[0046] In an example, referring to Figures 3 to 6As shown, an expansion device 40 is in the form of a mobile phone shell, which can be sleeved on the mobile phone to physically protect the mobile phone. The expansion device 40 is accommodated in the accommodation space 412 of the mobile phone. The bottom wall of the accommodation space 412 is provided with an assembly space 411. The expansion card 10 is detachably arranged in the assembly space 411. The expansion card 10 can include: a substrate 11 and an interface assembly 12. The substrate 11 is provided with a storage module 111. The interface assembly 12 is connected with the substrate 11 and at least includes: a first interface 121 and a second interface 122 electrically connected with the first interface 121. The first interface 121 is electrically connected with the storage module 111 and exposed from a first side of the substrate 11, and can be electrically connected with the mobile phone in the accommodation space 412. The second interface 122 is electrically connected with the storage module 111 and exposed from a second side of the substrate 11. The first interface 121 is used for electrically connecting the first device 20 (such as the mobile phone in the accommodation space 412). The second interface 122 is used for electrically connecting the second device 30 (such as a notebook computer). The first interface 121 and the second interface 122 can be in a use mode at the same time. The expansion card 10 can have the following use modes:

[0047] Mode one: the first interface 121 is electrically connected with the mobile phone, so that the mobile phone and the storage module 111 are electrically connected through the first interface 121, to enable the transmission of data between the mobile phone and the storage module 111. For example, the mobile phone can issue an instruction through an APP on the mobile phone to retrieve data of the storage module 111 through the first interface 121, so as to realize the expansion of the storage space of the mobile phone.

[0048] Mode two: the first interface 121 is electrically connected with the mobile phone, so that the mobile phone and the storage module 111 are electrically connected through the first interface 121, to enable the transmission of data between the mobile phone and the storage module 111. For example, the mobile phone can issue an instruction through an APP on the mobile phone to retrieve data of the storage module 111 through the first interface 121, so as to realize the expansion of the storage space of the mobile phone. At the same time, through the electrical connection between the second interface 122 and the first interface 121, the electrical connection between the mobile phone connected with the first interface 121 and the notebook computer connected with the second interface 122 can be realized, so that the notebook computer can charge the mobile phone and the data of the notebook computer and the mobile phone can be transmitted to each other. For example, the notebook computer can issue an instruction through an APP on the notebook computer to retrieve data of the mobile phone through the second interface 122 and the first interface 121. Moreover, the notebook computer can be electrically connected with the storage module 111 through the second interface 122, to realize the mutual transmission of data between the notebook computer and the storage module 111.

[0049] In the embodiment, the capacity expansion card 10 can include a substrate 11 and an interface assembly 12, the substrate 11 is provided with a storage module 111, and a first interface 121 of the interface assembly 12 is electrically connected with the storage module 111 and can be connected with the first device 20 to enable data transmission between the first device 20 and the storage module 111, so that the storage space of the first device 20 can be expanded. This way, the first device 20 does not need to be replaced with a large-capacity memory card to reduce the risk of damage, affect the warranty, and other problems that may occur when disassembling the device. In addition, the first device 20 does not need to be replaced with another first device 20 with a large-capacity storage space to avoid the problem of high purchase cost. At the same time, cloud storage is not required to avoid the risk of privacy leakage. In addition, the capacity expansion card 10 is also provided with a second interface 122 electrically connected with the first interface 121. While the first device 20 and the storage module 111 exchange data, the second interface 122 can be connected with the second device 30, a power adapter, and the like. The second device 30, the power adapter, and the like provide electrical energy through the second interface 122 and the first interface 121, which is transmitted to the first device 20 through the first interface 121 to charge the first device 20. Data transmission between the second device 30 and the first device 20 can also be achieved through the second interface 122 and the first interface 121. In the case where the second device 30 connected to the second interface 122 is a notebook computer or the like, the second device 30 and the storage module 111 can also exchange data through the second interface 122.

[0050] In some embodiments, as shown in Figure 5 、 Figure 6 and Figure 10 , the first device 20 is a first electronic device; and the second device 30 is a second electronic device or a power adapter device. The first electronic device can be a mobile phone, a music player, a solid state disk, etc. The second electronic device can be a notebook computer, etc. The first device 20 and the second device 30 are different, so that data transmission can be performed between the first device 20 and the storage module 111 of the capacity expansion card 10. The second device 30 can provide electrical energy to the first device 20 through the capacity expansion card 10 to charge the first device 20. Data transmission between the first device 20 and the second device 30 can also be achieved through the capacity expansion card 10. Data transmission between the second device 30 and the storage module 111 of the capacity expansion card 10 can also be achieved through the capacity expansion card 10.

[0051] In some embodiments, the first interface 121 includes a first connection surface to be in contact with a second connection surface of the first device 20; and the second interface 122 includes a female connector to be connected with a male connector of the second device 30.

