Problems solved by technology

[0007] In conventional vehicle display devices, as the size of the display increases, etc., the driver's rear field of view generated by the interior mirror is often blocked. In addition, for some reason, when the display is expanded to a larger viewing angle, the display enters the driver's line of sight. At this time, there is a problem that the safety countermeasure of turning off the display cannot be automatically taken because there is no detection unit that detects that the viewing angle is greater than the viewing angle.

Embodiment Construction

[0021] In order to explain the present invention in more detail, the best mode for carrying out the present invention will be described below with reference to the accompanying drawings. Parts with the same components and functions are denoted by the same reference numerals.

[0022] Embodiment 1

[0023] Figure 1 to Figure 3 and Figure 4 In (a), the display 1 is made in the shape of a rectangular plate, and the rotating shaft 3 integrated with the display 1 is used as a fulcrum to be rotatable. The shaft 3 is supported by a shaft holder 4 as a supporting unit. The rotating shaft 3 protrudes concentrically from one end of the display 1, and also forms the same supporting structure as that on the illustrated side on the rear side perpendicular to the paper surface of each drawing. The shaft holder 4 is fixed to a base plate 16 attached to the ceiling of the vehicle compartment.

[0024] Figure 1 to Figure 3 The display 1 indicated by the middle solid line is in an unfo...

Abstract

The present invention provides a display opening / closing angle detection mechanism comprising a display (1) which is installed on the ceiling of a vehicle and rotated about a rotating shaft (3) in opening / closing directions integrally with the rotating shaft, a support means (4) supporting the rotating shaft (3), a means (18) vertically displacing the rotating shaft relative to the support means according to the rotation of the display, a rotating body vertically displaced and rotated integrally with the rotating shaft, a lever (9) movably pushed by a recessed / projected part at multiple rotating positions of the rotating body, and a switch (14) operated according to the operation of the lever.

Description

technical field [0001] The present invention relates to a display opening / closing angle detection mechanism for detecting the opening / closing angle of a display mounted on the roof of a vehicle and capable of opening and closing so that it is unfolded during use and closed during storage, and controls the display. Background technique [0002] A structure is known in which a video display as a display unit is mounted openably and closably on the ceiling of a vehicle compartment (for example, refer to Patent Document 1). In the relevant prior art, a rectangular display is connected to a bracket through a hinge, and the support structure is rotatable around a fixed fulcrum. The screen of the display is in a closed state along the ceiling when stored, and the screen is shifted to a so-called unfolded state that is substantially close to a vertical state for the convenience of viewers during use. In this viewing state, since the display occupies a space substantially from the f...
