Description

Technical Field

[0001] This utility model relates to the field of cabinet technology, and in particular to an anti-pinch hanging cabinet. Background Technology

[0002] Traditional wall-mounted cabinets are usually fixed in place. For shorter users, it is inconvenient to use them without the help of chairs or other tools when retrieving items from inside the cabinets. To solve this problem, electric wall-mounted lifting cabinets have emerged.

[0003] Existing electric wall-mounted cabinet technology, to a certain extent, meets people's needs for convenient access to items. It achieves the lifting and lowering of the cabinet through a motor drive and the use of steel wire ropes and guide rails. For example, the anti-pinch electric lifting cabinet with patent number CN203986845U uses a connecting rod at the bottom front edge of the cabinet body. A micro switch is installed on the bottom surface of the connecting rod, and a control rod that can slide slightly up and down is located below the connecting rod. When a hand or arm touches the control rod during the upward movement of the shelf, the control rod presses down the micro switch, which transmits a signal to the electrical control box to stop the motor from rotating and reverse its direction, thus achieving the anti-pinch function.

[0004] However, the anti-pinch function in the aforementioned patent only addresses the situation where the hand is between the shelf and the bottom edge of the cabinet during the shelf's ascent; it does not consider the situation where the hand is on either side of the shelf. Furthermore, the control lever is located at the bottom edge of the cabinet, meaning it is not a concealed design, resulting in a less than ideal spatial layout.

[0005] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0028] This utility model provides an anti-pinch hanging cabinet. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0029] Please see Figure 1 , Figure 2 and Figures 4-5This utility model provides an anti-pinch hanging cabinet, including a cabinet body 1 with an open bottom, a cabinet door 2 hinged to the cabinet body 1, a motor 4 and multiple guide wheels 5 set in the top of the cabinet body 1, rails 11 set in both sides inside the cabinet body 1, uprights 12 slidably connected to the corresponding rails 11, and shelves 16 whose ends are fixed to the side walls of the corresponding uprights 12; it also includes a hanging rope 6, with a hanging rope fixing seat 13 set in the side wall of the uprights 12, one end of the hanging rope 6 being fixedly connected to the hanging rope fixing seat 13, and the other end being connected to the motor 4 through the corresponding guide wheels 5; an electrical box 3 is also set in the top of the cabinet body 1, and a control board 7 is set in the electrical box 3. The control board 7 is electrically connected to the motor 4, and the control board 7 is used to monitor the current changes of the motor 4.

[0030] The bottom of the cabinet 1 is open, which allows the shelf 16 to descend and rise. When the motor 4 rotates in the forward direction and releases the hanging rope 6, the column 12 can move downward along the track 11, so that the shelf 16 can descend. Conversely, when the motor 4 rotates in the reverse direction and tightens the hanging rope 6, the column 12 moves upward along the track 11, so that the shelf 16 can rise. During the upward movement, when a person reaches for an item on the shelf 16, their hand may be clamped by the shelf 16 and the cabinet door 2 or cabinet body 1. When the shelf 16 is subjected to a sudden change in external force / gravity, the current of the motor 2 will change instantaneously. This instantaneous change will be captured by the control board 7. That is, the control board 7 is used to collect the instantaneous current change value of the motor 4 and compare the instantaneous current change value with the current value of the motor 4 before the shelf 16 rises. When the instantaneous current value is greater than a certain value / set value, the control board 7 will send a signal to stop the motor 4. The motor 4 will immediately retract a certain distance and stop, so that the shelf 16 can descend a certain distance, ensuring that the person's hand will not be trapped between the shelf 16 and the cabinet body 1 or cabinet door 2, preventing injury, thereby improving the safety and practicality of the wall cabinet.

[0031] Please see Figure 5 In some embodiments, the electrical box 3 is further provided with a wire clamp 8. There are two or more wire clamps 8, which are arranged on both sides of the motor 4 and are used to guide the suspension rope 6. The wire clamps 8 can position the suspension rope 6 and prevent it from deviating too much and falling off the guide wheel 5.

