Technical Field

[0001] The present invention relates to the technical field of lithium batteries, and specifically to a special lithium battery pack for the parking air conditioner of large trucks. Background Art

[0002] A special lithium battery pack for the parking air conditioner of large trucks is a lithium battery pack specifically designed for the parking air conditioner system of large trucks. Lithium batteries have a relatively high energy density and can store more energy in a smaller volume and weight, making them suitable for application scenarios such as large trucks that have requirements for space and weight. When the large truck is parked and resting, it provides power support for the parking air conditioner, enabling the driver to rest in a comfortable environment and improving work efficiency and quality of life. In addition to the parking air conditioner, it can also provide power for other in-vehicle devices such as refrigerators, TVs, and stereos, meeting the diverse power consumption needs of the driver during long-distance transportation.

[0003] When a large truck is driving, it often enters different environments. As the road crosses large areas, the climate environment will change, with hot or cold weather. However, traditional lithium battery packs lack temperature control adjustment, resulting in instability during use. Specifically, in hot weather, the temperature may be too high and heat dissipation may be insufficient, while in cold weather, the power consumption of the lithium battery pack will increase. When the lithium battery components are used in an unstable environment for a long time, the probability of damage increases, which easily affects their service life.

DETAILED DESCRIPTION OF THE INVENTION

[0019] The technical solution in the embodiment of the present application is to solve the problems in the above-mentioned background technology, and the general idea is as follows: During use, the temperature of the battery module 9 can be regulated to a constant temperature, which can enhance the comfort of the usage environment of the battery module 9, thereby realizing the protection of the battery module 9 and improving the service life; mainly by providing ventilation openings 12 in the middle of both ends of the protection box 7, and providing a sealing plate 13 in the ventilation opening 12, the sealing plate 13 is adjusted by a driving component, and in cooperation with the detection of temperature by a temperature sensor, the opening degree of the ventilation opening 12 can be adjusted, and then in cooperation with the flexible regulation of the heat dissipation component, the temperature inside the protection box 7 can be intelligently regulated; In addition, the setting of the shock absorption component enables the battery module 9 to enhance the stability of the large truck when driving on different road conditions and reduce the shaking of the battery module 9. Moreover, the setting of the sliding component facilitates the disassembly and assembly of the protection box 7, thereby providing convenience for the maintenance work of the staff on the battery module 9 inside the protection box 7.

[0020] Example 1: Refer to Figure 1 - Figure 5 As shown, a special lithium battery pack for a large truck parking air conditioner in this embodiment includes a fixing frame 1. The middle part inside the fixing frame 1 is provided with an installation box 2. The middle part inside the installation box 2 is provided with a protection box 7. Two groups of battery modules 9 are respectively arranged in the middle part inside the protection box 7 in an upper and a lower layer. The battery module 9 is composed of multiple groups of lithium batteries arranged side by side. The protection box 7 mainly plays a role in sealing and protecting the battery module 9.

[0021] A heat dissipation component, which includes ventilation openings 12 provided at both ends of the protection box 7. Multiple groups of sealing plates 13 are provided in the middle part inside the ventilation openings 12. The multiple groups of sealing plates 13 are movably installed in the middle part inside the ventilation openings 12 and are driven to rotate by a driving component. The multiple groups of sealing plates 13 are used to open or close the ventilation openings 12; the driving component includes two groups of racks 16. The two groups of racks 16 are respectively installed at the upper and lower ends of the sealing plate 13. Rotating gears 15 are provided at both the upper and lower ends of the sealing plate 13. The rotating gears 15 are movably installed at the upper and lower ends of the ventilation opening 12 and are respectively meshed with the racks 16. The two groups of racks 16 are respectively movable at the upper and lower ends of the ventilation opening 12 and are driven to slide synchronously by a driving motor 17. The right ends of the two groups of racks 16 are respectively meshed with a driving gear 18. The two groups of driving gears 18 are fixedly connected by a rotating shaft 19. The driving motor 17 is installed at the top of the rotating shaft 19.

[0022] The heat dissipation component further includes multiple groups of fans 10 and an air inlet pipe 20. The air inlet pipe 20 is connected to a cold air blower through a pipeline.

