In addition, multiple positioning structures 124 are provided on the sides of the first raised portion 121 and the second raised portion 122 close to the scanning detection window 11, so as to realize the positioning setting between the upper cover molding 16 and the main shell 12 through the multiple positioning structures 124. At the same time, at least one first mounting hole 125 is provided on the first raised portion 121 and the second raised portion 122, so as to realize the bolt-fixed connection of the upper cover molding 16 on the main shell 12 through the multiple first mounting holes 125, and then the light-transmitting glass 15 is pressed and fixed by the upper cover molding 16.

[0075] Further, such as Figure 4 , Figure 7 and Fig. 9 As shown, the upper cover bead 16 is an L-shaped bracket structure, which includes a horizontal portion 161 and a vertical portion 162 that are integrally connected. The horizontal portion 161 is extended along the second direction, and the vertical portion 162 is extended along the third direction.

At the same time, the upper cover bead 16 is located on the light-transmitting glass 15 to press and fix one end of the light-transmitting glass 15. In order to ensure the stability of the light-transmitting glass 15 and improve the overall aesthetics of the device, the end of the horizontal portion 161 away from the vertical portion 162 slightly exceeds the glass detection port 151. In addition, the horizontal portion 161 and the vertical portion 162 are both provided with a plurality of positioning holes 163, and the plurality of positioning holes 163 are respectively provided with a plurality of positioning structures 124 in a one-to-one correspondence.

In the specific implementation process, as shown in FIG. Fig. 9As shown, the upper cover molding 16 presses one end of the light-transmitting glass 15 with a hollow bracket structure, and through the position and structural design between these hollow brackets, the space between the hollow brackets forms a positioning hole 163 between the upper cover molding 16 and the main shell 12, and further, the positioning hole 163 on the vertical portion 162 limits the position of the upper cover molding 16 relative to the main shell 12 in the first direction, and the positioning hole 163 on the horizontal portion 161 limits the position of the upper cover molding 16 relative to the main shell 12 in the second direction, and the first protrusion 121 and the third protrusion 123 limit the position of the upper cover molding 16 relative to the main shell 12 in the third direction, thereby realizing all-round positioning between the upper cover molding 16 and the main shell 12.

Under the premise of not affecting the identification of the document to be identified and the information code, the contact area between the upper cover strip 16 and the light-transmitting glass 15 is increased, thereby improving the stability of the light-transmitting glass 15.

[0077] In addition, if Figure 2 and Fig. 9 As shown, a hollow groove 164 is provided on the end surface of the vertical portion 162 away from the light-transmitting glass 15, and two rotating shaft mounting frames 166 symmetrically arranged along the second direction are provided in the hollow groove 164, and a rotating shaft assembly 19 is provided on each rotating shaft mounting frame 166, so as to realize the rotation connection between one end of the housing upper cover 17 and the upper cover pressure strip 16 through the two rotating shaft assemblies 19. At the same time, in the embodiment of the present application, the rotatable housing upper cover 17 is installed on the upper cover pressure strip 16 through the rotating shaft assembly 19, and has a hovering function, which can flexibly select the position of the housing upper cover 17 relative to the light-transmitting glass 15 according to the intensity and direction of the specific external light, thereby flexibly and effectively eliminating the interference of the external ambient light on the camera during scanning and detection, and greatly improving the success rate of document or information code recognition. When the angle between the housing cover 17 and the light-transmitting glass 15 is the smallest, in the first direction, the housing cover 17 is located above the scanning detection window 11, and at least one side between the housing cover 17 and the light-transmitting glass 15 is opened to provide an entrance and exit for the document to be identified or the information code to be identified to be placed at the scanning detection window 11. Figure 1As shown, on one side of the upper housing cover 17 away from the vertical part 162 and the transparent glass 15, there is an opening, and the other three sides between the upper housing cover 17 and the transparent glass 15 are blocked by the housing structure of the upper housing cover 17 to play a role in light shielding. In some other specific implementation processes, on one side of the upper housing cover 17 away from the vertical part 162 and the side where the third convex part 123 is arranged, there is an opening, and the other two sides between the upper housing cover 17 and the transparent glass 15 are blocked by the housing structure of the upper housing cover 17 to play a role in light shielding, and it is easier for the document to be identified or the information code to be identified to enter and exit.

