[0036] Please refer to Figures 1 to 6 The present invention provides a mobile phone protective case that can be connected to external devices, comprising: a protective case body 1, a circuit board 2, and an external module.

[0037] Specifically, a first cavity 9 for accommodating the mobile phone 4 is formed on one side of the protective case body 1, and a second cavity is located inside the protective case body 1. A circuit board 2 is disposed 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 used to connect to the charging port of the mobile phone 4. The external interface 5 is located in the first cavity 9 and / or the second cavity and is used to connect to an external device, enabling the mobile phone 4 to perform power transmission and / or data transmission with the external device.

[0038] For example, the protective shell body 1 may be in the form of Figure 2 The semi-enclosed structure shown provides physical protection by partially enclosing the mobile phone 4 within the protective case body 1. Optionally, the protective case body 1 can be a rigid protective case or a flexible protective sleeve. The mobile phone 4 can also be a tablet computer or other electronic devices.

[0039] Preferably, both the circuit board 2 and the external module are housed within the second cavity, protected by the protective housing 1 to prevent damage from impacts during use. The external interface 5 can protrude from the side wall of the second cavity for connecting external devices.

[0040] Understandably, when using this utility model, the protective case body 1 is connected to the external mobile phone 4. For example, the protective case body 1 is detachably fitted onto the mobile phone 4, and the inner interface 32 is connected to the charging port of the mobile phone 4. At this time, the outer interface 5 can be connected to the external device, thereby forming a transmission path between the mobile phone 4 and the external device, so that the mobile phone 4 and the external device can transmit power and / or data.

[0041] This invention enables a mobile phone 4 to have one or more external interfaces 5, thereby improving the ability of the mobile phone 4 to connect to external devices. Optionally, the number and type of external interfaces 5 can be adapted to the actual situation and are not specifically limited thereto. For example, the at least one external interface 5 may include a USB interface, and / or an HDMI interface, and / or an Ethernet interface.

[0042] The USB interface may include, for example, a USB-A interface and a USB-C interface. The USB-C interface can be configured to support PD fast charging. When the external device is a power supply, it can be connected to the USB-C interface to quickly charge the phone 4. When the external device is another electronic device or storage device, it can be connected to the USB-A interface to achieve data connection between the external device and the phone 4, facilitating data transfer between the devices. Optionally, the USB-A interface can be configured to support any one of the following protocols: USB 3.0, USB 2.0, and USB 1.0.

[0043] In one specific embodiment, the protective case body 1 is further provided with an expansion storage interface 6 for connecting to an external memory, which is connected to the circuit board 2. In actual use, the expansion storage interface 6 connects to the external memory, allowing the external memory to connect 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 storage interface 6 via the internal interface 32 and the circuit board 2 to power the external memory.

[0044] For example, the extended storage interface 6 can be a TF card slot, in which case the external storage device is the TF card. A TF card control unit can be provided on the circuit board 2, and the TF card slot can be connected to the TF card control unit.

[0045] Further, please refer to Figure 1 , Figure 3 and Figure 6 A first protrusion 11 may be formed on the side of the protective shell body 1 opposite to the first cavity 9. Specifically, an expansion storage interface 6 is disposed on the first protrusion 11. Exemplarily, the expansion storage interface 6 may be located inside the first protrusion 11. A notch 121 is provided on the side wall of the first protrusion 11 corresponding to the position of the expansion storage interface 6, so that an external memory can be inserted into the expansion storage interface 6 through the notch 121. Preferably, a baffle 10 may also be provided on the first protrusion 11 corresponding to the position of the notch 121, which can cover the notch 121 and play a protective role. A cable 7 is also provided inside the first protective shell body 1, and the expansion storage 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 shell body 1 can be more compact.

[0046] Furthermore, a second protrusion 12 is formed on the side of the protective shell body 1 opposite to the first cavity 9. The second cavity can be located in the second protrusion 12. The circuit board 2 and the external module are both set in the second protrusion 12. The external interface 5 is exposed from the side wall of the second protrusion 12 for external devices to be plugged in.

