It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0044] See also Figures 1 to 3 , Figure 1 is a cross-sectional view of a portion of the structure of the smart vending cabinet provided in this application, Figure 2 yes Figure 1 An enlarged view of part A of one embodiment of the invention, Figure 3 yes Figure 1 The present application provides an identification device 100, which includes a device body 110, an identification code 120 and a collection component 130. The identification device 100 can be applied to a smart vending cabinet 10.

[0045] In some embodiments, the device body 110 is used to be embedded in the door assembly 101 of the smart vending cabinet 10. The identification code 120 is set in the device body 110. The collection component 130 is used to be embedded in the box 102 of the smart vending cabinet 10. When the door assembly 101 is in a closed state, the identification code 120 is located within the field of view of the collection component 130.

[0046] After the device body 110 is embedded in the door assembly 101 of the smart vending cabinet 10, at least part of the device body 110 is exposed to the door assembly 101. After the collection component 130 is embedded in the box 102 of the smart vending cabinet 10, the collection part 131 of the collection component 130 is exposed to the box 102. When the door assembly 101 is in a closed state, the identification code 120 and at least part of the device body 110 are located within the field of view of the collection part 131. Whether the information collected by the collection component 130 meets the preset information that matches the information carried by the identification code 120 is used as the basis for judging whether the door assembly 101 is opened or closed. When the information collected by the collection component 130 does not match the preset information matching the information carried by the identification code 120, it can be determined that the door body component 101 is in the open state, and the smart vending cabinet 10 is opened or maintains the selling state. When the information collected by the collection component 130 matches the preset information matching the information carried by the identification code 120, it can be determined that the door body component 101 is in the closed state, and the smart vending cabinet 10 ends the selling state. The identification code is unique and not easy to be counterfeited. Therefore, when the door body component 101 is in the open state, if the information collected by the collection component 130 does not match the preset information matching the information carried by the identification code 120, the door body component 101 will remain in the open state, and the smart vending cabinet 10 will remain in the selling state, thereby preventing the theft of goods in the smart vending cabinet 10 and improving security.

[0047] The identification code 120 has a high recognition fault tolerance capability. For example, the identification code 120 can still be collected by the collection component 130 when it is partially blocked. The identification code 120 is unique and has a high anti-counterfeiting capability. The identification code 120 is not easy to be forged, thereby further improving the security of the smart vending cabinet 10. The identification code 120 includes but is not limited to a two-dimensional code, a one-dimensional code, numbers, letters, a combination of numbers and letters, and a picture.

[0048] In some embodiments, please refer to Figures 4 to 6 , Figure 4 is a schematic diagram of the three-dimensional structure of the device body of the identification device provided by the present application; Figure 5 It is a structural schematic diagram of a device body of the identification device provided by the present application from one perspective; Figure 6 yes Figure 5 The device body 110 includes a housing 111. The housing 111 has a first opening 1111, a second opening 1112 and a collection chamber 111a. The first opening 1111, the collection chamber 111a and the second opening 1112 are connected. The first opening 1111 faces the collection assembly 130. The second opening 1112 faces the identification code 120.

[0049] The housing 111 may be a prism structure or a cylindrical structure, but is not limited thereto. The prism structure includes but is not limited to a quadrangular prism structure, a pentagonal prism structure, a hexagonal prism structure, and an octagonal prism structure. This embodiment takes the housing 111 as an example of a quadrangular prism structure.

[0050] The housing 111 includes two first side plates 1113 and two second side plates 1114 arranged opposite to each other. The two first side plates 1113 and the two second side plates 1114 surround and form a collection chamber 111a. The two first side plates 1113 and the two second side plates 1114 are fixedly connected or integrally formed. The two first side plates 1113 and the two second side plates 1114 are connected to each other. The planes where the two first side panels 1113 are located are perpendicular to the planes where the two second side panels 1114 are located; or the plane where a first side panel 1113 is located is at an acute angle to the plane where a second side panel 1114 is located, the plane where a first side panel 1113 is located is at an obtuse angle to the plane where another second side panel 1114 is located, the plane where another first side panel 1113 is located is at an obtuse angle to the plane where a second side panel 1114 is located, and the plane where another first side panel 1113 is located is at an acute angle to the plane where another second side panel 1114 is located, so that the shell 111 has a cube structure, a rectangular parallelepiped structure, or other quadrangular prism structures other than the cube structure and the rectangular parallelepiped structure.

