[0046] The following specific implementation methods will further illustrate the present application in conjunction with the above-mentioned drawings. DETAILED DESCRIPTION

[0047] In the embodiments of the present application, when an element is considered to be "connected" to another element, it may be directly connected to the other element or there may be a centrally disposed element at the same time. When an element is considered to be "disposed on" another element, it may be directly disposed on the other element or there may be a centrally disposed element at the same time. In the present application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be a direct connection, or it may be indirectly connected through an intermediate medium, or it may be internal communication between the two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances.

[0048] In addition, the directions described in the embodiments of the present application, such as "up" and "down", refer to the directions of the product when it is in use, such as the directions of a barcode scanning device or a smart terminal when it is used on a horizontal plane.

[0049] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned description of the drawings are intended to cover non-exclusive inclusions.

[0050] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0051] In the related art, a scanning device is provided in devices such as self-service terminals, label recognition terminals, and automatic gates, and the scanning device can scan graphics such as QR codes, bar codes, and labels. When in use, the user can align a graphic such as a QR code with the scanning port of the scanning device, and the scanning device scans the QR code to obtain the corresponding information. For example, the user can align the QR code displayed on the mobile phone with the scanning port of the scanning device, or the user can align the bar code printed on the label on the surface of the object with the scanning port of the scanning device to complete the scanning action.

[0052] However, the code scanning device is usually directly arranged on the operating table of the equipment, so that the code scanning port of the code scanning device is directly exposed on the operating table, resulting in the code scanning device occupying a large space on the operating table and low space utilization.

[0053] To this end, the embodiment of the present application provides a code scanning device and a smart terminal, which can hide the scanning module, reduce the space occupied by the scanning module on the operating table of the whole machine, and improve space utilization. The code scanning device provided by the present application can be applied to smart terminals with code scanning functions, such as self-service terminals, label recognition terminals, automatic gates, etc.

[0054] See also Figure 1 and Figure 2 The code scanning device 10 includes a housing 1, a scanning module 2 and a negative refractive lens 3. The housing 1 is provided with a receiving cavity 11, and the scanning module 2 and the negative refractive lens 3 are both arranged in the receiving cavity 11, and the cavity opening of the receiving cavity 11 is connected to the external space of the housing 1. The housing 1 is also provided with a light-transmitting portion 12, which is located at the cavity opening of the receiving cavity 11, and has light-transmitting ability, and is used for allowing light to enter and exit the interior and exterior of the housing 1.

[0055] The negative refraction lens 3 can negatively refract the light entering the accommodating cavity 11 from the outside of the housing 1, so that the light can enter the scanning module 2. In addition, the negative refraction lens 3 can also negatively refract the light emitted from the inside of the housing 1, so that the light can form an aerial image in the air outside the housing 1.

[0056] The scanning module 2 has a scanning end, and the scanning end can scan and identify the graphics located in front of or near it. A spacing is set between the scanning module 2 and the negative refractive lens 3, and there is an angle between the scanning direction of the scanning module 2 and the center plane of the negative refractive lens 3, and the angle is not equal to 0°. Among them, the scanning direction of the scanning module 2 refers to the direction of the scanning end of the scanning module 2, which is the axial direction of the camera 21 built into the scanning module 2. The center plane refers to a plane that passes through the geometric center of the negative refractive lens 3 and is equidistant from the two sides of the negative refractive lens 3.

[0057] The outside of the housing 1 is provided with a code scanning area 13. The code scanning area 13 and the scanning module 2 are respectively arranged on both sides of the negative refractive lens 3, and the code scanning area 13 and the scanning module 2 are mirror-imaged corresponding to the negative refractive lens 3, that is, the code scanning area 13 and the scanning module 2 are mirror-imaged with the central plane as the symmetry plane, and the code scanning area 13 and the scanning module 2 have equal distances to the negative refractive lens 3 (or the central plane).

[0058] In the description of the embodiments of the present application, the distance between an object and another object refers to the minimum distance between the two objects. For example, the distance between the scanning module 2 and the negative refractive lens 3 refers to the distance between the scanning module 2 and the negative refractive lens 3 in a direction perpendicular to the negative refractive lens 3.

[0059] It is worth noting that the code scanning area 13 is actually the area of ​​the mirror image of the scanning end of the scanning module 2 relative to the negative refractive lens 3. When the relative position between the scanning module 2 and the negative refractive lens 3 is adjusted, the position of the code scanning area 13 is adjusted accordingly. Therefore, the code scanning area 13 and the scanning module 2 described in this embodiment are distributed in a mirror image, which is intended to describe the relative position between the code scanning area 13, the scanning module 2 and the negative refractive lens 3, and does not limit the overall shape or structure of the scanning module 2.

