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.

[0024] Parts of the load-bearing bracket that are not connected to the positioning portion form a deformation gap with the pen tip support.
[0025] As an optional implementation, the load-bearing bracket is provided with a first stress groove between the connecting portion and the supporting portion, and the deformation portion of the load-bearing bracket is formed at the position where the first stress groove is provided;

In addition, because external forces such as hand grip will not be directly transmitted to the pressure sensor through the pen head support, it reduces or even avoids the occurrence of false touches on the pressure sensor, allowing the dictionary pen to more accurately switch between different states, effectively improving the user experience.

DETAILED DESCRIPTION
[0047] 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.
[0048] 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.
[0049] 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.
[0050] 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.
[0051] 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.
[0052] 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.
[0053] Please refer to Figure 1-Figure 6 The pen tip structure of 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 the functions of 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, 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 barrel part of the electronic pen device) to achieve 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.
[0054] 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. Of course, 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 portion 12 and a supporting portion 13 that communicate with the internal space of the mounting 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 part 12 is used to cooperate with the scanning element arranged in the installation cavity 11 to scan the text content of the scanning surface 50, and the supporting part 23 serves as a structural component to provide support for the pen head support 10 when the electronic pen is in use (during the scanning surface 50), so that the electronic pen can be stably supported by the scanning surface 50 when held by the user.
[0055] It should be noted that the supporting portion 13 is arranged on one side of the scanning portion 12. Specifically, in the projection of the pen tip structure along the first direction, the projection of the supporting portion 13 and the projection of the scanning portion 12 do not overlap each other, so as to avoid interference between the scanning area of the supporting portion 13 and the scanning portion 12. Of course, the scanning area of the supporting portion 13 and the scanning portion 12 can also achieve the same technical effect if the scanning area of the supporting portion 13 and the scanning portion 12 overlaps with each other. In addition, in order to allow the supporting portion 13 to support the pen tip support 10 as a whole on the scanning surface 50 when the electronic pen is in use, in the first direction of the pen tip support 10, the distance between the supporting portion 13 and the pen tip support 10 is greater than the distance between the scanning portion 12 and the pen tip support 10, so that when the first end of the pen tip support 10 abuts against the scanning surface 50, the pen tip support 10 can abut against the scanning surface 50 through the supporting portion 13, and at this time, the scanning portion 12 should form a certain distance from the scanning surface 50 to avoid direct contact with the scanning surface 50, which may damage the structure of the scanning portion 12 or affect the scanning effect.
[0056] Please continue to refer to Figure 3-Figure 6The pen tip structure also includes a load-bearing component 20, which is located in the installation cavity 11 and connected to the pen tip support 10, and at least part of the load-bearing component 20 extends out of the pen tip support 10 through the supporting portion 13, so that the load-bearing component 20 can support the pen tip support 10 on the scanning surface 50. Furthermore, a pressure sensor 30 is also provided in the pen tip support 10 located in the installation cavity 11. It should be understood that the pressure sensor 30 is a device or apparatus that can sense pressure signals and convert pressure signals into usable output electrical signals according to certain rules. The pressure sensor 30 is installed on the load-bearing component 20 to detect the deformation of the load-bearing component 20.
[0057] According to the technical solution provided above, the electronic pen can be stably supported on the scanning surface 50 when being held by the user. Because the user pushes the entire electronic pen toward the scanning surface 50, the load-bearing component 20, as a component arranged between the scanning surface 50 and the pen head support 10, produces a certain deformation effect under the interaction between the scanning surface 50 and the pen head support 10. Because the pen head support 10 is in contact with the scanning surface 50 through the load-bearing component 20, the force generated by the pressure between the scanning surface 50 and the pen head structure can be directly transmitted to the pressure sensor 30 through the load-bearing component 20, avoiding the force being directly transmitted to the pen head support 10, causing the pen head support 10 to deform and affect the normal operation of related components such as the scanning element, and effectively improving the effect of the force being transmitted to the pressure sensor 30 on the load-bearing component 20. At the same time, the force needs to pass through the load-bearing component 20 to be transmitted to the pen head support 10, thereby reducing the influence of the deformation of the load-bearing component 20 on the pen head support 10.
