Description

Technical Field

[0001] This utility model relates to the field of venetian blind technology, and in particular to a self-closing frame for a flexible venetian blind. Background Technology

[0002] In places like hospitals, the use of windows needs to take into account multiple requirements such as ventilation, privacy protection, and hygiene and safety. Flexible louvers have been widely used because they have advantages such as flexible adjustment of light and ventilation and protection of privacy.

[0003] Most blinds require manual operation to open and close. When medical staff are busy, they often forget to close the blinds, causing heat or cold to be lost from the ward or treatment room, resulting in energy waste and making it difficult to maintain a stable temperature and humidity environment.

[0004] At the same time, if the blinds are not closed in time, indoor privacy will be exposed, and dust, mosquitoes and other insects will easily enter the room, affecting the indoor hygiene. Utility Model Content

[0005] The purpose of this invention is to provide a self-closing frame for a flexible venetian blind to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] The self-closing frame of the flexible venetian blind includes a mounting frame, a venetian body, and a controller. The venetian body is disposed within the mounting frame, and the controller is connected to the self-closing structure of the venetian body and controls its operation.

[0008] As a preferred embodiment of this utility model, the mounting frame is provided with a mounting groove, and the louver body is rotatably connected to the mounting groove via a rotating rod, the rotating rod being provided with a gear body.

[0009] As a preferred embodiment of this utility model, the self-closing structure includes two rack bodies, each rack body has a connecting rod at its top, a fixing rod is provided at the connection of the two connecting rods, a lifting block is installed on the front of the fixing rod, an electric push rod is provided on the top of the lifting block, a mounting frame is provided at the connection of the electric push rod, and two limiting blocks are also provided on the mounting frame.

[0010] As a preferred embodiment of this utility model, the rack body meshes with the gear body, and the rack body is connected to the connecting rod of the louver body through a connecting rod.

[0011] As a preferred embodiment of this utility model, the electric push rod is controlled by the controller to move up and down, thereby driving the louver body to open or close.

[0012] As a preferred embodiment of this utility model, the mounting frame is provided with a connecting groove and a placement groove. The connecting groove is used to install the rotating rod, and the placement groove is used to accommodate the controller.

[0013] As a preferred embodiment of this utility model, the controller includes a main control module, a power supply module, a timing module, and a relay module. The main control module receives user operation signals and controls the timing module to start a timer or real-time clock. After the timing module reaches its time, it sends a feedback signal to the main control module. The main control module controls the power supply to the electric push rod through the relay module. The power supply module supplies power to each module and the electric push rod.

[0014] As a preferred embodiment of this utility model, user operation is achieved by pressing an external button. After the external button is pressed, the signal is transmitted to the main control module. The main control module controls the electric push rod to open the louver body and simultaneously starts the timer module. After the timer ends, the main control module controls the relay module to disconnect the power supply to the electric push rod, so that the louver body automatically closes.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-5 As shown, this utility model provides a self-closing frame for a flexible louver, including a mounting frame 1, a louver body 3, and a controller 8. The louver body 3 is disposed inside the mounting frame 1, and the controller 8 is connected to the self-closing structure of the louver body 3 and controls its operation.

[0025] The flexible venetian blind self-closing frame is designed to solve the problem of inconvenient manual operation of traditional venetian blinds. Its core consists of three main components: the mounting frame 1, which serves as the basic load-bearing structure, is made of high-strength aluminum alloy with an anti-corrosion surface treatment, making it suitable for humid environments such as hospital wards and treatment rooms; the venetian body 3, which is composed of multiple flexible PVC or lightweight metal blades, not only has good light-blocking and heat insulation performance, but also effectively reduces noise during opening and closing, avoiding interference with the medical environment; and the controller 8, which integrates an intelligent control module, interacts with the self-closing structure of the venetian body 3 through wired or wireless connection to achieve automated control. This design, through modular combination, can be quickly installed on existing window frames without large-scale modifications, adapting to the diverse decoration styles and spatial layouts of hospitals.

[0026] The mounting frame 1 is provided with a mounting groove 2, and the louver body 3 is rotatably connected to the mounting groove 2 through a rotating rod 4. The rotating rod 4 is provided with a gear body 41.

[0027] The mounting frame 1 has precision-machined mounting grooves 2 on both sides. The inner surface of the grooves is smoothed to reduce frictional wear between the rotating rod 4 and the groove wall, extending service life. The louver body 3 is embedded in the mounting grooves 2 through the rotating rods 4 at both ends, forming a stable rotating connection structure. This ensures that the louver remains stable during opening and closing, without shaking or shifting. The rotating rod 4 is made of stainless steel, which has high strength and corrosion resistance. Its outer surface has a high-precision machined gear body 41. The gear tooth shape is optimized to perfectly mesh with the subsequent rack structure, ensuring efficient and accurate power transmission. This design not only simplifies the installation process but also facilitates the disassembly and maintenance of the louver body 3 later, reducing the cost and difficulty of hospital equipment management.

