First embodiment

Referring to fig. 1 and 2, the keypad sleeve 200 includes a base 100 and a cover 201. The base 100 includes a first base portion 10 and a second base portion 20. The first base unit 10 is provided with a keyboard 202. The second base portion 20 and the cover plate 201 are rotatably connected by a connecting portion 1001. The second base portion 20 is connected to the first base portion 10. And the second base part 20 and the first base part 10 can move relatively along the first direction X, so that the connecting part 1001 moves along the first direction X. The first direction X is a direction in which the connecting portion 1001 approaches or separates from the first base portion 10. The base 100 is extended or retracted to its original size in the first direction X by the relative movement of the first base portion 10 and the second base portion 20.

When the keyboard tray 200 is in the supporting state, the base 100 is extended in the first direction X, and the cover 201 and the electronic apparatus 300 are tilted with respect to the base 100. The second base part 20 and the first base part 10 move relatively in the first direction X, so that the base 100 is extended to provide a sufficient support area for supporting the cover plate 201, so that the electronic device 300 can be tilted by a set angle.

When the keyboard cover 200 is in the storage state, the second base portion 20 and the first base portion 10 move relatively along the first direction X, so that the base 100 retracts to the original size along the first direction X, and the cover plate 201 and the base 100 are covered. The chassis 100 is retracted to the original size, reducing the size of the supporting region in the first direction X and reducing the size of the keypad cover 200 in the stored state.

The keyboard 202 is a physical keyboard, but is not so limited. The physical keyboard comprises a plurality of pressable mobile keyboards. It is understood that in other embodiments, the keyboard 202 may be a touch keyboard, and the keyboard 202 is used by touch.

The first base portion 10, the second base portion 20, or the cover plate 201 may be made of the same or different materials, and are not limited herein as long as the second base portion 20 and the cover plate 201 can support the electronic device 300. The material may include an inner layer structure and an outer layer structure (not shown), wherein the inner layer structure is supported by a hard material, and the outer layer structure covers the inner layer structure and is made of a soft material. The inner layer structure made of hard materials can improve the strength of the keyboard cover 200 for supporting the electronic device 300, and the outer layer structure made of soft materials can improve the comfort level of the keyboard cover 200 and has a shockproof effect. The hard material can be plastic, metal and the like, and the soft material can be leather material, silica gel and the like.

It is understood that, in other embodiments, the first base portion 10, the second base portion 20, or the cover plate 201 may also be made of a single material.

The cover 201 includes a first cover portion 2011 and a second cover portion 2013. The first cover plate 2011 is rotatably connected to the second base portion 20 and the second cover plate 2013, respectively. The second cover part 2013 is used to fix the electronic apparatus 300. For example, the second cover portion 2013 is inserted outside the electronic device 300 or adhered to the electronic device 300, so that the second cover portion 2013 is fixed relative to the electronic device 300. When the keyboard tray 200 supports the electronic device 300, the first cover 2011 and the second base part 20 form a triangular ring structure, so that the base 100 and the cover 201 support the electronic device 300 together.

It is understood that in other embodiments, the second cover portion 2013 may be omitted, and the end of the first cover portion 2011 facing away from the second base portion 20 is directly supported on the electronic device 300.

The connecting portion 1001 may be a hinge structure (e.g., a hinge), a flexible hinge structure (e.g., a structure made of a flexible leather material, a cloth material, or the like), a pivoting mechanism, or the like that can achieve a rotatable connection. The connection portion 1001 connects the second base portion 20 and the first cover plate portion 2011 to be rotatable relative thereto.

The first cover 2011 and the second cover 2013 may be connected by a hinge, a flexible hinge, a pivot mechanism, or the like, so that the first cover 2011 and the second cover 2013 may rotate relatively.

The first base part 10 is further provided with a touch pad 203. The touch pad 203 is located on a side of the keyboard 202 away from the connecting portion 1001. The size of the supporting area on the base 100, which supports the electronic device 300 together with the cover plate 201, is variable, so that the base 100 is provided with the touch pad 203, the appearance size of the keyboard cover 200 does not need to be increased, and the user experience is improved.

For clarity of the following description, the second direction Y is defined as a thickness direction of the base 100, and the second direction Y is perpendicular to the first direction X, and the third direction Z is perpendicular to the first direction X and the second direction Y, respectively.

