[0046] Please refer to Figure 1 An embodiment of the present application provides an expansion frame 100 for a tablet computer, which comprises a frame body 10 and a locking assembly 20. The frame body 10 comprises a fixed frame 11 and a movable frame 12. The fixed frame 11 is arranged in a bent manner. One end of the movable frame 12 is rotationally connected to one end of the fixed frame 11. The other end of the movable frame 12 is detachably connected to the other end of the fixed frame 11. The movable frame 12 can be rotated relative to the fixed frame 11 to an open state to insert or remove the tablet computer, or to a closed state to form a closed frame 10 for accommodating the tablet computer. The locking assembly 20 is arranged between the fixed frame 11 and the movable frame 12, and is used for locking or unlocking the fixed frame 11 and the movable frame 12.

[0047] Another end of the movable frame 12 is connected with another end of the fixed frame 11 through a detachable connection structure, for example, a buckle connection, a magnetic attraction connection or a bolt connection, etc. This detachable connection mode facilitates the user to quickly open or close the movable frame 12 when needed, while ensuring the tightness and reliability of the connection in the closed state.

[0048] When the movable frame 12 is rotated to the open state relative to the fixed frame 11, the expansion frame 100 forms an opening, which facilitates the user to insert or take out the tablet computer; and when the movable frame 12 is rotated to the closed state, it forms a closed frame body 10 together with the fixed frame 11 for accommodating the tablet computer. The closed frame body 10 can tightly fit the edge of the tablet computer, effectively surround and fix the tablet computer from all around, and prevent displacement of the tablet computer in the frame body 10.

[0049] The locking assembly 20 is arranged between the fixed frame 11 and the movable frame 12, which can adopt a mechanical lock buckle 21, an electronic lock or other reliable locking mechanism. When the movable frame 12 is rotated to the closed state, the locking assembly 20 can automatically or through the user's simple operation (such as pressing, rotating, magnetic attraction, etc.) firmly lock the fixed frame 11 and the movable frame 12 together, forming a stable overall structure, ensuring that the movable frame 12 will not be accidentally opened during use, thereby ensuring the safety and stability of the tablet computer in the expansion frame 100. When the user needs to take out the tablet computer, through the corresponding unlocking operation, the locking assembly 20 can quickly release the locking of the fixed frame 11 and the movable frame 12, so that the movable frame 12 can be smoothly rotated to the open state, facilitating the user to take out the tablet computer.

[0050] Compared with the traditional expansion frame which only relies on two spring clamping fixing points, the closed frame body 10 structure formed by the fixed frame 11 and the movable frame 12 of the expansion frame 100 of the embodiment can fix and surround the tablet computer from all around. This multi-directional fixing mode greatly enhances the stability and firmness of the tablet computer in the expansion frame 100, effectively resists the vibration, collision and movement that may be encountered in daily use, greatly reduces the risk of the tablet computer falling out of the expansion frame 100, effectively protects the physical safety of the tablet computer, avoids the damage and economic loss caused by falling out, provides a more reliable and safe use environment for the user, and significantly improves the use safety.

[0051] Further, the embodiment of the present application is through the rotating connection and detachable connection of the movable frame 12, cooperating with the locking assembly 20, when the user inserts or takes out the tablet computer, the user does not need to rely on both hands to perform the cumbersome operation as the traditional docking station 100. The user can easily open the movable frame 12 with one hand, put in or take out the tablet computer, and then operate the movable frame 12 to be closed with one hand and fixed through the locking assembly 20. The whole process is simple, fast and efficient.

[0052] Please refer to Figure 2 In some embodiments, the fixed frame 11 includes a first frame 111, a second frame 112 and a third frame 113 connected in sequence, the first frame 111 and the third frame 113 are oppositely arranged with a spacing, one end of the movable frame 12 is rotatably connected to the first frame 111 away from the second frame 112, and the other end of the movable frame 12 is detachably connected to the third frame 113 away from the second frame 112.

