[0030] In order to improve the energy density per unit volume, the existing battery modules will omit the end plates and process the battery modules without end plates. Eliminating the end plates can save the space occupied by the end plates, so that more cells can be arranged to increase the capacity of the battery modules. However, the existing battery modules need to be hoisted by the end plates during the production process, and the corresponding connection structure on the end plates is hooked by the hooks. Therefore, it is difficult to hoist the battery modules after the end plates are eliminated.

[0031] In view of the above problems, the utility model provides a battery module hoist 100 without end plates, which can clamp and limit the battery module 80 without end plates, thereby hoisting the battery module 80 without end plates so that it can flow between various workstations of the processing production line.

[0032] See also Figure 1-Figure 4The end plate-less battery module hanger 100 includes a top plate 101, a first limiting assembly 10 and a second limiting assembly 20. The top plate 101 has a bottom surface facing the battery module 80 and a top surface facing away from the battery module 80. The first limiting assembly 10 includes a first limiting plate 11 and a second limiting plate 12. The first limiting plate 11 is connected to the bottom surface of the top plate 101, the second limiting plate 12 is connected to the first limiting plate 11, and the first limiting plate 11 and the second limiting plate 12 are set at an angle; the second limiting assembly 20 includes a third limiting plate 21 and a fourth limiting plate 22. The third limiting plate 21 is connected to the bottom surface of the top plate 101, the fourth limiting plate 22 is connected to the third limiting plate 21, and the third limiting plate 21 and the fourth limiting plate 22 are set at an angle; at least one of the first limiting assembly 10 and the second limiting assembly 20 can move toward the other to clamp the battery module 80 located therebetween. In this way, the first limiting assembly 10 and the second limiting assembly 20 can clamp the battery module 80 from two directions, thereby limiting the battery module 80 and driving the battery module 80 to move, so as to realize the circulation of the battery module 80 without end plates between workstations. In addition, since the first limiting assembly 10 includes the first limiting plate 11 and the second limiting plate 12 set at an angle, the first limiting plate 11 and the second limiting plate 12 can respectively abut against the two surfaces of the battery module 80, and similarly, the third limiting plate 21 and the fourth limiting plate 22 can also abut against the two surfaces of the battery module 80, so the clamping and limiting of the battery module 80 by the first limiting assembly 10 and the second limiting assembly 20 is more stable.

[0033] The first limiting plate 11, the second limiting plate 12, the third limiting plate 21 and the fourth limiting plate 22 are all provided with limiting pads 121 on the side facing the battery module 80. The limiting pads 121 are made of soft material, such as rubber, to increase the friction between the first limiting assembly 10 and the second limiting assembly 20 and the battery module 80, and also prevent the outer wall of the battery module 80 from being bumped and damaged.

[0034] Furthermore, the end plate-free battery module hanger 100 further includes a driving assembly 30, which is connected to the first limiting assembly 10 and / or the second limiting assembly 20, and can drive the first limiting assembly 10 to move toward the second limiting assembly 20, and / or can drive the second limiting assembly 20 to move toward the first limiting assembly 10. In this way, the first limiting assembly 10 and the second limiting assembly 20 are driven by the driving assembly 30, which is convenient for control and saves manpower.

[0035] In other embodiments, the first limiting assembly 10 and the second limiting assembly 20 can also be driven by manual operation to save the material and assembly costs of the driving assembly 30 .

[0036] The end plate-free battery module hanger 100 further includes a slide rail 40 and a slide seat 41, wherein the slide rail 40 is connected to the bottom surface of the top plate 101, the slide seat 41 is slidably connected to the slide rail 40 and can move along the slide rail 40, the first position-limiting assembly 10 is connected to the slide seat 41, and the driving assembly 30 is connected to the first position-limiting assembly 10 and can drive the first position-limiting assembly 10 to move along the length direction of the slide rail 40. In this way, the slide seat 41 can move along the length direction of the slide rail 40, so the slide rail 40 can guide the moving direction of the slide seat 41, and since the first position-limiting assembly 10 is connected to the slide seat 41, the slide rail 40 can also guide the moving direction of the first position-limiting assembly 10, thereby making the movement of the first position-limiting assembly 10 more stable.

