Detailed Description

The following detailed description of embodiments of the utility model is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the utility model is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or components.

As shown in fig. 1 to 6, a lithium battery pack for an electric vehicle according to an embodiment of the present utility model includes a lithium battery pack case 2, a mounting frame 1 is provided on the electric vehicle, the lithium battery pack case 2 is mounted in the mounting frame 1, and a plurality of battery cells 3 are provided in the lithium battery pack case 2.

Referring to fig. 3, the bottom of the installation frame 1 is connected with a collection box 4 in a threaded manner, the collection box 4 penetrates through the side walls of the installation frame 1 and the lithium battery pack shell 2, external threads are formed at the upper end of the collection box 4, internal threads matched with the external threads are formed in the installation frame 1, and the collection box 4 is convenient to install and detach.

Further, when the temperature of the battery cell 3 inside the lithium battery pack case 2 is high, the collection box 4 can be screwed, and the collection box 4 is detached from the mounting frame 1. Namely, the inside of the lithium battery pack shell 2 can be better contacted with air, and the heat generated by the battery cell 3 can be rapidly emitted.

Especially in hot summer, after the electric vehicle is driven for a period of time, the temperature of the battery cell 3 is higher, at the moment, the collecting box 4 can be detached, the interior of the lithium battery pack shell 2 is enabled to circulate with outside air, and when the temperature of the battery cell 3 is reduced, the collecting box 4 can be connected in the mounting frame 1 in a threaded mode.

Meanwhile, when the collecting box 4 is not used, the corresponding plug can be used for plugging the threaded hole of the mounting frame 1, so that dust is prevented from entering the lithium battery pack shell 2 through the threaded hole formed in the mounting frame 1 and the through hole formed in the lithium battery pack shell 2, and the use of the battery cell 3 is prevented from being influenced.

The collecting box 4 is communicated with the space inside the lithium battery pack shell 2, a mounting hole is formed in the collecting box 4, an observation plate 5 is fixedly connected in the mounting hole, and the observation plate 5 can be adhered in the mounting hole.

Specifically, the mounting frame 1 is specially used for placing a lithium battery pack and is arranged on the electric vehicle, the collecting box 4 is positioned at the bottom of the electric vehicle, and meanwhile, the normal running of the electric vehicle is not affected by the height of the collecting box 4, and the mounting frame is specifically shown in fig. 6.

When rainwater enters the lithium battery pack shell 2, the rainwater flows downwards and falls into the collecting box 4 under the action of gravity, and the observing plate 5 is a transparent acrylic plate, namely whether liquid exists in the collecting box 4 or not can be observed through the observing plate 5. I.e. when a rupture of the lithium battery pack case 2 occurs, rainwater or other liquid can enter the lithium battery pack case 2 through the rupture and then flow into the collecting box 4.

Referring to fig. 2 and 4, a shaft lever 10 is fixedly connected to the bottom of the collecting box 4, a connecting plate 9 is rotatably connected to the shaft lever 10, and a wiping block 12 matched with the collecting box 4 is fixedly connected to the connecting plate 9. The wipe block 12 is a brush or wipe. That is, when the connecting plate 9 is rotated, the connecting plate 9 drives the wiping block 12 to rotate, so that the surface of the observation plate 5 can be wiped, dust on the surface of the observation plate 5 is wiped off, and the dust is prevented from adhering to the observation plate 5, so that observation is affected.

Referring to fig. 3, a main collecting rope 6 is arranged in the lithium battery pack casing 2, a plurality of auxiliary collecting ropes 7 are fixedly connected to the main collecting rope 6, and the tail end of the main collecting rope 6 is positioned in the collecting box 4. The main collecting rope 6 and the auxiliary collecting rope 7 are cotton ropes.

I.e. rainwater enters the lithium battery pack case 2, the liquid may fall on the lower cell 3, thereby adhering to the cell 3 and not flowing into the collection box 4. When the liquid falls on the lower cell 3, the liquid may infiltrate into the cell 3, which affects the normal use of the cell 3.

Rainwater can be absorbed through the main collecting rope 6 and the auxiliary collecting rope 7, so that the rainwater can not fall on the battery cell 3 below, and meanwhile, the rainwater can flow into the collecting box 4 along the auxiliary collecting rope 7 and the main collecting rope 6.

Referring to fig. 4, a plurality of heat dissipation fins 11 are fixedly connected to the collection box 4. Since the collection box 4 communicates with the inside of the lithium battery pack case 2. Namely, heat generated by the battery cell 3 in the lithium battery pack shell 2 flows into the collecting box 4, and the heat in the collecting box 4 can be dissipated into the air through the radiating fins 11, so that the radiating effect on the lithium battery pack is achieved.

The bottom of the collecting box 4 is provided with a flow hole, and a plug 8 is inserted in the flow hole. When the plug 8 is pulled out, rainwater can flow out of the collecting box 4 through the flowing hole, so that cleaning is facilitated.

When the lithium battery pack is used, as shown in fig. 1-6, when rainwater enters the lithium battery pack shell 2, the rainwater can fall into the collecting box 4, whether the collecting box 4 is internally provided with the rainwater can be observed through the observing plate 5, and the lithium battery pack can be cleaned in time and maintained conveniently. When the rainwater falls on the main collecting rope 6 and the auxiliary collecting rope 7, the rainwater can flow into the collecting box 4 along the main collecting rope 6 and the auxiliary collecting rope 7, so that the rainwater can be conveniently collected.

Compared with the prior art, according to the lithium battery pack for the electric vehicle, when rainwater enters the lithium battery pack, the rainwater can be intuitively observed and collected, so that the rainwater is not easy to contact with the battery cell for a long time, and the battery cell is not easy to damage.
