Technical Field

[0001] The present application relates to the technical field of new energy vehicles, and in particular to a vehicle body and a vehicle. Background Art

[0002] New energy vehicles have become an important part of the sustainable development of the vehicle industry due to their energy-saving and environmental protection 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.

[0003] For new energy vehicles, how to reduce the cost of battery replacement is a technical problem that needs to be solved urgently. Summary of the invention

[0004] The present application provides a vehicle body and a vehicle, which can effectively reduce the cost of battery replacement.

[0005] This application is achieved through the following technical solutions:

[0006] In a first aspect, the present application provides a vehicle body, the vehicle body comprising a bracket assembly and a plurality of first connectors, the bracket assembly being provided with a plurality of groups of first mounting parts, each group of first mounting parts being used for detachably connecting a battery, the number of first connectors being equal to the number of groups of first mounting parts, and each first connector being used for connecting to a second connector of a battery.

[0007] 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 first mounting parts on the bracket assembly, the number of batteries to be replaced can be adjusted based on the endurance requirements (that is, battery replacement on demand, for example, when the required endurance is shorter, a smaller number of batteries can be installed on a corresponding number of first mounting parts in a plurality of first mounting parts, and the second connector of each battery is connected to the corresponding first connector; when the required endurance is longer, a larger number of batteries can be installed on a corresponding number of first mounting parts in a plurality 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.

[0008] According to some embodiments of the present application, the bracket assembly includes a frame.

[0009] In the above scheme, the frame can be the main support of the vehicle body and can bear various loads inside and outside the vehicle body. The frame can be provided with a first mounting portion, which can stably carry the battery, improve the connection stability between the battery and the vehicle body, and reduce the risk of battery falling off; on the other hand, the frame is at the bottom of the vehicle body, so 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 cab of the heavy truck), the position layout of the battery of the vehicle body is changed, which can effectively save space in the length direction of the vehicle, so as to increase the cargo capacity of the vehicle.

[0010] According to some embodiments of the present application, the bracket assembly also includes a bracket, the bracket is fixedly connected to the frame, and the bracket is provided with a first mounting portion.

[0011] In the above scheme, by fixing 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.

[0013] In the above scheme, 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 surface 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 caused by the installation of the bracket to the inside of the vehicle body can be reduced; on the other hand, for the current vehicle body installation of the bracket, the difficulty of strengthening the bracket is low and the feasibility is strong; 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 cab of the heavy truck), the position layout of the battery of the vehicle body is changed, which can effectively save space in the length direction of the vehicle, so as to increase the cargo capacity of the vehicle.

[0014] According to some embodiments of the present application, along the direction from the first longitudinal beam to the second longitudinal beam, the bracket exceeds the second longitudinal beam.

[0015] 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 meet the different endurance requirements of different vehicles or different endurance requirements of vehicles.

[0018] According to some embodiments of the present application, along the direction from the second longitudinal beam to the first longitudinal beam, the bracket exceeds the first longitudinal beam.

[0019] 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 meet the different endurance requirements of different vehicles or different endurance requirements of vehicles.

[0020] According to some embodiments of the present application, at least one first mounting portion is provided on a portion of the bracket that extends beyond the first longitudinal beam.

[0023] In the above scheme, the center of gravity of the vehicle body can be located between the first longitudinal beam and the second longitudinal beam. To this end, on the one hand, by setting at least a part of the bracket between the first longitudinal beam and the second longitudinal beam, the influence of the bracket on the center of gravity of the vehicle body can be reduced, and the driving stability of the vehicle body can be improved; on the other hand, when the battery is installed on the bracket, part of the battery or a portion of the battery can be located between the first longitudinal beam and the second longitudinal beam, which can reduce the influence of the installation of the battery on the center of gravity of the vehicle body and improve the driving stability of the vehicle body.

[0024] 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.

[0025] In the above scheme, 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.

[0026] According to some embodiments of the present application, a second mounting portion is provided on the frame, and the second mounting portion is used to detachably connect the battery.

[0027] In the above scheme, by providing the second mounting part on the vehicle frame and cooperating with the first mounting part to be detachably connected to the battery, the connection stability between the battery and the vehicle body can be improved, and the driving reliability of the vehicle body can be improved.

[0028] 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 disposed on the first longitudinal beam and / or the second longitudinal beam.

[0029] In the above solution, the vehicle frame may include a first longitudinal beam and a second longitudinal beam in the beam, for example, the vehicle frame may include a first longitudinal beam and a second longitudinal beam in the beam of a large vehicle (such as a heavy truck). By arranging the second mounting part on the first longitudinal beam and / or the second longitudinal beam, it can effectively cooperate with the first mounting part, so that the battery is effectively connected to the vehicle body, reducing the risk of battery falling off and improving the driving reliability of the vehicle body.

[0030] 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 disposed on the cross beam.

[0031] In the above scheme, the vehicle frame may include the first longitudinal beam, the second longitudinal beam and the cross beam in the beam. For example, the vehicle frame may include the first longitudinal beam, the second longitudinal beam and the cross beam in the beam of a large vehicle (such as a heavy truck). By arranging the second mounting part on the cross beam, on the one hand, it can effectively cooperate with the first mounting part, so that the battery is effectively connected to the vehicle body, reducing the risk of battery falling off and improving the driving reliability of the vehicle body; on the other hand, since the cross beam is located between the first longitudinal beam and the second longitudinal beam, arranging the second mounting part on the cross beam can reasonably utilize the space between the first longitudinal beam and the second longitudinal beam, reduce the interference of the second mounting part on the bracket, and improve the battery replacement efficiency of the vehicle body.

[0032] 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.

[0033] In the above scheme, by arranging 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.

[0034] According to some embodiments of the present application, the accommodation space has an opening that opens downward, and the opening is used for the battery to enter or leave the accommodation space.

[0035] In the above scheme, by providing an opening that opens downward, it is convenient for the battery to enter or leave the storage space from the bottom of the vehicle body. Compared with the current backpack-type battery replacement scheme for heavy trucks, on the one hand, it can save space on 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.

[0036] According to some embodiments of the present application, the first direction is parallel to the longitudinal direction of the frame.

[0037] In the above solution, the longitudinal direction of the frame can be parallel to the driving direction of the vehicle body, and the longitudinal direction of the frame can be the extension direction of the longitudinal beam in the frame. By setting the first direction to be parallel to the longitudinal direction of the frame, that is, multiple batteries are arranged along the longitudinal direction of the frame, the center of gravity of the battery can be close to the center of the frame in the lateral direction, reducing the influence of the installation of the battery on the center of gravity of the vehicle body, so that the vehicle body has higher driving reliability.

[0038] 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 a side of the first longitudinal beam away from the second longitudinal beam, and the third subspace is located on a side of the second longitudinal beam away from the first longitudinal beam.

[0039] 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). Based on the first longitudinal beam and the second longitudinal beam, the accommodation space is divided into a first subspace, a second subspace and a third subspace, and the weight of the battery is distributed based on the position of the first longitudinal beam and the second longitudinal beam, which can reduce the influence of the installation of the battery on the center of gravity of the vehicle body, so that the vehicle body has higher driving reliability.

[0040] 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.

[0041] 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.

[0042] According to some embodiments of the present application, at least two first mounting parts are arranged in the first subspace, at least two first mounting parts are arranged in the second subspace, and at least two first mounting parts are arranged in the third subspace.

