Detailed description of the invention
Below in conjunction with accompanying drawing, the technical solution of the utility model is carried out clear, complete description, it is clear that described enforcement
Example is a part of embodiment of the present utility model rather than whole embodiments.Based on the embodiment in this utility model, ability
The every other embodiment that territory those of ordinary skill is obtained on the premise of not making creative work, broadly falls into this practicality new
The scope of type protection.
Embodiment one
As it is shown in figure 1, the switch main body device for testing functions of DC high-power electric tool, including electronic signal process module,
Match circuit and instruction device,
Described match circuit, including power outlet, is used for connecting external direct current power supply and powers to switch main body test device；Even
Wiring bundle, connection indication device and measured switch；
Described instruction device, is connected with measured switch, is used for indicating whether measured switch is connected, and by instruction device during detection is
No operating judges.
Described electronic signal process module, connects measured switch, and according to the output signal of measured switch, output services signal is to treating
Slowdown monitoring switch.
The switch main body device for testing functions of the DC high-power electric tool of embodiment one, first will test device and measured switch master
Body portion, external direct current power supply connect, wherein, external direct current power supply by power outlet respectively with electronic signal process mould
Block and measured switch main body connect, and power for electronic signal process module and measured switch main body；Instruction device and measured switch master
M+ and M-of body is connected by rat tail；Electronic signal process module connects measured switch, according to the measured switch detected
Output signal, output services signal is to measured switch.Operator opens DC source, and presses the hands of measured switch main part
Whether handle, can be run well by observation instruction device and judge that the basic function of measured switch main body is the most normal.If it is to be measured
Switch main body function is normal, then can be signaled to electronic signal process module, and electronic signal process module is defeated according to this signal
Go out working signal to be given to measured switch main body and be turned on, after connection, then indicate device to start running；If switch main body function is the most just
Often, instruction device cannot run well.During the switch main body of test different types, electronic signal process module can be according to receiving
The signal that sends of different switch main bodies, send different working signals and be given to switch main body, make switch main body connect and start working.
Embodiment two
The switch main body device for testing functions of DC high-power electric tool based on embodiment one, described electronic signal process module,
Including power supply interface module, single-chip microcomputer (MCU), signal deteching circuit (as shown in Figure 2), described power supply interface module, connect
Connect single-chip microcomputer and power outlet, and there is DC/DC circuit (DC/DC conversion circuit), for by external direct current power supply
Voltage is converted into circuit and supplies voltage to single-chip microcomputer work power supply；Described single-chip microcomputer, according to the output signal of measured switch main body,
Output services signal, to measured switch main body, makes measured switch main body connect；Described signal deteching circuit is to pass through signal transmssion line
Bundle connects signal input/output interface and the measured switch main body of single-chip microcomputer, passes for the output signal sent by measured switch theme
It is defeated by single-chip microcomputer, and the working signal of single-chip microcomputer is transferred to measured switch main body.
The switch main body device for testing functions of the DC high-power electric tool of embodiment two, will test device and measured switch main body
Partly, after external direct current power supply connects, during test, external voltage is converted into 5V D/C voltage and flows to list by DC/DC circuit
Sheet machine, single-chip microcomputer connects measured switch main body by signal transmssion line bundle, and single-chip microcomputer accepts different measured switch main body and sends not
Same signal, can send and have the most different working signals and be given to measured switch main body and make switch connection start working.
As a example by Switch A series switch (as shown in Figure 2 and Figure 3), between single-chip microcomputer and measured switch, the signal of transmission is main
Having two kinds, a kind of is the Wake Up signal less than 5V having measured switch main body to be sent to single-chip microcomputer, and single-chip microcomputer receives Wake
The Control square-wave signal of 20ms Low 20ms High can be sent from MCU PIN during Up signal and be given to measured switch main body,
Now switch receives this signal and just can start working.
Again as a example by Switch B series switch (as shown in Figure 2 and Figure 3), wherein 3pin is Tool ID to measured switch main body,
Battery ID, and tri-kinds of signals of Shut Down: Tool ID is that the MOTOR of switch identifies that signal is to be issued by test module
Main body switch single-chip microcomputer, because the running voltage of different Motor is had any different, when Tool ID detects that different magnitudes of voltage can call
Different software in main body switch makes switch.The signal of Battery ID is similarly used for detecting different defeated from Tool ID signal
Go out the battery bag of voltage.Shut Down signal is the signal that single-chip microcomputer sends when detecting more than certain magnitude of voltage, and these three is believed
Number be given to measured switch main body just can make switch connection and work simultaneously.
Follow-up can being added in again according to the working condition of switch of signal for other series switch is tested in module, such as Battery
NTC signal, its function is the temperature of detection battery bag, and principle is the corresponding different temperature of different magnitudes of voltage, so battery to be made
Suitable magnitude of voltage can must be had by main body switch work, by test module single-chip microcomputer wherein 1pin by soft with normal power supply
Part regulation makes it also say as in temperature range in the range of operational voltage value.
Embodiment three
The switch main body device for testing functions of DC high-power electric tool based on embodiment one, described instruction device is motor,
During test, if motor runs well, then explanation measured switch main body can be connected and function is normal.When measured switch main body is double
When switch, after being completed the basic function in a direction, operative employee only needs the reversing bar again of toggle switch main part
Secondary switch knob of pressing, observes whether motor can rotate backward the Basic function testing that can complete another direction of two-way switch.
The indicative function of motor can also replace with other loads.
Embodiment four
The switch main body device for testing functions of DC high-power electric tool based on embodiment one, described switch main body test device,
Also include DC source.Switch main body test device can directly mate suitable DC source, by power outlet respectively with
Electronic signal process module and measured switch main body connect, and power to switch main body test device, use convenient.
In sum, the various embodiments described above and accompanying drawing are only preferred embodiment of the present utility model, not in order to limit this reality
