Description

Technical Field

[0001] The invention belongs to the technical field of bookshelves, and in particular relates to a working method of a storage device. Background Art

[0002] Existing similar high-rise storage delivery racks are mostly installed in higher bookcases or shelves. The high-rise storage delivery rack is pulled out by a rocker mechanism and lowered at an angle set by the rocker mechanism. The high-rise storage delivery rack can be pushed up again to return to the cabinet with a set motion curve. This shortens the distance between the user and the cabinet, saves the time for the user to use a ladder to reach the height of the storage rack, and speeds up the speed of taking out and putting back.

[0003] The existing Chinese patent application number is 201110063449.9, and the Chinese patent document with the publication date of 2012.08.22 discloses a three-dimensional lifting bookshelf, including an outer frame, a lower book carrier, an upper book carrier, a lead screw, a wire rope, a winding wheel, a linear bearing guide, a worm wheel, and a worm. The lower book carrier and the upper book carrier are both installed in the outer frame, the worm seat is fixed on the outer frame, the lead screw is installed on the worm seat through the worm wheel and the worm, the lead screw is also connected to the upper book carrier, a linear bearing guide is installed between the lower book carrier and the outer frame, the winding wheel is installed on the linear bearing guide, two strands of the wire rope are both wound on the winding wheel, and the wire rope is fixedly connected to the lower book carrier, and the worm and the winding wheel are driven by a worm motor and a winding motor respectively. The invention can transport books which are difficult to take out at a high level to a more suitable height through a transmission device, thereby avoiding the potential safety hazard of needing to climb up to take out, and fully utilizing the space, greatly saving the floor space.

[0004] However, the invention is divided into an upper book carrier and a lower book carrier. If the upper book carrier is to be lowered, the lower book carrier must first be pushed inward along the linear bearing guide to make room for the lower position before the upper book carrier is lowered. The steps are complicated and the use is troublesome. Summary of the invention

[0005] The object of the present invention is to provide a working method of a storage device, which can flip down a storage rack at a higher level independently without affecting the storage racks at the lower level, and is simple and convenient to use.

[0006] To achieve the above-mentioned purpose, a working method of a storage device is provided, wherein the storage device is lifted and lowered by an intelligent lifting bookshelf, wherein the intelligent lifting bookshelf comprises a mounting frame and one or more lifting bookshelf devices arranged longitudinally along the mounting frame, wherein the lifting bookshelf device comprises a storage rack for placing books and articles, a rotating mechanism for lifting the storage rack, and a constant level mechanism for maintaining the storage rack in a horizontal state, wherein the rotating mechanism is located on both sides of the mounting frame, and the constant level mechanism is arranged on the rotating mechanism, and storage racks are arranged on the constant level mechanisms on both sides of the mounting frame; the constant level mechanism comprises a belt, a central axis rod, a driving gear, a driven gear, a constant level motor and a level sensor, wherein one end of the central axis rod is arranged on the side wall of the storage rack, and the other end of the central axis rod is provided with a driven gear, wherein the driving gear is meshed and connected with the driven gear, the belt is wound on the driving gear and the driven gear, the constant level motor is connected to the driving gear through a driving shaft, a sleeve is provided on the central axis rod, and the sleeve is movably sleeved on the central axis rod, and the sleeve is connected to the lifting component, and the specific steps are as follows:

[0007] (1) When picking up objects, the rotating mechanism rotates to drive the constant level mechanism and the rack connected to the constant level mechanism to rotate and descend; when it is not necessary to pick up objects, the rotating mechanism rotates to drive the constant level mechanism and the rack connected to the constant level mechanism to rotate and ascend;

[0008] (3.1) When the lifting assembly swings downward, it drives the central shaft rod to swing downward; when the lifting assembly swings upward, it drives the central shaft rod to swing upward;

[0009] (3.2) When the central axis is swinging downward, the rack will tend to tilt downward; when the central axis is swinging upward, the rack will tend to tilt upward;

[0010] (3.3) When the horizontal sensor located on the rack detects that the rack is tilting downward; When the horizontal sensor located on the rack detects that the rack is tilting upward;

