Detailed Description

Fig. 1 is a schematic diagram of a stylus according to an embodiment of the invention. Fig. 2 is a schematic partial cross-sectional view of the stylus of fig. 1. For clarity and convenience of illustration, fig. 1 shows the tube 111 and the second tube 130 of the pen barrel 110 in a perspective manner, and shows the inner contour of the second tube 130 in a dotted line. Referring to fig. 1 and fig. 2, in the present embodiment, the stylus 100 may be a capacitive stylus or a resistive stylus, which is not limited in the invention. The stylus 100 includes a barrel 110, a first barrel 120, a second barrel 130, a driving member 140, an actuating member 150, a first elastic member 160, and a second elastic member 170.

Specifically, the pen barrel 110 includes a tube 111 and a pen core 112, wherein the pen core 112 is inserted into the tube 111, and the tube 111 has two

opposite ends

113 and 114. The pen core 112 is partially exposed at the end 113 to serve as a touch portion for the touch pen 100 to touch the touch screen. The first pen tube 120 has a first end 121, a second end 122 opposite to the first end 121, and a first engaging groove 123 located at the second end 122, wherein the first end 121 is fixed to the end 114 of the pen shaft 110 in a penetrating manner, and the second pen tube 130 is sleeved on the second end 122 (or called, the second end 122 is fixed to the second pen tube 130 in a penetrating manner). The second barrel 130 maintains the degree of freedom of reciprocating movement relative to the barrel 110 and the first barrel 120 to abut against the end 114 or move away from the end 114, so that the overall length of the stylus 100 can be adjusted according to the personal requirements of the user to obtain a better operation feeling.

In this embodiment, the driving element 140 is disposed in the second end 122 of the first barrel 120, and opposite ends of the first elastic element 160 respectively abut against the barrel 110 and the driving element 140. In detail, the driving member 140 includes a main body 141, two elastic deformation portions 142, and two engaging portions 143, wherein fig. 2 exemplarily shows two elastic deformation portions 142, two engaging portions 143, and two first engaging slots 123. Only one set of the elastic deformation portion 142, the engaging portion 143, and the first engaging groove 123 will be described below by way of example.

Referring to fig. 1 and fig. 2, the elastic deformation portion 142 is connected to the main body 141, wherein the engaging portion 143 is protruded on an outer wall surface of the elastic deformation portion 142, and the engaging portion 143 is engaged with the first engaging groove 123. When the engaging portion 143 is engaged with the first engaging groove 123, one end of the second tube 130 abuts against the end 114 of the pen barrel 110 (at this time, the first tube 120 is completely hidden in the tube 111 and the second tube 130), and the overall length of the stylus 100 can be maintained at the initial length (i.e. the state shown in fig. 1), so as to be convenient for a user to carry or be accommodated in a reserved space in a corresponding electronic device. Further, the engaging portion 143 can be separated from the first engaging groove 123 by the elastic deformation generated by the elastic deformation portion 142, so that the driving member 140 can move freely in the first pen barrel 120, and the driving member 140 drives the actuating member 150 and the second pen barrel 130, so as to adjust the overall length of the stylus 100.

In detail, the first elastic member 160 is disposed in the first barrel 120, wherein the body 141 of the driving member 140 abuts one end of the first elastic member 160, and the other end of the first elastic member 160 abuts the pen core 112 of the pen barrel 110. At this time, the first elastic member 160 is in a compressed state, and when the engaging portion 143 is engaged with the first engaging groove 123, the driving member 140 cannot move relative to the first pen barrel 120, and thus the elastic potential energy accumulated in the first elastic member 160 cannot be released.

Specifically, the second barrel 130 further has a first space 131, a first through hole 132, a second space 133, and a second through hole 134, which are sequentially arranged in a direction away from the barrel 110. The first space 131 is configured to receive the second end 122 of the first barrel 120 and is in communication with the interior space of the first barrel 120. The first through hole 132 communicates the first space 131 with the second space 133, and the second through hole 134 communicates the second space 133 with the outside. The first through hole 132 and the second through hole 134 are respectively located at two opposite sides of the second space 133.

In this embodiment, the actuator 150 is disposed through the second barrel 130 and the first barrel 120, and is coupled to the driving member 140 by a portion located inside the first barrel 120. The first elastic member 160 and the actuating member 150 are respectively located at two opposite sides of the driving member 140. In detail, the actuating member 150 includes an actuating portion 151, a limiting portion 152 and a pressing portion 153, wherein the actuating portion 151 and the pressing portion 153 are respectively located at two opposite sides of the limiting portion 152, and the limiting portion 152 connects the actuating portion 151 and the pressing portion 153. The actuating portion 151 passes through the second space 133, the first through hole 132 and the first space 131, and penetrates the first pen barrel 120 to abut against the elastic deformation portion 142. In other words, the pressing portion 153 and the elastic deformation portion 142 are located on opposite sides of the actuating portion 151, respectively. The stopper 152 is disposed in the second space 133, and since the outer diameter of the stopper 152 is larger than the inner diameters of the first through hole 132 and the second through hole 134, the stopper 152 is restricted from reciprocating in the second space 133. The pressing portion 153 penetrates through the second through hole 134, and at least a portion of the pressing portion 153 is exposed out of the second through hole 134 for a user to press.

