[0032] Reference Figure 1-5The figure shows a preferred embodiment of the present invention.

[0033] An intelligent shelf that prevents tires from being deformed when left at rest due to being too large includes a controller and multiple frames. The frames are provided with a hollow layer, and the hollow layer is provided with multiple partition plates 500. The multiple partition plates 500 are arranged in sequence and spaced apart along the width direction of the hollow layer, and a placement area 504 for placing tires 100 is formed between adjacent partition plates 500; the front end of the placement area 504 is arranged open to form a front end opening, the lower part of the placement area 504 forms a lower area 502, and the upper part of the placement area 504 forms an upper area 501.

[0034] The tire 100 can be placed in the placement area 504 through the front opening, and the tire 100 in the placement area 504 can also be removed from the placement area 504 through the front opening.

[0035] The front end of the lower area 502 is provided with a lower roller 200 that is driven to rotate by a lower motor and abuts against the outer periphery of the tire 100. The rear end of the upper area 501 is provided with two upper rollers 300 that are driven to rotate by an upper motor and abut against the outer periphery of the tire 100. The two upper rollers 300 are respectively movably connected to the two partition plates 500.

[0036] The two upper rollers 300 are arranged facing each other at intervals, and along the height direction of the placement area 504, the two upper rollers 300 are staggered in an up-down manner; the lower roller 200 rotates in the same direction as the two upper rollers 300; the two upper rollers 300 are located above the lower area 502, and are arranged obliquely relative to the lower roller 200 respectively.

[0037] In this way, three contact positions are formed between the two upper rollers 300 and the lower roller 200 and the tire 100 , which facilitates the cooperation between the lower roller 200 and the two upper rollers 300 to drive the tire 100 to rotate in the placement area 504 .

[0038] An arc-shaped rail groove 503 is provided on the partition plate 500, and the arc-shaped rail groove 503 extends from the upper area 501 toward the lower area 502, and is curved at the same arc as the outer periphery of the tire 100; a movable seat is connected to the arc-shaped rail groove 503, and the movable seat is connected to a movable motor that drives the movable seat to move along the arc-shaped rail groove 503, and the upper motor is arranged on the movable seat.

[0039] A support seat 400 is provided at the rear end of the lower area 502. The support seat 400 has a support surface 402 arranged toward the tire 100 and abutting against the outer periphery of the tire 100. The support surface 402 is curved along the circumferential arc of the tire 100. The support seat 400 is connected to a support motor 401 that drives the support seat 400 to tilt toward or away from the tire 100.

[0040] When the tire 100 is placed in the placement area 504, the lower roller 200 and the support surface 402 tilt from bottom to top to support the lower part of the tire 100, and the two upper rollers 300 laterally support the rear part of the tire 100, and the front part of the tire 100 is exposed at the front opening; when the support motor 401 drives the support seat 400 to tilt and move toward the tire 100 a set distance, the support surface 402 presses the tire 100 to leave the placement area 504 through the front opening.

[0041] By arranging the support seat 400, the support surface 402 is bent along the circumferential arc of the tire 100, which can cooperate with the lower roller 200 to support the tire 100. The support surface 402 has a larger contact area, which reduces the deformation of the tire 100. In addition, the tire 100 can be pressed and driven out of the placement area 504 by the tilting movement of the support seat 400.

[0042] After the tire 100 has been stationary in the placement area 504 for a set time, the controller controls the lower motor and the upper motor to rotate at a fixed time. When the upper motor drives the upper roller 300 to rotate, the moving motor drives the moving seat and the upper roller 300 to move in an arc along the arc track groove 503, and the moving direction of the upper roller 300 is opposite to the rotation direction of the upper roller 300. The upper roller 300 and the lower roller 200 drive the tire 100 to rotate in place by a set angle.

[0043] The moving direction of the upper roller 300 is opposite to the rotation direction of the upper roller 300, which can increase the friction between the upper roller 300 and the tire 100. In the process of driving the tire 100 to rotate, keeping the upper roller 300 moving in the opposite direction along the circumference of the tire 100 can drive the tire 100 to rotate more quickly and conveniently.

