Fig. 2 is the schematic diagram for the panorama camera waterproof cover that specific embodiments of the present invention provide.

In figure:

1- front housings, 2- rear shells.

Specific implementation mode

Carry out the various exemplary embodiments of detailed description of the present invention now with reference to attached drawing.It should be noted that:Unless in addition having Body illustrates that the unlimited system of component and the positioned opposite of step, numerical expression and the numerical value otherwise illustrated in these embodiments is originally The range of invention.

It is illustrative to the description only actually of at least one exemplary embodiment below, is never used as to the present invention And its application or any restrictions that use.

Technology, method and apparatus known to person of ordinary skill in the relevant may be not discussed in detail, but suitable In the case of, the technology, method and apparatus should be considered as part of specification.

In shown here and discussion all examples, any occurrence should be construed as merely illustrative, without It is as limitation.Therefore, other examples of exemplary embodiment can have different values.

It should be noted that:Similar label and letter indicate similar terms in following attached drawing, therefore, once a certain Xiang Yi It is defined, then it need not be further discussed in subsequent attached drawing in a attached drawing.

The present invention provides a kind of air tightness testing methods of box body, and box body is enclosed by multiple shells, and is formed with Cavity.

As shown in Figure 1, first carrying out air tightness test one by one to multiple shells, wait for that the air tightness test of each shell is qualified Afterwards, multiple shells are assemblied together to form box body, air tightness test then is carried out to the box body that assembling is formed.If the gas of box body Close property test result reaches preset requirement, then judges that the air-tightness of box body is qualified;Otherwise, judge that the air-tightness of box body is unqualified.

The air tightness testing method of box body provided by the invention can avoid using the underproof shell assembling box of air-tightness Body can directly exclude the underproof situation of shell air-tightness, more quickly determine that box when box body air-tightness is unqualified The underproof position of body air-tightness, improves the production efficiency of product.

Specifically, when carrying out air tightness test one by one to shell, first each shell is cooperatively formed with detection piece respectively Cavity, then carries out air tightness test to the cavity of formation, and whether the air-tightness to judge shell is qualified.Wherein, detection piece Air-tightness can reach preset requirement, the air-tightness of the connecting portion after detection piece and shell cooperation can reach default and want It asks, avoids having an impact the air tightness test result of shell.

In one embodiment, the link position of shell and detection piece is provided with fluid sealant, and fluid sealant is for filling and close Gap between capsule body and detection piece can make the air-tightness of the connecting portion of shell and detection piece reach preset requirement.It can Selection of land, fluid sealant are silica gel, and silica gel has good sealing performance, will not be damaged to the outer surface of shell, are completed in test After easily remove.Those skilled in the art can also choose other kinds of fluid sealant, and the present invention is without limitation.

In one embodiment, the link position of shell and detection piece is provided with rubber ring.Rubber ring has good shape Change ability can make the link position air-tightness of shell and detection piece reach pre- after the common extruding by shell and detection piece If it is required that.In addition, rubber ring cost is relatively low, it is relatively durable and easy to use.Those skilled in the art can also choose shell with Other sealing means of the connecting portion of detection piece, every scheme that can reach similar technology effect belong to the guarantor of the present invention Protect range.

In one embodiment, further include having detection device when carrying out air tightness test one by one to shell, detection device packet It includes and the structure of multiple shells multiple imitation shape pieces correspondingly.When carrying out air tightness test one by one to shell, remaining shell Imitation shape piece form detection piece.The imitation shape piece of each shell and remaining shell cooperatively forms cavity, then to the cavity of formation into Row air tightness test.Air tightness test is carried out using the cooperation of the imitation shape piece of shell and other shells, test result can be improved Accuracy.Wherein, imitation shape piece is an integral structure, and any through-hole is not present, and air-tightness is configured to reach to preset and want It asks.Specifically, the air-tightness of the link position between the link position between imitation shape piece and shell, imitation shape piece and imitation shape piece is in shell Body can reach preset air-tightness requirement when being detected, avoid having an impact shell air tightness test result.

In one embodiment, to being completed box body carry out air tightness test the step of in, provide babinet and The air-tightness of standard component identical with box body volume, the standard component can reach preset requirement.Wherein, there are two babinet settings, Standard component and box body are individually positioned in two air-tightness to reach in preset requirement and the identical babinet of chamber portions, then It is filled with same amount of gas simultaneously in two babinets, for example, the gas of same volume.After preset time, two are checked The air pressure of babinet, if the air pressure of two babinets is equal or difference within a preset range, judge that the air tightness test of box body closes Lattice, on the contrary, judging that the air tightness test of box body is unqualified.

Optionally, air gauge can be respectively set on two babinets, for the real-time atmospheric pressure value in show case body, conveniently looks into It sees.Skilled person can also choose other and obtain babinet others form, and the present invention is without limitation.

Optionally, the gas for being used for filling box body cavity body can be that air, nitrogen or other gases, the present invention do not do this Limitation.

In one embodiment, there are one babinet settings, the air-tightness of standard component and shell is carried out respectively using babinet Test is filled with the gas of same volume, the air pressure of test result twice is compared after the completion of test twice in test process middle case Numerical value.The air pressure numerical value of test result is equal twice or difference within a preset range, then judge that the air tightness test of box body is qualified, On the contrary, judging that the air tightness test of box body is unqualified.

Optionally, standard component is metal derby, and metal derby has good air-tightness, can improve box body air tightness test knot The accuracy of fruit.Wherein, metal derby can be copper billet, aluminium block etc., and those skilled in the art can also choose other kinds of mark Quasi- part, the present invention are without limitation.

The present invention also provides a kind of air tightness testing methods of panorama camera waterproof cover, as shown in Fig. 2, waterproof cover includes Front housing 1 and rear shell 2, the front housing 1 are both provided with the mounting hole for installing panorama camera other component with rear shell 2, work as mounting hole After the corresponding part of fit on, the air-tightness of mounting hole is tested using above-mentioned air tightness testing method.

Although some specific embodiments of the present invention are described in detail by example, the skill of this field Art personnel it should be understood that example above merely to illustrating, the range being not intended to be limiting of the invention.The skill of this field Art personnel are it should be understood that can without departing from the scope and spirit of the present invention modify to above example.This hair Bright range is defined by the following claims.