[0037] Of course, both the slide rail 40 and the slide seat 41 can be set to two, and the second limit assembly 20 is also connected to the slide rail 40 through the slide seat 41 and moves along the slide rail 40, so that the first limit assembly 10 and the second limit assembly 20 both move toward the battery module 80 to increase work efficiency.

[0038] It can be understood that in other embodiments, the slide rail 40 can also be set as a screw structure, and the sliding seat 41 is threadedly matched with the slide rail 40. When the slide rail 40 rotates, the sliding seat 41 can move along the screw structure.

[0039] The first limiting assembly 10 further includes a first connection seat 13, the first connection seat 13 is connected to the sliding seat 41, and the first limiting plate 11, the second limiting plate 12 and the driving assembly 30 are all connected to the first connection seat 13. In this way, the driving assembly 30 is connected to the first connection seat 13 and can drive the first connection seat 13 to move. Since the first limiting plate 11 and the second limiting plate 12 are both connected to the first connection seat 13, the driving assembly 30 can drive the first limiting plate 11 and the second limiting plate 12 at the same time.

[0040] The first limiting plate 11 and the second limiting plate 12 are both located at one end of the first connection seat 13 away from the top plate 101, and an escape space is formed between the second limiting plate 12 and the top plate 101, and the escape space can accommodate at least part of the driving assembly 30. Since the first limiting plate 11 and the second limiting plate 12 are connected to one end of the first connection seat 13 away from the top plate 101, the first limiting plate 11 and the second limiting plate 12 are spaced a certain distance from the top plate 101 to form a space for installing the driving assembly 30. Thereby, the space occupied by the driving assembly 30 on the top surface of the top plate 101 is reduced, and the driving assembly 30 is convenient to drive the first limiting assembly 10 without setting an additional transmission mechanism.

[0041] Of course, in other embodiments, the driving assembly 30 may also be disposed on the top surface of the top plate 101 to facilitate assembly.

[0042] Furthermore, the driving assembly 30 includes a switch 31 and a driving source 32. The switch 31 can trigger the start of the driving source 32. The switch 31 is arranged on the top surface of the top plate 101, and the driving source 32 is arranged on the bottom surface of the top plate 101 and is located in the avoidance space. In this way, the switch 31 can trigger the driving source 32, so that the driving source 32 drives the first connecting seat 13. The driving source 32 is arranged on the bottom surface of the top plate 101, which is closer to the first limit assembly 10, so as to facilitate the layout of the driving source 32. The switch 31 is arranged on the top surface of the top plate 101, which is convenient for workers to operate.

[0043] In this embodiment, the driving source 32 is configured as a cylinder, the switch member 31 is configured as a manual valve, the manual valve controls the movement of the cylinder, and an actuating rod that can be extended or retracted is provided on the cylinder, and the actuating rod drives the first connecting seat 13 to move.

[0044] Further, in this embodiment, the second limit assembly 20 may also be provided with a second connection seat, the third limit plate 21 and the fourth limit plate 22 are both connected to the second connection seat, and the second connection seat is fixedly connected to the bottom surface of the top plate 101. Alternatively, the third limit plate 21 is directly connected to the top plate 101, and the fourth limit plate 22 is fixedly connected to the top plate 101 through the third limit plate 21. During the hoisting process, the second limit assembly 20 remains stationary, and the first limit assembly 10 moves toward the battery module 80 to cooperate with the second limit assembly 20 to clamp the battery module 80.

[0045] The battery module hoist without end plate 100 further includes a protection assembly, which includes a first protection unit 50 and a second protection unit 60. The first protection unit 50 and the second protection unit 60 are located on both sides of the width direction of the top plate 101 and can be rotated to the lower side of the battery module 80. In this way, the first protection unit 50 and the second protection unit 60 can limit the lower bottom surface of the battery module 80, stop the downward movement of the battery module 80, and prevent the battery module 80 from falling during the hoisting process.

