Description

Technical Field

[0001] This application relates to the technical field of electronic device accessories, and more particularly to an electronic device protective case and electronic device kit. Background Technology

[0002] Tablet cases effectively protect tablets from scratches, bumps, and drops during daily use. Currently, most tablet cases include a stand function. This stand allows the tablet to be stably supported on a table without being held by hand, enabling users to perform other two-handed activities, such as typing, while viewing the tablet. Summary of the Invention

[0003] This application provides an electronic device protective case and electronic device kit, which aims to solve the problem that the electronic device display screen is positioned too low when using an electronic device protective case to support the electronic device. The electronic device protective case can raise the display screen of the electronic device, thereby improving the user's viewing experience.

[0004] To achieve the above objectives, the embodiments of this application adopt the following technical solutions:

[0005] In a first aspect, embodiments of this application provide a protective case for an electronic device. The protective case includes a rotating connecting portion, a first plate portion, and a second plate portion. The first plate portion is connected to the rotating connecting portion. The second plate portion is used to fix an electronic device, such as a tablet computer. The second plate portion is rotatably connected to the rotating connecting portion about a rotation axis. In a first state, the bottom surface of the first plate portion is used to support a support surface, and the second plate portion rotates to a position where its top reference surface faces away from the bottom plate reference surface, forming an angle with the first plate portion. The top reference surface passes through the rotating connecting portion at the position furthest from the bottom plate reference surface in a first direction and is parallel to the bottom plate reference surface. The first direction is the direction perpendicular to the bottom plate reference surface in the first state (i.e., the thickness direction of the first plate portion in the first state), and the bottom plate reference surface is the plane containing the bottom surface of the first plate portion.

[0006] In related technologies, when the electronic device protective case is in a first state, a portion of the second plate is located on the side where the top reference surface faces the bottom reference surface. In this embodiment, when the electronic device protective case is in its first state, the entire second plate rotates to the side where the top reference surface faces away from the bottom reference surface. When the electronic device protective case is in its first state, the connecting portion in this embodiment is further away from the bottom reference surface than the second plate in related technologies, meaning the second plate is positioned higher. As an example of the second plate being raised, a gap exists between the second plate and the top reference surface.

[0007] With the electronic device protective case in its first state, the electronic device, fixed to the second plate, is also raised to a higher position due to the higher position of the second plate. As the electronic device is raised, its display screen is also raised, providing the user with a more comfortable viewing experience.

[0008] As a non-limiting embodiment, the first plate includes a user input area configured for a user to provide information input to the electronic device. The second plate includes a first rotating plate and a second rotating plate that are rotatably connected. In a first state, the first rotating plate and the first plate have a first angle, and the second rotating plate and the first plate have a second angle, the second angle being greater than the first angle, so that the electronic device extends toward the user input area while the second rotating plate is fixed.

[0009] In this embodiment, the second angle is greater than the first angle, allowing the electronic device, with the second rotating plate fixed, to display the screen at a relatively tilted angle, providing the user with a better viewing angle. Simultaneously, the second angle is greater than the first angle, causing the electronic device, with the second rotating plate fixed, to extend closer to the user input area, thus bringing it closer to the user input area. Users face the risk of their hands being obstructed by the electronic device when operating the user input area; conversely, the screen can easily be obstructed by hands, affecting the viewing experience. In this embodiment, as the electronic device is raised, it moves further away from the user input area in a direction perpendicular to it. This reduces both the risk of the user's hands being obstructed and the risk of the screen being obstructed by hands, thereby improving the user's viewing experience.

[0010] As a non-limiting embodiment, the second plate portion includes a connecting portion disposed at one end of the second plate portion facing the rotating connecting portion, and the connecting portion is rotatably connected to the rotating connecting portion. The radius of rotation of the connecting portion about the rotation axis is greater than the distance from the rotation axis to the top reference surface.

[0011] In this embodiment, when the radius of rotation of the connecting portion about the rotation axis is greater than the distance from the rotation axis to the top reference surface, the connecting portion can rotate to the side of the top reference surface facing away from the rotation axis without being blocked by the rotating connecting portion. Since the connecting portion can represent the end of the second plate portion facing the rotating connecting portion, that is, the part of the second plate portion closest to the rotating connecting portion, when the connecting portion can rotate to the side of the top reference surface facing away from the bottom plate reference surface, it means that the part of the second plate portion closest to the rotating connecting portion and other more distant parts can rotate to the side of the top reference surface facing away from the rotation axis, thereby achieving the purpose of raising the electronic device.

[0012] As a non-limiting embodiment, the electronic device protective case also includes an arcuate portion. A connecting portion is fixedly connected to the arcuate connecting end of the arcuate portion, and the arcuate portion is rotatably connected to the rotating connecting portion about the rotation axis. The radius of the arcuate portion is greater than the distance from the rotation axis to the top reference surface, so that the rotation radius of the connecting portion is greater than the distance from the rotation axis to the top reference surface. The radius of the arcuate portion is the distance from the rotation axis to the arcuate connecting end.

[0013] In this embodiment, the arc-shaped connecting end is one end of the arc-shaped portion in the circumferential direction. Since the connecting portion is fixedly connected to the arc-shaped connecting end of the arc-shaped portion, and the arc-shaped portion has its center line around the rotation axis, the radius of rotation of the connecting portion around the rotation axis is approximately equal to the radius of the arc-shaped portion. The radius of the arc-shaped portion is approximately the distance from the rotation axis to the arc-shaped connecting end. When the radius of rotation of the connecting portion is approximately equal to the radius of the arc-shaped portion, the radius of rotation of the arc-shaped portion can be controlled to control the radius of rotation of the connecting portion. This embodiment makes the radius of the arc-shaped portion greater than the distance from the rotation axis to the top reference surface, and makes the radius of rotation of the connecting portion greater than the distance from the rotation axis to the top reference surface, thereby achieving the purpose of raising the electronic device.

[0014] As a non-limiting embodiment, the distance from the rotation axis to the bottom plate reference surface is greater than the distance from the rotation axis to the top reference surface.

[0015] This embodiment provides another specific implementation where the connecting part can be rotated to the side of the top reference surface facing away from the rotation axis, that is, the distance from the rotation axis to the bottom plate reference surface is greater than the distance from the rotation axis to the top reference surface.

[0016] In related technologies, the distance from the rotation axis to the bottom reference surface is equal to the distance from the rotation axis to the top reference surface. In this embodiment, the distance from the rotation axis to the bottom reference surface is greater than the distance from the rotation axis to the top reference surface, which is equivalent to raising the position of the rotation axis, thereby raising the position of the connecting part in the first direction, and thus achieving the purpose of raising the display screen of the electronic device.

[0017] As a non-limiting embodiment, the rotating connection includes a receiving cavity having a top surface and a bottom surface facing away from each other in a first direction, the top surface of the receiving cavity being closer to the top extension surface than the bottom surface. The receiving cavity has an opening. The electronic device protective sleeve also includes a pivot bracket, a pivot, and a fixing part. The pivot bracket is fixed inside the receiving cavity and has a supporting end. The pivot is rotatably disposed on the supporting end, and the axis of rotation is the axis of the pivot. The fixing part fixes the pivot and the arcuate portion respectively. A portion of the arcuate portion is located inside the receiving cavity, and a portion of the arcuate portion including the arcuate connecting end extends through the opening to the outside of the receiving cavity, so that the arcuate connecting end is fixedly connected to the connecting part. The distance from the supporting end to the top surface of the receiving cavity is less than the distance from the supporting end to the bottom surface of the receiving cavity.

