Detailed implementation manners

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the attached drawings). If the specific posture changes, the directional indication will also change accordingly.

[0031] In addition, in the present invention, descriptions such as "first" and "second" are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In the description of the present invention, the meaning of "a plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0032] In the present invention, unless otherwise clearly defined and limited, terms such as "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components, unless otherwise clearly limited. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] In addition, the technical solutions between various embodiments of the present invention can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present invention.

[0034] Touch screens, such as interactive intelligent panels (IIP), are increasingly widely used in home and office scenarios. Touch screens are usually written and interacted with using an electronic pen. However, in related technologies, changing the pen color requires using the corresponding function of a specific application software on the touch screen for replacement, and the operation is not convenient enough.

[0035] For this reason, in some technologies, the color is changed by rotating a color mixing slider ring and the currently selected color is displayed through different LED lights. However, this structure causes the LED lights to be constantly on, with relatively high power consumption, resulting in a lower battery life of the electronic pen.

[0036] In the embodiment of the present application, the electronic pen is provided with a rotating wheel attached with color identifiers and an observation window is provided on the pen barrel. When the rotating wheel rotates to different positions, the color identifier corresponding to that position is exposed to the observation window, enabling the user to intuitively understand the currently selected color. Compared with the related art, there is no need to set up LED lights, thus effectively reducing power consumption and improving the battery life of the electronic pen.

[0037] As Figures 1 to 8 shown, an electronic pen 100, which can be used in conjunction with a touch screen, includes a pen barrel 1, a pen tip 2, a rotating wheel 3 and a controller. The pen barrel 1 is a hollow structure body, which has an installation cavity 11 and an observation window 12 communicating with the installation cavity 11. The installation cavity 11 is surrounded by the barrel wall of the pen barrel 1, and the observation window 12 penetrates the barrel wall. The pen barrel 1 extends along the first direction X, and it has a first end 14 and a second end 15 oppositely arranged in the first direction X. The installation cavity 11 and the observation window 12 are located between the first end 14 and the second end 15. The pen tip 2 can be used for writing on the touch screen, and the pen tip 2 is arranged at the first end 14 of the pen barrel 1. At least a part of the rotating wheel 3 is located in the installation cavity 11 of the pen barrel 1. The rotating wheel 3 is rotationally connected with the pen barrel 1, and the rotating wheel 3 can rotate relative to the pen barrel 1 around a first rotation axis. On the outer peripheral surface of the rotating wheel 3, the rotating wheel has a plurality of color adjustment positions, and each color adjustment position corresponds to a display color. The outer peripheral surface 34 of the rotating wheel 3 also has a plurality of color identifiers 4, and each color identifier 4 corresponds to a color adjustment position. When the rotating wheel 3 rotates to any color adjustment position, the color identifier 4 located at that color adjustment position is exposed to the observation window 12. The controller is arranged on a circuit board in the installation cavity 11 of the pen barrel 1. The controller obtains color adjustment information according to the color adjustment position information of the rotating wheel 3. After the touch screen receives the color adjustment information, it correspondingly adjusts the brush color of the application software on the touch screen, so that the font or line of the currently selected color can be displayed on the touch screen.

[0038] The electronic pen 100 includes a rotating wheel 3 with a plurality of color adjustment positions. By rotating the rotating wheel 3, the adjustment and switching of the color displayed on the touch screen can be realized. By setting the observation window 12, the color identifier 4 corresponding to the selected color adjustment position is exposed to the observation window 12, enabling the user to intuitively understand the currently selected color of the electronic pen 100.

[0039] For the electronic pen 100, the first rotation axis of the rotating wheel 3 can be parallel to the first direction X, and the adjustment and switching of the color of the electronic pen 100 can be realized by rotating the rotating wheel 3 left and right. The first rotation axis of the rotating wheel 3 can also be perpendicular to the first direction X, and the adjustment and switching of the color of the electronic pen 100 can be realized by rotating the rotating wheel 3 forward and backward. The first rotation axis of the rotating wheel 3 can also form an acute angle with the first direction X, and the adjustment and switching of the color of the electronic pen 100 can be realized by tilting and rotating the rotating wheel 3.

