Referring to fig. 1 to 4, fig. 1 is a schematic structural diagram of a wearable device 10 according to an embodiment of the present application, fig. 2 is a schematic structural diagram of an exploded electronic device 100 in fig. 1, fig. 3 is a schematic structural diagram of a connection between a housing component 120 and a light detection component 130 in fig. 2, and fig. 4 is a schematic structural diagram of an exploded housing component 120 in fig. 3.

The wearable device 10 provided by the embodiment of the application can be a smart watch or a smart bracelet, can be worn on the wrist of a user for use, can provide communication services such as voice communication and video chat for the user besides viewing services such as calendar and time for the user, and can monitor data indexes such as daily movement conditions and physical health conditions of the user. For example, the wearable device 10 may be provided with detection modules such as PPG (Photo Plethysmo Graphy), ECG (Electro Cardio Graphy) to implement a function of detecting the health status of the user. Of course, the functions of the wearable device 10 may be not limited to this, but the present embodiment is not limited to this, and only the wearable device 10 is exemplified as a smart watch.

As shown in fig. 1, the wearable device 10 may include: an electronic device 100 and a strap 200. The electronic device 100 is provided with straps 200 on opposite sides and the electronic device 100 may be provided with PPG (Photo Plethysmo Graphy) detection modules, which may be used to implement the health detection function of the wearable device 10. The straps 200 on the opposite sides may be connected and may form a wearing space together with the electronic device 100 after being connected, so that a user may wear the electronic device 100 on the wrist through the straps 200 for use. In particular, electronic device 100 may be a watch head in a smart watch, and strap 200 may be a wristband in a smart watch. The electronic device 100 may be provided with other electronic devices required by the smart watch, such as a battery, a camera, a speaker, a microphone, and the like, in addition to the PPG detection module. The strap 200 may be made of a flexible skin-friendly material, such as soft rubber, silica gel, hemp rope, and a composite material thereof, to improve wearing comfort of the user. Of course, the material of the strap 200 may be metal.

In some embodiments, the electronic device 100 may also be used not only in the wearable device 10, i.e. a smart watch, but also a stand-alone device, such as a professional medical device or a health detection device. Alternatively, the electronic device 100 may be a mobile phone, a tablet computer, a notebook computer, or the like with a health detection function, which is not limited in this embodiment.

The electronic device 100 may be used to implement the health detection functionality of the wearable device 10. As shown in fig. 2 to 3, the electronic device 100 may include: a display screen 110, a housing assembly 120, and a light detection assembly 130. The display 110 may be connected to the housing assembly 120, and both may together enclose a receiving space 101. The light detection assembly 130 may be disposed in the accommodating space 101, and the light detection assembly 130 may be configured to emit detection light and receive the detection light reflected back by the user's body. The display 110 may be used to implement an image display function of the electronic device 100, so that a user may perform man-machine interaction with the wearable device 10 through the display 110. The housing assembly 120 may be used to transmit the detection light emitted by the light detection assembly 130, so that the detection light may be transmitted out of the accommodating space 101 through the housing assembly 120, and may be transmitted into the accommodating space 101 through the housing assembly 120 after being reflected. The light detection component 130 may be the PPG detection module described above, which may analyze the detected light with the user's body tissue information, thereby implementing the health detection function of the wearable device 10.

The display screen 110 may be used to provide image display functionality for the wearable device 10, and a user may also interact with the wearable device 10 through the display screen 110. Specifically, the display screen 110 may include a transparent cover plate, a display panel, and a touch panel that are stacked, and the touch panel is disposed between the transparent cover plate and the display panel. The transparent cover plate may be used to protect the display panel, which may serve as an outer surface of the electronic device 100. The display panel may be used for image display. The touch panel may be used to implement human-machine interaction functions. The transparent cover plate, the display panel and the touch panel can be bonded together by means of colloid such as OCA (Optically Clear Adhesive, optical cement), PSA (Pressure Sensitive Adhesive ) and the like.

Specifically, the surface of the transparent cover plate may have a flat and smooth characteristic, so that a user can perform touch operations such as clicking, sliding, pressing, and the like. The transparent cover plate may be made of a rigid material such as glass, or may be made of a flexible material such as Polyimide (PI) or colorless Polyimide (Colorless Polyimide, CPI). The display panel is mainly used for displaying pictures and can be used as an interactive interface for indicating a user to perform the touch operation on the transparent cover plate. The display panel may be an OLED (Organic Light-Emitting Diode) panel for displaying an image, or an LCD (Liquid Crystal Display) panel for displaying an image. The touch panel is mainly used for responding to touch operations of a user, converting the corresponding touch operations into electrical signals and transmitting the electrical signals to the processor of the electronic device 100, so that the electronic device 100 can respond to the touch operations of the user. The foregoing is merely a simple description of the basic structure and functions of the display 110, and the specific structure and implementation principles of the display 110 may refer to the prior art, which is not repeated herein.

The housing assembly 120 may be used to conduct probe light, and may also protect electronics within the receiving space 101. As shown in fig. 3 to 4, the housing assembly 120 may include: rear case 121, cover plate 122, lens 123, bracket 124, and bezel 125. The display 110 may cover one side of the bezel 125, and the rear case 121 may cover the other opposite side of the bezel 125. The cover plate 122 may be disposed on the rear case 121, and the rear case 121 and the cover plate 122 may enclose the accommodating space 101 with the display screen 110 and the bezel 125. The lens 123 may be disposed in the receiving space 101 and may be disposed opposite to and spaced apart from the cover plate 122, which may be used to conduct the probe light. The holder 124 may also be provided in the accommodating space 101, and the holder 124 may be used to fix the lens 123 in the accommodating space 101 such that the lens 123 may be spaced apart from and disposed opposite to the cover plate 122.

