DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See attached Figure 1 -Attached Figure 6 and attached Figure 12 A multi-directional adjustment bracket for a car screen includes a base 1, a cross arm 2, a mounting plate 3 and a driving assembly 4; a support arm 11 is vertically provided on the base 1, and a wheel column 12 is provided on the support arm 11; the end of the cross arm 2 is rotatably connected to the wheel column 12, and a accommodating cavity 20 is provided inside the cross arm 2, and a movable opening 200 connected to the outside is opened on one side of the accommodating cavity 20; the mounting plate 3 is used to fix the screen, and a rotating block 30 is provided on the mounting plate 3, and the rotating block 30 is rotatably mounted at the movable opening 200; the driving assembly 4 is installed in the accommodating cavity 20 and includes a first driving member 41 and a second driving member 42, the first driving member 41 is drivingly connected to the wheel column 12 to drive the cross arm 2 to rotate around the axis of the support arm 11; the second driving member 42 is drivingly connected to the rotating block 30 to drive the mounting plate 3 to rotate around the axis of the cross arm 2.

[0036] Specifically, before use, fix the base 1 to the center console of the car and fix the screen on the mounting plate 3, so that the screen can be installed externally;

[0037] When in use, the first driving member 41 is activated to drive the cross arm 2 and the wheel column 12 to move relative to each other, thereby causing the cross arm 2 to rotate around the axis of the support arm 11 to adjust the rotational position of the mounting plate 3 and the screen in the vertical direction; the second driving member 42 is activated to drive the mounting plate 3 around the axis of the cross arm 2 to adjust the rotational position of the screen in the horizontal direction.

[0038] In summary, the utility model provides a support arm 11 on the base 1 for supporting the cross arm 2, and provides a first driving member 41 and a second driving member 42 in the cross arm 2, which are respectively used to drive the cross arm 2 and the mounting plate 3 to rotate, so that the bracket has multiple adjustment directions and can automatically adjust the display angle of the screen, thereby improving the comfort of use and the convenience of operation.

[0039] See attached Figure 3 -Attached Figure 7 The present invention also includes a limit member 5. The base 1 is provided with a vertically designed and upwardly open slide groove 13, and the support arm 11 can be slidably installed in the slide groove 13; the limit member 5 is installed on the base 1 and can limit the sliding position of the support arm 11 in the slide groove 13.

[0040] Specifically, under normal circumstances, the limiter 5 restricts the support arm 11 within the slide groove 13 to prevent the screen from moving up and down; when the screen height needs to be adjusted, the limiter 5 on the support arm 11 is released, and then the support arm 11 is moved up or down along the slide groove 13 to a suitable position, and finally the limiter 5 is used again to restrict and lock the support arm 11; therefore, the above design facilitates users to adjust the height position of the screen to further improve the comfort of use.

[0041] See attached Figure 3 -Attached Figure 7 The base 1 is provided with a through hole 130 connected to the slide groove 13, and the support arm 11 is provided with a plurality of lock holes 110 arranged in a vertical direction; the limiting member 5 is a bolt 50, which can pass through the through hole 130 and be threadedly connected to any lock hole 110.

[0042] Specifically, under normal circumstances, the bolt 50 passes through the through hole 130 and connects to any lock hole 110 to restrict the support arm 11 in the slide groove 13; when the screen height needs to be adjusted, the bolt 50 is turned to disengage the lock hole 110, and then the support arm 11 is moved up or down along the slide groove 13 to a suitable position so that the corresponding lock hole 110 is aligned with the through hole 130, and finally the bolt 50 is turned again to connect the lock hole 110 to restrict the support arm 11 to the current position.

[0043] It should be noted that, in addition to the above structure, the limiting member 5 can also use a buckle to abut and release the arm 11, or use other structures for locking. Due to the variety of types, this is not limited in the present invention.

[0044] See attached Figure 3 -Attached Figure 6 and attached Figure 10 -Attached Figure 12The structure of the first driving member 41 is diverse, and the present invention does not impose any restrictions on this. For ease of understanding, in this embodiment, the first driving member 41 includes a first motor 411, a first bevel gear 412 and a second bevel gear 413. The first motor 411 is horizontally arranged, and the first bevel gear 412 is mounted on the output shaft of the first motor 411. The second bevel gear 413 is mounted on the wheel column 12 and meshed with the first bevel gear 412, so as to drive the cross arm 2 to rotate around the axis of the support arm 11 through the first motor 411.

