Description

Technical Field

[0001] This utility model relates to the field of dressing table technology, and in particular to an intelligent lifting dressing table. Background Technology

[0002] Intelligent lift-up dressing tables are upgraded furniture that integrates traditional dressing tables with modern intelligent technology and electric lifting technology. Their core functions focus on makeup and storage of beauty and skin care products. With their flexible lifting function and diversified intelligent configuration, they significantly improve the convenience of use and space utilization, making them a popular category in the current home furnishing industry.

[0003] A search revealed the technical solution for "An Intelligent Lifting Dressing Table" with application number 201820926237.6. This solution mainly comprises a tabletop, a servo motor, a gear plate, a connecting slot, a partition, a switch, and a controller. It involves installing a dressing mirror within a storage slot, fixing both ends of the mirror with a vertical beam, and installing a rack on one side of the vertical beam that meshes with the gear plate of the servo motor. Through the circuit connection of the servo motor, controller, power supply box, and switch, the lifting and lowering action of the dressing mirror is controlled by the switch driving the motor. This allows the mirror to descend and retract into the storage slot of the side panel, thus protecting the dressing mirror and extending its lifespan.

[0004] In existing technical solutions, the lifting and lowering of such dressing tables relies solely on a servo motor to drive the dressing mirror, lacking multiple detection and active protection mechanisms for obstacles during the lifting process. When encountering situations such as protruding cosmetics or foreign objects (e.g., children touching them, or obstructions from debris) during the lifting process, the system cannot detect and trigger safety protection actions in a timely manner. This not only easily leads to damage to the mechanical structure but may also pose a safety threat to the user, seriously affecting the safety and reliability of the lifting dressing table in actual use. Summary of the Invention

[0005] The purpose of this invention is to provide an intelligent lifting dressing table that employs triple protection—motor current protection, a safety light curtain system, and mechanical limit switches—far exceeding the limitations of existing technologies that only offer single lifting control. When the upward movement encounters resistance, an abnormal motor current triggers a shutdown. When the downward movement encounters an object, the safety light curtain provides immediate feedback and drives the table to rise a short distance. The mechanical limit sensor also prevents overtravel, comprehensively mitigating the risks of squeezing and collisions, thus solving the problems mentioned in the background section.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an intelligent lifting dressing table, comprising a dressing cabinet body, a fingerprint switch installed at one end of the upper surface of the dressing cabinet body, a lifting cabinet movably installed on the rear side of the upper surface of the dressing cabinet body, a safety light curtain system installed at the outer edge of the front end of the lifting cabinet, and a lifting drive assembly provided on one side of the bottom end of the lifting cabinet.

[0007] The lifting drive assembly includes an assembly housing frame fixedly installed inside the bottom of the dressing cabinet. Mechanical limit sensors are provided at both the upper and lower ends of the assembly housing frame. A controller is also fixedly installed on the bottom surface of the assembly housing frame. A motor cover is fixedly installed at the middle position of the bottom inner side of the assembly housing frame. A motor is fixedly installed inside the motor cover. A lead screw is fixedly installed at the power output end of the motor.

[0008] Preferably, the lifting drive assembly further includes a first deep groove ball bearing with a retaining edge fixedly installed at the connection between the lead screw and the motor, a top fixing screw fixedly installed at the top end of the lead screw, and a second deep groove ball bearing with a retaining edge fixedly installed on the outside of the top end of the lead screw.

[0009] Preferably, a lead screw nut is sleeved on the outside of the lead screw, an intermediate push support frame is fixedly installed on the outer wall of the lead screw nut, and a sliding welded connecting plate is fixedly installed at the front end of the intermediate push support frame.

[0010] Preferably, a middle baffle fixedly mounted on the assembly housing frame is provided in front of the lead screw, and side baffles fixedly mounted on the assembly housing frame are provided on both the left and right sides of the middle baffle.

[0011] Preferably, a drawer is installed inside the front end of the dressing table, and a brown glass is installed at the front end of the upper surface of the dressing table.

[0012] Preferably, a makeup mirror is fixedly installed in the middle of the interior of the lifting cabinet, and a makeup refrigerator is fixedly installed on one side of the interior of the lifting cabinet.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This utility model adopts triple protection of "motor current protection, safety light curtain system, and mechanical limit", which far exceeds the design of existing technology that only has a single lifting control. When the upward movement encounters an obstacle, the motor current abnormality triggers a shutdown. When the downward movement encounters a foreign object, the safety light curtain provides immediate feedback and drives the machine to rise a certain distance. The mechanical limit sensor can also prevent overtravel, thus avoiding the risks of squeezing and collision in all aspects.

