Description

Technical Field

[0001] This application relates to the technical field of cabinets, and in particular to an intelligent lift-up cabinet. Background Technology

[0002] Traditional kitchen wall cabinets are designed primarily to provide additional storage space. The space underneath is typically used to store commonly used kitchen items such as stoves, pots and pans, tableware, and condiments. This layout facilitates the access of items during the cooking process and improves the efficiency of kitchen work.

[0003] With the advancement of technology and the diversification of user needs, lift cabinets have gradually gained attention as an innovative storage solution. Lift cabinets are controlled by mechanical or electric systems to move the cabinets up and down, aiming to provide a more flexible user experience and optimize space utilization. However, this design has encountered a significant limitation in actual use: when the lift cabinet is lowered to the same height as the countertop, there must be no obstructions under the cabinet in order to ensure its normal operation and avoid collisions.

[0004] In a conventional kitchen, the space under the cabinets is designed for convenient storage and use, and is used to place various cooking utensils and seasonings. If a lift-up cabinet is used, the user has to replan this space. The area under the cabinets needs to be emptied before each lifting operation, which significantly increases the inconvenience and labor intensity. Therefore, a lift-up cabinet is needed that can meet the lifting requirements of the cabinets without affecting the space underneath. Summary of the Invention

[0005] To address the issue of clearance below the cabinet during the lifting and lowering process, an intelligent lifting cabinet solution has been developed.

[0006] The above-mentioned objective of this application is achieved through the following technical solution:

[0007] A smart lift cabinet includes a cabinet and a lift cabinet. Vertical first slide rails are fixed to the two inner side walls of the cabinet. The lift cabinet includes a first cabinet body, a second cabinet body, and a fixing plate. Second slide rails that slide within the first slide rails are provided on the two outer side walls of the first cabinet body. A winch is provided at the top of the cabinet to drive the second slide rails to slide up and down along the first slide rails. The second cabinet body is horizontally slidably connected below the first cabinet body. The fixing plate is fixed to the bottom of the rear end of the first cabinet body. A pushing mechanism is provided on the side of the fixing plate facing the second cabinet body to push the second cabinet body horizontally. An infrared sensor is provided on the inner side wall of the cabinet body to detect the first cabinet body, and the electrical signal output by the infrared sensor is used to drive the pushing mechanism to push the second cabinet body.

[0008] By adopting the above technical solution, both the first and second cabinets slide vertically up and down using a winch. When the first cabinet descends to a certain height and the infrared sensor no longer detects it, the infrared sensor releases a signal to the pushing mechanism, which then moves the second cabinet out of the cabinet. When the first cabinet rises to a certain height and the infrared sensor can detect it again, the pushing mechanism pulls the second cabinet below the first cabinet, allowing it to retract back into the cabinet. During the descent of the first cabinet, the second cabinet slides and translates, creating a clearance space below the first cabinet. This prevents the second cabinet from colliding with items placed below, thus satisfying both the lifting and lowering requirements of the cabinet and allowing items to be placed below it. Furthermore, each time the cabinet is raised or lowered, it is not necessary to empty the items below, improving the space utilization rate under the cabinet.

[0009] Optionally, the distance between the infrared sensor and the bottom of the cabinet is less than the vertical height of the first cabinet.

[0010] By adopting the above technical solution, it can be ensured that the second cabinet can only slide horizontally when the bottom of the first cabinet moves down to the outside of the cabinet bottom. When the first cabinet is still inside the cabinet, the risk of the second cabinet sliding and colliding with the inner side wall of the cabinet is avoided.

[0011] Optionally, the pushing mechanism includes cylinders, and the number of cylinders is set to at least two, which are located at both ends of the fixed plate respectively.

[0012] By adopting the above technical solution, the symmetrical layout of multiple cylinders provides balanced thrust, ensuring the smooth sliding of the second cabinet and avoiding tilting or jamming caused by pushing from one side. At the same time, the cylinders have a fast response speed and can achieve rapid start and stop in conjunction with infrared sensors, thus improving the level of intelligence.

[0013] Optionally, at least two sets of support mechanisms are provided on the two inner side walls of the cabinet. A fixing block connecting the two outer side walls of the lifting cabinet and the two second slide rails is fixed between them. The support mechanism includes a support member fixed on the inner side wall of the cabinet. The support member is located on one side of the fixing block. An electromagnet and an iron part driven by the electromagnet are installed in the support member. A return spring is fixed between one side of the iron part and the electromagnet. A support block is provided on the other side of the iron part and is movably embedded in the iron part. When the second slide rail moves the fixing block down, the upper surface of the support block abuts against the fixing block. When the second slide rail moves the fixing block up, the fixing block presses the support block against the iron part.

