part of fuel oil or natural gas.

[0127] Some embodiments of this application provide a vehicle body 1000, and referring to Figures 2 and 3, Figure 2 shows a plan view of the local structure of the vehicle body 1000 in some embodiments of this application. Figure 3 is a schematic diagram of a bracket assembly 100 and a battery 2000 in some embodiments of this application.

[0128] The vehicle body 1000 includes a bracket assembly 100 and a plurality of first connectors 200. The bracket assembly 100 is fitted with a plurality of sets of first mounting parts 300, each set of first mounting parts 300 is used to detachably connect to a single battery 2000, the number of first connectors 200 is equal to the number of sets of first mounting parts 300, and each first connector 200 is used to connect to a second connector of a single battery 2000.

[0129] The bracket assembly 100 is an assembly for mounting the battery 2000. In the vehicle body 1000, the bracket assembly 100 may be installed at any of the locations on the vehicle body 1000. For example, the bracket assembly 100 may be used at the rear of the driver's cab of the vehicle body 1000, at the front of the vehicle body 1000, at the rear of the vehicle body 1000, or at the bottom of the vehicle body 1000.

[0130] In some embodiments, the bracket assembly 100 is the main structure that enables the vehicle body 1000 to perform power exchange. The first mounting portion 300 is installed on the bracket assembly 100 and is a component for detachably connecting to the battery 2000. The first mounting portion 300 is installed in sets, and each set of the first mounting portion 300 corresponds to one battery 2000 and is used to detachably attach the corresponding battery 2000 to the bracket assembly 100. Multiple sets of the first mounting portion 300 are installed on the bracket assembly 100, meaning that the bracket assembly 100 can detachably connect to a corresponding number of batteries 2000 by multiple sets of the first mounting portion 300, thereby enabling power exchange of multiple batteries 2000. In some embodiments, the first mounting portion 300 includes, but is not limited to, mounting holes, mounting screws, and other structures that enable detachable connection to the battery 2000. In some embodiments, the number of sets of the first mounting portions 300 of the bracket assembly 100 may be two, three, four or more.

[0131] In some embodiments, the first connector 200 is a component connected to a second connector of a battery 2000, and one first connector 200 is used to connect to the second connector of one battery 2000. In some embodiments, the first connector 200 may include, but is not limited to, a high / low voltage connector for connecting to the battery 2000 or a liquid-cooled connector for connecting to the battery 2000. In some embodiments, the high / low voltage connector is electrically connected to the battery 2000 and can realize input or output to the battery 2000 and input or output of electrical signals. The liquid-cooled connector is used for input or output of the heat exchange medium of the battery 2000 to thermally manage the battery 2000.

[0132] The statement that "the number of first connectors 200 is equal to the number of sets of first mounting parts 300" means that the vehicle body 1000 can exchange power as needed, and regardless of the number of batteries 2000 mounted on the bracket assembly 100 by the first mounting parts 300, each battery 2000 can be connected to its corresponding first connector 200, thereby allowing each battery 2000 to operate and be charged and discharged normally. For example, the range requirements of the vehicle 10000 can be divided into short-range range requirements, medium-range range requirements, and long-range range requirements. Since the short-range range requirement may correspond to one battery 2000, the medium-range range requirement to two batteries 2000, and the long-range range requirement to three batteries 2000, the bracket assembly 100 may be equipped with three sets of first mounting parts 300, allowing at most three batteries 2000 to be mounted and the longest range requirement to be met. If short-range range requirements need to be met, only one battery 2000 can be mounted, and the second connector of this single battery 2000 is connected to one first connector 200. If medium-range range requirements need to be met, only two batteries 2000 can be mounted, and the second connectors of these two batteries 2000 are each connected to two first connectors 200. If long-range range requirements need to be met, three batteries 2000 can be mounted, and the second connector of each battery 2000 is connected to the corresponding first connector 200.

[0133] In the above solution, the vehicle body 1000 includes a bracket assembly 100 and a plurality of first connectors 200. By installing a plurality of first connectors 200 and a plurality of first mounting parts 300 on the bracket assembly 100, the number of batteries 2000 that need to be replaced can be adjusted according to the range demand (that is, the power can be replaced as needed; for example, if the required range is relatively short, a relatively small number of batteries 2000 can be mounted on the corresponding number of first mounting parts 300 in the plurality of first mounting parts 300, and the second connector of each battery 2000 can be connected to the corresponding first connector 200; if the required range is relatively long, a relatively large number of batteries 2000 can be mounted on the corresponding number of first mounting parts 300 in the plurality of first mounting parts 300, and the second connector of each battery 2000 can be connected to the corresponding first connector 200), thereby saving the cost of extra batteries 2000 and effectively reducing the cost of power replacement.

[0134] According to some embodiments of this application, the bracket assembly 100 includes a vehicle body frame 20.

[0135] In some embodiments, the vehicle frame 20 may be a framework structure spanning the front and rear axles of the vehicle body 1000, commonly referred to as a girder, and is the base of the vehicle body 1000. The role of the vehicle frame 20 may include supporting and connecting the vehicle body 1000, keeping each assembly in the correct relative position, and bearing various loads inside and outside the vehicle body 1000.

[0136] In some embodiments, the vehicle frame 20 is located at the bottom of the vehicle body 1000.

[0137] In the above plan, the first mounting section 300 may be installed on the vehicle frame 20, allowing the battery 2000 to be stably mounted, improving the connection stability between the battery 2000 and the vehicle body 1000, and reducing the risk of the battery 2000 falling off. Furthermore, because the vehicle frame 20 is located at the bottom of the vehicle body 1000, the battery 2000 can be powered from below the vehicle body 1000. Compared to the current backpack-type power exchange of heavy trucks (where the battery 2000 is mounted behind the driver's cab of the heavy truck), this changes the positional layout of the battery 2000 on the vehicle body 1000, effectively saving space in the longitudinal direction of the vehicle 10000 and improving the load capacity of the vehicle 10000.

[0138] According to some embodiments of this application, referring to Figures 2 and 3, the bracket assembly 100 further includes a bracket 10 that is fixedly connected to the vehicle body frame 20, the bracket 10 having a first mounting portion 300 installed thereon.

[0139] The bracket 10 is a component fixed to the vehicle frame 20. In some embodiments, the bracket 10 can be connected to the vehicle frame 20 by welding, riveting, screwing, etc. In some other embodiments, the bracket 10 can be manufactured by integral molding with the vehicle frame 20.

[0140] The bracket 10 is provided with a first mounting portion 300 on which the battery 2000 can be mounted. In some embodiments, the bracket 10 has a certain structural strength to support the mounting of the battery 2000. In some embodiments, the material of the bracket 10 may be the same as the material of the vehicle frame 20. In some embodiments, the material of the bracket 10 may be aluminum alloy, steel, cast iron, or reinforced plastic.

[0141] In the above solution, by permanently connecting the bracket 10 to the vehicle frame 20, the impact of the installation of the bracket 10 on the structural reliability of the vehicle body 1000 can be reduced, while the bracket 10 can be stably attached to the vehicle body 1000 and the battery 2000 can be effectively mounted. On the other hand, the bracket 10 can be retrofitted to the existing vehicle body 1000's vehicle frame 20, making retrofitting easier, faster, and allowing the existing vehicle 10000 to quickly acquire the function of exchanging power as needed.

[0142] Referring to Figure 4, which is a front view of a bracket assembly 100 and a battery 2000 in some embodiments of this application.

[0143] The vehicle frame 20 includes a first side member 21 and a second side member 22. The highest point of the bracket 10 is below the upper end surface of the first side member 21, and the highest point of the bracket 10 is below the upper end surface of the second side member 22.

[0144] In some embodiments, the vehicle body 1000 can be applied to a commercial truck (e.g., a heavy truck) or a passenger car (e.g., a large bus), and the vehicle frame 20 may include a first side member 21 and a second side member 22. The first side member 21 and the second side member 22 may be installed facing each other with a gap between them, and the direction of the gap between the first side member 21 and the second side member 22 may be the width direction of the vehicle body 1000, and the direction in which the first side member 21 and the second side member 22 extend may be the longitudinal direction of the vehicle body 1000.

