[0031] At present, the dictionary pens on the market generally have a trigger structure installed at the bottom, and the trigger structure includes an antenna, a spring, and a microswitch. When the user presses the dictionary pen against the scanned content, the antenna contracts inward into the dictionary pen to trigger the microswitch, and the dictionary pen turns on the scanning function. When the user lifts the dictionary pen, the spring resets the antenna by elastic force, and the dictionary pen turns off the scanning function. Based on this, the structure of the trigger structure is relatively complex, and the occupied space is relatively large, which limits the design and development of the dictionary pen. The homogenization of the dictionary pens on the market is serious, and the use experience is relatively single.

[0032] Accordingly, some embodiments of the present application provide a new type of dictionary pen, which can detect the pressing operation of the user on the tip of the case in real time by a pressure sensor, and can turn on or off the scanning function based on the detection data of the pressure sensor.

[0033] To describe the technical solutions according to the present application in detail, the following will be described in detail in conjunction with specific drawings and embodiments.

[0034] Embodiment 1 Referring to FIGS. 1 and 2, some embodiments of the present application provide a dictionary pen, which includes a case 10 and a pressure sensor 20. An opening 11 penetrating in the vertical direction is provided at the tip of the case 10. The case 10 has a front wall structure 12 located on the front side of the opening 11 and two side wall structures 13 respectively located on the left and right sides of the opening 11. The pressure sensor 20 is provided in the opening 11 and is attached to the front wall structure 12 or the side wall structure 13. The pressure sensor 20 is used to detect the pressing operation of the user on the tip of the case 10, and the dictionary pen can turn on or off the scanning function based on the detection data of the pressure sensor 20.

[0035] Here, it should be noted that the case 10 may have an integrally formed structure or a split connection structure, and this embodiment is not limited thereto. An aperture 11 penetrating in the vertical direction is provided at the tip of the case 10, and the pressure sensor 20 is installed inside the aperture 11. By installing it in this way, it is easier for the case 10 to protect the pressure sensor 20 from dust, water, and damage, and the performance and service life of the pressure sensor 20 can be guaranteed.

[0036] The number of pressure sensors 20 installed is at least one. When one pressure sensor 20 is provided, one pressure sensor 20 may be attached to the front wall structure 12 or the side wall structure 13. When a plurality of pressure sensors 20 are provided, the plurality of pressure sensors 20 may be respectively attached to the front wall structure 12 and / or the side wall structure 13, and this embodiment is not limited thereto.

[0037] Since the pressure sensor 20 is attached to the front wall structure 12 or the side wall structure 13, when the front wall structure 12 or the side wall structure 13 to which the pressure sensor 20 is attached receives stress and at least locally deforms, the pressure sensor 20 can identify and detect whether the user has performed a pressing operation on the tip of the case 10 by detecting the amount and change situation of the strain in the covered area.

[0038] Here, it should be further noted that a scan window is formed at the lower port of the aperture 11. The dictionary pen further includes a scan module (not shown) that is signal-connected to the pressure sensor 20. Based on the detection data of the pressure sensor 20, when it is identified and detected by the pressure sensor 20 that the user has performed a pressing operation on the tip of the case 10, the scan module turns on the scan function, scans through the scan window, and can read the scan content. Otherwise, the scan module turns off the scan function.

[0039] Accordingly, when the user grips the dictionary pen and presses the tip of the case 10 of the dictionary pen against the scan content, the scan pen according to the embodiment of the present application places the pressing force on the front wall structure 12 by the front wall structure 12, transmits the pressing force to the front wall structure 12 and the side wall structure 13, and at least a part of the front wall structure 12 or the side wall structure 13 where the pressure sensor 20 is attached can be distorted by stress. Based on this, the pressure sensor 20 can identify and detect whether the user has performed a pressing operation on the tip of the case 10 by detecting the amount of distortion and the change situation in the covered area. Based on the detection data of the pressure sensor 20, when the dictionary pen identifies and detects that the user has performed a pressing operation on the tip of the case 10 by the pressure sensor 20, the scan function can be turned on, otherwise the dictionary pen turns off the scan function.

