Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, specifically to a concealed lifting mechanism. Background Technology

[0002] In various automated equipment, smart furniture, or display devices, lifting mechanisms are often used to achieve height adjustment or concealed storage functions for components. Their performance directly affects the user experience and space utilization of the equipment. To achieve stable lifting, existing lifting mechanisms typically include a drive component and a lifting component, but these are often installed separately or connected through complex external transmission components.

[0003] Specifically, the drive unit is typically installed independently at the equipment base, while the lifting unit is located at the main body that needs to be raised or lowered. Power is transmitted between the two via a long drive rod or chain. Because the drive and lifting units are separate and the transmission path is long, the coordination between the components during lifting is poor, making precise synchronous control difficult. Especially during frequent lifting operations, problems such as loosening of the transmission components and low power transmission efficiency can easily occur, leading to uneven lifting speeds, unstable operation, and even shaking or jamming. Furthermore, the exposed transmission structure not only occupies space and poses safety hazards, but also affects the overall aesthetics and concealment of the equipment, failing to meet the modern equipment's requirements for compact structure, stable operation, and a simple appearance.

[0004] Existing lifting mechanisms suffer from problems such as poor coordination, insufficient space occupation, and inadequate concealment due to the separate installation of components, which in turn affects the functionality and practicality of the lifting mechanism. Therefore, there is an urgent need for a concealed lifting mechanism. Utility Model Content

[0005] The purpose of this application is to provide a concealed lifting mechanism to solve the problems of poor coordination, space occupation and insufficient concealment that may be caused by the separate installation of components in the existing lifting mechanism, which in turn affects the functionality and practicality of the equipment.

[0006] One embodiment of this utility model provides a concealed lifting mechanism, including a device housing and a lifting component installed inside the device housing;

[0007] The lifting assembly includes a driving component, a connecting component, and a lifting component. The driving component is connected to the lifting component through the connecting component and drives the lifting component to move up and down through the connecting component.

[0008] The lifting component includes a limiting rod and a lifting plate. The lifting plate is movably mounted on the limiting rod. A first transmission structure is provided on the connecting member, and a second transmission structure is provided on the lifting plate. The connecting member is movably connected to the second transmission structure of the lifting plate through the first transmission structure. The first transmission structure and the second transmission structure together form a helical transmission structure.

[0009] It should be noted that the connecting component can be a lead screw, and the first transmission structure on the lead screw and the second transmission structure on the lifting plate can be mutually compatible threaded structures, which together constitute a helical transmission structure that can convert the rotation effect of the lead screw into the lifting effect of the lifting plate. That is, the connecting component can achieve the lifting effect of the lifting component through the mutual cooperation of the first transmission structure and the second transmission structure under the drive of the driving component.

[0010] In this solution, the drive component, connector, and lifting component are integrated and installed inside the equipment housing. The drive component is connected to the lifting component via the connector, enabling the drive component to drive the lifting component to perform lifting movements. On the one hand, this avoids the problem of poor coordination caused by long transmission paths and scattered component installation, ensuring that the lifting component runs smoothly and at a uniform speed during the lifting process, eliminating shaking and jamming. On the other hand, it changes the traditional mode of separate installation of lifting mechanism components, allowing each component to fit tightly together inside the equipment housing, effectively reducing space occupation and greatly improving the concealment of the overall structure.

[0011] Specifically, the lifting plate of the lifting component is movably mounted on the limit rod. The connecting piece and the lifting plate are respectively provided with a first transmission structure and a second transmission structure, which together form a spiral transmission structure that can stably convert the power of the driving component into the lifting motion of the lifting plate. The limit rod limits the movement of the lifting plate and can cooperate with the limit plate set inside the equipment housing to further control the stability and accuracy of the lifting motion.

[0012] Therefore, this concealed lifting mechanism effectively solves the problems of poor coordination, insufficient space occupation and concealment that may exist in existing lifting mechanisms, and improves the functionality and practicality of the lifting mechanism.

[0013] In one embodiment, the drive component includes a drive motor, a reducer, and a coupling. The drive motor is connected to the reducer, and the reducer is connected to the connecting member via the coupling.

[0014] In one embodiment, the first transmission structure and the second transmission structure are mutually compatible threaded structures.