[0014] By adopting the above technical solution, when the lifting cabinet moves downward, the electromagnet is energized, and the electromagnet generates magnetic force to attract the iron parts, preventing the iron parts from affecting the downward movement of the lifting cabinet. When the lifting cabinet moves upward, the electromagnet is disconnected from the power supply, and the electromagnet no longer generates magnetic force. The iron parts are pushed by the elastic potential energy of the return spring. As the second slide rail drives the fixed block to slide upward, the fixed block will press against the support block inside the iron parts. If the transmission rope is disconnected from the second slide rail, the support block located below the fixed block can provide support for the fixed block, avoiding the risk of the lifting cabinet falling straight down and improving the safety performance of the cabinet.

[0015] Optionally, the support mechanism further includes a connector, the two ends of which are fixedly connected to the support and the inner sidewall of the cabinet, respectively, and the end of the connector facing the support is aligned with the fixed block in a sliding direction perpendicular to the second slide rail.

[0016] By adopting the above technical solution, the connector enhances the connection strength between the support and the cabinet side wall, ensuring that the support mechanism does not deform when bearing the weight of the lifting cabinet. At the same time, when the electromagnet no longer generates a magnetic force to attract the iron parts, the risk of the support blocks on the iron parts colliding with the second slide rail is reduced, ensuring that the support blocks on the iron parts are all located on one side of the fixed block.

[0017] Optionally, the number of the support mechanisms in the same group is set to two, and they are located on both sides of the fixing block respectively.

[0018] By adopting the above technical solution, the support mechanisms are located on both sides of the fixed block, which can provide bidirectional support to the fixed block, ensuring that the fixed block is subjected to uniform force during up and down movement, avoiding tilting or displacement caused by unilateral support, thereby improving the overall stability of the lifting cabinet.

[0019] Optionally, the number of support blocks is set to multiple, and they are evenly spaced on the iron part.

[0020] By adopting the above technical solution, the installation of multiple support blocks can more quickly support the fixed block after the transmission rope and the second slide rail are accidentally disconnected, which can shorten the distance the fixed block falls and moves downward. Thus, even if the lifting cabinet falls accidentally, the reduced downward distance can ensure the stability of the lifting cabinet.

[0021] Optionally, the iron part is provided with a rotating shaft, and the support block includes a movable end rotatably connected to the rotating shaft and a support end extending outside the iron part, and the iron part has a limiting groove for the support end to be movably embedded.

[0022] By adopting the above technical solution, when the second slide rail moves the fixed block upward, the fixed block can press against the support end and embed it in the limiting groove, avoiding interference between the support end and the fixed block, thereby ensuring a smoother upward movement of the fixed block and reducing the risk of mechanical friction. At the same time, the support end can also provide support for the bottom of the fixed block, avoiding the risk of the lifting cabinet falling straight down due to accidental disconnection between the transmission rope and the second slide rail, thereby improving the safety performance of the lifting cabinet.

[0023] Optionally, the support block is inclined, and the support end is higher than the movable end that is rotatably connected to the rotating shaft.

[0024] By adopting the above technical solution, when the second slide rail drives the fixed block to move upward, the inclined support block makes it easier for the fixed block to press the support end into the limiting groove, ensuring that the fixed block can pass smoothly through the limiting action of the support block during the upward movement of the second slide rail. At the same time, if the second slide rail and the transmission rope are accidentally disconnected, the inclined support block can provide good support for the fixed block, thus improving the safety of the lifting cabinet.

[0025] In summary, this application has at least the following beneficial effects:

[0026] 1. The lift cabinet features intelligent lifting functionality. The second cabinet automatically makes room when the first cabinet descends, preventing collisions with items below and improving the utilization of space under the cabinet.

[0027] 2. If the connection between the second slide rail and the transmission rope is accidentally broken, the support block can provide additional support to the fixed block, preventing the lifting cabinet from falling vertically and improving the safety of the lifting cabinet in case of an accident.

[0035] The following section provides a more detailed description, in conjunction with the accompanying diagrams:

[0036] As attached Figure 1 As shown, an intelligent lifting cabinet includes a cabinet 1 and a lifting cabinet 2 located inside the cabinet 1. The cabinet 1 is fixedly installed on the wall. A lifting device 3 is installed inside the cabinet 1 to move the lifting cabinet 2 up and down inside the cabinet 1. The front and bottom ends of the cabinet 1 are hollowed out to realize the up and down movement of the lifting cabinet 2 and the storage and retrieval of items.

[0037] As attached Figure 2 As shown, the lifting device 3 includes a first slide rail 31, a second slide rail 32, a rotating wheel 33, and a winch 34. There are two first slide rails 31, which are vertically fixed on the two inner side walls of the cabinet 1. There are also two second slide rails 32, which are vertically fixed on the two outer side walls of the lifting cabinet 2. The two second slide rails 32 are slidably connected to the two first slide rails 31. The configuration of the first slide rails 31 provides guidance and protection for the sliding of the second slide rails 32, thereby enabling the lifting cabinet 2 to move up and down inside the cabinet 1.

