[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] 1. By assembling the battery module and the cooling module on the carrier module, wherein the cooling module is composed of a liquid cooling mechanism and an air cooling mechanism, the cooling module can perform dual cooling treatments of liquid cooling and air cooling on the battery module, thereby improving the cooling efficiency of the battery module, making the battery module in a relatively safe use environment, ensuring its service life, avoiding the occurrence of spontaneous combustion of the battery module due to high temperature, and further ensuring the safety of battery use.

[0027] 2. The liquid cooling and air cooling in the cooling module are driven by the driving mechanism. According to the ambient temperature of the battery module when in use, the motor in the driving mechanism is rotated forward and reversely to select the synchronous use of liquid cooling and air cooling, thereby ensuring that the battery module is in a relatively safe use environment, avoiding problems caused by excessively high temperatures in the use environment, and reducing the service life and endurance of the product due to excessively low temperatures in the use environment.

[0028] 3. When the ambient temperature of the battery module is normal, the motor in the drive mechanism rotates forward. At this time, the blower assembly in the air cooling mechanism does not move accordingly. The drive mechanism can only drive the liquid cooling mechanism to cool the battery module to prevent the temperature of the battery module from being too low. When the ambient temperature of the battery module is too high, the motor in the drive mechanism reverses. At this time, the blower assembly in the air cooling mechanism moves accordingly to achieve a blowing effect. The airflows driven by the blower assemblies on both sides are released after passing through the corresponding air ducts, thereby achieving convection blowing on the battery module, thereby further improving the cooling efficiency of the battery module.

[0029] 4. The cells in each battery pack in the battery module are isolated by a heat-conducting plate, and then bundled with a restraint sleeve to form an integral structure. The restraint sleeve is provided with a side plate for heat conduction. The side plate is in contact with each heat-conducting plate, thereby transmitting the heat emitted by each cell. Finally, the heat dissipation effect of the battery module is achieved through the liquid flowing in the serpentine heat pipe located on the side plate. Among them, the outer surface of each heat-conducting plate adopts a concave-convex design, and a notch is opened on the side plate, so as to facilitate the passage of airflow during air cooling treatment and ensure efficient heat dissipation of the battery module.

[0030] 5. When the carrier module is assembling the battery module, the battery pack in the battery module is connected in series through the horizontal bar, and then the horizontal bar and the carrier are fixed with the help of the threaded rod group to complete the constrained assembly of the battery module. The disassembly and assembly operation is convenient, which facilitates the maintenance and processing, and reduces the operating burden of the maintenance personnel.

The connection between the frame 4312 and the two push-pull rods 436 is achieved through the connecting plate 437, so that the stability of the position of the frame 4312 is not only guaranteed, but also the two push-pull rods 436 can be synchronized when the frame 4312 is displaced.

[0069] The driving mechanism 44 includes a motor 441 disposed on the top shell wall of the U-shaped frame 41. A rotating shaft is installed at the output end of the motor 441, and the top end of the rotating shaft passes through the liquid storage tank 431 and the column 432, and is fixedly connected to the disc 4311. The arrangement of the column 432 ensures that the rotating shaft will not come into contact with the liquid inside the liquid storage tank 431 when passing through the liquid storage tank 431.

[0070] A driving bevel gear 442 is mounted on the rotating shaft below the liquid cooling mechanism 43, and driven bevel gears 443 meshing therewith are disposed on both sides of the driving bevel gear 442. When the driven bevel gears 443 at both sides move with the driving bevel gear 442, the two driven bevel gears 443 rotate in opposite directions.

[0071] A transmission shaft 444 is installed on the side of the driven bevel gear 443 away from the driving bevel gear 442. One end of the transmission shaft 444 away from the driven bevel gear 443 is connected to the corresponding air cooling mechanism 42 through a coupling 445. When the driven bevel gear 443 moves, the operation of the air blowing assembly 423 in the corresponding air cooling mechanism 42 is realized through the cooperation of the transmission shaft 444 and the corresponding coupling 445.

