[0049] In order to make the objectives, technical solutions and advantages of this application clearer, the implementation methods of this application will be further described in detail below with reference to the accompanying drawings.

[0050] This application embodiment provides a connection device, please refer to Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a connection device provided in an embodiment of the present application. The connection device 000 may include: a supporting shell 100 .

[0051] The supporting shell 100 in the connecting device 000 may include: a first slot body K1 and a second slot body K2 which are separately arranged. Figure 2 As shown, Figure 2 This is a side view of a connection device provided by an embodiment of the present application, which is connected to a functional device and a terminal device. The first slot K1 of the supporting shell 100 in the connection device 000 can be used to accommodate the functional device 010, and the second slot K2 of the supporting shell 100 in the connection device 000 can be used to accommodate the terminal device 020. After the functional device 010 is positioned within the first slot K1 of the supporting shell 100 and the terminal device 020 is positioned within the second slot K2 of the supporting shell 100, the functional device 010 can communicate with the terminal device 020.

[0052] It should be noted that the functional device 010 can be a portable printing device (such as a mini printer or pocket printer), an audio playback device, a portable projection device (such as a pocket projector), a portable data storage device (such as a mobile hard drive box, a portable cloud storage device), a wireless routing device (such as a portable WiFi, a mini router), or an energy storage device (such as a power bank). The terminal device 020 can be a non-foldable device or a foldable device, etc. This embodiment of the application does not specifically limit this.

[0053] In one possible scenario, if the functional device 010 is a portable printing device, after the portable printing device is located within the first slot K1 of the supporting housing 100 and the terminal device 020 is located within the second slot K2 of the supporting housing 100, the portable printing device and the terminal device 020 can establish a communication connection. In this way, after receiving the information to be printed sent by the terminal device 020, the portable printing device can print based on the information to be printed.

[0054] In another possible scenario, if the functional device 010 is an audio playback device, after the audio playback device is located in the first slot K1 of the supporting shell 100 and the terminal device 020 is located in the second slot K2 of the supporting shell 100, the audio playback device and the terminal device 020 can be communicatively connected. In this way, after receiving the to-be-played information sent by the terminal device 020, the audio playback device can play the audio based on the to-be-played information.

[0055] In another possible scenario, where functional device 010 is an energy storage device, after the energy storage device is located within the first slot K1 of the supporting shell 100 and the terminal device 020 is located within the second slot K2 of the supporting shell 100, the energy storage device and the terminal device 020 can establish a communication connection. In this way, after receiving the charging request information sent by the terminal device 020, the energy storage device can charge the terminal device 020 based on the charging request information.

[0056] In this application, the first slot K1 of the supporting case 100 can be used to accommodate the functional device 010, and the second slot K2 of the supporting case 100 can be used to accommodate the terminal device 020. Once the functional device 010 is located within the first slot K1 of the supporting case 100 and the terminal device 020 is located within the second slot K2 of the supporting case 100, the functional device 010 can establish a communication connection with the terminal device 020. Furthermore, once the functional device 010 is located within the first slot K1 of the supporting case 100, the functional device 010 and the connection device 000 are integrated, making them more convenient for users to carry.

[0057] In summary, the present application provides a connection device comprising a supporting case. A first slot in the supporting case can accommodate a functional device, and a second slot in the supporting case can accommodate a terminal device. Once the functional device is within the first slot and the terminal device is within the second slot, the functional device can establish a communication connection with the terminal device. Furthermore, once the functional device is within the first slot of the supporting case, the functional device and the connection device are integrated, making it more convenient for users to carry.

[0058] It should be noted that after the functional device 010 is located in the first slot K1 of the supporting shell 100 and the terminal device 020 is located in the second slot K2 of the supporting shell 100, the functional device 010 and the terminal device 020 can be communicated and connected through wireless communication, or the functional device 010 and the terminal device 020 can be communicated and connected through wired communication.

[0059] When the functional device 010 and the terminal device 020 are connected via wireless communication, the functional device 010 may include a first wireless communication module, and the terminal device 020 may include a second wireless communication module corresponding to the first wireless communication module. After the functional device 010 is located in the first slot K1 of the supporting case 100 and the terminal device 020 is located in the second slot K2 of the supporting case 100, the functional device 010 and the terminal device 020 can be connected via communication between the first wireless communication module and the second wireless communication module.

