[0031] See also Figures 1 to 4 The present application provides an LCD module antenna device, the LCD module antenna device comprising:

[0032] Surface shell 1, circuit board assembly 2, TP-LCD cover plate 3 and antenna module 4;

[0033] The iron frame 5 of the TP-LCD cover plate 3 is provided with an antenna module 4;

[0034] The TP-LCD cover plate 3 is installed on one side of the face shell 1;

[0035] The circuit board assembly is installed on the other side of the housing 1 , and the circuit board assembly 2 is connected to the antenna module 4 .

[0036] The following describes in detail the various components in this embodiment:

[0037] Face shell 1: The face shell 1 connects the circuit board assembly 2 and the TP-LCD cover plate 3. The face shell 1 is mainly used to ensure the stability of various components inside the LCD module through the internal design structure and fixing form, and prevent the circuit board assembly 2, the TP-LCD cover plate 3 and the antenna module 4 inside the LCD module from loosening and displacement during use.

[0038] Circuit board assembly 2: The circuit board assembly 2 is installed on one side of the face shell 1 and connected to the antenna module 4. The circuit board assembly 2 is mainly used to receive signal data from the antenna module 4 and process the signal data, and then return the processed data signal to the antenna module 4.

[0039] TP-LCD cover 3: The TP-LCD cover 3 is fixed to the other side of the face shell 1, and an antenna module 4 is provided on the TP-LCD cover 3. The TP-LCD cover 3 is mainly used to carry the installation of the antenna module 4. Through the iron frame 5 provided on the inner side of the TP-LCD cover 3, the antenna module 4 can be stably fixed on the TP-LCD cover 3, thereby realizing the signal receiving and transmitting functions. In addition, the TP-LCD cover 3 is also responsible for converting the user's touch operation into an electrical signal, and transmitting it to the circuit board assembly 2 for processing through the antenna module 4.

[0040] Antenna module 4: Antenna module 4 is installed on the iron frame 5 set on the TP-LCD cover plate 3 and connected to the circuit board assembly 2. Antenna module 4 is mainly used for signal transmission and reception, responsible for transmitting the electrical signal on the TP-LCD cover plate 3 to the circuit board assembly 2 or receiving the signal of the external device to the circuit board assembly 2. In addition, it is also responsible for returning the signal processed by the circuit board assembly 2 to the TP-LCD cover plate 3, or transmitting the processed signal to the external device as needed.

[0041] Iron frame 5: The iron frame 5 is arranged on the inner side of the TP-LCD cover plate 3 and faces the fixed structure inside the face shell 1, and the antenna module 4 is arranged on the iron frame 5. The iron frame 5 mainly provides a stable frame protection for the TP-LCD cover plate 3 to prevent the TP-LCD cover plate 3 from being damaged due to external impact or vibration, and the antenna module 4 is integrated into the iron frame 5, which can also maximize the use of space and reduce the space occupied by the additional antenna module 4.

[0042] In actual application, when the LCD module needs to be assembled, the antenna module 4 set on the iron frame 5 set on the TP-LCD cover plate 3 is aligned with the preset position inside the face shell 1, and then the TP-LCD cover plate 3 is fixed on one side of the face shell 1, and then the circuit board assembly 2 is installed on the other side of the face shell 1. Further, the circuit board assembly 2 is connected to the antenna module 4 to complete the installation of the LCD module. When the LCD module is working, the user performs a touch operation through the TP-LCD cover plate 3, and then the TP-LCD cover plate 3 converts the touch operation into an electrical signal, and transmits the electrical signal to the antenna module 4 set on the iron frame 5. Then the antenna module 4 set in the iron frame 5 transmits the electrical signal to the circuit board assembly 2 connected thereto, and the circuit board assembly 2 receives the electrical signal and processes it. Further, the processed electrical signal will be transmitted back to the TP-LCD cover plate 3 through the antenna module 4 set in the iron frame 5, and fed back to the user through the TP-LCD cover plate 3. In addition, the antenna module 4 can also receive signals sent by external devices and pass the external signals to the circuit board assembly 2. The circuit board assembly 2 then processes the external signals and sends them to the external device through the antenna module 4 set in the iron frame 5, or the circuit board assembly 2 passes the signal data to the TP-LCD cover plate 3 through the antenna module 4, and the TP-LCD cover plate 3 processes the signal data and displays it to the user.

[0043] In this embodiment, the present application not only reduces the production cost, but also effectively avoids the expensive nano-injection molding process, and significantly improves the flexibility of antenna design by setting the antenna module 4 on the iron frame 5 and integrating it on the TP-LCD cover plate 3. In addition, once the position or shape of the antenna needs to be adjusted, only the iron frame 5 needs to be modified accordingly, and there is no need to make significant adjustments to the structure of the entire TP-LCD cover plate 3 or the LCD module, which simplifies the design process and effectively shortens the product production cycle.

[0044] In an optional embodiment, a face shell bracket 6 is disposed inside the face shell 1 , and the face shell bracket 6 and the face shell 1 are integrally formed.