[0038] There are two rotating wheels 33, which are located above the two second slide rails 32 respectively. Both rotating wheels 33 are fixedly connected to the top of the cabinet 1. The winch 34 is fixed to the top of the cabinet 1. The winch 34 has a transmission rope 341 on both sides. The end of the transmission rope 341 passes through the rotating wheel 33 and is fixedly connected to the top of the second slide rail 32. When the winch 34 is started, the transmission rope 341 drives the second slide rail 32 to move up and down in the first slide rail 31, realizing the lifting cabinet 2 in the cabinet 1.

[0039] As attached Figure 2 and attached Figure 3As shown, the lifting cabinet 2 includes a first cabinet body 21, a second cabinet body 22, and a fixing plate 23. The first cabinet body 21 is the main load-bearing structure of the lifting cabinet 2. Two fixing blocks 211 are fixed on the two outer side walls of the first cabinet body 21 respectively. The other ends of the two fixing blocks 211 are fixedly connected to two second slide rails 32 respectively. Thus, the first cabinet body 21 slides up and down on the first slide rail 31 through the second slide rails 32, so that the first cabinet body 21 can move up and down in the cabinet 1. A first shelf 212 is fixed on the two inner side walls at the bottom of the first cabinet body 21 for storing items. Two relatively parallel third slide rails 213 are fixed on the two inner side walls at the bottom of the first cabinet body 21 respectively. The third slide rails 213 are located below the first shelf 212.

[0040] The second cabinet 22 is located below the first shelf 212. Two relatively parallel fourth slide rails 221 are fixed on the two outer side walls of the top of the second cabinet 22. The fourth slide rails 221 are horizontally connected to the third slide rail 213, so that the second cabinet 22 can move horizontally below the first cabinet 21. The sliding direction of the second cabinet 22 is perpendicular to the sliding direction of the first cabinet 21. Thus, when the first cabinet 21 descends to a certain height, the second cabinet 22 can slide outward of the cabinet 1 to create a clearance space and avoid collision with the items below.

[0041] One end of the fixing plate 23 is fixed to the bottom of the rear end of the first cabinet 21, and the other end extends vertically downward. A pushing mechanism 4 is provided on the side of the fixing plate 23 facing the second cabinet 22. When the first cabinet 21 is lowered to a certain height, the pushing mechanism 4 is used to slide the second cabinet 22 to the outside of the cabinet 1.

[0042] The pushing mechanism 4 includes a cylinder 41 and an infrared sensor 42. The number of cylinders 41 is set to at least two. One end of the cylinder 41 is fixed to the side of the fixing plate 23 facing the second cabinet 22. The piston rod of the cylinder 41 is fixedly connected to the side of the second cabinet 22 facing the fixing plate 23. The two cylinders 41 are located at both ends of the fixing plate 23 respectively. When the cylinder 41 pushes the second cabinet 22, it can provide a balanced thrust to ensure the stability and reliability of the second cabinet 22 during the sliding process.

[0043] Infrared sensor 42 is located at the rear end of lifting cabinet 2. Infrared sensor 42 is electrically connected to cylinder 41 and is fixed to the inner wall of cabinet 1. Infrared sensor 42 can detect the vertical movement of lifting cabinet 2. When the first cabinet 21 descends to a certain height, the detection end of infrared sensor 42 no longer detects the first cabinet 21. Then, infrared sensor 42 releases an electrical signal to cylinder 41, controlling the piston rod of the air pipe to extend, pushing the second cabinet 22 along the fourth slide rail 221 towards the outside of cabinet 1, thus creating a clearance space at the bottom of the first cabinet 21. After the first cabinet 21 begins to rise, infrared sensor 42 detects the presence of the first cabinet 21 again. Infrared sensor 42 releases an electrical signal to cylinder 41, controlling the piston rod of cylinder 41 to retract, pulling the second cabinet 22 back along the fourth slide rail 221 to below the first cabinet 21.

[0044] The distance between the infrared sensor 42 and the bottom of the cabinet 1 is less than the vertical height of the first cabinet 21. This ensures that the second cabinet 22 can only slide horizontally when the bottom of the first cabinet 21 moves down to the outside of the bottom of the cabinet 1. When the first cabinet 21 is still inside the cabinet 1, the risk of the second cabinet 22 sliding and colliding with the inner wall of the cabinet 1 is avoided.

