[0046] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0047] 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.

[0048] In this application, unless otherwise expressly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0049] Furthermore, the use of terms such as "first" and "second" in this application is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the word "and / or" throughout the text means including three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution that simultaneously satisfies A and B. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed in this application.

[0050] Currently, detection devices such as smart bracelets are increasingly being designed to detect vibration parameters of the human body, such as heart rate and pulse, to monitor the user's health. These devices typically include a mounting carrier and a vibration transducer fixedly mounted on the carrier. Because the vibration sensor is fixed, the mounting carrier acts as a limiter, and the vibration signals from the human heart and pulse are relatively weak. Therefore, during operation, these vibration signals are easily absorbed by the mounting carrier, resulting in low detection accuracy.

[0051] Therefore, based on the above considerations, in order to solve the problem of low detection accuracy of vibration signals in current detection devices, this application proposes a novel detection device. This detection device innovatively places a movable vibration detection component on a mounting carrier, and sets a support structure between the carrier and the vibration detection component that can apply a reset force to the vibration detection component. This allows the vibration detection component to vibrate in sync with the vibration signal during detection, thereby restoring the characteristics of the vibration signal and improving its detection accuracy.

[0052] Furthermore, it should be noted that the detection device proposed in this application can be a smart wearable product, such as a smart bracelet or smartwatch. Of course, it can also be a handheld detection product. Therefore, this application does not limit the product type of the detection device. Additionally, the detection device can be used to detect the vibration signal of the heart, or it can be used to detect the vibration signal of the pulse; this application also does not limit the object to be detected by the detection device.

[0053] The structure of the detection device proposed in this application will be explained and described below with reference to the embodiments. Figures 1 to 5In one embodiment of this application, the detection device 100 proposed in this application includes a mounting carrier 10, a vibration detection element 20, and a support structure 30. The vibration detection element 20 is movably disposed on the mounting carrier 10 along a first direction; the support structure 30 is disposed between the mounting carrier 10 and the vibration detection element 20, and can apply a reset force to the vibration detection element 20 in the first direction.

[0054] The mounting carrier 10 provides a mounting position for mounting the vibration detection element 20, the support frame structure, and other components of the detection device 100, thereby facilitating the assembly of the various components of the detection device 100 into a whole. The mounting carrier 10, as described below, is a shell structure, but it can also be a plate structure or a base structure; this application does not limit the structural type of the mounting carrier 10. Furthermore, on the projection plane perpendicular to the first direction, the projection of the mounting carrier 10 can be rectangular, square, or circular, etc. Therefore, this application does not limit the shape of the mounting carrier 10.

[0055] The vibration detection element 20 can be used to detect vibration signals. This vibration detection element 20 can be a vibration sensor or a microphone sensor, ensuring that it can identify vibration signals after contact with a human body. Furthermore, the vibration detection element 20 can be connected to the support structure 30 or to the mounting carrier 10. In addition, the number of vibration detection elements 20 can be one, two, or more.

[0056] The support structure 30 can apply a reset force to the vibration detection element 20, so that the vibration detection element 20 can vibrate in accordance with the detected vibration signal when the detection device 100 is working. The support structure 30 can be a first magnetic element 31 and a second magnetic element 32, as described below, to apply a reset force to the vibration detection element 20 through the repulsive magnetic force between them. Alternatively, the support structure 30 can include an elastic element to apply a reset force to the vibration detection element 20 through elastic force. Therefore, this application does not limit the structural type of the support structure 30, as long as it enables the vibration detection element 20 to vibrate in accordance with the vibration signal on the mounting carrier 10. Furthermore, the number of support structures 30 can correspond to the number of vibration detection elements 20. Alternatively, at least two vibration detection elements 20 can share one support structure 30; or, one vibration detection element 20 can be supported by at least two support structures 30.

[0057] The detection device 100 of this application configures the vibration detection element 20 to be movable relative to the mounting carrier 10 along a first direction, and provides a support structure 30 between the two to apply a reset force to the vibration detection element 20. This allows the vibration detection element 20 to fit closely to the human body during detection, for example, when it is attached to the human body to detect heart vibration, and to move accordingly with the heart's vibration. This allows the detection device 100 to reproduce the characteristics of the heart's vibration movement during the detection process, thereby improving the detection accuracy of the vibration signal.

[0058] Please refer to the reference. Figures 3 to 5 In one embodiment of this application, the support structure 30 includes a first magnetic element 31 and a second magnetic element 32. The first magnetic element 31 is disposed on the mounting carrier 10; the second magnetic element 32 is disposed on the vibration detection element 20 and is spaced apart from the first magnetic element 31 in a first direction. The second magnetic element 32 and the first magnetic element 31 are configured to form a repulsive force (e.g., Figure 5 (F1 shown in the figure).

