[0002] With the development of technology, tablet computers evolved from mobile phones are gradually entering people's lives. And with the continuous improvement of the functions and the increasingly powerful configuration of tablet computers, tablet computers can meet people's basic needs for mobile phone functions. In addition, due to the large display screen, light weight and convenient carrying of tablet computers, for some tasks that can only be operated by a computer, they can be solved by using a tablet computer. In order to prevent the tablet computer from being accidentally dropped, collided or rubbed with other objects during carrying or use, many people will install a protective cover outside the tablet computer to achieve the protection effect.

[0003] Existing tablet computers can be charged either by connecting an external data cable or by wireless charging. Both charging methods have certain drawbacks. For example, the external data cable is prone to entanglement, which is not beautiful and practical. The voltage of the wireless charging method is slower than that of wired charging, and it is prone to heat generation and overheating, which reduces the battery life of the tablet computer. In addition, when the traditional external charger is charging, the tablet computer cannot be carried around, or when it is inconvenient to charge the tablet computer when using it outside, it will bring a bad user experience to the user.

[0020] The following further describes the present utility model in detail in conjunction with embodiments.

[0021] As Figure 1 and Figure 2 shown, a specific embodiment of a contact charging type Bluetooth keyboard protection case for a tablet computer provided by the present utility model:

[0022] A contact charging type Bluetooth keyboard protection case for a tablet computer includes a protective cover and an inner housing 1. The protective cover is formed by connecting a first cover body 2 and a second cover body 3. The first cover body 2 and the second cover body 3 can move freely at the connection part;

[0023] A crease 4 is provided in the middle and lower part of the first cover body 2. The middle part of the inner housing 1 is detachably installed on the upper part of the first cover body 2. Preferably, the inner housing 1 and the first cover body 2 are connected by a magnetic attraction method. A first magnetic ring 5 is provided in the middle part of the inner housing 1, and a second magnetic ring 6 is provided in the middle part of the first cover body 2. Through the mutual attraction of the first magnetic ring 5 and the second magnetic ring 6, the inner housing 1 is adsorbed and installed on the first cover body 2. The inner housing 1 is used to install a tablet computer. A magnetic male contact 7 is provided in the middle part of the first cover body 2, and a magnetic female contact 8 is provided on the inner housing 1. The magnetic male contact 7 and the magnetic female contact 8 form a magnetic contact charging structure. The magnetic contact charging structure is a prior art and is widely used in charging watches, and its specific structure will not be described in detail; A camera hole 9 is correspondingly opened in the upper part of the inner housing 1 and the first cover body 2, and the position of the camera hole 9 corresponds to the camera of the tablet computer.

[0024] A rechargeable power supply 10 is installed on the protective cover. The magnetic male contact 7 on the first cover body 2 is connected to the rechargeable power supply 10 through a circuit. One end of the rechargeable power supply 10 is provided with a USB interface 11 and a Type-C interface 12. The Type-C interface is used to charge the rechargeable power supply 10, and the USB interface 11 is used to connect a data cable to supply power to other mobile phones or electrical devices. The other end of the rechargeable power supply 10 is provided with a power switch and a power monitoring display screen. The power switch controls the power supply of the rechargeable power supply 10, and the power monitoring display screen can monitor and display the power; The magnetic female contact 8 on the inner housing 1 is connected with a charging connector 13 through a circuit, and this charging connector 13 is used for the tablet computer to connect;

[0025] A Bluetooth keyboard 14 is provided on the second housing 3. Preferably, the Bluetooth keyboard 14 is mounted on the second housing 3 by a magnetic attraction method. Two card slots 15 are also provided on the second housing 3, and the two card slots 15 are arranged side by side at intervals.

[0026] When the protective case of this embodiment is in use, the tablet computer is set inside the inner housing 1.
