[0001] This application is a divisional application based on the invention with application number 202310798138.X, application date June 30, 2023, applicant CATL, and invention title "bracket, bracket assembly and vehicle". Technical Field

[0002] This application relates to the field of new energy vehicle technology, and more specifically, to a bracket, a bracket assembly, and a vehicle. Background Technology

[0003] 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 driving range of new energy vehicles are also increasing. In order to meet the needs of new energy vehicles to replenish power loss in a timely manner during driving, the solution of battery swapping to replenish power loss in a timely manner has emerged.

[0004] For new energy vehicles, reducing battery swapping costs is a pressing technical problem that needs to be solved. Summary of the Invention

[0005] This application provides a bracket, a bracket assembly, and a vehicle that can effectively reduce battery swapping costs.

[0006] This application is achieved through the following technical solution: In one aspect, this application provides a bracket for mounting on a vehicle frame, the bracket having multiple sets of mounting parts, each set of mounting parts for detachably connecting a battery.

[0007] In the above solution, the bracket can be installed on the vehicle frame. By setting multiple mounting points on the frame, the number of batteries that need to be replaced can be adjusted according to different range requirements (that is, battery swapping on demand; for example, when the required range is short, a smaller number of batteries can be installed on the corresponding number of mounting points in the multiple mounting points; when the required range is long, a larger number of batteries can be installed on the corresponding number of mounting points in the multiple mounting points), thereby saving the cost of additional batteries and effectively reducing the vehicle's battery swapping cost.

[0008] According to some embodiments of this application, the bracket has multiple receiving spaces arranged along a first direction, each receiving space is used to receive a battery, and each receiving space is provided with a set of mounting parts.

[0009] In the above scheme, by setting multiple accommodating spaces in the first direction, and each accommodating space is equipped with a set of 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 swapping efficiency.

[0010] According to some embodiments of this application, the housing space has a downward-opening opening for the battery to enter or leave the housing space.

[0011] In the above solution, by setting a downward-opening opening, it is easy for the battery to enter or leave the storage space from below the frame, which can save space above the frame and reduce the risk of the battery swapping mechanism interfering with the vehicle and causing damage due to its occupation of space above the frame during battery swapping.

[0012] According to some embodiments of this application, the mounting portion is disposed at at least one end of the accommodating space along a first direction.

[0013] In the above solution, by placing the mounting part at at least one end of the accommodating space in the first direction, the connected battery can be effectively constrained in the first direction, reducing the risk of battery detachment and improving the driving reliability of the vehicle.

[0014] According to some embodiments of this application, the mounting portion is disposed at opposite ends of the receiving space along a first direction.

[0015] In the above solution, by placing the mounting part at one 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 subjected to uniform force, reducing the risk of battery detachment and improving the driving reliability of the vehicle.

[0016] According to some embodiments of this application, the accommodating space has a first end and a second end opposite to each other along a first direction, and the mounting part disposed at the first end and the mounting part disposed at the second end are offset from each other.

[0017] In the above solution, by staggering the mounting parts located at opposite ends of the accommodating space, on the one hand, it has a foolproof effect on battery installation, reducing the risk of incorrect battery installation; on the other hand, it has a foolproof effect on bracket installation, reducing the risk of incorrect bracket installation.

[0018] According to some embodiments of this application, the mounting portions of two adjacent accommodating spaces are staggered at the ends that are close to each other.

[0019] In the above scheme, during battery swapping, multiple battery swapping actuators (such as battery swapping bits) can simultaneously act on multiple mounting parts and the parts connected to the battery. Since two adjacent housing spaces are close to each other in the first direction, by staggering the mounting parts at the close ends of two adjacent housing spaces, the risk of interference between adjacent battery swapping actuators can be reduced, allowing multiple battery swapping actuators to work simultaneously and improving battery swapping efficiency.

[0020] According to some embodiments of this application, the size of the accommodating space along the first direction is smaller than the size along the second direction, and the first direction, the second direction, and the gravity direction are perpendicular to each other.

[0021] In the above scheme, the dimension of the accommodating space along the first direction is smaller than the dimension along the second direction. This can be understood as the dimension of the battery cell accommodated in the accommodating space along the first direction being smaller than the dimension along the second direction, meaning the dimension of the battery in the second direction can be the length of the battery. Therefore, when the mounting part is disposed at at least one end of the accommodating space along the first direction, it can be understood that the mounting part corresponds to the two sides of the shorter dimension of the battery, which, compared to the two sides corresponding to the longer dimension of the battery, can reduce the risk of the battery collapsing downwards due to gravity in the middle, and improve the connection stability between the battery and the bracket.

[0022] According to some embodiments of this application, the bracket includes multiple mounting beams, which are spaced apart along a first direction. Each mounting beam extends along a second direction, and an accommodating space is formed between two adjacent mounting beams. The mounting part is disposed on the mounting beam, and the second direction is perpendicular to the first direction.

[0023] In the above solution, on the one hand, by setting the mounting part on the mounting beam and arranging multiple mounting beams at intervals along the first direction, the multiple mounting beams can jointly bear the weight of the battery, which can effectively reduce the risk of the battery falling off; on the other hand, by arranging multiple mounting beams at intervals along the first direction, multiple batteries can be carried in an orderly manner in the first direction, thereby improving the battery swapping efficiency.

[0024] According to some embodiments of this application, the bracket further includes a connecting portion connected to the mounting beam, the connecting portion being used to connect to the longitudinal beam of the vehicle frame.

[0025] In the above solution, by setting up a connecting part, the mounting beam can be effectively connected to the longitudinal beam of the frame, so that the mounting beam can effectively support the battery through the mounting part, reducing the risk of battery detachment and improving the driving reliability of the vehicle.

[0026] According to some embodiments of this application, each mounting beam is provided with two connecting parts, the two connecting parts are spaced apart along a second direction, and the two connecting parts and the mounting beam together form an upward-opening groove for the vehicle frame to pass through.

[0027] In the above solution, by setting two connecting parts, on the one hand, it can form a groove to avoid the longitudinal beams of the frame; on the other hand, it can connect the connecting parts to the outer side of the corresponding longitudinal beams, that is, the two longitudinal beams of the frame are respectively connected by the corresponding connecting parts, so that the mounting unit and the frame have a stable connection relationship, reducing the risk of battery detachment and improving the reliability of vehicle operation. Furthermore, since there are two connecting parts, and the two connecting parts are set laterally along the frame, the mounting beam can be set with more mounting parts to mount larger batteries, thereby effectively improving the vehicle's range. Moreover, the groove is a part for the frame to pass through, so the second direction can be regarded as the arrangement direction of a pair of longitudinal beams of the frame, that is, the transverse direction of the frame. Therefore, the battery can be set according to the transverse direction of the frame, and multiple batteries can be arranged according to the longitudinal direction of the frame, so as to make the center of gravity of the battery as close as possible to the center of the vehicle, improving the reliability of vehicle operation.

[0028] According to some embodiments of this application, the bracket further includes a rib plate located on the side of the connector opposite to the groove, the rib plate connecting the connector and the mounting beam.

[0029] In the above solution, by setting ribs on the outside of the frame, the space between the connecting part and the mounting beam can be made reasonable, and the structural strength of the connecting part and the mounting beam can be improved, reducing the risk of battery detachment and improving the driving reliability of the vehicle.

[0030] According to some embodiments of this application, a bent portion is provided at one end of the rib plate near the mounting beam, and the rib plate is connected to the mounting beam through the bent portion.

[0031] In the above scheme, by setting a bend at the end of the rib near the load beam, the connection area between the rib and the load beam can be increased, thereby improving the connection stability between the rib and the load beam.

[0032] According to some embodiments of this application, a notch is formed at one end of the rib plate near the mounting beam, and the notch is provided corresponding to the mounting part.

[0033] In the above solution, by setting a notch at one end of the rib plate near the mounting beam, space above the mounting part can be left free, reducing the risk of the battery being interfered with by the rib plate when mounted on the mounting part.

[0034] According to some embodiments of this application, the rib plate and the mounting beam are integrally formed.

[0035] In the above scheme, the rib plate and the mounting beam are integrally formed (for example, the rib plate and the mounting beam are formed by a roll forming process). Therefore, the rib plate and the mounting beam have high structural strength, can effectively support the battery, reduce the risk of battery detachment, and improve the driving reliability of the vehicle.

[0036] According to some embodiments of this application, the mounting beam and the rib plate are separate structures.

[0037] In the above scheme, the mounting beam and rib plate can be separate structures, and the two can be connected by simple processes (such as welding, riveting, threaded connection or other methods), which can effectively reduce the manufacturing difficulty and cost of the bracket.

