DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: an infrared microwave dual-mode sensor, comprising a shell body 1 and a wire connector 3, the inner top end of the shell body 1 is fixedly connected to the inner shell body 11, the inner top end of the shell body 1 is located below the inner shell body 11 and is fixedly connected to the shell base body 12, the inner side wall of the shell base body 12 is provided with a wire insertion end 18, the wire connector 3 is inserted into the inside of the wire insertion end 18, and the inner side wall of the shell base body 12 is provided at the end of the wire insertion end 18 with an anti-detachment structure to prevent the wire connector 3 from detaching.

[0021] By adopting the above solution, the combination of infrared and microwave dual modes can significantly improve the sensitivity and accuracy of the sensor. Infrared sensing can capture the heat changes of objects, while microwave sensing is more sensitive to the movement of objects. The combination of the two can cover a wider detection range and scenes, and improve the overall environmental perception ability. The anti-fall-off structure set on the inner wall of the shell body 12 can effectively prevent the wire connector 3 from accidentally falling off when used for a long time or subjected to external force, thereby ensuring the stability and safety of the electrical connection and reducing failures and safety hazards caused by poor contact or falling off.

[0022] like Figure 2 、 Figure 3 and Figure 4As shown, the anti-slip structure includes a fixing rod 22 symmetrically fixedly connected to the inner wall of the shell base body 12, and a limiting seat 21 is provided at the interval of the fixing rod 22 on the inner wall of the shell base body 12. The outer wall of the limiting seat 21 is symmetrically fixedly connected with a cross piece 25, and the end of the cross piece 25 is symmetrically fixedly connected with an elastic clamp 26 engaged with the fixing rod 22. The anti-slip structure also includes a pressing groove 23 provided on the top of the limiting seat 21 and in direct contact with the wire connector 3. A plurality of anti-slip pads 24 are fixedly connected to the inner wall of the pressing groove 23 in a circular array. The two ends of the pressing groove 23 have different sizes, and the size ratio of the two ends is one to one point three. The size of the end of the pressing groove 23 close to the wire connector 3 is larger than the other end.

[0023] By adopting the above scheme, a stable mechanical locking mechanism is formed through the clamping design of the fixing rod 22 and the elastic clamp 26, which can effectively prevent the wire connector 3 from falling off in an accidental situation, and also increase the reliability of the connection, ensuring the stable transmission of the electrical signal. The design of the cross piece 25 and the elastic clamp 26 fixed thereon enables the wire connector 3 to be disassembled by the anti-detachment structure through appropriate pressure when inserting and removing, and the elastic clamp 26 is deformed, thereby achieving fast and stable connection or separation. The design of the pressing groove 23 enables the wire connector 3 to fit tightly with it when inserted, and increases the friction through the anti-slip pad 24 to prevent poor contact due to vibration or external force. The design of the two ends of the pressing groove 23 with a size ratio of one to one point three helps to optimize the stress distribution when the wire connector 3 is inserted and reduce the risk of damage caused by stress concentration.

[0024] like Figure 2 As shown, the inner bottom end of the shell base body 12 is bolted to a fixing plate 14, the upper top of the fixing plate 14 is provided with a single-chip microcomputer 16, the upper top of the fixing plate 14 is located on one side of the single-chip microcomputer 16 and is fixedly connected to a microwave receiving module 17 for receiving external microwave signals, the upper top of the fixing plate 14 is located on one side of the microwave receiving module 17 and is fixedly connected to an infrared receiving module 15 for receiving external infrared signals, and the lower bottom end of the fixing plate 14 is fixedly connected to an elastic plate 2 that cooperates with the limit seat 21 to clamp the wire connector 3.

[0025] Using the above scheme, the microwave receiving module 17 and the infrared receiving module 15 are responsible for receiving external microwave signals and infrared signals respectively. They are precisely fixed on the fixing plate 14, which is conducive to reducing interference and attenuation during signal transmission and improving the accuracy and stability of signal reception. The elastic plate 2 and the limit seat 21 cooperate with each other to clamp and fix the wire connector 3, ensuring the stable connection of the wire connector 3. The elastic action of the elastic plate 2 also reduces the risk of loosening or falling off of the wire connector 3 due to vibration or external force.

[0026] like Figure 1 and Figure 2As shown, the outer wall of the shell body 12 is symmetrically provided with mounting grooves 13 , and the upper top of the fixing plate 14 is located on one side of the single chip computer 16 and is provided with an induction lamp, and the induction lamp passes through the upper top of the shell body 1 .

[0027] With the above solution, the design of the mounting groove 13 provides convenience for the installation of the sensor. Through the mounting groove 13, the sensor can be firmly fixed in the desired position. The setting of the sensor light enables the sensor to emit an obvious light signal when detecting a target object.

[0028] Working principle: During use, the end of the wire connector 3 is inserted into the interior of the wire insertion end 18, and then the limit seat 21 is installed from bottom to top, wherein a cross piece 25 is symmetrically fixedly connected to the outer wall of the limit seat 21, and the cross piece 25 is provided with elastic clamps 26 at both ends close to the fixing rod 22, which can be deformed after being subjected to force. At this time, the elastic clamps 26 can be clamped with the fixing rod 22, so that the outer wall of the wire connector 3 is located inside the pressing groove 23. Since the size of one end of the pressing groove 23 close to the end of the wire connector 3 is slightly larger than the other end, when the wire connector 3 wants to detach from the limit seat 21, under the influence of the pulling force, the clamping force of the limit seat 21 on the wire connector 3 will be further strengthened. The step is increased so that the limit seat 21 can control the end of the wire connector 3, and an anti-slip pad 24 is also provided inside the pressing groove 23, which can further increase the friction between the wire connector 3 and the limit seat 21. When it is necessary to release the connection between the wire connector 3 and the wire insertion end 18, the fixing rod 22 and the elastic clamp 26 are quickly disassembled so that the limit seat 21 no longer clamps the wire connector 3. At this time, the wire connector 3 can be easily removed from the inside of the wire insertion end 18. During use, the microwave receiving module 17 and the infrared receiving module 15 can respectively receive the signals emitted by the external infrared connector and the microwave connector, and transmit the signals to the single-chip microcomputer 16, which is controlled in a time-sharing manner by the single-chip microcomputer 16.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