The second base portion 20 includes a telescopic structure that is telescopic in the first direction X. The telescopic structure can be extended or retracted to drive the connecting portion 1001 to move relative to the first base portion 10 along the first direction X.

The retractable structure may be a partial structure of the second base portion 20; the second base portion 20 is a stretchable structure as a whole.

The telescopic structure includes a plurality of telescopic units 21. The plurality of telescopic units 21 are rotatably connected in turn, and the plurality of telescopic units 21 can be stacked together or spread. Of the two telescopic units 21 located on both sides of the plurality of telescopic units 21, one telescopic unit 21 is connected to the first base part 10, and the other telescopic unit 21 is connected to the cover plate 201, so that the second base part 20 is connected to the first base part 10 and the cover plate 201, respectively.

The connection between the telescopic unit 21 and the first base part 10 may be a fixed connection or a rotatable connection. For example, the telescopic unit 21 and the first base portion 10 may be connected by a hinge, a flexible hinge, a pivoting mechanism, or the like.

When the keyboard cover 200 is in a supporting state, every two adjacent telescopic units 21 rotate and expand relatively, so that the base 100 is extended; when the keyboard cover 200 is in the storage state, the plurality of telescopic units 21 are sequentially stacked together, and the base 100 is retracted to the original size.

The stacking direction of the plurality of telescopic units 21 is parallel to the second direction Y. The number of the telescopic units 21 is an odd number greater than or equal to three, so that both sides of the second base part 20 can be respectively connected with the first base part 10 and the cover plate 201, and can be stacked together in the second direction Y.

The number of the telescopic units 21 is three, but is not limited thereto. For example, in other embodiments, the number of the telescopic units 21 may be five, as shown in fig. 3.

The telescopic unit 21 is fixed with the first base part 10, but is not limited thereto. For example, in other embodiments, the telescopic unit 21 and the first base portion 10 may also be rotatably connected.

The two telescopic units 21 and the telescopic unit 21 and the cover plate 201 can be connected through a hinge, a structure made of an easily deformable material, or a rotating shaft, so that the two telescopic units 21 can rotate relatively, and the telescopic unit 21 and the cover plate 201 can rotate relatively.

The stacking direction of the plurality of telescopic units 21 is parallel to the second direction Y, and when the keyboard cover 200 is in the storage state, the telescopic unit 21 fixedly connected to the first base part 10 and the cover plate 201 press the remaining telescopic units 21 in the middle, and the plurality of telescopic units 21 can be stably stacked together.

The plurality of telescopic units 21 have the same size, and adjacent two telescopic units 21 completely overlap, but not limited thereto. For example, in other embodiments, the sizes of the plurality of telescopic units 21 may be different, and two adjacent telescopic units 21 only partially overlap. The size of the second base unit 20 can be reduced as long as the plurality of telescopic units 21 are overlapped at least partially.

The total thickness of the plurality of telescopic units 21 stacked together is less than or equal to the thickness of the first base part 10, so that the cover plate 201 is flatly covered on the base 100; or in another embodiment, the total thickness of the plurality of telescopic units 21 stacked together is less than or equal to the thickness of the first base part 10, so that the cover plate 201 and the base 100 can cover opposite sides of the electronic device 300.

The thickness of the telescopic unit 21 connected to the first base part 10 is smaller than that of the first base part 10, so that the first base part 10 intersects with the telescopic unit 21 and forms a step surface 101, as shown in fig. 2. The electronic device 300 can be supported on the step surface 101, so that the base 100 can stably support the electronic device 300.

It is understood that, in other embodiments, the electronic device 300 may not contact the step surface 101, and the electronic device 300 is supported on the plane area of the telescopic unit 21 or the second base portion 20, and the electronic device 300 is stably tilted by a set angle by the friction force between the electronic device 300 and the plane area.

Second embodiment

Referring to fig. 4, a keyboard cover 200a of the second embodiment differs from the keyboard cover 200 of the first embodiment in that: the structure of the second base portion 20a of the keyboard cover 200a is different from the structure of the second base portion 20 of the keyboard cover 200.

