Description

Technical Field

[0001] The present disclosure relates to the field of biomedical engineering industry, and in particular to a monitoring device. Background Art

[0002] A glucose monitor is a device used to continuously monitor a person's blood sugar concentration, enabling the user to adjust blood sugar concentrations in a timely manner, such as by adjusting diet or taking medication, thereby reducing the risk of complications caused by abnormal blood sugar concentrations.

[0003] Glucose monitors usually include electronic devices and sensors connected to the electronic devices. The sensors are placed under the skin to monitor the glucose concentration in the human body. In order to save costs, the glucose monitor can be designed in a split type, which is divided into a reusable part containing electronic devices and a disposable part containing sensors. After use, users can discard the disposable part and keep the reusable part for reuse, thereby reducing the economic burden.

[0004] In existing split-type glucose monitors, if the sealing effect after assembly of reusable components and disposable components is not good, pollutants from the external environment (especially liquid pollutants) may enter the interior of the split-type glucose monitor, causing short circuits in electronic devices or decreased sensor sensitivity, etc., resulting in poor stability in the use of the split-type glucose monitor. Summary of the invention

[0005] The present disclosure is proposed in view of the above-mentioned prior art conditions, and its purpose is to provide a monitoring device with good sealing performance.

[0006] To this end, the present disclosure provides a monitoring device, which is a monitoring device for obtaining physiological parameter information of a host, comprising a first shell, a second shell, a seal and a snap-fitting portion, wherein the first shell is provided with a sensor for obtaining physiological information of the host, and the second shell is provided with an electronic device, and the first shell and the second shell are detachably assembled through the snap-fitting portion, and during assembly, the sensor is electrically connected to the electronic device, the seal is located between the first shell and the second shell and is squeezed, and the snap-fitting portion comprises a first joining feature and a second joining feature, the first joining feature has a recessed structure or a raised structure, and the second joining feature has a recessed structure or a raised structure corresponding to the first joining feature, the first joining feature is arranged on the first shell, and the second joining feature is arranged on the second shell, the number of the snap-fitting portions is multiple, and the multiple snap-fitting portions are distributed at both ends and both sides of the central axis of the monitoring device.

[0007] In the monitoring device involved in the present disclosure, by arranging a seal between the first shell and the second shell and squeezing the seal when the first shell and the second shell are in the assembled state, it is possible to facilitate the seal to be in close contact with the first shell and the second shell, thereby improving the sealing of the monitoring device, thereby reducing the possibility of the internal components of the monitoring device being disturbed by the external environment (for example, reducing the possibility of short circuit of electronic devices or reduction of sensor sensitivity when wearing the monitoring device on rainy days or in the shower), thereby facilitating the normal operation and service life of the monitoring device; by arranging multiple clamping parts, the assembly stability of the first shell and the second shell can be improved, which is conducive to reducing the assembly gap between the first shell and the second shell. In addition, multiple clamping parts are arranged at both ends and both sides of the central axis of the monitoring device, and the multiple clamping parts can provide clamping forces for the combination of the two shells from multiple directions, so that multiple positions of the seal can be subjected to strong squeezing force and in close contact with the two shells, which is conducive to further improving the sealing of the monitoring device. Thus, a monitoring device with good sealing can be provided.

[0008] In addition, in the monitoring device involved in the present disclosure, optionally, at least one of the multiple engaging parts is a main engaging part, and the first engaging feature of the main engaging part is configured to be displaceable, and the displaceable first engaging feature includes a locked state and an unlocked state. When the first shell is assembled to the second shell, the displaceable first engaging feature is in the locked state, and under the action of an external force, the displaceable first engaging feature is displaced and transformed into the unlocked state to release the second shell. In this case, the displaceable first engaging feature can be deflected when subjected to an external force, which can facilitate switching between the locked state and the unlocked state, thereby facilitating the disassembly and assembly of the first shell and the second shell.

[0009] In addition, in the monitoring device involved in the present disclosure, optionally, the second engagement feature of the main engaging portion has a guide surface, and during the assembly process of the first shell and the second shell, the guide surface contacts the first deflectable engagement feature and guides the first deflectable engagement feature to the unlocked state. In this case, the assembly of the first shell and the second shell can be facilitated by the cooperation between the guide surface and the first deflectable engagement feature.

