Electric vehicles have become an important part of the sustainable development of the automobile industry due to their advantages of energy conservation and environmental protection.

[0082] At present, from the perspective of market development, the application of power batteries is becoming more and more extensive. Power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0083] In the battery production process, batteries are usually transported between various production equipment by pallets in conjunction with conveyor lines. Pallets are usually used to transport battery modules and battery cells in battery modules. Side plate limiters and end plate limiters are usually set on the pallet, and the side plate limiters and end plate limiters are used to limit the displacement of the battery module on the pallet to fix the battery module and improve the stability of the pallet in conveying the battery module.

[0084] Current battery production lines are usually capable of producing battery modules or battery cells of various specifications and sizes. However, the side plate limiters and end plate limiters on current pallets are mostly directly fixed on the pallets. This results in the need to prepare pallets of various specifications during the battery production process, which easily causes the pallets to be idle, and the process of replacing pallets is also relatively cumbersome.

[0085] Based on the above considerations, in order to alleviate the problem of poor tray compatibility, some embodiments of the present application provide a battery restraint device, in which a movable first limit component and a second limit component are arranged on the tray, and the first limit component and the second limit component are enabled to move in different directions to limit the displacement of the battery module from different directions.

[0086] In such a battery restraint device, the first limit assembly and the second limit assembly can limit the displacement of the battery module in different directions, so that the battery module can be placed on the battery restraint device more stably, thereby improving the stability of the battery restraint device in transporting the battery module and reducing the shaking of the battery module on the battery restraint device; the movable first limit assembly and the second limit assembly can also adapt to battery modules of different sizes, thereby improving the compatibility of the battery restraint device.

[0087] In addition to being able to carry battery modules, the battery restraint device 100 disclosed in the embodiments of the present application can also carry battery cells or other workpieces. For the convenience of explanation, the following embodiments will be described using the battery restraint device 100 provided in some embodiments of the present application for carrying battery modules as an example.

[0088] In a first aspect, some embodiments of the present application provide a battery restraint device 100, referring to Figures 1 to 4 , Figure 1The direction of the X-axis is the second direction, which is also the length direction of the battery restraint device 100; the direction of the Y-axis is the first direction, which is also the width direction of the battery restraint device 100; the direction of the Z-axis is the height direction of the battery restraint device 100.

[0089] Some embodiments of the present application provide a battery restraint device 100 including a tray 10, a first limiting assembly 20 and a second limiting assembly 30, wherein the first limiting assembly 20 is movably disposed on the tray 10 along a first direction, and the first limiting assembly 20 can be fixed to the tray 10; the second limiting assembly 30 is movably disposed on the tray 10 along a second direction, and the second limiting assembly 30 can be fixed to the tray 10; the first direction and the second direction are arranged at an angle.

[0090] The tray 10 refers to a structure in the battery restraint device 100 that is used to provide a fixed foundation for other structures. For example, the first limit assembly 20 and the second limit assembly 30 can be connected to the tray 10, and the tray 10 can also play a role in carrying the battery module; the tray 10 is usually a thin plate structure to reduce weight and space occupancy. The tray 10 can also be a block structure, a columnar structure or a structure of other shapes; the shape of the tray 10 can be square, round or other regular shapes, and can also be set to an irregular shape according to transportation, processing and other requirements; the material of the tray 10 can include metal, plastic or other materials.

[0091] The first limiting assembly 20 refers to a structure in the battery restraint device 100 for limiting the displacement of the battery module on the tray 10, that is, after the battery module is placed on the battery restraint device 100, the battery module can abut against the first limiting assembly 20 or there is a small gap between the battery module and the first limiting assembly 20 to reduce the displacement of the battery module in the direction of the first limiting assembly 20; the first limiting assembly 20 may include a guard plate, a limiting block or other structures to limit the displacement of the battery module; the first limiting assembly 20 may include only one structural member 82 for abutting against the battery module, and may also include other structural members 82.

[0092] The first limiting assembly 20 is movably disposed on the tray 10 along the first direction, that is, the first limiting assembly 20 can move relative to the tray 10 along the first direction, and the first limiting assembly 20 can abut against the battery module or the corresponding side of the battery module along the first direction.

[0093] The first position-limiting assembly 20 may be movably connected to the tray 10 through a slide groove, a slide rail, a guide shaft or other structures. For example, the tray 10 may be provided with a guide groove extending along the first direction, and part of the first position-limiting assembly 20 may be placed in the guide groove and slide along the guide groove; for example, the tray 10 may also be provided with a guide shaft extending along the first direction, and the guide shaft passes through the first position-limiting assembly 20, and the first position-limiting assembly 20 may slide along the guide shaft.

[0094] The first position-limiting component 20 can also be fixed to the tray 10, and the first position-limiting component 20 can be fixed to the tray 10 in a variety of ways. For example, the first position-limiting component 20 can be made to have an interference fit with the tray 10, so as to fix the first position-limiting component 20 by the friction between the first position-limiting component 20 and the tray 10; for another example, a plurality of holes at different positions can be opened on the tray 10, and a latch can be set on the first position-limiting component 20, and after the first position-limiting component 20 moves, the latch can be inserted into the corresponding hole to fix the first position-limiting component 20; it can be understood that the first position-limiting component 20 can also be fixed to the tray 10 in other ways, not limited to the above two ways.

