Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of storage cabinets, in particular to an intelligent lifting storage cabinet based on voice recognition. BACKGROUND

[0002] In small-sized residential or multifunctional composite spaces (such as living rooms combined with study rooms, balconies combined with storage areas), space utilization is one of the core demands of users. The existing storage cabinets are mostly of fixed height and integrated structure, with single function and fixed space occupation: the bottom area cannot be flexibly released when idle, resulting in space waste; and in balcony scenarios, the bottom of the storage cabinet is often occupied by items such as robot sweepers and folding chairs, which also blocks the storage cabinet and affects the convenience of accessing items.

[0003] To improve space utilization, some liftable storage cabinets have emerged, but some cabinets with lifting function need to be manually controlled, and a few liftable storage cabinets rely on manual buttons or remote control, which cannot quickly trigger the lifting operation when the user's hands are occupied (such as holding cleaning tools, books and sundries), and the convenience of use is insufficient. Therefore, there is an urgent need for an intelligent storage cabinet with overall lifting function and voice control, which can realize the lifting of the cabinet body through voice instructions, release the bottom space for activities or placing other items when idle, and lower the cabinet body for convenient access when storing, realizing the space superposition utilization of "one cabinet with multiple uses", adapting to the use demand of small-sized and multifunctional spaces, and improving the space utilization and convenience of use. SUMMARY

[0004] (I) Technical problems solved

[0005] In view of the shortcomings of the prior art, the present application provides an intelligent lifting storage cabinet based on voice recognition, which is a voice-controlled lifting storage cabinet that can operate the overall lifting of the cabinet body through voice control when in use, is convenient to use, and releases the bottom space when idle, and lowers it when storing, solving the problem of inconvenient and inflexible lifting control of the existing storage cabinet.

[0006] (II) Technical solutions

[0007] The present application specifically adopts the following technical solutions to achieve the above-mentioned purposes:

[0008] A voice recognition-based intelligent lift-up locker includes a base and a locker body. A column is bolted to the upper surface of the base. A T-shaped groove is formed along the length of one side of the column, and a T-shaped slider is slidably connected to the T-shaped groove. Two symmetrically distributed L-shaped connecting plates are bolted to the T-shaped slider, and a support plate is fixedly connected to one side of each L-shaped connecting plate. Two locker bodies are provided, each fixed to a corresponding support plate. A voice-activated lift-up control component for controlling the lifting of the T-shaped slider and the locker body is fixedly connected to the upper surface of the base. The voice-activated lift-up control component includes a bracket fixedly connected to the upper surface of the base, and a microphone array is embedded in an inclined plate at the top of the bracket.

[0009] Furthermore, a lead screw is rotatably connected to the T-shaped groove of the column, and a screw hole adapted to the lead screw is opened at the T-shaped slider corresponding to the lead screw. A motor is installed on the lower surface of the base, and the output shaft of the motor is coaxially connected and fixed to the lead screw.

[0010] Furthermore, a control box is fixedly connected to one side of the support of the voice lifting control component. The control box includes a housing fixedly connected to one side of the support, and a voice preprocessing module, a voice recognition chip, and a main control module respectively installed inside the housing. The microphone array is used to collect user voice signals. The voice preprocessing module is electrically connected to the microphone array and is used to perform noise reduction and amplification processing on the collected voice signals. The voice recognition chip is electrically connected to the voice preprocessing module and is used to convert the processed voice signals into digital instructions. The main control module is electrically connected to the voice recognition chip and the motor respectively, and is used to receive the digital instructions from the voice recognition chip and control the operation of the motor, drive the lead screw to rotate, and then control the lifting of the storage cabinet body.