[0028] The self-closing structure includes two rack bodies 51, each rack body 51 has a connecting rod 52 at its top, a fixing rod 53 at the connection of the two connecting rods 52, a lifting block 54 is installed on the front of the fixing rod 53, an electric push rod 57 is installed on the top of the lifting block 54, a mounting bracket 55 is installed at the connection of the electric push rod 57, and two limit blocks 56 are also provided on the mounting bracket 55.

[0029] The self-closing structure is the key component for the automatic opening and closing of the louvers. It consists of two symmetrically distributed rack bodies 51. The racks are made of high-strength plastic or metal with a wear-resistant surface treatment to ensure long-term durability. Each rack body 51 has a connecting rod 52 fixed to its top via a threaded connection or welding. The two connecting rods 52 converge at the top and are connected by a fixing rod 53 to form a stable rectangular frame structure. The lifting block 54 installed on the front of the fixing rod 53 enables lifting and lowering. The electric push rod 57 serves as the power source, using a low-noise, high-torque model. It is fixed to the top of the mounting frame 1 via a mounting bracket 55. The limit blocks 56 on both sides of the mounting bracket 55 are made of rubber. When the electric push rod 57 is raised or lowered to its limit position, the limit blocks 56 can effectively buffer the movement, prevent excessive impact, protect the electric push rod 57 and other components, and ensure the accuracy of the louver's opening and closing angle.

[0030] The rack body 51 meshes with the gear body 41, and the rack body 51 is connected to the connecting rod 52 of the louver body 3 through the connecting rod 52.

[0031] The rack body 51 and the gear body 41 on the rotating rod 4 form a precise meshing transmission structure. When the electric push rod 57 drives the lifting block 54 to move up and down, it drives the fixed rod 53 and the connecting rod 52 to move synchronously, thereby causing the rack body 51 to slide in the vertical direction. Due to the meshing of the rack and the gear, the linear motion of the rack is converted into the rotational motion of the gear, which drives the rotating rod 4 to rotate, realizing the opening and closing action of the louver body 3. The rack body 51 is connected to the connecting rod 52 of the louver body 3 by a hinge. This connection method not only ensures the effective transmission of power, but also allows the louver body 3 to freely adjust the angle within a certain range to meet different lighting and privacy protection needs. In addition, the hinge structure design makes the louver body 3 easier to install and disassemble, and the operation can be completed without complicated tools, improving maintenance efficiency.

[0032] The electric push rod 57 is controlled by the controller 8 to move up and down, thereby opening or closing the louver body 3.

[0033] The electric push rod 57 serves as the actuator for the automatic opening and closing of the louvers. Its operation is precisely controlled by the controller 8. The controller 8 controls the power supply to the electric push rod 57 through the internal relay module 84. When the user issues an opening command via an external button or a preset program, the main control module 81 of the controller 8 receives the signal and drives the relay module 84 to close the circuit. The electric push rod 57 is energized and begins to extend, driving the rack body 51 and the louver body 3 to move upward, thus opening the louvers. When the time set by the timer module 83 is reached or the user issues a closing command, the main control module 81 controls the relay module 84 to disconnect the circuit. The electric push rod 57 is de-energized and retracts under the action of the internal spring, driving the louver body 3 to move downward until it is completely closed. The electric push rod 57 has a built-in overload protection device. When it encounters excessive resistance (such as the louvers being stuck by foreign objects), the push rod automatically stops running and sends a fault signal to the controller 8 to prevent equipment damage and ensure safe use.

[0034] The mounting frame 1 is provided with a connecting groove 6 and a placement groove 7. The connecting groove 6 is used to install the rotating rod 4, and the placement groove 7 is used to accommodate the controller 8.

[0035] The mounting frame 1 is designed with full consideration of structural compactness and ease of installation. It is specially equipped with a connecting groove 6 and a placement groove 7. The connecting groove 6 is located in the middle of both sides of the mounting frame 1. The depth and width of the groove have been precisely calculated to tightly wrap the rotating rod 4, while providing smooth rotation space for the rotating rod 4, ensuring that it will not loosen or deviate during transmission.

[0036] The controller 8 includes a main control module 81, a power supply module 82, a timing module 83, and a relay module 84. The main control module 81 receives user operation signals and controls the timing module 83 to start a timer or real-time clock. When the timer reaches its set time, the timing module 83 sends a feedback signal to the main control module 81. The main control module 81 controls the power supply to the electric push rod 57 through the relay module 84. The power supply module 82 supplies power to all modules and the electric push rod 57.

