[0002] Electronic pen devices such as dictionary pens, translation pens, and reading pens are portable digital tools for language queries. They use scanning technology to scan and recognize text content, and then use the device's built-in vocabulary, translation software, etc. to achieve corresponding functions such as parsing, translating, and reading of text content.
[0003] Take the dictionary pen as an example. Currently, the dictionary pens on the market generally scan the text content on the scanning surface through the scanning window set on the pen tip. In order to make the scanning process more stable, the pen tip of the dictionary pen is generally provided with a support structure. The dictionary pen uses the support structure to support the scanning surface, so that the support structure rolls or slides along the scanning surface, so that the scanning window and the scanning surface can maintain a relatively stable position during the movement of the dictionary pen relative to the scanning surface. However, the support structure currently located at the pen tip, whether rolling or sliding along the scanning surface, has a relatively small contact area with the scanning surface, so that the pressure exerted by the dictionary pen on the scanning surface is relatively large, which not only reduces the smoothness of the movement of the dictionary pen along the scanning surface, but also makes the scanning surface prone to indentations, scratches, or even damage, affecting the user experience.

DETAILED DESCRIPTION
[0043] In order to make the technical problems solved by the present invention, the technical solutions adopted and the technical effects achieved clearer, the technical solutions of the embodiments of the present invention are further described in detail below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention.
[0044] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0045] In the present invention, unless otherwise clearly specified and limited, a first feature being "above" or "below" a second feature may include that the first and second features are in direct contact, or may include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, a first feature being "above", "above" and "above" a second feature includes that the first feature is directly above and obliquely above the second feature, or simply indicates that the first feature is higher in level than the second feature. A first feature being "below", "below" and "below" a second feature includes that the first feature is directly below and obliquely below the second feature, or simply indicates that the first feature is lower in level than the second feature.
[0046] Electronic pen devices such as dictionary pens, translation pens, and reading pens are portable digital tools for language queries. They use scanning technology to scan and recognize text content, and then use the device's built-in vocabulary, translation software, etc. to achieve corresponding functions such as parsing, translating, and reading of text content.
[0047] Among them, taking the dictionary pen as an example, it can be known from the background technology that the dictionary pens currently on the market generally scan the text content located on the scanning surface 30 through the scanning window 121 set on the pen head. In order to make the scanning process more stable, the pen head of the dictionary pen is generally provided with a supporting structure. The dictionary pen uses the supporting structure to support the scanning surface 30, so that the supporting structure rolls or slides along the scanning surface 30, so that the scanning window 121 and the scanning surface 30 can maintain a relatively stable position state during the movement of the dictionary pen relative to the scanning surface 30. However, the support structure currently located at the pen head, whether it is rolling or sliding along the scanning surface 30, the contact area between the support structure and the scanning surface 30 is relatively small, so that the pressure exerted by the dictionary pen on the scanning surface 30 is relatively large, which leads to a decrease in the smoothness of the movement of the dictionary pen along the scanning surface 30, and also makes the scanning surface 30 prone to indentation, scratches or even damage, affecting the user experience. To this end, this embodiment provides the following solution.
[0048] The present invention provides a pen tip structure, which is mainly used in the above-mentioned scanning pens, electronic pen products with the function of scanning and recognizing text, such as dictionary pens, translation pens, reading pens, etc. The pen tip structure improves the above-mentioned supporting structure and optimizes the matching method between the pen tip support 10 and the supporting structure, thereby solving a series of problems in the related art, such as the scanning surface 30 is prone to indentation, scratches or even damage due to the high pressure between the electronic pen and the scanning surface 30.
