[0051] Embodiments of this disclosure are described in detail below, with examples of these embodiments illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting it.

[0052] The following is for reference. Figures 10-16 A storage tube 100 according to an embodiment of the present disclosure is described. The storage tube 100 according to an embodiment of the present disclosure includes a tube body 1, a first magnetic element, a second magnetic element, and a pen holder 5. The tube body 1 has a storage cavity (not shown). The first magnetic element is used to form a first magnetic field and is disposed within the storage cavity. At least one of the first and second magnetic elements is a coil. The second magnetic element is movably disposed within the storage cavity between a retracted position and a delivery position.

[0053] The pen holder 5 is connected to the second magnetic component. In the first energized state, the second magnetic component moves relative to the first magnetic component from the retracted position to the ejected position, and the second magnetic component drives the pen holder 5 from the inserted position to the ejected position.

[0054] When the first magnetic component is set as a magnet and the second magnetic component is set as a coil, in the first energized state, that is, when current is passed through the second magnetic component, the second magnetic component can cooperate with the first magnetic field formed by the first magnetic component. The second magnetic component is subjected to a pushing force (Ampere force or repulsive force) in the first magnetic field formed by the first magnetic component, which causes the second magnetic component to move relative to the first magnetic component in the storage cavity.

[0055] When the first magnetic component is configured as a coil and the second magnetic component is configured as a magnet, in the first energized state, that is, when current is passed through the first magnetic component, the first magnetic component can form a first magnetic field, and the second magnetic component can cooperate with the first magnetic field formed by the first magnetic component. The second magnetic component is subjected to a pushing force (repulsive force) in the magnetic field formed by the first magnetic component, and this pushing force will cause the second magnetic component to move relative to the first magnetic component in the receiving cavity.

[0056] When the first magnetic component is configured as a coil, the second magnetic component can also be configured as a coil. In the first energized state, that is, when current is applied to each of the first and second magnetic components, the first magnetic component can form a first magnetic field, and the second magnetic component can cooperate with the first magnetic field formed by the first magnetic component. The second magnetic component is subjected to a pushing force (repulsive force) in the magnetic field formed by the first magnetic component, and this pushing force will cause the second magnetic component to move relative to the first magnetic component in the receiving cavity.

[0057] According to an embodiment of this disclosure, the storage tube 100, by providing a cooperating first magnetic element and a second magnetic element in the storage cavity, allows the stylus 2 to be easily removed when connected to the pen holder 5 at the insertion position. By applying current to the coil (i.e., in a first energized state), the second magnetic element moves the pen holder 5 and the stylus 2 from the insertion position to the ejection position. Since the pen holder 5 and the stylus 2 can be automatically moved from the insertion position to the ejection position, the portion of the stylus 2 exposed in the storage cavity at the insertion position can be reduced, or the stylus 2 can be completely contained within the storage cavity. This avoids the risk of the stylus 2 falling due to accidental contact, thus achieving safe storage of the stylus 2.

[0058] Therefore, the storage tube 100 according to the embodiments of this disclosure has the advantages of making the stylus 2 easy to access and enabling the stylus 2 to be safely stored.

[0059] The following is for reference. Figures 1-16 The present disclosure describes in detail the storage tube 100, stylus assembly 200, protective case 300, and tablet computer assembly 900 according to embodiments thereof.

[0060] like Figure 1As shown, this disclosure provides a tablet computer assembly 900. The tablet computer assembly 900 according to this disclosure includes a protective case 300, a tablet computer 92, and a keyboard 91.

[0061] like Figure 2 As shown, the protective sleeve 300 according to an embodiment of the present disclosure includes a support plate 31 and a storage tube 100. The support plate 31 has a first connecting portion 311 and a second connecting portion 312. The first connecting portion 311 and the second connecting portion 312 are connected to the storage tube 100. The storage tube 100 is the storage tube 100 according to an embodiment of the present disclosure. Optionally, the first connecting portion 311 and the second connecting portion 312 can be connected to the storage tube 100 through a flexible connecting portion 313. The flexible connecting portion 313 can be made of PU (polyurethane).

[0062] According to the embodiments of this disclosure, the protective case 300 can be detachably connected to the tablet computer 92 via the first connecting part 311 and detachably connected to the keyboard 91 via the second connecting part 312, thereby enabling the tablet computer 92, the storage tube 100, and the keyboard 91 to be used together, thus providing users with more convenient operation. Furthermore, since the protective case 300 includes the storage tube 100 according to the embodiments of this disclosure, the stylus 2 can be easily accessed and safely stored.

[0063] Therefore, the protective case 300 according to the embodiments of this disclosure has the advantages of providing users with more convenient operation, enabling safe storage of the stylus 2 and convenient access to the stylus 2.

[0064] The tablet computer 92 is detachably connected to the first connecting portion 311 of the protective case 300. The keyboard 91 is detachably connected to the second connecting portion 312 of the protective case 300. The tablet computer assembly 900 according to this embodiment combines the tablet computer 92, the storage tube 100, and the keyboard 91 for use, providing users with more convenient operation. Furthermore, since the tablet computer assembly 900 includes the protective case 300, which includes the storage tube 100, the stylus 2 can be easily accessed and safely stored.

[0065] Therefore, the tablet computer component 900 according to the embodiments of this disclosure has advantages such as providing users with more convenient operation, easy access to the stylus 2, and safe storage of the stylus 2.

[0066] Specifically, such as Figure 1 and Figure 2As shown, the first connecting part 311 includes a main support plate 3111 and a secondary support plate 3112. One end of the secondary support plate 3112 is rotatably connected to the main support plate 3111, so that the secondary support plate 3112 can rotate relative to the main support plate 3111 by a predetermined angle, thereby achieving vertical support for the tablet computer 92. This allows the tablet computer 92 to be placed at an angle on the main support plate 3111 for the user to view.

