Referring to fig. 1, 2 and 4, an embodiment of the present disclosure provides a cleaning robot, including a charging base 100 and a robot body 200, where the charging base 100 includes a power supply unit 120 and a discharge unit 124 electrically connected to the power supply unit 120, and the robot body 200 includes a power storage unit (not shown) and a power taking unit 230 electrically connected to the power storage unit. When the robot body 200 moves to the charging seat 100, the power taking part 230 is connected to the discharging part 124 in an absorbing manner. The discharging portion 124 and the power-taking portion 230 both have a conductive surface M, and when the power-taking portion 230 and the discharging portion 123 are connected in an absorption manner, the conductive surface M of the discharging portion 124 and the conductive surface M of the power-taking portion 230 are at least partially overlapped, so that the power supply portion 120 supplies power to the power storage portion.

When the electric quantity of the power storage part in the robot body 200 is insufficient, the robot body 200 moves to the charging stand 100, and when the robot body 200 moves to the charging stand 100, the power take-up part 230 thereon is connected to the power discharge part 124 in an adsorbing manner. When the power-taking portion 230 is connected to the discharging portion 124 in an absorption manner, the conductive surface M on the power-taking portion 230 and the conductive surface M on the discharging portion 124 are at least partially overlapped. When the two conductive surfaces M overlap, the power supply circuit between the power supply unit 120 and the power storage unit is turned on, so that the power supply unit 120 can supply power to the power storage unit. Compared with the scheme of conducting the power supply circuit in a point-to-point terminal mode in the prior art, the conducting of the power supply circuit can be realized as long as two conducting surfaces M are partially overlapped, the contact stability of the conducting surfaces M can be improved by the adsorption connection mode, even if errors exist in the positioning of the robot body 200, the two conducting surfaces M can be ensured to be reliably contacted and conduct the power supply circuit, the requirement on the positioning precision of the robot body 200 is greatly reduced, and the positioning cost of the robot body 200 is reduced.

It can be understood that, when the robot body 200 moves to the charging dock 100, the power-taking part 230 on the robot body 200 and the discharging part 124 on the charging dock 100 gradually approach each other. When the robot body 200 moves to the charging seat 100, the distance between the power taking part 230 and the discharging part 124 is within the adsorption distance, and the two parts can be in adsorption connection, that is, in the process that the robot body 200 moves to the charging seat 100, the power taking part 230 and the discharging part 124 are in adsorption connection.

In order to realize the suction connection between the power taking part 230 and the discharging part 124, in some alternative embodiments, the discharging part 124 and the power taking part 230 are connected by a negative pressure suction manner. Specifically, a negative pressure pump and a negative pressure pipeline are arranged in the charging seat 100, the discharging part 124 has a negative pressure hole, the negative pressure pipeline connects the negative pressure pump and the negative pressure hole, and when the discharging part 124 and the power taking part 230 are within the adsorption distance, the negative pressure generated by the negative pressure pump connects the discharging part 124 and the power taking part 230 in an adsorption manner. Further, a sensor is arranged on the charging seat 100, a sensing part matched with the sensor is arranged on the robot body 200, the sensor is in control connection with the negative pressure pump, when the sensor senses the sensing part, the sensor generates a first electric signal to the negative pressure pump, and the negative pressure pump responds to the electric signal and is started to generate negative pressure. When the sensor cannot sense the sensing part and cannot generate a first electric signal, the negative pressure pump closes the negative pressure. Therefore, the position of the robot body 200 is monitored through the sensor, and the negative pressure pump is controlled to be started when the power taking part 230 and the discharging part 124 are in the range of the adsorption distance, so that the energy loss is reduced. Of course, the schemes in the following examples can also be adopted.

Specifically, power taking unit 230 and the power storage unit may be electrically connected by a wire, and discharging unit 124 and power supply unit 120 may also be electrically connected by a wire.

Specifically, the first magnetic member may have a first magnet and a first conductive portion wrapped outside the first magnet, the second magnetic member may have a second magnet and a second conductive portion wrapped outside the second magnet, the first conductive portion may be electrically connected to the power storage portion, the second conductive portion may be electrically connected to the power supply portion 120, the first magnet and the second magnet may attract each other, and when the first magnet portion and the second magnet portion are within an attraction range, a magnetic attraction force may be generated so that the first conductive portion and the second conductive portion are connected to each other. Thus, the attractive force between the first magnet and the second magnet is utilized to realize the adsorption connection between the first conductive part and the second conductive part, and further electric quantity transmission is realized. The first conductive part and the second conductive part may be conductive metal sheets, such as copper sheets or iron sheets.

The conductive magnet member may be an iron-boron powerful magnet member, a permanent ferrite magnet member, a samarium-cobalt magnet member, and an alnico magnet member. The magnetic member may be a conductive magnet member, may also adopt a structural manner such as the first magnetic member and the second magnetic member, and may also be a metal member, which is not limited herein.