[0053] In some embodiments, the fixed frame 11 includes a first frame 111, a second frame 112 and a third frame 113 connected in sequence, the first frame 111 and the third frame 113 are oppositely arranged with a spacing, one end of the movable frame 12 is rotatably connected to the first frame 111 away from the second frame 112, and the other end of the movable frame 12 is detachably connected to the third frame 113 away from the second frame 112.

[0054] When the movable frame 12 is in the closed state, it forms a closed frame 10 space together with the fixed frame 11, and the internal size is accurately matched with the outline of the tablet computer. The first frame 111, the second frame 112, the third frame 113 and the closed movable frame 12 are in close contact with the four edges of the tablet computer respectively, and apply moderate pressure to the tablet computer from all directions, so that the tablet computer is stably fixed in the docking station 100, preventing displacement or shaking when subjected to external force, and ensuring that the tablet computer and the docking station 100 become a relatively stable whole, so as to realize the stable expansion function.

[0055] In the embodiment, the fixed frame 11 is in a U-shaped structure, and the movable frame 12 is used to open and close the opening of the U-shaped structure; in other embodiments, the fixed frame 11 can also be in an L-shaped structure, and the movable frame 12 is correspondingly in an L-shaped structure, as long as it can form a closed frame 10 for clamping the tablet computer, which is not limited in the embodiment of the present application.

[0056] Please continue to refer to Figure 2In some embodiments, the locking assembly 20 comprises a locking buckle 21 arranged on one of the third frame 113 and the movable frame 12, and a locking slot 22 arranged on the other one of the third frame 113 and the movable frame 12, the locking buckle 21 and the locking slot 22 being matched to achieve detachable connection between the movable frame 12 and the fixed frame 11.

[0057] In some embodiments, the locking buckle 21 is arranged on one of the third frame 113 and the movable frame 12, and the locking slot 22 is arranged on the other one of the third frame 113 and the movable frame 12, the two being matched to achieve efficient and reliable detachable connection between the movable frame 12 and the fixed frame 11.

[0058] In the process of installing the tablet computer, the user first opens the movable frame 12, and then puts the tablet computer into the movable frame 12. Then, the user rotates the movable frame 12 to gradually close the movable frame 12 to the third frame 113. When the locking buckle 21 and the locking slot 22 are close to alignment, the user gently presses the movable frame 12, and the locking buckle 21 is smoothly slid into the locking slot 22 to complete locking. The whole process does not require complex tools or cumbersome steps, and can be completed by single-handed operation, which is convenient and fast.

[0059] When the tablet computer needs to be taken out, the user only needs to apply appropriate external force to overcome the friction between the locking buckle 21 and the locking slot 22, so that the locking buckle 21 is separated from the locking slot 22, and the movable frame 12 is opened to take out the tablet computer, which is direct and efficient.

[0060] Please refer to Figures 2 to 4 In some embodiments, the locking slot 22 is arranged at an end of the movable frame 12 away from the first frame 111.

[0061] The locking buckle 21 comprises a locking piece 211, a control piece 212 and an elastic piece 213. The locking piece 211 is movably arranged at an end of the third frame 113 away from the second frame 112, and at least partially exposed outside the third frame 113. The exposed part of the locking piece 211 is provided with a locking hook 2111 for buckling cooperation with the locking slot 22.

[0062] The control piece 212 is movably arranged on the third frame 113 and abuts against the locking piece 211. The control piece 212 is at least partially exposed outside the third frame 113, so as to drive the locking hook 2111 to separate from the locking slot 22 under the action of external force.

[0063] The elastic piece 213 elastically acts on the locking piece 211, so as to drive the control piece 212 to return to the original position when the external force is removed, and the locking hook 2111 is buckled into the locking slot 22.