The detection light emitted from the light detection assembly 130 may sequentially pass through the lens 123, the rear case 121 and the cover plate 122 to be irradiated outside the accommodating space 101, and may sequentially pass through the cover plate 122, the rear case 121 and the lens 123 to be irradiated back into the accommodating space 101 after being reflected by an object outside the accommodating space 101. Thus, when the user wears the wearable device 10 on the wrist, the light detection component 130 can radiate the detection light to the wrist of the user, and then receive the detection light reflected by the wrist of the user, so as to analyze the detection light with the information of the body tissues of the user, and realize the health detection function of the wearable device 10.

Referring to fig. 5 to 7, fig. 5 is a schematic view of a partial cross-sectional structure of the housing assembly 120 and the light detecting assembly 130 along v-v in fig. 3, fig. 6 is a schematic view of the rear case 121 in fig. 4, and fig. 7 is a schematic view of the cover plate 122 in fig. 4.

The rear case 121 may be covered on the other opposite side of the rim 125, which may be assembled with the rim 125 by means of adhesive and/or snap. The rear case 121 may be used for mounting and protecting the electronic devices in the accommodating space 101, and may be made of plastic or ceramic. Meanwhile, since the rear case 121 is generally directly exposed to the external environment, the rear case 121 may have a certain wear-resistant, corrosion-resistant, scratch-resistant property, or one or more layers of functional materials for wear-resistant, corrosion-resistant, scratch-resistant may be coated on the outer surface of the rear case 121 facing away from the accommodating space 101. In some embodiments, the material of the rear housing 121 may be not limited to plastic or ceramic, and may be selected according to design requirements, which is not limited in this embodiment.

In order to enable the detection light to propagate through the rear case 121, the rear case 121 may be further provided with a through hole 1211. As shown in fig. 5 to 6, the through hole 1211 may be opened at a central region of the rear case 121, and the through hole 1211 may be a circular hole. Compared with the scheme of carrying out light transmission by making a partial transparent design on the rear shell 121, the rear shell 121 is provided with the through holes 1211 for light transmission, so that the material of the rear shell 121 is not limited, and the problem that detection light rays are fleeing inside the rear shell 121 due to the fact that the rear shell 121 is made of a light-transmitting material can be avoided. Further, the cover plate 122 may cover the through hole 1211 to ensure sealability of the wearable device 10. The lens 123 may be disposed within the through hole 1211 to mount the lens 123 using the through hole 1211, reducing the stacking thickness of the case assembly 120. After passing through the lens 123, the light emitted by the light detecting component 130 can be irradiated onto the cover 122 through the through hole 1211, and can be conducted to the outside of the accommodating space 101 through the cover 122. Similarly, the detection light reflected back by the user's body may also be returned by the same route and received by the light detection assembly 130. In some embodiments, instead of being assembled as two separate parts, the rear case 121 and the cover plate 122 may be integrally formed by corresponding processes, i.e., the rear case 121 and the cover plate 122 may be of a unitary structure. Meanwhile, the shape of the through hole 1211 may be not limited to a circular hole, and the specific shape thereof may be adjusted according to design requirements, which is not limited in this embodiment.

The cover plate 122 may be disposed at a side of the rear case 121 facing away from the accommodating space 101, and the cover plate 122 may cover the through hole 1211, which may be used to conduct the detection light emitted from the light detecting assembly 130. For example, the cover 122 may be transparent, and the cover 122 may be made of glass or sapphire so that the probe light may be conducted through the cover 122. Of course, in order to reduce interference of the stray light on the light detecting component 130 and to block the internal structure of the wearable device 10, the cover 122 may be partially transparent and light-shielding may be performed in the area where light transmission is not required. As shown in fig. 5 and 7, the cover plate 122 may be provided with a light-transmitting region 1221 and a light-non-transmitting region 1222. The light-transmitting area 1221 may be an area that is not light-shielded from the cover 122, and the detection light may be transmitted through the cover 122 by the light-transmitting area 1221. The opaque region 1222 may be a region of the cover plate 122 that is masked. For example, the surface of the cover plate 122 adjacent to the receiving space 101 may be coated with ink or silk-screened black to block light to form the opaque region 1222. In some embodiments, in addition to the light shielding process, a reflective coating or plating layer may be disposed on an outer surface of the cover plate 122 facing away from the receiving space 101 to reflect external parasitic light. Furthermore, in some embodiments, the cover plate 122 and the rear housing 121 may be of unitary construction, in addition to being separate components. That is, the cover plate 122 may also be a part of the rear case 121.

