The technical solution of the present invention will be further described with reference to the following examples and drawings.

Please refer to fig. 1, an embodiment of the present invention discloses an apron, this apron 100 can be applied to intelligent wearing equipment such as intelligent wrist-watch, intelligent bracelet. The intelligent wearable device is provided with a photoplethysmograph (PPG for short), the photoplethysmograph comprises a light emitting device and a photoelectric sensing device which are arranged at intervals, light rays can be emitted to a human body through the light emitting device, reflected light after being absorbed by blood and tissues of the human body is detected through the photoelectric sensing device, heart rate change, blood oxygen change or body temperature change of a wearer are detected, and accordingly monitoring of human health indexes is achieved. Namely, the light emitting device can emit red light, green light, infrared light and the like, so that the monitoring of a plurality of health indexes such as heart rate, blood oxygen, body temperature and the like is realized by matching with the photoelectric sensing device.

Referring to fig. 2 to 5, the cover plate 100 may include a main cover plate portion 1 and a light transmission member 2, the main cover plate portion 1 is used for installing the photoplethysmograph on the intelligent wearable device, the main cover plate portion 1 is provided with a through installation groove 11, the light transmission member 2 is arranged in the installation groove 11, the light transmission member 2 includes a first light transmission portion 21 and a second light transmission portion 22 which are integrally formed, the first light transmission portion 21 is used for being arranged corresponding to the light emitting device, the second light transmission portion 22 is used for being arranged corresponding to the photoelectric sensing device, so that light emitted by the light emitting device can be irradiated to a human body through the first light transmission portion 21, and light absorbed by blood and tissue of the human body can be reflected to the photoelectric sensing device through the second light transmission portion 22 to detect heart rate change, blood oxygen change or body temperature change of the wearer.

In the apron 100 that this application provided, first printing opacity portion 21 that will correspond light emitting device and the second printing opacity portion 22 that corresponds photoelectric sensing device form a holistic printing opacity part 2 through the mode that adopts integrated into one piece, adopt like this one advance to glue some alright processing and form first printing opacity portion 21 and second printing opacity portion 22, and need not to adopt a plurality of glue some, so, adopt the technical scheme of the utility model, can reduce the glue some of advancing of first printing opacity portion 21 and second printing opacity portion 22, need not to reserve great design space like this, thereby be favorable to making the shared whole space of first printing opacity portion 21 and second printing opacity portion 22 less, and then be favorable to realizing the miniaturized design of photoplethysmograph ware, so that photoplethysmograph ware can the miniaturized intelligent wearing equipment of adaptation.

Note that the integral provision of first light transmission section 21 and second light transmission section 22 means that: the first light transmission part 21 and the second light transmission part 22 are connected into a whole and are not easy to be detached. And the first light transmission part and the second light transmission part are connected into a whole, which may include but is not limited to: during processing and manufacturing, the first light transmission part 21 and the second light transmission part 22 are formed by injection molding, and then the first light transmission part 21 and the second light transmission part 22 are formed into a whole which is not easy to split in a mode of gluing or injection molding again; alternatively, the first translucent portion 21 and the second translucent portion 22 are integrally molded to form an integral structure.

In some embodiments, the main cover portion 1 and the transparent member 2 may be formed as a single body, which means that: the main cover 1 and the translucent member 2 are connected to each other and are not easily detached. The main cover 1 and the transparent member 2 are integrally connected to each other, and may include, but are not limited to: during processing and manufacturing, the main cover plate part 1 and the transparent part 2 can be formed by injection molding, and then the main cover plate part 1 and the transparent part 2 can be formed into a whole which is not easy to be detached by means of viscose or injection molding again; alternatively, the main cover 1 and the transparent member 2 are integrally molded to form an integral structure.

In order to avoid the problem of light leakage between the light emitting device and the photoelectric sensing device and because the main cover plate 1 does not need to transmit light, the material of the main cover plate 1 may be opaque, and the material of the light transmitting member 2 needs to be transparent in order to realize the light transmitting function, so the materials of the main cover plate 1 and the light transmitting member 2 are usually different, and the integral molding of the main cover plate 1 and the light transmitting member 2 can be realized by adopting a two-color injection molding mode. In the present invention, the main cover plate 1 and the transparent member 2 are integrally molded by two-shot molding, and the transparent member 2 is usually injection molded and the main cover plate 1 is then injection molded during the injection molding process, so that the first outer peripheral surface 210 of the first transparent portion 21 and the first inner sidewall surface 11a of the mounting groove 11 are inclined surfaces that match each other, and the second outer peripheral surface 220 of the second transparent portion 22 and the second inner sidewall surface 11b of the mounting groove 11 are inclined surfaces that match each other, in order to facilitate the mold release. The first outer peripheral surface 210 is a surface of the first light-transmitting portion 21 attached to the mounting groove 11, and the first inner sidewall surface 11a is a surface of the mounting groove 11 attached to the first light-transmitting portion 21; the second outer circumferential surface 220 is a surface of the second translucent portion 22 that is attached to the mounting groove 11, and the second inner sidewall surface 11b is a surface of the mounting groove 11 that is attached to the second translucent portion 22.

