The outer periphery of the connecting shaft 26 is fixedly connected to the bevel gear 2 34. The bevel gear 1 28 is meshed with the bevel gear 2 34, and the meshing of the bevel gear 1 28 and the bevel gear 2 34 allows the bevel gear 1 28 to drive the bevel gear 2 34 to rotate.

[0046] Reference Figure 4-Figure 6 The other end of the telescopic shaft 16 is fixedly connected to a limit plate 25, and the limit plate 25 is slidably connected to the inside of the installation shaft 14. The installation of the limit plate 25 can limit the movement of the telescopic shaft 16. A spring 23 is abutted on one side of the limit plate 25, and one end of the spring 23 abuts on the inside of the installation shaft 14. The spring 23 can push the telescopic shaft 16 to move. The front and rear sides of the bearing plate 2 are fixedly connected to limit blocks 22, and the limit blocks 22 are slidably connected to the inside of the connecting block 20.

Two grooves are provided inside the fixed shaft 15, and the protrusions 24 are slidably connected inside the grooves. The grooves are used to receive the protrusions 24.

[0047] Working principle: before using the device, multiple battery modules are placed on the top sides of multiple carrier plates 2, and then the battery modules are pressed to move the carrier plates 2 downward. During the movement of the carrier plates 2, the two limit blocks 22 drive the two connection blocks 20 to move respectively, and the two connection blocks 20 drive the two clamping plates 12 to move towards each other and clamp the battery modules to fix the battery modules on the top side of the carrier plates 2. During the movement of the carrier plates 2, the two protrusions 24 are driven to move, and the protrusions 24 move along the fixed shaft 15 and are inserted into the grooves inside the fixed shaft 15 to fix the position of the carrier plates 2 so that the clamping plates 12 maintain the clamping state of the battery modules, thereby completing the installation of multiple battery modules. When the battery module needs to be replaced, the battery module is pressed downward to drive the protrusion 24 to contact the block 21 outside the fixed shaft 15. During the downward movement of the supporting plate 2, the rubber pad 6 is elastic and can shrink, so that the supporting plate 2 can move downward, and then the protrusion 24 moves along the block 21 and moves to the bottom of the block 21, and then the battery module is pulled upward. The protrusion 24 is pushed by the telescopic shaft 16 to be close to the block 21 and drive the block 21 to move upward. When the block 21 contacts another block 21, the protrusion 24 moves upward along the two blocks 21 to enable the supporting plate 2 to continue to move upward. The upward movement of the supporting plate 2 causes the two clamps 12 to no longer clamp the battery module, and then the battery module can be taken out from the box body 4 for replacement. When the battery module box is used, the two driving motors inside the two mounting blocks 29 can be started to drive the two fans 31 to rotate. The rotation of the two fans 31 drives air flow into the box body 4 to cool the battery modules inside the box body 4. The two motors 32 are started while the fans 31 rotate. The driving end of the motor 32 drives the bevel gear 1 28 to rotate. The rotation of the bevel gear 1 28 drives the bevel gear 2 34 to rotate. During the rotation of the bevel gear 2 34, the mounting frame 2 35 is driven to rotate through the connecting shaft 26. The rotation of the mounting frame 2 35 drives the mounting block 29 to rotate, thereby adjusting the angle of the fan 31, thereby increasing the flow range of the airflow and improving the cooling efficiency of the airflow.
