Description

Technical Field

[0001] This application relates to the technical field of testing equipment, specifically to a testing device, electronic equipment, and alerting method. Background Technology

[0002] In the field of vital information detection, common detection methods include using ultrasound to perform ultrasound imaging to obtain relevant vital information, such as ultrasound probes, which acquire image data from different planes and form a three-dimensional image by emitting and receiving ultrasound waves; another detection method is to use photoplethysmography (PPG) to obtain blood oxygen-related parameters, such as finger-clip pulse oximeters, which acquire blood oxygen-related parameters by emitting and receiving light; and yet another detection method is to use electrocardiography (ECG) to obtain cardiac-related parameters, such as an electrocardiogram (ECG) which extracts various forms of potential changes from the body surface by contacting electrodes with the skin.

[0003] Currently, most wearable devices and electronic devices such as smartwatches are equipped with health modules to obtain the aforementioned vital signs. However, balancing detection accuracy with the overall compactness of wearable / electronic devices has become a pressing technical challenge for cross-industry collaboration.

[0004] For example, finger-clip pulse oximeters typically test blood flow in the arteries on the fingertip. The skin on the fingertip is thinner, and the blood vessels are closer to the epidermis, allowing light to penetrate the skin and tissue more effectively for absorption and reflection by the blood, resulting in a higher quality signal. Finger-clip pulse oximeters rely on a spring structure to clamp the finger, providing a certain range of pressure and avoiding the force exerted by the finger on the test surface that often compresses the blood vessels and deforms their cross-section, thus affecting measurement accuracy.

[0005] However, when integrating the aforementioned functional detection modules into wearable / electronic devices, how to avoid excessive force on the test surface that could affect measurement accuracy has become a pressing technical problem. Summary of the Invention

[0027] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be particularly noted that the following embodiments are for illustrative purposes only and do not limit the scope of the application. Similarly, the following embodiments are only some, not all, embodiments of the present application, and all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of the present application.

[0028] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0029] As described in the background section, conventional fingertip pulse oximeters, ultrasound detection devices, and electrocardiogram (ECG) detection devices are difficult to integrate into wearable / electronic devices. Therefore, embodiments of this application provide a detection device that can be integrated into wearable / electronic devices while meeting relevant detection requirements, thus balancing the compactness of the wearable / electronic device's structure with the detection needs.

[0030] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the structure of the detection device 10 in some embodiments of this application. Figure 2 yes Figure 1 A schematic diagram of the cross-sectional structure of the detection device 10 in the embodiment.

[0031] The detection device 10 may include a detection component 100 and a housing component 200 capable of relative movement. The detection component 100 may be configured to use ultrasound to perform ultrasound imaging to obtain relevant vital signs, or it may be configured to use PPG to obtain blood oxygenation parameters, or it may be configured to use ECG to obtain an electrocardiogram, etc. The housing component 200 is configured to assemble the detection component 100 and to position the detection component 100. The housing component 200 may be a plate-like structure, a frame structure, or a box-like structure, etc.

[0032] Furthermore, the detection component 100 and the housing component 200 can move relative to each other, allowing the detection component 100 to have a certain travel distance. This enables the detection component 100 to sense the contact between itself and the surface of the object under test, as well as the stress on the surface of the object under test. Under the action of an external force, the detection component 100 can move relative to the housing component 200 to a first position. At this position, the user can sense that the detection component 100 is in good contact with the surface of the object under test, but the surface of the object under test may undergo excessive deformation due to excessive stress. Furthermore, when the external force is removed, the detection component 100 can move relative to the housing component 200 to a second position, i.e., reset.

[0033] Specifically, the detection component 100 has a detection surface 101 for receiving the aforementioned external force. When the detection surface 101 contacts the surface of the object under test, the object under test can apply a force to the detection surface 101, causing the detection component 100 to move relative to the housing assembly 200 to a first position. At this position, the user can perceive good contact between the detection component 100 and the surface of the object under test. However, when the detection component 100 is in the first position, the surface of the object under test may undergo excessive deformation due to excessive force. When the object under test removes the force applied to the detection surface 101, the detection component 100 moves relative to the housing assembly 200 to a second position, i.e., returns to the initial position.

[0034] When the detection surface 101 is in contact with the surface of the individual being tested, and the force applied to the detection surface 101 is excessive, the area to be tested may be forced into excessive deformation, thus affecting the accuracy of the measurement. Insufficient contact between the detection surface 101 and the surface of the individual being tested may also affect the accuracy of the measurement results. Taking the detection component 100 configured to use PPG to acquire blood oxygen-related parameters as an example, its detection surface 101 can contact the surface of the fingertip of the individual being tested. This is because the blood vessels at the fingertip are closer to the epidermis, allowing light to penetrate the skin and tissue better to reach the blood and be reflected, resulting in a higher quality reflected signal. When the force applied by the fingertip to the detection surface 101 is excessive, it may cause the blood vessels at the fingertip to be forced into excessive deformation, thus affecting blood flow velocity or even causing poor blood flow, ultimately affecting the accuracy of the measurement. When the contact between the detection surface 101 and the surface of the fingertip is insufficient, the light propagation efficiency may be affected, thus affecting the accuracy of the measurement. Of course, in other embodiments, the detection surface 101 may also contact other surfaces of the individual being tested.

[0035] Understandably, when the detection component 100 is configured to use ultrasound to perform ultrasound imaging to obtain relevant vital information, excessive force applied to the detection surface 101 may cause excessive deformation of the measured area, affecting the accuracy of ultrasound detection; insufficient contact between the detection surface 101 and the measured surface may affect the ultrasound propagation efficiency, thus affecting measurement accuracy. When the detection component 100 is configured to use ECG to obtain an electrocardiogram, excessive force applied to the detection surface 101 may cause changes in electrode contact resistance, affecting detection accuracy; insufficient contact between the detection surface 101 and the measured surface may cause defects such as poor electrode contact, affecting measurement accuracy.

[0036] Based on this, this application provides a detection component 100 and a housing component 200 that are capable of relative movement. When the detection surface 101 contacts the surface of the object under test and receives the force applied by the object, the detection component 100 can move to a first position; when the force applied to the detection surface 101 is removed, i.e., when the detection surface 101 separates from the surface of the object under test, the detection component 100 can move to a second position. That is, the detection component 100 moves relative to the housing component 200 so that the user can perceive the force on the surface of the object under test, thereby avoiding excessive force on the surface of the object under test.

[0037] In one embodiment, the housing assembly 200 may have a slot 201. The detection assembly 100 may be disposed in the slot 201 and have a portion protruding from the slot 201, and the detection surface 101 of the detection assembly 100 is formed on the portion of the detection assembly 100 protruding from the slot 201.

[0038] The detection component 100 is movable relative to the housing assembly 200 in the axial direction of the slot 201, allowing the detection component 100 to switch between a first position and a second position. The detection surface 101 of the detection component 100 can be exposed from the opening of the slot 201 to receive external forces.

[0039] Optionally, the slot 201 can be a through hole penetrating the housing assembly 200, or the slot 201 can be a blind hole communicating with one side of the housing assembly 200. The peripheral side of the detection assembly 100 can be slidably connected to the inner wall of the slot 201. For example, one of the peripheral side of the detection assembly 100 and the inner wall of the slot 201 is provided with a slide rail, and the other is provided with a slider. The slider cooperates with the slide rail to guide the detection assembly 100 to move relative to the housing assembly 200 in the axial direction of the slot 201.