[0064] In this embodiment, the locking groove 22 is arranged at the end of the movable frame 12 away from the first frame 111, and the shape of the locking groove 22 can be designed as a groove with a certain depth and width to ensure close cooperation with the locking buckle 21. The locking member 211 is movably mounted at the end of the third frame 113 away from the second frame 112, and the part exposed to the third frame 113 is designed as a hook structure 2111, which is curved and has a curvature and size that perfectly match the locking groove 22, ensuring a tight and stable connection when buckling.

[0065] Preferably, the locking groove 22 can be integrally formed on the movable frame 12 by high-precision mold injection process, using high-strength and flexible engineering plastic material to ensure its structural stability and durability. The main part of the locking member 211 can be made of metal material, which has sufficient strength and rigidity to withstand the force during locking and ensure good locking performance during long-term use.

[0066] In this embodiment, the control member 212 is partially exposed to the third frame 113, which is convenient for users to operate. When the user needs to unlock the expansion frame 100, only a moderate external force needs to be applied to the exposed part of the control member 212, such as gentle pressing or pushing, and the control member 212 will move inward along the preset track and transfer this external force to the locking member 211. Due to the close contact design between the control member 212 and the locking member 211, the effective transfer of the external force can be ensured, so that the locking member 211 overcomes the elastic force of the elastic member 213, thereby driving the hook 2111 to disengage from the locking groove 22, achieving the unlocking of the movable frame 12 and the fixed frame 11. The whole process is simple and fast, and does not require complex tools.

[0067] The elastic member 213 can be a spring or other element with elastic properties. Under normal conditions, the elastic member 213 always exerts an outward elastic force on the locking member 211, so that the hook 2111 remains in close buckling cooperation with the locking groove 22. When the external force acts on the control member 212 and causes the hook 2111 to disengage from the locking groove 22, as soon as the external force is removed, the elastic restoring force of the elastic member 213 will act to push the locking member 211 outward, while driving the control member 212 back to the original position, ensuring that the hook 2111 can accurately and reliably re-enter the locking groove 22, achieving fast and reliable relocking. This automatic reset function not only improves the convenience of operation, but also ensures the consistency and stability of each locking operation, effectively avoiding problems such as locking failure or loosening caused by improper human operation.

[0068] Through the locking assembly 20 in the embodiment, efficient and stable connection and separation operation between the tablet computer and the docking frame 100 is achieved. In actual use, the user can easily install the tablet computer in the docking frame 100 and achieve reliable fixation through simple operation, which can effectively prevent accidental falling of the tablet computer in daily office, mobile use or other various scenes, and provide a safer and more convenient use experience for the user. At the same time, the durability and stability of the locking assembly 20 also ensure the reliability of the docking frame 100 in the long-term use process, and reduce the maintenance cost and replacement frequency.

[0069] Please continue to refer to Figure 4 In some embodiments, the third side frame 113 is provided with a containing cavity 1131, one side wall of the third side frame 113 is provided with a first through hole communicating with the containing cavity 1131, and the other side wall of the third side frame 113 is provided with a second through hole communicating with the containing cavity 1131.

[0070] The locking piece 211 is rotatably arranged in the containing cavity 1131, the locking hook 2111 extends out of the first through hole for buckling cooperation with the locking groove 22, and the control piece 212 penetrates the second through hole and abuts against the locking piece 211.

[0071] In the embodiment, the third side frame 113 serves as a bearing component of the locking assembly 20, and an internal containing cavity 1131 is constructed, which provides a stable basic environment for installation and cooperative work of subsequent components, can compactly accommodate key components such as the locking piece 211, the control piece 212 and the elastic piece 213, and ensures that the components do not interfere with each other during movement and smoothly and unobstructedly perform the predetermined functions.

[0072] The first through hole is arranged on one side wall of the third side frame 113 and communicates with the containing cavity 1131, allowing the locking hook 2111 of the locking piece 211 to smoothly pass through, for precise buckling cooperation with the locking groove 22 on the movable side frame 12. At the same time, the second through hole is arranged on the other side wall of the third side frame 113 and communicates with the containing cavity 1131, the control piece 212 penetrates the second through hole and abuts against the locking piece 211, ensuring that external force can be transmitted from the control piece 212 to the locking piece 211, so as to realize accurate control of the locking hook 2111. When the user applies external force to the control piece 212 exposed outside the third side frame 113, the external force is transmitted to the locking piece 211 along the axial direction of the second through hole through the control piece 212, overcoming the elastic force of the elastic piece 213, so that the locking hook 2111 can quickly and accurately separate from the locking groove 22, completing the unlocking operation and facilitating the user to take out the tablet computer.