[0095] The number of the first limit assembly 20 can be one, or two or more. For example, when there is only one first limit assembly 20, the first limit assembly 20 can cooperate with the second limit assembly 30 to limit the displacement of the battery module in two directions, and at this time, the two adjacent faces of the battery module can be respectively against the first limit assembly 20 and the second limit assembly 30; when there are two first limit assemblies 20, the two first limit assemblies 20 can be arranged relative to each other, and at this time, the two opposite faces of the battery module can be respectively opposite to the two first limit assembly assemblies; it can be understood that the number of the first limit assembly 20 can also be three or more, and multiple first limit assemblies 20 can also be arranged in other ways, not limited to the above two.

[0096] Similar to the first limiting component 20, the second limiting component 30 refers to a structure in the battery restraint device 100 for limiting the displacement of the battery module on the tray 10, that is, after the battery module is placed on the battery restraint device 100, the battery module can abut against the second limiting component 30 or there is a small gap between the battery module and the second limiting component 30 to reduce the displacement of the battery module in the direction of the second limiting component 30; the second limiting component 30 may include a guard plate, a limiting block or other structures to limit the displacement of the battery module; the second limiting component 30 may include only one structural member 82 for abutting against the battery module, and may also include other structural members 82.

[0097] The second limiting assembly 30 is movably disposed on the tray 10 along the second direction, that is, the second limiting assembly 30 can move relative to the tray 10 along the second direction, and the second limiting assembly 30 can abut against the battery module or the corresponding side of the battery module along the second direction.

[0098] The second position-limiting assembly 30 may be movably connected to the tray 10 through a slide groove, a slide rail, a guide shaft or other structures. For example, the tray 10 may be provided with a guide groove extending along the second direction, and part of the second position-limiting assembly 30 may be placed in the guide groove and slide along the guide groove; for example, the tray 10 may also be provided with a guide shaft extending along the second direction, and the guide shaft passes through the second position-limiting assembly 30, and the second position-limiting assembly 30 may slide along the guide shaft.

[0099] The second position-limiting component 30 can also be fixed to the tray 10, and the second position-limiting component 30 can be fixed to the tray 10 in a variety of ways. For example, the second position-limiting component 30 can be made to have an interference fit with the tray 10, so as to fix the second position-limiting component 30 by the friction between the second position-limiting component 30 and the tray 10; for another example, a plurality of holes at different positions can be opened on the tray 10, and a latch can be set on the second position-limiting component 30, and after the second position-limiting component 30 moves, the latch can be inserted into the corresponding hole to fix the second position-limiting component 30; it can be understood that the second position-limiting component 30 can also be fixed to the tray 10 in other ways, not limited to the above two ways.

[0100] The number of the second limit assembly 30 can be one, or two or more. For example, when there is only one second limit assembly 30, the second limit assembly 30 can cooperate with the second limit assembly 30 to limit the displacement of the battery module in two directions, and at this time, the two adjacent faces of the battery module can be respectively against the second limit assembly 30 and the second limit assembly 30; when there are two second limit assemblies 30, the two second limit assemblies 30 can be arranged relative to each other, and at this time, the two relative faces of the battery module can be respectively opposite to the two second limit assembly assemblies; it can be understood that the number of the second limit assembly 30 can also be three or more, and multiple second limit assemblies 30 can also be arranged in other ways, not limited to the above two methods.

[0101] The first direction and the second direction refer to the movement directions of the first limiting assembly 20 and the second limiting assembly 30 on the tray 10, respectively. For example, the first direction is Figure 1 The direction of the Y axis, the second direction is Figure 1 The direction where the X-axis is located, the first direction and the second direction may be parallel to the length direction and the width direction of the tray 10 respectively, or may be other directions.

[0102] The first direction and the second direction are arranged at an angle, that is, the first direction and the second direction are different and staggered, and the angle between the first direction and the second direction can be 90° or other angles; this arrangement enables the first limit assembly 20 and the second limit assembly 30 to be opposite to different surfaces of the battery module from different directions to limit the displacement of the battery module in different directions.

[0103] When the size of the battery module that the battery restraint device 100 needs to carry changes, the first limit assembly 20 and the second limit assembly 30 can be moved relative to the tray 10 to change the position of the first limit assembly 20 and the second limit assembly 30, and the first limit assembly 20 and the second limit assembly 30 can be fixed after they move to the desired position.

[0104] In this embodiment, a movable first limit assembly 20 and a second limit assembly 30 are provided on the tray 10, and the first limit assembly 20 and the second limit assembly 30 can be respectively movable in different directions, and at the same time, the first limit assembly 20 and the second limit assembly 30 can be fixed to the tray 10 after the movement, so that the first limit assembly 20 and the second limit assembly 30 can limit the displacement of the battery module in different directions, so that the battery module can be placed on the battery restraint device 100 more stably; and the movable first limit assembly 20 and the second limit assembly 30 can also adapt to battery modules of different sizes, so as to improve the compatibility of the battery restraint device 100.

[0105] According to some embodiments of the present application, reference Figure 1 , Figure 2 , Figure 5 The battery restraint device 100 also includes a first fixing component 40 and a second fixing component 50 arranged on the tray 10; the first limiting component 20 can be fixed at different positions of the first fixing component 40 to be fixed at different positions of the tray 10; the second limiting component 30 can be fixed at different positions of the second fixing component 50 to be fixed at different positions of the tray 10.

[0106] The first fixing component 40 refers to a structure in the battery restraint device 100 for limiting the position of the first limiting component 20 , that is, after the first limiting component 20 moves and changes position, the first fixing component 40 can fix the first limiting component 20 at its position.