[0040] In one embodiment, one of the detection component 100 and the housing component 200 is provided with a mating position 102, and the other is provided with a mating member 202 corresponding to the mating position 102. The detection component 100 can move relative to the housing component 200 to a first position under the action of an external force. In the first position, the mating member 202 engages with the mating position 102, and a restoring force is generated between the detection component 100 and the housing component 200. When the external force is removed, the detection component 100 can move to a second position under the action of the restoring force. In the second position, the mating member 202 separates from the mating position 102. In some embodiments, such as Figure 2 As shown, the mating member 202 can be a snap-fit ​​member, and the mating position 102 can be a snap-fit ​​groove. In other embodiments, the mating position may not be a groove, but a plane or a protrusion, and the mating member may also be a plane or a protrusion. In some embodiments, one of the mating member and the mating position can be a conductive member, and the other can be an insulating part; or, both the mating member and the mating position can be conductive members. Taking the snap-fit ​​member and the snap-fit ​​groove as an example, in the first position, the snap-fit ​​member can move in the direction intersecting the movement of the detection component 100 so that the snap-fit ​​member at least partially enters the snap-fit ​​groove to limit the movement stroke of the detection component 100. In the second position, the snap-fit ​​member separates from the snap-fit ​​groove. Wherein, when the snap-fit ​​member is disposed on the detection component 100, the snap-fit ​​member can abut against the housing component 200 in the second position; when the snap-fit ​​member is disposed on the housing component 200, the snap-fit ​​member can abut against the detection component 100 in the second position, thereby achieving the positioning of the detection component 100.

[0041] It should be noted that, in the embodiments of this application, the engaging parts and engaging slots can be replaced with other forms of engaging parts and engaging positions, unless otherwise specified.

[0042] In some embodiments, one of the mating member and the mating position may be disposed on the outer sidewall of the detection assembly 100 or on the inner sidewall of the space in the housing assembly 200 for supporting the detection assembly 100, thereby achieving mating or disengagement as the detection assembly 100 and the housing assembly 200 move relative to each other. (See also...) Figure 3 , Figure 3 yes Figure 1 Another cross-sectional structural diagram of the detection device 10 in the embodiment. Figure 2 The diagram shows the structure of the detection component 100 in the second position. Figure 3 The diagram illustrates the structure of the detection component 100 in its first position. Figure 2 and Figure 2 The mating part 202 is a snap-fit ​​part, and the mating position 102 is a snap-fit ​​groove.

[0043] in, Figure 2 and Figure 3 The illustration shows an embodiment where the mating position 102 is provided on the detection component 100 and the mating part 202 is provided on the housing component 200, but it is not limited thereto.

[0044] When the detection surface 101 is subjected to an external force, causing the detection component 100 to move until the mating part 202 at least partially enters the mating position 102, the user can clearly perceive a sudden change in resistance. This is intended to remind the user that the force on the detection component 100 may be too great, causing excessive deformation of the surface of the object being tested, and thus reminding the user to reduce the force applied to the detection surface 101. When the external force is removed, the detection component 100 moves until the mating part 202 separates from the mating position 102 to reset to the test state, at which point the mating part 202 can abut against the detection component 100.

[0045] In other words, when the detection component 100 is in the test state, i.e., the second position, the mating part 202 can abut against the detection component 100 to position it. When the detection surface 101 receives an external force that causes the detection component 100 to move, the external force overcomes the resistance of the mating part 202 against the detection component 100, causing the detection component 100 to move. When the detection component 100 moves to the point where the mating part 202 is opposite to the mating position 102, the resistance of the mating part 202 against the detection component 100 disappears, and the user can clearly perceive a sudden change in resistance. At this time, it is necessary to reduce the external force on the detection surface 101 to return the detection component 100 from the first position to the second position to avoid excessive deformation of the surface of the object being tested. When the detection component 100 is in the first position, the mating part 202 enters the mating position 102.

[0046] Optionally, the mating member 202 can be a POGO PIN structure, which allows for elastic extension and retraction. When the detection component 100 is in the second position, the mating member 202 abuts against the detection component 100; when the detection component 100 is in the first position, one end of the mating member 202 enters the mating position 102. Of course, in other embodiments, the mating member 202 can be a retractable structure similar to a POGO PIN. In other words, the engaging member can be a telescopic structure; when the engaging member extends and engages with the engaging slot, the detection device 10 triggers a reminder to prompt the user to reduce the external force applied to the detection surface 101.

[0047] Optionally, the mating part 202 can be a locking block embedded in the inner wall of the slot 201 by means of an elastic element such as a spring or foam. When the detection component 100 is in the second position, the mating part 202 is retracted into the inner wall of the slot 201 and can abut against the detection component 100; when the detection component 100 is in the first position, the mating part 202 enters the mating position 102 under the elastic force of the spring or foam.

[0048] Understandably, at least one of the mating part 202 and the mating position 102 may be provided with a guide ramp, which is configured to guide the mating part 202 into the mating position 102, or to guide the mating part 202 out of the mating position 102.

[0049] In one embodiment, the detection component 100 is provided with a first magnetic element 103, and the housing component 200 is provided with a second magnetic element 203. A magnetic force exists between the first magnetic element 103 and the second magnetic element 203. When the detection surface 101 is subjected to an external force, the detection component 100 moves relative to the housing component 200 against the magnetic force between the first magnetic element 103 and the second magnetic element 203. When the external force on the detection surface 101 is removed, the detection component 100 moves relative to the housing component 200 under the action of the magnetic force between the first magnetic element 103 and the second magnetic element 203. The magnetic force of the first magnetic element 103 and the second magnetic element 203 can be either a magnetic repulsion force or a magnetic attraction force, and their positions can be flexibly set according to the nature of the magnetic force between them. The first magnetic element 103 and the second magnetic element 203 can be magnetic bodies such as magnets.

[0050] like Figure 2 and Figure 3As shown, when there is a magnetic repulsion between the first magnetic element 103 and the second magnetic element 203, the first magnetic element 103 and the second magnetic element 203 can be located at the end of the stroke of the detection component 100 from the second position to the first position. In some embodiments, the first magnetic element 103 and the second magnetic element 203 are arranged opposite to each other, and the first magnetic element 103 can be located at the end of the detection component 100 away from the detection surface 101, and a magnetic repulsion can be generated between the first magnetic element 103 and the second magnetic element 203.

[0051] Of course, in other embodiments, when there is a magnetic attraction between the first magnetic element 103 and the second magnetic element 203, the first magnetic element 103 and the second magnetic element 203 can be located at the end of the stroke of the detection component 100 from the first position to the second position. In some embodiments, the first magnetic element 103 can be provided on the detection component 100, and the second magnetic element 203 can be provided on the housing component 200. The first magnetic element 103 can be located at the bottom of the detection component 100, and the second magnetic element 203 can be located in the housing component 200 at a position higher than the first magnetic element 103, thereby magnetically attracting the first magnetic element 103. Furthermore, in other embodiments, the first magnetic element 103 and the second magnetic element 203 can be arranged opposite to each other, and the first magnetic element 103 can be provided on the side of the detection component 100 adjacent to the detection surface 101, and the second magnetic element 203 can be provided on the inner sidewall of the slot 201 of the housing component 200.

[0052] Please see Figure 4 , Figure 4 This is a cross-sectional structural diagram of the detection device 10 in some other embodiments of this application. The detection device 10 may include a first elastic member 300 disposed between the detection component 100 and the housing component 200. When the detection surface 101 is subjected to an external force, the detection component 100 may move relative to the housing component 200, so that the first elastic member 300 deforms and generates elastic force. When the external force on the detection surface 101 is removed, the detection component 100 moves relative to the housing component 200 under the elastic force of the first elastic member 300. The elastic force generated by the deformation of the first elastic member 300 may be an elastic force generated by stretching or an elastic force generated by compression. The position of the first elastic member 300 can be flexibly set according to the deformation mode of the first elastic member 300. The first elastic member 300 may be a structure capable of elastic deformation, such as a spring, foam, or rubber.

[0053] like Figure 4 As shown, when the first elastic element 300 is compressed to generate elastic force, the first elastic element 300 can be located at the end of the stroke of the detection component 100 moving from the second position to the first position.

[0054] Of course, in other embodiments, when the first elastic element 300 is stretched, the first elastic element 300 may be located at the end of the stroke of the detection component 100 as it moves from the first position to the second position.