[0073] In order to optimize the rotation characteristics of the movable frame 12, in some embodiments, one end of the movable frame 12 is rotationally connected to the first frame 111 through a first rotating shaft 121, and a first damping member 122 is arranged around the first rotating shaft 121 and located between the first frame 111 and the movable frame 12, tightly adhering to the contact position of the first rotating shaft 121 and the movable frame 12 to form a buffer and resistance layer.

[0074] When the user rotates the movable frame 12, the first damping member 122 generates a certain friction force to prevent the movable frame 12 from rapidly rotating due to its own gravity or external force, thereby achieving the stability and controllability of the rotation process of the movable frame 12. For example, when the user slowly opens the movable frame 12 to insert the tablet computer, the first damping member 122 can slowly open the movable frame 12 to avoid the collision damage to the tablet computer or the expansion frame 100 caused by sudden and rapid rotation; similarly, when closing the movable frame 12, the first damping member 122 can also make the movable frame 12 slowly and smoothly adhere to the fixed frame 11 to ensure that the lock buckle 21 and the lock groove 22 can accurately and correctly complete the buckling cooperation, thereby improving the success rate and stability of the locking operation.

[0075] Preferably, the first damping member 122 can be made of rubber material with high elasticity and wear resistance, which can provide stable resistance during the rotation of the movable frame 12 and is very durable.

[0076] In some embodiments, the frame 10 is provided with a storage slot 101 for storing a stylus, and a magnet 102 is arranged in the storage slot 101 for adsorbing the stylus.

[0077] In this embodiment, the frame 10 as the main structure of the tablet computer expansion frame 100 is provided with a storage slot 101 for storing a stylus, effectively solving the problem of easy loss and inconvenience of carrying the stylus, and further improving the overall practicality and user experience of the tablet computer expansion frame 100.

[0078] In order to further enhance the fixing effect of the stylus in the storage slot 101 and prevent it from being separated from the storage position due to vibration or accidental collision, a magnet 102 is arranged in the storage slot 101 for adsorbing the stylus. The magnet 102 can be made of neodymium iron boron material with high magnetic strength and stability, and is installed on the bottom or side wall of the storage slot 101. The stylus is tightly adsorbed in the storage slot 101 by the magnetic force. When the stylus approaches the storage slot 101, the magnetic force generated by the magnet 102 can quickly adsorb the stylus in place, so that the stylus and the storage slot 101 form a stable connection. Even in a relatively bumpy environment, the stylus can be firmly kept in the storage slot 101, avoiding loss or damage, and providing great convenience for the user.

[0079] Preferably, the present embodiment adopts the structure of the receiving groove 101 provided with multiple hooks 109, which are located at specific positions of the frame 10, such as the upper edge or the side edge of the frame 10, to ensure that the stylus is provided with a safe and easily accessible space without affecting other functional areas of the tablet computer. The user only needs to align the stylus with the opening direction of the hooks 109 and gently put it in, without the need for accurate alignment or forceful plugging and unplugging, which can be easily completed with one hand, greatly improving the user's efficiency.

[0080] In some embodiments, the hooks 109 can be made of materials with certain elasticity and toughness, such as high-strength engineering plastics or specially treated metal alloys, with a curved arc closely fitted to the contour of the stylus. When the stylus is inserted into the receiving groove 101, the multiple hooks 109 embrace the stylus to firmly fix it in the receiving groove 101.

[0081] Compared with the traditional straight slot or simple clamping slot type receiving structure, the hook 109 type receiving groove 101 structure of the present embodiment can adapt to styluses of different diameters and shapes, with stronger versatility.

