Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of electronic equipment, and in particular to a pen head structure and a dictionary pen. Background Art
[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. At present, in order to determine the current state, dictionary pens on the market generally have a trigger device on the pen tip, or a sensing device on the pen body to sense whether it is held by the user. When the user presses the tip of the dictionary pen on the content to be scanned, or holds the dictionary pen, the trigger device or the sensing device will be triggered, or the user's holding information will be obtained, thereby turning on the scanning function of the dictionary pen. However, regardless of whether the above-mentioned trigger device or sensing device is used, it is difficult for the dictionary pen to accurately obtain the current usage state. For example, the trigger device is easily triggered due to the deformation of the pen body when the user holds the pen body, or the force is difficult to transmit to the sensor in the triggered state, and the sensing device cannot obtain the user's holding information due to the user's wrong holding posture, etc., which makes the device prone to malfunction, ultimately affecting the user's experience.

[0016] As an optional implementation, the pen tip support is provided with a support beam in the installation cavity, and the support beam is extended along the left and right directions of the pen tip support;
[0017] The opposite ends of the support beam are respectively fixedly connected to the two opposite load-bearing side walls, and the connection between the support beam and the load-bearing side walls is located at an end of the deformation portion away from the first end of the pen tip support.
[0018] As an optional implementation, the pen tip support is further provided with opposite supporting side walls on the left and right sides of the installation cavity, and the supporting side walls are connected to the ends of the load-bearing side walls;

DETAILED DESCRIPTION
[0039] 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.
[0040] 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.
[0041] 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.
[0042] 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.
[0043] Among them, taking the dictionary pen as an example, it can be known from the background technology that in order to judge the current state, the dictionary pens currently on the market generally have a trigger device set on the pen tip, or a sensing device for sensing whether it is held by the user is set on the pen body. When the user presses the tip of the dictionary pen on the content to be scanned, or holds the dictionary pen, the trigger device or the sensing device will be triggered, or the user's holding information will be obtained, thereby turning on the scanning function of the dictionary pen. However, regardless of whether the above-mentioned trigger device or sensing device is used, it is difficult for the dictionary pen to accurately obtain the current usage state. For example, the trigger device is easily accidentally touched due to the deformation of the pen body when the user holds the pen body, or the force is difficult to transmit to the sensor in the triggered state, and the sensing device cannot obtain the user's holding information due to the user's wrong holding posture, etc., which makes the device prone to malfunction, ultimately affecting the user's experience. To this end, this embodiment provides the following solution.
[0044] The present invention provides a pen tip structure, which is mainly used in the above-mentioned 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 trigger device structure and optimizes the matching method between the pen tip support 10 and the trigger device, thereby solving a series of problems in the related art, such as the low accuracy of electronic pen products in obtaining information on the user's usage status, which leads to easy failure.
[0045] Please refer to Figure 1-Figure 7 This embodiment provides a pen tip structure including a pen tip support 10. The pen tip support 10 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 the 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, and the installation cavity 11 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.
[0046] Specifically, in order to facilitate the understanding of the scheme, the pen tip support 10 of this embodiment is set to extend along the first direction. Generally speaking, when the pen tip support 10 forms an assembly relationship with the pen body assembly, 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. However, this embodiment is not limited to the above scheme. 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 this scheme, and has no actual limiting effect on the scope of protection of the present invention. In this embodiment, the first end of the pen tip support 10 along the first direction is provided with a scanning window 12 that communicates with the internal space of the installation cavity 11, and the second end of the pen tip support 10 along the first direction is configured to cooperate with the pen body assembly. In the application of the electronic pen, the scanning window 12 is used to cooperate with the scanning element arranged in the installation cavity 11 to scan the text content of the scanning surface 40, and the first end portion of the pen tip support 10 can 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 40), so that the electronic pen can be stably supported by the scanning surface 40 when held by the user, and finally the scanning element can move stably along the scanning surface 40 through the scanning window 12 to achieve accurate scanning.
[0047] It should be noted that the scanning window 12 of the present embodiment is preferably a closed structure, that is, the opening formed by the scanning window 12 on the pen tip support 10 includes a front edge and a rear edge located at opposite ends along the length direction of the pen tip support 10. It can be understood that the front edge is located on the side of the scanning window 12 close to the first end of the pen tip support 10, and the rear edge is located on the side of the scanning window 12 close to the second end of the pen tip support 10. In this way, the portion of the pen tip support 10 located in front of the scanning window 12 can provide the above-mentioned function of supporting the pen tip structure as a whole, and also allow the first end of the pen tip support 10 and the scanning window 12 to form a staggered structure to avoid interference between the scanning area of the scanning element and the structure of the pen tip support 10 as much as possible, and the pen tip support 10 is also located on the left and right sides of the scanning window 12, respectively, and are formed with a left edge and a right edge connected to the above-mentioned front edge and rear edge. Of course, in other embodiments, the scanning window 12 near the first end of the pen tip support 10 may also be an open structure, that is, the scanning window 12 does not have the above-mentioned front edge. In this embodiment, the pen tip support 10 is located on the left and right sides of the scanning window 12 and can extend toward the first end of the pen tip support 10 to respectively extend a supporting portion 18 for providing pen tip structural support function, so as to achieve the same technical effect as above.
