Description

Technical Field

[0001] The present application relates to the technical field of power battery system assembly, and in particular to a battery module hoist and hoisting equipment. Background Art

[0002] With the development of society and economy, new energy vehicles have gradually entered people's lives. Among them, the power battery system is an indispensable power core of new energy vehicles, and its assembly process directly affects the output and quality of new energy vehicles. The battery module is the most critical part of the power battery system. In the assembly project of the power battery system, the lifting device often uses a battery module hoist to assemble multiple battery modules into a battery pack box to complete the assembly of the power battery system. However, the existing battery module hoists have low safety and poor compatibility. One battery module hoist can only lift one battery module, resulting in low flexibility. In order to meet the needs of different battery modules, only multiple battery module hoists can be designed, which greatly increases the production cost of the power battery system. In addition, different battery module hoists need to be replaced when lifting different battery modules. Due to the high intensity of replacement work, it causes great labor waste and reduces the production efficiency of the power battery system. Summary of the invention

[0003] The embodiments of the present application provide a battery module hanger and a hoisting device to improve the problem of poor compatibility of existing battery module hangers.

[0004] In a first aspect, an embodiment of the present application provides a battery module hanger, comprising a crossbeam and two lifting mechanisms; a lifting piece for lifting is connected to the crossbeam; the two lifting mechanisms are respectively located on both sides of the lifting piece, and each of the lifting mechanisms is used to be connected to one of the lifting parts; wherein the lifting mechanism comprises a lifting assembly and a plurality of connecting assemblies, the plurality of connecting assemblies are arranged on the crossbeam at intervals along the extension direction of the crossbeam, the lifting assembly is used to be selectively connected to one of the plurality of connecting assemblies, and the lifting assembly is used to be connected to the lifting part.

[0005] In the above technical solution, two lifting mechanisms are arranged on the crossbeam, and the two lifting mechanisms are respectively located on both sides of the lifting member to complete the lifting operation of the battery module. The lifting mechanism is provided with a lifting assembly and multiple connecting assemblies for connecting to the lifting part of the battery module. The multiple connecting assemblies are arranged on the crossbeam at intervals, and the lifting assembly can be selectively connected to one of the multiple connecting assemblies. The battery module hoist adopting this structure has good compatibility, so that when lifting battery modules of different sizes, the lifting assembly can be connected to different connecting assemblies or lifting assemblies of different sizes can be replaced to meet the lifting requirements of battery modules of different sizes, so that there is no need to design different battery module hoists for different battery modules in the assembly production line of the power battery system, thereby greatly reducing the production cost of the power battery system, and avoiding frequent replacement of different battery module hoists when lifting battery modules of different sizes, thereby saving labor and improving the operation efficiency of the production line.

[0006] In addition, the battery module hanger provided in the embodiment of the present application also has the following additional technical features:

[0007] In some embodiments, the two lifting mechanisms are symmetrically distributed on both sides of the lifting member in the extension direction of the beam.

[0008] In the above technical solution, two lifting mechanisms are symmetrically arranged on both sides of the lifting piece to improve the stability of the battery module lifter, thereby ensuring the stability of the battery module lifter during the lifting of the battery module, thereby preventing the battery module from tilting and falling off during the lifting process to cause a safety accident.

[0009] In some embodiments, the hanging assembly includes a hanging unit and a plurality of connecting buckles; the plurality of connecting buckles are connected to the hanging unit, and the hanging unit is used to be connected to the hanging part; the connecting assembly includes a plurality of lifting rings, and the plurality of lifting rings are connected to the beam, the lifting rings correspond one-to-one to the connecting buckles, and each connecting buckle is detachably connected to the corresponding lifting ring.