[0011] (3.4) The level sensor sends control signals to the leveling motors on the left and right sides;

[0012] (3.51) When the storage rack tilts downward, the left constant level motor starts to drive the driving gear to rotate in the second direction, thereby driving the driven gear to rotate in the first direction; the right constant level motor starts to drive the driving gear to rotate in the second direction, thereby driving the driven gear to rotate in the first direction; the central shaft rod fixedly connected to the driven gear rotates in the first direction at the same time, and the storage rack fixedly connected to the central shaft rod rotates in the first direction at the same time, until the storage rack is restored to a horizontal state;

[0013] (3.52) When the rack is tilted upward, the left constant level motor starts to drive the driving gear to rotate in the first direction, and then drives the driven gear to rotate in the second direction; the right constant level motor starts to drive the driving gear to rotate in the first direction, and then drives the driven gear to rotate in the second direction; the central axis rod fixedly connected to the driven gear rotates in the second direction at the same time, and the rack fixedly connected to the central axis rod rotates in the second direction at the same time, until the rack returns to a horizontal state. With the above arrangement, the constant level mechanism and the rack connected to the constant level mechanism can be lowered or raised by rotating the rotating mechanism, and the higher racks can be flipped down and up separately without affecting the racks on the lower level. During the flipping process, the rack can be kept rising and falling smoothly. It is simple and convenient to use. The lifting assembly drives the central axis rod to swing downward while swinging downward. During the downward swinging process, the rack will tilt downward. Therefore, when the horizontal sensor on the rack detects that the rack is tilted downward, the horizontal sensor sends a control signal to the constant level motors on the left and right sides. Observe the left side of the bookshelf, the left constant level motor starts up and drives the driving gear to rotate clockwise, and then drives the driven gear to rotate counterclockwise. At the same time, the right constant level motor starts up and drives the driving gear to rotate clockwise, and then drives the driven gear to rotate counterclockwise. The central shaft rod fixedly connected to the driven gear rotates counterclockwise at the same time, and the storage rack fixedly connected to the central shaft rod rotates counterclockwise at the same time until the storage rack returns to a horizontal state, so that the storage rack remains in a horizontal state during the downward movement to prevent items on the storage rack from falling, and at the same time ensures that the high storage rack can be moved down alone without affecting the lower The structure of the bookshelf is simple and stable. The lifting assembly drives the central axis rod to swing upward while swinging upward. During the upward swing, the shelf will tilt upward. Therefore, when the horizontal sensor on the shelf detects that the shelf is tilted upward, the horizontal sensor sends a control signal to the constant level motors on the left and right sides. When viewed from the left side of the bookshelf, the constant level motor on the left starts to drive the driving gear to rotate counterclockwise, and then drives the driven gear to rotate clockwise. At the same time, the constant level motor on the right starts to drive the driving gear to rotate counterclockwise, and then drives the driven gear to rotate clockwise. The fixedly connected central axis rotates clockwise at the same time, and the storage rack fixedly connected to the central axis rotates clockwise at the same time until the storage rack returns to a horizontal state, so that the storage rack remains in a horizontal state during the upward movement to prevent items on the storage rack from falling; when the storage rack is in a horizontal static state, the constant level motor is in a locked state; and because the central axis is movably connected to the sleeve ring, the swing of the lifting assembly and the rotation of the central axis in the sleeve ring do not affect each other, and through the above method, when taking objects, only the rotating mechanism needs to rotate and the constant level mechanism needs to maintain a balanced state, and the method of use is simple.

