Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of computers, and particularly relates to a mobile device. BACKGROUND

[0002] With the rise of digital currency and blockchain technology, smartphones have become the main terminal for digital asset management.

[0003] At present, mobile phone wallets usually rely on networked applications and are vulnerable to security threats such as malware attacks and phishing, and there is a risk of private key leakage and digital asset theft. Although some hardware wallets are highly secure, they need to be connected to a smartphone or computer to use as a separate device, which increases the operation steps and is inconvenient to use and easy to lose. SUMMARY

[0004] Embodiments of the present disclosure provide a mobile device to at least solve the problem of how to balance the security and convenience of a digital wallet.

[0005] To achieve the above-mentioned purpose, the present disclosure adopts the following technical solutions.

[0006] In a first aspect, a mobile device is provided, which includes a body and a cold wallet module. The body is provided with a receiving space, and the cold wallet module is detachably connected to the body. The cold wallet module has a first working state, a second working state and a third working state. When the cold wallet module is in the first working state, the cold wallet module is separated from the body. When the cold wallet module is in the second working state, the cold wallet module is accommodated in the receiving space, and the cold wallet module is located at a first working position. When the cold wallet module is located at the first working position, the cold wallet module is disconnected from the body. When the cold wallet module is in the third working state, the cold wallet module is accommodated in the receiving space, and the cold wallet module is located at a second working position. When the cold wallet module is located at the second working position, the cold wallet module is connected to the body.

[0007] In embodiments of the present disclosure, when the user does not use the cold wallet module for a long time, the cold wallet module can be switched to the first working state and stored separately in a safe and hidden location. When there is a need to use the cold wallet module in the short term and no transaction is required temporarily, the cold wallet module is switched to the second working state, so that the cold wallet module is completely disconnected from the Internet. When a transaction is required and used, the cold wallet module is switched to the third working state, and the cold wallet module is connected to the power supply circuit and the data transmission line of the body to normally complete the currency transaction.

[0008] In this way, the mobile device can be suitable for various use scenarios, the user needs to switch the connection state of the cold wallet module and the main body through active operation, so that the cold wallet module is activated for use, effectively enhancing the security of digital asset storage, while also taking into account the convenience of the cold wallet module.

[0018] With the rise of digital currency and blockchain technology, smartphones have become the main terminal for digital asset management.

[0019] In related technologies, digital wallets are usually of two types: hot wallets and cold wallets.

[0020] Hot wallets refer to any cryptocurrency wallet that remains connected to the Internet, usually in the form of software, such as a mobile application, browser extension, or hosted exchange wallet. Users can quickly and conveniently manage and trade cryptocurrencies through hot wallets, but since hot wallets rely on Internet environments, they are vulnerable to security threats such as malware attacks and phishing, and there is a risk of private key leakage and digital asset theft.

[0021] Cold wallets refer to cryptocurrency wallets that are not connected to the Internet, usually in the form of hardware devices or paper. The secret key of the cold wallet is stored offline and does not connect to the Internet when not needed for transactions, reducing the risk of key leakage and attacks, and providing higher security. However, as a standalone device, the cold wallet needs to be connected to a mobile device (such as a smartphone or computer, etc.) to be used, and the operation is relatively complex, and the cold wallet needs to be stored separately when not in use, which is easy to lose.

[0022] The scheme of the embodiments of the present disclosure will be described below in conjunction with the accompanying drawings.

[0023] Please refer to Figure 1 and Figure 2 , Figure 1 A structural schematic diagram of a mobile device 100 provided by the embodiments of the present disclosure, Figure 2 is Figure 1 the enlarged view of the mobile device 100 at A shown in the figure, the present disclosure provides a mobile device 100. The mobile device 100 can be a mobile phone, a tablet, a mobile computer, or a hardware device with extended functions, etc., and the present application is exemplarily described by taking the mobile device 100 as a mobile phone.

[0024] The mobile device 100 can include a body 10 and a cold wallet module 20. Figure 1 The body 10 of the mobile device 100 shown in the figure is a mobile phone body.