[0010] In the above technical solution, the connecting component is provided with a plurality of lifting rings, and the lifting component is provided with a plurality of connecting buckles, and the plurality of connecting buckles are all connected to the lifting unit, and each connecting buckle is detachably connected to a lifting ring, thereby improving the reliability and stability of the connection of the lifting unit to the beam through the structure in which the plurality of connecting buckles are correspondingly connected to the plurality of lifting rings.

[0011] In some embodiments, the hanging unit includes a connecting plate, a flexible connector and a hanging member; a plurality of the connecting buckles are connected to the connecting plate; the hanging member is connected to the connecting plate through the flexible connector, and the hanging member is used to hang on the hanging part.

[0012] In the above technical solution, the lifting unit is provided with a connecting plate, a flexible connecting member and a hanging member, and a plurality of connecting buckles are all connected to the connecting plate. By connecting one end of the flexible connecting member to the connecting plate and the other end to the hanging member, a flexible connection between the hanging member and the connecting plate is achieved, thereby avoiding a rigid connection between the crossbeam and the battery module. The lifting unit with such a structure is convenient for the operator to buckle the hanging member on the lifting part of the battery module during the lifting operation. The operation is simple and can effectively prevent the hanging member from being separated from the lifting part of the battery module.

[0013] In some embodiments, the connecting plate is provided with a through hole for the connecting buckle to hang.

[0014] In the above technical solution, a through hole is provided on the connecting plate for the connecting buckle to pass through so as to connect the connecting buckle to the connecting plate. This connection method allows the connecting plate to swing relative to the connecting buckle, so that the operator can hook the hanging part on the lifting part of the battery module.

[0015] In some embodiments, the flexible connector includes a nylon webbing or an iron chain.

[0016] In the above technical solution, when an iron chain is used as a flexible connector, since the iron chain has good wear resistance and durability, the wear resistance and durability of the suspension unit can be improved through the flexible connector of this structure, thereby extending the service life of the battery module hanger. When a nylon webbing is used as a flexible connector, since the nylon webbing is elastic, the flexible connector can drive the suspension to rebound after the suspension is buckled on the suspension part of the battery module, so as to realize the self-locking function of the battery module hanger, so that the suspension unit remains in a straight state, thereby preventing the suspension from falling off the suspension part of the battery module, and the nylon webbing is insulating, thereby effectively avoiding the risk of short circuit in the process of lifting the battery module.

[0017] In some embodiments, the lifting member is detachably connected to the beam.

[0018] In the above technical solution, the lifting parts are connected to the crossbeam in a detachable manner to achieve rapid disassembly and replacement of the lifting parts.

[0019] In some embodiments, a mounting hole is provided on the beam; the lifting member is inserted into the mounting hole, and a first limiting portion and a second limiting portion are provided on the lifting member, and the first limiting portion and the second limiting portion are both detachably connected to the lifting member, and the first limiting portion and the second limiting portion respectively abut against both sides of the beam in the thickness direction to prevent the lifting member from detaching from the beam along the thickness direction of the beam.

A first limiting portion and a second limiting portion are provided on the lifting piece. The first limiting portion and the second limiting portion are both detachably connected to the lifting piece. The first limiting portion and the second limiting portion respectively abut against both sides of the crossbeam in the thickness direction to fasten the lifting piece to the crossbeam and prevent the lifting piece from detaching from the crossbeam. Thus, a detachable connection between the lifting piece and the crossbeam is achieved through this structure. This structure is simple, stable and reliable.

[0021] In some embodiments, a weight-reducing groove is provided on the crossbeam.

[0022] In the above technical solution, on the basis of ensuring the strength of the crossbeam, a weight-reducing groove is provided on the crossbeam, thereby reducing the weight of the crossbeam and reducing the overall weight of the battery module hanger.

[0037] Example

[0038] The embodiment of the present application provides a battery module hanger 100, which can improve the low safety and poor compatibility of the existing battery module hanger, thereby causing the battery module hanger to have low flexibility, and further causing the battery power system to have high production costs and low production efficiency. The specific structure of the battery module hanger 100 is described in detail below in conjunction with the accompanying drawings.

