[0033] The realization of the purpose, functional features and advantages of this application will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0034] In order to make the objectives, technical solutions and advantages of the present application clearer, the following part will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0035] When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. Instead, they are only examples of devices and methods consistent with some aspects of the present application as detailed in the attached claims.

[0036] In the description of the present application, it should be understood that the terms "first", "second", etc. are used for descriptive purposes only and should not be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present application can be understood according to the specific circumstances. In addition, in the description of the present application, unless otherwise specified, "multiple" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that three relationships may exist. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. The character " / " generally indicates that the objects associated before and after are in an "or" relationship.

[0037] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used in this specification are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0038] The tablet protective cover includes a back protective piece and a front protective piece. The back protective piece is used to connect with the back of the tablet, and the front protective piece is connected to the back protective piece. The front protective piece is movable relative to the tablet. When the front protective piece contacts the front of the tablet, the front of the tablet is shielded and there is no need to worry about damage to the front of the tablet. When the front protective piece is separated from the front of the tablet, the front of the tablet is exposed, which is convenient for users to view and operate.

[0039] In some tablet protective cases, when the front protective piece contacts the front of the tablet, the front protective piece and the back protective piece are only connected on one side. As a result, the front protective piece and the front of the tablet are easily separated, causing the front of the tablet to be exposed when the user does not need to use the tablet, increasing the risk of damaging the tablet.

[0040] Some other tablet protective covers have a connecting structure on the back protective piece. When the front protective piece contacts the front side of the tablet, the connecting structure connects to the front protective piece. In this way, the front protective piece and the back protective piece are connected on both sides, and the relative position between the front protective piece and the tablet is more stable.

[0041] However, the inventors have found that the connection structures in the prior art usually have built-in magnets, for example, the magnets are bonded to the connection structures, so the position of the magnets is prone to movement, the reliability is poor, and the risk of damage to several connections during use is high. Some connection structures are connected with buckle structures through threaded fasteners (such as screws and bolts), which affects the appearance and has a poor feel when used.

[0042] The tablet protective cover 1 in the embodiment of the present application can accommodate the first magnetic component 310 by providing a clamping member, and by fixing the clamping member to the connecting belt 300, the first magnetic component 310 can be fixed to the connecting belt 300, without the need for threaded fasteners for connection, and there is no need to bond the first magnetic component 310 to the connecting belt 300. The positioning effect between the first magnetic component 310 and the connecting belt 300 is good, the appearance is neater, and the reliability is greatly improved.

[0043] The tablet protective cover 1 according to an embodiment of the present application is described below with reference to the accompanying drawings.

[0044] See also Figure 1 , Figure 2 and Figure 5The tablet protective cover 1 of the embodiment of the present application includes a back protective member 100 , a front protective member 200 , a connecting belt 300 , a clamping member, a first magnetic member 310 and a second magnetic member 210 .

[0045] The back protective piece 100 is suitable for being connected to the back side of the tablet, the front protective piece 200 is rotatably connected to the back protective piece 100, the front protective piece 200 is used to shield the front side of the tablet, one of the back protective piece 100 and the front protective piece 200 is connected to the connecting belt 300, the clamping piece has a clamping space, a part of the connecting belt 300 is located in the clamping space and is clamped by the clamping piece, the first magnetic piece 310 is arranged in the clamping piece, the other of the back protective piece 100 and the front protective piece 200 is provided with a second magnetic piece 210, and the first magnetic piece 310 and the second magnetic piece 210 are magnetically attracted.

[0046] For example, the clamping member can be an integral member, and the first magnetic member 310 is installed in the clamping member. The first magnetic member 310 does not need to be built into the connecting belt 300. After the clamping member is formed, a force can be applied to the clamping member when it is connected to the connecting belt 300 to cause the clamping member to deform and clamp the connecting belt 300. Alternatively, the clamping member is a split structure, the first magnetic member 310 is stored in the split clamping member, and then the clamping member is installed on the connecting belt 300.