[0051] The shell 111 can be made of a light-proof material so that the light in the collection cavity 111a will not leak through the shell 111, ensuring that the collection component 130 can recognize the identification code 120 of the device body 110. At the same time, the interference of ambient light on the collection component 130 is eliminated, avoiding the collection component 130 from being unable to collect the identification code 120 under the interference of ambient light.

[0052] The material of the shell 111 can be selected from polypropylene, polyethylene, and polyester, but is not limited thereto. That is, the material of the two first side panels 1113 and the two second side panels 1114 can be polypropylene, polyethylene, and polyester. Polypropylene, polyethylene, and polyester have the advantages of being light, not easy to deform, not easy to break, and not rusting, and can ensure the service life of the shell 111. At the same time, polypropylene, polyethylene, and polyester are all light-proof materials, which can not only prevent the light of the collection cavity 111a from leaking through the shell 111, ensuring that the collection component 130 can recognize the identification code 120 of the device body 110, but also eliminate the interference of ambient light on the collection component 130, and avoid the collection component 130 from being unable to collect the identification code 120 of the device body 110 under the interference of ambient light. Of course, the material of the shell 111 can also be selected from at least one of metals such as iron, aluminum, tin, copper, gold, and silver.

[0053] The first opening 1111, the collection chamber 111a and the second opening 1112 are connected. The first opening 1111 faces the collection assembly 130, and the collection portion 131 of the collection assembly 130 corresponds to the first opening 1111. The second opening 1112 faces the identification code 120. When the door assembly 101 is in a closed state, the identification code 120 is located within the field of view of the collection portion 131.

[0054] In some embodiments, please refer to Figure 7 , Figure 7 1 is a bottom view of the device body of the identification device provided in the present application. The device body 110 includes a light guide plate 112. The light guide plate 112 covers the second opening 1112. The identification code 120 is disposed on the light guide plate 112.

[0055] The light guide plate 112 is used to guide light into the collection cavity 111a. The identification code 120 can be set on the side of the light guide plate 112 facing the collection cavity 111a, or on the side of the light guide plate 112 facing away from the collection cavity 111a, and the surface of the identification code 120 carrying information faces the collection cavity 111a. The area of ​​the identification code 120 is smaller than the area of ​​the light guide plate 112 where it is located, that is, at least part of the light guide plate 112 where the identification code 120 is located is not provided with the identification code 120, so that the remaining part of the light guide plate 112 where the identification code 120 is not provided can be used to guide light into the collection cavity 111a. Since the shell 111 is selected from a light-proof material, the light guided into the collection cavity 111a by the light guide plate 112 will not leak through the shell 111, thereby ensuring that the collection cavity 111a has sufficient brightness.

[0056] The light guide plate 112 has light guide points of various densities and sizes, so that the light guide plate 112 can evenly guide light into the collection cavity 111a. At the same time, the light guide plate 112 is also used to improve the utilization rate of light. The identification code 120 of the identification device 100 is set on the light guide plate 112, and the area of ​​the identification code 120 is smaller than the area of ​​the light guide plate 112 where it is located. The light introduced into the collection cavity 111a by the light guide plate 112 is sufficient to illuminate the collection cavity 111a and the identification code 120.

[0057] In some embodiments, please refer to Figure 8 , Figure 8 1 is a top view of the device body of the identification device provided in the present application. The device body 110 further includes a light-transmitting member 113. The light-transmitting member 113 covers the first opening 1111. The light-transmitting member 113 is a light-transmitting plate, a convex lens or a concave lens.

