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

[0004] New energy vehicles have become an important part of the sustainable development of the vehicle industry due to their energy-saving and environmentally friendly advantages. With the development of new energy vehicles, people's requirements for the cruising range of new energy vehicles are also increasing. In order to meet the needs of new energy vehicles to replenish power loss in time during driving, solutions such as battery replacement and timely replenishment of power loss have emerged.

[0005] For new energy vehicles, how to reduce the cost of battery replacement is a technical problem that needs to be solved urgently.

[0006] Summary of the Invention

[0007] The present application provides a vehicle body and a vehicle, which can effectively reduce the cost of battery replacement.

[0008] This application is achieved through the following technical solutions:

[0009] In a first aspect, the present application provides a vehicle body, which includes a bracket assembly and multiple first connectors. The bracket assembly is provided with multiple groups of first mounting parts, each group of first mounting parts is used to detachably connect a battery, the number of first connectors is equal to the number of groups of first mounting parts, and each first connector is used to connect to the second connector of a battery.

[0010] In the above scheme, the vehicle body includes a bracket assembly and a plurality of first connectors. By providing a plurality of first connectors and providing a plurality of groups of first mounting parts on the bracket assembly, the number of batteries that need to be replaced can be adjusted based on the endurance requirement (that is, battery replacement on demand, for example, when the endurance is required to be shorter, a smaller number of batteries can be installed on a corresponding number of first mounting parts in the plurality of groups of first mounting parts, and the second connector of each battery is connected to the corresponding first connector; when the endurance is required to be longer, a larger number of batteries can be installed on a corresponding number of first mounting parts in the plurality of groups of first mounting parts, and the second connector of each battery is connected to the corresponding first connector), thereby saving the cost of additional batteries and effectively reducing the cost of battery replacement.

[0011] According to some embodiments of the present application, the bracket assembly includes a vehicle frame.

[0012] In the above solution, the frame can serve as the primary support for the vehicle body, capable of withstanding various loads both inside and outside the vehicle body. The frame can be provided with a first mounting portion, which, on the one hand, can stably support the battery, improving the stability of the connection between the battery and the vehicle body and reducing the risk of battery detachment. On the other hand, the frame is located at the bottom of the vehicle body, allowing the battery to be replaced from below the vehicle body. Compared to the current backpack-style battery replacement method for heavy trucks (where the battery is installed on the back of the heavy truck cab), this changes the battery layout within the vehicle body, effectively saving space along the length of the vehicle and increasing the vehicle's cargo capacity.

[0013] According to some embodiments of the present application, the bracket assembly further includes a bracket, the bracket is fixedly connected to the vehicle frame, and the bracket is provided with a first mounting portion.

[0014] In the above scheme, by fixedly connecting the bracket to the frame, on the one hand, the impact of the bracket on the structural reliability of the vehicle body can be reduced; on the other hand, the bracket can be stably set on the vehicle body to effectively carry the battery; on the other hand, the bracket can be installed in the frame of the current vehicle body, and its installation difficulty is small and the installation efficiency is fast, which can quickly enable the current vehicle to have the function of on-demand battery replacement.

[0015] According to some embodiments of the present application, the frame includes a first longitudinal beam and a second longitudinal beam, the highest point of the bracket is not higher than the upper end surface of the first longitudinal beam, and the highest point of the bracket is not higher than the upper end surface of the second longitudinal beam.

[0016] In the above solution, the vehicle frame may include the first longitudinal beam and the second longitudinal beam in the beam. For example, the vehicle frame may include the first longitudinal beam and the second longitudinal beam in the beam of a large vehicle (such as a heavy truck). By arranging the bracket on the vehicle frame and not exceeding the upper end surfaces of the first longitudinal beam and the second longitudinal beam, the space above the first longitudinal beam and the second longitudinal beam can be avoided. On the one hand, the interference with the interior of the vehicle body caused by the installation of the bracket can be reduced; on the other hand, compared with the current vehicle body installation bracket, the bracket reinforcement is easy and feasible; on the other hand, when the battery is installed on the bracket, or the first longitudinal beam and the second longitudinal beam, the battery can be replaced from the bottom of the vehicle body. Compared with the current backpack-style battery replacement of heavy trucks (the battery is installed on the back of the heavy truck's cab), the position layout of the battery in the vehicle body is changed, which can effectively save space in the longitudinal direction of the vehicle and increase the vehicle's cargo capacity.

[0017] According to some embodiments of the present application, along the direction from the first longitudinal beam to the second longitudinal beam, the bracket extends beyond the second longitudinal beam.

[0018] In the above solution, by setting the bracket to extend beyond the second longitudinal beam, a larger installation location can be provided for the battery, so that more batteries or larger batteries can be installed to adapt to the different endurance requirements of different vehicles or different endurance requirements of vehicles.

[0019] According to some embodiments of the present application, at least one first mounting portion is provided on a portion of the bracket extending beyond the second longitudinal beam.

[0020] In the above solution, by providing at least one first mounting portion on the portion of the bracket extending beyond the second longitudinal beam, the portion of the battery extending beyond the second longitudinal beam can be connected, so that the battery is stably connected to the bracket, thereby improving the structural stability of the battery and the bracket.

[0021] According to some embodiments of the present application, along the direction from the second longitudinal beam to the first longitudinal beam, the bracket extends beyond the first longitudinal beam.

[0022] In the above solution, by setting the bracket to extend beyond the first longitudinal beam, a larger installation location can be provided for the battery, so that more batteries or larger batteries can be installed to adapt to the different vehicle endurance requirements or different vehicle endurance requirements.

[0023] According to some embodiments of the present application, at least one first mounting portion is provided on a portion of the bracket extending beyond the first longitudinal beam.

[0024] In the above solution, by providing at least one first mounting portion on the portion of the bracket extending beyond the first longitudinal beam, the portion of the battery extending beyond the first longitudinal beam can be connected, so that the battery is stably connected to the bracket, thereby improving the structural stability of the battery and the bracket.

[0025] According to some embodiments of the present application, at least a portion of the bracket is located between the first longitudinal beam and the second longitudinal beam.

[0026] In the above solution, the center of gravity of the vehicle body can be located between the first and second longitudinal beams. Therefore, by positioning at least a portion of the bracket between the first and second longitudinal beams, the effect of the bracket on the center of gravity of the vehicle body can be reduced, thereby improving the vehicle's driving stability. Furthermore, when the battery is mounted on the bracket, a portion of the battery or a portion of the battery can be positioned between the first and second longitudinal beams, thereby reducing the effect of the battery's installation on the center of gravity of the vehicle body and improving the vehicle's driving stability.

[0027] According to some embodiments of the present application, a portion of the bracket located between the first longitudinal beam and the second longitudinal beam is provided with at least one first mounting portion.

[0028] In the above solution, by providing at least one first mounting portion on the portion of the bracket located between the first longitudinal beam and the second longitudinal beam, the portion of the battery located between the first longitudinal beam and the second longitudinal beam can be connected, so that the battery is stably connected to the bracket, thereby improving the structural stability of the battery and the bracket.

[0029] According to some embodiments of the present application, a second mounting portion is provided on the vehicle frame, and the second mounting portion is used to detachably connect the battery.

[0030] In the above solution, by providing the second mounting portion on the vehicle frame and cooperating with the first mounting portion to detachably connect with the battery, the connection stability between the battery and the vehicle body can be improved, thereby improving the driving reliability of the vehicle body.

[0031] According to some embodiments of the present application, the vehicle frame includes a first longitudinal beam and a second longitudinal beam, and the second mounting portion is provided on the first longitudinal beam and / or the second longitudinal beam.

[0032] In the above solution, the vehicle frame may include a first longitudinal beam and a second longitudinal beam of a beam. For example, the vehicle frame may include the first longitudinal beam and the second longitudinal beam of a beam of a large vehicle (such as a heavy truck). By providing the second mounting portion on the first longitudinal beam and / or the second longitudinal beam, the second mounting portion can effectively cooperate with the first mounting portion to effectively connect the battery to the vehicle body, reduce the risk of battery detachment, and improve the driving reliability of the vehicle body.

[0033] According to some embodiments of the present application, the vehicle frame includes a first longitudinal beam, a second longitudinal beam and a cross beam, the cross beam is connected between the first longitudinal beam and the second longitudinal beam, and the second mounting portion is arranged on the cross beam.

[0034] In the above solution, the vehicle frame may include a first longitudinal beam, a second longitudinal beam, and a cross beam in the beam. For example, the vehicle frame may include the first longitudinal beam, a second longitudinal beam, and a cross beam in the beam of a large vehicle (such as a heavy truck). By arranging the second mounting portion on the cross beam, on the one hand, it can effectively cooperate with the first mounting portion to effectively connect the battery to the vehicle body, reduce the risk of battery detachment, and improve the driving reliability of the vehicle body; on the other hand, because the cross beam is located between the first and second longitudinal beams, arranging the second mounting portion on the cross beam can reasonably utilize the space between the first and second longitudinal beams, reduce the interference of the second mounting portion with the bracket, and improve the battery replacement efficiency of the vehicle body.

[0035] According to some embodiments of the present application, the bracket assembly has a plurality of accommodating spaces, the plurality of accommodating spaces are arranged along a first direction, each accommodating space is used to accommodate a battery, and each accommodating space is correspondingly provided with a group of first mounting parts.

[0036] In the above solution, by setting multiple accommodating spaces in the first direction, and each accommodating space is correspondingly provided with a group of first mounting parts, each battery can be installed in the corresponding accommodating space in an orderly manner, and the batteries do not interfere with each other, thereby improving the battery replacement efficiency of the vehicle body.

[0037] According to some embodiments of the present application, the accommodation space has an opening that opens downward, and the opening is used for allowing the battery to enter or leave the accommodation space.

[0038] In the above scheme, by setting a downwardly open opening, the battery can be easily entered or left the storage space from the bottom of the vehicle body. Compared with the current backpack-type battery replacement scheme of heavy trucks, on the one hand, it can save space above the frame and reduce the risk of interference with the vehicle body and damage to the vehicle body caused by the battery replacement mechanism occupying the space above the frame during battery replacement; on the other hand, it changes the position layout of the battery of the vehicle body so that the battery is located at the bottom of the vehicle body, which can effectively save space in the length direction of the vehicle and increase the cargo capacity of the vehicle.

[0039] According to some embodiments of the present application, the first direction is parallel to the longitudinal direction of the frame.

[0040] In the above embodiment, the longitudinal direction of the frame can be parallel to the direction of travel of the vehicle body. The longitudinal direction of the frame can be the direction in which the longitudinal beams in the frame extend. By arranging the first direction parallel to the longitudinal direction of the frame, that is, arranging the multiple batteries along the longitudinal direction of the frame, the center of gravity of the batteries can be aligned closer to the center of the frame in the transverse direction. This reduces the impact of the battery installation on the center of gravity of the vehicle body, thereby improving the driving reliability of the vehicle body.

[0041] According to some embodiments of the present application, the frame includes a first longitudinal beam and a second longitudinal beam, and each accommodating space is divided into a first subspace, a second subspace, and a third subspace by the first longitudinal beam and the second longitudinal beam. The first subspace is located between the first longitudinal beam and the second longitudinal beam, the second subspace is located on the side of the first longitudinal beam away from the second longitudinal beam, and the third subspace is located on the side of the second longitudinal beam away from the first longitudinal beam.

[0042] In the above solution, the vehicle frame can include the first and second longitudinal beams of the main frame. For example, the vehicle frame can include the first and second longitudinal beams of the main frame of a large vehicle (such as a heavy truck). The accommodation space is divided into a first subspace, a second subspace, and a third subspace based on the first and second longitudinal beams. The weight of the battery is distributed based on the position of the first and second longitudinal beams. This can reduce the impact of battery installation on the center of gravity of the vehicle body, thereby improving the driving reliability of the vehicle body.

[0043] According to some embodiments of the present application, the first subspace is correspondingly provided with at least one first mounting portion, the second subspace is correspondingly provided with at least one first mounting portion, and the third subspace is correspondingly provided with at least one first mounting portion.

[0044] In the above scheme, by distributing at least one first mounting portion in the first subspace, the second subspace and the third subspace, the battery can be effectively connected so that the battery can be stably installed on the vehicle body, reducing the risk of the battery falling off and making the vehicle body have higher driving reliability.

[0045] According to some embodiments of the present application, at least two first mounting parts are provided in the first subspace, at least two first mounting parts are provided in the second subspace, and at least two first mounting parts are provided in the third subspace.

[0046] In the above scheme, at least two first mounting parts are distributed in the first subspace, the second subspace and the third subspace, that is, at least six first mounting parts are arranged in the accommodating space, and the six first mounting parts are arranged according to the first subspace, the second subspace and the third subspace, which can connect the battery evenly with force, so that the battery is stably in the accommodating space, reducing the risk of the battery falling off, and making the vehicle body have higher driving reliability.

[0047] According to some embodiments of the present application, at least two first mounting portions within the first subspace are disposed on opposite sides of the first subspace along the longitudinal direction of the vehicle frame. Furthermore, / or, at least two first mounting portions within the second subspace are disposed on opposite sides of the second subspace along the longitudinal direction of the vehicle frame. Furthermore, / or, at least two first mounting portions within the third subspace are disposed on opposite sides of the third subspace along the longitudinal direction of the vehicle frame.

[0048] In the above scheme, by arranging at least two first mounting parts in the first subspace at opposite sides of the first subspace along the longitudinal direction of the frame, the battery can be partially constrained by connection on both sides of the longitudinal direction of the frame, so that the battery is evenly stressed and the risk of battery falling off is reduced; similarly, by arranging at least two first mounting parts in the second subspace at opposite sides of the second subspace along the longitudinal direction of the frame, the battery can be partially constrained by connection on both sides of the longitudinal direction of the frame, so that the battery is evenly stressed and the risk of battery falling off is reduced; similarly, by arranging at least two first mounting parts in the third subspace at opposite sides of the third subspace along the longitudinal direction of the frame, the battery can be partially constrained by connection on both sides of the longitudinal direction of the frame, so that the battery is evenly stressed and the risk of battery falling off is reduced, so that the vehicle body has higher driving reliability.

[0049] According to some embodiments of the present application, the first direction is parallel to the transverse direction of the frame.

[0050] In the above solution, the transverse direction of the frame can be perpendicular to the direction of travel of the vehicle body. The transverse direction of the frame can be the arrangement direction of the pair of longitudinal beams of the frame, and the transverse direction of the frame can also be understood as the width direction of the vehicle body. By setting the first direction parallel to the transverse direction of the frame, that is, arranging multiple batteries along the transverse direction of the frame, battery replacement can be performed along the width direction of the vehicle body. Compared with battery replacement along the length of the vehicle body, the battery travel path can be effectively shortened, thereby improving battery replacement efficiency.