[0010] In addition, in the monitoring device involved in the present disclosure, optionally, during the assembly process of the first shell and the second shell, the surface of the first deflectable engagement feature in contact with the guide surface is an inclined surface or a curved surface. In this case, the guiding effect of the guide surface when the first deflectable engagement feature is deflected can be further improved, so that the first deflectable engagement feature is easier to deflect. In addition, since the second shell can be recycled and reused, setting the surface of the first deflectable engagement feature in contact with the guide surface during the assembly process to an inclined surface or a curved surface can reduce the wear on the second engagement feature, thereby facilitating the maintenance of the service life of the second shell.

[0011] In addition, in the monitoring device involved in the present disclosure, optionally, the first deflectable engagement feature has a pressing portion extending outward along the central axis. In this case, the pressing portion can increase the force application space when the host applies force to the first deflectable engagement feature. When it is necessary to apply force to the first deflectable engagement feature to turn it into an unlocked state, the first deflectable engagement feature can be deflected by applying force to the pressing portion, thereby improving the convenience of the host in disassembling and assembling the monitoring device.

[0012] In addition, in the monitoring device involved in the present disclosure, optionally, the first shell includes a first substrate, the edge of the first substrate is surrounded by an extension portion extending in a direction having a predetermined angle with the first substrate, the extension portion includes a first part and a second part, the first displaceable engagement feature is arranged in the first part, and there is a gap between the first part and the second part. In this case, during assembly, the extension portion can make the first shell surround and wrap the second shell, thereby improving the sealing between the first shell and the second shell. In addition, since the displaceable first engagement feature is displaced by an external force, the displaceable first engagement feature needs to be deflected outward to a certain extent in order to provide a moving space for the second engagement feature, therefore, the first engagement feature is arranged on the first part without affecting the wrapping of the second shell by the second part (i.e., without affecting the sealing between the first shell and the second shell), and the gap can provide convenience for the displaceable first engagement feature when it is displaced.

[0013] In addition, in the monitoring device involved in the present disclosure, optionally, at least one of the multiple engaging parts is a secondary engaging part, the secondary engaging part is arranged at an end opposite to the main engaging part, the first engaging feature of the secondary engaging part is located in the second part, and the first engaging feature of the secondary engaging part is a through hole that penetrates the second part, and when the first shell is assembled to the second shell, the second engaging feature in the secondary engaging part is engaged with the first engaging feature and protrudes from the second part. In this case, when the first shell is assembled to the second shell, the second engaging feature in the secondary engaging part protrudes from the second part (that is, the second engaging feature protrudes from the through hole), so that the secondary engaging part can provide a stronger engaging strength, which is conducive to improving the assembly stability of the first shell and the second shell.

[0014] In addition, in the monitoring device involved in the present disclosure, optionally, the engaging parts located on both sides of the central axis of the monitoring device are side engaging parts, and the length and depth of the first engaging feature and the second engaging feature in the side engaging parts are smaller than the length and depth of the first engaging feature and the second engaging feature in the engaging parts located at both ends of the central axis of the monitoring device. In this case, the engaging force provided by the side engaging parts during assembly is smaller than the engaging forces provided by the main engaging parts and the auxiliary engaging parts during assembly, respectively, thereby reducing the possibility that the first shell and the second shell are not convenient to disassemble due to the excessive engaging force on the monitoring device in the direction of the central axis and in the direction perpendicular to the central axis; that is, if the monitoring device is subjected to large engaging forces in the direction of the central axis and in the direction perpendicular to the central axis, it is necessary to apply a certain force to all the engaging parts in the direction of the central axis and in the direction perpendicular to the central axis at the same time during disassembly to release the engaging state. In the present disclosure, by providing the side engaging parts, the force required in the direction perpendicular to the central axis can be reduced, thereby facilitating the disassembly of the two shells.

[0015] In addition, in the monitoring device involved in the present disclosure, optionally, the electronic device includes an electrical connection portion electrically connected to the sensor, and the sealing member is provided on the second shell and wraps the electronic device in a manner of exposing the electrical connection portion. In this case, the sealing performance of the sealing member to the electronic device can be improved, and when the first shell and the second shell are assembled, the electronic device can be electrically connected to the sensor through the exposed electrical connection portion.