[0058] In the process of using the electronic pen to scan and identify the text content on the scanning surface 50, the pressure sensor 30 can detect the pressure applied by the user to the scanning surface 50 through the load-bearing component 20, and the dictionary pen can selectively turn on or off the scanning function according to the detection data of the pressure sensor 30. Specifically, when the load-bearing component 20 is subjected to force and deformed, the pressure sensor 30 can be squeezed or stretched by the load-bearing component 20 during the deformation of the load-bearing component 20, so as to accurately judge the current state of the dictionary pen according to whether the pressure or stretching force reaches the corresponding threshold, so as to identify and detect "whether the user has pressed the pen head structure through the pen body component". In addition, because the external force such as hand holding will not be directly transmitted to the pressure sensor 30 through the pen head support 10, it can reduce or even avoid the situation of accidental touch of the pressure sensor 30, so that the dictionary pen can more accurately switch between different states and effectively improve the user experience.
[0059] In one embodiment, in order to allow the load-bearing component 20 to transmit the tensile force or extrusion force generated by deformation to the pressure sensor 30 under the action of external force, the load-bearing component 20 can also be set as a structural component extending along the first direction. In this way, the setting direction of the load-bearing component 20 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 50, the end of the load-bearing component 20 acting on the scanning surface 50 can be more easily deformed relative to the end of the load-bearing component 20 away from the scanning surface 50, thereby stretching or squeezing the pressure sensor 30. Compared with other structural forms of the load-bearing component 20, the load-bearing component 20 extending along a certain direction in this embodiment forms a cantilever structure on the pen tip support 10, so that the pressure sensor 30 can more accurately obtain the deformation data of the load-bearing component 20, thereby achieving the purpose of opening and closing the electronic pen.
[0060] In one embodiment, the pressure sensor 30 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 fixed relative to the pen tip support 10. When the load-bearing component 20 is deformed relative to the pen tip support 10, the deformed load-bearing component 20 can achieve the purpose of opening and closing the electronic pen by resisting the micro switch.
[0061] In another embodiment, the pressure sensor 30 may also be configured with a preset pressure threshold. When the tensile force or extrusion force exerted by the load-bearing component 20 on the pressure sensor 30 is greater than or equal to the above pressure threshold, the pressure sensor 30 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 component 20 is not acted upon by external force, or the tensile force or extrusion force exerted by the load-bearing component 20 on the pressure sensor 30 is less than the above pressure threshold, the pressure sensor 30 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 30 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 separately, and then connected and fixed by assembly connection to form a whole. This embodiment does not impose specific restrictions on this.
[0064] It is worth mentioning that the pressure sensor 30 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 30, the pressure sensor 30 is not limited to being provided on the load-bearing component 20, or the load-bearing component 20 is not limited to being provided with one pressure sensor 30. Multiple pressure sensors 30 respectively obtain the tensile force or extrusion force generated by deformation at the corresponding installation position, 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 scanned surface 50 can be understood as a surface with text content printed on it, such as paper, and the scanning surface 50 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 50 with the 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 50 are set at an angle. The text content of the scanning surface 50 is scanned and recognized by dragging the electronic pen on the scanning surface 50 and using the pen head structure to abut against the scanning surface 50 using the above method.
