Description
Technical field
The utility model is related to a kind of component devices of ultrasonic sensor, and in particular to a kind of ultrasonic sensor metal
Shell, the utility model further relate to a kind of ultrasonic sensor, belong to range measurement and signal device field more particularly to automobile
Auxiliary park, in automatic parking and traveling be used for range measurement a kind of ultrasonic sensor.
Background technology
Previous ultrasonic sensor metallic shell structure is as shown in Figure 2,3, prior art ultrasonic sensor metal-back
2 shape of body is cylindrical, and internal cavity corresponds to ultrasonic sensor vertical direction similar to a kidney-shaped, the shape longer sides 21
Directive property, shorter edge 22 correspond to ultrasonic sensor horizontal direction directive property；Referred in the working frequency of ultrasonic sensor
After fixed, the sole mode of adjustment either vertically or horizontally direction directive property be exactly adjust 2 internal cavity longer sides 21 of metal shell or
The size of person's shorter edge 22, their corresponding relationships are：Size is bigger, and directive property is smaller, conversely, directive property is bigger；And it is usual
In usage scenario, it is expected that the directive property of the vertical direction of ultrasonic sensor is more the smaller the better, this just needs to correspond to Vertical Square
To the size bigger of the longer sides 21 of directive property, but since the overall diameter 23 of prior art ultrasonic sensor metal shell 2 is
Determining, increase the size of longer sides 21,2 vertical direction side wall 24 of prior art ultrasonic sensor metal shell will necessarily be made
Thickness is thinned, and reduces the anti-extrusion ability of prior art ultrasonic sensor metal shell 2, influences the use of ultrasonic sensor
Service life.
Utility model content
The purpose of the utility model is to overcome the deficiencies in the prior art, provide a kind of ultrasonic sensor metal shell,
The anti-extrusion ability of metal shell will not can be significantly reduced under conditions of meeting vertical direction directive property and becoming smaller.
The utility model is realized in this way：
A kind of ultrasonic sensor metal shell, external cylindrical, internal cavity is similar to a kidney-shaped, in internal cavity
An inside groove is arranged in bottom length direction.
Further scheme is：
The diameter of inside groove is less than the overall diameter of metal shell, the simultaneously greater than ruler of the inner cavity longer sides of metal shell
It is very little.
The utility model additionally provides a kind of ultrasonic sensor, has used metal shell disclosed by the utility model.
Ultrasonic sensor has conventional structure composition, generally comprises metal shell, piezoelectric ceramic piece, electric wire, connection
Device and other fillers.
The utility model has the advantages that：
One inside groove is set in sonac metal shell intracavity bottom length direction side, passes through the diameter of groove
Control the directive property of vertical direction, the original longer sides size in metal shell inner cavity is then not necessarily to consider that it is directed toward vertical direction
Property influence, function change into improve metal shell anti-extrusion ability；Therefore so that can be in the overall diameter of metal shell
On size basis, the maximized diameter for increasing groove reduces the directive property of vertical direction, and metal-back in this way
The anti-extrusion ability of body can't reduce, or even have an opportunity to enhance.

Specific implementation mode
The utility model is further understood for the ease of those skilled in the art, and clearly understanding the application institute
The technical solution of record, the relevant technologies content that is complete, fully disclosing the utility model are new to this practicality below in conjunction with the accompanying drawings
The specific implementation mode of type is described in detail, it should be apparent that, described specific implementation mode is only in a manner of enumerating
The a part of the embodiment for giving the utility model is used to help understand the utility model and its core concept.
Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
The all other embodiment obtained, or without departing substantially from the spirit of the present invention and its essence, even if to each portion
The connection relation or structure divided are changed, and make various corresponding change and deformations, but this according to the utility model
A little corresponding change and deformations should all belong to the range of the utility model protection
It should be noted that the contents such as information exchange, implementation procedure between each unit in above-mentioned apparatus and system, by
In being based on same design with the utility model embodiment, particular content can be found in the narration in the utility model method embodiment, this
Place repeats no more.
The utility model is related to relational language be described as follows：
Directive property：Sound source forms the pencil sound wave for concentrating transmitting in a certain direction, evaluates pencil sound wave angle of divergence size
Parameter.
The basic technology scheme of the utility model is as follows：
The utility model provides a kind of ultrasonic sensor, including metal shell, piezoelectric ceramic piece, electric wire, connector and
Other fillers form, it is characterized in that sonac metal shell intracavity bottom length direction side be arranged one it is inside recessed
Slot adjusts the directive property of vertical direction by adjusting the diameter of groove, and the size of original metal shell longer sides is less than recessed
The diameter of slot, the anti-extrusion ability for promoting metal shell.
The specific implementation of the utility model is as follows：
Embodiment one：
As shown in Fig. 1, be the utility model first embodiment ultrasonic sensor cross-sectional cut-away stereogram.It is attached
Fig. 4 is the vertical view and sectional view of the utility model ultrasonic sensor metal shell 1.In the ultrasonic sensor of the present embodiment
In metal shell 1, metal shell intracavity bottom length direction increases an inside groove 11, at this time by adjusting the diameter of groove
12 change the directive property of ultrasonic sensor vertical direction, and the size 14 of metal shell inner cavity longer sides can be set as it is small
In the diameter 12 of groove, to improve the crush resistance strength of metal shell, it is obvious that the diameter 12 of groove is less than the outer of metal shell
Diameter 13.
It is a feature of the present invention that metal shell intracavity bottom length direction increases an inside groove, by adjusting recessed
Slot diameter changes the directive property of vertical direction.The reason of using the structure, is as follows：
Table 1 embodies directive property of the utility model ultrasonic sensor metal shell under different sizes and it anti-is squeezed
Compressive Strength.Table 2 embodies directive property and its crush resistance strength of the previous ultrasonic sensor metal shell under different sizes.
Two groups of data comparisons can see, in metal shell overall diameter all in 14mm when, for the previous metal shell of un-grooved, need
The numerical value for reducing directive property, then must improve the size of metal shell longer sides, but provide but also metal shell it is anti-extrusion
Strength reduction；For the utility model ultrasonic sensor metal shell, the numerical value for reducing directive property is needed only to need adjustment bottom
The size of the diameter of groove, former longer sides can remain unchanged, therefore the crush resistance strength of metal shell greatly promotes.
Directive property and its crush resistance strength of the 1 the utility model ultrasonic sensor metal shell of table under different sizes
Directive property and its crush resistance strength of the 2 previous ultrasonic sensor metal shell of table under different sizes
