Description

[0002] New energy vehicle power batteries inevitably generate significant heat during operation, and effective heat dissipation is crucial for ensuring their performance and safety. Currently, widely used battery boxes often feature cooling holes on the top and fans for forced air cooling.

DETAILED DESCRIPTION

[0019] In order to more clearly and completely illustrate the technical solution of the present invention, the present invention will be further described below with reference to the accompanying drawings. Example 1

[0020] like Figures 1-10 As shown, an embodiment of the present invention proposes a new energy vehicle battery box, including a battery box body 1, a cover plate 2, a battery body 4 and a mounting plate 26. The battery box body 1 serves as the main load-bearing structure for installing and protecting internal components. The cover plate 2 serves as a top protective component and also has a heat dissipation function. The battery body 4 serves as a core energy storage component to provide power for the vehicle. The mounting plate 26 serves as a support platform for the heat-conducting component.

The plywood 3 is used to fix and separate the battery body 4. The partition net facilitates air circulation. The battery body 4 is installed between the two groups of plywood 3 to ensure stability and heat dissipation space.

[0022] like Figure 5 as well as Figure 9 As shown, a heat dissipation net 5 is provided on the upper side of the cover plate 2, and the heat dissipation net 5 is used to discharge heat. The lower side of the cover plate 2 is slidingly connected with a slide plate 7, and the slide plate 7 serves as a movable baffle. The bottom of the cover plate 2 is fixedly connected with a limit plate 6, and the limit plate 6 is used to limit the moving range of the slide plate 7. The slide plate 7 is slidably connected between the cover plate 2 and the limit plate 6 to achieve controllable sliding. A heat dissipation hole 8 is provided on the outside of the slide plate 7, and the heat dissipation hole 8 is matched with the heat dissipation net 5 to adjust the ventilation volume. The outside of the battery box body 1 is fixedly connected with a drive motor 10, and the drive motor 10 serves as a power source. The outside of the drive motor 10 is fixedly connected with a mounting cover 11, and the mounting cover 11 is used to protect the motor. The output shaft of the drive motor 10 is fixedly connected with a rotating shaft 12, and the rotating shaft 12 is used to transmit power.

[0023] like Figure 2 as well as Figure 3 As shown, a translation mechanism is installed between the rotating shaft 12 and the rack 9. The translation mechanism is used to realize the conversion of linear motion. The translation mechanism includes a rack 9 and a gear 13. The rack 9 is fixedly connected to the bottom of the skateboard 7 and is used for linear motion. The gear 13 is fixedly connected to the outside of the rotating shaft 12, and the gear 13 is meshed with the rack 9 to realize the conversion from rotational motion to linear motion.

[0024] like Figure 9 as well as Figure 10 As shown, a heat dissipation mechanism is installed on the outside of the rotating shaft 12, and the heat dissipation mechanism is used for active heat dissipation. The heat dissipation mechanism includes a fixed cylinder 14 and a fan 15. The fixed cylinder 14 is fixedly connected to the outside of the rotating shaft 12, and the fixed cylinder 14 is located directly below the heat dissipation network 5, serving as a fan mounting base. The fan 15 is fixedly connected to the inner side of the fixed cylinder 14 for generating forced airflow. A power supply is installed on the inner side of the fixed cylinder 14 to supply power to the fan, and an electrical conductor is connected between the power supply and the fan 15 to realize power transmission.

[0025] like Figure 7 as well as Figure 8 As shown, a water seepage detection mechanism is installed on the outside of the battery box body 1, and the water seepage detection mechanism is used to monitor the water ingress. The water seepage detection mechanism includes a mounting box 16, a filter 17, a drain hole 18, a fixing box 19 and a liquid level sensor 20. The mounting box 16 is fixedly connected to the outside of the battery box body 1 as a water collecting container. The filter 17 is opened on the upper side of the mounting box 16 for filtering impurities.

The liquid level sensor 20 is fixedly connected to the inner side of the fixing box 19 for detecting the water level.