[0018] This embodiment provides a specific implementation scheme for raising the position of the rotation axis, that is, achieving the purpose of raising the position of the rotation axis by raising the position of the support end. Specifically, this embodiment sets the distance from the support end to the bottom surface of the receiving cavity to be greater than the distance from the support end to the top surface of the receiving cavity, so that the support end is positioned above the midpoint between the bottom and top surfaces of the receiving cavity, thereby raising the position of the support end. Since the rotating shaft is located at the support end, as the position of the support end is raised, the rotating shaft located at the support end is raised, thereby raising the position of the axis of the rotating shaft, i.e., the rotation axis.

[0019] As a non-limiting embodiment, the electronic device protective case can also be in a second state. In the second state, the second plate and the first plate are located on the same side of the rotating connection and their surfaces face each other, for clamping the electronic device between the flat areas of the second plate and the flat areas of the first plate. The electronic device protective case is provided with a first storage groove, located between the rotation axis and the flat area of ​​the first plate, for storing accessories of the electronic device, such as a stylus, in the second state. The second plate has an accessory area connected to the inner edge of the flat area of ​​the second plate. The inner edge of the flat area of ​​the second plate is the edge of the flat area of ​​the second plate facing the rotating connection in the second state. The circular rotation path of the accessory area passes through the first storage groove.

[0020] In this embodiment, when the electronic device protective case is in the first state, as the electronic device is raised, the accessory attached to the inner side of the electronic device is also raised, thus moving the accessory further away from the axis of rotation. Therefore, when the electronic device protective case switches to the second state, the accessory shifts towards the side where the flat plate area of ​​the first plate is located.

[0021] In order to enable the accessories to be automatically removed or automatically returned to the first storage slot when they are attached to the inner side of the electronic device, in this embodiment, the first storage slot is located between the rotation axis and the flat plate area of ​​the first plate, and the circular rotation path of the accessory area passes through the first storage slot.

[0022] Compared to related technologies where the rotation axis passes through the first storage slot, the first storage slot is located between the rotation axis and the flat plate area of ​​the first plate, and is not passed through by the rotation axis. This is equivalent to it being offset to the side where the flat plate area of ​​the first plate is located, so that when the electronic device protective case is in its second state, accessories offset to the side where the flat plate area of ​​the first plate is located can be stored. When the electronic device protective case is in its second state, since the flat plate area of ​​the second plate faces the electronic device, and the accessory is attached to the inner side of the electronic device, the accessory area connected to the inner side of the flat plate area is opposite to the accessory. Therefore, the circular rotation trajectory of the accessory area around the rotation axis can characterize the circular rotation trajectory of the accessory around the rotation axis. Based on this, when the circular rotation trajectory of the accessory area passes through the first storage slot, the circular rotation trajectory of the accessory around the rotation axis also passes through the first storage slot, allowing the electronic device to automatically return the accessory to the first storage slot.

[0023] As a non-limiting embodiment, the accessory area is configured with a second storage slot. In the second state, the second storage slot and the first storage slot together form a storage cavity, which is used to store accessories.

[0024] In this embodiment, by storing accessories by opening a second storage slot in the accessory area, the thickness of the electronic device protective case in the first direction can be reduced in the second state.

[0025] As a non-limiting embodiment, the rotating connection includes a top surface and a bottom surface facing away from each other in a first direction, a first side surface and a second side surface facing away from each other in a second direction, and a third side surface and a fourth side surface facing away from each other in the direction of the rotation axis. The second direction is perpendicular to both the direction of the rotation axis and the first direction. A first plate portion is located on one side of the second side surface. The top reference surface is the reference surface where the top surface of the rotating connection is located.

[0026] As a non-limiting embodiment, the distance between the rotation axis and the first side in the second direction is greater than the distance between the rotation axis and the second side in the second direction. This arrangement effectively shifts the center of gravity of the electronic device protective case in its first state towards the side facing the second side, making it less prone to tipping over when the electronic device is attached, thus enhancing the stability of the protective case's support function.

[0027] As a non-limiting embodiment, the width of the rotating connection in the second direction is greater than its thickness in the first direction; the rotation axis is located between the center line of the width of the rotating connection and the first plate portion. In this embodiment, by widening the width of the rotating connection, the rotation axis is positioned between the center line of the width of the rotating connection and the first plate portion, causing the rotation axis to shift from its central position towards the side where the first plate portion is located in the width direction of the rotating connection. This results in the distance between the rotation axis and the first side surface in the second direction being greater than the distance between the rotation axis and the second side surface in the second direction.

[0028] As a non-limiting embodiment, the third and fourth sides are formed by the sides corresponding to the width and thickness of the rotating connection, and one or more of the third and fourth sides are provided with an interface. Since the third and fourth sides are formed by the sides corresponding to the width and thickness of the rotating connection, when the width of the rotating connection is greater than its thickness, the shape of the third and fourth sides is rectangular. This makes the size of the third and fourth sides larger, providing conditions for providing an interface.

[0029] Secondly, embodiments of this application provide an electronic device kit. The electronic device kit includes an electronic device and an electronic device protective case as described in any of the first aspects. When the electronic device is fixed to the second plate portion of the electronic device protective case, the electronic device can rotate with the second plate portion, and when the electronic device protective case is in a first state, it has an angle with the first plate portion.

[0030] It should be noted that the beneficial effects of the electronic device kit provided in the second aspect can be found in the relevant description of the electronic device protective case provided in any embodiment of the first aspect above, and will not be repeated here.

[0031] As a non-limiting embodiment, the electronic device includes a first portion and a second portion. In a first state, the second portion is supported on a second rotating plate portion of the second plate portion, and the first portion is separated from the first rotating plate portion and extends towards the user input area along the plate surface direction of the second rotating plate portion.

[0056] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments.

[0057] This application provides an electronic device kit, which includes an electronic device, accessories, and a protective case for the electronic device. The electronic device can be a tablet computer, a mobile phone, or other device with a plate-like structure. Accessories are components that are separate from the electronic device but can be used with it, such as a stylus. The following description uses a tablet computer as the electronic device, a stylus as the accessory, and a tablet computer protective case as the protective case.

[0058] For example, please refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of a tablet computer kit 000 in the off state, provided in an embodiment of this application. Figure 2 for Figure 1 The diagram shows the structure of the tablet PC kit 000 in the open state.

[0059] The tablet computer kit 000 includes a tablet computer 001, a stylus 002, and a tablet computer case 003. It is understood that the figures only schematically show some of the components included in the tablet computer kit 000; in actual implementation, the tablet computer kit 000 may include more or fewer components. For example, the tablet computer kit 000 may not include the stylus 002. Furthermore, the actual shape, size, position, and construction of each component are not limited to the structure shown in the figures.

[0060] It should be noted that the tablet computer 001, stylus 002, and tablet computer case 003 included in the tablet computer kit 000 can be sold separately or as a package. When sold as a package, the tablet computer 001, tablet computer case 003, and stylus 002 can be in a detached state; that is, the tablet computer 001 is not installed on the tablet computer case 003, and the stylus 002 is not magnetically attached to the tablet computer 001. Figure 1 and Figure 2 The state shown is described below. Exemplary descriptions of each component of the tablet PC kit 000 are provided below.

[0061] First, let's take the tablet computer 001 as an example.

[0062] The tablet computer 001 is roughly plate-shaped. The technical term "plate-shaped structure" refers to a structure where the side length of the plate surface is much greater than its thickness. The thickness direction of the plate-shaped structure is perpendicular to its surface. Because the side length of the plate surface is much greater than its thickness, the plate surface is the largest surface area in a plate-shaped structure. Similar terms to "plate" used in the embodiments of this application can be understood with reference to the explanations herein.