[0067] like Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, the storage tube 100 of the tablet computer assembly 900 according to an embodiment of this disclosure includes an electrical connector 33 (e.g., a spring pin). In use, the electrical connector 33 is electrically connected to the tablet computer 92 and the keyboard 91. The electrical connector 33 is used to transmit data between the tablet computer 92 and the keyboard 91 and to transmit external current to power the tablet computer 92. Alternatively, the electrical connector 33 is used to transmit data between the tablet computer 92 and the keyboard and to transmit current from the tablet computer 92 to power the keyboard 91.

[0068] An electrical connector 33 is provided on the storage tube 100. When the tablet computer 92 and keyboard 91 are connected to the protective cover 300, the contacts on the tablet computer 92 can easily contact the electrical connector 33 on the storage tube 100, thereby facilitating data communication between the tablet computer 92 and the keyboard 91, and enabling the tablet computer 92 to supply power to the keyboard 91 or an external power source to supply power to the tablet computer 92.

[0069] Optionally, the electrical connector 33 is electrically connected to the flexible circuit board 34 within the protective sleeve 300. At least a portion of the flexible circuit board 34 is disposed within the flexible connection portion 313. The flexible circuit board 34 is electrically connected to the keyboard 91 connected to the protective sleeve 300, thereby enabling the keyboard 91 to be electrically connected to the electrical connector 33.

[0070] like Figure 11 As shown, the end of the storage tube 100 is provided with a charging port (e.g., a USB charging port) 32 for connecting to an external power source. The charging port 32 is electrically connected to the electrical connector 33. Therefore, when the tablet computer 92 is placed on the protective case 300, the tablet computer 92 rests on the storage tube 100 and the first connecting part 311, connecting to an external power source through the charging port 32, and the electrical connector 33 connects to contacts on the tablet computer 92, enabling power and charging of the tablet computer 92 through the charging port 32 and the electrical connector 33. This allows for convenient charging of the tablet computer 92 when it is fixed in place on the protective case 300, avoiding the messy and disorganized charging circuit caused by directly charging the tablet computer 92 while it is placed on the protective case 300. It also allows for greater versatility in the functionality of the protective case 300.

[0071] It should be noted that when the tablet computer 92 is charged through the charging port 32, the external power source at the charging port 32 can also supply power to the keyboard 91.

[0072] like Figure 1 As shown, the first connecting portion 311 is provided with a sixth magnetic element 301 for attracting the tablet computer 92. This allows the tablet computer 92 to be more securely attached to the first connecting portion 311, thus preventing the tablet computer 92 from sliding on the first connecting portion 311. Meanwhile, the second connecting portion 312 is also provided with a seventh magnetic element (not shown) for attracting the keyboard 91. This allows the keyboard 91 to be more securely connected to the second connecting portion 312.

[0073] like Figure 9 As shown, the stylus assembly 200 according to an embodiment of the present disclosure includes a storage cylinder 100 and a stylus 2. The storage cylinder 100 is the storage cylinder 100 according to an embodiment of the present disclosure. The stylus 2 is detachably engaged with a pen holder 5 so that the pen holder 5 can move the stylus 2, and the stylus 2 can also be detached from the pen holder 2 under the action of external force. A portion of the stylus 2 in the pop-out position extends out of the storage cavity, thereby allowing the stylus 2 to be easily removed from the storage cylinder 100.

[0074] When the stylus 2 is connected to the pen holder 5 located in the insertion position, by passing current through the coil, the second magnetic component, under the action of the first magnetic field formed by the first magnetic component, can automatically move the pen holder 5 and the stylus 2 from the insertion position to the ejection position, so as to facilitate the removal of the stylus 2. Since the stylus 2 can be automatically moved from the insertion position to the ejection position, the portion of the stylus 2 exposed in the storage cavity at the insertion position can be reduced, or the stylus 2 can be completely placed in the storage cavity. This avoids the risk of the stylus 2 falling out due to accidental contact, and thus achieves safe storage of the stylus 2.

[0075] Therefore, the stylus assembly 200 according to the embodiments of this disclosure has advantages such as being able to safely store the stylus 2 and making the stylus 2 easy to access.

[0076] Optionally, the pen holder 5 is provided with an elastic part (not shown in the figure), which has a socket, and the stylus 2 can be detachably engaged with the socket. For example, a soft rubber that can provide a wrapping force to the stylus 2 is provided at the position on the pen holder 5 where it contacts the stylus 2. Providing the soft rubber in the pen holder 5 is convenient and can provide a large wrapping force to the stylus 2, thereby providing a large frictional force to the stylus 2, which facilitates the movement of the stylus 2 by the pen holder 5.

[0077] like Figures 3-6As shown, the stylus 2 further includes a third magnetic element 21. The storage tube 100 further includes a fourth magnetic element 11 and a fifth magnetic element 12. When the stylus 2 is in the pop-out position, the third magnetic element 21 and the fourth magnetic element 11 attract each other. When the stylus 2 is in the insertion position, the third magnetic element 21 and the fifth magnetic element 12 attract each other.

[0078] In the pen ejection structure of related technologies, after the pen is ejected, the user needs to hold the pen in time, otherwise the pen may fall under certain circumstances, causing damage to the pen.

[0079] According to the embodiments of this disclosure, the stylus assembly 200 prevents the stylus 2 from falling out when it is in the pop-up position by attracting the third magnetic element 21 of the stylus 2 in the pop-up position with the fourth magnetic element 11 of the storage tube 100. In other words, even if the user does not pick up the stylus 2 in time after it pops out, the fourth magnetic element 11 will still hold it in place. Therefore, even if the storage tube 100 (stylus 2) tilts or the stylus 2 is accidentally touched, the stylus 2 will not fall out, thus achieving safe storage of the stylus 2. Furthermore, by attracting the third magnetic element 21 of the stylus 2 in the insertion position with the fifth magnetic element 12, the stylus 2 in the insertion position is firmly connected to the storage tube 100, thereby enabling the stylus assembly 200 to safely store the stylus 2 in any scenario and making the stylus assembly 200 easy to move and carry.

[0080] Specifically, such as Figures 3-6 As shown, each of the third magnetic element 21, the fourth magnetic element 11, and the fifth magnetic element 12 is a magnet. Thus, the attraction between the magnets provides a stronger attraction, allowing the stylus 2 to be more firmly attached to the storage cavity of the storage tube 100, preventing it from falling out.