[0066] Please continue to refer to Figure 3-Figure 6 As a specific structural form of the load-bearing component 20, the load-bearing component 20 includes a connecting portion 21 and a supporting portion 23 that can achieve relative displacement under the action of a preset external force, wherein the connecting portion 21 is used to provide an installation connection position between the load-bearing component 20 and the pen tip support 10, the connecting portion 21 is located in the installation cavity 11 and is fixedly connected to the pen tip support 10, and the supporting portion 23 is used to support the pen tip structure as a whole on the scanning surface 50 during the use of the pen tip structure. Here, the first end of the supporting portion 23 is located in the installation cavity 11 and is connected to the connecting portion 21, and the second end of the supporting portion 23 extends out of the pen tip support 10 through the supporting portion 13. According to an embodiment provided above, the load-bearing component 20 is extended from one end of the connecting portion 21 toward the supporting portion 23, so that the load-bearing component 20 is located on the nib support 10 to form a force arm, so that the supporting portion 23 can more easily generate relative movement of the connecting portion 21 under the action of external force. In this embodiment, the nib support 10 is extended in a direction away from the pen shaft, and the nib support 10 and the pen shaft have the same extension direction, that is, the extension direction from the connecting portion 21 to the supporting portion 23 can be set to be the same as the first direction. Of course, the extension direction of the supporting member can also be set at an angle to the first direction. The purpose is to improve the force transmission efficiency from the supporting portion 23 to the connecting portion 21, so that the pressure sensor 30 can more accurately detect the deformation of the load-bearing component 20. Therefore, this embodiment does not specifically limit the relative extension direction between the load-bearing component 20 and the force transmission component.
[0067] Furthermore, the connection between the connecting portion 21 and the supporting portion 23 is specifically achieved through the deformation portion 22 . Under the action of external force, the load-bearing component 20 is configured so that the connecting portion 21 can move relative to the supporting portion 23 through the deformation portion 22 .
[0068] Continuing with the above embodiment, the connecting portion 21, the deforming portion 22 and the supporting portion 23 arranged in sequence can be 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 component 20, the deforming portion 22 can use but is not limited to the following structural forms:
[0069] For example, the deformable portion 22 may be configured to have a weaker structural strength than the connecting portion 21 and the supporting portion 23, so that under the action of an external force, the deformable portion 22 is more easily deformed than the connecting portion 21 and the supporting portion 23, thereby achieving the purpose of the connecting portion 21 moving relative to the connecting portion 21 through the deformation of the deformable portion 22;
[0070] For another example, the deformation portion 22 can be made of a material with lower hardness than the support portion 23 and the connecting portion 21, so that the deformation portion 22 is easier to deform than the connecting portion 21 and the support portion 23. In this way, when the support portion 23 is subjected to external force, the support portion 23 can move relative to the connecting portion 21 through the deformation of the deformation portion 22.
[0071] In this embodiment, the pressure sensor 30 is arranged along the extension direction of the load-bearing component 20 and connected to the connecting part 21 and the supporting part 23. The supporting part 23 is displaced relative to the connecting part 21, so that the pressure sensor 30 is deformed along with the deformation of the load-bearing component 20. The supporting part 23 drives the part of the pressure sensor 30 located thereon to be displaced relative to the pressure sensor 30 located on the connecting part 21, so that the pressure sensor 30 can obtain the deformation amount of the load-bearing component 20. The deformation amount of the pressure sensor 30 tends to be consistent with the deformation amount of the load-bearing component 20, which is conducive to the pressure sensor 30 to more accurately obtain the deformation data of the load-bearing component 20, thereby more accurately judging the current state of the pen head structure and achieving the purpose of opening and closing the electronic pen.
