Description

Technical Field

[0001] The utility model relates to the technical field of induction switches, and in particular to a microwave radar induction switch. Background Art

[0002] Microwave radar induction switches detect the movement of objects through a non-contact method. When a person or object moves within the microwave radar's sensing range, the sensor automatically activates and controls the switch's on and off state. Microwave radar induction switches offer excellent anti-interference capabilities and are unaffected by environmental factors such as temperature, humidity, light, airflow, and dust. They can be easily installed in various non-metallic enclosures without affecting detection capabilities.

[0003] Existing devices have some disadvantages during use. For example, microwave radar sensor switches are usually fixed with screws or other fasteners. These fasteners may be numerous and complexly distributed, resulting in a lot of time and effort required for disassembly. In addition, some fasteners may be hidden in difficult-to-reach locations, increasing the difficulty of disassembly. The casing of some microwave radar sensor switches is relatively compact and does not reserve sufficient disassembly space. This may require destroying the casing or using special tools during disassembly, thereby increasing the complexity and cost of disassembly. Utility Model Content

[0004] The purpose of the utility model is to provide a microwave radar sensor switch to solve the problem that the shell design of some microwave radar sensor switches is relatively compact and there is not enough space reserved for disassembly, which may require destroying the shell or using special tools during the disassembly process, thereby increasing the complexity and cost of disassembly.

DETAILED DESCRIPTION

[0018] 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.

[0019] Example

[0020] like Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a microwave radar induction switch, comprising a bottom cover 1 and an upper cover 11, a snap-on assembly 2 is provided between the upper cover 11 and the bottom cover 1, a circuit board 12 is placed on the inner bottom wall of the bottom cover 1, a wiring terminal 13 is fixedly mounted on one side of the upper end face of the circuit board 12, a microwave sensor 14 is fixedly mounted at the center of the upper end face of the circuit board 12, a second indicator light 15 and a first indicator light 16 are also fixedly mounted on the upper end face of the circuit board 12, the power output end of the wiring terminal 13 is electrically connected to the power output end of the circuit board 12, and the power output end of the circuit board 12 is electrically connected to the power input end of the microwave sensor 14. In specific use, when the user connects the switch to the power supply, the power supply 13 is electrically connected to the power supply 12. After the system is powered on, the microwave sensor 14 starts working, emitting microwave signals and waiting for reflected signals. When a person or object enters the sensing range, the microwave signal is reflected back and received by the sensor, thereby triggering the switch. At this time, the relevant circuits on the circuit board 12 will be activated, causing the output end of the switch to generate an electrical signal or control signal to control the on or off of the connected load equipment (such as lamps, electrical appliances, etc.). At the same time, the second indicator light 15 and the first indicator light 16 will also light up, providing the user with an intuitive indication of the working status of the switch. The design of the snap-on assembly 2 makes the installation and removal of the bottom cover 1 and the upper cover 11 relatively simple and quick, making it convenient for users to perform maintenance and replacement.

[0021] As an implementation method in this embodiment, Figure 3 As shown, the snap assembly 2 includes a snap piece 21, which is symmetrically arranged on the two opposite side walls of the bottom of the upper cover 11. The snap piece 21 is provided with a docking port 22. The two opposite outer walls of the bottom cover 1 are fixedly connected with a snap protrusion 23 adapted to the docking port 22. During use, the user needs to align the upper cover 11 with the bottom cover 1 and ensure that the docking port 22 on the snap piece 21 corresponds to the snap protrusion 23 on the bottom cover 1. Then, press the upper cover 11 downward with appropriate force so that the snap protrusion 23 can be smoothly inserted into the docking port 22. During this process, a slight "click" sound may be heard, indicating that the snap assembly 2 has successfully connected the upper cover 11 and the bottom cover 1 together.

[0022] As an implementation method in this embodiment, Figure 4As shown, a plurality of interference rods 17 for contacting the circuit board 12 are fixedly connected to the inner top wall of the upper cover 11. The number, position and length of the interference rods 17 are carefully calculated (it should be noted that the lengths of the interference rods 17 are not the same, when the lower end surfaces of the plurality of interference rods 17 are on the same horizontal plane), so that they can be in close contact with the corresponding positions on the circuit board 12 during installation. When the upper cover 11 and the bottom cover 1 are connected together through the clamping assembly 2, the interference rods 17 will gently contact the surface of the circuit board 12, thereby fixing it in the correct position inside the bottom cover 1.

[0023] As an implementation method in this embodiment, Figure 3 As shown, a plurality of rubber limit blocks 101 are fixedly connected to the inner wall of the bottom cover 1, and the side walls of the plurality of rubber limit blocks 101 are in contact with the outer wall of the circuit board 12. The design of the rubber limit blocks 101 not only ensures the accurate positioning of the circuit board 12 during the installation process, but also provides necessary buffer protection to prevent damage caused by vibration or impact.

[0024] As an implementation method in this embodiment, Figure 2 As shown, a plurality of positioning holes 121 are provided in an array on the upper end surface of the circuit board 12 and on a side away from the wiring terminals 13. A plurality of mounting holes 111 corresponding to the positioning holes 121 are provided in an array on one side of the upper cover 11. Knobs 18 are inserted into both the positioning holes 121 and the mounting holes 111. The bottom end of the knob 18 contacts the bottom wall of the bottom cover 1. The pressure generated by the knob 18 makes the contact between the circuit board 12 and the bottom cover 1 tighter, thereby improving the heat dissipation performance and electromagnetic shielding effect of the switch.

[0025] As an implementation method in this embodiment, Figure 4 As shown, a plurality of through holes 112 are provided on both sides of the upper cover 11, and the second indicator light 15 and the first indicator light 16 pass through the corresponding through holes 112 respectively. The through holes 112 not only provide necessary channels for the second indicator light 15 and the first indicator light 16, so that they can be smoothly installed inside the switch and ensure their normal operation, but also keep the appearance of the switch neat and beautiful.

[0026] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
