[0042] The following will clearly and completely describe the concept of the present application and the technical effects produced in combination with the embodiments, so as to fully understand the purpose, features and effects of the present application.

[0045] In the related art, the dimming glass installed on the glass door can switch the display state of the dimming glass according to the door opening and closing state, for example, it displays the fogging state in the closed state and the transparent state in the open state. In the related art, when the pivot door with the inside and outside opening function is closed vigorously, the door leaf easily passes the middle closing position to the other side, and when the door leaf passes the middle closing position, it will flicker, that is, the display state changes back and forth, or when the door is closed vigorously, it will vibrate back and forth at the closed position and flicker. In some technologies, the detection device is interfered with, which makes it difficult to detect the position accurately and easily causes flicker. For example, the electric sliding door has a large number of magnets arranged on its moving rails, which causes great interference (enhanced at specific positions, weakened at specific positions) to the sensing components (reed switches) set at both ends to sense whether the door leaf is open or closed. As a result, during the movement of the door leaf, it is sensed in advance at some distance (for example, about 20 mm) before reaching the tail end (door closing position), but not at a smaller distance (for example, about 10 mm) from the tail end. It is sensed again when it reaches the tail end, causing the glass to flicker. This not only affects the user experience, but also the service life of the dimming glass.

[0046] The embodiment of the present application provides a display module control device, a door body having the display module control device, and a display module control method. In the display module control device, the detection device 110 detects the first position of the connector 200, the switch device 300 connects the circuit of the display module, the delay module sends a switch signal according to the detection signal delay, and the relay switches the closed state or the conducting state according to the switch signal, thereby controlling the on and off of the display module and the power supply, realizing the control of the display state, effectively avoiding the influence of the display module position vibration or inaccurate position detection on the power-on state, thereby effectively solving the stroboscopic problem of the display module. The display module control device of the embodiment of the present application can be applied to various doors and windows provided with display modules, which is conducive to improving the user experience.

[0047] Among them, the display module can be a module such as dimming glass, LED lamp, etc. that can change the display state by powering on and off. For example, the display module can be dimming glass, which is transparent when powered on and atomized when powered off. Alternatively, the display module can be an LED lamp, which is luminous when powered on and non-luminous when powered off. The following is an introduction to the embodiments of the present application in conjunction with the drawings of the specification, which are illustrated by taking the display module using dimming glass as an example.

[0048] refer to Figures 1 to 4 The display module control device of the embodiment of the present application includes a positioning member 100, a connecting member 200, a switch device 300, a detection device 110, a delay module and a relay.

[0049] The connecting member 200 is suitable for connecting to the first display module 500 . The first display module 500 is configured to present different display states in the power-on state and the power-off state respectively. The connecting member 200 is used to drive the first display module 500 to move relative to the positioning member 100 .

[0050] The switch device 300 is electrically connected to the first display module 500 , and the switch device 300 is configured to connect the circuit of the display module when the connecting member 200 is located at the first position.

[0051] The detection device 110 is connected to the positioning member 100 and is used to detect whether the connecting member 200 is in the first position and send a detection signal. The connecting member 200 is used to connect the first display module 500, thereby reflecting the position of the first display module 500 and realizing the position detection of the first display module 500.

[0052] The relay is used to connect the first display module 500 and the power supply. The relay has a closed state and an open state. The relay is used to connect the first display module 500 and the power supply in the closed state, and is used to disconnect the first display module 500 and the power supply in the open state. The delay module is configured to send a switch signal with a delay according to the detection signal, and the relay is configured to switch the closed state or the open state according to the switch signal. Therefore, the relay can control the on and off of the first display module 500 and the power supply after the set delay time.

[0053] Thus, even if the connecting member 200 vibrates when it is at the first position, the vibration of the connecting member 200 can be eliminated or weakened after the set delay period, or, even if the detection device 110 sends a detection signal before the connecting member 200 reaches the first position, the connecting member 200 can actually reach the first position after the set delay period.

[0054] Therefore, after the set delay time, the relay controls the on / off of the first display module 500 and the power supply to change the display state of the first display module 500, which can effectively solve the flicker problem caused by repeated vibration or inaccurate detection of the first display module 500. Therefore, the number of on / off times of the first display module 500 and the relay can be reduced, thereby reducing unnecessary losses and effectively increasing the life of components.

