Disclosure of utility model

The technical scheme of the embodiment of the application is realized as follows:

In a first aspect, an embodiment of the present application provides an auxiliary device for an electronic apparatus, where the auxiliary device includes a first body and a second body. The second body can be arranged above the first body in a covering manner, the second body comprises a first supporting part, a second supporting part and a third supporting part, the first supporting part is rotationally connected with the first body, and two opposite ends of the second supporting part are respectively rotationally connected with the first supporting part and the third supporting part; the second body can form a first posture and a second posture relative to the first body; in the first posture, the second supporting part and the third supporting part meet the coplanar condition, and the second supporting part and the first supporting part have a first preset angle so that the electronic equipment borne by the second body has a first display view angle; in the second posture, the second supporting part and the first supporting part have a second preset angle, and the third supporting part and the second supporting part have a third preset angle, so that the electronic equipment borne by the second body has a second display view angle.

In the auxiliary device for the electronic equipment provided by the embodiment of the application, since the second body comprises the first supporting part, the second supporting part and the third supporting part, and the first supporting part is rotationally connected with the first body, and meanwhile, two opposite ends of the second supporting part are rotationally connected between the first supporting part and the third supporting part, for example, when the positions of the second supporting part and the third supporting part are fixed relative to the first supporting part, the second body can be in a certain pose when the first supporting part rotates relative to the first body; or when the position of the first supporting part relative to the first body is fixed, one or two of the second supporting part and the third supporting part can rotate relative to the first supporting part, so that the second body can be in various different postures, and the electronic equipment borne by the second body can have various display visual angles.

Specifically, the second body can form a first posture and a second posture with respect to the first body. In the first posture, the second supporting portion and the third supporting portion can meet the coplanar condition, namely the second supporting portion and the third supporting portion are equivalent to rotating to a first preset angle relative to the first supporting portion as a whole in a synchronous mode, and meanwhile the first supporting portion can rotate by a certain rotation angle relative to the first body, so that a first display view angle of the electronic equipment borne by the second body can be determined jointly by the rotation angle of the first supporting portion relative to the first body and the first preset angle. For example, when the rotation direction of the first support portion relative to the first body is consistent with the rotation direction of the second support portion relative to the first support portion, the sum of the rotation angle of the first support portion relative to the first body and the first preset angle can determine the first display viewing angle; or when the rotation direction of the first supporting part relative to the first body is opposite to the rotation direction of the second supporting part relative to the first supporting part, the first display view angle can be determined by the difference between the rotation angle of the first supporting part relative to the first body and the first preset angle.

Correspondingly, in the second posture, the second supporting part and the first supporting part have a second preset angle, the third supporting part and the second supporting part have a third preset angle, that is, the second supporting part and the third supporting part can not be coplanar, that is, on the basis that the first supporting part rotates relative to the first body, the second supporting part can rotate relative to the first supporting part, and the third supporting part can rotate relative to the second supporting part. For example, when the first supporting portion rotates to a certain rotation angle relative to the first body, the second supporting portion may rotate to a second preset angle relative to the first supporting portion, and the second supporting portion is kept at the second preset angle, and the third supporting portion may continue to rotate to a third preset angle relative to the second supporting portion, where the rotation directions of the first supporting portion, the second supporting portion, and the third supporting portion may be the same, or the rotation directions of the second supporting portion and the third supporting portion are opposite, and in particular, not limited, so that the rotation angle of the first supporting portion relative to the first body, the second preset angle, and the third preset angle together determine the second display viewing angle. The design can enable the second body to form various display view angles relative to the first body, so that the adaptability of the electronic equipment is improved.

In one possible implementation of the present application, in the first posture, the second support portion and the third support portion are coplanar to form a first support surface for the electronic device for supporting the electronic device in the first display view angle; the first display view angle is equal to the sum of the rotation angle of the first supporting part relative to the first body and a first preset angle.

In one possible implementation manner of the present application, in the second posture, the second supporting portion does not have a contact surface with the electronic device, and the third supporting portion is used for supporting the electronic device in the second display view angle; the second display view angle is determined by the rotation angle of the first supporting part relative to the first body, the second preset angle and the third preset angle.