The light transmitting region 1221 may include: a first light-transmitting region 12211 and a second light-transmitting region 12212. The detection light emitted from the light detection component 130 can be conducted to the outside of the accommodating space 101 through the first light-transmitting area 12211, and the detection light reflected by the body of the user can be conducted to the inside of the accommodating space 101 through the second light-transmitting area 12212. The first light-transmitting region 12211 may be disposed in a central region of the cover plate 122, and the second light-transmitting region 12212 may be disposed adjacent to the first light-transmitting region 12211. Meanwhile, the number of the second light-transmitting areas 12212 may be plural, and the plurality of second light-transmitting areas 12212 may be disposed around the first light-transmitting area 12211 so as to transmit the reflected detection light. As shown in fig. 7, the number of the second light-transmitting areas 12212 may be four, and the four second light-transmitting areas 12212 may be distributed in four positive directions of the first light-transmitting area 12211. Of course, the number of the second light transmitting areas 12212 may be not limited to four, but may be two, three, five, or more, as long as the light detecting assembly 130 is provided with the same number of light receiving devices. In addition, the arrangement of the first light-transmitting area 12211 and the second light-transmitting area 12212 may be adjusted according to design requirements, which is not limited in this embodiment.

The terms "first," "second," "third," and the like in this application are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defining "a first", "a second", and "a third" may explicitly or implicitly include at least one such feature. In the description of the present application, the meaning of "plurality" means at least two, for example, two, three, etc., unless specifically defined otherwise.

Since the cover 122 is transparent, part of the detection light will emit after entering the first light-transmitting area 12211, that is, the detection light is directly transmitted to the second light-transmitting area 12212 in the cover 122, and then is emitted into the accommodating space 101 from the second light-transmitting area 12212 to be received by the light detecting assembly 130. In this way, since the detection light does not irradiate the wrist of the user, the detection light does not have the information of the body tissues of the user, and thus the detection of the light detection assembly 130 is interfered, and the detection accuracy of the light detection assembly 130 is reduced.

To improve the light channeling problem of the cover plate 122, a side of the cover plate 122 near the lens 123 may be further provided with a light blocking groove 1223. As shown in fig. 5, the light blocking groove 1223 may be formed on a side of the cover plate 122 located in the through hole 1211, and the light blocking groove 1223 may be further disposed around the first light transmitting area 12211. When the detection light enters the first light-transmitting area 12211 and is transmitted to the light-blocking groove 1223, the thickness of the cover plate 122 in the light-blocking groove 1223 is smaller than that of other positions, so that the propagation path of the detection light is changed, thereby reducing the detection light transmitted directly from the first light-transmitting area 12211 to the second light-transmitting area 12212, improving the light-channeling problem of the cover plate 122, and improving the detection accuracy of the light detection component 130. Meanwhile, the inner surface of the light blocking groove 1223 may be roughened to increase the roughness of the inner surface of the light blocking groove 1223 and reduce the probability of specular reflection of the detection light on the inner surface of the light blocking groove 1223. In addition, a coating or plating layer for shielding light may be provided on the inner surface of the light blocking groove 1223 to further reduce the probability of occurrence of blowby of the detection light.

Referring to fig. 8 to 10 in combination with fig. 5, fig. 8 is a schematic structural diagram of the lens 123 in fig. 4, fig. 9 is a schematic diagram of the transmission of the detection light in the attached state of the lens 123 and the cover 122 in fig. 5, and fig. 10 is a schematic diagram of the transmission of the detection light in the spaced state of the lens 123 and the cover 122 in fig. 5.

The lens 123 may be disposed in the accommodating space 101 and between the light detecting component 130 and the cover plate 122, and the lens 123 may also be disposed in the through hole 1211, opposite to the light-transmitting area 1221 and spaced apart from the light-transmitting area 1221, which may play a role in enhancing light condensation, so that the detection light may be transmitted into the light-transmitting area 1221 through the lens 123. As shown in fig. 5 and 8, the lens 123 may include: a first lens 1231 and a second lens 1232. The first lens 1231 may be disposed in the through hole 1211, opposite to the first light-transmitting area 12211 and spaced apart from the first light-transmitting area 12211, and may be configured to collect the detection light emitted from the light-detecting assembly 130 and transmit the detection light into the first light-transmitting area 12211, so that the detection light may be irradiated outside the accommodating space 101. The second lens 1232 may also be disposed in the through hole 1211, opposite to the second light-transmitting area 12212 and spaced apart from the second light-transmitting area 12212, and may be configured to collect the detection light reflected by the wrist of the user conducted by the second light-transmitting area 12212 and conduct the detection light into the accommodating space 101, so that the light detecting assembly 130 may receive the detection light with the information of the body tissue of the user. In some embodiments, the lens 123 may be disposed outside the through hole 1211, and the lens 123 may be disposed opposite to and spaced apart from the light-transmitting region 1221. Meanwhile, the lens 123 may be not limited to the lens for enhancing the focusing, but may be a filter lens, a spherical/aspherical lens, a free-form lens, or the like to achieve other functions such as filtering, which is not limited in this embodiment.

Specifically, the first lens 1231 and the second lens 1232 may be a film sheet having light collecting capability, or may be fresnel lenses. Meanwhile, the number of the second lenses 1232 may be plural, and the plurality of second lenses 1232 may be further provided with the first lenses 1231. As shown in fig. 8, the number of the second lenses 1232 may be four, and the four second lenses 1232 may be distributed in four positive directions of the first lens 1231 to correspond to the four second light-transmitting areas 12212. Of course, the number of the second lenses 1232 may be not limited to four, but may be two, three, five or more, and only the number of the second lenses 1232 is required to match the number of the second light-transmitting areas 12212. Accordingly, the arrangement of the first lens 1231 and the second lens 1232 may also be changed along with the change of the arrangement of the first light-transmitting area 12211 and the second light-transmitting area 12212, which is not limited in this embodiment.