[0048] It can be understood from the above-mentioned embodiments that no matter which of the above-mentioned embodiments or technical solutions not mentioned in the present embodiment are adopted, the pen tip structure is supported by the body of the pen tip support 10 or the structural components arranged on the pen tip support 10 during the process of scanning the scanning surface 40 through the scanning window 12. In this way, the scanning surface 40 can directly apply the reaction force to the pen tip support 10, and transmit the force to the mounting cavity 11, thereby improving the force transmission efficiency and transmission effect.
[0049] Please continue to refer to Figure 2-Figure 4 The above-mentioned scanning window 12 is arranged close to the first side of the pen tip support 10, so that the scanning window 12 is staggered with the first direction. In this way, the scanning area of the pen tip structure can be located at the position of the pen tip support 10 close to the first side, so that the pen tip structure can be in a state of being inclined to the scanning surface 40 to scan the scanning surface 40, which is more in line with the human body's usage habits for pen products.
[0050] It should be noted that the first side of the above-mentioned nib support 10 is the side of the nib structure that is close to the user's hand when in use (it can also be understood as the lower side of the nib support 10), and conversely, the second side of the nib support 10 (it can also be understood as the upper side of the nib support 10) is located on the side away from the user's hand. In this structural form, when the user holds the scanning pen and scans the text content of the scanning surface 40 through the scanning window 12, the end of the nib support 10 will be against the scanning surface 40 under the user's grip, so that the nib support 10 has a tendency to deform from the first side to the second side.
[0051] Continuing with the above embodiment, opposite load-bearing side walls 13 are provided on the left and right sides of the scanning window 12 in the installation cavity 11, and the load-bearing side walls 13 are extended along the length direction of the pen tip support 10. According to the above description of this embodiment, the two load-bearing side walls 13 respectively close to the side of the scanning window 12 can form the above-mentioned left edge and right edge respectively, and one end of the two load-bearing side walls 13 can be used to connect and cooperate with the end structure of the pen tip support 10 that forms the front edge of the scanning window 12, or, in an embodiment where the front edge is not provided, the ends of the two load-bearing side walls 13 close to the first end of the pen tip support 10 can serve as a supporting structure that provides support function for the pen tip structure. Based on the above scheme, 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 40 through its first end, the reaction force generated by the scanning surface 40 on the pen tip support 10 can be transmitted to the load-bearing side wall 13 through the first end of the pen tip support 10, or directly act on the load-bearing side wall 13, so that the load-bearing side wall 13 has a tendency to deform from the first side of the pen tip support 10 to the second side.
[0052] Furthermore, a deformation portion 33 is formed on the load-bearing side wall 13 toward the second side of the pen tip support 10. It should be understood that the deformation portion 33 is more prone to stress concentration than other positions of the load-bearing side wall 13, so that when the load-bearing side wall 13 is under stress, other positions of the load-bearing side wall 13 can move relative to each other during the process of strain of the deformation portion 33. Exemplarily, the deformation portion 33 and the load-bearing side wall 13 can be formed by an integrated molding process or by assembly and connection after independent processing. It should be understood that no matter which of the above methods is used to achieve the molding of the load-bearing side wall 13 and the deformation portion 33, the deformation portion 33 can use but is not limited to the following structural forms:
[0053] For example, the deformation part 33 can be set to have a structural strength that is weaker than the structural strength of the main body of the load-bearing side wall 13, so that under the action of external force, the deformation part 33 on the load-bearing side wall 13 is easier to deform than other parts of the load-bearing side wall 13, so as to achieve the purpose of deformation of the load-bearing side wall 13 through the deformation part 33;
[0054] For another example, the deformation portion 33 can be made of a material with a lower hardness than the main body of the load-bearing side wall 13, so that the deformation portion 33 is easier to deform than the main body of the load-bearing side wall 13. In this way, when the load-bearing side wall 13 is under the action of external force, the load-bearing side wall 13 can realize relative movement of the pen tip support 10 through the deformation of the deformation portion 33.