[0039] The battery module has two lifting parts for lifting, which are respectively arranged at two opposite end faces of the battery module. The lifting parts are two lifting holes provided on the end faces of the battery module for connection of the battery module lifting tool 100 .

[0040] like Figure 1 As shown, the battery module hanger 100 includes a crossbeam 10 and two lifting mechanisms 20. A lifting member 11 for lifting is connected to the crossbeam 10. The two lifting mechanisms 20 are respectively located on both sides of the lifting member 11, and each lifting mechanism 20 is used to be connected to a lifting part. Among them, the lifting mechanism 20 includes a lifting component 21 and a plurality of connecting components 22, and the plurality of connecting components 22 are arranged on the crossbeam 10 at intervals along the extension direction of the crossbeam 10. The lifting component 21 is used to be selectively connected to one of the plurality of connecting components 22, and the lifting component 21 is used to be connected to the lifting part.

[0041] By arranging two lifting mechanisms 20 on the crossbeam 10, and the two lifting mechanisms 20 are respectively located on both sides of the lifting member 11, the lifting operation of the battery module is completed. The lifting mechanism 20 is provided with a lifting component 21 and a plurality of connecting components 22 for connecting to the lifting part of the battery module. The plurality of connecting components 22 are arranged at intervals on the crossbeam 10, and the lifting component 21 can be selectively connected to one of the plurality of connecting components 22. The battery module hanger 100 adopting this structure has good compatibility, so that when lifting battery modules of different sizes, the lifting component 21 can be connected to different connecting components 22 or the lifting components 21 of different sizes can be replaced to meet the lifting requirements of battery modules of different sizes, so that in the assembly production line of the power battery system, there is no need to design different battery module hangers 100 for different battery modules, thereby greatly reducing the production cost of the power battery system, and avoiding frequent replacement of different battery module hangers 100 when lifting battery modules of different sizes, thereby saving labor and improving the operation efficiency of the production line.

[0042] That is to say, when it comes to battery modules of different models or sizes, the lifting component 21 of the corresponding battery module model is connected to the connecting component 22 at the corresponding position to meet the model matching and size matching of the battery module, thereby completing the lifting function of battery modules of different models or sizes.

[0043] The cross beam 10 is a strip plate structure, and a weight reduction groove 12 is provided on the cross beam 10. On the basis of ensuring the strength of the cross beam 10, the weight reduction groove 12 is provided on the cross beam 10, so that the weight of the cross beam 10 can be reduced, thereby reducing the overall weight of the battery module hanger 100.

[0044] Exemplarily, the material of the crossbeam is aluminum alloy. In other embodiments, the material of the crossbeam can also be steel, plastic, etc.

[0045] Exemplary, combined Figure 1 and Figure 2 As shown, there are two weight-reducing grooves 12, and the two weight-reducing grooves 12 are respectively located on both sides of the lifting member 11. In other embodiments, there may be one, three, four, five, etc. weight-reducing grooves 12.

[0046] The connecting assembly 22 serves to connect the hanging assembly 21. When the hanging assembly 21 is connected to different connecting assemblies 22, battery modules of different sizes can be hung. The number of connecting assemblies 22 can be two, three, four, five, etc. For example, Figure 1 and Figure 2 As shown, there are three connecting components 22.

[0047] In this embodiment, Figure 1As shown, the two lifting mechanisms 20 are symmetrically distributed on both sides of the lifting member 11 in the extension direction of the crossbeam 10. The two lifting mechanisms 20 are symmetrically arranged on both sides of the lifting member 11 to improve the stability of the battery module hanger 100, thereby ensuring the stability of the battery module hanger 100 during the process of lifting the battery module, thereby preventing the battery module from tilting and falling off during the lifting process to cause a safety accident.

