Compared with the projection area 301 formed at the top end of the front panel assembly 300, the projection area 301 formed on the front panel 303 is convenient for people to view, and the area of the front panel 303 is larger, so that the projection image 202 can be enlarged as required.
In order to facilitate the viewing of the projected image 202, the front plate 303 is a transparent structure 330 at least at the location of the projection area 301.
The reflective structure 351 can be any structure that can reflect light, such as a reflective film disposed on the rear end plate 304 for reflecting light, and a reflective plate disposed separately for reflecting light.
In some embodiments, the rear end plate 304 has a multifold surface formed by several slopes 352 connected end to end in sequence, the multifold surface forming a reflective structure 351. In one embodiment, the rear end plate 304 is integrally disposed at an angle, and the multifold surface forms an obtuse angle with the bottom plate 308 of the drawer body 200.

In some embodiments, a light guide 354 is disposed within the reflective cavity 350; the projected light 204 is projected through the light transmissive structure 321 toward the reflective cavity 350, and reflected by the light guide 354 toward the reflective structure 351. The light guide member 354 may be a glass lens or an acrylic, and has a good light guide performance, so that the projection effect of the projection light 204 can be improved, and the projection image 202 is clearer. Specifically, a hollow frame may be fixedly disposed below the top plate 302, and the light guide 354 is disposed in the hollow frame. It is understood that the light guide 354 may be positioned anywhere after the projected light rays 204 enter the front panel assembly 300 and before reaching the reflective structure 351.
In some embodiments, the drawer 130 further includes a pattern decal assembly 500 disposed between the beam emitter 203 and the projection area 301. The graphic pad pasting assembly 500 has a graphic of the control interface of the drawer 130 thereon. Which allows projected light rays 204 to pass through to form a control interface for drawer 130 at projection area 301. Assuming four adjustment functions for the drawer 130, four different images A, B, C, D are displayed on the control interface forming the drawer 130.
In one embodiment, the light-emitting side of the opaque plate 403 is provided with a second pattern film 502. Altering the size of the projected pattern is accomplished by adjusting the distance between the second pattern decal 502 and the beam emitter 203.
In one embodiment, the top plate 302 has a first graphic overlay film 501 disposed thereon. The provision of the first graphic film 501 may assist in enhancing the sharpness of the image of the projected light rays 204.
In one embodiment, the first pattern film 501 and the second pattern film 502 are opaque films with pattern holes 521.