[0047] In addition, if Figure 3 and Figure 4 As shown, the back protection member 100 may be provided with a jacket 220 and a back support plate 140, and the jacket 220 and the back support plate 140 may be connected by a positioning glue 130, and the positioning glue 130 is located on the side of the thickness direction of the back support plate 140, and the back support plate 140 may be a lightweight plate, and the thickness of the back support plate 140 may be 0.9 mm to 1.1 mm, for example 0.9 mm, 1 mm, 1.1 mm, and the density of the back support plate 140 may be 0.8 g / cm3.

[0048] In addition, the front protective member 200 can be provided with a jacket 220 and a front support plate 230. The jacket 220 of the front protective member 200 and the jacket 220 of the back protective member 100 can be formed as one piece. The jacket 220 and the front support plate 230 can be connected by a positioning glue 130. The positioning glue 130 is located on the side of the thickness direction of the front support plate 230. The front support plate 230 can be a lightweight plate. The thickness of the front support plate 230 can be 0.9 mm to 1.1 mm, for example 0.9 mm, 1 mm, 1.1 mm, and the density of the front support plate 230 can be 0.8 g / cm3.

[0049] In this way, the front protection member 200 and the back protection member 100 have a simple structure and a small number of layers, which can reduce costs and reduce weight.

[0050] In addition, one of the first magnetic attraction member 310 and the second magnetic attraction member 210 is a magnetic material, such as a magnet, and the other can be a magnetic material, such as a magnet, or a material that can be attracted by magnets, such as metals such as iron.

[0051] According to the tablet protective cover 1 of the embodiment of the present application, by providing the back protective member 100, on the one hand, the tablet protective cover 1 can be connected and fixed to the back of the tablet, and on the other hand, the back of the tablet can be protected to reduce the probability of damage to the back of the tablet. In addition, the front protective member 200 can be used to shield the front of the tablet. When the tablet is not in use, the screen of the tablet can be protected by the front protective member 200 to reduce the probability of damage to the screen of the tablet. When the tablet is in use, the front protective member 200 is separated from the screen of the tablet so that the screen of the tablet can be observed and operated by the user.

[0052] In addition, the connecting belt 300 can be connected to the back protective member 100, the first magnetic member 310 is arranged on the connecting belt 300, and the second magnetic member 210 can be arranged on the front protective member 200. When the front protective member 200 blocks the front of the tablet, the first magnetic member 310 and the second magnetic member 210 can be magnetically attracted to fix the front protective member 200 and the back protective member 100 on opposite sides of the tablet, thereby preventing the front protective member 200 from being separated from the front of the tablet without human operation, thereby ensuring the protective effect of the front protective member 200 on the tablet.

[0053] Of course, it is understandable that in some embodiments of the present application, the connecting belt 300 can be connected to the front protection component 200 , and the second magnetic component 210 can be provided on the back protection component 100 .

[0054] The tablet protective cover 1 in the embodiment of the present application can accommodate the first magnetic component 310 by providing a clamping member, and by fixing the clamping member to the connecting belt 300, the first magnetic component 310 can be fixed to the connecting belt 300, without the need for threaded fasteners for connection, and there is no need to bond the first magnetic component 310 to the connecting belt 300. The positioning effect between the first magnetic component 310 and the connecting belt 300 is good, the appearance is neater, and the comfort and reliability of use are greatly improved.

[0055] like Figure 5-8 As shown, the clamping member may include a first cover plate 400 and a second cover plate 500, the first cover plate 400 and the second cover plate 500 are connected and jointly define a clamping space, the first cover plate 400 and the second cover plate 500 cooperate to clamp the connecting belt 300, and the first magnetic member 310 is located between the first cover plate 400 and the second cover plate 500, that is, the first magnetic member 310 is located in the clamping space.

[0056] By making the first cover plate 400 and the second cover plate 500 clamp the connecting belt 300 and the first magnetic member 310 from opposite sides of the connecting belt 300, the relative position between the connecting belt 300 and the first magnetic member 310 can be fixed, and the connecting belt 300 and the first magnetic member 310 do not need to be bonded or connected by threaded fasteners, and the connection stability is high. In addition, during the use of the tablet protective cover 1, since the connecting belt 300 needs to be repeatedly connected and separated from the front protective member 200, the end of the connecting belt 300 is prone to wear and tear. By shielding the surface of the connecting belt 300 with the first cover plate 400 and the second cover plate 500, the wear rate of the connecting belt 300 can be reduced, the service life of the connecting belt 300 can be extended, and the appearance is also neater.