[0145] The statement "the highest point of bracket 10 is below the upper end surface of the first side member 21" can be understood as meaning that, along the height direction (the direction perpendicular to the ground, generally the direction in which the vehicle 10000 travels on the ground), the part of bracket 10 furthest from the ground is below the part of the first side member 21 furthest from the ground, that is, no part of bracket 10 exceeds the first side member 21. The statement "the highest point of bracket 10 is below the upper end surface of the second side member 22" can be understood as meaning that, along the height direction, the part of bracket 10 furthest from the ground is below the part of the second side member 22 furthest from the ground, that is, no part of bracket 10 exceeds the second side member 22.

[0146] In the above solution, the vehicle frame 20 may include a first side member 21 and a second side member 22 in the girder. For example, the vehicle frame 20 may include a first side member 21 and a second side member 22 in the girder of a large vehicle 10000 (e.g., a heavy truck). By installing the bracket 10 on the vehicle frame 20 and ensuring that it does not extend beyond the upper end surfaces of the first side member 21 and the second side member 22, interference of the bracket 10 into the interior of the vehicle body 1000 due to its installation can be reduced without occupying the space above the first side member 21 and the second side member 22. On the other hand, if the bracket 10 is retrofitted to the current vehicle body 1000, the difficulty of reinforcing the bracket 10 is low and the feasibility of implementation is high. On the other hand, if the battery 2000 is attached to the bracket 10 or to the first side member 21 and the second side member 22, the battery 2000 can perform power exchange from below the vehicle body 1000. Compared to the current backpack-type power exchange of heavy trucks (the battery 2000 is attached to the back of the driver's cab of the heavy truck), this changes the positional layout of the battery 2000 in the vehicle body 1000, effectively saving space in the longitudinal direction of the vehicle 10000 and improving the load capacity of the vehicle 10000.

[0147] In some embodiments of this application, referring to Figures 3 and 4, the bracket 10 extends beyond the second side member 22, along the direction in which the first side member 21 is toward the second side member 22.

[0148] In some embodiments, the direction in which the first side member 21 faces the second side member 22 may be parallel to the width direction of the vehicle body 1000, that is, perpendicular to the direction of travel of the vehicle 10000.

[0149] The statement "the bracket 10 extends beyond the second side member 22 in the direction toward the first side member 21" may be understood as the portion of the bracket 10 being on the side of the second side member 22 away from the first side member 21, or as the portion of the bracket 10 being on the outside of the vehicle frame 20.

[0150] In the above solution, by installing the bracket 10 so as to extend beyond the second side member 22, a larger mounting position can be provided for the battery 2000, thereby allowing for the replacement of more batteries 2000 or batteries 2000 with larger volumes to adapt to the range requirements of different vehicles 10000 or different range requirements of the vehicle 10000.

[0151] In some other embodiments, the bracket 10 does not have to extend beyond the second side member 22; for example, the bracket 10 is located between the first side member 21 and the second side member 22.

[0152] According to some embodiments of this application, referring to Figure 3, at least one first mounting portion 300 is provided on the portion of the bracket 10 that extends beyond the second side member 22.

[0153] The statement "at least one first mounting portion 300 is installed on the portion of the bracket 10 beyond the second side member 22" may be understood as at least one of a pair or each pair of first mounting portions 300 being installed on the portion of the bracket 10 beyond the second side member 22. In some embodiments, multiple first mounting portions 300 may be installed on the portion of the bracket 10 beyond the second side member 22, and these multiple first mounting portions 300 are first mounting portions 300 of multiple pairs of first mounting portions 300. In some embodiments, multiple first mounting portions 300 may be installed on the portion of the bracket 10 beyond the second side member 22, and these multiple first mounting portions 300 are first mounting portions 300 of a pair of mounting portions. In some embodiments, one first mounting portion 300 may be installed on the portion of the bracket 10 beyond the second side member 22, and this one first mounting portion 300 is first mounting portion 300 of a pair of mounting portions. In some embodiments, one of the first mounting portions 300 of each set may be mounted on a portion of the bracket 10 that extends beyond the second side member 22.

[0154] In the above solution, by installing at least one first mounting portion 300 on the portion of the bracket 10 that extends beyond the second side member 22, the battery 2000 can be stably connected to the bracket 10 by connecting it to the portion of the battery 2000 that extends beyond the second side member 22, thereby improving the structural stability of the battery 2000 and the bracket 10.

[0155] According to some embodiments of this application, the bracket 10 extends beyond the first side member 21, with the second side member 22 moving toward the first side member 21.

[0156] In some embodiments, the direction in which the second side member 22 faces the first side member 21 may be parallel to the width direction of the vehicle body 1000, that is, perpendicular to the direction of travel of the vehicle 10000.

[0157] The statement "the bracket 10 extends beyond the first side member 21 in the direction toward the second side member 22" may be understood as the portion of the bracket 10 being on the side of the first side member 21 away from the second side member 22, or as the portion of the bracket 10 being on the outside of the vehicle frame 20.

[0158] In the above solution, by installing the bracket 10 so as to extend beyond the first side member 21, a larger mounting position can be provided for the battery 2000, thereby allowing for the replacement of more batteries 2000 or batteries 2000 with larger volumes to adapt to the range requirements of different vehicles 10000 or different range requirements of the vehicle 10000.

[0159] In some other embodiments, the bracket 10 does not have to extend beyond the first side member 21; for example, a portion of the bracket 10 is located between the first side member 21 and the second side member 22, and a portion of the bracket 10 extends beyond the second side member 22.

[0160] According to some embodiments of this application, referring to Figure 3, at least one first mounting portion 300 is provided on the portion of the bracket 10 that extends beyond the first side member 21.

[0161] The statement "at least one first mounting portion 300 is installed on the portion of the bracket 10 beyond the first side member 21" may be understood as at least one of a set of first mounting portions 300 or each set of first mounting portions 300 being installed on the portion of the bracket 10 beyond the first side member 21. In some embodiments, multiple first mounting portions 300 may be installed on the portion of the bracket 10 beyond the first side member 21, and these multiple first mounting portions 300 are first mounting portions 300 of multiple sets of first mounting portions 300. In some embodiments, multiple first mounting portions 300 may be installed on the portion of the bracket 10 beyond the first side member 21, and these multiple first mounting portions 300 are first mounting portions 300 of a set of mounting portions. In some embodiments, one first mounting portion 300 may be installed on the portion of the bracket 10 beyond the first side member 21, and this one first mounting portion 300 is first mounting portion 300 of a set of mounting portions. In some embodiments, one of the first mounting portions 300 of each set may be mounted on a portion of the bracket 10 that extends beyond the first side member 21.

[0162] In the above solution, by installing at least one first mounting portion 300 on the portion of the bracket 10 that extends beyond the first side member 21, the battery 2000 can be stably connected to the bracket 10 by connecting it to the portion of the battery 2000 that extends beyond the first side member 21, thereby improving the structural stability of the battery 2000 and the bracket 10.

[0163] According to some embodiments of this application, at least a portion of the bracket 10 is located between the first side member 21 and the second side member 22.

[0164] In some embodiments, the statement "at least a portion of the bracket 10 is located between the first side member 21 and the second side member 22" may be understood as meaning that a portion of the bracket 10 is located between the first side member 21 and the second side member 22, that is, a portion of the bracket 10 may be outside the first side member 21 and / or the second side member 22, or the entire bracket 10 may be understood as being located between the first side member 21 and the second side member 22.

[0165] In the above solution, the center of gravity of the vehicle body 1000 may be located between the first side member 21 and the second side member 22. Therefore, by installing at least a part of the bracket 10 between the first side member 21 and the second side member 22, the influence of the bracket 10 on the center of gravity of the vehicle body 1000 can be reduced, thereby improving the driving stability of the vehicle body 1000. On the other hand, when the battery 2000 is attached to the bracket 10, part or a portion of the battery 2000 may be located between the first side member 21 and the second side member 22, thus reducing the influence of the battery 2000 on the center of gravity of the vehicle body 1000 and improving the driving stability of the vehicle body 1000.

[0166] In some other embodiments, the bracket 10 does not have to be located between the first side member 21 and the second side member 22. For example, the bracket 10 may be installed on the side of the first side member 21 away from the second side member 22, or on the side of the second side member 22 away from the first side member 21, or there may be two brackets 10, one of which may be installed on the side of the first side member 21 away from the second side member 22, and the other bracket 10 may be installed on the side of the second side member 22 away from the first side member 21.