[0060] For example, the first wireless communication module and the second wireless communication module may include: a Bluetooth module, a cellular network module, a mobile hotspot, ZigBee, an ultra-wideband (Ultra WideBand, UWB) or a near field communication (English name: Near Field Communication, abbreviated: NFC) module, etc.

[0061] In the case where the functional device 010 and the terminal device 020 are connected via wired communication, please refer to Figure 3 , Figure 3 2 is a schematic diagram of the structure of another connection device provided in an embodiment of the present application. The communication connection component 200 in the connection device 000 may have a first connection member 201 and a second connection member 202 at each end. The first connection member 201 in the communication connection component 200 may be located in the first slot K1 of the support shell 100, and the second connection member 202 may be located in the second slot K2 of the support shell 100. After the functional device 010 is located in the first slot K1 of the support shell 100, the functional device 010 can be communicatively connected with the first connection member 201, and after the terminal device 020 is located in the second slot K2 of the support shell 100, the terminal device 020 can be communicatively connected with the second connection member 202. To this end, after the functional device 010 is located in the first slot K1 of the support shell 100 and the terminal device 020 is located in the second slot K2 of the support shell 100, the functional device 010 and the terminal device 020 can be communicatively connected via the first connection member 201 and the second connection member 202 in the communication connection component 200.

[0062] Optional, such as Figure 4 and Figure 5 As shown, Figure 4 This is a front view of a functional device provided in an embodiment of the present application. Figure 5 This is a bottom view of a functional device provided in an embodiment of the present application. Functional device 010 may include a third connector 011 adapted to mate with first connector 201 in communication connection assembly 200. Functional device 010, located within first slot K1 of support housing 100, can achieve communication connection with first connector 201 through communication connection between first connector 201 and third connector 011.

[0063] Similarly, if Figure 6 and Figure 7 As shown, Figure 6 is a front view of a terminal device provided in an embodiment of the present application, Figure 7This is a bottom view of a terminal device provided in an embodiment of the present application. Terminal device 020 may include a fourth connector 021 that mates with second connector 202 in communication connection assembly 200. Once terminal device 020 is positioned within second slot K2 of support housing 100, terminal device 020 can establish a communication connection with second connector 202 via the fourth connector 021.

[0064] It should be noted that the first connector 201 and the second connector 202 in the communication connection assembly 200 may be Universal Serial Bus (USB) male interfaces. The third connector 011 in the functional device 010 may be a USB female interface adapted to the first connector 201, which is a USB male interface. The fourth connector 021 in the terminal device 020 may be a USB female interface adapted to the second connector 202, which is a USB male interface.

[0065] Optional, please refer to Figure 3 and Figure 8 , Figure 8 A schematic diagram of the structure of another connection device provided in an embodiment of the present application. The support housing 100 in the connection device 000 may further include a first opening O1 that communicates with the second slot K2. The terminal device 020 can be slid into the second slot K2 through the first opening O1, or removed from the second slot K2 through the first opening O1. In other words, the terminal device 020 can be detachably connected to the support housing 100.

[0066] Optional, such as Figure 3 As shown, the supporting case 100 may also have a third opening O3 that communicates with the first slot K1. The functional device 010 can be slid into the first slot K1 through the third opening O3, or removed from the first slot K1 through the third opening O3. In other words, the functional device 010 can be detachably connected to the supporting case 100.

[0067] Thus, when it is necessary to implement the function corresponding to the function information to be implemented sent by the terminal device 020 through the functional device 010, the user can slide the functional device 010 into the first slot K1 of the supporting shell 100 to establish a communication connection between the functional device 010 and the first connector 201 in the communication connection component 200. At the same time, the user can slide the terminal device 020 into the second slot K2 of the supporting shell 100 to establish a communication connection between the terminal device 020 and the second connector 202 in the communication component 200. In this way, the communication connection between the functional device 010 and the terminal device 020 is established, thereby allowing the functional device 010 to interact with the terminal device 020.

