Description

  The present invention relates to a disc stylus pen, and in particular, is a reinforced pen tip of a disc stylus pen that operates a touch pen and a capacitive touch sensor.

  An existing touch pen is generally an input device, and is an input device that performs various types of functions by touching or approaching the touch sensor surface of a touch sensor, such as a tablet terminal, a mobile terminal, a graphic terminal, and other suitable devices. is there. When an object touches or approaches the surface of a touch sensor, particularly a capacitive touch sensor, the capacitance changes in the touch panel where the capacitive coupling action is formed after touching or approaching. After the touch sensor controller, the capacitance change can be processed, the object is determined at the coordinates on the touch panel, the azimuth (eg azimuth angle and tilt angle) is calculated, and the example is written, drawn, painted Or it becomes easy to execute the selected operation by tapping with a touch pen on the panel.

  Several touch pen technologies with coordinate determination and azimuth calculation have already been developed. Some techniques search for capacitance by having one or more positions on the touch pen relative to the surface of the touch sensor. Then, the coordinates are determined using the capacitance, and the orientation of the touch pen facing the surface is calculated. Other technologies install a conductive board at the tip of the touch pen to ensure capacitive coupling between the touch pen and touch sensor touch panel surface.

  As for a touch pen including a conductive board, in some technologies, a pivoting connector, for example, a spherical column, is used by installing the touch pen on the conductive board. For this reason, when the user uses the touch pen, the conductive board keeps flat with the touch panel surface of the touch sensor.

JP 2016-197372 A

  The problem to be solved is that when the touch pen is used, the conductive board is unexpectedly detached from the spherical column when the rotation angle of the spherical column is maximized. In such a situation, the tensile force of the spherical column decreases. The tensile force there refers to the force that accepts the force that the spherical column tries to separate from the conductive board in the axial / radial upward direction. Therefore, after that, unexpected dropping frequently occurs. In addition, since the size of the conductive board is small and it is easy to clearly show the end points of the conductive board used by the user, the conductive board becomes invisible when it is removed unexpectedly. Therefore, the cost of the user increases when the conductive board is replaced.

  As shown in these figures, the reinforced pen tip of the disk stylus pen has the above-mentioned problems.

  The present invention includes a reinforcing ring, a flat plate, a spherical column, and a touch layer set. The reinforcing ring includes a ring body, a ring upper edge, a ring lower edge corresponding to the ring upper edge, and a ring edge extending inwardly from the ring upper edge. The flat plate includes a flat plate upper surface, a flat plate lower surface, and a conical storage portion extending upward from the center of the flat plate upper surface. The conical storage section includes a storage path. The spherical pillar includes a spherical head and a column body, and the spherical head is rotationally moved and placed in the storage path. The column body portion is electrically connected to a touch pen extending upward through the cone-shaped storage portion. The touch layer set is installed on the lower surface of the flat plate, and the touch layer set is electrically connected to the spherical head. While the spherical head rotates, the touch layer set, the cone-shaped storage portion and the inner edge of the annular body are characterized by keeping the spherical head in the storage passage.

  The reinforced pen tip of the disc stylus pen of the present invention has an advantage that it is difficult to come off even when the rotation angle of the spherical column is maximized.

  A main object of the present invention is to provide a reinforced pen tip of a disc stylus pen that can easily operate various touch pens and various capacitive touch sensors.

  To achieve the above object, the present invention provides an enhanced nib for a disk stylus pen. For use with a touch pen, the reinforced pen tip of the disc stylus pen includes a reinforced ring, a flat plate, a spherical column, and a touch layer set. The reinforcing ring includes a ring main body, an upper ring edge connected to the ring main body, a lower ring edge corresponding to the upper ring edge, and an inner ring edge extending inward from the upper ring edge. The flat plate includes a flat plate upper surface, a flat plate lower surface corresponding to the flat plate upper surface, and a conical storage portion extending upward from the center of the flat plate upper surface. Among them, the conical storage section includes a storage passage having a circular cross section. The spherical pillar includes a spherical head and a column body portion connected to the spherical head, and the spherical head is rotationally moved and placed in a storage passage. The column body portion extends upward through the conical storage portion and is electrically connected to the touch pen. The touch layer set is installed on the lower surface of the flat plate, and the touch layer set is electrically connected to the spherical head. While the spherical head is rotationally moved, the touch layer set, the cone-shaped storage part, and the peripheral edge of the spherical head keep the spherical head in the storage path.

