DETAILED DESCRIPTION

[0043] The preferred embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the preferred embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to make the present invention more thorough and complete, and to fully convey the scope of the present invention to those skilled in the art.

[0044] The existing leather case keyboard uses the following two methods to fix the tablet computer:

[0045] The first fixing method is to install a protective case on the leather case, and the protective case buckles and wraps the tablet computer. The protective case is fixedly connected to the leather case and cannot be removed, which makes it difficult to remove the tablet computer. At the same time, once the tablet computer is removed, it loses protection and is easily damaged by bumps and scratches.

[0046] The second fixing method is to set a positioning magnet in the leather case that corresponds to the magnet in the tablet computer to achieve magnetic fixation of the tablet computer. This magnetic fixation method has the problem that the tablet computer is easily displaced or loosened by external force. Because the greater the magnetic force, the thicker the magnet. If a magnet with a stronger magnetic force is used to improve the magnetic stability, it will not only increase the production cost, but also make the leather case keyboard thicker and heavier.

[0047] Example

[0048] In view of the above problems, this embodiment provides a leather case keyboard with a detachable protective cover. The protective cover and the supporting back plate are detachable, and the protective cover can be removed from the leather case together with the tablet computer.

[0049] like Figure 1-4 As shown, a leather keyboard with a detachable protective cover:

[0050] It includes a keyboard 100, a supporting back plate 200 and a protective shell 300, and the angle between the keyboard 100 and the supporting back plate 200 can be relatively adjusted;

[0051] The protective shell 300 is detachably connected to the supporting back plate 200 via a connecting piece;

[0052] The connector includes a first connector and a second connector that can be detachably connected, the first connector is arranged on the protective shell 300, and the second connector is arranged on the supporting back plate 200;

[0053] This design realizes the detachability of the protective shell 300 and the supporting back plate 200. Regardless of whether the keyboard 100 is used or not, the tablet computer can always be in a protected state, thereby reducing the probability of damage to the tablet computer.

[0054] When the keyboard 100 is in use, the protective shell 300 is connected to the support, and the various components of the leather case keyboard cooperate with each other to protect the tablet computer;

[0055] When the keyboard 100 is not in use, the protective cover 300 can be removed from the leather case together with the tablet computer. At this time, the protective cover 300 alone provides protection for the tablet computer.

[0056] In this embodiment, the protective shell 300 includes a base plate 310 , and the four corners of the base plate 310 are provided with fasteners 320 for buckling and wrapping the corners of the tablet computer;

[0057] The fastener 320 and the base plate 310 form a groove for accommodating and fixing the tablet computer.

[0058] In this embodiment, the connector is a magnetic member, the first connector and the second connector are both magnets, and the first connector and the second connector can be magnetically matched with each other, the first connector is embedded in the base plate 310, and the second connector is embedded in the supporting back plate 200. The design structure of embedded magnets is conducive to the lightweight design of the leather case keyboard.

[0059] It should be noted that, in addition to using magnets, the connector can also be selectively set according to specific needs. Exemplarily, the connector can be a snap-fitting member, the snap-fitting member includes a snap portion and a buckle portion, the side of the substrate 310 facing away from the embedding groove is provided with a plurality of snap portions, the buckle portion is provided on the supporting back plate 200, and the snap portions and the buckle portions are matched one by one.

[0060] In this embodiment, the support back plate 200 includes a fixed plate 210 and a folding support plate 220 that are rotatably connected. Specifically, the fixed plate 210 and the folding support plate 220 are connected via a hinge shaft 230. When in use, Figure 4As shown, the folding support plate 220 can be turned outward, so that the support back plate 200 is deformed into a bracket. At this time, the support seat of the folding support plate 220 is supported on the bearing surface of the leather case keyboard to support the tablet computer on the fixed plate 210;

[0061] In order to achieve a relatively adjustable angle between the keyboard 100 and the supporting back plate 200, the fixing plate 210 is connected to the keyboard 100 via the flexible sheet 520;

[0062] In order to ensure that the protective shell 300 and the supporting back plate 200 can form an effective connection, the second connecting body is at least arranged on the fixing plate 210 .