[0059] The first magnetic element 31 can be a permanent magnet to simplify its structure. Alternatively, it can be an electromagnet. The connection between the first magnetic element 31 and the mounting carrier 10 can be achieved through adhesive bonding to simplify the connection process and improve stability. Alternatively, the connection can be achieved through clamping or screws; this application does not limit the connection method between the first magnetic element 31 and the mounting carrier 10. Furthermore, on a projection plane perpendicular to the first direction, the projection of the first magnetic element 31 can be circular, square, or rectangular, etc.; this application does not limit the shape of the first magnetic element 31.

[0060] The second magnetic element 32 can be a permanent magnet to simplify its structure. Alternatively, it can be an electromagnet. The connection between the second magnetic element 32 and the vibration detection element 20 can be achieved through adhesive bonding to simplify the connection process and improve stability. The connection between the first magnetic element 31 and the vibration detection element 20 can also be achieved through clamping or screws; this application does not limit the connection method between the second magnetic element 32 and the vibration detection element 20. Furthermore, on the projection plane perpendicular to the first direction, the projection of the second magnetic element 32 can be circular, square, or rectangular; this application does not limit the shape of the second magnetic element 32. Additionally, on the projection plane perpendicular to the first direction, the projection planes of the second magnetic element 32 and the first magnetic element 31 can be equal or different; this application does not limit this, as long as they can be positioned relative to each other.

[0061] In this embodiment, the support structure 30 includes a first magnetic element 31 and a second magnetic element 32, allowing the vibration detection element 20 to be suspended in the first direction when the detection device 100 is operating. This allows it to primarily detect the human body, further reducing contact interference from external sources such as the mounting carrier 10, and further improving the detection accuracy of the vibration signal by the detection device 100. Simultaneously, the support structure 30 has a relatively simple structure and small size, which facilitates its manufacturing and installation.

[0062] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the support structure 30 further includes a third magnetic element 33, which is disposed on the mounting carrier 10; the third magnetic element 33 and the second magnetic element 32 are configured to form an attractive force (e.g., Figure 5 As shown in F2), the vibration detection element 20 and the mounting carrier 10 are spaced apart in the first direction.

[0063] The third magnetic element 33 can be a permanent magnet to simplify its structure. Alternatively, it can be an electromagnet. Furthermore, the third magnetic element 33 can be ring-shaped, arc-shaped, or linear, and at least two can be provided. The third magnetic element 33 can be located on the side of the second magnetic element 32 facing the first magnetic element 31, or it can be located on the side of the second magnetic element 32 away from the first magnetic element 31. The connection between the third magnetic element 33 and the mounting carrier 10 can be achieved through adhesive bonding to simplify the connection process and improve connection stability. Alternatively, the connection between the first magnetic element 31 and the mounting carrier 10 can be achieved through clamping or screw connections; this application does not limit the connection method between the second magnetic element 32 and the mounting carrier 10.

[0064] In this embodiment, when the detection device 100 is working, the repulsive force F1 between the first magnetic element 31 and the second magnetic element 32, the attractive force F2 between the third magnetic element 33 and the second magnetic element 32, and the pressing force F3 exerted by the human body on the vibration detection element 20 can achieve force balance in the first direction. When the detection device 100 is not working, the pressing force F3 exerted by the human body on the vibration detection element 20 disappears, and the repulsive force F1 between the first magnetic element 31 and the second magnetic element 32 can drive the vibration detection element 20 to reset until the components of the repulsive force F1 between the first magnetic element 31 and the second magnetic element 32 and the attractive force F2 between the third magnetic element 33 and the second magnetic element 32 in the first direction are equal. It can be seen that the setting of the third magnetic element 33 eliminates the need for a stop and limit structure on the mounting carrier 10 for the vibration detection element 20 in the first direction, achieving complete spacing between the vibration detection element 20 and the mounting carrier 10 in the first direction, improving the suspended installation effect of the vibration detection element 20, and further reducing the contact interference of the mounting carrier 10 on the vibration detection element 20. Of course, in other embodiments, when the support structure 30 is not provided with the third magnetic element 33, the mounting carrier 10 can provide a stop and limit structure on the side of the vibration detection element 20 away from the first magnetic element 31, such as a stop block or a stop post.

[0065] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the third magnetic element 33 is ring-shaped and surrounds the center line of the first magnetic element 31 and the second magnetic element 32 in a first direction.

