DETAILED DESCRIPTION

[0023] Exemplary embodiments will be described in detail herein, with examples illustrated in the accompanying drawings. In the following description, when referring to the drawings, identical numerals in different figures represent identical or similar elements, unless otherwise indicated. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.

[0024] Currently, an increasing number of wearable devices, such as smart bracelets, are capable of monitoring users' physiological parameters, such as heart rate and blood oxygen levels. Related technologies typically employ photoplethysmography (PPG) to monitor these parameters. This technique, based on an LED light source and detector, measures the attenuated light reflected and absorbed by human blood vessels and tissues, recording the pulsation of the blood vessels and measuring the pulse wave to obtain the corresponding physiological parameters.

[0025] However, the wearable devices in the related art have the problem of poor accuracy of monitoring results when performing monitoring, which affects the user experience. For example, the wearable devices in the related art are, for example, smart bracelets, which are worn on the user's arm. The wearable device includes a shell and a physiological information detection device, the shell includes a main body and an abutment portion protruding from the main body, the physiological information detection device corresponds to the position of the abutment portion, and can detect the user's physiological information through the abutment portion. By providing the abutment portion, it is convenient to fit with the user's skin, thereby facilitating the detection of the physiological information detection device. The physiological information detection device may include, for example, a light emitting part and a light receiving part, the light emitting part is, for example, a light emitting diode, and the light receiving part is, for example, a photodiode. The light emitting diode can, for example, emit green light and red light and irradiate it onto the skin, and the photodiode receives and measures the intensity of light passing through the skin.

[0026] The blood volume in the skin changes during heartbeats. When the heart contracts, blood is pushed into the arteries, increasing the blood volume there and reducing the amount of light absorbed by that area. When the heart relaxes, blood flows back out of the arteries, reducing the blood volume there and increasing the amount of light absorbed by that area. These changes can be captured by photosensors on the skin surface, generating a time-varying light intensity signal known as a pulse waveform. The troughs and peaks in the signal correspond to the heart's contraction and diastole. The pulse waveform is typically amplified and filtered to improve the signal-to-noise ratio. Physiological parameters can then be derived from the pulse waveform.

[0027] Taking blood oxygen saturation as an example, a photoelectric sensor emits red and infrared light. The degree to which hemoglobin in the blood absorbs these light depends on its oxygenation state. By comparing the red and infrared absorption, the SpO2 (SPO2 refers to transcutaneous arterial oxygen saturation) level can be calculated, thereby obtaining the blood oxygen saturation value.

[0028] When a user wears a wearable device, the contact portion is usually in contact with the skin in an optimal fit state. At this time, not only can the physiological information detection device obtain more effective signals, thereby ensuring the accuracy of the monitoring results of the wearable device, but it also does not affect the user's wearing comfort. However, when wearing a wearable device in usage scenarios such as sports, the user's arms will swing, and when the user swings their arms, a gap will be created between the contact portion of the wearable device and the user's skin. If the gap is too large, light from the external environment will enter the gap, causing the photodiode to saturate, making it impossible to analyze effective signals, thereby reducing the accuracy of wearable device detection.

[0029] When the user wears it too tightly to avoid a gap between the contact part and the skin, on the one hand, it will affect the blood flow in the arm, resulting in a lower effective signal obtained by the photodiode. On the other hand, when the wear is too tight, the contact part will press the skin with greater force, which will easily make the skin white. The white skin will cause a certain reflection effect on the light emitted by the light-emitting diode, resulting in this part of the light being unable to penetrate the skin for detection, and will also cause the effective signal obtained by the photodiode to decrease, thereby reducing the accuracy of the wearable device detection.

[0030] In order to solve the above technical problems, the present disclosure provides a wearable device, wherein an abutting portion is provided on the shell, and the abutting portion protrudes from the main body of the shell, the physiological information detection device corresponds to the position of the abutting portion, and can detect the physiological information of the user through the abutting portion. By making the abutting portion protrude from the main body, it is convenient to fit with the user's skin, thereby facilitating the detection of the physiological information detection device. The wearable device is also provided with an elastic structure connected to the abutting portion, and the elastic structure can provide an elastic force along the protruding direction of the abutting portion to the abutting portion. In this way, under the action of the elastic structure, the abutting portion can adjust its own protrusion height from the main body according to the degree of fit between the abutting portion and the user's skin, avoiding the reduction of the accuracy of the physiological information detection device in certain usage scenarios or when the fit between the abutting portion and the user's skin is too tight, thereby effectively improving the accuracy of the monitoring results of the wearable device and enhancing the user's usage experience.

