Background

Physiological parameter monitoring has become the standard matching function of wearable devices (such as smart band, smart watch). Physiological parameter monitoring is mainly used for monitoring or detecting physiological parameters such as heart rate, pulse, etc. of a user. Wearable devices are commonly monitored for physiological parameters by photoelectric measurement methods. The reflection of light is kept constant due to the skin, bones, meat, fat, etc. of the human body. The volume of blood in the skin changes in pulsation under the action of the heart. When the heart contracts, the peripheral blood volume is at its maximum and the light absorption is at its maximum, the reflection of light is smaller, whereas at the diastole, the opposite is the reflection of light larger. Therefore, the reflection of light by the human body fluctuates, and the frequency of the fluctuation is the pulse, which is consistent with the heart rate of the human body. Thus, the physiological information of the human body is indirectly detected by monitoring the reflection condition of the visible light (such as green light and red light) in the human body tissue.

The existing smart bracelet generally includes a main unit and a watchband that attaches the main unit to a wrist. The host typically includes a housing, a light source, a light detector, and a processing chip. The light source, the light detector and the processing chip are mounted on the housing.

The light emitted by the light source is emitted to the wrist through the light-transmitting portion. The light detector receives the light reflected back through the wrist and converts the light into corresponding electric signals. The processing chip calculates corresponding physiological parameter values according to the electric signals. However, in the existing smart bracelet, the casing is generally made by two-shot molding, however, the adoption of two-shot molding often results in thicker thicknesses of the lower casing and the light transmission part.

To maintain the following description of the embodiments of the present disclosure clear and concise, a detailed description of known functions and known components have been omitted from the present disclosure.

Referring to fig. 1, wearable device 99 may be configured in the form of, but not limited to, a bracelet, a watch, a ring, an arm band, and the like. In this embodiment, the wearable device 99 is provided as a strap bracelet. The wearable device 99 includes a physiological parameter monitoring apparatus 100 and a watchband 200. The wristband 202 is used to attach the physiological parameter monitoring device 100 to, but not limited to, a wearer's wrist, arm.

Referring to fig. 2, the physiological parameter monitoring device 100 includes a housing 20, a physiological parameter monitoring module 10, and a light shielding member 30. Wherein, physiological parameter monitoring module 10 fixed mounting is in casing 20, and light-shielding piece 30 is located between physiological parameter module 10 and the casing 20 and is extruded and takes place the deformation.

Referring to fig. 3-4, the physiological parameter monitoring module 10 includes a carrier 11, a light source 12, and a photodetector 13. The light source 12 and the photodetector 13 are mounted on the carrier plate 11. In the present embodiment, the number of the photodetectors 13 is 2. The carrier 11 is substantially rectangular, and the carrier 11 includes a first carrying surface 111 and a second carrying surface 112 opposite to the first carrying surface 111. The light source 12 and the light detector 13 are disposed on the first supporting surface 111, and the two light detectors 13 are symmetrically disposed on two sides of the light source 12.

Specifically, the physiological parameter monitoring module 100 measures the heart rate of the user by using the Principle of Photoplethysmography (PPG). It will be appreciated that the type of light source 12 may be selected based on the measured physiological parameter. For example, if light source 12 is required for the purpose of measuring heart rate, the type of light source 12 is preferably an LED that emits green light, since green light may be more visible and less disturbing due to light reflected back from the skin of a person. If used to measure other physiological parameters than heart rate, such as blood oxygen level, the light source 12 is preferably of the type that emits red or infrared light. In the present embodiment, the physiological parameter monitoring module 100 mainly utilizes the light source 12 to measure the heart rate, so a green light emitting LED is preferred as the first light source 11.

Specifically, the two photodetectors 13 are phototransistors, such as Photodiodes (PDs). The centers of the sensing areas of the two photodetectors 13 and the center of the light emitted from the light source 12 are located on the same straight line. The light sensing area of the light detector 13 is a regular pattern, and a square shape is adopted in the present embodiment. In some possible embodiments, the light sensing area of the light detector 20 may also be rectangular or other patterns.

