Description

Technical Field

[0001] This utility model belongs to the field of cabinet technology, specifically a hanging basket with hand sweeping sensor and touch switch. Background Technology

[0002] Corner cabinets, as a key design element in optimizing 90° corner space in kitchens and storage systems, are typically equipped with linked rotating pull-out baskets to improve space utilization. These pull-out baskets (such as "little monsters" or "flying saucers") achieve automatic rotation after being pulled out through the coordinated action of guide rail mechanisms, rotating brackets, and linkage devices. Their unique feature is that, due to the characteristics of rotational motion, the door panel and rotating bracket are usually installed on only one side. This design stems from the spatial limitations and motion trajectory requirements of the rotating mechanism, but it brings a series of technical problems: First, single-sided fixing leads to uneven stress on the door panel during rotation, easily causing deformation or loosening; second, precise calibration of the relative position of the door panel and the rotation center is required during installation, otherwise rotational interference or collision with the cabinet may occur; third, existing single-sided fixing structures mostly use screw fastening, which is not only time-consuming to install but also difficult to fine-tune, making it difficult to control the gap between the door panel and the cabinet.

[0003] Existing door panel installation structures have significant drawbacks: traditional screw fixing methods are cumbersome, requiring repeated adjustments and lacking quick disassembly; the lack of standardized quick-installation designs makes door panel alignment difficult, leading to misalignment; furthermore, existing structures have poor adaptability to door panel thicknesses and are incompatible with different brands of pull-out basket systems. These problems manifest specifically as: installers need multiple trial installations to determine the appropriate fixing position; screw loosening due to unilateral stress during use necessitates frequent maintenance; and different installation accessories are required for door panels of varying thicknesses, increasing production and inventory costs. These technical bottlenecks severely restrict product installation efficiency and user experience, impacting market promotion effectiveness.

[0004] A deeper problem lies in the fact that existing single-sided installation structures cannot meet the dual demands of modern kitchen cabinets for ease of installation and stability in use. On the one hand, consumers expect a quick-installation experience; on the other hand, the unique nature of rotational movement requires the installation structure to possess sufficient rigidity and durability. This contradiction has not been well resolved in existing technologies, resulting in most linked rotating pull-out basket products on the market either sacrificing ease of installation to ensure stability or simplifying the structure but affecting its lifespan. This technological dilemma urgently needs to be overcome through innovative quick-installation structures to achieve a dual improvement in installation efficiency and performance. Summary of the Invention

[0005] The purpose of this invention is to overcome the problems of low accuracy and poor user experience of the touch switches used in current lifting baskets, and to provide a basket with hand-scanning sensing and touch switch.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A suspended platform with hand-scanning sensing and touch switches includes a support frame, a lifting drive device, and a control system. The support frame is equipped with a sensing unit. The lifting drive device is connected to the support frame and drives the support frame to lift. The control system includes a sensing module and a main control module. The sensing module, located on the sensing unit, includes a microcontroller, an electrode touch switch, an infrared emitting circuit, and an infrared receiving circuit. The microcontroller has a control interface, a gesture detection interface, a touch detection interface, and a transmission interface. It is electrically connected to the electrode touch switch via the touch detection interface, to the infrared emitting circuit via the control interface, to the infrared receiving circuit via the gesture detection interface, and to the main control module via the transmission interface. The main control module is also electrically connected to the lifting drive device to control its operation.

[0007] This invention significantly improves the operational reliability of the suspended platform in complex environments such as dampness and oil contamination by integrating a dual-mode sensing system that combines infrared gesture sensing and capacitive touch control. Users can choose between single-mode or dual-mode operation based on their needs and operating habits. In dual-mode operation, both infrared gesture sensing and touch sensing are triggered simultaneously, avoiding accidental touches caused by wet hands or oil when only touch switch functionality is available. The sensing area is also expanded, allowing for sensitive response without requiring precise, continuous touches. The microcontroller processes infrared and capacitive signals through multi-port collaborative processing, achieving complementary optimization of rapid gesture control and precise touch operation. This solves the inconvenience of traditional thin electrode operation and overcomes the risk of failure in high-interference scenarios such as kitchens and bathrooms with a single touch mode, making the lifting control both environmentally adaptable and easy to operate.