[0040] Accordingly, compared with the conventional dictionary pen, the dictionary pen according to the embodiment of the present application can significantly simplify the number of parts and the structural complexity of the related structure for triggering the on or off of the scan function of the dictionary pen, can significantly save the occupied space of the related structure for triggering the on or off of the scan function of the dictionary pen, can provide more possibilities for the design and development of the dictionary pen, and can effectively improve the user experience of the dictionary pen.

[0041] Referring to FIGS. 1 and 2, in this embodiment, the pressure sensor 20 is attached to the side wall structure 13. The side wall structure 13 has a strain detection region 131. The pressure sensor 20 covers at least a part of the strain detection region 131, and a first stress groove 1311 is provided in the strain detection region 131.

[0042] According to the installation of this embodiment, when the user holds the dictionary pen and presses the tip of the case 10 of the dictionary pen against the scanned content, the front wall structure 12 can bear the pressing force and transmit the pressing force to the side wall structure 13. Then, based on the first stress groove 1311 installed in the strain detection area 131 of the side wall structure 13, the stress concentrates on the first stress groove 1311 and its vicinity, and the strain detection area 131 can receive the concentrated stress to generate concentrated strain on the first stress groove 1311 and its vicinity. Thereby, the pressure sensor 20 that at least covers a part of the strain detection area 131 can accurately identify and detect whether the user has performed a pressing operation on the tip of the case 10 by highly sensitively, reliably, and effectively detecting the strain amount and change situation of the covered area.

[0043] Here, in this embodiment, the parameters such as the groove depth and groove width of the first stress groove 1311 are not uniquely limited.

[0044] Referring to FIGS. 1 and 2, in this embodiment, the first stress groove 1311 is formed to extend in the vertical direction and is installed to penetrate in the vertical direction.

[0045] By forming the first stress groove 1311 to extend in the vertical direction and installing it to penetrate in the vertical direction, the extending direction of the first stress groove 1311 can be made to intersect and thus be perpendicular to the stress direction, which can relatively weaken the structural strength of the first stress groove 1311 and its vicinity in the strain detection area 131, and can ensure the structural strength of the front and rear sides of the first stress groove 1311 in the strain detection area 131. Based on this, the stress can be concentrated on the first stress groove 1311 and its vicinity, and the strain detection area 131 can receive the concentrated stress to generate concentrated compressive strain on the first stress groove 1311 and its vicinity. Furthermore, it becomes easier to realize that the pressure sensor 20 highly sensitively, reliably, and effectively detects the strain amount and change situation, and it can be realized to accurately identify and detect whether the user has performed a pressing operation on the tip of the case 10.

[0046] However, in other possible embodiments, the first stress groove 1311 may extend in other directions and / or may be installed so as not to penetrate in its extending direction and / or a plurality of first stress grooves 1311 may be installed, and the plurality of first stress grooves 1311 may be installed intersecting each other. This embodiment is not limited thereto.

[0047] Referring to FIGS. 1 and 2, in this embodiment, the side wall structure 13 is an integrally formed structure. By installing in this way, the processing of the side wall structure 13 can be facilitated and the assembly process of the side wall structure 13 can be simplified.

[0048] Referring to FIGS. 1 and 2, in this embodiment, a plurality of pressure sensors 20 are provided, and the plurality of pressure sensors 20 are respectively installed on two side wall structures 13.

[0049] According to the installation of this embodiment, when the user grips the dictionary pen and presses the tip of the case 10 of the dictionary pen against the scanned content, the front wall structure 12 can bear the pressing force and transmit the pressing force to the two side wall structures 13. Then, the plurality of pressure sensors 20 respectively installed on the two side wall structures 13 can respectively detect the amount of distortion and the change situation of the corresponding side wall structure 13, whereby the detection data of the plurality of pressure sensors 20 can be combined to accurately identify and detect whether the user has performed a pressing operation on the tip of the case 10.