[0031] An exemplary embodiment of the present disclosure provides a wearable device, such as Figure 1As shown, the wearable device 1 includes a shell 11, an elastic structure 18 and a physiological information detection device. The shell 11 includes a main body 111 and an abutment portion 19 protruding from the main body 111. It should be noted that the abutment portion 19 protrudes from the main body 111, which means that the abutment portion 19 is located on the outside of the outer surface of the main body 111 (that is, in the direction away from the user's skin). The physiological information detection device corresponds to the position of the abutment portion 19 and can detect the user's physiological information through the abutment portion 19. Exemplarily, the light emitted by the physiological information detection device passes through the abutment portion 19 and is irradiated onto the user's skin, and the light that penetrates the skin and is reflected back passes through the abutment portion 19 and is received by the physiological information detection device. By making the abutment portion 19 protrude from the main body 111, it is convenient for it to contact with the user's skin, thereby facilitating the detection of the physiological information detection device and improving the accuracy of the monitoring results of the wearable device 1.

[0032] The elastic structure 18 is connected to the abutting portion 19, and the elastic structure 18 is used to provide elastic force to the abutting portion 19 along the protruding direction of the abutting portion 19. With this design, under the action of the elastic structure 18, the abutting portion 19 can expand and contract according to the degree of fit between the abutting portion 19 and the user's skin to adjust its own protrusion height from the main body 111. This not only avoids the formation of a gap between the abutting portion 19 and the user's skin in certain usage scenarios, and avoids the abutting portion 19 and the user's skin from fitting too tightly, which may lead to a reduction in the accuracy of the physiological information detection device, thereby effectively improving the accuracy of the monitoring results of the wearable device 1 and enhancing the user's usage experience, but also effectively improves the user's comfort when wearing the wearable device 1, thereby further enhancing the user's usage experience.

[0033] Combine Figure 1 In one embodiment, a boss structure is provided on the body 111, and the boss structure includes a top wall 112 and a side wall 113. The edge of the top wall 112 is connected to the body 111 through the side wall 113. The top wall 112 constitutes an abutment portion 19, and the physiological information detection device corresponds to the position of the top wall 112. The side wall 113 constitutes an elastic structure 18. Exemplarily, the side wall 113 is an elastic structure 18 made of a silicone material. When the abutment portion 19 fits too tightly against the user's skin, the elastic structure 18 is compressed, thereby causing the abutment portion 19 to move toward the body 111, reducing the height of the abutment portion 19 protruding from the body 111; when a gap is generated between the abutment portion 19 and the user's skin, the elastic structure 18 provides elastic force to the abutment portion 19, thereby causing the abutment portion 19 to move toward the user's skin, increasing the height of the abutment portion 19 protruding from the body 111. In this way, under the action of the elastic structure 18, the contact portion 19 can expand and contract according to the degree of contact between the contact portion 19 and the user's skin to adjust the height of the contact portion 19 protruding from the body 111. This arrangement makes the elastic structure 18 simple in structure and easy to process.

[0034] In one embodiment, the top wall 112 is made of a hard material, and the side walls 113 are made of an elastic material that constitutes the elastic structure 18. For example, the top wall 112 and the side walls 113 can be separate structures connected by a connecting structure, such as a snap-fit structure, or can be an integrated structure formed by two-color injection molding. This design ensures the structural strength of the abutment portion 19 while achieving the retractable function of the abutment portion 19, thereby preventing damage to the abutment portion 19 from being punctured, thereby effectively improving the reliability of the wearable device 1.

[0035] The top wall 112 and the side wall 113 can also be made of elastic material. With such a setting, on the one hand, the abutting portion 19 and the elastic structure 18 are both elastic, and the abutting portion 19 can achieve a telescopic function under its own action, and can also achieve a telescopic function under the action of the elastic structure 18, so that the abutting portion 19 can adjust its height protruding from the main body 111, thereby improving the accuracy of the monitoring results of the wearable device 1. On the other hand, the top wall 112 constituting the abutting portion 19 is also made of elastic material. When the abutting portion 19 contacts the user's skin, compared with hard materials, it can improve the comfort of the user when wearing the wearable device 1, thereby further improving the user's usage experience.

[0036] Combine Figure 2 In another embodiment, the body 111 is provided with a boss structure comprising a top wall 112 and side walls 113. The edge of the top wall 112 is connected to the body 111 via the side walls 113. The top wall 112 forms the abutment portion 19, and the physiological information detection device corresponds to the top wall 112. The side walls 113 are flexible in the direction in which the abutment portion 19 protrudes. It is understood that the side walls 113 being flexible in the direction in which the abutment portion 19 protrudes means that the side walls 113 can deform in this direction. This allows the abutment portion 19 to move toward the body 111 when it is too tightly against the user's skin, reducing its protrusion from the body 111. When a gap forms between the abutment portion 19 and the user's skin, the abutment portion 19 can move toward the user's skin, increasing its protrusion from the body 111. With such a configuration, the contact portion 19 can be expanded or contracted according to the degree of fit between the contact portion 19 and the user's skin to adjust the height of the contact portion 19 protruding from the main body 111 .