In one possible implementation manner of the present application, the second body moves relative to the first body to form a third posture, and in the third posture, the first supporting portion, the second supporting portion and the third supporting portion are coplanar, so that the second body covers a surface of the electronic device opposite to the bearing surface.

In one possible implementation manner of the present application, a limiting structure is respectively disposed between the first supporting portion and the first body, between the second supporting portion and the first supporting portion, and between the second supporting portion and the third supporting portion, where the limiting structure is used for keeping the first supporting portion, the second supporting portion, and the third supporting portion in the first posture or the second posture.

In one possible implementation manner of the present application, the first body is a keyboard, and is capable of providing input instructions for the electronic device, and in the second posture, at least part of the electronic device is abutted against the outside of the key area on the operation side of the keyboard.

In one possible implementation of the application, in the second position, the front projection of the first support portion on the keyboard falls outside the key region on the keyboard when the first support portion is rotated to engage with the operation side of the keyboard.

In one possible implementation manner of the present application, the second supporting portion, the first supporting portion and the third supporting portion are all plate-shaped structures, and the size of the third supporting portion along the first direction is larger than the size of the first supporting portion and the second supporting portion along the first direction; the first direction is parallel to the plane of the plate-shaped structure and is perpendicular to the rotation axis direction of the electronic equipment.

In one possible implementation manner of the application, a magnetic attraction piece is arranged on one side, facing the electronic equipment, of the second supporting part, and in the first posture, the magnetic attraction piece is used for fixing the relative position of the second supporting part and the electronic equipment; when the first posture is switched to the second posture, the second supporting part and the electronic equipment can be separated from magnetic connection under the action of external force.

In a second aspect, an embodiment of the present application provides an electronic device system, including an electronic device and an auxiliary apparatus of the electronic device of any one of the first aspects.

In this embodiment, the type of the electronic device is not limited, and may be, for example, a notebook computer, a tablet computer, a mobile phone, a television, a computer all-in-one machine, or the like. In order to graphically illustrate the electronic device 2 provided in the embodiment of the present application, a tablet computer may be taken as an example of the electronic device.

Currently, with the development of diversified use requirements of electronic devices, the electronic devices are required to have multiple use states. The electronic equipment can be supported and fixed by the support auxiliary device so as to be in a required using posture. For example, the tablet computer can be supported and fixed in a fixed display state through the matched protective sleeve. Or the user needs to connect the tablet computer with the keyboard to perform the office mode, and only a single desktop office mode can be supported by the keyboard configuration bracket and the tablet combination, and a new bracket needs to be replaced when the user wants to switch to the drawing board mode and the display view angle mode in a larger range. Thereby limiting the application scenarios of the electronic device.

To this end, an embodiment of the present application provides an auxiliary device 1 of an electronic apparatus 2, and referring to fig. 1 to 3, the auxiliary device 1 includes a first body 11 and a second body 12. The second body 12 may be disposed above the first body 11, where the second body 12 includes a first supporting portion 121, a second supporting portion 122, and a third supporting portion 123, the first supporting portion 121 is rotationally connected with the first body 11, and two opposite ends of the second supporting portion 122 are respectively rotationally connected with the first supporting portion 121 and the third supporting portion 123; the second body 12 can form a first posture and a second posture with respect to the first body 11; in the first posture, the second supporting portion 122 and the third supporting portion 123 meet the coplanar condition, and the second supporting portion 122 and the first supporting portion 121 have a first preset angle θ1, so that the electronic device 2 borne by the second body 12 has a first display view angle; in the second posture, the second supporting portion 122 and the first supporting portion 121 have a second preset angle θ2, and the third supporting portion 123 and the second supporting portion 122 have a third preset angle θ3, so that the electronic device 2 carried by the second body 12 has a second display view angle.