[0050] Referring to FIGS. 1 and 2, in this embodiment, the pressure sensor 20 is adhered to the front wall structure 12 or the side wall structure 13. Specifically, the pressure sensor 20 may be adhered to the front wall structure 12 or the side wall structure 13 by a method including but not limited to double-sided tape 30, adhesive film, dispensing adhesive, adhesive, etc. By installing in this way, the connection convenience, connection reliability, and connection stability between the pressure sensor 20 and the front wall structure 12 or the side wall structure 13 can be guaranteed and improved.

[0051] Referring to FIGS. 1 and 2, in this embodiment, the pressure sensor 20 is a polymer material pressure sensor 20.

[0052] By adopting the above solution, the pressure sensor 20 can be provided with characteristics such as firmness, light weight, softness, flexibility, and impact resistance. The pressure sensor 20 can detect micron-level strain, and further, the use performance and detection accuracy of the pressure sensor 20 can be guaranteed and improved, and the service life of the pressure sensor 20 can be guaranteed and extended.

[0053] Of course, in other possible embodiments, the pressure sensor 20 may be a piezoresistive pressure sensor, a piezoelectric pressure sensor, a capacitive pressure sensor, or other types of sensors.

[0054] In the prior art, since the antenna is a movable member, the conventional dictionary pen cannot be effectively sealed at least by the antenna. Water and dust are likely to enter the conventional dictionary pen, which further affects the use performance and service life of the conventional dictionary pen.

[0055] In contrast, referring to FIGS. 1 and 2, in this embodiment, the dictionary pen further includes two glass screens (not shown), and the two glass screens respectively seal and cover the upper port and the lower port of the opening 11.

[0056] By adopting the above solution, the dictionary pen according to this embodiment installs the pressure sensor 20 in the opening 11, and then seals and covers the upper port and the lower port of the opening 11 with two glass screens respectively, so that the two glass screens and the case 10 jointly seal the pressure sensor 20 in the internal space. Based on this, the sealing performance, dustproof performance, and waterproof performance of the dictionary pen can be effectively guaranteed and improved, the use performance of the dictionary pen can be effectively guaranteed and improved, and the service life of the dictionary pen can be effectively guaranteed and extended.

[0057] Embodiment 2 The differences between this embodiment and Embodiment 1 are as follows.

[0058] Referring to FIG. 3, in this embodiment, the side wall structure 13 includes a side wall body 132 and a first structural member 133 that is attached inside the side wall body 132 and forms a strain detection region 131. At least a part of a first stress groove 1311 is provided in the first structural member 133.

[0059] By adopting the above solution, by separately forming the side wall body 132 and the first structural member 133 that forms the strain detection region 131, the forming of the first structural member 133 and the first stress groove 1311 can be facilitated. Further, the first structural member 133 is attached inside the side wall body 132 by means such as embedding. In this way, similarly, concentrated stress can be received in the strain detection region 131 to generate concentrated strain in the first stress groove 1311 and its vicinity, and the pressure sensor 20 can detect the strain amount and change situation of the strain detection region 131, and it can identify and detect whether "the user has performed a pressing operation on the tip of the case 10".

[0060] Embodiment 3 The differences between this embodiment and Embodiment 1 are as follows.

[0061] Referring to FIGS. 4 and 5, in this embodiment, the pressure sensor 20 is attached to the front wall structure 12. The front wall structure 12 includes a front wall body 121 and a load-bearing member 122. An attachment groove 1211 is provided on the front side of the front wall body 121, and a watermark groove 1212 is provided at the groove bottom of the attachment groove 1211. The load-bearing member 122 is attached to the attachment groove 1211, the pressure sensor 20 is attached to the rear side of the load-bearing member 122, and the pressure sensor 20 and the groove bottom of the watermark groove 1212 are installed at an interval.

[0062] Here, it should be noted that the edge of the load-bearing member 122 is supported by the groove bottom of the mounting groove 1211, and the portion corresponding to the embossing groove 1212 of the load-bearing member 122 is suspended. Based on this, the load-bearing member 122 can form a strain beam that can be stressed and generate strain.

