Description

Technical Field

[0001] This utility model relates to the field of memory technology, and in particular to a multifunctional expandable memory. Background Technology

[0002] Currently, there are various types of expandable storage devices for mobile phones, such as flash drives that can be directly plugged into the phone, and phone cases with built-in memory. Phone cases with built-in memory can be plugged into the phone to expand its memory. Some phone cases with built-in memory can also house a battery for power supply, such as the Chinese utility model "A Protective Case with Storage Expansion and Backup Battery" (CN204741478U); and some, in addition to a battery, also include a display module to indicate the operating status, such as the Chinese invention "A Mobile Expansion Device" (CN105305550B). The light guide is also equipped with multiple LEDs, which are used to indicate the status information of the mobile expansion device.

[0003] However, the aforementioned phone case-type expandable storage devices with display modules and batteries have their indicator lights located on the back or side of the case, making it inconvenient for users to view the displayed information while using the phone. Furthermore, the expandable storage devices with these multiple functions, once installed with the phone, are significantly heavier than the phone itself. Holding the phone case requires applying force at multiple points for stability. Some users, while holding the edge of the case, will press their thumb against the phone screen for added stability. While this method is suitable for operating the phone (such as swiping), when the user is simply holding the phone for reading text or watching videos, the thumb pressing on the screen can lead to accidental touches and excessively obstructs the screen, significantly reducing the viewing experience. Utility Model Content

[0004] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the problem of inconvenient viewing angles for multi-functional mobile phone case-type expandable storage devices, as well as the problem of reduced visual experience caused by users pressing their thumbs against the phone screen for stable grip due to increased overall weight.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional expandable storage device, including a protective shell, a mobile phone receiving groove formed on the front of the protective shell, an installation cavity inside the protective shell, a first plug-in connection port communicating with the mobile phone receiving groove, and a second plug-in connection port communicating with the installation cavity on the outer side of the protective shell; a battery module, a data storage module, a processor, an electrical connection connector for plugging into a user's mobile phone through the plug-in connection port, and an electrical connection interface near and corresponding to the second plug-in connection port are provided inside the installation cavity; a shell-end display screen electrically connected to the processor is also installed on the front of the protective shell, and the shell-end display screen is arranged side by side with the front groove of the mobile phone receiving groove along the direction in which the electrical connection connector is inserted into the user's mobile phone.

[0006] The usage information of this multi-functional expansion memory can be viewed in a timely manner through the display screen on the front of the casing.

[0007] When a user holds the protective case: If the user does not wish to hold the phone stably by pressing their fingers against the front of the phone, and cannot hold the phone stably by simply holding the edge of the protective case, the user can choose to press some of their fingers against the screen on the case, which is an additional grip area relative to the phone. For example, the user can press their thumb against the screen on the case and hold the edge of the protective case with their hand, thus making the grip more stable, and maintaining stability in both landscape and portrait orientations.

[0008] Especially when the phone being installed has a full-screen display or a high screen ratio, pressing directly on the phone screen can easily lead to accidental triggering of operation commands. The additional grip area formed by the screen on the casing can solve the problems of accidental phone operation and significant obstruction of the phone screen caused by the traditional method of pressing on the phone screen while maintaining a stable grip.

[0009] As a further aspect of this invention: the electrical connector is inserted into the user's mobile phone in the direction corresponding to the length of the phone. This avoids excessively increasing the overall width, preventing increased difficulty in one-handed holding, and is compatible with most mobile phones.

[0010] As a further improvement of this invention: in the projection of the protective shell in the front and back directions, the display screen at the shell end at least partially overlaps with the mounting cavity. This results in a smaller overall footprint.

[0011] As a further aspect of this invention: the edge of the front of the protective housing protrudes forward to form a protective ridge, and the area enclosed by the protective ridge includes at least the housing display area where the housing display is located and the device display area corresponding to the phone mounting slot. In addition to the side frame of the protective housing providing lateral protection for the phone and the housing display, the protective ridge on the front of the protective housing also provides frontal protection for both the phone and the housing display, making them less susceptible to damage.

[0012] As a further embodiment of this invention: the outer screen panel of the shell-side display is flush with or nearly flush with the outer screen panel of the mobile phone's display. This smooth transition allows for smoother movement of the user's fingers between the shell-side display area and the device-side display area.

[0013] As a further improvement of this invention: the type of the electrical connection interface is the same as the type of the electrical connection connector. This makes data cable configuration more convenient.

[0014] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0019] Protective housing-1, mobile phone receiving slot-2, first plug-in connection port-3, electrical connection connector-4, housing end display screen-5, protective protrusion-6, battery module-7, data storage module-8, processor-9, electrical connection interface-10, mounting cavity-11. Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-2 A multi-functional expandable memory includes a protective housing 1. The front of the protective housing 1 is formed with a mobile phone receiving slot 2 for inserting a user's mobile phone. The slot on the front of the mobile phone receiving slot 2 is correspondingly formed with a mobile phone display window. The mobile phone installed in the mobile phone receiving slot 2 can display its screen through the mobile phone display window.

