Process of taking battery from the powered device 100:

when the electric device 100 detects that the battery 300 is short of power, the electric device 100 automatically operates to a designated charging position. The two yoke arms 200 are protruded above the second stopping assembly 120, and then the two yoke arms 200 are moved downward in the second direction to press down against the blocking plate 122 of the second stopping assembly 120 and compress the first elastic member 123. The fork arm 200 continuously extends forwards to the bottom of the battery 300 along the first direction, when the fork arm 200 extends forwards for a preset distance, the limiting flange 210 penetrates into the limiting groove 320, then the fork arm 200 directly retreats to take out the battery 300 or the fork arm 200 lifts the battery 300 upwards to take out the battery 300, and then the battery 300 with low electric quantity is sent to a designated charging position for charging.

Process of providing battery to the electric device 100:

after the low-battery cell 300 is taken out, the fork 200 takes out a fully charged cell 300 in the cell exchange system, then as shown in fig. 9, the fork 200 drives the cell 300 to move to above the second position-limiting component 120, then the two fork 200 move downward along the second direction to press the blocking plate 122 of the second position-limiting component 120 downward and compress the first elastic member 123, and then the fork 200 continues to extend forward along the first direction until the cell 300 abuts against the abutting member 112. In the process that the fork arm 200 drives the battery 300 to extend into the first direction or when the battery 300 is fully charged, the limiting flange 210 penetrates into the limiting groove 320. After the battery 300 abuts against the abutting part 112, the fork arm 200 continues to drive the battery 300 to move forward and compress the second elastic part 113, when the front section 220 of the fork arm 200 passes through the upper part of the blocking plate 122, as shown in fig. 10, the first elastic part 123 ejects the blocking plate 122 out between the rear sections 230 of the two fork arms 200, so that the second limiting component 120, the first limiting component 110 and the third limiting component 140 limit the battery 300, the first limiting component 110 tightly abuts against the battery 300, the battery electrode 310 is in contact with the power utilization electrode 130 of the power utilization device 100, the fork arm 200 moves downwards for a certain distance until the limiting flange 210 and the limiting groove 320 are separated, the fork arm 200 is pulled out from the lower part of the blocking plate 122, and the placement of the battery 300 is completed.

The technical principle of the present invention is described above in connection with specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention.