It is worth mentioning that: if the main cover 1 and the transparent member 2 are formed separately, the main cover 1 and the transparent member 2 may be assembled and connected by bonding, but in the assembling process, it is usually necessary to consider the connection reliability, stability and waterproof property at the joint of the main cover 1 and the transparent member 2, so a very reliable bonding process is required, which results in high cost. In contrast to the case where the main cover 1 and the light-transmitting member 2 are formed integrally, in the present application, since the joints between the main cover 1 and the light-transmitting member 2 are likely to be fused and connected together during the injection molding process, the main cover 1 and the light-transmitting member 2 can be connected together without any bonding, and therefore, the connection reliability, stability and cost are high; moreover, a gap is not always formed at the joint between the main cover plate part 1 and the light-transmitting part 2, and the sealing and waterproof performance is good and the waterproof grade is high.

In some embodiments, the main cover portion 1 may include a first pair of inner surfaces and a second pair of outer surfaces opposite to each other, the first light-transmitting portion 21 has a second pair of outer surfaces and a second pair of inner surfaces, and the second light-transmitting portion 22 has a second pair of outer surfaces and a second pair of inner surfaces, when the cover 100 is mounted on the smart wearable device, a surface of the main cover portion 1 facing the smart wearable device is the first pair of inner surfaces of the main cover portion 1, and a surface of the main cover portion 1 facing away from the smart wearable device is the first pair of outer surfaces of the main cover portion 1; one surface of the first light transmission part 21 facing the intelligent wearable device is a second pair of inner surfaces of the first light transmission part 21, and one surface of the first light transmission part 21 facing away from the intelligent wearable device is a second pair of outer surfaces of the first light transmission part 21; a surface of second light-transmitting portion 22 facing the smart wearable device is a third pair of inner surfaces of second light-transmitting portion 22, and a surface of second light-transmitting portion 22 facing away from the smart wearable device is a third pair of outer surfaces of second light-transmitting portion 22.

The mounting groove 11 penetrates the first pair of inner surfaces and the first pair of outer surfaces, and the light-transmitting member 2 is disposed in the mounting groove 11. When first light-transmitting portion 21 and second light-transmitting portion 22 are located in the mounting groove, a second pair of outer surfaces of first light-transmitting portion 21 may be flush with a first pair of outer surfaces of main cover portion 1, or a second pair of outer surfaces of first light-transmitting portion 21 is higher than the first pair of outer surfaces of main cover portion 1, that is, the second pair of outer surfaces of first light-transmitting portion 21 protrudes out of mounting groove 11, or the second pair of outer surfaces of first light-transmitting portion 21 is lower than the first pair of outer surfaces of main cover portion 1, that is, the second pair of outer surfaces of first light-transmitting portion 21 is located in mounting groove 11; likewise, the third pair of outer surfaces of second light-transmitting portion 22 may be flush with the first pair of outer surfaces of main cover portion 1, or the third pair of outer surfaces of second light-transmitting portion 22 may be higher than the first pair of outer surfaces of main cover portion 1, that is, the third pair of outer surfaces of second light-transmitting portion 22 protrudes out of mounting groove 11, or the third pair of outer surfaces of second light-transmitting portion 22 may be lower than the first pair of outer surfaces of main cover portion 1, that is, the third pair of outer surfaces of second light-transmitting portion 22 may be located inside mounting groove 11. When the second pair of outer surfaces of the first light-transmitting portion 21 is higher than the first pair of outer surfaces of the main cover portion 1, the second pair of outer surfaces and the first pair of outer surfaces may be smoothly transited; similarly, when the third pair of outer surfaces of second light-transmitting section 22 is higher than the first pair of outer surfaces of main cover 1, the third pair of outer surfaces and the first pair of outer surfaces can smoothly transition, which can improve the comfort of the fit between the outer surfaces of cover 100 and the wrist of the user.

In some embodiments, the second pair of inner surfaces of the first light transmitting portion 21 is provided with a first fresnel pattern 211, and the first fresnel pattern 211 is used to be arranged opposite to the light emitting device; a third inner surface of the second light transmitting portion 22 is provided with a second fresnel pattern 221, and the second fresnel pattern 221 is arranged to be directly opposite to the photoelectric sensing device. So, first fresnel pattern 211 can reflect and refract the light that luminescent device launched, make dispersed light can effectively assemble on the human body, and second fresnel pattern 221 can reflect and refract the light after human blood and tissue absorb, make dispersed light can effectively assemble on photoelectric sensing device, thereby can improve signal strength, make the detection sensitivity of photoplethysmograph ware high, the heart rate, blood oxygen, human health index monitoring accuracy such as body temperature is high.

