[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0027] In addition, the descriptions of "first", "second", etc. in the present invention are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] In the related art, a camera and a light board are provided in the passport reader. The camera and the light board are both provided at the bottom of the passport reader. A transparent area and a shooting area are provided at the top of the passport reader. The transparent area is used to place the passport. The transparent area is supplemented with light by the light board. The camera is arranged toward the shooting area. The image at the transparent area is transmitted to the shooting area through the reflective structure so that the camera can aim at the shooting area. However, in this design, the camera and the light board are both provided at the bottom of the passport reader. The camera needs to be aimed at the shooting area, which causes the light board to be provided close to the transparent area. The light emitted by the light board is easy to produce a light spot on the passport. The light is not uniform enough, which causes the camera to shoot unclearly and the image clarity is not high. That is, the space of the passport reader is limited. As a portable device, the space cannot be very large. The camera and the light board are both provided at the bottom. The camera needs to be aimed at the shooting area on one side of the transparent area. This can only result in the camera being located at the edge of the bottom, the light board being located on the side of the camera away from the edge, and the light board being closer to the transparent area.

[0029] Please refer to Figures 1 to 5The present invention provides a passport reader 100, which includes: a shell 10, a transparent placement area 151 is provided on the top of the shell 10; a camera assembly 20, which is arranged in the shell 10 and away from the bottom of the shell 10; a light board 30, which is arranged at the bottom of the shell 10 and is arranged toward an end away from the transparent placement area 151, and a light source emitting end of the light board 30 (not marked in the figure) is arranged toward the transparent placement area 151; and a reflection structure 40, which is installed in the shell 10 and is used to reflect the image of the transparent placement area 151 to the shooting end (not marked in the figure) of the camera assembly 20.

[0030] Specifically, when the light panel is closer to the illuminated object, the light is more concentrated, and the focusing effect of the light is stronger at close range, resulting in excessive local brightness, which easily produces light spots.

[0031] Therefore, in the present invention, the passport reader 100 includes a housing 10, a camera assembly 20, a light board 30 and a reflective structure 40. The housing 10 is used to protect and install internal components. The top of the housing 10 has a transparent placement area 151. The camera assembly 20 is arranged inside the housing 10, away from the bottom of the housing 10, and the camera assembly 20 is used for shooting and imaging; while the light board 30 is separately arranged at the bottom of the housing 10, away from the transparent placement area 151, and emits a light source toward the transparent placement area 151 for supplementary light; the reflective structure 40 is used to transmit the image of the transparent placement area 151 to the shooting end of the shooting assembly for shooting. Since the light board 30 is arranged away from the transparent placement area 151, the light emitted is more uniform, so that the image of the transparent placement area 151 is not easy to form a light spot, the image is clearer, and the image is transmitted to the camera assembly 20 for shooting, and the image is clearer.

[0032] The camera assembly 20 can be installed in the middle of the housing 10 or on the top of the housing 10, as long as it is arranged away from the bottom of the housing 10 so that the light board 30 has enough installation space and can be installed away from the transparent placement area 151. The light intensity decays rapidly with the increase of distance. Therefore, when the light board 30 is far away from the illuminated object, the light emitted by the light board 30 will have more time and space to diverge before reaching the transparent placement area 151, and the light distribution becomes more uniform, reducing the formation of light spots, making the image clearer.

[0033] The installation distance between the light board 30 and the transparent placement area 151 can be set to the outermost end of the bottom of the housing 10, or can be set to be slightly away from the transparent placement area 151. The specific installation position can be selected according to actual needs. By adjusting the distance between the light board 30 and the transparent placement area 151, the focusing degree and distribution range of the light can be controlled to achieve the desired fill light effect.

[0034] The specific structure of the reflective structure 40 can be set according to the specific installation position of the camera assembly 20. The reflective structure 40 can include multiple mirrors to reflect the image of the transparent placement area 151 to the shooting end of the shooting assembly; the reflective structure 40 can also adopt structures such as lenses and refractors.

[0035] The fill light of the light board 30 includes white light, infrared light, ultraviolet light, etc., and specific light sources can be added according to actual needs.

