A level measuring instrument 35 is fixedly connected to the front end of the movable mounting plate 31. The sponge shock-absorbing plate 37 absorbs shocks from falling goods, preventing fragile items such as glass bottles from directly colliding with the storage box 34 and causing damage. The pressure sensor 36 monitors pressure changes in real time. When a sudden increase in pressure is detected and quickly stabilizes, the lifting device lowers the storage box 34, preventing the vending machine's lifting device from falling without acquiring goods. The level measuring instrument 35 monitors the horizontal status of the device, ensuring that the storage box 34 remains level at all times.
[0029] The storage unit 3 also includes limiting grooves 38, an electric telescopic rod 39, and sliding limiting grooves 310. Four limiting grooves 38 are formed at the four corners of the upper end of the movable mounting plate 31. The electric telescopic rod 39 is fixedly connected to the inner side of each limiting groove 38. Four sliding limiting grooves 310 are formed on the left and right sides of the movable mounting plate 31. The limiting grooves 38 limit the installation of the electric telescopic rod 39, ensuring that the storage box 34 remains horizontal when the electric telescopic rod 39 rises, facilitating the stable falling of goods into the storage box 34.
[0030] The lifting sensor 4 also includes a second motor 41, a threaded rod 42, and limiting posts 43. Four limiting posts 43 are fixedly connected to the left and right sides of the inner front end of the vending machine body 1. The inner side of the sliding limiting groove 310 is slidably connected to the limiting posts 43. Limiting posts 43 are rotatably connected to the upper and lower sides of the left end of the vending machine body 1. The second motor 41 is fixedly connected to the upper end of the vending machine body 1, and the output shaft of the second motor 41 is fixedly connected to the threaded rod 42. The second motor 41 drives the threaded rod 42 to rotate, causing the movable mounting plate 31 to move up and down.

[0033] The working principle of the intelligent lifting platform device for an automatic vending machine provided by this utility model is as follows: A movable mounting plate 31 supports a limiting mounting block 32, which limits the storage box 34. The storage box 34 is used to store goods that fall from the vending machine. A motor 33 drives the storage box 34 to shift. When the movable mounting plate 31 descends to the bottom, the motor 33 drives the storage box 34 forward, making it convenient for customers to retrieve goods from the dispensing slot. A sponge shock-absorbing plate 37 dampens the falling goods, preventing fragile items such as glass bottles from directly colliding with the storage box 34 and causing damage. A pressure sensor 36 monitors pressure changes in real time. When a sudden increase in pressure is detected and quickly stabilizes, the lifting device lowers the storage box 34, preventing the vending machine's lifting device from falling without retrieving goods. A level measuring instrument 35 monitors the horizontal state of the device, ensuring that the storage box 34 always remains horizontal. The limiting groove 38 limits the installation of the electric telescopic rod 39, ensuring that the storage box 34 remains horizontal when the electric telescopic rod 39 rises, facilitating the stable drop of goods into the storage box 34. Motor 41 drives the threaded rod 42 to rotate, causing the movable mounting plate 31 to move up and down. The limiting post 43 and the sliding limiting groove 310 limit the movable mounting plate 31, achieving precise lifting and lowering of the device. The laser emitter 44 emits a laser, and the laser receiver 46 receives the signal to determine the stopping position of the movable mounting plate 31, ensuring that the goods accurately fall into the storage box 34. During the descent of the movable mounting plate 31, the infrared detector 45 emits infrared light downwards while the infrared receiver 47 receives it, thereby detecting whether there are any obstacles below, such as a customer's hand, to prevent crushing accidents during retrieval. The cargo compartment mounting plate 2 is used to install the goods vending pusher, and the baffle 5 serves as the customer retrieval port, facilitating customers to retrieve their purchased goods.
