Technical Field

[0001] The present invention relates to the technical field of touch devices, and in particular to an electronic pen and an electronic device. Background Art

[0002] Touch screens, such as interactive intelligent panels (IIPs), are increasingly used in homes and offices. Touch screens typically use electronic pens for writing and interaction. However, in related technologies, changing the pen color requires accessing the corresponding function in the specific application software on the touch screen, which is inconvenient. Summary of the Invention

[0003] The embodiments of the present application provide an electronic pen and an electronic device capable of changing color.

[0004] The present invention provides an electronic pen that can be used in conjunction with a touch screen, including:

[0005] The pen holder has a mounting cavity and an observation window communicating with the mounting cavity, and the two ends of the pen holder in the first direction are respectively a first end and a second end;

[0006] a pen tip, the pen tip being provided at the first end;

[0007] a pen cap, which is disposed at the second end and is movably connected to the pen shaft so as to be movable along a first direction;

[0008] a rotating color cylinder, the rotating color cylinder being at least partially disposed within the mounting cavity, the rotating color cylinder being rotatably connected to the pen holder and being rotatable about a first rotation axis, the rotating color cylinder having a plurality of color adjustment positions and color markings corresponding to the color adjustment positions, each color adjustment position corresponding to a display color, and at any color adjustment position, the color marking corresponding to the color adjustment position being exposed to the observation window;

[0009] a transmission mechanism connecting the pen cap and the rotating color cylinder, the transmission mechanism being capable of converting the movement of the pen cap along a first direction into the rotation of the rotating color cylinder about a first rotation axis;

[0010] The controller is arranged in the installation cavity and is configured to control the touch screen to display the currently selected color according to the color adjustment position.

[0011] In some embodiments, the first rotation axis is parallel or perpendicular to the first direction.

[0012] In some embodiments, the transmission mechanism includes a sleeve, a pressure rod, a push rod, and an elastic member. The sleeve is fixed to the pen holder. The inner circumferential surface of the sleeve is provided with multiple groups of guide members protruding along its circumference. A first guide groove extending in a first direction is formed between two adjacent groups of guide members. Each group of guide members includes a first guide block and a second guide block. The first guide block has a first guide inclined surface extending in the rotation direction of the rotating color drum and a stop surface forming a sharp angle with the first guide inclined surface. The second guide block has a second guide inclined surface extending in the rotation direction and a second guide groove extending in the first direction. The second guide slope is connected to the stop surface. The end surface of the pressure rod facing the push rod is provided with a circle of lower meshing teeth. The end surface of the push rod facing the pressure rod is provided with a circle of upper meshing teeth, and the side surface of at least some of the upper meshing teeth is provided with a third guide block having a third guide slope. The upper meshing teeth and the lower meshing teeth mesh. In the first direction, the push rod is supported by an elastic member on the rotating color drum. The push rod is connected to the rotating color drum for anti-rotation. Each first guide groove and each second guide groove are plugged into and engaged with the pressure rod. At any color adjustment position, the third guide block is positioned in the first guide groove or the stop surface. By providing multiple guide blocks and multiple guide grooves, the linear motion and rotational motion of the push rod can be guided.

[0013] In some embodiments, the first guiding bevel, the second guiding bevel, and the third guiding bevel are all helical surfaces. By providing matching helical surfaces, the rotation of the push rod is made more stable.

[0014] In some embodiments, a circle of bumps is protruded from the outer circumference of the pressure rod, and each bump is inserted into the corresponding first guide groove or second guide groove. Through the plug-in fit between the bumps and the guide grooves, the pressure rod can only move linearly along the first direction and cannot rotate with the push rod.

[0015] In some embodiments, the upper meshing teeth are sequentially connected, and a third guide block is provided between each upper meshing tooth. The third guide slope is provided on the third guide block, and the upper meshing surface of the upper meshing teeth connected to the third guide block smoothly transitions to the third guide slope. By providing the sequentially connected upper meshing teeth, the upper meshing teeth can mesh with the lower meshing teeth of the push rod, thereby making the rotation of the push rod more stable.