[0043] In the above scheme, by distributing at least two first mounting parts 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, the battery can be connected evenly with force, so that the battery is stably placed in the accommodating space, reducing the risk of the battery falling off, and making the vehicle body have higher driving reliability.

[0044] According to some embodiments of the present application, at least two first mounting portions in the first subspace are respectively arranged on opposite sides of the first subspace along the longitudinal direction of the frame. And / or, at least two first mounting portions in the second subspace are respectively arranged on opposite sides of the second subspace along the longitudinal direction of the frame. And / or, at least two first mounting portions in the third subspace are respectively arranged on opposite sides of the third subspace along the longitudinal direction of the frame.

[0045] 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 connected and constrained 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 connected and constrained 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 connected and constrained 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.

[0046] According to some embodiments of the present application, the first direction is parallel to the transverse direction of the frame.

[0047] In the above scheme, the transverse direction of the frame can be perpendicular to the driving direction of the vehicle body, the transverse direction of the frame can be the arrangement direction of a 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 to be parallel to the transverse direction of the frame, that is, multiple batteries are arranged along the transverse direction of the frame, the battery can be replaced along the width direction of the vehicle body, which can effectively reduce the moving path of the battery and improve the battery replacement efficiency compared to replacing the battery along the length direction of the vehicle body.

[0048] 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 a side of the first longitudinal beam away from the second longitudinal beam, and at least one accommodating space is located on a side of the second longitudinal beam away from the first longitudinal beam.

[0049] 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 providing a storage space on the side of the first longitudinal beam away from the second longitudinal beam and providing a storage space on the side of the second longitudinal beam away from the first longitudinal beam, that is, arranging batteries on both sides of the vehicle frame, 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.

[0050] 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.

[0051] 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 position of the vehicle body can be reduced, so that the vehicle body has higher driving reliability.

[0052] 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.

[0053] 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.

[0054] 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.

[0055] In the above scheme, 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.

[0056] According to some embodiments of the present application, the accommodating space has a first end and a second end opposite to each other along a first direction, and the first mounting portion arranged at the first end is staggered with the first mounting portion arranged at the second end.

[0057] In the above scheme, by staggering the first mounting parts located 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 wrong 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 wrong installation of the bracket.

[0058] 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.

[0059] In the above scheme, 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 and batteries are connected to each other. Two adjacent accommodating spaces are close to each other in the first direction. For this reason, by staggering the first mounting parts of the two adjacent accommodating spaces at one end close to each other, the risk of interference between the two adjacent battery replacement execution ends can be reduced, so that multiple battery replacement execution ends can work at the same time, thereby improving the battery replacement efficiency.

[0060] 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.

[0061] In the above scheme, the size of the accommodation space along the first direction is smaller than the size along the second direction, which can be understood as the size of the battery monomer accommodated in the accommodation space along the first direction is smaller than the size along the second direction, that is, the size of the battery in the second direction can be the length of the battery. For this reason, when the first mounting portion is arranged at at least one end of the accommodation space along the first direction, it can be understood that the first mounting portion corresponds to the two sides of the shorter dimension of the battery, which can reduce the risk of the middle part of the battery collapsing downward due to gravity, and improve the connection stability between the battery and the bracket.

[0062] 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 in 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.

[0063] In the above solution, the vehicle frame may include a pair of longitudinal beams in the beam, for example, the vehicle frame may include a pair of longitudinal beams in the beam of a large vehicle (such as a heavy truck). By providing a connecting portion, the mounting beam can be effectively connected to the longitudinal beam, so that the mounting beam can effectively carry the battery through the first mounting portion, reducing the risk of battery falling off and improving the driving reliability of the vehicle body.

[0064] According to some embodiments of the present application, the connecting portion extends along the direction of gravity.

[0065] In the above scheme, by setting the connecting part to extend in 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.

[0066] 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 part and the mounting beam.

[0067] In the above scheme, by arranging ribs on the outer side 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 falling off and improving the driving reliability of the vehicle body.

[0068] According to some embodiments of the present application, the connecting portion includes a first sub-connecting portion and a second sub-connecting portion, the first sub-connecting portion and the second sub-connecting portion respectively extend from the edge of the rib in opposite directions, and the first sub-connecting portion and the second sub-connecting portion are both connected to the outer side surface of the longitudinal beam.

[0069] 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.

[0071] In the above scheme, on the one hand, by setting up multiple mounting units to carry multiple batteries, the purpose of battery replacement on demand can be achieved, and the cost of battery replacement can be reduced. On the other hand, by setting a connecting beam to connect two adjacent mounting units, the structural stability between the two adjacent mounting units can be effectively improved, the carrying capacity of the battery can be improved, the risk of battery falling off can be reduced, and the driving reliability of the vehicle body can be improved.

[0072] According to some embodiments of the present application, each mounting unit includes two connecting parts, the two connecting parts are arranged at intervals along the lateral 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.

[0073] In the above scheme, by setting 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.

[0075] In the above scheme, by arranging multiple mounting units at longitudinal intervals on 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 without interfering with each other, thereby improving the battery replacement efficiency of the vehicle body.

[0076] 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.

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, a bracket can be stably located on the outer side of one of the longitudinal beams in the frame. On the other hand, by arranging brackets on both sides of the frame, more batteries can be carried, the upper limit of the number of battery replacement batteries can be increased, and the vehicle's endurance can be improved.

[0078] According to some embodiments of the present application, the bracket includes a plurality of mounting units, and the plurality of mounting units are spaced apart along the longitudinal direction of the frame, and a space for accommodating a battery is formed between two adjacent mounting units.

[0079] In the above scheme, in the longitudinal direction of the frame, the bracket is provided with multiple mounting units to form 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, the multiple batteries can be arranged in the transverse direction of the frame, and the spaces formed by the multiple mounting units in one frame can jointly 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 carried by two frames.

[0080] According to some embodiments of the present application, the frame further comprises a crossbeam connected between a pair of longitudinal beams. The crossbeam is provided with a second mounting portion, and the second mounting portion is detachably connected to the battery.

[0081] In the above scheme, by providing a second mounting portion on the crossbeam, a mounting point is provided between the battery and the crossbeam, thereby improving the connection stability between the battery and the vehicle body and reducing the risk of the battery falling off. In some embodiments, when the battery is arranged along the longitudinal direction of the frame, multiple batteries can be arranged in the transverse direction of the frame, and by providing a second mounting portion on the crossbeam, at least one column of batteries can be carried at the corresponding position of the crossbeam.

[0100] According to some embodiments of the present application, the bracket assembly includes a frame. Along the lateral direction of the frame, a projection of the battery at least partially overlaps with a projection of the frame.

[0101] In the above solution, the lateral direction of the frame can be perpendicular to the driving direction of the vehicle, and can also be understood as the width direction of the vehicle. Along the lateral direction of the frame, by arranging the battery so that the projection overlaps at least partially with the projection of the frame, 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.

[0102] According to some embodiments of the present application, the bracket assembly includes a vehicle frame. The battery includes a box body and a plurality of battery cells disposed in the box body, and along the lateral direction of the vehicle frame, the projection of at least a portion of the battery cells overlaps with the projection of the vehicle frame.

[0103] In the above solution, the lateral direction of the frame can be perpendicular to the driving direction of the vehicle, and can also be understood as the width direction of the vehicle. Along the lateral direction of the frame, by arranging at least a portion of the battery cells in the battery so that the projection at least partially overlaps with the projection of the frame, the at least a portion of the battery cells can reasonably utilize the height space of the vehicle body, thereby increasing the battery capacity and providing the vehicle with a longer driving range.

