[0033] In order to enable those skilled in the art to better understand the technical solutions in the present utility model, the following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0034] As Figures 1-6 shown, a lithium battery power supply for a mine cage in an embodiment of the present utility model includes a BMS protection board 1, a chassis, a battery module 5, and multiple groups of plugs. The chassis is assembled by a chassis main body 2 and a packaging board 3. Both the BMS protection board 1 and the battery module 5 are fixedly connected inside the chassis main body 2.

[0035] Among them, the BMS protection board 1 can be directly fixed on the inner wall of the chassis main body 2 by bolts.

[0036] As Figure 1 , Figure 3 and Figure 6 shown, a fixing component is installed inside the chassis main body 2. The fixing component includes four groups of fixing screw rods 203. The four groups of fixing screw rods 203 are all welded and fixed at the bottom end inside the chassis main body 2. Four groups of jacks 501 are provided on the battery module 5. The four groups of fixing screw rods 203 correspond to the four groups of jacks 501 one by one.

[0037] Specifically, the diameter of the jack 501 is larger than the diameter of the fixing screw rod 203, and the length of the fixing screw rod 203 is greater than the length of the jack 501. The top end of the fixing screw rod 203 can penetrate to the upper end of the jack 501. During the process of installing the battery module 5 inside the chassis main body 2, the four groups of fixing screw rods 203 are respectively passed through the four groups of jacks 501, and then the battery module 5 can be pressed and fixed by using nuts matching the fixing screw rods 203.

[0038] As Figure 1 and Figure 2 shown, the packaging board 3 is sleeved and fixed on the top end of the chassis main body 2. A plurality of assembly screw holes 201 are provided at a position near the top end on the side wall of the chassis main body 2. A plurality of assembly through holes 301 are provided on the packaging board 3. The plurality of assembly screw holes 201 correspond to the plurality of assembly through holes 301 one by one. When the chassis main body 2 is sleeved on the top end of the BMS protection board 1, the plurality of assembly screw holes 201 can just coincide with the plurality of assembly through holes 301, and then bolts matching the assembly screw holes 201 are screwed in to realize the assembly and fixation of the packaging board 3 and the chassis main body 2.

[0039] As Figure 4 and Figure 5As shown in the figure, an edge sealing assembly is installed on the encapsulation board 3. The edge sealing assembly includes a boss 302, and the boss 302 is fixedly connected to the top end inside the encapsulation board 3. A sealing edge bladder 303 is adhesively fixed at the edge position of the boss 302. After the encapsulation board 3 is sleeved on the top end of the chassis main body 2, the sealing edge bladder 303 can expand and tightly adhere to the inner wall of the chassis main body 2, realizing the sealing of the gap between the chassis main body 2 and the encapsulation board 3.

[0040] A strip-shaped groove 3021 is formed on the boss 302, and a strip-shaped tube 305 is fixedly connected inside the strip-shaped groove 3021. A pair of circular grooves 3022 are formed on the strip-shaped groove 3021, and a pair of protruding bladders 304 are fixedly connected to the strip-shaped tube 305. The pair of protruding bladders 304 are respectively fixedly connected inside the pair of circular grooves 3022. The pair of protruding bladders 304 and the strip-shaped tube 305 are integrally formed. Among them, the protruding bladders 304 protrude outwards in the initial state and can contract towards the inside of the circular grooves 3022 when subjected to pressure.

[0041] Both ends of the strip-shaped tube 305 are communicated with the inside of the sealing edge bladder 303. When the protruding bladders 304 are compressed and contracted, the internal air pressure can be conducted to the inside of the sealing edge bladder 303 through the strip-shaped tube 305, causing the sealing edge bladder 303 to expand.

[0042] Specifically, when assembling the encapsulation board 3 onto the chassis main body 2, first preliminarily sleeve the encapsulation board 3 onto the chassis main body 2. At this time, the pair of protruding bladders 304 are in contact with the upper end surface of the battery module 5, and the assembly through holes 301 do not coincide with the assembly screw holes 201. At this time, press the encapsulation board 3 downwards. Due to the pressure, the protruding bladders 304 contract towards the inside of the circular grooves 3022, and the encapsulation board 3 gradually moves downwards until the assembly through holes 301 coincide with the assembly screw holes 201. During this process, the internal air pressure of the protruding bladders 304 will gradually be conducted to the sealing edge bladder 303, causing the sealing edge bladder 303 to gradually expand and gradually adhere to the inner wall of the chassis main body 2. With the help of the sealing edge bladder 303, a seal can be formed at the joint between the chassis main body 2 and the encapsulation board 3, preventing the intrusion of water vapor and impurities, improving the protection effect of the chassis on the battery module 5, and extending the service life of the battery module 5.

[0043] It should be noted that at this time, the protruding bladders 304 can also have a reaction force on the battery module 5, playing a role in pressing and fixing the battery module 5, so that the battery module 5 has a double fixing effect inside the chassis main body 2, improving the stability of the battery module 5 inside the chassis main body 2.

[0044] As Figure 1 and Figure 2 shown, a pair of handles 4 are fixedly installed on the encapsulation board 3, and the pair of handles 4 are both rotatable handles. Through the pair of rotatable handles 4, it is convenient to carry and transfer the lithium battery power supply.

[0045] Four sets of fixed feet 202 are fixedly connected to the main chassis body 2. Corresponding bolt holes are provided on the four sets of fixed feet 202. Through the four sets of fixed feet 202, it is convenient to install this lithium battery power supply at the designated position of the mine cage by using bolts. The bolt installation method facilitates the disassembly, installation and maintenance of this lithium battery power supply inside the mine cage.

[0046] The multiple sets of plugs include a charging positive aviation plug 6, a discharging negative aviation plug 7, and a communication aviation plug 8. The charging positive aviation plug 6, the discharging negative aviation plug 7, and the communication aviation plug 8 are fixedly connected to the main chassis body 2 in sequence.

[0047] Furthermore, the welding positive pin of the charging positive aviation plug 6 is electrically connected to the total positive of the battery module 5; the welding negative pin of the discharging negative aviation plug 7 is electrically connected to the BMS protection board 1; the BMS protection board 1 is electrically connected to the total negative of the battery module 5; the welding pin of the communication aviation plug 8 is electrically connected to the BMS protection board 1.

[0048] During assembly, first fix the BMS protection board 1 on the inner wall of the main chassis body 2, then install the battery module 5 into the main chassis body 2 and fix it. Then, use wires to establish connections between the multiple sets of plugs and the BMS protection board 1 and the battery module 5. Finally, sleeving and fixing the encapsulation board 3 on the main chassis body 2 can complete the assembly of this lithium battery power supply; installing this lithium battery power supply at the designated position of the mine cage through the fixed feet 202 can supply energy for the operation of the mine cage.

[0049] The lithium battery power supply for the mine cage of the present utility model is flexible and convenient to install and use, convenient for maintenance, has a high integration level, can greatly improve the installation efficiency, make full use of space, can be used according to different usage scenarios of customers, increase the selectivity of users, and is more suitable for use with multiple models of lithium battery modules;

[0050] Through the edge sealing component, it can automatically seal the gap between the main chassis body 2 and the encapsulation board 3 after installation, improve the protection effect of the chassis on the battery module 5, and is beneficial to extending the service life of the battery module 5.