[0063] In this embodiment, a groove for mounting a magnet is provided at the bottom of the groove;

[0064] The groove bottom of the embedding groove is paved with a leather decoration layer 400 , the leather decoration layer 400 covers the groove bottom of the embedding groove, and the leather decoration layer 400 is bonded to the groove bottom of the embedding groove.

[0065] In this embodiment, the first connecting body includes a magnet group A330, and the second connecting body includes a magnet group B240. The magnet group B240 is disposed in the fixing plate 210, and the magnet group A330 and the magnet group B240 are magnetically matched.

[0066] In this embodiment, the first connector also includes a magnet group C340, and the second connector also includes a magnet group D250. The magnet group C340 is arranged in the folding support plate 220. The magnet group C340 and the magnet group D250 are magnetically matched. When the folding support plate 220 is not in use, the folding support plate 220 is fitted with the protective shell 300. Through the cooperation of the magnet group C340 and the magnet group D250, the folding support plate 220 can be restricted from swinging freely when not in use. It should be noted that the magnet group A330 is arranged on the long side of one side of the protective shell to correspond to the magnet group B240, and the magnet group C340 is arranged on the long side of the other side of the protective shell to correspond to the magnet group D250.

[0067] In this embodiment, an outer skin layer 500 is further included, and the outer skin layer 500 includes a first skin attachment portion 510 for wrapping the keyboard 100, a second skin attachment portion 530 for wrapping the support back plate 200, and a flexible sheet 520 for connecting the first skin attachment portion 510 and the second skin attachment portion;

[0068] The first leather-attached portion 510 is provided with holes for keys on the keyboard 100 to pass through.

[0069] In this embodiment, a tongue piece 540 extends outward from the side of the second leather attachment portion 530 away from the keyboard 100;

[0070] A magnet A is disposed inside the tongue piece 540 , and a magnet B is disposed inside the keyboard 100 at the end away from the tongue piece 540 . When the leather cover keyboard is closed, the magnet A can be magnetically connected with the magnet B to close the leather cover keyboard.

[0071] This design adopts a design structure with embedded magnets, which is conducive to the lightweight design of the leather keyboard. At the same time, in order to provide stable support when the tablet computer is used, the leather keyboard usually has a counterweight inside the keyboard 100 to prevent shaking or tipping. The shape and size of the counterweight need to be specifically designed in combination with the structural layout of the keyboard 100, which not only increases the complexity of the structure and the production cost, but also the built-in counterweight makes the overall thickness of the leather keyboard larger.

[0072] Based on the above problems, in order to further reduce the thickness of the keyboard 100, this embodiment also makes an improved design for the weight of the keyboard 100.

[0073] like Figure 5-7 As shown, in this embodiment, the bottom plate of the keyboard 100 is a self-weighted plate;

[0074] The self-weight plate comprises a plate body, and the plate body is composed of a first plate portion 110 and a second plate portion 120 connected in sequence;

[0075] The weight of the second plate portion 120 is greater than the weight of the first plate portion 110;

[0076] The second plate portion 120 is located at the end side of the keyboard 100 away from the supporting back plate 200;

[0077] The first plate portion 110 is a plastic part, and the second plate portion 120 is a metal part;

[0078] The first plate portion 110 and the second plate portion 120 are injection molded into one piece, thereby forming a plastic-metal composite structure, wherein the metal portion also has a counterweight function. In addition to the counterweight function, the metal portion can also increase the overall strength of the keyboard 100.

[0079] In this embodiment, a connection layer 111 extends from the bottom surface of the first plate portion 110 to the side where the second plate portion 120 is located;

[0080] The connecting layer 111 wraps the bottom surface of the second plate portion 120;

[0081] After the second plate portion 120 is manufactured, the second plate portion 120 is placed in an injection mold to inject the first plate portion 110 so that the first plate portion 110 and the second plate portion 120 form a plate body. The design of the connecting layer 111 can improve the connection strength between the first plate portion 110 and the second plate portion 120.

[0082] In this embodiment, the second plate portion 120 has an extended connection portion 121 , and the extended connection portion 121 is inserted into the first plate portion 110 . After connection, the second plate portion 120 and the connection end surface of the first plate portion 110 are in contact with each other.