[0048] Optionally, combined Figure 1 and Figure 3 As shown, the hanging assembly 21 includes a hanging unit 211 and a plurality of connecting buckles 212. Exemplarily, each hanging assembly 21 is provided with a hanging unit 211, and a plurality of connecting buckles 212 are connected to the hanging unit 211, and the hanging unit 211 is used to be connected to the hanging part. The connecting assembly 22 includes a plurality of lifting rings 221, and the plurality of lifting rings 221 are connected to the crossbeam 10, and the lifting rings 221 correspond to the connecting buckles 212 one by one, and each connecting buckle 212 is detachably connected to the corresponding lifting ring 221.

[0049] The connecting component 22 is provided with a plurality of lifting rings 221, and the lifting component 21 is provided with a plurality of connecting buckles 212, and the plurality of connecting buckles 212 are all connected to the lifting unit 211, and each connecting buckle 212 is detachably connected to a lifting ring 221, thereby improving the reliability and stability of the connection of the lifting unit 211 to the beam 10 through the structure in which the plurality of connecting buckles 212 are correspondingly connected to the plurality of lifting rings 221.

[0050] The lifting ring 221 is detachably connected to the beam 10. In this embodiment, the lifting ring 221 is screwed to the beam 10 by bolts and nuts. In other embodiments, the lifting ring 221 can also be detachably connected to the beam 10 by means of a clamping connection, a pin connection, etc.

[0051] The number of the lifting rings 221 may be two, three, four, five, etc. For example, the number of the lifting rings 221 is two, and the two lifting rings 221 are arranged on the crossbeam 10 at intervals along the width direction of the crossbeam 10. Similarly, the number of the connecting buckles 212 is also two, and each connecting buckle 212 is hung on the corresponding lifting ring 221.

[0052] Exemplarily, the connecting buckle 212 is a carabiner.

[0053] Furthermore, if Figure 3As shown, the hanging unit 211 includes a connecting plate 2111, a flexible connecting member 2112 and a hanging member 2113. A plurality of connecting buckles 212 are connected to the connecting plate 2111. The hanging member 2113 is connected to the connecting plate 2111 through the flexible connecting member 2112, and the hanging member 2113 is used to hang on the hanging part. By connecting one end of the flexible connecting member 2112 to the connecting plate 2111 and the other end to the hanging member 2113, a flexible connection between the hanging member 2113 and the connecting plate 2111 is achieved, so as to avoid a rigid connection between the cross beam 10 and the battery module. The hanging unit 211 with such a structure is convenient for the operator to hang the hanging member 2113 on the hanging part of the battery module during the hanging operation. The operation is simple and can effectively prevent the hanging member 2113 from being separated from the hanging part of the battery module.

[0054] Among them, a first connecting hole 2111a is opened on the connecting plate 2111, and a second connecting hole 2113a is opened on the hanging member 2113. The two ends of the flexible connecting member 2112 are respectively passed through the first connecting hole 2111a and the second connecting hole 2113a to connect the two ends of the flexible connecting member 2112 to the connecting plate 2111 and the hanging member 2113 respectively.

[0055] For example, continue to refer to Figure 3 As shown, the flexible connector 2112 is a nylon webbing. The nylon webbing is used as the flexible connector 2112. Since the nylon webbing is elastic, the flexible connector 2112 can drive the hanging member 2113 to rebound after the hanging member 2113 is hooked on the hanging part of the battery module, so as to realize the self-locking function of the battery module hanger 100, so that the hanging unit 211 is kept in a straight state, thereby preventing the hanging member 2113 from falling off the hanging part of the battery module, and the nylon webbing is insulating, thereby effectively avoiding the risk of short circuit in the process of hanging the battery module.

[0056] It should be noted that, in other embodiments, the flexible connector 2112 may also be an iron chain. When an iron chain is used as the flexible connector 2112, since the iron chain has good wear resistance and durability, the flexible connector 2112 of this structure can improve the wear resistance and durability of the suspension unit 211, thereby extending the service life of the battery module hanger 100.