[0081] Furthermore, depending on the specific structure of the storage tube 100 and the stylus 2, in this embodiment, the third magnetic element 21 can be set to three, with the three third magnetic elements 21 spaced apart inside the stylus 2. The fifth magnetic element 12 can be set to two, with the two fifth magnetic elements 12 spaced apart on the tube body 1. The stylus 2 in the pop-out position is attracted by one third magnetic element 21 and the fourth magnetic element 11. The stylus 2 in the insertion position can be attracted by two third magnetic elements 21 and two fifth magnetic elements 12 in a one-to-one correspondence.

[0082] Therefore, the stylus 2 in the pop-out position can be attracted to the storage cavity by a set of magnets, and the stylus 2 in the insertion position can be attracted to the storage cavity by two sets of magnets. This increases the attraction between the stylus 2 in the insertion position and the storage tube 100, making the stylus 2 in the insertion state firmly connected within the storage tube 100 and facilitating the movement and transportation of the stylus assembly 200. At the same time, because the attraction between the stylus 2 in the pop-out position and the storage tube 100 is relatively weak, it can both prevent the stylus 2 from falling out of the storage tube 100 and make it convenient for the user to remove the stylus 2.

[0083] like Figures 3-6 As shown, the storage tube 100 also includes a charging transmitter module 13. When the stylus 2 is in the inserted position, the charging transmitter module 13 cooperates with the charging receiver module 22 of the stylus 2 to charge the stylus 2. This enables the stylus assembly 200 to have the function of charging the stylus 2.

[0084] like Figures 3-6 As shown, the storage tube 100 also includes a Hall switch 14. The Hall switch 14 is used to detect the position state of the stylus 2 and control the opening and closing of the charging transmitter module 13 according to the detection result.

[0085] For example, when the stylus 2 is in the inserted position, the N-pole of a third magnetic element 21 of the stylus 2 is directly opposite the Hall switch 14 in the radial direction of the stylus 2. The magnetic flux of the third magnetic element 21 reaches the sensing threshold of the Hall switch 14, triggering the Hall switch 14. At this time, the Hall switch 14 controls the charging transmitter module 13 to open, thereby enabling the charging transmitter module 13 to charge the stylus 2. In other words, as long as the stylus 2 is in the inserted position in the storage cavity and the stylus 2 is not fully charged, the storage tube 100 can charge the stylus 2.

[0086] When the stylus 2 is in the pop-up position, the N-terminus of the third magnetic element 21 of the stylus 2 is offset from the Hall switch 14 in the radial direction of the stylus 2. The magnetic flux of the third magnetic element 21 does not meet the sensing threshold requirement of the Hall switch 14, so the Hall switch 14 is turned off. At this time, the Hall switch 14 controls the charging transmitter module 13 to turn off, so the wireless charging transmitter 14 cannot charge the stylus 2.

[0087] According to the embodiments of the present disclosure, the stylus assembly 200 controls whether the charging transmitter module 13 charges the stylus 2 via the Hall switch 14, which can prevent the charging transmitter module 13 from being in standby mode all the time, thereby reducing the power consumption of the charging transmitter module 13.

[0088] Specifically, such as Figures 3-6As shown, in this embodiment, the third magnetic element 21 of the stylus 2 can cooperate with the Hall switch 14 when the stylus 2 is in the inserted position. When the stylus 2 is in the ejected position, the third magnetic element 21 can be attracted with the fourth magnetic element 1. This reduces the number of magnetic elements provided in the stylus 2, making the structure of the stylus 2 simpler.

[0089] Optionally, the tablet computer 92 includes an eighth magnetic element (not shown) that cooperates with the fourth magnetic element 11 and / or the fifth magnetic element 12. Thus, when the tablet computer is supported on the storage tube 100, the fourth magnetic element 11 and / or the fifth magnetic element 12 can provide a magnetic attraction to the tablet computer, thereby enabling the tablet computer to be supported more stably on the storage tube 100.

[0090] The following is for reference. Figures 10-13 A detailed description of one embodiment of the storage tube according to the present disclosure.

[0091] As shown in the figure Figures 10-13 As shown, the storage tube 100 according to an embodiment of this disclosure includes a tube body 1, a first magnetic element 74, a second magnetic element 73, and a pen holder 5. The tube body 1 has a storage cavity (not shown in the figure). The first magnetic element 74 is used to form a first magnetic field and is disposed in the storage cavity. The second magnetic element 73 is a coil. The second magnetic element 73 is movably disposed in the storage cavity between a retracted position and a delivery position.

[0092] To make the technical solution of this application easier to understand, the following description uses the movement of the second magnetic component 73 in the left-right direction between the retracted position and the extended position as an example. Wherein, the left-right direction is as follows... Figure 12 and Figure 13 As indicated by arrow A, the second magnetic element 73 moves from the retracted position to the right to the delivery position and from the delivery position to the left to the retracted position.

[0093] The pen holder 5 is connected to the second magnetic element 73. For example, the left end of the pen holder 5 is connected to a support member on which the second magnetic element (coil) 73 is wound. Specifically, as shown... Figures 11-13 As shown, the storage tube 100 according to an embodiment of this disclosure further includes a movable rod 71. A first end (e.g., the left end) of the movable rod 71 is connected to a second magnetic element 73, and a second end (e.g., the right end) of the movable rod 71 is connected to a pen holder 5. This facilitates the connection between the pen holder 5 and the second magnetic element 73. Optionally, the left end of the pen holder 5 is connected to the movable rod 71 via a fastener, making the connection convenient.

[0094] In the first energized state, that is, when current is applied to the second magnetic element 73, the second magnetic element 73 is subjected to Ampere force in the first magnetic field formed by the first magnetic element 74. This Ampere force causes the second magnetic element 73 to move to the right relative to the first magnetic element 74 so as to move from the retracted position to the ejected position. The second magnetic element 73 drives the pen holder 5 from the insertion position to the ejected position.

