Description

Technical Field

[0001] This utility model relates to an electric lifting cabinet, specifically an electric lifting cabinet that can be manually opened in an emergency. Background Technology

[0002] Electric lift cabinets, with their convenient electric operation, provide users with ample storage space and are widely used in residential and commercial spaces such as kitchens and offices. Electric lift cabinets use a built-in electric lifting mechanism to raise and lower the inner cabinet, facilitating the access to items inside. Existing electric lifting mechanisms link the inner cabinet and the cabinet door together, allowing the door to open and move upwards simultaneously as the inner cabinet descends, thus providing convenience for users to access the items inside.

[0003] However, most lift cabinets on the market rely entirely on electric lifting mechanisms. When a power outage occurs or the electric lifting mechanism malfunctions, users cannot manually open the cabinet, limiting its usability. For example, in a home kitchen, a sudden power outage during cooking prevents users from opening the cabinet to retrieve necessary utensils or ingredients, forcing an interruption of cooking. In an office, a malfunctioning electric lifting mechanism prevents staff from accessing documents within the cabinets, directly impacting work efficiency and production schedules. Sudden power outages or malfunctions causing the mechanism to fail render the lift cabinet unusable in emergencies, reducing its practicality and causing significant inconvenience to users.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. An electric lifting cabinet that can be manually opened in an emergency includes a cabinet body 1 with an open outer end. A fixed door panel 11 and a movable door panel 12 are respectively installed at the upper and lower ends of the cabinet body 11. A lifting assembly 8 and a pushing mechanism are respectively installed on both sides of the back of the movable door panel 12. The lifting assembly 8 and the pushing mechanism are linked together by a connecting seat 5.

[0028] The ejection mechanism includes a sliding seat 2 installed on the back of the movable door panel 12. The sliding seat 2 extends upward and is inclinedly provided with a connecting plate 21. A horizontal sliding mechanism 3 is installed on the connecting plate 21. The movable door panel 12 is pulled outward, and the horizontal sliding mechanism 3 drives the movable door panel 12 to be ejected.

[0029] The inner wall of the cabinet 1 is provided with a vertical sliding mechanism 4. The vertical sliding mechanism 4 and the horizontal sliding mechanism 3 are connected as one unit through the mounting base 6. When the movable door panel 12 is pushed up, the vertical sliding mechanism 4 drives the movable door panel 12 to open upward.

[0030] A guide mechanism 7 is provided between the sliding seat 2 and the inner wall of the cabinet 1. The guide mechanism 7 includes a guide wheel 71 rotatably mounted on the sliding seat 2 and a guide wheel seat 72 connected to the inner wall of the cabinet 1. A guide groove 73 is provided on the guide wheel seat 72, and the guide wheel 71 is built into the guide groove 73 and slides along the guide groove 73.

[0031] The sliding seat 2 is inclined to the side facing the lifting assembly 8 and has an upper moving plate 22. The lifting assembly 8 is pressed on the inclined surface of the upper moving plate 22, generating upward and outward force.

[0032] The lifting assembly 8 includes a transmission chain 81 and a lifting seat 82 fixedly connected thereto. A lifting block 83 is installed on the lifting seat 82. The lifting block 83 has a pressing surface 84 that cooperates with the inclined surface of the lifting plate 22 on the side facing the lifting plate 22. The pressing surface 84 is pressed on the inclined surface of the lifting plate 22.

[0033] The lateral sliding mechanism 3 includes a lateral slide rail 31 and a lateral slider 32 that cooperates with it. The lateral slider 32 slides laterally along the lateral slide rail 31, causing the movable door panel 12 to be pushed out or retracted.

[0034] The vertical sliding mechanism 4 includes a vertical slide rail 41 and a vertical slider 42 that cooperates with it. The vertical slider 42 slides axially along the vertical slide rail 41, causing the movable door panel 12 to rise or fall.

[0035] The mounting base 6 is installed between the vertical slider 42 and the horizontal slide rail 31.

[0036] The guide groove 73 is a horizontally extending groove with open ends.

[0037] Working principle: To address emergencies such as sudden power outages or malfunctions of the electric lifting components, this design incorporates a push-out mechanism that allows manual opening of the lifting cabinet door, ensuring normal operation of the cabinet. This push-out mechanism includes a sliding seat mounted on the back of the movable door panel, which connects to a horizontal sliding mechanism via an upwardly extending and inclined connecting plate.

[0038] When the cabinet door needs to be opened urgently, the user first pulls the movable door panel outward, activating the horizontal sliding mechanism. During the passive pulling of the movable door panel, the horizontal slider of the horizontal sliding mechanism slides laterally along the horizontal rail, pushing the movable door panel away from the outer end face of the fixed door panel.

[0039] It should be noted that a guide mechanism is installed between the sliding base and the inner wall of the cabinet to ensure that the movable door panel is pushed out first. This guide mechanism includes a guide wheel rotatably mounted on the sliding base and a guide wheel seat connected to the inner wall of the cabinet. A laterally extending guide groove is recessed at the end of the guide wheel seat, and both ends of this guide groove are open. Through the cooperation of the guide wheel and the guide groove, the movable door panel can slide laterally first, ensuring precise control of its movement trajectory. Furthermore, the guide mechanism allows the user to simply pull outwards to perform the push-out operation, avoiding the jamming or movement deviation of the movable door panel caused by operational errors in manual operation. This ensures smooth and accurate manual operation, improving the overall durability and service life of the lift cabinet.

[0040] Next, after the movable door panel is pulled outwards, the user pushes it upwards. At this point, the vertical sliding mechanism is passively activated. The vertical slider of the mechanism slides vertically along the vertical rail, moving the movable door panel upwards and opening it. The inner cabinet is now exposed, allowing the user to access the items stored inside. The movable door panel is now fully open. Notably, after the movable door panel is pulled outwards, the guide wheel of the guide mechanism has completely disengaged from the guide groove, passing through its open end. The guide wheel is externally positioned on the guide seat and does not affect the upward movement of the movable door panel. Simultaneously, the guide wheel continues to provide guidance, ensuring smooth movement of the movable door panel during its ascent and limiting its trajectory. The manual upward push operation is intuitive and easy to perform.

[0041] Compared to traditional lift cabinets that lack a manual opening mechanism, this lift cabinet features a push-out mechanism that allows users to quickly access the items inside under any circumstances. For example, in the event of a fire or a sudden power outage, users can still quickly retrieve emergency supplies, thus improving user safety.

[0042] In the aforementioned lifting cabinet, both manual and electric opening methods are available. A lifting block is installed on the lifting base of the lifting assembly. The lifting block connects to the pressing surface of the upper moving plate of the sliding seat, and the pressing surface rests on the inclined surface of the upper moving plate. During normal electric operation of the lifting cabinet, the transmission chain transmits the lifting power, which drives the sliding seat to rise and fall through the mounting base, providing outward and upward power to the movable door panel, thus achieving automated lifting and lowering of the cabinet door and providing users with a more convenient experience.

[0043] The dual-mode design not only significantly improves the reliability of the lifting cabinet, ensuring its functionality remains intact in various usage scenarios, but also overcomes the dependence on electricity inherent in traditional electric lifting cabinets, expanding their application range. The addition of a manual door opening method reduces the need for maintenance and replacement due to lifting component failures, allowing users to continue using the lifting cabinet even in the event of a malfunction. This reduces maintenance costs and losses from forced downtime, thus making it widely applicable.

[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
