[0061] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments of the present application. The technical solutions among the embodiments can be combined with each other, but the combination of the technical solutions should be based on the realization of the technical solutions by the person skilled in the art. When the combination of the technical solutions is contradictory or unachievable, it should be considered that the combination of the technical solutions does not exist, and is not within the protection scope of the present application.

[0062] The power supply modes of the existing human body sensors include strong power supply, weak power supply and battery power supply. The human body sensors with strong power supply and weak power supply need to be connected to power lines, which limits the installation position and affects the installation flexibility and convenience. The human body sensor with battery power supply does not need to be connected to the power line and can be pasted at any position, so that the detection area is adjusted to be optimal. However, the battery life is generally only 1-2 years, and frequent replacement of the battery brings inconvenience to use.

[0063] In order to solve the problem of limited installation position or frequent replacement of the battery of the existing human body sensor, according to the first aspect of the present application, a human body detection device 100 is provided, please refer to Figures 1-29 The human body detection device 100 provided by the present application will be specifically explained. Specifically, as shown in Figures 1-6 The human body detection device 100 includes a cylindrical detection main body 1, an adjusting support 2 rotatably connected to the end of the detection main body 1, the detection main body 1 can rotate relative to the adjusting support 2 to adjust the detection direction, and a light energy power generation assembly 3 inserted into one end of the detection main body 1 connected to the adjusting support 2 and electrically connected to the detection main body 1 in the form of insertion. The cylindrical detection main body 1 can be a cylinder, a polygonal prism or a similar column. The detection main body 1 is internally provided with a detection module for detecting a human body, which can include an infrared pyroelectric detection module and / or a radar detection module. The light energy power generation assembly 3 can be understood as an external device with light energy power generation function, which can convert light energy into electrical energy.

[0064] The light energy power generation assembly 3 is directly inserted into the detection main body 1, which not only can supply power for the detection main body 1, but also can realize the suspension installation of the light energy power generation assembly 3 without the need to additionally set the installation structure, so that the structure is more simplified. The insertion installation mode is convenient for simple and rapid installation and disassembly of the light energy power generation assembly 3. The insertion mode can adopt a USB plug insertion (as shown in Figure 3 , or can adopt a DC power plug insertion (as shown in Figure 29 , or can adopt other insertion modes to realize electrical connection.

[0065] The light energy power generation assembly 3 provided by the embodiment of the present application mainly plays two roles:

[0066] 1. An energy storage capacitor 33 can be installed inside the solar power generation component 3 to store the electrical energy generated by the solar panel 31. When the power generation of the solar panel 31 is large enough and the capacity of the energy storage capacitor 33 is large enough, the power generation of the solar power generation component 3 can sustain the detection body 1 for 24 hours a day. At this time, the detection body 1 only needs the solar power generation component 3 for power supply and does not need a power cord or battery power supply, which solves the problem of limited installation location and frequent battery replacement of existing human body sensors.

[0067] 2. If the power output of the solar power generation component 3 is too small to maintain the continuous operation of the detection body 1, a button battery 15 can be installed inside the detection body 1. The solar power generation component 3 and the button battery 15 work together. When the solar power generation component 3 has sufficient power, it is used to supply power. When the power of the solar power generation component 3 is insufficient, it is switched to the button battery 15 for power supply. This greatly improves the battery life of the button battery 15 and solves the problems of limited installation location and frequent battery replacement of existing human body sensors.

[0068] In embodiments of the present invention, such as Figure 1 and Figure 2 As shown, the adjustment bracket 2 includes a first adjustment member 21 connected to the detection body 1 and a second adjustment member 22 connected to the edge of the first adjustment member 21. The second adjustment member 22 is used to connect to the mounting surface 200. The first adjustment member 21 and the second adjustment member 22 are in a first adjustment state. In the first adjustment state, the first adjustment member 21 is perpendicular to the second adjustment member 22, and the photovoltaic power generation component 3 is located in the right-angle space formed between the first adjustment member 21 and the second adjustment member 22. The mounting surface 200 can be understood as the surface of an object used to install the human body detection device 100, such as a wall, refrigerator door surface, cabinet door surface, etc. The second adjustment member 22 can be directly pasted to the mounting surface 200, or magnetically connected to the mounting surface 200, or a piece of iron is pasted on the mounting surface 200 and the second adjustment member 22 is magnetically connected to the piece of iron, or it can be installed on the mounting surface 200 in other ways.

[0069] The first adjustment state is a commonly used state in daily use. At this time, the first adjustment member 21 is perpendicular to the second adjustment member 22, and the axis of the detection body 1 is parallel to the mounting surface 200 (e.g., Figure 2 As shown in the figure, the right-angle space would become a wasted dead space in conventional design. However, in this embodiment of the invention, the photovoltaic power generation component 3 is placed in the right-angle space, which makes good use of this space and makes the whole product highly integrated and the structure more compact.

[0070] Further, the light energy power generation component 3 is located in the right angle space, which can avoid the light energy power generation component 3 from blocking the detection signal of the detection main body 1.

[0071] Further, as shown in Figure 1 and Figure 2 , the light energy power generation component 3 comprises a light energy receiving surface 311, the detection main body 1 is internally provided with an infrared pyroelectric module 111, a detection window 131 is opened on the side of the detection main body 1, a lens carrier 14 is installed on the detection window 131, the lens carrier 14 comprises a lens assembly 141, which is used for converging infrared light to the infrared pyroelectric module 111; wherein the detection window 131 and the light energy receiving surface 311 are towards the same side, and the light energy power generation component 3 rotates synchronously with the detection main body 1.

[0072] Generally, the area detected by the detection main body 1 is the area of human activity, and the area of human activity is usually the area with light source. The light energy receiving surface 311 and the detection window 131 are towards the same side, and the light energy power generation component 3 rotates synchronously with the detection main body 1, which can make the light energy receiving surface 311 towards the direction with light source, ensure the power generation efficiency of the light energy power generation component 3, and does not need to adjust the direction of the light energy receiving surface 311 separately, which is more convenient. In an embodiment, as shown in Figure 1 , the upper end of the light energy power generation component 3 is provided with a USB plug, the lower end of the detection main body 1 is opened with a USB jack, the light energy power generation component 3 is plugged into the USB jack through the USB plug, which realizes the electrical connection between the light energy power generation component 3 and the detection main body 1, and the light energy power generation component 3 rotates synchronously with the detection main body 1.

[0073] In other embodiments, as shown in Figure 29 , the light energy power generation component 3 can also not rotate synchronously with the detection main body 1, so that the detection direction and the light energy receiving direction can be adjusted separately, thereby making the light energy receiving surface 311 accurately towards the light source, further improving the power generation efficiency, and more accurately controlling the detection range. Specifically, as shown in Figure 29 , one end of the light energy power generation component 3 is provided with a DC power plug, one end of the detection main body 1 is opened with a DC power jack, the light energy power generation component 3 is plugged into the DC power jack through the DC power plug, which realizes the electrical connection between the light energy power generation component 3 and the detection main body 1. Since the DC power plug is cylindrical, the light energy power generation component 3 can rotate around the DC power plug after being plugged into the detection main body 1, which realizes the separate adjustment of the detection direction and the light energy receiving direction.

[0074] As shown in Figure 2As shown, when the detection main body 1 is in the first adjusting state, the straight angle space at the lower end of the detection main body 1 can be used to insert the light energy power generation assembly 3, at this time, the axial direction of the detection main body 1 is parallel to the wall surface, and thanks to the detection window 131 arranged on the side of the detection main body 1, the detection direction can be towards the side away from the wall surface, so as to avoid the detection signal being blocked by the wall.

[0075] The lens assembly 141 is composed of a plurality of lens units 1411, which can be small convex lenses or Fresnel lenses. The lens units 1411 have a condensing effect, which is used to condense the infrared light emitted by the human body on the infrared pyroelectric module 111, thereby improving the sensing sensitivity of the infrared pyroelectric module 111. The human body movement in the target area can condense the moving infrared light spot on the infrared pyroelectric module 111, so that the pins of the infrared pyroelectric module 111 generate a level change. The detection main body 1 can determine whether there is a human body in the target area according to the level change of the infrared pyroelectric module 111. Therefore, a large number of lens units 1411 can improve the infrared sensing sensitivity.

[0076] Further, as shown in the drawings, Figure 5 The detection main body 1 is configured in a similar cylindrical shape, which includes a cylindrical shell 13, the detection window 131 is arranged on the cylindrical shell 13, the detection window 131 occupies a circumferential angle range of the cylindrical shell 13 greater than 120°, the lens carrier 14 includes an arc-shaped sheet 142 and the lens assembly 141 arranged on the back of the arc-shaped sheet 142, and the arc-shaped sheet 142 is limited to the inside of the detection window 131. The similar cylindrical shape includes a cylindrical shape and a shape similar to the cylindrical shape. In an exemplary embodiment, as shown in the drawings, Figure 6 The detection main body 1 is configured as a prism with a 16-sided cross section.

[0077] The detection window 131 occupies a circumferential angle greater than 120°, so that the infrared detection range can cover a relatively wide fan-shaped area in the horizontal direction; and most of the radar waves emitted by the radar module 124 pass through the lens carrier 14, so that the detection performance of the radar module 124 is better. In an embodiment, as shown in the drawings, Figure 5 and Figure 2 The detection window 131 has a shape with narrow upper and lower ends and a wide middle part, and the middle part occupies a circumferential angle of 180°.

[0078] The arc-shaped sheet 142 is limited to the inside of the detection window 131, which ensures that the lens carrier 14 is stably fixed inside the cylindrical shell 13, and avoids the lens carrier 14 from being separated from the cylindrical shell 13.

[0079] The arch shape can be understood as a specific shape: an arch shape is formed by extending a circular arc or an arc-like curve in a direction perpendicular to the plane in which the curve lies, for example, cutting a cylindrical shape into two halves along the axial direction, one of the two halves is an arch shape. As shown in Figure 21 The lens carrier 14 is configured as an arch shape, which has the advantages of adapting to the shape of the detection window 131, the arch-shaped sheet 142 can be attached to the edges of the detection window 131, so that the detection window 131 is completely enclosed, and the arch-shaped sheet 142 is easy to manufacture.