The first body 11 in the embodiment of the present application is not limited, for example, the first body 11 may be a base for supporting the second body 12, or may be an accessory of the electronic device 2, for example, referring to fig. 2 and 3, and the first body 11 is a keyboard matched with the electronic device 2. In addition, the material of the second body 12 is not limited, and may be hard plastic, hard leather, glass fiber or carbon fiber board, alloy material, etc.; the second body 12 may be disposed over the first body 11, which may be understood as that when the second body 12 rotates relative to the first body 11 to be attached to the first body 11, that is, when the first supporting portion 121, the second supporting portion 122, and the third supporting portion 123 are coplanar and attached to the first body 11, the second body 12 covers over the first body 11. Here, the shape and size of the second body 12 are not limited, and it is preferable that the size of the second body 12 is identical to the size of the first body 11, so that the second body 12 just covers the first body 11 when the second body 12 is attached to the first body 11.

The relationship between the sizes of the first support portion 121, the second support portion 122, and the third support portion 123 constituting the second body 12 is not limited, and for example, the sizes of the first support portion 121, the second support portion 122, and the third support portion 123 may be the same, two of them may be the same, or all of them may be different. For a specific structure for realizing the rotational connection of the first supporting portion 121 and the first body 11, for example, two ends of the first body 11 along the rotation axis are respectively protruded with a rotation shaft, two ends of the first supporting portion 121 along the direction of the rotation axis are respectively provided with a hinge hole which is rotationally matched with the rotation shaft, and the rotation shaft of the first body 11 stretches into the hinge hole on the first supporting portion 121 to realize the relative rotation of the two; or the first body 11 and the first supporting part 121 are rotated relatively by a gear assembly; further alternatively, referring to fig. 4 and 5, taking as an example the rotating structure 14 for implementing the rotational connection between the second support portion 122 and the first support portion 121, the first support portion 121 has a first hinge member at two ends of the second support portion 122 opposite to the first support portion 121, the second support portion 122 has a second hinge member, and the first hinge member and the second hinge member have hinge holes respectively corresponding to each other, and the second support portion 122 is rotatably connected to the first support portion 121 by sequentially passing through the hinge holes of the first hinge member and the second hinge member through the hinge shaft. The rotating structure 14, in which two opposite ends of the second supporting portion 122 are respectively rotatably connected to the first supporting portion 121 and the third supporting portion 123, is not limited, and the rotating structure 14 for implementing the first supporting portion 121 and the first body 11 may be understood by referring to the description thereof will not be repeated here.

In the embodiment, since the second body 12 includes the first supporting portion 121, the second supporting portion 122 and the third supporting portion 123, and the first supporting portion 121 is rotatably connected to the first body 11, and two opposite ends of the second supporting portion 122 are rotatably connected between the first supporting portion 121 and the third supporting portion 123, for example, when the first supporting portion 121 rotates relative to the first body 11 under the condition that the positions of the second supporting portion 122 and the third supporting portion 123 are fixed relative to the first supporting portion 121, the second body 12 can be in a certain position; when the position of the first supporting portion 121 is fixed relative to the first body 11, one or both of the second supporting portion 122 and the third supporting portion 123 can be rotated relative to the first supporting portion 121, so that the second body 12 can be in a plurality of different postures, and the electronic device 2 carried by the second body 12 can have a plurality of display viewing angles.

Specifically, the second body 12 can form a first posture and a second posture with respect to the first body 11. In the first posture, referring to fig. 2, 6 and 7, the second supporting portion 122 and the third supporting portion 123 may satisfy the coplanar condition, that is, the second supporting portion 122 and the third supporting portion 123 are equivalent to being rotated to the first preset angle θ1 synchronously with respect to the first supporting portion 121, and simultaneously, the first supporting portion 121 may be rotated by a certain rotation angle with respect to the first body 11, so that the first display view angle of the electronic device 2 carried by the second body 12 may be determined by the rotation angle of the first supporting portion 121 with respect to the first body 11 and the first preset angle θ1. For example, when the rotation direction of the first support part 121 with respect to the first body 11 coincides with the rotation direction of the second support part 122 with respect to the first support part 121, the sum of the rotation angle of the first support part 121 with respect to the first body 11 and the first preset angle θ1 may determine the first display viewing angle; or when the rotation direction of the first supporting portion 121 relative to the first body 11 is opposite to the rotation direction of the second supporting portion 122 relative to the first supporting portion 121, the difference between the rotation angle of the first supporting portion 121 relative to the first body 11 and the first preset angle θ1 may determine the first display viewing angle.