[0014] Further, the rotating mechanism includes a rotating motor, a first bevel gear, a second bevel gear, a lifting assembly and a collar, connecting plates are provided on both sides of the mounting frame, the rotating motor is arranged on the outer side of the connecting plate, a base is provided on the inner side of the connecting plate, a connecting shaft is provided on the base, one end of the connecting shaft is fixedly connected to the base, the other end of the connecting shaft passes through the connecting plate, a first bevel gear is provided on the driving shaft of the rotating motor, a second bevel gear meshing with the first bevel gear is provided on the other end of the connecting shaft, and a lifting assembly is provided on the base;

[0015] Step (1) specifically includes:

[0016] (1.11) When picking up an object, the rotor of the rotating motor on the left drives the first bevel gear to rotate counterclockwise; the rotor of the rotating motor on the right drives the first bevel gear to rotate clockwise;

[0017] (1.12) The first bevel gear on the left rotates counterclockwise, driving the second bevel gear meshing with the first bevel gear to rotate clockwise; the first bevel gear on the right rotates clockwise, driving the second bevel gear meshing with the first bevel gear to rotate counterclockwise;

[0018] (1.13) The rotation of the second bevel gear on the left drives the connecting shaft to rotate clockwise, which in turn drives the base to rotate clockwise along the connecting shaft, and the base drives the lifting assembly to rotate clockwise; the rotation of the second bevel gear on the right drives the connecting shaft to rotate counterclockwise, which in turn drives the base to rotate counterclockwise along the connecting shaft, and the base drives the lifting assembly to rotate counterclockwise;

[0019] (1.21) When there is no need to pick up objects, the rotor of the rotating motor on the left drives the first bevel gear to rotate clockwise; the rotor of the rotating motor on the right drives the first bevel gear to rotate counterclockwise;

[0020] (1.22) The first bevel gear on the left rotates clockwise, driving the second bevel gear meshing with the first bevel gear to rotate counterclockwise; the first bevel gear on the right rotates counterclockwise, driving the second bevel gear meshing with the first bevel gear to rotate clockwise;

[0021] (1.23) The rotation of the second bevel gear on the left side drives the connecting shaft to rotate counterclockwise, which in turn drives the base to rotate counterclockwise along the connecting shaft, and the base drives the lifting assembly to rotate counterclockwise; the rotation of the second bevel gear drives the connecting shaft to rotate clockwise, which in turn drives the base to rotate clockwise along the connecting shaft, and the base drives the lifting assembly to rotate clockwise.

[0022] With the above arrangement, when it is necessary to flip the high storage rack down, observing from the front of the bookshelf, the rotor of the rotating motor on the left side drives the first bevel gear to rotate counterclockwise, and the counterclockwise rotation of the first bevel gear drives the second bevel gear meshing with the first bevel gear to rotate clockwise, and the rotation of the second bevel gear drives the connecting shaft to rotate clockwise. Since the connecting shaft and the base are fixedly connected, the base is driven to rotate clockwise along the connecting shaft. At the same time, the rotor of the rotating motor on the right side drives the first bevel gear to rotate clockwise, and the clockwise rotation of the first bevel gear drives the second bevel gear meshing with the first bevel gear to rotate counterclockwise, and the rotation of the second bevel gear drives the connecting shaft to rotate counterclockwise. Since the connecting shaft and the base are fixedly connected, the base is driven to rotate counterclockwise along the connecting shaft. Because the base is fixedly connected, the lifting assembly is fixedly connected to the base, thus, the clockwise rotation of the base on the left side drives the lifting assembly on the base to swing downward, and the counterclockwise rotation of the base on the right side drives the lifting assembly on the base to swing downward; similarly, when it is necessary When the lower storage shelf is flipped up, observing from the front of the bookshelf, the rotor of the rotating motor on the left side drives the first bevel gear to rotate clockwise, and the first bevel gear rotates counterclockwise to drive the second bevel gear meshing with the first bevel gear to rotate counterclockwise, and the rotation of the second bevel gear drives the connecting shaft to rotate counterclockwise. Since the connecting shaft and the base are fixedly connected, the base is driven to rotate counterclockwise along the connecting shaft. At the same time, the rotor of the rotating motor on the right side drives the first bevel gear to rotate counterclockwise, and the first bevel gear rotates counterclockwise to drive the second bevel gear meshing with the first bevel gear to rotate clockwise, and the rotation of the second bevel gear drives the connecting shaft to rotate clockwise. Since the connecting shaft and the base are fixedly connected, the base is driven to rotate clockwise along the connecting shaft. Because the base is fixedly connected, the lifting assembly is fixedly connected to the base, the base on the left side rotates counterclockwise to drive the lifting assembly on the base to swing upward, and the base on the right side rotates clockwise to drive the lifting assembly on the base to swing upward. The flipping mechanism has a simple structure and a fast flipping speed.