[0038] According to some embodiments of this application, the plurality of mounting beams include a first mounting beam and a second mounting beam located in the middle. The first mounting beam is provided with a plurality of connecting portions spaced apart along a second direction, and the second mounting beam is provided with a plurality of connecting portions spaced apart along a second direction. A channel for the vehicle frame to pass through is formed between the connecting portions on the first mounting beam and the connecting portions on the second mounting beam. The connecting portions are used to connect with the longitudinal beams of the vehicle frame.

[0039] In the above solution, by setting multiple connecting parts spaced apart along the second direction on the first mounting beam and multiple connecting parts spaced apart along the second direction on the second mounting beam, and forming a channel for the frame to pass through between the connecting parts on the first mounting beam and the connecting parts on the second mounting beam, the first direction can be defined as the transverse direction of the frame (that is, the arrangement direction of a pair of longitudinal beams of the frame), thereby defining the battery to be arranged along the longitudinal direction of the frame and multiple batteries to be arranged along the transverse direction of the frame, providing more options for battery layout and thus improving the compatibility of the bracket.

[0040] According to some embodiments of this application, the bracket further includes a first connecting beam that extends along a first direction and connects two adjacent mounting beams.

[0041] In the above solution, by setting a first connecting beam, two adjacent mounting beams are connected to each other, thereby improving the structural stability of the two adjacent mounting beams, effectively supporting the battery, reducing the risk of battery detachment, and improving the vehicle's driving stability.

[0042] According to some embodiments of this application, the bracket further includes a rib plate located on the side of the connector opposite to the channel, the rib plate connecting the connector and the first connecting beam.

[0043] In the above solution, by setting ribs on the outside of the frame, the space on the outside of the frame can be made reasonable, and the structural strength of the connecting part and the first connecting beam can be improved, thereby improving the structural strength of the mounting beam, reducing the risk of battery detachment, and improving the driving reliability of the vehicle.

[0044] According to some embodiments of this application, the connecting portion extends along the direction of gravity.

[0045] In the above solution, by setting the connecting part to extend along the direction of gravity, the connecting part has a larger area in the direction of gravity to connect with the longitudinal beam, thereby improving the connection stability between the mounting beam and the longitudinal beam, reducing the risk of battery detachment, and improving the driving reliability of the vehicle.

[0046] According to some embodiments of this application, the connecting part is a flange of a rib plate, and the rib plate and the connecting part are arranged perpendicular to each other.

[0047] In the above scheme, the connecting part can be the flange of the rib plate, that is, the connecting part and the rib plate are integrally formed, which can make the connecting part and the rib plate have high structural strength, effectively provide structural strength for the mounting beam, thereby effectively supporting the battery and reducing the risk of battery falling off.

[0048] According to some embodiments of this application, the rib includes a first rib and a second rib stacked together, and the connecting portion includes a first sub-connecting portion and a second sub-connecting portion, wherein the first sub-connecting portion is the flange of the first rib and the second sub-connecting portion is the flange of the second rib.

[0049] In the above scheme, the rib can be a double-layer plate structure. Since the rib is a double-layer plate structure, the rib can form two flanges facing opposite directions, that is, form the first sub-connection part and the second sub-connection part, so that there is a large connection area between the rib and the longitudinal beam, improving the connection stability between the rib and the longitudinal beam, thereby improving the structural strength of the mounting beam, enabling the mounting beam to effectively support the battery and reducing the risk of battery falling off.

[0050] According to some embodiments of this application, the bracket further includes a second connecting beam that connects two adjacent connecting portions.

[0051] In the above solution, by setting a second connecting beam to connect two adjacent connecting parts, the structural stability of the connecting parts can be improved, thereby improving the structural stability of the bracket, reducing the risk of battery detachment, and improving the driving stability of the vehicle.

[0052] According to some embodiments of this application, a reinforcing plate is provided on the connecting part, and the reinforcing plate is used to connect the vehicle frame.

[0053] In the above solution, the structural strength of the connection part can be effectively improved by setting the reinforcing plate, the connection stability between the connection part and the frame can be improved, thereby improving the structural stability of the bracket, reducing the risk of battery detachment, and improving the driving stability of the vehicle.

[0054] According to some embodiments of this application, the mounting beam is a square tube beam.

[0055] In the above scheme, by setting the mounting beam as a square tube beam, the material cost is low, and the material structure has high strength, which can effectively support the battery and reduce the risk of battery detachment.

[0056] According to some embodiments of this application, two rows of mounting parts are provided on the two middle mounting beams of a plurality of mounting beams, and the two rows of mounting parts are staggered.

[0057] In the above scheme, during battery swapping, multiple battery swapping actuators (such as battery swapping bits) can simultaneously act on multiple mounting parts connected to the batteries. The two mounting beams in the middle can mount two batteries each. By staggering the two rows of mounting parts on these two beams, the risk of interference between adjacent battery swapping actuators can be reduced, allowing multiple battery swapping actuators to work simultaneously and improving battery swapping efficiency.

[0058] According to some embodiments of this application, the mounting portion includes mounting holes formed on the mounting beam; the mounting holes penetrate the mounting beam along the direction of gravity.

[0059] In the above scheme, on the one hand, the mounting part has a simple structure and is easy to manufacture; on the other hand, because the mounting part has a simple structure, the connection between the battery and the mounting part is also simple, which can effectively improve the battery swapping efficiency.

[0060] According to some embodiments of this application, the mounting part further includes a mounting sleeve disposed within the mounting hole.

[0061] In the above solution, by setting a mounting sleeve inside the mounting hole, the structural strength of the mounting part can be improved, so that the battery can be stably connected to the bracket, reducing the risk of battery falling off and improving the driving stability of the vehicle.

[0062] Secondly, some embodiments of this application also provide a bracket assembly, which includes a bracket according to any of the first aspects and a plurality of first connectors. The plurality of first connectors are disposed on the bracket, the number of first connectors being equal to the number of mounting portions, and each first connector is used to connect to a second connector of a battery.

[0063] In the above solution, by setting multiple first connectors and multiple sets of mounting parts on the bracket, the number of batteries to be replaced can be adjusted according to the range requirement (that is, battery replacement on demand; for example, when the required range is short, a smaller number of batteries can be installed on the corresponding number of mounting parts in the multiple sets of mounting parts, and the second connector of each battery is connected to the corresponding first connector; when the required range is long, a larger number of batteries can be installed on the corresponding number of mounting parts in the multiple sets of 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.

[0064] Thirdly, some embodiments of this application also provide a vehicle including the bracket assembly provided in the second aspect and at least one battery. Each battery is detachably connected to a set of mounting parts.

[0065] The above solution provides a vehicle that can swap batteries on demand, that is, adjust the number of batteries to be swapped according to its own range requirements, so as to reduce the cost of battery swapping.

Obviously, the described embodiments are only some embodiments of this application, not all embodiments.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0079] Currently, new energy vehicles often use battery swapping to replenish power lost during driving. Reducing the cost of battery swapping is a pressing technical issue for new energy vehicles. Currently, new energy vehicles are equipped with a single, fixed battery with a fixed capacity, meaning the vehicle's driving range is fixed. During battery swapping, this single battery is replaced. However, different driving range requirements necessitate different battery capacities. Shorter driving ranges require smaller capacities, while larger batteries incur additional costs due to the increased capacity, resulting in higher battery swapping costs.

[0080] In view of this, to address the issue of high battery swapping costs due to varying range requirements, some embodiments of this application provide a bracket for mounting on a vehicle frame. The bracket has multiple sets of mounting parts, each set for detachably connecting a battery.

[0081] In the above solution, by setting multiple mounting points on the vehicle frame, the number of batteries that need to be replaced can be adjusted according to different range requirements (that is, battery swapping on demand; for example, when the required range is short, a smaller number of batteries can be installed on the corresponding number of mounting points in the multiple mounting points; when the required range is long, a larger number of batteries can be installed on the corresponding number of mounting points in the multiple mounting points), thereby saving the cost of additional batteries and effectively reducing the cost of battery swapping.

[0082] The brackets disclosed in this application can be, but are not limited to, installed on the frames of passenger vehicles, commercial vehicles, and other types of frames. The vehicles disclosed in this application can be, but are not limited to, used in passenger vehicles, commercial vehicles, and other types of vehicles.

[0083] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of a vehicle 10000 provided in some embodiments of this application. The vehicle 10000 can be a new energy vehicle 10000, which can be a pure electric vehicle, a battery-swapping hybrid electric vehicle, or a battery-swapping range-extended electric vehicle, etc. The vehicle 10000 includes a battery 2000. The battery 2000 can be disposed at the bottom, front, or rear of the vehicle 10000. The battery 2000 can be used to power the vehicle 10000; for example, the battery 2000 can serve as the operating power source for the vehicle 10000's electrical system, such as meeting the power requirements for starting, navigation, and operation of the vehicle 10000.

