Description

Technical Field

[0001] This utility model relates to the field of liquid crystal displays, and in particular to a narrow-bezel automotive liquid crystal display. Background Technology

[0002] In-vehicle LCD screens are a common type of electronic display device in modern cars, widely used in various fields such as vehicle dashboards, navigation systems, and entertainment information systems.

[0003] In-vehicle LCD displays are used in train carriages and control areas. With bezels ≤5mm wide, their narrow bezel design reduces space occupation in the train's passenger compartment. However, when using narrow-bezel LCD displays on trains, the displays rely on the bezel for natural heat dissipation. The narrow bezel design reduces the heat dissipation area. In summer, when the air conditioning ducts in the train passenger compartment are unevenly distributed, the display's operating power can be ≥20W, causing localized increases in panel temperature. The inability to dissipate heat quickly can accelerate the aging of the LCD panel driver chip, thus affecting the display's performance. Utility Model Content

[0004] The technical problem this utility model aims to solve is: when using a narrow-bezel in-vehicle LCD display on a train, the LCD display relies on the bezel for natural heat dissipation. The narrow bezel design reduces the heat dissipation area. When the air conditioning ducts in the train passenger compartment are unevenly covered in summer, the display's operating power is ≥20W, and the local temperature of the panel is prone to increase. The heat cannot be dissipated quickly, which will accelerate the aging of the LCD panel driver chip, thus affecting the performance of the in-vehicle LCD display.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a narrow bezel vehicle LCD display screen, including a frame, a display screen body on one side of the frame, and a heat dissipation device on one side of the frame, wherein the heat dissipation device dissipates heat from the frame and the display screen body through heat dissipation fins.

[0006] Preferably, the heat dissipation device includes a mounting block, bolts, a placement plate, several heat dissipation fins, and a ventilation component. The mounting block is disposed on one side of the frame, and the bolts are inserted into the mounting block to connect with the placement plate. Several heat dissipation fins are disposed on one side of the placement plate to dissipate heat. The ventilation component is disposed on the side of the frame near the heat dissipation fins to ventilate the heat dissipation fins.

[0007] Preferably, the ventilation assembly includes a fan, a connecting pipe, and several ventilation pipes. The fan is located on one side of the frame, one side of the connecting pipe is connected to the fan, and several ventilation pipes are located on both sides of the connecting pipe for ventilation.

[0008] Preferably, an auxiliary block is provided on the side of the ventilation pipe away from the connecting pipe, and the auxiliary block on the side away from the ventilation pipe is smaller in size.

[0009] Preferably, the outlet of the ventilation duct is close to the heat dissipation fins to increase the airflow speed on the surface of the heat dissipation fins.

[0010] Preferably, the placement plate is provided with support components on both sides to support the two sides of the connecting pipe.

[0011] Preferably, the support component includes support blocks disposed on both sides of the placement plate and supporting the connecting pipe.

[0012] Preferably, guide plates are inclined on both sides of the support block, and the guide plates increase the size of the entrance of the support block.

[0013] Preferably, the placement plate is provided with a flow guiding component near the heat dissipation fins. The flow guiding component includes a flow guiding block and an extension plate. The flow guiding block is disposed on the placement plate near the gap between the two heat dissipation fins, and the placement plate is triangular on the side near the auxiliary block. An extension plate is provided on one side of the flow guiding block to form an air duct with one of the heat dissipation fins.

[0014] In summary, the beneficial effects of this utility model are as follows:

[0015] By using a heat dissipation device, the frame can be quickly cooled, preventing the display body from overheating and causing accelerated aging of the LCD panel driver chip. This extends the lifespan of the vehicle LCD display and improves its performance.

Detailed Implementation

[0024] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0025] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" or "linked" should be interpreted broadly. For example, it can refer to a fixed connection, a detachable connection, or an integral connection; it can refer to a mechanical connection or an electrical connection; it can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0026] Figures 1 to 5 The illustrated narrow-bezel in-vehicle LCD display includes a frame 1, a display body 2 on one side of the frame 1, and a heat dissipation device 3 on the other side of the frame 1. The heat dissipation device 3 uses heat dissipation fins 34 to dissipate heat from the frame 1 and the display body 2. The in-vehicle LCD display will be used in the carriage and control area. The frame 1 has a width of ≤5mm. The narrow bezel design reduces the space occupied in the train passenger compartment aisle. After installation, the display is shown on the display body 2 on the frame 1, and the heat dissipation device 3 is used to quickly dissipate heat from the frame 1.

[0027] Figures 1 to 5 The heat dissipation device 3 shown includes a mounting block 31, bolts 32, a placement plate 33, several heat dissipation fins 34, and a ventilation component 35. The mounting block 31 is located on one side of the frame 1, and the bolts 32 are inserted into the mounting block 31 to connect with the placement plate 33. Several heat dissipation fins 34 are located on one side of the placement plate 33 to dissipate heat. The ventilation component 35 is located on the side of the frame 1 near the heat dissipation fins 34 to ventilate the heat dissipation fins 34.

