Technical field
The utility model relates to a kind of enclosure-type quartz flexible accelerometer, especially a kind of quartz flexible accelerometer that glueds joint the hermetically-sealed construction form.
Background technology
The principle of work of quartz flexible accelerometer is to utilize the force feedback principle to obtain one and the proportional electric current of input acceleration, obtains input acceleration information by the sampling to electric current.For satisfying the above-mentioned course of work, accelerometer inside is filled with the gas of certain pressure in order to the formation press-filming damping, thereby guarantees the stability of accelerometer control system.Because the application before the accelerometer is in atmospheric pressure environment, so does not have special hermetically-sealed construction in the prior art always.Continuous expansion along with the accelerometer application, the continuous variation of environmental stress, the continuous lifting of condition of work abominable, its sealing, environmental suitability have been had higher requirement, and the accelerometer of existing structure form can't satisfy the request for utilization that the user promotes day by day owing to lack hermetically-sealed construction.
The utility model content:
Technical problem to be solved in the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of enclosure-type quartz flexible accelerometer of simple in structure, good airproof performance is provided.
According to a kind of enclosure-type quartz flexible accelerometer that the utility model proposes, comprise accelerometer gauge outfit, hydrid integrated circuit, the upper surface of described accelerometer gauge outfit is provided with sealing ring, be provided with the hydrid integrated circuit that is connected with described accelerometer gauge outfit in the described sealing ring, be perfused with fluid sealant in the space that the upper surface of described sealing ring, described hydrid integrated circuit, described accelerometer gauge outfit constitutes.
The enclosure-type quartz flexible accelerometer that provides according to the utility model also has following additional technical feature:
Described sealing ring is connected with the upper surface of described accelerometer gauge outfit is bonding.
The upper surface employing thickness of described sealing ring and described accelerometer gauge outfit is that the fluid sealant of 0.02-0.4mm is bonding.
Described accelerometer gauge outfit is connected with described hydrid integrated circuit is bonding.
Described accelerometer gauge outfit and described hydrid integrated circuit employing thickness are that the structure glue of 0.05-0.4mm is bonding.
The fluid sealant of perfusion 3-8mm in the space that described sealing ring and hydrid integrated circuit upper surface constitute.
The enclosure-type quartz flexible accelerometer that provides according to the utility model compared with prior art has following advantage at least:
At first, because the design of enclosure-type quartz flexible accelerometer has special hermetically-sealed construction, therefore guarantee the sealing property of accelerometer under varying environment pressure, and then improved the environmental suitability of accelerometer under different operating modes, expanded the usable range of quartz flexible accelerometer; Secondly, the design of Sealing Structure of this kind enclosure-type quartz flexible accelerometer is simple, and process implementing is convenient, and cost is lower, and sealing property is stable, is suitable for producing in batches.
