Detailed Description
The invention is further described with reference to the drawings and the specific embodiments.
Referring to fig. 1, 2 and 3, this embodiment discloses an elevator door, and it can be understood that the elevator door of this embodiment can be installed on an elevator car, and can also be installed on a floor for taking an elevator, including:
the door comprises a first glass 110 and a second glass 120, wherein the first glass 110 and the second glass 120 form a door body 130 of the elevator door. Generally, tempered glass is selected to ensure the strength of the first glass 110 and the second glass 120, and an explosion-proof film may be attached to the elevator door to prevent the tempered glass from breaking and breaking.
The liquid crystal dimming film 140 is provided in the interlayer formed by the first glass 110 and the second glass 120. The liquid crystal dimming film is a panel mainly composed of a liquid crystal material, wherein the liquid crystal material exhibits a random alignment direction when an electric field is not applied thereto, and thus light cannot pass through the liquid crystal material, and the liquid crystal material is aligned in a certain direction when an electric field is applied thereto, and at this time, the liquid crystal material exhibits light transmittance in some directions. In fig. 4, the liquid crystal light adjusting film is in a state where an electric field is not applied, and the arrangement of liquid crystal molecules is disordered and light cannot pass through. Fig. 5 shows a state of the liquid crystal light adjusting film when an electric field is applied thereto, in which liquid crystal molecules are aligned in one direction and light can pass therethrough. Of course, some liquid crystal materials are regularly arranged under the condition that no electric field is applied, and the arrangement direction of the liquid crystal materials can be changed through the electric field, so that the light transmission state in certain directions is changed.
A driving circuit (not shown) for driving the liquid crystal dimming film 140 to change the light transmission state. It is to be understood that the light transmission state includes transparent and opaque, wherein the opaque can be frosted gray or partially opaque, so as to display characters or patterns, etc., which is the same as the display principle of the common liquid crystal dimming film. Based on the electric effect of the liquid crystal, the liquid crystal is switched between transparent and non-transparent by changing the power-on condition of the liquid crystal dimming film. It is understood that the liquid crystal dimming film can be designed in an array form, and the driving circuit can control the light transmission state of each liquid crystal unit (pixel) through a plurality of control lines. In this scenario, the lower half of the elevator door is switched between transparent and non-transparent by controlling the liquid crystal dimming film, as shown in figure 1. In this scenario, the elevator door is switched between being completely transparent and displaying a warning pattern by controlling the liquid crystal dimming film, as shown in fig. 2. Specifically, if the liquid crystal dimming film has only two states of light transmission and non-light transmission, the driving circuit can be realized only by adopting a common switching circuit. On the other hand, if the liquid crystal dimming film has a multi-pixel structure similar to that of the liquid crystal dimming film of the display, a driving circuit of the liquid crystal display of the display needs to be used.
A fixing mechanism for fixing the first glass and the second glass. Referring to fig. 3, in general, a fixing mechanism mostly adopts a wrapping structure, and is used for fixing glass on one hand, and on the other hand, a user protects the edge of the glass to avoid the glass from cracking due to collision and crushing the glass. The securing mechanism may surround the entire edge of the first and second glasses, forming a metallic door frame. Usually, a pulley, a guide groove and other structures can be installed on the fixing mechanism, so that a driving mechanism on an elevator car or a floor door frame can drive the elevator door to move.
In some embodiments, the liquid crystal dimming film 140 includes a first film 141, a second film 142, and a liquid crystal layer 143, and the liquid crystal layer 143 is sandwiched between the first film 141 and the second film 142.
In some embodiments, the first and second films are both PVB films. PVB is also known as polyvinyl butyral. The prepared film is used for preparing an interlayer material of safety glass, and the safety glass has good transparency.
In some embodiments, the first glass and the second glass are both tempered glasses, and the first glass and the second glass are both light-transmitting glasses. In general, colorless tempered glass is used as the first glass and the second glass. The light transmission is good, and the sightseeing effect of passengers is not influenced.
In some embodiments, the liquid crystal dimming film has an area smaller than that of the first glass, and the liquid crystal dimming film is disposed at a lower half portion of the elevator door. In this embodiment, the liquid crystal dimming film is located at the lower half part of the elevator door, and it can be understood that the part of the elevator door below the boundary is controlled by the liquid crystal dimming film to be in a light transmission state, and the upper part of the elevator door is completely transparent. The scheme can reduce the area of the liquid crystal light adjusting film under the condition of meeting the requirement, thereby reducing the cost.
In some embodiments, the liquid crystal dimming film has a height greater than 1.1 meters, wherein the height of the liquid crystal dimming film is the distance between one end of the liquid crystal dimming film near the top of the elevator door and one end near the bottom of the elevator door. 1.1 m height setting mainly is the height of considering children, in some scenes, for example when opening the door, makes glass atomizing to warn child, reduce the risk that child's hand was dragged.
In some embodiments, when the door is opened or closed, the liquid crystal dimming film can be informed to display a specific pattern, and a prompt tone is generated by arranging a loudspeaker to prompt a passenger not to touch the door of the elevator.
In some embodiments, the drive circuit is provided with a communication interface, which is connected with an electrical box of the elevator car. Generally, an interface, such as a 485 communication interface, which can transmit control signals, can be used to connect the electrical box of the elevator car with the drive circuit, so as to control the state of the elevator door by the electrical box of the elevator car. It is to be understood that the electrical box may also supply power to the drive circuit via the communication interface.
Referring to fig. 6, the present embodiment discloses an elevator including a car 210 and an elevator door 220 installed on the car. The car 210 is further provided with a driving mechanism (not shown) for driving the elevator door 220 to open and close. Wherein the cage refers to a box structure which runs up and down in an elevator shaft and is used for bearing passengers. The elevator door of the present embodiment means a door mounted on a car.
While the preferred embodiments of the present invention have been described, the present invention is not limited to the above embodiments, and those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention, and such equivalent modifications or substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
