[0033] In order to make the technical solutions and advantages in the embodiments of the present application clearer, the exemplary embodiments of the present application are further described in detail in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, rather than an exhaustive list of all embodiments. It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. Furthermore, in order to provide a clearer description and make it easier to understand the present application, the parts in the drawings are not drawn according to their relative sizes, and some sizes have been exaggerated compared to other related scales; irrelevant details are not fully drawn to simplify the drawings.

[0034] like Figures 1 to 10 As shown, this embodiment proposes an electronic pen, which includes a pen body 2 and a pen tip 1, wherein the pen tip 1 is arranged at the front end of the pen body 2, and a charging interface 3 is arranged at the rear end of the pen body 2, and the charging end of the charging interface 3 faces the outside of the pen body 2, and the charging interface 3 is welded on the charging board 4, and a main control board 5 is arranged inside the pen body 2, and the main control board 5 is located below the charging board 4, and electronic components are evenly distributed on the charging board 4 and the main control board 5, and the electronic components on the charging board 4 and the main control board 5 are connected through a conductive mechanism 6, and a key spring 7 is arranged at the bottom of the charging board 4, and the curved side of the key spring 7 is against the top surface of the main control board 5, and the charging board 4 can drive the key spring 7 and the main control board 5 to be squeezed under the action of external force.

[0035] Specifically, in this embodiment, the electronic pen includes two major parts: a pen tip 1 and a pen body 2. The pen tip 1 is arranged at the front end of the pen body 2, and the pen tip 1 can be fixedly connected or detachably connected to the pen body 2. The tip of the pen tip 1 can be chamfered to avoid scratching the screen of the touch device. At the same time, the pen tip 1 can also be made of wear-resistant and noise-absorbing materials. A charging interface 3 is arranged at the end of the pen body 2, and the charging end of the charging interface 3 faces the outside of the pen body 2, and the charging interface 3 is welded on the charging board 4. The charging board 4 is provided with relevant electronic components that enable the charging interface 3 to charge the battery in the pen body 2. A main control board 5 is arranged between the charging board 4 and the pen tip 1, that is, inside the pen body 2. The main control board 5 is provided with electronic components that can realize the basic functions of the electronic pen. The main control board 5 and the charging board 4 are connected by a conductive mechanism 6, so that the electronic components on the main control board 5 can be electrically connected with the electronic components on the charging board 4 to realize signal transmission. A key shrapnel 7 is arranged between the main control board 5 and the charging board 4. The key shrapnel 7 is welded on the charging board 4, and electronic components capable of realizing the functions related to the key shrapnel 7 are arranged on the charging board 4. Figure 2As shown, the key shrapnel 7 is divided into a flat side and a curved side. The flat side is welded on the charging board 4, and the curved side is against the top of the main control board 5. In this way, when the user presses the charging interface 3, the charging interface 3 is forced to drive the charging board 4, and then the curved side of the key shrapnel 7 at the bottom of the charging board 4 is squeezed with the top of the main control board 5, so that the key shrapnel 7 is forced to conduct, so as to realize the corresponding function of the key shrapnel 7.

[0036] Furthermore, the center of the top of the main control board 5 protrudes upward to form a protrusion 8 , and the top of the protrusion 8 abuts against the curved side of the key spring 7 .

[0037] Specifically, in this embodiment, in order to make the contact between the main control board 5 and the key shrapnel 7 more stable, and to enable the curved side of the key shrapnel 7 to be deformed sufficiently to make the key shrapnel 7 internally conductive when the main control board 5 and the key shrapnel 7 are squeezed, a protrusion 8 is formed on the top of the main control board 5. The protrusion 8 is integrally formed with the main control board 5. The top of the protrusion 8 can be a plane or a curved surface that fits the curved side of the key shrapnel 7. The center of the protrusion 8 should coincide with the center of the key shrapnel 7, so that the key shrapnel 7 is more evenly stressed when it is squeezed with the protrusion 8, thereby ensuring a good pressure effect. In addition, a contact portion can also be separately provided at the center position of the top of the main control board 5. The contact portion is a columnar structure, such as a cylinder, a cuboid, a cone, etc. The separate provision of the contact portion can make the diameter of the contact portion larger than the thickness of the main control board 5, so that the top of the contact portion can be more fully contacted with the curved side of the key shrapnel 7. The top of the contact portion can also be a plane or a curved surface that matches the curved surface side of the key spring 7. In addition, the center of the top of the contact portion should also coincide with the center of the key spring 7.

[0038] In addition, in this embodiment, in order to facilitate the effective and reasonable use of the space inside the pen body 2, the length direction of the main control board 5 in this embodiment is parallel to the length direction of the pen body 2, and the surface of the charging board 4 is perpendicular to the surface of the main control board 5. The main control board 5 arranged parallel to the length direction of the pen body 2 can achieve the best layout area of ​​electronic components. Only the electronic components related to the charging interface 3 and the key shrapnel 7 need to be arranged on the charging board 4. Therefore, the size of the charging board 4 is small, and only needs to be the same as or smaller than the width or diameter of the electronic pen.