[0082] Please refer to Figure 5 and Figure 6 In some embodiments, the expansion frame 100 further includes a support frame 30, which includes a connecting member 31 and a support member 32, the connecting member 31 is connected with the fixed frame 11, and the support member 32 is rotationally connected with the connecting member 31.

[0083] The connecting member 31 serves as a bridge between the fixed frame 11 and the support member 32, and is rigidly connected with the fixed frame 11 by a stable connection method such as welding, riveting, bolt connection, etc., to ensure that when bearing the force of the support member 32 and the weight of the tablet computer, the force can be evenly distributed to the fixed frame 11, ensuring the stability of the entire structure.

[0084] The rotational connection between the support member 32 and the connecting member 31 is based on the principle of mechanical rotation, which can be achieved by a pin shaft and a shaft sleeve, or a hinge structure with damping, so that the support member 32 can rotate flexibly relative to the connecting member 31 within a certain angle range with the connecting point as the axis. This rotational design allows the user to manually adjust the angle of the support member 32 according to the actual use scenario and personal needs, thereby changing the inclination and height of the tablet computer to adapt to different operation modes such as video watching, text input, and graphic design, thereby meeting the diversified needs of users in different work and entertainment scenarios and improving the user experience.

[0085] When the user needs to adjust the angle of the tablet, only need to exert an external force on the support member 32, overcome the friction of the rotating connection or the presence of damping force, so that the support member 32 rotates around the rotating shaft to the desired angle position, and then rely on the friction, damping force or additional angle locking device (such as a card slot and a card block, threaded locking, etc.) to fix the support member 32 at the position, realize the stable support of the tablet.

[0086] When the support frame 30 is not needed, the support member 32 can be rotated to be accommodated in the position adhering to the fixed frame 11, or folded into a compact shape, thereby greatly reducing the overall space occupied by the expansion frame 100, facilitating the user to carry and store.

[0087] In some embodiments, the support member 32 is rotatably connected with the connecting member 31 through a second rotating shaft 33, the periphery of the second rotating shaft 33 is provided with a second damping member 34, and the second damping member 34 is located between the support member 32 and the connecting member 31; and / or,

[0088] The expansion frame 100 further comprises a magnetic attraction assembly 40, the magnetic attraction assembly 40 comprises magnetic members 41 and magnetic attraction members 42 arranged separately on the support member 32 and the connecting member 31, and the magnetic members 41 and the magnetic attraction members 42 are connected to support the support member 32 and the connecting member 31; and / or,

[0089] The end of the support member 32 away from the connecting member 31 is provided with an anti-skid member 321; and / or,

[0090] The side of the connecting member 31 facing the support member 32 is provided with a buffer member 311; and / or,

[0091] The connecting member 31 is provided with a threaded hole 312 for externally connecting auxiliary accessories.

[0092] The support member 32 and the connecting member 31 are relatively rotatable through the second rotating shaft 33, the second rotating shaft 33 serves as the axis of rotation, ensuring that the support member 32 can change the angle around it flexibly. The second damping member 34 utilizes the elastic and frictional properties of the material to generate a resistance torque during the rotation of the support member 32. When an external force acts on the support member 32 to rotate it, the damping member will be elastically deformed, and at the same time, due to the friction between it and the support member 32 and the connecting member 31, the rotating energy is consumed, so that the rotation speed of the support member 32 is controlled, and it can be relatively stable at any angle position, and will not swing randomly due to slight external force interference.

[0093] Based on the characteristics of the same sex repulsion and opposite sex attraction of magnetic materials, the magnetic piece 41 and the magnetic attraction piece 42 arranged on the support member 32 and the connecting member 31 respectively, when approaching to a certain distance, the magnetic field interacts to generate an attractive force, which can overcome the gravity of the support member 32 itself and a certain degree of external force disturbance, tightly adsorb and fix the support member 32 at a specific position opposite to the connecting member 31, ensure the connection stability between the two, and in the user operation process, through the guiding action of magnetic attraction, help the support member 32 to quickly and accurately position to the appropriate angle and position, realize the convenient angle adjustment and fixation.

