Description

Technical Field

[0001] This utility model relates to the field of display manufacturing, and in particular to a display. Background Technology

[0002] In-vehicle displays are increasingly used in modern automobiles, and these electronic devices are highly likely to encounter electrostatic discharge (ESD) problems during assembly. If ESD damages components, it will affect product yield and reliability, and may even damage the entire assembly. Therefore, effectively dissipating static electricity from various components during assembly and preventing ESD damage is a critical technical issue.

[0003] Current design solutions often use conductive adhesives, conductive foam, and wires to fix the metal casing, allowing static electricity to be discharged naturally during assembly. Alternatively, special circuit structures with automatic grounding paths can be designed to automatically form grounding paths during assembly. However, each component may carry a different static voltage. When multiple components are assembled simultaneously, these methods may result in unreliable dielectric connections, making it difficult to discharge accumulated static electricity synchronously and increasing the risk of electrostatic discharge damage. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a display that solves the problem that when multiple parts are assembled at the same time, the connection of the discharge medium is unreliable, which leads to the accumulation of static electricity that is difficult to discharge synchronously, increasing the risk of electrostatic discharge damage.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A display includes a liquid crystal display (LCD), a vehicle mounting bracket, a PCBA board, and a display back cover. One side of the vehicle mounting bracket is connected to a vehicle frame via a first conductive element. The side of the vehicle mounting bracket facing away from the first conductive element is connected to the PCBA board via a second conductive element. The side of the PCBA board facing away from the vehicle mounting bracket is connected to a screen bracket. A first exposed copper area is provided on the PCBA board, which abuts against the screen bracket. The side of the screen bracket facing away from the PCBA board is connected to the LCD via a third conductive element. A receiving cavity is provided inside the display back cover, and the LCD, the screen bracket, and the PCBA board are all disposed within the receiving cavity. The vehicle frame, the vehicle mounting bracket, the screen bracket, and the display back cover are all metal components.

[0006] Furthermore, the first conductive element, the second conductive element, and the third conductive element are screws.

[0007] Furthermore, the vehicle mounting bracket includes a support portion, a flat portion, and a fixing portion. The two opposite ends of the flat portion are bent downwards and connected to the support portion. The fixing portion is provided on the side of the flat portion facing away from the support portion. The support portion is detachably connected to the PCBA board through the second conductive component, and the fixing portion is detachably connected to the vehicle frame through the first conductive component.

[0008] Furthermore, a PCBA board connection hole adapted to the second conductive component is formed on the PCBA board, and a copper plating layer is provided on the inner wall of the PCBA board connection hole. A second exposed copper area is provided on the side of the PCBA board facing away from the screen bracket, and both the first exposed copper area and the second exposed copper area are connected to the copper plating layer.

[0009] Furthermore, the fixing part is provided with a fixing part connection hole adapted to the first conductive element, and the vehicle frame is provided with a vehicle frame connection hole adapted to the first conductive element.

[0010] Furthermore, the abutting part is provided with an abutting part connection hole adapted to the second conductive element.

[0011] Furthermore, the LCD screen is provided with an LCD screen connection hole adapted to the third conductive component, and the screen bracket is provided with a screen bracket connection hole adapted to the third conductive component.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: the vehicle mounting bracket is connected to the vehicle frame through a first conductive component, the vehicle mounting bracket is connected to the PCBA board through a second conductive component, the LCD screen is connected to the screen bracket through a third conductive component, and the screen bracket is in contact with the first exposed copper area on the PCBA board. All connections are made of metal materials. During the assembly process, each component can directly discharge static electricity onto the vehicle frame, avoiding the risk of static electricity accumulation and difficulty in synchronous discharge due to unreliable connection of the discharge medium during the production and assembly process, which increases the risk of electrostatic discharge damage.

