Only by obtaining accurate sensing results can reliable execution basis be provided for terminal devices in the intelligent scene.

[0003] The human presence sensor uses a radar detection module to actively emit radar detection waves and receive the reflected radar waves, and judges whether there is a moving human body or object in the detection area based on the Doppler principle.

For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0063] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. The technical solutions between the various embodiments can be combined with each other, but it must be based on the fact that those skilled in the art can implement them. When the combination of the technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.

[0064] At present, the surface-mounted human presence sensors on the market generally use screws to be directly fixed to the mounting surface. When the volume or weight of the sensor body is large, the difficulty of installation and disassembly will be greatly increased, bringing inconvenience to installation and disassembly.

[0065] To solve the problem of inconvenient installation and disassembly of the existing surface-mounted human presence sensors, according to the first aspect of the present utility model, a human detection device 100 is provided. Please refer to Figures 1 - 21, the human body detection device 100 provided by the present utility model will be specifically explained. The human body detection device 100 includes a connector 1, a housing 2, and a circuit module 3. The connector 1 is used to be installed on an external mounting surface 200; the housing 2 can move relative to the connector 1 to be installed on the connector 1, and can move relative to the connector 1 to be detached from the connector 1; the circuit module 3 is disposed in the housing 2, and the circuit module 3 includes a radar detection module 31. The radar detection module 31 can emit radar detection waves, and the radar detection waves are used to detect the presence of a human body. Among them, the circuit module 3 can be understood as the circuit part of the human body detection device 100, including a circuit board, electronic components, etc. The external mounting surface 200 can be understood as a surface in the environment that can be installed, which can be a wall surface, a door surface, a ceiling surface, a suspended ceiling board surface, etc. The movement of the housing 2 relative to the connector 1 can be a linear movement, a rotational movement, etc. In some exemplary embodiments, the movement direction of the housing 2 can be parallel to the external mounting surface 200 or perpendicular to the external mounting surface 200. In one embodiment, the radar detection module 31 selects a 24 GHz radar module. The radar detection module 31 actively emits radar detection waves externally and receives the reflected radar waves, and judges whether there is a moving human body or object in the detection area based on the Doppler principle.

[0066] Compared with the traditional human presence sensor that is integrally fixed to the external mounting surface 200 by screws, the housing 2 of this embodiment is installed on the external mounting surface 200 through the connector 1. Since the connector 1 is thinner, smaller and more compact, the difficulty for the user to install the connector 1 is lower; and the housing 2 is installed or detached from the connector 1 by movement, making the installation and detachment of the housing 2 more convenient, which is beneficial to the frequent disassembly and installation of the housing 2.

[0067] In some embodiments, as Figures 7 - 15 shown, the housing 2 can be rotatably connected to the connector 1 and can be rotatably detached from the connector 1. Among them, the rotational connection can be a rotational snap connection or the housing 2 is processed with threads and connected by threads, etc. In some embodiments, as Figures 7 - 14As shown, the connector 1 includes a circular connection body 11 and a plurality of rotary snap positions 12 distributed along the circumferential direction of the connection body 11. The rotary snap positions 12 extend along the circumferential direction of the connection body 11. The housing 2 is provided with a snap structure 21, and the snap structure 21 is rotatably snapped into the rotary snap positions 12, making the installation and disassembly of the housing 2 and the connector 1 faster and more convenient. Moreover, the use of the rotary snap connection method makes the connector 1 thinner, so that the radar detection module 31 can be closer to the external mounting surface 200 and has a wider detection range. Among them, the rotary snap connection can be understood as that the snap structure 21 can be snap-fitted into the rotary snap positions 12 through rotational movement. In addition, the snap structure 21 can be disengaged from the rotary snap positions 12 through rotational movement. The rotary snap positions 12 are provided with a limiting portion 123, and the limiting portion 123 is used to limit the snap structure 21 from disengaging from the rotary snap positions 12, making the connection between the housing 2 and the connector 1 more stable. Among them, the so-called "circular" can be understood as a disc shape, a circular ring shape or other similar circular shapes. The rotary snap positions 12 can be understood as structures adapted to the snap structure 21, such as snap holes, snap grooves, snap platforms, etc. Further, as Figures 1 - 3 shown, the housing 2 is an inverted structure similar to a round bowl shape, and the thin shell member 4 is a circular arc-shaped housing 2 structure. As Figure 8 shown, the thin shell member 4 covers the opening side of the housing 2 and forms a structure similar to a round cake shape with the housing 2.

[0068] In one embodiment, as Figures 7 - 10As shown, the connecting body 11 has an abutting surface 111, and the abutting surface 111 is used to abut against the housing 2. By abutting, the angular relationship between the housing 2 and the connector 1 is made more precise, so as to ensure that the detection direction of the radar detection module 31 is more accurate. Three first clamping walls 121 are evenly distributed along the circumferential direction of the connecting body 11. The first clamping walls 121 extend along the circumferential direction of the connecting body 11, and the first clamping walls 121 are used to clamp the housing 2. The first clamping wall 121 is configured as the bottom wall of the rotary clamping position 12, and the abutting surface 111 is the lower surface of the first clamping wall 121. A sunken groove 22 is provided at a position corresponding to the abutting surface 111 on the housing 2, and the connector 1 sinks into the sunken groove 22, thereby reducing the height of the connector 1 protruding from the housing 2 and making the gap between the housing 2 and the external mounting surface 200 smaller. The clamping structure 21 of the housing 2 includes second clamping walls 211 corresponding to the first clamping walls 121. The second clamping walls 211 protrude inward from the side walls of the sunken groove 22; the bottom surface of the sunken groove 22 abuts against the abutting surface 111, and there is a clamping gap between the bottom surface of the sunken groove 22 and the second clamping wall 211. When the housing 2 is rotatably clamped to the connector 1, the first clamping wall 121 is clamped in the clamping gap, the bottom surface of the sunken groove 22 abuts against the abutting surface 111, and the lower surface of the second clamping wall 211 abuts against the upper surface of the first clamping wall 121; wherein, the upper surface of the first clamping wall 121 is an inclined surface. During the rotation of the housing 2, the abutting force between the second clamping wall 211 and the first clamping wall 121 increases with the increase of the rotation angle, so that the connection between the first clamping wall 121 and the second clamping wall 211 is more stable.

[0069] Furthermore, the connecting body 11 includes a first wall 112 parallel to the abutting surface 111. The first wall 112 is arranged above the first clamping wall 121, and a rotary clamping position 12 is formed between the first clamping wall 121 and the first wall 112; one end of the rotary clamping position 12 is provided with an end wall 122, and the end wall 122 connects the first wall 112 and the first clamping wall 121. The end wall 122 is used to limit the limit position of the rotational movement of the second clamping wall 211; a limiting portion 123 is arranged on one side of the first clamping wall 121 facing the abutting surface 111, and the limiting portion 123 is used to limit the clamping structure 21 from disengaging from the rotary clamping position 12. In this embodiment, the limiting portion 123 is configured as a convex rib, and the second clamping wall 211 is limited between the limiting portion 123 and the end wall 122, making the connection between the housing 2 and the connector 1 more stable.

[0070] Furthermore, as Figure 9As shown, the connector 1 is fixedly connected to the external mounting surface 200 by a plurality of screws. The first wall 112 is configured as an annular plate-like structure, and its center is concentric with the center of the housing 2. The first wall 112 protrudes toward the external mounting surface 200 and is provided with a plurality of support protrusions 1121. The support protrusions 1121 are evenly distributed along the circumferential direction of the first wall 112. When the connector 1 is fixedly connected to the external mounting surface 200, the support protrusions 1121 abut against the external mounting surface 200 to prevent the first wall 112 from deforming under the action of the screw tightening force, ensuring that the first wall 112 is parallel to the external mounting surface 200, and further preventing the position of the rotary snap position 12 from being affected by the screw tightening force.

