[0025] 1 to 6, the mobile phone protective case of the present invention, which can be externally attached to a device, includes a protective case body 1, a circuit board 2, and an external module.

[0026] Specifically, a first cavity 9 for accommodating a mobile phone 4 is formed on one side of the protective case body 1, and a second cavity is formed inside the protective case body 1. A circuit board 2 is installed in the second cavity. The external module includes an internal interface 32 connected to the circuit board 2 and at least one external interface 5. The internal interface 32 is located in the first cavity 9 and is for connecting to a charging port of the mobile phone 4, and the external interface 5 is located in the first cavity 9 and / or the second cavity and is for connecting to an external device, thereby enabling the mobile phone 4 to transmit power and / or transmit data to the external device.

[0027] 2, the protective case body 1 semi-encloses the external mobile phone 4 during use to provide physical protection. Alternatively, the protective case body 1 may be a hard protective case or a soft protective cover. The mobile phone 4 may be another electronic device such as a tablet computer.

[0028] Preferably, the circuit board 2 and the external module are both installed in the second cavity, so as to be protected by the protective case body 1 and avoid damage caused by collision during use. The external interface 5 may be exposed from the side wall of the second cavity, so as to be used for connecting to external devices.

[0029] As can be understood, when the present invention is used, the protective case body 1 is connected to an external mobile phone 4, for example, the protective case body 1 is removably fitted to the mobile phone 4, and the internal interface 32 is connected to the charging port of the mobile phone 4; at this time, the external interface 5 can be connected to an external device to form a transmission path between the mobile phone 4 and the external device, thereby enabling the mobile phone 4 and the external device to transmit power and / or transmit data.

[0030] The present invention can extend one or more external interfaces 5 from the mobile phone 4, enhancing the external attachment function of the mobile phone 4 to devices. Optionally, the number and type of the external interfaces 5 may be adaptively set according to actual circumstances, and there is no specific limitation thereon. Exemplarily, the at least one external interface 5 may include a USB interface, and / or an HDMI interface, and / or an Ethernet interface.

[0031] The USB interface may include, for example, a USB-A interface and a USB-C interface. The USB-C interface may be configured to support PD fast charging, and if the external device is a power supply device, the power supply device can be connected to the USB-C interface to quickly charge the mobile phone 4. And if the external device is another electronic device or memory, the external device can be connected to the USB-A interface to realize a data connection between the external device and the mobile phone 4, thereby facilitating data transmission between the devices. Optionally, the USB-A interface may be configured to support any one of the USB 3.0 protocol, the USB 2.0 protocol, and the USB 1.0 protocol.

[0032] In one specific embodiment, the protective case body 1 is further provided with an expansion memory interface 6 for connecting to an external memory, and the expansion memory interface 6 is connected to the circuit board 2. In actual use, the expansion memory interface 6 is connected to the external memory, allowing the external memory to be connected to the mobile phone 4 via the circuit board 2 and the internal interface 32, thereby realizing the function of expanding the storage space of the mobile phone 4. The power of the mobile phone 4 can be transmitted to the expansion memory interface 6 via the internal interface 32 and the circuit board 2, thereby supplying power to the external memory.

[0033] For example, the extended memory interface 6 may be a TF slot, and the external memory is a TF card. A TF card control unit may be installed on the circuit board 2, and the TF slot may be connected to the TF card control unit.

[0034] Further, referring to FIG. 1, FIG. 3 and FIG. 6, a first boss 11 may be formed on the side of the protective case body 1 away from the first cavity 9. Specifically, the expansion memory interface 6 is installed on the first boss 11, and for example, the expansion memory interface 6 may be located inside the first boss 11, and a cutout 121 is opened at a position corresponding to the expansion memory interface 6 on the side wall of the first boss 11, so that an external memory can be inserted into the expansion memory interface 6 through the cutout 121. Preferably, a stopper sheet 10 may be further installed at a position corresponding to the cutout 121 on the first boss 11, and the stopper sheet 10 can block the cutout 121 to provide a protective function. A cable 7 is further installed inside the first protective case body 1, and the expansion memory interface 6 is connected to the circuit board 2 through the cable 7. Preferably, the cable 7 may be a flexible flat cable, so that the structure of the protective case body 1 can be made more compact.

[0035] In addition, a second boss 12 is further formed on the side of the protective case body 1 away from the first cavity 9, the second cavity may be located on the second boss 12, the circuit board 2 and the external module are both installed on the second boss 12, and the external interface 5 is exposed from the side wall of the second boss 12 so that the external device can be inserted.