[0026] In this embodiment, when the battery box is installed inside the new energy vehicle and is running, the heat generated by the battery body 4 can be discharged through the heat dissipation system. After the fan 15 is started, the airflow generated by it will conduct the heat emitted by the battery body 4 outward through the heat dissipation holes 8 of the slide plate 7 and the heat dissipation net 5 of the cover plate 2, thereby achieving effective air cooling and heat dissipation. In heavy rainy weather, if water seepage inside the vehicle body causes the water level to rise above the filter screen 17 of the installation box 16, the water will be initially filtered through the filter screen 17 and then enter the fixing box 19. A small amount of seepage water will be directly discharged from the drainage hole 18 at the bottom of the fixing box 19. At this time, the liquid level sensor The sensor 20 will not be triggered. If water continues to enter for a long time, the liquid level in the fixed box 19 will continue to rise to the set threshold, and the liquid level sensor 20 will be triggered. At this time, the PLC processor 40 controls the drive motor 10 to operate, and the drive motor 10 drives the rotating shaft 12 to rotate. Through the engagement transmission of the gear 13 and the rack 9, the slide plate 7 is forced to slide under the constraint of the limit plate 6, so that the heat dissipation hole 8 and the heat dissipation net 5 are completely misaligned, thereby closing the opening of the heat dissipation net 5. This can prevent external rainwater from invading the interior of the battery box body 1, protect the battery body 4 from water damage, and significantly improve the safety of battery use. Example 2

[0027] like Figures 1-13 As shown, based on the first embodiment, a water tank 21 is fixedly connected to the bottom of the battery box body 1, and the water tank 21 is used to store a cooling medium. A refrigerator 22 is fixedly connected to both sides of the water tank 21, and the refrigerator 22 is used to reduce the water temperature. The hot end of the refrigerator 22 is located outside the water tank 21 for heat dissipation, and the cold end of the refrigerator 22 is located inside the water tank 21 for cooling.

[0028] In this embodiment, water is used as the cooling medium. In actual practice, insulating oil can also be used as the cooling medium. Compared with water, the cost is slightly higher, but it has better insulation performance. For example, the use of common transformer insulating oil is also feasible.

[0029] like Figure 11 As shown, a connecting groove 23 is provided between the water storage tank 21 and the battery box body 1. The connecting groove 23 is used for the heat conducting plate to pass through. A sealing mechanism is installed on the outside of the connecting groove 23. The sealing mechanism is used to prevent water leakage. The sealing mechanism includes a mounting block 24 and an elastic diaphragm 25. The elastic diaphragm 25 is fixedly connected to the outside of the mounting block 24 to achieve dynamic sealing. The mounting block 24 is fixedly connected to the outside of the connecting groove 23 by bolts, and the elastic diaphragm 25 blocks the connecting groove 23 to ensure sealing.

[0030] like Figure 12 As shown, the external limit plug of the mounting plate 26 is connected with multiple groups of heat conducting plates 27 arranged at equal intervals. The heat conducting plates 27 are used for heat conduction, and the bottom of the heat conducting plates 27 is slidably connected to the inner side of the connecting groove 23 to achieve up and down movement. A tension spring 28 is fixedly connected between the mounting plate 26 and the bottom of the battery box body 1. The tension spring 28 provides a reset force. A fixed plate 29 is fixedly connected to the inner side of the battery box body 1. The fixed plate 29 serves as a guide support. A connecting rod 31 is fixedly connected to the upper side of the mounting plate 26, and the connecting rod 31 and the fixed plate 29 are slidably connected to achieve guided movement. A slide groove 30 is provided on the outside of the fixed plate 29, and the connecting rod 31 is slidably connected to the inner side of the slide groove 30 to ensure movement accuracy.

[0031] like Figure 12 As shown, a positioning hole 32 is provided on the outside of the connecting rod 31, and the positioning hole 32 is used for locking. A fixing seat 33 is fixedly connected to the upper side of the fixing plate 29, and the fixing seat 33 serves as the base of the locking mechanism. A wedge block 34 is slidably connected to the inner side of the fixing seat 33, and the wedge block 34 is used for locking. A slope is provided on the bottom of the wedge block 34, and the slope matches the connecting rod 31 to achieve automatic guiding, and the wedge block 34 matches the positioning hole 32 to ensure reliable locking. A compression spring 35 is fixedly connected to the inner side of the fixing seat 33, and the compression spring 35 is fixedly connected to one side of the wedge block 34 to provide a reset elastic force. The compression spring 35 is sleeved on the outside of the traction rope 36 to keep the structure compact. The outside of the rotating shaft 12 is fixedly connected to the traction rope 36, and the end of the traction rope 36 passes through the outside of the fixing seat 33 and is fixedly connected to one side of the wedge block 34 to achieve remote control.