[0095] In the second energized state, that is, when a reverse current is applied to the second magnetic element 73, the second magnetic element 73 is subjected to an Ampere force in the first magnetic field formed by the first magnetic element 74. This Ampere force causes the second magnetic element 73 to move to the left relative to the first magnetic element 74 from the delivery position to the retraction position.

[0096] In other words, by changing the direction of the current flowing into the second magnetic element 73, the direction of the Ampere force on the second magnetic element 73 can be changed, thereby changing the direction of movement of the second magnetic element 73 in the receiving cavity, so that the second magnetic element 73 can move between the retracted position and the delivery position.

[0097] It should be noted that the left end of the cylinder 1 is closed, while the right end of the cylinder 1 is open, so that the stylus 2 can be pulled out from the right end of the cylinder 1.

[0098] like Figure 12 and Figure 13 As shown, a first magnetic element 74 is disposed within the receiving cavity. The first magnetic element 74 includes an inner magnetic element 742 and an outer magnetic element 741. The first magnetic poles of the inner magnetic element 742 and the outer magnetic element 741 are arranged opposite to each other, and the polarity of the first magnetic poles of the inner magnetic element 742 and the outer magnetic element 741 is opposite. A second magnetic element 73 is wound between the first magnetic poles of the inner magnetic element 742 and the outer magnetic element 741. This facilitates the formation of the first magnetic field between the first magnetic poles of the inner magnetic element 742 and the outer magnetic element 741. The second magnetic element 73, wound within this first magnetic field, can be easily subjected to an Ampere force to move the pen holder 5 and the stylus 2.

[0099] like Figures 11-13 As shown, the storage tube 100 according to an embodiment of this disclosure further includes a cantilever shaft 75 disposed within the tube body 1. An external magnetic element 741 is disposed on the inner circumferential surface of the tube body 1. An internal magnetic element 742 is disposed on the outer circumferential surface of at least a portion 751 of the cantilever shaft 75. This allows the external magnetic element 741 and the internal magnetic element 742 to be stably and reliably installed within the storage cavity.

[0100] Optionally, such as Figures 11-13As shown, the storage tube 100 according to an embodiment of this disclosure further includes a fixing tube 7. The fixing tube 7 is disposed within the storage cavity, and the axial direction of the fixing tube 7 and the axial direction of the tube body 1 are both in the left-right direction. An external magnetic element 741 is disposed on the inner circumferential surface of the fixing tube 7. At least a portion 751 of the cantilever shaft 75 extends into the fixing tube 7. An internal magnetic element 742 is disposed on the outer circumferential surface of the at least a portion 751 of the cantilever shaft 75. Thus, the external magnetic element 741 can be assembled into the fixing tube 7 first, and then the external magnetic element 741 and the fixing tube 7 can be assembled together in the storage cavity, which is convenient for assembly.

[0101] A fixing cylinder 7 is installed inside the storage cavity. The right end face of the fixing cylinder 7 also facilitates the limiting of the pen holder 5, thereby enabling the pen holder 5 to have a stable retracted position. In addition, a part of the movable rod 71 is slidably connected inside the fixing cylinder 7 so that the fixing cylinder 7 guides the movable rod 71.

[0102] like Figure 12 and Figure 13 As shown, there are multiple external magnetic components 741, which are spaced apart along the circumference of the cylinder 1 on its inner circumferential surface. There are also multiple internal magnetic components 742, which are spaced apart along the circumferential surface of the cantilever shaft 75 on its outer circumferential surface. The multiple external magnetic components 741 and multiple internal magnetic components 742 correspond one-to-one in the inner and outer directions. This allows the first magnetic component 74 to provide a stronger magnetic field, resulting in a larger Ampere force on the second magnetic component 73, thus making it easier for the second magnetic component 73 to move the pen holder 5 and the stylus 2 within the storage cavity.

[0103] The shapes of the second magnetic element 73, the inner circumferential surface of the fixed cylinder 7, and the outer circumferential surface of the cantilever shaft 75 are adapted to each other. For example, in this embodiment, the shapes of the second magnetic element 73, the inner circumferential surface of the fixed cylinder 7, and the outer circumferential surface of the cantilever shaft 75 are all quadrangular prisms. This maximizes the utilization of the space of the magnetic field formed between the inner magnetic element 742 and the outer magnetic element 741, allowing more turns of the second magnetic element 73 to be arranged in the first magnetic field within a certain space. This results in a greater Ampere force on the second magnetic element 73, making it easier for the second magnetic element 73 to move the pen holder 5 and the stylus 2 within the storage cavity.

[0104] like Figures 11-13As shown, the storage tube 100 according to an embodiment of this disclosure also includes a power supply unit 72. The power supply unit 72 is disposed within the storage cavity. The power supply unit 72 is electrically connected to the second magnetic element 73 to switchably supply one of a first current and a second current to the second magnetic element 73. The directions of the first current and the second current are opposite. This allows for convenient supply of currents in opposite directions to the second magnetic element 73. The power supply unit 72 includes a power switch (not shown) controlling the coil (second magnetic element 73) to be in a de-energized state, a first energized state, and a second energized state.

[0105] When the storage tube 100 is used in conjunction with a tablet computer, the power supply unit 72 may include circuitry that adjusts the magnitude of the external input current. The power switch may be a small program running on the tablet computer that controls this circuitry.

[0106] Of course, the power supply component 72 can also include power components such as battery 782. For example Figure 12 As shown, the power supply unit 72 includes a battery 782 and a circuit board 721 (e.g., a PCB board). The battery 782 is connected to one end of the circuit board 721. The cantilever shaft 75 is connected to the other end of the circuit board 721. The circuit board 721 is connected to the second magnetic component 73 via a wavy wire 76, so that the second magnetic component 73 does not pull the circuit board 721 when moving between the retracted and extended positions. The circuit board 721 can change the direction and magnitude of the current supplied to the second magnetic component 73, so that the current supplied by the battery 782 to the second magnetic component 73 meets the usage requirements of the second magnetic component 73. When the power supply unit 72 includes the battery 782, the power supply switch can be a physical switch located at a certain position on the cylinder 1.

