Description

Technical Field

[0001] The present application relates to the field of sliding doors, and in particular to a wireless anti-pinch control method, device and equipment for sliding doors. Background Art

[0002] Sliding doors are widely used in residential, commercial, and public facilities due to their space-saving and convenient operation. Traditional sliding doors typically consist of a fixed frame and a movable leaf. The movable leaf, driven by a motor, moves along a track to open and close the door. However, if a user (especially children or pets) is accidentally trapped between the door leaf and the door frame during the closing process, this can easily cause injury, posing a significant safety hazard.

[0003] Currently, to prevent pinching injuries with sliding doors, a common solution is to install contact sensors (such as infrared sensors, pressure sensors, or capacitive sensors) on the door leaf or door frame. While these sensors can detect obstacles and trigger anti-pinch action, high-precision sensors, such as infrared beam sensors, are expensive, significantly increasing the manufacturing cost of sliding doors. They also require additional slots or sensor modules in the movable leaf, compromising the door's structural integrity. Because the sensor wiring moves with the movable leaf, long-term friction can easily lead to cable breakage or poor contact.

[0004] Therefore, it is necessary to provide a wireless anti-pinch control method, device and equipment for sliding doors that can avoid anti-pinch control failure caused by line friction damage. Summary of the Invention

[0037] The embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0038] It should be noted that when a component is considered to be "connected to" another component, it can be directly connected to the other component or there may be an intermediate component. When a component is considered to be "disposed on" another component, it can be directly disposed on the other component or there may be an intermediate component.

[0039] An embodiment of the present application provides a wireless anti-pinch control method for a sliding door. The sliding door includes a fixed frame formed with a slide rail and a movable fan that slides along the slide rail under the drive of a motor unit. When the movable fan slides in a first direction and the fan frame of the movable fan is touched by an external force, the method includes:

[0040] Touch the anti-pinch rubber strip on the fan frame, so that the disconnected strip-shaped pressure sensors set in the anti-pinch rubber strip come into contact with each other to form a conductive wire loop;

[0041] When the wire loop is connected, the wireless transmission module is triggered to start and generate and send a contact signal;

[0042] The wireless receiving module on the fixed frame receives the contact signal and converts the contact signal into a control signal;

[0043] According to the control signal, the driving control unit controls the movable fan to execute an anti-pinch instruction.

[0044] The above-mentioned wireless anti-pinch control method and device for sliding doors are designed so that when the movable fan slides along a first direction (such as the closing direction), if the fan frame of the movable fan is touched externally (for example, the user's hand, body or pet is clamped between the movable fan and the fixed frame), the touch force will be applied to the anti-pinch rubber strip. The anti-pinch rubber strip is squeezed and deformed, causing the originally disconnected bar-shaped pressure sensors to contact each other, thereby forming a conductive wire loop. The wireless transmitter module is thereby activated to send a signal to the wireless receiver module on the fixed frame, thereby controlling the movable fan to execute the anti-pinch instruction, such as stopping the sliding of the movable fan or making it slide in the opposite direction, thereby timely detecting the external touch of the movable fan during the closing process and quickly triggering the anti-pinch action, effectively avoiding the user (especially children or pets) being clamped between the door leaf and the door frame and causing the pinching accident, thereby greatly improving the safety of the sliding door. At the same time, the use of wireless communication avoids the friction problem caused by the line connection between the movable fan and the fixed frame, greatly reducing the risk of anti-pinch control failure due to line damage.

[0045] Below is a diagram of the Figures 1-4 , some embodiments of the present application are described in detail. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0046] An embodiment of the present application provides a wireless anti-pinch control method for a sliding door. The sliding door includes a fixed frame 10 formed with a slide rail and a movable fan 20 that slides along the slide rail under the drive of a motor unit 30. When the movable fan 20 slides in a first direction F1 and the fan frame 21 of the movable fan 20 is touched by an external force, the method includes:

[0047] S10 touches the anti-pinch strip 22 on the fan frame 21, so that the anti-pinch strip 22 is provided with disconnected strip pressure sensors in contact with each other to form a conductive wire loop;

[0048] S20. When the wire loop is turned on, the wireless transmitter module is triggered to start and generate and send a contact signal;

[0049] S30. The wireless receiving module on the fixed frame 10 receives the contact signal and converts the contact signal into a control signal;

[0050] S40. According to the control signal, the driving control unit controls the movable fan 20 to execute an anti-pinch instruction.

