Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery packs, and specifically to a lithium battery pack structure with a waterproof function. Background Technique

[0002] A lithium battery pack is a relatively commonly used energy storage battery. When in use, people often move it outdoors to supply power to some devices placed outdoors. A lithium battery is a type of battery with lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high requirements for the environment. With the development of science and technology, lithium batteries have become the mainstream. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium-ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. The fifth-generation product of rechargeable batteries, the lithium metal battery, was born in 1996. Its safety, specific capacity, self-discharge rate, and performance-price ratio are all superior to those of lithium-ion batteries; due to its own high-tech requirements, only companies in a few countries produce this kind of lithium metal battery.

[0003] Most existing lithium battery packs do not have a waterproof mechanism when stored, so they do not have a waterproof function. When encountering rainy weather, people need to move the lithium battery pack to a place without rain to prevent rain from entering the lithium battery pack. Moving the lithium battery pack is quite laborious, which is not convenient for people to place it outdoors for use and is difficult to provide safety protection. Therefore, corresponding technical solutions need to be designed to solve this problem. Summary of the Invention

[0049] Specifically improved, heat sinks 26 are distributed through the front and rear of the cover plate 2. A heat-conducting copper plate 262 is fixed at the bottom of the heat sink 26. Heat-conducting density copper tubes 261 are connected between both ends of the heat-conducting copper plate 262 and the pressing plate 27.

[0050] The heat-conducting density copper tube 261 is used to conduct the heat of the pressing plate 27 to the heat-conducting copper plate 262. The heat-conducting copper plate 262 is used to disperse the heat to a plurality of heat sinks 26. The heat sinks 26 extend outside the cover plate 2 to dissipate heat.

[0051] Working principle: Place the lithium battery pack inside the lithium battery pack box 1. Through the elastic action of the first spring 172, the clamping plate 17 clamps and positions the lithium battery pack front and back.

[0052] Hold the extension rod 156 and rotate the turntable 155, so that the adjusting rod 153 moves inward through the action of the thread inside the limiting cylinder 154. Clamp and hold both sides of the lithium battery pack firmly through the clamping plate 152 to prevent it from shaking and shifting.

[0053] Insert the power cord of the lithium battery pack into the power interface 111. Place the lithium battery pack box 1 stably through the cushion block 13. Supply power to an external power device through the power output port 11 for use.

[0054] After closing the cover plate 2, it is clamped above the sealing support plate 122 and the sealing rubber ring 123 through the sealing ring plate 21 and the inner ring plate 211 to seal and prevent water ingress, avoiding rainwater from entering. The movable buckle plate 241 is buckled at the buckle groove 121 to fasten and close the cover plate 2 above the support end plate 12 of the lithium battery pack box 1;

[0055] The pressure plate 27 presses on the lithium battery pack through the high-elastic buffering of the spring three 271 and the spring four 272 to further stably press the lithium battery pack;

[0056] The heat of the lithium battery pack is led out to the heat-conducting copper plate 262 through the heat-conducting density copper tubes 261 connected to both sides of the pressure plate 27. The heat-conducting copper plate 262 disperses the heat to a plurality of heat sinks 26, effectively dissipating the heat to the outside of the cover plate 2, and at the same time enhancing the waterproof effect;

[0057] One hand presses above the baffle 254, and downward compresses the positioning column 252 and the fixing plate 256 through the elastic action of the spring two 253. The fixing plate 256 slides in the sliding groove 143, and the positioning column 252 passes through the jack 142. The other hand passes through the pulling groove 2561 to hold the fixing plate 256, rotates and adjusts the inner support groove 146 of the fixing plate 256 for internal support, and uses a screw to pass through the screw hole two 145, the screw hole three 2562 and the screw hole one 144 to lock the positioning column 252, thereby fastening and closing the cover plate 2, and the waterproof and dustproof effect is better.

[0058] The lithium battery pack box 1 of the present invention, power output port 11, power interface 111, support end plate 12, buckle groove 121, sealing support plate 122, sealing rubber ring 123, cushion block 13, lower positioning plate 14, reinforcement plate one 141, jack 142, sliding groove 143, screw hole one 144, screw hole two 145, support groove 146, side plate 15, support plate 151, clamping plate 152, adjusting rod 153, limiting cylinder 154, turntable 155, extension rod 156, reinforcement plate two 157, flipping support plate 16, clamping plate 17, sliding plate 171, spring one 172, cover plate 2, sealing ring plate 21, inner ring plate 211, flipping plate 22, lifting device 23, movable support plate 24, clamping plate 241, upper positioning plate 25, movable hole 2501, reinforcement plate three 251, positioning column 252, spring two 253, baffle 254, snap ring 2541, limiting ring 255, fixing plate 256, pulling groove 2561, screw hole three 2562, heat sink 26, heat-conducting density copper tube 261, heat-conducting copper plate 262, pressing plate 27, spring three 271, support block one 2711, support block two 2712, spring four 272. The components are all common standard parts or parts known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or obtained through conventional experimental methods. The problem solved by the present invention is that it does not have a waterproof function. When encountering rainy weather, personnel need to move the lithium battery pack to a place without rain to prevent rain from entering the lithium battery pack. It is rather laborious to move the lithium battery pack, which is not convenient for personnel to place it outdoors for use and is difficult to provide safety protection. Through the mutual combination of the above components, the present invention is fastened and connected conveniently after closing the cover plate 2 through the buckle groove 121 opened at both ends of the front bottom of the support end plate 12 and the clamping plate 241 rotatably connected between the movable support plates 24, so that the safety protection effect of the lithium battery pack is enhanced. Through the sealing support plate 122 fixed around the top of the support end plate 12, the sealing rubber ring 123 and the inner ring plate 211 fixed inside the sealing ring plate 21, it is convenient to seal and limit after closing the cover plate 2, and the waterproof effect is good, avoiding rain from entering the interior of the lithium battery pack box 1. The lifting device 23 welded in the middle of the top of the cover plate 2 facilitates directly taking, placing and carrying the lithium battery pack, and the disassembly and assembly combination is relatively simple.

[0059] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic features of the present invention, the present invention can be implemented in other specific forms.
