[0036] An embodiment of the present invention provides a capacitive stylus 1 for writing on a capacitive screen. Figures 3 to 5 As shown, the capacitive stylus pen 1 includes a pressing structure 100 and a pen head structure 200, and the pen head structure 200 is mounted on the pressing structure 100 by bonding. The pressing structure 100 includes a pen housing 10, a pressing assembly 20 and a pen cap 30. The pen housing 10 is provided with a cavity 13, the pressing assembly 20 is located in the cavity 13, and can move to a first locking position and a second locking position along the axis direction. The pen cap 30 is connected to the pressing assembly 20, and the pen cap 30 is in an extended state when the pressing assembly 20 moves to the first locking position, and the pen cap 30 is in a contracted state when the pressing assembly 20 moves to the second locking position.

[0037] In general, the capacitive stylus pen 1 is Figures 1 to 3 As shown, the capacitive pen 1 is placed in the pen cavity, and the pen cap 30 is in a retracted state. When in use, the pen cap 30 is pressed to move the pressing assembly 20 from the second locking position to the first locking position along the axial direction, and the pen cap 30 pops out of the pen cavity and is in an extended state, which is convenient for extracting the capacitive pen 1 from the pen cavity; after use, the capacitive pen 1 is put back into the pen cavity, and the pen cap 30 is pressed to reset the pressing assembly 20 from the first locking position to the second locking position along the axial direction, and the pen cap 30 is in a retracted state and stored in the pen cavity.

[0038] In this embodiment, if Figures 5 to 8As shown, the inner wall of the cavity 13 is provided with a guide groove 131, and the pressing assembly 20 includes a push rod 21, a first tooth column 22, a second tooth column 23 and an elastic member 24. The first tooth column 22 is fixed to the push rod 21, and the second tooth column 23 is sleeved on the push rod 21 and abuts against the first tooth column 22, so that when the push rod 21 and the first tooth column 22 move, the second tooth column 23 can be driven to move, and the movement of the first tooth column 22 and the second tooth column 23 is limited by the guide groove 131, and the elastic member 24 is sleeved on the push rod 21.

[0039] Furthermore, in this embodiment, if Figures 5 to 8 As shown, the first tooth column 22 and the second tooth column 23 respectively include a guide protrusion 25 that cooperates with the guide groove 131, so that the first tooth column 22 and the second tooth column 23 move along the guide groove 131, and when the second tooth column 23 moves to the second locking position, the guide protrusion 25 of the second tooth column 23 disengages from the guide groove 131 and rotates, and is locked with the pen housing 10 through the guide groove 131.

[0040] Specifically, in this embodiment, the inner wall of the cavity 13 is provided with a plurality of stepped guide grooves 131, and the guide grooves 131 include a straight groove portion for the first tooth column 22 and the second tooth column 23 to move in a straight line and a tooth groove portion capable of meshing with the second tooth column 23. Initially, the first tooth column 22 and the second tooth column 23 are not fully meshed, and only the tooth tips are partially meshed. When the pen cap 30 is pressed by hand, the pressure is transmitted to the push rod 21 and the first tooth column 22, and the first tooth column 22 moves along the guide groove 131 and pushes the second tooth column 23 to move until the guide protrusion 25 of the second tooth column 23 slides out of the straight groove portion. Since the second tooth column 23 has a tendency to mesh with the first tooth column 22, the second tooth column 23 is rotated by a certain angle, so that the tooth tip of the second tooth column 23 is The capacitive pen 1 is stored in the pen cavity under the action of the elastic member 24, and the pen cap 30 is pressed by hand again, and the pressure is transmitted to the push rod 21 and the first tooth column 22, and the first tooth column 22 moves along the guide groove 131, and then the pressure is transmitted to the second tooth column 23, so that the second tooth column 23 is rotated again by a certain angle, so that the teeth of the second tooth column 23 are disengaged from the tooth groove part to unlock the second tooth column 23, and under the action of the elastic member 24, the capacitive pen 1 is ejected from the pen cavity.