[0036] In addition, in the related art, an algorithm is set in the device to repair the image with light spots or unclear images, but such method is slow and costly, resulting in long reading time, long waiting time and low customs clearance efficiency. In the present invention, there is no need to set an algorithm, nor to expand the space of the passport reader 100, adjust the layout of the internal components, and move the camera assembly 20 from the bottom of the housing 10 to another installation position to improve the clarity of the image.

[0037] The transparent placement area 151 can be set as a transparent plate 15, or can be directly set as an opening 14, as long as the light on the light board 30 can be evenly projected onto the photographed document (such as a passport).

[0038] The technical solution of the present invention arranges the light board 30 at the bottom of the shell 10 and the camera assembly 20 away from the bottom of the shell 10, so that the light board 30 has a larger installation space at the bottom of the shell 10, and can be arranged toward the end away from the transparent placement area 151. The light board 30 is far away from the transparent placement area 151, so the light irradiated on the transparent placement area 151 is more uniform, which can effectively reduce the light spot and achieve a more uniform fill light effect. The image of the transparent placement area 151 is reflected to the shooting end of the camera assembly 20 through the reflection structure 40, so that the image taken by the camera assembly 20 is clearer, the imaging effect is good, and the speed is fast.

[0039] In the embodiment of the present invention, the bottom of the housing 10 is convex outward to form a placement cavity 121, and the lamp board 30 is installed in the placement cavity 121 and is tilted.

[0040] In detail, Figure 4 The lamp board 30 is installed through a protruding placement cavity 121 at the bottom. The lamp board 30 can be installed in the placement cavity 121 through a supporting structure, or the side wall of the placement cavity 121 can be set as an inclined side wall, and the lamp board 30 is directly installed on the side wall.

[0041] This design can form a light panel 30 further away from the transparent placement area 151. As the distance increases, the light has a chance to spread more widely, making the overall lighting more uniform. By adjusting the distance between the light source and the illuminated object, the focus and distribution range of the light can be controlled to achieve the desired lighting effect.

[0042] When the light panel 30 is far away from the illuminated object, the light travels over a longer distance and more scattering and diffraction will occur, thereby making the light distribution more uniform and reducing the formation of light spots.

[0043] At the same time, if Figure 4 By introducing the light from the light board 30 from the side, the shadow directly below the document can be effectively reduced, avoiding the problems of overexposure and excessive reflection, thereby making the imaging more natural and uniform, and helping to improve the imaging quality.

[0044] In an embodiment of the present invention, the shell 10 includes an outer shell 11 and an inner shell 12, the inner shell 12 is installed inside the outer shell 11, the top of the inner shell 12 is open, and the bottom of the inner shell 12 protrudes toward the outer shell 11 to form the placement cavity 121; the placement cavity 121 is provided with an installation opening (not marked in the figure) on the side away from the transparent placement area 151, and the light board 30 is fixedly connected to the inner shell 12 and covers the installation opening.

[0045] It is worth noting that the housing 10 is configured to include an outer housing 11 and an inner housing 12. The two layers of housing 10 are configured, the outer housing 11 is used to protect and install internal components, and the inner housing 12 is used to install the light board 30. Figure 4 The placement cavity 121 is arranged in an inclined cavity, and a mounting opening is arranged on the side wall away from the transparent placement area 151. The lamp board 30 is fixedly connected to the side wall from the outside of the placement cavity 121 and covers the mounting opening, so that the lamp body of the lamp board 30 is located in the placement cavity 121, and light is emitted from the placement cavity 121 toward the transparent placement area 151. This design is convenient for installation and maintenance, and the lamp board 30 can be installed directly from the outside, and heat dissipation can be improved, which helps to extend the life of the lamp board 30 and maintain its stable performance. The outer shell 11 includes an upper shell and a lower shell for installation and maintenance.

[0046] In an embodiment of the present invention, the shell 10 also includes a supporting shell 13, which is located inside the inner shell 12 and connected to the top of the inner shell 12. The camera assembly 20 is installed in the supporting shell 13, and the shooting end of the camera assembly 20 is arranged toward the inside of the supporting shell 13; a reflection port 1311 is provided on the side wall of the supporting shell 13 facing the transparent placement area 151, so that the reflection structure 40 reflects the image of the transparent placement area 151 to the shooting end of the camera assembly 20 through the reflection port 1311.