[0047] Furthermore, in one embodiment, please refer again to Figure 1 The first protrusion 11 and the second protrusion 12 can be located at opposite ends of the protective case body 1. Specifically, a camera hole 13 can be formed at one end of the protective case body 1. The first protrusion 11 can be formed on the protective case body 1 near the camera hole 13, while the second protrusion 12 is formed on the protective case body 1 at the end away from the camera hole 13, that is, at the end of the protective case body 1 corresponding to the charging port of the external mobile phone 4. Thus, there will be a flat surface between the first protrusion 11 and the second protrusion 12 on the protective case body 1. This flat surface is convenient for users to grip and avoids poor grip caused by protruding protrusions.

[0048] In addition, preferably, the first boss 11 and the second boss 12 have the same protrusion height. Understandably, this design allows the protective shell body 1 to remain stable when placed on a horizontal surface, avoiding shaking caused by inconsistent boss heights and improving the user experience.

[0049] For example, the protrusion height of both the first boss 11 and the second boss 12 can be between 5mm and 20mm. Optionally, the boss height can be adaptively set according to the number and type of external interfaces 5. For example, when the protrusion height is 5mm, a row of USB-C interfaces can be exposed on the second boss 12, while when the protrusion height is 20mm, multiple rows of USB-A interfaces can be exposed on the second boss 12.

[0050] In one specific embodiment, the protective housing body 1 may be provided with a touch panel and / or buttons 8 for the signal connection circuit board 2. Please refer to... Figure 1 In an embodiment where a first protrusion 11 and a second protrusion 12 are formed, the button 8 may be disposed on the second protrusion 12.

[0051] In one scenario, button 8 can be configured to control the connection between mobile phone 4 and a specific external device. Specifically, by pressing button 8, the user sends a control signal to circuit board 2. Based on this control signal, circuit board 2 controls the connection between internal interface 32 and a specific external interface 5, thereby enabling mobile phone 4 to connect to the specific external device. For example, if external interface 5 includes interface 1, interface 2, and interface 3, pressing button 8 will cause internal interface 32 to cycle through interface 1 to interface 3.

[0052] In another scenario, button 8 can also be configured to determine the connection relationship between mobile phone 4 and multiple external devices. That is, based on the above, it further enables connection between external devices connected to different external interfaces 5. Specifically, if external interface 5 includes interface 1 and interface 2, and both interface 1 and interface 2 are connected to external devices, initially, mobile phone 4 is connected to the external device of interface 1 by default, allowing mobile phone 4 to transmit data to the external device of interface 1. When button 8 is pressed, mobile phone 4 is connected to the external device of interface 2. When button 8 is pressed again, the external device of interface 1 is connected to the external device of interface 2, enabling data transmission between the two external devices.

[0053] In other embodiments, a touch panel may be used instead of button 8, or the touch panel may provide additional extended functions such as controlling the disconnection and connection of the mobile phone 4 with external devices; no specific limitation is made in this regard. Optionally, the touch panel may be a capacitive touch panel or a resistive touch panel.

[0054] In one specific embodiment, please refer to Figure 4 and Figure 5 The inner interface 32 is fixed to the protective shell body 1, and the inner interface 32 is connected to the circuit board 2 through a flexible flat cable 31. The flexible flat cable 31 can be located in the protective shell body 1, thereby making the present invention more aesthetically pleasing.

[0055] Optionally, the internal interface 32 may include any one of a Type-C male connector, a Micro-USB male connector, or a Lightning male connector. The type of the internal interface 32 can be adapted to the charging port type of the mobile phone 4.

[0056] In one specific embodiment, a timing module connected to the circuit board 2 is also included. This timing module is used to calculate the duration of the disconnection between the internal interface 32 and the mobile phone 4. Specifically, when the disconnection between the internal interface 32 and the mobile phone 4 exceeds a preset time, the timing module can send a control signal to the circuit board 2, and the circuit board will automatically enter a sleep state based on the control signal to save power.

[0057] In summary, this utility model provides a mobile phone protective case that can connect to external devices. By setting an external module on the protective case body 1, 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 body 1. Thus, in addition to providing physical protection for the mobile phone 4, this utility model also enables the mobile phone 4 to connect to external devices. The mobile phone 4 can transmit power and / or data to the external device through the external module, providing convenience for multi-device connection of the mobile phone.