[0057] Alternatively, if Figure 3As shown, the connecting plate 2111 is provided with a through hole 2111b for the connecting buckle 212 to be hooked, that is, the connecting plate 2111 is provided with two through holes 2111b, and each connecting buckle 212 is inserted into the corresponding through hole 2111b. By providing the through hole 2111b for the connecting buckle 212 to pass through on the connecting plate 2111, the connecting buckle 212 is connected to the connecting plate 2111. This connection method enables the connecting plate 2111 to swing relative to the connecting buckle 212, so that the operator can hook the hanging member 2113 on the hanging part of the battery module. In addition, this structure realizes the detachable connection between the connecting buckle 212 and the connecting plate 2111, so that when the connecting buckle 212 is worn, it is only necessary to replace the connecting buckle 212, thereby reducing the later maintenance cost of the battery module hanger 100. In other embodiments, the connecting buckle 212 can also be connected to the connecting plate 2111 by welding, bonding or screwing.

[0058] In this embodiment, combined with Figure 1 and Figure 4 As shown, the hanging member 2113 includes an end plate 2113b and two pins 2113c, and a second connection hole 2113a for the flexible connecting member 2112 to pass through is provided on the end plate 2113b to connect the end plate 2113b to the flexible connecting member 2112. The two pins 2113c are fixed on the end plate 2113b, and the two pins 2113c are respectively used to hang in two lifting holes on one end surface of the battery module.

[0059] The two pins 2113c are connected to the end plate 2113b by welding. In other embodiments, the two pins 2113c can also be connected to the end plate 2113b by bonding, clamping or screwing.

[0060] Optionally, the hanging member 2113 is further provided with a handle 2113d, which is screwed to the end plate 2113b by bolts, and the handle 2113d and the pin 2113c are respectively located on both sides of the end plate 2113b in the thickness direction, and the operator can drive the end plate 2113b to move through the handle 2113d, so as to hook the two pins 2113c on the hanging part of the battery module, so as to facilitate the use of the operator. In other embodiments, the handle 2113d can also be connected to the end plate 2113b by welding, bonding or clamping.

[0061] It should be noted that, in other embodiments, the hanging assembly 21 can also be other structures, for example, the hanging assembly 21 includes two hanging units 211 and two connecting buckles 212, and each hanging unit 211 is connected to a connecting buckle 212. The hanging unit 211 includes a connecting plate 2111, a flexible connecting member 2112 and a hanging member 2113, the connecting plate 2111 is connected to the connecting buckle 212, and the hanging member 2113 is connected to the connecting plate 2111 through the flexible connecting member 2112. Among them, the hanging member 2113 is a hook pin structure or a hook, and each hanging member 2113 is used to hang in a hanging hole on one end face of the battery module, so that the two hanging units 211 of the hanging assembly 21 can be respectively connected to the two hanging holes on one end face of the battery module, thereby realizing the hanging of the battery module.

[0062] In this embodiment, the lifting member 11 is detachably connected to the cross beam 10. The lifting member 11 is detachably connected to the cross beam 10 to achieve quick disassembly and replacement of the lifting member 11, so that when the lifting member 11 is worn or damaged, only the lifting member 11 needs to be replaced without replacing the entire cross beam 10, thereby reducing the later maintenance cost of the battery module hanger 100.

[0063] Furthermore, combined with Figure 5 and Figure 6 As shown, a mounting hole is provided on the cross beam 10. The lifting member 11 is inserted into the mounting hole, and a first limiting portion 111 and a second limiting portion 112 are provided on the lifting member 11. The first limiting portion 111 and the second limiting portion 112 are both detachably connected to the lifting member 11, and the first limiting portion 111 and the second limiting portion 112 are respectively pressed against two sides of the cross beam 10 in the thickness direction to prevent the lifting member 11 from being separated from the cross beam 10 in the thickness direction of the cross beam 10.

