Two -degree-of-freedom cradle head mechanism

Abstract

The invention relates to a cradle head, in particular to a two-degree-of-freedom cradle head mechanism. The aim of the invention is to provide a two-degree-of-freedom cradle head mechanism, which can transfer loads without being limited by motor loads. The two-degree-of-freedom cradle head mechanism comprise a base, a horizontal motor and a vertical motor, wherein the spindle of the vertical motor fixed below the base is coaxially jointed with a cable head seat capable of rotating horizontally above the base; a cable head is hinged above the cable head seat by two symmetric fulcra; the cable head has a reversed-U shape; the horizontal motor is fixed on one internal side wall; a pinion is arranged on the spindle B which penetreates the side wall of the cable head; the pinion is in meshed connection with a gear wheel fixed on the fulcra of the cable head seat; and the cable head is mainly used for fixing antennae and is an electrical cable head. In the mechanism, longitudinal load is applied onto the base with a smart structure, a motor shaft bears no axial forces, the structure is simplified and more compact, and the cost is reduced and the application range of the invention is enlarged.

Description

technical field [0001] The invention relates to a cloud platform, in particular to a two-degree-of-freedom platform mechanism. Background technique [0002] At present, a fixed platform with two degrees of freedom is needed in more and more places, for example: cameras in video surveillance systems that can be seen everywhere now need a fixed platform with two degrees of freedom, which can be used for fixed The installed camera can automatically, conveniently and quickly adjust the camera angle according to the needs, which is the function of the two-degree-of-freedom pan-tilt. Of course, it’s not just the fixing of the camera, there are many places that need a fixed two-degree-of-freedom gimbal, and a gimbal is essentially a mounting platform composed of two motors, which can rotate horizontally and swing vertically exercise. There are two types of pan / tilt: fixed pan / tilt and electric pan / tilt. The fixed pan / tilt is suitable for the situation where the adjustment range i...

Problems solved by technology

In terms of existing patent literature, the existing literature is to study the "two-degree-of-freedom platform", and its patent number is 200610018168.0. In this literature, only a controllable load platform is described, and although there is no specific text for load transmission Description, but it has also been expressed very clearly in the figure, the load is transmitted step by step through the shaft, gear and bearing, so the load of the motor will be very large, and the load level of the product will be limited, while for self-locking And the problem of positioning accuracy is not mentioned. The load capacity of the existing two-degree-of-freedom pan-tilt is an important indicator to measure the pan-tilt. The traditional two-degree-of-freedom pan-tilt design is often complicated in design and high in cost.
