[0031] For LCD displays, the stability of the connection between the electrical interface and the motherboard must be maintained during use to ensure the display can function properly in various environments. Currently, solid pins are generally used to improve the contact stability between the electrical interface and the motherboard. However, this stabilization method is limited in effectiveness and can easily cause the connection between the structures to accidentally disconnect due to external forces such as impact.

[0032] In view of this, an embodiment of the present invention provides an LCD display screen that can improve the stability of electrical connection and reduce the risk of poor contact or disconnection due to accidents during use. The interface module is connected to the mainboard, and then the reinforcing spring is placed on the interface module. The provided positioning part is used in conjunction with the mainboard to fix the interface module and improve the stability of the electrical connection.

[0033] In order to better understand the above technical solution, the above technical solution is described in detail below with reference to the accompanying drawings.

[0034] See also Figure 1 、 Figure 2 as well as Figure 3 , an LCD display screen proposed in an embodiment of the present utility model includes:

[0035] The display screen module 10 has a cavity inside and a through hole on one side;

[0036] The main board 20 is disposed in the cavity of the display module 10;

[0037] The interface module 30 is plugged into the mainboard 20, and the opening direction of the interface module 30 is arranged corresponding to the through hole; and

[0038] The reinforcing spring piece 40 is disposed on a side of the mainboard 20 facing the interface module 30 . A positioning portion 41 is provided on the reinforcing spring piece 40 . The positioning portion 41 is used to cooperate with the mainboard 20 to fix the interface module 30 on the mainboard 20 .

[0039] In the technical solution adopted in this embodiment, the display screen module 10 provides an integral structural frame 11 for the LCD display screen, ensuring structural strength. A cavity is formed within the display screen module 10, enabling the motherboard 20 and other components to be mounted within the cavity, thus providing protection for the motherboard 20. The motherboard 20 is a crucial component of the entire LCD display screen, capable of meeting the image display requirements of the LCD screen. The provided interface module 30 can be used to connect the motherboard 20 to external devices to transmit video, audio, and control signals. The provided reinforcing spring clip 40 can cooperate with the motherboard 20 to clamp the interface module 30 to the motherboard 20, strengthening the fixation between the interface module 30 and the motherboard 20 and thereby improving the stability of the electrical connection. Furthermore, by providing a positioning portion 41 on the reinforcing spring clip 40, the reliability of the fixation can be further enhanced. The technical solution proposed in this embodiment of the utility model, by providing the reinforcing spring clip 40 to secure the interface module 30, reduces the risk of accidental disconnection between the interface module 30 and the motherboard 20 due to external forces such as impact, thereby improving the stability of the electrical connection.

[0040] Specifically, the LCD display screen includes a display screen module 10 , a mainboard 20 , an interface module 30 and a reinforcing spring 40 .

[0041] The display screen module 10 converts the received signal into a visible image and is a key part for realizing the display function. It also provides the physical structural foundation of the LCD display screen and can provide support.

[0042] The mainboard 20 is disposed in the display screen module 10 and is responsible for receiving signals from external devices and processing the signals to adapt to the requirements of the display screen module 10 .

[0043] The interface module 30 is plugged into the main board 20 through solid pins to realize the connection between the main board 20 and the external device. The interface module 30 can be connected to the external device through a data cable. The design of the interface module 30 can be set according to different types of connecting cables, so that it can be compatible with a variety of different input devices or signal sources.

[0044] The reinforcing spring clip 40 is used to secure the interface module 30. It is understood that the reinforcing spring clip 40 provides additional fixation, ensuring that the connection between the interface module 30 and the motherboard 20 is not easily loosened when subjected to impact or vibration, thereby improving the stability of the connection. Furthermore, the reinforcing spring clip 40 is provided with a positioning portion 41, which may be a retaining ring. When the reinforcing spring clip 40 is attached to the motherboard 20, the retaining ring can be positioned around the perimeter of the interface module 30, further strengthening the fixation between the interface module 30 and the motherboard 20. This reduces the risk of poor electrical contact or disconnection between the interface module 30 and the motherboard 20 due to external forces such as impact or vibration during use. This improves the reliability of the reinforcing spring clip 40 in securing the interface module 30.

[0045] Further, refer to Figure 2 、 Figure 3 In one embodiment of the present invention, the surface of the reinforcing spring piece 40 that abuts against the mainboard 20 is adapted to the shape of the interface module 30 , and the middle area of ​​the reinforcing spring piece 40 protrudes at opposite ends to form a positioning portion 41 .

[0046] In the technical solution adopted in this embodiment, the surface of the reinforcing spring 40 that abuts the mainboard 20 is adapted to the outer shape of the interface module 30. This ensures precise alignment during installation and reduces the possibility of poor securing due to improper installation. In other words, this provides a better securing effect, increasing the mechanical strength of the entire connection structure and making it more stable. It can be understood that the adapted outer shape is the positioning portion 41 formed by the protrusions at the opposite ends of the central region of the reinforcing spring 40. This allows the interface module 30 to fit tightly with the mainboard 20, thereby optimizing signal transmission, reducing signal loss and interference, and improving the stability of the electrical connection.

[0047] Further, refer to Figure 1 In one embodiment of the present invention, the display screen module 10 includes a frame 11 and a display screen body 12 connected to each other. The frame 11 and the display screen body 12 cooperate to form a cavity, and a through hole is provided in the frame 11 .