[0016] In addition, in the monitoring device involved in the present disclosure, optionally, the sealing member is elastic and is arranged on the second shell, and the sealing member protrudes from the second shell in the assembly direction of the second shell and the first shell, and when the first shell and the second shell are assembled, the sealing member is squeezed by the first shell and the second shell to produce deformation. In this case, the sealing member protruding from the second shell is conducive to the close contact between the sealing member and the second shell during assembly, and when the first shell and the second shell are assembled through the snap-fitting portion, the sealing member is squeezed by the first shell and the second shell to produce deformation, so that the sealing member can better adapt to the surface shape of the first shell and the second shell, thereby improving the sealing effect of the sealing member on the monitoring device.

[0017] According to the present disclosure, a monitoring device with good sealing performance can be provided. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] Hereinafter, the monitoring device involved in the present disclosure will be described in detail with reference to the accompanying drawings.

[0033] Figure 1 is a diagram showing an application scenario of the monitoring device 1 involved in the example of the present disclosure.

[0034] See also Figure 1The present disclosure relates to a monitoring device 1, which is a monitoring device 1 for obtaining physiological parameter information of a host. In some examples, the monitoring device 1 can be applied to the surface of the host's skin. Thus, the host's physiological information can be obtained. In some examples, the monitoring device 1 can generate information about a specific analyte in the body fluid based on the host's body fluid. For example, the monitoring device 1 can react with an analyte in the body fluid and generate information about the analyte.

[0038] Figure 2 Schematic diagram showing the overall assembly of the monitoring device 1 involved in the example of the present disclosure. Figure 3 is an exploded schematic diagram showing a monitoring device 1 according to an example of the present disclosure. Figure 4 1 is a schematic diagram showing the first perspective structure of the first shell 10 involved in the example of the present disclosure. Figure 5 2 is a schematic diagram showing the structure of the first shell 10 involved in the example of the present disclosure from a second viewing angle.

[0039] In some examples, the monitoring device 1 may include a first housing 10 (see Figure 3 ).

[0040] In some examples, the first housing 10 may be provided with a sensor 50 for acquiring physiological information of the host (see Figure 3 ). In some examples, the sensor 50 can be detachably mounted on the first housing 10. In some examples, the sensor 50 can be at least partially placed under the host's skin. Thus, the host's physiological information can be obtained through the sensor 50. In some examples, the first housing 10 and the second housing 20 can be mounted along the mounting direction (refer to Figure 3 In some examples, reference Figure 3 The direction of disassembly can be D2 direction (ie, the opposite direction of D1 direction).

[0041] Figure 6 2 is a schematic diagram showing the structure of the second housing 20 involved in the example of the present disclosure.

[0042] In some examples, the monitoring device 1 may include a second housing 20 (see Figure 3 ). In some examples, the second housing 20 may be provided with electronic devices.

[0043] In some examples, the monitoring device 1 may include a snap-fit ​​portion 30 (see Figure 3 ). In some examples, the first housing 10 and the second housing 20 can be detachably assembled through the engaging portion 30. In some examples, the sensor 50 can be electrically connected to the electronic device when the first housing 10 and the second housing 20 are assembled. Thus, the physiological parameter information of the host can be obtained.

[0044] In some examples, the snap-fit ​​portion 30 may include a first engagement feature 31 and a second engagement feature 32 (see Figure 3 In some examples, the first engagement feature 31 may have a concave structure or a convex structure. In some examples, the second engagement feature 32 may have a concave structure or a convex structure corresponding to the first engagement feature 31.

[0045] In some examples, the first engagement feature 31 may be provided on the first shell 10. In some examples, the second engagement feature 32 may be provided on the second shell 20. In other words, when a recessed structure is provided at the first position in the first shell 10, a convex structure cooperating with the recessed structure may be provided at a position of the second shell 20 that is opposite to the first position in the first shell 10 during assembly, and the first position may be any position in the first shell 10; the same is true when a convex structure is provided at the first position in the first shell 10, which will not be described in detail. In this case, the first shell 10 and the second shell 20 can be assembled. In some examples, the recessed structure may be a groove or a through hole. In some examples, the convex structure may be a convexity.