[0037] In one embodiment, the sidewall 113 is a retractable structure. For example, the retractable structure includes multiple retractable joints nested in series along the protruding direction of the abutment portion 19. When the abutment portion 19 fits too tightly against the user's skin, the retractable structure contracts, allowing the abutment portion 19 to move toward the body 111, reducing the height of the abutment portion 19 protruding from the body 111. When a gap is created between the abutment portion 19 and the user's skin, the retractable structure expands, allowing the abutment portion 19 to move toward the user's skin, increasing the height of the abutment portion 19 protruding from the body 111. This allows the abutment portion 19 to have a retractable function while maintaining a simple structure for wearable device 1 and facilitating processing.

[0038] In another embodiment, the side wall 113 is made of a flexible material, such as a flexible resin. In this way, while the contact portion 19 has a retractable function, it can also improve the comfort of the user when wearing the wearable device 1, thereby further improving the user's experience.

[0039] Combine Figure 2 In one embodiment, the wearable device 1 further includes a circuit board 16 disposed in the shell 11, and the physiological information detection device is disposed on the first surface of the circuit board 16 facing the top wall 112. Data transmission with the physiological information detection device is realized through the circuit board 16, thereby realizing the detection of the user's physiological information.

[0040] When sidewall 113 is flexible in the direction of projection of abutment portion 19, elastic structure 18 is disposed between the first surface and top wall 112. For example, elastic structure 18 may be a spring, one end of which is connected to the first surface and the other end to top wall 112. The spring provides elastic force to abutment portion 19 in the direction of projection. This configuration simplifies the structure of wearable device 1 and facilitates processing and assembly.

[0041] Combine Figure 1 or Figure 2In one embodiment, the physiological information detection device includes a light emitting part 12, a first light guide part 13, a light receiving part 14, and a second light guide part 15. The light emitting part 12 can be, for example, a light emitting diode, the light receiving part 14 can be, for example, a photodiode, the first light guide part 13 can be, for example, a lens, and the second light guide part 14 can also be, for example, a lens. The light emitting side of the light emitting part 12 faces the abutment part 19, and the first end of the first light guide part 13 is arranged on the abutment part 19. The light emitted by the light emitting part 12 is reflected, refracted, etc. by the first light guide part 13 and then emitted to the skin, thereby effectively expanding the irradiation range of the skin. The second end of the first light guide part 13 is spaced apart from the light emitting part 12. Such a design can provide movement space for the expansion and contraction of the abutment portion 19. Under the action of the elastic structure 18, the abutment portion 19 can expand and contract as the degree of fit between the abutment portion 19 and the user's skin to adjust the height of itself protruding from the main body 111. This can not only avoid the generation of gaps between the abutment portion 19 and the user's skin in certain usage scenarios, and avoid the accuracy of the physiological information detection device being reduced due to the tight fit between the abutment portion 19 and the user's skin, thereby effectively improving the accuracy of the monitoring results of the wearable device 1 and improving the user's usage experience, but also effectively improve the user's comfort when wearing the wearable device 1, thereby further improving the user's usage experience.

[0042] The light incident side of the light receiving part 14 faces the abutting part 19, and the light receiving part 14 is used to receive the light emitted and reflected by the light emitting part 12. The first end of the second light guiding part 15 is arranged on the abutting part 19, and the light emitted and reflected from the light emitting part 12 is gathered by the second light guiding part 15 to facilitate the reception by the light receiving part 14, so that more effective signals can be obtained, the effectiveness of the light is improved, and the accuracy of the monitoring results of the wearable device 1 is improved. The second end of the second light guiding part 15 is spaced apart from the light receiving part 14. Such a design also provides a moving space for the expansion and contraction of the abutting part 19, so that the abutting part 19 can expand and contract as the degree of fit between the abutting part 19 and the user's skin to adjust the height of itself protruding from the main body 111, thereby improving the accuracy of the monitoring results of the wearable device 1.