[0049] Please refer to Figure 1-Figure 7 The pen tip structure provided in this embodiment includes a pen tip support 10, which is used to install and support the parts and electronic devices related to the electronic pen and the pen tip part, so that the pen tip structure can realize functions such as text scanning and recognition and sensing of the use status through the cooperation of relevant parts and electronic devices in the application of the electronic pen. Among them, the internal hollow of the pen tip support 10 forms an installation cavity 11, which is used to provide the installation position of the above-mentioned parts and electronic devices, as well as the installation position of the relevant parts of the pen tip support 10 and the electronic pen body assembly (which can also be understood as the pen tube / pen shaft part of the electronic pen device) for disassembly and assembly. Of course, the pen tip support 10 and the pen tube of the electronic pen can also be processed in an integrated manner to make the electronic pen product more integrated.
[0050] Specifically, in order to facilitate the understanding of the scheme, this embodiment takes the case where the pen tip support 10 is in an assembled relationship with the pen body assembly, and the direction in which the pen tip support 10 extends is the same as the length direction of the pen body assembly, so that the overall structure of the electronic pen is more similar to the structural form of a writing pen. Of course, this embodiment is not limited to the above scheme, and the pen tip support 10 can also be set to a structural form that is set at an angle to the pen body assembly. This embodiment is only an exemplary description that is more conducive to understanding the present scheme, and has no actual limiting effect on the scope of protection of the present invention. In this embodiment, the opposite ends of the pen tip support 10 along the first direction are respectively defined as the front end of the pen tip and the rear end for connecting to the pen body assembly, and the front end of the pen tip support 10 is provided with a scanning window 121 that communicates with the internal space of the mounting cavity 11. In the application of the electronic pen, the scanning window 121 is used to cooperate with the scanning element arranged in the installation cavity 11 to scan the text content of the scanning surface 30, and the front end of the pen tip support 10 can also be used to provide support and stability to the entire pen tip structure. The end structure serves as a structural component that provides support to the pen tip support 10 when the electronic pen is in use (during scanning the scanning surface 30), so that the electronic pen can be stably supported by the scanning surface 30 when held by the user, and finally the scanning element can move stably along the scanning surface 30 through the scanning window 121 to achieve accurate scanning.
[0051] Please continue to refer to Figure 1-Figure 2 The above-mentioned scanning window 121 is arranged close to the lower side of the pen tip support 10, so that the scanning window 121 and the front end of the pen tip support 10 are staggered. In this way, the scanning area of the pen tip structure can be located near the lower side of the pen tip support 10, so that the pen tip structure can be in a state of being inclined to the scanning surface 30 to scan the scanning surface 30, which is more in line with the human body's usage habits for pen products.
[0052] It should be noted that the lower side of the above-mentioned pen tip support 10 is the side of the pen tip structure close to the user's hand when in use (the "lower" indicated by the arrow in the figure), and conversely, the upper side of the pen tip support 10 is located on the side away from the user's hand (the "upper" indicated by the arrow in the figure). In this structural form, when the user holds the scanning pen and scans the text content of the scanning surface 30 through the scanning window 121, the end of the pen tip support 10 will be against the scanning surface 30 under the user's grip, so that the pen tip support 10 has a tendency to deform from the lower side to the upper side.
[0053] It should be noted that the scanning window 121 of the present embodiment is preferably a closed structure, that is, the scanning window 121 is located between the front end of the pen tip support 10 and has a supporting front wall 13 for the front edge of the scanning window 121, and two supporting side walls 14 are respectively located on the left and right sides of the scanning window 121 along the width direction of the pen tip support 10, and the supporting front wall 13 is used to bear the pressing force acting on the scanning surface 30 generated by the user's grip.
[0054] Illustratively, in the implementation of the above-mentioned pen tip structure, the pen tip support 10 can be processed by an integrated molding process, for example, injection molding, sheet metal, extrusion, casting, etc.; it can also be processed in parts and subsequently assembled and connected to form a whole. This embodiment does not impose specific restrictions on this.