[0167] According to some embodiments of this application, referring to Figure 2, at least one first mounting portion 300 is provided on the portion of the bracket 10 located between the first side member 21 and the second side member 22.

[0168] In some embodiments, the number of first mounting portions 300 installed on the portion of the bracket located between the first side member 21 and the second side member 22 may be one, two, three or more.

[0169] The statement "At least one first mounting portion 300 is installed on the portion of the bracket 10 located between the first side member 21 and the second side member 22" may be understood as at least one of a pair or each pair of first mounting portions 300 being installed on the portion of the bracket 10 located between the first side member 21 and the second side member 22. In some embodiments, multiple first mounting portions 300 may be installed on the portion of the bracket 10 located between the first side member 21 and the second side member 22, and these multiple first mounting portions 300 are first mounting portions 300 of multiple pairs of first mounting portions 300. In some embodiments, multiple first mounting portions 300 may be installed on the portion of the bracket 10 located between the first side member 21 and the second side member 22, and these multiple first mounting portions 300 are first mounting portions 300 of a pair of mounting portions. In some embodiments, a first mounting portion 300 may be installed on the portion of the bracket 10 located between the first side member 21 and the second side member 22, and this first mounting portion 300 is the first mounting portion 300 of a set of mounting portions. In some embodiments, one of the first mounting portions 300 of each set of first mounting portions 300 may be installed on the portion of the bracket 10 located between the first side member 21 and the second side member 22.

[0170] In the above solution, by installing at least one first mounting portion 300 in the part of the bracket 10 located between the first side member 21 and the second side member 22, and connecting it to the part of the battery 2000 located between the first side member 21 and the second side member 22, the battery 2000 can be stably connected to the bracket 10, thereby improving the structural stability of the battery 2000 and the bracket 10.

[0171] Referring to Figure 5, which is a schematic diagram of a bracket assembly 100 in some other embodiments of this application,

[0172] The vehicle frame 20 is equipped with a second mounting section 301 for detachably connecting to the battery 2000.

[0173] The second mounting portion 301 is installed on the vehicle frame 20 and is a component for detachably connecting to the battery 2000. In some embodiments, the second mounting portion 301 includes, but is not limited to, mounting holes, mounting screws, and other structures that enable detachable connection to the battery 2000. In some embodiments, the second mounting portion 301 may have the same structure as the first mounting portion 300.

[0174] In some embodiments, multiple sets of second mounting parts 301 may be installed on the vehicle frame 20, and the number of sets of second mounting parts 301 corresponds to the number of sets of first mounting parts 300, so that each battery 2000 can be connected by one set of first mounting parts 300 and one set of second mounting parts 301.

[0175] In the above-described solution, a second mounting portion 301 is installed on the vehicle frame 20 and detachably connected to the battery 2000, and by fitting it into the first mounting portion 300 and detachably connecting it to the battery 2000, the connection stability between the battery 2000 and the vehicle body 1000 can be improved, thereby improving the reliability of the vehicle body 1000's operation.

[0176] According to some embodiments of this application, the vehicle frame 20 includes a first side member 21 and a second side member 22, and the second mounting portion 301 is installed on the first side member 21 and / or the second side member 22.

[0177] In some embodiments, the vehicle body 1000 can be applied to a commercial truck (e.g., a heavy truck) or a passenger car (e.g., a large bus), and the vehicle frame 20 may include a first side member 21 and a second side member 22.

[0178] In some embodiments, the second mounting portion 301 may be mounted on the first side member 21. In some embodiments, the second mounting portion 301 may be mounted on the second side member 22. In some embodiments, the second mounting portion 301 may be mounted on both the first side member 21 and the second side member 22.

[0179] In the above solution, the vehicle frame 20 may include a first side member 21 and a second side member 22 in the girder. For example, the vehicle frame 20 may include a first side member 21 and a second side member 22 in the girder of a large vehicle 10000 (e.g., a heavy truck). By installing the second mounting portion 301 on the first side member 21 and / or the second side member 22, and effectively fitting it with the first mounting portion 300, the battery 2000 can be effectively connected to the vehicle body 1000, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle body 1000.

[0180] According to some embodiments of this application, the vehicle frame 20 includes a first side member 21, a second side member 22, and a cross member 23 connected between the first side member 21 and the second side member 22, and the second mounting portion 301 is installed on the cross member 23.

[0181] In some embodiments, the first side member 21 and the second side member 22 are installed opposite each other with a gap between them, and the cross member 23 is located in the gap formed by the gap between the first side member 21 and the second side member 22, and the cross member 23 is connected to the first side member 21 and the second side member 22. The cross member 23 improves the structural strength of the vehicle frame 20, so that the vehicle frame 20 can effectively withstand various loads inside and outside the vehicle body 1000.

[0182] In the above plan, the vehicle frame 20 may include a first side member 21, a second side member 22, and a cross member 23 in the girder. For example, the vehicle frame 20 may include a first side member 21, a second side member 22, and a cross member 23 in the girder of a large vehicle 10000 (e.g., a heavy truck). By installing the second mounting portion 301 on the cross member 23, it can be effectively fitted with the first mounting portion 300, thereby effectively connecting the battery 2000 to the vehicle body 1000, reducing the risk of the battery 2000 falling off, and improving the driving reliability of the vehicle body 1000. On the other hand, since the cross member 23 is located in the gap formed between the first side member 21 and the second side member 22, by installing the second mounting portion 301 on the cross member 23, the space between the first side member 21 and the second side member 22 can be rationally utilized, reducing interference of the second mounting portion 301 with the bracket 10, and improving the power exchange efficiency of the vehicle body 1000.

[0183] According to some embodiments of this application, referring to Figures 2 and 3, the bracket assembly 100 has a plurality of housing spaces 100a, which are arranged along a first direction, and each housing space 100a is used to house one battery 2000, and a pair of first mounting parts 300 are installed correspondingly in each housing space 100a.

[0184] In some embodiments, the bracket assembly 100 has a plurality of housing spaces 100a aligned along a first direction, and the plurality of housing spaces 100a are independent of each other. Each housing space 100a may be used to house one battery 2000, and the battery 2000 located in the housing space 100a may be connected by a set of first mounting parts 300 in the housing space 100a.

[0185] The arrangement of multiple storage spaces 100a along a first direction may be understood as the arrangement of multiple batteries 2000 along a first direction.

[0186] In some embodiments, the size of the housing space 100a may be the same so that the bracket assembly 100 can accommodate multiple batteries 2000 of the same specifications. In some other embodiments, the size of the housing space 100a may be different so that the bracket assembly 100 can accommodate multiple batteries 2000 of different specifications.

[0187] In the above-described solution, multiple storage spaces 100a are provided in the first direction, and a pair of first mounting parts 300 are provided in each storage space 100a. This allows each battery 2000 to be neatly mounted in its corresponding storage space 100a, preventing interference between the batteries 2000 and improving the power exchange efficiency of the vehicle body 1000.

[0188] According to some embodiments of this application, referring to Figure 3, the housing space 100a has an opening that opens downward, and the opening is used for the battery 2000 to enter and exit the housing space 100a.

[0189] The phrase "the accommodation space 100a has an opening that opens downwards" may be understood as the accommodation space 100a having an opening that faces the ground, and for example, if a vehicle 10000 is supported on the ground, the opening of the accommodation space 100a faces the ground.

[0190] In some embodiments, the battery 2000 can enter and exit the housing space 100a through the opening.

[0191] In some embodiments, a trench may be installed at the power exchange location, and the electrical exchange mechanism may be installed in the trench, and when the vehicle body is at the power exchange location, the trench may be located below the vehicle body, and the battery 2000 enters and exits the storage space 100a by the electrical exchange mechanism in the trench.

[0192] In the above-described solution, by installing an opening that opens downwards, the battery 2000 can easily enter and exit the storage space 100a from below the vehicle body 1000. Compared to the current backpack-type power exchange solution for heavy trucks, this saves space above the vehicle frame 20 and reduces the risk of damage to the vehicle body 1000 due to interference with the vehicle body 1000 caused by the space above the vehicle frame 20 during power exchange by the electrical exchange mechanism. At the same time, it changes the positional layout of the battery 2000 on the vehicle body 1000, effectively saving space in the longitudinal direction of the vehicle 10000 and improving the load capacity of the vehicle 10000.

