Description

Technical Field

[0001] This application relates to the field of storage device technology, and in particular to a height-adjustable and rotatable storage rack suitable for patients with lumbar spine diseases, lower limb or joint diseases, and the elderly. This height-adjustable and rotatable storage rack can be directly applied to age-friendly home renovations and the construction of barrier-free living spaces for people with disabilities. Background Technology

[0002] Common storage solutions on the market include traditional fixed lockers, ordinary adjustable-height lockers, and some simple auxiliary storage shelves. Traditional fixed lockers have a fixed height, which means that elderly people and those with lumbar spine problems need to tiptoe or climb to retrieve items on higher shelves, easily leading to falls or excessive strain on the lower back and causing pain. Retrieving items on lower shelves requires bending over or squatting, which puts extra pressure on the lumbar spine, worsening their condition or causing discomfort. While ordinary adjustable-height lockers can change the storage height to some extent, the adjustment method often involves manually disassembling and reinstalling shelves, which is cumbersome and requires carrying items during adjustment, making it difficult for elderly people with weaker physical strength and those with lumbar spine problems to do independently. Furthermore, when items are placed deep inside the locker, users need to lean out to reach them, increasing the risk of imbalance and lower back injury.

[0003] Chinese utility model patent CN206423794U discloses a rotating and lifting locker, which includes a base, a central shaft, rails, and lockers. The base is disc-shaped, the central shaft is cylindrical, and bearings are provided on the outer side walls, fixed to the top surface of the base and coaxially arranged with the base. There are two rails, upper and lower, each rail including a bushing and a rail groove. The bushing is fitted onto the central shaft, the rail groove is vertically arranged, and its outer wall has a protrusion. There are two lockers, each including a slide rail and a cabinet body. The slide rail has a recessed hole on its side wall, and the cabinet body is a semi-cylindrical hollow body, open at the top and closed at the bottom. Although the locker disclosed in this patent document can rotate around the central shaft, thus changing the direction of the locker without moving the base, it allows the locker to rise or fall freely in the vertical direction via the rail groove and slide rail. The locking mechanism during the lifting process is achieved by the protrusion on the outer wall of the rail groove and the recessed hole on the outer wall of the slide rail. This structural design has the following defects:

[0004] 1. Users need to use considerable external force to overcome the interference fit between the protrusion and the concave hole to continue raising and lowering, which is not user-friendly for the elderly, children, and patients with lumbar spine diseases; at the same time, even a slight error in the size of the protrusion will cause "gear skipping" or "gear slipping", resulting in inaccurate positioning.

[0005] 2. The protrusions are only local point / line contacts. When subjected to repeated loads, they are prone to plastic deformation or wear, which can cause the slide rail to sink or become stuck. The edges of the recessed holes may also develop fatigue cracks due to impact, eventually losing their positioning function. Once the protrusions or recessed holes wear out, the cabinet may slip down instantly under the action of gravity, trapping hands or feet.

[0006] 3. Dust and oil stains entering the recesses will increase friction or cause jamming; when humidity changes cause changes in the size of the wood / plastic, the tightness of the fit between the protrusions and the recesses will change accordingly, further shortening the service life.

[0007] Therefore, existing lifting and rotating storage devices still have many shortcomings in application, and they cannot meet the needs of the elderly, patients with lumbar spine diseases, etc. There is an urgent need to propose a new technical solution to solve the problems existing in the current technology. Utility Model Content

[0008] This application provides a height-adjustable and rotatable storage rack to solve the problems of existing height-adjustable and rotatable storage devices being inconvenient to operate and use, and unfriendly to the elderly, children or patients with lumbar spine diseases.

[0009] To achieve the above objectives, this application provides the following technical solution:

[0010] This application provides a height-adjustable and rotatable storage rack, including a base with an inner cavity in which a drive motor is disposed. The output shaft of the drive motor passes vertically upward through the base and is fitted and fastened to the bottom end of a threaded rod vertically disposed on the base. One or more storage shelves are disposed on the threaded rod, each shelf including a shelf and multiple drawers mounted on the shelf. A mounting hole is formed in the middle of the shelf, and a bearing is installed in the mounting hole. The inner ring of the bearing is fixedly connected to the outer circumferential surface of a nut fitted and mounted on the threaded rod. A guide hole is formed on the side wall of the nut along its axial direction, and the nut is slidably connected to a limiting rod through the guide hole. The limiting rod is arranged parallel to the threaded rod. A lifting button for controlling the forward or reverse rotation of the drive motor is provided on the outer surface of the base.