[0044] The above-mentioned intelligent shelf for preventing tires from excessive static deformation has the tire 100 placed in the placement area 504, and the support surface 402 and the lower roller 200 are used to support the lower part of the tire 100, and the two upper rollers 300 are used to support the rear part of the tire 100, forming multi-position support for the tire 100; the controller regularly controls the two upper rollers 300 and the lower roller 200 to rotate in the same direction, and the mobile motor drives the two upper rollers 300 to move along the arc-shaped rail groove 503, which can quickly drive the tire 100 to rotate in situ in the placement area 504 to a set angle, thereby preventing the tire 100 from being stationary in the placement area 504 for too long and causing large static deformation.

[0045] Of course, as the moving direction of the upper roller 300 on the arc-shaped track 503 changes, the rotation directions of the upper roller 300 and the lower roller 200 also change accordingly, as long as the rotation direction is kept opposite to the moving direction.

[0046] In this embodiment, multiple shelves are connected to a transmission frame, and transmission chains with an up and down circuitous transmission arrangement are provided on both sides of the transmission frame; multiple shelves are stacked up and down, and both sides of the shelves are connected to the transmission chains respectively, and the transmission chains drive the shelves to move up and down on the transmission frame.

[0047] In this way, a multi-layer shelf arrangement can be formed, which is beneficial to the space utilization for placing the tires 100, and the shelves can be moved up and down by the action of the transmission frame and the transmission chain, making it easy to take and place the tires 100 on the shelves.

[0048] In this embodiment, a swing arm is provided on both sides of the support surface 402, the lower end of the swing arm is hinged on the side of the support surface 402, the upper end of the swing arm is arranged to be tilted upward, and a free roller is provided on the upper end of the swing arm; when the tire 100 is placed in the placement area 504, the free roller abuts against the side of the tire 100.

[0049] When the tire 100 is placed in the placement area 504, the tire 100 can be clamped and positioned laterally by the opposing clamping of the swing arms, and the free rollers abut against the side surfaces of the tire 100 without affecting the original rotation of the tire 100.

[0050] The swing arms on either side of the support surface 402 are arranged in an offset manner to form a clamping path. The lower ends of the swing arms are connected to torsion springs that drive the swing arms to swing back toward the clamping path. In this way, tires 100 of varying widths can be laterally positioned by clamping the swing arms in opposite directions.

[0051] In this embodiment, the support surface 402 is recessed downward to form a plurality of recessed grooves, which are arranged throughout the support surface 402. A lower ball 600 is provided in the recessed groove for rolling. The upper portion of the lower ball 600 is exposed outside the recessed groove, and an elastic layer 601 is filled between the lower portion of the lower ball 600 and the bottom of the recessed groove. When the support surface 402 tilts to support the lower portion of the tire 100, the lower ball 600 is pressed by the tire 100 and retracts inward into the recessed groove, and the elastic layer 601 is compressed.

[0052] When the outer periphery of the tire 100 is pressed against the support surface 402, the lower ball 600 is sunken inward like a sunken groove, and the lower ball 600 that is not pressed is in its original convex state. In this way, the lower ball 600 that is not sunken can laterally position the side of the tire 100. When tires 100 of different widths are placed in the placement area 504, the lower ball 600 can be used to align the side for lateral positioning, and the lower ball 600 is arranged in a rolling manner and will not affect the original rotation of the tire 100.

[0053] Secondly, the lower ball bearings 600 can form multi-position abutment against the tire 100, thereby increasing the contact area with the tire 100, reducing the force on a single position of the tire 100, and reducing the static deformation of the tire 100.

[0054] In this embodiment, the two sides of the recessed groove are respectively recessed to form a plurality of side holes 602. When the elastic layer 601 is compressed, the two sides of the elastic layer 601 are respectively embedded in the side holes 602. When the elastic layer 601 recovers its deformation, the two sides of the elastic layer 601 are separated from the side holes 602. The provision of the side holes 602 provides sufficient space for the compression deformation of the elastic layer 601, thereby facilitating the elastic deformation of the elastic layer 601.

