[0050] The following is combined with Figure 1-Figure 11 This application is described in further detail.

[0051] The embodiment of the present application discloses an induction switch 100 .

[0052] Reference Figure 1-Figure 3 According to the embodiment of the present application, the inductive switch 100 comprises: a housing 2, an inductive module 3, a metal panel 4 and a controller. The housing 2 comprises a front housing 21 and a rear housing 22, the rear housing 22 is adapted to be embedded in the mounting wall 1, the front housing 21 is mounted on the end wall of the rear housing 22 away from the mounting wall 1, the front housing 21 is connected and matched with the mounting wall 1, so that the inductive switch 100 is fixedly connected with the mounting wall 1, the front housing 21 defines a first mounting space 211, and the front housing 21 is adapted to allow electromagnetic signals to pass through.

[0053] In some specific embodiments, the installation wall surface 1 may be a wall surface, but the present application is not limited thereto, and the installation wall surface 1 may also be a desktop surface or the like.

[0054] Further, refer to Fig.11 When the installation wall surface 1 is a wall surface, the rear housing 22 is buried in the wall. In other specific embodiments, the user can directly bond the rear housing 22 to the installation wall surface 1, but the present application is not limited thereto. The user can also remove the rear housing 22 and directly bond the front housing 21 to the installation wall surface 1.

[0055] In some specific embodiments, the front housing 21 may be made of plastic, but the present application is not limited thereto, and the front housing 21 may also be made of materials such as glass.

[0056] The sensing module 3 is arranged in the front shell 21, and the sensing module 3 is used to transmit and receive electromagnetic signals. The metal panel 4 is arranged on the end wall of the front shell 21 away from the rear shell 22. The area of ​​the metal panel 4 is larger than the area of ​​the front shell 21. Specifically, the length dimension of the metal panel 4 is larger than the length dimension of the front shell 21, and the width dimension of the metal panel 4 is larger than the width dimension of the front shell 21. That is to say, the front shell 21 is completely covered by the metal panel 4, and the electromagnetic signal is blocked and reflected by the metal panel 4, so that the electromagnetic signal passes through the front shell 21.

[0057] Specifically, the end wall of the metal panel 4 away from the front shell 21 is suitable for being set opposite to the human body. After the electromagnetic signal emitted by the sensing module 3 is reflected by the metal panel 4, the electromagnetic signal passes through the front shell 21 and enters the external environment. Then, the electromagnetic signal is reflected by the installation wall 1 and propagates toward the end wall of the metal panel 4 away from the front shell 21.

[0058] When a human body passes through the sensing switch 100, the electromagnetic signal is reflected by the human body. The electromagnetic signal reflected by the human body is reflected by the installation wall 1 and passes through the front shell 21 into the sensing switch 100. The electromagnetic signal entering the sensing switch 100 is received by the sensing module 3, thereby achieving the technical effect of the sensing module 3 sensing whether the human body passes through the sensing switch 100.

[0059] It should be noted that when the electromagnetic signal propagates toward the end wall of the metal panel 4 away from the front housing 21 , the electromagnetic signal surrounds the outer side of the metal panel 4 in a ring shape, and the volume of the induction switch 100 is smaller than the volume of the human body.

[0060] In some specific embodiments, the electromagnetic signal may be a radar signal, but the present application is not limited thereto, and the electromagnetic signal may also be an electromagnetic wave, etc.

[0061] In addition, the controller is communicatively connected with the sensing module 3, and the controller is used to generate and send a control signal according to the electromagnetic signal received by the sensing module 3. Specifically, when the sensing module 3 receives the electromagnetic signal reflected by the human body, the sensing module 3 sends a sensing signal to the controller, and the controller generates a control signal according to the sensing signal of the sensing module 3. In some specific embodiments, the control signal can be used to control the turning on of the lamp, but the present application is not limited to this. The control signal can also be used to control the access unlocking or opening of the anti-theft door.

[0062] In some specific embodiments, the controller can be connected to the lamp for communication. When the controller generates a control signal, the controller controls the lamp to turn on according to the control signal so that the lamp can illuminate. It should be noted that when the lamp is turned on for a preset time, the lamp automatically turns off.

[0063] Thus, the electromagnetic signal is blocked and reflected by the metal panel 4 so that the electromagnetic signal passes through the front shell 21 and leaves the sensing switch 100, and the electromagnetic signal is reflected by the installation wall 1 so that the electromagnetic signal propagates toward the end wall of the metal panel 4 away from the front shell 21, and the electromagnetic signal detects whether a human body passes through the sensing switch 100. The electromagnetic signal reflected by the human body is reflected by the installation wall 1 and passes through the front shell 21 to be received by the sensing module 3. Compared with the prior art, the metal panel 4 does not need to be subjected to hole opening processing, thereby reducing the processing complexity of the metal panel 4 and protecting the appearance integrity of the metal panel 4.

[0064] Reference Figure 1-Figure 3 In some embodiments of the present application, the metal panel 4 includes a plurality of reflecting portions 41 and a connecting portion 42, the plurality of reflecting portions 41 are all arranged on the outer peripheral wall of the connecting portion 42, and the plurality of reflecting portions 41 are arranged in sequence along the circumferential direction of the connecting portion 42, that is, the connecting portion 42 is located in the central area of ​​the metal panel 4, the plurality of reflecting portions 41 are all located in the edge area of ​​the metal panel 4, and the plurality of reflecting portions 41 are arranged around the outer side of the connecting portion 42.