[0051] According to some embodiments of the present application, the frame includes a first longitudinal beam and a second longitudinal beam, the number of accommodating spaces is at least two, at least one accommodating space is located on the side of the first longitudinal beam away from the second longitudinal beam, and at least one accommodating space is located on the side of the second longitudinal beam away from the first longitudinal beam.

[0052] In the above solution, the vehicle frame may include the first and second longitudinal beams of the beam. For example, the frame may include the first and second longitudinal beams of the beam of a large vehicle (such as a heavy truck). By providing a storage space on the side of the first longitudinal beam facing away from the second longitudinal beam, and providing a storage space on the side of the second longitudinal beam facing away from the first longitudinal beam, that is, arranging the batteries on both sides of the frame, the impact of battery installation on the center of gravity of the vehicle body can be reduced, thereby improving the driving reliability of the vehicle body.

[0053] According to some embodiments of the present application, the number of the accommodating spaces is at least three, and at least one accommodating space is located between the first longitudinal beam and the second longitudinal beam.

[0054] In the above solution, by arranging the battery between the first longitudinal beam and the second longitudinal beam, the influence of the installation of the battery on the center of gravity of the vehicle body can be reduced, so that the vehicle body has higher driving reliability.

[0055] According to some embodiments of the present application, the first mounting portion is disposed at at least one end of the accommodating space along the first direction.

[0056] In the above solution, by arranging the first mounting portion at at least one end of the accommodating space in the first direction, the connected battery can be effectively constrained in the first direction, thereby reducing the risk of the battery falling off and improving the driving reliability of the vehicle body.

[0057] According to some embodiments of the present application, the first mounting portions are disposed at opposite ends of the accommodating space along the first direction.

[0058] In the above solution, by arranging the first mounting portion at the opposite end of the accommodating space in the first direction, the connected battery can be effectively constrained in the first direction, so that the battery is evenly stressed, the risk of battery falling off is reduced, and the driving reliability of the vehicle body is improved.

[0059] According to some embodiments of the present application, the accommodating space has a first end and a second end opposite to each other along the first direction, and the first mounting portion arranged at the first end is staggered with the first mounting portion arranged at the second end.

[0060] In the above solution, by staggering the first mounting parts at opposite ends of the accommodating space, on the one hand, it has a fool-proof effect on the installation of the battery and reduces the risk of incorrect installation of the battery; on the other hand, it has a fool-proof effect on the installation of the bracket and reduces the risk of incorrect installation of the bracket.

[0061] According to some embodiments of the present application, the first mounting portions at one end of two adjacent accommodating spaces close to each other are staggered.

[0062] In the above scheme, when swapping batteries, multiple battery swapping execution terminals (such as battery swapping heads) can simultaneously act on the locations where multiple first mounting parts are connected to the batteries. Two adjacent accommodating spaces are close to each other in the first direction. To this end, by staggering the first mounting parts of the adjacent ends of the two adjacent accommodating spaces, the risk of interference between the two adjacent battery swapping execution terminals can be reduced, allowing multiple battery swapping execution terminals to work simultaneously and improve battery swapping efficiency.

[0063] According to some embodiments of the present application, a size of the accommodating space along the first direction is smaller than a size along the second direction, and the first direction, the second direction, and the direction of gravity are perpendicular to each other.

[0064] In the above solution, the size of the storage space along the first direction is smaller than its size along the second direction. This can be understood as the size of the battery cell in the storage space along the first direction being smaller than its size along the second direction. In other words, the size of the battery in the second direction can be the length of the battery. Therefore, when the first mounting portion is disposed at at least one end of the storage space along the first direction, it can be understood that the first mounting portion corresponds to the shorter side of the battery, rather than the longer side of the battery. This can reduce the risk of the middle of the battery collapsing due to gravity, thereby improving the stability of the connection between the battery and the bracket.

[0065] According to some embodiments of the present application, the frame includes a pair of longitudinal beams, the bracket includes at least one mounting unit, each mounting unit includes a mounting beam and a connecting portion, the mounting beam extends along the transverse direction of the frame; along the transverse direction of the frame, the connecting portion is connected to the outer side surface of the longitudinal beam; the mounting beam is connected to the connecting portion; and the mounting beam is provided with a first mounting portion.

[0066] In the above solution, the vehicle frame may include a pair of longitudinal beams in the main beam, for example, the vehicle frame may include a pair of longitudinal beams in the main beam of a large vehicle (such as a heavy truck). By providing the connecting portion, the mounting beam can be effectively connected to the longitudinal beam, so that the mounting beam can effectively support the battery through the first mounting portion, reducing the risk of battery detachment and improving the driving reliability of the vehicle body.

[0067] According to some embodiments of the present application, the connecting portion extends along the direction of gravity.

[0068] In the above solution, by setting the connecting part to extend along the direction of gravity, the connecting part has a larger area in the direction of gravity to be connected to the longitudinal beam, thereby improving the connection stability between the mounting beam and the longitudinal beam, reducing the risk of battery falling off, and improving the driving reliability of the vehicle body.

[0069] According to some embodiments of the present application, the mounting unit further includes a rib plate, which is located on the outer side of the frame along the transverse direction of the frame, and the rib plate connects the connecting portion and the mounting beam.

[0070] In the above scheme, by providing ribs on the outside of the frame, on the one hand, the space between the connecting part and the mounting beam can be reasonably utilized, and on the other hand, the structural strength of the connecting part and the mounting beam can be improved, thereby reducing the risk of battery detachment and improving the driving reliability of the vehicle body.

[0071] According to some embodiments of the present application, the connecting portion includes a first sub-connecting portion and a second sub-connecting portion, and the first sub-connecting portion and the second sub-connecting portion extend in opposite directions from the edge of the rib plate, respectively, and the first sub-connecting portion and the second sub-connecting portion are both connected to the outer side surface of the longitudinal beam.

[0072] In the above scheme, by setting the first sub-connection part and the second sub-connection part, and setting the first sub-connection part and the second sub-connection part on both sides of the rib plate respectively, the connection stability between the connection part and the longitudinal beam can be effectively improved, thereby effectively improving the structural stability between the connection part, the rib plate and the mounting beam, effectively reducing the risk of battery falling off, and improving the driving reliability of the vehicle body.

[0073] According to some embodiments of the present application, the bracket includes a plurality of mounting units, which are spaced apart along the longitudinal direction of the frame; the bracket also includes a connecting beam, which extends along the longitudinal direction of the frame and connects two adjacent mounting units.

[0074] In the above scheme, on the one hand, by providing multiple mounting units to support multiple batteries, the purpose of on-demand battery replacement can be achieved, thereby reducing the cost of battery replacement. On the other hand, by providing a connecting beam to connect two adjacent mounting units, the structural stability between the two adjacent mounting units can be effectively improved, the battery carrying capacity can be increased, the risk of battery detachment can be reduced, and the driving reliability of the vehicle body can be improved.

[0075] According to some embodiments of the present application, each mounting unit includes two connecting parts, which are arranged at intervals along the transverse direction of the frame, a pair of longitudinal beams are located between the two connecting parts, and each connecting part is connected to the outer side surface of the corresponding longitudinal beam.

[0076] In the above scheme, by providing two connecting parts, on the one hand, the connecting parts can be connected to the outer side surfaces of the corresponding longitudinal beams, that is, the two longitudinal beams of the frame are respectively connected by the corresponding connecting parts, so that there is a stable connection relationship between the mounting unit and the frame, reducing the risk of battery falling off and improving the reliability of vehicle driving; on the other hand, since two connecting parts are provided and the two connecting parts are arranged at intervals along the lateral direction of the frame, that is, the mounting beam can be provided with more first mounting parts to mount larger batteries, thereby effectively improving the vehicle's endurance.

[0077] According to some embodiments of the present application, the bracket includes a plurality of mounting units, which are spaced apart along the longitudinal direction of the vehicle frame, and a receiving space is formed between two adjacent mounting units, and each receiving space is used to receive a battery.

[0078] In the above scheme, by arranging multiple mounting units at longitudinal intervals of the frame to form multiple accommodating spaces arranged longitudinally along the frame, each battery can be installed in the corresponding accommodating space in an orderly manner, and the batteries do not interfere with each other, thereby improving the battery replacement efficiency of the vehicle body.

[0079] According to some embodiments of the present application, each mounting unit includes a connecting portion; there are two brackets, and a pair of longitudinal beams are located between the two brackets along the transverse direction of the frame.

[0080] 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 side of one of the longitudinal beams through a connecting portion, that is, it can stably position a bracket on the outside of one of the longitudinal beams in the frame. On the other hand, by providing brackets on both sides of the frame, more batteries can be carried, increasing the upper limit of the number of battery replacement batteries, thereby improving the vehicle's range.

[0081] According to some embodiments of the present application, the bracket includes a plurality of mounting units, which are spaced apart along the longitudinal direction of the vehicle frame, and a space for accommodating a battery is formed between two adjacent mounting units.

[0082] In the above solution, multiple mounting units arranged on the bracket in the longitudinal direction of the frame can create multiple spaces to accommodate batteries, reducing the risk of batteries occupying external space and causing space waste. In some embodiments, when the batteries are arranged in the longitudinal direction of the frame, multiple batteries can be arranged in the transverse direction of the frame. The spaces formed by multiple mounting units in a single frame can collectively accommodate at least one column of batteries. In some embodiments, when the batteries are arranged in the transverse direction of the frame, the batteries can be shared by both frames.

[0083] According to some embodiments of the present application, the vehicle frame further comprises a crossbeam connected between the pair of longitudinal beams, and the crossbeam is provided with a second mounting portion, which is detachably connected to the battery.

[0084] In the above solution, by providing a second mounting portion on the crossbeam, a mounting point is created between the battery and the crossbeam, improving the stability of the connection between the battery and the vehicle body and reducing the risk of battery detachment. In some embodiments, when the batteries are arranged longitudinally along the frame, multiple batteries can be arranged transversely along the frame. By providing a second mounting portion on the crossbeam, the corresponding position of the crossbeam can support at least one column of batteries. In some embodiments, when the batteries are arranged transversely along the frame, the batteries can be supported by both the first mounting portions on the two frames and the mounting portion on the crossbeam.

[0085] According to some embodiments of the present application, the bracket assembly further includes a reinforcing plate connected to the crossbeam, and the reinforcing plate is provided with a through hole corresponding to the second mounting portion.

[0086] In the above solution, by providing a reinforcing plate, the structural strength of the beam can be effectively improved, the risk of the beam being damaged due to carrying batteries can be reduced, and the connection stability between the beam and the battery can be improved.

[0087] According to some embodiments of the present application, the mounting beam is a square tube.

[0088] In the above solution, by setting the mounting beam as a square tube, on the one hand, the material cost is low, and on the other hand, the material structure strength is high, which can effectively carry the battery and reduce the risk of the battery falling off.

[0089] According to some embodiments of the present application, along the lateral direction of the frame, a projection of the bracket at least partially overlaps with a projection of the frame.

[0090] In the above direction, the lateral direction of the frame can be perpendicular to the driving mode of the vehicle body. By setting the projection of the bracket to at least partially overlap with the projection of the frame, the ground clearance of the bracket can be effectively increased, the impact of the installation of the bracket on the ground clearance of the vehicle body can be reduced, and the driving reliability of the vehicle body can be improved.

[0091] According to some embodiments of the present application, the bracket has an upwardly open avoidance groove, and at least a portion of the vehicle frame is accommodated in the avoidance groove.

[0092] In the above solution, by providing an avoidance groove on the bracket, at least part of the frame can be avoided, so as to reasonably utilize the space where at least part of the frame is located and reduce the impact of the bracket on the ground clearance of the vehicle body.

[0093] According to some embodiments of the present application, the vehicle frame is connected to the groove bottom wall and / or groove side wall of the avoidance groove.

[0094] In the above scheme, since at least part of the frame is accommodated in the avoidance groove, the frame can be connected to the bottom wall and / or side wall of the avoidance groove, and the avoidance groove can be reasonably utilized so that the avoidance groove can not only avoid the bracket, but also realize the connection between the bracket and the frame, simplifying the connection structure between the bracket and the frame, reducing the installation difficulty and reducing the installation cost.

[0095] According to some embodiments of the present application, the first connector is mounted on the bracket assembly.

[0096] In the above solution, by installing the first connector on the bracket assembly, when the battery is installed on the bracket assembly, the first connector and the second connector can be docked at the same time, thereby improving the battery replacement efficiency.

[0097] According to some embodiments of the present application, the vehicle body includes a cargo box, and the bracket assembly is located below the cargo box.

[0098] In the above solution, the vehicle body can be a freight vehicle body, which can include a cargo box for carrying cargo. For example, the vehicle body can be the body of a heavy-duty truck. By arranging the bracket assembly below the cargo box, the space below the cargo box can be rationally utilized. Compared with the current backpack-style battery replacement of heavy-duty trucks (where the battery is installed on the back of the heavy-duty truck cab), the battery layout of the vehicle body is changed, which can effectively save space in the longitudinal direction of the vehicle, reduce the space occupied by the cargo box, and increase the vehicle's cargo capacity.

[0100] In the above scheme, a vehicle is provided, in which the vehicle body can replace batteries on demand, that is, the number of replacement batteries is adjusted according to its own endurance requirements to achieve the purpose of reducing battery replacement costs.

[0101] According to some embodiments of the present application, the battery has an escape space for evading the bracket assembly.

[0102] In the above solution, by providing an avoidance space on the battery, the space where the bracket assembly is located can be reasonably utilized, the battery capacity can be increased, and a longer driving range can be provided for the vehicle.

[0103] According to some embodiments of the present application, the bracket assembly includes a vehicle frame. Along a lateral direction of the vehicle frame, a projection of the battery at least partially overlaps with a projection of the vehicle frame.

[0104] In the above solution, the transverse direction of the vehicle frame can be perpendicular to the vehicle's travel direction, and can also be understood as the width of the vehicle. By arranging the battery so that its projection at least partially overlaps with the projection of the frame along the transverse direction of the vehicle frame, the battery can effectively utilize the height space of the vehicle body, thereby increasing the battery capacity and providing a longer driving range for the vehicle.

[0105] According to some embodiments of the present application, the bracket assembly includes a vehicle frame. The battery includes a box and a plurality of battery cells disposed in the box, and along the lateral direction of the vehicle frame, the projections of at least some of the battery cells overlap with the projection of the vehicle frame.

[0106] In the above solution, the transverse direction of the vehicle frame can be perpendicular to the vehicle's travel direction, and can also be understood as the width of the vehicle. By arranging at least a portion of the battery cells in the transverse direction of the vehicle frame so that their projections at least partially overlap with the projections of the vehicle frame, the at least portion of the battery cells can effectively utilize the height space of the vehicle body, thereby increasing the battery capacity and providing a longer driving range for the vehicle.

[0107] According to some embodiments of the present application, the lowest point of the battery is lower than the lowest point of the bracket.

