Detailed ways

In order to fully understand the purpose, features and effects of the present invention, the present invention will be described in detail by means of the following specific embodiments and accompanying drawings, as follows:

Referring to FIG. 2 , it is a flow chart of the waterproof method according to the first embodiment of the present invention. In FIG. 2, the waterproof method is used for an electronic device having a first casing and a second casing, and the first casing has a first edge for engaging a second edge of the second casing, the waterproof method Including: forming a protrusion around the first edge on the first housing, that is, the protrusion surrounds a part of the periphery of the first housing, and is formed on the second housing A concave portion surrounding the second edge and corresponding to the protruding portion; then, an elastic unit is provided in the concave portion, the elastic unit has a body and a soft interference body protruding from the body, wherein the cross section of the body can be quadrilateral or rectangle, and the soft interference body is a pyramid, and the pyramid in the above can be defined as a solid cone whose bottom is polygonal and each side of the polygon extends to a common point; then, join the first edge and the The second edge is used to make the protruding part press the soft interference body to deform to form the first interference structure.

In other words, through the present invention, when the soft interference body of the elastic unit is first pressed by the protrusion, the soft interference body of the elastic unit is deformed in the concave portion, and due to the soft interference body The size of is relatively small, so the reaction force generated by its deformation is not enough to deform the first edge of the first shell.

When the protruding portion of the first housing moves and squeezes toward the soft interference body and the body by applying a downward pressing force, the soft interference body first bears the downward force and deforms ; Then, the deformed soft interfering body indirectly transmits the downward force to the main body again, so that the main body is also deformed. It is worth noting that the soft interfering body effectively disperses the downward force, and the body indirectly affected, after deformation, does not affect the first edge and the second edge combined.

In addition, according to the design of the protruding portion, in addition to squeezing the soft interference body, the body of the elastic unit can also be further squeezed to cause deformation. However, since the cross-section of the body is quadrangular or rectangular, the protrusion can apply pressure on the body to produce uniform deformation, and the corresponding reaction force can be evenly applied to the joints of the shell to avoid shell deformation. The deformation of the body joints leads to poor waterproof and dustproof effects.

The soft interference bodies in this embodiment can be plural, respectively protruding on the surface of the main body, and when the first edge joins the second edge, the protrusions press the soft interference bodies to form a plurality of first interference structure. The number of soft interference bodies can be designed according to user needs.

Referring to FIG. 3 , it is a flow chart of the waterproof method according to the second embodiment of the present invention. In FIG. 3 , in addition to the above-mentioned waterproof method of the first embodiment, it further includes forming a hard interference body on the protrusion, and when the first edge and the second edge are joined, the hard interference body is squeezed. Pressing and positioning the body of the elastic unit causes deformation to form a second interference structure.

In this embodiment, the soft interference body and the hard interference body are asymmetrically disposed on the protrusion and the recess, respectively. In other words, one end of the protrusion has a protruding hard interference body, and the hard interference body may be formed at a position that does not correspond to the soft interference body. When the first edge of the first shell is engaged with the second edge of the second shell, the hard interference body can compress the body of the elastic unit to cause deformation, and the hard interference body squeezes Where the body is pressed, a second interference structure different from the first interference structure can be formed. Wherein, the second interference structure can further provide a further waterproof effect. In addition, the hard interference structure can also provide the body positioning effect by extrusion. It should be noted that the hard interference body is not limited to any shape, that is, the hard interference body only needs to protrude from the protruding portion, which belongs to the scope of the hard interference structure of the present invention.