[0023] Furthermore, the lifting assembly includes a lifting motor and an electric telescopic rod, the lifting motor and the electric telescopic rod are arranged on the base, the telescopic motor controls the telescopic action of the electric telescopic rod, and the collar is connected to the tail of the electric telescopic rod;

[0024] The specific step (1) also includes:

[0025] (1.14) When the lifting assembly rotates and descends, the lifting motor controls the electric telescopic rod to extend;

[0026] (1.24) When the lifting assembly rotates and rises, the lifting motor controls the electric telescopic rod to retract.

[0027] With the above arrangement, when the lowered position of the storage rack at a higher level may be blocked by the storage rack at a lower level, the lifting motor drives the electric telescopic rod to extend, so that the storage rack can be lowered in a wider range of positions, thereby ensuring that the storage rack at a higher level will not conflict with the storage rack at a lower level; when the storage rack rises and returns to its original position, the lifting motor drives the electric telescopic rod to retract, and the storage rack returns to its original height, making it easier for people to observe the items on the storage rack.

[0028] Furthermore, a through hole is provided on the connecting plate, a bearing is provided in the through hole, and the other end of the connecting shaft passes through the bearing and extends to the outside of the connecting plate.

[0029] The above arrangement, by arranging the bearing, makes the rotation of the connecting shaft convenient and the structure is simple and reliable.

[0030] Furthermore, a guardrail is provided at the edge of the storage rack.

[0031] The above arrangement prevents items on the rack from falling by setting a guardrail, and the structure is simple and effective. Furthermore, before step (1), the method further includes step (1.1) receiving a user's gesture signal and voice signal through a voice and visual sensor, and if the voice signal or gesture signal is detected as a rack raising signal, the rack is controlled to perform a raising operation, and if the voice signal or gesture signal is detected as a rack lowering signal, the rack is controlled to perform a lowering operation.

[0032] The above settings, by setting up voice and visual sensors, can realize the reception of voice and gesture signals, so as to facilitate the judgment of whether to take the object or not, and then free the hands to complete the lifting and lowering of the storage rack, and the structure is simple and effective.

[0033] Furthermore, a controller is provided on the side of the installation frame, and more than two buttons are provided on the controller, and the buttons control each shelf accordingly.

[0034] The above settings use the controller as a backup for the voice vision sensor to control the lifting of the shelf, so as to prevent the lifting function of the shelf from being completed when there is a problem with the vision sensor.

[0035] Furthermore, a hanging pin groove is provided on the back of the mounting frame, and the hanging pin groove includes a middle rectangular groove and arc grooves located on both sides of the middle rectangular groove, the arc grooves are connected to the middle rectangular groove, and the arc grooves are arranged obliquely downward relative to the middle rectangular groove.

[0036] The above setting, by setting the hanging pin groove, can conveniently hang the installation frame on a wall or table with a hanging pin, saving space. The arc grooves on both sides provide a larger mounting area, and the middle rectangular groove determines the mounting direction. It is not easy to slide and has good stability after hanging.

