Description

Technical Field

[0001] The utility model belongs to the technical field of energy storage end plates, and in particular relates to a combined energy storage end plate. Background Art

[0002] The promotion and use of new energy vehicles is becoming increasingly widespread, and new energy vehicles mostly use pure electric energy or hybrid energy of batteries and gasoline. The energy storage end plate refers to the plate installed above the positive and negative poles of the battery in the new energy vehicle, also called the end cover or pole cover, which is used to fix the positive and negative poles of the battery and seal and protect the internal structure of the battery.

[0003] Existing energy storage end plates for new energy vehicle batteries electrically connect the positive and negative electrodes of the battery to the electrical connectors of the energy storage end plates, and set the energy storage end plates above the batteries, and set a corresponding number of energy storage end plates according to the number of batteries, so as to better seal and protect the batteries. However, when setting a corresponding number of energy storage end plates, two groups of adjacent end plates are riveted together by rivets to ensure the connection stability between the end plates. However, since the battery is the core component of the electric vehicle, the energy storage battery needs to be inspected and maintained regularly. Therefore, it is troublesome to disassemble the riveted energy storage end plates in the later stage to check the internal condition of the battery, and the energy storage end plates need to be re-riveted after disassembly, which greatly reduces the maintenance time. Utility Model Content

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] (1) By setting two groups of end plates horizontally and rotating the turntable on the surface of one group of end plates in opposite directions, the turntable drives the positive and negative screws to rotate. The positive and negative screws rotate and drive the sleeves with threads connected at both ends to move toward the end away from the turntable, thereby driving the clamping rod on the surface of the sleeve to move into the opening on the surface of the vertical plate, so that the fixing plate of the other group of end plates can be inserted into the end plate fixing groove behind the adjustment clamping rod, and the turntable is rotated forward. The turntable drives the positive and negative screws to rotate forward, thereby causing the sleeve to move toward the end close to the turntable, and driving the clamping rod to move out of the opening on the surface of the vertical plate and engage with the clamping grooves on both sides of the fixing plate, so that the fixing plate is clamped and fixed into the fixing groove, thereby the two groups of end plates are clamped and fixed, and installation and fixing are relatively convenient. When disassembling, it is only necessary to rotate the turntable to drive the clamping rod to disengage from the clamping connection with the fixing plate, thereby greatly improving the maintenance efficiency.

[0018] (2) Cooling water is injected into one end of the water inlet, and the cooling water enters the serpentine cooling tube for circulation, thereby absorbing the heat generated by the battery pack on the end plate surface during operation while circulating, and further transmitting the heat to the water outlet, and the cooling water after absorbing the heat is discharged from the water outlet, thereby completing the heat exchange. The battery can be protected by the end plate and cooled at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the positive and negative threaded rods 6 rotate, they can drive the sleeves 12 at both ends to approach or move away from each other.

[0029] The anti-loosening component is arranged on the surface of the end plate 1, and the latch 17 of the anti-loosening component is plugged into the latch hole on the surface of the connecting component 5, so that the latch 17 limits the connecting component 5 to prevent the connecting component 5 from rotating by itself.

[0030] The turntable 9 is fixedly sleeved in the middle of the positive and negative threaded rod 6 and the pin hole is arranged on the surface of the turntable 9. Both ends of the positive and negative threaded rod 6 are threadedly connected with a sleeve 12. The bottom of the sleeve 12 is slidably connected with the slide groove 20 provided in the end plate 1 through a slider 19. When the sleeve 12 moves, the bottom slides through the slider 19 and the slide groove 20, thereby enhancing the stability of the sleeve 12 when it moves.

After the fixing plate 4 is inserted into the fixing slot 14, the fixing plate 4 is fixed by connecting the card rod 7 with the card slot 13. The turntable 9 on the surface of a group of end plates 1 is rotated in the opposite direction, so that the turntable 9 drives the positive and negative screw rods 6 to rotate. When the positive and negative screw rods 6 rotate, the sleeve 12 with threads connected at both ends is driven to move toward the end away from the turntable 9, thereby driving the card rod 7 on the surface of the sleeve 12 to move into the opening on the surface of the vertical plate 8. When the card rod 7 moves into the opening, the fixing plate 4 can be inserted into the fixing slot 14 without the obstruction of the card rod 7 in the fixing slot 14.

[0031] A serpentine cooling pipe 15 is provided in the end plate 1, and the two ends of the serpentine cooling pipe 15 are respectively connected to the water inlet 2 and the water outlet 3. Cooling water is injected into the water inlet 2, and the cooling water circulates in the serpentine cooling pipe 15 and then flows out from the water outlet 3, thereby completing heat exchange.

[0032] A plurality of mounting blocks 16 for fixing to the end plate 1 are disposed on the surface of the serpentine cooling tube 15 .

[0033] The anti-loosening component includes an elastic rope 18, one end of which is connected to the handle on the surface of the end plate 1, and the other end is connected to the pin 17. The pin 17 is plugged into the pin hole on the surface of the turntable 9, so that the turntable 9 can be restricted to avoid the problem that after the engaging rod 7 is engaged with the fixing plate 4, the turntable 9 is accidentally rotated, causing the engaging rod 7 to be disengaged from the fixing plate 4.

[0034] The combined energy storage end plate is arranged horizontally with two groups of end plates 1, and the turntable 9 on the surface of one group of end plates 1 is rotated in the opposite direction, so that the turntable 9 drives the positive and negative screw rods 6 to rotate. The positive and negative screw rods 6 rotate and drive the sleeves 12 threaded at both ends to move toward the end away from the turntable 9, thereby driving the clamping rod 7 on the surface of the sleeve 12 to move into the opening on the surface of the vertical plate 8, so that the fixing plate 4 of the other group of end plates 1 can be inserted into the fixing groove 14 of the end plate 1 behind the adjustment clamping rod 7, and the turntable 9 is rotated forwardly, and the turntable 9 drives the positive and negative screw rods 6 to rotate forwardly, so that the sleeve 12 moves toward the end close to the turntable 9, and drives the clamping rod 7 to move out of the opening on the surface of the vertical plate 8 and engage with the clamping grooves 13 on both sides of the fixing plate 4, so that the fixing plate 4 is clamped and fixed into the fixing grooves 14, so that the two groups of end plates 1 are clamped and fixed, and the installation and fixing are relatively convenient. When disassembling, it is only necessary to rotate the turntable 9 to drive the clamping rod 7 to disengage from the clamping connection with the fixing plate 4, thereby greatly improving the maintenance efficiency.

[0035] By injecting cooling water into one end of the water inlet 2, the cooling water enters the serpentine cooling tube 15 for circulation, thereby absorbing the heat generated by the battery pack on the surface of the end plate 1 when it is working, and further transmitting it to the water outlet 3, and the cooling water after absorbing the heat is discharged from the water outlet 3, thereby completing the heat exchange. The battery can be protected by the end plate 1 while also being cooled.
