[0028] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0030] At present, display screens are widely used in conference and teaching scenarios, and display screens are also equipped with smart pens (such as capacitive pens, pressure-sensitive pens, etc.) to facilitate users to write on the display screens through the smart pens. During the writing process, users often need to change the handwriting color to distinguish the written content for easy reading. The prior art changes the handwriting color by operating the function keys on the smart pen accordingly, but after the operation is completed, the user needs to try writing to know which color has been changed. In this way, the user needs to try writing multiple times to change the desired handwriting color, which is not convenient enough.

[0031] In order to solve the above technical problems, the smart pen of the present application is provided with a color bar with multiple color zones. The color bar can reveal the corresponding color zone when the smart pen changes the handwriting color. This makes it easy for users to observe and determine the current handwriting color. There is no need to determine the current handwriting color through trial writing, which is very convenient and quick.

[0032] The smart pen provided in the embodiment of the present application will be described in detail below with reference to the accompanying drawings.

[0033] like Figure 2 As shown, the smart pen 100 proposed in the present application includes a pen body 10 , a color change module 20 , a color change key 30 and a color bar 40 .

[0034] Among them, the pen body 10 is the main part of the smart pen 100. Specifically, the pen body 10 usually includes a pen shell and a pen core installed in the pen shell. The pen shell is generally also equipped with a circuit board 60, a battery, a mounting bracket 50, etc. The specific structure of the pen body 10 can be flexibly designed according to actual needs and is not specifically limited here.

[0035] It should be noted that, in this embodiment, Figure 3 As shown, the side wall of the pen body 10 is provided with an observation hole 11. Specifically, as shown in the figure, the pen body 10 is a columnar structure, and the specific shape can be a cylinder or a multi-prism. The interior of the pen body 10 is hollow and has a mounting cavity 12. Figure 8 The mounting cavity 12 is used to mount the pen core, the circuit board 60, the mounting bracket 50, etc. The side wall of the pen body 10 has an observation hole 11, which is connected to the mounting cavity 12. The observation hole 11 is used to allow the color area 41 on the color strip 40 to be exposed. For details, please refer to the following description. In short, the observation hole 11 is mainly to facilitate the user to observe the color area 41 on the color strip 40. Therefore, the size and shape of the observation hole 11 can be flexibly set according to needs, and no specific limitation is made here. For example, the observation hole 11 can be a waist-shaped hole, a circular hole, an elliptical hole, a polygonal hole, etc.

[0036] like Figure 8 As shown, the color changing module 20 is installed in the pen body 10, and as shown in FIG. Figure 4 As shown, the color changing module 20 is provided with a plurality of color gears 21 , each color gear 21 corresponds to a handwriting color; the color changing module 20 is also used to communicate with the display screen 200 to transmit the gear information of the current color gear 21 to the display screen 200 .

[0037] Specifically, the color-changing module 20 may have various structural forms.

[0038] For example, in one embodiment, the color-changing module 20 may include a switch 22 and a plurality of circuit structures (such as conductive connectors), the plurality of circuit structures respectively corresponding to a plurality of color gears 21, the switch 22 may be moved between the plurality of circuit structures, and the switch 22 may conduct any circuit structure. The circuit structure after conduction generates a corresponding color electrical signal, and the color electrical signals generated by different circuit structures are also different. The color electrical signal is transmitted to the display screen 200 through the communication module, and the display screen 200 adjusts the corresponding handwriting color according to the color electrical signal, that is, different color gears 21 correspond to different handwriting colors.

[0039] Alternatively, in another embodiment, the color changing module 20 may include a switching switch 22 and multiple sensors (such as infrared sensors), the multiple sensors respectively corresponding to multiple color gears 21, the switching switch 22 moves between the multiple sensors, any one of the sensors can generate a color sensing signal when the switching switch 22 is close, and the color sensing signals generated by different sensors are also different. The color sensing signal is transmitted to the display screen 200 through the communication module, and the display screen 200 calls out the corresponding handwriting color according to the color sensing signal, that is, different color gears 21 correspond to different handwriting colors.

[0040] In short, the specific structure of the color changing module 20 can be flexibly designed according to needs, as long as it can form multiple color gears 21 and can transmit the gear information of the current color gear 21 to the display screen 200.

[0041] It should be noted that the “switch 22 ” mentioned in the above two embodiments may be a structure provided by the color-changing module 20 , or may be formed by a partial structure on the color-changing key 30 .

[0042] In addition, the color-changing module 20 may have its own communication function (i.e., be equipped with a communication module), or it may be connected to the circuit board 60 in the smart pen 100 , and then transmit the gear information of the color gear 21 to the circuit board 60 , and then the circuit board 60 transmits the gear information to the display screen 200 .