[0045] The present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] like Figure 1-7 As shown, in this embodiment, a working method of a storage device is provided to realize the lifting of an intelligent lifting bookshelf, wherein the intelligent lifting bookshelf comprises a mounting frame 1 and one or more lifting bookshelf devices 2 arranged longitudinally along the mounting frame, wherein the lifting bookshelf device 2 comprises a storage rack 21, a rotating mechanism 3 and a constant level mechanism 4, wherein the rotating mechanism 3 is located on both sides of the mounting frame 1, and the constant level mechanism 4 is arranged on the rotating mechanism 3, and the storage rack 21 is arranged on the constant level mechanism 4 on both sides of the mounting frame 1; the rotating mechanism 3 comprises a rotating motor 31, a first bevel gear 32, and a second bevel gear Wheel 33, lifting cylinder lifting assembly 30 and collar, connecting plates 5 are provided on both sides of the mounting frame 1, the rotating motor 31 is arranged on the outer side of the connecting plate 5, a base 52 is provided on the inner side of the connecting plate 5, a connecting shaft 36 is provided on the base 52, one end of the connecting shaft 36 is fixedly connected to the base 52, the other end of the connecting shaft 36 passes through the connecting plate 5, a first bevel gear 32 is provided on the driving shaft of the rotating motor 31, a second bevel gear 33 meshing with the first bevel gear 32 is provided on the other end of the connecting shaft 36, and a lifting assembly 30 is provided on the base.

[0047] In this embodiment, the connecting plate 5 includes a first connecting plate 511 and a second connecting plate 512 vertically connected to the first connecting plate 511, the rotating motor 31 is fixed on the mounting frame 1, the first connecting plate 511 of the connecting plate 5 is fixed on the mounting frame, and the connecting shaft 36 passes through the second connecting plate 512 and is connected to the mounting seat 52.

[0048] A controller 7 is provided on the side of the mounting frame, and more than two buttons 71 are provided on the controller 7. The buttons 71 control each shelf accordingly. The controller 7 is used as a backup for the voice and visual sensor to control the lifting of the shelf, so as to complete the lifting function of the shelf when there is a problem with the visual sensor.

[0049] The constant level mechanism 4 includes a belt 40, a central shaft 41, a driving gear 43, a driven gear 42, a constant level motor 44 and a level sensor 45. One end of the central shaft 41 is arranged on the side wall of the storage rack 21, and the other end of the central shaft 41 is provided with a driven gear 42. The driving gear 43 is meshed and connected with the driven gear 42. The belt 40 is wound on the driving gear 43 and the driven gear 42. The constant level motor 44 is connected to the driving gear 43 through a driving shaft. A ring 37 is provided on the central shaft 41. The ring 37 is movably mounted on the central shaft 41, and the ring 37 is connected to the lifting assembly 30.

[0050] In this embodiment, there are three lifting bookshelf devices 2 , and the distance between two adjacent lifting bookshelf devices 2 is greater than the height of each lifting bookshelf device 2 when each lifting bookshelf device 2 is in a vertical state with respect to the installation frame 1 .

[0051] With the above arrangement, when the high storage rack 21 needs to be flipped down, when viewed from the front of the bookshelf, the rotor of the rotating motor 31 on the left side drives the first bevel gear 32 to rotate counterclockwise, and the counterclockwise rotation of the first bevel gear 32 drives the second bevel gear 33 meshing with the first bevel gear 33 to rotate clockwise, and the rotation of the second bevel gear 33 drives the connecting shaft 36 to rotate clockwise. Since the connecting shaft 36 and the base 52 are fixedly connected, the base 52 is driven to rotate clockwise along the connecting shaft 36. At the same time, the rotor of the rotating motor 31 on the right side drives the first bevel gear 32 clockwise. The first bevel gear 32 rotates clockwise to drive the second bevel gear 33 meshing with the first bevel gear 33 to rotate counterclockwise. The second bevel gear 33 rotates to drive the connecting shaft 36 to rotate counterclockwise. Since the connecting shaft 36 and the base 52 are fixedly connected, the base 52 is driven to rotate counterclockwise along the connecting shaft 36. Since the lifting assembly 30 is fixedly connected to the base 52, the base 52 on the left rotates clockwise to drive the lifting assembly 30 on the base 52 to swing downward, and the base 52 on the right rotates counterclockwise to drive the lifting assembly 30 on the base 52 The assembly 30 swings downward, and the lifting assembly 30 drives the central shaft 41 to swing downward while swinging downward. During the downward swinging process, the shelf 21 will tilt downward. Therefore, when the horizontal sensor 45 located on the shelf 45 detects that the shelf 21 tilts downward, the horizontal sensor 45 sends a control signal to the constant level motors 44 on the left and right sides. When viewed from the left side of the bookshelf, the constant level motor 44 on the left starts to drive the driving gear 43 to rotate clockwise, thereby driving the driven gear 42 to rotate counterclockwise. At the same time, the constant level motor 44 on the right starts to drive the driving gear 43 to rotate clockwise, thereby driving the driven gear 42 to rotate counterclockwise. The machine 44 starts to drive the driving gear 43 to rotate clockwise, which in turn drives the driven gear 42 to rotate counterclockwise. The central shaft 41 fixedly connected to the driven gear 42 rotates counterclockwise at the same time, and the rack 21 fixedly connected to the central shaft 41 rotates counterclockwise at the same time until the rack 21 returns to a horizontal state, so that the rack 21 remains in a horizontal state during the downward movement to prevent the items on the rack 21 from falling, and at the same time ensures that the high rack 21 can be moved down alone without affecting the rack 21 on the lower layer, and the structure is simple and stable.

