[0026] Combination Figure 1-4 As shown, a horizontal unmanned intelligent vending refrigerator with automatic door opening and closing comprises:

[0027] The cabinet body 1 is a horizontal refrigerator cabinet body 1, the top surface of which is provided with an opening, and a slide groove 11 is provided on the inner side wall of the opening, a glass door 2 is installed inside the slide groove 11, and a connecting portion 3 is provided at one end of the glass door 2;

[0028] The protection component 4 is installed inside the connecting part 3, and is mainly used to monitor the distance between the glass door 2 and the inner wall of the cabinet 1, and to monitor the arms of the purchaser during the closing process;

[0029] The door locking assembly 5 is an automatic door locking device of the whole equipment, which is mainly used to close the glass door 2 automatically after the customer finishes shopping to prevent the cold air from leaking;

[0030] The controller 7 is used to control the core of the protection component 4 and the door locking component 5, and can adopt Siemens 200 smart small PLC controller or 1200 small PLC controller.

[0031] Specifically, in the present embodiment, two slide grooves 11 are provided on the same side wall and are spaced apart from each other, so the glass door 2 should also be provided with two pieces and spaced apart from each other, such as a general horizontal refrigerator structure.

[0032] In addition, a mounting groove 12 is provided on one side of the top surface of the cabinet 1, and a cover plate 13 is provided on the mounting groove 12. The mounting groove 12 should be connected with the slide groove 11 on one side, and the end of the connecting part 3 is directly inserted into the mounting groove 12 along the slide groove 11. At the same time, a sealing strip or a sealing block should be properly installed on the side wall of the glass door 2 so that it can be adapted and combined with the slide groove 11 and ensure its smooth sliding.

[0033] Two sets of door lock assemblies 5 are arranged inside the installation groove 12, and each set of door lock assemblies 5 includes a door lock 51, a transmission shaft 52 and a drive motor 53, wherein the door lock 51 is arranged near the end of the installation groove 12, and is used to cooperate with the connecting part 3 to lock the glass door 2. The door lock 51 adopts a right-angle structure, for example Figure 3 As shown, an electric telescopic rod is vertically arranged on the top surface of the right-angled mounting plate, and a through hole is penetrated through the top surface of the connecting part 3. The electric telescopic rod can be fully inserted into the through hole, thereby completing the limit clamping, so that the glass door 2 is completely locked.

[0034] The transmission shaft 52 is horizontally arranged inside the slide groove 11, and passes through the bottom of the connecting part 3, and both ends are rotatably connected to the end faces of the slide groove 11 respectively. At the same time, a bevel gear is provided on the end of the transmission shaft 52 facing the middle of the cabinet 1. The driving motor 53 is arranged on the inner wall of the mounting groove 12, and a transmission gear is installed on its output end, and the transmission gear and the bevel gear are meshed with each other.

[0035] The screw transmission structure mentioned above is only one of the transmission methods, and its main purpose is to drive the glass door 2 to move horizontally. Therefore, based on this purpose, a pulley structure, a chain plate transmission structure, etc. can also be used. As long as they can achieve the same purpose, they can be used interchangeably.

[0036] A plurality of mounting holes are provided on the end face of the connection part 3 facing the inner wall of the cabinet 1, and a protection component 4 is installed based on this structure. The protection component 4 consists of a plurality of pressure sensors 41 and two distance meters 42. The pressure sensor 41 can adopt any one of the models such as G1 / 4A (BSP), 1 / 4NPT, SAE 7 / 16-20 UNF, 4×G1 / 4 (BSP), G3 / 8, etc., and is installed on the side wall of the connection part 3 so that its surface is flush with the side wall of the connection part 3; the distance meter 42 adopts the SW-DB100 laser distance meter 42.

[0037] In actual operation, the protective component 4 detects the distance between the connecting part 3 and the side wall of the cabinet 1 through the distance meter 42, thereby transmitting the information to the controller 7. After the controller 7 determines the distance it needs to move, it controls the drive motor 53 to start. The drive motor 53 drives the transmission shaft 52 to rotate and forces the connecting part 3 to move along the slide groove 11, until the side wall of the connecting part 3 is in contact with the inner wall of the cabinet 1.

[0038] During this process, a safety distance is set inside the rangefinder 42. When the measured distance is higher than the safety distance, the pressure sensor 41 detects pressure and stops the drive motor 53 immediately, waiting for a certain period of time before continuing to work. If the measured distance is lower than the safety distance, the work is continued until the connecting portion 3 fits the side wall of the cabinet 1. The safety distance should be greater than the width of the purchaser's arm to ensure that the self-locking structure will not cause pinching during shopping, thereby improving the safety of its use.

[0039] At the same time, in order to facilitate the monitoring of internal items, a hemispherical camera 6 should be set on the cover plate 13. There are two cameras 6 in total, which are arranged close to the two ends of the cabinet 1 respectively. They are mainly used to monitor the items sold during shopping, and then transmit the information to the shopping system of the cabinet 1 (the system should adopt the same system as the internal system of the existing vending machine) so that shoppers can make convenient payments. At the same time, the merchant's QR code should be posted on the top surface. After the shopper scans the code, the controller 7 will adopt the above opposite driving method to drive the cabinet door to open for shopping. After shopping, the cabinet door is closed and the information collected by the camera 6 is used for quick settlement.

[0040] In addition, a display screen 8 is provided at a corner of the surface of the cabinet 1 , and the display screen is connected to a thermometer inside the cabinet 1 and is used to display the temperature inside the cabinet 1 in real time.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solution recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solution from the technical solution of the embodiments of the utility model.