[0107] The following is for reference. Figure 10 , Figures 14-16 A further embodiment of the storage tube according to the present disclosure is described in detail.

[0108] As shown in the figure Figure 10 , Figures 14-16 As shown, the storage tube 100 according to an embodiment of this disclosure includes a tube body 1, a first magnetic element 85, a second magnetic element 83, and a pen holder 5. The tube body 1 has a storage cavity. The first magnetic element 85 is a coil. The coil is disposed in the storage cavity. The second magnetic element 83 is movably disposed in the storage cavity between a retracted position and a delivery position.

[0109] To make the technical solution of this application easier to understand, the following description uses the movement of the second magnetic component 83 in the left-right direction between the retracted position and the extended position as an example. Wherein, the left-right direction is as follows... Figure 9 and Figure 10 As indicated by arrow A, the second magnetic element 83 moves from the retracted position to the right to the delivery position, and from the delivery position to the left to the retracted position.

[0110] The pen holder 5 is connected to the second magnetic component 83. Specifically, as shown... Figures 14-16 As shown, the storage tube 100 according to an embodiment of this disclosure further includes a movable rod 81. A first end (e.g., the left end) of the movable rod 81 is connected to a second magnetic element 83, and a second end (e.g., the right end) of the movable rod 81 can be connected to a pen holder 5. This facilitates the connection between the pen holder 5 and the second magnetic element 83. Optionally, the left end of the pen holder 5 is connected to the movable rod 81 via a fastener, making the connection convenient.

[0111] Optionally, the interior of the movable rod 81 is designed to be hollow, thereby reducing the weight of the storage tube 100 and making it more convenient to carry.

[0112] In the first energized state, that is, when current is applied to the second magnetic element 83, the second magnetic element 83 is subjected to a repulsive force in the first magnetic field formed by the first magnetic element 85. This repulsive force causes the second magnetic element 83 to move to the right relative to the first magnetic element 85 so as to move from the retracted position to the ejected position. The second magnetic element 83 drives the pen holder 5 from the insertion position to the ejected position.

[0113] In the second energized state, that is, when a reverse current is applied to the second magnetic element 83, the second magnetic element 83 is subjected to an attractive force in the first magnetic field formed by the first magnetic element 85. This attractive force causes the second magnetic element 83 to move to the left relative to the first magnetic element 85 from the delivery position to the retraction position.

[0114] In other words, by changing the direction of the current flowing through the first magnetic element 85, the direction of the force on the second magnetic element 83 can be changed, thereby changing the direction of movement of the second magnetic element 83 in the receiving cavity, so that the second magnetic element 83 can move between the retracted position and the delivery position.

[0115] It should be noted that the left end of the cylinder 1 is closed, while the right end of the cylinder 1 is open, so that the stylus can be pulled out from the right end of the cylinder 1.

[0116] like Figure 10 , Figures 14-16As shown, the storage tube 100 according to an embodiment of this disclosure further includes a fixed tube 8. The fixed tube 8 is disposed within the storage cavity. The axial direction of both the tube body 1 and the fixed tube 8 is left-right. A first magnetic element 85 is disposed within the fixed tube 8. A second magnetic element 83 is movably disposed within the fixed tube 8 between a retracted position and a delivery position. A portion of a movable rod 81 is movably disposed within the fixed tube 8 so that a first end of the movable rod 81 is connected to the second magnetic element 83, and the fixed tube 8 also guides the movable rod 81. In other words, the movable rod 81 is movably disposed relative to the fixed tube 8, and a portion of the movable rod 81 is located within the fixed tube 8. This allows the first magnetic element 85, the second magnetic element 83, and the movable rod 81 to be first assembled within the fixed tube 8, and then the first magnetic element 85, the first magnetic element 85, the movable rod 81, and the fixed tube 8 to be assembled as a whole within the storage cavity, facilitating assembly. Furthermore, the fixed tube 8 is disposed within the storage cavity, and its end face also facilitates the positioning of the pen holder 5.

[0117] Preferably, the second magnetic element 83 is a magnet. Therefore, on the one hand, the magnet's strong magnetism ensures that the attractive and repulsive forces acting on the second magnetic element 83 are sufficient to move the pen holder 5 and the stylus 2. On the other hand, the magnet does not require electricity to generate magnetism, saving energy.

[0118] like Figures 14-16 As shown, the storage tube 100 according to an embodiment of this disclosure further includes a power supply component 82. The power supply component 82 is disposed within the storage cavity. The power supply component 82 is electrically connected to a first magnetic component 85 to switchably supply one of a first current and a second current to the first magnetic component 85, the directions of the first current and the second current being opposite. This facilitates the supply of currents in opposite directions to the coil, thereby generating two first magnetic fields of opposite polarities within the first magnetic component 85. The power supply component 82 includes a power switch (not shown) for controlling the first magnetic component 85 to be in a de-energized state, a first energized state, and a second energized state.

[0119] When the storage tube 100 is used in conjunction with the tablet computer 92, the power supply unit 82 may include circuitry that adjusts the magnitude of the external input current. The power switch may be a small program running on the tablet computer 92 that controls this circuitry.

[0120] Of course, the power supply component 82 can also include power components such as battery 822. For example Figure 15 and Figure 16As shown, the power supply unit 82 includes a battery 822 and a circuit board 821 (e.g., a PCB board). The battery 822 is connected to one end of the circuit board 821, and the coil is connected to the other end of the circuit board 821. Thus, the circuit board 821 can change the direction and magnitude of the current flowing into the coil, ensuring that the current supplied by the battery 822 meets the coil's usage requirements. When the power supply unit 82 includes a battery 822, the power switch can be a physical switch located at a certain position on the cylinder 1.

[0121] like Figure 9 As shown, the storage tube 100 according to an embodiment of this disclosure further includes a protective shell 84. The protective shell 84 is disposed on a circuit board 821, and a protective cavity is defined between the protective shell 84 and the circuit board 821, and the coil is disposed within the protective cavity. This provides a mounting space with a certain rigidity for the coil, facilitating coil installation, and also preventing the coil from being compressed and deformed, which would affect the magnetic field generated in the coil.

