Description

Technical Field

[0001] This utility model relates to the field of intelligent monitoring equipment, specifically a sleep monitoring sensor. Background Technology

[0002] With the continuous improvement of people's living standards, the requirements for rest are also increasing, especially sleep quality, which is a crucial indicator. Sleep-related data includes not only sleep duration but also vital signs such as respiration, heart rate, snoring, and body movement, as well as sleep state. Current methods for monitoring this data typically use thin sleep monitoring sensors. These sensors are placed inside the mattress or between the mattress and the bed, incorporating pressure and weight sensors. Data is collected by the deformation caused by the user lying on the bed. However, this type of monitor has shortcomings: because these sleep detectors are thin products, current products on the market rely solely on the deformation of the mattress to generate pressure signals for the piezoelectric and weight sensors. This non-rebound structure, relying solely on deformation, results in inaccurate data collection of vital signs, particularly regarding vibrations and rolling movements. Therefore, there is an urgent need to develop a sleep monitoring sensor that can improve data collection accuracy without affecting the user's sleep experience. Summary of the Invention

[0003] The purpose of this invention is to provide a sleep monitoring sensor to solve the problems mentioned in the background art.

[0004] The technical solution of this utility model is as follows: A sleep monitoring sensor includes an upper cover, a lower cover, a PCBA, a pressure sensor, and an elastomer. The upper cover and the lower cover are fastened together to form a receiving space for accommodating the PCBA, the pressure sensor, and the elastomer. The lower cover has a PCBA receiving position for accommodating the PCBA, and the PCBA is disposed in the PCBA receiving position. The pressure sensor is disposed above the PCBA, and the elastomer is disposed between the pressure sensor and the PCBA. The pressure sensor is electrically connected to the PCBA. The lower cover has a surrounding edge, and the upper cover has a cover edge, which covers the outside of the surrounding edge. One of the surrounding edge and the cover edge has a groove, and the other has a hook that engages with the groove. The hook can slide up and down within the groove.

[0005] Preferably, several sets of guide connecting posts are evenly distributed in the middle of the upper cover and the middle of the lower cover. The upper cover guide posts are located on the upper cover, and the lower cover guide posts are located on the lower cover.

The rebound force is provided by an elastic body, and the rebound space is provided by the hook on the outer wall of the perimeter and the groove on the inner wall of the cover edge.

[0007] Preferably, the combination of the groove and the hook is in several groups, which are evenly distributed around the sleep monitoring sensor. The length of the groove is the height of the compression and rebound space between the upper cover and the lower cover. The groove is 4±0.5mm long and the overall thickness of the sleep monitoring sensor is 1±0.5cm.

[0008] Preferably, the elastomer is a rigid sponge.

The inner surface of the upper cover is provided with a pressure column corresponding to the inner E structure. When a person lies down, the upper cover is driven to descend, and the pressure column drives the inner E structure to realize the weighing operation of the load cell.

[0012] Preferably, the upper surface of the cover is curved with a higher center and lower sides, the middle of the cover is horizontal, and the sides are provided with inclined slopes, and a transition arc is provided between the upper surface of the cover and the edge of the cover.

Detailed Implementation

[0023] A sleep monitoring sensor includes an upper cover 1, a lower cover 6, a PCBA 4, a pressure sensor 2, and an elastomer 3. The upper cover 1 and the lower cover 6 are fastened together to form a receiving space for accommodating the PCBA 4, the pressure sensor 2, and the elastomer 3. The lower cover 6 has a PCBA receiving position 61 for accommodating the PCBA 4, and the PCBA 4 is disposed within the PCBA receiving position 61. The pressure sensor 2 is disposed above the PCBA 4, and the elastomer 3 is disposed between the pressure sensor 2 and the PCBA 4. Device 2 is electrically connected to PCBA4. The lower cover 6 has a surrounding edge 66, and the upper cover 1 has a cover edge 16, which covers the outside of the surrounding edge 66. A groove 8 is provided at one location of the surrounding edge 66 and the cover edge 16, and a hook 9 is provided at the other location to engage with the groove 8. The hook 9 can slide up and down within the groove 8. There is a compression and rebound space between the upper cover 1 and the lower cover 6. The rebound force is provided by the elastic body 3, and the rebound space is provided by the groove 8 on the outer wall of the surrounding edge 66 and the hook 9 on the inner wall of the cover edge 16. The rebound force enhances the ability of the pressure sensor 2 to detect slight vibrations.