[0025] Please refer to Figure 3 , Figure 3This is a schematic diagram of the system architecture of a mobile device 100 provided in an embodiment of this disclosure. The main body 10 includes modules such as a main system 101, a battery 105, and a display module 106. The main system 101 may include a processor 102, an operating system 103, a communication module 104, etc. The main system 101 can be connected to the battery 105 and the display module 106. The battery 105 can supply power to the main system 101, and the display module 106 can receive display commands from the main system 101 and display information on the display module 106.

[0026] The cold wallet module 20 may include an independent motherboard 201, an independent operating system 202, and an encryption chip 203. The independent motherboard 201 is used to host the independent operating system 202 and the encryption chip 203. The independent operating system 202 can receive instructions from external devices and pass instructions for critical operations (such as private key retrieval, signature calculation, etc.) to the encryption chip 203.

[0027] The encryption chip 203 is responsible for the generation, storage, and encryption of the private key. The private key remains isolated within the chip and is not exposed to the operating system or external devices. After receiving instructions from the independent operating system 202, the encryption chip 203 performs sensitive operations such as key recognition within the chip and then feeds back the recognition results to the independent operating system 202.

[0028] When the cold wallet module 20 is separated from the main body 10, the main body 10 can perform the normal functions of the mobile device 100. When the cold wallet module 20 is powered on and the main body 10 is powered on, the cold wallet module 20 can call the necessary modules of the main body 10, such as the battery 105 and the display module, to start the operation interface of the cold wallet module 20, and can interact with the main body 10 to realize currency transactions.

[0029] Please continue to refer to Figure 1 and Figure 2 The main body 10 is provided with a storage space 11. The cold wallet module 20 is detachably connected to the main body 10, and the cold wallet module 20 has a first working state, a second working state and a third working state.

[0030] Please refer to Figure 2 and Figure 4 , Figure 4 This is a schematic diagram of a cold wallet module 20 in a first working state, as provided in an embodiment of this disclosure. In this first working state, the cold wallet module 20 is detached from the main body 10. At this time, the user can store the cold wallet module 20 separately in a secure environment, suitable for situations where the cold wallet module 20 is not needed for an extended period. Thus, the cold wallet module 20 is completely disconnected from the internet environment, reducing the risk of key leakage and asset attacks, and effectively protecting the user's property security.

[0031] In addition, the cold wallet module 20 is stored separately, so that the cold wallet module 20 is not lost due to loss or damage of the mobile device 100, and the security of the cold wallet module 20 is further improved.

[0032] It should be noted that the body 10 and the cold wallet module 20 are two independent devices, and the normal function of the body 10 is not affected after the body 10 is separated from the cold wallet module 20.

[0033] Please refer to Figure 2 and Figure 5 , Figure 5 A structure schematic diagram of a cold wallet module 20 in a second working state is provided in the embodiment of the present disclosure. In the case that the cold wallet module 20 is in the second working state, the cold wallet module 20 is accommodated in the accommodation space 11, and the cold wallet module 20 is located at the first working position. In the case that the cold wallet module 20 is located at the first working position, the cold wallet module 20 is powered off from the body 10.

[0034] The cold wallet module 20 is accommodated in the accommodation space 11, which is convenient for users to carry and store, and is suitable for situations where there is a need for currency transaction in a short period of time. However, when the cold wallet module 20 is in the second working state, the cold wallet module 20 is located at the first working position and is powered off from the body 10. At this time, the power supply line and the data transmission line of the cold wallet module 20 are in a completely cut-off state, the main system 101 of the body 10 cannot access and control the cold wallet module 20, and the cold wallet module 20 is in a completely isolated state, which can ensure the security of data.

[0035] Please refer to Figure 2 and Figure 6 , Figure 6 A structure schematic diagram of a cold wallet module 20 in a third working state is provided in the embodiment of the present disclosure. In the case that the cold wallet module 20 is in the third working state, the cold wallet module 20 is accommodated in the accommodation space 11, and the cold wallet module 20 is located at the second working position. In the case that the cold wallet module 20 is located at the second working position, the cold wallet module 20 is powered on from the body 10.