[0108] In the above solution, by setting the lowest point of the battery to be lower than the lowest point of the bracket, the battery can reasonably utilize the height space of the vehicle body, thereby increasing the battery capacity and providing the vehicle with a longer driving range.

[0109] According to some embodiments of the present application, the vehicle is a heavy truck.

[0110] A heavy-duty truck can be a heavy-duty truck. When transporting different goods or on different transportation routes, the required battery capacity is different (for example, one battery is needed under short-distance conditions, two batteries are needed under medium-distance conditions, and three batteries are needed under long-distance conditions). Through the vehicle body provided above, on-demand battery replacement can be achieved (for example, for short-distance conditions, only one battery is replaced, that is, one battery is carried; for medium-distance conditions, only two batteries are replaced, that is, two batteries are carried; for long-distance conditions, three batteries are replaced, that is, three batteries are carried), thereby saving the cost of additional batteries and effectively reducing the cost of battery replacement.

DETAILED DESCRIPTION

[0131] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0132] Unless otherwise defined, all technical and scientific terms used in this application have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first" and "second" in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, rather than to describe a specific order or a primary-secondary relationship.

[0133] References to "embodiments" in this application mean that a particular feature, structure, or characteristic described in connection with the embodiment may be included in at least one embodiment of the application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described in this application may be combined with other embodiments.

[0134] In the description of this application, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connected," and "attached" should be understood in a broad sense. For example, they may refer to fixed connections, detachable connections, or integral connections; they may refer to direct connections, indirect connections through an intermediate medium, or internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0135] The term "and / or" in this application simply describes an association between related objects, indicating that three possible relationships exist. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in this application generally indicates that the related objects are in an "or" relationship.

[0136] The term "multiple" in this application refers to more than two (including two). Similarly, "multiple groups" refers to more than two groups (including two groups), and "multiple pieces" refers to more than two pieces (including two pieces).

[0137] In some embodiments, the battery may be a battery module. When there are multiple battery cells, the multiple battery cells are arranged and fixed to form a battery module.

[0138] In some embodiments, the battery may be a battery pack, which includes a case and battery cells, wherein the battery cells or battery modules are housed in the case.

[0139] In some embodiments, the battery cells may be secondary batteries, which are batteries that can be recharged to activate their active materials after discharge and continue to be used. The battery cells may be lithium-ion batteries, sodium-ion batteries, sodium-lithium-ion batteries, lithium metal batteries, sodium metal batteries, lithium-sulfur batteries, magnesium-ion batteries, nickel-metal hydride batteries, nickel-cadmium batteries, lead-acid batteries, and the like, although this disclosure is not intended to limit this.

[0140] At present, new energy vehicles often use battery replacement to timely supplement the power loss of new energy vehicles during driving. For new energy vehicles, how to reduce the cost of battery replacement is a technical problem that needs to be solved urgently. At present, new energy vehicles are equipped with a whole battery. The capacity of this whole battery is fixed, that is, the cruising range of this new energy vehicle is fixed. When replacing the battery, the whole battery will be replaced. However, for different cruising range requirements, the required battery capacity is different. If a shorter cruising range is required, only a battery with a smaller capacity is needed. If a larger battery is configured, it is necessary to pay the battery cost brought by the additional capacity, and then when replacing the battery, the cost of battery replacement is higher.

[0141] In view of this, to address the high cost of battery replacement due to varying battery life requirements, some embodiments of the present application provide a vehicle body comprising a bracket assembly and a plurality of first connectors. The bracket assembly is provided with a plurality of first mounting portions for detachably connecting a corresponding number of batteries. The plurality of first connectors are provided for connecting to a corresponding number of second connectors of the batteries.

[0142] In the above scheme, by setting multiple groups of first mounting parts and multiple first connectors, the number of batteries that need to be replaced can be adjusted based on the battery life requirements (that is, battery replacement on demand, for example, when the required battery life is shorter, a smaller number of batteries can be installed on a corresponding number of first mounting parts in the multiple groups of first mounting parts, and the second connector of each battery is connected to the corresponding first connector; when the required battery life is longer, a larger number of batteries can be installed on a corresponding number of first mounting parts in the multiple groups of first mounting parts, and the second connector of each battery is connected to the corresponding first connector), thereby saving the cost of additional batteries and effectively reducing the cost of battery replacement.

[0143] The vehicle body disclosed in the embodiments of the present application may be used, but is not limited to, in the vehicle body of a passenger vehicle, the vehicle body of a commercial freight vehicle, and the body of a vehicle of other nature. The vehicle body disclosed in the embodiments of the present application may be used, but is not limited to, in the vehicle body of a passenger vehicle, the vehicle body of a commercial freight vehicle, and the body of a vehicle of other nature.

[0144] Please refer to Figure 1, which is a structural diagram of a vehicle 10000 provided in some embodiments of the present application. The vehicle 10000 may be a new energy vehicle, which may be a pure electric vehicle, a hybrid electric vehicle with a replaceable battery, or an extended-range vehicle with a replaceable battery, etc. The vehicle 10000 includes a vehicle body 1000 and a battery 2000. The battery 2000 may be arranged at the bottom, head, or tail of the vehicle body 1000. The battery 2000 may be used to power the vehicle 10000. For example, the battery 2000 may be used as an operating power source for the vehicle 10000, for the circuit system of the vehicle 10000, such as for the working power requirements for starting, navigating, and operating the vehicle 10000.

[0145] The vehicle body 1000 may further include a controller 3000 and a motor 4000 . The controller 3000 is used to control the battery 2000 to supply power to the motor 4000 , for example, to meet the power requirements for starting, navigating, and driving the vehicle 10000 .

[0146] In some embodiments of the present application, the battery 2000 can not only serve as the operating power source of the vehicle 10000, but also serve as the driving power source of the vehicle 10000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 10000.

[0147] Some embodiments of the present application provide a vehicle body 1000. Please refer to Figures 2 and 3. Figure 2 shows a top view of a partial structure of the vehicle body 1000 in some embodiments of the present application. Figure 3 is a schematic diagram of the bracket assembly 100 and the battery 2000 in some embodiments of the present application.

[0148] The vehicle body 1000 includes a bracket assembly 100 and a plurality of first connectors 200. The bracket assembly 100 is provided with multiple sets of first mounting portions 300, each set of first mounting portions 300 being used to detachably connect to a battery 2000. The number of first connectors 200 is equal to the number of sets of first mounting portions 300, and each first connector 200 is used to connect to the second connector of a battery 2000.

[0149] The bracket assembly 100 is a component for mounting the battery 2000. In the vehicle body 1000, the bracket assembly 100 can be set at any position of the vehicle body 1000, for example, the bracket assembly 100 can be set at the back of the cab of the vehicle body 1000, the front of the vehicle body 1000, the rear of the vehicle body 1000, or the bottom of the vehicle body 1000.

[0150] In some embodiments, the bracket assembly 100 is the main structure of the vehicle body 1000 to achieve the battery replacement function. The first mounting part 300 is a component provided on the bracket assembly 100 for detachably connecting to the battery 2000. The first mounting parts 300 are arranged in groups, and each group of first mounting parts 300 corresponds to a battery 2000, which is used to detachably install a corresponding battery 2000 on the bracket assembly 100. The bracket assembly 100 is provided with multiple groups of first mounting parts 300, that is, the bracket assembly 100 can be detachably connected to a corresponding number of batteries 2000 through multiple groups of first mounting parts 300 to achieve the battery replacement function of multiple batteries 2000. In some embodiments, the first mounting part 300 includes but is not limited to mounting holes, mounting screws and other structures that can achieve detachable connection with the battery 2000. In some embodiments, the number of groups of the first mounting parts 300 of the bracket assembly 100 can be two groups, three groups, four groups or more groups.

[0151] In some embodiments, the first connector 200 is a component that connects to the second connector of the 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, high- and low-voltage connectors for connecting to the battery 2000 or a liquid cooling connector for connecting to the battery 2000. In some embodiments, the high- and low-voltage connectors can be electrically connected to the battery 2000 to enable input or output of the battery 2000, as well as input or output of electrical signals. The liquid cooling connector can be used to input or output a heat exchange medium from the battery 2000 to provide thermal management for the battery 2000.

[0152] "The number of first connectors 200 is equal to the number of groups of first mounting parts 300" can be understood as that the vehicle body 1000 can replace the battery on demand. No matter how many batteries 2000 are mounted on the bracket assembly 100 through the first mounting part 300, each battery 2000 can be connected to the corresponding first connector 200, so that each battery 2000 can work normally and charge and discharge normally. For example, based on the endurance requirements of the vehicle 10000, it can be divided into short-distance endurance requirements, medium-distance endurance requirements and long-distance endurance requirements. Short-distance endurance requirements can correspond to one battery 2000; medium-distance endurance requirements correspond to two batteries 2000; long-distance endurance requirements correspond to three batteries 2000. For this reason, the bracket assembly 100 can be provided with three groups of first mounting parts 300, so as to be able to mount up to three batteries 2000 to meet the longest endurance requirements. When short-distance battery life is required, only one battery 2000 can be mounted, and the second connector of the battery 2000 is connected to one first connector 200. When medium-distance battery life is required, only two batteries 2000 can be mounted, and the second connectors of the two batteries 2000 are respectively connected to two first connectors 200. When long-distance battery life is required, three batteries 2000 can be mounted, and the second connector of each battery 2000 is connected to the corresponding first connector 200.

[0153] In the above scheme, the vehicle body 1000 includes a bracket assembly 100 and a plurality of first connectors 200. By providing a plurality of first connectors 200 and providing 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 based on the endurance requirement (that is, replacement on demand, for example, when the endurance is shorter, a smaller number of batteries 2000 can be installed on a corresponding number of first mounting parts 300 in a plurality of first mounting parts 300, and the second connector of each battery 2000 is connected to the corresponding first connector 200; when the endurance is longer, a larger number of batteries 2000 can be installed on a corresponding number of first mounting parts 300 in a plurality of first mounting parts 300, and the second connector of each battery 2000 is connected to the corresponding first connector 200), thereby saving the cost of additional batteries 2000 and effectively reducing the cost of battery replacement.

[0154] According to some embodiments of the present application, the bracket assembly 100 includes a vehicle frame 20 .

[0155] In some embodiments, the vehicle frame 20 may be a frame-like structure spanning the front and rear axles of the vehicle body 1000, commonly known as a beam, and serves as the base of the vehicle body 1000. The functions of the vehicle frame 20 may include supporting and connecting the various assemblies of the vehicle body 1000, ensuring that the assemblies maintain their relative correct positions, and bearing various loads inside and outside the vehicle body 1000.

[0156] In some embodiments, the frame 20 is located at the bottom of the vehicle body 1000 .

[0157] In the above scheme, the frame 20 can be provided with a first mounting portion 300, which can, on the one hand, stably carry the battery 2000, improve the connection stability between the battery 2000 and the vehicle body 1000, and reduce the risk of the battery 2000 falling off; on the other hand, the frame 20 is located at the bottom of the vehicle body 1000, so the battery 2000 can be replaced from the bottom of the vehicle body 1000. Compared with the current backpack-type battery replacement of heavy trucks (the battery 2000 is installed on the back of the cab of the heavy truck), the position layout of the battery 2000 of the vehicle body 1000 is changed, which can effectively save space in the length direction of the vehicle 10000, so as to increase the cargo capacity of the vehicle 10000.

[0158] According to some embodiments of the present application, referring to FIG. 2 and FIG. 3 , the bracket assembly 100 further includes a bracket 10 , which is fixedly connected to the vehicle frame 20 , and the bracket 10 is provided with a first mounting portion 300 .

[0159] The bracket 10 is a component fixed to the frame 20. In some embodiments, the bracket 10 can be connected to the frame 20 by welding, riveting, threading, etc. In other embodiments, the bracket 10 can be integrally formed with the frame 20.

[0160] The bracket 10 is provided with a first mounting portion 300 for mounting the battery 2000. In some embodiments, the bracket 10 has a certain structural strength to be able to mount the battery 2000. In some embodiments, the material of the bracket 10 can be the same as that of the frame 20. In some embodiments, the material of the bracket 10 can be aluminum alloy, steel, cast iron, or reinforced plastic.

[0161] In the above scheme, by fixedly connecting the bracket 10 to the frame 20, on the one hand, the impact of the arrangement of the bracket 10 on the structural reliability of the vehicle body 1000 can be reduced; on the other hand, the bracket 10 can be stably placed in the vehicle body 1000 to effectively carry the battery 2000; on the other hand, the bracket 10 can be added to the frame 20 of the current vehicle body 1000, and the installation is easy and efficient, and can quickly enable the current vehicle 10000 to have the function of on-demand battery replacement.

[0162] According to some embodiments of the present application, please refer to Figure 4, which is a front view of the bracket assembly 100 and the battery 2000 in some embodiments of the present application.

[0163] The vehicle frame 20 includes a first longitudinal beam 21 and a second longitudinal beam 22 . The highest point of the bracket 10 is not higher than the upper end surface of the first longitudinal beam 21 , and the highest point of the bracket 10 is not higher than the upper end surface of the second longitudinal beam 22 .

[0164] In some embodiments, the vehicle body 1000 can be applied to a commercial truck (e.g., a heavy truck) or a passenger vehicle (e.g., a bus), and the vehicle frame 20 can include a first longitudinal beam 21 and a second longitudinal beam 22. The first longitudinal beam 21 and the second longitudinal beam 22 can be spaced apart from each other, and the direction in which the first longitudinal beam 21 and the second longitudinal beam 22 are spaced apart from each other can be the width direction of the vehicle body 1000, and the direction in which the first longitudinal beam 21 and the second longitudinal beam 22 extend can be the length direction of the vehicle body 1000.

[0165] "The highest point of the bracket 10 is not higher than the upper end surface of the first longitudinal beam 21" can be understood as meaning that along the height direction (perpendicular to the ground, generally when the vehicle 10000 is traveling on the ground), the part of the bracket 10 farthest from the ground is not higher than the part of the first longitudinal beam 21 farthest from the ground, that is, no part of the bracket 10 extends beyond the first longitudinal beam 21. "The highest point of the bracket 10 is not higher than the upper end surface of the second longitudinal beam 22" can be understood as meaning that along the height direction, the part of the bracket 10 farthest from the ground is not higher than the part of the second longitudinal beam 22 farthest from the ground, that is, no part of the bracket 10 extends beyond the second longitudinal beam 22.

