Description
Technical Field
The utility model belongs to the technical field of electric doors and windows, and particularly relates to a trend sensing device and an electric door and window control system.
Background
At present, the opening or closing of the electric door and window in the market is mainly controlled by manual operation, specifically, the control switch forms a loop signal after touching the switch, the loop signal is fed back to the electric door and window system to form a motion instruction, and then the PCB drives the executing mechanism to further realize the automatic opening or closing of the door and window according to the motion instruction.
However, in actual use, there are the following drawbacks:
1. when the hands of the user cannot be released (or the fingers are inconvenient to move), the remote controller or the touch mode is very troublesome, and some of the hands need to be continuously controlled to implement the opening and closing operations of the door or window wanted by the user, so that the use flexibility is insufficient, and the use requirement cannot be met;
2. when the door or window is restarted after being interrupted (or stopped in the middle), if the door or window is not operated in time, reverse action can be generated, so that the probability of injury of a user caused by the movement of the door or window is higher; meanwhile, due to the contact mode adopted, high action errors (such as touch caused by wind blowing or touch caused by animals and the like) exist.
Disclosure of Invention
The utility model aims to overcome the defects of the prior art and provide an improved trend sensing device.
Meanwhile, the utility model also relates to an electric door and window control system.
In order to solve the technical problems, the utility model adopts the following technical scheme:
the trend sensing device comprises a contact switch and a touch rod, wherein the contact switch is in circuit communication with a power unit for automatically opening or closing a door and a window, in particular, the trend sensing device can be installed in the door and the window, and takes one end part of the touch rod as a rotation center, the rotation center and the door and the window synchronously rotate, the contact switch is provided with two groups of micro switches which are positioned at the left side and the right side of the touch rod, each group of micro switches is provided with at least one contact, the trend sensing device also comprises a left elastic component and a right elastic component which form motion damping and are abutted at the left side and the right side of the other end part of the touch rod, wherein when the touch rod is static, the left elastic component and the right elastic component are in dynamic balance, and the contact distances from the two sides of the touch rod to the micro switches of each group are equal; the motion damping is overcome, the touch rod deflects leftwards or rightwards, the contact of the micro switch at the same side is abutted against the touch rod, the left elastic component and the right elastic component form telescopic deformation, the power unit forms power to automatically open or close a door window at a constant speed or acceleration, and the contact is kept to be separated from the touch rod in the resetting process of the left elastic component and the right elastic component.
Preferably, the left elastic component and the right elastic component are symmetrically arranged on two opposite sides of the touch rod about the rotation center. The symmetrical layout is beneficial to the position stabilization of the touch rod in dynamic balance and reduces the instruction deviation probability caused by deflection. In some specific embodiments, the expansion and contraction amounts of the left elastic component and the right elastic component are equal, so that the probability of false touch caused in the deflection and resetting process of the touch rod is reduced more effectively, that is, reverse motion cannot be generated once the touch rod is interrupted, therefore, the probability of injury to a user is low, and meanwhile, the power unit forms power to open or close the door and window automatically in a uniform speed or acceleration mode according to the stress change of the touch rod.
According to a specific and preferred aspect of the utility model, the contact switch has two contacts, and the two contacts are symmetrically disposed on opposite sides of the touch lever with respect to the center of rotation. Here, the touch angles formed on both sides are the same.
In some embodiments, the connection line between the center of the other end of the touch rod and the center of the contact is a first center connection line, and the connection line between the center of the contact and the rotation center is a second center connection line, wherein the length of the first center connection line is greater than or equal to that of the second center connection line. Under this structural layout for left elastic component and right elastic component can increase the touch-rod resistance of deflecting, avoid appearing the maloperation.
According to a further specific and preferred aspect of the present utility model, the angle formed by the first and second centre lines on the left side and the angle formed by the first and second centre lines on the right side are equal when the lever is at rest. In some embodiments, when the touch bar deflects leftwards, the angle formed by the first central connecting line and the second central connecting line on the left side is larger than the angle formed by the first central connecting line and the second central connecting line on the right side; when the touch rod deflects rightwards, the angle formed by the first central connecting line positioned on the right side and the second central connecting line is larger than the angle formed by the first central connecting line positioned on the left side and the second central connecting line. The automatic opening and closing operation of the door and window is completed through the change of the opening angle, and meanwhile, the reset position of the touch rod is accurate under the equal angle.