[0015] In one embodiment, a copper sleeve is fixedly installed on the lifting plate, and the inner wall of the copper sleeve is the second transmission structure.

[0016] In this solution, the drive component, consisting of a drive motor, a reducer, and a coupling, enables the output shaft of the drive motor to have its speed and torque adjusted by the reducer, and then the power is stably transmitted to the connecting parts by the coupling, ensuring smooth lifting power and improving operational coordination. Additionally, the first and second transmission structures use compatible threads to form a precise helical transmission, accurately controlling the displacement of the lifting plate and improving lifting accuracy and reliability. Furthermore, the copper sleeve on the lifting plate is selected as the second transmission structure, utilizing the wear-resistant and self-lubricating properties of copper to reduce friction loss, extend the life of the transmission structure, reduce maintenance costs, and further enhance lifting smoothness.

[0017] In one embodiment, at least two limiting plates are also provided inside the device housing, with the two limiting plates located above and below the lifting plate, respectively.

[0018] In one embodiment, the connector is provided with a necking structure corresponding to the position of the limiting plate, and a bearing is installed on the limiting plate corresponding to the necking structure.

[0019] In one embodiment, a limiting hole is provided on the limiting plate located above the lifting plate, the limiting hole being used to limit the radial movement of the limiting rod that may occur during the lifting process.

[0020] In this design, by setting at least two limiting plates inside the equipment housing, above and below the lifting plate, clear limiting boundaries can be established for the lifting movement of the lifting plate, preventing excessive displacement during lifting. Additionally, the necking structure of the connecting piece corresponding to the limiting plate position, in conjunction with the bearing installed on the limiting plate, ensures stable axial positioning of the connecting piece during rotation, further reducing transmission errors caused by connecting piece wobbling and ensuring the accuracy and stability of power transmission. Furthermore, the limiting hole on the limiting plate above the lifting plate restricts the radial movement of the limiting rod during lifting, further constraining the movement trajectory of the lifting plate and preventing problems such as offset or jamming of the lifting components during lifting. The aforementioned structural designs work together to enhance the stability and reliability of the concealed lifting mechanism, improving its functionality and practicality.

[0021] In one embodiment, the upper cover of the device housing is fixedly connected to the end of the limiting rod.

[0022] In this solution, by fixing the upper cover of the equipment housing to the end of the limiting rod, a stable connection is formed between the upper cover and the lifting component. This allows the upper cover to rise and fall smoothly and synchronously with the limiting rod during the operation of the lifting mechanism. This connection method allows users to add various processing components to the upper cover, such as detection sensors, material gripping mechanisms, or other functional components. These components enable functions such as monitoring the status of the space above or the position of materials, or gripping and placing materials during the lifting process. This allows the upper cover to collaboratively complete multiple processing steps during lifting, improving the expandability and practicality of the lifting mechanism to meet diverse processing needs.

[0023] In one embodiment, the lower end cover of the device housing is provided with a connection port, and the drive component extends from the connection port.

[0024] In this design, a connection port is provided on the lower end cover of the equipment housing, allowing the drive component to extend from this port and enabling convenient connection between the drive component and an external power supply or control system. This design maintains the integrity and concealment of the internal structure of the equipment housing while providing an external connection channel for the drive component. In addition, the connection port design on the lower end cover facilitates the installation and maintenance of the drive component. When the drive component needs to be inspected or replaced, it is not necessary to disassemble the entire equipment housing. Maintenance personnel can directly install and maintain the drive component through this connection port, reducing maintenance difficulty and cost.

[0025] In one embodiment, a mounting base is provided around the bottom of the device housing.

[0026] In this solution, by setting mounting bases around the bottom of the equipment housing, the stability of the concealed lifting mechanism can be ensured, and it can be flexibly installed on various surfaces. Attached Figure Description

On the one hand, this avoids the problem of poor coordination caused by long transmission paths and scattered component installation, ensuring that the lifting component 4 runs smoothly and at a uniform speed during the lifting process, eliminating shaking and jamming. On the other hand, it changes the traditional mode of separate installation of lifting mechanism components, allowing each component to fit tightly together inside the equipment housing 1, effectively reducing space occupation and greatly improving the concealment of the overall structure.
