Description

Technical Field

[0001] The utility model relates to an electric drive system for a hollow built-in rolling shutter window, in particular to an electric drive system with an electronic limit function, which is controlled by a remote control and the limit position is set. Background Art

[0002] The hollow glass built-in sunshade product is the crystallization of traditional sunshade products and new technologies. It has the comprehensive functions of hollow glass and sunshade products, including: sunshading, heat preservation, sound insulation, lighting adjustment, fire prevention, cold resistance, privacy, space saving, easy cleaning, etc.

[0003] Traditional hollow built-in rolling shutter windows usually rely on manual operation to control the lifting and lowering of the rolling shutter. This method is not only inconvenient to operate, but also cannot achieve precise limit control. There are electric drive rolling shutter systems in the prior art, but most of them rely on simple button control, lacking intelligent and automatic control means, and the user experience is poor. Therefore, it is of great practical significance to design an electric drive structure with high intelligence, convenient operation, and capable of precisely controlling the rolling shutter limit.

[0004] In addition, for the existing built-in electric rolling shutter hollow glass windows, the lowest and highest points of the rolling shutter lifting are written into the control firmware at the factory. Once the motor control firmware is enclosed in the window body, it cannot be rewritten without disassembling the window body. Therefore, users cannot customize and modify according to their own habits during use. Moreover, when the manufacturer manufactures the window body, it is necessary to know in advance the size of the window body to be matched in order to write the corresponding motor limit program. If the worker takes the wrong one accidentally during assembly and once it is assembled and sealed, it is necessary to disassemble the window body to modify. This existing design scheme is not only very unfavorable to the efficient production of the factory, but also the later maintenance cost is very high.

[0005] The limit control of the existing rolling shutter system relies on mechanical switches or program algorithms, and has the following defects: the mechanical limit switch generates noise due to the vibration of gear meshing (such as the problem of the collision of the bevel gear shown in the attachment Figure 3 ); while the program algorithm relies on the calculation of the motor speed and lacks a hardware feedback mechanism (such as the problem of error accumulation caused by the absence of an encoder). Summary of the Utility Model

[0006] The purpose of the utility model is to provide an electric drive system for a hollow built-in rolling shutter window, which is controlled by a remote control and the limit position is set, overcomes the deficiencies in the prior art, realizes higher precision and reliability, and reduces noise.

[0007] To achieve the above purpose, the present invention provides an electric drive system for a hollow built-in rolling shutter window, which is characterized by including:

[0008] The drive motor is a DC motor with an encoder, which is used to drive the rolling shutter up and down and provide a feedback signal of the motor rotation.

[0009] The motor drive module is used to control the forward and reverse rotation and stop of the motor.

[0010] The control board is used to process the encoder signal, control the motor drive, and process the remote control signal.

[0011] The remote control receiving module is used to receive the remote control signal.

[0012] The reset limit button is connected to a digital input pin of the control board. By detecting the button press state, the control board can perform the corresponding limit reset operation.

[0013] The voltage conversion module is used to convert the 220V AC power supply into the working voltage required by the motor and the control system.

[0014] The DC-DC buck module is used to step down the voltage output by the voltage conversion module to the working voltage of the control board and other low-voltage components.

[0015] The reel direction changer is used to connect the horizontally arranged reel and the vertically arranged motor and reduce the vibration and noise during the transmission process.

[0016] The drive motor is connected to the reel at the top of the rolling shutter through the reel direction changer. The encoder of the drive motor is connected to the encoder input pin of the control board. The control board is connected to the motor drive module. The motor drive module is connected to the forward and reverse control pins of the motor. The remote control receiving module is connected to the input pin of the control board.

[0017] Furthermore, the control board controls the drive motor to stop and rotate forward and reverse by storing the data of the limit positions, ensuring that the rolling shutter does not exceed the set limit positions.

[0018] Furthermore, the reel direction changer includes a first bevel gear and a second bevel gear that mesh with each other. The first bevel gear and the second bevel gear are respectively connected to the rotating shaft of the drive motor and the reel of the rolling shutter through flexible couplings.

[0019] Furthermore, the flexible coupling includes a first flange, a second flange, and an elastic element. The two ends of the elastic element are respectively connected to the first flange and the second flange.

[0020] Furthermore, the voltage conversion module is an AC-DC voltage conversion module, and the DC-DC buck module is an LM2596 DC-DC buck module.

[0021] Furthermore, the motor with an encoder is an N20 DC motor.

[0022] Furthermore, the motor drive module adopts an L298N dual H-bridge motor drive module.

[0023] Furthermore, the remote control receiving module is an infrared remote control receiving module based on the NEC protocol.

[0024] Furthermore, the control board adopts an Arduino Uno or ESP32 development board.

[0025] The beneficial effects of the present utility model are as follows: By adopting the electric drive system in this technical solution, users can customize and reset the highest and lowest limit positions of the rolling curtain lifting during use, and the control of the rolling curtain lifting can achieve higher precision and reliability in actual control.

[0026] In addition, by adopting this flexible coupling as an elastic connecting member in this solution, the vibration transmission between the motor and the reel can be effectively reduced, thereby reducing the vibration noise generated during the operation of the motor and improving the operation stability of the system and the user experience.