In some embodiments, a third central connecting line between the rotation center and the center of the other end of the touch rod, when the touch rod deflects leftwards or rightwards, the length of the third central connecting line is equal, the deflection angle is +/-5 degrees, and when the deflection angle of the third central connecting line is +/-2 degrees, the power unit forms power to open or close the door and window at a constant speed; when the deflection angle of the third central connecting line is +/-2-5 degrees, the power unit forms power to accelerate the opening or closing of the door and window. Therefore, the trend sensing device can be compatible with two modes, and automatic opening and closing of doors and windows are realized: 1. full automatic mode; 2. semi-automatic mode (self-help/acceleration mode).
1. Full automatic mode
When a user touches the door and window, the touch rod compresses/stretches the elastic component, and then the corresponding micro switch is triggered. As the door and window are only touched instantaneously, once the hand leaves, the touch rod is reset along with the reset of the elastic component. But the trigger of the micro switch provides a pulse signal (voltage rising edge/voltage falling edge) to the PCB, and the PCB drives the actuating mechanism to execute the opening and closing functions, so that the opening or closing of the doors and windows is realized. The fully automatic mode at this time is the electric mode.
2. Semi-automatic mode (self-help mode/acceleration mode)
This time division is 2 cases: (1) is the habitual action of the user and always touches the door and window; (2) the user wants to accelerate the opening and closing of the door and window. At this time, the touch rod always compresses/stretches the elastic component, namely always triggers the corresponding micro switch, the trigger signal is continuous high level/low level, the PCB defaults to an acceleration mode according to the logic designed before, the opening or closing speed is accelerated, the power supply voltage is increased for the actuating mechanism, and further the movement of the door and window is driven faster. The semiautomatic mode (self-help/acceleration mode) at this time is a manual+electric mode.
Meanwhile, the allowable operating voltage of a general motor is a range, such as a 12V motor, and a general 9-16V motor can operate, but 12V is the best life test performance. If the full-automatic mode is that the 12V power supply motor works, the semi-automatic mode can be any voltage between 12V and 16V, the rotating speed of the motor is higher than that of the motor which is 12V, the opening and closing speed is higher, and the requirement that a user wants to accelerate opening and closing of doors and windows is met.
In addition, the resistance created by motion damping is greater than 2.5N. That is, the stiffness coefficient of the elastic component is within a reasonable range, so that on one hand, it is ensured that the elastic component cannot be compressed/stretched by misoperation such as natural wind, and on the other hand, it is ensured that children above a certain age can be easily compressed/stretched to generate misoperation.
Another technical scheme of the application: a control system for automatically opening or closing an electric door and window comprises a power unit, a hinge and a trend sensing device, wherein the rotation center of the trend sensing device rotates synchronously with the rotating shaft of the power unit and/or the chain shaft of the hinge. In this case, most of the electric doors and windows or window bodies on the market cannot be equipped with trend sensing devices in the actuator due to structural limitations and reliability requirements, which have to be placed at the door and window hinge. However, the conventional trend sensing device cannot be integrated at the hinge of the door and window due to the structural characteristics of the conventional trend sensing device. Therefore, the application provides a novel trend sensing device which can be integrated into an actuating mechanism or a door and window hinge. The device has the advantages of high reliability and cost performance, reasonable and compact structure, convenient installation, strong compatibility, suitability for various doors and windows and good universality. The method is applicable to various application scenes and has extremely high application value.
Due to the implementation of the technical scheme, compared with the prior art, the utility model has the following advantages:
the existing trend induction device is not only insufficient in flexibility and cannot meet the use requirement, but also has the probability of misoperation when being restarted after interruption (or in the middle of stopping), meanwhile, due to the adoption of a contact mode, the defect of high action error and the like exists, and the structure of the trend induction device is used for skillfully solving various defects of the existing structure. After the device is adopted, through the arrangement of motion damping, the deflection motion of the touch rod can more accurately implement uniform speed or acceleration automatic opening or closing of the door and window, meanwhile, the formed dynamic balance left elastic component and right elastic component are in reset to keep the contact from separating from the touch rod, so that the false action probability when the restarting is stopped in an interrupted or midway way is further reduced, on the one hand, the device has a reasonable and compact integral structure, the component is simple to set, the electric and intelligent levels of an actuating mechanism can be further improved, meanwhile, the aim that the trend sensing function is required to be additionally arranged on the existing door and window can be easily realized, the complexity of the system is reduced, the reliability of the system is improved, and the space is further saved; on the other hand, the door and window can be opened or closed at a uniform speed or with high speed under the power-assisted mode, so that the control requirements under different working conditions are met, the two hands can be released, the misoperation probability is low, meanwhile, the electric door and window is individualized and fashionable, can be suitable for various application scenes, has extremely high application value, in addition, does not need additional triggering and position detection, increases the stability of the system, saves the cost required by a conventional technical route, simultaneously avoids the situation that the trend sensing device cannot be additionally arranged due to the limitation of the space size of the original actuating mechanism, and further expands the application field of the electric door and window.