[0193] According to some embodiments of this application, referring to Figure 3, the first direction is parallel to the longitudinal direction y of the vehicle frame.

[0194] The first direction is the orientation of the housing space 100a, which may also be understood as the orientation of the batteries 2000.

[0195] The longitudinal direction y of the vehicle frame may be the direction in which the side members of the vehicle frame 20 extend, or the longitudinal direction y of the vehicle frame may be the direction of travel of the vehicle 10000.

[0196] In some embodiments, referring to Figure 3, the battery 2000 may be elongated, and if the first direction is parallel to the longitudinal direction y of the vehicle frame, the longitudinal direction of the battery 2000 may be perpendicular to the first direction, that is, the longitudinal direction of the battery 2000 may be parallel to the lateral direction x of the vehicle frame. The lateral direction x of the vehicle frame may be the direction of the arrangement of a pair of side members in the vehicle frame 20, and the lateral direction x of the vehicle frame may be the width direction of the vehicle 10000. Referring to Figure 3, the three batteries 2000 are arranged along the longitudinal direction y of the vehicle frame.

[0197] In the above plan, the longitudinal direction y of the vehicle frame may be parallel to the direction of travel of the vehicle body 1000, or the longitudinal direction y of the vehicle frame may be the direction in which the side members of the vehicle frame 20 extend. By aligning the first direction parallel to the longitudinal direction y of the vehicle frame, that is, by aligning the multiple batteries 2000 along the longitudinal direction y of the vehicle frame, the center of gravity of the batteries 2000 is brought closer to the center on the lateral direction x of the vehicle frame, reducing the influence of the battery 2000 mounting on the center of gravity of the vehicle body 1000, and enabling the vehicle body 1000 to have relatively high driving reliability.

[0198] According to some embodiments of this application, referring to Figure 2, the vehicle frame 20 includes a first side member 21 and a second side member 22, and each accommodation space 100a is partitioned by the first side member 21 and the second side member 22 into a first sub-space 100b, a second sub-space 100c and a third sub-space 100d, the first sub-space 100b is located between the first side member 21 and the second side member 22, the second sub-space 100c is located on the side of the first side member 21 away from the second side member 22, and the third sub-space 100d is located on the side of the second side member 22 away from the first side member 21.

[0199] In some embodiments, the vehicle body 1000 can be applied to a commercial truck (e.g., a heavy truck) or a passenger car (e.g., a large bus), and the vehicle frame 20 may include a first side member 21 and a second side member 22. The first side member 21 and the second side member 22 may be installed opposite each other with a gap between them, and the direction of the gap between the first side member 21 and the second side member 22 may be the width direction of the vehicle body 1000 or the lateral direction x of the vehicle frame, and the direction in which the first side member 21 and the second side member 22 extend may be the longitudinal direction of the vehicle body 1000.

[0200] In some embodiments, the accommodation space 100a is divided into three subspaces by a first side member 21 and a second side member 22, and the three subspaces are the first subspace 100b, the second subspace 100c, and the third three Subspace 100 d This includes the following. Each sub-space can accommodate a portion of the 2000 battery.

[0201] In some embodiments, the first subspace 100b may be located between the first side member 21 and the second side member 22, and the second subspace 100c and the third subspace 100d may be symmetrically positioned based on the center of the first subspace 100b.

[0202] In some embodiments, the sizes of the second subspace 100c and the third subspace 100d may be the same or different, and if the sizes of the second subspace 100c and the third subspace 100d are the same, it may be understood that the volume of the battery 2000 portion in the second subspace 100c is equal to the volume of the battery 2000 portion in the third subspace 100d. In some embodiments, the sizes of the first subspace 100b, the second subspace 100c and the third subspace 100d may be the same or different.

[0203] In the above plan, the vehicle frame 20 may include a first side member 21 and a second side member 22 in the girder. For example, the vehicle frame 20 may include a first side member 21 and a second side member 22 in the girder of a large vehicle 10000 (e.g., a heavy truck). By dividing the storage space 100a into a first sub-space 100b, a second sub-space 100c, and a third sub-space 100d based on the first side member 21 and the second side member 22, and distributing the weight of the battery 2000 uniformly based on the positions of the first side member 21 and the second side member 22, the influence of the battery 2000's mounting on the vehicle body 1000's center of gravity is reduced, and the vehicle body 1000 can be given relatively high driving reliability.

[0204] According to some embodiments of this application, referring to Figure 2, at least one first mounting portion 300 is installed in the first sub-space 100b, at least one first mounting portion 300 is installed in the second sub-space 100c, and at least one first mounting portion 300 is installed in the third sub-space 100d.

[0205] Each storage space 100a is provided with one set of first mounting parts 300. The statement "at least one first mounting part 300 is provided in the first sub-space 100b, at least one first mounting part 300 is provided in the second sub-space 100c, and at least one first mounting part 300 is provided in the third sub-space 100d" can be understood as meaning that the parts of the battery 2000 located in the first sub-space 100b, the second sub-space 100c, and the third sub-space 100d can each be connected to the corresponding first mounting part 300.

[0206] In some embodiments, one, two, three or more first mounting parts 300 are installed in the first sub-space 100b. One, two, three or more first mounting parts 300 are installed in the second sub-space 100c. One, two, three or more first mounting parts 300 are installed in the third sub-space 100d.

[0207] In the above-described solution, by distributing and installing at least one first mounting portion 300 in the first sub-space 100b, the second sub-space 100c, and the third sub-space 100d, the battery 2000 is effectively connected, thereby stably attaching the battery 2000 to the vehicle body 1000, reducing the risk of the battery 2000 falling off, and enabling the vehicle body 1000 to have relatively high driving reliability.

[0208] According to some embodiments of this application, referring to Figure 3, at least two first mounting portions 300 are installed in the first subspace 100b, at least two first mounting portions 300 are installed in the second subspace 100c, and at least two first mounting portions 300 are installed in the third subspace 100d.

[0209] The statement "at least two first mounting parts 300 are installed in the first sub-space 100b, at least two first mounting parts 300 are installed in the second sub-space 100c, and at least two first mounting parts 300 are installed in the third sub-space 100d" may be understood as meaning that in the accommodation space 100a, at least two first mounting parts 300 are installed in each sub-space, that is, one set of first mounting parts 300 includes at least six first mounting parts 300.

[0210] In some embodiments, referring to Figure 3, four first mounting parts 300 are installed in the first sub-space 100b, and these four first mounting parts 300 are installed corresponding to both sides in the width direction of the battery 2000, so that the parts of the battery 2000 in the first sub-space 100b can be connected together. Four first mounting parts 300 are installed in the second sub-space 100c, and these four first mounting parts 300 are installed corresponding to both sides in the width direction of the battery 2000, so that the parts of the battery 2000 in the second sub-space 100c can be connected together. Four first mounting parts 300 are installed in the third sub-space 100d, and these four first mounting parts 300 are installed corresponding to both sides in the width direction of the battery 2000, so that the parts of the battery 2000 in the third sub-space 100d can be connected together.

[0211] In the above-described solution, at least two first mounting parts 300 are distributed and installed in the first sub-space 100b, the second sub-space 100c, and the third sub-space 100d, that is, at least six first mounting parts 300 are installed within the housing space 100a, and the six first mounting parts 300 are arranged according to the first sub-space 100b, the second sub-space 100c, and the third sub-space 100d.

And / or, at least two first mounting portions 300 in a third sub-space 100d are respectively installed on opposite sides of the third sub-space 100d along the longitudinal direction y of the vehicle frame.

[0213] In some embodiments, along the longitudinal direction y of the vehicle frame (which may also be along the direction of arrangement of the multiple batteries 2000), the multiple first mounting portions 300 in the first subspace 100b are installed on both sides of the first subspace 100b and connected to the portions of the batteries 2000 on both sides of the vehicle frame in the longitudinal direction y.

The multiple first mounting portions 300 in the third sub-space 100d are installed on both sides of the third sub-space 100d and connected to the portions of the batteries 2000 on both sides of the vehicle frame in the longitudinal direction y.