[0057] The first cover plate 400 and the second cover plate 500 can be made of metal materials, so that the first cover plate 400 and the second cover plate 500 have a metal texture and a more beautiful appearance. In addition, there can be multiple first magnetic members 310, and the N poles of a part of the multiple first magnetic members 310 face the second magnetic member 210, and the S poles of another part of the multiple first magnetic members 310 face the second magnetic member 210. There are also multiple second magnetic members 210, and the multiple second magnetic members 210 correspond to the multiple first magnetic members 310 in a one-to-one magnetic attraction, so that the effect of precise positioning can be achieved.

[0058] Furthermore, when the front protective piece 200 blocks the flat screen, the connecting belt 300 is connected to the front protective piece 200 and the back protective piece 100 respectively. There can be a certain distance between the magnetic connecting belt 300 and the tablet. The electronic pen that communicates with the tablet is inserted between the connecting belt 300 and the tablet. The connecting belt 300 acts as a pen clip to prevent the electronic pen from being lost.

[0059] In this way, the tablet protective cover 1 according to the embodiment of the present application can not only fix the relative position between the front protective member 200 and the back protective member 100, but also ensure the relative position between the first magnetic member 310 and the connecting belt 300 is stable, and the reliability is further increased.

[0060] like Figure 2 and Figure 5 As shown, the first magnetic component 310 is passed through the connecting belt 300 along the thickness direction of the connecting belt 300, and at least one of the first cover plate 400 and the second cover plate 500 is provided with a positioning groove 410, that is, the first cover plate 400 is provided with a positioning groove 410, or the second cover plate 500 is provided with a positioning groove 410, or the first cover plate 400 and the second cover plate 500 are both provided with a positioning groove 410, and a part of the first magnetic component 310 is provided in the positioning groove 410.

[0061] In this way, the relative position between the first magnetic member 310 and the connecting belt 300 is determined, which can improve the installation accuracy. In addition, when the first cover plate 400 and the second cover plate 500 are both provided with positioning grooves 410, the first magnetic member 310 is inserted into the two positioning grooves 410, and the relative position between the first magnetic member 310, the first cover plate 400 and the second cover plate 500 is determined, which can further improve the installation accuracy.

[0062] By setting the positioning groove 410, on the one hand, the volume of the first cover plate 400 and the second cover plate 500 can be reduced, material can be saved and cost can be reduced. On the other hand, the thickness of the first cover plate 400 and the thickness of the second cover plate 500 in the corresponding area of ​​the first magnetic component 310 can be thinned, so that the distance between the first magnetic component 310 and the second magnetic component 210 is smaller, which is beneficial to increase the magnetic force between the first magnetic component 310 and the second magnetic component 210, and the fixing effect is better when the front protection component 200 is buckled on the front of the tablet.

[0063] like Figure 6-Figure 8 As shown, one of the first cover plate 400 and the second cover plate 500 is provided with a first connection portion 420 and the other is provided with a second connection portion 510, at least one of the first connection portion 420 and the second connection portion 510 is penetrated in the connecting belt 300 along the thickness direction of the connecting belt 300, and the first connection portion 420 and the second connection portion 510 are connected.

[0064] By providing the first connection portion 420 and the second connection portion 510, the connection between the first cover plate 400 and the second cover plate 500 can be achieved, and the relative position between the first cover plate 400 and the second cover plate 500 can be fixed. In addition, since at least one of the first connection portion 420 and the second connection portion 510 passes through the connecting belt 300, the relative position stability between the first cover plate 400, the second cover plate 500 and the connecting belt 300 can be improved, and the probability of separation of the connecting belt 300, the first cover plate 400 and the second cover plate 500 can be reduced.

[0065] like Figure 6-Figure 8 As shown, there are two first connection parts 420, and the two first connection parts 420 are located on opposite sides of the first magnetic member 310 in the width direction of the connection belt 300. There are two second connection parts 510, and the two second connection parts 510 are located on opposite sides of the first magnetic member 310 in the width direction of the connection belt 300. The two first connection parts 420 and the two second connection parts 510 are connected one by one.