In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present application. This application is, however, susceptible of embodiment in many other forms than those described herein and similar modifications can be made by those skilled in the art without departing from the spirit of the application, and therefore the application is not to be limited to the specific embodiments disclosed below.
As shown in fig. 1 to 3, the automatic opening or closing control system for an electric door and window of the present embodiment includes a power unit, a hinge, and a trend sensor 1, wherein the rotation center of the trend sensor 1 rotates synchronously with the rotation axis of the power unit, and of course, the rotation center of the trend sensor 1 may also rotate synchronously with the chain shaft of the hinge, and the rotation center rotates synchronously with the door and window regardless of the implementation.
In some embodiments, the trend sensing device 1 includes a contact switch 10 and a touch lever 11, a left elastic component 12 and a right elastic component 13, wherein the contact switch 10 is in circuit communication with a power unit for automatically opening or closing a door and a window, the contact switch 10 has two micro switches with contacts 100 positioned on the left and right sides of the touch lever 11, each contact switch 10 has a micro switch with a contact 100, one end of the touch lever 11 is a rotation center m1, and the left elastic component 12 and the right elastic component 13 form motion damping and are abutted on the left and right sides of the other end of the touch lever 11.
When the touch rod 11 is at rest, the left elastic component 12 and the right elastic component 13 are in dynamic balance, the distances from the two sides of the touch rod 11 to the contacts 100 of each group of microswitches are equal, and the resistance provided by the motion damping formed by the left elastic component 12 and the right elastic component 13 is greater than 2.5N. In general, the stiffness coefficient is in a reasonable range between 2.5 and 3.75N, so that on one hand, the false actions such as natural wind and the like can not be compressed/stretched, and on the other hand, the false actions can be generated by ensuring that children above a certain age can be easily compressed/stretched. In short, when overcoming the motion damping, the touch bar 11 can deflect to the left or right to implement contact automatic opening or closing of the door and window, and the left and right elastic members 12 and 13 employ a conventional spring, and maintain the contact separated from the touch bar 11 in a return formed by compression/extension of the spring.
In some embodiments, two contacts 100 are symmetrically disposed on opposite sides of the lever 11 about the center of rotation m1, and the left elastic member 12 and the right elastic member 13 are symmetrically disposed on opposite sides of the lever about the center of rotation m 1.
In some embodiments, a connection line between the center m2 of the other end portion of the touch rod 11 and the contact center m3 is a first center connection line x1, a connection line between the contact center m3 and the rotation center m1 is a second center connection line x2, and a connection line between the center m2 of the other end portion of the touch rod 11 and the rotation center m1 is a third center connection line x3, wherein the length of the third center connection line x3, the length of the first center connection line x1, and the length of the second center connection line x2 become smaller in sequence, and form an obtuse triangle, and when the touch rod 11 is at rest, the obtuse angles of the two obtuse triangles are equal; when the touch bar 11 deflects leftwards, the angle formed by the first central connecting line x1 and the second central connecting line x2 positioned at the left side is larger than the angle formed by the first central connecting line x1 and the second central connecting line x2 positioned at the right side; when the touch lever 11 deflects rightward, the angle formed by the first central line x1 and the second central line x2 on the right side is larger than the angle formed by the first central line x1 and the second central line x2 on the left side.
Further, when the touch rod 11 deflects leftwards or rightwards, the length of the third central connecting line x3 is equal, the deflection angle is +/-5 degrees, and when the deflection angle of the third central connecting line x3 is +/-2 degrees, the power unit forms power to open or close the door and window at a constant speed; when the deflection angle of the third central connecting line is +/-2-5 degrees, the power unit forms power to accelerate the opening or closing of the door and window. Therefore, the trend sensing device can be compatible with two modes, and automatic opening and closing of doors and windows are realized: 1. full automatic mode; 2. semi-automatic mode (self-help/acceleration mode).