Accordingly, in the second posture, referring to fig. 3, 8 and 9, the second supporting portion 122 and the first supporting portion 121 have a second preset angle θ2, the third supporting portion 123 and the second supporting portion 122 have a third preset angle θ3, that is, the second supporting portion 122 and the third supporting portion 123 may not be coplanar, while on the basis of the rotation of the first supporting portion 121 relative to the first body 11, the second supporting portion 122 may rotate relative to the first supporting portion 121, the third supporting portion 123 may rotate relative to the second supporting portion 122, for example, referring to fig. 7 and 8, when the first supporting portion 121 rotates to a certain rotation angle relative to the first body 11, the second supporting portion 122 may rotate to the second preset angle θ2 relative to the first supporting portion 121, such as on the basis of keeping the second supporting portion 122 at the second preset angle θ2, the third supporting portion 123 may continue to rotate to the third preset angle θ3 relative to the second supporting portion 122, wherein, the first supporting portion 121, the second supporting portion 122, the third supporting portion 123 may rotate to the same preset angle θ3, or the third supporting portion may not rotate to the third preset angle θ2 relative to the first body 11, and the third supporting portion may rotate to the third preset angle θ2, and the third supporting portion may not rotate to the first preset angle 11, or the third supporting portion may rotate to the third supporting portion 11. The above design can enable the second body 12 to form various display viewing angles relative to the first body 11, thereby improving the adaptability of the electronic device 2.

In some embodiments, referring to fig. 2, 6 and 7, in the first pose, the second support 122 is coplanar with the third support 123 forming a first support surface for the electronic device 2 for supporting the electronic device 2 in a first display view; the first display angle is equal to the sum of the rotation angle of the first supporting portion 121 with respect to the first body 11 and the first preset angle θ1. For example, referring to fig. 7, when the rotation direction of the first support part 121 relative to the first body 11 is consistent with the rotation direction of the second support part 122 relative to the first support part 121, for example, when the first support part 121 rotates counterclockwise, the rotation angle of the first support part 121 relative to the first body 11 may be 70 degrees, the first preset rotation angle of the second support part 122 relative to the first support part 121 may be 55 degrees, and the sum of the rotation angle of the first support part 121 relative to the first body 11 and the first preset angle θ1 may determine the first display viewing angle together, that is, the first display viewing angle is made to be a 125-degree operation mode, where the first display viewing angle is 125 degrees may be understood as a plane on which the display side of the electronic device 2 is located and the first body 11 or a plane on which the display side is located and the horizontal table is 125 degrees, that is also may be understood as a desktop office operation mode.

Here, it should be noted that the first display angle is not limited to a display angle of 125 degrees, for example, the first supporting portion 121 may also be rotated by 30 degrees, 45 degrees, 60 degrees, etc. with respect to the first body 11, and the second supporting portion 122 may be rotated by 25 degrees, 30 degrees, 45 degrees, etc. with respect to the first supporting portion 121, so that the first display angle has various display angle values, specifically, referring to fig. 4 and 5, a limiting structure 15 for limiting a rotation angle may be provided at a rotation connection portion of the first body 11 and the first supporting portion 121 and a rotation connection portion of the second supporting portion 122 and the first supporting portion 121, as needed, so that the electronic device 2 is maintained at the first display angle of 125 degrees, for example. In this way, the electronic device 2 can meet the required display viewing angle, so as to increase the application scenario of the electronic device 2.

In other embodiments, referring to fig. 3, 8 and 9, in the second posture, the second supporting portion 122 does not have a contact surface with the electronic device 2, and the third supporting portion 123 is used to support the electronic device 2 in the second display view angle; the second display viewing angle is determined by the rotation angle of the first supporting portion 121 with respect to the first body 11, the second preset angle θ2, and the third preset angle θ3.

