[0051] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0052] In the description of the embodiments of this application, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship that the product of this application is usually placed in when in use, or the orientation or positional relationship that is commonly understood by those skilled in the art. It is only for the convenience of describing this application and simplifying the description, and is not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.

[0053] like Figures 1 to 12 The present invention provides a tablet computer stand 100, which includes a support column 10, a rotating component 20, and a fixed base 30.

[0054] like Figure 2 , Figure 3 and Figure 9 As shown, the support column 10 is fixed to the desktop. The top of the support column 10 is provided with a rotating hole 21 that connects to the support space 3 inside the support column 10. The bottom of the rotating component 20 has a rotating column 6 that can rotate horizontally through the rotating hole 21, and the end of the rotating column 6 is limited to the support space 3.

[0055] The top of the rotating component 20 is provided with an inclined surface 5, and a locking mechanism 7 is provided on the inclined surface 5. The back of the fixed seat 30 is detachably locked to the top of the rotating component 20 with the locking mechanism 7.

[0056] The front of the mounting base 30 is provided with a tablet mounting slot 8, and a locking device 81 is provided on the tablet mounting slot 8 so that the tablet computer 200 can be detachably locked in the tablet mounting slot 8. The locking device 81 is existing technology, and its specific structure will not be described in detail here.

[0057] See here. Figure 12 When the tablet computer 200 is fixed in the mounting base 30, since the support column 10 is fixed to the desktop, when consumers in different directions want to view the tablet computer 200, they can rotate the mounting base 30 and the rotating component 20 horizontally by rotating the column 6, so that the screen of the tablet computer 200 is always tilted vertically, while the horizontal direction can be adjusted to different orientations to face consumers in different positions.

[0058] like Figure 2 , Figure 5 and Figure 10 As shown, in this embodiment, the upper part of the support column 10 is cylindrical, and the lower part of the support column 10 is a frustum-shaped cone with a gradually expanding diameter. The support space 3 of the support column 10 runs through the upper and lower ends of the support column 10. The inner wall of the upper part of the support space 3 is provided with a first installation step 31 and a second installation step 32 at intervals near the upper opening 101 of the support column 10.

[0059] like Figure 5 As shown, the first mounting step 31 is located inside the upper opening 101 and can be welded to and fixed to a mounting plate 1. The mounting plate 1 has a mounting hole 11 in the middle, and the side wall of the mounting hole 11 is recessed with a plurality of mounting limiting holes 111 at intervals. A mounting post 2 is installed between the mounting plate 1 and the upper opening 101. The mounting post 2 has the aforementioned rotating hole 21 inside. The outer wall of the mounting post 2 is spaced from the inner wall of the upper part of the support space 3. The bottom of the outer wall of the mounting post 2 has a recessed mounting part 22, and the mounting part 22 has a plurality of circumferentially protruding limiting protrusions 221. The mounting part 22 at the bottom of the mounting post 2 is inserted into the mounting hole 11 of the mounting plate 1, and each limiting protrusion 221 is engaged with the mounting limiting holes 111 of the mounting hole 11 to fix the mounting post 2 to the mounting plate 1 in a non-rotatable manner.

[0060] See Figure 10 After the rotating column 6 of the rotating component 20 is inserted into the rotating hole 21 of the mounting column 2, its end is locked to the bottom of the mounting plate 1; the end of the rotating column 6 can be locked with a nylon gasket 61, a limiting gasket 62, a wave washer 63 and a nut 64 in sequence from top to bottom, so as to form a limit with the mounting plate 1 and the mounting column 2.

[0061] like Figure 4 and Figure 6 As shown, at least two abutting protrusions 23 are provided circumferentially at intervals around the rotating hole 21 on the top surface of the mounting post 2. In this embodiment, four abutting protrusions 23 are provided at 90° intervals circumferentially. The top surface of the abutting protrusions 23 is close to the bottom surface of the rotating component 20 to reduce the contact area between the bottom surface of the rotating component 20 and the top surface of the mounting post 2, thereby reducing the rotational friction.

[0062] The outer periphery of the rotating hole 21 on the top surface of the mounting column 2 is also recessed with an arc-shaped sliding groove 24 coaxial with the rotating hole 21. The bottom surface of the rotating component 20 is provided with a sliding block 201 protruding from the outer periphery of the rotating column 6. The sliding block 201 passes downward through the sliding groove 24 and slides in the sliding groove 24 as the rotating component 20 rotates. In this embodiment, the sliding groove 24 can be a semi-circular arc shape, thereby allowing the rotating component 20 to rotate up to 180° in the horizontal direction.

