Being applied to portable health detection equipment such as intelligent wrist-watch, intelligent bracelet at present, in order to make it have better appearance effect, can set up the outward appearance layer on the casing usually to avoid the homogenization, improve the pleasing to the eye of casing. However, in order to avoid the loss of light during transmission as much as possible at the positions on the housing corresponding to the light emitter and the light receiver, the positions on the housing corresponding to the light emitter and the light receiver are generally designed to be transparent or translucent, and the other positions are not translucent. After the whole appearance layer is formed, etching such as laser etching is performed on the positions corresponding to the light emitter and the light receiver, and the film layer (such as ink) with the decoration function is usually made of opaque or semi-opaque materials.

Referring to fig. 1 and 2, an embodiment of the present application provides a housing assembly 100, which includes: the light source module comprises a shell 10, wherein the shell 10 comprises a first light transmission area 11, a second light transmission area 13 and a first light blocking part 15, the first light transmission area 11 and the second light transmission area 13 are arranged at intervals through the first light blocking part 15, and the first light blocking part 15 is respectively connected with the first light transmission area 11 and the second light transmission area 13; the decoration layer 30, the decoration layer 30 is arranged on the surface of the shell 10; and a second light blocking portion 50, wherein the second light blocking portion 50 is disposed on the decoration layer 30, and is configured to prevent light rays emitted from the first light transmitting area 11 and light rays incident on the second light transmitting area 13 from passing through the decoration layer 30 and escaping. Optionally, the decoration layer 30 is disposed corresponding to a gap between the first light-transmitting area 11 and the second light-transmitting area 13; in other words, the orthographic projection of the decoration layer 30 on the housing 10 falls within the orthographic projection of the housing 10 in the gap between the first light-transmitting area 11 and the second light-transmitting area 13.

The term "corresponding" in the present application means that the orthographic projection of the portion on the housing 10 at least partially overlaps with the orthographic projection of another portion on the housing 10, or that the orthographic projection of the portion on the housing 10 falls within the orthographic projection area of another portion on the housing 10; or the orthographic projection of the part on the housing 10 overlaps with the orthographic projection of another part on the housing 10.

In one embodiment, the light emitted from the first light-transmitting region 11 is reflected and then enters the second light-transmitting region 13.

The casing assembly 100 of the embodiment of the present application is provided with the decoration layer 30 on the surface of the casing 10, so that the casing assembly 100 has a better appearance effect, and homogeneity is avoided. Meanwhile, the second light blocking part 50 is arranged on the decoration layer 30, so that light rays emitting out of the first light transmission area 11 and light rays emitting into the second light transmission area 13 can better penetrate through the decoration layer 30 to be emitted, when the decoration layer is applied to electronic equipment such as health detection equipment, measurement errors caused by emitted light can be better prevented, and the measurement accuracy of the electronic equipment is improved.

Alternatively, the housing 10 may be formed by two-color injection molding using a colored resin that forms the first light blocking portion 15 and a transparent resin that forms the first light transmission region 11 and the second light transmission region 13. The colored resin may be, but is not limited to, an opaque resin such as a black resin, a gray resin, etc.

Alternatively, the number of the first light transmission regions 11 may be 1 or more. The shape of the first light-transmitting region 11 may be, but is not limited to, circular, square, regular triangle, regular hexagon, star, oval, etc.

Alternatively, the number of the second light transmission regions 13 may be one or more. When the number of the second light transmission regions 13 is one, the second light transmission regions 13 are spaced apart from the first light transmission regions 11. When the number of the second light transmission regions 13 is plural, the plural second light transmission regions 13 are disposed at intervals and surround the first light transmission region 11. As shown in fig. 1, in some embodiments, the plurality of second light-transmitting regions 13 are uniformly or symmetrically disposed around the first light-transmitting region 11. In other embodiments, the plurality of second light-transmitting areas 13 are not uniformly disposed around the first light-transmitting area 11.

Alternatively, the shape of the second light-transmitting region 13 may be, but is not limited to, a circle, a square, a regular triangle, a regular hexagon, a star, an ellipse, and the like.

If the appearance layer 33 partially remains on the first light-transmitting area 11 and the second light-transmitting area 13 of the housing 10, the loss of light propagating in the housing assembly 100 may increase, thereby reducing the accuracy and precision of the detection of the electronic device.

the housing assembly 100 according to the embodiment of the present application;

a light emitter 310, disposed on a side of the casing 10 away from the decoration layer 30, corresponding to the first light-transmitting area 11, and configured to emit light to the first light-transmitting area 11; and

and the light receiver 330 is arranged on the same side of the light emitter and corresponding to the second light-transmitting area 13, and is used for receiving the light emitted by the second light-transmitting area 13.

The light emitted from the light emitter 310 passes through the first light-transmitting region 11, reaches the skin surface, is emitted back, passes through the second light-transmitting region 13, and is transmitted to the light receiver 330 for sensing. Specifically, when a light beam of a certain wavelength emitted from the light emitter 310 is irradiated to the skin surface, the light beam is transmitted to the light receiver 330 by transmission or reflection, and the intensity of the light monitored by the light receiver 330 is reduced due to attenuation caused by absorption by skin muscles and blood. The reflection of skin, bone, meat, fat, etc. of human body to light is fixed value, and the capillary vessel and artery and vein continuously increase and decrease with the pulse volume under the action of heart. When the heart contracts, the peripheral blood volume is the largest, the light absorption amount is also the largest, and the light intensity detected by the light receiver 330 is the smallest; on the contrary, when the heart is in diastole, the light intensity detected by the light receiver 330 is the maximum, so that the light intensity received by the light receiver 330 is pulsatory.

Alternatively, the Light emitter 310 may be, but is not limited to, a Light-Emitting Diode lamp (LED lamp), a Micro LED lamp, etc. (Micro LED lamp), a sub-millimeter LED lamp (mini LED lamp or mini LED lamp), etc. The light emitter 310 may include one or more of a red light emitting unit, a blue light emitting unit, a green light emitting unit, an infrared light emitting unit, and a white light emitting unit. In other words, the light emitter 310 may emit one or more of red light, blue light, green light, infrared light, or white light.

Alternatively, the light receiver 330 may be, but is not limited to, a photodiode receiving sensor (PD receiving sensor). The number of the light receivers 330 may be one or more. When the number of the light receivers 330 is one, the light receivers 330 are spaced apart from the light emitter 310. When the number of the light receivers 330 is plural, the plural light receivers 330 are disposed at intervals and around the light emitter 310. In some embodiments, the plurality of light receivers 330 are uniformly or symmetrically disposed around the light emitter 310. In other embodiments, the plurality of light receivers 330 are disposed non-uniformly around the light emitter 310. When the number of the light receivers 330 is multiple, after the light emitted from the light emitter 310 is reflected to the light receivers 330, more light can be received by the light receivers 330, so that the detection error of the electronic device can be reduced, and the accuracy and precision of the detection of the electronic device can be improved.