[0107] The first fixing component 40 can fix the first limiting component 20 in a variety of ways, so that the first limiting component 20 can be fixed at different positions of the first fixing component 40. In some embodiments, the first fixing component 40 may include a plurality of buckles at different positions. After the first limiting component 20 moves, the buckle can be clamped on the first limiting component 20 and fix the first limiting component 20, that is, at this time, the first limiting component 20 can be fixed on the buckles at different positions; in other embodiments, the first fixing component 40 may also include a friction strip abutting against the first limiting component 20. After the first limiting component 20 moves, the first limiting component 20 can be fixed by the friction between the friction strip, and at this time, the first limiting component 20 can also be fixed at different positions of the first fixing component 40; it can be understood that the first fixing component 40 may also include other structures to play the role of fixing the first limiting component 20, and is not limited to the above two structures.

[0108] The second fixing component 50 refers to a structure in the battery restraint device 100 for limiting the position of the second limiting component 30 , that is, after the second limiting component 30 moves and changes position, the second fixing component 50 can fix the second limiting component 30 at its position.

[0109] The second fixing component 50 can fix the second limiting component 30 in a variety of ways, so that the second limiting component 30 can be fixed at different positions of the second fixing component 50. In some embodiments, the second fixing component 50 may include a plurality of buckles at different positions. After the second limiting component 30 moves, the buckle can be clamped on the second limiting component 30 and fix the second limiting component 30, that is, at this time, the second limiting component 30 can be fixed on the buckles at different positions; in other embodiments, the second fixing component 50 may also include a friction strip abutting against the second limiting component 30. After the second limiting component 30 moves, the second limiting component 30 can be fixed by the friction force between the friction strip, and at this time, the second limiting component 30 can also be fixed at different positions of the second fixing component 50; it can be understood that the second fixing component 50 may also include other structures to play the role of fixing the second limiting component 30, and is not limited to the above two structures.

[0110] When the size of the battery module that the battery restraint device 100 needs to carry changes, the first limiting component 20 and the second limiting component 30 are moved relative to the tray 10, and the first limiting component 20 is fixed to the first fixing component 40 after it moves to the desired position, and the second limiting component 30 is fixed to the second fixing component 50 after it moves to the desired position.

[0111] In this embodiment, the battery restraint device 100 includes a first fixing component 40 and a second fixing component 50, so that the first limiting component 20 and the second limiting component 30 can be respectively fixed at different positions of the first fixing component 40 and the second fixing component 50 after being moved, thereby making the first limiting component 20 and the second limiting component 30 able to be fixed relative to the tray 10, so that the first limiting component 20 and the second limiting component 30 can be moved to adapt to battery modules of different sizes, and can also be fixed relative to the tray 10 to limit the displacement of the battery module.

[0112] refer to Figure 1 , Figure 5 In some embodiments, the first fixing component 40 includes a first base 41 connected to the tray 10, and at least two first connecting structures 42 are provided on the first base 41 along the first direction (Y); the first limiting component 20 includes a first connecting member 22, and the first connecting member 22 is used to be connected to any first connecting structure 42 to fix the first limiting component 20.

[0113] The first base 41 refers to a structure in the first fixing assembly 40 for providing a fixed foundation for other structures. The first base 41 may be rectangular, cylindrical or in other shapes. The material of the first base 41 may include plastic, metal or in other shapes. The first base 41 is connected to the pallet 10. The first base 41 may be fixedly connected to the pallet 10 by welding, gluing or the like. The first base 41 may also be detachably connected to the pallet 10 by bolt connection, snap connection or the like.

[0114] The first connection structure 42 refers to a structure formed on the first base 41, and the first connection member 22 refers to a structure in the first position-limiting component 20 for connecting with the first connection structure 42. For example, the first connection structure 42 can be a socket, and the first connection member 22 can be a latch, in which case the latch can be inserted into different sockets to fix the first position-limiting component 20 at different positions; the first connection structure 42 can also be a card body, and the first connection member 22 is a buckle, and the buckle can be clamped on different card bodies to fix the first position-limiting component 20 at different positions; the first connection structure 42 can also be a nylon velvet belt, and the first connection member 22 is a nylon hook belt, and the nylon hook belt can be connected to different positions of the nylon velvet belt to fix the first position-limiting component 20 at different positions; it can be understood that the first connection structure 42 and the first connection member 22 can also be other structures that can cooperate with each other, and are not limited to the above-mentioned structures.

[0115] The first connecting structures 42 are arranged on the base at intervals along the first direction (X). Since the first limiting assembly 20 moves along the first direction (X), the arrangement of the first connecting structure 42 along the first direction (X) can facilitate the cooperation between the first connecting member 22 and the first connecting structure 42. Since the processing of battery modules usually has standard requirements, and their specifications are usually fixed, the intervals of the first connecting structures 42 can be determined according to the different sizes of the battery modules, so that different positions of the first limiting assembly 20 can correspond to battery modules of different specifications, so that when the first connecting member 22 is connected to different first connecting structures 42, the first limiting assembly 20 can limit the displacement of battery modules of different specifications.

[0116] The number of the first connection structures 42 may be two, or three or more. The specific number of the first connection structures 42 is positively correlated with the number of specifications of the battery modules to be carried by the battery restraint device 100, so that the battery restraint device 100 can carry battery modules of different specifications.

[0117] At present, there are some pallets with movable side plate limiters and end plate limiters, but the side plate limiters and end plate limiters in such pallets are mostly fixed by bolts. Adjusting the position of the side plate limiters and end plate limiters requires the removal and installation of a large number of screws, which requires tools and is a cumbersome process. At present, there are also some pallets that use cylinders and electric cylinders to adjust the position of the side plate limiters and end plate limiters. Such battery restraint devices 100 also need to be equipped with a drive and control system for the cylinders and electric cylinders, which are heavy, complex in structure, and expensive.