4a and 4b are schematic cross-sectional views of a waterproof structure according to a third embodiment of the present invention. In FIG. 4a, the waterproof structure 10 is used in an electronic device with a first housing 12 and a second housing 14. Please note that the first housing 12 and the second housing 14 in the drawing only show the two The sectional view of the joining portion does not show the whole of the first housing 12 and the second housing 14 . The first shell 12 has a first edge 122 for engaging the second edge 142 of the second shell 14 . The waterproof structure 10 includes a protruding portion 16 , a concave portion 18 and an elastic unit 20 . The protrusion 16 is formed on the first housing 12 around the first edge 122; the recess 18 is formed on the second housing 14 around the second edge 142, and the recess 18 corresponds to the protrusion. and, the elastic unit 20 is disposed along the recess 18 , the elastic unit 20 has a body 202 and a soft interference body 204 , and the soft interference body 204 protrudes from the body 202 . The cross section of the body 202 of the elastic unit 20 can be quadrilateral or rectangular, and the soft interference body 204 can be a pyramid. In this embodiment, the body 202 is described by taking a rectangular body as an example. In another embodiment, the body 202 and the soft interference body 204 are made of rubber. Furthermore, when the first edge 122 engages the second edge 142 , the protrusion 16 is accommodated in the recess 18 and presses the soft interference body 204 to deform to form a first interference structure.

Referring next to FIG. 4b, when the first housing 12 of FIG. 4a is engaged with the second housing 14, the protrusion 16 surrounding the first edge 122 provided on the first housing 12 is inserted into the same Surrounding the recess 18 formed on the second edge 142 of the second housing 14 , and pressing the soft interference body 204 of the elastic unit 16 . It is worth noting that the soft interference body 204 of the elastic unit 20 is first subjected to the force F applied by the protrusion 16, and the soft interference body 204 is deformed due to the downward force F, And further pressing the body 202 causes the body 202 to deform in the concave portion 142 as well. The soft interference body 204 and the main body 202 , the protruding portion 16 and the concave portion 18 are in contact with and pressed against each other to form a first interference structure, thereby providing a waterproof function. Furthermore, since the deformation of the soft interference body 204 is relatively small when subjected to the acting force F, the deformation of the housing due to excessive reaction force F' applied to the protruding portion 16 will not occur. Through the waterproof structure with the first interference structure of the present invention, it can make it Still retains its waterproof structure.

5a and 5b are cross-sectional schematic diagrams of a waterproof structure according to a fourth embodiment of the present invention. In FIG. 5a, the waterproof structure 10' is used for an electronic device having a first housing 12 and a second housing 14, and the first housing 12 has a first edge 122 for engaging the second housing 14. The second edge 142 includes the same protruding portion 16 , concave portion 18 and elastic unit 20 as those of the previous embodiment. Wherein, the first housing 12 further includes a hard interference body 124, and the hard interference body 124 protrudes from the protruding portion 16, and when the first edge 122 engages the second edge 142, the The hard interference body 124 and the soft interference body 204 are asymmetrically disposed on the protruding portion 16 and the body 20 respectively. It should be noted that the hard interference body 124 is not limited to any shape, and it only needs to protrude from the protruding portion 16 to belong to the hard interference body 124 of the present invention.

Referring next to FIG. 5b, when the first housing 12 is combined with the second housing 14, the protruding portion 16 that is circumferentially disposed on the first edge 122 of the first housing 12 is inserted into the same circumferentially disposed portion of the first housing 12. The soft interference body 204 of the elastic unit 20 is pressed into the recess 142 of the second edge 142 of the second housing 14 . Here, the soft interference body 204 of the elastic unit 20 is deformed upon receiving the force F applied to the protruding portion 16 , and at the same time, the hard interfering body located at the protruding portion 16 124 is pressed against the body 202 of the elastic unit 20, that is, the body 202 and the soft interference body 204 respectively bear the downward force F from the hard interference body 124 and the protrusion 16 , and make the body 202 deform in the concave portion 18 . The hard interference body 124 and the main body 202 are in contact with each other and pressed to form a second interference structure, thereby providing a waterproof function. It is worth noting that, since the hard interfering body 124 in this embodiment is relatively small, the amount of deformation of the body 202 caused by the extrusion of the body 202 is small, so the body 202 will not exert excessive reaction force. F' causes deformation of the housing due to the hard interference body 124 . In addition, since the hard interfering body 124 partially presses the body 202 , it can provide an effect of positioning the body 202 .

To sum up, through the above-mentioned first interference structure and second interference structure, the waterproof structure of the present invention does not reduce the overall waterproof effect due to the deformation of the seam of the shell due to excessive application of reaction force on the shell, and also It can further effectively improve and strengthen the waterproof effect.
