Referring to fig. 3 in conjunction with fig. 1 and 2, in the related art, a bottom case assembly for a portable electronic device includes an appearance lens 101, a light sealing bracket 2, a circuit board 5, an optical sensor, a housing 102, a support 6, and a wireless charging coil 103, wherein the optical sensor includes at least one light emitting device 3 and at least one light receiving device 4, and the optical sensor is disposed on the circuit board 5. Referring to fig. 2 in conjunction with fig. 1 and 3, the appearance lens 101 is disposed in the opening of the housing 102, the appearance lens 101 includes an emission transparent area 111 and a receiving transparent area 112, the emission transparent area 111 is disposed corresponding to the light emitting device 3, so that light emitted from the light emitting device 3 can pass through the emission transparent area 111 and emit to a human body. Accordingly, the light receiving transmission region 112 is disposed corresponding to the light receiving device 4, so that the light receiving device 4 can receive light reflected or refracted by the human body through the light receiving transmission region 112. The appearance lens 101, the light sealing support 2, the light emitting device 3, the light receiving device 4 and the circuit board 5 are matched to detect physiological parameters such as heart rate, blood oxygen and blood pressure through optical signals. The light sealing support 2 is used for isolating the light emitted by the light emitting device 3 from the light received by the light receiving device 4 so as to avoid light crosstalk. Referring to fig. 3 in conjunction with fig. 1, the supporting member 6 has one side connected to the inner surface of the housing 102 and the other side connected to the circuit board 5.
Specifically, with reference to fig. 1 and fig. 2 and fig. 3, in the bottom housing assembly, the appearance lens 101 is adhered to the supporting member 6 by dispensing or adhesive tape. In order to achieve a good waterproof function, the width of the waterproof structure 104 (the area where the waterproof structure 104 is located is indicated by a circle of shaded areas in fig. 1 and 2) around the periphery of the design lens 101 is at least 0.8mm. After analysis by a technician, the area where the waterproof structure 104 is located cannot be used as a light transmission area, so that the effective area of the appearance lens 101 is reduced, and the effective area of the appearance lens 10 is smaller; furthermore, the small area of the appearance lens 101 makes the areas of the emission light-transmitting area 111 corresponding to the light-emitting device 3 and the reception light-transmitting area 112 corresponding to the light-receiving device 4 relatively small, which both affect the accuracy and power consumption of physiological parameter detection and, in addition, affect the layout of the light-receiving device 4 and the light-emitting device 3.
Referring to fig. 3 in conjunction with fig. 1, on the other hand, the housing 102 includes a housing through hole 1021 penetrating through the housing 102.

As shown in fig. 3, in the bottom shell assembly, a is the wall thickness of the supporting member 6, B is the thickness of the light sealing bracket 2, and C is the thickness of the foam disposed between the light sealing bracket and the appearance lens. The circuit board 5 is fixed on one side surface of the support piece 6 through processes such as structural hot stamping and the like, and the foam compresses the appearance lens 101 to realize light sealing. The compression amount of the foam = B + C-A, and reliable light sealing can be realized only when the compression amount is proper. If the compression amount is too small, light leaks, if the compression amount is too large, the pressure is too large, and the design lens 101 may be pushed out. In actual production, the sealing effect is influenced by the problems of processing deformation of a structural part and assembly deformation of the whole machine. Therefore, the bottom shell assembly has high process requirements due to the existence of packaging matching of a plurality of devices, and the light sealing effect and the equipment reliability are difficult to ensure due to the packaging tolerance accumulation effect.

As set forth above, because circuit board 5 with support piece 6 assembles for whole and the internal surface of printing opacity shell 1 and support piece 6's surface laminating, like this, the three constitutes wholly, damage when avoiding falling printing opacity shell 1. Here, although the reliability of the sealing is inferior to the reliability of the embodiment in which the circuit board 5 and the sealing holder 2 are both attached to the holder 6, the reliability is superior to the embodiment in which the design lens 101 and the circuit board 5 are attached to the holder 6 and the sealing holder 2 is attached to the circuit board 5.
