Electronic device

Technical Field

The present invention relates to the field of electronic devices, and in particular, to an electronic device.

Background

Along with the improvement of user demands, the types of electronic equipment on the market are more and more, and the electronic equipment is greatly convenient for users to use. Taking the air detector as an example, the air detector may detect some detection parameters during the operation process, and the housing of the air detector generally includes a light-transmitting portion, and the air detector can control the light-emitting body in the housing to emit light according to the detection result. The light transmission part can transmit light rays emitted by the luminous body, the purpose of light emitting prompt of the electronic equipment is achieved, the color of the light rays emitted by the luminous body can be different according to different detection results, and the light transmission part can transmit light rays with different colors. For example, when the detected humidity of the air exceeds a preset humidity value, the light-transmitting part can transmit light with a set color.

The light emitting body of the electronic device is usually disposed in the housing of the electronic device, and the light emitted by the light emitting body directly passes through the light-transmitting portion and then is projected out of the electronic device. In order to achieve more uniform light emission, the conventional design method is to increase the distance between the light emitter and the light transmission part. However, the overall size of the electronic device is generally small, and it is difficult to have a large installation space to increase the distance between the light emitter and the light transmission portion. Obviously, the current electronic equipment has small size and small distance between the light emitter and the light transmission part, so that the light passing through the light transmission part has the problem of non-uniformity.

In addition, in the existing electronic device, the light-emitting surface of the light-transmitting portion is usually a curved surface region, so that the light-emitting body needs to be arranged on the bent flexible circuit board, the surface of the flexible circuit board on which the light-emitting body is arranged is a non-planar surface, and the mounting surface of the light-emitting body is usually a planar surface, so that the light-emitting body cannot form a stable assembly relationship with the non-planar flexible circuit board.