[0084] The vehicle 10000 may also include a controller 3000 and a motor 4000. The controller 3000 is used to control the battery 2000 to power the motor 4000, for example, to meet the power requirements of the vehicle 10000 during startup, navigation and driving.

[0085] In some embodiments of this application, the battery 2000 can not only serve as the operating power source for the vehicle 10000, but also as the driving power source for the vehicle 10000, replacing or partially replacing fuel or natural gas to provide driving power for the vehicle 10000.

[0086] In some embodiments, the vehicle 10000 may further include a frame 200, which may be a frame structure spanning the front and rear axles of the vehicle 10000, commonly known as a beam, and serves as the base of the vehicle 10000. The function of the frame 200 may include supporting and connecting the various assemblies of the vehicle 10000, maintaining the relatively correct position of the assemblies, and bearing various loads inside and outside the vehicle 10000.

[0087] In some embodiments, the frame 200 may include a pair of longitudinal beams, such as a first longitudinal beam 201 and a second longitudinal beam 202. The first longitudinal beam 201 and the second longitudinal beam 202 are spaced apart from each other along the transverse direction of the frame 200. The first longitudinal beam 201 and the second longitudinal beam 202 may extend along the longitudinal direction of the frame 200.

[0088] Some embodiments of this application provide a bracket 100; please refer to [the relevant documentation]. Figure 2 and Figure 3 , Figure 2 This is a top view of the bracket 100 and the frame 200 in some embodiments of this application. Figure 3 This is a perspective view of the bracket 100, the frame 200, and the battery 2000 in some embodiments of this application.

[0089] The bracket 100 is used to be mounted on the frame 200. The bracket 100 is provided with multiple sets of mounting parts 11, each set of mounting parts 11 being used to detachably connect a battery 2000.

[0090] In some embodiments, the frame 200 can be a frame structure spanning the front and rear axles of the vehicle 10000, commonly known as a beam, which is the base of the vehicle 10000. The function of the frame 200 can include supporting and connecting the various assemblies of the vehicle 10000, keeping the assemblies in a relatively correct position, and bearing various loads inside and outside the vehicle 10000.

[0091] In some embodiments, the frame 200 is located at the bottom of the vehicle 10000.

[0092] In some embodiments, the bracket 100 is a component fixed to the vehicle frame 200. In some embodiments, the bracket 100 can be connected to the vehicle frame 200 by means of welding, riveting, threaded connection, etc. In other embodiments, the bracket 100 can be integrally formed with the vehicle frame 200.

[0093] The bracket 100 is provided with a mounting portion 11, which can mount the battery 2000. In some embodiments, the bracket 100 has a certain structural strength to mount the battery 2000. In some embodiments, the material of the bracket 100 can be the same as the material of the vehicle frame 200. In some embodiments, the material of the bracket 100 can be aluminum alloy, steel, cast iron, or reinforced plastic, etc.

[0094] The mounting portion 11 is a component disposed on the bracket 100 for detachable connection with the battery 2000. The mounting portions 11 are arranged in groups, with each group corresponding to one battery 2000, for detachably mounting the corresponding battery 2000 to the bracket 100. The bracket 100 has multiple groups of mounting portions 11, meaning the bracket 100 can be detachably connected to a corresponding number of batteries 2000 through multiple groups of mounting portions 11 to achieve battery swapping of multiple batteries 2000. In some embodiments, the mounting portion 11 includes, but is not limited to, mounting holes 110, mounting threads, and other structures that enable detachable connection with the battery 2000. In some embodiments, the bracket 100 may have two, three, four, or more groups of mounting portions 11.

[0095] In the above solution, the bracket 100 can be installed on the frame 200 of the vehicle 10000. By setting multiple sets of mounting parts 11 on the frame 200, the vehicle 10000 can adjust the number of batteries 2000 that need to be replaced based on the range requirements (that is, battery swapping on demand; for example, when the required range is short, a smaller number of batteries 2000 can be installed on the corresponding number of mounting parts 11 in the multiple sets of mounting parts 11; when the required range is long, a larger number of batteries 2000 can be installed on the corresponding number of mounting parts 11 in the multiple sets of mounting parts 11), thereby saving the cost of additional batteries 2000 and effectively reducing the battery swapping cost of the vehicle 10000.

[0096] According to some embodiments of this application, the bracket 100 has a plurality of accommodating spaces 100a, the plurality of accommodating spaces 100a are arranged along a first direction x, each accommodating space 100a is used to accommodate a battery 2000, and each accommodating space 100a is correspondingly provided with a set of mounting parts 11.

[0097] In some embodiments, the bracket 100 has a plurality of receiving spaces 100a arranged along a first direction x, and the plurality of receiving spaces 100a are independent of each other. Each receiving space 100a can be used to receive a battery 2000, and the battery 2000 located in the receiving space 100a can be connected by a set of mounting parts 11 in the receiving space 100a.

[0098] The arrangement of multiple storage spaces 100a along the first direction x can be understood as the arrangement of multiple batteries 2000 along the first direction x.

[0099] In some embodiments, the receiving spaces 100a may be of the same size so that the bracket 100 can hold multiple batteries 2000 of the same specification. In other embodiments, the receiving spaces 100a may be of different sizes so that the bracket 100 can hold multiple batteries 2000 of different specifications.

[0100] In the above scheme, by setting multiple accommodating spaces 100a in the first direction x, and each accommodating space 100a is provided with a set of mounting parts 11, 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 swapping efficiency.

[0101] According to some embodiments of this application, the receiving space 100a has a downward-opening opening for the battery 2000 to enter or leave the receiving space 100a.

[0102] "The accommodating space 100a has a downward opening" can be understood as the accommodating space 100a having an opening facing the ground, for example, when the vehicle 10000 is supported on the ground, the opening of the accommodating space 100a faces the ground.

[0103] In some embodiments, the battery 2000 may enter or exit the housing space 100a through an opening.

[0104] In some embodiments, the battery swapping site may be provided with a trench, and the battery swapping mechanism may be provided in the trench. When the vehicle 10000 is in the battery swapping position, the trench may be located below the vehicle 10000, and the battery 2000 enters or leaves the accommodating space 100a through the battery swapping mechanism in the trench.

[0105] In the above solution, by setting a downward-opening opening, the battery 2000 can easily enter or leave the accommodating space 100a from below the frame 200, which can save space above the frame 200 and reduce the risk of the battery swapping mechanism occupying space above the frame 200 during battery swapping, thus interfering with the vehicle 10000 and causing damage to the vehicle 10000.

[0106] According to some embodiments of this application, the mounting portion 11 is disposed at at least one end of the accommodating space 100a along the first direction x.

[0107] "The mounting part 11 is provided at least one end of the accommodating space 100a along the first direction x" can be understood as follows: the mounting part 11 is provided at one end of the accommodating space 100a along the first direction x, or the mounting parts 11 can be provided at opposite ends of the accommodating space 100a respectively.

[0108] In the above solution, by placing the mounting part 11 at at least one end of the accommodating space 100a in the first direction x, the connected battery 2000 can be effectively constrained in the first direction x, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle 10000.

[0109] According to some embodiments of this application, the mounting portion 11 is disposed at opposite ends of the accommodating space 100a along the first direction x.

[0110] In the first direction x, mounting portions 11 are provided at both opposite ends of the accommodating space 100a. In some embodiments, the number of mounting portions 11 at opposite ends of the accommodating space 100a may be the same or different.

[0111] "The mounting part 11 is provided at opposite ends of the accommodating space 100a along the first direction x", which can also be understood as the battery 2000 being mounted and connected at opposite ends of the first direction x by the mounting part 11.

[0112] In the above solution, by setting the mounting part 11 at one end of the accommodating space 100a in the first direction x, the battery 2000 can be effectively constrained in the first direction x, so that the battery 2000 is subjected to uniform force, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle 10000.

[0113] According to some embodiments of this application, please refer to Figure 2 The accommodating space 100a has a first end 100b and a second end 100c opposite each other along the first direction x, and the mounting part 11 provided at the first end 100b and the mounting part 11 provided at the second end 100c are offset from each other.

[0114] The first end 100b and the second end 100c are two opposite portions of the receiving space 100a in the first direction x. In some embodiments, the first end 100b and the second end 100c correspond to two opposite edges of the battery 2000 in the first direction x.