[0036] In the case that the cold wallet module 20 is in the third working state, the cold wallet module 20 is located at the second working position and is powered on from the body 10. At this time, the power supply line and the data transmission line of the cold wallet module 20 are connected with the body 10, so that the cold wallet module 20 can be activated. After the cold wallet module 20 is activated, the cold wallet module 20 can call necessary modules such as the battery 105 and the display module of the body 10, and start the operation interface of the cold wallet module 20. In this way, the user can normally perform currency transaction.

[0037] Through the above arrangement, the mobile device 100 provided by the embodiment of the present disclosure can be applied to various use scenarios. The user needs to actively operate to switch the connection state of the cold wallet module 20 and the main body 10, so that the cold wallet module 20 can be activated for use, thereby effectively enhancing the security of digital asset storage, while also taking into account the convenience of the cold wallet module 20.

[0038] In order to further ensure the security of the cold wallet module 20, in some embodiments, the data interaction between the main body 10 and the cold wallet module 20 is carried out through an isolated communication channel, and the communication data is encrypted and does not directly transmit plaintext information. In this way, the security of data transmission can be ensured during the use of the cold wallet module 20, further reducing the risk of information leakage and asset theft.

[0039] In order to realize the switching of the cold wallet module 20 between the first working state, the second working state and the third working state, please refer to Figure 2 , Figure 4~Figure 6 In some embodiments, the mobile device 100 further comprises a support base 30 arranged in the accommodation space 11. The cold wallet module 20 is detachably connected with the support base 30 to realize the connection and separation between the cold wallet module 20 and the main body 10.

[0040] Please refer to Figure 4~Figure 6 In some embodiments, the support base 30 comprises a support bottom wall 31, a first fixed side wall 32 and a second fixed side wall 33, and the first fixed side wall 32, the second fixed side wall 33 and the support bottom wall 31 form an installation groove.

[0041] When the cold wallet module 20 is in the first working state, the cold wallet module 20 is located outside the installation groove to realize the separation of the cold wallet module 20 and the main body 10.

[0042] When the cold wallet is in the second working state or the third working state, that is, when the cold wallet module 20 is in the first working position and the second working position, the cold wallet module 20 is located in the installation groove to accommodate the cold wallet module 20 in the accommodation space 11.

[0043] The support base 30 can provide a stable carrier for the cold wallet module 20. The support bottom wall 31 can provide support for the cold wallet module 20, and the first fixed side wall 32 and the second fixed side wall 33 are arranged on both sides of the cold wallet module 20 to facilitate the fixation of the cold wallet module 20 in the installation groove, thereby fixing and installing the cold wallet module 20 in the accommodation space 11 of the main body 10, reducing the risk of loss of the cold wallet module 20.

[0044] Please continue to refer to Figure 5~Figure 6In some embodiments, the support bottom wall 31 comprises a first end 311 and a second end 312 arranged oppositely, and the cold wallet module 20 can move from the first end 311 to the second end 312 when the cold wallet module 20 is connected with the support base 30.

[0045] The movement of the cold wallet module 20 from the first end 311 to the second end 312 can switch the cold wallet module 20 and the support base 30 from a separated state to a connected state, and switch the cold wallet module 20 from a power-off state to a power-on state.

[0046] The movement of the cold wallet module 20 from the second end 312 to the first end 311 can switch the cold wallet module 20 and the support base 30 from a power-on state to a power-off state, and switch the cold wallet module 20 from a connected state to a separated state.

[0047] The support bottom wall 31 is provided with a metal spring 34 near the second end 312, and the cold wallet module 20 is provided with a connection port corresponding to the metal spring 34. When the cold wallet module 20 is located at the first working position, the cold wallet module 20 is separated from the metal spring 34; when the cold wallet module 20 is located at the second working position, the connection port is connected with the metal spring 34 (the metal spring 34 in the dashed box is covered and connected by the connection port), so as to make the cold wallet module 20 and the body 10 power on. Figure 6

[0048] It should be noted that the metal spring 34 can be electrically connected with the main system 101 of the body 10, and when the connection port contacts the metal spring 34, the circuit and the communication loop between the cold wallet module 20 and the body 10 can be conducted, so as to realize the activation and use of the cold wallet module 20, and facilitate the user to carry out currency transaction.