[0008] Furthermore, the sensing unit is located at the bottom of the support frame and includes a base plate and a top cover. The base plate has a mounting groove with an opening at the top, and the top cover is placed on the mounting groove. The sensing module is located inside the mounting groove. The infrared emitting circuit has an infrared emitter, and the infrared receiving circuit has an infrared receiver. The infrared emitter and the infrared receiver are fixedly installed on the bottom surface of the mounting groove. The base plate has a first through hole through the bottom wall corresponding to the optical axis outlet of the infrared emitter, and a second through hole through the bottom wall corresponding to the optical axis inlet of the infrared receiver.

[0009] Furthermore, the electrode touch switch is disposed on the outer bottom wall of the substrate, and located between the first through hole and the second through hole. In this solution, when a finger touches the sensing area, the infrared emitter emits a portion of infrared light, which is reflected by the finger and received by the infrared receiver, thereby triggering an infrared sensing signal and simultaneously triggering a capacitance change signal.

[0010] Alternatively, the first and second through holes are oblique holes, so that the optical axis of the infrared transmitter and the optical axis of the infrared receiver form a V-shaped spatial angle. The electrode touch switch is disposed on the outer bottom wall of the substrate and is located in the area where the two optical axes intersect.

[0011] Furthermore, the sensing module includes an infrared emitting diode and a switching diode. One end of the infrared emitting diode is connected to a power supply, and the other end is grounded to form the infrared emitting circuit. The switching diode is connected in series with the infrared emitting circuit and connected to the control interface. The microcontroller controls the switching diode by sending a level signal to control the infrared emitting circuit.

[0012] Furthermore, the infrared emitting circuit also includes a first current-limiting resistor, the switching transistor is an NPN transistor, the current input terminal of the infrared emitting transistor is connected to the positive power supply through the first current-limiting resistor, its current output terminal is connected to the collector of the switching transistor, the base of the switching transistor is connected to the control interface, and the emitter is grounded.

[0013] Furthermore, the sensing module includes an infrared receiver and a pull-up resistor. Its signal output terminal is connected to the gesture detection interface and simultaneously connected to the positive power supply via the pull-up resistor. The positive power supply terminal is connected to the positive power supply, forming an infrared receiving circuit. In this scheme, when no infrared signal is detected, the infrared receiving circuit maintains a high level through the pull-up resistor. When a valid infrared signal is detected, the output terminal of the receiver changes from high to low. The microcontroller identifies the signal and executes corresponding control by detecting this level change.

[0014] Furthermore, the sensing electrode of the electrode touch switch is circular with a diameter ranging from 10mm to 20mm.

[0015] Furthermore, the microcontroller includes a timing module and a storage module. The microcontroller records the current state and current mode of the support frame through the storage module. The microcontroller records the trigger duration of the electrode touch switch at regular intervals through the timing module. The microcontroller has a working mode and a sleep mode. When the trigger duration reaches the preset duration, the sensing module switches between the working mode and the sleep mode.

[0016] Furthermore, when the sensing module enters sleep mode, the microcontroller disconnects the infrared emitting circuit through the control interface. Attached Figure Description

[0021] See Figure 1-4 As shown, this embodiment discloses a suspended basket 1 with hand-scanning sensing and touch switch, including a support frame 2, a lifting drive device, and a control system. The support frame 2 is equipped with a sensing unit 43. The lifting drive device is connected to the support frame 2 for driving the support frame 2 to rise and fall. The control system includes a sensing module and a main control module. The sensing module is located on the sensing unit 43 and includes a microcontroller MCU1, an electrode touch switch K1, an infrared emitting circuit, and an infrared receiving circuit. The microcontroller MCU1 has a control interface, a gesture detection interface, a touch detection interface, and a transmission interface. It is electrically connected to the electrode touch switch K1 through the touch detection interface, to the infrared emitting circuit through the control interface, to the infrared receiving circuit through the gesture detection interface, and to the main control module through the transmission interface. The main control module is also electrically connected to the lifting drive device to control its operation. In practical applications, the microcontroller implements dual-signal input functionality through internal logic circuits. For example, the microcontroller has an OR gate circuit, and the two input terminals of the OR gate circuit are connected to the infrared detection interface and the touch detection interface.