[0046] In some examples, there may be multiple engaging portions 30. In this case, by providing multiple engaging portions 30, the assembly stability of the first shell 10 and the second shell 20 can be improved, which is beneficial to reducing the assembly gap between the first shell 10 and the second shell 20.

[0047] In some examples, the multiple snap-fitting parts 30 may be distributed at both ends and both sides of the central axis of the monitoring device 1. In other words, the multiple snap-fitting parts 30 are distributed along the central axis of the monitoring device 1 and along the direction perpendicular to the central axis of the monitoring device 1. There are two snap-fitting parts 30 distributed along the central axis of the monitoring device 1 and they are distributed at the edge or end of the monitoring device 1. In this case, the multiple snap-fitting parts 30 are arranged at both ends and both sides of the central axis of the monitoring device 1. The multiple snap-fitting parts 30 can provide snap-fitting force for the combination of the two shells from multiple directions, which is conducive to further improving the sealing of the monitoring device 1.

[0048] In some examples, the shape of the first shell 10 and the second shell 20 after being assembled can be a cylinder, an elliptical cylinder, a rectangular parallelepiped, etc.

[0049] In some examples, the central axis of the monitoring device 1 may be an axis of symmetry of the first shell 10 or the second shell 20 .

[0050] In some examples, the shape of the first housing 10 and the second housing 20 after assembly may be a cuboid, and the central axis may be a symmetry axis parallel to the long side of the cuboid (see Figure 5 CA in the figure) or the axis of symmetry parallel to the short side of the cuboid (ref. Figure 5 EF in the figure). In some examples, the shape of the first shell 10 and the second shell 20 after assembly can be a cylinder, and the central axis of the monitoring device 1 can be any diameter of a circle. In some examples, the shape of the first shell 10 and the second shell 20 after assembly can be an elliptical cylinder, and the central axis of the monitoring device 1 can be the major axis or the minor axis of the ellipse.

[0051] In some examples, the number of the engaging portions 30 may be at least four and surround the outer circumference of the first shell 10 and the second shell 20. In some examples, the plurality of engaging portions 30 may be roughly uniformly arranged around the outer circumference of the first shell 10 and the second shell 20. For example, when the shape of the first shell 10 and the second shell 20 after assembly is a cylinder, the corresponding central angles between two adjacent engaging portions 30 are equal or the arc lengths between two adjacent engaging portions 30 are equal; when the shape of the first shell 10 and the second shell 20 after assembly is a cuboid, at least one engaging portion 30 is provided on each long side and each short side. In this case, the plurality of engaging portions 30 are uniformly distributed on the outer circumference of the first shell 10 and the second shell 20, so that the force borne by each engaging portion 30 is relatively uniform, the occurrence of damage to a certain engaging portion 30 due to excessive force borne can be reduced, and the assembly stability of the first shell 10 and the second shell 20 can be improved.

[0052] In some examples, at least one of the plurality of engaging portions 30 may be a primary engaging portion. In some examples, the first engaging feature 31 of the primary engaging portion may be configured to be deflectable.

[0053] In some examples, the main engaging portion may include a deflectable recessed structure or a protruding structure, thereby facilitating the assembly of the first housing 10 and the second housing 20 .

[0054] In some examples, the deflectable recessed structure or the protruding structure may be deflectable relative to the central axis of the first shell 10 or the second shell 20. In some examples, the deflectable recessed structure or the protruding structure may be deflected relative to the central axis of the first shell 10 or the second shell 20 in a direction away from the central axis. In this case, it is possible to facilitate the engagement and cooperation of the deflectable recessed structure and the protruding structure when the first shell 10 and the second shell 20 are assembled, thereby improving the convenience of assembly.

[0055] In some examples, the deflectable first engagement feature 31 may include a locked state and an unlocked state. In the present disclosure, the locked state may refer to a state in which the first housing 10 and the second housing 20 are in a relatively static state under the action of the engaging portion 30, wherein when the deflectable first engagement feature 31 in the main engaging portion is deflected outward, the main body of the first housing 10 and the second housing 20 still remain in a relatively static state, and the deflectable first engagement feature 31 is in a locked state. In the present disclosure, the unlocked state may refer to a state in which the first housing 10 and the second housing 20 are released from engagement, the main body of the first housing 10 and the second housing 20 move relative to each other or are separated from each other.

