Description

Technical Field

[0001] This utility model relates to elevator systems, and in particular to an elevator floor display. Background Technology

[0002] In elevator systems, floor displays are needed to alert passengers when the elevator car arrives at each floor. These displays are typically located above or to the side of the elevator doors. Currently, multiple elevators are often densely packed in different areas of a building, making it difficult for passengers to promptly observe changes in the floor displays and the opening and closing of the elevator doors. This forces passengers to frequently move around and check multiple elevator doors to avoid missing a ride. Even when a building has only one elevator, the small size of the floor display due to a large number of passengers can make it difficult for passengers further back to notice changes in the display, hindering convenient elevator access.

[0003] To improve the illuminating capabilities of elevator floor displays, some elevators have larger displays for easier observation. However, current elevator floor displays often use light-emitting diode (LED) screens, which are expensive and consume a lot of power, resulting in higher current-carrying requirements for the wiring. Increasing the size of the LED screen would raise elevator costs and operating costs, and also increase the risk of elevator circuit overload, posing a significant obstacle to practical application.

[0022] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0023] The elevator floor display protected by this utility model includes an indicator background 2 and a dimming glass 3. Multiple elevator floor displays are respectively connected to the walls 102 of each floor of the building and correspond one-to-one with each elevator door 101. The dimming glass 3 is disposed on the side of the indicator background 2 away from the wall 102. The dimming glass 3 is electrically connected to the elevator controller and can controllably switch between a light-blocking state and a light-transmitting state. When the dimming glass 3 is in a light-blocking state or a light-transmitting state, it works with the indicator background 2 to form a floor mark 103. The floor mark 103 is used to indicate the floor number corresponding to the elevator floor display.

[0024] The dimming glass 3, in its light-blocking state, partially or completely blocks the indicator background 2. Whether in a light-blocking or light-transmitting state, the surface of the dimming glass 3 displays the graphic of the floor indicator 103 in conjunction with the indicator background 2, thus indicating the arrival of the elevator car. The dimming glass 3 has low cost and low power consumption, resulting in low cost per unit area and facilitating the scaling up of elevator floor displays.

[0025] In some embodiments, a floor marker 103 is formed on the side of the indicator background 2 near the dimming glass 3, and the dimming glass 3 completely covers the floor marker 103. When the elevator car arrives at the floor corresponding to the elevator floor display, the dimming glass 3 switches to a light-transmitting state.

[0026] The floor identifier 103 is a special graphic with an indicative function, such as numbers, indicating the floor number corresponding to the elevator floor display. The floor identifier 103 is covered by a dimming glass 3. When the car arrives, the dimming glass 3 switches to a light-transmitting state, and the elevator floor display shows the floor where the passenger is currently located, serving as a reminder.

[0027] In some embodiments, the elevator floor display is disposed on the side of the elevator door 101, and its vertical height is any value between 1.0m and 2.0m, such as 1.0m, 1.2m, 1.4m, 1.8m, 1.8m, and 2.0m. When the height of the elevator floor display is large, its width and surface area are also large. Distributing it on the side of the elevator door 101 allows passengers to observe changes in the elevator floor display from a greater distance and at a larger angle, thus providing a stronger indication effect.

[0028] In some embodiments, the elevator floor display is positioned opposite the elevator door 101, with a vertical height of any value between 0.5m and 1.0m, such as any value among 0.5m, 0.6m, 0.7m, 0.8m, 0.9m, and 1.0m, and its vertical centerline height is any value between 1.4m and 1.8m, such as any value among 1.4m, 1.5m, 1.6m, 1.7m, and 1.8m. Positioning the elevator floor display at a high position opposite the elevator door 101 facilitates observation by passengers waiting in the elevator car and also allows passengers inside the elevator car to easily observe the floor the elevator has reached.

[0029] In some embodiments, the elevator floor display also includes a support plate 4. The support plate 4 is a plate-like structure with multiple elongated perforations on its surface. Multiple dimming glass panels 3 are embedded in the perforations of the support plate 4, closing the perforations and forming a seven-segment digital graphic. Each of the dimming glass panels 3 is electrically connected to and independently controlled by a controller. By partially energizing the dimming glass panels 3 that form the seven-segment digital graphic, the background 2 is partially obscured, thereby displaying different numbers to indicate the floor corresponding to the current elevator car.

[0030] In some embodiments, multiple marking units form an upward marking and a downward marking 105, respectively, to indicate the upward or downward movement of the car. The upward marking and the downward marking 105 display the current direction of travel of the car, making it easier for passengers to understand the car's operating status.

[0031] In some embodiments, the surface of the indicator background 2 near the carrier plate 4 is configured with a first solid color, the carrier plate 4 is constructed as a light-shielding structure, and the surface of the indicator background 2 away from it is configured with a second solid color, the first solid color and the second solid color being different colors.

[0032] The supporting plate 4 and the dimming glass 3 forming a seven-segment digital graphic jointly block the indicator background 2. When the dimming glass 3 is in a light-blocking state, the elevator floor display surface displays a second solid color with a seven-segment digital graphic in the center. When the dimming glass 3 partially transmits light according to the floor corresponding to the car, the elevator floor display surface displays a first solid color digital graphic, thereby flexibly displaying a variety of different floor signs 103 to indicate the current position of the car.

[0033] In some embodiments, the carrier plate 4 is constructed as a light-transmitting structure. When the dimming glass 3 is in a light-blocking state, it displays a third solid color, and the background 2 is configured with a fourth solid color near the surface of the carrier plate 4. The third solid color and the fourth solid color are different colors.

[0034] When the three sections of the dimming glass that form the seven-segment digital graphic are switched to the light-blocking state, the elevator floor display shows the digital graphic of the third solid color, thus indicating the current position of the elevator car.