[0011] Furthermore, in the above technical solution, a top plate is provided above the base and is arranged parallel to it. The top plate is connected to the base through a support frame. The top end of the threaded rod is rotatably connected to the top plate. A light source is provided on the plate surface of the top plate facing the base. A circuit assembly connected to the light source is provided in the inner cavity of the base. A switch button for controlling the light source to turn on and off is provided on the outer surface of the base.

[0012] Furthermore, the bottom of the limiting rod is fixedly connected to the base, and the top of the limiting rod is fixedly connected to the top plate.

[0013] Furthermore, the shelf includes a central connecting block and a plurality of mounting plates radially distributed along the outer periphery of the central connecting block. The central connecting block has a mounting hole for mounting the bearing. Between any two adjacent mounting plates, a mounting position for mounting a drawer is formed, a storage area for mounting shelves is formed, a hanging area for mounting hooks is formed, or an empty area for easy observation of the lower storage shelf is formed.

[0014] Furthermore, each of the storage shelves is provided with two empty areas, which are arranged opposite to each other, and a light strip is provided between the two mounting plates forming the empty areas.

[0015] Furthermore, the threaded rod is provided with a plurality of storage shelves at intervals, the radial dimension of the plurality of storage shelves gradually decreases from bottom to top, and the empty areas on any two adjacent storage shelves are staggered.

[0016] Furthermore, the two mounting plates forming the drawer mounting position are provided with slide rails, and the two sides of the drawer are provided with sliding connectors that are adapted to the slide rails. The drawer is provided with a handle.

[0017] Furthermore, the lifting button includes an up button and a down button. Operating the up button controls the drive motor to start rotating forward and drive the threaded rod to rotate clockwise, thereby causing the nut to move upward along the limit rod, thus moving the storage shelf upward. Operating the down button controls the drive motor to start rotating in reverse and drive the threaded rod to rotate counterclockwise, thereby causing the nut to move downward along the limit rod, thus moving the storage shelf downward.

[0018] Furthermore, the inner ring of the bearing is connected to the outer circumferential surface of the nut by a key, and the outer ring of the bearing is fixedly connected to the mounting hole on the shelf by a flange and bolts. The shelf can rotate around the center of the threaded rod under the push of an external force.

[0019] Compared with the prior art, this application has at least the following beneficial effects:

[0020] 1. The height-adjustable rotating storage shelf provided in this application uses a drive motor, threaded rod, nut, and limit rod to form a spiral lifting transmission system, which can drive the storage shelf to rise and fall smoothly. When using it, the user only needs to operate the lifting button with their foot to automatically adjust the height of the storage shelf. It is easy to operate and use, and the adjustment process does not require the user to exert physical strength, avoiding damage to the lumbar spine caused by tiptoeing, bending over, etc., which is friendly to the elderly, children, and patients with lumbar spine diseases. In addition, the storage shelf in this application is connected to the nut by bearings. The user only needs to manually apply pushing force to easily rotate the storage shelf. The user does not need to lean out or move, and can turn any item in the cabinet to the front by rotating the storage shelf, solving the problem of inconvenient access to items deep in traditional storage devices, allowing users to obtain all items from the same place.

[0021] 2. This application features a light source on the top panel, which can be a large-area soft light panel. The light is soft and has a wide coverage, providing basic lighting for the entire storage area. Especially when the ambient light is dim, it can illuminate the overall layout of each storage shelf, allowing users to have a clearer overall understanding of the storage situation inside the shelf. In addition, each storage shelf is equipped with a light strip, and the top light source can complement the local lighting of the storage shelf, further improving the convenience of retrieving items.

[0022] 3. The chassis of this application is equipped with a switch button for controlling the on / off of the top light source. Of course, the wiring of the light strips on each storage shelf can also be electrically connected to the switch button to control the on / off of all the lights on the storage shelf. The switch button is located on the base, so it can be a foot-operated switch button. The installation position is close to the ground, so the user does not need to bend over or touch it with their hands. They can easily control the light by simply kicking it with their toe. This foot-operated design provides a convenient operating experience, which is both labor-saving and practical, making lighting control more flexible and efficient, and making life more convenient for the elderly and patients with lumbar spine diseases.