[0063] The outer wall of the mounting post 2 is provided with two positioning components 25. Each positioning component 25 includes two semi-circular protrusions 251 protruding from the outer wall of the mounting post 2, and a positioning groove 252 is formed between the two semi-circular protrusions 251. The bottom surface of the rotating member 20 is provided with a positioning block 202 protruding downwards corresponding to the outer side of the two positioning grooves 252. The positioning block 202 is radially movable so that it can pass over the semi-circular protrusions 251 and be positioned and locked in the positioning groove 252 as the rotating member 20 rotates. In this embodiment, the two positioning components 25 are respectively corresponding to the two arc-shaped ends of the sliding groove 24, and one of the positioning blocks 202 is located radially outside the sliding block 201. The bottom surface of the rotating member 20 is provided with a relief hole 203 corresponding to the positioning block 202 to facilitate the radial movement of the positioning block 202.

[0064] like Figure 2 , Figure 5 and Figure 10 As shown, a ring-shaped light-emitting component 9 can be installed near the upper opening 101 at the second mounting step 32. The light-emitting component 9 includes a ring-shaped light-emitting plate 91 and a ring-shaped light-transmitting lamp cover 92. The ring-shaped light-emitting plate 91 is installed at the second mounting step 32 and surrounds the outer periphery of the mounting column 2. The ring-shaped light-emitting plate 91 has inner and outer rings of light-emitting beads 911. The light-emitting surface of each light-emitting bead 911 is higher than the top surface of the support column 10 and faces the radially outward side of the support column 10. The inner and outer rings of light-emitting beads 911 have light-emitting surfaces that are higher than the top surface of the support column 10 and face the radially outward side of the support column 10. The LED beads 911 are spaced apart to ensure that the light-emitting surface of the inner ring is not blocked by the outer ring. The LED beads 911 in the inner and outer rings can be different colors or all of them can be multi-colored LED beads. The annular light-transmitting cover 92 is placed on the top surface, outer peripheral surface and inner peripheral surface of the annular light-emitting plate 91 to protect each LED bead 911 and to provide light uniformity and light guidance. The outer peripheral diameter of the annular light-transmitting cover 92 can be the same as the outer diameter of the upper part of the support column 10 and is sandwiched between the rotating part 20 and the support column 10.

[0065] like Figure 5 As shown, the inner peripheral wall of the annular light-transmitting lamp cover 92 is provided with a limiting component 921 corresponding to the positioning component 25 of the mounting column 2. The limiting component 921 includes two limiting grooves 9211, which are used to align and lock the two semi-circular protrusions 251 of the positioning component 25. Thus, when the annular light-transmitting lamp cover 92 is covered by the annular light-emitting plate 91 and sandwiched between the rotating member 20 and the support column 10, it can be limited by the limiting component 921 and the non-rotating mounting column 2 to prevent the annular light-transmitting lamp cover 92 and the annular light-emitting plate 91 from rotating when the rotating member 20 rotates.

[0066] The mounting plate 1 has a notch 12 through which the connecting wire (not shown) for powering the annular light-emitting plate 91 passes.

[0067] like Figure 1 , Figure 3 , Figure 10 and Figure 11As shown, the tablet computer stand 100 in this embodiment also has a charging module 40 inside to provide charging function for the tablet computer 200, provide battery life support for the tablet computer 200 that is suspended in the air, and avoid the charging cable 50 being exposed.

[0068] The charging module 40 includes a fixed base adapter 401 disposed on the fixed base 30 and a charging part 402 disposed on the mounting inclined surface 5 of the rotating member 20. The support column 10 supports the space 3 and a control circuit board 60 is provided. The fixed base adapter 401 is electrically connected to the charging part 402, and the charging part 402 is electrically connected to the control circuit board 60. The control circuit board 60 is connected to the mains power to charge the tablet computer 200.

[0069] The mounting adapter 401 includes a first charging head 4011 located in the front flat mounting slot 8 and a second charging head 4012 located on the back of the mounting base 30. The first charging head 4011 is a small connector structure adapted to common charging cable connectors 50, and the second charging head 4012 can be a large connector, both located in the middle of the mounting base 30.

[0070] like Figure 1 As shown, the tablet mounting slot 8 is also equipped with the charging cable 50 for connecting the first charging head 4011 and the charging port 2001 located on the side of the tablet computer 200. Several suction cups 82 are provided around the tablet mounting slot 8 for fixing and adsorbing the tablet computer 200. An opening limiting groove 83 is provided on the supporting rib between the first charging head 4011 and the charging port 2001 near the side of the tablet computer 200. The distance between the opening 831 of the opening limiting groove 83 is slightly smaller than the wire diameter of the charging cable 50. The interior of the opening limiting groove 83 is a long strip-shaped through hole 832. The opening 831 is located in the middle of the long strip-shaped through hole 832, so that the charging cable 50 can be moved and limited within the opening limiting groove 83 after being inserted into the opening limiting groove 83 through the opening 831, avoiding the charging cable 50 being directly taken away from the tablet mounting slot 8 when the tablet computer 200 is removed, thus preventing the charging cable 50 from being lost.