[0046] The first protective unit 50 includes a first rotating plate 51 and a first protective plate 52. The first rotating plate 51 is rotatably connected to the first limiting assembly 10, and the first protective plate 52 is connected to one end of the first rotating plate 51 away from the first limiting assembly 10, and the first rotating plate 51 and the first protective plate 52 are arranged at an angle; the second protective unit 60 includes a second rotating plate 61 and a second protective plate 62. The second rotating plate 61 is rotatably connected to the second limiting assembly 20, and the second protective plate 62 is connected to one end of the second rotating plate 61 away from the second limiting assembly 20, and the second rotating plate 61 and the second protective plate 62 are arranged at an angle.

[0047] In this way, the first protective plate 52 is connected to one end of the first rotating plate 51 away from the top plate 101, and there is a space for installing the battery module 80 between the first protective plate 52 and the top plate 101, and similarly, there is a space for installing the battery module 80 between the second protective plate 62 and the top plate 101. In addition, the first rotating plate 51 and the first protective plate 52 are arranged at an angle, so the first rotating plate 51 and the first protective plate 52 can limit the battery module 80 in two directions, and similarly, the second rotating plate 61 and the second protective plate 62 can also limit the battery module 80 in two directions, thereby improving the protection effect of the first protective unit 50 and the second protective unit 60 on the battery module 80.

[0048] Exemplarily, a groove 111 is provided on the first limit plate 11, the first rotating plate 51 is embedded in the groove 111, and the rotating shaft 112 is provided on the first rotating plate 51 and the two side walls of the groove 111, and the first rotating plate 51 can rotate around the rotating shaft 112 to achieve rotation relative to the first limit plate 11. Grooves 111 are provided at both ends of the length direction of the first limit plate 11, and the first rotating plate 51 is rotatably connected to the two grooves 111 to improve the connection strength between the first limit plate 11 and the first rotating plate 51. The cooperation between the second limit plate 12 and the second rotating plate 61 is also the same as above, and will not be repeated here.

[0049] In this embodiment, the first protection unit 50 and the second protection unit 60 are both manually operated, and after the first limiting plate 11 and the second limiting plate 12 complete the clamping of the battery module 80, the first protection unit 50 and the second protection unit 60 are manually rotated to a preset position. In other embodiments, the first protection unit 50 and the second protection unit 60 can also be driven by a motor.

[0050] See also Figure 5 The utility model also provides a processing production line for an end plate-less battery module 80, including the end plate-less battery module hanger 100 and the clamping device 70 as described above. The clamping device 70 can clamp the battery module 80 and drive the battery module 80 to flow in various workstations in the processing production line for the end plate-less battery module 80. The end plate-less battery module hanger 100 can clamp the battery module 80 through the first limiting assembly 10 and the second limiting assembly 20, and hoist the battery module 80. The clamping device 70 is configured to release the battery module 80 before the end plate-less battery module hanger 100 moves.

[0051] The clamping device 70 includes a base plate 73, a first clamping assembly 71 and a second clamping assembly 72.

In this way, the bottom plate 73 provides a supporting force below the battery module 80, and the first clamping assembly 71 and the second clamping assembly 72 are arranged at both ends of the length direction of the bottom plate 73, that is, at both ends of the battery module 80. The first clamping plate 711 and the second clamping plate move toward each other and clamp the battery module 80, thereby limiting the battery module 80, and the first clamping plate 711 and the second clamping plate are both plate-like structures, so the contact area with the battery module 80 is large, preventing damage to the end of the battery module 80, and the first clamping plate 711 and the second clamping plate are both provided with electrode connection holes electrically connected to the battery module 80, so when the electrodes of the charging and discharging test equipment contact the first clamping plate 711 and the second clamping plate, the electrode connection hole can be used as a fixing hole for the electrode, that is, an external connector is used to penetrate the electrode and the electrode connection hole, so that the connection between the electrode and the first clamping plate 711 and the second clamping plate is more stable, thereby facilitating normal charging and discharging testing of the battery module 80.
