[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this utility model.

[0025] refer to Figures 1-5 The shelf body 1 includes four support frames 11 and an upper placement plate 12 and a lower placement plate 13 that are slidably connected to the four support frames 11. Goods can be placed on both the upper placement plate 12 and the lower placement plate 13. A partition 121 is fixedly connected in the middle of the upper placement plate 12, and large goods can be placed on both sides of the partition 121.

[0026] With reference to Figures 1-5 The sliding cavity 111 is formed in the support frame 11, and the two sides of the upper placing plate 12 and the lower placing plate 13 are fixedly connected with sliding rods 14 which extend into the sliding cavity 111. A sliding groove is formed in the side wall of the sliding cavity 111 for the sliding of the sliding rods 14. The center of the sliding cavity 111 is fixedly connected with an elastic driving block 112, and the elastic driving block 112 and the sliding rods 14 are fixedly connected with springs 113. The elastic force of the springs 113 is directed to the surface of the elastic driving block 112, and the springs 113 can pull the upper placing plate 12 and the lower placing plate 13 to move towards each other. In the natural state, the distance between the upper placing plate 12 and the lower placing plate 13 is equal to the thickness of the elastic driving block 112 plus the height of the two springs 113 in the natural state.

[0027] With reference to Figures 1-5 The driving assembly 2 is arranged between the two support frames 11 and can drive the upper placing plate 12 and the lower placing plate 13 to move. The driving assembly 2 comprises driving rollers 21 fixedly arranged on the upper placing plate 12 and the lower placing plate 13 respectively, and a driving motor 22 fixedly connected to the surface of the support frame 11. The output end of the driving motor 22 is fixedly connected with a driving screw 221, and the driving screw 221 is slidingly connected with a special-shaped block 222 which is in contact with the driving rollers 21. The driving screw 221 is driven to rotate by the rotation of the driving motor 22, and the special-shaped block 222 is driven to move along the length direction of the driving screw 221. The special-shaped block 222 is isosceles trapezoidal and has two inclined surfaces. The driving rollers 21 are in contact with the inclined surfaces of the special-shaped block 222 to realize the synchronous movement of the upper placing plate 12 and the lower placing plate 13 in two opposite directions with the same distance. The driving rollers 21 and the corresponding upper placing plate 12 and lower placing plate 13 move synchronously. The driving assembly 2 further comprises connecting rods 23 fixedly connected to one side of the upper placing plate 12 and the lower placing plate 13 respectively. The end of the connecting rod 23 is fixedly connected with a connecting block 231, and the bottom of the connecting block 231 is fixedly connected with a linkage rod 232. The driving roller 21 is rotationally connected to the bottom of the linkage rod 232. The linkage rod 232 is an elastic telescopic rod which can buffer and further reduce the distance between the upper placing plate 12 and the lower placing plate 13 when the two driving rollers 21 are in contact without the action of the special-shaped block 222. The driving assembly 2 further comprises a driving limiting ring 24 fixedly connected to the end of the driving screw 221. The diameter of the driving limiting ring 24 is greater than the cross-sectional diameter of the driving screw 221, so as to limit the maximum displacement distance of the special-shaped block 222 on the driving screw 221.

[0028] With reference to Figures 1-5Several infrared ranging sensors 3, which are fixed to the irregularly shaped block 222, are slidably arranged between the upper placement plate 12 and the lower placement plate 13. They can measure the distance between the bottom surface of the upper placement plate 12 and the top surface of the lower placement plate 13. The driving components 2 are symmetrically arranged, and a ranging height rod 31 is fixedly connected between the two irregularly shaped blocks 222. Several infrared ranging sensors 3 are fixedly connected to the ranging height rod 31, which enables the irregularly shaped block 222 to move synchronously, thereby measuring the distance at different points. This prevents the goods from blocking the measurement readings of the infrared ranging sensors 3 and improves the accuracy of the distance measurement.

[0029] The working principle of this mechanism is as follows: When using this automatic adjusting shelf, the spring 113 is first in its natural state, at which point the upper placement plate 12 is at a height where large goods can be placed manually. When the surface of the upper placement plate 12 is full of large goods, the drive motor 22 is started. The drive motor 22 drives the drive screw 221 to rotate, causing the irregular block 222 to move along the length of the drive screw 221. When the irregular block moves between the two contacting drive rollers 21, its inclined surface will push open the space between the two drive rollers 21, causing the two drive rollers 21 to rotate and move away from each other. At this time, the two connecting rods 23 linked to the two drive rollers 21 will also move away from each other, which will cause the distance between the upper placement plate 12 and the lower placement plate 13 to increase. The staff determines the required space size. When the infrared ranging sensor 3 detects the upper placement plate 12... Once the distance between the upper and lower placement plates 12 and 13 reaches the specified distance, the drive motor 22 will automatically stop rotating. At this point, the distance between the upper and lower placement plates 12 and 13 will be the required distance, and items can be placed on the surface of the lower placement plate 13. If it is necessary to increase the distance between the upper and lower placement plates 12 and 13 during the placement process, the drive motor 22 will be restarted. Select the reading from the infrared ranging sensor 3 that is directly above the top surface of the lower placement plate 13, and then adjust the distance between the upper and lower placement plates 12 and 13 again. After the goods are placed, keep the drive motor 22 stopped to complete the loading process of large goods. When the goods are taken away or unloaded, the drive motor 22 will be reversed, causing the irregular block 222 to move away from the two drive rollers 21. Under the action of the spring 113, the upper and lower placement plates 12 and 13 will return to their initial state.

[0030] The above embodiments are used to further illustrate the present invention, but do not limit the present invention to these specific embodiments. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be understood as being within the protection scope of the present invention.
