Description
Technical field
The utility model relates to inertial navigation, in particular to a kind of optical fiber inertial navigation structure.
Background technique
In recent years, domestic market optical fiber inertial navigation ruler rapid to miniaturization, low cost, middle precision IMU demand growth, previous
Very little big, weight weight, at high cost, competitiveness is weak, and quality, cost are that emphasis considers in the design of Miniature optical fiber inertial navigation structure
Factor.
Summary of the invention
The technical issues of the utility model solves: propose that a kind of satisfaction can reasonable installation closed-loop fiber optic gyroscope and acceleration
Meter, system reaches middle precision, and the optical fiber inertial navigation structure that size is smaller, internal arrangement is compact.
The technical solution of the utility model includes: a kind of optical fiber inertial navigation structure, it is characterized in that: integrated gyro installation seat and plus meter
Mounting base, gyro installation stage body and plus meter installation stage body in laterally disposed.
Preferably, the gyro installation stage body bottom extends around, forms installation stage body 1, installs and be arranged on stage body 1
There is the fixed structure of external connection.Installation stage body is set to be connected with mounting surface.
Preferably, the inertial navigation structure further includes outer cover 2 under cabinet, and outer cover 2 is mounted on erecting bed under the cabinet
Outside body 1, bottom and installation stage body 1 are fixed.Outer cover 2 under cabinet is set to be connected with installation stage body.
Preferably, the inertial navigation structure further includes cabinet upper casing 3, and the cabinet upper casing [3] is mounted on cabinet
Outer cover 2 is fixed under lower 2 top of outer cover, bottom and cabinet.It is integrated the installation of inertial navigation structure.
Preferably, the wall thickness of outer cover 2 is 2-3mm under the cabinet.Can be with bearer circuit plate, and make inner sealing.
Preferably, the wall thickness of the cabinet upper casing 3 is 1-2mm.It maximizes and mitigates whole system weight.
Preferably, system circuit board is installed on 2 outer wall of outer cover under cabinet.
The utility model has the beneficial effects that the utility model designs a kind of optical fiber inertial navigation structure, guarantee three gyros, three
It is orthogonal (X, Y, Z) that accelerometer installation is able to satisfy three axis；Previous optical fiber inertial navigation structure is compared, is by accelerometer and gyro
It installs on two different stage bodies respectively, total size is larger, and horizontal space is utilized in the design, makes plus count erecting bed
Body and gyro installation stage body are fixed together, and in laterally one arrangement, while under installation stage body and cabinet after outer cover installation
Guarantee airtight；The installation system circuit board above outer cover under cabinet maximizes and improves space utilization rate, reduces product size；By
On system parts are installed under cabinet, cabinet upper casing is not carried, and can guarantee to reduce when meeting rigidity requirement
Wall thickness, and then mitigate product weight, it provides the foundation for the Miniaturization Design of system；Install stage body be less than 110mm ×
The rectangle of 100mm, it is similar to U.S.'s Nuo Ge company LN-200 series of products to design its four installation hole locations, can even replace to mark
Change LN-200；Another aspect accelerometer and gyro sub-moduleization are installed, and are the debugging of product later period, assembly, repair or upgrade etc.
Convenience is provided.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is that the utility model installs 1 structural schematic diagram of stage body.
Specific embodiment
The utility model is described in further detail now in conjunction with attached drawing, embodiment:
Referring to Fig. 1, which includes 3 components, installs stage body 1, outer cover 2 and cabinet upper casing 3 under cabinet.Erecting bed
Body is by gyro installation platform and meter installation stage body body bottom is added to extend obtain around, and there are four the fixed of external connection to pacify for upper setting
Hole location is filled, installation interface is similar to LN-200 series of products.
Referring to fig. 2, gyro installation stage body is the cube structure for having cavity, and three optical fibre gyros are mounted on cavity bottom
On the outside of portion and cavity on normal surface, the relevant circuit board of gyro is mounted in the middle part of cavity, another side on the outside of top and cavity, platform
The remaining unique side of body is accelerometer stage body, it is compact-sized, arrangement space utilization rate it is high, with gyro installation stage body in cross
To integrated arrangement, it is orthogonal that total guarantees that three gyros, the installation of three accelerometers are able to satisfy three axis, due to system zero
Component is installed under cabinet on outer cover 2, under finally from top to bottom covering cabinet outer cover 3, is connected with outer cover under cabinet by screw
It connects.Since outer cover does not carry under cabinet, can guarantee to reduce wall thickness when meeting rigidity requirement, wall thickness can be reduced to 1-2mm,
Mitigate product weight to a certain extent.The structure largest enveloping surface size (containing mounting flange) is the rectangular of 108mm × 97mm
Shape, high 130mm, product quality are less than 2kg.
