[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, so that the battery module is in a relatively safe use environment, ensuring its service life, and avoiding the occurrence of spontaneous combustion of the battery module due to high temperature, thereby further ensuring the safety of battery use.

[0027] 2. The liquid cooling and air cooling in the cooling module are both driven by the driving mechanism. According to the ambient temperature of the battery module when in use, the forward and reverse rotation of the motor in the driving mechanism is used 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, thereby achieving a blowing effect. The airflow blown by the blower assemblies on both sides passes through the corresponding air ducts and is released, thereby achieving convection blowing on the battery module, thereby further improving the cooling efficiency of the battery module.

[0029] 4. The battery 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 battery 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 notches are opened on the side plate to facilitate the passage of airflow during air cooling treatment, thereby ensuring efficient heat dissipation of the battery module.

[0030] 5. When assembling the battery module, the carrier module connects the battery pack in the battery module in series through the horizontal bar, and then uses the threaded rod group to fix the horizontal bar and the carrier plate to complete the constrained assembly of the battery module. The disassembly and assembly operation is convenient, and the maintenance is convenient, which reduces the operating burden of the maintenance personnel. BRIEF DESCRIPTION OF THE DRAWINGS

[0051] See also Figure 7 In this embodiment of the present invention, the carrier module 2 is composed of a carrier plate 21, a horizontal bar 22, and a threaded rod assembly 23. Two horizontal bars 22 and two threaded rod assemblies 23 are provided, symmetrically arranged on the carrier plate 21. These horizontal bars 22 and threaded rod assembly 23 are used to secure the battery modules 3. The combination of the horizontal bars 22 and threaded rod assembly 23 provides a tight fit for the battery modules 3, thereby ensuring stable assembly of the battery modules 3 on the carrier module 2.

[0052] See also Figure 4-Figure 7 and Figure 10In this embodiment of the present invention, the cooling module 4 includes a U-shaped frame 41 mounted on the bottom wall of the carrier plate 21. Air cooling mechanisms 42 are provided on both sides of the U-shaped frame 41, and a liquid cooling mechanism 43 is located above the U-shaped frame 41 and is located on the carrier plate 21. A drive mechanism 44, located on the U-shaped frame 41, is mounted directly below the liquid cooling mechanism 43.

By driving the air cooling mechanism 42 and the liquid cooling mechanism 43 through the drive mechanism 44, dual cooling of the battery module 3 is achieved, improving the cooling effect of the product.

[0053] See also Figure 1 and Figure 4-Figure 9 In this embodiment of the present invention, the bottom of the carrier plate 21 is placed on the symmetrical storage plate 12, and a slot is defined in the center of the carrier plate 21 for accommodating the liquid cooling mechanism 43. A threaded hole group is defined on both sides of the slot, located on the carrier plate 21. The threaded hole group includes four threaded holes arranged in a matrix. The threaded holes on the front side are linearly spaced, and the threaded holes on the rear side are also linearly spaced.

[0054] The horizontal bar 22 is composed of a square tube and a slide bar. Among them, the slide bar is integrally arranged on the bottom outer wall of the square tube, and a plurality of through holes that penetrate the slide bar are opened horizontally and linearly on the square tube, and the through holes correspond to the threaded holes one by one. The threaded rod group 23 is composed of four threaded rods, and the bottom ends of the four threaded rods respectively penetrate the corresponding through holes and are movably connected with the corresponding threaded holes. When loading the battery module 3, the carrier module 2 only needs to place the battery module 3 on the carrier plate 21, and then place the two horizontal bars 22 symmetrically on top of the battery module 3, and then connect the threaded holes on the carrier plate 21 with the threaded rods in the corresponding threaded rod group 23, so as to achieve stable loading of the battery module 3 on the carrier plate 21 by the horizontal bar 22.

[0055] See also Figure 4-Figure 9 In the embodiment of the present invention, the battery module 3 includes two battery packs, which are respectively located on the carrier plate 21 on both sides of the placement slot. Each battery pack includes a plurality of heat-conducting plates 32 distributed longitudinally and linearly, and a battery cell 31 is arranged between two adjacent heat-conducting plates 32. The plurality of heat-conducting plates 32 and the battery cell 31 together form a whole, and are bundled together by two restraint sleeves 33 to form a battery pack. The heat-conducting plates 32 fit together with the battery cell 31, and then the heat generated by the battery cell 31 when the battery module 3 is in use is conducted through the corresponding heat-conducting plates 32. The setting of the restraint sleeve 33 can not only facilitate the assembly of the battery pack, but also has a heat-conducting effect.

