Optionally, the control circuit 80 is configured to send an alarm prompt sound. Optionally, the control circuit 80 is configured to send an alarm prompt light. Optionally, the control circuit 80 is configured to send an alarm signal.

[0041] In particular, in combination with Figure 5 and Figure 6 As shown, the wireless transceiver 100 comprises a housing 40, a movable body 50, an elastic member 60, and a magnetic sensitive member 70. The housing 40 is provided with opposite main face 401 and back face 402. The movable body 50 is movably connected to the housing 40. The movable body 50 is at least partially magnetic. The movable body 50 has a first position and a second position relative to the housing 40. The protrusion degree of the movable body 50 relative to the back face 402 in the first position is lower than the protrusion degree of the movable body 50 relative to the back face 402 in the second position. The elastic member 60 is connected to the movable body 50. The elastic member 60 is configured to generate a restoring elastic force, which is capable of moving the movable body 50 from the first position to the second position. The magnetic sensitive member 70 is connected to the housing 40. The magnetic sensitive member 70 is disposed on the side of the back face 402 close to the main face 401. The magnetic sensitive member 70 has a first electrical state and a second electrical state. In the first position, the distance between the movable body 50 and the magnetic sensitive member 70 is less than a predetermined trigger distance, and the magnetic sensitive member 70 is in the first electrical state. In the second position, the distance between the movable body 50 and the magnetic sensitive member 70 is not less than the predetermined trigger distance, and the magnetic sensitive member 70 is in the second electrical state.

[0042] The wireless pair device 100 of the present application, before the housing 40 is installed on the fixed structure, the movable body 50 is in the second position under the action of the elastic member 60, the distance between the movable body 50 and the magnetic sensitive member 70 is not less than the predetermined trigger distance, no magnetic coupling is formed between the movable body 50 and the magnetic sensitive member 70, and the magnetic sensitive member 70 is in the second electrical state. When the housing 40 is installed on the fixed structure, the back surface 402 of the housing 40 is opposite to the surface of the fixed structure. When the back surface 402 of the housing 40 is attached to the surface of the fixed structure, the surface of the fixed structure pushes the movable body 50, the movable body 50 moves to the first position, the distance between the movable body 50 and the magnetic sensitive member 70 is less than the predetermined trigger distance, the magnetic coupling is formed between the movable body 50 and the magnetic sensitive member 70, and the magnetic sensitive member 70 is in the first electrical state. In the case that the wireless pair device 100 is illegally disassembled, when the back surface 402 of the housing 40 is away from the surface of the fixed structure, the movable body 50 loses the support of the fixed structure and moves to the second position under the action of the restoring force, and the magnetic sensitive member 70 switches from the first electrical state to the second electrical state. Through the state switching, the magnetic sensitive member 70 can trigger the control circuit 80 to enter the alarm state. Therefore, even if the detection light is not blocked before and after the illegal disassembly, as long as the housing 40 is separated from the surface of the fixed structure, the control circuit 80 can enter the alarm state, avoiding that the illegal disassembly leads to the failure of the protection function of the wireless pair device 100.

[0043] In some embodiments, in combination with Figure 5 and Figure 6 As shown in the figures, the housing 40 includes a base 41 having a wall portion 411. The wall portion 411 has opposite support ends 412 and an open end 413. The movable body 50 has a first end 501 and a second end 502. The first end 501 of the movable body 50 is slidingly accommodated in the wall portion 411, and the second end 502 is away from the support end 412 of the wall portion 411 relative to the first end 501. The movable body 50 moves through the open end 413. The elastic member 60 is abutted between the support end 412 of the wall portion 411 and the first end 501 of the movable body 50. Understandably, during the installation of the wireless pair device 100, the second end 502 of the movable body 50 is used to abut the fixed structure. Relative to the open end 413, the support end 412 is close to the magnetic sensitive member 70. When the second end 502 of the movable body 50 is pushed by the fixed structure, the first end 501 of the movable body 50 moves close to the support end 412 of the wall portion 411, compressing the elastic member 60, and at the same time, the first end 501 of the movable body 50 moves close to the magnetic sensitive member 70, the distance between the movable body 50 and the magnetic sensitive member 70 is shortened, so that the magnetic sensitive member 70 can switch from the second electrical state to the first electrical state.