[0023] 4. The threaded rod of this application is provided with multiple storage shelves. Each storage shelf can be equipped with one or more of the following: drawers, shelves, and hooks. This functional zoning can not only classify and store different types of items to reduce clutter, but also make frequently used small items readily accessible, further optimizing the space utilization and ease of use of the storage shelf.

[0024] 5. Each storage shelf in this application has two empty areas opposite each other, and each empty area is equipped with a light strip. The empty areas on any two adjacent storage shelves are staggered. The empty areas are designed to allow users to easily observe the items in the lower storage shelf, avoid obstructing their view, and make it easier for users to quickly find the target items.

[0025] 6. The drawers on the storage shelves in this application are designed without lids, which allows users to quickly browse the stored items and quickly locate the target items. Attached Figure Description

Detailed Implementation

[0039] The present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0040] In the description of this application: unless otherwise stated, "a plurality of" means two or more. The terms "first," "second," etc., in this application are intended to distinguish the objects referred to and do not have any special meaning in terms of technical connotation (e.g., they should not be construed as an emphasis on importance or order). Expressions such as "comprising," "including," and "having" also mean "not limited to" (certain units, components, materials, steps, etc.).

[0041] The terms used in this application, such as "upper," "lower," "left," "right," and "middle," are generally used to facilitate intuitive understanding by referring to the accompanying drawings, and are not absolute limitations on the positional relationships in the actual product. Changes in these relative positional relationships, without departing from the technical concept disclosed in this application, should also be considered within the scope of this application.

[0042] This application provides a height-adjustable and rotatable storage rack that addresses the problem of existing storage devices being unfriendly to the elderly and those with lumbar spine disorders. Firstly, the height-adjustable and rotatable storage rack allows users to access items at different heights without having to tiptoe, bend over, or squat, avoiding excessive strain on the lower back and the risk of falls. Secondly, the height-adjustable and rotatable storage rack makes all items inside easily visible to the user, eliminating the risk of imbalance caused by reaching out to retrieve items. Thirdly, the height-adjustable and rotatable storage rack simplifies the operation process, enabling those with weaker physical strength to independently adjust and use the storage rack, improving the safety and convenience of daily storage. Furthermore, the height-adjustable and rotatable storage rack features a drawer design with open shelves, and each shelf has an open area with lighting to facilitate users finding and retrieving items from the next drawer.

[0043] The height-adjustable and rotatable storage rack provided in this application employs a spiral lifting transmission system as its core drive device. This spiral lifting transmission system mainly consists of a drive motor, a threaded rod, and a nut. When the drive motor starts, it drives the threaded rod to rotate, and the nut moves vertically up and down along the axis of the threaded rod, achieving smooth lifting and lowering of the storage rack. This spiral lifting structure features high transmission precision and strong load-bearing capacity, and can accurately control the lifting height to meet the storage height needs of different users, avoiding the cumbersome and physically demanding process of traditional manual adjustment.

[0044] Regarding the rotation function, a bearing is installed between the storage shelf and the outer circumference of the nut. The inner ring of the bearing is fixed to the nut, and the outer ring can drive the storage shelf to rotate under the action of thrust. Therefore, in conjunction with the spiral lifting structure, users can rotate items from any position inside the cabinet to their face without leaning out or moving, solving the problem of inconvenience in accessing items deep inside traditional storage devices. In addition, the operation control of the height-adjustable and rotating storage shelf provided in this application is mainly achieved by foot, which is more labor-saving during use and will not affect the lumbar spine.

[0045] The specific structure of the height-adjustable and rotatable storage rack provided in this application will be described in detail below.

[0046] See Figure 1 , 2 This application provides a height-adjustable and rotatable storage rack, including a base 1. The base 1 has an inner cavity in which a drive motor 4 is disposed. The output shaft of the drive motor 4 passes vertically upward through the base 1 and is adapted and fastened to the bottom end of a threaded rod 5 vertically disposed on the base 1. One or more storage shelves 10 are disposed on the threaded rod 5. Each storage shelf 10 includes a shelf 11 and multiple drawers 14 mounted on the shelf 11. A mounting hole is opened in the middle of the shelf 11, and a bearing 9 is installed in the mounting hole. The inner ring of the bearing 9 is fixedly connected to the outer circumferential surface of a nut 6 adapted and mounted on the threaded rod 5. A guide hole 7 is opened on the side wall of the nut 6 along its axial direction. The nut 6 is slidably connected to a limiting rod 8 through the guide hole 7. The limiting rod 8 is arranged parallel to the threaded rod 5. A lifting button for controlling the forward or reverse rotation of the drive motor 4 is provided on the outer surface of the base 1.

