In the first charging state, the shutter 23 covers the outlet 14, with the charging contact 50 inside the housing 10; in the second charging state, the charging connector 50 is exposed outside the housing 10 after the inner housing 20 slides for a distance relative to the housing 10, the charging interface of the electronic device 2000 is inserted into the charging connector 50, the end of the electronic device 2000 abuts against the connecting portion 22, one side surface of the electronic device 2000 abuts against the housing 10, and the opposite side surface of the electronic device 2000 further abuts against the shielding portion 23, so that the electronic device 2000 is obliquely supported, and a user can see the display information of the electronic device 2000 without using both hands.
In one embodiment, the shield 23 is adapted to be an interference fit with the outlet 14, i.e. depending on the amount of interference of the shaft with the bore, which after assembly causes an elastic pressure between the surfaces of the parts, thereby obtaining a tight coupling. Specifically, in the first charging state, the shielding portion 23 is in interference fit with the outlet 14, so that the outer case 10 and the inner case 20 are fixed to each other, and thus the user can draw out the inner case 20 from the outer case 10 without any tool, which improves the convenience of replacing the dry battery 200.
In another embodiment, the inner housing 20 further comprises a fitting portion 24, the fitting portion 24 is connected with the shielding portion 23, and the fitting portion 24 is used for interference fit with the outlet 14. Specifically, in the first charging state, the fitting portion 24 is in interference fit with the outlet 14, and the shielding portion 23 covers the outlet 14, so that the outer shell 10 and the inner shell 20 are fixed to each other, and the outer shell 10 is in a closed state, so that a user can draw out the inner shell 20 from the outer shell 10 without using any tool, thereby improving the convenience of replacing the dry battery 200.
Optionally, the emergency power bank 100 of the present application further includes an elastic member 60, the elastic member 60 may be a spring, the elastic member 60 may also be a resilient plate, opposite ends of the elastic member 60 are respectively connected with the shielding portion 23 and the outer housing 10, in the first charging state, the inner housing 20 is assembled inside the outer housing 10, the inner housing 20 is fixed relative to the outer housing 10 in an interference fit manner, at this time, the elastic member 60 is in a compressed state, when a user needs to pull out the inner housing 20, the user only needs to push and press the shielding portion 23 with force, so that the spring is further compressed, when the user cancels the pushing force, the elastic force of the spring automatically pushes out the inner housing 20, and thus the user can pull out the inner housing 20 from the outer housing 10 without any tool, thereby improving convenience of replacing the dry battery 200.
The above description is only an embodiment of the present invention, and not intended to limit the scope of the present invention, and all modifications of equivalent structures and equivalent processes performed by the present specification and drawings, or directly or indirectly applied to other related technical fields, are included in the scope of the present invention.