[0055] According to the above embodiment, the load-bearing side wall 13 is extended along the length direction of the nib support 10, so that in addition to forming the left and right edges of the scanning window 12, the load-bearing side wall 13 can also form a cantilever structure on the nib support 10, so that the load-bearing side wall 13 can be more easily deformed toward the second side when subjected to the force applied by the first side of the nib support 10. At the same time, the deformation portion 33 is disposed toward the second side of the nib support 10, which can constrain and guide the deformation direction of the load-bearing side wall 13 to a certain extent, so that the load-bearing side wall 13 can be relatively accurately deformed from the first side of the nib support 10 toward the second side.
[0056] Based on the above structural form, a pressure sensor 20 is provided on the load-bearing side wall 13, which is located in the installation cavity 11 and is arranged on at least one load-bearing side wall 13. The pressure sensor 20 is arranged along the direction in which the load-bearing side wall 13 extends and covers the deformation part 33, and is used to detect the deformation amount of the load-bearing side wall 13.
[0057] In the above scheme, the pressure sensor 20 is used to detect the user's pressing action on the first end of the pen tip support 10 on the scanning surface 40, and the electronic pen can turn on or off the scanning function according to the detection data of the pressure sensor 20. Specifically, the electronic pen can be stably supported on the scanning surface 40 through the first end of the pen tip support 10 when held by the user. Because the user pushes the entire electronic pen toward the scanning surface 40, under the interaction between the scanning surface 40 and the pen tip support 10, the force transmitted to the load-bearing side wall 13 through the first end of the pen tip support 10 can cause the deformation portion 33 to deform. That is, in the above structural form, the portion of the load-bearing side wall 13 located at the deformation portion 33 close to the first end of the pen tip support 10 will be deformed relative to the portion of the load-bearing side wall 13 located at the deformation portion 33 away from the first end of the pen tip support 10 through the deformation portion 33. The movement from the first side to the second side, and because the pressure sensor 20 is arranged on the load-bearing side wall 13 close to the second side, the force generated by the pressure between the scanning surface 40 and the pen head structure can be directly transmitted to the pressure sensor 20 during the deformation of the load-bearing side wall 13, and the pressure sensor 20 is located on the deformation part 33, which can effectively improve the force transmission efficiency between the load-bearing side wall 13 and the pressure sensor 20, thereby improving the accuracy of the pressure sensor 20 in obtaining the deformation data of the load-bearing side wall 13, and finally allowing the electronic pen to accurately switch states according to the user's usage, thereby improving the user's usage experience.
[0058] Of course, in other embodiments, the deformation part 33 can also be arranged at a position of the load-bearing side wall 13 close to the first side of the pen tip support 10, and in this embodiment, the pressure sensor 20 is also arranged at a position of the load-bearing side wall 13 close to the first side thereof to cover the deformation part 33. In the above embodiment, when the load-bearing side wall 13 is subjected to force and is strained as a whole through the deformation part 33, the pressure sensor 20 can be subjected to the extrusion force or stretching force applied to it by the load-bearing side wall 13 and the deformation part 33 during the deformation process, thereby realizing an accurate judgment of the user's use status according to whether the extrusion force or stretching force reaches the corresponding threshold, so as to identify and detect "whether the user has pressed the pen tip structure through the pen body assembly". Furthermore, since the load-bearing side wall 13 is disposed close to the first end of the pen tip structure, the force directly transmitted to the pressure sensor 20 through the pen body assembly or the pen tip support 10 due to external factors such as hand grip can be reduced, thereby reducing or even avoiding false touches of the pressure sensor 20, allowing the electronic pen to more accurately switch between different states, effectively improving the user experience.
[0059] In one embodiment, in order to allow the load-bearing component to transmit the tensile force or extrusion force generated by the deformation under the action of the scanning surface 40 to the pressure sensor 20, the load-bearing side wall 13 can also be set as a structural component extending along the first direction. In this way, the setting direction of the load-bearing side wall 13 on the pen tip support 10 is the same as that of the pen tip support 10. When the electronic pen acts on the scanning surface 40, the end of the pen tip support 10 acting on the scanning surface 40 can more easily be strained toward the side away from the scanning surface 40 relative to the load-bearing side wall 13, so that the pressure sensor 20 can more accurately obtain the deformation data of the load-bearing component and achieve the purpose of opening and closing the electronic pen.
[0060] In one embodiment, the pressure sensor 20 can be configured as a micro switch. As described above, the main body of the micro switch is disposed in the mounting cavity 11 and is relatively fixed to the pen tip support 10. When the load-bearing side wall 13 is deformed, the micro switch can achieve the purpose of opening and closing the electronic pen by interfering with the load-bearing side wall 13 in the deformed state.