[0043] After the design of the color changing module 20 is completed, the display screen 200 may pre-store corresponding handwriting color options, so that after receiving the gear information of the color gear 21, the corresponding handwriting color can be quickly called out to improve the efficiency of changing the handwriting color.

[0044] like Figure 5 and Figure 8 As shown, the color-changing key 30 is movably mounted on the pen body 10 , and the color-changing key 30 is transmission-connected with the color-changing module 20 . The color-changing key 30 is used to move relative to the pen body 10 to trigger the color-changing module 20 to switch the color gear 21 .

[0045] Specifically, as described above, when the color-changing module 20 has a switching switch 22, the color-changing key 30 can be connected to the switching switch 22. Then, the color-changing module 20 is triggered to switch the color gear 21 by driving the switching switch 22 to move. If the color-changing module 20 does not have a switching switch 22, the color-changing key 30 can be partially extended into the color-changing module 20. For example, the color-changing module 20 is provided with a conductive part, and the conductive part is used to conduct any circuit structure in the color-changing module 20, thereby triggering the color-changing module 20 to switch the color gear 21.

[0046] It should be noted here that the specific movable installation method of the color change key 30 needs to be set to adapt to the switching method of the color gear 21. For example, when multiple color gears 21 are arranged in a straight line, the color change key 30 can be slidably installed on the pen body 10, and the color change key 30 slides along the arrangement direction of the multiple color gears 21, which makes it easy to trigger the color change module 20 to switch the color gear 21.

[0047] For another example, when multiple color modules are arranged along an arc direction, the color change key 30 can be rotatably mounted on the pen body 10 , and the color change key 30 rotates along the arrangement direction of the multiple color gears 21 to be able to rotate to a position corresponding to each color gear 21 .

[0048] like Figure 6 and Figure 8 As shown, the color bar 40 is movably installed in the pen body 10, and the color bar 40 is in transmission connection with the color change key 30. The color bar 40 is also provided with a plurality of color areas 41, and the plurality of color areas 41 correspond to the plurality of color gears 21. When the color change key 30 moves relative to the pen body 10, the color change key 30 also drives the color bar 40 to move relative to the pen body 10, so that the color area 41 corresponding to the current color gear 21 is exposed in the viewing hole 11.

[0049] Specifically, in the present embodiment, the color strip 40 may be a metal plate, a plastic plate, a cardboard, etc., and a plurality of color areas 41 are provided on the color strip 40, and the plurality of color areas 41 correspond one-to-one to the plurality of color gears 21. For example, when there are four color gears 21, and the order of the four color gears 21 is black, white, red, and green, the color strip 40 also has four color areas 41, and the colors and order of the four color areas 41 are also black, white, red, and green. In this way, the current handwriting color can be accurately reflected through the color strip 40.

[0050] The color strip 40 is movably installed in the pen body 10, and the color strip 40 is transmission-connected with the color-changing key 30, so that when the color-changing key 30 moves relative to the pen body 10 to switch the color gear 21, the color strip 40 can also follow the movement, so that the color area 41 on the color strip 40 corresponding to the current color gear 21 can move to the observation hole 11 and appear in the observation hole 11.

[0051] It should be noted that the activity of the color bar 40 in the pen body 10 can be the same as or different from the color change key 30. For example, when the color change key 30 triggers the color change module 20 to switch the color gear 21 by sliding, the color bar 40 can be directly connected to the color change key 30 and slide along with the color change key 30, thereby causing the corresponding color area 41 to slide to the observation hole 11.

[0052] Alternatively, when the color-changing key 30 triggers the color-changing module 20 to switch the color gear 21 by sliding, the color strip 40 can be connected to the color-changing key 30 through a transmission member such as a worm, a gear, or a rack. When the color-changing key 30 slides, the color strip 40 rotates relative to the pen body 10 under the transmission of the transmission member, thereby transmitting the corresponding color area 41 to the observation hole 11.

[0053] In short, the color strip 40 can slide or rotate with the color-changing key 30, or can perform a movement different from the color-changing key 30 under the transmission of the transmission member. As long as the color-changing key 30 triggers the color-changing module 20 to switch the color gear 21, the corresponding color area 41 on the color strip 40 can move to the observation hole 11 and appear through the observation hole 11.

[0054] In summary, it can be understood that the smart pen 100 of the present application is provided with a color bar 40, and a plurality of color areas 41 are provided on the color bar 40, and the plurality of color areas 41 correspond to the plurality of color gears 21 of the color-changing module 20 one by one, and the color bar 40 is movably installed in the pen body 10 and is in transmission connection with the color-changing key 30, so that any color area 41 can be revealed through the observation hole 11 provided on the pen body 10. Therefore, when the user switches the color gear 21 of the color-changing module 20 (that is, switches the handwriting color) by driving the color-changing key 30 to move, the color-changing key 30 will also drive the color bar 40 to move, so that the color area 41 on the color bar 40 corresponding to the handwriting color is revealed in the observation hole 11 of the pen body 10, so that the user can easily know which handwriting color is switched to after each operation, and does not need to determine the current handwriting color through trial writing, which is very convenient and quick.