[0022] For example, the phone screen is located inside the phone housing and corresponds to the phone display window, or a part of the phone is located inside the phone housing while the phone screen is located outside the phone housing through the phone display window.

[0023] The protective housing 1 has a mounting cavity 11 adjacent to the mobile phone receiving slot 2. The mounting cavity 11 has a first insertion port 3 that communicates with the mobile phone receiving slot 2. The outer side of the protective housing 1 has a second insertion port that communicates with the mounting cavity 11.

[0024] The mounting cavity 11 contains a battery module 7, a data storage module 8, a processor 9, an electrical connection connector 4 that enters the mobile phone receiving slot through a plug-in port for connection with the user's mobile phone, and an electrical connection interface 10 located near and corresponding to the second plug-in port. The processor 9 makes electrical connections to the battery module 7, the data storage module 8, the electrical connection connector 4, and the electrical connection interface 10.

[0025] The data storage module 8 is used to store data. In some embodiments, the data storage module includes a ROM.

[0026] Electrical connector 4, such as a Type-C connector, Mini USB connector, or Lightning connector, can be connected to the corresponding charging interface (data-charging interface) of the user's mobile phone to enable both data transmission and charging of the mobile phone.

[0027] In some embodiments, the electrical connection interface 10 is at least capable of being used for charging, so as to charge the battery of the battery module through the charging circuit of the battery module, so that the battery can be charged and restored when the battery power is low (such as when the power is reduced after powering the mobile phone).

[0028] In some embodiments, the electrical connection interface 10 simultaneously serves the functions of data transmission and charging. Data can be connected and transmitted to external devices, such as a computer, via the data transmission-enabled electrical connection interface 10, thereby reading and modifying the data stored in the data storage module 8.

[0029] Electrical connection interface 10, such as Type-C interface, Mini USB interface, Lightning interface, etc., are interfaces that are widely used in the mobile phone industry.

[0030] Preferably, the type of electrical connector 10 is the same as the type of electrical connector 4, that is, both electrical connector 10 and electrical connector 4 are Type-C, Mini USB, or Lightning...

[0031] In this embodiment, the front of the protective housing 1 is also equipped with a housing-side display screen 5 that is electrically connected to the processor 9.

[0032] Preferably, the shell-end display screen 5 is arranged side-by-side (in sequence) with the mobile phone display window along the direction in which the electrical connection connector 4 is inserted into the user's mobile phone. In the projection of the protective shell 1 in the front-back direction (also known as the front-back direction), the shell-end display screen 5 at least partially overlaps with the mounting cavity 11. The overall area occupied is smaller.

[0033] In some embodiments, the protective housing 1 has a communication port on its front side that communicates with the mounting cavity 11, so that the housing end display screen 5 can be electrically connected to the processor 9 in the mounting cavity 11 in the form of wires.

[0034] In some embodiments, the electrical connection connector 4 is inserted into the user's mobile phone in the direction of the length of the mobile phone.

[0035] When a user holds the protective case 1: If the user does not wish to hold the phone stably by pressing their fingers against the front of the phone (the side with the display screen), and cannot hold the phone stably by simply holding the edge of the protective case, the user can choose to press some of their fingers against the display screen 5, which is an additional grip area relative to the phone, formed by the display screen 5 on the case. For example, the user can press their thumb against the display screen 5 on the case and hold the edge of the protective case 1 with their hand, thus making the grip more stable, and maintaining stability in both landscape and portrait orientations.

[0036] Especially when the installed phone is a full-screen phone or has a high screen ratio, pressing directly on the phone screen can easily trigger operation commands by mistake. The additional grip area formed by the screen 5 on the shell can solve the problems of accidental operation and significant obstruction of the phone screen caused by the traditional method of pressing on the phone screen while maintaining a stable grip.

[0037] When the protective case 1 is specifically designed for a certain size of mobile phone (such as a protective case for a specific model of mobile phone, like an iPhone 15 protective case), the outer screen of the case-side display screen 1 is flush with or nearly flush with the outer screen of the mobile phone's display screen. The transition should be as smooth as possible to allow for smoother movement of the user's fingers between the case-side display area and the device-side display area.

[0038] In this embodiment, the edge of the front of the protective housing 1 protrudes forward to form a protective ridge 6. The area surrounded by the protective ridge 6 includes at least the housing end display area where the housing end display screen 5 is located and the device end display area corresponding to the mobile phone mounting slot 2.

[0039] When the mobile phone is installed on the protective case 1, in addition to the side frame of the protective case 1 providing lateral protection for the mobile phone and the display screen 5 at the end of the case, the protective protrusion 6 on the front of the protective case 1 can also provide frontal protection for the mobile phone and the display screen 5 at the end of the case, making the mobile phone and the display screen 5 at the end of the case less prone to damage.

[0040] In some embodiments, the protective housing 1 also has an operation unit, such as a control button located on the back of the protective housing and electrically connected to the processor, or a display screen with touch function on the housing end.

[0041] In some embodiments, the operating unit can control the display screen on the shell end to light up and / or turn off.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