[0080] In some embodiments, as shown in Figure 3 , Figure 4 and Figure 29 The light energy power generation assembly 3 includes a housing assembly 35, a plug-in part 34 arranged at one end of the housing assembly 35, and a light energy panel 31 arranged on one side of the housing assembly 35. The light energy power generation assembly 3 is plugged into the detection main body 1 through the plug-in part 34. The side of the housing assembly 35 away from the light energy panel 31 is configured as a shape with a thick middle and thin sides, so that the light energy power generation assembly 3 can be rotated by a specific angle. As shown in Figure 2 and Figure 4 The specific angle can be understood as the range of angles within which the light energy power generation assembly 3 can be rotated without interfering with other components. Since the light energy power generation assembly 3 is located in the right-angle space formed between the first adjusting part 21 and the second adjusting part 22, during horizontal rotation, the two sides of the light energy power generation assembly 3 will interfere with the second adjusting part 22 in the vertical state, which limits the rotation angle of the light energy power generation assembly 3. Therefore, the light energy power generation assembly 3 can only be rotated within the specific angle. Since the light energy power generation assembly 3 rotates synchronously with the detection main body 1, the rotation angle of the detection main body 1 is also limited.

[0081] Narrowing the width of the light energy power generation assembly can expand the specific angle, but the light energy power generation efficiency will be greatly reduced. In the embodiment of the present application, the shape of the housing assembly 35 is designed to be thin on both sides, so that the light energy power generation assembly can be rotated within a larger angle range under the premise of ensuring sufficient width, that is, the specific angle is expanded.

[0082] In a specific embodiment, as shown in Figure 4 The light energy power generation assembly 3 has an initial state, in which the light energy receiving surface 311 is parallel to the second adjusting part 22 (as shown in the first view of Figure 4 After the light energy power generation assembly 3 is rotated counterclockwise by an angle θ from the initial state, it interferes with the second adjusting part 22 (as shown in the second view of Figure 4As shown in the second figure), after the photovoltaic power generation component 3 is rotated clockwise by an angle θ from the initial state, it interferes with the second adjustment component 22 (as shown in the second figure). Figure 4 (As shown in the third figure), the specific angle is 2θ. In this embodiment, θ = 43°.

[0083] The plug-in portion 34 can be understood as a structure capable of being plugged in to achieve an electrical connection, such as a USB plug or a power plug. Figure 3 and Figure 4 In the illustrated embodiment, the plug-in portion 34 is constructed as a USB plug. Because the USB plug is elongated and flat, the detection body 1 rotates synchronously with the photovoltaic power generation component 3 at the specified angle. Figure 29 In the embodiment shown, the plug portion 34 is configured as a DC power plug. Since the DC power plug is cylindrical, the photovoltaic power generation component 3 can rotate independently at the specific angle.

[0084] Furthermore, such as Figure 4 As shown, the detection body 1 is constructed in a cylindrical shape. The difference between the radial width of the detection body 1 and the width of the outer shell assembly 35 is less than 10% of the radial width of the detection body 1, ensuring that the width of the light energy receiving surface 311 is sufficiently wide to guarantee power generation efficiency. The cylindrical shape has been explained in detail above and will not be repeated here. The radial width can be understood as the width on a plane perpendicular to the axial direction of the detection body 1.

[0085] In some embodiments, such as Figures 1-3 As shown, the insertion part 34 is located at the middle position of the end of the outer shell assembly 35, and an electrical connector 1332 is provided at the middle position of the end of the detection body 1. The insertion part 34 is inserted into the electrical connector 1332. The middle position can be understood as the position near the geometric center of the end face. In this embodiment of the invention, the electrical connector 1332 is located at the center of the end of the detection body 1, and the insertion part 34 is located at the middle position of the end of the photovoltaic power generation component 3, so that there is a certain distance between the photovoltaic power generation component 3 and the second adjusting member 22, providing rotation space for the photovoltaic power generation component 3.

[0086] Furthermore, such as Figure 6 and Figure 1As shown, the end protrusion of the detection main body 1 is provided with a circular boss 1321, the first adjusting member 21 is provided with a circular through hole 2111, the circular boss 1321 is embedded in the circular through hole 2111, and the circular boss 1321 can rotate based on the circular through hole 2111; the electrical plug interface 1332 is arranged on the end face of the circular boss 1321, so that the electrical plug interface 1332 can be exposed to the right-angle space, and thus the light energy power generation assembly 3 located in the right-angle space can be plugged into the electrical plug interface 1332.

[0087] Further, as shown in Figure 3 , the middle position of the side of the shell assembly 35 away from the light energy panel 31 is arched outward to form an arched position 3511, the arched position 3511 extends towards the third direction, and the third direction is the direction of the detection main body 1 towards the light energy power generation assembly 3; wherein the extension of the arched position 3511 towards the third direction does not affect the rotation angle range of the light energy power generation assembly 3, and increases the internal space of the arched position 3511.

[0088] Further, as shown in Figures 22-24 , the inside of the arched position 3511 is provided with an energy storage capacitor 33, and the energy storage capacitor 33 is used for storing electrical energy; since the energy storage capacitor 33 has a large volume, arranging it in the arched position 3511 can maximize the volume of the energy storage capacitor 33, guarantee the capacity of the energy storage capacitor 33, and the light energy power generation assembly 3 will not affect the rotation angle range due to accommodating the energy storage capacitor 33.

[0089] Further, as shown in Figure 6 and Figure 4 , the circular boss 1321 is provided with a button 1331, and the button 1331 is located on the side of the electrical plug interface 1332 away from the arched position 3511; when the light energy power generation assembly 3 is plugged into the detection main body 1, most or all areas of the button 1331 are not blocked by the light energy power generation assembly 3, so that the button 1331 can still be operated when the light energy power generation assembly 3 is plugged into the detection main body 1. In an embodiment, as shown in Figure 4 , the area of the button 1331 blocked by the light energy power generation assembly 3 is less than 10%.

[0090] In some embodiments, as shown in Figure 1 , the light energy power generation assembly 3 can be plugged into or pulled out of the electrical plug interface 1332 within the specific angle; as shown in Figure 11As shown, the detection main body 1 is provided with a button cell 15 at the end away from the electrical plug interface 1332, and when the light energy power generation assembly 3 is plugged into the detection main body 1, the button cell 15 cooperates with the light energy power generation assembly 3 to supply power to the detection main body 1. The cooperation of the button cell 15 and the light energy power generation assembly 3 in power supply can be understood as follows: when the light energy power generation assembly 3 has sufficient power, the light energy power generation assembly 3 is used for power supply, and when the light energy power generation assembly 3 has insufficient power, the button cell 15 is switched to power supply, thereby greatly improving the endurance of the button cell 15. The button cell 15 is arranged at the end away from the electrical plug interface 1332, which can avoid interference between the button cell 15 and the electrical plug interface 1332.

[0091] The light energy power generation assembly 3 provided by the present application adopts a pluggable design and cooperates with the button cell 15 for power supply, and can realize diversified use scenarios: when the use scenario is relatively complex, the light energy power generation assembly 3 can be detached, and only the button cell 15 is used for power supply, at this time, the rotatable range of the human body detection device 100 is very wide, and has multiple adjustable rotation degrees, which can meet the adjustment requirements of the detection direction which are relatively harsh; when the use scenario is relatively conventional, the detection direction does not need to be adjusted too much, at this time, the light energy power generation assembly 3 can be installed to improve the endurance of the button cell 15.

[0092] Further, the USB jack can also be plugged into a USB data line, and the USB data line is connected to a power adapter, and the detection main body 1 is powered by the power adapter. Further, the USB jack is a Type-C interface.

[0093] In some embodiments, as shown in Figure 6 As shown, the edge of the first adjusting part 21 is rotationally connected with the second adjusting part 22, and the rotation axis of the second adjusting part 22 relative to the first adjusting part 21 is the second rotation axis 24; the rotation axis of the detection main body 1 relative to the first adjusting part 21 is the first rotation axis 23; the first rotation axis 23 is perpendicular to and does not intersect with the second rotation axis 24, and the first rotation axis 23 and the second rotation axis 24 cooperate with each other to flexibly adjust the detection direction in a three-dimensional space. The first rotation axis 23 and the second rotation axis 24 can be understood as rotation center axes, not physical axes. The perpendicularity of the first rotation axis 23 and the second rotation axis 24 can be understood as verticality in space, not verticality in a plane.

[0094] The existing human body sensor is compatible with a base, generally the keys and the power interface are arranged on the side, and once the base is installed in place, the keys and the power interface are often blocked or close to the wall, resulting in inconvenience in operation of the keys and the power plug.

[0095] To solve the above problems, in the embodiments of the present application, as shown inFigure 1 and Figure 6 As shown in the figure, the adjusting support 2 comprises a first adjusting part 21 and a second adjusting part 22 rotatably connected to the first adjusting part 21; the detection direction of the detection main body 1 is lateral, the first adjusting part 21 is provided with a first clamping part 211, the bottom of the detection main body 1 is provided with a second clamping part 132, the second clamping part 132 is embeddedly clamped to the first clamping part 211, and the second clamping part 132 can rotate based on the first clamping part 211; the second clamping part 132 is provided with an operation part 133 for triggering an electronic switch 126 inside the detection main body 1 and / or connecting a power supply device, the operation part 133 is located on the bottom surface of the second clamping part 132, and when the second clamping part 132 is embedded in the first clamping part 211, the operation part 133 is exposed outside through the first clamping part 211. Wherein, the operation part 133 exposed outside through the first clamping part 211 can be understood as that the first clamping part 211 is provided with a through hole or a notch, so that the operation part 133 is not blocked by the first clamping part 211, and a user can directly touch the operation part 133. In an embodiment, the first clamping part 211 is provided with a circular through hole 2111, and the operation part 133 is located inside the circular through hole 2111, and the operation part 133 is exposed downward through the circular through hole 2111.

[0096] In a daily use scene, the detection direction is generally adjusted to be horizontal. Since the detection direction of the detection main body 1 of the embodiment is lateral, the bottom of the detection main body 1 is directed downward in a conventional use case, and the direction of the bottom of the detection main body 1 is relatively stable regardless of the rotation of the detection direction. The operation part 133 (the key 1331 and / or the power supply interface) is arranged at the bottom of the detection main body 1 in the embodiment, so as to avoid that the operation part 133 is close to a wall and is exposed downward, thereby facilitating the operation of the key 1331 and the plug-in electrical plug-in interface 1332. When the operation part 133 is plugged with a power cord, the power cord is not easy to interfere with other components.

[0097] In addition, the second clamping part 132 is not only used for arranging the operation part 133, but also used for supporting the detection main body 1 and rotating the detection direction, so as to integrate the functions of supporting, adjusting and operating in one structure, thereby realizing high structural integration.

[0098] It is worth mentioning that when the second adjusting part 22 is installed on a horizontal plane, the second adjusting part 22 is folded with the first adjusting part 21, so that the operation part 133 is hidden between the first adjusting part 21 and the second adjusting part 22, thereby improving the integrity of the appearance.

