In other embodiments, the sliding interface structure (22a, 22b, 22c) may be a ball, the sliding structure (91a, 91b, 91c) may be a rolling interface surface, and the like.
In use, the half mirror 61 is arranged to transmit a first image projected forwardly of the rear screen assembly 70 and to reflect a second image projected downwardly of the upper screen assembly 50 forwardly; 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. It will be appreciated that, in order to project the first image forwardly, the display screen of the rear screen assembly 70 is generally disposed forwardly; similarly, to project the second image downward, the display screen of the upper screen assembly 50 is disposed downward. In a particular implementation of the method of the utility model,

The display screen and the half mirror 61 of the rear screen assembly 70 are both reflective and transmissive to light, i.e., transflective. 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-symmetrical, for example, the angle between the rear display screen 73 and the half mirror 61 is 45 ° and the angle between the top display screen 54 and the support of the half mirror 61 is 47 °.
When the automobile instrument panel is assembled, the plurality of sliding structures (91a, 91b, 91c) on the back support 90 are matched with the plurality of sliding butt-joint structures (22a, 22b, 22c) on the rear shell 20, and the back support 90 is fixedly arranged on the back of the rear screen assembly 70, so that the display assembly 200 can be temporarily supported integrally, and the display assembly 200 can be conveniently connected with the fixed structure of the rear shell 20 to be aligned. In addition, more importantly, the sliding structure (91a, 91b, 91c) on the back support 90 protrudes out of the back edge of the rear screen assembly 70, so that in the process of installing the display assembly 200 into the rear housing 20, except for the sliding fit between the sliding structure (91a, 91b, 91c) on the back support 90 and the sliding butt-joint structure (22a, 22b, 22c), other parts of the display assembly 200 are not easy to touch the non-target structure of the rear housing 20, thereby avoiding the displacement of the positions among the upper screen assembly 50, the half mirror 61 and the rear screen assembly 70, further ensuring the assembly quality of the product, and preventing the 3D display effect of the display assembly 200 from being reduced due to the collision of assembly links.
Further, referring to fig. 14 to 17, in an embodiment, the plurality of sliding docking structures (22a, 22b, 22c) include an upper sliding docking structure 22a, a lower sliding docking structure 22b and a plurality of side sliding docking structures 22c, the upper sliding docking structure 22a and the lower sliding docking structure 22b are respectively located at the upper portion and the lower portion of the rear housing 20, and the plurality of side sliding docking structures 22c are respectively located at the left side and the right side of the rear housing 20;
the back support 90 comprises a vertical plate 92 and two side plates 93, wherein the vertical plate 92 extends along the vertical direction, and the two side plates 93 extend from the left side and the right side of the vertical plate 92 along the direction departing from the vertical plate 92;
the plurality of sliding structures (91a, 91b, 91c) include an upper sliding structure 91a, a lower sliding structure 91b, and two side sliding structures 91c, the upper sliding structure 91a and the lower sliding structure 91b are respectively disposed at the upper and lower ends of the vertical plate 92, and the two side sliding structures 91c are respectively disposed at the ends of the two side plates 93 away from the vertical plate 92.
In this embodiment, the plurality of sliding interfaces (22a, 22b, 22c) are distributed on the upper portion, the lower portion, and the left and right sides, so that the rear case 20 can form a stable supporting structure for the rear bracket 90 and thus the display module 200 after being engaged with the sliding structures (91a, 91b, 91c) of the rear bracket 90. The rear bracket 90 is shaped to radiate outward from the center, such that the sliding structure (91a, 91b, 91c) and the sliding abutting structure (22a, 22b, 22c) form a more stable supporting structure, and at the same time, the rear panel assembly 70 forms more exposed portions on the rear surface, thereby facilitating the connection of other components to the rear surface of the rear panel assembly 70, for example, via the second fixing structure 712 of the following embodiment, and facilitating the formation of air holes, wire passing holes, etc. on the rear surface of the rear panel assembly 70.
Further, referring to fig. 18 to 20, in an embodiment, the mirror assembly 60 further includes a mirror support 62, the mirror support 62 is in a ring shape penetrating from front to back, the half mirror 61 is mounted at the front end of the mirror support 62, and the rear end of the mirror support 62 is fixedly connected to the rear panel assembly 70;
the width of the vertical plate 92 is larger than that of the side plate 93, the back support 90 further comprises a bottom plate 94 extending forward from the lower end of the vertical plate 92, the bottom plate 94 is positioned at the lower side of the rear screen assembly 70, and the lower sliding structure 91b is arranged on the bottom plate 94; the base plate 94 is fixedly connected to the mirror support 62.