[0071] In some embodiments, as Figure 15 shown, a snap groove 124 and a snap-in port 125 are formed on one side of the connection body 11 facing the housing 2. The snap groove 124 extends arc-shaped along the circumferential direction of the connection body 11. The snap-in port 125 is provided at the end of the snap groove 124. The width of the snap-in port 125 is greater than the width of the snap groove 124. The housing 2 is provided with a snap structure 21. The snap structure 21 is rotatably snapped into the snap groove 124 from the snap-in port 125. Further, the number of the snap grooves 124 is three, and the three snap grooves 124 are evenly distributed along the circumferential direction of the connection body 11. The snap groove 124 is configured as an arc-shaped strip hole, and the snap-in port 125 is configured as a circular hole. The snap structure 21 includes three snap protrusions 212. The positions of the snap protrusions 212 correspond to the snap grooves 124. The snap protrusion 212 includes a connection column extending upward from the housing 2 and a snap cap provided at the upper end of the connection column. The width of the connection column is slightly smaller than the width of the snap groove 124 so that the connection column can slide in the snap groove 124. The diameter of the snap cap is greater than the width of the snap groove 124 and smaller than the width of the snap-in port 125. The snap cap is snapped upward into the snap-in port 125 and then rotatably snapped into the snap groove 124. Since the diameter of the snap cap is greater than the width of the snap groove 124, the snap cap cannot be disengaged from the snap groove 124 downward. A limiting recess 126 is provided at one end of the snap groove 124 away from the snap-in port 125. The limiting recess 126 is provided on the upper surface of the connector 1 and is shaped to fit the snap cap. When the snap cap moves to the position where the limiting recess 126 is located, the snap cap sinks into the limiting recess 126, making it difficult for the snap cap to disengage from the limiting recess 126, so as to increase the connection stability between the snap protrusion 212 and the snap groove 124.

[0072] In some embodiments, as Figure 20 and Figure 21The housing 2 can be slidably connected to the connector 1 and can be slidably removed from the connector 1. The sliding connection can be a matching connection between the slide groove 23 and the slide rail or other sliding connection methods. The advantage of using a sliding connection is that the housing 2 will not rotate in the horizontal direction during the sliding process. This connection method is more suitable for square housings and can ensure that the installation direction of the square housing is horizontal and vertical. In one embodiment, Figures 20 - 21 As shown, the connector 1 includes a connecting body 11 and sliding parts 13 respectively arranged on both sides of the connecting body 11, and the housing 2 is provided with a slide groove 23 adapted to the sliding part 13, and the sliding part 13 slides into the slide groove 23 so that the housing 2 is connected to the connector 1. The sliding part 13 can be a structure such as a slide rail, a slide bar, a buckle, etc. In one embodiment, the sliding part 13 is configured as a slide bar, and the extension direction of the slide bar is the same as that of the slide groove 23. The connecting body 11 is a rectangular plate-like structure, and the slide bar protrudes horizontally and is arranged on both sides of the connecting body 11. There are two slide grooves 23, and the two slide grooves 23 are respectively located at the corresponding positions of the two slide bars, and the opening directions of the two slide grooves 23 are arranged oppositely, and the thickness of the slide groove 23 is adapted to the slide bar, and the slide bar slides horizontally into the slide groove 23 so that the housing 2 cannot be separated from the connector 1 downward. One end of the slide slot 23 is open, and the other end is provided with a stop corner 231. The slide bar slides into the open end of the slide slot 23 and stops when it slides to the stop corner 231. Figure 21 As shown, three waist-shaped holes 14 are respectively opened on the left and right sides of the connector 1 , and the three waist-shaped holes 14 on the same side are arranged side by side. The connector 1 is installed and fixed to the outside through the waist-shaped holes 14 .

[0073] In this embodiment, if Figure 16 and Figure 17 As shown, the shell 2 is a rectangular cover-like structure with an open lower side, and the thin shell 4 is a rectangular shell 2 slightly convex downward, and the thin shell 4 is arranged on the open side of the shell 2. Figure 20 As shown, a side transparent member 25 is provided on the side of the housing 2 away from the thin shell member 4. The side transparent member 25 is light-transmissive and has a rectangular ring shape and is inclined to the upper surface of the housing 2. The side transparent member 25 transmits the light in the accommodating cavity to illuminate the external mounting surface 200 around the human body detection device 100. Figure 17 As shown, the housing 2 is provided with a plurality of light-transmitting holes 27 at positions corresponding to the side transparent member 25, and the light-transmitting holes 27 are arranged around the housing 2. Furthermore, the side transparent member 25 and the thin shell member 4 are respectively connected to the housing 2 by buckles.

[0074] In some embodiments,Figure 9 Figure 13 、 Figure 15 and Figure 21 As shown in Figure 21 , a wire passing portion 113 is provided in the connection body 11. The wire passing portion 113 penetrates through the connection body 11 for wires to pass through, facilitating wiring and enabling the wires to be hidden inside the connector 1. Further, a wire through hole 24 is provided in the housing 2, and the wire passes through the wire passing portion 113 and the housing 2 and is connected to the circuit module 3. Further, as Figure 7 、 Figure 9 and Figure 15 As shown in Figure 15 , a rubber sealing ring is snap - fitted inside the wire through hole 24 of the housing 2. The rubber sealing ring is sleeved on the wire, making the seal between the wire and the wire through hole 24.

[0075] In some embodiments, the connector 1 is disposed on the upper side of the housing 2 so that the human body detection device 100 is suitable for ceiling mounting; the ratio of the thickness to the width of the connector 1 is less than 1 / 5. When the housing 2 is mounted on the connector 1 and the connector 1 is mounted on the external mounting surface 200, the connector 1 is hidden between the housing 2 and the external mounting surface 200, so that the distance between the housing 2 and the external mounting surface 200 is smaller, the mounting position is more flexible, and it can ensure that the detection direction of the radar detection module 31 is perpendicular to the external mounting surface 200, making it easier for the user to control the detection direction; at the same time, the ceiling - mounted visual effect of the human body detection device 100 can be achieved. Among them, the fact that the connector 1 is hidden does not mean that the connector 1 is completely covered, but should be understood as when the human body detection device 100 is ceiling - mounted on the ceiling or the suspended ceiling board, the user cannot see the connector 1 when viewing from the perspective of standing on the ground. The ratio of the thickness to the width of the connector 1 being less than 1 / 5 can not only make the distance between the housing 2 and the external mounting surface 200 smaller, but also be conducive to the connector 1 being hidden between the housing 2 and the external mounting surface 200. Further, as Figure 9 As shown in Figure 9 , a sunken groove 22 is provided on the upper surface of the housing 2, and a part of the connector 1 sinks into the sunken groove 22, thereby reducing the height of the connector 1 protruding from the housing 2 and making the gap between the housing 2 and the external mounting surface 200 smaller. As Figure 8 As shown in Figure 8 , the gap between the housing 2 and the external mounting surface 200 is set as L1, the horizontal width of the housing 2 is set as L2, and the horizontal width of the connector 1 is set as L4 (not marked in the figure). In this embodiment, by controlling the thickness of the connector 1 and the depth of the sunken depression to control L1, such that L1 / L2 < 1 / 50 and L4 / L2 < 2 / 3, thereby ensuring the concealment of the connector 1 to achieve the ceiling - mounted visual effect of the human body detection device 100.

[0076] In some embodiments, asFigures 1 - 4 As shown, one end of the housing 2 facing away from the connector 1 is open, and a thin shell member 4 is provided at the open end of the housing 2. The thin shell member 4 and the housing 2 form a receiving cavity, and the circuit module 3 is received inside the receiving cavity. The radar detection module 31 has a transmitting surface 311, and the transmitting surface 311 faces the thin shell member 4. The transmitting surface 311 can emit the radar detection wave, and the radar detection wave passes through the thin shell member 4 and is emitted externally. Wherein, the transmitting surface 311 faces the thin shell member 4, that is, the transmitting surface 311 faces away from the connector 1. When the connector 1 is installed on the external mounting surface 200, it can ensure that the detection direction of the radar detection module 31 is perpendicular to the external mounting surface 200, so that the detection direction is easier to control. The thickness of the thin shell member 4 is relatively thin, which is beneficial to the radar detection wave passing through, thereby reducing the loss of the radar detection wave.

[0077] In some embodiments, as Figure 5 、 Figure 4 and Figure 8 shown, the circuit module 3 includes a first circuit board 32, a second circuit board 33, a third circuit board 34 and a wireless communication module 35. The first circuit board 32 is disposed on the housing 2, and the first circuit board 32 is used to arrange the high-voltage circuit and is electrically connected to the light-emitting member; the second circuit board 33 is mounted on the first circuit board 32 through the first row of pins 331; the third circuit board 34 is mounted on the second circuit board 33 through the second row of pins 341, and the radar detection module 31 is disposed on the third circuit board 34; so that the height of the radar detection module 31 is raised, and the transmitting surface 311 can be higher than the electronic components on the first circuit board 32, avoiding the radar detection wave emitted by the transmitting surface 311 being reflected by the electronic components to cause interference; the wireless communication module 35 is disposed on the second circuit board 33 and is located between the third circuit board 34 and the second circuit board 33. The wireless communication module 35 and the radar detection module 31 are stacked up and down, which can improve the space utilization rate, reduce the area of the first circuit board 32, and enable the second circuit board 33, the third circuit board 34, the radar detection module 31 and the wireless communication module 35 to form a general module, which can be directly used in other models of the human body detection device 100, and the pin connection belongs to the standardized connection method, which can facilitate the welding or insertion of the general module on the circuit board of other devices. Further, the first row of pins 331 is connected to the first end of the second circuit board 33, and the second row of pins 341 is connected to the end of the second circuit board 33 away from the first end.

