Description
Technical field
The utility model relates to charging device, particularly can to power consumption equipments such as robot automatically, the charging device of quick charge.
Background technology
Power consumption equipments such as robot, for example intellective dust collector etc. normally relies on the storage battery power supply that himself carries; Because the electric weight of storage battery is limited; And the mechanical device of the control system of power consumption equipments such as robot, drive unit and direct execution work task all needs consumed power in the process of work, therefore, and once after the charging; How long power consumption equipment has worked not usually, just needs charging once more.In the past, the charging of power consumption equipment was accomplished through manual work.Method with artificial charging no doubt can solve the charging problem of power consumption equipment, but is unfavorable for saving human resources.Particularly under the situation that nobody in time charges for power consumption equipment, power consumption equipment can can't operate as normal because of the consumption of electric energy.In order to save human resources and to improve the operating efficiency of power consumption equipment, people carry out the improved while in the control system to power consumption equipment, have invented the charging device to power consumption equipments such as robots.At present, the technical scheme of realization power consumption equipment charging is roughly following:
In charging device, be provided with infrared charging pilot signal device, linear transformer and corresponding charging circuit---linear power supply circuit thereof; In the operating time of power consumption equipments such as robot, said infrared charging pilot signal device outwards sends infrared charging pilot signal incessantly; In the control system of power consumption equipment, be provided with electric quantity detection apparatus and infrared information receiving system; When the voltage of the entrained storage battery of power consumption equipment be greater than or equal to its normal working voltage following in limited time; Said infrared information receiving system cuts out; When the voltage of said storage battery be lower than its normal working voltage following in limited time; Said electric quantity detection apparatus can be sent to voltage signal the terminal control module of power consumption equipment, and said terminal control module will instruct power consumption equipment to quit work, and sends open command to said infrared information receiving system; After said infrared information receiving system is opened, just can receive the infrared charging pilot signal that charging device sends.Under the guiding of infrared charging pilot signal, said terminal control module can be sent instructions such as advancing, retreat, turn to the drive system of robot, makes power consumption equipment find charging device.When the charging electrode of power consumption equipment with after the charging electrode of charging device docks, charging device will be given the entrained charge in batteries of power consumption equipment, meanwhile, its infrared information receiving system can cut out automatically.After the electric weight of the storage battery of power consumption equipment was full of, said electric quantity detection apparatus can be sent to the information that electric weight is full of the terminal control module of power consumption equipment, and said terminal control module just can be sent instruction, drove power consumption equipment and broke away from charging device.In addition, with regard to helping the specific target of power consumption equipment searching, prior art also discloses the technical scheme that adopts other guiders such as Hall element, photoelectric sensor except adopting infrared sensor.
