Description

TECHNICAL FIELD

[0001] The utility model relates to the field technology of electronic equipment accessories especially refers to a protective sheath with external keyboard. BACKGROUND

[0002] With the popularity of mobile devices, especially the wide application of tablet computers (such as iPad), users have higher requirements for the functionality and convenience of the device. As an important input device, the external keyboard can significantly improve the productivity and use experience of the tablet computer.

[0003] For users who often need to input a large amount of text, the virtual keyboard of the iPad has many limitations. The virtual keyboard keys are small, easy to be touched by mistake when inputting quickly, and lack the tactile feedback of a physical keyboard, which can easily cause finger fatigue and make it difficult to improve input efficiency. Although the external keyboard can effectively solve these problems and significantly improve input speed and accuracy, the traditional connection method of the external keyboard and the iPad brings many inconveniences to the user.

[0004] Under the traditional connection method, if the user wants to connect the external keyboard, he often needs to manually plug in or pull out the data line or perform complex Bluetooth pairing operations. The data line connection is not only limited by the length of the cable, but also may be damaged due to improper operation during plugging and unplugging; Bluetooth pairing requires a series of processes such as waiting for the search device, inputting the pairing code, and takes a long time. More inconveniently, when the user needs to temporarily interrupt the use of the keyboard and use the iPad for touch operation, he has to repeat the tedious disconnection steps. This tedious connection and disconnection process greatly affects the user experience when frequently switching between use scenarios.

[0005] Therefore, it is necessary to study a new technical solution to solve the above problems. CONTENT OF THE UTILITY MODEL

[0044] A protective case with an external keyboard includes a case body 10, a keyboard 20, an adapter component 30, and a driver component 40.

[0045] The sleeve 10 has a receiving cavity 11 for placing electronic devices;

[0046] Preferably, the sleeve 10 is further provided with a clearance 12 relative to the driving member 41, and at least a portion of the driving member 41 is exposed outside the clearance 12. Preferably, the sleeve 10 is also provided with a control button 13, which is made of TPU material. The control button 13 is arranged similarly to the buttons on an electronic device.

[0047] The keyboard 20 is connected to the sleeve 10; an adapter plate 21 is provided at one end of the keyboard 20;

[0048] The adapter assembly 30 is movably mounted on the housing 10. The adapter assembly 30 includes at least a converter 31 connected to the keyboard 20 and a connector 32 for connecting the keyboard 20 to an electronic device. The connector 32 is positioned near the receiving cavity 11. Preferably, the adapter assembly 30 further includes a data cable 33, and the converter 31 further includes a PCB board 34. One end of the data cable 33 is connected to the adapter board 21, and the other end is electrically connected to the PCB board 34. The connector 32 is electrically connected to the PCB board 34. The design of the connector 32 ensures high-speed data transmission and stable power supply, avoiding the instability of traditional Bluetooth connections. In this embodiment, a wireless connection to the keyboard 20 can also be used, requiring only the integration of compatible electronic components on the adapter board 21 and the PCB board 34. This wireless connection method is well-known in the art and will not be described in detail here.

[0049] The drive component 40 is movably disposed on the converter 31. The drive component 40 can drive the converter 31 to move, so as to switch the converter 31 between a connected state and a released state. In the connected state, the drive component 40 can drive the connector 32 of the converter 31 to connect with the electronic device. In the released state, the drive component 40 can drive the connector 32 of the converter 31 to disconnect from the electronic device.

[0050] Preferably, the sleeve 10 is further provided with a mounting cavity 14 communicating with the receiving cavity 11. The converter 31 is movably disposed in the mounting cavity 14. In the connected state, the driving component 40 can drive the converter 31 to press against the inner wall of the mounting cavity 14, so that the connector 32 is connected to the electronic device. In the released state, the driving component 40 can drive the converter 31 away from the inner wall of the mounting cavity 14 and at least partially exposed outside the sleeve 10, so that the connector 32 is disconnected from the electronic device.

[0051] Preferably, the drive assembly 40 includes at least a drive member 41 and a first elastic member 42, and the converter 31 is provided with an abutment groove; one end of the first elastic member 42 abuts against the inner wall surface of the mounting cavity 14, and the other end of the first elastic member 42 abuts against the abutment groove. The drive member 41 is movably disposed on the converter 31. In the released state, the drive member 41 is triggered to move away from the receiving cavity 11, so that the converter 31 releases energy through the first elastic member 42 and moves away from the inner wall surface of the mounting cavity 14 and is at least partially exposed outside the sleeve 10. In the connected state, the drive member 41 is triggered to move closer to the receiving cavity 11, so that the converter 31 stores energy through the first elastic member 42 and abuts against the inner wall surface of the mounting cavity 14.

[0052] The converter 31 is provided with a locking groove 35, and the driving member 41 is provided with a locking part 44 for matching the locking groove 35. The driving assembly 40 also includes a second elastic member 43 for providing a reset force to the driving member 41. The driving member 41 is movably disposed on the converter 31, so that the locking part 44 can be selectively connected to the locking groove 35, so that in the connected state, the locking part 44 and the locking groove 35 form a lock, ensuring the stability of the connection between the connector 32 and the electronic device.

[0053] Preferably, the PCB board 34 is also electrically connected to a headphone adapter 36, allowing users to connect headphones while using the keyboard 20 and enjoy high-quality audio output, meeting the needs of various usage scenarios.

[0054] Preferably, the PCB board 34 is also electrically connected to a charging interface 37, which supports charging the iPad while using the keyboard 20, thus extending the device's usage time.

[0055] For example, the charging port 37 and the headphone jack are designed with independent circuit channels. During PCB layout, the charging circuit and audio circuit are routed separately to avoid signal interference. In actual installation, the power and ground lines of the charging circuit should be as thick as possible to reduce resistance and ensure stable charging current transmission. The audio circuit, on the other hand, should use shielded cables or have a shielding layer on the PCB to prevent external electromagnetic interference from affecting the audio signal and ensure clear sound quality.

[0056] Alternatively, in the circuit design, an independent protection circuit can be set for each interface. For the charging interface 37, overvoltage protection, overcurrent protection and short circuit protection circuits can be added. When the charging voltage is too high or the current is too large, the protection circuit will automatically cut off the power supply to prevent damage to electronic equipment and PCB board. For the headphone interface, an electrostatic protection circuit can be set to avoid electrostatic damage to the audio chip.

[0057] Alternatively, the charging port 37 and the headphone jack connector 32 can be surface-mount soldered onto the PCB board. This process offers high precision and allows for high-density circuit layout. During SMT (Surface Mount Technology), solder paste is first printed on the PCB board, then the connector 32 is accurately placed in the corresponding position. Reflow soldering melts the solder paste, achieving both electrical connection and mechanical fixation between the connector 32 and the PCB board. The surface-mount connector 32 is small, effectively saving PCB board space and allowing for a thinner and lighter protective sleeve design.

[0058] The key design feature of this invention lies in its structural design of an adapter component and a drive component. The adapter component includes at least a converter and a connector. The drive component can move the converter to switch it between a connected state and a released state. In the connected state, the drive component can connect the converter's connector to the electronic device. In the released state, the drive component can disconnect the converter's connector from the electronic device. This allows users to quickly connect or disconnect the keyboard from the electronic device, simplifying operation without complicated steps, improving efficiency, streamlining device connection processes, and enhancing ease of use. Furthermore, the connector design is compact and highly integrated, reducing cable clutter and making it easy to carry and store, suitable for mobile office work and daily use.

[0059] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