[0049] When the cold wallet module 20 is located at the first working position, the cold wallet module 20 is separated from the metal spring 34, which can make the cold wallet module 20 and the body 10 power off, so as to cut off the electrical connection loop and the communication loop between the cold wallet module 20 and the body 10.

[0050] When the cold wallet module 20 is located at the second working position, the connection port is connected with the metal spring 34, so as to make the electrical connection loop and the communication loop between the cold wallet module 20 and the body 10 communicate, and realize the activation and use of the cold wallet module 20.

[0051] ​Since the metal spring 34 is arranged at the position close to the second end 312 of the supporting bottom wall 31, the connection of the cold wallet module 20 and the mounting groove is displaced from the first end 311 to the second end 312, thus the first displacement of the cold wallet module 20 from the first end 311 to the second end 312 can make the cold wallet module 20 enter the first working position, and the second displacement of the cold wallet module 20 from the first end 311 to the second end 312 can make the cold wallet module 20 enter the second working position. The retreat of the cold wallet module 20 from the second end 312 to the first end 311 can realize the switching from the second working position to the first working position.

[0052] In this way, when the cold wallet module 20 is not used temporarily, the user can place the cold wallet module 20 in the first working position. When a transaction is needed, the user pushes the cold wallet module 20 to be displaced from the first end 311 to the second end 312, so as to connect the connecting port and the metal spring 34, and realize the communication of the electrical connection circuit and the communication circuit between the cold wallet module 20 and the body 10.

[0053] When the transaction is completed, the user moves the cold wallet module 20 from the second end 312 to the first end 311, so as to separate the cold wallet module 20 and the metal spring 34, and realize the isolation between the cold wallet module 20 and the body 10.

[0054] In this way, the user can conveniently and quickly switch the second working state and the third working state of the cold wallet module 20, and can use conveniently while taking into account the security of the cold wallet module 20.

[0055] In other embodiments, the supporting base 30 can be provided with a rotating shaft, and the cold wallet module 20 is provided with a clamping hole, and the rotating shaft is arranged in the clamping hole to realize the rotating connection between the supporting base 30 and the cold wallet module 20. By rotating the cold wallet module around the rotating shaft, the switching between the first working position and the second working position of the cold wallet module 20 can be realized, so as to realize the switching between the second working state and the third working state of the cold wallet module 20, and can use conveniently while taking into account the security of the cold wallet module 20.

[0056] Please continue to refer to Figure 5~Figure 6 In some embodiments, the supporting base 30 includes a connecting part 35, and the cold wallet module 20 includes a first matching part 21 and a second matching part 22, the cold wallet module 20 is located in the first working position when the first matching part 21 is connected with the connecting part 35, and the cold wallet module 20 is located in the second working position when the second matching part 22 is connected with the connecting part 35.

[0057] In this way, the connecting portion 35 cooperates with the first cooperating portion 21 and the second cooperating portion 22, so that the support base 30 can limit the cold wallet module 20, prevent the cold wallet module 20 from loosening in the accommodation space 11, and prevent the cold wallet module 20 from moving between the first working position and the second working position in a non-user operation state, thereby improving the connection stability of the cold wallet module 20, reducing the possibility of the cold wallet module 20 being connected in a non-trading state, preventing key leakage or asset attacks, and further improving the security of the cold wallet module 20.

[0058] In some embodiments, the connecting portion 35 includes a first elastic protrusion arranged on the first fixed side wall 32. The first cooperating portion 21 includes a first recess, and the second cooperating portion 22 includes a second recess. The first recess and the second recess are arranged on the edge of the cold wallet module 20 facing the first fixed side wall 32, and the first recess and the second recess are arranged in a staggered manner along the arrangement direction of the first end 311 and the second end 312.