As long-term researches of the inventor find that, when the first lens 1231 is attached to the first light-transmitting area 12211, the refractive angle generated by the incident of the detection light into the first light-transmitting area 12211 by the first lens 1231 is often larger, so that the detection light is more prone to light channeling. As shown in fig. 9, solid arrows may represent the conducting paths of the detection light, and the refraction angle generated by the detection light when the detection light is incident into the first light-transmitting region 12211 through the first lens 1231 is generally larger. Specifically, when the cover plate 122 is made of glass, the angle value of the refraction angle θ is at most about 90 °. When the cover 122 is made of sapphire, the angle value of the refraction angle β is at most about 64 °. Thus, when the detection light enters the first light-transmitting region 12211, the larger refraction angle may make the detection light diffuse more easily in the cover 122 to generate a light channeling phenomenon, thereby reducing the detection accuracy of the light detection assembly 130.

Therefore, in the present embodiment, the first lens 123 and the first light-transmitting area 12211 are disposed opposite to each other at a distance from each other, so that an air gap is formed between the first lens 123 and the first light-transmitting area 12211, thereby reducing the angle value of the refraction angle generated by the incident detection light into the first light-transmitting area 12211 by using the air refraction principle, and improving the channeling phenomenon of the detection light. As shown in fig. 10, since a gap exists between the first lens 123 and the first light-transmitting area 12211, when the detection light enters the gap through the first lens 1231, refraction occurs in the gap, and then the detection light enters the first light-transmitting area 12211, so that the refraction angle generated by the detection light entering the first light-transmitting area 12211 is generally smaller. Specifically, when the interval H between the first lens 1231 and the first light-transmitting region 12211 is 0.1mm and the cover plate 122 is made of glass, the angle value of the refraction angle α is at most about 42 °. When the interval H between the first lens 1231 and the first light-transmitting region 12211 is 0.1mm and the cover plate 122 is made of sapphire, the angle value of the refraction angle α is at most about 35 °.

In this way, compared with the scheme of attaching the first lens 1231 and the first light-transmitting area 12211, the first lens 1231 and the first light-transmitting area 12211 are spaced to form a gap, which can play a role in converging the detection light, so as to reduce the angle value of the refraction angle generated by the injection of the detection light into the first light-transmitting area 12211, reduce the diffusion of the detection light in the cover plate 122, improve the light channeling problem of the detection light, and improve the detection precision of the light detection assembly 130. Accordingly, the second lens 1232 and the second light-transmitting area 12212 are disposed at an interval similar to those of the first lens 1231 and the first light-transmitting area 12211, and more detection light can be converged by using the gap to enter the second lens 1232, so that the second lens 1232 can transmit more detection light with the body tissue information of the user to the accommodating space 101 to be received by the light detection assembly 130, thereby improving the detection accuracy of the light detection assembly 130.

In some embodiments, the distance H between the lens 123 and the light transmitting region 1221 may be not limited to 0.1mm, but may range from 0.05mm to 0.15mm, and may be 0.05mm, 0.08mm, 0.12mm, or 0.15mm. Thus, the thickness of the stack of the housing assembly 120 is not excessively increased while improving the channeling phenomenon. In addition, the optical paths of the detection light in fig. 9 and 10 are only schematically illustrated, and the detection light is refracted or reflected multiple times after entering the entrance lens 123 and the light-transmitting area 1221, and the specific optical paths thereof are not shown in fig. 9 and 10.

Referring to fig. 11 to 14 in combination with fig. 4 to 5, fig. 11 is a schematic structural view of the bracket 124 in fig. 5, fig. 12 is a schematic structural view of the connection of the lens 123 and the bracket 124 in fig. 4, fig. 13 is a partially enlarged view of fig. 5 at a, and fig. 14 is a partially enlarged view of fig. 5 at B.

The bracket 124 may be disposed in the receiving space 101 between the light detecting assembly 130 and the cover plate 122, and may be used to mount the lens 123 to fix the lens 123 in the through hole 1211 such that the lens 123 may be disposed opposite to and spaced apart from the cover plate 122. As shown in fig. 5 and 11, the bracket 124 may be disposed in the through hole 1211, and the bracket 124 may be connected with the rear case 121 such that the bracket 124 may be fixed in the through hole 1211 through the rear case 121. The bracket 124 may include: a mounting plate 1241 and a connecting plate 1242. The mounting plate 1241 may be disposed within the through hole 1211, and the mounting plate 1241 may be disposed opposite to and spaced apart from the cover plate 122. The connection plate 1242 may be disposed at a side of the mounting plate 1241 facing away from the cover plate 122, and the connection plate 1242 may be connected with the rear case 121 such that the mounting plate 1241 may be fixed within the through hole 1211. In this embodiment, the material of the bracket 124 may be metal, so that the bracket 124 may also function as an antenna. In some embodiments, the material of the stand 124 may also be a rigid plastic to reduce the weight of the wearable device 10. Of course, the support 124 may be made of other materials with a certain structural strength, which is not limited in this embodiment.

The shape of the mounting plate 1241 may be adapted to the shape of the through hole 1211, and the mounting plate 1241 may be used to mount the lens 123. As shown in fig. 5, 11, and 13, the mounting plate 1241 may be provided with a recess 12411 formed to be recessed toward a direction away from the cover plate 122, and the recess 12411 may be recessed on the mounting plate 1241 to form a groove 12412. The groove 12412 may be used to mount the lens 123 to ensure that there is sufficient clearance between the lens 123 and the cover plate 122 to form an air gap. Accordingly, the recess 12411 may further be provided with a light hole 12413, and the lens 123 may cover the light hole 12413, so that the detection light may be emitted into the lens 123 through the light hole 12413. In some embodiments, if the through hole 1211 has enough space to enable the lens 123 disposed on the mounting plate 1241 to be spaced from the cover plate 122, the design of the recess 12411 may be omitted, and the lens 123 may be directly covered on the light-transmitting hole 12413.

