[0006] Furthermore, the connecting assembly includes a rotating shaft arranged radially and horizontally along the connecting assembly, the forearm and the rear arm are hinged together through the rotating shaft, the front end of the forearm is hinged to the ear seat, and the rear end of the rear arm is hinged to the base.

[0007] Furthermore, the front arm is sleeved on the middle part of the axial direction of the rotating shaft, and the rear arm includes a group of symmetrically arranged rotating arms, and the rotating arms are respectively sleeved on both ends of the axial direction of the rotating shaft.

[0008] Furthermore, the base includes at least two support seats that are separated from each other, and each of the support seats is hinged to at least one support arm of each of the connecting components.

[0009] Further, the resistance provided by the damping element arranged in the upper support arm is smaller than the resistance provided by the damping element arranged in the lower support arm.

[0010] Furthermore, the support arm is hinged to the ear seat with the radial direction of the support arm as the rotation center, and the rotation direction of each support arm and the ear seat is consistent.

[0011] Furthermore, the distance between each of the support arms and the hinged joint of the ear seat is adjustable.

[0012] The display screen bracket using the above technical solution of the utility model has the following effects:

[0013] The utility model realizes the self-rotation of the display screen around its supporting axis X-axis by providing a turntable.

[0019] The specific implementation of the present invention is described in detail below. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0020] In the present invention, unless otherwise stated, the directional words used, such as "upper" and "lower", generally refer to the direction in the assembled state. "Inside" and "outside" refer to the inside and outside relative to the contour of each component. It should be explained that in the present invention, the X-axis is the left-right lateral direction, the Y-axis is the direction in the horizontal plane perpendicular to the X-axis, and the Z-axis is the direction perpendicular to the horizontal plane.

[0021] The utility model provides a display screen bracket, comprising a base 7, a mounting head for mounting a display screen, and a connecting assembly connected between the base 7 and the mounting head, wherein the mounting head comprises an interface 1 connected to the display screen, a turntable 2, and an ear seat 5, wherein the bottom of the turntable 2 is rotatably connected to the interface 1, the top of the turntable 2 is fixed to the ear seat 5, the ear seat 5 is hinged at one end of the connecting assembly, and the other end of the connecting assembly is hinged on the base 7. The connecting assembly comprises a set of support arms arranged in an upper and lower mirror image, wherein the support arms comprise a rotatably connected forearm 3 and a rear arm 6. The connecting assembly further comprises a damping element, which is arranged at the rotatable connection between the forearm 3 and the rear arm 6 and at the hinge between the connecting assembly and the base 7.

[0022] The utility model realizes the self-rotation of the display screen around its supporting axis X-axis by setting a turntable 2. By setting a connection component that realizes distance adjustment by rotation, the display screen can be moved along its supporting direction X-axis. At the same time, by setting an ear seat 5 of a hinged support arm, the display screen can be flipped around the Y-axis when the upper and lower support arms are used to adjust the distance between each other. At the same time, combined with the hinge on the base 7, the connection component can swing around the base 7, thereby realizing the movement of the display screen along the Z-axis. Up to 4 degrees of freedom can be used to adjust the position of the display screen, which is more flexible and more applicable, meeting the needs of students of different heights. Even students with insufficient height can flip the display screen downward along the Y-axis to achieve the purpose of seeing the screen clearly. At the same time, considering that the display screen adopts a wall-mounted installation method and is supported from the side wall of the display screen, it is necessary to strengthen the stability of the display screen support, and the support method using upper and lower double support arms is also more stable.

[0023] In order to constrain the rotation direction of the support arm, make the rotation more stable, and give full play to the damping effect of the damping element, preferably, the connecting assembly includes a rotating shaft 4 arranged radially and horizontally along the connecting assembly. The front arm 3 and the rear arm 6 are hinged together through the rotating shaft 4. The front end of the front arm 3 is hinged to the ear seat 5. The rear end of the rear arm 6 is hinged to the base 7.

[0024] To further improve the stability of the connection assembly support. Preferably, the front arm 3 is sleeved in the middle of the axial direction of the shaft, and the rear arm 6 includes a group of symmetrically arranged rotating arms, which are respectively sleeved at both ends of the axial direction of the shaft. The rear arm 6 with a double rotating arm arrangement not only makes the front arm 3 and the shaft 4 more firmly fixed, but also plays a role in sharing stress at the rear arm 6 where stress is concentrated, thereby improving the stability and fatigue strength of the support arm support, increasing the service life of the bracket, avoiding the need for timely maintenance during use, and also improving safety and reducing costs.

[0025] In order to make the base 7 support more stable, the upper and lower support arms are connected as a whole. Preferably, the base 7 includes at least two support seats that are separated and each support seat is hinged to at least one support arm of each connecting assembly.

[0026] In order to make it more convenient to adjust the display screen to rotate around the Y axis, preferably, the resistance provided by the damping element arranged in the upper support arm is smaller than the resistance provided by the damping element arranged in the lower support arm. By making the damping forces of the upper and lower support arms different, the lower support arm is used as a fulcrum during rotation, and the lower support arm can also play the role of supporting the weight of the display screen.

[0027] In order to make the display screen rotate more reliably along the Y-axis direction, preferably, the support arm is hinged to the ear seat 5 with the radial direction of the support arm as the rotation center, and the rotation directions of the hinges of each support arm and the ear seat 5 are consistent.

[0028] In order to make the display screen rotate more flexibly and adjustable along the Y axis, preferably, the distance between each support arm and the hinge of the ear seat 5 is adjustable. It should be noted that the adjustable distance in the technical solution can be achieved in many ways, such as ear seats 5 of different lengths, a telescopic mechanism between the ear seat 5 and the hinge of the support arm, etc.

[0029] The preferred embodiments of the present invention are described in detail above. However, the present invention is not limited to the specific details in the above embodiments. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications, and these simple modifications all belong to the protection scope of the present invention.

[0030] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.

[0031] In addition, various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
