When the connecting arm 330 forms the maximum included angle with the bottom plate 100, the included angle formed between the supporting plate 200 and the bottom plate 100 is also larger than 180 degrees, at this time, the supporting plate 200 jacks up the first end of the bottom plate 100, and the first end of the bottom plate 100 is tilted up by a certain angle. Specifically, the larger the maximum included angle is, the higher the supporting plate 200 can lift the bottom plate when the cover plate 300 rotates to the second position, and the larger the tilting angle of the bottom plate is. Fig. 9 is a schematic side view of a support assembly when a cover plate is rotated to a second position according to an embodiment of the present disclosure. As shown in fig. 9, when the cover plate 300 is rotated to the second position, the connecting arm 330 forms a maximum included angle α with the base plate 100, and when the connecting arm 330 forms a maximum included angle with the base plate 100, the avoiding region can play a role of stably supporting the connecting arm 330. In the using process, when the cover plate 300 rotates to the second position, the support plate and the bottom plate 100 also form the maximum included angle α, and the bottom plate 100 can be jacked up by the support plate for a certain angle. When the supporting component that this application embodiment provided uses leather sheath keyboard, can set up the keyboard on the bottom plate 100, when apron 300 rotates to the second position, the keyboard can be to people's face one side slope, and is better with user's interactive experience, and whole structure still can keep better stability moreover.

Further, in an implementation manner, when the bottom plate 100 includes two fourth end surfaces 130, the number of the avoiding areas 160 is two, and the avoiding areas are respectively formed on the two fourth end surfaces 130 and are in mirror symmetry. In addition, the two avoidance zones 160 may also have different sizes, as long as any one of the avoidance zones 160 can limit the maximum included angle formed between the connecting arm 330 and the bottom plate 100, which is not specifically limited in the embodiment of the present application.

In other implementations, the number of avoidance zones 160 can also be only one, corresponding to the number of arc-shaped slots, second rotational axes, connecting arms, etc.

The embodiment of the application further provides a leather sheath keyboard, and fig. 10 is a schematic structural diagram of the leather sheath keyboard provided by the embodiment of the application. As shown in fig. 10, the leather sheath keyboard provided by the embodiment of the present application includes: a support assembly 10 and a keyboard 20. Wherein the keypad 20 is disposed on a side of the base plate 100 facing the cover plate 300.

The leather sheath keyboard that this application embodiment provided, when the apron is in the open mode, the backup pad is promoted to rotate to the position parallel with the bottom plate, can enlarge the whole support area in bottom, and make whole strong point move to the backup pad position from the bottom plate position after, thereby greatly improve the support stability, also be difficult for appearing rocking or the condition of empting when the great electronic equipment of collocation weight.

As shown in fig. 10, in one implementation, the cover panel 300 includes a first flap 340 and a second flap 350 disposed at an end of the first flap 340 distal from the extension 310. The second flap 350 is pivotally connected to the first flap 340 by the pivot assembly 30, and the second flap 350 is configured to be foldable about the first flap 340 from a fourth position to a fifth position. Wherein the second flap 350 is located at the fourth position and is located at the same plane as the first flap 340. In this embodiment, the fifth position can be set as required, and when the first folded plate 340 is completely opened and the second folded plate 350 is folded to the fifth position, the user can obtain higher comfort level. Like this, when the apron is in the open mode, there is the contained angle of rolling over between second folded plate and the first folded plate, can further increase user and the electronic equipment's of carrying transverse distance to and increase electronic equipment's mounting height, and can provide the electronic equipment who accords with user's demand more and present the angle, thereby improve the comfort level that the user used. In other implementation manners, the first flap 340 and the second flap 350 may also be integrally disposed and always located on the same plane, which is not limited in this application.

Furthermore, in one implementation, a magnetic part 360 may be disposed on the second flap 350, and the magnetic part 360 is configured to connect to an electronic device. Therefore, the electronic equipment is more convenient and faster to connect, and the user experience is improved. In addition, other ways of connecting the electronic device may also be adopted, for example, a clamping portion is provided on the second flap, and the connection way with the electronic device is not particularly limited in the embodiments of the present application.

In one implementation, the outer surfaces of the cover plate 300, the base plate 100, and the support plate 200 are coated with a leather protective layer 40. Specifically, the thickness of the cortical shell 40 is not limited in the embodiments of the present application as long as it can completely cover the outer surface of the entire structure. Thus, the leather protective layer can provide further protection, thereby prolonging the service life of the leather sleeve keyboard and also improving the impact resistance.