[0051] Specifically, in the embodiment of the present application, the first direction F1 is that the motor unit 30 controls the movable fan 20 to move in the door closing direction. The anti-pinch rubber strip 22 is in the shape of a long strip and is fixed to the fan frame 21 of the movable fan 20 by using strong glue on the outside of the anti-pinch rubber strip 22. The interior of the anti-pinch rubber strip 22 is hollow and is used to accommodate a strip-shaped pressure sensor. The rubber strip itself has a certain elasticity and can deform in the first time when squeezed by external force, so that the originally disconnected wires are in contact and conductive.

[0052] Furthermore, the strip pressure sensor includes a first conductor 221 and a second conductor 222, which are spaced apart and arranged opposite each other. The first conductor 221 and the second conductor 222, which are disconnected within the anti-pinch rubber strip 22, are normally disconnected, ensuring that no false signals are generated when no contact occurs. However, when the rubber strip is compressed and deformed, the two conductors contact each other to form a conductive wire loop, converting mechanical contact into an electrical signal, replacing traditional sensors and providing the basis for subsequent signal triggering.

[0053] The motor unit 30 can be a DC motor or a stepper motor, connected to the movable fan 20 via a transmission mechanism such as gears and chains to achieve sliding movement of the movable fan 20. The motor unit 30 is bolted to the fixed frame 10, with its output shaft connected to the transmission mechanism. Upon receiving control signals from the wireless receiver 50, the motor unit 30 controls the direction and speed of the motor, causing the movable fan 20 to execute the corresponding anti-pinch command.

[0054] The control unit transmits a control signal to the motor unit 30 , thereby driving the motor unit 30 to control the moving direction of the movable fan 20 . The control unit is a control panel or a controller.

[0055] The conduction of the wire loop provides a trigger condition for the wireless transmitter module. When the wire loop is conductive, it can provide the wireless transmitter module with operating voltage and / or transmission signals, thereby activating the wireless transmitter module. After activation, the wireless transmitter module generates and transmits a contact signal. Using the wireless transmitter module to send signals avoids the need for physical wiring between the movable fan 20 and the fixed frame 10. In traditional wired solutions, the wiring needs to move with the movable fan 20, and long-term friction can easily lead to cable breakage or poor contact.

[0056] The wireless receiving module is mounted on the fixed frame 10 and positioned opposite the wireless transmitting module on the movable fan 20. This ensures stable reception of contact signals from the wireless transmitting module, enabling signal transmission without physical connections. Upon receiving the contact signal, the wireless receiving module decodes and processes the signal, converting it into a control signal. The control unit recognizes the control signal and drives the motor unit 30 to control the movement of the movable fan 20.

[0057] The anti-pinch method of the present application is applicable to the case where a user or pet passes by the sliding door during the closing process of the movable fan 20 and touches the fan frame 21 of the movable fan 20 while passing by, triggering the anti-pinch action of the sliding door, thereby avoiding personal injury.

[0058] In a specific embodiment, the movable fan 20 is controlled to execute at least one of the following anti-pinch instructions:

[0059] Stop moving the movable fan 20;

[0060] The movable fan 20 is controlled to move along a second direction opposite to the first direction F1 .

[0061] Specifically, the anti-pinch instruction can be set according to actual needs, and commonly includes stopping the movable fan 20 or controlling the movable fan 20 to move in a second direction opposite to the first direction F1.

[0062] It should be noted that the first direction F1 is the closing direction of the movable fan 20 , and the second direction is the opening direction of the movable fan 20 .

[0063] After receiving the control signal, the drive control unit analyzes and determines the signal. Upon receiving the control signal, the control unit can execute a command to stop the movement of the movable fan 20 by cutting off the power supply to the motor unit 30, thereby stopping the movement of the movable fan 20. Alternatively, the control unit can control the movement of the movable fan 20 in the reverse direction by changing the direction of the motor unit 30, causing the movable fan 20 to move in a second direction opposite to the first direction F1. This prevents the movable fan 20 from exerting further pressure on the object or person touching it, thereby preventing further exacerbation of the pinching situation.

