[0036] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0037] The method embodiment provided in this embodiment can be executed in a terminal, a computer or a similar computing device. For example, running on a terminal, Figure 1 FIG. 1 is a hardware structure block diagram of a terminal of a door control method according to an embodiment of the present application. Figure 1 As shown, the terminal may include one or more ( Figure 1 Only one is shown in the figure) processor 102 and memory 104 for storing data, wherein processor 102 may include but is not limited to a processing device such as a microprocessor MCU or a programmable logic device FPGA. The above terminal may also include a transmission device 106 and an input and output device 108 for communication functions. It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above terminal. Figure 1 More or fewer components as shown, or with Figure 1 Different configurations shown.

[0038] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the door control method in this embodiment. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some examples, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the terminal via a network. Examples of the above network include, but are not limited to, the Internet, an intranet, a local area network, a mobile communication network, and combinations thereof.

[0039] The transmission device 106 is used to receive or send data via a network. The above network includes a wireless network provided by the communication provider of the terminal. In one example, the transmission device 106 includes a network adapter (Network Interface Controller, referred to as NIC), which can be connected to other network devices through a base station so as to communicate with the Internet. In one example, the transmission device 106 can be a radio frequency (Radio Frequency, referred to as RF) module, which is used to communicate with the Internet wirelessly.

[0040] In one embodiment, the door body includes a flip beam, and a first level signal is generated when the flip beam is in a flip state. The flip state is used to indicate that the angle between the flip beam and the door panel is greater than or equal to a preset angle or the distance between the flip beam and the door panel exceeds a preset distance. Optionally, the state of the flip beam can be identified by a position detection device, and the position detection module may include an electromagnetic induction device installed on the flip beam. When the flip beam is in a flip state and other states, the electromagnetic induction device outputs a corresponding level signal based on different electromagnetic induction intensities according to different electromagnetic induction intensities. Alternatively, the position detection module may also be other devices for detecting the relative position between two objects, including but not limited to visual recognition systems, encoders, and the like.

[0041] like Figure 2 As shown, a door control method is provided, which is applied to Figure 1 The terminal in is used as an example to illustrate, including the following steps:

[0042] Step S202, driving the door to move, so as to perform an opening action or a closing action of the door.

[0043] Among them, the door body has the function of automatic door opening and closing, and can input signals to the driving device of the door body based on user instructions or based on the demand for opening and closing the door, so as to realize automatic door opening and closing. Optionally, when the door body is the door of a device such as a refrigerator, it can be determined whether to perform the door opening action or the door closing action according to the internal condition of the device box; when the door body is a sensor door, it can perform the automatic door opening or closing action according to the regional sensing result. Optionally, the input of user instructions can be realized by buttons, switches, devices connected to the terminal communication, etc., so that the terminal drives the door body to move.

[0044] Step S204, receiving a signal generated by the flip beam.

[0045] Optionally, after the door body is driven to move, the terminal receives the signal generated by the flip beam. Alternatively, the terminal may receive the signal generated by the flip beam while executing the step of driving the door body to move.

[0046] Step S206: If the first level signal generated by the flip beam is received, the door body is stopped from being driven.

[0047] Among them, when the first level signal generated by the flip beam is generated, the terminal can determine that the flip beam is in a flip state. If the door body is in the process of opening the door, the flip beam in the flip state is raised, which may cause harm to the user; if the door body is in the process of closing the door, the flip beam in the flip state will affect the closing of the door body. If the door body is closed forcibly, it may cause damage to the door body.

[0048] Optionally, it is identified whether the signal generated by the flip beam is a first level signal. If not, the door closing action continues until the door is completely closed, or the door opening action continues until the door is opened to a preset position.

[0049] In the above-mentioned door control method, when the refrigerator executes the door opening action or the door closing action, it is obtained and identified whether the signal output by the flip beam is a first level signal. When the signal output by the flip beam is a first level signal, the execution of the refrigerator door opening or closing action is controlled to be terminated, thereby avoiding the position deviation of the flip beam, which may cause the door to not be fully opened, closed or damaged, thereby improving the reliability and safety of the automatic opening and closing process of the door body with a flip beam.

[0050] It should be understood that, although the steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence as indicated by the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the above-mentioned embodiments may include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be executed in turn or alternately with other steps or at least a portion of the steps or stages in other steps. For example, while executing step S202 and step S206, step S204 can be synchronously executed to receive the signal generated by the flip beam, thereby achieving real-time reception of the signal.

[0051] In one embodiment, a second level signal is generated when the flip beam is in a closed state. If a first level signal generated by the flip beam is received, the driving of the door body is stopped. The method also includes: when the level signal generated by the flip beam is received and changes from the first level signal to the second level signal, and the second level signal is continuously received within a first preset time, the door body continues to be driven to move.

