1, 5 and 6, the present invention discloses a protection device for electronic equipment. When the protection device is combined with the electronic equipment, the protection device at least protects the area covered by the protection device on the electronic equipment; and the protection device can be combined with the electronic equipment separate. The electronic device can be a tablet computer or a mobile phone, etc. Wherein, the protective device includes a first plate 1; a second plate 2, the first plate 1 and the second plate 2 are turned over through a rotating connection 3; a limiting member, the limiting member is used to limit the first The flip angle of the board 1 relative to the second board 2 through the rotating connection member 3 .

Specifically, in one embodiment, as shown in FIG. 1 , the electronic device can be combined to the left side of the second board 2 , that is, the inner side, through a buckle/slot connection or magnetic adsorption. (referring to the left side of the second board 2 in FIG. 1 ), for example, the edge position of the second board 2 is provided with a card slot, and the edge part of the electronic device is embedded in the card slot to realize the connection with the second card slot. Combination of the board 2; or, a magnet is set on the second board 2, and the electronic device is combined with the second board 2 by being adsorbed on the magnet. When the angle between the first plate 1 and the second plate 2 is between 0° and 180°, the first plate 1 and the second plate 2 are maintained at any angle between 0° and 180° through the rotating connector, Support and protect electronic equipment. When the distance between the first plate 1 and the second plate 2 is 180°, the restriction works, that is, when the first plate 1 and the second plate 2 are on the same plane, it can pass through the slot or magnet set on the first plate 1 (preferably a magnet) to realize the combination of the electronic device on the inner side of the first board 1 (referring to the board surface facing the right side of the first board 1 in FIG. 1 ). Of course, because the protective device has a limiting member and the first board 1 and the second board 2 are located on the same plane when the restricting member works, at this time, the first board 1 may not be combined with the electronic equipment, and only the second board 1 may be kept. The combination of the board 2 and the electronic device can realize the protection of the back of the electronic device by the first board and the second board. Certainly, as shown in FIG. 1 , the protection device in another embodiment of the solution may further include a third board 19 rotatably connected to the second board 2 , and the third board is provided with keyboard input and touch input. When the electronic equipment is combined with the protective device, the first board 1 and the second board 2 on the same plane together with the combined electronic equipment are sent to the third board through the rotating connection between the second board 2 and the third board 19 19 rotations, the third plate 19 can cover the front of the electronic device (that is, the surface with display output area), the third plate 19 can also be fixedly connected with the first plate 1 and the second plate 2 by setting a fixing member, Thus, electronic equipment can be better protected.

In another embodiment, as shown in FIG. 5 , the electronic device can be combined on the inner side of the second board 2 through snap connection or magnetic adsorption. ° to 180°, the first plate 1 and the second plate 2 can be relatively maintained at any angle between 0° and 180°, and are supported on the support surface 20 to support the electronic components combined on the protection device. equipment. When there is 180° between the first plate 1 and the second plate 2, that is, when the first plate 1 and the second plate 2 are on the same plane, a draw-in groove or a magnet (preferably a magnet) can also be set on the first plate 1. The combination of electronic equipment to the inner side of the first board 1 is realized by way of suction), of course, because of the existence of the restricting piece, the first board may not be provided with any structure combined with the electronic equipment. At this time, the electronic equipment is combined with the first board 1 and the second board 2 respectively, and the electronic equipment combined with the protection device can be protected.

In another embodiment, the electronic device can be combined to the inner side of the first board 1 through buckle/slot connection or magnetic adsorption, and the angle between the first board 1 and the second board 2 is between 0° and 180°. When the angle is between, the second board 2 is flipped relative to the first board 1 and can be relatively maintained at any angle between 0° and 180°, so that the electronic equipment is supported on the supporting surface by the protection device. When the angle between the first plate 1 and the second plate 2 is 0°, that is, the first plate 1 and the second plate 2 are located on the same plane. The combination of the electronic device to the inner side of the second board 2 can be achieved by also setting a card slot or a magnet (preferably a magnetic attraction) on the second board 2. Of course, because of the existence of the restricting piece, the second board 2 can Do not set any structures combined with electronic equipment. At this time, the electronic equipment is combined with the first board 1 and the second board 2 respectively, and the electronic equipment combined with the protection device can be protected.