[0078] Further, as Figure 5As shown, a support foam 327 is pasted on the first circuit board 32. The support foam 327 abuts against one side of the second circuit board 33 facing the first circuit board 32, and the support foam 327 is arranged at one end of the second circuit board 33 away from the first row of pins 331, for supporting the second circuit board 33 to keep the second circuit board 33 in a horizontal state.

[0079] In another embodiment, as Figure 25 shown, the wireless communication module 35 can also be directly arranged on the first circuit board 32. The third circuit board 34 is directly mounted on the first circuit board 32 through the second row of pins 341. The radar detection module 31 is arranged on the third circuit board 34, and the wireless communication module 35 is located between the first circuit board 32 and the third circuit board 34.

[0080] In some embodiments, as Figures 1 - 7 and Figures 16 - 21 shown, the connector 1 is arranged on the upper side of the housing 2 so that the housing 2 can be top-mounted; the thin shell member 4 is made of a light-transmitting material and formed. A light-emitting member 5 is arranged inside the accommodation cavity, and the light emitted by the light-emitting member 5 is emitted outward through the thin shell member 4; the light-emitting member 5 is electrically connected to the radar detection module 31 and can switch the working state in response to the detection result of the radar detection module 31. Wherein, the light-emitting member 5 is used for lighting. In one embodiment, the light-emitting member 5 includes a plurality of light-emitting units 52, and the light-emitting unit 52 is preferably an LED lamp bead. The thin shell member 4 is made of a light-transmitting material and has a light homogenizing effect, making the light emitted outward more uniform and the lighting effect better. In one embodiment, the thin shell member 4 is integrally formed of acrylic material. The switching of the working state can be switching the switch state or adjusting the brightness, color temperature, etc.

[0081] In one embodiment, as Figure 2 and Figure 3 shown, to adapt to the circular housing 2, the light-emitting member 5 includes 4 conductive strips 51, and a plurality of light-emitting units 52 are arranged on each conductive strip 51. The 4 conductive strips 51 are connected end to end and enclose a quadrilateral, and the circuit module 3 is surrounded in the center by the quadrilateral. A triangular fixing frame 53 is arranged at the connection part between each conductive strip 51. The fixing frame 53 is used to fix the conductive strip 51 to the housing 2 and maintain the electrical connection state between the conductive strips 51. The conductive strip 51 is connected to the circuit module 3 through a wire, and a wire pressing member 26 is arranged between the conductive strip 51 and the circuit module 3. The wire pressing member 26 fixes the wire to the housing 2.

[0082] In another embodiment, as Figure 17As shown, the housing 2 is adapted to the rectangular shape, and the light-emitting member 5 includes 8 conductive strips 51 arranged in parallel, each conductive strip 51 is fixed to the housing 2 by a hot-melt riveting column 29, and the hot-melt riveting column 29 is integrally formed in the housing 2. Among them, the arrangement direction of the conductive strips 51 is the long side direction of the rectangular housing 2, and a plurality of light-emitting units 52 are arranged on each conductive strip 51. The first circuit board 32 is arranged between the two conductive strips 51 in the middle, and the first circuit board 32 is in the shape of a long strip. The first circuit board 32 and the conductive strips 51 are arranged in parallel to reduce the light blocking of the circuit module 3. The conductive strips 51 are connected by wires, and the two conductive strips 51 adjacent to the first circuit board 32 are respectively connected to the first circuit board 32 by wires.

[0083] In some embodiments, Figure 7 As shown, a side transparent member 25 is provided on the side of the housing 2 away from the thin shell member 4. The side transparent member 25 is light-transmissive and has a ring shape and is inclined to the upper surface of the housing 2. The side transparent member 25 transmits the light in the accommodating cavity to illuminate the external mounting surface 200 around the human body detection device 100. Figure 3 As shown, the housing 2 is provided with a plurality of light-transmitting holes 27 at positions corresponding to the side transparent member 25, and the light-transmitting holes 27 are arranged around the housing 2. Furthermore, the side transparent member 25 and the thin shell member 4 are respectively connected to the housing 2 by buckles.

[0084] Furthermore, if Figure 4 and Figure 18 As shown, the third circuit board 34 is provided with a light sensing module 342, and the light sensing module 342 can sense light illumination. The ambient light outside the human body detection device 100 is irradiated to the light sensing module 342 through the thin shell 4, so that the light sensing module 342 senses the ambient light illumination, so that the light-emitting component 5 can switch the working state according to the ambient light illumination. In one embodiment, the light sensing module 342 is configured as a photoresistor. Furthermore, the second circuit board 33 is provided with two LED indicator lights 332, and the LED indicator lights 332 are used to indicate the working state of the human body detection device 100. The light emitted by the LED indicator lights 332 is displayed to the outside through the thin shell 4.

[0085] Furthermore, if Figures 3 - 5As shown, two mounting through-holes 321 are formed in the first circuit board 32, and positioning through-holes 322 are respectively arranged near each mounting through-hole 321. Threaded connection holes are arranged at the corresponding positions of each mounting through-hole 321 on the housing 2, and positioning posts are arranged at the corresponding positions of each positioning through-hole 322. The positioning posts are inserted into the positioning through-holes 322 to position the first circuit board 32, and the mounting through-holes 321 are fixedly connected to the threaded connection holes by screws. A power supply module and a driving module are arranged on the first circuit board 32. The power supply module is used to access the mains circuit and convert 220V industrial frequency alternating current into direct current for subsequent circuits to use; the driving module is used to drive the light-emitting component 5 to switch the working state. Two first welding holes 323 for connecting household alternating current and three second welding holes 324 for connecting the light-emitting component 5 are arranged on the first circuit board 32. Among them, the first circuit board 32 is square, and the first welding holes 323 and the second welding holes 324 are respectively located at the diagonals of the first circuit board 32.

[0086] In the existing ceiling-mounted human detection device with a lighting function, the radar detection module is generally arranged outside the housing. The patent with the application number 202222985729.1 discloses a microwave sensor and its housing. Among them, the microwave sensor is snap-connected to the upper surface of the lamp board, and lamp beads are arranged on the lower surface of the lamp board. To prevent the microwaves emitted by the microwave sensor from being blocked by the lamp board, the lamp board is provided with a mounting hole, and the detection protrusion of the microwave sensor passes through the mounting hole and protrudes from the lower surface of the lamp board. The advantage of this setting is that the detection protrusion occupies a small area of the lamp board, the main body of the microwave sensor is arranged on the lamp board, which is convenient for the microwave sensor to be independently wired, and the microwave sensor is snap-connected to the lamp board, which is convenient for installation and disassembly. However, the microwave sensor occupies the space above the lamp board, resulting in a large distance between the lamp board and the ceiling board, making it difficult to achieve the effect of ceiling installation. Moreover, since the lamp board is provided with a mounting hole for the detection protrusion of the microwave sensor to pass through, the sealing performance of the lamp board is poor.

[0087] To avoid the radar detection module 31 occupying the space above the lamp board and improve the sealing performance of the lamp board, according to the second aspect of the present invention, as Figures 1 - 29As shown in the figure, a human body detection device 100 is provided, which includes a housing 2, a light-emitting component 5, a thin shell component 4, and a circuit module 3. The housing 2 is used for external installation. The thin shell component 4 covers the housing 2 and forms a receiving cavity with the housing 2. The light-emitting component 5 is arranged inside the receiving cavity, and the light emitted by the light-emitting component 5 is emitted outward through the thin shell component 4. The circuit module 3 is arranged inside the receiving cavity. The circuit module 3 includes a first circuit board 32 and a radar detection module 31 electrically connected to the first circuit board 32. The light-emitting component 5 is electrically connected to the first circuit board 32. The radar detection module 31 has a transmitting surface 311, and the transmitting surface 311 is arranged facing the thin shell component 4. The transmitting surface 311 can emit radar detection waves, and the radar detection waves pass through the thin shell component 4 and are emitted outward for detecting whether there is a human body in a region. The light-emitting component 5 switches its working state in response to the detection result of the radar detection module 31. Among them, the technical details of the housing 2, the thin shell component 4, the light-emitting component 5, the circuit module 3, and the radar detection module 31 are described in detail above and will not be elaborated here. In the present utility model, the radar detection module 31 is integrated inside the receiving cavity, avoiding occupying the space above the housing 2, making the distance between the housing 2 and the external installation surface 200 smaller. Thus, when the human body detection device 100 is installed on the ceiling, the effect of ceiling-mounted installation can be achieved. Additionally, since the radar detection module 31 is arranged inside the housing 2, there are no extra openings on the upper surface of the housing 2 except for the wire holes, and the sealing performance is better.

