Description

[0001] The present invention relates to the technical field of capacitive pens, and in particular to a multi-pressure sensing recognition capacitive pen and a working method thereof. Background Art

[0002] A capacitive pen is a pen made of conductive material with conductive properties, used to touch the capacitive screen to complete human-computer dialogue operations. The capacitive pen is an auxiliary device that uses conductive material to imitate the human body to complete human-computer dialogue.

[0003] When using the existing capacitive stylus, it is necessary to hold the conductive part of the capacitive stylus to realize the writing function. Since the tip of the existing capacitive stylus has a certain length, and different people have different palm sizes and different writing strengths, when different people hold the capacitive stylus, the inclination angle of the capacitive stylus is different, which affects the comfort of use for different people.

[0004] In addition, the existing capacitive pen tips are divided into disc-type tips and pointed tips. When writing, the pointed tip is more comfortable than the disc-type tip, and vice versa. The existing capacitive pen tip style is fixed, and it is impossible to switch between the disc-type tip and the pointed tip. Therefore, a multi-pressure recognition capacitive pen and a working method thereof are proposed to solve the above problems. Summary of the invention

[0032] It should be noted that the upper conductive plate 3, the lower conductive plate 5, the conductive tube 4 and the sliding column 10 can make the current on the pen head assembly flow to the sensing sensor 22, thereby ensuring the normal writing function of the capacitive pen;

[0033] It is worth noting that the setting of the insulating spring 11 allows the conductive column 6 and the pen head assembly to be reset when the limiting assembly is separated from the limiting sheet 13;

[0034] A rolling groove is provided at the bottom end of the conductive column 6, a universal ball 17 is rollingly connected in the rolling groove, an adapter 15 is fixedly connected to the bottom end of the universal ball 17, a pen tip assembly is provided at the bottom end of the adapter 15, the pen tip assembly includes a magnetic ring 8 slidably connected to the surface of the adapter 15, a plurality of circumferentially distributed steering grooves are provided at the bottom end of the adapter 15, a combination head 9 is rotatably connected in the steering groove, the top end of the magnetic ring 8 and the bottom end of the threaded ring 7 are magnetically attracted to each other, a transmission rod 23 is rotatably connected between the side wall of the magnetic ring 8 and the side wall of the combination head 9, an elastic membrane 24 is commonly connected to the inner wall of the combination head 9, and a magnetic rubber patch is provided on the side wall of the combination head 9;

[0035] It should be noted that: under the action of the universal ball 17 and the rolling groove, the use angle of the disc-type pen head can be adjusted arbitrarily, thereby improving the flexibility of use;

[0036] It is worth noting that: the interior of the elastic membrane 24 is filled with a metal wire that runs through it, and the metal wire is fixedly connected to the assembly head 9;

[0037] It is worth noting that a groove is provided inside the combination head 9 to facilitate accommodating the elastic membrane 24 when the combination head 9 is closed.

[0038] The top of the magnetic ring 8 and the bottom of the threaded ring 7 are magnetically attracted to each other, which can achieve the stability of the combined head 9 after unfolding, and ensure the stability of the disc-type pen head when in use;

[0039] The limit assembly includes a pressing rod 16 slidably connected in the sliding hole, an auxiliary block 19 fixedly connected to one end of the pressing rod 16, a connecting rod 20 fixedly connected to one end of the auxiliary block 19, and a limit hook 21 fixedly connected to one end of the connecting rod 20, a return spring 18 is fixedly connected between the auxiliary block 19 and the inner wall of the induction sensor 22, and an annular protective film 2 is fixedly connected to the outer wall of the induction sensor 22;

[0040] It should be noted that: by pressing the pressing rod 16, the limit hook 21 is separated from the limit plate 13. Then, when the user uses the capacitive pen, the pen head assembly will move the conductive column 6 into the pen body 1 under the action of writing pressure, so that the use length of the pen head assembly can be adjusted. After releasing the pressing rod 16, under the action of the reset spring 18, the limit hook 21 is engaged with the limit plate 13 to realize the limit function of the moving shaft 14, and then realize the limit function of the pen head assembly, ensuring the stability of the use length of the pen head assembly after adjustment.

