[0060] This device is designed to allow the smart central control screen to better adapt to different series of switch panels in terms of size, and to follow the development progress of different series of switch panels, and flexibly launch smart central control screen products of the same series.
[0061] The utility model relates to an intelligent central control screen, which can control smart home devices through touch screen and voice control. The central control screen is divided into two parts, one part is the power base shell, which is installed in the traditional 86 bottom box. After installation, it is in the wall and invisible to the user; the other part is the central control part, which is connected to the power base shell and is attached to the wall after installation. It is the part that the user can operate. The utility model places the power supply and central control hardware in the power base shell through special hardware design and signal connection method, which can greatly reduce the thickness of the central control screen part, so that the intelligent central control screen can be adapted to the current ultra-thin switch panels. In order to adapt to switch panels of different styles, it is only necessary to replace the structure of the central control part, modularize the power supply, control part and touch screen part, and flexibly launch different series of intelligent central control screen products.
[0062] In a specific implementation of the present invention, the ultra-thin modular intelligent central control screen includes a touch screen part 1 and a bottom shell part 2. The entire product is constructed in a modular form, and touch screen parts 1 of different series can be replaced with each other.
[0063] The touch screen part 1 includes the touch screen 1-1, sensor board 1-2, antenna 1-3, back cover 1-4, middle frame 1-5, and speaker 1-6, which are the user interface and the part that needs to be exposed to the wall. The bottom shell part 2 includes the front cover 2-1, insulation board 2-2, bottom shell back cover 2-3, control board PCBA 2-4, power board PCBA 2-5, which build the power and control module of the product.
[0064] The touch screen part 1 and the bottom shell part 2 have a standardized data interface and connection method. Touch screen parts 1 of different series can be replaced with each other. The bottom shell part 2 can be adapted to the appearance of different series of products as a power supply and control module.
[0065] The middle frame 1-5 and the bottom shell back cover 2-3 are assembled together by snap fastening. Figure 2 As shown, the middle frame 1-5-1 and the bottom shell back cover 2-3-1 are fastened together through the middle frame buckle.
[0066] The touch screen part 1 includes a touch screen 1-1, a sensor board 1-2, an antenna 1-3, a back cover 1-4, a middle frame 1-5, and a speaker 1-6. In terms of hardware design, the touch screen 1-1 is embedded in the middle frame 1-5. As an embedded design, the touch screen 1-1 is integrated with the middle frame thickness. The thickness of the touch screen 1-1 is generally between 1.5 and 2mm, and the maximum thickness occupies 2mm of space. The sensor board 1-2 and the antenna 1-3 are embedded in the inner border of the middle frame 1-5. The width of the small board is integrated with part of the touch screen thickness and the middle frame thickness. The maximum width of the two small boards is 3mm. The speaker 1-6 is embedded in the structure of the middle frame 1-5, close to the touch screen 1-1, and has a maximum thickness of 2mm. The back cover 1-4 is embedded in the middle frame 1-5 and serves as the back cover of the touch screen part 1, with a maximum thickness of 1mm. According to Figure 3 As shown, the maximum thickness of the touch screen portion 1 is 5 mm.
[0067] The touch screen part 1 is connected to the bottom shell part 2 through FPC, RF cable and soft cable, and the bottom shell part 2 is connected to the above-mentioned FPC, RF cable and soft cable through the screen cable interface control board PCBA2-4-1, the sensor board cable interface control board PCBA2-4-2, the speaker interface control board PCBA2-4-3 and the RF interface control board PCBA2-4-4.
[0068] The thickness of FPC is less than 0.2mm, and the diameter of RF wire and soft wire is less than 0.8mm. Fig.12 As shown, the screen cable interface control board PCBA2-4-1, sensor board cable interface control board PCBA2-4-2, speaker interface control board PCBA2-4-3, and RF interface control board PCBA2-4-4 of the bottom shell part 2 are connected in a flexible and flexible manner to realize the transmission of screen data, microphone data, speaker data, wireless data, and sensor data. In addition, the FPC, RF line, and soft line can be pressed between the touch screen part 1 and the bottom shell part 2, which is convenient for installation and will not increase the thickness too much.
[0069] The bottom shell part 2 is composed of a front cover plate 2-1, an insulating plate 2-2, a bottom shell rear cover 2-3, a control board PCBA 2-4, and a power board PCBA 2-5. Fig. 9 As shown in the figure, install the power board PCBA 2-5, the insulation board 2-2, the control board PCBA 2-4 into the bottom shell back cover 2-3 in sequence, as shown in the figure. Fig.10 As shown, the pin headers in the control board PCBA 2-4 and the pin headers in the power board PCBA 2-5 and the pin headers in the power board PCBA 2-5-1 are connected together. Fig.11 As shown, the insulating plate 2-2 and the bottom shell back cover 2-3 are fixed by four buckles, forming a power supply and control part.