[0115] The phrase "the mounting part 11 located at the first end 100b and the mounting part 11 located at the second end 100c are misaligned" can be understood as follows: along the first direction x, the projections of the mounting part 11 located at the first end 100b and the mounting part 11 located at the second end 100c do not overlap. In other words, it can be understood that if the mounting part 11 located at the first end 100b is translated along the first direction x to the second end 100c, it will not interfere with the mounting part 11 located at the second end 100c.

[0116] In the above solution, by misaligning the mounting portions 11 located at opposite ends in the accommodating space 100a, on the one hand, it provides a foolproof effect for the installation of the battery 2000, reducing the risk of incorrect installation of the battery 2000; on the other hand, it provides a visual foolproof effect for the installation of the bracket 100 (that is, when the bracket 100 is installed on the vehicle frame 200), reducing the risk of incorrect installation of the bracket 100.

[0117] According to some embodiments of this application, the mounting portions 11 of two adjacent accommodating spaces 100a are staggered at the ends closest to each other.

[0118] The phrase "the mounting portions 11 of two adjacent accommodating spaces 100a are misaligned at their closest ends" can be understood as the mounting portions 11 of two batteries 2000 in two adjacent accommodating spaces 100a being misaligned at their closest points. Please refer to [link to relevant documentation]. Figure 2 The mounting portion 11, which is located at one end of one of the accommodating spaces 100a and is closer to the other accommodating space 100a, is translated along the first direction x to the end of the other accommodating space 100a that is closer to the first accommodating space 100a, without interfering with the mounting portion 11 originally located at the end of the other accommodating space 100a that is closer to the first accommodating space 100a. That is, the mounting portions 11 at the ends of two adjacent accommodating spaces 100a are misaligned not only with each other in the first direction x, but also with a distance in a direction perpendicular to the first direction x.

[0119] In the above scheme, during battery swapping, multiple battery swapping actuators (e.g., battery swapping bits) of the battery swapping mechanism can simultaneously act on the portions of the mounting parts 11 that are connected to the battery 2000. Since two adjacent receiving spaces 100a are close to each other in the first direction x, by staggering the mounting parts 11 at the close ends of the two adjacent receiving spaces 100a, the risk of interference between the two adjacent battery swapping actuators can be reduced, allowing multiple battery swapping actuators to work simultaneously and improving battery swapping efficiency.

[0120] According to some embodiments of this application, the dimension of the accommodating space 100a along the first direction x is smaller than the dimension along the second direction y, and the first direction x, the second direction y, and the gravity direction z are perpendicular to each other.

[0121] The first direction x can be the arrangement direction of the plurality of accommodating spaces 100a, and the second direction y can be a direction perpendicular to the first direction x and perpendicular to the gravity direction z. In some embodiments, the frame 200 may include a pair of longitudinal beams, the transverse direction of the frame 200 can be the arrangement direction of the pair of longitudinal beams, and the longitudinal direction of the frame 200 can be the extension direction of the longitudinal beams. When the first direction x is the longitudinal direction of the frame 200, the second direction y can be the transverse direction of the frame 200.

[0122] In some embodiments, the accommodating space 100a can be a rectangular space, the dimension of the accommodating space 100a in the first direction x is smaller than the dimension in the second direction y, and the accommodating space 100a can accommodate a strip-shaped or rectangular battery 2000, the dimension of the battery 2000 in the first direction x can be smaller than the dimension in the second direction y.

[0123] In the above scheme, the dimension of the accommodating space 100a along the first direction x is smaller than its dimension along the second direction y. This can be understood as the dimension of the battery 2000 cell accommodated by the accommodating space 100a along the first direction x being smaller than its dimension along the second direction y. That is, the dimension of the battery 2000 in the second direction y can be the length of the battery 2000. Therefore, when the mounting part 11 is disposed at at least one end of the accommodating space 100a along the first direction x, it can be understood that the mounting part 11 corresponds to the two sides of the shorter dimension of the battery 2000. Compared with the two sides corresponding to the longer dimension of the battery 2000, this can reduce the risk of the battery 2000 collapsing downward due to gravity in the middle, and improve the connection stability between the battery 2000 and the bracket 100.

[0124] According to some embodiments of this application, please refer to Figure 2 and Figure 3 The bracket 100 includes multiple mounting beams 10, which are spaced apart along a first direction x. Each mounting beam 10 extends along a second direction y, and a receiving space 100a is formed between two adjacent mounting beams 10. The mounting part 11 is disposed on the mounting beam 10, and the second direction y is perpendicular to the first direction x.

[0125] The first direction x can be the arrangement direction of the plurality of accommodating spaces 100a, and the second direction y can be a direction perpendicular to the first direction x and perpendicular to the gravity direction z. In some embodiments, the frame 200 may include a pair of longitudinal beams, the transverse direction of the frame 200 can be the arrangement direction of the pair of longitudinal beams, and the longitudinal direction of the frame 200 can be the extension direction of the longitudinal beams. When the first direction x is the longitudinal direction of the frame 200, the second direction y can be the transverse direction of the frame 200.

[0126] The mounting beam 10 is a beam structure, which can be rod-shaped, rod-shaped, plate-shaped, or cylindrical, etc. Please refer to [link / reference]. Figure 2 The mounting beam 10 can extend along the second direction y. In some embodiments, such as Figure 2 A portion of the mounting beam 10 may be located between a pair of longitudinal beams of the frame 200, and a portion of the mounting beam 10 may be located on both sides of the frame 200 along its transverse direction. In some embodiments, the mounting beam 10 may be located on the outer side of the frame 200. In some embodiments, the mounting beam 10 may be located between a pair of longitudinal beams of the frame 200. In other embodiments, portions of the mounting beams 10 may be located on the outer side of the frame 200, and portions of the mounting beams 10 may be located between a pair of longitudinal beams of the frame 200. In other embodiments, see [link to other embodiments]. Figure 4 , Figure 4 This is a schematic diagram of the bracket 100, battery 2000, and frame 200 in other embodiments of this application. Figure 5This is a schematic diagram of the bracket 100 in some other embodiments of this application. Along the transverse direction of the frame 200, some of the mounting beams 10 of the plurality of mounting beams 10 may be located on opposite sides of the frame 200, and the other part of the mounting beams 10 may be between a pair of longitudinal beams of the frame 200.

[0127] In some embodiments, "the mounting portion 11 is provided on the mounting beam 10" can be understood as the mounting beam 10 being provided with a mounting portion 11 for detachably connecting the battery 2000. For example, it can be understood that one mounting beam 10 can be provided with a set of mounting portions 11 to mount one battery 2000. Or it can be understood that one mounting beam 10 can be provided with a partial mounting portion 11 of a set of mounting portions 11, which, in conjunction with other mounting beams 10, can mount one battery 2000. Or it can be understood that one mounting beam 10 can be provided with partial mounting portions 11 of multiple sets of mounting portions 11 (e.g., two sets of mounting portions 11), which, in conjunction with other mounting beams 10, can mount the battery 2000.

[0128] In some embodiments, the mounting beam 10 can be directly or indirectly used to connect to the vehicle frame 200. For example, the mounting beam 10 can be connected to the vehicle frame 200 by welding, riveting or threaded connection or other means, or other components can be connected to the vehicle frame 200. The mounting beam 10 is connected to the vehicle frame 200 by connecting to these other components.

[0129] In some embodiments, two mounting beams 10 are spaced apart along a first direction x to form a receiving space 100a. When the bracket 100 is mounted on the vehicle frame 200, a battery 2000 can be accommodated in the receiving space 100a. In the first direction x, the batteries 2000 can be mounted on both sides of the receiving space 100a by the mounting beams 10.

[0130] In some embodiments, the number of mounting beams 10 is at least three, so as to form at least two batteries 2000 in the first direction x, and the batteries 2000 can be accommodated in the corresponding accommodating space 100a.

[0131] Please see Figure 2 There are four mounting beams 10, which are spaced apart along the first direction x to form three accommodating spaces 100a for mounting three batteries 2000. In the first direction x, the two outermost mounting beams 10 are each provided with a partial mounting portion 11 of a mounting section 11. The two middle mounting beams 10 are each provided with two partial mounting portions 11 of the mounting section 11.

[0132] In the above solution, on the one hand, by setting the mounting part 11 on the mounting beam 10 and arranging multiple mounting beams 10 at intervals along the first direction x, the multiple mounting beams 10 can jointly bear the weight of the battery 2000, which can effectively reduce the risk of the battery 2000 falling off; on the other hand, by arranging multiple mounting beams 10 at intervals along the first direction x, multiple batteries 2000 can be carried in an orderly manner in the first direction x, thereby improving the battery swapping efficiency.