[0055] In summary, when the detection component 100 is in the second position, i.e., in the test state, the detection component 100 is approximately suspended in the slot 201 of the housing component 200. That is, the detection component 100 can be suspended in the slot 201 by the mating member 202 contacting the detection component 100, and / or by the magnetic force between the first magnetic member 103 and the second magnetic member 203, and / or by the first elastic member 300 supporting the detection component 100. When the surface of the individual to be tested comes into contact with the detection surface 101 and a force is applied to the detection surface 101, causing the detection component 100 to move to the first position, the mating part 202 engages with the mating position 102. In some embodiments, the individual can perceive a sudden change in resistance; for example, after the engaging part engages with the engaging groove, the resistance decreases, allowing the user to adjust the force. In some embodiments, when the mating part 202 and the mating position 102 are engaged, the user can be alerted via voice, image, or other means, so that the user is aware that the force on the detection surface 101 of the individual to be tested is too great and needs to be reduced so that the detection component 100 can return from the first position to the second position for parameter detection. This can prevent excessive deformation of the individual's test area from affecting the accuracy of the test results. In some embodiments, the above two alerts can coexist.

[0056] After the test is completed, the surface of the individual being tested separates from the detection surface 101. At this time, the detection component 100 needs to return to its initial position, i.e., the second position. In some embodiments, when the surface of the individual being tested separates from the detection surface 101, the detection component 100 can be manually (e.g., by shaking) reset to the second position. In some embodiments, when the detection component 100 is in the first position, a restoring force can be generated between the detection component 100 and the housing component 200. This restoring force can be used to move the detection component 100 to the second position, i.e., reset. The restoring force can be the aforementioned magnetic force or elastic force. Of course, in some embodiments, the restoring force can be the force exerted on the detection component 100 by a driving mechanism, such as a motor drive mechanism or a turbine drive mechanism.

[0057] The detection device provided in this application embodiment, by setting up a detection component and a housing component capable of relative movement, allows the detection component to move to a first position when the detection surface contacts the surface of the individual being tested and receives the force applied by the individual. At this point, the mating parts and mating positions can engage, indicating that the force applied to the detection surface of the individual being tested is too large and needs to be reduced, thereby avoiding excessive deformation of the tested area and affecting the accuracy of the detection results. When the force applied to the detection surface is removed, i.e., when the detection surface separates from the surface of the individual being tested, the detection component can move to a second position to return to the initial state. In other words, by setting the detection component to move relative to the housing component so that the individual being tested can know the force situation of the detection surface, excessive force on the surface of the individual being tested and excessive deformation can be avoided, thereby ensuring the accuracy of the detection results.

[0058] In one embodiment, such as Figures 2 to 4 As shown, the housing assembly 200 may include a first housing 210 and a second housing 220, which can cooperate to form a receiving cavity 204. The first housing 210 has a through hole 205 communicating with the receiving cavity 204. The detection assembly 100 is movable relative to the housing assembly 200 in the axial direction of the through hole 205. A slot 201 may be formed in the receiving cavity 204, with the through hole 205 serving as the opening of the slot 201.

[0059] Optionally, the receiving cavity 204 can be used to receive other structural components of the detection device 10, such as circuit boards and sensor components, in addition to accommodating part of the detection assembly 100.

[0060] Furthermore, a portion of the detection component 100 is disposed in the receiving cavity 204, and another portion passes through the through hole 205. That is, the detection component 100 has a first portion disposed in the receiving cavity 204 and a second portion passing through the through hole 205. The detection surface 101 is formed on the surface of the second portion facing away from the first portion. A first elastic member 300 is disposed between the first portion and the second housing 220. When the restoring force that causes the detection component 100 to move to the second position is a magnetic force, one of the first magnetic member 103 and the second magnetic member 203 is disposed on the portion of the detection component 100 disposed in the receiving cavity 204 (i.e., the first portion), and the other is disposed on the second housing 220. When the restoring force that causes the detection component 100 to move to the second position is an elastic force, the first elastic member 300 is disposed between the detection component 100 and the second housing 220. That is, one end of the first elastic member 300 abuts against the portion of the detection component 100 disposed in the receiving cavity 204 (i.e., the first portion), and the other end abuts against the second housing 220.

[0061] Please see Figure 5 and Figure 6 , Figure 5This is a structurally exploded schematic diagram of the detection device 10 in some embodiments of this application. Figure 6 yes Figure 5 Another structural breakdown diagram of the detection device 10 in the embodiment.

[0062] The housing assembly 100 may include a first housing 210 and a second housing 220 disposed on one side of the first housing 210. One side of the first housing 210 may be an open structure, and the second housing 220 covers the open side of the first housing 210, thereby together with the first housing 210 enclosing the receiving cavity 204 of the detection device 10. Alternatively, in other embodiments, one side of the second housing 220 may be an open structure, and the first housing 210 covers the open side of the second housing 220, thereby together with the second housing 220 enclosing the receiving cavity 204 of the detection device 10. Furthermore, in some embodiments, one side of the first housing 210 may be an open structure, and one side of the second housing 220 may be an open structure, with the first housing 210 covering the open side of the second housing 220, thereby together with the second housing 220 enclosing the receiving cavity 204 of the detection device 10.

[0063] The first housing 210 and the second housing 220 can be assembled and connected by means of screwing, bonding, welding, snap-fitting, or detachment. The first housing 210 is provided with a through hole 205, which penetrates the first housing 210 and connects to the receiving cavity 204.

[0064] Optionally, the first housing 210 and the second housing 220 can be integrally formed by processes such as injection molding, stamping, or hot-dip molding. Alternatively, the first housing 210 and the second housing 220 can also be two independent structural components, which can be connected by one or a combination of assembly methods such as screwing, bonding, welding, snap-fitting, or detachable assembly.

[0065] Furthermore, the housing assembly 100 can be made of materials such as glass, metal, and hard plastic, giving it a certain structural strength. Since the housing assembly 100 is generally directly exposed to the external environment, it can also possess properties such as wear resistance, corrosion resistance, and scratch resistance, or a layer of wear-resistant, corrosion-resistant, and scratch-resistant functional material can be coated on the outer surface of the housing assembly 100 (i.e., the outer surface of the detection device 10). In some embodiments, a corresponding brand logo can also be provided on the housing assembly 100 to enhance the appearance of the detection device 10 and improve brand recognition.

[0066] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of this application are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0067] The detection component 100 may include a bracket 110, a transmitter 120, and a receiver 130.

[0068] The bracket 110 is slidably connected to the first housing 210 so that the detection component 100 can move relative to the housing assembly 200. The bracket 110 has an end that passes through the through hole 205, and a detection surface 101 is formed on the end of the bracket 110 that passes through the through hole. In other words, the bracket 110 has a surface exposed from the through hole 205 onto the surface of the housing assembly 200, and the detection surface 101 is formed on the surface of the bracket 110 exposed from the through hole 205 onto the surface of the housing assembly 200.

[0069] The signal emitted by the transmitter 120 can be emitted through the through-hole 205 to reach the object under test. The receiver 130 receives the signal reflected by the external object, i.e., the object under test, through the through-hole 205. The transmitter 120 can be a light emitter or an ultrasonic emitter, such as a light-emitting diode (LED). The receiver 130 can be a light receiver or an ultrasonic receiver, such as a photodiode.

[0070] Optionally, one of the bracket 110 and the first housing 210 is provided with a slider and the other is provided with a slide rail. The slider and the slide rail cooperate to realize the sliding connection between the bracket 110 and the first housing 210.

[0071] In one embodiment, the bracket 110 may include a first bracket 111 and a second bracket 112, with the first bracket 111 slidably connected to the first housing 210. The second bracket 112 is disposed between the first bracket 111 and the first housing 210 and connected to the first bracket 111. The detection surface 101 of the detection component 100 is formed on the end face of the second bracket 112 facing away from the first bracket 111. Further, the first bracket 111 is disposed within the receiving cavity 204, and the second bracket 112 passes through the through hole 205. Of course, in other embodiments, the second bracket 112 may be slidably connected to the first housing 210 and connected to the first bracket 111. That is, the detection component 100 can move relative to the housing assembly 200 through the slidable connection between the first bracket 111 or the second bracket 112 and the first housing 210.

