the display assembly 200 comprises an upper screen assembly 50, a reflector assembly 60 and a rear screen assembly 70 which are fixedly arranged with each other, wherein the reflector assembly 60 comprises a semi-reflecting mirror 61, the semi-reflecting mirror 61 is arranged to incline forwards from top to bottom, the rear screen assembly 70 is arranged behind the semi-reflecting mirror 61, and the upper screen assembly 50 is arranged above the semi-reflecting mirror 61;
the display assembly 200 is fixedly connected with the rear case 20, and the rest of the display assembly 200 except the part fixedly connected with the rear case 20 is disposed in a non-contact manner with respect to the housing 100.
In this embodiment, the housing 100 is used to form a relatively closed protective structure for the display assembly 200, wherein the rear housing 20 is the primary support structure; the light shield 10 serves to cover the front side of the display assembly 200, thereby forming the above-described protective structure in cooperation with the rear case 20. The driver can observe the meter information displayed on the instrument panel of the automobile through the opening 11 of the light shield 10. It will be appreciated that in the cab of the vehicle, if excessive ambient light is applied to the display screen of the dashboard of the vehicle, reflected light will be generated which will cause the information to be displayed indistinctly, and the light shield 10 is used to shield such a portion of the ambient light to ensure the reliability of the information display of the dashboard of the vehicle. Since the light shield 10 has a relatively complicated shape and is an exterior part, the light shield 10 is generally formed by splicing a plurality of parts, and the prior manufacturing process of the component parts of the light shield 10 is preferably an injection molding process.
The upper screen assembly 50 is disposed in a non-contacting relationship with the light shield 10, i.e., the upper screen assembly 50 can be swung relative to the light shield 10 without colliding with the light shield 10. Preferably, in order to achieve a compact design and reduce the volume of the product, referring to fig. 4 and 5, a small gap is formed between the lower frame 53 of the upper screen assembly 50 and the top wall 141 of the light shield 10, so as to prevent collision and reduce dust entering the inner cavity of the light shield 10. Similarly, the mirror assembly 60 is disposed in non-contact with the housing 100, meaning that gaps or larger cavities are formed between the mirror assembly 60 and the light shield 10, and between the mirror and the rear housing 20.
It is understood that, in order to form a 3D display effect, the half mirror 61 serves to transmit a first image projected forward of the rear screen assembly 70 and to reflect a second image projected downward of the upper screen assembly 50 forward; forming a predetermined space between the real image of the first image and the virtual image of the second image to combine to form a 3D display effect;
in order to achieve both the display effect and the cost reduction of the dashboard of the automobile, the display screens of the upper screen assembly 50 and the rear screen assembly 70 are preferably segment code screens or TFT display screens.

In a particular implementation of the method of the utility model,
the half mirror 61 has both reflectivity and transmissivity with respect to light, i.e., semi-transmissivity and semi-reflectivity. The half mirror 61 is typically a glass-coated member. The display screen of the top screen assembly 50 and the display screen of the rear screen assembly 70 are generally symmetrical about the half mirror 61, but for better naked-eye 3D display, one of the two display screens may also be slightly off the symmetrical position, for example, the angle between the rear code-breaking screen and the half mirror 61 is 45 °, and the angle between the code-breaking screen and the support of the half mirror 61 is 47 °.
In the instrument panel of the utility model, the display assembly 200 is fixedly connected with the rear shell 20 as a whole, so that even if the assembly precision between the light shield 10 and the rear shell 20 is poor, the position relation among the upper screen assembly 50, the half mirror 61 and the rear screen assembly 70 in the display assembly 200 is not influenced, namely, the assembly error is not transmitted to the position precision among the upper screen assembly 50, the half mirror 61 and the rear screen assembly 70, thereby ensuring higher initial assembly quality. Further, the display assembly 200 is fixedly connected to the rear case 20 only through the upper screen assembly 50, and the components of the display assembly 200 are fixedly disposed to each other, so that even if the display assembly 200 shakes with respect to the rear case 20 in a vibration environment, the 3D display effect of the dashboard of the vehicle is not affected. Therefore, the automobile instrument panel is easier to ensure the assembly quality and can keep a stable 3D display effect in a vibration environment.
Further, the light shield 10 includes an opening 11, a light shield 12 and a light guide tube 13, the opening 11 is annular, and the light shield 12 extends backward from the upper edge of the opening 11; the light guide tube 13 is formed by extending backwards from the inner edge of the opening part 11; a top wall 141 opposite to the light shielding part 12 is formed on the top of the light guide cylinder 13, and a window 142 is arranged on the top wall 141;

In this embodiment, the housing of the top screen assembly 50 is provided as several separate parts, so that more complex inner cavities can be conveniently combined, and the assembly of the internal components of the top screen assembly 50 is facilitated. Since the upper cover 51 is the closest part to the guide plate 23, the provision of the first lug 511 on the upper surface of the upper cover 51 facilitates the simplification of the structure while ensuring the connection. Specifically, the upper cover 51 may be formed by an injection molding process, and the first lug 511 is integrally formed with the upper cover 51.
Since the upper display screen 54 is disposed toward the half mirror 61 below, the risk of falling off is greater than that of the rear display screen 73 arranged in the vertical direction. The base 52 is further divided into a middle frame 52 and a lower frame 53, so that the upper display screen 54 can be limited, and the upper display screen 54 is prevented from falling off. The first sealing ring 56 is disposed between the middle frame 52 and the upper display 54 to prevent moisture and dust from entering the light guide cavity between the upper circuit board 55 and the upper display 54.
