Description

Technical Field

[0001] The present application relates to the field of vehicle-mounted equipment, and in particular to a multi-directional adjustment bracket for a vehicle-mounted display screen and an installation method thereof. Background Art

[0002] In-vehicle displays are an important carrier of vehicle information interaction. In order to meet the needs of different users for the angle of in-vehicle displays, the industry has put forward higher requirements for its installation method and adjustment performance.

[0003] However, most vehicle-mounted display screens currently available on the market are fixed or simply adjustable. To address the angle adjustment issue, existing technologies typically employ a simple rotating shaft structure to achieve limited angle adjustment. While this approach is relatively simple, it also offers a limited adjustment range, low stability, and the ability to easily loosen. This is especially true when the vehicle is in motion, where vibration can easily cause the display screen to loosen or shift, impacting the user experience. Therefore, a solution for a vehicle-mounted display screen bracket that offers multi-directional angle adjustment, a stable structure, and easy assembly and disassembly is urgently needed. Summary of the Invention

[0004] In order to improve the above-mentioned problems, the present application provides a multi-directional adjustment bracket for a vehicle-mounted display screen.

[0005] The present application provides a multi-directional adjustable bracket for a vehicle-mounted display screen using the following technical solutions:

[0006] A multi-directional adjustment bracket for a vehicle-mounted display screen, comprising a base, a mounting shell, a fastening handle, a movable seat and a screen seat; the mounting shell is a shell structure that opens and closes left and right, with a threaded opening in the middle section, a first spherical groove on the top, and a second spherical groove on the bottom; the base is provided with a first spherical structure, which is movably connected to the first spherical groove; the movable seat is provided with a second spherical structure, which is movably connected to the second spherical groove; the screen seat is connected to an external display screen and is slidably connected to the movable seat, the display screen is deflected in the first spherical groove by the first spherical structure, and the second spherical structure is deflected in the second spherical groove to adjust any angle; the fastening handle is provided with an external thread, which is screwed to the threaded opening through the external thread to lock and close the first spherical groove and the second spherical groove, so that the first spherical structure and the second spherical structure are fastened to fix the angle of the display screen.

[0007] By adopting the above technical solution, the mounting shell can pivot along the first spherical groove to adjust the mounting position and angle of the mounting shell, and the movable seat pivots along the second spherical groove through the second spherical structure to adjust the mounting position and angle of the movable seat, and the movable seat is slidingly connected to the screen seat, so that the external display screen can freely adjust the mounting position and angle through the screen seat and the movable seat, and then the fastening handle is used to close and lock the mounting shell, so that the first spherical structure and the second spherical structure are fastened to fix the angle of the display screen after the adjustment is completed, so as to achieve convenient and flexible adjustment of the display screen angle while improving the stability of the connection.

[0008] Optionally, the movable seat further includes a sliding portion, the screen seat is provided with a sliding groove with one end open, the sliding portion is embedded in the sliding groove, and slides along the sliding groove.

[0009] By adopting the above technical solution, the sliding seat is limited by the sliding groove, thereby ensuring that the installation positions of the sliding part and the movable seat are accurate and the installation effect is stable.

[0010] Optionally, the sliding portion is a T-shaped block, and the sliding groove is a T-shaped groove.

[0011] By adopting the above technical solution, the T-block and T-slot can be used to make the connection between the screen seat and the movable seat more stable and reduce looseness.

[0012] Optionally, the movable seat also includes a locking screw; the locking screw is connected to the sliding part, and an insertion interface is provided in the second spherical structure, and the sliding part is plugged into the insertion interface through the locking screw; a locking nut is threaded onto the other end of the locking screw.

[0013] By adopting the above technical solution, the sliding part can be easily separated from or installed with the second spherical structure by means of a locking screw, and the connection stability between the sliding part and the screen seat can be increased. That is, after the sliding part and the screen seat are inserted, the locking nut is rotated so that the locking nut is pressed against the second spherical structure by the locking screw, so that the sliding part is used to clamp the screen seat between the second spherical structure and the sliding part, so that the sliding part cannot continue to slide along the sliding groove, thereby fixing the position of the sliding part on the sliding groove and making the connection more stable.

[0014] Optionally, the movable seat further includes an anti-slip rubber pad; the anti-slip rubber pad is installed at an end of the second spherical structure away from the second spherical groove and abuts against the sliding part.

[0015] By adopting the above technical solution, when the locking screw is continuously tightened in conjunction with the locking nut, the sliding part is firmly connected to the screen seat, and at the same time, the anti-slip rubber pad is pressed down. The anti-slip rubber pad provides anti-slip performance when the sliding part is connected, and also provides a certain buffering performance. The pressure applied by the anti-slip rubber pad to the sliding part toward the second spherical structure will reduce the clamping force.