[0099] Benefiting from the double-rotation-axis cooperation between the detection main body 1 and the second adjusting member 22, the detection main body 1 can be freely rotated in the horizontal and pitching directions, and the user can infinitely adjust the detection main body 1 to the optimal angle, and when the user's adjusting operation is removed, the friction of the rotation axis can support the detection main body 1 to keep the current direction.

[0100] When the adjusting support 2 is pasted at a higher position or a relatively narrow position, it is relatively inconvenient to replace the button cell 15, and benefiting from the fact that the second clamping part 132 is rotatably clamped to the first clamping part 211, the user can disassemble the detection main body 1 from the adjusting support 2, so as to more conveniently replace the button cell 15. When installing, no tools are needed, and only the second clamping part 132 needs to be embedded in the first clamping part 211, and a "click" sound can be heard to complete the installation, which is convenient and fast.

[0101] Further, as shown in Figure 6 the second clamping part 132 includes a circular boss 1321 and a plurality of circumferential buckles 1322 distributed on the side surface of the circular boss 1321, the first clamping part 211 includes a circular through hole 2111, the circular boss 1321 is embedded in the circular through hole 2111, and the circumferential buckles 1322 are clamped to the edge of the circular through hole 2111; the operation part 133 is located on the end surface of the circular boss 1321, and when the circular boss 1321 is embedded in the circular through hole 2111, the operation part 133 is exposed outside through the circular through hole 2111. Among them, the connection mode of the circular boss 1321 and the circular through hole 2111 clamping cooperation not only realizes the rotation pair constraint similar to the shaft hole cooperation, but also is convenient to assemble, only the circular boss 1321 needs to be embedded in the circular through hole 2111, so that the circumferential buckles 1322 are clamped to the side of the circular through hole 2111 away from the detection main body 1, and the installation can be completed; and the operation part 133 can be exposed downward through the circular through hole 2111, so as to facilitate the user to operate. The circumferential buckles 1322 can be understood as buckles distributed along the circumference of the circular boss 1321.

[0102] Further, the number of the circumferential buckles 1322 is three, and the three circumferential buckles 1322 are uniformly distributed along the circumference of the circular boss 1321.

[0103] Further, the operation part 133 includes a key 1331 and / or an electrical plug interface 1332, and in some embodiments, the key 1331 and the electrical plug interface 1332 are distributed side by side on the bottom surface of the circular boss 1321. The electrical plug interface 1332 can be a power supply jack, a USB jack, etc. In the embodiment shown in Figure 6 , the electrical plug interface 1332 is configured as a USB jack, and in the embodiment shown in Figure 29 , the electrical plug interface 1332 is configured as a DC power supply jack.

[0104] Further, as shown in Figure 6 and Figure 11 , the detection body 1 comprises a cylindrical shell 13, the circular boss 1321 is arranged at the bottom of the cylindrical shell 13, and the button 1331 is integrally connected to the cylindrical shell 13 through a connecting arm 134, when the first adjusting piece 21 is clamped on the circular boss 1321, the first adjusting piece 21 blocks the connecting arm 134. Wherein, the connecting arm 134 is used for connecting the button 1331 and providing a reset force for the button 1331, and the integrally formed connection of the button 1331 to the cylindrical shell 13 can simplify the assembly steps.

[0105] In some embodiments, as shown in Figure 11 and Figure 1 , when the circumferential buckle 1322 is clamped on the circular through hole 2111, the circular boss 1321 does not protrude from the side of the first adjusting piece 21 away from the detection body 1. That is, the circular boss 1321 does not protrude from the lower surface of the first adjusting piece 21, so that when the second adjusting piece 22 is folded on the first adjusting piece 21, the upper surface of the second adjusting piece 22 can be attached to the lower surface of the first adjusting piece 21. In an embodiment, the lower surface of the circular boss 1321 is flush with the lower surface of the first adjusting piece 21.

[0106] Further, as shown in Figure 8 and Figure 6 , the first clamping part 211 further comprises an annular groove 2112 arranged around the circular through hole 2111, the annular groove 2112 is located at the end of the circular through hole 2111 away from the detection body 1; the circumferential buckle 1322 is clamped on the annular groove 2112, and the circumferential buckle 1322 is contained in the annular groove 2112, so that the circular boss 1321 does not protrude from the side of the first adjusting piece 21 away from the detection body 1. Wherein, the annular groove 2112 surrounds the inside of the circular through hole 2111, so that the circumferential buckle 1322 can rotate 360° in the annular groove 2112, thereby realizing the 360° rotation of the detection body 1 in the horizontal direction.

[0107] Further, as shown in Figure 7 , the side of the circular through hole 2111 facing the detection body 1 is protrusively provided with an annular protrusion 2113, and the annular protrusion 2113 surrounds the circular through hole 2111. As shown in Figure 6As shown, the bottom surface of the cylindrical shell 13 is provided with an annular recess 1323 around the circular boss 1321, and when the circular boss 1321 is embedded in the circular through hole 2111, the annular protrusion 2113 is embedded in the annular recess 1323.

[0108] Further, as shown in Figure 6 and Figure 1 , the bottom of the detection body 1 is provided with a shallow groove 139 adapted to the first adjusting member 21, and when the first clamping part 211 is clamped to the second clamping part 132, the first adjusting member 21 is embedded in the shallow groove 139, and the first adjusting member 21 does not protrude from the bottom of the detection body 1.

[0109] The adjusting support 2 described above can provide two adjustable rotation degrees of freedom, and the two rotation degrees of freedom can cooperate to allow the detection body 1 to freely rotate in the horizontal and pitch directions, as shown in Figure 9 , when the second adjusting member 22 is pasted on a vertical wall, the detection body 1 is blocked by the wall, and only has a 90° adjustable range in the vertical direction, in combination with the 360° adjustable range of the detection body 1 in the horizontal direction, the actual detection direction can only be adjusted in the second and fourth quadrants, and cannot achieve four-quadrant dead-angle-free adjustment.

[0110] To solve the above problems, in the embodiment of the present application, as shown in Figures 6-8 , the rotation axis of the detection body 1 relative to the first adjusting member 21 is set as a first rotation axis 23; the rotation axis of the second adjusting member 22 relative to the first adjusting member 21 is set as a second rotation axis 24; the second adjusting member 22 has a magnetic attraction surface 2221 for being rotatably and magnetically connected to a mounted surface 200, the second rotation axis 24 is parallel to the magnetic attraction surface 2221, and the first rotation axis 23 is perpendicular to the second rotation axis 24, so that there are three adjustable rotation degrees of freedom between the detection body 1 and the mounted surface 200. That is, in Figure 9 , the second adjusting member 22 can be rotated to fit the wall surface, and through the cooperation of the three rotation degrees of freedom, the detection direction can be adjusted in the four quadrants without dead angle.

[0111] It is worth noting that the detection area of the detection body 1 is not a symmetrical area up and down and left and right, but an irregular area with unequal horizontal width and vertical width, and through the cooperation of the three rotation degrees of freedom, the phase angle of the detection area can also be adjusted, so that the horizontal direction and the vertical direction of the detection area are rotated and transformed, thereby more accurately controlling the detection area. As shown in Figure 9 , at this time, the second adjusting member 22 is rotated by 90° to fit the wall surface, although the detection direction does not change, but the horizontal direction and the vertical direction of the detection area are rotated and transformed, thereby changing the detection area.

[0112] In summary, through the cooperation of the three rotational degrees of freedom, the detection direction can be adjusted without dead angle, and the phase angle of the detection area can be randomly changed.

[0113] The magnetic surface 2221 can be understood as a surface with magnetic attraction function, and can be magnetically connected to the iron mounting surface. In the actual installation process, the second adjusting part 22 can be magnetically installed on the surface of the refrigerator or the iron cabinet door through the magnetic surface 2221, or an iron sheet can be pasted on the wall surface, and the magnetic surface 2221 is magnetically installed on the wall surface through the iron sheet. Since the magnetic connection is a surface constraint, it will not limit the rotational and translational degrees of freedom of the second adjusting part 22 in the direction parallel to the installed surface 200.

[0114] Further, as shown in Figure 8 The edge of the first adjusting part 21 is rotatably connected to the second adjusting part 22, so that the rotatable angle of the first adjusting part 21 is larger.

[0115] Further, as shown in Figure 8 The edge of the first adjusting part 21 is rotatably connected to the second adjusting part 22, so that the rotatable angle of the first adjusting part 21 is larger.

[0116] In some embodiments, as shown in Figure 8 The second adjusting part 22 includes a base 221 and a magnetic part 222, the first adjusting part 21 is rotatably connected to the base 221, the magnetic part 222 is embedded and installed on the side of the base 221 away from the first adjusting part 21, and the side of the magnetic part 222 away from the first adjusting part 21 forms the magnetic surface 2221. The magnetic part 222 can be understood as a magnetic part, such as a magnet, magnetic rubber, etc. Further, the base 221 is provided with a containing groove 2214, and the magnetic part 222 is embedded and adhesively fixed in the containing groove 2214.

[0117] The existing battery compartment cover of the smart home device generally adopts elastic buckle clamping. When the pulling force applied to the cover is too large, the buckle is easy to automatically release, which causes the battery compartment to be easily opened and has a safety hazard.

[0118] To solve the above problems, in some embodiments, as shown in Figures 10-16 The detection main body 1 further comprises a battery compartment structure, which comprises a compartment body 161 and a compartment cover 17. The compartment body 161 is provided with a first clamping arm 162 extending towards a first direction, and the side of the first clamping arm 162 is provided with a first clamping unit 1621; as shown in Figure 13 The compartment cover 17 is provided with a second clamping unit 1711, which is arranged to move towards the first direction to be clamped to the first clamping unit 1621. The first clamping unit 1621 limits the movement of the second clamping unit 1711 towards the second direction, which is opposite to the first direction. When the second clamping unit 1711 applies an abutting force to the first clamping unit 1621 towards the second direction, the abutting force generates a first torque relative to the first clamping arm 162. Wherein, the opening direction of the compartment cover 17 is the second direction, and the opening force received by the compartment cover 17 is converted into the abutting force F1 applied by the second clamping unit 1711 to the first clamping unit 1621.

[0119] Specifically, as shown in Figure 13 The extension direction of the first clamping arm 162 is opposite to the direction of the abutting force F1, and the first clamping arm 162 corresponds to a cantilever beam structure, and the root of the first clamping arm 162 corresponds to the fulcrum of the cantilever beam. Since the first clamping unit 1621 protrudes from the first clamping arm 162, the abutting force F1 is located on the outside of the first clamping arm 162, and the abutting force F1 forms the first torque T1 relative to the root of the first clamping arm. The direction of the first torque T1 is clockwise, and the first clamping arm 162 bends outward under the action of the first torque T1, so that the first clamping unit 1621 is offset outward, so that the first clamping unit 1621 is clamped more tightly with the second clamping unit 1711, avoiding the second clamping unit 1711 from being automatically detached when the opening force is too large, and eliminating the safety hazard.