[0047] The above technical solution achieves an integrated design of "electric lifting + free rotation + no need to move items", and brings the following significant benefits to address the pain points of use for the elderly, children and patients with lumbar spine diseases:

[0048] (1) The drive motor 4 drives the threaded rod 5 to rotate, which in turn drives the nut 6 to move up and down along the limit rod 8, realizing the one-button lifting of the storage shelf 10 set on the nut 6, replacing the traditional "disassembly and reassembly". Users only need to operate the lifting button to adjust the height of the storage shelf 10 without tiptoeing or bending over, realizing one-button electric lifting, eliminating the need for disassembly and transportation.

[0049] (2) The shelf 11 is connected to the outer ring of the nut 6 via the bearing 9, and can be rotated 360° with a light push; items deep inside can be taken out by turning them to the front, avoiding the body from leaning forward and losing balance and twisting the waist. The rotation resistance is small, and it can be operated with one hand, which is friendly to patients with arthritis and lumbar spine, and eliminates the risk of leaning out to reach.

[0050] (3) The guide hole 7 on the side wall of nut 6 forms a sliding connection with the limit rod 8 to ensure that nut 6 only moves in a straight line and does not rotate; the bearing further isolates the "lifting" and "rotation" movements, so that the shelf 11 will not drive the threaded rod 5 or the motor shaft when it rotates, and the whole machine is free from jerking and abnormal noise, and runs smoothly and safely.

[0051] (4) The electric travel covers the entire range from the ground to the standing reach of an adult; the same set of mechanisms can be arranged with multiple storage shelves 10, providing a large storage space and taking into account both children's low-level access to items and adults' high-level storage.

[0052] In one embodiment of this application, the threaded rod 5 has an external thread, and the nut 6 has an internal thread that is compatible with it. The lead angle of the threaded pair is less than or equal to the equivalent friction angle. Therefore, the screw-nut 6 mechanism composed of the threaded rod 5 and the nut 6 has self-locking properties and stops when the power is cut off, which can prevent accidental slippage.

[0053] Compared to the fixed height design of traditional fixed lockers and the manual disassembly and adjustment method of ordinary adjustable height lockers, this system achieves automatic lifting and lowering through motor drive, with high adjustment accuracy, strong load-bearing capacity, and precise control of lifting height.

[0054] In one embodiment of this application, the base 1 is disc-shaped, and a beveled surface is provided on one side of the upper surface of the base 1, so that the lifting buttons can be installed on the beveled surface on the left and right sides, making it convenient for the user to step on the buttons.

[0055] In one embodiment of this application, see [link to embodiment]. Figure 2 , 7A top plate 2 is set above the base 1 and is parallel to it. The top plate 2 is connected to the base 1 through a support frame 3. The top end of the threaded rod 5 is rotatably connected to the top plate 2. For example, a bearing is set on the top plate 2, and the threaded rod 5 is rotatably connected to the top plate 2 through the bearing. The bottom of the limiting rod 8 is fixedly connected to the base 1, and the top end of the limiting rod 8 is fixedly connected to the top plate 2. The limiting rod 8 and the threaded rod 5 are parallel. When the threaded rod 5 is driven to rotate, the nut 6 does not rotate with it under the action of the limiting rod 8 and moves up and down along the limiting rod 8.

[0056] In one embodiment of this application, the top plate 2 has a light source on its surface facing the base 1, a circuit assembly connected to the light source is disposed in the inner cavity of the base 1, and a switch button 20 for controlling the light source to turn on and off is disposed on the outer surface of the base 1. See also Figure 1 The switch button 20 can be located on the same side as the lifting button and on the side wall of the disc-shaped base 1, making it convenient for the user to kick.

[0057] Installing a light source on the top plate 2 helps users see items clearly at night or in low-light conditions, preventing accidental picking, dropping, or collisions. This light source can use a large-area soft light panel, providing soft light and wide coverage, which can provide basic lighting for the entire storage area.

