Problems solved by technology

[0013] The price of materials with high heat-resistant temperature is higher than that of materials with low heat-resistant temperature, and the processing cost is also high
[0014] If the material cost and processing cost of the frame are high, the price of the head-up display device is high

Embodiment Construction

[0050] Embodiments of the present invention will be described below with reference to the drawings.

[0051] (Example)

[0052] First, through figure 1 , to describe the basic structure and basic functions of the head-up display device 10, through figure 2 , to illustrate the effect of external light, by image 3 with Figure 4 , the specific structure of the head-up display device 10 will be described.

[0053] Such as figure 1 As shown, the head-up display device 10 includes a first reflective mirror 11 , a second reflective mirror 12 , and a casing 30 that accommodates the first reflective mirror 11 and the second reflective mirror 12 . A light source 13 , a display 14 , a substrate 15 are also accommodated in the housing 30 . Between the first reflection mirror 11 and the second reflection mirror 12, an intersecting optical path is formed.

[0054] In addition, the first reflective mirror 11 is a concave mirror, which has a curvature (reciprocal of the radius) that m...

Abstract

The present invention addresses the problem of providing a head-up display device having a structure such that the procurement cost of a bezel can be suppressed. A bezel part (33) is integrally formedon a curved wall portion (38) of an upper cover (36). Since the upper cover (36) is a die-cast product, the curved wall part (38) can be manufactured by one-time casting (die-casting) with a through-hole (39) and the bezel part (33). Since the bezel part (33) is integral with the upper cover (36), it is possible to reduce the procurement cost of the bezel part (33) compared to when the bezel part(33) is a separate part. If the bezel is configured as a separate part having a high heatproof temperature, the procurement cost of the bezel increases. However, if the bezel part is formed integrally with the case simply by partially deforming the case, as described in the present invention, it is possible to reduce the procurement cost of the bezel part.

Description

technical field [0001] The present invention relates to head-up display devices that take sunlight into account. Background technique [0002] The driver of the vehicle looks forward through the windshield and drives while looking at the gauges on the mounting panel. That is, the gaze moves to the front and bottom instrument classes. If the gauges can be seen before looking ahead, there will be no movement of the line of sight, and an improvement in drivability can be expected. Based on this point of view, people have developed head-up display devices and put them into practical use (for example, refer to Patent Document 1( figure 1 )). [0003] As in Patent Document 1 figure 1 As shown, the image light emitted upward from the HUD display (2) (numbers in parentheses indicate the symbols described in Patent Document 1. The same below) hits the inner surface of the windshield (5) or is reflected , is imaged in front of the driver (paragraph 0012 of Patent Document 1). Wh...