[0022] The aforementioned sensing unit 43 is located at the bottom of the support frame 2, and includes a substrate 431 and a top cover 432. The substrate 431 has a mounting groove with an opening at the top, and the top cover 432 covers the mounting groove. The sensing module is located in the mounting groove. The infrared emitting circuit has an infrared transmitter FS1, and the infrared receiving circuit has an infrared receiver IRM1. The infrared transmitter FS1 and the infrared receiver IRM1 are fixedly installed on the bottom surface of the mounting groove. The substrate 431 has a first through hole through the bottom wall corresponding to the optical axis outlet of the infrared transmitter FS1, and a second through hole through the bottom wall corresponding to the optical axis inlet of the infrared receiver IRM1.

[0023] The aforementioned electrode touch switch K1 is disposed on the outer bottom wall of the substrate 431, and located between the first through hole and the second through hole. In this scheme, when a finger touches the touch electrode switch, the infrared emitter FS1 emits a portion of infrared light, which is reflected by the finger and received by the infrared receiver IRM1, thereby triggering an infrared sensing signal and simultaneously triggering a capacitance change signal.

[0024] The first and second through holes are oblique holes, so that the optical axis of the infrared transmitter FS1 and the optical axis of the infrared receiver IRM1 form a V-shaped spatial angle. The electrode touch switch K1 is disposed on the outer bottom wall of the substrate 431 and is located in the area where the two optical axes intersect.

[0025] The aforementioned sensing module includes an infrared emitting diode and a switching diode. One end of the infrared emitting diode is connected to a power supply, and the other end is grounded to form the infrared emitting circuit. The switching diode is connected in series with the infrared emitting circuit and is connected to the control interface. The microcontroller MCU1 controls the switching diode by sending a level signal to control the infrared emitting circuit.

[0026] The infrared emitting circuit described above also includes a first current-limiting resistor R1. The switching transistor is an NPN transistor. The current input terminal of the infrared emitting transistor is connected to the positive power supply through the first current-limiting resistor R1, the current output terminal is connected to the collector of the transistor, the base of the transistor is connected to the control interface, and the emitter is grounded.

[0027] The aforementioned sensing module includes an infrared receiver and a pull-up resistor R3. Its signal output terminal is connected to the gesture detection interface and also connected to the positive power supply via the pull-up resistor R3. The positive power supply terminal is connected to the positive power supply, forming an infrared receiving circuit. In this scheme, when no infrared signal is detected, the infrared receiving circuit maintains a high level through the pull-up resistor R3. When a valid infrared signal is detected, the output terminal of the receiver changes from high to low. The microcontroller MCU1 detects this level change to identify the signal and execute corresponding control.

[0028] The aforementioned infrared signal receiving circuit also includes a second current-limiting resistor R2, a first filter capacitor C1, and a power supply decoupling circuit. The middle pin of the infrared receiver is directly grounded, and its signal output pin is connected to the infrared detection interface of the microcontroller MCU1 via the second current-limiting resistor R2. It is also pulled up to the +5V power supply via a pull-up resistor R3 and grounded via a filter capacitor to filter out noise. The power supply pin of the infrared receiver is connected to the positive power supply via a third current-limiting resistor R4 and grounded with a decoupling capacitor for stable power supply. When the infrared signal is received by the infrared receiver, its internal demodulation circuit outputs a low-level pulse. This pulse is current-limited by the first current-limiting resistor R1 and filtered by the first filter capacitor C1 before being transmitted to the microcontroller MCU1. The microcontroller MCU1 detects the level change and sends a signal to the main control module.

[0029] The power supply decoupling circuit described above consists of a third current-limiting resistor R4 and a second filter capacitor C2.