[0059] When the first recess cooperates with the first elastic protrusion, the cold wallet module 20 is located in the first working position; and when the second recess cooperates with the first elastic protrusion, the cold wallet module 20 is located in the second working position.

[0060] Since the first recess and the second recess are arranged in a staggered manner along the arrangement direction of the first end 311 and the second end 312, when the user pushes the cold wallet module 20 to move from the first end 311 to the second end 312, the cold wallet module 20 can be switched from the state of cooperating with the first recess and the first elastic protrusion to the state of cooperating with the second recess and the first elastic protrusion, thereby realizing the switching from the first working position to the second working position.

[0061] In addition, the connecting portion 35 is arranged as a first elastic protrusion. When the user pushes the cold wallet module 20, the first elastic protrusion can be elastically deformed under extrusion, so that the cold wallet module 20 can pass smoothly. When the position of the first elastic protrusion is aligned with the position of the first recess or the second recess, the first recess or the second recess can provide space for the first elastic protrusion, and the first elastic protrusion can be reset so that the first elastic protrusion can cooperate with the first recess or the second recess for limiting.

[0062] In some embodiments, the connecting portion 35 further includes a second elastic protrusion arranged on the second fixed side wall 33. The first cooperating portion 21 includes a third recess, and the second cooperating portion 22 includes a fourth recess. The third recess and the fourth recess are arranged on the edge of the cold wallet module 20 facing the second fixed side wall 33, and the third recess and the fourth recess are arranged in a staggered manner along the arrangement direction of the first end 311 and the second end 312.

[0063] The cold wallet module 20 is in the first working position when the third recess and the second elastic protrusion are matched, and the cold wallet module 20 is in the second working position when the fourth recess and the second elastic protrusion are matched.

[0064] Since the third recess and the fourth recess are arranged at intervals along the arrangement direction of the first end 311 and the second end 312, when the user pushes the cold wallet module 20 to displace from the first end 311 toward the second end 312, the cold wallet module 20 can be switched from the state that the third recess and the second elastic protrusion are matched to the state that the fourth recess and the second elastic protrusion are matched, thereby realizing the switching from the first working position to the second working position.

[0065] Similarly, the connecting part 35 is arranged as a second elastic protrusion, which can elastically deform under extrusion when the user pushes the cold wallet module 20, so that the cold wallet module 20 can pass smoothly. When the position of the second elastic protrusion is aligned with the position of the third recess or the fourth recess, the third recess or the fourth recess can leave space for the second elastic protrusion, and the second elastic protrusion resets so that the second elastic protrusion can be limited by matching the third recess or the fourth recess.

[0066] In order to enable the connecting part 35 to elastically deform, in some embodiments, the connecting part 35 can be arranged as an elastic material. For example, the connecting part 35 can be arranged as rubber, nylon, plastic or elastic metal.

[0067] In some embodiments, the connecting part 35 can be integrally formed with the first fixed side wall 32 and / or the second fixed side wall 33. In this way, the first fixed side wall 32 and / or the second fixed side wall 33 can be arranged as a metal strip, and the connecting part 35 is arranged as a metal strip protrusion. When the connecting part 35 is extruded, the metal strip protrusion can deform, and when the extrusion force is removed, the metal strip protrusion returns to its original shape.

[0068] In other embodiments, the connecting part 35 can include a fifth recess, the first matching part 21 can include a third elastic protrusion, and the second matching part 22 can include a fourth elastic protrusion. The fifth recess can be matched with the third elastic protrusion or the fourth elastic protrusion, respectively, so that the connecting part 35 can be limited by matching the first matching part 21 or the second matching part 22.

[0069] It can be understood that when the connecting part 35 is arranged as a recess, the connecting part 35 can also be an elastic structure, and when the first matching part 21 and the second matching part 22 are arranged as protrusions, the first matching part 21 and the second matching part 22 can also be non-elastic structures.

