When the side cover plate I1 and the side cover plate II 2 are closed, the limiting component 508 does not limit the upper cooling plate 501 any more, and the upper cooling pipe 502 is in contact with the charger.
The limiting component 508 comprises a sliding rail I511, the sliding rail I511 is fixedly installed on the upper cooling plate 501, a cross bar 512 is installed in the sliding rail I511 in a sliding mode, the cross bar 512 is installed in the sliding rail II 515 in a sliding mode, and the sliding rail II 515 is fixedly installed at the top of the inner side of the side cover plate II 2; a limiting spring 513 is fixedly arranged on the cross rod 512, a limiting plate 514 is fixedly arranged on the limiting spring 513, and the limiting plate 514 is fixedly arranged on the side cover plate II 2. The limiting spring 513 enables the cross rod 512 to abut against the sliding rail I511, and the reliability of the cross rod 512 and the sliding rail I511 when the side cover plate I1 and the side cover plate II 2 are not closed is guaranteed. Push rods 516 are fixedly installed at the tops of the inner sides of the side cover plates I1, and when the side cover plates I1 are in contact with the side cover plates II 2 to be closed, the push rods 516 push the cross rods 512 out of the sliding rails I511. When the cross bar 512 is separated from the slide rail I511, the upper cooling plate 501 and the side cover plate II 2 are connected together only by the pressing spring III 510. Cooling module 5 still includes extrusion spring I507 and extrusion spring II 509, and extrusion spring I507 fixed mounting is between side apron I1 and side cooling plate I503, and extrusion spring II 509 fixed mounting is between side apron II 2 and side cooling plate II 506.
Before the device is used, a side cover plate I1 and a side cover plate II 2 are in a separated state, and a charger is placed on a bottom plate 7; then the side cover plate I1 and the side cover plate II 2 are closed, the side cooling plate I503 is driven by the extrusion spring I507 in the process, and the side cooling plate I503 moves to the upper part of the middle part of the bottom plate 7 along with the side cover plate I1; the side cooling plate II 506 is driven by the extrusion spring II 509, and the side cooling plate II 506 moves towards the upper part of the middle part of the bottom plate 7 along with the side cover plate II 2; when the side cooling pipe I504 and the side cooling pipe II 505 touch the side face of the charger, the extrusion spring I507 and the extrusion spring II 509 are compressed, the space in the cooling assembly 5 is more fit and adapted to the size of the charger, when the side cover plate I1 and the side cover plate II 2 are closed, the push rod 516 approaches the cross rod 512 along with the side cover plate I1, and finally the cross rod 512 is jacked to push the cross rod 512 out of the slide rail I511; when the cross bar 512 is completely separated from the sliding rail i 511, the pressing spring iii 510 pushes the upper cooling plate 501 to move downwards, so that the upper cooling pipe 502 is attached to the top surface of the charger. Then, the coolant in the cooling tank 3 flows into the cooling module 5 through the communication pipe 4, and dissipates heat to the charger on the base plate 7, and the communication pipe 4 is a hose and has a deformation margin, so that the coolant can adapt to the position change of the upper cooling pipe 502, the side cooling pipe i 504 and the side cooling pipe ii 505.
As shown in fig. 5, 6 and 7, the guide assembly i 8 includes a mounting block 804 and a guide runner 811. The mounting block 804 and the guide runner 811 are fixedly mounted on the top of the inner side of the side cover plate i 1, and are close to the corners. A guide block 803 is slidably mounted in the guide sliding groove 811, a clamping rod 805 is slidably mounted on the guide block 803, the clamping rod 805 is slidably mounted with the mounting block 804, and the middle part of the outer side of the clamping rod 805 is fixed with one end of a small spring 807; the other end of the small spring 807 is fixedly connected with the inner side of the side cover plate I1; a guide plate 802 is fixedly arranged below the guide block 803, a plurality of vertical springs 801 are fixedly arranged on the guide plate 802, and the vertical springs 801 are fixedly connected with the side cover plate I1. And a contact block I808 and a contact block II 810 are respectively fixed at two ends of each toggle spring 809. The contact block I808 is hinged to the side cover plate I1; the contact block II 810 is hinged on the side cooling plate I503. A rotating plate 806 is hinged on the side cover plate I1, and the top surface of the rotating plate 806 is in contact with the bottom of the clamping rod 805; the bottom surface of the rotating plate 806 is in contact with one of the contact blocks i 808. A guide groove plate 812 is fixedly arranged on the side cooling plate I503. The top of the guide slot plate 812 is provided with a plurality of guide sliding slots; the top of the guide plate 802 is provided with a plurality of guide projections. Each guide sliding groove is aligned with each guide convex block respectively. In the case where the locking bar 805 is slidably coupled to the guide block 803, the guide chutes are separated from the guide protrusions.
Under the condition that the side cover plate I1 and the side cover plate II 2 are closed, the contact block I808 on the same toggle spring 809 is lower than the contact block II 810, namely the toggle spring 809 is in an inclined state; therefore, in the process that the side cover plate I1 moves inwards relative to the side cooling plate I503, the toggle spring 809 shortens, the inclination degree gradually increases, and the contact block I808 further pushes the rotating plate 806 to turn upwards. Therefore, in the process of closing the side cover plate I1 and the side cover plate II 2, the contact block I808 rotates on the side cover plate I1, and the rotating contact block I808 drives the rotating plate 806; the turning plate 806 that overturns pushes the clamping rod 805 to slide outwards, the clamping rod 805 gradually separates from the guide block 803 along the mounting block 804 outwards, after the clamping rod 805 separates from the guide block 803, the guide block 803 slides downwards in the guide sliding groove 811, the guide block 803 drives the guide plate 802, the vertical spring 801 also pushes the guide plate 802 to slide downwards so that the guide sliding groove on the guide groove plate 812 and the guide projection on the guide plate 802 form a sliding fit, and then the side cooling plate i 503 can slide along the notch of the guide plate 802 and is not inclined any more.