[0030] The sensing electrode of the aforementioned electrode touch switch K1 is circular, with a diameter ranging from 10mm to 20mm.

[0031] In one embodiment, the microcontroller MCU1 includes a timing module and a storage module. The microcontroller MCU1 records the current state and current mode of the support frame 2 through the storage module. The microcontroller MCU1 records the trigger duration of the electrode touch switch K1 at regular intervals through the timing module. The microcontroller MCU1 has a working mode and a sleep mode. When the trigger duration reaches a preset duration t1, the sensing module switches modes.

[0032] When the sensing module enters sleep mode, the microcontroller MCU1 disconnects the infrared emitting circuit through the control interface.

[0033] In another embodiment, the operating modes include a hand-scanning mode, a touch mode, and a dual-coordination mode. Once the MCU enters an operating mode, it can switch between different modes. In specific applications, this can be achieved by connecting a microcontroller to a switch, or by switching between different operating modes over a preset duration t2.

[0034] Furthermore, the sensing module includes a power module, which is equipped with a wireless power receiving unit, an energy storage unit, and a power transmission unit. The main control module is equipped with a wireless power supply unit, which supplies power to the wireless power receiving unit of the power module through the wireless power supply unit. The energy storage unit is used to store electrical energy and supplies power to the microcontroller through the power transmission unit.

The main control chip is electrically connected to the sensing module and is connected to the power supply circuit of the drive motor through the steering control chip. The main control chip is also electrically connected to the steering control chip, so that the main control chip receives signals from the input sensing module and sends control signals to drive the power supply circuit of the steering control chip.

[0037] The aforementioned support frame 2 includes a fixed support 3 and a movable support 4. The fixed support 3 includes two longitudinally symmetrically arranged fixed arms 31. The movable support 4 includes a movable arm 41, which is movably connected to the fixed arm 31 and can move longitudinally relative to the fixed arm 31. The two ends of the basket 5 are connected to the movable arm 41, and the sensing unit 43 is connected between the two movable arms 41.

[0038] The aforementioned fixed support 3 includes a top beam 32, with its two sides connected to the upper ends of two fixed arms 31 to form a U-shaped structure. The lifting drive device includes a lifting drive mechanism and a lifting transmission mechanism. Both the lifting drive mechanism and the main control module are mounted on the top beam 32. The lifting drive mechanism is connected to the movable arm 41 through the lifting transmission mechanism. In this design, the top beam 32 is connected to the fixed arms 31 on both sides to form a U-shaped structure, which enhances the stability and load-bearing capacity of the fixed support 3. The lifting drive mechanism and the main control module are both mounted on the top beam 32, achieving integrated component design. This design not only saves space but also makes the structure of the suspended platform 1 more compact and aesthetically pleasing.

[0039] The aforementioned top beam 32 has a hollow structure to form an installation cavity. The lifting drive mechanism and the main control module are both assembled in the installation cavity. Clearance openings 34 are provided on both sides of the lower end of the top beam 32. The upper end of the fixed arm 31 is fixed to the installation cavity, and the other end extends downward through the clearance opening 34. The lifting transmission mechanism is connected to the movable arm 41 through the clearance opening 34. In this design, the hollow structure of the top beam 32 provides ample installation space for components such as the lifting drive mechanism and the main control module, and also serves to shield and protect these components.

[0040] This invention significantly improves the operational reliability of the suspended platform 1 in complex environments such as dampness and oiliness by integrating a dual-mode sensing system that combines infrared gesture sensing and capacitive touch control. During operation, the user can simultaneously trigger both infrared gesture sensing and touch sensing, avoiding accidental touches caused by wet hands or oil when only touch control is used. It also expands the sensing area, allowing for sensitive response without requiring precise, continuous touches. The microcontroller MCU1 processes infrared and capacitive signals through multi-port collaborative processing, achieving complementary optimization of rapid gesture control and precise touch operation. This solves the inconvenience of traditional thin electrode operation and overcomes the risk of failure in high-interference scenarios such as kitchens and bathrooms with a single touch control mode, making the lifting control both environmentally adaptable and easy to operate.
