Touch control pen structure and trigger module

Technical Field

The present disclosure relates to a stylus structure and a trigger module, and more particularly, to a stylus structure and a trigger module with a pre-touch structure design to improve the lifespan.

Background

In recent years, due to the rapid development of touch related technologies, the display screen of an electronic product is gradually changed from a conventional non-touch screen to a touch screen, and therefore, people can directly operate the electronic product on the touch screen without using a keyboard or a mouse. In order to improve the convenience of the user, most touch screens can be operated by a stylus, such as clicking, inputting information, or performing input actions such as drawing on a touch panel.

When a user operates an electronic product through a touch pen, the pen tip of the touch pen touches and presses a touch screen, so that the pen tip feeds back to touch and press a sensing element inside the touch pen, and further a touch signal is generated, and the electronic product can generate corresponding operation according to the touch signal. However, since the sensing element is a relatively fragile electronic element and is not in the way of the current stylus design, when the tip of the stylus is impacted, for example, the stylus falls to the ground, the tip touches the ground first; at this time, the feedback force generated by the pen tip may damage the sensing element, thereby causing damage to the stylus.

As shown in the drawings, the embodiment of the present application provides a stylus structure Z, which includes a writing module 1 and a triggering module D. The writing module 1 includes a pen housing unit 10, a touch unit 11, and a processing unit 12.

First, as shown in fig. 1 to fig. 3, the pen casing unit 10 may have a fixing portion 100, an accommodating space 101 and a through hole 102, wherein the fixing portion 100 is located in the accommodating space 101. For example, the pen body unit 10 may include a housing member 103, an upper cover member 104, and a lower cover member 105. The housing element 103 may be a tubular structure, one end of the housing element 103 has a through hole 102, and the inside of the housing element 103 may receive an upper cover element 104 and a lower cover element 105. The upper cover element 104 and the lower cover element 105 are detachably combined with each other, an accommodating space 101 can be defined between the upper cover element 104 and the lower cover element 105, and the accommodating space 101 can be used for accommodating the touch unit 11, the processing unit 12 and the trigger module D (to be described below). One surface of the lower cover element 105 corresponding to the accommodating space 101 may have a fixing portion 100.

Next, as shown in fig. 1 to 3 and 5, the touch unit 11 can be inserted into the through hole 102. For example, the touch unit 11 may include a pen core element 110 and a pen cap element 111, one end of the pen core element 110 may be used to contact an external electronic device E (for example, but not limited to, a smart phone, a touch display, a tablet computer, etc.), and the other end of the pen core element 110 may be detachably connected to one end of the pen cap element 111. The other end of the pen cap element 111 may have at least one abutting surface 1110 and a recess 1111, and the recess 1111 is connected to the at least one abutting surface 1110 and is used for accommodating the fixing portion 100; in this embodiment, two abutting surfaces 1110 are taken as examples, but not limited thereto. In addition, the top surface 1110 may be U-shaped or semicircular, but not limited thereto.

In addition, as shown in fig. 1 to fig. 3, the processing unit 12 is located in the accommodating space 101, and the processing unit 12 may be a circuit board with a processor, but not limited thereto.

Next, as shown in fig. 2 to 6 and 9, the triggering module D may include a fixing unit D1, a detecting unit D2 and an elastic unit D3.

As shown in fig. 2 to 4, fig. 6 and fig. 9, the fixing unit D1 is located in the accommodating space 101, and the fixing unit D1 has an opening D10 and an accommodating cavity D11. For example, the fixing unit D1 may be located between the touch unit 11 and the processing unit 12. The fixing unit D1 may be a housing structure and has a receiving cavity D11 and an opening D10 communicating with the receiving cavity D11. The accommodating cavity D11 can be used for accommodating the elastic unit D3. In addition, both sides of the fixing unit D1 may protrude outward to form engaging portions D12, and the lower cover element 105 may have a plurality of recesses 1050 corresponding to the engaging portions D12. The fixing unit D1 is detachably engaged with the corresponding recess 1050 by each engaging portion D12 to be fixed to the lower cover member 105.