[0041] It is worth mentioning that, in this embodiment, Figures 5 to 7As shown, the pressing assembly 20 includes two elastic members 24, one end of one of the elastic members 24 abuts against the first tooth column 22, and the other end abuts against the inner wall of the cavity 13, and one end of the other elastic member 24 abuts against the second tooth column 23, and the other end abuts against the other inner wall of the cavity 13. The structural arrangement of the two elastic members 24 makes the overall pressing feel of the capacitive pen 1 more comfortable, and by arranging the elastic member 24 between the first tooth column 22 and the pen housing 10, the pen cap 30 can be reduced from loosening, and the pen cap 30 can be prevented from automatically extending or contracting, further improving the feel, thereby improving the user's experience.

[0042] In this embodiment, the number of the guide protrusions 25 of the first tooth column 22 and the second tooth column 23 is 2-5. Specifically, in this embodiment, the number of the guide protrusions 25 of the first tooth column 22 and the second tooth column 23 can be 2 or 3. If the number of the guide protrusions 25 of the first tooth column 22 and the second tooth column 23 is 1, it cannot meet the pressing requirements. If the number of the guide protrusions 25 of the first tooth column 22 and the second tooth column 23 is more than 5, it is not convenient to produce and process the capacitive stylus 1 due to its small overall size.

[0043] In this embodiment, the teeth of the first tooth column 22 and the second tooth column 23 are all helical teeth, and the number of teeth of the first tooth column 22 and the second tooth column 23 is 2-7. Since the first tooth column 22 and the second tooth column 23 both use helical teeth, compared with straight teeth, the smoothness can be improved. When pressing the pen cap 30, it is easier to drive the second tooth column 23 to move and rotate, thereby ensuring the smooth progress of the pressing process of the capacitive stylus 1. In addition, in this embodiment, the number of teeth of the first tooth column 22 and the second tooth column 23 can be 4 or 6, which is not only convenient for production and processing, but also convenient for the smooth progress of the pressing process of the capacitive stylus 1.

[0044] In this embodiment, the push rod 21 is made of metal. Specifically, in this embodiment, the push rod 21 is made of stainless steel. By using stainless steel to manufacture the push rod 21, the concentricity of the push rod 21, the first tooth column 22 and the second tooth column 23 during movement can be improved, the smoothness can be improved, the service life of the capacitive stylus 1 can be increased, and the cost of using stainless steel is low. Of course, in other embodiments, the material of the push rod 21 is not limited to stainless steel.

[0045] In this embodiment, the engagement amount between the second tooth column 23 and the pen housing 10 is 0.25-0.5 mm. By limiting the engagement amount, the engagement degree between the second tooth column 23 and the pen housing 10 is ensured in the second locking position, so that the second tooth column 23 can achieve a better position through the guide groove 131, and effectively prevent the second tooth column 23 from rotating and rebounding in the reverse direction after being positioned.

[0046] In this embodiment, if Figures 3 to 6As shown, the pen case 10 includes a pen holder 11 and a pen body 12 connected to each other, one end of one elastic member 24 abuts against the first tooth column 22, and the other end abuts against the inner wall of the pen body 12, and one end of another elastic member 24 abuts against the second tooth column 23, and the other end abuts against the inner wall of the pen holder 11. Since the pen case 10 adopts a two-section structure of the pen holder 11 and the pen body 12, it is convenient to install the pressing assembly 20. During installation, it is only necessary to insert the pressing assembly 20 from one end of the pen holder 11 into the cavity 13, and one elastic member 24 abuts against the inner wall of the pen holder 11, and then the end face of the pen body 12 and the end face of the pen holder 11 are installed together by snapping, and the other elastic member 24 abuts against the inner wall of the pen body 12.

[0047] In this embodiment, if Figure 3 and Figure 5 As shown, the pen cap 30 has an enlarged end 31 that is easy to press, and when the pen cap 30 is in an extended state, a gap 32 is formed between the enlarged end 31 and the pen housing 10. In this way, when the pen cap 30 is pressed to drive the pressing assembly 20 to move, the hand feel is effectively improved.

[0048] The above descriptions are merely embodiments of the present invention and are not intended to limit the patent scope of the present invention. Any equivalent transformations made using the contents of the present invention's specification and drawings, or directly or indirectly applied in related technical fields, are also included in the patent protection scope of the present invention.