[0066] In this way, the first cover plate 400 and the second cover plate 500 are connected at multiple points, which further improves the connection strength between the first cover plate 400 and the second cover plate 500, and can avoid rotation between the connecting belt 300, the first cover plate 400 and the second cover plate 500, making the relative position more stable.

[0067] In addition, the two first connecting parts 420 are located on opposite sides of the first magnetic component 310 in the width direction of the connecting belt 300, and the two second connecting parts 510 are located on opposite sides of the first magnetic component 310 in the width direction of the connecting belt 300. The first cover plate 400 and the second cover plate 500 apply pressure to the first magnetic component 310 from opposite sides of the first magnetic component 310, so that the force on the first magnetic component 310 is more uniform, and the first magnetic component 310 is better clamped.

[0068] like Figure 6-Figure 8 As shown, the above-mentioned first connecting part 420 includes an annular column 421, and the second connecting part 510 is inserted into the annular column 421. One of the inner circumference of the annular column 421 and the outer circumference of the second connecting part 510 is provided with an inserting hole 422 and the other is provided with an inserting protrusion 511, and the inserting protrusion 511 is inserted into the inserting hole 422.

[0069] Specifically, the second connection portion 510 can be set to a columnar shape, and through the cooperation of the plug hole 422 and the plug protrusion 511, the connection strength between the first cover plate 400 and the second cover plate 500 can be improved, so that the connection between the first cover plate 400 and the second cover plate 500 is more stable.

[0070] like Figure 6-Figure 8 As shown, there are two plug-in holes 422, which are arranged on opposite radial sides of the annular column 421; the second connecting portion 510 includes two arc columns 512, which are spaced apart in the circumferential direction of the second connecting portion 510, and an inserting protrusion 511 is provided on the outer peripheral surface of each arc column 512, and the two inserting protrusions 511 are inserted into the two plug-in holes 422 one by one.

[0071] By using the plug-in holes 422 to cooperate with the plug-in protrusions 511 on both radially opposite sides of the annular column 421, the connection force between the first cover plate 400 and the second cover plate 500 is more evenly distributed, avoiding deflection between the first cover plate 400 and the second cover plate 500, or damage due to stress concentration.

[0072] In addition, since the two arc columns 512 are arranged at intervals, the hardness of each arc column 512 is reduced and it is more susceptible to deformation, and there is sufficient space between the two arc columns 512 for the arc columns 512 to deform and move. While ensuring the connection strength, the convenience of plugging and unplugging between the annular column 421 and the second connecting part 510 is improved.

[0073] like Figure 5-Figure 8 As shown, the first connection portion 420 further includes a central column 423 , an annular column 421 is disposed around the central column 423 , the central column 423 is inserted into the second connection portion 510 , and an arc column 512 is disposed between the central column 423 and the annular column 421 .

[0074] In this way, the contact area between the first connecting part 420 and the second connecting part 510 is larger, the positioning effect is more secure, and the central column 423 can support the arc column 512, and the arc column 512 is deformed by mistake and causes the plug-in protrusion 511 to separate from the plug-in hole 422, thereby ensuring the connection reliability between the first connecting part 420 and the second connecting part 510.

[0075] like Figure 6-Figure 8 As shown, the central column 423 is beyond the annular column 421, and the bottom wall of the second connecting portion 510 is provided with a groove 513, and the central column 423 is inserted into the groove 513. In this way, the central column 423 contacts the second connecting portion 510 before the annular column 421, so that a pre-positioning can be formed between the central column 423 and the second connecting portion 510, reducing the difficulty of positioning between the second connecting portion 510 and the arc column 512.

[0076] A groove 513 is provided on the bottom wall of the second connecting part 510 to accommodate the central column 423, thereby preventing the second connecting part 510 from being unable to be inserted into the bottom of the annular column 421, so that the plug-in protrusion 511 can be inserted into the plug-in hole 422, thereby improving the assembly accuracy.

[0077] like Figure 6 and Figure 8 As shown, the diameter of the central column 423 gradually decreases toward the second connecting portion 510 .

[0078] Specifically, one end of the center column 423 close to the second connection part 510 can be constructed as a truncated cone, and the one end of the center column 423 close to the second connection part 510 can play a guiding role, and the cross-sectional area of ​​the one end of the center column 423 close to the second connection part 510 is the smallest.