[0045] In this embodiment, the face shell bracket 6 is arranged inside the face shell 1, and the face shell bracket 6 is mainly used to fix the TP-LCD cover plate 3 and the circuit board assembly 2 inside the LCD module. In the process of manufacturing the face shell 1 and the face shell bracket 6, an integrated molding setting is adopted, and the face shell bracket 6 is directly integrated into the face shell 1. In practical applications, the face shell 1 and the face shell bracket 6 are considered as an integral structure, which can ensure that the detailed processing and splicing of multiple components are avoided during the construction process, reduce the production cost, and reduce the difficulty of assembly. In addition, the design of the face shell 1 and the face shell bracket 6 being integrally molded also improves the overall stability of the LCD module, making it difficult for the face shell 1 and the face shell bracket 6 to loosen or deform, thereby effectively protecting the components installed inside.

[0046] In an optional embodiment, the inner side of the TP-LCD cover plate 3 is mounted on one side of the face shell bracket 6 by using glue dispensing or 3M glue.

[0047] In this embodiment, a method for installing the TP-LCD cover plate 3 and the face shell bracket 6 is provided, and the inner side of the TP-LCD cover plate 3 and one side of the face shell bracket 6 are installed by dispensing glue or 3M glue. In addition to the above installation methods, it can also be set according to actual conditions, which is not specifically limited here. In practical applications, the installation by dispensing glue is to place the inner side of the TP-LCD cover plate 3 at the corresponding position on one side of the face shell bracket 6, and then drip glue on the contact surface of the two by dispensing glue equipment, wherein the number and position of dispensing glue can be set according to the size and shape of the TP-LCD cover plate 3 and the structure of the face shell bracket 6, which is not specifically limited here. The installation by 3M glue is to paste the 3M glue on the inner side of the TP-LCD cover plate 3 or the corresponding position on one side of the face shell bracket 6, and then gently fit the two. Both installation methods can effectively reduce the difficulty and cost of installation, improve production efficiency, and ensure the close fit between the inner side of the TP-LCD cover plate 3 and the face shell bracket 6.

[0048] In an optional embodiment, the outer side of the TP-LCD cover plate 3 is flush with the face shell 1 .

[0049] In the present embodiment, a design is provided in which the outer side of the TP-LCD cover plate 3 is flush with the face shell 1. First, the size of the TP-LCD cover plate 3 is kept consistent with the opening size of the face shell 1, and then the TP-LCD cover plate 3 is installed on the face shell bracket 6. Then, the outer edge of the TP-LCD cover plate 3 is made to coincide with the edge of the face shell 1 through adjustment and alignment. Finally, the inner side of the TP-LCD cover plate 3 is firmly attached to the face shell bracket 6 by using glue or 3M glue, and it is ensured that it will not loosen or shift during use, thereby achieving the effect of the outer side of the TP-LCD cover plate 3 being flush with the face shell 1.

[0050] In actual applications, the design of the outer side of the TP-LCD cover plate 3 being flush with the face shell 1 makes the appearance of the LCD module more concise and smooth, and also enhances the user's tactile experience of the TP-LCD cover plate 3, and the flush surface reduces the discomfort of fingers during operation. In addition, the flush design also helps prevent external factors such as dust and water vapor from invading the gap between the TP-LCD cover plate 3 and the face shell 1, thereby increasing the overall service life of the LCD module.

[0051] In an optional embodiment, the antenna module 4 is integrally formed with the inner side of the TP-LCD cover plate 3 .

[0052] In this embodiment, when manufacturing the TP-LCD cover plate 3, the iron frame 5 provided on the inner side of the TP-LCD cover plate 3 is designed, and an antenna module 4 is designed in the iron frame 5, and then the antenna module 4 is integrated into the inner side of the TP-LCD cover plate 3, so that the antenna module 4 and the TP-LCD cover plate 3 become a whole. In practical applications, the antenna module 4 and the inner side of the TP-LCD cover plate 3 are an integrated structure, which simplifies the assembly process, reduces the production cost, and improves the connection stability and signal transmission efficiency between the antenna module 4 and the TP-LCD cover plate 3. In addition, this integrated design also avoids the problems of complex assembly, high production cost, and large antenna space occupation in the traditional assembly method.

[0053] In an optional embodiment, the circuit board assembly 2 includes a PCB board 7 and spring pins 8 , and the PCB board 7 is connected to the antenna module 4 via the spring pins 8 .

[0054] In this embodiment, a specific implementation of a circuit board assembly 2 is provided, and the circuit board assembly 2 includes a PCB board 7 and a spring pin 8. When the antenna module 4 receives signal data, the signal data is transmitted to the PCB board 7 through the spring pin 8, and then the PCB board 7 processes the signal data, and the further processed signal data is transmitted to the antenna module 4 through the spring pin 8, and finally the antenna module 4 sends the processed signal data to the external device or the TP-LCD cover 3.