[0072] Please refer to Figure 3-Figure 6As one of the specific structural forms in the above scheme, the connection part 21, the deformation part 22 and the support part 23 of this embodiment can be configured as an integral part, and the deformation part 22 is set to have a structural strength that is weaker than the connection part 21 and the support part 23, so that it can produce stress concentration and deform under the action of external force. Specifically, a stress groove is recessed between the connection part 21 and the support part 23, and the deformation part 22 is formed at the position where the stress groove is opened. Exemplarily, taking the embodiment in which the extension direction of the load-bearing component 20 is parallel to the first direction as an example, and in order to make it easier to understand this scheme, the pen head support 10 includes a first side surface 15 and a second side surface 16 that are arranged oppositely, and the installation cavity 11 is formed between the first side surface 15 and the second side surface 16. When the user holds the electronic pen, the first side surface 15 is defined as a side away from the user's hand, and the second side surface 16 is defined as a side close to the user's hand relative to the first side surface 15. That is to say, in the process of the electronic pen scanning the scanning surface 50, the force acting on the scanning surface 50 on the load-bearing component 20 will be roughly composed of the second side surface 16 and the first side surface 15. The stress is transmitted in the direction of the side surface 16 to the first side surface 15. Therefore, the stress groove can be set at the position of the load-bearing component 20 close to the first side surface 15 and / or the second side surface 16. The above-mentioned deformation part 22 is formed at the position where the stress groove is opened in the load-bearing component 20. Due to the existence of the stress groove, the load-bearing component 20 is more likely to generate stress concentration at the position of the deformation part 22 under the action of external force, so that the support part 23 can have a tendency to displace relative to the connecting part 21 from the direction close to the first side surface 15 to the second side surface 16 under the action of external force, so that the deformation direction of the load-bearing component 20 is consistent with the force direction of the support part 23 during the use of the electronic pen, thereby ensuring a higher efficiency in the transmission of the force, and allowing the pressure sensor 30 to more accurately obtain its deformation amount under the action of the load-bearing component 20.
[0073] The pen tip structure provided by the present invention accurately defines the deformation direction of the load-bearing component 20 through the above-mentioned implementation mode. On the basis of accurately constraining the deformation direction of the load-bearing component 20, in order to achieve a better force transmission effect between the load-bearing component 20 and the pressure sensor 30, the relative position state between the load-bearing component 20 and the pressure sensor 30 during the force transmission process is made more stable. Figure 3-Figure 6 As shown, the pressure sensor 30 can be arranged on one side of the load-bearing component 20 close to the first side 15 and / or the second side 16, that is, the pressure sensor 30 is arranged on the side of the load-bearing component 20 where the deformation is the largest, so as to achieve squeezing or stretching of the pressure sensor 30, thereby accurately obtaining the response force generated by the load-bearing component 20 to the pressure sensor 30 due to the deformation.
[0074] Of course, in combination with the description of the above-mentioned other embodiments, the setting direction of the load-bearing component 20 can be set to a structural form that deviates from the first direction, as long as it is located in the installation cavity 11 and is connected and fixed to the pen tip support 10, and extends toward the supporting portion 13.
[0075] It should be pointed out that in the embodiment in which the connecting portion 21 is connected to the supporting portion 23 via the deformable portion 22, the deformable portion 22, 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 deformable portion 22, or the load-bearing component 20 as a whole, so that when the user holds the electronic pen away from the scanning surface 50, or the force applied by the load-bearing component 20 to the scanning surface 50 is small, the load-bearing component 20 can be reset, thereby reducing the tensile force or extrusion force acting on the pressure sensor 30, which is suitable for judging when the electronic pen is not in use.
[0076] Furthermore, in other embodiments, the stress groove can also be provided on the side between the first side and the second side of the load-bearing component 20, or the stress groove can be provided around the load-bearing component 20. It can be understood that only a stress groove needs to be provided on the load-bearing component 20 to form the deformation portion 22, so that the support portion 23 can more easily be deformed between the deformation portion 22 and the connecting portion 21 to achieve the purpose of the pressure sensor 30 having a higher precision detection effect.
[0077] In the implementation manner where the load-bearing component 20 is not provided with a stress groove, the deformation of the load-bearing component 20 mainly depends on the material properties. For example, when metal or rubber or other materials are used as the load-bearing component 20, the load-bearing component 20 can have the effect of deforming under different external forces according to its own material properties. Therefore, the material is selected according to the force exerted by the electronic pen on the load-bearing component 20 when in use, combined with the plastic deformation capacity of various materials.