[0061] In another embodiment, the pressure sensor 20 may also be configured with a preset pressure threshold. When the tensile force or extrusion force exerted by the load-bearing side wall 13 on the pressure sensor 20 is greater than or equal to the above pressure threshold, the pressure sensor 20 may transmit a start signal to the main board set in the electronic pen to start the electronic pen and enter a scanning state. When the load-bearing side wall 13 is not acted upon by external force, or the tensile force or extrusion force exerted by the load-bearing side wall 13 on the pressure sensor 20 is less than the above pressure threshold, the pressure sensor 20 transmits a close signal to the main board in the electronic pen to keep the electronic pen in a closed state.
[0062] In the above embodiment, by providing the pressure sensor 20 to sense and identify the user's usage status, the electronic pen can be kept in the closed state without a large displacement or with only slight pressure, thereby improving the reliability of the electronic pen.
[0063] 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.
[0064] It is worth mentioning that the pressure sensor 20 provided on the pen head support 10 in this embodiment can be set to one or more. In the case where there are multiple pressure sensors 20, the pressure sensors 20 are not limited to being provided on the load-bearing side wall 13, or the load-bearing side wall 13 is not limited to being provided with one pressure sensor 20. Multiple pressure sensors 20 respectively obtain the tensile force or extrusion force generated by deformation at the corresponding installation positions, so as to more accurately determine whether the electronic pen is in use.
[0065] In order to facilitate the understanding of the scheme, it is necessary to explain that the above-mentioned scanning surface 40 can be understood as a surface with text content printed on it, such as paper, and the scanning surface 40 medium can be a carrier that can display text or pattern content, such as a book, a newspaper, a product outer packaging, or an electronic product display screen. In this embodiment, when scanning the scanning surface 40 with an electronic pen, the user can hold the pen body assembly around the first direction. In this state, taking the scanning surface parallel to the horizontal plane as an example, the electronic pen and the scanning surface 40 are set at an angle. The text content of the scanning surface 40 is scanned and recognized by dragging the electronic pen on the scanning surface 40 and using the pen head structure to abut against the scanning surface 40 using the above method.
[0066] Please continue to refer to Figure 3-Figure 7 As a specific structural form of the load-bearing side wall 13, the load-bearing side wall 13 is also formed with a first load-bearing part 31 and a second load-bearing part 32 which can realize relative displacement through the above-mentioned deformation part 33 under the action of external force, and the first load-bearing part 31 is connected to the second load-bearing part 32 through the deformation part 33; wherein, the first load-bearing part 31 is located at an end of the deformation part 33 close to the first end of the nib support 10, and the second load-bearing part 32 is located at an end of the deformation part 33 away from the first end of the nib support 10. When the first end of the nib support 10 is against the scanning surface 40, the load-bearing side wall 13 with a relatively thin structural form is easier to deform than other parts of the nib support 10, so that the first load-bearing part 31 and the second load-bearing part 32 are more easily strained through the deformation part 33 under the action of external force, so as to more efficiently transmit the force to the pressure sensor 20, so that the pressure sensor 20 can judge the current state of the nib structure more accurately. According to an embodiment provided above, the extension direction of the load-bearing side wall 13 from one end of the second load-bearing part 32 to one end of the first load-bearing part 31 is consistent with the extension direction of the pen tip support 10, so that the first load-bearing part 31 and the second load-bearing part 32 form a cantilever structure, allowing the first load-bearing part 31 to more easily generate relative movement to the second load-bearing part 32 under the action of external force.
[0067] According to the above description of the deformation part 33, specifically, following the above embodiment, the first load-bearing part 31, the deformation part 33 and the second load-bearing part 32 arranged in sequence can be processed and formed by an integrated molding process or by assembly and connection after separate processing. It should be understood that no matter which of the above methods is used to realize the molding of the load-bearing side wall 13, the deformation part 33 can use but is not limited to the following structural forms:
[0068] For example, the deformation part 33 can be set to have a weaker structural strength than the first load-bearing part 31 and the second load-bearing part 32, so that under the action of external force, the deformation part 33 is more likely to generate strain than the first load-bearing part 31 and the second load-bearing part 32, thereby achieving the purpose of the first load-bearing part 31 moving relative to the second load-bearing part 32;
[0069] For another example, the deformation part 33 can be made of a material with lower hardness than the first load-bearing part 31 and the second load-bearing part 32, so that the deformation part 33 is easier to deform than the first load-bearing part 31 and the second load-bearing part 32. In this way, when the first end of the pen tip support 10 is subjected to external force, the first load-bearing part 31 can realize relative movement with the second load-bearing part 32 through the deformation of the deformation part 33.