[0166] In the above solution, the vehicle frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 in a beam. For example, the vehicle frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 in a beam of a large vehicle 10000 (such as a heavy truck). By arranging the bracket 10 on the vehicle frame 20 and not exceeding the upper end surfaces of the first longitudinal beam 21 and the second longitudinal beam 22, the space above the first longitudinal beam 21 and the second longitudinal beam 22 can be saved. On the one hand, the interference with the interior of the vehicle body 1000 caused by the installation of the bracket 10 can be reduced; on the other hand, with respect to the current vehicle body 1000 being equipped with the bracket 10, the difficulty of strengthening the bracket 10 is low and the feasibility is strong; on the other hand, when the battery 2000 is installed on the bracket 10, or the first longitudinal beam 21 and the second longitudinal beam 22, the battery 2000 can be replaced from the bottom of the vehicle body 1000. Compared with the current backpack-type battery replacement of heavy trucks (the battery 2000 is installed on the back of the cab of the heavy truck), the position layout of the battery 2000 of the vehicle body 1000 is changed, which can effectively save space in the length direction of the vehicle 10000, so as to increase the cargo capacity of the vehicle 10000.

[0167] According to some embodiments of the present application, referring to FIG. 3 and FIG. 4 , along the direction from the first longitudinal beam 21 to the second longitudinal beam 22 , the bracket 10 extends beyond the second longitudinal beam 22 .

[0168] In some embodiments, the direction from the first longitudinal beam 21 to the second longitudinal beam 22 may be parallel to the width direction of the vehicle body 1000 , that is, perpendicular to the driving direction of the vehicle 10000 .

[0169] “The bracket 10 extends beyond the second longitudinal beam 22 along the direction from the first longitudinal beam 21 to the second longitudinal beam 22 ” can be understood as that part of the bracket 10 is located on the side of the second longitudinal beam 22 away from the first longitudinal beam 21 , or that part of the bracket 10 is located outside the vehicle frame 20 .

[0170] In the above solution, by setting the bracket 10 to extend beyond the second longitudinal beam 22, a larger installation location can be provided for the battery 2000, so that more batteries 2000 or larger batteries 2000 can be replaced to adapt to different endurance requirements of vehicles 10000 or different endurance requirements of vehicles 10000.

[0171] In some other embodiments, the bracket 10 may not extend beyond the second longitudinal beam 22 . For example, the bracket 10 is located between the first longitudinal beam 21 and the second longitudinal beam 22 .

[0172] According to some embodiments of the present application, referring to FIG. 3 , at least one first mounting portion 300 is provided on a portion of the bracket 10 extending beyond the second longitudinal beam 22 .

[0173] The phrase "at least one first mounting portion 300 is provided on the portion of the bracket 10 extending beyond the second longitudinal beam 22" can be understood as meaning that at least one first mounting portion 300 in a group or each group of first mounting portions 300 is provided on the portion of the bracket 10 extending beyond the second longitudinal beam 22. In some embodiments, the portion of the bracket 10 extending beyond the second longitudinal beam 22 may be provided with multiple first mounting portions 300, each of which may be the first mounting portion 300 in multiple groups of first mounting portions 300. In some embodiments, the portion of the bracket 10 extending beyond the second longitudinal beam 22 may be provided with multiple first mounting portions 300, each of which may be the first mounting portion 300 in a group of mounting portions. In some embodiments, the portion of the bracket 10 extending beyond the second longitudinal beam 22 may be provided with one first mounting portion 300, each of which may be the first mounting portion 300 in a group of mounting portions. In some embodiments, one first mounting portion 300 in each group of first mounting portions 300 may be provided on the portion of the bracket 10 extending beyond the second longitudinal beam 22.

[0174] In the above solution, by providing at least one first mounting portion 300 on the portion of the bracket 10 that extends beyond the second longitudinal beam 22, the portion of the battery 2000 that extends beyond the second longitudinal beam 22 can be connected, so that the battery 2000 is stably connected to the bracket 10, thereby improving the structural stability of the battery 2000 and the bracket 10.

[0175] According to some embodiments of the present application, along the direction from the second longitudinal beam 22 to the first longitudinal beam 21 , the bracket 10 extends beyond the first longitudinal beam 21 .

[0176] In some embodiments, the direction in which the second longitudinal beam 22 points toward the first longitudinal beam 21 may be parallel to the width direction of the vehicle body 1000 , that is, perpendicular to the driving direction of the vehicle 10000 .

[0177] “The bracket 10 extends beyond the first longitudinal beam 21 along the direction from the second longitudinal beam 22 to the first longitudinal beam 21 ” can be understood as that part of the bracket 10 is on the side of the first longitudinal beam 21 away from the second longitudinal beam 22 , or that part of the bracket 10 is on the outside of the vehicle frame 20 .

[0178] In the above solution, by setting the bracket 10 to extend beyond the first longitudinal beam 21, a larger installation location can be provided for the battery 2000, so that more batteries 2000 or larger batteries 2000 can be replaced to adapt to different endurance requirements of vehicles 10000 or different endurance requirements of vehicles 10000.

[0179] In some other embodiments, the bracket 10 may not extend beyond the first longitudinal beam 21 . For example, a portion of the bracket 10 is located between the first longitudinal beam 21 and the second longitudinal beam 22 , and a portion of the bracket 10 extends beyond the second longitudinal beam 22 .

[0180] According to some embodiments of the present application, referring to FIG. 3 , at least one first mounting portion 300 is provided on a portion of the bracket 10 extending beyond the first longitudinal beam 21 .

[0181] The phrase "at least one first mounting portion 300 is provided on the portion of the bracket 10 extending beyond the first longitudinal beam 21" can be understood as meaning that at least one first mounting portion 300 in a group or each group of first mounting portions 300 is provided on the portion of the bracket 10 extending beyond the first longitudinal beam 21. In some embodiments, the portion of the bracket 10 extending beyond the first longitudinal beam 21 may be provided with multiple first mounting portions 300, and these multiple first mounting portions 300 constitute the first mounting portions 300 in multiple groups of first mounting portions 300. In some embodiments, the portion of the bracket 10 extending beyond the first longitudinal beam 21 may be provided with multiple first mounting portions 300, and these multiple first mounting portions 300 constitute the first mounting portions 300 in a group of mounting portions. In some embodiments, the portion of the bracket 10 extending beyond the first longitudinal beam 21 may be provided with one first mounting portion 300, and this one first mounting portion 300 constitutes the first mounting portion 300 in a group of mounting portions. In some embodiments, one first mounting portion 300 in each group of first mounting portions 300 may be provided on the portion of the bracket 10 extending beyond the first longitudinal beam 21.

[0182] In the above solution, by providing at least one first mounting portion 300 on the portion of the bracket 10 that extends beyond the first longitudinal beam 21, the portion of the battery 2000 that extends beyond the first longitudinal beam 21 can be connected, so that the battery 2000 is stably connected to the bracket 10, thereby improving the structural stability of the battery 2000 and the bracket 10.

[0183] According to some embodiments of the present application, at least a portion of the bracket 10 is located between the first longitudinal beam 21 and the second longitudinal beam 22 .

[0184] In some embodiments, "at least a portion of the bracket 10 is located between the first longitudinal beam 21 and the second longitudinal beam 22" can be understood as a portion of the bracket 10 is located between the first longitudinal beam 21 and the second longitudinal beam 22, that is, a portion of the bracket 10 can also be on the outside of the first longitudinal beam 21 and / or the second longitudinal beam 22; it can also be understood as the entire bracket 10 is located between the first longitudinal beam 21 and the second longitudinal beam 22.

[0185] In the above embodiment, the center of gravity of the vehicle body 1000 can be located between the first longitudinal beam 21 and the second longitudinal beam 22. Therefore, by positioning at least a portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22, the effect 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. Furthermore, when the battery 2000 is mounted on the bracket 10, a portion of the battery 2000 or a portion of the battery 2000 can be positioned between the first longitudinal beam 21 and the second longitudinal beam 22. This can reduce the effect of the battery 2000 on the center of gravity of the vehicle body 1000, thereby improving the driving stability of the vehicle body 1000.

[0186] In some other embodiments, the bracket 10 may not be located between the first longitudinal beam 21 and the second longitudinal beam 22. For example, the bracket 10 may be arranged on the side of the first longitudinal beam 21 facing away from the second longitudinal beam 22, or the bracket 10 may be arranged on the side of the second longitudinal beam 22 facing away from the first longitudinal beam 21, or there may be two brackets 10, one of which may be arranged on the side of the first longitudinal beam 21 facing away from the second longitudinal beam 22, and the other bracket 10 may be arranged on the side of the second longitudinal beam 22 facing away from the first longitudinal beam 21.

[0187] According to some embodiments of the present application, referring to FIG. 2 , at least one first mounting portion 300 is provided on a portion of the bracket 10 located between the first longitudinal beam 21 and the second longitudinal beam 22 .

[0188] In some embodiments, the number of the first mounting portions 300 provided on the portion of the bracket located between the first longitudinal beam 21 and the second longitudinal beam 22 may be one, two, three or more.

[0189] The phrase "at least one first mounting portion 300 is provided on the portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22" can be understood as meaning that at least one first mounting portion 300 in a group or each group of first mounting portions 300 is provided on the portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22. In some embodiments, the portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22 may be provided with multiple first mounting portions 300, and the multiple first mounting portions 300 are the first mounting portions 300 in multiple groups of first mounting portions 300. In some embodiments, the portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22 may be provided with multiple first mounting portions 300, and the multiple first mounting portions 300 are the first mounting portions 300 in a group of mounting portions. In some embodiments, the portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22 may be provided with one first mounting portion 300, and the one first mounting portion 300 is the first mounting portion 300 in a group of mounting portions. In some embodiments, one first mounting portion 300 in each set of first mounting portions 300 may be disposed at a portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22 .

[0190] In the above solution, by providing at least one first mounting portion 300 on the portion of the bracket 10 located between the first longitudinal beam 21 and the second longitudinal beam 22, the portion of the battery 2000 located between the first longitudinal beam 21 and the second longitudinal beam 22 can be connected, so that the battery 2000 is stably connected to the bracket 10, thereby improving the structural stability of the battery 2000 and the bracket 10.

[0191] According to other embodiments of the present application, please refer to FIG. 5 , which is a schematic diagram of the bracket assembly 100 in other embodiments of the present application.

[0192] The vehicle frame 20 is provided with a second mounting portion 301 , and the second mounting portion 301 is used for detachably connecting the battery 2000 .

[0193] The second mounting portion 301 is a component provided on the vehicle frame 20 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 can have the same structure as the first mounting portion 300.

[0194] In some embodiments, multiple groups of second mounting parts 301 can be set on the frame 20, and the number of groups of second mounting parts 301 corresponds to the number of groups of first mounting parts 300, so that each battery 2000 can be connected by one group of first mounting parts 300 and one group of second mounting parts 301.

[0195] In the above scheme, by providing a second mounting portion 301 on the frame 20 to detachably connect the battery 2000, and cooperating with the first mounting portion 300 to detachably connect the battery 2000, the connection stability between the battery 2000 and the vehicle body 1000 can be improved, and the driving reliability of the vehicle body 1000 can be improved.

[0196] According to some embodiments of the present application, the vehicle frame 20 includes a first longitudinal beam 21 and a second longitudinal beam 22 , and the second mounting portion 301 is disposed on the first longitudinal beam 21 and / or the second longitudinal beam 22 .

[0197] In some embodiments, the vehicle body 1000 may be applied to a commercial truck (eg, a heavy truck) or a passenger vehicle (eg, a bus), and the frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 .

[0198] In some embodiments, the second mounting portion 301 may be disposed on the first longitudinal beam 21. In some embodiments, the second mounting portion 301 may be disposed on the second longitudinal beam 22. In some embodiments, the second mounting portion 301 may be disposed on both the first longitudinal beam 21 and the second longitudinal beam 22.

[0199] In the above embodiment, the vehicle frame 20 may include the first longitudinal beam 21 and the second longitudinal beam 22 of a beam. For example, the vehicle frame 20 may include the first longitudinal beam 21 and the second longitudinal beam 22 of a beam of a large vehicle 10000 (such as a heavy truck). By disposing the second mounting portion 301 on the first longitudinal beam 21 and / or the second longitudinal beam 22, the second mounting portion 301 can effectively cooperate with the first mounting portion 300, 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.

[0200] According to some embodiments of the present application, the vehicle frame 20 includes a first longitudinal beam 21 , a second longitudinal beam 22 and a cross beam 23 . The cross beam 23 is connected between the first longitudinal beam 21 and the second longitudinal beam 22 , and the second mounting portion 301 is disposed on the cross beam 23 .

[0201] In some embodiments, the first longitudinal beams 21 and the second longitudinal beams 22 are spaced apart from each other, and the cross beam 23 is located in the gap formed by the first and second longitudinal beams 21, 22. The cross beam 23 connects the first and second longitudinal beams 21, 22. The cross beam 23 can improve the structural strength of the vehicle frame 20, allowing the frame 20 to effectively withstand various loads inside and outside the vehicle body 1000.

[0202] In the above solution, the vehicle frame 20 may include a first longitudinal beam 21, a second longitudinal beam 22, and a cross beam 23 in the beam. For example, the vehicle frame 20 may include a first longitudinal beam 21, a second longitudinal beam 22, and a cross beam 23 in the beam of a large vehicle 10000 (such as a heavy truck). By arranging the second mounting portion 301 on the cross beam 23, on the one hand, it can effectively cooperate with the first mounting portion 300, so that the battery 2000 is 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; on the other hand, since the cross beam 23 is located in the gap formed between the first longitudinal beam 21 and the second longitudinal beam 22, arranging the second mounting portion 301 on the cross beam 23 can reasonably utilize the space between the first longitudinal beam 21 and the second longitudinal beam 22, reduce the interference of the second mounting portion 301 on the bracket 10, and improve the battery replacement efficiency of the vehicle body 1000.

[0203] According to some embodiments of the present application, referring to FIG. 2 and FIG. 3 , the bracket assembly 100 has a plurality of accommodating spaces 100 a , which are arranged along a first direction, each accommodating space 100 a being used to accommodate a battery 2000 , and each accommodating space 100 a correspondingly provided with a group of first mounting portions 300 .

[0204] In some embodiments, the bracket assembly 100 has a plurality of receiving spaces 100a arranged along a first direction, and the plurality of receiving spaces 100a are independent of each other. Each receiving space 100a can be used to accommodate a battery 2000, and the battery 2000 located in the receiving space 100a can be connected to a set of first mounting portions 300 in the receiving space 100a.

[0205] The arrangement of the plurality of accommodation spaces 100 a along the first direction can be understood as the arrangement of the plurality of batteries 2000 along the first direction.

[0206] In some embodiments, the sizes of the receiving spaces 100a may be the same so that the bracket assembly 100 can accommodate multiple batteries 2000 of the same specifications. In other embodiments, the sizes of the receiving spaces 100a may be different so that the bracket assembly 100 can accommodate multiple batteries 2000 of different specifications.

[0207] In the above scheme, by arranging multiple accommodating spaces 100a in the first direction, and each accommodating space 100a is correspondingly provided with a group of first mounting parts 300, each battery 2000 can be installed in the corresponding accommodating space 100a in an orderly manner, and the batteries 2000 and 2000 do not interfere with each other, thereby improving the battery replacement efficiency of the vehicle body 1000.