Compared with the half mirror 61 and the display screen of the rear screen assembly 70 or the upper screen assembly 50 sharing the same support frame, the half mirror 61 is mounted on the mirror support 62 in the embodiment, so that the modular assembly is facilitated, the corresponding support frame is simplified, and the molding difficulty and the manufacturing cost of the support frame are reduced. Because the bottom plate 94 of the back support 90 is fixedly connected with the reflector support 62, and the bottom plate 94 is connected at the lower end of the vertical plate 92, the vertical plate 92 is closer to a fixed point than the side plate 93, and the width of the vertical plate 92 is designed to be larger than that of the side plate 93, so that the self strength of the vertical plate 92 is ensured, and meanwhile, the sufficient support can be provided for the side plate 93.
Further, referring to fig. 5 to 13, in an embodiment, each of the plurality of sliding abutting structures (22a, 22b, 22c) is a groove opened toward the center of the front mounting opening 21, and the sliding abutting surface of the upper sliding abutting structure 22a protrudes forward from the sliding engaging surface of the upper sliding structure 91 a; the slide mating face of the side slide mating structure 22c projects forwardly of the slide mating face of the side slide structure 91 c; the upper slide interface structure 22a has a greater slot width than the side slide interface structure 22c, and the side slide interface structure 22c has a greater slot width than the lower slide interface structure 22 b.
In this embodiment, the plurality of sliding interfaces (22a, 22b, 22c) are distributed on the upper portion, the lower portion, and the left and right sides, so that the rear case 20 can form a stable supporting structure for the rear bracket 90 and thus the display module 200 after being engaged with the sliding structures (91a, 91b, 91c) of the rear bracket 90. Since the sliding interfaces (22a, 22b, 22c) are arranged in the inner cavity of the rear shell 20, the sliding interfaces (22a, 22b, 22c) are arranged in a groove shape, so that the mistaken collision is reduced in the assembling process. Since only the lower end of the back bracket 90 is fixed, the upper sliding structure 91a and the side sliding structure 91c, which are relatively close to each other, have the possibility of swinging in the front-back direction or even in the left-right direction, and by increasing the length of the sliding interface of the upper sliding interface structure 22a and the side sliding interface structure 22c in the front-back direction, the upper sliding structure 91a and the side sliding structure 91c can be correspondingly guided and matched in advance, so that the swinging of the back bracket 90 is reduced, and the auxiliary lower sliding structure 91b is aligned with the lower sliding interface structure 22b, so that the assembly of the display module 200 is smoother. Since the upper and side sliding structures 91a and 91c are relatively far from the fixing point of the rear bracket 90 and the mirror bracket 62, there is a greater possibility of shaking, so that the assembly is easier to observe by increasing the size of the relevant structure. Preferably, in order to better slide the sliding structures (91a, 91b, 91c) into the corresponding sliding docking structures (22a, 22b, 22c) by position correction, the front end entrances of the upper sliding docking structure 22a, the lower sliding docking structure 22b and the plurality of side sliding docking structures 22c are formed with guide slopes (not labeled).
Furthermore, two end portions of the lower edge of the front mounting opening 21 extend backwards to form a cantilever beam 23a, the rear shell 20 further includes a cross beam 23b connecting the rear ends of the two cantilever beams 23a, two lower sliding butt joint structures 22b are provided, and the two lower sliding butt joint structures 22b are located at two ends of the cross beam 23b respectively; two side edges of the front mounting opening 21 are respectively extended backwards to form a guide beam 24, and the side sliding butt joint structure 22c is positioned at the rear end of the guide beam 24.
In this embodiment, the cantilever and the cross beam 23b are arranged to enable the two lower sliding butt joint structures 22b to move backward relative to the edge of the front mounting opening 21, so as to avoid concentrating on the edge of the front mounting opening 21 to support the back support 90, and meanwhile, keep a relatively hollow structure, thereby improving the mobility of available internal space or internal air; compare the inner wall that sets up a whole circle, then set up side sliding butt structure 22c on this inner wall, through setting up a unsettled guide beam 24, not only can lengthen leading spigot surface, but also can keep the relative hollow out structure of backshell 20 inner chamber. Preferably, the guide beam 24 is plate-shaped, and the plate surface of the guide beam 24 faces the center of the front mounting opening 21, and in order to increase the strength of the guide beam 24 and prevent the guide beam 24 from being bent excessively, the back surface of the guide beam 24 facing away from the front mounting opening 21 is provided with a reinforcing rib.
Furthermore, the upper edge of the front mounting opening 21 extends downwards to form a connecting plate 25, and the light shield 10 is fixedly connected with the connecting plate 25; the upper sliding abutting structure 22a includes an upper abutting plate 26 and two side abutting plates 27, the upper abutting plate 26 is formed by extending backward from the lower edge of the connecting plate 25, and the two side abutting plates 27 are formed by extending downward from the left and right edges of the upper abutting plate 26, respectively.
In this embodiment, since the connection plate 25 is formed to be relatively convex downward after the connection plate 25 is provided, the connection plate 25 becomes a portion which is likely to collide with the display module 200, and the upper docking plate 26 is smoothly provided on the lower edge of the connection plate 25, and the two side docking plates 27 are respectively connected to both sides of the upper docking edge, so that the portion which is most likely to collide forms the upper sliding docking structure 22a, thereby protecting the display module 200.