[0071] The fixed base 30 is designed to be detachably locked to the rotating part 20 in conjunction with the locking mechanism 7.

[0072] like Figure 6 and Figure 11As shown, specifically, the rotating component 20 includes a housing 4, the mounting inclined surface 5, and the rotating column 6. The housing 4 has an installation space 41, the top of which is open and can be closed using the mounting inclined surface 5. The bottom of the installation space 41 has a rotating column mounting hole 411. The rotating column 6 has a hollow structure, meaning it has a hollow channel 65 that runs vertically through it. The top of the rotating column 6 has a radially outwardly protruding limiting edge 66, allowing the rotating column 6 to pass through the opening from top to bottom and then be confined within the rotating column mounting hole 411. The limiting edge 66 has a circumferentially recessed positioning hole 661, which, in relation to the positioning columns 412 located around the rotating column mounting hole 411, ensures a non-rotatable connection between the rotating column 6 and the rotating column mounting hole 411.

[0073] The charging unit 402 includes a third charging head 4021 disposed on the mounting inclined surface 5 of the rotating member 20. The third charging head 4021 is used to connect with the second charging head 4012 disposed on the back of the fixed base 30. The second charging head 4012 of the fixed base adapter 401 and the third charging head 4021 of the charging unit 402 are mutually plugged and adapted, and both have a large-sized structure for easy plugging and can also be provided with a magnetic attraction structure.

[0074] Furthermore, the third charging head 4021 is fixedly connected to the third charging head circuit board 4022 located in the mounting space 41 of the outer casing 4. The connecting wire of the third charging head circuit board 4022 (not shown in the figure) passes through the hollow channel 65 of the rotating column 6 and is connected to the control circuit board 60 in the support space 3 to achieve electrical conduction. The connecting wire of the annular light-emitting plate 91 of the light-emitting component 9 is also connected to the control circuit board 60 and is powered by the control circuit board 60.

[0075] The bottom of the support column 10 is provided with a base plate 103 to close the lower opening 102 of the support space 3. The control circuit board 60 is connected to the base plate 103 and located within the lower part of the support space 3. The control circuit board 60 also has a side interface 601, which corresponds to a wiring hole 104 located on the lower side wall of the support column 10 for easy external power connection. A fixing plate 70 can be locked below the base plate 103 for secure connection to the desktop.

[0076] like Figure 11 As shown, the locking mechanism 7 includes sliding limit blocks 71 on both sides of the mounting slope 5, an induction electromagnet 72 and an induction coil 73 in the mounting space 41, a movable locking block 74 installed in the middle of the mounting slope 5, and two sliding grooves 75 on both sides of the back of the fixed base 30.

[0077] The bottom of the two sliding grooves 75 on the back of the fixed base 30 is provided with slots 751. The slots 751 are located on the top of the sliding limit block 71 on the mounting slope 5 of the rotating component 20, so that the two sliding grooves 75 of the fixed base 30 can be slidably installed on the sliding limit block 71 from top to bottom, so that the fixed base 30 is installed on the mounting slope 5 of the rotating component 20. At the same time, the second charging head 4012 is inserted into the third charging head 4021 from top to bottom.

[0078] The movable locking block 74 has a hinge part 741 in the middle, which is hinged between two sliding limit blocks 71. An upper movable part 742 and a lower movable part 743 are respectively provided on the upper and lower sides of the hinge part 741. A movable hole 51 is provided on the mounting slope 5 below the upper movable part 742. The induction electromagnet 72 is installed below the movable hole 51. The induction electromagnet 72 includes an electromagnetic coil 721. The electromagnetic coil 721 has a movable iron core 722 that can move up and down. When the electromagnetic coil 721 is energized, it can control the movable iron core 722 to extend upward into the movable hole 51 and lift the upper movable part 742. At this time, the lower movable part 743 moves downward and fits tightly against the mounting slope 5. When the electromagnetic coil 721 is energized with a reverse current, it can control the movable electromagnet to exit the movable hole 51.

[0079] A spring 52 is provided between the lower movable part 743 and the mounting slope 5. When the moving iron core 722 is not inserted into the movable hole 51, the spring 52 pushes the lower movable part 743 upward so that after the fixed seat 30 slides down and is installed on the mounting slope 5, the lower movable part 743 can be tilted up and abut against the stop 301 at the bottom of the back of the fixed seat 30, limiting the upward movement of the fixed seat 30 and locking the fixed seat 30. When unlocking is required, the moving iron core 722 is activated, pushing up the upper movable part 742 and driving the lower movable part 743 downward, releasing the limit on the stop 301, so that the fixed seat 30 can slide up and exit the mounting slope 5.

