Description

Technical Field

[0001] The present invention belongs to the technical field of campus payment, and in particular relates to a face recognition payment device for campus payment. Background Art

[0002] Face payment is a new payment method based on artificial intelligence, machine vision, 3D sensing, big data and other technologies. It has the advantages of being more convenient, safer and providing a better experience. With the continuous advancement of science and technology, face recognition payment has gradually become popular, greatly facilitating people's lives.

[0003] On campus, the traditional campus card payment method has many defects, such as the need to recharge the balance regularly, and the card is prone to loss and theft. Therefore, in order to solve the above problems, most campuses have begun to introduce facial recognition payment devices and promote their application in places such as campus cafeterias.

[0004] However, after searching and combining the installation and debugging experience of actual campus face payment equipment, it is found that the current face payment device is poorly compatible with the campus use environment. Most face payment devices are placed on the countertop, but in canteens and other places, in order to increase the table dining area, reduce oil pollution, facilitate cleaning, and facilitate face recognition payment, the device is usually tied and installed on the canteen window guardrail. However, this installation method has problems such as slow installation speed and unstable installation, and it is easy to shake during operation and affect recognition. In addition, the face recognition payment device is equipped with a larger display screen for feedback of face acquisition information, but the existing device lacks protection function, and it is not convenient to provide isolation protection for the display screen when idle. Therefore, it is urgent to improve the existing face recognition payment device for campus payment and provide a face recognition payment device for campus payment. Summary of the invention

[0005] The purpose of the present invention is to provide a face recognition payment device for campus payment with reasonable design, simple structure, quick and stable installation, conforming to the actual use environment of the campus, and having isolation and protection functions, in order to solve the problems existing in the prior art.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A face recognition payment device for campus payment, which includes a bracket, a face recognition screen and a card reading area. The top of the bracket is rotatably installed with a face recognition screen. The middle outer wall at the bottom end of the face recognition screen is provided with a card reading area. A protection component is installed at the top end of the face recognition screen. The middle outer wall at the rear end of the bracket is fixedly installed with an operation panel, and the operation panel is electrically connected to the face recognition screen through an electric wire. The rear outer wall at the bottom end of the bracket is fixedly provided with an upper clamping plate, and a second rubber pad is adhered to the bottom end surface of the upper clamping plate. A clamping and positioning component is arranged directly below the upper clamping plate, and a pushing component is arranged below the clamping and positioning component. The rear outer wall at the bottom of the bracket is provided with three vertical grooves in an inverted "pin" shape. Vertical shafts are fixed on the inner sides of the left and right vertical grooves, and a trapezoidal lead screw is installed by a bearing in the inner side of the middle vertical groove. The bottom end of the trapezoidal lead screw penetrates through the bottom of the bracket and extends to the outside thereof.

[0008] As a preferred implementation manner, a positioning bolt is installed by threading on the outer wall of the right side at the top of the bracket, and barbs are fixedly connected to the outer walls on the left and right sides at the bottom end of the face recognition screen through bolts.

[0009] As a preferred implementation manner, the protection component includes a storage box, a volute spring, a horizontal shaft, a protection curtain and a counterweight rod. The storage box is fixedly installed at the top of the face recognition screen. A horizontal shaft is installed in the middle position inside the storage box through a volute spring. The two ends of the protection curtain are respectively adhered and fixed to the outer walls of the horizontal shaft and the counterweight rod.

[0010] As a preferred implementation manner, the protection curtain forms a winding structure outside the horizontal shaft.

[0011] As a preferred implementation manner, the clamping and positioning component includes a lower clamping plate, a first convex block, a limiting rod, a support spring and a T-shaped rod. First convex blocks are symmetrically fixed on the left and right sides of the end of the lower clamping plate close to the bracket. A through groove structure is formed in the middle of the lower clamping plate, and a limiting rod is fixedly arranged inside the through groove structure. A support spring is arranged on the outer side of the limiting rod, and a T-shaped rod is slidably sleeved on the outer side of the limiting rod. The vertical section of the T-shaped rod is clamped and slidably located in the through groove structure in the middle of the lower clamping plate.

[0012] As a preferred implementation manner, the two first convex blocks are respectively slidably sleeved on the outer sides of the two vertical shafts. A first rubber pad is adhered to the side of the top of the T-shaped rod close to the bracket, and fixing columns are symmetrically fixed on the left and right sides at the bottom of the vertical section of the T-shaped rod.

[0013] As a preferred implementation manner, the pushing component includes a concave frame, a second convex block and an inclined groove. A second convex block is fixed at the end of the concave frame close to the bracket. The second convex block is threadedly sleeved on the outer side of the trapezoidal lead screw. Inclined grooves are formed on the outer walls on the left and right sides of the concave frame.

[0014] As a preferred embodiment, one end of the two fixing columns away from the T-shaped rod is respectively guided and slidably located inside the two inclined grooves.

