Description

Technical Field

[0001] The utility model relates to the technical field of dot matrix pens, in particular to an improved dot matrix pen. Background Art

[0002] The dot pen is a new type of digital drawing tool. It uses the internal camera, pressure sensor, motherboard and software algorithm to cooperate with each other to detect the writing position and pressure of the pen tip on the dotted paper book. When the user uses the dot pen to draw, these sensors will convert the coordinate position of the pen tip into a digital signal and then transmit it to the computer or other display device. On these devices, the corresponding image can be generated according to the received coordinate position and pressure information. The dot pen can adjust the drawing parameters such as thickness, color and transparency according to the user's drawing speed and pressure changes, so as to achieve a more realistic drawing effect. In addition, the dot pen can also transmit the handwriting data to the application via Bluetooth or Wi-Fi, and further develop various application software to meet different usage needs.

[0003] At present, the mainstream dot matrix pen on the market usually uses Hall induction to wake up the machine. The Hall switch is inside the pen and the magnet is inside the pen cap. The positions of the two correspond when the pen cap is buckled. When the pen cap is buckled, the Hall switch continuously senses the magnetic field, keeping the other systems of the entire pen in the off state; when the pen cap is opened, the Hall switch does not sense the magnetic field, activating the entire system of the pen and making it active; there is no problem with the principle of this structure, but during use, since the pen cap can be rotated after buckling, when the Hall switch is turned to face the back of the magnet, the sensitivity and accuracy of recognition will be slightly reduced. During use, when the pen cap is buckled and turned to face the back of the magnet, the sensitivity and accuracy of recognition will be slightly reduced. The existing structure and technology cannot improve the sensitivity and accuracy of recognition without affecting the user experience. And the realization of power on and off through Hall induction has requirements for the environmental magnetic field, which may be interfered by the external magnetic field. The pen may cause abnormal shutdown when writing close to magnetic objects. Utility Model Content

By arranging a pressure sensor detection device, the device can be operated or shut down to increase the service life of the device. The detection sensitivity is not affected by the magnetic field, and there is no need to add a magnet inside the pen cap, which greatly reduces the cost of the pen cap.

[0020] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0021] Reference Figures 1 to 5 The utility model embodiment is an improved dot matrix pen, which includes a pen assembly 1, the pen assembly 1 includes a pen body 12, and the pen body 12 is provided with an inner pen assembly 2, the inner pen assembly 2 includes a pen core 21, a soft pad 22 and a pressure-sensitive bracket 31, the soft pad 22 is located at the front end of the pen core 21, and the outer periphery of the pen core 21 is provided with a pen body bracket 23. The material of the soft pad 22 is silicone, which can be used for a long time in a high temperature environment, and will not deform, expand, or melt, and is not easily corroded by chemicals, acids, alkalis, salts and other substances. It can be used stably for a long time, has good comprehensive durability, and can maintain its mechanical strength and elasticity for a long time. The thickness of the soft pad 22 needs to match the minimum trigger amount of the pressure sense according to the applied force of the actual compression amount.

[0022] The pen assembly 1 includes a pen head 13, a pressure sensor 32 is arranged inside the pen head 13, a pressure sensor bracket 31 is sleeved on the periphery of the pen core 21, and the pressure sensor 32 is located above the pressure sensor bracket 31. The pressure sensor bracket 31 isolates the pen core 21 from direct contact with the pressure sensor 32, which not only provides a buffer protection effect, but also makes the force applied to the pressure sensor more uniform. When the pen cap 11 is pulled off, the pressure sensor 32 provides a detected power-on trigger factor, and the power-off state is entered only when the pressure sensor 32 is detected to be in the trigger state for a long time, so as to prevent the power-off from being mistakenly judged as shutting down due to writing cursive characters.

[0023] The pen assembly 1 comprises a pen cap 11, a pen head 13 sleeved on the top of a pen body 12, and the pen cap 11 sleeved on the bottom of the pen body 12. The pen cap 11, the pen body 12 and the pen head 13 are all outer shells, which play a role in protecting dust and moisture.

[0024] Working principle: The pen core 21 works through the pressure sensor 32. The sensing circuit enters the shutdown state only when it detects that the pressure sensor 32 is in the trigger state for a long time, preventing the system from being shut down by mistake due to writing cursive characters. This circuit is an OR gate. If it is high, the system is in the power-on state. The main control can make a judgment whether the pressure sensor is accidentally triggered by writing, and send a signal to prevent accidental shutdown.

[0025] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