[0016] In some embodiments, the electronic pen further includes a rotation button, which is fixed within the mounting cavity and electrically connected to the controller. The rotation button is also fixedly connected to the rotating color drum so as to rotate synchronously. The rotation button can convert a mechanical signal generated by the rotating color drum into an electrical signal.

[0017] In some embodiments, the color identification is a color block, which is bonded and fixed to the outer surface of the rotating color cylinder; or, the color identification is a color block, which is embedded and installed on the outer surface of the rotating color cylinder; or, the color identification is a color coating, which is applied to the outer surface of the rotating color cylinder.

[0018] In some embodiments, the pen holder further has a status window, and the electronic pen further includes a battery indicator light, which is exposed in the status window. By providing the battery indicator light and the status window, the charging status of the electronic pen can be indicated.

[0019] An electronic device comprises a touch screen and an electronic pen, wherein the electronic pen is detachably connected to the touch screen.

[0020] Beneficial effects: By setting a linked pen cap and rotating color barrel, when the pen cap is pressed, the rotating color barrel rotates, thereby adjusting the color displayed on the touch screen; by setting an observation window and color label, when the rotating color barrel is rotated into place, the corresponding color label is exposed in the observation window, allowing the user to intuitively understand the currently selected color; there is no need to set a constantly on light, which saves energy consumption and improves the battery life of the electronic pen.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0034] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0035] In addition, the terms "first," "second," and so on, used in this disclosure are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referenced. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this disclosure, "plurality" means at least two, such as two or three, unless otherwise specifically defined.

[0036] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is mutually contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0038] Touch screens are increasingly used in homes and offices, and are typically used for writing and interacting with electronic pens. However, in related technologies, changing the pen color requires using the corresponding function of the specific application software on the touch screen, which is inconvenient.

[0039] To this end, some technologies change the color by rotating a color adjustment slip ring and display the currently selected color through different LED lights. However, this structure requires the LED lights to be always on, which consumes a lot of power and results in a low battery life of the electronic pen.

[0040] The electronic pen in the embodiment of the present application is provided with a linked pen cap and a rotating color cylinder, the rotating color cylinder has a color mark, and an observation window is provided on the pen body. When the pen cap is pressed, the pen cap can rotate with the rotating color cylinder. When the rotating color cylinder rotates to a different color adjustment position, the color mark corresponding to the color adjustment position is exposed to the observation window, so that the user can intuitively understand the currently selected color. Compared with the related art, there is no need to set an LED light, thereby effectively reducing power consumption and improving the battery life of the electronic pen.

[0041] like Figures 1 to 9As shown, an electronic pen 100, capable of being used with a touch screen, includes a pen body 1, a pen tip 2, a pen cap 3, a rotating color drum 4, a transmission mechanism 5, and a controller. The pen body 1 is a hollow structure having a mounting cavity 11 and an observation window 12 connected to the mounting cavity 11. The mounting cavity 11 is enclosed by the wall of the pen body 1, and the observation window 12 extends through the wall. The pen body 1 extends along a first direction X and has a first end 13 and a second end 14 disposed opposite each other in the first direction X. The mounting cavity 11 and the observation window 12 are located between the first end 13 and the second end 14. The pen tip 2 is capable of writing on a touch screen and is disposed at the first end 13 of the pen body 1. The pen cap 3 is disposed at the second end 14 of the pen body 1 and is movably connected to the pen body 1, enabling reciprocal movement relative to the pen body 1 along the first direction X. At least a portion of the rotating color cylinder 4 is located within the mounting cavity 11 of the penholder 1. The rotating color cylinder 4 is rotatably connected to the penholder 1 and is capable of rotating relative to the penholder 1 about a first rotation axis Z. Along its rotational trajectory, the rotating color cylinder 4 has multiple color adjustment positions, each corresponding to a displayed color. The outer circumference of the rotating color cylinder 4 also has multiple color markings 40, each corresponding to a color adjustment position. When the rotating color cylinder 4 rotates to any color adjustment position, the color marking at that position is exposed through the viewing window 12. A transmission mechanism 5 connects the pen cap 3 and the rotating color cylinder 4. When the pen cap 3 is pressed, the pen cap 3 drives the rotating color cylinder 4 to rotate about the first rotation axis Z via the transmission mechanism 5. A controller is located on a circuit board within the mounting cavity 11 of the penholder 1. The controller obtains color adjustment information based on the color adjustment position information of the rotating color cylinder 4. Upon receiving this color adjustment information, the touch screen adjusts the brush color of the application software on the touch screen accordingly, thereby displaying the font or line of the currently selected color on the touch screen.