[0216] In the above-described solution, by installing at least two first mounting portions 300 within the first sub-space 100b on opposing sides along the longitudinal direction of the vehicle frame 20 in the first sub-space 100b, the portions of the battery 2000 on both sides of the vehicle frame 20 in the longitudinal direction are connected and restrained, the force applied to the battery 2000 is made uniform, and the risk of the battery 2000 falling out is reduced. Similarly, by installing at least two first mounting parts 300 in the second sub-space 100c on opposing sides along the longitudinal direction of the vehicle frame 20 in the second sub-space 100c, the longitudinal sides of the vehicle frame 20 of the battery 2000 are connected and restrained, the force acting on the battery 2000 is made uniform, and the risk of the battery 2000 falling out is reduced. Likewise, by installing at least two first mounting parts 300 in the third sub-space 100d on opposing sides along the longitudinal direction of the vehicle frame 20 in the third sub-space 100d, the longitudinal sides of the vehicle frame 20 of the battery 2000 are connected and restrained, the force acting on the battery 2000 is made uniform, the risk of the battery 2000 falling out is reduced, and the vehicle body 1000 can be given relatively high running reliability.

By aligning the first direction parallel to the lateral direction x of the vehicle frame, that is, by arranging multiple batteries 2000 along the lateral direction x of the vehicle frame, power exchange can be performed along the width direction of the vehicle body 1000, effectively reducing the movement path of the batteries 2000 and improving power exchange efficiency compared to power exchange in the longitudinal direction of the vehicle body 1000.

[0222] According to some other embodiments of this application, the vehicle frame 20 includes a first side member 21 and a second side member 22, and the number of accommodation spaces 100a is at least two, with at least one accommodation space 100a located on the side of the first side member 21 away from the second side member 22, and at least one accommodation space 100a located on the side of the second side member 22 away from the first side member 21.

The first side member 21 and the second side member 22 may be installed opposite each other with a gap between them, and the direction of the gap between the first side member 21 and the second side member 22 may be the width direction of the vehicle body 1000 or the lateral direction x of the vehicle frame, and the direction in which the first side member 21 and the second side member 22 extend may be the longitudinal direction of the vehicle body 1000.

[0224] In some embodiments, the number of accommodation spaces 100a may be two or more. Some of the accommodation spaces 100a may be located on the side of the first side member 21 away from the second side member 22, and other accommodation spaces 100a may be located on the side of the second side member 22 away from the first side member 21.

[0225] In the above plan, the vehicle frame 20 may include a first side member 21 and a second side member 22 in the girder. For example, the vehicle frame 20 may include a first side member 21 and a second side member 22 in the girder of a large vehicle 10000 (e.g., a heavy truck). By providing a storage space 100a on the side of the first side member 21 away from the second side member 22, and providing a storage space 100a on the side of the second side member 22 away from the first side member 21, that is, by arranging the batteries 2000 on both sides of the vehicle frame 20, the influence of the battery 2000 mounting on the center of gravity of the vehicle body 1000 can be reduced, and the vehicle body 1000 can be given relatively high driving reliability.

[0226] According to some embodiments of this application, referring to Figure 6, there are at least three accommodation spaces 100a, and at least one accommodation space 100a is located between the first side member 21 and the second side member 22.

[0227] There are at least three storage spaces 100a, meaning that the bracket 10 can mount at least three batteries 2000. At least one storage space 100a is located between the first side member 21 and the second side member 22, meaning that at least one battery 2000 may be located between the first side member 21 and the second side member 22.

[0228] In the above-described solution, by placing the battery 2000 between the first side member 21 and the second side member 22, the influence of the battery 2000's mounting on the center of gravity of the vehicle body 1000 is reduced, and the vehicle body 1000 can be given relatively high driving reliability.

[0229] According to some embodiments of this application, referring to Figures 2 and 6, the first mounting portion 300 is installed at least at one end along the first direction of the housing space 100a.

[0230] The statement "the first mounting portion 300 is installed at at least one end of the accommodation space 100a along the first direction" may be understood to mean that, in the first direction, the first mounting portion 300 is installed at one end of the accommodation space 100a, or that the first mounting portions 300 are installed at both opposing ends of the accommodation space 100a.

[0231] In the above-described solution, by installing the first mounting portion 300 at at least one end of the housing space 100a in the first direction, the connection of the battery 2000 in the first direction can be effectively restrained, reducing the risk of the battery 2000 falling out and improving the driving reliability of the vehicle body 1000.

[0232] According to some embodiments of this application, referring to Figure 2, the first mounting portion 300 is installed at opposing ends along the first direction of the housing space 100a.

[0233] In the first direction, first mounting portions 300 are installed at both opposing ends of the accommodation space 100a. In some embodiments, the number of first mounting portions 300 installed at both opposing ends of the accommodation space 100a may be the same or different.

[0234] In the above-described solution, by installing the first mounting portion 300 at opposing ends in the first direction of the housing space 100a, the connection of the battery 2000 can be effectively restrained in the first direction, the force applied to the battery 2000 can be made uniform, the risk of the battery 2000 falling out can be reduced, and the driving reliability of the vehicle body 1000 can be improved.

[0235] According to some embodiments of this application, referring to Figure 2, the accommodation space 100a has a first end and a second end facing each other along a first direction, and the first mounting portion 300 installed at the first end and the first mounting portion 300 installed at the second end are offset from each other.

[0236] The first and second ends are two opposing parts of the housing space 100a in the first direction. In some embodiments, the first and second ends correspond to two opposing edges of the battery in the first direction.

[0237] The statement that "the first mounting portion 300 installed at the first end and the first mounting portion 300 installed at the second end are offset from each other" can be understood as meaning that, along the first direction, the projection of the first mounting portion 300 installed at the first end does not overlap with the projection of the first mounting portion 300 installed at the second end. In other words, it can be understood as meaning that the first mounting portion 300 installed at the first end is translated to the second end along the first direction without interfering with the first mounting portion 300 installed at the second end.

[0238] In the above plan, by offsetting the first mounting parts 300 located at opposite ends in the storage space 100a, a visual deterrent effect is achieved when mounting the battery 2000, reducing the risk of incorrect mounting of the battery 2000, while a visual deterrent effect is achieved when mounting the bracket 10, reducing the risk of incorrect mounting of the bracket 10.

[0239] According to some embodiments of this application, the first mounting portions 300 at the adjacent ends of two adjacent storage spaces 100a are offset from each other.

[0240] The statement that "the first mounting portions 300 at the adjacent ends of two adjacent storage spaces 100a are offset from each other" can also be understood as the corresponding first mounting portions 300 at the adjacent parts of the two batteries 2000 in the two adjacent storage spaces 100a being offset from each other. Referring to Figure 2, by translating the first mounting portion 300 installed at the end of one of the storage spaces 100a that is closer to the other storage space 100a along the first direction, it does not interfere with the first mounting portion 300 originally installed at the end of the other storage space 100a that is closer to the other storage space 100a. In other words, the first mounting portions 300 at the adjacent ends of two adjacent storage spaces 100a are offset from each other, thereby creating distance not only from each other in the first direction but also in a direction perpendicular to the first direction.

[0241] In the above solution, during power exchange, multiple power exchange execution ends (e.g., power exchange batch heads) can simultaneously act on multiple first mounting units 300 and the battery 2000 at the points where they are connected to each other. As two adjacent housing spaces 100a move closer to each other in the first direction, by offsetting the first mounting units 300 at the adjacent ends of the two adjacent housing spaces 100a, the risk of interference between the two adjacent power exchange execution ends is reduced, allowing multiple power exchange execution ends to operate simultaneously and improving power exchange efficiency.

[0242] According to some embodiments of this application, as can be seen from Figures 2 and 3, the size of the accommodation space 100a along the first direction is smaller than the size along the second direction, and the first direction, the second direction and the gravity direction z are perpendicular to each other.

[0243] The first direction may be the direction of arrangement of the multiple accommodation spaces 100a, and the second direction may be perpendicular to the first direction and perpendicular to the direction of gravity z. In some embodiments, if the first direction is the longitudinal direction y of the vehicle frame, the second direction may be the transverse direction x of the vehicle frame. If the first direction is the transverse direction x of the vehicle frame, the second direction may be the longitudinal direction y of the vehicle frame.

[0244] In some embodiments, the storage space 100a may be a rectangular space, the size of the storage space 100a in a first direction may be smaller than the size in a second direction, and the storage space 100a can accommodate a long or rectangular battery 2000, the size of the battery 2000 in a first direction may be smaller than the size in a second direction.