[0072] Two support plates are sleeved on each transmission shaft 444 , and the bottom of the support plates is fixedly connected to the U-shaped frame 41 .

[0073] See also Figure 4-Figure 6 In the embodiment of the present invention, the cells 31 in the battery module 3 are connected in series through the conductive sheet on the insulating plate 5, and the insulating plate 5 is connected to the battery management system 6 through the conductive sheet. The positive and negative electrodes of each cell 31 are both located at the top, and then the insulating plate 5 realizes the series connection of each cell 31 through the conductive sheet arranged thereon.

[0074] The working principle of the present invention is: when the product is in use, the battery management system 6 first turns on the semiconductor cooling plate 433 in the liquid cooling mechanism 43 in the cooling module 4, and then realizes cooling of the liquid in the liquid storage tank 431.

[0075] When the temperature sensor in the housing 1 detects that the temperature inside the housing 1 reaches the point where liquid cooling is required, the battery management system 6 in the housing 1 turns on the driving mechanism 44 in the cooling module 4. At this time, the motor 441 in the driving mechanism 44 rotates forward, driving the active bevel gear 442 and the disc 4311 in the liquid cooling mechanism 43 to move through the rotating shaft.

[0076] During the movement of the disc 4311, the frame 4312 connected thereto moves back and forth. During the movement of the frame 4312, the corresponding push-pull rods 436 are driven to move synchronously through the connecting plate 437. Each push-pull rod 436 drives the movable plug 435 loaded thereon to move along with the movement of the frame 4312.

[0077] When each movable plug 435 moves in the corresponding liquid pumping cylinder 434, if the movable plug 435 in the front liquid pumping cylinder 434 moves forward, at this time, the movable plug 435 generates thrust during the movement, and pushes the liquid stored in the liquid pumping cylinder 434. The liquid enters the corresponding liquid pumping tube 438 under the action of the pushing of the movable plug 435, but due to the one-way valve 1 provided on the liquid pumping tube 438, the liquid can only enter the infusion tube 439 on the liquid pumping tube 438. Under the action of the thrust, the liquid passes through the one-way valve 2 on the infusion tube 439 and enters the serpentine heat pipe 35 on the corresponding battery pack in the battery module 3. The liquid in the serpentine heat pipe 35 pushes the original liquid when the new liquid enters, and the original liquid enters the liquid storage tank 431 under the action of the corresponding reflux pipe 4310 and mixes with the original liquid in the liquid storage tank 431. The semiconductor cooling sheet 433 disposed in the liquid storage tank 431 cools the liquid in the liquid storage tank 431. The liquid in the serpentine heat dissipation pipe 35 carries the heat on the upper side plate 34 of the battery pack during the flow, thereby achieving a cooling effect on the battery pack.

[0078] When the active plug 435 in the front side liquid pumping cylinder 434 moves forward, at this moment, the active plug 435 in the rear side liquid pumping cylinder 434 also moves forward synchronously. However, since the rear side liquid pumping cylinder 434 is arranged in the opposite direction to the front side liquid pumping cylinder 434, the active plug 435 in the rear side liquid pumping cylinder 434 realizes the suction effect of the liquid pumping cylinder 434 during the forward movement. At this moment, the liquid pumping tube 438 on the rear side liquid pumping cylinder 434 extracts and stores the liquid that has been refrigerated in the liquid storage tank 431. After the front side liquid pumping cylinder 434 completes the pushing of the liquid, the rear side liquid pumping cylinder 434 then completes the extraction and storage of the liquid.