[0060] See also Figure 3 When the light propagates between the code scanning area 13, the negative refraction lens 3 and the scanning module 2, a reverse negative refraction light path is formed. In the reverse negative refraction light path, the light at the code scanning area 13 first passes through the negative refraction lens 3. Under the negative refraction effect of the negative refraction lens 3, the light can propagate in the reverse direction of the scanning direction of the scanning module 2 and enter the scanning end of the scanning module 2.

[0061] See also Figure 2 and Figure 3 Taking a user scanning a QR code on a mobile phone as an example, when performing the code scanning operation, the user can place the mobile phone in the code scanning area 13 outside the shell 1, so that the QR code displayed in the mobile phone interface is displayed in the code scanning area 13. By setting the reverse negative refraction light path, the QR code can be mirrored to a symmetrical position inside the shell 1 (that is, the position of the scanning module 2) so as to be scanned and identified by the scanning module 2.

[0062] The embodiment of the present application sets the scanning module 2 inside the housing 1, and sets the scanning module 2 and the scanning area 13 outside the housing 1 to the two sides of the negative refractive lens 3. When the user places the graphic on the scanning area 13, the light at the scanning area 13 first passes through the negative refractive lens 3. Under the negative refraction of the negative refractive lens 3, the light can propagate in the reverse direction of the scanning direction of the scanning module 2 and enter the scanning end of the scanning module 2, so that the graphic image is copied to the inside of the housing 1 and scanned and identified by the scanning module 2. In addition, the embodiment of the present application hides the scanning module 2 in the housing 1, reduces the space occupied by the scanning module 2 on the surface of the device, improves the space utilization rate, and leaves more space for user operation on the surface of the device, or leaves more space for the installation of other devices, and has stronger expandability.

[0063] In one embodiment of the present application, the cavity opening of the accommodating cavity 11 is arranged upward. The negative refractive lens 3 is arranged at the upper part of the accommodating cavity 11, and the negative refractive lens 3 is fixedly connected to the shell 1. The scanning module 2 is arranged at the lower part of the accommodating cavity 11, that is, the scanning module 2 is located below the negative refractive lens 3. The negative refractive lens 3 is arranged in a horizontal direction, and the scanning end of the scanning module 2 is directed toward the negative refractive lens 3 at a specified inclination angle. The mirror area of ​​the scanning module 2 relative to the negative refractive lens 3 is located above the negative refractive lens 3, that is, the code scanning area 13 is located in the upper space outside the shell 1.

[0064] It can be understood that the scanning module 2 is tilted at a first angle relative to the negative refractive lens 3. The first angle is the angle between the axis of the scanning module 2 (i.e., the axis of the camera 21 built into the scanning module 2) and the center plane of the negative refractive lens 3, that is, the first angle is greater than 0° and less than 90°.

[0065] Taking the example of a user scanning a QR code on a mobile phone, when the user performs the scanning operation, the user can place the mobile phone displaying the QR code on the scanning area 13 above the shell 1 for scanning and identification. The space above the outside of the shell 1 is larger and there are fewer obstructions, making the operation more convenient.

[0066] In one embodiment of the present application, an operation table 4 is disposed at the cavity opening of the accommodating cavity 11, and the light-transmitting portion 12 is disposed on the operation table 4. The operation table 4 can be used to place other objects other than the scanning module 2 or to install other devices.

[0067] It can be understood that the light-transmitting portion 12 is mainly for the light that undergoes negative refraction in the negative refraction lens 3 to pass through, so that the negative refraction lens 3 can copy the graphic image in the code scanning area 13 to the inside of the shell 1, and the negative refraction lens 3 can copy the light image inside the shell 1 to the air outside the shell 1.

[0068] In some embodiments, the negative refractive lens 3 is installed at the opening of the accommodating cavity 11. The side of the negative refractive lens 3 away from the scanning module 2 forms an operating table 4. The negative refractive lens 3 itself has light transmission capability, so that the entire negative refractive lens 3 is provided with a light transmission portion 12.

[0069] It can be understood that the negative refractive lens 3 can negatively refract light and transmit light on the one hand, and on the other hand, the negative refractive lens 3 seals the accommodating cavity 11 to protect the internal components of the shell 1 and provides an operating table 4. Multiple functions can be realized simultaneously through a negative refractive lens 3, simplifying the internal structure of the code scanning device 10.

[0070] In some other feasible embodiments, a cover plate may be provided at the opening of the accommodating cavity 11, the cover plate covers the negative refractive lens 3, the upper surface of the cover plate forms an operating table 4, and the cover plate may be provided with a through hole structure for light to pass through as a light-transmitting portion 12. The cover plate serves to seal the accommodating cavity 11 and protect the lens, thereby improving durability.