[0055] Specifically, the pen tip support 10 is located on the support front wall 13 and is rotatably provided with a load-bearing roller 20. The load-bearing roller 20 serves as a supporting structure of the pen tip support 10. The load-bearing roller 20 at least partially protrudes from a side surface (front side surface) of the support front wall 13 that is away from the installation cavity 11. In the process of using the pen tip support 10 to scan the scanning surface 30 through the scanning window 121, the pen tip support 10 is pressed against the scanning surface 30 through the load-bearing roller 20, so that the force between the pen tip support 10 and the scanning surface 30 is transmitted by the load-bearing roller 20. The load-bearing roller 20 rotatably provided on the support front wall 13 can rotate relative to the pen tip support 10 around its rotation axis. The friction between the pen tip support 10 and the scanning surface 30 during the relative movement is reduced by rolling, thereby reducing the risk of scratching the scanning surface 30 and making the relative movement between the pen tip support 10 and the scanning surface 30 smoother.
[0056] At the same time, the load-bearing roller 20 can also guide the moving direction of the pen tip support 10 on the scanning surface 30 to a certain extent, thereby avoiding the situation where the electronic pen cannot accurately scan and identify the text content when there is a slight offset between the direction of the force applied by the user to the pen tip support 10 and the text content on the scanning surface 30. The load-bearing roller 20 can play a role in correcting and constraining to a certain extent, thereby ensuring that the pen tip support 10 can move along a straight line on the scanning surface 30.
[0057] Furthermore, the load-bearing roller 20 is extended along the direction in which the supporting front wall 13 extends. Figure 1-Figure 5As shown, in the length projection direction of the nib support 10 , the load-bearing roller 20 extends along the width direction (left-right direction) of the nib support 10 , and the axial length of the load-bearing roller 20 is greater than 1 / 2 of the width of the nib support 10 . According to the above embodiment, the pen tip support 10 can be stably supported on the scanning surface 30 through the load-bearing roller 20. The load-bearing roller 20 is rotatably arranged on the supporting front wall 13 located at the front end of the pen tip support 10. This prevents the load-bearing roller 20 from interfering with the scanning area of the scanning window 121. At the same time, the rotating connection method can effectively reduce the friction between the load-bearing roller 20 and the scanning surface 30. In addition, the load-bearing roller 20 is extended along the direction in which the supporting front wall 13 extends, which can increase the contact area between the load-bearing roller 20 and the scanning surface 30. The dictionary pen can evenly transfer the force generated by the user's grip to the scanning surface 30 through the load-bearing roller 20, reduce the pressure between the load-bearing roller 20 and the scanning surface 30, and the pressure applied by the dictionary pen to the scanning surface 30, thereby greatly reducing the probability of the pen tip structure generating indentations and scratches on the scanning surface 30, and avoiding damage to the scanning surface 30.
[0058] In this embodiment, a support front wall 13 is provided on the front side of the scanning window 121 to support the load-bearing roller 20 as a support structure. Compared with the conventional scanning pen solution in which support structures extending forward are provided on the left and right sides of the scanning window 121, the support structure of this solution has a larger contact area with the scanning surface 30. Moreover, in the conventional solution, the scanning window 121 scans and identifies the scanning surface 30 through the openings between the support structures on its left and right sides, respectively. However, in this solution, the scanning window 121 is provided on the lower side of the pen tip support 10, thereby solving the problem of blocking the scanning area due to the closed front side of the scanning window 121. In the application of the electronic pen, when the user holds the pen tip support 10, the lower side of the pen tip support 10 is located on the side close to the scanning surface 30, and the pen tip support 10 is provided at an angle to the scanning surface 30. , so that the scanning window 121 can face the scanning surface 30, and while scanning the text content of the scanning surface 30, the load-bearing roller 20 protruding on the front side of the scanning support can also be against the scanning surface 30 to support the pen head support 10, so as to increase the contact area between the load-bearing roller 20 and the scanning surface 30, solve the problem that the scanning surface 30 is prone to indentation, scratches or even damage, etc., and allow the scanning operation of the pen head support 10 to proceed normally, without affecting the original function of the electronic pen, solving the relevant technical problems mentioned in the above background technology.