[0104] According to some embodiments of the present application, the lowest point of the battery is lower than the lowest point of the bracket.

[0105] In the above scheme, 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 battery life.

[0106] According to some embodiments of the present application, the vehicle is a heavy truck.

[0107] A heavy-duty truck may be a heavy-duty truck, which requires different battery capacities when transporting different goods or on different transport routes (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.

[0131] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work 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 meaning as those commonly understood by technicians in the technical field of this application; 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" in the specification and claims of this application and the above-mentioned drawings and any variations thereof are intended to cover non-exclusive inclusions. The terms "first", "second", etc. 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 and secondary relationship.

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

[0134] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", and "attached" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0135] The term "and / or" in this application is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this application generally indicates that the associated objects before and after are in an "or" relationship.

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

[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 accommodated in the case.

[0139] In some embodiments, the battery cell may be a secondary battery, which refers to a battery cell that can be used continuously by activating the active material by charging after the battery cell is discharged. The battery cell may be a lithium ion battery, a sodium ion battery, a sodium lithium ion battery, a lithium metal battery, a sodium metal battery, a lithium sulfur battery, a magnesium ion battery, a nickel hydrogen battery, a nickel cadmium battery, a lead storage battery, etc., and the embodiments of the present application are not limited thereto.

[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, and the capacity of the whole battery is fixed, that is, the cruising range of the 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 caused by the additional capacity, and then when replacing the battery, the cost of battery replacement is higher.

[0141] In view of this, in order to solve the problem of high battery replacement cost due to different battery life requirements, some embodiments of the present application provide a vehicle body, which includes a bracket assembly and a plurality of first connectors. By providing a plurality of first mounting parts on the bracket assembly, a corresponding number of batteries can be detachably connected. By providing a plurality of first connectors, a corresponding number of second connectors of batteries can be connected.

[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 embodiment of the present application can be used, but not limited to, in the vehicle body of a passenger vehicle, the vehicle body of a commercial cargo vehicle, and the body of a vehicle of other nature. The vehicle body disclosed in the embodiment of the present application can be used, but not limited to, in the vehicle body of a passenger vehicle, the vehicle body of a commercial cargo vehicle, and the body of a vehicle of other nature.

[0144] Please refer to Figure 1 , Figure 1A schematic diagram of the structure of a vehicle 10000 provided for some embodiments of the present application. The vehicle 10000 may be a new energy vehicle, and the new energy vehicle may be a pure electric vehicle, a hybrid vehicle with replaceable battery, or an extended-range vehicle with 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, for example, for the working power requirements during the startup, navigation, and operation of 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 of 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, see Figure 2 and Figure 3 , Figure 2 A top view of a partial structure of a vehicle body 1000 in some embodiments of the present application is shown. Figure 3 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 a plurality of groups of first mounting portions 300, each group of first mounting portions 300 is used to detachably connect a battery 2000, the number of first connectors 200 is equal to the number of groups of first mounting portions 300, and each first connector 200 is used to connect to a 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 head of the vehicle body 1000, the tail 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 with 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 with 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 connected 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 a high-low voltage connector for connecting to the battery 2000 or a liquid cooling connector for connecting to the battery 2000. In some embodiments, the high-low voltage connector may be electrically connected to the battery 2000 to implement input or output of the battery 2000, and to implement input or output of electrical signals. The liquid cooling connector may be used for input or output of the heat exchange medium of the battery 2000 to perform thermal management on 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 the short-distance battery life requirement is to be met, only one battery 2000 may be mounted, and the second connector of the battery 2000 is connected to one first connector 200. When the mid-distance battery life requirement is to be met, only two batteries 2000 may be mounted, and the second connectors of the two batteries 2000 are respectively connected to two first connectors 200. When the long-distance battery life requirement is to be met, three batteries 2000 may 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 required 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 required 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, thereby effectively reducing the cost of battery replacement.

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

[0155] In some embodiments, the vehicle frame 20 may be a frame structure straddling the front and rear axles of the vehicle body 1000, commonly known as a beam, and is the base of the vehicle body 1000. The functions of the vehicle frame 20 may include supporting and connecting various assemblies of the vehicle body 1000, keeping the various assemblies in relatively 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 stably carry the battery 2000 on the one hand, 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 this application, see Figure 2 and Figure 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 to be able to mount 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 fixing the bracket 10 to the frame 20, on the one hand, the impact 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 retrofitted into the frame 20 of the current vehicle body 1000, and the installation is easy and efficient, so that the current vehicle 10000 can be quickly equipped with the function of on-demand battery replacement.

[0162] According to some embodiments of this application, see Figure 4 , Figure 4 This 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 may be applied to a commercial truck (e.g., a heavy truck) or a passenger vehicle (e.g., a bus), and the frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22. The first longitudinal beam 21 and the second longitudinal beam 22 may be arranged relatively spaced apart, and the direction in which the first longitudinal beam 21 and the second longitudinal beam 22 are relatively spaced apart may be the width direction of the vehicle body 1000, and the extension direction of the first longitudinal beam 21 and the second longitudinal beam 22 may 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 that along the height direction (the direction perpendicular to the ground, generally the vehicle 10000 is running 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, any part of the bracket 10 does not exceed 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 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, any part of the bracket 10 does not exceed the second longitudinal beam 22.

[0166] In the above solution, the frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 in a beam. For example, the 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 this application, see Figure 3 and Figure 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 part of the bracket 10 is located outside the vehicle frame 20 .

[0170] In the above scheme, 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 the vehicle 10000 or different endurance requirements of the vehicle 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 this application, see Figure 3 At least one first mounting portion 300 is provided on a portion of the bracket 10 that exceeds the second longitudinal beam 22 .

[0173] “At least one first mounting portion 300 is provided at the portion of the bracket 10 that exceeds the second longitudinal beam 22” can be understood as at least one first mounting portion 300 in a group or each group of first mounting portions 300 is provided at the portion of the bracket 10 that exceeds the second longitudinal beam 22. In some embodiments, a plurality of first mounting portions 300 may be provided at the portion of the bracket 10 that exceeds the second longitudinal beam 22, and the plurality of first mounting portions 300 are first mounting portions 300 in a plurality of groups of first mounting portions 300. In some embodiments, a plurality of first mounting portions 300 may be provided at the portion of the bracket 10 that exceeds the second longitudinal beam 22, and the plurality of first mounting portions 300 may be first mounting portions 300 in a group of mounting portions. In some embodiments, a first mounting portion 300 may be provided at the portion of the bracket 10 that exceeds the second longitudinal beam 22, and the 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 group of first mounting portions 300 may be provided at the portion of the bracket 10 that exceeds the second longitudinal beam 22.

[0174] In the above scheme, by providing at least one first mounting portion 300 on the portion of the bracket 10 that exceeds the second longitudinal beam 22, the portion of the battery 2000 that exceeds 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 exceeds the first longitudinal beam 21 .

[0176] In some embodiments, the direction in which the second longitudinal beam 22 points to 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 located on the side of the first longitudinal beam 21 away from the second longitudinal beam 22 , or part of the bracket 10 is located outside the vehicle frame 20 .

[0178] In the above scheme, 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 the vehicle 10000 or different endurance requirements of the vehicle 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 this application, see Figure 3 At least one first mounting portion 300 is provided on a portion of the bracket 10 that exceeds the first longitudinal beam 21 .