[0063] As a non-restrictive example, Figure 1 and Figure 2 The tablet computer 001 in this application has a rectangular plate-like structure, therefore, the surface of the tablet computer 001 has a long side and a short side. In this embodiment, the direction in which the long side of the tablet computer 001 extends is referred to as the length direction of the tablet computer 001. In this embodiment, the direction in which the short side of the tablet computer 001 extends is referred to as the width direction of the tablet computer 001. Of course, in some other embodiments, Figures 1 to 2 The tablet computer 001 can also be constructed as a plate of other shapes, which is not limited in this application embodiment.

[0064] For ease of description below, an XYZ coordinate system is established, and defined as follows: Figure 1 In the closed state shown, the length direction of tablet computer 001 is the X-axis, the width direction is the Y-axis, and the thickness direction is the Z-axis. It should be noted that the coordinate system can be flexibly set according to actual needs.

[0065] Tablet 001 has Figure 2 The display surface shown is used by the tablet computer 001 to present images or videos to the user.

[0066] Next, the stylus 002 will be illustrated by example.

[0067] The stylus 002, also known as a touch pen, is used by the user to perform input operations such as writing and clicking on the display surface of the tablet computer 001. Optionally, the stylus 002 can be a capacitive stylus, an electromagnetic induction stylus, a pressure-sensitive stylus, an active Bluetooth stylus, an optical tracking stylus, a resistive stylus, etc. This application embodiment does not limit the type of stylus 002.

[0068] As a non-limiting embodiment, such as Figure 2 As shown, the stylus 002 can be magnetically attached to the side of the tablet 001. For example, Figure 2 The stylus 002 is magnetically attached to the inner side 001a of the tablet 001 along the Y-axis. Figure 1 In the second state shown, the inner side 001a of the tablet computer 001 is hidden by the tablet computer case 003. In some other embodiments, the stylus 002 may also be attached to other locations on the tablet computer 001.

[0069] With the stylus 002 magnetically attached to the tablet 001, it is less likely to be lost. Furthermore, if the tablet 001 supports wireless charging, the stylus 002 attached to the tablet 001 can also be charged by the tablet 001.

[0070] The following is an example of a tablet computer protective case 003.

[0071] In this embodiment of the application, the tablet computer protective case 003 is... Figure 1 The state shown is called the second state of the tablet case 003; the tablet case 003 is placed on... Figure 2 The state shown is called the first state of tablet case 003.

[0072] It can be understood that the second state of the tablet case 003, i.e., the tablet kit 000, is in... Figure 1 The tablet case 003 is shown in its closed state; the first state of the tablet case 003, i.e., the tablet kit 000 is in the closed state. Figure 2 The tablet case 003 is shown in its open state.

[0073] Tablet PC Protective Case 003 can be made by Figure 1The second state shown has been switched to Figure 2 The first state shown can also be derived from... Figure 2 The first state shown has switched to Figure 1 The second state is shown.

[0074] Tablet PC Protective Case 003 Figure 1 In the second state shown, the tablet computer 001 is sandwiched in the tablet computer protective case 003, which can effectively prevent the tablet computer 001 from being damaged by scratches, collisions and drops, and can also reduce the space occupied by the tablet computer kit 000, making it easier to store and carry.

[0075] Tablet PC Protective Case 003 Figure 2 In the first state shown, a stand function is provided, stably supporting the tablet 001 on the support surface P1 (such as a desktop) without requiring the user to hold it, and displaying the tablet 001's screen to the user, facilitating other activities requiring two hands, such as typing, while viewing the tablet 001. Figure 2 In the first state shown, the display surface of the tablet computer 001 can present information such as images or videos to the user.

[0076] It should be noted that, in some other embodiments, the open state of the tablet PC kit 000 is not limited to... Figure 2 The state shown. The tablet suite 000 can have more forms when it is open. For example, Figure 3 This demonstrates another open state of the Tablet Kit 000. It can be understood that the Tablet Kit 000 is in [position / state]. Figure 3 The state of the tablet case 003 in the open state shown can also be referred to as the first state of the tablet case 003. Unless otherwise stated, subsequent embodiments will use... Figure 2 The state of the tablet computer case 003 shown is the first state of the tablet computer case 003, which will be used as an example for explanation.

[0077] The following section will explain the two states of the tablet protective case 003 in detail, taking into account the various components of the tablet protective case 003.

[0078] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the structure of a tablet computer protective case 003 in the first state, provided as an embodiment of this application. Figure 4 Equivalent to in Figure 2 The tablet computer 001 and stylus 002 have been removed from the original design. Figure 4 As can be seen, the tablet computer protective case 003 includes a first plate portion 100, a second plate portion 200, and a rotating connecting portion 300.

[0079] First, the rotating connection part 300 will be described by way of example.

[0080] The rotating connecting portion 300 can be constructed as an elongated structure. An elongated structure refers to a structure whose length is significantly greater than its width and height. The length direction of the rotating connecting portion 300 is the X-axis direction. Furthermore, in this embodiment, the width of the rotating connecting portion 300 is greater than its height; the width direction of the rotating connecting portion 300 is the Y-axis direction as shown in the figure, and the height direction of the rotating connecting portion 300 is the Z-axis direction as shown in the figure.

[0081] The rotating connection part 300 includes a top surface S11, a bottom surface S12, and four side surfaces located between the top surface S11 and the bottom surface S12 and intersecting the top surface S11 and the bottom surface S12, namely the first side surface S21, the second side surface S22, the third side surface S23, and the fourth side surface S24.

[0082] The top surface S11 and bottom surface S12 are arranged facing away from each other in the Z-axis direction, and both are generally planes extending along the XY plane. The first side surface S21 and the second side surface S22 are arranged facing away from each other in the X-axis direction. The first side surface S21 is an arc-shaped surface, and the second side surface S22 is an inclined plane relative to the XY plane. The third side surface S23 and the fourth side surface S24 are arranged facing away from each other in the Y-axis direction, and both are generally planes extending along the YZ plane.

[0083] Of course, in some other embodiments, the rotating connection portion 300 may also be constructed in other shapes, and this application embodiment does not limit this.

[0084] Next, the first plate portion 100 will be described by way of example.

[0085] The first plate 100 is generally rectangular in shape to facilitate... Figure 4 In the first state shown, it serves as a base supported on the support surface P1. To protect the tablet computer 001, the shape of the first plate portion 100 is adapted to the shape of the tablet computer 001, having a long side and a short side. In this embodiment, the direction in which the long side of the first plate portion 100 extends is referred to as the length direction of the first plate portion 100, and the length direction of the first plate portion 100 shown in the figure is the X-axis direction; the direction in which the short side of the first plate portion 100 extends is referred to as the width direction of the first plate portion 100, and the width direction of the first plate portion 100 shown in the figure is the Y-axis direction.

[0086] The first plate portion 100 includes a first plate surface 100a and a second plate surface 100b.

[0087] Figure 4In the first state shown, the first plate surface 100a of the first plate portion 100 is in contact with the support surface P1. Therefore, the first plate surface 100a of the first plate portion 100 can also be called the bottom plate surface of the first plate portion 100. The plane where the first plate surface 100a of the first plate portion 100 is located is called the bottom plate surface reference plane P3. The bottom plate surface reference plane P3 is a virtual plane, which is shown by dashed lines in the figure. Figure 4 In the first state shown, the direction perpendicular to the base plate reference surface P3, that is, the thickness direction of the first plate portion 100, is the first direction. Figure 4 In the diagram, the first direction is the Z-axis direction.