[0032] Please see Figure 3In some embodiments, a limit switch 9 is also provided inside the electrical box 3, and a trigger piece 15 is provided on the upper part of the back of any of the columns 12. The electrical box 3 has a clearance hole for the trigger piece 15 to pass through, and the limit switch 9 is used to sense the trigger piece 15. When the trigger piece 15 on the column 12 rises to the height of the limit switch 9, it indicates that the shelf 16 has risen to the set height. Specifically, after the limit switch 9 senses the trigger piece 15, it sends a signal to the control board 7, and the control board 7 sends a signal to stop the motor 4.

[0033] Please refer to the figure. Figure 6 and Figure 7 In some embodiments, vertically extending grooves are formed on both sides of the track 11, and pulleys 14 are rotatably mounted on the column 12, with the pulleys 14 slidingly disposed in the corresponding grooves. This arrangement prevents the column 12 from directly contacting the track 11 and causing abnormal noise during ascent or descent.

[0034] Please see Figure 1 , Figure 4 and Figure 7 In some embodiments, the bottom of the column 12 is further provided with a hollow base 17, and a floating plate 22 is fixedly connected to the lower surface of the base 17. The floating plate 22 is located below the shelf 16. A spring 18 is provided inside the base 17, with one end of the spring 18 abutting against the inner wall of the base 17 and the other end abutting against the upper surface of the floating plate 22. By setting the floating plate 22 below the shelf 16, the deformation capacity of the spring 18 allows the floating plate 22 to rise a certain distance when it touches an item located below it, avoiding a rigid collision between the item and the shelf 16, which could damage the motor 4. In other words, the floating plate 22 and the spring 18 provide a buffering effect.

[0035] Please see Figure 7 In some embodiments, a positioning post 19 is also provided inside the base 17. The positioning post 19 is vertically arranged, and the spring 18 is sleeved on the positioning post 19. The positioning post 19 and the base 17 are integrally formed structures. During assembly, the spring 18 can be sleeved on the positioning post 19 to achieve quick assembly, and it can also provide guidance for the vertical movement of the spring 18.

[0036] Please see Figure 7In some embodiments, a Hall sensor 20 is also provided inside the base 17, and the Hall sensor 20 and the control board 7 are connected by a spring wire 21. When an object or a hand is below the floating plate 22, i.e., when the floating plate 22 is triggered, the floating plate 22 will generate a corresponding displacement. This displacement is detected by the Hall sensor 20. The Hall sensor 20 generates a corresponding electrical signal based on the detected change in magnetic field or physical quantity. This electrical signal is transmitted to the control board 7. After receiving the signal, the control board 7 performs internal preset logic judgment and processing program, and issues a control command to the motor 4. When the preset stop condition is met, such as receiving a specific signal pattern or signal strength for a certain period of time, the control board 7 will issue a command to stop the motor 4 from rotating, thereby stopping the motor 4 from working and preventing the hanging cabinet from continuing to descend, thus protecting the motor 4.

[0037] Please see Figure 6 and Figure 7 In some embodiments, the column 12 has a hollow structure, and the spring wire 21 is vertically arranged and located inside the column 12. This arrangement makes the spring wire 21 a concealed design. In actual use, when the shelf 16 is lowered, the spring wire 21 is stretched; when the shelf 16 is raised, the spring wire 21 returns to its original state.

[0038] Please see Figure 1 In some embodiments, the number of shelves 16 is multiple, and the multiple shelves 16 are arranged vertically. Through the above arrangement, the wall cabinet has multiple shelves 16, thereby increasing the storage space.

[0039] Please see Figure 2 In some embodiments, the bottom of the electrical box 3 is provided with a mounting hole, in which a light 10 is installed. The light 10 is electrically connected to the control board 7. Specifically, when the shelf 16 is lowered, or when the user presses the "lighting" button, the light 10 can be turned on via signal transmission from the control board 7, so that the user can quickly find the items needed on the shelf 16 in a dimly lit environment.

[0040] In summary, this utility model, by setting up a motor 4, a hanging rope 6, and a column 12, can realize the raising or lowering of the shelf 16; by using the control board 7 inside the electrical box 3 to monitor the instantaneous changes of the motor 4 in real time, the start and stop of the motor 4 can be controlled by the control board 7, ensuring that people's hands will not be caught between the shelf 16 and the cabinet 1 or cabinet door 2, preventing injury, thereby improving the safety and practicality of the wall cabinet; moreover, the motor 4 and the control board 7 are both located inside the electrical box 3, making the space design of the wall cabinet more reasonable and aesthetically pleasing.