[0065] Furthermore, in a direction from the center to the edge of the connecting portion 42, the plurality of reflecting portions 41 are all inclined toward the rear housing 22. Specifically, Figure 2 In the embodiment shown, along the first direction of the induction switch 100 and along the height direction of the induction switch 100, the reflecting portion 41 located on the left side of the connecting portion 42 is tilted toward the lower left, and the reflecting portion 41 located on the right side of the connecting portion 42 is tilted toward the lower right. The first direction of the induction switch 100 can refer to Figure 2 The left and right directions in the figure, the height direction of the induction switch 100 can refer to Figure 2 The up and down directions in .

[0066] In addition, there is an angle between the multiple reflecting parts 41 and the front shell 21. The reflecting parts 41 are used to reflect electromagnetic signals. Specifically, a part of the electromagnetic signals emitted by the sensing module 3 is blocked and reflected by the connecting part 42. The electromagnetic signals blocked and reflected by the connecting part 42 gradually attenuate after multiple reflections in the sensing switch 100 along the vertical direction. Another part of the electromagnetic signals emitted by the sensing module 3 is reflected by the reflecting part 41. Through the angle between the reflecting part 41 and the front shell 21, the electromagnetic signals reflected by the reflecting part 41 pass through the front shell 21 and leave the sensing switch 100, thereby achieving the technical effect that the metal panel 4 reflects the electromagnetic signal so that the electromagnetic signal passes through the front shell 21 and enters the external environment.

[0067] It should be noted that the electromagnetic signal emitted by the sensing module 3 propagates toward the metal panel 4 in a hemispherical shape.

[0068] Reference Figure 2 , Figure 3 and Figure 5 In some embodiments of the present application, the induction switch 100 may further include: a control switch 5, a first installation space 211 forms an open opening 212 on the end wall of the front shell 21 close to the metal panel 4, the control switch 5 is arranged in the front shell 21, and the metal panel 4 is movably arranged on the front shell 21 and stops and cooperates with the control switch 5. Specifically, the trigger part of the control switch 5 passes through the open opening 212 and stops and cooperates with the end wall of the metal panel 4 close to the front shell 21.

[0069] In addition, the control switch 5 is communicatively connected with the sensing module 3. The control switch 5 is triggered when the metal panel 4 is pressed, so that the control switch 5 controls the sensing module 3 to turn on or off. Specifically, the user can press the metal panel 4 with the hand. After being pressed, the metal panel 4 moves close to the rear shell 22 and triggers the control switch 5. The control switch 5 controls the sensing module 3 to turn on, so that the sensing module 3 senses whether a human body passes through the sensing switch 100. When the user does not need the sensing switch 100 to sense the human body, the user can press the metal panel 4 again with the hand. The metal panel 4 triggers the control switch 5. The control switch 5 controls the sensing module 3 to turn off. The user can turn on or off the sensing module 3 through the control switch 5 according to the usage requirements of the sensing switch 100, thereby improving the usage experience of the sensing switch 100 and reducing the energy usage of the sensing switch 100.

[0070] It should be noted that, when the metal panel 4 triggers the control switch 5 , the control switch 5 can drive the metal panel 4 to move away from the rear housing 22 , so that the metal panel 4 is reset.

[0071] In some specific embodiments, the control switch 5 may be a micro switch, but the present application is not limited thereto, and the control switch 5 may also be a key switch or the like.

[0072] Further, refer to Fig.10 There can be multiple control switches 5, and the multiple control switches 5 are arranged in sequence along the circumferential direction of the front shell 21, and the multiple control switches 5 are all communicated with the sensing module 3. When one of the multiple control switches 5 is triggered, the triggered control switch 5 controls the sensing module 3 to turn on or off. By setting multiple control switches 5, the user can press any area of ​​the metal panel 4 to make the corresponding control switch 5 control the sensing module 3 to turn on or off.

[0073] Reference Figure 6 and Figure 7 In some embodiments of the present application, the front shell 21 includes a transparent member 213 and a limiting member 214. The transparent member 213 is connected and cooperated with the rear shell 22. The transparent member 213 defines a first installation space 211, and the transparent member 213 is suitable for allowing electromagnetic signals to pass through. The limiting member 214, the control switch 5 and the sensing module 3 are all arranged in the transparent member 213.

[0075] Specifically, when the metal panel 4 is installed on the front shell 21, the first clamping protrusion 431 and the first clamping recess 2142 are clamped and matched, and the stop portion 432 and the reset portion 2143 are stop-matched. When the metal panel 4 is pressed by the user, the metal panel 4 drives the clamping member 43 to move close to the rear shell 22, and the clamping member 43 drives the first clamping protrusion 431 to move close to the rear shell 22. The first clamping protrusion 431 is separated from the first clamping recess 2142, and the clamping member 43 drives the stop portion 432 to move close to the rear shell 22 at the same time. The reset portion 2143 is driven to bend and deform toward the direction of the rear shell 22. When the metal panel 4 is separated from the user, the reset portion 2143 drives the stop portion 432 to move away from the rear shell 22, and the stop portion 432 drives the snap-fit ​​component 43 and the metal panel 4 to move away from the rear shell 22, and the snap-fit ​​component 43 drives the first snap-fit ​​protrusion 431 to move away from the rear shell 22 and snap-fit ​​with the first snap-fit ​​recess 2142, thereby preventing the metal panel 4 from being separated from the front shell 21 and achieving the technical effect of the metal panel 4 being movably arranged on the front shell 21.

By arranging multiple first clamping protrusions 431 and multiple first clamping protrusions 431, the connection reliability between the clamping member 43 and the limiting member 214 can be improved. By arranging multiple stop portions 432 and multiple reset portions 2143, the multiple reset portions 2143 can evenly drive the metal panel 4 to move away from the rear shell 22.

[0077] Reference Figure 8 In some embodiments of the present application, a guide portion 44 is provided on the end wall of the metal panel 4 close to the rear shell 22, and a guide hole 433 is provided on the end wall of the clamping member 43 close to the metal panel 4.