[0118] In this embodiment, the first connecting structures 42 are arranged at intervals on the first base 41, so that the first limiting assembly 20 can be connected to different first connecting structures 42 through the first connecting member 22 after being moved, and the first limiting assembly 20 can be fixed to different positions of the tray 10 through the first connecting member 22 and the first connecting structure 42, thereby facilitating the first limiting assembly 20 to adapt to battery modules of different sizes and to limit the displacement of battery modules of different sizes on the tray 10.

[0119] In some embodiments, the first connection structure 42 is a socket, and the first connection member 22 is a pin, which can be inserted into the socket and also pulled out from the socket.

[0120] refer to Figure 1 , Figure 5 In some embodiments, the second fixing component 50 includes a second base 51 connected to the tray 10, and at least two second connecting structures 52 are provided on the second base 51 along the second direction (X); the second limiting component 30 includes a second connecting member 32, and the second connecting member 32 is used to be connected to any second connecting structure 52 to fix the second limiting component 30.

[0121] The second base 51 refers to a structure in the second fixing assembly 50 that is used to provide a fixed foundation for other structures. The second base 51 may be in a rectangular, cylindrical, or other shape. The material of the second base 51 may include plastic, metal, or other shapes. The second base 51 is connected to the pallet 10. The second base 51 may be fixedly connected to the pallet 10 by welding, gluing, or the like. The second base 51 may also be detachably connected to the pallet 10 by bolt connection, snap connection, or the like.

[0122] The second connection structure 52 refers to a structure formed on the second base 51, and the second connection member 32 refers to a structure in the second position-limiting assembly 30 for connecting with the second connection structure 52. For example, the second connection structure 52 may be a socket, and the second connection member 32 may be a latch, in which case the latch can be inserted into different sockets to fix the second position-limiting assembly 30 at different positions; the second connection structure 52 may also be a card body, and the second connection member 32 may be a buckle, and the buckle may be clamped on different card bodies to fix the second position-limiting assembly 30 at different positions; the second connection structure 52 may also be a nylon velvet belt, and the second connection member 32 may be a nylon hook belt, and the nylon hook belt may be connected to different positions of the nylon velvet belt to fix the second position-limiting assembly 30 at different positions; it is understandable that the second connection structure 52 and the second connection member 32 may also be other structures that can cooperate with each other, and are not limited to the above-mentioned structures.

[0123] The second connecting structures 52 are arranged on the base at intervals along the second direction (X). Since the second limiting assembly 30 moves along the second direction (X), the arrangement of the second connecting structure 52 along the second direction (X) can facilitate the cooperation between the second connecting member 32 and the second connecting structure 52. Since the processing of battery modules usually has specification requirements, and their specifications are usually fixed, the intervals of the second connecting structures 52 can be determined according to the different sizes of the battery modules, so that different positions of the second limiting assembly 30 can correspond to battery modules of different specifications, so that when the second connecting member 32 is connected to different second connecting structures 52, the second limiting assembly 30 can limit the displacement of battery modules of different specifications.

[0124] The number of the second connection structures 52 can be two, or three or more. The specific number of the second connection structures 52 is positively correlated with the number of specifications of the battery modules to be carried by the battery restraint device 100, so that the battery restraint device 100 can carry battery modules of different specifications.

[0125] In this embodiment, the second connecting structures 52 are arranged at intervals on the second base 51, so that the second limiting assembly 30 can be connected to different second connecting structures 52 through the second connecting member 32 after being moved, and the second limiting assembly 30 can be fixed at different positions of the tray 10 through the second connecting member 32 and the second connecting structure 52, thereby facilitating the second limiting assembly 30 to adapt to battery modules of different sizes and to limit the displacement of battery modules of different sizes on the tray 10.

[0126] In some embodiments, the second connection structure 52 is a socket, and the second connection member 32 is a plug, which can be inserted into the socket and pulled out from the socket.

[0127] According to some embodiments of the present application, reference Figures 1 to 4 The battery restraint device 100 also includes a third limiting member 60 arranged on the tray 10, and the third limiting member 60 is spaced apart from the second limiting assembly 30 along the second direction (X). The third limiting member 60 is used to abut against the battery module along the second direction (X) and clamp the workpiece together with the second limiting assembly 30.

[0128] The third limiter 60 refers to a structure in the battery restraint device 100 for limiting the displacement of the battery module on the tray 10, that is, after the battery module is placed on the battery restraint device 100, the battery module can abut against the third limiter 60 or there is a small gap between the battery module and the third limiter 60 to reduce the displacement of the battery module in the direction of the third limiter 60; the third limiter 60 is a guard plate, a limiter block or other structure to limit the displacement of the battery module; the material of the third limiter 60 may include metal, plastic or other materials.

[0129] The third limiting member 60 is spaced apart from the second limiting member 30 along the second direction (X), that is, the battery module can be placed between the second limiting member 30 and the third limiting member 60, so that the third limiting member 60 can abut against the battery module along the second direction; it also enables the second limiting member 30 to approach or move away from the third limiting member 60 to adjust the distance between the second limiting member 30 and the third limiting member 60, thereby facilitating the limitation of the displacement of battery modules of different sizes on the battery restraint device 100.

[0130] The provision of the third limiting member 60 enables the staff to adjust the size of the battery module that the battery restraint device 100 can accommodate in the second direction by only adjusting the position of the second limiting component 30, thereby simplifying the adjustment process of the battery restraint device 100 and improving the use efficiency.

[0131] When the second direction (X) is parallel to the length direction of the tray 10, the battery restraint device 100 moves along the second direction and transports the battery module. At this time, the battery module does not need to be in the central position of the battery restraint device 100 in the second direction. This arrangement simplifies the adjustment process of the battery restraint device 100 while reducing the possible negative impact on the battery restraint device 100.

