DETAILED DESCRIPTION

[0021] The following is combined with Figure 1-3 This application is described in further detail.

[0022] The embodiments of the present application disclose a vehicle-mounted display screen adjustment device and a vehicle.

[0023] Reference Figure 1 and Figure 2 The vehicle-mounted display screen adjustment device includes a housing 100, to which a support frame 200 is rotatably connected, and a vehicle-mounted display screen 500 is rotatably connected. The housing 100 is provided with a first drive unit 300 for driving the support frame 200 to angularly deflect relative to the housing 100; and the support frame 200 is provided with a second drive unit 400 for rotating the vehicle-mounted display screen 500. In the embodiment of the present application, the support frame 200 can be designed as a separate structure based on the installation space within the vehicle. The separate structures are connected by bolts to form a single support frame 200, thereby facilitating disassembly and installation.

[0024] Therefore, the first drive unit 300 is started to drive the support frame 200 to deflect at an angle relative to the shell 100, thereby realizing the left and right swing of the vehicle-mounted display screen 500 on the support frame 200, which can simultaneously meet the convenient use of the main driver and the co-driver in the car. The second drive unit 400 is started to drive the vehicle-mounted display screen 500 to rotate, thereby realizing the horizontal and vertical position transformation of the vehicle-mounted display screen 500 itself, which is more flexible and meets the more complex human-computer adjustment interaction needs of the people in the car. By using the first drive unit 300 and the second drive unit 400, the vehicle-mounted display screen 500 can achieve dual-degree-of-freedom movement.

[0025] Reference Figure 1 and Figure 2The second drive unit 400 includes a disk motor 410 mounted on the support frame 200. A connecting plate 420 is mounted on the output end of the disk motor 410. The vehicle display 500 is bolted to the connecting plate 420. Therefore, when the disk motor 410 is activated, the connecting plate 420 at the output end of the disk motor 410 rotates, which in turn drives the vehicle display 500 on the connecting plate 420 to rotate synchronously. This allows the vehicle display 500 to change its horizontal and vertical positions, providing greater flexibility and meeting the more complex human-machine interaction needs of vehicle occupants.

[0026] Reference Figure 1 and Figure 2 The first drive unit 300 includes a mounting frame 310 rotatably connected to the housing 100. In the embodiment of the present application, the mounting frame 310 is die-cast. A drive motor 320 is mounted on the mounting frame 310, and a lead screw 330 is rotatably connected to the mounting frame 310. The output end of the drive motor 320 is provided with a transmission assembly for driving the lead screw 330 to rotate. The outer edge of the lead screw 330 is threadedly connected to a nut 340 of a size matching the lead screw 330. The support frame 200 is rotatably connected to the nut 340, and the support frame 200 is rotatably connected to the housing 100 via the support assembly. The transmission assembly includes a worm 350 disposed at the output end of the drive motor 320. In the embodiment of the present application, the worm 350 is coaxial with the output shaft of the drive motor 320 and is fixedly disposed. A worm wheel 360 of a size matching the worm 350 is disposed on the end of the lead screw 330 facing the drive motor 320, and the worm wheel 360 and the worm 350 are meshed with each other.

[0027] Therefore, the drive motor 320 is started to drive the worm 350 at the output end of the drive motor 320 to rotate. Since the worm 350 and the turbine are engaged with each other, the worm 350 drives the turbine to rotate, and the turbine drives the lead screw 330 to rotate synchronously, so that the nut 340 moves along the direction of the lead screw 330. While the nut 340 is displaced, it drives the support frame 200 to deflect at an angle relative to the shell 100, thereby driving the vehicle-mounted display screen 500 on the support frame 200 to swing left and right, which can meet the convenient use of the main driver and the co-driver in the car at the same time.

[0028] Reference Figure 2 and Figure 3 The support assembly includes a connecting frame 210 bolted to the support frame 200. The connecting frame 210 is rotatably connected to a nut 340. A first rotating shaft 220 is provided on the connecting frame 210. A first rotating groove matching the size of the first rotating shaft 220 is defined in the housing 100. The first rotating shaft 220 is rotatably connected to the first rotating groove. Therefore, the first rotating groove limits the position of the first rotating shaft 220 and also supports the connecting frame 210, reducing the possibility of positional displacement of the connecting frame 210 during left-right yaw and improving the stability of the connecting frame 210 during rotation.

[0029] Reference Figure 2 and Figure 3 The nut 340 is fixedly connected to two connecting columns 341 in the vertical direction. The nut 340 is located between the two connecting columns 341. Two connecting holes 211 matching the size of the connecting columns 341 are provided on the connecting frame 210. The two connecting columns 341 are rotatably connected in the two connecting holes 211 respectively. Guide flats 342 are relatively provided on the outer edges of the connecting columns 341, and guide holes 343 are provided on the hole walls of the connecting holes 211. When the operator installs the connecting frame 210, the guide flats 342 can pass through the guide holes 343 and then be rotatably connected in the connecting holes 211, which is convenient for installation.

[0030] Reference Figure 2 and Figure 3 A second rotating shaft 311 is provided on the mounting frame 310, and a second rotating groove matching the size of the second rotating shaft 311 is opened on the shell 100. The second rotating shaft 311 is rotatably connected in the second rotating groove, and a bushing 312 matching the size of the second rotating groove is installed in the second rotating groove. The second rotating shaft 311 is rotatably connected to the inner edge of the bushing 312. The bushing 312 can reduce the wear between the second rotating shaft 311 and the shell 100, and is used to support the load on the second rotating shaft 311 while having self-lubrication and low operating noise, meeting the quiet use requirements inside the vehicle. A wear-resistant ring 314 is fixedly connected to the surface of the bushing 312 facing the mounting frame 310, and a wear-resistant plate 313 is clamped on the mounting frame 310. The second rotating shaft 311 passes through the wear-resistant plate 313 and the wear-resistant ring 314 in sequence, and the end surface of the wear-resistant plate 313 facing the bushing 312 is in contact with the wear-resistant ring 314. In the embodiment of the present application, the wear-resistant plate 313 is made of highly wear-resistant material, which effectively reduces the friction and wear between the wear-resistant ring 314 and the mounting frame 310 when the second rotating shaft 311 rotates, thereby extending the service life of the die-cast mounting frame 310.

[0031] The implementation principle of the embodiment of the present application is as follows: starting the drive motor 320 to drive the worm 350 at the output end of the drive motor 320 to rotate. Since the worm 350 and the turbine are meshed with each other, the worm 350 drives the turbine to rotate, and the turbine drives the screw 330 to rotate synchronously, so that the nut 340 moves along the direction of the screw 330. While the nut 340 is displaced, it drives the support frame 200 to deflect at an angle relative to the shell 100, thereby driving the vehicle-mounted display screen 500 on the support frame 200 to swing left and right, which can simultaneously meet the convenience of use of the main driver and the co-driver in the car; starting the disk motor 410 to drive the connecting plate 420 at the output end of the disk motor 410 to rotate, driving the vehicle-mounted display screen 500 on the connecting plate 420 to rotate synchronously, thereby realizing the horizontal and vertical position change of the vehicle-mounted display screen 500 itself, which is more flexible and meets the more complex human-machine adjustment interaction needs of the occupants in the car; using the first drive unit 300 and the second drive unit 400, the vehicle-mounted display screen 500 can achieve dual-degree-of-freedom movement.