[0052] The closed state is used to indicate that the angle between the flip beam and the door panel is less than a preset angle, or the distance between the flip beam and the door panel is less than a preset distance. Alternatively, the closed state may also be the state of the flip beam when the door body is completely closed. Optionally, when the state of the flip beam is recognized by the position detection device, the position detection module detects that the distance between the flip beam and the door panel is less than a preset distance, then the position detection module generates a second level signal and transmits the second level signal to the terminal.

[0053] Among them, when the flip beam level signal changes from the first level signal to the second level signal, the terminal can judge that the flip beam of the door body changes from the flip state to the closed state according to the second level signal. In order to ensure that the level signal received by the terminal is accurate, when the second level signal is continuously received for the first preset time, it is judged that the door body opening action or the door body closing action can be continued. The first preset time can be set or modified according to needs.

[0054] In this embodiment, after the door body stops moving, it is determined whether the door body can continue to be opened and closed by detecting the level signal, thereby ensuring that the door body can realize the automatic opening or closing function.

[0055] Furthermore, in one embodiment, driving the door body to move includes: inputting a door opening signal to a driving motor of the door body to perform a door opening action; or inputting a door closing signal to the driving motor to perform a door closing action. Optionally, by inputting a signal to the driving motor, when receiving a first level signal generated by the flip beam, the output of the door opening signal or the door closing signal to the driving motor is stopped, so that the driving motor stops running, and the door body stops moving and stays in place. In this embodiment, the movement of the door body is controlled by the driving motor, so that the door body can stop moving at any time.

[0056] In one embodiment, a second level signal is generated when the flip beam is in a closed state, and driving the door body to move to perform the door opening action includes: when the second level signal is continuously received within a second preset time, driving the door body to perform the door opening action.

[0057] Optionally, before driving the door body to perform the door opening action, it is determined whether a second level signal with a duration greater than or equal to a second preset time is received. If so, the flip beam is in a closed state, and it is safer for the door body to perform the door opening action. If not, the flip beam is in a flipping state, and the flip beam will bulge when the door body starts, which may easily hurt the user. The third preset time is set according to demand.

[0058] In this embodiment, whether the door opening action can be performed is determined according to the second level signal, which can achieve the effect of improving the safety of the door control method.

[0059] In one embodiment, if the first level signal generated by the flip beam is received, stopping driving the door body includes: stopping driving the door body when the first level signal is continuously received within a third preset time. The third preset time is set according to demand. By determining whether the duration of the second level signal is greater than or equal to the third preset time, the stability and reliability of the door body control method can be improved.

[0060] Furthermore, when the flip beam is in a closed state, a second level signal is generated, and the fourth preset time is greater than or equal to the third preset time. When the first level signal is continuously received within the third preset time, after the door body is stopped from being driven, the method also includes: when the first level signal is continuously received within the fourth preset time, an alarm message is generated until the level signal generated by the flip beam is received and changes from the first level signal to the second level signal, and the generation of the alarm message is stopped.

[0061] Wherein, when the first level signal is continuously received for a period of time greater than or equal to the fourth preset time, it is determined that the flip beam position is offset and cannot be restored to the closed state within the fourth preset time, and an alarm message is generated to prompt the user to pay attention to the flip beam state. The alarm message may be a sound, light, or electrical signal. Optionally, the alarm may be realized by a buzzer or an indicator light, and the alarm message may also be transmitted to a user device connected to the terminal.

[0062] Optionally, when the terminal receives a first level signal output by the position detection device of the flip beam for a set time and determines that the flip beam is in a flip state, the terminal transmits the status data of the flip beam to the alarm device. The first level signal of the set time can be 1 minute or other time. A warning sound is emitted by the buzzer in the alarm device to remind the user that the flip beam is in a flipped open state. After the user manually closes it, the warning sound is turned off. When there is no manual processing by the user, the warning sound is automatically turned off after a specified time. Among them, the specified time can be 1 minute or other time.

[0063] Optionally, when the terminal receives the output of the flip beam, which changes from the first level signal to the second level signal, and continues to receive the second level signal of another set time, it is determined that the flip beam is in a closed state. Among them, the second level signal of another set time can be 1 second or other time. The terminal transmits the data to the display alarm unit, and the buzzer sounds for 3 seconds, indicating that the flip beam has returned to the closed state. The time for the buzzer to sound can be set according to needs and is not limited here.

[0064] In this embodiment, the corresponding alarm information is output according to the level signal, which can improve the safety during the door opening and closing process.