[0072] See also Figure 7 , Figure 7 yes Figure 6In the cross-sectional structural diagram of the detection device 10 in the embodiment, one of the first housing 210 and the first support 111 may be provided with a guide post 211, and the other may be provided with a guide hole 212. The guide post 211 can move axially along the guide hole 212 to achieve a sliding connection between the first support 111 and the first housing 210. Further, the guide post 211 is located on the side of the first housing 210 near the second housing 220, and the guide hole 212 is located on the first support 111. The guide post 211 can be inserted into or pass through the guide hole 212 and can move axially in the guide hole 212.

[0073] Optionally, multiple guide posts 211 may be provided, and the multiple guide posts 211 are distributed around the outer periphery of the through hole 205. Preferably, the multiple guide posts 211 are evenly distributed around the outer periphery of the through hole 205. Multiple guide holes 212 may be provided, and each guide hole 211 is corresponding to one guide post 211. Preferably, the multiple guide holes 212 are evenly distributed on the first bracket 111. It is understood that the outer periphery of the first bracket 111 may be provided with a lug, and the guide hole 212 is provided on the lug. Of course, in other embodiments, the guide posts 211 may be provided on the first bracket 111, and the guide holes 212 may be provided on the first housing 210; please refer to the above embodiments for details.

[0074] The detection assembly 10 may also include a limiting member 140, which is connected to the guide post 211 and can move with the guide post 211 to limit the travel of the guide post 211.

[0075] When the guide post 211 is disposed on the first bracket 111 and the guide hole 212 is disposed on the first housing 210, one end of the guide post 211 passes through the guide hole 212, and the limiting member 140 is connected to the end of the guide post 212 that passes through the guide hole 212. When the detection assembly 100 is in the first position, the limiting member 140 abuts against the first housing 210; when the detection assembly 100 is in the second position, the limiting member 140 is spaced apart from the first housing 210.

[0076] When the guide post 211 is disposed on the first housing 210 and the guide hole 212 is disposed on the first bracket 111, one end of the guide post 211 passes through the guide hole 212, and the limiting member 140 is connected to the end of the guide post 212 that passes through the guide hole 212. When the detection assembly 100 is in the first position, the limiting member 140 is spaced apart from the first housing 210; when the detection assembly 100 is in the second position, the limiting member 140 abuts against the first housing 210.

[0077] Optionally, the limiting member 140 and the guide post 211 enter the guide hole 212 from opposite ends, respectively, and the end of the limiting member 140 entering the guide hole 212 is connected to the end of the guide post 211 entering the guide hole 212. The end of the limiting member 140 outside the guide hole 212 can limit the travel of the guide post 211 when the detection assembly 100 moves.

[0078] For example, the limiting member 140 can be a screw or bolt, and the guide post 211 can be provided with a screw hole. The limiting member 140 is inserted into the screw hole of the guide post 211 and connected to the guide post 211. The nut or flange protrusion of the limiting member 140 can limit the movement stroke of the guide post 211 to prevent the guide post 211 from disengaging from the guide hole 212.

[0079] The travel distance of the guide post 211 relative to the guide hole 212 is approximately the same as the deformation travel distance of the first elastic element 300. This further prevents excessive force and deformation of the test area of ​​the individual being measured, thus ensuring measurement accuracy. In other words, the travel distance of the detection component 100 relative to the first housing 210 is consistent with the deformation travel distance of the first elastic element 300.

[0080] In one embodiment, the detection component 10 may further include a first circuit board 150, which is disposed on the side of the first bracket 111 opposite to the second bracket 112. The transmitter 120 and the receiver 130 are electrically connected to the first circuit board 150 to realize signal transmission and reception.

[0081] Optionally, the detection component 10 may further include a fastener 160, which may be sequentially inserted through the first circuit board 150 and the first bracket 111, and connected to the second bracket 112. The fastener 160 may be a screw or a bolt. Preferably, the second bracket 112 has a connecting post 213 on the side near the first bracket 111, and the first bracket 111 has a connecting hole 214. The fastener 160 and the connecting post 213 enter the connecting hole 214 from opposite ends, and the end of the fastener 160 entering the connecting hole 214 is connected to the end of the connecting post 213 entering the connecting hole 214.

[0082] Understandably, using fasteners 160 to fix the first circuit board 150, the first bracket 111, and the second bracket 112 together makes the overall structure of the detection assembly 100 more compact. Multiple fasteners 160, connecting posts 213, and connecting holes 214 can be provided, and each can be configured in a corresponding manner.

[0083] Of course, in other embodiments, adjacent pairs of the first circuit board 150, the first bracket 111 and the second bracket 112 can be assembled and connected by means of screwing, bonding, welding, snap-fitting or detachable connection.

[0084] Optionally, the transmitter 120 and receiver 130 can be respectively disposed on the first circuit board 150. That is, the transmitter 120 and receiver 130 can be disposed on the side of the first circuit board 150 near the first bracket 111 by means of surface mounting or soldering, so as to achieve electrical connection with the first circuit board 150 respectively. The first bracket 111 is disposed between the first circuit board 150 and the second bracket 120. The first bracket 111 can be disposed on the first circuit board 150 and surround the transmitter 120 and receiver 130, that is, the transmitter 120 and receiver 130 are assembled within the space formed by the first bracket 111. The second bracket 112 is disposed on the side of the first bracket 111 away from the first circuit board 150 and passes through the through hole 205 to form a detection surface 101 on the end face of the second bracket 112 away from the first bracket 111. The second bracket 112 can be sleeved on the first bracket 111 and abut against the first circuit board 150, so as to make the structure of the detection assembly 100 more compact.

[0085] As mentioned above, the first support 111 can be a ring-shaped structure, and a partition wall 1110 can be provided within the space it encloses. This partition wall 1110 is located between the transmitter 120 and the receiver 130 to prevent the signal emitted by the transmitter 120 from directly reaching the receiver 130 and affecting the accuracy of the detection. That is, the partition wall 1110 divides the space enclosed by the first support 111 into two spaced spaces, which are respectively used to assemble the transmitter 120 and the receiver 130 to improve the accuracy of the detection.

[0086] Please see Figures 8 to 10 , Figure 8 This is a structural breakdown diagram of the detection component 100 in some other embodiments of this application. Figure 9 yes Figure 8 A schematic diagram of the structure of the first support 111 in the embodiment. Figure 10 yes Figure 8 A schematic diagram of the structure of the second bracket 112 in the embodiment. In this embodiment, the transmitter 120 is a light transmitter and the receiver 130 is a light receiver.

[0087] Understandably, the light emitter can be a device capable of emitting detection light, such as red or green light, and is electrically connected to the first circuit board 150 to emit detection light under the control of the first circuit board 150. The light receiver can be a photoelectric sensor capable of converting the received light signal into an electrical signal and transmitting it through the first circuit board 150. In the actual detection process, the light emitter emits detection light under the control of the first circuit board 150 and shines it into the human body. Part of the light is absorbed by the human body, and the other part is reflected and received by the light receiver. The detection device 10 calculates the detection light signal received by the light receiver and the detection light signal emitted by the light emitter by comparing and calculating the human health data.

[0088] The detection assembly 10 may further include a lens 170 disposed between the first support 111 and the second support 112. The detection light emitted by the transmitter 120 can exit the detection device 10 through the lens 170, and the detection light reflected back from the individual under test can be received by the receiver 130 after passing through the lens 170. The lens 170 is spaced apart from the first circuit board 150, and the light transmitter and light receiver are disposed between the first circuit board 150 and the lens 170, and respectively mounted on the first circuit board 150.

[0089] Optionally, the projection of the lens 170 onto the first housing 210 may cover the through hole 205, and the projection of the first circuit board 150 onto the first housing 210 may cover the through hole 205. Of course, in other embodiments, the projection of the lens 170 onto the first housing 210 may not extend beyond the outer edge of the through hole 205.