[0071] In one embodiment of the present application, a mounting plate 5 is provided inside the shell 1. The mounting plate 5 is located in the accommodating cavity 11. Both sides of the mounting plate 5 are respectively fixed to the shell 1. The mounting plate 5 is used to support and fix the functional components.

[0072] The scanning module 2 is arranged on the mounting plate 5, and the axis of the scanning module 2 is perpendicular to the mounting plate 5. An angle is formed between the mounting plate 5 and the operating table 4, and the angle is not equal to 0°, that is, the mounting plate 5 is tilted at a specified angle as a whole, so that the scanning module 2 can be tilted at the same angle.

[0073] In some embodiments, the scanning end of the scanning module 2 is provided with a camera 21, and the axis of the scanning module 2 or the scanning end of the scanning module 2 is the axis of the camera 21. The scanning module 2 is provided with a reflective cover 22 around the camera 21. The mounting plate 5 is provided with a mounting hole, the mounting hole passes through the mounting plate 5, the size of the mounting hole matches the outer size of the reflective cover 22, the reflective cover 22 is accommodated in the mounting hole with the axis perpendicular to the direction of the mounting plate 5, and the reflective cover 22 is fixedly connected to the mounting plate 5.

[0074] It can be understood that the scanning module 2 shoots the graphics through the camera 21 to scan and identify the graphics, and the reflective cover 22 can increase the shooting range of the camera 21, which is equivalent to expanding the scanning range of the scanning module 2.

[0075] In the code scanning operation, for example, when a user holds a mobile phone to display a QR code, the position or tilt angle of the mobile phone will affect the probability of the scanning module 2 scanning and identifying the QR code. By setting the reflector 22, the scanning range of the scanning module 2 can be expanded, so that light within a certain range near the code scanning area 13 can also enter the scanning module 2 after passing through the negative refractive lens 3, reducing the restriction on the position of the graphics to be identified by the scanning module 2, and improving the code scanning efficiency.

[0076] When the user places the pattern to be scanned and identified in the code scanning area 13, the negative refractive lens 3 can actually mirror the pattern to the front of the reflector 22 to form a mirror image. The scanning module 2 captures the mirror image through the camera 21, thereby scanning and identifying the pattern in the code scanning area 13.

[0077] In one embodiment of the present application, an indicating light emitting member 7 is disposed inside the housing 1 and is disposed on the side of the scanning module 2. The indicating light emitting member 7 is fixedly connected to a surface of the mounting plate 5 facing the negative refractive lens 3.

[0078] The housing 1 is provided with an indication area 14 on the outside, and the indication area 14 is used to indicate the code scanning area 13, so as to facilitate the user to identify the code scanning area 13. The indication area 14 and the indication light emitting member 7 are respectively arranged on both sides of the negative refractive lens 3, and the indication area 14 and the indication light emitting member 7 are mirror-imaged corresponding to the negative refractive lens 3, that is, the indication area 14 and the indication light emitting member 7 are mirror-imaged with the central plane as the symmetry plane, and the indication area 14 and the indication light emitting member 7 are at equal distances from the negative refractive lens 3 (or the central plane). In addition, the distance from the indication light emitting member 7 to the central plane is equal to the distance from the scanning module 2 to the central plane.

[0079] When the light propagates between the indicating light emitting element 7, the negative refraction lens 3 and the indicating area 14, a first positive negative refraction light path is formed. In the first positive negative refraction light path, the indicating light emitting element 7 emits light, which first passes through the negative refraction lens 3, and under the negative refraction effect of the negative refraction lens 3, the light forms an aerial image in the indicating area 14.

[0080] It is worth noting that the indication area 14 is actually the area of ​​the mirror image of the indication light emitting element 7 itself relative to the negative refractive lens 3. When the indication light emitting element 7 emits light, the indication area 14 presents a light spot effect generated by the indication light emitting element 7.

[0081] It can be understood that the indication area 14 has an indication function for the code scanning area 13 and can reflect the location of the code scanning area 13 .

[0082] Taking a user scanning a QR code on a mobile phone as an example, when performing the scanning operation, the user can identify the position of the scanning area 13 through the guidance of the light spot in the indication area 14, and then place the mobile phone displaying the QR code in the scanning area 13 for scanning and identification, which makes it convenient for the user to align the scanning module 2 and improve the efficiency of scanning and identification.

[0083] In some embodiments, the indicating light emitting element 7 is a ring light strip, and the indicating light emitting element 7 is distributed around the scanning module 2. Correspondingly, the indicating area 14 is distributed around the code scanning area 13.

