Description

Stylus with indent buffer

The present application is related to stylus, and in particular, refers to a stylus with a retractable buffer function.

With regard to the stylus, in order to achieve conduction when touched and non-conductive when not touched, a pressure-sensitive module (pressure sensing module) is installed in the stylus. The pressure-sensitive module has pressure-sensitive elements to utilize the The pressure element senses the touch pressure from the stylus core.

However, the inner end of the stylus core is connected with a connecting piece. When touching, the stylus core is retracted together with the connecting piece and presses the pressure-sensitive element with the connecting piece, so that the pressure-sensitive element senses the pressure from the stylus. In this way, once the pressure is too high, such as when the stylus falls, the head of the stylus core will retract together with the connecting piece due to the impact, and shrink inward. It has been criticized for a long time that the connecting piece hits the pressure-sensitive element from time to time, thereby causing the failure or damage of the pressure-sensitive element.

Therefore, how to design the present application that can improve the above-mentioned deficiencies in the prior art is a major problem that the creator of the present application is eager to solve.

The purpose of the present application is to provide a stylus with a retraction buffer function.

The inner shell 1 of the pen barrel has an inner wall 14 , and the inner shell 1 of the pen barrel 1 is provided with a positioning portion 141 on the inner wall 14 . And there is also a combination part 13 at one end of the inner shell 1 of the pen (the component symbols are not marked, as shown in the figure, it refers to the end of the pen head).

As shown in FIG. 2 and FIG. 4 , the pressure-sensitive module 2 is disposed and positioned in the positioning portion 141 , in other words, the pressure-sensitive module 2 is located in the inner shell 1 of the pen barrel. Among them, the pressure sensing module 2 (pressure sensing module) has a pressure sensing element 21, and the pressure sensing element 21 is used for sensing the pressure generated when the user touches.

The main circuit board M is fixed in the inner shell 1 of the pen barrel as shown in FIG. 2 and FIG. 4 . The flexible circuit board F is connected between the pressure sensing module 2 and the main circuit board M as shown in FIG. 2 and FIG. 4 .

As shown in FIG. 3 , the stylus refill 3 is divided into an inner section 31 and an outer section (component symbols are not indicated), and the stylus refill 3 has an outer end 32 in the outer section.

As shown in FIG. 3 and FIGS. 4 to 6 , the pen tip 4 is disposed and covered on the outer end 32 of the stylus refill 3 .

As shown in FIG. 2 to FIG. 6 , the limiting assembly 6 has a hollow socket 61 and a combined portion 62 . The inner shell 1 of the pen barrel 1 is combined with the combined portion 62 of the limiting member 6 with the combined portion 13, so that the hollow socket 61 of the limiting member 6 and the inner shell 1 of the pen barrel 1, which are also hollow, communicate with each other. The aforementioned stylus refill 3 is inserted through the hollow hole 61 and the inner section 31 of the stylus refill 3 extends into the inner shell 1 of the pen holder.

It should be noted that the present application does not limit the combination of the combining part 13 and the combined part 62, which can be screwed or buckled. As shown in the figure, the combining part 13 is a convex body and has an external thread As for the combined part 62, it is a corresponding concave part and has an internal thread, so that the combined part 13 can be combined with the combined part 62 in a detachable manner.

As shown in FIG. 2 to FIG. 6 , the engaging component 5 has an engaging portion 51 and a buffer crimping portion 52 which are linearly connected to each other. The buffer crimping portion 52 includes a hollow guide rod 521 , a crimping head 522 and a buffer member 523 . The hollow guide rod 521 has a cavity 5211, and the hollow guide rod 521 has a supported portion 5212 in the cavity 5211 (see FIG. 6); the crimping head 522 is movably accommodated in the cavity 5211 and located in the cavity 5211 The buffer member 523 is movably accommodated in the cavity 5211 and supported between the crimping head 522 and the supported portion 5212 . In addition, the crimping head 522 may be connected to the buffer member 523, but this is not limited in the present application.

It should be noted that the buffer member 523 can be any object or structure with a buffer function, especially an object or structure with an elastic buffer function. In this embodiment, an elastic support member 5231 (such as a spring or an elastic buffer body, etc.) , the spring can be a compression spring) as an example to illustrate, the elastic support 5231 is elastically supported between the pressure head 522 and the supported portion 5212; and the elastic support 5231 has a certain elastic supporting force, and is not elastic under normal conditions It shrinks elastically only when the external force is too large.

As shown in FIG. 6 , the connecting member 5 is connected to the inner section 31 of the stylus core 3 with its connecting portion 51 in the inner shell 1 of the pen barrel, so that the inner section 31 extends into the inner shell 1 of the pen barrel, and the pressure joint 522 corresponds to the inner section 31 of the stylus core 3 It is crimped on the pressure sensitive element 21 . In this way, when the user uses the normal touch, since the touch force during normal touch use does not exceed the elastic support force of the buffer member 523, the buffer member 523 does not elastically contract and can be used normally by touch; However, when the touch force is too large, or the stylus pen falls and the pen tip 4 is impacted, the stylus refill 3 retracts with the connecting assembly 5 relative to the inner shell 1 of the pen barrel, because the impact force is greater than that of the buffer member 523 . Elastic support force, so the buffer member 523 will elastically contract to produce the required buffer effect, so that the crimping head 522 will not act on the pressure-sensing force with excessive retraction force (including the aforementioned touch force and impact force). element 21, thereby ensuring that the pressure-sensitive element 21 will not fail or be damaged due to the above reasons in this paragraph. In other words, the entire distance that the stylus refill 3 can retract in (referring to the distance between the pen tip 4 and the inner shell 1 of the pen barrel, see Figure 6), the retraction force (including the aforementioned touch force and impact force) is greater than the buffer When the elastic supporting force of the member 523 is used, this distance will be absorbed by the buffer member 523 and will not act on the pressure-sensitive element 21 . Wherein, the so-called retraction refers to that part of the length of the stylus refill 3 is retracted into the inner shell 1 of the pen barrel from the tip 4 toward the tail of the pen.

It should be noted that, as shown in FIG. 6 , the cavity 5211 can be a straight cylindrical cavity (this application is not limited to this), the supported portion 5212 and the pressure-sensitive element 21 are linearly opposite to each other, and the crimping head 522 and The buffer members 523 are all located between the supported portion 5212 and the pressure sensing element 21 and are located on the same straight line. Therefore, the crimping head 522 can be linearly guided by the cavity 5211 to linearly expand and contract relative to the hollow guide rod 521 to ensure that the buffering function of the buffer member 523 can operate normally.

As shown in FIG. 1 and FIG. 6 , the pen barrel shell 7 surrounds the pen barrel inner shell 1 , and the limiting component 6 is sleeved by one end of the pen barrel shell 7 .