[0090] Furthermore, the lens 170 may include a first light-transmitting portion and a second light-transmitting portion spaced apart. The first light-transmitting portion is disposed opposite to the transmitter 120 and can be used to converge the detection light emitted by the transmitter 120 so that the detection light shines outside the detection device 10. The second light-transmitting portion is disposed opposite to the receiver 130 and can be used to converge the detection light reflected back by the individual to be tested so that the receiver 130 can receive the detection light carrying information about the user's body tissue.

[0091] Lens 170 can be a light-gathering lens or a Fresnel lens. Optionally, lens 170 can also be made of a transparent material such as glass, polyimide, colorless polyimide, or polyethylene terephthalate, and have Fresnel patterns on one side.

[0092] See also Figure 11 , Figure 11 yes Figure 8A schematic cross-sectional view of the detection component 100 in this embodiment. The lens 170 may include a first lens 171 disposed opposite to the transmitter 120 and a second lens 172 disposed opposite to the receiver 130. The detection light emitted by the transmitter 120 can be emitted through the first lens 171, and the detection light reflected back by the individual being tested can be received by the receiver 130 through the second lens 172. It is understood that the number of the first lens 171 and / or the second lens 172 can vary accordingly as the number of transmitters 120 and / or receivers 130 changes; this embodiment does not specifically limit this. The first lens 171 may be the aforementioned first light-transmitting portion, and the second lens 172 may be the aforementioned second light-transmitting portion.

[0093] As mentioned above, the first support 111 may be annular and surround the periphery of the transmitter 120 and the receiver 130. The first support 111 has a first groove 1111 and a second groove 1112 located on opposite sides of the partition wall 1110. A first lens 171 covers the opening of the first groove 1111, and a second lens 172 covers the opening of the second groove 1112. The first lens 171 and the second lens 172 are spaced apart by the partition wall 1110, that is, the partition wall 1110 is located between the first lens 171 and the second lens 172 to prevent light from crossing between the first lens 171 and the second lens 172.

[0094] Optionally, the first groove 1111 can serve as a carrier for the first lens 171, and can be fixedly connected to the first lens 171 by means of screwing, bonding, welding, or snap-fitting. The second groove 1112 can serve as a carrier for the second lens 172, and can be fixedly connected to the second lens 172 by means of screwing, bonding, welding, or snap-fitting. Optionally, the first lens 171 can be embedded in the first groove 1111, and the second lens 172 can be embedded in the second groove 1112, so that the overall structure of the detection assembly 100 is more compact.

[0095] Optionally, the surface of the first lens 171 facing away from the first circuit board 150 may not protrude beyond the surface of the first support 111 facing away from the first circuit board 150. Similarly, the surface of the second lens 172 facing away from the first circuit board 150 may not protrude beyond the surface of the first support 111 facing away from the first circuit board 150. Preferably, the surface of the first lens 171 facing away from the first circuit board 150 may be flush with the surface of the first support 111 facing away from the first circuit board 150. The surface of the second lens 172 facing away from the first circuit board 150 may also be flush with the surface of the first support 111 facing away from the first circuit board 150.

[0096] like Figure 9As shown, the first groove 1111 and the second groove 1112 are located on the inner side of the first bracket 111. The outer side of the first bracket 111 may also be provided with a protrusion 1113. The guide hole 212 and the connecting hole 214 pass through the protrusion 1113 and are spaced apart.

[0097] Of course, in other embodiments, the lens 170 can be an integral structure with a groove corresponding to the partition wall 1110. When the lens 170 is placed on the first bracket 111, the partition wall 1110 is inserted into the groove on the lens 170 to position the lens 170. At this time, the parts of the lens 170 located on both sides of the groove can be respectively embedded in the first groove 1111 and the second groove 1112.

[0098] In one embodiment, the detection assembly 100 may further include a transparent cover plate 180 disposed on the second bracket 112, which is exposed to the outside of the detection device 10 through the through hole 205. The detection surface 101 of the detection assembly 100 is formed on the surface of the transparent cover plate 180 facing away from the lens 170. Specifically, the second bracket 112 has a mounting hole 1120, which can be a circular hole or a rectangular hole, etc., without specific limitation.

[0099] Furthermore, the projection of the transparent cover plate 180 onto the second bracket 112 covers the mounting hole 1120. The transparent cover plate 180 can be embedded within the mounting hole 1120 to ensure the sealing of the detection device 10; alternatively, the transparent cover plate 180 can be located on the side of the second bracket 112 facing away from the first bracket 111, and can cover the mounting hole 1120. Optionally, the transparent cover plate 180 can be located on the side of the second bracket 112 closer to the first bracket 111, and can cover the mounting hole 1120. It is understood that the detection light emitted by the transmitter 120 is emitted sequentially through the lens 170 and the transparent cover plate 180, and the detection light reflected back from the object under test can be received by the receiver 130 sequentially through the transparent cover plate 180 and the lens 170. The transparent cover plate 180 can be made of a transparent material such as glass or sapphire.

[0100] Optionally, the transparent cover 180 and the second bracket 112 can be assembled as two independent components, or they can be integrally formed through a corresponding process, i.e., the transparent cover 180 and the second bracket 112 can be a single structure. Optionally, the mounting hole 1120 and the through hole 205 are coaxial.

[0101] In one embodiment, the transparent cover plate 180 may be provided with a first light-transmitting area 181 and a second light-transmitting area 182. The first light-transmitting area 181 is disposed opposite to the first lens 171, and the second light-transmitting area 182 is disposed opposite to the second lens 172. The detection light emitted by the transmitter 120 is emitted sequentially through the first lens 171 and the first light-transmitting area 181, and the detection light reflected back from the individual under test can be received by the receiver 130 sequentially through the second light-transmitting area 182 and the second lens 172. The first light-transmitting area 181 and the second light-transmitting area 182 can be areas formed by performing a light-blocking treatment on the surface of the transparent cover plate 180. For example, ink can be sprayed or black screen printed on the surface of the transparent cover plate 180, and the areas without ink spraying or black screen printing are the first light-transmitting area 181 and the second light-transmitting area 182.

[0102] like Figure 11 As shown, the mounting hole 1120 has a communicating first hole section 1121 and a second hole section 1122. Optionally, the first hole section 1121 and the second hole section 1122 are coaxially arranged. The inner diameter of the first hole section 1121 is smaller than the inner diameter of the second hole section 1122, forming a stepped structure at the junction of the first hole section 1121 and the second hole section 1122. The outer periphery of the transparent cover plate 180 abuts against the junction of the first hole section 1121 and the second hole section 1122 to position the transparent cover plate 180.

[0103] like Figure 10 As shown, the second bracket 112 is fitted onto the first bracket 111. In this case, the engaging groove 102 can be located on the outer peripheral side of the second bracket 112. Of course, in other embodiments, when the first bracket 111 is fitted onto the second bracket 112, the engaging groove 102 can be located on the outer peripheral side of the first bracket 111. Furthermore, when the outer peripheral edge of the first circuit board 150 protrudes beyond the first bracket 111 and the second bracket 112, the engaging groove 102 can also be located on the outer peripheral side of the first circuit board 150.

[0104] In one embodiment, the detection assembly 100 may further include a spacer 190 disposed between the lens 170 and the transparent cover plate 180. The opposite sides of the spacer 190 abut against the lens 170 and the transparent cover plate 180 respectively to prevent direct contact and impact damage between the lens 170 and the transparent cover plate 180 during assembly. The spacer 190 may be a cushioning material such as foam, rubber, or silicone.

[0105] Optionally, the isolator 190 has a cutout to prevent signal propagation, so that the signal from the transmitter 120 can be emitted smoothly and the signal from the receiver 130 can be received smoothly.

[0106] like Figure 8As shown, the isolation member 190 has a first hollow portion 191 and a second hollow portion 192 that are spaced apart. The first hollow portion 191 is disposed between the first lens 171 and the first light-transmitting area 181, and the second hollow portion 192 is disposed between the second lens 172 and the second light-transmitting area 182.