The second base portion 20a includes a retractable structure. The telescopic structure includes a plurality of telescopic units 21a. The plurality of telescopic units 21a are sequentially rotatably connected, and the rotation directions of adjacent two telescopic units 21a are opposite, so that the plurality of telescopic units 21a can be sequentially stacked or unfolded. Of the two telescopic units 21a located on both sides of the plurality of telescopic units 21a, one telescopic unit 21a is connected to the first base part 10, and the other telescopic unit 21a is connected to the cover plate 201, so that the second base part 20a is connected to the first base part 10 and the cover plate 201, respectively. The stacking direction of the plurality of telescopic units 21a is parallel to the first direction X, so that the retraction of the second base portion 20a is simple and easy to operate, and only the first base portion 10 and the cover plate 201 need to be pushed to move towards each other.

The two telescopic units 21a and the telescopic unit 21a and the cover plate 201 can be connected by a hinge, a structure made of easily deformable material, or a rotating shaft, so that the two telescopic units 21a can rotate relatively, and the telescopic unit 21a and the cover plate 201 can rotate relatively.

The thickness of the telescopic unit 21a connected with the first base part 10 is smaller than that of the first base part 10, so that a step surface 101a is formed at the intersection of the first base part 10 and the telescopic unit 21a. The electronic device 300 can be supported on the step surface 101a, so that the base 100a can stably support the electronic device 300.

The first base part 10 is provided with a plurality of grooves 11, and the electronic device 300 can be supported against the groove walls of different grooves 11, so that the inclination angle of the electronic device 300 can be changed, and the user experience can be improved. It will be appreciated that in other embodiments, the recess 11 may be omitted.

When the keyboard cover 200a is in the storage state, each adjacent two of the telescopic units 21a may be overlapped and contacted, or may be in a V-shaped configuration without being contacted.

When the keyboard cover 200a is in the supporting state, the plurality of telescopic units 21a may be unfolded to form a plane, and the adjacent two telescopic units 21a may be unfolded only by a certain angle.

Third embodiment

Referring to fig. 5 and 6, a keymat 200b of the third embodiment differs from the keymat 200 of the first embodiment in that: the second base portion 20b of the keyboard cover 200b is different in structure from the second base portion 20 of the keyboard cover 200. The second base portion 20b includes a stretchable structure. The telescopic structure comprises a rod unit 22. The lever unit 22 is connected between the first base part 10 and the cover plate 201. The lever unit 22 can rotate relative to the first base portion 10, so that the size of the lever unit 22 along the first direction X is changed to drive the connecting portion 1001 of the cover plate 201 and the second base portion 20 to move along the first direction X.

The keypad cover 200b includes a first side 2001 and a second side 2002 in the third direction Z.

The second base portion 20b includes two rod units 22, but is not limited thereto. The rod unit 22 may be a rod or a plate made of metal, plastic, etc. The two rod units 22 are rotatably connected such that the two rod units 22 can be overlapped or unfolded in an X-shape. Both ends of each rod unit 22 are connected to the first base part 10 and the cover plate 201, respectively.

In order to prevent the rod unit 22 from twisting and generating shearing force to the first base portion 10/cover plate 201 when rotating, the rod unit 22 and the first base portion 10/cover plate 201 are connected by an elastic member 30. The elastic member 30 is shown by the dotted line in fig. 6, and the elastic member 30 may be a rubber band or a spiral coil made of plastic. The elastic member 30 is elastically deformable, and the elastic member 30 can be extended and contracted in any one of the first direction X, the second direction Y, and the third direction Z, so that the lever unit 22 and the first base unit 10/the cover plate 201 can be relatively rotated and moved.

The two rod units 22 have the same structure, and the rotation connecting shaft 221 of the two rod units 22 passes through the geometric center of each rod unit 22, so that the displacement of the four ends of the two rod units 22 is the same, and the four ends are respectively connected with the first base part 10 and the cover plate 201.

It is understood that in other embodiments, the structures of the two rod units 22 may be different as long as the displacements of the four ends of the two rod units 22 are the same when the two rod units 22 are rotated.

The two rod units 22 are overlapped when the base 100b is in the storage state, and two sides of at least one rod unit 22 are respectively contacted with the first base part 10 and the cover plate 201 to close the gap between the base 100b and the cover plate 201, so that the effect of covering the base 100b and the cover plate 201 to protect the electronic device 300 is improved.

It is understood that in other embodiments, the number of the rod units 22 may be plural.