[0070] In this embodiment, the pressure sensor 20 is arranged along the extension direction of the load-bearing side wall 13 and connected to the first load-bearing part 31 and the second load-bearing part 32 to cover the deformation part 33. The first load-bearing part 31 is displaced relative to the second load-bearing part 32, so that the pressure sensor 20 is deformed along with the deformation of the load-bearing side wall 13. The first load-bearing part 31 drives the part of the pressure sensor 20 located thereon to be relatively displaced relative to the pressure sensor 20 located on the second load-bearing part 32, so that the pressure sensor 20 can obtain the strain of the deformation part 33. The deformation of the pressure sensor 20 tends to be consistent with the deformation of the load-bearing side wall 13, which is conducive to the pressure sensor 20 to more accurately obtain the deformation data of the load-bearing side wall 13, thereby more accurately judging the current state of the pen head structure and achieving the purpose of opening and closing the electronic pen.
[0071] Please refer to Figure 3-Figure 7 As one of the specific structural forms in the above scheme, the first load-bearing part 31, the deformation part 33 and the second load-bearing part 32 of this embodiment can be configured as an integral part, and the deformation part 33 is set to have a structural strength that is weaker than the first load-bearing part 31 and the second load-bearing part 32, so that it can generate stress concentration and strain under the action of external force.
[0072] Continuing with the above embodiment, specifically, a stress groove 34 is recessed between the first load-bearing portion 31 and the second load-bearing portion 32. In the above embodiment, the direction in which the stress groove 34 is opened can be toward the second side or the first side of the pen tip support 10, so that the load-bearing side wall 13 can be deformed between the first side and the second side. It should be noted that the above-mentioned deformation portion 33 is formed at the position where the stress groove 34 is opened on the load-bearing side wall 13. For example, taking the extension direction of the load-bearing side wall 13 to define the direction (first direction) in which the pen tip support 10 extends as an example, that is, the load-bearing side wall 13 forms a cantilever structure. On the basis of this, the stress groove 34 can be set at a position of the load-bearing side wall 13 close to the first side and / or the second side. Due to the existence of the stress groove 34, the load-bearing side wall 13 is more likely to generate stress concentration at the position of the deformation part 33 under the action of external force, so that the first load-bearing part 31 can have a tendency to displace from the first side to the second side relative to the second load-bearing part 32 under the action of external force, so that the deformation direction of the load-bearing side wall 13 is consistent with the force direction of the deformation part 33 and the pen head support 10 during the use of the electronic pen, thereby ensuring that the force transmission efficiency is higher and the pressure sensor 20 has higher detection accuracy.
[0073] It should be pointed out that in the embodiment in which the first load-bearing part 31 is connected to the second load-bearing part 32 via the deformation part 33, the deformation part 33, in addition to having the characteristic of being deformed under the action of an external force, should also have the ability to be reset when the external force is lost. For example, an elastic material, or a physical structure with elastic deformation and reset capabilities is used as the deformation part 33, or the load-bearing side wall 13 as a whole, so that when the user holds the electronic pen away from the scanning surface 40, or the force exerted by the load-bearing side wall 13 on the scanning surface 40 is small, the load-bearing side wall 13 can be reset, so that the tensile force or extrusion force acting on the pressure sensor 20 is reduced, which is suitable for judging when the electronic pen is not in use.
[0074] In one embodiment, the stress groove 34 can also be arranged on the side between the first side and the second side of the load-bearing side wall 13 (i.e., the left side and the right side of the present embodiment), or, the stress groove 34 can be arranged around the load-bearing side wall 13. It can be understood that only the stress groove 34 needs to be arranged on the load-bearing side wall 13 and the deformation portion 33 is formed, so that the first load-bearing portion 31 can be more easily deformed between the deformation portion 33 and the second load-bearing portion 32 to achieve the purpose of the pressure sensor 20 having a higher precision detection effect.
[0075] Therefore, compared with the existing electronic pens, the electronic pen provided in the embodiment of the present application can achieve efficient transmission of force when the user presses the pen head structure on the scanning surface 40. The deformation part 33 that mainly produces strain can directly squeeze or stretch the pressure sensor 20 through the load-bearing side wall 13, so that the data detected by the pressure sensor 20 is consistent with the deformation amount of the load-bearing side wall 13, and the use state of the electronic pen can be switched synchronously with the user state, thereby improving the use experience of the electronic pen.
[0076] Continuing with the embodiment in which the load-bearing side wall 13 is formed with the first load-bearing portion 31, the second load-bearing portion 32 and the deformation portion 33 as an example, independently of the embodiment in which the load-bearing side wall 13 is provided with the stress groove 34, in this embodiment, please refer to Figure 3-Figure 7 A positioning groove 131 is provided on the load-bearing side wall 13, and a first groove 132 and a second groove 133 which are both connected to the mounting cavity 11 are respectively formed on the adjacent two sides of the positioning groove 131, thereby weakening the structural strength of part of the load-bearing side wall 13 and making it easier for the load-bearing side wall 13 to deform toward the second side. Specifically, the first groove 132 is arranged close to the second side of the pen tip support 10, and the second groove 133 is arranged on the side of the positioning groove 131 close to the mounting cavity 11. Correspondingly, a reinforcing component 30 is embedded in the positioning groove 131, and a first load-bearing portion 31, a deformation portion 33 and a second load-bearing portion 32 are formed on the reinforcing component 30 in sequence, and the pressure sensor 20 is arranged on the reinforcing component 30.