[0079] In this way, it is convenient to insert the center column 423 into the second connection portion 510 , and the process of inserting the center column 423 into the second connection portion 510 is smoother, thereby improving assembly efficiency.

[0080] like Figure 6 and Figure 7 As shown, the inner diameter of the second connection portion 510 gradually increases toward the direction approaching the first connection portion 420 .

[0081] Specifically, one end of the second connection portion 510 close to the center column 423 can play a guiding role, and the cross-sectional area of ​​one end of the second connection portion 510 close to the second connection portion 510 is the largest.

[0082] In this way, it is convenient to insert the center column 423 into the second connection portion 510 , and the process of inserting the center column 423 into the second connection portion 510 is smoother, thereby improving assembly efficiency.

[0083] like Figure 6-Figure 8 As shown, the plug hole 422 is disposed at one end of the annular column 421 facing away from the second connection portion 510 , and the plug protrusion 511 is disposed at one end of the second connection portion 510 facing the annular column 421 .

[0084] In this way, when the second connecting part 510 is inserted into the bottom of the annular column 421, the plug-in protrusion 511 can be inserted into the plug-in hole 422, and the contact area between the second connecting part 510 and the annular column 421 is larger, which is beneficial to avoid shaking between the first cover plate 400 and the second cover plate 500. The connection strength between the first cover plate 400 and the second cover plate 500 is higher, and the relative position between the first cover plate 400 and the second cover plate 500 is more stable.

[0085] like Figure 6 and Figure 7 As shown, the above-mentioned plug-in protrusion 511 is provided on the second connecting portion 510 , and the size of the plug-in protrusion 511 in the radial direction of the annular column 421 gradually decreases in the direction away from the annular column 421 .

[0086] Specifically, the side surface of the plug-in protrusion 511 away from the second connecting portion 510 can be a plane or a curved surface, and the plug-in protrusion 511 can play a guiding role. The cross-sectional area of ​​the plug-in protrusion 511 gradually increases in the direction away from the annular column 421, that is, the cross-sectional area of ​​the end of the plug-in protrusion 511 close to the annular column 421 is the smallest.

[0087] In this way, it is convenient to insert the second connection part 510 into the annular column 421 , and the process of inserting the second connection part 510 into the annular column 421 is smoother, thereby improving assembly efficiency.

[0088] like Figure 5-Figure 8 As shown, the second cover plate 500 is provided with a folded edge 520, and the folded edge 520 extends in the direction of. The first cover plate 400 is provided with a first avoidance notch 430, the connecting belt 300 is provided with a second avoidance notch 320, and the folded edge 520 is inserted into the first avoidance notch 430 and the second avoidance notch 320.

[0089] By providing the folded edge 520, on the one hand, part of the outer peripheral surface of the connecting belt 300 can be shielded to reduce the probability of damage to the connecting belt 300, and on the other hand, the connection area between the first cover plate 400 and the second cover plate 500 is increased, and the connection strength between the first cover plate 400 and the second cover plate 500 is improved, and the relative position between the first cover plate 400 and the second cover plate 500 is more stable.

[0090] By providing the first avoidance notch 430 and the second avoidance notch 320, on the one hand, the volume of the second cover plate 500 and the volume of the connecting belt 300 are reduced, saving materials and thus reducing costs; on the other hand, the relative positions of the first cover plate 400, the connecting belt 300 and the second cover plate 500 can be fixed.

[0091] When the first magnetic member 310 and the second magnetic member 210 are magnetically attracted, the second cover plate 500 is located at a side of the connecting belt 300 that is away from the front protection member 200 .

[0092] like Figure 5-Figure 8 As shown, the above-mentioned folded edge 520 includes a first folded edge 521 and a second folded edge 522. The first folded edge 521 is located at the above-mentioned other end of the connecting belt 300, and the second folded edge 522 is located on both sides of the width direction of the connecting belt 300. The second folded edge 522 is connected to the first folded edge 521.

[0093] That is to say, the first folded edge 521 covers the end face of the connecting belt 300, and the second folded edge 522 covers the opposite side faces in the width direction of the other end of the connecting belt 300. The first cover plate 400, the second cover plate 500, the first folded edge 521 and the second folded edge 522 together form a closed space, and then cover the above-mentioned other end of the connecting belt 300.