[0070] In some embodiments, the support base 30 can include a first limiting portion and a second limiting portion, the first limiting portion and the second limiting portion being arranged along the arrangement direction of the first end 311 and the second end 312; the cold wallet module 20 is provided with a third limiting portion on the side facing the first limiting portion and the second limiting portion, the third limiting portion being capable of cooperating with the first limiting portion and the second limiting portion. When the third limiting portion cooperates with the first limiting portion, the cold wallet module 20 is located at the first working position; when the third limiting portion cooperates with the second limiting portion, the cold wallet module 20 is located at the second working position.

[0071] In this way, when the user pushes the cold wallet module 20 to displace from the first end 311 to the second end 312, the cold wallet module 20 can be switched from the state of the third limiting portion cooperating with the first limiting portion to the state of the third limiting portion cooperating with the second limiting portion, thereby realizing the switching from the first working position to the second working position. In some embodiments, the first limiting portion and the second limiting portion can be arranged as one of a protrusion or a recess matched with each other, and the third limiting portion can be arranged as the other one of a protrusion or a recess matched with each other, so as to realize the cooperation of the third limiting portion with the first limiting portion or the cooperation of the third limiting portion with the second limiting portion.

[0072] In order to realize the switching of the cold wallet module 20 from the second working position to the first working position, in some embodiments, the mobile device 100 further includes a switching mechanism 40 arranged in the accommodation space 11, used for switching the cold wallet module 20 from the third working state to the second working state or the first working state, and switching the cold wallet module 20 from the second working state to the first working state.

[0073] In this way, the user can conveniently separate the cold wallet module 20 from the body 10 by controlling the switching mechanism 40, thereby facilitating the security of the cold wallet module 20.

[0074] Please refer to Figure 2 and Figure 7 , Figure 7 A partial structure schematic diagram of a mobile device 100 provided by the embodiments of the present disclosure, in some embodiments, the accommodation space 11 includes a first opening 12 and a second opening 13, the arrangement direction of the first opening 12 and the second opening 13 is consistent with the arrangement direction of the first fixed side wall 32 and the second fixed side wall 33, and the first opening 12 is used for enabling the cold wallet module 20 to enter the accommodation space 11.

[0075] The switching mechanism 40 comprises a rotating shaft 41 and a rotating rod 42. The rotating shaft 41 is arranged at a side of the accommodating space 11 away from the first opening 12 and the second opening 13. The rotating rod 42 is rotationally connected to the rotating shaft 41. One end of the rotating rod 42 is directed towards the first opening 12, and the other end of the rotating rod 42 is directed towards the second opening 13. The one end of the rotating rod 42 is defined as a third end 421, and the other end of the rotating rod 42 is defined as a fourth end 422.

[0076] The first opening 12 is used for the cold wallet module 20 to enter the accommodating space 11. A user places the cold wallet module 20 at the first opening 12 and pushes the cold wallet module 20 into the accommodating space 11, so that the cold wallet module 20 is switched from a state of being separated from the body 10 to the first working position. When the cold wallet module 20 is in the first working position, the user pushes the cold wallet module 20 again, so that the cold wallet module 20 is switched from the first working position to the second working position, facilitating the cold wallet module 20 to be powered with the body 10, and realizing that the power-on loop and the communication loop are conducted.

[0077] When the cold wallet module 20 is in the second working position, the cold wallet module 20 is completely placed in the accommodating space 11.

[0078] However, if the first opening 12 is larger than the cold wallet module 20, dust and moisture are likely to enter the accommodating space 11 through the first opening 12, affecting the reliability and safety of the use of the cold wallet module 20. Therefore, the size of the first opening 12 needs to be matched with the size of the cold wallet module 20 to protect the cold wallet module 20 and the body 10.

[0079] Since the space of the first opening 12 is small, it is relatively simple for a user to apply a pushing force to the cold wallet module 20 when the cold wallet module 20 is in the first opening 12, but it is relatively difficult for the user to apply a pulling force to the cold wallet module 20 to take the cold wallet module 20 out of the first opening 12. That is, it is difficult for the user to switch the cold wallet module 20 from the second working position to the first working position or separate the cold wallet module 20 from the body 10.