[0063] The pressure sensor 20 is attached to the rear side of the load-bearing member 122. When the load-bearing member 122 is stressed and strained, the pressure sensor 20 can identify and detect whether the user has performed a pressing operation on the tip of the case 10 by detecting the amount and change status of the strain in the area it covers. During this period, a deformation space for deforming the load-bearing member 122 and the pressure sensor 20 can be formed in the embossing groove 1212, especially in the gap space between the pressure sensor 20 and the groove bottom of the embossing groove 1212.

[0064] Accordingly, according to the installation of this embodiment, when the user holds the dictionary pen and presses the tip of the case 10 of the dictionary pen against the scanned content, the load-bearing member 122 can bear the pressing force, be stressed, and generate strain. Based on this, the pressure sensor 20 attached to the rear side of the load-bearing member 122 can identify and detect whether the user has performed a pressing operation on the tip of the case 10 by detecting the amount and change status of the strain in the area it covers. Then, based on the detection data of the pressure sensor 20, the dictionary pen can turn on the scan function when the pressure sensor 20 identifies and detects that the user has performed a pressing operation on the tip of the case 10, otherwise, turn off the scan function.

[0065] Referring to FIGS. 4 and 5, in this embodiment, a second stress groove 1221 is provided on the rear side of the load-bearing member 122.

[0066] By installing a second stress groove 1221 on the rear side of the load-bearing member 122, the structural strength of the second stress groove 1221 of the load-bearing member 122 and its vicinity can be relatively weakened. Based on this, when the load-bearing member 122 bears a pressing force, the stress can be concentrated on the second stress groove 1221 and its vicinity, facilitating the generation of concentrated strain on the load-bearing member 122 at the second stress groove 1221 and its vicinity. Thereby, the pressure sensor 20 can accurately identify and detect whether "the user has performed a pressing operation on the tip of the case 10" by highly sensitively, reliably, and effectively detecting the strain amount and change situation in the area it covers.

[0067] Referring to FIGS. 4 and 5, in this embodiment, the second stress groove 1221 is formed to extend in the left-right direction.

[0068] By forming the second stress groove 1221 to extend in the left-right direction, the extending direction of the second stress groove 1221 can be made to intersect, and thus be perpendicular to, the stress direction. The structural strength of the second stress groove 1221 of the load-bearing member 122 and its vicinity can be relatively weakened, and the structural strength of the upper and lower both-side portions of the second stress groove 1221 of the load-bearing member 122 can be ensured. Based on this, the stress can be concentrated on the second stress groove 1221 and its vicinity, enabling the load-bearing member 122 to receive concentrated stress and generate concentrated bending strain at the second stress groove 1221 and its vicinity. Furthermore, it becomes easier to realize the pressure sensor 20 highly sensitively, reliably, and effectively detecting the strain amount and change situation, and to accurately identify and detect whether "the user has performed a pressing operation on the tip of the case 10".

[0069] Here, in this embodiment, the parameters such as the groove depth and groove width of the second stress groove 1221 are not uniquely limited.

[0070] However, in other possible embodiments, the second stress groove 1221 may be installed so as to penetrate or not penetrate in its extending direction, and / or the second stress groove 1221 may extend in other directions, and / or a plurality of second stress grooves 1221 may be installed, and the plurality of second stress grooves 1221 may be installed intersecting each other. This embodiment is not limited thereto.

[0071] Embodiment 4 The differences between this embodiment and Embodiment 1 are as follows.

[0072] Referring to FIG. 6, in this embodiment, the pressure sensor 20 is attached to the front wall structure 12. The front wall structure 12 includes a front wall main body 121, a load-bearing member 122, and a second structural member 123. An attachment groove 1211 is provided on the front side of the front wall main body 121, and a watermark groove 1212 is provided at the groove bottom of the attachment groove 1211. Both the load-bearing member 122 and the second structural member 123 are attached to the attachment groove 1211. The second structural member 123 is attached to the rear side of the load-bearing member 122, and the pressure sensor 20 is attached to the rear side of the second structural member 123. The pressure sensor 20 and the groove bottom of the watermark groove 1212 are installed at an interval.

[0073] It should be noted here that the edge of the second structural member 123 is supported by the groove bottom of the attachment groove 1211, and the portion of the second structural member 123 corresponding to the watermark groove 1212 is suspended. Based on this, the second structural member 123 can form a strain beam that can receive stress and generate strain. Here, the second structural member 123 may be a steel sheet, but is not limited thereto.

