[0040] The suction hard pipe 710 on the inner plate 133 can have a larger range of movement above the conveying belt 100 to make the suction hard pipe 710 inserted into the cooling liquid interface pipe 111 at different positions, compared with the prior art, when the cooling liquid in the battery pack 110 is extracted, even if the cooling liquid interface pipe 111 is not aligned with the suction hard pipe 710, the two can be matched by moving the suction hard pipe 710, without moving the relatively heavy battery pack 110, and the operation is relatively easy;

[0041] The connecting pipe 130 on the bracket 131 can be lifted to adapt to operators with different heights when the cooling liquid is extracted, and the applicability of the embodiment is increased;

[0042] Specifically, the suction assembly further comprises a containing box 120 arranged below the bracket 131, the bottom end of the connecting pipe 130 extends into the containing box 120, and a suction pump is arranged on the connecting pipe 130, so that the cooling liquid in the battery pack 110 can be discharged through the connecting pipe 130, the suction hard pipe 710 and the suction soft pipe 720.

[0043] In combination Figures 1-4 As shown in the drawings, in the embodiment, the bracket 131 is provided with a through hole through which the connecting pipe 130 passes, the upper end surface of the bracket 131 is provided with a connecting portion 300, the upper end surface of the connecting portion 300 is provided with a circular truncated cone portion 310, the circular truncated cone portion 310 is provided with a plurality of notch grooves 311 along the circumferential direction thereof, and the connecting portion 300 is externally screwed with a driving portion 200, the driving portion 200 is internally provided with an inclined surface 400 matched with the circular truncated cone portion 310, and the driving portion 200 is screwed on the connecting portion 300 for driving the inclined surface 400 to press the circular truncated cone portion 310 so that the circular truncated cone portion 310 tightly holds the connecting pipe 130.

[0044] In the embodiment, the outer side surface of the connecting portion 300 is externally screwed, the inner wall of the driving portion 200 is internally screwed with the outer screw thread, and the two are connected through the screw threads, wherein the circular truncated cone portion 310 is made of a deformable material (such as plastic), and is matched with the notch grooves 311 so that the circular truncated cone portion 310 can tightly hold the connecting pipe 130 to fix the connecting pipe 130.

[0045] Specifically, when the driving portion 200 is rotated around the connecting portion 300 to be screwed on the connecting portion 300, the inclined surface 400 can press the circular truncated cone portion 310 to move close to each other, and the notch grooves 311 are matched to be reduced, so that the circular truncated cone portion 310 tightly holds the connecting pipe 130 to fix the connecting pipe 130, thereby enabling the connecting pipe 130 to be lifted on the bracket 131 to adapt to operators of different heights.

[0046] In combination Figures 2-4 As shown in the drawings, in the embodiment, the outer side wall of the driving portion 200 is provided with a plurality of anti-skid grooves 201 along the axial direction thereof.

[0047] In the embodiment, the anti-skid grooves 201 are arranged to increase the friction when the operator rotates the driving portion 200 to facilitate the rotation of the driving portion 200.

[0048] In combination Figure 5 As shown in the drawings, in the embodiment, one end of the connecting pipe 130 passes through the extension plate 132, and the nuts 500 are externally screwed on the connecting pipes 130 on the upper and lower sides of the extension plate 132.

[0049] In the embodiment, one end of the extension plate 132 is provided with a first mounting hole through which the connecting pipe 130 passes, so that the extension plate 132 can rotate around the connecting pipe 130. The upper and lower ends of the extension plate 132 are limited by the nuts 500, so that the extension plate 132 will not come off the connecting pipe 130 in the axial direction when rotating.

[0050] In combination Figures 1-6 As shown in the drawings, in the embodiment, the extension plate 132 is provided with an extension cavity 600 at the end away from the connecting pipe 130, and one end of the inner plate 133 extends out of the extension cavity 600. The inner plate 133 is further provided with a detachable anti-disengagement piece for preventing the inner plate 133 from disengaging from the extension cavity 600.

[0051] In the embodiment, the extension plate 132 is provided with a sliding groove 522 communicating with the extension cavity 600 at the opposite side surface, and the anti-disengagement piece includes a limiting block 521 provided on the inner plate 133, which can be slidingly arranged in the sliding groove 522.

[0052] Specifically, the limiting block 521 is mounted on the extension plate 132 in the extension cavity 600 by screws, and the limiting block 521 extends out of the sliding groove 522, so that the inner plate 133 will not completely disengage from the extension cavity 600 when sliding in the extension cavity 600. Thus, the inner plate 133 is telescopic, and the suction hard pipe 710 moves accordingly.

[0053] The suction soft pipe 720 is provided with a first bellows 721, which can be deformed when the inner plate 133 moves in the extension plate 132, so that the suction soft pipe 720 is elongated.

[0054] In combination Figures 1-7 As shown in the drawings, in the embodiment, the pressing piece includes a hand cylinder 712 sleeved at the bottom end of the suction soft pipe 720, and the suction hard pipe 710 is arranged at the bottom end of the hand cylinder 712. The bottom end of the suction hard pipe 710 passes through the extended end of the inner plate 133, and the suction hard pipe 710 is sleeved with a spring 711 for moving the hand cylinder 712 upward.

[0055] In the embodiment, the bottom end of the suction hard pipe 710 is further threadedly connected with a limiting ring 700 for limiting the movement distance of the suction hard pipe 710, so that the suction hard pipe 710 is telescopically arranged on the inner plate 133.

[0056] As Figure 7As shown, one end of the spring 711 abuts against the hand holding cylinder 712, and the other end abuts against the inner plate 133. When it is needed to extend the suction hard tube 710 into the cooling liquid interface pipe 111, the suction hard tube 710 can be lowered and extended into the cooling liquid interface pipe 111 by holding the hand holding cylinder 712 and pressing the spring 711, so as to cooperate with the suction pump to suck the cooling liquid. When the hand holding cylinder 712 is released, the hand holding cylinder 712 is lifted up and drives the suction hard tube 710 to separate from the cooling liquid interface pipe 111 under the elastic force of the spring 711. When the limiting ring 700 contacts the bottom end of the inner plate 133, the suction hard tube 710 stops lifting up.

[0057] Specifically, the second bellow 722 is arranged at the end of the suction soft tube 720 close to the hand holding cylinder 712, so that when the suction hard tube 710 is lowered, the second bellow 722 can be elongated to extend the suction hard tube 710 into the cooling liquid interface pipe 111.

[0058] In the embodiment, when it is needed to discharge the cooling liquid in the battery pack 110, first, the height of the connecting pipe 130 on the bracket 131 is adjusted according to the height of the operator, then the battery pack 110 is vertically placed on the conveying belt 100, and the conveying belt 100 is started to transport the battery pack 110. When the battery pack 110 moves to the vicinity of the suction assembly, the conveying belt 100 is stopped, and the suction hard tube 710 is aligned with the cooling liquid interface pipe 111 by rotating the extension plate 132 and moving the inner plate 133. At this time, the presser is pressed to extend the suction hard tube 710 into the cooling liquid interface pipe 111 to suck the cooling liquid in the battery pack 110 and discharge it from the battery pack 110. Then, the conveying belt 100 is started to transport the battery pack 110 after the cooling liquid is discharged.

[0059] In summary, the above only describes the preferred embodiments of the present application, and any changes and modifications made within the scope of the present application should be covered by the present application.
