A drive assembly for rotating the table 10 and chair 13 is connected inside the vending machine body 1. The drive assembly includes an output shaft 6 and a gear set. The gear set includes a first gear 7, a second gear 8, and a third gear 11.

[0025] The output shaft 6 is equipped with a first gear 7, which meshes with a second gear 8. The second gear 8 is equipped with a rotating shaft 9, and a table 10 is mounted on the rotating shaft 9. The second gear 8 is meshed with a third gear 11, and a rotating shaft 12 is mounted on the third gear 11. Two chairs 13 are mounted on the rotating shaft 12. In this setup, the vending machine body 1 serves as the main structure of the entire device, bearing and protecting the internal components, and providing the mounting base for the table 10 and chair 13. The table 10 provides a flat surface for users to place items or for dining and resting, while the chair 13 is for users to sit on when resting. The drive assembly is responsible for providing power and realizing mechanical transmission to rotate the table 10 and chair 13, achieving the unfolding and storage functions. The output shaft 6 drives the first gear 7 to rotate. The gear set changes the direction and magnitude of the force through the meshing transmission between the gears, realizing the synchronous rotation of the table 10 and chair 13. The first gear 7 is mounted on the output shaft 6, transmitting the rotation of the output shaft 6 to the second gear 8. The second gear 8 meshes with the first gear 7 and the third gear 11, transmitting power to the rotating shaft 9 to drive the table 10 to rotate on one hand, and to the third gear 11 on the other hand. The third gear 11 meshes with the second gear 8, transmitting power to the rotating shaft 12 to drive the chair 13 to rotate on the other hand.

[0026] like Figures 1 to 5As shown in the specific embodiment, a connecting rod 4 is connected inside the vending machine body 1, and a motor 5 is connected to the end of the connecting rod 4. An output shaft 6 is installed on the motor 5. In this configuration, the connecting rod 4 connects the vending machine body 1 and the motor 5, serving to fix the position of the motor 5 and ensure the stable operation of the motor 5. The motor 5, as the power source of the entire drive assembly, converts electrical energy into mechanical energy and outputs rotational power, which drives the entire drive assembly to operate through the output shaft 6. The output shaft 6 outputs the rotation of the motor 5, providing rotational power to the first gear 7, and is a key component for transmitting motor power to the gear set.

[0027] like Figures 1 to 5 As shown, furthermore, multiple sets of connecting blocks 14 are connected to the vending machine body 1, and rotating shafts 9 and 12 are rotatably mounted in the multiple sets of connecting blocks 14 respectively. In this configuration, the connecting blocks 14 are fixedly installed in the vending machine body 1, providing support points for the rotating shafts 9 and 12, enabling them to rotate smoothly on them and ensuring the stability of the table 10 and chair 13. One end of the rotating shaft 9 is assembled in the connecting block 14, and the other end is mounted on the table 10. Driven by the second gear 8, the table 10 rotates around its axis. One end of the rotating shaft 12 is assembled in the connecting block 14, and the other end is mounted on the chair 13. Driven by the third gear 11, the chair 13 rotates around its axis.

[0028] like Figures 1 to 5 As shown, a slide groove 16 is provided on the vending machine body 1, a guide rod 17 is installed in the slide groove 16, a slider 18 is slidably installed on the guide rod 17, a support rod 19 is hinged to the slider 18, and a support block 20 is hinged to the end of the support rod 19. The support block 20 is connected to the bottom of the chair 13. In this configuration, the slide groove 16 is provided on the vending machine body 1 to provide an installation position for the guide rod 17 and to restrict the movement trajectory of the slider 18, so that it can only slide in the direction of the slide groove 16. The guide rod 17 is installed in the slide groove 16 to provide sliding guidance for the slider 18 and ensure the linearity of the slider 18's movement. The slider 18 slides on the guide rod 17, and the support block 20 at the bottom of the chair 13 is connected to the guide rod 17 through the hinged support rod 19. When the chair 13 is rotated to unfold or folded for storage, the support block 20 at the bottom of the chair 13 is connected to the guide rod 17. The support rod 19 slides on the guide rod 17 during movement. One end of the support rod 19 is hinged to the slider 18, and the other end is hinged to the support block 20. When the chair 13 is unfolded, it extends as the slider 18 slides, providing additional support to the chair 13 and enhancing its stability and load-bearing capacity. When the chair 13 is folded, it retracts as the slider 18 slides in the opposite direction. The support block 20 is connected to the bottom of the chair 13 and is hinged to the support rod 19, transferring the support force of the support rod 19 to the chair 13 and assisting in the stable support of the chair 13.

[0029] like Figures 1 to 5As shown, the vending machine body 1 has multiple square slots 15 on its side wall, through which the table 10 and chair 13 pass. In this configuration, the square slots 15 are located on the side wall of the vending machine body 1, providing a channel for the table 10 and chair 13 to unfold and fold, allowing the table 10 and chair 13 to rotate smoothly and achieve the functions of folding and unfolding.

[0030] like Figures 1 to 5 As shown, a rain shelter 2 is installed on the top of the vending machine body 1, and multiple support feet 3 are provided at the bottom of the vending machine body 1. In this configuration, the rain shelter 2 provides rain protection for users using the table 10 and chair 13, preventing them from being affected by rain during use and increasing their comfort. The support feet 3 are located at the bottom of the vending machine body 1, providing stable support for the vending machine body 1, allowing the entire device to be placed stably on the ground and ensuring the stability of the device in various environments.

[0031] The implementation principle of the automatic folding table and chair of a vending machine in this embodiment is as follows: The user scans the QR code on the vending machine with their mobile phone to complete the payment. The payment information is processed by the QR code payment control module. After successful payment, the module sends a start signal to the motor 5 connected to it to start the table and chair unfolding process. When the human body sensor installed near the table and chair area does not detect a human body signal within a preset time, the QR code payment control module sends a reverse signal to the motor 5 to start the table and chair folding process. After receiving the unfolding start signal, the motor 5 starts working, and its output shaft 6 rotates, driving the first gear 7 mounted on it to rotate synchronously. The first gear 7 meshes with the second gear 8, driving the second gear 8 to rotate. Since the second gear 8 is equipped with a rotating shaft 9, the table is mounted on the rotating shaft 9. The second gear 8 rotates, causing the rotating shaft 9 to drive the table 10 to rotate and unfold around the axis of the rotating shaft 9. At the same time, the second gear 8 meshes with the third gear 11, driving the third gear 11 to rotate. The third gear 11 is equipped with a rotating shaft 12, on which two chairs 13 are mounted. Thus, the rotation of the third gear 11 causes the rotating shaft 12 to drive the chairs 13 to rotate and unfold around the axis of the rotating shaft 12. While unfolding, the slider 18 slides along the guide rod 17. After the table 10 and chairs 13 are unfolded, the support rod 19 and the support block 20 provide auxiliary support for the chairs 13, ensuring the stability and safety of the table and chairs during use. When the motor 5 receives the retraction signal and reverses, the components operate in the opposite order, and the table and chairs are folded and stored.
