The first mounting hole 31 and the second mounting hole 32 are aligned with each other. In this way, the device can be installed as a whole to a position where it is needed by using the first mounting hole 31 and the second mounting hole 32 that are aligned with each other and then using screws. When the screws pass through the first mounting hole 31 and the second mounting hole 32, the fixation between the bottom shell 1 and the top shell 2 is also achieved, killing two birds with one stone. The bottom shell 1 and the top shell 2 are provided with a shock-absorbing portion for positioning and shock-absorbing the posture sensor.

[0025] Reference Figure 1 , Figure 2 The plug-in portion includes a mounting strip 4 and a mounting slot 41. The mounting strip 4 is fixed on both sides of the bottom of the bottom shell 1.

The ends of the mounting strip 4 and the mounting slots 41 are provided with first fixing holes 42 aligned with each other, and the two groups of first fixing holes 42 are fixedly connected by screws. After the mounting strip 4 and the mounting slots 41 are plugged into each other, the two groups of first fixing holes 42 will be automatically aligned, and then the mounting strip 4 and the mounting slots 41 are fixed by horizontal screws; the upper part of the side wall of the bottom shell 1 is provided with a mounting protrusion 22, and the upper part of the side wall of the top shell 2 is provided with a mounting groove 5.

The two groups of second fixing holes 51 are fixedly connected by screws. When the mounting protrusion 22 is fully inserted into the mounting groove 5, the two groups of second fixing holes 51 will be automatically aligned. At this time, the mounting groove 5 and the mounting protrusion 22 are fixed from the top by screws. In summary, the locking fixation between the bottom shell 1 and the top shell 2 is realized from both vertical and horizontal directions, which effectively improves the fixing effect, ensures the installation stability between the bottom shell 1 and the top shell 2, and makes the installation more convenient. The fixing holes are automatically aligned after being plugged into each other, which improves the convenience of installation.

[0026] Reference Figure 1 , Figure 2 and Figure 4The shock absorbing part includes a horizontal shock absorbing rod 6, which is respectively fixed on the inner walls of the three sides of the top shell 2 and the side wall of the bottom shell 1, and the telescopic end of the horizontal shock absorbing rod 6 is fixedly connected with an extrusion plate 61, and the distance between the two opposite extrusion plates 61 is smaller than the distance between the opposite sides of the attitude sensor, and the side walls of each group of extrusion plates 61 are connected with two groups of symmetrically arranged horizontal shock absorbing rods 6, the top of the top shell 2 is fixedly connected with a vertical shock absorbing rod 62, and the telescopic end of the vertical shock absorbing rod 62 is fixedly connected with a pressing plate 63, and the distance from the pressing plate 63 to the bottom shell 1 is smaller than the height of the attitude sensor, and the two sides of the extrusion plate 61 and the pressing plate 63 are fixedly connected. The ends are both arc-shaped. In order to facilitate the insertion of the top shell 2, the extrusion plate 61 and the pressing plate 63 smoothly pass over the posture sensor, realizing the retraction of the horizontal shock-absorbing rod 6 and the vertical shock-absorbing rod 62. In this way, the shock-absorbing positioning is realized from all sides and the top of the posture sensor, which ensures the fixing effect while also producing a shock-absorbing effect. The horizontal shock-absorbing rod 6 and the vertical shock-absorbing rod 62 both adopt the form of a damping telescopic rod jacket shock-absorbing spring, which effectively absorbs the impact force generated during the impact of the posture sensor, improves the protection effect of the posture sensor, reduces the possibility of damage due to impact, and increases its service life.

[0027] Reference Figure 1 , Figure 2 Heat dissipation grooves 7 are provided on both sides of the top shell 2, and two groups of heat dissipation grooves 7 are symmetrically arranged along the central axis of the top shell 2, so that the opposite air flows can flow to each other, speeding up the gas flow rate in the top shell 2 after the bottom shell 1 is fixed, thereby improving the heat dissipation effect.

[0028] Reference Figure 1-Figure 4 , in the utility model, when in use, first place the attitude sensor at the center of the bottom shell 1, and make its side wall fit on the side wall of the extrusion plate 61, then pass the connecting wire of the attitude sensor through the connector hole 21, and then align the mounting slot 41 on the top shell 2 with the mounting strip 4 on the bottom shell 1 and insert it, so that the bottom shell 1 and the top shell 2 are plugged in, and in the final stage of the mutual plugging of the mounting slot 41 and the mounting strip 4, the mounting protrusion 22 will also be inserted into the mounting groove 5, when the plugging is completed, the horizontal two groups of first fixing holes 42 are aligned with each other, and the vertical two groups of second fixing holes 51 are aligned with each other, at this time, screws are respectively inserted into the first fixing holes 42 and the second fixing holes 51, so as to realize the locking fixation between the bottom shell 1 and the top shell 2 from both vertical and horizontal directions, effectively improving the fixing effect, ensuring the installation stability between the bottom shell 1 and the top shell 2, and making the installation more convenient, and automatically aligning the fixing holes after mutual plugging, which improves the convenience of installation;

[0029] In the process of pushing the top shell 2 to complete the insertion, the extrusion plate 61 on the inner wall of the top shell 2 and the pressing plate 63 on the top will pass over the posture sensor and make the horizontal shock absorbing rod 6 and the vertical shock absorbing rod 62 in a compressed state. Then, under the rebound effect of the horizontal shock absorbing rod 6 and the vertical shock absorbing rod 62, the posture sensor will be clamped and fixed. When the posture sensor needs to collide during use, the horizontal shock absorbing rod 6 and the vertical shock absorbing rod 62 will effectively absorb the impact force generated by the posture sensor during the collision, thereby improving the protection effect of the posture sensor, reducing the possibility of damage due to collision, and increasing its service life.
