The protective housing with the lens cover provided by one embodiment of the utility model comprises a main housing 10, a lens cover 20 and a magnetic attraction assembly, and is suitable for electronic equipment with a rear camera. Referring to fig. 1, a main housing 10 includes a back plate 11, and one side of the back plate 11 forms a receiving chamber 101. The back plate 11 is provided with a lens hole 111 communicating with the accommodating chamber 101, and the back plate 11 includes a positioning plate 112 adjacent to the lens hole 111 in the first direction. The lens cover 20 is slidably coupled to the main housing 10 and is slidable in a first direction to switch between a closed state and an open state. In the closed state, the lens cover 20 covers the lens hole 111. The lens cover 20 is stacked on a side of the positioning plate 112 facing away from the accommodating chamber 101 in the open state. Fig. 1 and 2 show a schematic view of the structure in an open state.

Referring to fig. 3, which is a schematic view of section A-A of fig. 2, the magnetic attraction assembly includes a first magnetic attraction member 31, a second magnetic attraction member 32, and a third magnetic attraction member 33. Wherein the first magnetic attraction member 31 is provided on the lens cover 20. The second magnetic attraction piece 32 is disposed on the positioning plate 112, and in the open state, the second magnetic attraction piece 32 is magnetically attracted to the first magnetic attraction piece 31. The third magnetic attraction piece 33 is provided on the main casing 10, and in the closed state, the second magnetic attraction piece 32 is separated from the first magnetic attraction piece 31, and the third magnetic attraction piece 32 is magnetically attracted to and connected with the first magnetic attraction piece 31. That is, the first magnetic attraction member 31 can be selectively magnetically attracted to one of the second magnetic attraction member 32 and the third magnetic attraction member 33 in association with the sliding of the lens cover 20. The third magnetic member 33 may be disposed at a certain position of the back plate 10 or other suitable positions on the main housing 10 according to the actual position of the first magnetic member 31 in the closed state, and the following embodiments will be specifically illustrated.

Specifically, when the protective casing with the lens cover provided in this embodiment is sleeved on the electronic device, the back surface of the electronic device contacts with the back plate 11, the main body of the electronic device is accommodated in the accommodating cavity 101, and the camera on the electronic device protrudes through the lens hole 111. Referring to fig. 3, when the lens cover 20 is in the open state, the lens cover 20 is stacked on the positioning plate 112, and at this time, the first magnetic attraction member 31 is aligned with the second magnetic attraction member 32 on the positioning plate 112 and can be magnetically attracted to each other, so that the lens cover 20 can maintain the stacked position on the positioning plate 112, i.e., maintain the open state. In the open state, the camera is exposed from the lens hole and can be used for photographing and shooting. When the camera is not required to be used, the lens cover 20 is slid so that the lens cover 20 covers the lens hole 111, that is, is in a closed state, to protect the camera. Referring to fig. 4, the first magnetic attraction member 31 is aligned with the third magnetic attraction member 33 and can be magnetically attracted to each other, so that the lens cover 20 can maintain a position covering the lens hole 111, i.e. maintain a closed state.

In this embodiment, the first magnetic attraction member 31, the second magnetic attraction member 32 and the third magnetic attraction member 33 are disposed at corresponding positions, so that the lens cover 20 can be maintained in an open or closed state by the magnetic attraction effect, so that the lens cover 20 cannot be easily opened to expose the camera when the camera is not required, and the lens cover 20 cannot be easily closed to shield the camera when the camera is required, thereby affecting photographing. In addition, compared with the buckle type locking, the magnetic component is not easy to wear, and stable adsorption can be maintained even after the magnetic component is used for multiple times. And the first magnetic attraction piece 31 can be connected with the second magnetic attraction piece 32 and the third magnetic attraction piece 33 in a selective magnetic attraction manner, so that the first magnetic attraction piece 31 can be used for maintaining the closed state and the first magnetic attraction piece 31 can be used for maintaining the open state, the better fixing effect of the lens cover 20 is realized, the structure is optimized, and the production cost and the difficulty are reduced.

It should be noted that, when the lens cover 20 is switched from the open state to the closed state, the lens cover 20 is pushed away from the positioning plate 112, at this time, the first magnetic attraction piece 31 and the second magnetic attraction piece 32 are separated, the first magnetic attraction piece 31 gradually approaches the third magnetic attraction piece 33 during the sliding process of the lens cover 20, and the adsorption effect between the third magnetic attraction piece 33 and the first magnetic attraction piece 31 can provide an auxiliary force when reaching a specific distance, so as to accelerate the closing of the lens cover 20. Conversely, when the lens cover 20 is switched from the closed state to the open state, the first magnetic attraction piece 31 gradually moves away from the third magnetic attraction piece 33 and approaches the second magnetic attraction piece 32, and the attraction effect between the second magnetic attraction piece 32 and the first magnetic attraction piece 31 can provide auxiliary force to accelerate the opening of the lens cover 20. The present embodiment thus provides a lens cover-attached protective case that is easier to operate than a snap-in locking scheme or other means of preventing slippage using a damping force.

Wherein, the first magnetic attraction piece 31, the second magnetic attraction piece 32 and the third magnetic attraction piece 33 may be magnets. Or the first magnetic attraction piece 31 is a magnet, and the second magnetic attraction piece 32 and the third magnetic attraction piece 33 are other magnetic attraction materials such as iron blocks. Alternatively, the second magnetic attraction member 32 and the third magnetic attraction member 33 may be magnets, and the first magnetic attraction member 31 may be a iron block or other magnetic attraction material, which is not limited in this embodiment.
