Description

Technical Field

[0001] This invention relates to the field of vital sign detection technology, and specifically to a vital sign detection device. Background Technology

[0002] With socio-economic development and improved living standards, people are paying increasing attention to their health, leading to a large number of vulnerable individuals requiring care and monitoring. The arrival of an aging society has resulted in a rapid increase in the elderly population, with the phenomena of advanced age and empty-nest living becoming increasingly prominent. To effectively improve the health of elderly people living alone, allowing family members to work with peace of mind while better monitoring their health, and to promptly identify their location and seek medical assistance in case of emergencies, millimeter-wave radar is typically used to detect vital signs in real time within a room.

[0003] When installing millimeter-wave radar, the angle of the radar needs to be adjusted to cover a wider area. For example, patent CN217213457U discloses a contactless smart home device, comprising: a housing, a main control board, a universal joint structure, and a base. The main control board is housed within the housing, which is connected to the base via the universal joint structure. The main control board includes a power circuit, a 485 circuit, a main control unit, a wireless communication unit, a millimeter-wave radar unit, an indicator light circuit, and a button circuit. The power circuit is connected to the 485 circuit, the main control unit, the wireless communication unit, and the millimeter-wave radar unit. The main control unit is connected to the 485 circuit, the wireless communication unit, the millimeter-wave radar unit, the indicator light circuit, and the button circuit. This device can dynamically detect human vital signs.

[0004] However, the installation method using universal joint structures such as ball joints can easily cause the direction of the millimeter-wave radar to change over a long period of time, thus changing the coverage area of ​​the millimeter-wave radar and making it easy to create blind spots. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the technical problem to be solved by the present invention is that: the installation method of using universal joint structure such as ball joint can easily cause the direction of millimeter-wave radar to change after a long period of accumulation, which will change the coverage range of millimeter-wave radar and thus easily create blind spots.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a vital signs detection device, comprising:

[0007] The probe itself can detect a person's vital signs;

[0008] The base can be fixedly installed on the wall;

[0009] The adjustment mechanism includes an adjustment plate, a first rotating shaft, and a second rotating shaft;

[0010] One end of the adjusting plate is hinged to the base via a first rotating shaft, and the first rotating shaft is fixedly connected to the base; the other end of the adjusting plate is hinged to the probe body via a second rotating shaft, the second rotating shaft is fixedly connected to the probe body, and the first rotating shaft and the second rotating shaft are arranged perpendicular to each other; and

[0011] The limiting mechanism can simultaneously restrict the rotation of the first and second rotating shafts on the adjusting plate.

[0012] In this invention, the coverage area of ​​the probe head body is adjusted by adjusting the traffic flow between the adjustment plate and the base and the angle between the adjustment plate and the probe head body. Then, the limiting mechanism is controlled to restrict the rotation of the first and second rotating shafts. This restricts the traffic flow between the adjustment plate and the base and the angle between the adjustment plate and the probe head body, thereby fixing the probe head body and effectively preventing the probe head body from changing its coverage area and creating blind spots.

[0013] Preferably, the limiting mechanism includes gears, sliders, limiting clips, and a pushing component; the adjusting plate has a sliding groove, and gears are coaxially fixedly mounted on the first and second rotating shafts, with the two gears located within the sliding groove; each slider corresponds to a gear, and the slider is slidably mounted within the sliding groove; a limiting clip is fixedly mounted on the end of each slider near the gear, and the limiting clip engages with the tooth groove of the corresponding gear; the pushing component can push the two sliders closer to or away from the corresponding gear. The pushing component pushes the slider closer to the corresponding gear, causing the limiting clip on the slider to engage with the tooth groove of the gear, thereby limiting the rotation of the first and second rotating shafts through the gears; achieving simultaneous fixation of the probe body at two angles.

[0014] Preferably, the pushing assembly includes a hinge plate, a pushing block, and a threaded rod. Hinges are respectively provided on both sides of the pushing block, with each hinge plate corresponding to a slider. One end of each hinge plate is hinged to the pushing block, and the other end is hinged to the slider. The threaded rod is rotatably mounted on the pushing block, and the threaded rod is perpendicular to the axis of the hinge point on the hinge plate. A threaded groove is provided on the adjusting plate, and the threaded rod engages with the threaded groove. Movement of the threaded rod drives movement of the pushing block, which in turn drives the slider to slide via the hinge plates, thereby simultaneously causing the two sliders to slide in opposite directions.

[0015] Preferably, two pushing components are provided, symmetrically arranged, and each component further includes a rectangular insert rod. The rectangular insert rod is coaxially and slidably inserted into the two threaded rods, and the threads of the two threaded rods have opposite directions. The two symmetrically arranged pushing components interlock with each other, effectively preventing spontaneous rotation of the threaded rods and thus avoiding changes in the coverage area of ​​the probe body.