  The present invention further has the following effects. The reinforced ring prevents the flat plate from being accidentally detached while the spherical column is in use. In addition, when the flat plate is injection-molded, the reinforcing ring is provided with an inner ring supporting convex edge and an outer ring supporting convex edge having high bonding strength and an annular tank integrally formed with the flat plate. They increase the tensile force of the spherical column, i.e. the tensile force refers to the receiving force before the spherical column separates its spherical head from the flat plate in the axial / radially upward direction.

  By touching the touch pen and moving along the touch sensor surface of the touch sensor, the flat board makes the user more natural and more precise by judging the clear visibility of the end points and accurate coordinates. (For example, clear visual field (no shielding point), sensitive end point identification, no delay, no wave line, etc.). Therefore, the experience of using the touch pen increases. The reinforced pen tip of the disk stylus pen of this embodiment increases the sensitivity of the touch pen when writing a thin line, further increases the service life due to the reinforced ring, and the tensile force gradually increases between the spherical column and the flat plate. To prevent it. The tensile force indicates that the force is applied for a long time and / or acts on the flat plate in the axial / radial direction. In addition, the replacement cost is low, the use of the maximum rotation angle is reliable and is prevented from coming off, and furthermore, the end point achieves clear visibility and accurate coordinate determination.

The pen tip 71 is composed of a reinforced pen tip 1 of a disk stylus pen that touches the touch operation surface of the capacitive touch sensor. The strengthening nib 1 of the disk stylus pen of this embodiment is the same center as the shape of the pen shell 72. However, in other different embodiments, the stylus tip 1 of the disc stylus pen need not be concentric with the pen shell 72, but is modified and not limited as required. The pen shell 72 may include a touch operation circuit, for example, a sensor component, a signal processing component, and other compatible components (the processing system circuit 73 and the power source 74 shown in FIG. 1). To do.

  In addition, the size of the reinforced pen tip 1 of the disk stylus pen of this embodiment is smaller than the size of the pen shell 72. However, in other different embodiments, the size of the strengthening nib 1 of the disc stylus pen may be the same or larger than the size of the pen shell 72 and is not limited. The stylus pen 1 of the disc stylus pen may be made of any suitable conductive material or non-conductive material, and is electrically connected from the reinforced pen tip 1 of the entire disc stylus pen to the pen tip portion 71 of the touch pen 7 and the pen shell 72.

To change.

  As shown in FIG. 2, the reinforced pen tip 1 of the disc stylus pen includes a reinforced ring 2, a flat plate 3, a spherical column 4, and a touch layer set 5. Since the flat plate 3 is used for a long time and / or acts by the axial / radial force of the reinforced pen tip 1 of the disk stylus pen, the tensile force between the spherical column 4 and the flat plate 3 is increased, The design and configuration of the board 3 prevents the spherical column 4 from loosening unexpectedly.