1. Full automatic mode (with reference to FIG. 2)
When a user touches the door and window, the touch rod compresses/stretches the elastic component, and then the corresponding micro switch is triggered. As the door and window are only touched instantaneously, once the hand leaves, the touch rod is reset along with the reset of the elastic component. But the trigger of the micro switch provides a pulse signal (voltage rising edge/voltage falling edge) to the PCB, and the PCB drives the actuating mechanism to execute the opening and closing functions, so that the opening or closing of the doors and windows is realized. The fully automatic mode at this time is the electric mode.
2. Semi-automatic mode (self-help mode/acceleration mode, combined with FIG. 3)
This time division is 2 cases: (1) is the habitual action of the user and always touches the door and window; (2) the user wants to accelerate the opening and closing of the door and window. At this time, the touch rod always compresses/stretches the elastic component, namely always triggers the corresponding micro switch, the trigger signal is continuous high level/low level, the PCB defaults to an acceleration mode according to the logic designed before, the opening or closing speed is accelerated, the power supply voltage is increased for the actuating mechanism, and further the movement of the door and window is driven faster. The semiautomatic mode (self-help/acceleration mode) at this time is a manual+electric mode.
Meanwhile, the allowable operating voltage of a general motor is a range, such as a 12V motor, and a general 9-16V motor can operate, but 12V is the best life test performance. If the full-automatic mode is that the 12V power supply motor works, the semi-automatic mode can be any voltage between 12V and 16V, the rotating speed of the motor is higher than that of the motor which is 12V, the opening and closing speed is higher, and the requirement that a user wants to accelerate opening and closing of doors and windows is met.
In summary, the process of automatically opening and closing the door and window is as follows:
when a user touches the door and window, the touch rod compresses/stretches the elastic component, and simultaneously deflects to the left or right by 2 degrees, the corresponding micro switch is triggered, a pulse signal (voltage rising edge/voltage falling edge) is provided for a PCB (power unit) after the micro switch is triggered, and then the PCB (power unit) drives the actuating mechanism to execute the opening and closing function, so that power is formed to open or close the door and window at a constant speed; when a user always touches the door and window due to habitual actions, once the door and window is deflected leftwards or rightwards by 3 degrees and the angle is gradually increased to 5 degrees or stays at 3-5 degrees, the touch rod always compresses/stretches the elastic component, namely the corresponding micro switch is always triggered, the trigger signal is continuously high level/low level, the PCB (power unit) is in an acceleration mode at the moment by default according to the logic designed before, the opening or closing speed of the door and window is accelerated, the power supply voltage is increased for the actuating mechanism, and then the movement of the door and window is driven faster.
Therefore, after the device is adopted, through the arrangement of motion damping, the deflection motion of the touch rod can more accurately implement uniform speed or acceleration automatic opening or closing of the door and window, and meanwhile, the formed dynamic balance left elastic component and right elastic component are in reset to keep the contact separated from the touch rod, so that the false operation probability when the restarting is stopped or stopped halfway is further reduced, on the one hand, the device has a reasonable and compact integral structure, the component is simple to set, the electric and intelligent levels of an actuating mechanism can be further improved, meanwhile, the aim that the trend sensing function of the existing door and window is required to be additionally arranged can be easily realized, the complexity of the system is reduced, the reliability of the system is improved, and the space is further saved; on the other hand, the door and window can be opened or closed at a constant speed or in an acceleration mode, so that the control requirements under different working conditions are met, the two hands can be released, the false action probability is low, meanwhile, the door and window is fashionable, and the door and window opening device is suitable for various application scenes and has extremely high application value; in the third aspect, no additional triggering and position detection are needed, the stability of the system is improved, the cost required by a conventional technical route is saved, meanwhile, the problem that a trend sensing device cannot be additionally arranged due to the limitation of the space size of the original actuating mechanism is avoided, and the application field of the electric door and window is further expanded; in the fourth aspect, the device can be integrated into an actuating mechanism and a door and window hinge, has high reliability and cost performance, reasonable and compact structure, convenient installation, strong compatibility and good universality, and is suitable for various doors and windows.