In addition, as shown in fig. 2 to 4, 6 and 9, the detecting unit D2 is disposed in the opening D10, and the detecting unit D2 is electrically connected to the processing unit 12. For example, the detecting unit D2 may include a movable element D20 and a sensing element D21. The movable element D20 is movably disposed in the opening D10. The sensing element D21 is arranged at one end of the movable element D20 and is electrically connected with the processing unit 12; the detecting unit D2 can be electrically connected to the processing unit 12 through a connecting wire (not shown), such as a flexible cable, but not limited thereto), and the detecting unit D2 can be a pressure detector, but not limited thereto. Further, two sides of the movable element D20 may respectively protrude outward to form engaging portions D200, two sides of the fixed unit D1 may respectively be hollowed to form engaging portions D13 communicating with the accommodating cavity D11, and the movable element D20 may be movably connected to the corresponding engaging portion D13 through each engaging portion D200 to connect with the fixed unit D1. Moreover, one end of the movable element D20 may have a groove D202, the sensing element D21 is detachably disposed in the groove D202, one side of the sensing element D21 facing away from the movable element D20 has a detecting surface D210, one end of the movable element D20 has a pressure receiving surface D201 surrounding the detecting surface D210, and at least one abutting surface 1110 of the pen cap element 111 corresponds to the pressure receiving surface D201.

Next, as shown in fig. 2 to 4, 6 and 9, the elastic unit D3 is located in the accommodating cavity D11, and the elastic unit D3 abuts against the fixing unit D1 and the detecting unit D2. For example, one end of the elastic unit D3 abuts against the inner wall of the fixed unit D1, and one end of the elastic unit D3 abuts against the other end of the movable element D20. The elastic unit D3 may be a spring, but not limited thereto.

Therefore, the detecting unit D2 is pushed by the elastic unit D3 to contact the fixing portion 100 and obtain the first contact pressure. For example, as shown in fig. 2 to 4, 6, 7, 9 and 10, when the stylus pen structure Z is not in use, the elastic unit 13 pushes the movable element D20 by its own stretching force, so that the movable element D20 drives the sensing element D21 to contact the fixing portion 100, and the sensing element D21 obtains a first contact pressure. Then, the detecting unit D2 generates a first pressure signal according to the first contact pressure. Next, the processing unit 12 can determine that the stylus structure Z is currently in an unused state according to the first pressure signal, and therefore, the processing unit 12 is in an inactive state or in a state of not sending any touch signal to the outside; that is, the processor of the processing unit 12 is in an inactive state or in a state of not sending any touch signal to the outside.

On the contrary, when the touch unit 11 is pushed by the external force to push against the detecting unit D2, the detecting unit D2 pushes against the elastic unit D3 and contacts the fixing portion 100, and obtains the second contact pressure. Wherein the first contact pressure is greater than the second contact pressure. For example, as shown in fig. 2 to 4, fig. 6, fig. 8, fig. 9, and fig. 11, when the user operates the stylus structure Z of the present application, when the stylus structure Z is actuated by the user to touch the touch screen E1 of an external electronic device E (such as a smart phone, a touch display, a tablet computer, etc., but not limited thereto) with the pen tip of the pen core element 110, the pen core element 110 generates a feedback force to drive the pen sleeve element 111 toward the processing unit 12. Then, the pen cap element 111 pushes against the pressure-receiving surface D201 of the movable element D20 through the plurality of pushing surfaces 1110, so that the movable element D20 pushes against and compresses the elastic unit 13; at this time, since the movable element D20 drives the detecting unit D2 to move away from the fixing portion 100, the pressure applied to the detecting surface D210 becomes smaller, that is, the fixing portion 100 still touches the detecting surface D210, and generates the second contact pressure on the detecting surface D210, but the second contact pressure is smaller than the first contact pressure. Next, the detecting unit D2 may generate a second pressure signal according to the second contact pressure, and the processing unit 12 may generate a touch signal according to the second pressure signal. Then, at least one external electronic device E communicatively connected to the stylus structure Z may receive the touch signal and perform corresponding processing according to the touch signal, for example, the touch signal includes data of writing a digital "1", and the external electronic device E may display the digital "1" through the touch screen E1.

The processing unit 12 may include a communication element (not shown), such as a bluetooth communication element, and the processing unit 12 is communicatively connected to the external electronic device E through the communication element. In addition, as shown in fig. 10 and 11, the fixing portion 100 may further include a contact 1051, the contact 1051 may be a block structure made of metal, and the contact 1051 may be contacted with the detecting surface D210 of the detecting unit D2.

