[0049] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0050] like Figures 1 to 6As shown, this embodiment provides a cabinet with a roller shutter door structure, including a solid, a guide structure 2, a roller shutter door body 3, a retracting structure 4, and an unwinding structure 5. The cabinet body 1 surrounds a storage chamber and has a storage opening connected to the storage chamber. The guide structure 2 extends vertically and is located at the storage opening. The roller shutter door body 3 is arranged around the outside of the cabinet body 1 and is slidably mounted on the guide structure 2 to selectively close the storage opening. The retracting structure 4 is located on the cabinet body 1, and one end of the roller shutter door body 3 is connected to the retracting structure 4, which is used to retract the roller shutter door body 3. The unwinding structure 5 is located on the top side of the cabinet body 1, and the roller shutter door body 3 is tractably abutted against and engaged with the unwinding structure 5, which is used to drive the roller shutter door body 3 to unwind. When it is necessary to retrieve or store clothing, the roller shutter body 3 can slide along the guide structure 2 under the drive of the retraction structure 4, and the roller shutter body 3 can be completely separated from the storage opening, realizing the complete opening of the storage chamber (i.e., Figure 2 As shown in the diagram, this makes it easier to store and organize clothes; when the cabinet needs to be closed, under the drive of the unwinding structure 5, the end of the roller shutter body 3 away from the rewinding structure 4 can slide downwards in the vertical direction until the storage opening is completely blocked (i.e., Figure 1 (As shown in the diagram). Meanwhile, the opening or closing of the roller shutter body 3 does not require external space, saving space and optimizing the spatial layout.

[0051] Specifically, in this embodiment, the winding structure 4 is located on the back side of the cabinet 1; in other embodiments, the winding structure 4 can also be located on the top side of the cabinet 1. It should be noted that when the winding structure 4 is located on the top side of the cabinet 1, the winding structure 4 is located behind the unwinding structure 5, that is, the winding structure 4 is closer to the back side of the cabinet 1 than the unwinding structure 5, so as to ensure that the storage opening can be selectively closed or opened.

[0052] Optionally, refer to Figure 3 The guide structure 2 has a guide groove 21, and the end of the roller shutter door body 3 is slidably disposed in the guide groove 21, which provides a guiding function for the sliding of the roller shutter door body 3, and also provides a certain limiting function.

[0053] Specifically, in this embodiment, the guide structure 2 is not only provided on the front side of the cabinet 1, but also on the top and back sides of the cabinet 1. Furthermore, the front guide structure 2 and the top guide structure 2 are connected in an arc shape, and the back guide structure 2 and the top guide structure 2 are also connected in an arc shape to ensure the smooth movement of the roller shutter door body 3. Moreover, the guide structure 2 is installed on the cabinet 1 using common fasteners such as bolts or screws, making installation convenient and easy.

[0054] Furthermore, the roller shutter body 3 is provided with a rolling element that can roll along the guide structure 2. The rolling element converts the sliding friction between the roller shutter body 3 and the guide structure 2 into rolling friction, making the opening and closing of the roller shutter body 3 smoother. For example, the rolling element is a roller.

[0055] Optionally, such as Figure 5 As shown, the winding structure 4 includes a winding drive mechanism 41 and a winding shaft 42. The winding drive mechanism 41 is mounted on the cabinet 1. The winding shaft 42 is rotatably mounted on the cabinet 1 around its own axis and connected to the output end of the winding drive mechanism 41. One end of the roller shutter door body 3 is connected to the winding shaft 42. Driven by the winding drive mechanism 41, the winding shaft 42 rotates around its own axis, causing the end of the roller shutter door body 3 away from the winding drive mechanism 41 to gradually separate from the storage opening, and causing part of the roller shutter door body 3 to be wound up on the winding shaft 42, thus opening the storage opening.

[0056] Specifically, in this embodiment, two winding drive mechanisms 41 are provided at intervals. The two ends of the winding shaft 42 are connected to the output ends of the two winding drive mechanisms 41 respectively. The two winding drive mechanisms 41 can rotate synchronously and in the same direction to realize the smooth sliding opening of the roller shutter door body 3. For example, the winding drive mechanism 41 is a motor commonly used in the art.

[0057] Furthermore, the cabinet 1 has a mounting slot 11, within which the winding drive mechanism 41 and the winding shaft 42 are both housed. This arrangement avoids the winding structure 4 from occupying additional external space, achieving the installation of the winding structure 4 without affecting the storage space of the cabinet 1. Specifically, in this embodiment, the mounting slot 11 is located on the back side of the cabinet 1.

