Description

Technical Field

[0001] This invention relates to the field of display device technology, specifically to a method and device for displaying a smart cockpit for automobiles. Background Technology

[0002] With the development of automotive intelligence, in-vehicle displays have become a key component of automobiles. These displays include the central control screen, the passenger screen, and the rear passenger screen. The rear passenger screen is usually located on the roof or on the back of one row of seats. It is mainly used to play pictures, animations, videos, and video conferencing to enhance the entertainment and business convenience of rear passengers during their journey.

[0003] According to announcement number CN115923674A, an in-vehicle display device and a car are disclosed. The in-vehicle display device includes a folding mechanism and a display screen. The folding mechanism is mounted on the roof of the car in the front row space via its mounting bracket and is located between the headrests of the two front seats. The display screen is connected to the mounting bracket via a linkage assembly, wherein the linkage assembly includes a first link and a second link. The first link, the second link, the display screen and the mounting bracket form a four-bar linkage mechanism. Under the action of external force, the folding mechanism can fold or unfold the display screen.

[0004] However, in this in-vehicle display device and car, the back of the display screen is empty after it is unfolded. If the car is involved in a collision, the display screen may get caught on some object, making it impossible for the display screen to fold, which may cause injury to the front passengers and the driver. Therefore, a smart cockpit display method and device for automobiles is proposed to solve the above problems. Summary of the Invention

It has the advantage of preventing objects from being caught in the display screen, thus solving the problem that in the in-vehicle display device and automobile, the back of the display screen is empty after it is unfolded. If a collision occurs, the display screen may easily catch an object, preventing it from folding and potentially causing injury to passengers and the driver.

[0007] (II) Technical Solution

[0008] To achieve the aforementioned purpose of preventing objects from being trapped by the display screen, the present invention provides the following technical solution: an automotive intelligent cockpit display device, comprising a housing, a folding mechanism disposed inside the housing, a dustproof mechanism disposed inside the housing, and a rotating mechanism disposed inside the housing;

[0009] The folding mechanism includes a first folding shell, the front and rear sides of which are rotatably connected to the front and rear side walls of the inner cavity of the outer shell. A second folding shell is rotatably mounted between the front and rear side walls of the inner cavity of the first folding shell. A third folding shell is rotatably mounted between the front and rear side walls of the inner cavity of the second folding shell. A fourth folding shell is rotatably mounted between the front and rear side walls of the inner cavity of the third folding shell. A fifth folding shell is rotatably mounted between the front and rear side walls of the inner cavity of the fourth folding shell. A display screen is fixedly mounted on the left side of the fifth folding shell. A first motor is fixedly mounted on the inner top wall of the outer shell. The output shaft of the first motor is fixedly connected to a U-shaped rod with one end penetrating through and extending to the outside of the outer shell via a coupling. The front and rear side walls of the inner cavity of the U-shaped rod are respectively fixedly connected to the front and rear side walls of the display screen.

[0010] Furthermore, the dustproof mechanism includes a second motor, the right side of which is fixedly connected to the right side wall of the inner cavity of the housing, and the output shaft of the second motor is fixedly connected to two rotating shafts through a coupling, with a transverse bevel gear fixedly installed on the outer surface of each of the two rotating shafts.

[0011] Furthermore, the rotating mechanism includes a housing located inside the outer shell. A third motor is fixedly installed on the left side wall of the inner cavity of the housing. The output shaft of the third motor is fixedly connected to a movable shaft with one end penetrating through and extending to the outside of the outer shell via a coupling. An mounting plate is fixedly installed on the top of the movable shaft.

[0012] Furthermore, a groove is provided on the right side wall of the inner cavity of the second folding shell, and a slider is fixedly installed on the right side of the third folding shell, with the inner surface of the groove slidably connected to the outer surface of the slider.

[0013] Furthermore, the first folded shell, the second folded shell, the third folded shell, the fourth folded shell, and the fifth folded shell are nested together.