[0088] Furthermore, since the circuit module 3 is integrated inside the housing 2, the light-emitting component 5 can be directly connected to the circuit module 3. The circuit module 3 is integrated with a driving module to enable the circuit module 3 to directly drive the light-emitting component 5 to work based on the electrical connection, improving the response speed. The circuit module 3 is integrated with a power module. When wiring, connecting the circuit module 3 to the household alternating current can complete the wiring, without the need to additionally connect a power supply or a driver, which is convenient and fast.

[0089] Among them, Figures 1 - 15 The illustrated embodiment provides a circular human body detection device 100 that can be connected to an external installation surface 200 such as a ceiling board or a wall through the connector 1; Figures 16 - 21 The illustrated embodiment provides a rectangular human body detection device 100, and its installation method is the same as that of the circular human body detection device 100; Figures 22 - 29 The illustrated embodiment provides a rectangular flat human body detection device 100 that can be snap-fitted and installed on a keel frame, and its installation method is the same as that of an aluminum gusset plate.

[0090] Furthermore, the light emitted by the light-emitting component 5 is evenly distributed by the thin shell component 4 and then diverges outward. Since the circuit module 3 is arranged inside the housing 2 and the volume of the circuit module 3 is relatively large, it will block and reflect the light, resulting in poor light homogenization effect of the thin shell component 4. Through prototype testing, the R & D personnel found that a shadow will appear at the position of the thin shell component 4 directly opposite to the circuit module 3. To solve the shadow caused by the circuit module 3, the R & D personnel made the following improvements:

[0091] First, as Figure 8 shown, the radar detection module 31 is directly or indirectly mounted on the first circuit board 32, and the vertical distance L3 between the emission surface 311 and the thin shell component 4 is greater than 18 mm. Herein, the vertical distance can be understood as the distance between the emission surface 311 and the thin shell component 4 in the direction perpendicular to the emission surface 311, and the L3 is marked in Figure 8 . In this embodiment, by increasing the vertical distance between the emission surface 311 and the thin shell component 4, the emission surface 311 is prevented from casting a shadow on the thin shell component 4. In addition, to prevent the radar detection wave emitted by the radar detection module 31 from being interfered by electronic components, in this embodiment, the radar detection module 31 is mounted on the first circuit board 32, and it is ensured that the distance between the emission surface 311 and the first circuit board 32 is greater than 5 mm, so as to achieve a balance between detection performance and shadow elimination. Further, as Figure 6 shown, the radar detection module 31 is arranged on the third circuit board 34, and the third circuit board 34 is sleeved with a white heat-shrinkable sleeve 371 to reduce the shadow by reflecting light through the heat-shrinkable sleeve 371. The third circuit board 34 is mounted on the second circuit board 33 through the second row of pins 341, and the second circuit board 33 is mounted on the first circuit board 32 through the first row of pins 331. The technical details of the third circuit board 34, the second circuit board 33, and the first circuit board 32 are described in detail above and will not be elaborated here.

[0092] To further reduce the shadow generated by the circuit module 3, as Figure 17 shown, a receiving groove 281 is recessed on the surface of the housing 2 facing the thin shell component 4, and the first circuit board 32 is received in the receiving groove 281. Thus, the height of the circuit module 3 protruding from the housing 2 is reduced, and the shadow generated by the circuit module 3 on the thin shell component 4 is reduced. Further, as Figure 20 and Figure 21As shown, a protruding portion 282 is provided at a position corresponding to the accommodation groove 281 on the top of the housing 2, and the shape of the protruding portion 282 matches that of the accommodation groove 281; the height of the protruding portion 282 is lower than the thickness of the connector 1 to avoid affecting the installation of the connector 1. The technical details of the connector 1 are described in detail above and will not be elaborated here. Further, a wire through-hole 24 is provided on the side surface of the protruding portion 282, and the wire through-hole 24 penetrates through the housing 2 for wires to pass through.

[0093] Further, as Figure 17 , Figure 28 and Figure 6 shown, the human body detection device 100 further includes a covering member 37, and at least part of the circuit module 3 is wrapped or covered by the covering member 37 to prevent the electronic components from casting shadows or variegated colors on the thin shell member 4. The covering member 37 is preferably white so as to be able to reflect white light, thereby reducing the shadows. Herein, the at least part can be understood as part or all of the parts.

[0094] Further, as Figure 28 and Figure 6 shown, the covering member 37 is configured as a white heat-shrinkable tube 371, and at least part of the circuit module 3 is sleeved by the heat-shrinkable tube 371 to eliminate shadows by reflecting light through the white heat-shrinkable tube 371. Among them, in the embodiment shown in Figure 28 , the circuit module 3 is in a long strip shape, and almost the entire circuit module 3 is sleeved by the heat-shrinkable tube 371. In the embodiment shown in Figure 6 , only the third circuit board 34 is sleeved by the heat-shrinkable tube 371, and the radar detection module 31 is arranged within the sleeved range of the heat-shrinkable tube 371. In one embodiment, as Figure 27 shown, the size of the housing 2 is approximately 300 mm × 300 mm, the light-emitting member 5 includes 4 conductive strips 51 arranged in parallel, and a plurality of light-emitting units 52 are arranged on each conductive strip 51. The light-emitting units 52 are preferably LED lamp beads. The conductive strips 51 are riveted and fixed to the housing 2 through hot-melt riveting posts 29. Specifically, as Figure 27 and Figure 25As shown, the hot melt riveting post 29 is integrally formed on the housing 2. The conductive strip 51 is provided with a riveting hole 325 at a position corresponding to the hot melt riveting post 29. After the hot melt riveting post 29 passes through the riveting hole 325, the end of the hot melt riveting post 29 is flattened after heating, so as to rivet and fix the conductive strip 51. Among them, the circuit module 3 is arranged between the two conductive strips 51 in the middle. The circuit module 3 is strip-shaped, and the circuit module 3 is arranged side by side with the conductive strip 51 to reduce the light shielding of the circuit module 3. The conductive strips 51 are connected to each other by wires (not shown in the figure), and the two conductive strips 51 adjacent to the first circuit board 32 are respectively connected to the first circuit board 32 by wires (not shown in the figure).

[0095] In another embodiment, as Figure 29 shown, the size of the housing 2 is about 300mm×600mm. The light emitting member 5 includes 4 conductive strips 51 arranged side by side. A plurality of light emitting units 52 are arranged on each conductive strip 51. The light emitting unit 52 is preferably an LED lamp bead. Among them, the extending direction of the conductive strip 51 is parallel to the long side direction of the housing 2, and the arrangement direction is parallel to the short side direction of the housing 2. The circuit module 3 is arranged between the two conductive strips 51 in the middle. The circuit module 3 is strip-shaped, and the circuit module 3 is arranged side by side with the conductive strip 51 to reduce the light shielding of the circuit module 3. The length of the circuit module 3 is about half of that of the conductive strip 51. The radar detection module 31 is arranged at the end of the circuit module 3, and the radar detection module 31 is located at the middle position of the housing 2. The circuit module 3 in this embodiment is the same as Figure 27 the circuit module 3 in the embodiment.

[0096] In some embodiments, as Figure 27 and Figure 29 shown, the light emitting member 5 includes 4 conductive strips 51 arranged side by side. The circuit module 3 is arranged side by side with the conductive strip 51. The circuit module 3 is arranged between the two middle conductive strips 51. Among them, the distance between the two conductive strips 51 adjacent to the circuit module 3 is greater than the distance between the two conductive strips far from the circuit module 3, so that there is enough distance between the circuit module 3 and the conductive strip 51 to reduce the light shielding of the circuit module 3, thereby avoiding the circuit module 3 from generating shadows on the thin shell member 4.

[0097] In some embodiments, as Figure 28As shown, riveting holes 325 are respectively formed at both ends and the middle position of the first circuit board 32. The riveting holes 325 are riveted to the hot melt riveting posts 29. The heat shrinkable sleeve 371 has two sections, which are respectively sleeved on the left and right sections of the circuit module 3, so that the riveting hole 325 in the middle is exposed for hot melt riveting. After the heat shrinkable sleeve 371 is sleeved on the circuit module 3, the heat shrinkable sleeve 371 is heated, so that the heat shrinkable sleeve 371 shrinks and tightly adheres to the circuit module 3 (as shown in Figure 28 the bottommost figure). In Figure 6 the shown embodiment, after the heat shrinkable sleeve 371 is sleeved on the third circuit board 34, the heat shrinkable sleeve 371 is heated, so that the heat shrinkable sleeve 371 shrinks and tightly adheres to the third circuit board 34.