For example, referring to fig. 7, 8 and 9, the first supporting portion 121 may be rotated counterclockwise by a certain rotation angle with respect to the first body 11, and then the electronic device 2 supported on the third supporting portion 123 is rotated counterclockwise by an external force, referring to fig. 8 and 9, the second supporting portion 122 is separated from the contact surface of the electronic device 2, and the second supporting portion 122 has a second preset angle θ2 with respect to the first supporting portion 121, and the third supporting portion 123 has a third preset angle θ3 with respect to the second supporting portion 122, and finally the first supporting portion 121 is closed clockwise to 0 degree, which may be understood by combining the change of the second body 12 from fig. 8 to 9, that is, the first supporting portion 121 is attached to the first body 11 at this time, that is, pulling back the electronic device 2 to a side close to the first body 11, and referring to fig. 9, the electronic device 2 may be placed in a second display view angle, such as the second display view angle is 155 degrees, where the 155 degrees of operation mode may be understood by considering that the display side of the electronic device 2 is placed in a plane or a horizontal plane in which is placed on the first plane or 155 degrees and the operation panel is understood by considering that the operation mode is understood by referring to fig. 155 degrees. In comparison with the 155-degree operation mode, the rotation angle of the second supporting portion 122 relative to the first supporting portion 121 or the angle of the third supporting portion 123 relative to the second supporting portion 122 can be rotated by 5 degrees, 10 degrees, 15 degrees, etc. counterclockwise or clockwise, and the second display viewing angle can be 140, 150 degrees, 160 degrees, etc. With the above design, since the first supporting portion 121 and the first body 11 and the second supporting portion 122 are rotatable relative to the first supporting portion 121 and the third supporting portion 123, any combination of display angles of the electronic device 2 can be realized, that is, the working angle of the electronic device 2 can be freely rotated and combined between 0 degree and 0-180 degrees, so that the electronic device 2 presents various display application scenes, and the adaptability of the electronic device 2 is greatly improved.

For example, referring to fig. 1, the second support portion 122, the first support portion 121, and the third support portion 123 are each plate-shaped structures, and the dimensions of the third support portion 123 in the first direction are each larger than the dimensions of the first support portion 121 and the second support portion 122 in the first direction; wherein the first direction is parallel to the plane of the plate-like structure and perpendicular to the rotation axis direction of the electronic device 2. Here, the second supporting portion 122, the first supporting portion 121, and the third supporting portion 123 of the plate-like structure are more convenient to be disposed in a surface-to-surface fit with the electronic device 2 than in a rod-like or block-like shape, and are convenient to provide a bearing surface with a larger contact area for the electronic device 2, and are more compact in structure. In addition, in consideration of whether the electronic device 2 is in the first display view or the second display view, in conjunction with fig. 6 to 9, the third supporting portion 123 is always abutted against the electronic device 2, that is, the third supporting portion 123 is always used as a bearing surface of the electronic device 2, it is obvious that when the third supporting portion 123 has a relatively large size, a more reliable supporting effect is provided to the electronic device 2, and therefore, it is preferable to design the size of the third supporting portion 123 in the first direction to be the largest compared to the first supporting portion 121 and the second supporting portion 122.

In some embodiments, referring to fig. 1, the movement of the second body 12 relative to the first body 11 can form a third posture, in which the first support 121, the second support 122, and the third support 123 are coplanar, so that the second body 12 covers a surface of the electronic device 2 opposite to the bearing surface. The above design can make the second body 12 have the function of the protective sleeve of the electronic equipment 2 on the one hand and make the whole auxiliary device 1 simpler and more compact on the other hand under the condition that the electronic equipment 2 does not need to work.

