When the radio receiving module and the radio transmitting module are in contraposition contact, the distance between the first butt joint surface and the second butt joint surface is between 0 and 20 mm.
Referring to fig. 4 and 5, fig. 4 and 5 are a side view and a top view of the wireless charging system in a charging state, respectively. When the electric quantity detection module of the self-propelled device 10 detects that the electric quantity of the internal battery pack is lower than the preset electric quantity, the control module controls the driving module to drive the walking assembly to operate, and the self-propelled device 10 automatically searches for the wireless charging station 20 (provided with the navigation module and capable of automatically navigating). At this time, the control module simultaneously cuts off the connection with the sensing assembly and controls the driving module to continuously provide the driving force to the walking assembly 12. After the wireless charging station 20 is found, the base 21 is inserted between the traveling wheel sets of the self-propelled device 10, after the wireless receiving module at the bottom of the self-propelled device 10 is in contact with the base 21, under the action force of the traveling component 12 and the abutting force of the base 10, the self-propelled device 10 climbs upwards along the guide surface 211 of the base 21, the front end of the self-propelled device 10 is jacked up, at this time, because the control module cuts off the contact with the induction component, the lifting protection mechanism of the self-propelled device 10 fails, the driving module continues to provide driving force for the traveling component 12 until the wireless receiving module at the bottom is sufficiently close to the wireless transmitting module on the base 21 and starts to be aligned and contacted, the driving module cuts off the provision of the driving force, and the self-propelled device 10 starts to be charged.
