Description

Technical Field

[0001] This utility model relates to the field of inertial sensor technology, and in particular to an inertial sensor limiting structure. Background Technology

[0002] An inertial sensor limiting structure is a mechanical constraint device designed to ensure the stable operation of an inertial sensor within its normal operating range. Its core function is to limit excessive displacement of the sensor's internal sensitive elements when subjected to excessive acceleration, impact, or vibration, preventing damage or performance degradation. This structure typically employs elastic supports, mechanical stops, or cushioning materials to limit the maximum displacement while maintaining sensor sensitivity. By rationally designing the limiting structure, the reliability and lifespan of the sensor can be improved, making it particularly suitable for applications sensitive to vibration and shock, such as automotive safety systems and aerospace.

[0003] However, existing limiting mechanisms require the sensor to be pre-installed on a mounting bracket or plate, and limiting structures to be set around the bracket or plate. This results in problems such as inconvenient installation, large space occupation, difficulty in accurately adjusting the sensor's installation level, affecting measurement accuracy, and easily leading to inaccurate measurement data. These drawbacks exist in the usage process.

[0004] In view of the above, this utility model is hereby proposed. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] like Figures 1-5 As shown, this embodiment provides an inertial sensor limiting structure, including a positioning connecting frame 1 and a sensor body 2. An upper limit mounting plate 3 and a lower limit mounting plate 4 are fixedly installed on the positioning connecting frame 1. Press-fit limiting components 5 are installed on both the upper limit mounting plate 3 and the lower limit mounting plate 4. A mounting base plate 6 is provided between the upper and lower press-fit limiting components 5. The mounting base plate 6 is connected to the upper limit mounting plate 3 and the lower limit mounting plate 4 through a telescopic hinge 7. The mounting base plate 6 is slidably connected to the press-fit limiting components 5, and the press-fit limiting components 5 are distributed at the four corners of the mounting base plate 6. The sensor body 2 is fixed on the mounting base plate 6, and a level 8 is fixedly installed on one end of the mounting base plate 6. In use, the positioning connecting frame 1 is first fixed to the aircraft or other equipment. The positioning connecting frame 1 can reduce the volume of the limiting structure and reduce the installation area, making the installation of the limiting structure in the aircraft more convenient. Furthermore, by observing the level 8 on the mounting base plate 6, the press-fit limiting components 5 can be controlled to adjust the mounting base plate 6 to a horizontal state. When in use, the sensor body 2 is fixed on the mounting base plate 6. The mounting base plate 6 and the sensor body 2 are limited by the pressing and limiting components 5 and the telescopic hinge 7 on the upper limit mounting plate 3 and the lower limit mounting plate 4 to ensure their stability. Then it can be put into use. When the aircraft stops suddenly, the mounting base plate 6 drives the sensor body 2 to move due to inertia and is limited by the pressing and limiting components 5 and the telescopic hinge 7.

[0023] As a technical optimization solution of this utility model, specifically as follows: Figure 3As shown, the telescopic hinge 7 includes a telescopic connecting rod 701. The telescopic connecting rod 701 is rotatably mounted on the upper limit mounting plate 3 and the lower limit mounting plate 4 via a first hinge seat 702. The telescopic end of the telescopic connecting rod 701 is rotatably connected to the mounting base plate 6 via a second hinge seat 703. Both the first hinge seat 702 and the second hinge seat 703 are ball joint supports. During use, when the mounting base plate 6 tends to displace due to inertia, the telescopic connecting rod 701 flexibly rotates on the upper limit mounting plate 3 and the lower limit mounting plate 4 via the first hinge seat 702 to adjust the angle. At the same time, its telescopic end rotates relative to the mounting base plate 6 via the second hinge seat 703, and the telescopic connecting rod 701 extends and retracts accordingly, thereby dynamically adapting to the movement of the mounting base plate 6 and achieving effective positioning.

[0024] As a technical optimization solution of this utility model, specifically as follows: Figure 4 As shown, the crimping limiting assembly 5 includes a vertical threaded rod 501, a threaded slider 502 sleeved on the vertical threaded rod 501, a crimping post 503 fixedly installed on the threaded slider 502, a limiting ball 504 installed at one end of the crimping post 503, the limiting ball 504 being rotatably connected to the crimping post 503, the limiting balls 504 located at the four corners of the mounting base 6 respectively fitting into the circular limiting grooves opened at the four corners of the mounting base 6, the upper limiting mounting plate 3 and the lower limiting mounting plate 4 are both fixedly installed with limiting slide rods 505, the threaded slider 502 is slidably sleeved on the limiting slide rods 505, and a screwing head 506 is fixedly installed at one end of the vertical threaded rod 501. In use, by screwing the screwing head 506, the vertical threaded rod 501 is rotated, and the threaded slider 502 moves up and down along the vertical threaded rod 501 under the limitation of the limiting slide rod 505, thereby driving the crimping post 503 and the limiting ball 504 to rise and fall. Adjust the four corner limiting balls 504 so that they respectively mate with the circular limiting grooves at the four corners of the mounting base 6, thereby pressing and limiting the mounting base 6 to ensure the stability of the sensor body 2 during aircraft operation. Furthermore, combined with the telescopic hinge 7 and the level 8, the mounting base 6 can be adjusted to maintain a horizontal position, ensuring the accuracy of the sensor body 2 during use.

Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