[0039] In this embodiment, the conductive mechanism 6 can be an elastic conductive mechanism 6. A portion of the elastic conductive mechanism 6 is fixed on the main control board 5, and the other portion is fixed on the charging board 4, and the elastic conductive mechanism 6 can be electrically connected to the electronic components on the main control board 5 and the charging board 4. When the charging board 4 is subjected to downward pressure applied by the user to the charging interface 3, the button spring 7 at the bottom of the charging board 4 is squeezed with the main control board 5. In this process, the elastic conductive mechanism 6 arranged between the main control board 5 and the charging board 4 will also be forced to shrink. When the user removes the pressure applied to the charging interface 3, the elastic conductive mechanism 6 will apply force to the charging board 4 in the reverse direction, so that the charging board 4 rebounds to its initial position under the action of the elastic conductive mechanism 6.

[0040] Specifically, the elastic conductive mechanism 6 includes a plurality of spring probes of the same structure, and the spring probe includes a fixed portion 6-1 and a spring portion 6-2, and the fixed portion 6-1 and the spring portion 6-2 are both made of conductive materials. The fixed portion 6-1 is a columnar structure, such as a cylinder, a cuboid, a cone, etc. The side of the fixed portion 6-1 is fixed on the board surface of the main control board 5, and the length direction of the fixed portion 6-1 is parallel to the length direction of the main control board 5. The fixed portion 6-1 can be electrically connected to the electronic components on the main control board 5. The bottom of the spring portion 6-2 is fixed to the top of the fixed portion 6-1. The top of the spring portion 6-2 is connected to the board surface of the charging board 4 and is electrically connected to the electronic components on the charging board 4. An elastic material with a certain elastic coefficient, such as a spring, rubber, etc., is embedded in the spring portion 6-2. The spring portion 6-2 can be extended and retracted under the action of an external force. Therefore, when the charging plate 4 is subjected to force, the spring portion 6-2 in the spring conductive mechanism 6 will also be compressed by the force applied by the charging plate 4. When the charging plate 4 is not subjected to force, the spring conductive mechanism 6 will also rebound the charging plate 4 to its initial position due to the spring characteristics of the spring portion 6-2.

[0041] In this embodiment, the spring portion 6-2 in the spring conductive mechanism 6 can be directly welded to the surface of the charging plate 4, or can be connected to the charging plate 4 by plugging. The welding method is the most direct and effective, and the plugging method is more conducive to assembly, which can be selected according to actual conditions.

[0042] In addition, current electronic pens, including other electronic accessories, are equipped with buttons. However, after long-term use, it will be found that the button cap will shake or tilt in a static state. This is an undesirable phenomenon caused by pressing the button multiple times or for a long time. In order to avoid this situation, the present embodiment is provided with at least one pair of spring probes between the main control board 5 and the charging board 4. This embodiment is illustrated by setting two pairs of spring probes as an example. The two pairs of spring probes can be set at the top corners on both sides of the main control board 5, and can also be adjusted according to the size of the charging board 4. The two pairs of spring probes are on the same plane, so that the charging interface 3 can maintain a stable state when not subject to external force or in a static state. It will also make the charging interface 3 more evenly stressed during the rebound to the initial position, so as to enhance the user experience.

[0043] In this embodiment, the charging end of the charging interface 3 faces the outside of the pen body 2, that is, it is exposed to the outside air. When used for a long time, dust is easily accumulated inside, which will cause poor contact between the charging interface 3 and the external charger. Based on this, the present embodiment also provides a dust cap 9 at the charging interface 3. The dust cap 9 can be directly buckled on the charging end of the charging interface 3, and the user can selectively remove the dust cap 9. In addition, in order to prevent the user from losing the dust cap 9, the present embodiment can also divide the dust cap 9 into two parts: a cap body 9-1 and a connector 9-2. Fig.11 As shown. Among them, the cap body 9-1 can still be buckled or removed from the charging end of the charging interface 3, and the connector 9-2 connects the pen body 2 and the cap body 9-1. In this way, even if the user detaches the cap body 9-1 from the charging end of the charging interface 3, the dust cap 9 can still be connected to the pen body 2 as a whole and will not be lost. At the same time, some users may not be accustomed to setting a dust cap 9 on the electronic pen, or feel that the dust cap 9 is more of a hindrance when charging. In this embodiment, a hook 9-3 may be provided on the connector 9-2 of the dust cap 9, and a through hole may be provided at the corresponding position of the pen body 2. The hook 9-3 is then inserted into the through hole, and the dust cap 9 is combined with the pen body 2 through the hook 9-3. In this way, the user can decide whether to remove the dust cap 9 according to his or her preferences.

[0044] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