Therefore, according to the above-mentioned technical solution, the pre-pressed stylus pen structure Z is provided, and when the stylus pen structure Z is not used, the detecting unit D2 is pushed by the elastic unit D3 to contact the fixing portion 100, so as to obtain a contact pressure. Moreover, when the pen core element 110 of the stylus structure Z is accidentally bumped or knocked, the strong feedback force instantaneously generated by the pen core element 110 is indirectly transmitted to the elastic unit 13 and absorbed by the elastic unit 13, and the strong feedback force is not directly or indirectly transmitted to the detection surface D210 of the detection unit D2, so as to avoid or reduce the chance of damage to the detection unit D2, and improve the service lives of the detection unit D2 and the stylus structure Z.

It is noted that the detecting unit D2 of the present application is arranged in a reverse manner, different from the conventional stylus pen, so that the stylus pen structure Z of the present application can provide another feedback manner. For example, when the user operates the external electronic device E through the stylus structure Z, and the user uses the stylus structure Z to write on the touch screen E1 in a light touch manner, because the user only applies a small force, the detecting surface D210 and the fixing portion 100 are separated from each other and a fine distance is generated, and a contact pressure (first writing pressure for short) of the detecting surface D210 contacting the fixing portion 100 is smaller than the first contact pressure, the stylus structure Z writes a line with a smaller diameter (first line for short) on the touch screen E1; when the user makes a heavy force to press the touch screen E1 by the stylus structure Z, the distance between the detecting surface D210 and the fixing portion 100 is elongated, and the contact pressure of the detecting surface D210 contacting the fixing portion 100 is smaller than the first writing pressure, so that the line diameter of the line written on the touch screen E1 by the stylus structure Z is thicker than that of the first line. In other words, the thickness of the lines written on the touch screen E1 by the stylus structure Z can be changed according to the contact pressure between the fixing portion 100 and the detecting surface D210, and when the contact pressure between the fixing portion 100 and the detecting surface D210 is gradually decreased from large to small, the thickness of the lines written by the stylus structure Z is gradually increased from thin to thick; conversely, when the contact pressure of the detecting surface D210 contacting the fixing portion 100 is gradually increased from small to large, the thickness of the line written by the stylus structure Z is gradually decreased from thick to thin.

In addition, the processing unit 12 may have a pressure comparison table built therein, and the processing unit 12 generates a corresponding touch signal according to the received pressure signal and by comparing with the pressure comparison table. That is to say, the contact pressure generated by the contact between the fixing portion 100 and the detecting surface D210 is not limited to the content of the above embodiments, and in the process of operating the electronic product by the user using the stylus pen structure Z, the triggering module D can generate different or same contact pressures when the detecting surface D210 contacts the fixing portion 100 according to the force applied by the user, and the detecting unit D2 can also generate a plurality of same, partially same or different pressure signals correspondingly; correspondingly, the processing unit 12 can also generate a plurality of identical, partially identical or different pressure signals.

According to the above, the present application further provides a trigger module D, which is suitable for a stylus pen structure Z, wherein the stylus pen structure Z includes a pen case unit 10, a touch unit 11 and a processing unit 12, and the trigger module D includes a fixing unit D1, a detecting unit D2 and an elastic unit D3. The fixing unit D1 is located in the accommodating space 101 of the pen casing unit 10, and the fixing unit D1 has an opening D10 and an accommodating cavity D11. The detecting unit D2 is disposed in the opening D10, and the detecting unit D2 is electrically connected to the processing unit 12. The elastic unit D3 is located in the accommodating cavity D11, and the elastic unit D3 abuts against the fixing unit D1 and the detecting unit D2. The detecting unit D2 is pushed by the elastic unit D3 to contact the fixing portion 100 of the pen case unit 10 and obtain a first contact pressure. When the detecting unit D2 is pushed by the touch unit 11, the detecting unit D2 pushes the elastic unit D3 and contacts the fixing portion 100, and a second contact pressure is obtained. Wherein the first contact pressure is greater than the second contact pressure.

However, the above-mentioned example is only one possible embodiment and is not intended to limit the present application.