[0058] The light-transmitting member 113 covers the first opening 1111 . The light guide plate 112 and the light-transmitting member 113 are disposed opposite to each other. The collecting component 130 can collect the identification code 120 disposed on the light guide plate 112 through the light-transmitting member 113 .

[0059] The light-transmitting member 113 may be made of a transparent material, for example, the light-transmitting member 113 may be a glass light-transmitting member, a crystal light-transmitting member, a transparent silicone light-transmitting member, a poly(methyl methacrylate), AMMP light-transmitting member, a polycarbonate, PC light-transmitting member, but not limited thereto. The light-transmitting member 113 may be a light-transmitting plate, a convex lens or a concave lens, but not limited thereto. The light-transmitting member 113 has certain dustproof and waterproof capabilities.

[0060] In some embodiments, please refer to Fig. 9 , Fig. 9 It is a structural schematic diagram of the device body of the identification device provided by the present application from another perspective. The light guide plate 112 includes a first light guide portion 1121 and a second light guide portion 1122. The first light guide portion 1121 covers the second opening 1112. The identification code 120 is set on the first light guide portion 1121. The second light guide portion 1122 is connected to the first light guide portion 1121. The second light guide portion 1122 is used to guide the light emitted by the first light source assembly 103 into the collection cavity 111a through the second light guide portion 1122 and the first light guide portion 1121.

[0061] The identification code 120 may be disposed on a side of the first light guide portion 1121 facing the collection cavity 111a, or on a side of the first light guide portion 1121 facing away from the collection cavity 111a, with the surface of the identification code 120 carrying information facing the collection cavity 111a. The second light guide portion 1122 is fixed or integrally formed on the edge of the first light guide portion 1121, and extends from the edge of the first light guide portion 1121 toward a direction away from the first light guide portion 1121, the plane where the first light guide portion 1121 is located is perpendicular to the plane where the second light guide portion 1122 is located, or the plane where the first light guide portion 1121 is located forms an acute angle or an obtuse angle with the plane where the second light guide portion 1122 is located; or the second light guide portion 1122 is fixed or integrally formed on the surface of the first light guide portion 1121 that is away from the collection cavity 111a, or the second light guide portion 1122 is provided on the door body assembly 101, the plane where the first light guide portion 1121 is located is parallel to the plane where the second light guide portion 1122 is located, or the plane where the first light guide portion 1121 is located forms a certain angle with the plane where the second light guide portion 1122 is located. The light emitting surface of the second light guide portion 1122 is coupled with the light incident surface of the first light guide portion 1121. The second light guide portion 1122 is used to guide the light emitted by the first light source assembly 103 of the smart vending cabinet 10 into the collection cavity 111 a through the second light guide portion 1122 and the first light guide portion 1121 .

[0062] The identification code 120 can be set on the first light guide part 1121 by printing, pasting, etc., or the identification code 120 is located in the electronic display screen, and the electronic display screen is set in the first light guide part 1121. The area of ​​the identification code 120 is smaller than the area of ​​the first light guide part 1121. The identification code 120 is set on the side of the first light guide part 1121 facing the collection cavity 111a, that is, the identification code 120 is located in the collection cavity 111a. When the identification code 120 is set on the side of the first light guide part 1121 facing away from the collection cavity 111a, the first light guide part 1121 is a transparent light guide plate, which is convenient for the collection component 130 to collect the preset information of the identification code 120.