Further, in order to fit the first light-transmitting region 12211 and the second light-transmitting region 12212, the concave portion 12411 may be provided with two. As shown in fig. 11 to 12, the recess 12411 may include: a first recess 12411a and a second recess 12411b. The first concave portion 12411a may be disposed opposite to the first light-transmitting region 12211, and the second concave portion 12411b may be disposed opposite to the second light-transmitting region 12212. The number of the second concave portions 12411b may be plural, and the plurality of the second concave portions 12411b may be further disposed around the first concave portion 12411 a. The number of the second concave portions 12411b may be four, and the four second concave portions 12411b may be distributed in four positive directions of the first concave portion 12411a, so as to correspond to the four second light-transmitting areas 12212. Of course, the number of the second concave portions 12411b may be not limited to four, but may be two, three, five or more, and only the number of the second concave portions 12411b is required to be matched with the number of the second light-transmitting areas 12212. Accordingly, the arrangement of the first concave portion 12411a and the second concave portion 12411b may also be changed along with the change of the arrangement of the first light-transmitting area 12211 and the second light-transmitting area 12212, which is not limited in this embodiment.

The light transmission hole 12413 may include: the first light transmission holes 12413a and the second light transmission holes 12413b. The first recess 12411a may be provided with a first light-transmitting hole 12413a, and the second recess 12411b may be provided with a second light-transmitting hole 12413b. The first lens 1231 may be disposed in the recess 12412 formed by the first recess 12411a and cover the first light hole 12413a. The second lens 1232 can be disposed in the groove 12412 formed by the second concave portion 12411b and cover the second light-transmitting hole 12413b. In this manner, the first lens 1231 and the second lens 1232 may be fixed in the through hole 1211 by the mounting plate 1241, opposite to and spaced apart from the cover plate 122. Meanwhile, the detection light emitted from the light detecting assembly 130 may be irradiated into the first lens 1231 through the first light transmitting hole 12413a, and then be conducted to the outside of the accommodating space 101 through the first lens 1231 and the first light transmitting area 12211, and irradiated onto the wrist of the user. Accordingly, the detection light reflected back from the wrist of the user may sequentially pass through the second light-transmitting area 12212, the second lens 1232 and the second light-transmitting hole 12413b to be irradiated into the accommodating space 101 and received by the light detecting assembly 130.

Because the recess 12411 may be stepped on a side of the mounting plate 1241 facing away from the cover plate 122, such that a side of the mounting plate 1241 facing away from the cover plate 122 is uneven, the housing assembly 120 may also be provided with the filler 126 in order to maintain the flatness of the side of the mounting plate 1241 facing away from the cover plate 122. As shown in fig. 4 to 5 and 13, the filling member 126 may be disposed on a side of the mounting plate 1241 facing away from the cover plate 122, and the filling member 126 may be disposed flush with a side of the recess 12411 facing away from the cover plate 122, so that the filling member 126 may fill a step formed on a side of the recess 12411 facing away from the cover plate 122 of the mounting plate 1241, so as to facilitate a light shielding structure between the mounting plate 1241 and the light detecting assembly 130. Specifically, the filler 126 may be a PET (polyethylene glycol terephthalate, polyethylene terephthalate) film. Of course, the filler 126 may not be limited to a PET film, and the material thereof may be selected according to the design requirement, and the filler 126 may be used only to fill the step formed in the mounting plate 1241 by the recess 12411.

Since the mounting plate 1241 is spaced from the cover plate 122, a corresponding gap is also formed therebetween. In order to prevent the light emitted from the first lens 1231 from entering the second light-transmitting region 12212 through the gap, the housing assembly 120 may further be provided with a first light shielding member 127. As shown in fig. 4 to 5 and 13, the first light shielding member 127 may be disposed between the mounting plate 1241 and the cover plate 122 and in contact with the mounting plate 1241 and the cover plate 122, respectively, and the front projection of the first light shielding member 127 on the mounting plate 1241 may also be disposed around the front projection of the first lens 1231 on the mounting plate 1241. In this way, the first light shielding member 127 can enclose a closed cavity between the first lens 1231 and the first light-transmitting area 12211 to shield the detection light emitted from the first lens 1231 from entering the second light-transmitting area 12212 through the gap between the mounting plate 1241 and the cover plate 122. The first light shielding member 127 may be a light shielding foam, which not only can shield the detection light, but also can support the cover plate 122 and the mounting plate 1241 to play a certain role in buffering. In some embodiments, the first light shielding member 127 may be disposed between the second lens 1232 and the second light-transmitting region 12212, so as to form a closed cavity therebetween, thereby reducing the interference of the detection light between the adjacent second light-transmitting regions 12212.