[0133] According to some embodiments of this application, please refer to Figure 6 and Figure 7 , Figure 6 This is a perspective view of the bracket 100 in some embodiments of this application. Figure 7 for Figure 6 Enlarged view at point A. The bracket 100 also includes a connecting part 20, which is connected to the mounting beam 10 and is used to connect with the longitudinal beam of the frame 200.

[0134] In some embodiments, the connecting portion 20 may be connected to the outer side of a longitudinal beam of the frame 200. The side of the longitudinal beam facing another longitudinal beam may be the inner side, and the side of the longitudinal beam away from another longitudinal beam may be the outer side. In some embodiments, the connecting portion 20 may be connected to the frame 200 by welding, threaded connection, or other connection methods.

[0135] The mounting beam 10 is directly or indirectly connected to the connecting part 20 so that the mounting beam 10 can be connected to the frame 200. In some embodiments, the mounting beam 10 can be connected to the connecting part 20 by welding, riveting, threaded connection or other connection methods. In some embodiments, the mounting beam 10 can be integrally formed with the connecting part 20.

[0136] In the above solution, by setting the connecting part 20, the mounting beam 10 can be effectively connected to the longitudinal beam of the frame 200, so that the mounting beam 10 can effectively support the battery 2000 through the mounting part 11, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle 10000.

[0137] According to some embodiments of this application, please refer to Figure 8 , Figure 8 This is a schematic diagram of the mounting beam 10 and the connecting portion 20 in some embodiments of this application. Each mounting beam 10 is provided with two connecting portions 20, which are spaced apart along the second direction y. The two connecting portions 20 and the mounting beam 10 together form an upwardly opening groove 21 (see [link to documentation]). Figure 8 The groove 21 is for the frame 200 to pass through.

[0138] In some embodiments, each mounting beam 10 is provided with two connecting portions 20, and the two connecting portions 20 are spaced apart in the second direction y, so that the two connecting portions 20 are respectively connected to a pair of longitudinal beams of the frame 200, such as the outer side of a pair of longitudinal beams. That is, it can be understood that the two connecting portions 20 on each mounting beam 10 are respectively located on the outer side of the frame 200.

[0139] "The groove 21 is for the frame 200 to pass through" can be understood as the longitudinal beam of the frame 200 can pass through the groove 21 formed between the two connecting parts 20 on each mounting beam 10. That is, the second direction y can be the transverse direction of the frame 200, and the first direction x can be the longitudinal direction of the frame 200. In other words, multiple batteries 2000 can be arranged along the longitudinal direction of the frame 200, and the batteries 2000 can be arranged along the transverse direction of the frame 200.

[0140] In the above solution, by setting two connecting parts 20, on the one hand, it can form a groove 21 that avoids the longitudinal beam of the frame 200; on the other hand, it can make the connecting parts 20 connect to the outer side of the corresponding longitudinal beam, that is, the two longitudinal beams of the frame 200 are respectively connected by the corresponding connecting parts 20, so that there is a stable connection between the mounting unit and the frame 200, reducing the risk of the battery 2000 falling off and improving the reliability of the vehicle 10000 driving; furthermore, since there are two connecting parts 20, and the two connecting parts 20 are arranged laterally along the frame 200, that is, the mounting beam 1 The vehicle 10000 can be equipped with more mounting parts 11 to mount larger batteries 2000, thereby effectively improving the range of the vehicle 10000. On the other hand, the groove 21 is the part through which the frame 200 passes, so the second direction y can be regarded as the arrangement direction of a pair of longitudinal beams of the frame 200, that is, the transverse direction of the frame 200. Therefore, the batteries 2000 can be arranged in the transverse direction of the frame 200, and multiple batteries 2000 can be arranged in the longitudinal direction of the frame 200, so as to make the center of gravity of the batteries 2000 as close as possible to the center of the vehicle 10000, thereby improving the driving reliability of the vehicle 10000.

[0141] According to some embodiments of this application, please refer to Figures 6-8 The bracket 100 also includes a rib 30, which is located on the side of the connecting part 20 away from the groove 21. The rib 30 connects the connecting part 20 and the hanging beam 10.

[0142] In some embodiments, the rib 30 may be a component connecting the connecting portion 20 and the mounting beam 10. In some embodiments, the rib 30 may be a component for strengthening the structural strength of the connecting portion 20, the mounting beam 10, and the frame 200. In some embodiments, the rib 30 may be a reinforcing rib, reinforcing beam, or reinforcing rib disposed between the connecting portion 20 and the mounting beam 10. In some embodiments, the rib 30 may be made of materials such as aluminum alloy, steel, or cast iron. In some embodiments, the materials of the rib 30, the connecting portion 20, and the mounting beam 10 may be the same or different.

[0143] In some embodiments, the rib 30 can be connected to the connecting portion 20 by welding, threaded connection, or other connection methods. Alternatively, in some embodiments, the rib 30 can be integrally formed with the connecting portion 20. In some embodiments, the rib 30 can be connected to the mounting beam 10 by welding, threaded connection, or other connection methods. Alternatively, in some embodiments, the rib 30 can be integrally formed with both the connecting portion 20 and the mounting beam 10.

[0144] In the above solution, by setting ribs 30 on the outside of the frame 200, the space between the connecting part 20 and the mounting beam 10 can be made reasonable, and the structural strength of the connecting part 20 and the mounting beam 10 can be improved, reducing the risk of the battery 2000 falling off and improving the driving reliability of the vehicle 10000.

[0145] According to other embodiments of this application, please refer to Figure 9 , Figure 9 This is a schematic diagram of a partial structure of the rib plate 30 and the mounting beam 10 in other embodiments of this application.

[0146] The rib plate 30 has a bent portion 31 at one end near the mounting beam 10, and the rib plate 30 is connected to the mounting beam 10 through the bent portion 31.

[0147] The bent portion 31 is a component provided at one end of the rib 30 near the mounting beam 10. The bent portion 31 can be a component formed by bending the rib 30, and the bent portion 31 can be perpendicular to the main body of the rib 30. The bent portion 31 has a surface facing the mounting beam 10, which can be connected to the surface of the mounting beam 10.

[0148] In some embodiments, the rib 30 can be a double-layer plate structure, which can be composed of two plate-like structures stacked together. One plate-like structure is bent to form a bent portion 31, which is connected to the mounting beam 10. The other plate-like structure is bent to form a bent portion 31, which is also connected to the mounting beam 10. The bent portions 31 of the two plate-like structures are bent in opposite directions, for example, along the thickness direction of the rib 30, towards both sides of the rib 30.

[0149] In the above scheme, by providing a bending portion 31 at the end of the rib plate 30 near the mounting beam 10, the connection area between the rib plate 30 and the mounting beam 10 can be increased, thereby improving the connection stability between the rib plate 30 and the mounting beam 10.

[0150] According to some embodiments of this application, please refer to Figure 7 and Figure 9 The rib plate 30 has a notch 32 at one end near the mounting beam 10, and the notch 32 is provided corresponding to the mounting part 11.

[0151] The notch 32 can be a recessed structure (or a groove-like structure) formed at the end of the rib 30. The notch 32 is provided corresponding to the mounting portion 11, providing space above the mounting portion 11. In some embodiments, the mounting portion 11 includes a mounting hole 110 formed on the mounting beam 10, and in the second direction y, the size of the notch 32 can be greater than or equal to the size of the mounting hole 110. In some embodiments, the battery 2000 has a mounting member corresponding to the mounting hole 110, which is inserted into the mounting hole 110 to connect the battery 2000 and the bracket 100. In the height direction, the dimension of the mounting member extending beyond the upper surface of the mounting beam 10 is less than or equal to the distance from the bottom of the notch 32 to the upper surface of the mounting beam 10.

[0152] In the above solution, by setting a notch 32 at one end of the rib plate 30 near the mounting beam 10, space above the mounting part 11 can be left free, reducing the risk of the battery 2000 being interfered with by the rib plate 30 when it is mounted on the mounting part 11.

[0153] According to some embodiments of this application, the rib plate 30 and the mounting beam 10 are integrally formed.

[0154] Roll forming is a process that relies on the plastic movement properties of materials to form various complex parts using the principle of rolling extrusion. In some embodiments, please refer to... Figure 8 The rib 30 and the mounting beam 10 can be manufactured from a single sheet material using a roll forming process. The connecting portion 20 can also be a part of this sheet material, and can be formed by bending the end of the rib 30. See also... Figure 8 The connecting portion 20 may include a plurality of sub-connecting blocks 24, which are arranged at intervals along the gravitational direction z, and two adjacent sub-connecting blocks 24 may be located on opposite sides of the rib 30. The sub-connecting blocks 24 can be formed by shearing and bending the rib 30.

[0155] In other embodiments, the rib plate 30 and the mounting beam 10 can also be integrally formed by casting.