[0208] According to some embodiments of the present application, referring to FIG. 3 , the accommodation space 100 a has an opening that opens downward, and the opening is used for allowing the battery 2000 to enter or exit the accommodation space 100 a.

[0209] “The accommodating space 100a has an opening that opens downward” can be understood as the accommodating space 100a having an opening facing the ground. For example, when the vehicle 10000 is supported on the ground, the opening of the accommodating space 100a faces the ground.

[0210] In some embodiments, the battery 2000 can enter or exit the accommodation space 100 a through the opening.

[0211] In some embodiments, a trench may be provided at the battery exchange site, and the battery exchange mechanism may be provided in the trench. When the vehicle body is in the battery exchange position, the trench may be located below the vehicle body, and the battery 2000 enters or leaves the accommodation space 100a through the battery exchange mechanism in the trench.

[0212] In the above scheme, by setting a downwardly open opening, the battery 2000 can be easily entered into or left the accommodating space 100a from the bottom of the vehicle body 1000. Compared with the current backpack-type battery replacement scheme of heavy trucks, on the one hand, it can save space above the frame 20 and reduce the risk of interference with the vehicle body 1000 and damage to the vehicle body 1000 caused by the battery replacement mechanism occupying the space above the frame 20 during battery replacement; on the other hand, it changes the position layout of the battery 2000 of the vehicle body 1000, which can effectively save space in the length direction of the vehicle 10000, so as to increase the cargo capacity of the vehicle 10000.

[0213] According to some embodiments of the present application, referring to FIG. 3 , the first direction is parallel to the longitudinal direction y of the frame.

[0214] The first direction is the arrangement direction of the accommodating spaces 100 a , which can also be understood as the arrangement direction of the batteries 2000 .

[0215] The longitudinal direction y of the frame may be the extension direction of the longitudinal beam in the frame 20 , and the longitudinal direction y of the frame may also be the traveling direction of the vehicle 10000 .

[0216] In some embodiments, referring to FIG3 , the battery 2000 can be in the form of an elongated strip. When the first direction is parallel to the longitudinal direction y of the vehicle frame, the length of the battery 2000 can be perpendicular to the first direction, that is, the length of the battery 2000 can be parallel to the transverse direction x of the vehicle frame. The transverse direction x of the vehicle frame can be the alignment direction of a pair of longitudinal beams in the vehicle frame 20, or the width direction of the vehicle 10000. Referring to FIG3 , three batteries 2000 are arranged along the longitudinal direction y of the vehicle frame.

[0217] In the above embodiment, the longitudinal direction y of the frame can be parallel to the direction of travel of the vehicle body 1000. The longitudinal direction y of the frame can be the direction in which the longitudinal beams in the frame 20 extend. By arranging the first direction parallel to the longitudinal direction y of the frame, that is, arranging the multiple batteries 2000 along the longitudinal direction y of the frame, the center of gravity of the batteries 2000 can be aligned closer to the center of the frame in the transverse direction x. This reduces the impact of the installation of the batteries 2000 on the center of gravity of the vehicle body 1000, thereby enhancing the driving reliability of the vehicle body 1000.

[0218] According to some embodiments of the present application, referring to FIG2 , the vehicle frame 20 includes a first longitudinal beam 21 and a second longitudinal beam 22, and each accommodating space 100a is divided into a first subspace 100b, a second subspace 100c, and a third subspace 100d by the first longitudinal beam 21 and the second longitudinal beam 22. The first subspace 100b is located between the first longitudinal beam 21 and the second longitudinal beam 22, the second subspace 100c is located on the side of the first longitudinal beam 21 away from the second longitudinal beam 22, and the third subspace 100d is located on the side of the second longitudinal beam 22 away from the first longitudinal beam 21.

[0219] In some embodiments, the vehicle body 1000 can be applied to a commercial truck (e.g., a heavy truck) or a passenger vehicle (e.g., a bus), and the vehicle frame 20 can include a first longitudinal beam 21 and a second longitudinal beam 22. The first longitudinal beam 21 and the second longitudinal beam 22 can be spaced apart from each other, and the direction of the relative spacing between the first longitudinal beam 21 and the second longitudinal beam 22 can be the width direction of the vehicle body 1000 or the transverse direction x of the vehicle frame. The first longitudinal beam 21 and the second longitudinal beam 22 can extend in the length direction of the vehicle body 1000.

[0220] In some embodiments, the accommodation space 100a is divided into three subspaces by the first longitudinal beam 21 and the second longitudinal beam 22, including a first subspace 100b, a second subspace 100c, and a second subspace 100c. Each subspace can accommodate a portion of the battery 2000.

[0221] In some embodiments, the first subspace 100b is located between the first longitudinal beam 21 and the second longitudinal beam 22, and the second subspace 100c and the third subspace 100d can be symmetrically arranged based on the center of the first subspace 100b.

[0222] In some embodiments, the sizes of the second subspace 100c and the third subspace 100d may be the same or different. When the sizes of the second subspace 100c and the third subspace 100d are the same, it can be understood that the volume of the portion of the battery 2000 in the second subspace 100c may be equal to the volume of the portion of the battery 2000 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.

[0223] In the above embodiment, the vehicle frame 20 may include the first longitudinal beam 21 and the second longitudinal beam 22 of the main frame. For example, the vehicle frame 20 may include the first longitudinal beam 21 and the second longitudinal beam 22 of the main frame of a large vehicle 10000 (such as a heavy truck). By dividing the accommodation space 100a into a first subspace 100b, a second subspace 100c, and a third subspace 100d based on the first and second longitudinal beams 21 and 22, the weight of the battery 2000 is evenly distributed based on the positions of the first and second longitudinal beams 21 and 22. This can reduce the impact of the installation of the battery 2000 on the center of gravity of the vehicle body 1000, thereby improving the driving reliability of the vehicle body 1000.

[0224] According to some embodiments of the present application, referring to FIG. 2 , the first subspace 100b is correspondingly provided with at least one first mounting portion 300 , the second subspace 100c is correspondingly provided with at least one first mounting portion 300 , and the third subspace 100d is correspondingly provided with at least one first mounting portion 300 .

[0225] Each accommodating space 100a is provided with a set of first mounting portions 300. The phrase "the first subspace 100b is correspondingly provided with at least one first mounting portion 300, the second subspace 100c is correspondingly provided with at least one first mounting portion 300, and the third subspace 100d is correspondingly provided with at least one first mounting portion 300" can be understood as meaning that the portions of the battery 2000 in the first subspace 100b, the second subspace 100c, and the third subspace 100d are each capable of connecting to the corresponding first mounting portion 300.

[0226] In some embodiments, the first subspace 100b is provided with one, two, three, or more first mounting portions 300. The second subspace 100c is provided with one, two, three, or more first mounting portions 300. The third subspace 100d is provided with one, two, three, or more first mounting portions 300.

[0227] In the above scheme, by distributing at least one first mounting portion 300 in the first subspace 100b, the second subspace 100c and the third subspace 100d, the battery 2000 can be effectively connected, so that the battery 2000 can be stably installed on the vehicle body 1000, reducing the risk of the battery 2000 falling off, and making the vehicle body 1000 have higher driving reliability.

[0228] According to some embodiments of the present application, referring to FIG. 3 , at least two first mounting portions 300 are provided in the first subspace 100b , at least two first mounting portions 300 are provided in the second subspace 100c , and at least two first mounting portions 300 are provided in the third subspace 100d .

[0229] “At least two first mounting parts 300 are provided in the first subspace 100b, at least two first mounting parts 300 are provided in the second subspace 100c, and at least two first mounting parts 300 are provided in the third subspace 100d” can be understood as, in the accommodating space 100a, each subspace is provided with at least two first mounting parts 300, that is, a group of first mounting parts 300 includes at least six first mounting parts 300.

[0230] In some embodiments, referring to FIG3 , four first mounting portions 300 are disposed within the first subspace 100b. These four first mounting portions 300 may be disposed on opposite sides of the battery 2000 in the width direction to collectively connect the portion of the battery 2000 within the first subspace 100b. Four first mounting portions 300 are disposed within the second subspace 100c. These four first mounting portions 300 may be disposed on opposite sides of the battery 2000 in the width direction to collectively connect the portion of the battery 2000 within the second subspace 100c. Four first mounting portions 300 are disposed within the third subspace 100d. These four first mounting portions 300 may be disposed on opposite sides of the battery 2000 in the width direction to collectively connect the portion of the battery 2000 within the third subspace 100d.

[0231] In the above scheme, at least two first mounting parts 300 are distributed in the first subspace 100b, the second subspace 100c and the third subspace 100d, that is, at least six first mounting parts 300 are arranged in the accommodating space 100a, and the six first mounting parts 300 are arranged according to the first subspace 100b, the second subspace 100c and the third subspace 100d, which can connect the battery 2000 with uniform force, so that the battery 2000 is stably in the accommodating space 100a, reducing the risk of the battery 2000 falling off, and making the vehicle body 1000 have higher driving reliability.

[0232] According to some embodiments of the present application, referring to FIG. 2 , at least two first mounting portions 300 within the first subspace 100b are disposed on opposite sides of the first subspace 100b along the longitudinal direction y of the vehicle frame. Furthermore, / or, at least two first mounting portions 300 within the second subspace 100c are disposed on opposite sides of the second subspace 100c along the longitudinal direction y of the vehicle frame. Furthermore, / or, at least two first mounting portions 300 within the third subspace 100d are disposed on opposite sides of the third subspace 100d along the longitudinal direction y of the vehicle frame.

[0233] In some embodiments, along the longitudinal direction y of the frame (or along the arrangement direction of the multiple batteries 2000), the multiple first mounting parts 300 in the first sub-space 100b are arranged on both sides of the first sub-space 100b to connect with the parts of the batteries 2000 on both sides of the longitudinal direction y of the frame.

[0234] In some embodiments, along the longitudinal direction y of the frame, or along the arrangement direction of the multiple batteries 2000, the multiple first mounting portions 300 in the second sub-space 100c are arranged on both sides of the second sub-space 100c to connect with the parts of the batteries 2000 on both sides of the longitudinal direction y of the frame.

[0235] In some embodiments, along the longitudinal direction y of the frame, or along the arrangement direction of the multiple batteries 2000, the multiple first mounting portions 300 in the third subspace 100d are arranged on both sides of the third subspace 100d to connect with the parts of the batteries 2000 on both sides of the longitudinal direction y of the frame.

[0236] In the above solution, by arranging at least two first mounting portions 300 in the first subspace 100b on opposite sides of the first subspace 100b along the longitudinal direction of the frame 20, the battery 2000 can be partially connected and constrained on both sides of the longitudinal direction of the frame 20, so that the force on the battery 2000 is uniform, thereby reducing the risk of the battery 2000 falling off; similarly, by arranging at least two first mounting portions 300 in the second subspace 100c on opposite sides of the second subspace 100c along the longitudinal direction of the frame 20, the battery 2000 can be uniformly connected and constrained. 0 is connected and constrained on both sides of the frame 20 in the longitudinal direction, so that the battery 2000 is evenly stressed, reducing the risk of the battery 2000 falling off; similarly, by arranging at least two first mounting portions 300 in the third subspace 100d on opposite sides of the third subspace 100d in the longitudinal direction of the frame 20, the battery 2000 can be connected and constrained on both sides of the frame 20 in the longitudinal direction, so that the battery 2000 is evenly stressed, reducing the risk of the battery 2000 falling off, and making the vehicle body 1000 have higher driving reliability.

[0240] The transverse direction x of the frame can be the direction in which a pair of longitudinal beams in the frame 20 are arranged, or the width direction of the vehicle 10000. In some embodiments, referring to FIG6 , the battery 2000 can be in the form of an elongated strip. When the first direction is parallel to the transverse direction x of the frame, the length direction of the battery 2000 can be perpendicular to the first direction, that is, the length direction of the battery 2000 can be parallel to the longitudinal direction y of the frame. The longitudinal direction y of the frame can be the direction in which the longitudinal beams in the frame 20 extend, or the direction in which the vehicle 10000 travels. Referring to FIG6 , three batteries 2000 are arranged along the transverse direction x of the frame.

The transverse direction x of the frame can be the arrangement direction of the pair of longitudinal beams of the frame 20, and the transverse direction x of the frame can also be understood as the width direction of the vehicle body 1000. By setting the first direction parallel to the transverse direction x of the frame, that is, the multiple batteries 2000 are arranged along the transverse direction x of the frame, battery replacement can be performed along the width direction of the vehicle body 1000. Compared with battery replacement along the length of the vehicle body 1000, the movement path of the battery 2000 can be effectively shortened, thereby improving battery replacement efficiency.

[0242] According to other embodiments of the present application, the frame 20 includes a first longitudinal beam 21 and a second longitudinal beam 22, the number of the accommodating spaces 100a is at least two, at least one accommodating space 100a is located on the side of the first longitudinal beam 21 away from the second longitudinal beam 22, and at least one accommodating space 100a is located on the side of the second longitudinal beam 22 away from the first longitudinal beam 21.

[0243] In some embodiments, the vehicle body 1000 can be applied to a commercial truck (e.g., a heavy truck) or a passenger vehicle (e.g., a bus), and the vehicle frame 20 can include a first longitudinal beam 21 and a second longitudinal beam 22. The first longitudinal beam 21 and the second longitudinal beam 22 can be spaced apart from each other, and the direction of the relative spacing between the first longitudinal beam 21 and the second longitudinal beam 22 can be the width direction of the vehicle body 1000 or the transverse direction x of the vehicle frame. The first longitudinal beam 21 and the second longitudinal beam 22 can extend in the length direction of the vehicle body 1000.

[0244] In some embodiments, the number of the accommodating spaces 100a may be two or more. Some of the accommodating spaces 100a may be arranged on the side of the first longitudinal beam 21 away from the second longitudinal beam 22 , and another part of the accommodating spaces 100a may be arranged on the side of the second longitudinal beam 22 away from the first longitudinal beam 21 .

[0245] In the above embodiment, the vehicle frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 of a beam. For example, the vehicle frame 20 may include the first longitudinal beam 21 and the second longitudinal beam 22 of a beam of a large vehicle 10000 (such as a heavy truck). By providing a receiving space 100a on the side of the first longitudinal beam 21 facing away from the second longitudinal beam 22, and providing a receiving space 100a on the side of the second longitudinal beam 22 facing away from the first longitudinal beam 21, that is, arranging the batteries 2000 on both sides of the vehicle frame 20, the impact of the installation of the batteries 2000 on the center of gravity of the vehicle body 1000 can be reduced, thereby improving the driving reliability of the vehicle body 1000.

[0246] According to some embodiments of the present application, referring to FIG. 6 , the number of the accommodating spaces 100 a is at least three, and at least one accommodating space 100 a is located between the first longitudinal beam 21 and the second longitudinal beam 22 .