[0064] In a specific embodiment, when the wire loop is not conductive, the wireless sending module is in an inactive state.

[0065] Specifically, the wire loop serves as a key signal path for determining whether a touch event has occurred. Its continuity directly reflects whether the movable fan 20 and the fan frame 21 have been touched. When the wire loop is disconnected, it means the anti-pinch rubber strip 22 has not been squeezed or deformed, meaning no touch event has occurred. This status provides a basis for determining the operating status of the subsequent wireless transmission module.

[0066] The wireless transmitter module activates only when it needs to transmit a signal. When the wire loop is disconnected (i.e., when there is no contact), it remains inactive, avoiding unnecessary signal transmission and reducing signal interference. The module consumes virtually no power when inactive, significantly reducing the power consumption of the entire sliding door anti-pinch control system. This extends the life of the associated battery (if any), reduces reliance on external power sources, and lowers operating costs.

[0067] In a specific embodiment, one end of the first wire and one end of the second wire are connected to the wireless transmission module, and the conduction of the wire loop provides an operating voltage and / or transmits a signal to the wireless transmission module.

[0068] Specifically, one end of the first wire 221 is connected to the input terminal (such as the VCC pin) of the wireless transmitter module 40 by welding or plugging, and one end of the second wire 222 is connected to the input terminal of the wireless transmitter 40 or directly short-circuited to the power ground (GND), and the other end of the first wire 221 is spaced apart from the other end of the second wire 222. When the wire loop is conductive, current flows from the power end through the first wire 22, the VCC pin of the wireless transmitter module 40, the internal circuit of the wireless transmitter module, and the GND pin to the second wire 222, forming a complete power supply circuit, providing operating voltage for the wireless transmitter 40, enabling it to start and send a contact signal. For example, the power end can be a small DC power supply, such as a 5V DC power battery, to provide a stable operating voltage for the wireless transmitter module. When the anti-pinch rubber strip 22 is not touched, the other end of the first wire 221 is spaced apart from the other end of the second wire 222, the wire loop is disconnected, and the wireless transmitter 40 does not operate.

[0069] The first wire 221 is made of copper wire with good electrical conductivity. Its diameter is selected based on the actual current demand and installation space, and is generally 0.5-1 mm. One end of the first wire 221 is connected to the wireless transmitter module by welding or crimping to ensure a secure connection and low contact resistance. The second wire 222 is also made of copper wire and has the same diameter as the first wire 221. One end of the second wire 222 is connected to the wireless transmitter 40 by welding or crimping, and the other end extends into the hollow cavity 20a of the anti-pinch rubber strip 22, opposite the first wire 221.

[0070] A detection circuit device may be provided inside the wireless transmitter 40 , and the circuit may monitor the voltage or current at the input end in real time.

[0071] When a rising voltage edge is detected, the voltage detection circuit generates a trigger pulse and transmits this pulse signal to the signal processing module of the wireless transmitter 40. Upon receiving the trigger pulse, the signal processing module activates the wireless transmission module, generating and transmitting a specific wireless contact signal. Similarly, when the wire loop is conducting, the current detection circuit monitors the current in real time and compares it with a preset current threshold. If the current exceeds a certain threshold, the current detection circuit generates a corresponding signal and transmits it to the signal processing module. Based on the received signal, the signal processing module generates and transmits the corresponding wireless contact signal.

[0072] In one embodiment, the present application also provides a wireless anti-pinch control device 100 for a sliding door, which implements any of the above-mentioned wireless anti-pinch control methods for a sliding door. The control device comprises an anti-pinch rubber strip 22, a wireless receiver 50, a wireless transmitter 40, a wire loop, and a motor unit 30.

[0073] The anti-pinch rubber strip 22 is arranged on the sash 21 of the movable panel 20.

[0074] The wireless receiver 50 is arranged on the fixed frame 10.

[0075] The wireless transmitter 40 is arranged on the sash 21 of the movable panel 20 and is arranged opposite the wireless receiver 50.

[0076] The wire loop is arranged in the anti-pinch rubber strip 22 and is connected to the wireless transmitter 40.

[0077] The motor unit 30 is connected to the wireless receiver 50 to control the movement of the movable panel 20.