[0016] Preferably, the rectangular insert is vertically arranged, and a limiting plate is fixedly installed on the rectangular insert. A limiting groove is formed on the adjusting plate, and the limiting plate is slidably installed in the limiting groove. The vertically arranged rectangular insert can move downward by gravity without the application of external force and slide out of the threaded rod; by the limiting plate sliding in the limiting groove, the rectangular insert can be effectively prevented from falling off and being lost.

[0017] Preferably, the first rotating shaft is fixedly connected to the base via a mounting seat; the mounting seat includes a first lug and a mounting plate; two first lugs are fixedly installed at both ends of the first rotating shaft, and the two first lugs are fixedly installed on the mounting plate, which is detachably connected to the base. This detachable connection between the mounting seat and the base allows the adjustment mechanism to be easily removed, facilitating maintenance and replacement.

[0018] Preferably, the second rotating shaft is fixedly connected to the probe body via a connecting seat; the connecting seat includes a second lug and a connecting plate; the two ends of the second rotating shaft are respectively fixedly installed with second lugs, the two second lugs are fixedly installed on the connecting plate, and the probe body is installed on the connecting plate. The connecting seat connects the second rotating shaft and the probe body, allowing the probe body to rotate with the rotation of the second rotating shaft.

[0019] Preferably, a knob is installed on the rectangular insertion rod. The knob increases the contact area, making it easier to rotate the rectangular insertion rod.

[0020] Compared with the prior art, the present invention has at least the following advantages:

[0021] 1. Effectively prevents blind spots caused by changes in the coverage area of ​​the probe body. In this invention, the coverage area of ​​the probe body is adjusted by regulating the flow between the adjusting plate and the base and the angle between the adjusting plate and the probe body. Then, the limiting mechanism is controlled to restrict the rotation of the first and second rotating shafts. This limits the flow between the adjusting plate and the base and the angle between the adjusting plate and the probe body, thus fixing the probe body and effectively preventing blind spots caused by changes in the coverage area of ​​the probe body.

[0022] 2. To reduce installation time waste, the first and second rotating shafts are simultaneously restricted by a limiting mechanism, thereby simultaneously restricting the hinge points at the probe body and the base. This eliminates the need to restrict the hinge points at the probe body and the base individually after the angle of the probe body is adjusted, thus significantly shortening the installation time and improving the efficiency of probe body installation.

[0023] 3. Two symmetrically arranged push components are set up to interlock the two threaded rods, which can effectively prevent the threaded rods from rotating spontaneously under the action of external force, thus changing the coverage area of ​​the probe body. Attached Figure Description

Detailed Implementation

[0031] The embodiments of the technical solution of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the technical solution of the present invention and are therefore intended to limit the scope of protection of the present invention.

[0032] In this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0033] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0034] See Figures 1-2 The present invention provides an embodiment of a vital signs detection device, comprising: a probe body, a base 1, an adjustment mechanism 2, and a limiting mechanism 3; the probe body can detect human vital signs; the base 1 can be fixedly installed on a wall; the adjustment mechanism 2 includes an adjustment plate 21, a first rotating shaft 22, and a second rotating shaft 23; one end of the adjustment plate 21 is hinged to the base 1 via the first rotating shaft 22, and the first rotating shaft 22 is fixedly connected to the base 1; the other end of the adjustment plate 21 is hinged to the probe body via the second rotating shaft 23, and the second rotating shaft 23 is fixedly connected to the probe body, and the first rotating shaft 22 and the second rotating shaft 23 are arranged perpendicularly to each other; the limiting mechanism 3 can simultaneously restrict the rotation of the first rotating shaft 22 and the second rotating shaft 23 on the adjustment plate 21.

[0035] In practice, the base 1 is fixedly installed on the wall. Then, the coverage area of ​​the probe body is adjusted by adjusting the traffic between the adjustment plate 21 and the base 1 and the angle between the adjustment plate 21 and the probe body. Then, the action of the limiting mechanism 3 is controlled. The limiting mechanism 3 restricts the rotation of the first rotating shaft 22 and the second rotating shaft 23. In this way, the traffic between the adjustment plate 21 and the base 1 and the angle between the adjustment plate 21 and the probe body are limited, thereby fixing the probe body and effectively preventing the blind spots from changing the coverage area of ​​the probe body.

[0036] Furthermore, existing technologies typically restrict the hinge points one by one. This method of restriction means that after the first hinge point is restricted, when restricting the second hinge point, the first hinge point needs to be restricted again because it is not properly restricted, thus wasting a lot of time in installing the probe body. In order to reduce the waste of installation time, the limiting mechanism 3 simultaneously restricts the rotation of the first rotating shaft 22 and the second rotating shaft 23, thereby restricting the hinge points at both the probe body and the base 1 at the same time. After the angle of the probe body is adjusted, it is not necessary to restrict the hinge points at both the probe body and the base 1 one by one, thus shortening the installation time significantly and improving the efficiency of probe body installation.