[0059] In order to facilitate the understanding of the scheme, it is necessary to explain that the above-mentioned scanning surface 30 can be understood as a surface with text content printed on it, such as paper, and the scanning surface 30 medium can be a carrier that can display text or pattern content, such as a book, newspaper, product packaging, or an electronic product display screen. In this embodiment, when scanning the scanning surface 30 with an electronic pen, the user can hold the electronic pen around the pen body assembly. In this state, taking the scanning surface 30 as an example parallel to the horizontal plane, the electronic pen and the scanning surface 30 are set at an angle. The text content of the scanning surface 30 is scanned and identified by dragging the electronic pen on the scanning surface 30 and using the pen head structure to abut against the scanning surface 30 using the above method.
[0060] Please refer to Figure 1-Figure 3 The pen tip support 10 of this embodiment is a relatively flat shell structure. The area (length and width) of the lower side and the upper side of the pen tip support 10 is larger than the area of the left side and the right side of the pen tip support 10. In the scenario where the pen tip structure is used as an electronic pen, the relative position of the pen tip support 10 and the scanning surface 30 during the scanning process is determined according to the relative position of the load-bearing roller 20 and the pen tip support 10.
[0061] According to the above-mentioned embodiments, it can be understood that when the pen tip structure is used as an electronic pen, the front end of the pen tip support slides relative to the scanning surface 30 using the bearing roller 20 as a fulcrum, and the friction resistance between the bearing roller 20 and the scanning surface 30 is small, and the bearing roller 20 has a strong guiding property. On the basis of the above-mentioned structural form, in order to further avoid the situation in which the scanning track of the electronic pen is skewed due to the deviation of the setting direction of the bearing roller 20 during scanning, which easily causes scanning errors, at least the following two settings of the bearing roller 20 are provided:
[0062] 1. In the length direction of the pen tip structure, the support front wall 13 is located on the first projection plane and extends along the width direction of the pen tip support 10, and the support front wall 13 is perpendicular to the extension direction of the pen tip support 10. That is to say, on the basis of the bearing roller 20 being arranged along the extension direction of the support front wall 13, the rotation axis of the bearing roller 20 is also arranged to be perpendicular to the extension direction of the pen tip support 10. Figure 4-Figure 5 As shown, taking the extension of the pen tip support 10 along the central axis L1 as an example, the rotation axis L2 of the load-bearing roller 20 is perpendicular to the central axis L1.
[0063] 2. In the length direction of the nib structure, the support front wall 13 is located on the first projection plane and extends along the width direction of the nib support 10, and the support front wall 13 is set at an acute angle to the extension direction of the nib support 10. According to the above-mentioned setting method 1, the nib support 10 extends along the central axis direction. In setting method 2, the central axis L1 of the nib support 10 and the rotation axis L2 of the load-bearing roller 20 are set at an acute angle.
[0064] It should be understood that no matter which of the above-mentioned configuration methods of the load-bearing roller 20 is adopted, the user can scan the text content on the scanning surface 30 when the pen tip support 10 is tilted to the scanning surface 30 or perpendicular to the scanning surface 30, and by setting the relative position between the load-bearing roller 20 and the pen tip support 10, the use of the electronic pen can be made more convenient.
[0065] For example, in an embodiment in which a display screen is provided on the upper side of the electronic pen, the display screen can display the content scanned by the electronic pen while displaying detailed information of the scanned text content (such as translation content, phonetic symbols, semantic analysis, etc.) on the display screen. The above-mentioned arrangement of the force-bearing roller 20 can arrange the rotation axis of the force-bearing roller 20 to be arranged in the same plane as the upper surface of the electronic pen, so that during the scanning and recognition process, the upper side of the electronic pen is located upward or toward the user, allowing the user to observe the display screen on the upper side of the electronic pen in real time during the scanning process, thereby improving the user experience.