[0052] The first connecting surface of the first interface 121 and the second connecting surface of the first device 20 are in contact with each other to facilitate the electrical connection between the first interface 121 and the first device 20. In one example, the first device 20 has some exposed electrical components on its outer surface to form the second connecting surface, or a connecting member is electrically connected to the first device 20 and partially fixed on the outer side of the first device 20 to form the second connecting surface. In one example, the first protective shell that can be sleeved on the outer side of the mobile phone to physically protect the mobile phone has a containing space 412 to accommodate the mobile phone. The inner bottom wall of the containing space 412 is recessed with an assembly space 411 to accommodate the expansion card 10. In the case that the expansion card 10 is assembled in the assembly space 411 and the mobile phone is assembled in the containing space 412, the first connecting surface and the second connecting surface correspond to two surfaces of the expansion card 10 and the mobile phone respectively and are in contact with each other to reduce the risk of short circuit, discharge, etc. of the first device 20 in the case that the first device 20 is not assembled in the containing space 412.

[0053] The plug-in female port of the second interface 122 can be in the form of a TYPE-A female port, a TYPE-C female port, etc. It can be set according to the form of the male port of the second device 30, or the second interface 122 can be detachably set on the substrate 11, so that different forms of female ports can be connected to the substrate 11 by replacement to meet the design of different types of male ports of different second devices 30.

[0054] In some embodiments, as shown in Figure 2 , Figure 6 and Figure 10 The expansion card 10 can further include a function module 13 and a processing module 14. The function module 13 is arranged on the substrate 11 and includes at least one of an audio input module and an audio output module. The processing module 14 is arranged on the substrate 11, electrically connected to the function module 13, and electrically connected to the storage module 111, the first interface 121, and the second interface 122 respectively.

[0055] In other words, the expansion card 10 can be further provided with a function module 13 and a processing module 14 in the case of being provided with the storage module 111. The function module 13 can at least include an audio input module (such as a recording function, etc.) and / or an audio output module (such as a voice playing function), and can further include a display module capable of displaying storage information of the storage module 111, processing information of the processing module 14, etc. The processing module 14 can process the content input and / or output by the function module 13, and can also process the content stored by the storage module 111, the content input / output by the first interface 121, and the content input / output by the second interface 122, and can be sent to at least one of the storage module 111, the first interface 121, the second interface 122, and the function module 13, so as to further expand the function of the expansion card 10. The processing module 14 can perform voice changing, translation, speed changing, time length cutting, etc. on the voice recorded by the audio input module, and can also perform voice changing, translation, speed changing, time length cutting, etc. on the voice to be output by the audio output module.

[0056] In some embodiments, as shown in Figure 2 、 Figure 6 and Figure 10 , the expansion card 10 can further include a transmission module 15, and the storage module 111, the first interface 121, the second interface 122, and the processing module 14 are all electrically connected with the transmission module 15. The transmission speed of the transmission module 15 is greater than 10 Gbps.

[0057] Here, the transmission speed of the transmission module 15 is greater than 10 Gbps, which can achieve the purpose of rapid transmission and provide sufficient bandwidth, such as rapid transmission of data between the first device 20 and the storage module 111, rapid transmission of data between the first device 20 and the second device 30, rapid transmission of data between the processing module 14 and the first interface 121 and the second interface 122, rapid transmission of data between the processing module 14 and the function module 13, etc.

[0058] The second aspect

[0059] The present disclosure provides an expansion device 40, as shown in Figures 3 to 10As shown, the expansion device 40 can include a main body 41 and an expansion card 10. The main body 41 is provided with an assembly space 411. The expansion card 10 is detachably arranged in the assembly space 411, and can be switched from the assembly space 411 of one main body 41 to the assembly space 411 of another main body 41. The expansion card 10 can include a substrate 11 and an interface assembly 12. The substrate 11 is provided with a storage module 111. The interface assembly 12 is connected with the substrate 11 and includes at least a first interface 121 and a second interface 122 electrically connected with the first interface 121. The first interface 121 is electrically connected with the storage module 111 and exposed from a first side of the substrate 11. The second interface 122 is electrically connected with the storage module 111 and exposed from a second side of the substrate 11. The first interface 121 is used for electrically connecting the first device 20. The second interface 122 is used for electrically connecting the second device 30. The first interface 121 and the second interface 122 can be in the use mode at the same time.

[0060] The main body 41 can be a first protective shell sleeved outside the first device 20, or a second protective shell in the form of a box body, or other structures. The size of the assembly space 411 arranged on the main body 41 can be consistent with the size of the expansion card 10, so that the expansion card 10 is fixed relative to the main body 41 when the expansion card 10 is assembled in the assembly space 411, thereby reducing the probability of collision damage caused by shaking of the expansion card 10 relative to the main body 41. The expansion card 10 can be assembled in the assembly space 411 by adsorption, screw fixation or other methods, so that the expansion card 10 can be detached, thereby facilitating cleaning, maintenance, replacement and other operations of the expansion card 10.

[0061] In addition, the main body 41 can be further provided with a power module electrically connected with the first interface 121, so that the first device 20 can be charged by the power module when the first interface 121 is electrically connected with the first device 20.