[0098] As Figure 28 shown in the first figure, a first inductor 3261 is arranged on the first circuit board 32. Since the volume of the first inductor 3261 is relatively large, it is easy to block light, resulting in a shadow of the first inductor 3261 on the thin shell part 4, and it is also difficult for the heat shrinkable sleeve 371 to be sleeved on the first inductor 3261, further deepening the shadow. To reduce the shadow brought by the first inductor 3261, as Figure 28 shown in the second figure, the first inductor 3261 is split into two second inductors 3262 connected in series with each other. The two second inductors 3262 are arranged along the long side direction of the first circuit board 32, and the two second inductors 3262 are centered in the short side direction of the first circuit board 32; at the same time, the heat shrinkable sleeve 371 sleeves the second inductors 3262 to reduce the shadow generated by the second inductors 3262 on the thin shell part 4. Further, one of the riveting holes 325 on the first circuit board 32 is arranged between the two second inductors 3262.

[0099] Further, as Figure 28 shown, two first welding holes 323 for connecting household alternating current are formed at one end of the first circuit board 32 away from the radar detection module 31. The first circuit board 32 is respectively provided with a second welding hole 324 for connecting the light-emitting part 5 on both sides of the first cylindrical capacitor 3263. When the heat shrinkable sleeve 371 is sleeved on the circuit module 3, the wire connecting the second welding hole 324 passes out from the end of the heat shrinkable sleeve 371.

[0100] In some embodiments, as Figure 28 and Figure 6 shown, the circuit module 3 includes a light sensing module 342. The light sensing module 342 can sense the illuminance. The light sensing module 342 is arranged within the sleeved range of the heat shrinkable sleeve 371, so that the illuminance received by the light sensing module 342 is weakened, and further the detected illuminance range of the light sensing module 342 is increased. Specifically, asFigure 30 As shown, it is a graph of the R & D personnel measuring the voltage of the light sensor module 342 changing with the illuminance in the laboratory. It can be seen from the graph that when the light sensor module 342 is not sleeved with the heat shrinkable tube 371, the light sensor module 342 is more sensitive to light within the illuminance range of 400 LUX. Within this range, the voltage-illuminance curve is an inclined straight line, and the light sensor module 342 can detect the illuminance more accurately. When the illuminance is greater than 400 LUX, the sensitivity of the light sensor module 342 decreases, and the voltage-illuminance curve is an approximately horizontal straight line. At this time, it is difficult for the light sensor module 342 to accurately detect the illuminance. When the light sensor module 342 is sleeved with the heat shrinkable tube 371, the light sensor module 342 is more sensitive to light within the illuminance range of 3300 LUX. Within this range, the voltage-illuminance curve is an inclined straight line, and the light sensor module 342 can detect the illuminance more accurately. That is, when the light sensor module 342 is arranged within the sleeved range of the heat shrinkable tube 371, it can effectively increase the illuminance range detected by the light sensor module 342.

[0101] In some embodiments, as Figure 25 shown, the first circuit board 32 is provided with a first cylindrical capacitor 3263. The conductive column of the first cylindrical capacitor 3263 is bent so that the extending direction of the first cylindrical capacitor 3263 forms an angle less than 20° with the first circuit board 32, that is, the first cylindrical capacitor 3263 is laid flat to reduce the height of the first cylindrical capacitor 3263, avoid the first cylindrical capacitor 3263 casting a shadow on the thin shell member 4, and at the same time, avoid the first cylindrical capacitor 3263 interfering with the radar detection module 31. In a preferred embodiment, the extending direction of the first cylindrical capacitor 3263 is parallel to the first circuit board 32.

[0102] Furthermore, as Figure 23 shown, a ripple removal circuit and an AC-DC constant current conversion circuit are provided on the first circuit board 32. The ripple removal circuit includes a MOS transistor 3264. The ripple removal circuit achieves the purpose of removing ripples by frequently turning on and off the MOS transistor 3264. However, a large amount of heat is generated during the frequent on-off process of the MOS transistor 3264. To improve the heat dissipation rate of the MOS transistor 3264, the AC-DC constant current conversion circuit includes a relatively large-volume cylindrical capacitor 3263. The side surface of the first cylindrical capacitor 3263 abuts against the MOS transistor 3264 so that the MOS transistor 3264 dissipates heat through the first cylindrical capacitor 3263. Further, a thermal conductive silicone grease is provided between the MOS transistor 3264 and the first cylindrical capacitor 3263 to improve the heat conduction rate. Further, the first cylindrical capacitor 3263 is an electrolytic capacitor.

[0103] Furthermore, as Figure 27As shown, the first circuit board 32 is strip-shaped, the extending direction of the first circuit board 32 is parallel to the direction of the conductive strip 51 of the light-emitting component 5, the extending direction of the first cylindrical capacitor 3263 is the same as that of the first circuit board 32, and the first cylindrical capacitor 3263 is arranged at the middle position of the first circuit board 32 in the width direction to further avoid the first cylindrical capacitor 3263 generating a shadow.

[0104] In some embodiments, as Figure 17 shown, the covering member 37 is configured as a cover structure 372, the cover structure 372 covers the side of the circuit module 3 facing the thin shell member 4, and the circuit module 3 is covered by the cover structure 372 to prevent the electronic components from casting shadows or variegated colors on the thin shell member 4. The cover structure 372 can be understood as a structure including a top wall, peripheral side walls and an open bottom. In this embodiment, the covering member 37 is configured as a strip-shaped cover structure 372. Both ends of the cover structure 372 are fixedly connected to the housing 2 by screws. Positioning grooves 3721 are provided on both sides of the cover structure 372, and positioning protrusions 283 are provided on the housing 2 at positions corresponding to the positioning grooves 3721. The positioning protrusions 283 are embedded in the positioning grooves 3721 for positioning the cover structure 372 and strengthening the side wall strength of the cover structure 372. Two notches are provided at one end of the cover structure 372, and the wires of the light-emitting component 5 pass through the notches into the interior of the cover structure 372. The cover structure 372 is preferably white to facilitate light reflection. In one embodiment, the cover structure 372 is injection-molded from a white translucent material because, as Figure 18 shown, the third circuit board 34 is provided with a light-sensing module 342 for sensing the ambient light intensity. The ambient light passes through the thin shell member 4 and the cover structure 372 and irradiates the light-sensing module 342. The second circuit board 33 is provided with an LED indicator 332, and the light emitted by the LED indicator 332 passes through the cover structure 372 and the thin shell member 4 and is externally displayed. Therefore, to ensure the working performance of the light-sensing module 342 and the LED indicator 332, the cover structure 372 is made of a white translucent material.

[0105] Further, the surface of the first circuit board 32 facing the thin shell member 4 is made white so that the first circuit board 32 can reflect light and reduce the shadow generated by the circuit module 3. Further, the surfaces of the second circuit board 33 and the electronic components are also made white. Among them, the surfaces of the circuit board and the electronic components can be made white by spraying, pasting a white film or other means. Further, as Figure 17As shown, the first circuit board 32 is provided with a power module. The power module adopts a Boost boost circuit, which can boost 220V alternating current to 380V, thereby increasing the output power. The Boost boost circuit includes a boost inductor 36, and a white film is pasted on the surface of the boost inductor 36 to reflect light and avoid generating shadows. Further, the driving module includes a dimming circuit. When only having the brightness adjustment function, the dimming circuit can be composed of a single driving chip 3265 (such as a constant current dimming chip). When having both dimming and color adjustment functions, the dimming circuit can be composed of two driving chips 3265. Among them, the driving chip 3265 adopts the buck LED constant current dimming principle and is used in combination with a storage inductor 3267. In one embodiment, the driving module includes two storage inductors 3267, and a white film is pasted on the surface of the storage inductor 3267 to avoid generating shadows.

[0106] In some embodiments, as Figures 1 - 8 shown, the shapes of the housing 2 and the thin shell member 4 are both circular. The thin shell member 4 has a light-emitting surface, and the light emitted by the light-emitting member 5 diverges outward through the light-emitting surface. The light-emitting surface is configured as a convex arc surface. The circuit module 3 is disposed at the corresponding position in the center of the light-emitting surface, so that the vertical distance between the circuit module 3 and the thin shell member 4 is larger, thereby reducing the shadow generated by the circuit module 3.