[0181] “At least one first mounting portion 300 is provided at the portion of the bracket 10 that exceeds the first longitudinal beam 21” can be understood as at least one first mounting portion 300 in a group or each group of first mounting portions 300 is provided at the portion of the bracket 10 that exceeds the first longitudinal beam 21. In some embodiments, a plurality of first mounting portions 300 may be provided at the portion of the bracket 10 that exceeds the first longitudinal beam 21, and the plurality of first mounting portions 300 are first mounting portions 300 in a plurality of groups of first mounting portions 300. In some embodiments, a plurality of first mounting portions 300 may be provided at the portion of the bracket 10 that exceeds the first longitudinal beam 21, and the plurality of first mounting portions 300 may be first mounting portions 300 in a group of mounting portions. In some embodiments, a first mounting portion 300 may be provided at the portion of the bracket 10 that exceeds the first longitudinal beam 21, and the 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 group of first mounting portions 300 may be provided at the portion of the bracket 10 that exceeds the first longitudinal beam 21.

[0182] In the above scheme, by setting at least one first mounting portion 300 on the portion of the bracket 10 that exceeds the first longitudinal beam 21, the portion of the battery 2000 that exceeds 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 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 scheme, the center of gravity of the vehicle body 1000 can be located between the first longitudinal beam 21 and the second longitudinal beam 22. To this end, on the one hand, by setting at least a portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22, the influence of the bracket 10 on the center of gravity of the vehicle body 1000 can be reduced, and the driving stability of the vehicle body 1000 can be improved; on the other hand, when the battery 2000 is installed on the bracket 10, part of the battery 2000 or a portion of the battery 2000 can be located 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, and the driving stability of the vehicle body 1000 can be improved.

[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 the number of the brackets 10 is two, 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 this application, see Figure 2 At least one first mounting portion 300 is provided at 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 disposed in the portion of the bracket between the first longitudinal beam 21 and the second longitudinal beam 22 may be one, two, three or more.

[0189] “The portion of the bracket 10 between the first longitudinal beam 21 and the second longitudinal beam 22 is provided with at least one first mounting portion 300” can be understood as at least one first mounting portion 300 in a group or each group of first mounting portions 300 is provided in 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 can be provided with a plurality of first mounting portions 300, and the plurality of first mounting portions 300 are first mounting portions 300 in a plurality of 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 can be provided with a plurality of first mounting portions 300, and the plurality of first mounting portions 300 can be 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 can 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 group 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 scheme, by setting 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, see Figure 5 , Figure 5 Schematic diagram of the bracket assembly 100 in some 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 with the battery 2000. In some embodiments, the second mounting portion 301 includes but is not limited to mounting holes, mounting screws, and other structures capable of detachably connecting with the battery 2000. In some embodiments, the second mounting portion 301 may 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 the first longitudinal beam 21 and the second longitudinal beam 22.

[0199] In the above solution, the frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 in the beam, for example, the frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 in the beam of a large vehicle 10000 (such as a heavy truck). By arranging the second mounting portion 301 on the first longitudinal beam 21 and / or the second longitudinal beam 22, 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.

[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 beam 21 and the second longitudinal beam 22 are arranged at a relative interval, the cross beam 23 is located in the gap formed by the first longitudinal beam 21 and the second longitudinal beam 22, and the cross beam 23 connects the first longitudinal beam 21 and the second longitudinal beam 22. The cross beam 23 can improve the structural strength of the frame 20, so that the frame 20 can effectively bear various loads inside and outside the vehicle body 1000.

[0202] In the above scheme, the frame 20 may include the first longitudinal beam 21, the second longitudinal beam 22 and the cross beam 23 in the beam. For example, the frame 20 may include the first longitudinal beam 21, the second longitudinal beam 22 and the cross beam 23 in the beam of a large vehicle 10000 (such as a heavy truck). By setting the second mounting part 301 on the cross beam 23, on the one hand, it can effectively cooperate with the first mounting part 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, the second mounting part 301 is set on the cross beam 23, which can reasonably utilize the space between the first longitudinal beam 21 and the second longitudinal beam 22, reduce the interference of the second mounting part 301 on the bracket 10, and improve the battery replacement efficiency of the vehicle body 1000.

[0203] According to some embodiments of this application, see Figure 2 and Figure 3 The bracket assembly 100 has a plurality of accommodating spaces 100 a arranged along a first direction, each accommodating space 100 a is used to accommodate a battery 2000 , and each accommodating space 100 a is correspondingly provided with a set of first mounting portions 300 .

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

[0207] In the above scheme, by arranging a plurality of 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, see Figure 3The accommodation space 100 a has an opening that opens downward, and the opening is used for the battery 2000 to enter or leave the accommodation space 100 a.

[0209] “The accommodating space 100a has an opening that opens downward” can be understood as that the accommodating space 100a has an opening toward 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 leave 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 disposed 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 an opening that opens downward, it is convenient for the battery 2000 to enter or leave the accommodating space 100a from the bottom of the vehicle body 1000. Compared with the current backpack-type battery replacement scheme for 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, 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.

[0213] According to some embodiments of this application, see Figure 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 driving direction of the vehicle 10000 .

[0216] In some embodiments, see Figure 3 The battery 2000 may be in the shape of a long strip. When the first direction is parallel to the longitudinal direction y of the frame, the length direction of the battery 2000 may be perpendicular to the first direction, that is, the length direction of the battery 2000 may be parallel to the transverse direction x of the frame. The transverse direction x of the frame may be the arrangement direction of a pair of longitudinal beams in the frame 20, and the transverse direction x of the frame may also be the width direction of the vehicle 10000. Figure 3 , three batteries 2000 are arranged along the longitudinal direction y of the frame.

[0217] In the above solution, the longitudinal direction y of the frame can be parallel to the driving direction of the vehicle body 1000, and the longitudinal direction y of the frame can be the extension direction of the longitudinal beam in the frame 20. By setting the first direction to be parallel to the longitudinal direction y of the frame, that is, the plurality of batteries 2000 are arranged along the longitudinal direction y of the frame, the center of gravity of the battery 2000 can be close to the center of the frame in the transverse direction x, reducing the influence of the installation of the battery 2000 on the center of gravity of the vehicle body 1000, so that the vehicle body 1000 has higher driving reliability.

[0218] According to some embodiments of this application, see Figure 2 The frame 20 includes a first longitudinal beam 21 and a second longitudinal beam 22. 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 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 arranged relatively spaced apart, and the direction in which the first longitudinal beam 21 and the second longitudinal beam 22 are relatively spaced apart can be the width direction of the vehicle body 1000 or the transverse direction x of the frame, and the extension direction of the first longitudinal beam 21 and the second longitudinal beam 22 can be 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, and the three subspaces include 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 solution, the frame 20 may include the first longitudinal beam 21 and the second longitudinal beam 22 in the beam, for example, the frame 20 may include the first longitudinal beam 21 and the second longitudinal beam 22 in the beam of a large vehicle 10000 (such as a heavy truck). By dividing the accommodation space 100a into the first subspace 100b, the second subspace 100c and the third subspace 100d based on the first longitudinal beam 21 and the second longitudinal beam 22, the weight of the battery 2000 is evenly distributed based on the positions of the first longitudinal beam 21 and the second longitudinal beam 22, which can reduce the influence of the center of gravity position of the vehicle body 1000 caused by installing the battery 2000, so that the vehicle body 1000 has higher driving reliability.