[0048] In the technical solution adopted in this embodiment, the display screen module 10 may further include a frame 11 and a display screen main body 12. The frame 11 is the physical support structure of the display screen module 10, which can provide fixation and protection for the display screen main body 12 and other components. The frame 11 is usually made of metal or plastic material, which can protect the display screen main body 12 to reduce physical damage and ensure the stability and durability of the display screen main body 12. The display screen main body 12 is the core part of the display screen module 10 and is responsible for displaying images and text. In this embodiment, when the display screen main body 12 is installed on the frame 11, a cavity is formed between the display screen main body 12 and the frame 11, which can be used to install the main board 20 and other components. A through hole connected to the cavity is provided on the side of the frame 11 to facilitate the connection of the interface module 30 with external devices.

[0049] Further, refer to Figure 4 In one embodiment of the present invention, the LCD display further includes a positioning component 50 . The positioning component 50 is disposed on a side of the frame 11 facing the main board 20 and is used to position the main board 20 on the frame 11 .

[0050] In the technical solution adopted in this embodiment, the LCD display screen may further include a positioning assembly 50, which may be a positioning pin or a positioning column. The positioning pin or column can ensure a stable connection between the mainboard 20 and the frame 11, reducing displacement caused by external forces or vibrations, thereby further improving the stability of the electrical connection. Furthermore, the positioning pin or column can accurately position the mainboard 20 during installation, ensuring that the opening of the interface module 30 and the through-hole on the frame 11 maintain the correct corresponding position and connection during installation, reducing the risk of poor contact or accidental disconnection.

[0051] Further, refer to Figure 4 In one embodiment of the present invention, a positioning hole 21 is provided on the mainboard 20 , and the positioning assembly 50 includes a mounting position that can extend into the positioning hole 21 to position the mainboard 20 on the frame 11 .

[0052] In the technical solution adopted in this embodiment, the positioning assembly 50 may further include a mounting position. It is understood that when installing the mainboard 20, the positioning holes 21 on the mainboard 20 are aligned with the mounting positions, so that the mounting positions can pass through the positioning holes 21 to position the mainboard 20. Preferably, at least two mounting positions are provided, and each mounting position corresponds to a positioning hole 21.

[0053] Further, refer to Figure 2 、 Figure 3 In one embodiment of the present invention, a mounting hole 42 corresponding to the positioning hole 21 is provided on the reinforcing spring piece 40 , and the mounting position passes through the positioning hole 21 and is connected to the mounting hole 42 by screws.

[0054] In the technical solution adopted in this embodiment, by adopting such a configuration, the mounting position can be screwed to secure both the reinforcing spring 40 and the mainboard 20 to the frame 11 after passing through the positioning hole 21, thereby reducing the possibility of loosening. It is understood that the mounting position is provided with a threaded hole on the side facing away from the frame 11 for convenient connection.

[0055] Further, refer to Figure 2 、 Figure 3 In one embodiment of the present invention, three interface modules 30 are spaced apart along the width direction of the mainboard 20, and each interface module 30 is provided with a corresponding positioning portion 41. At least one mounting hole 42 is provided between the two positioning portions 41, and at least one mounting hole 42 is provided on the opposite side of the two positioning portions 41 near the two ends of the reinforcing spring piece 40.

[0056] In the technical solution adopted in this embodiment, three interface modules 30 are spaced apart along the width of the mainboard 20 to connect to external devices with different signals. The spacing facilitates the fixation of each interface module 30 and enhances the reliability of the fixation. The interface module 30 cooperates with the positioning portion 41 to provide better stability and reduce the risk of the interface module 30 shifting after being subjected to force, resulting in poor contact or disconnection between the mainboard 20. Specifically, at least one mounting hole 42 is provided between the two positioning portions 41. That is, when the two positioning portions 41 are respectively attached to the two interface modules 30, the portion between the two positioning portions 41 that contacts the mainboard 20 can be screwed to the mainboard 20 through the mounting hole 42. This can strengthen the connection between the portion of the reinforcing spring 40 between the two positioning portions 41 and the mainboard 20, thereby improving the stability and reliability of the overall structure. In addition, at least one mounting hole 42 is provided on the opposite side of the two positioning portions 41 near the two ends of the reinforcing spring 40 to enhance the connection between the end of the reinforcing spring 40 and the mainboard 20. It is understandable that, through the coordinated use of the positioning portion 41 and the mounting hole 42 , the anti-interference capability of the interface module 30 can be improved, and the influence of external forces on the connection between the interface module 30 and the mainboard 20 can be reduced.

[0057] Further, refer to Figure 2 In one embodiment of the present invention, the LCD display further includes a heat sink 60 , which is attached to the surface of the mainboard 20 and connected to the inner wall of the cavity of the display module 10 .

[0058] In the technical solution adopted in this embodiment, the heat sink 60 dissipates heat from the chips on the motherboard 20 and reinforces the motherboard 20, reducing the possibility of displacement during use. It will be appreciated that one end of the heat sink 60 is secured to the frame 11 via screws passing through the motherboard 20, while the other end is also secured to the frame 11, thereby limiting the space within the motherboard 20 and improving its stability.

[0059] Furthermore, in one embodiment of the present invention, heat dissipation silica gel is applied between the heat sink 60 and the mainboard 20 .

[0060] In the technical solution adopted in this embodiment, in order to further reduce the space between the heat sink 60 and the main board 20 and reduce the possibility of displacement of the main board 20, heat dissipation silicone can be applied between the heat sink 60 and the main board 20, which can improve stability and further enhance the heat dissipation effect.

[0061] Further, refer to Figure 1 In one embodiment of the present invention, the LCD display further includes a reinforcing pad 70 , which is disposed on a side of the display module 10 facing away from the main board 20 .

[0062] In the technical solution adopted in this embodiment, the reinforcing pad 70 can provide support and protection, reduce the risk of deformation or damage of the display screen module 10 when subjected to external force, and at the same time provide a certain buffering effect to improve the stability of the electrical connection.

[0063] The above description is merely an exemplary embodiment of the present invention and does not limit the patent scope of the present invention.
