Detailed implementation manner

[0031] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0032] An intelligent cockpit stretchable vehicle-mounted display device, as Figures 1-4 shown, includes a display screen 1, a connection frame 2, a mounting strip 3, an angle adjustment mechanism and a stretching mechanism. The connection frame 2 is connected to the rear side of the display screen 1, the mounting strip 3 is installed in the middle of the rear side of the display screen 1, the angle adjustment mechanism is provided on the mounting strip 3, the angle adjustment mechanism is used to adjust the angle of the display screen 1, and the stretching mechanism is provided on the connection frame 2.

[0033] As Figures 2-4 shown, the angle adjustment mechanism includes a connection seat 41, an adjustment motor 42 and a sliding seat 43. There are two connection seats 41. One of the connection seats 41 is hinged to the upper part of the mounting strip 3, the other connection seat 41 is connected with a sliding seat 43, the sliding seat 43 is slidably connected to the lower part of the mounting strip 3, and adjustment motors 42 are installed on the tops of the two connection seats 41.

[0034] As Figures 2-4As shown in the figure, the stretching mechanism includes a mounting plate 51, a base 52, a connecting rod 53, and a stretching motor 54. A mounting plate 51 is installed in the middle of the connecting frame 2. Bases 52 are installed on both the upper and lower sides of the mounting plate 51. There are two sets of connecting rods 53, with three connecting rods 53 in each set. Two of the connecting rods 53 are short connecting rods 53, and the other connecting rod 53 is a long connecting rod 53. The two short connecting rods 53 are respectively hinged to the two ends of the long connecting rod 53. One of the short connecting rods 53 is hinged to the base 52, and the other connecting rod 53 is hinged to the connecting seat 41. A stretching motor 54 is installed at the hinge between the short connecting rod 53 and the long connecting rod 53 and on the base 52. The output shaft of the stretching motor 54 is connected to the connecting rod 53, so that the operation of the stretching motor 54 can drive the connecting rod 53 to swing, thereby squeezing the connecting seat 41 through the connecting rod 53 to push out the display screen 1, achieving the effect of driving the display screen 1 to extend. The output shaft of the adjustment motor 42 is connected to the connecting rod 53, so that when the adjustment motor 42 operates, since the output shaft of the adjustment motor 42 is fixed, the body of the adjustment motor 42 can rotate, thereby driving the connecting seat 41, the mounting strip 3, and the display screen 1 to rotate, so as to adjust the display angle of the display screen 1.

[0035] When the in-vehicle display screen 1 needs to be used, this in-vehicle display device can be used to display the required information through the display screen 1. During the use process, if it is necessary to extend the display screen 1 for the passengers to watch, the three stretching motors 54 can be controlled to operate. When the stretching motors 54 operate, they drive the connecting rods 53 to swing, causing the display screen 1 to extend forward, so that the display screen 1 extends out, making the display screen 1 closer to the user for easy viewing. When it is necessary to adjust the left and right angles of the display screen 1, the adjustment motor 42 can be controlled to operate. When the adjustment motor 42 operates, since the output shaft of the adjustment motor 42 is fixedly connected to the connecting rod 53 and the connecting rod 53 is fixedly arranged, only the body of the adjustment motor 42 can be driven to rotate. When the body of the adjustment motor 42 rotates, it will drive the display screen 1 to rotate through the connecting seat 41 and the mounting strip 3, so as to adjust the left and right angles of the display screen 1 for users in different positions to watch and use. When it is necessary to adjust the up and down angles of the display screen 1, the lower part of the display screen 1 can be directly pulled back and forth. When the lower part of the display screen 1 moves, it will drive the mounting strip 3 to move. At this time, the sliding seat 43 will slide along the mounting strip 3, and the relative position between the sliding seat 43 and the mounting strip 3 changes, while the sliding seat 43 itself does not move, and the position of the adjustment motor 42 does not change either. After adjustment, the sliding seat 43 is used to assist in supporting the mounting strip 3, thereby assisting in fixing the display screen 1. In this way, the up, down, left, and right angles of the display screen 1 can be adjusted when using the in-vehicle display, and the distance from the user can also be adjusted, making it more convenient to use.

[0036] Such as Figures 5-10As shown in the figure, it further includes a placement mechanism. The placement mechanism includes an electric push rod 61, an extension plate 62, a fixed shaft 65, a sliding sleeve 66, a first elastic member 67, and a locking assembly. Electric push rods 61 are installed on both the left and right sides inside the connection frame 2. The bottom end of the telescopic rod of the electric push rod 61 is slidably connected to a sliding sleeve 66. A first elastic member 67 is connected between the sliding sleeve 66 and the telescopic rod of the electric push rod 61. The first elastic member 67 is a buffer spring. A fixed shaft 65 is rotatably connected between the bottoms of the two sliding sleeves 66. An extension plate 62 is connected to the fixed shaft 65. Items can be placed on the extension plate 62 for use, which is more convenient during use. A locking assembly is provided on the connection frame 2, and the locking assembly is used to lock the extension plate 62.