[0077] Furthermore, the reinforcing component 30 and the positioning groove 131 can be relatively fixed by gluing. It can be understood that the material used to bond the reinforcing component 30 and the positioning groove 131 may include but is not limited to adhesive, double-sided tape, self-adhesive tape, UV (Ultraviolet Rays) glue, AB glue (ABglue, two-component adhesive), etc.
[0078] By setting the load-bearing side wall 13 separately, this embodiment allows the pressure sensor 20 to be pre-fixed on the reinforcing component 30 during the processing and production of the pen tip structure, and then the reinforcing component 30 is installed and matched with the load-bearing side wall 13 through the positioning groove 131 to ensure that the pressure sensor 20 is located on the load-bearing side wall 13 with higher assembly accuracy. Compared with the one-piece load-bearing side wall 13 solution, the pre-installation of the pressure sensor 20 and the reinforcing component 30 can achieve higher assembly accuracy of the pressure sensor 20 on the overall structure of the load-bearing side wall 13, thereby allowing the pressure sensor 20 to obtain more accurate pressure data.
[0079] In addition, on the basis that the load-bearing side wall 13 is provided with a positioning groove 131, the reinforcing component 30 can also play a certain supporting role for the load-bearing side wall 13, while ensuring that the side wall can be more easily strained through the deformation portion 33 on the reinforcing component 30, avoiding the positioning groove 131 from being damaged due to excessive strain.
[0080] It should be understood that in the above-mentioned scheme where the first load-bearing portion 31, the deformation portion 33 and the second load-bearing portion 32 are formed on the reinforcement component 30, the load-bearing side wall 13 may also be provided with a deformation portion 33 corresponding to the deformation portion 33 on the reinforcement component 30. At this time, it can be understood that the first load-bearing portion 31 and the second load-bearing portion 32 of the load-bearing side wall 13 are formed at the opposite ends of the deformation portion 33 of the load-bearing side wall 13.
[0081] In the above scheme, specifically, the first notch 132 is arranged near the first side of the pen tip support 10, and the second notch 133 is arranged on the side of the positioning groove 131 near the installation cavity 11, that is, the positioning groove 131 can provide space for the reinforcement component 30 and the load-bearing side wall 13 to be assembled at different positions, so that after the pressure sensor 20 and the reinforcement component 30 form a relatively accurate fit, the reinforcement component 30 can be quickly installed and matched with the load-bearing side wall 13, thereby improving the efficiency of the disassembly and assembly of the pen tip structure. It can also be understood that since the structural volume of the reinforcement component 30 is smaller than that of the load-bearing side wall 13, the space provided on the surface of the reinforcement component 30 for the installation of the pressure sensor 20 can provide the user with a more accurate limiting area. Compared with the load-bearing side wall 13 with a larger structural size, it is obvious that installing the pressure sensor 20 on the reinforcement component 30 is simpler and more accurate than installing it on the load-bearing side wall 13.
[0082] In the above-mentioned embodiment combined with the scheme of the stress groove 34, a stress groove 34 is recessed between the first load-bearing part 31 and the second load-bearing part 32, and a deformation part 33 is formed at a position of the reinforcement component 30 corresponding to the stress groove 34. Of course, this scheme does not exclude the above-mentioned embodiment in which a stress groove 34 is recessed on the load-bearing side wall 13 to form a deformation part 33, a first load-bearing part 31 and a second load-bearing part 32 on the load-bearing side wall 13.
[0083] It is understandable that 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 second end of the pen tip support 10 to the first end of the pen tip support 10, and under other external factors, when the first end of the pen tip support 10 is subjected to a force other than the scanning surface 40, the pressure sensor 20 will detect a change in pressure data due to the corresponding strain on the first end of the pen tip support 10, and there is a certain probability of misjudgment. For this purpose, please refer to Figure 3-Figure 7The pen tip support 10 is located in the installation cavity 11 and is provided with a support beam 14. The support beam 14 is extended along the left and right directions of the pen tip support 10. The opposite ends of the support beam 14 are respectively fixedly connected to the two opposite load-bearing side walls 13, and the connection between the support beam 14 and the load-bearing side walls 13 is located at the end of the deformation portion 33 away from the first end of the pen tip support 10.
