[0039] Please refer to Figure 1-Figure 2 The present invention discloses a screen adjustment device, including a first carrier plate 10, a second carrier plate 30 and a motion assembly 50, one side of the first carrier plate 10 is suitable for connecting with a screen 60; the second carrier plate 30 is slidably connected to the first carrier plate 10, one of the first carrier plate 10 and the second carrier plate 30 is provided with a first guide groove 31, and the other is provided with a guide column 13 matching the first guide groove 31; the motion assembly 50 is connected to the first carrier plate 10 to drive the first carrier plate 10 to move along the direction defined by the first guide groove 31.

[0040] It is understandable that the connection between the first carrier plate 10 and the screen 60 can be a fixed connection or a detachable connection, and the detachable connection can be in the form of a snap connection, a buckle connection, a magnetic connection, etc. The first carrier plate 10 and the screen 60 are preferably detachably mounted, which is convenient for installing and replacing the screen 60. For example, when the screen 60 is a car screen, if the car screen fails, a black screen or freezes, or if the passenger's mobile phone screen is needed for displaying navigation, the car screen can be removed and the mobile phone display screen can be installed. The screen 60 involved in the present invention can be, but is not limited to, a car display screen, a car screen, a pad display, a mobile phone display, etc.

[0041] It should be understood that the sliding connection between the second supporting plate 30 and the first supporting plate 10 refers to the ability of the second supporting plate 30 to slide relative to the first supporting plate 10, and also includes the ability of the first supporting plate 10 to slide relative to the second supporting plate 30. Specifically, the sliding paths of the two supporting plates are restricted by the first guide grooves 31 and the guide posts 13. In one embodiment, the first supporting plate 10 is provided with the first guide grooves 31, and the second supporting plate 30 is provided with the guide posts 13 that match the first guide grooves 31; in another embodiment, the second supporting plate 30 is provided with the first guide grooves 31, and the first supporting plate 10 is provided with the guide posts 13 that match the first guide grooves 31.

[0042] In the technical solution of the present invention, the motion component 50 drives the first carrier plate 10 to move along the direction limited by the first guide groove 31. With the cooperation of the first guide groove 31 and the guide column 13, the angle adjustment of the screen 60 is realized, such as left and right angle adjustment, front and back movement, and left and right rotation. The overall structure operates stably, thereby improving customer experience.

[0043] Please refer to Figure 3 In order to improve the stability of the screen 60 installation, the first supporting plate 10 is bent and extended at one end close to the screen 60 to form a mounting portion 15 (such as Figure 2 For ease of use, the side of the mounting portion 15 close to the screen 60 is tilted downward at a certain angle, so that the screen 60 is tilted at a certain angle to the horizontal. The angle can be designed according to different needs and is not limited here.

[0044] Please refer to Figure 4 The first carrier plate 10 is provided with a second guide groove 11, and the output end of the motion component 50 is provided with a slider 40 (such as Figure 7 (as shown). The motion assembly 50 drives the slider 40 along the second guide slot 11. This, in conjunction with the first guide slot 31 and the guide post 13, drives the first carrier plate 10 to adjust its angle. Furthermore, the second guide slot 11 extends along the length direction K1 of the first carrier plate 10. At this point, the motion assembly 50 drives the slider 40 within the second guide slot 11 along the width direction of the first carrier plate 10. This, in conjunction with the first guide slot 31 and the guide post 13, drives the first carrier plate 10 to adjust its angle left and right, move forward and backward, and rotate left and right. It is worth noting that during this movement, the left and right angle adjustment, forward and backward movement, and left and right rotation occur simultaneously.