  3A, 3B, and 5A, the reinforcing ring 2 includes a ring main body 21, an upper ring edge 22 connected to the ring main body 21, a one-piece lower edge 23 corresponding to the upper ring edge 22, and a ring body. An inner ring edge 24 extending inward from the upper edge 22, an inner ring supporting convex edge 25 extending inward from the lower ring edge 23, and an outer ring supporting convex edge 26 extending outward from the lower ring edge 23 are provided. In the embodiment shown in FIGS. 3A and 3B, the reinforcing ring 2 includes bicyclic support convex edges 25, 26, and the bicyclic support convex edges 25, 26 are installed corresponding to the annular body edge 24. The shapes of the bicyclic support convex edges 25 and 26 include those not limited to an annular shape, a corrugated shape, a saw shape, or other suitable shapes, and are installed on both sides of the annular lower edge 23 of the annular body 21. However, in other different embodiments, the inner ring support convex edge 25 and the outer ring support convex edge 26 can be installed between the ring upper edge 21 of the ring body 21 and the ring lower edge 23 of the ring body 21, and the reinforcing ring 2 and Between the annular tank 334 of the flat board 3, it has high joint strength, clear end point visibility, and strengthening ability.

  The reinforcing ring 2 is composed of a solid mass, but the present embodiment is not limited to this. The reinforcement ring 2 is composed of one or more solid masses or solid masses with holes, and is provided with high bond strength, clear end point visibility and strengthening ability between the reinforcement ring 2 and the annular tank 334 of the flat plate 3. Like that. The reinforcing ring 2 is made of any suitable conductive or non-conductive material, stainless steel being the better, and the flexible modulus of the compatible conductive or non-conductive material is greater than that of the flat plate 3. The high curvature coefficient of the reinforcing ring 2, specifically, the relatively high curvature coefficient of the annular edge 24 increases the bonding strength between the spherical column 4 and the flat plate 3, and prevents the spherical column 4 from being unexpectedly detached. .

  The flat plate 3 includes a flat plate upper surface 31, a flat plate lower surface 32 corresponding to the flat plate upper surface 31, and a conical storage portion 33 extending upward from the center of the flat plate upper surface 31. Among them, the conical storage portion 33 includes a storage passage 331 having a circular cross section. The flat plate 3 is composed of any suitable non-conductive material, such as transparent polycarbonate (PC), polymethyl methacrylate (PMMA), or other plastic materials as required in this embodiment. The good thing of the flat board 3 in a present Example is a polycarbonate. The conical storage portion 33 further includes an upper edge 332 of the storage cavity, a lower edge 333 of the storage cavity, and an annular tank 334 provided around the storage passage 331. The reinforcing ring 2 is integrally formed with the annular tank 334, and the inner edge 24 of the reinforcing ring 2 is exposed and flattened at the same height as the upper edge 332 of the storage cavity of the storage passage 331 having a circular cross section. Accordingly, the shape of the annular tank 334 and the arrangement thereof correspond to the shape of the reinforcing ring 2 up to the inner ring edge 24.

  In the embodiment shown in FIGS. 3A, 3B and 5A, the good one of the ring body 21 of the reinforcing ring 2 is perpendicular to the flat plate lower surface 32 of the flat plate 3. However, the ring body 21 of the reinforcing ring 2 in the embodiment shown in FIGS. 4A, 4B and 5B may form a depression angle θ with the flat plate lower surface 32 of the flat plate 3. Specifically, the center of rotation of the ring body 21 and the spherical head 41 of the spherical pillar 4 has a depression angle θ. The depression angle θ is smaller than 90 degrees, and the size of the annular lower edge 23 is made larger than the size of the annular upper edge 22. In addition, when the flat plate 3 is injection molded and solidified, the inner ring supporting convex edge 25 and the outer ring supporting convex edge 26 of the reinforcing ring 2 increase the bonding strength between the reinforcing ring 2 and the annular tank 334.

  As shown in FIGS. 6A and 6B, the spherical column 4 includes a spherical head 41 and a column body portion 42 that connects the spherical head 41. The spherical head 41 is rotated and inserted into the storage passage 331, and the spherical head 41 is rotated inside. The column body portion 42 extends upward through the conical storage portion 33 and is electrically connected to the touch pen 7. The spherical column 4 of this embodiment is composed of any suitable conductive material, such as stainless steel, copper, copper or other similar material, the best of which is stainless steel.