[0224] According to some embodiments of this application, see Figure 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 group of first mounting parts 300. “The first subspace 100b is correspondingly provided with at least one first mounting part 300, the second subspace 100c is correspondingly provided with at least one first mounting part 300, and the third subspace 100d is correspondingly provided with at least one first mounting part 300” can be understood as that the parts of the battery 2000 in the first subspace 100b, the second subspace 100c and the third subspace 100d can be connected to the corresponding first mounting parts 300 respectively.

[0226] In some embodiments, the first subspace 100b is provided with one, two, three or more first mounting parts 300. The second subspace 100c is provided with one, two, three or more first mounting parts 300. The third subspace 100d is provided with one, two, three or more first mounting parts 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 this application, see Figure 3 At least two first mounting parts 300 are arranged in the first subspace 100b, at least two first mounting parts 300 are arranged in the second subspace 100c, and at least two first mounting parts 300 are arranged in the third subspace 100d.

[0229] “At least two first mounting parts 300 are arranged in the first subspace 100b, at least two first mounting parts 300 are arranged in the second subspace 100c, and at least two first mounting parts 300 are arranged in the third subspace 100d” can be understood as, in the accommodating space 100a, each subspace is arranged 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, see Figure 3 , four first mounting parts 300 are provided in the first subspace 100b, and the four first mounting parts 300 can be correspondingly provided on both sides of the width direction of the battery 2000 to connect the part of the battery 2000 in the first subspace 100b. Four first mounting parts 300 are provided in the second subspace 100c, and the four first mounting parts 300 can be correspondingly provided on both sides of the width direction of the battery 2000 to connect the part of the battery 2000 in the second subspace 100c. Four first mounting parts 300 are provided in the third subspace 100d, and the four first mounting parts 300 can be correspondingly provided on both sides of the width direction of the battery 2000 to connect the part of the battery 2000 in 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 evenly with force, so that the battery 2000 is stably in the accommodating space 100a, reducing the risk of the battery 2000 falling off, so that the vehicle body 1000 has higher driving reliability.

[0232] According to some embodiments of this application, see Figure 2 , at least two first mounting parts 300 in the first subspace 100b are respectively arranged at opposite sides of the first subspace 100b along the longitudinal direction y of the frame. And / or, at least two first mounting parts 300 in the second subspace 100c are respectively arranged at opposite sides of the second subspace 100c along the longitudinal direction y of the frame. And / or, at least two first mounting parts 300 in the third subspace 100d are respectively arranged at opposite sides of the third subspace 100d along the longitudinal direction y of the 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 subspace 100c are arranged on both sides of the second subspace 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 scheme, by arranging at least two first mounting parts 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 parts 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 connected and constrained on both sides of the longitudinal direction of the frame 20. 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 parts 300 in the third subspace 100d on opposite sides of the third subspace 100d along 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.

[0237] In some other embodiments, at least two first mounting parts 300 in the first subspace 100b may be disposed on the same side of the first subspace 100b. In some embodiments, at least two first mounting parts 300 in the second subspace 100c may be disposed on the same side of the second subspace 100c. In some embodiments, at least two first mounting parts 300 in the third subspace 100d may be disposed on the same side of the third subspace 100d.

[0238] According to other embodiments of the present application, see Figure 6 , Figure 6 Schematic diagram of the support assembly 100 and the battery 2000 in some other embodiments of the present application. The first direction is parallel to the horizontal direction x of the frame.

[0239] 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 .

[0240] The transverse direction x of the frame can be the arrangement direction of a pair of longitudinal beams in the frame 20, and the transverse direction x of the frame can also be the width direction of the vehicle 10000. Figure 6 The battery 2000 may be in the shape of a long strip. When the first direction is parallel to the horizontal direction x of the frame, the length direction of the battery 2000 may be perpendicular to the first direction, that is, the length direction of the battery 2000 may be parallel to the longitudinal direction y of the frame. 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 driving direction of the vehicle 10000. Figure 6 , three batteries 2000 are arranged along the transverse direction x of the frame.

[0241] In the above solution, the transverse direction x of the frame can be perpendicular to the driving direction of the vehicle body 1000, the transverse direction x of the frame can be the arrangement direction of a 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 to be parallel to the transverse direction x of the frame, that is, the plurality of batteries 2000 are arranged along the transverse direction x of the frame, the battery can be replaced along the width direction of the vehicle body 1000, which can effectively reduce the moving path of the battery 2000 and improve the battery replacement efficiency compared to replacing the battery along the length direction of the vehicle body 1000.

[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 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 arranged relatively spaced apart, and the direction in which the first longitudinal beam 21 and the second longitudinal beam 22 are relatively spaced apart can be the width direction of the vehicle body 1000 or the transverse direction x of the frame, and the extension direction of the first longitudinal beam 21 and the second longitudinal beam 22 can be the length direction of the vehicle body 1000.

[0244] In some embodiments, the number of the accommodation spaces 100a may be two or more. Some of the accommodation spaces 100a may be arranged on the side of the first longitudinal beam 21 away from the second longitudinal beam 22 , and the other part of the accommodation 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 solution, the frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 in the beam, for example, the frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22 in the 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 away from the second longitudinal beam 22, and providing a receiving space 100a on the side of the second longitudinal beam 22 away from the first longitudinal beam 21, that is, arranging the batteries 2000 on both sides of the frame 20, the influence of the installation of the batteries 2000 on the center of gravity of the vehicle body 1000 can be reduced, so that the vehicle body 1000 has higher driving reliability.

[0246] According to some embodiments of this application, see Figure 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 accommodation spaces 100a is at least three, that is, the bracket 10 can mount at least three batteries 2000. At least one accommodation 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 position of the vehicle body 1000 can be reduced, so that the vehicle body 1000 has higher driving reliability.

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

[0250] “The first mounting portion 300 is disposed 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 disposed at one end of the accommodating space 100a, or the first mounting portions 300 can be disposed 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 this application, see Figure 2 The first mounting portions 300 are disposed at opposite ends of the accommodating space 100a 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 the first mounting portions 300 provided at the opposite ends of the accommodation space 100a may be the same or different.

[0254] In the above scheme, by setting the first mounting part 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, see Figure 2 The accommodating space 100a has a first end and a second end opposite to each other along the first direction, and the first mounting portion 300 disposed at the first end and the first mounting portion 300 disposed at the second end are staggered.

[0256] The first end and the second end are two opposite locations 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 part 300 disposed at the first end and the first mounting part 300 disposed at the second end are staggered” can be understood as that along the first direction, the projection of the first mounting part 300 disposed at the first end and the projection of the first mounting part 300 disposed at the second end do not overlap each other. In other words, it can be understood that the first mounting part 300 disposed at the first end is translated to the second end along the first direction without interfering with the first mounting part 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 and reduces the risk of wrong installation of the battery 2000; on the other hand, it has a visual fool-proof effect on the installation of the bracket 10 and reduces the risk of wrong 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 parts 300 at the ends of two adjacent receiving spaces 100a close to each other are staggered” can be understood as the first mounting parts 300 corresponding to the parts of the two batteries 2000 close to each other in the two adjacent receiving spaces 100a are staggered. Figure 2 , the first mounting part 300 disposed at one end of one of the accommodating spaces 100a close to the other accommodating space 100a is translated along the first direction to the end of the other accommodating space 100a close to the one of the accommodating spaces 100a, and will not interfere with the first mounting part 300 originally disposed at one end of the other accommodating space 100a close to the one of the accommodating spaces 100a. That is, the first mounting parts 300 at the ends of the two adjacent accommodating spaces 100a close to each other are not only spaced apart from each other in the first direction, but also have a distance in the direction perpendicular to the first direction.

