The present invention is a wired and wirelessly charged device. Since the wireless charging technology uses a well-known electronic device wireless charging system, the contents of the wireless charging system are omitted.

The power supply wiring 250, the main control unit 820, the motor 210 of the hand motor, and the motor RPM adjusting unit 830 of the hand motor are connected to each other. , And an LED lamp 850. [

In addition, a main control unit 820 incorporating a commonly known program control unit such as a 'micro controller art mega 128', a motor RPM adjustment unit 830 of a hand motor for adjusting the RPM of the motor, And an LED lamp 850 so that the operator can know the converted electricity value according to the situation.

A simple block and operation principle of a hand motor provided with an LED lamp are as follows.

First, electric power required for the motor RPM regulator of the hand motor is supplied through the power supply line 250, and when the RPM speed is adjusted together with the start of the motor 210, the main control unit 820 controls the electric signals to control the motor 210 operate.

Further, when the motor 210 is operated, electricity enters the main control unit 820. The electric power supplied to the main control unit is supplied to the hand motor program control unit 840, and the electric value dropped due to the frictional resistance rises when the RPM rotational speed is further increased.

At this time, the red LED lamp 850 lights up when electricity exceeding the proper value is passed, and the operator's force at this time means the load applied when the hand motor is pressed by 40 ~ 50N in the alveolar bone drilling operation.

Also, the red LED lamp 850 is lit, which indicates that the operator has a lot of pressing force in the implant operation with the temperature rise due to frictional resistance between the tooth and the hand motor drill.

In the alveolar bone drilling operation, since the load on the drill is zero during the operation of the operator, the resistance value also becomes '0', and the yellow LED lamp 850 is lit through the incoming electricity.

At this time, the operator indicates that the pressing force of the hand motor in the alveolar bone drilling operation is performed without the teeth and the hand motor drill being in contact with each other.

In addition, the blue LED lamp 850 lights up when the electricity of the proper value necessary for the operation is transmitted, and the operator's force at this time indicates that the hand motor is being operated with proper force of 30 ~ 40N in the alveolar bone drilling, And the temperature occurring between the drill is normal.

Meanwhile, a mechanical driving method of a hand motor for a procedure equipped with the LED lamp used in the present invention is as follows.

The hand motor head unit includes a cutout groove 310 for transmitting the power transmitted from the hand motor body 200 to the hand motor head unit, An intermediate shaft for transmitting power to the intermediate shaft, and a rotating shaft for transmitting power to the driver.

The reduction gear unit for connecting the rotational force, which is the power of the motor, to the hand motor head unit includes an input pinion gear, an output pinion gear, a left center shaft, a center center shaft, a right center shaft, A center stop power transmission gear, and a right upper power transmission gear.

’이며, 좌측하단에 위치한 동력전달기어는 좌측하단 동력전달기어(232)라 한다.In addition, the shape of the vertical cross section of the power transmission gear is'

And the power transmission gear located at the lower left end is referred to as the lower left power transmission gear 232.

The center interrupted power transmission gear 233 and the right upper end power transmission gear 234 have the same vertical cross section as the left lower end power transmission gear and correspond to the power transmission gear.

Each of the power transmission gears is divided into an upper gear and a lower gear. The lower left power transmission gear 232 is composed of an upper gear 232-1 and a lower gear 232-2 of the lower left gear, The central intermittent power transmitting gear is composed of an upper gear 233-1 and a lower gear 233-2, and the upper right power transmission gear is composed of an upper gear and a lower gear of a right upper gear.

The left lower power transmission gear 232 rotates in conjunction with the left center shaft 237 and the center intermediate power transmission gear 233 rotates in conjunction with the central center shaft and the right upper power transmission gear 234 is rotated And rotates in conjunction with the shaft.

The power transmission process of the reduction gear unit is as follows.

First, the rotational force, which is the power of the motor 210, is transmitted to the intermediate shaft 220 of the hand motor, and the rotational force of the intermediate shaft is transmitted to the input pinion gear 231.

The rotational force transmitted to the input pinion gear transmits a rotational force to a left lower end power transmission gear 232 coupled to a left center shaft of the reduction gear unit 230. The left lower end power transmission gear transmits a rotational force to a center And transmits the rotational force to the intermediate power transmission gear 233, which transmits the rotational force to the right upper power transmission gear 234 coupled to the right center shaft.

’이며, 기어비에 의해 감속되는 과정은 다음과 같다.The vertical cross-sectional shape of the power transmission gear of the reduction gear unit is "

And the process of decelerating by the gear ratio is as follows.

First, the rotational force transmitted to the input pinion gear 231 transmits a rotational force through the lower gear 232-2 of the lower left power transmission gear 232.

At this time, since the diameter of the lower gear 232-2 of the lower left power transmission gear 232 is larger than the diameter of the input pinion gear 231, when the power is transmitted, the speed is decreased and the torque is increased.

The rotational force of the upper gear 232-1 of the lower left power transmission gear 232 is transmitted to the lower gear 232-2 of the center interrupted power transmission gear 233.

Since the diameter of the lower end gear 232-2 of the central interrupted power transmission gear 233 is larger than the diameter of the upper gear 232-1 of the lower left power transmission gear 232, the speed is once again reduced , The torque increases again.

The rotational force of the upper gear 232-1 of the central interrupted power transmission gear 233 is transmitted to the lower gear 232-2 of the right upper power transmission gear 234.

The diameter of the lower gear 232-2 of the upper right power transmission gear 234 is larger than the diameter of the upper gear of the center interrupted power transmission gear 233 as in the preceding reduction gear intervals, More deceleration, torque increases once again.

Then, the rotational force transmitted to the upper gear 232-1 of the upper right power transmission gear 234 is transmitted to the output pinion gear 235. Finally, similarly to the preceding deceleration sections, the right upper power transmission gear The output pinion gear 234 is larger in diameter than the upper gear diameter of the pinion gears 234 and 234, so that when the power is transmitted, the speed is finally reduced again and the torque increases again.

The finally increased torque is transmitted to the hand motor head unit 300 by the engagement bar connected to the upper center shaft.

When the hand motor of the present invention is decelerated by the speed reducer unit, a higher torque is increased at the same RPM, so that a safer operation can be performed than the existing operation.
