Description

Technical Field

[0001] The utility model relates to the technical field of teleprompters, in particular to a teleprompter pen. Background Art

[0002] A word processor is a text prompt tool used to assist in speeches, broadcasts or performances. It is an indispensable tool in important occasions such as news broadcasts, advertising photography, conference speeches, etc. It can help speakers express their ideas and views accurately and fluently.

[0003] Existing teleprompters generally have the problems of taking up a lot of space, being inconvenient to carry or being obvious. When a user needs to give a speech without a script, the existing teleprompters are not convenient to remind the user in a relatively hidden way. At the same time, it is impossible for the user to use the fragmented time when waiting for a bus, taking the subway, or attending a party to review and memorize the script. Utility Model Content

[0004] The utility model aims to solve the problems that the teleprompter in the prior art is inconvenient to carry and is inconvenient to remind the user in a relatively concealed manner when the user needs to give an impromptu speech, and proposes a teleprompter pen.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A prompting pen comprises a pen body, a pen head is installed at one end of the pen body, a pen cap for controlling the extension and retraction of the pen head is installed at the other end of the pen body, and a switch, a lithium battery module, a 3.3V voltage regulator module, a main control chip, a button adjustment module, a display screen, a USB serial port module and an ESP burning module are installed inside the pen body;

[0007] The pins on the main control chip are connected to the button adjustment module to realize the functions of scrolling up and down and confirming and returning the subtitles;

[0008] The pins on the main control chip are connected to the display screen to achieve communication and display content.

[0009] Preferably, the button adjustment module includes a down button, an up button and an OK button, the down button is used to flip the subtitles downward, the up button is used to flip the subtitles upward, single-clicking the OK button can open the Tang poem, and double-clicking the OK button can return to the previous level.

[0010] Preferably, the flip up button is located above the flip down button, and the confirm button is located between the flip down button and the flip up button.

[0011] Preferably, an anti-slip cover is pasted on the outer surface of the middle part of the pen body to increase the friction between the pen body and the palm.

[0012] Compared with the prior art, the utility model provides a word prompting pen, which has the following beneficial effects:

[0013] By setting the traditional teleprompter to the shape of an ordinary ballpoint pen, the technical solution can make it easier for users to carry, so that when the user is on public transportation such as subways and buses, it is convenient for the user to review, memorize and recite manuscripts. Moreover, when the user needs to give an impromptu speech, holding a pen in hand is more convenient for body expression, and at the same time, necessary prompts are given to the user to make the whole process smoother, more natural and appropriate, showing their good manners. Or when attending a meeting and needing to report work impromptu and elaborate on data, numerical indicators, etc., the user can be prompted more covertly to make the report content more accurate and show the user's strong knowledge reserve, memory ability or workplace literacy. By displaying the required manuscripts on the display screen and selecting the corresponding subtitles through the button adjustment module, the user can directly check the display screen to find the answer when he encounters words and sentences he can't remember, which is very convenient.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] Reference Figure 1-2 A prompting pen comprises a pen body 1, a pen head 2 is installed at one end of the pen body 1, a pen cap 3 for controlling the extension and retraction of the pen head 2 is installed at the other end of the pen body 1, and a switch 6, a lithium battery module, a 3.3V voltage regulator module, a main control chip, a button adjustment module, a display screen 7, a USB serial port module and an ESP burning module are installed inside the pen body 1.

[0020] The pins on the main control chip are connected to the button adjustment module to realize the up and down scrolling and pause functions of the subtitles.

[0021] The pins on the main control chip are connected to the display screen 7 to achieve communication and display content.

[0022] By setting switch 6, the product can be turned on and off. The model of the main control chip is ESP01F, which has multiple communication modes such as WiFi communication and serial communication, and has good performance and low energy consumption. The IO12, IO13, and IO5 pins on ESP01F are connected to the button adjustment module, and the IO16 and IO2 pins on ESP01F are connected to the SDA and SCL of the display screen 7. This product uses the TP4059 chip as a charging chip, has a charging switch and a charging interface to achieve no need to cut off the power and reuse, and has an LED light group to realize charging and discharging prompts, and has an RT9193-33GB chip as a 3.3V voltage regulator chip to ensure stable operation. This product provides a USB serial port to realize external communication burning, and the CH340K chip realizes USB to serial port conversion. The D+ and D- pins on the USB are converted on the CH340k and connected to RXD and TXD to realize serial port communication.

[0023] The button adjustment module includes a down button 4, an up button 5 and an OK button 8. The down button 4 is used to flip the subtitles downward, the up button 5 is used to flip the subtitles upward, single-clicking the OK button 8 can open the document, and double-clicking the OK button 8 can return to the previous level; by setting the button adjustment module, you can more conveniently select the document you want to view.

[0024] The up button 5 is located above the down button 4, and the confirmation button 8 is located between the down button 4 and the up button 5; such a design of the button positions can make it easier for users to distinguish the three buttons and reduce the probability of misoperation.

[0025] An anti-slip cover is pasted on the outer surface of the middle part of the pen body 1 to increase the friction between the pen body 1 and the palm. By increasing the friction between the pen body 1 and the palm, it is more convenient for the user to hold the pen body 1 tightly.
