[0091] To better explain and facilitate understanding of the present invention, it is described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described below are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, unless otherwise specified, the embodiments and features described in the present invention can be combined with each other; for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.
[0092] See Figure 1 This embodiment provides a smart writing pen, which includes:
[0093] The inner liner assembly and the pen barrel 1 for housing the inner liner assembly.
[0094] See Figure 2 , Figure 3 , Figure 4 The inner lining assembly includes: inner lining 2, circuit board 3, and pen refill 4.
[0095] See Figure 2 The inner liner 2 includes, from left to right, a first mounting part 21, a first groove 22, a second mounting part 23, and a third mounting part 24; specifically, in this embodiment, the inner liner 2 is integrally formed.
[0096] The first mounting part 21 is equipped with a battery 5; the battery 5 is connected to the circuit board 3.
[0097] The second mounting section 23 is provided with a pen refill retainer 6 that is movable in the left-right direction; such as Figure 5 As shown, the pen refill fixing member 6 has a pen refill insertion hole 7 at its right end.
[0098] The third mounting section 24 is equipped with an infrared transmitter 8 and an ultrasonic transmitter 9, which are respectively connected to the circuit board 3.
[0099] The circuit board 3 covers the battery 5 and the pen refill holder 6 and is connected to the inner liner 2.
[0100] In practical applications, the circuit board 3 covers the battery 5 and the pen refill fixing member 6 and is connected to the inner liner 2 by means of threads or snap-fit.
[0101] The circuit board 3 is provided with a limit switch trigger unit 10; the limit switch trigger unit 10 corresponds to the first groove 22, and the left end of the pen refill fixing member 6 abuts against the limit switch trigger unit 10.
[0102] The pen refill 4 passes through the third mounting part 24 and is inserted from right to left into the pen refill insertion hole 7 on the pen refill fixing member 6. Specifically, the diameter of the pen refill insertion hole 7 is the same as the diameter of the pen refill 4, and the pen refill 4 can be inserted into the pen refill insertion hole 7 without wobbling.
[0103] In this embodiment, during the use of a smart writing pen, the inner liner assembly is housed in the pen barrel 1, wherein the pen tip protrudes from the head of the pen barrel. When the pen tip contacts the writing surface, pressure is generated at the tip of the pen tip. This pressure is transmitted through the pen tip to the pen tip fixing member 6, and the left end of the pen tip fixing member 6 touches the limit switch trigger unit 10 on the circuit board 3. The circuit board 3 then controls the infrared emitter 8 and the ultrasonic emitter 9.
[0104] See Figure 2 A perforated portion 25 is also included between the second mounting portion 23 and the third mounting portion 24 of the liner 2.
[0105] The perforated part 25 is provided with a through-hole tube 251.
[0106] The pen refill tail passes through the through-hole tube 251 inside the third mounting part 24 and the perforated part 25 from right to left and is inserted into the pen refill insertion hole 7 on the pen refill fixing member 6.
[0107] In practical applications, in order to prevent the pen refill 4 from shaking, the inner diameter of the through-hole tube 251 provided inside the perforated part 25 is also the same as the diameter of the pen refill. This can effectively fix the pen refill 4 so that the pen refill 4 will not shake during writing, thereby improving the writing effect.
[0108] See Figure 6 The third mounting part 24 includes a first pipe section 241 and a second pipe section 242 arranged coaxially.
[0109] The diameter of the first pipe section 241 is larger than that of the second pipe section 242.
[0110] One end of the first pipe segment 241 is connected to the second pipe segment 242.
[0111] The infrared emitter 8 is mounted on the first pipe section 241.
[0112] The ultrasonic transmitter 9 is mounted on the second pipe section 242.
[0113] like Figure 6 As shown, the ultrasonic transmitter 9 in this embodiment is spiral-shaped; the ultrasonic transmitter 9 is sleeved on the outer surface of the second pipe section 242.
[0114] In this embodiment, the ultrasonic transmitter is spiral-shaped. Therefore, the ultrasonic transmitter in this embodiment can emit ultrasonic waves at different heights and angles on the outer surface of the second tube segment 242 on which the ultrasonic transmitter is mounted (360-degree ultrasonic emission without dead angles), and the range of the emitted ultrasonic waves is wider.
[0115] In this embodiment, the limit switch triggering unit 10 is a pressure sensor or a limit switch.
[0116] In a specific application of this embodiment, the circuit board 3 is also provided with a circuit board 3 switch button and a power indicator light; in this embodiment, the power indicator light can display the battery power, charging power, and charging status inside the pen.