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1:

[0034] As Figure 1As shown in the figure, this embodiment provides an electric drive system for a hollow built-in rolling shutter window, including a drive motor 1, a control board 2, a motor drive module 3, a remote control receiving module 4, a voltage conversion module 5, a DC-DC buck module 6, a reset limit button 7, and a reel direction changer 8.

[0035] The drive motor 1 is connected to the reel 9 of the rolling shutter through the reel direction changer 8. The encoder signal of the drive motor 1 is processed by the control board 2 to achieve precise position control of the rolling shutter. The motor drive module 3 controls the forward and reverse rotation and stop of the drive motor 1. The remote control receiving module 4 receives the remote control signal and transmits the rolling shutter lifting signal and limit setting signal sent by the remote control to the control board 2. The voltage conversion module 5 converts the 220V AC power supply into a 12V DC power supply for use by the drive motor 1 and the DC-DC buck module 6. The DC-DC buck module 6 steps down the 12V DC to 5V DC for use by the control board 2 and other low-voltage components. The reset limit button 7 is connected to a digital input pin of the control board 2. By detecting the button press state, the control board can perform corresponding limit reset operations.

[0036] The hardware components of this solution:

[0037] (1) Voltage conversion module: Use an AC-DC voltage conversion module, such as HLK-PM12, to convert 220V AC into 12V DC (suitable for 12V motors).

[0038] (2) DC-DC buck module: Use an LM2596 DC-DC buck module to step down 12V DC to 5V DC for supply to the control board and other low-voltage components.

[0039] (3) Drive motor: Use a model: N20 DC motor (with encoder, operating voltage is 12V).

[0040] (4) Control board: Use an Arduino Uno or ESP32 development board (operating voltage is 5V or 3.3V).

[0041] (5) Motor drive module: Use an L298N dual H-bridge motor drive module (operating voltage is 12V).

[0042] (6) Remote control receiving module: Use an infrared remote control receiving module (such as an infrared remote control receiving module with NEC protocol, operating voltage is 5V).

[0043] Control logic and program design

[0044] Control logic:

[0045] (1) Initialization

[0046] The control board initializes the encoder, the motor drive module, and the remote control receiving module.

[0047] Read the limit positions (such as the data stored in the EEPROM).

[0048] (2) Remote control

[0049] Control the rolling curtain to rise and fall through the remote control, and record the number of turns the motor rotates.

[0050] When reaching the required limit position, click the setting button to record the current number of turns as the limit position

[0051] (3) Limit control

[0052] According to the set limit positions, control the motor to stop and reverse to ensure that the rolling curtain does not exceed the set limit positions.

[0053] (4) Reset the limit

[0054] Click the button to reset the limit position, allowing a new limit position to be set again.

[0055] In this way, we have achieved controlling the rise and fall of the rolling curtain and setting the limits through the remote control, and converting the 220V AC power supply into the working voltage suitable for the motor and control system through the voltage conversion module 5 and the DC-DC buck module 6.

[0056] In addition, the implementation structure of the reel direction changer 8 is as Figure 3 shown, including a first bevel gear 81 and a second bevel gear 82 that mesh with each other. The first bevel gear 81 and the second bevel gear 82 are respectively connected to the rotating shaft of the drive motor 1 and the reel 9 of the rolling curtain through flexible couplings 83.

[0057] Among them, the specific structure of the flexible coupling 83 is as Figure 4 shown, including a first flange 831, a second flange 832, and an elastic element 833. The two ends of the elastic element 833 are respectively connected to the first flange 831 and the second flange 832.

[0058] Component description of the flexible coupling:

[0059] First flange and second flange:

[0060] Materials: aluminum alloy, stainless steel, or engineering plastics.

[0061] Functions: Fixed on the motor shaft and the reel respectively to transmit torque.

[0062] Elastic element:

[0063] Materials: rubber, polyurethane, or other high-elasticity materials.

[0064] Function: Connect the first flange and the second flange, absorb and buffer the vibrations generated by the motor movement, and reduce vibration transmission.

[0065] Installation steps:

[0066] First flange: Fix the first flange on the motor shaft and ensure its firm connection through screws or clamping devices.

[0067] Second flange: Fix the second flange on the reel and ensure its firm connection through screws or clamping devices.

[0068] Connect the elastic element: Connect the elastic element to the first flange and the second flange to ensure a firm connection.

[0069] Adjustment and calibration: (1) Ensure the central alignment of the coupling to avoid additional vibrations caused by eccentricity. (2) Adjust the tension of the elastic element to ensure that it can effectively absorb vibrations during operation.

[0070] Embodiment 2:

[0071] The difference between this embodiment and the above Embodiment 1 is that the drive motor is a DC motor with a working voltage of 24V, which is used to provide a more powerful driving force and is suitable for a larger area of window structure. The matching voltage conversion module needs to convert 220V AC to 24V DC. Then, through the DC-DC buck module, the 24V DC is bucked down to 5V DC to supply the control board and other low-voltage components.

[0072] It should be noted that in this article, terms such as "including", "comprising" or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. Without further limitations, an element defined by the statement "including a..." does not exclude the existence of additional identical elements in the process, method, article or device including the said element.

[0073] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
