Abstract
The utility model relates to a ultrasonic sensor casing belonging to the reflection positioning or detection field adopting radio wave. The interior of the ultrasonic sensor casing is a cavity which encloses a sensor probe by silicon rubber and plastic member. The external surface of the sensor casing is a cylindrical surface, one end of which is provided with an annular groove capable of blocking the ultrasonic wave radiation of the side vertical direction of the sensor probe. The utility model is easy to be processed, capable of blocking the radiation signal from the side vertical direction of the sensor probe and improving the quality of the ultrasonic sensor which is free of distort.
Description
Technical field
The utility model ultrasonic sensor shell belongs to and adopts radio wave reflection location or detection range, particularly relate to a kind ofly be used to detect, the housing of the ultrasonic sensor of Measuring Object distance.
Background technology
The radiate supersonic wave pulse of existing ultrasonic sensor discontinuity, and detection is measured and the distance of object, sensor probe is installed in the shell of cavity, by silicon rubber and plastic parts encapsulation, because shell is the face of cylinder, under the influence of silicon rubber and plastic parts, the sensor probe Signal Spacing effect that radiates of vertical direction from the side weakens, thereby cause sensor very easily to visit the signal that side radiates to vertical direction from the side, influence hyperacoustic radiation scope and sensing range, the ultrasonic sensor that on radar for backing car, uses acceptant to from ground or other do not influence the barrier of reversing and cause the wrong report of radar for backing car.
The content of utility model
The purpose of this utility model is to avoid weak point of the prior art and a kind of signal that the side vertical direction radiates of isolating is provided, prevent that ultrasonic sensor from accepting the signal that vertical direction from the side radiates, control the ultrasonic sensor shell of hyperacoustic radiation scope and sensing range.
The purpose of this utility model reaches by following measure, the ultrasonic sensor enclosure is a cavity, at outer surface of outer cover is a face of cylinder, sensor probe is encapsulated in the cavity of enclosure by silicon rubber and plastic parts, one end outside surface of sensor outer housing is provided with the groove of an annular, the groove of annular can be blocked the ultrasound wave radiation of sensor probe lateral vertical direction, guarantees that sensor probe does not detect the ultrasound wave radiation of lateral vertical direction at work.
When on radar for backing car, using, outside surface that can sensor outer housing is provided with surface platform, a hole is arranged on surface platform, a screw rod is installed in the hole, the front end outside surface of sensor outer housing is provided with location-plate, adopts a bit and fixes, and can guarantee former car " injury " minimum, adopt common drill bit to get final product, and do not need specialized equipment.The center that screw rod is is a through hole, intracardiac sky in the screw rod, and sensor signal lines is directly connected to main frame by the screw rod endoporus.
The utility model handling ease, the isolation sensor signal that vertical direction from the side radiates of popping one's head in guarantees that sensor probe reports by mistake at work, improves the quality of ultrasonic sensor.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model.
Accompanying drawing 2 is structural representations of the present utility model.
Accompanying drawing 3 is example structure synoptic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Shown in accompanying drawing 1, accompanying drawing 2, ultrasonic sensor shell of the present utility model 1 inside is cavity, at outer surface of outer cover is a face of cylinder, the platform 2 that two symmetries are arranged on the face of cylinder, platform is provided with mounting hole, the ring that protrusion is arranged on an end face of ultrasonic sensor shell, the outside surface of sensor outer housing is provided with the groove 3 of an annular, the outside surface junction of ring that groove protrudes on end face and sensor outer housing, wide 0.1～the 3mm of groove, deeply greater than 0.1mm, can in ring groove, fill insulating paper, also can filled silicon rubber etc.When ultrasonic sensor shell of the present utility model used on radar for backing car, the influence that the vertical direction from the side of can effective isolation popping one's head in radiates guaranteed that radar for backing car does not detect ground or other at work and do not influence the barrier of reversing and report by mistake.
As shown in Figure 3, ultrasonic sensor shell of the present utility model 1 inside is cavity, the ring that protrusion is arranged on an end face of ultrasonic sensor shell, the outside surface of sensor outer housing is provided with the groove 3 of an annular, the outside surface junction of ring that groove protrudes on end face and sensor outer housing, wide 0.1～the 3mm of groove, deeply greater than 0.1mm, filling out in the ring groove can filled silicon rubber etc.
