[0034] Further, power supply 2 is equipped with charging head 21, power supply 2 outer wall is equipped with shell 22, shell 22 is set with sliding slot 23, sliding slot 23 is connected with dust cover 24 slidingly, dust cover 24 is hinged with hinge rod 25, the end away from dust cover 24 of hinge rod 25 is hinged with sliding block 26, sliding block 26 is penetrated by rod body 27 and is connected with rod body 27 slidingly, rod body 27 penetrates placing plate 44 and is connected with placing plate 44 slidingly, both ends of rod body 27 are fixedly connected with the inner wall of base 1, sliding block 26 is elastically connected with the inner wall of base 1 by spring, hinge rod 25 and sliding block 26 are equipped with two groups, two groups of sliding blocks 26 are symmetrically distributed on the both sides of power supply 2;

[0035] In this utility model, during use, the battery pack body 3 is first placed on the outer wall of the placement plate 44, and then the motor 41 is started. When the motor 41 starts, as... Figure 6 As shown, the limiting rod 422 is located at the bottom of the second toothed sleeve 42 and is used to limit the second toothed sleeve 42. Therefore, when the motor 41 drives the first toothed sleeve 411 to rotate, the inclined surface of the first toothed sleeve 411 will apply a force to the inclined surface of the second toothed sleeve 42, causing the first toothed sleeve 411 to drive the second toothed sleeve 42 to rotate synchronously. Therefore, when the second toothed sleeve 42 rotates, the screw 43 that is slidably connected to it will rotate synchronously, causing the placement plate 44 to drive the battery pack body 3 to move towards the power source 2. When the placement plate 44 moves a certain distance, the placement plate 44 will press the slider 26, causing the slider 26 to move. At the same time, the spring connected to the slider 26 will undergo elastic deformation. When the slider 26 moves, the hinge rod 25 will apply a force to the dust cover 24, causing the dust cover 24 to move upward, thereby exposing the charging head 21. Subsequently, the battery pack body 3 will be driven by the motor 41 to make the charging head 21 connect with the socket 31, thereby completing the charging operation of the battery pack body 3.

[0036] When the charging head 21 is inserted into the socket 31, the placement plate 44 presses against the sliding plate 431, causing the sliding plate 431 to move. As the sliding plate 431 moves, the pull rod 432 moves. During this process, the inclined groove 433 presses against the limiting rod 422, causing the limiting rod 422 to move and thus releasing the limiting position of the toothed sleeve 42. Subsequently, when the inclined surface of the toothed sleeve 411 applies force to the inclined surface of the toothed sleeve 42, the toothed sleeve 42 slides under pressure. Simultaneously, under the action of the spring, the toothed sleeve 411 and the toothed sleeve 42 continuously overlap and disengage, allowing the toothed sleeve 411 to spin freely. This prevents the placement plate 44 from excessively pressing the battery pack body 3 against the charging head 21, thus preventing damage. When the battery pack body 3 is fully charged... At this time, the drive motor 41 rotates in the reverse direction. The straight edge of the first gear sleeve 411 will apply a force to the straight edge of the second gear sleeve 42, causing the screw 43 to drive the placement plate 44 to disengage the battery pack body 3 from the power supply 2. When the placement plate 44 disengages from the sliding plate 431, the sliding plate 431 will drive the pull rod 432 back to its original position under the action of the spring. During this process, the inclined groove 433 will apply a force to the limiting rod 422 again, causing the limiting rod 422 to limit the second gear sleeve 42 again. When the placement plate 44 disengages from the slider 26 under the drive of the motor 41, the slider 26 will return to its original position under the action of the spring. At the same time, through the transmission of the hinge rod 25, the dust cover 24 returns to its original position, thereby protecting the charging head 21 again and preventing dust in the air from adhering to the outer wall of the charging head 21 when it is idle.

[0037] The above merely describes preferred embodiments of the present application, and does not limit the patent scope of the present application, and any equivalent structural transformation or direct / indirect application in other related technical fields under the inventive concept of the present application, and by using the content of the present application specification and drawings, are included in the patent protection scope of the present application.
