Screen fine-tuning device

Technical Field

The present invention relates to a screen fine adjustment device, and more particularly to a screen fine adjustment device with automatic tracking.

Background

The lcd panel rotation structure described in the application No. 534422 in taiwan is located on the top of the back plate and the support of the lcd panel, so that the lcd panel can be rotated by 360 degrees at most as required, and the lcd panel can tilt and rotate freely along with the manual force application direction of the user.

However, manual adjustment can only be roughly adjusted, and when the user is not convenient to move, it is difficult to manually adjust the screen 100. On the other hand, the adjustment method cannot automatically determine whether the user is located within the optimal viewing angle range θ, so as to adjust the screen at a proper time.

Therefore, how to eliminate the above-mentioned disadvantages is the difficult point to be solved by the present invention.

The driving mechanism comprises a motor controller, at least one motor and at least one shaft rod, wherein the at least one shaft rod is connected with the screen, and the motor controller controls the at least one motor to drive the at least one shaft rod to drive the screen to rotate.

Wherein the sensor is an image sensor.

Wherein, the plurality of support arms are respectively connected through a rotating shaft.

Wherein, the sensor is arranged on the screen or the bracket.

Therefore, the user can pull the support from the folding state to the unfolding state in a manual mode, the screen is enabled to be close to the user rapidly, the user is sensed through the sensor, the driving mechanism drives the screen to rotate slightly, the screen faces the user, the time-saving and convenient practical efficacy is achieved, the screen can be folded when not in use and does not occupy space, the angle fine-adjustment function can be achieved when in use, and the screen is adjusted to a comfortable viewing angle.

Detailed Description

In order to make it easy to understand the other features and advantages of the present invention and the efficacy achieved thereby, the present invention will be described in detail with reference to the accompanying drawings as follows:

referring to fig. 2, the present invention provides a screen fine-tuning device, which includes: a screen 1, a bracket 2 and a sensor 3.

The screen 1 is driven to rotate by a drive mechanism 11. Specifically, the driving mechanism 11 may include a motor controller, at least one motor and at least one shaft 111, the at least one shaft 111 is connected to the screen 1, and the motor controller is configured to control the at least one motor to drive the at least one shaft 111 to rotate the screen 1. For example, a first motor and a first shaft (as a horizontal rotation shaft of the screen 1, so that the screen 1 rotates up and down with the first shaft as an axis) can be used to drive the screen 1 to rotate up and down, and a second motor and a second shaft (as a vertical rotation shaft of the screen 1, so that the screen 1 rotates left and right with the second shaft as an axis) can be used to drive the screen 1 to rotate left and right, so that the screen has the functions of rotating up and down, left and right.

Referring to fig. 3 and 4, the support 2 is connected to the screen 1, the support 2 includes a plurality of arms 21 rotatably connected to each other, and the support 2 can be changed between a folded state and an unfolded state. Specifically, the plurality of arms 21 are rotatably connected to each other by a rotating shaft 211.

The sensor 3 is electrically connected to the driving mechanism 11. Specifically, the sensor 3 is used for sensing a user, the sensor 3 may be an image sensor for capturing an image of a face, and a face recognition technique may be used to recognize a position of the face according to a distance between eyebrows, eyes, noses, teeth, or mouths of the face, thereby determining a head rotation direction, which may be, for example, head-up, head-down, head-right, or head-left. Then, the sensor 3 transmits information such as the face position and the head rotation direction to the drive mechanism 11. The sensor 3 may be provided on the screen 1 or the stand 2.

Referring to fig. 5 and 6, in use, firstly, the user 4 can pull the bracket 2 from the folded state to the unfolded state by hand, so that the screen 1 is close to the user quickly, the sensor 3 senses the user, and the driving mechanism 11 drives the screen 1 to rotate slightly, so that the screen 1 faces the user, thereby achieving the practical effects of time saving and convenience.

For example, the first motor and the first shaft can be used as a horizontal rotation shaft of the screen 1, so that the screen 1 rotates up and down with the first shaft as an axis to drive the screen 1 to rotate up and down, and the angle between the screen 1 and the line of sight of the user is kept at 15-25 degrees (the eye position of the face can be identified by matching with the face recognition technology). The second motor and the second shaft rod can be used as the longitudinal rotating shaft of the screen 1, so that the screen 1 rotates left and right by taking the first shaft rod as the axis to drive the screen 1 to rotate left and right, and the screen 1 is enabled to rotate towards a user.

Therefore, the user can manually pull the support 2 from the folding state to the unfolding state to enable the screen 1 to be close to the user rapidly, the sensor 3 senses the user, the driving mechanism 11 drives the screen 1 to rotate slightly, the screen 1 faces the user, the time-saving and convenient practical efficacy is achieved, the screen can be folded without occupying space when not in use, the angle fine-adjusting function can be achieved when in use, and the screen 1 is adjusted to a comfortable viewing angle.

The above description is only a preferred embodiment of the present invention, and is not intended to limit the scope of the present invention; therefore, the equivalent shapes, structures or combinations of the components are all covered by the scope of the invention without departing from the spirit and scope of the invention.