In detail, the control board 54, the first fill light board 55, the second fill light board 56, the third fill light board 57 and the plurality of light guides 58 are all arranged in the cavity of the housing 1, the control board 54 is fixedly arranged on the housing bottom plate 14, the first fill light board 55 is located above the first camera device 52 and the second camera device 53 along the first direction, the second fill light board 56 and the third fill light board 57 are located below the first camera device 52 and the second camera device 53 along the first direction, and the second fill light board 56 and the third fill light board 57 are respectively located on both sides of the first camera device 52 and the second camera device 53 along the second direction, and the second fill light board 56 is located between the first camera device 52 and the second camera device 53 and the reflector 51. Thus, the first fill light board 55, the second fill light board 56 and the third fill light board 57 are used to perform omnidirectional fill light when the first camera device 52 and the second camera device 53 are shooting. In the specific implementation process, the second fill light board 56 includes an ultraviolet light illumination module, and the first fill light board 55 and the third fill light board 57 both include a white light illumination module and an infrared light illumination module, so that the first fill light board 55, the second fill light board 56 and the third fill light board 57 can use the reflector 51 to fill light with light sources of different wavelengths at different angles for the certificate or information code to be scanned and detected, thereby enabling the first camera device 52 and the second camera device 53 to simultaneously detect various types of certificates or information codes, and accurately identify and classify information. A plurality of light guides 58 are arranged at one end of the shell frame 13 away from the shell detection port 131 along the second direction, and are symmetrically arranged at both ends of the shell frame 13 along the third direction, and the light of the light guides 58 passes through the shell 1, and displays prompt lights of different colors according to the use status of the multifunctional certificate recognition device, so that the user can understand the current status of the device.

[0080] In some embodiments, Figure 8 and Fig.11 – Fig.14 As shown, the multifunctional certificate recognition device fixes and installs the device in the cavity of the shell 1 through the mounting bracket 2, the shell plate frame 13 and the shell bottom plate 14. Specifically, the mounting bracket 2 includes a reflector bracket 21 and an auxiliary bracket 22.

The bracket body 211 is a plate structure inclined relative to the ground, and one end of the bracket body 211 abuts against the shell bottom plate 14. Two limit frames 212 are arranged on the inclined end surface of the bracket body 211 away from the ground, and are respectively located at the two ends of the bracket body 211 along the third direction. An inverted isosceles trapezoidal groove 2111 is formed between the two limit frames 212 and the bracket body 211.

Since the upper bottom of the inverted isosceles trapezoidal groove 2111 is located at one end of the bracket body 211 abutting against the bottom plate 14 of the shell, the reflector 51 can be positioned on the reflector bracket 21 through the shape and size design of the reflector 51 and the inverted isosceles trapezoidal groove 2111. The inverted isosceles trapezoidal groove 2111 plays a role of positioning support. At the same time, the reflector 51 adopts an isosceles trapezoidal shape design, and the reduced area is the area that the reflector 51 will not use. Only the area used by the reflector 51 is retained, thereby reducing the area of ​​the reflector 51. However, it should be understood that the lengths of the sides of the isosceles trapezoid used by the reflector 51 need to be specifically designed according to the shape of the scanning detection window 11, the relative positions of the first camera device 52 and the second camera device 53, and other set conditions, so as to ensure that the document to be identified or the information code placed at the scanning detection window 11 can be completely captured by the first camera device 52 and the second camera device 53 under the reflection effect of the reflector 51. In order to achieve a fixed connection between the reflector bracket 21 and the auxiliary bracket 22, a plurality of fixing grooves 214 are arranged on the inclined end surface of the bracket body 211 away from the ground, each fixing groove 214 is a groove structure extending along the first direction toward the direction close to the ground, and the plurality of fixing grooves 214 are arranged at both ends of the bracket body 211 along the third direction.

The shape and size of the opening formed between the two pressing plates 222 are adapted to the shape and size of the inverted isosceles trapezoidal groove 2111 and the reflector 51. When the reflector bracket 21 and the auxiliary bracket 22 are fixedly connected, the two pressing plates 222 respectively press and fix the two edges of the reflector 51 accommodated in the inverted isosceles trapezoidal groove 2111, thereby realizing the fixed assembly of the reflector 51 without affecting the reflective effect of the reflector 51.