[0037] As Figures 8-10 shown in the figure, the locking assembly includes a locking bar 63, a connection plate 64, and a second elastic member 68. A connection plate 64 is connected to the front side of the inner bottom of the connection frame 2. A locking bar 63 is slidably connected to the inner bottom of the connection frame 2. The bottom of the locking bar 63 is provided with an inclined surface. A card slot is opened in the upper part of the front side of the extension plate 62. When the extension plate 62 swings upward, it can contact the locking bar 63 and thus squeeze the locking bar 63 to move. When the card slot is aligned with the locking bar 63, the locking bar 63 can catch the card slot, thereby fixing the extension plate 62. A plurality of second elastic members 68 are evenly spaced and connected between the locking bar 63 and the connection plate 64. The second elastic member 68 is a connection spring.

[0038] During the process of a user taking a vehicle, if an item needs to be placed on the vehicle, the telescopic rod of the electric push rod 61 can be controlled to extend, driving the sliding sleeve 66 to move downward. When the sliding sleeve 66 moves downward, it can drive the extension plate 62 and the fixed shaft 65 to move downward. When the fixed shaft 65 moves down to below the connection frame 2, it will be blocked by the connection frame 2. At this time, when the telescopic rod of the electric push rod 61 continues to move down, the first elastic member 67 will be compressed, and the first elastic member 67 is used for buffering to avoid hard connection between the electric push rod 61 and the fixed shaft 65, resulting in the fixed shaft 65 impacting the bottom of the connection frame 2. Then, the extension plate 62 is pulled to rotate forward by ninety degrees. After the extension plate 62 rotates, it will contact the locking bar 63 and squeeze the locking bar 63 to move forward, and the second elastic member 68 is stretched until the card slot on the extension plate 62 rotates to align with the locking bar 63. At this time, under the action of the second elastic member 68, the locking bar 63 resets and catches the card slot, thereby fixing the extension plate 62. At this time, items can be placed on the extension plate 62 for use, which is more convenient when placing items. When the extension plate 62 needs to be retracted, the locking bar 63 is pulled forward to disengage from the card slot, and then the telescopic rod of the electric push rod 61 is controlled to retract.

[0039] As Figures 11-13As shown in the figure, it further includes an automatic flipping mechanism. The automatic flipping mechanism includes a pressing shaft 71, a tripod 72, a connecting rack 73, a transmission gear 74, and an elastic member III 75. The telescopic rod of the electric push rod 61 is connected with a pressing shaft 71. Both the left and right sides of the inner bottom of the connecting frame 2 are slidably connected with a connecting rack 73. The top of the connecting rack 73 is connected with a tripod 72. The tripod 72 is located below the pressing shaft 71, so that the movement of the pressing shaft 71 can squeeze the tripod 72 to move. An elastic member III 75 is connected between the connecting rack 73 and the connecting frame 2. The elastic member III 75 is an elastic cord. Transmission gears 74 are connected to both the left and right sides of the fixed shaft 65. The transmission gears 74 are engaged with the connecting rack 73.

[0040] When the telescopic rod of the electric push rod 61 moves downward, it will drive the pressing shaft 71 to move downward together. When the fixed shaft 65 moves downward to below the connecting frame 2, the pressing shaft 71 also moves to contact the tripod 72. At this time, the pressing shaft 71 squeezes the tripod 72 to move backward, and the elastic member III 75 is stretched. When the tripod 72 moves, it drives the connecting rack 73 to move. When the connecting rack 73 moves, it can drive the transmission gear 74 to rotate. When the transmission gear 74 rotates, it can drive the fixed shaft 65 to rotate. The rotation of the fixed shaft 65 can drive the expansion plate 62 to rotate. In this way, the effect of automatically driving the expansion plate 62 to rotate can be achieved, which is more convenient during operation. When the telescopic rod of the electric push rod 61 resets, it can drive the pressing shaft 71 to reset. After the pressing shaft 71 resets, it no longer presses against the tripod 72. At this time, under the action of the elastic member III 75, the tripod 72 is pulled to reset. When the tripod 72 resets, it can drive the transmission gear 74 to reset through the connecting rack 73, thereby driving the fixed shaft 65 to rotate reversely and reset.

[0041] As Figure 14 shown in the figure, it further includes a shielding frame 8. The shielding frame 8 is connected to the edge position of the display screen 1. The shielding frame 8 can block the periphery of the display screen 1, thereby preventing direct sunlight from shining on the display screen 1 and causing reflection.

[0042] As Figure 15 shown in the figure, it further includes a shielding mechanism. The shielding mechanism includes a mounting frame 91, a shielding curtain 92, a winding shaft 94, and a winding motor 93. The mounting frame 91 is installed on the top of the shielding frame 8. A winding shaft 94 is rotatably connected inside the mounting frame 91. The shielding curtain 92 is wound on the winding shaft 94. The shielding curtain 92 is located in front of the display screen 1. The winding motor 93 is installed on the right side of the mounting frame 91. The output shaft of the winding motor 93 is connected to the winding shaft 94.

[0043] When the display screen 1 is not needed, the unwinding motor 93 can be controlled to operate to drive the unwinding shaft 94 to rotate, so as to lower the shielding curtain 92, block the display screen 1 with the shielding curtain 92, and prevent dust from adhering to the display screen 1. When the display screen 1 needs to be used, the unwinding motor 93 is controlled to drive the unwinding shaft 94 to rotate in the reverse direction to retract the shielding curtain 92.