[0055] The display module control device of the embodiment of the present application can be applied to doors and windows. The connecting piece 200 can be connected to the movable first display module 500 of the doors and windows, and the positioning piece 100 can be connected to the fixed structure such as the door frame and the window frame. Therefore, when the doors and windows are opened or closed, the position of the connecting piece 200 can be detected by the detection device 110 to detect the position of the first display module 500. The delay module can send a switching signal according to the delay of the detection signal. The relay can control the connection and disconnection of the first display module 500 and the power supply after the set delay period, thereby effectively solving the problem of display module flickering when the doors and windows are opened and closed.

[0056] In some embodiments, the delay module may include an MCU main control chip and a preset control program, and the control program presets the delay time length of the delay signal. The delay time length of the delay module can be 500ms to 1s, and can be 500ms, 600ms, 700ms, 800ms, 900ms, 1s or any other value between 500ms and 1s. The above-mentioned delay time length is sufficient for the first display module 500 to reduce or eliminate vibration, and is sufficient for the first display module 500 that has not reached the target position when the detection signal is sent to continue to move to the target position to achieve position stability, so that the connector 200 can be stabilized in the first position, and at this time, the relay controls the power on and off to realize the change of the state of the first display module 500, effectively avoiding the stroboscopic problem caused by repeated changes in the display state of the first display module 500.

[0057] refer to Figure 2 and Figure 4 In some embodiments, the display module control device further includes a first magnetic member 210 and a second magnetic member 120. The first magnetic member 210 is connected to the connecting member 200, and the second magnetic member 120 is connected to the positioning member 100. When the connecting member 200 is located at the first position, the second magnetic member 120 is magnetically connected to the first magnetic member 210, so that the relative position of the connecting member 200 and the positioning member 100 can be kept stable, thereby ensuring that the switch device 300 is stably connected.

[0058] refer to Figure 2 and Figure 4In some embodiments, the switch device 300 includes a fixed member 310 and a movable member 320 electrically connected to the first display module 500, respectively. The movable member 320 is connected to the connecting member 200, and the fixed member 310 is connected to the positioning member 100. When the connecting member 200 is located at the first position, the movable member 320 abuts against the fixed member 310 to connect the circuit of the first display module 500. Further, under the effect of the magnetic connection between the second magnetic member 120 and the first magnetic member 210, the relative position of the connecting member 200 and the positioning member 100 remains stable, thereby ensuring that the movable member 320 abuts against the fixed member 310 and is stably connected, and ensuring the stability of the electrical connection of the first display module 500.

[0059] Among them, one of the fixed part 310 and the movable part 320 can be a powered contact, and the other can be an elastic part made of conductive material, such as a conductive spring connected to a circuit through a wire. Therefore, under the action of the magnetic connection between the second magnetic member 120 and the first magnetic member 210, the elastic member and the powered contact are in contact and conductive, and the elastic member can be partially compressed, thereby exerting a certain elastic force on the powered contact, achieving elastic abutment, and partially buffering the vibration, effectively avoiding the problem of disconnection caused by small vibrations, and improving the stability of the connection.

[0060] In some embodiments, the first magnetic member 210 is a magnetic structure, and the detection device 110 is a reed switch, which is used to sense the first magnetic member 210 to detect whether the connector 200 is in the first position. The reed switch has the characteristics of simple structure and long service life. When the connector 200 drives the first magnetic member 210 to move close to the reed switch, and the reed switch senses a sufficiently strong magnetic field, the attraction between the reeds will overcome the external air pressure to adsorb them together, and the reed switch is in a closed state to form a passage, and the detection signal emitted is "1" or a high level; when the connector 200 drives the first magnetic member 210 to move away from the reed switch, the magnetic field disappears or weakens, the attraction between the reeds disappears, the reed switch is in a disconnected state, thereby disconnecting the passage, and the detection signal emitted is "0" or a low level.