[0078] Therefore, based on the setting of the above embodiment, when the user holds the electronic pen and presses the pen tip structure onto the scanning surface 50 through the pen body assembly, the load-bearing component 20 can bear the pressing force through the supporting part 23, and generate strain on the deformation part 22 due to the stress. Based on this, the connecting part 21 installed on the load-bearing component 20 can stably install the load-bearing component 20 on the pen tip support 10, so that the load-bearing component 20 can be deformed in a relatively stable state and form a good force transmission effect with the pressure sensor 30.
[0079] In the above scheme, by setting the deformation part 22, the strain is generated on the deformation part 22. In this way, the pressure sensor 30 is set on the deformation part 22, or along the direction of the connecting part 21, the deformation part 22 and the supporting part 23, so that the detection sensitivity of the pressure sensor 30 is effectively improved.
[0080] In addition, according to an embodiment of the present invention, by using the load-bearing component 20 as a deformation structure, the influence of pressure on the pen tip support 10 can be reduced to avoid excessive deformation of the pen tip support 10 and cause damage, which is beneficial to the maintenance of the electronic pen.
[0081] Please continue to refer to Figure 3-Figure 6 On the basis of the above-mentioned implementation mode, in order to realize the installation coordination between the load-bearing component 20 and the pen tip support 10, and to enable the load-bearing component 20 to produce effective deformation relative to the pen tip support 10 under the action of external force, the pen tip support 10 is provided with a positioning portion 14 protruding from the installation cavity 11, and the connecting portion 21 is installed on the pen tip support 10 through the positioning portion 14.
[0082] Exemplarily, a fixing component can be used to achieve an assembly connection between the load-bearing component 20 and the nib support 10. For example, the positioning portion 14 and the connecting portion 21 are connected by a fixing component to prevent the load-bearing component 20 from being separated from the nib support 10. The positioning portion 14 and the connecting portion 21 can be connected by screwing, welding, gluing, etc. In the present embodiment, the positioning portion 14 and the connecting portion 21 preferably adopt a screwing assembly method that has high stability and allows the load-bearing component 20 to be disassembled from the nib support 10.
[0083] Please continue to refer to Figure 3-Figure 6 In the above-mentioned implementation mode of threaded connection, a threaded hole 141 can be provided on the positioning portion 14, and a positioning through hole 242 that matches the threaded hole 141 can be provided on the connecting portion 21. The screw 40 can be threadedly connected with the threaded hole 141 after moving through the positioning through hole 242, so that the connecting portion 21 can be pressed against the positioning portion 14 by the screw head of the screw 40.
[0084] It can be understood that in order to improve the assembly strength between the load-bearing component 20 and the pen tip support 10, the pen tip support 10 can be provided with two or more positioning parts 14 corresponding to one load-bearing component 20, and the connecting part 21 is respectively supported by each positioning part 14 to realize the assembly connection with each positioning part 14 through multiple fixing components.
[0085] In order to enable the support part 23 to smoothly produce relative displacement with the connecting part 21 under the action of the deformation part 22, the support part 23 and the deformation part 22 both form a deformation gap with the pen tip support 10, so that the support part 23 and the deformation part 22 are located on the pen tip support 10 to form a cantilever structure, providing space for the support part 23 to displace in the installation cavity 11.
[0086] In order to achieve the purpose of enabling the supporting portion 23 to smoothly move relative to the connecting portion 21, the present embodiment also provides another solution, such as Figure 3-Figure 6 As shown, the parts of the load-bearing component 20 that are not connected to the positioning part 14 form a deformation gap with the pen tip support 10. In this embodiment, in addition to allowing the support part 23 and the deformation part 22 to be located on the pen tip support 10 to form a cantilever structure so that the support part 23 has the freedom to displace relative to the connecting part 21, the load-bearing component 20 and the pen tip support 10 are connected only through the part where the positioning part 14 contacts the connecting part 21, and the other position areas of the load-bearing component 20 and the pen tip support 10 form a structure to avoid air. In this way, when the user holds the electronic pen, the force transmitted from the pen body component to the pen tip support 10 can be effectively reduced. By reducing the contact area between the load-bearing component 20 and the pen tip support 10, the transmission of the maximum blocking force can be achieved, thereby avoiding the deformation of the pen tip support 10 due to external force, resulting in the deformation force being transmitted to the pressure sensor 30 and causing the problem of false touch, thereby ensuring that the pressure sensor 30 has a high recognition accuracy.
