Description

Technical Field

[0001] This utility model relates to the field of vehicle display technology, and in particular to a folding vehicle multimedia central control display screen. Background Technology

[0002] As a core component of modern automobiles, in-vehicle displays not only significantly improve the convenience of driving operations and road safety, but also comprehensively optimize the travel experience for drivers and passengers. With the continuous innovation of automotive electronics technology, in-vehicle displays have gradually evolved from early simple radio information display interfaces into intelligent interactive platforms integrating multiple functions, playing a crucial role in ensuring driving safety.

[0003] As the core display terminal of intelligent cockpit systems, in-vehicle displays are widely used in various application scenarios such as driver assistance systems, driving information display, navigation and positioning, and in-vehicle entertainment. However, current traditional in-vehicle displays generally adopt a centrally fixed, open installation scheme on the center console. Although this layout design takes into account both ease of operation and information visibility, the screen is exposed to the complex in-vehicle environment for a long time, which has the following prominent problems: First, the exposed state is prone to dust accumulation, and the screen may be scratched due to passengers' unintentional contact. This not only affects the visual presentation effect, but also shortens the service life of the equipment and reduces the overall aesthetics of the interior. Second, under strong sunlight, especially in the high temperature environment of summer, the temperature inside the car rises rapidly, and the display and its built-in electronic components will be subjected to high temperature stress continuously. This will accelerate the aging process of the components, leading to the degradation of display performance or even system failure, ultimately increasing the vehicle's maintenance costs and the frequency of component replacement.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items. Furthermore, the various embodiments of the invention, the features within those embodiments, and the features of the embodiments may be freely combined without obvious conflict or contradiction.

[0024] See Figures 1 to 3 A folding in-vehicle multimedia central control display screen includes a central control instrument panel 1 and a display component 2.

[0025] Specifically, the top of the central control instrument panel 1 is recessed to form a receiving groove 11, which is used to accommodate the display component 2. Two rotating shaft assemblies 3 are provided opposite to each other on the outer side walls of the receiving groove 11. The display component 2 is rotatably connected to the receiving groove 11 via the rotating shaft assemblies 3, so that after the display component 2 is closed, it forms an integral part with the central control instrument panel 1. The display component 2 is electrically connected to the vehicle's main unit. Multiple protrusions 111 are provided opposite to each other on the two side walls of the receiving groove 11. The protrusions 111 abut against the display component 2, so that the display component 2 is relatively fixed to the central control instrument panel 1. Two first through holes 112 are arranged opposite each other, and the positions of the first through holes 112 and the wire holes 241 are corresponding. The receiving groove 11 is provided with a second through hole 113 and a third through hole 114. The second through hole 113 is located on the side wall of the receiving groove 11. The movable rotating shaft 31 passes through the second through hole 113 and is connected to the rear cover 24 and the fixing plate 23. The sensor 4 is provided in the third through hole 114. The LCD display module 21 abuts against the top of the sensor 4. The sensor 4 is electrically connected to the vehicle host. The receiving groove 11 is provided with a recess 115 for accommodating fingers.

[0026] It should be noted that the structural design of the central control instrument panel 1 achieves a synergistic improvement in functionality and user experience through multi-dimensional optimization. Firstly, the recessed receiving groove 11 at the top and the cover-like design of the display component 2 eliminate the disjointed feel of traditional protruding screens, forming a unified, integrated panel that significantly enhances the interior aesthetics. Secondly, the dual-axis assembly 3 at the back, in conjunction with the abutment structure of the protrusion 111, provides the display component 2 with flexible opening and closing capabilities while ensuring a tight fixation in the closed state through the physical limitation of the protrusion 111, balancing usability and structural stability. Thirdly, the corresponding design of the positions of the first through hole 112 and the wiring hole 241 optimizes the wiring layout between the display component 2 and the vehicle's main unit, reducing the number of cables 26. Exposed and bending losses improve signal transmission reliability; fourthly, the movable pivot 31 of the second through hole 113 can assist the display component 2 in fine-tuning the angle. When the sensor 4 establishes physical contact with the liquid crystal display module 21, the liquid crystal display module 21 will turn off the display screen and maintain normal operation. This not only optimizes energy consumption but also ensures that the user experience is not affected. When the sensor 4 is not in contact with the liquid crystal display module 21, the liquid crystal display module 21 turns on the display. Combined with the recessed design of the recess 115 to accommodate fingers, it conforms to ergonomic operating habits and greatly improves the convenience and comfort of interaction. Under the synergistic effect of multiple structures, aesthetics, durability and intelligent interaction requirements are taken into account, effectively meeting the high experience requirements of in-vehicle scenarios.