Wherein, the first plate 1 and the second plate 2 are overturned through the rotating connector 3. During the overturning process of the first plate 1 and the second plate 2, the limiting member can restrict the first plate 1 from rotating relative to the second plate 1 through the rotating connector 3. The inversion angle of the plate 2 is limited by limiting the inversion angle between the first plate 1 and the second plate 2, that is, the function of the restricting member is to limit inward inversion in any of the above-mentioned embodiments. And the first plate and the second plate are located in the same plane when the restricting member works. Moreover, when the first board 1 and the second board 2 are provided with a covering material, because the covering material is a complete piece of material with certain elasticity (for example, leather, braided fabric, etc.) and the covering material is integrally covered On the outer surface of the first plate 1, the outer surface of the second plate 2 and one side of the rotary joint 3 covering the first plate 1 and the second plate 2 (this side is the outer surface of the first plate 1 and the outer surface of the second plate 2) One side of the outer surface of the second plate 2). So, if the first panel 1 could be turned inwards and the presence of the swivel connection would tear the cladding material apart resulting in damage to the cladding material.

Further, referring to FIG. 1 , FIG. 6 and FIG. 7 , the restricting member is used to restrict the turning of the first board 1 relative to the second board 2 through the rotating joint 3 , that is, when the first board 1 and the second board 2 are located at the same in plane. The restricting member acts to restrict the continuous overturning of the first board 1 relative to the second board 2 beyond 180°. Thereby, the inward turning of the first plate is restricted.

Further, referring to FIG. 6 , in order to make the protective device overall beautiful, the protective device also includes a covering member 4, and the covering member 4 covers at least the outer surface of the first plate 1 and the outer surface of the second plate 2 to form a protective device of the outer surface. The material of the covering part 4 is generally flexible material. Because the covering material is a complete piece of material with certain elasticity (for example, leather, braiding, etc.) and the covering material is integrally covered on the outer surface of the first plate 1, the outer surface of the second plate 2 and the outer surface of the second plate 2 are covered. One side of the rotary connection between a plate 1 and a second plate 2 (this side is the side of the outer surface of the first plate 1 and the outer surface of the second plate 2). So, if the first panel 1 could be turned inwards and the presence of the swivel connection would tear the cladding material apart resulting in damage to the cladding material. So rely on the restraints to protect the wrapping 4 from being torn. Simultaneously because cladding part 4 is positioned at the side of rotary connector (this side is the side of the outer surface of first plate 1 and the outer surface of second plate 2) and is flexible so the outward turnover of protective device can not be affected. Wrapping has an effect.

The beneficial effect of the embodiment of the present invention is that: the protection device is located on the back of the electronic device; when the protection device is combined with the electronic device, no matter whether the user is in the support state or in the non-support state, the protection device is located on the back of the electronic device and faces the user. Electronic devices (tablets, phones, etc.) have no effect. In addition, during the overturning process of the first plate and the second plate, the limiting member can limit the inverting angle of the first plate relative to the second plate through the rotating connection, that is, the first plate is relative to the second plate under the action of the limiting member. The board can only be flipped out and not inward. Therefore, when the protection device is combined with the electronic equipment, the connection state of the combination of the protection device and the electronic equipment can be effectively protected. Because if the first board can be turned inward, it will destroy the connection state of the combination of the protection device and the electronic device, resulting in the unreasonable separation of the protection device and the electronic device (not the separation caused by the user's subjective separation intention); at the same time, After the protection device is separated from the electronic equipment, it is guaranteed that the first plate of the device can only be turned outwards relative to the second plate under the action of the limiting member, and cannot be turned inward, thereby effectively protecting the entire outer surface of the protection device. Material. Because the covering material is a complete piece of material with certain elasticity (for example, leather, braided fabric, etc.) One side of the rotary connection between the second plate and the second plate (this side is the outer surface of the first plate and the outer surface of the second plate). So, if the first panel were to be able to turn inwards and the presence of the swivel connection would tear the cladding material apart resulting in damage to the cladding material.