[0011] Furthermore, a storage battery is installed inside the enclosure, and the voice preprocessing module, voice recognition chip, main control module, and motor are all connected in parallel to the storage battery.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example

[0026] like Figures 1-6As shown in the figure, an embodiment of the present invention proposes a smart lifting locker based on voice recognition, including a base 1 and a locker body 3. A column 2 is fixedly connected to the upper surface of the base 1 by bolts. A T-shaped groove 6 is formed on one side of the column 2 along its length direction, and a T-shaped slider 8 is slidably connected to the T-shaped groove 6. Two symmetrically distributed L-shaped connecting plates 9 are fixedly connected to the T-shaped slider 8 by bolts, and a support plate 10 is fixedly connected to one side of each L-shaped connecting plate 9. The locker body 3 is provided with two of them and is fixed to the corresponding support plate 10. A voice lifting control component 4 for controlling the lifting of the T-shaped slider 8 and the locker body 3 is fixedly connected to the upper surface of the base 1. The voice lifting control component 4 includes a bracket 401 fixedly connected to the upper surface of the base 1, and a microphone array 404 is embedded in the inclined plate 403 set on the top of the bracket 401.

[0027] It should be noted that the base 1, as the supporting base of the entire device, is fixed to the column 2 with bolts to ensure that the column 2 has stable support strength and provides a stable mounting carrier for the subsequent lifting structure. The T-shaped sliding groove 6 on the column 2 and the T-shaped slider 8 form a sliding engagement mechanism. Its T-shaped structure can prevent the slider from shifting or falling off during the sliding process. The T-shaped slider 8 is connected to the L-shaped connecting plate 9 by bolts, and then the connecting plate fixes the support plate 10. Finally, the storage cabinet body 3 is supported on the support plate 10, which provides the structural foundation for the subsequent lifting movement of the storage cabinet. At the same time, the voice lifting control component 4 fixed on the base 1 is the core module for realizing intelligent control. The microphone array 404 embedded in the inclined plate 403 on the top of its bracket 401 can optimize the voice acquisition range by tilting the angle to ensure accurate capture of the user's voice control commands, providing the signal input basis for subsequent voice recognition and lifting control triggering.

[0028] like Figure 1 and Figure 2 As shown, in some embodiments, a lead screw 7 is rotatably connected to the T-shaped groove 6 of the column 2, and a screw hole adapted to the lead screw 7 is opened on the T-shaped slider 8 corresponding to the lead screw 7. A motor 11 is installed on the lower surface of the base 1, and the output shaft of the motor 11 is coaxially connected and fixed to the lead screw 7.

[0029] It should be noted that the lead screw 7 rotatably connected in the T-shaped groove 6 on the column 2 and the matching screw hole on the T-shaped slider 8 constitute a screw transmission mechanism. This mechanism converts the rotational motion output by the motor 11 into the linear lifting motion of the slider. The motor 11 installed on the lower surface of the base 1 serves as a power source, and its output shaft is coaxially fixed with the lead screw 7 to ensure that the torque of the motor 11 can be directly transmitted to the lead screw 7. When the motor 11 receives a control signal to start, the output shaft drives the lead screw 7 to rotate synchronously. Since the lead screw 7 and the T-shaped slider 8 are engaged by the screw hole thread, and the slider is limited by the T-shaped groove 6 and cannot rotate with the lead screw 7, the rotational motion of the lead screw 7 is converted into the up-and-down sliding of the T-shaped slider 8 along the length of the groove, thereby driving the L-shaped connecting plate 9, the support plate 10 and the storage cabinet body 3 connected to the slider to complete the lifting action, realizing the transmission of lifting power and the conversion of motion form.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, in some embodiments, a control box 402 is fixedly connected to one side of the bracket 401 of the voice lifting control component 4. The control box 402 includes a box body 4021 fixedly connected to one side of the bracket 401, and a voice preprocessing module 4022, a voice recognition chip 4023, and a main control module 4025 respectively installed inside the box body 4021. The microphone array 404 is used to collect user voice signals. The voice preprocessing module 4022 is electrically connected to the microphone array 404 and is used to perform noise reduction and amplification processing on the collected voice signals. The voice recognition chip 4023 is electrically connected to the voice preprocessing module 4022 and is used to convert the processed voice signals into digital instructions. The main control module 4025 is electrically connected to the voice recognition chip 4023 and the motor 11 respectively and is used to receive the digital instructions of the voice recognition chip 4023 and control the motor 11 to run, drive the lead screw 7 to rotate, and then control the lifting of the storage cabinet body 3.

