Torque amplifier for damper

Abstract

The invention provides a torque amplifier for a damper. A damper and a torque amplifier are positioned in an accommodating space inside a base of a seat body; a rotating shaft penetrates through one side of the accommodating space and is provided with a connection part; at least two accommodating slots which are communicated to the inner accommodating space are formed in the actuation part on the other side of the connection part; an annular tooth part penetrating into the accommodating space is arranged on one side of the connecting shaft of the torque amplifier, and at least two planet gears positioned in the accommodating slots are engaged on the annular tooth part; each planet gear is engaged on an annular tooth slot in the inner wall surface of the base; and an axial rod which is arranged in the perforation of a damping part of the damper in a penetrating manner is arranged in the center, on the opposite side of the annular tooth part, of the connecting shaft. When the rotating shaft rotates, the actuation part can be used for pushing the planet gears to engage and drive the annular tooth part, the connecting shaft can simultaneously rotate according to a preset gear ratio, and the connecting shaft is linked with the damping part, so that the damper can achieve the effect of steppless multiple torque amplification.

Description

technical field [0001] The present invention provides a damper torsion amplifier, in particular, a damper and a torsion amplifier are located inside the base of the seat body, and a rotating shaft is pierced on one side of the base, so that the torsion amplifier can be driven by the rotating shaft according to a predetermined gear. The specific rotation, supplemented by a damper, can achieve the effect of steplessly multiplying the torque. Background technique [0002] Press, nowadays many electronic devices (such as computer screen tripods, laptop screens, LCD monitors, etc.) The cover pivoted by the shaft assembly on the body can rotate stably, and the shaft assembly generally uses a damper to reduce its rotation speed to achieve the effect of slow opening and closing or slow down, so as to avoid excessive rotation of the cover. Direct impact on the body causes instant rebound injury, structural damage and noise problems. [0003] Furthermore, in order to provide suffici...

Problems solved by technology

[0003] Furthermore, in order to provide sufficient structural support for the cover, the rotating shaft assembly of the electronic device or daily necessities will use a damper with a large torque output, so that the cover has better structural stability when rotating, and different types of dampers There will be different structures and assembly methods, but the overall volume and space occupied by the existing high-torque output damper is relatively large, so that the space available for assembly of the rotating shaft assembly on electronic devices or daily necessities will be limited to a certain extent. If a damper with low torque output is used, it can improve the problems caused by occupying volume and space, but this kind of damper is limited to the size requirements, so the torque value of the damper is small, and in the case of insufficient assembly space Next, multiple dampers must be connected in series to achieve high torque output. This will increase the number of dampers and increase the cost. The problem that the dampers with low torque output must be connected in series is the key point for those engaged in this industry to redesign.
