The invention is provided with a telescopic driving component 4 below the drawer 3, which is used for driving the drawer 3 to automatically slide back and forth. The telescopic driving assembly 4 comprises a driving piece 5 (such as a speed reducing motor), a synchronous pulley 7, a tension pulley 11 and a synchronous belt 12, the driving piece 5 (the speed reducing motor) is fixedly connected with a motor fixing seat 6, and the motor fixing seat 6 is connected with the cabinet body 1 and forms rigid connection with each other; the motor output shaft of gear motor connects synchronous pulley 7, is equipped with synchronous belt 12 on synchronous pulley 7, and the other end dress of synchronous belt 12 is on take-up pulley 11, and take-up pulley 11 is fixed on take-up pulley fixing base 13, and take-up pulley fixing base 13 passes through the screw connection with cabinet body 1. The drawer control connecting piece 10 on the synchronous belt 12 is fixedly connected with the drawer 3. Under the driving of the driving part 5, the synchronous belt 12 rotates around the synchronous belt pulley 7 and the tension pulley 11 to drive the drawer 3 on the synchronous belt 12 to complete movement, so that the telescopic movement in the cabinet 1 is realized.

As a preferred embodiment, a toothed pressing plate 9 of the synchronous belt is further provided in this example to limit the position of the synchronous belt 12, so as to ensure the stability and reliability of the transmission.

As a preferred embodiment, the present example further has a waist-shaped adjustable opening on the structure of the tension pulley holder 13, so that it can tension the timing belt 12 to a proper position and lock with a screw.

As a preferred embodiment, a guide rail 2 for completing extension and retraction is further disposed on two sides of the drawer 3, one side of the guide rail 2 is connected to the drawer 3, and the other end is connected to the cabinet 1, so as to ensure that the drawer 3 can only slide along one direction (e.g. front-back or left-right direction).

In this instance, the storage cabinet with the automatically retractable drawer can be composed of a plurality of drawers, and the size, the floor height and the inner space of the drawers are not limited. The number of the drawers 3 in the cabinet body 1 is not limited, telescopic guide rails are arranged on two sides of each drawer 3, one side of each guide rail is connected to the corresponding drawer, and the other end of each guide rail is connected to the cabinet body, so that the drawers can only slide back and forth.

In the specific application example, each drawer 3 is provided with an independent telescopic driving assembly 4, and the opening and the closing of any cabinet door are independently controllable.

In a specific application example, two ends of the synchronous pulley 7 and the tension pulley 11 are both provided with limit switches 8, and the switch positions of the drawer 3 are determined by controlling the triggering of the drawer control connecting piece 10 on the limit switches 8; when an external force acts on the drawer 3 and needs to be forcibly pulled open, the limit switch 8 at one end of the synchronous pulley 7 detects a disconnection signal, and the driving piece 5 can immediately electrically close the cabinet door on the cabinet body 1.

The work flow of the whole telescopic assembly is as follows:

the driving piece 5 (a speed reducing motor) is fixedly connected with the motor fixing seat 6, and the motor fixing seat 6 is connected with the cabinet body 1 to form rigid connection; the motor output shaft of gear motor connects synchronous pulley 7, is equipped with synchronous belt 12 on synchronous pulley 7, and the other end dress of synchronous belt 12 is on take-up pulley 11, and take-up pulley 11 is fixed on take-up pulley fixing base 13, and take-up pulley fixing base 13 passes through the screw connection with cabinet body 1. Further, the tensioning wheel fixing seat 13 is provided with an adjustable waist-shaped opening, so that the tensioning synchronous belt 12 can be tensioned to a proper position and locked by a screw. The drawer control connecting piece 10 on the synchronous belt 12 is fixedly connected with the drawer 3.

The positive and negative rotation of the speed reducing motor drives the synchronous belt 12 to move back and forth and simultaneously drives the drawer 3 to move back and forth together to realize the opening and closing functions of the drawer 3, and both ends of the synchronous belt wheel 7 and the tensioning wheel 11 are provided with the limit switches 8. The switch position of the drawer 3 is determined by controlling the triggering of the drawer control connecting piece 10 to the limit switch 8. When external force acts on the drawer 3 and needs to be forcibly pulled open, the limit switch 8 at one end of the synchronous belt wheel 7 detects a disconnection signal, and the speed reduction motor can immediately power on the cabinet door on the closed cabinet body 1 to ensure that the cabinet door is always in a controllable state.

In specific application, the invention can control the speed reducing motor in a wireless mode such as Bluetooth, network and the like so as to complete automatic control of the drawer 3, and can also control the drawer in a mode of linkage with the cabinet body 1.

In specific application, the invention can be applied to ground fixed storage cabinets and logistics cabinets, and can also be applied to intelligent logistics equipment such as unmanned vehicles and unmanned aerial vehicles. By adopting the design of the invention, the safety problem and the reliability problem in the driving without closing the door can be avoided.