[0156] In the above scheme, the rib plate 30 and the mounting beam 10 are integrally formed (for example, the rib plate 30 and the mounting beam 10 are formed by roll forming process). Therefore, the rib plate 30 and the mounting beam 10 have high structural strength, can effectively support the battery 2000, reduce the risk of the battery 2000 falling off, and improve the driving reliability of the vehicle 10000.

[0157] According to some embodiments of this application, the mounting beam 10 and the rib plate 30 are separate structures.

[0158] Please see Figure 9 The mounting beam 10 and the rib plate 30 can be independent structures, that is, the mounting beam 10 and the rib plate 30 can be separate structures, and the two can be manufactured independently.

[0159] In the above scheme, the mounting beam 10 and the rib plate 30 can be separate structures, and the two can be connected by simple processes (such as welding, riveting, threaded connection or other methods), which can effectively reduce the manufacturing difficulty and manufacturing cost of the bracket 100.

[0160] According to other embodiments of this application, please refer to Figure 4 , Figure 5 as well as Figure 10 , Figure 10 This is a top view of the bracket 100 in some other embodiments of this application.

[0161] The multiple mounting beams 10 include a first mounting beam 10a and a second mounting beam 10b located in the middle. The first mounting beam 10a is provided with multiple connecting parts 20 at intervals along the second direction y, and the second mounting beam 10b is provided with multiple connecting parts 20 at intervals along the second direction y. A channel 10c for the frame 200 to pass through is formed between the connecting parts 20 on the first mounting beam 10a and the connecting parts 20 on the second mounting beam 10b. The connecting parts 20 are used to connect with the longitudinal beams of the frame 200.

[0162] In some embodiments, the frame 200 may include a pair of longitudinal beams, such as a first longitudinal beam 201 and a second longitudinal beam 202, the first longitudinal beam 201 and the second longitudinal beam 202 being arranged at a lateral interval along the frame 200 and extending longitudinally along the frame 200.

[0163] The first mounting beam 10a can be set to correspond to the first longitudinal beam 201, and the second mounting beam 10b can be set to correspond to the second longitudinal beam 202. The mounting beams 10 can extend longitudinally along the frame 200, and multiple mounting beams 10 can be arranged at intervals laterally along the frame 200.

[0164] Please see Figure 4 and Figure 5The phrase "a plurality of connecting parts 20 are provided at intervals along the second direction y on the first mounting beam 10a" can be understood as meaning that, in the longitudinal direction of the frame 200, the first mounting beam 10a has multiple connecting parts 20, for example, the first mounting beam 10a has two, three, four, or other numbers of connections. These multiple connecting parts 20 can be used to connect with the first longitudinal beam 201. (See also...) Figure 4 and Figure 5 The phrase "a plurality of connecting parts 20 are provided at intervals along the second direction y on the second mounting beam 10b" can be understood as meaning that, in the longitudinal direction of the frame 200, the second mounting beam 10b is provided with a plurality of connecting parts 20, for example, the second mounting beam 10b has two, three, four, or other numbers of connections. These plurality of connecting parts 20 can be used to connect with the second longitudinal beam 202.

[0165] The “channel 10c” is composed of multiple connecting parts 20 on the first mounting beam 10a and multiple connecting parts 20 on the second mounting beam 10b. The channel 10c can extend along the longitudinal direction of the frame 200 so that the frame 200 can pass through.

[0166] The first mounting beam 10a and the second mounting beam 10b are the two middle mounting beams 10 among a plurality of mounting beams 10. That is, at least one mounting beam 10, such as one, two, or three, can be provided on the side of the first mounting beam 10a opposite to the second mounting beam 10b. Similarly, at least one mounting beam 10, such as one, two, or three, can be provided on the side of the second mounting beam 10b opposite to the first mounting beam 10a. In some embodiments, please refer to... Figure 5 There are four mounting beams 10, which are spaced laterally along the frame 200 to form three housing spaces 100a. That is, the batteries 2000 in the three housing spaces 100a are arranged laterally along the frame 200, and each battery 2000 can be arranged longitudinally along the frame 200.

[0167] In the above scheme, by providing multiple connecting parts 20 arranged at intervals along the second direction y on the first mounting beam 10a and multiple connecting parts 20 arranged at intervals along the second direction y on the second mounting beam 10b, and forming a channel 10c between the connecting parts 20 on the first mounting beam 10a and the connecting parts 20 on the second mounting beam 10b for the frame 200 to pass through, the first direction x can be defined as the lateral direction of the frame 200 (that is, the arrangement direction of a pair of longitudinal beams of the frame 200), thereby defining that the battery 2000 is arranged along the longitudinal direction of the frame 200 and multiple batteries 2000 are arranged along the lateral direction of the frame 200, providing more options for the layout of the battery 2000, and thus improving the compatibility of the bracket 100.

[0168] According to some embodiments of this application, please refer to Figure 5 and Figure 10 The bracket 100 also includes a first connecting beam 40, which extends along a first direction x and connects two adjacent mounting beams 10.

[0169] The first connecting beam 40 is a beam structure that can extend along a first direction x, for example, along the lateral direction of the frame 200. The first connecting beam 40 connects two adjacent mounting beams 10, and its function may include improving the structural stability of the two adjacent mounting beams 10. Its function may also include enabling the two adjacent mounting beams 10 to be integrated into a single unit.

[0170] In some embodiments, the first connecting beam 40 may be plate-shaped, column-shaped, or rod-shaped.

[0171] In some embodiments, the first connecting beam 40 can connect two adjacent mounting beams 10 by means of bonding, welding, riveting, or threading. In some embodiments, the first connecting beam 40 and the mounting beam 10 can be integrally formed.

[0172] In the above scheme, by setting the first connecting beam 40, the two adjacent mounting beams 10 are connected to each other, thereby improving the structural stability of the two adjacent mounting beams 10, effectively supporting the battery 2000, reducing the risk of the battery 2000 falling off, and improving the driving stability of the vehicle 10000.

[0173] According to some embodiments of this application, please refer to Figure 5 The bracket 100 also includes a rib plate 30, which is located on the side of the connecting part 20 away from the channel 10c. The rib plate 30 connects the connecting part 20 and the first connecting beam 40.

[0174] In some embodiments, the rib 30 may be a component connecting the connecting portion 20 and the first connecting beam 40. In some embodiments, the rib 30 may be a component for strengthening the structural strength of the connecting portion 20, the first connecting beam 40, and the frame 200. In some embodiments, the rib 30 may be a reinforcing rib, reinforcing beam, or reinforcing rib disposed between the connecting portion 20 and the first connecting beam 40. In some embodiments, the rib 30 may be made of materials such as aluminum alloy, steel, or cast iron. In some embodiments, the materials of the rib 30, the connecting portion 20, and the first connecting beam 40 may be the same or different.

[0175] In some embodiments, the rib 30 can be connected to the connecting portion 20 by welding, threaded connection, or other connection methods. Alternatively, in some embodiments, the rib 30 can be integrally formed with the connecting portion 20. In some embodiments, the rib 30 can be connected to the first connecting beam 40 by welding, threaded connection, or other connection methods. Alternatively, in some embodiments, the rib 30 can be integrally formed with both the connecting portion 20 and the first connecting beam 40.

[0176] In the above solution, by setting ribs 30 on the outside of the frame 200, the space on the outside of the frame 200 can be made reasonable, and the structural strength of the connecting part 20 and the first connecting beam 40 can be improved, thereby improving the structural strength of the mounting beam 10, reducing the risk of the battery 2000 falling off, and improving the driving reliability of the vehicle 10000 body.

[0177] According to some embodiments of this application, please refer to Figure 5 The connecting part 20 extends along the direction of gravity z.

[0178] In some embodiments, the gravity direction z is perpendicular to the longitudinal direction and the transverse direction of the frame 200.

[0179] "The connecting part 20 extends along the gravity direction z" can be understood as the connecting part 20 having a surface parallel to the gravity direction z, which can fit against the outer side of the longitudinal beam of the frame 200.

[0180] In the above scheme, by setting the connecting part 20 to extend along the gravity direction z, the connecting part 20 has a large area in the gravity direction z to connect with the longitudinal beam, thereby improving the connection stability between the mounting beam 10 and the longitudinal beam, reducing the risk of the battery 2000 falling off, and improving the driving reliability of the vehicle 10000 body.

[0181] According to some embodiments of this application, the connecting portion 20 is the flange of the rib plate 30, and the rib plate 30 and the connecting portion 20 are arranged perpendicular to each other.