[0037] See Figures 1-4 In other embodiments, the limiting mechanism 3 includes a gear 31, a slider 32, a limiting clip 33, and a pushing component. A groove 211 is provided on the adjusting plate 21. Gears 31 are coaxially fixedly mounted on the first rotating shaft 22 and the second rotating shaft 23, with both gears 31 located within the groove 211. Slider 32 corresponds one-to-one with each gear 31, and the slider 32 is slidably mounted within the groove 211. A limiting clip 33 is fixedly mounted on the end of each slider 32 near the gear 31, and the limiting clip 33 engages with the tooth groove of the corresponding gear 31. The pushing component can push the two sliders 32 closer to or further away from the corresponding gear 31. Specifically, after the angle of the probe body is adjusted, the pushing component actuates, pushing the slider 32 closer to the corresponding gear 31, causing the limiting clip 33 on the slider 32 to engage with the tooth groove of the gear 31, thereby limiting the rotation of the first rotating shaft 22 and the second rotating shaft 23 through the gear 31; achieving simultaneous fixation of the probe body at two angles.

[0038] See Figures 1-4 In other embodiments, the pushing assembly includes a hinge plate 34, a pushing block 35, and a threaded rod 36. Hinges 34 are respectively provided on both sides of the pushing block 35, with each hinge plate 34 corresponding to a slider 32. One end of each hinge plate 34 is hinged to the pushing block 35, and the other end is hinged to the slider 32. The threaded rod 36 is rotatably mounted on the pushing block 35, and the threaded rod 36 is perpendicular to the axis of the hinge point on the hinge plate 34. A threaded groove 212 is provided on the adjusting plate 21, and the threaded rod 36 engages with the threaded groove 212. In specific implementation, rotating the threaded rod 36, with the engagement of the threaded groove 212, causes the threaded rod 36 to move, driving the pushing block 35 to move. The pushing block 35, through the hinge plate 34, drives the slider 32 to slide, thereby simultaneously driving the two sliders 32 to slide in opposite directions. The threaded connection also enables self-locking of the pushing block 35.

[0039] See Figures 1-4In other embodiments, two symmetrically arranged pushing components are provided, including a rectangular insert 37. The rectangular insert 37 is coaxially and slidably connected to two threaded rods 36, with the threads of the two threaded rods 36 having opposite directions. In specific implementations, the two symmetrically arranged pushing components ensure that when adjusting the sliding of the slider 32, both threaded rods 36 must be rotated simultaneously via the rectangular insert 37 to move the slider 32. When the rectangular insert 37 slides out of one of the threaded rods 36, the two threaded rods 36 interlock, effectively preventing spontaneous rotation of the threaded rods 36 and thus avoiding changes in the coverage area of ​​the probe body. Furthermore, a knob 39 is installed on the rectangular insert 37; the knob 39 increases the contact area, making it easier to rotate the rectangular insert 37.

[0040] See Figures 1-4 In other embodiments, the rectangular insert 37 is vertically arranged, and a limiting plate 38 is fixedly installed on the rectangular insert 37. A limiting groove 213 is formed on the adjusting plate 21, and the limiting plate 38 is slidably installed in the limiting groove 213. In specific implementation, the vertically arranged rectangular insert 37 can move downward by gravity without the application of external force and slide out of the threaded rod 36; the sliding of the limiting plate 38 in the limiting groove 213 can effectively prevent the rectangular insert 37 from falling off and being lost.

[0041] See Figure 1 and Figure 5 In other embodiments, the first rotating shaft 22 is fixedly connected to the base 1 via a mounting base 4; the mounting base 4 includes a first lug 41 and a mounting plate 42; two first lugs 41 are fixedly installed at both ends of the first rotating shaft 22, and the two first lugs 41 are fixedly installed on the mounting plate 42, which is detachably connected to the base 1. The detachable connection between the mounting base 4 and the base 1 allows for easy removal of the adjustment mechanism 2, facilitating maintenance and replacement; specifically, the mounting plate 42 and the base 1 can be detachably connected via bolts.

[0042] See Figure 1 In another embodiment, the second rotating shaft 23 is fixedly connected to the probe body via a connecting seat 5; the connecting seat 5 includes a second lug 51 and a connecting plate 52; the two ends of the second rotating shaft 23 are respectively fixedly mounted with second lugs 51, and the two second lugs 51 are fixedly mounted on the connecting plate 52, and the probe body is mounted on the connecting plate 52. The connecting seat 5 connects the second rotating shaft 23 and the probe body, so that the probe body can rotate with the rotation of the second rotating shaft 23.

[0043] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered within the scope of the claims and specification of the present invention.