[0044] Exemplarily, the elastic member 60 is a compression spring. Exemplarily, the first end 501 of the movable body 50 has magnetism.

[0045] Exemplarily, the magnetic sensitive member 70 is arranged on the side of the supporting end 412 which is away from the open end 413.

[0046] Optionally, the wall shell part 411 is integrally connected with other parts of the base 41, so as to improve the sealing of the inner space of the shell 40 and improve the waterproof effect.

[0047] In some embodiments, in combination with Figure 6 and Figure 7 As shown, the outer diameter of the first end 501 of the movable body 50 is greater than the outer diameter of the second end 502, so that a larger contact area is formed between the first end 501 of the movable body 50 and the elastic member 60, which is conducive to improving the assembly stability of the elastic member 60.

[0048] In some embodiments, in combination with Figure 6 As shown, the outer diameter of the first end 501 of the movable body 50 corresponds to the inner diameter of the wall shell part 411. Optionally, the outer diameter of the first end 501 of the movable body 50 is slightly smaller than the inner diameter of the wall shell part 411. Optionally, the outer diameter of the first end 501 of the movable body 50 is equal to the inner diameter of the wall shell part 411, so that the wall shell part 411 can define the sliding direction of the movable body 50 relative to the shell 40.

[0049] In some embodiments, in combination with Figure 4 and Figure 6 As shown, the shell 40 further comprises a cover plate 42 covering the open end 413 of the wall shell part 411. The movable body 50 is movably inserted into the cover plate 42. Understandably, after the cover plate 42 is fixed relative to the wall shell part 411, the cover plate 42 can cooperate with the wall shell part 411 to define the movement range of the first end 501 of the movable body 50. Understandably, the cover plate 42 is provided with a through hole 422. The outer diameter of the first end 501 of the movable body 50 is greater than the inner diameter of the through hole 422. The outer diameter of the second end 502 of the movable body 50 is not greater than the inner diameter of the through hole 422.

[0050] Exemplarily, in combination with Figure 6 As shown, the base 41 is provided with a plurality of screw holes 414 distributed along the outer periphery of the wall shell part 411. The cover plate 42 is provided with a plurality of first mounting holes 421. The positions of the first mounting holes 421 correspond to the positions of the screw holes 414. Understandably, by passing fasteners through the corresponding screw holes 414 and first mounting holes 421, the cover plate 42 and the wall shell part 411 can be kept relatively fixed.

[0051] In some embodiments, in combination with Figure 6 and Figure 7As shown, the movable body 50 includes a top rod 51 and a magnet 52. The magnet 52 is inserted into the top rod 51, so that the movable body 50 is partially magnetic, and the top rod 51 protects the magnet 52. The top rod 51 is slidingly connected to the housing 40.

[0052] Optionally, the magnet 52 is exposed from the top rod 51 near one end of the magnetically sensitive member 70, so as to improve the magnetic coupling between the magnet 52 and the magnetically sensitive member 70. The top rod 51 covers the outer periphery of the magnet 52, and the top rod 51 also covers the end of the magnet 52 away from the magnetically sensitive member 70, so as to avoid direct abutment between the magnet 52 and the fixed structure. Exemplarily, the magnet 52 is made of ferromagnetic material. Understandably, the orientation of the end of the magnet 52 away from the magnetically sensitive member 70 is substantially the same as the orientation of the back surface 402.

[0053] In another embodiment, the movable body 50 is made of ferromagnetic material as a whole.

[0054] In some embodiments, in combination with Figure 6 and Figure 7 As shown, the magnet 52 is in a columnar shape, and the length direction of the magnet 52 corresponds to the sliding direction of the top rod 51 relative to the housing 40, so as to facilitate improving the magnetic strength of the end of the movable body 50, and improving the magnetic field variation range near the magnetically sensitive member 70, so that the magnetically sensitive member 70 can more accurately sense the position change of the movable body 50.