In addition, since the cover 122 is generally in contact with the user's body, the housing assembly 120 may also be provided with a thermal shield 128 in order to reduce the amount of heat transferred from the user's body by the cover 122. As shown in fig. 4 to 5 and 13, the heat insulating member 128 may be disposed at a side of the mounting plate 1241 near the cover plate 122, and the heat insulating member 128 may be disposed between the first light shielding member 127 and the mounting plate 1241. Wherein the insulation 128 may specifically be a thermal insulation film to reduce the stack thickness of the housing assembly 120 while providing thermal insulation. Meanwhile, in order to avoid the shielding of the detection light by the heat insulating member 128, the region of the heat insulating member 128 opposite to the light transmission hole 12413 is further provided with a avoidance hole 1281, so that the detection light can be conducted to the light transmission area 1221 of the cover plate 122 through the avoidance hole 1281.

Optionally, the insulation 128 may also be subjected to a corresponding shading treatment, such that the insulation 128 may have shading capability. In this way, the design of the first shade 127 can also be omitted, simply by contacting the cover plate 122 on the side of the insulating member 128 facing away from the mounting plate 1241. Of course, the first light shielding member 127 may also be doped with a material having heat insulating property, so that the first light shielding member 127 may have heat insulating capability, thereby eliminating the design of the heat insulating member 128.

The connection plate 1242 may be disposed at a side of the mounting plate 1241 facing away from the cover plate 122, and the connection plate 1242 may be located at an edge area of the mounting plate 1241, which may be used to connect with the rear case 121. As shown in fig. 5, 11 and 14, the connection plate 1242 may be disposed outside the through hole 1211 in a protruding manner, and the connection plate 1242 may be disposed at a side of the rear case 121 facing away from the cover plate 122 and connected with the rear case 121, so that the bracket 124 may be fixed inside the through hole 1211. For example, the rear case 121 may be provided with a protrusion 1212, the connection plate 1242 may be provided with a fitting hole 12421, and the protrusion 1212 may be disposed in the fitting hole 12421, so that the connection plate 1242 and the rear case 121 may be positionally connected. Meanwhile, in order to improve the connection strength of the two, an adhesive may be further provided between the rear case 121 and the connection plate 1242 to bond the rear case and the connection plate 1242. The number of the connection plates 1242 may be four, and the four connection plates 1242 may be uniformly distributed in four positive directions of the mounting plate 1241. Of course, the number of the connection plates 1242 may be not limited to four, but may be three, five or six, and the specific number may be adjusted according to the design requirement, which is not limited in this embodiment.

In some embodiments, the connection plate 1242 may also be disposed on a side of the mounting plate 1241 near the cover plate 122, and the connection plate 1242 may also be disposed outside the through hole 1211 in a protruding manner and disposed between the rear case 121 and the cover plate 122. That is, the connection plate 1242 may be connected to a side of the rear case 121 facing away from the receiving space 101, and the cover plate 122 may be disposed at a side of the connection plate 1242 facing away from the rear case 121. Furthermore, in other embodiments, the mounting plate 1241 and the rear case 121 may also be integrally formed by an in-mold injection process, so that the design of the connection plate 1242 may be omitted, thereby reducing the weight of the wearable device 10.

As shown in fig. 2 to 4, the display screen 110 may be covered on one side of the frame 125, the rear housing 121 may be covered on the other opposite side of the frame 125, and the rear housing 121 and the frame 125 may enclose to form an open structure, and the display screen 110 may be covered on the open structure, so that the three may enclose together to form the accommodating space 101. The receiving space 101 may be used to mount other electronic components such as a battery, a camera, a speaker, a microphone, etc. required for the wearable device 10, in addition to the aforementioned light detection assembly 130 and lens 123. The display 110 and the rear case 121 may be fixedly connected to the frame 125 by means of an adhesive and/or a connection board. Of course, the connection manner of the display 110 and the rear case 121 is not limited thereto, and the present embodiment is not limited thereto. All directional indications (such as up, down, left, right, front, back … …) in the embodiments of the present application are merely used to explain the relative positional relationship, movement, etc. between the components in a particular gesture (as shown in the drawings), and if the particular gesture changes, the directional indication changes accordingly.

The rim 125 may be similar in shape to a square having rounded corners, and the rim 125 may be used to mount the electronic device of the electronic apparatus 100 to secure the electronic device within the receiving space 101. For example, the speaker of the electronic device 100 may be fixed on the frame 125, and the frame 125 may be further provided with a corresponding sound hole, so as to communicate with the speaker and the outside of the accommodating space 101, so that the speaker may make sound through the sound hole. Also, opposite sides of the border 125 may be used in connection with the strap 200. For example, opposite sides of the rim 125 may be provided with a raw ear hole, and one end of the strap 200 may be provided with a raw ear needle, such that the strap 200 can be detachably connected with the rim 125 through the raw ear needle. In addition, the material of the frame 125 may be metal or rigid plastic, or may be formed by metal and rigid plastic together. For example, the frame 125 may be divided into an inner case and an outer case, the inner case may be made of hard plastic, the outer case may be made of metal, and the inner case and the outer case may be integrally formed through an in-mold injection process. Thus, not only the frame 125 has higher structural strength, but also the weight of the frame 125 can be reduced.

Since the frame 125 is generally directly exposed to the external environment, the frame 125 may have a certain wear-resistant, corrosion-resistant, scratch-resistant property, or one or more layers of functional materials for wear-resistant, corrosion-resistant, scratch-resistant may be coated on the outer surface of the frame 125 facing away from the accommodating space 101. In some embodiments, the connection between the frame 125 and the strap 200 is not limited to the aforementioned ear-generating pin, and other detachable connection methods may be used for the two, or the two may be fixedly connected and not detachable. Meanwhile, the shape of the frame 125 may be a circle, an ellipse or other shapes, and the specific shape thereof may be adjusted according to the design requirement, which is not limited in this embodiment.

