[0031] See also Figure 1-Figure 6 A battery box structure includes a box body 1 and a box cover 2. The box cover 2 is detachably mounted at the top opening of the box body 1. A grip mechanism 4 is rotatably mounted on the top of the box cover 2. One end of the grip mechanism 4 extends into the box body 1 and is opposite to the battery cell module 7 in the box body 1. By rotating the grip mechanism 4, the end of the grip mechanism 4 located inside the box body 1 grabs the battery cell module 7, so as to extract and lift the battery cell module 7, thereby effectively improving the assembly, repair and disassembly efficiency of the battery pack;

[0032] Specifically, Figure 2 and Figure 4 As shown, a cross bar 8 corresponding to and adapted to the handle mechanism 4 is installed on the top of the battery module 7, and one end of the handle mechanism 4 located inside the box body 1 is detachably connected to the cross bar 8;

With such a design, the card slot can perform a circular motion with the rotating frame 42 as the center, so that the hook 43 is clamped with the cross bar 8;

[0036] Furthermore, a magnet located outside the slot is installed on the hook 43, and the cross bar 8 is made of iron. When the hook 43 is connected with the cross bar 8, the tightness of the connection between the hook 43 and the cross bar 8 can be improved by magnetic attraction.

[0037] Furthermore, a positioning member arranged opposite to the hook 43 is installed on the top wall of the box cover 2, and the hook 43 can be connected to the positioning member, so as to limit the position of the hook 43, which can prevent the handle mechanism 4 from shaking during transportation;

[0038] The positioning member can be an iron product or a slot structure in the prior art, or the hook 43 can be magnetically positioned by using the principle of magnets with opposite poles attracting each other;

[0039] Specifically, Figure 3 As shown, a positioning track 9 is installed on the outer wall of the battery module 7, and a positioning bar 10 corresponding to and adapted to the positioning track 9 is installed on the inner wall of the box body 1, and the battery module 7 is lifted and slid along the positioning bar 10 in a vertical plane through the positioning track 9;

By sliding and plugging the positioning rail 9 and the positioning bar 10, the packing stability and installation stability of the battery module 7 can be improved;

[0041] Furthermore, there are multiple positioning rails 9 and they are evenly distributed on the outer side of the battery module 7 in the circumferential direction;

[0043] Furthermore, the lower surface of the positioning ring 11 has a rubber pad, which is arranged between the box bottom 3 and the positioning ring 11, and can improve the tightness of the connection between the two and play a role in sealing the bottom opening of the box body 1;

[0044] Furthermore, the positioning ring 11 is a rectangular ring, and the inner wall of the positioning ring 11 and the box bottom 3 are both installed with connecting blocks, the connecting block of the positioning ring 11 is provided with 12, and the connecting block of the box bottom 3 is provided with a threaded hole, and the two connecting blocks are connected by screws to achieve the clamping connection between the positioning ring 11 and the box bottom 3, and the design of the rubber pad is combined to improve the sealing performance;

[0045] Furthermore, a protrusion 13 is installed on the inner wall of the positioning ring 11, and a groove 14 is installed on the inner wall of the box bottom 3. The protrusion 13 is engaged with the groove 14, which facilitates the assembly of the box bottom 3 and the groove 14.

[0046] Furthermore, the box bottom 3 is disc-shaped and matches the bottom end of the box body 1. A positioning plate is installed at the bottom of the inner cavity of the box bottom 3.

When the battery module 7 is installed into the box, the positioning column is plugged into the positioning hole 15 for positioning, thereby improving the installation stability of the battery module 7 in the box body 1.

[0047] In this embodiment, if Figure 1As shown, the box cover 2 is equipped with an air pressure sensor 5 and an exhaust valve 6. The air pressure in the box body 1 is detected by the air pressure sensor 5 and an inflation alarm is issued, and the inflation is automatically exhausted by the exhaust valve 6;

[0048] Specifically, an indicator light is installed on the air pressure sensor 5. When the air pressure is normal, the indicator light shows green, and when the air pressure exceeds the standard, the indicator light shows red, thereby alerting the user;

[0049] Specifically, Figure 6 As shown, the exhaust valve 6 includes an exhaust cylinder 61 and an exhaust pipe 63. The exhaust cylinder 61 is installed on the box cover 2, and the upper and lower ends of the exhaust cylinder 61 extend to the upper and lower sides of the box cover 2 respectively. The exhaust pipe 63 is slidably sleeved in the exhaust cylinder 61, and the exhaust pipe 63 can rise and fall with the rise and fall of the air pressure in the box body 1. The upper end outer wall of the exhaust cylinder 61 has a first exhaust hole, and the upper end outer wall of the exhaust pipe 63 has a second exhaust hole. As the air pressure in the box body 1 gradually increases, the exhaust pipe 63 gradually moves up to drive the second exhaust hole to be connected with the first exhaust hole, thereby realizing automatic exhaust.

[0050] Furthermore, the exhaust valve 6 also includes a bolt 62, a pressure plate 64 and an elastic member 65. The bolt 62 is threadedly sleeved on the upper opening of the exhaust pipe 61 for sealing. The lower end of the exhaust pipe 63 extends to the bottom of the exhaust pipe 61 and is connected to the pressure plate 64. The upper end of the exhaust pipe 63 is connected to the bottom end of the bolt 62 through the elastic member 65.

[0051] When the air pressure in the box body 1 gradually increases, the pressure plate 64 gradually moves upward under the action of the air pressure, and the exhaust pipe 63 gradually moves upward in the exhaust tube 61 and squeezes the elastic member 65, and the elastic member 65 is in a compressed state. When the air pressure in the box body 1 exceeds the standard, the exhaust pipe 63 moves to the highest point in the box body 1, and the second exhaust hole is connected with the first exhaust hole. The gas in the box body 1 is discharged outward through the exhaust valve 6, and the automatic exhaust after the flatulence is realized. As the other gas in the box body 1 is gradually discharged, the air pressure in the box body 1 gradually decreases, the pressure on the pressure plate 64 becomes smaller, and the elastic member 65 gradually returns to its original state. The exhaust pipe 63 drives the pressure plate 64 to move downward, and the second exhaust hole is not connected with the first exhaust hole, so that sealing can be achieved;

[0052] In summary, the battery box structure proposed by the utility model drives the rotating frame 42 to rotate through the handle 41, so that the hook 43 rotates, and the slot at the bottom end of the hook 43 is engaged with the outer periphery of the cross bar 8, so that the battery module 7 can be lifted up by the grip mechanism 4, thereby facilitating the battery module 7 to be loaded into the box body 1, and then the positioning rail 9 installed on the outer wall of the battery module 7 is inserted and slid along the positioning bar 10 on the inner wall of the box body 1 to realize the positioning and installation of the battery module 7, effectively stabilize the battery module 7, and then the bottom of the battery module 7 is engaged with the box bottom 3, further The installation stability of the battery module 7 is further improved, and the battery module 7 is prevented from being offset after being packed and causing collision and leakage, thereby reducing safety hazards and improving safety in use; by installing a box cover 2 at the top opening of the box body 1, the air pressure in the box body 1 can be monitored in real time by using the air pressure sensor 5 installed on the box cover 2 to send a flatulence alarm. When the air pressure in the box body 1 reaches a set value, the exhaust valve 6 installed on the box cover 2 is used to automatically exhaust the excessive air pressure in the box body 1, thereby achieving effective control of the air pressure in the box body 1, which is conducive to eliminating the safety hazards caused by flatulence.