[0084] When the indicating light-emitting component 7 emits light, the negative refractive lens 3 mirrors the aperture of the indicating light-emitting component 7 into the air outside the shell 1, forming a fixed light spot in the indicating area 14. The light spot is distributed around the code scanning area 13, which is convenient for users to identify the code scanning area 13, facilitates user operation, and improves scanning and recognition efficiency.

[0085] In some embodiments, the indicating light emitting member 7 is tilted at a second angle relative to the negative refractive lens 3 , and the first angle is equal to the second angle.

[0086] It can be understood that, since the scanning module 2 is tilted relative to the mirror image of the negative refractive lens 3 outside the housing 1, the scanning area 13 as a whole has a certain tilt angle with the vertical direction. Since the tilt angle of the indicating light emitting element 7 is consistent with the tilt angle of the scanning module 2, the indicating area 14 as a whole has the same tilt angle with the vertical direction.

[0087] In the code scanning operation, for example, when the user holds the mobile phone to display the QR code, the tilt angle of the mobile phone will also affect the probability of the scanning module 2 scanning and identifying the QR code. Only when the user maintains the tilt angle of the mobile phone screen within a certain reasonable range, the QR code displayed on the mobile phone screen can be mirrored to the inside of the shell 1 under the action of the negative refractive lens 3, and scanned and identified by the scanning module 2.

[0088] Ideally, the tilt angle of the mobile phone should be consistent with the tilt angle of the indication area 14, so that the negative refractive lens 3 can mirror the two-dimensional code displayed on the mobile phone screen to the scanning end of the scanning module 2, and the scanning module 2 can correctly scan and identify it.

[0089] When the user displays the mobile phone screen at an inclination angle that deviates from a reasonable range, such as displaying the mobile phone screen in a direction perpendicular to the negative refractive lens 3, even if the mobile phone screen is located in the code scanning area 13, the QR code displayed on the mobile phone screen can be mirrored to the inside of the shell 1, but cannot be scanned and recognized by the scanning module 2.

[0090] It can be understood that when the indicator light emitting member 7 emits light and the negative refractive lens 3 mirrors the light to form a light spot in the air, the light spot as a whole has a certain tilt angle with the vertical direction. The tilted light spot not only indicates the position of the code scanning area 13, but also indicates the tilt angle of the code scanning area 13, which can guide the user to display the mobile phone screen at an inclined angle, and facilitate the user to maintain the tilt angle of the mobile phone screen within a certain reasonable range, so that the two-dimensional code displayed on the mobile phone screen is easier to be scanned and recognized by the scanning module 2, thereby improving the efficiency of scanning and recognition.

[0091] On the other hand, the embodiment of the present application sets the mounting plate 5 at an angle, and fixes the indicating light-emitting component 7 and the scanning module 2 on the mounting plate 5 at the same time, so that the inclination angle of the indicating light-emitting component 7 is consistent with the inclination angle of the scanning module 2, thereby ensuring that the overall inclination angle of the indication area 14 is consistent with the overall inclination angle of the code scanning area 13.

[0092] See also Figure 4 and Figure 5 In one embodiment of the present application, a display module 6 is further disposed inside the housing 1. The display module 6 is disposed on one side of the scanning module 2, and the display module 6 is fixedly connected to a side of the mounting plate 5 facing the negative refractive lens 3. The display module 6 includes but is not limited to an electronic screen. The display module 6 can display specified content to the user, such as human-computer interaction, code scanning status, and other related content.

[0093] The housing 1 is provided with a display area 15 on the outside, and the display area 15 and the display module 6 are respectively provided on both sides of the negative refractive lens 3, and the display area 15 and the display module 6 are mirror-imaged corresponding to the negative refractive lens 3, that is, the display area 15 and the display module 6 are mirror-imaged with the central plane as the symmetry plane, and the display area 15 and the display module 6 are at equal distances from the negative refractive lens 3 (or the central plane). In addition, the distance from the display module 6 to the central plane is equal to the distance from the scanning module 2 to the central plane.

[0094] When the light propagates between the display module 6, the negative refractive lens 3 and the display area 15, a second positive negative refractive light path is formed. In the second positive negative refractive light path, the display module 6 emits light, which first passes through the negative refractive lens 3, and under the negative refraction effect of the negative refractive lens 3, the light forms an aerial image in the display area 15.

[0095] It is worth noting that the display area 15 is actually the area of ​​the mirror image of the display module 6 itself relative to the negative refractive lens 3. By controlling the display module 6 to display designated content, the aerial imaging corresponding to the content can be synchronously presented in the display area 15.