It is understood that the rear case 121, the cover 122 and the frame 125 may be formed as a single piece. Meanwhile, the rear case 121, the cover 122, and the bezel 125 may also constitute a housing 1201 of the wearable device 10, and the housing 1201 is not limited to include only the rear case 121, the cover 122, and the bezel 125, but may also include a decorative member or the like provided on the rear case 121 or the bezel 125. Furthermore, in some embodiments, the bezel 125 and the back case 121 may be an integral structure in addition to being two separate components, such that the housing 1201 may include only the back case 121 and the cover plate 122. The terms "comprising" and "having" and any variations thereof, are intended to cover a non-exclusive inclusion. For example, a process, method, system, article, or apparatus that comprises a list of steps or elements is not limited to only those listed steps or elements but may include other steps or elements not listed or inherent to such process, method, article, or apparatus.

Referring to fig. 15 in conjunction with fig. 5, fig. 15 is a schematic structural diagram of the light detecting component 130 in fig. 3.

The light detection component 130 may be disposed in the accommodating space 101, and may be configured to emit detection light and receive the detection light reflected by the body of the user for analysis, so as to implement the health detection function of the wearable device 10. As shown in fig. 5 and 15, the light detection assembly 130 may include: a circuit board 131, a light emitting member 132, a light receiving member 133, and a second light shielding member 134. The circuit board 131 may be disposed in the accommodating space 101, and the circuit board 131 may also be covered on the through hole 1211, and disposed opposite to and spaced apart from the mounting board 1241. The light emitting member 132 may be disposed on a side of the circuit board 131 near the mounting board 1241, and the light emitting member 132 may be disposed opposite to the first lens 1231, which may be used to emit the detection light, so that the detection light may be emitted out of the accommodating space 101 through the first lens 1231 and the first light transmitting area 12211. The light receiving element 133 may also be disposed on a side of the circuit board 131 near the mounting board 1241, and the light receiving element 133 may be disposed opposite to the second lens 1232, which may be used to receive the detection light, so that the detection light reflected by the body of the user can be received by the light receiving element 133 after passing through the second light-transmitting area 12212 and the second lens 123. Meanwhile, in order to be adapted to the second light-transmitting region 12212, the number of the light-receiving members 133 may be four, and the four light-receiving members 133 may be disposed around the light-emitting member 132 and distributed in four positive directions of the light-emitting member 132. Of course, as the number and arrangement of the second light-transmitting regions 12212 are changed, the number and arrangement of the light-receiving members 133 may be changed.

The second light shielding member 134 may also be disposed on a side of the circuit board 131 near the mounting plate 1241, and a side of the second light shielding member 134 facing away from the circuit board 131 may also be in contact with the mounting plate 1241 and disposed around the light emitting member 132 and the light receiving member 133, respectively. In this way, the second light shielding member 134 may enclose a closed cavity between the light emitting member 132 and the first lens 1231, and also enclose a closed cavity between the light receiving member 133 and the second lens 1232, so as to prevent the light emitted by the light emitting member 132 from directly being received by the light receiving member 133 without entering the first lens 1231, and improve the detection accuracy of the wearable device 10. The second light shielding member 134 may be a light shielding foam, which not only can shield the detection light, but also can support the mounting board 1241 and the circuit board 131 to play a certain role in buffering. In addition, in order to save material, the second light shielding member 134 may be disposed around the light emitting member 132 and the three light receiving members 133, respectively, and the remaining one light receiving member 133 may not be disposed around.

It will be appreciated that since the filler 126 fills the side of the mounting plate 1241 facing away from the cover plate 122, i.e., the side in contact with the second light-shielding member 134, the second light-shielding member 134 is in contact with the filler 126 when the mounting plate 1241 is in contact. Of course, if the mounting plate 1241 has a sufficient contact area, the second light shielding member 134 may be in contact with only the mounting plate 1241.

In some embodiments, the light detection assembly 130 may also be provided with conductive foam 135. As shown in fig. 15, the conductive foam 135 may also be disposed on a side of the circuit board 131 near the mounting board 1241, and a side of the conductive foam 135 facing away from the circuit board 131 may also contact the mounting board 1241, so as to support the mounting board 1241 and the circuit board 131, and also electrically connect the circuit board 131 and the mounting board 1241 to perform a grounding function.

Referring to fig. 16 to 20, fig. 16 is a schematic view of a partial cross-sectional structure of the housing assembly 120 and the light detection assembly 130 in fig. 3 in another embodiment along v-v, fig. 17 is a partially enlarged view at C in fig. 16, fig. 18 is a partially enlarged view at D in fig. 16, fig. 19 is a partially enlarged view at C in fig. 16 in another embodiment, and fig. 20 is a partially enlarged view at D in fig. 16 in another embodiment.