[0094] In this way, on the one hand, the protection range of the connection belt 300 is larger, which can reduce the probability of damage to the connection belt 300. On the other hand, the area where the first cover plate 400 and the second cover plate 500 are connected by the folding edge 520 is larger, the connection strength between the first cover plate 400 and the second cover plate 500 is improved, and the relative position is more stable. In addition, the appearance is also more neat, and it has a metallic texture, which makes the user more comfortable.

[0095] like Figure 2 As shown, at least three of the top corners of the above-mentioned back protection member 100 are provided with corner magnetic members 110, at least three corner magnetic members 110 are asymmetrically arranged with respect to the center line of the length direction of the tablet, and / or at least three corner magnetic members 110 are asymmetrically arranged with respect to the center line of the width direction of the tablet.

[0096] That is to say, the corner magnetic member 110 is asymmetrically arranged with respect to the center line of the length direction of the tablet, or the corner magnetic member 110 is asymmetrically arranged with respect to the center line of the width direction of the tablet, or the corner magnetic member 110 is asymmetrically arranged with respect to the center line of the length direction of the tablet, and is asymmetrically arranged with respect to the center line of the length direction of the tablet.

[0097] It should be noted that the corner magnetic attraction member 110 may be a structure such as metal that can be magnetically attracted by a magnet, or the corner magnetic attraction member 110 may be a structure such as a magnet that has magnetic properties.

[0098] Specifically, the tablet is provided with a magnetic structure that cooperates with the corner magnetic attraction piece 110, which can realize the positioning between the back of the tablet and the back protection piece 100 and improve the connection strength. In addition, due to the asymmetrical distribution of the corner magnetic attraction piece 110, a foolproofing can be formed between the tablet and the tablet protection cover 1, avoiding the wrong installation direction and improving the installation accuracy.

[0099] like Figure 2 As shown, the back protection member 100 is provided with at least three positioning magnetic members 120, and the at least three positioning magnetic members 120 are arranged at intervals along the length direction of the back protection member 100, and the positioning magnetic members 120 are close to the front protection member 200 in the width direction of the back protection member 100. In other words, one side of the back protection member 100 in the width direction is connected to the front protection member 200, and the distance between the positioning magnetic member 120 and the one side of the back protection member 100 in the width direction is smaller than the distance between the positioning magnetic member 120 and the other side of the back protection member 100 in the width direction.

[0100] It should be noted that the positioning magnetic attraction member 120 may be a structure such as metal that can be magnetically attracted by a magnet, or the positioning magnetic attraction member 120 may be a structure such as a magnet that has magnetic properties.

[0101] Specifically, the tablet is provided with a magnetic structure that cooperates with the positioning magnetic suction piece 120, which can realize the positioning between the back of the tablet and the back protection piece 100, and improve the positioning accuracy and connection strength. In addition, the number of the positioning magnetic suction pieces 120 is not less than three, and the plurality of positioning magnetic suction pieces 120 are asymmetrically arranged about the center line of the width direction of the tablet, which limits the relative position between the tablet and the back protection piece 100 in the width direction and the length direction of the back protection piece 100, so that the tablet and the tablet protection cover 1 can be foolproof.

[0102] For example, Fig. 9 As shown, each positioning magnetic member 120 may include two sub-positioning magnetic members 121, with the N pole of one sub-positioning magnetic member 121 facing the tablet, and the S pole of the other positioning magnetic member 121 facing the tablet, further improving the positioning accuracy between the tablet and the tablet protective cover 1.

[0103] The two sub-positioning magnetic components 121 can be installed on the same shell 122, and then the shell 122 is installed on the back protective component 100, so as to reduce the difficulty of installation. The relative positions of the two sub-positioning magnetic components 121 are limited by the shell 122, and the relative positions of the two sub-positioning magnetic components 121 are not easy to occur, so as to ensure the positioning accuracy.

[0104] like Figure 2As shown, the front protection member 200 is provided with an inductive magnetic member 231. When the distance between the front protection member 200 and the front of the tablet is less than a preset value, the tablet can detect the inductive magnetic member 231, so that the screen of the tablet can be turned off.
