Description

Technical Field

[0001] The utility model relates to the technical field of sensor equipment, in particular to an ultrasonic sensor installation structure. Background Art

[0002] In the existing technology, when installing an ultrasonic sensor, the ultrasonic sensor and the mounting shell are usually potted with hard glue such as epoxy resin. After potting, the hard glue makes the ultrasonic sensor and the mounting shell contact with a large area and tightly connect them into one. However, since the signal of the ultrasonic sensor is easily transmitted through solids when working, when the ultrasonic sensor and the mounting shell contact with a large area and are tightly connected into one, the mounting shell will interfere with the signal of the ultrasonic sensor, affecting the stability of the ultrasonic sensor signal.

[0003] Based on this, the applicant considered designing an ultrasonic sensor mounting structure that can reduce interference to the ultrasonic sensor signal. Utility Model Content

[0004] In view of the above-mentioned deficiencies in the prior art, the technical problem to be solved by the present invention is: how to provide an ultrasonic sensor installation structure that can reduce interference to the ultrasonic sensor signal.

[0008] When installing the ultrasonic sensor body, place it into the mounting groove of the mounting sleeve, and let the bottom side of the ultrasonic sensor body contact the bottom side of the mounting groove, and then fill the sealing hole on the mounting sleeve with sealing material to form a connecting seal that contacts and connects to the bottom side of the ultrasonic sensor body and the mounting sleeve, so that the ultrasonic sensor body and the mounting sleeve are fixedly connected as one; because the connecting seal only contacts and connects to the bottom of the ultrasonic sensor body and the mounting sleeve, the area of ​​close contact between the ultrasonic sensor body and the mounting shell is limited, thereby reducing the interference of solid conduction on the ultrasonic sensor body signal and improving the stability of the ultrasonic sensor body signal.

[0009] Furthermore, the outer side wall of the ultrasonic sensor body and the inner side wall of the mounting sleeve are spaced apart to form a gap.

[0010] Furthermore, an outer wall of the mounting sleeve is provided with an external thread.

The bottom side of the ultrasonic sensor body 100 contacts the bottom side of the mounting groove. A sealing hole 212 is provided on the bottom side of the mounting groove and is connected to the bottom side of the mounting sleeve 210. A connecting seal 300 is encapsulated in the sealing hole 212 and contacts and is connected to the bottom side of the ultrasonic sensor body 100 and the mounting sleeve 210.