[0056] The side walls of the two restraining sleeves 33 are mounted with side panels 34, and serpentine heat pipes 35 are installed on the outer walls of the side panels 34. The side panels 34 also make contact with the heat conducting plates 32. Heat conducted by the heat conducting plates 32 and the restraining sleeves 33 is then transferred to the side panels 34, where it is cooled by the flow of liquid in the serpentine heat pipes 35.

[0057] Each heat conducting plate 32 has a sliding groove on its top shell wall to facilitate the serial connection of the sliders on the horizontal bar 22. Multiple grooves are longitudinally provided on the front and rear side walls of the heat conducting plate 32, forming a concave-convex surface structure. Multiple notches for airflow are longitudinally provided on the side panels 34, wherein the notches are offset from the serpentine heat pipes 35. Furthermore, during air cooling, airflow can flow through the concave grooves on each heat conducting plate 32 in the battery pack, and then pass through the notches on the side panels 34, thereby achieving convection cooling of the two battery packs.

[0058] See also Figure 6-Figure 7 and Figure 10-11 In this embodiment of the present invention, a U-shaped frame 41 is fixedly connected to the bottom outer wall of the carrier plate 21 via bolts. Grooves are defined on both sides of the U-shaped frame 41. The air cooling mechanism 42 includes an air duct 421 disposed within the grooves, with a hood 422 fixedly connected to the top of the duct 421. The bottom of the hood 422 is fixedly connected to the corresponding wall of the U-shaped frame 41, and a blower assembly 423 is mounted at the bottom end of the duct 421. The hood 422 centrally discharges the airflow in the duct 421, achieving efficient air cooling for the battery pack.

[0059] See also Figure 10-11 and Figure 15-16 In this embodiment of the present invention, the air blowing assembly 423 includes a ventilation frame 4231 fixedly connected to the end of the air duct 421 by bolts. The ventilation frame 4231 is integrally provided with a straight plate at the air inlet, and a hole is opened in the straight plate. A rotating shaft is rotatably connected to the hole through a bearing.

[0060] The end of the rotating shaft that extends into the ventilation frame 4231 is circumferentially equipped with multiple rotating blades. The outer end of the rotating shaft is fixedly connected to an end plate 4232. A rotating groove is defined on the side of the end plate 4232 facing away from the rotating shaft. A moving plate 4233 is rotatably connected to the rotating groove. An annular groove is defined on the sidewall of the rotating groove. A circular ring is rotatably connected to the annular groove. The side of the circular ring facing away from the rotating groove is fixedly connected to the moving plate 4233.

[0061] A drive shaft 4234 is fixedly connected to the outer wall of the moving disk 4233. The inner wall of the rotating trough is circumferentially provided with multiple retaining grooves. The outer wall of the moving disk 4233 is circumferentially provided with multiple receiving grooves, each of which is movably connected to a swing arm 4235 via a pin. The swing arm 4235 is connected to the inner wall of the receiving groove via a return spring, and the swing arm 4235 and the retaining groove are in movable contact. To ensure that the moving disks 4233 within them idle together or drive the corresponding end disks 4232 to rotate, the retaining grooves on the swing arms 4235 and the inner walls of the corresponding end disks 4232 of the blower assemblies 423 on both sides are oriented in opposite directions.

[0062] The outer circumferential wall of the end plate 4232 is integrally formed with a protrusion 4236. A sub-frame 4237 is located on the outer wall of the ventilation frame 4231, flanking the protrusion 4236. A loading slot is defined at the bottom of the sub-frame 4237. A movable plate 4238 is movably connected to the loading slot via a connecting pin. Auxiliary arms are fixedly connected to the side walls of the movable plate 4238. On the two sides of the blower assembly 423, the sub-frames 4237 are positioned in opposite directions, resulting in the auxiliary arms on each movable plate 4238 also being positioned in opposite directions. This prevents the end plate 4232 from rotating when the corresponding movable plate 4233 is idling. When the movable plate 4233 rotates the end plate 4232, the protrusion 4236 contacts the movable plate 4238, causing the movable plate 4238 to be moved, thereby facilitating the rotation of the end plate 4232.