[0055] The recessed groove forms a groove opening on the supporting surface 402, and the diameter of the groove opening is smaller than the diameter of the lower ball 600; the bottom of the elastic layer 601 is fixed to the bottom of the recessed groove, and the top of the elastic layer 601 is covered with a non-deformable hard layer 603, and the lower part of the lower ball 600 abuts against the hard layer 603.

[0056] After the lower ball 600 is rolled and placed in the recessed groove, the lower ball 600 is prevented from being separated from the recessed groove. By setting the hard layer 603, the elastic layer 601 maintains the contact area with the lower ball 600 unchanged during the elastic deformation process, and can realize the overall arc-shaped upper and lower compression deformation. When the elastic layer 601 is in a compressed state, the smoothness of the rotation of the lower ball 600 is maintained.

[0057] In this embodiment, the outer surface of the upper roller 300 and the outer surface of the lower roller 200 are both provided with mesh grooves arranged in a mesh shape, and the mesh grooves are filled with elastic mesh strips 201. The bottom of the mesh grooves is recessed downward to form a plurality of bottom grooves 202; the two sides of the mesh strips 201 are respectively fixedly connected to the inner side walls of the mesh grooves, and the bottom of the mesh strips 201 movably abuts the bottom of the mesh grooves, and the top of the mesh strips 201 extends out of the mesh grooves.

[0058] When the upper roller 300 and the lower roller 200 abut against the outer circumference of the tire 100, the mesh strip 201 is pressed by the tire 100 and deformed downward. The bottom of the mesh strip 201 is embedded in the bottom groove 202, and the top of the mesh strip 201 is retracted into the mesh groove.

[0059] By arranging the mesh strips 201, the outer surfaces of the upper roller 300 and the lower roller 200 can be more firmly in contact with the outer periphery of the tire 100, and a multi-position contact is formed. Combined with the pattern on the outer periphery of the tire 100, the tire 100 can be driven to rotate in place more conveniently and quickly.

[0060] In this embodiment, the partition plate 500 is provided with a plurality of ventilation holes connected to the placement area 504, and the plurality of ventilation holes are arranged throughout the partition plate 500. In this way, a plurality of tires 100 are placed in the plurality of placement areas 504 of the shelf, and can be ventilated through the plurality of ventilation holes.

[0061] In this embodiment, the outer end of the upper roller 300 is connected to the upper motor, and the inner end of the upper roller 300 extends to the middle of the placement area 504, forming an inner end portion abutting the middle of the tire 100; a follower shaft 301 that rotates synchronously with the upper roller 300 extends outward from the center of the inner end portion, and a plurality of follower plates 302 extend outward from the outer periphery of the follower shaft 301, and the plurality of follower plates 302 are arranged around the circumference of the follower shaft 301 at intervals.

[0062] The outer end of the follower plate 302 has an abutment strip that abuts against the outer periphery of the tire 100. The abutment strip is arranged in an arc shape and is provided with a plurality of upper balls that abut against the outer periphery of the tire 100. The outer end of the follower shaft 301 is extended with a side strip 303, and the side strip 303 is provided with side balls 304. The side balls 304 abut against the side of the tire 100.

[0063] Since the outer end of the upper roller 300 extends to the middle of the placement area 504, it only abuts half of the outer circumference of the tire 100. In order to maintain the balance of the upper roller 300 when driving the tire 100 to rotate in place, when the tire 100 is rotating, through the synchronous rotation of multiple follower plates 302, the abutment strips of the multiple follower plates 302 alternately abut the outer circumference of the tire 100, further enhancing the driving force of the tire 100 to rotate in place.

[0064] Secondly, by arranging the side strips 303 and by having the side balls 304 abut against the side surfaces of the tire 100 , the tire 100 can be positioned and limited laterally during its rotation in situ.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
