Problems solved by technology

The existing six-degree-of-freedom dynamic seat mechanical body has a single structural form, and the structure and layout mostly adopt the traditional Stewart structure. For example, the dynamic seat platform of the 4D cinema proposed in Chinese patent CN201220435815.9 is designed based on the concept of the Stewart platform. Its six lifting shafts form a V-shape with each other and are arranged under the seat; the mechanical platform of the commercial game motorized seat proposed in Chinese patent CN201120544720.6 also adopts the traditional Stewart platform layout, and six oil cylinders are arranged under the platform. The layout of the two kinds of dynamic seats has restrictions on the turning ability, so there is a problem of insufficient turning ability
[0004] In addition, although the degree of automation of the existing dynamic seats has been improved, their application places are limited to a certain extent. There are still few small dynamic seats suitable for home theaters and home computers. Chinese patent CN201320090263.7 proposes a PLC-based Controlled dynamic seats for 4D cinemas require a computer connected to a PLC controller to control the movement of the seats

Abstract

A six-freedom-degree series-parallel domestic dynamic seat comprises an engine base, a middle platform, a movable platform, a seat body, a control hardware part and six branches. The seat body is arranged on the movable platform, and the control hardware part is arranged on the engine base. The three RPS branches are connected to the engine base and the middle platform, one end of the linear drive moving pair in the three RPS branches is connected with the engine base through a rotating pair, the other end of the linear drive moving pair is connected with the middle platform through a composite spherical hinge, and the two ends of the three branches are evenly distributed on the engine base and the middle platform in a circumferential mode; the three SPR branches are connected with the middle platform and the movable platform, one end of the linear drive moving pair in the three SRP branches is connected with the middle platform through a composite spherical hinge, the other end of the linear drive moving pair is connected with the movable platform through a rotating pair, and the two ends of the three SRP branches are evenly distributed on the middle platform and the movable platform in a circumferential mode. The six-freedom-degree series-parallel domestic dynamic seat is easy to operate, high in rigidity, small in occupied area and high in rotation capacity, working space is large, and actions are sensitive.

Description

technical field [0001] The invention relates to a seat, in particular to a dynamic seat. Background technique [0002] Dynamic seats have been widely used in large-scale entertainment venues, game equipment, and 4D cinemas. However, due to their complicated operation and poor dynamic effects, the application places and crowds of dynamic seats are limited, and the progress of dynamic seats is limited. Influenced by the structure of the mechanical body, improving the dynamic effect of the dynamic seat and reducing its cost are the current development directions of the dynamic seat. [0003] Existing dynamic seats with few degrees of freedom, such as: a three-degree-of-freedom electric dynamic seat proposed in Chinese patent CN201220724362.1, three electric lifting mechanisms are arranged under the seat, and its rotation capacity is limited. The existing six-degree-of-freedom dynamic seat mechanical body has a single structural form, and the structure and layout mostly adopt t...