[0087] On the basis of the principle of the above-mentioned embodiment, the present embodiment can also realize a design of avoiding air in which the load-bearing component 20 is located on the pen tip support 10 by protruding the positioning portion 14 on the connecting portion 21 .
[0088] In the above-mentioned manner, the load-bearing component 20 is installed and cooperated with the pen tip support 10 through the connecting part 21, that is, the fixing component is arranged at one end of the deformation part 22, so that the load-bearing component 20 at the other end of the deformation part 22 has the freedom of relative displacement, so as to meet the purpose of stably assembling the load-bearing component 20 and smoothly producing deformation at the same time.
[0089] In one embodiment, the stress groove can be pre-processed on a structural member, and then the structural member is installed on the load-bearing component 20 by embedding a lamp or the like, so as to realize the forming of the deformation portion 22.
[0090] It should be noted that the stress groove can be a straight groove, a curved groove or other special-shaped grooves.
[0091] In the present embodiment, the stress groove is configured as a straight groove, and the opening direction of the stress groove is parallel to the extension direction of the load-bearing component 20. Such a configuration can concentrate stress to the greatest extent and form a larger deformation.
[0092] Please continue to refer to Figure 3-Figure 6 In an embodiment in which the load-bearing component 20 is a split structure, the load-bearing component 20 may include a load-bearing bracket 24 and a reinforcement component 25, wherein the load-bearing bracket 24 is the main component for assembling the load-bearing component 20 and the nib support 10, and is located in the mounting cavity 11 and connected to the nib support 10, and the reinforcement component 25 is used as a supporting component for the pressure sensor 30, and is arranged on the load-bearing bracket 24, wherein the reinforcement component 25 is away from the side of the load-bearing bracket 24 (the side of the load-bearing bracket 24 close to the first side 15 in this embodiment), and the side of the reinforcement component 25 close to the first side 15 is used to provide an installation position for the pressure sensor 30.
[0093] In one embodiment, in order to improve the assembly strength between the load-bearing bracket 24 and the reinforcement component 25, a positioning groove 243 for accommodating the reinforcement component 25 can be recessed on the load-bearing bracket 24. The above-mentioned stress groove can be only provided on the load-bearing bracket 24 or the reinforcement component 25, or can be formed on both the load-bearing bracket 24 and the reinforcement component 25.
[0094] Furthermore, the reinforcing component 25 and the load-bearing bracket 24 can be relatively fixed by gluing. It can be understood that the materials used to bond the reinforcing component 25 and the load-bearing bracket 24 may include but are not limited to adhesive, double-sided tape, self-adhesive tape, UV (Ultraviolet Rays) glue, AB glue (ABglue, two-component adhesive), etc.
[0095] In combination with the above-mentioned embodiment in which the load-bearing component 20 is formed with a connecting portion 21, a deforming portion 22 and a supporting portion 23, the load-bearing bracket 24 and the reinforcing component 25 are sequentially formed with a supporting portion 23, a deforming portion 22 and a connecting portion 21 from the side close to the supporting portion 13 toward the installation cavity 11.