[0062] In the embodiment, the size of the expansion device 40 can meet the requirement of convenient carrying, which is very convenient for both business trips and daily use.

The assembly space 411 is arranged on the inner bottom wall of the containing space 412. The main body 41 is provided with a through hole 4121 corresponding to the second interface 122.

[0064] In other words, the expansion card 10 can be first installed in the assembly space 411 through the receiving space 412, and then the first device 20 can be installed in the receiving space 412, covering the expansion card 10. In this way, the first device 20 can not only be physically protected by the main body 41, but also cover the expansion card 10 to cooperate with the main body 41 to physically protect the expansion card 10. Here, when the first interface 121 is the first connecting surface and the first device 20 is provided with a second connecting surface, the first connecting surface can be provided on the surface of the expansion card 10 covered by the first device 20, and the first device 20 is provided with a second connecting surface at the position corresponding to the first connecting surface, so that when the first device 20 is installed in the receiving space, the first connecting surface and the second connecting surface can be relative to each other to achieve contact connection. The main body 41 is provided with a through hole 4121 at the position corresponding to the second interface 122, so that the second device 30, power adapter and other devices can be connected to the second interface 122 through the through hole 4121.

[0065] In some embodiments, see Figure 3 and Figure 4 As shown, the main body 41 may further include: a first cover 413, which is capable of closing the opening of the assembly space 411 and opening the opening of the assembly space 411; when the first cover 413 closes the opening of the assembly space 411, the first cover 413 is flush with the inner bottom wall of the receiving space 412.

[0066] The first cover 413 and the main body 41 can be connected by means of rotational connection, snap-fit ​​connection, screw connection, etc. In the case of rotational connection, the first cover 413 can rotate forward or backward relative to the main body 41 to correspondingly close or open the opening of the assembly space 411; in the case of snap-fit ​​connection, the first cover 413 can be snapped on or off to correspondingly close or open the opening of the assembly space 411; in the case of screw connection, the first cover 413 can be screwed on or off to correspondingly close or open the opening of the assembly space 411. In this way, the opening of the assembly space 411 can be closed by the first cover 413 to limit the expansion card 10 within the assembly space 411, and it can be opened to remove the expansion card 10 for replacement, cleaning, and other operations.

[0067] When the first cover 413 closes the opening of the assembly space 411, the first cover 413 is flush with the inner bottom wall of the receiving space 412, so that when the first device 20 is assembled in the receiving space 412, the first device 20 abuts against the inner bottom wall of the receiving space 412 and against the first cover 413, so that the structure between the first device 20 and the expansion device 40 is more compact, fits better, and has fewer gaps.

[0068] In some embodiments, see Figures 7 to 10As shown, the main body 41 is a second protective shell, and the outer surface of the main body 41 is recessed to form an assembly space 411. The main body 41 also includes: a second cover 414, which can close the opening of the assembly space 411 and open the assembly space 411; at least a portion of the first device 20 is disposed inside the main body 41 and has a storage device; and the second interface 122 is exposed outside the expansion device 40.

[0069] After the second cover 414 opens the assembly space 411, the expansion card 10 can be installed in the assembly space 411. Then, the second cover 414 closes the opening of the assembly space 411, so that the expansion card 10 can be physically protected by the cooperation of the second cover 414 and the main body 41. The expansion card 10 in the assembly space 411 can be disassembled for replacement, maintenance, or other operations by opening the second cover 414 again. The second cover 414 and the main body 41 can be connected by a rotating connection, a snap-fit ​​connection, a screw connection, or other movable connection methods. The movable connection method and corresponding effect between the first cover 413 and the main body 41 can be referred to, and will not be described in detail here.

[0070] like Figure 10 As shown, the first device 20 can be a solid-state drive (SSD) so that the expansion device 40 also has the functions of a solid-state drive. The Type-C connector of the solid-state drive can be exposed from the outside of the expansion device 40 so that the second device 30 can be connected to the solid-state drive through the Type-C connector of the solid-state drive. The solid-state drive can be connected to the first interface 121. In this way, data transmission between the second device 30 and the storage module 111 can be realized through the solid-state drive and the first interface 121.

[0071] The second interface 122 is exposed to the outside of the expansion device 40 so that the main body 41 and the second cover 414 cannot interfere with the connection between the second interface 122 and the second device 30. The exposure method can be as follows: Figures 7 to 9 The opening 4141 shown is illustrated.

[0072] In some embodiments, see Figure 7 As shown, the outer surface of the main body 41 is also provided with an identification area 415, which is electrically connected to the storage module 111. The identification area 415 is used for biometric identification.

[0073] The biological feature can include, but is not limited to, a fingerprint, an iris, a face, etc. When the biological feature is opposite to the identification area 415, if the biological feature is consistent with the biological feature information stored in the storage module 111 in advance, the expansion device 40 can be unlocked, so that the expansion device 40 can work. On the contrary, if the biological feature is inconsistent with the biological feature stored in the storage module 111 in advance, the expansion device 40 is still in a locked state, so that the expansion device 40 cannot work.
