TECHNICAL FIELD

[0001] The application relates to the technical field of new energy automobile battery maintenance, and in particular to a battery fire-fighting box for automobile repair. BACKGROUND

[0002] The new energy automobile refers to an automobile adopting unconventional vehicle fuel as a power source (or using conventional vehicle fuel, adopting a new vehicle power device), and combining the advanced technology of vehicle power control and driving to form an automobile with advanced technical principles and new technology and structure. The new energy automobile includes a pure electric automobile, a range-extender electric automobile, a hybrid electric automobile, a fuel cell electric automobile, a hydrogen engine automobile and the like.

[0003] At present, the pure electric automobile has been popularized in an all-round way, but the battery of the pure electric automobile is prone to danger when subjected to external damage. The battery pack of the new energy automobile has a special protection structure, but to some extent, it is no different from the Pandora's box. As long as the monomer is broken or the structure is changed, for example, the internal battery cell is exposed to air, or the positive and negative poles of the battery are in contact, the battery cell material will rapidly react chemically, and thermal runaway will occur.

[0004] During automobile repair, the battery pack needs to be placed in a special place for repair, and the place should have the function of emergency fire extinguishing. In the prior art, a water storage tank is generally placed beside the workbench, and when an accident occurs, the battery pack is pushed into the water storage tank in time to ensure that no greater danger occurs.

A reset handle 61 is installed on the hand-cranked bearing seat 6, and a wire rope 8 is fixed on the pawl of the ratchet bearing seat 7. A hand-cranked wheel group 9 and a roller 101 are also installed on the long side panel 13 on the side of the ratchet bearing seat 7. The wire rope 8 passes around the hand-cranked wheel group 9 and the roller 101 respectively, and the hand-cranked wheel group 9 can pull the wire rope 8. The hand-cranked wheel group 9 includes a seat body 91, a rotating body 92 and a rotating arm 93. The seat body 91 is fixed on the long side panel 13, the rotating body 92 is rotatably connected to the side of the seat body 91, and the rotating arm 93 is fixed on the rotating body 92. The rotating body 92 has a plurality of connecting columns for winding the wire rope 8; In order to prevent personnel from operating incorrectly, a pin hole 71 is opened on the body of the ratchet bearing seat 7, and a pin shaft 72 is matched in the pin hole 71. The pin shaft 72 is used to limit the pawl. An anti-lost rope 73 is fixed on the pin shaft 72, and the anti-lost rope 73 is fixed on the long side panel 13.

[0021] Specifically, refer to Figure 1 and Figure 6 In order to facilitate lifting, lifting rings 31 are fixed at the four corners of the surface of the supporting plate 3, and a water inlet 32 ​​is opened on the surface of the supporting plate 3. The supporting plate 3 is spliced ​​by two grilles 33. The two grilles 33 are locked by multiple bolts. The bolt locking connection is relatively firm. Several through holes are opened on the surface of the grille 33. The through holes can facilitate water flow, so that the supporting plate 3 can fall quickly as a whole.

[0022] Specifically, refer to Figure 8 The bottom plate 11 is made up of two bottom frames 111, which are connected by quick buckles, and a sealing strip is provided between the two bottom frames 111. Since the bottom frames 111 are in a planar state, they can be firmly connected together after being pulled together by quick buckles, so that they can be assembled quickly and conveniently.

[0023] Specifically, refer to Figure 5 The long side panel 13 is spliced ​​by two long side frames 131, the two long side frames 131 are fixed by bolts, and the long side panel 13 and the wide side panel 12 are fixed by bolts. After the long side panel 13 and the wide side panel 12 are fixed by bolts, the long side frame 131 and the bottom plate 11 are connected by quick buckles.

[0024] The split box body 1 is assembled from a plurality of panels and connected by bolts and quick buckles, which ensures overall strength while the quick buckles can improve assembly efficiency. When disassembled, it is convenient to pack and transport, greatly saving logistics costs.

[0025] Reference Figure 1 and Figure 3 A wide side baffle 102 is installed on the top of the wide side panel 12, and a long side baffle 103 is installed on the top of the long side panel 13. Adjustment grooves are provided on the surfaces of the wide side baffle 102 and the long side baffle 103. The wide side baffle 102 can move on the top of the wide side panel 12, and the long side baffle 103 can move on the top of the long side panel 13.

[0026] By providing the wide side baffle 102 and the long side baffle 103, the gap between the supporting plate 3 and the split box body 1 can be covered. On the one hand, foreign matter can be prevented from entering the split box body 1, and on the other hand, water overflowing when the supporting plate 3 falls can be blocked.

[0027] The implementation principle of a battery fire extinguisher box for auto repair in the embodiment of the present application is as follows: In the initial state, the staff can place the battery pack on the supporting plate 3 for maintenance. When a danger occurs, close the ball valve 41 and quickly fill the fire box with water from the water inlet 32 ​​(water can also be stored in the split box 1). The staff pulls out the pins 72 on both sides and pushes the rotating arm 93 in the hand-cranked wheel group 9. The rotating arm 93 drives the rotating body 92 to rotate. The rotating body 92 pulls the wire rope 8. The wire rope 8 pulls the pawls on the ratchet bearing seats 7 on both sides to disengage. The rotating shaft 5 loses its supporting force and rotates. The supporting plate 3 falls into the split box 1 together with the battery pack, and ensures that the clean water covers the battery pack by more than 20 cm. Soak for more than 48 hours, then drain and remove the battery pack and supporting plate 3.

[0028] When resetting the supporting plate 3, pull the reset handle 61 to return the supporting plates 51 on the two side shafts 5 to a horizontal state, insert the pin shaft 72 into the pin hole 71, slide the wide side baffle 102 and the long side baffle 103 so that the opening is larger than the supporting plate 3, put the supporting plate 3 on, and push the wide side baffle 102 and the long side baffle 103 again to cover the supporting plate 3.

[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