[0079] Then, as the disc 4311 moves, the frame 4312 moves backward, and at this time, the movable plugs 435 in each liquid pumping cylinder 434 move backward synchronously. The liquid in the rear liquid pumping cylinder 434 is pushed out and enters the serpentine heat dissipation pipe 35 of the corresponding battery pack under the action of the corresponding infusion pipe 439 and the one-way valve 2. Then the original liquid in the serpentine heat dissipation pipe 35 flows into the liquid storage tank 431 through the corresponding reflux pipe 4310. The movement of the disc 4311 causes the frame 4312 to reciprocate, and then the liquid pumping cylinders 434 arranged in front and behind circulate the above steps, thereby realizing the flow of liquid in the corresponding serpentine heat dissipation pipe 35, and realizing the liquid cooling treatment of the battery module 3.

[0080] At this time, since the motor 441 is in a forward rotation state, the driving bevel gear 442 also rotates forward. When the driving bevel gear 442 rotates forward, the driven bevel gears 443 on both sides thereof meshing with it move synchronously. However, the driven bevel gear 443 on the left side moves counterclockwise, while the driven bevel gear 443 on the right side moves clockwise. When the driven bevel gears 443 on both sides rotate, they drive the corresponding transmission shafts 444 to move, and then the corresponding couplings 445 are used to make the air blowing assembly 423 in the air cooling mechanism 42 connected thereto move.

[0081] The transmission shaft 444 is connected to the driving shaft 4234 in the corresponding air blowing assembly 423 through the coupling 445, thereby causing the corresponding moving disk 4233 to rotate.

[0082] Since the transmission directions of the two driven bevel gears 443 are different, the air blast assemblies 423 in the air cooling mechanism 42 on both sides of the U-shaped frame 41 are also different. The moving disk 4233 in the left air blast assembly 423 is in an idling state when moving counterclockwise, and will not drive the corresponding end disk 4232 to move, while the moving disk 4233 in the right air blast assembly 423 is also in an idling state when moving clockwise, and will not drive the corresponding end disk 4232 to move. The sub-frame 4237 and the corresponding movable plate 4238 provided in each air blast assembly 423 prevent the end disk 4232 from moving due to friction when the corresponding moving disk 4233 is idling, thereby preventing the rotating shaft from driving the rotating blades to move, and avoiding the occurrence of air cooling.

[0083] When the temperature sensor in the housing 1 detects that the temperature inside the housing 1 has reached the point where liquid cooling and air cooling are required for simultaneous heat dissipation, the battery management system 6 in the housing 1 controls the motor 441 of the drive mechanism 44 in the cooling module 4 to reverse operation. At this time, when the motor 441 is running, the shaft mounted thereon drives the liquid cooling mechanism 43 to continue to operate, while the driving bevel gear 442 on the shaft moves in the opposite direction. At this time, the two driven bevel gears 443 meshing therewith move in the opposite direction again, the driven bevel gear 443 on the left moves clockwise, and the driven bevel gear 443 on the right moves counterclockwise.

[0084] When the two driven bevel gears 443 move in opposite directions, the driven bevel gear 443 on the left side makes the drive shaft 4234 in the corresponding blower assembly 423 move clockwise through the corresponding transmission shaft 444 and the coupling 445. The driven bevel gear 443 on the right side makes the drive shaft 4234 in the corresponding blower assembly 423 move counterclockwise through the corresponding transmission shaft 444 and the coupling 445.

[0085] At this time, when the moving disk 4233 in the left blower assembly 423 moves clockwise, the swing arm 4235 thereon engages with the slot in the corresponding end disk 4232, thereby driving the corresponding rotating shaft to rotate. The blower assembly 423 on the right is similar to the blower assembly 423 on the left. When the rotating shafts in the two blower assemblies 423 move, the rotating blades installed thereon move, thereby forming an airflow to blow toward the corresponding air duct 421, and the airflow is transported along the air duct 421, and then released at the corresponding wind cover 422, thereby air cooling the corresponding battery pack in the battery module 3.

[0086] By combining air cooling and liquid cooling, efficient cooling of the battery module 3 is achieved.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
