Protection structure of tilt angle sensor and tilt angle sensor

The utility model relates to the technical field of tilt angle sensors, and provides a tilt angle sensor protection structure and a tilt angle sensor, which comprise a bottom plate and a fixed plate arranged at the top end of the bottom plate, the protection assembly comprises four groups of connecting frames arranged on the upper surface of the bottom plate, mounting holes formed in the connecting frames, first magnets connected to the interiors of the mounting holes, fixing sleeves connected to the outer surfaces of the first magnets in a sleeving manner, and silica gel pads arranged on the upper surfaces of the fixing sleeves; and two groups of mounting holes are formed in any group of connecting frames. According to the technical scheme, the problems that in the prior art, the shell is adopted and fixed to the outer portion of the tilt angle sensor part, the part is exposed in the air to be damaged, but when the shell receives impact force, the shell deforms, the part stored in the shell deviates in posit