  The column body part 42 includes a neck part 421, a conical step 422, a cylindrical body 423, and a rod end 424. The size of the neck portion 421 is smaller than the size of the spherical head 41 and the conical step 422, and the rotational movement angle θ at which the columnar portion 42 rotates the center relative to the relative spherical head 41 is at least 100 degrees or 100 degrees. This is shown in FIG. The neck 421 shown in FIGS. 6A and 6B is manufactured by integral molding with the spherical head 41, and the conical step 422 and the cylindrical body 423 are manufactured by integral molding with the conical step 422 and the rod end 424. In the embodiment shown in FIG. 6A, the rod end 424 has a good cylindrical shape, which electrically connects the reinforcing pen tip 1 of the disk stylus pen and presses the touch pen 7. However, in the embodiment shown in FIG. 6B, a good rod end 424 is a screw pattern (not shown), and the stylus pen 1 of the disk stylus pen is electrically connected and fixed to the touch pen 7 with screws. Accordingly, the reinforced pen tip 1 of the disk stylus pen of this embodiment is replaced and installed with the touch pen 7.

  As shown in FIGS. 8 and 9, the touch layer set 5 is installed on the flat plate lower surface 32. The touch layer set 5 electrically connects the spherical head 41 of the spherical column 4. While the spherical head 41 rotates and moves, the inner edge 24 of the touch layer set 5, the conical storage portion 33 and the reinforcing ring 2 keep the spherical head 41 within the storage passage 331. In the embodiment shown in FIG. 9, the touch layer set 5 includes a compressed conductive piece 51, a conductive support piece 52, an adhesive layer 53 having a center hole 531, and a conductive near-end layer 54. The adhesive layer 53 adheres the conductive near-end layer 54 to the flat plate lower surface 32 and the conductive support piece. The thickness of the adhesive layer 53 and the size of the center hole 531 are designed so that the compressed conductive piece 51, the conductive support piece 52, the adhesive layer 53, and the conductive near-end layer 54 are electrically connected to the electric contact ball column 4.

  In addition, the flat plate lower surface 32 includes a central circular hole 321, and the conductive support piece 52 is installed and placed in the central circular hole 321. The conductive support piece 52 includes an annular bottom mass 521, and the annular bottom mass 521 contacts the exposed surface of the adhesive layer 53. Good ones of the compressed conductive pieces 51 are manufactured from a compressed conductive material, and the conductive material is, for example, copper, silver, or other suitable material based on the needs of this embodiment. While the spherical head 41 is rotationally moved in the storage passageway 331, all contact surface areas (not shown) between the compressed conductive piece 51 and the spherical head 41 are kept in contact with each other. Specifically, the compressibility of the compressed conductive piece 51 not only allows continuous contact between the spherical head 41 and the compressed conductive piece 51 during use, but also the compressed conductive piece 51 rotates and presses with the spherical column 4. While the mark is made, the maximum possible contact area is formed between the spherical head 41 and the compressed conductive piece 51.

  A conductive material that is hard relative to the compressed conductive piece 51 is used for the conductive support piece 52 and causes the conductive support piece 52 to counteract the power on the reinforced pen tip 1 of the disk stylus pen. The conductive near-end layer 54 is made of any suitable conductive material, for example, a transparent conductive film of indium oxide (ITO), a transparent conductive film of aluminum-doped zinc oxide (Al-doped ZnO; AZO), or other compatible material. A good example of the conductive near-end layer 54 of this embodiment is ITO. While the spherical column 4 rotates and moves within the conical storage portion 33 of the flat plate 3, the ring-shaped bottom lump 521 of the conductive support piece 52 increases the bonding area of the adhesive layer 53 and is stabilized to the conductive support piece 52. To increase strength and stability.

  While the spherical head 41 rotates, the touch layer set 5, the conical storage portion 33 of the flat plate 3, and the inner peripheral edge 24 of the reinforcing ring 2 pass the spherical head 41 of the spherical column 4 within the circular passage storage passage 331. The spherical pillar 4 is prevented from being unexpectedly detached from the flat plate 3.