[0096] By dividing the load-bearing component 20 into a load-bearing bracket 24 and a reinforcing component 25, this embodiment allows the pressure sensor 30 to be pre-fixed on the reinforcing component 25 during the processing and production of the pen tip structure, and then the reinforcing component 25 is installed and matched with the load-bearing bracket 24 to ensure that the pressure sensor 30 is located on the load-bearing component 20 with higher assembly accuracy. Compared with the solution in which the load-bearing bracket 24 and the reinforcing component 25 are integrally formed, the pre-installation of the pressure sensor 30 and the reinforcing component 25 can achieve higher assembly accuracy of the pressure sensor 30 on the overall structure of the load-bearing component 20, thereby allowing the pressure sensor 30 to obtain more accurate pressure data.
[0097] Please continue to refer to Figure 3-Figure 6In the embodiment in which the above-mentioned load-bearing component 20 includes a load-bearing bracket 24 and a reinforcing component 25, the nib support 10 and the load-bearing component 20 are assembled through the positioning portion 14. In this embodiment, the positioning portion 14 is protruded from the position of the nib support 10 in the mounting cavity 11, and the load-bearing component 20 is installed on the nib support 10 through the positioning portion 14 at one end of the connecting portion 21 through the load-bearing bracket 24.
[0098] In the embodiment where the load-bearing component 20 is installed and matched with the pen tip support 10 by screwing, the threaded hole 141 can also be opened on the positioning portion 14, and the positioning through hole 242 is opened on the load-bearing bracket 24, so that the screw 40 can be screwed and matched with the threaded hole 141 when passing through the positioning through hole 242.
[0099] In combination with the above-mentioned implementation method in which the load-bearing component 20 needs to form a cantilever structure on the nib support 10 , in one embodiment, the connecting portion 21 and the deformable portion 22 of the load-bearing bracket 24 both form a deformable gap with the nib support 10 .
[0100] In another embodiment, portions of the load-bearing bracket 24 that are not connected to the positioning portion 14 form a deformation gap with the pen tip support 10 .
[0101] Of course, in this embodiment, the positioning portion 14 may also be protruded on the load-bearing bracket 24 , and in this embodiment, the positioning through hole 242 is processed on the positioning portion 14 .
[0102] In combination with the stress groove scheme, taking the implementation method in which both the load-bearing bracket 24 and the reinforcement component 25 are formed with stress grooves as an example, the load-bearing bracket 24 is provided with a first stress groove 241 between its connecting portion 21 and the supporting portion 23, and the deformation portion 22 of the load-bearing bracket 24 is formed at the position where the first stress groove 241 is opened, and the reinforcement component 25 is provided with a second stress groove 251 between its connecting portion 21 and the supporting portion 23, and the deformation portion 22 of the reinforcement component 25 is formed at the position where the second stress groove 251 is opened. The first stress groove 241 and the second stress groove 251 are relatively arranged on both sides of the load-bearing component 20, that is, the first stress groove 241 is located on the side of the load-bearing component 20 close to the second side surface 16, and the second stress groove 251 is located on the first side of the load-bearing component 20 close to the first side surface 15.
[0103] like Figure 3-Figure 6As shown, when the pen tip assembly is in use, the pen tip assembly is provided with a load-bearing assembly 20 at one end thereof against the scanning surface 50, and the angle between the pen tip assembly and the scanning surface 50 may vary depending on factors such as the user's habit of holding the electronic pen. In order to allow the pen tip structure and the scanning surface 50 to be within a preset angle range, the load-bearing assembly 20 can be deformed from the second side surface 16 toward the first side surface 15 under the action of an external force on the scanning surface 50. The load-bearing assembly 20 in this embodiment is tilted from an end close to the supporting portion 13 to an end away from the supporting portion 13 in a direction away from the first side surface 15. That is to say, the distance between the end of the load-bearing assembly 20 close to the supporting portion 13 and the first side surface 15 is smaller than the distance between the end of the load-bearing assembly 20 away from the supporting portion 13 and the first side surface 15.
