Description

Technical Field

[0001] The utility model relates to a telephone booth, in particular to an information display telephone booth. Background Art

[0002] With the continuous development of communication technology, people's demand for basic call functions of telephone booths has been declining year by year. Problems such as single function, inconvenient operation, outdated facilities and low utilization rate of telephone booths have become increasingly prominent. Telephone booths urgently need to undergo reasonable changes and transformations that meet the requirements of modern social development.

[0003] In the prior art, a phone booth is generally used as a device for providing city WiFi, or as a display of some information.

[0004] In the early days, the solution for using call booths as information display applications was generally light boxes. However, light boxes are not flexible enough, cannot display videos, and changing the display content is also relatively complicated. Therefore, some existing technologies use display screens instead of light boxes to bring richer displays.

[0005] However, the application of display screens will lead to more energy consumption, which is not conducive to the concept of green energy saving. Considering that advertisers do not place advertisements 24 hours a day, but videos or pictures need to be played when there are no advertisements, which undoubtedly leads to a waste of electricity. Utility Model Content

[0006] The purpose of the utility model is to provide an information display kiosk. By arranging a transparent display film on the surface of an electronic display screen and printing a first pattern on the transparent display film, the first pattern can be displayed even when the electronic display screen is turned off when the electronic display screen is not needed to play an advertising video, thereby saving electric energy.

[0007] The purpose of the utility model can be achieved through the following technical solutions:

[0008] An information display booth, comprising:

[0037] In conjunction with the accompanying drawings, some embodiments of the present invention are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0038] An information display booth, such as Figure 1 As shown, including:

[0039] A booth body 1 and at least one information display screen 2 arranged on a side of the booth body 1;

[0040] like Figure 2 As shown, the information display screen 2 includes an electronic display screen 21 and a transparent display film 22 attached to the surface of the electronic display screen 21, and a first pattern is printed on the transparent display film 22;

[0041] The electronic display screen 21 is a liquid crystal screen, a plasma screen or an OLED screen.

[0042] By arranging a transparent display film 22 on the surface of the electronic display screen 21 and printing the first pattern on the transparent display film 22, when the electronic display screen 21 is not needed to play the advertising video, the first pattern can still be displayed when the electronic display screen 21 is turned off, thereby saving power.

[0043] In some embodiments, the first pattern may be some public welfare pattern, so that when the electronic display screen 21 does not need to play advertisements, it can be used for public welfare publicity.

[0044] The information display screen 2 also includes a fill light. The fill light L1 is arranged toward the transparent display film 22. The fill light L1 can be arranged to fill light for the first pattern on the transparent display film 22 when no advertisement is played at night, thereby improving the effect.

[0045] In some embodiments, the fill light L1 is a light strip, which is arranged around the edge of the information display screen 2. Of course, in other embodiments, other arrangements may also be used.

[0046] The information display screen 2 also includes a light controller, which is connected to the electronic display screen 21 and the fill light L1 respectively. The function of the light controller is to control the fill light L1 to work according to the situation.

[0047] Generally, an ambient light sensor is also provided on the booth body 1, and the output end of the ambient light sensor is connected to the light controller. Based on the ambient light sensor, the fill light L1 is controlled not to light up during the day. Generally, the ambient light sensor is provided on the top of the booth body 1, so as to avoid interference from the fill light L1. In a certain embodiment, Figure 3 As shown, the ambient light sensor includes a photosensitive diode D1 and a first voltage-dividing resistor R1, one end of the first voltage-dividing resistor R1 is connected to the positive electrode of the first low-voltage DC power supply VCC1, and the other end is connected to the positive electrode of the photosensitive diode D1, and the negative electrode of the photosensitive diode D1 is connected to the negative electrode of the first low-voltage DC power supply VCC1; the positive electrode of the photosensitive diode D1 serves as the output end of the ambient light sensor, specifically, when it is daytime, the photosensitive diode D1 is in a conducting state, at this time, the output end of the ambient light sensor outputs a low level, on the contrary, when it is at night, the photosensitive diode D1 is in a disconnected state, at this time, the output end of the ambient light sensor outputs a high level.

[0048] like Figure 4 As shown, the lamp controller includes a main relay K1, a first sub-relay K2 and a temperature sensing switch. The coil of the main relay K1 and the contacts of the first sub-relay K2 are connected in series with the temperature sensing switch, and the contacts are connected to the fill light L1. Based on the temperature sensing switch, the electronic display screen 21 is sensed by temperature to see whether it is in a working state. There is no need for software linkage with the electronic display screen 21, and it has strong versatility and high reliability.

[0049] like Figure 5 The figure shows an implementation of a temperature sensing switch, which includes a second sub-relay K3, a second voltage-dividing resistor R4 and a temperature-sensitive resistor RT. After the second voltage-dividing resistor R4 and the temperature-sensitive resistor RT are connected in series, the other end of the second voltage-dividing resistor R4 is grounded, and the other end of the temperature-sensitive resistor RT is connected to the third DC power supply VCC3. The connection point between the second voltage-dividing resistor R4 and the temperature-sensitive resistor RT is connected to the coil of the second sub-relay K3. In this way, when the electronic display screen 21 is working, the temperature is high, the resistance of the temperature-sensitive resistor RT is low, and the second sub-relay K3 is in a natural state. Otherwise, the second sub-relay K3 is in an energized state. Combined with the ambient light sensor part, the output end of the ambient light sensor is connected to the coil of the first sub-relay K2 through an optical coupler T1. Therefore, the first sub-relay K2 is in a natural state during the day and in an energized state at night. When the first sub-relay K2 and the second sub-relay K3 are both in the energized state, the main relay K1 is energized and the fill light L1 is charged.

[0050] In addition, generally, in most embodiments, a heat insulation layer is provided between the fill light L1 and the electronic display screen 21 to reduce the influence of the fill light L1 on the temperature sensing switch. The temperature sensing switch is located on the electronic display screen 21, for example, at the side edge of the electronic display screen 21.