[0035] In some embodiments, an illumination element 5 is provided between the indicator background 2 and the dimming glass 3. The illumination element 5 is electrically connected to the dimming glass 3, and the illumination element 5 is controllably turned on when the dimming glass 3 is in a light-transmitting state. This helps to improve the visibility of the elevator floor display.

[0036] In some embodiments, the elevator floor display also includes a mounting frame 1, with the indicator background 2 and the dimming glass 3 both connected to the mounting frame 1, and the mounting frame 1 embedded in the wall 102.

[0037] Please refer to the following examples for details.

[0038] Example 1: Please see Figure 1 and Figure 2 The elevator floor display shown in a preferred embodiment of this application includes a mounting frame 1, an indicator background 2, and a dimming glass 3. The indicator background 2 and the dimming glass 3 are embedded within the mounting frame 1.

[0039] The mounting frame 1 is constructed as a rectangular frame structure, including a first limiting surface 11, a second limiting surface 12, and a connecting surface 13. The first limiting surface 11 and the second limiting surface 12 are identical rectangular annular structures and are arranged parallel to each other. The connecting surface 13 is perpendicular to the first limiting surface 11 and connects to the outer edges of the first limiting surface 11 and the second limiting surface 12, forming a rectangular annular groove opening inwards. The overall height of the mounting frame 1 is 1.5m, the width is 1.2m, and the thickness is 5cm. Multiple linearly arranged connecting holes 131 are formed on the connecting surface 13 of the mounting frame 1 to facilitate the passage of electrical wires. The mounting frame 1 is installed on the wall 102, with its second side facing inwards and its first side facing outwards, embedded within the wall 102.

[0040] The indicator background 2 is constructed as a rectangular plate, embedded in the receiving groove of the mounting frame 1 and connected to the second side. The surface of the indicator background 2 closest to the first side of the mounting frame 1 is printed with floor markings 103. Floor markings 103 are Arabic numerals, large in size, red in color, and have a black background. The surface area of ​​floor markings 103 is covered with a reflective film to improve contrast. Floor markings 103 are used in conjunction with the floor number displayed on the elevator floor indicator.

[0041] The dimming glass 3 is plate-shaped, embedded in the receiving groove of the mounting frame 1 and connected to the first side, and its shape is the same as that of the indicator background 2. In this embodiment, the dimming glass 3 is a polymer dispersed liquid crystal (PDLC) dimming glass 3, which is colorless and transparent when powered on, and fogged and light-blocking when not powered on. The dimming glass 3 is electrically connected to the elevator controller. When the elevator car arrives at the floor corresponding to the elevator floor display, the dimming glass 3 is powered on, so that the surface of the elevator floor display away from the wall 102 displays the floor mark 103.

[0042] In this embodiment, the elevator floor display also includes a lighting element 5, which is a light strip connected to the inner wall of the connecting surface 13 of the mounting frame 1, with the first and last ends connected to form a ring. When the dimming glass 3 is powered on and in a light-transmitting state, the lighting element 5 is turned on, thereby making the floor sign 103 more eye-catching.

[0043] Because the elevator floor display in this embodiment has a large surface area and is illuminated, the switching of the display state can be observed from a distance or the side, which helps prevent passengers from missing their ride.

[0044] In this embodiment, the indicator background 2, the dimming glass 3, and the lighting element 5 are all fixedly connected to the receiving groove by adhesive. In other embodiments, they can also be connected by other connection methods such as bolts.

[0045] Example 2: Please see Figure 3 The elevator floor display in this embodiment includes a mounting frame 1, an indicator background 2, a support plate 4, a dimming glass 3, and an illumination element 5. The indicator background 2 and the support plate 4 are embedded in the mounting frame 1. The support plate 4 has a partial cutout, and the dimming glass 3 is embedded in the cutout of the support plate 4.

[0046] In this embodiment, the structure of the mounting frame 1 is the same as in Embodiment 1, and the entire surface of the indicator background 2 near the first side of the mounting frame 1 is painted red. The support plate 4 is constructed as a light-shielding plate structure, embedded in the receiving groove of the mounting frame 1 and connected to the first side. Its surface away from the indicator background 2 is white, and its shape is the same as the indicator background 2. Sixteen hollow holes are formed in the middle of the mounting frame 1, and each hollow hole is filled with a PDLC dimming glass 3 of a matching shape, so that the hollow holes are completely closed. A total of 14 long strip-shaped dimming glass 3 form two parallel and adjacent seven-segment digital graphics, which are used to indicate the floor number. Above the seven-segment digital graphics, an upward indicator 104 and a downward indicator 105 are formed by dimming glass 3. Both are constructed as triangles and are set in different directions, respectively used to indicate whether the car is moving upward or downward. The 16 dimming glass 3 are electrically connected to the controller and operate independently. When different dimming glass 3 is powered on and becomes translucent, different red numbers are formed on the surface of the elevator floor display to indicate the floor corresponding to the car. The lighting element 5 is located between the indicator background 2 and the support plate 4, and turns on when the car arrives at the current floor to indicate that the car has arrived.

[0047] In this embodiment, the dimming glass 3 and the carrier plate 4 are bonded together with glass glue. In other embodiments, they can also be connected by a structure such as a plastic frame that faces the bidirectional opening and is structurally compatible.

[0048] Example 3: The only difference between this embodiment and embodiment two is that the elevator floor display in this embodiment is 0.1m long and 0.05m wide.

[0049] Example 4: The only difference between this embodiment and Embodiment 1 is that the elevator floor display in this embodiment is positioned opposite to the elevator door 101, with a vertical height of 0.8m and a bottom distance of 1.2m from the ground, making it easy for passengers inside and outside the car to observe.

[0050] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0051] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