[0088] The second plate surface 100b of the first plate portion 100 is opposite to the first plate surface 100a of the first plate portion 100 in the Z-axis direction.

[0089] As a non-limiting example, the first panel 100 may include a user input area 110 located on the second panel surface 100b of the first panel 100, configured to allow a user to input information to the tablet computer 001. Exemplarily, the user input area 110 may include a keyboard area 111 and / or a touch area 112, etc. Of course, in some other embodiments, the first panel 100 may not include the user input area 110, and this application embodiment does not limit this.

[0090] Figure 4 In this configuration, the first plate portion 100 is located on one side of the rotating connecting portion 300 in the positive Y-axis direction (i.e., one side of the second side surface S22 of the rotating connecting portion 300) and is fixedly connected to the rotating connecting portion 300. Exemplarily, the first plate portion 100 and the rotating connecting portion 300 are integrally formed structures.

[0091] Of course, in some other embodiments, the first plate portion 100 may also be rotatably connected to the rotating connecting portion 300. In this application embodiment, the technical term "rotating connection" refers to a connection method in which two components can rotate relative to each other. In this case, the first plate portion 100 can rotate relative to the rotating connecting portion 300, so that the tablet computer protective case 003 can have more shapes, for example, the first plate portion 100 can rotate to the side where the first side surface S21 of the rotating connecting portion 300 is located. This application embodiment does not limit the connection method between the first plate portion 100 and the rotating connecting portion 300, as long as the first plate portion 100 can serve as a base to support the tablet computer protective case 003 on the support surface P1 so that the tablet computer 001 can display the display surface to the user.

[0092] Next, the second plate section 200 will be described by way of example.

[0093] The second plate portion 200 is rotatably connected to the rotating connecting portion 300 about the rotation axis O1. The rotation axis O1 is a virtual straight line extending along the X-axis direction, shown as a dashed line in the figure. The rotatable connection of the second plate portion 200 about the rotation axis O1 to the rotating connecting portion 300 means that the second plate portion 200 and the rotating connecting portion 300 are rotatably connected and can rotate relative to the rotating connecting portion 300 about the rotation axis O1. The meaning of subsequent references to the rotatable connection of a component about the rotation axis O1 to the rotating connecting portion 300 can be found in this explanation.

[0094] When the second plate portion 200 is rotatably connected to the rotatable connecting portion 300, the second plate portion 200 can rotate relative to the rotatable connecting portion 300 and the first plate portion 100, thereby changing the angle between the second plate portion 200 and the first plate portion 100.

[0095] Optionally, the second plate portion 200 includes a connecting portion 211, which is disposed at one end of the second plate portion 200 facing the rotating connecting portion 300. Specifically, the second plate portion 200 is rotatably connected to the rotating connecting portion 300 about the rotation axis O1 via the connecting portion 211. Figure 4 In this design, the connecting portion 211 is manifested as a protrusion on a flat plate surface, and there are two connecting portions 211. The two connecting portions 211 are spaced apart in the X-axis direction to facilitate the fitting area 212 between the two connecting portions 211 for use in... Figure 1 The stylus 002 is obscured in the shown state. In some other embodiments, the connecting portion 211 may also have other structures, such as the connecting portion 211 not protruding from the flat surface. The number of connecting portions 211 is not limited to two, but may be more.

[0096] The second plate portion 200 is used to fix the aforementioned tablet computer 001. For example, the second plate portion 200 has a cavity and a magnetic module disposed within the cavity. The second plate portion 200 fixes the aforementioned tablet computer 001 by magnetically attracting it through the magnetic force of the magnetic module. Please refer to the reference. Figure 1 and Figure 2 When the tablet computer 001 is fixed to the second plate 200, it can rotate with the second plate 200 to adjust its display angle.

[0097] As a limiting embodiment, the second plate portion 200 may include a first rotating plate portion 210 and a second rotating plate portion 220. Of course, in some other embodiments, the second plate portion 200 may also be a complete and non-foldable plate structure, and this application embodiment does not limit this.

[0098] Specifically, the first rotating plate portion 210 is rotatably connected to the rotating connection portion 300 around the rotation axis O1. In this case, the connection portion 211 is provided at the end of the first rotating plate portion 210 facing the rotating connection portion 300, that is, at the end opposite to the end of the first rotating plate portion 210 that is connected to the second rotating plate portion 220.

[0099] When the first rotating plate portion 210 is rotatably connected to the rotating connecting portion 300, the first rotating plate portion 210 can drive the second rotating plate portion 220 to rotate relative to the rotating connecting portion 300. The rotation of the first rotating plate portion 210 relative to the rotating connecting portion 300 can change the first angle α1 between the first rotating plate portion 210 and the first plate portion 100.

[0100] It should be noted that the first angle α1 between the first rotating plate portion 210 and the first plate portion 100 refers to the angle between the plane where the plate surface of the first rotating plate portion 210 is located (shown by dashed lines in the figure) and the bottom plate reference plane P3, and the angle with the side where the first plate surface 100a of the first plate portion 100 is located, that is, the angle whose side includes the first plate surface 100a of the first plate portion 100.

[0101] The second rotating plate portion 220 is rotatably connected to the opposite side of the rotating connection portion 300 connecting the first rotating plate portion 210. For example, the first rotating plate portion 210 and the second rotating plate portion 220 are rotatably connected by a lightweight miniature rotating shaft 421, which reduces the weight of the rotating shaft itself and the number of magnets, thereby reducing the weight of the second plate portion 200. As the weight of the second plate portion 200 is reduced, Figure 4 In the state shown, the tablet protective case 003 is not easy to tip over after being attached to the tablet 001.

[0102] When the second rotating plate portion 220 and the first rotating plate portion 210 are rotatably connected, the second rotating plate portion 220 can rotate relative to the first rotating plate portion 210, thereby changing the included angle β between the second rotating plate portion 220 and the first rotating plate portion 210, and further changing the second angle α2 between the second rotating plate portion 220 and the first plate portion 100.

[0103] It should be noted that the included angle β between the second rotating plate portion 220 and the first rotating plate portion 210 refers to the angle less than or equal to 90° formed by the intersection of the plane containing the plate surface of the second rotating plate portion 220 (shown by dashed lines in the figure) and the plane containing the plate surface of the first rotating plate portion 210 (shown by dashed lines in the figure).

[0104] The intersection line formed by the plane containing the surface of the second rotating plate portion 220 (shown as a dashed line in the figure) and the plane containing the first plate surface 100a of the first plate portion 100 (shown as a dashed line in the figure) divides the first plate surface 100a of the first plate portion 100 into a larger plate surface and a smaller plate surface, with the area of ​​the larger plate surface being greater than the area of ​​the smaller plate surface. The second angle α2 between the second rotating plate portion 220 and the first plate portion 100 refers to the angle on the side containing the larger plate surface among the two angles formed by the intersection of the plane containing the surface of the second rotating plate portion 220 and the plane containing the surface of the first plate portion 100.

[0105] Tablet case 003 is in Figure 1 In the second state shown, the angle between the second rotating plate portion 220 and the first rotating plate portion 210 is zero, causing the second plate portion 200 to be approximately flattened into a rectangular plate structure. The first angle is zero, causing the flattened rectangular plate structure of the second plate portion 200 and the first plate portion 100 to be located on the same side of the rotating connection portion 300 and facing each other, so that the tablet computer 001 can be sandwiched between the tablet area 200a of the second plate portion 200 and the tablet area 100c of the first plate portion 100, protecting the tablet computer 001 from scratches, collisions, drops, and other damage. Because the display surface of the tablet computer 001 is hidden and cannot be displayed, this state of the tablet computer kit 000 is referred to as the closed state.

