Description

Technical Field

[0001] The utility model relates to the technical field of inertial gyro positioning, and particularly relates to a digital mapping and positioning device for an inertial gyroscope. Background Art

[0002] An inertial gyroscope is a device that can sense and measure the rotation and direction change of an object, and is used in navigation and positioning systems. The digital mapping and positioning device utilizes the characteristics of the inertial gyroscope to determine the position, attitude and movement path of an object by recording the rotation and movement of the object. It can perform positioning and mapping without external reference points or signals, so it has important application value in some occasions that require complex environments or without GPS signals. The working principle of the device is to sense the rotation and movement of the object through inertial sensors, and then use internal algorithms and processors to process and analyze these data to finally determine the position and attitude of the object. The digital mapping and positioning device can be widely applied to fields such as aerospace, geographic information systems, unmanned aerial vehicles, and robots.

[0003] The positioning and mapping requirements involve various scenarios with different heights and angles. In some cases, mapping needs to be carried out at a lower height, while in other cases, positioning needs to be carried out at a higher height, and in some application scenarios, such as unmanned aerial vehicle aerial photography and mobile robot navigation, it is necessary to maintain the stability and attitude accuracy of the device.

[0004] Based on this, a digital mapping and positioning device for an inertial gyroscope is now proposed. Summary of the Utility Model

[0005] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0006] A digital mapping and positioning device for an inertial gyroscope, including a base, a driving mechanism is fixedly installed on the top of the base, the driving mechanism is drivingly connected to a lifting mechanism, a pan-tilt mechanism is installed on the top of the lifting mechanism, a gyroscope is installed on the top of the pan-tilt mechanism, the driving mechanism includes a motor; the lifting mechanism includes a base rod; the pan-tilt mechanism includes a pitch axis.

[0007] A further improvement of the technical solution of the utility model lies in that: fixing blocks are fixedly installed on both sides of the motor, the motor is drivingly installed with a lead screw, and one end of the lead screw is rotatably inserted into a base block.

[0008] A further improvement of the technical solution of the utility model lies in that: the driving mechanism is threadedly inserted into the lifting mechanism through the lead screw.

[0009] A further improvement of the technical solution of the present utility model lies in that: a slide rail is slidably inserted into the base rod, a cross frame is fixedly installed at the top of the base rod, and a platform is slidably installed at the top of the cross frame.

[0010] A further improvement of the technical solution of the present utility model lies in that: the top of the platform is used for placing a pan-tilt mechanism.

[0011] A further improvement of the technical solution of the present utility model lies in that: the lifting mechanism is fixedly installed on the driving mechanism through the slide rail, and the driving mechanism is threadedly inserted into the base rod.

[0012] A further improvement of the technical solution of the present utility model lies in that: a horizontal axis is rotatably installed at the top of the pitching axis, and an inclination axis is rotatably installed on one side of the horizontal axis.

[0013] A further improvement of the technical solution of the present utility model lies in that: the gyroscope is fixedly installed on the inclination axis.

[0014] Due to the adoption of the above technical solution, the technical progress achieved by the present utility model compared with the prior art is:

[0015] The present utility model provides an inertial gyroscope digital surveying and mapping positioning device. The driving mechanism is threadedly inserted into the lifting mechanism through a lead screw, and the motor can drive the lead screw to rotate at one end of the base block, so as to drive the bottom side of the lifting mechanism to move horizontally through the rotation of the lead screw. And two groups of driving mechanisms are arranged corresponding to the two sides of the bottom of the lifting mechanism, so that the bottom of the lifting mechanism can be driven by the driving mechanism to horizontally close and expand, for realizing the lifting of the lifting mechanism.

[0016] The present utility model provides an inertial gyroscope digital surveying and mapping positioning device. Two groups of driving mechanisms are arranged corresponding to the two sides of the bottom of the lifting mechanism, so that the bottom of the lifting mechanism can be driven by the driving mechanism to horizontally close and expand. When the bottom of the cross frame closes, the top of the cross frame will close synchronously. A platform is slidably installed at the top of the cross frame. When the cross frame closes, the overall height increases, so as to slide and push the platform to rise, and further make the pan-tilt mechanism and the gyroscope on the platform rise in height. On the contrary, when the driving mechanism drives the bottom of the lifting mechanism to horizontally expand, the pan-tilt mechanism and the gyroscope decrease in height. This inertial gyroscope digital surveying and mapping positioning device has a height-adjustable design and can adapt to the demand changes in different scenarios.

[0017] The present utility model provides an inertial gyroscope digital surveying and mapping positioning device. The gyroscope is fixedly installed on the inclination axis, and the gyroscope is movably installed on the surveying and mapping positioning device through three parts: the pitching axis, the horizontal axis, and the inclination axis, and can be calibrated in three axes, so that the gyroscope is always horizontal and stable, and will also remain stable when the device deflects and shakes, so that this inertial gyroscope digital surveying and mapping positioning device can help the gyroscope maintain stability during movement and improve the accuracy of surveying and mapping and positioning.

The lifting mechanism 3 is fixedly installed on the driving mechanism 2 through the slide rail 34, and the base rod 33 is threadedly inserted into the driving mechanism 2.

[0029] In this embodiment, two sets of driving mechanisms 2 are provided corresponding to both sides of the bottom of the lifting mechanism 3, so that the bottom of the lifting mechanism 3 can be driven by the driving mechanism 2 to horizontally close and expand. When the bottom of the cross frame 32 is closed, the top of the cross frame 32 will be closed synchronously. The top of the cross frame 32 is slidably installed with a platform 31. When the cross frame 32 is closed, the overall height increases, so as to slide and push the platform 31 to rise, and further make the pan-tilt mechanism 4 and the gyroscope 5 on the platform 31 rise in height. On the contrary, when the driving mechanism 2 drives the bottom of the lifting mechanism 3 to horizontally expand, the heights of the pan-tilt mechanism 4 and the gyroscope 5 decrease.

Two groups of driving mechanisms 2 are provided corresponding to both sides of the bottom of the lifting mechanism 3, so that the bottom of the lifting mechanism 3 can be driven by the driving mechanism 2 to close and expand horizontally. When the bottom of the cross frame 32 closes, the top of the cross frame 32 will close synchronously. A platform 31 is slidably installed on the top of the cross frame 32. When the cross frame 32 closes, the overall height increases, so as to slide and push the platform 31 to rise, and further make the height of the pan-tilt mechanism 4 and the gyroscope 5 on the platform 31 rise. On the contrary, when the driving mechanism 2 drives the bottom of the lifting mechanism 3 to expand horizontally, the height of the pan-tilt mechanism 4 and the gyroscope 5 drops.