[0107] In other words, the first hollow portion 191 is disposed opposite to the first light-transmitting portion of the lens 170, and the second hollow portion 192 is disposed opposite to the second light-transmitting portion of the lens.

[0108] Furthermore, in the actual assembly process, the assembly of the first bracket 111 and the lens 170, the assembly of the second bracket 112 and the transparent cover plate 180 are completed first, and the transmitter 120 and the receiver 130 are assembled on the first circuit board 150. Then, the isolator 190 is assembled on the lens 170 or the transparent cover plate 180. Finally, the first bracket 111, the second bracket 112 and the first circuit board 150 are assembled to obtain the detection component 100.

[0109] Please see Figure 12 , Figure 12 This is a structural disassembly diagram of the detection device 10 in some other embodiments of this application. The first circuit board 150 is provided with an abutment 195 on the side away from the first bracket 111. One end of the first elastic member 300 abuts against the abutment 195 and the other end abuts against the second housing 220.

[0110] The abutment 195 can be a structural reinforcement provided on the first circuit board 150. The abutment 195 can be a sheet-like structure, and its material can be metal, foam, rubber, or silicone, etc. Of course, in other embodiments, the abutment 195 can be omitted, meaning one end of the first elastic member 300 can directly abut against the first circuit board 150, and the other end can abut against the second housing 220. The first elastic member 300 can be a spring, foam, rubber, or silicone, etc. Preferably, the compression stroke of the first elastic member 300 is substantially the same as the movement stroke of the detection component 100 relative to the housing assembly 200. The first elastic member 300 can be an elastic body such as a flat compression spring.

[0111] Please see Figure 13 and Figure 14 , Figure 13 This is a structurally exploded schematic diagram of the detection device 10 in some other embodiments of this application. Figure 14 yes Figure 13 A schematic cross-sectional view of the detection device 10 in the embodiment. The housing assembly 200 may further include a second circuit board 230 disposed on the second housing 220. The second circuit board 230 is electrically connected to the first circuit board 150 to cooperate in completing the detection.

[0112] In this embodiment, one of the mating component 202 and the mating position 102 is disposed on the second circuit board 230, and the other is disposed on the second bracket 112. Of course, in other embodiments, one of the mating component 202 and the mating position 102 may be disposed on the first housing 210 or the second housing 220, and the other may be disposed on the first bracket 111 or the second bracket 112.

[0113] like Figure 13 and Figure 14 As shown, the example is provided with the mating part 202 located on the second circuit board 230 and the mating position 102 located on the second bracket 112.

[0114] The second circuit board 230 has a clearance hole 231, through which the detection component 100 passes and is movable relative to the housing assembly 200 in the axial direction of the clearance hole 231. The clearance hole 231 provides space for the movement of the detection component 100. The second circuit board 230 surrounds the periphery of the detection component 100, thereby preventing the detection component 100 from stacking with the second circuit board 230 and improving the structural compactness of the detection device 10. One end of the first elastic member 300 passes through the clearance hole 231 and abuts against the second housing 220.

[0115] Optionally, the second housing 220 has a clearance groove 221 on one side adjacent to the receiving cavity 204, which is opposite to the clearance hole 231. One end of the first elastic member 300 passes through the clearance hole 231 and abuts against the groove wall of the clearance groove 221. By providing the clearance groove 221 on the second housing 220, on the one hand, it can provide movement space for the detection component 100, and on the other hand, it can prevent the first elastic member 300 from being misaligned or shifted during deformation. Of course, in other embodiments, when the restoring force that causes the detection component 100 to move to the second position is magnetic, one of the first magnetic member 103 and the second magnetic member 203 is embedded in the clearance groove 221, and the other is disposed on the first circuit board 150.

[0116] Optionally, the second housing 220 may have a protrusion 221 on one side adjacent to the receiving cavity 204. The second circuit board 230 is disposed on the protrusion 221 and can be fixedly connected to the protrusion 221 by means of screwing, snap-fitting, welding, or bonding. Further, multiple protrusions 221 may be provided and arranged around the periphery of the clearance groove 221. Multiple protrusions 221 can enhance the connection stability of the second circuit board 230. Optionally, the first housing 210 may have a fixing post corresponding to the protrusion 221. This fixing post can pass through the second circuit board 230 and abut against the protrusion 221, and cooperate with the protrusion 221 to clamp and fix the second circuit board 230.

[0117] Understandably, the second circuit board 230 is electrically connected to the first circuit board 150 for signal transmission; that is, the second circuit board 230 and the first circuit board 150 cooperate to complete the detection. Of course, in other embodiments, the second circuit board 230 can be integrated onto the first circuit board 150, meaning the second circuit board 230 and the first circuit board 150 are combined into one. In this case, the mating part 202 or the mating position 102 can be provided on the first housing 210 or the second housing 220.

[0118] In one embodiment, the housing assembly 200 may further include a flexible circuit board 240, through which the second circuit board 230 and the first circuit board 150 are electrically connected. Of course, in other embodiments, the second circuit board 230 and the first circuit board 150 may also be electrically connected via wires. By using the flexible circuit board 240 or wires to electrically connect the second circuit board 230 and the first circuit board 150, the movement of the detection assembly 100 can be ensured to remain unaffected.

[0119] In some embodiments, one of the mating member 202 and the mating position 102 can be a snap-fit ​​element and the other can be a snap-fit ​​groove. The snap-fit ​​element can be a conductive element disposed on the second circuit board 230, such as a spring, a contact spring, or a POGO PIN. The snap-fit ​​element can be electrically connected to the second circuit board 230. The snap-fit ​​groove can be disposed on the bracket 110 (e.g., the second bracket 112), and the bracket 110 (e.g., the second bracket 112) can be made of a conductive material.

[0120] In some embodiments, the engaging member can be a telescopic structure. When the engaging member extends and engages with the engaging groove, the detection device 10 triggers a reminder to prompt the user to reduce the external force applied to the detection surface 101. In the first position, the engaging member is spaced apart from the inner wall of the engaging groove. In the second position, the engaging member abuts against the second support 112, meaning the engaging member can be electrically connected to the second support 112. Specifically, the second support 112 can be made of a conductive material, forming a circuit when the engaging member abuts against the second support 112; the circuit is broken when the engaging member enters the engaging groove and is spaced apart from the inner wall of the groove.

[0121] Optionally, the second bracket 112 may have two contacts spaced apart. When the engaging member abuts against the second bracket 112, the engaging member abuts against the two contacts on the second bracket 112 respectively to form a circuit. Optionally, there may be two engaging members; when the detection component 100 is in the second position, the two engaging members abut against the second bracket 112 respectively to form a circuit; when the detection component 100 is in the first position, the engaging member enters the corresponding engaging groove to break the circuit.

[0122] In one embodiment, one of the mating member 202 and the mating position 102 may be a conductive element, and the other may be an insulating element. The bracket 110 (e.g., the second bracket 112) may be made of a conductive material. Optionally, the mating member 202 may be a conductive element disposed on the second circuit board 230, such as a spring, a contact spring, or a POGO PIN. The mating position 102 may be an insulating element disposed on the second bracket 112, such as an insulating material coated on a portion of the surface of the second bracket 112. When the detection component 100 is in the second position, the mating member 202 abuts against the second bracket 112 to form a circuit; when the detection component 100 is in the first position, the mating member 202 abuts against the mating position 102 to break the circuit.

[0123] Optionally, the insulating part can be an insulator provided in the locking groove, so that the locking member is not electrically connected to the bracket after entering the locking groove, thereby disconnecting the above-mentioned circuit.

[0124] In summary, the disconnection of the circuit can trigger an electronic device to issue a reminder, such as a voice reminder or a text reminder displayed on the screen, to remind the user to reduce the pressure applied when pressing.