[0042] The electronic pen 100 includes a pen cap 3 and a rotating color drum 4 that is linked to the pen cap 3. Pressing the pen cap 3 rotates the color drum 4, thereby adjusting and switching the color displayed on the touch screen. A viewing window 12 is provided to expose a color marker 40 corresponding to the selected color adjustment position, allowing the user to intuitively understand the currently selected color of the electronic pen 100.

[0043] In the electronic pen 100, the first rotation axis Z of the rotating color drum 4 can be parallel to the first direction X. The pen cap 3 drives the rotating color drum 4 in a unidirectional left-right rotation via the transmission mechanism 5 to adjust and switch the color of the electronic pen 100. The first rotation axis Z of the rotating color drum 4 can also be perpendicular to the first direction X. The pen cap 4 drives the rotating color drum 4 in a unidirectional forward-backward rotation via the transmission mechanism 5 to adjust and switch the color of the electronic pen 100. The first rotation axis Z of the rotating color drum 4 can also form an acute angle with the first direction X. The pen cap 3 drives the rotating color drum 4 in a tilted rotation via the transmission mechanism 5 to adjust and switch the color of the electronic pen 100.

[0044] For the electronic pen 100 , the rotating color cylinder 4 can be located entirely in the mounting cavity 11 of the pen barrel 1 ; or a portion of the rotating color cylinder 4 can be located in the mounting cavity 11 of the pen barrel 1 , while the other portion is located outside the pen barrel 1 , thereby appropriately reducing the volume of the mounting cavity 11 of the pen barrel 1 .

[0045] like Figures 1 to 4 、 Figure 10 As shown, an electronic pen 100 includes a pen body 1, a pen tip 2, a pen cap 3, a rotating color drum 4, a transmission mechanism 5, and a controller. The pen body 1 is a hollow rod-shaped body extending along a first direction X. The pen body 1 has a first end 13 and a second end 14 at its ends in the first direction X. The first direction X corresponds to the length of the electronic pen 100. The first end 13 is the end of the pen tip 2 used for writing, and the second end 14 is the end away from the pen tip 2. The pen tip 2 is used for writing on a touch screen and can be mounted at the first end 13 of the pen body 1. The wall of the pen body 1 encloses a mounting cavity 11. The mounting cavity 11 extends longitudinally along the first direction X. An observation window 12 is formed transversely through one side of the wall. The observation window 12 is connected to the mounting cavity 11 and is located on one side of the diameter of the rotating color drum 4, which can be perpendicular to the first direction X. The pen cap 3 is mounted at the second end 14 of the pen barrel 1 and is movably connected to the pen barrel 1, enabling movement in a first direction X. The rotating color barrel 4 is a cylindrical body extending in the first direction X. The rotating color barrel 4 is mounted within the mounting cavity 11 of the pen barrel 1 and is rotatably connected to the pen barrel 1, enabling rotation relative to the pen barrel 1 about a first rotation axis Z. The first rotation axis Z may be parallel to the first direction X. The color marking 40 is a color block. Multiple color blocks are attached to the outer surface of the rotating color barrel 4. The color blocks may be uniformly distributed circumferentially about the first rotation axis Z. The color blocks may extend in the first direction X, i.e., parallel to each other and sequentially distributed circumferentially about the first rotation axis Z. A transmission mechanism 5 connects the pen cap 3 and the rotating color barrel 4, converting the linear motion of the pen cap 3 in the first direction X into rotational motion of the rotating color barrel 4 about the first rotation axis Z.