[0040] For the electronic pen 100, a part of the rotating wheel 3 can be located inside the installation cavity 11 of the pen barrel 1, while the other part is located outside the pen barrel 1, so as to facilitate the user to rotate the rotating wheel 3 and can appropriately reduce the volume of the installation cavity 11 of the pen barrel 1, thereby making the electronic pen 100 more miniaturized. The rotating wheel 3 can also be entirely located inside the installation cavity 11 of the pen barrel 1. A driving member and a transmission mechanism are separately provided on the pen barrel 1. The user operates the driving member to slide or rotate, and the driving member drives the rotating wheel 3 to rotate around the first rotation axis through the transmission mechanism. By way of example, a pen cap 7 is provided at the second end 15 of the pen barrel 1. The pen cap 7 is rotatably connected to the pen barrel 1, and the pen cap 7 is fixedly connected to the rotating wheel 3. By rotating the pen cap 7, the rotating wheel 3 can rotate relative to the pen barrel 1 around the first rotation axis.

[0041] As Figures 1 to 6 As shown, an electronic pen 100 includes a pen barrel 1, a pen tip 2, a rotating wheel 3, a color identifier 4, and a controller. The pen barrel 1 is a hollow rod-shaped body that extends along the first direction X. The two ends of the pen barrel 1 in the first direction X are respectively a first end 14 and a second end 15. The first end 14 is one end of the pen tip 2 for writing, and the second end 15 is the end far from the pen tip 2. The rod wall of the pen barrel 1 encloses an installation cavity 11. The installation cavity 11 extends longitudinally along the first direction X. An observation window 12 is formed by horizontally penetrating one side of the rod wall, and an operation window 13 is formed on the other side. The observation window 12 and the operation window 13 are both communicated with the installation cavity 11. The observation window 12 and the operation window 13 are oppositely arranged and are respectively located on both sides of the diameter direction of the rotating wheel 3. The diameter direction can be perpendicular to the first direction X, and the first direction X is equivalent to the length direction of the electronic pen 100. The rotating wheel 3 is a cylinder that extends in the first direction X. The rotating wheel 3 is embedded and installed in the installation cavity 11 of the pen barrel 1. The rotating wheel 3 is rotatably connected to the pen barrel 1, so that the rotating wheel 3 can rotate relative to the pen barrel 1 around the first rotation axis. The first rotation axis can be parallel to the first direction X. The color identifier 4 is a color block. There are multiple color blocks, and each color block is pasted and fixed on the outer peripheral surface 34 of the rotating wheel 3. The color blocks are evenly distributed in the same circumference around the first rotation axis. The color blocks can extend along the first direction X, that is, the color blocks can be parallel to each other and are spaced apart in the circumferential direction around the first rotation axis.

[0042] The rotating wheel 3 has a plurality of color mixing positions on its outer peripheral surface, and each color mixing position corresponds to a display color and a color patch. When the rotating wheel 3 rotates to any color mixing position, one color patch is exposed to the observation window 12, and the user can intuitively understand the currently selected color through this observation window 12. At the same time, at least one other color patch is exposed to the operation window 13. Generally, the area of the operation window 13 is larger than the area of the observation window 12, so that at any color mixing position, a plurality of color patches can be exposed to the operation window 13. The shape and size of the operation window 13 can match the shape and size of the rotating wheel 3. On the premise of maintaining the rotation performance of the rotating wheel 3, the gap between the operation window 13 and the rotating wheel 3 is as small as possible. In the first direction X, the length of the observation window 12 can be less than the length of the rotating wheel 3, so that the rotating wheel 3 does not protrude out of the pen shaft 1.

[0043] The controller can obtain color adjustment information according to the color mixing position information of the rotating wheel 3, and the touch screen displays the currently selected color according to this color adjustment information. The display of 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 fonts or lines) can display the currently selected color.

[0044] Furthermore, the electronic pen 100 may further include a pen tip 2, which is used for writing on the touch screen, and the pen tip 2 can be provided at the first end 14 of the pen shaft 1.