[0045] Please refer to Figure 5The first guide slot 31 includes a first guide portion 311 and a second guide portion 313. The first guide portion 311 and the second guide portion 313 are symmetrically arranged along the length direction K1 of the first carrier plate 10 to ensure stable and accurate angle adjustment. In this embodiment, the first guide portion 311 and the second guide portion 313 are located on the second carrier plate 30. The first carrier plate 10 is provided with guide posts 13 that respectively adapt to the first guide portion 311 and the second guide portion 313. Furthermore, the first guide portion 311 includes a first guide slot 312 and a second guide slot 314. The first guide slot 312 has an opposing first end 3121 and a second end 3123. The second guide slot 314 has an opposing third end 3141 and a fourth end 3143. The second end 3123 of the first guide slot 312 is connected to the third end 3141 of the second guide slot 314. The first guide slot 312 and the second guide slot 314 are arranged at an angle. For example, the angle between the first guide slot 312 and the second guide slot 314 can be, but is not limited to, 20 degrees, 30 degrees, 40 degrees, 50 degrees, or 60 degrees. The second end 3123 is connected to the third end 3141 to connect the first guide slot 312 and the second guide slot 314, facilitating movement of the guide post 13. The first end 3121 and the fourth end 3143 may or may not be aligned vertically. This design limits the travel of the guide post 13, thereby enabling adjustment of the screen 60 angle. Therefore, the specific travel can be determined based on actual needs. Furthermore, the first guide slot 312 and the second guide slot 314 have different inclinations relative to the second guide slot 11 to facilitate left-right angle adjustment. In a preferred embodiment, the length of the first guide slot 312 is greater than that of the second guide slot 314. In this embodiment, the first guide slot 312 is positioned away from the center of the second support plate 30, while the second guide slot 314 is positioned closer to the center. This reduces the time it takes to adjust the screen 60 to the desired position and improves operational efficiency, but the present invention is not limited to this. In some embodiments, the second guide slot 314 is positioned away from the center of the second support plate 30, while the first guide slot 312 is positioned closer to the center of the second support plate 30. It should be understood that the description of the second guide slot 11 can refer to the description of the first guide slot 31 and will not be elaborated upon here.

[0046] Please refer to Figure 2 and Figure 6The screen 60 adjustment device of the present invention also includes a third supporting plate 20, and the first supporting plate 10 is located between the second supporting plate 30 and the third supporting plate 20, wherein the third supporting plate 20 is provided with a clearance groove 21 for accommodating the slider 40 to pass through. In this embodiment, the motion component 50 is arranged on the side of the third supporting plate 20 away from the first supporting plate 10, and the motion component 50 drives the slider 40 to move, and the clearance groove 21 provides it with an air escape position. Furthermore, the clearance groove 21 extends along the length direction K2 of the third supporting plate 20. For example, the clearance groove 21 can be a strip groove or an elliptical groove, but is not limited thereto. It can be understood that the second supporting plate 30 and the third supporting plate 20 are connected by fasteners such as but not limited to screws and bolts.

[0047] Please refer to Figure 7-Figure 8 The motion assembly 50 includes a screw rod 51, a transmission portion 53 sleeved on the screw rod 51, and a driving portion 55 connected to the screw rod 51. The transmission portion 53 is connected to the slider 40 via a connecting portion 57. The transmission portion 53 sleeved on the screw rod 51 can be threadedly engaged with the screw rod 51. Since the driving portion 55 can drive the screw rod 51 to rotate around its axis, the screw rod 51 will drive the transmission portion 53 engaged therewith to move laterally along the axis of the screw rod 51, and the transmission portion 53 will drive the connecting portion 57 to move in conjunction with it. It can be understood that the adjustment angle of the screen 60 is related to the length of the screw rod 51. The specific length can be determined according to the actual design and is not limited here.

[0048] Please refer to Figure 7-Figure 8 The motion assembly 50 further includes a guide bar 59 arranged parallel to the screw rod 51. In this embodiment, the guide bar 59 and the screw rod 51 are mounted on the third carrier plate 20 via two fixing brackets 58. The driving unit 55 is mounted on one of the fixing brackets 58. Because the transmission unit 53 is sleeved on the guide bar 59 and the screw rod 51, the transmission unit 53 can move stably. Furthermore, the driving unit 55 includes a driving motor 551, a driving wheel 553, a driven wheel 557, and a conveyor belt 555 wound around the driving wheel 553 and the driven wheel 557. The driving wheel 553 is connected to the driving motor 551, and the driven wheel 557 is connected to the screw rod 51. The driving motor 551 drives the driving wheel 553 to rotate, which in turn drives the driven wheel 557 to rotate via the conveyor belt 555. Because the driven wheel 557 is connected to the screw rod 51, the screw rod 51 is linked to the driving wheel 553 and rotates around its axis.