[0014] Furthermore, two threaded rods are rotatably mounted on the left side wall of the inner cavity of the outer shell, and vertical bevel gears are fixedly mounted on the outer surfaces of the two threaded rods, with the outer surfaces of the two vertical bevel gears meshing with the outer surfaces of the two horizontal bevel gears respectively.

[0015] Furthermore, each of the two threaded rods has a threaded block threaded onto its outer surface, with one end penetrating through and extending to the outside of the housing, and a dust cover is fixedly installed on the opposite side of the two threaded blocks.

[0016] Furthermore, the inner cavity of the outer shell is provided with movable grooves on both the front and rear side walls, and the inner surfaces of the two movable grooves are slidably connected to the outer surfaces of the two threaded blocks respectively.

[0017] Furthermore, the inner bottom wall of the cabin is provided with a movable hole, and the inner surface of the movable hole is rotatably connected to the outer surface of the movable shaft.

[0018] Another technical problem to be solved by the present invention is to provide a method for displaying an intelligent cockpit in an automobile, comprising the following steps:

[0019] 1) Sensors receive signals. Automotive sensors can be divided into front sensors, central sensors, and safety sensors according to different tasks. Front sensors are used to detect signals of low-speed frontal collisions, central sensors are used to detect signals of high-speed collisions, and safety sensors are used to prevent the system from malfunctioning in non-collision situations.

[0020] 4) Signal processing and judgment: The sensor transmits the received collision signal to the central controller. The central controller analyzes and judges these signals. If the measured acceleration, velocity change or other indicators exceed the predetermined value, the central controller will drive the display screen to fold.

[0021] 5) The display screen folds, the first motor is started, and the rotating shaft and the display screen rotate counterclockwise. The display screen drives the fifth folding shell, the fourth folding shell, the third folding shell, the second folding shell and the first folding shell to fold through the slider, so that the display screen is retracted into the shell.

[0022] 4) With the dust cover on, start the second motor to drive the two rotating shafts and two horizontal bevel gears to rotate. The two horizontal bevel gears drive the two threaded rods to rotate, and the two threaded rods drive the two threaded blocks and a dust cover to move to the right, so that the dust cover covers the outer shell to prevent the display screen from being ejected by a collision.

Detailed Implementation

[0033] The technical solutions of the present invention will be clearly and completely described below with reference to the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Please see Figure 1-5 A smart cockpit display device for automobiles includes a housing 1, a folding mechanism 2 and a dustproof mechanism 3 inside the housing 1, and a rotating mechanism 4 inside the housing 1.

A display screen 206 is fixedly installed on the left side of the fifth folding shell 205. A first motor 207 is fixedly installed on the inner top wall of the outer shell 1. The output shaft of the first motor 207 is fixedly connected to a U-shaped rod 208 with one end penetrating through and extending to the outside of the outer shell 1 through a coupling. The front and rear side walls of the inner cavity of the U-shaped rod 208 are fixedly connected to the front and rear sides of the display screen 206, respectively.

[0036] The second folding shell 202 has a groove 209 on the right side wall of its inner cavity, and a slider 210 is fixedly installed on the right side of the third folding shell 203. The inner surface of the groove 209 is slidably connected to the outer surface of the slider 210. The first folding shell 201, the second folding shell 202, the third folding shell 203, the fourth folding shell 204 and the fifth folding shell 205 are nested together.

[0037] Specifically, the first motor 207 is started, which drives the rotating shaft 302 and the display screen 206 to rotate, causing the display screen 206 to rotate clockwise. The display screen 206 drives the fifth folding shell 205, the fourth folding shell 204, the third folding shell 203, the second folding shell 202 and the first folding shell 201 to unfold via the slider 210. The folding shells close the right side of the display screen 206 to prevent the display screen 206 from getting caught on an object when it closes in the event of a car collision, which would prevent the display screen 206 from folding and could easily cause injury to passengers and the driver.

The output shaft of the second motor 301 is fixedly connected to two rotating shafts 302 through a coupling. A transverse bevel gear 303 is fixedly installed on the outer surface of each of the two rotating shafts 302.