[0120] In order to be able to open the compartment cover 17 when the battery needs to be replaced, in the present embodiment, as shown in Figure 13As shown, the first clamping arm 162 is provided with a pressing portion 1622 on the same side of the first clamping unit 1621, the pressing portion 1622 can receive a pressing force F2 to generate a second torque T2 relative to the first clamping arm 162, the direction of the second torque T2 is opposite to the direction of the first torque T1, the second torque T2 makes the first clamping unit 1621 disengage from the second clamping unit 1711. Wherein, since the pressing portion 1622 and the first clamping unit 1621 are located on the same side, the pressing force F2 received by the pressing portion 1622 is opposite to the protruding direction of the first clamping unit 1621, the pressing force F2 forms a second torque T2 in the counterclockwise direction relative to the root of the first clamping arm 162, the first clamping arm 162 bends inward under the action of the second torque T2, so that the first clamping unit 1621 shifts inward, the first clamping unit 1621 separates from the second clamping unit 1711, so that the second clamping unit 1711 can move in the second direction, and the cover 17 can be opened.

[0121] It is worth mentioning that when opening the cover 17, the cover 17 needs to be pried open when the pressing portion 1622 is in a pressed state, which requires the cooperation of both hands and cannot be opened with one hand, thereby avoiding the child opening the cover 17 to cause accidental ingestion of the button battery 15.

[0122] Further, as shown in Figure 13 , the cover 17 is arranged on the side of the cartridge body 161 facing the second direction, the cover 17 is provided with a second clamping arm 171 extending towards the first direction, and the second clamping unit 1711 is arranged on the side surface of the second clamping arm 171. Wherein, the advantage of arranging the second clamping arm 171 is that the position of the second clamping unit 1711 is further away from the cover 17, so that the distance between the first clamping unit 1621 and the root of the first clamping arm 162 is further, when the pressing portion 1622 is pressed, the first clamping unit 1621 and the root of the first clamping arm 162 can generate sufficient deformation, so that the offset of the first clamping unit 1621 is sufficient to make the second clamping unit 1711 smoothly disengage from the first clamping unit 1621, and the cover 17 can be opened.

[0123] Further, as shown in Figure 13 and Figure 12 , the side of the second clamping arm 171 away from the second clamping unit 1711 is provided with a prying portion 1712, the prying portion 1712 is used to receive a prying force to drive the second clamping arm 171 to move towards the second direction. Wherein, the prying force can be understood as the force applied by the user through the nail clamping the prying portion 1712. In some embodiments, the prying portion 1712 is configured as a horizontal strip-shaped recess on the side surface of the second clamping arm 171, and the user can use the nail to clamp the recessed part to apply the force in the second direction.

[0124] In some embodiments, as shown in Figure 13 the first clamping arm 162 extends from the side of the cartridge body 161, and the second clamping arm 171 extends from the side of the cartridge cover 17. Further, the inner side of the second clamping arm 171 abuts against the outer side of the first clamping arm 162 to enhance the clamping stability of the second clamping unit 1711 and the first clamping unit 1621.

[0125] In some embodiments, as shown in Figure 13 the first clamping arm 162 includes a connecting end connected to the cartridge body 161 and a free end away from the connecting end, the pressing portion 1622 is arranged at the free end, and the first clamping unit 1621 is arranged between the pressing portion 1622 and the connecting end.

[0126] Further, the second clamping unit 1711 is arranged at the end of the second clamping arm 171, i.e., the end of the second clamping arm 171 is located at the corresponding position of the first clamping unit 1621, so that the second clamping arm 171 does not block the pressing portion 1622.

[0127] Further, as shown in Figure 13 the first clamping unit 1621 includes a first buckle, and the second clamping unit 1711 includes a second buckle, the second buckle is movable towards the first direction to be clamped to the first buckle, and the first buckle limits the movement of the second buckle towards the second direction.

The detection module includes the infrared pyroelectric module 111 and the radar module 124. The fixed connection can be buckle clamping, screw connection or other fixed connection.

[0129] Further, as shown in Figure 11 and Figure 10As shown, the pressing portion 1622 includes a button which protrudes from the side of the first clamping arm 162, and the cylindrical shell 13 is provided with a pressing hole 138 corresponding to the position of the button, and the button is exposed outside through the pressing hole 138. Further, the button protrudes from the side of the cylindrical shell 13 through the pressing hole 138, so that the user can press the button to form a sufficient deformation of the first clamping arm 162, and the first clamping unit 1621 is separated from the second clamping unit 1711.

[0130] In some embodiments, as shown in Figure 11 and Figure 12 As shown, the side of the cover 17 extends a second clamping arm 171, and the second clamping arm 171 is provided with the second clamping unit 1711. The side of the cover 17 away from the second clamping arm 171 is provided with a plug-in structure 172 which is plugged into the cylindrical shell 13 or the cartridge body 161. Wherein, the side of the cover 17 is limited by plugging, which is more stable than clamping, and can effectively prevent the cover 17 from separating from the cartridge body 161 on the side of plugging.

[0131] In an embodiment, as shown in Figure 11 , Figure 12 As shown, the side of the cover 17 is provided with the plug-in structure 172 which is plugged into the cylindrical shell 13, and the side of the cover 17 away from the plug-in structure 172 is clamped into the limiting shell 16. The inner wall of the side of the cylindrical shell 13 away from the second clamping arm 171 is provided with a plug-in position 135. During installation, the plug-in structure 172 is first plugged into the plug-in position 135, and then the second clamping unit 1711 is clamped into the first clamping unit 1621.

[0132] Further, as shown in Figure 10 and Figure 12 As shown, the cylindrical shell 13 is provided with a matching groove 136 which is matched with the second clamping arm 171, and the second clamping arm 171 is embedded in the matching groove 136, so that the second clamping arm 171 can extend to the corresponding position of the first clamping unit 1621, and thus the second clamping unit 1711 can be clamped into the first clamping unit 1621. The second clamping arm 171 is embedded in the matching groove 136 to close the matching groove 136.

[0133] In some embodiments, as shown in Figure 14As shown, the upper end of one side of the bin body 161 is provided with a limiting wall 1611, and the side wall of the other side is provided with an abutting protrusion (not shown in the figure), the limiting wall 1611 abuts the upper surface of the button cell 15, and the abutting protrusion abuts the side surface of the button cell 15, the upper end of the bin body 161 is open, and the button cell 15 is loaded into the bin body 161 by the upper end of the bin body 161; The first circuit board 11 is welded with a positive electrode spring 113 and a negative electrode spring 114, the positive electrode spring 113 abuts the side surface of the button cell 15, and the negative electrode spring 114 abuts the bottom surface of the button cell 15. The bin body 161 is provided with a square through hole corresponding to the positive electrode spring 113 and the negative electrode spring 114, and the square through hole is used for the positive electrode spring 113 and the negative electrode spring 114 to pass through.

[0134] In the installation of the button cell 15, first, one side of the battery is inserted below the limiting wall 1611, and then the button cell 15 is pressed into the bin body 161. In the prior art, because the limiting wall 1611 is generally not located at the position corresponding to the positive electrode spring 113, the lower surface of the button cell 15 may touch the positive electrode spring 113 and the negative electrode spring 114 at the same time during the pressing of the button cell 15 into the bin body 161, which may cause damage to the first circuit board 11. Therefore, in the embodiment of the present application, the positive electrode spring 113 is arranged at the position corresponding to the limiting wall 1611, so that when the button cell 15 is inserted below the limiting wall 1611, the side surface of the button cell 15 abuts the positive electrode spring 113, and at this time, the end of the button cell 15 close to the positive electrode spring 113 is inclined downward, so that the lower surface of the button cell 15 cannot contact the positive electrode spring 113, thereby avoiding the short circuit of the positive electrode spring 113 and the negative electrode spring 114, and when the button cell 15 is pressed into the bin body 161, the lower surface of the button cell 15 abuts the negative electrode spring 114.

[0135] The existing human body sensor generally installs a lens shell at the end of the shell, the back of the lens shell is provided with a plug-in ring, the end of the shell is provided with a plug-in groove matched with the plug-in ring, and during assembly, the plug-in ring needs to be glued around, and then the plug-in ring is inserted into the plug-in groove, and attention also needs to be paid to the positioning structure between the plug-in ring and the plug-in groove, which results in low assembly efficiency.

[0136] To solve the above problems, in the embodiment of the present application, as shown in Figure 11 , Figure 18 and Figure 19As shown, the detection body 1 includes: a first circuit board 11, a lens carrier 14, and a limiting housing 16; the first circuit board 11 is disposed inside the cylindrical housing 13, and the first circuit board 11 is provided with an infrared pyroelectric module 111; the lens carrier 14 is installed on the side of the cylindrical housing 13, and the lens carrier 14 includes a lens assembly 141, which is used to focus infrared light onto the infrared pyroelectric module 111; the limiting housing 16 is disposed at the end of the cylindrical housing 13, and the limiting housing 16 accommodates a button battery 15, and the first circuit board 11, the lens carrier 14, and the button battery 15 are all limited by the limiting housing 16. During assembly, the first circuit board 11 and the lens carrier 14 are simply placed into their corresponding positions inside the cylindrical housing, and then the limiting housing 16 is installed into the cylindrical housing. The limiting housing 16 can limit the first circuit board 11 and the lens carrier 14, which greatly improves the assembly efficiency. In addition, the limiting housing 16 is also used to accommodate the button battery 15, realizing the diversification of the function of the limiting housing 16, thereby simplifying the internal structure of the detection body 1, reducing the number of parts, and helping to reduce the volume of the detection body 1.

[0137] The limiting housing 16 is recessed towards the interior of the cylindrical outer shell 13 to form the compartment 161, and the button battery 15 is installed inside the compartment 161. The lens carrier 14 includes an arched sheet 142 and the lens assembly 141, the lens assembly 141 being integrally formed on the back side of the arched sheet 142.

