Embodiment Construction

[0029] Below in conjunction with specific examples, further illustrate content of the present invention.

[0030] see Figure 1~3 , is a schematic diagram of the base structure of the embodiment of the present invention, including a chassis 1 and three driving cylinders arranged in an isosceles triangle on the chassis 1. The bottoms of the three driving cylinders are connected to the chassis 1 through universal rotatable joints, and further the three The top of the first driving cylinder is universally rotatably connected with the chair frame. Specifically, the three driving cylinders include a front first driving cylinder 21, a rear first driving cylinder 22 and a rear second driving cylinder 23, the front first driving cylinder 21 is located at the apex of the isosceles triangle, and the rear first driving cylinder 22 and the rear second drive cylinder 23 are located at the two ends of the base of the isosceles triangle, the front first drive cylinder 21 is arranged on one ...

Abstract

The invention relates to a three-degree-of-freedom base and a 4D seat applying the same. The base comprises a chassis, a seat frame and a plurality of driving cylinders for connecting the chassis and the seat frame, wherein the driving cylinders are three driving cylinders which are distributed in an isosceles-triangle manner; each driving cylinder is connected with the chassis and the seat frame respectively by two ends of a universal and rotatable joint; the base also comprises at least one balance frame which is connected with the chassis and the seat frame by the two ends of a small-angle rotatable joint; and the 4D seat applying the base is also provided with a seat with an internal special-effect device on the chassis. The invention has the advantages that the traditional basic structure with the chassis, the seat frame and the driving cylinders is still used, three driving cylinders and two balance frames are used, so that multi-degree-of-freedom movement is realized, and the cost for driving, control and manufacture and cost for power energy are reduced; and the mechanical space is greatly saved, so that components needing to be provided with control equipment are integrated into a platform, and space support is provided for integration of a product.

Description

technical field [0001] The invention relates to a base, in particular to a three-degree-of-freedom base and a 4D seat using the same. Background technique [0002] 4D theater seats are technically mature and widely used. Traditional 4D seats usually need five drive cylinders to realize the reclining, left and right swing, and overall lifting of the seat, or four drive cylinders to realize the seat movement. Its forward and backward tilt, overall lifting, its movement lies in front and rear pitching, rising and falling; after upgrading, fast rising and slow rising, fast falling and slow falling are added. With the competition in the market, 4D cinema seats urgently need a new type of motion to meet the needs of the market. Contents of the invention [0003] In order to solve the above-mentioned problems of low control precision of the 4D cinema and failure of each equipment and its components to be scrapped according to their service life, the present invention proposes a ...