[0056] In some examples, when the first housing 10 is assembled to the second housing 20, the deflectable first engagement feature 31 may be in a locked state, and under the action of an external force, the deflectable first engagement feature 31 is deflected and transformed into an unlocked state to release the second housing 20. In this case, the deflectable first engagement feature 31 can be deflected when subjected to an external force, which can facilitate switching between the locked state and the unlocked state, thereby facilitating the disassembly and assembly of the first housing 10 and the second housing 20.

[0057] Fig. 7A 1 is a schematic diagram showing that the second engagement feature 32 according to the example of the present disclosure abuts against the deflectable first engagement feature 31 . Figure 7B is a schematic diagram showing that the deflectable first engagement feature 31 according to the example of the present disclosure is deflected outwardly. Figure 7C 2 is a schematic diagram showing that the deflectable first engagement feature 31 according to the example of the present disclosure is in a locked state.

[0058] In some examples, the second housing 20 can move toward the first housing 10 along the assembly direction (i.e., direction D1), and when the second engagement feature 32 in the main engaging portion abuts against the deflectable first engagement feature 31, the force applied by the second engagement feature 32 to the deflectable first engagement feature 31 can cause the deflectable first engagement feature 31 to deflect outward (refer to Figure 7B In some examples, when the second engagement feature 32 is fully accommodated in the recessed structure of the main engaging portion, the deflectable first engagement feature 31 can be deflected in the opposite direction of the outward deflection (refer to Figure 7B Thus, the first housing 10 and the second housing 20 can be assembled by snapping.

[0059] In some examples, when the first housing 10 and the second housing 20 are in a locked state, the first deflectable engagement feature 31 in the main engaging portion can be deflected outward by a force, and the second engagement feature 32 in the recessed structure of the main engaging portion can move in the direction of disassembly (i.e., direction D2), and when the second engagement feature 32 just breaks away from the contact state with the first deflectable engagement feature 31, the first deflectable engagement feature 31 can be changed from the locked state to the unlocked state. In this way, the first housing 10 and the second housing 20 can be disassembled.

[0060] In some examples, the second engagement feature 32 of the primary engaging portion may have a guide surface 321 (see Figure 3 ). In some examples, during the assembly of the first housing 10 and the second housing 20, the guide surface 321 may contact the deflectable first engagement feature 31 and guide the deflectable first engagement feature 31 to turn to the unlocked state. In this case, the assembly of the first housing 10 and the second housing 20 can be facilitated by the cooperation between the guide surface 321 and the deflectable first engagement feature 31.

[0061] In some examples, the guide surface 321 may be an inclined plane or a curved surface. In this case, the relative sliding between the deflectable first engagement feature 31 and the second engagement feature 32 can be facilitated, and the assembly process of the first shell 10 and the second shell 20 can be made more labor-saving and convenient (for example, the first shell 10 and the second shell 20 can be assembled by only one-handed operation).

[0062] In some examples, during the assembly process of the first housing 10 and the second housing 20, the surface where the deflectable first engagement feature 31 contacts the guide surface 321 may be an inclined surface or a curved surface. In this case, the guiding effect of the guide surface 321 when the deflectable first engagement feature 31 is deflected can be further improved, so that the deflectable first engagement feature 31 is easier to deflect. In addition, since the second housing 20 can be recycled and reused, setting the surface where the deflectable first engagement feature 31 contacts the guide surface 321 during the assembly process as an inclined surface or a curved surface can reduce the wear on the second engagement feature 32, thereby facilitating the maintenance of the service life of the second housing 20.

[0063] In some examples, the deflectable first engagement feature 31 may have a pressing portion 311 extending outwardly along the central axis (see Figure 3 In this case, the pressing portion 311 can increase the force application space when the host applies force to the deflectable first engagement feature 31. When it is necessary to apply force to the deflectable first engagement feature 31 to turn it into an unlocked state, the deflectable first engagement feature 31 can be deflected by applying force to the pressing portion 311, thereby improving the convenience of the host in disassembling and assembling the monitoring device 1.