[0015] 2. The fingerprint switch of this utility model features an authentication design that prevents accidental operation by children or unauthorized use by others, protecting valuable cosmetic products inside the cabinet and solving the problem of existing technologies lacking an anti-accidental touch mechanism.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] This utility model provides a technical solution:

[0029] Please see Figure 1 , Figures 3 to 8 A smart lifting dressing table includes a dressing cabinet body 1. A fingerprint switch 2 is installed on one end of the upper surface of the dressing cabinet body 1. A lifting cabinet 5 is movably installed on the rear side of the upper surface of the dressing cabinet body 1. A safety light curtain system 8 is installed on the outer edge of the front end of the lifting cabinet 5. A lifting drive component 9 is provided on one side of the bottom end of the lifting cabinet 5. The lifting drive component 9 includes an assembly housing frame 901 fixedly installed inside the bottom end of the dressing cabinet body 1. Mechanical limit sensors 914 are provided at both the upper and lower ends of the assembly housing frame 901. A controller 913 is also fixedly installed on the bottom surface of the assembly housing frame 901. A motor cover 902 is fixedly installed in the middle position of the bottom end of the inner side of the assembly housing frame 901. A motor 903 is fixedly installed inside the motor cover 902. A lead screw 905 is fixedly installed at the power output end of the motor 903.

[0030] The lifting drive assembly 9 also includes a first deep groove ball bearing 904 with a flange fixedly installed at the connection between the lead screw 905 and the motor 903. A top fixing screw 909 is fixedly installed at the top of the lead screw 905, and a second deep groove ball bearing 910 with a flange fixedly installed on the outside of the top of the lead screw 905. The second deep groove ball bearing 910 is sleeved on the outside of the top of the lead screw 905 to limit the radial wobble of the lead screw and ensure smooth rotation. The top fixing screw 909 is locked to the top of the lead screw by threads, and axial pressure is applied from above the bearing to firmly fix the bearing in the preset mounting position of the assembly housing 901, so as to prevent the bearing from being damaged when the lead screw rotates or when the lifting cabinet 5 is under load. In case of axial displacement, to ensure the stability of the transmission structure, a screw nut 906 is sleeved on the outside of the screw nut 905. An intermediate push support frame 907 is fixedly installed on the outer wall of the screw nut 906. A sliding welded connecting plate 908 is fixedly installed at the front end of the intermediate push support frame 907. The sliding welded connecting plate 908 is fixedly connected to the bottom end of the lifting cabinet 5. An intermediate baffle 912 is fixedly installed on the assembly housing frame 901 in front of the screw 905. Side baffles 911 are fixedly installed on the assembly housing frame 901 on both the left and right sides of the intermediate baffle 912. The side baffles 911 are slidably connected to the sliding welded connecting plate 908.

[0031] By adopting the above technical solution, during use, the user completes identity verification by operating the fingerprint switch 2, and the signal is transmitted to the controller 913, activating the lifting function. After receiving the lifting command, the controller 913 sends a start signal to the motor 903 in the lifting drive assembly 9, and the motor 903 starts to run. The power output end of the motor 903 drives the lead screw 905 to rotate. The first and second deep groove ball bearings 904 and 910 respectively fix the upper and lower ends of the lead screw 905 to ensure its stable rotation. When the lead screw 905 rotates, the lead screw nut 906 sleeved on its outside moves linearly upward or downward along the axis of the lead screw 905, and drives the intermediate push support frame 907 fixed on the outer wall of the nut to move synchronously. The intermediate push support frame 907 is connected to the lifting cabinet 5 through the sliding welded connecting plate 908, thereby driving the lifting cabinet 5 to slide up and down along the track of the side baffle 911. The intermediate baffle 912 can play an auxiliary guiding role to realize the lifting action.

[0032] When the lifting cabinet 5 encounters an obstruction during its ascent, the increased lifting resistance causes an abnormal rise in the current of motor 903. Upon detecting this abnormal current, controller 913 immediately commands motor 903 to stop. Simultaneously, mechanical limit sensors 914, mounted on the upper and lower ends of the housing frame 901, assist in monitoring the lifting limit position to prevent overtravel. It should be noted that controller 913 has a built-in current detection module, or monitors the operating current of motor 903 in real time via a current sensor connected in series with motor 903. When the current exceeds a preset threshold (e.g., 1.5-2 times the rated current) and persists for a certain period (e.g., 0.5 seconds), it is determined to be an obstruction, preventing false triggering of protection due to instantaneous current fluctuations. After motor 903 stops, controller 913 triggers an alarm via buzzer or indicator light. After the user removes the obstruction, the lifting command is triggered again via fingerprint switch 2, and the system resumes operation.