[0125] In one embodiment, both the mating member 202 and the mating position 102 can be conductive. For example, the mating member 202 can be a spring, a POGO pin, or a spring-loaded contact on the second circuit board 230 and electrically connected to the second circuit board 230. The mating position 102 can be a conductor on the second support 112, which can be made of an insulating material such as plastic. When the detection component 100 is in the first position, the mating member 202 abuts against the mating position 102 to form a circuit. When the detection component 100 is in the second position, the mating member 202 separates from the mating position 102 to break the circuit. At this time, in response to the connection of the circuit, the electronic device is triggered to issue a reminder, such as a voice reminder or a text reminder displayed on the screen, to remind the user to reduce the pressure applied during pressing.

[0126] In some embodiments, the bracket 110 (e.g., the second bracket 112) can also be connected to a circuit board, such as electrically connected to a second circuit board 230. Therefore, when the mating member 202 is electrically connected to the second bracket 112, a circuit can be formed. When the mating member 202 is not electrically connected to the second bracket 112 in the first position, the circuit is broken. In response to the break in the circuit, an electronic device is triggered to issue a reminder, such as a voice reminder or a text reminder displayed on a screen, to remind the user to reduce the pressure applied. In some embodiments, the bracket 110 (e.g., the second bracket 112) can also have a certain voltage, such as 3V. This allows the mating member 202 to detect the voltage value when it contacts the bracket 110, and to not detect the voltage when the mating member 202 is in the first position. This triggers the electronic device to issue a reminder to remind the user to reduce the pressure applied.

[0127] Understandably, the above method can also be used to implement a scheme in which the mating parts are set on the bracket and the mating position is set on the housing.

[0128] In some embodiments, the first bracket is movably connected to the first housing, allowing the detection component to move axially along the clearance hole of the second circuit board. The mating member can abut against the second bracket or separate from it. When abutting, signal conduction occurs between the mating member and the second bracket; when separated, i.e., when the mating member engages with the mating position, the signal connection between the mating member and the second bracket is broken. In this case, the disconnection of the signal can trigger an electronic device to issue a reminder, such as a voice reminder or a text reminder displayed on the screen, to remind the user to reduce the pressure applied.

[0129] Taking a locking component as the mating part and a locking groove as the mating position as an example, when the detection component moves axially upward along the clearance hole of the second circuit board due to the guiding action of the lead post, the locking component on the second circuit board can be a lateral contact spring. In the second position, the locking component abuts against the second bracket to achieve signal conduction; in the first position, the locking component enters the locking groove, causing the locking component to be spaced from the second bracket, thereby disconnecting the signal connection between the locking component and the second bracket. That is, the depth of the locking groove needs to be greater than the length of the portion of the locking component entering the locking groove, so that the locking component is spaced from the inner wall of the locking groove when it enters. In some embodiments, an insulator can be provided inside the locking groove so that the locking component is not electrically connected to the bracket after entering the locking groove.

[0130] Understandably, by setting up a detection component and a housing component that can move relative to each other, when the detection surface receives the force applied by the individual to be tested, causing the detection component to move to the first position, the engaging component can enter the engaging slot, thereby disconnecting the signal connection between the engaging component and the second support. This serves as a warning that the force on the detection surface is too great, which may cause excessive deformation of the individual's testing area and affect the accuracy of the detection results. At this point, it is necessary to reduce the force applied to the detection surface so that the detection component returns from the first position to the second position. When the engaging component returns to the second support, the signal between the engaging component and the second support is activated, thus indicating that testing can proceed.

[0131] Understandably, the signal conduction status between the locking component and the second support bracket indicates the stress on the detection surface, thus preventing excessive deformation of the surface of the object under test due to excessive stress, thereby ensuring the accuracy of the detection results.

[0132] Understandably, based on the technical inspiration of the above embodiments, when the detection surface is subjected to force and moves to the first position, i.e. the locking component is disconnected from the second bracket, the detection device can remind the user to lightly press their finger by not displaying detection information, flashing a light, emitting an alarm sound, or vibrating, so as to avoid excessive deformation of the surface of the individual to be tested due to excessive force, which would affect the accuracy of the measurement.

[0133] It should be noted that the above embodiments of this application provide at least two ways to indicate excessive force: one is to sense the force on the detection surface through touch, that is, to sense the change in resistance during the movement of the detection component; the other is to obtain the force on the detection surface through the cooperation relationship between the mating part and the mating position, that is, through the on and off of the electrical signal.

[0134] Based on the detection device provided in this application, compared with conventional finger-clip pulse oximeters, ultrasound detection devices, and electrocardiogram detection devices, by setting clearance holes on the second circuit board and allowing the detection components to move in the clearance holes and along the axial direction of the clearance holes, the stacking thickness of the detection device in the moving direction of the detection components can be reduced.

[0135] In addition, this application also provides electronic devices and wearable devices to integrate the above-mentioned detection device into electronic devices and wearable devices, so that the wearable devices and electronic devices can meet the health detection requirements while ensuring the compactness of the overall structure.

[0136] This application also provides a reminder method applied to an electronic device, the electronic device including a detection device, the detection device including: a detection component and a housing component capable of relative movement; one of the detection component and the housing component is provided with a mating position, and the other is provided with a mating part corresponding to the mating position; the detection component includes a detection surface for conforming to a user's detection part (understandably, the user will exert pressure on the detection surface during detection by contacting it, the detection part may be a part of the user's fingertip, etc.); the reminder method includes: when the mating position and the mating part are engaged, the electronic device issues a reminder, the reminder being used to prompt the user to reduce the external force applied to the detection surface.

[0137] It should be noted that the detection device included in the above-mentioned electronic device may include the technical features of any one or more of the foregoing embodiments, which will not be elaborated here.

[0138] The embodiments, implementation methods, and features of this application may be combined or substituted with each other without conflict.

[0139] As used herein, “electronic device” (or simply “terminal”) includes, but is not limited to, means configured to receive / transmit communication signals via a wired connection (such as via a Public Switched Telephone Network (PSTN), Digital Subscriber Line (DSL), Digital Cable, Direct Cable Connection, and / or another data connection / network) and / or via a wireless interface (e.g., for cellular networks, Wireless Local Area Networks (WLANs), Digital Television Networks such as DVB-H networks, Satellite Networks, AM-FM Broadcast Transmitters, and / or another communication terminal). A communication terminal configured to communicate via a wireless interface may be referred to as a “wireless communication terminal,” a “wireless terminal,” or a “mobile terminal.” Examples of mobile terminals include, but are not limited to, satellite or cellular phones; personal communication system (PCS) terminals that may combine cellular radiotelephone with data processing, fax, and data communication capabilities; PDAs that may include radiotelephones, pagers, Internet / intranet access, web browsers, notepads, calendars, and / or Global Positioning System (GPS) receivers; and conventional laptop and / or handheld receivers or other electronic devices that include radiotelephone transceivers. A mobile phone is an electronic device equipped with a cellular communication module.

[0140] As used herein, "wearable device" refers to a device with information processing capabilities and that meets the basic technical requirements for wearable devices. In this embodiment, in addition to indicating the time, the wearable device should also have one or more functions such as reminders, navigation, calibration, monitoring, and interaction. For example, the wearable device may have Bluetooth data transmission standard to achieve collaborative interaction capabilities. It may also have various monitoring sensors, such as sensors that monitor ambient light, geomagnetism, temperature, air pressure, altitude, gyroscopes, accelerometers, and heart rate. Furthermore, the display method of the wearable device may include pointers, numbers, and images.

[0141] Electronic devices can include various handheld devices, vehicle-mounted devices, wearable devices or wearable devices with wireless communication capabilities, computing devices or other processing devices connected to a wireless modem, as well as various forms of user equipment (UE), mobile station (MS), terminal device, etc. For ease of description, the devices mentioned above are collectively referred to as electronic devices.

[0142] The wearable device or wearable apparatus can be a smart bracelet, smartwatch, virtual reality (VR) glasses, augmented reality (AR) glasses, smart ankle bracelet, smart belt, etc., and is not limited here. As long as the wearable device or apparatus can be worn on the human body, it can be understood as a wearable device or apparatus of this application. For ease of explanation, the wearable device or apparatus in the embodiments of this application is described using a smartwatch as an example.