[0063] Take the example that the identification code 120 is set on the side of the first light guide 1121 facing the collection chamber 111a. The light-transmitting member 113 can seal the first opening 1111, and the first light guide 1121 can seal the second opening 1112, so that the collection chamber 111a is in a relatively closed environment. The identification code 120 is set on the side of the first light guide 1121 facing the collection chamber 111a, and the identification code 120 will not be damaged by running water or dust, thereby protecting the identification code 120. In addition, the identification code 120 is located in the collection chamber 111a, and the user cannot identify and take out the identification code 120, thereby improving the safety of the smart vending machine 10. The area of ​​the identification code 120 is smaller than the area of ​​the first light guide portion 1121, that is, at least part of the first light guide portion 1121 is not provided with the identification code 120, so that the remaining part of the first light guide portion 1121 not provided with the identification code 120 can be used to guide light into the collection cavity 111a, thereby illuminating the identification code 120, so as to facilitate the collection component 130 to collect the identification code 120. At the same time, it is convenient for the collection component 130 to collect the identification code 120 through the light-transmitting member 113.

[0064] In some embodiments, please refer to Figure 2 The second light guide portion 1122 is a light guide plate. The light guide plate is fixed or integrally formed on the edge of the first light guide portion 1121, or the light guide plate is disposed on the door assembly 101, and the light emitting surface of the light guide plate is coupled with the light incident surface of the first light guide portion 1121.

[0065] The first light source assembly 103 is disposed in the door assembly 101 or the receiving cavity 1021a of the smart vending cabinet 10. When the second light guide portion 1122 is a light guide plate, the light guide plate can extend into the door assembly 101 through the opening 101b, and is used to guide the light of the first light source assembly 103 in the door assembly 101 to the first light guide portion 1121, or to guide the light of the first light source assembly 103 in the receiving cavity 1021a of the smart vending cabinet 10 to the first light guide portion 1121, and the light emitting surface of the light guide plate is coupled with the light incident surface of the first light guide portion 1121, so that the light guide plate can be used to guide the light emitted by the first light source assembly 103 of the smart vending cabinet 10 into the collection cavity 111a through the light guide plate and the first light guide portion 1121.

[0084] The present application also provides an identification method, which is used in the identification device 100 or the smart vending cabinet 10 as described above. Fig.16 , Fig.16 : is a flow chart of the identification method provided by this application. The identification method provided by this application includes:

[0085] Step B11: Determine whether the information collected by the collection component 130 conforms to preset information that matches the information carried by the identification code 120 .

[0086] When it is detected that the door assembly 101 enters the open state, the smart vending cabinet 10 starts the selling state, and the camera assembly (not shown) in the smart vending cabinet 10 obtains the user's shopping video or picture and monitors the commodity status, thereby preventing the theft of the commodities in the smart vending cabinet 10 and improving security. At the same time, the acquisition assembly 130 is turned on to collect the information of the identification code 120, and the processor is used to determine whether the information collected by the acquisition assembly 130 meets the preset information matching the information carried by the identification code 120.

[0087] If the processor determines that the information collected by the collection component 130 meets the preset information that matches the information carried by the identification code 120, step B12 is executed.

[0088] Step B12: Determine whether the door assembly 101 is in a closed state.

[0089] In some embodiments, please refer to Fig.15 The smart vending cabinet 10 further includes a locking mechanism 104. The locking mechanism 104 is used to close the door assembly 101. The locking mechanism 104 can be disposed between the box 102 and the door assembly 101 of the smart vending cabinet 10. The specific structure of the locking mechanism 104 is not limited in the embodiment of the present application.

[0090] After the processor determines that the information collected by the collection component 130 meets the preset information that matches the information carried by the identification code 120, it further determines that the door body component 101 is in a closed state.

[0091] If the processor determines that the information collected by the collection component 130 does not conform to the preset information that matches the information carried by the identification code 120, step B13 is executed.

[0092] Step B13: Determine whether the body component 101 is in the open state.

[0093] After the processor determines that the information collected by the collection component 130 does not conform to the preset information that matches the information carried by the identification code 120, it further determines that the door body component 101 is in the open state.

[0094] After the step of determining that the door assembly 101 is in the closed state, that is, after executing step B12, step B14 is also included.

[0095] Step B14: End the selling state of the smart vending cabinet 10 and enter the settlement state.

[0096] In some embodiments, the processor includes a settlement unit.