[0055] In some embodiments, in combination with Figure 6 and Figure 7 As shown, the movable body 50 is provided with a limiting groove 503 at the first end 501. The opening of the limiting groove 503 faces the supporting end 412 of the wall shell part 411. One end of the elastic member 60 is accommodated in the limiting groove 503, so as to limit the relative position between the one end of the elastic member 60 and the first end 501 of the movable body 50, avoid the elastic member 60 from being bent or inclined, and ensure that the compression direction of the elastic member 60 is parallel to the linear sliding direction of the movable body 50.

[0056] Optionally, the limiting groove 503 is arranged at one end of the top rod 51, and the limiting groove 503 is distributed around the outer periphery of one end of the magnet 52.

[0057] In some embodiments, in combination with Figures 2 to 4As shown, the housing 40 comprises a base 41 and a cover 43. The cover 43 has an assembled state and a disassembled state relative to the base 41. The movable body 50 is movably connected to the base 41. The magnetic sensitive element 70 is connected to the cover 43. In the disassembled state, the distance between the movable body 50 and the magnetic sensitive element 70 is not less than a predetermined triggering distance, and the magnetic sensitive element 70 is in a second electrical state. Understandably, since the movable body 50 is connected to the base 41 and the magnetic sensitive element 70 is connected to the cover 43, when the cover 43 is illegally disassembled from the base 41, the distance between the movable body 50 and the magnetic sensitive element 70 increases, so that the magnetic sensitive element 70 can be switched from the first electrical state to the second electrical state, thereby triggering the control circuit 80 to enter the alarm state.

[0058] Exemplarily, in combination with Figure 3 As shown, the cover 43 is mounted with the transmitting module 20 and the receiving module 30. The control circuit 80 is connected to the cover 43.

[0059] Exemplarily, the housing 40 further comprises a shell 44, and the shell 44 and the cover 43 enclose a space for accommodating the transmitting module 20 or the receiving module 30.

[0060] Exemplarily, the surface of the base 41 opposite to the cover 43 serves as a back surface 402 of the housing 40. Exemplarily, in the assembled state, the cover 43 is arranged opposite to the base 41 along a predetermined direction, and along a projection direction parallel to the predetermined direction, the position of the magnetic sensitive element 70 on the projection plane corresponds to the position of the magnet 52 on the projection plane, so that in the assembled state, the distance between the magnetic sensitive element 70 and the magnet 52 is short, and the magnetic sensitive element 70 and the magnet 52 can be in the first electrical state.

[0061] In some embodiments, in combination with Figure 2 and Figure 3 As shown, the base 41 is provided with a plurality of second mounting holes 415. In the assembled state, the cover 43 covers the second mounting holes 415. Understandably, after passing through the second mounting holes 415, the fasteners are connected to the fixing structure, so that the base 41 can be fixed to the fixing structure. After the base 41 is fixed to the fixing structure, the cover 43 covers the second mounting holes 415, so that the fasteners can be prevented from being disassembled.

[0062] Exemplarily, the magnetic sensitive element 70 is electrically connected between two terminals of the control circuit 80, so as to adjust the electrical state between the two terminals of the control circuit 80. The control circuit 80 determines whether to enter the alarm state according to the electrical state between the two terminals. Exemplarily, the magnetic sensitive element 70 can make the two terminals of the control circuit 80 in a short-circuit state or an open-circuit state.

[0063] Optionally, the magnetic sensitive member 70 is in a short-circuit state between the two terminals of the control circuit 80 in the first electrical state, and is in an open-circuit state between the two terminals of the control circuit 80 in the second electrical state.

[0064] Optionally, the magnetic sensitive member 70 is in an open-circuit state between the two terminals of the control circuit 80 in the first electrical state, and is in a short-circuit state between the two terminals of the control circuit 80 in the second electrical state.

[0065] Optionally, the magnetic sensitive member 70 is a dry reed. Optionally, the magnetic sensitive member 70 is a Hall sensor element.

[0066] In some embodiments, the magnetic sensitive member 70 is configured to be in the first electrical state when the magnetic sensitive member 70 is in a first magnetic state, and is configured to be in the second electrical state when the magnetic sensitive member 70 is in a second magnetic state. Figure 5 As shown, the wireless transceiver 100 further comprises an energy storage member 90 electrically connected to the control circuit 80. It is appreciated that the energy storage member 90 is capable of providing power to the control circuit 80. Exemplarily, the energy storage member 90 is connected to the housing 43.