Referring to fig. 5 to 6, the housing 20 is integrally formed. The housing 20 includes a main body 21, a first light-transmitting member 23a, and a second light-transmitting member 23 b. The body 21 includes a bottom 210, and a window area 212 formed in the bottom 210. The first and second light-transmitting members 23a and 23b are disposed in the window area 212. The window area 212 is provided with a light blocking portion 2125 surrounding the first light transmitting member 23a and the second light transmitting member 23b, so that the window area 212 forms a light emitting window 214 and two sensing windows 216. In the present embodiment, the light emission windows 214 and the two sensing windows 216 correspond to the light sources 12 and the light detectors 13, respectively, one to one. Wherein, the housing 20 is formed by two-color injection molding. The light-transmitting member 23 is made of a light-transmitting material, such as PC. The body 21 is made of a non-light-transmitting material, such as ABS. When the physiological parameter monitoring module 100 is mounted in the housing 20, the bottom portion 210 covers one side of the carrier plate 11, which is provided with the light source 12 and the light detector 13, and the light source 12 and the light detector 13 correspond to the light-emitting windows 214 and the sensing windows 216 one by one.

Bottom 210 includes an inner bottom surface 2101 facing carrier plate 11 and a back surface 2103 opposite inner bottom surface 2101. The window area 212 includes an inner surface 2121 and an outer surface 2123 opposite the inner surface 2121. Inner surface 2121 is recessed relative to inner bottom surface 2101. The outer surface 2123 protrudes from the back surface 2103. The thickness of the bottom 210 is 0.6-0.8 mm.

The first light-transmitting member 23a and the second light-transmitting member 23b are substantially made of a sheet-like light-transmitting material. In the present embodiment, the light-transmitting material is preferably PC, and the first light-transmitting member 23a and the second light-transmitting member 23b have substantially the same structure. Specifically, the first light-transmitting member 23a includes a base 230a, an extension 232a extending from a periphery of an end face 2301a of the base 230a, a groove 236a surrounded by the base 230a and the extension 232a, a groove wall 238a surrounding the groove 236a, and an injection molding 234a extending from the extension 232 a. The base 230a has a substantially trapezoidal longitudinal cross section, i.e., the base 230a gradually increases from an end away from the extension wall 232a to an end connected to the extension wall 232 a. Substrate 230 includes a light-transmissive surface 2302a opposite end surface 2301 a. The light-transmitting surface 2302a is formed on the outer surface 2123 of the window area 212 and is located on the same plane as the outer surface 2123. The first light-transmitting member 23a further includes an outer sidewall 234a, the outer sidewall 236a being formed by an outer sidewall of the base 230a and an outer sidewall of the extension 232 a.

The second light-transmitting member 23b also includes a base 230b, an extension 232b extending from the periphery of the end face 2301b of the base 230b, a groove 236b surrounded by the base 230b and the extension 232b, and a molding (not shown) extending from the extension wall 232 b. The first and second light-transmitting members 23a and 23b are different in that: the first and second light-transmitting members 23a and 23b are provided in one-to-one correspondence with the light sources 12 and the photodetectors 13, with a certain difference in size. The thickness of the first light-transmitting member 23a and the second light-transmitting member 23b is 0.7-0.8 mm.

In the present embodiment, the outer sidewall 236a and the injection molding portion 234a of the first light-transmitting member 23a, and the outer sidewall 236b and the injection molding portion (not shown) of the second light-transmitting member 23b are all covered by the main body 21 made of a non-light-transmitting material, so that the

substrates

230a and 230b form corresponding windows, i.e., the light-emitting window 214 and the sensing window 216, and the light-blocking portion 2125, on the window area 212. There is a gap G between the

substrates

230a, 230b and the light detector 103 and light source 102. It will be appreciated that the light-

transmissive surfaces

2302a, 2302b and the

groove walls

238a, 238b of at least the first and second light-transmissive members 23a, 23b are ensured not to be covered by a non-light-transmissive material.

The light blocking part 2125 surrounds the first and second light transmitting members 23a and 23 b. The light blocking portion 2125 protrudes from the inner surface 2121 to form a first frame 2127 and a second frame 2129 as viewed from the inner surface 2121. The first frame 2123 and the second frame 2129 surround the light emission window 214 and the sensing window 216, respectively. The outer surface 2123 of the viewing window area 212 is planar when viewed from the outer surface 2123.