[0107] In some embodiments, as Figure 17 shown, the shape of the housing 2 is rectangular. The light-emitting member 5 includes a plurality of conductive strips 51 arranged in parallel, and light-emitting units 52 disposed on each of the conductive strips 51. The first circuit board 32 is in a long strip shape and is arranged in parallel with the conductive strips 51. Among them, the technical details of the light-emitting member 5 and the housing 2 are described in detail above and will not be elaborated here. Further, the radar detection module 31 is disposed at the end of the first circuit board 32 to reduce the interference of electronic components on the radar detection module 31. Further, as Figures 17 - 18 shown, two first welding holes 323 for connecting household alternating current are provided on the first circuit board 32, and six second welding holes 324 for connecting the light-emitting member 5 are provided. The first welding holes 323 are disposed at one end of the first circuit board 32 far from the radar detection module 31, and the second welding holes 324 are disposed at one end of the first circuit board 32 close to the radar detection module 31. Among them, the six second welding holes 324 are divided into two groups and are respectively connected to the conductive strips 51 on the left and right sides of the circuit module 3.

[0108] In some embodiments, as Figure 19 and Figure 18As shown, the driving module includes two driving chips 3265. The driving chip 3265 is used to adjust the brightness and color temperature of the light-emitting element 5. Since the driving chip 3265 generates a large amount of heat, in this embodiment, a heat sink 3266 is attached to the upper surface of the driving chip 3265. The heat sink 3266 is welded to the first circuit board 32. Thermal grease is applied between the heat sink 3266 and the driving chip 3265 to improve the heat conduction rate. The heat sink 3266 has two upwardly tilted heat sink fins to improve the heat dissipation effect. Furthermore, the heat sink 3266 is formed by cutting and bending an iron sheet.

[0109] As a common connection structure, the buckle structure has many advantages, making it widely used in many fields such as industrial design, daily necessities, and electronic products. Its advantages mainly lie in: fast assembly and disassembly, low manufacturing cost, lightweight, good reusability, and smooth and neat appearance. However, its easy disassembly also brings problems: users can disassemble the shell at will to destroy the internal structure, disassemble the shell and reinstall it to destroy the sealing, and criminals can disassemble the shell and steal or tamper with the internal data.

[0110] In order to solve the problem of easy disassembly of the buckle structure, according to the third aspect of the utility model, please refer to Figures 22 - 24 , providing a buckling structure 6, such as Figure 24 As shown, the buckle structure 6 includes a first clip 61 and a second clip 62, wherein the first clip 61 is provided with at least one first clip 611, and the second clip 62 is provided with at least one second clip 621, wherein the first clip 611 is clipped to the second clip 621; the first clip 61 is provided with a reinforcing portion 612, wherein the reinforcing portion 612 abuts against a side of the second clip 621 away from the first clip 611, so as to prevent the second clip 621 from deforming in a direction away from the first clip 611, and prevent the second clip 621 from being disengaged from the first clip 611, thereby preventing the buckle structure 6 from being disassembled. The reinforcing portion 612 may be a reinforcing wall, a reinforcing rib, a protruding structure, etc., and the function of the reinforcing portion 612 is to strengthen the anti-deformation ability of the second clip 621. The anti-disassembly buckling structure 6 provided by the utility model not only has the characteristics of quick installation, low manufacturing cost, light weight, and smooth and neat appearance of ordinary buckles, but also has an anti-disassembly function, which can effectively prevent the shell 2 using the buckling structure 6 from being disassembled.

[0111] It is worth mentioning that since the buckle structure 6 provided by the utility model does not need to consider whether it is easy to disassemble, the researchers can design the buckle to have a greater snapping force during design, so that the sealing performance between the two components connected by the buckle structure 6 is better.

[0112] Further, as Figure 24 shown, the first clamping member 61 includes a support wall 613, the first buckle 611 is disposed on the support wall 613, a connecting wall 614 is disposed between the support wall 613 and the reinforcing portion 612, and an operation hole 615 is formed in the connecting wall 614 at a position corresponding to the first buckle 611. Wherein, the connecting wall 614 makes the connection between the reinforcing portion 612 and the first buckle 611 more stable, thereby making the reinforcing effect of the reinforcing portion 612 better, and the anti-deformation effect of the second buckle 621 is better. The operation hole 615 is used for maintenance personnel to insert a screwdriver to pry open the second buckle 621 destructively when necessary, forcing the second buckle 621 to separate from the first buckle 611, so as to disassemble the housing 2. After disassembly, the housing 2 cannot be used twice, and the maintenance personnel need to replace the new housing 2 for installation.

[0113] Further, as Figure 24 and Figure 22 shown, the width of the operation hole 615 is greater than the width of the first buckle 611, so that a screwdriver can be inserted into the operation hole 615 to smoothly pry open the second buckle 621.

[0114] Further, as Figure 24 shown, the reinforcing portion 612 is configured as a reinforcing wall, the side surface of the reinforcing wall abuts against the second buckle 621, and the support wall 613, the connecting wall 614 and the reinforcing wall surround the second buckle 621, so that the second buckle 621 and the first buckle 611 are stably clamped together. It is not easy for the user to separate the two buckles by prying the second buckle 621 or the support wall 613 where the first buckle 611 is located, thereby making the anti-disassembly performance of the buckling structure 6 stronger.

[0115] Further, as Figure 24 shown, the second clamping member 62 is provided with a recessed portion 622 at a position corresponding to the reinforcing wall, and the end of the reinforcing wall sinks into the recessed portion 622, so that it is not easy to insert a screwdriver into the end of the reinforcing wall, enhancing the anti-disassembly performance of the buckling structure 6.

[0116] In some embodiments, as Figure 24As shown, the first buckle 611 includes a first engaging surface, and the second buckle 621 includes a second engaging surface. When the first buckle 611 is engaged with the second buckle 621, the first engaging surface fits against the second engaging surface. Among them, the second engaging surface is disposed on a side of the second buckle 621 away from the operation hole 615, that is, the first buckle 611 is far from the operation hole 615, and the second buckle 621 is close to the operation hole 615. When a screwdriver is inserted into the operation hole 615, it will first contact the second buckle 621. When the user is not clear about the internal structure, the user will preferentially pry the second buckle 621, so that the anti-disassembly function of the second buckle 621 comes into play.

[0117] In some embodiments, as Figure 24 and Figure 22 shown, the number of the first buckles 611 is multiple, the second buckle 621 is configured as a whole, the second buckle 621 extends in the arrangement direction toward the first buckle 611, and each of the first buckles 611 is respectively engaged with the second buckle 621. Among them, the second buckle 621 is configured as a whole, further enhancing the anti-deformation ability of the second buckle 621 and making the anti-disassembly performance of the fastening structure 6 better. The reinforcing wall, the support wall 613, the connecting wall 614, and the second buckle 621 all extend along the arrangement direction of the first buckle 611.

[0118] According to the fourth aspect of the present invention, as Figures 22 - 29As shown in the figure, a flat panel lamp is provided, which includes the snap-fit structure 6 provided in the third aspect of the present invention. It further includes a housing 2, a profile frame 7, and a thin shell member 4. The housing 2 is configured as a lid-like structure with an open bottom, and the first snap-fit member 61 is integrally formed around its perimeter. Among them, the lid-like structure can be understood as a structure including a top wall and side walls around the perimeter and an open bottom. In this embodiment, the housing 2 includes a square top wall and four trapezoidal side walls provided around the square top wall. The trapezoidal side walls are inclined with respect to the vertical direction, and the four trapezoidal side walls enclose each other. The first snap-fit member 61 is provided at the bottom edge of the trapezoidal side wall, and the first snap-fit member 61 extends along the bottom edge of the trapezoidal side wall. The profile frame 7 is configured as a frame structure, and the second snap-fit member 62 is integrally formed around its perimeter. The profile frame 7 is sleeved on the bottom edge of the trapezoidal side wall, and the second snap-fit member 62 around the profile frame 7 is snap-fitted to the first snap-fit member 61 of the housing 2. The thin shell member 4 is provided at the bottom of the housing 2, and together with the housing 2, it forms a receiving cavity. A light-emitting member 5 is provided inside the receiving cavity, and the light emitted by the light-emitting member 5 is emitted outward through the thin shell member 4. A limiting wall 71 extends inward from the bottom of the profile frame 7, and the limiting wall 71 abuts against the lower surface of the thin shell member 4. The first snap-fit member 61 abuts against the upper surface of the thin shell member 4, and the thin shell member 4 is clamped and limited between the first snap-fit member 61 and the limiting wall 71. Among them, the flat panel lamp is the human body detection device 100 described above. The technical details of the light-emitting member 5, the housing 2, and the thin shell member 4 are described in detail above and will not be elaborated here. In this embodiment, the thin shell member 4 is configured as a rectangular thin plate structure.

[0119] In this embodiment, since the flat panel lamp has relatively high requirements for sealing performance, if dust or moisture enters the interior of the housing 2, it will affect the light-emitting effect and reduce the service life of the light-emitting lamp. Therefore, this embodiment adopts a non-detachable snap-fit structure 6 to ensure the sealing performance of the housing 2. Since the non-detachable snap-fit structure 6 does not need to consider the issue of easy disassembly, the R & D personnel can design the snap-in force of the snap to be greater during design, so that the pressing force between the housing 2, the profile frame 7, and the thin shell member 4 is greater and the sealing performance is better.

