Television stand

Abstract

The invention discloses a television stand capable of adjusting a visual angle, which comprises a base, an intermediate, a television support, a longitudinal angle adjuster, a horizontal angle adjuster and a control circuit board, wherein the lower part of the base is provided with a cantilever stretching forwards, the front end of the protracting cantilever is provided with a cantilever hinge support, the intermediate comprises a framework and a pin roll, the pin roll is arranged at the front end of the framework, the lower part of the front end of the framework is provided with a framework hinge support, the framework hinge support at the lower part of the front end of the framework is articulated with the cantilever hinge support at the front end of the cantilever, the longitudinal angle adjuster comprises a motor, a crank and a connecting rod, the connecting rod is articulated with the base, the horizontal angle adjuster comprises a motor, a swing sleeve, a crank and a connecting rod, the connecting rod is articulated with the swing sleeve, the swing sleeve is articulated with the framework of the intermediate through the pin roll, and the television support is fixed on the swing sleeve. The invention has the advantages of reasonable stress, simple structure, small volume, attractive appearance, convenient assembly and easy batch production.

Description

technical field [0001] The invention relates to a TV stand, in particular to a TV stand with an adjustable viewing angle. Background technique [0002] With the popularity of LCD TVs and plasma TVs, people have higher and higher requirements for TV stands with adjustable viewing angles. A TV stand with an adjustable viewing angle generally includes an up and down angle adjuster and a horizontal angle adjuster to facilitate adjustment of the viewing angle of the TV stand. The existing TV stand with adjustable viewing angle has the following disadvantages: the hinge point is not set properly, there is a certain distance between the center of gravity and the hinge point, there is a gravity moment, and the motor of the angle adjuster needs to overcome the TV bracket and the TV frame. The gravity moment of the machine can drive the TV bracket to rotate, the force is unreasonable, the motor power of the angle adjuster must be very large, otherwise it will be difficult to drive th...

Problems solved by technology

The existing TV stand with adjustable viewing angle has the following disadvantages: the hinge point is not properly set, there is a certain distance between the center of gravity and the hinge point, there is a moment of gravity, and the motor of the angle adjuster needs to overcome the TV stand and the TV frame. The gravity moment of the machine can drive the TV bracket to rotate, the force is unreasonable, the motor power of the angle adjuster must be very large, otherwise it will be difficult to drive the TV stand with the TV installed; if a high-power motor is used, it will inevitably take up a lot of space and affect Decorative effect, limiting wide application