[0033] During the descent of the lifting cabinet 5, if the safety light curtain system 8, installed at the front edge of the lifting cabinet 5, detects protruding cosmetics or foreign objects intruding, it immediately sends a signal to the controller 913. The controller 913 instructs the motor 903 to reverse, driving the lifting cabinet 5 to rise a certain distance to avoid crushing the obstacle, and then maintains a stopped state until the obstacle is cleared. When the lifting cabinet 5 reaches the target position or the user triggers a closing command, the mechanical limit sensor 914 detects the position signal and feeds it back to the controller 913. The controller 913 instructs the motor 903 to stop operating, and the lifting action is completed. This utility model adopts triple protection of "motor 903 current protection, safety light curtain system 8, and mechanical limit", far exceeding the design of existing technologies that only have single lifting control. When the upward movement encounters an obstacle, the motor 903 is triggered to stop due to abnormal current. When the downward movement encounters a foreign object, the safety light curtain provides immediate feedback and drives the cabinet to rise a certain distance. The mechanical limit sensor 914 can also prevent overtravel, comprehensively avoiding the risk of crushing and collision. The fingerprint switch 2's identity verification design prevents children from accidentally operating it or others from using it at will, protecting valuable cosmetics inside the cabinet and solving the problem of existing technologies lacking an anti-accidental touch mechanism. The lifting drive component 9 is integrated into the assembly housing 901. The modular design makes the internal structure compact and orderly, without taking up extra dressing space. Compared with the distributed layout of existing technologies, it is more conducive to overall size optimization.

[0034] Specifically, such as Figure 1 and Figure 2 As shown, a drawer 3 is installed inside the front end of the dressing cabinet 1, a brown glass 4 is installed at the front end of the upper surface of the dressing cabinet 1, a makeup mirror 6 is fixedly installed in the middle of the interior of the lift cabinet 5, and a makeup refrigerator 7 is fixedly installed on one side of the interior of the lift cabinet 5.

[0035] By adopting the above technical solution, drawer 3 can be opened by gently pulling its handle. Makeup brushes, eyeshadow palettes, blushes, and other room-temperature cosmetics can be categorized and placed in the compartments within drawer 3. After use, drawer 3 can be gently pushed to close completely. The amber glass 4 at the top front of the vanity cabinet 1 serves both decorative and practical purposes, providing a temporary place for currently used cosmetics such as foundation and lipstick. Its amber material effectively conceals any wiring or structural elements below, enhancing the product's appearance. Simultaneously, the smooth glass surface is easy to clean, preventing makeup residue from contaminating the cabinet. The makeup mirror 6 is fixed in place. Installed in the middle of the lifting cabinet 5, the mirror faces the user's face when the cabinet is raised. Its angle is preset and optimized to meet the makeup needs of the front and side of the face. After the lifting cabinet 5 is raised, the makeup refrigerator 7 is powered on synchronously with the system. Some models can be started by triggering the fingerprint switch 2. The refrigerator has a temperature adjustment button on the side, which can be adjusted according to the needs of the items. It is recommended to set the general beauty refrigeration temperature to 5-10℃. The mask heating function can be turned on by a separate button. The default heating temperature is 38℃, which is a suitable temperature for the human body. The heating time is about 3-5 minutes.

[0036] Working Principle: In use, lightly press the fingerprint switch 2 on the upper surface of the dressing cabinet 1 with your registered fingerprint. After hearing a "beep" confirmation sound, fingerprint verification is successful, and the system activates the lifting function. At the same time, the safety light curtain system 8 at the front of the lifting cabinet 5 starts simultaneously, with the light flashing slightly to indicate readiness. After successful fingerprint verification, the system defaults to triggering the lifting action of the lifting cabinet 5. For some models, the lifting direction can be switched by briefly pressing the fingerprint switch 2. During the lifting process, the motor 903 in the lifting drive assembly 9 drives the lead screw 905 to rotate. Through the cooperation of the lead screw nut 906 and the intermediate push support frame 907, the lifting cabinet 5 is driven to rise smoothly along the guide structure. At this time, be careful to observe the surroundings and avoid putting your hands or other objects into the area below the lifting cabinet 5. When the lifting cabinet 5 rises to the preset height, it is precisely controlled by the mechanical limit sensors 914 at the upper and lower ends of the mounting frame 901, and the system automatically stops. At this time, the makeup mirror 6 is fully extended for easy grooming. If an obstruction is encountered during the ascent, the current of the motor 903 will rise abnormally, and the controller 913 will immediately command the motor 903 to stop and issue an alarm. After the obstruction is cleared, the lifting cabinet can be triggered again by the fingerprint switch 2. After use, lightly press the fingerprint switch 2 to trigger the closing command, and the lifting cabinet 5 will begin to descend smoothly. During the descent, the safety light curtain system 8 monitors the lifting path in real time. If cosmetics protruding, foreign objects intruding, or human touch is detected, a signal will be immediately sent to the controller 913. The controller 913 will command the lifting cabinet 5 to pause and rise 5-10cm. After the obstruction is cleared, the closing command can be triggered again to complete the storage. After closing, the lifting cabinet 5 is flush with the upper surface of the dressing cabinet 1, and the tinted glass 4 enhances the overall aesthetics.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