[0117] A second groove is also provided between the first groove 22 and the second mounting part 23 of the inner liner 2.
[0118] When the circuit board 3 is connected to the inner liner 2, the circuit board 3 switch button and power indicator on the circuit board 3 correspond to the second groove.
[0119] See Figure 2 The inner liner 2 also includes a charging port fixing part 26 disposed on the left side of the first mounting part 21.
[0120] A charging port is provided on the charging port fixing part 26.
[0121] The charging port is connected to the battery 5 in the first mounting part 21.
[0122] Specifically, the charging port in this embodiment is a TYPEC charging port.
[0123] The smart writing pen provided in this embodiment also includes:
[0124] Pen end cap. The pen end cap is provided with a charging hole. The pen end cap is fastened to the end of the pen barrel 1, and after the pen end cap is fastened to the end of the pen barrel 1, the charging port protrudes from the charging hole; in this embodiment, the charging hole is a TYPEC charging hole.
[0125] The pen barrel 1 has a triangular prism structure.
[0126] The outer surface of the pen barrel 1 is also provided with a first positioning groove, a second positioning groove, and a third positioning groove. In this embodiment, the positions of the first positioning groove, the second positioning groove, and the third positioning groove correspond to the positions of the thumb, index finger, and middle finger when holding the pen correctly, which facilitates the correction or standardization of pen-holding posture and ensures a comfortable pen grip.
[0127] Specifically, the smart writing pen also includes: a pen cap 11; as shown in the image. Figure 7As shown, a pen refill insertion / removal hole 111 is also provided on one side of the pen cap 11.
[0128] The pen refill insertion hole 111 includes a first end and a second end. The width of the pen refill insertion hole gradually decreases as it extends from the first end to the second end. In practical applications, the width of the first end of the pen refill insertion hole 111 is greater than the diameter of the pen refill 4, and the width of the second end of the pen refill insertion hole 111 is less than the diameter of the pen refill 4. Therefore, in this embodiment, after the smart writing pen is no longer in use, the pen refill protruding from the head of the pen can be inserted into the first end of the pen refill insertion hole 111, and then the pen refill can be moved along the direction of the second end of the pen refill insertion hole 111 until the pen refill insertion hole 111 engages the pen refill. At this point, the pen refill can be pulled out for easy replacement.
[0129] In this embodiment, the pen lead can be one of the following: pencil lead, water-based pen lead, gel pen lead, or chalk lead; no specific limitation is made in this regard.
[0130] The intelligent writing pen proposed in this embodiment employs an inner liner assembly and a pen barrel for accommodating the inner liner assembly. In this embodiment, the inner liner assembly is placed within the pen barrel. The inner liner assembly includes an inner liner, a circuit board, and a pen refill. The inner liner, from left to right, includes a first mounting portion, a first groove, a second mounting portion, and a third mounting portion. The first mounting portion houses a battery. The second mounting portion has a pen refill fixing member movable in the left-right direction. The third mounting portion has an infrared emitter and an ultrasonic emitter respectively connected to the circuit board. The circuit board covers the battery and the pen refill fixing member and is connected to the inner liner. The battery is connected to the circuit board. A limit switch triggering unit is provided on the circuit board. The limit switch triggering unit corresponds to the first groove, and the left end of the pen refill fixing member abuts against the limit switch triggering unit. The pen refill passes through the third mounting portion and is inserted from right to left into the pen refill insertion hole on the pen refill fixing member. When the intelligent writing pen in this embodiment is in use, the tip of the pen refill contacts the limit switch triggering unit, and the circuit board starts working after the pen refill fixing member applies pressure. Therefore, the smart writing pen in this embodiment does not have two parts, a pen tip and a pen body. Instead, it is formed into an integral structure by an inner liner component, which is then placed in the pen barrel. This ensures that the axis of the smart writing pen will not be skewed, thus improving the user experience.
[0131] On the other hand, this embodiment also provides an intelligent writing system, such as Figure 8 As shown, the intelligent writing system includes:
[0132] The data acquisition device 12 and the smart writing pen as described in the embodiment.
[0133] The acquisition device 12 includes a processor 124, a first ultrasonic receiver 121, a second ultrasonic receiver 123, and an infrared receiver 122.
[0134] The infrared receiver 122 is located between the first ultrasonic receiver 121 and the second ultrasonic receiver 123.
[0135] The processor 124 is connected to the first ultrasonic receiver 121, the second ultrasonic receiver 123, and the infrared receiver 122, respectively.