The second elastic member 170 is disposed in the first pen tube 120, and two opposite ends of the second elastic member 170 are respectively connected to the actuating member 150 and the driving member 140. In detail, the actuating member 150 further includes a first connecting portion 154 and a first positioning portion 155 located in the first barrel 120. As shown in fig. 2, the actuating portions 151 may be two in number and symmetrically disposed at opposite sides of the first connecting portion 154. Further, the first connecting portion 154 is used to connect the two actuating portions 151 symmetrically disposed, wherein the first positioning portion 155 is connected to the first connecting portion 154 and extends toward the driving member 140. It should be noted that fig. 2 exemplarily shows two actuating portions 151 that are symmetrically arranged, and only one of the actuating portions 151 is exemplified below.

On the other hand, the driving element 140 further includes a second connecting portion 144 and a second positioning portion 146, wherein the second connecting portion 144 connects the main body 141 and the second positioning portion 146, and the second connecting portion 144 and the second positioning portion 146 are located between the two elastic deformation portions 142 that are symmetrically disposed. The second connecting portion 144 and the second positioning portion 146 are aligned with the first positioning portion 155 and extend toward the first positioning portion 155. The second connecting portion 144 may have a relief space 145 configured to move into the elastic deformation portion 142 when the elastic deformation portion is pushed by the actuating portion 151 to generate elastic deformation.

As shown in fig. 2, the first positioning portion 155 and the second positioning portion 146 are aligned with each other, and two opposite ends of the second elastic member 170 are respectively sleeved on the first positioning portion 155 and the second positioning portion 146. In other words, the first positioning portion 155 and the second positioning portion 146 are respectively disposed through the two opposite ends of the second elastic member 170, and one end of the second elastic member 170, which is sleeved on the first positioning portion 155, abuts against the first connecting portion 154.

In this embodiment, the engaging portion 143 includes a first engaging portion 143a and a second engaging portion 143b, which are disposed in parallel, wherein the first engaging portion 143a is configured to fix a relative position between the driving member 140 and the first pen barrel 120, and the second engaging portion 143b is configured to fix a relative position between the second pen barrel 130 and the first pen barrel 120. Further, the second end 122 of the first barrel 120 further has a second engaging groove 124, and the first engaging groove 123 is located between the barrel 110 and the second engaging groove 124 (or, the first engaging groove 123 is located between the first end 121 and the second engaging groove 124). In other words, a distance between the second card slot 124 and the barrel 110 is greater than a distance between the first card slot 123 and the barrel 110. On the other hand, the first pen barrel 120 further has a sliding slot 125, wherein the sliding slot 125 is configured to communicate the first engaging slot 123 and the second engaging slot 124 opposite to each other, and the second engaging portion 143b can reciprocate between the first engaging slot 123 and the second engaging slot 124 along the sliding slot 125. On the other hand, the second pen tube 130 further has a third engaging groove 135 for the second engaging portion 143b to penetrate therethrough. It should be noted that fig. 2 exemplarily shows two symmetrically disposed second card slots 124, two symmetrically disposed third card slots 135, and two symmetrically disposed sliding slots 125, and only one set of the second card slots 124, the third card slots 135, and the sliding slots 125 is illustrated below.

As shown in fig. 2, when the second pen tube 130 abuts against the pen holder 110, the third engaging groove 135 is aligned with the first engaging groove 123, wherein the first engaging portion 143a is engaged with the first engaging groove 123, and the second engaging portion 143b passes through the first engaging groove 123 and is engaged with the third engaging groove 135. In this state, the driving member 140 cannot move relative to the first barrel 120, and the second barrel 130 cannot move relative to the first barrel 120, so that the entire length of the stylus 100 can be maintained at the initial length (i.e., the state shown in fig. 1).

Fig. 3 is a schematic view of the actuator of the stylus pen of fig. 1 pressed by an external force. Fig. 4 is a schematic partial cross-sectional view of the stylus of fig. 3. Fig. 5 is a schematic diagram of the stylus pen of fig. 3 after the second pen barrel moves towards the second direction. Fig. 6 is a partial cross-sectional schematic view of the stylus of fig. 5. For clarity and convenience of illustration, fig. 3 and 5 show the tube 111 and the second tube 130 of the pen barrel 110 in a perspective manner, and show the inner contour of the second tube 130 in a dotted line.

Referring to fig. 3 and 4, when the second barrel 130 abuts against the barrel 110 and the entire length of the stylus 100 is maintained at the initial length, a user can apply a force to press the pressing portion 153 of the actuator 150, so that at least a portion of the pressing portion 153 moves into the second space 133, and the actuator 150 moves toward the first direction D1 (or toward the barrel 110). At this time, the elastic deformation portion 142 is pushed by the actuating portion 151 to generate elastic deformation, and the first engaging portion 143a is separated from the first engaging groove 123, so as to release the structural interference between the driving member 140 and the first pen barrel 120. Meanwhile, the second engaging portion 143b is also separated from the third engaging groove 135, so as to release the structural interference between the driving member 140 and the second pen barrel 130. During the elastic deformation of the elastic deformation portion 142, at least a portion of the elastic deformation portion 142 moves into the relief space 145, so that the first engaging portion 143a and the first engaging groove 123 can be smoothly separated, and the second engaging portion 143b and the third engaging groove 135 can be smoothly separated.