[0261] In the above scheme, 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. Two adjacent accommodating spaces 100a are close to each other in the first direction. For this reason, by staggering the first mounting parts 300 at one end 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, so that multiple battery replacement execution ends can work at the same time, thereby improving the battery replacement efficiency.

[0262] According to some embodiments of the present application, see Figure 2 and Figure 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 arrangement direction of the plurality of accommodation spaces 100a, and the second direction may be a direction perpendicular to the first direction and perpendicular to the gravity direction z. In some embodiments, when the first direction is the longitudinal direction y of the frame, the second direction may be the transverse direction x of the frame. When the first direction is the transverse 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 strip 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 size of the accommodating space 100a along the first direction is smaller than the size along the second direction, which can be understood as the size of the battery monomer that the accommodating space 100a is used to accommodate along the first direction is smaller than the size along the second direction, that is, the size of the battery 2000 in the second direction can be the length of the battery 2000. For this reason, 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 two sides of the shorter dimension of the battery 2000, which can reduce the risk of the middle part of the battery 2000 collapsing downward due to gravity, and improve the connection stability between the battery 2000 and the bracket 10.

[0266] According to some embodiments of this application, see Figure 7 and Figure 8 , Figure 7 This is a schematic diagram of a frame 20 and a bracket 10 in some embodiments of the present application. Figure 8 for Figure 7 Enlarged view of point A in the middle.

[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, and the mounting beam 12 extends along the transverse direction x of the vehicle frame. Along 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. 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 may be applied to a commercial truck (e.g., a heavy truck) or a passenger vehicle (e.g., a bus), and the frame 20 may include a pair of longitudinal beams (the longitudinal beams may be a first longitudinal beam 21 and a second longitudinal beam 22) arranged relatively spaced apart. The transverse direction x of the frame may be the arrangement direction of the pair of longitudinal beams. In some embodiments, the transverse direction x of the frame may be the width direction of the vehicle 10000. The longitudinal direction y of the frame may be the extension direction of the longitudinal beams. In some embodiments, the transverse direction x of the frame may be the length direction or the travel direction of the vehicle 10000.

[0269] The mounting unit 11 is a unit of the bracket 10 for mounting 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 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, which may be in the shape of a rod, see Figure 7 , the mounting beam 12 may extend along the transverse direction x of the frame. In some embodiments, the mounting beam 12 may be located outside the frame 20. In some embodiments, the mounting beam 12 may be located between a pair of longitudinal beams of the frame 20. In some embodiments, a portion of the mounting beam 12 may be located between a pair of longitudinal beams of the frame 20, and the portion of the mounting beam 12 may be 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 frame 20, and the portion of the mounting beam 12 may be on both sides of the frame 20 along the transverse direction x of the 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, screw connection or other connection methods. In some embodiments, the mounting beam 12 can be integrally formed with the connecting portion 13.

[0273] The mounting beam 12 is provided with a first mounting portion 300, which can be understood as the first mounting portion 300 on the bracket assembly 100 can be provided on the mounting beam 12, and the mounting beam 12 carries the battery 2000 through the first mounting portion 300. In some embodiments, the mounting beam 12 can be connected to the frame 20, for example, the mounting beam 12 is connected to the frame 20 by welding, screw connection 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 carry the battery 2000 together.

[0275] In the above solution, the frame 20 may include a pair of longitudinal beams in the beam, for example, the frame 20 may include a pair of longitudinal beams in the beam of a large vehicle 10000 (such as a heavy truck). By providing the connecting portion 13, the mounting beam 12 can be effectively connected to the longitudinal beam, so that the mounting beam 12 can effectively carry the battery 2000 through the first mounting portion 300, reduce the risk of the battery 2000 falling off, and improve 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 connection portion 13 extends along the gravity direction z” can be understood as that the connection 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 this application, see Figure 7 and Figure 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 the rib 14 connects the connecting portion 13 and the mounting beam 12 .

[0281] The rib plate 14 is a component connecting the connection portion 13 and the mounting beam 12. In some embodiments, the rib plate 14 can be a component for reinforcing the structural strength of the connection portion 13, the mounting beam 12 and the longitudinal beam. In some embodiments, the rib plate 14 can be a reinforcing rib, a reinforcing beam or a reinforcing rib disposed between the connection portion 13 and the mounting beam 12.

[0282] In some embodiments, the rib plate 14 can be connected to the connecting portion 13 by welding, screw connection or other connection methods. Or in some embodiments, the rib plate 14 can be integrally formed with the connecting portion 13. In some embodiments, the rib plate 14 can be connected to the mounting beam 12 by welding, screw connection or other connection methods. In some embodiments, see Fig. 9 , Fig. 9Schematic diagram of the partial structure of the connection part 13, the mounting beam 12, the rib plate 14 and the longitudinal beam in some embodiments of the present application. The rib plate 14 may be plate-shaped, and may be formed by two plate-shaped structural members being bonded to each other, and the two plate-shaped structural members are respectively formed with flanges 140 at one end facing the mounting beam 12, and the flanges 140 of the two plate-shaped structural members are folded toward opposite sides to be connected to the mounting beam 12 by welding or screw connection.

[0283] In the above scheme, by setting the rib 14 on the outer side of the frame 20, on the one hand, the space between the connecting part 13 and the mounting beam 12 can be reasonably utilized, and on the other hand, the structural strength of the connecting part 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 plate 14 facing the mounting beam 12, and 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 plate 14 to the portion where the battery 2000 and the first mounting portion 300 are connected to each other.

[0285] According to some embodiments of this application, see Fig.10 , Fig.10 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 plate 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 surface of the longitudinal beam.

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

[0287] “The first sub-connection portion 130 and the second sub-connection portion 131 extend from the edges of the rib plate 14 in opposite directions respectively” can be understood as, along the thickness direction of the rib plate 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 plate 14.

[0288] In some embodiments, the number of the first sub-connection part 130 may be one, and in some other embodiments, the number of the first sub-connection part 130 is multiple, and the multiple first sub-connection parts 130 are arranged at intervals along the gravity direction z. In some embodiments, the number of the second sub-connection part 131 may be one, and in some other embodiments, the number of the second sub-connection part 131 is multiple, and the multiple second sub-connection parts 131 are arranged at intervals along the gravity direction z. In some embodiments, the number of the first sub-connection part 130 is multiple, and the multiple first sub-connection parts 130 are arranged at intervals along the gravity direction z, the number of the second sub-connection part 131 is multiple, and the multiple second sub-connection parts 131 are arranged at intervals along the gravity direction z, and the first sub-connection part 130 and the second sub-connection part 131 are arranged in a staggered manner.

[0289] In some embodiments, see Fig. 9 The mounting unit 11 may further include a reinforcing sheet 17, which includes 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 arranged opposite to each other along the longitudinal direction y of the vehicle frame, and an avoidance gap is formed between the second portion 171 and the third portion 172. The avoidance gap can avoid the rib plate 14 so that the second portion 171 and the third portion 172 can be located on opposite sides of the rib plate 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 passing through the first sub-connection part 130 by a screw, and the third part 172 is connected to the outer side surface of the longitudinal beam by passing through the second sub-connection part 131 by a screw.

