一种投影系统
摘要：
一种投影系统，涉及显示技术领域，包括投影单元(2)、屏幕单元(1)、外框机架(4)以及支撑结构组件(3)，屏幕单元(1)用于呈现投影单元(2)投影出的画面，外框机架(4)用于固定投影单元(2)和支撑结构组件(3)，支撑结构组件(3)用于将屏幕单元(1)与外框机架(4)固定连接，支撑结构组件(3)位于屏幕单元(1)的入光侧，支撑结构组件(3)包括透光部(31)和至少一个连接部(32)，透光部(31)与屏幕单元(1)固定连接，透光部(31)用于使投影单元(2)发出照射在透光部(31)上的光线透过；至少一个连接部(32)位于投影单元(2)发射光线的传播路径之外，至少一个连接部(32)用于固定连接透光部(31)与外框机架(4)。这种投影系统中，支撑结构组件(3)不会对投影单元(2)发射的光线进行遮挡，使投影系统具有较好的显示质量。
摘要（英）：

A projection system, relating to the technical field of display, comprising a projection unit (2), a screen unit (1), an outer frame (4) and a supporting structure module (3), the screen unit (1) being for providing a screen for the projection unit (2) to project on, the outer frame (4) being for fixing the projection unit (2) and the supporting structure module (3), and the supporting structure module (3) being for fixedly connecting the screen unit (1) to the outer frame (4). The supporting structure module (3) is disposed at a light-incident side of the screen unit (1). The supporting structure module (3) comprises a light-transmitting portion (31) and at least one connection portion (32). The light-transmitting portion (31) is fixedly connected to the screen unit (1). The light-transmitting portion (31) is for transmitting a light ray emitted by the projection unit (2) and incident on the light-transmitting portion (31). At least one connection portion (32) is disposed outside of apropagation path of a light ray emitted by the projection unit (2). At least one connection portion (32) is for fixedly connecting the light-transmitting portion (31) and the outer frame (4). In theprojection system, the supporting structure module (3) will not block a light ray emitted by the projection unit (2), enabling the projection system to have a good display quality.
