Description

Technical Field

[0001] The utility model relates to an inertial navigation technology, in particular to a quickly installed inertial navigation product structure. Background Art

[0002] Inertial navigation technology is used to determine the attitude, speed and position parameters of moving objects. This technology is widely used in aerospace, aviation, navigation and geodesy. At present, MEMS integrated navigation system has been widely recognized in the civil and military fields. In the civil field, automobiles with navigation and positioning functions, precision agricultural machinery and vehicles, unmanned aircraft used for pesticide spraying and forest fire prevention, etc. have been partially equipped with this type of integrated navigation system; in the military field, developed countries in Europe and the United States have successfully applied it to tactical guided weapons, micro-unmanned reconnaissance aircraft, satellite detection, spacecraft navigation and other fields.

[0003] Since MEMS sensors are implemented with micromechanical structures and are easily interfered with due to their own properties and design principles, long-term motion and hot and cold cycles in automobiles or other equipment will reduce the accuracy of inertial navigation products. The inertial navigation products need to be removed and recalibrated for temperature and linearity.

[0004] Normally, the structure of MEMS inertial navigation products needs to be fixed to the user's structure (mounting base) with three or four screws. When the inertial navigation product needs to be recalibrated, the three or four screws need to be removed with a screwdriver. When replacing the new inertial navigation product, the screws also need to be re-tightened, which is inconvenient for quick replacement. In special scenarios, it becomes a necessity to quickly replace problematic inertial navigation products. Utility Model Content

[0023] Embodiment 1:

[0024] like Figure 1 -3 shows a quick-install inertial navigation product structure, including a product housing 1 and a base 2, wherein a stud 3 is provided at the center of the base 2, and a mounting sleeve 7 is provided at the center of the product housing 1, wherein the inner wall of the mounting sleeve 7 is provided with an internal thread, and the stud 3 cooperates with the internal thread.

[0025] The quick-installation inertial navigation product structure of this embodiment is designed with a threaded mounting sleeve 7 and a base 2 with studs 3. The inertial navigation product can be directly screwed onto the base 2 with the mounting studs 3 by hand, realizing quick installation without screw fixation, saving manpower and time.

[0026] The base 2 is provided with a PCB board 4, the stud 3 passes through the PCB board 4, and the PCB board 4 is fixed to the base 2 by a fixing bolt 5; the product housing 1 is provided with a mounting sleeve 7, a wire outlet hole 6 is provided on one side of the outer periphery, and an interface is provided on the PCB board 4; an inertial navigation component is provided in the product housing 1, and a connecting wire is provided on the inertial navigation component, the connecting wire passes through the wire outlet hole 6 and a connector is provided at the end, and the connector cooperates with the interface.

[0027] The inertial navigation unit uses inertial elements (accelerometers and gyroscopes) to measure the acceleration and angular velocity of the vehicle itself, and obtains the speed and position through integration and calculation, so as to achieve the purpose of navigation and positioning of the vehicle. The devices that make up the inertial navigation unit are all installed in the vehicle. When working, they do not rely on external information, do not radiate energy to the outside world, and are not easily interfered with. They are an autonomous navigation system. The inertial navigation unit is usually composed of an inertial measurement device, a microprocessor, etc. The inertial measurement device includes an accelerometer and a gyroscope, also known as an inertial measurement unit. The three-degree-of-freedom gyroscope is used to measure the three rotational motions of the vehicle; the three accelerometers are used to measure the acceleration of the three translational motions of the vehicle. The microprocessor calculates the speed and position data of the vehicle based on the measured acceleration signal.

[0028] The installation sleeve 7 is provided with two positioning holes 8, and the positioning holes 8 are matched with positioning pins. The positioning pins pass through the positioning holes 8 and abut against the stud 3. The setting of the positioning pins and the positioning holes 8 can limit the stud 3 and the installation sleeve 7 to prevent the installation sleeve 7 and the stud 3 from loosening.

When assembling, you only need to align the installation sleeve 7 with the stud 3 and tighten it, then insert the positioning pin into the positioning hole 8, lock the stud 3 and the installation sleeve 7, and then insert the connector into the interface.