[0247] The number of the accommodating spaces 100a is at least three, that is, the bracket 10 can mount at least three batteries 2000. At least one accommodating space 100a is located between the first longitudinal beam 21 and the second longitudinal beam 22, that is, at least one battery 2000 can be located between the first longitudinal beam 21 and the second longitudinal beam 22.

[0248] In the above solution, by arranging the battery 2000 between the first longitudinal beam 21 and the second longitudinal beam 22 , the influence of the installation of the battery 2000 on the center of gravity of the vehicle body 1000 can be reduced, so that the vehicle body 1000 has higher driving reliability.

[0249] According to some embodiments of the present application, please refer to Figure 2 and Figure 6. The first mounting portion 300 is disposed at at least one end of the accommodating space 100a along the first direction.

[0250] “The first mounting portion 300 is provided at at least one end of the accommodating space 100a along the first direction” can be understood as, in the first direction, the first mounting portion 300 is provided at one end of the accommodating space 100a, or the first mounting portions 300 can be provided at opposite ends of the accommodating space 100a respectively.

[0251] In the above solution, by arranging the first mounting portion 300 at at least one end of the accommodating space 100a in the first direction, the connected battery 2000 can be effectively constrained in the first direction, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle body 1000.

[0252] According to some embodiments of the present application, referring to FIG. 2 , the first mounting portions 300 are disposed at opposite ends of the accommodating space 100 a along the first direction.

[0253] In the first direction, both opposite ends of the accommodation space 100a are provided with first mounting portions 300. In some embodiments, the number of first mounting portions 300 provided at the opposite ends of the accommodation space 100a can be the same or different.

[0254] In the above scheme, by arranging the first mounting portion 300 at the opposite end of the accommodating space 100a in the first direction, the connected battery 2000 can be effectively constrained in the first direction, so that the battery 2000 is evenly stressed, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle body 1000.

[0255] According to some embodiments of the present application, referring to FIG. 2 , the accommodating space 100 a has a first end and a second end opposite to each other along a first direction, and the first mounting portion 300 disposed at the first end is staggered with the first mounting portion 300 disposed at the second end.

[0256] The first end and the second end are two opposite portions of the accommodation space 100a in the first direction. In some embodiments, the first end and the second end correspond to two opposite edges of the battery in the first direction.

[0257] "The first mounting portion 300 disposed at the first end is offset from the first mounting portion 300 disposed at the second end" can be understood as meaning that along the first direction, the projection of the first mounting portion 300 disposed at the first end and the projection of the first mounting portion 300 disposed at the second end do not overlap. In other words, when the first mounting portion 300 disposed at the first end is translated along the first direction to the second end, it will not interfere with the first mounting portion 300 disposed at the second end.

[0258] In the above scheme, by staggering the first mounting parts 300 located at opposite ends of the accommodating space 100a, on the one hand, it has a fool-proof effect on the installation of the battery 2000, reducing the risk of incorrect installation of the battery 2000; on the other hand, it has a visual fool-proof effect on the installation of the bracket 10, reducing the risk of incorrect installation of the bracket 10.

[0259] According to some embodiments of the present application, the first mounting portions 300 at the ends of two adjacent accommodating spaces 100 a that are close to each other are staggered.

[0260] "The first mounting portions 300 at the ends of two adjacent storage spaces 100a that are close to each other are staggered" can be understood as the staggered arrangement of the corresponding first mounting portions 300 at the locations where the two batteries 2000 are close to each other in the two adjacent storage spaces 100a. Referring to Figure 2, if the first mounting portion 300 disposed at one end of one storage space 100a near the other storage space 100a is translated along the first direction to the end of the other storage space 100a near the one storage space 100a, it will not interfere with the first mounting portion 300 originally disposed at the end of the other storage space 100a near the one storage space 100a. In other words, the staggered arrangement of the first mounting portions 300 at the ends of two adjacent storage spaces 100a that are close to each other is not only spaced apart from each other in the first direction, but also has a distance perpendicular to the first direction.

[0261] In the above solution, when replacing the battery, multiple battery replacement execution ends (such as battery replacement heads) can simultaneously act on the parts where multiple first mounting parts 300 are connected to the battery 2000. The two adjacent accommodating spaces 100a are close to each other in the first direction. To this end, by staggering the first mounting parts 300 at the ends of the two adjacent accommodating spaces 100a that are close to each other, the risk of interference between the two adjacent battery replacement execution ends can be reduced, allowing multiple battery replacement execution ends to work simultaneously and improve the battery replacement efficiency.

[0262] According to some embodiments of the present application, as shown in Figures 2 and 3, the size of the accommodating 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.

[0263] The first direction may be the direction in which the plurality of receiving spaces 100a are arranged, and the second direction may be a direction perpendicular to the first direction and perpendicular to the direction of gravity z. In some embodiments, when the first direction is the longitudinal direction y of the frame, the second direction may be the lateral direction x of the frame. When the first direction is the lateral direction x of the frame, the second direction may be the longitudinal direction y of the frame.

[0264] In some embodiments, the accommodating space 100a can be a rectangular space, the size of the accommodating space 100a in the first direction is smaller than the size in the second direction, the accommodating space 100a can accommodate a long or rectangular battery 2000, and the size of the battery 2000 in the first direction can be smaller than the size in the second direction.

[0265] In the above solution, the dimension of the accommodating space 100a along the first direction is smaller than the dimension along the second direction. This can be understood as meaning that the dimension of the battery cell accommodated in the accommodating space 100a along the first direction is smaller than the dimension along the second direction. In other words, the dimension of the battery 2000 in the second direction can be the length of the battery 2000. Therefore, when the first mounting portion 300 is disposed at at least one end of the accommodating space 100a along the first direction, it can be understood that the first mounting portion 300 corresponds to the shorter side of the battery 2000, rather than the longer side of the battery 2000. This can reduce the risk of the middle portion of the battery 2000 collapsing under gravity, thereby improving the stability of the connection between the battery 2000 and the bracket 10.

[0266] According to some embodiments of the present application, please refer to Figures 7 and 8. Figure 7 is a schematic diagram of the frame 20 and the bracket 10 in some embodiments of the present application, and Figure 8 is an enlarged view of point A in Figure 7.

[0267] The vehicle frame 20 includes a pair of longitudinal beams. The bracket 10 includes at least one mounting unit 11. Each mounting unit 11 includes a mounting beam 12 and a connecting portion 13. The mounting beam 12 extends in the transverse direction x of the vehicle frame. The connecting portion 13 is connected to the outer side surface of the longitudinal beam frame 20 in the transverse direction x of the vehicle frame. The mounting beam 12 is connected to the connecting portion 13. The mounting beam 12 is provided with a first mounting portion 300.

[0268] In some embodiments, the vehicle body 1000 can be used in a commercial truck (e.g., a heavy truck) or a passenger vehicle (e.g., a bus). The vehicle frame 20 can include a pair of longitudinal beams (e.g., a first longitudinal beam 21 and a second longitudinal beam 22) spaced apart from each other. A transverse direction x of the vehicle frame can be the arrangement direction of the pair of longitudinal beams. In some embodiments, the transverse direction x of the vehicle frame can be the width direction of the vehicle 10000. A longitudinal direction y of the vehicle frame can be the extension direction of the longitudinal beams. In some embodiments, the transverse direction x of the vehicle frame can be the length direction or the travel direction of the vehicle 10000.

[0269] The mounting unit 11 is a unit of the bracket 10 used to mount the battery 2000. The mounting unit 11 includes a mounting beam 12 and a connecting portion 13. The connecting portion 13 is connected to the outer side of the longitudinal beam. The side of the longitudinal beam facing the other longitudinal beam may be the inner side, and the side of the longitudinal beam facing away from the other longitudinal beam may be the outer side. In some embodiments, the connecting portion 13 may be connected to the outer side of the longitudinal beam by welding, screw connection, or other connection methods.

[0270] The mounting beam 12 is a beam structure that may be rod-shaped (see FIG7 ). The mounting beam 12 may extend along the transverse 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 longitudinal beams of the vehicle frame 20. In some embodiments, a portion of the mounting beam 12 may be located between a pair of longitudinal beams of the vehicle frame 20, and the portion of the mounting beam 12 may be located outside one of the longitudinal beams. In some embodiments, a portion of the mounting beam 12 may be located between a pair of longitudinal beams of the vehicle frame 20, and the portion of the mounting beam 12 may be located on both sides of the vehicle frame 20 along the transverse direction x of the vehicle frame.

[0271] The mounting beam 12 may be connected to the vehicle frame 20 .

[0272] The mounting beam 12 is directly or indirectly connected to the connecting portion 13, so that the mounting beam 12 can be connected to the vehicle frame 20. In some embodiments, the mounting beam 12 can be connected to the connecting portion 13 by welding, riveting, screwing, or other connection methods. In some embodiments, the mounting beam 12 and the connecting portion 13 can be integrally formed.

[0273] The mounting beam 12 is provided with a first mounting portion 300. It can be understood that the first mounting portion 300 on the bracket assembly 100 can be provided on the mounting beam 12, and the mounting beam 12 supports the battery 2000 via the first mounting portion 300. In some embodiments, the mounting beam 12 can be connected to the vehicle frame 20, for example, by welding, screwing, or other connection methods.

[0274] In some embodiments, the mounting unit 11 can be used to detachably connect the battery 2000, and the battery 2000 can be located on both sides of the mounting unit 11, for example, on both sides of the mounting unit 11. In some embodiments, the mounting unit 11 can cooperate with the first mounting portion 300 on the frame 20 to jointly carry the battery 2000.

[0275] In the above embodiment, the vehicle frame 20 may include a pair of longitudinal beams from a beam, for example, a pair of longitudinal beams from a beam of a large vehicle 10000 (such as a heavy truck). The provision of the connecting portion 13 effectively connects the mounting beam 12 to the longitudinal beams, allowing the mounting beam 12 to effectively support the battery 2000 via the first mounting portion 300, thereby reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle body 1000.

[0276] According to some embodiments of the present application, the connecting portion 13 extends along the gravity direction z.

[0277] In some embodiments, the gravity direction z is perpendicular to the longitudinal direction y of the frame and the lateral direction x of the frame.

[0278] “The connecting portion 13 extends along the gravity direction z” can be understood as that the connecting portion 13 has a surface parallel to the gravity direction z, and the surface can be attached to the outer side surface of the longitudinal beam.

[0279] In the above scheme, by setting the connecting portion 13 to extend along the gravity direction z, so that the connecting portion 13 has a larger area in the gravity direction z to be connected to the longitudinal beam, the connection stability between the mounting beam 12 and the longitudinal beam is improved, the risk of the battery 2000 falling off is reduced, and the driving reliability of the vehicle body 1000 is improved.

[0280] According to some embodiments of the present application, referring to FIG. 7 and FIG. 8 , the mounting unit 11 further includes a rib 14 , which is located on the outside of the frame 20 along the transverse direction x of the frame, and connects the connecting portion 13 and the mounting beam 12 .

[0281] The ribs 14 connect the connection portion 13 and the mounting beam 12. In some embodiments, the ribs 14 can be used to strengthen the structural strength of the connection portion 13, the mounting beam 12, and the longitudinal beam. In some embodiments, the ribs 14 can be reinforcement bars, reinforcement beams, or reinforcement ribs disposed between the connection portion 13 and the mounting beam 12.

[0282] In some embodiments, the rib 14 can be connected to the connecting portion 13 by welding, screw connection or other connection methods. Or in some embodiments, the rib 14 can be integrally formed with the connecting portion 13. In some embodiments, the rib 14 can be connected to the mounting beam 12 by welding, screw connection or other connection methods. In some embodiments, please refer to Figure 9, which is a schematic diagram of the local structure of the connecting portion 13, the mounting beam 12, the rib 14 and the longitudinal beam in some embodiments of the present application. The rib 14 can be plate-shaped, which can be formed by two plate-like structural members being fitted together, and the two plate-like structural members are respectively formed with flanges 140 at one end facing the mounting beam 12, and the flanges 140 of the two plate-like structural members are folded toward opposite sides to be connected to the mounting beam 12 by welding together or by screw connection.

[0283] In the above scheme, by providing the ribs 14 on the outer side of the frame 20, on the one hand, the space between the connecting portion 13 and the mounting beam 12 can be reasonably utilized, and on the other hand, the structural strength of the connecting portion 13 and the mounting beam 12 can be improved, thereby reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle body 1000.

[0284] In some embodiments, a notch is formed on the end surface of the rib 14 facing the mounting beam 12. The notch corresponds to the first mounting portion 300 on the mounting beam 12. The notch is used to avoid the first mounting portion 300 to reduce the interference caused by the rib 14 on the portion where the battery 2000 and the first mounting portion 300 are connected to each other.

[0285] According to some embodiments of the present application, please refer to Figure 10, which is a schematic diagram of the mounting unit 11 in some embodiments of the present application. The connecting portion 13 includes a first sub-connecting portion 130 and a second sub-connecting portion 131. The first sub-connecting portion 130 and the second sub-connecting portion 131 extend from the edge of the rib 14 in opposite directions, and the first sub-connecting portion 130 and the second sub-connecting portion 131 are both connected to the outer side of the longitudinal beam.

[0286] The first sub-connecting portion 130 is a component that connects the rib 14 to the outer side of the longitudinal beam. In some embodiments, the first sub-connecting portion 130 is plate-shaped, and its surface facing away from the rib 14 can be connected to the outer side of the longitudinal beam by welding, screwing, or other connection methods. The second sub-connecting portion 131 is a component that connects the rib 14 to the outer side of the longitudinal beam. In some embodiments, the second sub-connecting portion 131 is plate-shaped, and its surface facing away from the rib 14 can be connected to the outer side of the longitudinal beam by welding, screwing, or other connection methods.

[0287] “The first sub-connection portion 130 and the second sub-connection portion 131 extend in opposite directions from the edges of the rib 14 respectively” can be understood as, along the thickness direction of the rib 14, or along the longitudinal direction y of the frame, the first sub-connection portion 130 and the second sub-connection portion 131 are located on opposite sides of the rib 14.

[0288] In some embodiments, the number of first sub-connecting parts 130 may be one, while in other embodiments, the number of first sub-connecting parts 130 is multiple, and the multiple first sub-connecting parts 130 are spaced apart along the gravity direction z. In some embodiments, the number of second sub-connecting parts 131 may be one, while in other embodiments, the number of second sub-connecting parts 131 is multiple, and the multiple second sub-connecting parts 131 are spaced apart along the gravity direction z. In some embodiments, the number of first sub-connecting parts 130 is multiple, and the multiple first sub-connecting parts 130 are spaced apart along the gravity direction z. The number of second sub-connecting parts 131 is multiple, and the multiple second sub-connecting parts 131 are spaced apart along the gravity direction z. The first sub-connecting parts 130 and the second sub-connecting parts 131 are staggered.