[0074] The pressure sensor 20 is attached to the rear side of the second structural member 123. When the second structural member 123 is stressed and distorted, the pressure sensor 20 can identify and detect whether the user has performed a pressing operation on the tip of the case 10 by detecting the amount of distortion and the change situation in the area it covers. During this period, in the watermark groove 1212, especially in the gap space between the pressure sensor 20 and the groove bottom of the watermark groove 1212, a deformation space for deforming the second structural member 123 and the pressure sensor 20 can be formed.

[0075] Accordingly, according to the installation of this embodiment, when the user holds the dictionary pen and presses the tip of the case 10 of the dictionary pen against the scanned content, the load-bearing member 122 can bear the pressing force and transmit the pressing force to the second structural member 123. Then, the second structural member 123 can be stressed and distorted. Based on this, the pressure sensor 20 attached to the rear side of the second structural member 123 can identify and detect whether the user has performed a pressing operation on the tip of the case 10 by detecting the amount of distortion and the change situation in the area it covers. Then, based on the detection data of the pressure sensor 20, when the dictionary pen identifies and detects that the user has performed a pressing operation on the tip of the case 10 by the pressure sensor 20, the scan function can be turned on; otherwise, the scan function can be turned off.

[0076] Referring to FIG. 6, in this embodiment, a third stress groove 124 is provided on the rear side of the second structural member 123.

[0077] By installing the third stress groove 124 on the rear side of the second structural member 123, the structural strength in the third stress groove 124 of the second structural member 123 and its vicinity can be relatively weakened. Based on this, when the second structural member 123 receives stress, the stress can be concentrated on the third stress groove 124 and its vicinity, facilitating the generation of concentrated distortion in the second structural member 123 on the third stress groove 124 and its vicinity. Thereby, the pressure sensor 20 can accurately identify and detect whether the user has performed a pressing operation on the tip of the case 10 by highly sensitively, reliably, and effectively detecting the amount of distortion and the change situation in the area it covers.

[0078] Referring to FIG. 6, in this embodiment, the third stress groove 124 is formed to extend in the left - right direction.

[0079] By forming the third stress groove 124 to extend in the left - right direction, the extending direction of the third stress groove 124 can be made to intersect, and thus be perpendicular to the stress direction. The structural strength in the third stress groove 124 of the second structural member 123 and its vicinity can be relatively weakened, and the structural strength of the upper and lower both - side portions of the third stress groove 124 of the second structural member 123 can be ensured.

[0091] Referring to FIG. 8, in the present embodiment, the fourth stress groove 1213 is formed to extend in the left-right direction.

[0092] By forming the fourth stress groove 1213 to extend in the left-right direction, the extending direction of the fourth stress groove 1213 can intersect and thus be perpendicular to the stress direction, and the structural strength at the bottom of the mounting groove 1211 in the fourth stress groove 1213 and its vicinity can be relatively weakened, and the structural strength of the upper and lower both sides of the fourth stress groove 1213 at the bottom of the mounting groove 1211 can be ensured. Based on this, the stress can be concentrated in the fourth stress groove 1213 and its vicinity, and concentrated bending strain can be generated in the fourth stress groove 1213 and its vicinity by receiving concentrated stress at the bottom of the mounting groove 1211. Furthermore, it becomes easier to realize that the pressure sensor 20 detects the strain amount and the change situation sensitively, reliably and effectively, and it can be realized to accurately identify and detect "whether the user has performed a pressing operation on the tip of the case 10".

[0093] However, in other possible embodiments, the fourth stress groove 1213 may be installed so as to penetrate or not penetrate in its extending direction, and / or the fourth stress groove 1213 may be formed to extend in other directions, and / or a plurality of fourth stress grooves 1213 may be installed, and the plurality of fourth stress grooves 1213 may be installed to intersect, and the present embodiment is not limited thereto.

[0094] Embodiment 7 Referring to FIG. 4, in the present embodiment, an arc surface 1222 is provided on the front side of the load-bearing member 122.