[0182] The statement "the connecting part 20 is the flange of the rib 30" can be understood as the connecting part 20 being formed by bending the rib 30, which means that the connecting part 20 and the rib 30 are an integral structure. The statement "the rib 30 and the connecting part 20 are set perpendicular to each other" can be understood as the connecting part 20 being formed by bending the rib 30 at a 90-degree angle.

[0183] In the above scheme, the connecting part 20 can be the flange of the rib plate 30, that is, the connecting part 20 and the rib plate 30 are integrally formed, which can make the connecting part 20 and the rib plate 30 have high structural strength, effectively provide structural strength for the mounting beam 10, thereby effectively supporting the battery 2000 and reducing the risk of the battery 2000 falling off.

[0184] According to some embodiments of this application, please refer to Figure 9 The rib 30 includes a first rib 33 and a second rib 34 stacked together. The connecting part 20 includes a first sub-connecting part (not shown in the figure) and a second sub-connecting part (not shown in the figure). The first sub-connecting part is the flange of the first rib 33, and the second sub-connecting part is the flange of the second rib 34.

[0185] In some embodiments, the rib 30 can be a double-layer plate structure. For example, the rib 30 can be formed by stacking two plate-like structures. Or, the rib 30 can be formed into a two-layer plate structure by bending or other processes from a plate-like structure.

[0186] Please see Figure 9 In the thickness direction of the rib 30, the rib 30 has a first rib 33 and a second rib 34 that are stacked on top of each other.

[0187] The first sub-connecting part is a flange formed by bending the first rib 33, and the second sub-connecting part is a flange formed by bending the second rib 34. In the thickness direction of the rib 30, the first sub-connecting part and the second sub-connecting part are located on opposite sides of the rib 30.

[0188] In the above scheme, the rib plate 30 can be a double-layer plate structure. Since the rib plate 30 is a double-layer plate structure, the rib plate 30 can form two flanges facing opposite directions, that is, form the first sub-connection part and the second sub-connection part, so that the rib plate 30 and the longitudinal beam have a large connection area, improve the connection stability between the rib plate 30 and the longitudinal beam, thereby improving the structural strength of the mounting beam 10, so that the mounting beam 10 can effectively support the battery 2000 and reduce the risk of the battery 2000 falling off.

[0189] According to some embodiments of this application, please refer to Figure 4 The bracket 100 also includes a second connecting beam 50, which connects two adjacent connecting parts 20.

[0190] The second connecting beam 50 is a beam structure, and in some embodiments, the second connecting beam 50 may extend longitudinally along the frame 200. The second connecting beam 50 connects two adjacent connecting parts 20, and its function may include improving the structural stability of the two adjacent connecting parts 20. In some embodiments, the second connecting beam 50 may be plate-shaped, column-shaped, or rod-shaped.

[0191] In some embodiments, the second connecting beam 50 can connect two adjacent connecting portions 20 by means of bonding, welding, riveting, or threading. In some embodiments, the second connecting beam 50 and the connecting portion 20 can be integrally formed.

[0192] In the above solution, by setting a second connecting beam 50 to connect two adjacent connecting parts 20, the structural stability of the connecting part 20 can be improved, thereby improving the structural stability of the bracket 100, reducing the risk of the battery 2000 detaching, and improving the driving stability of the vehicle 10000.

[0193] According to other embodiments of this application, please refer to Figure 9 A reinforcing plate 60 is provided on the connecting part 20, and the reinforcing plate 60 is used to connect the frame 200.

[0194] In some embodiments, the reinforcing plate 60 can be used to strengthen the structural strength of the connecting portion 20 and improve the connection stability between the connecting portion 20 and the frame 200. In some embodiments, the reinforcing plate 60 can be a sheet-like structure, that is, the reinforcing plate 60 is relatively thin, and the reinforcing plate 60 can be attached to the surface of the connecting portion 20 and connected to the frame 200. In some embodiments, the reinforcing plate 60 can be connected to the frame 200 by welding, riveting, or threaded connection.

[0195] Please see Figure 9 The mounting unit may also include a reinforcing plate 60, which includes a first part 61, a second part 62, and a third part 63. The first part 61 is connected to the top surface of the longitudinal beam. The ends of the second part 62 and the third part 63 are connected to the first part 61. The second part 62 and the third part 63 are arranged opposite each other along the longitudinal direction of the frame 200, and a clearance gap is formed between the second part 62 and the third part 63. The clearance gap can avoid the rib 30 so that the second part 62 and the third part 63 can be located on opposite sides of the rib 30. The second part 62 can contact the part of the connecting portion 20, that is, the part of the connecting portion 20 is located between the second part and the frame 200. The third part 63 can contact the part of the connecting portion 20, that is, the part of the connecting portion 20 is located between the third part 63 and the frame 200. In some embodiments, the first part 61 is fixed to the top surface of the longitudinal beam of the frame 200 by a threaded part, the second part is connected to the outer side of the frame 200 by a threaded part passing through the connecting part 20, and the third part 63 is connected to the outer side of the frame 200 by a threaded part passing through the connecting part 20.

[0196] In the above solution, by setting the reinforcing plate 60, the structural strength of the connecting part 20 can be effectively improved, the connection stability between the connecting part 20 and the frame 200 can be improved, thereby improving the structural stability of the bracket 100, reducing the risk of the battery 2000 falling off, and improving the driving stability of the vehicle 10000.

[0197] According to some embodiments of this application, the mounting beam 10 is a square tube beam.

[0198] In some embodiments, the mounting beam 10 may be a tubular structure with an internal cavity.

[0199] In the above scheme, by setting the mounting beam 10 as a square tube beam, the material cost is low and the material structure has high strength, which can effectively support the battery 2000 and reduce the risk of the battery 2000 falling off.

[0200] According to some embodiments of this application, please refer to Figure 2 Two rows of mounting parts 11 are provided on the two middle mounting beams 10 of the multiple mounting beams 10, and these two rows of mounting parts 11 are staggered. Figure 2 In the middle, part of the mounting section 11 is obscured by the crossbeam of the frame 200.

[0201] The phrase "two rows of mounting parts 11 are provided on the two middle mounting beams 10 among multiple mounting beams 10" can be understood as meaning that the two middle mounting beams 10 can each be provided with two rows of mounting parts 11. One row of mounting parts 11 is a portion of a set of mounting parts 11, and the other row is a portion of a different set of mounting parts 11. The phrase "the two rows of mounting parts 11 are staggered" can be understood as meaning that the projections of the two rows of mounting parts 11 do not overlap along the first direction x.

[0202] The two mounting beams 10 located in the middle are provided with two rows of mounting parts 11, which can respectively mount two adjacent batteries 2000.

[0203] In the above scheme, during battery swapping, multiple battery swapping actuators (such as battery swapping bits) can simultaneously act on the parts where multiple mounting parts 11 are connected to the battery 2000. The two mounting beams 10 in the middle can mount two batteries 2000. By staggering the two rows of mounting parts 11 on the two mounting beams 10, the risk of interference between adjacent battery swapping actuators can be reduced, allowing multiple battery swapping actuators to work simultaneously and improving battery swapping efficiency.

[0204] According to some embodiments of this application, please refer to Figure 7 The mounting section 11 includes mounting holes 110 formed on the mounting beam 10.

[0205] In some embodiments, the mounting hole 110 can be a through-hole structure that penetrates the mounting beam 10 along the gravity direction z. In some embodiments, the battery 2000 has a mounting member that can pass through the mounting hole 110 and be mounted on the mounting beam 10.

[0206] In the above scheme, on the one hand, the mounting part 11 has a simple structure and is easy to manufacture; on the other hand, because the mounting part 11 has a simple structure, the connection method between the battery 2000 and the mounting part 11 is also simple, which can effectively improve the battery swapping efficiency.

[0207] According to other embodiments of this application, please refer to Figure 11 , Figure 11 This is a schematic diagram of the mounting part 11 in other embodiments of this application.

[0208] The mounting part 11 also includes a mounting sleeve 111, which is disposed in the mounting hole 110.

[0209] In some embodiments, the mounting sleeve 111 may be disposed within the mounting hole 110. The mounting sleeve 111 may be disposed within the mounting hole 110 by means of bonding, welding, threaded connection, or other methods. In some embodiments, the material of the mounting sleeve 111 may be the same as or different from the material of the mounting beam 10. In some embodiments, the material of the mounting sleeve 111 may be aluminum alloy, steel, or reinforced plastic, etc.

[0210] In the above solution, by setting a mounting sleeve 111 inside the mounting hole 110, the structural strength of the mounting part 11 can be improved, so that the battery 2000 can be stably connected to the bracket 100, reducing the risk of the battery 2000 falling off and improving the driving stability of the vehicle 10000.