[0120] It is worth noting that Figures 22 - 27 A flat panel lamp with a specification of 300mm × 300mm is provided. Figure 29 A flat panel lamp with a specification of 300mm × 600mm is provided. The two specifications of flat panel lamps only differ in length, and other structures are the same. Among them, Figure 29 the thin shell member 4 in

[0121] Further, as shown in Figure 26 and Figure 29As shown, the limiting wall 71 surrounds the inner side of the profile frame 7 for one week, and the first clamping member 61 surrounds the edge of the housing 2 for one week. The first clamping member 61 presses and fits the four peripheral edges of the thin shell member 4 against the housing 2, so that there is a seamless fit between the thin shell member 4 and the housing 2, thereby improving the sealing performance of the flat lamp.

[0122] Further, as shown in Figure 23 , Figure 26 and Figure 27 , the flat lamp includes a circuit module 3 disposed inside the accommodation cavity. The circuit module 3 includes a radar detection module 31. The emission surface 311 of the radar detection module 31 faces the thin shell member 4. The emission surface 311 of the radar detection module 31 can emit radar detection waves. The radar detection waves pass through the thin shell member 4 and are emitted externally for detecting whether there is a human body in a region. Among them, the technical details of the circuit module 3 and the radar detection module 31 are described in detail above and will not be elaborated here. It is worth mentioning that since the water film has an obvious attenuation effect on the radar detection waves, a non-detachable fastening structure 6 is adopted between the housing 2 and the profile frame 7 in this embodiment, so that the sealing performance between the housing 2 and the thin shell member 4 is better, and dust and water vapor are prevented from entering the interior of the housing 2 and affecting the detection performance of the radar detection module 31.

[0123] During decoration, in order to ensure stability and safety, many household appliances and home devices need to be installed on the wall or ceiling by drilling holes. For example, TV brackets, audio equipment, lamps, curtain tracks, water heaters, bathroom hardware, etc. If there is a deviation in the drilling position, it will cause some household appliances to be installed unstably or even unable to be installed, and re-drilling will further damage the wall and increase the repair difficulty. The mounting brackets of existing home devices often use two circular holes to be installed on the wall, and the installation is fixed by the two-hole positioning method. Although the installation stability is good, this undoubtedly requires a high drilling accuracy. Even a slight deviation in the drilling position may result in the inability to install. If two kidney-shaped holes are used for installation, although the drilling accuracy requirements can be reduced, the connection stability is insufficient. Specifically, after the mounting bracket is locked to the wall surface by screws, the screws can still slide in the strip-shaped holes, causing the mounting bracket to slip or rotate, and the position of the mounting bracket cannot be locked.

[0124] To solve the problems of excessive requirements for drilling accuracy or insufficient connection stability of the above-mentioned mounting bracket, according to the fifth aspect of the present invention, as shown in Figures 9 - 15As shown, a connector 1 is provided, which includes a connection body 11 and a connection portion provided on the connection body 11, and the connection portion can be connected to a working body. Among them, the connection body 11 is provided with a first elongated hole 114, a second elongated hole 115, and a third elongated hole 116 for external installation. The extending direction of the first elongated hole 114 is the same as that of the second elongated hole 115, and there is a preset included angle between the extending direction of the first elongated hole 114 and the extending direction of the third elongated hole 116, and the preset included angle is between 70° and 110°. Among them, the working body can be understood as a functional component, such as the main body of a TV set, the lamp body of a ceiling lamp, the main body of a water heater, the main body of a human presence sensor, etc. The connector 1 can be understood as a connection component adapted to the working body, and the connector 1 is used to install the working body on a wall surface, the surface of a ceiling board, or other installation surfaces. The connection method between the connection portion and the working body can be screw fixed connection, snap connection, threaded fit connection, rotary snap connection, or other connection methods. The elongated holes include waist-shaped holes 14, rectangular holes, etc., and the extending direction of the elongated holes can be understood as the length direction of the elongated holes. The extending direction of the first elongated hole 114 being the same as that of the second elongated hole 115 can be understood as that the two are arranged in parallel or collinearly. The preset included angle being between 70° and 110° can be understood as that the extending direction of the first elongated hole 114 is approximately perpendicular (including perpendicular) to the extending direction of the third elongated hole 116.

[0125] The connector 1 provided by the present utility model uses three elongated holes for external installation, and the extending directions of the three elongated holes cooperate with each other so that when the drilling accuracy is not high, the connector 1 can be smoothly and stably fixed to the installation surface, avoiding the situation of unable to install or insufficient connection stability. The specific principle is as follows: Figures 10 - 12 Taking the shown embodiment as an example, the extending direction of the first elongated hole 114 is the same as that of the second elongated hole 115, and the extending direction of the first elongated hole 114 is perpendicular to the extending direction of the third elongated hole 116. As Figure 11 A first installation method is provided. As can be seen from the first figure of Figure 11 , at the corresponding positions of the first elongated hole 114, the second elongated hole 115, and the third elongated hole 116 on the installation surface, a first installation hole 210, a second installation hole 220, and a third installation hole 230 are respectively provided, but the position accuracy of the drilling is poor. When the first elongated hole 114 is aligned with the first installation hole 210, both the second installation hole 220 and the third installation hole 230 deviate from the ideal position. First, a first screw can be inserted into the first installation hole 210, and the first screw positions the first elongated hole 114; subsequently, the connector 1 is rotated around the first installation hole 210, as Figure 11As shown in the second figure, the second mounting hole 220 reaches within the second strip-shaped hole 115. At this time, the second screw can be inserted into the second mounting hole 220, and the second screw positions the second strip-shaped hole 115. Neither the first screw nor the second screw is tightened. Next, the connector 1 is translated along the extending direction of the first mounting hole 210, as Figure 11 shown in the third figure, such that the third mounting hole 230 reaches within the third strip-shaped hole 116. During the translation process, since the extending direction of the second mounting hole 220 is the same as that of the first mounting hole 210, the first screw and the second screw do not interfere with the translation of the connector 1. Finally, the third screw is inserted into the third mounting hole 230, and the third screw positions the third strip-shaped hole 116. Since the extending direction of the third strip-shaped hole 116 is perpendicular to the extending direction of the first strip-shaped hole 114, the third mounting hole 230 and the first mounting hole 210 jointly restrict the freedom of movement of the connecting member, while the first mounting hole 210 and the second mounting hole 220 jointly restrict the freedom of rotation of the connecting member. Therefore, the connector 1 cannot move or rotate under the positioning action of the three screws. At this time, the three screws are tightened, and the connector 1 will be completely locked. It realizes that when the drilling accuracy is not high, the connector 1 can also be smoothly and stably fixed to the mounting surface. In addition, the connector 1 is fixed by three screws, and the stability is higher.

[0126] Such as Figure 12 Provide a second installation method. As Figure 12 shown in the first figure, when the second strip-shaped hole 115 is aligned with the second mounting hole 220, both the first mounting hole 210 and the third mounting hole 230 deviate from the ideal positions. First, the second screw can be inserted into the second mounting hole 220, and the second screw positions the second strip-shaped hole 115. Subsequently, the connector 1 is rotated around the second mounting hole 220, as Figure 12 shown in the second figure, such that the first mounting hole 210 reaches within the first strip-shaped hole 114. At this time, the first screw can be inserted into the first mounting hole 210, and the first screw positions the first strip-shaped hole 114. Neither the first screw nor the second screw is tightened. Next, the connector 1 is translated along the extending direction of the second mounting hole 220, as Figure 12 shown in the third figure, such that the third mounting hole 230 reaches within the third strip-shaped hole 116. During the translation process, since the extending direction of the first mounting hole 210 is the same as that of the second mounting hole 220, the first screw and the second screw do not interfere with the translation of the connector 1. Finally, the third screw is inserted into the third mounting hole 230, and the third screw positions the third strip-shaped hole 116. At this time, the three screws are tightened, and the degrees of freedom of the connector 1 will be completely locked.

[0127] Furthermore, as Figure 11 and Figure 12As can be seen from the two installation methods shown, during the process of adjusting the position of the connector 1, there is a crucial step, namely rotational adjustment. It can be seen that if the extending direction of the first connection hole or the second connection hole is perpendicular to the direction of rotational adjustment, the adjustment range will be large; if the extending direction of the first connection hole or the second connection hole is parallel to the direction of rotational adjustment, the adjustment range will be small. Therefore, in this embodiment, as Figures 10 - 12 shown, the second elongated hole 115 is arranged in the extending direction of the first elongated hole 114, so that during rotational adjustment, the extending direction of the first connection hole or the second connection hole is perpendicular to the rotational direction, increasing the range of rotational adjustment, and thus having a higher tolerance for drilling deviation.