[0039] Two threaded rods 304 are rotatably mounted on the left side wall of the inner cavity of the outer shell 1. Vertical bevel gears 305 are fixedly mounted on the outer surfaces of the two threaded rods 304. The outer surfaces of the two vertical bevel gears 305 mesh with the outer surfaces of the two horizontal bevel gears 303 respectively. A threaded block 306 with one end penetrating through and extending to the outside of the outer shell 1 is threadedly mounted on the outer surface of the two threaded rods 304. A dust cover 307 is fixedly mounted on the opposite side of the two threaded blocks 306. Movable grooves are opened on the front and rear side walls of the inner cavity of the outer shell 1. The inner surfaces of the two movable grooves are slidably connected to the outer surfaces of the two threaded blocks 306 respectively.

[0040] Specifically, the second motor 301 is started, which drives the two rotating shafts 302 and the two horizontal bevel gears 303 to rotate. The two horizontal bevel gears 303 drive the two threaded rods 304 to rotate. The two threaded rods 304 drive the two threaded blocks 306 and a dust cover 307 to move to the left, so that the bottom of the outer casing 1 is exposed. The dust cover 307 protects the display screen 206 and reduces the contact between the display screen 206 and the outside world.

[0041] In this embodiment, the rotating mechanism 4 includes a housing 401 located inside the outer shell 1. A third motor 402 is fixedly installed on the left side wall of the inner cavity of the housing 401. The output shaft of the third motor 402 is fixedly connected to a movable shaft 403 with one end penetrating through and extending to the outside of the outer shell 1 via a coupling.

[0042] Specifically, starting the third motor 402 drives the movable shaft 403 to rotate, so that the movable shaft 403 can adjust the angle of the display screen 206 through the mounting plate 404, which can be adjusted according to the user's viewing angle, making it more convenient for the user.

[0043] Another technical problem to be solved by the present invention is to provide a method for displaying an intelligent cockpit in an automobile, comprising the following steps:

[0044] 1) Sensors receive signals. Automotive sensors can be divided into front sensors, central sensors, and safety sensors according to different tasks. Front sensors are used to detect signals of low-speed frontal collisions, central sensors are used to detect signals of high-speed collisions, and safety sensors are used to prevent the system from malfunctioning in non-collision situations.

[0045] 6) Signal processing and judgment: The sensor transmits the received collision signal to the central controller. The central controller analyzes and judges these signals. If the measured acceleration, velocity change or other indicators exceed the predetermined value, the central controller will drive the display screen to fold.

[0046] 7) The display screen folds, the first motor is started, and the rotating shaft and the display screen rotate counterclockwise. The display screen drives the fifth folding shell, the fourth folding shell, the third folding shell, the second folding shell and the first folding shell to fold through the slider, so that the display screen is retracted into the shell.

[0047] 4) With the dust cover on, start the second motor to drive the two rotating shafts and two horizontal bevel gears to rotate. The two horizontal bevel gears drive the two threaded rods to rotate, and the two threaded rods drive the two threaded blocks and a dust cover to move to the right, so that the dust cover covers the outer shell to prevent the display screen from being ejected by a collision.

[0048] This method ensures that the car's smart cockpit display will not become unfoldable due to accidents, thus preventing injury to passengers and drivers.

[0049] The working principle of the above embodiments is as follows:

[0050] (1) Fix the mounting plate 404 to the inner top wall of the car's intelligent cockpit. When the display screen 206 is in use, start the second motor 301 to drive the two rotating shafts 302 and the two horizontal bevel gears 303 to rotate. The two horizontal bevel gears 303 drive the two threaded rods 304 to rotate. The two threaded rods 304 drive the two threaded blocks 306 and a dust cover 307 to move to the left, so that the bottom of the outer shell 1 is exposed.

[0051] (2) Start the first motor 207, drive the rotating shaft 302 and the display screen 206 to rotate, so that the display screen 206 rotates clockwise. The display screen 206 drives the fifth folding shell 205, the fourth folding shell 204, the third folding shell 203, the second folding shell 202 and the first folding shell 201 to unfold through the slider 210, and the folding shells close the right side of the display screen 206.
