[0054] In order to make the purpose, technical scheme and advantages of the present application more clear, the technical scheme of the present application will be described clearly and completely below in combination with the drawings in the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0055] The scanning pen of the present application will be described below in combination with Figures 1-19 The scanning pen of the present application will be described below in combination with

[0056] As shown in Figure 1 and Figure 2 The present embodiment provides a scanning pen 1, which comprises a pen shell 11, a trigger assembly 12, a pressure sensing assembly 13 and a scanning assembly 14. The pen shell 11 has a containing cavity and a guide hole communicating with the containing cavity. The trigger assembly 12 comprises a contact leg 121, which is arranged in the guide hole, and the first end of the contact leg 121 is exposed from the guide hole. The pressure sensing assembly 13 is arranged in the containing cavity, and the second end of the contact leg 121 abuts against the pressure sensing assembly 13. The scanning assembly 14 is arranged in the pen shell 11, and the scanning assembly 14 and the pressure sensing assembly 13 are electrically connected. Wherein, under the condition that the contact leg 121 is pressed on the surface of the medium to be scanned, the contact leg 121 is pressed on the pressure sensing assembly 13, and the pressure sensing assembly 13 is triggered to start the scanning assembly 14.

[0057] The pen shell 11 of the embodiment is used to mount other components of the scanning pen 1, wherein the scanning end of the pen shell 11 is provided with a guide hole, and it can be understood that the scanning end is the end of the scanning pen 1 used for aligning the medium to be scanned during scanning, and the guide hole is used to set the contact foot 121 of the trigger assembly 12. The guide hole can be used to limit the position and movement direction of the contact foot 121, and the hole wall of the guide hole can be as close as possible to the side wall of the contact foot 121. The first end of the contact foot 121 is exposed to the scanning end of the scanning pen 1 through the hole of the guide hole, so as to press the surface of the medium to be scanned during scanning.

[0058] The pen shell 11 is also provided with a containing cavity in communication with the guide hole, and the containing cavity is used to mount the pressure sensing assembly 13. It can be understood that other components of the scanning pen 1 can also be mounted in the containing cavity, such as the scanning assembly 14 and other electronic elements, circuits, etc., which are not limited in the present application. The second end of the contact foot 121 extends into the containing cavity and abuts against the pressure sensing assembly 13, and the pressure sensing assembly 13 is connected with the scanning assembly 14. The scanning assembly 14 is mainly used for scanning the medium to be scanned, and the pressure sensing assembly 13 is used to cooperate with the contact foot 121 to start the scanning assembly 14 when scanning is needed.

[0059] Specifically, the pressure sensing assembly 13 is configured to send a start signal to the scanning assembly 14 only when the pressure received by the pressure sensing assembly 13 exceeds a set threshold value, so as to make the scanning assembly 14 start and scan. In the case that the scanning end is not abutted against the medium to be scanned, the first end of the contact foot 121 is not extruded, and the second end of the contact foot 121 does not generate pressure to the pressure sensing assembly 13 or the pressure to the pressure sensing assembly 13 is smaller and does not exceed the set threshold value, so the scanning assembly 14 is closed to reduce power consumption. In the case that the scanning end is abutted against the medium to be scanned, the first end of the contact foot 121 is not extruded by the surface of the medium to be scanned, the contact foot 121 extrudes the pressure sensing assembly 13, the pressure received by the pressure sensing assembly 13 exceeds the set threshold value, a start signal is sent to the scanning assembly 14, and the scanning assembly 14 starts and scans.

[0060] It can be understood that by reasonably setting the structure of the guide hole, the relative position of the contact foot 121 and the pressure sensing assembly 13, and the set threshold value of the pressure received by the pressure sensing assembly 13 when sending the start signal, the contact foot 121 can trigger the pressure sensing assembly 13 and the scanning assembly 14 only in the case that the contact foot 121 generates slight displacement after being pressed by the medium to be scanned. This design is beneficial to reducing the structural size of the contact foot 121 exposed outside the guide hole, so as to make the integrity of the scanning end of the scanning pen 1 better.

[0061] The utility model discloses a scanning pen 1, through setting up the guide hole at the scanning end of the pen shell 11, the guide hole is used for setting up the contact foot 121, and setting up the accommodating cavity that communicates with the guide hole to accommodate the pressure sensing component 13, and make the first end of contact foot 121 expose outside the guide hole to abut the medium to be scanned when scanning, the second end of contact foot 121 abuts in the pressure sensing component 13, to produce pressure to the pressure sensing component 13, and the pressure sensing component 13 sends the start signal to scanning component 14 after the pressure reaches the set threshold value, makes scanning component 14 start and scans. As can be known from the above, the guide hole of the utility model can be used for guiding and limiting contact foot 121, the structure of the guide hole can as far as possible conform to contact foot 121, makes the structure of guide hole and contact foot 121 more compact, and the integrity is better from the appearance, simultaneously, through the structure and relative position of the reasonable setting of guide hole, contact foot 121 and pressure sensing component 13 and the set threshold value of pressure sensing component 13, can reduce the moving distance of contact foot 121 relative to the initial state when pressure sensing component 13 is triggered as far as possible, is favorable to reducing the structure size of contact foot 121 that exposes outside the guide hole, further improves the integrity of the scanning end of scanning pen 1, effectively solves the defect that the scanning end of the scanning pen in the prior art leads to the poor integrity of the whole scanning end for setting up the trigger structure of scanning device.