[0106] The flat plate area 200a of the second plate section 200 is Figure 1 In the second state shown, the area of ​​the second board portion 200 directly faces the tablet computer 001; the tablet area 100c of the first board portion 100 is... Figure 1 In the second state shown, the area where the first plate portion 100 faces the tablet computer 001. Furthermore, embodiments of this application will... Figure 1 In the second state shown, the portion of the tablet computer 001 facing the first rotating plate portion 210 is called the first portion 011 of the tablet computer 001, and the portion of the tablet computer 001 facing the second rotating plate portion 220 is called the second portion 012 of the tablet computer 001. The area where one component faces another component refers to the area corresponding to the orthographic projection of the other component onto the first component.

[0107] Tablet case 003 is in Figure 2 and Figure 4In the first state shown, the first angle α1 is approximately 90° and the included angle β is approximately 35°, making the second angle α2 greater than the first angle α1, approximately 120°, which is the sum of the first angle α1 and the included angle β. The second part 012 of the tablet computer 001 fixes the second rotating plate part 220, and the first part 011 of the tablet computer 001 is separated from the first rotating plate part 210, so that the tablet computer 001 presents the display surface to the user at a first angle (e.g., 125°) relative to the supporting surface P1. Therefore, the state of the tablet computer kit 000 is referred to as the open state.

[0108] In some other embodiments, when the tablet computer protective case 003 is in... Figure 3 In the first state shown, the included angle β is zero, so the second plate portion 200 remains roughly flattened into a rectangular plate structure; the first angle α1 is 90°, so the second angle α2 between the flattened rectangular plate portion 200 and the first plate portion 100 is also 90°. When the tablet computer 001 is fixed with the second rotating plate portion 220, the tablet computer 001 presents its display surface to the user at a 90° angle relative to the supporting surface P1. Therefore, the state of the tablet computer kit 000 is also referred to as the open state.

[0109] exist Figures 2 to 4 In the first state shown, the first angle α1 between the first rotating plate portion 210 and the first plate portion 100 and the second angle α2 between the second rotating plate portion 220 and the first plate portion 100 can be set such that the second rotating plate portion 220 is fixed to the tablet computer 001 and supported on the support surface P1 by the first plate portion 100, so that the display surface can be shown to the user as the standard.

[0110] Optionally, the second angle α2 is greater than or equal to 90°. For example, Figure 2 and Figure 4 In this case, the second angle α2 is approximately 125°, designed to present the user with a relatively tilted display surface, providing a more comfortable viewing angle; for example, Figure 3 In the middle, the second angle α2 is approximately 90°, so as to present a relatively upright display surface to the user.

[0111] It should be noted that, in specific implementations, the tablet PC kit 000 can have more open states, and correspondingly, the tablet PC protective case 003 can also have more first states. Users can choose one of these states for use. Subsequent embodiments will use the first state of the tablet PC protective case 003 as an example. Figure 2 and Figure 4 The state shown is used as an example for explanation.

[0112] Please refer to Figure 5 , Figure 5 for Figure 2 The side view of the tablet kit 000 shown, specifically from Figure 2 The third side (S23) of the tablet case 003 is shown. This is understandable. Figure 5 The tablet kit 000 shown is in the open state, and correspondingly, the tablet protective case 003 is in the first state.

[0113] exist Figure 5 In the first state shown, the second plate portion 200 rotates to the side where the top reference surface P2 faces away from the bottom plate reference surface P3. The top reference surface P2 passes through the top of the rotating connection portion 300 and is perpendicular to the Z-axis direction. The top of the rotating connection portion 300 is the position in the Z-axis direction where the rotating connection portion 300 is furthest away from the bottom plate reference surface P3.

[0114] Figure 5 In this embodiment, the top surface S11 of the rotating connection portion 300 is a plane, and all points on the top surface S11 of the rotating connection portion 300 are equidistant from the bottom plate reference surface P3. Therefore, all points on the top surface S11 of the rotating connection portion 300 can be considered as the top of the rotating connection portion 300. In this case, the top reference surface P2 is the plane on which the top surface S11 of the rotating connection portion 300 is located. In some other embodiments, the rotating connection portion 300 may be irregular. Therefore, in this case, the top of the rotating connection portion 300 is defined by the position of the rotating connection portion 300 furthest from the bottom plate reference surface P3 in the Z-axis direction.

[0115] For related technologies, please refer to Figure 6 , Figure 6 This is a side view of a tablet computer kit 000 in the open state. In the open state, a portion of the second plate portion 200 (such as the connecting portion 211) is located on the side of the rotating connecting portion 300 with the top reference surface P2 facing the bottom plate reference surface P3.

[0116] By comparison Figure 5 and Figure 6 It can be observed that, even with the tablet suite 000 open, Figure 5 The second plate portion 200 is located on the side of the rotating connection portion 300 opposite to the bottom plate reference surface P3, which is the top reference surface P2. Figure 6 The second plate portion 200 (such as the connecting portion 211) is located on the side of the rotating connecting portion 300 where the top reference surface P2 faces the bottom plate reference surface P3. Using the bottom plate reference surface P3 as a reference, Figure 5 The second plate section 200 ratio Figure 6 The second plate portion 200 is further away from the bottom plate reference plane P3, that is... Figure 5 The second plate section 200 ratio Figure 6The second plate section 200 is positioned higher.

[0117] As an example of the second plate section 200 being raised, such as Figure 5 As shown, there is a gap between the second plate portion 200 and the top reference surface P2.

[0118] Tablet case 003 is in the first state, because Figure 5 The second plate section 200 ratio Figure 6 With the second board 200 positioned higher, the tablet computer 001 fixed to the second board 200 is also raised to a higher position. As the tablet computer 001 is raised, its display screen is also raised, providing the user with a more comfortable viewing experience.

[0119] In addition, Figure 5 In the first state shown, the second angle α2 is greater than the first angle α2. In this case, the second part 012 of the tablet computer 001 is fixed to the second rotating plate 220, and the first part 011 of the tablet computer 001 separates from the first rotating plate 210 and extends along the plate surface direction of the second rotating plate 220 towards the user input area 110, thus getting closer to the user input area 110. Therefore, there is a risk that the user's hand may be blocked by the tablet computer 001 when operating the user input area 110; conversely, the tablet computer 001 is also easily blocked by the hand, affecting the viewing experience.

[0120] In this embodiment, as the tablet computer 001 is raised, it moves further away from the user input area 110 along the Z-axis. This reduces the risk of the user's hand being blocked by the tablet computer 001 while operating the user input area 110, and also reduces the risk of the screen being obstructed by the user's hand, thus improving the user's viewing experience.

[0121] As a non-limiting embodiment, please continue to refer to Figure 5 Because raising the tablet computer 001 increases the overall center of gravity, optionally, the first angle α1 is less than 90° to reduce the risk of the tablet computer kit 000 tipping over in the direction indicated by the dotted line M1 with arrows in the illustration.

[0122] As a non-limiting embodiment, please continue to refer to Figure 5The distance L21 between the rotation axis O1 (indicated by dots in the diagram due to perspective) and the first side surface S21 along the Y-axis is greater than the distance L22 between the rotation axis O1 and the second side surface S22 along the Y-axis. The distance L21 between the rotation axis O1 and the first side surface S21 along the Y-axis refers to the distance between the two intersection points formed by a straight line along the Y-axis intersecting both the rotation axis O1 and the first side surface S21. The definition of the distance L22 between the rotation axis O1 and the second side surface S22 along the Y-axis is similar.