[0055] Optionally, in one embodiment, as Figure 4 As shown, the color changing module 20 is provided with a switch 22, and the switch 22 is used to switch the color gear 21. The plurality of color gears 21 are arranged along the length direction of the pen body 10, that is, the switch 22 needs to be moved along the length direction of the pen body 10 to switch the color gear 21. Figure 8 As shown, the color-changing key 30 is also slidably mounted on the side wall of the pen body 10 along the length direction of the pen body 10 , and the color-changing key 30 is connected to the switching switch 22 , so that the user can switch the handwriting color by sliding the color-changing key 30 .

[0056] It can be understood that in this embodiment, the color-changing key 30 switches the handwriting color by sliding, which not only has a simple structure but also is convenient for users to operate, further improving the convenience of changing the handwriting color.

[0057] It should be noted here that the connection method between the color change key 30 and the switching switch 22 can be snap connection, screw connection, bonding, magnetic connection, etc., and the specific method can be flexibly selected according to needs, as long as the color change key 30 can stably drive the switching switch 22 to move.

[0058] For example, optionally, in one embodiment, Figure 3 As shown, the pen body 10 is provided with a mounting cavity 12, and the side wall of the pen body 10 is provided with a first assembly opening 13 communicating with the mounting cavity 12. Figure 8 As shown, the color changing module 20 is installed in the installation cavity 12, and the switching switch 22 and the plurality of color gears 21 are arranged corresponding to the first assembly port 13. Figure 5 and Figure 8 The color-changing key 30 is disposed corresponding to the first assembly port 13 , and a first plug-in portion 31 is disposed on a surface of the color-changing key 30 facing the first assembly port 13 , and the first plug-in portion 31 is plugged and matched with the switching switch 22 .

[0059] That is, in this embodiment, the color-changing key 30 and the switching switch 22 are connected by plugging. During assembly, only the first plug-in portion 31 of the color-changing key 30 needs to be plugged into the switching switch 22, which is very convenient for assembly and helps to improve assembly efficiency.

[0060] It should be noted that the first plug-in portion 31 can be a plug-in hole or a plug-in rod, and the specific structural form can be flexibly selected according to needs. Figure 8 In the structural scheme shown, the first plug-in portion 31 is a plug-in hole, and the switch 22 is plugged into the plug-in hole.

[0061] Optionally, in one embodiment, the color-changing key 30 triggers the color-changing module 20 to switch the color position 21 by sliding. Figure 6 and Figure 8 The color strip 40 is slidably installed in the installation cavity 12, and the color strip 40 is provided with a second plug-in portion 42, and the second plug-in portion 42 is arranged corresponding to the first assembly port 13. The color change key 30 is also provided with a third plug-in portion 32 on the side surface facing the first assembly port 13, and the third plug-in portion 32 is plugged and matched with the second plug-in portion 42.

[0062] That is, in this embodiment, the color change key 30 and the color strip 40 are both slidably mounted on the pen body 10, which can simplify the connection structure between the color change key 30 and the color strip 40. In this embodiment, the color change key 30 and the color strip 40 are also connected by plugging, so that during assembly, the color change key 30 can be synchronously connected with the switch 22 and the color strip 40, reducing the connection operations required during assembly, thereby further improving the assembly efficiency.

[0063] It should be noted that one of the second plug-in portion 42 and the third plug-in portion 32 can be a plug-in hole and the other can be a plug-in rod. Figure 8In the structural solution shown, the second plug-in portion 42 is a plug-in hole, the third plug-in portion 32 is a plug-in rod, and the third plug-in portion 32 is plugged into the second plug-in portion 42 .

[0064] Further, such as Figure 8 As shown, the smart pen 100 also includes a mounting bracket 50, which is fixed in the mounting cavity 12. The mounting bracket 50 is provided with a second assembly port 521, and the second assembly port 521 is arranged opposite to the first assembly port 13; the mounting bracket 50 is also provided with a guide groove 522, and the color strip 40 is slidably installed in the guide groove 522, and the second plug-in portion 42 is arranged corresponding to the second assembly port 521.

