The flange structures 32 of the plurality of clamping units 30 form a clamping space with the top surface of the first long side 111, the clamping space is used for clamping the decorative plate 20, and the plurality of screw hole fixing columns 12 are used for matching with the assembly holes 21 and the screws to fix the decorative plate 20. When the decorative plate 20 is assembled, only one side of the decorative plate 20 needs to be pressed into the flange structures 32 of the plurality of clamping units 30 along the inclined edge of the light outlet 11 to realize clamping, and then the assembling hole 21 on the other side of the decorative plate 20 is fixed on the screw hole fixing column 12 through a screw, so that the decorative plate 20 can be stably fixed to the light outlet 11. The decorative plate 20 is fixed to be low in front and high in back, and the height difference of the front/back inclined planes is suitable for the ultra-short-focus projector, because the light path of the ultra-short-focus projector is obliquely projected to the wall surface from the light outlet 11 of the top cover base body 10, the inclined structure can not shield the light path too much, and the appearance is also aesthetic.

In some embodiments, the side edge of the light outlet 11 forms an inclined ramp in the direction away from the light outlet 11, the height of the inclined ramp in the direction close to the light outlet 11 increases gradually, and the clamping unit 30 is disposed on the inclined ramp. In particular, the bottom of the support structure of the clamping unit 30 is located between the base and the top of the inclined ramp. As shown in fig. 4, the inclined ramps include a first inclined ramp 113 and a second inclined ramp 114, wherein the first inclined ramp 113 is formed on the first long side 111 in a direction away from the light outlet 11, and the second inclined ramp 114 is formed on the second long side 112 in a direction away from the light outlet 11. As can be seen from fig. 4, at the first long side 111 where one row of the clamping units 30 is disposed, the width of the first inclined ramp 113 is narrower, and at the second long side 112 where one row of the screw hole fixing columns 12 is disposed, the width of the second inclined ramp 114 is wider, because the mounting space occupied by the supporting structure 31 of the clamping unit 30 is smaller, and the screw hole fixing column 12 needs to be configured, a wider ramp structure (the second inclined ramp 114) needs to be necessarily provided, so that by disposing a plurality of clamping units 30, the occupied space of the assembly structure is also compressed to some extent, the influence on the arrangement position of the circuit board (including the microphone board 40, the main control board 50, and the like) is reduced, and the size of the top cover substrate 10 in a specific direction is further compressed.

In some embodiments, a supporting unit 60 is further disposed on the inner sidewall of the top cover base 10 and at the edge of the light outlet 11, the supporting unit 60 and the clamping unit 30 are disposed side by side on the same side of the light outlet 11, the top end of the supporting unit 60 is lower than the bottom of the flange structure 32 and higher than the top surface of the side edge at the edge of the light outlet 11 (in this embodiment, the top surface is higher than the first long side 111), and the side of the decorative plate 20 away from the flange structure 32 abuts against the supporting unit 60. Wherein, the top of support element 60 can be higher than the side top surface at the edge of light-emitting window 11 by 0.1mm ~ 0.2mm, and support element 60's top is higher than the top surface of first long side 111 by 0.1mm ~ 0.2mm promptly, supports the top surface and the bottom surface that carry on the back of decorative board 20 edge respectively through the flange structure 32 of joint unit 30 and the top surface of support element 60, realizes spacing from top to bottom. At this time, the decoration plate 20 is directly pressed on the supporting unit 60 after being assembled and fixed, not on the top side of the edge of the light outlet 11 (the top side of the first side 111 in this embodiment), thereby further improving the assembling stability of the decoration plate 20.

The inventor found through research that, in the case where the first inclined ramp 113 is provided around the light exit 11, when the fastening force of the decorative plate 20 mounted from inside to the inner side wall of the top cover base 10 is too large, and the decorative plate 20 directly abuts against the top edge of the first inclined ramp 113 (i.e., the top surface of the first long side 111), the fastening force may be transmitted to the inclined structure of the first inclined ramp 113, and the top edge may be deformed perpendicular to the inclined direction, which may cause misalignment between the light exit 11 and the decorative plate 20, and a large gap may occur between the decorative plate 20 and the top cover base 10 when viewed from the external appearance. Based on this, in a further embodiment, by providing a plurality of supporting units 60, the supporting units 60 are slightly higher than the top edge of the first inclined ramp 113, and the supporting units 60 extend to the bottom of the ramp structure (the first inclined ramp 113), so that the supporting units 60 can replace the top edge of the first inclined ramp 113 (i.e. the top surface of the first long side 111) to abut against the decorative plate 20, and further the fastening force from the decorative plate 20 is transmitted from the supporting units 60 to the bottom of the ramp structure (the first inclined ramp 113), which will not cause the deformation of the light outlet 11 and the misalignment between the light outlet 11 and the decorative plate 20.

In some embodiments, the edge of the decorative plate 20 is provided with a concave fastening position 22, and the concave fastening position 22 is fastened to the fastening unit 30. Specifically, the female snap locations 22 correspond to the positions and the number of the clamping units 30 so that each female snap location 22 can be correspondingly snapped at each clamping unit 30. Position 22 is detained to the indent through offering corresponding to joint unit 30 at the edge of decorative board 20, make joint unit 30 can set up in the position that is closer to light-emitting port 11, and no longer need move outward toward the direction of keeping away from light-emitting port 11 just can cooperate the edge of blocking decorative board 20, thereby can avoid interfering the position of microphone board 40, consequently, detain position 22 through the indent that sets up cooperation joint unit 30, can further realize the ascending spacing of decorative board 20 length direction on the one hand, on the other hand also can avoid decorative board 20 to surpass the position of joint unit 30 along the installation direction, in order to further reduce the interference to the circuit board (including microphone board 40, parts such as main control board 50).