[0064] In some examples, the first housing 10 may include a first substrate 11 (see Figure 4 In some examples, an extension portion 12 extending in a direction having a predetermined angle with respect to the first substrate 11 may be disposed around the edge of the first substrate 11 (see Figure 4 In some examples, the extension portion 12 may extend in the opposite direction (i.e., direction D2) to the assembly direction of the first shell 10 and the second shell 20. In this case, the extension portion 12 enables the first shell 10 to surround the second shell 20 during assembly, thereby improving the sealing between the first shell 10 and the second shell 20.

[0065] In some examples, the predetermined angle may be an angle between the first substrate 11 and the extension portion 12. In some examples, preferably, the predetermined angle may be 90 degrees. Thus, providing the extension portion 12 is conducive to improving the assembly sealing of the first shell 10 and the second shell 20.

[0066] In some examples, the extension 12 may include a first portion 121 (see Figure 4 ) and Section 122 (see Figure 4). In some examples, the displaceable first engagement feature 31 may be disposed on the first portion 121. In some examples, there may be a gap between the first portion 121 and the second portion 122. In this case, since the displaceable first engagement feature 31 needs to be deflected outward to a certain extent in order to provide a moving space for the second engagement feature 32 during the process of the displaceable first engagement feature 31 being displaced by an external force, the displaceable first engagement feature 31 needs to be deflected outward to a certain extent in order to provide a moving space for the second engagement feature 32. Therefore, disposing the first engagement feature 31 on the first portion 121 can not affect the wrapping of the second portion 122 on the second shell 20 (i.e., it does not affect the sealing between the first shell 10 and the second shell 20), and the gap can provide convenience for the displaceable first engagement feature 31 when it is displaced.

[0067] In some examples, the deflectable first engagement feature 31 may be deformable relative to the central axis of the first housing 10 or the second housing 20. In some examples, the deflectable first engagement feature 31 may be made of a plastic material. In this case, the possibility of the deflectable first engagement feature 31 breaking when it is bent or deformed by an external force can be reduced, thereby improving the assembly stability of the first housing 10 and the second housing 20.

[0068] In some examples, the second housing 20 may include a second substrate 21 (see Figure 6 ). In some examples, the second substrate 21 may be provided with electronic devices. In some examples, a first extension portion 22 extending in a direction having a first predetermined angle with the second substrate 21 may be provided around the edge of the second substrate 21. In some examples, the first extension portion 22 may extend in the assembly direction of the second shell 20 and the first shell 10 (i.e., the D1 direction). In this case, the first extension portion 22 enables the second shell 20 to wrap around the first shell 10 during assembly, thereby improving the sealing between the first shell 10 and the second shell 20.

[0069] In some examples, the first predetermined angle may be an angle formed by the second substrate 21 and the first extension portion 22. In some examples, preferably, the first predetermined angle may be 90 degrees. Thus, providing the first extension portion 22 is conducive to improving the assembly sealing of the first shell 10 and the second shell 20.

[0070] In some examples, at least one of the plurality of engaging portions 30 may be a secondary engaging portion. In some examples, the secondary engaging portion may be disposed at an end opposite to the primary engaging portion. In some examples, the first engaging feature 31 of the secondary engaging portion may be located at the second portion 122. In some examples, the first engaging feature 31 of the secondary engaging portion may be a through hole or a groove that passes through the second portion 122. In some examples, preferably, the first engaging feature 31 of the secondary engaging portion may be a through hole that passes through the second portion 122. Thus, the assembly stability of the first housing 10 and the second housing 20 can be improved.

[0071] In some examples, the extension 12 may protrude a predetermined height in a direction opposite to the assembly direction (i.e., direction D2) at a through hole. It should be understood that since the second shell 20 needs to be assembled with the first shell 10, the second shell 20 may be recessed in a direction opposite to the assembly direction (i.e., direction D2) at a corresponding position to a predetermined depth consistent with the predetermined height. In this case, the strength of the extension 12 at the through hole can be increased, thereby improving the assembly stability of the first shell 10 and the second shell 20.