[0062] It can be understood that, in some embodiments, by reasonably setting the structure of the guide hole and contact foot 121 and the relative position of the pressure sensing component 13 and the guide hole, the contact foot 121 can be pressed against the pressure sensing component 13 without contacting the medium to be scanned, so that the contact foot 121 and the pressure sensing component 13 have a certain initial pressure, thereby avoiding the contact foot 121 moving away from the pressure sensing component 13 during long-term use, affecting the sensitivity of the trigger component 12 and the pressure sensing component 13.

[0063] Specifically, in some embodiments, as shown in Figure 2 , Figures 8-12 The pressure sensing component 13 includes a strain gauge 131 and a signal sending unit 132. The second end of the contact foot 121 abuts against the strain gauge 131. The signal sending unit 132 is electrically connected to the strain gauge 131 and the scanning component 14, respectively. The strain gauge 131 is configured to feed back a pressure signal to the signal sending unit 132. The signal sending unit 132 is configured to send a signal to the scanning component 14 to start the scanning component 14 according to the pressure signal fed back by the strain gauge 131.

[0064] In the embodiment, the second end of the contact foot 121 abuts against the strain gauge 131. When the contact foot 121 is pressed by the medium to be scanned, the strain gauge 131 can detect the pressure of the contact foot 121 on itself and generate a corresponding pressure signal under the action of the pressure. The signal sending unit 132 sends a start signal to the scanning component 14 when detecting a preset pressure signal, so that the scanning component 14 starts and scans.

[0065] As shown in Figure 2 , Figure 10 , Figure 11 and Figure 12 , the strain gauge 131 includes a steel sheet and a flexible circuit board, the flexible circuit board and the steel sheet are bonded together, the bonding position of the flexible circuit board and the steel sheet is printed with ink, the flexible circuit board is provided with a detection circuit and a signal sending unit 132, the ink can be used as a resistance of the detection circuit, and the detection circuit and the signal sending unit 132 are electrically connected.

[0066] When the steel sheet is deformed due to the extrusion of the contact foot 121, the resistance of the ink changes, so that the detection circuit sends a corresponding change in the electrical signal through the signal sending unit 132, when the pressure reaches the preset value, the mainboard 142 receives the corresponding electrical signal sent by the signal sending unit 132, and then sends a start signal to the scanning assembly 14, so that the scanning assembly 14 is started and performs scanning.

[0067] Specifically, as shown in Figure 6 , Figure 7 and Figures 15-17 , the scanning assembly 14 includes a camera module 141 and a mainboard 142, wherein the mainboard 142 is connected with the camera module 141 and the signal sending unit 132 respectively, and the mainboard 142 is used to control the camera module 141 to perform shooting scanning. Specifically, as shown in Figure 8 and Figure 9 , the flexible circuit board of the signal sending unit 132 is provided with a plurality of connecting points, and the mainboard 142 is provided with a plurality of contact springs corresponding to the connecting points one by one, and the contact springs abut against the corresponding connecting points, so as to realize the electrical connection between the mainboard 142 and the flexible circuit board.

[0069] In the embodiment, the elastic member 133 and the contact foot 121 are respectively arranged at two sides of the strain gauge 131 and abut against the opposite two sides of the strain gauge 131, when the contact foot 121 is pressed by the medium to be scanned, the contact foot 121 presses the strain gauge 131, and the strain gauge 131 is compressed by the elastic member 133, when the contact foot 121 is separated from the medium to be scanned, the elastic member 133 can rebound, and the strain gauge 131 and the contact foot 121 return to the initial position.

[0070] In addition, the elastic member 133 of the embodiment can always keep the strain gauge 131 and the contact foot 121 in the abutting state, and the contact foot 121 and the pressure sensing component 13 have a certain initial pressure, so that the contact foot 121 is prevented from moving away from the pressure sensing component 13 in the long-term use process, and the sensitivity of the trigger component 12 and the pressure sensing component 13 is affected.

[0071] Specifically, as shown in Figure 2 , Figure 10 and Figure 11 , the pressure sensing component 13 further comprises a first mounting bracket 134, the signal sending unit 132 and the strain gauge 131 are mounted on the first mounting bracket 134, and the first mounting bracket 134 is mounted in the accommodating cavity of the pen shell 11.

When the two contact feet 121 are pressed by the medium to be scanned, the two contact feet 121 can press the two ends of the strain gauge 131 at the same time, and compared with the single contact foot 121, the strain gauge 131 can generate a larger strain, which is beneficial to improve the sensitivity of the trigger component 12 and the pressure sensing component 13.