[0123] This setting is equivalent to shifting the center of gravity of the tablet protective case 003 in the first state towards the positive direction of the Y-axis (that is, the side that the second side S22 faces). When the tablet 001 is attached, it is less likely to tip over in the direction indicated by the dotted line M1 with arrows in the figure, thus improving the stability of the stand function of the tablet protective case 003.

[0124] For example, please continue to refer to Figure 5 The width of the rotating connecting portion 300 in the Y-axis direction is greater than its thickness in the Z-axis direction; the rotation axis O1 is located between the center line O3 of the width of the rotating connecting portion 300 (perpendicular to the Y-axis direction and passing through the midpoint of the smaller width) and the first plate portion 100. In this embodiment, by widening the width of the rotating connecting portion 300, the rotation axis O1 is positioned between the center line O3 of the width of the rotating connecting portion 300 and the first plate portion 100, causing the rotation axis O1 to shift from its central position to the side where the first plate portion 100 is located in the width direction (Y-axis direction shown in the figure). This results in the distance L21 between the rotation axis O1 and the first side surface S21 in the Y-axis direction being greater than the distance L22 between the rotation axis O1 and the second side surface S22 in the Y-axis direction.

[0125] Because the third side S23 and the fourth side (not shown in the illustration) of the rotating connecting portion 300 are formed by the edges corresponding to the width and thickness of the rotating connecting portion 300, when the width of the rotating connecting portion 300 is greater than its thickness, the third side S23 and the fourth side are rectangular in shape. This increases the size of the third side S23 and the fourth side, providing conditions for setting up an interface. Based on this, as a non-limiting embodiment, one or more of the third side S23 and the fourth side are provided with an interface (not shown in the illustration). The interface can be a USB interface, an HDMI interface, a 3.5mm headphone jack, an SD card slot, a SIM card slot, an Ethernet port, etc.

[0126] As a non-limiting embodiment, please continue to refer to Figure 5 , Figure 5The image shows the circular rotational trajectory N1, depicted by dashed lines, representing the rotation path of the connecting part 211 around the rotation axis O1. This circular trajectory N1 is the extended circular trajectory obtained by extending the arc path of the connecting part 211 rotating around the rotation axis O1 from the position closest to it. The radius of this circular trajectory N1 is the rotation radius R1 of the connecting part 211 around the rotation axis O1. Figure 5 As can be seen, when the rotation radius R1 is greater than the distance L11 (vertical distance) from the rotation axis O1 to the top reference surface P2, the connecting part 211 can rotate to the side of the top reference surface P2 that faces away from the bottom plate reference surface P3 without being blocked by the rotating connecting part 300, thereby achieving the purpose of raising the tablet computer 001.

[0127] It should be noted that since the connecting part 211 can represent the end of the second plate 200 facing the rotating connecting part 300, that is, the part of the second plate 200 closest to the rotating connecting part 300, when the connecting part 211 can be rotated to the side where the top reference surface P2 is away from the bottom plate reference surface P3, it means that the part of the second plate 200 closest to the rotating connecting part 300 and other more distant parts can be rotated to the side where the top reference surface P2 is away from the rotation axis O1, thereby achieving the purpose of raising the tablet computer 001.

[0128] Based on this, the embodiments of this application provide Figure 7 The pivot assembly 400 in the middle allows the connecting part 211 to be rotatably connected to the rotating connecting part 300 through the pivot assembly 400. This enables the rotating radius R1 of the connecting part 211 to be greater than the distance L11 from the rotating axis O1 to the top reference surface P2, thereby achieving the purpose of raising the tablet computer 001.

[0129] As a non-limiting embodiment, please refer to Figure 7 , Figure 7 This is a schematic diagram of the structure of the rotating shaft assembly 400 provided in the embodiments of this application.

[0130] Depend on Figure 7 As can be seen, the rotating shaft assembly 400 may include a rotating shaft bracket 410 and an arc rotating component 420.

[0131] First, the rotating shaft bracket 410 will be described by example.

[0132] The pivot bracket 410 includes a base plate 411, a support end 412, and a connecting rod 413.

[0133] The base plate 411 is a component of the pivot bracket 410 used to fix the aforementioned rotating connection part 300.

[0134] The support end 412 is located on one side of the base plate 411 and is constructed as a notched arc-shaped structure to accommodate the mounting of the rotating shaft 421. The arc-shaped support end 412 is approximately centered on the rotation axis O1.

[0135] The connecting rod 413 is located between the base plate 411 and the support end 412 and extends along the Z-axis, fixing the support end 412 and the base plate 411 respectively.

[0136] Figure 7 In this embodiment, the base plate 411, the support end 412, and the connecting rod 413 are integrally formed and are roughly inverted T-shaped. In other embodiments, the base plate 411, the support end 412, and the connecting rod 413 can be independently formed components, which are then processed to form the aforementioned pivot bracket 410.

[0137] Next, the circular arc rotating component 420 will be described by way of example.

[0138] The circular arc rotating component 420 includes a rotating shaft 421, a circular arc portion 422, a connecting plate 423, and a fixing portion 424.

[0139] The rotating shaft 421 is embedded in the support end 412 and rotates around the rotation axis O1 within the support end 412. Figure 7 In this embodiment, the rotating shaft 421 is embedded in the support end 412, so that the rotating shaft 421 is rotatably disposed on the support end 412. In some other embodiments, the rotating shaft 421 may also be rotatably disposed on the support end 412 in other ways, and this application embodiment does not limit this.

[0140] The arc portion 422 is constructed as an arc plate, meaning its radial thickness is much smaller than its circumferential and axial dimensions. The arc portion 422 is centered on the rotation axis O1, and its axial direction is the direction of the rotation axis O1, i.e., the X-axis direction shown in the figure. Of course, in other embodiments, the arc portion 422 can also be constructed as an arc structure of other shapes, such as a strip-shaped arc structure, etc.

[0141] The arc portion 422 has an outer peripheral surface 422a and an inner peripheral surface 422b distributed radially. The outer peripheral surface 422a of the arc portion 422 is farther away from the axis of rotation 421 than the inner peripheral surface 422b.

[0142] The arc portion 422 has two arc ends distributed in the circumferential direction. For ease of distinction and explanation, these two arc ends are referred to as the first arc end 4221 and the second arc end 4222, respectively, in this embodiment. The first arc end 4221 is used to fix the connecting portion 211. For example, the first arc end 4221 is fixed to the connecting portion 211 by a connecting plate 423. In this case, the first arc end 4221 (i.e., the arc connecting end) is fixedly connected to the connecting plate 423, which extends outward from the outer peripheral surface 422a of the arc portion 422, and the connecting plate 423 is provided with a through hole 4231.

[0143] The fixing part 424 fixes the arc-shaped part 422 and the rotating shaft 421 respectively, thereby achieving a fixed connection between the arc-shaped part 422 and the rotating shaft 421. With the arc-shaped part 422 and the rotating shaft 421 fixedly connected, the arc-shaped part 422 can rotate around the rotation axis O1 with the rotating shaft 421. The position of the arc-shaped part 422 shown in the figure is when the tablet computer protective case is in its first state.