[0047] Specifically, Figure 4 , a support shell 13 is also provided, the support shell 13 is located at the top of the inner shell 12, and is spaced apart from the light board 30. The support shell 13 is used to install the camera assembly 20, and the support shell 13 is located on one side of the transparent placement area 151. The light board 30 is spaced apart from the bottom of the support shell 13. Since the camera assembly 20 is located in a relatively closed space, it is easier to disassemble and assemble during design maintenance, reducing the difficulty of maintenance.

[0048] By installing the camera assembly 20 in the support housing 13, better physical protection can be provided to prevent it from being affected by external impact or environmental factors, thereby extending its service life. In addition, the fixed placement makes the position of the camera assembly 20 more stable and is not easily shaken by external vibration or movement, thereby ensuring image quality.

[0049] At the same time, by providing the reflection port 1311 to cooperate with the reflection structure 40, the camera assembly 20 can accurately capture the image of the passport document and cooperate with the light board 30 to obtain a clearer and higher quality image.

[0050] In an embodiment of the present invention, the supporting shell 13 includes a supporting frame 131 and a cover plate 132. The supporting frame 131 is installed inside the inner shell 12. The top of the supporting frame 131 is open. The cover plate 132 is covered on the top of the supporting frame 131. The camera assembly 20 is connected to the cover plate 132.

[0051] In detail, the supporting shell 13 is configured to include a supporting frame 131 and a cover plate 132. The camera assembly 20 is installed in the supporting frame 131 through the cover plate 132, so that the camera assembly 20 can be installed more conveniently. When the camera assembly 20 needs to be replaced or repaired, only the cover plate 132 needs to be removed.

[0052] In addition, a fixing plate 1313 is provided at the position of the camera assembly 20, and the fixing plate 1313 is sleeved on the outer end of the camera assembly 20 and fixedly connected to the support frame 131, so as to further fix the camera assembly 20. At the same time, the upper shell of the outer shell 11 is partially covered on the cover plate 132 to prevent dust from falling, thereby further playing a protective role.

[0053] In an embodiment of the present invention, reinforcing ribs 1312 are further provided inside the support frame 131 , and the reinforcing ribs 1312 are located on both sides of the support frame 131 , so that an installation cavity 1314 is formed in the middle of the support frame 131 , and the installation cavity 1314 is used to install the camera assembly 20 .

[0054] It is worth noting that Figure 5 A reinforcing rib 1312 is also provided inside the support frame 131 , which can increase the overall rigidity and stability of the support frame 131 , prevent deformation or twisting when subjected to external force, improve fatigue resistance, and thus extend the service life of the support frame 131 .

[0055] The reinforcing ribs 1312 are located on both sides of the support frame 131, so that the middle of the support frame 131 is recessed with an installation space for the camera assembly 20. The reinforcing ribs 1312 can be used as a positioning reference during assembly to help accurately fix the position of the camera assembly 20, making the assembly process easier.

[0056] The camera assembly 20 includes a circuit board 21 and a camera 22. The fixing plate 1313 is located in the above-mentioned installation space. The fixing plate 1313 is provided with a socket hole for the camera 22 to extend into. The circuit board 21 of the camera assembly 20 is fixedly connected to the fixing plate 1313, thereby firmly fixing the camera assembly 20 to prevent shaking and improve the clarity of image capture.

[0057] In an embodiment of the present invention, the side wall of the inner shell 12 close to the transparent placement area 151 is inclined close to the transparent placement area 151, and the side wall of the support shell 13 away from the transparent placement area 151 is inclined toward the side away from the transparent placement area 151; the reflective structure 40 includes a first reflective lens (not shown in the figure) and a second reflective lens (not shown in the figure), the first reflective lens is installed on the inclined side wall of the inner shell 12, and the second reflective lens is installed on the inclined side wall of the support shell 13, the first reflective lens and the second reflective lens are connected through the reflection port 1311, and the shooting area of ​​the camera assembly 20 is arranged toward the second reflective lens.