[0031] It should be noted that the control box 402 serves as the control center, with its internal modules forming a collaborative signal link: First, the microphone array 404 acts as the voice signal acquisition end, capturing in real time the user's voice commands for raising and lowering the locker (such as "raise the locker" or "lower the locker"), and transmitting the acquired analog voice signal to the voice preprocessing module 4022. The voice preprocessing module 4022 is electrically connected to the microphone array 404, performing noise reduction (filtering environmental noise, such as dust, wind noise, and the sound of other objects colliding) and amplification on the acquired raw voice signal to improve the clarity and stability of the voice signal, ensuring subsequent recognition. Accuracy: The processed voice signal is transmitted to the voice recognition chip 4023, which converts the analog voice signal into digital commands that can be recognized by the main control module 4025. The main control module 4025, as the core control unit, is associated with the voice recognition chip 4023 and the motor 11 respectively. After receiving the digital commands, it parses them to determine whether the user's request is "raise" or "lower" and sends the corresponding control signal (forward rotation or reverse rotation signal) to the motor 11. After receiving the signal, the motor 11 starts and rotates in the specified direction, driving the lead screw 7 to rotate, and driving the T-shaped slider 8 and the storage cabinet body 3 through the screw transmission mechanism to complete the corresponding lifting and lowering action.

[0032] like Figure 4 and Figure 5 As shown, in some embodiments, a storage battery 4024 is installed inside the housing 4021, and the voice preprocessing module 4022, the voice recognition chip 4023, the main control module 4025 and the motor 11 are all connected in parallel to the storage battery 4024.

[0033] It should be noted that the battery 4024 installed inside the housing 4021 serves as an independent power source, providing power support for the entire intelligent lifting system.

[0034] like Figure 5 As shown, in some embodiments, support legs 5 are fixedly connected to the four corners of the lower surface of the base 1, and the lower ends of the support legs 5 extend to the bottom of the motor 11.

[0035] It should be noted that the support legs 5 at the four corners of the lower surface of the base 1 serve as the support structure of the equipment. Their core function is to evenly distribute the weight of the entire equipment to the four support points, improve the stability of the equipment when placed on the ground, and prevent the equipment from tipping over due to uneven ground or vibration during operation. At the same time, the lower end of the support legs 5 extends to the bottom of the motor 11, forming a protective structure for the motor 11. The height of the support legs 5 is higher than that of the motor 11, so that the motor 11 is suspended in the air, preventing the motor 11 from directly contacting the ground.

[0036] like Figure 1As shown, in some embodiments, a cabinet door is rotatably connected to one side of the cabinet body 3 via a hinge, and a mushroom-shaped handle is fixedly connected to the cabinet door.

[0037] It should be noted that by installing mushroom-shaped handles on the cabinet doors, it is convenient to open or close the doors, thereby facilitating the storage of items.

[0038] The working principle and usage steps of this invention are as follows: First, the user issues a voice command for lifting control (such as "raise the locker" or "lower the locker"). The microphone array 404 captures the voice signal and transmits it to the voice preprocessing module 4022. The voice preprocessing module 4022 reduces noise and amplifies the signal, and then the voice recognition chip 4023 converts it into a digital command. The main control module 4025 parses the digital command and sends a forward or reverse rotation signal to the motor 11. Then, the motor 11 starts and drives the lead screw 7 to rotate. Through the screw transmission, the T-shaped slider 8 slides up and down along the T-shaped groove 6. The T-shaped slider 8 drives the locker body 3 to complete the corresponding lifting action through the L-shaped connecting plate 9 and the support plate 10. After reaching the target height, the motor 11 stops running.

[0039] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