[0065] In one embodiment, the flip beam is equipped with a position sensing device, through which the flip beam can be detected to be in a flipped state or a closed state. Optionally, the position sensing device outputs a first level signal when the flip beam is detected to be in a flipped state, and outputs a second level signal when the flip beam is detected to be in a closed state. The first level signal and the second level signal are different in height.

[0066] Optionally, taking the flip beam of a refrigerator as an example, taking the first level signal as a high level signal, and the second level signal as a low level signal, and taking the main control unit of the refrigerator as an example, the main control unit of the refrigerator can execute an emergency protection mechanism for opening and closing the door based on the position sensing device of the flip beam: when the drive motor of the refrigerator door is performing automatic door opening or closing, as long as the main control unit receives a high level signal from the position sensing device and the duration is greater than the third preset time, the main control unit outputs a signal to the drive motor of the door, thereby immediately stopping the automatic door opening or closing action of the refrigerator, so as to effectively protect the mechanical reliability of the flip beam.

[0067] Further, Figure 3 Provides an automatic door closing control logic:

[0068] Step S301: When the refrigerator is closing its door, the main control unit detects a high-level signal output by the position sensing device, and the main control unit sends a signal to control the drive motor to stop working, and the automatic door closing action stops. In the case of a high-level signal output by the sensing device, it can be determined that the flip beam is in a flipping state, and if the door closing action is continued, it will cause damage to the refrigerator.

[0069] Step S302: When the high level signal is retained for a fourth preset time, the alarm mechanism is activated.

[0070] Step S303, after the main control unit receives the signal output by the position sensing device that changes from a high level signal to a stable low level signal for the first preset time, the alarm mechanism stops, and the main control unit sends a door closing signal to the drive motor to perform an automatic door closing action. Optionally, the first preset time can be set to 1 second, the fourth preset time can be set to 1 minute, and the first preset time and the fourth preset time can also be set to other values.

[0071] Figure 4 Provides an automatic door opening control logic:

[0072] Step S401, when there is a need to open the door of the refrigerator, after the main control unit detects a low-level signal that lasts for a second preset time, it is determined that the refrigerator can open the door. Wherein, when the main control unit detects a low-level signal that lasts for the second preset time, it can be determined that the flip beam is in a closed state, thereby improving the safety of the refrigerator when automatically opening the door.

[0073] Step S402: the main control unit sends a signal to cause the drive motor to start working and execute the refrigerator door opening action.

[0074] Step S403, during the refrigerator door opening process, after the main control unit receives a high-level signal output by the position sensing device and the duration is greater than or equal to the third preset time, the main control unit outputs a signal to the drive motor to stop the drive motor and keep the drive motor at the current position. Optionally, the third preset time is set to 100ms, and the third preset time can also be set to other values.

[0075] Step S404, after the main control unit receives the signal output by the position sensing device which changes from a high level signal to a stable low level signal for a second preset time, the main control unit sends a door opening signal to the drive motor to continue to perform the door opening action.

[0076] It can be understood that the door control method in this embodiment can also be applied to other devices besides refrigerators, including but not limited to automatic doors, cabinet doors, etc.

[0077] In this embodiment, the reliability and safety of the refrigerator door opening and closing with automatic door opening or closing is achieved by detecting the flip position state. How to use the position state of the flip beam to control the reliability and safety of the refrigerator door opening and closing with automatic door opening or closing.

[0078] Based on the same inventive concept, the embodiment of the present application also provides a door body for implementing the door body control method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more door body embodiments provided below can refer to the limitations of the door body control method above, and will not be repeated here.

[0079] In one embodiment, Figure 5 As shown, a door control system is provided, including: a flip beam, a door panel, a position detection module and a control module; wherein the position detection module is used to generate a first level signal when the flip beam is in a flipping state, and to generate a second level signal when the flip beam is in a closed state; the control module is used to drive the door body to move to perform an opening action or a closing action of the door body; and receive the signal generated by the flip beam, and stop driving the door body if the first level signal generated by the flip beam is received.

[0080] In one embodiment, the position detection module includes a transmitting unit and a receiving unit, the transmitting unit is arranged in the flip beam, and the receiving unit is arranged in the door panel; wherein, when the flip beam is in a closed state, the receiving unit can receive the signal generated by the transmitting unit and output a first level signal to the control module; when the flip beam is in a flipping state, the receiving unit cannot receive the signal generated by the transmitting unit and outputs a second level signal to the control module.