[0019] Please see Figures 1 to 6 This utility model provides a display comprising an LCD screen 9, a vehicle mounting bracket 3, a PCBA board 5, and a display back cover 6. One side of the vehicle mounting bracket 3 is connected to a vehicle frame 1 via a first conductive element 2. The side of the vehicle mounting bracket 3 facing away from the first conductive element 2 is connected to the PCBA board 5 via a second conductive element 4. The side of the PCBA board 5 facing away from the vehicle mounting bracket 3 is connected to a screen bracket 8. A first exposed copper area 52 is provided on the PCBA board 5, and the first exposed copper area 52 abuts against the screen bracket 8. The side of the screen bracket 8 facing away from the PCBA board 5 is connected to the LCD screen 9 via a third conductive element 7. A receiving cavity 61 is provided inside the display back cover 6, and the LCD screen 9, the screen bracket 8, and the PCBA board 5 are all disposed within the receiving cavity 61. The vehicle frame 1, the vehicle mounting bracket 3, the screen bracket 8, and the display back cover 6 are all metal components.

[0020] The first conductive element 2, the second conductive element 4, and the third conductive element 7 are metal screws.

[0021] The first conductive component 2 can be a metal screw of model PWA5*16, the second conductive connector 4 can be a metal screw of model PM3*10, and the third conductive connector 7 can be a metal screw of model PM3*6, which is convenient for reinforcing the structure. At the same time, the metal screw can also be conductive, which is more conducive to the discharge of static electricity.

[0022] The rear cover 6 of the display has a receiving cavity 61, in which the liquid crystal screen 9, the screen bracket 8 and the PCBA board 5 are placed. It should be noted that the display screen 9 has a front and a back. The front refers to the side that displays the image, which is the side we usually look at, and the back refers to the side that is placed in the rear cover 6 of the display.

[0023] The vehicle mounting bracket 3 includes a support part 31, a flat part 32, and a fixing part 33. The two opposite ends of the flat part 32 are bent downwards and connected to the support part 31. The fixing part 33 is provided on the side of the flat part 32 facing away from the support part 31. The support part 31 is detachably connected to the PCBA board 5, and the fixing part 33 is detachably connected to the vehicle frame 1. The vehicle mounting bracket 3 needs to have a certain load-bearing capacity and durability, while also being lightweight and high-strength. Preferably, aluminum alloy material can be used.

[0024] The bending space formed between the flat plate portion 32 and the abutting portion 31 is used to accommodate electronic components on the PCBA board 5.

[0025] The PCBA board 5 has a PCBA board connection hole 51 adapted to the second conductive component 4. The inner wall of the PCBA board connection hole 51 is provided with a copper plating layer. The side of the PCBA board 5 facing away from the screen bracket 8 is provided with a second exposed copper area 53. Both the first exposed copper area 52 and the second exposed copper area 53 are connected to the copper plating layer. The exposed copper process of the PCBA board connection hole 51 can be solder paste printing, automatic solder paste application, or electroplated through hole. The appropriate process can be selected according to actual needs.

[0026] The fixing part 33 is provided with a fixing part connection hole 35 adapted to the first conductive element 2, and the vehicle frame 1 is provided with a vehicle frame connection hole 11 adapted to the first conductive element 2. The abutment part 31 is provided with an abutment part connection hole 34 that is adapted to the second conductive element 4.

[0027] The LCD screen 9 is provided with an LCD screen connection hole 91 adapted to the third conductive component 7, and the screen bracket 8 is provided with a screen bracket connection hole 81 adapted to the third conductive component 7.

[0028] Specifically, such as Figure 6 As shown, in this embodiment, the display is assembled first, and then connected to the vehicle frame 1 via the vehicle mounting bracket 3. Due to the above connection structure, when the display is installed, the third conductive component 7 is connected to the display screen 9 and fixed on the screen bracket 8. Furthermore, the second conductive component 4 fixes the PCBA board 5 to the vehicle mounting bracket 3. The first exposed copper area 52 on the PCBA board 5 is in direct contact with the screen bracket 8. Thus, the electrostatic conduction in the display is very smooth. Then, the display is installed on the vehicle frame 1 via the first conductive component 2. Since all contact parts are made of metal and are tightly fixed, the static electricity generated during the assembly of the components in the display will be smoothly conducted into the vehicle frame 1. This avoids the risk of electrostatic discharge damage caused by unreliable connection of the discharge medium during the production and assembly process, which may lead to static electricity accumulation and difficulty in synchronous discharge.

[0030] 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 this 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.