[0084] Through the above-mentioned arrangement, whenever stress is transmitted from the second end of the pen tip support 10 to the first end, the force will be transmitted to the support beam 14 through the first side or the second side, as well as the left and right sides of the pen tip support 10. One side of the support beam 14 is connected to the first side or the second side of the pen tip support 10, so that the other side of the support beam 14 is in a relatively free suspended state, so that when it receives external stress, it can release the stress through its suspended side, blocking the stress transmission, solving the problem that the pen tip support 10 generates strain under the action of user holding and other external forces, causing stress to be transmitted to the first end of the pen tip support 10, ensuring that the pressure sensor 20 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.
[0085] In an embodiment in which a positioning groove 131 is provided on the load-bearing side wall 13, the opposite ends of the support beam 14 are respectively connected to the ends of the positioning groove 131 which are respectively arranged away from the first end of the pen tip support 10. According to the above, by arranging the support beam 14 between the deformation part 33 and the second end of the pen tip support 10, the stress transmitted from the second end of the pen tip support 10 to the first end is not transmitted to the deformation part 33 but is absorbed and released by the support beam 14, thereby avoiding the stress from being strained when passing through the deformation part 33 due to the easier generation of stress concentration in the deformation part 33, thereby affecting the detection accuracy of the pressure sensor 20.
[0086] Please continue to refer to Figure 3 Since the support beam 14 is placed horizontally inside the installation cavity 11, it will have a certain impact on the installation of components and electronic devices inside the pen tip support 10. In order to minimize the interference of the support beam 14 on related components, a avoidance groove 141 is recessed in the middle of the support beam 14 to provide a connection line or some components to pass from one side of the support beam 14 to the other side.
[0087] Please refer to Figure 1-Figure 2 , Figure 6The pen tip support 10 of this embodiment is a relatively flat shell structure. The area (length and width) of the first side and the second 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 order to further reduce the influence of the strain of the overall structure of the pen tip support 10 on the pressure sensor 20, this embodiment is an embodiment that can be independent of the above-mentioned support beam 14, or can be used in combination with the above-mentioned support beam 14. The pen tip support 10 is located on the left and right sides of the installation cavity 11 and is also provided with relative supporting side walls 15. The supporting side walls 15 are connected to the end of the load-bearing side wall 13. The two supporting side walls 15, the load-bearing side walls 13 and the first side and the second side of the pen tip support 10 enclose the above-mentioned installation cavity 11. The side wall of the first side of the pen tip support 10 and the side wall of the second side of the pen tip support 10 are connected to the supporting side wall 15 and the load-bearing side wall 13 in sequence in the length direction of the pen tip support 10.
[0088] Furthermore, grooves 151 extending along their respective length directions are respectively formed on the surfaces of the two supporting side walls 15 on the opposite sides, and reinforcing ribs 152 are convexly formed on the supporting side walls 15 between the grooves 151 and the first side of the nib support 10, and between the grooves 151 and the second side of the nib support 10. The above structure can effectively strengthen the structural strength of the left and right sides of the nib support 10. On the basis that the structural form of the left and right sides of the nib support 10 is relatively weak, by strengthening the structural strength of the supporting side walls 15, the deformation of the nib support 10 under the action of external force can be reduced as much as possible, thereby limiting the stress transmitted from the second end of the nib support 10 to the first end to a certain extent.
[0089] Please continue to refer to Figure 3-Figure 7 In the above-mentioned embodiment in which a support beam 14 is provided, the support beam 14 is located at one end of the support side wall 15 close to the scanning window 12. The structural form in which the support beam 14 and the groove 151 and the reinforcing rib 152 on the support side wall 15 cooperate with each other can further enhance the structural strength of the pen tip support 10. The support side wall 15 provided with the groove 151 and the reinforcing rib 152 has a relatively stable structural form, thereby further avoiding the deformation of the first side and the second side of the pen tip support 10 which are relatively large in size. The existence of the support beam 14 can buffer and release the stress generated by the pen tip support 10 when it is slightly strained, so as to achieve the purpose of improving the stability of the electronic pen and meet the user's sensitivity requirements for switching the use status of the electronic pen.
[0090] Please refer to Figure 3-Figure 7In the use state of the pen tip assembly, the first end of the pen tip support 10 is against the scanning surface 40, and the angle between the pen tip support 10 and the scanning surface 40 may vary depending on factors such as the user's habit of holding the electronic pen. In order to make the pen tip support 10 and the scanning surface 40 within a preset angle range so that the pen tip structure can effectively scan the scanning surface 40 through the scanning window 12, in this embodiment, the first side and the second side surface of the pen tip support 10 are respectively formed with a first surface 16 and a second surface 17 that are arranged opposite to each other. The first end of the pen tip support 10 can be deformed from the first surface 16 to the second surface 17 under the external force of the scanning surface 40. The pressure sensor 20 in this embodiment It is inclined from an end close to the first end of the nib support 10 to an end away from the first end of the nib support 10 in a direction away from the second side. That is to say, in an embodiment in which the pressure sensor 20 is supported and installed by the load-bearing side wall 13, the inclination angle of the surface of the load-bearing side wall 13 used to support the pressure sensor 20 relative to the second surface 17 of the nib support 10 is also the same as that of the pressure sensor 20. Of course, here it refers to the normal state of the load-bearing side wall 13 when it is not subjected to external force. That is to say, under the support of the load-bearing side wall 13, the distance between the end of the pressure sensor 20 close to the first end of the nib support 10 and the first side surface is smaller than the distance between the end of the pressure sensor 20 away from the first end of the nib support 10 and the first side surface.