[0138] Furthermore, such as Figure 11 As shown, the limiting housing 16 is embedded in the cylindrical outer shell 13, and the side of the limiting housing 16 is engaged with the inner wall of the cylindrical outer shell 13. Further, the limiting housing 16 includes a cylindrical compartment 161, the size of which is adapted to the internal dimensions of the cylindrical outer shell 13. The limiting housing 16 covers the top of the cylindrical outer shell 13, thereby limiting the first circuit board 11 inside the cylindrical outer shell 13. Figure 16 As shown, two long-arm latches 163 extend downward from the side of the limiting housing 16 near the second latching arm 171. The latching directions of the two long-arm latches 163 are opposite. A slot 164 is provided on the side of the limiting housing 16 away from the second latching arm 171, as shown. Figure 20 As shown, a third buckle 1371 is provided on the inner wall of the cylindrical outer shell 13 at the position corresponding to the long arm buckle 163, and a fourth buckle 1372 is provided at the position corresponding to the slot 164. The long arm buckle 163 is engaged with the third buckle 1371, and the slot 164 is engaged with the fourth buckle 1372, thereby realizing the stable connection of the limiting shell 16 to the inside of the cylindrical outer shell 13.

[0139] Furthermore, such asFigure 12 and Figure 13 As shown in the figure, the detection main body 1 further comprises a cover 17, the cover is arranged on the limiting shell 16, the button cell 15 is limited between the limiting shell 16 and the cover 17, and the cover 17 is limited by the limiting shell 16, so that the function of the limiting shell 16 is diversified, and the structure of the detection main body 1 is simplified. The cover 17 is arranged on the top of the cylindrical shell 13 to close the top of the cylindrical shell 13. The technical details of the cover 17 have been described in detail above, and will not be repeated here.

[0140] In some embodiments, as shown in the figure, Figure 14 The first circuit board 11 and the button cell 15 are respectively located on both sides of the limiting shell 16, the first circuit board 11 is welded with a positive electrode spring 113 and a negative electrode spring 114, and the positive electrode spring 113 and the negative electrode spring 114 respectively pass through the limiting shell 16 and abut against the button cell 15.

[0141] Further, as shown in the figure, Figure 11 The first circuit board 11 is limited by the limiting shell 16 and the cylindrical shell 13. Further, as shown in the figure, Figure 20 The inner wall of the cylindrical shell 13 is provided with a first sliding groove 1373 on both sides, and the two sides of the first circuit board 11 are respectively slid into the first sliding groove 1373. As shown in the figure, Figure 16 and Figure 18 The limiting shell 16 is provided with a first limiting groove 165, one end of the first circuit board 11 is limited by the first limiting groove 165, and the other end abuts against the cylindrical shell 13.

[0142] Further, the first sliding groove 1373 extends in the vertical direction, the first circuit board 11 is slid into the first sliding groove 1373 from top to bottom, the bottom of the first circuit board 11 abuts against the bottom wall of the cylindrical shell 13, the top of the first circuit board 11 is inserted into the first limiting groove 165, and the top surface abuts against the top end of the first limiting groove 165. Further, the number of the first limiting groove 165 is two, which is distributed on both sides of the bottom of the limiting shell 16, and the two first limiting grooves 165 jointly limit the first circuit board 11, so that the first circuit board 11 is stably and accurately limited.

[0143] In some embodiments, as shown in the figure, Figures 14-18As shown, the detection main body 1 further comprises a second circuit board 12, which is provided with a radar module 124, and is limited by the limiting shell 16 and the cylindrical shell 13. When the limiting shell 16 is installed into the cylindrical shell 13, the second circuit board 12 can be limited, thereby improving the assembly efficiency, and without the need of additional parts to limit the second circuit board 12, so that the internal structure of the detection main body 1 is more compact.

[0144] Further, as shown in Figure 15 、 Figure 17 and Figure 18 , the second circuit board 12 is parallel to the first circuit board 11, and is integrally installed into the cylindrical shell 13 with the first circuit board 11 through the pin header 121 and the female header 115, thereby improving the assembly efficiency and improving the relative position accuracy between the first circuit board 11 and the second circuit board 12.

[0145] Further, as shown in Figure 17 , one side of the first circuit board 11 facing the second circuit board 12 is provided with two female headers 115, and one side of the second circuit board 12 facing the first circuit board 11 is provided with two pin headers 121, and the two pin headers 121 are respectively inserted into the two female headers 115. When the second circuit board 12 is inserted into the female header 115 through the pin header 121, the positional relationship between the second circuit board 12 and the first circuit board 11 can be accurately positioned, so that the second circuit board 12 and the first circuit board 11 can be smoothly installed into the cylindrical shell 13, thereby improving the assembly efficiency. Further, the distribution direction of the two female headers 115 is perpendicular to the extension direction of the first sliding groove 1373.

[0146] In some embodiments, as shown in Figure 20 , the inner wall of the cylindrical shell 13 is respectively provided with a second sliding groove 1374 on both sides, and the two sides of the second circuit board 12 are respectively slid into the second sliding groove 1374; as shown in Figure 16 and Figure 18 , the limiting shell 16 is provided with a second limiting groove 166, one end of the second circuit board 12 is limited by the second limiting groove 166, and the other end abuts against the cylindrical shell 13.

[0147] Furthermore, the second slide groove 1374 extends vertically, and the second circuit board 12 slides into the second slide groove 1374 from top to bottom. The bottom of the second circuit board 12 abuts against the bottom wall of the cylindrical housing 13, and the top of the second circuit board 12 is inserted into the second limiting groove 166, with its top surface abutting against the top of the second limiting groove 166. Furthermore, there are two second limiting grooves 166, distributed on both sides of the bottom of the limiting housing 16. The two second limiting grooves 166 together limit the second circuit board 12, thereby ensuring that the second circuit board 12 is stably and precisely positioned.

[0148] In some embodiments, such as Figure 15 As shown, one end of the cylindrical housing 13 is open, and the first circuit board 11, the lens carrier 14, and the limiting housing 16 are inserted into the cylindrical housing 13 through the open end; as Figure 19 and Figure 20 As shown, a third limiting groove 1375 is provided at the end of the cylindrical outer shell 13 away from the open end, and the first end (i.e., the lower end) of the lens carrier 14 is inserted into the third limiting groove 1375. Further, the top of the cylindrical outer shell 13 is open and the bottom is closed. Multiple limiting ribs extend upward from the bottom wall of the cylindrical outer shell 13 near the side wall. Each limiting rib is arranged along the side wall of the cylindrical outer shell 13. The bottom of the lens carrier 14 is sandwiched between the limiting ribs and the side wall of the cylindrical outer shell 13, forming the third limiting groove 1375, which is an arc-shaped groove.

[0149] like Figure 11 As shown, the limiting housing 16 is installed at the open end of the cylindrical outer shell 13, and the second end (i.e., the upper end) of the lens carrier 14, away from the first end, is inserted between the limiting housing 16 and the cylindrical outer shell 13; wherein, as Figure 16 As shown, a limiting arc groove 167 is provided on the side of the limiting housing 16 near the bottom. The limiting arc groove 167 surrounds half of the side of the limiting housing 16. When the limiting housing 16 is installed on the cylindrical outer shell 13, a limiting gap is formed between the limiting arc groove 167 and the side wall of the cylindrical outer shell 13. Figure 11 As shown, the upper end of the lens carrier 14 is inserted upward into the limiting gap, so that the upper end of the lens carrier 14 is clamped between the limiting housing 16 and the side wall of the cylindrical housing 13.

[0150] Furthermore, the second end, i.e. the upper end, of the lens carrier 14, and the first end, i.e. the lower end, of the lens carrier 14.

[0151] like Figure 16As shown, the limiting shell 16 is provided with a third abutting wall at the corresponding position of the second end of the lens carrier 14, which is used to limit the end face of the second end of the lens carrier 14. The third abutting wall is the top wall of the limiting arc groove 167. When the limiting shell 16 is installed in the cylindrical shell 13, the upper end of the lens carrier 14 is inserted into the limiting gap upward, and the upper end face of the lens carrier 14 abuts against the third abutting wall or there is a small gap between the third abutting wall, so that the lens carrier 14 is limited to move upward by the third abutting wall. Further, the bottom of the lens carrier 14 abuts against the bottom wall of the third limiting groove 1375, so that the position of the lens limiting piece in the vertical direction is completely limited.

[0152] Further, as shown in Figure 19 and Figure 20 , the lens carrier 14 includes an arc-shaped sheet 142 and a lens assembly 141 provided on the back of the arc-shaped sheet 142. The arc-shaped sheet 142 includes a first side and a second side between the first end and the second end. The cylindrical shell 13 is provided with a fourth limiting groove 1376 and a fifth limiting groove at the corresponding positions of the first side and the second side of the arc-shaped sheet 142, respectively. The first side and the second side are respectively inserted into the fourth limiting groove 1376 and the fifth limiting groove. The fourth limiting groove 1376 and the fifth limiting groove limit the two sides of the arc-shaped sheet 142 to limit the shape of the arc-shaped sheet 142. Further, the first side and the second side of the arc-shaped sheet 142 are respectively the left side and the right side. The bottom wall of the cylindrical shell 13 extends upward on both sides to form the fourth limiting groove 1376 and the fifth limiting groove between the long strip-shaped ribs and the inner wall of the cylindrical shell 13.

[0153] Further, as shown in Figure 19 and Figure 20 , the cylindrical shell 13 is provided with a first abutting wall 1377 and a second abutting wall at the corresponding positions of the first side and the second side of the arc-shaped sheet 142, respectively. The end faces of the first side and the second side of the arc-shaped sheet 142 abut against the first abutting wall 1377 and the second abutting wall, respectively. The first abutting wall 1377 and the second abutting wall provide abutting force for the two sides of the arc-shaped sheet 142 to support the two sides of the arc-shaped sheet 142 to fit the inner wall of the cylindrical shell 13 and maintain the arc shape. When the arc-shaped sheet 142 is subjected to external pressure, the first abutting wall 1377 and the second abutting wall can support the arc-shaped sheet 142 not to be deformed.

[0154] As shown in Figure 19As shown, the lower end of the arched sheet 142 is inserted into the third limiting groove 1375, which can support the inner side of the arched sheet 142, so that the lower part of the arched sheet 142 can resist external pressure, but the upper end of the inner wall of the arched sheet 142 lacks support and is at risk of deformation under external pressure. Therefore, in a further embodiment, as shown in Figure 21 As shown, the arched sheet 142 is provided with a protrusion 1421 on each side towards the side surface, which is located on the upper part of the arched sheet 142, and is used to abut against the first abutting wall 1377 and the second abutting wall, so that the support force on both sides of the upper part of the arched sheet 142 is stronger, improving the anti-deformation ability of the upper part of the arched sheet 142, and the upper part of the arched sheet 142 can be tightly attached to the inner wall of the cylindrical shell 13.

