Description

Technical Field

[0001] The invention relates to the technical field of lithium battery cells, in particular to a new type of lithium battery for starting a heavy truck and for backing up parking air conditioners. Background Art

[0002] Parking air conditioners are currently mainly installed on heavy trucks. Heavy trucks are further divided into tractors, dump trucks and engineering trucks. Among them, tractors have grown significantly in recent years with the rapid development of long-distance logistics transportation. All of these have directly promoted the rapid development of the parking air conditioner supporting market. This allows heavy trucks to install parking air conditioners and use them with lithium batteries, mainly lithium iron phosphate batteries. Lithium iron phosphate batteries have the characteristics of high energy density, long life and excellent safety performance, making them an ideal choice for heavy truck electrical systems. On the one hand, as a starting power source, it can provide stable and sufficient power when the truck starts, ensuring that the engine starts smoothly. On the other hand, it can also provide backup power for the parking air conditioner. When the vehicle is turned off or the generator cannot supply power, the lithium battery can continue to power the parking air conditioner, ensuring that the driver can still enjoy a comfortable driving environment when resting.

[0003] For example, the patent application number of the China Patent Network is: 202220241684.4, which discloses a battery cell protection box for a pure electric heavy-duty truck, which relates to the field of heavy-duty truck battery cell technology. The battery cell protection box for a pure electric heavy-duty truck includes a box body, a splint, a clamping mechanism and a heat dissipation component. A blocking cover is provided on the top of the box body, and a partition is fixedly installed inside the box body. The number of splints is two groups and they are all arranged on the top of the partition, and a limited space is formed between the two groups of splints. The battery cell protection box for a pure electric heavy-duty truck has a good buffering effect when clamping and contacting the outer wall of the battery cell, avoiding the situation where the outer wall of the battery cell is damaged by sudden tightening, and relatively improving the practicality of the protection box. It is also suitable for use with batteries of different sizes, and the shape of the box body can effectively divert rainwater, thereby avoiding the soaking of the battery cell caused by rainwater intruding into the box body, and will not affect the heat dissipation of the battery cell.

[0004] In the daily operation of heavy trucks, the engine start and the continuous operation of the parking air conditioner rely on lithium batteries. However, the traditional battery uses four screws at the four corners to fasten the battery cover, which is not only cumbersome to install manually, but also easy to loosen the screws due to long-term driving vibration, which allows rain or dust to penetrate into the battery shell. In addition, when used in northern regions, although the battery is equipped with a heating device for thermal management, the severe cold weather will still increase power consumption when the vehicle is parked for a long time, resulting in energy waste.

[0005] Therefore, it is necessary to design and modify the new lithium batteries used for starting heavy trucks and parking air conditioning backup power to effectively prevent the loosening of the battery cover and waste of electricity. Summary of the invention

The battery cell 2 is installed inside the cell shell 1, providing reliable power support for the truck. The cell cover 3 is tightly fixed to the top of the cell shell 1 through a fixing mechanism, ensuring the sealing inside the equipment. The fixing mechanism includes a fixing plate 4 fixedly connected to the left and right sides of the cell cover 3, and a connecting plate 5 is arranged at the bottom of the fixing plate 4, and the inner side of the connecting plate 5 is fixedly connected to the left and right sides of the cell shell 1. A plurality of screws 6 are arranged on the top of the fixing plate 4, and the bottoms of these screws 6 penetrate to the bottom of the connecting plate 5 and are threadedly connected to the inner wall thereof, thereby realizing the tight fixation of the cell cover 3 and the cell shell 1.

When the pool cover 3 needs to be opened or closed, only the worm 8 needs to be rotated, and the worm 8 will drive the worm wheel 7 to rotate, and then drive the screw 6 to rotate and lift, so as to open or close the pool cover 3. In addition, the support plate 10 can also slide outward on the surface of the support block 9, driving the worm 8 to break away from the contact with the worm wheel 7, thereby switching the linkage and single-action capabilities of the screw 6 to meet the use requirements in different scenarios.