[0045] As attached Figure 2 and attached Figure 4 As shown, two sets of support mechanisms 5 are fixed on the two inner side walls of the cabinet 1. There are two support mechanisms 5 in the same set, and they are located on both sides of the fixed block 211. When the second slide rail 32 drives the fixed block 211 to move up and down, the support mechanism 5 is used to provide limit and support for the fixed block 211. In this way, when the second slide rail 32 and the transmission rope 341 are accidentally disconnected, the support mechanism 5 can provide bidirectional support for the fixed block 211, ensuring that the fixed block 211 is evenly stressed during the up and down movement, avoiding tilting or displacement caused by unilateral support, thereby improving the overall stability of the lifting cabinet 2.

[0046] As attached Figure 4 and attached Figure 5 As shown, the support mechanism 5 also includes a connector 51, a support 52, and a support block 56. There are two connectors 51 in the same support mechanism 5. The two connectors 51 are located on both sides of the first slide rail 31. One end of the connector 51 is fixedly connected to the inner side wall of the cabinet 1, and the other end of the connector 51 is aligned with the fixed block 211 at a position perpendicular to the sliding direction of the second slide rail 32.

[0047] The support member 52 is fixedly connected to the end of the connector 51 away from the inner wall of the cabinet 1. There are two support members 52 in the same support mechanism 5. The two support members 52 are located on both sides of the fixing block 211. The support member 52 is hollowed out on the side facing the fixing block 211. An electromagnet 53 electrically connected to the power supply is fixed inside the support member 52. An iron part 54 parallel to the electromagnet 53 is also provided inside the support member 52. The iron part 54 is located on the side of the support member 52 facing the fixing block 211. A return spring 55 is installed between the iron part 54 and the electromagnet 53 to fix the iron part 54. When the electromagnet 53 is energized and generates magnetic force, the electromagnet 53 can attract the iron part 54 away from the fixing block 211. When the electromagnet 53 is de-energized, the electromagnet 53 no longer generates magnetic force to attract the iron part 54. The iron part 54 will be pushed back to the initial position under the elastic potential energy of the return spring 55.

[0048] As attached Figure 5 and attached Figure 6 As shown, the support block 56 is movably embedded in the side of the iron piece 54 facing the fixed block 211. There are multiple support blocks 56, which are evenly spaced on the iron piece 54. Multiple rotating shafts 542 are provided inside the iron piece 54. The number of rotating shafts 542 is equal to the number of support blocks 56. The support block 56 includes a movable end 561 and a support end 562. The movable end 561 is located inside the iron piece 54 and is rotatably connected to the rotating shaft 542. The support end 562 extends outside the iron piece 54.

[0049] The support block 56 is inclined on the iron plate, with the support end 562 higher than the movable end 561 rotatably connected to the rotating shaft 542. The iron plate 54 also has a limiting groove 541 on the side facing the fixed block 211 for the support end 562 to be inserted into. When the second slide rail 32 drives the fixed block 211 to move upward, the inclined setting of the support block 56 can guide the fixed block 211. At the same time, the two sides of the fixed block 211 will press against the two support blocks 56 and be inserted into the limiting groove 541 to move upward. After the fixed block 211 passes the two relatively parallel support blocks 56, if the second slide rail 32 accidentally slips, the support end 562 on the two support blocks 56 can provide support for the fixed block 211, which improves the safety performance of the cabinet 1.

[0050] Working principle

[0051] The winch 34 drives the second slide rail 32 to move up and down within the first slide rail 31 via the transmission rope 341, thereby raising and lowering the first cabinet 21. When the first cabinet 21 descends to a certain height, the infrared sensor 42 no longer detects the presence of the first cabinet 21. The infrared sensor 42 sends a signal to the cylinder 41, which then drives the second cabinet 22 to slide outwards from the cabinet 1, creating a clearance space below the first cabinet 21. When the first cabinet 21 rises to a certain height, the infrared sensor 42 detects the presence of the first cabinet 21 again. The infrared sensor 42 sends a signal to the cylinder 41, which then pulls the second cabinet 22 back below the first cabinet 21. Both the first cabinet 21 and the second cabinet 22 rise into the cabinet 1.

[0052] During the descent of the lifting cabinet 2, the electromagnet 53 is energized to generate a magnetic force that attracts the iron parts 54, allowing the fixing block 211 to move up and down between the two iron parts 54. The support block 56 on the iron parts 54 will not obstruct the fixing block 211. During the ascent of the lifting cabinet 2, the electromagnet 53 is de-energized, and the iron parts 54 are reset towards the fixing block 211 under the elastic potential energy of the return spring 55. The fixing block 211 will press against the limit block and embed itself in the limit groove 541 to rise. If the connection between the second slide rail 32 and the transmission rope 341 is accidentally broken, the support block 56 below the fixing block 211 will provide additional support for the fixing block 211, thereby preventing the lifting cabinet 2 from falling and ensuring the safety of the lifting cabinet 2.