[0155] Further, as shown in Figure 16 When the limiting shell 16 is loaded into the cylindrical shell 13, the top wall (i.e. the third abutting wall) of the limiting arc groove 167 of the limiting shell 16 limits the upward movement of the second end of the lens carrier 14; in addition, as shown in Figure 19 As shown, the inner wall of the cylindrical shell 13 is provided with a limiting block 1378 for limiting the second end of the arched sheet 142. The limiting block 1378 and the third abutting wall both limit the upward movement of the second end of the arched sheet 142, but there is a certain gap between the limiting block 1378 and the second end of the arched sheet 142. When the third abutting wall limits the arched sheet 142, the limiting block 1378 does not contact the arched sheet 142. The function of the limiting block 1378 is to limit the arched sheet 142 from coming out of the cylindrical shell 13 when the limiting shell 16 is not loaded into the cylindrical shell 13, so that the arched sheet 142 and the cylindrical shell 13 remain in an assembled relationship.

[0156] Because the back surface of the arched sheet 142 is integrally formed with the Fresnel lens, the difficulty of injection molding of the arched sheet 142 is relatively high. Therefore, in the embodiment of the application, as shown in Figure 21 The arched sheet 142 can be unfolded into a flat panel shape, so that the arched sheet 142 can be first processed into a flat panel structure and then curled into an arched shape, greatly reducing the processing difficulty.

[0157] In an embodiment, as shown in Figure 21 and Figure 19As shown, the lens assembly 141 is spliced by a plurality of lens units 1411, the lens units 1411 are configured as Fresnel lenses, and each lens unit 1411 is integrally formed on the arched sheet 142. The lens assembly 141 is a left-right symmetrical design, including 10 small lens units 1411 in the middle, and one large lens unit 1411 at the left end and the right end, wherein the 10 small lens units 1411 in the middle are distributed in two layers, and each layer has five lens units 1411 arranged side by side.

[0158] The infrared pyroelectric module 111 can only sense the moving infrared heat source, when the person is static (such as sitting, sleeping), the infrared pyroelectric module 111 cannot sense the human body, and the radar module 124 can detect the slight movement of the human body, including breathing, heartbeat, etc., so even if the person is static, the radar can continuously detect the human body, which makes up for the short board of the infrared pyroelectric module 111. Moreover, the radar module 124 is very sensitive, and sometimes it may misjudge the curtain shaking, fan rotating as someone being present, the infrared pyroelectric module 111 is not sensitive to the movement of non-heat source, which can make up for the problem of easy misjudgment of the radar module 124. Moreover, the radar module 124 also needs to continuously emit radar waves when there is no one, which belongs to active detection and consumes more power, while the infrared pyroelectric module 111 passively detects the infrared heat source, which belongs to passive detection and consumes less power.

[0159] The human body detection device 100 provided by the application integrates the infrared pyroelectric module 111 and the radar module 124, and organically combines the two: when there is no one in the detection area, the radar module 124 suspends work, and only relies on infrared pyroelectric detection, which not only saves power, but also avoids the radar module 124 from being mis-triggered; when there is someone in the detection area, the radar module 124 is turned on, and detection is performed through the radar module 124, which avoids the inability to sense a static human body. The advantages of the radar module 124 and the infrared pyroelectric module 111 are complementary, which greatly improves the performance of the human body detection device 100.

[0160] In terms of structural design, if the radar module 124 and the infrared pyroelectric module 111 are simply combined together, it will cause the shell and the internal structure to be complex and bulky, and the overall volume will be large.

[0161] To solve the above problems, in the embodiment of the application, as shown in Figure 11 、 Figures 15-21As shown, the cylindrical shell 13 is internally provided with an infrared pyroelectric module 111 and a radar module 124; a detection window 131 is formed on the side of the cylindrical shell 13, the detection window 131 is shielded by the arched sheet 142, the back of the arched sheet 142 is integrally provided with a lens assembly 141, the lens assembly 141 is used for converging infrared light to the infrared pyroelectric module 111, and the radar wave emitted by the radar module 124 is transmitted outward through the arched sheet 142. The infrared pyroelectric module 111 and the radar module 124 share one detection window 131, so that the structure is more compact.

[0162] In addition, in the prior art, the radar wave is directly transmitted outward through the shell, the radar wave is reflected by the object outside and then passes through the shell again to reach the radar module 124, and the radar module 124 judges whether there is a moving human body / object in the detection area according to the reflected wave. Since the shell has a relatively large thickness, the radar wave is attenuated, which affects the performance of the radar module 124. In the present embodiment, both the radar wave and the reflected wave pass through the arched sheet 142. Thanks to the relatively small thickness of the arched sheet 142, the attenuation of the radar wave passing through the arched sheet 142 is small, and the performance of the radar module 124 is better.

[0163] It is worth mentioning that the arched sheet 142 has a large circumferential angle in the horizontal direction, so that a large range of radar waves in the horizontal direction can pass through the arched sheet 142, which is beneficial to the wide-range detection of the radar module 124 in the horizontal direction.

[0164] In an embodiment, the infrared pyroelectric module 111 adopts a binary pyroelectric infrared sensor with a model number Z142M7 from Tinuva Opto Bright Technology Co., Ltd.; and the radar module 124 adopts a 24GHz millimeter wave radar sensor with a model number MRS261L from S&C.

[0165] Further, as shown in Figure 18 and Figure 21 The arched sheet 142 includes a lens region where the lens assembly 141 is arranged, and a smooth region where the lens assembly 141 is not arranged, the smooth region covers the radar module 124, and the lens region does not cover the radar module 124. Since the lens assembly 141 is composed of a plurality of Fresnel lenses, the Fresnel lenses have a plurality of annular textures, so that the thickness of the arched sheet 142 in the lens region changes greatly. In the present embodiment, the radar module 124 is arranged in the covered area of the smooth region, so that most of the radar waves pass through the smooth region, avoiding the adverse effects of the lens assembly 141 on the radar waves.

[0166] In the present embodiment, the arched sheet 142 is provided with a plurality of annular textures, so that the thickness of the arched sheet 142 in the lens region changes greatly. In the present embodiment, the radar module 124 is arranged in the covered area of the smooth region, so that most of the radar waves pass through the smooth region, avoiding the adverse effects of the lens assembly 141 on the radar waves. Figure 18As shown, the lens region does not cover the radar module 124 can be understood as, the lens region on the plane of the projection of the radar module 124 and the radar module 124 has no overlapping area.

[0167] In some embodiments, as shown in Figure 17 and Figure 18 As shown, the cylindrical shell 13 is internally provided with a first circuit board 11 and a second circuit board 12, the infrared pyroelectric module 111 is arranged on the first circuit board 11, the radar module 124 is arranged on the second circuit board 12, the second circuit board 12 is located between the first circuit board 11 and the arc-shaped sheet 142, and the second circuit board 12 is provided with a first through slot 122 at a position corresponding to the infrared pyroelectric module 111. Wherein, according to the light condensing principle of the lens assembly 141, there must be a light condensing distance between the lens assembly 141 and the infrared pyroelectric module 111, which makes the light converge. In this embodiment, the second circuit board 12 is arranged between the first circuit board 11 and the lens assembly 141, which reasonably utilizes the space generated by the light condensing distance, so that the space utilization is higher and the structure is more compact.

[0168] Furthermore, the first circuit board 11 and the second circuit board 12 are stacked along the radial direction of the cylindrical shell 13, which reasonably utilizes the radial space of the cylindrical shell 13 and avoids the infrared pyroelectric module 111 and the radar module 124 being arranged on one circuit board to cause the circuit board to be too large.

[0169] The first through slot 122 is arranged at the edge position of the second circuit board 12 and penetrates the second circuit board 12, which is used for infrared light to pass through, so as to avoid the second circuit board 12 shielding the converged infrared light to cause the infrared pyroelectric module 111 to be invalid. The top of the second circuit board 12 is limited by the limiting shell 16 in the area on both sides of the first through slot 122, so as to improve the stability of the second circuit board 12.

[0170] Further, as shown in Figure 17 and Figure 18 As shown, the first circuit board 11 is provided with a brightness sensing piece 116, a pad piece 117 is arranged between the brightness sensing piece 116 and the first circuit board 11, the pad piece 117 supports the brightness sensing piece 116, the second circuit board 12 is provided with a second through slot 123 at a position corresponding to the brightness sensing piece 116, and the brightness sensing piece 116 is embedded in the second through slot 123. Wherein, the ambient light transmits through the arc-shaped sheet 142 and irradiates to the brightness sensing piece 116, the pad piece 117 supports the brightness sensing piece 116, so that the end surface of the brightness sensing piece 116 can protrude from the side of the second circuit board 12 facing the arc-shaped sheet 142, avoiding the second circuit board 12 shielding the light, so that the brightness sensing piece 116 can more accurately sense the ambient light.

[0171] Further, the pad piece 117 is configured as a plastic cylinder, and the brightness sensing piece 116 adopts a photoresistor, and the pin of the photoresistor is welded to the first circuit board 11 through the plastic cylinder.

[0172] Further, as shown in the figure, Figure 17 The second circuit board 12 is provided with an LED indicator lamp 125 facing the lens carrier 14, and the light emitted by the LED indicator lamp 125 is transmitted outward through the lens carrier 14.

[0173] Further, as shown in the figure, Figure 17 The first circuit board 11 is provided with an on-board antenna 118 near the side edge. The second circuit board 12 is recessed inward on both sides to avoid shielding the signal of the on-board antenna 118.

[0174] In some embodiments, as shown in the figure, Figure 11 The open end of the cylindrical shell 13 is mounted with the limiting shell 16, and the limiting shell 16 is provided with a first limiting groove 165 and a second limiting groove 166, and the first circuit board 11 is limited by the first limiting groove 165, and the second circuit board 12 is limited by the second limiting groove 166.

[0175] The small light energy power generation panel on the market generally does not have a storage function. The reason is that the advantage of the small light energy panel is small size and thin thickness. If a charging battery is installed inside, the volume will be greatly increased, which will limit the use scene. However, since the small light energy panel does not have a storage function, it cannot supply power at night, and the powered device needs to be equipped with a charging battery to cooperate with it, which has a relatively harsh use condition.

[0176] To solve the above problems, in the embodiment of the present application, as shown in the figure, Figure 3 , Figures 22-29 A light energy power generation assembly 3 is provided, which is suitable for power supply of electronic devices with small power demand, such as sensors. The light energy power generation assembly 3 comprises a shell assembly 35, a light energy panel 31 and a third circuit board 32, the light energy panel 31 is installed on one side of the shell assembly 35; the third circuit board 32 is arranged inside the shell assembly 35, and the third circuit board 32 is electrically connected to the light energy panel 31; wherein the third circuit board 32 is provided with a receiving part 321, and at least one energy storage capacitor 33 is arranged in the receiving part 321, the energy storage capacitor 33 is embedded in the receiving part 321 in a horizontal and inverted manner, and the pin of the energy storage capacitor 33 is welded to the third circuit board 32 in a bent manner.