[0144] Figure 7 In this embodiment, the fixing part 424 extends radially along the arc portion 422. One end of the fixing part 424 fixes the rotating shaft 421, and the other end of the fixing part 424 fixes the arc portion 422, for example, the second arc end 4222 of the arc portion 422 is fixed at the other end. In some other embodiments, the fixing part 424 may also have other structures, as long as it can fix the arc portion 422 and the rotating shaft 421.

[0145] Figure 7 In this embodiment, the rotating shaft 421, the arc portion 422, the fixing portion 424, and the connecting plate 423 are integrally formed. In other embodiments, the rotating shaft 421, the arc portion 422, the fixing portion 424, and the connecting plate 423 can be independently formed components, and the aforementioned arc rotating component 420 can be formed through secondary processing.

[0146] The following is combined Figure 8 ,right Figure 7 The connection relationship between the rotating shaft assembly 400 and the rotating connection part 300 and the connection part 211 will be explained.

[0147] For example, please refer to Figure 8 , Figure 8 for Figure 4 The diagram shows a cross-sectional view of the tablet protective case 003 along section line Q1-Q1. It can be understood that... Figure 8 The tablet case 003 shown is in the first state.

[0148] Figure 8In the middle, the rotating connection part 300 has a receiving cavity 310. The receiving cavity 310 has a bottom surface 310a and a top surface 310b opposite to each other in the Z-axis direction, and the top surface 310b of the receiving cavity 310 is closer to the top reference surface P2 than the bottom surface 310a.

[0149] In order to accommodate the inverted T-shaped pivot bracket 410, the receiving cavity 310 is also generally configured to have an inverted T-shaped cross section. In this case, the rotating connection 300 has a boss 311 for constructing the receiving cavity 310.

[0150] The hinge bracket 410 is fixed within the receiving cavity 310 of the rotating connection portion 300. For example, the base plate 411 of the hinge bracket 410 is fixed to the boss 311 by screws or other fasteners. In other embodiments, the base plate 411 and the boss 311 can be fixed in other ways. When the hinge bracket 410 is fixed within the receiving cavity 310 of the rotating connection portion 300, the hinge bracket 410 is hidden within the rotating connection portion 300, which helps to improve the appearance of the tablet computer protective case 003.

[0151] In this embodiment, the rotating shaft 421 is rotatably mounted on the support end 412 of the rotating shaft bracket 410, and the rotating shaft bracket 410 fixes the rotating connection part 300, thereby realizing the rotatable connection between the rotating shaft 421 and the rotating connection part 300 around the rotation axis O1 (indicated by dots in the figure). In some other embodiments, the rotating shaft 421 can also be rotatably connected to the rotating connection part 300 in other ways. For example, a bushing for mounting the rotating shaft 421 is provided on the side wall of the receiving cavity 310 of the rotating connection part 300. The rotating shaft 421 extends into the bushing and can slide relative to the bushing, thereby realizing the rotatable connection between the rotating shaft 421 and the rotating connection part 300. In this case, the rotating shaft assembly may not include the rotating shaft bracket 410.

[0152] Because the rotating shaft 421 is rotatably connected to the rotating connection part 300 around the rotation axis O1, and the arc part 422 is fixedly connected to the rotating shaft 421 through the fixing part 424, the arc part 422 can rotate relative to the rotating connection part 300 around the rotation axis O1 with the rotating shaft 421, thereby realizing the rotatable connection between the arc part 422 and the rotating connection part 300 around the rotation axis O1. In some other embodiments, the arc part 422 can be rotatably connected to the rotating connection part 300 in other ways. For example, the arc part 422 can be an arc-shaped sliding part fixedly connected to the connection part 211, and the rotating connection part 300 is correspondingly provided with an arc-shaped sliding fit part. The arc-shaped sliding part is one of an arc-shaped groove and an arc-shaped slide rail, and the arc-shaped sliding fit part is the other of an arc-shaped groove and an arc-shaped slide rail. The arc-shaped slide rail is placed in the arc-shaped groove and can slide relative to it along the arc-shaped trajectory, thereby realizing the rotatable connection between the arc part 422 and the rotating connection part 300.

[0153] The receiving cavity 310 has an opening 312 that penetrates the second side surface S22. A portion of the arcuate portion 422 is placed inside the receiving cavity 310, and the portion of the arcuate portion 422 including the first arcuate end 4221 extends through the opening 312 to the outside of the receiving cavity 310 so that the first arcuate end 4221 can be fixedly connected to the connecting portion 211 outside the receiving cavity 310.

[0154] Figure 8 In this embodiment, the connecting portion 211 includes a connecting portion cavity 2111 and a nut 2112 fixed to the connecting portion cavity 2111. A connecting plate 423 fixedly connected to the first arc end 4221 extends into the connecting portion cavity 2111, with its through hole 4231 aligned with the nut 2112. A bolt 2113 passes through the through hole 4231 and locks with the nut 2112, thereby fixing the first arc end 4221 and the connecting portion 211. In some other embodiments, the first arc end 4221 can also be fixedly connected to the connecting portion 211 in other ways, such as the first arc end 4221 being directly fixedly connected to the connecting portion 211.

[0155] Tablet PC protective case 003 is made by Figure 1 The second state shown Figure 2 During the first state transition shown, the connecting part 211 drives the arc part 422 to rotate counterclockwise around the rotation axis O1, causing the arc part 422 to gradually extend out of the receiving cavity 310; in the tablet computer protective case 003, from Figure 2 The first state shown Figure 1 During the second state switching process shown, the connecting part 211 drives the arc part 422 to rotate clockwise around the rotation axis O1, so that the arc part 422 gradually retracts into the receiving cavity 310.

[0156] Figure 8 In this configuration, since the connecting portion 211 is fixedly connected to the first arc end 4221 of the arc portion 422, and the arc portion 422 is centered on the rotation axis O1, the radius of rotation of the connecting portion 211 around the rotation axis O1 is approximately equal to the radius R2 of the arc portion 422. The radius R2 of the arc portion 422 is approximately the distance from the rotation axis O1 to the first arc end 4221. Because the connecting portion 211 is close to the outer peripheral surface 422a of the arc portion 422, the distance from the rotation axis O1 to the first arc end 4221 can be determined by the distance from the rotation axis O1 to the position of the first arc end 4221 corresponding to the outer peripheral surface 422a of the arc portion 422. The radius R2 of the arc portion 422 determined accordingly is closer to the radius of rotation of the connecting portion 211.

[0157] When the rotation radius of the connecting part 211 is approximately equal to the radius R2 of the arc part 422, the rotation radius of the connecting part 211 can be controlled by controlling the radius R2 of the arc part 422. Figure 8In this configuration, the radius R2 of the arc portion 422 is greater than the distance L11 from the rotation axis O1 to the top reference surface P2, resulting in a rotation radius of the connecting portion 211 that is greater than the distance L11 from the rotation axis O1 to the top reference surface P2, thereby achieving the purpose of raising the tablet computer 001. It should be noted that the distance L11 (perpendicular distance) from the rotation axis O1 to the top reference surface P2 is equivalent to the distance between the rotation reference surface P4, which includes the rotation axis O1 and is parallel to the top reference surface P2, and the top reference surface P2.

[0158] The dimension of the rotating connection 300 in the Z-axis direction is compared to Figure 6 With the size remaining unchanged, Figure 8 The radius R2 of the middle arc portion 422 is greater than the distance L11 from the rotation axis O1 to the top reference surface P2, which is equivalent to increasing the radius R2 of the arc portion 422, that is, increasing the rotation radius of the connecting portion 211.