[0046] The rotating color drum 4 has multiple color adjustment positions along its rotational trajectory, each corresponding to a displayed color and a color block. When the rotating color drum 4 reaches any color adjustment position, only one color block is exposed to the viewing window 12, allowing the user to intuitively understand the currently selected color. In the first direction X, the length of the viewing window 12 can be shorter than the length of the rotating color drum 4.

[0047] The controller can obtain color adjustment information based on the color adjustment position information of the rotating color drum 4, and the touch screen displays the currently selected color based on the color adjustment information. Displaying the currently selected color means that when the electronic pen 100 writes on the touch screen, the content written on the touch screen (such as font or line) can display the currently selected color.

[0048] like Figures 5 to 9 As shown, the transmission mechanism 5 includes a sleeve 6, a pressure rod 7, a push rod 8 and an elastic member 9. The sleeve 6 is a cylindrical body that penetrates in the first direction X. Its inner circumferential surface is provided with a plurality of groups of guide members 61 protruding along the circumferential direction. Each group of guide members 61 is evenly spaced in the circumferential direction. A first guide groove 62 is formed between two adjacent groups of guide members 61. The first guide groove 62 extends along the first direction X and has a groove bottom in the first direction X. Each group of guide members 61 includes a first guide block 63 and a second guide block 64. In the first direction X, the end surface of the first guide block 63 away from the pen cap 3 is a first guide slope 631, and the end surface of the second guide block 64 away from the pen cap 3 is a second guide slope 641. The first guide slope 631 and the second guide slope 641 both extend along the rotation direction of the rotating color drum 4. The rotation direction is as shown in FIG. Figure 6 The first and second guide bevels 631 and 641 extend obliquely downward along the rotational direction of the rotating color drum 4, with the side closer to the pen tip 2 as the top and the side closer to the pen cap 3 as the bottom. For any set of guide members 61, the lower end of the second guide bevel 641 is connected to the first guide block 63, the upper end of the second guide bevel 641 engages with an adjacent first guide groove 62, and the lower end of the first guide bevel 631 engages with another adjacent first guide groove 62. The lower end of the second guide bevel 641 is located below the upper end of the first guide bevel 631. The second guide bevel 641 extends to the side of the first guide block 63, which serves as a stop surface 632. The stop surface 632 extends in the first direction X and forms a sharp angle with the first guide bevel 631. The first and second guide bevels 631 and 641 can be helical surfaces with a certain lead angle.

[0049] The second guide block 64 has a second guide groove 642 extending along the first direction X. In the first direction X, the second guide slope 641 is located at the mouth of the second guide groove 642 , and the second guide groove 642 has a groove bottom. In the rotational direction of the rotating color drum 4 , the first guide blocks 63 and the second guide blocks 64 are alternately arranged, and the first guide grooves 62 and the second guide grooves 642 are alternately arranged.