[0132] In this embodiment, a third limit member 60 is provided, and the third limit member 60 is spaced apart from the second limit member 30 so that the battery module can be placed at the interval, thereby enabling the second limit member 30 and the third limit member 60 to respectively limit the displacement of the battery module along the second direction on both sides of the battery module assembly, so as to better limit the displacement of the battery module; at the same time, this arrangement also enables the battery restraint device 100 to adapt to battery module assemblies of different sizes by only adjusting one second limit member 30 in the second direction, thereby simplifying the adjustment process of the battery restraint device 100 and improving its use efficiency.

[0133] refer to Figure 1 , Figure 2 In some embodiments, there are two first limiting components 20, and the two first limiting components 20 are spaced apart along the first direction.

[0134] The two first limiting components 20 are arranged at intervals along the first direction, so that the battery module can be placed between the two first limiting components 20, so that the two first limiting components 20 can be respectively opposite to the two surfaces of the battery module, thereby better limiting the displacement of the battery module relative to the tray 10 in the first direction.

[0135] When the first direction is parallel to the width direction of the tray 10, the battery restraint device 100 moves along its length direction and transports the battery module. At this time, the adjustment distances of the two first limiting assemblies 20 should be the same so that the battery module can always be in the central position of the battery restraint device 100 in the first direction, so that each device can process the battery module.

[0136] In this embodiment, there are two first limiting components 20 and they are spaced apart so that the battery module can be placed between the two first limiting components 20, thereby enabling the two first limiting components 20 to limit the displacement of the battery module in the first direction on both sides of the battery module, respectively, so as to better limit the displacement of the battery module.

[0137] According to some embodiments of the present application, reference Figures 1 to 4 The battery restraint device 100 further includes a support assembly 70, and the support assembly 70 is used to support the battery module.

[0138] The support assembly 70 refers to the structure for supporting the battery module in the battery restraint device 100, that is, the support assembly 70 can be in contact with the bottom surface of the battery module so that the battery module is spaced apart from the tray 10, so that the battery module is suspended relative to the tray 10; the support assembly 70 may include only one component for supporting the battery module, or may include two or more components for supporting the battery module.

[0139] The support assembly 70 can be fixedly connected to the tray 10. For example, the support assembly 70 can be opposite to the bottom surface of the smallest battery module that the battery restraint device 100 can carry, so as to reduce the negative impact that the support assembly 70 may have on the activities of the first limiting assembly 20 and the second limiting assembly 30. Because the battery restraint device 100 is provided with the first limiting assembly 20, the second limiting assembly 30 and the third limiting member 60, when the support assembly 70 carries other larger battery modules, it can also support the battery module more stably under the action of the first limiting assembly 20, the second limiting assembly 30 and the third limiting member 60, and reduce the skewness of the battery module.

[0140] The support assembly 70 can also be movably connected to the tray 10 to support battery modules of different sizes. For example, the movable connection of the support assembly 70 can be achieved through structures such as slide grooves, slide rails, and guide shafts. The support assembly 70 can also be connected to the first limit assembly 20 or the second limit assembly 30 to facilitate operation by staff and simplify the adjustment process.

[0141] In this embodiment, the battery restraint device 100 also includes a support assembly 70, which supports the bottom surface of the battery module through the support assembly 70, thereby reducing the coverage of the bottom surface of the battery module by the battery restraint device 100, and facilitating better cleaning of the bottom surface of the battery module; at the same time, it can also reduce the contact area between the bottom surface of the battery module and the battery restraint device 100, thereby reducing the wear on the bottom surface of the battery module during placement, grasping, etc.

[0142] refer to Figure 1 , Figure 2 In some embodiments, the support assembly 70 includes a first support member 71 and a second support member 72 , the second support member 72 is connected to the second limiting assembly 30 ; the first support member 71 is connected to the tray 10 , or the first support member 71 is connected to the first limiting assembly 20 .

[0143] The first support member 71 and the second support member 72 are both structures in the support assembly 70 for supporting the battery module. The first support member 71 and the second support member 72 are respectively used to support different positions of the battery module.

[0144] The first support member 71 may be cylindrical, prismatic or other shapes, and the contact area between the first support member 71 and the battery module may be rectangular, circular, linear or other shapes; the material of the first support member 71 may include metal, plastic or other materials; the number of first support members 71 may be one, or two or more.

[0145] Similar to the first support member 71, the second support member 72 may be cylindrical, prismatic or other shapes, and the contact area between the second support member 72 and the battery module may be rectangular, circular, linear or other shapes; the material of the second support member 72 may include metal, plastic or other materials; the number of second support members 72 may be one, or two or more.

[0146] The second support member 72 is connected to the second limiting assembly 30, that is, the second support member 72 can move with the second limiting assembly 30. Since the second limiting assembly 30 can abut against the side of the battery module, the position where the second support member 72 contacts the bottom surface of the battery module can be close to the edge of the bottom surface of the battery module, so that the second support member 72 can support the battery module more stably, thereby reducing the shaking of the battery module.

[0147] The first support member 71 can be connected to the tray 10, and the first support member 71 is fixed relative to the tray 10. For example, the first support member 71 can be opposite to the bottom surface of the smallest battery module that the battery restraint device 100 can carry, so as to reduce the negative impact that the first support member 71 may have on the activities of the first limiting component 20 and the second limiting component 30. Because the battery restraint device 100 is provided with the first limiting component 20, the second limiting component 30 and the third limiting member 60, the first support member 71 can also support the battery module more stably under the action of the first limiting component 20, the second limiting component 30 and the third limiting member 60 when carrying other larger battery modules, and reduce the skewness of the battery module.