[0177] In the embodiment of the present application, the energy storage capacitor 33 is installed in the light energy power generation assembly 3, so that the electricity generated by the light energy power generation assembly 3 during the day can be stored for use at night, thereby realizing uninterrupted power supply for 24 hours a day.

[0178] The energy storage capacitor 33 is embedded in the third circuit board 32 in a horizontal manner, i.e., the energy storage capacitor 33 changes from a state perpendicular to the third circuit board 32 to a state inclined or parallel to the third circuit board 32, so that the height of the energy storage capacitor 33 protruding from the third circuit board 32 is greatly reduced, and the thickness of the light energy power generation assembly 3 is controlled.

[0179] The accommodating portion 321 can be a through hole or a through slot at the edge of the third circuit board 32, and the horizontal manner can be understood as the energy storage capacitor changing from a state perpendicular to the third circuit board 32 to a state inclined or parallel to the third circuit board 32.

[0180] Further, as shown in Figure 24 and Figure 28 , the accommodating portion 321 is configured as an accommodating hole, the energy storage capacitor 33 includes a cylindrical capacitor column and the pin provided at the end of the capacitor column, the capacitor column is embedded in the accommodating hole, and the axial direction of the capacitor column is parallel to the third circuit board 32, so that the height of the energy storage capacitor 33 protruding from the third circuit board 32 is further reduced, and the thickness of the light energy power generation assembly 3 can be further reduced.

[0181] Further, as shown in Figure 23 , the two sides of the capacitor column protrude from the two sides of the third circuit board 32, so that the space on the upper and lower sides of the third circuit board 32 is fully utilized to place the capacitor column, and the height of the energy storage capacitor 33 protruding from the third circuit board 32 is further reduced.

[0182] In some embodiments, as shown in Figures 22-26 , the number of energy storage capacitors 33 is one, and the energy storage capacitor 33 is a lithium ion capacitor. The lithium ion capacitor has the advantage of super large capacity and can store more electric energy, but multiple lithium ion capacitors cannot be connected in parallel, so only one lithium ion capacitor is provided in this embodiment. In an embodiment, the lithium ion capacitor is a 15-farad lithium ion capacitor.

[0183] In another embodiment, as shown in Figures 27-28 , the difference between this embodiment and the embodiment of Figures 22-26 is that the number of energy storage capacitors 33 is multiple, the capacitor columns of the energy storage capacitors 33 are coaxially arranged, the positions and the number of the accommodating holes are matched with the capacitor columns, and the energy storage capacitors 33 are super capacitors. Although the capacity of the super capacitor is smaller than that of the lithium ion capacitor, the capacity can be expanded by parallel connection. In this embodiment, the number of energy storage capacitors 33 is two, and the two energy storage capacitors 33 are connected in parallel to increase the total capacity.

[0184] It is worth mentioning that, as shown in Figure 27 , thanks to the ability to be connected in parallel between super capacitors, the embodiment can adopt multiple light energy power generation assemblies 3 connected end to end, thereby improving the total power generation and total energy storage. Further, the super capacitor adopts a 1-farad super capacitor.

[0185] In the embodiment shown in Figures 27-28 , one end of the third circuit board 32 is welded with a USB plug, the USB plug protrudes from the shell assembly 35, and the end of the third circuit board 32 away from the USB plug is welded with a USB female head 36, the shell assembly 35 is provided with a plug hole 3526 at the position corresponding to the USB female head 36, the USB plug, the USB female head 36 and each energy storage capacitor 33 are arranged in a straight line in the third direction, and the USB plug and the USB female head 36 are embedded in the third circuit board 32; taking a plane perpendicular to the third direction as a projection plane, the USB plug projects on the projection plane to form a first projection pattern, and the USB female head 36 projects on the projection plane to form a second projection pattern, and the second projection pattern covers the first projection pattern. Thus, when multiple light energy power generation assemblies 3 are connected end to end, each light energy power generation assembly 3 can be connected in a straight line.

[0186] In addition to the above differences, Figures 27-28 , the other structures of the embodiment are the same as those of the embodiment of Figures 1-26 . In Figure 28 , the double-sided adhesive tape 39 is not shown.

Among them, the arched part 3511 is located at the middle position of the arched shell 351, so that the shell assembly 35 is configured to have a shape of thick in the middle and thin on both sides. Since the energy storage capacitor 33 has a large volume, arranging it in the arched part 3511 can maximize the volume of the energy storage capacitor 33, guarantee the capacity of the energy storage capacitor 33, and the light energy power generation assembly 3 will not be affected by the rotation angle range due to the large volume of the energy storage capacitor 33.

[0188] As shown in Figure 1As shown, the light energy generating assembly 3 is located in the right angle space formed between the first adjusting member 21 and the second adjusting member 22, and during the horizontal rotation of the light energy generating assembly 3, the two sides of the light energy generating assembly 3 will interfere with the second adjusting member 22 in the vertical state, which will limit the rotation angle of the light energy generating assembly 3, so that the light energy generating assembly 3 can only rotate within the specific angle. Although narrowing the width of the light energy generating device can expand the specific angle, the light energy generating efficiency will be greatly reduced. The embodiment of the present application designs the shape of the shell assembly 35 to be thinner on both sides, so that the light energy generating assembly can rotate in a larger angle range under the premise of ensuring sufficient width, that is, the specific angle is expanded.

[0189] Further, as shown in Figure 3 and Figure 2 , the arch part 3511 extends towards the third direction, and since the third direction is in the same direction as the axial direction of the detection main body 1, the arch part 3511 will not affect the rotation angle range of the light energy generating assembly 3, and the internal space of the arch part 3511 can accommodate a larger energy storage capacitor 33.

[0190] Further, as shown in Figure 24 and Figure 23 , one end of the third circuit board 32 is welded with a USB plug, the USB plug protrudes from the shell assembly 35, and the USB plug and each energy storage capacitor 33 are arranged in a straight line in the third direction, so that part of the USB plug is located inside the arch part 3511. The USB plug is embedded in the third circuit board 32, so that the USB plug is located in the middle position of the end of the shell assembly 35, avoiding that the shell assembly 35 causes excessive shielding to the keys 1331 of the detection main body 1. As shown in Figure 22 , the end of the base shell 352 is provided with a USB through hole 3521, and during assembly, the USB plug is first inserted through the USB through hole 3521, then the third circuit board 32 is placed on the base shell 352, and finally the arch shell 351 is buckled on the base shell 352.

[0191] In some embodiments, as shown in Figure 23 , Figure 25 and Figure 28As shown, the arch part 3511 is provided with a test key 3512 and a light emitting hole 3513, the third circuit board 32 is provided with a detection switch 37 and a light emitting piece 38 at positions corresponding to the test key 3512 and the light emitting hole 3513 respectively, the test key can be pressed to trigger the detection switch 37, the light emitting piece 38 emits light in response to the detection switch 37 being triggered, the detection switch 37 and the light emitting piece 38 are both contained inside the arch part 3511, so that the detection switch 37 and the light emitting piece 38 do not cause the thickness of other parts of the shell assembly 35 to increase. Among them, the test key 3512 functions to detect whether the electric quantity of the energy storage capacitor 33 is greater than a certain value, the light emitting piece 38 adopts a blue LED lamp, the minimum voltage at which the blue LED lamp begins to emit light is 2.8V, when the voltage of the energy storage capacitor 33 is greater than 2.8V, the user presses the test key 3512 to light up the light emitting piece 38, and the voltage of the energy storage capacitor 33 can reflect the current storage capacity.

[0192] Further, the detection switch 37 adopts a tactile switch. As shown in Figure 22 、 Figure 23 and Figure 28 , the test key 3512 is connected to the arch part 3511 through a key 1331 arm, the extension direction of the key 1331 arm is parallel to the extension direction of the arch part 3511, and the test key 3512 and the key 1331 arm are integrally formed on the arch part 3511. Further, the outer surface of the arch part 3511 is flush with the outer surface of the test key 3512. Further, as shown in Figure 23 , the back of the test key 3512 is provided with a trigger protrusion for triggering the electronic switch 126.

[0193] Further, as shown in Figure 23 and Figure 25 , the light emitting hole 3513 extends downward around a light shielding ring, the lower end of the light shielding ring abuts against the third circuit board 32, a light shielding cavity 3514 is formed between the light shielding ring and the third circuit board 32, and the light emitting piece 38 is arranged inside the light shielding cavity 3514.

[0194] In some embodiments, as shown in Figure 22 , the third circuit board 32 is located between the base shell 352 and the arch shell 351, and the light energy plate 31 is located on the side of the base shell 352 away from the arch shell 351; the light energy plate 31 is bonded to the base shell 352, double-sided tape 39 is attached to the back of the light energy plate 31, and the light energy plate 31 is attached to the base shell 352 through the double-sided tape 39.

[0195] As shown in Figure 22As shown, the back of the light energy plate 31 is provided with a positive contact 312 and a negative contact 313, which are located at both ends of the light energy plate 31, and the double-sided adhesive tape 39 is cut blank at the positions corresponding to the positive contact 312 and the negative contact 313. Figure 26 and Figure 24 As shown, the third circuit is respectively provided with a spring conductive seat 322 abutting against the positive contact 312 and the negative contact 313, and the base shell 352 is provided with an opening allowing the spring conductive seat 322 to pass through the base shell 352 and abut against the positive contact 312 and the negative contact 313. The side of the base shell 352 facing the light energy plate 31 is provided with a mounting groove 3522, the size of which is adapted to the light energy plate 31, and the light energy plate 31 is embedded in the mounting groove 3522, and the double-sided adhesive tape 39 is attached to the bottom surface of the mounting groove 3522.

[0196] As shown, Figure 25 the third circuit board 32 is clamped and fixed by the base shell 352 and the arched shell 351; the base shell 352 is provided with four positioning ribs 3525 and a plurality of supporting ribs protruding towards the third circuit board 32, the four positioning ribs 3525 are inserted into the third circuit board 32 to position the third circuit board 32 in the horizontal direction, and the supporting ribs abut against the lower surface of the third circuit board 32; the arched shell 351 is provided with a plurality of pressing ribs 3515 facing the third circuit board 32, which abut against the upper surface of the third circuit board 32; and the base shell 352 is buckled on the arched shell 351, so that the third circuit board 32 is clamped and fixed by the base shell 352 and the arched shell 351.