[0045] Specifically, when in use, the first motor 411 is started to drive the first bevel gear 412 to rotate. Since the second bevel gear 413 is fixedly mounted on the wheel column 12 and the base 1 is fixed on the car, the first bevel gear 412 will move along the circumferential direction of the second bevel gear 413, thereby causing the cross arm 2 to rotate around the axis of the support arm 11; by controlling the first motor 411 to rotate forward or reverse, the screen display angle can be adjusted in the vertical direction.

[0046] See attached Figure 8 -Attached Figure 11 A stopper 414 is provided on the second bevel gear 413 , and a first limit block 21 and a second limit block 22 are installed in the end of the cross arm 2 , which can correspondingly abut the stopper 414 .

[0047] Specifically, when the cross arm 2 rotates forward around the support arm 11, the stopper 414 can abut the first limit block 21; similarly, when the cross arm 2 rotates reversely around the support arm 11, the stopper 414 can abut the second limit block 22; therefore, the coordinated use of the stopper 414, the first limit block 21 and the second limit block 22 can limit the rotation range of the cross arm 2, thereby preventing the screen from rotating excessively and colliding with the car's center console.

[0048] See attached Figure 3 -Attached Figure 4 and attached Figure 9 -Attached Figure 10 The present invention also includes a first damper 6, which is installed in the support arm 11; a first rotating rod 23 is vertically installed in the end of the cross arm 2, and the first rotating rod 23 rotatably passes through the second bevel gear 413 and the wheel column 12, and is connected to the first damper 6.

[0049] Specifically, when the cross arm 2 rotates around the support arm 11, the first damper 6 can slow down the rotation speed of the cross arm 2 by limiting the first rotating rod 23. On the one hand, this design can provide support for the cross arm 2 and improve the connection stability between the support arm 11 and the cross arm 2; on the other hand, it can buffer the internal stress generated by the operation of the first motor 411, the first bevel gear 412 and the second bevel gear 413, reduce the wear of the first drive member 41, and extend the overall service life.

[0050] See attached Figure 6-Attached Figure 11 The structure of the second driving member 42 is diverse, and the present invention does not impose any restrictions on this. For ease of understanding, in this embodiment, the second driving member 42 includes a second motor 421, a driving gear 422 and an arc-shaped rack 423; the second motor 421 is horizontally arranged, and the driving gear 422 is mounted on the output shaft of the second motor 421. The arc-shaped rack 423 is mounted on the rotating block 30 and meshed with the driving gear 422 to drive the mounting plate 3 to rotate around the axis of the cross arm 2 through the second motor 421.

[0051] Specifically, when in use, the second motor 421 is started to drive the driving gear 422 to rotate, and the driving gear 422 drives the arc rack 423, thereby causing the rotating block 30 and the mounting plate 3 to rotate around the axis of the cross arm 2; by controlling the second motor 421 to rotate forward or reverse, the screen display angle can be adjusted in the horizontal direction.

[0052] See attached Figure 9 -Attached Figure 11 The first motor 411 and the second motor 421 are both electrically connected and are equipped with encoders 43 .

[0053] Specifically, the encoder 43 can be used in conjunction with the built-in program of the vehicle computer to facilitate the user to control the operating timing of the first motor 411 body and the second motor 421 body through the screen, thereby further improving the operational convenience; since the technology of controlling the operation of the motor through the screen and the encoder 43 is relatively common, the circuit principle thereof is not elaborated in detail in this utility model.

[0054] See attached Figure 6 and attached Figure 9 -Attached Figure 11 The present invention also includes a second damper 7, which is mounted on the cross arm 2; a second rotating rod 31 is provided on the rotating block 30, and the rotating block 30 is rotatably mounted at the movable opening 200 through the second rotating rod 31, and the second rotating rod 31 passes through the movable opening 200 and is connected to the second damper 7.

[0055] Specifically, when the rotating block 30 rotates around the cross arm 2, the second damper 7 can slow down the rotation speed of the rotating block 30 by limiting the second rotating rod 31. This design can buffer the internal stress generated by the second driving member 42 during operation, reduce the wear of the second driving member 42, and extend the overall service life.

[0056] See attached Figure 3 -Attached Figure 4 A bearing 8 is provided at the rotational connection between the cross arm 2 and the wheel column 12. This design can reduce the friction between the wheel column 12 and the cross arm 2 and improve the rotational stability between the cross arm 2 and the support arm 11.

[0057] It should also be noted that although the embodiments of the present application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present application.
