Abstract
The invention provides a voltage control device applied to an electric tool. The voltage control device comprises a detection module which is connected with the power supply input end of the electric tool, a voltage regulating module which is connected with a power supply and the power supply input end of the electric tool, and a control module which is connected with the detection module and the voltage regulating module. The detection module detects whether the electric tool is overloaded. When the electric tool is overloaded, the control module controls the voltage regulating module to turn down the voltage input into the power supply input end of the electric tool, so that the electric tool cannot normally work. When the turning down duration of the voltage input into the power supply input end of the electric tool reaches set time, the control module controls the voltage regulating module to regulate the voltage input into the power supply input end of the electric tool, so that the electric tool normally works. Compared with a power-off protection mode, the voltage control device has the advantages that by turning down the work voltage, the electric tool is protected; frequent shutdown and restart are not needed; and the use of the electric tool is convenient.

Above-mentioned voltage-operated device makes electric tool cisco unity malfunction by turning down the operating voltage of electric tool, and protects electric tool and power supply.With respect to the mode of power-off protection, turn down the mode of operating voltage without frequent cycle power, thereby bring convenience to the use of electric tool.
Brief description of the drawings
Fig. 1 is the voltage-operated device circuit diagram of an embodiment.
Embodiment
Please refer to Fig. 1, an embodiment provides a kind of voltage-operated device for electric tool.This voltage-operated device comprises the detection module 110 being connected with the power input of electric tool, the Voltage Regulator Module 120 being connected with the power input of power supply and electric tool and the control module 130 being connected with Voltage Regulator Module 120 with detection module 110.Detection module 110 detects electric tool and whether occurs overload, in the time there is overload in electric tool, control module 130 is controlled Voltage Regulator Module 120 and is turned down the voltage of power input of input electric tool electric tool cannot normally be worked, in the time that the duration that the voltage of power input of input electric tool is turned down reaches setting-up time, control module 130 is controlled Voltage Regulator Module 120 and is adjusted the voltage of the power input of input electric tools electric tool is normally worked.Overload herein comprises that the operating current of electric tool is excessive, motor speed is too low, Motor torque is excessive.In this embodiment, be that transshipping appears in whether excessive the judging whether of operating current of utilizing detection module 110 to detect electric tool.
Setting-up time herein can be set according to actual needs, and for example, setting-up time can be 1 to 10 second.In this embodiment, setting-up time is 3 seconds.
Like this, only have electric tool not occur overload, when the phenomenons such as operating current is excessive, motor speed is too low, Motor torque is excessive do not appear in electric tool, this electric tool could normally be worked; Otherwise the voltage of the power input of electric tool will constantly be turned down because electric tool occurs overload, thereby electric tool cannot normally be worked all the time.So just can reach the object of protection electric tool and power supply.
This voltage-operated device also comprises cell voltage acquisition module 160, and power supply is herein battery.Cell voltage acquisition module 160 is connected with power supply.Whether cell voltage acquisition module 160 is abnormal for detection of the voltage of power supply.For example, in the time that cell voltage acquisition module 160 detects the brownout of power supply, control module 130 is controlled Voltage Regulator Module 120 and is turned down the voltage of power input of input electric tool electric tool cannot normally be worked.Thereby preventing that battery from crossing puts, reach the object of protection power source.
In this embodiment, the control module 130 of this voltage-operated device is microprocessor unit circuit.Voltage Regulator Module 120 is DC-DC power module.Detection module 110 is used for gathering the voltage of electric tool.This voltage-operated device also comprises 5V power module 140.This 5V power module 140 is mainly used in powering for control module 130.
When work, cell voltage acquisition module 160 and detection module 110 gather respectively the voltage of power supply and the voltage of electric tool and by the voltage transmission collecting to control module 130.Control module 130 judges that whether the voltage of the power supply collecting operating current whether too low or electric tool is excessive, when the brownout of power supply or the operating current of electric tool are when excessive, control module 130 cannot normally work electric tool the voltage of controlling Voltage Regulator Module 120 and turn down the power input of input electric tool.The duration of being turned down when the voltage of power input of input electric tool reaches setting-up time, and when the voltage of the power supply that cell voltage acquisition module 160 collects is normal, the voltage that control module 130 is controlled the power input of Voltage Regulator Module 120 adjustment input electric tools is normally worked electric tool.And when for no other reason than that the operating mode frequent variations of electric tool while occurring that the operating current of electric tool is excessive; this voltage-operated device can be realized and turn down fast voltage electric tool is protected; and the fast quick-recovery of electric tool is normally worked, and avoid frequently restarting, shorten start-up time.Rapid boot-up time is herein setting-up time, is 3 seconds herein.
This voltage-operated device makes electric tool cisco unity malfunction by turning down the operating voltage of electric tool, protects electric tool and power supply.Adopt the mode of power-off protection electric tool with respect to traditional circuit control device for electric tool, turn down the mode of operating voltage without frequent cycle power, thereby bring convenience to the use of electric tool, and saved the time.Therefore, this voltage-operated device has advantages of at electric tool and occurs still making electric tool easy to use under the frequent condition of working conditions change.
The above embodiment has only expressed several execution mode of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection range of patent of the present invention should be as the criterion with claims.