[0066] Please continue to refer to Figure 1 , Figure 6-Figure 7 The front end of the pen tip support 10 is provided with a scanning side plate 12, which is specifically located at the lower side of the pen tip support 10, and one end of the scanning side plate 12 is connected to the support front wall 13 to provide an opening position for the scanning window 121. In this embodiment, Figure 7 As shown, in the width direction of the nib structure, the scanning side plate 12 is located on the second projection plane and is set at an acute angle to the extension direction of the nib support 10, and the scanning side plate 12 is inclined from the rear end to the front end of the nib support 10 toward the upper side of the nib support 10, that is, the distance between the scanning side plate 12 and the upper side of the nib support 10 gradually increases from the front end to the rear end of the nib support 10. In this way, when the nib support 10 is vertical or inclined (the lower side of the nib support 10 is close to the scanning surface 30) on the scanning surface 30, the scanning side plate 12 can be in a position facing the scanning surface 30, so that the scanning element (not shown) located in the mounting cavity 11 can scan the text content of the scanning surface 30 through the scanning window 121 located on the scanning side plate 12.
[0067] The technical solution provided above is mainly to deal with the situation that interference is easily generated in the scanning window 121 when the front end of the pen tip support 10 is a closed structure with a supporting front wall 13 in this embodiment. Exemplarily, in the traditional scanning pen solution, taking the structural name of this embodiment as an example, there are support structures protruding outwards on both sides of the front end of the pen tip support 10, and the two support structures are arranged at intervals to form a hollow structure, so as to provide a free area for the scanning window 121 set on the pen tip support 10, so that the scanning element can scan and identify the text content of the scanning surface 30 through the scanning window 121 at the front end. In the present embodiment, in order to increase the contact area between the support structure and the scanning surface 30 so as to solve the problem that the scanning surface 30 is prone to indentations, scratches or even damage, a supporting front wall 13 is provided between the front end of the pen tip support 10 and the scanning window 121. Therefore, if the conventional scanning window 121 is still provided, the supporting front wall 13 will interfere with the scanning area of the electronic pen. By adopting the above-mentioned setting of the scanning side panel 12 and the tilted setting of the scanning side panel 12, the scanning window 121 located on the scanning side panel 12 can be staggered with the supporting front wall 13, thereby avoiding the problem of interference between the scanning area and the supporting front side based on the structural form of the present embodiment, and ensuring that the electronic pen can provide the scanning function normally.
[0068] On the basis of the above-mentioned embodiment, the scanning side plate 12 is provided with a deformable component in the installation cavity 11. The deformable components are specifically provided on the left and right sides of the scanning window 121. The deformable component can be provided adjacent to the above-mentioned supporting side wall 14, or the supporting side wall 14 can also be directly used as a part of the scanning side plate 12, so that the supporting side wall 14 can be used as a deformable component. Specifically, the deformable component is extended from the first end of the scanning side plate 12 to the second end of the scanning side plate 12 along the extension direction of the pen tip support 10. The deformable component is provided with a stress groove (not shown) with a notch facing the upper side of the pen tip support 10. According to the above description of this embodiment, in the application scenario of the pen tip structure as an electronic pen, when the pen tip support 10 is pressed against the scanning surface 30 through the load-bearing roller 20 at its front end, the reaction force generated by the scanning surface 30 on the load-bearing roller 20 can be transmitted to the deformable component through the supporting front wall 13, so that the deformable component has a tendency to deform from the lower side of the pen tip support 10 to the upper side.
[0069] The position where the deformation component is provided with the stress groove forms a corresponding deformation part. It should be understood that, because the stress groove is provided on one side of the deformation part, the deformation part is more prone to stress concentration than other positions of the deformation part, so that when the deformation part is under stress, other positions of the deformation part can move relatively during the process of strain of the deformation part. Exemplarily, the deformation part and the deformation part can be formed by an integrated molding process or by assembly connection after independent processing to achieve the final molding.