[0016] Optionally, the base is further provided with a stabilizing mechanism, which provides additional support for the mounting shell.

[0017] By adopting the above technical solution, the stabilizing mechanism provides additional support for the first spherical structure, thereby increasing the stability of the connection of the first spherical structure.

[0018] Optionally, the stabilizing mechanism includes a stabilizing tube and an extension tube; the stabilizing tube is connected to the base, and the connection point between the first spherical structure and the base is located inside the stabilizing tube; the inner wall of the stabilizing tube is provided with an external thread, the outer wall of the extension tube is provided with an internal thread, and the outer diameter of the stabilizing tube matches the inner diameter of the extension tube; the extension tube is threadedly connected to the stabilizing tube through the external thread, and when extending along the stabilizing tube toward away from the base, it wraps the mounting shell.

[0019] By adopting the above technical solution, the extension tube can be raised and lowered by rotating along the stabilizing tube using the external thread. When the extension tube rotates along the stabilizing tube and extends away from the base and rises, it can move to the outer wall of the mounting shell and wrap the mounting shell, thereby pressing against the mounting shell to provide additional support for the mounting shell.

[0020] Optionally, the stabilizing cylinder and the extending cylinder are both separated by two half-cylinder structures, and a fastening ring is provided between the two half-cylinder structures.

[0021] By adopting the above technical solution, the two half-cylinder structures can bear against the two outer walls of the mounting shell, so that the mounting shell can not only be subjected to force through the first spherical structure, but also be supported by the stabilizing cylinder and the extension cylinder. The gap between the half-cylinder structures allows the first spherical structure to extend from the gap when the mounting shell is tilted and bent, thereby avoiding interference.

[0022] Optionally, a pivot groove is further provided on the base; the pivot groove consists of two semicircular grooves, and there is a gap between the two semicircular grooves, and they are not connected to each other; two limiting sliders are provided at the bottom of the stabilizing cylinder, and the two limiting sliders are respectively embedded in the two pivot grooves and slide along the pivot grooves.

[0023] By adopting the above technical solution, the pivot groove is used to rotate the spacing space between the stabilizing tube and the extension tube to the corresponding bending direction of the mounting shell to adapt to the bending of the mounting shell from different directions. After the limiting slider is abutted against the groove wall of the semicircular groove, the extension tube can continue to rotate, avoiding the situation where the stabilizing tube rotates synchronously when the extension tube rotates.

[0024] A method for installing the multi-directional adjustable bracket includes the following steps:

[0025] Loosen the fastening handle to loosen the mounting shell, remove the base from the first spherical groove, and fix the base on the vehicle instrument panel;

[0026] Install the screen holder on the display screen, and use the movable seat to slide and connect it with the screen holder;

[0027] inserting the second spherical structure into the second spherical groove;

[0028] Adjusting the directions of the mounting shell and the display screen by using the first spherical structure and the second spherical structure;

[0029] After selecting the direction of the display screen, the mounting shell is locked by tightening the handle, closing the first spherical groove and the second spherical groove, fixing the first spherical structure and the second spherical structure, and completing the installation.

[0030] By adopting the above technical solution, the multi-directional adjustment bracket can be conveniently installed on the vehicle platform through the installation method.

[0031] In summary, this application includes at least one of the following beneficial technical effects:

[0032] 1. The mounting shell can be pivoted along the first spherical groove to adjust the mounting position and angle of the mounting shell, and the movable seat can be pivoted along the second spherical groove through the second spherical structure to adjust the mounting position and angle of the movable seat. The movable seat is slidably connected to the screen seat, so that the external display screen can be freely adjusted in mounting position and angle through the screen seat and the movable seat. The mounting shell is then closed and locked using the tightening handle, so that the first spherical structure and the second spherical structure are tightened to fix the angle of the display screen after adjustment, thereby achieving convenient and flexible adjustment of the display screen angle while improving the stability of the connection;

[0033] 2. Use the sliding groove to limit the sliding seat to ensure the accurate installation position of the sliding part and the movable seat and the stable installation effect;

[0034] 3. Using T-blocks and T-slots can make the connection between the screen seat and the movable seat more stable and reduce looseness;

[0035] 4. The use of a locking screw can facilitate the separation or installation of the sliding part from the second spherical structure, and can also increase the stability of the connection between the sliding part and the screen seat. That is, after the sliding part and the screen seat are inserted, the locking nut is rotated so that the locking nut is pressed against the second spherical structure by the locking screw, so that the sliding part is used to clamp the screen seat between the second spherical structure and the sliding part, so that the sliding part cannot continue to slide along the sliding groove, thereby fixing the position of the sliding part on the sliding groove and making the connection more stable.