[0027] Specifically, the display component 2 includes a liquid crystal display module 21, a circuit board 22, a fixing plate 23, and a rear cover 24. The liquid crystal display module 21 is fixed to one side of the fixing plate 23 by an adhesive layer 25. The circuit board 22 is fixed on the fixing plate 23 and the liquid crystal display module 21 is electrically connected to the circuit board 22. The side of the fixing plate 23 facing away from the liquid crystal display module 21 is snapped into the rear cover 24. The side wall of the rear cover 24 abuts against the protrusion 111. The fixing plate 23 is provided with a fixing groove 231 for fixing the circuit board 22. The bottom of the rear cover 24 is provided with two through holes 241 facing each other. The two through holes 241 correspond to the positions of the fixing groove 231. Cables 26 are provided in the through holes 241. The cables 26 are electrically connected to the circuit board 22 and the vehicle host respectively. A sealing strip is provided on the periphery of the rear cover 24.

[0028] It is worth mentioning that the LCD module 21 is fixed to the mounting plate 23 with an adhesive layer 25, which enhances the tightness of the fit and reduces the risk of the LCD module 21 falling off. The mounting plate 23 has a fixing groove 231 to accurately position the circuit board 22, avoid assembly misalignment, and improve electrical connection stability. The periphery of the mounting plate 23 has multiple snap-fit ​​slots 232, and the periphery of the rear cover 24 has multiple snap-fit ​​parts 242. The snap-fit ​​slots 232 and snap-fit ​​parts 242 are positioned correspondingly. The snap-fit ​​structure between the mounting plate 23 and the rear cover 24 simplifies the disassembly process, facilitates later maintenance or component replacement, and reduces maintenance costs. The wiring hole 241 at the bottom of the rear cover 24 is designed to optimize the internal wiring path and reduce cable bending losses. The sealing strip on the periphery of the rear cover 24 enhances the waterproof and dustproof performance, effectively preventing dust and moisture from entering the vehicle environment and protecting precision components such as the circuit board 22. With the synergistic effect of the multi-dimensional structure, assembly efficiency, usage stability, and durability are all taken into account, adapting to the complex working conditions of the vehicle environment.

[0029] Specifically, the rotating shaft assembly 3 includes a movable rotating shaft 31, a fixed bracket 32, a spring assembly 33, and a nut 34. The fixed bracket 32 ​​includes a connecting part 321 and a fixing part 322. The connecting part 321 is perpendicularly connected to the fixing part 322, and the fixing part 322 is fixedly connected to the central control instrument panel 1. The fixing part 322 is adjacent to the outer wall of the receiving groove 11. The connecting part 321 is provided with a shaft hole, which is interference-fitted to the movable rotating shaft 31. Both ends of the movable rotating shaft 31 protrude from the shaft hole, and one end of the movable rotating shaft 31 passes through the receiving groove. The sidewalls of the LCD module 21 and the rear cover 24 are connected to the fixing plate 23. A spring assembly 33 and a nut 34 are provided on the other end of the movable rotating shaft 31. The spring assembly 33 is sleeved on the movable rotating shaft 31, and both ends of the spring assembly 33 abut against the connecting part 321 and the nut 34, respectively. The fixing part 322 has multiple positioning holes, and stable installation and positioning are achieved through the rigid connection with the central control instrument panel 1 via the positioning holes. A finger is inserted into the recess 115 to clamp the upper and lower surfaces of the LCD module 21 and complete the flipping operation. During the flipping process, the fixing plate 23 drives the movable rotating shaft 31 to rotate synchronously. With the help of the friction between the spring assembly 33 and the connecting part 321 and the nut 34, the flipping angle of the LCD module 21 can be adjusted from 0° to 90°.

[0030] In scenarios where the display component 2 is not needed, this invention achieves automatic storage of the display component 2 through structural design. The display component 2 is housed in the receiving slot 11 of the central control instrument panel 1, which effectively prevents dust from adhering to the surface of the display component 2 and avoids the problem of accelerated aging of the display component 2 due to long-term exposure to sunlight, significantly improving the service life and protective performance of the display component 2. When the display component 2 needs to be used, the system can drive the connected display component 2 to adjust its angle through the built-in rotating shaft component 3, so that the display component 2 faces the driver's view, thereby providing the driver with a more convenient information viewing experience.