[0045] Furthermore, the electronic pen 100 may further include a rotary button 5 and a rotating shaft 6. The rotary button 5 is fixed on the circuit board in the installation cavity 11 of the pen shaft 1 and is located below one end of the rotating wheel 3 close to the first end 14 of the pen shaft 1. The rotary button 5 may have a plurality of rotation gears, and the rotation gears correspond one by one to the color mixing positions of the rotating wheel 3. That is, when the rotating wheel 3 rotates to a color mixing position, the rotary button 5 rotates to a rotation gear. The rotating wheel 3 has a shaft hole 31 penetrating along the first direction X, and the axis of the shaft hole 31 is the first rotation axis. The rotating shaft 6 penetrates downward through the shaft hole 31 of the rotating wheel 3 and is fixed to the rotating wheel 3, and the bottom of the rotating shaft 6 is fixed to the rotatable rotating rod 51 of the rotary button 5. By providing the rotating shaft 6 and the rotary button 5, the rotating wheel 3 is rotatably installed in the installation cavity 11 of the pen shaft 1. In an alternative structure, the top of the rotating shaft 6 can be installed in the installation cavity 11 of the pen shaft 1 through a bearing, and the bottom of the rotating shaft 6 is connected to the rotary button 5, so that the rotating wheel 3 can rotate more smoothly.

[0046] When the user rotates the rotating wheel 3, the rotating wheel 3 drives the rotating rod 51 of the rotary button 5 to rotate through the rotating shaft 6. The rotary button 5 is electrically connected to the controller. The rotary button 5 converts the mechanical signal of the rotation of the rotating wheel 3 into an electrical signal and transmits it to the controller. The controller sends a signal to the touch screen according to this electrical signal to make the touch screen display the currently selected color.

[0047] Further, a plurality of groups of ribs 32 are protruding provided on the outer peripheral surface 34 of the rotating wheel 3. Each group has one or more ribs 32. Each rib 32 extends along the first direction X, and adjacent two groups of ribs 32 are spaced apart. In the circumferential direction around the first rotation axis of the rotating wheel 3, the ribs 32 and the color markings 4 are arranged alternately on the outer peripheral surface 34 of the rotating wheel 3, that is, a group of ribs 32 is provided between two adjacent color markings 4. The rib 32 can be in frictional engagement with the wall of the mounting cavity 11 of the pen barrel 1, so as to increase the frictional force between the rotating wheel 3 and the pen barrel 1, enabling the rotating wheel 3 to effectively maintain the current selected color mixing position. At any color mixing position, at least one group of ribs 32 is in frictional engagement with the wall of the mounting cavity 11.

[0048] Further, the electronic pen 100 further includes a charging interface and a pen cap 7. The charging interface is fixedly provided in the opening 16 at the second end 15 of the pen barrel 1, and the pen cap 7 is detachably connected to the second end 15. The pen cap 7 has an installed state and a removed state. In the installed state, the pen cap 7 covers the second end 15 of the pen barrel 1 and shields the charging interface; in the removed state, the pen cap 7 leaves the second end 15 of the pen barrel 1 and opens the charging interface. By providing the pen cap 7, the charging interface can be effectively protected when the electronic pen 100 is in a non-charging state.

[0049] The pen cap 7 may include a pen cap body 71, a connecting line 72 and a rubber plug 73. The pen cap body 71 can be adaptively covered on the second end 15 of the pen barrel 1. The two ends of the connecting line 72 are respectively connected to the pen cap body 71 and the rubber plug 73. The rubber plug 73 can be inserted into the corresponding socket fixedly provided in the opening 16. Under normal conditions, the rubber plug 73 is inserted and fixed in the opening 16 at the second end 15 of the pen barrel 1, so that the pen cap 7 can be hung on the pen barrel 1. In the installed state, the connecting line 72 is inserted into the opening 16 at the second end 15, and the pen cap body 71 covers the second end 15 and shields the charging interface. In the removed state, the pen cap body 71 is removed from the second end 15 of the pen barrel 1. Since the rubber plug 73 is fixed on the pen barrel 1, the entire pen cap 7 is hung outside the pen barrel 1, that is, the pen cap 7 is hung on the pen barrel 1 through the connecting line 72 and the rubber plug 73. By providing the connecting line 72 and the rubber plug 73, the pen cap 7 will not be separated from the pen barrel 1, effectively avoiding the loss of the pen cap 7.

[0050] Further, the electronic pen 100 may further include a power indicator, which can be used to display the battery status. The power indicator is installed in the installation cavity 11 of the pen barrel 1 and is electrically connected to the controller. Correspondingly, a status window 17 is further formed horizontally through the wall of the pen barrel 1, and the power indicator is exposed to the status window 17. In the first direction X, the status window 17 may be located below the operation window 13. In the diameter direction of the rotating wheel 3, the status window 17 and the operation window 13 may be located on one side of the rotating wheel 3, and the observation window 12 may be located on the other side of the rotating wheel 3. The positions of these windows are set in line with the user's usage habits.