[0036] 1 again, in one embodiment, the first boss 11 and the second boss 12 may be located at opposite ends of the protective case body 1. Specifically, the camera hole 13 may be opened at one end of the protective case body 1, and the first boss 11 may be formed at a position close to the camera hole 13 of the protective case body 1, while the second boss 12 is formed at an end of the protective case body 1 away from the camera hole 13, that is, at an end of the protective case body 1 corresponding to the charging port of the external mobile phone 4. In this way, a part of a smooth surface exists between the first boss 11 and the second boss 12 on the protective case body 1, and the user can easily grip the smooth surface, and an unpleasant gripping feeling due to the protrusion of the boss is avoided.

[0037] In addition, preferably, the first boss 11 and the second boss 12 further have the same protruding height; as can be understood, such a design can maintain stability when the protective case body 1 is placed on a horizontal surface, avoid shaking caused by the difference in boss height, and improve the user experience.

[0038] Exemplarily, the protruding height of each of the first boss 11 and the second boss 12 may be between 5 mm and 20 mm. Optionally, the boss height may be adaptively set according to the number and type of the external interfaces 5. For example, when the protruding height is 5 mm, one row of USB-C interfaces may be exposed on the second boss 12, whereas when the protruding height is 20 mm, multiple rows of USB-A interfaces may be exposed on the second boss 12.

[0039] In one specific embodiment, the protective case body 1 may be provided with a touch panel and / or buttons 8 that are signal-connected to the circuit board 2. Referring to FIG. 1 , in an embodiment in which a first boss 11 and a second boss 12 are formed, the buttons 8 may be provided on the second boss 12.

[0040] In one situation, the button 8 may be configured to control the connection between the mobile phone 4 and a specific external device. Specifically, a user can press the button 8 to cause the button 8 to send a control signal to the circuit board 2, and the circuit board 2 controls the connection between the internal interface 32 and the specific external interface 5 to be turned on based on the control signal, thereby realizing the function of connecting the mobile phone 4 to the specific external device. For example, if the external interface 5 includes an interface 1, an interface 2, and an interface 3, pressing the button 8 can cause the internal interface 32 to be repeatedly connected to the interfaces 1 to 3.

[0041] In another situation, the button 8 can also be configured to determine the connection relationship between the mobile phone 4 and multiple external devices, that is, based on the above situation, it can further connect the external devices connected to different external interfaces 5. Specifically, when the external interface 5 includes an interface 1 and an interface 2, and both the interface 1 and the interface 2 are connected to external devices, the mobile phone 4 is initially set to connect to the external device of the interface 1 in the initial state, and the mobile phone 4 can transmit data to the external device of the interface 1; when the button 8 is pressed, the mobile phone 4 is connected to the external device of the interface 2, and when the button 8 is pressed again, the external device of the interface 1 is connected to the external device of the interface 2 at this time, so that the two external devices can transmit data to each other.

[0042] In other embodiments, the buttons 8 may be replaced by a touch panel, or other extended functions may be added to control the disconnection and connection between the mobile phone 4 and an external device by the touch panel, and are not limited thereto. Optionally, the touch panel may be a capacitive touch panel or a resistive touch panel.

[0043] 4 and 5, in one specific embodiment, the internal interface 32 is fixed to the protective case body 1, and the internal interface 32 is connected to the circuit board 2 via a flexible flat cable 31. The flexible flat cable 31 can be located inside the protective case body 1, which makes the present invention more elegant.

[0044] Optionally, the internal interface 32 may include any one of a Type-C male terminal, a Micro-USB male terminal, and a Lightning male terminal. The type of the internal interface 32 may be adaptively set according to the type of the charging port of the mobile phone 4.

[0045] In one specific embodiment, the circuit board 2 further includes a timing module connected thereto, for calculating the duration of disconnection / connection between the internal interface 32 and the mobile phone 4. Specifically, when the internal interface 32 and the mobile phone 4 are disconnected / connected for more than a predetermined time, the timing module can send a control signal to the circuit board 2, and the circuit board automatically enters a sleep state based on the control signal, thereby saving power.

[0046] In short, the mobile phone protective case of the present invention, which can be externally attached to a device, has an external module installed in the protective case main body 1, so that the external interface 5 of the external module can be connected to an external device, and the internal interface 32 of the external module can be connected to the mobile phone 4 protected by the protective case main body 1. As a result, the protective case of the present invention can not only physically protect the mobile phone 4, but also connect the mobile phone 4 to an external device, and the mobile phone 4 can transmit power and / or data to the external device through the external module, making it convenient for the mobile phone to be connected to multiple devices.