[0066] In this embodiment, the third magnetic element 33 is configured as a ring shape and surrounds the first magnetic element 31 and the second magnetic element 32, so that the third magnetic element 33 can apply attractive forces at various points around the circumference of the second magnetic element 32. This improves the uniformity of force on the vibration detection element 20, thereby further improving the detection accuracy of the detection device 100 for vibration signals. Furthermore, since the support structure 30 contains only one third magnetic element 33, it facilitates the assembly of the detection device 100. Of course, in other embodiments, as described above, the third magnetic element 33 can also be an arc shape or a linear segment. In this case, at least two third magnetic elements 33 can be spaced apart circumferentially along the first magnetic element 31 and the second magnetic element 32.

[0067] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, on a projection surface perpendicular to the first direction, the projection area of ​​the first magnetic element 31 is smaller than the projection area of ​​the third magnetic element 33, and the projections of the first magnetic element 31 and the third magnetic element 33 partially overlap.

[0068] In this embodiment, the projections of the first magnetic element 31 and the third magnetic element 33 are partially overlapped, which improves the compactness of their distribution and reduces the volume of the support structure 30, thus improving the ease of installation within a limited space. Simultaneously, it also facilitates the first magnetic element 31 covering the corresponding second magnetic element 32, thereby creating a sufficient repulsive force on the second magnetic element 32.

[0069] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, on a projection plane perpendicular to the first direction, the projection of the second magnetic element 32 is located inside the projection of the third magnetic element 33.

[0070] In this embodiment, the projection of the second magnetic element 32 is positioned inside the projection of the third magnetic element 33, so that the third magnetic element 33 can exert an attractive force on the second magnetic element 32 in both the first direction and the second direction intersecting the first direction, thereby improving the limiting effect on the vibration detection element 20 and improving the accuracy and stability of the movement of the vibration detection element 20 in the first direction.

[0071] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the projections of the first magnetic element 31, the second magnetic element 32, and the third magnetic element 33 are all circular on the projection plane perpendicular to the first direction.

[0072] In this embodiment, the first magnetic element 31, the second magnetic element 32, and the third magnetic element 33 are all circular, which makes their periphery consistent and improves the uniformity of force distribution. At the same time, it also makes their volume relatively small and regular, thereby improving the convenience of their manufacturing and assembly.

[0073] Please refer to the reference. Figure 4 and Figure 5 In one embodiment of this application, the third magnetic element 33 is located on the side of the second magnetic element 32 facing the first magnetic element 31.

[0074] In this embodiment, the third magnetic element 33 is disposed on the side of the second magnetic element 32 facing the first magnetic element 31, so that the vibration detection element 20 can be well protruded on the mounting carrier 10 and make accurate contact with the human body when the volume is relatively small, thereby helping to reduce the volume of the detection device 100 and improve the convenience of subsequent use.

[0075] Please refer to the reference. Figure 4 and Figure 5In one embodiment of this application, the vibration detection element 20 is provided with a detection surface 20a and a back surface 20b, the back surface 20b and the detection surface 20a are arranged back to back, and the second magnetic element 32 is provided on the back surface 20b.

[0076] In this embodiment, the detection surface 20a, which is the surface that can be used to contact the human body, has the second magnetic element 32 disposed on the opposite side 20b. This can improve the correspondence between the vibration detection element 20 and the support structure 30, thereby improving the uniformity of the force on the vibration detection element 20 and thus improving the detection accuracy of the vibration signal.

[0077] In one embodiment of this application, the support structure 30 includes an elastic element.

[0078] In this embodiment, the elastic element can be a spring or a sheet. This simplifies the number of components in the support structure 30. Alternatively, the support structure 30 can further include a telescopic rod, which can be inserted into the elastic element to guide its elastic force.

[0079] Please refer to Figure 3 In one embodiment of this application, the number of vibration detection elements 20 is at least two, and the at least two vibration detection elements 20 are arranged side by side in a second direction intersecting the first direction; the number of support structures 30 is at least two, and each support structure 30 is disposed between the mounting carrier 10 and the vibration detection element 20.

[0080] In this embodiment, the number of vibration detection elements 20 is set to at least two, so that vibration signals can be detected by at least two vibration detection elements 20. This enriches the detection data, reduces the influence of randomness and error, and thus helps to further improve the accuracy of the detection results. The corresponding arrangement of the number of support structures 30 and the number of vibration detection elements 20 facilitates the application of the required reset force to each vibration detection element 20, and also facilitates the arrangement of the vibration detection elements 20 and the support structures 30. The at least two vibration detection elements 20 can be arranged in a rectangular array, or in a circular array, or in other forms.

[0081] Please refer to the reference. Figures 3 to 5 In one embodiment of this application, the detection device 100 further includes a control board 40 and a signal line 50. The control board 40 is disposed on the mounting carrier 10, and the signal line 50 is wavy or spiral and electrically connected to the vibration detection element 20 and the control board 40.