[0148] The first support member 71 can also be connected to the first limiting assembly 20, that is, the first support member 71 can move with the first limiting assembly 20. Since the first limiting assembly 20 can abut against the side of the battery module, the position where the first support member 71 contacts the bottom surface of the battery module can be close to the edge of the bottom surface of the battery module, so that the first support member 71 can support the battery module more stably, thereby reducing the shaking of the battery module.

[0149] In this embodiment, the second support member 72 is connected to the second limiting assembly 30, so that the second support member 72 can move with the second limiting assembly 30, so that the second support member 72 can support battery modules of different sizes; because the second support member 72 can move with the second limiting assembly 30, the first support member 71 is connected to the tray 10 and can also cooperate with the second limiting assembly 30 to support battery modules of different sizes, and at the same time can also reduce the overall weight of the first limiting assembly 20, which is convenient for adjustment of the first limiting assembly 20; the first support member 71 is connected to the first limiting assembly 20, so that the first support member 71 can also move with the first limiting assembly 20, so that the first support member 71 can support battery modules of different sizes.

[0150] refer to Figure 2 In some embodiments, in the second direction, the sizes of the first support member 71 and the second support member 72 are both smaller than the size of the tray 10 , and the first support member 71 is disposed on one side of the third limiting member 60 .

[0151] The length of the second support member 72 in the second direction (X) is the length of the second support member 72 in the direction of movement of the second limit member 30. Since the second support member 72 is used to support the battery module, and the battery module should be between the second limit member 30 and the third limit member 60, making the length of the second support member 72 smaller than the size of the tray 10 can reduce the negative impact that the second support member 72 may have on the movement of the second limit member 30, and can also reduce the possibility that the second support member 72 extends outside the tray 10 when the second limit member 30 approaches the third limit member 60.

[0152] The length of the first support member 71 in the second direction (X) is the length of the first support member 71 in the moving direction of the second limiting assembly 30, so that the length of the first support member 71 in the second direction (X) is smaller than the size of the tray 10, and the first support member 71 is arranged on one side of the third limiting member 60, so as to leave a certain space at the position where the second limiting assembly 30 moves, so as to reduce the negative impact that the first support member 71 may have on the movement of the second limiting assembly 30; at the same time, in the process of the battery restraint device 100 carrying and transporting the battery module, the space reserved by the first support member 71 can be used for the camera or other detection equipment to obtain the information of the battery module, even if the length of the first support member 71 is smaller than the length of the battery restraint device 100, it can still reduce the negative impact that the first support member 71 may have on the camera and other detection equipment.

[0153] In this embodiment, the length of the second support member 72 is made smaller than the length of the tray 10, so that when the second limit assembly 30 drives the second support member 72 to move, there is a certain movable space on the tray 10; the length of the first support member 71 is made smaller than the length of the tray 10, and the first support member 71 is arranged on one side of the third limit assembly 60, that is, there is a space between the end of the first support member 71 away from the third limit assembly 60 and the edge of the tray 10, so that the first support member 71 is not easy to extend to the position where the second limit assembly 30 moves, so as to reduce the negative impact of the first support member 71 on the second limit assembly 30, and can also reduce the negative impact of the first support member 71 on other equipment during the battery module transportation, processing or testing process.

[0154] According to some embodiments of the present application, reference Figures 1 to 4 The first limiting component 20 includes a first carrier 21 and a first limiting member 23 connected to the first carrier 21 . The first carrier 21 is movably connected to the tray 10 . The first limiting member 23 is used to abut against the battery module along a first direction.

[0155] The first bearing member 21 refers to a structure in the first limiting assembly 20 for bearing the first limiting member 23 or other structures. The first bearing member 21 may be in the shape of a thin plate, a block, a column or other shapes; the material of the first bearing member 21 may include metal, plastic or other shapes. In some embodiments, the first bearing member 21 is further provided with a first support member 71 and a first connecting member 22.

[0156] The first limit member 23 refers to a structure in the first limit member assembly 20 for limiting the displacement of the battery module. The first limit member 23 can be against the battery module, or can be spaced apart from and opposite to the battery module; the shape of the first limit member 23 can be prism-shaped, cylindrical or other shapes; the first limit member 23 can be directly connected to the first supporting member 21, or can be indirectly connected to the first supporting member 21 through structures such as structural beams and structural columns; the material of the first limit member 23 can include metal, plastic or other materials.

[0157] The first carrier 21 is movably connected to the tray 10. Since the first limit assembly 20 can move along the first direction, the first carrier 21 can also move along the first direction. In some embodiments, a slide groove is provided on the tray 10, and the first carrier 21 is at least partially slidably connected in the slide groove, so that the first carrier 21 can move along the slide groove; in other embodiments, a guide shaft is provided on the tray 10, and the guide shaft passes through the first carrier 21, so that the first carrier 21 can move along the guide shaft; it can be understood that the first carrier 21 and the tray 10 can also be movably connected in other ways, not limited to the above two methods.

[0158] Since the first limiting assembly 20 can move along the first direction, the first limiting member 23 can abut against the battery module along the first direction to limit the displacement of the battery module in the first direction.

[0159] This embodiment provides some detailed structures of the first limiting assembly 20 so that the first limiting assembly 20 can move relative to the tray 10 and limit the displacement of the battery module; at the same time, the first carrier 21 can also provide a fixed foundation for the first support member 71.

[0160] refer to Figure 1 , Figure 2 In some embodiments, a first guide member 11 extending along a first direction is provided on the tray 10 , and the first carrier 21 is slidably connected to the first guide member 11 .