[0065] Specifically, in this embodiment, Figure 2 As shown, the mounting bracket 50 includes a first bracket 51 and a second bracket 52 which are detachably connected, the circuit board 60 is mounted on the first bracket 51, and the color changing module 20 is mounted on the circuit board 60. The second bracket 52 is mounted on the first bracket 51, and as shown in FIG. Figure 7 As shown, the second bracket 52 is provided with a second assembly opening 521 and a guide slot 522, and the second assembly opening 521 is arranged opposite to the first assembly opening 13. Figure 8 As shown, the portion of the color strip 40 provided with multiple color zones 41 is slidably mounted in the guide slot 522, and the other portion extends to the second assembly opening 521 and is provided with a second plug-in portion 42. The first plug-in portion 31 of the color-changing key 30 passes through the first assembly opening 13 and the second assembly opening 521 in sequence to be plugged and matched with the switch 22; the third plug-in portion 32 extends to the second assembly opening 521 and is plugged and matched with the second plug-in portion 42.

[0066] It can be understood that by setting up the mounting bracket 50, and providing the guide groove 522 on the mounting bracket 50, not only it is convenient to install the color changing module 20 and the color strip 40 in the pen body 10, but also the sliding of the color strip 40 can be made more stable through the guidance of the guide groove 522, thereby avoiding the color strip 40 from shaking or getting stuck during the sliding process.

[0067] Optionally, in one embodiment, as Figure 5 As shown, a clamping portion 33 is further provided on the surface of the color-changing key 30 facing the first assembly opening 13. The clamping portion 33 is specifically a buckle. The clamping portion 33 is slidably clamped with the pen body 10 or the mounting bracket 50, and the clamping portion 33 is used to limit the color-changing key 30 from moving in a direction away from the first assembly opening 13. In this way, the color-changing key 30 can be prevented from falling off the pen body 10 during use, thereby improving the installation stability of the color-changing key 30.

[0068] It should be noted that the specific size, shape, position, etc. of the clamping portion 33 can be flexibly designed as needed, as long as the color-changing key 30 can be prevented from being separated from the pen body 10 .

[0069] Optionally, in one embodiment, please combine Figure 1 and Figure 8 The color-changing key 30 extends along the length direction of the pen body 10 , and when the color-changing key 30 is sliding, the color-changing key 30 always covers the first assembly opening 13 , which can prevent the user from seeing the interior of the smart pen 100 from the first assembly opening 13 , thereby improving the appearance of the smart pen 100 , and can also prevent foreign objects from falling into the interior of the smart pen 100 through the first assembly opening 13 , thereby improving the safety of using the smart pen 100 .

[0070] Optionally, in one embodiment, as Figure 1 As shown, the observation hole 11 is spaced apart from the color-changing key 30 along the sliding direction of the color-changing key 30 , and in the sliding direction of the color-changing key 30 , the maximum distance between the observation hole 11 and the color-changing key 30 is greater than the maximum sliding stroke of the color-changing key 30 .

[0071] Specifically, for example, the color-changing key 30 has a left limit position and a right limit position, and the viewing hole 11 is located on the right side of the color-changing key 30. In this case, the movement stroke of the color-changing key 30 between the left limit position and the right limit position is the maximum sliding stroke. When the color-changing key 30 slides to the left limit position (such as Figure 1 As shown in FIG. 1 , the distance between the color-changing key 30 and the observation hole 11 is the maximum distance. In this embodiment, by making the maximum distance between the observation hole 11 and the color-changing key 30 greater than the maximum sliding stroke of the color-changing key 30, the color-changing key 30 can still be spaced apart from the observation hole 11 when the color-changing key 30 slides to the right limit position, thereby preventing the color-changing key 30 from covering the observation hole 11 and causing the user to be unable to observe the color area 41.

[0072] Optionally, in one embodiment, a switching switch 22 is provided on the color changing module 20, and the switching switch 22 is used to switch the color gear 21, and multiple color gears 21 are arranged along the circumferential direction of the pen body 10; the color changing key 30 and the color bar 40 are respectively rotatably installed on the pen body 10, and the color changing key 30 is connected to the switching switch 22.

[0073] Specifically, taking the cylindrical pen body 10 as an example, at this time, the multiple color gears 21 on the color changing module 20 are arranged along the circumferential direction of the pen body 10, that is, the multiple color gears 21 are arranged along an arc direction. Therefore, the switching switch 22 needs to move along an arc direction to switch the color gears 21. At this time, the color changing key 30 can be installed at the end of the pen body 10 and rotatably connected to the pen body 10, and the color changing key 30 is connected to the switching switch 22, and then the user can switch the handwriting color by rotating the color changing key 30.

[0074] On the basis of the color-changing key 30 triggering the color-changing module 20 to switch the color gear 21 by rotating, the color bar 40 is also rotatably installed in the pen body 10, and the color bar 40 is connected to the color-changing key 30 and rotates with the color-changing key 30, so that the corresponding color area 41 on the color bar 40 can be rotated to the observation hole 11 for the user to observe.