[0068] In this application, if Figure 3 and Figure 8 As shown, the supporting shell 100 may include a supporting shell body 110 and a clip 120 fixedly connected to the supporting shell body 110. The clip 120 of the supporting shell 100 may have a second slot K2 and a first opening O1. After the terminal device 020 is positioned within the second slot K2 of the clip 120, the clip 120 may be used to clip the terminal device 020 into the second slot K2. This ensures that the terminal device 020 remains stably positioned within the second slot K2 of the clip 102, preventing the terminal device 020 from falling out of the second slot K2, further ensuring the stability of the communication connection between the terminal device 020 and the second connector 202 of the communication connection assembly 200.

[0069] It should be noted that the supporting shell body 110 in the supporting shell 100 may have a first groove body K1 and a third opening O3 communicating with the first groove body K1 .

[0070] Optional, such as Figure 3 As shown, the clip 120 in the supporting case 100 may further have a second opening O2 that communicates with the second slot K2. The plane where the first opening O1 of the clip 120 is located may intersect with the plane where the second opening O2 is located. For example, the plane where the first opening O1 of the clip 120 is located may intersect perpendicularly with the plane where the second opening O2 is located. Furthermore, the second opening O2 of the clip 120 may be located on a side of the clip 120 facing away from the supporting case body 110.

[0071] It should be noted that after the terminal device 020 slides into the second slot K2 through the first opening O1, the display screen of the terminal device 020 can be exposed through the second opening O2 of the snap-on component 120, so that the user can send function information to be implemented to the functional device 010 by operating the display screen of the terminal device 020.

[0072] In the present application, when the terminal device 020 is a non-folding device, the size of the second slot K2 of the clip 120 for accommodating the terminal device 020 can be adapted to the size of the non-folding device so that the terminal device 020 can be completely located in the second slot K2 of the clip 120.

[0073] Optional, such as Figure 6 and Figure 7As shown, when the terminal device 020 is a foldable device, for example, when the terminal device 020 is a foldable mobile phone, the foldable device may include: a first main body 023, a second main body 024, and a hinge 025. The first main body 023 and the second main body 024 can rotate relative to each other via the hinge 025, so that the foldable device can be folded or unfolded. The second slot K2 of the clamping member 120 can be used to accommodate the first main body 023, that is, the foldable device can be connected to the connection device 000 via the first main body 023 located in the second slot K2. After the first main body 023 is located in the second slot K2, the second main body 024 can be located outside the second slot K2 and can rotate relative to the first main body 023, so that the foldable device is in a folded state or an unfolded state.

[0074] In this way, when the first main body 023 is located in the second slot K2 and the folding device is in the unfolded state, the display screen of the folding device can be exposed through the second opening O2 of the snap-on component 120, so that the user can trigger the folding device to send the function information to be implemented to the functional device 010 by operating the display screen.

[0075] It should be noted that the second main body 024 can include a secondary screen 022, and this secondary screen 022 can be positioned opposite the display screen of the foldable device. Thus, when the first main body 023 is located within the second slot K2 and the terminal device 020 is in the folded state, the secondary screen 022 of the second main body 024 can be located on the side of the second main body 024 facing away from the first main body 023. To this end, the user can trigger the foldable device to send information about the function to be implemented to the functional device 010 by operating the secondary screen 022.

[0076] It should also be noted that the functional device 010 is relatively small overall. For example, the functional device 010 may be a small photo printer, also known as a pocket photo printer. Furthermore, if the terminal device is a foldable device, and the foldable device is small in size, the foldable device can be placed into the second slot K2 of the connection device 000 while it is folded. This ensures that the overall size of the connection device 000, to which the terminal device 020 is connected, is relatively small, making it more portable.

[0077] In the present application, the support shell 100 in the connection device 000 may further include a friction layer fixedly connected to the inner wall of the first slot K1 of the support shell 100. After the functional device 010 is located within the first slot K1 of the support shell 100, a certain amount of friction may exist between the functional device 010 and the friction layer, so that after the functional device 010 is located within the first slot K1, the user needs to use considerable force to remove the functional device 010 from the first slot K1. This prevents the functional device 010 located within the first slot K1 from automatically falling out of the first slot K1 of the support shell 100. It should be noted that the friction layer in the support shell 100 may be made of rubber.