[0050] like Figures 7 to 10As shown, the pressure rod 7 is fixedly connected to the pen cap 3. A ring of lower meshing teeth 71 protrudes from the end surface of the pressure rod 7, located in the first direction X and proximate to the push rod 8. Each lower meshing tooth 71 is sequentially connected and surrounds the first rotation axis Z. Each lower meshing tooth 71 has two lower meshing surfaces 711 forming a sharp angle, giving the lower meshing teeth 71 a V-shape. The push rod 8 is anti-rotationally connected to the rotating color drum 4, enabling synchronous rotation of the push rod 8 and the rotating color drum 4 about the first rotation axis Z. A ring of upper meshing teeth 81 protrudes from the end surface of the push rod 8, located in the first direction X and proximate to the push rod 7, surrounding the first rotation axis Z. The upper meshing teeth 81 are capable of meshing with the lower meshing teeth 71. The push rod 8 also includes a third guide block 82 radially projecting from at least a portion of the upper meshing teeth 81. The third guide block 82 has a third guide slope 821 that smoothly transitions from the third guide slope 821 to the corresponding upper meshing teeth 811 of the upper meshing teeth 81. The elastic member 9 is capable of telescopic deformation in a first direction X. The push rod 8 is elastically supported on the rotating color cylinder 4 in the first direction X by the elastic member 9. The push rod 8 can both linearly move relative to the rotating color cylinder 4 in the first direction X and rotate with the rotating color cylinder 4 about the first rotation axis Z. The rotating color cylinder 4 is positioned within the pen holder 1 in the first direction X. That is, the rotating color cylinder 4 cannot linearly move relative to the pen holder 1 in the first direction X.

[0051] The pressure rod 7 engages with both the first guide groove 62 and the second guide groove 642. During the process of pressing the pen cap 3 to adjust the color, the pressure rod 7 does not disengage from the first guide groove 62 or the second guide groove 642, allowing the pressure rod 7 to move only linearly along the first direction X. For any third guide block 82, in the current color adjustment position, the third guide block 82 is positioned by the first guide groove 62; in the next color adjustment position, the third guide block 82 is positioned by the stop surface 632.

[0052] The color mixing process is illustrated using one of the third guide blocks 82 as an example. To adjust the color, the cap 3 is pressed. Initially, the pressure rod 7 moves the push rod 8 linearly in the first direction X. During this phase, the lower meshing teeth 71 engage with the upper meshing teeth 81, and the third guide block 82 is positioned within the first guide slot 62, enabling only linear movement of the push rod 8 and preventing rotation. Furthermore, the elastic member 9 is compressed. After the push rod 8 has completely disengaged the third guide block 82 from the first guide slot 62, the cap 3 is released. Under the elastic force of the elastic member 9, the push rod 8 and the rotating color drum 4 rotate in the rotational direction. During this rotation, the third guide slope 821 of the third guide block 82 moves along the second guide slope 641 of the second guide block 64 until the third guide block 82 is positioned against the stop surface 632. Press the pen cap 3 again, and the pressure rod 7 pushes the push rod 8 to move linearly, compressing the elastic member 9. When the third guide block 82 disengages from the stop surface 632, the pen cap 3 is released. Under the elastic force of the elastic member 9, the push rod 8 continues to rotate in the rotation direction, and the third guide surface 821 of the third guide block 82 moves along the first guide inclined surface 631 of the first guide block 63 until the third guide block 82 falls into the adjacent first guide groove 62.

[0053] like Figures 5 to 7 As shown, in the illustrated embodiment, to accurately guide the movement of the pressure rod 7, a circle of protrusions 72 is formed on the outer circumference of the pressure rod 7. Each protrusion 72 engages with its corresponding first guide groove 62 or second guide groove 642. When the pen cap 3 reciprocates in the first direction X, each protrusion 72 remains within its corresponding guide groove, allowing the pressure rod 7 to move only in a straight line.

[0054] like Figure 9 and Figure 10 As shown, to prevent relative rotation between the push rod 8 and the rotating color drum 4, a protruding anti-rotation block 83 is provided on the outer circumference of the push rod 8. Correspondingly, a concave anti-rotation groove 41 is provided on the inner circumference of the rotating color drum 4. The anti-rotation block 83 engages with the corresponding anti-rotation groove 41. In the first direction X, the length of the anti-rotation groove 41 is greater than the length of the anti-rotation block 83, allowing the push rod 8 to move linearly along the anti-rotation groove 41.