[0058] Specifically, two first mounting blocks are spaced apart in the mounting slot 11, and the fixed ends of the two winding drive mechanisms 41 are respectively set on the two first mounting blocks.

[0059] Optionally, continue to refer to Figure 5The unwinding structure 5 includes two unwinding assemblies 51 spaced apart along a first horizontal direction. Each unwinding assembly 51 includes an unwinding drive mechanism 511 and a drive shaft 512. The unwinding drive mechanism 511 is mounted on the cabinet 1. The drive shaft 512 extends along a second horizontal direction and is rotatably mounted on the cabinet 1 around its own axis. The drive shaft 512 is connected to the output end of the unwinding drive mechanism 511 and is drively connected to the roller shutter door body 3. The first horizontal direction is perpendicular to the second horizontal direction. Driven by the unwinding drive mechanism 511, the drive shaft 512 rotates around its own axis to unwind the roller shutter door body 3 and close the storage opening. Specifically, two unrolling components 51 are spaced apart at both ends of the top side of the cabinet 1, so that the roller shutter body 3 located on the front side of the cabinet 1 and the roller shutter body 3 located on the top side of the cabinet 1 form an arc transition, and the roller shutter body 3 located on the top side of the cabinet 1 and the roller shutter body 3 located on the back side of the cabinet 1 form an arc transition, so as to ensure the smoothness of the sliding of the roller shutter body 3.

[0060] Specifically, in this embodiment, each unwinding assembly 51 includes two unwinding drive mechanisms 511. The two ends of the transmission shaft 512 are correspondingly located at the output ends of the two unwinding drive mechanisms 511, and the two unwinding drive mechanisms 511 can rotate synchronously and in the same direction to ensure that the roller shutter door body 3 slides and closes smoothly. For example, the unwinding drive mechanism 511 is a motor commonly used in the art.

[0061] More specifically, each unwinding assembly 51 also includes two second fixing blocks 513, and the fixing ends of the two unwinding drive mechanisms 511 are respectively disposed on the two second fixing blocks 513.

[0062] Furthermore, during the winding process, the drive shaft 512 rotates along with the winding of the roller shutter body 3 to ensure the smooth opening of the cabinet. During the unwinding process, the two drive shafts 512 rotate synchronously under the drive of the corresponding unwinding drive mechanism 511 to drive the roller shutter body 3 to unwind, thereby achieving the smooth closing of the cabinet.

[0063] Specifically, during the winding process, the connection between the drive shaft 512 and the output end of the unwinding drive mechanism 511 is automatically disconnected, and the drive shaft 512 rotates under the transmission action of the roller shutter body 3. During the unwinding process, the connection between the winding shaft 42 and the output end of the winding drive mechanism 41 is also automatically disconnected to ensure the smooth unwinding of the roller shutter body 3.

[0064] For example, the connection and disconnection methods between the drive shaft 512 and the output end of the unwinding drive mechanism 511, and the connection and disconnection methods between the winding shaft 42 and the output end of the winding drive mechanism 41 are all existing technologies and will not be described in detail here.

[0065] Furthermore, one of the roller shutter door body 3 and the drive shaft 512 is provided with a toothed portion, and the other is provided with a toothed portion, with the toothed portion meshing with the toothed portion. The above arrangement avoids the creep phenomenon that may exist in friction transmission through meshing transmission, making the transmission of the roller shutter door body 3 more stable and precise, and reducing the dependence on tension force.

[0066] Optionally, the two drive shafts 512 are respectively supported on the bottom of the roller shutter door body 3. While ensuring the smooth transmission of the roller shutter door body 3, they can also provide a certain load-bearing effect to further ensure the smoothness of the cabinet opening or closing.

[0067] Optionally, a first sensor and a second sensor are spaced apart at the storage opening, and a position sensor is provided on the roller shutter body 3. When the storage opening is fully closed, the position sensor is aligned with the first sensor; when the storage opening is fully open, the position sensor is aligned with the second sensor. This configuration accurately detects whether the roller shutter body 3 is fully open or fully closed, ensuring that the roller shutter body 3 is fully open and fully closed. Simultaneously, when the roller shutter body 3 is opened to its maximum extent, the rewinding drive mechanism 41 is prevented from continuing to operate; when the roller shutter body 3 is fully closed, the unwinding drive mechanism 511 is prevented from continuing to operate, thereby effectively preventing the roller shutter body 3 from being twisted and damaged or the drive mechanism from being overloaded and burned out. Furthermore, during the sliding process of the roller shutter body 3, if it encounters obstacles such as uneven sliding or clothing getting caught, the position sensor can detect the obstruction signal and promptly alert the user.