[0080] The front end of the mounting slope 5 is lower than the rear end, so the rear area of ​​the mounting space 41 of the rotating component 20 can be used to install the induction coil 73. The induction coil 73 is ring-shaped, and the top of the induction coil 73 is locked in the two slots 413 provided on the rear side of the mounting space 41. The third charging head circuit board 4022 extends into the middle 731 of the ring of the induction coil 73. The induction electromagnet 72 is located on the front side of the third charging head circuit board 4022 and partially extends into the hollow channel 65 of the rotating column 6. The hollow channel 65 is also provided with a side clearance hole 651 to avoid the moving iron core 722, thereby saving the mounting space 41 and making the rotating component 20 as a whole smaller.

[0081] The rear part of the rotating member 20 protrudes outward to form a sensing part 204 corresponding to the induction coil 73, so as to visually indicate that this is the sensing area.

[0082] The connecting wires of the induction electromagnet 72 and the induction coil 73 both pass through the hollow channel 65 of the rotating column 6 and are electrically connected to the control circuit board 60. After the induction coil 73 senses the card (not shown), it sends a signal to the control circuit board 60. The control circuit board 60 then controls the moving iron core 722 of the induction electromagnet 72 to move, thereby pressing against the upper movable part 742 of the movable card block 74 to unlock it, which can effectively prevent theft.

[0083] At the same time, the control circuit board 60 controls the light-emitting component 9 to change the light emission, indicating that the fixing base 30 and the tablet computer 200 can be removed from the mounting slope 5 of the rotating component 20.

[0084] Since the connecting wires pass through the hollow channel 65, in order to prevent the connecting wires from getting tangled when the fixed base 30 and the rotating part 20 rotate, this embodiment provides a partition 652 in the hollow channel 65 to divide the hollow channel 65 into two chambers 653. The connecting wire of the induction electromagnet 72 can pass through one chamber 653 alone, and the connecting wire of the induction component and the charging part 402 can pass through one chamber 653 alone.

[0085] The tablet computer stand 100 of the present invention can be installed using the following method at the time of manufacture to improve product manufacturing and assembly efficiency.

[0086] (1) After the rotating column 6 is inserted into the opening of the mounting space 41 of the rotating component 20, it passes through the mounting hole 411 of the rotating column and is fixed by the positioning columns 412 and positioning holes 661 of the limiting edge 66; at the same time, the mounting plate 1 is fixed to the first mounting step 31 of the upper opening 101 of the support column 10 by welding or other means, and the bottom mounting part 22 of the mounting column 2 is inserted and positioned in the mounting hole 11 of the mounting plate 1 to achieve the snap-fit ​​fixation.

[0087] (2) After passing the connecting wire of the ring light-emitting plate 91 through the notch 12 of the mounting plate 1, place it in the support space 3, then put the ring light-emitting plate 91 on the rotating column 6 and place it at the second mounting step 32, and then cover it with the ring light-transmitting cover 92.

[0088] (3) Insert the rotating column 6 of the rotating component 20 through the rotating hole 21 of the mounting column 2 of the support column 10, and at the same time, align the slider of the rotating component 20 into the sliding groove 24. Place the nylon gasket 61, the limiting gasket 62, the wave washer 63 and the nut 64 into the support space 3 from the lower opening 102 of the support column 10 in sequence. Place the nylon gasket 61, the limiting gasket 62 and the wave washer 63 on the end of the rotating column 6, and then lock the nut 64 to rotate the rotating column 6 of the rotating component 20 to the rotating hole 21 of the support column 10.

[0089] (4) The induction coil 73 is installed on the rear side of the mounting space 41 of the rotating part 20. The charging part 402 is installed on the mounting slope 5. The connecting wires of the induction coil 73 and the charging part 402 are passed through one of the chambers 653 of the hollow channel 65 of the rotating column 6. The induction electromagnet 72 is installed below the mounting slope 5. The movable block 74 and the spring 52 are installed above the mounting slope 5. The connecting wire of the induction electromagnet 72 is passed through another chamber 653. Finally, the mounting slope 5 is fixed and locked to the opening of the mounting space 41.

[0090] (5) Connect the control circuit board 60 to each connecting wire and fix it on the base plate 103, then close and fix the base plate 103 to the lower opening 102 of the support column 10. Optional locking plate 70 is provided below the base plate 103.

[0091] (6) Slide and lock the assembled fixed seat 30 from top to bottom along the mounting slope 5 so that the fixed seat 30 is fixedly located at the lower movable part 743 of the movable block 74.

All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, equivalent changes and modifications without departing from the principle of the present invention should still fall within the scope of protection of the present invention.
