DETAILED DESCRIPTION
[0038] For better understanding of the above technical solutions, the technical solutions of the embodiments of the present application are described in detail below through the drawings and specific embodiments. It should be understood that the specific features in the embodiments of the present application and the specific features in the embodiments are detailed descriptions of the technical solutions of the embodiments of the present application, and are not limitations of the technical solutions of the present application. In the case of no conflict, the technical features in the embodiments of the present application and the embodiments can be combined with each other.
[0039] The present application considers that in the conventional technology, in order to enable the tablet computer to collect the desktop information of the user, that is, to enable the tablet computer to take a downward shot, three ways are mostly used, the first way is to add a mirror accessory at the front camera position: the form is mostly in the form of an accessory, the mirror is connected with the tablet computer through magnetic attraction or buckling, the mirror accessory is easy to lose and damage in use, and it is not convenient to store when not in use. A small number of products connect the mirror with the main machine by a rotating shaft and soft material to solve the problem of easy loss, but it will also cause the increase of the thickness of the whole machine and the loss of portability. The reflectivity of the current mirror surface reflecting material is up to 95%, so the mirror technology itself will also cause the decline of the camera quality. The manufacturing tolerance of the mirror accessory will cause the difference of the reflection angle of the product, resulting in the decline of the consistency of the product. The second way is to lift the front camera: it needs to realize the downward shot of fixed angle through the lifting of motor + rotating shaft, the product manufacturing cost is high, and the lifting mechanical structure is complex; in order to reduce the size of the lifting mechanism as much as possible, the material needs to be thin and small, resulting in the fragility of the product, which is easy to be knocked and fallen during use, resulting in high user return rate. The lifting camera scheme on the current market needs to thicken the learning tablet locally to accommodate the structure, resulting in that the learning tablet cannot be completely flat, and the reading and writing drawing operation experience in the flat scene is poor. The third way is to flip the camera: mostly protruding camera, which realizes the front camera and downward camera through the rotating shaft structure. The protruding camera cannot be effectively stored, and the portability is weak. The exposed rotating shaft structure is easy to be damaged when knocked and fallen.