[0051] Referring in combination to Figure 7 and Figure 8 which is another embodiment of the electronic pen 100 of the present application. The electronic pen 100 includes a pen barrel 1, a pen tip 2, a rotating wheel 3, a color identifier 4, a color-changing rod 8 and a pen cap 7. The pen barrel 1 has an installation cavity 11, an operation window 13 and an observation window 12 communicating with the installation cavity 11. The rotating wheel 3 is installed in the installation cavity 11 of the pen barrel 1 and is rotatably connected to the pen barrel 1, so that the rotating wheel 3 can rotate relative to the pen barrel 1 around a first rotation axis, and the first rotation axis is parallel to the first direction X. A plurality of chambers 33 are provided on the end face of the rotating wheel 3 away from the pen tip 2, and the chambers 33 are evenly distributed concentrically around the first rotation axis. Each chamber 33 extends along the first direction X. Each chamber 33 has a chamber bottom, and a window is provided on the outer peripheral surface of the rotating wheel 3 corresponding to each chamber 33. When the color-changing rod 8 is inserted into the chamber 33, a part of the color-changing rod 8 is exposed through the window, forming a color identifier 4, that is, the color of the color-changing rod 8 itself inserted into the chamber 33 serves as the color identifier 4. There are a plurality of color-changing rods 8, and the color-changing rods 8 are rod-shaped bodies extending along the first direction X.

[0052] In some other embodiments, a signal transmitting component may be built in the bottom of each color-changing rod 8, and the signal transmitting component can transmit color information. Each color-changing rod 8 corresponds to one color.

[0053] A color identifier 4 is pasted and fixed on the outer peripheral surface 34 of the rotating wheel 3 corresponding to each chamber 33, so that the chambers 33 and the color identifiers 4 are in one-to-one correspondence. The controller includes a signal receiving component, and the signal receiving component is fixed at a preset position in the installation cavity 11.

[0054] The rotating wheel 3 has a plurality of color mixing positions on its outer peripheral surface. When the rotating wheel 3 rotates to any color mixing position, a color identifier 4 is exposed to the observation window 12, and one or more color identifiers 4 are exposed to the operation window 13. At any color mixing position, the color information transmitted by the color-changing rod 8 in the chamber 33 located at the color mixing position is received by the signal receiving component in the pen barrel 1, and then the touch screen can be controlled to display the currently selected color.

[0055] In this embodiment, a color-changing rod 8 with a built-in signal transmitting component can be inserted into each of the compartments 33. During use, the color-changing rod 8 can be inserted into each of the compartments 33, or only into some of the compartments 33. The number of color-changing rods 8 can be more than the number of compartments 33, so that the appropriate number and appropriate color of the color-changing rods 8 can be selected according to the usage requirements and inserted into the corresponding compartments 33. Correspondingly, the color identifier 4 needs to be replaced, so as to accurately display the currently selected color.

[0056] For the electronic pen 100, it has a rotating wheel 3 that can rotate around a first rotation axis. The rotating wheel 3 has a plurality of color mixing positions and a plurality of color identifiers 4 corresponding to the color mixing positions one by one. When rotated to any color mixing position, the color identifier 4 corresponding to this color mixing position is exposed to the observation window 12, so that it is convenient for the user to intuitively understand the currently selected color. The color identifier 4 can be a color block fixedly pasted on the outer peripheral surface 34 of the rotating wheel 3, or a color block fixedly embedded in the outer peripheral surface 34 of the rotating wheel 3, or a color coating applied to the outer peripheral surface 34 of the rotating wheel 3. The cross-section of the pen barrel 1 can be a regular or irregular shape such as a circle, a square, or a triangle.

[0057] Another aspect of the embodiment of the present application provides an electronic device, including a touch screen and an electronic pen 100. The electronic pen 100 is detachably installed on the touch screen, and the controller of the electronic pen 100 can be wirelessly connected to the touch screen. The touch screen can be an interactive intelligent panel (IIP), such as an infrared touch interactive intelligent panel.