[0072] In some examples, when the first housing 10 is assembled to the second housing 20, the second engagement feature 32 in the secondary engaging portion can engage with the first engagement feature 31 and protrude from the second portion 122. In this case, when the first housing 10 is assembled to the second housing 20, the second engagement feature 32 in the secondary engaging portion protrudes from the second portion 122 (i.e., the second engagement feature 32 protrudes from the through hole), so that the secondary engaging portion can provide a stronger engagement strength, which is beneficial to improving the assembly stability of the first housing 10 and the second housing 20.

[0073] In some examples, the concave structure in the secondary engaging portion may be a rectangular parallelepiped groove or through hole. In some examples, the convex structure in the secondary engaging portion may be a rectangular parallelepiped convexity.

[0074] In some examples, the engaging parts 30 located on both sides of the central axis of the monitoring device 1 may be side engaging parts. In some examples, the other engaging parts 30 distinguished from the main engaging parts and the auxiliary engaging parts in the plurality of engaging parts 30 may be side engaging parts. In some examples, the length and depth of the first engaging feature 31 and the second engaging feature 32 in the side engaging parts may be smaller than the length and depth of the first engaging feature 31 and the second engaging feature 32 in the engaging parts 30 located at both ends of the central axis of the monitoring device 1. In this case, the locking force provided by the side locking portion during assembly is smaller than the locking force provided by the main locking portion and the auxiliary locking portion respectively during assembly, thereby reducing the possibility of the first shell 10 and the second shell 20 being inconvenient to disassemble due to the excessive locking force applied to the monitoring device 1 in the direction of the central axis and in the direction perpendicular to the central axis; that is, if the monitoring device 1 is subjected to large locking forces in the direction of the central axis and in the direction perpendicular to the central axis, it is necessary to apply a certain force to all the locking portions 30 in the direction of the central axis and in the direction perpendicular to the central axis at the same time during disassembly to release the locking state. In the present disclosure, by providing the side locking portion, the force required in the direction perpendicular to the central axis can be reduced, thereby facilitating the disassembly of the two shells.

[0075] In some examples, the number of the side engaging parts can be multiple. In some examples, the multiple side engaging parts can be symmetrically distributed about the central axis of the monitoring device 1. Thus, the connection stability of the first shell 10 and the second shell 20 can be improved. In some examples, the multiple side engaging parts can be misaligned in a direction orthogonal to the central axis of the monitoring device 1. Thus, the risk of damaging the side engaging parts due to stress concentration can be reduced.

[0076] Figure 8 Schematic diagram showing the structure of the seal 40 involved in the example of the present disclosure.

[0077] In some examples, the monitoring device 1 may include a seal 40 (see Figure 8 ).

[0078] In some examples, when the first shell 10 and the second shell 20 are assembled, the seal 40 can be located between the first shell 10 and the second shell 20. In some examples, the seal 40 can be located between the first shell 10 and the second shell 20 and squeezed. In this case, by providing the seal 40 between the first shell 10 and the second shell 20 and squeezing the seal 40 when the first shell 10 and the second shell 20 are in the assembled state, it can be beneficial for the seal 40 to be in close contact with the first shell 10 and the second shell 20, thereby improving the sealing of the monitoring device 1, thereby reducing the possibility of the internal components of the monitoring device 1 being disturbed by the external environment (for example, reducing the possibility of short circuiting of electronic devices or reduced sensitivity of the sensor 50 caused by wearing the monitoring device 1 on rainy days or in a shower), thereby facilitating the normal operation and service life of the monitoring device 1. In addition, multiple snap-fitting portions 30 are arranged at both ends and both sides of the central axis of the monitoring device 1. The multiple snap-fitting portions 30 can provide snap-fitting force for the combination of the two shells from multiple directions, so that multiple positions of the seal 40 can be subjected to a strong extrusion force and in close contact with the two shells, which is beneficial to further improve the sealing performance of the monitoring device 1.

[0079] In some examples, the electronic device may include an electrical connection portion electrically connected to the sensor 50. In some examples, the seal 40 may be disposed on the second housing 20 and wrap the electronic device in a manner that the electrical connection portion is exposed. In this case, the sealing performance of the seal 40 on the electronic device can be improved, and when the first housing 10 and the second housing 20 are assembled, the electronic device can be electrically connected to the sensor 50 through the exposed electrical connection portion.

[0080] Fig. 9 1 is a schematic diagram showing the assembly of the seal 40 and the second housing 20 according to the example of the present disclosure.