Further, in some embodiments, referring to fig. 4 and 5, between the first support portion 121 and the first body 11, between the second support portion 122 and the first support portion 121, between the second support portion 122 and the third support portion 123, a limiting structure 15 is respectively disposed, and the limiting structure 15 is used to maintain the first posture or the second posture between the first support portion 121, the second support portion 122, and the third support portion 123. The specific form of the limiting structure 15 is not limited, for example, taking the limiting structure 15 disposed between the first supporting portion 121 and the first body 11 as an example, the limiting structure 15 may include a limiting shaft and a limiting pin, the limiting shaft is used for being connected with the rotating shaft, the first preset angle θ1 of the first supporting portion 121 relative to the first body 11 may be designed in advance, when the rotating shaft rotates by an angle exceeding the first preset angle θ1, the limiting shaft may abut against the limiting pin, and further the limiting pin may prevent the rotating shaft from continuing to rotate, and the limiting pin may be made of a spring, a plastic or a steel material, so that the limiting shaft may be tightly fixed on the rotating shaft, where the limiting structure 15 may further be additionally provided with a damping structure, for example, a damping structure may be an elastic buffer member (rubber, an elastic sheet, etc.) sleeved at a free end of the rotating shaft and in friction contact with the first body 11 or the first supporting portion 121, so as to keep the first supporting portion 121, the second supporting portion 122, the third supporting portion 123 in the first posture or the second posture, and not to make the electronic device 2 fall down in the first display or the second display view angle.

For example, referring to fig. 2 and 3, the first body 11 is a keyboard capable of providing an input instruction to the electronic device 2, and in the second posture, referring to fig. 3, at least part of the electronic device 2 is abutted against the outside of the key area on the operation side of the keyboard. Here, the first body 11 is a design of a keyboard, and compared with the keyboard, the electronic device 2 and the bracket which are independently arranged, the keyboard and the second body 12 form an integral design, so that the structure is simple and compact, and the portable electronic device is convenient to carry; at the same time, the second body 12 for carrying the electronic device 2 can have the first posture or the second posture relative to the keyboard, so that the adaptability of the whole auxiliary device 1 can be increased. In addition, in the second posture, the design that at least part of the electronic device 2 is abutted against the outside of the key area on the keyboard operation side can enable the keyboard to share the supporting function of the second body 12 on the electronic device 2, so that the service cycle of the second body 12 can be increased, and the reliability of the auxiliary device 1 is further improved.

Continuing, referring to fig. 3, in the second posture, when the first support portion 121 is rotated to be engaged with the operation side of the keyboard, the orthographic projection of the first support portion 121 on the keyboard falls outside the key region on the keyboard. By the design, when the first supporting part 121 is attached to the operation side of the keyboard in the second posture, the first supporting part 121 interferes with the key area to influence the normal use of the keyboard.

Further, referring to fig. 4 and 5, a side of the second support portion 122 facing the electronic device 2 is provided with a magnetic attraction member 13, and in the first posture, the magnetic attraction member 13 is used for fixing a relative position of the second support portion 122 and the electronic device 2; when the first posture is switched to the second posture, the second supporting portion 122 and the electronic device 2 can be separated from the magnetic connection under the action of external force.

It should be noted that, the effect of the magnetic attraction piece 13 disposed on the side of the second support portion 122 facing the electronic device 2 can be understood by the effect of the magnetic attraction piece disposed in the protective case of the tablet computer in the related art, for example, the protective case of the tablet computer can be separated from the tablet computer by manually applying a small force. In this way, when the first posture is switched to the second posture, when the electronic device 2 is rotated under the action of external force, the second supporting portion 122 and the electronic device 2 can be separated from magnetic attraction connection by applying a small force, and accordingly, when the second supporting portion 122 and the electronic device 2 are required to be in magnetic attraction connection, the second supporting portion 122 can be gradually close to the electronic device 2, and the second supporting portion 122 and the electronic device 2 can be attached through the magnetic force of the magnetic attraction piece 13.

In addition, for example, referring to fig. 4 and 5, the first support portion 121 and the third support portion 123 are also provided with the magnetic attraction member 13 on the side facing the electronic apparatus 2. Here, taking the arrangement of the magnetic attraction member 13 on the third supporting portion 123 as an example, the electronic device 2 can be facilitated to be attached to the third supporting portion 123 more tightly, so that a reliable whole is formed between the third supporting portion 123 and the electronic device 2, thereby reducing the possibility that the electronic device 2 is separated from the third supporting portion 123, and meanwhile, the magnetic attraction connection mode can also facilitate the detachment of the electronic device 2 from the second body 12.
