The intelligent pen with the trigger switch structure comprises any one of the pen trigger switch structures, the trigger switch structure is arranged in the intelligent pen corresponding to the signal transmitter and the signal receiver, a circuit board and a power supply 10 are sequentially arranged behind the trigger switch structure, and a metal dome 3 and a processor 6 are arranged on the circuit board; when the pen point 2 writes, the generated pressure is transmitted to the metal dome 3, and the processor 6, the signal transmitter 4 and the signal receiver 5 are started; the signal emitter 4 emits a detection signal to the object to be detected around the pen point 2; a signal receiver 5 for receiving a detection signal reflected from the object to be measured and generating image data; the processor 6 is connected with the signal receiver 5, receives the image data sent by the signal receiver 5, analyzes the image data into digital signals and generates transmission data packets; and the wireless data interface 72 is connected with the processor 6 and transmits the transmission data packet to an upper computer in a wireless mode.
As shown in fig. 2 and 3, the smart pen includes: the pen comprises a pen shell 1, a pen point 2, a metal dome 3, a signal transmitter 4, a signal receiver 5, a processor 6 and a wireless data interface 72.
The pen case 1 may be made of engineering plastic, and generally includes two pen cases which can be fastened together, and other devices are accommodated in the pen case 1.
The pen point 2 extends from the pen shell, and the pen point 2 is used for writing, namely generating strokes and orders, and can be written on paper or a whiteboard. If for writing on a paper surface, the nib may be a pencil nib, a rewritable (ink-decomposed) nib, a rewritable (ink-cured) nib, a plastic (PP, PET, PVC, etc.) nib, or the like. If the writing is written on the white board, the white board can be a handheld white board or a white board externally hung and adhered on the wall surface.
The metal dome 3 is connected with the spring thimble 203, pressure generated when the pen point 2 writes is transmitted to the metal dome 3, the metal dome 3 is used as an electric connection structure of the circuit board, when a force is applied, the circuit is conducted, and the circuit is closed after the force disappears; which functions as an activation shutdown processor 6, signal transmitter 4 and signal receiver 5.
For example, when writing on a paper surface, since the paper surface is elastically compressible, the sensitivity of the snap dome 3 needs to be high, otherwise it is impossible to recognize that the pen tip 2 is writing. When the intelligent pen is used for writing on the whiteboard, the whiteboard is hard and has small elasticity, so that the sensitivity of the metal dome can be slightly small, and the pen point 2 can be identified to write, so that the metal dome provided with the hollow part and the swing arm can be subjected to a force of 15g or below 15g, and the intelligent pen can be started sensitively.
The signal emitter 4 is connected with the pressure sensor 3 and emits a detection signal to the object to be detected around the pen point. When the dome 3 senses the pressure of the pen point 2, the circuit of the circuit board is communicated, and the signal emitter 4 starts to work to emit signals. The signal generator 4 may be a transmitter that transmits sound waves, ultrasonic waves, infrared rays, ultraviolet rays, visible light (each band), X-rays, gamma rays, or the like.
Optionally, the signal emitter 4 emits the detection signal in various ways, specifically, in a continuous or fixed frequency or variable frequency or frequency modulation way, to emit the detection signal to the object to be detected around the pen point.
The signal receiver 5 receives the detection signal reflected from the object to be measured, and generates image data. The image data at this time is an analog signal. The signal receiver 5 needs to be matched with the signal transmitter 4 to receive the detection signal reflected from the object to be measured. Because the signal transmitter 4 transmits a detection signal to the object to be measured around the pen point 2, the signal receiver 5 generates an image of the object to be measured around the pen point 2. When the dome 3 senses the pressure of the writing of the pen point 2, the circuit of the circuit board is communicated, the signal receiver 5 starts to work, the detection signal reflected by the object to be detected is received, and the analog image data is generated.
The processor 6 is electrically connected with the metal dome 3 and the signal receiver 5, receives the image data sent by the signal receiver 5, analyzes the image data into digital signals and generates a transmission data packet. When the dome 3 senses the pressure of writing by the pen point 2, the processor 6 starts to work, processes the received analog image data into the data of a digital signal, and then generates a transmission data packet.
The wireless data interface 72 is connected to the processor 6 and transmits the transmission data packet to the upper computer in a wireless manner. The wireless data interface 72 is used for transmitting data packets to the upper computer in a wireless manner, which is convenient and does not require cable connection.

In another non-real-time transmission mode, the processor 6 analyzes the image data into digital signals in real time, encodes the digital signals with a clock and a time axis into standard transmission data packets in real time, stores the standard transmission data packets in the memory 8, and transmits the transmission data packets stored in the memory 8 to an upper computer through the wireless data interface 72 at set time or in other non-real-time modes.
The power supply 10 is connected with the metal dome 3, the processor 6, the signal transmitter 4 and the signal receiver 5. The purpose of the power supply 10 is to supply power to the processor 6, the signal transmitter 4 and the signal receiver 5 via the dome sheet 3.