[0032] like Figure 13 As shown, a groove is provided at the inner bottom of the battery box body 1, and the groove is located below the two ends of the mounting plate 26, serving as the installation space for the lifting mechanism. A mounting seat 37 is fixedly connected in the groove, and the mounting seat 37 serves as a supporting base. An electric push rod 38 is detachably connected to the inner side of the mounting seat 37, and the electric push rod 38 provides lifting power. A top plate 39 is fixedly connected to the upper side of the electric push rod 38, and the top plate 39 is used to lift the mounting plate.

[0033] like Figure 2A PLC processor 40 is fixedly connected to the outside of the battery box body 1. The PLC processor 40 serves as the control center, and the PLC processor 40 is electrically connected to the battery body 4, drive motor 10, fan 15, liquid level sensor 20, refrigerator 22 and electric push rod 38 to achieve intelligent control.

[0034] In this embodiment, when the heat dissipation net 5 is closed due to waterproof requirements, in order to maintain the heat dissipation efficiency required for continuous operation of the battery, the system automatically switches to the water cooling mode. When the driving motor 10 drives the rotating shaft 12 to rotate, the fixed cylinder 14 is synchronously driven to rotate 180 degrees, so that the air outlet direction of the fan 15 is changed from upward diversion to downward blowing, forcing the heat of the battery to be directed to the bottom. At the same time, the traction rope 36 is wound during the rotation of the rotating shaft 12, and the wedge block 34 in the traction fixing seat 33 overcomes the resistance of the compression spring 35 and disengages from the positioning hole 32 of the connecting rod 31. The connecting rod 31 then moves downward along the slide groove 30 under the action of the deadweight of the mounting plate 26 and the tension of the tension spring 28, pushing the heat conducting plate 27 through the connecting groove 23. Inserted into the water inside the water tank 21, the elastic diaphragm 25 ensures that there is no leakage at the connection between the heat conducting plate 27 and the water tank under the sealing action of the mounting block 24, so that the end of the heat conducting plate 27 is in full contact with the cold water. At this time, the refrigerator 22 is started, and its cold end quickly cools the water in the water tank 21. After the battery heat is forcibly guided to the heat conducting plate 27 by the fan 15, the heat conducting plate 27 is efficiently transferred to the end immersed in cold water, and rapid heat exchange is achieved through water-cooled contact. This design not only closes the heat dissipation net 5 to block rainwater, but also simultaneously activates efficient water cooling. Only a single motor drive is required to complete the seamless switching of air cooling / water cooling mode, avoiding the risk of battery short circuit caused by high temperature, and the operation process is automated, convenient and reliable.

[0035] When the rain stops or the risk of water seepage is eliminated and the initial heat dissipation state needs to be restored, the drive motor 10 can be controlled to reverse, on the one hand, driving the slide plate 7 to reset, so that the heat dissipation holes 8 are aligned with the heat dissipation net 5 again, and at the same time, the rotating shaft 12 drives the fan 15 to flip so that the air outlet direction is readjusted to blow air upward, ready to dissipate heat through the heat dissipation net 5. At the same time, the reversal of the rotating shaft 12 releases the winding tension of the traction rope 36, and pushes the wedge block 34 to reset toward the connecting rod 31 through the compression spring 35. Then, by starting the electric push rod 38, the top plate 39 connected thereto is pushed upward. The top plate 39 acts on the two ends of the mounting plate 26 to push it upward together with the connecting rod 31, and the connecting rod 31 slides upward along the slide groove 30 of the fixing plate 29. When the connecting rod 31 rises to its When the end contacts the inclined surface at the bottom of the wedge block 34, under the guidance of the inclined surface, the connecting rod 31 continues to rise, forcing the wedge block 34 to retract toward the inside of the fixing seat 33, and the connecting rod 31 continues to rise until the positioning hole 32 thereon rises to a position aligned with the wedge block 34. At this time, the wedge block 34 is quickly ejected under the strong elastic force of the compression spring 35 and reinserted into the positioning hole 32 of the connecting rod 31, firmly locking the connecting rod 31 and the mounting plate 26 in the initial high position. The heat conducting plate 27 is then completely pulled out of the cooling water in the water tank 21 and disengaged. The overall structure can be restored to the initial upper exhaust and heat dissipation state, and the reset process is also mainly completed by the coordinated action of the reversal of the drive motor 10 and the electric push rod 38, which is convenient and efficient.

[0036] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