[0080] At this time, the rotating shaft 41 in the switching mechanism 40 is arranged at a side of the accommodating space 11 away from the first opening 12 and the second opening 13, and the rotating rod 42 is rotationally connected to the rotating shaft 41. A user can apply a pushing force to the cold wallet module 20 through the rotating rod 42, with the pushing force being directed from the second end 312 towards the first end 311. In this way, it is easier for the user to take the cold wallet module 20 out.

[0081] In addition, since the space of the first opening 12 is small, it is difficult for a user to control the rotating rod 42 to apply a pushing force to the cold wallet module 20 from the first opening 12.

[0082] Therefore, the second opening 13 is arranged on the body 10 and communicates with the accommodating space 11, the arrangement direction of the second opening 13 and the first opening 12 is consistent with the arrangement direction of the first fixed side wall 32 and the second fixed side wall 33, and the user can push the rotating rod 42 to rotate through the second opening 13, so as to apply the pushing force from the second end 312 to the first end 311 to the cold wallet module 20.

[0083] The third end 421 of the rotating rod 42 is towards the first opening 12, and the fourth end 422 of the rotating rod 42 is towards the second opening 13. In this way, when the cold wallet module 20 is in the first working position or the second working position, the third end 421 of the rotating rod 42 is towards the cold wallet module 20, and the fourth end 422 is towards the user.

[0084] The user applies the pushing force from the first end 311 to the second end 312 to the fourth end 422, and the rotating rod 42 can rotate around the rotating shaft 41, so as to apply the pushing force from the second end 312 to the first end 311 to the third end 421 of the cold wallet module 20, so as to switch the cold wallet module 20 from the second working position to the first working position, or separate the cold wallet module 20 from the body 10.

[0085] In this way, the user can conveniently and quickly switch the cold wallet module 20 from the third working state to the second working state or the first working state, so as to disconnect the cold wallet module 20 from the body 10 when the cold wallet module 20 is not used for transaction, so as to be away from the Internet environment, prevent the secret key from being leaked or attacked by hackers, and improve the security of the cold wallet module 20.

[0086] In some embodiments, the switching mechanism 40 further comprises an extension rod 43, the extension rod 43 is connected to the other end of the rotating rod 42, and the extension rod 43 extends towards the second opening 13.

[0087] The extension rod 43 is used for the user to apply the pushing force from the first end 311 to the second end 312 to the fourth end 422, the extension rod 43 extends from the fourth end 422 of the rotating rod 42 towards the second opening 13, so that the extension rod 43 can reduce the distance from the fourth end 422 of the rotating rod 42 to the first opening 12, and facilitate the user to push the rotating rod 42 to rotate.

[0088] In some examples, the extension rod 43 and the rotating rod 42 can be connected by a pin shaft or a mechanical connection such as clamping, and the extension rod 43 and the rotating rod 42 can also be arranged as an integrated structure.

[0089] In some embodiments, one end of the extension rod 43 towards the second opening 13 can be provided with a bending part, through which the size of the extension rod 43 in the orthographic projection of the plane where the second opening 13 is located can be increased, so as to improve the accuracy of the user pushing the extension rod 43.

[0090] In some other embodiments, the switching mechanism 40 can include a slide rail arranged at the second end 312 of the support base 30, and a slide block, the slide rail extending in the same direction as the arrangement direction of the first end 311 and the second end 312, and the slide block being slidably connected with the slide rail.

[0091] The user controls the slide block to slide from the second end 312 to the first end 311, which can push the cold wallet module 20 to translate along the second end 312 to the first end 311, so as to realize the switching of the cold wallet module 20 from the second working position to the first working position.

[0092] In some other embodiments, the switching mechanism 40 can further include a protrusion arranged at one end of the cold wallet module 20, when the cold wallet module 20 is located at the second working position, the protrusion can protrude from the surface of the cold wallet module 20 and be located outside the first opening. The user can pull the protrusion to switch the cold wallet module 20 from the second working position to the first working position.