[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 plate 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 plate 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 this application, see Figure 7 The bracket 10 includes a plurality of mounting units 11, which are arranged at intervals along the longitudinal direction y of the frame. The bracket 10 also includes a connecting beam 15, which extends along the longitudinal direction y of the frame and connects two adjacent mounting units 11.

[0292] See also Figure 7 , along the longitudinal direction y of the frame, a plurality of mounting units 11 are arranged at intervals. In some embodiments, the battery 2000 may be located between two adjacent mounting units 11. In some embodiments, the number of mounting units 11 may be two, three, or four. Figure 7 , the number of mounting units 11 is four. In some embodiments, the gaps between two adjacent mounting units 11 may be equal or unequal.

[0293] See also Figure 7 The bracket 10 also includes a connecting beam 15 , which is a beam structure. The connecting beam 15 connects two adjacent mounting units 11 , and 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 be connected to the ends of two adjacent mounting beams 12. In some embodiments, the connecting beam 15 can be connected to the ends of two adjacent ribs 14. In some embodiments, the connecting beam 15 can be connected to the ends of two adjacent connecting portions 13. In some embodiments, the number of connecting beams 15 can be multiple, and some connecting beams 15 can be connected to the ends of two adjacent ribs 14, some connecting beams 15 can be connected to the ends of two adjacent ribs 14, and some connecting beams 15 can be connected 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 battery 2000 can be improved, the risk of the battery 2000 falling off can be reduced, and the driving reliability of the vehicle body 1000 can be improved.

[0297] According to some embodiments of this application, see Fig.10 and Fig.11 . Fig.11 This 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 lateral direction x of the frame may be the arrangement direction of a 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 to correspond to the two longitudinal beams, namely, the first longitudinal beam 21 and the second longitudinal beam 22. One of the connecting portions 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] See also Fig.11 , part of the mounting beam 12 may be between a pair of longitudinal beams, and the rest of the mounting beam 12 may be located on both sides of the pair of longitudinal beams (for example, part of the mounting beam 12 exceeds the first longitudinal beam 21, and part of the mounting beam 12 exceeds the second longitudinal beam 22). In some embodiments, at least one first mounting portion 300 may be provided on the part of the mounting beam 12 located between the pair of longitudinal beams. At least one first mounting portion 300 may be provided on the part of the mounting beam 12 exceeding the first longitudinal beam 21. At least one first mounting portion 300 may be provided on the part of the mounting beam 12 exceeding the second longitudinal beam 22.

[0303] In some embodiments, a plurality of mounting units 11 are spaced apart along the longitudinal direction y of the vehicle frame, and a receiving space 100 a can be 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 may be at least three, so as to form at least two accommodating spaces 100a arranged along the longitudinal direction y of the frame. Each accommodating space 100a is independent of each other. Each accommodating space 100a may be used to accommodate a battery 2000, and the battery 2000 located in the accommodating space 100a may be connected by a group of first mounting parts 300 in the accommodating 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, see Fig.12 , Fig.12 Schematic diagrams 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 that the mounting unit 11 includes a mounting beam 12 and a connecting portion 13. The mounting beam 12 can be located on the outside of the longitudinal beam, and the connecting portion 13 is located on the outside of the longitudinal beam and connects the outer side 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 frame 20, that is, when the number of brackets 10 in the vehicle body 1000 is one, the one bracket 10 can be set on one side of the 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 that 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 scheme, 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, a bracket 10 can be stably located 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, the upper limit of the number of battery replacement batteries 2000 is increased, and the endurance of the vehicle 10000 can be increased.

[0312] According to other embodiments of the present application, see Fig.12 The bracket 10 includes a plurality of mounting units 11 , which 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 frame, the bracket 10 includes a plurality of mounting units 11, and the mounting beams 12 in the plurality of mounting units 11 are arranged at intervals, and each mounting beam 12 is connected to a corresponding connecting portion 13. Two adjacent mounting units 11 are spaced apart from each other to form a space, and the space can accommodate part of the battery 2000, for example, along the longitudinal direction y of the 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. Fig.12 , four mounting units 11 are arranged at intervals to form three spaces.

[0315] In some embodiments, the battery 2000 may be in the shape of a long strip or a rectangle. The battery 2000 may extend along the longitudinal direction y of the frame, and one battery 2000 may be mounted on a vehicle by one bracket 10. Fig.12 Two brackets 10 are arranged on both sides of the frame 20, so that two batteries 2000 can be carried. The two batteries 2000 are arranged along the horizontal direction x of the frame.

[0316] In the above scheme, in the longitudinal direction y of the frame, the bracket 10 is provided with multiple mounting units 11 to form multiple spaces to accommodate the batteries 2000, reducing the risk of the batteries 2000 occupying the external space and causing space 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 according to the transverse direction x of the frame, and the spaces formed by the multiple mounting units 11 in one frame 20 can jointly 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 carried by two frames 20.

[0317] According to other embodiments of the present application, see Fig.13 , Fig.13 The bottom view of the frame 20 and the bracket 10 in some 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, and the second mounting portion 301 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 arranged relatively spaced apart, the cross beam 23 is located in a gap formed by the pair of longitudinal beams, and the cross beam 23 connects the first longitudinal beam 21 and the second longitudinal beam 22. The cross beam 23 can improve the structural strength of the frame 20, so that the frame 20 can effectively bear various loads inside and outside the vehicle body 1000.

[0319] The second mounting portion 301 is a component disposed on the crossbeam 23 for detachably connecting with 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 can achieve detachable connection with 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 a plurality of cross beams 23. The plurality of cross beams 23 may be provided with a plurality of sets of second mounting portions 301, the number of sets of the second mounting portions 301 corresponding to the number of sets of the first mounting portions 300, so that each battery 2000 may be connected by a set of first mounting portions 300 and a set of second mounting portions 301.

[0321] In the above scheme, by setting the second mounting part 301 on the cross beam 23, there is a mounting point between the battery 2000 and the cross beam 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 battery 2000 is arranged along the longitudinal direction y of the frame, multiple batteries 2000 can be arranged according to the transverse direction x of the frame. By setting the second mounting part 301 on the cross beam 23, at least one column of batteries 2000 can be carried at the corresponding position of the cross beam 23. In some embodiments, when the battery 2000 is arranged along the transverse direction x of the frame, the battery 2000 can be carried by the first mounting parts 300 on the two frames 20 and the mounting parts on the cross beam 23.

[0322] According to other embodiments of the present application, see Fig.13 The bracket assembly 100 further includes a reinforcing plate 16 , which is connected to the cross beam 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, the reinforcing plate 16 may be disposed on the lower surface of the beam 23. The reinforcing plate 16 is provided with 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 frame, opposite ends of the reinforcing plate 16 may be connected to a pair of longitudinal beams of the 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 this application, see 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 inside. 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 this application, see Figure 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 frame may be the arrangement direction of a pair of longitudinal beams in the frame 20, or the transverse direction x of the frame may be the width direction of the vehicle 10000. “Along the transverse direction x of the frame, the projection of the bracket 10 and the projection of the frame 20 at least partially overlap” can be understood as, in the height direction (i.e., the gravity direction z), the bracket 10 utilizes the space where the frame 20 is located. Alternatively, it can be understood that, among brackets 10 of the same specification, by lifting the bracket 10 upward so that the projection of the bracket 10 in the transverse direction x of the frame falls on the 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, and the impact of the installation of the bracket 10 on the ground clearance of the vehicle body 1000 can be reduced, thereby improving the driving reliability of the vehicle body 1000.