[0104] For example, Figure 5-Figure 6 As shown in the figure, taking the state in which the scanning surface 50 and the horizontal plane are parallel to each other as an example, when the pen tip support 10 is in a state vertical or nearly vertical to the scanning surface 50, the load-bearing component 20 is set at an angle α between the line L1 between the end away from the supporting part 13 and the end close to the supporting part 13 and the extension line of the first side surface 15, wherein 0°<α<45°.
[0105] By implementing the above scheme, when the pen tip structure is perpendicular to the scanning surface 50 (the first side 15 and / or the second side 16 are perpendicular to the scanning surface 50), the load-bearing component 20 under the action of external force still has a tendency to deform toward the first side 15.
[0106] In one embodiment, in order to facilitate the user to identify the usage direction of the electronic pen or the pen tip structure, the first side 15 is set as a plane in this embodiment. The first side 15 serves as the pen tip structure and the front of the electronic pen. It can be configured with a display screen, etc., so that after the electronic pen scans and identifies the text content, it can be displayed through the first side 15 for the user to view and identify.
[0107] As an optional implementation of the present scheme, the pressure sensor 30 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 30 for the deformation of the load-bearing component 20. 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 load-bearing components 20 made of different structural forms and materials.
[0108] 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.
[0109] Of course, in other possible implementations, the pressure sensor 30 may also be a piezoresistive pressure sensor 30, a piezoelectric pressure sensor 30, a capacitive pressure sensor 30, or other types of sensors.
[0110] Please refer to Figure 3-Figure 6 In order to enable the load-bearing component 20 to be smoothly dragged on the scanning surface 50 during the electronic pen scanning process so as to reduce the influence of the load-bearing component 20 on the scanning surface 50 (for example, the scanning surface 50 is rubbed with the load-bearing component 20 or squeezed by the load-bearing component 20, resulting in indentations, scratches or even damage), the load-bearing component 20 of this embodiment also includes a roller component 17. Specifically, the roller component 17 is rotatably arranged at one end of the support portion 23 away from the connecting portion 21, and the roller component 17 at least partially protrudes from the outside of the pen tip support 10 through the supporting portion 13.
[0111] Among them, the roller assembly 17 may include a roller body 171 and a rotating shaft 172 passing through the roller body 171 and the body of the load-bearing assembly 20. In an embodiment in which the load-bearing assembly 20 includes a load-bearing bracket 24 and a reinforcement component 25, the roller body 171 is rotatably installed on the support portion 23 of the load-bearing bracket 24 via the rotating shaft 172.
[0112] Since the roller assembly 17 is rotatably disposed on the load-bearing bracket 24 and part of the structure of the roller body 171 protrudes out of the pen tip support 10 through the supporting portion 13, when the pen tip structure is moved along the scanning surface 50, the roller body 171 can reduce the friction between the pen tip structure and the scanning surface 50 by rotating around the rotating shaft 172, thereby reducing the friction between the pen tip structure and the scanning surface 50, thereby improving the user experience of the electronic pen.
[0113] In this embodiment, the rotation axis of the rotating shaft 172 can be set to be parallel to the opening direction of the above-mentioned first stress groove 241 and the second stress groove 251, so that when the pen tip structure is located on the scanning surface 50 and moves invisibly along the rotation direction of the roller body 171, the force acting on the load-bearing bracket 24 and the reinforcement component 25 through the roller assembly 17 can cause the load-bearing assembly 20 as a whole to deform in a direction close to the first side surface 15.
[0114] Please continue to refer to the figure. In this embodiment, in order to further improve the stability of the pen tip structure when moving on the scanning surface 50, the pen tip support 10 is provided with supporting parts 13 on the opposite sides of the scanning part 12, and the above-mentioned load-bearing components 20, pressure sensors 30 and corresponding structures matching therewith are respectively provided in the installation cavity 11 corresponding to the two supporting parts 13.
[0115] 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 pen head structure is installed at one end of the pen body assembly.
[0116] 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 50 through the scanning part 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. It only needs to be able to scan the scanning surface 50 through the scanning part 12. The embodiment of the present application does not limit this.