[0061] In some related technologies, the movable glass of the electric sliding door adopts dimming glass. The two ends of the movable glass (door opening position and door closing position) are used for power supply. The movable glass is driven by a moving rail assembly. A large number of magnets are arranged on the moving rail assembly, which causes great interference to the sensing components (such as reed switches) set at both ends for sensing whether the movable glass is opened or closed. The interference is related to the magnetic field distribution. The moving rail assembly is a structure in which the moving rail magnets are arranged according to the ABAB rule directly above. The moving rail magnets are commonly used for magnetic levitation linear motors to drive the movable glass to move. Because the magnetic field of the moving rail magnets on the moving rail assembly will interact with the magnetic field of the target magnetic pole sensed by the sensing element (such as the first magnetic attraction member 210 of the embodiment of the present application), when the magnetic poles of the two magnets are directed to attract each other, the overall magnetic field strength will be enhanced; when the magnetic poles of the two magnets are directed to repel each other, the overall magnetic field strength will be weakened. Due to the interference of a large number of magnets on the moving rail assembly, some areas will cause the magnetic field to be strengthened, causing the sensing element to trigger the induction output induction signal in these areas, and some areas will cause the magnetic field to be weakened (for example, reference Figure 5 Area C in the middle), causing the sensing element to be unable to sense in these areas. Therefore, the movable glass is sensed and outputs a sensing signal at a certain distance (about 20mm) from the target position (door opening position or door closing position). The movable glass continues to move to a certain distance (about 10mm) from the tail end and is no longer sensed, thus disconnecting. When it moves to the target position again and contacts, it is sensed and outputs a sensing signal again, causing the flickering phenomenon of the movable glass. In some other solutions, in order to avoid the interference of the moving rail magnet, it is necessary to manually distinguish the polarity of the magnet for arrangement when installing the moving rail assembly. Because the N pole and S pole of the magnet cannot be directly distinguished by the naked eye, the installation is very inconvenient. Some embodiments of the present application can effectively solve the above problems.

[0062] refer to Figures 1 to 4 In some embodiments of the present application, the display module control device also includes a driving component 400, which is fixedly connected to the connecting member 200 and is used to drive the movable member 320 and the first display module 500 to move relative to the positioning member 100; the switch device 300 includes a fixed member 310 and a movable member 320 respectively electrically connected to the first display module 500, the movable member 320 is connected to the connecting member 200, and the fixed member 310 is connected to the positioning member 100. When the connecting member 200 is located in the first position, the movable member 320 abuts against the fixed member 310 to connect the circuit of the display module.

[0063] The driving component 400 of the embodiment of the present application can adopt a moving rail component. Under the magnetic field interference of the moving rail component, even if the detection device 110 detects the first magnetic attraction component 210 on the connecting member 200 in advance before the connecting member 200 reaches the first position and sends a detection signal, the relay will not immediately turn on the circuit of the first display module 500, but will send a switching signal through the delay module according to the detection signal delay, and the relay controls the closed state or the open state according to the switch signal. Therefore, after the set delay period, the first display module 500 can reach the target position, and the connecting member 200 can actually reach the first position and be detected by the detection device 110, and the repeated interruption of detection will not cause the change of the power-on state of the display module, thereby effectively solving the flicker problem.

[0064] Therefore, the magnetic field interference of the moving rail assembly will not affect the first display module 500 of the embodiment of the present application. Therefore, during installation, there is no need for magnets to distinguish the N / S polarity, which can facilitate production and installation.

[0065] refer to Figures 1 to 4 In some embodiments, the connecting member 200 and the positioning member 100 are arranged along a first direction, and the driving assembly 400 is a linear motion mechanism for driving the connecting member 200 to move along the first direction; the movable member 320 is arranged at one end of the connecting member 200 facing the positioning member 100, and the fixed member 310 is arranged at one end of the positioning member 100 facing the connecting member 200, thereby enabling the connection between the fixed member 310 and the movable member 320 to be achieved by moving the first display module 500 along the first direction.

[0066] Furthermore, the first magnetic member 210 is arranged at one end of the connecting member 200 facing the connecting member 200, and the second magnetic member 120 and the sensing device are arranged at one end of the positioning member 100 facing the connecting member 200, so that the magnetic attraction of the first magnetic member 210 and the second magnetic member 120 and the sensing device on the first magnetic member 210 can be achieved by moving the first display module 500 along the first direction.

[0067] The embodiment of the present application further provides a door body, including a door frame, a first display module 500 and a display module control device.

[0068] The first display module 500 is movably connected to the door frame, and can move relative to the door frame to a closed state or an open state.

[0069] The display module control device includes a positioning member 100, a connecting member 200, a switch device 300, a detection device 110, a delay module and a relay. The positioning member 100 is fixedly connected to the door frame, and the connecting member 200 is suitable for connecting to the first display module 500, and the connecting member 200 is used to drive the first display module 500 to move relative to the positioning member 100.

[0070] The switch device 300 is electrically connected to the first display module 500 , and the switch device 300 is configured to connect the circuit of the display module when the connecting member 200 is located at the first position.

[0071] The detection device 110 is connected to the positioning member 100, and is used to detect whether the connecting member 200 is in the first position and send a detection signal. The connecting member 200 is used to connect the first display module 500, thereby reflecting the position of the first display module 500 and realizing the position detection of the first display module 500. For example, when the connecting member 200 is in the first position, the first display module 500 is in a closed state, or, when the connecting member 200 is in the first position, the first display module 500 is in an open state.