[0049] Throughout this specification, when a device is said to be "connected" to another device, this includes not only "direct connection" but also "indirect connection" with other elements interposed therebetween. Furthermore, when a device is said to "include" a certain component, unless otherwise stated, this does not exclude the inclusion of other components but rather implies that the device may include other components.

[0050] The following is combined with Figure 1 -Attached Figure 8 , further details of this application are given.

[0051] An embodiment of the present application discloses a multi-directional adjustment bracket for a vehicle-mounted display screen.

[0052] A multi-directional adjustment bracket for vehicle-mounted display screen, reference Figure 1 As shown, it includes a base 1, a mounting shell 2, a fastening handle 3, a movable seat 4 and a screen seat 5; the mounting shell 2 is a shell structure that opens and closes left and right, that is, two half-open shells, and when the openings of the two shells are fitted together, a complete mounting shell 2 is formed.

[0053] A threaded opening is provided in the middle section of the mounting shell 2, and threaded openings are provided on both the left and right half shells. A first spherical groove 21 is provided on the top, and a second spherical groove 22 is provided on the bottom. Both the first spherical groove 21 and the second spherical groove 22 are hemispherical grooves. When the left and right half shells are fitted together, a complete spherical groove is formed, and openings are provided on both sides of the spherical groove.

[0054] refer to Figure 1 and Figure 2As shown, the base 1 is provided with a first spherical structure 11, which is movably connected to the first spherical groove 21, and the movable seat 4 is installed with a second spherical structure 41, which is movably connected to the second spherical groove 22. The base 1 can be installed on the instrument panel of the vehicle, and the connection method can be screw connection. After the first spherical structure 11 is movably connected to the second spherical groove 22, the mounting shell 2 can be pivoted along the first spherical groove 21, thereby adjusting the installation orientation and angle of the mounting shell 2, and the movable seat 4 is pivoted along the second spherical groove 22 through the second spherical structure 41, thereby adjusting the installation orientation and angle of the movable seat 4.

[0055] The screen holder 5 is connected to the external display screen 7 and is slidably connected to the movable seat 4. Specifically, the screen holder 5 is connected to the back of the display screen 7. The connection method can be multiple bolt locking, so that the external display screen 7 can adjust the installation orientation and angle through the screen holder 5 and the movable seat 4, that is, the display screen 7 is deflected in the first spherical groove 21 through the first spherical structure 11, and the movable seat 4 is deflected in the second spherical groove 22 through the second spherical structure 41, so that the display screen 7 can be adjusted to any angle, thereby improving the flexibility of the display screen 7.

[0056] The fastening handle 3 is provided with an external thread, which is screwed to the threaded mouth through the external thread. The fastening handle 3 can be used to close and lock the two side half shells of the mounting shell 2, so that the first spherical groove 21 and the second spherical groove 22 are gradually closed and the first spherical structure 11 and the second spherical structure 41 are locked in the first spherical groove 21 and the second spherical groove 22, so that the first spherical structure 11 and the second spherical structure 41 are fastened to fix the angle of the display screen 7 after the adjustment is completed. When it is necessary to adjust again, the fastening handle 3 is loosened, the first spherical groove 21 and the second spherical groove 22 are loosened, and the mounting shell 2 and the movable seat 4 can be rotated again through the first spherical structure 11 and the second spherical structure 41 to adjust the installation angle of the display screen 7.

[0057] For further reference, Figure 3 As shown, the movable seat 4 also includes a sliding portion 42, and the screen seat 5 is provided with a sliding groove 51 with an open end. The bottom of the sliding groove 51 is provided with an embedding opening, so that the sliding portion 42 can be embedded in the sliding groove 51 and slide along the sliding groove 51. The movable seat 4 is connected to the screen seat 5 by the sliding portion 42. When the sliding portion 42 slides along the sliding groove 51, when the display screen 7 is released, the display screen 7 will be affected by gravity and press against the sliding portion 42, so that the sliding portion 42 will not separate from the sliding groove 51 from the embedding opening. The sliding groove 51 is used to limit the sliding seat to ensure that the installation position of the sliding portion 42 and the movable seat 4 is accurate and the installation effect is stable.

