Description

Waterproof door assembly and electronic device

Technical Field

The embodiment of the invention relates to the technical field of electronic devices, in particular to a waterproof door assembly and an electronic device.

Background

With the diversity of functions provided by electronic devices, there are often multiple openings in the body of the electronic device to provide wire or expansion device connections. For the purpose of providing water or dust protection for each opening, a door is typically provided at each opening to allow a user to close the opening when not in use.

In many electronic devices with multiple openings, the door covers on the market are structurally designed to connect two door covers to the same pivot, and then lock the pivot between two adjacent openings on the machine body, so as to reduce the number of pivots and the structural space required for installing the door covers. The disadvantage of the above door structure design is that when one of the doors is broken, the two side doors must be replaced at the same time, which results in waste of resources. Furthermore, since each door cover must be designed separately for each type of opening, the existing door cover structure cannot individually design one of the door covers or the opening. For similar models, the probability of single-sided opening design change is much higher than that of double-sided design change, so that design variability is limited, and thus improvement is needed.

In view of the foregoing, there is a need for developing a waterproof door assembly and an electronic device to solve the foregoing problems.

In this way, after the hook 222 of the fastening structure 22 penetrates the opening C132 of the first stop portion C13, the abutment surface C14 between the end surface C131 of the first stop portion C13 and the side cover C1 can limit the displacement of the fastening structure 22 in the axial direction X, so as to improve the stability of the cover plate 10 mounted on the side cover C1. Furthermore, the first end 211 of the axial groove 21 is fastened and fixed with the first stop portion C13 by the fastening structure 22, and the second end 212 of the axial groove 21 can be fastened and fixed by the fixing member 30 to further provide a fixing effect.

In the embodiment of the electronic device with two waterproof door assemblies, since the assembly shafts 20 of the two waterproof door assemblies are connected to the same mounting surface C12, the two waterproof door assemblies connected to the same mounting surface C12 are oriented differently from each other for more fully utilizing the mounting surface C12. In these embodiments, the two watertight door assemblies are rotated 180 degrees, specifically, one watertight door assembly is pivoted 180 degrees around the first radial direction Y1 as the rotation axis, and the other watertight door assembly is oriented. In this way, when the assembling shafts 20 of the two waterproof door assemblies are connected to the same mounting surface C12, the fixing structures 23 of the assembling shafts 20 of the two waterproof door assemblies are alternately arranged on the mounting surface C12 in the axial direction X, and the fixing structure 23 of one waterproof door assembly is adjacent to the fastening structure 22 of the other waterproof door assembly at the same axial direction X.

Preferably, the mounting surface C12 is configured to cooperate with the installation of the aforementioned waterproof door assembly, the first stop portions C13 on the mounting surface C12 are respectively located at different positions in the axial direction X, and each of the first stop portions C13 is adjacent to the second stop portion C15 at the same axial direction X, as shown in fig. 6 and 7. And the first stop part C13 is matched with one of the two waterproof door assemblies, and the second stop part C15 is matched with the other of the two waterproof door assemblies.

When the cover plate 10 is assembled to the side cover C1 through the assembly shaft 20, the recess 24 of the assembly shaft 20 abuts against the abutment surface C1521 of the second stopper C15, and thus the displacement of the assembly shaft 20 in the axial direction X is limited by the second stopper C15, and the stability of the assembly of the cover plate 10 to the side cover C1 through the assembly shaft 20 is improved.

In these embodiments, the second stop portion C15 includes a first portion C151 and a second portion C152 connected, the first portion C151 is connected to the mounting surface C12 of the side cover C1 of the chassis C and extends along the first radial direction Y1, the second portion C152 extends along the second radial direction Y2, and the abutment surface C1521 is located on the second portion C152 and parallel to the abutment surface C14 of the side cover C1.
