The base is equipped with a circuit board, the circuit board is equipped with a supporting frame, the supporting frame is equipped with a microwave device plate, a microwave aerial is arranged in the middle of the microwave device plate, and a lead-out conducting wire of the microwave device plate is connected with the circuit board on the base. Electric components combining an electric circuit are mounted on a printing circuit board, the microwave device plate is placed on an electric circuit board, and the microwave device plate and the electric circuit board are separated by the supporting frame, thereby preventing operation of the microwave device plate from being disturbed by operation of various components on the electric circuit board. Particularly, frequency mixing and resonant vibration of the microwave plate are not affected by electromagnetic field distributions of various capacitors and inductors on the electric circuit board, and radiating of the circuit board does not affect parameters of the capacitors and the inductors on the microwave device plate, thereby enabling signal transmitting and receiving to be stable and keeping operation stability. The microwave induction box structure can reduce design area and can be designed to be small and exquisite, thereby increasing beauty level of the appearance.
Description
Technical field
The utility model relates to a kind of structure of microwave induced device, particularly a kind of microwave induced box body.
Background technology
The Doppler effect of microwave makes microwave induced device have broad application prospect aspect the detection mobile object, it is compared with infra-red detection, have that the nonmetallic materials of not being subjected to intercept, can surmount stopping such as plastics, glass and timber, detect the mobile status of unknown object in the particular range, and be not subjected to the interference of surrounding environment thermal source, and can round-the-clock work, mobile object is made reaction accurately.But the microwave induced device that uses still exists many big and small deficiencies to influence the development of microwave induced device at present, for example various microwave devices all comprise microwave component and microwave circuit two partly, this two part all is produced on the same printed circuit board, because the restriction of printed wire area, the electronic devices and components dense arrangement degree of microwave circuit more or less influences inductance in the microwave device, changes in capacitance, and problems such as the electromagnetism distribution of wiring board, heat radiation all influence the reliability of microwave emission and reception and result of detection.
Summary of the invention
The utility model influence integrity problem at present the existence when making detector with microwave device and microwave circuit, designs a kind of new box body structure, and the microwave induced box that a kind of microwave device and microwave circuit are independent of each other is with the reliability of raising microwave sensor.
Design proposal of the present utility model is: microwave induced box structure, comprise the lid and the base that fuse with box body, it is characterized in that establishing on the base wiring board, establish support frame on the wiring board, establish the microwave device plate on the support frame, establish a microwave antenna in the middle of the microwave device plate, the wiring board on the drawing lead and be located at base of microwave device plate is connected.
The basic ideas of above-mentioned design are divided into 2 to printed-wiring board (PWB) exactly, wherein one based on microwave device, another piece is to make signal processing circuit, all be installed on the printed-wiring board (PWB) electronic devices and components of forming electronic circuit, the microwave device plate is put and is placed on the electronic circuit board, the centre separates microwave device plate and electronic circuit board with support frame, the benefit of this design is conspicuous, at first be to make the work of microwave device plate not be subjected to the interference of various components and parts work on the electronic circuit board, just do not disturb mutually, the particularly mixing of microwave board, resonance is not subjected to many electric capacity on the circuit plate, the influence that the inductance electromagnetic field distributes, be that the wiring board heat radiation does not influence electric capacity on the microwave board again, inductance parameters, transmit and receive signal stabilization thereby make, the stability of maintenance work, be the design area that can reduce the microwave sensor box in addition, can design smaller and more exquisitely, improve aesthetic appearance.