[0122] like Figures 17-24 As shown, the storage tube 100 includes a tube body 1, an elastic element 62, a pen holder 61, and a limiting part. The tube body 1 has a storage cavity (not shown in the figure) with a stylus inlet and outlet, so that the stylus 2 can be inserted into and removed from the storage cavity through the stylus inlet and outlet. The elastic element 62 is provided on the tube body 1 and is connected to the pen holder 61.

[0123] The outer circumferential surface of the pen holder 61 has an annular groove 612, which has an extension position and a retraction position. The extension position is adjacent to the stylus inlet and outlet relative to the retraction position. The limiting part is connected to the cylinder 1 and fits within the annular groove 612. The pen holder 61 has a stop 615. When the pen holder 61 is in the insertion position, the stop 615 stops the limiting part to prevent it from sliding to the extension position, and the elastic member 62 is in a deformed state to push the pen holder 61 to the eject position.

[0124] In related technologies, a storage compartment for accommodating a stylus is provided on a tablet computer or on the tablet computer's accompanying keyboard. When the stylus is placed in the storage compartment, the compartment cannot automatically pop the stylus out, making it inconvenient to retrieve. Alternatively, when the stylus is placed in the storage compartment, too much of the stylus protrudes from the compartment, which, while convenient to retrieve, poses a risk of the stylus falling out due to accidental touch.

[0125] When the storage tube 100 according to the present disclosure is in use, when the pen holder 61 is in the insertion position, the stop part 615 stops the limiting part so that the limiting part and the annular sliding groove 612 of the pen holder 61 cannot move relative to each other, so that the pen holder 61 stays in the insertion position, and the stylus 2 connected to (placed) on the pen holder 61 can also stay in the insertion position, that is, the stylus 2 is placed in the storage cavity of the storage tube 100.

[0126] When you want to remove the stylus 2, you can apply an external force to the stop 615 so that the stop 615 no longer blocks the limiting part, and the limiting part no longer blocks the pen holder 61. Since the elastic member 62 is in a deformed state to push the pen holder 61 towards the pop-out position, the pen holder 61 will move from the insertion position to the pop-out position under the elastic force of the elastic member 62. At this time, the pen holder 61 is in the pop-out position, and due to the action of the elastic member 62, the pen holder 61 cannot automatically move from the pop-out position to the insertion position.

[0127] Understandably, when the stylus is connected to the pen holder 61 located at the insertion position, by applying an external force to the stop 615, the pen holder 61, under the elastic force of the elastic member 62, can move the stylus 2 from the insertion position to the ejection position, thus facilitating its removal. Since the stylus 2 can be moved from the insertion position to the ejection position, the portion of the stylus 2 exposed in the storage cavity can be reduced, or the stylus 2 can be completely contained within the storage cavity. This avoids the risk of the stylus 2 falling out due to accidental contact, thereby achieving safe storage of the stylus 2.

[0128] When the stylus 2 is connected to the pen holder 61 located in the pop-up position, pressing the pen holder 61 with the stylus 2 can move the pen holder 61 and the stylus 2 from the pop-up position to the insertion position.

[0129] Therefore, the storage tube 100 according to the embodiments of this disclosure has the advantages of making it convenient to take out the stylus 2 and safely storing the stylus 2.

[0130] Accordingly, the tablet computer component according to the embodiments of this disclosure has advantages such as providing users with more convenient operation, making it easy to pick up the stylus 2, and enabling the stylus 2 to be safely stored.

[0131] The stylus assembly 200 according to an embodiment of the present disclosure includes a storage tube 100 and a stylus 2. The stylus 2 is detachably connected to a pen holder 61. The stylus 2 is movably disposed along with the pen holder 61 between an insertion position and a pop-out position.

[0132] According to an embodiment of this disclosure, the stylus assembly 200 allows the stylus 2 to be detachably connected to the storage tube 100. When the stylus 2 is connected to the pen holder 61 located at the insertion position, pressing the stylus 2 moves both the pen holder 61 and the stylus 2 from the insertion position to the ejection position, facilitating easy removal of the stylus 2. Since the stylus 2 can be automatically moved from the insertion position to the ejection position, the portion of the stylus 2 exposed in the storage cavity can be reduced, or the stylus 2 can be completely contained within the storage cavity. This avoids the risk of the stylus 2 falling out due to accidental contact, thus enabling safe storage of the stylus 2.

[0133] When the stylus 2 is connected to the pen holder 6 located in the pop-up position, pressing the stylus 2 can automatically pull the pen holder 6 and the stylus 2 back from the pop-up position to the insertion position.

[0134] In this configuration, at least a portion of the stylus 2 in the insertion position is located within the storage cavity, while a portion of the stylus 2 in the pop-out position extends beyond the storage cavity. In other words, the stylus 2 in the insertion position can be entirely within the storage cavity or only partially protruding, thus avoiding the risk of accidental drop due to excessive protrusion when in the insertion position, thereby ensuring safe storage of the stylus 2. Simultaneously, the portion of the stylus 2 protruding beyond the storage cavity in the pop-out position extends further than that in the insertion position, facilitating easy retrieval.

[0135] Therefore, the stylus assembly 200 according to the embodiments of this disclosure has advantages such as being able to safely store the stylus 2 and making it convenient to retrieve the stylus 2.

[0136] Preferably, the pen holder 61 is provided with an elastic part (not shown in the figure), the elastic part having an insertion hole, and the stylus 2 can be disengaged and engaged with the insertion hole. For example, a soft rubber that can provide a wrapping force to the stylus 2 is provided at the position on the pen holder 61 where it contacts the stylus 2. Providing the soft rubber in the pen holder 61 is convenient and can provide a large wrapping force to the stylus, thereby providing a large frictional force to the stylus, so that the pen holder 61 can easily move the stylus 2 from the pop-out position to the insertion position.