[0081] Wherein, the receiving module and the transmitting module are arranged correspondingly. Optionally, the position detection device is a detection induction detection device. Figure 6 A structural schematic diagram of a position detection module is provided. Figure 6 (a) is a schematic diagram of the position detection module when the flip beam flips 90 degrees. Figure 6 (b) is a schematic diagram of the position detection module when the flip beam is closed. The transmitting module and the receiving module are set correspondingly. Among them, the electromagnetic induction coil transmitting module is installed on the inner side of the flip beam, and the coil is connected to alternating current; the electromagnetic induction magnetic field receiving module is pre-buried and installed in the inner liner of the door body, and the electromagnetic induction magnetic field receiving module includes an electromagnetic induction receiving chip and a circuit board arranged around the chip.

[0082] Alternatively, if Figure 6 As shown in (a), when the flip beam flips, the transmitting module and the receiving module are separated and are in a 90-degree vertical state. The electromagnetic induction receiving module cannot receive the signal output by the transmitting module. At this time, the receiving module performs signal conversion and outputs a high-level signal to the control module. The control module determines that the flip beam is in a flip state based on the received high-level signal.

[0083] like Figure 6 As shown in (b), when the flip beam is closed, the transmitting module and the receiving module are parallel, and the distance between them is less than the set value D. The electromagnetic induction receiving module receives the signal output by the transmitting module, and at this time, the receiving module performs signal conversion and outputs a low-level signal to the main control unit. The control module determines that the flip beam is in a closed state according to the received high-level signal.

[0084] In one embodiment, the door control system further includes a voice module, which is used to output a preset voice when the control module receives a first level signal generated by the flip beam.

[0085] Optionally, the voice module can be a buzzer, or a speaker, a player, or other equipment. When the control module continuously receives the first level signal from the receiving module within the fourth preset time of the receiving module, the control module generates an alarm message. Generating the alarm message includes inputting a signal to the voice module, and outputting a preset voice through the voice module to realize the alarm. The control module continuously generates the alarm message until the level signal generated by the flip beam is received and changes from the first level signal to the second level signal, and stops generating the alarm message. The voice module stops outputting the preset voice.

[0086] In one embodiment, a second level signal is generated when the flip beam is in a closed state. If a first level signal generated by the flip beam is received, the door body is stopped from being driven. The control module execution method also includes: when the level signal generated by the flip beam is received and changes from the first level signal to the second level signal, and the second level signal is continuously received within a first preset time, the door body continues to be driven to move.

[0087] Optionally, the control module drives the door body to move to perform the door opening action, including: driving the door body to perform the door opening action when the second level signal is continuously received within a second preset time.

[0088] In one embodiment, when the control module receives the first level signal generated by the flip beam, stopping driving the door body includes: stopping driving the door body when the first level signal is continuously received within a third preset time.

[0089] Furthermore, when the flip beam is in a closed state, a second level signal is generated, and the fourth preset time is greater than or equal to the third preset time. When the first level signal is continuously received within the third preset time, after the door body is stopped from being driven, the control module execution method also includes: when the first level signal is continuously received within the fourth preset time, an alarm message is generated until the level signal generated by the flip beam is received and changes from the first level signal to the second level signal, and the generation of the alarm message is stopped.

[0090] In one embodiment, the control module drives the door body to move including: inputting a door opening signal to a driving motor of the door body to perform a door opening action; or inputting a door closing signal to the driving motor to perform a door closing action.

[0091] Each module in the above-mentioned door control system can be implemented in whole or in part by software, hardware and a combination thereof. Each of the above-mentioned modules can be embedded in or independent of a processor in a computer device in the form of hardware, or can be stored in a memory in a computer device in the form of software, so that the processor can call and execute the operations corresponding to each of the above modules.

[0092] Based on the same inventive concept, the embodiment of the present application also provides a refrigerator for implementing the door control method involved above, wherein the refrigerator comprises a cabinet, a door, and the door control system in the above system embodiments.

The position detection module is arranged on the flip beam, and the control module is connected to the driving motor of the door body. The control module can implement the steps in the above-mentioned method embodiments.

[0094] The solution provided by the refrigerator to solve the problem is similar to the solution described in the above method, so the specific limitations in the refrigerator embodiment provided below can refer to the limitations on the door control method above, and will not be repeated here.

Among them, the processor of the computer device is used to provide computing and control capabilities. The memory of the computer device includes a non-volatile storage medium and an internal memory. The non-volatile storage medium stores an operating system, a computer program and a database. The internal memory provides an environment for the operation of the operating system and the computer program in the non-volatile storage medium. The database of the computer device is used to store the level signal output by the flip beam and the corresponding time and other data required to execute the door body control method. The input / output interface of the computer device is used to exchange information between the processor and the external device. The communication interface of the computer device is used to communicate with an external terminal through a network connection. When the computer program is executed by the processor, a door body control method is implemented.