[0096] In the embodiments of the present application, Figure 4 – Figure 7 , Fig.11 and Fig.26As shown, the document information reading device 4 includes an antenna board 41, a card reader board 43 and an ID card security module 44. The card reader board 43 is electrically connected to the power board 31, and the antenna board 41 is used to obtain the chip information of the document to be identified. The card reader board 43 reads the chip information in various types of electronic documents through the antenna board 41. If the document is a document other than a resident ID card, the card reader board 43 transmits the information read by the antenna board 41 to the power board 31, and the power board 31 transmits the information to the host computer; if the document is a resident ID card, the card reader board 43 transmits the information read by the antenna board 41 to the ID card security module 44 for decryption, and then sends the decrypted information to the power board 31, and then the power board 31 transmits it to the host computer. In detail, the shell frame 13 is provided with an antenna installation groove that matches the shape and size of the antenna plate 41. The antenna plate 41 is arranged in the antenna installation groove and is located between the shell frame 13 and the light-transmitting glass 15. The antenna plate 41 is limited and fixed to the shell frame 13 by the light-transmitting glass 15. In the specific implementation process, the shell frame 13 is provided with two antenna blocks 130. Correspondingly, the antenna plate 41 is provided with a plurality of slot structures. When the antenna plate 41 is assembled on the shell frame 13, the antenna plate 41 is respectively limited and fixed in the second direction and the third direction by the two antenna blocks 130. In addition, the card reader 43 and the ID card security module 44 are arranged in the space between the auxiliary bracket 22 and the main shell 12. The card reader board 43 is extended along the first direction and arranged in the cavity of the shell 1, and its two sides along the first direction are respectively abutted against the shell plate frame 13 and the shell bottom plate 14, so as to limit the displacement of the card reader board 43 in the first direction through the shell plate frame 13 and the shell bottom plate 14, and at the same time, two limit columns 137 are arranged at one end of the shell plate frame 13 away from the shell detection port 131 along the second direction, each limit column 137 is extended along the first direction, and in the third direction, the two limit columns 137 are respectively located at the two ends of the shell plate frame 13, and the two sides of the card reader board 43 along the third direction are respectively clamped in the two limit columns 137, so as to limit the position of the card reader board 43 in the second direction and the third direction through the two limit columns 137, thereby the card reader board 43 is fully limited and fixed through the two limit columns 137, the shell plate frame 13 and the shell bottom plate 14. The ID card security module 44 is arranged on one side surface of the card reader board 43, and one end of the ID card security module 44 is abutted and fixed on the shell plate frame 13, and the other end of the ID card security module 44 is fixedly connected to the card reader board 43, thereby realizing the fixed connection of the ID card security module 44 in the cavity of the shell 1 through the shell plate frame 13 and the card reader board 43.

[0097] Furthermore, the document information reading device 4 also includes two photosensors (not shown in the figure). In detail, at least one photosensor is arranged between the end of the light-transmitting glass 15 away from the glass detection port 151 and the antenna board 41, and each photosensor is sleeved in an EVA ring 42, so that the photosensor is isolated from the outside through the EVA ring 42, so as to avoid the light of the first fill light board 55, the second fill light board 56, and the third fill light board 57 from affecting the photosensor. In the specific implementation process, the document information reading device 4 includes two photosensors, and the two photosensors are evenly distributed on the antenna board 41 away from the end of the scanning detection window 11, so as to determine whether a document is inserted by monitoring the changes in the brightness of the light environment around the device through the photosensors.

[0098] When a certificate or paper barcode or QR code is placed in, the environment around the photosensitive sensor becomes dark, and it outputs an electrical signal indicating that a certificate has been placed in the device to the power board 31, so as to control the device to open the antenna board 41 through the power board 31, and then read the relevant information stored in the electronic certificate in a timely manner. When identifying the information code on an electronic device (including but not limited to a mobile phone) with a near field communication (NFC) function, since the screen of the electronic device has its own brightness, it does not need to be close to the device to be effectively recognized by the camera. At this time, the ambient light brightness around the photosensitive sensor does not change significantly, so it will not be detected by the photosensitive sensor, so the device will not open the antenna board 41, that is, the device antenna remains in a closed state, thereby effectively solving the problem that when the device reads the information code on the electronic device with the NFC function, the NFC interface is actively triggered to open by the antenna board 41, resulting in the failure of the device to detect and identify the information code. It should be noted that when the device is in an idle state, the antenna is in a closed state.

[0099] In the specific implementation process, Figure 7 , Figure 8 as well as Fig.11 – Fig.14 As shown, the third support column 132, the sixth support column 133, the first support column 213, the first fixing column 223 and the second fixing column 227 in the multifunctional document recognition device are all provided with reinforcing ribs to improve the stability of the support and fixed connection between the various components.

[0100] At the same time, if Figure 4 , Figure 5 and Figure 7As shown, a plurality of support frames 139 are arranged on one end of the shell plate frame 13 close to the second protrusion 122, and the plurality of support frames 139 are arranged in sequence along the third direction. Furthermore, the plurality of support frames 139, two limit blocks 136, two antenna blocks 130 and a structure with through holes are at the same height in the first direction, so that the light-transmitting glass 15 can be supported and fixed by the aforementioned structure.

[0101] In addition, the inclination angle of the reflector 51 relative to the ground is 30°, and by setting the shooting angles of the image camera 521 and the information code camera 531, it is ensured that the image camera 521 and the information code camera 531 can obtain a complete image to be identified through the reflection effect of the reflector 51. Setting the inclination angle of the reflector 51 relative to the ground to 30° can effectively reduce the size of the space occupied by the reflector 51 in the first direction, thereby reducing the overall height and volume of the equipment.

[0102] In summary, the present application discloses a multifunctional document recognition device, which is more compact, flexible and lightweight while ensuring the image acquisition quality, recognition speed and recognition success rate of various documents or information codes to be recognized, and can also be adapted to various occasions that require the size of the device, greatly broadening the application scenarios of such devices. At the same time, the multifunctional document recognition device effectively avoids the failure of information code recognition due to the automatic triggering of the device antenna by the NFC of the electronic device, further improving the recognition success rate of various documents or information codes to be recognized.