[0041] The surfaces of the conductive column 6 and the adapter 15 are both provided with external threads, and the surfaces of the conductive column 6 and the adapter 15 are both threadedly connected with a threaded ring 7;

[0042] It should be noted that the threaded ring 7 is used to realize the limiting function of the adapter 15 to ensure that the pen tip assembly is prevented from shaking when the pointed pen tip is used.

[0043] A working method of a multi-pressure sensing capacitive stylus comprises the following steps:

[0044] Step 1: Adjust the length of the pen tip assembly: The user holds the annular protective film 2 on the surface of the pen body 1, thereby keeping the pressing rod 16 pressed, so that the limit hook 21 is separated from the limit sheet 13, and keeps writing. When the pen tip assembly contacts the display screen, the conductive column 6 will shrink into the pen body 1 under the effect of the writing force. At this time, the length of the pen tip assembly is the appropriate length for the user, and then the pressing rod 16 is released, so that the length of the pen tip assembly can be adjusted according to the writing force of different people;

[0045] Step 2: Switch the disc-type pen head state: first, rotate the threaded ring 7 to separate the threaded ring 7 from the conductive column 6, then move the magnetic ring 8 upward, the magnetic ring 8 and the threaded ring 7 are magnetically attracted, and at the same time, under the action of the transmission rod 23, the combined head 9 is unfolded to a horizontal state, thereby propping up the elastic membrane 24, so that the elastic membrane 24 forms a disc state;

[0046] Step 3: Switch the state of the pointed pen tip: rotate the threaded ring 7 to make the threaded ring 7 and the conductive column 6 threadedly connected, and then make the unfolded combination heads 9 close to each other to form a pointed pen tip. Under the action of the magnetic rubber patch, the combination heads 9 can stably form a pointed pen tip.

[0047] When the present invention is used, the use length of the pen head assembly is adjusted by holding the annular protective film 2 on the surface of the pen body 1 by the user, thereby keeping the pressing rod 16 pressed, so that the limit hook 21 is separated from the limit sheet 13, and the writing state is maintained. When the pen head assembly contacts the display screen, under the action of the writing force, the conductive column 6 will retract into the pen body 1. At this time, the length of the pen head assembly is the appropriate use length for the user. Then, the pressing rod 16 is released, and under the action of the reset spring 18, the limit hook 21 is engaged with the limit sheet 13, so as to realize the limit function of the moving shaft 14, and then realize the limit function of the pen head assembly, so as to ensure the stability of the use length of the pen head assembly after adjustment, so that the use length of the pen head assembly can be automatically adjusted according to the writing force of different people.

[0048] When the disc-type pen tip is needed, the threaded ring 7 is first rotated to separate the threaded ring 7 from the conductive column 6. Under the action of the universal ball 17 and the rolling groove, the use angle of the disc-type pen tip can be adjusted arbitrarily, thereby improving the flexibility of use.

[0049] Then the magnetic ring 8 is moved upward, and the magnetic ring 8 is magnetically attracted to the threaded ring 7. At the same time, under the action of the transmission rod 23, the combination head 9 is unfolded to a horizontal state, thereby propping up the elastic membrane 24, so that the elastic membrane 24 forms a disc state, which is convenient for users to browse web pages;

[0050] When a pointed pen tip is needed, the threaded ring 7 is rotated to make the threaded ring 7 threadedly connected to the conductive column 6 to prevent the adapter 15 from rotating, thereby ensuring the stability of the pointed pen tip when in use. The unfolded combination heads 9 are then closed to form a pointed pen tip. In this process, the elastic membrane 24 can be wrapped around the inner side of the combination head 9 again. Under the action of the magnetic rubber patch, the combination head 9 can stably form a pointed pen tip, making it convenient for the user to write.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
