Description

Technical Field

[0001] The utility model relates to the technical field of memory, in particular to a mobile phone memory expansion protective shell. Background Art

[0002] Current mobile phone memory expansion protective cases are equipped with a fixed plug connector so that when the protective case is put on the corresponding mobile phone, the plug connector can be correspondingly plugged into the data interface (charging interface, such as Lightning interface, Type-C interface, micro-USB interface) on the mobile phone. The structure is similar to the Chinese utility model "A mobile phone protective case with storage expansion and backup battery" with publication number CN204741478U, which includes a main shell and a connecting component. The main shell includes a main bottom shell and a main front shell, and the connecting component is fixedly connected to the main bottom shell and the main front shell at the bottom; a backup battery and a control circuit board are fixed on the main bottom shell, and the backup battery is connected to the control circuit board; the connecting component is provided with a plug that matches the USB interface of the mobile phone, and the control circuit board is provided with an SD card socket and a USB interface, and the main front shell is provided with a through hole that matches the plug, and the plug is plugged into the USB interface of the mobile phone through the through hole.

[0003] Because a phone case typically fits snugly around the phone, for example, if the data port is located at the bottom of the phone (where the microphone is located), when putting this type of case on the phone, you first need to tilt the phone relative to the case so that the data port is close to the connector. Then, press firmly until the connector on the case connects to the phone's data port, and then press the phone's frame and back into the case. During this process, because the connector on the case is fixed, when the connector is inserted into the data port, significant friction is generated between the connector and the internal structural components of the data port, causing the connector to tilt.

[0004] Especially when using a strong Kevlar mobile phone case, the deformation buffer of the mobile phone case during the plugging process is small, which can easily cause damage and deformation of the internal structural parts of the plug connector and data interface, thereby easily leading to poor contact.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] See also Figure 1-4 A mobile phone memory expansion protective case includes a protective shell 1 having a mobile phone accommodating slot 2, the mobile phone accommodating slot 2 has an accommodating depth set in a first direction, a mounting cavity 3 is provided on the protective shell 1, and the protective shell 1 has a connecting portion 4 connecting the mobile phone accommodating slot 2 and the mounting cavity 3 in a direction perpendicular to the first direction.

[0024] A mounting frame 5 is installed on the mounting cavity 3, and a first guide rail 6 arranged along a first direction is provided on the mounting frame 5. A first slider 7 is slidingly provided on the first guide rail 6 along the first direction, and a mounting seat 8 is provided on the first slider 7. A plug connector 9 is installed on the mounting seat 8. The plug-in portion of the plug connector 9 passes through the connecting portion 4 and enters the mobile phone receiving slot 2. The connecting portion 4 has a clearance 301 for cooperating with the plug connector 9 to move along the first direction with the first slider 7.

[0025] The installation cavity 3 is provided with a control unit and a data storage module 10. The plug connector 9 is electrically connected to the control unit, and the data storage module 10 is electrically connected to the control unit. The data storage module 10 can be a TF card or a non-volatile storage.

[0026] When the mobile phone memory expansion protective case is put on the mobile phone, the first guide rail 6 and the first slider 7 can slide together to make the position of the plug connector 9 able to be adjusted to a certain extent in the depth direction of the mobile phone accommodating slot 2. The range of position adjustment is determined by the avoidance gap 301 and the guide rail length of the first guide rail 6. That is, when the mobile phone is installed, the plug connector 9 can be moved closer to the opening of the mobile phone accommodating slot 2, so that the data interface of the mobile phone can be more easily plugged into the plug-in part of the plug connector 9, thereby effectively reducing the damage caused by the plug-in.

[0027] After the plug-in portion of the plug connector 9 is connected to the data interface of the mobile phone: under the sliding cooperation of the first guide rail 6 and the first slider 7, the plug connector 9 can move with the mobile phone in the depth direction of the mobile phone receiving slot 2, that is, when the mobile phone is pressed into the mobile phone receiving slot 2, the plug connector 9 can move with the mobile phone in the depth direction, which can effectively avoid resisting the mobile phone from being pressed into place.

[0028] In some embodiments, the plug connector 9 is an OTG plug connector.

[0029] In this embodiment, the mobile phone accommodating slot 2 has an accommodating width set along the second direction and an accommodating length set along the third direction; the connecting portion 4 connects the mobile phone accommodating slot 2 and the mounting cavity 3 along the second direction or along the third direction.

[0030] like Figure 1 As shown, in some embodiments, the connecting portion 4 connects the mobile phone receiving slot 2 and the installation cavity 3 along the third direction.

[0031] In this embodiment, the mounting frame 5 is further provided with a second guide rail 11 arranged along the first direction, and a second slider 12 is slidingly provided on the second guide rail 11 along the first direction; the mounting frame 5 is provided with an elastic return member 13 cooperating with the second slider 12; the mounting seat 8 has an abutting portion 14 abutting against the second slider 12 along the first direction, and is configured such that when the abutting portion 14 presses the second slider 12 along the depth direction of the mobile phone accommodating groove 2, the elastic return member 13 is in a state of elastic deformation or an aggravated elastic deformation state jointly acted upon by the mounting frame 5 and the second slider 12.

[0032] In some embodiments, the elastic return member 13 includes a compression spring located between the second slider 12 and the mounting bracket 5 , and two force-bearing ends of the compression spring abut against the second slider 12 and the mounting bracket 5 respectively.

[0033] like Figure 1-2 As shown, the first direction corresponds to the up-down direction, the mobile phone receiving slot 2 is opened upward, and the connecting portion 4 connects the mobile phone receiving slot 2 and the mounting cavity 3 on the left and right.

[0034] like Figure 3-4 As shown, the second slider 12 is located below the abutment portion 14 of the mounting seat, and the mounting seat 8 can be moved upward and reset by the compression spring, so that when the memory expansion mobile phone case is not equipped with a mobile phone, the plug-in portion of the plug-in connector 9 is close to the upper opening of the mobile phone accommodating slot 2 due to the action of the compression spring. When the mobile phone is installed, there is no need to manually adjust the plug-in connector 9 to the opening close to the mobile phone accommodating slot 2, and alignment is more convenient.

[0035] In some embodiments, the mounting seat and the first slider are rotationally connected or the first slider 7 and the first guide rail 6 are rotationally connected, and the length direction of the virtual rotation center line formed by the rotational connection is the same as the third direction.

[0036] In some embodiments, the first slider 7 is rotatably connected to the first guide rail 6; the first slider 7 is arranged in the shape of a rotating shaft, one end of the first slider 7 cooperates with the first guide rail 6, and the other end of the first slider 7 is connected to the mounting seat.

[0037] like Figure 1 、 3As shown, the third direction corresponds to the front-to-back direction. When the first slider 7 rotates, the plug connector 9 can be flipped up and down accordingly. That is, when the data interface of the mobile phone is plugged into the plug-in part of the plug connector 9, the force applied by the internal structural parts of the data interface to the plug-in part will cause the plug connector 9 to automatically drive the first slider 7 to rotate, that is, the plug connector 9 can be passively rotated to the plug-in angle corresponding to the data interface of the mobile phone, thereby further reducing the damage to the data interface and the plug-in part during the plug-in process.

[0038] like Figure 4 As shown, preferably, the abutting portion 14 includes a retaining abutting portion 141 and a rotating abutting portion 142 .

[0039] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