[0070] According to the above embodiment, the deformation component is extended along the length direction of the nib support 10, so that in addition to being able to form the left and right edges of the scanning window 121, the deformation component can also form a cantilever structure on the nib support 10, so that the deformation component can be more easily deformed in the upward direction when subjected to the force applied by the lower side of the nib support 10. At the same time, the stress groove is arranged toward the upper side of the nib support 10 through the groove, which can constrain and guide the deformation direction of the deformation component to a certain extent, so that the deformation component can be relatively accurately deformed from the lower side of the nib support 10 to the upper side.
[0071] Based on the above structural form, a pressure sensor is also provided on the deformable component. The pressure sensor is located in the installation cavity 11 and is arranged on the upper surface of at least one deformable component. In addition, the pressure sensor covers the stress groove and is used to detect the deformation amount of the deformable component.
[0072] In the above scheme, the pressure sensor is used to detect the user's pressing action on the front end of the pen tip support 10 on the scanning surface 30, and the electronic pen can turn on or off the scanning function according to the detection data of the pressure sensor. Specifically, when the user holds the electronic pen, it can be stably supported on the scanning surface 30 through the load-bearing roller 20 provided at the front end of the pen tip support 10. Because the user pushes the entire electronic pen toward the scanning surface 30, under the interaction between the scanning surface 30 and the pen tip support 10, the force transmitted to the deformation component through the front end of the pen tip support 10 can cause the deformation part to deform. That is, in the above structural form, the part of the deformation component located at the front end of the deformation part near the pen tip support 10 will deform relative to the deformation component located at the back of the deformation part near the pen tip support 10. The end part moves from the lower side to the upper side, and because the pressure sensor is arranged at a position close to the upper side of the deformation component, the force generated by the pressure between the scanning surface 30 and the pen head structure can be directly transmitted to the pressure sensor during the deformation of the deformation component. In addition, the pressure sensor is located on the stress groove, which can effectively improve the force transmission efficiency between the deformation component and the pressure sensor, thereby improving the accuracy of the pressure sensor in obtaining the deformation data of the deformation component, and finally allowing the electronic pen to accurately switch states according to the user's usage, thereby improving the user's experience.
[0073] Please refer to Figure 3-Figure 5 As a specific assembly method between the load-bearing roller 20 and the nib support 10, on the basis of the rotational cooperation between the load-bearing roller 20 and the nib support 10, the load-bearing roller 20 is prevented from occupying too much of the overall space of the nib structure, and the load-bearing roller 20 is partially embedded in the nib support 10 to achieve the above-mentioned purpose of improving the compactness of the nib structure. Specifically, a roller groove 131 is recessed on the side (front side) of the support front wall 13 away from the installation cavity 11, and the roller groove 131 is extended along the extension direction of the support front wall 13, that is, the extension direction of the roller groove 131 is determined according to the positional relationship between the extension direction of the support front wall 13 and the nib support 10, so as to accommodate part of the load-bearing roller 20. The load-bearing roller 20 is accommodated in the roller groove 131 and at least partially protrudes from the surface of the supporting front wall 13 through the notch of the roller groove 131. The roller groove 131 can protect the load-bearing roller 20 to a certain extent, and can reduce the size of the load-bearing roller 20 protruding from the surface of the supporting front wall 13, thereby ensuring that the load-bearing roller 20 can rotate while improving the compactness of the assembly between it and the pen tip support 10.