[0245] In the above solution, the fact that the size of the housing space 100a along the first direction is smaller than the size along the second direction may be understood as the size of the battery cell to be housed in the housing space 100a along the first direction being smaller than the size along the second direction, that is, the size of the battery 2000 in the second direction may be the length of the battery 2000. Therefore, the fact that the first mounting portion 300 is installed at least one end of the housing space 100a along the first direction may be understood as the first mounting portion 300 corresponding to both sides of the relatively shorter size of the battery 2000, which reduces the risk of the central part of the battery 2000 sinking downward due to gravity and improves the connection stability between the battery 2000 and the bracket 10, compared to the first mounting portion 300 corresponding to both sides of the relatively longer size of the battery 2000.

[0246] Referring to some embodiments of this application, specifically Figures 7 and 8, Figure 7 is a schematic diagram of the vehicle frame 20 and bracket 10 in some embodiments of this application, and Figure 8 is an enlarged view of A in Figure 7.

[0247] The vehicle frame 20 includes a pair of side members, and the bracket 10 includes at least one mounting unit 11, each mounting unit 11 including a mounting beam 12 and a connecting portion 13, the mounting beam 12 extending along the lateral x direction of the vehicle frame. Along the lateral x direction of the vehicle frame, the connecting portion 13 is connected to the outer surface of the side member vehicle frame 20. The mounting beam 12 is connected to the connecting portion 13. A first mounting portion 300 is installed on the mounting beam 12.

[0248] In some embodiments, the vehicle body 1000 can be applied to a commercial truck (e.g., a heavy truck) or a passenger car (e.g., a large bus), and the body frame 20 may include a pair of side members (which may be a first side member 21 and a second side member 22) that are positioned opposite each other and spaced apart. The lateral direction x of the body frame may be the direction of arrangement of this pair of side members, and in some embodiments, the lateral direction x of the body frame may be the width direction of the vehicle 10000. The longitudinal direction y of the body frame may be the direction of extension of the side members, and in some embodiments, the lateral direction x of the body frame may be the longitudinal direction or the direction of travel of the vehicle 10000.

[0249] The mounting unit 11 is a unit for mounting the battery 2000 on the bracket 10. The mounting unit 11 includes a mounting beam 12 and a connecting portion 13. The connecting portion 13 is connected to the outer surface of the side member. The side of the side member facing another side member may be an inner surface, and the side of the side member away from another side member may be an outer surface. In some embodiments, the connecting portion 13 can be connected to the outer surface of the side member by welding, screw connection or other connection methods.

[0250] The mounting beam 12 is a beam structure, which may be rod-shaped, and referring to Figure 7, the mounting beam 12 can extend along the lateral direction x of the vehicle frame. In some embodiments, the mounting beam 12 may be located outside the vehicle frame 20. In some embodiments, the mounting beam 12 may be located between a pair of side members of the vehicle frame 20. In some embodiments, a portion of the mounting beam 12 may be located between a pair of side members of the vehicle frame 20, and the portion of the mounting beam 12 may be outside one of the side members. In some embodiments, a portion of the mounting beam 12 may be located between a pair of side members of the vehicle frame 20, and the portion of the mounting beam 12 may be on both sides of the vehicle frame 20 along the lateral direction x of the vehicle frame.

[0251] The mounting beam 12 can be connected to the vehicle body frame 20.

[0252] The mounting beam 12 can be connected directly or indirectly to the connection portion 13, thereby connecting the mounting beam 12 to the vehicle body frame 20. In some embodiments, the mounting beam 12 can be connected to the connection portion 13 by welding, crimping, screw connection, or other connection methods. In some embodiments, the mounting beam 12 can be manufactured by integral molding with the connection portion 13.

[0253] The mounting beam 12 may be configured such that the first mounting portion 300 is mounted on the bracket assembly 100 and then mounted on the mounting beam 12, and the mounting beam 12 may be configured to support the battery 2000 by the first mounting portion 300. In some embodiments, the mounting beam 12 may be connected to the vehicle frame 20, for example, by welding, screw connection or other connection method.

[0254] In some embodiments, the mounting unit 11 may be used to detachably connect to the battery 2000, and the battery 2000 may be located on both sides of the mounting unit 11. stomach In some embodiments, the mounting unit 11 can be fitted onto a first mounting portion 300 on the vehicle frame 20 to mount the battery 2000 together.

[0255] In the above solution, the vehicle frame 20 may include a pair of side members in the girder. For example, the vehicle frame 20 may include a pair of side members in the girder of a large vehicle 10000 (e.g., a heavy truck). By installing the connecting portion 13, the mount beam 12 is effectively connected to the side members, allowing the mount beam 12 to effectively mount the battery 2000 by the first mount portion 300, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle body 1000.

[0256] According to some embodiments of this application, the connecting portion 13 extends along the direction of gravity z.

[0257] In some embodiments, the direction of gravity z is perpendicular to the longitudinal direction y and the transverse direction x of the vehicle frame.

[0258] The statement "the connecting portion 13 extends along the direction of gravity z" may be understood as the connecting portion 13 having a surface parallel to the direction of gravity z, and this surface being able to be attached to the outer surface of the side member.

[0259] In the above-described solution, by installing the connection portion 13 so as to extend along the direction of gravity z, the connection portion 13 has a relatively large area in the direction of gravity z when connected to the side member, thereby improving the connection stability between the mount beam 12 and the side member, reducing the risk of the battery 2000 falling off, and improving the driving reliability of the vehicle body 1000.

[0260] According to some embodiments of this application, referring to Figures 7 and 8, the mounting unit 11 further includes a rib plate 14, which is located on the outside of the vehicle body frame 20 along the lateral x direction of the vehicle body frame, and the rib plate 14 is connected to a connector 13 and a mounting beam 12.

[0261] The rib plate 14 is a member connected to the connection portion 13 and the mount beam 12. In some embodiments, the rib plate 14 may be a member for reinforcing the structural strength of the connection portion 13, the mount beam 12, and the side member. In some embodiments, the rib plate 14 may be a reinforcing bar, reinforcing beam, or reinforcing rib installed between the connection portion 13 and the mount beam 12.

[0262] In some embodiments, the rib plate 14 can be connected to the connection portion 13 by welding, screw connection or other connection method. Alternatively, in some embodiments, the rib plate 14 can be manufactured by integral molding with the connection portion 13. In some embodiments, the rib plate 14 can be connected to the mount beam 12 by welding, screw connection or other connection method. In some embodiments, referring to Figure 9, Figure 9 is a schematic diagram of the local structure of the connection portion 13, mount beam 12, rib plate 14 and side member in some embodiments of the present application. The rib plate 14 may be plate-shaped, and may be formed by bonding two plate-shaped structural members together, with burrings 140 formed at the ends of the two plate-shaped structural members facing the mount beam 12, and the burrings 140 of the two plate-shaped structural members are folded back toward opposite sides and welded together or connected to the mount beam 12 by screw connection.

[0263] In the above-described method, by installing the rib plate 14 on the outside of the vehicle frame 20, the space between the connection part 13 and the mount beam 12 can be used rationally, while the structural strength between the connection part 13 and the mount beam 12 can be improved, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle body 1000.

[0264] In some embodiments, a notch is formed on the end face of the rib plate 14 facing the mount beam 12, and the notch is positioned to correspond to the first mount portion 300 on the mount beam 12, and the notch is used to avoid the first mount portion 300 and reduce interference with the portion of the rib plate 14 where the battery 2000 and the first mount portion 300 are connected to each other.

[0265] Referring to Figure 10, which is a schematic diagram of a mount unit 11 in some embodiments of the present application, the connection portion 13 includes a first subconnection portion 130 and a second subconnection portion 131, the first subconnection portion 130 and the second subconnection portion 131 each extending in opposite directions from the edge of the rib plate 14, and both the first subconnection portion 130 and the second subconnection portion 131 are connected to the outer surface of the side member.

[0266] The first sub-connecting portion 130 is a member that connects the rib plate 14 to the outer surface of the side member. In some embodiments, the first sub-connecting portion 130 is plate-shaped, and the surface that is separated from the rib plate 14 can be connected to the outer surface of the side member by welding, screw connection or other connection method. The second sub-connecting portion 131 is a member that connects the rib plate 14 to the outer surface of the side member. In some embodiments, the second sub-connecting portion 131 is plate-shaped, and the surface that is separated from the rib plate 14 can be connected to the outer surface of the side member by welding, screw connection or other connection method.