[0197] Further, as shown, Figure 25 the arched shell 351 is provided with a plurality of first buckling buckles 3516 on both sides, and the base shell 352 is correspondingly provided with second buckling buckles 3523, the first buckling buckles 3516 are buckled on the second buckling buckles 3523 to realize the fixed connection of the arched shell 351 and the base shell 352. Among them, the arched shell 351 is provided with three first buckling buckles 3516 on both sides.

[0198] Further, as shown, Figure 26 , Figure 23 and Figure 28 the base shell 352 is provided with a containing through hole 3524 at the position corresponding to the energy storage capacitor 33, and part of the energy storage capacitor 33 is sunk into the containing through hole 3524. Thus, the thickness of the base shell 352 can be used to accommodate the energy storage capacitor 33, reducing the thickness occupied by the energy storage capacitor 33, thereby reducing the thickness of the shell assembly 35.

[0199] Further, as shown, Figure 23As shown, the inner side of the arched shell 351 is provided with a thinning groove 3517 at the position corresponding to the energy storage capacitor 33, which is used to thin the wall thickness of the arched shell 351, so as to accommodate a larger volume of the energy storage capacitor 33.

[0200] In another embodiment, as shown in the figure, Figure 29 the difference between this embodiment and the Figures 1-26 embodiment is that the plug part 34 of the light energy power generation assembly 3 is changed from a USB plug to a DC power plug, and the USB jack of the detection main body 1 is changed to a DC power jack. The advantage of this arrangement is that since the DC power plug is cylindrical, the light energy power generation assembly 3 can be rotated around the DC power plug after being plugged into the detection main body 1, so as to adjust the detection direction and the light energy receiving direction separately, so that the light energy receiving surface 311 is arranged towards the light source, thereby improving the power generation efficiency and more accurately controlling the detection range. The other structures of this embodiment are the same as those of the embodiment shown in the figure, and will not be described here. Figures 1-26

[0201] The existing human body sensor is installed with a compatible base, generally the keys and power interface are arranged on the side, once the base is installed in place, the keys and power interface are often blocked or close to the wall, resulting in inconvenient operation of the keys and power plug.

[0202] To solve the above problems, according to the second aspect of the present application, as shown in the figure, Figures 1-29 a human body detection device 100 is provided, wherein the structure of the human body detection device 100 is the same as that of the human body detection device 100 provided by the first aspect of the present application, and the technical details of the structure can be referred to the above description. As shown in the figure, Figure 1 and Figure 6 the human body detection device 100 comprises a detection main body 1 and an adjusting support 2, the adjusting support 2 comprises a first adjusting part 21 and a second adjusting part 22 rotatably connected to the first adjusting part 21, and the second adjusting part 22 is used to be connected to a mounting surface 200; the detection direction of the detection main body 1 is towards the side, the first adjusting part 21 is provided with a first clamping part 211, the bottom of the detection main body 1 is protrudingly provided with a second clamping part 132, the second clamping part 132 is embeddedly clamped to the first clamping part 211, and the second clamping part 132 can rotate based on the first clamping part 211; the second clamping part 132 is provided with an operation part 133, the operation part 133 is used to trigger an electronic switch 126 inside the detection main body 1 and / or connect a power supply device, and the operation part 133 is located on the bottom surface of the second clamping part 132, when the second clamping part 132 is embedded in the first clamping part 211, the operation part 133 is exposed to the outside through the first clamping part 211.

[0203] ​In a daily use scenario, the detection direction is generally adjusted to be horizontal. Since the detection direction of the detection main body 1 of the embodiment is towards the lateral direction, the bottom of the detection main body 1 is towards the downward direction in a normal use scenario, and the orientation of the bottom of the detection main body 1 is relatively stable regardless of the rotation of the detection direction. The operation part 133 (the key 1331 and / or the power supply interface) is arranged at the bottom of the detection main body 1, so that the operation part 133 is prevented from being close to the wall and exposed downward, thereby facilitating the operation of the key 1331 and the plug-in electrical interface 1332. When the operation part 133 is plugged with a power supply line, the power supply line is less likely to interfere with other components.

[0204] In addition, the second clamping part 132 is not only used for arranging the operation part 133, but also used for supporting the detection main body 1 and rotating the detection direction, so that the functions of supporting, adjusting and operating are integrated in one structure, thereby realizing high structural integration.

[0205] It is worth mentioning that when the second adjusting part 22 is installed on a horizontal plane, the second adjusting part 22 is folded with the first adjusting part 21, so that the operation part 133 is hidden between the first adjusting part 21 and the second adjusting part 22, thereby improving the integrity of the appearance.

[0206] Thanks to the cooperation of the double rotating shafts between the detection main body 1 and the second adjusting part 22, the detection main body 1 can be freely rotated in the horizontal and pitch directions, and the user can infinitely adjust the detection main body 1 to the best angle. When the user's adjustment operation is removed, the friction of the rotating shaft can support the detection main body 1 to maintain the current direction.

[0207] When the adjusting support 2 is pasted at a higher position or a relatively narrow position, it is more inconvenient to replace the button cell 15. Thanks to the fact that the second clamping part 132 is rotatably clamped to the first clamping part 211, the user can disassemble the detection main body 1 from the adjusting support 2, so as to more conveniently replace the button cell 15. When installing, no tools are needed. Only the second clamping part 132 needs to be embedded in the first clamping part 211, and the installation can be completed by hearing "click".

[0208] Further, as shown in Figure 6 the second clamping part 132 includes a circular boss 1321 and a plurality of circumferential buckles 1322 distributed on the side surface of the circular boss 1321, the first clamping part 211 includes a circular through hole 2111, the circular boss 1321 is embedded in the circular through hole 2111, and the circumferential buckles 1322 are clamped to the edge of the circular through hole 2111; the operation part 133 is located on the end surface of the circular boss 1321, and when the circular boss 1321 is embedded in the circular through hole 2111, the operation part 133 is exposed outward through the circular through hole 2111.

[0209] Further, the operation part 133 comprises a button 1331 and / or an electrical plug interface 1332.

[0210] Further, as shown in Figure 6 and Figure 11 , the detection main body 1 comprises a cylindrical shell 13, the circular boss 1321 is arranged at the bottom of the cylindrical shell 13, and the button 1331 is integrally connected to the cylindrical shell 13 through a connecting arm 134, when the first adjusting part 21 is clamped to the circular boss 1321, the first adjusting part 21 blocks the connecting arm 134.

[0211] In some embodiments, as shown in Figure 11 and Figure 1 , when the circumferential buckle 1322 is clamped to the circular through hole 2111, the circular boss 1321 does not protrude from the side of the first adjusting part 21 facing away from the detection main body 1.

[0212] Further, as shown in Figure 8 and Figure 6 , the first clamping part 211 further comprises an annular groove 2112 arranged around the circular through hole 2111, the annular groove 2112 is located at the end of the circular through hole 2111 away from the detection main body 1; the circumferential buckle 1322 is clamped to the annular groove 2112, and the circumferential buckle 1322 is accommodated in the annular groove 2112, so that the circular boss 1321 does not protrude from the side of the first adjusting part 21 facing away from the detection main body 1.

[0213] The adjusting bracket 2 described above can provide two adjustable rotation degrees of freedom, and the two rotation degrees of freedom cooperate with each other to allow the detection main body 1 to realize free rotation in the horizontal and pitch directions, as shown in Figure 9 , when the second adjusting part 22 is pasted on a vertical wall, the detection main body 1 is blocked by the wall, and only has a 90° adjustable range in the vertical direction, in combination with the 360° adjustable range of the detection main body 1 in the horizontal direction, the actual detection direction can only be adjusted in the second and fourth quadrants, and cannot achieve four-quadrant dead-angle-free adjustment.

[0214] To solve the above problems, in the embodiments of the present application, as shown in Figures 6-8As shown, the rotation axis of the detection body 1 relative to the first adjusting part 21 is the first rotation axis 23; the rotation axis of the second adjusting part 22 relative to the first adjusting part 21 is the second rotation axis 24; the second adjusting part 22 has a magnetic surface 2221 for rotatable magnetic connection to the mounting surface 200, the second rotation axis 24 is parallel to the magnetic surface 2221, and the first rotation axis 23 is perpendicular to the second rotation axis 24, so that there are three adjustable rotation degrees of freedom between the detection body 1 and the mounting surface 200. That is, in Figure 9 , the second adjusting part 22 can be rotated to fit the wall surface, and through the cooperation of the three rotation degrees of freedom, the detection direction can be adjusted without dead angle in the four quadrants.

[0215] It is worth noting that the detection area of the detection body 1 is not a symmetrical area up and down and left and right, but an irregular area with unequal horizontal width and vertical width. Through the cooperation of the three rotation degrees of freedom, the phase angle of the detection area can also be adjusted, so that the horizontal direction and the vertical direction of the detection area are rotated and transformed, thereby more accurately controlling the detection area. For example, as shown in Figure 9 , at this time, the second adjusting part 22 is rotated by 90° to fit the wall surface, although the detection direction does not change, but the horizontal direction and the vertical direction of the detection area are rotated and transformed, thereby changing the detection area.

[0216] In summary, through the cooperation of the three rotation degrees of freedom, the effect of adjusting the detection direction without dead angle and randomly transforming the phase angle of the detection area can be achieved.

[0217] Further, as shown in Figure 8 , the edge of the first adjusting part 21 is rotatably connected to the second adjusting part 22.

[0218] Further, as shown in Figure 8 , the edge of the first adjusting part 21 is provided with a connecting protrusion 212 protruding towards the second adjusting part 22, and the edge of the second adjusting part 22 is provided with a connecting groove 2211, one side wall of the connecting groove 2211 is provided with a convex shaft 2212, and the other side wall is provided with a connecting through hole; one side wall of the connecting protrusion 212 is provided with a clamping groove, and the other side wall is provided with a threaded hole 2213; the connecting protrusion 212 is embedded in the connecting groove 2211, the convex shaft 2212 is clamped into the clamping groove, and a screw 25 is connected to the threaded hole 2213 through the connecting through hole, so as to realize the rotatable connection between the first adjusting part 21 and the second adjusting part 22.

[0219] In some embodiments, as shown in Figure 8As shown, the second adjusting member 22 comprises a base 221 and a magnetic attracting member 222, the first adjusting member 21 is rotationally connected to the base 221, the magnetic attracting member 222 is embeddedly installed on a side of the base 221 which is away from the first adjusting member 21, and a side of the magnetic attracting member 222 which is away from the first adjusting member 21 forms the magnetic attracting surface 2221.

[0221] It should be further noted that the above embodiments can be combined with each other, and the same or similar concepts or processes may not be described in some embodiments, that is, the technical solutions disclosed in the latter embodiments (in the order of the text) should include the technical solutions disclosed in this embodiment and all the technical solutions in the previous embodiments.