[0074] Furthermore, the groove wall of the roller groove 131 and the load-bearing roller 20 are rotatably connected via a rotating shaft assembly, and the rotating shaft assembly includes an axial hole and a rotating shaft that can be structurally adapted so that the two can be rotatably connected. The following provides several rotatable connection methods between the load-bearing roller 20 and the pen tip support 10:
[0075] 1. An axial hole is provided on the groove wall of the roller groove 131, and a rotating shaft is provided on the end of the load-bearing roller 20;
[0076] 2. A rotating shaft is convexly provided on the groove wall of the roller groove 131, and an axial hole is opened at the end of the load-bearing roller 20;
[0077] 3. An axial hole is formed at one end of the roller groove 131, and a rotating shaft is protruded at the other end. Correspondingly, a rotating shaft is protruded at one end of the load-bearing roller 20, and an axial hole is formed at the other end.
[0078] In order to allow the load-bearing roller 20 to be placed in the roller groove 131 and to form a rotational fit relationship with the groove wall of the roller groove 131, the depth of the roller groove 131 needs to be set to be greater than the radius of the load-bearing roller 20, so that when the load-bearing roller 20 is rotatably accommodated in the roller groove 131, even if a rotational fit relationship is formed between the load-bearing roller 20 and the groove wall of the roller groove 131, the groove bottom of the roller groove 131 will not interfere with the outer peripheral surface of the load-bearing roller 20, and a gap is still maintained between the two for the load-bearing roller 20 to rotate.
[0079] That is to say, on the basis of the above-mentioned embodiment, the size of the portion of the load-bearing roller 20 placed in the roller groove 131 is larger than the size of the portion of the load-bearing roller 20 protruding from the notch of the roller groove 131 to support the front wall 13. The portion of the load-bearing roller 20 that can support the pen tip support 10 is reserved, and the compactness of the load-bearing roller 20 on the pen tip support 10 is maximized.
[0080] Please continue to refer to Figure 6-Figure 7 The lower side of the support front wall 13 and the side wall of the lower side of the pen tip support 10 are transitionally connected by the arc structure 18, which reduces the probability of interference between the lower side of the pen tip support 10 and the scanning surface 30 when the pen tip support 10 is supported on the scanning surface 30 by the load-bearing roller 20. For example, when the pen tip support 10 is tilted on the scanning surface 30 and the lower side of the scanning surface 30 faces the scanning surface 30, the support front wall 13 is supported on the scanning surface 30 by the load-bearing roller 20 thereon. At this time, the part of the support front wall 13 close to the lower side of the pen tip support is closer to the scanning surface 30 than the part close to the upper side of the pen tip support. By transitioning the support front wall 13 and the lower side of the pen tip support 10 through the above-mentioned arc structure 18, the size of the lower side of the support front wall 13 can be shortened to a certain extent, thereby reducing the interference between the support front wall 13 and the scanning surface 30 and increasing the relative angle between the pen tip support 10 and the scanning surface in the use state.
[0081] At the same time, the arc structure 18 can also reduce the friction between the pen tip support 10 and the scanning surface 30. For example, when the relative angle between the pen tip support 10 and the scanning surface 30 exceeds the preset angle, that is, the load-bearing roller 20 is separated from the scanning surface 30 and the supporting front wall 13 is against the scanning surface 30, the pen tip support 10 is in contact with the scanning surface 30 through the above-mentioned arc structure 18. Even if the pen tip support 10 is still in a dragging state relative to the scanning surface 30, the arc structure 18 will not cause excessive damage to the scanning surface 30, which is beneficial to further protect the scanning surface 30.
[0082] Please continue to refer to Figure 7 In the embodiment in which the above-mentioned pen tip support 10 is provided with a scanning side plate 12, the scanning side plate 12 is transitionally connected to the supporting front wall 13 through an arc structure 18. The scanning side plate 12 is arranged in an inclined structure so that the side close to the supporting front wall 13 is at a smaller distance from the upper side of the pen tip support 10, thereby further reducing the size of the lower part of the supporting front wall 13 and expanding the use angle between the pen tip support 10 and the scanning surface 30.