[0068] For example, the first sensor, the second sensor, and the position sensor are all existing structures, and their specific structures and principles will not be described in detail here.

[0069] Furthermore, the cabinet also includes a control structure 6, which includes a controller and a control panel. The winding structure 4, the unwinding structure 5, the first sensor, the second sensor, and the position sensor are all connected to the controller. The control panel is located on the cabinet body 1 and connected to the controller. Specifically, the control panel has an open button and a close button. Pressing the open button activates the winding drive mechanism 41, causing the roller shutter body 3 to gradually separate from the storage opening. When the position sensor of the roller shutter body 3 is aligned with the second sensor, the winding drive mechanism 41 stops operating, and the storage chamber is fully opened. Pressing the close button activates the unwinding drive mechanism 511, causing the roller shutter body 3 to gradually seal the storage opening. When the position sensor of the roller shutter body 3 is aligned with the first sensor, the unwinding drive mechanism 511 stops operating, and the storage chamber is completely sealed. The operation is simple and convenient, and the opening and closing process of the roller shutter body 3 is smooth. In addition, if the position sensor detects an obstruction signal during the opening or closing of the roller shutter body 3, the position sensor will transmit the obstruction signal to the controller, and the controller will then control the winding drive mechanism 41 or the unwinding drive mechanism 511 to close in time to avoid deformation and damage to the roller shutter body 3.

[0070] More specifically, the control panel also includes speed adjustment buttons, a pause button, and a child lock button, providing corresponding control functions. Pressing the speed adjustment button adjusts the sliding speed of the roller shutter body 3; pressing the pause button stops the roller shutter body 3 at any position; pressing the child lock button locks all buttons on the control panel, preventing them from responding to operations and thus preventing children from accidentally accessing dangerous areas and improving safety.

[0071] For example, the controller and control panel are devices that have been disclosed in the prior art, and their specific structures and principles are the same as those in the prior art, and will not be described in detail here.

[0072] Optionally, a first dustproof plate 7 is spaced apart on the top of the cabinet 1, the first dustproof plate 7 is connected to the cabinet 1, and the roller shutter door body 3 passes through the gap between the cabinet 1 and the first dustproof plate 7; and / or, a second dustproof plate (not shown in the figure) is spaced apart on the back side of the cabinet 1, and the roller shutter door body 3 passes through the gap between the cabinet 1 and the second dustproof plate. The first dustproof plate 7 serves two purposes: firstly, it can shield the roller shutter door body 3 located on the top side of the cabinet 1, preventing dust accumulation; secondly, the first dustproof plate 7 can also be used to support items, improving space utilization. The second dustproof plate, while preventing dust, can also prevent the roller shutter door body 3 located on the back side of the cabinet 1 from interfering with the wall or other furniture, and at the same time, improves the neatness and aesthetics of the cabinet.

[0073] Specifically, the cabinet 1 includes a bottom plate 12, a top plate 15, two front plates 13, two outer side plates 14, and two inner side plates 16. The top plate 15 is vertically spaced above the bottom plate 12. The two front plates 13 are horizontally spaced and connected between the bottom plate 12 and the top plate 15. The two inner side plates 16 are horizontally spaced and connected between the bottom plate 12 and the top plate 15. The bottom plate 12, top plate 15, two front plates 13, and two inner side plates 16 enclose a storage chamber. Guide structures 2 are provided on the sides of the two front plates 13 facing each other. The two outer side plates 14 are horizontally spaced and connected between the bottom plate 12 and the top plate 15 to ensure the overall aesthetics and neatness of the cabinet. A first dustproof plate 7 is vertically spaced above the top plate 15 and connected between the two outer side plates 14.

[0074] Optionally, the cabinet 1 is provided with drawers 8, which are mounted on the base plate 12 and located on the bottom side of the storage chamber. When the storage opening is completely blocked, the drawers 8 are not obstructed by the roller shutter door body 3, and can be directly pulled out for storage and retrieval of items. Specifically, in this embodiment, four drawers 8 are spaced apart along the second horizontal direction; in other embodiments, the drawers 8 may also be spaced apart along the vertical direction, and the number of drawers 8 can be set as needed, without specific limitation here.

[0075] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
