[0026] like Figures 4 to 6As shown, the male head 2 includes a male head base 201 and a male head body 202 fixed on the male head base 201, a second opening 203 is provided on the male head body 202, a mobile base 204, a second connection mechanism 205 fixed on the mobile base 204, a slide bar 206 and a driving rod 207 provided at both ends of the mobile base 204 are provided in the second opening 203, the driving rod 207 is connected to a reduction motor 208, a first communication module 209 is provided in the reduction motor 208, the reduction motor 208 is used to drive the driving rod 207, the driving rod 207 is used to drive the mobile base 204 and the second connection mechanism 205 to move on the slide bar 206 and the driving rod 207, and at least one second through hole 210 is provided on the side of the second connection mechanism 205.

[0027] like Figure 7 As shown, a control mechanism 3 is provided inside the female body 102, and the control mechanism 3 includes a single-chip microcomputer 301, an electromagnetic coil driver 302 for driving the electromagnetic coil 109, a reduction motor driver 303 for driving the reduction motor 208, and a second communication module 304 for communicating with the first communication module 209, and the proximity switch 105, the second communication module 304, the electromagnetic coil driver 302 and the reduction motor driver 303 are all connected to the single-chip microcomputer 301.

[0028] According to the present invention, when the male head 2 of the automatic connection device is relatively close to the female head 1, the proximity switch 105 on the female head 1 senses the connection of the male head 2, and the signal feedback transmits the information to the single-chip microcomputer 301. The single-chip microcomputer 301 outputs a control signal to the electromagnetic coil driver 302 through the signal feedback, so that the electromagnetic coil 109 generates an electromagnetic force to eject the ejection rod 111 (preferably, the ejection rod is a galvanized iron rod) and adsorb to the second magnet 110, so as to prevent the ejection rod 111 from hindering the connection between the female head 1 and the male head 2. Then, the single-chip microcomputer 301 outputs a command to the reduction motor driver 303, and the reduction motor driver 303 sends a drive signal to the first communication module (preferably, the first communication module and the second communication module are both wireless communication modules) through the second communication module to start the reduction motor 208.

When the male head 2 extends the second connection structure 205 completely into the female head 1, the single chip computer 301 outputs a control signal to the electromagnetic coil driver 302, so that the electromagnetic coil 109 generates an electromagnetic force to eject the ejection rod 111 and adsorb it to the first magnet 107. At this time, the ejection rod is respectively stuck in the channel 108, the first through hole 106 and the second through hole 210, and the male head 2 and the female head 1 are safely and automatically connected together. Therefore, the present invention only needs to install the female head on the cleaning robot and the male head on the drone, so as to provide an automatic connection device for the drone to deliver the cleaning robot without manual labor.

The present invention electrically connects the reduction motor driver 303 with the reduction motor 208 through the third magnet 4 and the fourth magnet 5, thereby realizing direct transmission of the drive signal, avoiding the problem of inability to connect when the first communication module and the second communication module cannot communicate normally.

[0031] Furthermore, four third magnets 4 are symmetrically arranged on the top of the female body 102, and the four third magnets 4 are connected in parallel with each other. Four fourth magnets 5 are symmetrically arranged on the top of the male body 202, and the four fourth magnets 5 are connected in parallel with each other. In order to avoid poor contact of a third magnet or a fourth magnet, the present invention provides four third magnets 4 symmetrically arranged on the top of the female body 102, and the four third magnets 4 are connected in parallel with each other. Four fourth magnets 5 are symmetrically arranged on the top of the male body 202, and the four fourth magnets 5 are connected in parallel with each other, so as to prevent a poor connection between one pair and cause a circuit blockage.

[0032] Preferably, the side of the first connection mechanism 104 is symmetrically provided with four first through holes 106, the interior of the first connection mechanism 104 is symmetrically provided with four first magnets 107, the positions of the first magnets 107 correspond one-to-one with the positions of the first through holes 106, the interior of the female head body 102 is symmetrically provided with four channels 108 connected with the first opening 103 and electromagnetic coils 109 surrounding the channels 108, the opening positions of the channels 108 correspond one-to-one with the positions of the first through holes 106, and the channels 108 are provided with second magnets 110 and ejection rods 111; the side of the second connection mechanism 205 is symmetrically provided with four second through holes 210. Through the above arrangement, the present invention can further increase the stability of the automatic connection device and prevent the male head and the female head from falling off.

[0033] Furthermore, in order to allow the second connection structure to enter the first opening and form a connection with the first connection structure, a third opening 211 is provided on the second connection structure 205, and the width of the third opening 211 is greater than the width of the first connection structure 104.

Further, the outer wall of the first connection mechanism 104 is provided with a load-bearing steel channel 7.
