Abstract
The utility model discloses a machine oil MEMS pressure sensor based on an adapter piece fixing structure. The machine oil MEMS pressure sensor based on the adapter piece fixing structure comprises a shell, a connecting member, a first adapter piece, a pressure ring, a second adapter piece and a packaging member. The connecting member is located in the shell, the first adapter piece is located on the outer end face of the connecting member, and the pressure ring is pressed on the outside of the connecting member; the pressure ring and the shell are in threaded connection, the second adapter piece is arranged in the pressure ring, and the packaging member is in threaded connection with the pressure ring are, and is pressed against and connected with the outer end face of the second adapter piece. According to the utility model, the packaging member is arranged outside the second adapter piece, so that the second adapter piece is fixed and packaged.
Description
Technical field
The utility model relates to a kind of car force sensor, and particularly a kind of volume with MEMS technology development is little, lightweight, response is fast, highly sensitive, be easy to batch production, engine oil pressure pickup cheaply.
Background technology
Automobile sensor as the information source of Auto Electronic Controlled System, is the critical component of Auto Electronic Controlled System, is also one of core content of technical field of automotive electronics research.Automobile sensor carries out in real time, measures accurately and control various information such as temperature, pressure, position, rotating speed, acceleration and vibrations.The key of weighing modern sedan limousine control system level just is quantity and the level of its sensor.
Microelectromechanical systems (MEMS) technology of coming from the SIC (semiconductor integrated circuit) technical development is day by day ripe, utilize this technology can make various microsensors, volume and the energy consumption of these sensors are little, can realize many brand-new functions, be convenient in enormous quantities and made with high precision, cost per unit is low, easily consists of extensive and multifunctional array, is highly suitable on automobile and uses.
Because the MEMS sensor has irreplaceable advantage, traditional pressure sensor for automobile will progressively be replaced by it.MEMS Lubricant of Automobile Engine and abs pressure sensor are by the domestic cumulative year after year of current needs, maturation along with domestic MEMS car force sensor technology, having the MEMS pressure transducer of the characteristics such as microminiaturization, low-power consumption, high sensitivity, high reliability, will be the focus of Global Auto transducer market product demand.
At present, can provide automobile MEMS pressure transducer mainly take offshore company as main, the companies such as U.S. Kai Leer, extraordinary measurement, SSI, Fei Erke, Texas Instrument, German Bosch, Japan electric coating are arranged, annual production is more than 2,000,000.The automobile MEMS pressure transducer of the international renowned company Development and Production such as external Motorola, Infineon, GE adopts folded silicon technology mostly, the technologies such as bulk silicon technological, have highly sensitive, the precision high, range 50 to 1400KPa, precision 0.03%FS, but also have in some aspects complex manufacturing technology, high-precision capacitance pressure transducer, easily is subjected to environmental interference, and the problem such as easily is subject to disturbing between the pollution of environment and many signals.
As shown in Figure 1, outside need and the switching piece of the interconnect of the MEMS pressure transducer of prior art are fixed, the switching piece outside of using at present all is not fixed, so the stability of sensor when work is just relatively poor, inner body easily becomes flexible or comes off, and causes sensor normally to use.