[0078] Optional, please refer to Figure 9 , Figure 9 This is a schematic structural diagram of another connection device provided in an embodiment of the present application. The support shell body 110 of the connection device 000 may include: a first support plate 101 and a second support plate 102 disposed oppositely, two side plates 103 disposed oppositely, and a bottom plate 104. The two side plates 103 and the bottom plate 104 in the support shell 100 may be located between the first support plate 101 and the second support plate 102. The two opposite sides of each side plate 103 in the support shell 100 may be fixedly connected to the first support plate 101 and the second support plate 102, respectively. The bottom plate 104 in the support shell 100 may be fixedly connected to the same side of the first support plate 101, the second support plate 102, and the two side plates 103. The side of the first support plate 101 facing away from the second support plate 102 may have a second groove K2, that is, the clamping member 110 may be located on the side of the first support plate 101 facing away from the second support plate 102. The first support plate 101 , the second support plate 102 , the two side plates 103 and the bottom plate 104 may be used to enclose a first trough body K1 , and the third opening O3 may be disposed opposite to the bottom plate 104 .

[0079] It should also be noted that the friction layer located on the inner wall of the first trough body K1 in the support shell 100 can be fixedly connected to the first support plate 101 and the second support plate 102 , and / or can be fixedly connected to the two side plates 103 .

[0080] Optional, such as Figure 9As shown, the ends of the two side panels 103 in the support case 100 facing the third opening O3 may have an escape opening O4 that communicates with the first slot K1. That is, the ends of the two side panels 103 in the support case 100 facing away from the bottom plate 104 are closer to the bottom plate 104 than the ends of the first support panel 101 and the second support panel 102 in the support case 100. Thus, after the functional device 010 is positioned within the first slot K1 of the support case 100, a portion of the functional device 010 can be exposed through the escape opening O4. To this end, a user can apply force to the functional device 010 through the portion of the functional device 010 exposed through the escape opening O4 to overcome the friction between the functional device 010 and the friction layer, allowing the functional device 010 to be removed from the first slot K1. The provision of the escape opening O4 in the support case 100 thus facilitates the user's removal of the functional device 010 from the first slot K1.

[0081] In this application, if Figure 9 As shown, the support housing 100 in the connection device 000 may further include a receiving member 105. The receiving member 105 is located on the side of the first slot K1 facing away from the second slot K2. The receiving member 105 may have a receiving slot K3 for accommodating a card. The card may be a photo, document, or label.

[0082] For example, the receiving member 105 in the supporting shell 100 may be fixedly connected to a side of the second supporting plate 102 facing away from the first supporting plate 101 .

[0083] It should be noted that the container 105 may have a fourth opening O5 connected to the receiving slot K3, and the user can put the card into the receiving slot K3 of the container 105 through the fourth opening O5, or can take the card out of the receiving slot K3 through the fourth opening O5.

[0084] It should also be noted that the card located in the receiving slot K3 of the receiving member 105 can be an NFC card, access control card, or bank card. Thus, after the terminal device 020 is located in the second slot K2 of the supporting shell 100, the user can carry the terminal device 020 directly through the connection device 000 and use the NFC card or access control card directly through the receiving member 105. Alternatively, the card located in the receiving slot K3 of the receiving member 105 can be a decorative card that can be used to enhance the appearance of the connection device 000.

[0085] It should also be noted that, when the functional device 010 is a portable printing device, the card located in the receiving slot K3 of the receiving member 105 can also be: a calibration card for calibrating the color of photos printed by the portable printing device, or a printing card without photo content, or photos, documents or labels printed by the portable printing device.

[0086] Optionally, in the case where the functional device 010 is a portable printing device, the portable printing device may have a printing outlet O6, and the photos, documents or labels printed by the portable printing device may be taken out through the printing outlet O6.

[0087] When the functional device 010 and the terminal device 020 are connected via wired communication, the print outlet O6 of the portable printing device located in the first slot K1 can be arranged opposite to the bottom plate 104 of the supporting shell 100. In this way, the print outlet O6 of the portable printing device can be exposed through the third opening O3 of the supporting shell 100.

[0088] In the case where the functional device 010 and the terminal device 020 are communicated via wireless communication, compared to a wired communication connection, there is no need to set a first connecting member in the first slot K1 of the support shell 100. In this way, the print outlet O6 of the portable printing device can be set toward the bottom plate 104, and the bottom plate 104 can have an opening adapted to the print outlet O6 of the portable printing device, so that the print outlet O6 of the portable printing device can be exposed through the opening of the bottom plate 104.
