Close, by second switch 55, motor 700 can be opened and closed conveniently conducive to realizing, so as to more in due course, it is convenient open with
Motor 700 is closed, it is easy to operate, also it is conducive to save electric energy.Wireless telecommunications are used between auxiliary handle component and power tool, it is auxiliary
Helping handle assembly further includes the first wireless communication module 56, the battery (not shown) to the power supply of the first wireless communication module 56, electricity
Road plate 59, the first wireless communication module 56 are set to circuit board 59, and circuit board 59 can be fixed by screws in auxiliary handle group
Inside part, second switch 55 and the first wireless communication module 56 are electrically connected, and battery uses button cell, and button cell voltage is
3.3 volt.Power tool is equipped with corresponding the second wireless communication module 72 with 56 wireless telecommunications of the first wireless communication module.First opens
Closing 71 has first state, the second state, the third state, and different states corresponds to different gears, first state, the second shape
State, the third state correspond to motor is normally opened, motor often closes, second switch 55 control, specifically, first switch 71 is in first state
When motor 700 open, motor 700 is closed when first switch 71 be in the second state, electric when first switch 71 is in the third state
Machine 700 is opened and closed by second switch 55.Second switch 55 can be button switch, rocker switch or slide switch.At this
Second switch 55 is a kind of button switch in embodiment, and first switch 71 is a kind of rocker switch (rocker switch another kind call
For ship type switch), the master switch of case EP3222386A is a kind of slide switch before the application.Since button switch, wraping plate are opened
It closes or slide switch is all existing common switchtype, the innovative point of the application does not lie in first switch 71, second switch yet
55 structures itself, therefore repeat no more.
To illustrate control process using the first switch 71 of rocker switch in present embodiment: first switch 71
(ginseng Figure 13) has mark "-", " 0 ", "=", and first switch 71 is first state when first switch 71 gets to "-" position, and first
First switch 71 is the second state when switch 71 gets to " 0 " position, and first switch 71 is when first switch 71 gets to "=" position
The third state；Figure 22 to Figure 26 is correlation circuit diagram.Join Figure 22: first switch 71 is to inductive switch S1, when switch S1 is no and it
His contact connects then first switch 71 and corresponds to the second state, and the positive terminals (i.e. BAT+) of battery pack 73 are not accessed at this time
In circuit, therefore motor 700 is in close state；Switch S1 be connected to two contact a be corresponding first switch 71 be first state, open
Close S1 be connected to two contact b be corresponding first switch 71 be the third state.Join Figure 25, the both ends of motor 700 if metal-oxide-semiconductor Q6 conducting
Circuit communication is opened to motor 700, if two end loops of metal-oxide-semiconductor Q6 not general rule motor 700 are obstructed to which motor 700 is closed,
Metal-oxide-semiconductor Q6 conducting needs " VAC FET ON " termination high level (being exemplified as 3.3 volts) and " VAC FET OFF " to terminate low level
(being exemplified as zero potential)；When switch S1 is connected to two contact a, the end AUTO is not grounded (ground connection connects zero potential), power at this time
The end the AUTO voltage that the control chip (model R5F1026AASP, be set within fuselage) of tool detects still is 3.3 volts,
Therefore assert that first switch 71 is first state, then control chip gives the end " VAC FET ON " high level and (is exemplified as 3.3
Volt) and end low level (being exemplified as 0 volt) " VAC FET OFF ", thus triode Q2 conducting, triode Q3 conducting, triode Q1
Obstructed, metal-oxide-semiconductor Q6 conducting, and then motor 700 is opened；When switch S1 is connected to two contact b, the end AUTO is grounded and becomes zero at this time
Current potential, control chip detect that the end AUTO is zero potential and assert that first switch 71 is the third state, at this time can be by the
Two switches 55 (the switch S2 in corresponding diagram 23) open and close motor 700；First switch 71 is that one is often pressed under the third state
Secondary second switch 55, the state of motor 700 can change once: become closing from unlatching or become opening from closing, specifically:
Second switch 55 is pressed to which S2 is connected, the first wireless communication module 56 connects button cell (corresponding marked as B), after energization
First wireless communication module 56 sends signal to the second wireless communication module 72, and the second wireless communication module 72 passes through the end REMOTE
Control chip is fed back to, control chip is that can control the motor 700 closed before this to open, and process is with as before: passing through " VAC
FET ON ", which is terminated, to be terminated into high level and " VAC FET OFF " into low level, so that triode Q2 is connected, triode Q3 is connected,
Triode Q1 is obstructed, and then metal-oxide-semiconductor Q6 is connected, so that motor 700 is opened, hereafter to close motor 700, then presses the again
Two switches 55, S2 is again switched on, so that the first wireless communication module 56 sends signal to the second wireless communication module 72 after being powered,
Second wireless communication module 72 feeds back to control chip by the end REMOTE, and control chip holds " VAC FET ON " by high level
Switch to low level and hold " VAC FET OFF " by low level switch to high level, thus triode Q2 is obstructed, triode Q3 not
Logical, triode Q1 conducting, and then metal-oxide-semiconductor Q6 is obstructed, therefore 700 both ends of motor do not constitute power circuit, the power-off of motor 700 is closed
It closes；First wireless communication module 56, the second wireless communication module 72 can be used as radio receiving transmitting module use respectively, and first is wireless
Same wireless module can be used in communication module 56, the second wireless communication module 72, and (it is rich to originate from Shenzhen by model DL-bk24K6
Core company), it should be noted that controlling chip, first due to the electronic component that control chip, wireless module all right and wrong are usually advised
Wireless communication module 56, the second wireless communication module 72, which can according to need, replaces with other control chips and wireless module；
In addition, itself can serve as control chip since the wireless module having has stronger operational capability and use, therefore can save
Fall individually control chip, the second wireless communication module 72 can serve as control chip in the application.Electricity shown in the application
Road is also only a kind of citing, it is clear that can readily build different various electricity with other people of custom circuit knowledge
Road is also able to achieve the circuit function of the application.