[0081] In some examples, the seal 40 may be disposed on the second housing 20. In some examples, the seal 40 may protrude from the second housing 20 toward the assembly direction of the second housing 20 and the first housing 10. In this case, the seal 40 protruding from the second housing 20 is conducive to close contact between the seal 40 and the second housing 20 during assembly.

[0082] In some examples, the seal 40 may be elastic. In some examples, when the first shell 10 and the second shell 20 are assembled, the seal 40 may be deformed by the extrusion of the first shell 10 and the second shell 20. In this case, when the first shell 10 and the second shell 20 are assembled through the engaging portion 30, the seal 40 is deformed by the extrusion of the first shell 10 and the second shell 20, so that the seal 40 can better adapt to the surface shape of the first shell 10 and the second shell 20, thereby improving the sealing effect of the seal 40 on the monitoring device 1.

[0083] In some examples, the amount of deformation of the seal 40 after being squeezed may be 0.1 mm to 1.5 mm.

[0084] In some examples, the seal 40 may be made of a polymer material. In some examples, the seal 40 may be made of silicone rubber with a Shore A hardness of 20 to 60 degrees. Thus, the sealing performance of the monitoring device 1 can be improved.

[0085] In some examples, the seal 40 may be detachably assembled with the first housing 10 or the second housing 20 .

[0086] In some examples, the seal 40 can be assembled with the first housing 10 first, and the second housing 20 and the first housing 10 are then assembled through the snap-fit ​​portion 30. In this case, the sealing effect of the seal 40 on the sensor 50 can be improved, thereby reducing the risk of sensor 50 malfunctioning due to pollutants in the external environment. In some examples, preferably, the seal 40 can be assembled with the second housing 20 first, and the first housing 10 and the second housing 20 are then assembled through the snap-fit ​​portion 30. In this case, the sealing effect of the seal 40 on the electronic device can be improved.

[0087] In some examples, the seal 40 may be fixedly disposed on the first housing 10 or the second housing 20. In some examples, preferably, the seal 40 may be fixedly disposed on the second housing 20. In this case, the seal 40 can seal the electronic device, thereby reducing the damage to the electronic device caused by pollutants in the external environment and improving the reliability of the electronic device.

[0088] In some examples, the seal 40 may be disposed around the outer circumference of the first housing 10 or the second housing 20. In this case, when the first housing 10 and the second housing 20 are assembled, the seal 40 can be deformed, so that the first housing 10 and the second housing 20 are tightly assembled. For example, the seal 40 may be an annular sealing ring.

[0089] In some examples, the area between the first shell 10 and the second shell 20 after assembly may be referred to as an accommodation space. In some examples, the height of the outer contour of the seal 40 may be not less than the height of the accommodation space. In some examples, when the first shell 10 and the second shell 20 are assembled, the seal 40 is deformed by the extrusion of the first shell 10 and the second shell 20. In this case, when the first shell 10 and the second shell 20 are assembled, the seal 40 located between the first shell 10 and the second shell 20 is deformed by the extrusion, so that the seal 40 is more closely fitted to the surface shape of the first shell 10 and the second shell 20, thereby improving the sealing performance of the monitoring device 1.

[0090] In some examples, the seal 40 may have the same shape as the accommodating space. In this case, the sealing effect of the seal 40 on the monitoring device 1 can be improved. For example, the shape of the seal 40 may be a cuboid, a cylinder, an elliptical cylinder, etc.

[0091] In some examples, the first housing 10 may be provided with a sensor seat 13 (see Figure 4 In some examples, the second housing 20 may be provided with a battery for providing energy to the electronic device, and a battery compartment for accommodating the battery. In some examples, the seal 40 may be provided with a first accommodating groove 41 for accommodating the sensor seat 13 (see Figure 8 ) and a second receiving slot 42 for receiving the battery compartment (see Figure 8 ). This can help seal the sensor seat 13 and the battery compartment, and can reduce the impact of pollutants in the external environment on the performance of the sensor 50.

[0092] In the present disclosure, a monitoring device 1 with good sealing performance can be provided.

Those skilled in the art may modify and change the present disclosure as needed without departing from the essential spirit and scope of the present disclosure, and these modifications and changes all fall within the scope of the present disclosure.