The bottom end of the liquid extraction tube 438 penetrates the top wall of the liquid storage tank 431 and extends into the interior of the liquid storage tank 431. A one-way valve 1 is provided on the liquid extraction tube 438. The one-way valve 1 ensures that the liquid extraction tube 438 can extract liquid from the liquid storage tank 431, but liquid cannot be transferred from the liquid extraction tube 438 to the liquid storage tank 431.

[0066] Above the first check valve is a liquid delivery tube 439 located on the liquid extraction tube 438. The other end of the liquid delivery tube 439 is connected to the liquid inlet of the corresponding serpentine heat dissipation tube 35. A second check valve is also installed on the liquid delivery tube 439. The second check valve ensures that the liquid in the liquid extraction tube 438 is transported to the serpentine heat dissipation tube 35.

[0067] A return pipe 4310 is provided on the side of the liquid extraction pipe 438, located on the top wall of the liquid storage tank 431. The bottom end of the return pipe 4310 extends into the interior of the liquid storage tank 431, and the top end of the return pipe 4310 is mounted on the liquid outlet end of the corresponding serpentine heat dissipation pipe 35. The provision of the return pipe 4310 allows the liquid in the serpentine heat dissipation pipe 35 to flow back into the liquid storage tank 431 after the injection of new liquid, thus achieving liquid recycling.

[0068] A disc 4311 is positioned between the two pumping cylinders 434, above the liquid storage tank 431. A protruding rod is fixedly connected to the top of the disc 4311, to which a frame 4312 is movably connected. Two connecting plates 437, one end away from the corresponding push-pull rods 436, are fixedly connected to the corresponding side walls of the frame 4312. The connecting plates 437 connect the frame 4312 to the two push-pull rods 436, ensuring the stability of the frame 4312 and allowing the two push-pull rods 436 to move synchronously when the frame 4312 is displaced.

[0069] The drive mechanism 44 includes a motor 441 mounted on the top wall of the U-shaped frame 41. A rotating shaft is mounted on the output end of the motor 441. The top end of the rotating shaft passes through the liquid reservoir 431 and the column 432 and is fixedly connected to the disk 4311. The column 432 is positioned so that the rotating shaft does not come into contact with the liquid inside the liquid reservoir 431 when passing through it.

[0070] A driving bevel gear 442 is mounted on the rotating shaft below the liquid cooling mechanism 43. Driven bevel gears 443 mesh with each other on both sides of the driving bevel gear 442. When the driven bevel gears 443 on both sides move with the driving bevel gear 442, the two driven bevel gears 443 rotate in opposite directions.

[0071] A drive shaft 444 is mounted on the side of the driven bevel gear 443 that is away from the driving bevel gear 442. The end of the drive shaft 444 that is away from the driven bevel gear 443 is connected to the corresponding air cooling mechanism 42 via a coupling 445. The movement of the driven bevel gear 443 is achieved through the interaction of the drive shaft 444 and the corresponding coupling 445, which drives the air blower assembly 423 in the corresponding air cooling mechanism 42.

[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 this embodiment of the present invention, the individual cells 31 in the battery module 3 are connected in series via the conductive pads on the insulating plate 5, and the insulating plate 5 is connected to the battery management system 6 via the conductive pads. The positive and negative electrodes of each cell 31 are located at the top, and the insulating plate 5 connects the cells 31 in series via the conductive pads provided 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 refrigeration plate 433 in the liquid cooling mechanism 43 in the cooling module 4, thereby cooling 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 has reached a point where liquid cooling is required, the battery management system 6 in the housing 1 turns on the drive mechanism 44 in the cooling module 4. At this point, the motor 441 in the drive mechanism 44 rotates forward, driving the driving bevel gear 442 and the disk 4311 in the liquid cooling mechanism 43 through the rotating shaft.

[0076] The movement of the disc 4311 causes the frame 4312, which is movably connected to it, to move back and forth. The frame 4312, through the connecting plate 437, drives the corresponding push-pull rods 436 to move synchronously. Each push-pull rod 436, in turn, drives the movable plug 435 attached to it to move in conjunction with the movement of the frame 4312.