[0083] Please refer to Figure 3 As a specific structural form of the pen tip support 10, in order to facilitate the installation of parts and electronic devices, the pen tip support 10 adopts a split connection structure to enclose the installation cavity 11. Specifically, the pen tip support 10 includes a pen tip shell 15 and a shell cover 16, wherein the pen tip shell 15 serves as the supporting body of the pen tip support 10. When used as an electronic pen, it is located on the lower side of the pen tip support 10 and is mainly used to provide a user's holding position and an assembly space for related parts. Here, in order to provide the above-mentioned corresponding holding position and assembly space, a scanning window 121 is opened on the pen tip shell 15, and a support front wall 13 is formed at the front end of the pen tip shell 15. An installation cavity 11 is formed in the pen tip shell 15, and the opening of the installation cavity 11 is arranged upward. The shell cover 16 is covered on the upper side of the pen tip shell 15 and is sealed with the opening of the pen tip shell 15. When the pen tip structure is used as an electronic pen, a display screen can be provided on the shell cover 16 to display the content scanned and recognized by the electronic pen.
[0084] In addition, the shell cover 16 can be installed on the nib shell 15 through the support frame 17 to facilitate the disassembly and assembly between the nib shell 15 and the shell cover 16 to a certain extent. Specifically, the support frame 17 is detachably connected to the nib shell 15 along the opening of the nib shell 15, and the support frame 17 and the nib shell 15 can be sealed by snap-fitting. A support step is provided on the other side of the support frame 17, and the shell cover 16 is covered on the support frame 17 and will be snap-fitted with the support frame 17 through the support step.
[0085] In the above-mentioned implementation mode with a deformable component and a pressure sensor, when the user holds the electronic pen, the holding force applied by the user to the electronic pen will be transmitted from the pen body assembly and the rear end of the pen tip support 10 to the front end of the pen tip support 10, and under other external force factors, when the front end of the pen tip support 10 is subjected to a force other than the scanning surface 30, the pressure sensor will detect a change in pressure data due to the corresponding strain at the front end of the pen tip support 10, and there is a certain probability of false detection. For this purpose, please refer to Figure 3-Figure 4 The pen tip support 10 is located in the installation cavity 11 and is provided with a protruding reinforcement portion 151, wherein the reinforcement portion 151 is extended along the left and right directions of the pen tip support 10, and the connection between the opposite ends of the reinforcement portion 151 along the left and right sides of the pen tip support 10 and the pen tip support 10 is located on the rear side of the scanning window 121. Specifically, the connection between the reinforcement portion 151 and the pen tip support 10 is located on the rear side of the stress groove.
[0086] Through the above-mentioned arrangement, whenever stress is transmitted from the rear end to the front end of the pen tip support 10, the force will be transmitted to the reinforcing part 151 through the lower or upper side, as well as the left and right sides of the pen tip support 10, so that when it receives external stress, it can release the stress through it and block the stress transmission, thereby solving the problem that the pen tip support 10 generates strain under the action of user holding and other external force factors, causing stress to be transmitted to the front end of the pen tip support 10, ensuring that the pressure sensor will not detect the external force generated by the user holding or other factors, ensuring the accurate state switching of the electronic pen, and improving the user experience.
[0087] This embodiment also provides a dictionary pen, which includes the above-mentioned pen body assembly, the pen body assembly is used to provide a holding position for the user to hold the dictionary pen, and includes the above-mentioned pen head structure, wherein the rear end of the pen head structure is installed and matched with the pen body assembly.
[0088] In the embodiment of the dictionary pen, a scanning element is also provided in the mounting cavity 11, and the scanning element is used to scan the scanning surface 30 through the scanning window 121. It can be understood that the above-mentioned scanning element can be a photoelectric sensor, a camera, etc. Of course, the scanning element can also be other possible components, as long as it can scan the scanning surface 30 through the scanning window 121. The embodiment of the present application does not limit this.