[0094] The anti-skid piece 321 can adopt a rubber material with high friction coefficient, and the texture or protruding structure on its surface increases the micro contact area and mechanical engagement degree with the supporting plane, so as to resist the external force that may cause the expansion frame 100 to slide, thereby maintaining the static state of the expansion frame 100 on the supporting plane.

[0095] The buffer piece 311 can be made of an elastic material and has the ability to absorb and disperse energy. When the support member 32 approaches or collides with the connecting member 31 during rotation due to improper operation or external force impact, the buffer piece 311 will first be extruded to elastically deform. In this process, the energy of the impact force is stored in the form of elastic potential energy by the buffer piece 311, thereby slowing down the impact speed and force of the support member 32 on the connecting member 31, avoiding possible structural damage, loosening or deformation between the two due to hard collision, and playing a role in protecting the integrity of the support structure and prolonging the service life.

[0096] The threaded hole 312 on the connecting member 31 can adopt a standard thread specification, and the internal thread structure matches the threaded part of the external auxiliary accessory (such as an adjustable support extension rod, a small cooling fan bracket, an external lamp bracket, etc.). Through the screwing action, the external auxiliary accessory can be firmly connected to the connecting member 31, and the depth and angle of rotation can be adjusted as needed to realize stable connection and precise position adjustment of the external accessory with the expansion frame 100, thereby expanding the functional diversity of the expansion frame 100 and meeting the individual needs of users in different use scenarios.

[0097] In some embodiments, the inner side wall of the frame body 10 is provided with a slot 103 for inserting a tablet computer, and the slot 103 is provided with a gasket 104; and / or,

[0098] The first side frame 111 and / or the third side frame 113 is provided with a cold shoe interface 105; and / or,

[0099] The second side frame 112 and / or the movable side frame 12 is provided with a sound hole 106 opposite the speaker port of the tablet computer; and / or,

[0100] The second frame 112 and / or the movable frame 12 is provided with a mounting position 107 for externally connecting an auxiliary handle.

[0101] The inner side wall of the frame body 10 is provided with a slot 103, which can accurately insert the edge of the tablet computer and preliminarily position the tablet computer. The slot 103 design utilizes the space limitation principle of mechanical structure, and through accommodating the edge of the tablet computer, ensures that the tablet computer has a relatively fixed placement position in the expansion frame 100, and limits the movement of the tablet computer in the plane.

[0102] The gasket 104 in the slot 103 is usually made of soft and elastic material, such as silica gel or rubber. When the tablet computer is inserted into the slot 103, the gasket 104 will be extruded and elastically deformed. The deformation enables the gasket 104 to closely fit the edge of the tablet computer, which on the one hand increases the friction between the tablet computer and the slot 103, and further fixes the position of the tablet computer; on the other hand, the gasket 104 plays a buffering role, which can absorb the impact force that may be generated during the insertion process of the tablet computer, and the energy generated due to vibration and the like in daily use.

[0103] The cold shoe interface 105 adds powerful function expansion to the expansion frame 100. Users can conveniently connect various auxiliary devices related to photography and video recording, such as connecting an external microphone to improve audio quality when using the tablet computer to record a video, and connecting a fill light to improve lighting conditions, which greatly enriches the application scenarios of the tablet computer in multimedia creation.

[0104] When the tablet computer is placed in the expansion frame 100, the position of the loudspeaker port corresponds to the sound hole 106 on the second frame 112 and / or the movable frame 12, which can ensure that the sound of the tablet computer is clearly transmitted, and provides a good auditory experience for the user.