[0055] like Figure 8 and Figure 9As shown, in the illustrated embodiment, the push rod 8 has a circle of upper meshing teeth 81 around the first rotation axis Z. The upper meshing teeth 81 are connected in sequence, and a third guide block 82 is provided between each upper meshing tooth 81. The third guide block 82 has a third guide bevel 821. The third guide bevel 821 smoothly transitions with the upper meshing surface 811 of the upper meshing tooth 81 to which it is connected, forming an integral guide bevel. The upper meshing surface 811 can mate with the lower meshing surface 711 of the lower meshing tooth 71. The third guide bevel 821 matches the shape of the first guide bevel 631 or the second guide bevel 641, and the third guide bevel 821 is also a helical surface. In some alternative structures, the push rod 8 has a circle of upper meshing teeth 81 around the first rotation axis Z, the upper meshing teeth 81 are evenly spaced, and the side surface of each upper meshing tooth 81 has a third guide block 82 protruding radially, and the end surface of the third guide block 82 is the third guide bevel 821. The third guide block 82 is fixed integrally with its corresponding upper meshing tooth 81. The third guide block 82 can be integrally formed with the upper meshing tooth 81, such as injection molding or machining, or the third guide block 82 can be fixed integrally with the upper meshing tooth 81 by bonding, welding or fastener connection.

[0056] In the illustrated embodiment, the rotating color drum 4 is a cylindrical body with a bottom. An elastic member 9 is disposed within the rotating color drum 4. The upper portion of the push rod 8 is inserted into the rotating color drum 4. The elastic member 9 is arranged along a first direction X, with its ends connecting the bottom of the rotating color drum 4 and the upper portion of the push rod 8, respectively. The elastic member 9 is formed of a spring or an elastic sleeve. The lower portion of the push rod 8 is provided with a mating rod 84 extending along the first direction X. The mating rod 84 is pluggably engaged with the upper portion of the pressure rod 7. The lower portion of the pressure rod 7 is inserted through the sleeve 6 and then securely connected to the pen cap 3.

[0057] Furthermore, the electronic pen 100 may also include a rotary button. The rotary button is fixed to a circuit board within the mounting cavity 11 of the pen barrel 1 and may be located between the pen tip 2 and the rotating color barrel 4. The rotary button's rotatable shaft is fixed to the rotating color barrel 4, allowing the rotating color barrel 4 and the shaft to rotate synchronously. The rotary button may have multiple rotational positions, each corresponding to a color adjustment position of the rotating color barrel 4. That is, each time the rotating color barrel 4 rotates to a color adjustment position, the rotary button rotates to a corresponding rotational position. When the rotating color barrel 4 rotates, the rotating color barrel 4 rotates with the rotary button's shaft. The rotary button is electrically connected to a controller, converting the mechanical signal generated by the rotating color barrel 4's rotation into an electrical signal and transmitting it to the controller. The controller then transmits a signal to the touch screen based on the electrical signal, causing the touch screen to display the currently selected color.

[0058] Furthermore, the electronic pen 100 may also include a power indicator light, which can be used to display the battery status. This power indicator light is mounted within the mounting cavity 11 of the pen barrel 1 and is electrically connected to the controller. Correspondingly, a status window 15 is formed transversely through the wall of the pen barrel 1, through which the power indicator light is exposed. The status window 15 and the observation window 12 can be located on one side of the rotating color barrel 4 in the diametrical direction of the rotating color barrel 4. The positioning of these windows is tailored to user preferences.

[0059] The electronic pen 100 includes a rotating color barrel 4 that can rotate about a first rotation axis Z. The rotating color barrel 4 has multiple color adjustment positions and multiple color markers 40 corresponding to each color adjustment position. When the pen is rotated to any color adjustment position, the color marker 40 corresponding to that position is exposed through the viewing window 12, allowing the user to intuitively understand the currently selected color. The color marker 40 can be a color block affixed to the outer circumference of the rotating color barrel 4, a color block embedded in the outer circumference of the rotating color barrel 4, or a color coating applied to the outer circumference of the rotating color barrel 4.