[0137] To make the technical solution of this application easier to understand, the following description uses the left and right directions as an example. Wherein, the left and right directions are as follows... Figures 17-24 As shown by arrow A, the pen holder 61 moves from the insertion position to the pop-up position to the right, and from the pop-up position to the insertion position to the left.

[0138] A USB charging port 32 is provided on the left end face of the cylinder 1, and the right end of the cylinder 1 is open to form the stylus inlet and outlet, so that the stylus can be inserted into and removed from the storage cavity through the stylus inlet and outlet.

[0139] The elastic element 62 is located on the left side of the pen holder 61, and the right end of the elastic element 62 is connected to the pen holder 61. The elastic element 62 can be a spring in a compressed state.

[0140] The pen holder 61 is movably disposed within the receiving cavity in the left-right direction between an insertion position and a pop-out position, so that the stylus 2 connected to the pen holder 61 can move between the insertion position and the pop-out position. The outer peripheral surface of the pen holder 61 has an annular groove 612. The annular groove 612 includes a delivery section 6121 and a retraction section 6122. The first end 61211 (right end) of the delivery section 6121 is adjacent to the stylus inlet / outlet in the left-right direction relative to the second end 61212 (left end) of the delivery section 6121. The third end 61221 (right end) of the retraction section 6122 is adjacent to the stylus inlet / outlet in the left-right direction relative to its fourth end 61222 (left end). The second end 61212 and the fourth end 61222 are connected in the delivery position.

[0141] like Figure 18 , Figure 19 and Figure 24 As shown, the annular groove 612 further includes a first transition section 6123 and a second transition section 6124. The fifth end 61231 of the first transition section 6123 is adjacent to the stylus inlet / outlet in a predetermined direction (left-right direction) relative to the sixth end 61232 of the first transition section 6123. The fifth end 61231 and the first end 61211 are connected at the first transition position.

[0142] The seventh end 61241 of the second transition section 6124 is adjacent to the stylus inlet / outlet in a predetermined direction (left-right direction) relative to its eighth end 61242. The seventh end 61241 and the third end 61221 are connected at the second transition position. The eighth end 61242 and the sixth end 61232 are connected at the retracted position. The portion of the pen holder 61 located between the delivery section 6121 and the first transition section 6123 constitutes the stop portion 615.

[0143] Therefore, when the pen holder 61 is in the insertion position, the stop part 615 stops the limiting part so that the limiting part and the annular sliding groove 612 of the pen holder 61 cannot move relative to each other, that is, it prevents the limiting part from entering the first transition section 6123, so that the pen holder 61 stays in the insertion position, and the stylus 2 connected to (placed) on the pen holder 61 can also stay in the insertion position, that is, the stylus 2 is placed in the storage cavity of the storage tube 100.

[0144] When you want to remove the stylus 2, press the pen holder 61 with the stylus 2, which will cause the limiting part to enter the first transition section 6123. As a result, the pen holder 61 moves to the left from the insertion position to the first transition position under the action of external force (by the pressing force applied by the stylus 2), that is, the limiting part moves to the right relative to the pen holder 61 so that it can slide from the sixth end 61232 to the fifth end 61231. At this time, the pen holder 61 is pressed all the way down.

[0145] Since the fifth end 61231 is connected to the first end 61211, the limiting part moves to the fifth end 61231. Because the elastic member 62 is in a deformed state to push the pen holder 61 to the pop-out position, when the stylus is released, the pen holder 61, under the elastic force of the elastic member 62, will move from the first transition position to the right to the pop-out position, that is, the limiting part moves to the left relative to the pen holder 61 so as to slide from the first end 61211 to the second end 61212. At this time, the pen holder 61 is in the pop-out position, and due to the action of the elastic member 62, the pen holder 61 cannot automatically move from the pop-out position to the insertion position.

[0146] Since the second end 61212 is connected to the fourth end 61222, if the stylus 2 is pressed on the pen holder 61, the limiting part can move from the second end 61212 to the fourth end 61222 to enter the retracting section 6122. Under the action of external force (the pressing force applied by the stylus 2), the pen holder 61 moves from the pop-up position to the left to the second transition position, that is, the limiting part moves to the right relative to the pen holder 61 so as to slide from the fourth end 61222 to the third end 61221. At this time, the pen holder 61 is pressed all the way down.

[0147] Since the third end 61221 is connected to the seventh end 61241, the limiting part moves to the seventh end 61241. At this time, when the stylus is released, the pen base 61 will move to the right from the second transition position to the insertion position under the elastic force of the elastic member 62, that is, the limiting part moves to the left relative to the pen base 61 so as to slide from the seventh end 61241 to the eighth end 61242.

[0148] Since the eighth end 61242 is connected to the sixth end 61232, the limiting part slides to the sixth end 61232 of the first transition section 6123. Since the stop part 615 stops the limiting part so that the limiting part and the annular groove 612 of the pen holder 61 cannot move relative to each other, that is, to prevent the limiting part from entering the first transition section 6123, the pen holder 61 can be kept in the insertion position.

[0149] By repeating the above process, pressing the stylus 2 once moves the pen holder 61 and the stylus 2 from the pop-up position to the insertion position. Pressing the stylus 2 again moves the pen holder 61 and the stylus 2 from the insertion position to the pop-up position. This cycle repeats, making it easier to retrieve the stylus 2 and store it safely.

[0150] like Figures 17-23As shown, the cylinder 1 includes a main body and a fixed cylinder 6. The main body has the storage cavity, and the fixed cylinder 6 is disposed in the storage cavity. The axial direction of the fixed cylinder 6 is the same as the preset direction (left-right direction). The pen holder 61 is provided with a guide groove 613 extending in the left-right direction, and the inner circumferential surface of the fixed cylinder 6 is provided with a guide protrusion 64 that cooperates with the guide groove 613, thereby enabling the pen holder 61 to move more accurately in the preset direction (left-right direction).