Referring to fig. 3 to 6, after the structural interference between the driving member 140 and the first barrel 120 is released and the structural interference between the driving member 140 and the second barrel 130 is released, the elastic potential energy accumulated by the first elastic member 160 is released to push the driving member 140 to move away from the barrel 110 relative to the first barrel 120 (or move relative to the first barrel 120 in a second direction D2 opposite to the first direction D1). Meanwhile, the actuator 150 and the second pen barrel 130 are driven by the driving member 140 to move in the second direction D2. During the movement of the driving member 140, the actuating member 150 and the second pen barrel 130 relative to the first pen barrel 120 in the second direction D2, the second engaging portion 143b moves into the sliding slot 125 from the first engaging groove 123, passes through the second engaging groove 124 after moving through the sliding slot 125, and engages with the third engaging groove 135 aligned with the second engaging groove 124. Meanwhile, the first engaging portion 143a moves from the position of the first card slot 123 to the position of the second card slot 124, and is further engaged with the second card slot 124.

Specifically, when the actuator 150 moves in the first direction D1 and the actuator 151 abuts against the first engaging portion 143a, the actuator 150 stops moving relative to the first barrel 120 and the second barrel 130. On the other hand, since the position-limiting portion 152 of the actuator 150 can only reciprocate in the second space 133, the moving stroke of the position-limiting portion 152 in the second space 133 can be used to determine the moving stroke of the actuator 150 relative to the second pen barrel 130.

As shown in fig. 3 and 4, when the actuating portion 151 abuts against the first engaging portion 143a, the second elastic element 170 is pushed by the first connecting portion 154 to be compressed and deformed, and is elastically deformed. On the contrary, when the external force applied to the pressing portion 153 is removed, the elastic potential energy accumulated by the second elastic member 170 in the compressed state is released to push the actuating member 150 to move toward the second direction D2 relative to the second pen barrel 130, so that the actuating portion 151 is separated from the first engaging portion 143a, and at least a portion of the pressing portion 153 is moved out of the second pen barrel 130 from the second through hole 134, as shown in fig. 5 and 6.

Further, after the structural interference between the driving release member 140 and the first barrel 120 is released and the structural interference between the driving release member 140 and the second barrel 130 is released, the barrel 110 and the first barrel 120 are fixed. After the external force applied to the pressing portion 153 is removed, the stopper portion 152 moves from the inner wall surface of the second space 133 connecting the first through hole 132 to the other inner wall surface of the second space 133 connecting the second through hole 134, and abuts against the other inner wall surface of the second space 133 connecting the second through hole 134. Thus, when the actuator 150 is pushed by the driving member 140 to move in the second direction D2, the second barrel 130 can be synchronously driven by the actuator 150 to move relative to the first barrel 120, so that the third engaging groove 135 moves away from the first engaging groove 123 (or moves toward the second engaging groove 124), until the first elastic member 160 returns to the initial length when it is not compressed and deformed, the actuator 150 stops moving relative to the first barrel 120, and the third engaging groove 135 is aligned with the second engaging groove 124. While the third engaging groove 135 is aligned with the second engaging groove 124, the second engaging portion 143b passes through the second engaging groove 124 and engages with the third engaging groove 135, so as to fix the relative position of the second pen barrel 130 and the first pen barrel 120. The first engaging portion 143a is engaged with the second engaging groove 124 to fix the relative position of the driving member 140 and the first pen barrel 120.

As shown in fig. 6, the stylus pen 100 can separate the second barrel 130 originally abutting against the pen barrel 110 by the relative movement of the second barrel 130 with respect to the pen barrel 110 and the first barrel 120, so as to extend the entire length of the stylus pen 100, and fix the stylus pen 100 in the state shown in fig. 6 by the structural interference between the driving member 140 and the second barrel 130 and the structural interference between the driving member 140 and the first barrel 120. At this time, a portion of the first barrel 120 is exposed between the barrel 110 and the second barrel 130. After the entire length of the stylus 100 is extended, it can provide a better operation feeling for the user. In contrast, the user can apply a force to press the pressing portion 153 in the first direction D1, and push the second barrel 130 to move in the first direction D1 relative to the first barrel 120, so as to return the stylus pen 100 to the state shown in fig. 1 and 2.

In summary, the touch pen of the present invention can release the structural interference between the driving member and the first barrel and the structural interference between the driving member and the second barrel by pressing and actuating, so that the actuating member can be pushed by the first elastic member to move relative to the first barrel and drive the second barrel to move relative to the first barrel, so as to extend the entire length of the touch pen. Correspondingly, the user can also return the entire length of the stylus to the original length by pressing and actuating. Therefore, the stylus of the present invention is more flexible in operation. In addition, the user can adjust the whole length of the touch pen according to personal requirements so as to obtain better operation hand feeling.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