[0072] The relay is used to connect the first display module 500 and the power supply. The relay has a closed state and an open state. The relay is used to connect the first display module 500 and the power supply in the closed state, and is used to disconnect the first display module 500 and the power supply in the open state. The delay module is configured to send a switch signal with a delay according to the detection signal, and the relay is configured to switch the closed state or the open state according to the switch signal. Therefore, the relay can control the on and off of the first display module 500 and the power supply after the set delay time.

[0073] refer to Figure 1 , Figure 3 and Figure 6 In some embodiments of the door body, the following display module control method can be used:

[0074] When the first display module 500 moves to the closed state, the detection device 110 detects that the connecting member 200 is in the first position and sends out a first detection signal. The delay module sends out a first switching signal with a delay according to the first detection signal. The relay forms a closed state in response to the first switching signal, thereby connecting the first display module 500 and the power supply.

[0075] The method can be applied to a sliding door structure, that is, the first display module 500 is movably connected to the door frame along a first direction, and moves relative to the positioning member 100 and the detection device 110 to realize the structure of opening and closing the door. When the sliding door is closed, the connecting member 200 and the first display module 500 move along the first direction close to the detection device 110 on the positioning member 100, and the detection device 110 detects that the connecting member 200 is in the first position and sends a first detection signal. The delay module sends a first switch signal with a delay according to the first detection signal, and the relay forms a closed state in response to the first switch signal, and the first display module 500 is connected to the power supply.

[0076] refer to Figure 7 In some other embodiments of the door body, the following display module control method can also be used for control:

[0077] When the first display module 500 moves to the closed state, the detection device 110 detects that the connecting member 200 is in the first position and sends a first detection signal, the delay module sends a first switch signal with a delay according to the first detection signal, and the relay forms a closed state in response to the first switch signal, and the first display module 500 is connected to the power supply. In addition, the detection device 110 does not detect that the connecting member 200 is in the first position (the connecting member 200 leaves the first position) and sends a second detection signal, the delay module sends a second switch signal with a delay according to the second detection signal, and the relay forms a closed state in response to the second switch signal, and the first display module 500 is connected to the power supply.

[0078] The method can be applied to a hinge door structure, that is, a structure in which the first display module 500 is connected to the door frame through a hinge, rotates around the hinge, and moves relative to the positioning member 100 and the detection device 110. When the hinge door is closed, the connecting member 200 and the first display module 500 rotate around the hinge to approach the detection device 110 on the positioning member 100, and the detection device 110 detects that the connecting member 200 is in the first position and sends a first detection signal, and the delay module sends a first switch signal with a delay according to the first detection signal, and the relay forms a closed state in response to the first switch signal, and the first display module 500 is connected to the power supply. In addition, the detection device 110 does not detect that the connecting member 200 is in the first position (the connecting member 200 leaves the first position and is far away from the detection device 110) and sends a second detection signal, and the delay module sends a second switch signal with a delay according to the second detection signal, and the relay forms a closed state in response to the second switch signal, and the first display module 500 is connected to the power supply.

[0079] Therefore, even after the door is closed, the vibration of the first display module 500 drives the connecting member 200 to vibrate when it is in the first position. After the set delay time, the vibration of the display module is eliminated or weakened, thereby eliminating or weakening the vibration of the connecting member 200, thereby ensuring the position stability of the fixed member 310 and the movable member 320 in the switch device 300. Therefore, the relay controls the on and off of the first display module 500 and the power supply after the set delay time to change the display state of the first display module 500, which can effectively solve the flickering problem caused by repeated vibration of the display module in the closed state.

[0080] Alternatively, even if the detection device 110 is disturbed, a detection signal is sent out or detection is interrupted before the connecting member 200 reaches the first position, and the first display module 500 does not actually reach the target state (door open state or door closed state), after the set delay time, the first display module 500 can move to the target state, so that the connecting member 200 can actually reach the first position, ensuring the position stability of the fixed member 310 and the movable member 320 in the switch device 300. Therefore, the relay controls the on-off of the first display module 500 and the power supply after the set delay time to change the display state of the first display module 500, which can effectively solve the flicker problem caused by repeated vibration or inaccurate detection of the display module.