[0161] The first guide member 11 refers to a structure used to enable the first carrier 21 to move along the first direction; the material of the first guide member 11 may include metal, plastic or other materials; the first guide member 11 may be a guide rail arranged on the tray 10, in which case the first carrier 21 is provided with a structure that cooperates with the guide rail so that the first carrier 21 can slide along the guide rail; the first guide member 11 may also be a guide shaft passing through the first carrier 21; the first guide member 11 may also be a guide groove arranged on the tray 10, in which case the first carrier 21 is provided with a structure that can be slidably connected to the guide groove so that the first carrier 21 can slide along the guide groove.

[0162] The first carrier 21 can move along the first guide member 11 relative to the tray 10 to adjust the position of the first limit member 23 relative to the tray 10 , so that the battery restraint device 100 can adapt to battery modules of different specifications.

[0163] This embodiment provides some specific structures for the first limiting component 20 to move along the first direction. A first guide member 11 extending along the first direction is provided on the tray 10, and the first supporting member 21 is slidably connected to the first guide member 11 so that the first limiting component 20 can move along the first direction.

[0165] The second bearing member 31 refers to a structure in the second stopper assembly 30 for bearing the second stopper 33 or other structures. The second bearing member 31 may be in the shape of a thin plate, a block, a column or other shapes; the material of the second bearing member 31 may include metal, plastic or other shapes.

[0167] The second carrier 31 is movably connected to the tray 10. Since the second stopper assembly 30 can move along the second direction, the second carrier 31 can also move along the second direction. In some embodiments, a slide groove is provided on the tray 10, and the second carrier 31 is at least partially slidably connected in the slide groove, so that the second carrier 31 can move along the slide groove; in other embodiments, a guide shaft is provided on the tray 10, and the guide shaft passes through the second carrier 31, so that the second carrier 31 can move along the guide shaft; it can be understood that the second carrier 31 and the tray 10 can also be movably connected in other ways, not limited to the above two methods.

[0168] Since the second limiting assembly 30 can move along the second direction, the second limiting member 33 can abut against the battery module along the second direction to limit the displacement of the battery module in the second direction.

[0169] This embodiment provides some detailed structures of the second limiting assembly 30 so that the second limiting assembly 30 can move relative to the tray 10 and limit the displacement of the battery module; at the same time, the second carrier 31 can also provide a fixed foundation for the second support member 72.

[0170] refer to Figure 1 , Figure 2 In some embodiments, a second guide member 12 extending along the second direction is provided on the tray 10 , and the second supporting member 31 is slidably connected to the second guide member 12 .

[0171] The second guide member 12 refers to a structure used to enable the second carrier 31 to move along the second direction; the material of the second guide member 12 may include metal, plastic or other materials; the second guide member 12 may be a guide rail arranged on the tray 10, in which case the second carrier 31 is provided with a structure that cooperates with the guide rail so that the second carrier 31 can slide along the guide rail; the second guide member 12 may also be a guide shaft passing through the second carrier 31; the second guide member 12 may also be a guide groove arranged on the tray 10, in which case the second carrier 31 is provided with a structure that can be slidably connected to the guide groove so that the second carrier 31 can slide along the guide groove.

[0172] The second carrier 31 can move along the second guide member 12 relative to the tray 10 to adjust the position of the second limit member 33 relative to the tray 10 , so that the battery restraint device 100 can adapt to battery modules of different specifications.

[0173] This embodiment provides some specific structures for the second limiting assembly 30 to move along the second direction. A second guide member 12 extending along the second direction is provided on the tray 10, and the second supporting member 31 is slidably connected to the second guide member 12 so that the second limiting assembly 30 can move along the second direction.

[0174] According to some embodiments of the present application, reference Figure 1 , Figure 6 The battery restraint device 100 also includes an anti-collision member 81 disposed on the tray 10, and the material of the anti-collision member 81 includes an elastic material; one end of the anti-collision member 81 is disposed on the tray 10, and the other end of the anti-collision member 81 extends outside the tray 10 along a direction perpendicular to the thickness of the tray 10.

[0175] The anti-collision member 81 refers to a structure in the battery restraint device 100 used to prevent the tray 10 from directly colliding with external structures; the shape of the anti-collision member 81 can be cylindrical, rectangular or other shapes; the anti-collision member 81 can be installed on the tray 10 by bolts, or by gluing, snap connection or other methods; the anti-collision member 81 can also be installed on one side of the tray 10 only along the movement direction of the battery restraint device 100, or on both sides or more sides of the tray 10.

[0176] The direction perpendicular to the thickness of the pallet 10 is the length direction (X) or the width direction (Y) of the pallet 10. The anti-collision member 81 extends outside the pallet 10 along the direction perpendicular to the thickness of the pallet 10, so that the anti-collision member 81 can collide with the external structure before the pallet 10 during the transportation of the pallet 10, thereby reducing damage to the pallet 10 and buffering the vibration that may be caused by the collision.

[0177] Because the battery restraint device 100 is easy to collide with the edge of the conveying device or other external structures during the transportation process, and is also easy to collide with the gear structure set at the preset position after the battery restraint device 100 reaches the preset position. The tray 10 is easily damaged due to the direct collision with the external structure, and the vibration generated by the collision may also have a negative impact on the battery module. Therefore, one end of the anti-collision member 81 is extended outside the tray 10 so that the anti-collision member 81 can collide with the external structure before the tray 10 to protect the tray 10.

[0178] The material of the anti-collision member 81 includes elastic material. For example, the material of the anti-collision member 81 may include silicone, polyurethane, foam plastic, etc.; because the tray 10 is prone to vibration when colliding with an external structure, the material of the anti-collision member 81 includes elastic material, which can absorb the energy caused by the collision through the elastic material, reduce the occurrence of vibration, and thus reduce the negative impact that the collision may have on the battery module.