During injection molding, the first light-transmitting part 23a and the second light-transmitting part 23b are first injection molded by using a light-transmitting material, and then the main body 21 is injection molded by using a non-light-transmitting material. Because the first light-transmitting member 23a and the second light-transmitting member 23b are provided with the

grooves

236a and 236b, the first light-transmitting member 23a and the second light-transmitting member 23b cannot be automatically demolded after the injection molding is finished in the double-color injection molding process, so that the double-color injection molding with the main body 21 is completed. It can be understood that the

substrate

230a, 230b of the first and second light-transmitting members 23a, 23b can be injection molded with the main body 21 in two colors even at a relatively thin thickness, such as 0.7-0.8 mm. That is, since the first and second light-transmitting members 23a and 23b are structured, the first and second light-transmitting members 23a and 23b and the bottom portion 210, which are thin, can be formed by two-color injection molding.

Referring to fig. 2-4, the light shielding member 30 is substantially rectangular, and the size of the light shielding member is substantially matched with the size of the window area, in this embodiment, the light shielding member 30 is made of light-blocking foam material. In some possible embodiments, the light shielding member 30 may also be made of silicone. The light shielding member 30 is provided with a first opening 31 and a second opening 32, and the light sources 12 and the photodetectors 13 correspond to the first opening 31 and the second opening 32, respectively, one to one. The light shielding member 30 is disposed on the first carrying surface 111, and the light source 11 and the light detector 13 are exposed from the first opening 31 and the second opening 32. In the present embodiment, the light shielding member 20 is made of an adhesive material, such as glue, tape, etc., and is adhered to the first carrying surface 111 and surrounds the light detector 13 and the light source 12, so that the light emitted from the light source 12 is prevented from being emitted into the light detector 13. In some possible embodiments, the light shielding member 30 may be provided with only the second opening 32 and surround only the periphery of the light source 12, so that the light emitted from the light source 12 is prevented from entering the light detector 13. In some possible embodiments, the size of the shade 30 need not match the size of the bottom 210. The light shielding member 30 only surrounds the light source 12, that is, the light shielding member 30 may have a single frame shape covering the light source 12, and may prevent the incident light of the light source 12 from directly entering the light sensor 13. Alternatively, the light shielding member 30 may cover only the surroundings of the light source 12 and the photodetector 13, and may prevent the incident light from the light source 12 from directly entering the photodetector 13 and may prevent the ambient light from entering the photodetector 13.

Referring to fig. 2 again, when the physiological parameter monitoring module 10 is mounted in the housing 20, the light shielding member 30 is located between the carrier plate 10 and the bottom 21. The light shielding member 30 is deformed while abutting against the carrier plate 11 and the light blocking portion 2125, respectively. Therefore, the light shielding member 30 is filled between the light blocking part 2125 and the light blocking part 2125 corresponding to the first carrying surface 111, that is, the light source 12 and the light sensor 13 are under the action of the light blocking part 2125 and the light shielding member 30, the light emitted by the light source 102 is only emitted from the light emitting window 214, and the light sensor 13 can only receive the light absorbed from the sensing window 216, so as to prevent the light emitted by the light source 12 from directly entering the light sensor 13. And simultaneously prevents the ambient light from entering the light sensor 13, and prevents the ambient light from interfering. Therefore, the physiological parameter monitoring module 10 improves the detection accuracy.

Referring to fig. 10, in some possible embodiments, only one viewing window 214 'may be provided, and accordingly, the light-shielding member may be omitted or disposed around the viewing window 214', according to the actual needs. It will be appreciated that when only one window 214 'is provided, only one light transmissive member 23 is used to form the corresponding window 214'. The light-transmitting member 23 has a structure identical to that of the first and second light-transmitting members 23a and 23 b. Sized to cover both the light source (not shown) and the light detector (not shown). Due to the structure of the light-transmitting member 23, the thickness of the light-transmitting member 23 and the bottom 210 'of the housing can be thinner than that of the housing 20', and the two-shot molding can be adopted.

The above description is for the specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto, and any person skilled in the art can easily think of various equivalent modifications or replacements within the technical scope of the present invention, and these modifications or replacements should be covered within the protection scope of the present invention.