[0143] Please see Figure 15 , Figure 15 This is a schematic diagram of the structure of a wearable device 50 in some embodiments of this application. The wearable device 50 provided in this application embodiment can be a smartwatch or a smart bracelet, which can be worn on the user's wrist for use. Besides providing users with services such as calendar and time viewing, it can also provide communication services such as voice calls and video chats, and can monitor the user's daily exercise, physical health, and other data indicators. For example, the wearable device 50 can be equipped with detection modules such as photoplethysmography (PPG) and electrocardiography (ECG) to realize the function of detecting the user's health status. Of course, the functions of the wearable device 50 are not limited to these; this embodiment will not list them all, and the following description uses a smartwatch as an example.

[0144] like Figure 15 As shown, the wearable device 50 may include an electronic device 510 and a strap 520. Straps 520 are provided on opposite sides of the electronic device 510, and the electronic device 510 may be equipped with a PPG detection module, which can be used to realize the health monitoring function of the wearable device 50. The straps 520 on opposite sides can be connected, and after connection, they can form a wearing space together with the electronic device 510, allowing the user to wear the electronic device 510 on their wrist for use. Specifically, the electronic device 510 can be the watch head of a smartwatch, and the strap 520 can be the watch band of a smartwatch. In addition to the PPG detection module, the electronic device 510 may also be equipped with other electronic components required by a smartwatch, such as a battery, camera, speaker, and microphone. The strap 520 can be made of a flexible, skin-friendly material, such as soft rubber, silicone, hemp rope, or composite materials, to improve user comfort. Of course, the strap 520 can also be made of metal.

[0145] In some embodiments, the electronic device 510 may not be limited to use in the wearable device 50, i.e., a smartwatch; it may also be a standalone device, such as a professional medical device or health monitoring device. Alternatively, the electronic device 510 may also be a mobile phone, tablet computer, or laptop computer with health monitoring functions, etc., and this embodiment does not limit this. In other words, the electronic device 510 can be used to implement the health monitoring function of the wearable device 50. Of course, in other embodiments, the electronic device 510 can implement the health monitoring function independently.

[0146] See also Figure 16 , Figure 16 This is a structurally exploded schematic diagram of an electronic device 510 in some embodiments of this application. The electronic device 510 may include a display screen 511, a housing assembly 512, and a detection assembly 513. The display screen 511 may be connected to the housing assembly 512, and the two may together enclose a receiving space. The housing assembly 512 has a receiving space 101 with one open end, and the display screen 511 covers the open end and is connected to the housing assembly 512. The detection assembly 513 may be disposed within the receiving space, and the detection assembly 513 may be used to emit detection signals and receive detection signals reflected back by the user's body. The detection signals may be light signals, ultrasonic signals, or electrical signals, etc.

[0147] The display screen 511 enables the image display function of the electronic device 510, facilitating human-computer interaction between the user and the electronic device 510. The detection component 513 can be a PPG detection module, which analyzes probe light carrying information about the user's body tissue, thereby enabling the health detection function of the electronic device 510. The housing component 512 protects the electronic components within the housing space 101. Alternatively, in other embodiments, the detection component 513 can be an ultrasonic detection module, which analyzes ultrasonic signals carrying information about the user's body tissue, thereby enabling the health detection function of the electronic device 510. Furthermore, the detection component 513 can be an ECG detection module, which analyzes electrical signals carrying information about the user's body tissue, thereby enabling the health detection function of the electronic device 510.

[0148] Specifically, the display screen 511 may include a transparent panel, a display panel, and a touch panel stacked together, with the touch panel disposed between the transparent panel and the display panel. The transparent panel can be used to protect the display panel and serves as the outer surface of the electronic device 510. The display panel can be used for image display. The touch panel can be used to implement human-computer interaction functions. The transparent panel, display panel, and touch panel can be bonded together using adhesives such as optical adhesives and pressure-sensitive adhesives.

[0149] Specifically, the surface of the transparent panel can be smooth and flat to facilitate touch operations such as clicking, swiping, and pressing. The transparent panel can be made of rigid materials such as glass, or flexible materials such as polyimide (PI) or colorless polyimide (CPI). The display panel is primarily used to display images and can also serve as an interactive interface to guide users to perform the aforementioned touch operations on the transparent cover.

[0150] The display panel can use either an OLED (Organic Light-Emitting Diode) panel or an LCD (Liquid Crystal Display) panel for image display. The touch panel primarily responds to user touch operations, converting these operations into electrical signals that are transmitted to the processor of the electronic device 510, enabling the electronic device 510 to react accordingly to the user's touch actions.

[0151] The above is only a brief description of the basic structure and function of the display screen 511. For the specific structure and implementation principle of the display screen 511, please refer to the existing technology, which will not be elaborated here.

[0152] The housing assembly 512 may include a rear cover and a mid-frame disposed on one side of the rear cover. The display screen 511 may be disposed on one side of the mid-frame, and the rear cover may be disposed on the opposite side of the mid-frame. The rear cover and the mid-frame together form an open-end receiving space. That is, the rear cover, the mid-frame, and the display screen 511 together form a receiving space. This receiving space can be used to install other electronic components required by the electronic device 510, such as batteries, cameras, speakers, and microphones. The display screen 511 and the rear cover may be fixedly connected to the mid-frame by adhesive and / or connecting plates, respectively. Of course, the connection method of the display screen 511 and the rear cover is not limited to this; this embodiment does not limit it.

[0153] The middle frame can resemble a square with rounded corners in shape, and it can be used to mount electronic components of the electronic device 510, fixing the electronic components within the receiving space 101. For example, the speaker of the electronic device 510 can be fixed to the middle frame, and the middle frame can also have corresponding sound-emitting holes to connect the speaker to the outside of the receiving space 101, allowing the speaker to emit sound through the sound-emitting holes. Simultaneously, the opposite sides of the middle frame can also be used to connect with the strap 520. For example, spring-ear holes can be provided on the opposite sides of the middle frame, and a spring-ear pin can be provided at one end of the strap 520, allowing the strap 520 to be detachably connected to the middle frame via the spring-ear pin. Furthermore, the material of the middle frame can be metal or rigid plastic, or it can be formed from both metal and rigid plastic. For example, the middle frame can be divided into an inner shell and an outer shell; the inner shell can be made of rigid plastic, and the outer shell can be made of metal, and the inner shell and outer shell can be integrally molded using an in-mold injection molding process. This not only gives the middle frame high structural strength but also reduces its weight. Optionally, the connection method between the middle frame and the strap 520 is not limited to the aforementioned spring bar pins. The two can also adopt other detachable connection methods, or they can be fixedly connected and not detachable. At the same time, the shape of the middle frame can also be circular, oval, or other shapes. Its specific shape can be adjusted according to design requirements, and this embodiment does not limit it in this way.

[0154] The rear cover of the housing assembly 512 may have a through hole 514, and one end of the detection assembly 513 may pass through the through hole 514. The detection surface of the detection assembly 513 is formed on the end of the detection assembly 513 that passes through the through hole 514. The rear cover of the housing assembly 512 may be the first housing 210 in the aforementioned embodiment, and the through hole 514 may be the through hole 205 in the aforementioned embodiment.

[0155] Furthermore, the specific structural features of the housing assembly 512 and the detection assembly 513 can be referred to the housing assembly 200 and the detection assembly 100 in the foregoing embodiments, and therefore will not be repeated here.

[0156] The detection device and electronic equipment provided in this application sense the force on the detection surface by setting the detection component to move relative to the housing component, so as to avoid excessive deformation of the surface of the object under test due to excessive force, thereby ensuring the accuracy of the detection results.

[0157] The terms "comprising" and "having," and any variations thereof, in this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or device that includes a series of steps or units is not limited to the steps or units listed, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or devices.

[0158] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