[0024] In this embodiment, several sets of guide connecting posts are evenly distributed in the middle of the upper cover 1 and the middle of the lower cover 6. The upper cover guide post 13 is located on the upper cover 1, and the lower cover guide post 63 is located on the lower cover 6. The upper cover guide post 13 and the lower cover guide post 63 are adapted to each other, and the two can slide relative to each other. The guide posts are set to ensure that the upper cover 1 and the lower cover 6 do not slip or jam during compression and rebound.

[0025] In this embodiment, the outer wall of the perimeter 66 is provided with a groove 8, and the inner wall of the cover edge 16 is provided with a hook 9. The hook 9 engages with the groove 8 and can slide up and down in the groove 8. There is a compression and rebound space between the upper cover 1 and the lower cover 6. The rebound force is provided by the elastic body 3, and the rebound space is provided by the hook 9 on the outer wall of the perimeter 66 and the groove 8 on the inner wall of the cover edge 16.

[0026] In this embodiment, the structures of the groove 8 and the hook 9 can be interchanged, or other alternative technical structures can be used, such as setting limit position guards on the upper cover 1 and the lower cover 6, as long as the same technical structure can be achieved.

[0027] In this embodiment, the groove 8 and the hook 9 are combined in several groups and are evenly distributed around the sleep monitoring sensor. The length of the groove 8 is the height of the compression and rebound space between the upper cover 1 and the lower cover 6. The groove 8 is 4±0.5mm long and the overall thickness of the sleep monitoring sensor is 1±0.5cm.

[0028] In this embodiment, the elastomer 3 is a rigid sponge.

[0029] Since this utility model is placed under the mattress during actual use, and it is an ultra-thin sleep monitoring sensor, it cannot be equipped with ordinary elastic components, such as springs, because there is no place to put them. Therefore, hard sponge is used. Moreover, during actual use, this utility model only requires a rebound space of about 1-2mm. Therefore, hard sponge is used as the elastic body 3, which ensures both compression function and rebound force, so that the product will not fail to rebound after being compressed.

[0030] In this embodiment, the upper surface of the lower cover 6 is provided with a PCBA support assembly 67 to form a space for accommodating PCBA4 and to limit the outer periphery of PCBA4. The lower surface of the upper cover 1 is provided with a pressure sensor support assembly 15 to form a space for accommodating pressure sensor 2 and to limit the outer periphery of pressure sensor 2.

[0031] In this embodiment, a plurality of weighing sensors 5 are also provided in the accommodating space. The weighing sensors 5 are electrically connected to the PCBA4 and are located on the left and right sides of the pressure sensor 2.

[0032] In this embodiment, the weighing sensor 5 has a double-E structure, including an inner E structure 51 and an outer E structure 52. The inner E structure 51 and the outer E structure 52 are connected by a cantilever in the middle. The upper surface of the lower cover 6 is provided with a weighing sensor support assembly 68, which forms a space to accommodate the weighing sensor 5, supports the outer E structure 52 and limits its outer periphery, so that the inner E structure 51 is suspended above the lower cover 6. The inner surface of the upper cover 1 is provided with a pressure column 14 corresponding to the inner E structure 51. When a person lies down, the upper cover 1 is driven to descend, and the pressure column 14 drives the inner E structure 51 to realize the weighing operation of the weighing sensor 5.

[0033] In this embodiment, the upper surface of the cover 1 is curved, with a higher center and lower sides. The middle of the cover 1 is horizontal, and the two sides are provided with inclined slopes 11. A transition arc 12 is provided between the upper surface of the cover 1 and the cover edge 16. This structure is designed to make the outer perimeter of the entire product thinner and smoother, so that the user does not perceive it and achieves the purpose of imperceptible monitoring.

[0034] In this embodiment, a wire pressure plate 7 is also included. A cable management seat 62 is provided on the lower cover 6. The wire pressure plate 7 is adapted to the cable management seat 62, and a cable management groove is provided in the middle of the wire pressure plate 7 and the cable management seat 62. Since the product of this utility model is an ultra-thin sleep monitoring sensor, there must be some connecting wires connecting the PCBA4, pressure sensor 2, weighing sensor 5, and power supply device inside the device. These connecting wires will also interfere with the pressing and rebound of the upper cover 1. Therefore, it is necessary to eliminate the influence caused by them within the limited space. Therefore, the wire pressure plate 7 and the cable management seat 62 are set to organize and constrain the connecting wires to prevent them from affecting the pressing and rebound of the upper cover 1.

[0035] In this embodiment, a mounting base 65 is also included, and the mounting base 65 is provided with a mounting hole 64. The mounting hole 64 is an elongated slot hole, which is designed to facilitate the installation of this utility model.