[0082] In this embodiment, the control board 40 can control the operation of the vibration detection element 20, and can receive, process, and store the signals transmitted by the vibration detection element 20. The signal line 50 can be used as a carrier for signal transmission. Setting the signal line 50 to a wavy or spiral shape can prevent the vibration detection element 20 from being stretched during the vibration process following the vibration signal, thus improving the accuracy of the vibration detection element 20 in detecting the vibration signal. It also reduces the possibility of the signal line 50 being damaged by stretching. The signal line 50 can be an FPC flexible cable to facilitate bending and improve its layout. Of course, the signal line 50 can also be a single-strand structure.

[0083] Please refer to the reference. Figures 3 to 5 In one embodiment of this application, the detection device 100 further includes a fixing strap 60, which is connected to the mounting carrier 10.

[0084] In this embodiment, by providing a fixing strap 60, the detection device 100 can be configured as a smart wearable product, such as a smart bracelet or smartwatch, thus facilitating its use. The fixing strap 60 can be one. In this case, one end of the fixing strap 60 is connected to the mounting carrier 10, and the other end is detachably connected to the mounting carrier 10 via a snap-fit ​​or magnetic connection. Alternatively, the fixing strap 60 can be two. In this case, one end of the two fixing straps 60 can be connected to opposite sides of the mounting carrier 10, and the ends of the two fixing straps 60 furthest from the mounting carrier 10 can be detachably connected via a snap-fit ​​or magnetic connection.

[0085] Please refer to Figure 3 In one embodiment of this application, the detection device 100 further includes an electrocardiogram (ECG) sensor 70, which is disposed on the mounting carrier 10.

[0086] In this embodiment, the ECG sensor 70 is used as a supplementary auxiliary detection method. After the detection device 100, as a smart product, is clamped between the arm and body, it can collect blood pressure and oxygenation information of the arm, further improving the detection device 100's ability to collect human health parameters. To facilitate the placement of the ECG sensor 70 and the vibration detection element 20, and to facilitate contact detection between them and the human body, in one embodiment of this application, the ECG sensor 70 and the vibration detection element 20 can be located on opposite sides of the mounting carrier 10. Furthermore, the fixing strap 60 and the side of the mounting carrier 10 where the ECG sensor 70 is located can form a wearing space to allow the user's hand to pass through for wearing. When the detection device 100 includes a control board 40 as described above, the ECG sensor 70 can be electrically connected to the control board 40, and it and the vibration detection element 20 can be located on opposite sides of the control board 40.

[0087] Please refer to Figure 3 In one embodiment of this application, the mounting carrier 10 is provided with a mounting cavity (not shown), and the vibration detection element 20 and the support structure 30 are both provided in the mounting cavity (not shown); the mounting carrier 10 is also provided with a first connecting hole 10b communicating with the mounting cavity (not shown), the vibration detection element 20 is provided with a detection surface 20a, and one end of the vibration detection element 20 with the detection surface 20a extends out from the first connecting hole 10b.

[0088] In this embodiment, both the vibration detection element 20 and the support structure 30 are housed within the mounting cavity (not shown), which improves their compact distribution on the mounting carrier 10. Simultaneously, the mounting cavity (not shown) also protects the vibration detection element 20 and the support structure 30, and enhances the aesthetics of the detection device 100, thereby increasing the market competitiveness of subsequent products. When the detection device 100 also includes a control board 40 and an ECG sensor 70 as described above, the control board 40 and the ECG sensor 70 can also be housed within the mounting cavity (not shown). The mounting carrier 10 may also have a second connecting hole 10c communicating with the mounting cavity (not shown), through which a portion of the ECG sensor 70 can extend.

[0089] Please refer to the reference. Figures 3 to 5 In one embodiment of this application, the mounting carrier 10 includes an outer shell 11 and an inner carrier 13. The outer shell 11 is provided with a mounting cavity (not shown) and a first connecting hole 10b. The inner carrier 13 is disposed in the mounting cavity (not shown), and the vibration detection element 20 and the support structure 30 are disposed in the inner carrier 13.

[0090] In this embodiment, the inner carrier 13 can be a plate structure, including a single plate or at least two plates. Since the inner carrier 13 is simpler in structure and smaller in size than the outer shell 11, it facilitates the installation of the vibration detection element 20 and the support structure 30 on the inner carrier 13, which are then installed into the outer shell 11 all at once. To further improve installation convenience, the control board 40 can also be installed on the side of the inner carrier 13 away from the vibration detection element 20, and the ECG sensor 70 can be installed on the side of the control board 40 away from the inner carrier 13. Additionally, the outer shell 11 can include an upper shell 111 and a lower shell 112, which together form a mounting cavity (not shown). The upper shell 111 may have a first connecting hole 10b, and the lower shell 112 may have a second connecting hole 10c.