For example, each of the first fresnel patterns 211 and the second fresnel patterns 221 may be composed of a plurality of toothed rings, and each of the toothed rings of the first fresnel patterns 211 may be disposed concentrically or eccentrically, and each of the toothed rings of the second fresnel patterns 221 may be disposed concentrically or eccentrically. Preferably, each tooth-shaped ring of the first fresnel pattern 211 is concentrically arranged, each tooth-shaped ring of the second fresnel pattern 221 is concentrically arranged, a pattern center point of the first fresnel pattern 211 is arranged right opposite to a center point of the light emitting device, and a pattern center point of the second fresnel pattern 221 is arranged right opposite to a center point of the photoelectric sensing device, so that the first fresnel pattern 211 and the second fresnel pattern 221 have better light band reflection and refraction effects on the spectrum.

It can be known that if a fresnel pattern is made first and then is attached to the light-transmitting portion in a manner of adhesive, if the fresnel pattern is slightly askew, the performance of the fresnel pattern is affected, and thus the performance of the light-emitting device and the photoelectric sensing device is affected, so that the difficulty of attaching the first fresnel pattern 211 is very high, and the requirement of attaching accuracy is very high. In the present application, the first fresnel patterns 211 may be integrally formed in the first light-transmitting portion 21, and the second fresnel patterns 221 may be integrally formed in the second light-transmitting portion 22, so that design difficulty and cost of the first fresnel patterns 211 and the second fresnel patterns 221 can be reduced compared to a case where the fresnel patterns and the light-transmitting portions are formed separately.

In some embodiments, in order to realize the function of monitoring the health index of the photoplethysmograph and to improve the measurement accuracy of the photoplethysmograph, the photoplethysmograph generally comprises a light emitting device and a plurality of photoelectric sensing devices, correspondingly, the light transmission part 2 comprises a first light transmission part 21 and a second light transmission part 22 with the same number as the photoelectric sensing devices, the plurality of second light transmission parts 22 are arranged in one-to-one correspondence with the plurality of light emitting devices, wherein the second light transmission part 22 may be two, three, four or more. If the plurality of second light transmission parts 22 are independent from each other and are arranged separately, each second light transmission part 22 needs to be provided with an independent glue feeding point, so that the first light transmission part 21 and the plurality of second light transmission parts 22 are integrally formed into a whole, the first light transmission part 21 and the plurality of second light transmission parts 22 can be processed and formed by adopting one glue feeding point without adopting a plurality of glue feeding points, the glue feeding points of the first light transmission part 21 and the second light transmission part 22 can be further reduced, the whole space occupied by the first light transmission part 21 and the second light transmission part 22 is smaller, the miniaturization design of the photoplethysmograph is facilitated, and the photoplethysmograph can be adapted to miniaturized intelligent wearing equipment.

Further, as shown in fig. 6, the plurality of second light transmission portions 22 may be arranged at the periphery of the first light transmission portion 21, and preferably, the plurality of second light transmission portions 22 are arranged in a ring shape, and are arranged in a linear shape compared to the plurality of second light transmission portions 22, so that the entire structure of the light transmission member 2 is more compact, the cover plate 100 meets the design requirement of miniaturization, and the miniaturization design of the photoplethysmograph is further facilitated, so that the photoplethysmograph can be adapted to a miniaturization intelligent wearable device. Moreover, because a plurality of second light-transmitting parts 22 encircle the periphery that is connected at first light-transmitting part 21, then a plurality of photoelectric sensing devices encircle the periphery that sets up at the light emitting device, make the distance between each photoelectric sensing device and the light emitting device keep roughly the same like this, and make the distance between each photoelectric sensing device and the light emitting device can both keep in suitable distance range, thereby ensure that each photoelectric sensing device homoenergetic receives by the light emitting device and through the light after human blood and tissue absorb, with the change of detection wearer's heart rate or blood oxygen change, and then realize the monitoring to human health index.

As an alternative embodiment, the mounting groove 11 may be used for accommodating the light emitting device and the photoelectric sensing device in addition to the light transmitting member 2.

In this embodiment, a first partition wall is provided in the mounting groove, the first partition wall dividing the mounting groove into a first through groove and a second through groove, wherein the first light-transmitting portion is located in the first through groove, the first through groove is used for accommodating the light-emitting device, the second light-transmitting portion is located in the second through groove, and the second through groove is used for accommodating the photoelectric sensing device. In this way, the connection between the light-transmitting member and the main cover plate part is not limited to the connection between the outer peripheral surface of the light-transmitting member and the inner side wall surface of the mounting groove, and the connection between the first partition wall and the avoiding groove can be included, so that the connection area between the light-transmitting member and the main cover plate part can be increased, and the connection stability between the light-transmitting member and the main cover plate part is improved; on the other hand, the light emitting device and the photoelectric sensing device can be separated by the first partition wall, so that the first partition wall can block light emitted by the light emitting device, and the problem of light channeling between the light emitting device and the photoelectric sensing device is solved.

As another alternative, as shown in fig. 4 to 6, the first pair of inner surfaces of the main cover plate 1 are provided with protrusions 13, the protrusions 13 are provided with receiving grooves 131 communicated with the mounting groove 11 at positions corresponding to the mounting groove 11, and the receiving grooves 131 are used for receiving the light emitting device and the photoelectric sensing device.
