The utility model discloses simple structure firmly, not fragile, support dismouting many times, manufacturing cost and maintenance cost low.
Description
Technical field
The utility model relates to vehicle monitoring technical field, particularly a kind of monitoring device for monitoring fuel tank fuel quantity.
Background technology
The monitoring device of existing fuel tank fuel quantity comprises ultrasonic probe and primary control box, ultrasonic probe is connected with primary control box by cable, ultrasonic probe is arranged on mailbox by adhesive-layer, its major defect existed is: adhesive-layer causes whole ultrasonic probe to be scrapped by after external force breakage, adds maintenance cost; Ultrasonic probe and the discrete setting of primary control box, production cost is high.
Utility model content
The purpose of this utility model is to provide a kind of fuel tank fuel quantity monitoring device, and its structure is simple firmly, not fragile, support being dismounted for multiple times, production cost and maintenance cost is low.
For achieving the above object, the utility model is by the following technical solutions:
A kind of fuel tank fuel quantity monitoring device, comprise open-topped housing, the ultrasonic listening assembly of transceiver and main control board, described housing adopts metal material to be made of one piece, described ultrasonic listening assembly is located on the interior diapire of described housing, described main control board to be located in described housing and to be positioned at the top of described ultrasonic listening assembly, and seal with casting glue, described main control board and described ultrasonic listening assembly are electrically connected.
Preferably, described main control board is integrated is provided with acceleration transducer.
Preferably, described ultrasonic listening assembly adopts piezoelectric ceramic piece, and it is adhered on the interior diapire of described housing.
Preferably, described housing is cylindric, is provided with chamfering bottom it.
Preferably, the top of described housing offers two symmetrical through holes, is equipped with a hollow stem between two described through holes.
Preferably, the outer wall of described housing offers two symmetrical draw-in grooves.
Preferably, described housing adopts aluminum alloy materials to make.
After adopting technique scheme, the utility model is compared with background technology, and tool has the following advantages:
1, the utility model adopts all-metal housing, and whole probe will be scrapped because glue power is damaged when meeting external force (as bumping against), maintenance cost is low.
2, the utility model adopts integrated structure, reduces production cost.
3, main control board is integrated is provided with acceleration transducer, can be used for judging the static or motion state of fuel tank and static time inclination angle, and then revise measured deviation.
4, the top of housing is equipped with hollow stem, is convenient to penetrate iron wire on the one hand and is fixed on fuel tank by housing, and when glue-line loses efficacy, housing can not depart from tank surface and cause probe breakage, added the intensity of housing on the other hand.
5, the bottom of housing offers chamfering, is convenient to, by glue, housing is fixed on tank surface, improves the firmness that housing is combined with fuel tank.
The outer wall of 6, housing offers two symmetrical draw-in grooves, be convenient to utilize the instruments such as spanner to be removed from tank surface by housing, make dismounting very convenient.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