[0058] In addition, the top plate 2 and the base 1 are rigidly connected to form a frame through the support frame 3. The top of the threaded rod 5 is rotatably connected to the top plate 2, which not only acts as a fulcrum on the screw to improve rigidity, but also has a built-in cable routing channel, which can hide all cables inside the support frame 3 and the top plate 2, resulting in a neat appearance and avoiding the tripping risk caused by cables dragging on the ground.

[0059] Furthermore, the light source switch button 20 is located on the outer surface of the base 1, close to the ground. Users do not need to bend over or touch it with their hands; they can easily control the light by simply kicking it with their toes. This kick-type design provides a convenient operating experience, which is both labor-saving and practical, making lighting control more flexible and efficient, and making life more convenient for the elderly and patients with lumbar spine diseases.

[0060] In one embodiment of this application, see [link to embodiment]. Figures 8 to 10 The shelf 11 includes a central connecting block 12 and a plurality of mounting plates 13 radially distributed along the outer periphery of the central connecting block 12. A mounting hole for mounting a bearing 9 is formed at the center of the central connecting block 12. Between any two adjacent mounting plates 13, a mounting position for a drawer 14 is formed, a storage area for a shelf 16 is formed, a hanging area for a hook 15 is formed, or an empty area 17 is formed for easy observation of the lower storage shelf 10. Each storage shelf 10 has two empty areas 17, which are arranged opposite each other. A light strip 18 is provided between the two mounting plates 13 forming the empty area 17.

[0061] The middle connecting block 12 of the aforementioned shelf 11 can be a cube or a cylinder. Several mounting plates 13 are radially distributed along its outer periphery to maximize the use of its horizontal space and improve space utilization.

[0062] The adjacent mounting plates 13 on the aforementioned shelf 11 can be configured as drawers 14, shelves 16, hooks 15, or empty areas as needed, realizing four storage modes: drawers for small items, shelves for larger items, hooks for hanging bags / umbrellas / keys, etc., and empty areas for viewing the lower layers, thus meeting the user's needs.

[0063] In addition, the two opposing 180° empty zones form an "observation window," allowing users to see the items below directly through the empty zone when rotating, avoiding repeated lifting and lowering to search; the built-in light strip 18 in the empty zone can be raised and lowered synchronously with the shelf 11, providing unobstructed downward lighting to solve the problem of deep shadows, making it safer to retrieve items at night.

[0064] In one embodiment of this application, see [link to embodiment]. Figure 7 Multiple storage shelves 10 are spaced apart on the threaded rod 5. The radial dimensions of the multiple storage shelves 10 gradually decrease from bottom to top, and the empty areas 17 on any two adjacent storage shelves 10 are staggered. This three-dimensional staggered view design allows users to always see directly down through the empty area on the upper layer during rotation, completely eliminating the "upper layer blocking the lower layer" problem caused by the stacking of traditional shelves 16. Elderly people do not need to repeatedly lift and lower to find items. In addition, the staggered arrangement of the light strips 18 on each layer prevents them from blocking each other, allowing light to flow down along the conical space to form soft, gradual lighting. When retrieving items at night, it not only illuminates the current layer but also provides auxiliary light for the lower layer, reducing the need for elderly users to frequently turn on the main light, thus combining energy saving and eye protection. Furthermore, the gradual decrease in radial dimensions of the multiple storage shelves 10 from bottom to top lowers the center of gravity, significantly reducing the amount of swaying during lifting or rotation, preventing items on the top layer from being thrown out due to inertia, making the whole machine more stable and safer.

[0065] In one embodiment of this application, slide rails 19 are provided on the two mounting plates 13 forming the drawer mounting position, and sliding connectors adapted to the slide rails 19 are provided on both sides of the drawer 14. Handles can also be provided on the drawer 14 to facilitate user pull-out use.

[0066] In one embodiment of this application, see [link to embodiment]. Figure 1The lifting buttons include an up button 21 and a down button 22. Operating the up button 21 controls the drive motor 4 to start rotating forward, causing the threaded rod 5 to rotate clockwise, which in turn moves the nut 6 upward along the limit rod 8, thus raising the storage shelf 10. Operating the down button 22 controls the drive motor 4 to start rotating in reverse, causing the threaded rod 5 to rotate counterclockwise, which in turn moves the nut 6 downward along the limit rod 8, thus lowering the storage shelf 10. Simultaneously, the inner ring of the bearing 9 is connected to the outer circumference of the nut 6 via a key, and the outer ring of the bearing 9 is fixedly connected to the mounting holes on the shelf 11 via flanges and bolts. The shelf 11 can rotate around the center of the threaded rod 5 under external force.