[0091] For example, Figure 3-Figure 7 As shown in the figure, taking the state in which the scanning surface 40 and the horizontal plane are parallel to each other as an example, when the pen tip support 10 is in a state vertical or tending to be perpendicular to the scanning surface 40 (the second surface 17 and the scanning surface 40 are perpendicular to each other), the pressure sensor 20 and the load-bearing side wall 13 for supporting the pressure sensor 20 are set at an angle α between the line L1 between the end away from the first end of the pen tip support 10 and the end close to the first end of the pen tip support 10 and the extension line of the second surface 17, wherein 0°<α<45°.
[0092] By implementing the above solution, when the pen tip structure is perpendicular to the scanning surface 40 (the second surface 17 is perpendicular to the scanning surface 40), the load-bearing side wall 13 under the action of external force still has a tendency to deform from the first surface 16 to the second surface 17.
[0093] In one embodiment, in order to facilitate the user to identify the usage direction of the electronic pen or the pen tip structure, the second surface 17 is set as a plane in this embodiment, and the second side surface serves as the pen tip structure and the front side of the electronic pen. It can be configured by setting a display screen, etc., so that the electronic pen can display the text content through the second side surface after scanning and identifying the text content, so as to facilitate the user's viewing and identification.
[0094] Please refer to Figure 3-Figure 7 In order to enable the pen tip support 10 to be smoothly dragged on the scanning surface 40 during the electronic pen scanning process and to reduce the influence of the pen tip support 10 on the scanning surface 40 (for example, the scanning surface 40 may be indented, scratched or even damaged due to friction or squeezing with the pen tip support 10), a supporting portion 18 is further provided at one end of the pen tip support 10 close to the scanning window 12. Specifically, the supporting portion 18 is protruding from the surface of the pen tip support 10 so that the supporting portion 18 can support the pen tip support 10 on the scanning surface 40. In one embodiment, in order to allow the pen tip support 10 to be placed on the scanning surface 40 more stably, two or more supporting parts 18 may be provided on the pen tip support, and the part of the supporting part 18 that is used to contact the scanning surface 40 is in an arc-shaped structure to reduce the friction between the supporting part 18 and the scanning surface 40. The multiple supporting parts 18 are arranged at intervals on the pen tip support 10, so that the scanning surface 40 exerts a reaction force on the supporting part 18 through the supporting part 18 acting on the scanning surface 40, and the reaction force is transmitted to the pen tip support 10, generating strain at the position of the deformation part 33 where stress concentration is more likely to occur. In another embodiment, in order to improve the stability of the pen tip support 10 on the scanning surface 40, the supporting part 18 can be extended along the left and right direction of the pen tip support 10 based on the first end of the pen tip support 10.
[0095] Furthermore, the support portion can be configured as a plate and the plates are parallel to each other, so that the sliding direction of the pen tip support 10 on the scanning surface 40 can be constrained by the supporting portion 18 of the plate structure, and the sliding process can be smoother.
[0096] As an optional implementation of the present scheme, the pressure sensor 20 is a resistance strain gauge. It should be understood that the resistance strain gauge has the characteristics of small size, light weight, and easy installation, which is conducive to the application in the electronic pen. In addition, the detection sensitivity and accuracy of the resistance strain gauge are relatively high, which can effectively improve the detection accuracy of the pressure sensor 20 for the deformation of the load-bearing side wall 13. At the same time, the resistance strain gauge can also measure the strain of components with large stress gradients, so as to meet the application requirements of the load-bearing side walls 13 made of different structural forms and materials.
[0097] In addition, the measurement results of the resistance strain gauge can also be digitized and computer processed, so that it can be directly connected to the main board of the electronic pen, so that the control unit on the main board can switch the electronic pen between different states according to its measurement data.
[0098] Of course, in other possible implementations, the pressure sensor 20 may also be a piezoresistive pressure sensor 20, a piezoelectric pressure sensor 20, a capacitive pressure sensor 20, or other types of sensors.
[0099] 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 second end of the pen head structure is installed and cooperated with the pen body assembly.
[0100] 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 40 through the scanning window 12. 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 40 through the scanning window 12. The embodiment of the present application does not limit this.