[0078] Specifically, it should be noted that the anti-pinch rubber strip 22 is tightly fitted on the edge of the sash 21 of the movable panel 20 that is close to the fixed frame 10. The length of the anti-pinch rubber strip 22 is consistent with the length of the edge of the sash 21 of the movable panel 20, ensuring that the entire edge can play a role in anti-pinch during the closing process of the movable panel 20. The anti-pinch rubber strip 22 is made of soft and elastic rubber material, such as silicone rubber or ethylene-propylene-diene rubber, so that it can deform significantly when subjected to pressure. The inside of the anti-pinch rubber strip 22 is a hollow cavity 20a structure, which provides space for the arrangement of the wire loop. The cross-sectional shape of the rubber strip is designed as a flat D” shape. The sash 21 and the fixed frame 10 are arranged opposite each other. When the movable panel 20 moves the sash 21 towards the fixed frame 10, the wireless transmitter 40 on the movable panel 20 also moves towards the wireless receiver 50 on the fixed frame 10,

[0079] The motor unit 30 is installed at the bottom or top of the fixed frame 10 and is connected to the movable panel 20 through a transmission mechanism (such as a gear, chain, or belt).

[0080] When the movable panel 20 is in the opening or normal closing process, the anti-pinch rubber strip 22 is not touched, the first wire 221 and the second wire 222 are in a spaced state, and the wire loop is disconnected. The wireless transmitter 40 does not work, and the motor unit 30 normally drives the movable panel 20 to move along the track of the fixed frame 10.

[0081] When the activity fan 20 is in the closing process, if there is an object touching the anti-pinch rubber strip 22, the anti-pinch rubber strip 22 is deformed, the first wire 221 and the second wire 222 are in contact with each other, and the wire loop is conducted. The wireless transmitter 40 moves with the activity fan 20, and when it receives the signal of the wire loop conduction, it triggers the signal transmission module to send a wireless signal to the wireless receiver 50 installed on the fixed frame 10. After the wireless receiver 50 receives the wireless signal, it decodes the signal and controls the signal output module to output a control signal to the motor unit 30. The motor unit 30 is installed on the fixed frame 10, and the motor controller controls the motor to stop rotating or reverse according to the control signal, so that the activity fan 20 stops closing or reverses opening, thereby avoiding the occurrence of pinching accidents.

[0082] In one embodiment, the anti-pinch rubber strip 22 is provided with a hollow cavity 20a, and the wire loop is arranged in the hollow cavity 20a;

[0083] The wire loop comprises:

[0084] The first wire 221 is arranged in the hollow cavity 20a;

[0085] The second wire 222 is arranged in the hollow cavity 20a opposite to the first wire 221.

[0086] Specifically, the cross-sectional shape of the hollow cavity 20a in the anti-pinch rubber strip 22 is designed as a flat D-shaped shape, the flat side of which is fixed on the fan frame 21 of the activity fan 20 by strong glue or the like, and the side with curvature faces outward, and the first wire 221 and the second wire 222 in the rubber strip can be fixed in the rubber strip by strong glue or the like. In order to ensure that the wire does not shift during the deformation of the rubber strip, the strong glue is uniformly applied to the contact surface between the wire and the inner wall of the rubber strip, and the wire is arranged in a straight line in the rubber strip, and the two wires are arranged opposite to each other with a spacing of about 2-3 mm.

[0087] When the activity fan 20 is in the closing process, if there is an object touching the anti-pinch rubber strip 22, the rubber strip is deformed by extrusion, the space in the hollow cavity 20a is compressed, and the originally spaced first wire 221 and the second wire 222 are in contact with each other, and the wire loop is conducted.

[0088] In one embodiment, one end of the first wire 221 and the second wire 222 is connected with the wireless transmitter 40, and the other end of the first wire 221 and the other end of the second wire 222 are arranged with a spacing.

[0089] Specifically, one end of a wire 221 is connected to the input terminal (such as the VCC pin) of the wireless transmitter module 40 by welding or plugging, and one end of a second wire 222 is connected to the input terminal of the wireless transmitter 40 or is directly short-circuited to the power ground (GND), and the other end of the first wire 221 is spaced apart from the other end of the second wire 222. When the wire loop is conductive, current flows from the power end through the first wire 22, the VCC pin of the wireless transmitter module 40, the internal circuit of the wireless transmitter module, and the GND pin to the second wire 222, forming a complete power supply circuit, providing operating voltage for the wireless transmitter 40, enabling it to start and send a contact signal. For example, the power end can be a small DC power supply, such as a 5V DC power battery, to provide a stable operating voltage for the wireless transmitter module. When the anti-pinch rubber strip 22 is not touched, the other end of the first wire 221 is spaced apart from the other end of the second wire 222, the wire loop is disconnected, and the wireless transmitter 40 does not operate.