[0289] In some embodiments, referring to FIG. 9 , the mounting unit 11 may further include a reinforcement sheet 17, comprising a first portion 170, a second portion 171, and a third portion 172. The first portion 170 is connected to the top surface of the longitudinal beam, and 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 disposed opposite each other along the longitudinal direction y of the vehicle frame, forming an escape gap between the second portion 171 and the third portion 172. The escape gap allows the rib 14 to be avoided, allowing the second portion 171 and the third portion 172 to be located on opposite sides of the rib 14. The second portion 171 can contact the first sub-connection portion 130, that is, the first sub-connection portion 130 is located between the second portion 171 and the longitudinal beam, and the third portion 172 can contact the second sub-connection portion 131, that is, the second sub-connection portion 131 is located between the third portion 172 and the longitudinal beam. In some embodiments, the first part 170 is fixed to the top surface of the longitudinal beam by a screw, the second part 171 is connected to the outer side surface of the longitudinal beam by a screw passing through the first sub-connection part 130, and the third part 172 is connected to the outer side surface of the longitudinal beam by a screw passing through the second sub-connection part 131.

[0290] In the above scheme, by setting the first sub-connection part 130 and the second sub-connection part 131, and setting the first sub-connection part 130 and the second sub-connection part 131 on both sides of the rib 14 respectively, the connection stability between the connection part 13 and the longitudinal beam can be effectively improved, thereby effectively improving the structural stability between the connection part 13, the rib 14 and the mounting beam 12, effectively reducing the risk of the battery 2000 falling off, and improving the driving reliability of the vehicle body 1000.

[0291] According to some embodiments of the present application, as shown in FIG7 , a bracket 10 includes a plurality of mounting units 11 spaced apart along the longitudinal direction y of the vehicle frame. The bracket 10 also includes a connecting beam 15 extending along the longitudinal direction y of the vehicle frame to connect two adjacent mounting units 11.

[0292] Referring to FIG7 , multiple mounting units 11 are spaced apart along the longitudinal direction y of the vehicle frame. In some embodiments, the battery 2000 can be located between two adjacent mounting units 11. In some embodiments, the number of mounting units 11 can be two, three, or four. Referring to FIG7 , the number of mounting units 11 is four. In some embodiments, the spacing between two adjacent mounting units 11 can be equal or unequal.

[0293] Please refer to FIG. 7 . The bracket 10 further includes a connecting beam 15 . The connecting beam 15 is a beam structure. The connecting beam 15 connects two adjacent mounting units 11 . Its function may include improving the structural stability of the two mounting units 11 .

[0294] In some embodiments, the connecting beam 15 may be in the shape of a plate, a pipe column, or a rod. In some embodiments, the connecting beam 15 may connect two adjacent mounting units 11 by bonding, welding, riveting, or threading.

[0295] In some embodiments, the connecting beam 15 can connect to the ends of two adjacent mounting beams 12. In some embodiments, the connecting beam 15 can connect to the ends of two adjacent ribs 14. In some embodiments, the connecting beam 15 can connect to the ends of two adjacent connecting portions 13. In some embodiments, there can be multiple connecting beams 15, with some connecting beams 15 connecting to the ends of two adjacent ribs 14, some connecting beams 15 connecting to the ends of two adjacent ribs 14, and some connecting beams 15 connecting to the ends of two adjacent connecting portions 13.

[0296] In the above scheme, on the one hand, by providing multiple mounting units 11 to carry multiple batteries 2000, the purpose of on-demand battery replacement can be achieved, thereby reducing the cost of battery replacement. On the other hand, by providing a connecting beam 15 to connect two adjacent mounting units 11, the structural stability between the two adjacent mounting units 11 can be effectively improved, the carrying capacity of the batteries 2000 can be increased, the risk of the batteries 2000 falling off can be reduced, and the driving reliability of the vehicle body 1000 can be improved.

[0297] According to some embodiments of the present application, please refer to Figures 10 and 11. Figure 11 is a front view of the mounting unit 11 and the longitudinal beam in some embodiments of the present application.

[0298] Each mounting unit 11 includes two connecting parts 13 , which are spaced apart along the transverse direction x of the vehicle frame. A pair of longitudinal beams are located between the two connecting parts 13 , and each connecting part 13 is connected to the outer side surface of the corresponding longitudinal beam.

[0299] The transverse direction x of the vehicle frame can be the arrangement direction of the pair of longitudinal beams. In some embodiments, the pair of longitudinal beams includes a first longitudinal beam 21 and a second longitudinal beam 22. Each mounting unit 11 includes two connecting portions 13 corresponding to the two longitudinal beams, namely, the first longitudinal beam 21 and the second longitudinal beam 22. One connecting portion 13 is connected to the outer side of the first longitudinal beam 21, and the other connecting portion 13 is connected to the outer side of the second longitudinal beam 22.

[0300] Referring to Figure 11 , a portion of the mounting beam 12 may be positioned between a pair of longitudinal beams, while the remaining portion of the mounting beam 12 may be positioned on either side of the pair of longitudinal beams (e.g., a portion of the mounting beam 12 extends beyond the first longitudinal beam 21, and a portion of the mounting beam 12 extends beyond the second longitudinal beam 22). In some embodiments, the portion of the mounting beam 12 positioned between the pair of longitudinal beams may be provided with at least one first mounting portion 300. The portion of the mounting beam 12 extending beyond the first longitudinal beam 21 may be provided with at least one first mounting portion 300. The portion of the mounting beam 12 extending beyond the second longitudinal beam 22 may also be provided with at least one first mounting portion 300.

[0301] In the above scheme, by providing two connecting parts 13, on the one hand, the connecting parts 13 can be connected to the outer side surfaces of the corresponding longitudinal beams, that is, the two longitudinal beams of the frame 20 are respectively connected by the corresponding connecting parts 13, so that there is a stable connection relationship between the mounting unit 11 and the frame 20, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle 10000; on the other hand, since there are two connecting parts 13, and the two connecting parts 13 are arranged at intervals along the transverse x direction of the frame, that is, the mounting beam 12 can be provided with more first mounting parts 300 to mount larger batteries 2000, thereby effectively improving the endurance of the vehicle 10000.

[0302] According to some embodiments of the present application, please refer to Figure 7, the bracket 10 includes a plurality of mounting units 11, and the plurality of mounting units 11 are arranged at intervals along the longitudinal direction y of the frame, and an accommodating space 100a is formed between two adjacent mounting units 11, and each accommodating space 100a is used to accommodate a battery 2000.

[0303] In some embodiments, a plurality of mounting units 11 are spaced apart along the longitudinal direction y of the vehicle frame, and an accommodating space 100 a is formed between two adjacent mounting units 11 .

[0304] In some embodiments, two mounting units 11 are spaced apart along the longitudinal direction y of the frame, and a storage space 100a for accommodating a battery 2000 can be formed between the two mounting units 11. The remaining batteries 2000 can be arranged on the side of one of the mounting units 11 away from the other mounting unit 11.

[0305] In some embodiments, the number of mounting units 11 can be at least three, forming at least two receiving spaces 100a arranged along the longitudinal direction y of the vehicle frame. Each receiving space 100a is independent of each other. Each receiving space 100a can be used to accommodate a battery 2000, and the battery 2000 located in the receiving space 100a can be connected to a set of first mounting portions 300 in the receiving space 100a.

[0306] In the above scheme, by arranging multiple mounting units 11 at intervals in the longitudinal direction y of the frame to form multiple accommodating spaces 100a arranged along the longitudinal direction y of the frame, each battery 2000 can be installed in the corresponding accommodating space 100a in an orderly manner, and the batteries 2000 do not interfere with each other, thereby improving the battery replacement efficiency of the vehicle body 1000.

[0307] According to other embodiments of the present application, please refer to FIG. 12 , which is a schematic diagram of the bracket 10 and the frame 20 in other embodiments of the present application.

[0308] Each mounting unit 11 includes a connecting portion 13. There are two brackets 10, and a pair of longitudinal beams are located between the two brackets 10 along the transverse direction x of the vehicle frame.

[0309] In some embodiments, "each mounting unit 11 includes a connecting portion 13" can be understood as meaning that the mounting unit 11 includes a mounting beam 12 and a connecting portion 13. The mounting beam 12 can be located outside the longitudinal beam, and the connecting portion 13 is located outside the longitudinal beam and connects to the outer side surface of the longitudinal beam. The mounting beam 12 is connected to the connecting portion 13. One bracket 10 can be located on one side of the vehicle frame 20. That is, when there is only one bracket 10 in the vehicle body 1000, the bracket 10 can be located on one side of the vehicle frame 20.

[0310] “There are two brackets 10, and along the transverse direction x of the frame, a pair of longitudinal beams are located between the two brackets 10” can be understood as, there are two brackets 10, and the two brackets 10 are respectively located on both sides of the frame 20, one of the brackets 10 is connected to one of the longitudinal beams of the frame 20, and the other bracket 10 is connected to the other longitudinal beam of the frame 20.

[0311] In the above solution, on the one hand, 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 side of one of the longitudinal beams through a connecting portion 13, that is, it can stably position a bracket 10 on the outer side of one of the longitudinal beams in the frame 20. On the other hand, by arranging brackets 10 on both sides of the frame 20, more batteries 2000 can be carried, thereby increasing the upper limit of the number of battery replacement batteries 2000, and thus improving the endurance of the vehicle 10000.

[0312] According to other embodiments of the present application, please refer to Figure 12, the bracket 10 includes a plurality of mounting units 11, and the plurality of mounting units 11 are arranged at intervals along the longitudinal direction y of the frame, and a space for accommodating the battery 2000 is formed between two adjacent mounting units 11.

[0313] In the longitudinal direction y of the vehicle frame, the bracket 10 includes a plurality of mounting units 11. Mounting beams 12 within the plurality of mounting units 11 are spaced apart, and each mounting beam 12 is connected to a corresponding connecting portion 13. Adjacent mounting units 11 are spaced apart to form a space capable of accommodating a portion of the battery 2000. For example, along the longitudinal direction y of the vehicle frame, the projection of the battery 2000 can overlap with the projection of the mounting beam 12 and / or the connecting portion 13.

[0314] In some embodiments, the bracket 10 may include two, three, or four mounting units 11. Referring to Figure 12, the four mounting units 11 are spaced apart to form three spaces.

[0315] In some embodiments, the battery 2000 can be in the form of an elongated strip or rectangle. The battery 2000 can extend along the longitudinal direction y of the vehicle frame, and each battery 2000 can be mounted on a single bracket 10. Referring to Figure 12 , two brackets 10 are provided on either side of the vehicle frame 20, thereby supporting two batteries 2000, which are arranged along the transverse direction x of the vehicle frame.

[0316] In the above solution, the bracket 10, provided with multiple mounting units 11 in the longitudinal direction y of the frame, can create multiple spaces to accommodate the batteries 2000, reducing the risk of batteries 2000 occupying external space and causing waste. In some embodiments, when the batteries 2000 are arranged along the longitudinal direction y of the frame, the multiple batteries 2000 can be arranged along the transverse direction x of the frame. The spaces formed by the multiple mounting units 11 in a single frame 20 can collectively accommodate at least one column of batteries 2000. In some embodiments, when the batteries 2000 are arranged along the transverse direction x of the frame, the batteries 2000 can be shared by two frames 20.

[0317] According to other embodiments of the present application, please refer to Figure 13, which is a bottom view of the frame 20 and bracket 10 in other embodiments of the present application. The frame 20 also includes a crossbeam 23, which is connected between a pair of longitudinal beams. The crossbeam 23 is provided with a second mounting portion 301, which is detachably connected to the battery 2000.

[0318] In some embodiments, the pair of longitudinal beams includes a first longitudinal beam 21 and a second longitudinal beam 22. The first longitudinal beam 21 and the second longitudinal beam 22 are spaced apart from each other. The cross beam 23 is located in the gap formed by the pair of longitudinal beams and connects the first longitudinal beam 21 and the second longitudinal beam 22. The cross beam 23 can improve the structural strength of the vehicle frame 20, allowing the frame 20 to effectively withstand various loads inside and outside the vehicle body 1000.

[0319] The second mounting portion 301 is a component provided on the crossbeam 23 for detachable connection 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 can have the same structure as the first mounting portion 300.

[0320] In some embodiments, the vehicle frame 20 may have multiple cross beams 23. The multiple cross beams 23 can be provided with multiple sets of second mounting portions 301, where the number of sets of second mounting portions 301 corresponds to the number of sets of first mounting portions 300, so that each battery 2000 can be connected to one set of first mounting portions 300 and one set of second mounting portions 301.

[0321] In the above solution, by providing a second mounting portion 301 on the crossbeam 23, a mounting point is created between the battery 2000 and the crossbeam 23, thereby 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 batteries 2000 are arranged along the longitudinal direction y of the vehicle frame, multiple batteries 2000 can be arranged along the transverse direction x of the vehicle frame. By providing the second mounting portion 301 on the crossbeam 23, at least one column of batteries 2000 can be supported at the corresponding position of the crossbeam 23. In some embodiments, when the batteries 2000 are arranged along the transverse direction x of the vehicle frame, the batteries 2000 can be supported by both the first mounting portions 300 on the two frames 20 and the mounting portion on the crossbeam 23.

[0322] According to other embodiments of the present application, referring to FIG. 13 , the bracket assembly 100 further includes a reinforcing plate 16 . The reinforcing plate 16 is connected to the crossbeam 23 , and the reinforcing plate 16 is provided with a through hole corresponding to the second mounting portion 301 .

[0323] In some embodiments, the reinforcing plate 16 may be plate-shaped and may be disposed on the surface of the beam 23 facing the ground, that is, on the lower surface of the beam 23. The reinforcing plate 16 may have a through hole to avoid the second mounting portion 301 on the beam 23.

[0324] In some embodiments, in the transverse direction x of the vehicle frame, opposite ends of the reinforcement plate 16 may be connected to a pair of longitudinal beams of the vehicle frame 20 , respectively.

[0325] In the above solution, by providing the reinforcing plate 16 , the structural strength of the beam 23 can be effectively improved, the risk of the beam 23 being damaged due to carrying the battery 2000 can be reduced, and the connection stability between the beam 23 and the battery 2000 can be improved.

[0326] According to some embodiments of the present application, referring to FIG. 10 , the mounting beam 12 is a square tube.

[0327] In some embodiments, the square tube may be a tubular structure having a cavity therein. In some embodiments, the square tube may be square steel.

[0328] In the above solution, by setting the mounting beam 12 as a square tube, on the one hand, the material cost is low, and on the other hand, the material structure strength is high, which can effectively carry the battery 2000 and reduce the risk of the battery 2000 falling off.

[0329] According to some embodiments of the present application, referring to FIG. 4 , along the transverse direction x of the frame, the projection of the bracket 10 at least partially overlaps with the projection of the frame 20 .