[0267] The statement that "the first sub-connecting portion 130 and the second sub-connecting portion 131 each extend in opposite directions from the edge of the rib plate 14" may be understood as the first sub-connecting portion 130 and the second sub-connecting portion 131 being located on opposing sides of the rib plate 14, either along the thickness direction of the rib plate 14 or along the longitudinal direction y of the vehicle frame.

[0268] In some embodiments, the number of first subconnectors 130 may be one, and in some other embodiments, the number of first subconnectors 130 may be multiple, and the multiple first subconnectors 130 are spaced apart along the direction of gravity z.

[0269] In some embodiments, referring to Figure 9, the mounting unit 11 may further include a reinforcing piece 17, the reinforcing piece 17 comprising a first portion 170, a second portion 171, and a third portion 172, wherein the first portion 170 is connected to the top surface of the side member, the ends of the second portion 171 and the third portion 172 are connected to the first portion 170, the second portion 171 and the third portion 172 are installed opposite each other along the longitudinal direction y of the vehicle frame, a relief slit is formed between the second portion 171 and the third portion 172, the relief slit allows the second portion 171 and the third portion 172 to be positioned on opposite sides of the rib plate 14 by escaping the rib plate 14. The second portion 171 can contact the first subconnector 130, that is, the first subconnector 130 is located between the second portion 171 and the side member; the third portion 172 can contact the second subconnector 131, that is, the second subconnector 131 is located between the third portion 172 and the side member.

[0270] In the above-described solution, by installing a first sub-connection part 130 and a second sub-connection part 131, and by installing the first sub-connection part 130 and the second sub-connection part 131 on both sides of the rib plate 14, the connection stability between the connection part 13 and the side member is effectively improved, thereby effectively improving the structural stability between the connection part 13, the rib plate 14 and the mount beam 12, effectively reducing the risk of the battery 2000 falling off, and improving the driving reliability of the vehicle body 1000.

[0271] According to some embodiments of this application, referring to Figure 7, the bracket 10 includes a plurality of mounting units 11, which are spaced apart along the longitudinal direction y of the vehicle frame. The bracket 10 further includes a connecting beam 15, which extends along the longitudinal direction y of the vehicle frame and connects to two adjacent mounting units 11.

[0272] Referring to Figure 7, multiple mounting units 11 are installed at intervals along the longitudinal direction y of the vehicle frame. In some embodiments, the battery 2000 may be located between two adjacent mounting units 11. In some embodiments, the number of mounting units 11 may be two, three, or four, etc. Referring to Figure 7, the number of mounting units 11 is four. In some embodiments, the gap between two adjacent mounting units 11 may or may not be equal.

[0273] Referring to Figure 7, the bracket 10 further includes a connecting beam 15, which is a beam structure, and the connecting beam 15 is connected to two adjacent mounting units 11, and its role may include improving the structural stability of the two mounting units 11.

[0274] In some embodiments, the connecting beam 15 may be plate-shaped, pipe-shaped, or rod-shaped. In some embodiments, the connecting beam 15 can be connected to two adjacent mounting units 11 by bonding, welding, crimping, or screwing.

[0275] In some embodiments, the connecting beam 15 can be connected to the ends of two adjacent mounting beams 12. In some embodiments, the connecting beam 15 can be connected to the ends of two adjacent rib plates 14. In some embodiments, the connecting beam 15 can be connected to the ends of two adjacent connection points 13. In some embodiments, there may be multiple connecting beams 15, some of which can be connected to the ends of two adjacent rib plates 14, some of which can be connected to the ends of two adjacent rib plates 14, and some of which can be connected to the ends of two adjacent connection points 13.

[0276] In the above-described solution, by installing multiple mounting units 11, it is possible to mount multiple batteries 2000 and achieve the objective of exchanging power as needed, thereby reducing the cost of power exchange. On the other hand, by installing connecting beams 15 and connecting them to two adjacent mounting units 11, the structural stability between the two adjacent mounting units 11 can be effectively improved, the capacity to mount batteries 2000 can be increased, the risk of batteries 2000 falling off can be reduced, and the driving reliability of the vehicle body 1000 can be improved.

[0277] Some embodiments of this application refer to Figures 10 and 11. Figure 11 is a front view of the mount unit 11 and side member in some embodiments of this application.

[0278] Each mounting unit 11 includes two connection parts 13, which are spaced apart along the lateral x direction of the vehicle frame, and a pair of side members are located between the two connection parts 13, with each connection part 13 connecting to the outer surface of the corresponding side member.

[0279] The lateral direction x of the vehicle body frame may be the arrangement direction of a pair of side members. In some embodiments, the pair of side members includes a first side member 21 and a second side member 22. Each mounting unit 11 includes two connection portions 13, corresponding to the two side members, that is, corresponding to the first side member 21 and the second side member 22. One of the connection portions 13 is connected to the outer surface of the first side member 21, and the other connection portion 13 is connected to the outer surface of the second side member 22.

[0280] Referring to FIG. 11, the portion of the mounting beam 12 may be between a pair of side members, and the remaining portion of the mounting beam 12 may be located on both sides of the pair of side members (for example, a part of the mounting beam 12 extends beyond the first side member 21, and a part of the mounting beam 12 extends beyond the second side member 22). In some embodiments, at least one first mounting portion 300 may be provided in the portion of the mounting beam 12 located between the pair of side members. At least one first mounting portion 300 may be provided in the portion of the mounting beam 12 extending beyond the first side member 21. At least one first mounting portion 300 may be provided in the portion of the mounting beam 12 extending beyond the second side member 22.

[0281] In the above solution, by providing the two connection portions 13, the connection portions 13 are connected to the outer surfaces of the corresponding side members, that is, the two side members of the vehicle body frame 20 are respectively connected by the corresponding connection portions 13, thereby having a stable connection relationship between the mounting unit 11 and the vehicle body frame 20, reducing the risk of the battery 2000 falling off, and improving the running reliability of the vehicle 10000. On the other hand, since the two connection portions 13 are provided and the two connection portions 13 are provided at intervals along the lateral direction x of the vehicle body frame, that is, the mounting beam 12 can install more first mounting portions 300 to mount the battery 2000 with a larger volume, and further effectively improve the endurance of the vehicle 10000.

[0282] According to some embodiments of the present application, referring to FIG. 7, the bracket 10 includes a plurality of mounting units 11. Along the longitudinal direction y of the vehicle body frame, the plurality of mounting units 11 are arranged at intervals, and an accommodation space 100a is formed between two adjacent mounting units 11. Each accommodation space 100a is used to accommodate one battery 2000.

[0283] In some embodiments, the plurality of mounting units 11 can be arranged at intervals along the longitudinal direction y of the vehicle body frame, and an accommodation space 100a can be formed between two adjacent mounting units 11.

[0284] In some embodiments, two mounting units 11 are arranged at intervals along the longitudinal direction y of the vehicle body frame, and an accommodation space 100a for accommodating one battery 2000 can be formed between the two mounting units 11. The remaining batteries 2000 may be installed on the side away from another mounting unit 11 of one of the mounting units 11.

[0285] In some embodiments, the number of mounting units 11 may be at least three, and at least two accommodation spaces 100a arranged along the longitudinal direction y of the vehicle body frame in the longitudinal direction y of the vehicle body frame are formed. Each accommodation space 100a is independent of each other. Each accommodation space 100a may be used to accommodate one battery 2000, and the battery 2000 located in the accommodation space 100a can be connected by a set of first mounting parts 300 in the accommodation space 100a.

[0286] In the above solution, by arranging a plurality of mounting units 11 at intervals in the longitudinal direction y of the vehicle body frame, a plurality of accommodation spaces 100a arranged along the longitudinal direction y of the vehicle body frame are formed, and each battery 2000 is neatly installed in the corresponding accommodation space 100a, without interference between the batteries 2000, and the power exchange efficiency of the vehicle body 1000 can be improved.

[0287] Referring to Figure 12, which is a schematic diagram of the bracket 10 and the vehicle frame 20 in some other embodiments of the present application.

[0288] Each mounting unit 11 includes one connection part 13. There are two brackets 10, and a pair of side members are located between the two brackets 10 along the lateral x direction of the vehicle frame.

