Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the present invention, it should be noted that the terms "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. are all based on the orientation or position relationship shown in the drawings, and are only for convenience of description and simplification of the present invention, but do not indicate or imply that the device or element of the present invention must have a specific orientation, and thus, should not be construed as limiting the present invention.

Example 1

Referring to fig. 1 and 2, the present invention discloses a waterproof mobile phone shell, which includes a hard rear shell 1, a soft middle shell 2, a hard front shell 3, a buckle 4 and a hanging plate 5.

Referring to fig. 2, the hard back shell 1 has a first receiving cavity 11 for receiving the soft middle shell 2. The soft middle shell 2 has a second accommodating cavity 21 for accommodating the mobile phone. The edge of the soft middle shell 2 has an extended side to form a first sealing part 22, and the edge of the soft middle shell 2 has an extended side to form a second sealing part 23. The rigid front shell has a transparent operating window 31 for operating the screen of the handset.

When the hard front shell 3 is fastened with the hard rear shell 1, the first sealing part 22 seals the joint of the hard front shell 3 and the hard rear shell 3 to play a role of first resealing; the second sealing portion 23 abuts against the inner cavity of the hard front case 3 to perform a second resealing.

Referring to fig. 3, the hard front shell 3 is provided with an embossed groove 32 at a contact area with the first sealing portion 22 for accommodating deformation generated by the pressed first sealing portion to ensure a sealing effect.

Referring to fig. 3 and 4, the bottom of the second accommodating cavity 21 has a plurality of integrally formed non-solid protrusions 24, in this embodiment, the non-solid protrusions 24 are formed by recessing the bottom of the soft middle shell 2. It is required to ensure that H1 is greater than H2, H1 is the sum of the protrusion height of the non-solid protrusion 24 and the thickness of the mobile phone to be accommodated, and H2 is the height from the bottom of the second accommodating cavity 21 to the inner plane of the transparent operating window 31 when the rigid rear shell 1 is fastened to the rigid front shell 3, so that the screen of the mobile phone can be attached to the transparent operating window 31 under the action of the non-solid protrusion 24 when the mobile phone is installed.

In this embodiment, the number of the non-solid protrusions 24 is four (if too few, the non-solid protrusions are not enough to support, if too much, the resistance may be too large when the hard front shell 3 and the hard rear shell are fastened together), and the protrusions are distributed on two central lines of the soft middle shell 2 in a diamond shape, so as to ensure uniform support of the mobile phone.

Referring to fig. 2 and 3, the hard rear case 1 has a hinge portion 12 at one side and a fastening portion 13 at the other side. One side of the hard front shell 3 is hinged on the hinge part 12, the other side of the hard front shell 3 is hinged with the buckle 4, and the buckle 4 is buckled on the buckling part 13.

In this embodiment, there are two fastening portions 13. Along the edge of the hard back shell 1, the hard back shell 1 has a first positioning groove 14 extending from the outward end of one fastening portion 13 (the outward end is defined as the direction departing from the center of the shell along the length) to the outward end of the other fastening portion 13. The spacing area 15 of the two buckling parts 13 is provided with a second positioning slot 16. In order to reduce the width of the mobile phone case, in the embodiment, the two fastening portions 13 are designed to be concave, so that the corresponding first sealing portion 21 is narrower, and the area needs to be specially designed to avoid displacement.

Referring to fig. 2 and 4, the inner sides of the two fastening portions 13 are provided with third positioning protrusions 17. The bottom of the extension edge of the soft middle shell 2 is provided with a first positioning bulge 25 and a second positioning bulge 26 which respectively correspond to the first positioning groove 14 and the second positioning groove 16, and the bottom of the soft middle shell 2 is provided with a third positioning groove 27 which corresponds to the third positioning bulge 17.

Soft mesochite 2 and preceding shell 3 of stereoplasm are in the position that corresponds to the cell-phone interface of charging to piecing together and form an interface 6 that charges, and interface 6 that charges forms a seal groove 61 on its chamber wall, is equipped with the interface 18 of stepping down corresponding to interface 61 that charges on the stereoplasm backshell 1. The outer contour of the plug 28 is adapted to the cavity wall of the charging interface 6, and the plug 28 is provided along its outer contour with a third sealing portion 281 corresponding to the sealing groove 61.

The plug 28 is connected to the soft middle shell 2 by a flexible strip 29. The plug 28, the flexible band 29 and the soft middle shell 2 can be integrally formed, but the disadvantage is that the flexible band 29 is easily broken at the connection part of the flexible band 29 and the plug 28 or the connection part of the flexible band 29 and the soft middle shell 2 when the plug 28 is pulled for a long time. Therefore, it is also possible to embed a first hard block (metal block or hard plastic) in the soft middle shell 2 by two-shot molding, embed a second hard block in the outward side of the plug 28, and then connect the first hard block and the second hard block by a flexible band (e.g., steel wire or wool rope).

Referring to fig. 5, the hard rear shell 1 has a concave portion 19 in the central area of the shell, a plurality of convex buttons are disposed in the concave portion 19 for connecting the hanging plate 5, a plurality of hanging grooves 51 with the same orientation are disposed on the hanging plate 5, each hanging groove 51 is big in the top and small in the bottom, and a fastening groove 52 is disposed on the inner wall of the small end, so that when a hanging piece corresponding to the small end of the hanging groove 51 is disposed at the target hanging position, the hanging piece can enter from the big end of the hanging groove 51, and then the mobile phone can be vertically pressed downward to fasten the hanging groove 51.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