[0211] According to some embodiments of this application, please refer to Figure 12 , Figure 12 This is a schematic diagram of a bracket assembly 1000 in some embodiments of this application. A bracket assembly 1000 is also provided, comprising a bracket 100 as described above and a plurality of first connectors 1001. The plurality of first connectors 1001 are disposed on the bracket 100, the number of first connectors 1001 being equal to the number of sets of mounting portions 11, and each first connector 1001 being used to connect to a second connector of a battery 2000.

[0212] The bracket assembly 1000 is a component for mounting and supporting the battery 2000. In the vehicle 10000, the bracket assembly 1000 may be disposed at the bottom of the vehicle 10000. In some embodiments, the bracket assembly 1000 may include a frame 200, or the bracket assembly 1000 may be mounted on the frame 200.

[0213] In some embodiments, the first connector 1001 is a component that connects to the second connector of the battery 2000, and one first connector 1001 is used to connect to the second connector of the battery 2000. In some embodiments, the first connector 1001 may include, but is not limited to, a high- or 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- or low-voltage connector may be electrically connected to the battery 2000 to realize the input or output of the battery 2000, and to realize the input or output of electrical signals. The liquid-cooling connector may be used for the input or output of the heat exchange medium of the battery 2000 to perform thermal management of the battery 2000.

[0214] The statement that "the number of first connectors 1001 is equal to the number of mounting sections 11" can be understood as meaning that the vehicle 10000 can swap batteries on demand. Regardless of the number of batteries 2000 mounted on the bracket assembly 1000 via the mounting section 11, each battery 2000 can connect to its corresponding first connector 1001, allowing each battery 2000 to function normally and charge / discharge properly. For example, based on the vehicle 10000's range requirements, it can be divided into short-distance range requirements, medium-distance range requirements, and long-distance range requirements. Short-distance range requirements correspond to one battery 2000; medium-distance range requirements correspond to two batteries 2000; and long-distance range requirements correspond to three batteries 2000. Therefore, the bracket 100 of the bracket assembly 1000 can be equipped with three sets of mounting sections 11 to accommodate up to three batteries 2000, meeting the longest range requirements. When short-distance range is required, only one battery 2000 can be mounted, and the second connector of the battery 2000 is connected to one first connector 1001. When medium-distance range is required, only two batteries 2000 can be mounted, and the second connectors of the two batteries 2000 are connected to the two first connectors 1001 respectively. When long-distance range is required, three batteries 2000 can be mounted, and the second connector of each battery 2000 is connected to the corresponding first connector 1001.

[0215] In the above solution, by setting multiple first connectors 1001 and multiple sets of mounting parts 11 on the bracket 100, the number of batteries 2000 that need to be replaced can be adjusted according to the range requirements (that is, battery replacement on demand; for example, when the required range is short, a smaller number of batteries 2000 can be installed on the corresponding number of mounting parts 11 in the multiple sets of mounting parts 11, and the second connector of each battery 2000 is connected to the corresponding first connector 1001; when the required range is long, a larger number of batteries 2000 can be installed on the corresponding number of mounting parts 11 in the multiple sets of mounting parts 11, and the second connector of each battery 2000 is connected to the corresponding first connector 1001), thereby saving the cost of additional batteries 2000 and effectively reducing the battery replacement cost.

[0216] According to some embodiments of this application, some embodiments of this application also provide a vehicle 10000, including the bracket assembly 1000 described above and at least one battery 2000. Each battery 2000 is detachably connected to a set of mounting parts 11.

[0217] In the above solution, a vehicle 10000 is provided. By setting the bracket assembly 1000 provided above, the vehicle 10000 can swap batteries on demand. That is, according to its own range requirements, the number of swap batteries 2000 can be adjusted to reduce the cost of battery swapping.

[0218] According to some embodiments of this application, a bracket 100 is provided; please refer to [the relevant documentation]. Figures 1-11 .

[0219] The bracket 100 is used for mounting on the frame 200 of vehicle 10000, specifically the frame 200 of a heavy-duty truck. The bracket 100 can be installed on the frame 200 of vehicle 10000 at the time of manufacture. Alternatively, the bracket 100 can be added to the frame 200 of vehicle 10000 after it has left the factory.

[0220] In some embodiments, the frame 200 can be a heavy-duty truck frame 200. The required battery 2000 capacity varies depending on the type of cargo being transported or the transport route. For example, a 200 kWh battery 2000 (e.g., one battery 2000) is needed for short-distance range, a 400 kWh battery 2000 (e.g., two batteries 2000) is needed for medium-distance range, and a 600 kWh battery 2000 (e.g., three batteries 2000) is needed for long-distance range. To save on battery swapping costs, the bracket 100 is provided with multiple sets of mounting parts 11, each set of mounting parts 11 for detachably connecting one battery 2000.

[0221] The bracket 100 includes multiple mounting beams 10, for example, four mounting beams 10, which are spaced apart in a first direction x to divide the space into three receiving spaces 100a. Each receiving space 100a is used to accommodate one battery 2000. That is, by installing the bracket 100, three batteries 2000 can be mounted, or at least one battery 2000 can be mounted. In other words, a vehicle 10000 equipped with the bracket 100 can swap one to three batteries 2000.

[0222] Multiple mounting parts 11 can be installed on each mounting beam 10, for example, see Figure 2 Along the first direction x, the two outermost mounting beams 10 are each provided with a row of mounting parts 11, each mounting part 11 having 6 mounting parts 11. The 6 mounting parts 11 in each row can be arranged along the second direction y. The second direction y, the first direction x, and the gravity direction z are perpendicular to each other. The two middle mounting beams 10 are each provided with two rows of mounting parts 11, that is, 12 mounting parts 11 in total (in... Figure 2(The middle section of the mounting portion 11 is obscured by the crossbeam of the frame 200). In the first direction x, every two rows of mounting portions 11 form a group of mounting portions 11, meaning that a battery 2000 can be mounted on the bracket 100 through 12 mounting portions 11. The mounting portions 11 in the two middle rows of mounting beams 10 are staggered, which reduces the risk of interference between adjacent battery swapping actuators, allowing multiple battery swapping actuators to operate simultaneously and improving battery swapping efficiency. In some embodiments, the mounting portion 11 may include mounting holes 110 formed on the mounting beam 10 and mounting sleeves 111 disposed within the mounting holes 110.

[0223] The frame 200 includes a pair of longitudinal beams, namely a first longitudinal beam 201 and a second longitudinal beam 202. The transverse direction of the frame 200 can be the arrangement direction of the first longitudinal beam 201 and the second longitudinal beam 202. The longitudinal direction of the frame 200 can be the extension direction of the first longitudinal beam 201 and the second longitudinal beam 202.

[0224] In some embodiments, see Figure 3 The first direction x can be the longitudinal direction of the frame 200, that is, the multiple batteries 2000 are arranged along the longitudinal direction of the frame 200. Multiple mounting beams 10 are spaced apart along the longitudinal direction of the frame 200. Each mounting beam 10 is provided with two connecting parts 20, which are spaced apart along the transverse direction of the frame 200. The two connecting parts 20 and the mounting beam together form an upward-opening groove 21 for the frame 200 to pass through.

[0225] A rib plate 30 is also provided between the connecting part 20 and the hanging beam 10. The rib plate 30 is used to strengthen the structural strength of the connecting part 20 and the hanging beam 10.

[0226] In some embodiments, see Figure 4 and Figure 5 The first direction x can be the lateral direction of the frame 200, that is, multiple batteries 2000 are arranged along the lateral direction of the frame 200. Multiple mounting beams 10 are spaced apart along the lateral direction of the frame 200.

[0227] The four mounting beams 10 include a first mounting beam 10a and a second mounting beam 10b located in the middle. The first mounting beam 10a has a plurality of connecting parts 20 spaced apart along the longitudinal direction of the frame 200. The second mounting beam 10b has a plurality of connecting parts 20 spaced apart along the longitudinal direction of the frame 200. A channel 10c for the frame 200 to pass through is formed between the connecting parts 20 on the first mounting beam 10a and the connecting parts 20 on the second mounting beam 10b. The connecting parts 20 are used to connect with the longitudinal beams of the frame 200.

[0228] In the transverse direction of the frame 200, a plurality of first connecting beams 40 are provided between two adjacent mounting beams 10, and the first connecting beams 40 connect the two adjacent mounting beams 10. On the outer side of the frame 200, a rib plate 30 is provided between the first connecting beams 40 and the connecting part 20, and the rib plate 30 is used to strengthen the structural strength of the connecting part 20 and the first connecting beams 40.

[0229] In some embodiments, a second connecting beam 50 may be provided between two adjacent connecting portions 20 along the longitudinal direction of the frame 200.

[0230] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