In some embodiments, other components may be used to secure the lens 123 in addition to securing the lens 123 with the bracket 124. As shown in fig. 16 to 18, the electronic device 10 may further be disposed on the third light shielding member 1243, and the third light shielding member 1243 may be disposed on a side of the cover plate 122 near the mounting plate 1241, which may be adhered and fixed to the cover plate 122 by an optical adhesive. The third light shielding member 1243 may be located in the through hole 1211, and the shape of the third light shielding member 1243 may be adapted to the second light shielding member 134. The side of the second light shielding member 134 facing away from the circuit board 131 may contact the side of the third light shielding member 1243 facing away from the cover plate 122, such that the second light shielding member 134 and the third light shielding member 1243 may be enclosed to form a channel L1. Accordingly, the first lens 1231 may be disposed between the second light shielding member 134 and the third light shielding member 1243, and located in the channel L1, which may be adhered and fixed to the second light shielding member 134 or the third light shielding member 1243 by an adhesive. The second lens 1232 may also be disposed between the second light shielding member 134 or the third light shielding member 1243 and located in the channel L1, and may also be adhered and fixed to the second light shielding member 134 and the third light shielding member 1243 by an adhesive. In this way, the first lens 1231 and the second lens 1232 can still be fixed in the through hole 1211, and the first lens 1231 and the second lens 1232 are both opposite to the cover plate 122 and are disposed at a distance. Specifically, the third light shielding member 1243 may be a light shielding foam.

In some embodiments, the second light shield 134 and the third light shield 1243 may also be a unitary structure. That is, the bracket 124 may also be the second light shielding member 134, and a side of the second light shielding member 134 facing away from the circuit board 131 may directly contact the cover plate 122, thereby forming a channel L1 around between the cover plate 122 and the circuit board 131 to mount the first lens 1231 and the second lens 1232. Furthermore, in some embodiments, the design of the third shade 1243 may also be preserved. As shown in fig. 19 to 20, a side of the second light shielding member 134 facing away from the circuit board 131 may directly contact the cover plate 122, and the second light shielding member 134 may be further disposed around the third light shielding member 1243 so as to form a channel L1 together with the third light shielding member 1243. Accordingly, the first lens 1231 and the second lens 1232 may be disposed on a side of the third light shielding member 1243 facing away from the cover plate 122. In this way, the first lens 1231 and the second lens 1232 can still be fixed in the through hole 1211, and the first lens 1231 and the second lens 1232 are both opposite to the cover plate 122 and are disposed at a distance.

Referring to fig. 21 to 23, fig. 21 is a schematic view showing a partial cross-sectional structure of the housing assembly 120 and the light detecting assembly 130 in fig. 3 along the line v-v in still another embodiment, fig. 22 is a schematic view showing a structure of the rear case 121 in fig. 21, and fig. 23 is a schematic view showing a partial cross-sectional structure of the housing assembly 120 and the light detecting assembly 130 in fig. 3 along the line v-v in one embodiment.

Alternatively, instead of fixing the lens 123 inside and outside the accommodating space 101 using the bracket 124, the lens 123 may be fixed inside the accommodating space 101 using the rear case 121 and disposed opposite to and at a distance from the cover plate 122. As shown in fig. 21 to 22, the rear case 121 may still be provided with a through hole 1211 for light transmission, which is different from the previous embodiment in that the through hole 1211 formed in the rear case 121 may be adaptively arranged with the lens 123. For example, the through hole 1211 may include: a first through hole 12111 and a second through hole 12112. Wherein the first through hole 12111 may be disposed opposite to the first light-transmitting region 12211, and the second through hole 12112 may be disposed opposite to the second light-transmitting region 12212. Meanwhile, the number and arrangement of the second through holes 12112 may also correspond to those of the second light-transmitting areas 12212. Accordingly, the first lens 1231 may be disposed at a side of the rear case 121 facing away from the cover plate 122, and cover the first through hole 12111. The second lens 1232 may be disposed on a side of the rear case 121 facing away from the cover plate 122, and covers the second through hole 12112. In this way, not only can the lens 123 be fixed in the accommodation space 101 by the rear case 121, it is also possible to form an air gap between the lens 123 and the light-transmitting region 1221 by using the through hole 1211, thereby reducing the refractive angle of the detection light.

In some embodiments, the first lens 1231 and the second lens 1232 may be not limited to be disposed on the side of the rear case 121 facing away from the cover plate 122. As shown in fig. 23, the first lens 1231 and the second lens 1232 may be disposed at a side of the rear case 121 near the cover plate 122. Accordingly, in order to secure an air gap between the lens 123 and the light-transmitting area 1221, an escape groove communicating with the through hole 1211 may be opened at a side of the rear case 121 toward the cover plate 122, and the lens 123 may be disposed in the escape groove to absorb the thickness of the lens 123 using the depth of the escape groove. Of course, in addition to the manner of providing the escape groove, a spacer may be provided between the rear case 121 and the cover plate 122 to expand the interval between the rear case 121 and the cover plate 122, thereby ensuring a sufficient air gap between the lens 123 and the light-transmitting area 1221.

In the housing assembly 120 provided in the embodiment of the present application, the light-transmitting area 1221 is disposed on the housing 1201, the lens 123 is disposed in the housing 1201, and the lens 123 is located at a side of the light-transmitting area 1221 at intervals, so that a gap can be formed between the lens 123 and the light-transmitting area 1221 of the cover plate 122. In this way, the propagation path of the detection light emitted from the light detection element 130 through the lens 123 can be changed by using the principle of air refraction in the gap, so that the refraction angle of the detection light emitted into the light-transmitting area 1221 via the lens 123 is reduced. Compared with the scheme of attaching the lens 123 and the housing 1201, the method can reduce the occurrence of the light channeling phenomenon of the detection light and improve the detection accuracy of the light detection assembly 130.

The foregoing description is only a partial embodiment of the present application, and is not intended to limit the scope of the present application, and all equivalent devices or equivalent process transformations made by using the descriptions and the drawings of the present application, or direct or indirect application to other related technical fields, are included in the patent protection scope of the present application.