[0077] When each movable plug 435 is in motion in the corresponding liquid pumping cylinder 434, if the movable plug 435 in the front side liquid pumping cylinder 434 moves forward, at this moment, this movable plug 435 produces thrust in the process of motion, and pushes the liquid stored in this liquid pumping cylinder 434. Liquid enters the corresponding liquid pumping pipe 438 under the effect of the movable plug 435 pushing, but due to the one-way valve 1 that is provided on the liquid pumping pipe 438, and then liquid can only enter the infusion pipe 439 on this liquid pumping pipe 438. Liquid enters the serpentine heat pipe 35 on the corresponding battery pack in the battery module 3 through the one-way valve 2 on the infusion pipe 439 under the effect of thrust. The liquid in this serpentine heat pipe 35 pushes the original liquid when new liquid enters, and the original liquid enters the liquid storage tank 431 under the effect of the corresponding reflux pipe 4310 and mixes with the original liquid in the liquid storage tank 431. The semiconductor cooling plate 433 provided in the liquid storage tank 431 cools the liquid in the liquid storage tank 431. The liquid in the serpentine heat 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 movable plug 435 in the front side liquid pumping cylinder 434 moves forward, at this moment, the movable plug 435 in the rear side liquid pumping cylinder 434 also moves forward synchronously.But because the rear side liquid pumping cylinder 434 and the liquid pumping cylinder 434 of the front side are arranged in the opposite direction, and then at this moment, the movable plug 435 in the rear side liquid pumping cylinder 434 realizes the suction action of this liquid pumping cylinder 434 in the process of moving forward.At this moment, the liquid pumping pipe 438 on the rear side liquid pumping cylinder 434 extracts and stores the liquid through refrigeration treatment in the liquid storage tank 431.After the front side liquid pumping cylinder 434 completes the pushing of liquid, the liquid pumping cylinder 434 of the rear side then completes the extraction and storage of liquid.

[0079] Then, as the disc 4311 moves, the frame 4312 moves backward. 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 pipe 35 of the corresponding battery pack under the action of the corresponding infusion tube 439 and the second one-way valve. Then, the original liquid in the serpentine heat pipe 35 flows into the liquid storage tank 431 through the corresponding return pipe 4310. The movement of the disc 4311 causes the frame 4312 to reciprocate, thereby causing the front and rear liquid pumping cylinders 434 to cycle the above steps, thereby realizing the flow of liquid in the corresponding serpentine heat pipe 35 and achieving liquid cooling of the battery module 3.

[0080] At this time, since the motor 441 is rotating forward, the driving bevel gear 442 also rotates forward. As the driving bevel gear 442 rotates forward, the meshing driven bevel gears 443 on either side of 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. As these driven bevel gears 443 rotate, they drive the corresponding drive shafts 444, which then, through the corresponding couplings 445, activate the connected blower assembly 423 in the air cooling mechanism 42.

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

[0082] Because the two driven bevel gears 443 have different transmission directions, the air blast assemblies 423 in the air cooling mechanism 42 on both sides of the U-shaped frame 41 also differ. The moving disk 4233 in the left air blast assembly 423 is in an idling state when moving counterclockwise and does not drive the corresponding end disk 4232 to move. The moving disk 4233 in the right air blast assembly 423 is also in an idling state when moving clockwise and does not drive the corresponding end disk 4232 to move. The sub-frame 4237 and 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 a point where simultaneous liquid and air cooling is required, 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 direction. As the motor 441 operates, the shaft mounted on it drives the liquid cooling mechanism 43 to continue operating, while the driving bevel gear 442 on the shaft rotates in the opposite direction. At this point, the two meshing driven bevel gears 443 also reverse direction, with the left driven bevel gear 443 rotating clockwise and the right driven bevel gear 443 rotating counterclockwise.

[0084] When the two driven bevel gears 443 move in opposite directions, the left driven bevel gear 443 causes the drive shaft 4234 in the corresponding blower assembly 423 to move clockwise through the corresponding transmission shaft 444 and coupling 445. The right driven bevel gear 443 causes the drive shaft 4234 in the corresponding blower assembly 423 to move counterclockwise through the corresponding transmission shaft 444 and 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 right blower assembly 423 is similar to the left blower assembly 423. When the rotating shafts in the two blower assemblies 423 move, the rotating blades mounted thereon move, thereby forming an airflow that blows air toward the corresponding air duct 421. The airflow is transported along the air duct 421 and then released at the corresponding air cover 422, thereby 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, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
