Example

[0024] refer to Figure 8 and Fig. 9 As shown, the locking mechanism 7 includes: A through hole 701 formed on the side wall of the lock box 6; A driving block 702 movably disposed inside the lock box 6, the driving block 702 is arranged in an elliptical cam shape, and an unlocking groove 703 is provided on the side wall of the driving block 702, and the unlocking groove 703 is adapted to the unlocking cam 204; Two connecting seats 704 are respectively fixedly connected to the two side walls of the lock box 6, and a pull rod 705 is movably provided in the middle of the two connecting seats 704; A push piece 706 fixedly connected to the side wall of the pull rod 705, and two push pieces 706 are respectively located on both sides of the driving block 702; Two pressure plates 708 are fixedly connected to the side wall of the pull rod 705, and a first spring 707 is arranged between the pressure plate 708 and the connecting seat 704; A lock plate 709 fixedly connected to one end of the pull rod 705, two lock rods 710 fixedly connected to the side wall of the lock plate 709, and the lock rods 710 are movably connected to the lock box 6; and The locking holes 711 are respectively formed on the inner wall of the battery compartment 4 and the charging base 208 , and the locking rod 710 is matched with the locking holes 711 .

[0025] By setting the through opening 701, the driving block 702, the unlocking groove 703, the connecting seat 704, the pull rod 705, the pushing piece 706, the pressure plate 708, the first spring 707, the locking plate 709, the locking rod 710 and the locking hole 711, the lock box 6 is locked and limited with the battery compartment 4 and the charging seat 208 through the adaptation of the locking rod 710 and the locking hole 711, and the driving block 702 is rotated to push the pushing piece 706, and the pushing piece 706 drives the pull rod 705 to move. In this process, the pull rod 705 drives the locking plate 709 to move so that the locking rod 710 is separated from the locking hole 711, thereby realizing the unlocking operation of the lock box 6 with the battery compartment 4 and the charging seat 208. The unlocking cam 204 is adapted to the unlocking groove 703 so that the unlocking cam 204 can drive the rotation of the driving block 702, thereby realizing the locking and unlocking of the unlocking box 6. The implementation method is as follows: Battery block 5 locking: When the battery block 5 is placed in the lock box 6 or the battery compartment 4, the lock rod 710 at one end of the lock plate 709 will automatically align with the lock hole 711 on the side wall of the lock box 6 or the battery compartment 4. Since the first spring 707 is provided between the two pressure plates 708 on the side wall of the pull rod 705 and the connecting seat 704, the first spring 707 is in a supporting state to provide a supporting force for the pull rod 705. Under the action of the first spring 707, the lock rod 710 will be firmly supported into the lock hole 711 to achieve battery locking; Unlocking the battery block 5: First, the positioning plate 205 is unlocked from the lock box 6, and the positioning hole 206 and the positioning block 207 are adapted to realize a limited connection between the positioning plate 205 and the lock box 6. The through-hole 701 on the side wall of the lock box 6 allows the unlocking cam 204 to enter the interior of the lock box 6 and contact the unlocking groove 703 on the side wall of the driving block 702. When the battery needs to be unlocked, the driving motor 203 is started to drive the unlocking cam 204 to rotate. The rotation of the unlocking cam 204 will push the driving block 702 (elliptical cam shape) to rotate in the lock box 6. The rotation of the driving block 702 will squeeze the movement of the push sheet 706, so that the push sheet 706 drives the pull rod 705 to move. In this process, the movement of the pull rod 705 causes the pressure plate 708 to squeeze the first spring 707 to contract, so that the lock plate 709 follows the movement of the pull rod 705. In this process, the lock rod 710 disengages from the lock hole 711.

[0047] In this embodiment, the heat dissipation and protection of the power exchange box 1 are achieved through the cooperation of the heat dissipation port 21 and the protection frame 22.

[0048] It should be noted that the present invention is an automatic battery replacement device for unmanned aerial vehicles. When in use, when the unmanned aerial vehicle body 3 is parked on the box cover 8, the T-shaped foot 901 enters the interior of the positioning tube 902, and the positioning bar 905 moves and contacts with the T-shaped foot 901 to limit the T-shaped foot 901, so that the unmanned aerial vehicle body 3 can achieve stable battery replacement operation. The two first electric push rods 201 respectively drive the positioning plate 205 to contact the lock box 6 inside the battery compartment 4 and the lock box 6 inside the charging seat 208. The positioning hole 206 is adapted to the positioning block 207, so that the positioning plate 205 and the lock box 6 are limitedly connected. The through-hole 701 on the side wall of the lock box 6 allows the unlocking cam 204 to enter the lock box 6 and contact the unlocking groove 703 on the side wall of the driving block 702. When it is necessary to unlock the battery, the driving motor 203 is started to drive the unlocking cam 204 to rotate, and the rotation of the unlocking cam 204 will push the driving block 702 (elliptical cam setting) When rotating in the lock box 6, the rotation of the drive block 702 will squeeze the movement of the push piece 706, so that the push piece 706 drives the pull rod 705 to move. In this process, the movement of the pull rod 705 causes the pressure plate 708 to squeeze the first spring 707 to contract, so that the lock plate 709 moves with the pull rod 705. In this process, the lock rod 710 disengages from the lock hole 711, and then the two groups of first electric push rods 201 pull the battery block 5 into the battery exchange box 1, and the third electric push rod 113 pushes or pulls the movable plate 10 to move, so that the spare battery block 5 is located below the drone body 3, and the used battery block 5 is located below another group of charging seats 208. By starting the transportation of the first electric push rod 201, the battery block 5 is respectively transported to the battery compartment 4 and the charging seat 208, and then the reverse driving of the drive motor 203 is realized to realize the unlocking operation of the lock box 6, so that the lock box 6 is limitedly connected with the battery compartment 4 and the charging seat 208, and the battery removal and replacement operation of the battery block 5 is completed.