[0159] As a non-limiting embodiment, please continue to refer to Figure 8 The distance L12 (perpendicular distance) from the rotation axis O1 to the bottom reference surface P3 is greater than the distance L11 from the rotation axis O1 to the top reference surface P2, compared to Figure 6 When the distance from the rotation axis O1 to the bottom reference surface P3 is equal to the distance from the rotation axis O1 to the top reference surface P2, it is equivalent to raising the position of the rotation axis O1, thereby allowing... Figure 8 In the first state shown, the connecting part 211 is raised in the Z-axis direction, thereby raising the display screen of the tablet computer 001. It should be noted that the distance L12 from the rotation axis O1 to the bottom plate reference surface P3 is equivalent to the distance between the rotation reference surface P4, which includes the rotation axis O1 and is parallel to the top reference surface P2, and the bottom plate reference surface P3.

[0160] Figure 8 The illustrated embodiment achieves the desired position of the rotation axis O1 by raising the position of the support end 412. Specifically, the distance from the support end 412 to the bottom surface 310a of the receiving cavity 310 is greater than the distance from the support end 412 to the top surface 310b of the receiving cavity 310, so that the support end 412 is positioned slightly above the center between the bottom surface 310a and the top surface 310b of the receiving cavity 310, thereby making the distance from the rotation axis O1 to the bottom plate reference surface P3 greater than the distance from the rotation axis O1 to the top reference surface P2.

[0161] It should be noted that, Figure 7 and Figure 8 The pivot assembly 400 in the example is just one example. In actual implementation, the pivot assembly 400 can also have other implementation methods.

[0162] As the tablet 001 is raised, the stylus 002, which is attached to the inner side of the tablet 001, is also raised. The storage of the stylus 002 becomes a concern. The following discussion will address this issue. Figure 6 and Figure 9 A comparative explanation will be provided. For example, please refer to... Figure 9 , Figure 9 for Figure 1 The diagram shows a cross-sectional view of the tablet PC kit 000 obtained by cutting along section line Q2-Q2. It can be understood that... Figure 9 The tablet kit 000 shown is in the off state, and correspondingly, the tablet case 003 is in the second state.

[0163] In addition, to understand the storage process of the stylus 002, Figure 9 The image also uses dotted lines to show the two open states of the tablet suite 000, which are respectively Figure 2 and Figure 3 The two open states shown are for easy distinction. Figure 3 The corresponding open state is called the first open state. Figure 2 The corresponding open state is called the second open state. The tablet PC kit 000 can switch from the closed state to the second open state via the first open state; or it can switch from the second open state to the closed state via the first open state.

[0164] Depend on Figure 9 As can be seen, the tablet protective case 003 is provided with a first storage slot 113, which is used to store the stylus 002 of the tablet 001 in the second state.

[0165] In the first state, because the stylus 002 is raised, the stylus 002 is relatively... Figure 6 The stylus 002 shown is further away from the rotation axis O1. Thus, in the second state, the stylus 002 is... Figure 6 The stylus 002 shown is offset in the positive Y-axis direction. Based on this, Figure 9 In the middle, the first storage groove 113 is located between the rotation axis O1 and the flat plate area 100c of the first plate portion 100, compared to Figure 6 When the central rotation axis O1 passes through the first storage slot 113, it is equivalent to being offset in the positive Y-axis direction, so as to accommodate the stylus 002 that is offset in the positive Y-axis direction.

[0166] Combined with reference Figure 3 The first storage slot 113 extends from the rotating connection portion 300 to the first plate portion 100. In some other embodiments, the first storage slot 113 may be located only in the rotating connection portion 300 or only in the first plate portion 100.

[0167] The second plate portion 200 has a fitting area 212, which is connected to the inner edge 200b of the flat plate portion 200a of the second plate portion 200. In the second state, the inner edge 200b of the flat plate portion 200a faces the side edge of the flat plate portion 200a towards the rotating connection portion 300. Specifically, referring to reference... Figure 3 The accessory area 212 can be located between the two connecting parts 211.

[0168] In order for the stylus 002 to be automatically removed or automatically returned to the first storage slot 113 when it is attached to the inner side 001a of the tablet computer 001, the circular rotation path of the accessory area 212 passes through the first storage slot 113.

[0169] Specifically Figure 9 In the second state shown, since the tablet area 200a of the second plate 200 is facing the tablet computer 001, when the stylus 002 is attached to the inner side 001a of the tablet computer 001, the accessory area 212 connected to the inner side 200b of the tablet area 200a of the second plate 200 is opposite to the stylus 002, and the orthographic projection of the stylus 002 on the second plate 200 along the Z-axis direction falls into the accessory area 212.

[0170] Therefore, the circular rotational path N2 (virtual trajectory, shown by dashed lines in the figure) of the accessory area 212 around the rotation axis O1 can represent the circular rotational path of the stylus 002 around the rotation axis O1. It should be noted that the accessory area 212 is represented by its relatively central position in the figure, and the circular rotational path N2 of the accessory area 212 is shown.

[0171] When the circular rotation path N2 of the accessory area 212 passes through the first storage slot 113, the circular rotation path of the stylus 002 around the rotation axis O1 also passes through the first storage slot 113, so that the stylus 002 can be automatically put back into the first storage slot 113 by the tablet computer 001.

[0172] When the tablet computer 001 is placed in the tablet area 200a of the second plate portion 200 and the stylus is magnetically attached to the inner side 001a of the tablet computer 001, the stylus 002 can rotate with the tablet computer 001. The specific process by which the stylus 002 can rotate with the tablet computer 001 is as follows:

[0173] During the process of switching from the second state to the first open state and then back to the second open state, the stylus 002 first rotates with the tablet 001 around the rotation axis O1, and the stylus 002 rotates from the second position W2 corresponding to the second state to the first position W1 corresponding to the first open state; then it rotates with the tablet 001 around the rotation axis O2, and the stylus 002 rotates from the first position W1 corresponding to the first open state to the third position W3 corresponding to the second open state, and is released from the first storage slot 113 so that the user can easily take out the stylus 002.

[0174] During the process of switching from the second open state to the first open state and back to the second state, the stylus 002 first rotates with the tablet computer 001 around the rotation axis O2. The stylus 002 rotates from the third position W3 corresponding to the second open state to the first position W1 corresponding to the first open state. Then, it rotates with the tablet computer 001 around the rotation axis O1. The stylus 002 rotates from the first position W1 corresponding to the first open state to the second position W2 corresponding to the second state.

[0175] When the tablet protective case 003 is in the second state, the stylus 002 can be rotated into the first storage slot 113 of the tablet protective case 003 and is covered by the accessory area 212 of the second plate part 200 in the Z-axis direction to prevent the stylus 002 from being lost.

[0176] In this embodiment, as the tablet PC kit 000 switches from a closed state to an open state, the stylus 002 is automatically taken out by the tablet PC 001, without the user needing to actively remove it from the first storage slot 113; conversely, as the tablet PC kit 000 switches from an open state to a closed state, the stylus 002 is automatically returned to the first storage slot 113 by the tablet PC 001, without the user needing to actively return it to the first storage slot 113. This design makes it more convenient for users to take out and put away the stylus 002.

[0177] As a non-limiting embodiment, please continue to refer to Figure 9 The accessory area 212 is equipped with a second storage slot 213; in the second state, the second storage slot 213 and the first storage slot 113 are directly opposite each other in the Z-axis direction, forming a storage cavity, which is used to store the stylus 002.

[0178] In this embodiment, by storing the stylus 002 in a second storage slot 213 in the accessory area 212, the thickness of the tablet protective case 003 in the Z-axis direction can be reduced in the second state.

[0179] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