[0151] In this configuration, at least a portion of the pen holder 61 in the insertion position is located within the fixed cylinder 6, while a portion of the pen holder 61 in the pop-out position extends out of the fixed cylinder 6. Each of the limiting part and the elastic member 62 is connected to the fixed cylinder 6. This allows the limiting part, the elastic member 62, and the pen holder 61 to be first assembled within the fixed cylinder 6, and then the limiting part, the elastic member 62, the pen holder 61, and the fixed cylinder 6 to be assembled as a whole within the storage cavity, facilitating assembly.

[0152] Preferably, the bottom wall surface of the fourth end 61222 is located inside the bottom wall surface of the second end 61212. That is, the bottom wall surface of the fourth end 61222 is concave inward relative to the bottom wall surface of the second end 61212. This gives the bottom wall surface of the annular groove 612 a stepped portion that prevents the limiting part from moving from the fourth end 61222 to the second end 61212. Thus, when the pen holder 61 is in the pop-up position, pressing the pen holder 61 in the pop-up position with the stylus 2 can more reliably ensure that the limiting part can only slide along the retractable section 6122 from the fourth end 61222 to the third end 61221 when moving relative to the pen holder 61, thereby reliably ensuring that pressing the pen holder 61 once moves the pen holder 61 from the pop-up position to the insertion position.

[0153] like Figure 19 As shown, the bottom wall surface of the first end 61211 is located inside the bottom wall surface of the fifth end 61231, meaning that the bottom wall surface of the first end 61211 is concave inward relative to the bottom wall surface of the fifth end 61231. This gives the bottom wall surface of the annular groove 612 a stepped portion that prevents the limiting part from moving from the first end 61211 to the fifth end 61231. Therefore, when the stylus is released, the limiting part can reliably slide along the delivery section 6121, thereby ensuring more reliable and accurate reciprocating movement of the pen holder 61 between the pop-up position and the insertion position.

[0154] like Figure 19As shown, the bottom wall surface of the seventh end 61241 is located inside the bottom wall surface of the third end 61221, meaning that the bottom wall surface of the seventh end 61241 is concave inward relative to the bottom wall surface of the third end 61221. This gives the bottom wall surface of the annular groove 612 a stepped portion that prevents the limiting part from moving from the seventh end 61241 to the third end 61221. Therefore, when the stylus is released, the limiting part can reliably slide along the second transition section 6124, thereby ensuring more reliable and accurate reciprocating movement of the pen holder 61 between the pop-up position and the insertion position.

[0155] like Figure 19 As shown, the bottom wall surface of the sixth end 61232 is located inside the bottom wall surface of the eighth end 61242, meaning that the bottom wall surface of the sixth end 61232 is concave inward relative to the bottom wall surface of the eighth end 61242. This results in the bottom wall surface of the annular groove 612 having a stepped portion that prevents the limiting part from moving from the sixth end 61232 to the eighth end 61242. Therefore, when the pen holder 61 is in the inserted position, pressing the stylus reliably ensures that the limiting part slides along the first transition section 6123, thereby ensuring more reliable and accurate reciprocating movement of the pen holder 61 between the pop-out position and the inserted position.

[0156] Optionally, the first transition segment 6123 and the second transition segment 6124 form a V-shape. In other words, the first transition segment 6123 and the second transition segment 6124 constitute a V-shaped transition segment. This allows the limiting block to slide more smoothly in the first transition segment 6123 and the second transition segment 6124.

[0157] Optionally, such as Figure 19 As shown, the annular groove 612 is heart-shaped. This not only allows the first transition section 6123, the delivery section 6121, the retraction section 6122, and the second transition section 6124 to be generally arc-shaped, making the transition between these sections smoother, thus improving the structural strength of the pen holder 61 and the annular groove 612 on it, but also allows the limiting block to slide more smoothly in the first transition section 6123 and the second transition section 6124.

[0158] Specifically, such as Figure 19 As shown, a portion of the outer peripheral surface of the pen holder 61 is configured as a plane 611, on which the first transition section 6123, the second transition section 6124, the feed section 6121, and the retraction section 6122 are disposed. This not only reduces the machining difficulty of the annular groove 612, but also makes it easier for the limiting part to cooperate with each of the first transition section 6123, the second transition section 6124, the feed section 6121, and the retraction section 6122.

[0159] like Figure 18 , Figure 22and Figure 24 As shown, the storage tube 100 according to an embodiment of this disclosure further includes a pop-out rod 63. The pop-out rod 63 includes a rod body 631, a first bent section 632, and a second bent section 633.

[0160] The elastic element 62 is a helical spring. The rod body 631 contacts the inner ring of the elastic element 62, and is located between the elastic element 62 and the bottom wall of the annular groove 612 in the inward and outward directions. Each of the first bent segment 632 and the second bent segment 633 is connected to the rod body 631. The first bent segment 632 is adjacent to the stylus inlet / outlet in a predetermined direction (left-right direction) relative to the second bent segment 633. The second bent segment 633 is rotatably connected to the cylinder 1 to ensure that the first bent segment 632 slides smoothly along the annular groove 612. At least a portion of the first bent segment 632 fits within the annular groove 612, and at least a portion of the first bent segment 632 constitutes a limiting portion.

[0161] When at least a portion of the first bent section 632 engages within the annular groove 612 and moves along the annular groove 612, the inner ring of the elastic member 62 exerts a certain clamping force on the rod 631 due to the contact between the rod 631 and the inner ring of the elastic member 62. This allows the limiting portion formed by at least a portion of the first bent section 632 to always contact the bottom wall surface of the annular groove 612 (i.e., the bottom wall surface of the first transition section 6123, the bottom wall surface of the delivery section 6121, the bottom wall surface of the retraction section 6122, and the bottom wall surface of the second transition section 6124). This prevents the ejector rod 63 from moving outward and disengaging from the bottom wall surface, thereby ensuring that the pen holder 61 reciprocates more reliably between the ejection position and the insertion position.

[0162] Preferably, when the pen holder 61 is in the pop-out position, the elastic element 62 is in a deformed state to push the pen holder 61 to the pop-out position. This allows the pen holder 61 to be more stably positioned in the pop-out position, thereby increasing the operational reliability of the storage tube 100.