[0058] Furthermore, the sliding portion 42 is a T-shaped block, and the sliding groove 51 is a T-shaped groove. The sliding portion 42 adopts a T-shaped block structure, so that it can be just embedded in the T-shaped groove of the sliding groove 51. The T-shaped structure can prevent the sliding portion 42 from separating from the sliding groove 51, while it can slide along the groove surface that is also T-shaped. The use of the T-block and the T-shaped groove can make the connection between the screen seat 5 and the movable seat 4 more stable and reduce looseness.

[0059] In some embodiments, reference Figure 4 As shown, the movable seat 4 also includes a locking screw 43, which is connected to the sliding part 42, so that the locking screw 43 can drive the sliding part 42 to move or fix. A plug-in interface is provided in the second spherical structure 41, and the sliding part 42 is plugged into the plug-in interface through the locking screw 43. When the locking bolt is inserted into the plug-in interface, the sliding part 42 is synchronously installed on one end of the second spherical structure 41, and the other end of the locking screw 43 is threaded with a locking nut 44. The locking screw 43 is fixed in the plug-in interface by using the locking nut 44, so that the position of the locking screw 43 is fixed, thereby fixing the position of the sliding part 42.

[0060] The use of the locking screw 43 can facilitate the separation or installation of the sliding part 42 from the second spherical structure 41, and can also increase the stability of the connection between the sliding part 42 and the screen seat 5. That is, after the sliding part 42 and the screen seat 5 are inserted, the locking nut 44 is rotated so that the locking nut 44 is affected by the locking screw 43 to press the second spherical structure 41, so that the sliding part 42 is used to clamp the screen seat 5 between the second spherical structure 41 and the sliding part 42, so that the sliding part 42 cannot continue to slide along the sliding groove 51, fixing the position of the sliding part 42 on the sliding groove 51 and making the connection more stable.

[0061] For further reference, Figure 3 or Figure 4 As shown, the movable seat 4 also includes an anti-slip rubber pad 45. The anti-slip rubber pad 45 is installed at the end of the second spherical structure 41 away from the second spherical groove 22, and abuts against the sliding part 42. When the locking screw 43 is continuously tightened in conjunction with the locking nut 44, the sliding part 42 is firmly connected to the screen seat 5, and the anti-slip rubber pad 45 is pressed down at the same time. The anti-slip rubber pad 45 provides anti-slip performance when the sliding part 42 is connected, and also provides a certain buffering performance. The pressure applied by the anti-slip rubber pad 45 to the sliding part 42 toward the second spherical structure 41 will reduce the clamping force, thereby avoiding excessive tightening force of the locking bolt, which will cause the screen seat 5 to be damaged due to excessive abutment pressure with the second spherical structure 41.

[0062] In some embodiments, reference Figure 5As shown, the base 1 is also provided with a stabilizing mechanism 6, which provides additional support for the first spherical structure 11. The first spherical structure 11 mainly functions to provide adjustment of the rotational orientation of the second spherical structure 41. By rotating the mounting shell 2 along the first spherical structure 11, the extension position of the second spherical structure 41 can be adjusted, and the inclination angle of the mounting shell 2 can also be adjusted. However, if only the first spherical structure 11 is used to support the entire mounting shell 2 and the display screen 7, they are easily damaged by bumps. Therefore, additional support for the mounting shell 2 is provided by the stabilizing mechanism 6 to increase the stability of the connection of the mounting shell 2.

[0063] For further reference, Figure 6 As shown, the stabilizing mechanism 6 includes a stabilizing cylinder 61 and an extension cylinder 62; the stabilizing cylinder 61 is connected to the base 1, and the connection point between the first spherical structure 11 and the base 1 is located inside the stabilizing cylinder 61, the inner wall of the stabilizing cylinder 61 is provided with an external thread, and the outer wall of the extension cylinder 62 is provided with an internal thread, and the outer diameter of the stabilizing cylinder 61 matches the inner diameter of the extension cylinder 62, that is, the extension cylinder 62 can just wrap around the stabilizing cylinder 61, and the extension cylinder 62 is screwed to the stabilizing cylinder 61 through the external thread, so that the extension cylinder 62 can be raised and lowered by rotating along the stabilizing cylinder 61 using the external thread, and when the extension cylinder 62 rotates along the stabilizing cylinder 61 and extends in the direction away from the base 1, it can move to the outer wall of the mounting shell 2 and wrap the mounting shell 2, thereby pressing against the mounting shell 2 to provide additional support for the mounting shell 2.