[0332] According to some embodiments of this application, see Fig.14 , Fig.14 It is a front view of the bracket 10 and the frame 20 in some embodiments of the present application. The bracket 10 has an escape groove 10a which is open upwards, and at least a part of the frame 20 is accommodated in the escape groove 10a.

[0333] In some embodiments, “open upward” may mean that when the vehicle body 1000 is located on the ground, the bracket 10 may be installed from below the 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, it is used 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] For some other embodiments, see Fig.15 , Fig.15 This is a front view of the bracket 10 and the frame 20 in some other embodiments of the present application. Fig.15 In the embodiment, 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 a 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 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 frame 20 is located.

[0337] In the above scheme, 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 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 groove 10a, and the frame 20 can be connected to the bottom wall of the avoidance groove 10a by welding, riveting, screw connection or other connection methods. In some embodiments, the frame 20 can be connected to the side walls of the avoidance groove 10a, and the frame 20 can be connected to the side walls of the avoidance groove 10a by welding, riveting, screw connection or other connection methods. In some embodiments, the frame 20 can be connected to the side walls and bottom wall of the avoidance groove 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 the 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 this application, see Figure 2 , the first connector 200 is installed on the bracket assembly 100 .

[0342] In some embodiments, the first connector 200 may be mounted on the bracket assembly 100 by bonding, welding, riveting or screw connection. Alternatively, the first connector 200 may be mounted on 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 at the same time, thereby improving the battery replacement efficiency.

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

[0345] According to some embodiments of this application, see Fig.16 , Fig.16 1 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 compartment 400 for carrying goods. The bracket assembly 100 is disposed below the cargo compartment 400 and can bear the load of the cargo compartment 400 and the goods in the cargo compartment 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 may be a vehicle body 1000 with freight properties, which may include a cargo box for carrying cargo, for example, the vehicle body 1000 may be a 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 reasonably utilized. Compared with the current backpack-style 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 the space in the length direction of the vehicle 10000, reduce the occupation of the space where the cargo box is located, 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, which includes the vehicle body 1000 described above and at least one battery 2000. Each battery 2000 is detachably connected to a set of first mounting parts 300, and the second connector of each battery 2000 is connected to a first connector 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 the cost of battery replacement.

[0351] According to some embodiments of this application, see Figure 3 and Fig.17 . Fig.17 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. Figure 3 and Fig.17 In the height direction, the upper surface of the battery 2000 can be a concave-convex surface, and the concave part forms an 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 setting 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 is increased, and a longer driving range is provided for the vehicle 10000.

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

[0356] The transverse direction x of the frame may be the arrangement direction of a pair of longitudinal beams in the frame 20, or may 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” may be understood as, in the height direction, the battery 2000 has an upwardly protruding portion, and the projection of the protruding portion in the transverse direction x of the frame can fall on 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” may also be understood as, in the height direction, the battery 2000 can utilize the space where the frame 20 is located.

[0357] In the above solution, the lateral direction x of the frame can be perpendicular to the driving direction of the vehicle 10000, and can also be understood as the width direction of the vehicle 10000. Along the lateral direction x of the frame, by arranging the projection of the battery 2000 to at least partially overlap with the projection of the frame 20, the battery 2000 can reasonably 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 frame 20. The battery 2000 includes a box and a plurality of battery cells disposed in the box, and along the lateral direction x of the frame, the projection of at least a portion of the battery cells overlaps with the projection of the frame 20.

[0359] The battery 2000 may include a housing and a battery cell. The volume of the battery cell 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 lateral direction x of the frame can be perpendicular to the driving direction of the vehicle 10000, and can also be understood as the width direction of the vehicle 10000. Along the lateral direction x of the frame, by arranging at least a portion of the battery cells in the battery 2000 so that the projection at least partially overlaps with the projection of the frame 20, the at least a portion of the battery cells can reasonably 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 scheme, 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, vehicle 10000 is a heavy truck.

[0366] In some embodiments, the heavy-duty truck may be a heavy-duty truck, which requires different capacities of batteries 2000 when transporting different goods or on different transportation routes (for example, one battery 2000 is required for short-distance endurance requirements, two batteries 2000 are required for medium-distance endurance requirements, and three batteries 2000 are required for long-distance endurance requirements). 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. Figure 1-Figure 16 .

[0368] The vehicle body 1000 can be applied to heavy trucks, that is, heavy trucks. When heavy trucks transport different goods or different transportation routes, the required capacity of the battery 2000 is different. For example, under the short-distance endurance requirement, a 200-degree battery 2000 (for example, one battery 2000) is required, and under the medium-distance endurance requirement, a 400-degree battery 2000 (for example, two batteries 2000) is required. Under the long-distance endurance requirement, 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 cooling connector.

[0369] The bracket assembly 100 includes a frame 20 and a bracket 10. The frame 20 may be a beam of a heavy truck. The frame 20 may include a first longitudinal beam 21 and a second longitudinal beam 22. The first longitudinal beam 21 and the second longitudinal beam 22 are arranged at intervals along the transverse direction x of the frame, and the first longitudinal beam 21 and the second longitudinal beam 22 extend along the longitudinal direction y of the frame. The bracket 10 is arranged on the first longitudinal beam 21 and the second longitudinal beam 22. A plurality of groups of first mounting parts 300 are arranged on the bracket 10. Each group of first mounting parts 300 is used to detachably connect a battery 2000. The number of first connectors 200 is equal to the number of groups of first mounting parts 300. Each first connector 200 is used to connect to a second connector of a battery 2000. In some embodiments, three groups of first mounting parts 300 are arranged on the bracket 10. The number of first connectors 200 may be three.

[0370] See also Figure 2 The bracket 10 has three accommodating spaces 100a, which are arranged along the first direction. Each accommodating space 100a is used to accommodate a battery 2000, and each accommodating space 100a is correspondingly provided with a set of first mounting parts 300. 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. A battery 2000 can be accommodated in the first subspace 100b, the second subspace 100c and the third subspace 100d respectively, so as to be evenly arranged on the bracket 10 under force.

[0371] See also Figure 7 and Figure 8The bracket 10 includes a plurality of mounting units 11. The plurality of mounting units 11 are arranged at intervals along a first direction, and a receiving space 100a is formed between two adjacent mounting units 11. The mounting unit 11 includes a mounting beam 12, a connecting portion 13, and a rib plate 14. The mounting beam 12 extends along the transverse direction x of the frame, a portion of the mounting beam 12 is located between the first longitudinal beam 21 and the second longitudinal beam 22, a portion of the mounting beam 12 exceeds the first longitudinal beam 21, and a portion of the mounting beam 12 exceeds the second longitudinal beam 22. A plurality of first mounting portions 300 are arranged on the mounting beam 12. Two adjacent mounting units 11 can carry a battery 2000. In some embodiments, a group of first mounting portions 300 can be arranged on the mounting beams 12 of two adjacent mounting units 11. Each mounting unit 11 includes two connecting portions 13, the two connecting portions 13 are arranged at intervals along the transverse direction x of the frame, a pair of longitudinal beams are located between the two connecting portions 13, and each connecting portion 13 is connected to the outer side surface of the 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 a plurality of first connectors 200 and setting a plurality of 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 battery life requirements (that is, replacement on demand). For example, for short-distance battery life requirements, only one battery 2000 is replaced, that is, one battery 2000 is carried; for medium-distance battery life requirements, only two batteries 2000 are replaced, that is, two batteries 2000 are carried; for long-distance battery life 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.