[0179] In this embodiment, an anti-collision member 81 is provided on the tray 10, and one end of the anti-collision member 81 extends outside the tray 10, so that the anti-collision member 81 can be collided before the tray 10, thereby playing a role in protecting the tray 10; the material of the anti-collision member 81 includes elastic material to reduce the impact on the battery restraint device 100 when the anti-collision member 81 collides, thereby playing a role in protecting the battery module.

[0180] refer to Figure 6 In some embodiments, a structural member 82 is provided on the tray 10 , and the structural member 82 can form an installation space 821 with at least one end open to accommodate part of the anti-collision member 81 .

[0181] The structural member 82 refers to the structure used to fix the anti-collision member 81 in the battery restraint device 100; the material of the structural member 82 may include metal, plastic or other materials; the structural member 82 may be fixedly connected to the tray 10 by welding, gluing, etc., or may be detachably connected to the tray 10 by bolt connection, snap connection, etc.

[0182] The structural member 82 can form an installation space 821 on the pallet 10, and the installation space 821 is used to accommodate part of the anti-collision member 81. The installation space 821 is mainly used to accommodate the part of the anti-collision member 81 connected to the pallet 10, so as to facilitate the installation of the anti-collision member 81 on the pallet 10 and protect the part of the anti-collision member 81 connected to the pallet 10, thereby reducing the negative impact of the external environment on the connection stability of the anti-collision member 81.

[0183] The installation space 821 may be open at only one end, or may have multiple openings to form an open space; the anti-collision member 81 may abut against the structural member 82 to limit the movement of the anti-collision member 81 on the pallet 10 through the structural member 82, thereby playing a role in assisting in fixing the anti-collision member 81.

[0184] This embodiment provides some specific structures for connecting the anti-collision member 81 to the pallet 10. A structural member 82 is set on the pallet 10, and an installation space 821 is formed by the structural member 82 to facilitate the installation of the anti-collision member 81 on the pallet 10. The displacement of the anti-collision member 81 can also be limited by the structural member 82.

[0185] refer to Figure 6 In some embodiments, the battery restraint device 100 further includes a third connecting member 83 , one end of the third connecting member 83 is connected to the structural member 82 , and the other end of the third connecting member 83 passes through the anti-collision member 81 and is connected to the tray 10 .

[0186] The third connecting member 83 refers to a structure in the battery restraint device 100 for fixing the anti-collision member 81, one end of the third connecting member 83 is connected to the structural member 82 and the other end passes through the anti-collision member 81 and is connected to the tray 10, that is, the third connecting member 83 is not directly connected to the anti-collision member 81, accordingly, the two ends of the third connecting member 83 can be respectively connected to the structural member 82 and the tray 10 by gluing, clamping, screwing, etc.

[0187] Since the anti-collision member 81 is prone to deformation when colliding with an external structure, if the third connecting member 83 is directly connected to the anti-collision member 81, the collision deformation of the anti-collision member 81 will easily have a negative impact on the connection stability of the third connecting member 83; accordingly, the two ends of the third connecting member 83 are respectively connected to the structural member 82 and the tray 10, and the third connecting member 83 is abutted against the anti-collision member 81 to fix the anti-collision member 81, so that the third connecting member 83 can also fix the anti-collision member 81 more stably when the anti-collision member 81 is deformed.

[0188] According to the connection method between the third connecting member 83 and the structural member 82 and the tray 10, the third connecting member 83 may be a bolt, an optical axis or other structures; the material of the third connecting member 83 may include metal, plastic or other materials.

[0189] Since one end of the third connecting member 83 passes through the anti-collision member 81 , a through hole can be provided on the anti-collision member 81 for the third connecting member 83 to pass through. At this time, the third connecting member 83 abuts against the inner wall of the through hole, thereby fixing the anti-collision member 81 .

[0190] The present embodiment further provides some specific structures for connecting the anti-collision member 81 to the pallet 10, so that the third connecting member 83 passes through the anti-collision member 81, and the two ends of the third connecting member 83 are respectively connected to the structural member 82 and the pallet 10; compared with directly connecting the third connecting member 83 to the anti-collision member 81, in this setting, the third connecting member 83 is not directly connected to the anti-collision member 81, thereby reducing the negative impact of the anti-collision member 81 on the connection stability of the third connecting member 83 after being impacted, and at the same time, the third connecting member 83 passing through the anti-collision member 81 can still limit and fix the anti-collision member 81.

[0191] According to some embodiments of the present application, reference Figure 1 , Figure 6 The battery restraint device 100 further includes a guide wheel 90 rotatably connected to the tray 10 .

According to the travel route of the battery restraint device 100 during transportation, the guide wheel 90 may be arranged on one side of the pallet 10 or on multiple sides of the pallet 10.

[0193] The guide wheel 90 can be rotatably connected to the peripheral side of the tray 10. At this time, the guide wheel 90 can contact other external structures before the tray 10, thereby reducing the friction between the battery restraint device 100 and other external structures; the guide wheel 90 can also be rotatably connected to the upper and lower sides of the tray 10. At this time, at least part of the guide wheel 90 can extend outside the tray 10, so that the guide wheel 90 can contact other external structures before the tray 10, thereby reducing the friction between the battery restraint device 100 and other external structures.

[0194] In this embodiment, guide wheels 90 are provided on the pallet 10 to reduce friction between the pallet 10 and other structures during transportation, thereby improving the conveying efficiency and reducing wear of the pallet 10 .
