The multiple support bars support the PCB board so that an air chamber is formed between the inner wall of the memory expansion chamber and the PCB board.

[0013] As a further solution of the present invention, the air chamber starts from one side of the PCB board and passes through the board surface of the corresponding support strip on the PCB board, thereby reaching the opposite side of the PCB board.

[0014] Compared with the existing technology, the beneficial effect of this technical solution is that when expanding the capacity, the storage module in the memory expansion chamber and the battery module in the power expansion chamber can be insulated from each other through the insulation chamber, so that the heat generated by the battery module during use is not easy to affect the storage module, thereby avoiding affecting the performance of the storage module.

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 1-3 The expandable mobile storage device for mobile devices comprises a first shell 1 and a second shell 2 arranged on the first shell 1. The first shell 1 is provided with a mounting slot 3 for accommodating the mobile device.

[0024] In some embodiments, the mobile device used may be a mobile phone. Accordingly, the mounting slot 3 is a mobile phone mounting slot, and the first housing 1 is mounted on, for example, the frame and back of the mobile phone through the mobile phone mounting slot.

[0025] In this embodiment, the first housing 1 and the second housing 2 enclose an electrical connection chamber 4 communicating with the mounting groove 3 , and an expansion chamber communicating with the electrical connection chamber 4 .

[0026] A partition assembly 5 is provided in the expansion chamber, which divides the expansion chamber into a memory expansion chamber 6, a power expansion chamber 7, and an insulation chamber 8 located between the memory expansion chamber 6 and the power expansion chamber 7 to separate the memory expansion chamber 6 from the power expansion chamber 7.

[0027] The electrical connection chamber 4 houses a control unit 9 and a device connector 10 extending from the connection between the electrical connection chamber 4 and the mounting slot 3. The memory expansion chamber 6 houses a storage module 11 electrically connected to the control unit 9, while the power expansion chamber 7 houses a battery module 12 electrically connected to the control unit 9.

[0028] The control unit 9 can be connected to the mobile device by plugging the device plug connector 10 into the interface corresponding to the mobile device, thereby providing memory expansion for the mobile device through the storage module 11 and power expansion for the mobile device through the battery module 12. The power expansion is, for example, to power the mobile device through the battery module to improve the battery life.

[0029] When expanding the capacity, the insulation chamber 8 can be used to insulate the storage module 11 in the memory expansion chamber 6 and the battery module 12 in the power expansion chamber 7 from each other, so that the heat generated by the battery module 12 during use is not easy to affect the storage module 11, thereby avoiding affecting the performance of the storage module 11.

[0030] like Figure 1 、 3 As shown, in some embodiments, the mounting slot 3 is open upward, the back of the first shell 1 corresponds to the lower part, and the memory expansion chamber 6, power expansion chamber 7, and thermal insulation chamber 8 formed by the second shell 2, the first shell 1, and the partition assembly 5 are all located below the first shell 1.

[0031] like Figure 3 As shown, the heat-insulating chamber 8 is a chamber with a receiving space, and a corresponding heat-insulating design can be performed inside it to achieve a better heat-insulating effect, such as filling it with air, adding a heat-insulating baffle, etc.

[0032] In this embodiment, the storage module 11 includes a PCB board 111 with chips soldered thereon. The chips include, for example, a flash memory chip, a main control chip, a buffer chip, and the like.

[0033] The memory expansion chamber 6 , the heat insulation chamber 8 and the power expansion chamber 7 are arranged in sequence along a direction parallel to the welding board surface of the PCB board 111 .

[0034] like Figure 2 、 3 As shown, the soldering surface of the PCB is horizontally arranged, and the memory expansion chamber, the heat insulation chamber, and the power expansion chamber are arranged in sequence from front to back. This allows the height of the heat insulation chamber to be set as small as possible.

[0035] Preferably, the battery module 12 includes at least one plate-shaped battery 121 , and the flat surface of the plate-shaped battery 121 is parallel to the soldering surface of the PCB board 111 .

[0036] In some embodiments, a plurality of support bars 13 corresponding to the surface of the PCB board 111 are formed in the memory expansion chamber 6 .

[0037] Preferably, the support bar 13 is an elastic support bar.

[0038] More preferably, the plurality of support bars 13 have the same length and are spaced apart in a direction parallel to the soldering surface of the PCB 111. The plurality of support bars 13 support the PCB 111, thereby forming an air chamber 14 between the inner wall of the memory expansion chamber 6 and the PCB 111. The air chamber 14 originates from one side of the PCB 111 and passes from the surface of the PCB 111 corresponding to the support bar 13, thereby reaching the opposite side of the PCB 111.

[0039] like Figure 3 As shown, the air chamber 14 starts from the left side of the PCB board 111 and passes through the bottom surface of the PCB board 111 corresponding to the support bar 13, thereby reaching the right side of the PCB board 111.

[0040] When the shell is hit, the design of the elastic support strip and the air chamber makes the storage module 11 in the memory expansion chamber 6 less susceptible to damage, thereby improving safety.

[0041] In some embodiments, the electrical connection chamber 4 is connected to at least the memory expansion chamber 6 and the power expansion chamber 7, so that the storage module 11 and the control unit 9 can be electrically connected through a wired connection, so that the battery module 12 and the control unit 9 can be electrically connected through a wired connection.

[0042] 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.
