Description

LCD Dual Axial Hinge

The utility model relates to a biaxial hinge of a liquid crystal display, in particular to a hinge capable of adjusting a degree of freedom of the liquid crystal display.

The disadvantages of traditional LCD hubs are:

For one, it only adjusts in a single axis. In terms of use, the adjustable degree of freedom is not enough, which does not meet the actual use conditions. Although there are liquid crystal display hubs with non-uniaxial adjustment, such as Taiwan Patent Publication No. 370237 discloses an improved liquid crystal display adjustment frame structure, although the adjustment frame structure is not only a single axial adjustment, but its volume is relatively small. It is large and takes up a lot of space. In today's situation where products tend to be thinner and smaller, there is still room for improvement in this type of design.

Another example is the similar design disclosed in Taiwan Patent Gazette No. 394406 and No. 387533, which has a more complex structure and more components. However, the achievable effect is not great, but the cost is greatly increased.

Second, the bonding surface between the hinge and the lock of the LCD display is too small to easily cause shaking. as well as,

Third, the wires connected to the liquid crystal display are often prone to falling off or generating noise due to rotation and pulling.

The main purpose of the utility model is to provide a two-degree-of-freedom adjustable liquid crystal display biaxial hinge.

The secondary purpose of the utility model is to provide a biaxial hinge of a liquid crystal display with locking holes arranged in a matrix, so as to increase the contact area with the display and reduce shaking.

Another object of the present invention is to provide a biaxial hinge of a liquid crystal display that uses a clip (CLIP) to fix the wires, so as to prevent the display from falling off or generating noise due to rotation and pulling.

In order to achieve the above purpose, the biaxial hinge of the liquid crystal display of the utility model is characterized in that it includes: a lower support frame, which is fixed at the desired predetermined position; a lower rotating bearing, one end of which is connected to the lower support frame so as to be relatively Rotating on the lower bearing frame; a support frame, one end of which is locked to the lower bearing frame, and the other end supports the lower rotating bearing; a connecting bracket, which is fixed to the other end of the lower rotating bearing; the upper rotating bearing; and an upper bearing The frame is connected to the connecting frame with the upper rotating bearing so as to be rotatable relative to the connecting frame.

Wherein the upper support frame includes a locking surface, and the locking surface has a matrix of 2×2 locking holes, and the locking holes can lock the liquid crystal display on the locking surface.

Preferably, the upper bracket includes a clip (CLIP), and the clip fixes the wires of the liquid crystal display on the upper bracket.

Adopt the above scheme of the utility model, the liquid crystal display biaxial hinge of the utility model and the lock pay bonding surface of the liquid crystal display are changed from the traditional linear arrangement lock pay hole to the matrix 2×2 arrange lock pay hole 621, can increase like this contact area to reduce shaking. The utility model liquid crystal display biaxial hub is easy to arrange the wires, and the wires can be fixed on the upper support frame by the snap-fitting piece. No direct force, so it is not easy to fall off, and it is not easy to produce abnormal sound due to the pulling of the wire. In addition, the connecting bracket and the lower rotating bearing are fixed together. When the LCD monitor is rotated left and right, the wire and the connecting bracket will not move relative to each other and produce friction. situation, thus extending the life of the wire.

In order to better understand the purpose, features and advantages of the utility model, the utility model will be described in detail below with the accompanying drawings.

A preferred embodiment of the present utility model will be described in detail below in conjunction with the accompanying drawings.

Please refer to Figure 1A and Figure 1B:

The liquid crystal display biaxial hinge of the utility model comprises: a lower bearing frame 1, a lower rotating bearing 2, a support frame 3, a connecting bearing frame 4, an upper rotating bearing 5 and an upper supporting frame 6.

The lower frame 1 is fixed at a desired predetermined position: one end of the lower rotating bearing 2 is connected to the lower frame 1 so as to be able to rotate relative to the lower frame 1;

One end of the support frame 3 is locked to the lower bearing frame 1, and the other end supports the lower rotating bearing 2;

The connecting bracket 4 is fixed on the other end of the lower rotary bearing 2; and

The upper frame 6 is connected to the connecting frame 4 with the upper rotating bearing 5 so as to be rotatable relative to the connecting frame 4 .

The upper support frame 6 includes a locking surface 62 , the locking surface 62 has a matrix of 2×2 locking holes 621 , and the locking holes 621 can lock the LCD 8 to the locking surface 62 .

Preferably, the upper frame 6 includes a clip (CLIP) 7 , the clip fixes the wires of the liquid crystal display 8 to the upper frame 6 .

Please refer to Figures 2A-2C;

The lower bracket 1 has a first protruding piece 11; the lower rotary bearing 2 has a first restricting structure 21, and the first restricting structure 21 and the first protruding piece 11 limit the rotation of the lower rotary bearing 2 within an angle .

See Figures 3A-3D:

The upper bracket 6 has a second protruding piece 61; the connecting bracket 4 has a second limiting structure 41, the second limiting structure 41 and the second protruding piece 61 limit the connecting bracket 4 to rotate within an angle .

To sum up, the biaxial hinge of the liquid crystal display of the utility model can perform biaxial rotation, and can rotate up, down, left, and right.

Up and down rotation: When the height of the upper rotating shaft is kept constant, the liquid crystal display 8 is fixed on the upper support frame 6 and the required angle is adjusted around the upper rotating shaft.

Left and right rotation: the lower bearing frame 1 and the support frame 3 do not move and other parts rotate left and right around the lower rotating bearing 2, and the connecting bearing frame 4 and the lower rotating bearing 2 are fixed together and do not move relative to each other.

The locking surface of the biaxial hinge of the liquid crystal display of the utility model and the liquid crystal display is changed from the traditional linear arrangement of the locking holes 621 to a matrix of 2×2 arrangement of the locking holes 621 to increase the contact area and reduce shaking.

The biaxial hinge of the liquid crystal display of the utility model is easy to arrange the wires, and the wires can be fixed on the upper support frame 6 by the clip (CLIP) 7. When the liquid crystal display rotates, the wires rotate together with the liquid crystal display 8 and the upper support frame 6, so that the wires The connector (CONNECTOR) connected with the liquid crystal display 8 is not directly stressed, so it is not easy to fall off, and it is not easy to produce abnormal sound due to wire pulling. In addition, the connecting bracket 4 and the lower rotating bearing 2 are fixed together, and the liquid crystal display 8 works When rotating left and right, the wire rod and the connecting bracket 4 do not move relative to each other to generate friction, so the wire rod can be protected to prolong its life.

The above are only preferred embodiments of the present utility model, but are not intended to limit the present utility model. Those familiar with the art can also make various equivalent changes and equivalent replacements without departing from the spirit of the present utility model. These equivalent changes and equivalent replacements should all be included in the patent protection scope of the present utility model.