[0064] A mounting hole is provided on the crossbeam 10, and the lifting member 11 is inserted into the mounting hole. A first limiting portion 111 and a second limiting portion 112 are provided on the lifting member 11, and the first limiting portion 111 and the second limiting portion 112 are both detachably connected to the lifting member 11. The first limiting portion 111 and the second limiting portion 112 respectively abut against both sides of the crossbeam 10 in the thickness direction to fasten the lifting member 11 to the crossbeam 10 and prevent the lifting member 11 from detaching from the crossbeam 10, thereby realizing a detachable connection between the lifting member 11 and the crossbeam 10 through this structure. This structure is simple, stable and reliable.

[0065] Exemplarily, the lifting member 11 is a plate-like structure, and a lifting hole 113 for lifting is provided at one end of the lifting member 11. In other embodiments, the lifting member 11 may also be other structures, for example, the lifting member 11 includes a first rod and a second rod, the first rod is detachably connected to the cross beam 10, the second rod is fixed to the first rod and is perpendicular to the first rod, so that the first rod and the second rod are in a T-shaped structure, and the second rod is used to be connected to the lifting device.

[0066] Among them, continue to combine Figure 5 and Figure 6 As shown, the first limit portion 111 is two limit blocks arranged on the lifting member 11, and the two limit blocks are respectively arranged on both sides of the lifting member 11 in the thickness direction, and the two limit blocks are screwed to the lifting member 11 by bolts. In other embodiments, the two limit blocks can also be detachably connected to the lifting member 11 by other means, for example, the two limit blocks are connected to the lifting member 11 by means of clamping, buckling, etc.

[0067] Furthermore, one end of the lifting member 11 away from the lifting hole 113 is inserted into the mounting hole of the cross beam 10, and the second limiting portion 112 is a pin provided on the lifting member 11. The second limiting portion 112 is connected to one end of the lifting member 11 away from the lifting hole 113, and the second limiting portion 112 is farther from the lifting hole 113 than the first limiting portion 111. A pin hole is provided on the lifting member 11, and the second limiting portion 112 is inserted into the pin hole and is screwed to the lifting member 11 by bolts, so that the first limiting portion 111 and the second limiting portion 112 are respectively against the two sides of the cross beam 10 in the thickness direction. Thus, through this structure, the lifting member 11 is detachably connected to the cross beam 10, and the connection strength between the lifting member 11 and the cross beam 10 is guaranteed.

[0068] Optionally, after the first limiting portion 111 abuts against the cross beam 10 , it is screwed to the cross beam 10 by bolts, so as to improve the connection strength between the lifting member 11 and the cross beam 10 .

[0069] It should be noted that, in other embodiments, the lifting member 11 may be detachably connected to the cross beam 10 in other ways, for example, the lifting member 11 is directly screwed to the cross beam 10 by bolts.

[0070] In addition, the present application also provides a lifting device, including a lifting device and the above-mentioned battery module lifting device 100. The lifting device is connected to the lifting member 11 through a lifting hole 113 provided on the lifting member 11, and the lifting device is used to drive the battery module lifting device 100 to move.

[0071] By connecting the battery module hanger 100 to the lifting device, the lifting device can drive the battery module hanger 100 to move to complete the lifting of the battery module. The lifting equipment with this structure can lift battery modules of different sizes, which improves the compatibility of the lifting equipment. When lifting battery modules of different sizes with the lifting equipment of this structure, there is no need to frequently replace different battery module hangers, which greatly saves labor costs and effectively improves the efficiency of the lifting operation. In addition, the lifting equipment of this structure is relatively safe and can effectively prevent the battery module from falling off during the lifting process.

[0072] Exemplarily, the lifting device can be an electric hoist, a manual hoist, a lifting tackle, a gantry crane, a lift, etc.