[0043] In one embodiment, the abutting portion 19 has a first limit position close to the physiological information detection device and a second limit position away from the physiological information detection device in the protruding direction of the abutting portion 19. In the first limit position, there is a first safety distance between the second end of the first light guide portion 13 and the light emitting portion 12, and the first safety distance can be, for example, 0.1mm to 0.2mm. In this way, it is avoided that the first light guide portion 13 and the light emitting portion 12 are affected by a collision during the expansion and contraction of the abutting portion 19, thereby affecting normal monitoring, thereby effectively improving the reliability of the wearable device 1. There is a second safety distance between the second end of the second light guide portion 15 and the light receiving portion 14, and the second safety distance can be, for example, 0.1mm to 0.2mm. In this way, it is avoided that the second light guide portion 15 and the light receiving portion 14 are affected by a collision during the expansion and contraction of the abutting portion 19, thereby affecting normal monitoring, thereby effectively improving the reliability of the wearable device 1.

[0044] Combine Figure 1 or Figure 2 In one embodiment, the light emitting part 12 and the light receiving part 14 are arranged on the first surface of the circuit board 16 in the housing 11 facing the abutment part 19. The wearable device 1 also includes a light shielding structure 17. The light shielding structure 17 can be arranged between the light emitting part 12 and the light receiving part 14, or the light shielding structure 17 can surround the light emitting part 12, or the light shielding structure 17 can surround the light receiving part 14. By providing the light shielding structure 17, it is avoided that the light emitted by the light emitting part 12 does not penetrate the skin and is directly received by the light receiving part 14, thereby causing a waste of this part of the light. The effectiveness of the light emitted by the light emitting part 12 is effectively improved, so that the light emitted by the light emitting part 12 can more effectively enter the skin tissue to collect effective signals, thereby further improving the accuracy of the monitoring results of the wearable device 1 and enhancing the user experience.

[0045] One end of the shading structure 17 is connected to the circuit board 16, and the other end of the shading structure 17 is connected to the abutment 19. Such a setting can not only effectively improve the stability of the shading structure 17 when it is fixed, but also improve the comprehensiveness of blocking the light emitted by the light emitting part 12, thereby further improving the effectiveness of the light emitted by the light emitting part 12. At least part of the structure of the shading structure 17 is flexible in the protruding direction of the abutment 19. For example, only part of the structure of the shading structure 17 can be flexible in the protruding direction of the abutment 19, or the entire structure of the shading structure 17 can be flexible in the protruding direction of the abutment 19. Such a design avoids the shading structure 17 from interfering with the expansion and contraction of the abutment 19, thereby further improving the accuracy of the monitoring results of the wearable device 1.

[0046] In one embodiment, the light shielding structure 17 is made of an elastic material. For example, the elastic material may be silicone. This allows the light shielding structure 17 to expand and contract with the contact portion 19, preventing interference from the light shielding structure 17 with the expansion and contraction of the contact portion 19, thereby further improving the accuracy of the monitoring results of the wearable device 1.

[0047] In another embodiment, combined with Figure 1 The light-shielding structure 17 includes a first light-shielding portion 171 and a second light-shielding portion 172. The first end of the first light-shielding portion 171 is connected to the circuit board 16, the first end of the second light-shielding portion 172 is connected to the second end of the first light-shielding portion 171, and the second end of the second light-shielding portion 172 is connected to the abutting portion 19. The first light-shielding portion 171 can be, for example, black instant noodles, and the second light-shielding portion 172 is an elastic material piece, and the elastic material can be, for example, silicone. The elasticity of the first light-shielding portion 171 in the protruding direction of the abutting portion 19 is less than the elasticity of the elastic material piece. By adopting such a setting, the first light-shielding portion 171 is prevented from being damaged due to excessive deformation, thereby affecting the light-shielding performance, thereby effectively ensuring the light-shielding effect.

[0048] In one embodiment, the distance between the second end of the first light shielding portion 171 and the circuit board 16 is greater than the distance between the second end of the first light guide portion 13 and the circuit board 16, and the distance between the second end of the first light shielding portion 171 and the circuit board 16 is greater than the distance between the second end of the second light guide portion 15 and the circuit board 16. It should be noted that, whether the abutting portion 19 is in the first or second extreme position, the distance between the second end of the first light guide portion 13 and the circuit board 16, as well as the distance between the second end of the second light guide portion 15 and the circuit board 16, is less than the distance between the second end of the first light shielding portion 171 and the circuit board 16. This design extends the length of the first light shielding portion 171, thereby providing better shielding for the light emitting portion 12 and / or the light receiving portion 14. Furthermore, because the elasticity of the first light shielding portion 171 in the protruding direction of the abutting portion 19 is less than that of the elastic material, the structural strength of the first light shielding portion 171 is enhanced, preventing damage to the first light shielding portion 171 due to excessive deformation, which could affect its light shielding performance, thereby further improving the light shielding effect.