[0070] like Figure 6 As shown, there are two microphones and a proximity sensor on the sensor board 1-2, which are bent toward the front of the screen and the top of the middle frame respectively. The sensor faces the front of the screen to sense the approach of the human body, and the microphone pickup hole faces the top of the middle frame to obtain sound through the pickup hole on the top of the middle frame; Figure 7 The sensor board shown is then fixed on the middle frame through the sensor board fixing plate 1-7.
[0071] like Figure 8 As shown, by utilizing the gap between the middle frame and the screen, the antenna 1-3 is attached to the inner side of the middle frame 1-5 with double-sided tape, so that the antenna 1-3 is embedded in the middle frame 1-5, thereby compressing the hardware stacking thickness.
[0072] like Figure 8 As shown, the speaker 1-6 is pre-fixed in the groove designed in the middle frame 1-5 through the middle frame structure and double-sided tape, so that the speaker 1-6 is embedded in the middle frame 1-5 and close to the back of the touch screen, and the hardware stacking thickness is compressed as much as possible.
[0073] The installation process of this device is as follows:
[0074] The touch screen 1-1 is fixed on the middle frame 1-5 by dispensing glue, so that the touch screen 1-1 is embedded in the middle frame 1-5, achieving a thickness fusion effect.
[0075] Fix the sensor board 1-2 in the structural groove designed in the middle frame 1-5, and use the sensor board fixing plate 1-7 and screws to fix the middle frame 1-5, so that the sensor board is embedded in the central control.
[0076] Attach antenna 1-3 to the inner side of middle frame 1-5 with double-sided tape so that antenna 1-3 is embedded in the middle frame.
[0077] The speakers 1-6 are pre-fixed in the grooves designed in the middle frame 1-5 through the middle frame structure and double-sided tape, so that the speakers are embedded in the middle frame.
[0078] Pass the signal cables of the touch screen 1-1, the sensor board 1-2, the antenna 1-3, and the speaker 1-6 through the hollow part of the middle frame 1-5 and the perforation of the back cover 1-4.
[0079] Fix the back cover 1-4 to the middle frame 1-5 with screws, and the installation of the touch screen part 1 is completed.
[0080] Install the power board PCBA2-5, insulation board 2-2, and control board PCBA2-4 into the bottom shell back cover 2-3 in sequence, and connect the pin header of control board PCBA2-4-5 with the pin header of power board PCBA2-5-1 in power board PCBA2-5.
[0081] Pass the signal cables of the touch screen 1-1, sensor board 1-2, antenna 1-3, and speaker 1-6 through the holes on the top of the front cover 2-1, and connect them to the screen cable interface 2-4-1, sensor board cable interface 2-4-2, speaker interface 2-4-3, and RF interface 2-4-4.
[0082] The front cover 2-1 is connected with the bottom shell rear cover 2-3-1 of the bottom shell rear cover 2-3 through the middle frame buckle 1-5-1, fixing the power board PCBA2-5, the insulating board 2-2 and the control board PCBA2-4 placed in the bottom shell rear cover 2-3.
[0083] Finally, buckle the touch screen part 1 and the bottom shell part 2 together. Because the connecting line is a very thin soft cable and a very thin flexible field, it can be pressed between the touch screen part 1 and the bottom shell part 2 without affecting the overall thickness too much.
[0084] In actual use, the bottom shell part 2 is installed in the bottom box inside the wall. The thickness of the wall on the equipment is only the thickness of the touch screen part 1. Only the screen, sensor board (width), antenna (width), and speaker (thickness) are related to 1. The speaker (thickness) occupies the same thickness space as the sensor board (width) and antenna (width) in the central control, so the product thickness is only the thickness of the screen + speaker, thus achieving an ultra-thin effect.
[0085] Different series of products have different appearance styles. The main changes are the middle frame Sensor board 1-2. Because the screen size of the smart central control screen is standard size, the middle frame only needs to adapt to the Sensor board 1-2, antenna 1-3, and speaker 1-6. The power base and the two PCBAs in it do not need to be changed, so different series of products can be launched quickly.
[0086] The specific implementation scheme of this embodiment can refer to the relevant description in the above embodiment, which will not be repeated here.
[0087] It can be understood that the same or similar parts of the above embodiments can be referenced to each other, and the contents not described in detail in some embodiments can refer to the same or similar contents in other embodiments.

In addition, in the description of the present invention, unless otherwise specified, the meaning of "plurality" refers to at least two.

[0090] The ultra-thin modular intelligent central control screen device of the utility model can reduce the wall thickness of the central control screen to less than 5mm, and is suitable for ultra-thin switch panels and other switch panels on the market. It is widely applicable and has high versatility. The touch screen part is separated from the power supply and control part, and one type of bottom shell can be adapted to touch screens of different appearance styles, accelerating the development of diversified products.