[0023] Among them, the arrangement of the driving component and the sealing plate 13 makes it possible to intelligently adjust the opening size of the vent 12. When it is necessary to dissipate heat for the battery module 9 in the protective box 7, first start the driving motor 17 of the driving component. The driving motor 17 can drive two sets of driving gears 18 to rotate, and the driving gear 18 can drive the rack 16 to move horizontally, thereby driving multiple sets of rotating gears 15 to rotate. The rotating gear 15 rotates, which can drive the sealing plate 13 to rotate, thereby forming an open state. When the sealing plate 13 rotates 90 degrees, it is in a fully open state, and the vents 12 at both ends of the protective box 7 can be ventilated to the maximum. At this time, the fan 10 that opens the ventilation channel 11 is blown to make the airflow inside the ventilation channel 11 in a smooth state, thereby playing a role in ventilation and heat dissipation. In addition, by adjusting the rotation angle of the sealing plate 13 and cooperating with the temperature sensor to detect the temperature, the opening size of the vent 12 can be adjusted to achieve intelligent adjustment of the temperature in the protective box 7.

[0024] In addition, the inlet end of the air inlet duct 20 is connected to an air cooler through a pipeline. When the heat dissipation effect of the fan 10 is not good, the vent 12 can be completely covered and sealed by rotating the sealing plate 13, and then the air cooler at the inlet end of the air inlet duct 20 is turned on to deliver cold air into the protective box 7, and then blown by multiple groups of fans 10, so that the cold air can flow in the protective box 7, so that the cold air evenly covers every angle in the protective box 7, thereby achieving uniform cooling of the battery module 9, thereby effectively improving the efficiency and quality of cooling.

[0025] In some examples, ventilation channels 11 are reserved between two groups of battery modules 9 and between the battery module 9 and the inner wall of the protective box 7 ; the fan 10 is located on the inner side of the vent 12 and installed at the head end of the ventilation channel 11 .

[0026] In some examples, both ends of the sealing plate 13 are fixedly connected to the rotating gear 15 via a connecting shaft 14 .

[0027] Example 2: Reference Figure 1 - Figure 5 As shown, based on Example 1, a lithium battery pack dedicated to a parking air conditioner for a large truck also includes the following structure: The shock absorbing assembly includes multiple groups of shock absorbers 3 and limit assemblies. The limit assemblies include multiple groups of limit sleeves 4 and multiple groups of limit slide bars 5. The multiple groups of limit slide bars 5 are respectively fixedly installed at the middle of both ends of the fixing frame 1, and the multiple groups of limit sleeves 4 are respectively fixedly installed at the middle of both ends of the installation box 2. The limit slide bars 5 are slidably connected with the limit sleeves 4 to play a role of limiting. The shock absorbing assembly mainly plays a role of shock absorption, enhances the stability of the battery module 9 when following the large truck on the road, and reduces the shaking of the battery module 9.

[0028] In some examples, a sliding assembly is provided in the middle of the bottom end of the protective box 7. The sliding assembly includes two groups of limit slide rails 6 and two groups of limit sliders 8. Both groups of limit slide rails 6 are fixedly installed at the inner bottom of the installation box 2, and both groups of limit sliders 8 are fixedly installed at the bottom of the protective box 7. The limit sliders 8 are slidably installed in the middle of the upper end of the limit slide rails 6 and are limited and locked by multiple groups of fixing bolts.

[0029] Among them, the limit slider 8 slides horizontally on the limit slide rail 6, so as to facilitate the staff to quickly disassemble and assemble the protective box 7.

[0030] In some examples, multiple shock absorbers 3 are evenly distributed at the bottom of the installation box 2.

[0031] The working principle of the present invention is: In the present invention, ventilation openings 12 are provided in the middle of both ends of the protective box 7, and sealing plates 13 are provided in the ventilation openings 12. The sealing plates 13 are adjusted by a driving assembly, and in cooperation with the detection of temperature by a temperature sensor, the opening degree of the ventilation openings 12 can be adjusted, so as to realize intelligent adjustment of the temperature inside the protective box 7.

[0032] When in use in severe cold weather, the ventilation openings 12 are covered and sealed by closing the sealing plates 13, which plays a role in heat preservation and avoids the battery module 9 from consuming electricity too quickly due to cold. When the internal temperature is relatively high, by opening the sealing plates 13, the ventilation openings 12 are ventilated, and at the same time, the fan 10 blows air into the ventilation channel 11, which plays a role in ventilation and heat dissipation.

[0033] In addition, an air inlet pipe 20 is also provided at the top of the protective box 7. The air inlet pipe 20 is connected to a cold air blower. When the large truck is in a hot area and it is difficult for the fan 10 to dissipate heat, at this time, the sealing plates 13 are closed to make the inside of the protective box 7 in a sealed state, and at the same time, the cold air blower connected to the air inlet pipe 20 is turned on, and cold air is conveyed into the protective box 7, so as to effectively enhance the cooling effect and protect the battery module 9 from overheating. Through the above structure, the temperature inside the protective box 7 can be adjusted in real time and kept constant, and the comfort of the use environment of the battery module 9 is enhanced.

[0034] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and the descriptions in the specification only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