[0081] The first display module 500 is configured to present different display states in the power-on state and the power-off state, for example, the first display module 500 is a dimming glass, which presents a transparent state in the power-on state and an atomized state in the power-off state. Alternatively, the first display module 500 is an LED lamp, which presents a light-emitting state in the power-on state and a non-light-emitting state in the power-off state. The delay module sends a switch signal according to the detection signal delay, and the relay can control the on and off of the first display module 500 and the power supply after the set delay time, thereby changing the display state of the first display module 500.

[0082] In the related art, some solutions of sliding doors include movable glass and fixed glass, both of which are dimming glass, and power is supplied to both ends of the movable glass (door opening position and door closing position), and the fixed glass is always connected to the wire. When the movable glass is a short distance before reaching the door opening position, the induction switch senses the movable glass in advance, and the movable glass and the fixed glass are powered on at this time, and the display state of the fixed glass becomes transparent, but the movable glass has not reached the door opening position at this time, and has not been powered on, the movable glass is still in the power-off state, and the display state is atomized, so the problem of different states of the movable glass and the fixed glass occurs at this time. Some embodiments of the present application effectively solve this problem.

[0083] In some embodiments of the present application, the door body includes the above-mentioned door frame, the first display module 500 and the display module control device, and also includes a second display module. The second display module is configured to present different display states in the power-on state and the power-off state, for example, the second display module is a dimming glass, which presents a transparent state in the power-on state and an atomized state in the power-off state. Alternatively, the second display module is an LED lamp, which presents a light-emitting state in the power-on state and a non-light-emitting state in the power-off state.

[0084] The second display module and the first display module 500 are arranged along the first direction, the second display module is fixedly connected to the door frame, and the positioning member 100 is connected to the second display module.

[0085] The first display module 500 is movably connected to the door frame along a first direction. Along the first direction, the first display module 500 can move relative to the second display module to a closed state or an open state.

[0086] The relay is used to connect the first display module 500, the second display module and the power supply. The relay is used to connect the power supply to the first display module 500 and the second display module in a closed state, and to disconnect the power supply to the first display module 500 and the second display module in an open state.

[0087] refer to Figure 6 , the door body of some embodiments of the present application can be controlled by the following display module control method:

[0088] When the first display module 500 moves to a closed state, the detection device 110 detects that the connecting member 200 is in the first position and sends out a first detection signal. The delay module sends out a first switch signal with a delay according to the first detection signal. The relay forms a closed state in response to the first switch signal, and the power supply is connected to the first display module 500 and the second display module; or, when the first display module 500 moves to an open state, the detection device 110 does not detect that the connecting member 200 is in the first position and sends out a second detection signal. The delay module sends out a second switch signal with a delay according to the second detection signal. The relay forms an open state in response to the second switch signal, and the power supply is disconnected from the first display module 500 and the second display module.

[0089] Alternatively, refer to Figure 7 , the door body of some embodiments of the present application can also be controlled by the following display module control method:

[0090] When the first display module 500 moves to a closed state, the connecting member 200 moves close to the detection device 110, and the detection device 110 detects that the connecting member 200 is in the first position and sends out a first detection signal. The delay module sends out a first switch signal with a delay according to the first detection signal, and the relay forms a closed state in response to the first switch signal, and the power supply is connected to the first display module 500 and the second display module; and, the detection device 110 does not detect that the connecting member 200 is in the first position (the connecting member 200 moves away from the detection device 110, or the detection device 110 is interfered and cannot be sensed) and sends out a second detection signal, the delay module sends out a second switch signal with a delay according to the second detection signal, and the relay forms a closed state in response to the second switch signal, and the power supply is connected to the first display module 500 and the second display module.

[0091] Thus, the detection device 110 is connected through the positioning member 100, the connecting member 200 is connected to the first display module 500, the detection device 110 detects the position of the connecting member 200, and realizes the detection of the position of the first display module 500. The delay module sends a switch signal according to the detection signal delay, and the relay can control the connection and disconnection of the first display module 500 and the power supply after the set delay time. Therefore, even if the first display module 500 reciprocates in the closed state, or the detection device 110 is disturbed, and sends a detection signal or interrupts the detection before the connecting member 200 reaches the first position, the first display module 500 does not actually reach the target position (door opening position) and does not reach the target state (door opening state), after the set delay time, the first display module 500 can move to the target position to reach the target state, so that the connecting member 200 can actually reach the first position, ensuring the position stability of the fixed member 310 and the movable member 320 in the switch device 300. Therefore, the relay controls the on / off of the power supply and the first display module 500 and the second display module after the set delay time, changes the display status of the first display module 500 and the second display module, and can effectively solve the problem of inconsistent display status of the first display module 500 and the second display module.

Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