[0289] In some embodiments, "each mount unit 11 includes one connector 13" may be understood as a mount unit 11 including one mount beam 12 and one connector 13. The mount beam 12 may be located outside the side member, and the connector 13 may be located outside the side member and connected to the outer surface of the side member. The mount beam 12 is connected to the connector 13. One bracket 10 may be located on one side of the vehicle frame 20; that is, if there is only one bracket 10 in the vehicle body 1000, this one bracket 10 may be installed on one side of the vehicle frame 20.

[0290] The statement "There are two brackets 10, and along the lateral x direction of the vehicle frame, a pair of side members are located between the two brackets 10" may be understood as meaning that there are two brackets 10, and the two brackets 10 are located on each side of the vehicle frame 20, with one bracket 10 connected to one side member of the vehicle frame 20 and the other bracket 10 connected to the other side member of the vehicle frame 20.

[0291] In the above solution, the mounting unit 11 has a simple structure and is easy to manufacture. The mounting unit 11 can stably connect the mounting beam 12 to the outer surface of one of its side members by a single connection part 13, that is, one bracket 10 can be stably mounted on the outside of one of its side members on the vehicle frame 20. On the other hand, by installing brackets 10 on both sides of the vehicle frame 20, more batteries 2000 can be mounted, increasing the upper limit of the number of power exchange batteries 2000, and further improving the driving range of the vehicle 10000.

[0301] In the above solution, by installing the second mounting part 301 on the cross member 23, there is a mounting point between the battery 2000 and the cross member 23, improving the connection stability between the battery 2000 and the vehicle body 1000 and reducing the risk of the battery 2000 falling off. In some embodiments, when the battery 2000 is arranged along the longitudinal direction y of the vehicle body frame, a plurality of batteries 2000 can be arranged side by side along the transverse direction x of the vehicle body frame. By installing the second mounting part 301 on the cross member 23, at least one row of batteries 2000 can be mounted at the corresponding position of the cross member 23. In some embodiments, when the battery 2000 is arranged along the transverse direction x of the vehicle body frame, the battery 2000 can be mounted together by the first mounting part 300 above and the mounting part on the cross member 23.

The reinforcing plate 16 is connected to the cross member 23, and through holes corresponding to the second mounting part 301 are provided in the reinforcing plate 16.

[0303] In some embodiments, the reinforcing plate 16 may be plate-shaped, and the reinforcing plate 16 may be installed on the surface of the cross member 23 facing the ground, that is, the reinforcing plate 16 may be installed on the lower surface of the cross member 23.

[0306] According to some embodiments of this application, referring to Figure 10, the mounting beam 12 is a square pipe.

[0307] In some embodiments, the square pipe may be a tubular structure having a chamber inside. In some embodiments, the square pipe may be made of square steel.

[0308] In the above plan, by installing the mounting beam 12 on a square pipe, material costs are low, the strength of the material structure is high, the battery 2000 can be effectively mounted, and the risk of the battery 2000 falling off can be reduced.

[0309] According to some embodiments of this application, referring to Figure 4, the projection of the bracket 10 and the projection of the vehicle body frame 20 overlap at least partially along the lateral x direction of the vehicle body frame.

[0310] The lateral direction x of the vehicle frame may be the direction of the arrangement of a pair of side members in the vehicle frame 20, or the lateral direction x of the vehicle frame may be the width direction of the vehicle 10000. The statement that "the projection of the bracket 10 and the projection of the vehicle frame 20 overlap at least partially along the lateral direction x of the vehicle frame" may be understood as the bracket 10 utilizing the space in which the vehicle frame 20 is located in the height direction (i.e., the gravity direction z). Alternatively, it may be understood that between brackets 10 of the same standard, raising the bracket 10 will cause the projection of the bracket 10 in the lateral direction x of the vehicle frame to fall onto the vehicle frame 20, thereby increasing the clearance of the bracket 10 from the ground.

[0311] In the direction described above, the lateral direction x of the vehicle frame may be a direction of travel perpendicular to the vehicle body 1000, and by installing the bracket 10 so that its projection at least partially overlaps with the projection of the vehicle frame 20, the gap between the bracket 10 and the ground can be effectively improved, reducing the impact of the bracket 10's installation on the gap between the vehicle body 1000 and the ground, thereby improving the driving reliability of the vehicle body 1000.

[0312] Referring to Figure 14, which is a front view of a bracket 10 and a vehicle frame 20 in some embodiments of the present application, the bracket 10 has an upwardly opening relief groove 10a, and at least a portion of the vehicle frame 20 is housed in the relief groove 10a.

[0313] In some embodiments, "opening upward" may mean that when the vehicle body 1000 is located on the ground, the bracket 10 can be attached from below the vehicle frame 20.

[0314] In some embodiments, the bracket 10 has a relief groove 10a for accommodating at least a portion of the vehicle frame 20, for example, the relief groove 10a is used to accommodate a pair of side members of the vehicle frame 20 (e.g., a first side member 21 and a second side member 22), that is, by providing clearance for the pair of side members, the side members can pass through the bracket 10 in the longitudinal direction y of the vehicle frame.

[0315] In some other embodiments, referring to Figure 15, which is a front view of the bracket 10 and the vehicle frame 20 in some other embodiments of the present application. In Figure 15, the relief groove 10a may be used to accommodate one side member of the vehicle frame 20 (for example, a first side member 21 or a second side member 22), that is, by providing relief for one side member, this side member can penetrate the bracket 10 in the longitudinal direction y of the vehicle frame.

[0316] The statement that "at least a portion of the vehicle frame 20 is housed in the relief groove 10a" may be understood as meaning that, in the height direction, the portion of the bracket 10 can utilize the space in which the vehicle frame 20 is located.

In some embodiments, the body frame 20 may be connected to the side wall of the relief groove 10a, and the body frame 20 may be connected to the side wall of the relief groove 10a by welding, riveting, screw connection or other connection method. In some embodiments, the body frame 20 may be connected to both the side wall and the bottom wall of the relief groove 10a.

[0320] In the above solution, since at least a portion of the vehicle frame 20 is housed in the relief groove 10a, the vehicle frame 20 can be connected to the bottom wall and / or side wall of the relief groove 10a, allowing for rational use of the relief groove 10a. This not only allows the relief groove 10a to clear the bracket 10, but also enables the connection between the bracket 10 and the vehicle frame 20, simplifying the connection structure between the bracket 10 and the vehicle frame 20, reducing the difficulty of installation, and lowering installation costs.

[0332] The clearance space 2001 may be a recess in the battery 2000 to accommodate the bracket assembly 100. Referring to Figures 3 and 17, in the height direction, the upper surface of the battery 2000 may be an uneven surface, and the recessed portion forms the clearance space 2001.

[0333] In some embodiments, the bracket assembly 100 includes the vehicle frame 20, and the clearance space 2001 can accommodate a pair of side members of the vehicle frame 20, meaning that the portion of the upper surface of the battery 2000 that protrudes can utilize the space in which the vehicle frame 20 is located.

[0334] In the above solution, by installing a clearance space 2001 above the battery 2000, the space where the bracket assembly 100 is located can be rationally utilized, improving the electrical capacity of the battery 2000 and providing the vehicle 10000 with a longer range.

[0336] The lateral direction x of the vehicle frame may be the direction of arrangement of a pair of side members in the vehicle frame 20, or it may be the width direction of the vehicle 10000. The statement "along the lateral direction x of the vehicle frame, the projection of the battery 2000 and the projection of the vehicle frame 20 overlap at least partially" may be understood as meaning that in the height direction, the battery 2000 has a portion that protrudes upward, and the projection of this protruding portion on the vehicle frame in the lateral direction x can fall onto the vehicle frame 20. The statement "along the lateral direction x of the vehicle frame, the projection of the battery 2000 and the projection of the vehicle frame 20 overlap at least partially" may be understood as meaning that in the height direction, the battery 2000 can utilize the space in which the vehicle frame 20 is located.

[0337] In the above solution, the lateral direction x of the vehicle frame may be perpendicular to the direction of travel of the vehicle 10000, or it may be understood as the width direction of the vehicle 10000. By installing the battery 2000 along the lateral direction x of the vehicle frame such that the projection of the battery 2000 and the projection of the vehicle frame 20 overlap at least partially, the battery 2000 can rationally utilize the height space of the vehicle body 1000, improve the electrical capacity of the battery 2000, and provide a longer range than the vehicle 10000.