[0093] In some embodiments, the mobile device 100 further includes a dust cover 50, which is connected with the first opening 12 in a matching manner to close the first opening 12. In this way, when the user does not need to displace the cold wallet module 20, the dust cover 50 can be covered on the first opening 12 to close the first opening 12, so as to prevent dust or moisture from entering the inside of the cold wallet module 20 or the body 10, and causing damage to the mobile device 100.

[0094] In a possible structural design, the dust cover 50 is clamped with the body 10 to close the first opening 12. In another possible structural design, the dust cover 50 is interference-fitted with the first opening 12 or the dust cover 50 is screwed with the body 10.

[0095] Please continue to refer to Figure 7 The embodiments of the present disclosure further provide a booster 60, which includes an end head that can enter the containing space 11 through the second opening 13 and can push the rotating rod 42 to rotate.

[0096] In this way, the user can use the booster 60 to switch the cold wallet module 20 from the third working state to the second working state or the first working state, which is more convenient and simple to operate.

[0097] In some embodiments, the number of ends of the assisting member 60 can be set to two, i.e., the first end 61 and the second end 62, and the length of the first end 61 is greater than that of the second end 62. In this way, when the user needs to switch the cold wallet module 20 from the third working state to the second working state, i.e., the cold wallet module 20 is located in the accommodation space 11 but is powered off from the body 10, the shorter second end 62 can be used to push the rotating rod 42. When the user needs to take the cold wallet module 20 out of the accommodation space 11, the longer first end 61 can be used.

[0098] In this way, the position switching of the cold wallet module 20 can be accurately realized, and the cold wallet module 20 is prevented from being pushed too much to be unstable or shaken and taken out of the accommodation space 11 when the user wants to switch the cold wallet module 20 from the third working state to the second working state.

[0099] Please refer to Figure 8 , Figure 8 A flowchart of a use method of the cold wallet module 20 is provided for the embodiments of the present disclosure, and the embodiments of the present disclosure further provide a use method of the cold wallet module 20, which comprises the following steps: S1, switching the cold wallet module 20 to the third working state.

[0100] At this time, the power supply line and the data transmission line between the cold wallet module 20 and the body 10 are in communication, the cold wallet module 20 is powered on, and the user can activate and use the cold wallet module 20.

[0101] After the cold wallet module 20 is powered on in step S1, the cold wallet module 20 can automatically call the necessary modules such as the battery 105 and the display module of the body 10 to start the cold wallet operation interface.

[0102] In some embodiments, the cold wallet module 20 comprises a multiple authentication component, and multiple verification methods such as a personal identification number (PIN code) or a fingerprint are required when logging in to the cold wallet system.

[0103] After the cold wallet module 20 is powered on, a prompt of “input PIN code” can be popped up on the display module.

[0104] The use method of the cold wallet module 20 further comprises: S2, inputting the PIN code.

[0105] When the user uses the cold wallet module 20 for the first time, the cold wallet module 20 needs to be activated, and the activation of the cold wallet module 20 requires the setting of a personal identification number (PIN code) of the cold wallet module 20, that is, after the cold wallet module 20 is powered on in step S1, the PIN code is input as a starting PIN code in step S2, and after the setting is completed, the PIN code is stored in the cold wallet module 20. In the future, the user needs to input the PIN code and verify the identity before entering the system each time the cold wallet module 20 is started.

[0106] When the user uses the cold wallet module 20 for the first time, the cold wallet module 20 needs to be activated, and the activation of the cold wallet module 20 requires the setting of a personal identification number (PIN code) of the cold wallet module 20, that is, after the cold wallet module 20 is powered on in step S1, the PIN code is input as a starting PIN code in step S2, and after the setting is completed, the PIN code is stored in the cold wallet module 20. In the future, the user needs to input the PIN code and verify the identity before entering the system each time the cold wallet module 20 is started.

[0107] If the information is consistent, the cold wallet module 20 is successfully logged in, and the user can perform currency transactions; if the information is inconsistent, the prompt "input PIN code" is popped up again on the display module, and the user needs to perform step S2 again to compare the information to log in the system of the cold wallet module 20.

[0108] In this way, the security of the cold wallet module 20 can be further ensured.
