It should be understood, however, that these implementation details are not to be interpreted as limiting the disclosure. That is, in some embodiments of the present disclosure, these implementation details are not necessary. In addition, some conventional structures and elements are shown in simplified schematic form in the drawings. The same reference numbers will be used throughout the drawings to refer to the same or like elements.

Fig. 1 is a perspective view of a stylus according to an embodiment of the invention. Fig. 2 is a partial perspective view of the stylus of fig. 1. Fig. 3 is a partially exploded view of the stylus of fig. 1. Referring to fig. 1 to fig. 3, a touch pen 100 of the present embodiment includes a pen body 110, a carrying structure 120, a core structure 130, and a control circuit board 140. The pen body 110 includes a pen barrel 112 and a cap 114. The supporting structure 120 is disposed in the pen body 110 and is shielded by the pen shaft 112 and the cap 114, and the supporting structure 120 supports the control circuit board 140 through the supporting portion 128. The core structure 130 is disposed on the supporting structure 120 and protrudes from the core cover 114 for performing touch control.

Fig. 4 is a partial component front view of the stylus of fig. 2. Fig. 5 is a partial cross-sectional view of the stylus of fig. 1. Referring to fig. 2 to fig. 5, the supporting structure 120 of the present embodiment has a ring-shaped positioning portion 122, and the ring-shaped positioning portion 122 has a shaft hole 122a. The section S (shown in fig. 5) of the refill 130 is inserted into the shaft hole 122a, and the annular positioning portion 122 completely covers the section S of the refill 130 along the circumferential direction of the shaft hole 122a. That is, the supporting structure 120 completely surrounds the writing core structure 130 through the annular positioning portion 122 thereof. Therefore, the supporting structure 120 can position the core structure 130 reliably to have a good concentricity. Therefore, other components do not need to be additionally arranged to cooperate with the bearing structure 120 to position the core structure 130, and the number of components of the stylus 100 can be reduced to reduce the assembly difficulty and improve the assembly precision.

Referring to fig. 2, fig. 3 and fig. 5, in detail, the core structure 130 of the present embodiment includes a core 132 and a sleeve 134, a first portion 1341 of the sleeve 134 is sleeved on one end of the core 132 and passes through the shaft hole 122a, and the other end of the core 132 protrudes out of the pen body 110 at the core cover 114. In addition, the stylus 100 further includes a sensing element 150 and a triggering element 160. The sensing element 150 is disposed in the pen body 110 and coupled to the control circuit board 140. The trigger element 160 is, for example, a rubber member, and is disposed on the second portion 1342 of the sleeve 134 of the refill structure 130 and faces the sensing element 150. The core structure 130 is adapted to move toward the pen body 110 under a force so that the triggering element 160 contacts the sensing element 150 to generate a touch signal. In the present embodiment, the sensing element 150 is, for example, a pressure sensor, but the invention is not limited thereto. In other embodiments, the sensing element 150 may be an optical sensor, a magnetic sensor, or other types of sensors.

Further, in this embodiment, the stylus 100 further includes an elastic element 170, the bearing structure 120 has a first stopping portion 124 and a second stopping portion 126 opposite to the first stopping portion 124, and a portion of the core structure 130 and the elastic element 170 are limited between the first stopping portion 124 and the second stopping portion 126, so as to provide an elastic force to act on the core structure 130 through the elastic element 170. Specifically, the sleeve 134 of the refill 130 has a flange 134a at the first portion 1341, and the flange 134a abuts against the second stopper 126. The elastic element 170 is, for example, a spring and is sleeved on the second portion 1342 of the sleeve 134 of the core structure 130, opposite ends of the spring respectively abut against the first stopper 124 and the first portion 1341 of the sleeve 134 of the core structure 130, so that the spring is limited between the first stopper 124 and the sleeve 134 of the core structure 130, and applies an elastic force to the first portion 1341 of the sleeve 134. With this configuration, when the core 132 of the core structure 130 is subjected to an external force (e.g., an external force F from left to right in fig. 5), the core structure 130 resists the elastic force of the elastic member 170 and moves into the pen body 110, so as to make the triggering element 160 contact the sensing element 150 as described above. Moreover, when the refill 132 is no longer subjected to an external force, the refill structure 130 can be reset by the elastic force of the elastic member 170.

In the present embodiment, the annular positioning portion 122, the first blocking portion 124, the second blocking portion 126 and the bearing portion 128 of the bearing structure 120 are integrally formed. That is, the stylus pen 100 of the embodiment completes the assembly requirements of positioning the core structure 130, limiting the elastic element 170, and supporting the control circuit board 140 through the single component of the supporting structure 120, and does not need to complete the assembly requirements by arranging a plurality of components, so that the number of components can be greatly reduced and the assembly precision can be improved. Therefore, the distance (e.g., 0.05-0.1 mm) between the triggering element 160 and the sensing element 150 can be accurately controlled to ensure a good touch sensing effect.

Fig. 6 is a bottom view of the stylus of fig. 2. Referring to fig. 6, the supporting structure 120 of the present embodiment has two

holes

120a and 120b, at least a portion of the elastic element 170 is exposed by the hole 120a in the radial direction of the stylus 100, and at least a portion of the triggering element 160 and at least a portion of the sensing element 150 are exposed by the hole 120b in the radial direction of the stylus 100. Therefore, in the assembling process, whether the positions of the elastic member 170, the triggering element 160 and the sensing element 150 are correct or not can be observed through the

broken holes

120a and 120b, so that the triggering element 160 and the sensing element 150 can be accurately assembled in place through the limit of the bearing structure 120. In other embodiments, the

holes

120a and 120b may be connected to form a single hole.

Fig. 7 shows the supporting structure of fig. 2 having a cover. Referring to fig. 5 and 7, in order to make the sleeve 134, the elastic element 170, the trigger element 160 and other components in fig. 2 more stably disposed in the pen body 110 (shown in fig. 1), the stylus 100 may further include a cover 180, wherein the cover 180 is coupled to the supporting structure 120 to cover a portion of the sleeve 134 of the core structure 130 and the elastic member 170 and a portion of the trigger element 160 on the sleeve 134. In other embodiments, the cover 180 may be omitted and the sleeve 134, the elastic element 170, the trigger element 160, etc. may be disposed and limited by the single component of the supporting structure 120.

In summary, in the touch pen of the present invention, the supporting structure completely surrounds the core structure through the annular positioning portion, so as to position the core structure reliably and make it have good concentricity. In addition, the annular positioning part, the first stopping part, the second stopping part and the bearing part are integrally formed, so that the assembly requirements of positioning of the pencil core structure, limiting of the elastic part, bearing of the control circuit board and the like are met through the single component of the bearing structure, the assembly requirements are not needed to be met in a mode of arranging a plurality of components, the number of components can be greatly reduced, and the assembly precision is improved. Therefore, the distance between the trigger element and the sensing element can be accurately controlled, so that a good touch sensing effect is ensured.