[0067] Therefore, the various components of the height-adjustable and rotating storage rack provided in this application work together to provide users with convenient and safe storage functions. The base 1 serves as a support structure and integrates a drive motor 4. The motor can be controlled to rotate forward or backward via a lifting button, driving the threaded rod 5 to rotate clockwise or counterclockwise, thereby causing the storage shelf 10 to move vertically. This allows users to easily access items at high or low locations, avoiding safety hazards caused by tiptoeing, bending over, or twisting their bodies. The storage shelf 10 includes a shelf 11 and drawers 14, hooks 15, shelves 16, etc., installed on it. The bearing 9 at the center of the shelf 11 is connected to the nut 6, allowing the storage shelf 10 to rotate around the threaded rod 5, quickly positioning and adjusting the storage direction. The top plate 2 provides additional stability and is equipped with a light source, allowing users to operate better in the dark. The limit rod 8 ensures that the nut 6 can only move up and down vertically, preventing lateral displacement. This application ensures that the drawer 14 can be smoothly pulled out or pushed in by setting up a slide rail 19 and a handle.

[0068] The following describes the usage process and structural principle of the height-adjustable and rotating storage rack provided in this application.

[0069] First, the user presses the up button 21 or down button 22 to make the drive motor 4 rotate forward or reverse, thereby raising or lowering the drawer 14 to a comfortable access height (for example, for an elderly person who is 1.6m tall, the access height is 1.1-1.3 meters). When the drive motor 4 starts to rotate, the torque of its output shaft is transmitted to the threaded rod 5, causing the threaded rod 5 to rotate synchronously along its own axis. The nut 6, which is compatible with the external thread of the threaded rod 5, originally tends to rotate along the axis of the threaded rod 5 under the helical driving force generated by the rotation of the threaded rod 5. However, due to the constraint of the limiting rod 8 (the limiting rod 8 is connected to the nut 6 through the guide hole 7), the rotational freedom of the nut 6 is effectively restricted, so that the nut 6 can only move stably up and down along the axis of the threaded rod 5.

[0070] Secondly, when the target storage shelf smoothly rises to the desired height under the action of the drive mechanism, the shelf forms a comfortable angle with the operator's line of sight or reach, and the position of each drawer is clearly visible. If an item needs to be retrieved from a particular drawer, there's no need to adjust the overall height of the device or move the operator's body. Simply apply a suitable rotational force to the shelf, and it will rotate flexibly around its central axis. As the rotation progresses, the target drawer, which was originally located on the side or back and inconvenient to reach directly, will gradually be brought to the operator's front. This rotation not only simplifies the retrieval process but also allows the operator to easily align the drawer handle while maintaining a comfortable standing posture, quickly opening the drawer and retrieving items, effectively improving the convenience and efficiency of item retrieval. When an external force is applied to the storage shelf to make it rotate, the bearing, with the rolling characteristics of its own rolling elements, effectively buffers and directionally transmits the force generated by the rotation. This greatly reduces the torque interference on the nut, thus ensuring that the nut can maintain a relatively stable state during the rotation of the shelf. It will not cause unnecessary displacement, shaking or deformation due to the rotation of the shelf, ensuring that all components in the entire mechanical structure operate in an orderly manner according to their preset functions, and ensuring that the rotation operation will not interfere with the movement state of the nut.

[0071] When using traditional lockers, if a user wants to retrieve an item but can't remember which drawer it's in, they have to search through each shelf. The drawers in this application feature a lidless design, which helps users clearly see (and retrieve) the items inside. Each shelf also has two empty areas (i.e., empty areas 17, equipped with lights), making it easy for users to observe the items inside. For example, if a user wants to retrieve something from the third shelf (the bottom shelf), they can rotate the empty area of ​​the second shelf (the shelf above the bottom shelf) to their viewing angle, allowing them to see the items on the third shelf through that empty area.

[0072] In summary, the height-adjustable and rotating storage rack provided in this application achieves lifting and rotation functions through integrated components such as a motor, threaded rod, storage shelves, top plate, light source, and limit rod, providing a convenient, safe, and comfortable user experience for the elderly, patients with lumbar spine diseases, and people with disabilities.