[0037] The controller 8 adopts a modular design, integrating four core components: main control module 81, power supply module 82, timing module 83, and relay module 84. The main control module 81 uses a high-performance microprocessor with powerful data processing and logic judgment capabilities. It can quickly receive and process user operation signals from external buttons and feedback signals from the timing module 83. The power supply module 82 adopts an isolated switching power supply design with overvoltage, overcurrent, and short-circuit protection functions. It can convert the 220V AC power commonly used in hospitals into stable DC power required by each module to ensure stable system operation.

[0038] The timing module 83 supports two modes: the timer mode allows users to customize the time interval for the blinds to close automatically, while the real-time clock mode can automatically control the opening and closing of the blinds at specific times according to a preset schedule. When the timing module 83 finishes timing, it will immediately send a signal to the main control module 81. The main control module 81 then controls the power supply of the electric push rod 57 through the relay module 84 to realize the automatic closing of the blinds. The relay module 84 uses a highly reliable solid-state relay, which has the advantages of fast response speed and no contact wear, effectively extending the service life of the controller 8.

[0039] The electrical control coordination and signal transmission methods of the main control module 81, power supply module 82, timing module 83 and relay module 84 are all easily matched and purchased by those skilled in the art. The specific model adopted will not have an essential impact on the implementation of the technical solution. Therefore, there are no restrictions on their models, nor is there any need to restrict them.

[0040] User operation is achieved by pressing an external button. After the external button is pressed, the signal is transmitted to the main control module 81. The main control module 81 controls the electric push rod 57 to open the louver body 3 and starts the timer module 83 at the same time. After the timer ends, the main control module 81 controls the relay module 84 to disconnect the power supply of the electric push rod 57, so that the louver body 3 can be automatically closed.

[0041] To facilitate operation by medical staff, this utility model uses an external button as the human-machine interface. The button is waterproof and dustproof, with clear markings on its surface for easy identification and use in a hospital environment. When a medical staff member presses the external button, the micro switch inside the button is triggered, and the generated electrical signal is transmitted to the main control module 81 of the controller 8 through a shielded cable. After receiving the signal, the main control module 81 immediately controls the relay module 84 to close the circuit, starting the electric push rod 57 to move upward, driving the louver body 3 to gradually open. At the same time, the timer module 83 is activated to start timing. The timing duration of the timer module 83 can be adjusted by the user through the setting interface of the controller 8, with a minimum setting of a few minutes and a maximum setting of several hours to meet the needs of different scenarios. When the timer module 83 completes the timing, it will send a signal back to the main control module 81. The main control module 81 then controls the relay module 84 to disconnect the circuit, the electric push rod 57 stops running and retracts under the action of the internal spring, driving the louver body 3 to close automatically, realizing an intelligent and automated operation process, effectively solving the problems of energy waste and privacy exposure caused by human negligence in traditional louvers.

[0042] Workflow

[0043] The mounting frame 1 is fixed with the rotating rod 4 via the mounting groove 2, and the louver body 3 is rotatably connected to the mounting frame 1 via the rotating rod 4. At this time, the louver is in the closed state.

[0044] The controller 8 (including the main control module 81, power supply module 82, timing module 83, and relay module 84) is installed in the placement slot 7. The electric push rod 57 is in the retracted state, and the rack body 51 is engaged with the gear body 41 but is not under force.

[0045] Medical staff press the external button, and the button signal is transmitted to the main control module 81 via cable.

[0046] The main control module 81 controls the relay module 84 to close the circuit, and the electric push rod 57 begins to extend after being energized.

[0047] The electric push rod 57 pushes the lifting block 54 upward through the mounting bracket 55, which in turn drives the fixed rod 53 and the connecting rod 52 upward, thereby driving the rack body 51 to slide vertically upward.

[0048] The rack body 51 meshes with the gear body 41 to drive the rotating rod 4 to rotate, which in turn drives the louver body 3 to gradually open (blade angle adjustment).

[0049] At the same time, the main control module 81 starts the timing module 83 and begins the countdown (the duration is preset by the user).

[0050] When the timing module 83 finishes timing, it sends a signal back to the main control module 81.

[0051] The main control module 81 controls the relay module 84 to disconnect the circuit, the electric push rod 57 is de-energized and retracts under the action of the internal spring.

[0052] The electric push rod 57 retracts, pulling the lifting block 54 downward, which in turn drives the rack body 51 to slide vertically downward through the fixed rod 53 and the connecting rod 52.

[0053] The rack body 51 drives the gear body 41 and the rotating rod 4 to rotate in the opposite direction, so that the louver body 3 gradually closes to the initial position.

[0054] If the louver body 3 encounters obstruction during opening / closing (such as being stuck by a foreign object), the built-in overload protection device of the electric push rod 57 is triggered, automatically stopping operation and sending a fault signal back to the controller 8 to avoid damage to the equipment.

[0055] The limit block 56 (mounted on the mounting bracket 55) cushions the electric push rod when it reaches its limit position to prevent excessive impact.

[0056] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