[0052] Similarly, when the lower storage rack 21 needs to be flipped up, when viewed from the front of the bookshelf, the rotor of the rotating motor 31 on the left side drives the first bevel gear 32 to rotate clockwise, and the first bevel gear 32 rotates counterclockwise to drive the second bevel gear 33 meshing with the first bevel gear 33 to rotate counterclockwise, and the rotation of the second bevel gear 33 drives the connecting shaft 36 to rotate counterclockwise. Since the connecting shaft 36 and the base 52 are fixedly connected, the base 52 is driven to rotate counterclockwise along the connecting shaft 36. At the same time, the rotor of the rotating motor 31 on the right side drives the first bevel gear 32 to rotate counterclockwise, and the first bevel gear 32 rotates counterclockwise. The clockwise rotation drives the second bevel gear 33 meshing with the first bevel gear 33 to rotate clockwise, and the rotation of the second bevel gear 33 drives the connecting shaft 36 to rotate clockwise. Since the connecting shaft 36 and the base 52 are fixedly connected, the base 52 is driven to rotate clockwise along the connecting shaft 36. Since the lifting assembly 30 is fixedly connected to the base 52, the base 52 on the left side rotates counterclockwise to drive the lifting assembly 30 on the base 52 to swing upward, and the base 52 on the right side rotates clockwise to drive the lifting assembly 30 on the base 52 to swing upward, and the lifting assembly 30 swings upward at the same time. When the central axis 41 is driven to swing upward, the rack 21 will tilt upward during the upward swinging process. Therefore, when the horizontal sensor 45 located on the rack 45 detects that the rack 21 tilts upward, the horizontal sensor 45 sends a control signal to the constant level motors 44 on the left and right sides. When viewed from the left side of the bookshelf, the constant level motor 44 on the left starts to drive the driving gear 43 to rotate counterclockwise, thereby driving the driven gear 42 to rotate clockwise. At the same time, the constant level motor 44 on the right starts to drive the driving gear 43 to rotate counterclockwise, thereby driving the driven gear 42 to rotate clockwise. The central shaft 41 fixedly connected to the driven gear 42 rotates clockwise at the same time, and the rack 21 fixedly connected to the central shaft 41 rotates clockwise at the same time until the rack 21 returns to a horizontal state, so that the rack 21 remains in a horizontal state during the upward movement to prevent the items on the rack 21 from falling off; when the rack 21 is in a horizontal stationary state, the constant level motor 44 is in a locked state; and because the central shaft 41 is movably connected to the collar 37, the swing of the lifting assembly 30 and the rotation of the central shaft 41 in the collar 37 do not affect each other.

[0053] like Figure 3 , Figure 4 and Figure 7 As shown, the lifting assembly 30 includes a lifting cylinder 34 and an electric telescopic rod 35, and the lifting cylinder 34 and the electric telescopic rod are arranged on the base 52. The lifting cylinder 34 controls the telescopic action of the electric telescopic rod 35, and the collar 37 is connected to the tail of the electric telescopic rod 35.