[0064] When the rotation angle of the mounting shell 2 needs to be adjusted, the extension tube 62 is rotated toward the base 1 so that the extension tube 62 moves toward the base 1 along the stabilizing tube 61 and overlaps with the stabilizing tube 61. The mounting shell 2 loses the fixation of the extension tube 62 and can be rotated or the angle adjusted along the first spherical structure 11.

[0065] refer to Figure 7 As shown, when the mounting shell 2 is tilted to adjust the angle, the extension tube 62 can be rotated and moved toward the mounting shell 2 with the adjusted angle, and finally abuts against the bottom of the mounting shell 2, thereby bearing part of the pressure of the mounting shell 2 and providing additional support.

[0066] For further reference, Figure 6 As shown, the stabilizing cylinder 61 and the extending cylinder 62 are both separated by two semi-cylinder structures, and a fastening ring is provided between the two semi-cylinder structures. The two semi-cylinder structures can support the two outer walls of the mounting shell 2, so that the mounting shell 2 can not only provide force through the first spherical structure 11, but also provide support through the stabilizing cylinder 61 and the extending cylinder 62.

[0067] The gaps between the semi-cylinder structures allow the first spherical structure 11 to extend from the gaps when the mounting shell 2 is tilted and bent, thereby avoiding interference.

[0068] Further, refer to Figure 8 As shown, a pivot groove 12 is also provided on the base 1, and the pivot groove 12 consists of two semicircular grooves, and there is a gap between the two semicircular grooves, and they are not connected to each other. Two limiting sliders 611 are provided at the bottom of the stabilizing cylinder 61, and the two limiting sliders 611 are respectively embedded in the two pivot grooves 12 and slide along the pivot groove 12. The stabilizing cylinder 61 can slide along the pivot groove 12 through the limiting slider 611, so that the stabilizing cylinder 61 can be rotated. After rotation, the positions of the stabilizing cylinder 61 and the extension cylinder 62 are changed. The pivot groove 12 is used to rotate the spacing space between the stabilizing cylinder 61 and the extension cylinder 62 to the bending direction of the mounting shell 2, so that when the mounting shell 2 is bent from different directions, the spacing position between the semi-cylinder structures of the stabilizing cylinder 61 and the extension cylinder 62 can be changed by the pivot groove 12 for adaptation.

[0069] By adjusting the position of the mounting shell 2 through the pivot slot 12, you can choose whether to use the extension tube 62 to press against the outer wall of the mounting shell 2. If not, rotate the extension tube 62 and the stabilizing tube 61 so that the interval between the half-tube structures corresponds to the inclination of the mounting shell 2, so that the extension tube 62 and the stabilizing tube 61 can be adjusted according to user needs.

[0070] The purpose of the two semicircular grooves being separated and not connected to each other is to prevent the limiting slider 611 from sliding into the other semicircular groove, thereby limiting the rotation direction of the stabilizing cylinder 61 and preventing the stabilizing cylinder 61 from rotating a circle. In this way, when the stabilizing cylinder 61 reaches the end wall of the semicircular groove through the limiting slider 611, the stabilizing cylinder 61 can no longer rotate, so that the extension cylinder 62 can continue to rotate, avoiding the situation where the stabilizing cylinder 61 rotates synchronously with the extension cylinder 62, resulting in the extension cylinder 62 being unable to rise or fall along the stabilizing cylinder 61.

[0071] The present application also provides an installation method, which is applied to the above-mentioned adjustment bracket and includes the following steps:

[0072] S1: Loosen the fastening handle 3 to loosen the mounting shell 2, remove the base 1 from the first spherical groove 21, and fix the base 1 on the vehicle instrument panel.

[0073] S2: Install the screen holder 5 on the display screen 7, and use the movable seat 4 to slide and connect with the screen holder 5;

[0074] S21 : inserting the sliding portion 42 into the sliding groove 51 , inserting the locking screw 43 into the second spherical structure 41 , and screwing the locking screw 43 into the second spherical structure 41 using the locking nut 44 .

[0075] S3: inserting the second spherical structure 41 into the second spherical groove 22;

[0076] S4: Adjust the directions of the mounting shell 2 and the display screen 7 by using the first spherical structure 11 and the second spherical structure 41 .

[0077] S5: After selecting the direction of the display screen 7, the mounting shell 2 is locked by tightening the handle 3, closing the first spherical groove 21 and the second spherical groove 22, fixing the first spherical structure 11 and the second spherical structure 41, and completing the installation.

[0078] To disassemble, follow the reverse steps.

[0079] Among them, step S2 and step S3 can be swapped.

[0080] The examples of this specific embodiment are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, any equivalent changes made based on the structure, shape, and principle of this application should be included in the scope of protection of this application.