[0128] Furthermore, from Figure 11 it can be seen that the first mounting hole 210 and the second mounting hole 220 jointly restrict the rotational freedom of the connecting member, and the third mounting hole 230 and the first mounting hole 210 jointly restrict the translational freedom of the connecting member. Therefore, in this embodiment, the preset included angle is set to 90°, so that the third mounting hole 230 is perpendicular to the first mounting hole 210, making the restriction of the translational freedom of the connecting member more stable.

[0129] In some embodiments, as Figures 13 - 14 shown, the connection body 11 is provided with a fourth elongated hole 117, and the fourth elongated hole 117 is arranged parallel to the first elongated hole 114, that is, the connector 1 is provided with three parallel elongated holes and one perpendicular elongated hole, and the user can select two parallel elongated holes and one perpendicular elongated hole for installation according to requirements, with higher installation flexibility. In one embodiment, as Figure 14 shown in the first figure, the mounting surface is respectively provided with a second mounting hole 220, a third mounting hole 230 and a fourth mounting hole 240 at positions corresponding to the second elongated hole 115, the third elongated hole 116 and the fourth elongated hole 117, but the position accuracy of drilling is poor. When the second elongated hole 115 is aligned with the second mounting hole 220, both the third mounting hole 230 and the fourth mounting hole 240 deviate from the ideal position. First, the second screw can be inserted into the second mounting hole 220, and the second screw positions the second elongated hole 115; then, the connector 1 is rotated around the second mounting hole 220, as Figure 14 shown in the second figure, so that the fourth mounting hole 240 reaches into the fourth elongated hole 117. At this time, the fourth screw can be inserted into the fourth mounting hole 240, and the fourth screw positions the fourth elongated hole 117, and neither the second screw nor the fourth screw is tightened; next, the connector 1 is translated along the extending direction of the second mounting hole 220, as Figure 14As shown in the third figure, the third mounting hole 230 reaches inside the third elongated hole 116. During the translation process, since the extending direction of the fourth mounting hole 240 is the same as that of the second mounting hole 220, the fourth screw and the second screw will not interfere with the translation of the connector 1. Finally, insert the third screw into the third mounting hole 230, and the third screw positions the third elongated hole 116. Since the extending direction of the third elongated hole 116 is perpendicular to that of the second elongated hole 115, the third mounting hole 230 and the second mounting hole 220 jointly restrict the translational degree of freedom of the connecting member, while the second mounting hole 220 and the fourth mounting hole 240 jointly restrict the rotational degree of freedom of the connecting member. Therefore, the connector 1 cannot move or rotate under the positioning action of the three screws. At this time, lock the three screws, and the connector 1 will be completely locked.

[0130] In some embodiments, as Figure 9 and Figure 14 shown, the connection body 11 is provided with a wire passing portion 113. The wire passing portion 113 penetrates through the connection body 11 for wires to pass through. The wire passing portion 113 not only facilitates wiring but also can hide the wires inside the connector 1. A circuit module 3 is arranged inside the housing 2, and the wires pass through the wire passing portion 113 and the housing 2 and are connected to the circuit module 3.

[0131] In some embodiments, as Figures 9 - 15 shown, the connection portion is configured to be rotatably clamped to the working body. The connection body 11 is configured as a structure similar to a disc shape. The connection portion includes a plurality of rotation clamping positions 12 distributed along the circumferential direction of the connection body 11, and the rotation clamping positions 12 extend along the circumferential direction of the connection body 11. The rotation clamping can be understood as that the working body can be clamped and matched with the connection portion through a rotational movement. In addition, the working body can be disengaged from the connection portion through a rotational movement. Among them, thanks to the connector 1 being stably restricted in the rotational degree of freedom in the horizontal direction by three screws, it is avoided that the connector 1 loosens during the rotational clamping process of the working body, so that the working body can be rotatably clamped or rotatably separated stably and reliably. The technical details of the rotation clamping position 12 are described in detail above and will not be elaborated here.

[0132] Furthermore, as Figure 9 and Figure 10As shown, the connection body 11 has an abutting surface 111 for abutting against the working body; the connecting portion includes a first clamping wall 121 extending along the circumferential direction of the connection body 11 for clamping the working body, and the first clamping wall 121 is configured as the bottom wall of the rotary clamping position 12. Further, the connection body 11 includes a first wall 112 parallel to the abutting surface 111, and the first clamping wall 121 sinks below the first wall 112, and a rotary clamping position 12 is formed between the first clamping wall 121 and the first wall 112; the first wall 112 is configured as an annular plate-like structure, and a plurality of support protrusions 1121 are convexly provided on a surface of the first wall 112 facing away from the first clamping wall 121. The support protrusions 1121 are evenly distributed along the circumferential direction of the first wall 112. When the connector 1 is fixedly connected to the external mounting surface 200, the support protrusions 1121 abut against the external mounting surface 200 to prevent the first wall 112 from deforming under the action of the screw tightening force, ensure that the first wall 112 is parallel to the external mounting surface 200, and further prevent the position of the rotary clamping position 12 from being affected by the screw tightening force. Further, an end wall 122 is provided at one end of the rotary clamping position 12, and the end wall 122 connects the first wall 112 and the first clamping wall 121 for limiting the limit position of the rotational movement of the clamping structure 21 of the working body; a limiting portion 123 is provided on a side of the first clamping wall 121 facing the abutting surface 111 for limiting the clamping structure 21 of the working body from disengaging from the rotary clamping position 12. Among them, the technical details of the connection body 11, the first clamping wall 121, the first wall 112, the limiting portion 123, and the clamping structure 21 are described in detail above and will not be elaborated here.

[0133] In some embodiments, as Figure 15 shown, the connection body 11 is provided with a clamping groove 124 and a clamping inlet 125. The clamping groove 124 extends arcuately along the circumferential direction of the connection body 11, and the clamping inlet 125 is provided at an end of the clamping groove 124. The width of the clamping inlet 125 is greater than the width of the clamping groove 124, and the clamping inlet 125 is for the clamping structure 21 of the working body to be clamped into the clamping groove 124; the clamping groove 124 and the clamping inlet 125 form the rotary clamping position 12. Among them, the technical details of the clamping groove 124, the clamping inlet 125, and the clamping structure 21 are described in detail above and will not be elaborated here.

[0134] According to the sixth aspect of the present invention, as Figures 1 - 15 shown, a ceiling lamp is provided, including Figures 9 - 15The connector 1 shown, wherein the ceiling lamp further includes a lamp body, the lamp body is rotationally clamped to the connecting portion, and the lamp body includes: a housing 2, a thin shell member 4, and a light-emitting member 5. The housing 2 is provided with a clamping structure 21 adapted to the connecting portion, and the clamping structure 21 is rotationally clamped to the connecting body 11; the thin shell member 4 covers the side of the housing 2 facing away from the connecting body 11 and forms an accommodating cavity with the housing 2; the light-emitting member 5 is disposed inside the accommodating cavity, and the light emitted by the light-emitting member 5 is emitted outward through the thin shell member 4. Among them, the ceiling lamp is the human body detection device 100 described above, and the technical details of the housing 2, the thin shell member 4, and the light-emitting member 5 are described in detail above and will not be repeated here. Thanks to the connector 1 being stably restricted from rotating freely in the horizontal direction by three screws, it is avoided that the connector 1 loosens during the rotational clamping process of the working body, so that the lamp body can be rotationally clamped or rotationally separated stably and reliably.

[0135] Further, as Figures 2 - 5 shown, the lamp body includes a circuit module 3 disposed inside the accommodating cavity. The circuit module 3 includes a radar detection module 31, and the emission surface 311 of the radar detection module 31 faces the thin shell member 4. The emission surface 311 of the radar detection module 31 can emit radar detection waves, and the radar detection waves pass through the thin shell member 4 and are emitted outward for detecting whether there is a human body in a region. Among them, the technical details of the circuit module 3 and the radar detection module 31 are described in detail above and will not be repeated here. Thanks to the ceiling lamp being connected to the connector 1 by a rotational clamping method, the thickness of the connector 1 can be made very thin, thereby realizing the ceiling mounting of the lamp body, and the radar detection module 31 is closer to the ceiling board, making the detection range larger.

[0136] In addition, it should be noted that the above embodiments can be combined with each other. For the same or similar concepts or processes, they may not be repeated in some embodiments. That is, the technical solutions disclosed in the subsequent (in the order of recording in the text) embodiments should include the technical solutions recorded in this embodiment and the technical solutions in all the embodiments before this embodiment.