[0055] In practical applications, the spring pin 8 is used to connect the PCB board 7 and the antenna module 4, and has a good signal transmission function. In the process of use, the elastic characteristics inside it can also resist external vibration and impact, ensuring the stability of the connection. As the center of signal data processing, the PCB board 7 can receive signal data from the antenna module 4 and process and analyze it quickly and accurately. The PCB board 7 feeds back the processed data to the antenna module 4 through the spring pin 8, realizing the information sharing and collaborative work between the PCB board 7 and the external device or the TP-LCD cover 3. Through the connection design of the spring pin 8 and the PCB board 7, the circuit layout is also optimized, the speed of information response is improved, and a smooth user experience is provided for the user.

[0056] In an optional embodiment, the spring pins 8 are mounted on the PCB board 7 by welding.

[0057] In this embodiment, a method for installing the spring pin 8 and the PCB board 7 is provided. The spring pin 8 and the PCB board 7 are installed by welding. In addition to the above installation methods, it can also be set according to actual conditions, which is not specifically limited here. In practical applications, the spring pin 8 is installed on the PCB board 7 by welding, which means that the spring pin 8 is placed on a preset welding position on the PCB board 7, and then the pin of the spring pin 8 and the pad on the PCB board 7 are heated by a welding device, so that the metal on the pin and the pad melts and fuses after heating, and a firm welding connection is formed after cooling, so that the spring pin 8 is stably welded on the PCB board 7. In practical applications, the spring pin 8 is installed on the PCB board 7 by welding, which can ensure the stability of the connection between the spring pin 8 and the PCB board 7 components, and also reduce the signal transmission problem caused by poor contact or looseness. In addition, the welding method is relatively simple and fast, which can greatly improve production efficiency.

[0058] In an optional embodiment, the PCB board 7 is provided with a mounting hole 9, and a mounting channel 10 is provided at a position corresponding to the mounting hole 9 on the face shell bracket 6. The PCB board 7 is installed on the other side of the face shell bracket 6 through a screw plug 11, and the screw plug 11 is set in the mounting hole 9 and the mounting channel 10.

[0059] In the present embodiment, a specific implementation process for installing the PCB board 7 is provided. First, the PCB board 7 is aligned above the face shell bracket 6 to ensure that the mounting hole 9 on the PCB board 7 is completely aligned with the corresponding mounting channel 10 on the face shell bracket 6. Next, the screw plug 11 is positioned correspondingly above the mounting hole 9 and the mounting channel 10. Further, the screw plug 11 is passed through the mounting hole 9 of the PCB board 7 and screwed into the mounting channel 10 until the screw plug 11 is tightened in place.

[0060] In practical applications, the stability of the installation is ensured by aligning the PCB board 7 with the mounting hole 9 and the mounting channel 10 of the housing bracket 6. The use of the screw plug 11 not only simplifies the installation steps, but also improves the firmness of the connection, effectively preventing the PCB board 7 from loosening or falling off during use. In addition, the method of installing the PCB board 7 by the screw plug also reduces the difficulty and cost of installation, effectively improving production efficiency.

[0061] In an optional embodiment, the antenna module 4 is provided with an antenna conductive area 12 , the antenna conductive area 12 is connected to the spring pin 8 , and the antenna conductive area 12 is mounted on the inner side of the TP-LCD cover plate 3 .

[0062] In this embodiment, a specific implementation method of the antenna conductive area 12 is provided. When an external signal is received by the antenna module 4, the signal will be transmitted to the spring pin 8 through the antenna conductive area 12 set by the antenna module 4, and then transmitted to the PCB board 7 by the spring pin 8 and processed. Then, the processed signal will be returned to the antenna conductive area 12 through the spring pin 8. Further, the antenna conductive area 12 returns the signal to the external device or transmits it to the TP-LCD cover through the antenna module 4.

[0063] In practical applications, the antenna conductive area 12 realizes the signal receiving and sending functions, effectively improving the communication capability between the antenna module 4 and the PCB board 7 and the TP-LCD cover 3. In addition, the connection between the antenna conductive area 12 and the spring pin 8 also effectively reduces the signal loss and interference during the transmission process, improves the communication quality, optimizes the communication process between the antenna module 4 and the PCB board 7 and the TP-LCD cover 3, enables the signal to be accurately transmitted between the components, and improves the performance of the LCD module.

[0064] In an optional embodiment, the antenna conductive area 12 and the inner side of the TP-LCD cover plate 3 are integrally formed.

[0065] In this embodiment, the antenna conduction area 12 and the inner side of the TP-LCD cover plate 3 are designed with an integrated structure. During the integrated setting design process, the antenna conduction area 12 will be designed for area size and quantity according to the needs of the antenna module 4, and then the designed antenna conduction area 12 will be integrated into the inner side of the TP-LCD cover plate 3. In practical applications, the integrated structure enhances the fixing strength between the antenna conduction part and the TP-LCD cover plate 3, and reduces the risk of loose connection or damage due to long-term use or external factors. Secondly, this setting optimizes the signal transmission path, reduces the loss and interference of the signal during the transmission process, improves the communication quality, and effectively utilizes the inner space of the TP-LCD cover plate 3.