[0096] See also Figure 5 and Figure 6In some embodiments, the display module 6 displays a guide interface 61, which is disposed on one side of the code scanning area 13. The guide interface 61 is used to display a guide graphic, which is used to indicate the code scanning area 13, so as to facilitate the user to identify the code scanning area 13. The guide graphic includes but is not limited to a guide arrow, text, etc.

[0097] It can be understood that after the light of the guidance interface 61 is negatively refracted by the negative refraction lens 3, it can form an aerial image on one side of the code scanning area 13, that is, when the guidance interface 61 displays the guidance pattern, the negative refraction lens 3 will copy the guidance pattern mirror image to one side of the code scanning area 13 to form a fixed aerial image.

[0098] It can be understood that the aerial imaging of the guidance interface 61 has an indicative effect on the code scanning area 13 and can reflect the location of the code scanning area 13 .

[0099] Taking a user scanning a QR code on a mobile phone as an example, when performing the code scanning operation, the user can identify the position of the code scanning area 13 through the guidance of the aerial imaging of the guidance interface 61, and then place the mobile phone displaying the QR code in the code scanning area 13 for scanning and identification, which makes it convenient for the user to align the scanning module 2 and improve the efficiency of code scanning and identification.

[0100] In some embodiments, the display module 6 and the scanning module 2 are fixed to the same mounting plate 5 , and the display module 6 and the scanning module 2 have the same inclination.

[0101] When the guidance interface 61 displays the guidance image, and the negative refractive lens 3 reflects the light in the air to form an aerial image of the guidance interface 61, the aerial image as a whole has a certain tilt angle with the vertical direction. The tilted aerial image not only indicates the position of the code scanning area 13, but also indicates the tilt angle of the code scanning area 13, which can guide the user to display the mobile phone screen at a tilt angle, and facilitate the user to maintain the tilt angle of the mobile phone screen within a certain reasonable range, so that the two-dimensional code displayed on the mobile phone screen is easier to be scanned and recognized by the scanning module 2, thereby improving the efficiency of scanning and recognition.

[0102] On the other hand, in the embodiment of the present application, the mounting plate 5 is tilted and the display module 6 and the scanning module 2 are simultaneously fixed on the mounting plate 5 , thereby ensuring that the tilt angle of the display module 6 is consistent with the tilt angle of the scanning module 2 .

[0103] See also Figure 6 and Figure 7 In one embodiment of the present application, the code scanning device 10 further includes a detection module 8, which is used to detect an object located in the code scanning area 13, and is used to detect whether there is an object in the code scanning area 13 during the code scanning operation. The detection module 8 is disposed on a side of the mounting plate 5 facing the negative refractive lens 3.

[0104] Taking the user scanning the QR code on the mobile phone as an example, when the user is scanning the code, the detection module 8 can detect whether there is an object in the scanning area 13. If so, it is considered that the user has placed the mobile phone in the scanning area 13; if not, it means that the user has not placed the mobile phone in the scanning area 13, and an alarm action can be triggered. The alarm action includes but is not limited to displaying an error message in the display area 15, playing a prompt voice, etc.

[0105] In some embodiments, the detection module 8 may be an infrared sensor module. The detection module 8 may construct an infrared detection network in the code scanning area 13 through infrared rays. When an object is in the code scanning area 13, it will block the infrared rays in the infrared detection network. The detection module 8 may determine whether there is an object in the code scanning area 13 by detecting whether the infrared rays are blocked, thereby completing the detection.

[0106] See also Figure 8 and Fig. 9 The present application also provides a smart terminal 20, which can be a self-service terminal, a tag recognition terminal, an automatic gate or other smart device. The smart terminal 20 includes an operation console 201 and a code scanning device 10 as in any of the above embodiments, and the code scanning device 10 is disposed on the operation console 201. The smart terminal 20 in this embodiment is provided with a display module 6 (see Figure 5 ) As an example, in some embodiments, the smart terminal 20 may not be configured with this module.

[0107] The upper surface of the operating table 201 is provided with a receiving groove, and the code scanning device 10 is received and fixed in the receiving groove, and the upper surface of the code scanning device 10 is flush with the upper surface of the operating table 201. The upper surface of the code scanning device 10 and the upper surface of the operating table 201 together form an operating plane, which has a large area and is unobstructed, and can be used for setting other devices such as keyboards, speakers, etc., and can also leave space for users to place items, which is more expandable.

[0108] The implementation principle of the smart terminal 20 provided in the embodiment of the present application can refer to the relevant description of the code scanning device 10 in the aforementioned embodiment, which will not be repeated here.