[0330] The transverse direction x of the vehicle frame can be the alignment direction of the pair of longitudinal beams in the vehicle frame 20, or it can be the width direction of the vehicle 10000. "Along the transverse direction x of the vehicle frame, the projection of the bracket 10 at least partially overlaps with the projection of the vehicle frame 20" can be understood to mean that, in the height direction (i.e., the direction of gravity z), the bracket 10 utilizes the space within the vehicle frame 20. Alternatively, it can be understood that, among brackets 10 of the same specifications, by raising the bracket 10 so that its projection in the transverse direction x of the vehicle frame falls on the vehicle frame 20, the ground clearance of the bracket 10 can be increased.

[0331] In the above direction, the lateral direction x of the frame can be perpendicular to the driving mode of the vehicle body 1000. By setting the projection of the bracket 10 to at least partially overlap with the projection of the frame 20, the ground clearance of the bracket 10 can be effectively increased, the impact of the installation of the bracket 10 on the ground clearance of the vehicle body 1000 can be reduced, and the driving reliability of the vehicle body 1000 can be improved.

[0332] According to some embodiments of the present application, please refer to Figure 14, which is a front view of the bracket 10 and the frame 20 in some embodiments of the present application. The bracket 10 has an upwardly open avoidance groove 10a, and at least a portion of the frame 20 is accommodated in the avoidance groove 10a.

[0333] In some embodiments, “open upward” may mean that when the vehicle body 1000 is located on the ground, the bracket 10 can be installed from below the vehicle frame 20 .

[0334] In some embodiments, the bracket 10 has an avoidance groove 10a, which is used to accommodate at least a portion of the frame 20. For example, the avoidance groove 10a is used to accommodate a pair of longitudinal beams of the frame 20 (such as the first longitudinal beam 21 and the second longitudinal beam 22), that is, to avoid a pair of longitudinal beams so that the longitudinal beams can pass through the bracket 10 in the longitudinal direction y of the frame.

[0335] In other embodiments, please refer to FIG15 , which is a front view of the bracket 10 and the frame 20 in other embodiments of the present application. In FIG15 , the avoidance groove 10a can be used to accommodate a longitudinal beam of the frame 20 (such as the first longitudinal beam 21 or the second longitudinal beam 22), that is, to avoid one longitudinal beam, so that the longitudinal beam can pass through the bracket 10 in the longitudinal direction y of the frame.

[0336] “At least a portion of the vehicle frame 20 is accommodated in the avoidance groove 10 a ” can also be understood as that, in the height direction, a portion of the bracket 10 can utilize the space where the vehicle frame 20 is located.

[0337] In the above solution, by providing the avoidance groove 10a on the bracket 10, at least part of the frame 20 can be avoided, so as to reasonably utilize the space where at least part of the frame 20 is located, and reduce the impact of the installation of the bracket 10 on the ground clearance of the vehicle body 1000.

[0338] According to some embodiments of the present application, the vehicle frame 20 is connected to the groove bottom wall and / or groove side wall of the avoidance groove 10a.

[0339] In some embodiments, the frame 20 can be connected to the bottom wall of the avoidance trough 10a. The frame 20 can be connected to the bottom wall of the avoidance trough 10a by welding, riveting, screwing, or other connection methods. In some embodiments, the frame 20 can be connected to the side walls of the avoidance trough 10a. The frame 20 can be connected to the side walls and bottom wall of the avoidance trough 10a by welding, riveting, screwing, or other connection methods. In some embodiments, the frame 20 can be connected to the side walls and bottom wall of the avoidance trough 10a.

[0340] In the above scheme, since at least part of the frame 20 is accommodated in the avoidance groove 10a, the frame 20 can be connected to the groove bottom wall and / or groove side wall of the avoidance groove 10a, and the avoidance groove 10a can be reasonably utilized, so that the avoidance groove 10a can not only avoid the bracket 10, but also realize the connection between the bracket 10 and the frame 20, simplifying the connection structure between the bracket 10 and the frame 20, reducing the installation difficulty and reducing the installation cost.

[0341] According to some embodiments of the present application, referring to FIG. 2 , the first connector 200 is installed on the bracket assembly 100 .

[0342] In some embodiments, the first connector 200 may be mounted to the bracket assembly 100 by bonding, welding, riveting, or screwing. Alternatively, the first connector 200 may be mounted to the bracket assembly 100 by a binding member.

[0343] In the above solution, by installing the first connector 200 on the bracket assembly 100, when the battery 2000 is installed on the bracket assembly 100, the first connector 200 and the second connector can be docked simultaneously, thereby improving the battery replacement efficiency.

[0344] In some other embodiments, the first connector 200 can be installed at other locations of the vehicle body 1000 .

[0345] According to some embodiments of the present application, please refer to FIG16 , which is a schematic diagram of a vehicle body 1000 in some embodiments of the present application. The vehicle body 1000 includes a cargo box 400 , and the bracket assembly 100 is located below the cargo box 400 .

[0346] The vehicle body 1000 is applied to a truck, which may include a cargo box 400 for carrying goods. The bracket assembly 100 is disposed below the cargo box 400 and can bear the load of the cargo box 400 and the goods in the cargo box 400.

[0347] “The bracket assembly 100 is located below the cargo compartment 400 ” can also be understood as the battery 2000 is located below the cargo compartment 400 .

[0348] In the above solution, the vehicle body 1000 can be a freight vehicle body 1000, which can include a cargo box for carrying cargo. For example, the vehicle body 1000 can be the vehicle body 1000 of a heavy truck. By arranging the bracket assembly 100 below the cargo box, the space below the cargo box can be rationally utilized. Compared with the current backpack-style battery replacement of heavy trucks (where the battery 2000 is installed on the back of the heavy truck's cab), the position layout of the battery 2000 in the vehicle body 1000 is changed, which can effectively save space in the longitudinal direction of the vehicle 10000, reduce the space occupied by the cargo box, and increase the cargo capacity of the vehicle 10000.

[0349] According to some embodiments of the present application, the present application further provides a vehicle 10000, comprising the vehicle body 1000 described above and at least one battery 2000. Each battery 2000 is detachably connected to a set of first mounting portions 300, and the second connector of each battery 2000 is connected to one of the first connectors 200.

[0350] In the above scheme, a vehicle 10000 is provided, in which the vehicle body 1000 can replace batteries on demand, that is, according to its own endurance requirements, the number of replacement batteries 2000 is adjusted to achieve the purpose of reducing battery replacement costs.

[0351] According to some embodiments of the present application, please refer to Figure 3 and Figure 17. Figure 17 is a schematic diagram of a battery 2000 in some embodiments of the present application. The battery 2000 has an escape space 2001 for escaping the bracket assembly 100.

[0352] The avoidance space 2001 may be a recessed portion of the battery 2000 for avoiding the bracket assembly 100. Referring to Figures 3 and 17, in the height direction, the upper surface of the battery 2000 may be a concave-convex surface, and the recessed portion forms the avoidance space 2001.

[0353] In some embodiments, the bracket assembly 100 includes a frame 20 , and the avoidance space 2001 can avoid a pair of longitudinal beams of the frame 20 , that is, the protruding portion of the upper surface of the battery 2000 can utilize the space where the frame 20 is located.

[0354] In the above solution, by providing the avoidance space 2001 on the battery 2000 , the space where the bracket assembly 100 is located can be reasonably utilized, the capacity of the battery 2000 can be increased, and a longer driving range can be provided for the vehicle 10000 .

[0355] According to some embodiments of the present application, referring to Fig. 3 , the bracket assembly 100 includes a vehicle frame 20. Along a transverse direction x of the vehicle frame, a projection of the battery 2000 at least partially overlaps with a projection of the vehicle frame 20.

[0356] The transverse direction x of the frame can be the arrangement direction of the pair of longitudinal beams in the frame 20, or it can be the width direction of the vehicle 10000. "Along the transverse direction x of the frame, the projection of the battery 2000 at least partially overlaps with the projection of the frame 20" can be understood as meaning that, in the height direction, the battery 2000 has an upwardly protruding portion, and the projection of this protruding portion in the transverse direction x of the frame can fall onto the frame 20. "Along the transverse direction x of the frame, the projection of the battery 2000 at least partially overlaps with the projection of the frame 20" can also be understood as meaning that, in the height direction, the battery 2000 can utilize the space within the frame 20.

[0357] In the above solution, the transverse direction x of the vehicle frame can be perpendicular to the direction of travel of the vehicle 10000 and can also be understood as the width direction of the vehicle 10000. By arranging the battery 2000 so that its projection at least partially overlaps with the projection of the frame 20 along the transverse direction x of the vehicle frame, the battery 2000 can effectively utilize the height space of the vehicle body 1000, thereby increasing the capacity of the battery 2000 and providing a longer driving range for the vehicle 10000.

[0358] According to some embodiments of the present application, the bracket assembly 100 includes a vehicle frame 20 . The battery 2000 includes a housing and a plurality of battery cells disposed in the housing. Along the transverse direction x of the vehicle frame, the projections of at least some of the battery cells overlap with the projection of the vehicle frame 20 .

[0359] The battery 2000 may include a housing and battery cells. The volume of the battery cells affects the capacity of the battery 2000.

[0360] “Along the transverse direction x of the frame, the projection of at least a portion of the battery cells overlaps with the projection of the frame 20 ” can be understood as that in the height direction, at least a portion of the battery cells can utilize the space where the frame 20 is located.

[0361] In the above solution, the transverse direction x of the vehicle frame can be perpendicular to the direction of travel of the vehicle 10000 and can also be understood as the width direction of the vehicle 10000. By arranging at least a portion of the battery cells in the battery 2000 along the transverse direction x of the vehicle frame so that their projections at least partially overlap with the projections of the vehicle frame 20, the at least portion of the battery cells can effectively utilize the height space of the vehicle body 1000, thereby increasing the capacity of the battery 2000 and providing a longer driving range for the vehicle 10000.

[0362] According to some embodiments of the present application, the lowest point of the battery 2000 is lower than the lowest point of the bracket 10 .

[0363] In some embodiments, the lowest point of the battery 2000 can be understood as the portion of the battery 2000 closest to the ground. The lowest point of the bracket 10 can be understood as the portion of the bracket 10 closest to the ground.

[0364] In the above solution, by setting the lowest point of the battery 2000 to be lower than the lowest point of the bracket 10, the battery 2000 can reasonably utilize the height space of the vehicle body 1000, increase the capacity of the battery 2000, and provide a longer battery life for the vehicle 10000.

[0365] According to some embodiments of the present application, the vehicle 10000 is a heavy truck.

[0366] In some embodiments, the heavy-duty truck can be a heavy-duty truck, which requires different battery 2000 capacities when transporting different goods or on different transportation routes (for example, under short-distance endurance requirements, one battery 2000 is required, under medium-distance endurance requirements, two batteries 2000 are required, and under long-distance endurance requirements, three batteries 2000 are required). Through the vehicle body 1000 provided above, on-demand battery replacement can be achieved (for example, for short-distance endurance requirements, only one battery 2000 is replaced, that is, one battery 2000 is carried; for medium-distance endurance requirements, only two batteries 2000 are replaced, that is, two batteries 2000 are carried; for long-distance endurance requirements, three batteries 2000 are replaced, that is, three batteries 2000 are carried), thereby saving the cost of additional batteries 2000 and effectively reducing the cost of battery replacement.

[0367] According to some embodiments of the present application, a vehicle body 1000 is provided, see Figures 1-16.

[0368] The vehicle body 1000 can be applied to heavy trucks, that is, heavy trucks. When heavy trucks transport different goods or have different transportation routes, the required capacity of the battery 2000 is different. For example, under short-distance endurance requirements, a 200-degree battery 2000 (for example, one battery 2000) is required, under medium-distance endurance requirements, a 400-degree battery 2000 (for example, two batteries 2000) is required, and under long-distance endurance requirements, a 600-degree battery 2000 (for example, three batteries 2000) is required. In order to save the cost of battery replacement, the vehicle body 1000 may include a bracket assembly 100 and a plurality of first connectors 200. The first connector 200 may be a structure connected to the second connector of the battery 2000, and the first connector 200 may be a high- and low-voltage connector or / and a liquid-cooled connector.

[0369] The bracket assembly 100 includes a frame 20 and a bracket 10. The frame 20 can be a beam of a heavy truck.

Each set of first mounting portions 300 is used to detachably connect to a battery 2000. The number of first connectors 200 is equal to the number of sets of first mounting portions 300. Each first connector 200 is used to connect to the second connector of a battery 2000. In some embodiments, the bracket 10 is provided with three sets of first mounting portions 300. The number of first connectors 200 can be three.

[0370] Referring to Figure 2 , the bracket 10 has three accommodating spaces 100a arranged along a first direction. Each accommodating space 100a is configured to accommodate a battery 2000, and each accommodating space 100a is provided with a corresponding set of first mounting portions 300. Each accommodating space 100a is divided by the first and second longitudinal beams 21, 22 into a first subspace 100b, a second subspace 100c, and a third subspace 100d. The first subspace 100b is located between the first and second longitudinal beams 21, 22; the second subspace 100c is located on the side of the first longitudinal beam 21 facing away from the second longitudinal beam 22; and the third subspace 100d is located on the side of the second longitudinal beam 22 facing away from the first longitudinal beam 21. A single battery 2000 can be accommodated in each of the first, second, and third subspaces 100b, 100c, and 100d, ensuring uniform force distribution on the bracket 10.

[0371] Referring to Figures 7 and 8 , the bracket 10 includes a plurality of mounting units 11 spaced apart along a first direction, with a receiving space 100a formed between adjacent mounting units 11.

A portion of the mounting beam 12 is positioned between the first longitudinal beam 21 and the second longitudinal beam 22, with portions of the mounting beam 12 extending beyond the first longitudinal beam 21 and the second longitudinal beam 22. Multiple first mounting portions 300 are provided on the mounting beam 12. Two adjacent mounting units 11 can carry a single battery 2000. In some embodiments, a set of first mounting portions 300 can be provided on the mounting beams 12 of two adjacent mounting units 11. Each mounting unit 11 includes two connecting portions 13 spaced apart along the transverse direction x of the vehicle frame. A pair of longitudinal beams are positioned between the two connecting portions 13, with each connecting portion 13 connected to the outer side of a corresponding longitudinal beam. Each mounting unit 11 includes two ribs 14 corresponding to the connecting portion 13 . The ribs 14 are disposed between the corresponding connecting portion 13 and the mounting beam 12 .

[0372] In the above scheme, by setting multiple first connectors 200 and multiple groups of first mounting parts 300 on the bracket 10, the number of batteries 2000 that need to be replaced can be adjusted based on the endurance requirements (that is, replacement on demand). For example, for short-distance endurance requirements, only one battery 2000 is replaced, that is, one battery 2000 is carried; for medium-distance endurance requirements, only two batteries 2000 are replaced, that is, two batteries 2000 are carried; for long-distance endurance requirements, three batteries 2000 are replaced, that is, three batteries 2000 are carried, thereby saving the cost of additional batteries 2000 and effectively reducing the cost of battery replacement.