[0028] Figures 1 to 5As shown, when using the heat dissipation device 3, the placement plate 33 is moved to contact the mounting block 31 fixed on the surface of the frame 1. Then, the bolt 32 is rotated to thread the bolt through the mounting block 31 and the placement plate 33, thus fixing the position of the placement plate 33. Several heat dissipation fins 34 fixed on the surface of the placement plate 33 dissipate the heat generated inside the frame 1. The ventilation component 35 fixed on the side of the frame 1 near the heat dissipation fins 34 accelerates the airflow at the heat dissipation fins 34, allowing the heat dissipation fins 34 to better dissipate heat. By using the heat dissipation device 3, the frame 1 can be quickly cooled, preventing the temperature of the display body 2 from rising too much, which could accelerate the aging of the LCD panel driver chip, thereby extending the service life of the vehicle LCD display and improving the performance of the vehicle LCD display.

[0029] Figures 1 to 5 The ventilation assembly 35 shown includes a fan 351, a connecting pipe 352, and several ventilation pipes 353. The fan 351 is located on one side of the frame 1, and the connecting pipe 352 is connected to the fan 351 on one side. Several ventilation pipes 353 are located on both sides of the connecting pipe 352 for ventilation. By activating the fan 351 fixed on one side of the frame 1, air reaches the inside of the connecting pipe 352, then the air is sent into the ventilation pipes 353, and finally the air is discharged from the ventilation pipes 353, which accelerates the airflow at the heat dissipation fins 34, allowing the heat dissipation fins 34 to better dissipate the heat generated inside the frame 1.

[0030] Figures 1 to 5 An auxiliary block 354 is provided on the side of the ventilation duct 353 away from the connecting pipe 352. The auxiliary block 354 is smaller on the side away from the ventilation duct 353. By fixing the auxiliary block 354 to one side of the ventilation duct 353, and by making the side of the auxiliary block 354 away from the ventilation duct 353 smaller, the air exhaust speed is increased, thereby increasing the airflow speed at the heat dissipation fins 34, thus improving the performance of the ventilation duct 353. The outlet of the ventilation duct 353 is close to the heat dissipation fins 34, increasing the airflow speed on the surface of the heat dissipation fins 34. By placing the outlet of the ventilation duct 353 close to the heat dissipation fins 34, the air near the surface of the heat dissipation fins 34 circulates better, thereby improving the performance of the heat dissipation fins 34.

[0031] Figures 1 to 5The placement plate 33 shown has support components 36 on both sides to support the connecting pipe 352. Each support component 36 includes a support block 361, which is disposed on both sides of the placement plate 33 and supports the connecting pipe 352. When the connecting pipe 352 is fixed to the placement plate 33 by the support blocks 361, it is supported by the support blocks 361, making the connecting pipe 352 more stable for use. Guide plates 362 are inclinedly provided on both sides of the support blocks 361, raising the size of the inlet of the support blocks 361. By fixing the guide plates 362 inclinedly on both sides of the support blocks 361, the size of the inlet of the support blocks 361 is raised, making it easier for the connecting pipe 352 to contact the support blocks 361.

[0032] Figures 1 to 5 The placement plate 33 shown is provided with a flow guiding component 37 near the heat dissipation fins 34. The flow guiding component 37 includes a flow guiding block 371 and an extension plate 372. The flow guiding block 371 is located on the placement plate 33 near the gap between the two heat dissipation fins 34, and the placement plate 33 is triangular on the side near the auxiliary block 354. An extension plate 372 is provided on one side of the flow guiding block 371 to form an air duct with one of the heat dissipation fins 34. When the air is discharged from the auxiliary block 354, the triangular flow guiding block 371 on the side near the auxiliary block 354 separates and guides the air. The air is then dispersed to the side where the two heat dissipation fins 34 are close to each other, so that a large amount of air can also pass through the heat dissipation fins 34 on the side away from the ventilation pipe 353. The extension plate 372 and the heat dissipation fins 34 form an air duct, allowing the air to move quickly along one side of the heat dissipation fins 34.

[0033] Working principle: The vehicle-mounted LCD screen will be used in the carriage and control area. The width of the frame 1 is ≤5mm. With the narrow bezel design, it can reduce the space occupied in the passenger compartment of the train. After installation, the screen body 2 on the frame 1 will display the picture. The heat dissipation device 3 is used to quickly dissipate heat from the frame 1. When using the heat dissipation device 3, move the placement plate 33 so that it contacts the mounting block 31 fixed on the surface of the frame 1. Then, rotate the bolt 32 so that the bolt 32 passes through the mounting block 31 and is threadedly fixed to the placement plate 33. Then, the position of the placement plate 33 is fixed. Then, several heat dissipation fins 34 fixed on the surface of the placement plate 33 dissipate the heat generated inside the frame 1. The ventilation component 35 fixed on the side of the frame 1 near the heat dissipation fins 34 accelerates the airflow at the heat dissipation fins 34, so that the heat dissipation fins 34 can better dissipate heat. By using the heat dissipation device 3, the frame 1 can be quickly cooled, avoiding excessive temperature rise of the display body 2, which would accelerate the aging of the LCD panel driver chip, thereby extending the service life of the vehicle LCD display and improving the performance of the vehicle LCD display.