[0058] Specifically, Figure 4The side wall of the inner shell 12 is tilted, and the side wall of the supporting shell 13 is also tilted, so that the two side walls are arranged at an angle, and the first reflecting lens and the second reflecting lens are respectively installed on the two side walls, and the first reflecting lens and the second reflecting lens are also arranged at an angle, so that the first reflecting lens can reflect the image obtained from the transparent placement area 151 to the second reflecting lens through the reflection port 1311,

[0059] By using the first reflective lens and the second reflective lens and setting them at an angle, the camera assembly 20 can capture the document image, realize a more complex optical path design in a limited space, and contribute to the miniaturization design of the equipment, so that the entire device occupies less space and improves space utilization efficiency.

[0060] In an embodiment of the present invention, the angle formed by the first reflective lens and the second reflective lens is 90 degrees.

[0061] It is worth noting that the 90-degree angle enables the light to achieve a vertical viewing angle conversion after two reflections, so that the image can be transmitted to the camera assembly 20 in a predetermined manner for imaging. By designing a 90-degree reflection path, the vertical space can be effectively utilized, making the device more compact as a whole, and making the alignment between the two reflective lenses simpler and more intuitive, reducing the workload of debugging and calibration.

[0062] At the same time, by controlling the number of reflections and the path length, the quality of the final image can be improved to achieve the best shooting effect.

[0063] In an embodiment of the present invention, a first placement groove 122 is recessed on the inclined side wall of the inner shell 12, and a second placement groove 133 is recessed on the inclined side wall of the supporting shell 13. The first reflective lens is installed in the first placement groove 122, and the second reflective lens is installed in the second placement groove 133.

[0064] Specifically, the specific installation method of the first reflective lens and the second reflective lens can be set according to actual needs, and can be connected and fixed by a fixing piece, or can be fixed by setting a groove. Figure 4 , by providing placement grooves on the two side walls to install the first reflective lens and the second reflective lens,

[0065] The design of the first placement groove 122 and the second placement groove 133 can ensure that the two reflective lenses are firmly installed in their positions, reducing the risk of lens displacement due to vibration or collision, thereby ensuring the long-term stable operation of the system. It can also provide additional protection for the reflective lenses to prevent the lenses from being directly hit or scratched, thereby extending the service life of the lenses. The design of the placement groove makes the installation of the reflective lenses simple and quick, and also facilitates subsequent maintenance work. If the lens needs to be replaced, just replace the lens in the placement groove.

[0066] By providing a placement slot at a preset position, the position and angle of the reflective lens can be precisely controlled, which is beneficial for precisely adjusting the optical path and ensuring that the camera assembly 20 can accurately capture images.

[0067] In the embodiment of the present invention, an opening 14 is provided on the top of the housing 10 , a transparent plate 15 is installed at the opening 14 , the transparent plate 15 forms the transparent placement area 151 , and the camera assembly 20 is located on one side of the transparent plate 15 .

[0068] In detail, a transparent plate 15 is provided at the opening 14 of the shell 10 to form a transparent placement area 151, which is convenient for preventing documents such as passports from being placed therein. The transparent plate 15 can ensure that the camera assembly 20 can obtain high-quality images. Since the transparent plate 15 is usually smooth and transparent, it will not interfere with the imaging, thereby ensuring the clarity of the document details and achieving clear imaging.

[0069] Furthermore, the transparent plate 15 can protect the internal camera assembly 20 from external pollution or damage to a certain extent, especially when used in public places, it can reduce the impact of dust, stains, etc. on the equipment and is also easy to clean.

[0070] In addition, if Figure 1 A protective cover 50 is also provided above the transparent plate 15, and an opening 14 on one side of the protective cover 50 is used to insert and place documents such as passports. By providing the protective cover 50, the transparent plate 15 can be protected and prevented from being bumped, thereby extending the service life. Dust and the like can be prevented from falling on the transparent plate 15, and the transparent plate 15 can be kept clean to ensure image quality and visual effects. The glare caused by external light sources can be reduced to a certain extent, especially in a strong light environment, which helps to improve the display effect. A pressing block 51 is also provided below the protective cover 50 to flatten the passport.