[0090] In one embodiment, a computer-readable storage medium is provided, storing a computer program. When the computer program is executed by a processor, the processor is caused to perform the steps of any one of the methods.

[0091] Those skilled in the art will appreciate that all or part of the processes in the above-mentioned embodiments can be implemented by instructing the relevant hardware through a computer program. The program can be stored in a non-volatile computer-readable storage medium. When the program is executed, it can include the processes of the embodiments of the above-mentioned methods. Among them, any reference to memory, storage, database or other media used in the embodiments provided in this application can include non-volatile and / or volatile memory. Non-volatile memory can include read-only memory (ROM), programmable ROM (PROM), electrically programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM) or flash memory. Volatile memory can include random access memory (RAM) or external cache memory. By way of illustration and not limitation, RAM is available in various forms, such as static RAM (SRAM), dynamic RAM (DRAM), synchronous DRAM (SDRAM), double data rate SDRAM (DDRSDRAM), enhanced SDRAM (ESDRAM), synchronous link (Synchlink) DRAM (SLDRAM), memory bus (Rambus) direct RAM (RDRAM), direct memory bus dynamic RAM (DRDRAM), and memory bus dynamic RAM (RDRAM).

[0092] In one embodiment, a computer device is provided, comprising a memory and a processor, wherein the memory stores a computer program, and when the computer program is executed by the processor, the processor is caused to perform the steps of any one of the methods.

[0093] Methods include:

[0094] S10 touches the anti-pinch strip 22 on the fan frame 21, so that the anti-pinch strip 22 is provided with disconnected strip pressure sensors in contact with each other to form a conductive wire loop;

[0095] S20. When the wire loop is turned on, the wireless transmitter module is triggered to start and generate and send a contact signal;

[0096] S30. The wireless receiving module on the fixed frame 10 receives the contact signal and converts the contact signal into a control signal;

[0097] S40. According to the control signal, the driving control unit controls the movable fan 20 to execute an anti-pinch instruction.

[0098] The computer device can be a terminal or a server. It includes a processor, memory, and a network interface connected via a system bus. The memory includes a non-volatile storage medium and internal memory. The non-volatile storage medium of the computer device stores an operating system and may also store a computer program. When executed by the processor, the computer program enables the processor to implement a wireless anti-pinch control method for sliding doors. The internal memory may also store a computer program. When executed by the processor, the computer program enables the processor to implement a wireless anti-pinch control method for sliding doors.

[0099] Thus, the wireless anti-pinch control method and device for sliding doors provided above is designed to prevent external contact when the movable fan 20 slides along a first direction F1 (e.g., the closing direction). If the fan frame 21 of the movable fan 20 is touched externally (e.g., a user's hand, body, or pet is trapped between the movable fan 20 and the fixed frame 10), the contact force is applied to the anti-pinch rubber strip 22. The anti-pinch rubber strip 22 is squeezed and deformed, causing the originally disconnected first and second wires 221 and 222 to contact each other, thereby forming a conductive wire loop. This activates the wireless transmitter module to send a signal to the wireless receiver module on the fixed frame 10, thereby controlling the movable fan 20 to execute anti-pinch instructions, such as stopping the sliding of the movable fan 20 or causing it to slide in the opposite direction. This timely detects external contact with the movable fan 20 during the closing process and quickly triggers the anti-pinch action, effectively preventing users (especially children or pets) from being trapped between the door leaf and the door frame and causing injuries, thereby greatly improving the safety of sliding door use. At the same time, the use of wireless communication avoids the friction problem caused by the line connection between the movable fan 20 and the fixed frame 10, and greatly reduces the risk of anti-pinch control failure caused by line damage.

[0100] The above is only an implementation method of the present application. It should be pointed out that for ordinary technicians in this field, improvements can be made without departing from the creative concept of the present application, but these all fall within the scope of protection of the present application.
