The outer circumference of the light guide plate 30 protrudes from the light shielding plate 10, so that the side of the light shielding plate 10 facing away from the light guide plate 30 can display an annular aperture, thereby increasing the light interaction with the user. Therefore, through the cooperation of the light guide plate 30 and the light shielding plate 10, the brightness of the light-emitting patterns can be more uniform, the patterns, brightness and colors of the light-emitting patterns can be controlled, the visual effect of the cover plate assembly 100 is improved, the interaction of a user is increased, the playability of the cover plate assembly 100 is improved, and the user experience is improved.

The light emitting portion 31 protrudes from the light shielding plate 10, so that when the light emitting module 50 emits light, an aperture of a light emitting pattern is displayed on the light shielding plate 10 side of the cover module 100. The light emitting part 31 and the bearing part 33 are bent and connected, and enclose to form a first accommodating cavity 301, and the first accommodating cavity 301 is used for accommodating the light shielding plate 10; the connecting part 35 is arranged at one end of the bearing part 33 departing from the light emergent part 31, is connected with the bearing part 33 in a bending way, and bends towards the direction departing from the light emergent part 31; the light incident portion 37 is disposed at one end of the connecting portion 35 away from the carrying portion 33, is connected to the connecting portion 35 in a bending manner, and is bent towards a direction away from the carrying portion 33, so as to be used for incident light. After the light emitted from the light emitting assembly 50 enters the light guide plate 30, the longer the path of the light transmitted in the light guide plate 30, in other words, the longer the distance between the light incident portion 37 and the light emitting pattern display area, the more uniform the brightness and color of the displayed light emitting pattern, and the better the visual effect of the light emitting pattern. The light emitting part 31, the bearing part 33, the connecting part 35 and the light entering part 37 are sequentially bent and connected, so that the length of a transmission path of light in the light guide plate 30 can be increased in a limited plane area, the brightness and the color of the light emitted out of the light guide plate 30 are more uniform, and the displayed luminous pattern has a better visual effect.

It should be understood that the plurality of light emitting units 53 are disposed corresponding to the position of the light incident portion 37 of the light guide plate 30 (in other words, the light emitting units 53 are disposed below the light incident portion 37), and light emitting surfaces (not shown) of the plurality of light emitting units 53 face the light incident portion 37 for emitting light toward the light incident portion 37, and the light enters the light guide plate 30 and then sequentially passes through the connecting portion 35, the supporting portion 33 and the light emitting portion 31. When the light shielding plate 10 does not have the hollow portion 11, the light finally exits through the light emitting portion 31, and when the light shielding plate 10 has the hollow portion 11, the light finally exits through the light emitting portion 31 and the hollow portion 11.

Alternatively, the plurality of light emitting cells 53 are arranged at intervals in a ring-shaped arrangement. The number of the light emitting units 53 is at least two, and specifically, may be, but is not limited to, 2, 4, 6, 8, 10, 12, 14, 18, 24, and the like.

The line width of the second limiting member 65 is too large, so that a new processing error (the processing error of the second limiting member 65) is easily formed, and the accurate alignment between the pins 711 of the cover plate assembly 100 and the contacts of the external electronic device is not facilitated. Therefore, the line width of the second limiting member 65 should be smaller than the processing tolerance of the first limiting member 63.