[0105] The second frame 112 and / or the movable frame 12 is provided with a mounting position 107 for externally connecting an auxiliary handle, which has a specific shape, size and connection structure, usually including a clamping groove, a threaded hole or a buckle, etc., for stable mechanical connection with the auxiliary handle. The mounting position 107 for externally connecting the auxiliary handle provides a more comfortable and convenient operation mode for the user, especially for gamers or users who need to perform precise operations for a long time. By installing the auxiliary handle, the user can obtain a better grip and operation control.

[0106] Please continue to refer to Figure 5 and Figure 6 In some embodiments, the expansion frame 100 is provided with a mounting slot 108 matched with the light shield 50, and the light shield 50 is detachably connected with the frame body 10 through the mounting slot 108.

[0107] The mounting groove 108 provided on the expansion frame 100 matches the structure of the light shield 50, and the detachable connection of the two is achieved by the fitting principle of mechanical structure. This connection mode is based on specific shape, size and connection mechanism, such as card slot and card block, sliding rail and sliding block, etc., so that the light shield 50 can be stably mounted in the mounting groove 108, and can be conveniently detached when needed. This design not only ensures the stability of the light shield 50 in use, but also meets the needs of users to flexibly mount and dismount the light shield 50 according to different use scenarios.

[0108] Preferably, the first frame 111 is provided with two mounting grooves 108, and the movable frame 12 and the second frame 112 are each provided with one mounting groove 108, thereby improving the connection stability of the light shield 50 and the expansion frame 100.

[0109] In this embodiment, the light shield 50 is detachably connected to the frame 10 through the mounting groove 108. In a strong light environment, the user can install the light shield 50 to effectively block the light, reduce screen reflection and glare, and improve the visibility of the tablet computer screen, so that the user can clearly view the screen content and improve the work and entertainment experience.

[0110] In some embodiments, the light shield 50 includes a first side plate 51 and a second side plate 52 arranged opposite to each other, and a third side plate 53 arranged between the first side plate 51 and the second side plate 52. The light shield 50 further includes a plurality of connecting members 54 for fixing the first side plate 51, the second side plate 52 and the third side plate 53 to the frame 10 respectively.

[0111] In this embodiment, the first side plate 51 and the second side plate 52 arranged opposite to each other can block the light from the side in the horizontal direction, reducing the interference of light from both sides into the tablet computer screen. The third side plate 53 located between them further provides light shielding protection in the vertical direction to prevent the light from above from directly shining on the screen. Through the synergistic effect of the three side plates, a relatively closed light shielding space is formed, which effectively reduces the influence of environmental light on the display effect of the tablet computer screen and improves the visibility and clarity of the screen.

[0112] In this embodiment, the plurality of connecting members 54 respectively fix the side plates, greatly improving the stability of the connection between the light shield 50 and the frame 10. Compared with the single connecting member 54 fixing the entire light shield 50, this decentralized fixing method can better withstand external forces, such as slight collisions and vibrations in daily use, reducing the possibility of loosening or damage of the light shield 50 due to uneven force, and ensuring that the light shield 50 can always remain in the correct position to provide stable light shielding protection for the tablet computer.

[0113] Preferably, the connecting piece 54 can be a Velcro, which is composed of a hook surface and a loop surface, and the connection is achieved by the mutual hooking of the hook surface and the loop surface. When the Velcro is used to fix the light shield 50, the light shield 50 is tightly connected with the frame 10 through the mounting slot 108. Specifically, one end of the Velcro is fixed on the side plate of the light shield 50, and the other end is pasted together with the corresponding surface (the hook surface and the loop surface cooperate with each other) of itself after passing through the mounting slot 108 on the frame 10. This connection method utilizes the hooking characteristics of the Velcro, can generate a larger friction force, and thus ensures that the light shield 50 can be stably fixed on the frame 10 under various use conditions.

[0114] When it is necessary to disassemble the light shield 50, the Velcro only needs to be gently torn, and then the light shield 50 can be easily taken off from the frame 10. This disassembly method is very flexible, and can facilitate the user to install or disassemble the light shield 50 at any time according to different light conditions and use scenes, so as to meet the diversified needs of the user.
