Description

Technical Field

[0001] The utility model relates to the technical field of mounting piece structures, in particular to a mounting piece structure of a speed sensor. Background Art

[0002] The velocity sensor is a sensor that can measure acceleration. It is usually composed of a mass block, a damper, an elastic element, a sensitive element, and an adaptive circuit. During the acceleration process, the sensor measures the inertial force exerted on the mass block. Therefore, a mounting structure for the velocity sensor is required.

[0003] According to the description of a speed sensor installation structure disclosed in the patent website (authorization announcement number: CN 211528449U), "The utility model discloses a speed sensor installation structure. It includes a fixed seat, a vertical through hole for fixing the speed sensor is provided on the fixed seat, and ears are symmetrically provided on both sides of the fixed seat, and mounting holes are provided on the ears, and the mounting holes are arranged horizontally. The utility model has a simple structure and a reasonable design. One end of the through hole of the fixed seat faces the radial direction of the motor, that is, the mounting hole is installed along the axial direction of the motor, thereby reducing the installation space required for the radial direction of the motor. The double-installation hole design makes the speed sensor installation more stable and improves the measurement accuracy. The installation direction mark avoids the situation where the fixed seat and the installation direction are wrong."

At this time, the mounting hole is set along the axial direction of the motor rotor, and the fixing base is fixed to the motor through the mounting hole. Since the angle of the device is fixed, it is difficult to accurately adjust the angle of the sensor, which affects the use of the sensor. Utility Model Content