[0015] As a preferred implementation, the T-shaped rod forms a horizontal sliding structure on the outer side of the limiting rod through a concave frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] In the scheme of the present invention:

[0018] The upper and lower clamping plates are respectively located at the upper and lower sides of the campus cafeteria window railings, and then the trapezoidal screw rod is manually rotated. At this time, under the action of the supporting spring, the pushing assembly and the clamping positioning assembly can be relatively stationary and synchronously raised along the vertical axis. After the lower and upper clamping plates clamp the window railings, the lower clamping plate is stationary. As the trapezoidal screw rod continues to rotate to control the second protrusion and the concave frame to continue to rise, the inclined grooves on the outer walls of the left and right sides of the concave frame can be used to push the fixing column to overcome the elastic force of the supporting spring, and the fixing column drives the T-shaped rod to move forward along the limit rod until it is tightly fitted with the window railing, so that the device can be quickly and stably installed, and can be applicable to window railings of different specifications. There is no need to use traditional methods such as tapes and ropes to tie the device to the railings. The device is easy to install and more stable to use.

[0019] By using the first rubber pad and the second rubber pad, the friction between the upper clamping plate and the T-shaped rod and the railing of the campus cafeteria window can be increased to prevent the device from sliding along the railing. In addition, the face recognition screen is rotatably installed on the top of the bracket, which is convenient for adjusting according to the window height and obtaining the face. A certain margin is left in the length of the wire to prevent the face recognition screen from being too tight and breaking when rotating.

[0020] When the device is idle after get off work in the cafeteria, the counterweight rod can be manually pulled to pull the protective curtain out of the storage box. During this process, the horizontal axis will rotate and the scroll spring will accumulate force. The counterweight rod will be pulled to the bottom of the facial recognition screen and positioned through the barb, so that the protective curtain can cover the surface of the facial recognition screen, which can provide good isolation and protection for the facial recognition screen, avoiding scratches and dust or oil adhesion. When in use, you only need to disengage the counterweight rod from the barb, and the scroll spring can be used to control the automatic rotation of the horizontal axis to rewind the protective curtain, which is easy to operate.

[0033] The embodiments described below are only some of the embodiments of the present invention and do not represent all the embodiments consistent with the present invention. Now, in conjunction with the accompanying drawings, the exemplary embodiments are described as follows:

[0034] like Figure 1-9As shown in the figure, the face recognition payment device for campus payment of the present invention includes a bracket 1, a face recognition screen 2 and a card reading area 3. The top of the bracket 1 is rotatably installed with the face recognition screen 2. The middle outer wall at the bottom end of the face recognition screen 2 is provided with a card reading area 3. A protection component 5 is installed at the top end of the face recognition screen 2. The middle outer wall at the rear end of the bracket 1 is fixedly installed with an operation panel 6. The operation panel 6 is electrically connected to the face recognition screen 2 through an electric wire 7. The rear outer wall at the bottom end of the bracket 1 is fixedly provided with an upper clamping plate 10. A second rubber pad 11 is adhered to the bottom end face of the upper clamping plate 10. A clamping and positioning component 8 is arranged directly below the upper clamping plate 10. A pushing component 9 is arranged below the clamping and positioning component 8. Three vertical grooves 12 are formed in an inverted "pin" shape on the rear outer wall at the bottom of the bracket 1. Vertical shafts 13 are fixed on the inner sides of the left and right vertical grooves 12. A trapezoidal lead screw 14 is installed by a bearing on the inner side of the middle vertical groove 12. The bottom end of the trapezoidal lead screw 14 penetrates through the bottom of the bracket 1 and extends to the outside thereof.

[0035] On the basis of the above structure, a positioning bolt 15 is threadedly installed on the outer wall of the right side at the top of the bracket 1. Hooks 4 are fixedly connected to the outer walls of the left and right sides at the bottom end of the face recognition screen 2 through bolts.

[0036] In this embodiment, by setting the positioning bolt 15, it is convenient to position the angle of the face recognition screen 2 at the top of the bracket 1, facilitating face acquisition and recognition.

[0037] On the basis of the above structure, the protection component 5 includes a storage box 51, a volute spring 52, a horizontal shaft 53, a protection curtain 54 and a counterweight rod 55. The storage box 51 is fixedly installed at the top of the face recognition screen 2. A horizontal shaft 53 is installed in the middle position inside the storage box 51 through a volute spring 52. The two ends of the protection curtain 54 are respectively adhered and fixed to the outer walls of the horizontal shaft 53 and the counterweight rod 55.

[0038] On the basis of the above structure, the protection curtain 54 forms a winding structure on the outside of the horizontal shaft 53.

[0039] In this embodiment, when the device is idle, the protection curtain 54 can be pulled out from the storage box 51 and covered on the surface of the face recognition screen 2, which can play a good isolation and protection effect on the face recognition screen 2, avoiding both scratching and adhesion of dust or oil stains.

