Detailed Implementation

[0032] The following is in conjunction with the appendix Figures 1-6 This application will be described in further detail.

[0033] This application discloses a display screen that can be adjusted to multiple angles. (See also...) Figure 1 The multi-angle adjustable display screen includes a fixed housing 1 and a display screen body 11. The top surface of the fixed housing 1 is provided with a mounting groove 12 for placing the display screen body 11.

[0034] Reference Figure 2 and Figure 3 A mounting rod 13 is vertically slidable inside the fixed housing 1, with its top end hinged to the back of the display screen body 11. A vertically mounted height adjustment screw 2 is rotatably mounted inside the fixed housing 1, and a movable circular groove 21 for the height adjustment screw 2 to pass through is provided on the bottom surface of the mounting rod 13. A drive block 22 is rotatably mounted at the bottom end of the mounting rod 13, and the drive block 22 is sleeved on the outer periphery of the height adjustment screw 2, with the drive block 22 and the height adjustment screw 2 having a threaded transmission engagement. A guide rod 23 is installed inside the fixed housing 1, and the drive block 22 is sleeved on the outer periphery of the guide rod 23, with the guide rod 23 providing guidance for the drive block 22. A synchronous pulley 1 24 and a synchronous pulley 25 are rotatably mounted inside the fixed housing 1, and a synchronous belt 26 is wound around the outer periphery of the synchronous pulley 1 24 and the synchronous pulley 25. Synchronous pulley 24 is fixed to the outer periphery of height adjusting screw 2. Motor 27 is fixed inside the fixed housing 1. The output end of motor 27 is coaxially and fixedly connected to the rotation shaft of synchronous pulley 25.

[0035] Start motor 27, which drives synchronous pulley 25 to rotate. Synchronous pulley 25 drives height adjustment screw 2 to rotate via synchronous belt 26 and synchronous pulley 24. Height adjustment screw 2 drives drive block 22 to move vertically. Drive block 22 drives mounting rod 13 and display screen body 11 to move vertically, thereby adjusting the height of display screen body 11.

[0036] ReferenceFigure 4 A limiting gear 3 is rotatably installed inside the fixed housing 1, and the limiting gear 3 is sleeved on the outer periphery of the mounting rod 13. A limiting block 31 is fixed on the inner peripheral surface of the limiting gear 3, and a limiting groove 32 is opened on the outer peripheral surface of the mounting rod 13. The limiting groove 32 is set along the length direction of the mounting rod 13, and the limiting block 31 slides and engages with the mounting rod 13 vertically through the limiting groove 32.

[0037] Reference Figure 2 and Figure 5 The inner wall of the fixed housing 1 is provided with a snap-fit ​​groove 34. A snap-fit ​​block 33 is installed on the fixed housing 1 by sliding along the radial direction of the limiting gear 3 through the snap-fit ​​groove 34. A tip 331 is fixed on the side of the snap-fit ​​block 3 near the limiting gear 3, and the tip 331 can be inserted into the tooth groove of the limiting gear 3. A snap-fit ​​spring 35 is fixed on the side of the snap-fit ​​block 3 away from the limiting gear 3. The end of the snap-fit ​​spring 35 away from the snap-fit ​​block 33 is fixedly connected to the inner wall of the snap-fit ​​groove 34.

[0038] When the snap-fit ​​block 33 is inserted into the tooth groove of the limiting gear 3, the rotation of the display body 11 remains fixed. When it is necessary to adjust the rotation of the display body 11, first disengage the tip 331 from the snap-fit ​​groove 34, and then rotate the display body 11. The display body 11 drives the mounting rod 13 to rotate, and the mounting rod 13 drives the limiting gear 3 to rotate through the limiting block 31 and the limiting groove 32.

[0039] Reference Figure 2 and Figure 5 The top surface of the fixed housing 1 has a control groove 41 that communicates with the snap-fit ​​groove 34. The fixed housing 1 is vertically slidably mounted with a control block 4 via the control groove 41. A reset block 42 is fixed to the side of the control block 4. A reset groove 43 is formed on the inner wall of the control groove 41. The reset block 42 slides vertically with the fixed housing 1 via the reset groove 43. A reset spring 44 is fixed to the top surface of the reset block 42. The end of the reset spring 44 away from the reset block 42 is fixedly connected to the inner wall of the reset groove 43. The top surface of the snap-fit ​​block 33 has a connecting groove 36 for inserting the control block 4. The inner wall of the connecting groove 36 away from the limiting gear 3 has an inclined surface 37. The bottom surface of the control block 4 has an inclined surface 45 for abutting against the inclined surface 37.

[0040] When the rotation of the display body 11 needs to be adjusted, press the control block 4 downwards. The control block 4 abuts against the inclined surface 37 and the inclined surface 45, thereby pushing the locking block 33 to move away from the limiting gear 3, so that the tip 331 disengages from the tooth groove of the limiting gear 3, so that the display body 11 can be manually rotated to a suitable angle. After the adjustment is completed, release the control block 4. The control block 4 moves upward and resets under the elastic force of the reset spring 44, releasing the limiting force on the locking block 33. The locking block 33 moves towards the limiting gear 3 under the elastic force of the locking spring 35, so that the tip 331 is re-inserted into the tooth groove of the limiting gear 3.

[0041] Reference Figure 3 and Figure 6 The back of the display screen body 11 has a storage groove 51. A storage rod 52 is rotatably mounted at the bottom of the storage groove 51, and a positioning rod 5 is sleeved on the outer periphery of the storage rod 52. A torsion spring 53 is sleeved on the outer periphery of the storage rod 52. One end of the torsion spring 53 is fixedly connected to the inner wall of the storage groove 51, and the other end of the torsion spring 53 is fixedly connected to the side of the positioning rod 5. When the positioning rod 5 is not needed, it fits against the inner wall of the storage groove 51 under the elastic force of the torsion spring 53. A connecting groove 54 is formed on the outer periphery of the mounting rod 13, and the end of the positioning rod 5 can be inserted into the connecting groove 54. Several connecting holes 55 are formed on the outer periphery of the mounting rod 13, which communicate with the connecting groove 54. The connecting holes 55 are evenly spaced along the length of the mounting rod 13. A plug rod 56 is inserted into the connecting hole 55, and a positioning hole 57 for inserting the plug rod 56 is formed on the side of the positioning rod 5.

[0042] Insert the positioning rod 5 into the connecting slot 54, and then rotate the tilt angle of the display body 11 to a suitable angle so that the positioning hole 57 is aligned with one of the connecting holes 55. Pass the positioning rod 5 through the connecting hole 55 and the positioning hole 57 to fix the tilt angle of the display body 11, so that the tilt angle is not easily changed when the display shakes.

[0043] The implementation principle of a multi-angle adjustable display screen according to an embodiment of this application is as follows: When the display screen body 11 is not needed, the display screen body 11 is located in the mounting groove 12. When the display screen body 11 needs to be used, the motor 27 is started. The motor 27 drives the height adjustment screw 2 to rotate, and the drive block 22 drives the mounting rod 13 to move upward, thereby adjusting the height of the display screen body 11. The display screen body 11 is hinged to the mounting rod 13, which can adjust the tilt angle of the display screen body 11 to accommodate drivers of different heights. Rotating the mounting rod 13 can adjust the direction of the display screen body 11 to facilitate viewing by the driver or passengers. The display screen body 11 can be adjusted at multiple angles, improving the flexibility of the display screen body 11 and enabling the display screen body 11 to provide an ideal viewing angle in any environment.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