[0054] like Figure 3As shown, the electric telescopic rod 35 includes an inner rod 351 and an outer rod 352, the inner rod 351 is located inside the outer rod 352 and the inner rod 351 is movably connected to the outer rod 352, the lower end of the outer rod 352 is fixedly connected to the upper end surface of the lifting cylinder 34, the lower end of the inner rod 351 is fixedly connected to the output end of the lifting cylinder 34, and the output end of the lifting cylinder 34 drives the inner rod 351 to extend and retract inside the outer rod 352; the collar 37 is provided at the other end of the inner rod 351.

[0055] With the above arrangement, the output end of the lifting cylinder 34 drives the inner rod 351 to move and retract inside the outer rod 352. The extension of the inner rod 351 allows the rack 21 to be lowered to a more appropriate height when it descends, and the shortening of the inner rod 351 allows the rack 21 to return to an appropriate height when it rises. The structure is simple.

[0056] When the lowered position of the storage rack 21 at a higher position may be blocked by the storage rack 21 at a lower level, the lifting cylinder 34 drives the electric telescopic rod 35 to extend, so that the storage rack 21 can be lowered in a wider range, ensuring that the storage rack 21 at a higher position will not conflict with the storage rack 21 at a lower level; when the storage rack 21 rises and returns to its original position, the lifting cylinder 34 drives the electric telescopic rod 35 to retract, and the storage rack 21 returns to its original height, making it easier for people to observe the items on the storage rack 21.

[0057] like Figure 3-4 As shown, a through hole 50 is provided on the connecting plate 5 , and a bearing 51 is provided in the through hole 50 . The other end of the connecting shaft 36 passes through the bearing 51 and extends to the outside of the connecting plate 5 .

[0058] The above arrangement, by providing the bearing 51, makes the rotation of the connecting shaft 36 convenient, and the structure is simple and reliable.

[0059] like Figure 5 As shown, a hanging pin groove 8 is provided on the back of the mounting frame, and the hanging pin groove 8 includes a middle rectangular groove 82 and arc grooves 81 located on both sides of the middle rectangular groove 82. The arc groove 81 is connected to the middle rectangular groove 82, and the arc groove 81 is arranged downwardly inclined relative to the middle rectangular groove 82. By setting the hanging pin groove 8, the mounting frame can be conveniently hung on a wall or table with a hanging pin to save space. The arc grooves on both sides provide a larger mounting area, and the middle rectangular groove 82 determines the mounting direction, which is not easy to slide and has good stability after hanging.

[0060] like Figure 2 As shown, a guardrail 22 is provided at the edge of the storage rack 21 .

[0061] The above arrangement prevents the articles on the storage rack 21 from falling by providing the guardrail 22, and the structure is simple and effective.

[0062] like Figure 2As shown, a voice and vision sensor 6 is provided at the lower end of the mounting frame 1. The voice and vision sensor 6 receives the user's gesture signals and voice signals and then controls the lifting and lowering of each shelf 21. In this embodiment, the voice and vision sensor 6 has the functions of both a voice sensor and a gesture recognition sensor. The voice and vision sensor is a prior art, and its specific working principle will not be repeated here.

[0063] like Figure 8 As shown, a working method of a storage device of the present invention comprises the following specific steps:

[0064] (1) When taking out an object, the rotating mechanism rotates to drive the constant level mechanism and the rack connected to the constant level mechanism to rotate and descend; when putting a book, the rotating mechanism rotates to drive the constant level mechanism and the rack connected to the constant level mechanism to rotate and ascend;

[0065] (2) When the shelf is lowered or raised, the shelf tends to tilt due to gravity and rotation factors. In this embodiment, the specific steps include: (3.1) the lifting component drives the central shaft rod to swing downward while swinging downward; the lifting component drives the central shaft rod to swing upward while swinging upward;

[0066] (3.2) When the central axis is swinging downward, the rack will tend to tilt downward; when the central axis is swinging upward, the rack will tend to tilt upward;

[0067] (3) When the rack tends to tilt, the constant level mechanism drives the rack to rotate in the direction opposite to the tilting direction to keep the rack in a balanced state. In this embodiment, step (3) specifically includes the following steps:
