Fig. 4 illustrates a schematic structural view of a second housing of the charging module shown in fig. 2.

In some embodiments, the second housing 12 includes a body 120 and two position-limiting portions 121 extending from the body 120 toward the first housing 11, each position-limiting portion 121 is provided with a first positioning hole 1211 for allowing the guide pillar 142 to pass through, the switch element 13 is disposed on a side of the position-limiting portion 121 away from the first housing 11, and in the first state, a side of the charging seat 141 facing the guide pillar 142 abuts against the position-limiting portion 121.

As shown in fig. 4, in the first state, when the charging seat 141 abuts against the position-limiting part 121 at a side facing the guide post 142, the elastic element 140 is compressed to a limit or a large amount of compression, and the charging seat 141 moves towards a side away from the opening 111 to drive the guide post 142 to pass through the first positioning hole 1211 and abut against the switch element 13, so that the switch element 13 is turned on to send an electrical signal. Meanwhile, the elastic element 140 generates a large elastic force to the charging base 141, so that the charging sheet 144 at one end of the charging base 141 is in close contact with the elastic sheet 23 to be charged.

As shown in fig. 5, one end of the swing link 131 of the micro switch, which is close to the guide post 142, is connected to the micro switch, and the other end is a free end, when the charging stand 141 is in the first state, the guide post 142 is pushed by an external force to extend out of the first positioning hole 1211, and the swing link 131 is pushed to rotate, and the swing link 131 presses the corresponding movable contact in the rotating process, so that the movable contact is in contact with the fixed contact. In the second state, the guide post 142 is withdrawn from the swing link 131 for resetting, and the swing link 131 and the corresponding movable contact thereof are reset, so that the movable contact is disconnected from the fixed contact.

In some embodiments, the switch member 13 is a correlation photoelectric switch, and includes a transmitting end and a receiving end, which are oppositely disposed, and in the first state, the charging seat 141 pushes the guide post 142 to extend out of the first positioning hole 1211 and enter between the transmitting end and the receiving end under the action of external force, so that the switch member 13 sends an electrical signal.

In the first state, the guide post 142 protrudes from the first positioning hole 1211 and enters between the emitting end and the receiving end, and blocks the light between the emitting end and the receiving end, so that the light can be converted into a change of current to generate an electrical signal. In the second state, the guide post 142 is withdrawn from between the emitting end and the receiving end, and cannot block the light between the emitting end and the receiving end, so that an electrical signal cannot be generated.

In one example, the circuit board assembly 15 includes a delay module, the delay module sends an electrical signal to the control module 21 of the motherboard assembly 2 after a preset time delay after the switching element 13 is turned on, and then the control module 21 controls the power module 22 to supply power to the charging pad 144. In another example, the motherboard assembly 2 includes a delay module, the electrical signal generated by the switch 13 is sent to the circuit board assembly 15, the circuit board assembly 15 sends the electrical signal to the control module 21 of the motherboard assembly 2, and the control module 21 delays a preset time through the delay module after receiving the electrical signal and then controls the power module 22 to supply power to the charging pad 144.

In addition, the pair of charging sheet assemblies 14 are designed to be fool-proof through the cooperation between the first plane P1 disposed on the positioning column 143 and the second plane P2 disposed corresponding to the second positioning hole 1212, so as to prevent the first harness 18 from being led out due to confusion between the positions of the positive charging sheet 144 and the negative charging sheet 144, or the length of the first harness 18 is not enough to be led out to the main board assembly 2 after the position of the first harness 18 is exchanged.

In some embodiments, either one of the first housing 11 and the second housing 12 is provided with a snap, and the other one of the first housing 11 and the second housing 12 is provided with a snap groove that mates with the snap.

As shown in fig. 1, the first housing 11 is provided with a buckle 112, the second housing 12 is provided with a slot 122 matched with the buckle 112, the number of the buckles 112 and the slots 122 can be multiple, and thus, the quick detachment and assembly between the first housing 11 and the second housing 12 can be realized through the clamping connection.

The following describes the technical solution provided in this embodiment with reference to a specific application scenario.

As shown in fig. 1 and 5, embodiments of the present application provide a base station for providing power to a self-moving device such as, but not limited to, a sweeping robot, a mowing robot, and the like. The base station comprises a charging module 1 and a mainboard assembly 2, and the mainboard assembly 2 comprises a control module 21 and a power supply module 22. For convenience of description, the sweeping robot is taken as an example for explanation in the present application.

When the power of the sweeping robot is insufficient, the sweeping robot needs to return to the base station for charging. After the sweeping robot reaches the base station, the elastic sheet 23 to be charged is in butt contact with the charging sheet 144 of the charging module 1 of the base station, so as to generate a thrust force on the charging seat 141 of the charging module 1, and the charging seat 141 pushes the guide pillar 142 to extend out of the second shell 12 and turn on the switch 13 under the action of the thrust force. Specifically, the switch element 13 is a micro switch, the guide post 142 extends from the second housing 12 and pushes the swing link 131 of the micro switch to rotate, and the swing link 131 presses the corresponding movable contact in the rotating process, so that the movable contact is in contact with the fixed contact. After the switch 13 is turned on, the first electrical signal is sent to the control module 21 of the motherboard assembly 2, and after the control module 21 receives the first electrical signal, a preset time is delayed, and then the power module 22 is controlled to supply power to the charging sheet 144.

After the mobile device is charged, the mobile device leaves the base station, the spring sheet 23 to be charged is not in contact with the charging sheet 144, the guide post 142 is reset through the elastic element 140 and disconnects the switch element 13, at this time, the guide post 142 is withdrawn from the swing rod 131 for resetting, and the swing rod 131 and the corresponding movable contact thereof are reset, so that the movable contact is disconnected from the fixed contact. The switch element 13 then sends a second electrical signal to the control module 21 of the motherboard assembly 2, so that the control module 21 receives the second electrical signal and then controls the power module 22 to be powered off, and no longer supplies power to the charging pad 144.

In this application, through increased time delay circular telegram function in the basic station, can prevent to charge piece 144 and wait to charge shell fragment 23 and take place to strike sparks in the twinkling of an eye of butt joint, avoid forming the oxide layer on the surface of charging piece 144 and lead to contact failure, improve the reliability of charging from mobile device.