[0040] On the basis of the above structure, the clamping and positioning component 8 includes a lower clamping plate 81, a first convex block 82, a limiting rod 83, a support spring 84 and a T-shaped rod 85. The left and right sides of the end of the lower clamping plate 81 close to the bracket 1 are symmetrically fixed with first convex blocks 82. A through groove structure is formed in the middle of the lower clamping plate 81. A limiting rod 83 is fixedly arranged inside the through groove structure thereof. A support spring 84 is arranged on the outside of the limiting rod 83. A T-shaped rod 85 is slidably sleeved on the outside of the limiting rod 83. The vertical section of the T-shaped rod 85 is clamped and slidably located in the through groove structure in the middle of the lower clamping plate 81.

[0041] On the basis of the above structure, the two first protrusions 82 are respectively slidably mounted on the outside of the two vertical shafts 13, a first rubber pad 86 is bonded to the top of the T-shaped rod 85 close to the bracket 1, and a fixing column 87 is fixed symmetrically to the bottom of the vertical section of the T-shaped rod 85.

[0042] On the basis of the above structure, the pushing assembly 9 includes a concave frame 91, a second protrusion 92 and an oblique groove 93. The second protrusion 92 is fixed to one end of the concave frame 91 close to the bracket 1. The second protrusion 92 is threadedly sleeved on the outer side of the trapezoidal screw rod 14. The outer walls on both sides of the concave frame 91 are provided with oblique grooves 93.

[0043] On the basis of the above structure, the ends of the two fixing columns 87 away from the T-shaped rod 85 are respectively guided and slidably located inside the two inclined grooves 93 .

[0044] On the basis of the above structure, the T-shaped rod 85 forms a horizontal sliding structure on the outer side of the limiting rod 83 through the concave frame 91 .

[0045] In this embodiment, the trapezoidal screw rod 14 is manually rotated, and the pushing assembly 9 and the clamping positioning assembly 8 can be synchronously raised and relatively stationary under the action of the supporting spring 84. After the lower splint 81 contacts the window railing, as the trapezoidal screw rod 14 continues to rotate, the concave frame 91 can continue to rise. At this time, the inclined groove 93 can be used to squeeze and push the fixing column 87, overcome the elastic force of the supporting spring 84, and make the fixing column 87 drive the T-shaped rod 85 forward along the limiting rod 83 until it is tightly fitted with the window railing, which is convenient for the quick and stable installation of the device and can be applied to window railings of different specifications. There is no need to use traditional methods such as tape and rope to tie the device to the railing. The device is easy to install and more stable to use, which is more in line with the actual usage scenarios and environments of campus payment.

[0046] The working principle of the present invention is as follows:

[0047] When in use, firstly, the upper clamping plate 10 and the lower clamping plate 81 of the device are respectively located on the upper and lower sides of the campus cafeteria window railing, and the bracket 1 is made to contact and fit with the railing, and then the trapezoidal screw rod 14 can be manually rotated. At this time, under the support of the elastic force of the support spring 84, the pushing component 9 and the clamping and positioning component 8 can be synchronously moved up along the vertical axis 13 in a relatively static state. After the lower clamping plate 81 and the upper clamping plate 10 clamp the window railing, the lower clamping plate 81 is restricted and remains static. At this time, as the trapezoidal screw rod 14 continues to rotate, the second protrusion 92 and the concave block 92 can be controlled to move upward. When the concave frame 91 continues to rise, the inclined grooves 93 on the outer walls of the left and right sides of the concave frame 91 can be used to push the fixing column 87, which can overcome the elastic force of the support spring 84, and make the fixing column 87 drive the T-shaped rod 85 to move forward along the limit rod 83 synchronously until the top of the T-shaped rod 85 is tightly fitted with the window railing, so that the device can be quickly and stably installed on the cafeteria window railing, and can be effectively applied to cafeteria window railings of different specifications and sizes, and it is no longer necessary to use traditional methods such as tape and rope to tie the device to the railing. The device is easy to install and more stable to use;

[0048] When the device is idle after the canteen is off duty, the counterweight rod 55 can be manually pulled to pull the protective curtain 54 out of the storage box 51. During this process, the horizontal axis 53 will rotate and the spiral spring 52 will start to store force. After the counterweight rod 55 is pulled to the bottom of the facial recognition screen 2, it can be positioned by the left and right hooks 4, so that the protective curtain 54 can be stably unfolded and covered on the surface of the facial recognition screen 2, which can play a good isolation and protection effect on the facial recognition screen 2, and can avoid scratches and adhesion of dust or oil. When in use, it is only necessary to disengage the counterweight rod 55 from the hook 4, and the spiral spring 52 can be used to control the horizontal axis 53 to automatically rotate, so that the protective curtain 54 can be rewound and retracted, which is easy to operate.

[0049] It should be specially noted that this device is created to address and overcome the real defects existing in payment environments such as campus canteens. In this case, the facial recognition screen 2, operating panel 6 and wires 7 are all existing products. The specific internal structure and working principle are existing mature technologies and are not the key points of protection in this case, so they will not be described in detail.

[0050] The above are only preferred specific embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any equivalent changes, modifications, substitutions and variations made by technicians in this technical field based on the concept of the present invention through logical analysis, reasoning or limited experiments on the basis of the prior art should be within the scope of protection determined by the claims.
