Specific implementation manner

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 4 , in the embodiment of the present invention, an intelligent positioning charging cabinet unlocked by face recognition includes a charging cabinet 1. A camera acquisition module 2 is installed at the top of the end face of the charging cabinet 1. A touch display screen module 3 is embedded and installed below the camera acquisition module 2 on the end face of the charging cabinet 1. A plurality of charging bins 4 are embedded and installed below the touch display screen module 3 on the end face of the charging cabinet 1. An RFID reader / writer 5 is installed at the top of the charging bin 4 and penetrates into the inner cavity of the charging bin 4. Connecting frames 6 extending below the charging bin 4 are installed on both sides of the RFID reader / writer 5. A synchronous locking mechanism extending below the RFID reader / writer 5 is installed inside the RFID reader / writer 5. A pushing mechanism extending into the inner cavity of the charging bin 4 is installed at the tail end of the charging bin 4. Damping mechanisms are installed inside the top plate and the bottom plate of the charging bin 4.

[0020] In this embodiment: When the mobile phone of the person who needs to charge is completely turned off and the person needs to rent a power bank in the charging cabinet 1, at this time, the person stands in front of the charging cabinet 1 and touches the touch display screen module 3. For example, click "Rent" on the touch display screen module 3, check the corresponding liability statement, and then click "Confirm". At this time, the camera acquisition module 2 operates to take a picture of the face of the person who needs to rent, collect the face image of the person who needs to rent, and convert the collected optical signal into an electrical signal and transmit it to the processing terminal. The processing terminal performs processing such as grayscale conversion, noise reduction, and light normalization on the collected picture to improve the picture quality and reduce the influence of factors such as light on subsequent recognition. And using the built-in algorithm of the terminal, extract picture features, such as: the position, contour, and proportion of facial features, etc. These information form a feature vector, which can represent the unique information of this face;

[0021] After the image is processed and feature extracted, the terminal sends an electrical signal to the controller, and the controller controls a synchronous locking mechanism to unlock. After the synchronous locking mechanism is unlocked, the pushing mechanism located on the same charging compartment 4 is reset to push out the power bank inside the charging compartment 4. It should be noted that: the charging compartment 4 is generally equipped with a sensing mechanism (such as an infrared sensor, which can identify whether there is a power bank in the charging compartment 4 and feed back the information to the controller) to avoid misoperation of the controller. Secondly, before the controller controls the synchronous locking mechanism to unlock the power bank, the RFID reader 5 identifies the RFID installed on the top of the power bank and binds the pop-up power bank to the recorded facial information;

[0022] After the user finishes charging, he touches the "Return" on the display module 3. At this time, the operating system pays the QR code and pays the rental fee. After the payment is completed, the user inserts the rented power bank into the empty charging compartment 4. At this time, the RFID reader 5 recognizes the returned power bank and unbinds the power bank from the facial recognition information. If the renter fails to pay, the data will be transmitted to the background after the device recognizes it, forming a record for prosecution and collection of payment.

[0023] Please refer to Figure 2 , Figure 3 and Figure 4 The synchronous locking mechanism includes a receiving groove 13 opened inside the end plates on both sides, the internal sliding connection of the receiving groove 13 is limited to the block 7, the outer side of the limit block 7 is fixedly installed with a guide rod 15, and a C-shaped frame 17 is fixedly installed between the vertical plate portion of the connecting frame 6 and the outer side of the charging bin 4. The end of the guide rod 15 away from the limit block 7 passes through the C-shaped frame 17 and is slidably connected to the C-shaped frame 17. A connecting spring 16 is abutted between the C-shaped frame 17 and the limit block 7, and the connecting spring 16 is sleeved on the guide rod The outer periphery of 15, the synchronous unlocking mechanism also includes an iron limit block 19 fixedly mounted on the end of the guide rod 15 away from the limit block 7, an electromagnet 20 is fixedly mounted on the vertical plate portion of a C-shaped frame 17, a slide groove 18 extending along the width direction of the charging bin 4 is provided on the bottom plate of the iron limit block 19, and a rack 8 extending to the bottom of the charging bin 4 is fixedly mounted on the bottom end of the iron limit block 19, a gear 9 is meshed between the two racks 8, and the gear 9 is connected to the internal rotation of the charging cabinet 1 through a rotating shaft.

[0024] In this embodiment: After successfully recognizing the face, the controller controls the electromagnet 20 to be energized. The energized electromagnet 20 generates a magnetic suction force to attract one of the corresponding iron limit blocks 19. The iron limit block 19 slides under the magnetic suction force and pulls the connected guide rod 15 to slide. The guide rod 15 pulls the connected limit block 7 to move synchronously. At this time, the connecting spring 16 is compressed. At the same time, the moving iron limit block 19 drives the connected rack 8 to move. The rack 8 can drive the other rack 8 to move synchronously in the opposite direction through the gear 9, realizing the synchronous opposite movement of the two limit blocks 7. The limit blocks 7 are separated from the corresponding slots on the power bank housing. At this time, the pushing mechanism resets and pushes the power bank outward.

[0025] Please refer specifically to Figure 3 and Figure 4 , the pushing mechanism includes a push plate 10 slidably connected to the inner wall of the charging bin 4. The tail end of the push plate 10 is integrally formed with a sliding rod 11 protruding outward. The sliding rod 11 penetrates to the outside of the charging bin 4. A return spring 12 is abutted between the tail end of the push plate 10 and the inner wall tail end of the charging bin 4. One end of the sliding rod 11 located outside the charging bin 4 is integrally formed with a limit protrusion.

[0026] In this embodiment: After the synchronous locking mechanism releases the lock, at this time, the return spring 12 resets and pushes the push plate 10 to reset outward. The push plate 10 pushes the power bank outward, and one end of the power bank can be moved out of the inside of the charging bin 4.

[0027] Please refer specifically to Figure 4 , the damping mechanism includes connection grooves 21 opened in the top and bottom interiors of the charging bin 4. The inner walls of the connection grooves 21 are slidably connected with dampers 14 up and down. One end of the two dampers 14 penetrates into the inner cavity of the charging bin 4, and one end of the damper 14 located in the inner cavity of the charging bin 4 is in a hemispherical structure. A compression spring 22 is fixedly installed between one end of the damper 14 located inside the connection groove 21 and the inner wall of the connection groove 21.

[0028] In this embodiment: During the process of the power bank being pushed out, the hemispherical end of the damper 14 applies a resistance to the top and bottom of the outward-moving power bank under the thrust of the compression spring 22, avoiding the problem that the power bank is ejected too much and falls to the ground.

[0029] Please refer specifically to Figure 3 , one end of the limit block 7 penetrating into the inner cavity of the charging bin 4 is formed with a pressure-receiving inclined surface, and the pressure-receiving inclined surface is inclined outward toward the opening direction of the charging bin 4.

[0030] In this embodiment: In this design method, when returning the charging board, the power bank can squeeze the pressure-receiving inclined surface of the limit block 7 to realize the movement of the limit block 7, so as to smoothly insert the power bank.

[0031] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, making equivalent substitutions or changes should be covered within the protection scope of the present invention.