[0049] The adjustment device of the present invention also includes a control unit, which controls the operation of the drive motor 551 to achieve automatic adjustment of the angle of the adjustment screen 60. In one embodiment, the control unit can control the start and stop of the drive motor 551, for example, by being connected to the control unit through a human-computer interaction interface. As needed, the adjustment is performed through the human-computer interaction interface. If the screen 60 needs to be tilted 10 degrees to the left, the adjustment angle option and adjustment direction are selected in the human-computer interaction interface, and the adjustment angle parameter is input as 10 degrees. The control system can also be controlled and operated through a mobile phone APP, thereby achieving automation and precise control. That is, the user can control and adjust the posture of the screen 60 through the control unit according to their needs to satisfy the user's comfortable use experience from their own perspective. The posture of the screen 60 includes but is not limited to the position of the screen 60 (the screen 60 moves forward and backward, left and right).

[0050] It is understandable that currently a family may only have one car, but there may be three people driving it. Different family members need to adjust the vehicle's screen 60 when driving. Whether manually adjusting the screen 60 or using the control icons (physical buttons or virtual buttons) on the screen 60, the driver needs to slowly adjust the position and angle of the screen 60 after getting in the car. The control unit of the present invention is equipped with a memory unit, and the adjustment configurations of different drivers are stored in the memory unit. When the driver uses the memory mode, he only needs to rotate the corresponding driver to automatically call the corresponding configuration information, which can achieve one-click adjustment and improve the driver's experience. The co-pilot or other passengers can also call the corresponding configuration settings, which greatly improves the user experience.

[0051] In another embodiment, a driver may encounter changes in lighting while driving. For example, after turning a corner, the light intensity increases, resulting in severe glare on screen 60, necessitating adjustment of the in-vehicle screen 60. Manually adjusting the angle of screen 60 by operating the trigger button on the display screen in this situation can significantly increase the driver's safety. The control unit of the present invention is configured to directly control the adjustment device to adjust screen 60 via the in-vehicle voice control system. The in-vehicle voice control system pre-configures a mapping relationship between voice signals and voice control commands, determines the voice control command corresponding to the current voice signal, such as "forward, backward, left, right, 10 degrees left, 10 degrees right, etc." The control unit controls the adjustment device to adjust screen 60 based on the voice control command corresponding to the current voice signal. The driver can adjust the angle of screen 60 without removing their hands from the steering wheel during the entire adjustment process. It should be understood that the mapping relationship between voice signals and voice control commands in the present invention can be modified based on the driver's preferences. For example, "forward" could be changed to "front," which is more concise and convenient, further enhancing the driver's user experience. The co-pilot or other passengers can also adjust the screen 60 by controlling the adjustment device through voice. It should be understood that the driver's adjustment priority is higher than that of the co-pilot or other passengers, which greatly improves the user experience.

[0052] In another embodiment, the control unit of the present invention can automatically control the adjustment device to adjust the screen 60 based on the angle of the screen 60 and the light reflection angle of the screen 60. For example, when the high beam of the vehicle behind is reflected by the screen 60 and interferes with the driver's vision, the adjustment device will be controlled to adjust the screen 60. This allows the driver to obtain a good viewing experience without having to manually adjust the screen 60, greatly improving the user experience and enhancing the driver's driving safety.

[0053] In another embodiment, the control unit of the present invention can control the adjustment device to adjust screen 60 based on real-time detection of the driver's eyes and the direction of their gaze. It should be understood that occupants of a vehicle often adjust their sitting posture, and the viewing experience of screen 60 will also change accordingly. In this embodiment of the present invention, the angle and position of screen 60 can be automatically adjusted based on the direction of the driver's gaze identified by the camera device to provide the driver with a good viewing experience, eliminating the need for manual adjustment of screen 60. This greatly improves the user experience and enhances the driver's driving safety.

[0054] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention are still within the scope of the present invention.
